After root attempt, SM-G900T won't boot to recovery. - Galaxy S 5 Q&A, Help & Troubleshooting

Hello, XDA community.
I tried to root my Samsung Galaxy S5 SM-G900T with Chainfire's CF-AutoRoot, but each time I attempt it the phone won't boot into recovery afterwards. I have tried with and without a custom recovery, neither of which are working to fix the problem.
I'm running Android 6.0.1, and I have the latest T-Mobile updates from March 1st, 2017. Could my phone be the wrong version for the AutoRoot? If so, what should/can I do to root my phone while continuing to update my phone with security patches from T-Mobile?
I have tried factory resetting my phone, as well. Is there a certain version I should try with the AutoRoot (Like some version of Android 5.x.x, or 4.x.x of Android and then once rooted re-update to Android 6.0.1?)
I know there are numerous threads that are similar to my problem, but none are from 2017 and none are exactly my problem.
Any tips or suggestions would be great,
Thank you.

I figured it out everybody, thanks!

From my research I found that the error was probably from trying to flash the wrong file, and it must have been because I decided to really focus on one single post on how to root the SM-G900T and follow it exactly, and it worked perfectly! It was my first rooting though, and I didn't brick my device so I still see it as a success.
If you or anyone else is interested, this is the post that worked for me. It seems to be more up to date than any of the other ones I saw.

Thanks, but...
Used that method last time, but as I said after updating the phone I cannot get this to work any more :crying:
And, as a new member Im not allowed to post to that thread...
I have Avast installed, and for the firewall to operate it needs root. (one of the reasons to root).
Always worked flawless, and after the FW-update it still does... No sure why...

[Q] Can't get my N4 rooted after flashing the factory Android 5.0

Title says it all.
I tried flashing the 3 latest versions of SuperSU with no luck.
I'm using CWM to flash it and it goes well, but as soon as I boot my N4 - bam, no root.
Didn't have this issue with Android L Dev Preview. Everything went smooth as silk.
Am I the only one having this issue? Does anyone know of a solution?
Thanks in advance
i can't rooted android 5.0 releaded.

It works!
I entered all forums on the Nexus 4 category but skipped the General because I figured its not related to development/rooting etc.
Thanks again, you rock

Recover Root after CM 12.1 install

Hello hello,
So I reverted to my old i337 (ATT) because my S6 is defect and Samsung are hanging me out to dry (whole other story there). That being said, this i337 was on CM 11 4.4.4 but had the home-brew version, a slew of issues and so on. It did have root though.
I managed to install TWRP 2.8, CM 12.1 official build and it works flawlessly up until now. Except, I lost root. I'm puzzled too because running Motochopper tells me it's already rooted, and if I install Superuser form Play it seems to recognize the root, but then tells me I need to update, which fails. If I try to install any root app, nothing works.
Interestingly, I had to temporarily downgrade to CM 11 throughout this to troubleshoot a bug with GApps, and even after "losing" root to CM 12, in 11 I still had root! Back to CM 12 and out the root again. I've looked through threads and the only thing I found remotely close was to go back to 4.2.2 stock, then flash, then upgrade again... I'm trying to find another way since everthing else works fine...
Seems like it's a question of root method having changed in Lollipop, but that's really the extent of my knowledge.
As always, any help would be appreciated!

Did you enable developer options, then go down to root access and enable it from there?

Wait! So you have CM12 on your ATT S4?
I spent 6 hours yesterday and managed to instal golden eye 53. But I'd like to try installing cm12.
Can you point me the link of the relevant thread?
Thanks

Yes and I can say that aside from very minor bugs (such as I can't get weather to work) it's by far the best ROM I've had on this phone! The nice thing too is it's officially supported.
First you can download the ROM here; I used the last stable release for 12.1, right at the top.
For instructions I would suggest to go on the official wiki for the jflteatt, but make sure you are using TWRP version 2.8.7.0. I was on a CWM custom recovery which worked fine for 4.4.4, but when I flashed 5.1 it was plagued with crashes and GApps were completely useless - even if it did technically work. Trust me, this will save you a lot of time and it's not really mentioned anywhere.
Also stay away form TWRP version 3.0; when I tried to install it it re-locked my boot loader (somehow) and I had to fiddle-fsck around a lot with it to bypass it again.
But outside this, it was a flawless install for me! Hope this helps.

