Unrootable Galaxy S4? - Galaxy S 4 Q&A, Help & Troubleshooting

I bought a new S4 (GT-I9505) recently and have found it impossible to root.
I've tried the following methods:
Philz TouchWiz (various versions)
TWRP rooting
CF AutoRoot
Whatever I try, the flashing via Odin works, I can usually reboot into recovery and root it, and then the next time the phone reboots it's back to the stock recovery and root is gone.
Has anyone encountered this problem, and/or does anyone have ideas on how to resolve this? I've effectively got a new phone lying around that I can't use because I can't root it.
Thanks,
WA

When you root the phone, are you able to boot and have root access? If so, try that then download the TWRP Manager and flash TWRP using that app. See if that sticks on reboot.

Try this: uncheck everything in Odin except f.reset time. Copy supersu to the phone, flash twrp, when you see the word reset in the status window, remove USB cable, remove battery, boot into twrp, flash supersu, reboot.

[Q] Unable to install Custom Recovery

Hello,
I am facing weird problem, I am not able to install custom recovery, I have tried almost everything.. nothing helped.
I am still getting stock recovery..I have tried to flash it via Odin, via some apps, unfortunatelly nothing worked.
My Samsung Galaxy S4 i9505 is running KK 4.4.2.
Any idea?
Thank you.
I had this problem too. keep flashing cwm recovery through the app (needs root I think). and reboot into recovery, once you get cwm you can flash a custom rom or another recovery like twpr or philz.
s4 i9505 stock KK
I have that problem too. I have stock KK 4.4.2 XXUGNG8 updatet ota. When i try to flash flashable zip file cwm of philz or twpr i get some error like:
E:footer bad
Mds check
Something like that and cant flash it. I tryed with odin but no luck. Does anyone have same problem?
I had this problem to
I fixed it by checking te root options.
If u use a root app, make sure it gives always root acces.
After this, install a custom recovery rom
After that you'll have no problem installing a custom ROM
Good luck.

But my phone is not rooted, its new, with stock recovery, knox 0x0 still....
Have any idea?
Ok, but what if my phone is not rooted, how am I supposed to root it? When I tried CF-Auto-Root my phone started to reboot randomly during the phone call.
I have found one solution, but I am not sure if it works, it says that if you are flashing custom recovery via odin, you have to take out the battery after the flash is done so you won't allow your phone to restart and rewrite the recovery back to stock. Have anyone heard about it?
No, no idea.
Thats crappy.
Only know how I fixed it

Just uncheck auto-reboot before you flash the recovery. That will fix your problem.
I have tried it, but it didn't help still looking for solution, is there any way how to RENAME RECOVERY RESTORE FILES so I can finally flash custom recovery? (non-rooted phone)
OK, so the solution that worked was simple and I have already mentioned it, you have to take out you battery on samsung galaxy s4 logo, before it reboots.
My solution
Hi I had the same problem too,
I solved it this way: (My phone was rooted)
Download the .zip file from the recovery you want (I used CWM 6.0.4.7)
Next download 'SGS4 flasher' from the playstore.
SGS4 flasher needs root (I think) andyou can flash your recovery through that app.
Next boot into the recovery and you should probably end up in your custom revovery every time now.
If you don't end up in your custom recovery, download ROM manager and then choose the option boot into recovery.
This worked for me at least :laugh:

[Q] Solved: No recovery

New to the S4 - did a search and could not find a similar problem as mine...
My friend gave me his S4 and told me it is rooted - which it is. However, there seems to be no recovery on the phone. When I try power-vol up-home, I get the blue recovery note at the top, but then the phone just continues to boot into the system (MF9). I used Odin to go back to stock and then attempted to boot into recovery - no luck. I rooted the phone again via CF Auto Root and tried to install a custom recovery via Odin and TWRP Manager - still no luck. Anyone have any ideas/suggestions? I appreciate the help.
Bumping this up to the top for one more run through...thanks everyone.

Maybe go in to Odin mode and flash latest stock making sure to unchecked the auto reboot option. When it finishes flashing unplug and pull the battery, let it boot it'll take a while (took mine about 10-15 minutes). You'll then be on latest stock with latest bootloader and recovery. From there you can go back to Odin mode and flash TWRP. Once again making sure to not auto reboot.
Just to be safe back up apps and msic and picture etc on samsung kies and then do a full recovery delete everything and install the latest firmware then try cf auto root again or if you have trouble with that rhen use kingoroot and then flash twrp or phils recovory and get a rom. If that doesnt work just get cyanogenmod installer which installs root and a stock rom.

