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.

I have been running my a7 with dexter's mod 1.4 for about 1 1/2 weeks...everything has gone well. This afternoon I turned on the device and it failed to complete boot. The word Android would come up and then nothing. I tried to reboot, reset, but device would do neither...nor would it turn off completely. I kept trying to take it into recovery mode and then after several tries was able to wipe, do update again, and get everything back as before. What would cause this and should I look for this to happen again? deepmagic
My a7 was running well for about a week since it quit...but today when I booted up device, it failed to recognize sd card...same card used for updating to mod 1.4...same card I've been using to listen to my music, etc...but now won't recognize...I've tried two different micro sdhc cards..formatted, reformatted, but device continues to display mount sd card...all else works fine! Does anyone have any new ideas? I can't even reinstall mod since a7 can't read my cards. Thanks for any input that would be helpful. I understand these issues are ongoing for many out there...what to do?

Mine has hung on a black screen on me. Seemed that it didn't fully come out of sleep mode.
I was able to recover by holding the power button for 15 seconds to hard power down. No data loss.

Exact same thing happened to me this morning. Tried to reset - not happening. Hard powered down. Don't have time to try anything else right now. I'm new to the forums and new to android. Wish me luck! I've been loving my A7, and much appreciation to Dexter and all the other knowledgeable hackers/modders/posters.
hey the same thing happened 2 me twice. Once the first day after i got it, since i had only had it for 1 day i wiped it reinstalled dexter's mod 1.41 and it worked. First app i installed was backup root. Now, a week later the exact same thing is happening. This time i dont want to wipe it because of all of the apps i have installed, games ive played etc. Any ideas? Could we just try reinstalling dexter's md without wiping? Or wiping reinstalling and recover from a backup?
Also have you installed busybox? I had just installed it both times before it failed to turn on. Maybe its just coincidence but you never know..

Thanks to anyone who can help! and also thanks Dexter for all your hard work as well as everyone else that has contributed to the elocity, im lovin it! (when it works )
success!!!!
I got it to work! I don't have a permanent fix but if it happens again just boot into recovery and reinstall the dexter's mod update 1.41 and it works again! No wiping required. This isn't a permanent fix but it will work until we find one

Hasn't happened to me (yet) but I didn't upgrade to the newest ROM. I'm still using 1.3and it has been very stable. Only issue I've had was when I tried to use Killswitch to go to sleep mode when the cover is shut (great idea) but it didn't work and froze all except the live wallpaper. Weird.
Good luck, guys.
in the event it does happen to you, you might want to check out my apx thread for reflashing the factory firmware if you can't get your tablet unstuck. theres alternatives if you don't want to get stuck again.
The method you outline seems so complex...way above my abilities, but makes me wish I had followed though on some early programming training opportunities. That was the road not travelled.
okantomi; while i wouldn't encourage others to follow thru with procedures they fear would cause more harm, i would mention that if you google up my nick you'll find i've been able to do much w/ android software and devices while not knowing anything about programming. if i can do it, anyone can. i just wanted some themes for my phone.
i'm just an android hobbyist by night (and when i get a chance during the day), and a computer tech by day. no programming expertise, but i can reasonably reverse engineer and port software and components using simple file managers like ztreewin(trialware).
don't be mistaken that the folks out there providing you solutions necessarily know anything about programming or software development. just how to chef up files at different levels. i understand this doesn't go for everybody.
Thanks for the encouragement. I'm impressed with what you've been able to do. It is also nice to read upbeat comments about the A7. There is something sort of special about a device that you really almost have to build yourself... putting so much into it... biting your fingernails to nubs with each ROM flashing. You don't get as attached to any device that is 100 percent complete right out of the box, though of course there would be a lot less aggravation.
Hello everyone! Everything was working okay till I download some new clockfaces and then uninstalled the one I was displaying. The result is that I now have a blank screen and am unable to select anything.
Is there a way to reset it to the factory settings?
I think I have tried everything without stripping the thing down.
Has anyone got any ideas please?
Thank in advance.
Same problem as this thread (https://forum.xda-developers.com/smartwatch/other-smartwatches/k88h-smart-watch-reset-t3386465) but with IWO 2

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...
tablet specs:
android 8.1.0

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.
Ok so I purchased a android headunit from eBay for my Lexus. Installed it worked great. Then Google stopped working which led me to these threads trying to fix it.
Upon apps I downloaded I managed to find out the device is a Allwinner t3p1 running android 8.1 (was told it was 10). I've tried reaching out to my seller but don't think he was official think it was just a kid that didn't understand it. But he has vanished so no help there. I tried reaching out to all winner with no response.
I managed to do a factory reset and now it's stuck on Android boot logo.
I managed to get some pics before the unit got stuck
Need some assistance on what I need to do to get it working again.
I've attached photos that have the version, MCU, and other info of unit.
