Flash using Odin loses sim unlock? SM-N920i

Hi, im experiencing some weird resets when i recieve calls, i reset the note 5 like 3 times and still the same, so i downloaded the NZ rom from Sam Mobile and i was wondering if this phone i bought is sim locked and i flash the new rom i will lose my unlock??
Is there any way to know if my phone is factory unlocked or if its locked whit what company?

Ok I find the question a bit strange but will answer to the best of what I understand. If you want to find out if your phone is unlocked just pop in another sim from any other provider and see if you get service or even if it even attempts to find it. If you get invalid sim msg or something similar you are locked. Also to answer your question to which carrier is it locked, that's obvious as it would be the carrier you are currently using. As far as flashing a rom from a different model note 5, I won't recommend without extensive research as you could brick your phone.

Sorry for my bad English, the phone is already unlocked but idk if was manually unlocked or factory unlocked because im from Bolivia and the Note 5 Says spark(NZ Carrier) and accepts any carrier, the problem is my fear of losing the unlock after the flash is this phone was manually unlocked

Help unlocking G920T to Metro PCS.

Hi guys, I have been reading for days but can't seem to find a concise guide. I am trying to use a Metro PCS SIM card in a locked TMobile S6.
I have installed twrp and root through Odin, but I can't manage to download the G920T1 firmware anywhere without it failing and forcing me to pay. I have tried sammobile and others.
After I flash the G920t1 firmware will his metro SIM card just work or do I then have to do a SIM unlock as well? Do I use a TMobile or MetroPCS unlock code if I need to SIM unlock?
Also does anyone know of a ROM that will allow me to use his Metro SIM without any of the above nonsense? I downloaded a ROM but I only have my Verizon SIM to test and it asked for an unlock code.
Any help is appreciated. Thanks in advance!
EDIT: After checking Android file host I found a link to the latest G920t1 firmware. Downloading now in hopes this gets me one step closer. https://www.androidfilehost.com/?fid=24591000424951428

Well I got the Metro PCS software running fine and when following this guide on unlockbase it says I just need this TMobile/MetroPCS unlock code and to put in the new SIM card and it should work.

Will report back later this week after purchasing the unlock code and attempting to input it.

One other note is when booting to stock recovery it warms me of multi csc. Its my understanding that this interferes with OTA updates. Is there anyway to fix the multi csc so my friend can take the metro pcs OTA updates or will I have to manually update them for him each time a new one comes out?

Your best bet is leaving it on tmobile rom.. if it's unlocked it's unlocked the sim will work just fine... just because you're using a different sim doesn't mean you gotta change roms
Leave it on what the device actually is, and let the unlock code make anything work for you
The S6 development is pretty dead and you will only really find updates for ours first, and if it's an original Tmobile device.. keep it on that, it's unlocked to work with anything but you don't have to flash anything specific to it G920T Use tmobile stock rom, unlock it and move on and do your business.. install twrp, get root , maybe a custom kernel and or rom?
If you root and leave stock recovery you're gonna have deep sleep issues, there hasn't been any MAJOR updates in awhile and it's only gonna go slower and slower with our device getting replaced by S7's and Note 7's
Roms will be updated to newer firmware bases, and JUST the bootloader and modem files will be online to quick flash within 2 minutes in odin to be updated then flash a updated rom base to the newer firmware if any future releases come.
Don't know too much about CSC sorry about that, but hopefully I at least get you on the right track?

The phone is locked. TMobile has the SIM unlock from the dialer disabled on the s6 firmware. You have to go through them to get it unlocked which my friend is currently unable to do, due to issues with payment on his account. I checked his imei and it says it's all good so I assume a traditional SIM unlock using the Metro pcs software should work.
I wasn't going to root or install twrp as this friend has no need for either and is fine staying on the stock software.

