Hi all, sorry for asking what has no doubt been asked before but I've been trawling through the forum and I'm struggling to find out what I want I know. I have an S6 Edge which I got from Carphonewarehouse on Vodafone (wish I'd stuck with Three) and I wanted to get the WIFI calling working because I'm often in areas where there is no signal (again, wish I'd stuck with Three!).
The phone doesn't have the WIFI calling option on it so from what I can gather, to get this working, I'll need to flash it with the Vodafone rom. I think I can just about bumble through this process with Odin but I can't work out if I'm going to lose functionality by doing it (specifically losing access to banking apps, losing fingerprint scanner, tripping Knox counter). I don't think I fully understand rooting and flashing and if they are one and the same thing or two separate things (I'm not interested in unlocking anything and tweaking registry type things, I literally just want the phone as it is now but with WIFI calling).
I'm a bit out of my depth on this tbh and from what I can see, if I trip Knox it can't be untripped. Can someone help point me in the right direction pretty please.
Thanks for any help.
Ok tripping knox will void samsung warrenty and samsung pay wont work, some banking apps may not work depends might have to google around and see if your will. Finger print scanner and everything else will work fine.
To flash and root are two different things. Rooting is to gain admin access on the software.
Flashing is done threw odin on a pc to change software, bootloaders, modems, recoverys things like that.
If u decide to flash a custom recovey like TWRP this can also do some of the things odin can the files are just in zip instead of tar for odin.
If ur looking to go to a new stock firmware then no need to root.
First ull have to make sure ur bootloader isnt locked cuz if it is i dont think you can flash other stock roms. I cant be totaly sure as mine is unlocked maybe someone else can chip in here.
If ur looking for wifi calling are there 3rd party apps in the play store that can do this for u?
Your also right about tripping knox once thats done no going back.
If all you want to do is flash the Vodafone firmware with odin, you will be fine and it will not trip knox, there are guides on here on how to do it. The phone was purchased from Carphonewarehouse like my own so the bootloader should be unlocked. Just make sure you read the guides fully and you should be good x

Just to add my first s6 edge was purchased from Ebay and was 02 branded and i flashed it to generic using Odin knox was not tripped, because its a stock firmware it will not trip knox
Thanks xstokerx and jadaress1, I really appreciate you both responding. Jadaress1, you are spot on in so much as I just want to put the standard Vodafone firmware on which, as I understand it, incorporates an extra question in the Phone Settings to be able to switch WIFI calling on/off. I will have a good read of the guides on how to do it tonight and take the plunge, wish me luck !! Thanks again.
Well .... last night was interesting ... EPIC FAIL!
I downloaded the most recent UK Vodafone Rom for my model from Sammobile then set about putting the phone in download mode. All seemed fine, Odin 3 loaded up the Rom fine and picked up the Com for the phone so I hit "Start" then, just as it was about complete everything (literally about 1/2 mm away from complete on the Odin and Phone status bars) it came up "FAIL".
I waited, waited some more, nothing! I tried to flash it again, another FAIL. I downloaded the 2nd latest Vodafone Rom (I resorted to paying for the fast download option on Sammobile because I was in a state of panic ) and tried flashing that, still a FAIL. I then took the executive decision to disconnect the phone and try to reboot it (I knew this was probably stupid but had run out of options) and then got an error message saying I needed to do an emergency recovery. I tried to load up Smart Switch and was told the device was not supported.
At this point I'd lost the will and resigned myself to the fact I was going to have to buy a new phone!! ... finally, after several hours of trying various things, I found a solution which was to extract the hidden.img file from the Rom and flash that individual file to the phone and much to my relief, the phone started working again but ... still on the old software (and *#1234# no longer works, I get an error message if I try to do that now).
All in all, this was not the smoothest software flash So ... does anyone know what was likely to have caused the flash to fail both times? I'm contemplating trying it again if I can find out why if failed and fix the problem (I must be a glutton for punishment!!)
Thanks in advance for any help, all gratefully received
I'm guessing as there has been no replies that there is no obvious reason why flashing the Vodafone rom failed. I'm a bit reluctant to give it another go given that I very nearly didn't get the phone working again after my previous attempt so I guess I will have to live without wifi calling for now

