Hello guys, so I recently bought an E14 AMD ryzen 7 5700u locked, read a little about flashing and gave it a try, long story short I think I corrupted the this chip w74m25jwzeiq (thinking it was the actual bios). I tried to read it with the mini programmer but it shows no data at all, could anyone give me some tips on what to do now, I just bought the laptop an have no money for another one lol. It beeps heavily now when I try to boot it up without the chip, im hoping the motherboard its okey since it actually tries to boot up but theres a missing chip on the board. Before desoldering it boot up but no display was showing at all, kept restarting until I unpluged the battery. Thanks you so much I would love to get some help from people that actually know what they doing.

Solder it back on the board and see if it boots. What model is your mini programmer

Update: I ordered another chip from ebay, an original one, I was scared because I thought I desolder the wrong chip, when I tried to read it with the programmer I didnt work(CH341A 24 25 from aliexpress),I put it back on the motherboard chip but still beeps randomly and pretty loud, made a mistake not using the 1.8v adapter once, prob burned the chip so now even when soldered back to the motherboard beeps like theres no bios chip. Waiting for the arrival of the new chip to flash it with the 32mb firmware and hoping it still works.

Lesson learned, read carefully the schematics, and do a previous research on the actual chip specs
