Surface 4 Pro BIOS locked

Re: Surface 4 Pro BIOS locked

Dont forget dude that people are going to help in their free time

Since even with ur backup (if it wa read out correctly) the device is still dead you should open a dedicated topic for ur problem. It may help.

It looks like u damaged something maybe when unsoldering the eeprom or whatever so just a working rom might not help due to chiplevel issuses.

Open a separate topic and add informations, pictures and of course your dump file. This is a bios request only part of the forum- Pretty sure somebody will help u then

thanks for help @Vesko356
I the Pwd is removed.
In the BIOS the UUID is also removed and the ModelName is now "OEMAP Product" and serial number now "789789789". I've checked the file with the locked one in winhex and there are many hex values now empty.

i have read in this thread that only one bit has to change to remove the pwd. Can you give me the info which bit is it?

Best reguards.

Excellent, well done. I hope more people will follow your example, because at the end they will have to pay a lot more outside the forum, if this section of it will be closed.

Yes that's right. After all, one should not only take, but also be prepared to give something.

Re: Surface 4 Pro BIOS locked

Hello team, I thank you in advance. I've learnt a lot from reading through these pages. Gave me the courage to open my locked SP4 (only broke the display cable d'oh). I've removed the BIOS chip, read the data. I see on line 00606620 the following data.
00 FF 07 00 F9 07 00 00 00 FF FF FF AA 55 3F 00
From an earlier 'clue' is it the AA entry to change? If so, to what please?
In case I'm way off base, I've also attached the BIOS in question, for your review.
Again thank you for, if nothing else, giving my the gumption to even try this mission.
