How to undo a firmware update?

Hello,
6 days ago I got a software update (about 12MB). After that my internet (3G) has been horrible. I checked with another note2 owner on my same network and he also has the same problem. Was that update a radio update? If so how do I undo it. I'm not rooted (and would really like to stay that way).
My current versions are:
Android: 4.1.2
Baseband: N7100XXDLK7
Kernel:3.031-679347
Any help would be highly appreciated.

I would highly recommend you to not downgrade because there is a high vulnerability of sds in that case.

The SDS upgrade was the big one (Over 120MB) also updated to the new OS. This 13MB update I'm talking about I got only last week. Its a small update, I don't know what it was supposed to update, but it totally fAcked my radio I think.

Then you'll need to flash an older firmware.
Flash any firmware for your country but make sure it is dll7 or later.

Will I lose all data? That's the reason I don't want to root also.
Do I do this with Kies method?
What is my country, I bought the phone from the Netherlands.

Download the update you want to go back to and flash it with Odin. You won't lose data.
The update you got was DMA6. If you want to go back to DLL7 just flash it.
Here's the download link for it.

Thanks Yahyoh, can you point me out to a thread that has those? Also can you recommend a modem for Zain KW? The previous modem was fine, but I am not sure what version it was.

[Q] Upgrading a rooted M919UVUAMDB

I'm rooted with a custom recovery running M919UVUAMDB.
So if i get it right. Only way to upgrade is to
Odin to stock.
Upgrade and break root.
Root with upgrade.
Re Flash upgraded stock.

Pretty much. Or you can use Skies to do recovery to the lastest firmware, then root again.

Been searching for last hour or two and this is only thread I've found this specific topic. Just got S4 today coming from a GNex so somethings are new to me.
Is there a detailed instructions somewhere on how to do this?
I'm also rooted on M919UVUAMDB and trying to figure out the best way to upgrade to MDL so that I can re-root again.

Install Kies. Under Tools setting, select recovery and put your phone to download mode. Let Kies do the rest.

Thanks for clarifying. Just to double check, would cwm recovery affect the kies firmware recovery process?

No. Kies would wipe it off during recovery process and install the latest firmware.

lol I've searched around too, but made my own conclusions. ahha

Not attempting to promote any particular roms but Wicked v2 is running mdl update with the mdb modem and radio and smoother than silk on s4, Revolt requires manualy updating with setuidremoval but has a great writeup how to do so as does Infamous S4, I personally can confirm Revolt and Wicked are working flawless as long as the minimal theming currently in both is fine with you.

Going to stock/unroot

How can I unroot my samsung galaxy s3 AT&T phone that is running 4.3 stock mod rom

Depending on what bootloader you have it might be possible through mobile Odin. I would double check before doing anything. I was able to do so recently via mobile odin. I downloaded the stock firmware which you will find on these forums and flashed.

you where on stock 4.3 if I understand correctly whit Knox and the you flashed the stock 4.3 trought odin and it work?

Of course it didn't work, because there is no stock 4.3 to flash though Odin. AT&T never released the firmware.

4.3 downgrade

well. they said it could not be done. but i did it. i downgraded from 4.3 to 4.1.2. and so far everything is working. i used mobile odin pro. loaded the stock 4.1.2 rom but loaded the modem from 4.3. i have a working phone, sound and network.lets see how long it will work for.
and just let me add virgin s3 sgh-i747m

As far as I am aware it was never said this was not possible with mobile ODIN. Desktop ODIN is the issue because it attempts to downgrade the bootloader which is what bricks the phone. You can bypass the bootloader with mobile ODIN so therefore no bricking.

this is correct.

well maybe someone should post a thread about it. like i did. not something that is 377 pages long and a noob like me wont understand. keep it simple. basic directions and links to downloads. its good that you showed a link to how to use mobile oden. but some people don't understand half this stuff. i'm still learning the basics but could not take 4.3 any longer so i took a chance. bricked my phone 20 times trying different stuff and posted what i finally got to work so others can find it easier.

So i can flash 4.1.2 but without downgrading my bootloaders right? Where can i found a 4.1.2 stock rom without bootloader? Or better yet how about 4.1.1? Is it possible to flash this versions without changing my MJB bootloader?? Good thread by the way

i found some of my files here...
http://forum.xda-developers.com/showthread.php?t=1739426
and the rest i downloaded from sammobile
the way i did it is i loaded the old stock file 4.1.1 or 4.1.2 in mobile odin but i loaded the modem file from the 4.3 that i got from link above. it will not change your bootloader but will give you a mix of 4.1.1 and 4.3. make sure you also select to root devise well updating. and use mobile oden pro. it's well worth the $5.00. it took me all of 2 min. fyi you have to load both roms to your sd card on the phone. and back up your phone first. it wiped mine when i did it.

i don't guarantee anything. but this was the only thing that didn't brick my phone.

just make sure your phone is rooted first. i downloaded the root66 4.3 on my phone with odin then copied it as well as the stock 4.1.2 to my sd card.

How do i flash it? My only choices are Odin and download mode.

You may need to do a factory reset. Then Odin. If no custom rom, factory reset will put u back to stock.

Does Odin have a option to do a full wipe/factory reset?
That may be the only option.
He must have used the wrong root script, like AT&T or Sprint root.

You need either 4.3 or 4.4.2, MDL is 4.2.2, it'll never flash, so flash 4.3 or 4.4.2, you can only flash 4.3 if you had that firmware before you attempted to root, if you had the latest update you need 4.4.2!!

How did you manage to get it to 4.2? As far as I know downgrading from official 4.4 firmware WILL brick your phone. There's no way around it. I'm very curious to know how you did it! Thanks in advance!

When I was in 4.4.2 I wanted to root it (of course) but I used the wrong baseband version/file so it messed up. Then it gave me like some type of warning saying (SEANDROID EFORCING) Warranty Bit: Kernel
I told my bro to fox it and he did, idk how he did it but he did. I search up on youtube SEANDROID EFORCING and I guess thats how he managed to save my phone.

That's what happens when you flash a 4.2.2 ROM which you can still do.. that SEANDROID message doesn't prevent anything so there is nothing to bypass.. If you're ok with 4.2.2 then I guess you're good but personally I would prefer to be at least on 4.3.. All you have to do is follow my previous directions
