Root Stuck on the LOGO screen

[Hussain_awad]

Hey there, I have had a strange issue, I have been using the m8 rooted for over a year and whenever I want to download updates, I change back to stock recovery download the update then go back to custom recovery.
However, this time I downloaded stock recovery, downloading the update , and when it finished installing It got stuck on the logo screen! I have read about this situation, but I have s-on and stock recovery!
Is it possible to install a stock rom using the stuck recovery? If possible I would really appreciate a help .. I'm a student and my phone has everything on it .. thanks

Not in the sense you want to get this installed. Have you tried press and hold vol up + power to force a restart and see if it boots?

Yeah i have, it doesnt work, shows a black screen, and doesnt do anything , so i assumed the update process didnt go well which broke the system's files , any other ideas?

Yep. Since you switched between custom and stock recovery, do you have a TWRP backup you can just restore?

Can you access the bootloader and is it still unlocked? If so can you post so I can check:

model number
what OS version number shows up

Also, what carrier you are on?

Unfortunatly i dont have a back up, but the weird thing is when i connect it to laptop it says fastboot usb and laptop does the sound of connected device but fastboot doesnt recognize it

 

[saltire]

In fastboot mode, if you do

fastboot devices

What happens?

 

[Hussain_awad]

Nothing it goes to next command

 

[saltire]

What do you mean it goes to next command?

Are you in command prompt in folder where you have adb and fastboot exes.

Sounds like a driver issue though, do you have HTC Sync manager installed on laptop and did phone connect ok before?

 

[Hussain_awad]

hold on the fastboot worked, what do i do know

Ok, at least we can get you a working phone again. But when you say everything is on your phone, what does that cover?

Process to get you a working phone again is going to wipe system, data and cache partitions, and although it should leave your internal storage intact we don't know if the OTA update has borked something. Internal storage is where your might have photos, docs etc saved.

Other stuff eg contacts will get wiped but if they are Google contacts will be synced to your account so should be ok.

You need to be prepared if there is stuff lost, but if you've exhausted trying the possible ways to boot the phone with no luck it may be the only way.

Okay i will be waiting , thanks for your patience with me

Ok, process is exactly the same as my post in this thread here:

HTC One M8 unusable!

but with one important difference, as you have different firmware - you have 4.16.401.13 - you need a different TWRP stock backup, and stock recovery in step 1).

The stock TWRP backup can be found in this post:

http://forum.xda-developers.com/sho...8df272fddca77a57b9dd9b&p=60211235&postcount=2

scroll down to the long list that starts with CID HTC__001 and click on the show content button, and click the 4.16.401.13 download link.

Stock recovery [if you want to do these steps] can be found here:

http://forum.xda-developers.com/sho...8df272fddca77a57b9dd9b&p=60211779&postcount=4

scroll down to the 4.xx.xxx.xx section, click on the show content button, and scroll down and click on the 4.16.401.13 download link.

Note in the prep steps, as a further check make sure that when running the "fastboot getvar all" command, Version-main also lists your firmware version as 4.16.401.13.

Lesson learned here, especially since you seem to be comfortable in flashing a custom recovery, seems pointless if you don't use it to do a full nandroid backup to your external SD card regularly. If phone gets back to a working state I'd recommend you do one straightaway as well.
