[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.

[Q] N7 LTE root won't stick

I've unlocked the bootloader, installed TWRP and have been trying to install SuperSU v1.65 (and 1.55 previously) but when I tell TWRP to reboot into Android it tells me I don't have root and asks if I want to root. No matter my answer, I cannot get the tablet to boot with root access. Any ideas? I've even tried Wugs Toolkit and SkipSoft's toolkit and neither does the trick. Help!

Hmmmmm.... I skipped the install superSU after I had TWRP because from there I just flashed AOKP.
What are the exact steps you've done?

Yeah, I thought about just going for a ROM with SuperSU baked in but am still not sure as I'm testing out Paranoid Android on my N10 still. Normally, I just flash a ROM immediately, I've never tried to root and run a stock Google ROM before.
Anyways, I unlocked the tablet immediately as to not lose information once I decided to root and ROM. I had the tablet for about a week before deciding to root it, so of course all the USB Debugging, USB drivers, etc. stuff was already done. Then I:
downloaded CWM recovery to PC
copied SuperSU 1.55 to the root of the sdcard (later on I switched to SuperSU 1.65)
fastboot oem unlock'd it
fastboot flash recovery'd latest CWM
rebooted into recovery
flashed SuperSU
rebooted into Android (this is when I get the "you're device is not rooted..." dialog)
Once booted, root access is not allowed, so I flashed TWRP via fastboot and still couldn't get root. I tried both recoveries several times each. As mentioned before, I have tried both telling CWM/TWRP to root the device and not doing so, but neither way allows me to keep root. This is when I tried SkipSoft and Wugs Toolkits. Both said they rooted the device but I got nothing.

Did you update the su binaries once you booted?

Well, SuperSU is nowhere to be found on the device once it boots, so no. I did try installing SuperSU from the Play store and it warns me that the binaries are not updated but then immediately closes and doesn't let me update them (I'm guessing its because I have no root access).

That is odd indeed. Try downloading superSU zip again. If TWRP says you don't have root and asks to fix, say no.

I still could not get superusersu installed Its able to flash over recovery fine but when rooting it says everything is fine but superuser never shows up and I dont have root access Thanks for trying I appreciate it

I had problems originally but I did like others. I downloaded the newest SuperSU 1.65.zip, moved it onto the N7. Booted into TWRP, selected Install and selected the zip. After that I rebooted from TWRP and I had root.

I am just trying to understand where things are going wrong.
I went back and did a fresh factory image of KRT16O wiping user data.
I then copied
http://download.chainfire.eu/346/SuperSU/UPDATE-SuperSU-v1.55.zip
to the virtual sdcard.
I rebooted to bootloader and started twrp using
fastboot boot twrp.img
Then I chose to install SuperSU 1.55 using the above file.
Then rebooted to Android.
The SuperSU app was in the app drawer and I could perform su from adb shell and it would ask for permissions.

After I installed the factory images, I rooted my device. I don't use toolkits, because I think they make thing more complicated that it actually is. It is best to learn ADB whenever you can. That makes rooting so much easier.
Before I entered the bootloader, I downloaded SuperSU v1.69 through Chrome.
I made sure that all drivers were installed and began rooting.
Since my bootloader already was unlocked, I just flashed TWRP 2.6.3.1 with fastboot using this command:"fastboot flash recovery openrecovery-twrp-2.6.3.1-flo.img" without quotes.
That went smoothly, afterwards I rebooted to TWRP and flashed the zip... There I was rooted.
SuperSU: http://download.chainfire.eu/365/SuperSU/UPDATE-SuperSU-v1.69.zip
TWRP: http://techerrata.com/file/twrp2/flo/openrecovery-twrp-2.6.3.1-flo.img
Hope this helped.

I just got root access! I found superuser in settings under apps but it would not show up in app drawer and would not give permissions to anything.I then disabled the updates back to superusers 1.55 and it showed up in app drawer and busy box asked for permission right away and root checker confirmed root access. Then updated through play store and everything is good now. Hope that helps

[ROOT] Marshmallow MRA58N systemless root

Hi, for those who want to root the latest Marshmallow build (MRA58N), I managed to do it using Chainfire new systemless root.
PREREQUISITE: unlocked bootloader, active usb debug, working adb drivers.
Thanks to user @Badgerkiller who used mra58k systemless to replace proper files in original mra58n for Fugu, otherwise the NP goes in bootloop due to Selinux policies (http://forum.xda-developers.com/showpost.php?p=63833541&postcount=2797).
Download fugu-mra58n-boot-systemless.zip from the post above and flash boot.img via fastboot.
Download also Chainfire SuperSU v2.52 from https://download.chainfire.eu/743/SuperSU/BETA-SuperSU-v2.52.zip and put it in the NP storage.
Reboot in recovery, flash SuperSU-v2.52 and reboot.
This worked for me, hope it helps!
Edit: Here is the systemless SuperSU-v2.56 from Chainfire post: http://forum.xda-developers.com/showpost.php?p=63197935&postcount=2

Have you rooted yours before? Im on MRA58N, first time trying to root this thing and my PC/Toolkit isn't allowing me to flash. Gives me an unauthorized error.

I'm going to test this, thanks.
I previously tryed both boot images (orginal and systemless) on the MRA58K without success ... but I was using SuperSU-v2.56 ... now I will try with v2.52 beta as suggested on your post ...
I'll report back later ...

The SuperSu you linked to is not systemless.

