"Unfortunately disc has stop" - head unit stuck - Android Head-Units

Hi guys,
I have installed Unbranded 6.2" double DIN Android 4.1 AN-21 U in my car. For the first two years it was running fine, but then one day an error showed up on the screen saying ""Unfortunately disc has stop". Trying to press OK will make the message disappear for half a second and then it comes back in an infinite loop. Basically this means the system is stuck and I can't do anything with it.
What I already tried:
1. reseting numerous times using reset button
2. shutting down (including disconnecting power) and power back on
3. trying to install a new firmware with recovery screen - failed (for some reason it seams that something is ****ed up with this screen too)
I'm out of ideas, and I think replacing the unit, but I feel like it a shame to throw it away just because of this error message that screwed the all unit.
here is a link for a video showing the issue: youtube.com/watch?v=9POiSlFQmrY&feature=youtu.be
any suggestions would be apretiated

Did you found any solution?
Did you found a solution? What does this error means anyway, the same happend to me

i didnt flash recovery yet, though i can access the files via usb when its locked at lock screen, so im going to try adb push
Good move
Or you can always toss a full stock ROM image on microSD and flash without custom recovery.

Not sure - never done any full package flashes, only update packages. Pretty sure I've seen a bunch of them around these fourms.
Best of luck - hope you don't have a dead tab.

so far it seems i do, tried a update, and still does the same thing
it would be fine if i didnt have a custom boost animation in the system/media
i still have 12 more days warrenty.
is there a way to delete it via computer?
not sure if anyone knew about the hard reset, i contacted acer and played dumb, though i told them what happened.
i was instructed to
Power down the device
hold Vol Up + Power for 3 sec
continue holding Vol up, and keep switch the screen lock back and forth until "erasing cache" comes up on the acer screen
at which point you stop and let it run its course.
said it would take 30 minutes. i fell asleep, 2hrs later i checked it, still same. recontacted acer, another tech said to do the default hard restart with the push pin
worked like a charm
in process of rooting, installing CWM and making backup lol

Did you get it from a local retail location? If so, I would just march back there with my receipt and not give too many details - i was working on a picture and it broke and I have no idea what is wrong, etc - they should just give you a new one.
Have you tried clearing the cache? There is a combo with holding power / volume up when booting and using the rotation lock switch, not quite sure how it is done but i think you just hold both and flip the switch like mad - totally sure I have seen the process posted here somewhere.
If you got it via online order, you still should be able to just return it.
Or call acer - they might be able to work some magic.
Best of luck, hope you get it going or at least get a new one. Really sounds like you have a defective unit, I rooted mine the day after I bought it, have had it for nearly two months and multiple rootings/unrootings/rom flashes and have had no issues at all.

[Q] Desperate Cry for Help :(

Heya XDA - I have no idea WTF happened to my tab. Received notification of a OTA upgrade yesterday, taking me to one of the most recent 3.1 builds (.10 if I remember) - this morning woke up to another OTA update message offering me to go to .11 - accepted, downloaded, tablet hung up during the OTA process.
Now here's where it gets tricky. No matter what I do, when powering up my tablet I get the "Power Off - Shutting down" screen, and a endless spinning circle as the tablet claims to be shutting down. I cannot access any part of the system - all on screen commands are dead, except for the Settings icon in the lower right hand corner - i can click it, enter settings - but the moment I try to select a catagory or change any setting, the system goes right back to the "Power off - Shutting down" screen.
I am way outside the 30 days I can get a trade in - really don't want to have to mail this thing off to Acer.
Here's what I have tried:
One of Vache's full ROM images for my Region - flashed via power and vol process- fails about 1/4 of the way through.
Clearing cache/data - managed to get the vol/power+rotation lock combo going that clears cache and data. Still cannot boot - once I power on no matter what I do I get the "Power Off - Shutting Down" screen.
Tried to do the factory reset via USB keyboard + "Home"??? button? Heard mention this opens up a menu of some sort that I can factory reset from, I have two different USB keyboards and cannot manage to make this happen. Anyone able to explain this? Can this help me?
What's so weird about this - once I power up, I get the "Power Off - Shutting Down" screen no matter what I do. During this time, my battery shows up as %15 - this a500 has been on the charger for hours and hours, overnight last night, was 100% this morning before I applied the OTA update. Even with tablet plugged in, the battery shows as only 15%. What's even weirder - with tablet power off and plugged in, I do not get the red or blue charging light from the power button.
Totally freaking out here, no idea what to do. Anyone able to help?
Edit: When trying to manually flash a update.zip - I am getting the Clockwork Mod (I think?) flash screen - a green droid guy with gears turning. This fails about half way through. I have installed ClockWorkMod before this problem - but cannot enter the clockwork menu by the normal vol/power combo - I am so confused
Edit again: From browsing other posts - seems I am not the only one with this problem. The most recent OTA update failed, every single reboot since then is useless - all I can get is the "Shutting Down.." screen. Trying yet another update.zip via MicroSD to see if I can actually restore my tablet
Edit Yet once more (Problem Resolved!) - no idea how - but after a lot of searching I found a full package with build number 4.010.40_COM_GEN1 - this update.zip flashed with no problems, and my Iconcia is UNBRICKED! Sorry for the panic, everyone
OTA .13 Failure
I have the same problem, but got there by a different path. After many attempts to upgrade to .11 from .7, I downloaded the full file .02 to .11, decrypted and moved update.zip into the external sd card. Used the power / vol- combination and the update to version .11 went on without a hitch. Shortly after that, I received a notice that .13 OTA was available. It appeared to install without a hitch but after it rebooted (automatically) the tablet came back and immediately displayed the never ending Power Off screen described above. I would add that a two gears with a belt icon is sitting in the top left corner and "Android System" is noted beside that icon. I have tried every trick I have found in the forums to fix this:
1. Removed the SD card and shut down the tablet
2. Used power / vol- with portrait rotation lock turned on
3. Put the SD Card (with the .11 update.zip file ) back in and tried 1 and 2 again (no change: never ending power Off)
4. Tried power / vol+ with rotation lock. Saw the cach clear and looked very promising. Came back up with the rotating gears guy, but still went back to Power Off.
As soon as the power button is pressed the power icon goes red and stays there. Looks like the .13 update fools the device into thinking the battery is dean and it tries to shut down but never completes the cycle.

