I have rooted my asus zenfone max (Snapdragon 610 Model) . And have used both custom roms and as well as stock rom.
Issue is when i factory reset stock rom or reflash original firmware Volte is not showing up.
Luckily i had a nandroid backup of stock rom which when restored volte worked.
Can any tell me what could be the possible reason and solution for rectify this glitch.
TIA

I don't even have any backup and so the volte is completely gone from my phone. Have installed all versions of firmware, downgraded and upgraded etc etc but still no help. Someone please tell me what to do to get the volte back without rooting.

Hi, i was on official leaked lollipop Chinese rom, until Russian official lollipop released.
After wipe and format all thing with twrp and flash 8gb pit file and flash Russian official rom there was a lot of problem, device was so laggy and when it went to lock screen and display turned off, there wasn't any way to turn it on except remove battery and put it again.
So after that, i flashed leaked Chinese rom again and all problems gone.
Now Indian lollipop released and i flashed it and all problems come again.
What is the problem? and how i can solve that?
anyone??
I'm having the exact same problem.
I was having difficulties installing custom ROMs and decided to go back to stock and try again... Now I can't install anything properly.
@Mohamadreza - Have you had any joy?
I take it you've given up?
I tried flashing both stock K and L roms without any joy. Eventually found an old backup. Restored that and now is is back to normal.
Hope your phone is alive again...

Well it is expected to give a Factory Data Reset after flashing the Firmware through Odin.
Flash the firmware and give a factory wipe from the stock recovery.
I hope it will solve your problem.(mine was solved)
All the best!
I found solution .
The solution is downgrade to kitkat rom and then upgrade to any rom you want like official lollipop
I tried flashing both official KitKat and official Lollipop roms without success. Restoring fixed my problem.
Glad you're sorted now.

Hi, My cell is on LP 5 but i don't like it, can i isntall any kitkat rom without flashing the kk firmware, if yes how
thx
I think that yes. I flashed on my G900F Miui based in KK and it worked on LP firmware
Lollipop Update Blocked downgrading.
It's not going to work. I think that using a nandroid backup made by somebody else should work.
After i rooted my N910C, i didn't backup my rooted stock rom. However right now i'm on the latest 6.0.1 Bliss rom, and want to revert back to stock rom because of several issues i have.
The problem here is that I do not have a backup of my EFS/IMEI from the stock rom. My IMEI is still working on my custom rom, can i make a back-up of that and will it work?
And do i need a back-up at all for reverting back to stock from the 6.0.1 Bliss rom?
Better give it to the Samsung authorized service centre and reflash the stock ROM (you will be charged).
Yes, you can back it up and it will work should you need it.
It is not normally required. Going backwards and forwards between ROMs doesn't generally cause any problems, but it is advisable to create a backup just in case something goes wrong.

I managed to fix this problem but not on stock rom.
I had the same issue, i flashed Pixelexperience and found that imei were back.
Problem is only on stock rom.
And if you are not getting 4g on Pixelexperience go ahead and flash the modem files
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2

Volte isn't going to work anymore. Switch to airtel.
I found another temporal solution to get back the imei in stock rom.
Wee need:
- TWRP 3.2.1
- This flashable stock rom: http://www.mediafire.com/file/79spjgvj7eklr4g/potter_NPNS25.137-15-11_sdat4.zip
steps:
- Flash a custom 8.1 rom(i tested with Pixel Experience).
- Backup the EFS file*
- Wipe Davilk, System, Data, Cache.
- Flash flashable stock rom with TWRP.
- Restore the EFS file.
- Reboot and we got back the imei.
* Note that first we need to start the flashed Pixel Experience Rom(and get signal i think too), restart recovery and then make the backup of the EFS file, cause i made the backup without starting, flashed the stock and restored the EFS file, imei was not.
UPDATE: You also can do it with any stock rom. In this form you only need to flash the twrp and restore the EFS file or flash the rom via fastboot, flash twrp and restore the EFS file.

Build No. Of Stock ROM you flashed?
I made a quick guide to obtain IMEI and 4g again, even on stock rom with bootloader relocked. This worked for me, just give it a try.
https://forum.xda-developers.com/g5-plus/help/restore-imei-0-moto-g5-xt1687-t3739808
here is a working solution but if u flash stock rom again u will loose the imei and network again so i recommend staying on any android 8.1 rom for now but atleast u will have imei and network back dont use his download files because they are for the cedric G5 try find the exct files but for the G5 plus they should be on the g5 plus development section of this xda site
I tried to installbpixel experience rom but twrp error 225
