[Q] Preserve Root Through Factory Reset

Hey does anyone know if OTA rootkeeper can preserve root through a facory reset? I want to downgrade to .30, root, upgrade to JB, then factory reset. I know it will preserve through OTA, but i want to know if it is possible to preserve root through full reset, with OTA rootkeeper or any other methods.

Yes, it should keep root after you did a factory reset. Make sure you download and installed superSU, once download open up superuser and and superSU. In supersu put a check for preserve root in settings(if you have the paid version), if you don't open up superuser and put a check to preserve root. Then Open up OTA root keeper, make sure you save root by click "Temp unroot". Now turn off your device and boot into "wipe data" execute it. Once your device boot up, re download superuser, open it, then download and install OTA root keeper, open up then click restore. You should have root back.

Have you tried? Did it work?

I have tried this 3 times while I'm on JB, then one more time with factory reset 3 times consecutively and I still able to preserve root. Then again, still there are some odds out there, nothing is 100% with tf700.

I don't see anywhere in SuperSU to check preserve root. Am I missing something?

You need a paid version to have the option. It's gray out on the free version.

Hey all,
been trying to get help on this in other threads as well but not som much luck.
1- From ICS 9.4.5.30 I rooted using DebugFS, which installed superuser
2- Then installed RootKeeper, click on Protect Root, then click on Temp Un-Root
3- Upgraded to JB 10.4.4.16 through SD card
4- Open RootKeeper but no Restore button is there.
I have unlocked bootloaders and no wipe data anywhere in this process.
Will installing SuperSU before upgrading to JB change anything at all? What am I doing wrong?

After you rooted, make sure you open superuser, then dowload superSU, open the app also, then download the OTA root keeper then click protect root,(all the boxes should have a check), click on Temp Un-Rood, now do the upgrade.(you must update through OTA or use incremental dlpkgfile to update, a full package will wipe everything).

Since you already unlock it's a shame that you're not runing custom rom. If you already on JB, you can do it this way, download Android sdk to your computer and install it. During the install process, you need to pick the package to install, pick 2 packages that named with android. The sDK is installed in this directory on your computer,c:\android-sdk\platform-tools, in this directory theire is a command called fastboot.exe. Download recovery image file from here http://www.mediafire.com/?ju5p2p9adpuus2k and put this file "recovery.img" to the same folder as fastboot.exe (c:\android-sdk\platform-tools), Now let begin:
1. connect your device to your PC with usb cable
2. boot your device into fastboot mode (select the USB icon)
3. On your pc open cmd (command prompt) and navigate to this directory; c:\android-sdk\platform-tools
4 type :
fastboot -i 0x0B05 flash recovery recovery.img
once done type
fastboot -i 0x0B05 reboot
That's it. You should install sdk because it's a very useful tool, and since you already unlocked, it such as waist if you not runing custom rom. You are going to fall back in love with your device when you're running custom rom. Go for it bro.

With superuser do not have this option (check preserve root) but after the OTA update I was able to restore the root.
Do you even restoring to factory data I am able to replace the root with Rootkeeper?

I'm not sure what you did that's different from me, but I used Voodoo Rootkeeper and worked fine. I don't have SuperSU installed.
I'm thinking you didn't save your root properly when you went to protect root.

SuperSU is the latest and all developers are going to use this app going forward. SuperSU is more reliable. Superuser is old and will slowly phase out.

So if I understand, this will install a "custom" recovery mode from which i can flash CleanRom?
You're right about falling back in love with it. I own a Galaxy S and an S3, and I don't know if there's any device easier to modify then the Galaxy series. They're awesome and so much fun.

How to manually unroot

I recently upgraded to android 4.42 and it's honestly worse since I cant use MX player or some other apps, but I also lost my root. How would I manually unroot? I rooted used ChainFire and currently cant get into the app to unroot.

Are you looking to unroot? or to re-root?
If you want to re-root, you just need to flash the SuperSU in recovery.

Sorry, I didn't flash any custom ROMS at all with my nexus or any other android phone, so I'm completely blank on this subject.

