[Guide] Return stock without latest RUU

Who should read this post?
You have updated your One X to a newer version via OTA, then you want to restore the software/ return stock but the latest RUU is not available. (boot to fastboot mode and type the following command "fastboot getvar version-main", This is the true version of your phone!)
You have some basic skills to flash things using "fastboot"
Those who want to back to stock and wait for the JB OTA.
Those with ICS hboot should works without any problem, someone had test it on JB hboot and works(updated in step 6, 7). but we need more testers.
The concept behind.
1. Fool the RUU to make it believe that it is flashing the latest ROM, but actually, we are flashing an older version.
2. after that, boot up the phone with older version of software, then OTA and update the phone to latest software.
How to do that?
0. backup all your stuff including those in SD, all your stuff in your phone will be lost. Then wipe all data (including SD) using your custom recovery. (important! Otherwise, you may not be able to receive OTA).
1. You have to download a "custom RUU" that can be found here.
http://db.tt/z8ajRTuH
Feel free to give a thanks to billd2439, he provide this working link to download the custom RUU.
Just go to #115 http://forum.xda-developers.com/showthread.php?p=35139501#post35139501 and give him a thanks
2. Download the ROM file, it should be in zip format. (You can also extract the rom file by running a RUU, just run the RUU, don't click anything and search the computer for "rom.zip") (In my case, I have an older version 1.29.708.15 rom extracted from RUU)
you may want to find RUU here http://www.htcruu.com
3. unzip the customRUU.zip to a folder, e.g. "customRUU"
4. unzip and extract "android-info.txt", "boot_signed.img" and "system.img" to a folder
5. open android-info.txt with "notepad" (notepad++ is highly recommended)
6. type the following command to get the information from your phone.
fastboot getvar all
you should pay attention to the following information
modelid:
cidnum:
mainver:
hbootpreupdate:
7. edit the value of "modelid", "cidnum", "mainver" and "hbootpreupdate" to match the information you get from step 6.
by doing this your will try to fool the RUU to belive that you are going to flash a newer version e.g (I have OTA my phone to 2.17.708.7, but now I want to fool the RUU with this old rom with a version number of 1.29.708.15, so I change the value to 2.17.708.7 )
Thanks ahmedaljaf for telling me to modify hbootpreupdate to makes JB downgrade works
8. save the file.
9. zip "android-info.txt", "boot_signed.img" and "system.img" and rename the zip to "rom.zip". (remember only zip the files, not the whole folder!)
10. place the "rom.zip" you just created to the "customRUU" folder
11. make sure your phone is still "unlock", remember to turn on USB Debugging, unplug the USB cable and reboot your phone, then goto fastboot mode and connect the USB cable.
(important, do the above to avoid error messages in RUU)
12. run the file "ARUWizard.exe" inside the folder "customRUU" (see the Attached Readme_Eng.pdf if the customRUU cannot display in correct language)
You can change the customRUU to English version by just delete or rename the language file "ARUWizard_Eng.lng" (Thanks ahmedaljaf for telling me this :good
13. follow the on screen instruction,
14. your phone should reboot and boot up with and old version of software.
15. restart the phone and go to fastboot mode.
16. extract the "recovery_signed.img" from your old "rom.zip" (not the rom.zip you create! ) and place it to some where.
17. flash the recovery by typing the following command "fastboot flash recovery recover_signed.img"
18. relock the phone
19. boot up the phone and try OTA
18. if the OTA download finish but fail to reboot to recovery update automatically, just manually boot to recovery and the update will be ok.
If you can return stock with this method, please reply and list the version here. And you can give me a "thanks" :good:

I wonder, if you put in the "rom.zip" the "hboot_0.95.0000.img" from an older RUU will you be able to downgrade the 1.28 hboot also?

There's NO way to downgrade hboot unless you have s-off.

They are somebody on chinese forum who use this method claimed he was able to do hboot downgrade through this method, but no one seem suceed so for.
Well, technically this method able to get you spoof ROM version because it check on your PC. While for hboot it validate the signature and version on the phone before upgrading itself. You can see the process if you push the firmware yourself via fastboot.

