[Solved]Software Brick or Hardware?

Hello,
today my phone freezed in the Notification panel, while i was checking a new mail.
Then I have performed a "battery pull" with Power and VolUp, since that the screen is black.
The last thing i has done before, was to install the Xposed Framework over the installer App.
The strange is that the phone seems to boot and I can connect to the PC.
I have access to the device via adb and fastboot.
It is possible to boot into the Bootloader and even in Recovery (TWRP).
I can't believe that the Screen is dead after a Software freeze, that would be a strange coincidence.
The last 10 hours i have researched the internet for a solution, without success.
I have found this Thread, but no way to restore a nandroid without access to TWRP GUI, because of the black screen.
http://forum.xda-developers.com/showthread.php?t=2715901
I tried to reflash the original firmware, erase cache and to reflash the Recovery,
but the Screen remains black.

I saw that topic, but thought that would be a service where you have to send it to the UK.
I've checked the Thread again.
Thank you for Reply!

the only thing I can think of is the RUU, I dont know if it will work on an unlocked bootloader :|
im not sure if there's an RUU already for the m8.
hope someone can provide a better solution

Yes, I have full accsess via adb and fastboot and the System boots up.
Flashing the Stock Firmware.zip that matches the Rom, which is posted at xda, was one of the first things I've done.
Now I'm looking for a way to return it to Stock, since RUUs are not available at the Moment.
Any Ideas?
Best Regards, Toni

Ok, since the system boots up,i could check my M8 with:
adb shell screencap -p /sdcard/screen.png
+
adb pull /sdcard/screen.png
It is working, so it is no Software Brick.
The Screen is dead, but fortunately the Touch is working.
In the next step I copied my own Stock Nandroid 1.12.401.17 to the internal SD, to /TWRP/Backup/SHXXXXXXXXX.
Then I've managed to restore the Nandroid, blinde with my M7 beside.:fingers-crossed:
Now the M8 is Stock with 1.12.401.17 and 1.54.401.5 Firmware.
Which Stock-Recovery I have to flash, for 1.12.401.17 or 1.54.401.5, or it dosen't matter at all?
->I've Found the answer in the FaQ in this Thread:
http://forum.xda-developers.com/showthread.php?t=2701376
I've figured out, that it is definitely a hardware failure of the display.
With the ADB screencap I was able to operate the device over the touch.
In this way I was able to reset it completely back to stock, including Locked Flag (probably).
Now it's on the way back to the distribution company.

Help to install official rom 5.0.2

Hello everyone,
i am having a problem with my M8. I have installed CyanogenMod 12 to my phone and i want to go back to official 5.0.2 ..
The problem is that I have no wifi signal with many roms i tried to install. So i want to go back to official.
Thanx in advance ..

You have old hboot and firmware version.
All the newer Sense based ROM require hboot no less than 3.19.0000
What's your fastboot getvar all - post here minus serial no. & imei no.
This will help to go back to official and maybe lollipop already available for your device region.
and it's 5.0.1 not 5.0.2

Some help here ?
Installed HTC driver and Htc Sync my still says no device found ..
Win 8.1

Your drivers are still not installed. Go into Device Manager and get them installed and it'll work

You also need to "allow USB debugging" in developers options on the phone. You can check whether your phone is actually connected by typing "fastboot devices".

No you don't as ADB is for when Android is running, fastboot is when in the bootloader

ok i managed to connect it to HTC SYNC MANAGER.

Your wifi isn't working because you have outdated firmware. 3.16 hboot = 4.4.2 firmware. You need to update it.

