[TUT] Re-flash stock ROM (RUU) after bricking a rooted device (for noobs)

Before you start, you will need to set up your computer to properly recognize the phone. You probably did this when rooting originally, but just in case... Install SDK tools for Android, Java runtime, and HTC Sync.
About HTC Sync: The only reason you need HTC Sync installed is for the USB drivers that come with it. But the program itself has been known to cause conflicts. Make sure that HTC Sync is not running in the background by opening Task Manager in Windows and killing it if you find it lurking in there.
Here we go:
1. Download the correct RUU (ROM Update Utility) for your device from androidfiles.org. Make sure you download a Primo_C RUU for a CDMA device (no sim card) or a Primo_U RUU for a GSM device (uses a sim card)!! Also make sure you get the correct RUU for your carrier.
2. Charge the battery above 50% or for at least one hour. If the battery dies during the flashing process, you could hard brick the phone!
3. Run the RUU until the wizard comes up. While the RUU wizard is open, find the temporary folder it created. (Open Explorer in Windows and type %temp% in the navigation bar.) There will be two folders with long encrypted names. In one of them you will find ROM.zip. Open it with 7zip and extract recovery.img or recovery_signed.img. Put it in the location were you've installed Android SDK tools. This is the stock HTC Recovery and it is needed to run the RUU.
4. Boot the phone into bootloader (power off, hold down volume and press power) and highlight FASTBOOT using the volume rocker and pressing power. Then connect the USB cable. You should see FASTBOOT USB.
5. Open a command prompt in Windows and navigate to the folder where you installed Android SDK tools. Flash the stock recovery extracted in step 3 above using the following command:
Code:
fastboot flash recovery recovery.img
or
Code:
fastboot flash recovery recovery_signed.img
6. Relock the bootloader using the following command:
Code:
fastboot oem lock
7. Re-run the RUU. It will restore the device to it's original condition, locked (though *** RELOCKED ***) and unrooted.
Once the install is done you'll have unlock the bootloader again using the token you already have from the first time, reflash CWM Recovery and re-root. All this will be 10x easier than the first time.
If you do re-root your phone, be 100% you backup the stock ROM in ClockworkMod Recovery before making changes!

Hi
Thanks for that perfect decsription exactly when I needed it
I just had a weired effect with my new windows 7 laptop that I want to share.
I installed the USB drivers and "fastboot devices" showed my HTC fine
but even flashing the stock recovery image was not working.
So it was stucking in the "Sending" part and never continued.
I then moved to my old laptop with Vista did exactly the same things
and there it worked without problems.
I disabled virus scanner, checked for htsync and used the original USB cable
without success.
But now I know why I normally never touch Windows and only
work on linux

Use the correct RUU package for your device

Another way of saying it is that you downloaded the wrong RUU for your device.

not working
it keeps on saying waiting for device n does not proceed further
i tried installing the drivers again but that doesnt help either

"Waiting for Device" at fastboot usually related to bootloader driver. You need Android USB Driver

Hi folks,
I've bought my One V in late may and I had 2.08 ROM.
Now I've tested some roms and I wanted to revert back to stock rom.
I've downloaded RUU_PRIMO_U_ICS_40A_HTC_Europe_2.08.401.2_Radio_20.72.30.0833U_3831.17.00.18_M_release_263376_signed, and got recovery_signed and boot_signed images. Then I've went to fastboot, did flash recovery and boot partitions, and oem locked bootloader. Afterwards I booted my phone and entered PIN. Then I fired up RUU*.exe file, and I have 155 error. What the heck? Something I missed?
greetings!

Flashing RUU to revert to stock
- you must have the correct RUU for your device.
- if you are not sure, download CID Getter from Play Store and run it, it will show your CID.
- with your CID, you may be able to find a correct RUU for your device
then (even though some people may not agree with this, but this will bring no harm and it is noob-proof) do this:
1- flash a stock recovery.img
fastboot flash recovery recovery_signed.img
fastboot reboot-bootloader
fastboot erase cache
2- flash a stock boot.img
fastboot flash boot boot_signed.img
fastboot reboot-bootloader
fastboot erase cache
3- re-lock bootloader
fastboot oem lock
fastboot reboot-bootloader
fastboot erase cache
4- flash RUU
NOTE: There is no boot/reboot and enter pin in between.

