What ROM were you on, were you on NB1 at any point, did you flash the NB1 or MLD bootloaders? You should always be very descriptive in order to receive help quickly.

thanks for replying!!!

[Q] Can't install ROMS with safestrap with Samsung galaxy s4 at&t MF3

Hello,
I have a samsung galaxy s4 at&t on MF3. I rooted using the xda guide for MF3, and installed Safestrap 3.71 and TWRP 2.6.3.1.
Then I installed on ROM slot 1 several of the ROMs from this thread http://forum.xda-developers.com/showthread.php?t=2428254 including
Google Play Edition 4.2.2, Deadly Venom, SHOStock, Darth Stalker x1 but none seem to be working.
After installation is complete, I reboot on ROM slot 1, I see the Safestrap splash screen, then the screen turns black, the phone vibrates, and reboots again.Then it depends. I will see one of the following:
1. After the samsung logo with RECOVERY BOOTING in tiny blue letters on top, I see a recovery screen with a dead android that says "android system recovery <3e>" which gives me a few options (like reboot system, apply update from ADB etc). I have only chosen reboot, which is a regular reboot leading to the regular safestrap splash screen.
2. Samsung logo and regular boot, which leads to the safestrap splash screen.
What am I doing wrong? Are the ROMs I have tried not compatible with my phone?
I would appreciate any help.
thank you very much for the hard work!

Why flash TWRP? You already have safestrap, no need to flash a custom recovery that doesnt work on MF3.
Also have you flashed the MF3 module after flashing a rom?

Safestrap 3.71 is for mk2 builds. You are mf3 so you need 3.65. Safestrap is a modified TWRP flashing TWRP over it is needless & not going to help your phone. PLEASE READ! All this information is here on XDA for you. Plus horror stories of the uninformed who did as you & flashed 1st & asked questions later. Hopefully you made a backup before all this, if not, then there is a guide posted on here how to Odin back to stock mf3. Good luck.

Thank you much for the prompt reply.
My phone boots fine the Stock ROM and works fine on the Stock ROM. Can I just install the right Safestrap version (3.65) after I boot the Stock ROM, and take things from there? or do I need to Odin to stock necessarily?
Thank you very much

Thanks for prompt response. To clarify, I only installed Safestrap 3.71. I did not flash TWRP myself. I only mentioned the TWRP version that was inlcuded with Safestrap in case this was important for your answer.
I have tried flashing MF3 module after each rom with no luck.
Based on the response of another fellow, I think what I did wrong was installing the wrong safestrap version.

Whew, so glad your phone is fine. Yes, install Safestrap 3.65 then you can flash the mf3 custom rom of your choice in Safestrap recovery. Remember, Safestrap will always show as disabled on stock rom & active on a custom rom slot. Be sure to read & follow the rom developers install instructions. Safestrap has worked flawlessly for me. Don't forget to thank Hascode for his brilliant work.

Goldeney can`t get past booting logo

Hi everyone,
I have an i337 that was updated to NB1. I used the NB1 to MK2 downgrade method to root and install safestrap on my phone. I`ve been able to successfully only install deadly venom`s rom on the stock rom slot so far.
I tried installing version 25 of Goldeneye 4.4.2 along with the Super SU file, but it never gets past the boot animation. It hangs on the glowing Samsung logo and glowing blue LED. I`ve even done a full Odin back to the MK2 rom then wiped and reinstalled it. It keeps hanging on the splash screen. I just reinstalled Deadly Venom earlier to get my phone running again and that worked without a hitch.
I read that V25 doesn`t need me to edit the updater script like V24, so I skipped that. I also made sure to install the NB1 kernels with Odin and the ATT NB1 Modules zip in SS before performing a full system boot. Was there something else that needed to be done before booting up?
Anyone`s help would be appreciated.

[Q] Running 4.3 ROMs with Safestrap 3.72?

Hi all,
I just bought a new i337 and it came with the NB1 bootloader, NB1 stock, and I followed all the steps to downgrade, etc and have SafeStrap 4.72 running it with a rooted NB1 stock firmware. However, there are some things I like about 4.3, and I would like to run SHOSTOCK (JellyBean version), but I know that I flashed a NB1 Kernel through ODIN as part of running the rooted NB1 stock. Do I have to start over and downgrade it back to MK2? Or is it as simple as just installing the SHOSTOCK for Safestrap in SafeStrap 4.72 even though in the SHOSTOCK thread they don't mention anything about 4.72, just 4.71. I guess I'm just concerned about the kernels not matching with the locked bootloader and all.
Thanks in advance for any help!

Safestrap v3.72 will mount on both 4.4 and 4.3 kernels. No need to switch back to v3.71.

