[Q] Official Tmobile JIC6 Update loses unlock

Ok.. sooo.. Some people have gotten the JIC ota update from tmobile USA.. Well i decided to go ahead and update it. Well I lost the carrier unlock on it now.
I was just the stock rom on it rooted and unlocked using the one click unlock to get teh codes to unlock the phone. It worked then. Now with the JIC6 update i have lost that unlock. Also the one click unlock app to get the codes no longer works. I have also seen other post about using a hex editor to look at the nv_data.bin file to look for the unlock codes (no success). I have the original code from before the update, but it does not work. Is there a Way to unlock the vibrant with the JI6 update?

Just enter the same code you got last time. and it will unlock you.
If anyone else reads this. Please keep your code. and put it someplace safe. everytime you flash you will need to re-unlock most like a iphone.

Interseting that i didnt even have to reenter it. First when i updated and than checked teh network lock code showing that it was on so i than proceded to use the one click unlock app and it didnt not work. SO lucky for me i have a screenshot of the code when i first used the unlock app. so i did the same process and put in another carrier sim and entered the unlock code. It told me it was unsuccessful. Now that i went to try it again after my first post. I procceded to put in the other carrier sim card and it was unlocked.
Oh well. Thanks!

He says in the OP that he has the original code, but it doesn't work.
I know this is actually a known Samsung problem that has happened on many of their phones (even ones that came unlocked from what I've read) & generally re-entering the key works.
If it doesn't work for me, I'll call up TMO & complain. I bought the phone at retail price off contract, so they should give the code w/o a problem.
Generally as long as you've been a customer with them for at least 30-90 days (and your phone is beyond the returnable period), they'll give the unlock code if you call & ask for it. Sometimes you have to say that you'll be travelling out of country in order to get them to give it to you.

Is there a way to unlock without putting in a foreign SIM?

WTF !
Do you mean that updating the device to JI6 will lock the phone ?!
I unlocked mine with a code is that means I'll lose the unlock ?!

I discovered this a few weeks ago. I was working on a fix when I bricked my phone.
I just got my replacement on Tuesday and will be continuing the fix.
What happens is either something within the ODIN process, or on the rom itself puts a generic bml3 block on that contains all F's where the unlock code is stored.
I also know that it's stored on the nv_data.bin in the ./efs block.
I have been able to get my unlock code to be seen by the sgux program when modifying the bml3 file and pushing it back to my phone.
I will be working on nv_data next, though, seeing as my new phone has the unlock codes already, I'll have to do some editing and backing up.

I have my old codes with me so can someone confirm if old codes still works after the update ?

Thanks for sharing the information with us regarding phone. It may help us n the future.

Yeah after my original posts i think your old code will work. It will probably give an error of that it was unsuccessful. Just ignore it. and and just reboot the phone.
so basically to recap what i did.
updated JIC6 ota with tmobile.
checked network lock *#7465625# ( showing that the network lock was on.)
tried that software one click app to get code. (unsuccessful)
powered off phone
put in another carrier sim card.
bootup phone.
put in old code i had from before update to jic6 ( says that it was unsuccessful )
power off phone
put back Tmobile sim
power off phone
put other carrier sim in
unlocked!

i dont have tmobile sim ...do you think it needs that ?

I ran into this on my old vibrant running jfd. Unlocked and rooted and I needed to reflash jfd with odin. Phone relocked itself even reflashing same firmware. Efs data didn't change because the unlock code could still be retrieved. But when I inserted my att sim the code unlock said unsuccessful no matter what I tried. It never unlocked again.

So old codes didnt work for you and you are stuck.
can anyone confirm if we should update or not to remain unlocked ?

anyone confirming this ?
I got two different statements here

Ok, I updated my vibrant to JI6 today and it didn't lock my device !!
Since I don't use T-mobile data plan so I downloaded the leaked rom from (Vibrant Android development) section then I flashed the stock rom followed by JI6 ROM and it's working perfect !!
Maybe because mine is unlocked officially by T-Mobile code !

Or may be only ota is locking
We need more info

Updated mine through odin.. still unlocked.

thanks...i just updated with odin and mine is unlocked
Now time to check whats new :d

They will not release a code nor will att for 9 months after the phone is out. You may call and ask.
Thats why i offer unlock services for these phones.

