[Q] Plz Help 4.3 down to 4.1.2. rooted tried a few

So I'm by no means super knowledgable with this stuff but I've rooted a few phones, played around with CM on my old evo but for the most part I enjoy rooted stock.
I have Galaxy S3 Sprint 4.3 updated OTA from a rooted (4.1.2). When I took the OTA I lost root, no big deal I used Odin and flashed the CF auto root, it said it removed knox and I had root back. Cool!
In short 4.3 sucked, wanted to downgrade back so things like TrevE mod would work again and it wouldn't be so buggy. I tried to use odin to flash "KIES_HOME_L710VPBMD4_L710SPRBMD4_1130792_REV03_user_low_ship.tar.md5" but it gave me the "Use Kies Recovery and error occured" message.
So I then used odin and flashed TWRP and my phone booted.
I'm back on 4.3 rooted.
I've tried picking through the forums and interwebz for answers but I get mixed messages and info on international versions and what not.
I'm tired of trying to figure it out and really could use some help downgrading back to 4.1.2
Thanks,
Brandon

The 4.3 OTA installed a locked bootloader, which will prevent you from ODIN'ing back to a previous version. you can flash any ROM you would like from recovery, you CANNOT downgrade the bootloader. As of right now, if you have knox, you are stuck with it.
You are extremely lucky that you didn't brick your phone by using odin to flash a non-4.3 tar. I wouldnt try again.
My advice is, remain rooted with a custom recovery, and find a ROM to your liking, and flash that.
I have also heard that we cannot flash custom kernels on the knox (MK3) bootloader as well, but I havent verified that.

Thank you for the response. Is CyanogenMod an option then? If I go to CM could I flash back a stock 4.3 rom in the future?
As an added bonus question does CM allow wifi tethering?
Again thank you for the response.

CM is certainly an option. In fact, its what i am running now. CM11 12-24. Runs great. You can always odin the stock mk3 tar and go back to stock unrooted, at any time.
in order to flash cm11 you MUST be on TWRP 2.6.3.1 or CWM 6.0.4.5 or newer or the assert check will fail.
not sure on the tethering, but im pretty sure it definitely works on cm10.2 and i think it does on 11 as well, but dont quote me on that.

Tethering is available on CM11 just like it was on 10.2; would strongly recommend latest Philz Touch Recovery over either TWRP or CWM though. Although it is based on CWM, it has proven to be pretty much the superior recovery option for flashing any Android build number, plus it is highly customizable.
Philz Touch Recovery

this is how to downgrade

do a factory data reset then use odin auto root from computer ok...... after boot u will get a security message supersu will be unfortunately stopping this is ok..... then u will need to download the supersu.app to root of sd then manually install this will update it and now u can turn off knox and have root... then go to market and download odin mobile then flash your .tar file u want and you will be good to go 4.1.2 doesn't have knox and has a unlocked bootloader so have fun bro this method may work for other phones

Do you realize that this thread hasn't been used in a couple of months? I would assume the author has no more need of advice based on the inactivity. Also, once Knox is installed, it is on the phone to stay. PERIOD. NO DOWNGRADING POSSIBLE VIA ODIN. Custom ROMs of any build are fine via custom recovery, but any attempt to change the bootloader will trigger Knox and brick the phone. Dangerous info to be posting here, especially since someone else who doesn't know better might try this.

Looks like your having the same issue I was having. Check the 4.4 update thread about rwilco's modified restore. The one with the sboot or boot.ini in it works. Trust me It works I just got my phone back to 4.3 then back up to 4.4. If u have any questions pm me.