When you had rooted originally, how did you root? (are you sure you were rooted? If not, you will need to check whether your bootloader is unlocked. If you were rooted, your bootloader should be unlocked - unless you relocked the bootloader after rooting for some reason)
Did you flash a custom recovery like TWRP or CWM? If so, you should be able to copy the SuperSU file to your phone (any where), and reboot into custom recovery (hold down power and volume down when phone is off, and select recovery option) - once there, just select the option to install SuperSU.
If you don't have custom recovery, you will need to flash that first using ADB sideload - this link has more details about how to install custom recovery and root. (again, assuming you have an unlocked bootloader. If not, you will need to unlock bootloader, which will wipe your phone - all data will be wiped out)
Read the first post in the link I provided - carefully

[Q] Can you OTA update a Nexus 5 and keep root?

Ok so I just recently got my hands on a Nexus 5 which I rooted with CF Auto Root and relocked the bootloader with Bootunlocker for security (I'm guessing I should unlock before the update). I see reports surfacing of a possible 4.4.3 update in the near future. So before that happens I want to figure out the best practice for updating a N5 with CF Auto Root. It stands to reason I'll do a full backup so that's a given.
I'm not new to rooting. Done it a few times. Just haven't had a device that gets regular OTAs in my country so it hasn't come up.
Is there a way to update so that root is preserved? Obviously I'd like to keep the process as simple as possible but if I have to work from scratch it's not the end of the world.
As I understand it, you can do normal OTA as long as it's stock but you lose root. In that case, does the OTA relock the bootloader or will it stay unlocked? Which then basically means a new root which wipes the device.
Or perhaps it's better to ask what the best procedure for updating a stock Nexus 5 with CF Auto Root.

Everything that you have ever wanted to know about OTA can be found here http://forum.xda-developers.com/google-nexus-5/general/info-nexus-5-ota-help-desk-t2523217

Ah thanks. Appreciate it.

generally no, after ota you lose root. but there are apps that will save your root so that you keep root after an update.

I've been looking at Survival Mode in Super SU and RootKeeper but there seems to be some question as to their success.

ive never used any since i dont ota, i update my custom rom as soon as its updated, but ive heard of success with rootkeeper. but it doesnt matter, it literally takes 3 minutes to root a nexus the right way(via fastboot).

Yea, I should use fastboot in future.

The stock Android OS update will not relock the bootloader. So, once you apply the OTA.zip file in recovery, all you will need to do is reflash the SuperSU, and you are done.
(Note that depending on your system status, you may not be able to apply the OTA.zip directly - for instance, if you have updated/deleted system files etc, in which case, you will first need to go back to stock - refer to the link that @mistahseller provided for details about how to go back to stock)

Good point. I assumed that op had installed a custom recovery when he rooted, but that is not always the case.

Ok so I'm going to sideload myself. Been a while so I just want to confirm the process so I don't screw up.
I'm using TWRP
Obviously I'll do a NANdroid and probably Titanium as well.
1) Unlock bootloader with Bootunlocker
2) Connect device to PC
3) Boot into TWRP recovery and go to Advanced > ADB Sideload
4) type adb sideload update.zip (or whatever I call the file)
5) reboot device and check if it's working
6) reboot to recovery and reflash superuser.zip
I think that's it. Is there anything else I need to be aware of? If I'm right it should then be updated, rooted and in the same state before I updated.

I am in the same situation. I am currently rooted with a unlocked boot loader. When 4.4.3 comes along I plan to upgrade it. I have only rooted and have CWM no custom ROM. I know o cannot perform a OTA update. So do I copy the update zip (4.4.3) and just flash in CWM? Is this correct, and if so do I lose root/ boot loader. Thanks. I have read the thread above but do not understand

Flash stock system.img and flash recovery.img and then do the update.zip from the stock recovery..
If you don't want to flash, then make sure you have removed all the modifications you have done to system apps. If you don't remember then I would certainly recommend flashing stock images...

[Q] 4.4.3 Update

Hello everybody.
First of all, I'm not sure whether this is the place to post this kind of questions. My apologies in advance. Here is my problem.
I rooted my nexus 5 nearly after a month of having bought it using the nexus root toolkit. Today I received the 4.4.3 OTA, and somewhere I read that it would fail most likely. I also read read that I should set survival mode in SuperSU (a pro option) in order to retain root access, which I couldn't. I tried to update via the OTA thinking it would fail, and it worked, only that I lost my root access.
Is there an easy way to regain root access? I don't want to wipe and re-install everything. There are only a few apps I use that need root access, however it would be nice to have them back, nevertheless.
Thanks in advance.
PS: Now I am able to record video hassle-free, no more static noise in the background :victory:

Thanks for your reply. I have already SuperSU on my phone, but when I press it it says there are some binaries missing. Busybox doesn't update the binaries since it has no root access and says the device might be improperly rooted. My recovery is TWRP, so I can actully flash root files or such.
Edit: I just tried to boot into recovery and it didn't work quite well. There is a fallen android guy with a red triangle. So I don't have recovery either it seems.

