[Q] CWM/TWRP impossible to install after upgrade to 4.2.2

Hello everyone,
My brand new n5100 came with 4.1.2 out of the box, but upgraded to 4.2.2 OTA immediately (XXCMI1).
Right after that, I tried to install either CWM or TWRP through Odin3, with no success. It says PASS, but when I boot in recovery (home+vol.up+power), all that I have is stock recovery.
Does anyone know what's going on? Any ideas on how to do it?
My final objective is to root the device. Framaroot exploits are no working anymore. Should I proceed installing a custom kernel? I am afraid of having a locked bootloader or so, and bricking my new toy due to that.
Thank you in advance!

Use CF Autoroot to root the device. Then install which ever recovery you want.

Root de vega vs. kingo?

Hi..sorry if this has been answered, but I don't see it on t-mobile.
I am planning to root my phone to run the regionlock (hopefully unlock sim). Getting confused with all the different methods available.
I don't want to trip Knox..was planning to use RDLV, but then read something about Kingo, but that wasn't listed as a method for rooting on the FAQ?
So what's the difference? Is one better than other? I also read that any installation of ROMs will trigger the knox? So if I rooted, how can I get to the newest firmware? Just unroot and update OTA?

If you are 4.3 you can root without tripping knox. I used RDLV I felt is was safer. XDA removed Kingo, it may not be safe. I know many have used it and are a big fan of Kingo. I did not like idea of some third party rooting my phone, they can do anything they choose to do. That is just my personal choice.
If you are 4.4.2 Kitkat, the rooting method available will trip Knox.
OTA, will not work automatically. You will need to use Odin. There are threads on how to all the above.
I am stock rooted 4.3, I have not jump on the Kitkat wagon yet. There are mixed reviews on moving to Kitkat.
Good luck and enjoy!

Thanks. if I stay rooted but want to move up to Kitkat but not use custom ROM, can I flash the offical firmware? And would that trigger KNOX? I read any flashing ROM will trigger it too? This is much more complicated...did this stuff a few years ago with HTC...now there's so much more stuff to consider

i think you can flash to 4.4.2 (KitKat) using odin mobile pro without triggering knox, at least that's what i've read on here that others have done successfully. if you want to upgrade you'll need to upgrade your bootloader too. keep in mind that once you do this, you can't revert or downgrade back to jellybean 4.3 or downgrade the bootloader (knox requires a signed bootloader to go with a signed official ROM, apparently).
personally if i were you i'd stay on jellybean 4.3 and use the root de la vega method. i'm a bit miffed mine came with 4.4.2 already on it.
i miss how easy it all was back on HTC too could root, flash recovery, ROM, kernel, and return to factory settings like new. *sigh*

Do you mean flashing 4.4.2 official rom which will become unroot again right? How about going to 4.4.2 and stay root with stock type ROM..not customized?

if you go the mobile odin pro route, it should root it again for you if it gets unrooted
you can get the steps on how to upgrade to 4.4.2 and keep root with knox 0x0 using mobile odin pro on this thread:

sprint galaxy tab 3 root for 4.4 ??

I currently just got the sprint samsung galaxy tab 3. When I activated it, it updated to 4.4 kitkat . I cant seem to find the root method for 4.4, can anyone help, I just flashed the old method and it obviously isnt working.

I am also having this issue. I just bought the tablet (SM-T217S) and updated to 4.4.2. I flashed TWRP with Odin and then flashed armeabi universal root through TWRP as per these instructions. I see SuperSU in my apps but it crashes on start. Apps that require root don't work also.
I need root so I am willing to downgrade Android for it but I would love to have root on the stock 4.4.2.
EDIT: Found the solution. Follow the instructions found here (same as above), then flash the SuperSU update attached here with TWRP.

[Q] How to root

Hi guys, I just got a galaxy s4 for t mobile and it came with 4.2.2 version of android. I'm scared to brick the phone but I really want to root it. Can someone point me to the right direction? Been reading some tutorials but they are for different versions of android. How do I root my phone without bricking it or tripping Knox?

4.2.2 doesnt have Knox. Use CF-Auto Root by Chainfire to root.

Thanks! Now it seems that cf auto root comes with a stock kernel and recovery. Is this changeable? Can I install a custom recovery and kernel after using cf auto root? Or should I find a different method of rooting for this? Are there any safe ones out there. It seems that a lot is outdated and I'm afraid of installing the wrong thing.

I don't know if towelroot will root 4.2.2, but it doesn't install a recovery.

You're calling a rooting method outdated while using the exact "outdated" software it was meant to root in the first place. CF-autoroot is as safe as safe can be. In fact, I know it still works for 4.3 and I THINK 4.4.2; it just trips the KNOX counter on them... still gets the job done though.
As far as your concern of installing the recovery; it first flashes its own recovery so it can use an exploit, then reverts it back to stock. I believe the kernel is untouched.
If your end goal is to move on to custom recoveries and custom ROMs you can bypass the rooting process altogether and go straight for the recovery/ROM.

This.
You really don't need CF Auto Root at all until all you want to do is root the stock rom.
If you want to install a customer rom, use Odin to install a custom recovery and flash whatever you want from there.

That's precisely my end goal. And I guess my question is how to do this safely with the Android version I have.
I didn't mean the root method was outdated; I was talking about some of the information that's on the general forum regarding root. There is even a post on one of the stickies asking for updated info in May. This scares me because for all I know I can follow one of these methods to root or install a custom recovery/rom and end up with a brick because something is no longer compatible.
I guess my question is: what is the best (updated) method of installing a custom rom/recovery for my tmobile s4 with android 4.2.2?

Use cf autoroot and flash clockworkmod through Odin. Download rommanager. Download a rom. Hit install rom from SD card. Pick your ROM from downloads.

I understand your apprehension, i really do. What I've said to do has worked for me when i got the phone over a year ago, and has worked here recently when i did it again. I'm trying to tell you there is no need for an updated way of doing what you want. If you want root, use CFauto root. Like i said, that method was done specifically for MDB and MDL firmwares, there is no better choice. Newer yeah, but better? Not a chance. Your firmware is equally outdated and it's worked for millions of users without fail.
As far as a custom ROM goes, find one you want to use, put it on your SD card, pick a recovery (CWM, Philz, or TWRP), flash that in Odin, boot to recovery (power+volume up) , do a full wipe (system, data, and cache) select the ROM, and flash. No need to root at all if you want to go straight to a custom ROM.
EDIT: Obviously, you might want to perform a nandroid backup once you flash your recovery... but that's really optional as long as you have the stock Odin-flashable firmware. Totally up to you.

[Q] Root I9190 on 4.2.2

Hi,
First time poster...
I recently upgraded from a rooted HTC One V to a Samsung S4 Mini (I9190) on JB 4.2.2 - firmware I9190XXUBNA1.
I tried rooting with towelroot v3 - device not supported.
CF Auto Root only lists a KItKat 4.4.2 I9190UBUCNG1 file on the site - can I use this to root or will it brick my phone? Or must I first upgrade to KitKat using a 4.4.2 firmware from Sammobile.com since the upgrade is not yet available in my country? I am really not concerned about tripping KNOX.
Another question - how do I determine if the bootloader is locked?
Having a phone without root is just not the same... Any advice will be appreciated

flash this recovery with ODIN
http://forum.xda-developers.com/showthread.php?t=2678420
then enter the recovery and go into the reboot menu and click reboot, then it'll ask you if you want to root your phone, then click yes. and you're done. if you don't have the supersu app installed automatically on your system afterwards, download it.
