Flashlight don't work - How to test if it is broken - LG Optimus L90

Hi, first of all, sorry for my bad english.
I hope you understand
I've installed LineageOS 14.1 and all work's great
Then I've installed a new nightly and the camera led flash didn't work anymore.
Not as flashlight and also not as camera flash.
So I did a "factory reset" and installed the first LineageOS build.
The LED still doesn't work.
I wan't to test the Hardware if the LED is broken.
I used following code to open service menu but nothing happens. *#*#197328640#*#*
The entered code dissapear and that's it.
How can I test the Hardware? some tipps to reactivate the LED?
Thanks a lot

Noone?
I need some help, please.
How can I test the Flashlight to find out whats wrong. Is it a soft- or a hardware issue?

Factory reset is not enough. Recommended is clean install, wipe at least system, cache and dalvik, then flash previous ROM. If it still doesn't work, flash KDZ.

First of all, thank you.
With "factory reset" I mean I made the following:
Code:
1. Boot into TWRP
2. choose wipe
3. choose advanced wipe
4. select: Dalvik/ART Cache
System
Data
Internal Storage
Cache
5. swipe to wipe
6. flash previous ROM
So it doesn't work. How can I flash KDZ?
The same way like LIneageOS?

No its different look around on xda for this device flashing kdz and you'll find it.

If installed D40520a_00.kdz
Flashlight still does't work. So it seems to be broken :crying:

Yeah it probably is.

Hey there. Your flashlight is not broken. Trying adding the widget to your lock screen. Or if you want to test type this in your dialer 3845#*405# and a hidden menu will appear from where you can test the features of your device. But if you reboot your phone they reset. I hope this helps you.

Hi there.
You're right.
I've flashed the new LineagoOS nightly and the Flaslight turns on for about 1 or 2 seconds and then turn out.
This happens every time i've tested it.
The code 3845#*405# doesn't work.
I see a message saying "USSD code running". That quickly disappears and then nothings happens.
It seems that I can't add the flashlight widget to lock screen.
any suggestions how I get the flashlight work?

Hey there the code won't work in custom roms. It is only for stock roms.It opens hidden menu. Custom ROMs take the advantage of your phone while it mat offer you a faster phone.Please revert back to stock ROM. Ik stock ROMs are slow.But it is much better to stay with stock ROMs with root and custom recovery and xposed.Check flash light once you flash stock recovery.
Hope this helps ?

First of all: Thanks a lot.

What means xposed? Some kind of app?
I've flashed D40520a_00.kdz ago but Flashlight also didn't work.
It "works" since I've flashed ne nightly...
If I flashed the stock rom all Preferences would be reset, right?
So why did flashlight not worked if I installed D40520a_00.kdz?

Hey take a backup of your internal storage.Then in Lg flash tool do a csc flash.Flash correct kdz file.
Try some Google play apps for turning on flashlight

OK. I try it once again.
I usethis guide to flash KDZ. Is it OK?
What is a CSC flash?
Is it an other choose for "3GQCT"?

Hi there.
I think you mean CSE Flash?
I flashed my phone descripted in this Guide.
Type: CDMA
Phonemode: Diag
KDZ: D40520a_00.kdz
Upgrade with CSMG Client: CSE Flash
After the first setup wizzard I get a software update. Now the software version is: v20b-EUR-XX
Android-version: 5.0.2
Kernel-Version: 3.4.0+
Where in the hidden menu 3845#*405# can I found a entry to test the flashlight?
( No apps for turning on flashlight works )

I've tested every menupoint and I found nothing.
With the stockrom I have no Torchlight symbol in quick settings (when you move from the top to the bottom where you can activate wlan, bluetooth etc.)
I add a torchlight widget to the homescreen. It turns on for about 2 seconds then turns off if I activate it.
The SOS-function works. Lollipop or KitKat stock. always the same result.
Is it possible to flash the complete smartphone.
It seems like there's a progamming block or some kind of settings that's wrong and that won't reseted with stockrom flash.

Download flashlight from playstore and test

it is always the same with every app.
The LED works for about 1 second than turns off.
Flickering works at all.

Try contacting lg service centre for a possible fix.Try flashing a bootstack or a custom kernel.I know they are not related to flash light but still trying is not bad at all.

[ROM][7.0][Nougat][AOSP] Android 7.0 AOSP for Mi Note Pro (LEO) by Ivan - 20161115

