[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] Help unlocking

For the life of me I cannot get this phone to unlock for a different sim
Ive tried the sgs unlock tool on both stock and a 2.2 froyo rom
I tried the windows tool posdted in another thread....the one with generatecode.bat ....it worked but it doesnt display a code on either the stock 2.1 update 1 rom or the foryo one....I dont know what to do
and yes im rooted

The windows tool worked for me from stock.
It doesn't generate a code though you input one.
Edit: link

Scroll down for instructions.

Did you try the sgs unlock PRO version?

I jsut bought the pro version and it doesnt want to work....it says it unlocked it when i use the unlock sim option and when i use the root or non root to show the code i get a unkown error

Call Tmo customer service. Tell them that you will be traveling overseas and you want to use a foreign SIM. Ask for the unlock code for your phone.
They will ask you for your phone's IMEI number.
Then in a few hours, or a day at the most they will send you the unlock code and instructions.

I dont understand why the paid app isnt working either....it just says no codes found unkown error and tmo wont give it to me....i hate them anyways

The app didn't work for me either. Did you try the solution I suggested above?
I use my phone in London the majority of the time having used that. It took me a few tries but it worked.
I agree with the earlier post that you can try asking tmo. They gave me the unlock code for my old blackberry after providing the IMEI.

I would get the error as well, but it did unlock. When you choose unlock phone, does it tell you to restart the phone with your SIM card?

System Updates Questions

I just purchased a unlocked my touch 3g ( I believe Magic) no slide.
At times my phone asks me to do a update.
When I look at what the update is it shows "Android System Update 1.2...The system is required to install Android version 2.2.1 on your device."
My phone states my firmware version is 1.6
So my questions are:
Do I need to perform this update?
Will this update lock my phone again ?
This is my 1st android phone and truthfully I'm not real technical. I have been going around googling different thing to make mysel more familar with the phone and Android.
Any help woul sure be appreciated.
Thanks in advance

Ok so 81 views and nobody knows.
Anybody have any idea what other sites out there may deal with this type of thing that they may be able to direct me to?
Thanks

Could you please provide the info on your fastboot? You can get to fastboot by turning the phone off, then turning it on while holding down the volume down button.

I hope this helps and what you were asking for
Thanks

First off, you do not need to update if you don't want to. Second, I think the update will relock the phone, so I recommend not updating at all, unless you have a reliable method of unlocking again.

I appreciate the info

Ok there are two things:
1) Sim Lock.. if your phone is sim unlocked it will remain sim unlocked.. actually I don't think there is any documented way to re-sim lock the phone.
2) Root.. if your phone is rooted i recommend installing a rooted version of the upgrade if you desire to upgrade.. otherwise the upgrade will either unroot the phone or fail because the phone is currently rooted (possibly causing it not to boot into android until you restore a good firmware)
Remember the sim lock is different from root.. and you can be rooted but sim-locked... or sim-unlocked but not rooted.. the simlock is just the tie in to the carrier and part of the Radio.. not part of the android firmware. Further its in a special radio settings region that is not flashed when you change the phone's radio.
So if you have the stock un-rooted/un-modified firmware and wish to update feel free.. just note you may want to back up what you can first.. some people have had problems with the update going slow until they factory reset after the update..

ezterry,
Thanks for the info.
Truthfully I'm unsure about many things on this phone.
I purchased this phone off Ebay as a unlocked only phone.
When I received the phone I just popped in my sim-set up the phone and was done.
At this point though I'm not even sure its unlocked because it is a T=Mobile phone and my service is myfamily mobile,which is just T-Mobile sold at Walmart.
I put in a sim card from my neighbors AT &T and it asked me for a pin #.
I skipped putting in a pin and the phone opened up but said no service. With that I am just assuming it is truly unlocked.
Am I correct?

Um.. if it asked for an unlock code its locked.. if it was sold unlocked and showing the code you ought to have been provided the code by the seller.
Pin usually just means the owner of the sim locked put a pin on the sim to prevent it from its data/service being accessed by others. (The sims owner ought to know the pin) This pin needs to be entered into any phone the sim is put in.

As soon as I find another person with a different sim card I am going to try it again.
I do think it was a pin # that was asked.
Unfortunately the owner did not provide any sort of code when I purchased.
Its my understanding,and I may be wrong,that you can purchase unlocked phones new,and if so I'm not sure weather or not codes are provided for new phones.
This is all very new to me so I am not sure.

