[Q] How do I go from ME7 to MJ7? - Verizon Samsung Galaxy S 4

Hi guys, I'm currently running a Hyperdrive RLS10 ROM, but I'm looking into the future with the new KitKat release, and I was interested in trying some of those features when sbreen updates his Hyperdrive ROM. Thing is, I'm a Verizon ME7 user with an MDK phone, and I have no idea how to take advantage of these new features, as from what I read so far, a simple reflash won't work. Can someone tell me exactly what I have to do to get from ME7 to MJ7 and still have my app data and messages? The rest I could reconfigure but I really need to keep the app data.
I've read things about having to ODIN back to stock, and whatnot, but won't that technically kill all the stuff on my phone with no recovery? :/
EDIT: after a bit of looking I'm reading that since I have an MDK phone it's actually fairly valuable for this, but I don't get exactly what for.

Because you can flash ROMs via TWRP.
MDK has the LOKI exploit available with a bootloader that can be bypassed or hijacked.
Look in the ROM area.
You will find what you need.
There are ROMs based on MJ7 4.3 that won't screw up your phone.
You just need TWRP.

Will I need to ODIN or any of that though? And Hyperdrive is at the moment based on 4.3 MJ7 so all I need to do is have TWRP and then I can just flash RLS12 onto my phone like a regular ROM installation?

what recovery do have loaded and how did you flash HD10? You would flash any custom rom the same way. As long as you haven't taken any OTAs or odin'd a higher level firmware you should be good to go

Worth upgrading from MDK to ME7?

Hey guys I am currently rooted and unlocked on MDK running Bone Stock ROM. I am running the ME7 Radio.
Is it worth updating to ME7 and using Safestrap (I haven't read up on Safestrap yet so not even sure what is is)??

If youre on mdk you might as well stay if your wanting to run custom roms. Safestrap hijacks the boot process and boots a custom version of twrp recovery. Safestrap can only allocate so much space for each custom rom slot. 3gb being the largest. If youre wanting the features of me7 there is quite a few custom roms that use an me7 base.

Yea I figured it would be best to just stay on the MDK base. I was planning on reading the Safestrap thread, but either way wanted the opinion of others. Thanks!
I don't have an SD Card yet either...so I technically can't update to ME7 and be rooted...although I do plan on getting an SD Card eventually

I think you answered the question I am trying to research. I can flash an me7 based rom as I am currently stock mdk with twrp. I was afraid I would have to update to me7, reroot and install safestrap - which I'm not terribly interested in doing at the moment. I'm kinda waiting for modaco switch before I start custom rom'ing but found out about it too late to be a guinea pig.

Yep thats entirely possible. Theyre based off me7 but dont have the disadvantages of me7 such as the blocked loki exploit. Im currently running the stock root deodex of me7 so im still able to flash custom roms if I like. Great battery life and very stable. I dont have smart view or pip as im using the stock kernel but I dont use either of em anyway. However flashing a custom kernel fixes it.

ive seen that thread it says if you have mdk do not take that update, im looking for a stock rom if there will be one available,
thanks for the help
Don't take any OTA or flash anything in Odin except MDK. Just give the devs time to update their Roms Then flash as normal. 4.3 just dropped they will update just hang in there. And there will be stock Roms available.
A good choice if you like the stock feel. http://forum.xda-developers.com/showthread.php?t=2384362

[Q] System software not authorized HELP!!!,

I updated from ME7 to MJ7 with success than I flashed philz recovery with the root tools app and got the message
Secure fail: kernel
" system software not authorized by verizon wireless has been found on your phone. Please turn off your phone and go to the nearest verizon wireless store for help."
After I managed to boot back into my stock rooted phone and flashed CWM from rom manager and with no luck got the same message.
What do you think I should do? I really don't want to have to Odin back to stock and root with root de la Vegas again.
Discard when upgrading is very dangerous. You may have to Odin back to stock and root de la Vegas again
is your phone originally mdk base and you are loki'd? if not, the ONLY recovery available is safestrap. You will have to ODIN your phone and do some reading

My phone was loki'd and than I updated and must of lost it so I guess I'm going to have to use safestrap?

if you took the update, you are screwed with custom recovery except for safestrap
So if I have safestrap I have to have a backup of the stock rom right? Or can I just install a custom rom and get rid of the stock rom?

