SuperSU v1.43 released

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 is mostly a bugfix release for Android 4.3. 

The CPU spike thing should be resolved. At least, the cases I was able to reproduce have been fixed, which does not mean there may not still be different cases out there that can cause this behavior. If you run into it, please let me know. The origin of the spike is root-using apps closing the su session in new and unexpected ways (some devs are really inventive with this).

The su binary for the moment also symlinks /storage/emulated/<uid> to /data/media/<uid> . This might fix some issues with some apps. However, the authors of said apps should still put the time in and fix this properly. This is a temporary(!) band-aid solution. I will post some more about this problem and mounts in general in a separate post aimed more at techs and devs.

I do recommend an upgrade to this version if you are currently on 1.41, as no root app dev will want to deal with the quirks of 1.41 in daemon-mode for the long term.

Also, please note this release actually breaks Triangle Away (update ASAP), and may break some other things that might use install-recovery.sh to do magic. That sucks, but until we come up with a better way of installing this, that's how it's going to be. If you're building a custom ROM, you should replace the install-recovery.sh method of launching the daemon with a proper init service.

Download

The TWRP flashable ZIP is here: http://download.chainfire.eu/342/SuperSU/UPDATE-SuperSU-v1.43.zip

If you're using a recovery that asks you if it should disable flashing the stock recovery, answer no.

EDIT#1: CF-Auto-Root's for Galaxy Nexus, Nexus 4, Nexus 7 and Nexus 10 have been updated with SuperSU v1.43 for Android 4.3 - http://autoroot.chainfire.eu/

EDIT#2: SuperSU has been updated on the Play Store (will take a few hours to propagate), but if you're going from 4.2 to 4.3, you still need to re-root "manually" by using the ZIP file or CF-Auto-Root. Just updating the app is not enough to make 4.3 work.

Thank you.

Torsten Meyer commented on 2013-07-25 at 21:43:

It finally works :) Thank you so much!

Jonathan Berry commented on 2013-07-25 at 21:44:

I just had the CPU spike thing happen. You mention the zip is TWRP-flashable, does it also work in CWM?

Torsten Meyer commented on 2013-07-25 at 21:46:

+Jonathan Berry I flashed it using CWM. Works fine. Just answer "No" if asked to disable flashing the stock recovery after selecting to reboot the device.

Rodrigo Araneda commented on 2013-07-25 at 22:02:

Thank you so much Chainfire, testing in Nexus 4 with Stock Deodexed JB 4.3 ...

Alex Willis commented on 2013-07-25 at 22:02:

Question: how do I install TWRP on Android 4.3? Can it still be installed through goo manager?

Fernando Raya commented on 2013-07-25 at 22:04:

Thanks!!! Not work on cmw?

Torsten Meyer commented on 2013-07-25 at 22:05:

+Alex Willis Just by using fastboot flash recovery openrecovery-twrp-2.6.0.0-grouper.img

Torsten Meyer commented on 2013-07-25 at 22:07:

+Alex Willis Either run cmd.exe (if using Windows) oder enter Terminal (if using Linux). Then type fastboot flash recovery openrecovery-twrp-2.6.0.0-grouper.img

Maybe you first have to download Android SDK from Google.

Alex Willis commented on 2013-07-25 at 22:14:

Is grouper nexus 7?

Torsten Meyer commented on 2013-07-25 at 22:14:

+Alex Willis Yes, the wifi model.

Alex Willis commented on 2013-07-25 at 22:16:

Thanks for help +Torsten Meyer

Martin Born commented on 2013-07-25 at 22:16:

Thank you very much! Updated my Nexus 4 via Factory Image to 4.3, installed TWRP, SuperSU and BusyBox and everything runs smoothly. 

Keep up the great work! 

Stephen Cowley commented on 2013-07-25 at 22:21:

You've done it +Chainfire . was having the CPU issue with 41 version but 43 via twrp has done the job. All rooted on 4.3 here. Thank you. Nexus 4 btw.