Successful OTA update yesterday, NO NETWORK LOCK, phone was rooted with no lag fix

[Q] HD2 gets data but can't make or receive calls or sms

Hi guys,HTC tell me my beloved HD2 is now a brick, however it receives data even though it won't handle calls - so is the radio dead as HTC techies reckon?
If I try & make a call all I get are three 'dub dub dub's then nothing
The problem started after I had my number ported from Vodafone to T-mobile (UK) Trouble is I also flashed an Android ROM (Nexus fro XDA) at the same time so not sure which caused the problem.
Phone has always been unlocked
Checked APNs & so on, factory resets etc.
Tried different (Tesco) SIM same issue
Tried T Mob SIM in different phone OK
T-Mobile techies tell me IMEI is not blocked but can't come up with a solution
Flashed back to stock WM6.5 ROM from HTC site via SD card (previously tried USB) which I believe updates the radio as well? Bootloader tells me I'm on SPL 3.03 so everything should be back to factory settings Radio is 2.15 50.40
Could it be that Vodafone have somehow locked my phone in the porting?
What else can I do, please?

Ok you said your device is unlocked, do you mean SIM unlocked? Cause if it is not SIM unlocked this would be the reason for your issue.If it is SIM unlocked then either you have a faulty SIM card reader in your device, your SIM card is faulty, or the carrier has not done something right. Last thing I can come up with is that something could possibly be wrong with the internal antenna of your device. I will contemplate more on this and if I come up with something I will post back here in this thread.

Hi thanks, its SIM unlocked. Previous to changing carrier/flashing ROM (wish I'd done one at a time!) everything was fine SIM read OK, antenna must be OK as I can connect to internet.
Any further ideas appreciated, however!

Could be a bad unlock occurred but it is unusual.
reflashing rom maybe a good test option as will trying a few other sim cards/providers to rule out sim & network issues ...

Also when you did the SIM unlock were you using Windows Mobile or Android. You have to use Windows Mobile to SIM unlock the HD2 or it will not work.

This is not entirely true: there are android NAND ROMs that allow you to entry SIM-unlock code!
Edit: it seems it unlocks it temporarily until next reboot! I'll study that and post observations...

Yes it is entirely true, the SIM unlock is something the is done through the IPL. This means the OS has to be able to communicate with the IPL. When you are using Android neither cLK or MAGLDR can communicate with the IPL. The Android ROMs do have the SIM unlock feature but it will not work on the HD2, well it works bit it does not permanent and you have to do the unlock every time you reboot the device. This has been proven time and time again here. Take a few minutes to do some searching on this subject and you will see I am telling the truth. Better yet ask Samsamuel or MisterB andthey will tell you the same.

Ok, thanks...
I'll do my homework!

He speaks sooth, this has always been an issue.

not getting calls etc
Thanks everyone for the hints, took it into Vodafone shop, tried a spare sim & lo & behold we have calls; so it was locked to Vfone, I just happened to be on the Vfone network when I got the phone
Now I have to wait for Vfone to get unlock code from HTC - 5 days! That's modern communications for you!
Thanks again

unable to recieve calls
Hi i recently flashed a pacman rom 4.2.1 on my hd2. All is working well except calls. Whenever i answer the call it freezes. I tried flashing diffrent roms but i still get the same problem. Please help!!

