Hello,
I have a HTC Desire 816v China Unicom. I am using the phone in India and in SIM Slot 1 i have inserted a CDMA Sim and i cannot receive any SMS or Send any SMS i have already unlocked the SIM from forum.xda-developers.com/desire-816/.../unlocking-htc-desire-816v-cd... I Also cannot change the network settings from 4g LTE to 3g. I have unlocked the bootloader and rooted the phone currently the bootloader says unlocked and S=Of. Can anyone help me out here ? is there any Rom which will help me use the CDMA Sim Slot ?.
P.S in the bootloader the version is A5_DWGL
Hi guys, recently bought the HTC Desire 816 prepaid sprint, achieved with the help unlock xtc2clip box. but now I get to do that connects to the GSM network, if I select the band gsm only in the menu * # * # 4636 # * # * not select, I tried to change ROM and many things I have read in forums but nothing works . could advise me as to enable the GSM bands.

what I need is to change the radio, I think that's the problem. here's why: THROUGH the "RF_NV_Manager" program could add GSM GSM bands and place it on the radio but as is for CDMA does not start, so I come to the conclusion that I need to change radio, which is currently 1.47.40.0224.
if anyone has any unlocked GSM radio that could give me please
and for which I could generate them need to unlock SIM files or S-OFF with my Box Xtc2 clip.
IHave an idea but not sure if it would work or not. Also a warning..it could brick your phone possibly.
Since you have s-off, you could change model id, set super cid and then flash ruu of the model of htc 816 that supports gsm or gsm and cdma. See if it works. If you have a tool that lets you back up efs, non volatile memory data then please do back it up. Does xtc2clip support that and also repairing imei/meid in case it gets messed up? Good luck if you decide to give it a go.
I also have been trying to enable gsm and LTE on this phone but no luck so far. Htc seems to have put in special efforts to lock down gsm and therefore enabling the bands alone doesn't work. I don't have s-off so I can't experiment much.
I have another idea that's not risky. Just change the model id to the 816 model that supports gsm or gsm and cdma. Then get the build.prop file for that model and use it instead of your current file. Try it and share the results.
Our phone has a place for second sim too. I'm not sure if SIM tray is there or not but if we could convert this phone to a cdma+gsm model, it would be great.

thanks for your idea, I am looking for a RUU for this model in its unlocked version but HTC page only meeting the sprint, if someone could give me some link please.
Sprint has not unlocked gsm capability of this phone and therefore you won't find ruu that has gsm unlocked on htc site.
So what will we do to unlock it

Any luck on enabling the gsm band yet?
Are there by chance any roms that would allow for a psuedo sim unlock for gsm sim cards on the Sprint variant of the M8? I have FusionRom V6 for the LS990 Sprint variant and there is absolutely no work involved in popping an ATT/Tmobile/international sim and getting it to get HSPA+/LTE.
Changing roms will not sim unlock a phone unfortunately
Hi.
First off, thanks for the help!
Here's my first question:
Most everywhere I've looked I read people stating that CDMA phones DO NOT have sim card slots.
Well, I've purchased a prepaid Moto G from US Cellular. It is CDMA and it DOES have a sim card slot.
Matter of fact, it comes with a sim card to install right in the box.
SO...
I don't understand what does that mean?
Do CDMA phones now come with Sim slots?
Or is this some kind of CDMA/GSM hybrid?
---------------------------
Hopefully getting that cleared up here's my other question:
I want to unlock this phone. I tried inserting a different sim card but the device never asks to enter an unlock code.
Would there be any Roms or any other way you could recommend I could try to unlock this phone?
Thanks again for the help!
I installed Viper one for my HTC ONE M9 sprint and I installed the T-Mobile version on it, I have super cid enabled. But my T-Mobile sim is not being recognized in my M9, What am I doing wrong? The Sim card works, I put it in my Galaxy s7 and I get service. Please anything! I'm really stuck right now. Does the M9 Sprint take a different type of nano sim?

Sprint is CDMA, T-Mobile is GSM.
