I think failed rooting on N5 causes issues - Nexus 5 Q&A, Help & Troubleshooting

I flashed, unlocked and tried to root my phone with this guide:
http: //wccftech.com/flash-and-root-nexus-5-on-android-6-0-1-mmb29k/
Why I think rooting failed is that that I followed the guide through to the last step and after the last step clockwork mod said that rooting failed and I had two options to root or go back (but judging by the system messages the SU zip was installed). I think here I made the mistake to choose rooting "again". I read later in another guide but concerning twrp that this situation where the SU zip gets installed but the message says Installation failed a bug is and that I should not do what I did.
Anyway root was not achieved as I checked with the root checker app. The recovery mode now looks a bit strange. And I cannot install the current patch for marshmallow because it is an unsigned zip.
Where do I go from here reflash the recovery? And install SU again

Flash twrp, then flash the latest supersu from twrp.

will this wipe my device?

No, it should not wipe the device.
If there is data on your phone that needs to be saved, you could try flashing TWRP, boot to TWRP, mount the data partition, and copy the required data to a computer. Once copied, flash supersu and try to boot.

[Q] Can you root the HTC Wildfire S without custom recovery such as CWM?

Basically I followed a guide on here before to root my phone with the simple procedure:-
1. Unlock bootloader at HTCDev
2. Install clockwork mod via fastboot recovery custom_recovery.img
3. Install zip from SD card using CWM (root.zip - includes all root items)
4. Update Superuser via PlayStore
These are the steps I followed when I first rooted my phone, however after a while my link2d and something else was causing my apps to crash, and eventually link2sd kept asking for root permission, and superuser would freeze. For about 7 hours last night I spend trying to fix my phone, which I did by doing a factory reset, then restored my stock ROM using CWM, then loading up a stock recovery.img file which I found on here somewhere, and then eventually I got my phone back to normal. By the way when you go through the bootloader and select recovery, when I get onto it, it justs sits there with a disk icon and a red 'X' or something, is this normal? However, want really p***ed me off was that I thought restoring a backup using CWM also restores the recovery and completely removes the CWM. My question is, instead of me going through all this hassle, is there a way I can FULLY backup my phone and then attempt a root without CWM or any other custom recovery? I have already tried the HTC super tool v3, superoneclickroot and another quick root that was advertised on here, and neither of them work.
My outcome would be to simply have root privileges on the stock ROM on my HTC Wildfire S (S-ON) 2.26.401.3, and if and have a full backup of the phone as though it was new (no root, no CWM etc.) and if a problem occurs I can simply restore everything.

[Q] Botched TWRP upgrade, now lost root access

While attempting to switch to CM11 I tried upgrading TWRP from 2.4.4 to the newest 2.6+ and it messed up my recovery. Then, while trying to re-flash an older TWRP, I accidentally installed SuperSU over an existing install, and lost root. Tried re-rooting the device using motochopper and it gets to the last part, "rooting device" and it says "failed". Device the reboots, I try to open SuperSU and it says "no SU binary installed". All I'm trying to do is put back TWRP 4.2.2 so I can restore my device. Please help
EDIT: Tried using fastboot to install image, everything looks good, then my tablet freezes up. I do a power cycle, it reboots, and the recovery didn't flash.
UPDATE: Recovery flashed and wiped EVERYTHING. I am back on recovery 4.2.2.0 but nothing is mounted and I can't mount anything, I can't make backups or restore images, and ADB Sideload does not work. Any help would be really, really awesome. I have SDK Manager, and I can currently use ADB on my computer, I just don't know what commands, blobs, or images to use.

Can you use fastboot to reflash the stock ROM?

