Yes, with current SS and MF3, can only use stock kernel and 4.2 TW ROMs. I have GPE on my MF3 S4 and have wifi and SMS/MMS on LTE with no problems. Don't use hangouts though so no help there.
[AT&T Samsung Galaxy S 4 Android Development] JohnMonsour:
Elaborate please. Did you flash to a rom slot or to the stock rom slot. Because that is what we are talking about.... Did you flash mf3 modules.zip after? thanks.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
If you're talking to me, I have done both. I initially flashed GPE ROM into my ROM SLOT 1 then flashed MF3 mod afterwards - no problems. Then after Horizun tested it in the stock ROM slot, thats what I now have setup. Again, flashed MF3 mod zip afterwards.
[AT&T Samsung Galaxy S 4 Android Development] norbarb:
Custom lock screen

After i install recovery using last version of SS i get peddlock and custom on splash startup screen. How i can remove it?
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
Did you wipe system before you installed it? I had to do that to get gpe to install correctly..

And if your talking to me, I'm on gpe on stock slot, with modules. Everything is working but usb storage mounting, and hangouts video calls.
[AT&T Samsung Galaxy S 4 Android Development] bsmithvc:
I have a rooted 4.3 will this be available for 4.3. I don't mind waiting just wanna know if it's on the works? Thank for all the hard work!
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
If using tw based rom, get xposed and wanam module. There is a security thing in there to patch that.
[AT&T Samsung Galaxy S 4 Android Development] norbarb:
Which one security it is?
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
In the Wanam app once installed and activated, scroll to bottom and there should be the word security somewhere down there, tap on that and enable fake system status, and reboot.
[AT&T Samsung Galaxy S 4 Android Development] norbarb:
Got it.... thanks
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
Your welcome :)
[AT&T Samsung Galaxy S 4 Android Development] xerythul:
Wow that actually works to spoof off the custom padlock screen at boot? I thought that was just for the about phone status page..
[AT&T Samsung Galaxy S 4 Android Development] mswal2846:
This didn't work for me. When I reboot I still see the Samsung unlock padlock screen. I installed on my ROM1 and not the Stock rom. Does that matter?

EDIT: So I installed on my Stock ROM and it worked. No more Samsung unlock padlock screen!
[AT&T Samsung Galaxy S 4 Android Development] princecharlsy:
noob question

im new to android. i currently have ss 3.64. how do i update to 3.65? thanks
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
download 3.65 from 1st page, open app and install package; when you reboot it should show 3.65 next time if all goes well.
[AT&T Samsung Galaxy S 4 Android Development] gadget069:
Made a small donation 0F599146GH781042P for your great work!. Hopefully 4.3 SS isn't to far away :)
[AT&T Samsung Galaxy S 4 Android Development] princecharlsy:
so no need to uninstall the older version?
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Nope.

