Holy wall of text, Batman!

Time for a 'stable' SuperSU update! There have been quite a few beta releases the past few months, with lots of under-the-hood changes, lots of bug fixes, lots of compatibility additions, etc.

AOSP/L

Again, a fair amount of work has been done to keep SuperSU operational on the latest AOSP builds, as security-related changes to AOSP are likely to end up in retail L. The changes are quite extensive and a departure from previous strategies to keep SuperSU operational on AOSP. As a side-effect of this, it may ultimately actually increase compatibility for root apps between different Android versions (and be less work for root app devs to support), as if it ends up working well on L, I will back-port these changes down to 4.2. It should be noticed that these patches are already in-use and tested against 4.4.

Cryptic and unspecific, I know. I will write about these things in detail once L is released (any day now?), if I don't have to revert them.

So what are the chances of this working on L at release? If we're lucky, the CF-Auto-Root's for  the Nexus devices will work out-of-the-box, but there's no way of knowing yet. There are dozens of things that could still go wrong, in fact, I have some concerns that ultimately we may need to have modified boot.img's to have root at all. We'll see when we'll see!

One thing I can tell you is that OTA survival mode will be very unlikely to work between 4.4 and L, at least initially.

Architecture specific binaries

SuperSU now comes with architecture specific binaries for: arm (v5), arm-v7a, arm64 (v8a), x86, x64, mips and mips64. The 64-bit variants are officially supported from L onward, so obviously they have not been tested on production devices yet.

CF-Auto-Root currently still always installs the arm (v5) binaries. "su -h" will display the specific version you are using.

Amazon

Amazon now distributes SuperSU as well, but their vetting process is more extensive and much slower than Play, so expect Amazon releases to generally lag behind Play releases.

Android TV

Aside from adding the CF-Auto-Root for it to my extensive list, this version of SuperSU brings some minor but much-needed improvements that just make it behave significantly better.

Cleanup

SuperSU now cleans up leftover packages from the root list at boot (if re-authentication is enabled). While this really is a minor thing, I want to point it out explicitly because on some devices and Android versions, if you move root apps to the SD card, this cleanup will be performed before Android has scanned the SD card for the apps. So from the perspective of SuperSU, these apps do not exist, get removed from the root list, and well re-request root access when run. 

A proper solution is still under investigation, and it does not happen for me on any of my 4.4 devices. Either way, if you find apps are losing root access on reboot, a work-around for now is turning off the 're-authentication' feature. Please do report this and your device and firmware details to the SuperSU threads on XDA if it happens to you.

Rollout

The latest (stable) flashable ZIP is available from http://download.chainfire.eu/supersu as always. All CF-Auto-Roots have already been updated.

I will update Play tomorrow, assuming no showstoppers are found by those flashing the ZIPs, which will probably be a staged rollout. So best-case scenario, everyone should be updated come Monday.

Special thanks to all the beta testers

Flashable ZIP

For the modders and exploiters amongst you, I have added some documentation to the update-binary script. It's not complete yet, and there are a number of changes and improvements I still want to make, but I'm sure it's more helpful now than it was before.

CF-Auto-Root

There have been a few changes to the CF-Auto-Root installer as well. One noteworthy one is that in preparation for L having encryption enabled by default, it no longer touches /data. This is both good and bad.

The good is that it doesn't need to know your decryption key, the process remains automatic, and encrypted phones are no longer wiped on usage of CF-Auto-Root.

The bad is that this means some /data cleanup code is run on first boot after rooting, which may trigger a (one) reboot in the process. I do not expect bootloops because of this, it works fine on all the devices I have tested it on, but you never know.

Additionally, because CF-Auto-Root cannot distinguish between a garbage and an encrypted partition, it no longer fixes OEM unlock issues. On several fastboot based devices, the OEM unlock command, instead of formatting /data and /cache, wipes them. Android will not automatically re-format them anymore (used to in 2.x days), which means that your device will forever bootloop until you manually format /data and /cache (which CF-Auto-Root did for you automatically in the past).

