At last I Found solution to enable Reliance Jio VoLTE for m8,

1.) S-OFF your M8 using SunShine.
2.) Change your CID to Super CID.
3.) Change you MID to 0P6B12000
4.) Download the AT&T lastest RUU from
http://dl3.htc.com/application/RUU_M8_UL_M60_SENSE70_ATT_MR_Cingular_US_6.20.502.5_combined.exe?_ga=1.176217506.667414554.1488534807
5) Install RUU to your M8...

You can now call directly using dialer. (No need to use JioVoice App for calling or SMS)...:fingers-crossed::fingers-crossed::fingers-crossed::fingers-crossed::good::good:

SPRINT n Verizon versions are Cdma/GSM versions but 4G/LTE only works on CDMA…

This is false information. CDMA is a completely different network type from GSM, as well as from LTE. A number of folks have gotten the Sprint M8 to work on LTE networks (aside from Sprint). However, LTE compatibility is a tricky thing. Even with the proper band support on the GSM version M8, I've seen a lot of folks not achieve LTE on their local networks. Let alone VoLTE, which is even more complicated (carrier specific deployments, etc.).

have GSM Variant Of Sprint M8

When an M8 version is called "CDMA version" it means the phone supports CDMA in addition to (at least some) GSM and LTE bands.

Sprint is a CDMA network. There is no such thing a Sprint branded device that does not support CDMA.

Well I believe that this is not possible. Because the Htc One M8 Sprint has hardware restrictions. Then the 4G network will work if your carrier has the same bands used by the Sprint carrier. I also have an Htc One M8 Sprint and M9 Sprint also tried converting M8 to Dev Edition and almost briked my device. So really settle for 3G band or sell yours and buy a Dev Edition. If you know a way to bypass those restrictions that will a help for thousands of people like us who want to have a fully working Sprint M8 n M9 on GSM 4G LTE VoLTE ????

You're talking about a couple different things now.

First of all, the Sprint M8 already supports some (not all) LTE bands, out of the box, with no modification. Maybe the bands supported (there are many used by various carriers worldwide) are not the ones required by your local carrier. Or even if it supports the proper bands, that is no guarantee you will have LTE service on your local carrier; due to carrier specific deployments of LTE. From what I've seen, LTE support on various carriers is very tricky and there is no consistency (even when the device supports the proper LTE bands).

I'm fairly certain that some folks on here have had success getting LTE to work on their local networks on the CDMA M8 (at least Verizon). But your results will vary depending on your local carrier and the factors just mentioned. Plus, the Sprint version seems more locked down than the Verizon M8, so yet more complications there.

Second, what you did trying to convert the Sprint M8 (which you did not previously mention, and a completely separate matter) by flashing RUU, firmware, or radio from any other M8 version is definitely impossible, as you mentioned due to hardware differences; in addition to different radios, different partitioning, and different kernels. This is simply the wrong way to try to change band support on a CDMA version M8; which will not work and may (as you know) possibly lead to a radio brick (and sometimes a permanent radio brick).

There are some possible mods to modify band support on the CDMA variants. However, your results again may vary. In particular, it seems the Sprint version is not particularly compatible with such mods. But here they are, in any case. As always, proceed at your own risk, if you so decide to. And only after reading through the threads and understanding properly :

    good share the link of AT&T RUU

    All the AT&T RUUs are linked here: https://xdaforums.com/showthread.php?t=2751432

    Keep in mind that the AT&T stock ROM is full of ATT crappy bloat apps, ATT branding, and carrier imposed limitations (no WiFi hotspot/tethering being on of the most important ones). I personally can't stand the AT&T stock ROMs. But if this is what needs to be done for VoLTE, and you really want that, so be it.

    Also be aware you need s-off and to change CID (AT&T CID or SuperCID) in order to flash an AT&T RUU.

    ---------- Post added at 09:33 AM ---------- Previous post was at 09:31 AM ----------

    Now there's the minor issue of no other custom ROM supporting this, and no current AT&T based custom/debloated ROM :/. Still though, can't really complain

    Root will allow you to easily debloat, as well as remove a good number of the other crappy ATT "carrier customizations".