[AT&T Samsung Galaxy S 4 Android Development] JohnnyMac999:
Deleting ROM Slots

I went through the process pretty successfully, made a ROM Slot-1 and installed the kernel fix and a compatible TW ROM (Hyperdrive). I made my ROM Slot 2G. As I started receiving my apps back from Google, I started getting a message that I was running out of storage. Maybe I made my ROM Slot too small? So I'm thinking of deleting RS1 and instead, reload everything to the default RS. If I delete RS1, will I still be able to boot to recovery? Will SafeStrap still be there? This makes me a little nervous...thanks.
[AT&T Samsung Galaxy S 4 Android Development] etu_aty:
Yes you can safely delete that rom slot 1 and safestrap will be unnafected, that is its function, create and delete slots safely. As far as the storage space goes i'm assuming you didn't wipe the stock rom slot before making the rom slot 1 right? meaning all the apps you are reinstalling are also intalled in the stock rom slot, that's where all your space is at. You can do a factory wipe in the stock rom slot with no harm, it just deletes all the apps and data leaving the system untouched and giving you some extra space for the rom slots.
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
In safestrap, I have personally found the only way i could possibly kill safestrap is flashing the stock rom in safestrap. Not even wiping the /system and installing a rom will remove safestrap. That's how I installed Google Play Edition on my phone, but because of issues, I will have to return back to stock... Probably real stock not even modded. I realize there is a lot of bloatware on stock. but thats usually installed on /system, and with safestrap, we cant change the partition size of /system on stock, so it doesn't really help us anyways. While I really did like GPE edition, the MF3 modules was not complete enough to fix USB mounting and hangouts video for me. Even today a twitter update crashed its official app. I had to clear that apps data to get it to work. I need stability, so I'm returning to stock (with SS installed). I'll stay there until I can install CM, then i'll stay there indefinitely. (on stock slot, regardless of /system size)
[AT&T Samsung Galaxy S 4 Android Development] JohnnyMac999:
OK, so I rebooted to SafeStrap, went into recovery and did a wipe on the stock ROM slot. I didn't just do a factory reset, but did an advanced wipe instead, and selected everything but MicroSD Card. Then I rebooted and now my phone won't go past the Samsung Custom screen with the unlocked lock icon. Is there any quick way to get back to SafeStrap, or do I have to recover with Odin, etc.?
[AT&T Samsung Galaxy S 4 Android Development] etu_aty:
Well.. you were supposed to flash something to boot into after you wiped everything, and apparently since you can't access safestrap I would say yes, you have to go to Odin and reflash stock MF3 image, re-root and reinstall SS, luckily we have an odin flashable of it now. Don't try any other stock image since you were on MF3 already and you run the risk of bricking your device.
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
When you wipe the stock slot, SafeStrap goes along with it... you need to flash whatever replacement your planning to use into the stock slot before rebooting. If you reboot your phone after wiping stock without installing anything your find yourself in Recovery / Download mode. Use the MF3 Odin files, and try again... after you install your 4.2.2 TW-Rom to the stock slot remember to flash the modules, and reinstall things like SuperSU (if your ROM doesn't have it), and SafeStrap itself as soon as you boot into the new system. At least this was the case when I tested flashing to the stock slot.
[AT&T Samsung Galaxy S 4 Android Development] jball:
And thats what would happen if we knew sooner that we could've flashed to stock this hole time.only back when Safestrap was fresh to our phone most people that don't follow instructions would be screwed.we all must READ/RESEARCH to the fullest before moving forward
[AT&T Samsung Galaxy S 4 Android Development] desertmod1:
I don't know why you changed it but now even if I specify more than the default amount of storage I still get an error that there's space left for apps. This never happened on 3.11 and I always chose just 2GB.
[AT&T Samsung Galaxy S 4 Android Development] ksj0823:
[MENTION=4243514]Hashcode[/MENTION] I saw a TWRP file in ex sd card after I install the safestrap. If I remove the sd card from the phone, is Safestrap still work without the sd card?
[AT&T Samsung Galaxy S 4 Android Development] HORiZUN:
Do what I did:

Load SafeStrap

Delete rom slots

Wipe stock slot. Install Google play edition to stock slot. Install mf3 modules. Reboot. Enjoy all your gigs back on your s4
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
Huh, you didn't have any issues with that?

Only my restore of gpe seems to have radio access. A basic version of the ota works, but a clean install refuses to.

A clean install of gpe that is, other roms clean install fine.

When you wiped, did you do a straight format?
[AT&T Samsung Galaxy S 4 Android Development] Hashcode:
Yep, SS will work without an ext. sd card.
[AT&T Samsung Galaxy S 4 Android Development] warrenstimpy:
I have the same issue when I clean install and I must be doing it wrong because I get the same problem when I restore too.
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
When I flashed, I couldn't do a straight update, I had to install clean or I would bootloop. By clean I mean wipe /system and everything but extsdcard. Maybe it depends on which gpe you flash.

Btw my hangouts crash was at fault of viper4audio :( I liked that too...
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
Looking at my file structure I am not certain running the format actually wipes it.. As I still have the rootpack in a download folder in my still double stacked /0/0 folders
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
Maybe, but whatever wiping it did, it allowed my installation of gpe to work. I have also noticed safestrap also survives the /system wipe. For I rebooted and safestrap still showed up.
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
Well turns out its safe to nuke that stacked folder. I think its were my rom slot was and I'd managed to confuse safe strap.
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
Got a hold of another S4 to play around with... I tried installing GPE via the stock-slot again and am still running into several issues. If anyone could explain the cause, or offer any insight into I'd greatly appreciate it. I wiped every partition, that being data,system, and both caches. So as for the issues...

