Why does my Redmi 9T couldn’t restart after I tried everything to fix it?
I am facing a frustrating issue with my Redmi 9T where it simply couldn’t restart no matter what I do. I’ve tried everything from basic troubleshooting steps like holding down the power button to attempting a soft reset. The phone appears to be stuck in a loop; it tries to power on, displays the initial splash screen, and then just goes back to being unresponsive. I haven’t installed any new apps recently nor have I dropped the phone. There were no prior signs of malfunctioning, and this issue seemed to have come out of nowhere. I have also ensured that the battery is charged, but it still wouldn’t restart. This problem is making my phone entirely unusable, and I feel helpless not knowing what else can be done to resolve it.

If your Redmi 9T is stuck and couldn’t restart, try these steps:
1. Power Cycle: Press the power button for about 10-20 seconds. This might forcibly reboot the device.
2. Safe Mode: Boot into Safe Mode by holding the power button and then tapping and holding ‘Power Off’ until the Safe Mode option appears. This helps identify if the issue arises from installed apps.
3. Check Battery Connector: The internal battery connection might be loose. If you’re comfortable, carefully open the phone and check the battery connection. If not, seek professional help.

I understand your frustration with the Redmi 9T not restarting. It’s likely that the issue could stem from corrupted system files. You might want to try the following approach:
1. Connect the Phone to a Charger: Ensure it is charging.
2. Perform a Soft Reset: Hold down both the power button and the volume-down button simultaneously until the device turns off and shows the MI logo.
3. Wipe Cache Partition: If you can access Recovery Mode, navigate using the volume buttons to ‘Wipe Cache Partition’ and select it with the power button.

You could also try checking for any physical damage impairing the restarting process. Here’s a concise approach:
1. Inspect for Damage: Look for any visible signs of damage, especially around the power button.
2. Visit Authorized Service Center: If you think the phone had experienced physical trauma, take it to an authorized service center for inspection.

Experiencing this problem can be perplexing. It might help to examine if the cause could be software or hardware-related. Sometimes, a factory reset might solve the problem, although it will erase all data on your device:
1. Backup Data: If possible, back up your data using Mi Cloud or another backup application.
2. Factory Reset via Recovery Mode: Access Recovery Mode by holding the power and volume up buttons together. Select ‘Wipe Data’ / ‘Factory Reset’.

Lastly, sometimes it could be a software glitch that’s making your Redmi 9T stuck. Here’s another method:
1. Bootloader Unlocking and Custom Recovery: Unlock your device’s bootloader if it isn’t already. Flash a custom recovery like TWRP. This method can help you sideload a new ROM if the current OS is corrupted.
2. Reddit/XDA Forums: Look for advice on Reddit or XDA forums. The community sometimes provides unique and effective solutions for device-specific issues.

There is a chance that thermal issues might be causing your Redmi 9T not to restart:
1. Overheating: Ensure your phone is not overheating due to excessive use. If it feels hot to the touch, let it cool down before attempting to restart.
2. Ventilation: Make sure the phone is not kept in an enclosed or hot environment continuously.

Dealing with a non-restarting Redmi 9T can be annoying. One potential issue could be with the firmware. You could look at doing a firmware restoration, here’s what you can do:
1. Use Mi Flash Tool: Download and install the Mi Flash Tool on your PC.
2. Download Firmware: Download the official firmware for Redmi 9T.
3. Flash the Firmware: Connect your phone to the PC, open Mi Flash Tool, select the firmware, and follow the on-screen instructions to flash the firmware onto your device.
