need to downgrade from CM6 to Stock 2.2 - Nexus One Q&A, Help & Troubleshooting

I have sold my phone and I am currently using CM6 RC3
The buyer want me to install the stock 2.2
can someone please provide me with the Download to stock 2.2, and the instructions, Just flash over cm6?
Thanks

You could download the FRF91 system image (link in my signature) and flash it using fastboot...
1. reboot into bootloader
2. extract the downloaded zip
3. fastboot flash userdata userdata.img
4. fastboot flash system system.img
5. fastboot flash boot boot.img
6. fastboot flash recovery recovery.img
Your radio and hboot can remain unchanged (they are stock anyways)

thanks alot of your help:
I am not fimilar with using fastboot
is there a way to use recovery and flash from zip file, that is how I have been trying out different roms

I think ROM Manager has the stock rom available. That would be the easiest way.

[Q] Is this the correct way to upgrade G1

I want to upgrade a US T-Mobile G1 to 2.1. Is the following procedure correct? (Don't need to backup.)
In bootloader flash RC29 DREAIMG.nbh. Reboot.
Type telnetd, install Android Telnet Client and root.
Install recovery-RA-dream-v1.7.0-cyan.img using Telnet Client.
In recovery flash G1-radio-2_22_23_02.zip. Reboot.
In recovery flash spl_1_33_2003.zip. Reboot.
In recovery flash FR-recovery-v1.5.3-CustomMTD_S.zip. Reboot.
In recovery flash signed-SuperE103.zip then flash gapps-mdpi-FRF91-3-signed.zip then flash FR-boot-v1.5.3-CustomMTD_S.zip. Reboot.
Your way will work but I recommend a minor change iif you are using the rc29 method of rooting:
In bootloader flash RC29 DREAIMG.nbh. Reboot.
Type telnetd, install Android Telnet Client and root.
Install recovery-RA-dream-v1.7.0-cyan.img using Telnet Client.
In recovery flash spl_1_33_2003.zip. Reboot. (Will return to recovery)
boot fastboot and flash the 2.x radio (info on my 1.33.2003 post.. and the *.img file is in the g1boot.zip)
while in fastboot wipe so custom mtd works 'fastboot erase system -w' and 'fastboot erase boot'
In recovery flash FR-recovery-v1.5.3-CustomMTD_S.zip. Reboot.
In recovery flash signed-SuperE103.zip then flash gapps-mdpi-FRF91-3-signed.zip then flash FR-boot-v1.5.3-CustomMTD_S.zip. Reboot.
I'm not 100% sure of that gapps package.. just check the super-e page if its correct
Edit: If you don't want to downgrade first look at:

Thanks for the links. What is the advantage of installing radio via fastboot instead of recovery?

Rather than re-iterate see my post here: http://forum.cyanogenmod.com/topic/...e-via-fastboot/page__view__findpost__p__44790
In short it should be of similar difficulty for you the user and it has slightly less risk (not that there was much risk in flashing a 2.x over a 1.x one in recovery)..
For many scenarios that could brick however: if you flash via fastboot you will likely continue to be able to access fastboot after the flash; thus able to fix the phone.. while if you flash via recovery you get stuck in "boot mode 3" unable to boot anything without JTAG.
Thanks for explaining and writing the exploit guide. Will try!

[q] urgent help! About to do something risky!

I'm flashing the dev phone stock rom for the g1 on a canadian ebi1 rogers dream. I've changed my radio to g1 hence i went from ebi1 to ebi0. I have a question though.. Would these be the steps to flash it?
At http://developer.htc.com/
1) download the system image (signed-dream_devphone_userdebug-img-14721 )
2) unzip the zip file on your computer
2) make sure you have a 2.22.* radio less than 2.22.27.08 (2.22.19.26I is the one this rom shipped with)
3) run 'fastboot erase system -w'
4) using the files in that zip run 'fastboot flash boot boot.img' and 'fastboot flash system system.img'
5) boot the phone, you will be on the official google rom
EDIT: I've flashed it succesfully.. Turns out I didn't like the rom.. flashing another..

Flashing 5.0.1

I downloaded the flashable zip from https://www.androidfilehost.com/?fid=95851846488293411
I use WugToolKit with TWRP, Unlocked and Decrypted. Stock ROM
I'm confused as to how I should flash this, I've read I should just click flash zip in the toolkit and let it finish and done. Also that I could download the file to my phone and use TWRP to flash straight to the phone. Some say backup and some say don't. Also some threads say I need to flash back to factory image, tho this flashable zip should be a factory image of 5.0.1.
Any help will be appreciated. Thank you.