No connection to AT&T's network. (LTE, 4G,etc) No signal at all, 0 bars.

No Mobile Data due to above

Under About phone the Baseband shows as Unknown, and under Status the phone reacts as if it has no SIM card. No IMEI #, Service, Network Type,etc

Camera App has an error connecting to the camera itself.

Mind you this a AT&T I337 on MF3 with SafeStrap.

Edit - This seems to be affecting anything I flash into the stock-slot... Odin'ing back to stock to try again.
[AT&T Samsung Galaxy S 4 Android Development] Galaxy*$4:
have you tried the mf3 modules? had to ask

maybe just try regular wipe instead of advanced?
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
Yes, and yes.

As long as a ROM is installed in slot other then the stock one everything works. I get signal, the camera app works,etc... but the moment I add it to the stock slot I get the unknown baseband and no IMEI #. It's rather annoying, considering I'd love to have that additional space back.

I went so far as to reflash the MF3 modem in case something got messed up, but to no avail.
[AT&T Samsung Galaxy S 4 Android Development] Galaxy*$4:
oh, dang i am out of ideas, the only prob i had with wicked 7 was random restart and no sound when playing anything over then google music app.

(re flashed rom work for me)

is it only on that gpe rom? if i didnt feel like loosing everything again i would try it to see if i get the same results
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
Nah, it same problem with Graviton which is my current day-to-day ROM. On Graviton in the stock-slot everything works (ie. camera) but I still get the unknown baseband and no connection to AT&T data or cellular network.
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
I have a very short list of ROMs that work in the stock slot.

I deleted some file structure stuff that might have been the cause.

If things aren't crazy at work I'm going to try gpe again.
[AT&T Samsung Galaxy S 4 Android Development] Silenus21:
Wait isn't it dangerous to install in the stock slot?

Main reason why we use safestrap.

I don't think I can risk it.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Not an issue now that the MF3 tar files are available. If flash to stock slot can use all your phone's internal storage not just slot size.

sent from my AT&T Samsung Galaxy S4 i337 MF3 with SS and GPE 4.2
[AT&T Samsung Galaxy S 4 Android Development] remf4i:
I got a new s4 that already has 4.3 installed, will this work with 4.3 ?
[AT&T Samsung Galaxy S 4 Android Development] Silenus21:
Oh didn't know that.

So I'm on shostock 4.2.2 now on new rom slot.

Can I make a titanium backup of my setup.

Delete the new rom slot

Download and install shostock on the stock slot.

Restore with titanium backup.

Any step I'm missing.

I wont change kernel, will use the one on shostock 4.2.2

Let me know, I want my space back.
[AT&T Samsung Galaxy S 4 Android Development] cyrusalmighty:
I dont think it works after MF3(4.2.2)... but does anyone know if it is being worked on and if there is any progress made on a 4.3safestrap yet?
[AT&T Samsung Galaxy S 4 Android Development] retyre:
Does this approach allow one to ("nandroid") backup the stock MF3? I doubt it does, but I'm looking for a way to backup the factory MF3 now that I have gotten rid of all the bloat. Can the Safestrap recovery access the MF3 in the stock slot?

Update: Looks like the answer to the above is "yes." I'm hoping restoring is as easy ...
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
Works fine. You might find a double 0 stack in your sdcard folder. You can delete the nested one through safestrap though part of linker rebuilds on boot to OS like you'd run fix permission.
[AT&T Samsung Galaxy S 4 Android Development] ksj0823:
I have the same question. Since we now have the MF3 files. Can we just flash the shostock rom on the stock rom slot? I am not feeling comfortable that 16GB version with 2 rom in the same time. not much space we can use after that.
[AT&T Samsung Galaxy S 4 Android Development] jball:
I use Hyperdrive on my "STOCK" slot.

I would imagine if it didn't act right on a Rom Slot than it probably won't work right on the Stock slot.so if its on the list it more than likely will work.
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
Yup, and to all of you who tried installing roms on stock slot, and get baseband errors, no cellular or wifi, that must be because the mf3 modules must have failed. Just keep trying flashing the mf3 modules until it works, and if it doesn't..well try redownloading the zip (make sure you can open it in Windows, it'll say if it's corrupt or not) and check the SHA1 sum to make sure you have right zip. If you've done all that, your phone must really not like you.