Getting second SIM working again

Hi all,
I only recently got a new Moto G5s Plus from India (XT1804).
And the first thing I did was unlock the bootloader and root it, unfortunately the second thing I did was try to use Android Pay, at which time I found out that it's not supported with an unlocked bootloader.
In reverting the stock rom (as https://forum.xda-developers.com/showpost.php?p=73795447&postcount=37) it has obviously upset the dual SIM operation, and now I'm down to just SIM 1.
Is the XT1804 stock image available? Or any other ideas for getting the second SIM working again?
Regards,
Bevan

The only mess up happened when u ysed the commands erase modemst1 and erase modemst2.
Had same issue with oneplus2. Had tp get my motherboard replaces as I dint had the EFS backup using recovery.
I think that you will have to-
1. re install twrp and restore your efs if you have a backup,
2. if (1) dosent work, try flashing the available NON_HLOS.bin . {Practically itwould do little help}.
3. wait untill moto releases a firmware with updated modem ( NON-HLOS.bin ) file as it usually has the data stored in modemst1 and
modemst2
4. Relock bootloader and go to the service center. dont mention that u unlocked the bootloader . if they ask, simply deny.
PS -
1. Android Pay isnt yet available in INDIA
2. I hope that when you dial *#06#, u see IMEI1=some value and IMEI2=0

Thanks,
Yeah I guess I'll have to wait for the Oreo update later in the year.
I'm in Australia, which is why Android Pay works.
On doing the *#06# I do actually get two IMEI numbers reported, and I have actually had the second SIM work just recently, so maybe things aren't all so bad.
But it almost seems like it's not using all the bands available in AU (which pretty much matches the bands used in India, although AU has LTE B42 also).
I guess this is part of the modem flash.
So I'd just need the modem stuff from an Indian phone?
I guess I'll check what bands are reported and go from there.
Thanks again.

Dear @bevanweiss,
As both of your IMEI's are intact, I don't believe that its any problem with your phone. your phone is totally fine
I highly recommend you to try switching your sim 1 (putting sim1 as sim2 and sim 2 as sim1)
Moto G has 4G support on both slots however, only 1 slot at a time can stay on 4g.
I say this, because in India , we have a service provider (Reliance Jio) who only provides 4G and no 2g or 3 g bands.
When I first booted up my phne with jio sim in slot 1 and vodafone india sim in slot 2, the voda sim got registered 1st and even though jio sim was in slot 1, it did not have any network. Even if i change prefered network type of sim 2 to 2g or 3g, there was no choice (option) to select 4g on sim 1 as 4g option was still visible in sim 2 settings.
Solution that i used,-
1.removed both sims and inserted just jio sim in slot 1 and rebooted.
2.set it (Jio sim 1) as 4g,
3.pulled out the tray and added voda to sim2
I will be really glad if any of these details help you.
I recommend you to backup your EFS partition asap.

Does regional activation need to be performed (again) after flashing?

I'm in the U.S. and am interested in the Exynos Note 9 N960F offered by Clove Technology in the UK (I want the Exynos variant so that the bootloader will be unlocked and I can eventually flash custom recovery/ROMs). On Clove's site, they mention that:
Code:
Since September 2013, Samsung has implemented a 'region lock' on all new stock...
for correct operation, this handset should be activated inside one of these countries with a SIM card issued for use there.
The device will then be able to accept SIM cards from outside of these countries. Activation requires turning the device on
for the first time & completing set-up with the SIM installed, then completing at least 5 minutes of voice call(s) with this SIM...
If this activation procedure is not followed then the device will lock when first attempted to be used with a SIM card from outside of these regions...
I'm fine with the activation procedure, but I'm not certain that it would persist through a flash, especially if I wanted to flash back to stock -- does anyone have experience with this matter? Would a regional activation need to be performed again after flashing recovery and/or ROM?

once its unlocked its unlocked for good. people have been ordering international phones from them and other retailers for years and they all get the 5 min call to unlock and device is shipped.
users have wiped countless times and flashed back stock or custom system just as much.
since the network unlocked it with that 1st 5 min call on original soil, it won't relock it back.
forums would be full of: "my region lock relocked"
so all in all dont worry just specify to them that you concent for them to break the seal and use the phone to make 1 call.

Unlocking my Note 8 by flashing Hades ROM or Reflashing Openline Firmware

My note 8 is locked to csc GLB and I can't use any other sim, is it possible to unlocked my Note 8 by flashing Hades ROM or Reflashing Openline Firmware? Thanks <3

Call Globe, it's not illegal. You may have to go in person to one of their stores.
Eventually someone will provide you with instructions on how to reboot your phone, input a code, adn your phone becomes openline.
I've got a smart sim now and I'm free to use it on either sim slot with data enabled.
