[How To] Install OTA and root.

I've seen and answered this question quite a few times so I thought I'd just write down the procedure once so everyone can find it.
So you want the latest OTA and want it rooted but you have no idea how to get there? I can help.
Prior to yesterday I was running rooted stock with TWRP recovery. The OTA failed of course.
In order to install it and root I did the following.
1) install rooted stock image via odin (found at http://forum.xda-developers.com/showthread.php?t=1739426) This re-nstalled stock recovery.
2) install and run voodoo ota root keeper from the play store to preserve root.
3) took OTA download and let it install
4) ran voodoo OTA rootkeeper to restore root again
5) Install goo manager from play store
6) install twrp via goo manager
7) made a rooted stock nandroid backup.
The above procedure didn't wipe any of my data or settings because I came from rooted stock to begin with. I just used odin to restore the recovery and missing bloatware..
Hope this helps

Do you have the clockworkmkd recovery file I need to flash through odin? Does this mean I don't have to use adb?

I didn't use ADB. I used twrp for my recovery, but you can install rom manager and cwm recovery with it instead of goo manager and twrp.

I lost my root when i did the update...
can you give step by step on how to root again after the update and install the google universal search?
thanks...

Flashed the rooted stock image via Odin, update failed at 27%. Any ideas?

No idea. Just reporting on what worked for me.

If you've disabled or uninstalled stock at&t and Sammy apps (like Flipboard, clocks, etc.) the update will fail. You need to enable/reinstall stock apps.

Hi, I used Voodoo Root Keeper to regain root. However, in my device status it is now saying modified instead of normal. How can I fix that?

You can't. Don't worry about it.

It looked like reflashing the rooted stock rom did reinstall the bloat I removed.

There's a much easier method to get root back after the update.
Flash CWM/TWRP
Flash the file I attached below.
Install Busybox from market
Reboot
Done deal
It does work. I tested earlier today from G1 stock unrooted. Pulled and installed the update, flashed CWM. Flashed the attached file, busybox download and profit. Then used gooomanager to change to TWRP
Here's the original site I read about this method way back when...

Gunny's method does work, just giving another option

OP guides worked for me. Thanks

Yes, it does work. Get a custom recovery back (CWM) and flash the file I attached in my earlier post. Saves the time from flashing a stock rooted ROM and going from there as a starting point.

[Q] Re-Root After 4.1.2 Upgrade?

I have an unlocked I9250 Galaxy Nexus that was rooted. I recently upgraded to 4.1.2 using the automatic update. I had Voodoo OTA Rootkeeper installed which worked for the last upgrade, so I didn't even think about it. But I lost my root. Is there a way to re-root without losing any settings or data? When I boot into recovery I see the android with a red exclamation point. I assume My custom recovery was removed with the upgrade. Thanks!

I know this isn't answering your question, but I wanted to mention that I, too, had Voodoo OTA RootKeeper installed when I updated to 4.1.2 and it worked perfectly. I was on stock 4.1.1.
Sent from my rooted GSM Galaxy Nexus

Was I supposed to run the rootkeeper app prior to upgrading? I did not do that. Although I would think that it would have saved the superuser file from the previous run. I'm not sure how it works. either way, I definitely am not rooted anymore and not sure what to do. I'm not even sure if there are tools to root 4.1.2, or if the old toolkit works the same with this upgrade.

Hmm good question. All I did was open it prior to the update to verify that all of the checkboxes under "Status" were filled in and su was protected.
After the update downloaded, rebooting took me into ClockworkMod Recovery where I had to give the ok to install the new file.
The only thing I needed to do after updating was flash ClockworkMod Recovery again. Everything else was fine.
As for rooting your new stock 4.1.2, here's a good place to start. You shouldn't loose your data assuming the bootloader is still unlocked.

Thanks everyone. Will doing this require a factory reset or any internal data loss? Or does that only occur when unlocking the phone?