Never take the lazy train, and good luck :)

And yes, titanium backups (of user apps) works pretty perfectly for me. Just don't restore system apps... or updates of system apps.. let Google play handle that.
[AT&T Samsung Galaxy S 4 Android Development] Silenus21:
Ok I'm on stock slot now.

I deleted the other slot.

Now on ESfile explorer I see on dir emulated exdsdcard and a shorcut to sdcard0

Do I have to delete the emulated folder?

Inside the emulated is 0 and legacy

I don't want to have those dirs unless necesarry.

So which can I delete?
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
Say, does this mean that we're ok flashing new roms via safestrap to an MF3 unit?
[AT&T Samsung Galaxy S 4 Android Development] t4duzan:
As long as you flash a 4.2.2 Rom or older. Not sure if that's exactly what you were asking.
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
No, I mean that I have build JDQ39.I337UCUAMF3, and I thought you couldn't flash other roms to this yet. Does this mean I can flash a custom rom to it now?
[AT&T Samsung Galaxy S 4 Android Development] t4duzan:
You definitely can flash a custom rom (4.2.2 or older) to that baseband using Safestrap as your custom recovery. That's the baseband I'm on as well and I'm currently using a custom rom usign SS as my recovery.
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
Oh ok. I thought that the MF3 based phones you couldn't flash a new rom to. I didn't want to brick my phone. So you can flash via safestrap without bricking the phone?
[AT&T Samsung Galaxy S 4 Android Development] gogodj:
Is there any way to flash 4.3 Roms yet ?
[AT&T Samsung Galaxy S 4 Android Development] aycockonxion:
Not if you have the OTA 4.3 update with MK2. Give it a couple of weeks. I'm in the same boat.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Its ok to flash over the STOCK slot in safestrap now b/c the MF3 TAR files needed to ODIN back are now available.
[AT&T Samsung Galaxy S 4 Android Development] TheEgonSpengler:
Neither.

You can ONLY delete storage/emulated/0/0 if it got accidentally created.

If you have a rom slot set and installed this will break it!

But DON'T delete storage/emulated/0

You need those other "duplicate" folders/files you see in the emulated folder structure. (they only seem duplicate, its a file structure thing go with it)
[AT&T Samsung Galaxy S 4 Android Development] Hashcode:
I'm swapping the loaner Loki boot device that I've been devving on to a 4.3 selinux enforcing device. Should be here towards the end of next week.
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
Ok...I thought you could only have a rom in addition to the stock rom. Are there directions for this besides just the safestrap instructions? When did it become possible to flash over an MF3 rom? I thought that the thing was locked.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
You should read several posts back in this forum I think. Horizun posted all about his experience with this, and I followed what he did and it works. You could always flash over stock with safestrap, but it wasn't suggested b/c there was no recovery b/c none existed for MF3. Now that the TAR files have been made available a few weeks ago, people have been flashing without worry as you can go back to factory/stock with ODIN.

Good luck.
[AT&T Samsung Galaxy S 4 Android Development] aycockonxion:
Sweet man, that's awesome. Looking forward to it. Do you recommend to root with Vroot and the Chinese superuser thing and then go through the process in Terminal Emulator to replace it with Super SU?

(Reference: http://rageroms.com/index.php/topic,203.0.html, and it's also discussed on a thread around here somewhere but I can't remember where)
[AT&T Samsung Galaxy S 4 Android Development] gogodj:
I didn't do 4.3 update, on stock I am still on 4.2.2/MF3. but when I flashed GoldenEye 4.3 on another Rom Slot it didn't work......it just boots into to a black screen......What I was asking is...is there any way to flash 4.3 ROM on any slot when I have a rooted device with Safetrap 3.65.....
[AT&T Samsung Galaxy S 4 Android Development] dc5ftw:
Not yet. To my knowledge anyway. Especially if you had just flash 4.3 and that didn't work,I doubt any other 4.3 Rom will work with mf3 as of right now. Correct me if in wrong..
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
I did.

