[Q] [G900H] Partial rooting problem - Halfway root

Hi all, thank you for reading this. I'm sure I'm not the only one here that has this problem;
I've got a Samsung Galaxy S5 SM-G900H and I've tried countless times to root it. It rooted halfway. How? Well, being a n00b in a developer's forum is really tough but I'll try to exemplify:
So I succesfully rooted my phone via Philz CWM to later install Chainfire's Root App from Google Play store. But I can't run "Game Killer" without it posting "Root access needed" when I THOUGHT I rooted my phone. So I downloaded Root Checker Pro and then I kinda understood why.
Has this happened to anyone before? I've never had this rooting problem (used to own a Galaxy S4 before this one and a Samsung S2 before that one)..
PLEASE HELP!
Oh, and I can't use CF-Auto-Root method because it get's stuck at CACHE and I can't make it past there (EVEN if I change the Odin versions). My guess is that it's got something to do with Philz being there. I dunno..
HOW CAN I COMPLETELY ROOT MY BELOVED S5 G900H?
Thank you in advance!

Bump?

Yes and yes. Incomplete roots are a common issue and happen to many people. It can happen because you missed a step, because the rooting method is out of date or perhaps some app is interfering. You simply need to root again.
It would probably suffice to update SuperSU and update or install busybox. But if you prefer, uninstall SuperSU, then run your root again. If you run into difficulties, then look for advice on how to disable Knox, use one of the newer rooting methods or flash a stock firmware image and start from scratch.

2 ways:
1) This has been noted before. If you get stuck on the cache during the flash process, you should remove battery + sim + sd and re insert them and flash again.
2) Not being able to flash with Philz usually is caused because of the recovery version. Since you have G900H it could very be that problem, so if you didn't try my advice from above, I would try to use a different recovery (CWM / TWRP).

Thank you YMatrix for taking the time to respond. I will reply as soon as I'm able to do so and post a reply with the steps for the successful alternatives.

Nope. Did not work. I made a full wipe, formatted system, formatted data, formatted media, formatted cache, made a full full wipe of everything, flashed original unbranded firmware and then followed the CF-AUTOROOT method to encounter the same fail...

Is there a manual way that I can copy the su file into system and set the setuid permissions?
I'm doing my best and tried everything and nothing and no way seems to grant me core root like it's supposed to..
Sent from my SM-G900H using XDA Premium 4 mobile app

Just an idea,, why not unroot then use towel root? I didn't need to go to all that trouble to root my device. Just a couple of clicks with towelroot app.

Because when I attempt to root with Towelroot it says that my device is not currently supported..
I've tried almost every combination/steps.. It gets rooted but it doesn't root the core.. I don't know how to put it in words. N00b disadvantages..

Hmm in that case I would post a message on the xda-dev forum. Oh wait
Sorry I'm not much help here. I'm not sure why my Australian S5 is supported and yours is not (towelroot).

Well, I'm not sure either. One very strange thing as well is that in Terminal Emulator, when I type "whoami" it says unknown.
I still can't access full root.
I do, however, have SuperSU installed and working properly but it's like a fake root or something..

The result is still the same.. Help? Please?

Well RBucci, i'm with the exact same problem. thought semi-root, happenned to me before, with the S4 and S3, i ve simply fixed it, re rooting with another version of CF-AUTOROOT.
But now, there's no other version of it, for S5. i have the same varian (G900H) as you. CF-ROOT get stuck after writing Cache.img, and throwing "Write error".
please, let me know if you find a work around for it, i'll be doing the same.
i guess we have the same phone, i'm from argentina, probably we have the same variant of "H" version..

Question, have you tried downloading busybox from market and trying to install it?
does it erease itself after rebooting?

Finally working full root!
as you asked here is what i've done.
put a sim card in the phone, (never put a simcard in the phone before), enter developers options, marked USB debbuging, unmarked verify potencial risky apps pushed by ADB (sorry if the translation isnt exact i have the phone in spanish) is right below USB Debuggin Option.
-turn off phone
-Remove SIMCARD
-Enter Download mode
-Flash via Odin 3.09 Chainfire CF-AUTOROOT for G900H
-and enjoy.
try it mate. it worked for me

here some screenshots, one checking root, another one checking busybox.

Hopefully I'll be posting back from a fully rooted phone.

failed flashing Resurrection-Remix-LP-v5.5.9-20151121-jfltexx.zip ROM

Hi. Today I wanted to flash my s4 I9505 device with this ROM http://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-resurrection-lollipop-v5-5-5-t3195202 but at the end the problem has popped out. I had an android 5.0 lollipop don't remember which one exactly. First I've rooted my phone with odin 3.07. Then I've downloaded ROM Manager (https://play.google.com/store/apps/details?id=com.koushikdutta.rommanager) from Play and installed recovery. It looked like this: http://www.pocketpc.ch/attachments/...ry-fuer-galaxy-s4-mini-gt-i9195-wp_000062.jpg. Then I wiped cache and data. It appeared with totally clear phone. Then I installed superuser from the recovery level and then problem appeared. The phone is booting up normally but after all the starting logos it comes with black screen and multiple crashed of Multimedia, Camera, Interface and so on. Is it bricked? I don't know what to do, I have to say I am kinda newbie. Hope that someone will help.

You can disabled the boot loop and heating up by factory resetting your phone after flashing the engboot, once this is done do the entire initial setup but when prompt with hands free activation hold the back button. Go to the play store and download package Disabler Samsung. Now go to settings and activate device, when finished do not hit "done" instead hit the home button. Go to package Disabler and search DM services, disable it and wala! Enjoy!