Not Registered on Network

Hi guys,
I recently picked up a used S4 on Craigslist for cheap because the guy "screwed up" using Odin and flashed something that caused his phone to not register on any networks. I figured, what the hell, it's cheap enough and I might be able to restore it. So far I've restored the Rogers firmware over Odin and tried installing a custom rom/recovery too. I'm still getting this problem unfortunately. The IMEI reported with *#06# and in the status screen does match the sticker on the inside of the phone.
So I'm sure everyone's going to suggest that the phone was stolen and the IMEI has been blacklisted. My provider (Fido/Rogers) apparently doesn't care if the IMEI is blacklisted, they'll let it run anyway. I called up Fido anyway (since I'm a Fido customer) and asked them about the IMEI of this phone and they say they don't have any record of anyone calling in reporting it stolen and they don't have an IMEI database so she didn't have much to say about it.
Does anyone have any other suggestions? I've also flashed just the kernel, and I will flash a modem onto it too. I know my SIM card works, and both my SIM card and the last owners SIM cards don't work. I know the radio works because it picks up the emergency signal fine, and the SIM tray isn't damaged because when I put in my Fido SIM the Fido APN's automatically come up, as well as the lock screen goes from "No SIM inserted" to "unregistered SIM." Could my EFS partition be borked? Wifi works and IMEI shows up correctly.
The buyer said he would take the phone back if I can't fix it, but I want to try a bit more before I give up. If anyone has any ideas or suggestions, that would be great. Thanks a lot in advance XDA!
Summary:
-Used S4
-Owner flashed something wrong in Odin
-Gets "Not registered to network" error, unregistered SIM error
-Tried restoring
-Tried new ROM/Recovery
-Carrier says IMEI is fine, also tried directly registering the IMEI to my account
-IMEI is correct in settings/sticker on back of phone
-Wifi/everything else all works

Sounds like it's SIM locked to a different network. Try the the guide here: http://forum.xda-developers.com/showthread.php?t=2285431

My girlfriend has a Bell sim, which when we insert, gives us the "Please enter unlock code" screen.
My sim does not do that. I know this device is for my carrier, but I figure the easiest way to get this going is to just unlock it and see if the problem persists on other networks.
I've tried that unlock tutorial before. The first time I tried it, when I just got the phone from the previous owner, it said "Golden-backup does not exist" so I couldn't do the restore step of that guide. After Odin-flashing everything and starting over, I can't even get into the UMTS menu anymore! I'll try another restore and give it another go though.
Edit: Another problem. I did a restore again using Odin and notices that it never properly wipes the phone. When I finish flashing, my Wifi still autoconnects on first boot, and every few seconds, a process crashes causing the phone to freeze. Has anyone heard of this kind of problem before?

Quick update:
Managed to Odin-flash it to the earliest firmware I could find for the phone without any crashing or freezing problems. Trying to do the network unlock method mentioned online. It does not work, even though I'm following the instructions to a T. Could it be that my EFS partition is borked and that the NV rebuild can't happen, meaning my radio configuration would also be borked?
Edit: Oh and when I booted up my phone for the first time, the phone was actually ON Fido! But within a few seconds, it went back to "Emergency calls only."

Hmm, that is some odd behavior, and definitely not a carrier lock. Shame it's never that simple to fix.
Not quite the same as your issue, but I lost my ability to make and receive calls after flashing a newer modem on an AOSP firmware. Flashing custom kernels, older modems, the latest stock rom and kernel were no help at all. I tried everything I could think of short of groveling. In the end the only way I got everything working again was to flash the original factory firmware my phone shipped with, factory wipe it from stock recovery, then flash it again. If you've already tried that (and I'm guessing you have), consider contacting Samsung regarding warranty. They've been really good to me in the past, even with second-hand phones.
I can confirm that Odin doesn't clean everything out. In my trials I also noticed that flashing via ODIN without a factory reset presented no setup wizard, caused lots of FC's and left some previous files hanging around.

Sounds like a bad sim tray.

I had trouble with my handset after it got run over in the street, making it's otterbox earn it's money. The only bad symptom after that episode was Emergency calls only kept recurring.
I cut a tiny square of transparent scotch tape, avoided touching the sticky side, and placed it squarely on the SIM chip's backside, to make it fit the sim slot more snugly. It sounds like you should try stacking two or three layers on your chip as it sounds to be more loose than mine is.

Hi everybody! Thanks for all the help trying to fix it! It ended up being that the guys the previous owner had unlock it used the debug-menu unlock method and my phone was one of the ones that doesn't accept it. Lots of other people complained about similar problems as me in the free unlock method thread. In the end, I paid for the FastGSM USB Unlock method and it fixed the problem.

OH MY GOSH YOU JUST SAVED ME from buying another phone!! THANKS so much.. I added 3 layers of tape on the back of my sim and it works!!! weird.. cause I have the Dual Sim.. and it was the first sim that would not work. the second sim was fine.. anyways.. THANKS SO MUCH!!

