My Galaxy S4 just decided to show wavy lines on the screen instead of turning on - as far as I can tell the screen and digitiser are no longer working.
**I CANNOT SEE OR DO ANYTHING ON THE SCREEN**
I have a 4.2.2 i9505 UAMDE -Stock Rom- that is rooted.
I have never flashed any other firmware to it - just rooted it.
I have Kies access and backed up my phone. Kies prompted for a firmware upgrade when I plugged in the phone.
I want to return it to stock/unroot etc so Samsung will warranty the phone without fuss (it was not dropped, just stopped working).
Some questions:
Most important:
1. Is it possible to get the phone to a state that will be warranty-ready without having a screen?
2. Do I need to Triangle away if all I have done is rooted? If so, can I do this without a working screen?
3. What is the best way to return to stock? ODIN or should I just let Kies update to latest firmware? (If either will it be enough to satisfy the first question)
4. If Kies does the update will I need access to the screen to complete it?
Thanks in advance!
1. You can flash same firmware with ODin. It will delete root access, but app will stay, so you have to uninstall it through https://play.google.com/store
2. You don't need to, unless you've made a root through Oding flash?
3. Odin
4. No, but it will udpate it to 4.3 with KNOX?

Thanks for the quick reply.
1. not sure which 'app will stay' you mean?
2. Actually I cannot remember how I rooted - I will have to look this up again. Something tells me cf-autoroot and maybe ODIN... All I can remember it that I still have stock ROM just with root.
4. Agree that this might not be the best idea as I am trying to stay away from KNOX but I wonder if Samsung will automatically update to the latest ROM as part of the fix?
Kies is currently sitting on backing up "preparing" for ages and ages... hope it works in the end.
Looking back I suspect I used CF-autoroot which probably mean my counter has gone up.
Any way of resetting this without a screen?
I've managed to get some screen control using adb, screencast and teamviewer.
Triangle away says:
Counter: 0
Binary: Official
System: Official
I suspect the Official comes from the fact I was running Wanam Xposed and spoofing official.
One last question -
Given all that information I should just be able to flash
4.2.2 UAMDE Stock rom from sammobile with odin
and everything will be warranty-ready?
(will this wipe all my data and programs as well? - something I WANT to happen)
It will not wipe it. On the older devices like S3, there was a special ROM for cleaning purposes with PIT file, that was repartitioning your memory. Maybe there is something like that for S4?
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.
Hello all,
This is my first Samsung device, the Galaxy S7 Edge Dual sim (SM-G935FD) bought from UAE.
I used to install TWRP and root every android phone I had before, so I am still not sure whether to root this one. I already have the files required for rooting, but I noticed that there are 2 ways of rooting:
1. Using Odin to install TWRP and then from there install SuperSU.
2. CF-Auto-Root.
What is/are the difference(s) in both methods?
My other question is: I read that rooting will trip Knox, and there is NO WAY to get it back to normal even flashing the original ROM. Is that the case?
One last thing, I am now stuck in the download mode (turned off the phone, pressed "Volume down", "Home" and "Power"), I did that just to check the info on the top left (model and warranty void...) but I cannot seem to restart the phone even by pressing the power button for more than 20 seconds, how can I turn the phone off then back on?
Thank you
*****EDIT*****
Regarding my last question (stuck in Download mode), pressing the same combination got me back to start the phone normally
Cf-AutoRoot will root your phone but then you will have to put your recovery on also usually flashed with Odin anyway or an app if it's working for the Galaxy S7... Twrp plus superuser will root and you'll have the recovery installed.... They both will trip your official (0x0) knox and make it (0x1) custom.... You can always go back to stock rom and get OTA updates but your knox will remain at 0x1......this is supposed to void the warranty but depending on where you live it won't make a difference.... Also if you want to flash roms and mods and kernels just use the twrp method and if you just want root and to be able to use root permission apps use the Cf-AutoRoot.... As of right now I haven't rooted because there aren't to many Roms available... I'm sure I will cause I miss titanium backup and the ability to get rid of all the bloat ware (especially Facebook & Microsoft ****).... The phone runs great without root and battery is excellent.... The last reason I was waiting was Samsung pay won't work with tripped Knox counter.... I live in the US but have the international 935F... So it doesn't look like this variant will support Pay anytime soon.... Probably gonna root when development picks up a little....
*edit*... Always have a stock rom just in case saved to your computer just in case... That would of saved me lots of freak outs and headaches years ago... Now it's the first thing I do before Rooting or flashing anything to my phone

Thank you for the detailed reply.
I made a research yesterday on Knox (as I said, this is my first Samsung device), and I just wanted to make sure that I understood things properly.
So now after reading, tripping Knox will disable Samsung Pay (I do not have it in my country) so that is not going to make any difference. But, what about paying using the fingerprint sensor in Google Play, will it stop working if Knox is tripped? I also use the fingerprint sensor to login to my mobile banking app (instead of typing the password every time I want to login), will that stop too? I guess not but again just to be sure.
Thanks a lot once again.
I know when I rooted my S6 all the fingerprint stuff still worked so I dont think it will make a difference... Im not sure with the S7 edge but I would think it would still work cause all of those require a typed password before you use your fingerprint(1st setup only) Then use your fingerprint there after... .. Doesn't have anything to do with Knox
Galaxy S7 edge
yep, it all still works. just Samsung pay & private mode.
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
I just got an SM-G975F/DS ~ seems like the Taiwan version.
My current issues:
Can't disable emergency alerts!!!
Can't clear voicemail notification from tray. Infuriating.
No hosts file override (need this for app development & Adaway)
Samsung bloatware
I don't give a f*ck about Knox or Samsung Pay but I like the stock camera so I have a few questions about the root process.
First it seems like this is the process just to have root in with Stock ROM. Please correct me if I'm wrong.
For randoms reading this: THIS WILL NOT WORK ON USA Snapdragon VERSION
Enable OEM Unlock from developer menu.
Boot into download mode (Plug in PC connected USB cable while holding Bixsby Button + Vol Down)
Unlock bootloader by pressing volume up and confirming (not actually unlocked yet due to Samsung trickery)
Quick setup OS with Internet connectivity knowing it's gonna be wiped again.
At this point Samsung's Vaultkeeper service should detect OEM unlock and finally actually unlock the bootloader.
Install Magisk with this guide.
So it seems like this process would patch just the AP partition with Odin while keeping the ROM and Recovery stock.
So here's the questions.
If I continue to run stock ROM with Magisk with this method any official OTA updates must be done manually or I risk bricking the device?
If I install TWRP and try out some roms and don't like them can I go back to stock?
Is it possible to flash stock rom WITHOUT Magisk after doing all this?
I plan on writing some simple guides on this when I'm done since the current ones are a bit confusing so I would appreciate some clear and concise answers the the above questions.
Thanks all!
