Im on 0420 build. Sees SIM card but does not sees any number on it. Checked with another device and verified SIM has contacs. Any fix for it?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] Skalexs:
Easy. Both ROMs are good ROMs. Personally, I had some UI lags with RR, maybe because of substratum, im not sure.

Lineage OS by nijel is smooth and for me, bug free, but less customizable than RR.

Here most users don't feel lags in RR so, the best you can do is try both and decide yourself. It's really easy and fast. I use to change ROMs almost daily, but I come back all time to nijel's Lineage OS.

It's just my opinion :good:

Jio VoLTE and LTE is working perfectly on your builds, never had any complaints about it on your build and Linkz77 fix for video recording camera is working without interfering the VoLTE.

Can't say about H+ fix because I never needed it on your builds, I get all the symbol on my network (E, H, H+, LTE) while using your RR ROM.

Could someone please confirm this, is there ota support or not for "Helium"? Or do i have to download from here every time?
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] ajsmsg78:
I don't understand what's breaking this myself. All I did was take your 16th Hydrogen build (which VOLTE is confirmed working), add in the video recording fix (including the Venus files for the Helium build), change everything in the build.prop from Hydrogen to Helium and edit the init.qcom.power.rc to enable all of the Helium cores in my last 21st build and yet for Jio users Volte is not working. I'm at a loss for words here.

Everyone keeps asking what the difference in the two builds are and that is the only difference. Maybe I'll have to put a disclaimer in my builds. "If you use jio your SOL." :)
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
No OTA support for helium, infact there's no official RR for helium, so you need to download everytime from here either readymade ajsmsg78 helium build or sawdoctor's hydrogen build and modify them for helium.

I'm also on helium and do the same
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
This reminds me of why I dislike VoLTE and has decided not to go down that route when pure VoIP solutions exist.

Some networks require special code given to the device OEM for VoLTE, which means that most products never see this thing unless they are branded. Some networks only allow 'certified' models to get it such as T-Mobile and the band 12 drama.

So there is a possibility that dead VoLTE isn't caused by anything on the device end but rather the carrier - be it because the device is 'alien' or because the network doesn't recognize the model for other reasons.

It could be so simple that VoLTE breaks just because of... the Helium itself - i.e. the carrier didn't 'certify' the model but Hydrogen only and when the device communicate Helium the network label it as 'alien' and VoLTE goes down.

This is why I think VoLTE is just a headache - probably the most locked in and sensitive solution for IP calling ever seen. Similar issues with WiFi Calling which also tend to require 'certification' and proprietary code submitted to the OEM.

What can be fine here is perhaps an experiment - try this:

1. A build with just the installation script changed to accommodate Helium. No other changes - i.e. core configuration for Hydrogen and build.prop saying Hydrogen. See if the network can be tricked. Stock RR kernel.

2. A build with the Helium changes bar one: build.prop says Hydrogen. Stock RR kernel.

3. A build like 2 but with Harfix - i.e. still Hydrogen in the build.prop.

I wouldn't be surprised in the slightest if the issue is Helium instead of Hydrogen. No problem with the ROM itself or the Helium conversion but simply because the network consider Hydrogen to be certified for VoLTE while Helium is not.

The Jio case is special since it is a carrier which rewrite the whole game in India by offering very good prices for a decent service - only issue is that they use VoLTE only for talk since their network is LTE only. There is an app for calling that can be installed seems to be a bit so-so in quality.

Had it been other carriers I would have say VoIP instead of messing with VoLTE or WiFi Calling but the Jio case is a bit special.

Thanks for the ROM, still simply perfection and pure speed and stability.
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Before anyone gets confused and starts complaining, VoLTE works perfectly on Sawdoctor's official hydrogen Builds, The discussion below is about the unofficial Helium/Hydrogen builds.

That's not the case here because I'm using VoLTE on Helium with Helium build.prop

Agree...

Tried Sawdoctor's build on my helium and VoLTE works - Core Configuration and build.prop is hydrogen and Stock RR Kernel, only installation script change so that it flashes on helium.

Tried Ajsmsg78's helium build (on his request) by replacing the build.prop from sawdoctor's hydrogen build but VoLTE didn't work. (no other changes made by me to ajsmsg78's helium build)

Even tried that on Ajsmsg78's helium build. (helium build is by ajsmsg78, build.prop is hydrogen from sawdoctor and Harfix2.2 kernel) but no VoLTE.

That's not the case here because I'm using VoLTE on Helium with modified Helium build.prop on sawdoctor's hydrogen build.

That's the reason Indian users are so eager to get VoLTE working on ajsmsg's Helium/hydrogen ROM.

You were kind enough to call the Jio4GVoice (app used for calling in absence of VoLTE) so-so :) but it has too many connectivity issues.

I'm also very eager/curious to find the reason and ready to help in any way possible and that's why I flash all the builds posted here by ajsmsg78 in hope of getting VoLTE working.

********************************************************************************************************************************

I'm on sawdoctor's 21-Apr hydrogen build with modified build.prop for helium and on harfix kernel and working VoLTE as you can see from the screenshot posted http://cloud.tapatalk.com/s/58fda95a41ea5/24%20April%202017%20125013%20PM%20IST.jpg?

[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
Perhaps the issue is... the 652. If it use the Hydrogen core_ctl then it becomes a '650' and it could very well be that the network has only been 'tested' with the 650 and a properly configured 652 identifies itself differently, thus becoming 'alien' and... VoLTE stops.

