Restore stock recovery - G4 Q&A, Help & Troubleshooting

Hi there, wifi not working and called LG who will take it back for test/repair as it is under warranty. Need to remove TWRP and install stock recovery. Can someone point me in the right direction on how to do this and where I get the image from?

I'm looking for stock recovery also, H811, tmobile variant. You know where I could find it, been looking for days with no luck. I found a stock complete rom, but no recovery...

If you can't find it on xda I wouldn't know where else you would. Sorry I can't be of any more help.

if its an E975 running JB it sounds like its already rooted seeing as no official 4.1.2 has been released yet for that model unless that's the korean model . I could be wrong though. Wouldn't be the first time. Check in app drawer for super user icon.

You can root it with the method posted here: http://forum.xda-developers.com/showthread.php?t=2112190
Might take a few tries but it works as I tried it on the E975 KDZ a couple of times.
Then download busybox from market.

Thanks... it works beautifully!
Now I think to think of how to fastboot recovery into this phone. Can't seem to be able to enter it..
This LG phone sure is a learning curve for a former Samsung s3 user

Maybe jump on the IRC channel and ask for the E975 freegee if available. It will unlock bootloader and inject cwm for you. Then you just reflash a newer cwm version which can be found in the AT&T section.

Hi,
i have red different things about how to root an e975.
So i have a few questions before to root my phone.
Is there a better method than another to root my optimus G?
Is there a way to unroot it easily later?
If i unroot it, will it be exactly the same as a never-rooted optimus g?
Will it be possible to update officially my phone when an update will be available? (with root? unrooted?)
thanks for your answers
the easiest way is to use motochopper to unroot, after u need to unlock the boot loader with freegee available on the mp...
now you re ready to flash a new ROM.
at your own risk....
ask yourself what u want to achieve with root... if you want to get the last stock lg experience, you don't need to root.

Using the Canadian d852 LG G3, I'm getting a "(780) fastboot mode" error on boot. Luckily, I had a backup, but can't figure out how to get this to work. I am using Cloudy G3 1.2 rom and flashed the d852 variant.

I am not sure but you can try "stump root" in a few minutes without knowledge or risks.

Here you go
http://www.mediafire.com/download/x6532xvt6x44m26/D852-KK-stock-oversharpening-off.zip
first take a backup of your boot partition, just to be safe. Then you can restore only that if something goes wrong.
And take care to flash this file ( the other has the same name)

If you just want to root your phone, try towelroot.apk. You must be really lazy because a Google search on rooting lg-e980 will tell you about towel root app.

I've done it. I reverted from IronRom lollipop to Ironrom KitKat with no issues. No need for odin as the lollipop bootloader can run KitKat fine.
Just find a custom roms for KitKat and flash it through twrp

Thanks i did and i am running 5.o.1 lollipop stock. Everything is running smooth EXCEPT signal which very low, lower than before. The switching between 2 and 3g is terrible. Do i need to flash a baseband? If so where can i get for f240l?

Good Amigo, Im sure you can find what you are looking for somewhere on the LG forums, just type it in. I could not truthfully answer your question.
L signal was very weak. So i flash to f240k20d and the signal is very good. I received an ota update of 16.xmb. Which took me to f240k30e. Everything is working smothly
