[Q] Galaxy S II NAND issues
After recently updating my S II to CM 10.2, some battery issues occurred. When i reflashed my phone to CM 10.1, the phone had boot issues.
My situations can be summarized with the following symptoms:
- The phone does not boot normally, and doesn't even turn on at all while it's not charging
- When the phone is charging, the charging screen appears in a loop. It doesn't give an actual battery reading, but reboots instead.
- Download mode is accessible and I'm still able to flash using Odin.
- Recovery mode is not accessible.
According to numerous other threads, these symptoms indicate a NAND r/w corruption. My bootloader could be damaged too.
I have already followed many guides to fix this issue. None of them had these symptom combinations as my phone. These threads didn't solve my problems. I also tried Samsung kies to reset it to factory, but it returned an error message in Korean instead.
What kind of brick is this? And how can I make my phone boot normally again?
I really appreciate your help.