If so, then perhaps the only solution is special 'Jio Builds' of the Helium version with Hydrogen core_ctl and just change to the installation script and build.prop.

For other users, the regular builds (i.e. Helium core_ctl) is on offer.

What happens to VoLTE when Harfix is flashed instead of the stock RR kernel?

Since the Snapdragon is a complete chipset with LTE radio integrated it could very well be that simple: Helium core_ctl break VoLTE on some carriers - not because there are anything wrong with the script or the CPU but... because of the carrier only recognizing the 650. Just a longshot but VoLTE is pretty messed up as a standard with a lot of proprietary carrier vendor lock-in so my experience is that even the most simple things can cause a device to become 'alien' for a carrier. It is mostly an issue with the carriers rather than a pure device/software issue.

Sometimes only a carrier branded device can get VoLTE even if the unlocked version has the necessary support (the carrier simply deny access).
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
Don't know how MIUI is handling because on MIUI VoLTE works with properly configured 652.

I think it's better to leave the VoLTE alone for Helium because too many builds may confuse the users. Helium users who want VoLTE can use sawdoctor's hydrogen builds (like me)

on Harfix

Sawdoctor's Hydrogen build = Working VoLTE (even on Helium with modified init.qcom.power.rc to enable 2 additional cores)

unofficial Hydrogen/helium builds = Not Working VoLTE.

[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
So the "final solution" for the VoLTE issue would be a Hydrogen build with modified power.rc for 652 with Harfix and the installation script modified for Helium installation?

Do you flash the modded power.rc separately or packed into the ROM?

I think VoLTE is the modern version of black magic.;)

It was originally launched as a universal standard for IP calls over LTE (since LTE is a strict IP based network architecture) but was later messed up by the carriers by implementing different proprietary "add-ons". There are even devices where VoLTE was enabled in one stock ROM but then removed in the next per carrier request (this exact thing happened to the Galaxy S 7/Edge in Sweden).

So VoLTE is a quite complex chain of factors of having the "exact right" combo of ROMs, kernels, carriers, device models and internal configurations. It is not like other network standards where everything typically "just works" (and if it doesn't work it is a more specific problem such as a new ROM without working radio such as good old CM alpha builds before things got up to speed).

If the working recipe is a minimum change repacked Hydrogen ROM then it feels like such a slight "Resurrecion_Remix_2017xxxx_Official_Helium_VOLTE_Jio" would be the solution and then the regular ajmsg78 builds for everything else. Those who need VoLTE more than anything else (because they are on Reliance Jio) can flash such a build.

To ajmsg78: I wish you all the best and hope for a quick recovery.

My device is running as good as it could ever run on your build with the Jerry08 kernel tweaks flashed. Absolutely smooth and excellent battery life. It just couldn't run better because it just... perfect.

[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] paarkhi:
VoLTE works in official RR by Sawdoctor even on stock kernel

Yes for Helium users, modified power.rc is needed with Hydrogen builds from Sawdoctor because I tried Hydrogen from Ajsmsg78 but VoLTE didn't work (many other hydrogen users also has the same problem) but for Hydrogen users official RR with stock kernel is enough for VoLTE issues.

I'm using Jerry08 Helium script which I have modified further for 1 big and 1 little cluster for idle time and I flash that at the end after flashing harfix2.2

:D :D :D
[Xiaomi Mi Max ROMs, Kernels, Recoveries, & Other D] E90 Commie:
My power consumption using ajmsg78 Helium build, Harfix 2.1 (need that one for Kodi/USB-OTG access, which doesn't work on 2.2), Jerry08 tweaks and my own optimization with Disable Service and Privacy Guard are usually about 0.1% in standby. The ZolaIII tweaks are also good and I am still thinking about which one I should use - the power consumption seems pretty much similar, though but I have to do some more evaluation.

Regarding VoLTE and black magic: Try to get an unlocked device to run on T-Mobile band 12....

Don't get me started on the theory about how many LTE bands the world "needs" since it is just insane. LTE, VoLTE and WiFi Calling has become the new way for carriers to limit competition, freedom of choice and to get full control over their customers. This is also why I still consider LTE a "bonus". If it is there, fine. If it is not there, also fine. I am just not ready to restrict my device choices to a few branded models because of the newest form of proprietary vendor lock-in: Special LTE bands, VoLTE and WiFi Calling (the most extreme case is Freedom Mobile in Canada where the choice of "freedom" is... LG V20 or LG V20 if LTE is interesting on the network).

Till you guys start collecting logs you will not find what brakes volte... Simple as that...

My guess is it has nothing to do with mods itself but with the repacking of system image after modding which brakes system/vendor apps signatures. Example - qti-telephony-common.jar... try adding it post rom build and you get com.android.phone crashing all over the place.

So my humble advice... Start building proper helium versions from source and quit messing around with hydrogen builds like back in the days we didn't have any device sources available... This is ridiculous...

Hi nijel8!

I'm happy with your HELIUM builds!

PL go-ahead and give us HELIUM versions with all the MODS!

Those who want VOLTE, they have option of using SAWDOCTOR ROM, as it is proven by many comments!

Let us have 2-versions 1) VOLTE - SAWDOCTOR version for VOLTE 2) NON-VOLTE : Your ROM with all the MODS for HELIUM versions?

I hope all agree!

Rather than complaining, this is not working and that is not working, let us settle with the 2 versions,
