Hi,
some time ago I'm flashed my BV6000, unfortunately with option "Format All + Download"...
First problem after this was lack of IMEIs, I restore them by SN_Write_Tool, and phone was start working, but not exactly like before.

Now phone have problem with 2G/3G connection - only sometimes phone is connected to 2G/3G (outside building, near BTS, etc), but connection is very unstable. What is strange for me - 4G connection is ok, is very stable.

I'm disassembled my BV6000 and reconnect all cable linking, nothing changed.

I suppose that "Format All + Download" erased whole NVRAM where was more that just IMEIs. And unfortunately I don't create NVRAM backup before...

I try this: viewtopic.php?f=142&t=128401&p=308642#p308642 but nothing helped.

Do you have idea how to fix this problem?

@blackview_admin:
it is possible to get NVRAM image from you?

or somebody else can help me and send own NVRAM backup? (of course, I change IMEIs and WiFi/BT Mac's address to my own)?
