"setCPU for Root Users" saves the battery of your Android device

I've used setCPU for Root Users on my Nexus and now on my Desire HD to save battery : setCPU adjusts CPU speed to what is needed to perform the required tasks.



setCPU lets you adjust the lower and upper speed for your CPU. There's a "device selection" function in the menu that lets setCPU perform all the computing and suggest the appropriate values for your hardware. Here's a screenshot for the Desire HD.



The "Time in State" section from the "info" tab lists the time your phone has spent at different speeds. From the following screenshot, it appears the Desire HD CPU speed scales between 4 speeds from 245 MHz to 1024 MHz, spending most of its time between the upper and lower speed. The same screen on the Nexus One shows many different speeds, the Nexus spending most of its time on the lower speed (it naturally depends on how you use your Nexus).



As said in its name, setCPU for Root Users require root access.Rooting instructions can be found here :

Head to setCPU for Root Users's official page to get more informations on setCPU, specially on how to use setCPU to overclock / underclock your CPU.

Scan the following QR-code to download setCPU from the Android Market.

Nexus One - how to upgrade to CyanogenMod-6.1 V6.1.0-RC1 (10/27/2010) - instructions

I have just installed the CyanogenMod-6.1 first release candidate V6.1.0-N1-RC1 - 10/27/2010 (CyanogenMod-6.1 for Nexus One: Holy crap, it's full of AWESOME! V6.1.0-RC1 (10/27/2010)). Just keep in mind it is the 1st Release Candidate and as such, there are still some issues.

As the required radio image is still radio-4.06.00.12_7.img (Radio Firmware: 4.0.6.00.12_7 (FROYO RADIO, 4.06 OR HIGHER REQUIRED!)), I just have to upgrade to the new CyanogenMod-6.1 6.1.0-RC1.

I slightly depart from Cyanogen's instructions to upgrade :
  1. Do a Nandroid Backup !
    --->> steps 1) to 11) from Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions
  2. Wipe : I add this step as it prevents problems with Google Apps ; just remember to save everything before (don't forget to backup your Track Site's data).
    The wipe has to be done while in recovery mode just after the Nandroid backup (the previous step).
    Here are the detailled steps :
    • from the "Android system recovery" screen you are just after the step 11), scroll down to the "Wipe" item using the trackball, press on the trackball to select the item
    • On the "Choose wipe item" screen, choose the "Wipe cache" item (the 2nd one) using the trackball. The "Wipe cache" seems to be enough and does not need to reinstall all applications. Press the trackball a 2nd time to confirm on the question that appears on the back of the screen.
    • The wipe starts and takes a few seconds to complete. At the end of the wipe, the cyan screen is restored. Press Volume down button to return to the previous screen "Android system recovery".
    • follow on with step 14) of the upgrade procedure
  3. Install the CyanogenMod-6.1 6.1.0-N1-RC1 - 10/27/2010 ROM (your Google apps will be backed up automatically)
    --->> steps 14) to 16) from Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions. Don't reboot at this time and continue with the step below
  4. There's a 4th step to Cyanogen's instructions to install the most up to date version of Google apps : HDPI-20101025 (UPDATE 11/03 : Google Apps have been made available in a dedicated place : http://goo-inside.me/google-apps/ ; a wiki dedicated to Google Apps have been made available )
    --->> steps 15) and 18) from Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions. At the end, just reboot (or power-down by selecting the right option with the trackball in step 17)).

The detailed instructions to follow are pretty much the same as for Nexus One - how to upgrade to CyanogenMod-6 V6.0.0-RC1 (07/11/2010) - instructions to get the 6.1.0-N1-RC1 - 10/27/2010 ROM update-cm-6.1.0-RC1-N1-signed.zip installed.

Nexus One - how to upgrade to CyanogenMod-6 V6.0.0-RC1 (07/11/2010) - instructions

I have just installed the CyanogenMod-6 first release candidate V6.0.0-RC1 (07/11/2010) ([ROM] CyanogenMod-6 for Nexus One: Holy crap,full of AWESOME! V6.0.0-RC1 (07/11/2010) on XDA-developers) — the one that brings Froyo (Android 2.2) to my Nexus One.

