Can i install full oreo as hardbrick device ,or i still get the chance??
Your device is not hard bricked, given you can still boot.
You can install Oreo via fastboot, though I would advise a clean flash given we don't fully know what happened to your device. Alternatively, download the TWRP flashable and flash that via TWRP; what TWRP are you using?
Also (thanks to strongst), you didn't mention what IMEI is being reported: can you please check System>about phone or settings>about phone (or similar settings), then report your baseband as it is in the Pie ROM. Also, tap on status and then IMEI information. What IMEI are being reported?
Do you still see loss of IMEI with mini GApps?
Once again, please be patient. This is not a real time forum and I understand you're desperate for help. We're trying to understand your situation and what you've done, so we can best help you.

I use lyuu's twrp recovery with efs and in settings my imei show unknown.for baseband I will answer you later.
If your IMEI is truly shown as unknown, you should read this guide https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-imei0-issue-t3859068
Having a quick look at that guide, looks like it covers that scenario too. Give it a try.
Problem is solved ,I flash twrp Oreo file and revert to Oreo ,but after 1 hour again my sound is very low as before.
Problem is not permanent solve but I have question.
1) I take backup but can't restore it , this happens with me twice.
2) if I have error in restore ,I understand but I take full backup and when I restore it I shown message that you successfully restore 7 partition with no red text error. I temporary flash Oreo stock ,but it will happens with other guys also. I restore backup and stuck in recovery .
If there fail all time so backup is not necessary if it will be can't restore. @echo92 and @strongst thank you for helping me out.
I happy with stock Oreo but with low speaker sound ,so I went in pie and my problem is solved ,so I revert back to Oreo and stuck.

Okay, so what's your question?
Try using another TWRP to back up and restore, see if that gives you the same issue: https://forum.xda-developers.com/mo...recovery-twrp-3-2-1-unofficial-touch-t3722206 which partitions are you selecting for backup and restore?
I not know very much about backup ,so I tick all the available options (like system, system.img ,data (exclude media),efs )) etc...
I don't think you need to back up system.img unless you're going for an OTA compatible backup. Backing up system (without system.img) should be enough.
Try just backing up system, data, boot (and EFS or OEM), then try restoring. Normally, system, data and boot - boot as in kernel - are enough for a backup - recently, issues with modem between stock and custom firmwares made backing up EFS handy. OEM partition is up to you, that shouldn't change unless you've been debloating your device.

Here's an explanation from the TWRP maintainers: https://twrp.me/faq/whattobackup.html
System.img is useful for OTA update (but only if you did not swipe to allow modifications), else system is sufficent. System.img will vary with ROM since it's a system partition backup.
Ok I went through link that you send me ,in that thread they trying to tell that make backup of system.img because of some dm security ,I don't understand technical word ,so I can not understand full thread.
Now system .img you said is preferred for OTA update ,so if i don't restore so I will not receive OTA update??
Furthermore there is EFS backup ,it backup imei and baseband I think ,if I restore all partition except efs and if there is imei =unknown or 0 ,so if I restore only efs after first time restore(without efs restore),it is sufficient or not??
