[Q] Lost root and Recovery with TWRP after Update

Okay be gentle...
After the last update to JSSR15R I lost root and SU, doing the rebbot into recovery (vol down + power button) TWRP launches but when I select to go to recovery via the vol buttons and select it with the power button, all I get is the exclamation point android.
While I'm not a total idiot (debatable of course), is there a way to re-establish root and su without wiping off 15gigs of music and playlists and starting from scratch? Rooting the Nexus 7 (flo) the first time (at least for me) was a fight I eventually won, but for me it was a fight. tia Tutor

Same thing happened to me. I installed TWRP via goomanager. Then, I flashed SU update. Now I'm back rooted and going strong.

Like previous poster mentioned, just reinstall twrp and su.
Your bootloader should already be unlocked. Unlocking the bootloader is the only step that causes you to lose data.
Reinstalling twrp and su will not cause you to lose data, unless you had locked after installing them last time, and now need to unlock again to reinstall.

I reinstalled TWRP via the playstore but while it shows my directory file structure it won't install my copy of Update SuperSU 1.5.1.zip also I went to install goomanager but the descrription says you have to have root prior to installing.
As a sidenote while in TWRP if I go into rebooting the device none of the actions work except when I hit the "Bootloader" option the a error box pops up stating the option isn't available on your device. Tutor

Only way I know of to install TWRP is go to the TWRP web site and download it from there to your PC. You will find flash instructions on the web site.

Download Goo manager from Playstore. Choose Flash Roms, It will tell you that you need a custom recovery to do this and ask if you have one or would like Goo to find one. Choose find one for me and it will download and install TWRP 2.6.3.0. After said process is complete flash SU update. Profit..

Same happened to me, but I reflashed TWRP and root access... Just curious how come that never happened with Clockwork Mod recovery being lost after applying an update to the system on the old N7.

If you don't want to lose root or recovery, it is very simple.
Boot to twrp
Install OTA update.zip
Install SuperSU 1.55 update.zip (Prior to reboot, use 1.55 as 1.65 has issues)
You will maintain root and keep twrp if you do it in this exact order.

Can TWRP generally find the latest OTA update.zip on it's own?

Nope, download the ota manually and place on your virtual sdcard, then boot to twrp and select the file for install

installing through goomanager didn't work for me. It would say it installed but wouldn't really install. I did it using the fastboot method instead and that seemed to work fine.

Well nothing I seemed to do would allow me to re-root the Nexus 7 after the 15R update, I finally went as re-rooted from scratch using the sticky post at the beginning of this subdivision forum for the Nexus. Back up and running in root and su... thx to all those that attempted to help me thru this

I used Wugfresh tool. Everything worked until I flashed the updated SU 1.65. I could never get root. I read earlier that others were using SU 1.5, so I manually went back into TWRP and flashed SU 1.5 and bam, had root! Then SU upgraded itself via the play store to the newer version. Go figure!

The update.zip for SU 1.65 is broken. A "placeholder" install script was included that does nothing.
IMO SuperSU 1.55 is the best version to use right now. The install script works, it doesn't mess with a bunch of file permissions for your *other* files in /system to support the new ota survival mode, and it has the fix for the problem that used to break the OTA installs.

Accidently flashed wrong SU binary, need help!!

My phone is a Huawei u8160 (AKA Vodafone 858) and I rooted it a long time ago with z4root and have had no problems eversince.... until recently when my mate got hold of my phone and accidently flashed an experimental/beta (possibly a binary for x86 systems) SU binary through CWM recovery. I thought I could fix this quite easily by using z4root to uninstall root and then do a fresh reinstall, but it would force close on me after a few seconds. I tried this method with both temporary and permanent root options but nothing worked. The button that pops up saying ''unroot'' wasn't there even though there is still a SU file in /system/xbin as it showed in Rom toolbox. I soon realised that the version of android i was running on my custom rom was not compatible with z4root, so i searched for how to root android version 2.3.9 pro. I dont know the name for that version and it must have been a bit of a flop because google didnt know it either. I dont know how akiro-E (the developer that cooked up the rom) got his hands on version 2.3.9 pro but i recommend to other devs reading this to not use it as there is not much compatibility.
Anyway, i found this apk made by chainsDD called gingerbreak and decided to give it a go. It said that it needed debugging on and that it might take a while, so i did that and pressed the root button. I left it to do its business, but 15 minutes later it was still trying to run the exploit so I stopped and removed it. When i got home later on i searched up how to root any phone and it came up with the pc program 'superoneclick'. I got it, opened it and clicked unroot. It did its thing but failed to remove su and the superuser app like it was meant to. So then i clicked on root and shell root but it did not reinstall properly and got the same error as in unroot error. I did all the steps multiple times but it still wouldnt remove/replace su from the xbin folder. I then reinstalled superuser 3.1.3 and tried using the binary updater on there. I noticed that the su installed was called 'legacy'. The updater was having a spaz and didnt want to update so i tried manually removing su with the root explorer in rom toolbox butvrealised that you needed root (a working one) to do that. Then i found an app on my sd called root cleaner. I tried quick and full cleaning but to no results except for a force close multiple times. I tried to fi the foce close issue by running the script for this in rom toolbox but you need root (surprise surprise) Then i tried flashing cwm recovery through fastboot as i have done lots of succesful times before. It flashed after putting my phone in download/debug mode (power and volume down) but i cant boot to it as you need proper root rights to do that.
I am going to use total commander to check if the permissions are set to 644 for the su binary, if not ill attempt to change them.
I know this a long desciption and technical question but does anyone know any ways to delete the retarded root from my phone and help me restore root as normal? This is a question for the more experienced users and devs on this forum but any help will be appreciated, cheers.

