Hey guys
I installed a nightly of CM11 a while ago and it broke my LTE. The consensus is that you need to install a stock-based ROM, then flash back to CM11 to get LTE working again.
I have flashed an MK5 modem, but am unsure of my bootloader compatibility with the current TouchWiz ROM's out there.
I am on the MF1 bootloader (Canadian phone). Do I need to upgrade/downgrade my bootloader to install any of these TW ROM's? Or can I just flash between TW and CM11 to my heart's consent?
The ROM's say you must be running a 4.3 modem and bootloader...but I can't find any info on whether or not MF1 is a 4.3 bootloader or not?
Thanks,
Elliott

I haven't tried cm11 yet but using c-rom I had these problems. under settings-mobile networks-preferred network type, check to see the right network is selected. If you don't have these options then my apologies.

MF1 is 4.1.2. The latest Canadian bootloader is MK5 (Which you can't downgrade from).

Well usually you need the same modem as your bootloaders. Some of them are really picky so having the MK5 might be why your LTE isn't working.
You can grab the stock ROM in the general stickies and flash it with Odin though (make sure to backup) if flashing a 4.1.2 modem doesn't fix it.

Okay. What I'm most concerned about is flashing a 4.3 TW ROM with the bootloader that I have. Is having a bootloader from 4.1.2 a bad thing? Or can I install all ROM's with MF1?

Only the downgrade is dangerous, you can upgrade without any problem. That being said, you could just flash the stock 4.1.2.
And if I flash a stock based ROM will it upgrade my bootloader to one I won't be able to downgrade from?
Any suggestions for ROM's?

It depends which one you decide to flash. You can flash stock 4.1.2 just like you could flash 4.3 (which you can't downgrade from).

Now that 4.3 stock ROM is out, has anyone developed a method to roll back to previous JB stock ROM's?
From what I read, once you update the bootloader, you cannot go back. But surely one of our great developers has/will come up with a method.
Thanks

Would like to know when this comes out too. From what I know it hasn't been done yet. I'm constantly advised to flash a 4.3 ROM if I want to go back to stock but the current 4.3 ROM is way too buggy.

Thanks. So is the "not able to rollback" only related to the bootloader itself? And after upgrading to 4.3 with MJB bootloader, we can return to 4.12 as long as we don 't flash a 4.12 ROM with a bootloader?
Sorry for the questions, but for some reason my brain and the whole bootloader deal is a no-go

Can anybody confirm that if we are on 4.3 stock, and install CWM and non-stock ROM (CM, PA, etc.), will the warranty check flag change to 0x1 in download mode? Or will it remain at 0x0?

It will trip the flag if you flash a recovery. If you're worried about it tripping, don't flash anything. Mine tripped rooting stock with CF-Root. Not a big deal though, only two months left on the contract.

From what I have read wifi won't work without it.
I tried
I flash a 4.2.2 stock rom after OTA updating to 4.3 with a mobile odin. But the baseband and imei became unknown after I boot the phone. So I have to flash back to 4.3 again....LOL
I was able to flash to UCMG2 stock after what I will dub my 4.3 OTA fiasco lol I flashed it in TWRP using the download from this thread http://forum.xda-developers.com/showthread.php?t=2388065
I did not need to flash any other item as everything appears to be functioning well.
Hello, I was originally running a beta version of Panandroid 3.99, and then I flashed a Stock modified Tmobile Rom on 4.3. I wanted to see if I could get wifi calling to work on it and it did, then I wanted go back to Quantum Rom.
For some reason I could not get Quantum Rom to flash, TWRP would read a "unable to .zip or something like that. Then I read I should update my Bootloader and Modem. So I restored an old backup to Cyanogen mod 10.1.2 (4.2.2 Update). I was able to flash my modem to the MJB update, but whenever I tried to flash my bootloader to the MJB update, TWRP and CMW would both give me Status 6 errors.
I am currently on the LK3 modem as stated by my Terminal Emulator.
Any suggestions on what I should do?
I'm also confused on how I was able to flash Panandroid 3.99(4.4.2 KitKat) on the LK3 modem? Should I have needed the MJB modem in the first place?
The bootloader and device ID is normally what determines if a rom can be flashed to a phone, not the modem.
Visit the S3Rx post and scroll down to the download area and you will see the modem and bootloader flashable zips. I would go with the MJ2 bootloader /MJB modem combo to allow you to go backwards in bootloader if needed.
You may need to update TWRP to the latest, I understand that 4.4 roms require the latest.

I think you meant the MG2 bootloader, which did install fine. After that, I was able to flash Quantum and GAPPS.

Glad that fixed the issue. :good:
Actually, I meant MJ2. Interesting enough I now see is not on the boot loader list thread (http://forum.xda-developers.com/showthread.php?t=2321310) and appears to only be found on the custom 4.3 TW roms sites (which references to the S3RX rom thread (http://forum.xda-developers.com/showthread.php?t=2252932).
LK3 - 4.1.1
MG2 - 4.1.2 (OTA)
MJ2 - Leaked 4.3
MJB - Official 4.3 (OTA)(make sure you read the warnings if you go to this boot loader - there is no going backwards)
So unless you need to go to a 4.3 boot loader, which it sounds like you do not, I would stay where you are.
Does someone have a "flashable" zip for the new 4.4 NE4 modem?
Not a good idea at this point. Unless yours already on NE4 firmware it'll brick.
I'm updated to NE4 and want to flash back to a 4.3 rom. I was able to downgrade but unable to get any signal due to not having NE4.
I just need the NE4 to flash to get signal back but not the whole OTA.

