unlocked tmobile phone now locked but not asking for unlocked code

ive posted this in jpc bug thread but no one has replied and if in the wrong place please move.
ive got a galaxy s from tmobile and is unlocked ive put in a giffgaff simcard and everythings good
i then flashed jpc thru kies and like a few poeple lost the product code and ime.
i flashed back to official jm1 and then after about 2 days my phone wont send or accept texts and i cant call out or receive.
i thought because the ime was corrupt my phone was blacklisted as i tried with different sims but it said "not regestered to network. so i decided i was going to brassneck it and phone tmobile and say after i upgraded to official jm1 it fooked my phone.
but met a friend today with a tmobile simcard and asked if i could use it just to check before i phoned tmobile and guess what it worked no problem.
the giffgaff simcard works on my kaiser winmo phone
the phone doesnt ask for an unlock code when i put my giffgaff simcard in and i can use market and internet no problem
if it doesnt ask for an unlock code how can i get my giffgaff simcard to text and call as i dont want a tmobile one
regards

that is becuase you cannot goto jpc and then back as you loose your imei.. unless you backed up your efs directory your are now hosed.. unfort. you should have done some more reading before the flashing..

with all due respect i know the pitfalls of flashing and i was one of the first to flash it so all the pros and cons of jpc wernt there.
im asking about the texts and calls and the simcards
i wasnt asking about ime
so read what i wrote then if you can help then do so,
if not dont give me a lecture about it
regards

i am answering what you wrote about.. the reason you phone is acting funky and locked in my opinion is that the network is not accepting your screwy imei and that is why texts and calls are not working..
or possibly more than one person on your network has the same imei which would also cause problems.

please read again
its working with tmobile simcard but only data with my giffgaff simcard
i know about the ime problem thats why i never asked about the ime so instead of telling me to read more i think you should practice what you preach
once again
i am asking why its not asking for an unlock code when i put another simcard in apart from tmobile simcard
regards

maybe because of the obvious that another person is on that net with the same imei , but not on the tmobile net or tmobile doesnt respond in the same way.
or somehow it got relocked to t-mobile.
maybe try a 3rd sim to isolate the issue?

yes only tmobile sim works but as i said when i put my giffgaff sim in i cant send texts or call but can use internet
ive tried an orange sim no dice it acts the same as the giffgaff
so for some strange reason the other sims are half locked as it doesnt ask for code
serves me right for downloading jpc then downgrading before most people had tried it
regards

sounds like it still may be locked or half locked have you tried the unlock methods used on the captivate or your phone to see if you get any results.
the internet wifi would still work while locked i think? so that is no suprise...
(you could always change to tmobile
i have never unlocked but if it doesnt ask for code i assume you cannot try the lock methods above.. is there a way to force it to the unlock menu?
luckily if this ever happens to me i have a copy of the efs directory on my computer (I read about someone loosing their imei even b4 the latest froyo update.. dont remember why but i quickly made a backup)
also you could do like someone else said in a forum flash back to stock.. then reflash and unplug in the middle to purposely try and brick it (but i think even in that case bootloader still works) but feign ignorance about flashing and just bring in to t-mobile store and say it is not working.. hopefully they will reflash with everything and fix imei as well.

[Q] Wildfire o2 sim problems

I have a wildfire s that has been properly unlocked, however it will not accept my o2 sim- i dont mean that I can't get the mms or internet but it wont accept the actual sim - when it ask me to choose a network and i pick o2, it simply says that the sim does not support connection the the carrier - i have a brand new sim 3g ready.....................someone, please help...

what does 'properly unlocked' mean ?

I say you might have unlocked the bootloader,bit the phone still has SIM lock.

hmm, so you saying if i go back to the shop and get them to unlock properly, it might let me use the o2 sim???
is there anything i can do....having only a modest knowledge of these issues?

and in reply to properly...sorry i wasnt specific - i meant that when you put an o2 sim in and turn it on...it doesnt ask for a pin or code to unlock the phone??

Well did you buy it in a O2 shop? If yes,then there appears to be a problem with you handset. If you DIDN'T buy it in a O2 shop(which means any other,T-Mobile,3,etc.) Then you're out of luck because it it probably SIM locked to that carrier.
You should bring back the handset back to the shop and ask them to remove the SIM lock.

ok, so here we go...
Went to the shop and they say the phone is unlocked. When i put an o2 sim card in, it does not require a pin when the phone switches on.
It works with tmobile sim, orange, virgin just not o2....
so it is unlocked just wont take o2.....
any ideas why?
its originally a tmobile wildfire - spoken to tmobile and they say they have completly unlocked.....

do you have any other o2 sim to test it ?
you should also go and change your sim, might be rly the SIM problem ...here changing sim costs 10 bucks, i hope its free in your case.

im afraid im a step ahead - all o2 sims dont work - i had a brand new 3g sim sent out by o2 and have tried a pay as you go sim on o2 - still wont work with any o2 sim....
any ideas?

a ok, i didnt read that one... lets try to keep this on one thread. why dont you try flashing stock rom again... i mean its worth a shot... i guess you dont use any custom roms atm ? or even try flashin any custom rom, just to try it ... if it doesn't work then, well, we will see it's a very strange problem.
did you try connecting with 2g, and not 3g...
or maybe changing setting in *#*#3646#*#* then phone information, then set preffered network type... and try changing those also ... First try this, and if it doesnt help then try what i wrote above.

ok,well - had a read of your suggestion and only a slight problem with it...i am a real beginner when it comes to this so apologies but rom flash???
Also looked at the *#*# suggestion...unsure how to do that - did try typing that into the keypad on the phone part but it didn't do anything..
apologies im not up to speed..any way to simplify for me?

