[Q] HTC Desire 200 - General Questions and Answers

Hi to all
I've bought HTC Desire 200 , but it seems to be locked for only one operator. At first, it couldnt recognize any other SIM card except the original T-Mobile sim card. Then i downloaded bootloader from htcdev.com and did everything exactly as it was written. After copying the unlock_key.bin, i tried with other sim card, but no luck. Only this time it was recognized by the phone, but i need sim network unlock pin.
Can anyone help me?
Thanks

I got the 'STRING: NOT FOUND' error on method one, so I moved to ADB Guide method and successfully unlocked it.

If you unlock the phone, it will still work with the original SIM card.
One possible reason that the other T-Mobile SIM didn't work is that it might not have been a newer 4G-capable SIM card, or the contacts became dirty ( they can easily be cleaned with a pencil eraser).

Htc Sensation No Sim Card Error/Can't enter network unlock code

Ok so i tried the unlocking method 1 for my sensation and found my 8 digit unlocking code, however when i put in any other sim card rather than the one the phone is locked to is says no sim card in phone so i have no way of inputing the unlock code.
Any ideas?
Thanks in Advance
i think it states in the unlock thread that it wont work with ALL sensations
Thanks for the reply, yes for some people method 1 just shows a date, but mine gave me the 8 digit unlock code.
The problem is the phone is locked to Meteor but when i insert any other sim then a Meteor one it says no sim card in phone, it should ask to enter the 8 digit network unlock code which it doesn't because its not recognising the sim card for some reason.
mine too, not detect the sim card..
Did you solved the problem?
regards

Did you put the code in with the meteor sim inserted?
you could always just flash another ROM and that should fix the issue, I know it's a bit drastic but if you really want to use another carrier...

Sorry for only replying now, still not resolved, how would i put the code in with the meteor sim in it?
Ive already tried changing the rom and tried the method 2 unlock but it still won't recognise any other sims apart from meteor ones.

(SOLVED) Sim not detecting/Insert a valid sim card on your phone

Hello there, I am not new to xda but this is my first post. I've a question regarding my M8 Verizon bought from ebay. Its been a year now and everything was going well since one day I accidentally did s-on and locked the bootloader while using HTC ONE M8 Toolkit by Squabbi.
Then I again s-off'd my device using Sunshine method (firewater didn't worked as it was discontinued). So I paid 1600₹ to get my device s-off'd and unlocked bootloader. But since then I am unable to use any Indian sim whether airtel, idea or any other. I tried many possible solutions found on the internet as well as here on xda. Like I flashed firmware (old and new both), flashed radio firmware files old and new both but no luck. Either I restored my device to stock Verizon rom using the RUU provided by Dottat. But I couldn't find any luck and I'm still unable to use my sim card. My phone is unable to detect it. My device doesn't even pops up any notification for sim card now. Please Help. :crying:
Is there any solution for this? I'm in a need of this.
Waiting to be helped as soon as possible.
Hi,
I do not know if same pb...
Phone is working fine on Lollipop on european Gsm/LTE (sometimes going back to cdma by itself, a bit boring), and is asking for SIM pin number.
When going to marshmallow (by RUU or by OTA) the sim is deribed to be absent or invadid, and It did ask for the SIM pin number
I did not find any clue...
regards
After a lot of tries, it finally worked. And the sim is now detected. Thanks to Me.

I disassembled my M8, then replaced the sim reader inside the phone, then removed and reinserted the flex on the board. Then turned on the phone, and edited the system file located inside root/system/customize/ACC/default.xml to change the value of sku_id and region located at last in the file default.xml
You can search on google for SKU LIST XDA. It will show you the list for all regions.