I've had big issues with my WiFi not working ("Error" message) after rooting.
Not sure if it was something to do with a PIT file or not.
I've spent considerable time installing CF Roots and ROMs and now I can think of nothing else to do but return the phone.
The phone was from Three and was network locked. I removed the network lock and flashed it from KE2. I don't know whether putting the network lock on it again is simple?
Can anyone tell me how I prepare the phone, so that it returns with the same firmware as stock and how to make sure the counter does not show that any flashing has occurred to void the warranty?
Appreciate your help. Ideally someone will have a full 3 backup online. If possible, could you give links to any examples, thank you.
Install original 3 firmware >> either your saved original or from branded roms post dev section .
Reset custom rom counter to zero if needed .
Binary rom counter post dev section .
Pit file should not have cased a problem but its not used unless instructs say to use it .

Thanks for the reply.
I've flashed the stock 3 firmware/kernel but it's still NOT network locked. I can s put my O2 card in the phone and it works. Therefore I presume that there must be more than just these flashings required.
Also I've looked on the dev thread and it appears that you have to buy a jig to reset the counter. I have no problem buying one but I'm very much pushed for time with the retailers return date arriving before a potential jig could. Is there a Odin flash that can be done to remove the counter?
Regards
Once a GSM phone is sim unlocked to work on any carrier, it can never be relocked. Once sim unlocked its permanently unlocked for all phones.
Would it matter even if it was unlocked? Im sure they wouldent be bothered. Good Luck OP

Ok, so I'm kinda already at stock. When I first got my SGS2, I rooted it but didn't put a custom ROM on. I was happy with this arrangement. It's been so long now though, that I've forgotten what I did and how to get it back to how it was when i bought it.
I have taken a screenshot of my info page: Here
I've spent all evening trying to get it back to untouched status - I've managed to unroot it and flash the stock kernel (even though the kernel info in the screenshot still mentions root for some reason). This doesn't seem to be enough though - it's still failing to install an OTA or kies update.
I'm going to be passing this phone on once the SGS3 comes out, so it's vital that it's back to square one and able to handle OTA updates.
I'd really appreciate some guidance here, I've been out of the tinkering game for far too long!
I don't see anything out of the ordinary on your screenshot. Have you ever changed CSC? Also, make sure you disable USB debugging if you ever enabled it.
Try * HERE * for the official O2 UK ROMs, with the latest being XWLP3. These will wipe and unroot your phone.
Intratech has put a link at the top on the procedure you need to follow.
Don't worry what the kernel says. When I first got mine it used to say root and dell and it wasn't a dell or rooted.
What's CSC? I've turned usb debugging off btw.
I've tried the OTAs and they download, but when it comes to installing it stops at 14% for a moment, moves up to 19% then reboots and gives me a failed update message.
I did wonder if i changed the recovery but I'm not sure how to tell - or how to change it back if I did. Would that cause problems?
I'll check out that o2 stuff, thanks. This phone was bought unlocked and unbranded though, will that matter?

A quick google would lead me to say that no, I didn't change CSC. I hope!

you have to reset the counter as well search forum for custom binary counter and usb jig
other than that you may try to flash an old firmware 2.3.5 and then reset counter;
the stock rom how did you obtain it? is it the right one for your phone's region? did you have another one?
i would recommend you use fusdownloader; get the right stock rom for your phone and flash then; i have successfully unrooted my old sgs II before I gave it away to my mum as a birthday present
I've always stayed at stock rom because I was happy with it. I think the only rom-related change might have been to update to 2.3.3. Pretty sure it was the correct region. I didn't need to wipe anyway.
Would wiping and flashing everything from scratch solve my problem? Rom, kernel, recovery etc. I could do that, but I'd wait until I was about to give the phone away. If there's a single package to flash in Odin that sets everything back to factory standard, that'd be perfect.

