Hello,
as thread title says, I need some advice from professionals here for my new Galaxy S5.
Well it's not quite new (almost 1 year) but never rooted it or flashed it, so I still got OS (original system) by Samsung.
I am a pretty amateur on such stuff. First I need some advice what to do: Rec & Root or flash custom rom?
Followng things are important to me:
The System has to be stable and fast: no lags, no crashes, no errors (I do not expect 100% stability, since not even OS is 100% stable, but it has to be at least stable as OS or even a bit more)
I need features and nice widgets (Rom must also be afordable to other apps and widgets, I 'd prefer Samsung OS widget)
I need good quality on camera (preferred OS cam software and features)
Good signal and GPS (Good and fast GPS is a MUST!!, as I use often Navigon when I travel with my car)
Good video player and galery app (Preferred Samsung OS Galery App, but video player can also be different than Samsung OS Video Player if its working fine)
What I do not do with my phone:
I do not play games
I do not read e-books
I don't understand the purpose of KNOX! Do I need it really?
Here are some details of my Smartphone:
Model no: SM-G900F
Android version: 5.0
Modem version: G900FXXU1POJ1
Kernel version: 3.4.0-6364590
Build number: LRX21T.G900FXXU1POK5
Securitysoftware version: MDF v1.1 release 4 / VPN v1.4 Release 3
I would be greatful if someone could give an advice if it is worth to flash a custom rom and if yes what rom based in what moden and kernel versions or if a simple root with recovery install is enough?.
Thanks in advance
Regards
Hi @GordonSpace.......
Most of what you said in your post leads me to believe that there are many things about the stock OS that you are happy with. That being the case, the old adage 'if it ain't broke, don't fix it' comes to mind.....meaning (for now) you might as well stay with stock. If you start flashing CM custom roms (for example) you will lose that look and feel.
On to your question about Knox.....
In a nutshell, knox is based around an 'eFuse' which will trip or blow as soon as you modify your device. This eFuse CANNOT be reset. Samsung are, in some cases, denying warranty repairs on devices where knox has been tripped.
So basically, as soon as you flash CF Root or TWRP to gain root, your warranty is void (Samsung normally provide a 2 year warranty on their devices). Tripping knox will also prevent future 'over the air' updates. So even if you unrooted your device you would be stuck with the version of the OS that you have on your device. Finally, tripping knox will prevent your device from connecting to 'business enterprise secure' servers. So if you currently use your phone on your employers network, this will no longer be possible.
If you still want to go ahead and forget about knox, this is the easiest way to gain root......
Follow exactly....
1) deactivate 'Reactivation Lock' (can be found under Security in Settings).
2) copy SuperSU zip to your device.
3) boot into download mode.
4) Odin flash TWRP 2.8.7.0 (specifically this version).
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)
7) flash SuperSU zip.
8) boot device as normal.

When you have root access, you can get Titanium Backup from the playstore and freeze/delete the 'bloatware' that comes pre - installed on Samsung firmwares.
That will then give you the stability of the software designed for the phone coupled with the look and feel that you like, but without the resource hogging rubbish that most people with unrooted phones have to put up with......

Hello keithross and thank you for your response.
I use my smartphone only in private.
However it still has 11 months warranty by Samsung. Another Idea I had was to sell my Galaxy S5 as it is (OS and Knox) and buy another smartphone.
However what would be your recommendation for a new smartphone?
I was thinking about LG or HTC. But I'm not sure about to purchase a "famous" brand device or just a cheap one like Mobistel, Huawai and such.
What is a nice smartphone to have it root / flashed?
Regards
Kiri
I have about 9 months of warranty left on my phone....but I was able to root without tripping knox.....simply because I rooted before I allowed my phone to update to Lollipop (I rooted with Towelroot while running KitKat) then debloated, and customised the stock firmware.....so I have my phone as I want it, and still have knox intact.
The S5 will probably be my final Samsung smartphone, but as of this moment, I haven't given much thought as to what I'll replace it with. I'm half tempted to keep it beyond the end of it's warranty and start trying out custom roms at that point. It does everything I want it to do, so why would I need to replace it?
On the other hand, if i did replace it, I'd probably stay with one of the well known brand names.....The chances are that they'll have more dev support than the less popular makes of device....but I won't waste my money on any more flagship devices, I'll probably look at the 'upper midrange' devices as they'll (by that time) probably have similar specs to my current device (the way technology is currently advancing, they may even be superior to the S5)......

