I use a samsung captivate that was locked to Rogers. And now I am running it on Fido
I have been having issues connecting to 3G for over 6 months now. I completely gave up on the idea and lived off 2G, until someone suggested that I had unlocked my improperly. I believe this to be the root of my problems. I need to figure out how to lock my phone, and then if I can unlock it it properly, all my problems will be solved. PLEASE HELP. I will now try and explain all the different methods that I have used
The method I used initially was by extracting nv_data.bin file and using a hex editor to edit it to unlock. This did work, and my phone was working perfectly. But on a ROM update my 3G connectivity issues started.
I have to explicitly state 'only 2G' on my network connections, otherwise I lose my voice connection as well (because somehow the voice connections runs over the data connection - and one wont work with the other)
I decided to unlock properly - by buying a code off ebay. The code is based on the IMEI number of the phone.
I tried locking the phone by entering *7465625*638*# and entered
302720 (mnc/mcc for rogers)
and my purchased nck code
the phone even states that the lock code was successful. But on inserting my fido SIM, my phone acts like it did before - i.e. voice connection does work unless I explicitly select '2G only'
Initially I also tried locking by reediting nv_data.bin file using a hex editor. The instructions state editing the address '0x181468' on the file. There are 5 different bytes representing different locks (network lock, subset lock, sp lock, cp lock, data lock) and they are represented in binary. On just changing 'network lock' to 01 to phone acts the same. But on changing all the values on all the bytes the phone locks and asks for an unlock code on restart - but the purchased nck code does not work
This is over 6 months of trial and error, so I apologize if I am all over the place. Please provide any suggestions and I will clarify as soon as I can

Hi I've got a UK T-Mobile SDAII on contract, unlocked thanks to this forum, which I sometimes use with a French SFR pay-as-you-go card.
Somehow I've blocked the PIN on this card and have had to obtain a 7 digit PUK / Personal Unblocking Code. I can key in the code, but when I try to press the 'done' key, nothing happens.
I've also tried unblocking it via my 'Super GSM Reader' which does process the PUK, but says that the code is incorrect - although in the absence of proper instructions for the software that could be because I've not used it correctly (or because the PUK will only work in the phone?)
Any ideas how to get around this? Also, why is the PUK linked to the brand of the phone - and is this why the GSM reader didn't work?
Thanks...
I'm having some issues with my "unlocked focus".
Such as root menu code in diag menu doesn't work
phone isn't always connected (seems like i have to force it to try to connect to network, ex. enter URL or bing search and says isn't connected to network, try a second/third time and it usually works)
I was wondering if maybe i didn't get the "master unlock code" for my phone?
are there multiple unlock codes, is there anyway to confirm focus is fully unlocked?

I was just on the focus forum and sadly it looks like there is no way to unlock the phone from AT&T. No one has managed so far.
Had purchased an ZTE Flip phone for $39 at AT&T San Francisco year back and used for couple of months. Now it is in India and I would like to use this for my father. However it requires unlock PIN
I tried raising request with AT&T support no help so far even though I provided my purchase receipt. Can someone help me ??
Regards

Baseband/modem I747UCUFNJ2, stock 4.4.2 rooted. Phone from AT&T working ok with Claro Brazil (code unlocked) . After upgrading, lost IMEI. Flashed new modem and IMEI and IMEISV ok now. Checked IMEI number, is the same printed behind battery on phone. But now can not make calls. Got message 'No SIM card'. Ordered a Sim card tray, replaced it, but got same message. Phone has strong carrier signal. After reading a lot, I ordered a paid unlock code, but seller stated that code doesnt work in android 4.2.2. Even though, I tried to insert it once. (#@7465625*638*# - have to use it since phone doesnt ask for code at starting). As stated by seller, got message 'unlocked unsucessfull'. So now, what can I do to unlock the fone ? I have access to a hiden menu by dialing *#197328640# , but dont know how to use it. I have read a lot during this week. Did no find any helpfull information. Any help will be apreciated. Sorry for my bad english.
Sounds like the baseband and bootloader and too new for the ROM. You probably need to upgrade from stock 4.2.2 to stock 4.4.2 or flash a custom ROM based on a TW-kernel.
I edited/corrected my wrong information. The phone is on 4.4.2 stock already.
Try this:
Method 1:
Go to the dial screen and press #7465625*638*#
Once prompted for code, enter 8 digit Unlock Code.
Method 2:
Turn off your Samsung phone
Insert a non-accepted sim card (different from the original carrier) and turn your phone back on.
When prompted for the unlock code type the UNFREEZE code provided. If you are not prompted, go to your dial screen and type the UNFREEZE code, now press enter, send or call. You will receive an unsuccesfull message, don't worry.
Once the phone freeze is disabled, the Network lock or SP Lock screen will appear
For Network lock enter the UNLOCK code provided. For SP Lock enter the SERVICE PROVIDER code
Your phone is now fully unlocked!
If you get "unsuccessful" again then hit Dismiss button and type *2767*3855# on phone keypad and try this procedure again (CAUTION! This will reformat all your data!).
Method 3:
You can try this method without the sim card or with the original sim card
Type #7465625*638*CODE# (CODE is the Unlock Code)
Phone deactivated message means its unlocked
Dear all,
I'm having some serious issues about connecting to my service provider via my Nexus 5x (model LGH791). I'm based in Germany, trying to use o2. Due to the fact I'm using a german user interface some of the following translated description may vary from the original english descriptions.
Bootloader Info:
PRODUCT_NAME - bullhead
VARIANT - bullhead LGH791 16GB
HW Version - rev_1.0
BOOTLOADER VERSION - BHZ10r
BASEBAND VERSION - M8994F-2.6.32.1.13
CARRIER INFO - N/A
SERIAL NUMBER - 00b5xxxsecretxxxx
SIGNING - production
SECURE BOOT - enabled
DEVICE STATE - unlocked
Recovery: TWRP 3.0.2-1
Kernel: Stock Kernel.
Root: No, not rooted.
EDIT:
IMEI: looks like a valid IMEI
When I try to unlock my SIM via PIN I read the message: "SIM PIN Operation failed".
When I'm searching manually for a provider under Settings > Mobile Network I get the message "Error while searching for network".
I already flashed the sugested image from this XDA post here to change the base band.
I flashed the PureNexus ROM located on the XDA-Developers Forum, to change the base band too.
I removed the partition modemst1, suggested by this post, too.
I re-flashed the latest Stock ROM MTC20F from Google Developers.
I were able to choose the "European" and "Automatic" option under *#*#4636#*#* but I had to choose an option multiple times to successfully set it. Even choosing the USA Band says "Setting [USA Band] Unsuccessful". After alternating between "EURO Band" and "Automatic" a few times (varying) it says "Setting [EURO Band] Successful". Seems like some settings can't be set right away. Confusing.
When I'm prompted to unlock my SIM via PIN, I'm able to unlock it the first time. A few seconds pass and I'm prompted a second time resulting in a waiting/looping screen that says "Unlocking SIM..." that seems to be canceled after a timeout. The SIM card won't get unlocked after the second prompt.
Right now I'm not able to get any connection to a mobile service. The rest of the device works as expected.
I tested my SIM card in my Nexus 5. It's working fine. It's a self-cutted SIM card, formerly in the format of a microSIM.
I tested another SIM Card, used within an older HTC One Mini, that is working fine, too. It's a nanoSIM.
Anyone got any idea what's going on?
Best,
huppys
