I used those 2 threads trying unlock my L720, I followed everything up and It went smoothly It worked with (Simple mobile & Straight talk att sim card) but I was not getting a constant service, decided to go back to sprint and then, just trying to go back to stock firmware!
I am getting "Firmware upgrade encountered an issue.." in Odin every time that I try MDC, MK2 Stock firmwares says "FAIL! (Auth)" ?????
The only tar that is working is MDC modem tar found on the 1st thread used to downgrade modem to MDC, even though I was in NG2 which is the latest i was stock and rooted!
Then the phone boot up there's no sound no WiFi touch problems or is it the phone is really slow!?. I did a factory reset and nothing!
Another thing, but I noticed this since unlocked it! there is a picture too! Baseban and build are different!
Please any help would be appreciatte it!1 Thank you!
Hello,
Just bought a topaz blue unlocked S6. I think it came from an Asian country. The phone arrived perfectly with plastic in box with the same IMEI as phone. However it was rooted with SU. I went into the app and clicked to remove root. It was on 5.0.2. They I tried to flash original firmware with Smart Switch with no success.
I used odin to flash stock 5.1.1 firmware from the UK. The firmware was for 920F. It went all good. I have LTE, SMS and phonecalls. However, sometimes the baseband appears as unknown, but I still can make calls and have LTE. And it still shows the same IMEI as it is on the box and it has always shown it. Is there a way to fix this? Now, I try to flash stock firmware with Smart Switch and it says it can't initialize.
I would REALLY appreciate help. I would love to be able to flash stock firmware from Smart Switch.
I'm in México with Telcel, which uses the same bands as AT&T.
P.S. I really searched and couldn't find anything on my specific situation.
That happened to me when I was still on 5.0.2 and flashed only the 5.1.1 modem. I would suggest downloading the modem.tar file and flash that. Should all be good after that.
I'm currently downloading G920FXXU1AOD4 BTU firmware to flash it with Odin. Might that help me better? My main goal is to be 100% stock without any weirdness. And having Smart Switch recognize my phone!
Well, I'm sad.

You cannot downgrade to 5.0.2 from 5.1.1. Your bootloader will not support. I have the issue with 3G connection. Where to get the Modem.tar?
I have really made a mess trying to fix it myself.
I will write the current status and at the bottom what I've tried so you can skip
Model: sm-g920f
IMEI: 359845066450254
sn:RF8G41WR1SW
Android version:6.0.1
build #: XtreStoLite Deo Mod v.3.3 - DPDP
Baseband:G920FXXU3DPDP
Kernel version: 3.10.61-7884513 [email protected]#1
22 Apr KST 2016
now the sim card works in other phones and when I remove it the device registers it is SIM CARD REMOVED but when I put it back in nothing happpens, and mobile networks settings is gone
*I started in stock 5.1.1 (MADE NANDROID BACKUP OF EVERYTHING INCLUDING EFS) and flashed twrp via odin > (everything still working)
*flashed XtreStoLite 2.4 (5.1.1) via twrp > (everything still working)
after several months
*flashed new 6.0.1 bootloader and modem via odin and tried to flash XtreStoLite 3.0 (6.0.1) via twrp > got stuck in bootloop...
*used smart switch to go back to stock 6.0.1> Everthing was OK until about a month later the phone suddenly restarted and doesn't recognize the sim card
* I tried factory reset
* I tried samsung but they gave it back saying I've tripped my knox flag
*I flashed 6.0.1 XtreStoLite bootloader, modem and TWRP again via odin
*I flashed XteStoLite 3.3.1 (6.0.1)
*I tried restoring from the first nandroid (stock 5.1.1 from the begining) and got stuck in bootloop again.
*reflashed XtreStoLite 3.3.1 (6.0.1) and tried restoring only the efs. still doesn't work.