Julio Lagara commented on 2013-07-25 at 22:27:

Thanks man! Amazing job as always! Noticed it said TWRP flashable zip. Will it work with CWM as well?

Jorge Jobim commented on 2013-07-25 at 22:40:

Thanks, worked perfectly in my Gnex.

rei luna commented on 2013-07-25 at 22:40:

Peter Richard commented on 2013-07-25 at 23:04:

Thank you, all done

Bryan Guerrero commented on 2013-07-25 at 23:07:

Thank you so much! I needed this badly since many kernels are already 4.3-updated but their control apps needed root!

Artem Russakovskii commented on 2013-07-25 at 23:15:

+rei luna Yes.

rei luna commented on 2013-07-25 at 23:25:

thanks. i didnt have any problem with 1.41 but i flashed the update anyway. looking good so far.

Ziggy Winnicki commented on 2013-07-25 at 23:47:

Hey Chainfire or anyone, what's the best way to root? Is cf-auto root the best option?

Chainfire commented on 2013-07-25 at 23:53:

CF-Auto-Root's have been updated!

Ziggy Winnicki commented on 2013-07-26 at 00:00:

+Chainfire so first cf-auto root, then twrp then supersu?? Do you use Odin to flash cf-auto root like on the Samsung galaxies? Sorry mate first time nexus user.

Chainfire commented on 2013-07-26 at 00:03:

You only need to root once. If you've already rooted, you don't need to root again. So if you've used the ZIP, you don't need to use CFAR, and vice versa.

Ziggy Winnicki commented on 2013-07-26 at 00:05:

+Chainfire so the attached super su includes root, right?

Gustavo Adolfo Del Castillo Velarde commented on 2013-07-26 at 00:09:

Thanks, i only install this zip whit cwm. Working on nexus 7 3g

Eli Fonseca commented on 2013-07-26 at 00:21:

+Chainfire Fantastic. Thanks.

Ziggy Winnicki commented on 2013-07-26 at 00:36:

Thanks chainfire, all good here

Chad Muszynski commented on 2013-07-26 at 04:21:

If I've already rooted using the 1.41 beta previously posted, can I simply update through the Play Store?

김진서 commented on 2013-07-26 at 04:41:

Thank you

Goran Galic commented on 2013-07-26 at 04:54:

Works on my GNex now as well, epic :-)

Fitzelgard Misledz commented on 2013-07-26 at 06:06:

Works as intended with the Nexus 4. Kudos to you Chainfire!

Yue Ma commented on 2013-07-26 at 06:18:

Mine shows 1.44. Is it right?

Hoder Jensen commented on 2013-07-26 at 07:24:

v1.44 is latest from the play store, so that's perfect.

Thanks for the new version, works perfectly.

boonsattha mahamongkol commented on 2013-07-26 at 07:38:

Thanks

Bedjam Rivera commented on 2013-07-26 at 09:04:

When I tried to flash the zip TWRP said it couldn't open the zip file. Any help?

Kris Weiser commented on 2013-07-26 at 09:09:

I just updated in the play store to 1.44. Does that sound right?

Marhensa Aditya Hadi commented on 2013-07-26 at 09:15:

yes, playstore already 1.44, is it safe to update from playstore from this zip?

Stephan Schmitz commented on 2013-07-26 at 09:55:

Yes, it is safe to update to 1.44 (at least in my N4). Here's a flashable zip of 1.44 - including a modified updater-script to ensure to also remove old apks that were installed in /data/app: https://plus.google.com/110937633080014620803/posts/795g2Jy1AX3

Jason Minnis commented on 2013-07-26 at 11:58:

Sorry, but I'm unclear on the Triangle Away issue. It the issue present in the newest release? Should I just not use triangle away for now?

Steve Rodrigue commented on 2013-07-26 at 12:27:

Merci +Chainfire!

Ça marche.