No need for a tutorial., HTC__203 is your CID. That's WWE (France). Download this RUU onto your PC, and run it. It's an .exe file, so all you have to do is download it, double click it, and follow the prompts (just like installing software on your PC).
Put your phone into fastboot before you run the download, as sometimes there are problems flashing when you haven't already booted into it (from what I've heard).
Also, back up anything that is important to you, as this will wipe your phone.

m8 won't factory reset, need stock rom or something.... please help

Hi there, I am hoping someone can help me, and make things easy to do cause I am tired of traulling through page after page of failed attempts. So a little background first....
My M8 started coming up with an error to do with google play services not working and it crashing repeatedly, after trying everything under the sun to fix the issue, I decided a factory reset was best. So I attempted to do a factory reset from within the HTC. it seemed to do nothing. So I got in to the HBoot menu and that just goes round in circles. Last time it did something silly like this I had to send it off to HTC for repair, I dont fancy losing my phone for 3 weeks AGAIN, so if someone here can help, I would be very grateful.
I did a "fast boot getvar all" to retrieve the following

Its a UK phone, locked to the EE (orange) network. I've tried various zip files on the SDCard to do the factory reset but it normally comes back with FAILED.
Can someone, anyone, help get the orignal stock ROM and what I need to do to get it to work....... its annoying that HTC didn't reflash the rom on the phone and they arent answering phones or email or their "live chat"
thank you in advanced.

One thing you should understand, the term "factory reset" as done in Settings or stock recovery, is a misnomer. All it does is wipe user data. It doesn't restore or affect the software in any way.
By "various zip files" I believe you mean RUU. But you can only run RUUs with the proper version number, and for your CID. Without nowing what zips your tried to run (full file name and/or version number) or what error messages you got, I can't say for sure why they failed.
I don't think your version has RUUs, but if it did, RUU for version 6.12.61.4 is what you need.
Otherwise, you may need to unlock the bootloader, flash custom recovery, and install the stock nandroid 6.12.61.4 from the following thread (with more instruction on how to do so): http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

Meaning it won't stay in fastboot mode (reboots)? If so, that can be a problem.
If so, are there any messages on the screen about trying to install a file, before it reboots?

wiped my OS, flashed a poop ROM need help

Long story short, I forgot my screen lock and wiped as a last resort. Realizing too late that a factory reset wouldn't complete, I was left with a paperweight. I was able to get a rooted stock ROM from XDA, flashed it and it seems to be working. I want to get back to viper ROM, preferably marshmallow (I'm currently on lollipop) but I am having a lot of trouble. Attempts to get s-off have been thwarted, and flashing viper (5.0.2) has failed. Any help would be appreciated. I can answer any questions.

What stock ROM did you flash, exactly?
How exactly are you trying to s-off, and what step did you get stuck (error messages, or other results?)?
When the ROM failed, did it give you an error message (or list any other outputs or results)?
Your statements on these last 2 points if far too vague, for us to help properly.
Also, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

Lmy470.h6 is the ROM I flashed. I've been trying to push firewater via adb to get s off. I can't/won't pay for a sunshine. When flashing other stock Roms, the error is no error. It just says install aborted. When trying to flash viper, it says there's a permission error. When trying to run firewater, it gives me the PIE error. Getvar coming later.

Firewater won't work, Period. It had an online component (had to connec to a server), which the devs stopped supporting in Dec 2014. Nothing you do will make it work, and is a complete waste of time.
That said, you don't need s-off to flash ROMs. And whatever is wrong with flashing ROM, s-off is probably not going to fix.
The fact that multiple ROMs work, indicates user error, and you're incorrectly trying to blame the ROMs ("poop ROM").
What TWRP version? Need that info, and getvar data. But I'm guessing you just have an old version of TWRP (or try another slightly different build TWRP).

I'm actually using philz touch recovery. I only call it a poop ROM because I don't like what it came with and how it looks. Also. The ROM I'm using is the only ROM that works thus far. Most other Roms simply abort. Viper ROM tells me it doesn't have to permissions necessary which indicates the need for s off. I attempted getvar, however the command window just sat idle and wouldn't let me type anything. Am I missing something there?

I should also mention I've been using recovery to flash Roms. Perhaps flashing via adb would work better? Or work at all?

One last thing. Flashing the ROM I'm currently using created new 0 directories. I now have 0/0/0. Any safe way to fix that?