[Q] Can't install TWRP recovery

Can anyone tell me how I flash a recovery to the device from a zip file? Going into CWM and flashing the TWRP recovery initially seems to work, but if I then interrupt the reboot and go straight into recovery, I still see CWM, not TWRP. I'm stuck on the CWM recovery and need TWRP to try to install the Kitkat upgrade.
Should I unzip the components first and then flash the image using fastboot, or is there another way? I'm wary of fastboot as I've already (temporarily) "bricked" the Xoom by flashing a zip instead of an image that way. None of the instructions I've read has much advice on getting round installation problems.
I'm guessing the persistent CWM was caused by my selecting (at an earlier stage) the CWM option to fix the problem of the stock recovery being reinstated at each reboot. Can this be undone? Although I've installed Xoom-Universal-Root, apps that require root access - including GooManager - also fail with an access error. It's hard to tell whether the device is now rooted or not, so if there's any method of getting further without root access, that would be great.
====================
Edit: it looks as if the instructions I saw online, which mentioned two separate TWRP recoveries, were incorrect. To get Android Kitkat 4.4 onto my Xoom I didn't need the initial TWRP recovery, only the BigPart version. Once I skipped to the BigPart recovery, the problem described above did not recur.

TWRP installation after having rooted

Hey guys,
Recently moving back to Android with a Samsung Galaxy S7 (SM-G930F) and I have some problems to get everything working. I didn't find (or didn't managed to find) the informations I was looking for on the forum or anywhere else on internet.
Here is what I did since now:
1. Rooted my phone with CF-Auto-Root.
2. Phone rooted correctly, SuperSU installed => no problem
3. Installed TWRP Manager.
4. Launched installation of TWRP from the TWRP Manager and selected the latest version of herolte (3.0.2-2).
5. Installation failed, relaunched it, didn't get any notice of success or failed this time so I presumed it was good.
6. Restarted the phone in normal mode => No problem.
7. Restarted the phone in recovery mode => Access to TWRP asking me if I want to stay in read only or allow read/write.
> Can I boot up at this stage in read/write without causing any issues since I saw in the TWRP root installation process (http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770)
"By swiping right, you will trigger dm-verity, and if you don't follow step 11 you will be unable to boot!
If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications."
> Since I am already rooted, it shouldn't cause any issues right?
8. I tried to do a backup of my phone but the data folder is showing no data and when performing a backup I am getting a "failed to mount /data error"
> Don't really know how to fix this error.
> I can backup without any issue Boot and System.
Thank you per advance for your answers
1. You need to flash dm-verity and force encryption disabler before you swipe right and activate read/write. Otherwise it won't boot.
2. If you want to do a backup with TWRP you need to format data once, so the encryption is disabled. Just perform a backup via Titanium and format data in TWRP. Afterwards you can make backups in TWRP.
Thank You.
I just did the steps described but it seems that I lost my root after having wipe the data partition.
Now when I am rebooting the phone I am getting "kernel is not seandroid enforcing" in red on top of the screen but the phone still boot up fully.
Tried to reboot in recovery but it seems that TWRP is not present anymore.
I re-rooted the phone using CF-Auto-Root.
Now the phone is rooted, I installed once again TWRP Manager and tried to reboot in recovery mode but getting "dm-verity verification failed…"
I don't have the "kernel is not seandroid enforcing" error anymore.
Do I need to reinstall TWRP in order to solve the issue?

Hi
did you do this?
Point 11
If you want to be rooted with SuperSU:
Download the latest SuperSU by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer no-verity-opt-encrypt.zip to your device over MTP* and flash it using [Install] in TWRP.
Kernel thing is normal ........

Thank you for your reply.
Since the phone was already rooted I didn't done the SuperSU but wipped the data partition and flashed with the "dm-verity and force encryption disabler".
After reboot I was not rooted anymore, so I re-rooted the phone and reinstalled the aps.
Now if I try to reboot in recovery mode, I get the error "dm-verity verification failed…"
If I try to factory default the phone I am getting the same error.
Do you think I can just flash back in stock firmware using odin and the good version downloaded from sammobile? It will remove TWRP and the root right ?

