Everything I was familiar with on my head unit disappeared one day when I started the car and the "windows embedded CE 6.0" start page was showing. I'm at a loss and don't know what to do or where to start. Any help and suggestions would be amazing. I was gonna post a link but it won't let me since I'm new.
Have you tried going into recovery and resetting your system?
If you don't know how to do a reset; detail which system you have and I can tell you how.
Hello, so lets get straight into it. My A7 2016 has been getting on my nerves recently as it has started randomly shutting down (When i launch apps i have noticed) and it also boot loops but all of this is fixed when i have a charger in. Any help would be appreciated
Edit: Some extra info since not very detailed
Model Number: sm-a7100
Version 6.0.1
I also want to mention i rooted it recently but since its hard to find a ROM i decided to un-root but while it was rooted i did a battery calibration and to add i never had this problem before rooting and also i have hard reset/factory reset my phone and still same issue
Cheers
Hi guys,
So need someones help as ive tried searching everywhere and can not find a stock android rom for the yoga book.
Ive tried the YB1 X90L but the installation fail's
Its my sons Yoga book and he updated the system via settings. Update looked as though it went through ok but then while optimising apps it just kept on restarting and starting again. Like it was in a loop, I decided to hard reset the unit which was successful but now on start up its asking for the last person who signed into Google. Yep my son cant remember the log in
The unit has never been unlocked or messed with, I have a slight idea of what im doing but any help would be much appreciated

Hello,
I recently installed my headunit from seicane (seicane S305690G) , but I noticed that sometimes the unit has to boot up twice.
First time it boots, it goes asfar as "android is starting up .." and immediatly after that the system reboots, again, second boot has always worked so far.
Any idea if doing a master reset to factory settings could fix this? and what exactly happens when i do a factory reset, my headunit currently works on oreo 8.1 wich i'm not really fond of, will a factory reset or undo all things seicane has installed? i have the feeling the OS isnt all that stable, the headunit also takes an entire minute to boot, idk but that seems a bit long no?
Another thing I would want to do is change the bootanimation, there was already a standard app on the unit called bootanimation that i can't remove/uninstall, after some digging i found the bootanimations app where you can download other bootanimations, but for this to work i need to be able to write to system/media folder wich i have no acces for , any idea's on how to overcome this, preferably without rooting, if i need to root it i'd preferably install a diffrent Firmware like android 7.X if that's possible and compatible with my unit offcourse...

Question 1: The unit checks on startup whther new programs have been installed and does an optimization step building the dalvik cache for that new application. One of those applications is corrupt, broken, whatever. It crashes the process and your unit restarts. The second boot either skips the apk or now it is going correct. so check what you have installed as 3rd party apps and install/deinstall one by one to find the culprit. And on reinstall it might work correctly as something might have gone wrong during first install or later upgrade.
Question 2: You can only do this via adb, either adb over usb, or adb over tcpip. Please do some googling otherwise this will be a very lengthy explanation which others probably already did better.

Thank you for your response surfer63, very interesting indeed seems to be the case here, i'll try to take it into account, i havent seen this happening yet but i havent installed any new apps yet aswell.
I will certainly look into it, but will the adb over usb method work without rooting the device?
Maybe you know how i can enter recovery mode on my headunit, havent tried the reset button yet, but i figure it is needed, i tried all other key combo's but nothing worked so far (capacitive buttons). If i press the reset mini button on my unit what exactly will happen, will it do a factory reset or does that need some extra actions?
I have searched youtube and google but can't seem to find my headunit and there are lots of diffrent methods to get into it with no physical buttons, maybe you know the most used method for these kind of things? Haven't tried anything yet with the reset button though, but i wanna know what it does exactly before i start fidling around with that button.
So I've recently been having alot of issues with my backup camera sticking, needing to reboot to fix it. So I first flashed the rom, issue persisted. I then flashed the simplecan and then flashed the mcu (both the correct files). After the mcu upgrade it rebooted. It has been stuck in a boot loop ever since. I have spent countless hours trying to figure out how to get the unit into recovery, fastboot, maskerom. I've tried tons of button combinations, a keyboard, jumping the Dow pins (suggestion from Sergey firmware), soldering off the org resistor on the som. I figured the mcu was bricked but I'm not 100% as the air conditioning controls and such still work. This thing is really kicking my butt. I have the proper recovery.zip and mcu file I just need someone to point me in the right direction.
