Making volte work on Andorid Q Roms. - Lenovo ZUK Z2 (Plus) Guides, News, & Discussion

As I have seen many people are facing issues regarding volte not working on android q roms. This can be solved by following the below procedure.
1) Flash stock Zui 3.5 through qfil
https://drive.google.com/file/d/1xWGFtcMZhMeOAsmASj4fwJzzbHOZZwdj/view
2) Boot into the rom and make sure that volte is working
3) Now unlock the bootloader and without booting back into system go to fastboot and flash recovery.
4) Flash the latest twrp and then wipe data/system/dalvic/cache.
5) Now flash any Andorid Q rom and reboot to system
6) You will be able to use volte now.
Note:- Make sure your sim is inserted into slot 1 or else volte might not work.

Does it matter if the ROM is encrupted?
I mean i am on locked bootload, china dev 6.9.9
I want to move to global stable 8.0.1 .. so fastboot rom via EDL should work fine, isnt it?
How do I unlock my bootloader on cm14? You have mentioned in second step to make sure the bootloader is unlocked before flashing MIUI 6.7.21 but MiFlashUnlock cannot unlock the bootloader.

for that u need just 1 modem file to flash.. and everything is fine.
Or just backup every partition with alka before flashing cm14 and afterward restore it (ignore firmware) to have your previous rom back with the data and everything and no flashing required. People just overcomplicate things. I've done this with every single combination of roms and bootloaders ... And it always works.
Miui lp, miui mm,cm13, cm14, aosp, you name it

Still No VoLTE for Redmi2 8gb variant

Hello, I currently am using a jio sim as my primary sim. However, i tried all the methods suggested on xda but still no volte.
List of things that i have tried:-
1. Tried flashing the modem(doesn't work at all)
2. Flashing MIUI 7.5 version as suggested( V7.5.2.0.LHJMIDE_20160629.0000.25_5.1_global ) to be precise
3. Tried flashing another one of Redmi2 Prime's firmware(global developer rom)
4. And tried flashing several other ROMs(Orion OS, RR, Tesla, AOSP and DU) after doing step2 and still no volte support found
Can anybody help me?
@cypherx1998 Flash kitkat dev rom 7.1.5 or newer from fastboot, after it starts booting turn of your device and boot into fastboot, then flash the latest lollipop dev rom and boot into it, setup your device, then go to settings, mobile data (I think, it's where you have the option to change to 3g and 4g data) and enable VoLTE voice calls, after that, reboot into fastboot and flash TWRP 3.0.2-0, then go to wipe, advanced wipe, select:
cache/dalvik-cache
system
data
internal storage
and then wipe, after that go to wipe again, select cache, then "change partition format" select F2FS, and swipe to apply, do the same thing for data, don't do on dalvik-cache and system, or else this may brick your device.
Then flash the wt88047 firmware avaliable on LineageOS second or third post, do a full wipe again, install VoLTE universal Patch Here do a full wipe again, then flash the latest LineageOS build, after wipe only cache and data, flash OpenGapps pico arm android 7.1.1 and reboot.
You will have VoLTE
Try to flash RR 5.8.0 nought ROM. U will have voLTe working on ur device. I am currently using that ROM. Go for it

No... I didn't get VoLTE...

---------- Post added at 09:27 AM ---------- Previous post was at 09:24 AM ----------
If u want VoLTE u will have to flash the redmi 2 prime rom either fastboot or recovery...
However ur device will start lagging and ur free ram won't go higher than 300 MB.

voLte is working for sim1. See the screenshot below
Volte works just flash latest wxcpro ROM by editing its script so that it won't say 'this ROM is for so and so ****'

Took me time to try this...but didnt work.....you might think that i didnt follow the steps properly..but i did and i verified on each step that i was doing it the right way....but sadly it didnt work
You may try Redmi 2 Prime ROM (stable or dev) for some days..Check whether you get VoLTE on that ROM or not.. If yes then use that for some days maybe 2 or 3 days..It will be slow at first then after 2 to 3 hours of use u will feel no lag..I was using Developer version for 2-3 months which was fine for daily driver..I just faced storage issue..Then I tried stable version, and the same issue was there.. So I decided to use some custom ROMs and I Flashed AOSP Extended (Nougat)..VoLTE works fine and the ROM is so much smooth with good battery backup..But due to slow internet speed I am using Mokee 7.1 right now.. You can try using R2P ROM for some days...If VoLTE works there then it will work on other ROMs too( as per my experience).
Ignore my english...

