Back to stock rom? Do i need unroot? - EVO 4G Q&A, Help & Troubleshooting

I have an evo 4g of Japan. The KDDI network. I've root it. I'm using the rom CM7. But now I want to go back to the original rom 2.3.3.
I had KDDI FW.Here: http://www.filefactory.com/file/cfd...15.00.03.04_NV_2.11_release_176711_signed.exe
Now what do I do with this exe file? Do I need to unroot ? Or I will install directly?

If you just want to go back to the stock rom, you do not need to unroot. However, if it's an exe file, it's likely an RUU, which WILL unroot you and return you to stock. If you just want to return to stock and keep root, you need to flash a stock rom zip file. I'm not sure about the Japan version, if you can use the regular roms or not.

You'll probably want to get DI18 image instead of DG27 and the follow the instructions in that thread.
Why do you want to go back to stock rom?
the best way to go back to stock is to download odin and here the tar file http://forum.xda-developers.com/showthread.php?t=794138
You probably also want the 512 .pit considering that is basically the formatting map for the rom, the kernal, and the modem.

How do I back up my stock recovery?

US Cellular has been promising Froyo for the CDMA Desire since October, and I'm tired of waiting so I'm going to root it and flash a Froyo ROM myself. I read through the unrEVOked documentation, and it mentions that if I want to install official updates in the future I need to restore the recovery image, but it doesn't tell me how to get it. How do I pull the stock recovery image from my phone so that I can flash it back on should I need to?
You can't actually backup a whole rom without rooting first. You need the custom recovery to do a nandroid backup which will back up the whole rom. If anything does go wrong or you need to reinstall then you can just use an RUU to do it. US Cellular doesn't have an RUU yet but you can use other CDMA RUU's.
So am I to understand that there is no way to back up the stock recovery, as I would have to overwrite the existing recovery just to do backups in the first place?
Yep, root access is needed to back the whole ROM up
To be honest, it's better with root anyway and a lot better when you install a custom rom.... from my experience anyway.

[Q] Bell Desire Z stok Rom

Hi
I'm desperately looking for any Bell mobility stock 1.34.666.5 or Over.
The camera button is not working so I sent my phone to repair but they send it back because I do not have the right rom that was provided with my phone. I was able to unroot and put back 1.34.666.1 (the only one that is available it seems) but the technical support told me that my phone shipped with 1.34.666.5 and that they can't do anything unless I'm putting back this rom.
I tried getting OTA updates for 1.34.666.1 but it's not available. Minimum rom # to get OTA updates have to be 1.34.666.5
I'm screwed.
Regards
I have a nandroid backup of the stock ROM...it's rooted though.
Will I be able to flash using Clockwork Recovery? I can manage to remove root after flashing, I think.
Yes, flashable via Clockwork.
I'll let you know when I have it uploaded.
...and it's up.

Some notes:
- I only included the system and boot portions of the nandroid backup due to privacy concerns
- As such, you should do a system and boot restore (after a full wipe, of course) under "Advanced Restore"
- As mentioned earlier, this is rooted (so you'll need to unroot)
Hope this helps. Let us know how it goes.
Good news, I have been able to return to stock 1.34.666.5. Thank you very much for your backup.
I was thinking going unrooted was to be easy but i'm a little bit stuck.
How can I unroot and put back stock bootloader without flashing a new rom.
If I have to flash a new rom, is there a way to build one based on the backup you provided?
I've look at software update and there's an OTA update available for my phone. I tried to install but because I do not have the right bootloader (I think that's the problem) I'm unable to do the OTA update.
Thanks.

That's good to hear. I'd recommend making your own nandroid backup immediately.
As for the bootloader, you're sure you flashed the ENG HBOOT during the rooting process? If that's the case, I'm not sure where you can find the stock HBOOT...
Yes, I installed the Eng HBoot.
I'm trying now renaming the OTA update.zip, put on the root of sdcard and make recovery to install that update but I got an error about getprop CID?? and the update failed...
Still looking for a solution.
How did you make out Tonkadan? I'm in the same boat. I heard that if you did apply this update that you would not be able to root your phone anymore.
I' still rooted. I'm unable to go back to stock. I'm using cyanogenmod 7 for now but would really want to go back to stock if somone have the official Bell rom over 1.34.666.5.
... Or any way to get OTA updates for RUU 1.34.666.1 that is available on shippedroms.com

[Q] how to unroot/flash to install sprint patches

I'm trying to revert a Sprint customers phone back to factory defaults so he can install the carrier patches and updates, is there a way to do this? would i need to unroot or just flash a stock rom?
just need to know where to start, any suggestions or advice would be greatly appreciated
Assuming it is rooted now, if you don't want it to be rooted, just flash a stock RUU, that will unroot and return you to stock. If you want it to stay rooted, just flash a stock rooted rom.
