The aim of 7th step is to flash the LED firmware . If you having FBF errors here

Revisit the first firmware in step 6. Do not disconnect very early during erasing flash

Disconnect at about 12-15% erasing flash

And proceed to the 7th step again. It will be ok

Thank you Droidmobtech, I waited up until it was at 15% and I was able to continue. But when I get to the web interface, first the user name and password "smartbro" are failing to work so but admin works. Then on Internet menu, the MEP settings option is not there. Also the mifi screen drivers seem not to have been corrected by the last flash as its just black. What have I missed.

You probably missed the last firmware flash which is an LCD firmware that overwrites the files to get device powered on

Revisit the guide again

Don't forget to disable "erase all flash" in the last firmware flash

Untick erase all flash during L02B Cameroon file

Do exactly as I have said ; for surely you will get success

Thank you so very much. I was mixing the 7 and 8th steps. Worked just fine and greatly appreciated. Any possibility of updating to have all 4G networks?

1. Wtptp drivers may not have been properly installed: in such case run wtptp drivers click on unistall and then reinstall again

2. Its possible device is an L02B 17xxx series; in such case a newer firmware may be needed

You may post the picture of the board... clear pictures for verification

Maybe this is late but if you are experiencing the WTPTP Error: FBF_VersionNotMatch error, it's due to two things, either you've flashed the wrong firmware before or your board is incompatible with the firmware you want to flash.
The first case is my own case, I flashed the firmware of M028T on M022T, everything works just fine not until I noticed that no sim card is discovering the network, so here is how I managed to fix this;
Flash the first Uganda version, make sure you select "PRODUCTION MODE" and "ERASE ALL"
Quickly remove the MiFi after erasing it (before writing the firmware)
Try to power it on, if everything goes on well, the MiFi SHOULDN'T BOOT
Open the new and compatible firmware
flash it again but with ERASE ALL selected ONLY
Try this and thank me later
if you are still experiencing the same issue, you can send a DM on Whatsapp; +2348146800602
