Hi,
me too i want to back to stock but i think it's to complicated, so what i know : 1st backup ur current custom rom (for safe ^^);
2nd restore stock recovery; 3th restore RUU for your A9 (hiaeuhl or hiaeul etc ... ) that all i know but i heard that we need to restore the /system partition (i dont backup this before install cm13 :/ ) if anybody know what to do exactly :fingers-crossed: :silly:
the s-on/s-off scare me too xD i dont know what to do to restore stock properly ^^' maybe we have another thread for that i look later

S-on/off has nothing to do with going back to stock (unless you want to change version).
if you flash RUU you'll be 100% stock but you'll lose everything including root
bootloader is fine i guess.

Verify that you have the correct RUU for your phone. If you do, and it still isn't working, try the RUU .exe while your phone is in download mode. Also, make sure you're not using a USB 3.0 port. Sometimes that can cause problems.

Download 1.27.161.6 from post #1, then follow the steps from post #2. I'd try the first method, first.
This should work unless your firmware was updated to a later version than 1.27.161.6.

Gotcha, I'd recommend that you use the external sd/stock recovery method to return to stock. That's probably the most bulletproof way to return to stock. If you no longer have the stock recovery, no problem. It's pretty simple to extract the recovery from the RUU and flash it first.
Also, did you download the RUU again? It is possible that you may have a corrupted RUU.zip if it is crashing your fastboot.

So me i'm on CM13 nightlies with twrp and boot.img modified, to back to stock i had to flash stock recovery( * ) than flash the RUU( ** ) ? that all ?
*: i had to extract it from the RUU coresponding i'm good ? ^^"
**: my cid is HTC_034; my mid is 2PQ910000 so i had to take the 1.10.401.7 RUU i'm good ? ^^' or the 1.56.401.70 or 1.27.401.5 ? i'm lost, on my dowload mode it's say i'm on 1.10.401.7 (but i'm on cm13 latest nightlies ... >< )
Than, when i'm succefully back to stock if i choose to return to cm13 i can flash my backup(recovery+boot+/system+rom) of cm13 with twrp if firmware doesn't upgrade with OTA on stock i'm good ?
Lots of question i know ^^' thx for help.

If you use the sd card method (copy the RUU.zip to external sd) fastboot is no longer necessary. The RUU is flashed using the stock recovery. There's no fastboot to crash at that point.

You shouldn't have any trouble returning to stock at all. I've had quite a few Heineken at this point, but flashing boot, recovery, and system of your stock rom is no problem at all if you have backups.

Could you state how this is done? I recently moved to the A9 from having the M7 since it came out, (which had NO external SD card support) , so this is the 1st I'm hearing of being able to apply an RUU Without fastboot... Does the RUU have to be in any specific folder, or the root of the external SD card?
Any details would be GREATLY appreciated.

This http://forum.xda-developers.com/showpost.php?p=63640734&postcount=2 explains in detail. I THINK this utilizes the stock recovery in the process. In any case, it allows flashing an RUU.zip without any fastboot involvement.

It's possible to return s-on and bootloader locked (not relocked)? Thank's.

Yes i know but u dont understand me i think, for the RUU there 3 version for my phone 1.10 -> 1.27 -> 1.56 so witch one i had to take ? CM13 run with 1.27 ? 1.10 with cm13 isn't possible no ? because on my download mode(bootloader) it's say : OS-1.10.401.7 in theory i would take the 1.10.401.7 RUU but a man (on this forum) tell me this was a bug of cm13 and its run with 1.27 it's wrong ??

Any one of the three would return you to stock, as long as the version number is greater than or equal to the firmware that you have installed. (Which is the topic of this tread...)
As far as compatibility with CM, you should check that thread...but I think CM is compatible with the 1.27 firmware. If you're still s-on, you DO NOT want to upgrade the firmware to a newer version than CM supports, if you intend to use CM.

I'm sure it's possible...just a matter of finding exactly what you need to hex edit and where it is. Experimenting with this likely carries a chance of bricking your device, since the variables would have to be used by HBOOT and/or download mode. Maybe someone else has already accomplished this?

You must use htc_fastboot.exe to flash a RUU, not the regular fastboot.exe from the android sdk.