CyanogenMod
I decided to flash cyanogenmod snapshot
1. However I do not understand the difference between klte and kltedv rom (kltedv = vodafone. does that mean my provider has to be vodafone?)
2. TWRP or Cyanogen Recovery?
3. Do I need to install a diff Kernel version?
4. Anything I should take care about before I flash? (something special about Samsung drivers, kernel, odin etc...?)
Thx for your support.
1....In all honesty I can't answer having never flashed custom to my S5.
2....TWRP recovery over Cyanogen recovery....Every time. Cyanogen recovery is little better (if at all) than stock recovery.
3....flashing a different kernel isn't strictly speaking necessary....unless you want to be able to change processor clock speeds and voltage and apply various other specialist 'tweaks'.....
4....after rooting (but before flashing) make a backup of your EFS folder (critically important) it contains, amongst other things, your IMEI number. If this folder becomes corrupted, you're in a whole world of hurt....
Back up any personal data that you can't afford to lose....things like photos etc.
Make sure you have a copy of your current firmware available....If it all goes pear shaped, you'll possibly need it to recover your phone.
The version of Odin that has most compatibility with the S5 is v3.10.7 though other versions *should* work.
Get hold of and install the Samsung USB drivers on your pc....They come bundled with Kies available on Samsung's website. (If you install Kies, you will need to use task manager on your pc to kill the kies processes prior to flashing anything with Odin).
Use the usb cable that came with your phone when connecting it to your pc.
Make sure you've disabled your firewall and antivirus before attempting to use Odin.
If you need any more help just let me know by commenting below.....

Hey thanks mate. I rooted my device with CF autoroot via odin. I read that CM13 with Android 6 is as a stable version out now. Probably I am gonna flash it. However, I have a question with my current root of S5. Currently the wifi passwords are being save as an encrypted hex key in the wifi_supplicant.conf file. However I would like to use an app that saves and shows my wifi passwords, but unfortunately due to the encryption of S5 it's not a help for me. Any recommendations what can I do to save the real PW instead of the encrypted key?
Sorry fella....The tech aspects of your question have gone right over my head like an international Jumbo Jet....I have no idea what you're even asking about, let alone how to solve it for you. Your best bet would be to create a thread specifically for this question.....you will probably get more views for that thread than for this one.....sorry mate....

