Must verify the settings of your programmer and of course the contacts in the socket of the flash, it always needs to detect device ID . If you to succeded to read device ID, you should to read - write 29f200 perfectly.

After cleaning many times, can detect device ID, but when try to write stopped at 6%

Bad contacts in the socket, this is for sure.
That`s why i prefer to use soldering type adapter. A little time-consuming soldering - desoldering on the adapter but never bad contacts and avoided problems like yours .

Just to add to knowledge about Flashrom.

Had the same problem with GQ-4X ... when I tried to write 29F200BB ... and they were bad contacts, and I could read it just fine... and the device was not identified as you mentioned.
