Hello guys, I'm trying to unlock my sprint S4 to use with metroPCS....I got the phone from a friend of mine because he switched to iphone. The phone is currently running the cm11 archerom rom with NAE baseband
What I've done so far was
- followed the international sim unlock guide and was able to downgrade my modem from NAE to MDC via odin running cm11.
- I couldn't get the phone to go into Diag mode to use the s4 unlocker program...I tried using scripts (Aosp script for diag mode) but the phone would not get recognized on my computer ( running windows 8) so the S4 unlock flasher couldn't detect the device.
- I tried to odin the phone back to stock samsung twz so that I could get into diag mode easier. I flashed stock MF9 rooted touchwiz rom via odin but it failed everytime. I was trying to flash the mdc baseband after so that I could use to unlocker program.
- The phone soft-bricked after that but I was able to fix it by flashing a custom recovery but my phone audio went out with DSPmanager crashing and music, audio not playing.
-I resolved that problem by flashing back the NAE modem, now everything is back to where I started from, I'm not sure where to go from now
What I might do next is, try to use cwm to flash back to stock samsung twz rom but I'm not sure which rom to flash in order for me to unlock my S4....
What do you guys think? Thanks for reading!
Odin full NAE. You cannot downgrade the bootloaders thus why you were not able to successfully Odin MF9 because you have a Knox boot loader.
I tried flashing the full NAE ROM via Odin....it almost went pass "system.IMG.ext4" in Odin and then it failed on write nand...
I flashed recorevry and now /data is not mounting. I flashed the achrom c11 ROM again but its not booting now, its stuck on the android screen (soft-bricked.)
What should I do next? Thanks for your help BTW

It sounds like you had the 4.3 update, because it sounds you like you are trying to install an older bootloader over the the locked MJA bootloader. So the update went through, now you cannot go back to MF9. The bootloader isn't corrupt, its locked and only the MJA bootloader can be flashed through Odin. You'll have to go to http://www.sammobile.com/firmwares/ and search for the 4.3 MJA file to flash to your fone, the cf-auto root, then flash a custom recovery...
Hello everyone I have a weird issue here and I am in need of some help. I was running a stock MK2 rooted rom, with the modem/firmware MK2 with the MF9 bootloader. When the first NAE (4.4) ROM popped up I decided to give it a try and installed it without getting the NAE modem first. The ROM wouldn't get past the splash screen and other users experienced this too, I figured I should get the NAE modem so I installed it and rebooted hoping it would get past the splash screen. I came to a conclusion that it probably isnt going to work right now so I did a nandroid restore back to my stock MK2 ROM. Upon booting it up I had no data, signal bars with a red X and in About Device section it says baseband unknown and in the status section everything is unknown or has no field. I thought my modem was broken so I tried a 4.4 kitkat ROM OctOS which worked perfectly and I got signal on that ROM. So this brings to me another hypothesis that my modem is fine as I could make calls and what not, no issues. However I tried reinstalling stock MK2 and for some reason I get no signal...
I am not sure whats going on here, I tried a MF9 Stock Tar and formatted the whole phone, tried installing MK2 and MF9 modem and I get no signal on the stock MK2 ROM. I am a little lost here and asking the XDA community for help, I really want to go back to my old setup. Please help me out here.
My situation is kinda similar to yours. I also had no service and got an Unknown baseband message in Settings when I went from stock rooted MK2 (with stock MK2 kernel and MF9 bootloader) to the new NAE ROM and NAE baseband.
I suspect that NAE requires a Knox bootloader for service to work.
Anyhow, to go back to a fully functional MK2 state, here's what I did:
1. Restored my MK2 Nandroid using Philz's recovery.
2. Booted directly into Download mode from Philz and flashed back the MK2 modem with Odin 3.07.
3. Rebooted phone and everything fully works again.

