[Q] Cannot unlock gt-n7100 for different carrier - Galaxy Note II Q&A, Help & Troubleshooting

Hi there,
I have purchased a Note II GT-N7100 in the philippines and it's locked to Smart mobile.
I have tried downgrading to version 4.1.1 firmware and attempting the *#197326840# code but that doesn't have the menu's as shown in other threads.
I have also tried the galaxy sim unlock app in playstore but that has a message of:
"Device updated to a new lock systemnot supported yet."
and a note on the webpage
"* Please note that due to different hardware, many LTE/4G devices aren’t supported yet. On some SGS3, SGS4 and Note2, a recent rom update brings a new lock system that can't be unlocked yet. Don't leave bad feedback, we’re working on it, but that’s a complex process that requires time and access to locked devices! *"
Does anyone know of any way to unlock these devices for different carriers as I want to switch to another provider...
Thanks in advance for any help

[Q] can anyone help with my htc touch pro 2

I need windows 6.5 for Canada Telus HTC Touch Pro 2. Have they released a version for Canada? If so, where could I find it?
I've been trying to upgrade my OS and when I attempt to download the update it gives me an error saying "this download is not suitable for this device" I believe it is because the download is for european phones.
In addition to this question, has anyone had any success unlocking the Touch Pro 2 from Telus to Rogers?
A quick response would be muchly appreciated.
Thank you!!!
ROMs are carrier specific, for the most part. If it isn't on the HTC website, only Telus would be releasing a new ROM. Most carriers have stopped development since the phone has been discontinued. Not likely you'll see a new OEM ROM if one hasn't come out already.
that sucks!! I don't understand why the rest of the world is compatible with this upgrade but canadian clients arn't? doesn't make much sense to me. but thank you for the reply

Complain to your carrier. The stock ROMs are locked to the carrier they are released to by design. If Telus doesn't have an update for it on their website, then there isn't one available. As far as unlocking it to use on another cellular network, you would have to obtain an unlock code from your carrier. This would SIM unlock your device, allowing you to use any GSM carrier with your phone.

I have rooted this phone, flashed TWRP Recovery and Flashed an unlock zip package which modified the baseband frequency of the phone with sprint. This modded unlock package is suppose to allow using the phone outside the USA...is for blacklisted phone of this post ONLY. But I haven't left the USA to test it yet. I return to Yucatan, Mexico in 5 days and will update this post...
If it works, contact me and I can direct you.
:good:
I hope to see if I can unlock. Any event notify them. Likewise if you manage to direct me how to do it please

Sim unlock galaxy s3

Anyway ? Possible now to unlock galaxy s3 t999 running 5.0.2 or 5.1 for that matter, I don't even know if buying an unlock code would even work at this point ?
First, you need to be on TouchWiz to unlock. Buying an unlock code has been hit or miss for some devices to take, even with official ones from T-Mobile

Noob asking for help updating from 4.4.4 to 5.1+

Hello!
I am a developer in New Zealand with a USA AT&T Samsung Note 4 sent to me by Oculus in 2014.
Sorry for being a noob with this stuff!
The phone has been unlocked to work on the New Zealand Vodafone network - for this reason (from what I understand) the AT&T Android updates do not work "Your device is up to date!".
A 360 VR video plugin I need to use requires Android 5.1+ but my phone is 4.4.4.
Is there a simple guide somewhere that I can follow to update my AT&T Note 4?
I do not care if it wipes any AT&T stuff - or are the different provider's versions of this phone actually different hardware-wise?
I've tried searching but lacking some of the terminology needed to get it done. It all seems needlessly complex just to update the OS...
I contacted Oculus support who forwarded me to Samsung support who told me to try "Smart Switch" PC software, which said my phone was up to date. Contacted them again and they told me to take the phone to a Samsung service center in Albany 30 minutes drive away. I'll try this if I have to.
Thanks!

Edit: My model number is SM-N910A

Thanks @norbarb.
Which files would I need though?
My AT&T Note 4 model number is SM-N910A.
Android version 4.4.4
Build number KTU84P.N910AUCU1BNK3.
I am not sure what the "S2EPK4 to S2EPK5" etc numbers are.

Flashing generic Samsung firmware to carrier branded Tab S4 (SM-T837T -> SM-T835)

I think this has been asked before in a different way in this section but no real response yet. I did some research in the other Samsung device forums and see that often it is possible to remove branding or switch carriers adjusting device ID and bootloader etc. But no idea how to do it for the Tab S4.
I'm sick of waiting for slow updates through T-Mobile (or any carrier) and would like to fully unlock it's potential with Android 10 rather sooner than later. I bought this device second hand network unlocked.
Any short or long answer to these questions? Can it be done? If so where to start?
Am looking to do so, with the t835 you will have full calling functionality,,,

not needing the calling function on a tablet. but steady updates are welcome... tired of waiting twice.. first for Samsung with slow update policies then another time for carriers that already got their money and cant care much a anymore...
i'd be looking for T835C since I'm in China now.

The short answer is no.
I've tried that after I found my T837V can be successfully loaded with T837R4/T837T/... firmware. I thought maybe I could flash stock firmware of other versions. But if you do that with any firmware other than T837*, you will get "secure check fail pit" error. So sadly no.

Thanks for the response! So it does mean you can freely flash T837 versions which could mean I can just wait for the first version that comes out with android 10. Any first release should work. Right?
Turkey version has it:

T837 is Turkey version and I've tried it. It can't be loaded, maybe it need to be T837x which are all US variants.
As for Android 10 update, I think this will work. I'm waiting for the first one who gives the OneUI 2.1 update. So far the Verizon version(T837V) seems to have the most active firmware updates.
In the USA, SM-T837 ARE carrier tablets.
There are the SM-T837A, V, and T; ATT, Verizon, T-Mobile. TheSe are locked to the Carrier. If you have them unlock it, OTA upgrades are over. If you know how to hack the firmware, you can write over the carrier version. The best way to go is probably custom ROM AND ROOTING. But in other nations, it will probably work to write a different Samsung ROM. The SM-T835 HAS no US version, so you can probably write any tab s4 Factory ROM to it.
The USA HAS so many cellular devices, the rules are strict. And, the carriers sell the devices pretty cheap. So, they want them to stay with their service.
T-mobile update for android 10 finally out just got it
