[Q] Troubles at UnRooting M8

Hello there!
I know there are many threads and questions about unrooting, but I haven't found anything useful to me (or I just don't understand them) and also I'm new to the whole root/unroot thing.
Here is the story. I rooted my device via TWRP Recovery. Then I tried to get S-OFF using Firewater. When I wasted like a few days trying to get this done I discovered that my device is "Patched by HTC" so I cannot use Firewater anymore to get this S-OFF.
The whole thing was to convert my M8 into a GPE version. Now I'm trying to revert my phone back to stock ver. because I have no need in root.
So is it possible to unroot my phone?
My CID is HTC_622
Software number is 1.60.708.2
Thanks in advance!

Thanks for the reply.
I wish there was more detail in your post: like what software should I use to flash stock?
Should I download some rom for that?
As I said, I'm really new to the whole thing.

1. Flash your backup in TWRP
2. Once restored and confirmed working, flash the stock recovery image for your software version in fastboot the same way you flashed TWRP (fastboot flash recovery <nameofrecovery>.img

Hey I've been googling for hours for this too.I know this is an old post.
I am one of the unfortunate people do get a 1.60 up
Update on CID HTC__622
I have surfed the page with the list of nandroids, however there is no stock recovery that begins with 1.60. From other research it states that the first two numbers are the most important whilst flashing recoveries.
Any information would be really helpful
Thanks

Help with s-off and ota

Hi I have tried to go back to stock to do ota, and now I'm s-on can't get s-off again or get the ota to install or flash, I'm stuck and in need of some.Help please

Not enough info. Did you restore stock recovery? Why can't you install OTA (what error messages, etc.)?
Did you turn it back to S-on after doing S-off? If so, you didn't need to, as s-on is not required for OTA.
What is the current state of the phone, is it bootlooping, etc.?

The error.message from htc says the phone is rooted or tampered with and.cannot perform.update, I tried recovery and.relocking, to see if i can do the ota, same.error, I tried to flash the ota by going into the recovery screen after recovery to stock, where hold volume up and.press power brings up a menu to install from device or sd card, no luck there, says invalid cid

Current state of.the phone is rooted twrp, unlocked, s-on (firewater doesn't.work anymore), Harman karman installed, supercid, phone has boot looped but supersu did a update, so far no more boot loop, kit Kat 4.4.2, software #1.55.6664

It's a guess but H/K is a mod changing Kernel and will thus prevent OTA from succeeding as far as I know.

Perform a clean install of a TWRP Backup (of course one that fits your CID/MID, which is why @zhiarw asked for it I think) without this mod. After this reinstall stock recovery and try OTA again.
This should do the job.

As stated, supercid at the moment, original cid is saskt001

Go back to clean but older ROM and try Firewater again.

Ok, then find backup corresponding to your FW for this CID without H/K Mod, install using recovery (e.g. TWRP), go back to stock revocery.
After this you should be abled to perform the OTA.

Thanks, I'll try to find one

CID SASKT001 and BM___001 share the same software no.
So you can use 1.55.666.4 under CID BM___001 backup and recovery.
Download from : http://forum.xda-developers.com/showthread.php?t=2 701376

So is there a step by step for a clean twrp install ? Guess I didn't do that since I'm having issues

It's quite strait forward:
1) flash stock backup using TWRP
2) flash stock firmware using fastboot commands in bootloader
--> reverted to stock
3) check for OTA in settings menu

Congrats, the One is a good choice.

Ya I'll have to try when I get home, I'm hoping it works, and then I'll have to see what benefit there is to rooting since I haven't really done anything since.doing.the Harman kardon

if you install a room on your phone or use xposed tools there are lots of benefits of rooting

tried this, in twrp tried installing the backup, it failed, so no luck so far

[Q] Deleted os please help.

