[Guide] How to flash back to Stock Rom - chacha. Please Sticky This !

---

Alot of the guides floating around showing how to flash back to stock rom is incomplete ( missing a few steps ) and will result in boot loop most of the time. the correct procedure is :

Part 1 : Setting up Fastboot.

1. Make sure you have java installed, if not get it from here : http://java.com/ and install it.

2. Download the Android SDK manager from here : http://developer.android.com/sdk/index.html ( get the exe download )

3. Install SDK manager, then run the android SDK manager.

4. Once launched it will show you available updates, choose ONLY these two "Android SDK Platform Tools and Android SDK Tools" and update them.

5. After update is complete close the sdk manager and go to the SDK manager platform-tools folder, normal path is : ( C:\Program Files\Android\android-sdk\platform-tools )

6. Copy the following 3 files from this folder : "adb.exe" , "AdbWinApi.dll" and "fastboot.exe"

7. go to your c drive ( c:\ ) and make a new directory called "fastboottools"

8. copy the 3 files above into your fastboottools folder.

9. so now your should have a folder like this : "c:\Fastboottools" with the following 3 files in it "adb.exe" , "AdbWinApi.dll" and "fastboot.exe".

That is it, Fastboot tools is setup. Proceed to next guide.

Part 2 : Flashing guide.

1. download the ROM from here:
ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35. 3033h_7.51.35.19_release_228383_signed.zip

or here ( mirror link ) : ruu_chacha_htc_asia_wwe_1.57.707.2_radio_47.23.35. 3033h_7.51.35.19_release_228383_signed.zip

2. Extract and copy the system.img AND boot.img to the same directory as your fastboot tools "C:/fastboottools" ( make sure to copy both files )

3. Enter the fastboot mode on your phone by pressing volume down + power button after the device has been turned off.

4. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC

5. Using fastboot tools, open the Command prompt and navigate to "C:\fastboottools" then run this command on cmd: "fastboot flash system system.img"

6. Dont reboot, Using fastboot tools, run this command on cmd: "fastboot flash boot boot.img"

( The two commands in step 5 and 6 are different, make sure to type each one correctly and to do them straight after each other )


7. Reboot phone. let it boot up, you will still get bootloop or error message.

8. Take out the battery.

9. Boot back into bootloader ( Volume down + power ).

10. Now choose recovery.

11. Phone should now reboot itself and bam, all should now work fine.

after trying EVERYTHING else, this is the method that worked for me, i tried to cover every step possible ( alot of the other guides skipped few steps and that is where i got problems ).

hope this helps.

( PLEASE BE AWARE : This will remove recovery and root. if you flash back to stock rom using this method you will have to root your phone again. It will still be unlocked, just recovery and root will be removed. to re add recovery and root check part 3 below. )

Part 3 : Add recovery and root access back after installing stock rom.

1. Download the following 2 files, you will need them :
PH06IMG.zip
su-2.3.6.1-ef-signed.zip

2. Extract PH06img.zip to your "c:\fastboottools" directory. it will add the "recovery.img" file to fastboot.

3. Copy the file su-2.3.6.1-ef-signed.zip to your phones SD card, dont change the name, keep it standard, just put it in the root directory of your SD card.

4. go to the settings on your phone "Settings -> Power -> and Uncheck Fast boot" ( This is important, make sure fastboot is unchecked.

5. Take out your battery, put battery back in and boot into bootloader ( hold down volumedown + power )

6. Choose fastboot on the phone by pressing power button, and then connect your phone to your PC

7. Go to the Fastboottools directory "c:\fastboottools", Hold CTRL+Shift and right click in that Folder and open Command Prompt.

8. type inside command prompt : "fastboot flash recovery recovery.img" and let it finnish, takes less than a minute.

9. reboot your phone, but reboot it back into bootloader ( hold down volumedown + power )

10. Now using volume keys choose "recovery" and press "enter" ( not power button, rather use enter button in recovery else you sometimes get a "hat like" picture on the screen )you should now see the recovery options.

11. find the "install zipd from sd card" option and press enter, then choose su-2.3.6.1-ef-signed.zip and confirm to flash it.

12. once flashed reboot the phone and you will now have recovery and root access back again.

it is recommended you update superuser to newer version and also install busybox.

Now that you have recovery installed you can also flash custom roms again.

I STRONLGY recommend once you reach this step that you make a backup of your rom via the bootloader recovery menu, that way you dont have to go through all this pain again next time.

The End !!!

feel free to post any problems you encounter below.

stuck on bootloop at step 10

---

I've attempted the recovery and get as far as step 10, but unfortunately
"still suffer the bootloop.
what am I supposed to do in the recovery step to get it working fine!
do i load the update.zip?

please reply if availale... am stuck on bootloop

ty

bootloop ussualy happens when you dont clear your cache properly before flashing.

Make sure to clear ALL cache, and also make sure to follow the steps exactly as they are posted, even if it looks like you can skip a step DON'T. do each step as posted, and clear all cache when you are told to. then you wont get boot loops.

Hi,
I bought HTC chacha locally at a online retailer. Its not tied to any sim/operator. However I am stuck at android version 2.3.3. (firmware version 1.20.720.1). If I try to run the (ota)software update, the phone says no updates available.

I really need to unlock the boot loader. However if I try the htcdev.com, the RUU utility says that the please update to 1.57.XX and then try unlocking the bootloader. I am really stuck here.

My question is can I try the steps mentioned above in this post to get the firmware update, with a locked bootloader?
Any other suggestions to update my firmware to the latest 1.57.XX?

--Thanks in Advance..

htc status restore factory 2.3.3

---

No, I didn't make a real backup! I thought titanium backup would cover that, it didn't, so I have no backup of the stock stuff.
I have a HTC Status (aka chacha) US ver with att. I unlocked the boot loader by htc's site, worked fine. Then I rooted it with cmw, worked great.
Recently the ota 2.3.5 update (48mb) became available. I downloaded it and tried to install it, it failed with checksum. I know it is the cmw mod. How can I get the stock load 2.3.3 back onto my htc status? The above directions mention the "asia" load. Are the files mentioned generic for all phones with the exception of the cid?

p.s. It would be great if someone out there had the stock 2.3.3 recovery file for the status! That would be easier to load than the sdk stuff.

update : both ruu files listed above show to be corrupt when unzipping.
Update: I installed a newer zip utility than the stock win xp one and it unzipped without any trouble. Moving on to the next step.
Update: all went well, except the "english" option, I chose english singapore. Installed cwm and rooted again. updated to 2.3.5. Thanks for the info above.

thank you!

Does the phone need an unlocked bootloader?
Can the be a way to debrand the firmware? Is the firmware attached the latest generic one?

Thanks

A new ota update was available (1.57.707.3) but it won't install, it says the current rom seems to be altered and it refuses to install. So I went to htc.com/support and found the status page and downloaded the latest installer for 2.14.502.2 rom image. It fails with "security fail" under ruu in the phones bootloader screen.
The installer on the pc say's I must get the correct rom installer for my phone. I think it might have something to do with the asia chacha system and boot.img 2.3.3 stuff I installed.
Current software is android 2.3.5 and software 1.57.707.2
Is there anyway to get rid of cwm or force the new rom to install over the old?

Thanks man