Oh and about the jig? If that's the only option that doesn't involve a full wipe, I'll just hold off until I wipe. I don't fancy buying a jig for one task.
This'll teach me for tinkering and then waiting a year to revert!

To me its as simple as flashing O2 firmware via Odin after a full wipe of phone via CWM recovery .
GB O2 was posted KDD and KE2
and ICS LP3 O2 is available and should be on Checkfus .
kernel says root has nothing at all to do with ROOTING or even a rooted phone its a build signature only .
OTA update is known to be poor for some sticking during the download .

Hello fellow XDA user
I have recently bought a the I9100 internation version and I am really pleased, however I do know the power of a ROM and how much it could improve or brick your phone.
However I came from the Galaxy S i9000, I never managed to recover the phone, so it would be recognized by kies, it did recognize my phone, but it said that 'Kies didn't support any upgrades for it'. Meaning if I would like to return it for garantee reasons, the shop or manufacturer will see I have been messing with my phone, which excludes my warranty.
Therefore I wonderd if there was a possibility to install roms or root your phone and unroot it, so kies would regonize it again.
Thanks alot and feel free to suggest any rom

yes there is a way cfroot to which will give you superuser access and also CWM recovery by then swapping back to stock kernel will unroot also if you using odin to flash this wil increase binary counter look for a app called triangle away this will reset the binary counter but only works on ics.
this is just basics to answer quickly your question please still search within the sgs2 forum sections most of all new users questions have been answered and there is many guides for new users to refer to in development sections prior to installing customs roms etc

I know about CF root .. but as I said before, I managed to restore the stock functionality of my Galaxy S, but I never managed to get support from Kies again. ('Kies doesn't support updates for your phone'). I don't know if the Galaxy S II method might diffrentiate from that .. but I do want to be on the safe side with my warranty and I don't want another bad to happen to my phone.
Quik Recap
1) Prepare Odin --> Go download Mode (Power + volume down + home button)
2) Flash Phone --> Odin --> Install CF Root Kernel
3) Mount Phone ---> USB --> Download Rom ---> Boot ClockWorkRecovery (Power + volume up + home button)
4) Enjoy Rom --> Enjoy Xda Power
5) How to Revert?, will kies regonize it and support it

Can someone please answer my post above, I really want to start modding, but I also want to be able to get back to an unrooted version with Kies support
Check out the links in my signature, especially the one about going back to stock. That should satisfy your request.
Long story short, reset your flash counter and flash stock rom. But make sure you READ
OK. The experience on here over the past 6 mths or so goes something like this. About 50% of people who go back to stock firmware for their region after using custom roms or stock firmware not for their region seem to be able to get OTA updates via Kies OK. For some reason(s), the other 50% or so of these people seem not to be able to get OTA updates to work despite flashing a full stock rom for their region (with correct CSC).
Why doesn't it seem to work for some people ? Who knows ? I don't think I've seen a single answer that could cover even a small majority of those cases.
Regardless, if you find you ever go back to stock with the intention of getting OTA firmware updates & they don't work, do what plenty of people on here do & flash them via Odin. Easy fixed.
The bottom line with warranties is this. The moment you start rooting your phone or flashing non-stock firmware on it, you should forget about/lose all expectations of warranty service/replacement should something go wrong with your phone. At the end of the day, you mess with your phone, why should Samsung/your telco foot the bill ?
Having said that, if you format everything, go back to stock & reset the flash counter, again, the experience on here is many people seem to get warranty service OK.
What you seem to be looking for is a 100% iron-clad guarantee.
There isn't any. If potentially borking your phone & having to pay to have it repaired/replaced yourself frightens you, best advice would be simply don't mess with it. Stay on stock. That's the only way you're getting 100% guarantees. If you've only ever been on stock/OTA updates & never rooted/flashed custom firmware and the phone borks, they pay to fix it.
Pretty simple really.
Hiya guys!
First post, so hello to everyone reading this
Ive got a Samsung Galaxy S3, and I did ask if it had been rooted or played with, and the guy said NO definitely NOT, but when the phones put into DOWNLOAD mode, it most definitely has had something done!
Count is on 1, ODIN is at the top, and CUSTOM is displayed in the last two fields I think, might not mean its rooted and I am new to these, but think it may have been
It was "OPENED TO UNLOCK ONLY" and was a T-Mobile UK Handset, I needed one that works with TESCO MOBILE and I did a swap with the guy next door to me for a broken iPhone 4s and to be honest I was sick of the Apple crap anyway!!!
So, my questions in no specific order are....
1) Is it rooted?
2) If I UNROOT it, will I lose the UNLOCKED to all networks that I need?
3) Is there a way to update the software on the phone if its rooted as I think I read somewhere that the firmware cannot be upgraded on a rooted phone?
4) How easy is it to install a new firmware?
For now, I think lol, thats it, so please any help appreciated!!
Cheers
Chris

