Can't get multi boot to work on my S4 - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi all
I have been trying to install a second rom on my phone so I can multi boot into another rom besides my stock rom. I have safestrap 3.72 installed. Rooted. With the following setting as in the attachment.
I tried installing golden eye and cm11 rom into my first slot from safestrap activated it. But when I boot my phone it always boots back to my stock rom with a broken modem? everything works except no reception with a blocked signal icon.
So I reboot my phone back into the stock slot and reception is back.
I followed the procedure from the custom rom install. Wipe everything twice after choosing the 1st slot. Install the rom. Then the SU. Then the modem NC1 module. Yes I am on NE1 but I can't find a NE1 module.
TIA

I also tried the pure nexus rom but I think that one only works if I install in the stock slot only? My phone Service provider is rogers

Anyone else had this problem?

Did you install the right golden eye rom for your version? Also did you flash the correct moden for your version? cyanogenmod is not supported on the safestrap as long as the bootloader is locked. You can only flash TW based roms right now. Try flashing stock firmware with Odin and fillow the instructions very carefully. You can find roms and instruction for your version in the general forum.

Someone said SS 3.72 doesn't support multi boot. Is that true?

You need 3.75 to create rom slots, rom slots aren't supported on3.72 .

You're on an I337m, not an AT&T I337. Safestrap isn't made for your device and you're lucky if it functions to any extent without messing up your device. Since your bootloader is unlocked, however, I believe you should be able to use MultiROM.

thanks guys, I didn't know that was the difference between the Rogers I 337 M and the AT&T I 337. I will try to upgrade my safestrap 3.75 if that doesn't work I will try the multi boots suggested by death sin

[Q] Safestrap compatible roms with NC4?

Is anyone aware of safestrap roms that work with NC4? I'm having trouble finding a list or anything...

It seems like BajaROM doesn't work (failed for me and apparently others). Was planning on trying JasmineROM next.
None of the current roms worked for me. (Stock TW KK 4.4.2 NC4 OTA) Rooted /w busybox, safestrap, and super su binary installed.

Hope it helps
No I was on NC 2. Downloaded and flashed jasmin rom and rebooted into Odin (download mode) and loaded nc4 firmware thru Odin 3.09
I was on NC4, no luck finding anything that is working (including Jasmine). Install seems to go OK, but when I reboot the screen stays off.

How did you install super su?

Never mind after the 9th attempt it finally stuck

You can download & install SuperSU from playstore...
Open SuperSU it will prompt you that the binary needs to be installed, click ok! It will then say failed and give the option to install it via cmw or twrp click ok! The system will now reboot to the stock recovery, exit out and reboot to safestrap. Once in safestrap choose install and go to "/cache/recovery" and select "update.zip" swipe to flash then reboot to system. Open SuperSU and now it should be working.
Lmk if this works for you...

ALL, Please DON NOT try and flash any ROM if you are coming from the Verizon OTA NC4 4.4.2 build (rooted via Towelroot)...until the ROM Developer states in the OP that it is okay to do so.
EDIT: Please refer to this thread if you are on the VZW OTA 4.4.2 or NC4 kernel: http://forum.xda-developers.com/showthread.php?t=2787627

That fixed it, thanks
@JBHawaii will that method work for stock build NC4? Currently SafeStrap isn't letting NC4 flash ROM at the moment.

Yes, it will work for stock NC4. However, chainfire just released an update for Super SU via the playstore... try that first! If the binary still fails to install then try my method.

Has any one ran safestrap and check the size of the rom slot? When I do it says 0 mb available. If I am not wrong which I could be that means there is zero space to flash the rom to.
Sent from my SM-N900V using XDA Premium 4 mobile app
Right now SafeStrap won't let us use slot for ROM, so we can't flash anything to it

Flash NC2 Kernel in Odin
Just flash the NC2 kernel in Odin and install a rom. Just tried it out and it works!

What kind of custom rom you were using?
Now im using a stock, however, I did not installed by Odin. I found one flasheable by custom recovery.
PS: My devide model is n900w8.
And I found a few versions of roms stock, however, all that have a same bug, force closes and reboots. I tried install by Odin, and also flasheable, and got a same problems. Roms for n900w8 is all a trash.
I found a ROM stock flasheable for n9005, and its working fine, but WiFi and NFC is not working.

3.72 definitely doesn't support rom slots. 3.75 does but not everything works when using rom slots.
Thanks for the info. I am on stock 4.4.2 with NE1 modem and 3.4.0 kernel. Is there a way to find out which rom will work with 3.75 SS?

[Q] About MF3 and updating

I'm on 4.2.2 mf3 with root and safestrap installed. Just wondering if there was anyway I could update my phone to 4.3+ maybe by flashing a custom ROM? I don't have access to a computer so I can't flash Odin files to update. Am I forever stuck with 4.2 until I can get access to a computer?

You can always go with the stock touch wiz Golden Eye custom Rom to get you to 4.4.x. It works with safe strap.
Since you are rooted, you can probably use Mobile ODIN to flash ODIN files without a PC, if it will work with safestrap, I am not sure or not.
You might want to check the General Forum too, there might be an update .zip file you can use with safe strap to get you to 4.4.x
Wouldn't I have to update my MF3 baseband? And would I have to flash it over my stock ROM slot? AFAIK mobile Odin doesn't work with the att variant of the s4. So I can flash any ROM compatible with safestrap regardless of whether its 4.2 or 4.4?
