Here you have the latest official lollipop firmware for D855 ( v. 20A - LRX21M) packed in a zip flashable file.
I made this because all of us want to keep the old bootloader that is - at the moment - the only one who accept the bumped TWRP provided us by team Codefire.
I made also a step further and found a way to root this ROM.
Here you go:
First of all i suggest you to install the TWRP modded by me to allow the backup of the modem.
Be sure you select also the modem partition before taking the backup. ( If you want to restore the backup then restore also the modem )
1- download the two files and put them into the sdcard;
2- reboot in recovery and do a factory reset;
3- install the ROM and the supersu ZIP;
4- reboot the device and enjoy your rooted Lollipop ROM.
If you come from an earlier lollipop firmware you can dirty flash, it might work.
I spend a lot of time developing this so if you think i deserve you can donate ( look at my sign )
SUPERSU flashable ZIP
KK MODEM ( you need this only if you downgrade from lollipop to kitkat and you don't need if you backed up before with the modded TWRP recovery)
DONATORS:( really tnx guys)