So I have the 930T ,I flashed the Engboot then phone restarted. After the start up process I went to push supersu via adb, it went through the the whole process and success. The phone rebooted automatically and after it booted I could see the supersu app. Root checker says root not installed correctly and also titanium back up won't detect root. I have downloaded and pushed the files a total of 6 times. I have also wiped cache before the last push, still no root. Any ideas?

Did you try to reflash su

Yes 7 times now.this last time I reflashed the Engboot and did the whole process. Same result.

It's definitely tricky but this works. I've done it to mine 3 times to get everything right. I'm on pd8 by the way.
Here is how I got everything working smooth.
Make sure you have the modified Odin from the original AT&T thread.
Take out the Sim and memory card if you have one. These have caused issues in the past.
Factory reset in recovery. Then boot into download mode. Flash via Odin the 930t pd8 firmware or whatever version you have (from sammobile, 2hr download with a free account) make sure. To use the "Home" csc file. Again we are flashing all the fields.
Now your stock.
Boot up and setup your phone. Still no Sim or memory card. Install kernel auditor, titanium back up and busy box.
Turn on adb mode via developer mode.
ADB reboot download mode.
Flash everything again but this time using " Samsung_G930x_QC_Rooted_boot.zip" in the AP field in Odin.
It will reboot, then once abd is able to see your device. Run the root.bat.
It will reboot after a time.
Once it's back. Install busybox to system/bin, it won't install to xbin.
Use kernel auditor to change cpu governor to "ondemand".
Use titanium back up to freeze "security log agent"
You should be golden.

How is the lag? Did you notice any performance loss? I followed the steps in the original thread and had to factory reset after being stuck on the Tmo screen (Huge over site on Tmo to add a white splash screen on an AMOLED screen...). After I flashed SU, superSU would lag like crazy. It would take 2 mins for root requests to popup. I never felt so happy to odin back to stock after that. I didnt think of flashing all odin files and just replacing the AP slot. Maybe that will make a difference?

I had the same problem all is good now just let your phone rest so it can learn battery usage and download no frills cpu or any goody kernel tweaker and change govn. To interactive this will help lag. You just have to let phone sit it will fix itself.

I'm not sure but usually you can go back between versions, LP to LP, MM to MM. You just must try, you won't damage your phone, Odin will just print a Fail Message. Be sure to have latest one, as you may get a soft brick.

I had the same problem (stuck on the Samsung screen). I tried reflashing, but that didn't work. What ROM were you coming from? I'm trying to "downgrade" from CM 7, since I'd like to be able to access the sensors and SMS not working doesn't seem like much of an upgrade.

I had the same problem, 3 things I did to fix this:
1. Take out external SD card, the Android directory on it will cause bootloop
2. Before Odin the new firmware, boot into recovery to do a factory reset and wipe everything including internal SD card
3. power off phone, then reboot to recovery using power-vol down-home
The bottom line is to keep your phone in factory-new mode before Odin the new firmware

Help!!
I've bricked my s7 edge!!
I was trying to flash twrp recovery on odin and ended up stuck in a bootloop. I think I've deleted everything off my SM-G935F. I thought I'd have to resort to reflashing stock rom off sammobile but it doesn't seem to want to complete the download for some reason. It keeps stopping about 3/4 of the way through. It takes about 2 hours to get to this point and it happens every time. I've tries it a few times from sammobile and even 2 or 3 other websites. I've tried different roms O2 and btu and xeu. I'm from the UK using an unlocked unbranded version. Can anyone shed any light on this issue or tell me some other reputable website I may find a working link to a stock rom?
Thanks in advance guys.

Hi. Thanks for the reply. I'm sorry but I'm an amateur when it comes to this sort of thing. I'm not familiar with smart switch..
How does this work exactly? I can't download it to my phone because it's bricked. Would I download it to my laptop?
I've also been trying the fw.uptado.com website but it can't be found for some reason.
Anyone else able to help?
I apologise if this is basic stuff but I've only rooted about 4 phones in 7 years so I'm not really any kind of expert to say the least .

This is the unbranded firmware: http://updato.com/firmware-archive-select-model?record=145291997DB511E7963AFA163EE8F90B
Put your phone in download mode as you did when you flashed TWRP and use odin to flash the AP from the zip file in that download.

Sometimes downloading with "stock" downloader of Windows, and Android sucks if you have unstable internet connection. My suggestion is to use the Internet Download Manager for Windows, or the Android Download Manager (ADM) obviously for Android. Good thing for these aforementioned download managers, if your internet connection drops, your ongoing download will not terminate, instead it will resume where the point stopped.
PS: just tick the option of "Auto Resume" in the Settings.
Hope this helps.

Thank you everyone who has gone out of their way to help me out it's much appreciated. After lots of failed rom downloads, I finally managed to find one that finished downloading. I've flashed it and realised it was an unbranded Swedish rom but it seems to work fine.
On a side note I couldn't seem to install magisk and samsung anti root via twrp. I kept getting an error message saying "failed to mount data. Invalid argument"
Anyone know why this is happening?
Thanks again everyone.

after flashing twrp u need to perform a format from the twrp recovery. i.e wipe>format data type yes. only after that can u flash a rom or any other file. u need to perform this step only once.
oh n when u reboot the phone select the do not install option.
also it would be better if u flash a custom stock rom like superman or batman. flashing magisk on oem stock rom sometimes makes the phone sluggish. in my case the phone not only becomes slow but lucky patcher causes the phone to reboot.
good luck flashing

For the first time coming from stock firmware, /data partition is encrypted and can't be read by twrp. To fix this, twrp need to format(not wipe) /data partition to remove encryption once.
Keep in mind, that all data will be lost.

also it would be better if u flash a custom stock rom like superman or batman. flashing magisk on oem stock rom sometimes makes the phone sluggish. in my case the phone not only becomes slow but lucky patcher causes the phone to reboot.
good luck flashing