[HOWTO] [ROOT] No Tripping Flash Counter - Root Injected L900VPALJC +[TWRP] + more

This is a root injected FACTORY Stock L900VPALJ1 Odin Flashable Image. You flash this in Odin just as you would the completely stock ROM from samsung. I've simply injected the su binary and SuperSu app so you now have rooted stock image.
So if you want to keep your device stock yet have the functionality of root without tripping the counter or messing up OTA updates then this would be your best bet.
You can get ODIN here
and the drivers for the SPH-L900 so ODIN can detect your phone can be found at Samsung's site. Click on the Manuals & Downloads tab at the bottom and then on Software for the latest driver.
Instructions:
First, Download Image:
New Full Rom VPALJC
Mirror 1: root66_SPR_L900VPALJC.7z
Orig Release JB 4.1.1
Mirror 1: root66_SPR_L900VPALJ1.7z
Mirror 2: root66_SPR_L900VPALJ1.7z
Second, Extract and Flash:
Extract the root66_SPR_L900VPALJ1.tar.md5 from the .7z file you downloaded.
Use Odin, put phone into download mode [with phone off, hold vol. down + home + power ], connect to computer and open Odin.
once in odin click the PDA field and select the root66_SPR_L900VPALJ1.tar.md5 you downloaded.
Leave Auto Reboot and F. Reset Time checked.
click start and
when done let phone reboot.
If you have issues flashing with Odin please ensure you are using the microusb cable that came with the phone, users have had issues using other cables.
If you just want a stock, rooted phone with no custom recovery, no plans to flash custom roms, etc. then you can stop HERE.
OTA Updates:
Stock Recovery: Once rooted with above method, if you receive a notification for an OTA update, it has been verified you can use OTA RootKeeper to retain root through the update process.
Non-Stock Recovery: If you have loaded a non-stock recovery (per below) you can simply use it to flash the OTA update flashable zip I've created.
Mirror 1: OTA Update LJ1 to LJC
Mirror 2: OTA Update LJ1 to LJC
Optional, Recovery (will trip counter):
It seems loading any custom recovery will trip the download mode flash counter. Loading a non stock recovery will also prevent you from successfully applying any OTA updates however here is a procedure for any who want a non-stock recovery:
Currently I see TWRP has support for this device so the instructions here will install that recovery.
Option 1: Download GooManager from the Play store. Once installed click the menu and select "Install OpenRecovery Script".
Option 2: Download the TWRP recovery image here. Copy it to the /sdcard of your phone.
Connect your phone to your computer and use adb
type adb shell
once in the shell run su
then
dd if=/sdcard/openrecovery-twrp-2.3.1.1-t0ltespr.img of=/dev/block/mmcblk0p9
Alternate if unfamiliar with adb commands
Grab android terminal emulator from the play store and run the same commands starting with su and then the dd command.
De-Bloater
If you've made it this far with a stock, rooted phone with CWM or TWRP and you don't want to flash a custom rom (which will do its own de-bloating) you can check out my mrRobinson Note II De-Bloater to easily get rid of bloat system apps you no longer want to see. Simply flash in CWM or TWRP like anything else and you will be presented with a menu system to choose what to remove. If you are unsure it is safe to pick Minimal and still get a decent de-bloat.​

History:
I've injected root into other stock images and those threads have a lot of valuable information which could answer some questions that may arise here. If you have time to do some reading here are a few of the informative ones:
Samsung Galaxy S3 [ATT / Bell / Telus / Rogers / Sasktel ]
Samsung Galaxy S3 [TMO / Wind / Mobilicity]
Also did sprint and vzw but there isn't much there that won't be covered above.
FAQ
Does this remove the Sprint bloatware?
A: No. It is same as stock, nothing is removed.
Does this use an unsecured boot.img
A: No. This flashes the stock boot.img in the VPALJ1 image.
If my flash counter has been tripped, and I flash this and reset the counter, will it stay at 0.
A: Yes, as long as you don't then flash a non-stock recovery.
Can I still get OTA updates?
A: Yes if you do not load a custom recovery or remove any system apps OTA updates will still come and be able to be successfully applied. If you want to retain root through the OTA process I'd recommend trying the SuperSU survival mode.

Thanks I only asked because I figured if it could be injected as in tricking the phone this is coming from the manufacturer you could also tweak other things and still get away with it. ..Also without an OTA released yet can you say 100% an OTA will go through with no problems if we used this Thanks again

maybe im just a lil special at the moment, i haven't tripped the flash counter yet i learn something when i had the s3 i think that after you flash the tar for the recovery wait till its done (uncheck reboot before u flash) and then pull the battery and it doesnt trip the counter. if im wrong someone please correct me.

Just wanted to let everyone know I did this method then accepted the OTA update and I'm still rooted. Thanks for this!

