I have problems with my BV6000. I had stock ROM from factory - i dont know how version it was, but I got a viruses into phone and flash to this ROM 20170708, but the phone losts the signal.

Then i flash via SPflashtool this ROM 20170719. So the phone didnt detect any SIM cards.
Then I flash via SPflashtool this ROM 20170321 and the signal goes down too as in first case.

Then i downloaded oldest ROM version 20160822. But I cant load Scatter -loading file into SPflashtool.

Can you help me with this problem, what i doing wrong ? Can you I fix my problem.

Can you check it ? I attached a photo of this problem.

Thank you

Maybe you just lost the IMEI ? Check it and rewrite it if IMEI are lost.

Check IMEI in your phone/settings/about/status/informations IMEI
If needed (IMEI lost), use this tutorial :

For the SP Flash tool error, try to use an older version of SP Flash tool compatible with the old ROM (if you really need to change it)

So what SPFlashtool is compatible with ROM 20160822 ?

I tried this versions of SPFlashtools :

SP_Flash_Tool_v5.1504_Win
SP_Flash_Tool_v5.1552_Win
SP_Flash_Tool_v5.1628_Win
SP_Flash_Tool_v5.1716_Win
SP_Flash_Tool_v5.1728_Win

and i cant open Scatter -loading file on ROM 20160822. I think the ROM is corrupted.

Thank you

It's very easy.
You have to rename "Checksum.ini" to e.g. "Checksum.ini1".
Happy flashing.

If I delete from ROM version 20160822 folder :

Checksum.ini and CheckSum_Gen.exe everything was OK and I could flash the phone with this ROM.

TY for help