As I had already installed the radio image radio-4.06.00.12_7.img when I had installed the CyanogenMod-5 5.0.8-N1, this time, I just have to upgrade to the new CyanogenMod-6 6.0.0-RC1.


So Cyanogen's instructions to upgrade are :

- Upgrading?
1. Do a Nandroid Backup!
2. Install the CyanogenMod-6 V6.0.0-N1-RC1 - 07/11/2010 ROM (your Google apps will be backed up automatically)

I add a 3rd step to Cyanogen's instructions to install the most up to date version of Google apps :
3. Optionally install the FRF91-HDPI Google Addon as CyanongenMod 5.0.8 installs EPF30+ Google Addon

The detailed instructions to follow are the same as for Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions to get the CyanogenMod-6 V6.0.0-N1-RC1 ROM update-cm-6.0.0-N1-RC1-signed.zip installed, skipping the WIPE steps 12) and 13) as it is not a first install and as Cyanogen doesn't require a WIPE in it's instructions.

Then I do again step 15) to install the FRF91-HDPI Google Addon gapps-hdpi-FRF91-signed.zip and I finish by a power down on step 17) instead of a reboot.

On step 18) everything started as usual, but the boot time was longer.


First surprise, the screen looks like my personalized screen instead of the new Froyo screen. Then my Gmail account was unavailable, and it was impossible to register a new one, making any synchronization impossible.

I then have to perform a factory reset to solve the problem. Everything works well now. But it suggests Cyanogen's instructions need another step to perform some kind of wipe.


The new CyanogenMod-6 comes with new wallpapers.

Nexus One - how to upgrade to CyanogenMod-5 [stable V5.0.8 (06/19/2010)] - instructions

The new 5.0.8 CyanogenMod has been released : CyanogenMod-5 for Nexus One: Kang Central Station V5.0.8 (06/19/2010) ([ROM] CyanogenMod-5: Kang Central Station (STABLE) [06/19/2010 / 5.0.8]).

Here are the detailed instructions to install it.

As the Nexus One's radio image has to be flashed to the Froyo's one, the instructions to follow are the ones Cyanogen gives for a first install, starting from step 2 with a wipe on step 4 :
- First time flashing CM to your Nexus (or coming from another ROM)?
1. Unlock your device and install Clockwork Recovery or Amon_RA's recovery image
2. Do a Nandroid backup!
3. Update your radio if necessary
4. WIPE
5. Install the ROM
5. Optionally install the Google Addon

If it's the first time flashing your Nexus, start from step 1 !! Directions can be found in the post Nexus One - CyanogenMod For Nexus One V5.0.5.3 (03/23/2010).

It may be useful to read the full process here How to Root Your Nexus One as well as other resources I have used for the initial root of my Nexus
Nexus One - CyanogenMod For Nexus One V5.0.5.3 (03/23/2010). Detailed instructions on the Cyanogen firmware upgrade process can also be found in my other post
Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions.


