Default Optimus G E975 (Kit Kat 4.4.2 ) Sling Rom 2.1 -- Install Instructions UPDATED

Just to be sure, before doing any of these steps BACKUP your current rom, connect your phone to a pc, open your phone`s internal storage, create a new folder and name it "0", without qoutes ( that`s a zero, not a letter 0 ), put all your files to that folder.

I am not responsible if anything goes wrong. You`re doing this at your own risk.

So, to get to the point, many users have reported a soft/hard brick. I recommend you trying this method, even thought the previous method worked for me every single time. That same method is quoted in the first comment, so if you want you can still try it. Install Jelly Bean E97510h from this link ( using KDZ updater )https://mega.co.nz/#!0gtWRABR!WSbEST...Y3UKMh3m4i7i14 Make sure you have an unlocked bootloader ( download app called "freegee" from the play store and unlock your bootloader using "mako" method ) and a recovery ( I recommend using CWM ):

After that install Paulicat, just to be safe https://drive.google.com/folderview?...kk&usp=sharing
( install it the same way as any other rom - wipe data/factory reset, wipe cache, dalvik cache, format system, install zip. wipe data/factory reset)

1. download Sling Rom 2.1

https://storage.rcs-rds.ro/links/6be...b-a2c492a63cdc

2. Download patch https://www.dropbox.com/s/7a3urpzvw4...lgviet.com.zip

3. Super su http://download.chainfire.eu/420/Sup...erSU-v1.99.zip

4. Put all three files on your sd card

5. Enter recovery >> Wipe data/factory reset >> Wipe cache >> Wipe dalvik cache >> go to mounts and storage and click "format system"

6. Install Sling Rom, then Patch and finally Super Su

7. Go back, once more wipe data/factory reset >> wipe cache >> and wipe dalvik cache

Reboot your phone and enjoy kit kat.. you dont need to flash 10H modem because I`ve already included it in the patch, and you dont need to unlock your bootloader. I`ve tested this method and it works 100%, if you cant get it to work than you`re doing something wrong.


If u have installed kit kat rom and have a weak signal then go to recovery, wipe cache and dalvik cache, install 10h modem >>>>https://www.dropbox.com/s/rzpnlwu1lo...-10h_modem.zip


Thanks @sunyakram for the rom links.

All the credit for the kit kat rom goes to @hoangnova...

1.So, first thing`s first, I would recommend downloading this exact version of Jelly Bean (due to the fact that many users have reported loss of network after flashing kit kat over other jelly bean versions)
E97510H_00 (https://mega.co.nz/#!0gtWRABR!WSbEST...Y3UKMh3m4i7i14) and installing it through KDZ Updater (http://forum.xda-developers.com/show....php?t=2010624)

2. After that install freegee (https://play.google.com/store/apps/d....shell.freegee) and unlock your phone`s bootloader by tapping CWM or TWRP and choosing "mako unlock method" >> "classic" can also do the job, but in my opinion "mako" is the safer option

3. After installing and unlocking JB download kit kat rom from this link http://www.filedropper.com/vdt-v20superlitelgg, put it on your sd card aka internal storage

--- also download UPDATE-SuperSU-v1.99.zip (http://download.chainfire.eu/420/Sup...erSU-v1.99.zip) and put it on your internal storage

4. Once more go to freegee app, wait for it to download supported device list, click on the "settings" button on your phone and select "reboot recovery"

5. From the recovery make sure to wipe cache and dalvik cache.. DO NOT format anything else.. after that click on "install zip", "chose zip from sd card" > navigate to your rom file and install it.. DO NOT go anywhere.. once more click on install zip and make sure to install UPDATE-SuperSU-v1.99.zip

6. Now once again wipe cache and dalvik cache, but this time you also must do a factory reset.. click on "wipe data/factory reset". this will not delete your pictures, songs etc

7. You can click on "reboot system now". Upon reboot setup your phone, once again download freegee, install it, unlock your bootloader using the same option as before..


If you follow these steps carefully you will not have any problems. If u already have a "secure boot error" just download the KDZ file from the first post and flash it through KDZ updater. At the end of flashing phone will try to reboot, if it gets stuck at LG logo press and hold the power button until it shuts down completely.. now press and hold the volume down button + the power button.. a warning should pop up saying that you will lose all your data if you continue, press the power button to confirm.. you should be good to go.

If you have any other question feel free to ask here or send me a pm.

And lastly, if I`ve missed something do let me know

Sorry for bad english :P

have you tried turning off the phone and pressing volume up + the power button in order to enter recovery ?

I would recommend using the provided kdz file, simply because i dont know the base of those stock based roms. and mainly because stock doesnt have any removed files, unlike those two