The stock recovery is not used when flashing a RUU from the sdcard. The bootloader handles the process, not the recovery. Stock recovery isn't needed at all, using fastboot or the sdcard methods.

Urgent firmware flash help.

Hello,
I neef urgent help, one day i was trying to flash custom recovery to my razr hd, it is i dont know 925 or 926. It is 16gb.
I was unsuccess to flash recovery then i was everytime getting fastboot msg and i had to press normal recovery everytime. Now i tried to factory data reset my mob and it is stuck on logo and time black screen with dots..
I have rsd lite but i think firmware i am not getting exact one thats why it is nog flashing... Please help me what to do. I have attached pics of recovery and fastboot.

I can help you but I need to know if you have correct drivers installed unless your using linux otherwise you need to install the correct drivers for the device. xt925 i think is gsm not sure and the xt926 is cdma 4g. I also need to know what version of android you were using so we flash the correct firmware(e.g, jelly bean, kit kat and so on). I also need to know what version of rsd you have because you might need to use a newer version. After we get your device back to life. I will give you the link to the correct recovery for the device. footnote: you will need to re-root device after it is flashed back to life, then flash correct recovery. You can only flash recovery if you unlocked the bootloader witch you do after device is rooted. 0 means bootloader is locked and 3 means it is unlocked. If you flash any recovery with a locked bootloader than you can soft brick or hard brick the device. If this is what you did and your just stuck at the Moto M than it just needs the correct stock firmware flashed so it can come back to life.

Please help: How to return htc u11 to stock

Hi guys,
My phone now is on LeeDroid custom ROM (Build 1.03.401.6.9_g CL923215)
What are the steps to return the htc u11 to stock please?
The original software number of my phone is: 1.11.400.4
EDIT: I went to: https://forum.xda-developers.com/showpost.php?p=72425224&postcount=5
& downloaded stock recovery & nandroid TWRP backup (for 1.11.400.4).
However, I couldnt flash that nandroid TWRP from TWRP recovery.
Long story short, I just got the phone today, I made a big mistake by not inserting the simcard in & testing to see if the phone working or not.
So, I went straight through the process of unlocking bootloader, installing TWRP, Rooting, Installing custom ROM without making a nandroid backup.
For all that, the phone did not recognize the sim cards (tried both my sim & my gf's sim. not working)
The store will take back the phone as long as I return it to stock.
Thanks for your help!!!

You'll need to download the stock rom for your verison (ruu). Hopefully one is available. Check the guide section here.

Restore the TWRP backup, check everything is working, then flash stock recovery if you need to. The stock Nandroid should include recovery asfaik. I'm more of a trial and error guy lol. Read guide pages to know for certain, check HTC 10 guides, same steps.

Get the one from here and follow instructions. That's what the thread is for. https://forum.xda-developers.com/u11/how-to/collection-htcu-u11-ruu-firmware-t3612048. Sorry i don't have time to do the leg work for you (i'm out atm), but it's all there.

download this Official RRU firmware and install it https://forum.xda-developers.com/u11/how-to/unlocked-htc-u11-software-update-6-19-t3624814

Use the ruu, you might need the HTC drivers but in the future never not make a backup, 15 mins could save u a major headache

Finished downloading & now I got an ERROR installation, something like a wrong ROM, probably because I'm currently on LeeDroid custom ROM (Build 1.03.401.6.9_g CL923215)
Please advice
Thank you

Your going to need a full signed RUU zip matching your original firmware and CID buddy.
Based on your original build number its an Indian dual SIM device so here is the ruu:
https://www.androidfilehost.com/?fid=817550096634780026
1. Rename it to 2PZCIMG.zip
2. Lock your bootloader
3. Drop the zip on your external SD card.
3. Boot to download mode, at that point you will be prompted to flash... Accept... Profit.
If you don't have an external SD.
1. Lock your bootloader.
2. Boot to download mode.
3. Open a cmd window and run the below commands.
fastboot orm rebootRUU (hit enter)
fastboot flash zip (drag the zip into the cmd window then hit enter)

On the PC side, what was the exact error message?
you can ignore the warning from the phone side.
I had a similar issue the other day, but then I was able to run the RUU upgrade to rest my phone back to stock as I had to ship it back for a refund, to get the new Red ones
When I ran the RUU thing it wouldn't detect the phone, did a few things, and then it was finally able to detect the phone.
and when it started updating the Boot image it hung for a long while, I had to restart the phone back into download mode, then run the RUU again, and it was able to continue from there.

