I changed my GPT (in the wrong way) and seem to have put one SOM in this mess:
Android Bootloader - UART_DM Initialized!!!  welcome to lk  platform_init()  target_init()  SDHC Running in HS200 mode  Done initialization of the card  MBR signature does not match.  MMC Boot: MBR read failed!  Error reading the partition table info  panic (caller 0x8f61b644): ASSERT FAILED at (target/msm8916/init.c:203): 0  SCM call: 0x2000110 failed with :ffffffff  HALT: reboot into dload mode...  SCM call: 0x82000901 failed with :ffffffff
MBR fail, is concerning… Is there a way to recover from SD? Rescue doesn’t seem to work on this SOM - on another one yes. Am I stuck?
