I have done flashing and rooting in the past on both a Samsung Charge, Nexus and S3, but it's been a while. Ive used Odin, and the TOOLKIT, and am somewhat familiar with both.
I have had my S3 for several years, STOCK, STOCK, STOCK, and liked it just the way it was. I had a WIFI tethering app, SVTP that worked, and didnt take updates for fear it would quit working, well I accidentally took an update, and now it doesnt work.
Id like to reflash the phone back to a previous stock software, I forget which one I had, but currently here is my phone info
SCH-I535
4.3
I535VRUCML1
KERNEL 3.0.31
build JSS15J.I535VRUCML1
hardware I535.10
I believe I had Jellybean, or a 4.0 firmware.
How should I flash this back, and where can I download the files and the correct version of ODIN?
So i attempted to flash an older OS 4.0 i think, with odin, and It said ABOOT FAIL! and I kind of bricked it. Was I supposed to unlock the boot loader or wipe the device before doing this?
Now I got it connected to kies and am in the process of downloading latest Samsung OS to phone, so i can try again.
What did I do wrong?

As long as your not on the NC1 or NE1 baseband/firmware you can indeed revert back to an older version. And you do indeed have to unlock the bootloader to revert to a previous version of Android
In my personal opinion your best bet is the casual root/unlock method which will do both for you

so i have NE1 now. Why cant i downgrade anymore?
Tonight im going to reattempt to flash 4.1 with odin, unlocking bootloader first.
my only othed issue is i can find very few versions of Stock OS on web. There should be like 5 or 6 for this phone, ive only found 2 or 3. Please point me in direction of any stock OS files.

Because your on a locked bootloader and downgrading now would brick your device

Is there no method to unlock these firmwares currently?
if so does anyone have an S3 for sale that has older firmware?

Check swappa for that. I know brand new ones have the newest firmware, your better bet is swappa
And no they are locked down tightly, unlocking is nearly impossible

what if i soft brick it on purpose, can i somehow download an older version via kies once soft bricked?

No, you can't get around the locked bootloader. Your stuck on it

I believe even the 4.3 ML1 update will lock your bootloader. The 4.4.2 NE1 definitely will. There's no known way to revert back to an unlocked bootloader.

You are correct. I did a quick search and those who took the 4.3 ML1 OTA are indeed on a locked bootloader

Hi guys a bit of help please. I'm about to fully flash my device back to stock.
I have a o2 UK variant s6. I have downloaded the correct 5.1.1 rom via sammobile. However the worry I have is about the bootloader, do I have to do anything with it.
Thanks in advance.

You shouldnt have to if you have any concerns just do it though smart switch on your pc once the program opens up click over to emergencey recovery and punch in your device name eg. SM-G92xx and your serial number make sure its all capitals it will download the correct software for your device and flash it for you. If this dosent work then you shouldn't have problems with odin as long as your not downgrading from 6.0.1 to 5.1.1
That's the wierd thing. Smart switch will not recognise my phone. Windows dose and Odin just not smart switch. Is it because I'm rooted running a custom rom.
I was on 6.0.1 but reverted back to a 5.1.1 custom rom. Dose that make a difference.
Thanks

Im rooted on custom rom and it sees my phone hmmm well aslong as u flash a 5.1.1 bootloader when u came back you should be fine
EDIT:
What files do I need from storagecow link in the OP to do a 100% proper flash? The .zip only contains boot.img and system.img but I've heard you need the modem file as well?
There's others on storagecow like patched20fboot.img? rpm.img? tz.img? Should I grab all the files and put them in a zip and then flash? Or should I flash them one by one in a certain order?
I GREATLY appreciate any help. Please note I'm only after official LG firmware, no cyanogenmod or anything.

