Huawei g620s, memory card pinout


The problem is that I forgot to remove the memory card when I changed the battery, so the socket was completely ripped off!

Delivered it for repair, but they refused to repair it even if I paid

So, my idea is to solder the micro SD card directly on the main board using 0,1mm wire from a coil

Problem is, the memory card has 8 connectors, and the socket has 9.

Top of mobile, backside of mobile up

8-
9-

The pins are not uniform, the middle ones are tighter grouped.

Tried to soloder 1-8 to SC card, 9 to GND. Phone would not read the 16GM card. Card is OK, works in camera... tested it afterwards.

I have a tiny soldering iron so no problem soldering the thin wire.

I suspect some other pins are card detect?

I do not have the socket anymore it was lost...

Can anybody help? It's worth trying once more if I have the correct pinout.

Then I can use the phone as before... please help...
