I've got a Nexus 5 on Lollipop that's completely stock except for running franco kernel. Haven't touched it for awhile. If I check and there are any OTA updates available, will they install successfully?
No, you must have stock kernel, stock recovery, and unroot

Thanks.
Is there a way to manually flash the OTA, or to install it one way or another, without having to revert to stock kernel and unroot and then re-root and re-install franco again?
Edit flash-all file and remove "-w".
Save the file and flash it from fastboot

As of Lollipop, the OTA method has changed and instead compares the checksum/hash of the entire /system partition, as well as the boot and recovery partitions. The "old" pre-Lollipop method was to check the specific files it cares about rather than sum of the entire partition.
The best way for you to update is download the factory image, extract it then flash the boot and system images using fastboot while your device is booted into the bootloader. You may also want to flash the new bootloader and/or radio. Don't flash the userdata image as it will wipe your /data partition (which the internal storage also resides in), unless that is something you want.
After that, boot into your custom recovery and simply flash the latest SuperSU and if you want to, a Lollipop version of the kernel you want. Files required by SuperSU/root access reside in the /system partition, which prevents an OTA update, and is overwritten when flashing a factory system image. A KitKat kernel won't boot on Lollipop, and a custom kernel also prevents OTA.
OTAs are really only for those who have absolutely no software modifications (and are not informed enough to be able to flash manually) and is honestly the worst way of updating.
hello
I just put my question here, because I have not found what I was looking for.
When I buy my tablet, I install a custom recovery, and a custom rom. Now I am back to the original rom without TWRP and root.
However, I have not found how. I thought facielement found the necessary files to do with Rodin, but I have not found. Do you know where I could find them?
If a factory restoration since the tablet will be enough? I have not tried it yet, but I do not think this is sufficient to remove the custom recovery, and root
Thank you for your help
Hi
You have to flash the stock android firmware with Odin. All firmwares are on sammobile.com or samsung-updates.com
hey, i was wondering if its possible to downgrade using TWRP?
im able to downgrade from B807 to B805 and B803 with "stock" modified backup files , so
it would be so much easier if its possible to downgrade with TWRP to B521 or B527?
is it doable, if so, how?
also, after flashing so many different roms ive noticed theres a lot of bulk files that wont get deleted,even when using "wipe", "factory reset" and the last delte option. I'm wondering if anyone knows which files are safe to delete, and/or is i possible to replace or modify .prop files?
Also, how can I tell what were the previous versions of Android that my phone had (STOCK)?
For example: there were several 5.1.1 versions or 5.0. versions - how do I know which one do I need?
Thanks.
The easiest way to have a routed rom would be to flash a stock rom from Google, flash twrp, and flash supersu from twrp.

Sorry if I didn't explain myself - my phone is rooted and I have a custom ROM. What I want to do is to go back to stock ROM but keep it rooted.
Thanks.
Flash a stock rom, then just root the stock rom. There is no other way unless you flash a stock pre-rooted rom.

So you can't keep it rooted while flashing stock?
And how do you know which versions are for your phone (if I don't want to go back to the latest Marshmallow for example)?
You can only keep root when flashing stock if you find a prerooted stock image.
Google search for nexus factory images.

Yes, I know that I need to Google for factory image, but there are several images with the same release. For example, there are three 5.1.1. (LMY48B, LMY48I and LMY48M). Same with 6.0.0. and 4 X 6.0.1 version. How do you know which one is for my device?
Thanks.
Any stock image for hammerhead will work on a hammerhead device. The reason it will delete root is you will have to flash system, and unless the system image you flash is prerooted, no more root.

Just trying to understand that difference between the different versions, or are these simply system updates, from XXX29K to XXX29S for example?
Changes in the android version 5.0->5.1->6.0 are fairly large system updates. Within 5.1.1 they are security patches.
If you have a rooted phone and talk about flashing, you should know this. Else you are a menace to your phone...
Root is a system modification - if you delete or reinstall the System partition, you'll lose root. But re-root is easy.
I recommend to read tutorials and get some knowledge before trying to root, flash or before asking those questions, where Senior xda-members just shake their heads.
The simple way to do what you seem to want is to back up all your important stuff (photos, etc.), install MMB29V (the latest March 1st 6.0.1 security version), install TWRP 3.0.0.0, and from TWRP flash SuperSU v2.70. It will take slightly longer than it's taken me to type this, but not much...
After that, when a new monthly security version comes out, flash system.img, boot.img & radio.img, and repeat the TWRP & SuperSU steps. No data loss.
How do you update oem/modem/other manufacturer specific partitions if you are on Lineage or another custom rom. Obviously OTA won't work and flashing the recent stock rom is not an option since you would (probably) lose all of your data.
Can you somehow extract those partitions from the stock rom and flash them separately?

I would leave those alone, unless you have many years of firmware hacking... Everytime I messed with them, they bricked my phone... Not worth it for what you get...
