FP hardware not available! - Lenovo P2 Guides, News, & Discussion

Hey guys! I have a problem with my P2, some times I get fp hardware not available! A lot of times it works again after activating/deactivating developer mode and restarting the system! I'm on LOS 14.1 but I tried AEX and Havoc too

Funny, i'm getting the same thing. I'll try the developer mode trick.

same here
same happened to me i am on stock rom. some days back i was on aosp extended and everything was fine. and yesterday i got this problem "fb hardware not available' i tried factory reset n flashed los 15 but it didnt help now back on stock but fp still jot working

I lost it on stock s251.. only gestures were working in Safe mode. Tried los 15 with the fpgesturesfix zip .. i only could use fp sensor once. But it stopped the next morning. Any fix? Going back to stock (7.0 /6.0) will help?

Developer mode trick didn't work for me, so i switched from RR to CRDroid, but no joy. Maybe something wrong with oreo sources, maybe stock fixes it... Maybe, maybe...

Seems that it's working now for me..I just did a full wipe, with internal storage too, and than flashed back Los 14.1, then I activated developer mode and restarted the system...it's working until now..

Well, my fp sensor also came back after doing precisely nothing just started working again. Weird.

Flash these files , according to your rom base, after flashing rom. Works for me. ?

on stock

I was on stock and my fp was faulty. I am not sure but u can try the Aosp fix. Don't blame me if your phone blows up as I use these files with custom roms.

[Q] Anyone succeed with GPS with custom rom

Hi all,
Did anyone able to use gps with custom rom ( I would say CM base). I research and try everything that's I could find here but not success.
Every time I do clean wipe everything including a internal storage. So that will nothing left behind.
I know that stock is work fine with gps. some said that install and replace stock but I have no idea that what file will left in our device when we delete all.
Always had the same problem when running Paranoid Android (not tried other ROMs). Had to return to stock, where GPS runs fine. Would also love to kknow how people have got it functioning.
I am trying too. I modified gps.conf files, tried some workarounds mentioned in cm11 thread like restoring GPS Status backup from stock with titanium so far with no success. Some people say that it works but it doesn't on mine whatever I do.
I run on CM and I don't have any problem. Everything works fine with gps and I didn't use any fix or something similar.
I'm on CM 11-20140627 and I have 1032 phone.
Interesting, why does it work on some while it doesn't on others? Maybe some variants are having problems...
I have xt1033 asia version.

Which recovery did you use?
CWM
As I wonder is about library missing or some partition need from stock ?
I've also been using the micro gapps package, would this matter?
I had problems with Paranoid Android and GPS too... If anyone know something about that, please comment!

I am having he same problem on XT1032 running Carbon ROM. GPS worked fine on stock, no signal with Carbon.
I found many answers saying to flash stock and then reflash custom ROM. I will try it, but I wonder, how does this help? Isn't the phone restoring the whole system? Do I have to keep the gps.conf from stock?
I've read in some CM thread on here you need to flash stock ROM then enable GPS and get a lock. Once you've done that then flash your custom rom. Sounds STUPID and dosent make sense I know, but a lot of people say this is how they got it to work.
EDIT: I can confirm. I've just flashed stock 4.4.4 and played around with google maps. Flashed CM11 nightly and my GPS is now working ok

Did you wipe anything, like Dalvik, Cache and Data, or you just flashed it over?

Sorry people, I was so happy to have my phone back working, I forgot to write it back here.
Yes it worked indeed, all I did was flashing back the stock, going outside to have a gps lock with gmaps, then re-flashing back the Carbon. I also kept a copy of the gps.conf, but I never needed it, the GPS got a fix quickly. Working fine so far, it only takes some tens of seconds to fix, from time to time.
I can't remember if I also did all the wiping, I think I didn't, but I made so many trials in a couple days, I am not sure.
Thanks a lot guys!

Yes, this worked for me too on PA.
I couldn't even see a single sat (it wasn't just a lock problem). No matter with gps patch, gpx fix app, or gps.conf I used.
What I did?: Back to stock, lock GPS, flash again the custom ROM (but don't wipe /system!).
Good luck on that guys, it should work for you too.

GPS works fine on this unofficial CM11 rom for me. Stable daily driver rom for me, YMMV.
General advice is to:
- make sure you get a GPS lock on stock rom first
- flash CM11 (or other custom rom)
There may not be a file left on the device. it may just be that stock contains the code to initialize the GPS functionality on the SoC or chipset firmware. Whatever, it works...

OPO Freeze and Reboots Constantly! HELP!!!!