What if we hex edit the 0.95.0000 before we put it into the rom.zip to make it think that it's a newer version, will that brake the signature?
Sorry but I don't have the guts to try it myself

or you could just cook yourself a flashable zip from the rom.zip. Then fastboot flash rec and boot. Chances are ics wont boot on the newer hboots. Still the ota can be flashed as update.zip maybe.

usefull for some case

BRILLIANT! Absolutely brilliant! Thanks a million hokoonho. This method worked like a treat on my HK_621 HOX which was running ARHD 9.7.2

The method works well with ICS, even with other HTC model as well, but I am not sure if it still work will JB and latest hboot. But it won't kill your phone.

I have followed the instructions, and now I am at the point where I run "ARUWizard" and follow the onscreen instructions...
However, The test is not English, it is funny looking as if the language is corrupt/unrecognised.

Any advice?

It's OK, The RUU may not be able to select the right language to display, but It still works, since the RUU only use adb and fastboot to finish its process, and all these adb and fastboot are run in English...
A brief translation was made for those cannot Open the customRUU in correct language. go to OP for the pdf file

No problem, I have found an English version.
I am finding that I get a Error 170 USB error... I believe this is because I have an unlocked bootloader.
So I re-locked the bootloader... and found myself unable to get past the bootloader.
I managed to run the RUU whilst phone was at the bootloader screen,
Replaced the temp rom.img with the created rom.img in your guide,
But it ended up failing with a Error 132 signature check.
I am not sure how to proceed.

Don't relock at this moment, otherwise, you will not be able to flash the stock recovery. Unlock it first. Make sure USB debugging is on, then REBOOT to fastboot and start the RUU. Or...Try another USB cable, DON'T connect via a USB hub...

it depends on how much you have done to the phone while it's rooted
the system / and recovery must be completely stock for the OTA to work
if your s-off it's easy to flash an older RUU to restore your phone to stock
I have all the Developer Edition files needed here >> https://www.androidfilehost.com/?w=files&flid=21320
the steps if your s-on are
fastboot flash recovery recovery.img (use the one that matches your current firmware version)
then attempt to install the OTA
if the OTA fails just use the RUU for the latest version
for s-on you have to fastboot oem lock the bootloader to flash the RUU
fastboot oem rebootRUU
fastboot flash zip RUU.zip
fastboot flash zip RUU.zip
fastboot reboot

Hi
Thanks man, had some errors and mistakenly deleted the OS on TWRP...
now im stuck without a OS.
So just posted another thread...help me if you can

OK, for a start you do not have the Developer Edition. you first need to get back to stock which will more likely involve restoring this backup using TWRP 2.8.1.0 https://mega.co.nz/#!sYQFjSYK!Q6BZ4FxxQj7raBSxQFHBGRPYBFO69PwrjQxMo1bJaoA
You'll then need the stock recovery for 1.60.708.2 (that's the backup build) and then get the OTAs to get to Lollipop
@ckpv5 might be better to ask as he is the backup king but he is busy

Do this. Your firmware version is a few versions old and this will update it for you. You should probably learn how to return to stock (RUU) and use fastboot/adb if you are going to start flashing things, because things like this happen.

Let see how to help you .... how about give more details to get to know your device better
1. post result of command fastboot getvar all (delete the serial no. & imei no.)
2. What is written in Settings - About - Software information

Just to help you understand why it is showing what it is for TAMPERED, UNLOCKED means the BOOTLOADER has been unlocked to flash a CUSTOM SYSTEM, BOOT, RECOVERY, just read this one posting and post the details requested for your specific device by @ckpv5
Why it shows TAMPERED
http://forum.xda-developers.com/showthread.php?p=52331196
S-ON means the security for the CPU and NAND memory are protected from alteration, certain partitions on your handset you cannot alter without OFFICIAL SOFTWARE, so no need to panic that there is something wrong

hope that gives all the required info.

