Huawei U3900 Data Recovery

Postby DataMedics » 12.04.18, 19:16

So I've got a customer here who insists on getting pictures recovered from a cheap-o flip phone Huawei 3900. From the specs it looks like the phone has only 128Mb of memory but it is capable of storing pictures on the internal memory based on some comments on their support thread (discussions regarding how to transfer pictures from internal memory to the microSD card).

The phone is completely trashed with lots of missing components it appears. I do see that it has a chip labeled TY9A0A111283 which I assume is a BGA NAND or eMMC of some sort (I haven't removed it yet to see what the pin config is).

Anyone know if this is something that's possible to accomplish using PC-3000 Flash? I don't normally do phone recoveries, especially from - old flip phones.

As an update to this, I managed to finally dig this chip out of all the glue (it was literally glued underneath the chip) and get it removed. Looks like it's a BGA-107 ??? Any idea what this is? Is it a NAND or an eMMC? I can't find any specs or datasheet nor have I ever seen a BGA107. I guess that pinout does exist though since there are adapters for it: https://www.elnec.com/en/products/progr ... 51_ZIF-CS/
