[Q] [Solved] Unable to unlock Note II (SGH-i317m)

Hello XDA and Happy New Year!
I have a rooted Note II sgh-i317m locked to Bell Mobility. I would like to use it with another carrier. I have asked one source for an unlock code, and verified that he received the correct IMEI for the phone, but he said he was unable to get one. I have tried "00000000" but that doesn't work.
I rooted it to try GalaxSim Unlock from the Play store. GalaxSim says it is incompatible with this device. When I click "show details" I get "undefined" for IMEI, Sim Lock status, Product code, Serial Number, and all the rest of the fields. (I believe the app is using the android SDK to query the device for these settings and getting nulls.)
Rooting was a piece of cake with Odin, but how do I unlock my phone?

rogers sgh-i317m
HELP! I have a note 2 from rogers, i recently tried to do the service mode unlock. (#*197328640#) followed the instructions but i was missing the option 4 nv data. found out later that it was 4.1.1 i had 4.1.2. So got impatient took it to the local cell unlocker fella. He ran into trouble with entering the unlock code then attempted a process that reversed what i did and entered the code, this seemed to work the unlock with the code was successful. Or so it seemed until i inserted my telus sim card then my $780 dollar phone that i just paid cash 2 days ago wont accept the sim or any other including rogers. I tried rooting and i put 4.1.1 back on this got me to the point where it will accept a rogers sim but data will only run edge and call out if i set it to gsm only in network settings this is the only way it will accept a rogers sim only

unlocked
me too , i can not unlock my note 2 canada sgh-í7m

No.

i know it a little late but if there are still people reading this today, well... this worked for me, and you need to be on 4.1.x variant of the note 2 i317/m rom.
I was initially on a 4.4.2 Koodo variant and downgraded it to a 4.1.1 Bell variant before i was able to successfully unlock the phone, since anything after 4.1.x that method is blocked/unavailable/patched. After i was done, my Videotron sim card was accepted and LTE is working flawlessly. Flashing Bells 4.4.2 rom posed no issues and phone was back to normal. Software updates were being checked normally (even tho no official lollipop will ever come from Samsung... but just saying) and nothing was acting out of the ordinary.
only problem is (but shouldn't really be anymore) that your KNOX counter will trip and will stay stuck at 1 due to some hardware thingy being physically changed. This is because of the Security enhancements being violated when downgrading from 4.4.x to 4.1.x. (kitkat to jellybean is a big nono to the SE, but the other way around or kitkat to kitkat is fine)
if any issues or questing feel free to ask GL

[Q] LG G2 Root/Unlock Issue

Hi Guys,
Yesterday i bought an LG G2 Sprint version. The guy who sold me told me it was unlocked and i used a prepaid sim to confirm it and it worked perfectly. But then he reset it and now the prepaid sim doesn't work. The phone is rooted and now the software version is CloudyG3 2.0
The phone model number is shown as LG-D802 even though its a sprint LS980. I have no idea what to do, how to unlock it or how to unroot it. Your advice is greatly appreciated.
Regards
Sunera

put in your sim card., restart the phone and dial *#*#4636*#*# select phone information and set the preferred network type to gsm auto prl ho back to yout home screen and your phone should read your simcard.

[Q] Pls Help! Need to determine unlock status asap. Also, USSD codes failing

Hi.
I am unsure if my phone is unlocked and can proceed with porting my number over to Metro PCS. Please help me with advice how to proceed. I decided to move my service to Metro PCS since they are now a Tmobile company and after lots of research, I found that I can use my current phone/software as long as it was unlocked. I recently purchased my Galaxy s4 second hand and assumed it was not unlocked. I had immediately rooted it and flashed a new rom (Insane Kitkat 4.4.4). The phone has been working well. I already have requested and have my unlock code from Tmobile.
When I went to the Metro PCS store to port over my number, the phone did not request an unlock code when inserting their Metro PCS sim card (not activated). They said that my phone may already be unlocked or that it may not need to be unlocked since Metro is now owned by T-mobile. They stated that it may work if they go through the entire registration process, port over my number and activate it but that it would be a gamble. If it did not work, then I would not be able to go back and reactivate my sim immediately with Tmobile since it would then be in deactivated status with them.
I tried to find out if it is already unlocked by *#7465625# but my phone will not run this or any other USSD codes to verify. I keep getting errors when trying any USSD codes. A message says 'USSD code running' then "unable to process request".
A friend of mine has an activated Galaxy S4 on Metro PCS and I tried inserting her sim card to prompt for the unlock code but my GS4 just booted normally then showed 'not registered on network'. It did, however, have cellular signal bars. When I inserted my Tmobile sim into her GS4 it did ask for the unlock code normally.
I am at a loss now..

funny, I like to know if there is a way to check carrier unlock status for simcard without having to put a simcard in.

T-Mobile phones work with metropcs without the need to unlock

Could the custom rom be suspect?
Maybe need a stock rom to get carriers sorted out, then go to custom roms.

I ended up contacting Tmobile and they stated that the phone showed unlocked status already but I think you are correct. I wasn't aware they could tell me this. It was very fast and super easy to find out.
I have the phone working great on Metro PCS now. USSD codes still failing though...

