How to manually download and install the LG Optimus G Jelly Bean update


If you’re waiting impatiently for the LG Optimus G Jelly Bean update slated for “end of March,” we have some good news for you. One of our industrious readers, and a noted developer on XDA-Developers, has found the link to Bell’s official update lying in wait on the company’s servers.

This is the full version of the software, not the OTA file, and will require you to know your way around a few in-house LG apps. It’s in the company’s KDZ format, and is only flashable on a Windows PC, so keep that in mind before continuing.

The version has been tested on a number of devices, and will work on TELUS, Bell and Rogers. The former will also be able to access LTE out of the box, though the file includes Bell bloatware; the latter uses a different modem file, so to access LTE you’ll need to flash it by unlocking your bootloader using FreeGee and installing a custom recovery.

It may be prudent to wait until the end of the month — you do only have just over a week to go before the rollout begins — but for those impatient types, or those just wanting to get their hands dirty in some good old fashioned Android hacking, follow the link below.