For sure - sorry about the delay on that, was just so excited to be unbricked after a day of futile effort, I needed a break.
Anyway - here's what I have figured out. Somehow during the ota update I received this morning something failed - the tablet rebooted, and regardless of what I did the moment I booted up I would get the powering down notification. System access was not possible. This was on a 100% stock official 3.1 version - even unrooted before letting the update run.
Tried one of the full ROMS from Vache's thread in the dev section, as well as a bunch of other backup images I was able to find. Every single one failed at about 25%.
After a lot of fail - I gave this thread a try:
http://forum.xda-developers.com/showthread.php?t=1187578
"Bricked Tablet...help!"
I used the link on the bottom of page one - the unencrypted update.zip user kjy2010 was kind enough to upload - here is the direct link - http://www.multiupload.com/WCT2FYLMQC
This one worked - put on MicroSD card and flashed via vol/power method - result - 4.10.40_COM_GEN1 - and I am unbricked! Iconiaroot 1.3 worked for getting root after install - slowing getting my tab back to normal now

[Q] My phone is dead on stock...(due to rooting/unlocked failure?) Please help!

Hello XDAers,
I am a real noob at rooting or android-related, and a true one voided of any knowledge regarding anything IT- related.
So dear veterans, please go easy on me.
Due to my prior success of rooting and flashing my Nexus 4 successfully a few months back with no issues, I decided to give it a try to flash a custom ROM for my dad's LG Optimus L7 - which seemed an easy task compared to configuring my Nexus 4 - since there was no need for inputting any command lines or any dealing with the abd (using the easy shortcut, that is).
So, I followed the guide here: http://forum.xda-developers.com/showthread.php?t=1906133 ...
I first factory resettled the phone because it was bloated, then applied the "RunMe.bat" from the "What you desire!" folder. (Everything was already backed-up beforehand.) But the process didn't success until I've retried again and again by re-plugging the USB in because the application/PC couldn't detect the phone. In the same time, I was running KDZ_FW_UPD.exe in the background, so unexpectedly for me the phone shut itself and pushed itself to a vividly green emergency screen, then in a few seconds switched back to a screen of purple-white-blue glitches. I had to close KDZ_FW_UPD.exe without knowing what quite happened since it seemed to be the cause and restarted the process with RunMe.bat.
I didn't manage to "Restore" it first due to the fact that the phone stopped responding due to a lag asking for an encryption key. It was lagging so hard and I had to close the cmd around 5 tries while it was processing, but succeeded later on.
And then, to verify whether I've actually suceeded in rooting L7, I installed Root Checker from the Play Store. And again, for the first few tries the program froze on screen for a long period of time due to "system performance", but after rebooting and restarting the app a few times again, the ROOTING proves to be a success. Just to be sure, around this time I've reloaded KDZ_FW_UPD.exe and it suceeded.
So I went to install CWM and ES. CWM for recovery boot and ES for removing pre-installed system apps as the phone was lagging so badly. I've downloaded the CWM restoring(something like ~6.0.28?) first and tried fastbooting immediately right after, but instead of getting the fastboot menu I got a screen emptied in black with these words:
[5020] "Secure booting error"
[5020] "Cause: boot certification verify"
No hard keys could do anything on the presumed "fastboot", and so I had to hard boot again. I thought that it might be due to the lack of memory(checked on ES later on that it was 310~MB/2GB), and so I've used ES to uninstall a lot of system apps which I deemed uneccessary. So I've Googled a bit and it became apparent to me that that I've didn't unlock the device properly, so lurked around and found a file called L7CWM that is supposedly to resolve my problem, but I presume that it's the CWM recovery image that I've installed. So in the end, I didn't bother with it but kept it on tab just in case.
