[One (M8) Q&A, Help & Troubleshooting] sebastianbf:
Hello guys

Need your help please. Just got an unlocked HTC One M8 a few says ago. Today I tried to install a Custom Rom (S-ROM) with no luck. Installation seemed to go OK but after optimizing apps the phone just rebooted and I'm stuck in boot now. The phone will not boot and will only get to the boot screen and then turn off. I can access Recovery and TWRP only when plugged into my computer. I have tried cleaning cache, reset to factory default with no luck. Also, I have tried flashing another ROM with TWRP but while doing it it crashes and the phone turns off every time (had tried several roms with no luck) . I even tried to restore a backup I made before flashing the S-ROM but TWRP also crashes while restoring it.

Any help woud be greatly appreciated.

Some info about my phone:

M8_UL_CA (unlocked)

OS 4.16.1540.8

Rooted

S-ON

Radio 1.24.21331147A1.09G

MID: 0P6B12000

CID: 11111111

Thanks in advance

Sebastian

I'm surmising your device is AT&T. You need to flash ROMs that are compatible with AT&T otherwise you get the bootloops etc. Search for AT&T M8 ROMS. And also make sure you have the proper TWRP version.

Thanks a ton Einwod. I'm a total noob when it comes to Android but so far I'm really digging it. I'm also surprised that my device is ATT, I bought it from a Singapore seller in ebay.

How do I exit the bootloop? Should I flash the TWRP made for ATT and go from there? Maybe RUU?

Thanks again

Probably.

Is the AT&T "globe" logo on the back of the phone, or the model number?

These are just a "clue" and not a definitive indication of the version; as we've seen a number of devices that have had their back cover changed in order to "debrand" them.

---------- Post added at 10:10 AM ---------- Previous post was at 10:08 AM ----------

There is no AT&T version of TWRP. TWRP the same for most M8 versions (exceptions being dual SIM and M8 Eye).

More importantly, what TWRP version number are you using?

Hi there! I have the unlocked htc one m8 EU version, it's still in the kitkat (I haven't updated to Lollipop because of the problems that everyone talks about), so I'm still receiving the update notification to this version : 4.16.401.10.

My question is, will I receive the Marshmallow update notification without updating to Lollipop first?

[One (M8) Q&A, Help & Troubleshooting] sebastianbf:
Thanks for the help redpoint.

No ATT globe on the back cover, just a clean cover with no carrier brand. The model on the back cover is 0P6B110 M8x.

As for TWRP I'm using 2.8.7.0
[One (M8) Q&A, Help & Troubleshooting] Einwod:
That information is conflicting with the getvar all output. Your device at one time must have been S-OFF as you have the SuperCID. You may try Sunshine to go S-OFF again. If it doesn't ask for payment and works, then this proves it has been done before. If you go S-OFF again, the possibilities are almost limitless.

I tried it before indeed and it asked for a payment. I can't go S-OFF now since I'm in a bootloop. Any ideas on how to fix this?

I made a backup on TWRD before flashing the custom rom. I have it in a folder on my phone and on my computer (it's not a .img file though) but when I try to restore it using TWRD it crashes in the middle of the process.

BTW what's the latest TWRP? I thought 2.8.7.0 was the latest version.

Alright, I'm a total noob when it comes to modifying HTCs. I've unlocked the bootloader and installed TWRP. I also have xposed installed on my phone.

I just got a notification saying I can download and install Marshmallow! ???

From reading the thread I gather that I need to unroot and lock the bootloader again?

I have 3 questions:

1. How do I revert to stock so that I can update?

2. Will TWRP affect the install of the system? I.e do I need to uninstall the framework?

3. (Most importantly) What do I have to do to keep all my data and apps after I update?

Hi Einwood, thanks for all your help. I run the RUU on a windows machine. Everything went OK except that I'm now on a power loop. I turn on the phone, the HTC and android logo appears for 5 seconds and it shuts off by itself. I can access bootloader but same thing happens, it shuts off while in bootloader options after 5 seconds. Any ideas?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Yes, as I somewhat suspected, its had its back cover replaced to remove the branding.

It further confirms the notion that its a AT&T version, made SuperCID, modified to DevEd software, than back cover replaced to make it a "virtual" Dev Edition.

---------- Post added at 02:58 PM ---------- Previous post was at 02:56 PM ----------

That guide is for another phone (One V). Don't follow instructions for other devices, unless you want to brick your phone.

You don't need to extract and flash stock recovery, before RUU.

Try to run the RUU again.

Make sure to note if there are any error messages.