No problem man. There is also a setting in Super User to override the CM root setting iirc. Just FYI

Thank you very much,
I got excited for few minutes, then I followed the instructions link, and saw that big red banner of warning saying only MDL and MDB can use it.
And I am on OC3 (5.0.1) so I guess I'm out of luck!

Lag after root

Hey guys,
Great site. I have the lag problem with my S7 edge after root. Downloaded fix file from link in other in (Rooting Problem). Not sure what to do now. Do I flash zip with Flashfire? Leave it in the zip state? I realize this is elementary to most, just been a very long time for me. Hated to ask the question again. Wouldn't let me ask it in the thread I mention.
Never mind, figured it out. Thanks for the 37 views without advice.
Well what file did you download and did you use flashfire to install? I don't have root just curious

There's a file on the Verizon forum that helps most if not all the issues with root. Just flash it once and you're good to go. OP just doesn't understand people here aren't obligated to help him, self entitled privilege at it's best.

Sorry guy. You are right. I should of explained. I followed directions from this youtube video ( https://www.youtube.com/watch?v=Kqb-p2JO5I4 ). Worked , but was lagging and wifi issues. Came here, found and flashed with Flashfire., the wifi fix file , which I can't seem to find here now. Everything worked great. Until next morning it was stucked on AT&T logo. Only could get it into download mod. Had to do a factory rest. Want to youtube to look for a different way to root. Found this ( https://www.youtube.com/watch?v=QcFEcycZZnU ) followed directions and seem to work great right now. But time will tell. Sorry for the rushed details, busy day. Thanks.
Update. Yesterday got stucked on AT&T logo AGAIN. I decided the heck with this root, 4th time I had to set phone up from start. I did a factory reset. Set my phone back up. Lost my root according to Root Checker. But I am getting security warning, and when it reboots. It still shows custom and unlocked. Any ideals? As so, I tried to do the AT&T update, but it fails.
If it is showing custom & unlocked, you might have a custom recovery and/or unlocked bootloader. Just got the S7 edge, so I haven't really messed around with the internals yet (or anything dealing with rooting or unrooting), but that's usually what that means in my experience. The fix is usually an odin flash to the stock image, but as I said, I haven't really gotten too involved with it yet. A factory reset will set the system back to stock, but I don't think it does anything with the other partitions. Good luck and if I can find anything out that might help, I'll come back by.
So far as the update, do you have all the prerequisite stock bloatware installed? There are apps that are required for an update to work. If you uninstalled any it will freeze you out of getting updates.
And my signature is so out of date it is funny.

Trying to root, stuck at the first hurdle

Hi guys
I have a spare phone now my son upgraded, the S5 SM-G901F. I thought it wound be fun to install another software, possibly more up to date. So I first set out to root it but I haven't played around much with this sort of thing for long while.
I googled and found it seemed to be Odin to use so I downloaded 3.10. Also downloaded cf root. I went into download mode and when I plugged it in, the light in Odin lit up showing successfully connected. When I added the cf file and clicked start it went through some steps but stuck at Recovery. Img and wouldn't progress further.
I tried multiple times, tried a different cable and USB port and also Odin 3.07 and a different cf file even though I think it was the same one but from a different site. All no better.
Originally I bought it a few years back, used from a colleague. I think it was a carrier phone, EE iirc, and I had to get a code to unlock the SIM to use with mine. Maybe that also means it's software is locked?
Any help much appreciated
Thanks, marc
No one guys?