If you flashed a full Oreo firmware instead of just the dsp, radio and bluetooth images you won't be able to downgrade. Firmware can only be downgraded if S-OFF, and that's not yet available on Oreo. If that's the case you are very well stranded on Oreo for the time being.
To be honest those things are quite basic knowledge you should have learned before you started tinkering with your device. Today most people just start flashing away, while I - when I started it myself back on the Desire days - read up on XDA and other forums for about three weeks to know what is to know. Still reading and learning new ways to accomplish what I want from instructions by developers, themer and many other users. Might never stop doing so until I'll stop tinkering.

If he has the wrong or to old fastboot on his PC, he won't be able to flash the RUU, due to file size restrictions in older fastboot versions. On the other hand, I'd personally prefer the SD card method instead of fastboot RUUing, as that always avoids such problems.

I download ruu firmware, put it on root of ext. Sdcard.
Reboot the phone to download mode. In the starting of download mode, it give you to choose, vol + to flash, vol - to cancel.
The ruu firmware must rename to "2PZCIMG. Zip",
If you have twrp, you must wipe data.

May I ask why you decide to switch back?

[How-to][ruu] Flash ruu.zip to factory

If you have some problem with your phone like me (Settings app fc always) you can download your RUU.zip and flash it.
If your bootloader unloced no problem no need to relock.
Go to download mode and type:
Code:
fastboot oem rebootRUU
Now your booted to the black HTC screen. Make sure your Rom.zip file is in your adb/fastboot folder
Code:
htc_fastboot flash zip Rom.zip
This takes a couple minutes and you will most likely get a error (pre-hboot update: please flush immediately) and maybe your phone reboot sometimes.
Make sure device is still in ruu mode(black HTC screen).
Let it run and it should finish this time
After completed :
Code:
fastboot reboot
It will reboot to a fully stock build.
Just remember, anytime you get a "flush immediately" error, just make sure your still in ruu mode and reflash the zip.
The most common error is typically :
FAILED (remote: 90 hboot pre-update! please flush image again immediately )
Enjoy your stock phone again.

You can't make a downgrade with out S-OFF!!!

HTC Fastboot in 2nd post. You only need paste to fastboot and adb folder.

If you want to decrypt RUU you can use : HTC RUU Decrypt tool . You will got a system.img, boot.img, recovery.img etc...
HTC Fastboot exe : https://androidfilehost.com/?fid=95916177934550031

Thank you. I was wondering how to flashing the zips.

Thanks OP.
I want to extract the stock boot and recovery from RUU but it appears the format of RUU provided here is different from the others.
Is it still possible to extract them?
And could this RUU rename to 2Q4DIMG.zip and place to sdcard and flash from device with download mode?

If y want to decrypt the RUU y need this : HTC RUU Decrypt tool
You can decrypt the ruu file and y can find the system.img, boot.img, recovery.img.
I think you can place to sdcard but i didn't try this.

Hi, I flashed the firmware from the microsd (fimware 1.10.400.23). As with htc 11 normal model, just rename the firmware file corresponding to the phone model in 2Q4DIMG.zip, put it in the sd card, start htc u11 plus in download mode and it's done. There is no need to have unlocked bootloader.

I tried to downgrade from 1.24.401.2 to 1.10.401.23 with the SD-card method (non root) because of wakelocks and the low percentage of Deep Sleep of screen time off (confirmed today by HTC Nordic today and that HTC are working on a new update. The support person didn't know any ETA).
Everything seems okay underway when flashing but after boot and finishing the setup procedure, Wifi, Google account etc. I'm still on 1.24.401.2. I used the 1.10.401.23 in the first post.
Have anyone else tried to downgrade with non root?

My HK model got an update today to 1.24.400.03 and devcheck is reporting 61% deep sleep.
I have had almost none since the update from 1.10 to 1.24.400.01. the .03 update seems to have solved this.
