Warning! Don't flash Measy U2A Stock on Conrad U2A Clone

[etna0815]

I've bought a U2A device from Conrad (germany) and tryed to flash it with Measy 4.22 firmware update. This U2A doesn't boot.

After this i have flashed some UG802 firmwares. Firmwares for UG802v1 boot but has no Wifi and the UG802 clone (v2) doesn't boot.

The PCB is green and looks like UG802 V2 clone with Reset Button and "MiniTV SW601" sign but the AT88SC... is missing.

Got Wifi back

After some Research and PCB tracing i have found the important difference between
UG802v1 and v2 that blocks the wifi with v1 kernels.

There is a MOSFET (blue circle) that control the 3.3V power of the wifi module. This will not enabled by the UG802 v1 kernels. After adding a solder blob (red circle) to bridge the MOSFET the wifi is always powered and UG802, Minix G4, MK802III Roms and also 2dark4/Finnless 1.7 will work with wifi.




I can only flash with RK30xx Loader v1.11 or 1.28 (1.14, 1.16, 1.20 and 1.22) will fail after loader Upload. But the roms are working. (some with 1.11 and some with 1.28)
