Database [GUIDE]Karbonn A5,A7,Walton Primo IMEI writting & No Sim Problem Fixing

All right everyone here I will give u the method of writing IMEI & No Sim Detection problem of Karbonn A5/W619/Walton Primo & Karbonn A7/S01..

Many of the User of A5 are having problem with the IMEI & Mobile network lost and no sim is detecting while upgrading or downgrading Baseband.
As I have been searching for solution about a month and there is no specific solution regarding this problem..Through some ideas from different sites & developer and experimenting with my own device I have managed to write back both IMEI & enabled mobile network.
Note: For A7 user Please download AP of your device not this one.

Software & Other Requirement:

1.Stock AP of Karbonn A5/W619/Walton Primo (Original Stock GB Rom).

2.Baseband- V3025 & V3070 both.

3.Fastboot 1.0.2.4 (for downloading AP+BP to device).

4.Drivers.

5.QPST Modem Tool V1.1 (for writing IMEI).

6.QPST 2.7 (for restoring network).

[note: before updating V3070 baseband,Copy and replace 'appsboot.mbn' & 'appsboothd.mbn' this two files from the AP folder to V3070 folder in ur PC.]

3.Then update Gingerbread AP in Fastboot mode (green screen on device).
4.Turn on mobile while it is connected with the PC.PC will detect new hardware.One from them u installed before while BP Download..
5.Goto Device Manager of PC.U will find three new hardware.Install driver for them.As Shown below:




[COLOR="rgb(255, 140, 0)"]B. Write IMEI[/COLOR]

1)Unzip “Qualcomm_Modem_Tools_V1.1.rar”, open Qualcomm_Modem_Tools.exe, (Turn on ADB Debugging from Application>Development>ADB Debugging from ur mobile)
interface as blew:


(2) Select port. Port should be same as modem port.



(3) Write IMEI. Input new IMEI, click “write”.



(4) Complete writing IMEI.



(5) Then click read, confirm the new IMEI is successful written



C.Fixing NO sim problem and Network.

Now Install ''QPST 2.7.398.exe'' on PC.

(1) Open “QPST Software Download”(Start>Programs>QPST Software Download) and click Restore, interface as below:



(2) Power on handset, connect usb cable and select port by pressing browse as shown below.



(3) Now press the 2nd browse button and navigate to the folder of V3070 Baseband folder ( '591347_8376_WCDMA_V3070' this folder) and select ''591347_8376_WCDMA_V3070.qcn'' file. Now press START ,if you have done everything correctly it will go good.



(4)Restart your mobile.Now goto to Backup Tab and type a name in QCN file column according to ur choice for better understanding which qcn file is the working backup and select location where you wanna save it and press start.This qcn file is important because if u lost ur IMEI sometimes during upgrade or downgrade restoring this file will