Yes just flash either the dev or stable Redmi 2 Prime ROM. I can say that this works because I have flashed it on as many as three devices. Just go to this link and find out Redmi 2 Prime Global Developer ROM or Global Stable ROM.
http://en.miui.com/a-234.html
Remember these are to be flashed in fastboot. After flashing this, you can flash any Nougat based ROM like LOS, RR, AEX, cRDroid, etc to enjoy VoLTE on those ROMs too.

1)download Mi flash tool
http://en.miui.com/forum.php?mod=attachment&aid=NzYzMjQzfGFlZDEyMDMzfDE0NzI1NDg5MDJ8ODE5MTF8MzM2MTg0
2)
download fastboot rom redmi 2 prime global stable or china
http://bigota.d.miui.com/V8.1.3.0.L...DI_20161230.0000.00_5.1_global_23ac47dab8.tgz
above is global stable link.
3) put your phone in fastboot mode, unzip the downloaded rom. (avoid spaces in between folder path/name eg "C:\New Folder\Extracted rom\...." is not allowed instead it should be like C:\New_Folder\Extracted_rom\.......)
4) open mi flashing tool see if your device is listed. refresh to see. select clean all (flash_all.bat) option from bottom of mi flashing tool.
5) click on flash, and let it boot.
you would be able to use VoLTE now in miui rom. if you want to change to any N based roms just flash twrp and clean install any rom.
Flashing the MIUI 7.5.2 global ROM should work. Wipe everything and do a clean install. Once you see an indication of VOLTE on the MIUI then you should be able to get the same in other ROMS. I just did it recently.
Flash the redmi 2 prime rom using any of the methods fast boot or normal. If VoLte is what u r looking for

I think i can help you dude. Flash this fastboot rom you have. Boot it with YOUR Jio sim in the first sim slot inside. Setup everything normally in the phone. After it booted, you WILL see the Volte symbol in the statusbar.
Now root it and install TWRP. Now install a Volte rom of your choice. It has to work.
I will say you why this has to work. I own this device. The 8GB variant. My friend owns the same device. While my device had Volte working, his' didn't work. I checked it. He had kitkat bootloader. Then i flashed the lollipop stock rom in his device in fastboot mode. i directly rooted the device and installed cm14.1 in his device. Still no Volte. I wondered what the fcuk was just happening. My friend was like i'll cope up with this dude. I'll use jio 4g voice. But couldn't leave it like that. I tried it the second time just like i have told you and then VOLTE STARTED ****ING WORKING MAN !!! I was on cloudnine !!! Just helping you out !!
I think the reason Volte was not working is because the jio sim needed the stock rom to trigger it to start Volte sevices. Before it, the jio must have thought "yeah, this is a non volte device ". Just saying !!
Have a nice day !!!

I think their is no(simple) way to know that.But you can try a app named "phone info". But it didn't work out for me.It is showing unknown bootloader.
The best way to know your bootloader version is " try to remember which miui ROM u flashed last".
Or there is lolypop firmware in lineage is thread for u.

Simple. Press vol down and power. will boot into fastboot mode.
If the letters saying FASTBOOT are in green color and small, it is in KitKat bootloader. If the letters saying FASTBOOT are in Blue color and little big, it is Lollipop. I know it sounds a little lame, but trust me, this is a reliable method. If you flashed the lollipop rom via the mi Flash application through system, and youve got the blue colored bootloader, then you are on lollipop bootloader

1.MIUI fastboot ROM this http://bigota.d.miui.com/6.11.3/ken...1103.0000.00_6.0_global_f7309f8161.tgz (comes in *.tgz or *.tar not in .zip)
2.Xiaomi Mi Flash tool-BETA version.
3.ZCX TWRP.
4.CM14 CM14-firmware_20161115.zip from here https://www.androidfilehost.com/?fid=385035244224398629