Hiya. Brand new to XDA forums so I apologize if this has been mentioned before.
I'm gonna make this as quick as I can. I bought an unlocked LG G3 from ebay
Opened it up and turned it on, first thing I did was check for firmware updates because it was still on KitKat. Nothing for some reason. (if you know why please answer in your response)
I'm new to rooting/flashing firmware but I did my best at researching on how to flash it to Lollipop which I successfully did but I had a few small problems afterwards.
Google Chrome refused to update no matter what I tried, taking screenshots wouldn't work and I couldn't delete the firmware files on the internal storage. So I ended up reverting back to the stock KitKat room, unrooted with no TWRP.
This phone is gift to someone so I'd like it to be in perfect working order, but I would like it to run stock LG Lollipop as well as Marshmallow when it comes out soon.
First question is, is there a way to update the firmware with an official LG software or do I have to flash it? I've heard when you're 2 firmwares behind OTA no longer works.
If not, what files do I need from storagecow (I can't post the link cus I'm new) to do a proper flash? The .zip only contains boot.img and system.img but I've heard you need the modem file as well?

You'll have to root, and use a custom stock rom. It'll only OTA update if you insert an active AT&T sim.
Hello folks! Today I got successful in downgrading my Verizon s6 from android marshmallow to android Lollipop 5.1.1 but still there is no root for 5.1.1 too! . Many people need it, MM is a bit buggy lollipop is much more faster and battery life is good too for me at least. So your data is going to wipe and be careful about flashing with odin. I hope you are familiar with it if not google it. Many good guides are available. Don't forget to turn off reactivation lock if enabled.
1- flash OK7 firmware which is 5.1.1 https://drive.google.com/file/d/0B9jRsxJwh4klTEpMWFF4UkNSdXM/view
2- after flashing OK7 your phone will boot up but it will stuck at red verizon logo (Bootloop). now press and hold volume up & volume down + power button until a black screen appears with 5 options press vol down and highlight 2 option factory data and reset press home button.
Voila your are now downgraded at 5.1.1.!!
Everyone know it
This guide is for noobies.
So 5.1 don't have root either? What's the reason to downgrade then?

Anyone in this thread know how to back up my apps and data before I downgrade without root?

This will not trip Knox, but may I understand the logic of wanting to downgrade, but wanting to get OTA updates? Then why are you downgrading? Root isn't permanent.
Ota updates simply for the reason in case I ever do decide that I want to upgrade to marshmallow again, I'm not downgrading for root, but to test if it'll improve my phones battery life as I've seen many threads state
Ok so I went ahead and did it but now my phone wants to update to MM again :/
Any way to disable the update?

Hey guys,
My dad has a SM-G930A 6.0.1 unlocked running on T-Mobile. It is starting to show it's age (battery drain, apps not running like they should, etc.) and is still stuck on 6.0.1.. From my understanding, it should be possible to flash to SM-G930T, however I am a bit lost as to where to begin the process to do so. I tired going straight to 8.0 by flashing the SM-G930T 8.0 firmware files but this didn't work (I didn't think it would work, but it was worth a try). With that said, would it be better for me to just stick to updating to SM-G930A 7.0 via the guides posted, or is there a way for me to Flash the SM-930T 8.0 firmware? Thanks in advance.

Wow you guys really get screwed over there in the US with cell phones. It's a pain in the a** to do anything with your phones.
Anyway I'm guessing the phone was originally AT&T right? And now it's unlocked to any carrier.
If you just want to update the phone to the latest firmware then just flash AT&T Oreo. It won't affect the SIM it will still work as before.
If you want to flash any other firmware including T Mobile then you'll need to unlock the bootloader on the device and that's a whole different ball game. With plenty of guides on how to online.
Make sure you back up all the things you want to keep before flashing

Thanks for the reply! I appreciate the direction. You are right, US phones are a pain. And yes, the phone was originally an AT&T phone, but was unlocked.
As for unlocking the bootloader, I've found different sources that say that unlocking the bootloader on this particular phone is not possible with this particular phone. I did read something about an engineering bootloader being used to get around a locked bootloader for rooting. Could this be used for flashing as well?

