Rooting Nexus S [Help]

A while back, I always rooted and unrooted my Nexus S with no problems at all. Now whenever I try to root it, it just goes wrong. I've tried TWRP & CWM, CWM used to always work but now it just messes up. Both TWRP and CWM both give me an error that say Installation Aborted when I try to install a custom rom. I've redownloaded the rom from different browsers and even different PCs but nothing working, still that same error. Does anyone have a guide that is 100% to work without any errors during the process?

What guide are you using?

I used this one: http://nexusshacks.com/nexus-s-root/how-to-root-nexus-s-or-nexus-s-4g-on-ics-or-gingerbread/

1. Make sure you're running one the more recent versions of the custom recovery. You probably are but there are issues with older versions so just make sure.
2. Boot into what ever recovery you pick and do a full wipe. That is everything gets wiped but your SD card. Factory reset. Format /system etc.
3. Flash your ROM and gapps if they are seperate.
You should not get any errors. If your recovery is current and your flashing a new rom onto a fully wiped system and you still get a error either you're screwing something up or you may have a hardware problem.
To rule out a hw problem flash the factory images with fastboot. If those flash normally and everything works it is almost certainly user error.

Alright, thanks Do you recommend that I root my Nexus S or should I wait for the Jelly Bean update? I've rooted before and I enjoyed it but now I don't see that many reasons to root, do you have any good reasons?

I have many. My reasons for root don't matter. If you don't have a reason for root then don't root. Its that simple really.
Make sure you're on a stock 4.0.4 rom. When the ota is out install it.
If you want just root on either os at any time just flash su.zip from custom recovery. Its that simple. Having root on a stock rom does not affect the ota process.

What are your reasons for root? Please share?

Getting rid of stuff I don't want in a ROM.
Apps that do things that require root.Titanium backup/autoruns adaway ( ad blocker app alone could be its one point) etc
Changing kernel settings. Bid/bin clocks volts etc.
Being able to have a replacement launcher use the ICS style widget drawer.
Lastly , I simply just can't see having a computer that I don't have root/admin rights to. Its my damn device and I do what I want.

Oh cool. There is this project that some members from XDA are working on called Sense4All and they are porting Sense to many devices. Im probably going to wait until a fully functionable release is available for the Nexus S. I do like AOKP a lot, so that might be a reason for why I'll root.

You seem to be a little confused with some terms. Root is simply being able to grant superuser permission.
You don't need to root to flash a custom rom on a nexus. Just a unblocked bootloader. You could run aokp or any other rom without root if you wanted to.

Oh, I never knew that, haha. Is it possible to flash a custom kernel with an unlocked bootloader or does that require root access?

m1l4droid said:
No you just need a custom recovery. But using that kernel's mods, like BLN, OC, UV, touchwake, etc, requires apps that need root, like NSTools, SetCPU, etc.

Oh alright. Now I really wanna root + install a custom rom. Do any of you have a full 100% fully working guide for rooting Nexus S and which rom should I flash first? I already know what kernel I want.

Root is gone after flashing stock kernel

I need help, I can't get root access back after flashing stock kernel...
Actually the first time that phone boots I got root but is gone after reboot
I already tried re-flashing SuperSU lastest version, but nothing works...
Any idea?
Maybe need a full wipe, but I dont want to lose all my apps data/savegames, and I can't back up anything cause titanium back up needs root

Hello,
i can help you:
1. Install Supersu from play Store
2. Launch it and install binaries via normal way.
This should work.
TheCrazyLex

Don't install from the playstore, eventually it gives binary errors and that is if it can install binaries the normal way.
That said, download this ( https://www.androidfilehost.com/?fid=23578570567719420 ) and flash it through recovery as if it was a rom.
You're done.

[HELP] Root motorola XT925 with 4.4.2 OTA update

Hello it's been several days i can't find a solution to my problem. I flash official RTFR 4.1.2 via RDS Lite and then i upgrade to Kitkat 4.4.2 via OTA update.
When my phone reboot i have The Unlocked Bootloader Warning logo on the screen, but i lost the root.
This is the version i have: 180.46.127.XT925.CEE-Retail.en.EU.
I did install a recovery (Philz Touch, CWM,) but when i reboot to recovery it was not working and i had the google Droid with a red triangle.
I'd like to know if it is possible to root my phone in order to flash the CM12 ROM? Or with this official update i'm stuck with 4.4.2 and won't be able to root?
Thanks for your help.

When you install a custom recovery after taking the OTA, the recovery will usually ask you to disable stock recovery restore. If you don't, then the stock recovery will be reinstated upon next boot. Once you've got a custom recovery installed and disabled the stock recovery, you should be able to root it from there. Most modern recoveries will handle both the disabling of stock recovery restoration and install root (su) for you.
I know the one I use does.

When i installed the recovery it didn't ask me to disable stock recovery restore. Where do i get that request, on my phone or on my PC? Which custom recovery that allow me to disable the stock recovery do you recommand?

