HTC One M8 Canadian RUU

[marawan31]

I need an HTC One M8 Telus/Koodo RUU for my phone. I flashed GPE Rom and it works great but i want the 5.0 update of my carrier but i can't flash it because i am on a custom rom so i would like to revert back to stock in order to flash the 5.0 update.

Any help or suggestion would be appreciated

Go back to stock, and take the OTAs. Then re-root and enjoy your new firmware.

I cant do that because i am not s-off

Incorrect. This is the method that you use if you are not S-Off.
If you were S-Off, you would just update firmware manually, with no need to go back to stock.

I would suggest asking if anyone has a link to one in that thread.
I'm on Telus too, but I am running WWE firmware. I ALWAYS have the new firmware before Telus. Just sayin.
S-Off is a good thing to have. I know it seems like $25 is a lot to pay to get it, but if you think of all the hassle it saves trying to update firmware, and the other freedom it gives you (I'm using the Sprint Harman/Kardon version's audio files and ADSP) it is very reasonably priced.

i just flashed the one saying 3.x. its a 5.0 nandroid backup and all is working except wifi for some weird reason. looks like the firmware wasnt updated.
i have nothing against paying 25$ its just that sunshine never worked for me. It always said it didnt like my kernel and that i should try with a stock and i was too lazy tbh

Use 3.34.661.4 backup for 4.4.4 but wifi will not work on your device yet because you have hboot 3.18.0000

Find the 2.23.661.2 -> 3.34.661.4 - thanks @shaboobla on this thread : http://forum.xda-developers.com/showthread.php?t=2701376

Extract out firmware.zip from that OTA zip (with 7-zip)

then you can flash this firmware in RUU mode (but you need to relock bootloader because your device is S-On)

Later .. you can check software update and accept OTA to 4.20.661.2

how would i flash a firmware in RUU mode? you mean like renaming it to some weird name like PG.... and placing it in root of sdcard and going in fasboot? or is it something else because tbh i have never heard of flashing something in RUU mode

thanks for your help, really appreciate it.

EDIT: I just found out i can go to RUU mode with "fastboot oem rebootRUU".
so i can flash the firmware with "fastboot flash zip firmware.zip"
thanks again for all your help guys

2. Boot to bootloader
3. relock bootloader - fastboot oem lock
4. flash the firmware in RUU mode
fastboot oem rebootRUU
fastboot flash zip firmware.zip
fastboot flash zip firmware.zip <---- again for the 2nd time
fastboot reboot
5. check software update
6. accept, download, install
7. done

Just don't forget to relock bootloader before flashing firmware.zip
fastboot oem lock

fastboot oem lock

yea i was going to do it and also for the sake of completeness flashing the stock recovery(3.34.661.4) after the restore, just in case someone else has the same problem

 

[ckpv5]

You can do that but not really needed because the signed firmware.zip will restore stock recovery.

oh didnt know that, i guess i wont then

 

[marawan31]

I just wanted to thank you guys for helping me out!
I did everything and now i am on android 5.0.1 (although i ran into a small problem: process com.android.phone is not responding, factory reset from recovery fixed it)
Hope this thread helps someone else with similar problems

Sorry for reviving such an old thread, but I'm trying to get my htc one m8 up and running again. It was functioning on lineage os but wasn't very stable, couldn't find any other roms that would successfully flash on it, I decided to try and go back to stock after a few beers one night night, now the phone has been sitting in a drawer with no os or recovery on it. There doesn't seem to be any still functioning links to any Canadian RUU's that I can use. I'm not s-off, bootloader is "relocked". I'd like to go back to stock marshmallow because I only use this thing to play music and as a tv remote. I'm hoping someone might have an old RUU lying around.

I guess if not my best option is just to unlock the bootloader again and try flashing the same lineage os again. Since I relocked does that mean I have to go through the htc website to get the unlock token again like I did ages ago? They probably don't even have this phone on there anymore. Hopefully I didn't actually turn this thing into a brick.

Photo link is coming up with 404 error for me. Better to do fastboot getvar all, then post the results (cut and paste from command prompt), so we can see all the info on the phone (delete IMEI and serial number before posting).

If you can be more specific about which ROMs you tried (plus info about your device from getvar as noted above), then we might be able to advise why they did not flash. Did you get error messages, and if so, what exactly were they?
I decided to try and go back to stock after a few beers one night night, now the phone has been sitting in a drawer with no os or recovery on it.
What exactly did you do (step by step, with any relevant file names, etc. - more detail is better).
I presume you intentionally relocked the bootloader in attempt to run some RUU. But would like clarification on this (and where that happened in the sequence of events)

Far as I know, Canadian versions don't have RUU.

One option (maybe the best one) is to restore a stock TWRP back from the collection: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
You will need to unlock the bootloader to do this. You can either reuse the unlock bin code you used originally (if you still have it). Otherwise, you should be able to request a new bin code from HTCDev.com. Far as I know, that still works for this phone.
