tomytar Crash dump mode usually points to a hardware issue, most commonly related to the CPU. In rare cases, if you’re lucky, it can be triggered by corrupted firmware and flashing the official stock ROM might bring the device back to life. That said, most of the time it’s a hardware failure.
The typical fix at an authorized service center is a full motherboard replacement. Some third-party repair shops may attempt CPU reballing, which can sometimes revive the phone, but results vary and it’s not always a permanent solution.
I’d recommend trying to flash the stock ROM first since it’s low risk and easy to rule out software issues. If that doesn’t resolve it, you’re likely looking at a motherboard-level repair or, more realistically, replacing the phone altogether.
