[Q] I'm trying to sim unlock my S4...please read!

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

trying to root Note 4 5.1.1 on 910W8

Hey guys i followed this youtube guide for rooting 5.1.1 using TWRP Method https://www.youtube.com/watch?v=qpsGX_Xoxcg
i downloaded all the files but the firmware (not listen i have n910W8 = telus)
I have odin, supersu, TWRP (which n910w8 is listed) and samsung drivers.
I moved superSU and the TWRP file to root directory of note 4 5.1.1. rebooted into download mode, saw the blue indicator on odin and loaded the file. Rebooted holding volume up this time and tried to load the kernal but it doesnt exist.
I think im confused the TWRP file is NOT the kernal? Where can I get a kernal for n910W8 (telus)
thanks in advance!!

So I found this
http://www.sammobile.com/firmwares/download/56498/N910W8VLU1COI4_N910W8OYA1COI4_TLS/
which is telus 5.1.1 Rom. ill move this to my root directory and load the 910W8 TWRP file in odin and flash? Ill give it a try now wish me luck lol

ok i followed a guide online and now my phone just keeps restarting. I think im in big trouble. Im able to load openrecovery-twrp-2.8.1.0-trltecan.img into odin and boot to TWRP but now i cant load kernels? looked so easy to do now im down a phone? any help is much appreciated thanks!!!

You need to odin (bell, rogers, telus) 5.1.1 then odin TWRP then twrp a custom kernel. Our 5.1.1 needs a custom kernel in order to work rooted. Or.....you can load a custom 5.1.1 rooted rom that is W8 compatible or any Tmobile rom such as Tekxodus which i am running.

ok so i loaded openrecovery-twrp-2.8.1.0-trltecan.img in AP (for my device) copied the custom rom
" cm-12.1-20150423-NIGHTLY-trltetmo" which was suppose to work with my 910w8 (910T) used recovery to flash it and also supersu it flashed OK... I restart and i see a little blue guy and its stuck optimizing apps. Suck in restart loop.
what did i do wrong? try a different kernel ?
thanks in advance
EDIT 1
im trying the " Tekxodus" rom. this file is way larger whats going on with that. Is it the same procedure to flash it?
EDIT 2
Flashed to tekxodus rom optimizing apps... now its stuck System UI has stopped. and I cant do nothing. Any suggestions? ?? ?
EDIT 3
Do I need to flash a certain BootLoader along with the recovery for my device (BL and AP) ? , reboot in recovery and flash the custom rom ie "Tekxodus" ?
found this guide for 910C
http://www.ibtimes.co.uk/how-root-galaxy-note-4-n910c-android-5-1-1-lollipop-1518168 with these steps
"Step-1: Download the flashable root package and transfer it to the storage of the phone
Step-2: Download Android 5.0.1 bootloader package. Extract it using any extracting tool and you should find a folder containing Odin flashable tar package and Odin binaries"
so confused lol

All you have to do is Odin stock 5.1.1 rom (COI4 i believe) then Odin TWRP then flash Tekxodus V3.2. Let everything optimize and let it sit there for a good 10 mins after optimization. Ignore what its doing. It will just work. No need to flash anything else unless you want Xposed, then you flash that right after flashing Tek (do not boot in between)

any idea where to get a custom kernel for 910w8 5.1.1 to root stock rom?

Im running this rom (flashed using odin)
http://www.sammobile.com/firmwares/download/56498/N910W8VLU1COI4_N910W8OYA1COI4_TLS/
stock telus rom. I loaded this rom by clicking BL in odin and selecting it (along with my recovery for telus 910w8). This was the only was to get my phone back into working order.
______-
I loaded my recovery for telus into odin and went to download mode.
booted into TWRP
Flashed Tekxodus V3.2.
Optimized apps for about 10 minutes and it just restarted and optimized again and again.
One time it said System UI has stopped and I was hooped.
not sure where I went wrong?
thanks for the response btw I really want to get this going cheers

I337UCUGOC3 bootloader locked, want to update to I337UCUGOK2 to unlock bootloader

I hit on UPDATE on the phone for an OTA update but it only says UNABLE TO CONNECT AT&T SERVER. When I bought it, it had 5.0.1 (I337UCUGOC3) out of the box. Searching on internet says that is bootloader locked (so I cant do anything).
- Can I Update to I337UCUGOK2 and bootloader will be unlocked (I mean, will I be able to do it)?
- Does anyone know where can I grab I337UCUGOK2 for offline install and is it ODIN safe to update it (remember I have I337UCUGOC3 bootloader locked)?
please help

Once the bootloader is locked, it will always be locked until someone finds a way to unlock it. Updating the bootloader will not allow it to be unlocked.

