HTC One Won't Start Up - One (M8) Q&A, Help & Troubleshooting

So I was running a custom ROM for a while and decided to switch back to the stock ROM. After doing that, I flashed the stock recovery so that I could install the OTA update from version 4.28.502.2 to version 6.20.502.5. During installation, the phone got stuck in a bootloop, so I wiped the cache and tried to start it again. After that didn't work, I factory reset it (in the bootloader, and then in recovery after it didn't work), and it still doesn't work. ADB and fastboot doesn't detect my device even though I had USB debugging on before I tried to update it (I'm guessing that the factory reset disabled that?). I can access the bootloader and recovery, and my phone has an unlocked bootloader with S-On. I have the AT&T HTC One M8 if that helps. Can someone help me please?

Hi,
Can you go to boot loader and then connect your phone into your computer after that you flash the recovery like TWRP, wipe all the data and reflash your rom, you can find it on XDA. After that you have to find the correct recovery for your device (see the website of Mike1987), find the correct recovery for your device and then flash the stock recovery and it have to work. Waiting for your news.
Have a nice day

I'm saying that my computer doesn't recognize my phone, and that's why I can't flash a custom recovery like TWRP

Have you got the right drivers installed, have you tired another hub ? Is your battery fully charged ?

Yes, I have the right drivers installed. Yes, I have tried a different USB port. Yes, my battery is fully charged.

Try to uninstall the drivers and download the HTC drivers, fastboot and adb from Internet and try again. Do you have another PC? Because one time i have got the same problem than you and when i take another PC it's worked.

The drivers fail to install everytime, and I've tried on three different PCs

Your problem is not the phone cause it detected by the PC but the drivers failed to detect you HTC. Can you say if you boot your phone in the boot loader, the phone show you if is in boot loader connected by usb or not?

In fastboot on the phone, it shows that it is connected with USB, but ADB says that there is no device connected

adb won't work on bootloader/fastboot mode. Only fastboot does.
When on fastboot, type command fastboot devices, do you get your device serial no. ?
On bootloader/fastboot, what is x the OS-x.xx.502.x now ?

I followed the instructions in that link, and everything works perfectly now. It's updated to 6.20.502.5. Thanks

Seems like your main issue was not properly using fastboot mode for fastboot, and realizing that adb doesn't work in bootloader mode? That, and having the proper firmware and RUU files.

[Q] Stuck in boot loop

Hi there
Hears my problem, I install a new rom today HD rev 12
The problem is that I think I had USB problem installing the boot img. Now the phone just keeps rebooting
I have tried CWM and the recovery boot option but still no good ,I have used all the CWM recovers still no good I think the problem is the boot inmg didn't load, but because I can't get the pc to see phone, error meassage mtp driver not installed I can't reload the boot img at CMD
Any help out there...
Many thanks
If you are having a problem with bootloop you need to reflash boot.img with the ADB tools and clear cache.
You don't need CWM for that. If you can't connect your device with USB to your pc you can try to restart your pc.
In ARHD thread everything is explained very clear, I think Mike even has a batch to flash boot.img

Boot loop
Hi and thank you for your reply,
I have rebooted serval times and still no good, the best I ge is if I go into CWM and then my pc can see the phone as a removable drive I:
But I can go no further than that when I go into fastboot I can see error about USB master failed. So I don't where to go with this, if I can get the USB to recognise the phone it would be easy to just re install the boot img, I have unistall the USB drivers. ECT but still no good.
Also if I'm in fastboot and look in device manager I can see andriod USB devices and my HTC listed there....

that's not fastboot, that's the bootloader... unplug the phone, boot it in bootloader still without micro usb, select fastboot and then connect the phone to usb...
Hi sorry about that
I have tried that and I even get the sound of the USB being connected but that's it, you don't see the htc drive in devices
I try using the ( install boot windows ) and I get the error can not load boot img and if I re boot the phone just keeps looping.

stupid question but, have you got HTC Drivers installed? https://docs.google.com/open?id=0BwkK3Wt9IXrgRm5wRGhJVVB4YjQ

Hi Mike,
If you get the sound USB is being connected it's ok.
Next you need a folder with the ADB Tools and place ARHD V12 boot.img into that.
I've attached the tools.
Download, unzip it and place boot.img in and connect your device in FASBOOT USB
Now open the folder.
To make it easy I've placed a CMD shortcut in it, klick on it to open the window.
Type the following:
fastboot flash boot boot.img [enter]
fastboot erase cache [enter]
That should do it, you can now reboot.

