[Q] Canadian MDJ firmware vs MDL ROM

I currently have a brand new Canadian S4 with the MDJ firmware/baseband version.
Most of the roms are MDL based.
Do i have to change the base firmware/baseband to MDL before flashing and MDL rom ?
My goad is to install CleanRom wich is MDL based.
Thanks for the guidance.

You can just flash the ROM. Just make a Nandroid backup first. Some ROM's come with a custom kernel and you may need to flash a Canadian kernel directly after flashing the ROM.

I did get the original Kernel file for my cell provider. It is a TAR file with boot.img into it.
What is the easyest way to apply it after flashing the Rom in TWRP ?
Thanks

TARs are flashed with Odin or Mobile Odin.

If you are flashing the STOCK firmware for your specific carrier it will include the STOCK kernel.
If you are using a custom ROM like Mint Jelly or something, I'd say flash Adam kernel after flashing the ROM. You won't want to flash a STOCK kernel with a custom ROM.

Did you end up updating to MDL?
I also have the MDJ kernel and I installed CleanRom, I now cannot get wifi and TWRP will not boot in recovery mode. I thought it would be easier just to update to MDL to get wifi but mobile Odin did not work.
Thank you

Regarding wifi on CleanROM, did you check post #2 here?

No I did not,
Truthfully I am a pretty big Noob to all of this and was afraid of changing my kernel to MF3 from MDJ. I really didn't know how that would affect my phone / carrier situation here in Canada. The main problem was that I could not get the phone into recovery mode. Turns out I just needed to re-root the phone. So when I got the phone to actually go into recovery I jumped at the CM Rom. When I find a forum that helps me understand what updating my Kernel does to my phone I will try to update Kernel and go back to CleanRom. I kind of miss multiwindow.... maybe a little bit of Touchwiz...
Thanks for the reply!
EDIT : I also found this : http://www.scottsroms.com/downloads.php?do=file&id=421 which is a version of CleanROM made for the MDJ but it is dated further back which threw me for a loop too.

No worries and you're very welcome! Don't sweat, I'm still on stock ROM because I'm hesitant to make the ROM dive. Don't know how or if installing MF3 kernel via custom ROM would affect the phone in terms of rooting or custom recovery either. I'd probably be sticking with MDJ build if possible.
You and me both on multiwindow! Helps a ton when it comes to referencing something while emailing/texting! I'd miss the TW camera as well ... maybe. haha
Which version of TWRP are you on? Version 2.6 has an often-experienced issue where it just hangs at the "teamwin" splash screen. Downgrading to 2.5.0.2 resolves that.

Any updates?

Hey guys,
I am also a 1337m Rogers S4 (MDJ) owner, also a noob as well. I managed to flash my phone with CM and had a pretty good AOSP experience and learned a little bit on the way. I can legitimately say that I miss a couple thing about stock / Touch wiz, mainly the multiwindow support and camera. Cyanogenmod is also acting up and drains battery pretty bad when I am roaming in the states.
What did you guys end up doing? Did you update your base-band to mdk and install CleanRom? Right now that looks like it's my goal but I truthfully have no idea how to do it.
Did you guys go back to stock after changing? Do I just find a stock ROM on the forum and use ODIN to bring it back?
Is switching roms as easy as choosing something in Goo manager or do you need to go into a recovery in recovery mode?
Thank you!

Will Samsung Galaxy S4 I9505 converted to GE get OTA?

If you flash the Platform + CSC file from the Odin firmware, yes.
But everyone must stay stock (kernel,recovery etc)

so: if google plans rollout to GE edition phone for official release 4.3 of KLP you will receive it also on your standard I9505?
i dont get why this is? thats why there are nexus phone but other phones that you flash like this wont get the ota like a nexus?

Because we are using the exact same I9505G system,kernel,csc,recovery and its official firmware so thats why.

How does this differ from say flashing the stock rom zip and a stock recovery? That way, you'd be on the stock odexed rom, with the stock kernel and the default CSC. No hassling with Odin.

So does that mean we will be able to get the OTA Updates and have a 100% GE S4?
Because my Father would really like the Google Edition S4 but he already got the Standard one and he doesn't know ANYTHING about flashing but if it would be possible to flash he could get the OTA Updates.

OTA will brick your phone atm because the bootloader can't be flashed from the GE on the 9505

so installing the android 4.2.2 google edition (not 4.3 because it is not possible with odin) you still wont receive OTA updates?

