HI Guys. HELP!!! My oneplus 6 just went into 'Qualcomm Crashdump mode'.
What should i do? Thanks in advance.
Usually this is because botched OS partition If you didn't flash boot or recovery, possible the OS that caused it.
There are ways to boot into bootloader directly. I forgot need to press which button combination and plug into computer. After that flash some partitions to get it back working.
