HTC Desire 816 a5_chl (Virgin Mobile) trying to network unlock! - Desire 816 Q&A, Help & Troubleshooting

I have an HTC Desire 816 from Virgin Mobile currently on stock Lollipop. It was previously on CyanogenMod but I switched back to unlock the network. I'm trying to unlock the phone with a foreign sim card. I've been trying to get the unlock code prompt to show up by booting with the unauthorized sim in. I get a prompt to put the sim card's pin in, then I get an "invalid sim" notification but never an unlock code prompt. The sim is currently activated & it works in a different phone. Also tried a different sim that also has service, but same thing.
Tried rooting the phone & disabling system write protection to use this: http://forum.xda-developers.com/showpost.php?p=44255011&postcount=10
I also tried different combinations of dial codes to get the unlock prompt to pop up. Nothing seems to work.
I thought about trying to get S-OFF next and checking the CID, but would this make a difference? No idea what else I could try.
Any help is appreciated, thanks!

I spoke with jcase he said sunshine should work now but it is untested on a v.m version,sunshine has network unlock for sprint devices and that's what v.m network uses

Help! Entering TMO USA TP2 SIM Unlock code, where do I enter it?

Guys I'm over in Europe and attempting to use a vodaphone SIM, I'm running NRG's ROM and radio 4.49.25.17.
T-Mobile had kindly provided the SIM unlock code for my TP2 prior to my trip but when I put in the Vodaphone SIM it doesn't prompt me for an unlock code?
Do I need to manually enter it somewhere?
I think its supposed to prompt you with a screen asking for the code, make sure the Vodafone sim is properly inserted and if that doesn't work you can try looking up the phones engineering mode.
Is the device booting into Windows Mobile & usable with the other SIM card installed? Where did you buy it? Sounds like it may be unlocked already. Anytime I put the wrong SIM in a locked device, on boot up I would get a message for the unlock code & device was unusable, would not progress past this screen. You had to either enter the unlock code or reset & remove the SIM card.
First, check if your device is unlocked by going to Start>Settings>System>Device Info and on one of the tabs, it should say unlocked somewhere. Or, you can check it by downloading ATCommander onto your device and entering [email protected]?40 into ATCommander. It should return 0 if you're unlocked. If it returns 1, you're SIM locked.
Now, if you are still locked, try flashing the Stock Tmobile USA ROM, and insert the Vodafone SIM then. Hopefully, a dialog should come up with an area to enter you unlock code. On the Kaiser, you supposedly had to be running the stock AT&T ROM in order to get the dialog unlock the device with an unlock code. Hopefully that will work. If not, TMobile tech support could probably answer this. Hope that helps

[Q] Network Unlock code trouble

I have the network unlock code for my ROOTED Orange HTC Desire which says it is accepted when entered. Once the phone has booted on the non-Orange sim it doesn't receive a signal from the network and an error is reported when I try and search for available networks. Each time I reboot the phone I have to re-enter the Network Unlock code again.
The SIM card being used is active as I have proved it on another SIM free phone.
I am running Redux-2 2.31 ROM with the original Radio.
Has anyone else experienced this?
Does anybody know how to overcome the problem?
Thanks in advance!

Requesting network unlock hang

Hi guys, I'm trying to network unlock my M8 to use in Germany. I've inserted the card and typed in the network unlock code that I bought. Unfortunately, it is hanging on "Requesting network unlock'
I have tried factory resetting the phone.
What can I do?
Thank you
Are you stock, which carrier?
AT&T Skydragon rom
Try stock rom if you can see if that helps. Do a backup of your current rom, flash stock then restore backup
I'd suggest go back to complete stock also.
thanks, going back to complete stock worked. However my SIM card is locked every time I turn on the phone.
What do you mean your SIM card is locked? Do you mean you have to enter a pin to unlock the screen?
Network unlock requested?
Hi man,
I have the same problem.... Canadian Htc One m8 google play edition locked to Bell... I have rooted and unlocked bootloader... unable to s-off...

Tried everything and nothing helps....
maybe some developers here can figure it our...

