| Step | Action | Outcome | |------|--------|---------| | 1 | Boot into (Hold Volume Up + Power when device is off) | If eRecovery loads without rebooting, the problem is likely system software related. | | 2 | Boot into Fastboot (Hold Volume Down + Power) | If Fastboot mode is stable, the bootloader and core hardware are functional. | | 3 | Monitor temperature. Does the reboot happen only when hot? | If yes → thermal/power management issue. | | 4 | Remove SD card and SIM card. | Faulty external hardware interrupts can trigger WDT. | | 5 | Check for recent updates. Did the error start after an OTA? | If yes → corrupt OTA download. |
If the phone reboots even in eRecovery mode or even in Fastboot , the issue is almost certainly hardware-related (bad RAM, broken CPU solder joint, or failing storage). wdt huawei