Very nice! Thank you very much! This will make it easy to go back to stock AND have custom recovery!

Its not just a recovery. that's a root method that trips the counter. Maybe you responded in wrong thread.

if you have a root explorer go to /system/etc and delete the install-recovery.sh file you see there. Or just rename it something else like install-recovery.bak

[Q] Download Mode Tweaking Out

I was rooted, i unrooted and verified with the terminal emulator and entering "SU" to ensure that. i attempted to update to 4.1.1 from 4.0.4 but when i do so, it boots into TWRP recovery. I attempted to enter download mode, only to have it appear and before i can touch the volume up bottom if fades away. Any Help would be appreciated.
Yes, i am a noob, thats fine with. Everyone was at one point. so help a brother out.

How were you updating to 4.1.1? Through a stock/stock based rom?

Also, you have to have stock recovery (not TWRP) for updates to go through. If you flash http://forum.xda-developers.com/showthread.php?t=1904099 in TWRP it will restore you to the latest unrooted update and will give you stock recovery.

Help for a somewhat new person.

I am new with rooting my phone. I have used Rooted phones before, I followed http://forum.xda-developers.com/showthread.php?t=2258633 Motochopper how to. I ran into a problem. I click the superuser app that was installed onto my phone, and it tells me that "The Superuser binary (su) must be updated. Please choose an installation method. Recovery mode installation is recommended for HTC devices." I click install and it tells me there was an error. I would like to root my phone along with potentially installing CWM so that I can easily install Cyanogenmod when they release a stable verison for the S4. Also would love to install titanium backup along with some Adfree apps.
Any help would be very much appreciated.

OK, so it looks like you already have it rooted.
When super SU asks that question, dont install via CWM, tell it to just install normally.
Once you have SuperSU working, Download Rom Manager from the play store and install CWM Recovery right from within the ROM Manager app.
It will give you the option to pick between two types of CWM(ClockWorkMod). The Touch version, like its name gives you the ability to use the touch screen and not only the volume up/down + Power button.

Telling it to install normally causes it to just tell me there was an error, it also tells me it is out of date as well. Titanium Backup tells me that it cant get root access and I was never asked about it.

OK, so your phone is not rooted then.
Your going to have to try rooting it again or flashing an already rooted rom with Odin.

I just tried it again, this time it said failure after the install of the superuser.apk. I just read that one of the later updates by samsung can make it harder to root. I just got my phone and i was fully updated. What Roms, are already rooted for the S4. I am actually enjoying some of the default apps that came with the phone.

Wicked (and most ROMs that don't include the [STOCK] tag) are pre-rooted...but you'll need to ODIN a custom recovery first then flash the ROM.
If you want to stay on rooted stock, follow the steps in the "root May 7 MDL" thread to ODIN a rooted kernel, and you'll be good to go.
(You don't need root access to get a custom recovery flashed)
Basically, any of your options are pretty straightforward, but they're going to involve Odin-ing stuff.

So there isn't really a way to just root my phone without installing a custom rom?

Are you still on the MDB firmware or have you done any over the air updates? Specifically the May 7 update which is MDL. Motochopper is specifically for then older firmware (MDB) and it won't work if you are already on the updated. MDL firmware. In which case you would have to follow these instructions to acquire root.

I usually use a market app called root checker to quickly check if I do have root.
And yes you can be rooted on stock.

Root checker says no root. I believe it does have that over the air update installed. T Mobile updated it when they gave me the phone, because they thought I didn't really know anything about phones. I assume this means I have to follow another method to root my phone?

This is going to sound like a dumb question but from reading all of that I need to use ODIN to install the ROOT_M919?UVUAMDL onto the phone? that should root the phone and allow me to install ROM Manager and install CWM from there right?

No, you use Odin to install one of the recoveries. You use the recovery to install the zip ROOT_M919?UVUAMD. Personally I didn't use that file. I installed the kernel in recovery and SuperSU in recovery. And no, it won't delete things on your phone.

Thank you so much, I am about to go and do this. I will use the kernel you suggested since that looks like a better option, after flashing the kernal should i reboot and just use it normally for a bit and then go to recovery and flash SuperSU?

2 options. uncheck auto reboot in Odin. When Odin is done, unplug your phone, pull your battery, then boot into recovery. Or .. when Odin is done and it reboots your phone, keep holding volume up to get to recovery.