7.voLTE patch from here https://www.androidfilehost.com/?fid=817550096634741250
nothing else
Q.Why fastboot ROM?
A.because it formats all the partitions also your internal storage (Take a backup 1st )and re-partitions all files on correct address. And this ROM uses the firmware that is mostly used on custom ROMs as I guess. I don't know I'm correct but that is what I think.
Q.Why NitrogenOS?
A.comes with less camera bug. Overall performance is good, can run substratum theme engine.
Q.Why voLTE patch?
A.it works on all voLTE or non-voLTE declared cm14.1 ROM. May be you will find your voLTE working without flashing it.
Q.Why ZCX recovery?
A.it backups all partition and have all the features of other RN3 supported recoveries(cofface,alka,official etc.)
Q.why cm14_15112016_firmware?
A.since it may lock your bootloader again but works great give a thanks to the developer of it.It is must to use this firmware for any force stop issue.
Q.Why RADON KERNEL
A.comes with stability and improves battery and performance get it here https://forum.xda-developers.com/redmi-note-3/development/kernel-t3414884
Follow these steps carefully and have patience!
Step 1
Flash the MIUI fastboot ROM v6.11.3through PC by using MiFlashTool using clean all option.
Step 2
after flashing, It takes too much time to setup your MIUI. recommended to use internet.
Step 3
now you find voLTE icon on this MIUI ROM.
Step 4
reboot to bootloader and check whether your bootloader is locked again or not. If locked, unlock again using official method.
Step 5
flash ZCX TWRP.
Step 6
reboot to ZCX. And take a backup of only these partition efs, firmware on your internel or in PenDrive(recommended).
Step 7
Make a folder like this "MIUI 6 efs" on PC and Copy the TWRP(/TWRP/backups/...) backup folder in PC from PD.
Step 8
Now copy these tools in PD CM14 firmware15112016, NitrogenOS, gapps, VoLTE_v2N_13-1-17.zip in PD and connect to RN3.
Step 9
Format system,data,Dalvik/ART cache,cache.
Step 10
choose install and flash the CM14_151112016_firmaware. It may lock your bootloader again. To check, reboot to bootloader from recovery and check by using fastboot oem device-info command on PC. If locked unlock again through official method.
Step 11
Now reboot to ZCX from fastboot. By pressing volume up button 1st and then power button when get a vibrate feedback leave power button(not volume up) untill the recovery window get shown.
Step 12
Now install NitrogenOS, install fpc_fix.zip(if you are using fpc fingerprint sensor,mine is fpc sensor so i flash it everytime), install Gapps and then restore the EFS backup you have taken(on MIUI6.11. blah blah).
Step 13
reboot to system and setup
If you find HD icon on status bar then good use it now or reboot to recovery and install
VoLTE_v2N_13-1-17.zip. now reboot you will definitely get that. If not then restore again the EFS partition.
You will surely get. If everything get done take a full backup of this ROM for future this ROM's EFS partition gonna work for you in future.
I'm SURE you will be stuck on this ROM
Everything is here latest android, Vulkan API, better battery backup and voice over LTE
Final
If it helps then thanks me and specially thanks to Sudeep Duhoon(https://forum.xda-developers.com/member.php?u=4913907) for voLTE patch.
--to XIAOMI for giving the permission to you for unlocking youe bootloader.
--to all others.

Help..Lost volte support

I lost volte support after flashing rr. N rom please help me I don't have PC to flash fastboot rom .

Someone recently told you have to flash stock ROM to get VOLTE again, that's not true (completely).
Truth is, you just need to boot stock ROM (only if you lost volte support while flashing custom ROMs, it will not work if your modem is defected.)
For, without PC,
Restore stock backup if you have,
Otherwise flash jerome's modified ROM.
Boot it, you will have VOLTE back. (Sometimes volte comes back on first boot or reboot will make it.)
I have lost VOLTE many times while testing OreO ROMs, and got back by restoring STOCK TWRP backup...
I am unable to get volte even after restoring and flashing jeromies rom .. Can you please tell me any other way to get it back.