6.0.1 ota with stock rooted 6.0

My v10 downloaded an OTA , which im assuming is 6.0
1. Im rooted on stock 6.0 and unlocked boot loader. Will the OTA work without messing up anything ? Ill have to root again im sure, just want some info before i pull the trigger.

I don't think the update will even proceed being that you're on a rooted ROM. I have that notification too, and i just don't know how to turn it off.

I to am rooted,unlockboot and stock rom. I don't feel like taking a chance. So I used titanium backup to freeze the software update and in the drop down notification if you press it, it's a notification from Google play services if you block it in apps it will disappear from your drop down. I also deleted the update zip in the cache folder.I used es file explorer ,device/cache/update

Okay, I'm assuming you are on H90120e (system version). There is a root exploit for the H90120j update. You just do the following:
Make a backup of your apps and settings
Flash your phone to the new update (H90120j)?
Take a look at either one of these threads to root your device again:

You can't flash the phone that is already rooted and has TWRP.
I am in this same situation. On stock rom with root and twrp. I want to update to the new update, but do not want to loose all my apps, settings, etc.
Question is, how to do the initial update before having to re-root again?
How do we flash the phone with the new update?

Why can't you flash the phone that is already rooted and has TWRP?
All you are doing is opening the LGUP tool and flashing the new H90120j .kdz file using the "refurbish" option then flashing the H90120j .tot file that has TWRP using the "update" option which will flash the phone regardless of what is running on your phone. The guides on the first link explain that. I believe your concern is keeping all of your settings and apps. Look up Titanium backup, it works for me.

Thank you. I only flash the LGH901AT-01-V20j-310-260-JUL-12-2016-ARB02+0ROOTTWRP tot file and all is good.
Well except that I lost Dolby audio.
I will look for a fix.

There's a guide in general that tells how to do all this. In fact jun19inf WROTE it.
In a nutshell, do a twrp backup.
Upgrade to 20j by flashing the stock 20j kbz.
Enable usb debugging and oem unlock
flash tot that has twrp in it.
Now you can go into twrp and 1) root via supersu 2) restore ONLY data from your twrp backup taken previously to get your apps etc back. Alternatively Titanium Backup will also do just fine.

If all is you have is root, you should be able to unroot in the SuperSU settings, and then let the update install. But if you have TWRP, then I can't see any way to do the update without using a PC to flash your phone back to stock ROM and recovery. Although you may check the dev. section to see if Eliminator has a flashable ROM to bring you up to date.

Hi all. I just got my factory warranty back and I attempted to root it. Everything went as it should, until just after the install finished. Instead of rebooting normally, it now will only reboot into TWRP. Once there, when I try to flash a custom ROM (in this case, Bliss, but I don't think it matters, I get an error message that says the zip file is corrupt. Then, while still in recovery, when I tried to wipe everything except the sd card, it says mkfs.fat process ended with error. I then powered down and attempted the factory reset. I scrolled down on both screens and it did not say anything about any errors, so I assumed it took. However, it reboots right back into TWRP recovery. It also boots right to TWRP recovery when I try to boot normally. Of course, adb does not recognize the phone in any mode that I can get into (fastboot/recovery/download), so, I can't use LG Bridge to reflash the original firmware. Does anybody have any ideas for a fix? I know that this replacement phone had 6.0 on it. I thought I did everything to a t? TIA...
OK, not sure how I got there, but when I attempt to reboot from TWRP it says No OS Installed! Are you sure you want to reboot? That at least says what the problem is. Does anybody know how to fix this?

Where can I download the update file?

How to root V10 T-mobile M.M ver V20L
Can some one guide me on the following:
1. Can I flash back and downgrade to Software version V20J from V20L.
2. Is there any root method for V10 t-mobile MM ver V20L.

1. It is well explained in this forum, you CANNOT go back without facing a software brick.
2. You can root your phone through Dirty_Cow method or by flash Eliminater74 ROM (Part1 & Part2).
Again, search for that in this section and in development one...
