LET'S UNLOCK THE BUSY LO2C VARIANCE OF M023/M028T BOOST EVEN MiFi DEVICE.

busy-m028t-unlock-jpg.355


The L02C has many board versions also. This guide will work on all the L02C16XXXXXXX, e.g. L02C160103-0924, if your board serial bears this 16XX, it implies you have the board made in 2016 with subsequent month and day which may likewise fall within the range to avoid the WTPTP ERROR message.


WHY DO I GET WTPTP ERROR?

The modem boot-loader files (fbf) which incorporate NTIM and OBMI; must be verified. The error seems to appear in some models due to the fact that these boot files are newer *(Version Date) than the firmware (files) to be flashed. For instance a board version L02C17XXXXXXX will always display error with L02C16XXXXXXX firmware, If the board date is higher than firmware version Date with month it might still display error message even with same year as in L02C1609XXXX and L02C1611XXXXX........ this is because boot file version(*Date) must be higher or equal in order to initialize the burning or erase flash.

In short, always check the board date, it must not be higher than firmware date version

NB: YOU MUST FOLLOW THE L02B GUIDE TO INSTALL LTE GENERIC DRIVERS AND WTPTP DRIVERS

LET'S GET STARTED

FILES REQUIRED


1. L02BUganda1_M023_LCD_V003_8801_2.144.000_20161117_1030_SIGN

2. GLOBE_M023J_L02C_1_30_OPENLINE_LTE

GET DOWNLOAD LINK AT THE POST BOTTOM

Some of the approaches to downgrade the device is to disconnect during the erase flash, this will damage the bootloader files in a way that subsequent flashing of the modem may now allow any firmware boot files. For this situation, you would now be able to flash any firmware of your choice to open-line modem.

Step 1. Files

Step 2. A. Load L02BUganda1 Files in SWDownloader, Tick manually RBL1 and RBLR checkbox(all the files must be checked)

B. In the Options tab, check erase all flash,
C. Click on the green bulb button to start the flash process
D. Connect the MiFi device to the PC without battery to start, I assume you have installed the driver using L02B guide for WTPTP and LTE generic drivers

E. Disconnect the MiFi at 3-6% erasing flash, if this skipped you fast, you can repeat this step and disconnect at before 10% erase flash

Step 3. LETS FLASH THE OPENLINE MODIFIED FIRMWARE

This is a GLOBE_M023J_L02C_1_30_OPENLINE_LTE firmware modified originally and LED modified With OSLO and ReliableData from L02B Uganda firmware to enable LCD and enhance MEP settings.


Flash this firmware to Openline, just like we did with the L02BUganda1 file. Allow the flashing process to finish.


Connect the MiFi device to your PC and login to IP address 127.168.1.1, the IP address changes depending on the firmware used, and Login with username as "smartbro" and password as "smartbro".

Now insert a different network sim card, insert battery now and Power On the device

You will see a welcome message allow it to load.

Connect the MiFi device to the PC, it will display PH NET PIN--

Login to MiFi dashboard

Click on the Internet Tab

Locate the MEP SETTINGS

THE UNLOCK CODE IS 123456 TO UNLOCK PN

MEP code accepted, now allow it to complete loading.

Searching for Signal 3g Network is displayed......Unlock Process Done

NB--- After Openline you need to configure the wireless Settings, some users may have difficulty connecting to the Wifi

Do manual configuration of wireless settings to function as normal

Some 4G/LTE networks are not supported due to the downgrade firmware used to Open line, Maybe in future newer firmware will improve the 4G/LTE problem

NB
After every reset of the device, MiFi displays PH-NET PIN, login and into the MiFi dashboard and click the Internet Tab, MEP settings Unlock PN with 123456 to access the network again, don't forget this
