Hello
I accidentally formatted NVRAM of my Mediatek phone using SP Flash Tool that led to my phone unable to use mobile data. Then tried restoring IMEI using SN Write Tool and was successfully restored it. The problem is, I can't use 4G. It is only on 3G mode. Tried setting preferred network settings to LTE and APN but still not able to use 4G and some other methods like factory reset, restart, etc...
I also tried the sim on other phone to check if sim is the problem but 4G works on other phone.

you need to look for another of the same device, backup nvram from it then restore the nvram backup to yours

Is this the only method to fix this? how about on maui meta? There is LTE RF Tool options in there. maybe it just need to fix 4G bands. Can't find some tutorial on internet though.
