Dear Peste

Many thanks for your quick reply. Bought the board on eBay. The only supporting information I can provide is as follows:

- 820-00165-A (printed on the board)
- C07705300NCGTQMDX (Board SN from sticker on board)
- MLB 1.6G HY 8G ON (from sticker on board)
- Firmware lock applied
- Board does not boot anymore

Any other information not available. Sorry. It is not much, but eventually enough for a first judgement.

Many thanks for your kind support.

[HR][/HR]Dear All

First time to flash a prom in order to remove a firmware lock. Unfortunately ruined my bios with the clip of my programmer (ch341a). In the meantime I have learned that my programmer is not providing 3,3V which is needed for my chip "MX25L6473E". Have ordered a new one (Rev. 1.7) which will be delivered in about 2 weeks.
The only dump I got is the attached bin file. Any chance to rescue this?
Macbook Air 820-00165-A board from 2015.
Many thanks for your help!!!!!