Hi
Flash a stock firmware is an option but not necessary at this point
Go back to TWRP page
http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770
and re do all this steps one by one ( 1 to 13 ), make sure OEM unlock is enables , back up important thing before you do anything just in case
FULL STEPS FOR OBTAINING ROOT
You can follow this video by Max Lee if you'd like: How to Root Galaxy S7 & S7 Edge! [Exynos ONLY]
Otherwise, follow these instructions:
In your ROM, go to Settings -> About device. Tap 7 times on Build number to enable Developer options.
Now go to Settings -> Developer options. (above About device)
You need to enable OEM unlock, otherwise you might end up with boot problems or be unable to flash later on.
Extract Odin_3.10.7.zip to your computer.
Install Samsung Mobile Phone Drivers for Odin to find your device.
Download a .tar image of TWRP for herolte.
Reboot your device into Download mode. To do this, select reboot from the power menu and hold the [Volume Down] + [Home] buttons while your device reboots.
Once you reach the Download mode warning screen, press [Volume Up] to continue.
Open Odin and place that TWRP tar file in the [AP] slot without touching any other options, then press [Start].
Hold [Volume Up] + [Home] buttons near the end of the flash, and keep holding them until you are in recovery.
At this point, you will reach the screen asking you if you want to allow system modifications.
By swiping right, you will trigger dm-verity, and if you don't follow step 11 you will be unable to boot!
If you are going to root your device and follow the rest of these steps, then it is safe to swipe right and enable modifications.
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
If you want to be rooted with SuperSU:
Download the latest SuperSU by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer no-verity-opt-encrypt.zip to your device over MTP* and flash it using [Install] in TWRP.
Go to [Reboot] -> [System].
Wait 5-15 minutes for your device to finish setting itself up.
try this first....

How to flash this file? Please treat me like an idiot. What exactly do I have to do?
I am trying to flash the ROM of a different model of my phone, and thus need TWRP, but this needs to be unlocked first somehow.

Stuck on bootloop TWRP without decryption, help.

Hey guys, so i had weird problem (status bar not visible after unlocking device) when updating my phone to 9.5.8. so i decided to flash the rom again to see if the issue goes away. I am rooted and unlocked and everything was working fine (apart from the status bar). I tried this method:
1. Downloaded the 9.5.8 update from Oxygen Updater (DONT REBOOT)
2. Went to Settings\System\System Update and click on the wheel on upper right corner.
3. Select Local Upgrade, then install the update (DONT REBOOT)
*DO NOT REBOOT after applying the update.
4. Launch Magisk, and click the first "install"
5. Choose the "Install to inactive slot (OTA)" option
6. Reboot once completed
On step 6 it failed, i rebooted directly into the Oneplus recovery and not TWRP. So i tried fastboot boot twrp.img and flash the installer. After that i rebooted the device and now it goes directly into twrp but without decryption, it wont ask for my PIN and i get the screen "Unmodified System Partition. Keep System Read only? Installing zips or performing adb operations may still modify the system partition." On the bottom i can "swipe to allow modifications", which i swipe to allow but i can't access any files on my phone, and that is my dead end. Help would be much appreciated.
I also tried flashing Magisk and also Magisk Uninstaller (uninmod wasn't found).
Also tried command "twrp decrypt password" in the Terminal and got "Failed to decrypt data"

So to be clear: right now, you have access to twrp but not the data partition (twrp does not prompt you to decrypt), and when you reboot to system from, you are bounced back to twrp. Right?

Yes, but i got frustrated and as i had done a Titanium Backup i just wiped everything on stock recovery and flashed the latest rom with twrp. Is there a clear instruction on how to update the rom when rooted? I just don't want it to happen again.

Don't mess with stock recovery if you already have TWRP and Magisk aboard.
Here's how to update to 9.5.9 (or whatever) when it arrives:
- download your 3 zips: the latest full ota ROM, the latest Magisk, and the latest TWRP installer.
- boot to TWRP recovery
flash the ROM and TWRP installer
- reboot to TWRP recovery
flash Magisk
wipe dalvik
- reboot to system
There's a possibility after these steps and you're happily on the ROM, you might find that you're not rooted (it's more likely on a custom ROM than OOS). In which case you just reboot to recovery and flash Magisk, and then reboot to system. Done.
Discussion:
If you want a clean flash, you'd simply do a TWRP factory reset (standard wipe) instead of wiping dalvik.
Consider flashing both slots (A and B) whenever you update OOS, for two reasons. First, you don't have to keep track of which slot has which version of OOS should you flash a custom ROM or kernel with a specific version of OOS required as a base. The second reason is more compelling: the way the data partition changes encryption every update has obviated the reason for A/B slots, in that if newly updated B changes data encryption upon boot and then something happens, you cannot revert to A because A can't read the new data encryption. So the solution is to update both A and B at the same time so both slots use the same encryption and can both access the data partition.
Or like me, run the device decrypted (i. e. without forced encryption).
Good luck