[Q] Can't access recovery or start the 'normal'phone

Hello,
First of all, it has been a while since i've done tweaking my old one X, but my dad uses the phone now, and he asked me to update it, since the old rom crashed sometimes.
now i found out the was android 4.2 roms available for the one x, and wanted to flash them.
although, i figured out, i needed a higher Hboot, since mine was at 0.95, i needed 1.29+.
tried to figure out how this worked, and i thought i finally knew it, but than the last step wouldn't want to complete, while in RUU, it didn't want to do what it had to do..
so after some hours shouting at my pc and phone, i decided it had enough of it, and would just flash another rom, which didnt need the higher Hboot.
but now comes the crap...
i downloaded one_X_sfied rom, and i though hey its finally working, i saw the bars going green, and all the stuff..
but while rebooting the phone, it wouldnt go past HTC - quietly briliant - logo. so i decided to install it once more via recovery.
again all bars go green.. but this time it wouldnt start the phone either..
so i wanted to go back to recovery, but now it wont load recovery either! when i click on my recovery, it boots the phone again, and keeps rebooting at HTC logo..
i found out i made a mistake, and didnt flash the new kernel for this rom, i was little bit hurried.. so i guess overlooked it... stupid me, i know....
anyway, only thing i can access now is the fastboot and hboot, my bootloader is unlocked, and hboot is 0.95.
my cidnumber is: HTC E___11
there was another number, i thought RUU number, but i don't know the command to get it anymore, don't know if i need it..
anyway, now my question..
how do i ever get this phone working again, if it's even possible...?
any ideas?
thanks alot for reading and applying.
(sorry for grammar mistakes )
- edit -
now it somehow restarted the bootloader, and stops at ''checking sd card update...''
which means. i cant even get into fastboot either.. guess im screwed up now ... ----------lucky me, it shows the fastboot again.. sweat for nothing

what is your version?

what version do you mean?
RUU?

Have you flashed the right RUU for sure ? Try flashing again and remember that you have to relock the bootloader before !

i did not flash any RUU.
i don't know how to get that code, not the E11 thing, but those numbers.
if i am right i have to:
get the original RUU software.
flash this through fastboot using my CMD on PC
relock bootloader first.
but i need the correct RUU file first, and i don't know where to find, because i need that numers, i forgot the command to get it, and cant find it on internet now :\

anyway, is this correct? what i say above. -> download correct RUU file -> lock bootloader -> flash via PC -> than something else?
if im correct, i will have a original, non-rooted HOX. correct?

4. cammand: to ruu mode? - forgot this one, but i can find if i need it
5. run the downloaded RUU, - i have to run as admin on my PC?
thats it right?

No....
Boot to bootloader and relock it
Fastboot oem lock
Then put the phone in the locked bootloader and run the ruu with administrator rights.
You can use this one

1. Boot your phone to fastboot mode by holding power+vol down button for 10 secs..(if your phone keeps restarting in normal phone mode, go to Setting>Power and untick Fast boot)
2. Plug your phone into your PC and open a Command Prompt.
(windows XP - Click Start > Run > type CMD in box then press OK
(Windows 7 - Click Start > type CMD in search box then press Enter)
3. cd to the location of your fastboot files folder
4. Relock bootloader - type command:
Code:
fastboot oem lock
The phone will then restart into fastboot again showing "RELOCKED"
6. On your pc run the RUU that you downloaded earlier, follow the steps as prompted and patiently wait for it to finish.
REMEMBER your phone should be charged ABOVE 50% AND if the ruu or restore is INTERRUPTED 4 any reason during restore your
phone MAY be PERMANENTLY BRICKED..

Trouble installing RUU?

I'm trying to install the latest RUU for my developer edition. The RUU loads till the point where I accept the agreement and then nothing. I'm on Windows 8.1. Here is where I got the RUU from http://www.htc.com/us/support/htc-one-m8/news/
Any idea why is this happening or how to fix it? I'm having all sort of problems with the phone at the moment. I'm giving a RUU a try to see if it fixes it.
Thanks in advance!

