finally get it flashed without decompress failed error, for anyone have this laptop and getting error when trying to flash new bios, get an programmer ch341a and use linux flash tool : imsprog, import the isflash.bin to program, connect the ch341a SOIC clip to main bios chip (near dock socket), get it detects and then…

this is the video shows that it beeps https://youtu.be/z8wFGN7VXiA

same here, for me my laptop still works and last until yesterday, today it doesnt turn on anymore even thought im not touch anything to the bios firmware. the fan running at max speed for about ~5 seconds then off but nothing happens next as normal, this not hardware issues.

Beside it takes 28 seconds to POST, somehow Intel ME region also getting cleared for unknown reason and causing the issue that laptop can't be waked up from Sleep or Suspend state. This is abnormal BIOS behaviour and i trying to reflash bios for months, but "Decompress failed!!!" error still appears when trying to flash…

it just open graphical insydeflash and ask for reboot, the error still the same : Decompress failed!!!

I got isflash.bin inside the bios flash file, renamed it to B4DBUX64.fd. turned off device, connect ac power, press fn + esc then power on, the fan also run as full speed, but after 30 seconds, it have 3 beep sounds, then computer shutdown. nothing changed when i try to turn it on again

I did not find any download links for Crisis Utility SOP, even on pdf file. can i get download link for that?

i trying to flash 1.26 bios, downloaded from official acer site listed here : https://www.acer.com/us-en/support/product-support/TMP648-M/NX.VCBSV.003/downloads

no, it takes 28 seconds to post to ACER logo, which is abnormal, i also tried redownload bios many times and tried to update new bios, after windows rebooted, it take 28 seconds to post to acer logo, but decompress failed error still appears