Thanks mattzeller. Your suggestion took me back to my Evo days. I took out the sd card, flashed with Odin, pulled the battery, rebooted the system, and then was also able to boot into recovery.

Troubles installing custom recovery on Note 4 910G

I have a Note 4 - 910G (India) currently running 5.0.1
I have managed to root the device. I can confirm that I have root access with an app like root checker. And yes, I've managed to trip Knox. At the custom boot screen, it shows Knox status as 0x1 (4).
My problem is that I can't install TWRP or any other custom recovery. I have followed the usual steps to install a custom recovery with flashify, TWRP installer and adb commands. Each time I try, the device reboots into odin mode (high speed) mode only. I then have to flash a custom recovery with Odin and the device reboots. However, even then.. if I try to boot to a bootloader, it still goes into the odin mode.
Is my device completely borked? Can I still install TWRP and then CM12.x on the device?
Any help/pointers would be appreciated.
I too have a note 4 sm-n910G. I think ur TWRP file is corrupted or you got the wrong file. It should be easy to get custom recovery. I rooted my Note 4 using CF auto root and it had CWM recovery which i tried to flash in Odin but it wasnt working. So i changed to TWRP 2.8.1.0 and it worked perfectly. Maybe try changing the TWRP file, or use a different one like CWM or philz recovery. Good luck...

Galaxy Note 4- Can't Install TWRP

Note 4 Can't Install TWRP
Hello,
I'm in the process of installing a recovery mod rooting my root 4.
When I try to install TWRP using Odin, I don't get any error messages, it says PASS, everything looks okay.
When I try to boot into recovery, it shows the android bot with the message (installing system updates) under it, and then it loads the default samsung recovery instead of TWRP.
I made sure that I have the correct version of TWRP downloaded (N910H Exynos version, named twrp-2.8.7.0-treltexx.img.tar). I aslo ran Odin as administrator, but it's still not working, the knox counter was tripped however.
Any help would be greatly appreciated, because I can't proceed with the rooting process without TWRP.
Did you root your phone before flashing the recovery?
EDIT: By the way, when you have flashed the recovery, you MUST immediately boot into recovery, or else the stock rom will overwrite it with the default recovery.

SM-G900S bootloop after trying to root

Good afternoon guys,
i have a big issue with my galaxy s5 SM-G900S (korean version). I bought it as a refurbished device. Knox was on 0x1 so something may have been modified.
It came with the stock (?!) android 4.4.2 from march14. I tried to update but it returned a registration error. Probably because knox is 0x1
In any case, I activated usb debugging and tried to root the phone using cfautoroot and the corresponding root file: CF-Auto-Root-klteskt-klteskt-smg900s.zip which I still assume to be the correct one.
I used odin for flashing. The device was properly connected (blue).
Everything seemed to go smooth until the phone restart when it said "recovery is not seandroid enforcing". I tried several times with both odin 3.07 and 3.09 but i cannot pass this step. I also tried the method to untick auto reboot, shut the phone down manually and boot into recovery mode but it failed.
This means I am now stuck in the bootloop. I can access download mode, but i cannot reach recovery mode. Also the phone is not recognized by the computer if i try to connect it to adb, kies etc. Odin seems to connect properly still.
Alright how should i proceed now?? My actual target is to flash a custom rom. I will need to go for a dirty flash now correct? Should I flash a stock rom with odin? If yes, which one?
Please support me a bit, I am very frustrated on this topic, especially cause I still dont realize my mistake......
Merry Christmas and greets from Bavaria, Germany.

Flash the stock firmware to get out of boot loop. After flashing the stock firmware, everything should be working fine and booting again. Instead of using CF auto root, flash a custom recovery like TWRP and then use it to flash the SuperSU zip.

Alright, Im back to stock android 4.4.2 now. Works perfect, aside from registration. If I click on "update now" it shows: SKT-USIM required.
Can someone link a detailed guide for flashing cm13? I checked the web but i still dont entirely understand.
In any case I do not want to risk going into a tricky situation once more.....
Thanks in advance.
Greets, cheet
