Hello,

I'm getting an error trying to roll back to the default BIOS 1.0. I have the 4GB 64bit Z8300 LattePanda

Reading flash . . . . . . . . . . . . . . . done
- ME Data Size checking  .  ok
Secure Flash enabled, recalculate ROM size with signature . . . Enable.

I found the solution.

Edit the startup.nsh file and add /l at the end of of the commands

I have same problem. Already edited startup.nsh with add "/l" but no working. I need to roll back to default BIOS. :( Need some help..

@abbiebinbin Did you flash any other bios version on this board？Did you confirm the version of lattepanda board？ And may be you can post this problem on lattepanda forum， our techsupport guy will help you figure out the reason.

I wrong flash v1.1 bios to my cr110 z8300 LP. But i check my bios detail it list cr100 model. I still can boot to window. Only the problem is after clean install the bluetooth and wifi not working. I try install driver but keep said error code 10. I cant reflash back to default bios.

Bluetooth and wifi is a driver issue due to Win 10 creators update. Rolling back drivers to an older version fixes it or installing the manufacturer driver instead of the drivers windows finds automatically.

Hi, is after clean install window 10. Haven't update to win 10 creators. Normally after re-install the bluetooth is auto active right? I remember first time re-install it have bluetooth. After I flash my bios then the bluetooth no working anymore.

@abbiebinbin check the Device Manager -> System devices -> Realtek Bluetooth UART Bus Driver， is this driver installed correctly？ We leave the WiFi and Bluetooth driver v1.0 on the LattePanda win10 software driver repository

Don't have this driver installed in my LP, I got download driver zip files from github. But it show broadcom not realtek. Is it in BT folder for bluetooth driver? Mine is 4/64gb ver.

broadcom serial bus driver over uart bus enumerator is this one? but code 10.
