4.3 mk2 or mj9 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey everyone. What will the baseband version be for 4.3? I see people saying its I337UCUEMK2 and I see others say its I337UCUEMJ9. Which one is it?? Its driving me nuts... I'm trying to look and see if people already have a root option for 4.3 for the gs4 and I need to know whether to search for MK2 or MJ9. If anyone could tell me which one that would be great. Thank you in advance. Much appreciated!

He means a ROM he could flash without losing the exploit, not the actual update.
Just wait and one should be created like it was for MF3, otherwise you'll have to settle for any other 4.3 ROM. You could always check the international section for their stock 4.3 or something.
I hope someone will create one

In the mean time you could try this. It's based on mj9. http://forum.xda-developers.com/showthread.php?p=42294395

can i go back to 4.2.2 from 4.3?

hey guys... im on 4.3 MK2 rooted, can i install a 4.2.2 rom stock or custom ?? with 4.2.2 modem and bootloader.
thanks.
If you updated by keeping the MF9 bootloader you can go back to stock. If you took the OTA however, you can only downgrade to 4.2 with a custom ROM.

but i can downgrade to 4.2 (100% 4.2) using a custom rom?? or i will be on 4.2 but with the same new bootloader?
what custom rom would work in my case? if you can give me a link to one.. there are so many here.
If you're on the MJA or MK2 bootloader, you're stuck with it.
And why would you want to go back to 4.2? Any ROM would work, but seems kind of pointless.

i downgraded the modem to mdc and did the unlock process. it worked, i can make and receive calls but when the phone is going to 3g i get a error message "LTE esm 29 emm-x cannot establish wireless data connection" nobody else had that issue.. i dont know if hte fact that my phone is not activated on spring is relevant.. it shouldn't be, because im using the phone outside the US.
i dont know what to do to make this thing work.. i have flashed from mdc to mk2 or mja like 5 times and i always get the same message.

About to buy (another) S4 tonight, please help!

Hey guys, well I'm back in action! After dumping my S4 a few months ago, I am getting another one tonight. Ever since I saw the 4.3 update on my gf's S4, I saw that things have smoothed out and things are the way they should be!
Long story short, I want to see if the one I'm getting can be rooted. It is on 4.2.2 and the baseband is I3373CUFCMF3. Am I good to root it? I've been out of the S4 game for a while, so I don't know. If I can root it, can I run 4.3?
Any help would be appreciated, thanks!
I'd try to get a MDL one so you could just flash a 4.3 custom ron

Most, if not all current S4's will have MF3 firmware preinstalled. I doubt any store would have MDL firmware. Those devices would have had to be sitting there since early summer.

Yes, with MF3 you can root. You can then install safestrap and do some roms.
However if you take the 4.3 update you lose the ability to safestrap and use some roms, but you should still be able to root. I am not 100% as I just kept mf3 and put a 4.2.2 rom on it.
Ok, thanks for the responses. Can I flash any ROM with Safestrap or just some? Can I flash a custom 4.3 ROM for example?
Thanks!
You cannot install anything that's not touchwiz and anything above 4.2.2

Your very limited with roms using safestrap. Even then, the ones that work, might not work all the way. If you had MDL, you could use any rom if you flash loki-doki.
Just ask if they have one with MDL firmware. Doesn't hurt to ask, right?
Thanks for the responses guys! I will see if I can get a hold of a MDL phone.

Get a device that isn't as locked down as the s4 or note 3. Maybe nexus 5? Unless you can live with safestrap or just root. Which I can. If your a ROM flashaholic than stay away.

Thank you for the reply.
I've searched the general forum, but I'm having trouble sifting through all the information.
Have you ever updated your firmware for a rooted phone?
I understand how to use Odin, but I need a tutorial.
I'll look again.
?...
I'm still not sure what to do, I really want to experience the most out of my rooted phone.
I'd like the newest advancements...
How bout this question, anyone reading this have my phone type and what did you do with your phone?