I repeated the same process with CWM again, but this time, the screen was joined with all kinds of flowery glitches. Restarted the device, and it went only downhill: now the Home launcher stayed all pitch black and nothing appeared. I waited a few minutes, but nothing there until the notification bar appeared. The home screen is apparently dead, and so are the menu keys. Switched to Nova Launcher(installed it just in case Home Launcher fails), and still dead. I couldn't access using any of the menu keys and had unusable launchers.
Hopefully I could still access to the settings from my status bar, but when I did, it started crashing immediately.
I've repeated the attempt a few times after restarting the device a few times, but nothing helped. It only got worse that the when the launcher did SEEM to work. It only showed the wallpaper without showing any of the icons/apps. And crashes again.
I could still access to the App menu via the settings, but couldn't open any of them and when I tried to uninstall them, the screen frozes immediately right after I gain access to the page (white page though) and gain this message: "Unfortunately Package Uninstaller Stopped!"
Then I convinced myself that the only thing I could do at the time was to factory reset the phone and then everything would go alright since I've just had to restore the system apps.
But then the black screen of death came right along with it:
"Secure booting error"
It seems that I'm out of luck... ... But just to check if I'm still left with resorts, I've downloaded the L7CWM file online...
... ...but it still didn't help.
So now I'm being left with no other choices other than asking for help. I never really understand what KDZ_FW_UPD.exe does since I had the LG Driver already before installing it, which I presume was for updating the phone to a newer or older version. And too complex tech articles are kind of alien for me.
EDIT(1 hour later): Okay, now I figured out the reason why L7CWM didn't work was because I didn't extract it to the right folder (after double checked via notepad that I was supposed to directly put it into the C:\ drive). Now it worked(?), but then it didn't.
After launching Flash_Bootloader.bat:
This message now appeared on the L7:
"Sorry!"
"SuperSU is not responding.
Would you like to close it?"
"Wait - Report - Close"
and a few minutes later
"Sorry!"
"Unfortunately, SuperSU has stopped."
"Report - OK"
Now I think the bugs till now happened was due to the fact that I've deleted a file that was required for me to launch apps... Now I just need the right fix.
After 5 minutes of screen inactivity the phone restarted by itself, kind of creepy... ...
Flash_Recovery.bat did nothing.
Reboot2Recovery.bat made it reboot but still struck on the same menu.
Nothing seems to be effective via the phone anymore, seems like I have to rely on abd but then again I don't know how... ... My dad is also f*cking pissed off ^ ^;...

I think that I explained the logs pretty precisely in case I missed something... I'll be very very very very very very thankful if someone could tell me what has caused my phone to fail though.
For references, here are the phone's specifications:

Android version: 4.0.3 (Stock)

If I don't get the phone fixed to being usable soon I think that I will get butchered real hard... ... Preferably needs a step-by-step guide made for toddlers... ...
remove the battery for 10 seconds,put it back pres VOL+ and VOL - same time and than press the power button.when you feel a vibration press for many times the button wich is down in right,try for many times and maybe it will working :}

[HELP] Stuck In Factory Mode - Loop

Hey Guys,
I have a dead phone(kind of). All it displays is
"Have been in Factory Mode. long press power button and Normal boot"
And in very tiny font, there is a line saying
"=>Tool DL Image Load Fail!"
This stays for a few seconds then it turns off, and repeat, again the same this comes up on the screen.
What I have tried:
1) Flash the stock ROM using SP Flash Tools several times
2) Cleaned the power button from the inside a bit, because some thread said there might be a sticky button.
Flashing with SP Flash Tools shows that the flash is successful, but it didn't help.
EDIT: Now it displays something as "eFuse blow: Success". Damn!

