Did you flash the community build that oneplus offers? Not. 3.1.2 but 3.5.2? it bricks booting / flashing into twrp and therefore flashing anything else. Sideloading doesn't work on that either.
Flash the TWRP recovery attached to the first post of that thread. Then you should be able to boot into twrp and flash another rom to get your phone back to life.

Did you Find solution for this problem? My friend also has this problem, after unbrick.
Can you tell what you did before you brick your phone first time and all steps after?

Look around on the forums. There are 3 versions of TWRP for this phone in the ROMs, Kernels, and other development section.

[SUSPEND] VOLTE fix for those who had lost after flashing stock(DON'T FOLLOW THIS)

EDIT
I HAVE DELETE THIS THREAD BECAUSE BY USING THIS METHOD PEOPLE MAY LOOSE THEIR IMEI if they don't have any efs backup ,
People apply this METHOD who has no IMEI Surely this method was only for those who already had efs backup ,
but now people thinks that it may bring IMEI,,which is not the proper way for restoring imei.
So to stop this misconception i am deleting all files and SUSPEND this thread.

Members wishing to try this are advised to take extreme caution. This Thread may explain: HERE

MAY BE YES,YOU CAN,BUT TAKE BACKUP OF ALL PARTITION BEFORE TRY.
this persist backup is from moto g4 plus and it is working for moto g5 plus so may be it should work for g5s plus too.
but remember i am not responsible for anything if it goes wrong( but it better to take risk when nothing works )
my gut says,it should work,so if you want ,then give it a shot.

ok will try that in the evening

Which ROM have you tried? Its not working in DotOS. Please help!

akshu2697 said:
hey guys good news for you all,
i have found the solution for volte.
download persist backup from attachment(this backup is from moto g4 plus,i had restore it on my moto g5 plus and i got volte )
1)Flash stock rom with twrp or with fastboot,both will going to work.
2)Now you have to put this backup in twrp backup folder.
3)after this first you have to restore your own efs backup.
4)then restore this persist backup.
remember"do at your own risk",i am not responsible for anything if it goes wrong
this method is working for me so i am telling you all,and before do this please take your whole phone backup including every partition.
this can also be done if some one can provide our moto g5 plus persist backup,so if anyone has working volte then provide us moto g5 plus persist backup from twrp,then it is also usefull for all of us,THANK YOU

Unzip that persist file,
Put that file in your efs backup folder ,
After boot in twrp and go to restore,
Then in restore restore your efs ,you will see persist will also there ,so restore that persist after restoring efs.
In other words ,
#Unzip persist
#Open your efs backup folder of twrp in file manager
#Paste persist file in efs backup folder
#now boot in to twrp
#restore that efs ,in efs you will see efs and persist both will be there,
#so first restore efs then persist
See my attachment (how to put that file in twrp)

can someone please give a step by step guide of this method. I haven't tried anything like this so pls help me. I am on stock rom and bootloader locked. I really want to get my volte.

Just need help as I am new to zuk z2

Hi.. I am a noob but I am a pro in Mi4 ( cancro) but this time It has locked bootloader and I got unlocked img from zuk developer website is about 512 byte and two users comment in the bootloder unlocking and twrp recovery section they are facing issue and actually unlocked boot img file should have 1kb but I am confused and another q can I flash terble compatable twrp at once and regarding rom installation also which partition to be earsed ( efs) and which not to and baseband update section I got it and rom installation I got but after baseband update I have to restore Efs???

And what is the size of unlocked boot img you guys got

Which zui you do have? Probably nougat one, so ur baseband should be 1.70, if its then there is no need to flash baseband.
Don't know about size on unlock img but you should go ahead and see ifs its getting any error then share here.

Ok

One more thing baseband for oreo is needed

I want to flash aex oreo

And what is that efs

First flash official twrp then according to your need and read full post carefully of the rom you are going to install.
There are several twrp and vendor to factory and vice versa zips, some latest build of roms need these zips to be flashed first and some don't required treble twrp so first read instructions carefully,

Ya I did but I have misconception with baseband

Can you msg me in whtsapp 9853687062

Bro plz msg me

If your baseband is 1.70 you don't need to flash baseband

I F*cked up! Help me please?

