1. If you search a little bit you find enough threads/posts that clearly say that it can be a hardware issue too. So go and figure it out.

2.vIn other cases it can be fixed by flashing the right firmware, rom or zui. I seems you read all this, didn't you? If you're unhappy with this rom, nobody forces you to use it. You can install cos 12.1 that comes with the device you bought and feel happy with that.

Some advice: Please watch your language and don't be rude.

On other devices you need to update the firmware too before newer roms can access them again. So don't say "fix that" in a demanding manner if you don't understand why it is so and that everybody on xda developers is working in their free time for nothing.

[Zuk Z1 Original Android Development] Mrmagnus:
So there must be problem in latest build of Lineage OS 14.1 nightly, because Everything worked fine in my older one....but I don't remember which one that was. I found in other forums people have the same issue with different devices on latest build, I will try to flash older versions....
[Zuk Z1 Original Android Development] CeperColddd:
Well then try clearing​ the credentials in Security setting... It worked for many...

How to flash stock ROM and from where to get it?

---------- Post added at 03:57 PM ---------- Previous post was at 03:54 PM ----------

My home button and fingerprint both stopped working, this mean I should be pretty sure that it's hardware issue?
[Zuk Z1 Original Android Development] CeperColddd:
Flash it just as u flash other ROMs

Stock ROM link :- https://www.androidfilehost.com/?fid=817550096634751170
[Zuk Z1 Original Android Development] Mrmagnus:
So guys I flashed 829 and 815 builds, and none of them working for me, fingerprint still missing. Any other way to make it works? (working on stock rom)
[Zuk Z1 Original Android Development] CeperColddd:
Try cleaning the credentials in Security setting... Might work
[Zuk Z1 Original Android Development] Mrmagnus:
I don't know what is this, teach me how... never done it before... :)
[Zuk Z1 Original Android Development] CeperColddd:
Use the 'Clear Credentials' option in Security Settings...
[Zuk Z1 Original Android Development] Mrmagnus:
This button is greyed in my settings, I can't use it
[Zuk Z1 Original Android Development] CeperColddd:
Then i dont know what could solve it... Sorry[emoji26]
[Zuk Z1 Original Android Development] ashokram343:
look how many ppl are facing fingerprint issues... .come on guys show one solution which works on every zuk z1 device.....
[Zuk Z1 Original Android Development] kalamkhan:
Using twrp?
[Zuk Z1 Original Android Development] CeperColddd:
Yup!!!
[Zuk Z1 Original Android Development] strongst:
As I already mentioned, the fp issues can be solved by many possible solutions. Not every solution is the one that you help for sure.

And you can see it's not a problem of this rom only, otherwise everyone cannot use fp anymore after flashing this rom.

So please stay on topic here, you received enough possible solutions and others are found in Q&A section as well(older ones).
[Zuk Z1 Original Android Development] kalamkhan:
Do I need to flash gapps as well?
[Zuk Z1 Original Android Development] Aris_Toteles:
Did you flash CM13 before flashing LOS14 after you went back to CM12?

Best way to get everything working (fingerprint, screen rotation, second sim card):

CM12 > CM13 > LOS 14 unofficial > ZUI > LOS 14 official

(important: reboot between flashes, make clean flashes)

If you already are on LOS 14, go back to CM13 and repeat the other steps.

This was verified multiple times in this thread (I also hat that issue before using the above flashing order).
[Zuk Z1 Original Android Development] Mrmagnus:
Guys I can tell you the problem is in this ROM, I flashed AOSP Extended v4.6 7.1.2 and Fingerprint working.
[Zuk Z1 Original Android Development] CeperColddd:
Yes... Use the respective gapps for cm12

---------- Post added at 05:02 PM ---------- Previous post was at 04:42 PM ----------