I saw some threads talking about octoplus box but I still have my efs Backed up my and SN and IMEI still show up.
Please help me I am here I am willing to learn and search online. I've tried everything i've found online.
Hi.
Try to use Smart Switch > Software Update and Initialization to recover your firmware, hopefully you get your network back.
Tell me what happens, gl.
Sent from my SM-G920F using XDA-Developers mobile app
almost same thing on a long thread here, no solution so far:
http://forum.xda-developers.com/galaxy-s6/help/g920f-network-issues-t3291903
I am seriously considering it could be sim reader issue, or some cold solder somwhere on mbo.
My IMEI was also showing in settigs, but when dialed *#0011#, in stack 1, there was "IMEI NG", after write cert operation via octoplus, it says IMEI OK now, but NO SIM, and no mobile networks menu still.
Same like you SIM is detected when inserted or removed, and phone offers restart to access mobile networks, but after restart nothing changes, KNOX tripped by previous owner, phone was in three 3rd party repair shops, where they made even bigger mess than it was, when I brought it to them.
i had the same issue when i upgraded to mm so i sent to shop they had to downgrade it to 5.1.1 and use octobox to fix it
Thanks for replying Legend.
But even though I did the software Initialization in smart switch once before it is not working for me now.
I've tried twenty time while reinstalling and restarting the pc I even tried a different pc I get the same error message every time. "failed to run firmware upgrade unknown error occurred".
any other thing to try?
you could try to restore that backup you have, from when everything worked and then flash 5.1.1. bootloader and modem for that csc via odin before rebooting
According to Smart Switch with your sn it is ILO so you need 5.1.1 bootloader and modem from ILO 4 file fw package.
*I just managed to flash stock 6.0.1 via odin (even though It failed at hidden.img... it boots normally) still no sim card tough.
*I realized that maybe all of this happened because when I flashed stock via smart switch for the first time I didn't have my original s/n so I put one from the internet and it wasn't my region.
meaning I flashed stock of UK and it still worked for a month or so, so that's weird...
*Thank you brenner that is a good idea and I will try now
question how do I extract the bootloader and modem out of the fw? I just open the tar archive and take the boot.img and modem.bin files and flash them as is?
nvm found a guide

There are .tar-s which are single file, and 4 files, the ones with 4 files has separate bl/modem
btw, isnt sn written on back of the phone, along with IMEI?
OK, I've flashed the nandroid stock 5.1.1 (LMY47X.G920FXXU3COJ1) and its bootloader and modem from sammobile.. still doesn't work!!
How can this be? everthing is EXACTLY the way it was when it was working!
and no, my model at least doesn't have the S/N and IMEI written at the back, and I didn't keep the box
any other suggestion anyone?
*also there are so many post in subject if I ever find a solution I will make a guide.
-bump-
still no solution..
I've flashed back to current stock ILO...
Meanwhile looking for a lab with octoplus box, still would love solving this at home
At home or not, I would like to solve it too
Bought a second hand S6 the other day and was working perfectly fine until I carried out the update. Now on 6.0.1 and am getting the exact same problem, my SIM works in every other phone. Has anyone found a solution for this?
Not that I know of, except hw replacement, which cost as a used phone with 1+ years of warranty (6 months warranty on motherboard after replacement, on motherboard only)
But I am willing to donate to whoever finds a solution for it.
No i think your problem is a S/W problem, i have 2 G920F with this problem, one of them is 3 binary and another is 4 binary FW, now i work on it if i can solve this problem i told you here.

Hi community,
A question for many of us in regards to 'unlocking' or "how to unlock" from our carriers, I have done a very simple and silly way to unlock my phone from T-Mobile.
I am currently under SM-G935U Firmware (4API3), coming from SM-G935T's 4APIA Firmware.
Follow these simple steps in order to unlock from your carrier.
***NOTE: THIS METHOD ONLY WORKS IN STOCK FIRMWARES. YOUR DEVICE WILL BREAK IF YOU TRY TO INSTALL UNDER A CUSTOM ROM***
1.- If you have previously installed a custom ROM (Echoe, Tekv2), say bye bye for now. Using Odin latest version (3.12.3), flash Stock Firmware '4APIA'. After set up enable developer options and USB Debugging.
2.- Download SM-G935U's official firmware from SamMobile or Samsung-Firmwares (Make sure you download the TMO region firmware)
3.- Create a new folder on your desktop, copy and paste BL & AP files from the SM-G935U firmware you just downloaded. From the SM-G935T stock firmware you downloaded, copy and paste CP & CSC_HOME files.
*Basically you will have BL/AP from G935U and CP/CSC_HOME from G935T*
4.- Flash these files through ODIN, but WARNING: After flashing your phone will reboot. Go into recovery mode and wipe cache/data + wipe data.
5,- You will get to see a dm-verityverification failed, no mount blah blah blah. Just ignore it. After deleting cache and data reboot again into download mode...BUT THIS TIME ONLY FLASH CP file from G935T while the CSC_HOME you will flash now will be the official G935U file.
6.- After reboot, done.
I was able to install Google Voice
Sounds promising going to try this when I get home, was having all those issues with dm-verity.
Have you tried just wiping the cache and not wiping data with success? (Dirty flashing)
Or we all starting from scratch?
since root with eng kernel makes my phone burn up and kills my battery, even with all the remedies. The g935u is an option I would love to play with.
But how did you unlock the sim? You have the unlocked versions firmware so less bloat and no carrier garbage but the phone itself would appear to still be locked to TMO. Splain.
Hi there. This firmware is so much better than the stock TMO firmware, everything works excellent. I used stock tmo firmware first APIA, next tmo G935U API3 next. I tried your way first on a S7 Edge with bad IMEI and it wasn't working. I used another S7 Edge but this time I flash all the G935U API3 firmware, it work flawlessly with one simple try. Just put AP/BL/CP/CSC and flash with the latest Odin, you wouldn't have problems. My 2 other TMO S7 Edge are on stock G935U and saying official.
Hey can make a video like you did please.

