You can just reboot the rom... then recovery safestrap splash screen will come up.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] rebel1699:
There is really no need to re-install safestrap on roms in slots. There is also no need to reinstall it in the stock rom. It is still there.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mrro82:
OK. Thanks. I'm wondering if that's why I keep losing sound after I reboot.

Are you also flashing the mf3-modules.zip after installing the rom?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] sykoj82:
Just flashed echo Rom from the i9505 forums...everything is working great. :) love safestrap!
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] coffeehandle:
i wasnt 100% sure myself. But i was confident to correct an issue if it occurred.

But yeah so far no problems,

Echo good for you?

What kernel version does your ROM say in about phone?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] sykoj82:
The only thing i haven't tested is calling, whether people can hear me or not. On the galaxy s2 i777, if u flash a international Rom, you must flash mic swap custom kernel ..on a i777 Rom, you use a non mic swap version of the custom kernel otherwise people could barely hear u. I'm assuming there is no need for that on the s4.

Edit: i just noticed i have to input the apn settings for LTE otherwise it uses the hspa+ apn setting and change network mode to gsm/lte. Also phone works, people can hear me...so looks like the mf3 kernel is compatible with any 4.2.2 touchwiz Rom on safestrap, at least what I've gathered after testing 6-7 different roms so far.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mrro82:
I did. That must have been my issue. I rebooted and still have sound. :)
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] coffeehandle:

So I have gravitron 1.4 in slot 1. I installed the gpe rom in slot 2, didnt like it and ditched it. Now its telling me my free system space is only 2096mb. Not enough to activate the second rom slot again. Where did I go wrong here and how can I clear up space that I know is there?

Edit: figured it out. Just in case anyone else runs into the same problem it appears that the default download folder is changed to the internal storage of the phone when using a rom through safestrap. Instead of the files going to the download folder of the extsdcard. Easy fix to move them over to storage/extsdcard. Space created, problem solved. Sorry if this is posted elsewhere but if it is I could not find it. Cheers!
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] JohnMcW:
Let me see if I understand what you did:

When you flashed a rom and then re-installed the safestrap.apk,

when you rebooted, you lost sound.

But, you Re-Flashed a rom, did not install the safestrap.apk,

and the sound works when rebooting?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] mrro82:
I would reinstall the ss recovery through the app because it didn't show as being installed. Multiple reboots and I still have sound so when I reinstalled that recovery it must have done something.

For the people using gravitron. Did you do anything special to get it working? Mine boots up fine but I have no working keyboard when I try and sign in only the talk to text mic shows up and when I hit the keyboard next to it nothing happens. Can't get into settings either to see if maybe the keyboard isn't ticked.

Which s4 do u have? Sprint? Att vzw locked bootloader users use safestrap and all we had to is flash rom then kernel module patch...i had no keyboard issues...only thing I think of is to search for google keyboard in the market and download that...or flash Samsung keyboard from somewhere.

Ouch.. I had no issues...go to stock rom...find a samsung keyboard somewhere from some forum and download it...go back to your slot whatever (gravitron) and flash that keyboard zip
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] jeboo:
I think it'd be great if a separate thread were started for ROMs (in)compatible with SS for ATT (MF3). This would save people a lot of time testing ROMs!
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] sykoj82:
I agree..I was thinking about that yesterday since I've flashed a bunch so far from i9505 forums at&t and next is tmobile wicked rom sometime when I have a second. I may start a new thread myself but hoping someone else would beat me too it lol..

Edit: also how if someone does flash from i9505, or another carrier' rom.. u may have to input at&t LTE apn settings plus change the network...also a few things may not work too like samsung air view etc..also you could lost root on that particular rom...

WaitWait... your running sho with ktoonz using SS? if thats the case im gonna flash that right now im just running sho with the sho kernal
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] rebel1699:
Your both running nothing more than those roms with the stock kernel. Safestrap blocks the kernel from being installed to rom slots. The boot.img in those zips are not even used. To accomplish that, you would need kexec for the stock kernel to handoff to the modded kernel, and safestrap does not contain kexec. If you check your "about phone" section of settings, you will see it is the stock kernel only. That is how safestrap was set up. Hashcode was very clear on this. It is also why you have to flash the mf3-modules.zip. Because they are needed to make the rom work correctly with the stock kernel from the stock rom.

Guess I was wrong lol. I might be thinking MDL based kernels with i9505 roms then. Good to know though that you can run with Omega
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] thedr9669:
To help with the working ROM's here is what I am running:

AT&T S4, MDL firmware, running Alpha 7.5 with the Bioshock 2.0 kernel in the stock slot. I have Alpha 9.1 working in slot 1. Everything I have tested so far works. WiFi was not working at first, but I went back and re-flashed the Bioshock kernel and Loki'ed slot 1 and it now works.

Question, can I backup my ROM from a slot and use it to update my stock slot? I would assume that when I flash my stock slot that I would do it thru my standard recovery, CWM, which is still accessible using the volume up.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] coffeehandle:
Why are you using ss if your MDL
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] graydiggy:
How many times do I have to explain this? I am a tester. As a tester, things can go wrong. I am using SS for the multiple ROM slots and for safety. If I flash a ROM and it gets borked, my daily is untouched, and I can still have a usable phone. I can also have up to 5 custom ROMs to play with.

So with everyone saying I don't need SS. You are very incorrect. I need it for the stuff I do with my phone.

Downloads section has a new Safestrap version:

Safestrap-JFLTEATT-3.6x-B09.apk

CHANGELOG:

No more wipe error on /cache

Reworded the /boot not found message as INFO

Boot partition should be protected in stock now. (In past versions, a boot.img file in a .zip being flashed to stock would overwrite the actual boot partition and force the use of ODIN to restore the stock boot partition).

3rd and 4th CPUs are reattached correctly after 2nd-init (this was reflected in lower benchmarks)

Installation scripts were debugged a bit. But still seeing some users not getting a clean uninstall. :/ I'll work on this more.

TWRP update to 2.6.3.0 (See change log here: http://www.teamw.in/project/twrp2). And if you like TWRP don't forget to let them know.

From a local build stand point, this update was HUGE for me. I redesigned how the recovery files are built in order to support / maintain more devices in a better manner. This portion was not reflected in the change log but hopefully helps keep the builds consistent across several devices in the same family (VZW, ATT, ATT-ACTIVE).

INSTRUCTIONS FOR UPGRADING

Boot to your stock ROM

Install the new APK via file manager

Make sure to agree to the warning about replacing the existing APK

Once you're in the new APK (you'll note 3.60 in the lower left corner), use the "Install Recovery" button.

That's it. Now you can reboot into recovery and go right back into your ROM slot.

[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Hashcode:
This is by no means set in stone, but feature / changes that I'm looking at for the next update include:

- Customizable partition sizes (system, data and cache)

- A method for automatically copying the kernel modules from the stock slot after any flash or restore to rom slots.

- Adding more info to the ROM-slot screen (mostly taken from the current build.prop)

- ROM-slot management to include moving to / from SD card for storage

- Splashscreen (during the boot) options for how long to be shown or hidden all together, custom images for when a rom-slot is active, etc.

- Add virtual boot partition to ROM-slots where .zip files with boot.img files could write to. Then after flash, the ramdisk would be extracted for use with 2ndinit. More ROM compatibility with this feature.

And, of course work on kexec to get custom kernel support.
