Karbonn A1+ was a good Android mobile phone in it’s range when it was launched. It was sold in a high quantity at the initial time of launching. But after some customer’s complaints and problems faced by customers at service centers, the selling of this phone is decreased suddenly. Anyways, this is not our concern. I got a Karbonn A1+ by redeeming some points I got by Airtel India as a retail partner. I purchased this phone, because there was not other good phone in the range of my currency points.

I was eagerly waiting for that phone, as it was my first Android smart phone. I thought it would be a great phone according to its specifications displayed online. But when I got this phone in my hands, I became very disappointed. I just used this phone just for making calls for about 2 months. After that, I faced many problems in this phone. One day I thought to ROOT the phone. I searched over the internet, and found some tricks. During this, I bricked phone (My touch pad stopped working). I could not root this because there is still no working trick to root this phone. I give my phone to some senior mobile repairer professional to refurbish the phone’s software, because the touch stooped working due to some file corruption.Nobody could flash this phone. I myself also tried flashing this phone, but all in vain. There is a specific tool for Karbonn A1+ for flashing. We need the package fine for appropriate H/W and S/W version. My phones H/W version is 3.0.0 and S/W version is 2.0.7. As this was a new version, I was unable to get the flash files for this version also. Although I already downloaded the latest files which are version 2.0.8. I will be giving the links for all the required files at the end. As it is a Spredtrum based CPU phone, we have to modify the standard micro USB cable. 

All we have to do is, open the CA101 cable, remove the black wire from it’s point and attach it to the only blank pin in the cable (There are total 4 wires in the cable and five pins in the socket). Refer the following diagram for modifying the cable:
