General Description
When the LCD screen shows “Upgrade Firmware Failed!”, or shows “The Space is Insufficient!”.
Troubleshooting
1. Upgrade Firmware Failed!
Generally, this is because the rom used for upgrading is not right.
For example, the phone needs to upgrade to fw920M.rom, but it used fw921.rom. Or it’s because the version difference is too big, so the phone needs to upgrade to a transfer version before upgrading to the final version.
When this happens, please contact Htek technical support and provide the syslog after the upgrading has failed.
2. The Space is Insufficient!
When this notification appears, it means the space left in the phone is not enough for firmware upgrade.
The user will be reminded to reboot, because rebooting will make the phone temporarily clear up some space which is possessed during operation, thus realizing firmware upgrade.
If the phone still can’t be upgraded after multiple reboots, please try to enter Recovery Mode to clear the space and then try again.
3. System files are missing, please upgrade again!