Are you even serious man... I am also on that particular ROM, not a single prblm for me...
[Zuk Z1 Original Android Development] Mrmagnus:
So where's the problem then? No fingerprint working on any versions of Lineage 14.1 , no hardware problem because in other roms I'm fine
[Zuk Z1 Original Android Development] Sharma_Ji:
Have any of the guys who are facing problems with fp even tried these steps, these would be the last solution, otherwise give your phone to service center to replace fp
[Zuk Z1 Original Android Development] olifee:
Please make sure the mod is active in Magisk Manager. If this does not help, it's better to ask in the thread where the hotfix is developed, the problem is likely device-independent (things worked fine for me out of the box, though).
[Zuk Z1 Original Android Development] CeperColddd:
Try the above steps.... If it doesn't help.... Then nothing can help... And for your kind information, almost every nougat ROM is based on this Lineage 14.1 ... Hope you dont blame it for ur problem...
[Zuk Z1 Original Android Development] kalamkhan:
Tried CM12.1, seems like my phone fp is damaged. Whenever trying to register started continuously vibrating.
[Zuk Z1 Original Android Development] Love7:
im on latest build and everything is working great specially fp sensor... im facing camera shutter sound bug from the start and new lineage gallery hangs up for some seconds when switching to videos from timeline or albums
[Zuk Z1 Original Android Development] VeerAmrit:
ZUI which version? And do we have to flash gapps each time and boot?
[Zuk Z1 Original Android Development] tyo14:

[MENTION=5426059]ashwin007[/MENTION] please merge pending patches of 14.1 branch for zuk z1 if you have any free time.

Please try to make snapshot built for zuk z1 more stable.

Note: this not a eta. It is just a request of infallible build of nougat.

[Zuk Z1 Original Android Development] tanmeshn:
Facing random reboot in latest build... Usually I used to dirty flash new builds but this 3rd October build I clean flashed and started facing random reboot, like 1 per day. Don't know the reason, also battery% gets stuck quite often.
[Zuk Z1 Original Android Development] tanmeshn:
I am on latest lineage os build, that is 3rd October build, and while using it for past couple of days my fingerprint scanner suddenly stopped working. This is for the first time i am facing this issue. Phone is not able to detect fingerprint scanner. So i thought flashing ZUI 2.5 will help.... Flashed ZUI 2.5 but still phone was not detecting fingerprint sensor. Then again clean flashed lineage OS, still sensor is not detected. Also fingerprint lock option just vanished from security settings. Anyway i can resolve this??? Or my fingerprint sensor is dead?
[Zuk Z1 Original Android Development] Love7:
Try flashing stock cyanogen

hope it helps
[Zuk Z1 Original Android Development] tanmeshn:
Flashed stock COS ROM via fastboot still sensor is not working. When I go to register fingerprint in stock ROM it keeps on vibrating and without scanning it takes my fingerprint. Maybe it's a hardware problem. Sad, my phone is 1.5yrs old now. How much it'll cost for repair of I give it in service center?? Any idea??
[Zuk Z1 Original Android Development] Akshatpunj:
6-8k approximate buddy as they will replace the whole digitizer etc.

You can also get it imported and get it fixed at a local shop. That should cost you less.
[Zuk Z1 Original Android Development] Love7:
dont know for sure

you should visit your nearest service center and i think they will replace display too and it will be around 3 to 4k if i were you i would probably go to a local shop or buy new phone

some of my friends bought z2 plus at 9200 at paytm and one of the main concerns in that phone was camera quality which is far batter than zuk z1
[Zuk Z1 Original Android Development] CeperColddd:
Get the Touch Display and Digitizer on Amazon..