[Q] T-Mobile data with Sprint HTC 10

I purchased an unlocked Sprint HTC 10 intending to use it on T-Mobile. It seemed to be working okay, so I unlocked the bootloader via htcdev, flashed TWRP and installed SuperSU according to the instructions in the forum.
Doing all of that undid the SIM unlock, so I followed the instructions for the NV unlock from the HTC m9 thread. The phone seems to be unlocked now, as I can make calls, but I can no longer connect to data. I've entered the correct APN settings (same as I did before the bootloader unlock), but I get nothing.
Is there something I need to do to restore my T-Mobile data? Flash a radio or something?

could you get a solution for this. Have the same issue.

Sim card not recognizing

Got a tough one. Ever since last Wednesday my SIM card hasn't been recognizing like it should be. It will randomly stop working and not work again untill I flash a new rom/backup/stock. I've tried clearing the cache... Nothing. When I go into *#*#4636#*#*, if I turn of radio power, it will recognize my phone number after about 10 seconds. Also, It says that APN settings are not available for this user under APN settings... Any help is appreciated, thanks.

This only works with mediatek devices...

I have seen many posts about the sim card error, and have now experienced it myself. I have a USC XT1768 (on AT&T), running RR for about the last 4 months. Everything has worked perfectly until 3 nights ago when, suddenly, for no reason I had no service & saw there was "no sim" recognized. A Google search led me to switch to 3G and turn on airplane mode and reboot. After rebooting, I turned off airplane mode and service was restored. However, I am forced to use only 3G. After multiple "tests" switching back to 4G LTE, I always lose service. Yesterday, I "tested" again and LTE worked for about 8 hours before I got the sim card error. I re-did the airplane mode/3G process and I was back in business...just with 3G.
Last night when I got the "No Sim" error, I noticed that the preferred network in *#*#4636#*#* was "Unknown". It had been set to LTE/UMTS/Auto. It doesn't seem to make a difference if I switch it to Global, or anything else. The problem remains. Oddly, when I just entered *#*#4636#*#*, the preferred network setting was on WCDMA. Weird...I didn't select that setting.
Anyway, maybe this can kind of help someone else.

Tried the airplane mode/3g thing, still nothing for me. Just "lost" all recognition of a SIM. Nothing. No matter what I do, won't recognize. Lots online about it, loaded the latest F/W, etc., still nothing. The phone is like a new phone. Something feels hinkey about it though. Seems it's happening to unlocked Moto phones after about two-months.

I've had it for about a year when it happened, but what I did was send it to Moto and just told them it stopped working out of the blue. Flashed stock and sent it in. Within about 4 days they sent a new one. I would recommend that if you have a backup phone.

Did you have an unlocked bootloader (using the Moto code they send along with the warning that it'll void warranty)? If they still warrantied it, I'll do what you did, then sell the replacement ASAP. What an unreliable POS...

Not really. Clearly a small percentage of E4s have a SIM problem; Moto should own up to it. However, that's unlikely as they never acknowledged the HW GPS issue on the G4P line that impacts a much larger proportion of devices.

Yeah, it was unlocked but I don't know why they had still look it though..

If you erase modemst1 and 2, the SIM will be recognized again. At least, it was on my XT1768. I wrote a small TWRP flashable version, for when it happens when I'm out and about. Just boot to recovery and "install" it. It's attached to my reply.
Additionally, the following firmware build is supposed to have the fix for this issue: https://androidfilehost.com/?fid=746010030569967659
Addendum: AFAIK, all Moto E4's running a build less than NPQ26.69-64 have the SIM issue. From what I've seen, it happens when one doesn't have any signal for a few hours, then comes back into an area that has a signal.

Can you boot TWRP or another custom recovery? Need that to apply the 'fix' in the form presented. Not even sure it will work on a bootloader locked device.

Must be other variables involved. Have a much older build and frequently travel to/through areas with no coverage. Have yet to experience a SIM issue.

Your bootloader is locked, so you can't apply my fix from TWRP. You will need to hook up your phone to a computer, boot your phone to your bootloader (power + down), on your computer cd to your Android Sdk tools directory, then run "fastboot erase modemst1" and "fastboot erase modemst2", then reboot your phone.
However, you should be getting OTA updates. The most recent firmware should prevent the issue.
