I'm sorry to hear about the issue with your phone. Unfortunately, putting your phone in the microwave, even for a short period, can cause severe damage to the internal components. Microwaving any electronic device, including a phone, can lead to irreversible damage and potentially render the device unusable.
The fact that your phone is now stuck on the booting screen and continuously rebooting indicates that it has likely suffered significant damage from the microwave exposure.
Here are some steps you can try to troubleshoot the issue, but please keep in mind that the chances of successful recovery are low:
Remove the battery (if possible): If your phone has a removable battery, take it out immediately to prevent further damage and potential hazards.
Let it dry: If your phone got wet during the microwave incident, let it dry thoroughly before attempting to use it again. Place it in a bag of uncooked rice or silica gel packets to absorb moisture.
Charge the battery: If the battery was removed, reinsert it and try charging the phone. It's possible that the battery was simply drained and causing booting issues.
Try a hard reset: If the phone is still misbehaving, perform a hard reset. The method varies depending on the phone model, so look up the specific instructions for your device.
Seek professional repair: If none of the above steps work, it's best to take your phone to a professional repair service or contact the manufacturer for assistance. They may be able to diagnose the issue and offer repair options if any are available.
However, please understand that the chances of successfully fixing a phone after microwaving it are quite low. Microwaving can cause irreversible damage to sensitive electronic components, and in most cases, the phone will need to be replaced. In the future, please avoid exposing any electronic devices, especially phones, to extreme heat or microwave ovens to prevent such issues.
