Dear Friend,

I Don't Thing This Is Karbonn A12 Because A12 Has Broadcom CPU, But May Be It' Karbonn A12Plus.

Dear friend,

I thought of writing a personal message to you by seeing your posts. surprisingly you are into my thread.

Yes the mobile is Karbonn A12 Plus (MT 6572). unfortunate the plus symbol is not previewed in post in title and message as well.

Bhai, please give some idea to boot back my Mobile. no new updates still I m struck there only. I have PCB pics I will post soon after finding a way.

As i read somewhere MDT multi port tool works well with dead devices.
I am trying now with SP_MDT_v3.16 Tool.
Getting below error, although i selected both bin file and scatter file properly.
Bin file not fully loaded, Please check scatter and load setting.
I removed .ini file too , but still same error.