well to be honest, i would need to spend some time, "Googling" your model .... . I believe , your S5 is a Dev phone, meaning, it was not set up for any carrier, just for running demo's and such. IF this is true, I have no true answer for you.
Odin yes, you need that, that is true! (Believe 3.07, 3.09 and 3.10 work the best for these phones. Had tried a very newer version, several month back, and it did not do the job.. something like 3.14 or 16)
I recommend going to Sam Mobile, and run your model # through them. They will give you all the info about your model and possibly the latest firmware for it.
Sorry that I can not give you all that you are needing. I just don't know a ton about those S5 Plus models. (( I had to even look 'em up too) the plus has a slight better chip was well as graphics, but again, I dont know of any that actually work on a modern carrier like sprint, Verizon, T-Mobile , etc.)
Thanks for the reply mate.
It definitely isn't a Dev phone, my colleague definitely had it on contact from a carrier initially.
I hadn't actually realised or noticed it being a Plus model as some sites mention the Plus and some don't.
Any other help from anyone appreciated

OK, Was only going off your model # you had given.
Did check... Odin and a good copy of CF auto root... That should be that.
Then of course, get away from a really old non sucure os (6.01 MM was their last made) .
Other than those 2 pieces, you should be good to root
Not pushing, or anything but LineageOS is rather good and does run well on these!
Plus, get a monthly security injection!

That's the problem as i mentioned in the first post, I've tried with odin and cf root and it doesn't work. That's why i posted on here. I wondered whether the phone was locked to the carrier.

Well, I would have to say NOPE!
Well only trying to keep your Q, on the top, so folks that might know, could help!
BTW, when I looked your model up, totally different CPU and GPU, which might need a different CF auto root zip, or a different one to actually work... Since hardware is different.
Just guessing on that, but, could be wrong. Rather busy at the moment, but will look up your specs again, and see if I find something for ya.
Mean time, Hopefully someone could chime in and point you towards the correct path to take...
OH
Q- What sort Recovery do you currently have? (Stock or custom (e.g. TWRP))
Might want to check for one for your phone.
I would actually start with TWRP, see what they have for ya.
( Will need Odin for this! BUT, once you have a Recovery in/on the phone, then you could use Magisk to root ot try CF and see 8f that works for you (I use Majisk) Plus add in the fact that you should make a Back up, of your current system! In case of issues, you can always jump back to Stock. )

Cheers mate. So, some progression.
Firstly i didn't have a custom recovery or root. I was getting stopped at the first hurdle.
So, i figured it had something to do with it using a carrier firmware, EE, in the UK. So i found a stock European firmware and successfully used odin to flash it. Then i flashed CF root and TWRP. All good.
So with new confidence i flashed Resurrection Remix Android 9. Although it seemed to have worked, each time i tried to complete set up, straight after imputting my gmail address, the screen was black. Not BSOD type though, if i pressed home it went back to the home screen to i just couldn't complete set up.
So i tried Lineage and that was a boot loop.
Not sure if part of the issue was Gapps but i was definitely using the correct version. ARM, Android 9, stock.
I gave up, reinstalled the stock Android marshmallow and rooted again and installed TWRP. that's where i am now.
Shame really as i fancied a more up to date OS.
Thanks, Marc

Wait, isn't what you were wanting?
Well at least you now have a Recovery installed! Now, with that of course you can now make a back up of your stock!!!
( other words,.. MAKE A BACK UP! That way, you only have to wipe the system, data, cache and BAM, in the Flash of zip, your back at square one...)
OK, not sure if you picked up a new info about LineageOS, across the pond....
But
They ran into some issues, (soon and hopefully sooner, it will be fixed). Now, after that, they will be dropping LineageOS 17.1 Official!! Yes, for Galaxy S5 too
So, keep an eye out for that, cause am in same Boat, waiting for the Official release.
( personal, I run LineageOS, Magisk (Root and some goodies.. Unfortunately I do tend to add Ggogle, but like Pico, nothing larger. Do flash a kernel also. That said, rather stable, and most everything works) at least for me.... Just waiting for Official 17.1 to roll out! (like just about anyone left that has these phones...)