Hey, Thank you for replying.
Have tried that method, its just the same thing, but now it is not displaying that tiny line.
Now it goes into the factory mode and shows some options in Chinese. And it stays there till i select something.
The last option, i know is "Reboot To Phone" (Via Google Translate).
When i select that option it goes back into the Factory mode again.

Make sure volume + button is not pressed.
During boot can you boot in to stock recovery,
press POWER BUTTON + VOLUME UP + VOLUME DOWN until Lenovo logo appear, then continue press VOLUME UP + VOLUME DOWN
Thanks all. I somehow got it to work... and now my phone is all good.
As crazylife told, there was some hardware issue. Apparently, there was a tini-tiny bit of a circuit which, due to water allegedly, got short. I had it cleaned by some local phone shop.( He also claimed that the phone work anyway ,though). After that i flashed the stock rom, and it worked.
And btw, how do i mark the thread solved?

I had a problem with the Motherboard due to water getting in, and apparently it caused a short-circuit near the power button module. Actually speaking, I was really dissatisfied with the kind of service the Lenovo guys give to its customers, because first they told me that they will clean, and claimed that the board must be changed. The only thing which needed to be done in my phone was to clean that part of the board with White Petrol(you can ask the local mobile shop guys, they will have it, but just be careful). That solved my problem. And thanks to few threads, i got it working.
P.S: I am from Hyderabad, so had it solved here in a local shop.
Hi, Thanks for your reply. Was able to come out of that situation after 3 days, but had left my mobile with the local service center for 2 days (At the time, when i took my mobile from service center, my mobile was not working, was informed that the mobile is dead) I thought of giving a last try and plugged in the charger on 3rd day it started working . My mobile had a new problem display was broken (from inside) and speakers were not working, when i asked that guy his reply was " how can i know, your mobile was dead, when u brought in hear, my job was to fix it, why will i break it?" though my mobile was back to normal I had to pay a huge price of display and speakers. Hope everyone got to know the take away from my story. Crazy world; lesson learnt.
The same is happening to me!
And my phone keeps vibrating, also I don't know how to select one of those Chinese options, can you please help me sir?

Hey!
My phone had some water damage issue, hence the loop. Opened the phone and cleaned it a bit. Yours might be different problem, try flashing stock firmware, or going into fastboot mode and flashing recovery. Currently don't have this phone so can't help that much.

Oh. Yes my phone too got wet in rain. I went to some shop and they helped me out. But thanks to you I realize that it was repairable and that too without loosing any data. Thanks so much for saving my thousands of ruppees that'd have been wasted to get a new phone. Also yes this model in general is pretty old so I can understand that most of the people don't use it anymore. Again thank you very much for saving all the stuff I had on this phone and the money. ??

Help - Unit on loop...

Hi
I recently bought a Joying UMS01N2 - 2GB 7" Single Din unit... I had previously posted about recommended upgrades, and was successful in doing some basic mods...
I changed the boot logo to a custom , and was then playing around with the bootanimation.zip file to get a custom boot animation (duh)... however, I may have messed something up because now the unit starts, shows the custom boot logo, and then goes to a lit black screen - almost as if in an endless loop... it will not load onto the launcher/app and stays as a black lit screen... I have tried to recover by restarting, and long/short pressing the PWR and RST buttons, but nothing is allowing a reboot/recovery...
Any advise?
I am running Android 6 as per the latest factory ROM (unit received in August) - not updated in Sep to recent update posted on the joying page
Thanks!
I would try to make a "blind" reflashing by attaching flash drive with latest FW.
How exactly is that done? Thanks in advance
Just connect flash drive containing unzipped FW files. Optionally do a soft reset with a toothpick into RST hole. Then wait. Hopefuly reflashing can wipe those boot animations for good (which I am not quite sure of).
As to me, I can not see any point in installing boot animations which under normal conditions one is not going to see on his/her HU screen ever. Only if something wrong happens and some sort of reset performed. Good reminder would be to me what a "beginner" I am
*Needless to say that USB flash drive should be error free irrespective of formatting option.
Would you not see the bootanimation every time the car is started? I say every time since I will probably only drive once a week (weekend toy) and I believe the Joying unit shuts down within 3 days of going into standby...
I will try to reflash using a USB... will post back if I need any further help... Thanks!
It worked!! Thanks!!!
I was able to reflash with a soft boot using the Sep 1 firmware... all my old apps are still there, but I will test them out later... for now the only issue I have is none of my left panel buttons on the screen are working anymore? I have a single din detachable screen with a column of buttons on the left side (power, home, nav, and volume)... and none of them respond to touch?? Is there a setting I need to adjust for this?
There is in settings - something like MCU HW buttons (do not remember exactly, may not contain "HW", but does contain "MCU" and "button"). Should work.
