So, I bought a refurbished unlocked S6 the other day (SM-G920F). I didn't note down the original region on the original TouchWiz, but I do know that it was on 5.1.1. At this point the phone was completely normal. I went to install twrp, which went ok, but after installing twrp, the phone would no longer boot, even though I made no modifications to the stock rom. I then decided to format and install a newer TouchWiz room, which required I also install a "kernel". After installing the kernel, all x axis inputs were inverted and the phone still would not boot. I then decided just to download a France region stock rom for the G920F and flashed it via twrp, which was successful. But for some reason the x axis is still inverted and my imei is completely incorrect. I have tried to use the dialer code, but it does not work because of no network connection. I cannot connect to a cellular network because Android has the wrong imei number. I have also tried to use both kies and smart switch but my device will not show up. I also tried an older version of smart switch for the initialization feature, but it says that the g920f firmware is not supported. If anyone can help me try to at least get my s6 back to stock rom without these issues I'd really appreciate it. Thanks!

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 a galaxy s6 s-mg920r7 I recently downloaded a apk twrp 3.0 and flashed to it which caused soft brick I can now only get to download mode. When go recovery it loads twrp up fine but touch screen doesn't work if try boot up normally it bootloops any suggestions be really appreciated

INSTALL BACK TO STOCK THEN use the cf auto root download this use google to search first one that comes up use that link go to model sm-g920p cspire and sprint uses
the same network . Use odin to install i have same phone and have mine rooted in this way. So far tried using the sprint version custom rom it will work but you can make phone calls but not the data side for phone internet. Make sure you go to settings in the phone under find my phone and turn off activation lock
After installing a custom ROM on my galaxy s6 it would no longer recognize my SIM card. I did wipe every option in TWRP recovery before flashing the ROM which might have something to do with the issue. The phone states "No SIM Card - No Service" in the top left of the lock screen, it also wont let me call any numbers to edit things in the phone. I have done some research and it sounds like I have wiped the sim and lost the IMEI/EFS data and therefore no longer have access to my sim. I was wondering if there was any possible fix or should I just send it off to Samsung to get repaired?
Did you back up the EFS partition, and put it somewhere safe? If not, you have a paperweight.
Repair won't be covered under warranty.

