HTC One M8 - Soft Brick / Black Screen

I tried installing some customs ROMs but decided to go back to Stock using a backup but I must have backed up incorrectly as now my phone won't boot into an OS.

 

My phone basically is doing this:

 

(Not my video)

 

 

 

I'm completely lost with what to try next, I've tried to use the AIO Toolkit to boot into recovery but it cannot find the device.

 

Any ideas?

So you can't boot into recovery?

 

 

It doesn't seem like it, holding down the Power button + vol down doesn't work. Holding down power + volup until HTC screen then power + voldown doesn't work either.

 

The phone isn't recognised in Windows so I can't run anything from there either...

 

Looks like I might have to take it to my carrier :(

If you can't get into recovery that's more than soft brick imo.

Have a look at the xda-developers forum, they might have a guide or some useful tips for 'unbricking' your phone.

Every time I had a phone that didn't boot into the OS after a flash, I was always able to boot into recovery and flash something else, so I've never really been in a situation like yours before and I don't know how you would manage to do it without having access to recovery. Hopefully somebody on xda will be able to offer more help than I can provide.

It's now displaying the HTC One screen after the carrier screen.

It looks like I am running into the exact same problem you were having.

How did you manage to get the phone into the bootloader (that white screen you showed a screenshot of)?

 

Thanks!

Nevermind, I was able to get it into bootloader via:
1. Plug phone into computer.

2. Hold power + both volume.

3. As soon as charge LED turns off, release volume up.

 

Once I was in bootloader, I loaded recovery and was able to restore from backup.

If you can get into the bootloader but your computer isn't detecting your phone then it's a driver issue.

Download the UniversalAdbDriver from this website and install that. Now you should be able to get into ADB and fastboot on your phone, and from there you should be able to flash things.

Either that or get a Linux LiveCD like Ubuntu. It comes with all the drivers you need out of the box.

I have all the adb and fastboot drivers installed but still it detects only as digital camera.