Unlocking/exploiting the bootloader for the AT&T is still in process, I think.
Bootloader locked means you can not install custom recovery like TWRP, CWM or custom kernel. You can still root, you can still use odin and you can still install custom rom using either safestrp or flashfire.
Here is the thread explaining how to upgrade stock or rooted stock roms.
The explanation starts from installation of NB1 firmware so that you can easily root the phone by using twolroot.
If you do not care for the root you can start reading from the step 2 "Flash update in stock recovery"
Since you are on OC3, you need OC3 to OC4 and OC4 to OK2 files to get OK2.

help... I want to RMA it

Everywhere says I need a kitkat rom as base.
My s4 came with 5.0.1 with OC3 and bootloader locked out of the box. I tried some post where says I can flash TWRP and CWM but my phone stucked on bootloops. Then I managed to get back to stock rom and now when I want to turn it on it says " SAMSUNG (and lower on the screen) Custom"
Camera began to fail and I want to return it as RMA but I was looking to reset the flash counter but every post I read is that OC3 bootloader locked users are just doomed.
Do you know a method that I can do for reset that counter?
Camera dont focus anymore and I tried all the posts about safemode, etc.

Flashing TWRP and CWM is for the AT&T S4 with older bootloader (MDL, MDB). After that two firmware versions the bootloader is locked.
For AT&T S4 the last full firmware released is NB1. After that they released incremental updates via OTA. That is why you need kitkat (NB1) as base.
For NB1, Muniz uploaded two firmwares. One is the stock and the other is rootable stock. Try the stock one and see you still have the custom symbol.
To reset the counter, there is an app calls Triangle away by Chainfire. However, it does not work on AT&T S4 with locked bootloader.

Trying Odin-Stock NB1

1st part - Success
I'm on 4.4.2 NB1, flash counter back to normal but still bootloader locked
Now I have to go back to OC3 to RMA it.
OTA does nothing, smartswitch shows no updates neither kies.
I'll have to Odin it back to OC3
Can I have some help?

And Success. I'm back on stock OC3 no root.
time to RMA
- camera still doesn't focus
- boot screen is back to normal but when in odin mode the counter shows 0x1
- sometimes shows "sim card could not be detected" or similar messages and force me to restart the phone (just happend 2 times until now, never happend before)
I followed this thread

Bootloader question

I don't know if I'm in the correct forum for this, but I'm confused about BL's and need a some assistance. I recently went from a rooted stock ni2 4.4.4 rom to CVertigo1's no-bs bpb1 5.0 rom. I have successfully unlocked my bootloader again and flashed TWRP 3.0.0. Everything's running fine at this point. I want to return to stang5litre's 5.0 dev ed rom that I was running when I ran into a camera failed issue, screwed the phone up and odin'd back to ni2 and rerooted. Phone Info is telling me that I have g900vvru1ani2 bootloader version. I thought I needed to be on a 5.0 bootloader to run a 5.0 rom? BOK3 pda and csc versions and bpb1 baseband.
Do I need to worry about the bootloader?
Can I install stang5litre's rom with my phone the way it is?
I'm able to flash in TWRP, and have used odin repeatedly.
Any help please?
Thanks
Don't know how I didn't see this. Can I follow jrkruse's instructions for updating /downgrading bootloader on page one of the bootloader unlock thread?

Bootloop issues

Hello there. So, this is my actual situation: I have a galaxy s4 on stock Lollipop. Due a few issues, I decided to try to downgrade to kitkat I flashed via Odin a stock kk fw, but unluckyly I Haven't considered Knox bootloader, and now the phone stucks in bootloop. I tried to enter recovery, but it doesn't even work.
Is there any way to save it? Actually, I'm downloading stock lollipop firmware to flash it from Odin. Could it work ?
Thanks everyone will give help

Yes, flash the latest stock ROM in Odin to get the phone back to stock.