That suggests you have the variant from Hong Kong with the faster processor. It might be that a custom ROM has been installed.
I think I uploaded a stock ROM somewhere, so have a search of my posts. Also, check the returning to stock guides and the stock ROM backups. After restoring a stock backup, you should be able to upgrade to Lollipop.

These are my suggestions as there are no RUU available for this version
1. Install TWRP 2.8.1.0 (don't use 2.8.4.0 or higher as this is for higher hboot than 3.16.0000) - http://techerrata.com/browse/twrp2/m8
command fastboot flash recovery nameofrecovery.img then reboot
2. Download TWRP backup 1.60.708.2 (thanks to @BenPope) - https://mega.co.nz/#!e8AFCCQZ!2-2Lx1vxkg1xBq_Yhg_Sk9AOzdZsPrX2oOlxy-PLTF0
3. Download stock recovery - http://sourceforge.net/projects/htconem8/files/Recovery/1.60.708.2_recovery.img/download
4. Extract the downloaded 1.60.708.2 on PC
5. Boot to TWRP recovery and make a backup of boot only, this is to see where the backup goes on your device.
6. Transfer the extracted 1.60.708.2 folder and its content to the backup path on your device
TWRP/BACKUPS/SerialNo./BackupFolder
7. Wipe your device - in TWRP go to wipe - advance - select dalvik cache, cache, data, system (only these)
8. Restore the transferred backup
9. In reboot select bootloader

i did as you said. just came till step 1. dont i need supersu to root my device? are you asking me to flash the device with twrp and not root it using supersu?
how to do step 5 and 6 , can you explain please. thank you

To receive OTA updates you have to be STOCK device if I'm correct (it's all changed slightly since GUID partitioning), that means you have to install superuser after you update. The OTA will not be applied to an altered system.
Please correct if this is incorrect

From what I understand you can be rooted and so on, but you need to keep the stock recovery and software that comes with the phone. I know lots of people do that, switch back, update, then go to TWRP or so on.

Just follow the steps ... don't have to worry about root at this moment. That you can decide after step 14. The main point here is to update your device to the latest version.
Step 5 : boot into recovery, select backup - select boot only - swipe to backup - reboot
Step 6 : connect your device to PC, depends on where you select your backup to, (I believe it's in internal storage), open "internal Storage" with windows explorer (assuming you use Windows), Open TWRP/BACKUPS/SerialNo/here you see a folder with date on it, open this folder (here you see your earlier backup)
Transfer the extracted backup folder (step 4) to this folder
Step 7 : Put your device in recovery - go to wipe - advance - select dalvik cache, cache, data, system (only these)
Step 8 : In recovery select "restore" - select the nandroid folder - make sure all boot, data, system are ticked - if no data, leave it) - Swipe to restore
Then continue other steps

As expected... you have wrong ROM for your device. That's why no update.
Now you have a EU version 1.54.401.10
You should have HKG version 1.60.708.2
Check again the file that you supposed to download as in my earlier instruction.
You should have downloaded M8_1.60.708.2.7z from the link that I gave you

i have downloaded the same file. it is M8_1.60.708.2.7z
do you suggest me to try again?

I think you don't restore the correct file.
Check the steps again.
I suggest in TWRP/BACKUPS/serialno/backupfolder - the backupfolder that you have rename it 1.60.708.2 so when you select to restore, you will sure you select the correct folder. Don't forget to transfer the 1.60.708.2 contents that you extracted on PC to 1.60.708.2 folder on your device.

On post #7 I mentioned how to. Just don't download that backup and recovery, use the one that I gave earlier.
He started with 1.60.708.2 but yours is 3.32.771.10, so change those numbers 1.60.708.2 with yours 3.32.771.10 when you read it.

Thank you for all your help ckpv5. I followed all your instructions to the letter and i still have the same situation. When i start the device it goes to the HTC brand logo with "powered by android" at the bottom of the screen and just sits there.
I have posted pics of what i see during boot and the screen it hangs on any ideas?