Okay So I had been using CM12.1 Nightly when this first happened. After switching on my phone, within two to three minutes my phone would hang up, freeze and reboot! It used to happen all the time.
After which i downlaoded stock Cyanogen OS and flashed it wiping every partition possible. After a almost 3 hrs of use this problem started occurring again even on stock rom!
Also the gestures stop working like only music and camera gestures work and not Flashlight even if it is turned on. I read on a few forums flashing modem helps but didnt quite work out! Please help me out soon. My phone is almost unusable right now!

What method did you use to flash the stock Cyanogen OS? Recovery or fastboot?
I first flashed 17 Build number with Fastboot! Had no good....Changed kernels to AK and Boeffla and back to stock no good
Then I downloaded the entire Stock 23 build and flashed it...no good
Help me! Please
Only if I format everything it holds stable! I formatted everything and flashed build 23 again 2 hours ago! And rebooted now with AK kernel! Lets see....Any logs u want me to submit?
EDIT: Freeze and rebooted! Same thing happens with Boeffla kernel! Though I guess I am the only one facing this issue and its not a issue with the kernel! But still I'm fastbooting the stock kernel from 23 Build now!

Ambient display keeps screen backlight on

Hello.
My problem is that sometimes, when I receive a notification, ambient display turns screen on to show it (as it should do normally), but then, when it is supposed to turn screen off again, it only goes black, but the backlight is still on. It's hard to notice, but I don't want the backlight on, using battery, when I think it's off.
The only way to turn it off is by activating ambient display again (moving the phone, waving in front of proximity sensor, pressing power button), and then it would show my normal lock screen and then turn off, until "something" makes it leave the backlight on again.
Anyone have/had/knows this issue? I've used Mokee ROM, now I'm on RR and it happened on both, I don't remember if it happened in CM. Could it be something app related?
Thanks.
Yeah same happened with cm 12.1 latest nightly too.....just checked it now...
The Answer
Hi there !
When you have installed the custom rom, you have probably flashed directly from another custom rom , is this correct?
If so, it may be your phones drivers slightly messed up at the moment seeing as it has different parts from other roms, depending on how you flashed it.
My solution would be to flash the stock firmware , which can easily be found in the forums, and then flash twrp, then your rom of choice. If that doesn't work, its likely a bug in that specific build of the rom you are installing , seeing as another person who has replied has had the same problem .

That's strange! I guess it may be something like the drivers you said, because just one user said that have the same problem, but I'll have to wait until I have some free time to flash stock and root and flash CM and restore all apps and that again... I hate that part of installing another ROM.

Ok, I have spent some time thinking about this one for you, as I really want you to get this one fixed!
Although I need abit more information.
1) Does the issue occur on stock rom?
2)Are you sure it is not a problem with the build you are running?
3)What exact steps did you use to flash the rom?
To show that you appreciate my help so far, please click thanks

Thanks!
1)I can't tell if it occurs on stock, because on stock I use moto display (which doesn't have this issue).
2) I'm almost sure, because I've used 2 ROMs and both do the same. Maybe I'll have to try with CM nightlies?
3)I followed the guide in "general" section to flash stock using fastboot and android sdk. After that, I booted on stock, then rebooted to bootloader, flashed TWRP, entered to recovery, wiped data and then flashed RR ROM with it's gapps and then flashed moto camera and gallery. After that, wipe dalvik and cache and rebooted to system.
Right , ok. I recommend trying one of the cm12 nightly builds, seeing as they worked on my phone fine in terms of ambient display

Well, the other user that commented on this post was also using latest CM nightly, so I'm not very positive about it, but I may try it when I have time.
Well , looking at all of the information In this post , I think it is safe to say ambient display is not fully working on many roms :/
I installed a new build of cm12 earlier, and I found that sometimes the backlight will stay on , but other times it is fine.
If you want to work on this together, email me at [email protected] , and then we can look into it abit further ?
I will take a thorough look into the forums to see if others are recieving any problems as well .

Flashed ROM, Sensors stopped working. NEED HELP!

Hey guys I have a Sprint S6 (g920P), my phone has been rooted since last April, but I haven't tried flashing ROMs until recently. I recently flashed XtreStoLite, quickly realized that it doesn't support sprint phones and then flashed the Stock ROM found here: http://forum.xda-developers.com/spri...-root-t3075448 and finally the Renegade ROM. The flash was successful, but I soon found out I have lost a lot of functionality in my phone. My sensors stopped working. My phone doesn't count steps anymore, can't auto-rotate, IR Blaster doesn't work, Heart rate sensor doesn't work, waving your hand over the front screen doesn't wake the screen anymore. The only sensor that seems to work is the fingerprint sensor. I have tried wiping data/cache and reflashing the stock ROM, at the link mentioned earlier, but nothing has solved this issue. If anyone has any idea what is going on, that would be very helpful!
