HTC U11+ problem with boot

[sardroid]

HTCU11+ with v14 - flashing fine, after flashing the charging lamp lights up, but it's still hanging on the Android logo. After factory reset charging lamp lights not up and phone still ganging on the Android logo. When I try to do logcat in fastboot shows: waiting for device. Maybe I'm gonnaflash TWRP and then I'll try?

[phhusson]

Does adb devices -l see the device?
With TWRP, you can read logs from /proc/last_kmsg so that can be useful

[sardroid]

I flashing the system.img with the command: fastboot -S 512M flash system system.img

[sardroid]

c:\fastboot>adb devices -l
List of devices attached
FA7CC1E00017 unauthorized

[sardroid]

I did not do a factory reset. Only reboot.

[sardroid]

Flashing TWRP now to make a logcat?

[phhusson]

Yeah, you can try reading /proc/last_kmsg or /sys/fs/pstore/* from twrp

[sardroid]

TWRP flashed. How to make a logcat in it?

[sardroid]

I'm sorry, but I have not done it yet.

[sardroid]

c:\fastboot>adb logcat
logcat read failure

c:\fastboot>adb shell cat /proc/last_kmsg
cat: can't open '/proc/last_kmsg': No such file or directory

[sardroid]

Do I need root?

[phhusson]

no you don't need root. anything in /sys/fs/pstore?

[sardroid]

c:\fastboot>adb shell /sys/fs/pstore
/sbin/sh: /sys/fs/pstore: Permission denied

[sardroid]

Maybe the factory reset will help?

[sardroid]

Only then that the charging diode goes out.

[phhusson]

ls /sys/fs/pstore

[sardroid]

c:\fastboot>adb shell ls /sys/fs/pstore

c:\fastboot>

and nothing happens

[sardroid]

c:\fastboot>adb shell ls /sys/fs/pstore
error: device unauthorized.
This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

[sardroid]

after factory reset:
c:\fastboot>adb devices -l
List of devices attached
FA7CC1E00017 unauthorized

[phhusson]

Right, you'll need a system.img with force authorized adb. I'll give you that in a few hours.

[sardroid]

Great news:) Thank you.

This should give you access to adb

[sardroid]

Thank you. After flashing, do the factory reset?

[phhusson]

it would be better to, yes

[sardroid]

Oki

[sardroid]

After the factory reset the phone still hangs on the Android logo and the charging diode is off.

[phhusson]

but does adb work now?

[sardroid]

c:\fastboot>adb shell ls /sys/fs/pstore
ls: /sys/fs/pstore: Permission denied

[phhusson]

yeah so you got adb working. so you can adb logcat

[sardroid]

adb logcat -d ?

[phhusson]

hum yeah should work

This one also says it is an Android 8.0.0 instead of 8.1.0

[ghost]

My charging LED is also always off while stuck on the Android logo, but my battery is full because I'm constantly plugged in while working in fastboot (LED works in fastboot/download)

[sardroid]

I never upload a system.img without a minimum of 90% of the battery.

[sardroid]

Downloading.

[ghost]

BOOTED!!

[sardroid]

Really??

[ghost]

Latest 8.0 build seems working fine after one reboot, I went trough the setup screen fine, fingerprint and camera working, all seems stable.

Do you need logs anyway?

[phhusson]

I guess that's good news, but I'm miles away from a proper fix...

Can you dump me the content of /proc/device-tree folder?

[ghost]

Regarding the other mobile data issue.

SIM card recognised fine.
It asked me to reboot when I inserted it and it asked me if I want to use SIM 1 as main sim.
It connects (I see signal bars, can call), but no mobile data.
