Invalid MMI code or connection problem - Galaxy S III Q&A, Help & Troubleshooting

Hi
I posted this problem in another thread, but most likely it wasn't the best place to do so. Hopefully posting it here, someone might have a better perspective and might have an answer...
I've read through the various posts in the forum, but I cannot seem to get a complete / definitve answer to my problem.
Phone: Galaxy S3
Original Firmware: Stock Vodafone Ireland (can't remember the exact version, but can trace it if required).
Phone originally was network locked, but unlocked with official key from Vodafone (no voodoo etc).
Description:
Downloaded Stock XXBLG8 from this forum.
Used a Win 7x32 with no Kies installed and with ODIN 3.04 flashed the phone.
No problems detected during flashing. When completed, did *#1234#
Found that phone had been updated correctly to AP:I9300XXBLG8.
Changed CSC to BTU.
Checked phone in download mode and firmware listed as "Official Samsung", no yellow triangle.
Checked in Kies and found that phone was upgradeable via Kies (got LH1 update via Kies).
Problem:
Since update, have a problem accessing MMI codes. The basic ones like *#06# or *#0000# and similar, work fine. Others (more complex) for example *#7465625#, do not work. Typing them produces an error "Connection error or invalid MMI code". I know these particular codes worked before flashing to XXBLG8.
Apart from this, the phone seems to be working perfectly well.
Is there a solution to this problem?
Any help gratefully accepted.

Having the same problem myself. I was Voodoo unlocked and got the unlock code from Vodafone IRE today but it won't work. Keep getting the same errors as you.
I was on stock XXBLG8 too, tried it with the original Vodafone firmware but still had problems. Would be interested if anyone had any more info about this.

They've probably been disabled by samsung. But they do work again on the latest JB leak.

Phone/ Text Problem after rom flash

I have already asked in the specific Q&A section for my phone but I thought i'd branch out to the community as this seems to be a general phone query.
THE PROBLEM
I have a problem with my phone where I can't receive or send text messages or phone calls however i still have signal and can use mobile data. The problem occured from a rom flash coming from Kalgecin's Unofficial CM10 builds to Chameleon 1.2.
ATTEMPTS AT SOLVING
I have contacted my provider's, T-Mobile UK, they have told me that everything is fine with my settings and have suggested I take the phone to a T-Mobile store.
I have used my sim in another phone and everything works.
I have used a friends sim in my phone and the same problem occurs
I have made sure the SMSC is that of my providers T-Mobile UK.
I have tried flashed a generic stock ICS 4.0.3 rom.
I have taken the phone back to T-Mobile 4.0.3 stock.
I have tried the following but the problem still persists.
Phone Version
PDA I9100BVLPD
PHONE I9100BVLPB
CSC I9100TMULPD
Hopefully someone can help. Cheers

[Q] Which stock image to use for dial a phone, UK

I have an S3 that I rooted a few ago, using CF-Auto-Root-m0-m0xx-gti9300.tar.md5 and Odin. The main reason was to use ClockWorkMod to backup an image of the phone.
Last week it started to play up. It regularly freezes and the WIFI will not connect. As I had it rooted, I tried the cyanogenmod 9.1 ROM. I still had issues with the WIFI on this, which led me to think that it was a hardware problem. I have gone back to my original backup (after rooting the phone), and it seems fairly stable as long as I keep the WIFI off.
I wanted to try reverting to the stock ROM, and if that doesn't help, I was hoping to try and get it sorted under warranty.
I was following the excellent guide on http://forum.xda-developers.com/showthread.php?t=1710613 but I cam a bit stuck on selecting the stock ROM to revert to.
I'm on the Orange network but I got the phone from dial-a-phone, so I didn't know if I should use the unbranded ROM or the Orange ROM. Orange has also merged with T-Mobile, so there is a third possibility, EE.
Using the keyboard shortcut, my phone reports:
AP: I9300XXEMC2
CP: I9300XXEMC2
CSC: I9300OXAEMC2
Do these refer to the original software or the firmware I flashed to get root permissions?
Any advice welcomed!
Thanks
It will be unbranded BTU.
Dial-a-phone is owned by phones 4 u. All these companies (CPW etc) supply unbranded handsets so they can be sold on all the networks they resell for. That way they're never left with a surplus of O2 phones etc, because they have 1 stock.
If you connect your phone to Kies it will tell you your version, unbranded BTU will be like the screen clip attached, if you don't have that download it from Sammobile and install via Odin

[Q] firmware update problem sg3 sgh-t999

I just bought a phone on ebay. unlocked samsung galaxy s3 sgh-t999. It's supposed to be brand new and was in the orig. box. But the build of the firmware is ZS and in kies it says
PDA:EMC
PHONE: LK3
CSC: EMC (CHN) <- CHN I presume is China
also my android is 4.1.1 and I would like it to be at least 4.1.2 preferably 4.3
but of course OTA doesn't work because of the country code. It says registering device then processing failed.
I've tried to flash using odin but I get aboot error with some roms and in some versions as well as sbl2 error with some roms and some versions.
and my phone in download mode says it's an I747 -- the at&t model. In gs3->settings->about device it says its a sgh-t999 which is what it should be.
Kies says the firmware is up to date. arg frustrating.
Everything about this phone works except for updating the firmware.
So I asked for a replacement...which I got today. Same stupid problem, not only that, but this one isn't recognizing my cut micro sim. So if it's between the 2 I would like the original one since it recognizes the sim.
I have read that I can change the country code, but I do not want to root the phone since I want it under warranty.
what should I do to update my phone?
Thank you for any and all help