If you've got recovery, you can install one of these zips in recovery mode.
Google "superuser 3.1.3 arm signed zip" and click the first link that comes up - the androidsu one. Then download the superuser zip package that suits your device to your phones internal storage, reboot into recovery, install the zip and there you go! Your root is fixed.

@odigITECH thanks for the help. I fixed the problem using your method. . . kind of. I flashed recovery via fastboot and then just flashed another rom from my sd card via cwm after I rebooted. Thanks for the help anyway, much appreciated!

No probs

[Q] Official CyanogenMod and root

Hey all,
Just installed the Official Cyanogenmod on my N1 and lo and behold, root has run away.
ROM here: cyanogenmod(dot)org/hardware/oppo-n1/#images
I installed the TWRP Recovery and tried to let it install Root and it appears that it sort of does with the SuperSU app, but other root checkers and Titanium fail hard on this.
Anybody got any ideas on how to root Cyanogenmod? (Just sounds weird to say that)
Thanks
Tal

I had to flash SuperSU in recovery. I encountered the same issue. TWRP didn't root, even though it said that it did. Updating SuperSU within android didn't help. So I flashed it manually.

When you say flashed it manually. Was that through fastboot? ADB? or from the recovery.
Also, are we talking about UPDATE-SuperSU-v1.86.zip from download.chainfire(dot)eu/supersu
I tried that through recovery and still get /system/xbin/su command missing in Titanium.
Thanks

Ok good News, what I mentioned above through recovery works just fine.
Issues:
Remove all previous instances of it from OS (from inside the SuperSU app, select Switch superuser app or Unroot)
WIPE DALVIK CACHE!!!
Hope this helps others.
Thanks

[Q] Cannot obtain Root....

I've been toying around with my new Verizon HTC One (m8) and decided to permroot earlier today (I've had temproot via weaksauce for a month). This took me forever because the only s-off and bootloader unlocker that would work (after hours of trying firewater and HTCdev) was Sunshine. I eventually paid for it and tried to root. I installed CWM at first but didn't realize that Supersu had to be present on my sd-card, so I rebooted. I then flashed TWRP over CWM and tried to root with it instead. Unfortunately, I had downloaded Supersu off the Play Store and (of course) didn't achieve root from the bootloader. That was a few hours ago.
Now I'm stuck with TWRP and no matter what I do, I cannot figure out how to root. I've flashed 3 different versions of Supersu from recovery and none of the zips I install offer me the option to root. I've tried to flash Supersu through adb sideload. I've even tried using ROM manager to reboot and install a copy of Supersu downloaded off my phone's Chrome (probably didn't work because I'm not rooted - it tells me "an error occurred while trying to run privileged commands").
I was under the impression that after installing the Supersu zip from recovery, you would be asked to root either directly after installation or upon rebooting. However, when I reboot, TWRP warns me that "There is no OS installed, are you sure you wish to reboot?" From what I've read, that normally indicates a soft-brick, but my phone is definitely not bricked (yet).
How can I flash Supersu in a way that gives me root?
I'm fairly competent with adb, but nowhere on the internet have I found a problem even remotely similar to mine....

Are you able to boot into twrp and which version do you have? Twrp will automatically ask if you want to install the su binary the first time you reboot from within twrp.
When you reboot you should see the supersu app. All you need do is update it via play store.

I downloaded and installed the Root Kit from recovery. It said install successful, but below that it said "Unable to mount /system." When I rebooted, I still didn't have root and Supersu hadn't downloaded. Do I need to do an ruu and just retry everything?

I can boot into twrp, and it's the most recent version from their website (for the Verizon HTC One). For some reason, it didn't ask me to install the su binary the first time I rebooted, and now I don't know how to do it.

SuperSU on CM13

Hey all. I just flash that ROM. Works really nice. But I can't find SuperSu installed. Also apps which needs root permission didn't worked. I just go do download SuperSu from market and the program shows me an error told me to reboot and try again. Can you please help me? Thanks in advance.

You ALREADY HAVE root with CM-SU. To enable it, just go to developer option and give root permissions to app. Some SuperSU's versions are incompatible afaik. CM-SU preinstalled is just fine.

SuperSU is an issue for itself. Installing 2.74 using TWRP on my G3 lead to boot problems because of a boot image patch that SuperSU installs. If I restore boot partition before rebooting, SuperSU doesn't install. Using Play Store version fails to install su binaries.
Conclusion: use CM own root. It works nicely, just lost FolderMount but, well, I prefer that instead of losing phone.

Have you try this method http://forum.xda-developers.com/lg-g2/general/bump-supersu-t3273251
CustomPatcherScript_Bump.zip + UPDATE-SuperSU-v2.65-20151226141550.zip
But it's also can cause reboot loop
Do backup before doing flash that script
That worked fine with my D855 32Gb + CM13