Unfortunately I didn't back up the EFS partition. Situation is looking bad. :l
Try dialnig *#06# and see does it shows IMEI and sn, alo try *#0011# select stack 1 and check whether IMEI is OK, or NG.
Also what does it say in phone settings under baseband? Do you have mobile networks menu in settings?
You can try Smart Switch emergency initialization with sn of the phone if IMEI is ok (it will install latest stock fw for your phone) and see if that helps.
When I typed in "*#06#" The SN number was shown however the IMEI number was not. When I typed in "*#0011#" There was nothing but blank spaces separated by grey lines, I tried selecting row 1 however nothing happened. My base band version is "Unknown" listed under settings. I do however have the network settings listed in settings. In Smart Switch when I try to run the device initialization it states that my s6 "doesn't support initialising". I have flashed three different downloads of the stock rom to my phone using ODIN and have had no luck with any of them.
well Smart Switch always says that S6 is not supported, but initialization can be done anyway, just dont connect the phone until it asks you to do so, instructions below:
http://forum.xda-developers.com/galaxy-s6/help/how-to-smart-switch-emergency-t3383448
What is your model anyway, do you know which region fw was originaly on the phone, and which sv rev is shown in the download mode?
does in recovery mode says anything about DRK?
Unfortunately Smart Switch says that "'SM-G920F' does not support initialing. Please contact out service center." Even when I have entered the correct S/N and device model, as well as not plugging in the phone. My device model is the SM-G920F. I don't know the original region FW that was originally on the phone, however it was purchased in the UK and that is where I am have been ever since I bought the phone. The SWREV is: "B:3 K:2 S:2" in download mode. I currently have TWRP recovery installed so is there a place for me to search for the DRK in TWRP? Or should I re-flash the stock recovery using Odin?
that is weird, I reinitialized my g920f many times without any issue. DRK error is usually shown in stock recovery. does the phone boots up with stock fw, and are you using any custom kernel?
i got the same problem when I flashed xtrolite and alexis custom ROM on my S6, both ROM after flashing I got no service.
But I did a full stock backup in TWRP.
baseband unknown means that there is a problem with modem part of fw. and I dont know what fw you flashed. you said that you tried to flash stock, but it doesn`t work, but a little more details would maybe make a difference, like which fw, and what exactly is happening, what does about the phone menu says.
So far, since baseband is unknown I would try to flash modem fw with odin (for exact fw that is in the phone). before that usb settings should be set to CP, by dialing *#0808#
or if you decide tu run custom fw, you can always try asking in that rom thread, maybe someone already had issues like that with that rom and fixed them, or the developer of that rom can help fix it.
Boot your s6 to download and flash stock rom via odin from samsung it maybe work
I recently received a T-Mobile Galaxy S6, and it was rooted and had a custom kernel, which was a complete mess (the person who owned the phone previously clearly did not know what they were doing) so I just wanted to restore it back to full stock.
I am decently experienced with ODIN, rooting, custom firmware etc, but I have just done one of the biggest rookie mistakes I have ever done. I had accidentally downloaded the most recent firmware for my G920T, not realizing that the file was not for T-Mobile. It was the (XAR) carrier (I believe that is C-Spire but i could be wrong) and the latest was PK1.
It flashed perfectly and all seemed fine until I decided to unlock the device. The T-Mobile S6 requires the use of the "Device Unlock" app and since I had flashed the wrong ROM, the phone thinks the Device Unlock app is not compatible. When I put a different GSM SIM card in the phone, it prompts me to use the Device Unlock app.
I do not have a previous NANDROID backup from the original T-Mobile ROM, and now that I am on the lastest Bootloader for XAR, it will not let me downgrade. I have tried flashing pretty much every MM bootloader and TWRP for both T-Mobile and XAR and none will work (except for what is currently on the device of course) I always get the error "Device: 5 Binary: 4" (sometimes the binary is 3, depending on which version of MM rom or BL I try)
To sum it all up, I am on PK1 (latest for XAR) and I need a way to get back to the official T-Mobile ROM (latest is PD1). Is there a magic method to get this figured out or am I pretty much stuck with what I got until T-Mobile releases an update that is PK1 or higher?
Thank you in advance to all of you that take your time to help (and I am sincerely sorry if I am posting in the wrong section)
I am facing a problem. I was experimenting with THE GALAXY PROJECT rom. I turned on developer options and removed oem unlock.I installed twrp for hero lte and did format partition instead of wipe and installed the galaxy project rom. It worked fine but then I revereted to my stock firmware with ODIN. I noticed that I am not able to call any one. I thought i had installed England Firmware on Indian firmware as I faced that problem, so I downloaded the indian firmware again but again it was working on england firmware. I can say this because it was using upday instead of samsung briefing. I thought its a wrong rom again and to atleast make calls installed herolte rom. Same problem. Call ends immediately. My sim works fine in another phone. Any other sim stops calling in my phone.
Can any one suggest a solution of what might have happened.
I just booted into recovery and it mentions there herolte recovery.
Any solution.
Post Note - Rom were fine. Only calling and sending sms is not working. I can receive a text and can use internet over LTE. System cannot read sim phone number in hardware diagnostic. I cannot open aditional setting in phone as it says that error reading sim card.

Reinstall original England rom using Odin. And then install twrp and again install TGP or any other OREO rom you like.
Don't forget to format data after installing tgp for the first time.
Also boot up and reboot once after clean flashing with Odin.
Then flash twrp.
P.S try flashing csc selection by tkkg it may help.
Also which rom are you using nougat or oreo?
I have used Oreo as well as nougat. Problem persists.
Only my current operator aim are not working and rest of the sim are working fine. Service center haa asked me to get motherboard changed.
I was installing indian rom. Now even samsung knox related apps are not working.
So basically you want me to install tgp again and twrp after that and again went back to stock after that.
Do you have any idea why this problem could have been causes. Can rooting mess with physical hardware of phone?

Okay then phone and SMS probably won't work, cause I guess the Indian version is still a nougat but the England one in oreo both your modem and firmware would have been updated and it's not possible to go back, so I suggest you stay with TGP for a while until official oreo arrives in India.
Or else don't use phone or messaging ?
