[Q] Would like to go back to stock - Galaxy S 5 Q&A, Help & Troubleshooting

Hi guys, ive recently just brought a S5 (Model number SM-G900F, android version 4.42) second hand as an upgrade from my S3.
The gentleman that i brought it from said that it used to be rooted but he has unrooted it for me. What he has actually done is just do a factory reset and it is still rooted (i think!). When i so in to super su to uninstall i get the error:
"There is no SU binary installed and super su cannot install it. This is a problem!
If you just upgraded to android 4.3 , you need to manually re-root - consult the relevant forums for your device"
Im an IT manager so im alright with pcs but im a complete amateur when it comes to phones!
Please can some body give me some advice or instructions to either install the binarys (if possible) or get the phone back to stock.
Many thanks guys (or girls!)

Download the firmware from sammobile and flash it with odin and your phone is 100% stock.

[Q] Root and Firmware Upgrade?

So I'm new to Samsung (switched from HTC One to Nexus 5 (2013) to Galaxy S5 today). I used Chainfire's Odin tool to root (was easy enough), but now I'm getting a notification telling me there is an update, which because my phone is "modified" I can't run. I downloaded the Kies3 application and this is the info I'm getting:
Current firmware version : PDA:NC9 / CSC:NC6 / PHONE:NC9 (DBT)
Latest firmware version : PDA:NCE / CSC:NC7 / PHONE:NCE (DBT)
Can I update or do I run the risk of bricking? Or will I just lose root? Will the root tool work after this upgrade? Anyone have any ideas?
Thanks
A guy on a T-Mobile S5 subforum says he took the update and then rooted with Chainfire afterwards.
He was not rooted prior to the update though.
did it work?
because i had a problem with it

I finally bit the bullet and just did it, update went fine using Kies and then I re-rooted and installed custom recovery...everything seems fine. The only thing that blows my mind is the bloatware on this monster..."Android optimizing....429 apps" !!!

[Q] How to find information about bootloader?

*Foreword*: I googled now about 1 hour and did not find anything concerning my problem.
Hi guys,
since I just decided to upgrade to KitKat, I'm in need of a new bootloader.
Problem is, Odin is refusing to work.
It says that everything went fine and all, but after booting some system information apps still tell me I'm on an old bootloader.
My thoughts are that I maybe have a locked bootloader installed so I can't install a new one. Where can I find out whether that's the case or not? I already tried various USSD codes and stuff, but they all seem to be outdated.
Also, why are there different opinions here on xda how to flash a bootloader?
On guide says: "Flash it under 'Bootloader' in Odin".
Another one says: "Flash it under 'PDA' in Odin". As you may guess, I'm really confused right now.
My current specs:
i9505
XXUDMH5 Bootloader
XXAUEML6 System
Odin 307 running as admininstrator on Win 8.1 Pro
Any help will be greatly appreciated!
Thanks in advance guys!

Just flash the latest stock rom. That will automatically install the latest bootloader.

Samsung S5 - Lollipop - can i downgrade back to KitKat

Hi Guys,
I stupidly got excited and installed the official Lollipop (S5 on THREE UK network) update when i was notified.
BUT...
I want to go back to KitKat as i preferred it (i wont go into reasons why)
Is there a downgrade path for me, either officially or unofficially?> I dont think there is at the moment.
Thanks guys!
Yep, this forum is literally packed with instructions on how to do it, a simple search will bring up what you need
hi thanks, i thought with the new protected bootloader i didnt think it possible.
this is what i read:
Note: The G900FXXU1BNL9 Android 5.0 Lollipop update comes with a protected bootloader it is clearly emphasize that the “SE for Android Status – Enforcing” that might cause issues when you try to downgrade to the old software updates. This also applies if you are planning into rooting and installs any custom recovery and any unsigned firmware once you are on Android 5.0 Lollipop , so please be aware with that.

Yesterday I tried out AllianceROM 6.0 and a few hours ago I went back to 4.4.2 'cause I liked it better than Lollipop. Here's what I did :
1. Enter Download Mode and flash STOCK 4.4.2 KitKat firmware in Odin (I used 3.10.6) and let it start booting.
2. It won't boot, this is normal (I panicked when this happened though ).
3. Go to recovery and factory reset/wipe data your phone.
4. Now hit reboot in recovery and your phone will boot up again (YAY :sun.
5. OPTIONAL : If you've made a nandroid backup before going to 5.0 you can now flash TWRP and restore it over your STOCK 4.4.2 KitKat firmware.
Hope I helped Let me know if it works out for you!
SUCCESS!!!
All sorted.
The hardest part was finding a link to the rom. sammobile kept giving me a gateway 502 error.
im now back to kitkat, AND no THREE UK rubbish.

How to unroot to stock firmware (SM-900F)

I posted yesterday about rooting and everything worked fine courtesy to you wonderful people but my touchscreen is messed up and I need to get in contact with the seller on ebay to get it replaced.
I need to get it back to stock firmware with all the bloat as I pretty much deleted it all thinking my phone would work fine. I don't want any hiccups with the seller saying it was my fault blah blah..
I'm downloading the stock firmware from SamMobile for my device currently, but need a (n00b-friendly) guide so it goes smoothly with no troubles.
Thanks

It's pretty easy , here is the steps to follow :
1. Download the firmware.
2. Download and install samsung drivers.
3. Download Odin 3.10.7.
4. Extract the rom , you will get a 2.5 gb .tar file.
5. Boot your phone in download mode and plug it to your PC.
6. You should get a blue box in odin , click on AP , choose the .tar file , click on start , wait.
7. Done

Help with a troubled Tab 4 7.0! (Downgrade & QA)

Hi community I just need help to figure out what to do with my Tab 4 7.0 the history begins this way:
I get this Tablet already used not brand new it looked to have Android Lollipop 5.1.1 when I got it and didn't appear suspicious and lend it to one of my kids, the problem begins after some time the Tablet didn't connect to the Play Store anymore proly because my kids was trying to root it via KingoRoot or other apps to mess with some games, so after that I decided to solve the problem doing a Hard Reset but it didn't work, the tablet still can't connect to the PlayStore via RH-01 error message.
So I decided to flash it with the official stockl rom from Samsung, my BIG surprise is that this Tablet never get Lollipop 5.1.1 it didn't ever get Lollipop at all accordingly to this thread: https://forum.xda-developers.com/tab-4/general/links-galaxy-tab-4-official-lollipop-5-t3102844
Because my tablet is the SM-T230NU (the model accordingly to the box is SM-T230NYKAXAR) model and that model never gets LL, so I figure it out this was a modified rom? Even in the Info about the device over settings it says the model of the device i "Nexus 5" instead of Tab 4 or whatever Samsung call this device but not Nexus 5 that is a phone from LG.
So I stopped here, because I've heard it can be dangerous to Downgrade Android versions? If not what should I do? Use Odin3 and flash the rom mentioned in this thread: https://forum.xda-developers.com/tab-4/general/links-stock-galaxy-tab-4-firmware-t3013128
For the T230NU USA variant? Hope u can advice me about what to do and give some tips because this will be my first flash on a device.
Thanks in advance! :laugh::good:
They probably flashed a custom rom with broken GAPPS, just restore with Odin and the official rom.

By restore u mean flash it with some of the roms provided in this link: https://forum.xda-developers.com/tab...mware-t3013128
So there's no problem if I have 5.1.1 right now and get down to 4.2 as is the official one?