David Flamand commented on 2013-07-26 at 14:49:

I have an issue, I dont know if i'm the only one that use su from command line but when I execute su it's impossible to return, e.g. with exit, the proccess get stuck. Even 'su -h' get stuck. Same behaviour for v 1.41 1.43 1.44.

EDIT: seems ok from adb shell but not from Terminal Emulator

EDIT2: the issue only occur when using a shell other than /system/bin/mksh

Stephan Schmitz commented on 2013-07-26 at 15:06:

+David Flamand Have you tried installing the Zip that I posted here: https://plus.google.com/110937633080014620803/posts/795g2Jy1AX3 ?

Joe Philipps commented on 2013-07-26 at 15:52:

So...I'd like you to make a prediction, if you have more experience with it: When my Nex7 nakasi 4.3 update eventually gets here, would I have to do anything, or do you think it'll be operational after it's done?  I have the donate version, so I have engaged "protect root against OTA update" (or whatever it's called).  No big deal if it DOES get crunched, I leave my bootloader unlocked, and all I'll have to do is download your update zip, boot TWRP with fastboot, and do adb sideload.  But I'm just curious about what my expected experience will be.

hassan elkahlaoui commented on 2013-07-26 at 16:50:

I cant root my s3 using Android 4, 1, 2 ?

Joshua J. Drake commented on 2013-07-26 at 20:24:

Thanks for the mention +Chainfire =)

Carlos Rodríguez commented on 2013-07-26 at 22:02:

Any chance to get the .zip fot 1.44 +Chainfire ???

Stephan Schmitz commented on 2013-07-26 at 22:26:

+Carlos Rodríguez  If you don't mind that it's not packed by Chainfire..

I unzipped the 1.43 Zip from his server, removed the Apk, added the 1.44 Apk (that I pulled from my device after SuperSU was updated via Play Store), added a few lines to the updater-script to remove existing Apks in /data/app (Btw, why is this not in your updater-script, +Chainfire!?), zipped it again and signed it. 

Here's the flashable Zip of 1.44: http://d-h.st/Hhw 

Note: Same as usual. When installing through CWM, make sure to select "No" when CWN asks you to prevent stock recovery flash!

Salvatore La Bua commented on 2013-07-26 at 22:30:

Titanium Backup still doesn't work for me, it doesn't even start, so I can't change the backup path as described in other comments.

It just says: Unfortunately, Titanium Backup has stopped.

Anyone else?

Ivon Liu commented on 2013-07-27 at 00:14:

In settings > developer options > show cpu usage, it used to constantly have "su" show up in v1.41. Glad to report that it's gone now in v1.43/44, likely due to the fixes to su daemon. Also not sure if placebo, some of the lag in 4.3 (quick settings, recents, etc.) have lessened and in the case of notification to quick settings, completely disappeared. 

Jeremy Piguet commented on 2013-07-27 at 03:13:

Is it possible to flash this by renaming it to update.zip in stock recovery on new Nexus 7 ? Don't have any PC to start via fastboot...

Stephan Schmitz commented on 2013-07-27 at 03:53:

+Jeremy Piguet I don't think it's possible in the direct way. Stock recoveries require the update.zip to be signed with the platform keys that were generated with your build (someone correct me if I'm wrong here). But what you can try..

1.) Download this zip: http://d-h.st/Hhw

2.) Install this Apk: https://play.google.com/store/apps/details?id=kellinwood.zipsigner2&hl=en

3.) Open the App and use the following values: http://i.imgur.com/tO0Oygb.png

4.) Click "Sign the file"

Now you can reboot in stock recovery and you'll see if it works.

Jeremy Piguet commented on 2013-07-27 at 04:46:

+Stephan Schmitz when I boot recovery, displays "ni command"

Stephan Schmitz commented on 2013-07-27 at 05:13:

+Jeremy Piguet Try to hold Power and press Vol-Up a few times. (Via http://forum.xda-developers.com/showpost.php?p=34696894&postcount=1 & http://www.androidpolice.com/2013/02/12/download-the-android-4-2-2-update-jdq39-for-the-nexus-7-and-nexus-10-right-now/#comment-799598041)

If that doesn't help, the other tip that I found requires a computer again. :-( Can't imagine why, but someone reported that connecting to N7 to the PC did actually solved the "no command" issue. (http://gametipcenter.com/how-to-hard-reset-the-google-nexus-7-tablet#comment-46982)

No answers for me :/ !!!