The phone needs to be rooted in order to network-unlock.
So yes, at one point it was rooted.
However that does not mean it still is rooted, most probably the seller reverted it back to stock after rooting. Flashing stock does not increment the counter (since it's official) so it's quite possible.
[2]
No. Networl lock and other details are stored in the /efs/ folder which has nothing to do with the ROM and kernel.
[3]
You can upgrade a phone if it is rooted without further customizations. However you'll loose root during the process.
If [1] is true, you're on full stock anyway.
[4]
Depends. If you want to switch to another ROM, it's of course harder than upgrade within a given ROM (stock, Omega, CM9, ...)
But by all means hard does not mean impossible, it just takes some time and preparation.
Some afterthought: your seller should've just used the (free in XDA, paid in Play) TriangleAway app which resets the Download counter to 0.
I'd recommend resetting it if you're planning on staying on stock since it'll make warranty claims far easier or even possible. You'll need root tough to get it working.
Btw: network-unlocking a S3 means flashing CF-Root (rooted stock kernel), installing a free app, running that app, installing TriangleAway, running Triangleaway, flashing default ROM and factory-reset.
All-in-one that means less than half an hour, so I hope you haven't paid much extra for that feature.
I have solved this problem I think last night by updating to XXEMB1 on Kies last night - I have of course lost root for the moment but will get back to that later when I have more time
I have an international galaxy gt19300
It had begun to restart itself a few times a day and then would run for days with no issues
I eventually decided to root it when I found the new toolkit on here which seemed to work a treat
I now had superuser installaed titanium back up and ROM Toolboxand paid for pro versions of this and toolkit
to be honest apart from doing one back up using the toolkit the only other thing I did was to disable the auto scanning on start up to speed up booting the phone. A day or two after this the problems started again but this time with it no rebooting but just freezing. Eventually I took out the sd card as I remembered I had an sd card problem with my old S2 - though this is a new samsung sd card. At first I thought that was it but then a bit later it froze while i was browsing the app store and has done so periodically, though today it ran all day without freezing onvce. Then suddenly it froze again for no reason - I was just swithcing screens and it froze part way through the process
As far as I can see I have three options
1) Flash a new ROM (for the moment I am still using the stock rom having only just rooted it using Toolkit.exe from here) but not sure which one I should use so need reccommendations
2) Use the toolkit to download a stock odin flashable rom (but dont I have this already?) and then 3 reset the flash counter using triangle away (seems risky to me) install the stock rom , undo root (if necessary) and then return the phone to Samsung
3) go to Kies and install the latest update in the hope that the problem will go away - though if S User pro doesnt manage to keep root I wiill presumably have to re-root all over again.
What attracted me to S3 Toolkit was that it packaged up all sorts of options into one easy package - on the other hand this may have made me a little over confident with rooting. If I hadnt rooted it the earlier problem, though not as bad, would still have been there but I could easily have sent it back to Amazon UK or Samsung UK for repair and replacement.
My biggest worry at the moment is that whichever process I go for - or even a third option suggested here - there must be a risk that the phone might lock up during flashing or upgrade - probably not likely as it didnt when I restored the back up I had done (didnt help either) and the touch wiz ui wont be running
Anyway would really appreciate some help guys - even if it is only what you would do in the same circumstances. I guess I should have tried to have the problem fixed but earlier I put that down to maybe having too many apps and crapware and thougth rooting would help me solve it. I have unintstalled every app that I dont regularly use but it is still happening

