problem rooting now cant get bootloader - Samsung Galaxy S7 Questions and Answers

I just tried to root my S7 using ODIN and CF-Auto-Root (I've done this before without issue).
It failed for some reason and now I cant get into the bootloader. Vol up Home and power takes me to an 'updating' screen then a yellow exclamation, and finally what looks like the stock recovery?
The only useful option I have is 'apply update from adb'
How can I root and flash TWRP from here?
Thanks!

Ok one step forward two steps back.
I made a mistake - I was pressing vol up not vol down to get into the downloader.
I've now flashed twrp-3.0.2-4-herolte.img.tar but the phone seems to be stick in a loop!
I can boot to TWRP ok, but when booting normally it just loops.

Ok I'm getting there...
re-downloaded and installed TWRP. It seems to have worked this time and boots the system normally afterwards.
But I still dont have root.
I also tried factory reset (from android menu and TWRP) both fail and nothing is reset.
I followed this guide http://www.stechguide.com/root-galaxy-s7-and-install-twrp-recovery/

If you have TWRP, then just flash supersu for root

Download the Superuser Binary .zip from the Internet and flash it through your now working TWRP Recovery..?
You managed to get the Bootloader working because you formatted the data and that deleted everything including the Root binary. So you just have to download it again and flash!
Let me know if I got you wrong in any way because this seems like a quick fix.

[Q] Major Recovery Issues. Try this solution.

I cannot boot into recovery. I used a rootkit to unlock my bootloader and root my phone. TWRP worked fine when i tried it out for the first time and than i forgot about it. Today I tried to access it and it would not work. When I try installing TWRP from GooManager it just says it will download but it never does and then after a while the app shuts down. I tried flashing clockwork mod recovery from Rom Manager and it downloads all the way and than says that a problem occured. Can somebody please help me with my situation. When I press the power button and the volume down button and it brings me to the bootloader and i navigate to recovery, it just brings an android guy with a red triangle. please help me. I just want a custom recovery. I don't care what it is. Either TWRP or clockwork mod.
UPDATE: I figured out I lost root access so I rooted again and I now an successfully rooted but I still do not have a recovery. I tried to boot into the stock recovery but it will not work. It just shows a red triangle. So than I got TWRP Manager and tried to install TWRP from there but it still will not work.
UPDATE: I got Rom Manager and I looked in it and it said that I still had TWRP when I really had no recovery. So than I saw the option to get ClockWork Mod Recovery. I clicked on it and it installed successfully! So if you are having this same problem. Good luck to you. I hope what I did works for you.

Glad you got it sorted. For future reference, that android guy with the exclamation is stock recovery. You have to press vol up and power to get the menu to come up.