That's not entirely true. Using Odin you can flash any USA firmware onto any other USA device, no bootloader unlocking required.
It's very common for people to flash G930U over their G930V/T/A/P devices to remove bloatware

It's unstable and only lets the device charge up to 80%, your best bet woulld just be a full flash with Odin
This guide is a bit dated but it's the best one out there. Just make sure you google the latest Odin and use all 4 firmware files when flashing https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin

Thanks for the reply! I had tried flashing the 8.0 G930T variant last night with the latest version of Odin and the PrinceComsy version and got a Model Mismatch error. I read that the modified Odin3 v3.13.1_3B_PatcheD would let me flash the firmware and ignore the Model Mismatch error. However, I didn't go through with it because I was not sure if I would brick my phone and instead erred on the side of caution and made my post here. Would I be safe to flash the files from SM-G930T_1_20180625111401_xf3965l42p_fac onto my current device?
If your firmware files are from a trusted source like sammobile, updato or samfirmtool then it should be fine
Odin3 v3.13.1_3B_PatcheD seems to have positive feedback here on XDA so should be fine too https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

Greetings-
I apologize for jumping in an already created thread, but I think I am in the same situation, and like to verify with you both before I use the advice please. I have a SM-G930T that I just purchased, and really like to run a custom rom. But I understand I can not because I have Android 8 on it. I know how to use Odin, and have the latest version plus you guys talked about it here. I have also already downloaded the stock rom from sammobile site. What are my options? Is there a rom I can flash the phone with using Odin that would provide better performance, less G..bage, and more battery life? Is there a way for me to root the phone? I really need an app that requires the phone to be rooted.
Thanks

Ok, so flash any unbranded Stock Rom for your device using this version of Odin which has been specifically modified to flash US devices. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 PatcheD.zip is the file you want to download.
Then when you have checked the phone is working ok on undrnaded firmware you can go ahead and root the device using this method which is again for US Qualcomm devices. https://www.****************/2018/0...on-galaxy-s7-and-s7-edge-on-android-8-0-oreo/
Take you time and read instructions.

If I understand it correctly there is no unbranded firmware for the US, its all network specific but you can flash unbranded UK firmware and it will work fine, UK BTU is the one you want from sammobile.
Load into the modified version of Odin and flash.

Yes that's the right one but like the beanvee and i have said there is a specific way to flash this stock then root the device.
You also need Samsung USB drivers installed so your pc can talk to your device, there's plenty of guides around how to flash with Odin and what you need to do beforehand, the only difference with you is the version of Odin your using and then the method of rooting afterwards.

Thanks. I have used Odin before, and I already downloaded the patchD version of Odin from the link. Thank you so much. I'll keep you posted on how it turns out. I still do not have a verified version of a custom recovery for this. Do you guys know of any? I found this link but the link to the suggested twrp does not work. I think it is this one. But I can not be sure. The original link points to a slightly different url.

Nope do not use that TWRP, it will flash TWRP but not boot it and you'll be stuck on Samsung logo forever.
There is still no way to unlock a Qualcomm snapdragon bootloader and i'm not sure anyone is working on it anymore.
All it means is you need to flash custom Roms via Odin or possibly the inbuilt S7 recovery, you just need to check the ROM is in a format which can be flashed that way.
With regards to finding a TWRP solution you'll have to do some serious searching on google and read everything.
There are already several de-bloated stock Roms on the forum if thats what you want to do. Root and custom recovery TWRP are two different things though, you get rooted so your good to go?

Yes root is my main goal, and you are right the debloated roms will work just fine. I can do w/o twrp. Just double checking here; since I am flashing the UK rom, and I believe one of the comments on this thread was how US images are locked tighter, would not I be able to find a UK version of TWRP for my phone? Just checking.

Now pull up a chair and listen closely.....99% of the American devices (including yours) have an extremely uncooperative Qualcommm Snapdragon cpu at it's heart and thus refuses point blank to play ball. The online community have done a fantastic job creating the modifications you are now using. The rest of the world (i'm happy to say) enjoy the S7 with an extreamly cooperative Exynos cpu at it's heart. It just loves to be fiddled with, it's a whore of a chip, constantly on the go with all kinds of neat tricks.
Anyhoo... my point is, the software has to be compatible with the hardware you catch my drift? All the cool little programs are written with a specific piece of hardware in mind, unfortunately for you guys Qualcomm is the ice queen.

Thank you so much. You guys are amazingly patient, and informative. Thank you for educating me, and helping me achieve my goal.
I have tried a few times but can not flash the files. I have attached screenshots, and followed the instructions here. Do you see anything I should be doing differently?
I initially thought the code came as one tar file, which I could flash, but it was a zip file, which I had to unpack.