Apparently the new update OTA or zip will update blocks instead of files so from my understanding, even the slightest change from stock will cause this ZIP to fail when flashing. I'm rooted, decrypted, and changed mixer_paths.xml and as expected the flash failed in TWRP and adb sideload so I'm backing up via Titanium and flashing the 5.0.1 stock. I'll decrypt/root/restore after the flash.
Here are the steps I took to flash the factory image and not lose my settings:
Flash bootloader and radio:
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.05.img
fastboot flash radio radio-shamu-d4.0-9625-02.55.04.img
After flashing the bootloader/radio, you need to reboot the bootloader as shown below, don't skip this step!
fastboot reboot-bootloader
I then unzipped this file: image-shamu-lrx22c.zip
Now you can move on to the rest of the files
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
Finally, just reboot your device, and Android should start up.
fastboot reboot
After the phone restarted I then used CF-Auto-Root to re-root my phone. I did not lose any of my settings or installed apps. HTH...
So if I am stock but rooted I cannot sideload the OTA?
I keep getting status 7 error when trying to sideload with ADB using the update OTA.
It actual unzips and installs about 50% and then I get the Status 7 Error

Rooting causes a change to the system partition, so no, you can't sideload the OTA anymore. (not since Lollipop)

No, he used fastboot. Be wary of toolkits. They can do damage that a novice wont be able to fix.

Jeezus! perfect!
Thats similar to what I did.
Only thing to do if you are already decrypted is to download this boot file, rename it to boot.img and flash it instead of the one included in the google zip package.

I had to manually flash each file separately. For some reason when the flash.bat file was running it kept reporting that the system.img file was too big. Not had that before.

yeah - since 5.0, the flash-all.bat isn't working for a lot of users.

From what I understand, if you flash cache.img, you will go back to stock and lose all of your settings.
Awesome man, worked perfect, you sir rock!

The only thing that I'd add, to avoid any confusion, is that the factory image can be downloaded from:

Curious as to why so many steps?
All i did was flash the radio and system images. Went to 5.0.1 just fine, all settings/data retained.
Didn't flash bootloader, kept unlocked during process, only had to re-root.
Having an issue while flashing system.img file. I flashed radio, and flashed system.img then flashed cf-auto-root. On first start up I was having issues with my radio. LTE was not connecting to T Mobile. So I Nandroid back to stock. Then of course I noticed this didnt change my radio back to stock. Starting everything over, I reflashed radio, reboot bootloader, Flash system.img, reboot bootloader, then fash autoroot. Restart device. Radio was flashed and I had root, but stuck on 5.0 Tried to reflash system.img and I am getting error. "access denied" when flashing. I have read this is an issue with mounting the drive, I have even tried to do this in fast boot but I am coming up with nothing. Any help on this will be greatly appreciated.

[Q] How to flash 5.1 image?

Current: Unlocked, Rooted, TWRP, Custom Rom 5.0.1, Custom Kernel, Encrypted
Goal: Unlocked, Rooted, TWRP, Factory 5.1.0, Custom Kernel, Decrypted
How do I go from my current state to my goal?
Would the following steps be correct and shortest?
1) Flash factory image - Flash All
http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008
2) Disable encryption - Flash kernel, disable + wipe
http://forum.xda-developers.com/nexus-6/development/disable-forced-encryption-gain-root-t2946715
3) Install Root - SuperSU
http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
4) Install TWRP
http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
5) Install Custom Kernel
Is step 2 in the correct order? Do I perform the install and disable to eliminate all traces of decryption?
Step 5, do I flash the kernel via TWRP or use the kernel's app from the Google Store?
Bump
I was Stock 5.01. except rooted and decrypted.
Copied SuperSU.zip to my Nexus 6.
had all the .img files extracted and in the same folder as my fastboot.exe from the Android SDK (make sure you are at the latest).
Boot to bootloader.
fastboot flash bootloader bootloader-shamu-moto-apq8084-71.08.img
fastboot reboot-bootloader
fastboot flash radio radio-shamu-d4.0-9625-02.95.img
fastboot reboot-bootloader
Using a decrypted flagged 5.1 boot.img
fastboot flash boot de-cryptedboot.img
fastboot flash system system.img
fastboot flash cache cache.img
I reflashed twrp as well...couldn't remember if I had left it on or had flash to stock recovery after rooting.
fastboot flash recovery twrp-2.8.5.0.img
When that finished flashing I used the volume keys to move to "boot recovery" and pressed power.
Team Win Recovery came up and I installed SuperSU.zip
Rebooted...done. 5.1, unencrypted, rooted and kept all my data.
Where did you get the decrypted boot img from?
From this thread.
http://forum.xda-developers.com/showthread.php?t=2946715
does the ota zip file contain all the .img files.............
it looks like it does, but there not all named in the normal fashion..........
can this be clarified.......
what files are what?
They are all there. Bootloader and the radio are in the main zip file and the rest are in the zip that is inside the main zip file. Extract both zip files.

after seeing this post I realize your talking about the factory image (tgz) and not the OTA zip.........
I have now downloaded the image but I am sure this post was referring to the 5.1 ota zip.......

Need the Stock Recovery image

I want to have the img of the STOCK recovery so i can have the OTA update installed. Tried to flash the recovery.img in L78032_CN_ZUI_11.5.223_ST_200401_qpst.zip directly with fastboot but no help. Does anyone can help? Great thanks!
