[q] huawei ascend p1 lte u9202l-1 build b120

Hello
I have 2 exactly same model of Huawei Ascend P1 LTE U9202L-1 Build120. One of them is working fine all this while. However, lately, the other device stucked at the booting logo screen and unable to boot to the main screen.
I have tried ADB and Fastboot command, and it somehow managed to get the problem set to main screen, but the "Power" and "Vol Down" buttons not working when in the recovery mode and as well the main screen. However, when I tried to boot to the fastboot mode by pressing the "Power" and "Vol Down" buttons, my pc recognized it and I could enter fastboot commands, but not in the recovery mode and main screen mode....not so sure what are the exact problems and errors....to put in simple, the "Power" and "Vol Down" buttons are not spoilt, but I do not know why they are not working when in the recovery mode and main screen mode?? Whether the problem set is semi-bricked or just software corruption??
I have read the forums about using command "fastboot flash boot boot.img", "fastboot flash recovery recovery.img" and "fastboot flash system system.img", but confusing me....and I do not want to take the risk....
I would like to know is there any faster ways to clone the rom images of the good working set, and flash it on the problem set? Any experts out there kindly assist.
Many Thanks.

Failed to load/verify boot images on fastboot mode pixel 3 XL

Hi, right after 3 days I installed April 2020 security update on my pixel 3 XL, my phone's screen turns black and i can't unlock my phone. So i reboot my phone then it enter fastboot mode and it displayed "failed to load/verify boot images". I try using the Volume keys to scroll until Recovery Mode but it's still going to fastboot mode. The start, recovery mode, and rescue mode options all just go back to the fastboot menu with "failed to load/verify boot images".
I had try leave my phone on the fastboot mode screen until it die and plugging it back while holding the power button. Then it still just go back to the fastboot menu with "failed to load/verify boot images". I also try plug my phone into a different charger and USB-C cable but still the same problem appear.
Any help guys, what should i do ? Thank you very much.

What happens in bootloader when you type fastboot reboot fastboot?

Just download the android 10 factory image latest and google platform tools in that same page and unzip the image and copy those contents to platform tools and then using cmd prompt CD to platform tools and make sure fastboot can detect your device and then type flash-all and it should be back to factory condition.

Can't Access Fastboot Mode and Bootloader

Dear All.
I was trying to install TWRP and custom ROM on my devices. My Devices bootloader is already unlocked. but when i was going to enter the fastboot mode, my devices only shows this massage:
"SC Fastboot mode
long press power key to shutdown devices"

Fastboot mode

I'm trying to enter fastboot mode on my s20+ (opened bootloader and twrp installed) by pushing volume up and power button simultaneously but phone boots into normal mode. How to enter fastboot mode?

You will only have fastboot on Samsung with custom rom and stock custom rom recovery. Like if using LOS you have to use LOS Recovery for fastboot to work. TWRP does not support fastboot mode on samsung. If still on Samsung firmware there is no fastboot it uses Odin.

Question Can't Unlock Phone - Failed OTA

Hi, my daughter's G10 had afailed OTA. After reboot it does not unlock via pattern any more.
I was going to do a wipe but cannot enter recovery.
I can enter fastboot via power vol- and that brings up >fastboot at bottom on screen.
fastboot reboot fastboot brings up the other fastboot with options to Reboot system now, Reboot to bootloader, Power off but reboot bootloader fails
It is a G10 bought in South Africa
Product name ROGA_sprout
Bootloader version - unknown
Secure Boot yes
Serial number PT99652AA||6040|389
Hardware version 0
in mini >fastboot mode I can see it is in slot b and can switch to slot a but slot a does not even boot
I'm running Ubuntu but could get access to windows
I'm open to anything, TWRP/CWM bootloaders, custom roms