Just tried flashing Gravitron like he did, and I get everything working but I don't get mobile. I try to activate it and it tells me to install a SIM card even though I have one installed. I've flashed the MF3 files from the first page multiple times and while the MD5 fails it says that it's installing correctly. I've even downloaded it and tried installing it again. What am I doing wrong here? When I went to wipe I selected advanced and wiped everything but the Micro SDcard.
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
I've have the same issue with flashing into the stock slot. No connection to the AT&T network, unknown baseband, no IMEI #,etc it has been driving me absolutely bonkers trying to find the cause of it. While I can continue testing due to the MF3 Odin files it's time consuming to test then flash back to stock then rinse and repeat.

Sounds awesome! Can't wait to see what sort of magic you can work with 4.3
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
So basically I'm back to the stock rom until this mishegas gets sorted out?
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Had the same problem with Graviton on my slot slot. So just ended up flashing a different 4.2 ROM and it works flawlessly.
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
I tried the google rom and it's still not getting signal.
[AT&T Samsung Galaxy S 4 Android Development] NighthawkXL:
I might try Hyperdrive and see if it works without issue, but yeah both Graviton and GPE didn't work right for me either. Still wish we could find the root cause of it, considering it works for some people but not others. We need to determine if it's issue with SS itself or something to do with the phones. Hey [MENTION=4243514]Hashcode[/MENTION] any chance you know where this bug is coming from? No baseband, no IMEI #,etc. after flashing to wiped stock slot. I've already ruled out the EFS as the culprit.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Hmm.. I don't know why. I flashed the GPE 4.2 ROM over my stock slot and had no problems with all features. I changed b/c I missed multiwindow option but WiFi, data, etc all worked. You flashed the MF3 kernel mod after as well, like when using safestrap previously, right?
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
You mean the mf3 file off the first page of this thread with safestrap? Yes. I downloaded it twice just for good measure
[AT&T Samsung Galaxy S 4 Android Development] Lex_407:
I've been reading and I want to know if it's ok to flash 4.3 roms on the secondary slot? I have updated my SafeStrap and I was looking to see if I can install any 4.3 roms. I'm running on MF3 currently. Thanks in advance.
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
Yup that's the one.

---------- Post added at 07:21 PM ---------- Previous post was at 07:19 PM ----------

Keep reading. Can't flash any 4.3 roms with safestrap. Not supported. Think it's in the OP.
[AT&T Samsung Galaxy S 4 Android Development] kruuth:
Ok. So basically, you're going into safestrap, goign to wipe, and wiping everything but the external SD, flashing the new rom, then the MF3 fix?
[AT&T Samsung Galaxy S 4 Android Development] jt1998:
yup.

Unknown Baseband / No Service Bug Status

UPDATED - 4:43 PM EST - 12/4/2013

Well, I managed to get the Google Play Edition working in the stock slot without running into the Unknown Baseband / No Service issue that some users are having.

Going to play around with a few more ROM's to determine which ones are susceptible to the bug. The problem however is we need to track down where the issue is coming from... is it SafeStrap, something in the ROM's, or is it just the device itself at random?

I've already ruled out the EFS as the culprit, there is something else causing the issue. With that said also be sure to check the MD5 hashes of your ROM's and the MF3 modules before flashing them as it's been known to cause similar issues.

So to start with... here's a list of ROM's and there Unknown Baseband / No Service bug status. If you happen to be running a 4.2 TW-Rom in the STOCK slot that isn't listed or untested feel free to PM me with your results.

Google Play Edition (Non-Slim) - Working

Google Play Edition (Slim) - Not working, may work for others.

Graviton - Not working, may work for others.

Hyperdrive - Working (Thanks [MENTION=4425542]jball[/MENTION])

Intika Locky - Working (Thanks [MENTION=5563008]TheEgonSpengler[/MENTION])

Deadly Venom - Working (Thanks [MENTION=5333042]jt1998[/MENTION])

SHOstock - Working (Thanks [MENTION=4675826]davebegue[/MENTION])

Wicked - Working (Thanks [MENTION=5419031]Galaxy*[/MENTION])

Yes to Hyperdrive with ATT compatibility package,MF3 Module is doing great for three weeks strong
[AT&T Samsung Galaxy S 4 Android Development] tommydrum:
Somehow the Kernal modules isn't installing for you... I would try extracting the zip and replacing the files manually on phone to test. Maybe the installer script went rogue :(