Updated via OTA to 4.4.2

This will simply get Wi-Fi working again after restoring a 4.3 backup, after on 4.4.2 OTA?

No it most likely won't fix WiFi, this is only for if you flashed the 4.3 modem as instructed in many 4.3 Rom threads, after having updated to the 4.4.2 firmware.
I believe the wifi issues you are referring to are kernel related. If on a 4.3 rom, flash the MJ2 kernel to fix.
Yeah Wifi is kernel issue. I've had to use the Ktoonez 4.3 kernel if I'm running a 4.3 ROM after updating to the NE4 bootloader.

so I'm currently on 4.4 NE4 bootloader and on an AOSP rom(AOSPA), will I be able to flash 4.3 kernel to fix wifi? I remembered some roms mentioned that 4.4 aosp rom only accept 7/1/14 and up kernels.. but forgot which
The kernel will have to match the rom. So if you're on a 4.4 rom, you'll need the kernel to be the same. Also, aosp/cm kernels are not compatible with touchwiz and vice versa. The MJ2 kernel fix I mentioned previously is only for 4.3 touchwiz roms. Im not sure about what you'd need to do for aosp though.

i've pretty much tried all the 4.4.x kernels and none of them seem to work :3
Probably best to ask in the thread you got your rom in then. I dont use non touchwiz roms so im not well versed with them and their requirements.
Generally, you should use the kernel included or recommended with the rom for troubleshooting.

yeah i know that, but thing is when i flashed the TW 4.4.2 from my previous post, the problem already showed up, I couldn't turn on wifi at all.
which happened to me before in the past and when i flash an AOSP rom, it fixed, so that was what i did, but just that this time it didn't work
and what pain me is that going back to stock will reset everything again...

Yep. Once you update to NE4 then you have to use NE4 modem from then on because the NE4 bootloader will enforce that.
Post #4 on this thread by DocHoliday77 provides a flashable NE4 modem zip that you can flash though CWM or TWRP and get your signal back.
Even if you use a 4.3 rom once you have tried or updated to NE4 bootloader, always flash NE4 modem.

I understand that this is an old thread, but I have recently pulled out my old S3 and see I am on FW Ver. I747UCUEMJB. I have seen the new lollipop roms for the S3 and they suggest flashing the NE4 modem/bootloader. Is this now safe to do? If not how would I go about upgrading my bootloader/modem?
Stupid question here but ... I'm already on NE4 but I Got the phone from a stranger. It works 100% but I don't know if anything was dine and put back or antrhiing. Its absolutely on NE 4. Can I reflash this in Odin without additional risk of bricking the device? I put lollipop on it and would miss it terribly
I am trying to upgrade an S3 from an older kit kat aosp rom to a 5.0+ rom. The phone is still on the UCDMG2 bootloader/baseband combo. I kept it on that version to keep my unlocked bootloader and not worry about all this e-fuse stuff going on.
So here is the problem. 5.0 roms flash ok, but say I have no signal. I am able to make phone calls and send text messages, but I have no data. Is there a modem I can flash that will work on 5.0+ roms with the old bootloader? I have been sifting through the various modem/bootloader threads with no luck. Any suggestions on how to obtain data?

Ok good to know. So once you upgrade, you don't have to unlock the bootloader to flash recovery/rom?
Edit: sorry, dumb question.
After upgrading to the mjb or newer bootloader, you cannot downgrade the bootloader to an older version. Also, the upgraded bootloader will remain unlocked so you can easily flash a custom recovery in Odin.

Can you point me towards the best way to upgrade? I have found some flashable zips, but would prefer to do it through Odin.
I think the safest way to get to the newest bootloader and modem would be to use the 4.1.1 firmware on sammobile.com to flash back to stock in Odin. Once you set up the ROM on your phone, run the OTA updates until you have the latest modem and bootloader. It the slowest way to do but, in my opinion, the safest.
If you phone is not sim unlocked, you can use the free method to permanently unlock the phone while you are on stock 4.1.1.
Once you are on the latest ROM, you could install a custom recovery, create a nandroid backup of the stock ROM, and then flash a custom ROM.

You should run through the free unlock method after you flash back to stock. Even if the phone is already unlocked, it won't re lock.

Do you have a custom recovery installed?
You didn't say, but I can infer that you have an i747 and not an i747M based on the MG2 bootloader.
Without a custom recovery you are stuck using Odin to get a custom recovery in order to flash anything other than a stock rom. There are recovery flashable bootloader and modem files for 4.3 and newer bootloaders and modems.
With the 4.1.2 bootlaoder and modem you could run Jellybean roms from CM ( CM10.x ) or those based on CM or AOSP. There may be a few AOSP bassed on KitKat you could use, but it would probably be a version that is more than a year and a half old. Anything newer will need a 4.4.2 bootloader.
