What do you mean Indian Verizon ?
Why did you flashed Verizon version, instead of this you could have done fastboot XT 1550 6.0 or 6.0.1 Indian version factory firmware and rooted.

I read his reply many times and now I understand, he was saying 'version'. If you do a typo verison instead of version, the autocorrect maybe is replacing it with verizon (I don't use auto correction).

Is this stock rom with VOLTE support is rooted ?
What are the steps to be followed before flashing this rom?
How can i back up all data and app?
If this back can be used to restore every app with data after flashing this stock ?
Please help me

Hi,
if you are currently on Any CustomROM, and want to flash back to Stock 6.0.1 !!
please use the Guides, of a guy named -LOST
you cannot Flash the ZIP as customRoms, you need to have PC inorder to follow those steps,
what i do before changing ROMS:
install TitaniumBackup, and apply Filter ( user apps+data) , then Backup all those to my SD CARD, then after changing ROM i would again install TITANIUM BACKUP app, and RESTORE by setting location - SD CARD.
NOTE: please format your memory card to PORTABLE, if your memorycard is now as INTERNAL.
if you have so many doubts, there is whatsapp group for IndianUsers. give your PHNO: i will say them to add you.. there are so many people who can help you there :highfive:

If you on pure stock ROM you can root using root guide posted in device forum and the one which you mentioned stock ROM is " optimized " version of stock ROM which is rooted but it doesn't support VoLte.

Hi, Thanks bro..
Here are my current situations..
I have tried rooting using Moto tool, found in this forum. But it was disconnecting frequently and failed to root. Then read through this forum and successfully unlocked the boot loader,installed TWRP and finally tried to flash super su.May be due to the incompatibility of files i have used, my moto g 3 went to boot loop..
Searched through this forum and found STOCK_6.0.1_optimized_MOTOG3_Ver1.0.zip and installed it using TWRP and now My moto g 3 is booted successfully and rooted. i have used jio 4Gvoice app for calling two days.Today,after i cleared cache using TWRP, VOLTE flag flashed up on notification bar , the app not able to make call,instead it re direct to dialer,not able to make call.
I am a beginner in rooting,and want to stick with stock rom now. So i searched for the Stock Rom with VOLTE support and found this thread.
So my Question is XT1550_OSPREY_RETASIA_DS_2GB_6.0.1_MPI24.107-55_cid7_subsidy-DEFAULT_CFC.xml.zip mentioned in this thread supports VOLTE or Not,also rooted and optimized one?
If yes, these are the steps i would follow to flash this Stock rom.
1) Back up all user app and data using titanium backup to my sd card
2) Put stock rom XT1550_OSPREY_RETASIA_DS_2GB_6.0.1_MPI24.107-55_cid7_subsidy-DEFAULT_CFC.xml.zip in SD card
3) Install the above zip using TWRP and clear cache
4) Restore data from Titanium back up.
Could you please check and validate these are correct or not

bro..
you should not flash with TWRP,
those files are having seperate process, and MOTO UTILITY isnt Good at ROOTING, it can push ROOT file for you in to Internal storage, but it wont Root..
1) i am using STOCK, (the zip you mentioned above), i installed TWRP, then i ROOTED, then INSTALLED xposed also..
2) Volte on JIO works fine even after doing all these things..
3) to install the STOCK ZIP , you must have a PC, dont use MOTO utility, because it has a CHUNK FILE missing..
for the process of installing STOCK..
you must UNZIP the full ZIP folder in to ADB+ FASTboot folder ( this is the first thing you must do )
that should look like this : View attachment 3918160
then follow the process
http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750
please dont use UTILITIES, and make sure you backup all and lookout for SD card formatted as external/portable. :highfive:

Fix for VOLTE Marshmallow MIUI

Last night one of my friend told me about this. So i tried and found it working. All credits to him for discovering this, i am just sharing.
HIS MIUI TOPIC IS HERE Go and support him.
He has posted fastboot method there that is a bit simpler, use that if you like. Here i have posted recovery flash-able zip.
Things required:
1. Redmi note 3 with bootloader unlock and TWRP recovery
2. Any Marshmallow MIUI rom
3. Firmware zip
Steps:
1. Unlock bootloader officially/unofficially and flash twrp by fastboot.
2. Download the firmware zip and rom and place them in internal/external sd.
3. Flash the firmware zip first and then the rom.
4. Reboot.