That's the problem right there. Philz hasn't been updated in a long time, maybe 2 years. Its almost certainly the cause for the ROM flashes failing.
Use TWRP, but exact version depends on your current firmware version, indicated in getvar. But probably TWRP 2.8.7 since you indicated you were using Lollipop ROMs okay.

So its your personal opinion and preference, and I would recommend you not insulting the work of devs that work so hard (usually for no compensation) to post their work here.

Sideload adb still needs the proper recovery, adb can't flash a ROM by itself. Sideload just adds move points of failure, not less. I don't recommend it, as I've seen it cause more problems than it solves (fails when simply flashing in recovery works).

Are you in bootloader-fastboot mode when issuing the command?
If so, try another cable, another USB port, or re-install HTC drivers.

I haven't been I boot loader mode. Will try shortly. Also. Will change to twrp. And yes, I'm on lollipop 5.1. I will change recoveries and attempt getvar. Results will be posted.

I'm glad I asked for the getvar data. Your firmware (hboot, radio, etc.)is woefully outdated as its still on kitkat firmware, which I can tell from the radio number and version-main 3.28.1540.5. This alone will prevent LP and MM ROMs from working (no boot or broken WiFi).
There are various ways to update the firmware:
- Restore stock TWRP backup for 3.28.1540.5, and corresponding stock recovery, and perform OTA updates which will also update the firmware.
- Relock bootloader, and flash full stock 6.12.1540.4 firmware following the Method 2 here. After flashing firmware, you can then unlock bootloader again, flash TWRP and flash the desire ROM.

I would greatly prefer not to relock my boot loader,as it requires HTC correspondence to unlock. That could take a while. Can you walk me through your first method? Possibly with links to other threads and downloads?

I messed up. big time. So i found and downloaded your recommended recovery image. Downloaded flashify for root, and flashed the image. Now whenever I try to boot, or enter recovery mode, i get the red triangle of death. Please help! I tried reflashing twrp via adb, but adb doesnt recognize my device anymore! I dont know what to do...

update: performed a factory reset. Was able to get device up and running again. Impatiently awaiting further instruction.

What did you download, and from where? Its not clear what you were trying to do here, exactly. You don't need root to flash ROMs or TWRP backups; and I personally dislike using apps like Flashify, for things that are easily accomplished with fastboot, TWRP, etc.

I found the stock nandroid backup suggested and flashed it using flashify. I have an idea what needs to be done here, but if an expert like yourself could leave me some detailed instructions as well ad download links it would really help.

He did give you expert advice, and you didn't follow it. Don't use Flashify. Any instructions you get from anyone here will tell you to use ADB/fastboot.
Also, you are going ahead without proper instructions and you can go ahead and do that, but go to where you got those other instructions from to ask for help.

Actually, in reference to the nandroid backup, he (we are assuming here) never said exactly how to use the files. Just what to do. I need precise instructions with links to fix this issue. This is one I've never dealt with before.

Quick M8 FLash question

Friend of mine asked me if i could help him with his M8 which seems to have software issues.
The phone boots untill the point when it says Installing Applications 1/160 or something similair. It will never reach the end because it reboots after a while and starts all over again.
The simple question is: Can i flash stock firmware while de bootloader is locked and s-on?
(I'm able to enter download and recoverymode)

Simple answer is yes.
The hard part is whether the stock RUU is available for that device version or not.
If firmware only which is part of RUU is much easier to find.

Where can i find the right RUU?
fastboot getvar all

Is the phone modified (unlocked bootloader, custom recovery, root, custom ROM, etc.) or is it fully stock?
Do fastboot getvar all, and post the results (delete IMEI and serial number before posting) so we can see details about the phone, and possibly advise if there is an RUU to restore stock ROM, etc.
Asking for stock firmware is probably not really what you mean to ask. I've replied to a similar request here, which will explain the difference (firmware versus ROM or RUU): https://forum.xda-developers.com/htc-one-m8/help/return-to-stock-firmware-t3683082
EDIT: I posted the above at almost the exact same minute the OP responded with getvar output. Thanks for posting it, and I will look into it right now.