Which nandroid backup that you try 3.32.771.10 ? It hangs maybe due to incomplete/wrong files restored.
Let's try again ..
1. Install TWRP 2.8.5.0 - http://techerrata.com/browse/twrp2/m8
command fastboot flash recovery openrecovery-twrp-2.8.5.0-m8.img
2. Download TWRP backup 3.32.771.10 - https://mega.co.nz/#!ZAZF0CqJ!_qmR7kgq5tTX1HrmwzMbS7jE94jp5AKobIF5NQJhmXg
3. Download stock recovery - http://sourceforge.net/projects/htconem8/files/Recovery/3.32.771.10_recovery.img/download
4. Extract the downloaded 3.32.771.10_ckpv5.zip on PC
5. Boot to TWRP recovery and make a backup of boot only, this is to see where the backup goes on your device.
6. Connect device to PC, select Mount, enable MTP then open Internal Storage, TWRP/BACKUPS/SerialNo./
6. Transfer the extracted 3.32.771.10 folder (not 3.32.771.10_ckpv5 folder) and its content to the backup path on your device
TWRP/BACKUPS/SerialNo./3.32.771.10
7. Wipe your device - in TWRP go to wipe - advance - select dalvik cache, cache, data, system (only these)
8. Restore the transferred backup - make sure all boot, data & system are ticked - swipe to restore
9. In reboot select bootloader
10. fastboot flash stock recovery that you downloaded - command fastboot flash recovery 3.32.771.10_recovery.img
11. reboot - check for OTA, download, install (you should have one OTA to 4.20.771.2)
13. done
When you do step 8 after swipe to restore, press power & power button together to make a screenshot of the progress and post here.
Need to see you have the correct files there.

Hello,
Please provide your phone's CID & MLDELID. To solve this problem, you need to either restore a stock firmware & stock twrp backup, or flash a stock RUU. Either way, the firmware & software must have matching cid & modelid.
As of right now, the data you posted indicate that your phone has mismatching firmware & software (x.xx.708 and x.xx.709).
Cheers

I'm really sorry i don't know how to get the information so, Could you please tell me how i can provide you phone's CID & MLDELID ? i mean the steps for it !

You can't just flash any file you please. RUU & firmware you want to flash MUST be specific for your device's region and variant model - in your case, you must flash ASIA-HK-CHT firmware & software. ATT & CINGULAR are US specific, and will not flash on your phone without modifications.
Instead, download the 1.60.x.x from the link provided by @Jerrel7, and the TWRP stock backup from 1.60.708.x provided below:
https://mega.co.nz/#!e8AFCCQZ!2-2Lx1vxkg1xBq_Yhg_Sk9AOzdZsPrX2oOlxy-PLTF0
Flashing the 1.60.x.x firmware and restoring the 1.60.x.x twrp backup will put your device in a stock condition that will allow you to receive official updates from HTC.
Cheers
P.S. let us know if you need help restoring the backup or flashing the firmware.

Hello. I had the same problem. Just solved it yesterday. The whole problem was in my MID. You have to change it for the RUU you want to install.
I was with MID for Singapore and i wanned to install European version. So i can't install the updates. After i changed the MID now i'm able to install every update.
Just follow this thread and you're done. Good luck, mate!

@Mike Smaan problem is a bit different from yours and he has a S-On device.
His problem is his device is running a Taiwan ROM on a Hong Kong variant device.
He needs to run a Hong Kong ROM to solve his problem and the right ROM version (4.18.708.12)
then he can OTA to the latest Marshmallow 6.16.708.1
Should he followed the link provided by @Jerrel7 on post #11, he should be able to fix his problem as simple as ABC.

Very well. Assuming you downloaded the twrp backup and stock firmware from my previous post, proceed as follows:
1. Download HTC Sync from the link below:
http://www.htc.com/uk/support/software/htc-sync-manager.aspx
If you already have HTC Sync installed, then upgrade it to the latest version. Otherwise, install the one from the link provided.
Reboot your PC.
2. Download the FASTBOOT PACKAGE from the link below:
https://drive.google.com/file/d/0B8L4pkbzdlR3eTlJSjdKVEdHX1U/view
Extract the file to "c:\fastboot" folder.
3. Download twrp 2.7.0.2 from:
https://dl.twrp.me/m8/
Extract the file to "c:\fastboot" folder.
4. Put the 1.60.708.x firmware zip you downloaded from my previous post into the "c:\fastboot" folder but don't extract it.
Summary:
You should now have:
A. the latest HTC SYNC installed.
B. A folder called fastboot in the root directory of your C:\ drive.
C. Your fastboot folder has the following files:
I. twrp 2.7.0.2.img
II. The zip file for 1.60.x.x firmware
III. htc _fastboot.exe
Let me know when you're done.

