Procedure for downgrading android 4.3

Hi, I am sure there are countless threads out there already talking about the inconveniences that 4.3 bring and the problem you get for trying to downgrade. I have read through many of them and I think I have the general idea of how to downgrade relatively safely without running into the problems I am currently aware of. I want to confirm what I know. I would like to be informed before I do anything, especially something as dangerous as a downgrade attempt.
So all that I am aware of right now is that 4.3 brings in a new bootloader, attempts on trying to change the bootloader will result in hard brick, so does that mean any previous firmware that does not flash a bootloader will be fine? will stock firmware from sammobile work? I am looking at this one right now,
http://www.sammobile.com/firmwares/3/?download=16006
Second problem is 4.3 also changes the efs format, any modem before I think MG4 won't be able to read it, and you won't get network, this should be easily fixed by flashing the latest modem here
http://forum.xda-developers.com/showthread.php?t=1831898
...right? also the modems are made custom recovery flashable, if I want to use odin instead, do I just unzip and put the modem.bin into odin?
Also plans to root first and backup efs, I hear you have to go through hell to get it back if you lose it...
Doing any of those should trigger the knox counter...so basically anyone that still have warranty left and plan to use it cannot do anything...even rooting...right?
But that should be the least of your worries if you are determined to downgrade...
I am not sure if that is all the trouble I will run into, I don't know what made samsung so confident that they can even say it is impossible to downgrade, they meant to say difficult but you can do it, right?
also I am on SGH i747m bell.

Roms

Hello there. Just wanted a question answered. I just bought a note 2 (coming from the HTC One) to try the note line without breaking the bank. What I wanted to know is if I could flash international note 2 ROMS on the tmobile version of the note 2. I'm loking for a ROM that basically mimicks a lot of the note 3's functions and also has unique looks and customization with exposed and wannam. I think I came across one on the At&t forums so I also wanted to know if we could openly flash At&t roms on this variant of the phone as well without issues. Also, ive read a little and have seen many posts about issues with wifi and fixing it with some kernels. Can someone elaborate on that please? Thank you for your time.

If your T-889 is still on a 4.1.2 software version and hasn't been updated to 4.3 you may experience wifi initiation problems on 4.3 touchwiz based roms.
You can remedy this by either updating to the new official 4.3 version which installs the knox enabled bootloader, or use PC odin to flash Dr Ketan's bootloader to enable the rom and device to work out wifi start up. A third option is flashing a custom kernel specially the devil kernel by derteufal1980. I have had mixed experience with devil kernel but overall it is good. I personally stock with the stock kernels as they do everything pretty well.
Personally I would go with the Dr Ketan bootloader patch option as it doesn't "burn any bridges" or limit future use like the official bootloader can (causing version regression hassles, allowing knox to pop e-fuses etc). Using the bootloader patch will allow things such as triangle away to work so that you can get back to official stock status for whatever reason you have (selling the device, return for factory service etc).
Others will tell you differently for a variety of reasons that are, at least partially IMHO, valid in a practical sense. Their opinion is valid for their circumstance, I have different needs than they do. YMMV.
If you flash the Dr Ketan bootloader patch you will also want to flash the current modem. There's are odinable versions and some for installation with a custom recovery. They are all the same except for the installation method. If you choose the official upgrade methods you will automatically get the new modem during the process.
There is no downside to installing the current modem, it makes signal acquisition for LTE quicker and I haven't seen it do anything worse than the previous versions.
Before installing anything read all the applicable thread info and check your md5 data.

Got cha. Thank you! I was checking out that rom too. Looks clean and nice. so im assuming being t-mobile phones, if we want to flash international version rom, the section that must be used is the 7105 correct?

Before you flash anything, boot into stock recovery mode and check if the screen has a line saying knox warranty void or something similar. If I only has device counter you can go ahead and do what you need to do. Once the knox bootloader is installed, there is no going back (a big reason why I prefer the patch option).
If it has one that mentions knox counter don't bother with flashing any bootloader stuff as it is already been taken down the 4.3 update path.

Wow, Seems like knox is a giant headache from what you;re telling me. But even if it has the knox bootloader, will i be able to root, flash a custom recovery and custom rom or knox totally just kills that?

Knox is an obstacle to be dealt with. You can do all those things with it. Doing things like reverting to previous versions of Android are more frustrating (and less obvious) than with the old bootloader.
Also, once the knox bit is tripped there is no known revert method. If you ever need knox functionality you are out of luck. Most people will never need it at this point. Samsung may or may not decide that the warranty is invalid based on knox counter status. People have stated both Ok and void results. YMMV.
Rooting a knox enabled rom can be tricky but doable as long as you follow the processes outlined in the guides.
Me personally, odin flashing the wifi patch (and modem) was by far preferable. Both can be found in the Tmo gn2 forum right here in river city.
Having said all that, some quality time reading and deciding what is important for you personally will take you far with this device. It really is a great phone and extremely capable.
Best of luck to you.

