HELP! Phone stuck in reboot loop

[Cherirella]

4I am experiencing a repeated rebooting issue with my A51 4G device. I initially suspected the battery, so I replaced it; however, the problem persists. I have also attempted to troubleshoot by booting in safe mode, clearing the cache partition, and performing a factory reset, but the issue remains unresolved. I subsequently took the device to a repair shop, but they were unable to diagnose or resolve the problem. Can anyone help solve this problem?

It seems like your chipset on your phone (Exynos 9611) might have been corrupted by the motherboard.

The motherboard is the main component of the phones device. Its where it stores the CPU and that is essential for taking actions.
Randomly rebooting can make the motherboard fail.

Which means it's likely an issue on the motherboard.

Samsung No longer supports the galaxy a51 in updates it has been ended since April 2024 making it vulnerable to security risks and patches.

Here's a breakdown of potential solutions:

1. Forced Restart:

Press and hold the Power button and Volume Down button simultaneously for about 10 seconds.

This can sometimes resolve minor software glitches that cause the boot

2. Enter Recovery Mode:

Method:

Turn off the phone. Press and hold the Power button, Volume Up button, and Bixby/Home button simultaneously until the device vibrates and the Samsung logo appears. 

Purpose:

Recovery mode provides options for troubleshooting, such as wiping the cache partition or performing a factory reset. 

3. Wipe Cache Partition: 

Method:

In Recovery Mode, navigate to "Wipe Cache Partition" using the volume keys and select it with the Power button. Confirm the action.

Purpose:

Clearing the cache can remove corrupted temporary files that might be causing the boot loop. 

4. Factory Reset:

Method:

In Recovery Mode, navigate to "Wipe data/Factory reset" using the volume keys and select it with the Power button. Confirm the action. 

Purpose:

This will erase all data on the phone and restore it to its factory settings. Use this as a last resort, as it will erase your data.
