[INFO]WARNING: Android 5.0 Bootloader and Kitkat Compatibility

Android 5.0 (Lollipop) Bootloader and KitKat Compatibility​
Everyone wants Lollipop, however it is worth considering some of the possible consequences of upgrading via OTA update.​
Bootloader:
A new Bootloader (BL) will almost certainly be included in the OTA update. It is also very likely no KitKat Kernel, stock or custom will be able to boot properly with the 5.0 BL. Perhaps the Kernel DEVs can find a workaround.
Root: (ETA: Unknown)
It may take some time to gain root access on Lolipop as on other devices this has required a custom Kernel. A custom kernel itself may require kernel sources to be released - something that has taken weeks / months in the past.
Xposed Framework:
Developer has said he will wait for CyanogenMod based on Lollipop before properly starting development of an ART version of Xposed. CM12 may take a few weeks to release. Expect to do without Xposed for at least a month, probably longer since root is also required (see above.)
Custom Recovery:
This has not been an issue before, but it is always possible a new Bootloader could break compatibility with existing Custom Recoveries. Obviously, you would not be able to restore a CWM / TWRP backup without a functional custom recovery; but even then, it is unlikely you will be able to boot your KitKat backup.
Custom ROMs:
This is another area that could be affected by a new Bootloader. It is unknown if existing custom ROMs will require new Kernels / system changes in order to work with the new BL - something that could take days, weeks or months.
Performance:
Currently the performance difference between KitKat and Lollipop is unknown. If the first release of Lollipop for Android One has performance issues, you may be unable to revert back to stock KitKat.​Possible solution:
Wait for a flashable zip [NOT OTA Update zip] of Stock Android One Lollipop ROM - this would mean your Bootloader remains at it's current version and potentially allowing you to change 'back and forth' between Stock KitKat and Stock Lollipop. However, it is currently unknown if the newer BL is a requirement for Android 5.0 Kernels.
This is taken from the Moto G thread and all credits goes to @lost101.The sole motive of this is to create awareness about the new bootloader included in 5.0

Thanks For The Info @DC07 :highfive:

Thanks For The Information Bruda !!

Nope. The bootloader was updated on my nexus 7 flo for the 4.4.2 OTA. Since this update is much bigger I think we'll have a bootloader update too.

doubts about lollipop arise

Success! Multirom running unlocked and rooted KK and Lollipop

Success!
I hadn't installed Lollipop on my 2012 Nexus 7 (Grouper) because of all the problems I read about but I decided to try it through using Multiboot and keeping KK 4.4.4 too. I now have Lollipop running, including most of the apps I have running in KK, without any apparent problems. I initially installed Lollipop as the secondary ROM. After Lollipop is installed as the secondary ROM, it takes a while for the boot process to complete the first time, it seems to take forever. In order to unlock and root Lollipop I had to make it the primary ROM and used Nexus Root Toolkit running on Windows 8.1 to unlock and root Lollipop just as I had with KK. Now I can alternate from KK to Lollipop and vice-versa.
This is for Nexus 4 but works the same for Nexus 7 if the correct Lollipop version is used:

Hi
Did yolu installed also kernel for lollipop? Or are you using KitKat kernel? I tried to install as you described but lollipop always directs me to recovery.

asking same qeustions as hugo_bjk , before i updated to LOL' from 4.4.4 i tried to multirom various 5.0 roms but none worked all went to recovery as hugo_bjk says, im now 5.0 and performance for me is better then 4.4.4 anyways and now i do have kali nethunter installed via multirom ontop of paranoid saber remix:laugh:

I also installed 5.0 kernel but no go. Still directs me to recovery.

success
Âfter swapping internal and lollipop roms lollipop boots with success.

I've been away for a few days and just read the postings since I did the OP. I installed a Lollipop kernel with the kexec-hardboot patch and made Lollipop primary. Lollipop is working well, so far.

Learning Basics of installing custom rom for newbies

Hi guys , I have been looking through xda and could not find a single discussion on basics of installing custom rom on android devices my very first question is
1.) I have a smasung galaxy note 3 n9005 currently running 5.0 lollipop version, I tries to install a marshmallow custom rom on this device but it fails and I have to again restore my back up so I want to ask whether it is compulsory to install a marshmallow kernel for a marshmallow rom or can a marshmallow rom install on lollipop kernel .

How to root ?

Hello,
I have an F8132 with the build 41.3.A.2.149 under Android 8.0.0. My bootloader can be unlocked (but is not).
I'm pretty new to xda and I've browse the forum but the latest guide to root this phone are from 2016 and not for this version.
So is there a new way to root this phone available or can you give me a link to root this version of the F8132 ?

With me having past experience with Sony devices. You can't just flash magisk using a recovery of choice and boom. Sadly, Sony thought of this. You will either need a modded version of stock or a custom kernel due stock with rooting unlocked
Existenz Oreo for example has this unlocked and extra customisation
