I cant delete fingerprint when i dont have them...also i cant add them too :?

deleted Com.qualcomm.qti.fingerprint.biometrics.service in app managment and clear data and cache and still cant add finger...photo shot work in 2 of 6 situations...
[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
If you wasn't able to add a fingerprint since the first day you received the device you're also fine! Makes the job shorter. Just skip the step of deleting the fingerprints and go on with running the fingerprint calibration.

In app management you only need to stop the running process! DON'T DELETE THE HOLE PROCESS/APP!!!

After that delete the cache and data from

Com.qualcomm.qti.fingerprint.biometrics.service process!

That's all you need to do there...

Restart device and enjoy working fingerprint.

If you already have deleted/uninstalled the hole app then you probably need to install the hole firmware​ again.

Or use a backup of the app/process if you have.

[LeEco Le Max 2 Guides, News, & Discussion] Lizard82:
Maybe it's related to the Rom from cucou... Have you tried another based on eui? I think i remember a couple of weeks ago some people of our German Le Max 2 group on the Android-hilfe board where having trouble with this Rom as well.

If i will find the time tomorrow I'll have a look inside the thread. Cucous Rom was very popular in Germany some time ago. Much more conversation related to this firmware compared to XDA... I'll let you know what I can find out.

In the spare time maybe you can do a test if you facing the same problem with other eui based ROMs.

After two weeks of using Resurrection Remix, I decided to go back to the 20s and others ROMs based on stock and check fingerprint. Now I can't take phonos when I touch the sensor. Stopping "com.qualcomm.qti.fingerprint.biometrics.service" doesnt work. Smart Phone Lock app doesnt work too. Even I tested flash configs of fingerprint - it also does not work.

I just give up, waste of time.

ok, i give up on it.

no matter what i do, fp sensor is dead and screen flickering still present.

last thing i tried was:

-wiping everything and formatting

-restore qfil dev-rom with flashone (got the split screen issue)

-flash 14 cn (still splitscreen)

-flash 15s cn (splitscreen gone)

-flashed all the remaining original roms

after every flash i tried to register a fp and take a picture with the cam (option enabled in settings of course). it does not react at all.

lizzard 82‘s method and the smart phone lock app also do nothing.

it's obviously broken.

at least i found what's causing the splitscreen issue.

Finger sensor really is rubbish on these phones. Turned mine off and don't bother with it. Mine works but soon as phone been off for more than a few minutes it takes so many attempts to make it work its pointless. Though if you try it immediately it works perfect.

In my opinion it's in the wrong place anyhow. So much better being on front like my zuk z2.

Here is the logcat, it would just loop this over and over again, maybe its it just saying the the scan failed or something. Hopefully a dev could look through it and potentially help everyone with a Le Max 2.

No problems here! I have the Chinese 23S modem and the fp sensor never sleeps, although i have tried other modems that do put the fp sensor to sleep and almost unresponsive.

Flashing a rom doesn't change the modem/baseband/fingerprint driver!!

Please inform yourselves before saying such ##3**#! things!

Some users also say that latest developer rom modem also does the trick (419), for me only the latest chinese modem does the trick, maybe because i have the x820 chinese version, i don't know...

Here is the link for all modems, flash them in twrp, test and thank me later...
[LeEco Le Max 2 Guides, News, & Discussion] onecryon:
Hi,

thank you for the trick but i have flashed the chinese modem (23s) and nothing happens, is still not working :(
[LeEco Le Max 2 Guides, News, & Discussion] waj1234:
Thanks for this. Trying 419 on my x829 with Indian rom and its seems so much better so far. I find Indian rom pretty stable and happy with it so if different modem makes sensor better that's a good thing.

Not everyone is as informed as you. I did not realise the modem held the finger sensor as had not read every thread in detail.
[LeEco Le Max 2 Guides, News, & Discussion] bolof2:
Thanks mate, it did the trick! Never heard about these modems, you maybe got any explanation / link on what it is and how it works? Tried to look in XDA and duckduckgo, but all results explain how to use your phone as a modem :eek: lol

Anyway thanks again!
[LeEco Le Max 2 Guides, News, & Discussion] bwalter:
I didn't have the deep sleep issue but my fingerprint scanner was often sluggish and/or took multiple tries in general. I flashed the 419 Dev modem and so far it seems much more responsive.
[LeEco Le Max 2 Guides, News, & Discussion] Frexor:
I tested few Chinese and Indian + latest developer modem drivers on AOKP ROM - no changes, no fingerprint detection at all. Maybe I should test this on stock ROM, or wipe is needed?

I just dirty flashed the modem and everything went fine, maybe try reassigning your fp and remember to save 2 fingerprints of the same finger to improve accuracy.

Flashing 419 modem made my sensor work well for a while but 12 hours later it's back to being unresponsive 50% of the time so it's clear that changing modems may work for some but not all.

my sensor started working (partially) after applying a protection film!

the 419d modem really made it more responsible but i'm still unable to register a print.

it does vibrate now, tells me to move the finger around, vibrates again and again but it does not register.

try it, costs only a few cent. clean the sensor first.

i'm on resurrectin remix - m.

i hope this hint will help to find out what the issue with the sensor is about.

Hi All,

I bought a Coolpad Note 3 Plus mobile last month,

I tried to install custom rom on it, so I have rooted my phone, it went very well.

Then I tried to go to recovery mode to flash the custom Rom, the mobile didn't boot to the recovery mode after some time of stock boot animation it boots to normal booting process.

Then I tried to factory reset my mobile that's also again boots to the normal boot and back to normal.

But, the mobile works well without any issues,

I tried to flash the custom recovery through Rom Manager app, Tmrw recovery & flashfy apps but no luck.

Can you please advise what to do get the recovery of mode and install CM12.1 custom Rom on it

Thanks in advance

Hi,

recently i bought a Teclast X80 Dual OS China Tablet and put a 64 GB SD Card in it. It is recognized by the system and i can use it with the internal explorer app. Also i can read it with ES file explorer and also achieved to write to it when selecting it correctly.

But apps like "DiskUsage" or "FlickFolio" doesn't even show that an external sd exists. The problem is the tablet doesn't ask for sd access or something like that. Also i didn't found a setting or a possiblity to set permissions.

And on top it is not rootable at the moment.

Anyone? :/

[Nexus 6P Q&A, Help & Troubleshooting] spireite_uk:
I think this is a long standing issue with this app and this phone.

You launch V4A, it asks you to download the driver, it seems to work, asks for reboot... You reboot, go back into the app and get prompted to download it again.

I remember a fix I found somewhere that involved renaming or deleting a certain file before rebooting or something like that? but I find it annoying to keep having to try and use that flaky fix every time I change/update my ROM so I just wondered if there was a permanent fix out there, like a V4A .akp just for the 6P? Or do we know if there's a better workaround out there?