[Q] Phone settings say g900f but odin says g900t

Hi Guys,
2 months ago I bought a Samsung s5 in Hong Kong.
While travelling through South East Asia this device worked fine.
While traveling through New Zealand (Old home) this phone worked fine.
While traveling through America (New Home) this phone worked fine for the first 2 weeks (on the metroPCS network).
The problem:
Randomly after 2 weeks the s5 stopped connecting to the metroPCS mobile network even though the network was available (btw metroPCS uses the T-Mobile network). It gives errors such as network not available or cannot register with network.
Things I have tried:
-Im sure the APN settings of the phone have not changed and I have double checked to see if they are correct.
-replacing the sim card with another does not fix the issue
-soft and hard reset of the phone does not fix the issue
-Getting metroPCS to refresh the service on this number does not fix the issue
Other important info:
-This phone was purchased in hong kong but it is from the Philippians according to Kies's firmware information (XTC is the country code)
-It is running a custom allianceROM that must have been installed by someone in hongkong
-The device is rooted (superuser app installed)
-the model number as shown in settings is g900f BUT when attempting to flash with odin the phone displays g900t and fails to flash the latest Philippians verison of kit-kat
I have 2 questions:
1. Any ideas why my network connection has suddenly self destructed (and how to fix)?
2. Would flashing a stock ROM to my s5 help? and if so why is there conflicting information on which model I own (g900t/g900f)?
Please help. I do have some know how on flashing android devices but i've really hit the wall on this one guys!
Cheers,
Yetti.:cyclops:
It's not uncommon for the model # to be different with a custom rom as that is a very easy thing to edit in the build.prop. It should tell you under the battery which one it is. As far as the network issues, check to see if the baseband and IMEI are still there and not listed as unknown or incorrectly. It's possible you could get away with flashing the appropriate modem that matches with your update and that might work better in this region vs the previous one.
Please list the Alliance rom version and baseband version here in case it's relevant to your issue.
More info
Im not sure if this helps but looking through the build.prop file in the system folder my ro.product.local.region=GB
When in recovery mode the region is set to XTC (Philippians) using mutli-csc.
Also my IMEI number seems ok and is NOT blocked.
Cheers. Yetti :cyclops:
Baseband and rom etc
Thankls for your reply!
Sorry when you say "under the battery symbol" do you mean in /odins boot script on the device/ or /in settings on the phone/?
Baseband is g900TUVU1ANCH
Build Num: AllianceROM_G900F_XXU1ANCF
If the "no network" issue can be solved with the current firmware that would be the most desirable solution but going through the flashing process may be a good idea for my learning process, and will help with future updates.
Do you think getting back to a stock rom would help me?
tHANKS AGAIN!:cyclops:
Model confirmed to be g900t
Sorry i didn't understand the "under the battery" thing. I was lost in software world. The sticker under the physical battery says SM-900T so i guess that confirms that it is a t-moble verison (and the baseband is therefore correct).
I will try to flash the T-Mobile stock image to the phone and see if that works.
Also i will try to flash a modem (after i work out which one i need).
Cheers, Yetti :cyclops:
Current status.
Flashed the stock T-Mobile firmware to the phone. No success.
Flashed new modem to the phone. No success.
Will go to the T-Mobile store tomorrow to see if they can help (I doubt it but i have to exhaust all the options).
Any more help would be appreciated...
cheers, yetti:cyclops:
By under the battery I mean like to take off the battery cover of the phone and pull the battery out and look at the sticker found there.
G900t.

Click to expand...
Click to collapse
Yep it says g900t (see above)
As per flashing a modem. I have heard that it is possible to flash any modem for any version of the s5 to the phone. Some work well and others not so much. I have tried 2 T-Mobile modems (baseband) the G900TU1ANCH and the G900TUVU1BNG3 with no success. Do you have any recommendations for a modem to try (or even a custom ROM that might help?)
Cheers,
Yetti :cyclops:
I know that you mentioned they refreshed the service for your number, but do they have the correct IMEI in the system for your account? Metro makes a big deal about that now and you can't just take your SIM from another phone and pop it in a new one and go like you can with pretty much every other service (Cricket is like this too now).

"Not registered on network" problem with correct IMEI

Hello All,
I am from Pakistan, and I have a Galaxy S3 I9300. I have upgraded it to 4.3 JB recently. I have flashed XXUGNA8 4.3 firmware for Pakistan, downloaded from sammobile. Everything works fine but I cannot make any calls. It says "not registered on network". However when I call the number from another phone, it rings but s3 doesn't receive any call.
I have tried many fixes given on the internet to no use. My IMEI is not corrupted. I have the same IMEI on the back under the battery as in the phone itself.
Any help will be much appreciated. Thanks.
Problem has been solved by flashing XXUGMK6 firmware and the patched kernel and modem given here.