modem didn't stick maybe?
Had issues playing with the new modem and nae ROMs. Unknown baseband and no days. Even a ##72786# led to a blank screen with no option to reset. So I played around with different install techniques and got a ROM to fully function.
Unknownforces stock rooted nae. From android development forum.
1. Clean to install new ROM using Philz 6.0.8.9(what I used) said any can be used
2. Even of you have already flashed new modern do it again now
A. Power completely off
B. Go into download mode
C. Odin new NAE modem(auto reboot and freset unchecked)
D. After Pass reboot into recovery
3. Clean wipe for new install
4. Install unknown forces ROM
5. Reboot and enjoy data working and WiFi working
Hello,
I have an unsuccessful firmware update.
First flashed the last stock rom, cf-autoroot. After it I try to flash the CWM, and this is the end,
Now there is no boot loader, no recovery. I see the "Firmware update encountered an issue...".
The knox is 0x1, Writeprotect enabled.
The only thing is working on the phone is the download mode, but every attempt to flash in Odin fails. (aboot.mng..Fail)
I tried to flash another bootloaders, repartition with pit file, but not works...
Done it on other PC, usb ports...
Now I know what was the wrong with the installation, but I need a solution for this situation.
Please, help me...
You will have to flash through ODIN Kit Kat. You cant come back to 4.3 or 4.2.2 if ya flashed android 4.4.2 and u updated the bootloader. Select one android 4.4.2 firmware in SamMobile for you and update ur phone :highfive:
Thanks for the reply...
The last firmware I flashed was 4.3, and I cannot reflash it.
But I will try a Kit Kat, which one is good for me? I have an unlocked phone and my country (Hungary) does not have it yet.
Can I flash it with knox 0x1?
Thanks for the advice, the phone is working now....
The whole story:
- the phone had 4.3 custom ROM before.
- I flashed the new version with 4.4.2: new recovery, modem and ROM.
- From here I had no sound. I tried to flash everything 3 times, an no sound.
- I searched for this, threre were many good advice, I tried some and the phone not booted.
- Downloaded the latest Samsung firmware (I9505XXUEMKF_I9505OXXEMK3_I9505XXUEMKF), flashed and no sound.
- extracted the modem.bin, flashed, and flashad the ROM again, sound is good, I was very happy.
- CF-autoroot, I saw it was working
- Flashed the CWM recovery, Fail in Odin and...no boot, no recovery, only download mode.
- Flashing the original downloaded firmware (I9505XXUEMKF_I9505OXXEMK3_I9505XXUEMKF) is failed. I don't understand, it is not downgrade...
- Flashing a new Kit Kat (I9505XXUFNB9_I9505EURFNB1_I9505XXUFNB9) was successful.
How can I use a custom ROM again?
I am afraid, if I make an error, cannot flash again the same, I have to wait a new one?
Hi Guys,
After rooting my phone, trying different Custom Roms and reverting to stock a couple of times, I now have soft bricked my S4, or at least I hope it's only a soft brick.
I upgraded from JB 4.3 to Kitkat 4.4 and TWRP recovery a couple of months back. I live in Australia and as yet we don't have access to Stock Kitkat 4.4, so I flashed the United Kingdom XXUGNG8 (BTU) firmware. The phone began to lag and a couple of the functions refused to work, so without thinking I attempted to flash back to JB 4.3.........I know, I know you can't do that, but tat the time I was frustrated with it's performance and I didn't think before I acted.
Anyway, first I was unable to enter Recovery mode......nothing worked, the phone would just boot to the error screen. I was able using Odin 3.07, T erase all, flash a .pit file and obtain a "pass".
Get pit for mapping
Firmware update start
RQT close
Res ok
Removed
Remain Port.......0
All threads completed (Success 1/Fail 0)
Then when I attempt to flash a stock rom, it fails every time at "System Write".
I now have discovered that a "Phil's Touch recovery .tar" can be flashed, but nothing else.
When I boot the phone up, it hangs at the Samsung Galaxy S4 iGT9505 screen.
What have I done wrong guys, have I completely corrupted the phone, or is it recoverable? Please Help.
Regards.
You can't revert back to 4.3.
So flash a custom rom or a stock 4.4.2 rom and you will be fine.

Yes thanks for your reply. I re flashed a pit file and stock rom together and it appears to be working fine now.
Was running alliancerom on 4.4.2 and found the unlocking bootloader option. Unlock worked and tried the jasminerom after installing ttwrp-3.0.2-0-hltevzw-4.4.img. Then discovered cm13 which worked great but discovered a kernel opps so installed new modem and bootloader based on of1. The bootloader bricked. Odin won't let me install the retail stock roms. It gives an error in korean. I was able to install of1 recovery but cannot get the system.img.ext4 thru odin without the korean error popping up.
At this point I don't see how I can return to stock. Is there a way out or do I have a dead device? Any help appreciated.
Thanks.