If it's the Samsung screen u need to go into factory recovery and do a factory reset. If u stuck at the note 2 screen u need to use odin and use the modified restore that was posted on the 4.4 update discussion thread. i think i used odin 3.4 or something. Ill turn my computer on to see.

ok to make things short as possible. i dont want this discussion to get out of hand and i will be as helpful as possible. I was stuck on the samsung note 2 screen. i couldnt get past it. tried everything for like 2 days and then rwilco12 posted his modified 4.3 restore on page 50 of the Note II - the 4.4.2 update - discussion thread. all i did was flash that through Odin3 v3.04. just reboot checked on PDA. nothing else. when it rebooted it took a while but it booted to the samsung screen that changes colors. it stuck there so what i did was reboot into recovery mode and did a factory reset. after that it booted into 4.3 no problems.

Honestly I'm not quite sure. What u could do is use billards mc2 then ota to 4.3 and when u reboot if u soft brick again just use the modified restore again. If u want to try it go ahead no harm in trying. i might try it later but chances are its going to fail anyways. Since downgrading from 4.4 is what caused the problem in the first place.

Puffyjello,
I simply flashed the OTA 4.4.2 in stock recovery and rebooted to the update no problem. No new Odin's of MK4 or anything, just flashed the OTA after i used your method to unbrick.
I then Odin'd Philz, flashed SuperSu and now im rooted and on 4.4.2, no problems.
Again, thanks for the help with the 'unbricking'!

Np. And what I thought u meant was going back to mc2 from 4.4 then ota to 4.3 and see if it bricks again. I wasnt sure if it would. Ne ways I'm glad everything's fixed. And I hope anybody that has this problem follows what fixed our phones. you guys take care. Running stock deodexed ne2 and loving it. Can't wait to try out their s5feat rom when they release it.

Does the LJC_Stock_With_Count_Reset[FINAL].zip still work after ota 4.4.2 ?
This to me is the best back to unrooted stock. It resores the LJC PIT, kernel, and modem. Compared to all the other stock roms; I find this one read and writes easier with QPST & CDMA-ws.
Im currently running stock rooted MC2 with stock LJ1 baseband.
In my opinion so far this is the recipe for this phone. Oldest basebands seem to have better battery life. I'm not really sure if the newer modems are actually faster causing the battery to drain faster, or generate more compression and share more detailed information with big brother which would also cause it to slow down.
I have this theory the manufacturers purposely slow peoples equipment down with the OTA after the first couple years to motivate them to buy the newer model flagships that supports the same software more efficiently. maybe I'm just crazy but can someone please try the back to LJC stock unrooted. and let me know if it works better than the back to stock MC2.
plus it could possibly be better doing all the OTA to 4.4.2 from an older stock rom.

[Q] T889 Bricked, TWRP works, Wiped Everything, Have Android Toolkit, Now What?

Made big mistake. Downloaded Android Toolbox (PRO). Rooted 4.3 successfully. Trying to go to 4.1.2 from 4.3. Did Titanium backup. Downloaded Mr Robinson root66 ROM. Using TWRP (latest), made mistake of wiring everything (not extsdcard). Now stuck at the first Galaxy Note screen when the phone is turned on or I can get to TWRP. Feel dumb as a stump, but can't seem to move from here. Help!
All I really want to do is get back to an operating phone, be it with 4.3 or 4.1.2.

Sorry for the long-winded whiny first post. I'm just stumped how to flash a ROM back on the phone. Can I use TWRP to flash a new ROM? I usually have been able to muddle through but I'm really confused at this point. Anyone have an idea?
Thanks

If you can get into recovery you should be able to flash a custom rom, If not you will have to use Odin and flash a t889 rom to your phone preferably mk7.

Does your phone go in to download mode ? If yes, does it recognized by ODIN ?
If TWRP is working then you should not have any problems flashing any 4.3 rom via TWRP.

Thank you for the hint. I finally woke up after these replies and made the phone into a non-brick again. XDA continues to be my source for all things related to my toys.

