There comes a time for nearly every Droid user wherein trying to install an app, you’ll find it just won’t happen if you don’t live in a supported country.
Whenever there’s an issue to be solved – at least from an Android perspective – the talented brains gracing the XDA are usually on hand with the antidote. On this occasion, it comes in the form of Senior Member Deeco7, who’s put together a modified Google Play Store .APK, rendering those annoying country restrictions as a thing of the past. Once installed, you’ll be able to download whatever you want from Google’s recently-renamed mobile app hub – providing, of course, that your device is compatible.
Installation Guide:
1.Download the apk from original thread over at XDA
2.put the apk on the phone ,don't use adb install *.apk in won't work it will say it already exists
3.Open the apk from the phone using a File explorer (e.g. ES File Explorer/Root explorer)
4.it will ask you if you want to replace the current market,press yes.5
.wait for install and voila you have the new market
NOTE: this method replaces the old market. I haven't tested this personally. May or may not work for everybody. If there is any problem report it to XDA topic thread.
Troubleshoot:
If you have download problem after Installing new market do this
" Connect your phone to your computer,
set in usb mass storage mode. Look for
a hidden folder called ".android_ secure"
and then delete the file
"smdl2tmp1 .asec". Unmount and you
should be good to go."
DISCLAIMER: Proceed with caution and at your own risk. Rimweb or Me should not be held responsible for any loss of data or any damage to your phone as a result of you following this tutorial.