[Q] Need wifi help AT&T S3

Ok, so I've had wifi issues for awhile with this thing, but apparently the 4.3 update sent it over the edge. (I just updated it last week, since I was out of the country when the update issued).
The issue is, I cannot connect to any wifi, other than my home. Before the update, I could connect to non-home wifi only through various router setting changes, that required admin access to the router. After the update, no matter what I've tried with regards to routers, my home router is the only one I can connect to, and the signal strength is pretty bad on my phone, while it shows very strongly for any other device.
I've tried all the suggestions in just about every thread I could find. I've done several factory resets, I've tried the *#0011# thing. I've tried using static IP addresses. But the phone will do one of two things. After I click connect, after selecting a network, it will say Saved. Or it will try to connect and then go back to Saved, or eventually give the Authentication error.
I'm not 100% familiar with how android is setup, but is there a specific file that I could try to install that might affect this? (Like a driver)
Would replacing the antenna be helpful, or maybe the chip on the mb? Or are those options too extreme?
Any ideas are appreciated.

Nobody has any ideas for me?
Please, I'll try anything.

Still looking for help. Thanks!

Did you try re flashing the firmware? Might be a bug in the software. You'll lose all your data but its worth a shot. I've seen a similar issue like this before on the S III and that took care of the problem.

Yes, you will use Odin to complete this process.
Few things you should consider though, by doing this it will completely reset your phone to a point as if you just un-boxed it (or a factory reset). I am uncertain about the fact that it may hinder you the ability to receive further OTA updates. Like i said I don't know exactly on that one but that will most likely be stated in a thread that you receive the firmware from. Also, this may be a good opportunity for you to root your phone if it was not previously. Doing this could be as simple as downloading one file vs. another to use in Odin. The choice is yours as there are threads regarding both Stock Rooted and Stock non rooted firmwares. Another thing, consider which version you want. Im guessing 4.3? I was once told going down a version on android (i.e. 4.4 to 4.2) could brick a device... also unclear on that. try doing some research if you wish.

If you have the AT&T 4.3 bootloader on your phone, do not use Odin to try and flash any stock ROMs as this may brick your phone. The 4.3 bootloader cannot be downgraded and attempts to do so with probably brick your phone.
Boot into download mode and tell us what it says on the download screen.

[Q] Note 3 User - Moving to LG G3 - Please Help?

Dear LG Friends,
Long time XDA member, coming from the Windows Phone days HTC, then to Android HTC, bunch of Samsungs, and am now thinking about the LG space. More specifically moving from the Note 3 (T-Mobile US) running on the AT&T US, to the LG G3.
Before I do, I need some help from you guys. Which variant should I go for? I know my primary choices will be the T-Mobile and the AT&T variants (I believe they are 851 and 850)? Based on what's important to me, below, can you guys advise which variant to get?:
1. Development Support - Which variant has the MOST amount of Custom ROM options, that is on-going and kept current? I am spoiled with the Note 3, which has a massive development support. I have never tried the LG OS/Skin (escaping me what it's called), but if it's anything like the TouchWiz on Samsungs, I think it will be important to have CM/AOSP/AOKP and etc support.
2. This is related to # 1 - But I heard that only T-Mobile has the unlocked Bootloader? However, doing some research, I believe the AT&T and the Verizon and Sprint variants can also be unlocked? Is this true? If so, are they anymore limited than the factory unlocked T-Mobile variant?
3. LTE bands - I will most likely be using the phone on AT&T US, but if development options/support are higher on other variants, I might consider buying those models, even if they are missing some AT&T bands. For the Note 3 - T-Mobile is a Pentaband phone, meaning it had all the bands needed, so it could easily work on AT&T LTE, all the time. The reverse was not true.
And basically that is it. Initial instinct says to go chase the T-Mobile variant, based on my needs above. But please educate me and help me out if I have missed something. Thank you so much in advance!

Any input guys?

If you want OTA updates i suggest sticking with the AT&T variant since you have a valid AT&T sim. If you use a AT&T sim in a T-Mobile variant you wont ever get OTA updates and that means missing out on necessary fixes
1. All 3 US Variants are mostly the same, all have CM12 and all the random obscure AOSP roms as well
2. Well unlocked bootloader isnt that fancy it just means theres fastboot mode compared with the other editions where fastboot mode doesnt work properly even if you enable it. It essentially just makes installing TWRP easier since you dont have to root before installing it unlike other variants
Nevertheless Lollipop can be rooted on all US Variants right now really easily. But the only downside to it is that removing custom roms sometimes can be a pain since you have to use a way where it sometimes works and sometimes doesnt

Hi Friend,
Thanks for your response, this is very helpful!
No OTA is never a thing I consider. Everything that matters to me, is what I listed already.
So, is the development support (new ROMs, updates and etc) the same for all US variants or would you say one variant is particularly more popular?
As for the locked bootloader, I thought you needed an Unlocked bootloader to flash Custom ROMs, no? It seems like "Bump" fixes this for Verizon, Sprint, and AT&T and gets you TWRP on your phone, but do we need to do extra steps everything to the boot.img for non T-Mobile variants? Or is it a one time mod and then regular flashing and Backups with TWRP?
If it's the same for all variants after Bump, then you're right, I will likely stay with an AT&T variant, thanks to that Band 7 LTE.
Thank you again for your help, hopefully more can chime in !

