I can't seem to root

I went back to odin to get a fresh of my gs3. I did the 4.1.1 update and now i have an issue.
I can't seem to install any recovery on my samsung galaxy s3 in order to root it.
I have tried just about all the downloadable clockworks out there and even tried twrp...its no go. I do not know why this is happening because I never had this problem before when rerooting my gs3.
Any one faced this before? suggestion?

You need to flash recovery via odin.
If you want just flash root66 lastest firmware which is in rooted version too.

Stock recovery is overwriting your custom recovery. Need to access recovery mode after you flash, but before the device can boot (so that the custom recovery can disable to automatic flashing script).

I am not quite sure what you are saying here about needing to access recovery mode after I flash...I flash the clockwork recovery mode and when i go to access it, i only see the stock.

I i reflashed odin again and decided to root using 4.0.4 ics...now it worked..I guess we can't flash over 4.1.1 anymore?
anyway, thank you both ^.^

The problem is with the newer roms, when your phone boots, your custom recovery is overwritten with stock recovery. This operation is done with a script that comes with the newer stock firmwares - it's built into the startup procedure. So when you flash a custom recovery with Odin, you need to drop to recovery mode before the phone ever gets a chance to boot into the OS, so that the custom recovery can disable this script. If the phone boots, it will wipe out your recovery. Do you understand now?

Oh now that make a lot of sense. So I was not suppose to reboot before going into recovery with 4.1.1...will keep that in mind next time!

Even though you're rooted, flash the 4.1 root66 in Odin. You don't want to go from ICS to JB via recovery, it doesn't flash all partitions. After you flash root66 in Odin, you will already be rooted. Then you can just flash a custom recovery.

If I remember correctly you can still root normally on the later builds, you just have to pop out you battery after you flash, don't let it auto-reboot, then you can put the battery back in and get to clockwork recovery.

Enough said. You need stock recovery to do OTA.

Try to locate OTA file and flash it manually

You won't lose root if you have stock recovery.
Do you even have a stock recovery? If so, just place it inside the adb folder, open the command prompt change directory to adb folder, boot into bootloader mode and type fastboot flash recovery name_of_recovery.img The same way you probably got custom recovery onto the device.
Won't lose root because of stock recovery. You'll lose root because of the OTA though, but even then it's easy enough to regain root. You can then either flash back the custom recovery OR boot the custom recovery. I'd suggesting booting the custom recovery that way you can make a nandroid backup of the updated system before you flash anything again.
fastboot boot custom_recovery_name.img If you're using TWRP then it probably won't make a backup of the stock recovery, CWM/Philz will work better for the nandroid. After you made a backup(If you choose to make a backup, again strongly suggested) then you can flash a custom recovery again.

4.4.4 to 5.1.1

Hi folks,
can i go straight to this? my tab is rooted. IF i was to unroot then download the full rom from google, and flash the system, recovery and boot, would this be ok, what i mean is, it doesnt have to be iterative to the latest version does it?

What I did was the flash the bootloader 4.05 and Scrosler's Stock Rooted Busybox 5.1.1 ROM http://forum.xda-developers.com/nexus-7-2013/development/rom-stock-rooted-5-1-1-lmy47v-root-t3098137. Follow his instructions or if you want to dirty flash, use TWRP to first wipe the 2 caches, flash the bootloader and then ROM, wipe caches again and boot to system. The first boot is very long.

You need to flash the bootloader as well since it got updated.
No need to unroot, you're flashing the system image..
Bootloader boot and system will do it, I'd recommend a clean install though. Flash all partitions or run flashall file letting it wipe the tablet.

ok thanks folks. didnt realise the bootloader had to be done too. I guess this also applies to my N5 when im updating that too?
SO .... if i was making instructions to flash my devices for future updates, would the following suffice?
dont unroot
dont remove TWRP
fastboot flash bootloader bootloader-hammerhead-hxxxxxxxx.img
fastboot flash radio radio-hammerhead-xxxxxxxxxxxxxxxxxxx.img (do i need to even do this?)
fastboot flash boot boot.img
fastboot flash system system.img
boot to recovery and wipe dalvik cache

scrosler's ROM is standard 5.1.1. The beauty of it is that your phone will be rooted and busybox installed (with a trim). Just use TWRP to wipe whatever partitons you want (the 2 caches and also data if you want a clean install), then add bootloader and then ROM zips to the queue. Install them, then wipe the 2 caches again and boot to system. You might have to install SuperSu again from Play Store but you will be rooted.
It couldn't be simpler

How to extract recovery images from existing roms? Or is there a working TWRP site?

The recovery images all over this site seem really sketchy, but roms often come with great recovery and updates. I can flash the rom's boot.img during the update, but I also see that fastboot has a flash to recovery option. Is it OK to flash the boot.img to recovery or do I have to somehow extract recovery out of the boot.img? If I do a flash to recovery does that make TWRP permanent or can it still be overwritten by flashing new roms?

Get twrp from here - http://forum.xda-developers.com/sony-xperia-z1-compact/general/twrp-3-0-1-amami-t3350827 and flash with Rash for non-stock roms. For stock roms, net's xzdr is best - http://nut.xperia-files.com/
If a rom has a recovery included, it will probably overwrite your recovery. For best staying power, make sure you use real recovery - http://forum.xda-developers.com/son...ral/bootloader-devices-real-recovery-t3117568 but even then you might still have to reflash your img, depending on the rom you install.

Thank you so much. I had the latest TWRP from the AICP rom but it was within the boot image and I couldn't seem to find a plain TWRP image that wasn't on some sketchy thread.
Also I was unaware that my firmware was out of date. When I was installing a rom I saw a number that related to the latest firmware so I assumed I had it. I was confused why using flashboot to flash to recovery wasn't working. It looks like the recovery image was always within the boot image and was getting wiped out with roms that didn't include a recovery image in there (AH HEM PARANOID ANDROID). It seems that I was able to flash the img to the special recovery now and I don't think it's getting wiped out. Thanks very much.

TWRP gets overwritten

I'm on latest ob18. I am able to flash it, and run it once, but after reboot, the stock recovery gets Back. Any ideas?

Just Reflash twrp via flashify or adb in fastboot mode, that could be normal if u r flash an unmodified stock rom

Yep. On latest ob-Oos or H2o for me recovery stays, after instaltion of the rom. But on a second reboot, stock recovery shows and i reflash custom recovery again.

Guys I flashed latest H2OS beta over OOS Beta18 and lost access to recovery. These are the steps I followed, please help.
1. Backup current ROM (OB18)
2. Dirty Flash New H2OS version
3. Flash recovery image again
4. Reboot system
ROM booted without any problems and all my data is present but I lost access to TWRP.
Solution attempted: Reboot to fastboot and flash recovery image again, the process is successful but still TWRP is not coming up.
Please help. Thanks in advance

Stock rom always over writes recovery best way to get it to stick is flash stock zip than twrp reboot to twrp and reboot or flash mods/root