After you install recovery, immediately power off your phone, boot straight back into recovery (not the OS, otherwise stock recovery will over ride the aftermarket recovery), once in recovery the update script will complete and the installation will be complete. Once in the recovery, you can choose the option that CW mentioned.

[HELP]can't reroot or flash stock recovory

so, when i rooted my N5 i wanted to see if i could use super user and not supersu, so i uninstalled it. but not how you think. i went into the supersu app and uninstalled it to add a new superuser app. i downloaded super user but it didn't work. so then i posted a thread on here asking what happened and i had the response that i need to reflash root. after watching so many videos on how to do it my N5 stays stuck in downloading and doesn't do anything. i still have an unlocked bootloader but i cant flash supersu. i assume i need to be rooted to reflash stock recovory...

To flash root, you flash the root zip from you custom recovery.

You need to have a custom recovery installed to flash SuperSu.
Everything you need can be found here:

oh, i thought i needed to be rooted or have supersu to even use a custom recovery. (in my case TWRP)

Nope. Just for those silly "companion" apps like "TWRP manager" need root. But you don't need those. Boot into recovery manually to use it.

Uninstalling TWRP to default recovery?

I need some root functions temporarily then would like to go back to stock without doing a full wipe. I know I can remove magisk and root but I would like TWRP removed as well because it may cause issues with future app updates that I use.
Is there a way to uninstall TWRP or install the default recovery over TWRP?
Thanks.

Not clear whether you actually installed TWRP and rooted yet, or not. But if not, you don't actually need to install TWRP to root the phone. There are 2 main root methods, neither of which requires TWRP to be installed:
1) Flash patched boot.img to root. This method doesn't touch recovery.
2) TWRP method. For this method, you need to fastboot boot TWRP.img, which is just a temporary "remote" boot of the TWRP image that resides on your computer. TWRP is not actually flashed to the phone when you do this. Installing TWRP to the phone involves (after booting TWRP as mentioned) then flashing the TWRP installer zip, which is purely optional. You can actually skip that step, and just (while booted TWRP) flash the Magisk zip to obtain root. if you do it that way, you have root (with Magisk) but not TWRP (still stock recovery).
In either case, you can use the fastboot stock ROMs to return the boot.img partition to stock using the fastboot stock ROM (as the previous reply also suggested):
https://forum.xda-developers.com/oneplus-7-pro/how-to/rom-stock-fastboot-roms-oneplus-7-pro-t3931424
Be aware, that you can't just flash a stock recovery (by itself) on this device. For A/B partition devices like the 7 Pro, there is no discrete recovery partition. Recovery is a part of the boot.img partition. You therefore need to flash the stock boot.img partition to get back to stock recovery (this should also unroot the phone).

Keep the stock boot image around along with the image that has TWRP and Magisk.
You can swap back and forth just by flashing the boot image.

Thanks for the reply.

In method 2) Does this mean it only temporarily installs twrp. Does this mean after boot TWRP is actually gone and if I boot anytime into recovery or "adb boot recovery" then it will bring me back to the original recovery of oneplus?
For example say I install TWRP via method 2, install magisk and root. Do all my root things I want, uninstall root and magisk, and reboot that means everything is as if I didn't install a recovery or root?

Do I have to pull my stock recovery image or use one of the ones linked?
I have a T-Mobile which I unlocked the bootloader and installed an international firmware. I would like to return to this and not the original T-Mobile firmware.
Thanks again.

Probably better not to think of if as "temporary" installing TWRP. You either install it, or you don't.
If you only do fastboot boot TWRP, and flash Magisk, you haven't installed TWRP at all. It remotely boots/runs the TWRP image that is located on your computer. Nothing is installed TWRP-wise (temporary or not) to the phone when you run this command.
So if you fastboot boot TWRP, and flash Magisk, you will be rooted, but still be on stock recovery.

Be careful when you say "uninstall root and Magisk" since that doesn't specify how you intend to do that. If you mean flashing the stock boot.img, you will remove root and revert to stock recovery. So it is somewhat irrelevant whether you installed TWRP or not.
You will probably also need to delete the Magisk Manager app (to remove all traces of root), as this resides on the data partition, and won't be affected by flashing back to the stock boot.img partition. Keep in mind that this is just an app for managing Magisk. Deleting this does not in itself unroot the phone (some folks get this confused).

To remove root (and TWRP is applicable), you want to flash the boot.img which corresponds to whatever stock ROM when you rooted it. So in your case, the international (unbranded) boot.img, which you can get in the link I posted previously.

By uninstalling I meant uninstalling the app and flashing the uninstall Magisk zip. I was thinking when I do everything I want then fastboot boot TWRP, then flash the Magisk uninstall zip.
Would this work or do I have to flash the boot.img no matter what? or can I also restore the boot section which I will initially backup in TWRP?

That should work. Can't say from experience. I've never uninstalled Magisk personally!
Not to say that whatever changes you made under root will remain. That is a whole different thing, that I can't answer.

Should have the same result as flashing stock boot.img.