New to rooted LG GPad-have questions

Hi folks. Long time rooter/rom user of phones and tablets. I have some questions for my V500
Since it is rooted, would this be the next step - http://forum.xda-developers.com/showthread.php?t=2641409
(Installing TWRP for a custom recovery)
Since I'm on 4.4.2 with a V50020d base, would I then focus on getting 4.4.2 base roms and flash them via that TWRP I installed?
This does seem like a really fun and snappy device. From what I can tell, it has an IR Blaster right? Are there any roms that don't work with the blaster (I see this sometimes in the Galaxy Tab roms for devices that have the IR blaster)

Once you root, the next step is installing TWRP so you can install roms.

I also have the V50020d UK version.
Stumproot which is available here worked fine for me, easiest root i have ever done. Just install apk and your done.
Installing and getting custom recovery to successfully flash a ROM is another story. I have managed to get TWRP flashed to the device and boots correctly. However it fails when i try to flash CM11 or any other ROM. After reading around I think I may have to downgrade the stock 4.4.2 to 4.2.2 in order to get TWRP to flash. I am not struggling to find the correct stock 4.2.2 kdz firmware for the v50020d device.
It's been a bit of a head scratcher! Let me know how you get on with yours.

Cracked it today. I've written a guide for all UK users who are stuck with V50020d, compiling all the info. http://forum.xda-developers.com/lg-g-pad-83/help/v50020d-uk-root-twrp-flash-stock-4-4-2-t2938914
Hope it helps

I did mine with towelroot. I'll be looking to flash a custom recovery soon. I wanted to pop in here first to double check before going ahead with a recovery and a rom.

I new to LG and have 2 of these for my boys.
I have a us and uk one, i assume these will need different ways of rooting and flashing twrp etc?
I rooted one with Kingoroot no issues, but damn, getting cwm to install is a mare.
Both mine are on 4.4.2.
Looked at so many tuts, they all change due to time and i had to give up as was draining me.
Any tips on how to get cwm installed fella.
Best wishes

[Q] Downgrade from Custom 4.4.2 to stock 4.3 possible?

Hi everyone I hope this is not a repetition of some old thread (I tried but couldn't find though).
I was using my note 2 (T889) on stock 4.3 which i previously flashed via odine. A couple of days ago i came by this good looking kitkat based rom ( eZKAT v2.0 ) and went on to try it. the rom flashed flawlessly and after flashing my modem i got the signals as well but the wifi was not working. tried using dr. ketans wifi patch but didnt get the wifi to working. Anyhow, I decided to go back to 4.3 via odine. The odine flashing completed successfully but i got stuck on T-mobiles boot screen for hours.
Is there anything called "you cant go back to 4.3 from 4.4.2"? If yes, then whats the way around? I really need to go back to the stock.
Thanks.

I had this problem on my Note also. Downgrading versions of Android requires a data wipe. You will need to reflash your 4.4 ROM then backup your data if you want. Save your backup to your computer then install the 4.3 image.

I already tried that but still the booting stuck on the t-mobile logo. I read somewhere that locked bootloader don't let you downgrade to previous version. Is this true?

In that case. Try finding a 4.3 rom that's close to stock.
Sent from my Nexus 7

The locked bootloader is always in stock firmwares i.e 4.3 for the Note 2 but not in custom roms meaning u can even install Lollipop custom on it & downgrade smoothly, i have done that many times. The problem is 4.3 stock firmware has locked bootloader hence downgrading still keeps u in 4.3 bootloader even if u remove all the KNOX files.

Stuck trying to downgrade from custom 5.1.1 to stock 4.3
Hi, i have a problem like this, upgrade to a custom 5.1.1 and then sell the phone, the new owner wants to have it stock, i try to downgrade to 4.3 but i cant, in odin i set the phone to flash it but seems like it doesn`t recognize the phone and i dont know why, so, i decided to try in recovery mode installing from the sd card but the sistem abort, so, i don`t know what to do, i`ll appreciates any help, sorry for my english, i do my best. (i have root access before upgrated to 5.1.1).
