[SOLVED] Ulefone armor x5 pro bricked after spflashtools interrupted readback/flash - Android Q&A, Help & Troubleshooting

Hello everyone!
I have a ulefone armor x5 pro (MT6762). I tried to install twrp without success, as the port available in the forum is for the MT6763 chip variant. Before further experimenting (my phone entered in a bootlop that i resolved reflashing recovery.img), After that experience, I decided to make a backup of my own stock rom as the available on the ulefone official site seems not to be the right one (armor X5 not pro). Using SP_Flashtools, I tried to do a full reading of my device, and the power supply was cut off in the process. At this point, the device was dead. Then I was able to flash the rom provided by the manufacturer. The process was completed successfully. However, the phone did not turn on again. I disassembled it to disconnect the battery and sp flashtools recognizes it, but it remains stuck in "downloading DA 100" and does not advance any further. Try reinstalling drivers, changing laptops, different versions of the program, and SP_MDT but the same thing always happens. Downloading DA 100% (red bar at the bottom) and nothing else. At this point I don't know what else to do. My phone does not turn on at all. Any suggestion will be highly appreciated.
Thankyou!
EDIT: PROBLEM SOLVED. The problem was the firmware that i tried to download. The manufacturer has many variants of the same device name. Now the phone has back to life.

Hi, I have the Ulefone Armor X5 2020 version (android 10)with the mt6762 mediatek processor ( description of the seller, the ticket on the box and Ulefone description) this is very confuse why the stock rom for this device is for mt6765 and I read mt6765 with sp flash software.
My problem is what this was bricked from factory, its work unstable and rebooting ramdomly.
I try many things like factory reset, wipe the cache, (when wipe the cache the display show E: Fota installation aborted, E:: No such file or diretory) reflash the stock firmware, reflash preloader and recovery separately, but the problem persist.
And one of the first messages i read was system corrupted.
