FRUSTRATED! Unlock code suddenly appears.

Hi guys,
Today, after having my SGS I9000 for about three months, I ran into a very, very, frustrating problem.
All of a sudden, after I turned my phone off and on, it asked me for a SIM unlock code. I did not buy the phone from a provider. I bought it in Asia, independent from a carrier.
Why now? After a few months of working without any hitches, this happens.
After I dug around for some information, I tried rooting the phone so I could get an unlock code using an app. However, the three button method to get to the recovery mode doesn't seem to work with my phone.
This is truly a pain and I really don't know what to do. Can anybody give me some tips?

if the 3 button combo dont work, you will have to do the 3 button fix, you can do this by booting into download mode via ADB (android debug bridge) and then when you have fixed the 3 button combo, you can then root and install the app that removes the network lock.
I have no idea why that happened, normally when network lock is off it stays off.
Have you done anything to the phone that may of caused this ??
Anyway i know its quite a mission you have got to do, but when its done, try to make a nandroid backup for future references, or if the app gives you a code (i have never used it) keep a copy incase it happens again.

I don't think this has anything to with the network specific sim as u have said u bought it independent of carrier..Just contact ur network provider and they will give u the sim unlock code
After than go to settings and "Location and Security" and disable sim lock option
Hope it helps

Thanks for the replies, guys.
Yes, it is indeed strange that it suddenly popped up. It was working extremely fine before that and everything just went downhill!
I'm not sure if I did anything to the phone that may have caused it...I rarely download things and only use the phone to make calls/text/surf the web.
Doing all the necessary fixes seem to take quite a bit of time and from how busy I am these days, I won't be able to invest in doing it myself.
I am thinking of getting it unlocked professionally at a shop.
And I highly doubt it is an actual SIM code from my provider. I'm under Fido and I've tried most of the default codes and they do not work.

[Q] Name announcement instead of ring

Somehow my 9 year old daughter managed to get my phone to announce the callers names. its cool and all, but now i want to turn it off and cannot figure out where to go to do this. any ideas, or suggestions?
P.S. i looked it up, only place i can find anyone inquiring about this is on the epic 4G general and i looked and nothing there.

its in settings > voice input and output >text to speech settings > driving mode
uncheck it

it wasn't checked, so i checked it, restarted phone and unchecked it for ****s n giggles and it worked... thanks ciscogee!!

[Q] Mobile Data Will Not Stay Connected, Any Ideas?

Last night I went into Service Mode on my SGH-T889 and as soon as Service Mode opened, my 4G icon disappeared and then kept cutting on and off. I didn't even change any of the settings in Service Mode, I just left it as it was and rebooted. Now, after multiple restarts, re-entering the APN settings, and a hard reset, I'm still having this problem.
Has anyone else had a similar issue? Were you able to correct it, and if so, how? I have been searching all day but can't find a fix. I can still make and receive calls and texts, just can't stay connected steadily to use my internet connection. I am not rooted and I am using a Simple Mobile SIM card, running Android 4.3.

you more than likely change something unknowingly...
i did that once back in the day, with 'auto-answer mode'... Lol
didn't know why calls wouldn't come through for the longest time, then with enough playing around in service-mode, i found the option and changed it back. Lol
I'm unsure as to if there is a way to change all those settings back to default...
maybe the samsung flash tool would have something for this...
Personally, i would peek around in service mode, and try to deduct from the available options as to what might have changed, based on how comfortable you are with the options though, that might not be a good idea... google is a helper.
all else fails, if you can't use any warranty services for the device, they checking in the phone-specific forum and seeing if someone with the same/similar device can post their settings relative to the mobile network.
good luck

Multiple issues, I just tried updating. help?

So I've been using (T-Mobile) D80120a for a long time and was having some issues with it so I thought I'd try upgrading since latest version is D80120g. I was hoping it would fix some of them.
My issues:
1. If my phone was on vibrate, it sometimes would act like silent mode, not even vibrating when I would get a text.
2. Bluetooth (music) in my new car will sometimes pause, then fast forward to catch up. Not sure if this is my car or phone's issue.
3. Worst of all, my phone turns itself off without notice. Sometimes multiple times in a short amount of time. No sound, no vibration, nothing. Never while using it or charging but sometimes when I haven't even touched it...
4. Some apps randomly tell me my phone is not rooted when I know it is. I have and use SuperSU and I've removed some system apps such as widgets that I don't use and are safe to remove. Also, apps such as ES File Explorer refuse to mount the /system folder. I can browse and edit all root folders except that one.
After successfully upgrading to g, all issues are fixed except 2, which again may not be my phone's fault. BUT g has added a new issue, now knock on/off will not work for some reason. I've turned it off and back on, and restarted a thousand times. Is there an apk responsible for allowing knock to work? What all can I try?
and btw, I'm also looking for a bloatware list for t-mobile D80120g! All of them I have found don't include everything or has a bunch of stuff that isn't there. I know some of this is crap but I'm really trying to only remove safe stuff so my issues don't return!

Try this to see if the knock on/off works

The best solution is to open dialer menu and type:
5689#*980# (Sprint)
3845#*801# (T-Mobile)
3845#*803# (AT&T Canada)
3845#*802# (International)
3845#*800# (At&T)
3845#*980# (Verizon)
And when hidden menu is showed up, go to "Settings"
and go to "Update Touch Firmware". Then touch will stop working for 5 seconds after this it should be working.

I saw that post somewhere else but when I enter 3845#*801# I get the message "Connection problem or invalid MMI code"

There is no way this to happen. Be sure you enter this 3845#*801#. My mistake was swapping # with *. You are obviously on stock firmware. Be sure you have connection. When i was entering it i didn't have to press the call button. It automatically opens after you enter it right. If this not help i think you can try reseting it to factory settings.

Yeah I tried it many times and double/triple checked I'm doing it correctly. Nothing happens when I type it in and I get that message if I try to dial it. I am using my wifi but I also tried my phone's 4G, same result. Anything else I can try?

Ah I got it! You were right with the information you gave me, it fixed the issue. I am using a better dialer which apparently the hidden menu only works for the default dialer. Thank you!

How to get roaming to work?

I can't get roaming to work on my op6t.. can't find the toggle but also can't tap SIM1 without phone app FC.. any ideas and help would be appreciated..
Many thanks!

If you're rooted with Magisk modules, and most specifically one that does call recording I'm just going to tell you to go search from there. I got you halfway to your solution.
If you're not rooted, don't know what to tell you....factory reset.

Turns out something went wrong and the parts and toggles went missing in SIM settings after I transferred the data from my op6 to this op6t.. weird but solved now..