Read the Safestrap threads. The answers to your questions are complicated, particularly the "get rid of the stock rom" since that's possible but risky.
YOU will need to judge whether or not you will take that risk based on understanding how Safestrap works.

Always back up the stock rom.
Like he said read up.
It gets complicated. I'm running Hyperdrive on my stock slot but there are risks.

to me the risks of losing the stock rom isn't worth it...especially if all this is new to you. You can always go back in the future and do i

You're definitely right there. I had to play the Odin game myself and I think for the time being HD11 is going to serve as my stock and I'm going to use Rom slots from now on.

MDK & 4.4.2 question

Greetings,
I have an S4 with MDK and it is currently running a Hyperdrive ROM. I want to upgrade it to a KK ROM of some flavor. I put SS on, thinking I would need it, but it looks like SS makes it more difficult? I believe that because the bootloader is locked, I can't just install a plain version of TWRP, correct?
So, for those with MDK who are now running KK, what did you do, what did you use, and in what order?
Thank you!

So if you're on MDK with a custom rom then what recovery are you using?
The MDK bootloader has a loki exploit so you can just use a loki'd version of TWRP or CWM to flash any 4.4 rom. Find them in the original android development section

If you are still on MDK the go to this section http://forum.xda-developers.com/galaxy-s4-verizon/orig-development and look for a 4.4 you would like. I believe Sbreen has a 4.4 of Hyperdrive in the works right now so if you like Hyperdrive, wait maybe if you want to?
Your post confuses me a little. If you updated the phone off of MDK and now on another baseband now then you will have to use SS and follow the instructions on how to go to 4.4 and back to 4.2 if you have to. Here is a link if you are on NC2/MK2 http://forum.xda-developers.com/showthread.php?t=2726868.
If you have NC2/MK2/MI1/ME7 then you CAN NOT have a Custom Recovery like TWRP or CWM. You will have to use SS and go from there.

Best possible path for me to upgrade firmware? Love to hear what you guys think.

Hi! before anything else, let me get this out of the way so you know my situation:
Verizon GS4 SCHi545
version: 4.2.2
baseband: ME7
Safestrap Installed, Jelly beans build 7 installed
Now, as far as I can tell there still is no unlock for the bootloader (i think MDK was the last unlocked baseband?), so I'm wondering if there's any way that I can keep root and upgrade to 4.4 or something higher, because I'm a little tired of being told I can't use 4.4 apps, and plus I would REALLY like to get off of touchwiz if I can. Basically, I'm getting a little sick of where I've been at for so long with this phone, and I'm looking for recommendations for things I could do, if there even is something.
Thanks guys!
You definitely can upgrade and keep root all the way to LP 5.0.1 (or OC1). Look in the development section for ROMs that are Safestrap compatible. Do not use roms for MDK as this will softbrick your phone. DO NOT TAKE THE OTA UPDATES TO UPGRADE AS YOU COULD GET STUCK WITH OC1 BOOTLOADER AND NO ROOT. Upgrade yourself using safestrap, just remember to flash the current SU.zip file after the ROM.zip to retain root. As long as your bootloader is below OC1 you can always use Odin to restore to NC5 and then root and go from there.
As far as getting away from TW - well good luck. Being on ME7 you are stuck with a nonMDK bootloader and must flash ROMs through Safestrap. All of the ROMs for Safestrap are TW based.
There are numerous tutorials and ROMs in the development section. Look for the Safestrap compatible ones. FOLLOW THE INSTRUCTIONS TO THE "T". DO NOT DEVIATE. For 4.4 I prefer Hyperdrive 21. Great ROM with loads of customizations.

make sure you read before flashing if you do it incorrectly you will lose root/bootloader unlocked status PERMANENTLY
can i use this method to update, even though I'm not going from NC2 or MK2? cause me7 is below the two of them right?
