SuperSU v2.27 BETA - no more kernel patches?
Posted on 2014-11-20, 144 comments, 842 +1's, imported from Google+/Chainfire

NOTICE: This content was originally posted to Google+, then imported here. Some formatting may be lost, links may be dead, and images may be missing.

This new beta may be doing away with the previously needed kernel patches on Lollipop.

I should warn you however that this method is more invasive, and has a higher chance of bootloops. Probably the highest-bootloop-risk beta in quite a while. Please make sure you have a backup before flashing it. In case of bootloops, reflash the system partition.

If you've previously rooted, keeping the old patched kernel will do no harm, but it will also not properly test this beta. I suggest you flash back your device's stock kernel.

Remember that I rely on all you enthusiasts to test and report back issues. I prefer the reports in the BETA thread on XDA rather than over here, but I will read them here as well. Please include your device, firmware details, stock or patched kernel, and the problem in detail, when you report something.

XDA has some background details in their portal article, for those interested in that sort of thing:

SuperSU BETA thread on XDA:

Again, official docs are coming in the next few days. Let's get this all fixed and tested first, though!

Chainfire on fire, just like Google with there updates, r5,r6,r7 ? Jokes apart, major success if this is successful :)

Rahil Bhimjiani commented on 2014-11-20 at 15:25:

Thanks a lot. and congrats on 200k followers

Hans-Georg Michna commented on 2014-11-20 at 15:27:

How about letting SuperSU detect boot loops and taking preventive action after a boot loop is detected, like trying different strategies?

Todd Yates commented on 2014-11-20 at 15:27:

The XDA article seems to be missing, can we read about it anywhere else?

Chainfire commented on 2014-11-20 at 15:33:

+Todd Yates check again... timing things across sites to the exact second is difficult, you know.

Todd Yates commented on 2014-11-20 at 15:34:

+Chainfire Ah, I was just flicking through G+ and didn't realise how new this post was, sorry.

+Todd Yates should be fixed

r k commented on 2014-11-20 at 15:39:

Just for the record, installed the stable version via the autorooter on N4 and N10 (both on Lollipop), works like a charm. I just don't get what's all that kernel patch fuss about.

Haris Huntic commented on 2014-11-20 at 15:47:

2.27 doesn't clear log

Carlos Rodríguez commented on 2014-11-20 at 15:48:

+rk fg The autorooter patches the kernel. +Chainfire intends to make a zip (he succeded) to avoid this and therefore it would work with devices with locked bootloader.

r k commented on 2014-11-20 at 15:49:

+Carlos Rodríguez Oh, thanks. Didn't know about that and didn't even know it's possible without recompiling.

Carlos Rodríguez commented on 2014-11-20 at 15:50:

+Chainfire aparently, everything works fine with 2.27. I flashed the stock boot.img and then booted to TWRP (when I'm on stock I don't flash a custom recovery, I just boot to it to flash SuperSU) and flashed 2.27. Wakelock detector and other root apps work.

r k commented on 2014-11-20 at 15:58:

Oh, so wakelock detector is broken because of this and the issue was fixed! I forgot about it, really. My other root apps work fine though, except WLD. Many thanks again.

王权 commented on 2014-11-20 at 16:04:

It works!I just flashed boot.img via fastboot,and after reboot I opened SuperSU to make sure I truly flash stock kernel. After that I flash 2.27 via TWRP,and it works!

George P commented on 2014-11-20 at 16:08:

i can confirm,it works for Motorola Victara.

Thank you Chainfire

Mr Chao commented on 2014-11-20 at 16:22:

+王权 请问这个商店更新要多久呢

Ted Fishman commented on 2014-11-20 at 16:24:

Will this change allow post 5.0 OTAs to pass modification checks so that OTAs could be sideloaded like in 4.x?

Aaron Gascoigne commented on 2014-11-20 at 16:27:

+Ted Fishman​, no 5.0 uses a block level update so if your system partition isn't exactly as it shipped. Flashing otas will fail.

Nicholas Daniels commented on 2014-11-20 at 16:29:

Works perfect here, stock kernel + non-rooted to stock kernel + rooted

Ted Fishman commented on 2014-11-20 at 16:29:

+Aaron Gascoigne So you'll have to first reflash system partition as the easiest method?