So let's start :
  1. first, prepare everything that is needed. Download all the images : CyanogenMod 5.0.8-N1 latest version, EPF30+ Google Addon and FRF50 Radio Firmware
  2. check the MD5 checksum of the CyanogenMod 5.0.8-N1 and FRF50 Radio Firmware files with a md5 the file to check on the command line
  3. connect your Nexus to your computer and mount it turning on USB storage mode, then copy the CyanogenMod 5.0.8-N1 and EPF30+ Google Addon files to the root of your SDcard but leave the FRF50 Radio Firmware on your computer as it will be flashed using a “fastboot flash radio the radio .img file” command from your computer's command line
  4. ensure the fastboot utility is in your PATH. The fastboot utility is not in the standard Android SDK on Mac but it can be found in the SuperBoot image which contains a fastboot version for Mac, Linux and Windows. Choose the one that pertains to your platform and put it in the android/tools directory, renaming it simply as fastboot
  5. proceed with step 2 : the Nandroid backup. Follow detailed instructions from step 5 to step 11 of the post Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions
  6. at then end of step 11, on screen "android system recovery", use the track ball to choose power off item (the last one), then press the track ball to select the option, and press the track ball a second time on the question to confirm the power off
  7. let's proceed with step 3 : update your radio. The following is based on instructions from How to Root Your Nexus One
  8. Boot the phone while holding down the VOLUMEDOWN-key. The screens turns white with 3 green Androids skating at the bottom of the screen. FASTBOOT is hilighted in blue. Press power button to enter fastboot mode.
  9. on your computer, open a command line shell. Navigate to the directory where the radio-4.06.00.12_7.img radio image has been stored. Then enter the command ./fastboot flash radio radio-4.06.00.12_7.img. The fastboot command starts by sending the radio image and display a status sending 'radio' (26112 KB)... OKAY, then writes the radio image ans display a status writing 'radio'... OKAY.
  10. back on your Nexus, select POWER DOWN item on the FASTBOOT USB screen using VOL DOWN key, then press power button.
  11. time to proceed with step 4 : WIPE. Reboot in RECOVERY mode by pressing power button while holding down the VOLUMEDOWN-key. The screens turns white with 3 green Androids skating at the bottom of the screen. FASTBOOT is hilighted in blue. Press VOL DOWN key to hilight RECOVERY, then press power button. The Nexus boot screen (the 4 colors cross) appears followed by the Cyan "Android system recovery" screen
  12. Use the trackball to hilight the "Wipe" item then press the trackball. On the "Choose wipe item" screen, wipe everything as stated on step 6 Wipe of How to Root Your Nexus One.
    • select the first open and press the scrollball
    • press the scrollball again to confirm
    • then repeat for all items on the Wipe page
    In the future, wiping this thoroughly won’t likely be needed, but this time, you’ll want to wipe really well.
    Press the Down-volume button to return to the prior menu.
  13. it's time to proceed with step 5 : install the ROM. Back to the "Android system recovery" cyan screen, use the trackball to select item "Flash zip from sdcard", then press the trackball.
  14. the screen "Choose update ZIP file" shows the 2 zip files update-cm-5.0.8-N1-signed.zip and gapps-passion-EPF30-signed.zip that were written on the SDcard at the beginning of the process. Select the "update-cm-5.0.8-N1-signed.zip" then press the trackball to install it, pressing the trackball another time to confirm.
  15. continue with step 5 again : optionally install the Google Addon.perform the same steps another time to install the gapps-passion-EPF30-signed.zip that contains Google's apps.
  16. Back to the "Android system recovery" cyan screen, use the trackball to select item "Power off", then press the trackball to confirm.
  17. That's all Folks !! Reboot your Nexus and enjoy ;-)

Nexus One - CyanogenMod 5.0.6 and 3G spotty issue - seems a kind of solution is about to be found

According to the thread 3G Connectivity Issue Fix? I think I found a solution using build.prop on the CyanogenMod forum, it seems a kind of solution to the Spotty 3G part 2 issue is about to appear.

It's not clear yet if it solves completely the 3G issue or only in part or if it is just a workaround, but it seems to improve the situation. And it's better than nothing considering Google had already said « engineering improvements » had been given an end : look for post from Ry Guy (Google employee) by 4/20/10.

By the way, some of the posts head to what seems to be very serious resources about 3G and mobile networks : Vodafone 3G vs Telecom XT on GeekZone forum.

Nexus One - disponible en mai en France - alors, l'acheter ou pas ?

Compte-tenu des nombreux échos négatifs dont le Nexus One a souffert, on peut se demander à l'occasion de la sortie du Nexus si c'est opportun d'en acheter un, ou s'il vaut mieux plutôt s'orienter vers un des autres modèles de même niveau : HTC Desire, HTC Incredible (lorsqu'il sera disponible), Sony Xperia 10, ...
Faites-vous votre opinion en lisant les commentaires de l'article Le Nexus One en mai chez SFR ! dans le Journal du Geek.

