Vietnam S6 soft-bricked upon flashing 5.1 update !

I am creating this thread on behalf of @k_kasadze, who was seeking help from me using pm.
It looks like he has soft-bricked his Galaxy S6, whose model no. he says is indeed G920F without any doubt, by flashing the 5.1 firmware. I find it strange, because he did get PASS message on Odin, as shown by the screenshot below.

Can anyone help? As far as I know, you cannot downgrade after flashing 5.1.1. And you can't install TWRP either. Please correct me if one can install TWRP, in that case, he could restore from TWRP. I think he can still boot into download mode.

Ask him, to boot into stock recovery and clear cache + factory reset

When I'm connecting in download mode the smartswitch says that device not supported, samsung driver is installed
factory reset didn't help

What version of odin did you use? Its recommended to use the very lasted version. That made the difference for a guy in another topic

tried a lot of times but I think there is something not flashed correctly. But after finishing the process odin says 100% pass.

SOLVED - bootloop after installation france 5.1.1 on G920F
SO who has similar problem I fixed the problem this way.
1) flashed TWRP RECOVERY 2.8.7.1 via ODIN
2) downloaded custom rom XtreStoLite-2.0-Odex-Pure-ROM-Final-XXU2BOFJ
3) flashed it and my phone is alive plus root and TWRP recovery

I have no idea what to do...
So I'm in the same situation as you, I was doing all sorts of flashing and stuff but something went wrong along the way.
So I have the very latest twrp installed and I connected to my pc, yet I can't move files over for some reason.

OK so I was on the unbranded S6 920F and as the signal was pretty bad thought I would try the H3G latest stock firmware .on Sammobile.
I am on 3 anyway so hoped that using that firmware the modem may have been better. I did the usual and it failed at the end of the cycle same as you.
Did that several times and tried with smart switch, wasted loads of time then tried the first one that was released for 5.1.1(France) and it passed and booted normally.
Not a clue what happened maybe the H3G Rom BOfj was a corrupted file, though very unusual from sammobile.
Edit.
Ironically the signal actually appears better on the france 5.1.1 than befor on AO3 5.02..will update after a few days

Glad to hear another positive bit regarding this firmware on the network reception... I am only holding up from flashing it is root...don't want to trip knox

Changing CSC without root

Is it possible to change CSC with the end result being unrooted? By this I mean if it requires me to root in order to change CSC that is okay, but then can I unroot while keeping the CSC I changed to? The reason I ask is because I want to be able to use banking and other apps (I've read that root prevents these apps from working) but at the same time I want to have wifi calling and voLTE for my carrier.

Right, without root, all you need to do, visit sammobile and download then flash the compatible image from the carrier you want to switch to. However, be aware, of hardware limitations i.e.) you cannot flash a snapdgragon fw on a exynos phone for example.
Now if you had root on the other hand, you can do this in a matter of mins and not loose any files.

I wanted to use a CSC that allows AT&T wifi calling and voLTE. This thread https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264 shows that it is possible to flash USA Multi-CSC using TWRP and root, which includes AT&T. So is it possible to have this CSC on the G955F while being unrooted? If it requires me to root and then unroot in order to change the CSC, I would be okay with that too as long as the CSC stays.
Based on what you said, I'm assuming the answer is no because the AT&T variant is the snapdragon variant, so I'm guessing that means the CSC wouldn't be supported in exynos unless flashed via root and then remaining rooted. Correct?

if you have Exynos phone you got root as an option

Right, but the problem is that with root I won't have access to banking and other apps. So I was hoping maybe I'd be able to root, flash the CSC, then unroot and find a way to keep the CSC. Basically, on exynos, I want to be able to have the AT&T CSC and banking apps at the same time.

i have the 955FD with an ATT CSC and Wifi calling isn't working and i can't visually tell if VoLTE is working. next step is to get an ATT imei assigned to my number to see if that fixes it. bottom line, changing to ATT CSC is not guaranteed to get the aforementioned services working on your 955F.

Root it , fix it and get voLTE then use hideroot to hide root on that banking apps .

What do you mean with "Factory Imei"? It's a menu or something? In phone dialer that code doesn't work...

Same question here what does "Factory Imei"? It's a menu or something?
Also in step 3 assuming you have to put the CSC of the new CSC area you want. Also usually you flash CSC and not HOME_CSC. In this case it is reverse, any reason why ?

i have same objective as yours, i have SM-G9550 which is hongkong variant (non-root) and it is snap with 6gb pf ram and 128gb of rom. I want to change CSC to Thailand (THL) to use VOLTE and VOWIFI. But problem is Thai variant is EXYNOS paired with 4gb of ram and 64gb of rom. So is there anyway to work this without root as i need to use Knox and samsung pay so root will deatroy it correct?

You can change the CSC region successfully using @ngominh's method.
But you have to find "The Combination" file for your phone to do it and that
is usually a "Paid" firmware which is different than your normal stock firmware!
You find that and you can change the CSC successfully!

[Help] Changing Service Provider SW

Hey guys, I bought my s8+ 955FD in Thailand, and no matter what I flash the initial language is always Thai, the Google Playstore is always set to Thailand, what I realised is that the Service provider SW ver in software information is always set TH/TH/TH, is there any way to change this?

