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

ok ill explain the best i can for you.
Lets say for example that the bootloader was unlocked for the flex 2, if we downgraded with the current method that I did, then youll end up with a brick BECAUSE...after the 5.1.1 update, the bootloader was also updated, but if we had an unlocked bootloader, it would be no problem because then you can get right into fastboot since the bootloader is unlocked. however the reason my flex 2 bricked was because you cant downgrade bootloaders unless there is a specific way to do so, and if its unlocked...well since mine wasnt on the flex 2, when i flashed the TOT from ZV5 OVER a ZV6 bootloader, the rest of the partitions flashed, except for the bootloader end of it because it returned a "Version on phone is currently newer than the one being flashed" and declined the flash, since ZV5 wasnt build around the ZV6 bootloader, it doesnt know how or what to boot..
thats just a simple version, going into specifics is the Devs department, but in lamen terms, thats whats going on..if we had an unlocked bootloader it wouldnt be an issue because we could flash an older bootloader without the phone rejecting it. but once root is achieved on 5.1.1 then there will be a way to restore the FLex 2, the G3 you have although it may not have an unlocked bootloader, its been out for long enough to where exploits have been discovered, but if youre referring to upgrading and downgrading on Custom Roms, thats not the same thing, its only for official TOT's and KDZs or Official LG Firmware.
it would be like trying to flash a sprint variant with a tmobile rom....its just not built for it, its like having a Ford mustang with a V6 and trying to put a V8 motor in it without changing the computer/wire harness etc. it will fit...but it just wont work.
did that help for you to understand?

Ya i understand that part... Ive dealt with bricked phones... Ive recovered all but one.... Why are some able to downgrade though... In another thread soomeones says hes gone back aand forth a couplw times... Thats why i was confused..
So there's no way to root the Sprint lg g flex 2 (ls996) once it's on 5.1.1? Because we can't downgrade right? Wish I knew this before I bought one off Swappa.

Yeah I don't regret buying the g flex 2 considering I got it for $260 on Swappa. Really happy I got top of the line hardware for this price. I'm sure root will come or maybe a way to unlock bootloader so we can downgrade.

Ok so I purchased a brand new Sprint G Flex 2 on ebay http://www.ebay.com/itm/221950977883 and to my surprise it was already rooted with firmware ZV6 so now I can't take OTA updates since it stops updating halfway through the update and the green Android guy lies on his back with the "error" message. I already did the full unroot method using SuperSU but still a no go. Before I send this phone back to the seller I want to make sure if there is any hope in fixing this issue and allowing the updates. I also downloaded the root checker app to see if root was gone and it states root is not configured correctly. Not sure what that means as I used SuperSu to fully unroot. Any help would be appreciated as I only have 14 days to return this device to seller but I do not want it rooted as it prevents updates through Sprint. Thanks.

Download the version you have, DO NOT I REPEAT DO NOT DOWNLOAD ANY VERSION THAT ISNT THE ONE YOU ARE USING YOU WILL BRICK. ZV6 for ZV6.
Here are the stock image files uploaded by me.
Follow this guide its the root guide but its the fastest method to unroot using stock images (same procedure). Good luck! :good:

Those who want to unroot and go back to stock ZV6 (so they can get the OTA ZV9 update) should be able to use these "dd" flashing instructions:
http://forum.xda-developers.com/g-fl...5-1-1-t3169212
along with the stock ZV6 firmware image from here:
http://forum.xda-developers.com/g-fl...k-img-t3217089
However, you will not only lose root. You will also lose the SIM carrier unlock. After reverting your phone to stock, your phone will be carrier locked to Sprint. That's because carrier unlocking is done by altering some "node db" system files.
After applying the OTA update to ZV9, you will have to redo both the carrier unlocking and the rooting of your phone. It's doable, but it's just something to keep in mind.

Thanks for the info. I have one question though. I did the unroot method using SuperSU and was wondering if that will not be enough to get OTA updates once I get my Sprint SIM card installed. From my knowledge if the system files were messed with OTA updates won't work correct and in this case you stated that carrier unlocking involves altering node db system files. So even if I did the full unroot method using SuperSU the altered files would remain correct?

I believe you are correct. Since the eBay seller altered some system files (that's probably why he rooted all these phones and installed SuperSU) to achieve the carrier unlocking, the OTA update for ZV9 is failing. Even if you unroot and delete all traces of SuperSU, I think the OTA will still fail. The update script probably does some sort of checksum verification of all the Android OS files before proceeding.
Also, I don't think you need a Sprint SIM in order to do the OTA update. I believe the OTA comes from LG's servers, not from Sprint. I've heard of people getting the OTA update even if they are using an AT&T or T-Mobile SIM. As long as your phone has data (cellular or Wifi) I think the OTA will download. But as you've found out, it won't install unless you go back to stock.

