[Completed] Karbonn A12+ no power or light up but device detected in windows - XDA Assist
Hello XDA assist,
Mobile - Karbonn A12+ (MT6572)
Issue - mobile not powering up or lighting display at all even while connected to charger no battery charging indication. Only hope I see is when I connected without battery to computer device drivers detected which is usual for hard flashing.
Notes - Mobile had not fallen and in working condition on my desk , last time I see it on 16% battery suddenly it became off & never light up later.
Current installed ROM is complete fresh and very few apps. Earlier to day I m trying to fix or disable proximity sensor detection with few rooted apps like xposed modules etc but none worked. Later thus also I did lot of internet browsing as well before BLANK OFF.
Trials & Findings.
Long press power button for 1 min.
Shorting +- terminals of power button.
Power + volume up for boot mode.
Connected with out battery to computer for adb boot even Without power+volup its being detected after every 3 secs in windows devices as below but not lighted its display any time....
In Device Manager, it detected as follows...
>Mobistel Cynus F4 PreLoader USB VCOM Port
=== New Trials & Updates ====
I could find that it must be a HardBrick, as not lighting up but still detected in windows.
I did scatter_loading using Sp flash tool & i got download OK message.
But still i am unable to boot it or light up my screen nor battery charging.
Ran a memory test using Sp_Flash tool, below is the result.

Sim Detected/No Signal "can't connect to this network at the moment try again later" Hi I had my phone flashed with a custom rom. But later i wanted to switch back to stock. I used the SP tool to flash Back "sprout_reference_pack_1379542-KPW53_ALPS.KK2.AOSP.SPROUT.SP.p52_karbonn". But before flashing i accidently used the "Format" tab of SP tool. After that i flashed my phone to stock. I have no signal. Sim card is detected. I tried to switch to lollipop stock still the same error. I switched to other roms too but still no Signal and "can't connect to this network at the moment try again later" if i do a manual connect. I noticed that first 2 or 3 times on each rom the manual scan select gave error "Network search error".

You need a usb to uart device to get started on that board. You can find one online for about 3 dollars.