Nexus One - is Google starting to put an end to the whole "Nexus One experiment"

Recent moves on the Nexus One horizon makes one wonder if Google isn't starting to put an end to the whole « Nexus One Experiment » :

1) The 4/21/2010 Ry Guy post on the spotty 3G part 2 thread saying Google will no longer investigate the 3G issue


2) The 4/26/2010 news and updates designating the HTC Incredible as the next step after the Nexus One and announcing the Nexus One availability by april 30th in Europe when the HTC Desire — which doesn't seem to suffer from the same issues the Nexus One has — is already available from different mobile phone providers and resellers in Europe.



3) Is there another superphone Google wants to sell in it's online store after the Nexus One ?

Nexus One - a week after the CyanogenMod 5.0.6 upgrade

A week after the upgrade to CyanogenMod 5.0.6 just want to add that the result is quite good :
  • the Nexus works well for me, and by that I just say that the CM 5.0.6 upgrade doesn't seem to broke anything ; the Nexus is still faster than before installing the CM5 ; others have been experiment some issues, so don't forget to have a look at CyanogenMod issues
  • the « 3G issue » is still not solved, but the CM5 greatly improves the situation as the N1 jumps far more frequently from 3G to HSPDA with faster page downloads ; it's also a kind of solution : when the N1 stay for too long stuck on « 3G » with nothing else happening, it's time to activate Airplane mode just to reset the chip, then go back to connected mode (de-activate Airplane mode) and refresh the page the N1 stay stuck on before
  • the « screen becoming crazy issue » is still not solved : perhaps it becomes less frequent, but I'm not confident at all in that as I still have the problem after playing with the N1 for some time
  • I want to activate « tethering » with Mac OSX 10.6.3 but I haven't succeed : I certainly have missed something, as it seem's working for others, so more to come on that topic

Nexus One - how to upgrade to CyanogenMod-5 [stable 5.0.6 version of 04/15/2010] - detailled instructions

I just upgraded my Nexus One to CyanogenMod-5: Kang Central Station (STABLE) [04/15/2010 / 5.0.6].

