[Q] Hard to navigate this place... need stock firmware

Hey, so I've been bouncing around this place (as well as the google search engine) looking for a download link to a stock firmware (4.1.2) for the SGH-I317M (Bell) version.
Every link I've gotten to, thus far anyway, has been a "hotfile" link, and, as I'm sure you're aware, is no longer available.
Can somebody direct me to a download link to it? I'm looking to unroot my phone so I can update to 4.3
Many thanks in advance.

Go to www.sammobile.com/firmwares type I317M in search box... then scroll down to the Canada (Bell Mobile) firmware you want

Yeah, I tried doing that and it said the previous version was unavailable to users who aren't "members"; and when I login, it only gives me the current update (which I could easily get from Kies itself if I was going to go that route).
I've managed to find the previous version 4.1.1 via http://stockroms(dot)net/file/GalaxyNote2 - (replace the dot with a 'period' there) so I'll give that a whirl first.
Thanks for replying though!

I'm not sure what happened... but, apparently ODIN won't allow my phone to connect to the port correctly.
So, I finally got the previous website working as well; so, now I'm downloading v 4.1.2 from there.
I have the USB debugging mode on, is there something else I should be doing?

If you update to 4.3...you WILL have a locked bootloader...and currently no good way to root..
Additionally....your KNOX flag will trip and your warranty is toast...if you attempt to root...( as of today, and until the devs can fix Sammy's latest patch)...
Beyond that...you can never go back to 4.1.2 again...
Stay on a 4.1.2 bootloader without KNOX and then you can flash every rom we have along with a full return to stock if you want...
An update to 4.3 will stop any means of going back....g

I guess this is true of the official OTA update people are getting?
Man, I don't want that!

You know that Knox is a Samsung thing right? That and the Knox warranty flag that Samsung says voids their hardware warranty if triggered.

Yes, I'm completely aware... I should have said "loved", although I still love my phone and Samsung as a product; however, KNOX is really annoying at the moment.
I've been an Android lover for the past few years anyway, S2, S2 HD LTE, Sony Xperia Z, and now a Note 2. I really don't want to bash Samsung, because I think they make the best product in the market; but, yeah, this KNOX thing really needs to go.

I went from 4.3 to 4.1.1 with no issues.

My note 2 has always been stable on 4.1.1 stock and I debloated it myself. So when ever an update came out rather than risking my stable phone I would just flash the new baseband from it and keep 4.1.1, until tesh stopped updating his thread. Recently my screen cracked so I used my insurance for the first time. The new phone came with 4.3 and the knox bootloader plus the CMK7 baseband. I did a cwm backup on my cracked screen phone. Used odin to flash cwm onto the new phone, which did cause knox to show I did but who really cares since the phone is so far out of warranty anyway. Then loaded my cwm backup onto the new phone. What I ended up with is my nice stable phone with everything working plus the new baseband CMK7 stayed but the bootloader is still the new knox one. Everything is working just fine, so whats the big thing with everyone saying you cant go back from 4.3? I went from 4.3 to 4.1.1 just fine via cwm.

Cool story bro

If you use PC Odin to go backwards there are uncomfortable results.

How many of your posts are worthless? All of them? You sir are whats wrong with xda. The fact that every one thinks you cant go backwards from 4.3 just got proven wrong as long as you do it with cwm and not odin apparently.

There are multiple threads regarding your cool story.
The issue people are having is not being able to downgrade to 4.1.x OS. Its the bootloader that people were discussing and when coming from a 4.3 bootloader is impossible to downgrade to the 4.1.x bootloader/s.
Maybe doing a search in the future will get you some answers about the whole 4.3 bootloader and downgrading that you're taking about.
Good luck to you..

Ok but like I said I have the 4.3 bootloader and a 4.1 rom with no issues using cwm. So there is no issue with having a 4.1.1 rom and the 4.3 bootloader. If you have nothing constructive to add then dont post anything.

I mostly Lurk on XDA, But you sir are a different kind of stupid.
Clearly you haven't played with 4.1 long enough to see what the issues are, Its been well known that you can return to a older rom.
but knox has issues by doing so.

Lol long enough? How about since release day when I bought it? My phone is stable as can be with no force closes completely self deblaoted, working wifi tether, bunch of xposed modules and everything is pefect. For the most part the OS that a phone releases with is typically the most stable, there are obviously exceptions but I have been doing this since the G1 days and as soon as you start getting flash happy is when you have issues. Only thing I update is the baseband/modem. Also dont name call over the Internet its childish but then again most people on here are typically teenagers. Could you elaborate on the issues knox should be causing me but isn't?

