Where to find image for stock 4.0.4
there is video by techfanatic in some other thread , . i want to ask is it the same thing as in my case ?
can i follow it ?
please confirm

SEARCH!!! If you can't find the 4.0.4 image on the Google site that's your fault but we're not going to spoon feed you
For reference, though, do NOT use that video guide as you do not have to go anywhere near Odin to go back to ICS. You DO have to unlock the bootloader, though, so backup your data before doing so as flashing a stock image wipes everything

thanks for your concern
can you please tellme why this video is not appropriate for me ?
i preassume i have the same case as demonstrated in the video
i want to go back to 4.0.4
i wil backup my data
1. Backup your data
2. Download the 4.0.4 factory image from Google
3. Flash it following the guide I linked to earlier
You didn't answer why on earth you wanna go back to 4.0.4 though. Go to 4.1.2 if you have to but why not stick to 4.2.1?

The point is it's not mine but my friend's gnex. He accidently updated the device OTA from 4.0.4 to 4.1.1
He was quite conformtable with the 4.0.4. Thus he requested me to flash the device back to 4.0.4 for him.
I have read the guide in link provided by you
The device is unrooted and not customized at all at any time.
So what i have to do is to unlock the bootloader and then follow the tutorial as given.
Please confirm. Am i right or am i missing something over there ?
Thanks
You're right, but just tell your friend to stick with 4.1. There's very little difference
i m not sure its a problem or not but i cant update my htc one x either through automatic update or manual....my "about" option shows me this screen plz tell its with everyone or i have this problem and any solution???

it not a problem , its just your phone is rooted so this rom you running doesnt have that option , you will have to download a rom you need like 4.2.2 with sense 5 manually , and flash it from the recovery if you know what i mean, :good: remember to thanks

yes, you need to find out your cid and main version using this command "fastboot getvar all", then you need to flash the stock recovery and stock odexed rom, relock bootloader and then you should be able to receive OTAs... look around for guides

Basically the phone will get update via OTA if it's on stock rom and stock recovery. Seem yours is not on stock rom.
My question is: how do you know there is an update when your phone is having trouble with "check for update" function?
Aldo, pls post the screenshot of "Software information" and Kernel information (click "More" inside Software information).

I asked just to make sure your phone is not on 4.2.2 and that you want ota 4.3 update.
Well, by the screenshot, you're on custom rom.
Now if you want stock 4.2.2 with sense 5 please do as follow:
1. Flash stock rom 4.2.2 (odexed) or nandroid
- Steps:
+ Identify your cid, and download stock rom or nandroid backup
+ Unlock bootloader (if locked)
+ Flash custom recovery (twrp, cwm..) and copy rom to phone memory (sd card)
+ Boot into recovery: Either flash stock rom or restore from nandroid backup file (remember to follow rom instruction carefully)
+ Reboot and there you go.
2. In case there is no 4.2.2 stock rom/nandroid but 4.1.1 only:
- Do same as above steps and your phone is now at stock rom 4.1.1
- Flash stock recovery (required)
- Reboot and check for OTA 4.2.2 update
- After OTA update, perform nandroid backup and save for future usage.
Report the result.
EDITTED:
Please make sure to backup your phone's data before proceeding as you might lost during rom flashing!

Sorry being quite busy with work these days.
Ok, you have downloaded nandroid file, now find stock recovery to download and follow the steps:
- Copy nandroid file to phone storage

- Boot phone into recovery, select install from zip file, browse to the nandroid backup file and proceed.
- Wipe all if boot loop.
- Flash stock recovery
- Reboot phone
Now your phone is in stock status which is ready for ota update. Go "Check for updates" and see..

How does one backup the existing stock recovery, before installing Clockwork or whatever other custom recovery you have?
I'm assuming you can't use Download mode, because that's just one direction, from computer to cell.
Could you maybe use a program like Root Explorer to copy the stock files to the SD card?
If this is possible, how would you package it into a tar suitable for Odin later on?
Thanks guys!

I thought that was only for rooting your cell, not making a backup of the current recovery code.