You should already know the passwords if they are your routers/APs
I don't know my passwords. The thing is, that sometimes we go to some cafés and such where I have saved the PW of the router, but sitting with friends some of them do not have it to connect with wifi. Thats why I am asking if there is a possibility to view the passwords I saved in my wifi connections (not as a hex key but the true passwords). Anyway.. thx for help. I guess thats Samsung OS. Hope it won't be with CM13 like this.
As the title implies, I've failed in my attempt to root my S7 Edge. I can access the custom download tool as well as the TWRP tool that I installed via Odin. However, I have no SD card and my attempts to use ADB have been unsuccessful. Right now I am looking for an option to reset my device to factory settings. I don't care about my previous data, as this is a relatively new phone. However, I believe my warranty is voided, and that is why I am posting here.
What are my options at this point? If it helps, a micro SD is arriving via Amazon tomorrow afternoon. Ultimately, I'd like to be able to install a custom ROM or root my existing Nougat that I started with (my original intention).
As for how the process may have failed, the tutorial I watched didn't seem to make it clear that I had to enable USB debugging. I enabled OEM Unlock, but not USB Debugging. Any help would be greatly appreciated. :good:
EDIT: Smart Switch does not support the device for emergency recovery. I really think I messed up my phone
EDIT 2: After suddenly disconnecting during the download process of a fresh firmware via sammobile, I restarted the device to reach an error screen telling me to use Smart Switch Emergency recovery. However, my device was not supported. Following a guide online, I clicked on the More tab at the top right corner of the Smart Switch program and chose "Emergency software recovery and initialization". I entered the relevant information for my device and the recovery process began (fingers crossed). After it has completed, I am now once again booting my factory firmware. I'll leave this post here because I couldn't find a similar post on the first couple pages of the forum or with the search function.
Now, can anyone direct me to a proper beginners' guide to rooting the S7 Edge? I'm fresh off of iOS, which I've used and been jailbreaking for the past nine years. I thought it would only slightly more complex, but I see due to the many different versions of the same device, rooting can be quite tricky.
Edit 3: New question which I can't find the answer to anywhere... Do you need an SD card to root? I'm resetting my phone for the second time now. Got a boot loop after using ADB sideloader to install supersu.
Where did you get the stock firmware? I have the unlocked sm-g935u... made an unbelievable stupid mistake and my three day old s7 edge is partly functional (only bare essentials), but whatever I did before wasn't wiped when I did a factory wipe so my phone thinks it's rooted even though it most certainly is not. (And many features and apps won't work bc of it. )
I can't find anything useful about theNougat firmware. I'm really desperate. My company bought me this and i broke it within a week. :'(
so I am a mom of 3 including an infant and exhausted trying to figure this out. Trying not to clog the board opening a new thread. Long story short- I want to use an app that the developer has not been able to fix the errors with it when using Nougat on an S7. They suggested I upgrade to Oreo or Pie to fix this. I have an unlocked phone purchased outright on eBay and use Total Wireless. So there will be no one to assist me in this. I'm fairly tech savvy so I looked on YouTube about rooting and upgrading with a custom ROM.
I watched these videos:
sorry new cannot post
So easily I enabled developer options and OEM unlock and USB debugging. Downloaded Odin and Magisk and no verity and Gapps and lineage 16.0 (from Ivan Meler) and twrp with the twrp-3.3.1-0-heroqltechn.img.tar file which I determined is which one I needed.
Odin will not flash TWRP (one of the first steps). Fails every time. It does start blue and I did download and install the latest Samsung drivers package just to be sure.
Then I found it was probably because I had a locked bootloader. So, I used this tut and that did successfully download to my phone via Odin. But TWRP still will not "flash" to the phone.
Now, my fingerprint sensor says "The fingerprint sensor is not responding, please try again later". and my phone has a security notice stating "unauthorized actions have been detected. Restart your phone and undo any unauthorized changes". So I am thinking that I did successfully unlock the bootloader? But TWRP still will not flash.
I considered using oneclickroot.com but it's $40, phone only worth about $100, and my husband is convinced they're going to steal info from my computer and phone in the process (even thought they're XDA endorsed). They also told me they can only give me Oreo not Pie.
I have downloaded and used SuperBackup. Also all my photos are auto backed up to Google and my contacts and calendar are too. So I don't think it's a huge deal if I lose everything. Even if I brick it I can get another. Reinstalling and relogging into all my apps will be a pain but whatever. I have a password app that can be logged into from the web.
Also my camera has been getting buggy and not opening and having to be restarted and in general the phone is just getting glitchy, so I was hoping an upgrade might help.
All the info I have:
Model G930V Ver 7.0
Baseband G930VVRS4BQC9
Build NRD0M.G930VVRS4BQC9
Knox 2.7.1
When I enter developer mode:
Odin Mode (High Speed)
Product name: SM-G930V
Current Binary: Samsung Official
System Status: Custom
FAP lock: Off
Qualcomm secureboot: enable
AP SWREV B4(2, 1, 1, 1, 1) K1 S3
Secure Download: enable
My startup screen where it says Galaxy S7 powered by Android also now has an unlocked lock icon and says "custom" underneath.
Should I just figure out how to "undo" what I did and leave it alone? I'd really like to use the eMeals app and I'd really like to not buy a new phone.
You can't flash twrp on a US branded snapdragon s7... only on exynos versions of the phones...however...there are ways to obtain root and there are ways of using twrp temporarily while running programs on your computer...it is very perplexed and I can't easily explain it but just read through the threads and google root and twrp xda snapdragon s7 and read up on it...or better yet look into the roms thread...jrkruse has some roms with temporary twrp and easy root...u will never have true custom roms or magisk on that phone but has got some awesome stock base roms and ways of doing things where you wont really miss custom roms
---------- Post added at 12:06 AM ---------- Previous post was at 12:03 AM ----------
To get back to normal use Odin and flash the ap, bl, cp, and Csc files via the instructions...u have to read up on it...google Odin s7 back to stock
Hello Everybody,
I am an old iPhone user, who just switched to Samsung Galaxy S8.
I am used to simple Jailbreak one touch jailbreak, but this android is a WHOLE new thing for me.
I would like to root my phone with a ROM, which do not have KNOX and found WCKD on YouTube, which makes awesome guides regarding S8.
Problem is now, that I follow his guide "HOW TO INSTALL TWRP & MAGISK ROOT on Samsung Galaxy S8/S8+ | UPDATE 2"
and everything went smooth until I needed to reboot my phone.
Now my phone stays on the Booting Screen showing Samsung Galaxy S8 and I cannot get into my phone.
I then found another guide by WCKD "Galaxy S8/S8+ Odin FAIL, BOOTLOOP, BOOTLOADER FIX!"
But this time it did not go smooth, every time I go to download mode, then press Start in Odin and then directly hold down volume down+Bixi+power bottom it will not success, so I am failing all the time, same thing happen for a lot of other people, since they had commented his video. For some it worked but for many they have same issue as me.
What will be my next step here?
If I hold down Volume up + Bixi + Power bottom nothing is happening
If I hold down Volume down + Bixi + Power bottom I can come into "Downloading"
I really hope, someone can tell me what to do next, so I can use my "New" Samsung phone.
Update
I managed to fix the last phase before installing a new ROM without KNOX.
Would my next step be to download a ROM without KNOX, and the install it through TWRP?