Long story short bought a G5 Cedric running latest official firmware oreo 8.1, didn't like it cuz it's too heavy, unlocked the bootloader, flashed twrp then flashed lineage 17 but can't pass safetynet,(clean) flashed resurrection remix after same problem, then i flashed omni rom and suddenly my IMEI was gone and can't install gapps, what to do now? I just want a good custom rom that passes safetynet, don't care if it's pie or Q.

Flash a rom where imei works
Backup efs partition using 64bit twrp
You can then restore efs partition if you loose imei
With regards to safetynet none of the custom roms will pass without you doing some work
You need to flash magisk
Flash Busybox magisk module
Flash props config module and follow all the instructions on how to change device fingerprint eg to a pixel 4 https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228/
Hide magisk manager with a random package name from magisk settings
Hide app that detects root with magisk hide from its settings
You can also try the universal safetynet patcher magisk module if the above doesn't work but some report it causes bootloops on some devices/roms

Thank you for the quick response, i have a few questions regarding what you said:
1- how will i know which rom to flash where the IMEI works before flashing the actual rom itself?
2- how do i know if my current twrp is 64bit or not? it's the one from the Lineage 17 thread.
3- when im succesfull in executing those steps and i have to back up efs, where can i find it to restore it if i flash another rom again? because last time before flahsing i wiped system,dalvik & Cache & data but not the storage and yet my back-up was gone?

1 - You will have to try roms yourself to find out
2 - All custom roms from oero onwards are 64bit - you wouldn't be able to flash them without a 64bit twrp so you already have one
3 - data/media/twrp/backups or storage/emulated/0/twrp/backups
I recommend changing the storage location to your sdcard so they don't get deleted when you wipe data or transferring to a pc
Formatting data is effectively formatting internal storage as the device is encrypted

If rebuilding the efs doesn't work I do not know
Backup efs first incase it fails to rebuild and imei is 0 again - use a twrp 64 bit to back it up and obviously save to sdcard & pc incase you need to re-flash rom as wiping data will erase your backup on internal storage

it didn't work as my IMEI was 0 on both sims, thankfully i backed up EFS before erasing, so I managed to restore the IMEI again.
Is there really no other way to get 4G back?

If it doesn't work in rom then move back to stock Oreo and once you got the 4g take backup of efs and persist and move to custom ROM. If the 4g is available then no need to restore backup, if not restore the backup and enjoy 4g.

I wouldn't re-lock it for several reasons
1- you need the unlock code to unlock it again & Motorola will say its already been unlocked
2 - Even if you re-lock it it will still display its been unlocked previously
3 - if you ever need to flash stock firmware via fastboot again it may fail with permission denied as the firmware may not be fully signed & you can't flash unsigned firmware with a locked bootloader
4 - if you ota update & it it fails & you hardbrick then again same as point 3
If you really want to Google how to & you need fully signed firmware else it will not lock

I'm going to respond to each point you mentioned:
1- I still have the email from Lenovo containing the unlock code, do i need the same code to relock the bootloader?
2-are you sure it will still say it's been unlocked before?
3-what does fully signed mean? i searched through the link you sent me earlier and i found the same one that i flashed through LMSA, that is XT1676_CEDRIC_RETEU_DS_8.1.0_OPP28.85-19-4-2_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip is the one I flashed through LMSA not fully signed?
4-there's no updates anymore after the version i mentioned in point 3.
side question: does this method you mentioned still applies to relock the bootloader without the aforementioned issues?
PS: it still says ID: bad key on the bootloader unlocked warning, even though i retrieved my IMEI number, shouldn't it display my IMEI number instead of bad key?

You don't need code to lock bootloader - just to unlock it
Yes the bootloader will display its locked but will also give a status code that states its been previously unlocked
Fully signed means each part of the firmware has been signed by Motorola - sometimes the boot.img isn't
You will always get bad key or n/a with an unlocked bootloader - this is normal - you can flash a modded logo.bin to replace this
Those are the steps to re-lock the boot-loader - obviously oreo firmware has more sparsechunk so add the extra parts
