Hello guys and gals!

I noticed that Android Forums didn't have much support for the L90. This is for D415 variant on T-Mobile.

Prerequisites:
1. Be Rooted (I will make a guide for this as well)
2. General knowledge on ROM installing

Downloads:
Download all of these files on you device's sd card, or download them on your PC and then transfer them to you sd card.
1. Download ONE of the recoveries listed here DOWNLOAD
Thanks to Shoxy and Shinobisoft for these.

-PUT THESE ALL ONTO YOUR EXTERNAL SD CARD!!!-

2. Download ONE of the following ROM's and their gapps/patch files:

[PAC ROM] ROM - GAPPS - Thanks to Demonslayer12349 and Myself
[CM11] ROM - GAPPS - Thanks to Shinobisoft and Quarx
[CM12.1] ROM - GAPPS - Thanks to Quarx

Install:
Install "Flashify" from the play store.

Step 1:
Open Flashify and select "install recovery".
Choose select file.
Browse to your external sd card and select the recovery that you downloaded earlier.

Step 2:
Use flashify to reboot to recovery.

Step 3:
Select 'Backup' and run a full backup to your external sd card!!!

Step 4:
Once the backup is done, go back to the main menu and select 'wipe' and do a factory reset.

Step 5:
Select install and browse to the ROM that you downloaded earlier.
Install the ROM and GAPPS file.

Step 6:
Reboot and you're done!

Sorry, I am stuck at rooting the device (L-90/D415), it looks like LG & T-Mobile has made this rather difficult. Hence, any help in this regard will be much appreciated. Note, the following does not work: towelroot, getting to recover mode, reboot recovery, or any key combination. I am told that the CM installer does not care if its rooted or not. Can you use the CM Installer to install this ROM or at least root the device?

not working.

are the files meant to be unzipped?

No leave them zipped. Take those .zip files and put them on your Micro SD card. Then in your recovery you flash the .zip file using the "install" function on whatever recovery you are using

how necessary is the patch for cm12? i didn't us it and my phone is lagging. not sure if that is the cause. anyway i have gotten it to work. the only problem is that it's slow and the setup keeps saying "your tablet" when i have a phone.

It is 100% necessary, if you don't the phone will not work properly and will keep crashing upon locking.

Did you clear your cache an dalvik cache before installing? That could be the slow problem.

As for it saying "your tablet" it is completely fine, nothing bad will happen from it :)
