i was looking and serching for a fix my nexus s , i update from Alpha 13 to ICS 4.0.3 and i lost ither root or SU permicion can someone guime to right way i nedd get to CWM and go to my backups and i can do the rest i try update SU buth i not able to get CWM i just get stock recovery i try update SU from app not root acdsse .
I would think that you need to flash your recovery again. fastboot your recovery .img then flash rom manager after you reboot and you should be ok. do this the same way you did when you originally rooted your phone.
You may need to unlock bootloader, root and install. Official stock ROM erased them all.

hello , my iconia just updated to ics(ota update). i root my a500 with ics root tool. after that i tried to install the supersu but i get installation failed error. After that i tried the superuser and i saw that i have the 3.0.3.2 version but i cant update. im getting this error : remounting /system as rw fail. any ideas?
My second question has to do about boot loader etc. im confused with all that information..
After the update acording to Acer recovery installer i have 0.03.12 ics version( before update i had 3.1 and cmw recovery installed) . to be able to flash a custom rom i have to change the bootloader with afterota tool? and then just install a the cmw recovery from acer recovery installer?
thanks

First question. Having root and system rw is not exactly the same, especially with the ICS Iconia tablets. You can use a file manager, like ES Explorer or RootExplorer and try changing the /system to rw.
If you can't get /system rw with the tool you used, try Zero-Nulls rooting tool.
http://forum.xda-developers.com/showthread.php?t=1546593
Next question. Bootloader. If you want to install custom ICS roms, it's advisable to install the Unlocked bootloader and CWM. Reason is, ICS and the stock bootloader, is really a pain when trying to get /system rw. The unlocked bootloader and a custom rom/kernel have the security features taken out, so all you need is SU and don't need anything to get /system rw.
Not to mention the unlocked bootloader has fastboot, and, you can change your boot images.
Some people keep the stock rom, and just change to the modified kernel via CWM for the easy /system rw
Regardless, pay attention to the instructions, and keep in mind, if you are on stock ICS, you have to delete the boot-recovery.p file from /system, or else when you boot to the OS, it will overwrite your CWM.

Yeah, gotta set permissions. Remember to delete that boot-recovery.p file. Before you start doing things. Otherwise, your CWM you install, will get overwritten 1st time you boot into your stock OS.
Write down your UID number, always.

For some reason I seem to have lost root. I think this may have occured when I updated to 4.2.2, it automatically asked to update OTA. That or this occured from updating SuperSU.
When I try to go into recovery mode I see a android laying down with an exclamation point on his belly. I can't get into TWRP recovery.
SuperSU gives the error "There is no SU binary installed and SuperSU cannot install it"
I tried opening up titanium backup, and it says I have no root.
The fastboot states me phone is unlocked.
I have no issues rerooting, but I'm wondering:
a) Why and how this happened? Was it from the OTA update?
b) How I can prevent this in the future
c) Can I still back things up before rooting?
d) Will I lose everything when trying to root again?

Just reflash the superSU.zip from here http://download.chainfire.eu/315/SuperSU/UPDATE-SuperSU-v1.25.zip in CWM and you should be rooted again. You will not loose any data so no need to backup. Download OTA Rootkeeper from Play to regain root after installing future OTA`s.
I'm not using CWM, I'm using TWRP and I can't seem to boot into it.

Try cmd and type: adb reboot recovery. If you see the androidian (stock recovery) you have to reflash the TWRP img file in fastboot mode.
Will this reset my phone? Or does only rooting do that?
You will not loose any data.

Let me guess, you used a toolkit to root?
a) You did the full OTA, so you lost your custom recovery.
b) flash images through fastboot and skip the recovery.
c) Only after you flash a custom recovery. If your recovery is sitting in the same folder as fastboot and named "recovery.img, simply cd into the fastboot folder in a command prompt and type
fastboot flash recovery recovery.img
d) Not unless you lock or relock your bootloader.
OP, you need to do some more research and uninstall the toolkit from your computer. You know just enough to cause yourself problems, but not enough to know why they happen or how to fix them.
Yes the OTA update got rid of the files or partition that is created in order for you to have root access. Your custom recovery was also replaced with the stock recovery (android lieing on its back with red triangle).
To prevent you being unrooted in updates you can try using OTA RootKeeper available on Google play but this is not guaranteed to work.
You can use carbon to back up your data as this does not require root access to work.
And no you will not lose your data if you re root again, this is only done when you unlock the bootloader.

Thanks all, was able to get it fixed by re-rooting!
Hi,
I lost root after updating to JWR66Y, and when I open up SuperSU, it says "There is no SU binary installed, and SuperSU cannot install it. This is a problem!"
So I turned off my phone, pressed volume down+power button to go into TWRP and re-flash SuperSU.zip, but the screen only shows broken android with exclamation mark on it.
So, my question is, what do I do? I want to flash TWRP via adb and then flash SuperSU.zip via TWRP. Is that the correct procedure? I'm afraid if something goes wrong I won't have a way to restore my nandroid backup or something.
Thanks.
you always lose root if you take an ota update or flash the factory img. when you flash stock, its just that, stock. its been that way since the beginings of android.
you want to fastboot(not adb) a custom recovery, then flash the latest su binaries via your custom recovery.

Yes you can apply ota update via twrp recovery. For this just follow following steps(On your own risk) by the way following method worked for me to apply latest 5.8.0.19s update.
1) Download the latest ota update it should be located here (internal storage/data/com.letv.android.ota/files/otaUpdates) folder.
2) There should be a zip file just cut and paste it in root folder for easy process.
3) Now boot to TWRP recovery and flash zip file which is pasted in root folder.
4) Now format dalvik cache and if you want root, then root again because due to flashingnew rom root access and all other changes you have done in system will lost but all your data will be safe... (This method is usefull for same type of rom i.e. from stock rom to stock rom or custom rom to custom rom).
5) Just for your knowledge 5.8.0.19s update file is full rom file but if you want other versions such as 5.8.0.16s then use offline update packages which are full size i.e. around 1.7 gb.
Also you can flash root since twrp comes with inbuild root tools just locate it in twrp recovery in advanced/tools/root.
Also you can install stock rom just after flashing stock rom in place of any custom rom just wipe data and factory reset and then apply root. and reboot normally.
Good morning, I wanted to know if I can upgrade to Android 7.1.2 beta with root and custom recovery installed. Do I have to remove them before upgrading or the upgrade will remove them automatically ? Will my device even boot if I update with root and custom recovery?
Thanks
Nope. Cant with custom recovery..

Your phone will boot loop if you don't go back to stock recovery first. I tried just to see what would happen and that's what happened. People who tried to flash it with Flashify reported no success.

Stock ROM? Important information you omitted. From a guy who always runs the latest stock ROM rooted and custom recovery here's how you do it: You do not have to remove them first, and although they (SU & kernel) will be overwritten with the new boot.img, it is very easy and straightforward. You need the TWRP flashable (beta) OTA zip file, in the OP here. Put the latest SU and your custom kernel on the device root, or wherever. (should already be there) and then reboot to TWRP recovery. Select "Install" and then select the OTA you downloaded above, and tap "Add more zips". Next you want to add the latest SU zip (2.79 SR3) and last add your kernel. Mine is EX. Once you have queued all 3 zips, in less than a minute you will be back up and running 7.1.2 , rooted and with kernel. Even if you flash each file individually you will still be ok. (OTA, SU, Kernel). See the same thread further down... Credit for the TWRP flashable OTA goes to @Displax.