Aaron Gascoigne commented on 2014-11-20 at 16:43:

+Ted Fishman​​ on a stock device using verified block level updates. Yes reflashing the system partition assuming you had an unlocked bootloader would be the easiest way. 

Angad Deep Singh Sehdeva commented on 2014-11-20 at 16:44:

Works on nexus 5 5.0 with the stock boot.

+Chainfire​ flashed 2.27 and titanium backup stop working it keep saying I have insufficient storage space and I have over 3gigs free

Manolohd dholonaM commented on 2014-11-20 at 17:12:

I've put in my nexus 5 the stock 5.0 boot.img,  then i've flashed the beta 2.27 of supersu by the new recovery twrp so the system be working very smooth.

Chainfire you're irreplaceable, fast and relentless.

Ruben Perez commented on 2014-11-20 at 17:12:

Sorry for my ignorance: I have updated from Nexus 4 Lollipop stock + root SuperSU 2.19 using NRT. After that, I have updated to SuperSU 2.23 Beta using de APK, (AutomateIt Pro root tasks still doesn't work), after then, update to 2.25 Beta in the same way (APK), and AutomateIt works fine now with root tasks as enable or dissable airplane mode. It is safe to update do 2.27 using the same method (APK)? I am not sure reading the heading of this post.... Thanks.

Works fine here with stock boot.img many thanks

Michael Zanette commented on 2014-11-20 at 18:17:

Is flashing back stock kernel, flashing boot.img through fastboot?  I originally rooted using AutoRoot so I assume my kernel is patched.  Will flashing boot.img give me stock kernel?

Jason Pasch commented on 2014-11-20 at 18:19:

Nexus 5 ,LRX21O factory images /TWRP recovery + Franco kernel r68, superSU v2.27 seems to be working as it should, +Chainfire​ should I have re flashed the stock boot images to revert changed to the ramdisc or is this not needed as I'm running a custom kernel?

Michael Zanette commented on 2014-11-20 at 18:23:

Flashed boot.img back, using 2.27 everything seems to be normal.  Tried root permissions with Tasker/Secure Settings, ES File Explorer, no issues

Thiago Galvão de Paula commented on 2014-11-20 at 18:33:

ANyone try this on the Nexus 6? I am about to.

Anas Ahmed commented on 2014-11-20 at 19:37:

Hi. I am having trouble downloading SuperSU beta! The download speed drops to "0" and stays like that for like an hour!!! Why is that?

Алексей Сычев commented on 2014-11-20 at 19:41:

N5, N7 2013 - worked fine after boot.img restore.

Frank Gambino commented on 2014-11-20 at 19:58:

Works perfectly with the Nexus 6. Thank you!

Derek Wyman commented on 2014-11-20 at 20:01:

So..I am on a stock/rooted N5 (4.4) best method would be?

  1. update to 5.0 (ota)

  2. unlock/wipe

  3. install twrp

  4. flash SuperSU 2.27

Ryan Houseman commented on 2014-11-20 at 20:01:

Yep worked on my Nexus 6 as well +Frank Gambino. +Chainfire you are the man bro!

Nexus 5, latest 5.0 factory image, bone-stock kernel.

I installed 2.26 yesterday, but I didn't realize that I needed to flash a new kernel. Just flashed this on top of 2.26 and it works perfectly. Tested with root checker and Amaze file manager and both recognize root access!

This. Is. Amazing!

Artem Russakovskii commented on 2014-11-20 at 23:29:

+Chainfire You're the absolute man! Worked great on fully stock N5 with Lollipop, stock kernel.

Hi ChainFire,

I rooted my N4 with Lollipop using NRT.

So now I have a modified kernel and I'm running SuperSU Pro 2.19.

What is the best way to update?

I think it is:

  1. update SuperSU to 2.27 using TWRP

  2. flash stock kernel

Is it ok?