Usually ota updates doesn't flash bootloader unless there's a bootloader update ofc. So you can get updates but it's recommended to not do ota updates for your phone. Specially not when it can brick your device but it's you're choice if you want to

wrapping my head around GE
Sorry for the noobness;
I have an i9505; ever since it was announced, I was looking forward to flashing my i9505 into a GE.
Some initial roms have appeared. I just wanted to better understand some of the terms thrown around to make an informed decision;
The ROM seems to be pretty similar between all those who have thrown their hat into the ring: jamal2367, janjan, samuel2607, Hazanwar, m3dd0g, and maybe a few others. Is there any major difference between these ROMs? Q: Should all these ROMs be identical? They all have the same origin, and all are trying to go for the pure/vanilla GE experience
I think each of the ROM modders are using different kernels, or kernels slightly modified. Again; what is the official kernel for GE? is the "stock kernel" for GE the same "stock kernel" for all S4 i9505? My device is Model number SGH-I337M; Kernel v3.4.0-518267; is this the GE kernel? I know kernels can be tweaked to overclock or undervolt a phone, getting performance or better battery, respectively. I'm trying to turn my i9505 into a GE clone. Which kernel should I be looking for?
Some people have mentioned CSC. This is where I'm completely lost. From what I understand, CSC is the way phone manufacturers classify and differentiate phones model for specific countries and specific carriers. Is this correct?
Either way; how does CSC help or hurt my goal of emulating fully a GE phone? Would I need to change the currrent CSC in my phone to a second CSC? What would that accomplish?
also; someone has mentioned recovery. Should I interpret that as the bootloader? are these things related, or the actual same thing referred differently? how does the bootloader (and/or) recovery help me clone a i9595GE?

I have a question. Why are there many people working on GE Rom, and there's no actualy GE firmware (without bugs) like TW firmwares to be flashed on the phone?

there are actually pretty stable (at least the 4.2 one) however why they work on it its mostly due to its easier when you get all the libraries for the device to something they've waited for. pure AOSP can be good if you wouldn't miss the features s4 gives.

Flash T-Mo Firmware on AT&T i337

Hello, I've installed tons of custom roms on quite a few different devices before, but this is the first one I've owned with a bootloader that can't be unlocked and I'm still kind of confused as to how all of these workarounds function and what ROMs they're compatible with. I've unlocked the phone and am using it on T-Mobile. It's currently on the MLD KitKat leaked version.
This is possibly wrong, but my understanding is that you are currently unable to install custom ROMs like CM and Omni on this device. So would it be possible to at least flash the stock T-Mobile ROM instead of AT&T? Right now, I have no access to hotspot, which is included in my plan, and I'd also like to use WiFi calling if possible. Has this been done before and is it possible on my firmware?
Thanks in advance for any help; it's greatly appreciated.

You can not flash their stock firmware. You can, however, use Safestrap to flash a ROM from their section, which as long as it is based from the stock firmware will have those features.

I have flashed HYPERDRIVE ROM with T-Mobile compatibility pack and works fine ! Even WiFi calling works!

Thanks, guys. I just got back from a trip and I'll be attempting this now.
Are there any AOSP-type ROMs that will work with this?

Also, if you havent done so, you might want to enable AWS for further compatibility. You will need to use the stock AT&T TW ROM in order to do so.

Since you're using Safestrap, you can't flash a kernel anyways due to the locked bootloader. You should be able to go ahead and flash that.

Flash G928F Firmware on G928T in the US?

Just wanted to task how I would go about getting the right radios for the US while having fresh stock software from the G928F.
Has anyone tried it like this? I haven't heard of people changing the radios back after a full firmware flash yet, and because I haven't done a whole lot of modding on Samsung devices, I just wanted to put it out there.
Thanks!

it may work, but only if you will flash your stock or custom kernel on top

Hi. I want to try it on my G928T. How?
Do I install trwp, G928F firmware and then the stock or custom kernel or how?

Anyone tried this ? My situation is the other way around. I want to flash US firmware on my 928F model to get Samsung Pay support when I move to US. ...

If your bootloader is locked, and I believe it is since the phone is probably running a stock rooted 5.01 ROM, you cannot install a custom recovery which means you cannot flash any custom ROM that is not based on a stock touchwiz ROM.

Can we downgrade to a version before lollipop and flash custom roms ?

Nope, downgrading is not possible. You'll be limited to using safe strap to flash tw based Roms. Cm and aosp Roms are not possible.

No, you can't down grade to anything you could flash a custom recovery to. Look into safestrap.

As in the guide "the keep root method for OK2" clearly stated that the lowest you can downgrade the ATTS4 is kitkat NB1.
Since you are on OK2 bootlaoder and want to install the custom rom I suggest you need to find the OK2 based TW custom rom.
Because the bootloader is locked, you can not install the custom recovery like TWRP. You are stuck with either safestrap or flashfire.
I recommend to use the flashfire since safestrap is too tricky to work with lollipop. With flashfire you can flash tw based custom rom in the lollipop.
