I have a note 2 from AT&T which is unlocked but no signal at all. I have tried all solutions: write nv items, unlock by Z3X( failed ), flash original firmware, ....
I was told i need a good nv items from a working phone to get it alive. Pls help me
I am trying to setup my sprint note 4. I successfully unlocked it using my z3x and ti will detect the network and does not show invalid sim. However I get a Exclamation point on the signal bars. When I run sprint hands free activation I get the network name, 3g data, and network status without issue. As soon as I close it it goes back to the network error.
I have been able to kill the activation at just the right time and its stays showing 3g, network name, etc. However when I reboot it will go back to the same. I have tried this process of making the network stay on and then renaming the Sprint Hands free activation apks and rebooted but the problem persists. Its like the activation or something on it is intentionally killing my network. I have also tried flashing a different modem and resetting network settings using ##72786# and also enabling GCF as advised from the secret menu. Pretty much at a dead end here hope someone can help.
Thanks

First of all you have to unlock it again from z3x because you did dial ##72786# this will lock the network to domestic usa carrier only.so now your phone is unlocked but domestic only.
You have to choose "unlock" from z3x again not "unlock domestic" after that dont play with hidden menu or "scrtn" just dont put network mode on global you have keep on gsm/umts network will work fine.and you have to set Apn manually for mobile data.
Or my best suggestions is after unlocking from z3x once you get network fine flash twrp recovery from odin then flash tmobile rom from twrp i will give you in link below.
The device will work flawless without all that sprint headache.your apn will set automatically and 4g will work too but no LTE.
dont flash any kernel just flash rom then reboot and wait 10 minutes to boot.
Tmobile rom

You have to flash tmobile twrp recovery via odin if you flash n910p sprint twrp this rom will not flash.

First of all thank you so much for your response.
I got the rom you listed flashed and I am getting network bars. However the network just shows searching and will not register. My options under network are LTE/WCDMA/GSM and WCDMA/GSM and GSM only. When I set to GSM only I get no service so its definitely not registering if I understand correctly. I am trying to rerun the unlock but I cannot get any promps for root access or usb debugging.
I also am really curious how flashing the Tmo rom worked considering its QI5 to QI2. But I am obviously learning still.

First of all you have to check your imei and S/N dial *#06# see if it match same as sticker behind battery if they not match you have to repair imei by z3x same as in sticker behind battery.try "patch certificate" in z3x repair tab to fix network error if it doesn't fix try write imei & s/n manually.
You dont need root for unlocking just dial ##3424# then go to qualcomm usb settings then choose DM+MODEM+ADB .
Now go to z3x and choose your model n910p then click diagnostic mode.
Your device will reboot then you can unlock from z3x without root.
You must be on n910p firmware to unlock it will not unlock if you are on tmobile rom.
If unlocking fails try with "uart cable" if still get error then you will need to temporary flash ENG BOOTLOADER ROM from twrp then you can unlock from z3x without errors and you must have z3x v28 or higher.
This QI5 bootloader/baseband is so complicated to repair stuff.
Let me know if you want ENG_BOOTLOADER ROM.

I have been able to get to the tmo firmware, eng firmware etc. The serial is definitely zero'd out, but I cannot find a way to fix it. All of my apps show it greyed out (octoplus z3x). There is no patch cert area in z3x and s/n is greyed out in octo. I did manage to completely kill the radio to where I got nothing but thankfully I had a backup of the NV EFS etc most of which I know very little about.
Edit: the meid matches the HEX on the back however the IMEI has a few extra digits on the end. Not sure if this model even has a S/N
Edit 2: This model does not have s/n. After repairing cert and doing the regular unlock in z3x and flashing back to Qi5 stock I was able to get it to work. What threw me way off was I had to enter APN settings for the carrier before I was able to connect. Using the T-mo firmware resulted in lag and overheating. I am not sure why.
since i update my n910p to qi5 there is no network(no signal bar) on my device i have flashed SM-N910P-PB5-ENG-ROOT-TWRP-FLASHABLE .zip on qi5 rom and also flash auto root for n910p for root access so what should i do to unlock my network???? i have z3x 29.5 craked version according to z3x instruction usb settings is on dm+modem+adb when i call *#9090# that's what i see:
service mode(on top of screen) and following is
diag config not support!!!
so i can't choose 'DM/DUN over HSIC according to instruction and at the end
when i click to unlock this is my log :
Reading phone info...
Reading IMEI... OK
IMEI: 99000.....87929
Unlocking... error (02)
Done with Samsung Tool PRO v.29.5
my imei changed and is not the original and i should repair it but when i enable imei in the z3x settings nothigs happened and no imei repair option on repair menu help pleassssssssssseeeeeee :crying:

FOR SURE QI5 SYSTEM YOU WILL GET ERRORS IN Z3X.
YOU MUST Flash "ENG PB5 ROM" FROM TWRP AND ROOT WITH SUPERSU then PUT PHONE IN DIAGNOSTIC MODE AND unlock via z3x it will work without errors then flash back qi5 it will remain unlocked permanently.
THIS "ENG PB5" ROM IS SO BUGGY AND IT WILL TAKE LONG TIME TO BOOT ABOUT 25 TO 30 MINUTES SO BE PATIENT.

Convert your T-Mobile (LE2127) to EU via MSM, No unlock.bin needed!

As mentioned in this website, I followed all the steps and converted my Op9 pro tmobile to EU. I was on OOS12 so I did unlock by b-loader using unlock.bin.
After I successfully converted to OOS11 EU, I did a full update directly to OOS13(EU). The sim network shows up and I can make a call / receive it. The only problem is the mobile data is not working. It shows E or 4g sometimes for couple of seconds and then it stops. Even the network coverage is lower(only 1 or 2 sticks) than before. The 5g is not working at all also I have selected the mobile network on 3g/4g/5g as I did before. (There is no 5g signal and other signals are weak.) Help me

Firstly, what version are you on now? Exactly which one. Some users are reporting later builds of oos13 EU aren't working with network data and they have rolled over to Global instead. If you're on the latest ota, it seems to be happening there.
Secondly, are you able to find Volte in the settings? Turn it on then off, then on again and leave it on. I suggested this fix for someone else but they said they could not even access the volte setting anymore. This worked for me when I was having trouble staying on (oos11 Tmo->oos11 EU->oos11 Tmo->oos11 EU again (this is where it started, the first flashes were fine)). In some remote areas I would get on LTE but anywhere in the city, I was stuck on Edge and constant looping of it trying to get to lte/5g. Until I toggled volte on/off/on and left it on