[Q] HTC one m9 unauthorized sim card

Hello guys, sorry to bother. I am contacting you to see if someone can help me, i´ve searched and searched the web without any luck. Almost three weeks ago i got here in Mexico an HTC one M9 from Telcel, I have two mobile phones two lines one telcel one iusacell. I needed to change the iusacell phone but did not like what they had. I got the telcel phone HTC one m9, and it was unlocked from telcel, i put my iusacell sim and worked great. Strangely after two weeks, the screen intact, with not a bump and a glass cover, internally failed and i sent it to a authorized center from the provider, they sent it to HTC and HTC sent me a brand new phone.
This new HTC one m9 works perfect with the telcel chip, i inserted the iusacell chip and it gave me message "UNAUTHORIZED SIM CARD, EC calls only". I assumed it was normal, went and bought the unlock code and tried to enter it, but i noticed it never popped the network unlock screen, it always pops the UNAUTHORIZED SIM CARD EC CALLS ONLY" message on the main screen and the only thing it lets me do with the iusacell chip is place emergency calls. no codes, not even to check imei.
I´ve been looking for support with no help, when entering the unlock code and hitting call (no ok button) it tells me its not an emergency call.
Searching i found that its probably that in the service menu (mode) they deactivated the network unlock screen, but i have not found how to get into the service mode of the phone, everywhere for older htcs they say its *#0011# but no luck, the only codes that work are the *#*#4636#*#* and the 3424 but none of them help me.
What can i do? I prefer to use my iphone for that line and use this phone for my other line which is on a different carrier.
Any ideas or help?
cheers and thanks
Ivan
They gave you a new phone, new motherboard and it's not unlocked. I would assume. It'll probably need to be simple unlocked again. With the first phone you had to request that it be unlocked right?

Strangely enough the first phone i bought came unlocked, i had purchased online the unlock code but when i inserted another sim i did not require it. The problem with this replacement M9 is that although i´ve already bought the unlock code the screen never prompts for the network unlock code. When i insert a different sim that from the carrier (telcel) it prompts an "UNAUTHORIZED SIM CARD; ER CALLS ONLY", i´ve inserted IUSACELL MEXICO SIM, ATT USA SIM
TMOBILE USA SIM all with the same result.
cheers

I know with the T-Mobile phones, or at least I'm pretty sure, we have to flash an international rom to get that screen to come up. Kinda sucks but maybe that's the problem?

Thanks I was considering it, i think its a possibility, although, i havent searched much but there is still no way to free the bootloader of an HTC one M9 and im sure myne is pretty locked up =(
cheers Ivan
You can unlock it or s-off , but a-off is $25. Unlock is free on HTC Dev unlock. It's pretty easy, have you used HTC dev unlock before?

It works I've used it. You have to select the very bottom option, it says something like all other models

I finally got the bootloader unlocked, root and s-off, now the question would be what rom should i flash in order to get the unauthorized sim card message out when i insert a different carrier sim, so the network unlock screen pops and i am able to enter the unlock code?
cheers and thanks

I used ARHD to unlock my T-Mobile m9. Prior to that I also wasn't getting the option of putting in sim unlock code similar to yours. However once you flash and sim unlock it, you can flash any rom and the sim unlock will stick. Good luck.
Sent from my HTC One M9 using XDA Free mobile app
Thanks =) i did manage to get a new rom into it ARHD and interesting enough when inserting a different carrier sim now I do get the network unlock code screen. I tested the pin i had bought and it did not work, I asked and they told me they will try to find it out. I did try a few more services to buy the code but they all tell me that they cannot find my IMEI in their database. This i find really strange, does anyone know what can it be? I need to unlock since i will be travelling to the USA and want to put a prepaid card into my phone.
cheers

I had the same problem as you. My HTC was originally from T-Mobile, I unlocked bootloader, flashed latest TWRP recovery, rooted and S-off'ed. After that I also set CID to BS_US001 and MID to 0PJA11000
After that downloaded Developer Edition RUU from http://forum.xda-developers.com/att-one-m9/general/att-developer-edition-ruu-how-to-t3086948 (use the 1.32.617.30 RUU.zip, using the 0PJAIMG.ZIP method), after that you will be prompted to insert unlock code and receive latest updates, hope it helps!

This is for not found service, http://www.ebay.com/itm/HTC-not-found-Unfound-unlock-code-for-Telus-Kado-Wind-Bell-solo-AT-T-T-mobile-/281679367246?pt=LH_DefaultDomain_2&hash=item4195660c4e
If you already bought and received an unlock code there is a big probability that you had a typo with your imei maybe. Usually when you receive an unlock code they tend to always work. Hope it helps
Hold on there's a tested and working free sim unlock in here somewhere! I have used it and multiple others, let me try to get the link.

Htc sprint prepaid unlock window

Hi,
Usually when we put a foreign sim card into a phone that is locked into a carrier, in my case sprint, the phone will ask me for a unlock code to put in. Strangely when I put another (bell Canada) sum into my new sprint prepaid phone it just remind me that the sim card is invalid but no pop up window to enter an unlock code. There is a website that will generate a unique config.dat based on imei serial and flash in hboot menu. This doesn't work unfortunately. I also paid sunshine to have s-off and changed my cid to the Super one 11111111, still not working.
Now I have sorta crazy idea. There are other variant of single sim roms that may be able to bring up the sim unlock code window but there is no way I can flash it since it always checks my darn model id and present a code 41 error in facebook. Is there anyway I can finally manage to enter an unlock code for my sim because I loved the phone so much.
Thanks!
I would like to do this as well with my Koodo Sim.
