Thanks a lot for pointing me to the right thread
Yes I did use Aliexpress.
Unfortunately the seller seems not to be willing to communicate, even though he clearly shows pictures with the EEPROM in his listing.
I filed a dispute with Aliexpress and hope that I will get a refund.
The screen without EEPROM doesn't really work well with the old one's calibration data (screen swap workaround), there are quite substantial shadows after content changes...
