JiaYu G3 Official Firmware Update (G3-20121129-082828)
Good news to all JiaYu G3 users out there, JiaYu had released a new and official firmware of this really awesome phone. Firmware code is: G3-20121129-082828.
Judging from it, the update started to roll out since November 29. The firmware update was release to address the problem with power consumption on standby.

JiaYu G3 ROM Firmware Update
Reports say that some of the JiaYu G3 units has a problem of even at standby, the power consumption is high. Not all phones have this problem, and so if your JiaYu G3 doesnt have this, no reason to flash this update.
Here’s the link to the new firmware files:
- via SP Flash Tool. With this, you have to extract the contents of the archive and flash it by using the SP Flash Tool.
- via CWM. With this, you just have to copy the archive on your SD card and then flash/install it by using CWM recovery mode.
TIP: Once downloaded, please rename the files from its Chinese file name to any name you desire so as not to have problems.
Just a piece of advice, your data might be lost with flashing a new ROM/firmware so its important to back-up your contacts, messages and apps if you needed to.
With this update for the JiaYu G3 rolling out, we can expect that there is a higher chance that they will continue to develop JB ROMs with their devices. Plus the fact that MT6577 kernel sources have already been released to the public. Devs can now work on bringing JellyBean to these cheap dual-core phones; MediaTek MT6577.


Thanks for this, I rooted my phone and lost the original recovery.img you don’t happen to have a link to that file so I can try and flash the oem recovery back onto the phone.
thanks for your time.
maybe you can use the recovery.img here?
Now with the source released to the public I think cyangenmod to the cheap smartphones may be possible,with the Dev help
yes that is, I just wish I could be a dev so I can work on this but I am not. Lets just hope that some devs decided to get a JYG3 and then work on a better rom for this phone.
please tell me how to flash using SP flash tool?
I installed CWM recovery on my mobile, but cannot able to access my external memmory card. I can see only internal SD, but through file manager the internal memmory shows empty.. so please help me on this