1. In Odin under options untick auto reboot. It will prevent the phone from reboot when flashing is completed. Reboot manually.
2. For custom rom search

How important is it to flash the Kernel?
I did flash my phone with AMBASADII ROM FOR S8 & S8+ [ODEX] [AQH3] [v1.4]
https://forum.android.com.pl/topic/322837-rom-ambasadii-rom-for-s8-s8-odex-aqh3-v14/
It states fully knox removed! (rom not support: samsung pay, samsung pass and secure folder)
● Support models: SM-G95xF and SM-G95xFD
But after I flash the ROM and it got installed my phone still have KNOX 0x0 instead of 0x1 which makes no sense since I have TWRP installed on the phone.
Is it possible that ex. this ROM is so old, that it can not remove the KNOX security from a Samsung Phone?
Would love to get some recommendations about which ROM I could flash with so the KNOX 100% will be deleted.
Also would be happy if someone could explain me how important it is to flash the Kernel, and what I should look for.
Cheers!
Update 3
Today I flashed my Phone with [ROM] [PIE 9.0] AMBASADII ROM FOR S8/S8+ [STABLE] [ODEX] [DSD3] [v9.0]
in the Description it clearly states that KNOX is removed.
Knox and FOTA removed! (rom not support: samsung pay, samsung pass and secure folder)
https://sites.google.com/view/ambasadiidev/strona-główna/ambasadii-rom-for-s8s8
But it is not, when I go to Phone info I see this information.
Version of Knox
Knox 3.2.1
Knox API Level 27
TIMA No Poicy Version
Am I doing something wrong when I am flashing the ROM? I am using TWRP to "Install" The ROM.
Do I need to do something after I flashed the ROM? Maybe some kind of Kernel?
Thanks in advance.
Hello, I am trying to unbrand my LTE Tab A from Sprint SM-T517P by flashing another CSC, or flashing another PIT on a patched version of ODIN with no success.
Can anyone tell me how to do it properly? I have read about Chimera, and Samkey, but they are too expensive, and I worry about bricking my LTE tablet (do not want to root, and there is no root anyway).
Any help?
I made little progress. I think I got the latest correct firmware for it downloaded, but it didn't want to flash with a patched Odin, but it did flash successfully with a non patched version of Odin.
After that, I tried flashing a CSC from another firmware of an LTE that is unbranded (SM-T515), but I always get a SECURE CHECK FAIL PIT error.
Does that mean I need to unlock the bootloader? Is that even possible? I wonder how Chimera, or Samkey is able to change CSC thru just software, but they are too expensive for me
Any help?
I soft bricked the tablet by flashing the AP, CP, and CSC of the latest firmware of International unlocked model SM-T515... I was able to recover by flashing its latest firmware for SM-T517P.
I worry about hard bricking it, but after so many tries with different things, I feel so close
Flashing only the CSC of any other firmware hasn't worked so far, and flashing anything other than Android 10 Q doesn't work either, even after unlocking bootloader.
I have NOT flashed bootloader of another firmware yet, super worried I may hard brick it if I flash another BL even after unlocking its bootloader.
hmmm i dont think there are many modifying the sm-t517p. i also own one of those on t mobile . i wanted to add twrp and root ....i cant seem to find any version made for it...so onto the magisk played with thatfor a couple days and locked it up a few times ...i think for now ill be okay with no modding ..idk why im compelled to screw p a perfectly fine working tab-phone. i did however just see that kali linux can be run on it without messing the os up..maybe ill ry that next... why did you want to modify yours? so you could switch carriers im guessing? luckily for me t-mobile took over sprint........just curious
bootloader unlock...
Unlocking BootloaderUnlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode

Hi, I also have a sm-t517p and have searching to find twrp and root. So you had no luck at all? No root even with magisk?