Sim Signal problem lineage 15.1 unofficial

I have note 3 sm-n9005 htle running os lineage 15.1 that made by @haggertk
I have been using lineage 14.1 unofficial made by trader418 and haggertk for months everything was working fine i didn't have any problem then week ago i saw lineage 15.1 so i clean flashed my phone to lineage 15.1 at first everything was working fine then after a few minutes i restarted my phone and then my phone stopped receiving signal
I restarted a few more time times and suddenly signals came back
But then a few hours later same thing happened again
Now every time i restart my phone or battery dies i have to restart my phone serval time till signal comes back
Today i realized every time my phone stops receiving signal phone app (dialler app) crashes when i dial *#06# and auto network registration automatically turns off when i turn it back on it says can't connect to thins network now please try again later. Or when i try to choose my network manually it says error while searching for networks
After a few restarts everything just works fine everything goes back to normal
I've already changed CP and BL serval times to serval different (CP and BL)s it didn't work
Anyone else has this issue?
Or please anyone knows how to fix it?
I'd the same problem with you before. I tried to flash new modem and bootloader (in LOS) but it didn't change. So, this what I did (it quite long but I hit jackpot after that)
1. Download Phronesis Rom (it is custom stock rom, maybe can use another custom stock rom) and put in the internal storage
2. flash TWRP2.8.70
3. you can see instruction on how to flash Phronesis
4. Reboot system
5. Enable Developer option (if it is disable)
6. Flash Bootloader (BL) and Modem (CP)
7. check it back using phone info app (for me, it did work)
8. reboot recovery, flash TWRP 3.2.1.1 again
9. Full wipe

I'd the same problem with you before. I tried to flash new modem and bootloader (in LOS) but it didn't change. So, this what I did (it quite long but I hit jackpot after that)
1. Download Phronesis Rom (it is custom stock rom, maybe can use another custom stock rom) and put in the internal storage
2. flash TWRP2.8.70
3. you can see instruction on how to flash Phronesis
4. Reboot system
5. Enable Developer option (if it is disable)
6. Flash Bootloader (BL) and Modem (CP)
7. check it back using phone info app (for me, it did work)
8. reboot recovery, flash TWRP 3.2.1.1 again
9. Full wipe
10. Flash LOS and gapps
11. reboot system

Why you need phronesis? Only for enabling developer options? Maybe you forgot the critical step of removing battery before entering to download mode to flash BL and CP in ODIN? Because you seem to use a custom ROM only for enabling developer options and checking phone info samsung app (both of which can be done in stock firmware or even LOS itself).
Because I need to flash the modem. I tried flash the modem using ODIN in LOS and RR (both with developer option) but unfortunately failed. That's why I going back to Phronesis, just to flash the modem

I have seen many users flash modem on LOS and RR using ODIN when steps are done correctly. The part confusing me on noth of your posts is you didnt try to check your modem after flashing in LOS (using settings/about or phone info samsung app)? Because if it shows it updated, then it is updated. If not, then you have missed a step. That simple. It cannot be that "it shows modem is updated but somehow it isnt".
I dont think any external step of flashing another custom ROM is necessary. Flashing modem step-by-step procedure is available in many posts of @svbarbosa and @Hereiwas.
I did check the modem after flashing every single time, I flashed with different modem and bootloader, unfortunately the result is same. After failed so many times, than I tried flash Phronesis as my last resort. And I really don't know and understand why my device like that (I follow exactly the procedure as given)

I never check it before but when I red your comment I tried changing baseband and bootloader and then I realized it always gives pass on Odin but it never did really change baseband or bootloader i think the problem is with the lineage 15.1 that makes baseband untouchable

I have flash LineageOS 15.1, i also have problem with signal and gsm,after that i flash CP and BL,it was the same.
i go back on stock Rom,download samsung Firmware and flash phone. now if I install Phronesis do i need again to flash CP and BL?
If you are already on stock rom, no need to flash phronesis.
Ok. But I want to install LineageOS, how to fix problem with Gsm network?
Updating BL and CL did not solve the problem. What should I do?

One more question: when I go back to stock rom i don't have root anymore but I have installed Twrp recovery. This phonesis rom is nice. I would like to flash my phone with this rom. Do I need root and does gsm network working without installing BL and CL?
I will install this rom from my phone without root from TWRP 3.1.1. Can I do that?
I have the same damn problem!! LineageOS is sooo buggy with SIM mobile signal connection... it just kills it!!! How the hell can I fix this? Where can I get the modem files for Samsung 900V?
Please read thread and see your identical post .
Suggest you stick with stock rom or try your models forum.
