[One (M8) Q&A, Help & Troubleshooting] redpoint73:
If no charge LED (try charging overnight - try various button combos with and without charger attached) and qhsusb_dload, you are likely bricked and need JTAG. What you flashed may have overwritten the partition table or hboot.

This is the reason you have to be

extremely

careful about what you flash if s-off. S-off means no device check, and you can flash something intended for another device that bricks the phone.

Need some help here

Heyy there, I'm a newbie

please, help me... :(.

My phone won't turn on anymore after i charge my m8 for a one night. The charging LED is orange but the phone won't turn on anymore, i've try charge for a half day, but it's nothing happen. Also my PC won't recognize it (maybe cause i dont enable usb debugging). My phone is no rooted, just standars user. I tried Vol Up and Power / Vol Down + Power / Vol Up Down + power , nothinig happens. I hope someone can give me help, any help will be awesome.

Changed Kernal Settings...

My VZW M8 will not boot. I installed a Xposed mod called "Xtended Settings" and changed the kernal settings and the phone immediately rebooted and shutdown 5 seconds later. I can get it to power on using power+vol up, but it shuts down 5 seconds after every time. I can't access the bootloader using power+down or adb. I do not have a charging light when plugged in to either computer or outlet. I know I'll be fine if I can get into the bootloader, I just can't get there. Thanks in advance. I'm running CleanROM 2.0 with 4.4.3 firmware, TWRP recovery.

Hello exocetdj,

Have you tried RumRunner? Otherwise you should try Sunshine. I know Sunshine isn't free, but it does work. I have a Verizon HTC One M8 that Firewater would not S-OFF, I tried Sunshine, and it did the trick :) Another nice thing about Sunshine is, you don't have to have root to run it (it roots itself). Good luck!

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
If your screen comes on, and still can boot recovery; you aren't remotely bricked. You just can't boot into OS, and of course if OS (system ) is wiped that is going to be the result.

Just restore your nandroid if you made one (if not, why the heck not - see now why you should?).

Otherwise just flash a ROM, adb push of adb sideload to the phone if you need to. If the phone still doesn't boot, fastboot erase cache and re-install recovery by fastboot (or try a different recovery or update to the newest version).

May have deleted recovery

Hi, I was wondering if you could help me:

Today I attempted to root my phone via Hasoon2000's All-in-One HTC M8 Rootkit, and I'm not really sure what went wrong. I successfully unlocked it, but after trying to flash a custom recovery, the adb command window got stuck on "sending recovery..." and my device was frozen in fastboot mode. After waiting a while, I rebooted my device, and the OS is fine and everything works. But now I'm afraid I may have deleted my stock recovery in the process. I attempted to boot into recovery to check, and all I got was the red triangle. What can I do, and how can I confirm that I have an actual working recovery?

Thank you in advance!
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
You have an actual working recovery. Red triangle is stock recover! I think you press the vol up button to display the recovery options.

Just fastboot erase cache, and install the latest TWRP with fastboot. The one included in the Toolkit is something llike 6 months obsolete.
[One (M8) Q&A, Help & Troubleshooting] acarter264:
Ok, it wasn't really showing any options, just that red triangle, but if that's what stock looks like, that's fine! Thanks!

I think I might back off at this point... I wanted to root so I could use BBS and Greenify, but I really don't want to risk ****ing up my phone. Plus I don't want it to be difficult to get Lollipop when it comes out.

Hey,

I could get a M8 from a friend that was all messed up. It was in a bootloop. I managed it to get CM on the device but that's it. It works but it has an older firmware so I have no 4G and wifi is not so stable.

I have read a lot about going back to stock but I'm scared that I will explode/kill/nuke the phone.

So if you have a bit of spare time I would appreciate it a lot. What information do you need from me?

S-on and unlocked bootloader.

Help!

my phone is not coming on and when i press power and up volume, the google image flashes and then it goes dead again. I have tried loading into bootloader but it doesnt work

I think the issue was caused by trying to flash the 4.4.4 update with an incorrect build.prop file.

The phone was converted to a GPE and all worked fine. I then got the 4.4.4 notification and proceeded to stock recovery, but it errored out and mentioned something about a chnage to the build.prop file. So i assumed something had chnaged and looked online for a different one. I found one, re-flashed but got a different error (dont remember) and then clicked on the reboot option.

Ever since then, phone has not come on. Help please
[One (M8) Q&A, Help & Troubleshooting] redpoint73:
What happens when you try power+vol down to go to booloader?

Or if you have adb setup: adb reboot bootloader

or: adb reboot recovery

If the screen comes on at all, you are probably not bricked. Just need to get into bootloader and go from there.

---------- Post added at 10:44 AM ---------- Previous post was at 10:39 AM ----------

If your CID and MID match the file, it should be okay. Also, you need to come from the main and hboot version directly before the OTA that you want to flash, or version check will fail with s-on.

With s-on, there actually isn't that much to be scared of, as the worst that will

probably

happen is that a check (CID, version, etc.) fails and the install aborts.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
adb can be a savior in these cases.

adb doesn't need a working OS to talk to the phone. I think as long as the bootloader works, so will adb. That is one of the things that makes it so handy when trying to recover!

[One (M8) Q&A, Help & Troubleshooting] zoopenguin:
Indeed, it failed, tried your tip and followed the Google conversion thread but it did not work probably because the device is S-on. I'm thinking that device already had S-off before because I found something very weird in the /devlog/recovery folder.

Hi Matt,

This is the first time that I have come across someone offering the same kind of service that you're offering so I must really commend you on that. If you end up fixing my problem I'll be more than happy to provide a donation towards your hard work.

My Problem is as follows:*

I recently got my hands on an M8 and rooted it with Hasoon's All in One toolkit after unlocking the bootloader and flashing 2.7.0.2 TWRP. It has worked fine so far until I one day somehow landed in HBOOT mode by accident and noticed that nothing was written next to OS. I booted in fastboot and tried the getvar version-main command and nothing was coming up.

I read some threads on XDA that said it could have been the TWRP so I flashed a new version, the latest 2.8...something. Still did not solve the issue. I then proceeded to flash Philz recovery and that also did nothing. I am now worried that if something happens to the phone or if I need to flash stock recovery for OTA updates that I wont know which version I'm dealing with. Can you help me get back my version details please?

As far as I know, my device's details are as follows:

HBOOT version: 3.19.0.0000

Radio: 1.21.21331147A1.19_2G

OpenDSP-v46.2.2-00564-M8974_FO.0811

Software status: Modified

*UNLOCKED*

M8_UL PVT SHIP S-ON

CID: HTC__621

Software version: 3.28.709.5

Thanks
[One (M8) Q&A, Help & Troubleshooting] xunholyx:
Your software version, DSP, and hboot tell me you are the latest firmware, if that helps.

My OS was blank before as well. It's nothing to worry about as far as I know.

But software version is what you will be looking for.

Actually, my hboot doesn't even have "software version", just OS which should be the same thing.

With root, yes.

[One (M8) Q&A, Help & Troubleshooting] redpoint73:
If the screen comes on, and you can't get into bootloader, it means you are just doing the button combo wrong.

Hold power + vol up for several seconds to force a reboot.

The moment

the screen goes dark, let go of those buttons and just hold vol down and

don't let go of it

until the bootloader comes up. If you see the HTC boot screen instead of bootloader, you either didn't start pressing vol down fast enough, or let go too early.

And did you just flash the hboot, or the entire firmware package? By firmware package, I mean a firmware.zip that contains hboot, radio, WiFi, Bluetooth, and other modules. Its the entire package you need to install for ARHD21 to work properly.
