ACER ChromeBook C733-C5AS

[mferna14]

Hi., I purchase two ACER ChromeBook C733-C5AS from eBay. Upon turning on I see both are affiliated with school's name, & it's asking for the gmail email & the password, Ofcourse this info I do not have. I have attached the original Locked BIOS Bin file. Is this info written in the BIN files or on the SSD chip??? I use the Bin file from post #12 but did not work. Then I downloaded a fresh BIN file from another site & it worked fine & did do a full factory restore. But the lock condition is the same, No change, asking for email & password. I can try again if the Original BIOS is unlocked. I am assuming this info is written on the SSD chip which cannot be erased, similar to iCloud. Can some put some light on this kind of error. Thanks in advance.

Re: ACER ChromeBook C733-C5AS

Good morning @aldopc., I programmed the Bin file in #2 you send me. I soldered back the chip but no Display. I think a little more changes, then might be ok. Can you please look into it again. Thanks in adavance.

WORKED 100%.. But still geting the same "Enterprise Enrolment" message. I think this is written either in the EC or the SSD Chip. When connect to the net, this message appears right away. Do you have any idea about this message as of where is it generating from??? Restored it twice.... Thanks for all the help.

@volinakis., The BIN files which you sent me is not working at all. No Display. Maybe some cleanup required. But the post # 6 working 100% fine but still give the Enterprise Enrollment error. Do you know whether this info is stored on the SSD IC or the EC chip??

Re: ACER ChromeBook C733-C5AS

@volinakis I checked the 8 pins carefully & infact this is the 5th time I am soldering the chip. The contact are 100% good, trust me & I even used a iron to solder on the pins. Since this did not work I used the BIN on post #6. Boom all worked fine, but the error still exists. Do you think this BOM info is on the 32GB SSD? what you think? other than this error Laptop is working fine.

Re: ACER ChromeBook C733-C5AS

Hi @volinakis, the Bin file which send me is working too, accidentally without knowing I programmed the bin file on a 3.3v BIOS chip whereas this had to be programmed on a 1.8V chip. All works fine but the "Enterprise Enrolment" error message is still there. Might have to replace the SSD chip. Thank you guys for all your help.