Yes indeed it is. G935U feels great, faster response, no lag at all and for some reason I get 4G LTE even with Roaming (Mexico) I am still with T-Mobile...were you able to UNLOCK the SIM?

Hey bori,
Every time I flash a custom ROM or even going back to stock, I always wipe cache/data. It is just the way I like to do things on my phone, not keeping any traces from previous ROM/FIRMWARE.
Make sure you download the official Firmware from SamMobile or Samsung-Firmware.
I heard updato is a fast download Firmware site.

Well i tried last night but ended up with the same results. Goes perfect in Odin. But boots straight into recovery even though I wiped everything and reflashed cp and home csc from g935t files.
For the TMO and other SM-G935 firmware, check out THEANDROIDSOUL.COM . They have about 90% of all firmware.

I'm not a big fan of stock roms, custom is the way but this TMO G935U FIRMWARE IS THE ****TTT !!!.
The last time I used a stock Rom was from HTC EVO 4G, after that was the Sprint S2 and I never USED ANY PHONES WITHOUT A CUSTOM ROM TILL NOW.
This TMO G935U FIRMWARE, I did a ANTUTU BENCHMARK LAST NIGHT after flashing the firmware. Mennn! The score was higher than the note 7 N9300 by 4000 points, I couldn't believe it. I did a second test samething. The battery performance is excellent.
All mine said was applied multi csc now I get lte+
Nah I didn't try to unlock it yet, I have to get an AT&T sim card or simple mobile card and see if it ask for codes. If that works that will be great for everyone ?.
Which U firmware are you guys flashing and what would be the differences between them? I'm currently on the T-Mobile U firmware.
tried this... asks code also ... but anycode can give message "network successfull".
BUT its not unlocked... still "invalid sim card inserted error" is there.
So this method works or not? I want to know before I take the plunge. Also Dm verity error doesn't sound good either. I had a note edge with that error and it was a major headache.

i was able to flash g935u firmware totally.. but didnt work for me.
Hi all. As far as I can see, the U firmware unlocked the phone. I inserted a SIMPLE MOBILE CARD into my G935T running G935U firmware, the phone boot into like recovery mod but the screen go BLUE and it configures SIM UNLOCKED SYSTEM, then it reboot and walla the phone have service on SIMPLE MOBILE NETWORK. I was very SURPRISED it works because the phone is locked to T-Mobile and only the DEVICE APP to unlock it. So at this point I'm only using the G935U firmware on my G935T, no more T-Mobile firmware bull crap. Next I'll get an AT&T SIM card and try that for 30 days.

No matter what I do I cannot get my phone to go into the Samsung sim unlock screen after flashing in various combinations, including following the OP exactly

I know this is a late response but it's good to know. SimpleMobile has been running under T-Mobile Network, whether your T-Mobile Phone is locked or unlocked it will work when a SimpleMobile Sim is inserted.
network unlock code????
Hey all! I have a Sprint S8+ and I've flashed a G955U1 firmware on it. The issues I have is my GPS doesnt get a good lock and acts weird/slow and my service will go in and out multiple times a minute in certain areas. Ive update PRL and even used the## code. I'm stumped and cant find stock sprint firmware
i too did the same thing and am not haviing any issues. first, i would maybe do a factory reset. then if you really jsut wanna go back to stock sprint orignal firmware, here ya go: http://fws02.updato.com/GALAXYS8+/SM-G955U/SPR/SM-G955U_1_20170731114139_f586saxigh_fac.zip
remeber to use that modded version of odin to flash. the regular version wont work.