Yes there is. Find a CSC package which contains the country language you wish. Make sure the CSC package is for the same version of your overall phone, which if stock may be a 950F, or what ever. flash the CSC with Odin. Do not use the Home CSC from the package, as what will leave your CSC as TH. Some folks have talked about with new phones you need to get a SIM card from the local where the phone was 'meant' to be used, and use if for 5 minutes, so that will effect the 'unlock' ability to be used for other regions. Check into that, as well.
If you decide to change the overall software on the phone, 'F' packages seem to work pretty well. If you do decide to flash an F ROM, you also need to flash an 'F' CSC (multi) package, where you can select the country you wish and the carrier from the install dialogue.
Often the preferred installer for custom ROMS seems to be Aroma, as it is a very flexible installer for ROMs and about anything you can think of to add onto or into a ROM can be incorporated into the Aroma installer.
If you are not going to use a custom ROM, then you will flash a CSC package from Odin, but again, first check to see if you must use your phone for 5 minutes from the SIM local.

I have flashed multiple stock roms with their respective CSC and it does not work that was my question

Have you used the phone for 5 minutes within the originating region?
"Some folks have talked about with new phones you need to get a SIM card from the local where the phone was 'meant' to be used, and use if for 5 minutes" . . . in order to functionally unlock it for out of the region use. Is your software that version?
When you flash the phone, what SIM is inside the phone before the reboot?
Are you rooted? If so flash via TWRP and a CSC which has an Aroma installer.
What else can you tell us about the specifics of your phone?
If you re-flash the OEM firmware, or when your first setup new, do you get any language options on the start setup page, besides Thai?

Dear Jeff, thank you for the help and the follow-up. I have managed to change it partially by inserting a new SIM from the new country(Brazil) and when I did so, it asked me for a reset and I went through with it, now it's ZTO/ZTO/THL ---- so the first two changed to Brazilian CSC but the third one is still THL, any thoughts? what's the difference between the 3? And yes I had used it for a lot longer than 5 minutes when I was in Thailand. I just want to get a clean install without any remnants from THL - I am currently on CRAP/CRB7 - Waiting the 7 needed days to get OEM unlock and be able to flash TWRP(from what I understood), please tell me what to do to get rid of the THL from my phone completely. Thank you So much

Once rooted, find a multi-CSC package with your country and flash it (again). You might need to flash the baseband, so I'd look into that, as well.
On an S7 from with a Chinese CSC, once I found a custom ROM, , I flashed TWRP in Odin, booted into TWRP/recovery, flashed the custom ROM, verity and SU, and then flashed a multi-CSC package Aroma package, mine lost all the Chinese info.
Sure would be great if these phone companies would just give us unlocked phones, with straight forward methods to make these simple changes. I think most folks would pay a little extra for the ability.

Hi Louayd. Did you fix this issue?
I'm passing the same problem with S9+. I bought in Portugal and trying to use in Brazil. I can't root phone because my intention is use the Samsung Pay and it with rooted phone it doesn't work.

I am facing the same issue. I bought Note9 from Singapore from M1 Operator. I have flashed different countries ROMs but my phone always keep some bloatware from M1 Singapore and the "Service Provider SW Ver" always show MM1/MM1,MM1/XSP despite whatever country/region Stock ROM I flashed. My phone is already OEM Unlocked.
Need support if anyone has managed to change it.
I do not have Original Country SIM to test as mentioned above. I bought it from Singapore and wanted to use it in Cambodia. Right now VoLTE functionality is not working.
I tried to use ShortcutMaster app also but it is also not able to show anything under IMS Service and Settings.
Regards,

Galaxy S7 Verizon phone unlocked

I bought a refurbished phone off ebay with the Verizon logo on it but unlocked version of android without Verizon software and wifi calling. Was phones sold new with the Verizon logo and unlocked version of android? Does the GS7 have wifi calling for Verizon? I can't find the option in the settings. My G6 has wifi calling.

To my best knowledge only the G930U (non carrier) comes from the factory unlocked, if yours is Verizon (G930V) it would have sold new as locked on Verizons firmware, and someone has unlocked it afterwards.
They should have VoLTE and VoWIFI, you just need to make sure your carriers CSC is flashed on the device. If it's refurbished unlocked it's probably on unlocked CSC so won't have any carrier features.
Try getting the latest firmware package for your carrier from sammobile.com or updato.com, and flash ONLY the home_csc via Odin.
All US models are the same SoC, so even if your phone is the Verizon version, you can flash any other carriers firmware.

Thanks. I have another question. Will the unlocked version be better to have and will it get Oreo sooner then the Verizon version?
I haven't flashed a firmware before. have some links bookmarked for doing this to this phone. I guess i would have to reset my phone and reinstall everything.

I would expect the unlocked version to release first since the firmware doesn't have to go through carriers own changes and verification, but that's only a guess.
But since the SoC is the same, you could technically flash the Oreo firmware from whichever phone gets it first, you'd just have to put up with the carriers bloatware.
There's a good flash guide on updato.com for Odin, from memory if you flash all files using home_csc and it's the same version or newer it doesn't wipe. But I've never tried it that way myself.

here's what my about phone screen shows. Would that be stock or flashed by the seller or whomever? It shows my phone its the U version instead out the V version.