oh, and also someone has suggested going into the bootloader so i took out the sim and battery, put it all back in and held down volume and power. at the bootloader menu, i selected simlock. when i pressed it the following was displayed..
fat 32 init ok
open mccmnc file fail
open cid file fail
process done, reboot?
does this help explain anything??

i guess you didnt unlock via xtc clip... you should write the code that i told u on dialer pad, it should immediately open a meny, i will make photos when i come home as a more detailed guide k ?

ok, just to save you some time if you dont need to spend it - the phone was unlocked at a local shop - no idea how they did it - although im guessing badly...
i typed that code in - when i enter the final * the code just disappears and it does nothing. I did enter the code without the last * and it said mmi running but then said incorrect mmi...

well, you should give it a go, since i dont have an idea what could possibly be wrong

ok, well have done several things.
i) master factory reset - made no difference - o2 sim still wont work
ii) tried to connect the phone to the pc but even with htc sync installed the phone wont connect to the pc
so it looks like we're stuffed here???

Guys help. Noob here.

Hey guys, i just received my Sony Ericson Xperia Arc S from japan (docomo). I just boot it, everything is fine until I insert the sim card, Im from Philippines and I'm new to android phones so i can't tell if this phone is unlock to all sim. I tried to scan the network and it detects all of the carrier in my country but i always prompted to this after i choose my carrier "your sim card does not allow connection to this network".
Your response will be much appreciated.

try with some other carrier sim cards on your phone...

Your phone does not have to be rooted to be unlocked. A carrier unlock is totally different. it allows you to use any sim card in your device. Rooting gives you access to the hidden file system that actually runs the phone.

I think you should contact your cell provider to replace the sim.

first try it with a different carrier's sim. if its working then ask your provider for a sim replacement. if its not working then your phone is probably carrier locked. (of course if reception is fine at your location)

upgraded to ICS now have sim card problem

Hi All:
I've upgrade to ICS using the Samsung KIES software. Now my phone is saying my sim is not registered on my network. and I keep getting an unlock screen whenever I reboot the phone. Also in my notice bar at the top it says : "Invalid sim card. Network locked sim card inserted." This sim card worked find with gingerbread before the upgrade but now is not working,
Any ideas what I can do?
thanks,
Amsu

it relock, sometimes happen when upgrade

Try the "galaxy sim unlock" app from google market to unlock. One of the members have confirmed it working http://forum.xda-developers.com/showpost.php?p=36613342&postcount=4 . At 2 euro's i think it's the cheapest unlock available.
Not sure though the method used by the apk to unlock. If want to be safe then buy the unlock code from ebay.
BTW this post belongs to general section and not development.

Thanks for the info. I ended up buying an unlock code. Now it works. Sorry about the post in the wrong section of the forum.

How come there's no 'keygen' yet to unlock for free..?

[Q] Xperia ARC "No Service" error on TMN Portugal

Hello guys,
I have a problem with my Xperia Arc that I cannot find the answer on the forums.
My ARC is originally from MOVISTAR Spain and, after unlocking has been working great with VODAFONE Portugal.
Now I´m changing to TMN and that´s where the problems started. I´ve keept the same number (91) and therefore I went trough a "Portability" process to TMN. Last Friday the process was completed and my VODAFONE SIM card was disconnected.
TMN delivered me a SIM card to exchange. As soon as I did it the phone recognizes the SIM card, I put the PIN number and apparently all is OK.
But, there´s no network signal, and I cant make or receive phone calls or SMS. Everytime I try to call it says "Out of service area". This SIM card works normaly on my wifes LG Optimus Black.
My phone works at 100% with VODAFONE SIM cards and doesn´t work with TMN SIM cards. Despite it´s unlocked I´ve unlocked again the bootloader via Wontanserver. No sucess!
Strange thing though... I have 3G internet signal and I can navigate the web. Cant make phone calls or send SMS!!! Please Help!!!
Thanks in advance guys for any contribute.

When you say you unlocked it do you mean unlocked the bootloader or you also sim unlocked?

Already did! The TMN SIM card works on another phone, not in mine!
On my phone works VODAFONE SIM cards (tried various) and the TMN SIM only works for 3G internet connection, not phone calls or SMS...

HELP
Does anyone know how to fix this?
I've read somewhere that this was fixed in another case by putting an unlock code.
Do you know if this can solve my problem? If so, where/how can I get this "unlock code"?
Thanks again.

wontanserver server removes both sim and bootloadel lock, there`s no question there. now, since you have an unlocked bootloader, why don`t you try and flash kernel again ? or try and flash the stock rom, maybe you have some MOVISTAR crap and somehow block your calls, though i doubt that ...

Thanks for your reply. I've already reinstaled the ICS latest update trough PC companion, which "cleaned" my data. And... no luck there.
Does this process equals flashing kernel or stock rom? If so, I can always flash a diferent rom or kernel, do you recomend that?
Thanks for your help m8. I'm really in a jam...

except from vodafone sim cards, is there another sim that work ? are you positive you`ve made the right steps when you unlocked you`re bootloader ? try other sim, except form vodafone or TMN, make sure you don`t have some kind of network lock.

Yes, all sim cards work great with TMN sim cards as exceptions. I've tried old and new TMN sim cards. No luck! 3G signal for internet but no service for calls or SMS.
I´ve ordered a CHECKMEND report to see if my IMEI could be blocked/blacklisted by TMN and it came out with 0 problems!
Have tried ti change baseband, kernel and ROM, unlocked via WONTAN and... nothing! Now I'm back to stock ICS and stuck with the same issue... :crying:
Can anyone help?
Thanks in advance.

Do you resolve this issue? Mine is happening excatly the same thing. Nothing seems to work @Gsantoz