Thanks for the quick response and answer.
Just a quick clarification, I cannot use Safestrap 3.71 anyway due to my phone having the NB1 bootloader, right? I thought v 3.71 was only for those on MK2 or below.
Thanks again for all your awesome work on finding workarounds for rooting NB1 phones and above!

No the SS version has more to do with your kernel not the BL. You can theoretically flash a 4.3 ROM using SS 3.71 on your 4.4 BL. There are additional requirements like modules, etc that I won't get into.
Well, I was trying to installing SHOStock 3.0- safestrap version today, and I kept getting the "cannot mount /system" in SafeStrap while installing. After rebooting a couple of times, I think I stupidly decided to do an advanced wipe of /system (among others). Do I have to go all the way back to stock NB1 (Original NB1), and then start the whole process to MK2->Root -> Safestrap all over again?
Thanks for any help!

Use the downgrade to MK2 file from this thread then root and install safestrap: http://forum.xda-developers.com/showthread.php?t=2692825

Thanks for all the quick replies. Just to recap, ODIN back to Stock NB1 (no need to uninstall the remnants of SafeStrap I have now?), Downgrade to MK2, Root, Safestrap.
Also, I'm not sure what I did wrong when I went from rooted Stock NB1 to try to flash SHOStock 3.0 (which was 4.3). I honestly wasn't paying attention to the messages, so maybe I had a unable to mount /system error then, but then I went to reboot it, just was blank. That's when I decided to be stupid and go to recovery to advanced wipe including /system. I guess now if I want to run SHOStock 3.0, or whatever ROM, I can just install it once I have Safestrap rather than installing the Rooted ROM and kernel, right?
Thanks again!

No need to odin back to stock NB1, the downgrade file will get you back to a semi-functioning(no-wifi) MK2 at which point you can root and install safestrap. From there go to the SHoStock thread for instructions on how to properly install that particular ROM.

Thanks again for the quick reply.
Just to clarify, I guess I'm really confused about what kernel I would have if I flash the downgrade file? Would it overwrite the NB1 kernel I flashed after I flashed the rooted stock NB1 in Safestrap? I noticed that in going to rooted stock NB1 (or NC1), you have to ODIN flash the kernel.
Thanks again.

Yes the downgrade will revert you back to mk2 kernel in order for you to be able to root.

[Q] may have bricked my nc1

Ok so I had a nc1.. used towel root,rf, and safe strap.made a backup and tried flashing gravitron... now I'm in a nonstop bootloop or I'm at the warning custom o's found.... can any one tell me where to start to fix? Currently downloading Odin to try and flash a stock image if it has?

Do you still get the Safestrap splash screen on boot? If so you can just restore or reflash. Otherwise, you'll need to use the NB1 Odin and take the NC1 OTA.
Before you flash again, make sure you wipe in Safestrap (all but external SD) and check your ROM. Make sure it doesn't need an updater-script in the All Things MK2 & NB1 thread and for gravitron specifically download the Safestrap version of it.

[Q] Why can't I get a custom rom to boot?

Hi all,
Working with a AT&T NC1 safestrap phone. Having problems getting any custom rom to boot. Phone usually shows white on black Samsung logo for a few second then restarts, sometimes into stock recovery.
Detailed below is my method, and methods tried with same result. Perhaps someone can see the error of my ways.
I have been trying to start fresh.... so:
1) Odin I337UCUFNB1_TWRootable_Full_Odin.tar.md5
2) Do not boot, Download mode and flash 2400258.zip
3) Install tr, and SS 3.72
4) Reboot into recovery, install Hyperdrive 18.1 or Gravitron S4 3.2 for SS, then flash SuperUser then NC1 module.
No matter what, I cannot get a rom to boot. Just hangs at Samsung logo
Other methods tried:
1) Using I337_NB1toNC1_KeepRoot_OTA.zip and/or I337_NB1toNC1_KeepRoot_OTAwBL.zip to flash to NC1 before custom rom (after Odin NB1) (instead of 2400258.zip)
2) Using NB1 Odin Files from Magic Tool BL,AP,CP before flash of custom rom, tried also after flashing custom rom
3) flashing NB1 stock kernel
4) flashing NC1 stock kernel
Tried maybe 30 or 40 times, cannot get a custom Rom to boot. To be clear, stock boots just fine whenever i Odin back and upgrade to NC1.
Anyone out there insightful enough to lend a hand? More detailed instructions than on INDEX ALL THINGS POST? See my mistake? Losing my mind just a little bit, flashing the days away...
Any help greatly appreciated!
Are you trying to flash a custom ROM in the STOCK slot? Or a second slot?
I do NOT have safestrap but I know I have read you HAVE TO flash Roms in the STOCK Slot for it to work.

Is your ROM SafeStrap Compatible?
Yes indeed. Tried a variety of them off the safe strap compatible page. I feel there is something I am missing but not sure what. I have been wiping data, davliche, cache, and system each time. Is this correct?
