[MT6572 Primo F2] SIM not detected, pttycmd1 not found, NVRAM empty
I 'whole formatted' my MT6572 based Walton Primo F2 phone with SP Flash Tool.
Then I flashed the official firmware of this phone with SP Flash Tool.
Now the phone works fine but it does not detect SIM.
Also, the IMEI is shown as 'Invalid' for both SIM slots when I input *#06#.
When I try to fix IMEI from MTK Droid Tools it shows 'ERROR : pttycmd1 device NOT found!'.
Also, MTK Droid Tools shows 'Baseband v: -----'.
I am sure the problem is that when I formatted the phone it wiped the NVRAM region too.
So the phone has no baseband or radio files right now.
Although, WiFi still works perfectly.
Now the official firmware of Primo F2 does not contain any nvram.bin file.
It does contain a BPLGU file but I can't seem to modify IMEI with SN Write Station or Maui META etc.
Probably SN Write Station and Maui META etc. only modify IMEI when baseband or radio files are already present on the phone.
So I think the only way out for me is to flash a nvram.bin with SP Flash Tool.
Any ideas whether I am on the right track or not?
If I am, then how can I get nvram.bin file for my phone?
Can it be generated from BPLGU file somehow?
As you people can see that I have tried a lot of things, so please suggest/advise accordingly.
Any help would be appreciated
