UPEK fingerprint (Lenovo) not recognized by Ubuntu 18.04

I have Lenovo Edge e420s with a fingerprint:

Bus 001 Device 003: ID 147e:1002 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor

Unfortunately, Ubuntu (or Gnome Users settings) does not recongized the device using fprint_demo or the Users settings.

Funny is that Fingerprint GUI, recognizes and works.

My real problem is that I want to login with my fingerprint. Fingerprint GUI does not support it and Gnome-Users/fprint_demo doesn’t recognize the device.

Any idea how it can be fixed?

Thanks

Flashing Lenovo Vibe K5 to Stock ROM

Lenovo Vibe K5 is up and running in CM 13. But, I need to flash stock ROM on it. Now, I have tried to flash with TWRP, but that didn’t worked for stock firmwares. I have seen multiple tutorials, in that, they are using QPST and flashing it easily. While I am having problem, because my device shows as non Qualcomm device. It shows as RELINK HS-USB QDLoader instead of Qualcomm HS-USB QDLoader. I have installed the Qualcomm drivers correctly.

Ubuntu 18.04 HDMI not working lenovo legion y530

my laptop’s HDMI port is not working and I don’t know why exactly, I am running Ubuntu 18.04 alongside windows, on windows it works just fine. The laptop uses Nvidia graphics card gtx 1050, I have the latest driver installed (430) and I tried many other versions and did not work including version 390.

I had Ubuntu budgie on this laptop before and it also worked and didn’t work after that.

I would appreciate some help with isolating the problem to solve it, is it from the driver or port not detected etc.

Also I might have to say that xrandr doesn’t return anything saying that I have and HDMI port

Lenovo Yoga 730 Wifi not working with Ubuntu 18.04.2 LTS. Wifi Card tl8822be

I just installed ubuntu 18.04.2 LTS on my Lenovo Yoga 730, and the wifi card is not being detected. I’ve searched the askubuntu forum and have seen that others have had similar problems, however they were with different Yogas and different Ubuntu versions. So far, I’ve downloaded the rtl8822be driver and unzipped it. I have no idea where to go from here, and any help is greatly appreciated.

Thanks

Lenovo tab 3 7″ TB3-710F Android 5.0.1 won’t start after installing wrong TWRP

Basically I wanted to root it and every TWRP I tried came up an error that the file was too big,. moments later I tried different versions..many other versions btw,, scaling down to the smallest in size was 2.0.1.2 I think..

Anyway, it got stuck in a bootloop for about 2 hours. Mind you the computer makes the beep everytime I connected it and reconnected, so I thought it’s still alive. Now, it won’t turn on and I’ve tried most of the method’s to get it flashed but nothing even lights it up… brick

I have tried most XDA and Google without any possible fix.

Lenovo Yoga Tab 3 Pro (YT3-X90L) factory image, OTA update or backup needed

i was playing around trying out some new stuff with my yoga tab and locked it.

I’ve tried to factory reset it, but it’s still locked. I’ve tried to flash twrp in hope to do something more, but to unlock my tab in locked state isn’t allowed.

There is an old Google Account on it, but i can’t remember it and now i’m sitting in front of my tab and staring on it and thinking about how to help my self. I can’t, i need your help 🙁

thank you in advance for any help i can get

UPDATE:

I’ve tried so much things now. 1.) https://www.youtube.com/watch?v=nCzrnnh2K1w I was able to follow this tutorial to minute 9:08. But the option “Email and password” is not there anymore. I guess they patched it with 6.0.1. 2.) I tried to flash a stock rom or twrp with LenovoDownloader(QcomDLoader). The stock rom file is: Lenovo_Yoga_Tablet_3_YT3-X90L_ENG_S200028_1609230146. even its a german device this file was the only one i could find. But the LenovoDownloader won’t recognize my device. The windows stays white, no entries. I guess i installed the correct driver for this device and Windows recognizes them as removable device if i plug it in via usb. 3.) i’ve tried to use adb and fastboot boot oem unlock. But this commands aren’t working in locked state. 4.) With a trick i could open the Settings and was full of hope to active the developer options to set usb debbuging to active. But this developer options aren’t available either with this “user”. 6.) there is an apk for showing the “Email and password” interface. I could install it, but it force closes right after starting it. 7.)I’ve tried several tools to bypass this FRP: WinDroid Toolkit, D-G Unlocker, Realterm, but NOTHING.

What could i do further? I’m out of ideas right now