So if I extract recovery.img from Samsung's tar.md5 package, can I just use Odin to load the .img into the cell, or do I need to add a script to it?
Hi,
I am just writing these steps to help those who want to downgrade from KK to JB due to any reason. Please use these steps at your own risk.
Some Background:
Recently I updated my Razr M to KK, it was Locked and Unrooted, but with the help of Twelroot and Motopocalypse I rooted and unlocked the BL.
Now somehow I didn't like the KK and wanted to go back to JB 4.1.2 because I was now having unlocked BL and rooted phone so it was easy but need to follow some steps to successfully downgrade to JB. So an unlocked BL and rooted with KK is must.
Prerequisite:
USB drivers for Razr M must be installed before proceeding.
Steps:
1. download the firmware file [Android 4.1.2
Blur_Version.98.30.1.XT907.Verizon.en.US] from http://sbf.droid-developers.org/phone.php?device=8
2. extract the above archive and replace the XML file with the one in attachment.
3. put the phone into fastboot mode and flash the firmware with RSD Lite (attached)
4. reboot and now you have JB 4.1.2
If you want to install root application again and also want to flash custom recovery then please follow the Post#5 [ATTACK] (thanks ATTACK)
Note : for custom recovery you will need the fastboot.exe if you don't have it then install minimal_adb_fastboot_v1.1.3_setup.exe(attached).
Put the phone in fastboot mode, copy the recovery to c:\ and execute the below command :
fastboot flash recovery [Path to recovery image]
If it help you then don't forget to press Thanks button !
Forgive my ignorance but this won't downgrade the kernel will it? I'm hoping it's possible to go from the newest OTA to the stable CM11 but I'm guessing this is new kernel JB. Either way thanks if I can't go to stable CM11 I'll stick with rooted 4.1.2.
Once you have a unlocked bootloader, you do not need to use "root programs". All you need to do is flash a custom recovery via Mfastboot / fastboot then flash SuperSU / Superuser.
In dhacker29's folder there are 2 different recoveries.
"msm8960" is for 4.1.2
"KITKAT" is for 4.4.2

The steps are tested by my 2 times, and there shouldn't be any problem. Make sure you have installed the correct drivers.
Please ensure that your bootloader is unlocked and shows BL unlocked status code 3 on BL screen.
I was also able to successfully flash back to JB with House of Moto via fast boot and full data wipe. It would not work with Universal or Keep Data, had to do full data wipe. Just another alternative :good:

Thanks You Its a Success Downgrade From 4.4 stock > CM11 > Stock rom 4.1 Thank you so much !!!
For those undergoing the downgrade process in RSD Lite and it takes forever for it to finish and the system ends up without data/signal, you need to RSD Lite flash again in order to regain signal. I believe the flashing was sluggish due to the jump from 4.4.2 to 4.1.2 and the many changes that were reflashed.

We have a wiener!
Thank you so much for the guide. After a lot of trial and error (mostly error), I thought that I had bricked my lovely XT907. I finally restored KitKat by flashing the 4.4.2 firmware with the edited XML file (deleting lines with "Getvar", "var" and "oem" in them), then followed your guide to the letter and found myself with a perfectly functional phone once again. No more sticky fastboot loops or audio-related crashes for me!
Lovely guide - thanks again! :laugh:

I would like to restore my stock recovery on 1.56.720.6, im unable to find this one on xda, My other option is to extract it from the OTA but there is no link anywhere to download that, can someone help me with this?
EDITL downloaded from htcdev site its a 100mb file do I flash the whole thing using super tool? if so which option should I pick to flash or goto CWM and flash from zip?
does my bootloader need to be locked before I do this?
anyone?
Is that download actually firmware or the OTA update?... I think it's only source code? Did you download it and check in the .zip file what the actual contents are before you just go and flash random .zip files with your version number on it?
As for stock recovery, correct, I can't find that stock recovery either. Just like with the OTA update most guys that get it don't bother making backup and sharing before doing anything.

They don't specify on the HTC site but when I unzip it there is a .tar file inside it, so I assume its either the ota or kernel source which someone more experienced than me can tell me.
