Factory reset from recovery.
Sent from my SM-N920C
i did that ... same
Problem solved with JTAG repair.
Can you describe in details?
Sent from my SM-N920C
When a phone is in a hard-bricked state it’s most likely that the bootloaders, which is the phones initial code to launch the phones ROM, becomes corrupted.
The only way to revive the phone is to rewrite the bootloader code.
So basically, if you can't flash a rom through twrp or odin, this service we'll rewrite the os from scratch without having any acces to phone.

Bootloader problems ?

Hello dear community. Have been here for quite a while and now I've got a big problem with my Moto Z.
Today out of nowhere, precisely I went to get something to drink from the other room and came back, my Moto Z died.
It was at the Splashscreen stuck. So I tried to do some things already ..
So tried to boot into TWRP or flash it through fastboot > Didn't worked. Stuck on Splashscreen.
Tried to flash Stock 7.1 > Didn't worked .. Bootloader write ends with "FAILED".
Tried to format all partitions ; + Userdata too > Didn't worked .. That made it boot instantly into the Bootloader.
So now I'm here and don't know what to do.. Hope any of you can help me somehow.
I just don't want to throw my phone away with my 2 mods ^-^' ..
Ah.. and No I don't have any waranty left ..
Tried pretty much till now but it after all it just doesn't boots after the "Your devices has been unlocked screen" . No matter if custom rom or stock rom .. Anyone out there to help maybe ?

Stock Oreo ROM..
Hi dears friend.i have one question about bootloader. I'm tried close bootloader. And i get it.but with mistake.and i cant open secondary bootloader how i can open it against? Have mistake invalid boot state on pc..thanks for everyone.

my MOTO Z is a disaster !

I broke my moto z display back in 2017 and i recently got it repaired.
My device was rooted , and had nexus rom on it
So after i got it repaired i updated the twrp and tried to flash a couple of roms
After the flash every rom i have flashed is stuck in bootloop
so i went back to the service center and got back to stock os ( OREO ) !
Once its all done ! my device wont boot , instead show a NO COMMAND screen .:crying:
It only boots if i boot to bootloader and from there i select the START option
The second thing is that my device codename shows SHERIDAN in bootloader and grffin in few apps i used !
And can i root my device on oreo ! and if possible please guide me i as i could not find any reliable source !

Phone stuck in TWRP "Formatting Data" while attempting to install Lineage OS 16.0

Hi everybody.
I was following the official guide for installing Lineage OS 16 on my device (ANE-LX1) .
I arrived at the step where I had to Format Data in TWRP, but I'm stucked on the screen "Formatting Data" for almost two hours.
Is that normal that it takes so long time? What you reccomend to do?
Thank for your help.
Please guys, anybody can help me?
The phone is still stuck on "Formatting Data", almost 3 hours have passed.
What can I do? I dont know if I have to power off the phone and see what happens, but maybe this can cause serious damages.
Any help is appreciated

P20 Lite Bootloop after wipe with TWRP 3.5.0_9.0 [SOLVED]
Hi, My ANE-LX1 seems to be stuck in a bootloop. I was trying to install lineageos 16 (official) or 18 (unofficial). First I used potatonv to unlock the bootloader. This seemed to work OK, but in fastboot mode it said bootloader unlocked (red)...

Hi Alf, thank you for the help.
Now I've been able to get the fastboot mode.
What do you suggest to do from this point? (I have FRP and Phone both Unlocked). Erasing the userdata?
Edit: I've erased the userdata partition and I'm able to boot into TWRP. From this point what I have to do if i wanna continue the installation of LOS 16?