First of all you have to be aware of the fact that rooting & flashing ROMs is always a risk, toolkit or not.
The safest way is to stay un-rooted stock if you do not know why you need root in the first place. If you know you need root, and actually also before, read the guides & information in the stickies under the General section as they explain you in detail how to root, un-root, use triangle away etc.
As for your situation, I would try to 1) flash another kernel than the stock one, if this does not work, 2) flash the most up-to-date stock ROM (you can get it here on XDA or sammobile.com) via Odin or Mobile Odin, not the toolkit (Odin is as simple as the toolkit if you follow the how-to), if this also does not work 3) try a custom rom, and if it also does not work 4) return back to stock and give it to Samsung service centre.
I wish you good luck!
Thanks for your advice

Firstly the good news is that it turned out to be a problem with the last XXELLA upgrade - I found a new one on KIES ran the update and it is fine
Of course I lost root access but expected that anyway.
I do enjoy tinkering with Systems and although I know my way around Windows I have not tried with Android until now - this is my second Galaxy so was naturally wary of bricking it if I rooted. Christmas time I bought myself a galaxy tab 2 10.1 with the express aim of rooting it and was prepared to take the risk - after a few false starts I got it rooted fine - was still wary of the phone but once the kit came out the benefit that has for me is the way you have to check things step by step systematically as you do things - my problem with doing stuff from instructions on line is that I find it is all to easy to skip a step (which I did with the tab first time around) Also with it being a system I haven't explored before I like having a step by step approach which is the same way that I learned DOS way back in time.
I do want to try some different ROMs on it to see what they offer and I would really have liked to have got some apps running from my external SD card and I also like having a complete image back up (as I have for Windows 8) so that in the event of a serious issue it is easy to wipe all and restore from new (I keep several images which I make on a weekly basis so that I don't have to re-install everything.
I confess to playing with computers and devices as a hobby - evidence of this was the 350 apps I had installed before I started purging them in case that was the cause of the problem. I pretty nearly try every new app I find just to see what it does and so there being a whole range of apps that I couldn't install without root access upset me. I am not going to rush to root again and will at least wait until the current version has been on the phone a while - just to make sure the XXEMB1 version is stable now - it has a lot of new admin features to keep me amused for a while!
Two things that disappointed me about root were that it looked as if I couldn't overclock the device to improve speed - the main CPU bar was already on max (though I didn't have time to explore more than that) and that it still seemed pretty hard , if possible at all on the hardware, to run apps from the external SD card -- as I do now with windows (using a smaller SSD ) I will have to be a bit more prudent about uninstalling the apps I find I don't really use.
I guess deep down the main reason why I want root is I don't like any manufacturer telling me what I can and cannot do with the device I paid for - one thing I did try was installing Linux but that didn't quite get finished before I lost root access.
Your advice however is very sound for people who don't like or enjoy tinkering or taking risks and I don't think I would recommend any normal phone user to root their device.
Thanks again
Just to add quickly....to overclock you need to flash a kernel that supports it.....And know what you are doing before doing it