Use Verizon note 4 on AT&T

I got Verizon Note 4.
Verified that it is unlocked. Not stolen. No contract binded from Verizon store and through phone (Clean phone)
Android Version : 5.0.1
Location: Las Vegas
Insert AT&T sim card. No signal.
Change APN setting following the information on AT&T website. Still not working. No signal.
At&t store rep. said I need to l unlock the phone ( I already check with Verizon via phone and store)
Verizon rep. on phone said: I should be able to use the phone with At&t sim card
Verizon Rep. in store said : Galaxy note 4 won't work on AT&T. It needs to be rooted by an expert. Only Galaxy S5 or later version will work.
I searched websites and many say that they are using Verizon Note 4 on AT&T network (At&t sim card)
I just need to use phone and text message. No data needed.
Anybody can help me?

I was able to use SIM from AT&T before yesterday, but after trying to update the firmware using Software Upgrade Assistant tool on Windows 10, it's now stuck at 'searching for service'.

Did you change the network settings from global to lte/GSM?

I am reading this. Maybe a solution.

Did you try to insert a different carrier sim card and entering the unlock code?

After reading post i see you have a att sim sim on verizon phone. This could be a problem as verizon and att dont play nice. Stupid question is did you actually pay for service?

Yeah. Me either.

Did you do a factory reset after software update. Usually helps. Also mess with APN settings. Reboot after changing APN.

Problem solved.
Changing APN settings and reboot did not work. I just inserted the Verizon SIM came with the phone and made a phone call. Of course it's not activated, so I hang up when it reached Verizon automated system. Guess what, now SIM from Lycomobile works. H2O Wireless SIM also works. It means that it now can work with AT&T and T-Mobile network.

I'm in a similar boat as you (4.4.4 on Cricket Wireless, wanting to upgrade to 5.1.1). I just want to make sure I understand what you did to restore service:
1. You had phone working on AT&T with an older Android version (KK?)
2. You upgraded to a newer version via the Verizon upgrade tool (I assume 5.0.1 since 5.1.1 is not yet available via the tool)
3. You lost AT&T service after upgrade
4. You were able to restore AT&T service by using an inactive Verizon SIM and making a phone call
Is this correct? TIA

Mostly, except that I tried to upgrade from 5.0.1 to 5.1.1, but found that 5.1.1 was not yet available via the tool, but the process of installing the software on windows 10 and maybe I also used the Verizon SIM during the process which might have messed something up. I updated the firmware to 5.1.1 by downloading the zip file in a thread here and flashed it through recovery. The network connection problem was then solved by making a phone call with the SIM came with the phone.

I just updated via the Verizon tool (BPA1 finally showed up) and it was, surprisingly, perfectly fine. I first backed up as much as I can (via Smart Switch and Helium app), then pulled my mSD card, left my SIM card in the phone, and proceeded to update. After the first boot stuff (app optimization, etc.) I soon saw the AT&T sign in the notification bar, and I was able to make a phone call without doing anything else. With all the reports of SIM card locking after updating I was worried that I might run into the same issue, but was pleasantly surprised that I didn't. I had to re-enter the APN setting as the upgrade seemed to have removed it, but after re-adding Cricket's APN I was able to get cellular data as well.
Thanks again for your help

You need to access the hidden menu and change your radio and modem protocols. There's a forum on XDA called domestic and internation sim or network unlock for spring but should work the same on verizon

fyi, i got my note 4 working on gsm using 2 different freedompop sims-the at&t lte sim gets lte via band 4.
the global sim based on t-mobile did get hpsda+
just change the apn

no network available. only getting AWAYs

as the title suggests, i gotten the lg g3 from a guy off kijiji. He was with virgin mobile its d852. i payed to unlock the network and put my WIND sim in. I unlocked the network when there was no sim card. I put my sim card in but the only available networks i was getting is all away.
i swapped the sim thinking it might be that. no luck. i checked to see if this was blacklisted, it wasnt.
im running on cm13.
could this be because the bands are not activated? IF so, i tried following this guide http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 but it didnt work. i couldnt get the right driver to show up.
Also could it have been impacted by unlocking the network without the sim card in yet?
if someone can help with skype to speed things up for live debugging that would be greatly appreciated. you can add me at [email protected] for skype.

update: so i called wind to see if they can register the phone as on the network and they said they cant put the imei on the account. what does that mean?

Wind needs d852g... Not d852... There is some old threads of people converting the rom and modem to d852g which unlocks the band required for wind.... Search for that, no idea if it works or not tho
Sent from my LG-D852

i had a g3 before and it was d852 and it worked fine...
like i said its d852. i couldnt even flash d852g in.

swapped sim cards with a friend who is also on wind and my g3 couldnt get service but my sim card worked fine on her phone.

another update flashed 852g firmware on my 852 no change. i did so with 852g firmware and 852 dll.
i also flashed 852 tot with 852g dll and still no change in network.
called virgin mobile and they see that the imei is no longer on the account.
this is such a pain does anyone have anything to help??? is there an easy way to view all the bands the phone currently have??

anyone??
