retry flashing using SPft -v5.1532.00 or v5.1516 @ https://www.hovatek.com/forum/thread-13970.html
lets know the outcome

are you saying you flashed ONLY recovery.img using and the device went totally dead?
and you still flashed the B3-A30 rom still using v5.1532 and the device still remained dead?
in fastboot, try this command
Code:fastboot boot recovery.img
(13-11-2017, 09:50 PM)TLKiller Exactly, I flashed only the recovery from file you sent me ([Hovatek] TWRP for Acer B3-A20.zip) using SP v5.1532 then it died completely, After that I flashed the A30 whole rom and still not working, so finally I flashed the A30 rom with v5.1728 and it worked again.
Today I tried your code in fastboot and I get kernel error (see screenshot)-note that I unlocked the bootloader

Looks like you somehow need to get the Acer B3-A20 scatter firmware

(14-11-2017, 04:49 PM)TLKiller Ok, I have seen the thread but the man who is asking haven't uploaded any firmware yet, in fact, I have read his questions and looks like his knowledges of computing are a little "deficient" I'm not so sure he will be able to do a firmware backup... (I hope he does)

Asking if he can and guiding him would be a good way to go don't you think?
(15-11-2017, 03:09 PM)TLKiller Oops, I have read my answer again and it sounds a little rude, sorry about that. Yes, you're right, he can also learn as I did, before last year I was a computing dummy but I've learned very fast, If he needs me to share any knowledge about this tablet, I will try to help him
