This guide works fine with L02B LCD Only

Step 1. Download the files Above and Extract to your Desktop.

After extracting the files you should see these files as shown below.

Step 2. Install WTPTP driver based on your OS architecture x86 and x64 bit.

Step 3. Install Generic MiFi Drivers manually. Now, locate device manager and add new legacy hardware and proceed to add the Marvell AT interface driver manually, this step is important.

Step 4. Test run quickly for proper installation of Drivers, power on the MiFi device and connect to PC using a good USB cable, check in device manager for
1. Not driver with a caution sign, but the correctly installed Marvell AT interface driver.
2. Marvell DIAG USB devices in USB devices..............may not be seen (not necessarily though).

Step 5. You can Disassemble and check the PCB board of the device as shown below L02B.

Step 6. Read instructions in picture

You must pay attention here: as the aim here is to disconnect the MiFi device at some % percentage when erasing the flash to allow the device to easily accept different or incompatible loaders.
Now, disconnect the MiFi at 6-10% erase flash if 3% skipped you so fast.

Connect Your MiFi device to the PC without the battery to start flashing

Step 7. when flashing the LED firmware, follow same instructions in the picture

a. Open software, Open and select SWD >> select Nehza file to load flash files

b. Tick other non-ticked files i.e all files must be ticked, select in options erase all flash

c. Now, proceed to start and connect your MiFi device without battery again to flash

d. Do not interrupt the flashing, till you get a success message.

Disconnect Your MiFi

Step 8. Flashing the Last firmware

a. The same procedure as immediate flashing done, Open and select the Nehza file to load flash files.

b. Tick other files if not already ticked

c. In the options tab Unmark Erase all flash, you must check and disable erase all flash if already enabled in Options (VERY IMPORTANT) 

Disconnect your MiFi device and insert the battery now

Insert a different Sim card you would want to use and power it on.

You will see a PH-NET_PIN each and every time you reset your MiFi device. The Unlock code is 123456, DONT FORGET IT.

Step 10. Login to the MiFi dashboard and enter the login details, login and password is "smartbro" as username and password NOT the normal admin anymore

Skip the welcome page, Click on the Internet TAB,

Select MEP settings, enter the Unlock Code as 123456 

Step 11. Unlock Code is now accepted, please wait, you should see searching for signals on the MIFI screen, it will display the 3g signal of the Sim inserted

NB: It does not support some 4g/LTE using this method for Unlock

It works very fine on all other 3g networks, few 4g networks are also supported. At least better than still being locked to one network.

12. Network and firmware should be intact as well.   Your device is now unlocked.