If a HTC Dream/Sapphire was sim locked at the factory you must put in a sim card from another carrier and unlock the phone.. If it was never locked (such as the Google versions of the phones) this is not needed.
Once Sim Unlocked it will remain so regardless.

Yes, this is a My touch 3g google version phone

MT3G = T-Mobile = locked to T-Mobile US but running the Google firmware
ION = Google Development Phone = factory sim unlocked

So does this mean the phone is not unlocked and can only be used on T-Mobile?
or
Is it possible someone paid a 3rd party for a code to un-lock it?
I guess I really need to try like a AAT & T sim and see if I could service,as that was my undrstanding. I was under the impression that any gsm service provider uising a sim card would be operable.

You have gone in a circle now.. I told you if its sim locked when you put in a sim of a diffrent provider it will ask for an unlock code.. once sim unlocked it will *never* be locked again.
You will of course need a non tmo-us sim to be sure.
All I know is the MT3G will have been shipped from the factory locked.. I will not know the current state since the seller prob made sure it was unlocked if it wasn't already so if the phone was sold unlocked ..
The only other way I know to test is harder to do and possible risky with the firmware changes to do it w/o special htc serial wires.
And FYI a pin protected sim will ask for the sims pin before the sims carrier can be read (thus you need to provide the sims pin before it will ask for the unlock code if the phone is sim locked)

Ok,gotcha.
Sorry,told you not to savy
So I'll test another sim again and see what happens.
Thanks again for all the support

Ok.
So I pulled the sim card from my neighbors AT &T phone and when the phone booted up it asked me for :
"sim network unlock pin"
unlock
dismiss
My neighbor told me he didn't have a sim pin,but he used the code he has to lock his phone.
I received the same message when I tried someone elses sim who also states they have no pin number.
Message being: "Network Unlock Request Un succussful"
So am I correct in my thinking that this phone is not unlocked? and or it is sim locked?
I just e-mailed the seller asking him if he had the unlock code for the phone,so I can now only wait for his response. In the past he was not very responsive to past e-mails

Phone asking for simcard's PIN even though there is none inserted + MMI error

This is going to be embarrasing story.
I bought new Nexus 6p, and it required Nano Sim card. Being genious me, i've decided to cut my old card and insert it in the sim tray.
It did not work and asked me for sim card's PIN code (which i never set up). Figuring i must have simply broken the card, i decided to boot the phone without any card inside.
Now, when i start the phone, i get the same lockscreen right after Android Logo.
I have tried factory reset, and inserting brand new nano card from different carrier, but none of those it did work.
Using the emergency call dialler I tried entering PUK code *05PUKnewPIN*newPIN# and i recieve "Connection problem or invalid mmi code" error, with or without nano sim card.
Most of the fixes for MMI error are assuming that user can successfuly launch the phone as well.
I have yet to try putting "," or "+" somewhere in the USSD code, this is supposed to "ignore any error messages and perform the code" but i am slightly pessimistic about this.
I thought that maybe the pins were damaged, but they all seem to be allright.
I am a bit conflicted about flashing the image, since i am not sure if unlocking and locking bootloader for flashing will impact my warranty?
I have tried already flashing 6.0.1 stock on top of the stock 6.0.0 the phone came with, but I was still unsuccessful, since i did not enable USB Debugging on the phone and when performing flash-all command in ADB fails due to locked bootloader (that can be unlocked from the settings).
Tried fastboot flash unlock (since fastboot oem unlock did not work at all) as well but it did not work for me.
Based on this, those are the possibilites i consider:
*Try to get MMI error code fixed
*Flash the stock android once i get around locked bootloader
*check the SIM card slot for any dents on pins
*contact carrier and check if maybe it was somehow locked on their side
*Return the phone on warranty and hope that it will be accepted (i expect major hurdles along the way, since the phone was imported to Poland), this would imply that i should not interfere in hardware and software.
I feel that if i get one of mentioned above issues, rest of them should be a walk in the park.
I am really looking for feedback from you guys, since i seem to be unable to deal with on my own.
EDIT: Solved! Found an official google nexus helpline (support.google.com/store/answer/6301411?hl=en) from there someone contacted me and i was given directions on how to solve this issue. If someone finds this thread i needed to do another factory reset

samsung galaxy S4 unlocked asking for SIM network unlock pin

Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio

If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.

Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.