Hi Guys,
I tried to get s off on my phone but instead I seem to have deleted the os with TWRP.
I have an international or chinese model (HTC_621) and tried to install a firmware using Vomers guide but when I type adb wait-for-device push firewater /data/local/tmp it just hangs so I cant install a firmware as Im not S off.
Unfortunately I didn't do any back up
Am I going about this the right way? I just want to get my phone back to stock.
I will appreciate any help, thanks

COLLECTION of Stock backup's
There's a nandroid backup for your CID in that thread.
Your post though... what the heck does TWRP have to do with getting S-OFF? So you pushed a command it hung for a bit and you decided to do a full wipe instead to cut down the hanging time? What does A have to do with B

You don't need S-OFF to flash a ROM.
You also don't need S-OFF to restore a nandroid backup.
The only thing you need to flash a custom ROM is an unlocked bootloader and a custom recovery, that's it.
You'll need S-OFF for other things like making changes to the HBOOT(Fixing tampered flag) downgrading firmware, converting to other devices(Changing of MIDs and for GPE changing of partition sizes) etc. For normal custom ROMS(Viper, ARHD etc) just flash it through custom recovery.

Firewater doesn't work anymore. HTC patched the exploit.
You'll have to use SunShine S-Off. It costs $25, but is guaranteed to work or you don't pay.
Having S-Off is totally worth $25 IMO.
Here's a link to their website.

Go to this thread. It has a collection of stock backups you can falsh to get back your stock ROM.
It also has a collection of stock recoveries to flash with ADB if you need that.
All the instructions are there.

Firmware is something separate. That link will get you back to stock ROM. Then use Sunshine to s off. After that, you can update your firmware.

The stock recoveries or in that link too. I'm not sure if you need them for sunshine though. Try with custom recovery, if that doesn't work, get a stock recovery.
Or get both ROM and recovery stock, then reflash a custom recovery and ROM.
If you get both to stock, you shouldn't have any issues.

Firmware updates. If you have one fresh out of the box, Firewater would probably still work. And still does for some.

First, I misunderstood your earlier question. Yes the number in front of the backups are for firmware.
To help you more, I'll need some information. Hook up your phone to your computer and start ADB. Then issue these commands:
adb reboot fastboot (wait till your phone boots into fastboot)
fastboot getvar all
Then post what the readout says here, but edit out your serial number (serialno) and IMEI for your own safety.
Then I'll be able to give you a little more guidance.

Your CID is ORANG202 and your firmware is 1.54.73.5, so you will need the backup that corresponds with that.
The backup available was made with TWRP recovery. So you'll need that. (In my opinion, TWRP is a better recovery, less issues)
You could go to their website to download it and get instructions on how to flash it, but there is a much easier way.
Go to the Play Store and install an app called TWRP Manager. Hit the three line menu thingy on the top left, and pick "Install TWRP".
After that go back to the stock backup thread and flash the backup that matches your CID and firmware.

My friend has made a comprehensive guide on firmware and firmware flashing, complete with downloads. Make sure to read the whole opening post so you understand everything. It looks like it might be hard because of his full explanation of the whole process, but it's actually very easy. And very informative.

Can't load my rooted htc one m8 after OTA update

I had rooted htc one m8 with twrp. To be able to install OTA update I have flashed 4.20.531.4. It successfully loaded so I started update. However after reboot it did not go further than htc one sign on white screen. After that I tried following actions without any progress: flash twrp back, delete supersu, factory reset from both stock image and twrp, install previous builds. I can get to bootloader, but my pc does not see it throw windows explorer nor from htc sync manger. I'm stock and don't know what else can I do. Did I actually bricked my phone?

If the screen still comes on, no.
Did you install stock recovery before trying to OTA?

Yes I have installed stocked recovery from t mobile. I changed my cid to super cid. Could that course me a problem? And is there a possibility for me to use nandroid recovery?

Do you mean restore a nandroid backup?
Yes, but it sounds like you already restored a stock 4.20.531.4 ROM, so I don't see how a nandroid backup would make a difference.
Are you trying to issue fastboot commands while in bootloader-fastboot mode? And no response?