Help with rooting

Hello...I"m hoping I can get a little assistance with rooting...
I'm following the guide from http://forum.xda-developers.com/showthread.php?t=2737724
I've installed the drivers initially on a windows 8.1 x64 laptop (i've since installed on a win 7 32-bit machine). I kept getting:
RECOVERY BOOTING
Recovery is NOT SEANDROID ENFORCING
Set Warrenty Bit : recovery
I pulled the battery and when I try to start the phone up it goes straight to this screen again.
I pulled the battery again, went into download mode, and flashed philz_touch_6.57.8-klte.tar recovery img and it rebooted fine (unlike the cf-auto root.)
Everytime I try to do the first step of the guide (cf-root), I receive the same message. Can anyone help or at least point me in the right direction? Yes i'm new to samsung devices but have been flashing htc phones for years...clearly this is a different process. Thanks again for any assistance!
ALSO....even after pushing the recovery img through odin (at least it seems to reboot my phone).....turning the phone off...and then holding vol up+home button+power DOES NOT take me into recovery...it just takes me back to the screen with
RECOVERY BOOTING
Recovery is NOT SEANDROID ENFORCING
Set Warrenty Bit : recovery
Is there anyone who can assist me?
EDIT
I went ahead and installed a the stock 4.4.4 from this thread:
http://forum.xda-developers.com/sprint-galaxy-s5/development/stock-rom-ni3-kitkat-rom-t2886171
This apparently restored my recovery img and I was able to boot into the stock recovery. I attempted the process of cf auto root again using this file: CF-Auto-Root-kltespr-kltespr-smg900p.tar.md5 and the result was the same. Immediately after it tries to restart I get:
RECOVERY BOOTING
Recovery is NOT SEANDROID ENFORCING
Set Warrenty Bit : recovery
I again pulled the battery and powered into download mode to flash a recovery. The file I used was: philz_touch_6.57.8-klte.tar.md5
This booted my phone back into the normal rom. I tried to use SuperSu but it says that I don't have root. I went ahead and reflashed the stock rom and once again I have stock recovery. Not sure why this is happening, but it appears that cf auto root is removing my recovery. I'm probably wrong, but I'm looking for input from anybody in this community.
Any help?
Solved the issue following suggestions from this thread:
http://forum.xda-developers.com/showpost.php?p=57022287&postcount=24
Instead of flashing cf-auto root first, flash the custom recovery first. Then let your phone boot up and then power it down. Hold up + home button + power and get into recovery...wait for few seconds as it will show the same message as before and then it'll let you into recovery. I selected reboot now and it prompted me for root...select yes. Done.
:good:
Still not getting root
I went through all the steps on CF's Auto Root listing and ended up with the same issue. I followed the above instructions to reset and was able to get the phone to reload fully. I have since been able to install TWRP, however I still can't get root access on my phone.
I can reboot to Recovery and get the same announcements. However, if I wait a sec or two it does proceed to TWRP, but upon reboot I get no root access. SuperSU won't proceed and root checker verifies that I have no root access.
Any suggestions?

Hmmm...so all I can suggest is the little steps I took. Flash the full rom again...ODIN the recovery (philz)...let boot up....shut down...and vol down +home button+power to get into recovery...select reboot...should be prompted to install root.
Worked
Got it rooted, thanks. Now to find a good ROM.

[Q] Stuck in bootloop, recover files

Hello.
Today my oneplus one was suddenly stuck in bootloop. This happened in the middle of the day when I rebooted my phone. My phone was running the latest update that came OTA (stock lollipop). Whenever I boot my phone it starts loading and suddenly a Chrome (browser) window appears for 1 second and tries to load a website. Afterwards my lock screen pop ups for 1 seconds and it starts to reboot. During the lockscreen I tried to unlock my phone as soon as possible, but it just reboots. (Any ideas about this weird problem?)
I CAN boot it in recovery mode by holding volume-down button and power button.
I CAN boot it in fastboot mode by holding volume-up button and power button.
Perhaps a factory reset will do the trick, but I don't have a backup of my files (because this happened so suddenly without me trying to flash/customize my phone). My first priority is recovering my files, because most solutions will end up in me losing every file. Unfortunately I've found little possibility to do this during the bootloop problem. I've tried to flash TWRP because it could make backups of my phone. I tried it through ADB/Fastboot, but it failed because my device is not unlocked (I can't go to settings and put my phone in developer mode and debugging mode). So I've read somewhere that unlocking my phone (bootloader?) through ADB will wipe my phone, which is exactly what I don't want.
Also I've tried this: http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061
But It also failed because my device was not unlocked.
Did I miss some steps somewhere or did I read something wrong?
Hopefully anybody has an idea to either fix the bootloop without losing my data, or finding a way to recover my files before wiping the phone.
Thank you.

Unfortunately you might be stuck in a catch-22 situation here. In order to access the files you'd need to unlock the bootloader, but in doing so you'd lose those files. Without usb debugging already enabled I can't see a way out of this.
Decided to unlock the bootloader through ADB. (bye bye data)
After I've unlocked it, I've tried installing TWRP.
Some minor problems occured but I can finally boot into TWRP through volume-down button + power button.
I've decided to download the stock ROM i've found on the OPO forums.
Couldn't acces my phone through normal methods, so I had to use ADB to push the files into my phone.
Installing the file through TWRP, wiped cache/dalvik and installed super user before rebooting.
After rebooting my phone is stuck on the boot screen now. (This also happened before I installed TWRP on my phone)
I've also tried this method: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
Also no succes. I'm stuck in the bootscreen where it says 'cyanogen'.
EDIT: Managed to fix it eventually through: http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (part 2) writing the command in TWRP.
Phone finally boots normally again.

