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:

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.

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..
-D
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.
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.
Guys,
I'm not even sure where to start with what I'm seeing, but maybe you can help me.
I have had Timur's ROM on my N7 2012 for a couple years. It's been crashing randomly, even though I have few things installed on it, and a good power supply. I took it out of my car and put it on an iPad 2 amp supply, and it still crashed a bunch so I knew I needed to wipe and reinstall. I also wanted to go from 4.2.2 to 5+, which I know takes away a lot of the good features I need (like power on/deep sleep).
I booted into TWRP and wiped my tablet, which appeared to softbrick it (I think I have the usage right from searching). I downloaded the Pure Nexus 6.0.1, CM13, and already had Autodroid ROMs to use. I tried to install Pure through ADB sideload, and got it installed. When I finished and tried to reboot, it said I had no OS. When I rebooted, I got the boot animation, and nothing else.
Long story short, I tried Autodroid and CM13, and using CM13 I got it back going. Unfortunately, every time I try to flash another ROM over it, it will no longer go past the boot screen. With CM13, it boots properly, but doesn't like the gapps pico I tried to install (error message when booted, keeps returning to the same pop up error).
I'm quite sure there's something I'm missing, but I don't know what it is.
Thanks!
Eric
Ok, before anyone goes nuclear on me, I think I better understand what happened. When I got ANYTHING to work, I stopped doing anything. As I understand, it wasn't functioning...it was just in a temporary mode of some sort.
After not being able to get it to work properly, I used this: http://forum.xda-developers.com/showthread.php?t=1781250 to try and restore the system. I followed all the directions, except for using the 5.1.1 version of the ROM, and used the corresponding file name for the zip file used.
After doing so, the bootloader won't go to TWRP, but goes to the pic as seen below. I did reboot the tablet, and after waiting quite a while, the tablet came on, but I don't understand what that picture means.
Thanks!
Eric
Ok...I realized that I lost root. I'm fixing it now. I had read before, but didn't understand what I saw.
Thanks,
Eric

Video of current STATUS "https://youtu.be/GBWbid59f1E"
Current state of my problem -- STUCK in a screen at Drive Screen "an empty modal opens" Also looking for -- OnePlus 5 OxygenOS 4.5.15 rom --
OP5 EUROPE (if this helps to know what kind of phone I got, I know there are some differences in countries, dont know if it happens with OP specifically)
Currently trying to fix this using:
twrp-3.2.1-0
OnePlus5 Oxygen 4.5.15
-----------------------------------------------------------------------------------------------------------------
After reading plenty of other Threads with similar problems, I am clueless of whatelse to do but to exhibit how I disgraced my phone in hopes for somebody to help me.
I know I am 100% guilty of all that happened but I still somehow hope to get help.
Now the proper what happened.
After the purchase of some apps that seemed to encourage me to root my phone from Android Store, to get more features, I decided to give it a go.
So I got myself:
twrp-3.1.1-0
The Rom from Cyanogen
SuperSu v2.79-20
Granted myself access to booting and usb debugging after becoming a developer (granted by the university of tap your phone screen like a monkey smashing buttons, I figure this is even an inside joke from actual Devs)
I followed a tutorial that said next thing was installing twrp and stuffing my rom and my super su in my phone after rooting it, here is when things turn dark after installing the rom.
I saw my data was wiped and thought I had erased its memory, and instead of just putting back the things that I had to install I clicked on another tutorial of a had that had a similar problem (I can provide links later if requested).
In this tutorial the person, said that I should go to Advanced Settings -- WIPE and try and reformat my SYSTEM and my DATA, (heres when I wish my future-self would have come and stopped me because after this it all spiraled into madness)
After this happened my phone said I had no OS, so I didnt know what to do, I had no idea, I tried recovery mode but there was nothing to recover.. , I tried plenty of things really. reformating, downloading more ROMS , when I tried to install any of this Roms a new surprise awaited for me, my phone didnt know it was a OnePlus5 anymore it decided asume a misterious identity now he was " " instead.
I googled this, and a guy had a work around in wich I had to go into the rom and into the META-INF --COM -- google -- android -- updater-script
and inside this very archive delete the script that validated wich phone I had, this solution wouldnt work with any rom I had because they all said "updating the img was unsuccesful" at this point I was asking myself only one thing "WHAT IMAGE?!?!" a second ago there was no OS at all and now there was an image to update?.
I kept trying roms until one worked the stable official version, now I managed to install the rom rebooted, to find that the OS seems to have been installed, but.. when I introduce my pin things begin guetting funny again...
My SIM doesnt seem to be recognized its called "Slot 2" and when I enter the pin it and "SWIPE UP" as the phone suggests it gets stuck at a panel called "Drive".
I am guessing I am having an issue with the drivers but this is only a guess, I really have no Idea how to fix this, I tried to look up if somebody else was strugging with a FREEZE at DRIVE.
but it seems that nobody else fell into the spiral of foolishness I did, please help me find a way into a solution.
When I try to recover from the phone and install from "internal storage" doesnt allows me as there was no such thing.
use codeworkx twrp
Use a Keurig and just breathe
try flashing a twrp recovery. then boot to recovery. then push via adb a recent oneplus rom. then install the rom. then reboot to system and see if it is working.
I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.

If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