Boot into download mode and check, the phone information page will be wrong if the phone is flashed with firmware that's different to its stock.

I finally tried to flash the files and using home_csc but it still says 930U and the software is still the BRC1 not the BRC3 and the settings menu isn't the verizon style. I'm not sure what changed. the flash was successful though.

You might find the stock CSC needs to be flashed for those changes, since it triggers a full wipe. I'm not sure the model would change either way.
So long as you get the functionality you want you should be fine.

It has VOLTE enabled in the settings. is that HD Voice for Verizon?

Yep, from their faq:
"HD Voice is a suite of services enabled by VoLTE (Voice over LTE) technology. VoLTE delivers voice calls over the 4G LTE network instead of the traditional voice network, providing clearer, more natural sounding audio when both parties are using HD Voice-enabled phones that are connected to our 4G LTE network."

I can't remember if the setting was there before. Does all the unlocked versions have that feature? I don't think i had it before because my phone signal is weak and mom says I cut out when i move around.

I believe it's only there if you have the CSC of a carrier that has it enabled, it's not there on mine at all for example. But I have a G930F which is international, different SoC and firmware.

Wait I got confused. I was thinking of wifi calling when i was posting last night. I made a phone call today and it was waiting for a good signal before dialing. Any ideas? I was hoping to use wifi calling since i get a weak signal with this phone. my LG G6 got a stronger signal in the same spot at the computer desk then this GS7. The G6 has wifi calling in the settings but not this phone.

Since I don't have the option myself I can't tell you where the setting should be, but these might help. They're technically different services, so are enabled separately.

Since I'm on the unlocked version I don't have the Verizon style setup menu so I can't find it. I don't see Wifi calling in the settings at all. I do find a Smart Network Switch in the advanced settings for the Wifi. is that the same as Wifi calling?

(fixed S7 typo)

You will need to flash the Verizon version of the stock firmware (SM-G930V) in order to get VoLTE and WiFi calling on Verizon's network. Every carrier is different, and this is usually one of those features that require their own firmware build in order to get it to work. If you have the Unlocked version (SM-G930U) then Wifi call may work on other carrier's networks, but it won't work on Verizon.
I'm currently using a Verizon purchased S7, that I flashed to the Unlocked version SM-G930U. Wifi calling works for me because I'm on T-Mobile's network (with Mint Mobile). If I inserted a Verizon SIM then I wouldn't be able to use their Wifi calling without flashing the firmware back.

Congrats. But FYI, the only reason you were able to do it so easily is because you were flashing a "Stock" firmware, direct from Samsung and signed by them. You can flash any US stock firmware on any other US model of the Galaxy S7 (the Qualcomm version). So it's really hard to mess up. Flashing any of the "custom" roms in the other threads is an entirely different animal, and not something I personally recommend unless you are truly motivated and know what you are looking for. Lots of opportunity for error, and requires workarounds.
The point I'm getting at is you'll likely get the official OTA update around the same time you would find a version that you would flash, because they come from the same source, and are the exact same files.

Question [SOLVED] M127F stuck with Russia (SER) CSC after flashing Brazil ROM and later trying to flash back to XEO

So I wanted to try something so I flashed the Brazil ROM. tried to flash back to XEO but now in the settings it says "SER/SER,SER/XEO" and when resetting installs Russian bloatware. What can I do to restore the XEO ROM?

That is weird. Full Brazilian stock firmware set? AP, BL, CP and CSC_OMC_ODM? Once the device is restarted after flashing get into the recovery straight away (hold power + volume up with the USB cable connected to PC). Don't let it boot Android! In the recovery do Factory Reset, format the data partition (if it's possible in the stock recovery, I don't remember) and wipe all the caches and only then boot the system. Also try removing the SIM card before flashing and also do the first boot of Android without SIM (although it shouldn't matter but who knows).

I remember that when I did disassembling of the Prism partition of different country versions I've discovered that most of the European firmwares contain the full set of Russian bloatware. In fact, all the firmwares with the size of more than 5 GB are all nearly identical in regards of bloatware included. So I can suggest you to temporarily install a Nepal or Papua New Guinea firmware, do the factory reset with it, go fully through the setup process, and then try again to flash the Brazilian version. It may help. Or you can stay with the Nepalese firmware, it's quite minimalistic and includes Samsung Pay (if you need it).

ok but the m127f model doesnt have a nepal or papua new guinea firmware

Try Bolivia: https://samfw.com/firmware/SM-M127F/BVO
The general rule of thumb is the smaller firmware is the less bloated it is. Also prefer firmware for the poor and commercially unpromising countries, the so-called "3rd world".

sorry for reviving this thread but is there a way to get lte back? all i want is "good" mobile data and lte works good on my huawei, so can i get it back on my samsung without somehow changing the csc? (the carrier i use is Play in Poland)

after around 8 months, today i finally got my lte back via the samfw frp tool
