I changed my phone from a LineageOS (Android: 7.1.2 - LineageOS: 14.1-20180704-NIGHTLY-FP2) to regular Android and used my SD-Card on the first start-up of the new phone. The new phone (Huawei Mate 10 Lite) wrote a message about an unreadable SD card. I placed the SD card back to the old phone and got a similar message and the card needs to be formatted. (which I haven't done)
On my notebook I can find two partitions on it from the dd-image:
Disk ANDRO.bin - 63 GB / 59 GiB - CHS 7765 255 63 Current partition structure: Partition Start End Size in sectors 1 P Unknown 2048 34815 32768 [android_meta] 2 P Unknown 34816 124735454 124700639 [android_expand]
I've been trying to mount my image, but it's not working.
android_meta contains the TWRP-files for LineageOS and android_expand seems to be completely empty. I analysed it already with TestDisk and found nothing. I can't open TWRP any more on the Fairphone. When starting the phone using Lock+Volume Down I just see the "Fairphone" logo and nothing happens.
Can it be that Huawei just erased everything it could find on the card without a notification?
I found various information online on how to find the key for that decrypted
android_expand. But in my /data/misc/vold is just an empty
qohelet@laptop:~$ adb root qohelet@laptop:~$ adb shell FP2:/ # ls /data/misc/vold/ bench
I'm stuck now and don't really have much experience with these kinds of issues. What to do? Thank you
