[Question] MTK 6582 Baseband empty nvram question

[simoneguarrera]

Hello again

Well after a LOT more experimenting with various roms, I found something I hope someone knows how to handle.

I have flashed quite some roms, most did not pass boot screen, but of all those that did...the same problem occurred, NVRAM section is always incomplete (missing md5 folder with the additional info for Imei and such) So SIMS don't get detected.

Flashing back to stock rom doesn't seem to have the same problem (Imei/sim detection working fine), so my question is there somewhere in the stockrom I can look to find some clues as to why NVRAM is always incomplete with any other Rom (maybe signature verification?)

Roms passed bootloader on KingZone N3:
Color OS KK by Tanveer (only worked with stock boot.img)
MIUI V6 for spice 509 (had to do a boot.img port as well)
Pure Stock 4.4.4 Rom For Maximus IX (only worked with stock boot.img)

Roms seem to run fine except for the part that Baseband null/Imei problem

If anyone has some clues where to look, would be much appriciated.

try to remove with root explorer the folder /data/NVRAM and wait some minutes, in some cases the kernel ricreate the folder with all information of the baseband of the phone.... if the problem remain try flashing the baseband using MTK Bird flasher