If you are able to boot into fastboot, search the latest TWRP and flash it via adb. Connect your device while in fastboot mode and see if it recognize it.
If it does put the recovery file you have downloaded on your desktop and open a command window, press shift and right click at the same time and click on Open command window here.
Type adb devices, if you see a serial number go on and type adb reboot bootloader, then type fastboot flash recovery [ the name of the recovery file you have just downloaded ]
You can do this just by powering on your phone, no need to be already in fastboot mode, just follow the commands.
Press shift and right click : open command window here : adb devices : adb reboot bootloader : fastboot flash recovery [ the name of the recovery file you have just downloaded, do not forget the .img extension ]
fastboot reboot
Once you have a working TWRP you can flash your corresponding backup and go back to stock. The backup will be flashed from TWRP, search for instructions.

http://teamw.in/project/twrp2 and click on the upper right Get TWRP for your device.
Choose your device recovery and download the adb version. That is the .img
Once you have downloaded TWRP put it on your desktop.
Connect your device with your laptop/pc with the unknown sources checked also the usb debugging checked.
Move your mouse over a free space on your desktop, click once just to be sure there is no app or file clicked.
Then press shift and keep it pressed while you right click your mouse.
Press open command window here
in that command window type : adb devices
if you see a serial number type : adb reboot bootloader
then type : fastboot flash recovery openrecovery-twrp-2.8.1.0-m8.img
fastboot reboot
openrecovery-twrp-2.8.1.0-m8 : This is an example, you will write the name of your recovery but it should be pretty much the same.
Good luck.
Are you familiar with
adb/fastboot commands?

You say "pushing a ROM" with what?
You don't push a ROM with TWRP you just flash it.
Or are you talking about pushing the ROM with fastboot?
If you have TWRP than download a stock backup and flash it.
Take a long look at my profile man and if you look just right you will see I've done and asked some stupid things in my travels here on XDA.I can tell you I remember every phone and ridiculous thing I've done to each of them,I still feel crunchy when I think of the mistakes.

If you can't remember what you did, or at least even try to list in detail the steps you did as best you can remember; it makes it very hard for anyone to help.
Saying you followed some tutorials on an entire website (3 websites actually) doesn't tell us jack, and isn't any better than telling us nothing.
Its not even clear the current condition of the phone. Your OP says TWRP doesn't work, then a later post says you are trying things with TWRP, so presumably you have TWRP. But since you never stated that, we can only guess.
What happens when you try to adb push or sideload? What error messages, does it make the phone reboot, stuck on boot screen, etc?
TWRP working? Bootloader is unlocked? If yes to both of those, you should be able to just adb push a ROM, or put one on removable SD with a card reader attached to your computer. Than flash the ROM in TWRP.

I recently decided to root and install a custom rom on my old stock sprint HTC one m8. I unlocked the boot loader via HTC Dev website. I then flashed the TWRP recovery. Since doing the latter step, it's been booting into fast boot all the time! Did you ever figure out what was wrong with your phone?

You only flashed TWRP onto the phone? Or did you root also?
Not nearly enough info to provide the proper help.
Please do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

What version SuperSU did you flash (if you got that far)?

[q] htc one x stuck at fastboot while installing arhd rom

Please help , ITS VERY URGENT...
My HTC ONE X is rooted unlocked and S-OFF
I was about to install ARHD latest ROM. I went to flash boot.img first.
The moment I clicked on "install-boot-windows.bat" in FASTBOOT USB mode, everything just froze.
No button works. My computer gives a message of " USB DEVICE NOT RECOGNISED" .
When I try to give any command from Fastboot or ALL IN ONE TOOL KIT, IT SAYS " waiting for device" .
My phone is stuck at FASTBOOT USB screen.
please help as fast as possible. I can't wait for my device to die.
I am attaching the snapshot of my current phone screen...
When I type "adb devices" , it doesn't show any device
when i type command " adb reboot recovery ", it says device not found.
Now what to do??

But then , How do I flash boot.img for ARHD ?
Since I had followed all the steps properly and in sequence.
When I tried flashing boot.img from my laptop previously, my device crashed and then no button worked . My laptop kept giving a message that USB DEVICE NOT RECOGNISED .
Also, unless I flash boot.img , how can I flash the ROM?
Do you have any link or clue?

you can flash the boot.img with the command fastboot flash boot boot.img Try on different port or install latest htc drivers. You can flash official rom with RUU download RUU reloack the bootloader and run the RUU then you will be complete stock ROM.
Any link for what, I give you a clue in my 2 post.

The only problem is that my laptop doesn't recognise my phone. So commands hang and my phone freezes .I have tried all the ports while deleting HTC SYNC , installing different drivers from so many different sites/posts one by one . Finally was able to reboot the phone . I will give it a try with another laptop or using a different datacable . Unless my laptop recognises my phone, properly , I don't think any command will work.

I have messed up, I don't know where to turn. HTC One M8 softbricked in Bootloop.

