Mr.Steve , via OnePlus 6 , Sep 7, 2021 : Hi Guys , i am also among the users experiencing Qualcomm Crash dump mode. I tried every option available on the web to revive my Oneplus 6. I have never tried to root my mobile or even unlocked the bootloader , but it just went to CRASH MODE without any reason and this is the scenario for most of the users out there !! There is a temporary method to revive your Oneplus 6 is to choose a highly experienced third party service centre , who can work on the MMC Chip of motherboard. After tweaking MMC Chip some oneplus 6 Mobiles got revived . But even those revived mobiles would still have the possibility of going again into CRASH MODE !! . But the reality is , there is no permanent fix for this Crash mode. Only few lucky users got out of this mess. Any methods mentioned by oneplus and flashing by MSM TOOL , wont help you to recover from Crash mode . Every options ended in Vain. The only solution would be changing the motherboard , which costs around nearly 14k to 18k INR , and this is the only solution offered by ONEPLUS SERVICE CENTRE . Because Oneplus service centre technicians are not trained to work on deep motherboard issues , so they will offer you only one option that would be MOTHER BOARD REPLACEMENT . So for all Qualcomm Crash mode experiencing users , if you are not ready to change the Motherboard ,then this is the end for your Oneplus 6. Every Oneplus 6 is out of warranty , so oneplus wont take responsibility for this. This is the first time i regret for choosing Oneplus. Definitely its going to be hard to choose Oneplus again !!
