Root Update N5 to 6.0 with root?

Rousku · Oct 8, 2015

Hey guys!

I have a rooted Nexus 5 (5.1.1). It doesn't have a custom recovery whatsoever, it's only rooted using Nexus Root Toolkit because I'm so lazy

Now I've received an OTA system update.

So the question is, can I update it or will it fail, or even worse, brick my N5 completely? I have read that these major updates will most likely fail on rooted devices.

Or should I just use NRT and upgrade it that way?

Any help is really appreciated

Welcome to our AndroidForums, Rousku.

The 6.0 OTA is more likely to fail to install since the cross-checks will likely see that one or more of the files involved in the rooting process does not match the stock/expected contents (see http://androidforums.com/threads/rooting-otas-and-bootloops-oh-my.938343/ for some background).

BTW, I'm going to move your thread over to the N5 root area

.

Cheers!

you can easily unroot it using the same tool. Get the update and then root it again if you want

Rooting is a little messy right now. Haven't tried it yet. However, Google has introduced a knew Knox-like security system and the kernel is in some way I don't entirely understand resists rooting. Currently, the way to root it is by installing a new boot image developed by Chainfire or use a modified stock kernel like Elemental X, then you can root with SuperSU 2.5. I'm sure NRT will figure out a way to incorporate Chainfire's method or some such, but it is disappointing to see Google making it harder to root a Nexus device.

^^^ Yeah, I'd almost wait until Chainfire's had more time to look at not needing to have/use a modified boot image (i.e., "just" root using a flashable UPDATE-SuperSU-v#.##.zip file). This is pretty much where things were at the start of the 5.0 release regarding root (i.e., initially needing a modified boot.img file).

He's just recently gotten back from being away most of the summer and probably needs more research/debugging time.

If a modified boot.img file is needed, that's certainly going to limit the number of users & devices that will be able to fully root.

Why not just flash twrp and flash 6.0 rooted rom?

Because they don't exist yet?

Still a bit early in the game. Right now all you can do is use one of the 6.0 kernels that are available, including Chainfire's. The ROM makers will probably take some time to figure the best approach.

Another question. Although I thought I had locked it when I went back to stock 5.1.1, my bootloader is unlocked (so if everything else is stock, that apparently doesn't keep the OTA from working). Luckily the Nexus 5 doesn't apparently have the dm-verity warnings when booting, but should I lock the bootloader until I decide to root. I really would rather not since I don't want to redo everything. Obviously the bootloader is unlocked when I'm rooted, so I'm not really concerned about security issues. Are there any other practical considerations.

scary alien · Oct 10, 2015

Yeah, the OTA doesn't care (or hasn't cared) if the bootloader is unlocked (or not) (no checks in the updater-script file that I've ever seen).

The only downside I can think of is that if you lost your phone, then a knowledgeable person could simply soft-boot a custom recovery to gain adb access to whatever you've got stored on your device.

For those of you who are into Wugs Toolkit, it is now nicely set up to root using Chainfire's method. Instructions here:

Worked like a charm.

I know, I know, I'm just too lazy to use fastboot... I know how to do it, really. :rolleyes:

Some custom roms for MM are
rooted and ready to go with a beta superuser installed using the current touch recovery.
(Lollipop recovery)

Right now, I'm kind of having fun with stock, rooted Marshmallow. Rooted using Chainfire's method, TWRP of course. I've deleted a lot of Google bloatware with TiBu, themed it using layers and changed the dpi to 420. So far I'm pretty happy and may keep doing this until Dirty Unicorns becomes available.
