If you're coming from a KitKat ROM, you need to install a minimal stock LolliPop upgrade before flashing CyanogenMod.

aha i had stock Rom , i deleted everything .. where can i find minimal stock lollipop ?

First any download Custum ROMs u want along With Gapps, and flash the ROM zip and Gapps zip with TWRP recovery,
I prefer CM for stable ROM, and if u want lots of features i prefer AICP and if u want AOSP based rom i prefer Tesla, and Gapps i Prefer "TK Gapps Modular Micro", (search tk gapps in Google)

Is there is any simple method to update to lollipop for ROOTED Moto-E users...
Go to TWRP and wipe "cache". Reboot to system.
Hi bro thanks for replying but one thing since i have rooted moto E n already installed TWRP, WHEN to wipe CACHE its before installing soak test1 having 341mb file or when it automatically gets into recovery mode while installing above update???

If you wanna update, flash stock recovery, only then it will work. Also, you need to have an unmodified system so you probably have to flash the entire stock ROM 4.4.4 only then you can update. Or if you wanna get out of the bootloop, just wipe cache.
Follow this: http://forum.xda-developers.com/moto-e/development/downgrade-5-0-x-to-4-4-4-stock-firmware-t3031073 and then update.

[Q] Downgrade Galaxy Alpha SM850F

Hello !
I try LOLLIPOP for 2 days and i want to come back to KITKAT because some Xposed modules i need don't works on 5.0.2 (wanamlite for example).
I try to put RESTORE my KITKAT rom but when it boot up , i have nothing into my files... (partition move ?)
So i try to flash a rom with ODIN into 4.4.4 and it fail -_- (2 or 3 roms i try!!)
did someone have any solution ? i see this vidz : https://www.youtube.com/watch?v=PFELFws-CTg but it's a 5.0.2 ROM into it -_-
thanks....
You can try to install TWRP recovery and wipe /system, /cache and dalvik cache before flashing KitKat with Odin. First flash STOCK SAMSUNG KITKAT ROM because you need the bootloader included in there...
Or you stay on Lollipop and try wanam xposed for Lollipop

ok. no problem for that !
small tutorial. Look what you have to do!
download your stock firmware from here: http://forum.xda-developers.com/lenovo-p780/development/p780-stock-rom-links-t2842399
Use only this 2 tools to flash: https://drive.google.com/folderview?id=0B_B98oK4DpK1S1l2bXRkTGxhVFk&usp=sharing
If you use other tools you can corrupt your NVRAM and loose IMEI.
After flash you need to install TWRP. Here is the small tutorial and tools: http://forum.xda-developers.com/lenovo-p780/help/rooting-tutorial-kitkat-t2835605
After TWRP install, you can install any zip file firmware. Here is what i reccommend: https://drive.google.com/folderview?id=0Bw-fSKX78W43R0xHSXVMajNucFE&usp=sharing
MIUI 6.1.21 is the file you should install. ROW version.
Good Luck.
Waiting for feedback!

Its an OTA update and i have made a dload folder in my sd card and copied to update.zip file. but it fails everytime. what could be the problem?

In case somebody in this thread is interested in a solution, I managed to install LineageOS on a Honor 5X KIW-AL10 with the latest stock firmware KIW-AL10C92B437.
Once you have unlocked the bootloader, flash TWRP with adb, you need to flash Lineage OS & a zip that will fix the loop (see: https://jira.lineageos.org/browse/BUGBASH-222?attachmentViewMode=list). I used Fix_boot(422+).zip. VoilĂ !
