Hi All,
New guy to the forum, but have been led here multiple times looking for answers. Typically I find them but I'm stuck on this one.
I have an AVIN 5.1.1 9" Navigation Headunit and I am stuck [during/after?] bootup with a screen that says
"Android is Starting"
"Optimizing App 1 of 1"
I've googled for a solution and it says I need to wipe the cache by booting into recovery, which leads me to a new problem--I don't know the combination to get into recovery. I've contacted AVIN, and they have responded, but with just solutions from this forum already--and not directly to the particular headunit.
I can't post pictures or links yet since I'm a new member but it looks like the 6.0 unit of the first hit when you google "e46 9 inch avin"
It has ONE hard button (RST) in the lower left above the MIC. If you press the RST button, the softbuttons light up. If you hold the RST button (even for a minute long) nothing happens until you let go of the RST button. It appears that pressing the RST button removes power from the unit and power is not returned until the RST button is depressed. During boot up, I can press the power button, but it appears that it just shuts off the LCD. I've tried holding the power button down, but nothing also happens.
I'm at a loss and so I'm trusting that the experts on this forum can help.
**SOLUTION FOUND**
using an external usb keyboard, I connected to one of the USB ports.
During boot up, I repeatedly pressed "alt+print screen+e" (no quotes).
It eventually got to recovery boot but there was no way for me to move/select options
I repeatedly pressed "alt+print screen+e" (no quotes) again
keyboard arrows and "enter" works
I know it sounds hokey so I'm not really sure on the details of how everything worked out so if anyone has insight, I would appreciate it.
Thanks!

Thought I would share my experience with this PITA tablet.
Just spent a few days scratching my head trying to factory reset a Lexibook Barbie MFC190BBEN model Android tablet.
It belongs to a 7 year old girl who put a password lock on it for some reason then forgot her password (much to her Mum's annoyance).
The Lexibook support site suggests going into settings and selecting factory reset.
Obviously this cannot be done as the tablet is locked so their next suggestion is to send it back for 'out of warranty' repair!
Some serious googling got me as far as recovery mode (sort of) which involves the reset button being pressed with a paperclip whilst pressing the power button and volume up at the same time whilst connected to a pc via usb.
This gets you a blank tablet screen, adb access but no fastboot and the adb is very limited and stops responding to simple commands.
It uses a Rockchip processor but most of the drivers do not give a stable connection.
After lots of trying to get stable connections so I can push a custom recovery (or get anything at all to talk to the damn tablet) I found that if you disonnect the usb cable and reset the tablet with the reset button you need to hold BOTH volume buttons then press the power button for a couple of seconds..keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
From here I reconnected to the pc and adb could now see a device in recovery mode but with a serial of 0123456789ABCDEF
Still no joy with any adb commands....
Just a few reboots to blank screen again with no adb.
So I reset again and held the two volume buttons to get back to the Android with red exclamation mark again.
Some more googling found a different type of Rockchip based tablet that suggested NOW pressing the power button and volume up quickly..........
Well it turns out this tablet DOES have its own recovery!!!
No amount of googling told me this!!
So after days of messing about with drivers and button presses it turns out it is a simple task to reset from recovery.
You use the volume keys to choose from the minimal options in the recovery menu and use power to select.
Due to the amount of googling I did with no answers that worked (or even came close to an answer) I thought I would share this in the hope it would save someone else from pulling their hair out and keep their child happy!
[emoji1]
you're legend, mate ... I've been trying to put google services and youtube on it for ages. Now it seems it can be done!
No mater how i press the buttons the android robot never appears just the normal start screen please describe the key pressing combination again
Press the reset button with a paperclip whilst you hold BOTH volume buttons then press the power button for a couple of seconds.
Keep holding the volume buttons and you should get the Android robot with a red exclamation mark.
NOW press the power button and volume up quickly..
This should get you into 'recovery'
Thank you. I ll give it a go. Do you know who makes the barbie tablet? I would like to get inttouch with them if it doesn't work.
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks

Good day !
Does anybody now how to get into recovery mode on an Xtrons HU? I tried every combination I could find and I've already been in there but can't remember how I got there. Xtrons support is horrible. They just sent me a video showing a factory reset procedure when I asked for the combination.
I have that one:

You installed malaysk new ROM for our MTCD units via the settings menu or another ROM?
malaysk rom
1. downloaded his rar file
2. unrar
3. copy .img file (dupdate.img) to my sdcard for maps
4. in settings clicked check update (rom is installing from recovery after auto reboot)
btw. Have one problem (i think that its problem with I cant wipe data and cache) u can find it in malaysk thread (last my post).
I have an Xtrons HU as well. I'm not sure the exact buttons to press to get into recovery, but I have done it, so it's possible. Try holding down power button until it totally powers off, then keep holding it until it starts to reboot, eventually you might get in.
On my Xtrons, it doesn't like dupdate.img name, and preferes update.img... but for whatever reason, it gets an error during flashing malaysk's rom, and reboots back to stock rom. I need to look more into it... it seems like it is flashing rom, but at some point an error flashes by too fast to read. I only tried it once so far, will again when I get more time to play.
On my unit, I tried the combo power/reset without any success. Before I read up on this, I did however get into recovery once by accident with just the power button. So after playing around with this more, I can get into recovery consistently doing this:
1) Hold power button until unit turns off and (on my unit) light flashes.
2) Let go and then press the power button again. This somehow shuts off the unit since it would normally just reboot after releasing the button it seems.
3) Press the power button again to turn it on. It should hopefully go into recovery.
I have no idea if this works on other units, but I have not seen a description of this in any of the posts/videos I have seen.

