Recently I have been running AOSP rom on the LG G2, I tried to recently apply the 4.4.2 update via the ripped LG Gpro in android developement. However to my own stupidity I did not follow instructions correctly already being on 4.4.2. The rom flashed however not correctly, with exsesive over heating and no sim connection as well as many other bugs. I have tried to re-instal custom recovery but cannot due to the 4.4.2 update. I then tried to flash a Kdz file via lg software to downgrade back to 4.2.2 but it will not flash as it connects and states that I already have the most up to date software even after adding the 4.2.2 file.
The phone is stuck on the custom rom, it is now rooted via the normal method, unable to instal a custom recovery and have had no look re-flashing a stock or another rom via software.
Overall goal is to get back to stock, and take it from there. Can anyone surgest any alternative methods to re-flash standard rom or instal a custom recovery to then apply a different rom.
Other information, phone switches on and can connect to a pc and recognised. No issues to this style of use but not able to be used a phone.
Any information would be great,
