Hi guys, 

Just wanted to look for NVRAM back up on the said device. I forgot to back up mine before flashing a Custom ROM, and I can't use my SIM network services as my IMEI and Baseband are currently unknown. 

Thank you,
LMA

I already flashed factory firmware, however the baseband still shows unknown, I'm currently using a GSI ROM that shows my baseband, so the only thing left is to write IMEI, which I know how to, but what troubles me now is that my phone can't be read by preloader so I cant flash with the tools

Someone with the model would have to backup for you or you use a dongle that supports IMEI repair on this model

UPDATE 

1. 
 I am now able to connect to Modem / Maui Meta
 - Directly go to META mode from BRom mode using MTK Meta Utility 
 - Set Modem/Maui Meta Port to UART (COM4 in my case) 
 - Set Platform type to More
 - Set Baud Rate to Auto 
 - Click connect and wait 

2.  I encountered an error from both IMEI repair tool saying "NVRAM Database failed to load" 
 -MODEM META:  Error shows when I go to IMEI download from Search Tools 
 - MAUI META : Error shows when I load DB 

I'm almost there, so close yet so far. I'll reply another update soon.

UPDATE:

-
I flashed GSI ROM PE 13 and able to get a valid Baseband Version 
- Tried using MAUI META, MODEM META, and SN Write Tool
- All of the methods were unsuccessful
- Errors were regarding NVRAM database not being loaded 

I already tried ADB method but no luck on IMEI to be writen.