Put your phone in fastboot mode, then connect your device and Run Flash.bat
BTW: As per the original posted: This will work on MIUI ROMS tested in Beta MM version, EPIC MM and Ported MM from Kate, and I guess this should work on AOSP roms since the modem files are from AOSP base, this fix won't work with CM13 ROMS since the base is different and we are working on it to fix, so stay tuned!!

Is this working with slim aosp based rom

Not working for me...
I flashed firmware.zip then rom and then lazyflasher zip to decrypt boot.img without wiping anything

This will not work. Firmware files aren't same from original zip files in MIUI Forum thread and as you can see, only needed to flash Modem + DSP file and not entire firmware-update folder. To get this fix working you need 5.1.1 Modem and my modded adspso.bin. Raaj52 said that this files are from 6.0 AOSP but if you look into new replies, he said this is 5.1.1 modem and I modded adspso.bin file to get working 5.1.1 Modem in 6.0.1 without fluence and video recording issues.

Best firmware for Kenzo is v7.1.12....it ve better network connectivity than other firmware.

Please update the link of latest firmware, it's removed.

I have removed the link of latest firmware as it is not better than older one.
So its advisable to use 7.1.12 firmware.

Why you want to downgrade? I ask you because i want to upgrade my phone to 7.1.

can i do the same on my Oreo 8.0.0 based on AOSP

I updated from KitKat to Nougat(RR 7.1.2 by devharsh) and I am not experiencing any issues.
If you are still on KitKat...I say go for it.

I did that once, because I thought that banking apps were easier to use on a phone, but old android is just soooo bad, I just couldn't stand it.
I tried running 4.4 for a while, but every time there was no signal, it just shut down. I tried upgrading to official 5.*, and it became extremely laggy. Tried different versions, but nothing worked better.
You can try it, but I don't recommend going back if you are already using 7.1 for a while, because you just get so much used to all of the functions.
If you want to try, first you have to get stock recovery because stock rom won't run from trwp.
I did it with the flashing utility, where you have to connect your phone and make it go to service mode.

As MclBenner said, you need to update your TWRP : https://twrp.me/leeco/leecolepro3.html

Try redownload and copy the rom again to your internal memory. That may help

i was also getting error 7 when trying flash rom's as well.
I tried updating TWRP as instructed above and continued to get twrp error 7 when i tried to flash any rom.
I then noticed that my error was based on the modem baseband date being wrong.
So I just re-ran the 20s update via eui's update utility and rebooted and was able to flash rom's again.
I hope that helps somebody.
I don't believe the problem was the TWRP version because I re-flashed it twice and the error 7 persisted

I had to flash the 20s firmware from codeworks thread in my case the error 7 was because I had the wrong modem date installed.

Maybe you can restore that backup from twrp. I've used it before

I'm not sure but I just flashed a custom ROM over that backup and everything just worked for me.
I never tried to use it so I don't know. Maybe you have some leftover stuff that you didn't get wiped.
I'd try to start over now that you have the ability to flash ROM's again.

Respectfully, there is no 21s firmware, go back one page and read.
This error 7 is the most common issue on the Le Pro 3 forums and the question has been answered literally a thousand times.
Error 7 is resolved by updating Twrp.
If you cant update Twrp, update your firmware.
Do a Google search and type : "All in One Tool Leeco Pro 3"
You can use it to resolve all of the possible issue variables, so download the newest version of Twrp for your device.
If you have a ZL1 then download the Twrp for the ZL1 if you have a ZL0 then download the TWRP for the ZL0 : I suspect that this is your actual issue: wrong Twrp.
Again get your files together: Twrp, Rom, Gapps, Magisk and at your current stage of using Roms the All in One tool is the best and easiest option. The All in One Instructions are on the Main All In One Tool XDA page.
Sim Card Card issues are often resolved after flashing the correct firmware.
