So you flashed the modem to one of the slots, and not the stock rom correct? This keeps the stock rom on mf3, thus not breaking safestrap, but also allows us to use 4.3 based roms on one of the other slots?

I Did slot 1 (Omega Rom) just to be on the safe side

So you are on SS and locked bootloader correct? And you were able to flash a 4.3 rom? Every time I try to install a 4.3 rom it boots into a black screen with the notification light on. So does this fix that?
Thanks

No, he only flashed the modem. Its a kernel thing. SS really hijacks the system after boot loader . Hopefully someone can come elaborate.

I haven't tried since this flash became available. I tried a few weeks ago and it never booted on 4.3. I was asking if this flash fixed that issue.

Interesting. I may try it out. I've been wanting to use some of the 4.3 roms out there, but I feel like I'll shoot myself if I mess up the ability to use safestrap and flash lol.

Easton999GS · Oct 25, 2013

Oh my god... if anyone here is on safestrap, The radio is seperate from the rom entirely. We can flash these on safestrap however we want. We cant run any 4.3 roms because we dont have signed 4.3 kernel. Unless we can get kexec which redirects the kernel to a custom one or a bootloader unlock where the kernel doesnt need to be signed we are going to be stuck with the 4.2.2 MF3 kernel. Our only other choice is to upgrade to 4.3 and hope to god that there is root and that safestrap isnt fully patched. But im going to stay on 4.2.2. The 4.3 bootloader is hell on earth and tighter than fort knox. SELinux is set to enforcing?? no way. Right now MF3 is the last bootloader for any hope in getting kexec and a bootloader unlock somehow because Sammy just stepped their game up big time.

Venom0642 · Oct 25, 2013

Nice to bad no one has made the Stock Kernel for 4.3 yet!

Easton999GS · Oct 25, 2013

This modem ****s on my battery life. I have a theory that the bootloader and the radio talk to each other, Ive been through about 5 galaxy s4 phones due to different issues and ive had all of them rooted. With the MDL bootloader if I flash MF3 radios the battery life sucked but if I stayed on MDL radios it was amazing. Now on this replacement phone im stuck with mf3, If I flash MDL radios the battery life is trash but on MF3 its actually amazing. So with these new radios and the old MF3 bootloader I feel like this issue is reoccurring again. I have a friend with VZW who is on MDK who notices the same thing as I do when he flashed the ME7 radios.

Thanks to Design Gears for his leaked MJ6 4.3 ATT Firmware.

I extracted the modem and put it into a flashable zip to be used in cwm/twrp recoveries.

EDIT: I flashed it on Vision MJ5 Rom Firmware version 4.3 and so far so good. Then I flashed back to MF3 firmware ROM ShoStock 4.2.2 and flashed it and it worked on 4.2.2 as well.

Thanks bro its working on GE4.2.2 via safe strap. It does not work with the darthstalker rom tho.

I flashed this and the reception is good. Not much of a difference but the gps is very inconsistent. Even after it finds my location it will continue to blink and has a hard time keeping track of where I am on the road... I use the gps alot so this is a problem.. I'm going to have go back to mf3

Going to give this a shot on GoldenEye 9.1 tonight as well as CM10.2. See how it goes.

I have a flashable MF3 modem, Can I flash back if I have issues?

Yes you can flash back. I have done it multiple times. I am on TW based Roms though IN CASE that matters. But I believe others have flashed on cm based Roms with no issues.

I flashed this in safestrap on a different ROM slot than went to my stock ROM slot and saw I had this modem on. I tried flashing the mf3 modem on my stock ROM slot and its still on the mj6. I mean its not messing anything up right now and the official release is going to be out soon so I guess I'll stick to this unless something happen.

That's not surprising at all. The modern is not unique to which rom you're on. It's unique to the phone. And once your on mj6 modem I'd be surprised if you could go back

Well people have been saying they're going to go back to the mf3 modem. Only two ways I know to go back to mf3 modem would to flash the zip in SS which I did or erase everything off your phone and go back to factory stock settings than go through the hassle of setting up things again.
