- In the process of applying this custom ROM Firmware update, all the data present in your phone will get erased or corrupted. So, you need to back up all the data with the help of below mentioned tips ONLY as HTC Sync won’t be supporting your device after the update since it’s a custom ROM firmware.
SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”
- Minimum charge left in the device should be at least 60% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
- Disable all the antivirus suites in your computer and uninstall the same in your device as these tools generally tend to interrupt the process of firmware update.
- Enable the USB Debugging Mode in your HTC Thunderbolt. You can enable the same from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked as shown in the below screen capture.
