[Q] Signal drops after network unlock - Galaxy Ace S5830 Q&A, Help & Troubleshooting

Hey guys,
I unlocked my S5830 via IMEI code and it seems that the device keeps getting signal drops. I selected the right network and also entered the device's number in the proper section.
Is there something else I must configure? I unlocked my S II via a hardware unlock and as soon as I put my SIM in it, it was working fine. I'm really wondering why I'm getting a different result on the S5830.
Thanks!

Does anyone have an idea what could cause this?

[HELP] Sim Locked!!!!! PLEASE HELP!!!!

This morning I updated my note to 4.0.4
After updating it suddenly I wasn't able to make any calls or messages. I did some research and I have discovered that my phone had suddenly re-locked itself and is unable to allow my sim to work with it.
After doing more research I have rooted my phone and tried the Galaxy S unlock (which supposedly worked with the Note), and ended up with something like the attached picture. I see random icons but no specific code.
Here's a little background info that may be useful.
I bought this phone over in HK while I was there for vacation. The network lock occured when I first bought the phone but then the store that I bought it from found a way to fix it (without rooting the phone). Even when I upgraded to the OTA ICS there was no problem at all. I don't know why suddenly with this minor update it reset the network settings.
When I look into the mobile networks on my phone's settings a window pops up saying "Insert SIM card: Insert SIM card to access network services".
Which to me was kind of weird since I have inserted my sim into another phone and is able to make phone calls just fine.
Please help me! I have no way of contacting that store that I bought the phone from and I'm in need of getting my phone to work asap.
I am not lazy or anything, I have spent the last few hours trying to figure out how to solve this problem.
I have no experience in flashing a new rom and I really don't intend to do so unless i have no other choice.

You can - I believe - Downgrade to GB and run the unlock tool mentioned in that thread then upgrade again to your ICS..
Will this help?

[Q] Call ended before dailing starts

I bought a second hand GT-I9305. After the first boot I dicided I wanted to flash it with the CM nichtly. I first rooted the stock rom, flashed a recovery and then flashed CM. Now the problem is the I can't make calls. When I dial a number the phone responds with 'call ended' before it even starts.
I don't know if the phone worked to begin with, the first thing I did is flash it.
I've tried different roms now and reverted back to the 4.3 factory image. None of that fixed the problem. I've also tried putting to 2 or 3G only which didn't help either. My phone still shows an imei number.
I'm completely aware of the fact that I might have done something very stupid. I flashed android devices before but I'm the type of person who reads the manual when it's to late.
Does anyone have a suggestion on how to solve this problem?
I'm usint T-mobile on the EE network in the UK.
Problem still unsolved, more information
I'm giving some more information as the problem isn't solved yet.
I'm on a Pay as You Go sim that works fine in another phone (HTC Desire S). I've now also try to downgrade to 4.1.1 but still no luck. I've also tried different sims but the problem occurs with those sims as well.
The phone looks to be registered to the network, at least that's what it shows. Also, data works, I get a 3G and H+ connection,
I'm more than happy to provide more information. Any help is greatly appreciated.
SIM unlocked? Google xda sim unlock GT-i9305...
Phone not locked
Thanks for your reply. The phone is already unlocked.
IMEI blocked? If you're in UK try www.checkmend.com/uk/ it'll cost you 1.99 but might save you time & effort...

Sam here, call me cynical but happened 6 months after phone ran out of warranty. Done all the basics, diff SIM from different provider reset phone, even re-flashed phone and no joy, tried all the modem software going and phone will only work on 2G. Samsung support said take it to repairers hmmm wonder what that's going to cost. New phone, New manufacturer I think. This is 2nd Samsung ive had issues with
I've only just got my first Android phone from a mate after obnoxiously using iPhones for years+, an S5 Mini that lags and ****s itself at every moment. I've now got a gangsaf little unit learning anything I can about this phone and after all my errors, not once have I seen this.
Just for relevancy, I have a G800Y model but I'm using one of the two kernels I could find that looked decent which the devs have listed under G800F and as far as I can tell or what I've read, there's no real difference other than a difference between the LTE bands they can access (someone please correct me if I'm wrong). If it would be so much as to ask what exactly is the software specifications of both of your devices? By this I mean:
- What ROM are you running; [Stock] or [Custom]?
- Have you rooted your device?
- Have you tried finding your device's most recent stock modem software?
- Did anything lead to this or is there anything you believe could have contributed to the occurence of such a problem?
- What carrier are you with in what location? If you do not wish to say for whatever reason, have you tried a search for devices with similar problems and a possible resolution method?
Hello, i have stock rom, IMEI is intact, not rooted,
Basisbandversion G800FXXU1CQB2

AP: G800FXXU1CPL1

I can receive the Providers, but can not connect.

Won't stay registered on network

My S5 Mini SM-G800F won't stay registered on a network, it registers initially but after a few seconds drops to 'Emergency calls only' with the notification that the selected network is unavailable. The signal strength is fine and the sim works in other phones. It's an unlocked phone, using a different network sim produces the same result. Bought it secondhand just over a month ago and it's been fine up to to a couple of days ago, done a hard factory reset but the issue remains.
Ideas for a fix?
This may or not be similar to an ongoing issue I have with my S5 Mini - See below :- Has your IMEI changed to the below at all - 350695200123951-01 ?
"Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !! "

No change to my IMEI, consensus seems to be that it's probably a faulty SIM card reader.