[Zuk Z1 Original Android Development] tanmeshn:
Thanks buddy. Thnx [MENTION=7920582]Akshatpunj[/MENTION] [MENTION=8338342]Love7[/MENTION]

After your replies I changed my mind. I won't repair this phone. Itll cost too much to repair, instead I'll wait for few months and buy new phone.. I'll use pattern lock for now... Even my 3yrs old Moto g2 still works absolutely fine. Won't buy any Lenovo phone in future.
[Zuk Z1 Original Android Development] CeperColddd:
But ZUK Z1 is one of the best phone that i've ever used...
[Zuk Z1 Original Android Development] tanmeshn:
BTW, Xposed framework will work with lineage OS??? Plz reply
[Zuk Z1 Original Android Development] CeperColddd:
YES¡!¡!¡!
[Zuk Z1 Original Android Development] tanmeshn:
Thanks... You tried?
[Zuk Z1 Original Android Development] CeperColddd:
I am not a fan Xposed... So i haven't used it till now.... But other Z1 users have reported that it works...
[Zuk Z1 Original Android Development] tanmeshn:
You don't get home button as separate part?.. it's embedded into screen/digitizer??
[Zuk Z1 Original Android Development] CeperColddd:
Yes... It all come as a set!!!
[Zuk Z1 Original Android Development] Akshatpunj:
If you go to a service centre they will tell you that it comes along with screen/digitizer that's why they replace the whole screen.

My FP stopped working on COS and i got it replaced while it was still in warranty but again it has stopped working and now I'm living with it.

But you can get it imported as i said in my last reply.
[Zuk Z1 Original Android Development] strongst:
Guys, that's really off topic in this rom thread. Please discuss in one of the existing threads in Q&A section. Thanks :good:
[Zuk Z1 Original Android Development] Akshatpunj:
Sorry, just wanted to help. :)
[Zuk Z1 Original Android Development] tanmeshn:
Sorry buddy.. won't happen again... BTW Xposed doesn't really go well with lineage. Phone started lagging so uninstalled it. Those who want to use Xposed modules it's not possible on lineage OS.

Fingerprint issue

Hi

New in here...

Just flushed lineage over cm on my zuk z1.

All is working but pingerprint option is gone.

I can't find it in settings anywhere.

Does lineage support fingerprint on zuk z1?

Anyone can help?

Thanks
[Zuk Z1 Original Android Development] strongst:
Please have a look at Q&A section, this is due to wrong firmware prior to this rom. You need to come from cm13(see pp) or zui.
[Zuk Z1 Original Android Development] ZeevG:
Thanks,

Not sure i understand,

I should come from cm13 before lineage?

If so,

I think i was on cm 13 but not sure

What can i do now?

It is done, so is there a way to fix this ?

Thanks
[Zuk Z1 Original Android Development] strongst:
As I mentioned you need to flash cm13 before nougat based roms(LineageOS 14.1) or flash zui 2.5: have a look at Q&A section, there are several threads covering this topic https://xdaforums.com/zuk-z1/help/fingerprint-suddenly-disappeared-t3676891 and https://xdaforums.com/zuk-z1/help/fingerprint-stopped-t3290228
[Zuk Z1 Original Android Development] :
Fingerprint lag has gone now. I think someone is working on it. Thanks for the great ROM. Only ambient display is missing and GPS problem is there else it is the best ROM for zuk z1.
[Zuk Z1 Original Android Development] Bugs G:
Use a zuk z1 for 2 months! I have not had any problems with the scanner and the GPS! Spontaneous reboots disappeared! Very satisfied with the LineageOS!

Ps.The only thing that bothered! then there is no U-touch on the scanner. :(

Hi I did like so from cm 12.1 stock :

Wipe

Flash nuclear for MM

Boot up

Wipe

Flash LOS

Flash Gapps

Still no fingerprint, when the next wave of roms for oreo will start coming out I should go back to stock then zui then los then anything else in oreo?
[Zuk Z1 Original Android Development] strongst:
You can try with zui 2.5. For oreo there are no other requirements, I'm sure.
[Zuk Z1 Original Android Development] Gvina:
Well I'll make sure I'll have a day to test what works and what doesn't
[Zuk Z1 Original Android Development] tanmeshn:
I know this may be inappropriate question in this thread but still I want to ask.

Will lineage OS 15.0 support substratum since Android Oreo has OMS support by default?

Krack vulnerability has been fixed already in this official lineage version right?

I hope we still get security patches even on final version! For the meantime I will check lineage out! I'll just make an nandroid backup so i can go back to nuclear anytime.