Same thing happens to me, no idea why. Works fine in Windows 7. some people say it's to do with needing a C++ Update but that didn't work for me either
What you can do, though, is once at the T&Cs screen, open a run box and type in %temp% and it'll take you to the Temporary Files folder on your PC and if you look at the newest folders there should be 2. One will contain a compressed file called 'rom'. Copy this to your Desktop, then to a microSD card and flash that via HBOOT or flash it via RUU mode using htc_fastboot.exe (which you can find here)

Could you refer to this C++ update if you happen to remember which one?
How do I flash the rom file through HBOOT or the RUU mode using htc_fastboot.exe (87.7 KB)?

To flash the ZIP in RUU mode
fastboot oem rebootRUU
htc_fastboot flash zip rom.zip
And unfortunately no, I don't know which update it was as didn't work

I've never done this through RUU mode before, so I'll double check with you.
I'll open normal fastboot. Copy the rom.zip to the root of theSD Card or to the same folder where fastboot is? Also where to place HTC_fastboot.exe, same as fastboot or in the root of SD Card? Then I'll enter the command fastboot oem rebootRUU then htc_fastboot flash zip rom.zip? I'm sorry for the basic questions, thanks a lot!

If you're flashing it manually you don't copy it to your phone, just put it in your fastboot folder along with the htc_fastboot file and then do it all with the phone in fastboot mode

This is the same like applying the RUU exe? This will wipe everything and install everything from zero, right? On HBOOT I have a modified software status , is this going to be fixed as well?

Yep, completely resets the phone to factory defaults

@EddyOS
Sorry for asking more questions, but last time I applied a RUU was with my M7 when I first bought it. If I'm going to apply the RUU exe, does i have to be on fastboot or while the phone is on? Flashing the rom.zip, do I have to flash or format anything through fastboot or should reboot fastboot or simply reboot the phone? Applying RUU, does it reinstall HBOOT? Sorry and thanks again!

My previous post answers your last bit - it puts EVERYTHING back to factory and the latest versions
RUU.exe you can run when in Android or in fastboot mode, RUU.zip HAS to be flashed in RUU mode.
I've said everything you need to know so if you still don't get it, don't bother trying it

I'm just making sure. I don't have another phone at the moment and limited 3G internet connection, so I don't want to get stuck with the phone not working or downloading things twice. Sorry for repeating the same questions though

hello...sorry for the noob question....is there a way for me to install the RUU in linux....in window 7....it is always askin for me to install drivers...etc...n error msg...device not found...etc....i dont have those errors in linux....

never mind...I found it...

A5_CHL Virgin Mobile Fastboot and ADB won't work

I'm trying to reset this phone to stock and it just isn't cooperating. I had fastboot working enough to load the stock recovery on there but than I went to try to use the RUU it would just crash after the Terms and Conditions. So I looked up the solution and it was downloading a bunch of C++ Redistributables. It still didn't work and than I noticed it also wanted me to have the HTC Sync Manager installed so I did that. When that didn't help I uninstalled it. Now when I go into fastboot it just says "waiting on any device". It says Fastboot USB on the phone. The Device Manager reads it as "My HTC". I've been at this for hours and any help at this point would be a blessing.

Try to just extract the rom.zip file from the exe and flash that. You run the RUU and while it's running you click search and %temp% to find the files running. It's in one of the long numbered and lettered files. You can copy that and run using fastboot or rename it to OP9CIMG.zip I believe and put it in the root of your ext SD card and it should run automatically when you enter the bootloader.

Oh, ok. You didn't mention that part so I didn't know. You say you had fastboot running initially enough to flash the stock recovery. Does that mean you've had issues with it from the beginning? I'd try to download the slimmer version found here on XDA and see if that's the issue. Other than that and the first suggestions I gave you I don't have much else. I have this same device a5_chl and haven't encountered this issue with mine. Sorry your having to deal with this. It's not fun.

Is your bootloader still unlocked?
I had to flash the recovery, then run 'fastboot oem lock' before I could run the ruu without errors.