We have ROOT.
As you read this message, unofficial AOSP porting of Android 7 / Nougat has been done. As usual, it is by none other than Ivan. This has gone through few closed BETA and is being released for public now.
I am on this ROM for few days now, and is definitely a daily driver. But, it has its own issues - that is why it is BETA. But, at least I can live with it.
Lots to enjoy in Android 7.
Current noticed issues that are open as of now (at least for me).
FC on settings app after reboot. (Click close app and continue, it continues)
Rare FCs on browser app
No options to configure LED setup (probably not part of AOSP?!). Missed call doesn't show red LED.
Root not available yet
Camera - under video crashes when we choose 1080p. Need to clear data to open camera again
Camera - some reported noise in quality & slow frame rate on video
Security patch level is old - 5Aug'16
WiFi shows as no connection, but actually it has internet and it works
Call history limits to 500. How to modify this?
Gallery FC when edit – Open camera. Click the last image for opening. Click edit icon. FC.
Charging from PC / Laptop – Connect to PC / laptop. Pulldown settings from notification bar. Select – charging mode. Charging will stop in few seconds. Change to ‘File Transfer’. Charging works.
This is the first public release kindly allowed by Ivan. Any further issues, please post here - I will be glad to pass it to Ivan and lets hope for the fix.
Download Link: MEGA
ROM uploaded to MEGA for international user's
PS: This is NOT my development. I am passing the ROM developed and maintained by Ivan. Any credits - should go to him.
If you have any issues, Please provide logs for the developer to debug,
adb bugreport > bugreport.txt & give me the bugreport.txt
logcat > /sdcard/logcat.txt and dmesg > dmesg.txt & give me logcat.txt and dmesg.txt
How to install?
Make sure you have bootloader unlocked.
Flash the ROM in recovery. Flash from Ivan's 3.0.2 recovery.
Reboot and setup your device.
Reboot to recovery and flash GAPPS - I used GAPPS from http://opengapps.org/ (64 bit, 7.0, micro/mini/pico)
Don't Don't Don't flash SuperSu or any ROOT zips - this will kill the network!
Thanks to @fobikenobi for pointing to the tutorial
I used GAPPS from http://opengapps.org/

I have the same experience, the icon shows you internet is not connected but actually connected and the worst thing is that it cause the setup wizard cannot continue due to no wifi network is connected !
Also, the detection of the SIM is a problem, not always work, many times it cannot detect the SIM card !
A partner of another forum has discovered how to enter and we don't have the connection problem:
- Install only the rom
- Configure (Probably the system say that you don't have internet, but it works)
- Reboot, install the gapps.
- Enjoy and test!
What twrp did you use? Can you post it here but 100% working one.
I currently have 2.8.0. Installed becaouse all of the 3.0 versions i installed gave me this is for leo, your device is libra or something like that..
@brajks , I use the 3.0.2.0 by Ivan.
You can find it here

Ok, internet works, but still shows warning above icon, that internet not available.
2) Smart lock is missing in this Rom?
3) after i.make call, phone reboot.
Not for daily use.

Installed it with 2.8 twrp
At first worked like a charm. But after a full day of use, wifi stops working and apps report no Internet connection.
Sadly not for daily use still.
Hoping for future updates.
Keep up the good work!

Asking password after custom rom first reboot

Hi, when I flash a rom (I tried a lot of them) and do the first reboot (after wipe etc.) it shows a black screen asking for a password. I tried every single password I've ever set in my whole life but nothing works...
Is this normal ?

Fingerprint Sensor Replaced, how to re-calibrate?

My p10 was just got back from warranty claim for broken screen. When i turn it on, there was this menu asking to recalibrate fingerprint sensor because the sensor was just replaced (not inputting new fingerprint). It was unclear how i should do it at first, however after few attempts it was supposedly asking me to rotate the phone while the finger resting on top of the sensor.
Too bad, i think my first few failed attempts may have miscalibrated the whole sensor.
Anyone knows how to get back into that menu?

I replaced a broken display on a P10 VTR-L29 and the fingerprint button is not working, everything else is. At first I though the display is faulty, but now I have doubts since the fingerprint option on the menu is just not there. I re-flashed the same version of the firmware (B369) via TWRP and the problem persists. I may have to try a factory reset.

So this is how it ends when noobs messing with phones they don´t understand.
-You can unlock bootloader by paying some bucks to DC phoenix.
When you have no fgingerprint sensor options enabled it points that:
- the fingerprint sensor is broken
- the fingerprint sensor is not conected right
Hi alll
I had the same problem after replacing my screen.
I used Quick tuneup, and since the fingerprint sensor work correctly.

Sorry bro, my fault, i thought you are the one who asked before you.
You didnt say anything about your problem just asked if there is a solution and that you cannot unlock bootloader. With this info no one is able to help you. But anyway:
1. method:
-Remove existing fingerprints
-do a factory reset
-add a new fingerprint (when finger not scaned properly try to push a little bit harder on the sensor and rotate the finger)
-After the new fingeprint is scaned it should work well
2. method:
-after you recieve OTA notification (every month) go to settings/system updates/ there are three dots in upper right corner and select "get the whole latest package". This will download the whole firmware and perform a factory reset low level and this should work (if simple factry reset didnt work for you).
if this methods don´t work i will suggest you to go to phone service.

Can't access ProjectMenu

Hey there! So I have a problem. I was trying to go back to stock with a guide in this post: https://forum.xda-developers.com/p9/development/rom-huawei-p9-magic-rainbow-t3601064 . When I flashed update.zip, I was stupid enough to reboot my phone. Everything was looking fine. Untill I tried to access the projectmenu to se the USB mode to Manufacture mode. I entered this code into my dialer: *#*#2846579#*#* . The dialer just went back to the recent calls menu. So I tried to update, but the update failed. The last thing I tried was to flash the stock rom again with dload, but the problems kept occuring. I hope someone can help me, because I'm clueless.
Were you able to solve this? Im currently having issues with magiskhide which could be because of logging not being turned on so I tried to access the project menu and just like you said, it goes right back to the call log without the project menu popping up
