Please note, this is not my work and I do not take credit for it as such. I am merely providing these useful links to help others with active development. I myself do own this device however, and I will be happy to assist others as much as I can, and as often as I can.
Root; follow the instructions found here.

TWRP (Use root rashr, or flashify to install as recovery.)

1. Grab the following files from this Zv5 backup. https://mega.co.nz/#F!DMVWTQKa!QTYe1H-nMI4gBoPlIz7VpA
boot.emmc.win
boot.emmc.win.md5
data.ext4.win
data.ext4.win.md5
data (info)
system.ext4.win
system.ext4.win.md5
system (info)
recovery (log)
(Note, DO NOT flash any files that were not listed, you will ruin your service.)
2. Place them in a folder named anything you like. (No spaces or special charactures.) And place the folder inside the twrp backup folder on your device. See attachment for an image of the folder structure.
3. Reboot into recovery. Wipe data, cache, and system. Then flash the backup provided in step 1. (If you cannot see the backup, verify the folder structure.)
4. Reboot the system, verify the phone boots properly and has your phone number in the about phone section of settings, and also verify that you have Zv5 under software in the same neighborhood.
5. Reboot back to recovery, then wipe data, and flash ONLY your data partition from your Zv4 backup. Reboot, and you should now have 3g/4g working again. Make a backup, debloat again if you wish. Done!
*This may work without flashing the data partition from your Zv4 backup, however I cannot confirm this. 3G/4G does not seem to work without flashing the Zv4 data partition, though manually updating the prl might get around this. If anyone would like to try, please post the results.
Root disclaimer, I am not responsible for any bricks, loss of service, bugs, glitches or anything else you choose to do to your device. Proceed at your own risk, as always, make a backup.
***Special notes regarding OTA updates. It is highly recommended that you allow your phone to completely update before installing TWRP and BEFORE REMOVING ANY SYSTEM APPS! If you are not on Zv5 you can encounter a recovery bootloop if you try to take the OTA update. If you have already debloated and are on Zv4 it is still possible to update to Zv5 if you already have a TWRP backup. This may also work without a backup, testing is needed however. See below for instructions.***