As it is just a CyanogenMod-5 upgrade from 5.0.5.3-N1 to 5.0.6-N1, only the following steps are required :
  1. download the Cyanogen 5.0.6-N1 (the latest stable CyanogenMod for the Nexus One) from Cyanogenmod For Nexus One V5.0.6 (04/15/2010) : update-cm-5.0.6-N1-signed.zip
  2. check the MD5 sum :
    md5 update-cm-5.0.6-N1-signed.zip
    and check the checksum
    MD5 (update-cm-5.0.6-N1-signed.zip) = 43835d679958294befa16af78bf7311b
    against the one of the forum MD5Sum: 43835d679958294befa16af78bf7311b
  3. connect the Nexus One to the computer and mount the Nexus One in the Mac
  4. copy the Cyanogen 5.0.6-N1 (the update-cm-5.0.6-N1-signed.zip) file to the root of the Nexus One SD-card. Wait a few seconds in order to be sure everything is copied to the SDcard. Unmount the Nexus One on your computer.
  5. Reboot the Nexus One in bootloader mode : hold down the trackball while you press the power button. Ensure to maintain the trackball hold down until the screens turns to a white screen with 3 green android skating at the bottom of the screen. Ensure that the Nexus One stay connected to the computer via the USB cable.
  6. on the screen, the BOOTLOADER should be highlighted with blue. press power button
  7. on the new screen, scroll down with the Volume down button to highlight the RECOVERY option. Press the power button.
  8. the Nexus One reboots and after a few seconds, the screen title with "Android system recovery" appears, with the "Build : RA-nexus-v1.7.0" at the bottom of the screen. The screen should be in cyan instead of green if the Nexus One has already been rooted
  9. scroll down with the trackball to the "Backup/Restore" menu and press the trackball
  10. on the new screen "Choose backup/restore item" choose the option "Nand Backup" (the first one) by scrolling down the trackball and press the trackball to select it. The question "Create Nandroid backup?" appears at the bottom of the screen, so press the trackball to confirm as it is stated
  11. The backup starts, it takes a few seconds to complete. At the end of the backup, the cyan screen is restored. Press Volume down button to return to the previous screen "Android system recovery".
  12. FIRST INSTALL ONLY : scroll down to the "Wipe" item using the trackball and press the trackball to select the option
  13. FIRST INSTALL ONLY : in the new screen "Choose wipe item", using the trackball, select every wipe item one after the other and perform the wipe pressing the trackball. When every wipe has been performed, return the the previous screen using Volume Down button.
  14. back to the Android system recovery screen, scroll down to the Flash zip from sdcard item using the trackball. Press the trackball to select
  15. on the new screen "Choose update ZIP file", use the trackball to select the right ZIP file to flash. Here, there should be only one zip file available to flash : update-cm-5.0.6-N1-signed.zip. then press the trackball to start the flashing. Press the trackball again to confirm flashing on the question "Install : update-cm-5.0.6-N1-signed.zip ?" that appears at the bottom of the screen. The ROM flashing starts and many messages appears on the screen.
  16. after some time, the message "Install from sdcard complete" appears and you're back to the cyan screen "Android system recovery" with the item "Reboot system now" selected by default
  17. just select the default option by pressing the trackball down. The Nexus One reboots.
  18. after the Nexus One has boot the normal way, just to be sure, check the "Mod version" value in the "Setting" then "About Phone" : the value should be "CyanogenMod-5.0.6-N1"

I adapted the instructions from Step by Step Guide on How to Install Cyanogen Mod ROM on your Nexus One! to perform the upgrade.

Nexus One - CyanogenMod For Nexus One V5.0.5.3 (03/23/2010)

I have just installed CyanogenMod For Nexus One V5.0.5.3 (03/23/2010). It takes me quite some time because I missed some important points, the most important one being to root my Nexus using superboot.

Cyanogen's advise is to download everything that will be necessary and to check the md5 checksum.

Then, the first step is to unlock the bootloader using fastboot. fastboot can't be found in the android sdk but it can be found in the superboot archive contents.

During the whole process, I've found useful instructions in those locations :
Everything seems to work well. More feedback soon.

Nexus One - review from a Finn developer - there still are some bugs

In the post A Month of Nexus One, Heikki Toivonen lists some the bugs he has encountered on the Nexus One : "I’ve encountered some annoying bugs as well. During my first week the phone got into a state where tapping the messaging icon always launched the browser. The only way I could recover was to reboot. This hasn’t happened since. Far more common problem is the soft keyboard not registering taps, or thinking I pressed one of the four buttons at the bottom (back, menu, home or search, with accompanied vibration feedback). Switching back and forth between apps fixes this eventually. I also seem to have situations when I don’t seem to get any GPS information. Some people have reported that this might require a reboot, but I haven’t been trying persistently enough to confirm if this is the only cure.".

I also encountered some problems with the four soft key at the bottom, where they don't seem to work at all, or when they seem to trigger the same action, or even when touching the screen in the middle triggers one of the four soft key button ... In those situations, the best thing has been to reboot the Nexus. It seems this happens more often when the phone has been up for some time, or when there has been some weakness in the network (I use the Nexus during my commuting time and there are a lot of places where there is no or poor quality network that make the Nexus to frequently switch between Edge and 3G).

Nexus One - activate ADB connection mode

By default, the Nexus One is not visible from ADB while executing the adb devices command from the terminal.

$ adb devices

Instead, it can be is mounted like a USB key.

To access the Nexus One using ADB commands, the USB debugging mode has to be checked in the Android global setting (Menu button, then Settings item, then Applications item, then Development item, then check USB debugging mode).