same to me. XTRONS HU, got into recovery by the same method but then, cannot flash. The unit is a GS.
Did you make any progress?
da_anton, did you ever get into recovery mode? I have the Xtrons PF75ATTA which looks the same as yours. After changing the /system directory to read write and adding 3 lines to the build.prop file. The unit only showed the car navigation lollipop screen and the android/car logo.
I have tried almost every combination of power and reset button. How did you do it in the end?
Thanks

Yes I managed to do it. First I would recommend you have a really silent place. You can hear some very quiet sounds at different stages. At least I could.
I managed it that way:
press the power button till the unit is off. I can hear a sound like a "plop". But very quiet. That is my indicator that the unit is off now
release the button. You should now hear another quiet "plop" when the unit is turning on again.
wait maybe 1sec or even more to press and hold the power button again.
the unit now enters recovery
It took me a while to got it working so you have to try it a couple of times.
Thanks, I managed to do it, took me about 20 minutes. I have to say I couldn't hear the noises you were referring to but just knowing the process worked only on timing and the power button narrowed down the possibilities. Thanks again
Xtrons TD696AS recovery mode buttons

It worked on a Xtrons PB76FSFAP-S.
Thanks.
Just installed Oreo on my px5 Xtrons unit. (Mine doesn't have physical buttons minus the reset button).
From any point...hold the reset button for 25 seconds, let go of it...when you see the boot animation press the reset button again (not hold).
You will have to use the reset button as the method for going down through the menu...then hold reset button for it to choose the item.
Worked for me.

Xtrons PB7646BAP Recovery
On the Xtrons PB7646BAP:
I tried everything mentioned in this thread. Nothing worked because my unit does not flash lights or make a "plop" sound. As long as the the car ACC is on, the lights on the unit are on. There is, however, one way I can tell if the unit is on or off after pressing the power button -- by the hissing sound from the speakers.
1. Hold power button down until you no longer hear speakers hissing. Then release button.
2. Not fast, and not too slow: Press then release the button. Then press and release a second time.
3. Unit should come up in recovery. If it doesn't, repeat above.
This sometimes doesn't work. Sometimes because I press too quickly or too slowly. You will have to do it a few times to get the feel of the rhythm you should use.
I have bought this 5.1.1 MTCD unit,but i cant get into recovery.

The seller is no good. Only problems with him. I am in dispute with him becouse the screen is cut of almost 1cm at the botom.Ifvyou have any other seguestion i am all ears.
I wrote this in another thread, but you can try this method.
1) Hold power button to turn it off (about 5-10 seconds).
2) Let go and shortly afterward (1-2 seconds) hit the power button again. This should keep the unit off and prevent it from automatically restarting.
3) You can then hit the power button again to turn it on, and it should go into recovery

If your unit is anything like mine, the rst (reset) button does nothing to get you into recovery. The post by vnamee (http://forum.xda-developers.com/showpost.php?p=67552738&postcount=6) works for me. My unit does not have a recessed power button, it's just the volume knob.
Also, ignore step 3.

First it is wery important,to turn on the lights that you see what is hapenning on the unit. Then press and hold the reset button until the unit shuts off and the lights start blinking. Now the hard part. When the lights blink relise the reset button and when the lights go of pres the reset button.the screen will shut off then press the reset button once more and the unit wil go in to recovery.

After many attempts its works thanks.
To save thread space: (I came across this when I wanted to get into recovery mode but it didn't have my info)
I have a Joying RK3188 2-DIN 1024*600 unit. It has a power switch on the side (push the volume dial) and a res button recessed in a paperclip hole.
You don't actually need to use the RES although perhaps that's another way to do it.
To get into recovery mode hold down power. After ten seconds you'll see backlit keys blink three times quickly. Continue to hold the power key for three more seconds (I counted 1 Mississippi. etc because it's a little tricky there) Then release power and press it again normally a single time. Don't hold it this time.
Wait for the recovery mode to come up. If you see the joying or car icon you've booted too far and you need to retry. The three seconds after the blink seemed to be the key to it.
Before your flash I would practice rebooting and getting into recovery a few times so you know you've got it down in case something goes wrong.
this worked for me as well on my unit for chevy cruze. I just had to put my key on accessory. then 10 secs , 3 more seconds then push power one time.
I have a HotAudio MTCD unit and this has worked for me everytime.
Turn on your lights so that the hard key lights are on. Hold the power button for approx 10 sec until you see all of the buttons flash 3 times. Keep holding the power button for approx 3 more seconds, then release and immediately just press and release it again once. It will then boot right into recovery.
I have no idea why they made them so complicated to get into recovery mode with the 5.1.1 versions. All the old 4.4 versions it was simple as reset+power, let go of reset and hold power button. These new ones are much more tricky and you have to get the timing just right to get it into recovery. Usually takes many attempts for me to finally get it into recovery mode because I do it so rarely.

How to enter into recovery?
Hi, I was trying to root my tab using Brk's Toolkit 8.0
But first, I had to go in APX mod. So I truned the pad off, pressed "Vol up" + "Start" but the tab just booted normally. I did it like 3 times and it always did the same thing.
So I figured I could test holding "Vol. Down" instead of "Vol. Up" while the tab was not booted but plugged to my PC.
The screen flashed, but the tablet didn't start. Instead, it turned black then showed the charging logo.
I tried again. Same flash. But this time the screen went black and nothing responds now. The screen is forever black.
How could this happen ? I know a device can turn into a brick after installing a ROM, but I didn't installed it yet...
Thanks for your insight
EDIT : Okay I feel super dumb but to be honest I didn't find this information elsewhere on the internet so I'm gonna share it :
After contacting Asus' support, they told me to maintain the POWER button for approx. 30 sec, then charging the device again.
Hope this could help someone
