[Q] HTC DESIRE - Help! SIM Asking For Unlock Code

Right, I have a big problem here...
This morning, I downgraded my HBOOT to the 0.83 version on my HTC Desire. After doing this I then installed the origional Android 2.1 Eclair onto it. Everything went perfect until my phone restarted, and then suddenly after unlocking my phone it asked for a SIM Unlock PIN. I have a PIN on my SIM, but this is the PIN you enter to initally acess your phone as a security feature, and when I inputter this code it DID NOT work. So I need quite a bit of help with dealing with this problem. I have managed to get a temporary fix on the problem, by tweaking a bit and installing a different pre-rooted ROM, however I would like to run a Un-Branded version of Froyo 2.2 on my HTC Desire.
I have a British HTC Desire on Orange Contract <I Have Heard Orange Contract Sims Are Blocked?>
All help is greatly appreciated, first post aswell so I hope someone can help thankyou

[Q] Htc inspire problems with sim card

hi every buddy i have a problem with my htc inspire from AT&T i root it and installed a costume rom but now it dosnt want to read any sim card even the AT&T Sim card can someone tell me what I can do
Which rom are you trying to use?
I know this is a stretch, but did you ever put a lock on your SIM card? So if you boot up the phone you need to enter a code? Maybee a friend tried to get in the phone and for security purposes the phone burns out the SIM...
thanks man look the custom rom im using now is CoreDroid_Desire_HD_GB_2.3.3_V6.6_RV, the first one was gingerbread 2.3 and it works good with any sim card so then i put the coredroid hd but i dont know what happen to it and now i restored to original att software and i did the same steps but it cant read any sim card..
When you rooted, did you set S-off? If not, that could be causing the problem; one of the ROMs might have been from another carrier and set to only accept their SIM cards. When you boot into bootloader (volume-down + power) you should see something like this at the top:
ACE PVT SHIP S-OFF
If you don't see that, re-run the hack kit and select S-OFF from the menu.

[Q] Staying Sim Unlocked and flash stock Rom

Hello,
I have tried to find an answer to my problem and can't seem to find it anywhere. Hopefully someone here will be able to assist.
Ok So I have an HTC ARIA, sim unlocked, and rooted using unrevoked3, running Aria Liberated custom ROM. Here is my problem I am not NAND (s-0ff) rooted. I have tried running revolutionary and also unrevoked forever. Neither worked. The problem is that I have hboot 0.57.0000 and I need version 1.02.0000 to make those programs work. Additionally, I need the phone to stay sim unlocked as I am in Germany for the next 3 years and am using a German cell phone company. So what I need is eithor a way to NAND root with hboot version 0.57.0000, or confirmation that if I install the stock upgrade to Android 2.2 (available on the HTC website) that my HBoot issue will be fixed with out loosing my sim unlock. I purchased the phone on ebay unlocked, I am not nor have I ever been an AT&T customer so I don't know where I would go to unlock the sim card again if it should become locked, and I don't know the code to unlock it.
Thanking you in advanced

Desire S not registering on network

Hello,
I have this Desire S here which is on official 2.3.5 GB rom, sense 3 and unlocked. Everything else is working apart from the sim is not getting registered to the network and it keeps giving a "x" sign above signal notifier. I tried to manually register the sim "Orange" on its network, which it registered once and after 2 minutes removed the registration automatically.
can you please help me in this regard?
shall i flash the radio?
shall i flash the new rom?
or is it some hardware isuue (assuming it is working because i can search the operators manually.)
Hi few days ago,
I've had similar issue with my lady's phone, she just spilled some liquid ( ? ) over the phone
and when i opened it, the phone was wet inside...
There was no network at all..
I dried it up through the night, and it came back to normal...
You can try to clean simcard and phone connectors as well ( carefully )
If that's one of the above mentioned causes, there is a big chance you may recover your phone...
If the problem persists, you might also check

for more direct help
thanks for the tip. let me open the phone and give it a go... will update you if it worked or not
ok, i have checked it, cleaned the sim jacket, phone is not water damage either...
sim jacket is fine because it do ask me for sim pin code when i turn the phone on. the sim card is not blocked either.
can you please look into this issue for me?
thanks
Could you give more details? Such as how you unlocked the device? Any mods that you may have installed?

Just a thought....
Is/was it simlocked
Is your phone ( or its software ) branded ( carrier locked )
Is it still stock or rooted and modded already...
Could you specify the radio version- your device is having installed...

[Q] One S C2 stuck on EDGE after SIM unlock

Hi guys,
I recently had my One S C2 (Orange Romania) SIM unlocked by somebody with JTAG procedure (I don't know how that works, but it's the only one that does, no SIM unlock code option). After unlock the phone kept rebooting every minute so that person reflashed my phone with the latest software available:
RUU_VILLEC2_U_ICS_40_S_HTC_Europe_2.15.401.100_Rad io_16.21.20.02U_16.09.20.11_M2_release_286571_sign ed.exe
OTA_VILLEC2_U_JB_45_S_HTC_Europe_3.19.401.101_16.2 2.20.03U_16.11.20.24_M.zip.
Now the phone is working but I have on 3G connectivity.
I saw a possible fix here - http://forum.xda-developers.com/showthread.php?t=2160389&page=19 - but it seems to be for One S S4 version.
Already tried reinstalling RUU_VILLEC2_U_ICS_40_S_HTC_Europe_2.15.401.100_Rad io_16.21.20.02U_16.09.20.11_M2_release_286571_sign ed.exe, but no go due to bootloader missmatch (newer hboot on pone already).
Any help would be greatly appreciated