Post the RUU log, if you can.
[One (M8) Q&A, Help & Troubleshooting] sebastianbf:
Thanks redpoint, but the thing is that since the device shuts off almost instantly it doesn't get recognized by the PC in order to run the RUU again. What else could be done?
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
Leave the phone on wall charger for several hours, and see if you have any better luck. Maybe it keeps shutting off due to low charge?
[One (M8) Q&A, Help & Troubleshooting] sebastianbf:
OK but it actually "reboots" itself too when plugged to a wall charger. I plug it, shows battery icon for 3 seconds or so, turns off, and then again shows battery icon for 3 seconds and so on. It's like a charging loop. I think it's not the battery, since I ran the RUU with full charge on it. Any other ideas?

Deleting the IMEI was for your own protection. You obviously didn't realize this, so now you know.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
The version number is the same, which means its the right RUU for your version.

Even if it was the wrong RUU, there wouldn't be anything to worry about, in that it wouldn't damage your phone. It would just fail to run with an error message, no change to the phone.
[One (M8) Q&A, Help & Troubleshooting] lorah2k:
All this appreciated, but as all this is new to me , and still want to do this myself, so even if my next questions will be stupid, please bear with me.

Does previous suggestion involve saving the update on the SD card, and then from my recovery screen , select Apply from SD card?

Or do I need to familiarize myself with flashing ROMs, etc?

I am still not sure whether my handset is carrier unlocked, code unlocked, rooted or not...:(:silly:
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
None of the above. RUU is an Windows executable .exe program. Connect the phone to PC, reboot the phone into bootloader and select Fastboot (using vol keys, confirm with power button). Then run the RUU program on the PC, and it will walk you through the rest. Its very easy, and pretty self-explantory.

It was modified at one time to make it s-off and SuperCID (CID 11111111), possibly root and/or custom ROM. But its no longer rooted or custom ROM; as you have the "Software official" flag in bootloader. So the previous owner probably returned the phone to stock ROM (also making it unrooted) and changed the bootloader flag to LOCKED.

I can't say whether if it is carrier (SIM) unlocked or not. If you put a SIM which belong to a carrier aside from what the phone was intended, and it works, than its SIM unlocked.
[One (M8) Q&A, Help & Troubleshooting] lorah2k:
Last strike.

Do I need to unlock the bootloader or not?Or the Locked status will not affect what I am intending to do?:confused:

Should I have difficulty with any possible future OTA updates from HTC?

Device is SIM unlocked as it accepts any carrier SIM cards.
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
NO and NO.

If you needed to unlock the bootloader, I would have told you that.

So the RUU didn't work? If that is the case, what are the symptoms? How far did the RUU get, error messages, change in phone status, etc.

You need to be specific in your posts, if you want the proper help.

You mean with s-off and SuperCID? No issue with future updates.

Hi. May I suggest that you return your device to complete stock, take whatever OTAs are available and then flash the desired ROM? The thing about firmware is, your current firmware MAY be enough to run Marshmallow, but there will be subtle differences between the current and new versions. If you go back to stock and take the necessary updates, you will have the latest Marshmallow firmware for your device. Have a look at this very well written and laid out thread. Read from the very first post. All you need should be in the first 4 posts. If you cannot find what you seek, ask the original poster and he will 99% of times find what you require.

Hi guys

Does anyone know how to remove encryption on my M8 Google Play Edition? I've done a factory reset in TWRP and re-flashed the ROM but the encryption is still there. Is there something I'm missing?

Running on Marshmallow (6.0_MRA58K.H9) rooted and latest version of TWRP.

Update: Managed to sort it. Go to TWRP > Wipe > Format Data > Type 'yes' > Then do a factory reset, reboot system and you're good to go with no encryption.

Be warned that you will lose everything! (all pictures, videos, files etc). You literally just have the ROM as if you've just bought the phone.
[One (M8) Q&A, Help & Troubleshooting] EoinCuinn:
Just want to make sure I do the right thing before I do the wrong thing, well more wrong. I flashed a MM rom last week out of boredom, without really considering the firmware side of things. The phone is behaving sort of ok, but it is killing the battery, and my LTE reception isn't brilliant.

What is the best solution, for getting the phone up to Marshmallow firmware correctly? Do I S-OFF it (I am aware this costs, and I have no issue with that, and just flash some updated firmware, or do I follow the nandroid backup restore path and get it back up to MM via the OTA path. I'm presuming the latter is the safer, just more time consuming.

It's been a couple of years since I played in this domain, so I am a bit rusty.

Personally I would go back to stock and take the OTAs as delivered by HTC to get the latest MM firmware and software on the device. Then, if you want, you can flash custom ROM and go from there. Although S-OFF is an easy option, if you do not know what you're playing with by being S-OFF, you can sometimes end up with an expensive paperweight for your desk. Have a look at this thread for going back to stock. It's very well written and put together and all you need is in the first 4 posts.