Last but not least, some changes have been made to allow the progress to be visible on some new Qualcomm based devices. While I would normally not waste words on something as trivial as this, I would like to point out that these devices no longer support fbdev to put content on screen, but instead use something called Qualcomm overlay. Nothing basically wrong with that either, aside from the absolutely horrid fact that the interface to this changes between different kernels in a completely incompatible way, pretty much requiring a userspace program to use the exact right version of kernel headers to do something as basic as putting anything onscreen. Making a non-kernel specific binary that support a wide range of devices is thus now nigh impossible unless some very ugly code and errorprone methods are employed. As such, I expect that ultimately there will be no visual progress for CF-Auto-Root anymore on Qualcomm based devices, as I certainly can't be bothered keeping track of these shenanigans.

Excuse me, i skipped this xD

Chirayu Desai commented on 2014-10-10 at 13:49:

+Chainfire, you could probably use setup_fs (system/extras/ext4_utils/setup_fs.c) to fix at least some of the OEM unlock issues, if not all.

This was last used by Google for Galaxy Nexus, and does work on Sony devices too (we're using it on all 2012+ devices supported by CM currently, which is all devices including and after Xperia T).

Chainfire commented on 2014-10-10 at 13:52:

+Chirayu Desai thanks, nice find. It's only a handful of devices suffering from this though, not exactly a priority.

+Chainfire  - 2.13 had issues on Galaxy S4. No luck even stopping the app, clearing the cache and restarting. Rolling back to 2.0 fixed the issue (App  and Log forever spinning). But rolling forward again (auto update in play) brought the problem in again.

A fault in update-binary in 'UPDATE-SuperSU-v2.14.zip' :

....

if [ "$API" -eq "$API" ]; then

if [ "$API" -ge "17" ]; then

SUMOD=0755

SUGOTE=true

PIE=.pie

It should be:

if [ "$API" -ge "18" ]; then

I think, Since Android 4.2 needs setuid/setgid flags to be set on su binary.

Jonathan Yee commented on 2014-10-17 at 18:26:

I rooted my Galaxy S5 back in May using Chainfire AutoRoot for the T-Mobile version, SM-g900t. Haven't flashed anything since; just wanted to have root access for a couple apps.

When Android 5.0 Lolipop rolls out to the Galaxy S5, how can I update my phone to that? Would I have to unroot, update to Lolipop OTA, and root again? (if so, would I have to find a different method of rooting or can I use the same Chainfire AutoRoot?)

Or is there a way to update to Lolipop without losing my root?

Rafael Mendoza commented on 2014-10-17 at 20:59:

Confirmed... Doesn't work with LPX13D 

Spiridon C. Dalietos commented on 2014-10-17 at 21:00:

+Jonathan Yee best way is to do clean install. Download your image from samfirmware, backup your data and update via Odin... Then root back again.

Jonathan Yee commented on 2014-10-17 at 21:05:

+Spiridon C. Dalietos If I have to root again, what method would I have to use? Assuming the firmware version is Android 5.0, would I have to find a root method that specifically works based on 5.0?

Spiridon C. Dalietos commented on 2014-10-17 at 21:09:

+Jonathan Yee the same way you rooted, via cwm or twrp, and yes, you will need root for 5.0

Jonathan Yee commented on 2014-10-17 at 21:11:

+Spiridon C. Dalietos Would a better method be for me to flash the 5.0 ROM (when it is released) using Mobile Odin? That way I can keep root?

Spiridon C. Dalietos commented on 2014-10-17 at 21:18:

Nexus 5 updated to lpx13d Lollilop just few hours before. I have tried su 2.0 for L, 2.01, 2.02 up to 2.14 with no luck at all... Keep getting binaries errors or installation errors via flash from twrp...

Jonathan Yee commented on 2014-10-17 at 21:26:

+Spiridon C. Dalietos What is that supposed to mean?
