After Green lines issues, OnePlus devices especially 10 Pro, 9 Pro and 9RT users have reported a critical issue with the motherboard, causing it to crash suddenly and then RIP. It started happening after August or July updates were pushed to their smartphones
OnePlus service centre is demanding Rs. 42,000 (~500$) for OnePlus 10 Pro 5G Rs. 27,000 (~350$) incase of 9 Pro to repair their motherboards. Many users shared that after downloading a software update, the phone kept beeping and froze. For some users, the device would lag and then heat up before shutting down completely while for others it stopped responding randomly and just crashed.
A user's 9 pro started displaying "battery error" message and after few days, it started showing some random texts, sometimes a CRASHDUMP mode or other, a random page full of technical stuff. OnePlus, however, said that they failed to fix the issue with software replacement & battery replacement and then in the exact same words claimed — "NOTHING CAN BE DONE TO YOUR DEVICE. THE MOTHERBOARD IS DEAD. YOU SHOULD GET A NEW ONEPLUS DEVICE."
