HTC ONE M8 Root failed, FACTORY RESET failed, now stuck :/

[dwerp1234]

Soooo....Noob right here :]
I did a really stupid thing, I tried rooting my HTC One M8. I followed the steps, and it worked fine until I flashed and rebooted. After that, the phone was stuck at boot logo, so I decided to just factory reset it, but somehow, after doing that through TWRP, it reboots > went through logo white screen > then stuck at a black screen. I waited for about 20 mins but no luck. What should I do now?

What steps?

There are a few different ways to go about rooting, plus if you don't tell us what TWRP version, stock Android version, SuperSU version, etc. we have no way of knowing what you did, much less how to help you.

so I decided to just factory reset it

Why? Did you read somewhere that this was the proper thing to do for the specific situation? Or did someone tell you? If no to both, don't make up your own solutions or try to guess how to fix things. Its a good way to make matters worse than they already are.

There is no reason to think that a factory reset would fix the issue. There is a common misconception of what "factory reset" actually does. All it does is wipe user data, nothing else. It doesn't replace the ROM, or anything like that.

I'm not sure what Android version my phone is right now (I do not know how to check), the TWRP is 2.8.7.0 for M8, the SuperSU just came with the TWRP, so I just followed the TWPR and got the installer, after that, I downloaded the Root pack or sth like that, but it wasn't automatically rebooting into root mode, so I downloaded the pack and then manually reboot it, after that, it froze on boot logo

I read the factory reset thing on a forum too. Besides wiping cache and data, I wiped the system as well, so there is currently no OS right now, and then planned to download the ROM onto an ext SD card then install it through TWRP. But right now, I still haven't find the proper stock ROM in zip file.

Thanks for your reply, I hope this information helps

No offense, but this sounds WAY out of your league., especially if you don't know how to check your Android version. It's always best to read directions thoroughly first and ask for help before actually attempting to start modifying your device.

You could always try restoring to stock using the specific RUU for your device. I had to do that recently myself in order to get S-OFF.

I'm not sure what Android version my phone is right now (I do not know how to check)

Do you remember if it was on KitKat, Lollipop, Marshmallow?

You unlocked the bootloader by yourself? Is it currently unlocked?

Connect phone to computer, reboot the phone to bootloader, and select FASTBOOT (if not already highlighted in red) using the vol and power keys. Then open a command prompt on the computer and type command: fastboot getvar all

Post the getvar output (delete IMEI and serial numbers before posting).

The output will help tell us the Android version, as well as other critical info to get your sorted out.

the SuperSU just came with the TWRP

Depending on what Android build you are trying to root, the built-in root on TWRP won't work. Which is why we need to know the Android version.

I read the factory reset thing on a forum too. Besides wiping cache and data, I wiped the system as well, so there is currently no OS right now, and then planned to download the ROM onto an ext SD card then install it through TWRP. But right now, I still haven't find the proper stock ROM in zip file.

Deleting the OS is usually not a good idea; and in your situation not a legitimate solution. Even if you were going to flash a new ROM, that process wipes system partition anyway, so no need to do it manually. And wiping the OS before finding the right ROM to flash was also not a great idea.

It might not have made a difference in your case (since you couldn't boot to OS even before you wiped it). But wiping system shouldn't be done unless you really have a good reason to do it, and you understand what the result will be.

I can't count how many posts I've read (and helped) that stated along the lines of "I wiped system and now my phone won't start, please help".

Hmm, thanks for that link, my Android is 5. Lollipop, I just get so confused with all the numbers on bootloader...How do you get S-OFF though? I've been trying to do that, but found no answer.

 

[dwerp1234]

My Android is indeed unlocked, I followed the instruction on the internet and got it unlocked.

For the wiped system situation, I followed the instruction on a website on how to install stock ROM, but I'm stuck on finding a stock ROM myself, and I thought deleting the OS wouldn't make any difference.

What websites are you going to, and why? Everything you need to know about rooting can be found here.
Download this onto your PC. It's an RUU for your model and firmware version. Also, it's a direct download link, so don't click it on your phone.
After the download is finished, hook your phone up to your PC. Get into fastboot, and enter fastboot oem lock. This will lock your bootloader, which you will need to do since you are S-On.
After that, double click on the download and follow the prompts.
This will get you back to your stock state. Unlock your bootloader again via htcdev.com, use fastboot to flash TWRP2.8.7.0, then use your new recovery to flash the latest SuperSU update.zip, or simply flash a rooted ROM with that same recovery.
That's it. Fixed phone and rooted.

Thanks for your answer. If you don't mind me asking, but what is the latest stable SuperSU for my version? Is it 2.65?

Edit: After I tried to run the ROM Update .exe, it ended up with an error: ERROR [170]: USB CONNECTION ERROR, although I already connected my phone and it is currently stuck on boot screen as always.

 

[redpoint73]

Thanks for your answer. If you don't mind me asking, but what is the latest stable SuperSU for my version? Is it 2.65?

As you are still on Lollipop, any SuperSU version 2.44 or up should be find. I think 2.46 is the latest version still labelled as STABLE.

If you were updated to Marshmallow, you would need 2.62 or higher. Those are labelled as BETA, but folks have been using them with no issues, in my understanding.

On boot screen, in fastboot mode (with fastboot highlighted in red)?

You were able to do fastboot getvar all, so I assume "yes" to the that question. So in that case, the RUU can be very finicky. Try re-installing HTC Sync, different USB port, different cable.

You might even need to try another PC. Win7 and USB 2.0 (USB 3.0 is known to cause issues) are your best bet to get the RUU to work.

Thanks a lot, I changed the port and it runs fine. The ROM is being updated right now. It says it will take 10 mins, but it has been 40 minutes and still 0/6. I'm using win10 btw. I have no win7 around.

You have connection issue .. I'm on Win 10 64-bit and no problem when running RUU.

You need to use USB2.0
Latest HTC USB driver installed - Install HTC Sync Manager - http://www.htc.com/us/support/software/htc-sync-manager.aspx
it will install the needed drivers then uninstall the HTC Sync Manager but leave the drivers.

And I always see many people with USB connection and unable to run RUU ... that's why we have nandroid backup to restore to stock.

I tried to root my device and it didn't work properly and now it is stuck in the boot logo "that white screen with green hhtc on it". I was runniing on marshmellow and twrp version 3.0.2.

Here all you need is in this post follow the instruction and you will be back to stock be aware that your internal storage will be wiped
http://forum.xda-developers.com/showpost.php?p=64926626&postcount=6

after that if you want to root your device flash the latest twrp then flash the latest supersu.zip ( 2.78 SR1 )

To be clear, factory reset doesn't revert anything back to stock, aside from (all it does is) wiping user data.

The error message "cannot load" means the file isn't in the right place. You need to put the unlock bin file in the same folder which contains fastboot.exe (and where you are executing the command from).
