Downgrading. - LG Optimus L90

hello, i have the d415 l90 and i need help downgrading to a Kk version.
i have NO idea what i can and cant flash in this Bootloader (lolli)
can anyone give some kind of quick run down of how to downgrade from stock lollipop to Kk so i can flash the quarx cm12 build?
Any help appreciated.

Just follow this guide: http://forum.xda-developers.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479
Be aware that you must download the v10 software, not the v20, since the latter is the lollipop rom.

[Q] Need to Upgrade from KitKat 4.4.4 rooted to Lollipop 5.0.1

Im trying to upgrade my Note 4 N910T to Lollipop 5.0.1. I've been looking around and haven't found a straight answer. Don't really care if I lose root. I just want the Upgrade. CAN SOMEONE HELP?
And I'm guessing you don't have access to Odin/PC or Mac? Then the only way is for someone to upload a Twrp backup of a lollipop stock based rom. That might work.

U need odin till someone makes a zip to update all. Baseband boot and rom. That would be a huge risk. Get to a pc and use odin.

the new official Lollipop firmware: http://forum.xda-developers.com/not...sy-steps-stock-odin-n910tuvu1anih-cf-t2903733
Here are the three tools (files) you will need to upgrade to lollipop:

No, that is just the Kernel, You need to flash the entire Firmware. Remember this is an entirely different OS.
Check out pop rocks forum in development. Has stock rom and auto root with how to.

hey guys,
I have g900a with 4.4.2 and i'm looking to update it to 4.4..4. i don't want to use odin or anything, so i'm just looking for the stock firmware.
i tried looking for it myself but couldn't find working links. thanks in advance!

thanks in advance!

Root Xperia Z1 C6902 android 5.1.1

Can anybody please tell me about any one click or any easy root method for xperia z1 C6902 android 5.1.1?
Or else just tell me how to downgrade my phone to 5.0.2
I am new to this forum so if i have said anything incorrect please forgive me.
And thanks in advance.
And also provide links if you know how to downgrade to 5.0.2
There is no way to directly root Z1 lolipop 5.1.1. You have to downgrade (to Kitkat 4.4.2 is the best), get your z1 rooted, install recovery then update it to pre-rooted lolipop 5.1.1
Use Xperia Flashtool to downgrade or upgrade firmware.
Thanks for the reply.
Can u list the steps and the links and
Also please tell me how can I downgrade to 5.0.2 lollipop.
no do not downgrade to 5.0.2 since its awful to root because you need to change from kingroot to supersu... just downgrade to 4.4.2 and install nut's recovery and it will root it for you in the process... then flash prerooted 5.1.1. and you're golden
Okay. Thanks for the reply.
Can you list the steps and the links?
You know I am just a little new.
Thanks in advance.

First downgrade to .108 and root it.
Install dual recovery by NUT
Download .368 prerooted zip
Flash that zip via recovery. Good luck
Thankyou everyone at the xda for helping me.
And for the reply also.