There are 4 easy steps to accomplish the task:
1. Flash twrp custom recovery. 2. Restore the twrp backup. 3. Flash the stock firmware. 4. Profit.
Let's get down to business:
1. Flash twrp custom recovery:
A. Boot your phone into fastboot. You do this by turning your phone off, then hold Vol- and power button. You're presented with a menu, choose fastboot (navigate the menu using vol+ and vol-) and press power to select.
B. connect your phone to your PC. Open a cmd window:
Type:
cd c:\fastboot
fastboot flash recovery twrp-2.7.0.2-m8.img
Flashing will take a few seconds, when its done, type:
fastboot erase cache
Now, on your phone, select "hboot", then "recovery", to boot into twrp.
2. Restore the twrp backup:
Unfortunately, twrp doesn't immediately create the directory structure for where you'll put the backup file you downloaded. So, we're going to start by creating a backup of your current ROM:
A. Select Backup button in twrp. Select "external sdcard" from the menu at the top, and proceed to create the backup.
B. On your computer, extract the twrp backup file you downloaded, and copy the extracted directory to your phone's sd card. Put it in:
/sdcard/twrp/backups/"serial number"/
C. On your phone, tap restore, and choose the backup directory you just copied to your sdcard. Proceed to restore.
D. Choose to restart your phone and select Bootloader.
E. Select fastboot.
3. Flash the stock firmware:
A. On your PC's cmd window, type:
fastboot oem rebootRUU
B. WAIT UNTIL your phone displays black screen with HTC in white, then type:
fastboot flash firmware M8_1.60.708.2.zip
C. Once more, type:
fastboot flash firmware M8_1.60.708.2.zip
D. Reboot by Typing:
fastboot reboot
4Profit.

I know that you ignored my previous posts and other people post who tried to help you with proper method .. but I still pity you and I don't want to see you'll end up in a brick or soft brick due to wrong commands/instructions.
You get error when flashing firmware - reasons :
1. That command given to you to flash firmware - fastboot flash firmware M8_1.60.708.2.zip - is wrong.
The right command is fastboot flash zip M8_1.60.708.2.zip
Running a wrong command may brick your device but you are lucky because your device is S-On, so no harm just error.
2. Being a S-On device, you won't be able to install a very low version firmware 1.60.708.2 when your current one is 4.18.708.12
Only S-Off device can do that. To have S-Off you need to spend USD25 for the app .. and are you willing to spend USD25 to S-Off when you can fix your problem with proper method free of charge and needs only 2 main steps : ?
1. Restore 4.18.708.12 TWRP backup
2. Install 4.18.708.12 stock recovery.img
then you can update to the latest - 6.16.708.1

You can try these B., C., and D.
But, again using a very low version 1.60.708.2 backup on a Lollipop firmware 4.18.708.12, you may have one of these :
1. It will be successful updates but you need to do many OTAs
1.60.708.2 --> 2.11.708.2 --> 3.32.708.4 --> 4.18.708.12 --> 6.16.708.1
If it is successful then it's good but if it is not, you'll get below.
2. You may have a blank screen either between OTA 1.60.708.2 --> 2.11.708.2 or OTA 2.11.708.2 --> 3.32.708.4
3. You may lost your wifi connectivity either between OTA 1.60.708.2 --> 2.11.708.2 or OTA 2.11.708.2 --> 3.32.708.4 but you can proceed further with your mobile data or use a Internet Pass through on your PC
One last note ... never use a 2.7.0.2 TWRP recovery as that is the most buggiest TWRP which will remove your OS version on your bootloader.
Good luck.