This topic has been mentioned many times, there's no room for the useless bickering going on in here.

I'm not sure what you mean. To get the OTA you can't be rooted in the first place. It's only a security fix, so if you have a 100% stock phone, you can root like the last version since it doesn't change anything in regards to root.

I use Kies or Odin for updates not OTA.
My phone is rooted with Knox 0 x 0 and is working fine.
I would not touch to anything if I will have to root again after this update.
Sometimes small updates do not change the root status.
Just wanted to know if this one will take the root away.

Got you. I've never tried updating while rooted, so I don't know what will happen. Sorry.

I'm glad they threw us a bone, but it took them 5 months to fix stagefright in an update that basically only fixed that? Surely they could have done it sooner, or did a proper 5.1 update in that timeframe...

From what I read they are working on 5.1.1 for the Note 3 (I know 6.0 is out). It takes a long time (yes months) to make sure everything is compatible with TouchWiz. Personally I don't need it as 5.0 works flawlessly for me. I'm not one to need the latest OS. If my phone does what I need/want I'm happy. The only thing I worry about is security, and now that they fixed it, I'm really happy.

Where did you read that? There used to be a 5.1.1 update listed on the updates page but it was pulled months ago. T-Mobile would not even confirm whether or not anything at all is/was being worked on, or if the phone was abandoned. I highly doubt we ever get anything past 5.0 at this point.
I do agree on your other point, the Note 3 still holds up extremely well against current gen phones. I bought and returned a 6P because it just wasn't a $500 upgrade and the battery life was worse than my 2 year old N3 (original battery).

My bad. It was the Note 3 Neo, not ours. Yes I agree this phone is still awesome. I have an Anker 6400 battery, and it lasts two days easy. With all the features the Note 5 removed I'll be sticking with the Note 3 for a while, or at least until it breaks, or the next Note adds back the SD, removable battery, and IR. Those are the three things I love the most. Very power user friendly those are.

Hey, just got this phone and T-Mobile will not allow for an OTA update. When I try Kies it doesn't like the S/N (I used IMEI). Is Odin the only way? If so, is there a completely (I don't even require root) STOCK version of most recent rom or just the one prior to this? I'm currently only 4.4

Just download the current ROM (FOL1) from here http://www.sammobile.com/firmwares/database/SM-N900T/, and use ODIN to install. When you click the Kies download button you get instructions, and a link to ODIN http://dl.sammobile.com/Odin3_v3.10.7.zip. Just follow the instructions, and you'll have it updated in no time.

Unable to update S3 past 4.1.1

Hi. A few months ago I received a phone for my daughter from my mom. I reset the phone back to factory settings and it's working fine. I had to reset it back to factory again after locking myself out recently but other than that there hasn't been any issues until now. I picked up an activity tracker for my daughter recently and it wasn't connecting to the phone like it should even though it was listed as a compatible device.
Turns out the phone is at Android 4.1.1 and when I try to update it OTA it says there are no updates to download. So I tried updating through Kies and it isn't connecting the phone. At this time I started to do some more research.
The knox counter is at 2 and the device status is modified, which I have never rooted the phone and my mother can't even set up her wifi printer and most certainly can't root a phone. I installed triangle away but the phone needs to be rooted in order to do it's magic.
Do I need to root the phone in order to get the knox counter back to 0? Will this put the phone back where I can get android updates for it? I don't know where to start.

Boot into download mode. Do you see anything about warranty bit? If you do, the updates are working because it sounds like the phone has a stock 4.1.1 rom on a 4.3 or newer bootloader.

If you would to reset the knox counter to 0x0... yes, you have firstly to root your phone, then install triangle away.

Knox cannot be reset to 0x0 once it has been changed to 0x1.
Since the word "modified" appears in download mode, this leads me to conclude that the phone may be rooted and cannot receive ota updates.
It is strange that the phone is running 4.1.1 with Knox as Knox was not introduced until 4.3.
Before flashing anything, you need to confirm the phone's current bootloader and modem.

