hi everybody.
I got this system a few days ago.
When I try to update the car icon, the device need restart but stay on a black screen immediately after the logo indicated. (says wellcome nav system or Something like that)
Need to disconnect the battery and wait a few minutes and only then the system goes on.
Today the system remained on a black screen no matter what I do.
I tried to enter recovery but I do not know the keys order.
I tried everything listed here but it does not work.
This model may get to recovery in a different way?
Is anyone know a system updates for this unit?
thanks very much

Tried to install a custom ROM on my old N4 via Toolkit but got a bootloop on the Nitrogen logo. Right after the screen the phone would turn off. So, i rolled back to stock rom, unrooted and everything but now it seems the problem its even worse: the boot doesnt go past the Google logo. When the phone is charging i can access the recovery and even boot into Android. Off the charge it looks like i cant do nothing other than go to fastboot. If i choose the recovery option the phone turn itself off. I tried to install other ROM via TWRP when charging, but right after 2 seconds after the process begins, the phone turns off.
I think it may be a battery problem, but i wanna make sure it is so i dont waste money.
Thanks

hi buddy, problem is also happend to me, unfortunatly its not a software issue , its a battery problem, and its only fix with changing battery or you could turn on airplane mode (to turn off radio and only in custom rom) and keep using the phone offline.
Hello friends, I have a similar problem with my nexus 4.
I can use the device well if it is connected to a USB or plug. (If the device isn't connected, this turns off). But I can use TWRP without problems (works without connect to a USB or plug), I can install ROMS until finish, but when I want to start the system, only stuck on Google Logo and the device turns off (I tried to start the device but just stuck in Google Logo and turns off again) But if it is connected to a USB or plug works well without problems.
I tried to install all STOCK roms too but only work well when the device is connected. I think that isn't a battery problem because I can use TWRP (without connect to a usb or plug) and install every rom.:crying:
Someone would like to help me. Thanks a lot.

i told just above your post,that is a battery problem and only fixes with changing battery, the reason you can use twrp is that the voltage needed for boot phone in recovery mode is less than for booting the whole system with apps and radio functions
Hello today a screen replacement i ordered in aliexpress arrived and i did change it carefully (i did this process 2 times 1 in my phone and another in a cousin mi a1. No problems).
The thing is... after this i turn on the phone and the screen turns on but only until rom starts to load and then it comes black as if it wasn't turn on. The screen turns on also in fastboot mode but instantly shutdown when entering to recovery mode or normal boot as i said. The phone is working properly the rom loads and there is notification sounds and touch is working too.
If anyone can help me please. The only thing i can thing of is that the screen came with some strange malfunction.
EDIT: I flashed stock rom with flash_all and got the screen and everything working fine. I then tried again to flash a custom rom as i had before and screen failed to turn on again. Then i flashed stock kernel just to try if was it the cause and after this screen worked fine again but i lost wifi and probably there is other issues because of the stock kernel on a custom rom. I don't know if it may be because a different display driver or a kernel setting that may cause this malfunction. Hope someone can help me to solve this as i really want to use a custom rom.

Hello. Please. I have a damaged Lenovo k920 at home. The system will not boot showing only the reboot menu. Nova Rom did not help via OTG cable. He doesn't have a PC. Neither does the Lenovo downloader. Do you think the phone is completely dead? I will only get into Lenovo recovery but reboot will not change anything. The update will not take place in the form of OTG - usb. For a quality screen and good performance, I want to use it as an offline screen on a drone. Can you please advise me? The only menu that loads when turned on is the test menu - board, sensor, etc. Format, update, reboot. But nothing starts the system.