From the guide you just have to follow
1. Download and extract the stock img.
2. Transfer it to the root of your internal sdcard (images are usually named ZV6system.img) avoid moving the complete zip.
3. Put your phone in download mode (you can figure this out)
4. Use the dd command for your variant in your case LS996, just change the name of the ¨rootedsystem.img¨ to the one you downloaded.
Aaaaaaaaaaaand you´re done :good:

I did everything in the guide and phone even rebooted when I typed LEAVE after the "#" prompt but I still can't take OTA and Android guy falls on back with "error" message. I have another question when I click in the status section in the About phone settings and I scroll down to Brand it lists Chameleon. Is this normal?
Did you download the stock image from the forum I made?
Cause if you flashed your current system.img then you flashed the rooted one.
Make sure you are using the Send_command on the diag port of your phone if you arent doing this then you wont flash correctly and phone will stay rooted.
And yes, when the phone hasnt been unlocked internationally Chameleon is the ¨Sprint stock way¨

I did flash the ZV6 stock image from your forum http://forum.xda-developers.com/g-flex2/general/return-to-stock-ls996-stock-img-t3217089 and I used the send command to port 5 because that is where the Diag port is when I double click the ports.bat file. I actually tried this method twice and I still am not able to update without error. Maybe I do need a SIM card installed and will try it tomorrow when I get my SIM delivered from Sprint. Thanks a lot for the tips though.

Thats kind of weird you know, I OTA updated my phone even after international SIM unlocked.
How long does the flash process take? If it takes less than a minute then its not doing things as it should.
Did you enable USB Debugging before flashing?
Have you tried to Factory Reset after flashing the stock ZV6 system.img?

I do have USB Debugging enabled. The flash process takes around 1 minute and then the # shows up indicating it finished and then I type LEAVE and phone reboots. I even tried the factory reset after flashing it with the stock ZV6 image. This is very interesting but I will wait until tomorrow to make a decision on whether to keep the phone when I insert the SIM and see if that helps any. Thanks Alex for all your help.
I forgot to ask this but do I have to type the commands or is copying and pasting ok.

Well it depends on how did you copy/paste the command.
To flash the ZV6system.img it should be like this:
dd if=/data/media/0/ZV6system.img bs=8192 seek=58368 count=522240 of=/dev/block/mmcblk0

Thanks for your patience with me. Do I have to run both the dump and flash commands as I have only been doing the flash command and maybe that is the problem?
is this how the commands should be typed?

I'm in a similar boat w/ a slightly different issue. I bought the same phone from the same guy and have not been able to get it to activate on Sprint at all. Well, it "activates" but then it errors on updating the PRL. I have LTE data, but no call ability. It is very strange.
So far I have:
Unrooted via SuperuserSU app that was installed
Taken it to Sprint store and had them do everything they could (while being condescending about buying a phone not from them)
Played with every setting I can find
Factory reset many times at many stages
Flashed to the stock ZV6
Installed 2 OTA updates (now a third is coming through)
And every time, I get a your phone has been activated message, followed by trying to update the PRL and failing, leaving me in the same place I was to begin with. I'll try it again after this latest OTA update I'm getting, but I'm running out of things to try and I'm extremely frustrated lol. Anybody had the same problem? Any ideas? Anything? I don't know if maybe it's just a defective phone... sigh. Thanks in advance for any help!

Did you get a new SIM card from Sprint or did you use an old one because Sprint told me they need to send us one that has been programmed for the LG G Flex 2. On another note when flashed the stock ZV6 image did you send both the dump and flash commands and did you have problems getting the updates before you flashed to stock. Thanks.

On another note when flashed the stock ZV6 image did you send both the dump and flash commands and did you have problems getting the updates before you flashed to stock. Thanks.

I picked up a new one at the Sprint store. I would hope they knew which one to give me haha. I only used the flash command. And yes, I had the same issue as you did with getting the updates before I flashed. No problem with that now, 3 updates later I'm on ZV9. Now if I could just get the phone activated...
My LG G Flex 2 keeps downloading an OTA update. When I opt for installing it, the phone reboots, but I get an error with fallen robot on the screen. Then the phone boots normally.
But then downloads LS996ZV9 (?) via cellular network eating my traffic and I get the same problem.
Is there any way to switch to downloading OTA updates via Wi-Fi only? And how can I install the downloaded update? Is there any way to avoid downloading updates from unknown sources?
Are you rooted? Have you altered/frozen/deleted any system apps? If so, the OTA update will fail.

What version do you currently have? ZV8=?
Maybe your phone has some altered system files and thats why you cant update.
You should download the correspondant STOCK system image and flash it.
That way you can OTA update to ZV9 and that will make your problem stop.

I have ZV6. May be some files are altered indeed. Will try to factory reset the phone first.
Is the stock ROM available on lg or sprint websites?

No. Theres no rom anywhere. Do not factory reset first... If you do that you'll have to send it back to LG if the phone stays in bootloop or security boot error...
Anyones has figured this out, I'm on the same boat. Everytime I tried to update, an error occurs.
Yours probably came rooted from the seller. LS996 is Sprint variant. If you are not on Sprint network and your LS996 works with your network, that means your system files were already modified when you purchased the device. OTA updates wont work on rooted devices. If you really want to take the OTA updates, you will have to unroot first, by flashing stock system.img. You can download the ZV6 stock system.img here. You can flash it using this guide.
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