I have an HTC One m8 that is stuck on Bootloader. It is an unlocked bootloader with S-Off. I had CWM but I installed stock recovery back onto the phone before flashing a stock kernel (I was trying to make the phone look untampered with before I turned it over to my provider), the Kernel came with a sha1 and was from a trusted website and I am 100% sure it was the right compatible Kernel I'm pretty sure I just had a bad flash.
I have tired the following to get the phone past the bootloader:
1. Fastboot USB Mode --> Try to get ADB to recognize the device --> Debugging mode isn't on (obviously) --> ADB can't recognize the device.
2. Use AndroidSDKSlim/ Android SDK tools / Android Utility to remotely turn on Debugging mode (I got nowhere with this)
3. Attempted to use PdaNet to remotely turn on Debugging mode (got nowhere)
4. HTC Sense doesn't even know whats going on
I just need to get TWRP or CWM or litearlly Any recovery installed. That's all I need, I can do everything from there. I can't remotely install a recovery via adb because adb can't recognize my device because I can't turn Debugging mode on because my device is softbricked!!! Gahhhh. I haven't been able to come up with a way to remotely enable debugging mode or to get adb to recognize my device.
Any ideas/comments/suggestions would be heavily appreciated - I've resourced from every relevant thread I could find. Posting here was a last resort I try to fix things on my own but I'm too many days into this with no results please anybody.
ADB won't work while on fastboot mode. ADB only while in recovery or on OS running.
You don't need USB debugging on for fastboot
fastboot devices - see whether your device is listed with serial no.
if yes then run
fastboot flash recovery NameofRecovery.img

Thank you for reply!
I have not been able to get ADB to recognize the device, which is pretty much my whole issue right now. It does not appear under the devices list. If I can just get adb talking with my phone everything else should be easy, I just can't figure out why it's not recognizing it.

4. HTC Sense doesn't even know whats going on
I just need to get TWRP or CWM or litearlly Any recovery installed. That's all I need, I can do everything from there. I can't remotely install a recovery via adb because adb can't recognize my device because I can't turn Debugging mode on because my device is softbricked!!! Gahhhh. I haven't been able to come up with a way to remotely enable debugging mode or to get adb to recognize my device.
Any ideas/comments/suggestions would be heavily appreciated - I've resourced from every relevant thread I could find. Posting here was a last resort I try to fix things on my own but I'm too many days into this with no results please anybody.

1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears again (Should be around 10 seconds), press the volume down key.... Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.
4) Once you are in the bootlader, select select fastboot by pressing power key.
5)you can flash either permanent or temporary a TWRP recovery once you are in fastboot.
6)Once you are in recovery mode, you can transfer any custom rom to memory or sd card, then install it from the place you chose.
7) you can flash RUU file at fatboot mode as well.

Stuck in TWRP and fastboot not working

Hello. I decided today to clean install the Pixel Experience 10 rom. I previously had a Pixel Experience 9.0 Pie. I did the following:
1. Booted into TWRP and selected Format Data
2. Everything is deleted, so it's time to flash a new rom. The guide says to go Advanced/ADB sideload and enter a command.
3. Command is not working. My phone is connected to the computer but it's not recognized. I can't even manually transfer it to the phone so i can install it via TWRP.
So i enter fastboot. Phone is recognized. When i type fastboot devices i get this:
Code:
C:\adb>fastboot devices
42abad9b fastboot
If i try to flash again a TWRP, my phone disconnects and it asks to reboot the phone by pressing a volume button. And i am stuck here. Nothing i can do. Any suggestions? I haven't done anything unusual. I am truly desperate. Any help will be appreciated.

Hi !
Did you bypass ARB with dummy.img before you flashed TWRP?
Do you use win 10, if you are change usb or use usb hub. If that doesn't help use win 7.

Good luck and stay safe.

I already had TWRP from long ago. And i didn't even try to flash a new ROM. I just formatted Data. I have the TWRP version 3.3.1-0. But as i said, PC does not recognize phone in TWRP and i can't adb sideload any ROM because of it.

Go back to previous version of TWRP(latest is buggy) or use OrangeFox recovery.
But still if you lose custom recovery you need again start over and bypass ARB.
And check if your bootloader is still unlock.

I can't go to a previous version of TWRP. I can't flash any recovery via fastboot because of the problem i said at the first post. I somehow managed to boot into some previous versions of TWRP via a tool called TOOL_ALL_IN_ONE, but nothing changed. I had the same exact problems.
How will i check in my current status if bootloader is still unlocked?

Use this and post the result...
Code:
fastboot oem device-info
So you managed to get TWRP via TOOL_ALL_IN_ONE, ... when you are in TWRP flash TWRP again via TWRP or better flash OrangeFox Recovery(use SD CARD or adb push - for more info google it for adb commands), than reboot it directly into recovery again by TWRP option reboot to recovery... and now you can flash your ROM.
So make it simple
1st time you'll boot in TWRP by TOOL_ALL_IN_ONE,
than you'll flash recovery via TWRP and make it permanent,
Than you'll directly reboot to recovery via TWRP,
now you can wipe and flash your ROM.
Happy ending :highfive:
The problem was that i couldn't use ADB sideload because the phone wasn't recognized by the computer. And i fixed it in a very weird way, by connecting the phone to the PC monitor's USB hub and that way the phone was discovered by the computer. So i fastbootted the latest TWRP and then easily transferred the ROM i wanted to flash via TWRP. It's crazy that i spent all day just to connect the phone to a USB hub so it could work...
