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.

Is there any post how to chceck and fix the IMEI ? And what about the wrong ROM ?

Thank you

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)

OK if I arrive today at home I will check it. If any problem i will leave a feedback.

Thank you for your help !

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

Maybe admin have answer ?

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

it isnt the right way, but i cant now check all columns see the picture - preloader, recovery etc.

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