No need for any steps. Its just install TWRP and your on your way to installing whatever rom you want
Unlocked bootloader means that the system doesnt security (consistency) checks on system partitions
For LG G3, its because someone cracked the encryption for the kitkat android bootloader which means people can sign non stock boot.img without having to worry about unlocking the bootloader.

Gotcha, thanks again mate! Another (hopefully last) question. If I buy G3, where someone had already OTA'd to 5.0+, will I still be able to root it, install TWRP and get KK ROMs, like CM11 or something?
And vice versa, if the phone comes with KK, do I need to patch with Bump and then I can install ROMs?

You can root it but i dont know if installing TWRP will work. I didnt want to try it incase it doesnt work and it runs the factory reset script instead. That happened to me once before
But i would say just to be sure, downgrade back to KitKat to do it
Yeah, if the phone comes with KitKat just root, install TWRP using root permissions and then your on your way

This is helpful, once again bud. So how would I downgrade back to KK? Would I have to run a stock firmware of some sort? In Samsung, he Flash a .Tar file through their flashing tool called the Odin. Would that be similarly done here?

AT&T Galaxy Note 4 N910A 5.1.1 Root for CM?

Hey,
Still a bit of a noob to the whole rooting process and navigating XDA forums, so I'm having trouble finding the information *I think* I should be looking for. Basically, my phone's just begun crashing periodically, multiple times a day: anything from Camera, Process System, Touchwiz Home Launcher, or Samsung Apps have "stopped working" / "not responding" before. Of course, my phone's warranty has expired, but my contract isn't up so an AT&T Store wont re-image it for me :crying:
Even I can tell, at this point, that it's either my OS that's failing, or it's my hardware. I figured the easiest way to test this would be to put some stable CyanogenMod on it.
The information I'm looking for is: "is this possible?"
AT&T Samsung Galaxy Note 4
SM N910A UCU2DOI2
Currently @ 5.1.1
Thanks for reading,
~Vita.

No it is NOT possible to use any form of custom firmware or to root this device. It has a locked bootloader that has yet to be cracked open and the future of that happening os very bleak to non existant.
As for reimaging the device go to the note 4 at&t general section on the forum and read up on using odin and the 5.1.1 image posted there it will wipe the phone and format yhe system and data partitions and reinstall it like a new phone just like at&t would do or the manufacturer if you sent it to them.
Good luck

Thanks for the response.
Sorry for the dumb question, but isn't Odin able to flash any firmware onto a device? The "locked bootloader" means that only the stock OS may be reinstalled? Why is this...
Also, it seems unlock progress is being made on the N910V. Maybe hope?
Thanks for mentioning Odin, I'll try re-imaging the phone.

Well the problem is the kernel the bootloader prevents the devs from using an unsecure kernel (one not created and signed by at&t) on the phone if one is used the phone stops boot and says it is an unsecure non at&t kernel and to take thenphone to at&t store.
Odin can only write the firmware versiom that is currently on this phone in this case it is 5.1.1 if you flash any other note 4 versoin such as 4.2.2 it will brick.
Sm-910a flash example
Update ver Official at&t 5.1.1 / currently on phone 5.0.1 or 5.1.1 = good
Update ver (downgrade)oficcial at&t 4.2.2 / currently on phone 5.0.1 or 5.1.1 = brick not good or odin fail
Update from another carrier such as tmobile or verizon for 910t 910v 910g = fail (do not attempt)
Until oir boot loader is unlocked there is nothing we can do to mod or use custom firmware on this phone any attempt leads to a brick requiring using odin to re-flash the latest firmware (5.1.1 at this time) in order to make the phone functional again.

So from what I understand, I could use Odin to flash the 4 files which correspond to the specific AT&T 5.1.1 SM-901A version of my phone (which is exactly what I have) to re-image the device and make it functional again. The problem is, I cannot find these devices on sammobile D:
Could someone direct me to these files? Or are they not out because AT&T sucks? Or, what.

I think so, I don't know for sure but we've been able to Odin from various 5.0 Lollipop releases back to KitKat so should be fine.

downgrading from 5.1.1 or 5.0.1 to kitkat is possible but with many many problem but form 5.1.1 to 5.0.1 i don't know maybe phone will stuck or boot loop
thanks finitetime for your reply

I am sure that you are referring to a sim unlock. A sim unlock and unlocked bootloader are two completely different entities. To flash a custom rom you will need to have your bootloader unlocked, which is something that a few of us are currently working on. Until then, no custom roms can be flashed on the att variant Note 4s. Take care

the boot loader says Qualcom secure boot : disabled ?

Sorry, was off the forum for the weekend. Spexwood was correct, that is sim unlock. Qualcom is for the sim IE network. Take care.

Root is possible if youre willing to dedicate 10-30 hours of repititive root fails

How?