Exactly what did you flash? Full filename please. No errors occurred?

Hopefully the stock cyanogen OS.
First I've tried to flash cyanogenmod 12 through TWRP (file is found here: https://forums.oneplus.net/threads/cm12s-yng1tas17l-installation-guide-review-change-log.304615/)
Afterwards I was still stuck in bootscreen, so I've looked for another solution.
Which made me find this guide: http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
After flashing this file (probably the same thing) the problem still remained.
Eventually after multiple wipes/factory resets (which did not solve the problem) I've entered the command in TWRP and after reboot it finally worked again.
So I basically flashed my phone twice, once through TWRPS and the other through the batch file (perhaps ADB?).
Also no errors occured which stopped the flashing and commands. Did have to reinstall TWRP and reboot instantly in it by holding the volume down button multiple times. This doesnt happen anymore though.
Only had to install google apps for CM12 (gapps), for which I used TWRP in recovery mode.
Currently reinstalling most apps on my phone and no problems yet.

Give up and go stock?

A burst of fearsome energy overtook me tonight and I just had to root my phone
Kingoroot, Kingroot, Towelroot etc didn't work. Then I read about this thing called TWRP.. sounds great, I said.
Unlocked the bootloader, got TWRP recovery going, tested it out, got ready to add SuperSU and the one that gets rid of bootloader unlocked screen.
Boot loop. Stuck on the Motorola logo. It aint going anywhere.
I've tried all of the suggestions I could find so far here, like using mfastboot to clear cache and user data. It's looking like a dead end. I was following the instructions on a youtube video so of course I didn't back up anything before I tried SuperSU Should I cut my losses and try the stock firmware, or could I do more damage that way?
This is going to ruin my weekend, isn't it?

If you can still boot to your custom recovery its really not a big deal. Just install the ROM zip of your choosing and appropriate gapps. If you are boot looped when it starts to reboot just hold in the power button for about 10 seconds till it powers off then press and hold volume down while still keeping the power button pressed. After about 5 seconds or so of holding both buttons stop pressing both together. If done correctly you should be at the boofloader screen.

Yes, I can get to the bootloader. Factory reset there and reset using TWRP doesn't fix the bootloop. That's kinda where I am right now.
Uninstalling SuperSU did it! I used the un-su zip file.
Do you have one of the following 1)Motorola USB drivers for your PC and fastboot or mfastboot/adb setup for your device? 2)ROM zip on your internal storage. 3)A USB OTG drive? Any of these will work. Let me know which you have and we will go from there.

It's ok, I'm back in business - the issue was the installation of the latest version of SuperSU. I used Install from SD Card in TWRP to install the SuperSU remover and it booted fine.
Taking my time now because I need this phone, I'm living in a new country. I backed up and tried an older SuperSU but didn't work - I suppose by doing a factory reset I might have done something that stops a root.
Edit: this http://forum.xda-developers.com/showpost.php?p=63615067
Download the latest stable build of super SU from Chainfires site here. http://download.chainfire.eu/supersu-stable
Then just flash the zip you downloaded in TWRP. You don't need the systemless version of SU if that is what you were trying to do.

I think that was the one that bootlooped it. I'll be doing a backup first this time
My main reason for posting my solution in this thread is in case the same thing happens to someone else. Removing SuperSU with that un-su.zip solved it for me.

TWRP Problem

Long story short, I tried to install TWRP with odin and my phone keeps restarting after I did the reboot from the recovery.
This is roughly what I did:
Installed the adb stuff and android studio(because I don't know if the adb stuff was installed correctly)
Do the volume button stuff for download mode
Connect cable
Open odin
Add the latest twrp file in the AP space and start
The phone booted up regularly ... I can't remember which thread it was but it said to remove battery then boot to recovery so I did it.
The instruction I followed said to advance wipe something but I accidentally swiped to factory reset then it booted back to recovery I think then I went back to wipe what I missed earlier then I tapped reboot and system and it keeps restarting all the time.
I can still enter the twrp recovery mode and the downloading mode.
I think it's a boot loop and I read threads where the simple instruction doesn't work and I haven't tried the command stuff.
Hope someone can help me.
