serial provided doesn't fit with serial from bios backup which seems to be from a CX22NA and not C523NA

[mferna14]

Dear this is only serial, I re-checked several times which is on at the back sticker of the laptop & from the ASUS Web site, comes up with the same model. Attached is the photo. Can you modify the serial # or trim it to the size if possible & just to inform you I purchased this motherboard from eBay as the original motherboard got dead & now this new one is locked. You know how they sell. This motherboard has been changed, I would not bother about the serial # or model # as long as he modified BIOS is working & Not locked to any Gmail Acc & maily it's out of ASUS warranty. Thanks dear for the help.

patched w RC unlocker
then filled !stable_device_secret area with FF

Thanks Brother., I wrote these bin files to the Chip, all worked but still it is asking for "Device Enrollment". It gives ********@rosebudacademy.com ... Can you pls. look into this, maybe you might have missed something. I did a complete factory restore again but still no luck.

Good Day Dear.,, the problem was with the 64GB NAND Flash Memory eMMC chip. Actually all data was stored on this chip & even after a complete factory restore, this data was never deleted except if I knew the password & then could have done the Power Wash. I replaced with a good chip & restored back to factory default, all works 100% with completely new user. Thanks buddy for all the help, really appreciate.

Hi Friends., Can someone re-build this BIN File as it gives error while restoring back to factory default. I think the CleanME region seems to be corrupted... Thanks in Advance