For me is the first time rooting my NP (just bought it a week ago and after frist boot NP automatically updated itself to Android MRA58N).
In order to make the NP visible to my Windwos 10 pc in adb mode and download mode, I had to install PdaNet (after that, WinDroid and SkipSoft toolkit works well too).

Thanks man, It was a pain as forgot to unlock the bootloader as well. But PDAnet worked great. I got in TWRP and flashed SuperSU, Both the 2.52 and 2.56 version but I am still not rooted, It says the binary is not installed, am I still doing something wrong?

This is exactely what I did:
1) Booted up my brand new Nexus Player;
2) The NP updated itself to MRA58N;
4) Once rebooted in download mode, I flashed TWRP recovery (via SkipSoft ToolKit);
4) Tried to root via SkipSoft ToolKit, but I got bootloop;
5) Then I booted in download mode;
6) Flashed original MRA58N image (via SkipSoft ToolKit);
7) Booted up the system, enabled Developer options and USB debug;
8) Rebooted in download mode;
6) Reflashed TWRP again (via SkipSoft ToolKit);
7) Flashed the boot.img contained in the file "fugu-mra58n-boot-systemless.zip", provided from user @Badgerkiller;
8) Rebooted in recovery mode and flashed SuperSU-v.2.52.

Root for Stock 6.0.1

From rooted 6.0, I took the OTA and was stuck. Finally wiped everything and installed 6.0.1 fresh. flashed TWRP and supersu 2.60. But after boot, Supersu says binary needs to be updated - but fails to update.
TWRP works fine. Just can't root 6.0.1 with unlocked bootloader. Can anyone share the supersu that worked for 6.0.1? TIA

That wasn't my experience. I took the 6.0.1 update and it failed. So I ran
Code:
fastboot flash system system.img
fastboot flash boot boot.img
using the system and boot images from the 6.0 update. And then I waited for the OTA again. It installed ok.
Using TWRP I installed SuperSU 2.60 for a systemless root of the boot image. Everything is fine.

i can't even get pass installing twrp. every time i flash twrp in fastboot mode it works but it wipes my entire device. booting into twrp shows "NO OS INSTALLED' and even the sd card storage is wiped. the only way to get it to boot is to flash back 6.0.1 full stock rom. any help???

Try nexus root toolkit.

WugFresh did not work for me, after booting into TWRP and looking for the SuperSU and BusyBox they don not show up. Below is a post I have over on WugFresh Forum.
I’m having the same problem as everyone else. I’m using 6.0.1 MMB29K. It goes through the motions but when TWRP launches the /sdcard directory is empty. However, when I reboot and look at the files using an app called File Manager, I see them in /storage/emulated/0/!ReadyToFlash/Root_Files/. However, if I use a app called Root Browser I see a directory called sdcard and in there is !ReadyToFlash/Root_Files/ so they are being copied to the tablet but when you go into TWRP to install them they can’t be found. I tried to use the app Root Browser and make a directory called kiledl, this failed, probably because I do not have root access. Kind of a catch 22 here. I was just going to copy the files in sdcard to my directory and then try again. NO go!!! Anyone else have any ideas? I seems like this is some sort of permissions issue with the files but only from TWRP. I sure hope someone comes up with an answer, WugFresh and ideas?

Download latest SuperSU 2.62-3.
Root via Nexus root toolkit.
Then copy SuperSu to nexus and flash, supersu not from NRT but downloaded latest 2.62-3, busybox and last rar.
Sorry for my English.

Found a solution, the version of TWRP that WugFresh NRT is using is not compatible with this version of the N7 seems as though these were made with a different MMC memory. Check you this link and download this modified version of TWRP. You can use the NRT Advance Utilities > fastboot flash > recovery > other and then point to this modified version of TWRP and install it. Then you can proceed with the install of SuperSU and BusyBox. They will show up in the !ReadyToFlash/Root_Files/ folder to install.

noooo. That's not true. I just used NRT yesterday to upgrade to rooted 6.01.
EDIT: I think I misundersstood your post. This is only a problem if you try to install TWRP when upgrading right? If you just want to upgrade to 6.01 and keep stock recovery there is no issue.

Yes it is true, it depends on what kind of eMMC chip is in it. I have a very new device and NRT would not root it. When it booted in TWRP it could not see the !ReadyToFlash/Root_Files/ folder to install the files. There was no files on SDCard at all unless you booted to Android to verify they were in fact there. I had to install the modified Recovery TWRP file first. Saying "noooo. That's not true." is a little harsh, kinda make me a liar, I think NOT. Just because the method worked for you does not mean it worked for me. Not all devices are the same. If you read other post here you will see lots of others are having the same problem.

Correct only when using TWRP. However, I was using WugFresh NRT and it does a temporary install of TWRP then you install the SuperSU and BusyBox files. However, with the wrong version of TWRP you would not see the files in the SDCard folder, it would be empty. However, booting back to Android and using File Explorer the files where there. Using the modified version of TWRP would correct this.

interesting. i was wondering why some persons say it work and when i tried it, it wouldn't show anything in twp. can you point me to the link of the modified/correct version of twrp to use or help me by saying what to search. i don't want to sound lazy bu asking you for the link but i'm not sure as to what to google exactly to find the correct twrp to use. obviously i've been google wrong the pass few days because that hasn't come up for me in any of my past searches
Update: i found it and it works. thanks guys. now i can flash some custom roms. gonna try cm 13 tonight. thanks again

You most have the same unit as I do. I just got mine a week ago from GroupOn as well.

i bought mine about a week ago off amazon. i had a gift card and had nothing to buy so i decided to get the N7 and give it a try
