Hi All,
I'm having this issue for last one month
When ever I select WCDMA option, I lose network. (sometimes I will get n/w for short period)
If i'm using WCDMA/GSM option, I'm able to connect to 3G.
So I hope the antenna is working fine.
I have already formated my phone using SP flash tool and installed latest rom.
I have used the format all which will corrupt the IMEI and installed IMEI back using maui tool .
I have replaced the modem.img file with latest one but the issue persist.
Since my phone is not under warranty. Could anyone please help to to correct the issue.

Solved the issue.. :) ..

the issue is because when we flash the mobile, its calibration data got corrupted.
EVEN if we reinstall the imei no. the calibration will not be there....
Those who got issue with 3G in "WCDMA" option can use the tool MAUI META to fix it..

Connect the mobile in MAUI tool -> Select the update parameter option .
click the "Change NVRAM DB FILE" and select the "BPLGUInfoCustomAppSrcP_MT6589_S00_MOLY_WR8_W1248_MD_WG_MP_V6_P18" file .
click on "from file option " and select attached file.
then click "Download to flash."
Please check this link if you got any doubt in using maui tool

Please check this fix and report me back if it worked...

    I got the stock parm from my cousin's a210 which was in Stock conditions... it cannot be extracted from stock rom firmware as its written in the nvram itself along with the IMEI no..