Reneval Tupinamba Junior commented on 2014-11-21 at 12:00:

Nexus 7 2012

Android 5

was rooted by CF-Auto-Root

I restored the boot.img and rooted my device with this version.

no problem here and now I can disable startup apps in "all in one toolbox"

Mephisto Murau commented on 2014-11-21 at 14:29:

Workes fine on Nexus 9 with TWRP & lrx21r

Chris Reynolds commented on 2014-11-21 at 16:18:

Just wanted to give my feedback - I installed it via TWRP on my Nexus 5, running Lollipop and stock kernel.  Work great so far and I haven't encountered any issues.

Spiridon C. Dalietos commented on 2014-11-21 at 16:48:

Confirming, Nexus 5 stock boot.img flashed with SuperSU 2.27 and everything rolls beautifully! Great Thanks +Chainfire

+Chainfire​ v2.27 working fine on N6 except my LG G Watch, Android Wear says connected, running sync loop. Doesn't seem to affect anything though. I'm pretty sure this occurred after this flash because when I first setup it was not there.

Note 4 (sm n910k - 4.4.4 KitKat, ART runtime). Just installed this version and it fixed a number of problems with various apps with ART. TB now works and I can freeze and uninstall apps. I can also change screen resolution now which also wasn't working with the old version. Nice work CF! I was going to change back to Dalvik but now I will stick with ART.

N5 Lollipop full factory load + CF autoRoot.

Loaded this over the top via TWRP. No issues so far.

Robert S. commented on 2014-11-23 at 00:01:

Tried flashing this with TWRP and it gives an error about unable to open the zip. Tried downloading again same error. I'm on an HTC One m7 with CM12.

Anyone know how to get this working?

Edit: Looks like the download link in the XDA thread is corrupted. I had to download from the link in the op.

Mark Williams commented on 2014-11-23 at 04:31:

+Ray Darbin​ did you try to reflash the noforceencrypt_boot.img after CFAR, then factory reset in bootloader (fastboot format userdata)? My path was oem unlock, back to bootloader, flash noforceencrypt, reboot bootloader, format userdata, boot to OS, back to bootloader, flash twrp, flash CFAR. Win! (iirc)

Mark Williams commented on 2014-11-23 at 04:37:

Good luck!

Mark Williams commented on 2014-11-23 at 04:52:

No, 2.23. But you have to factory reset after flashing the noforceencrypt img, prior to booting the device into android

Mark Williams commented on 2014-11-23 at 04:58:

+Ray Darbin​ the thought was, if this version doesn't modify the kernel you can gain root, then unencrypt with the other script after installing

Mark Williams commented on 2014-11-23 at 05:00:

Yes, just don't use "erase userdata". Use format userdata as it cleans the partition, not delete it ;p

Mark Williams commented on 2014-11-23 at 05:14:

+Ray Darbin​ did it work?

Mark Williams commented on 2014-11-23 at 05:15:

Bedtime. I'll check tomorrow. The Boss here may have a better way ;p

Mark Williams commented on 2014-11-23 at 05:28:

Check with +Chainfire​, there has to be a way to do both. 2.23 working perfectly here on N6 with encryption off, stock n rooted with twrp. Nite!

Appreciate your work.

Winston Wang commented on 2014-11-23 at 10:38:

+Djcarwyn Harris​ I suggest you to flash the stable SuperSU v2.16, no need to flash a beta. You can flash it with the latest twrp recovery by going to Install->select ""->swipe to flash->reboot system

+Lennard Gäher +Chainfire  How did you get this to work on a N10 with stock boot.img?  I've clean flashed my N10 twice now, flashed the newest TWRP, and then loaded the zip.  

Each time, when the tablet boots, it tells me SuperSu has crashed and I only have the Android icon in my launcher called eu.chainfire.supersu.Mainaction.  Am I missing something here?

Chainfire commented on 2014-11-24 at 19:38:

+Matthew Fura there's something wrong with TWRP Use instead. Next ZIP update will work around this issue.

Matthew Fura commented on 2014-11-24 at 19:41:

+Chainfire I thought that might be the issue. Flashed the older 2.8.1 and tried flashing again, didn't work. Looks like I'll need to reload the factory image once more and use the older version. I'll let you know if that works.

Matthew Fura commented on 2014-11-24 at 21:15:

Thanks +Chainfire​. That worked.