How do I confirm the bootloader and modem? I literally am learning all the language and how all of this works as I go. All I know is I have a phone that is running 4.1.1 and won't update and when I went to the download odis (I think that's what it is called) said it was tripped 2 times where I was supposed to read the knox number.
I ran to the mobile store it's connected to and they said the T Mobile Galaxy S3 phone that I-Wireless puts out was never given an update past 4.1.1 Not sure how true that is. If that's the case, I probably need to root the phone anyway to force an update (Is that what I would need to do to get it at least to 4.3?

there is an app in the playstore called samsung info. download it and it should tell you bootloader and modem.
pretty sure it is true that 4.1.1 was the last.
heres the link to the xda thread , which of course will lead you to the playstore ; but will tell more detail about the app :

I've never flashed something. Sorry if I ask a hundred questions as I go through this.
So you want me to flash the 4.1.1 that's already on the phone? Is that correct? Can I ask why? (I'm just wanting to know the meaning behind the action so understand what your thought process is so I can understand for next time.)
Just follow the directions underneath?

Is this what we're doing?

if i'm guessing right about what @audit13 & @ arthur (lol) are asking you to do is flash that firmware since the samsung info app said "firmware not found".
you might be confusing firmware version with android version. you say your on 4.1.1 which is the android version.
also if i'm not mistaken that firmware will match your bootloader which is a good thing.

frequent phone call interruptions, Samsung GT-I9192, 4.4.2 (S4 min dual sim)

Hi,
I am sadly no mobile expert and need your kind support. Since over half a year I have 2 problems
very frequent phone call interruptions
much lower battery life time
My phone/sim provider in Germany are Vodafone and Congstar. But I do not think its related to them.
All the trouble started after a certain upgrade to newer versions of Android OS, but can't remember when this exactly started. Then the battery life went down significantly and I get those annoying interruptions in phone calls up to 3-4 times in a ~15 minute call. Its so bad .. What could you recommend to me ?
Is there a better image downloadable, maybe fallback to older version ?
Or is it possible to fallback to the version in ROM ? I fear side effects and unfixed system holes by this.
Thanks for any help !
BR

Moin,
I highly recommend you to switch to CyanogenMod. I took the switch to CM right after i bought my GT-I9195 and all I can say I've never expirenced such problems either on Vodafone nor O2. ATM I'm still at CM11 as this is rock stable and battery life is quite good, ~2-3 days depending on usage
Just follow this steps and you've got nothing to worry about.
1. install custom recovery
2. take a full backup of your current system + SD Card just for the case...
3. install CM11 for your phone + pico OpenGAPPS
4. flash the latest Modem EUR region for your phone right after
5. use it for a few days without any Custom kernel and a minimum of installed apps
6. if your not satisfied restore the backup from step 2.
Sounds simple...it is indeed.
Regards / Grüße

1st of all you talk about your GT-I9195 model which is a normal S4 mini, but I have the DUAL SIM version.
Thanks but I want to stay with the normal SW train, I installed CM on a S3 1y ago and I didn't like the look and feel. So CM is not an option for me.
Besides my preferences, if I look at this article its nice to see, that there is progress for the DUAL SIM version but there are still known issues like stuttering problems and of you look down further the auther doesn't intend to create a CM official version out of it, so it looks more like a "hack" than something which is further supported by CM. Looks like an ALPHA SW and a one way road to me. http://forum.xda-developers.com/showthread.php?t=2790789
So .. other ideas ?!

Hello,
One point before flashing: your knox is 0x0 ? 1st flash result 0x1 and warranty lost.
Choice is to flash and try to solve this problem by yourself but lost the warranty or see with samsung support what they can do, but after 1st flash there is no coming back.

I have no clue about knox. I am using the smartphone with a private and a company SIM.
But there are is company deployed SW on the smartphone. Also e-mail is pure private.
I only use DUAL SIM for the purpose of being able to make company phone calls with the company SIM.
Is there no way to get rid of 4.4.2 ? I remember the phone has been sold with 4.2.x.
Is there no 4.2 stored somewhere on the phone which can be reactivated ? At least then I could check, wheter it runs more stable and whether battery life is then better. But in fact I have no Kies backup, as I hate this bloated software.

Knox information : https://en.wikipedia.org/wiki/Samsung_Knox
more important: at the end, e-fuse part: "This information may be used by Samsung to deny warranty service"

Is somebody able to explain to me in easy words, what this all now means to me ?
Does this mean, I can't do a downgrade without loosing any kind of warranty ?
Should this be the case, I assume I am stuck n the 4.4.2 path and can only hope for vendor support (Samsung).
So shall I open a case with Samsung and hope that they fix the issue should it be a SW related issue ?

In short: if you flash using odin or heimdall for the 1st time you will loose your warranty.
Samsung update is merged inside rom, it's not something you can just uninstall.
I don't know if usual samsung tool let you downgrade to a previous version
(this time without knox issue since it's pure samsung way to update)
