Let me back up, you flashed the “bios to fix sdcard flickering” and this caused the brick?

If so I could only suggest you retry flashing the link I sent and keep messing around with the power buttons.

Mine appeared dead after flashing, it did not power on or flash charging led immediately.

I just kept hitting the power button while it was plugged in to micro usb to charge.

Which USB power led do you mean? I assume you tried to power on multiple times?

When I first plugged in micro usb charging wire the charging led did no flash and it did not power on immediately.

I had to try powering it on several times before it actually powered on and then the charging led started blinking.

I closed up my tablet already and I didn’t look at which version chip I have…if I have to open it up again I will look for the specific model of the chip.

<edit> I opened it up again, I do indeed have the 25Q64FWSIG chip. </edit>

However, having programmed a teclast that I know had the 1.8v chip without a level convertor I would be surprised if the 3.3v caused a burn out in your pmic. I suppose it could happen though.

Totally up to you but it worked for me is all I can say.

Please let us know if it worked for you also.

Would be nice to get a confirmation from someone else.

Big thing for programming these things is doing an erase/wipe/program/verify as a few times it looked like it programmed properly but failed verification.

To all who bricked use this file from Chuwi forums with SPI/EZProgrammer to revive your tab.

I flashed and bricked like some of you with the newer 2016 version with serial number 64G2416xxxxxx.

I flashed about 7 different bios files before this one finally brought it back to life.

I do not have a voltage step down attached to my SPI programmer and I’m fairly certain its not required.

I had messaged Chris on XDA sometime ago about similar voltage concern for a teclast I needed to flash.