Thiago Oliveira commented on 2013-07-27 at 06:21:

No matter what I do, twrp won't root my gnex with 4.3. The installation goes ok, but after reboot supersu won't be there (and rootchecker shows no root is present). 

Phyo Lwin commented on 2013-07-27 at 06:55:

Any news about Titanium Backup crashing at launch?

Salvatore La Bua commented on 2013-07-27 at 10:18:

It works with the free market version of TB but crashes with the pro version.

Dominik Klöß commented on 2013-07-27 at 11:11:

can i flash the zip file via gnex toolkit using the sideload option without flashing a custom recovery?

不错，

John Wong commented on 2013-07-27 at 15:09:

Can I root my Nexus7 4.3, without wipe /data, (I want keep my /data and setting)?

I unzip the CF-Auto-Root-grouper-nakasi-nexus7.zip, and see the root-linux.sh, it do

sudo chmod +x tools/fastboot-linux

sudo tools/fastboot-linux oem unlock

sudo tools/fastboot-linux boot image/CF-Auto-Root-grouper-nakasi-nexus7.img

when it do oem unlock, is that mean my Nexus7 will reset factory default and the /data will lose?

thanks.

Salvatore La Bua commented on 2013-07-27 at 16:41:

+John Wong I think that the bootloader unlocking will make you force wiping in order to proceed, but you can use maybe Helium to backup your data beforehand. Also save the content of /sdcard.

Joe Philipps commented on 2013-07-27 at 22:07:

+Dominik Klöß, if you have set up your computer to use fastboot, yes.  You can use fastboot on your computer to boot an alternate image, such as TWRP.  You may need superuser permissions to access the USB port into which your device is plugged though (either Administrators group on Windows, or sudo or su access on Linux, not sure about Macs).  My computer is Linux, so I use sudo; if on Windows, you might need to do something like:

runas /user:administrator cmd

provide the password for Administrator, and run your commands from the cmd window that opens.

It's been a long time since I've had to do this, so details may be fuzzy.  The downside may be (here's where I do not remember well) that it may require you to unlock your bootloader:

sudo fastboot oem unlock

That, unfortunately, will wipe all your user data (the /data partition).  It's possible you may be able to back up (most if not all) your data with a non-root backup program such as Helium.  (I run Titanium, and that requires root, which would be a catch-22 for you.)

Assuming your bootloader needs to be unlocked and is unlocked, you can boot whatever system you'd like with something like the following (I downloaded the grouper (Nexus 7) image of TWRP):

sudo fastboot boot teamwin-recovery-grouper.img

So that means you don't have to flash Team Win to your recovery partition or anything; it just boots once.

Joe Philipps commented on 2013-07-27 at 22:11:

+John Wong, yes, the fastboot oem unlock step will force a delete/reformat/wipe of your /data partition.  If you don't have a backup, I might suggest Helium (formerly known as Carbon), which is a backup program not requiring root.  A lot of people seem to like it; I use Titanium personally.

It just occurred to me...why is it backup app writers seem to prefer chemical element names for the name of their app? 

pong Chong commented on 2013-07-28 at 02:25:

command write failed :( 

Mohit Virmani commented on 2013-07-28 at 13:57:

I updated to SuperSU 1.45 and after a reboot, I have lost root. No matter how many times I go into recovery and root the phone, I can't get rooted. I uninstalled 1.45 and went back to 1.43, that fixed the problem. (Nexus 4).

Giuseppe DM commented on 2013-07-28 at 14:03:

Doesn't work for me, SuperSU app stays stuck on loading, titanium backup waits forever during "Asking for root rights"... On Nexus 4, android 4.3
