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.

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

No... I didn't get VoLTE...
I am using the same ROM.
---------- 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 ****'

How can that screenshot say that VoLTE is working??? I can't see any HD or VoLTE sign..
U can see there enhanced 4g LTE mode which means volte.

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).

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

I had that problem too when flashing the non-treble version. I'm not sure if this was your issue, but I had to boot back into TWRP and change slots in the reboot menu. Then it booted. So next time, you might give that a shot.
There is a step missing in the instructions too. There is no instruction on when to flash the gapps. Flashing them *after* Magisk worked for me.
If audio quality matters to you, I haven't found a custom ROM that sounds as good as stock, so I'm back on the stock ROM, even though I really liked RR.

IMEI problem on october patch oreo rom (stock moto)

Hey guys, I tried flashing the stock moto oreo rom (october patch) through 1. flashing via fastboot and 2. twrp flashable rom.
Both methods worked but I lost my IMEI, regardless of which method I flashed the rom with.
I had made two EFS & Persist backups (one from resurrection remix rom and one from a twrp nougat june patch rom) and tried to restore them after flashing the moto oreo rom, but no success.
Can anyone help me with this? I really want to use the stock oreo rom!
Please help guys!

Try flashing one of the full flashable zips from that thread, get the last one. But in the installer, do not select firmware.
Hopefully that will get you going again. And no, don't ever install an ota.

Thanks for all your help is there any way to fix OTA updates? like relocking bootloader? or should I just leave that unlocked ?
I just installed \POTTER_NPNS25.137-93-4_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
and am getting a 3g \ H signal now but its a different sim card and service from original card, seems to be working now
Is it just oreo that screws everything up , I know this is all over but its not very straight forward
im no android expert clearly

Bootloader doesn't matter, can stay unlocked.
And the IMEI/4g problem is Nougat only, never heard of someone who lost something on Oreo or when updating to it.
If you flash latest Oreo firmware for your region (endings with 17-xx are US, 13-xx is for the rest as far as I know) you should be good to go.

you can install the February update then reboot your cellphone if it works, congratulations on your efforts. if that case still continues you can reset your network card from setting the signal reset, bluetooth and wifi, and then reboot ... and enjoy your repair effort If it's not sweet enough, you can reset your phone's factory and reboot. enjoy it

No network signal despite EFS and persist backup. Only have the IMEI numbers.

I was using Bootleggers (8.1 Oreo ) ROM on my XT1686 and tried flashing Pixel experience (9.0 pie ).
Steps i went through:
1. Clean Wipe
2. Flashing Pixel Experience
3. Losing my network signals and IMEI
4. TWRP flashable 8.1 stock rom
5. Flashing the bootleggers 9.0pie update
6. Trying the erasemodemst 1/2 commands. NO result.
6. Restoring EFS and persist from the previous backup.
7. Ended up having IMEI back but still no network signals after multiple reboots.
I do know that flashing a STOCK ROM using fastboot and performing a clean reset will get my network back but will i have to stay back in the STOCK ROM ? Can nothing be done that allows me to keep using this amazing rom with a functioning network ?
TL;DR: NO NETWORK, IMEI AVAILABLE. EFS AND PERSIST BACKUPS ARE FLASHED ALREADY.

You didn't say from what ROM/firmware the persist.img backup was taken. If it wasn't from your original stock firmware that may be a problem. If it was from stock which version, 7.0 or 8.1?
If you flash a 8.1 signed fastboot firmware you should be able to change to every ROM you want to afterwards.

I lost the IMEI and VoLTE when i switched from 7.0 (stock) to 8.1 (experience ) rom and then had to use the VoLTE fix to set it straight.
After i got everything working in my 8.1 pixel experience ROM , i made a backup of all the partitions. I used that backup here.

Most probably the problem was to switch from 7.0 stock to a custom ROM, you should have updated to stock 8.1 and make a backup of persist before doing that. The persist.img will be modified when flashing a custom ROM.
If you haven't flashed someone else's persist file the best way to go would be flashing a signed Motorola 8.1 firmware by fastboot, take a full nandroid incl. persist and go from there to a custom ROM.
Here's how to do it and links to all available firmwares:

Thanks alot @Wolfcity. Sorry i couldnt reply sooner. I flashed a twpr flashable 8.0 stock by @NZpred from the page here:
https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-fastboot-flash-stock-oreo-t3848433
It brought back the signals. After that i backed up all the files and EFS and reflashed the custom rom and the EFS and persist.
Thanks alot for your help and timely response.
