Maybe you flashed the wrong version of persist then. Make sure you get persist.img from the original fastboot package that matches your current system.
There is a thread here about it, maybe reply there?
Unfortunately I'm waiting for a new LCD for my device, but I do plan to look into this deeper when that time comes.

Fingerprint keeps vibrating like if it detects something.

@strongst Saw this? What's happening? 40% of people having the same issue! While installing a new ROM their fingerprint scanner stops working. How's that possible? What's the cause? We have to address this issue.

Sorry but it's a hardware issue. 80% of members here got the same problem in the same période of time (fabrication issue)
Soon your home button will stop working too
Use nuclearom 1.1beta no issue with fingerprint
It's already discussed and a hardware issue cause there is no proof way to solve it with software. What's the real cause of this issue isn't known, but a faulty hardware piece is more sure then triggered by a rom update. How many people flash the same rom? Does everybodys fp reader stops working after flashing that rom? No!
its not hardware issue. you messed up downgrading or restoring a old version of lollipop. erase all partititions and flash stock via bootloader.

After flashing my oneplus 2 some issues with Car-Bluetooth and HW-keys

Hi guy's,
I didn't found really on the forums.
After flashing my oneplus 2 to JDCTeam_jdc_oneplus2-7.1.2-20170609-STABLE(STABLE7)-1 - Kernel 3.10.105-aosp I get some troubles with my car connection over Bluetooth.
Now after flashing I can't use my phone functionality.
The pairing is done well, but it is shown in settings from Bluetooth - the device couldn't use the phone functionality. I have tried many to fix them, but nothing works.
Any hints?
The second issue is that I can lock (pin) an app in the task overview, but unlock isn't possible with HW-keys. For unlocking I have to push and hold the task-overview and the back-end-keys, but instead release the locked app happens nothing. So I have to switch off my Mobil for unlocking.
Please let me know what I can do to fix this problem.

Okay. Do you mean that the another ROMs solve my issues?
... Yes of course nobody give a guarantee, but I hoped on guys the have the same issues like me and can tell me a solution inside my flashed version.
So far so good, I will consider about for another ROM, with hopes this is the only solution.

VoLTE gone forever?

To address the issue, a lot of people (including me) lost their phone signals because of IMEI turning to "0" after flashing some 8.1 based ROMs.
There were few tutorials to get back the signals but now no matter what ROMs I flash, VoLTE isn't there at all.
Custom ROMs have the option but the switch does nothing, stock ROM doesn't have the option at all (see screenshot below)
I'm curious if anyone faced a similar problem and managed to get VoLTE to work.
I am also one of them. It was something in the early January build that made it happen. Because I switched back and forth on Stock and custom ROMS on December 2017 builds and everything worked fine.
I am just waiting for and OTA or Oreo update to see if anything happens.

For me, I have the same issue; but I guess my IMEI # is intact because when I dial *#06#, it returns me with 2 IMEI numbers for both my sim cards. what might be the issue in this case?
I'm curious about this issue with VoLTE. What's causing it? Is it reversible with a backup restore? Is it hardware specific or software specific? Do we have any workaround for it?
The 8.1 ROMs might have overwritten some files related to VoLTE
volte
any one knows how to fix volte?
Mod Edit: Removed rude/disrespectful quote
Don't call anyone stupid FFS. We don't have a solid proof what exactly is causing it. Atleast they didn't do it intentionally.
---------- Post added at 10:36 AM ---------- Previous post was at 10:34 AM ----------
I believe Moto changed something in the latest 92/93 update that's causing permanent VoLTE loss to almost everyone flashing 8.1 ROMs.
I don't think so....i had 67.5....for me also volte is not working...
Only devs can tell the exact reason. what i think is if we knew earlier then when we try to revert to stock fro the first time when everything was working fine(VOLTE). we should've skipped that 2 lines (Erase one's) while flashing stock rom
What if i have EFS backup of Stock Rom ?
By flashing efs backup of solves Volte issue ?
Please let me know if anyone have idea about the same....

If you did the backup while your VoLTE was still working only then it could be of some help.

Well i had the efs backup when Volte was working and it did not work.
Not only is VoLTE broken but the network keeps refreshing itself.
Never thought flashing a custom ROM will make me get another phone but there's no other way.

Really sad to hear all this going on. Why isn't there any fix to it? Hope someone can resurrect VoLTE on our devices.
I'm on Oreo Pixel Experience and I'm scared to flash other roms. What should I do? Does any backup help?

As far as I've seen, No.
Restoring stock via fastboot or restoring efs backup via TWRP didn't do any good.

Thanks! I hope that too.
I'll be saving for a new phone and by the time watching if a fix appears.
someone please help us..as soon as possible
I managed to relock bootloader and fastboot stock. I skipped erase modem commands and 4g is working, however, Volte was not fixed by this.

I have this idea which I'm not sure will work or not:
A friend of mine has a Moto G5 plus too with everything stock and VoLTE working.
If I backup everything on his phone via TWRP and use that backup file and restore it in my phone, would it work? I'll find out tomorrow.

Sensors

Guys, I know this is not the topic, but I do not know where to write. my g4plus bike does not work anymore nor a sensor, it stopped out of nowhere. I already did everything possible, about installing different roms or hard reset etc. Does anyone know how to solve it?
Please, post in English, not all people undestand portuguese and post the question in the right forum, this is only for guides or news, post it on the Question forum
Thanks

Best thing is factory reset and/or flashing stock fastboot rom. That's what you can try. Backup recommended!

Then consider a hardware problem. Claim warranty if possible.
There's no other solution you can do then reflashing the whole rom/firmware from start.

I'm thinking that it might be hardware, but it's over:
Difficult to claim warranty if the bootloader if unlocked

You can lock it again and several people here claimed warranty even with relocked bootloader. Not every repair center check the warranty. You can try it

Fingerprint apk needed

Hi everyone.
I have been facing fingerprint problem since yesterday. It was working before and suddenly it showed fingerprint wasn't working. I hard reset the phone and everything. When i try to register my fingerprint it shows its having an error with my fingerprint sensor. I looked into the sensors test and it showed null. Btw the fingerprint app is missing from my app list even when i looked at system apps. Has anyone came across this?! I looked through forums but no concrete solutions were available.
My phone model is SM-960N which has Exynos 9810 chipset. Can anyone extract and share the fingerprint apk of this model ?! It would be a huge help.
Thanks.

Did YOU flash a different firmware or your same OEM firmware?
Did the fingerprint app return?
Is it functioning properly?
Your post is vague.
