Help. Updated didn't go as planned.

After following this thread for a while and reading up I thought I had a good enough handle on things to update my unit. Apparently I was wrong as my update didn't work. Hopefully someone can shed some light on what went wrong.

My settings before the update:

Android Version 4.1.1

MCU Version 4.2.5-1-10-2101

System Version 2.6.70

DVD Version 2.13.11-hd860mc

I started trying to update to the permroot 2.8.7 by placing the files on my (64gb) sd card. It got stuck on the android logo. It never said "Update Start" or anything else on that screen. Hoping that it was working and not wanting to interrupt it I left it for over half an hour and nothing changed. I tried rebooting and it again got stuck on the android logo again. After reading up some more in this thread I dug up a smaller sd card (16gb the smallest I could find) and tried with that. This time it said "Update start" immediately followed by "Update End" without listing files or anything else on the screen. It stayed stuck on the android logo. Based on what people said worked for them I tried different versions (2.8.6 2.6.70 2.6.60) sometimes it would say "Update Start" but not "Update End" some would say both some would say nothing. I tried updating without an SD card in to factory resest that way. I tried using the physical reset button. Nothing would get me past the android logo.

Is there something else I should try?

Is there something I need to be doing differently?

Do I need a smaller SD card?

Do you need any more info about my device?

Thanks in advance for any help.
[Android Head-Units] shadowmike:
What exact perm root files are you using.

Without a memory card in, hold power and home, should take a few seconds. It may try to boot, then it will reboot and try to restore if you have firmware files in the / cache folder

Have you tried updating to a 2.7.xx system ?

Hello.

I installed version:

4.3.2-1-10-6101

That's almost the same factory, but the most common:

4.2.5-1-10-6101

I compared the two on the next page:

an21u.coldzone.ru

Version: 4.3.2

Revision H / W: 1

Car model: VW

Features: RDS, color, BC6

The chip tuner: TEF662X

Audio Chip: Rohm37534

But the problem remains.

I will install the MCU that you have uploaded to see if it works.

Thanks in advance. A greeting.

I all the files I used were either from the yandex account you created or from the wiki.

I tried holding power and home. How long do I need to hold it? I held it just until boot started but then it stayed stuck on the android logo.

I didn't try a 2.7.xx. First I tried the newest stuff then when that wasn't working I tried the version people had mentioned that fixed things (which were the older 2.6.xx files)

Do you have a recommended version?

I can buy a smaller SD card today to see if that helps. Does brand matter at all?
[Android Head-Units] shadowmike:
The 16 gig should work. I use a 16 gig for all of my updates.

Though it's a crazy 16 gig.

I can only suggest the 2.7.40 that came on my device.

You can try a smaller sd card, but I would format your current one to get that troubleshoot out of the way. Backup your files first.

@shadowmike

I mess up my bluetooth remember when I was asking how to get my bluetooth to work with torque?

I install the bluetooth manager but I could not get torque to work so I deleted the bluetooth manager I install. now my car is not seeing my cell phone.

when I do a scan on my cell I find the CAR KIT and it pairing on my cell but the car BT settings in the car are empty.

what is strange is my old settings are required to pair. also I am running 2.8.7 and the BT don't work, SO I went down to 2.7.29 and the BT works. I then up grade back to 2.8.7 and the BT will not work. I went back to 2.7.29 it work again, then up grade to 2.8.7 stop work

any idea anyone.

What I can say is that bluetooth module is the Achille's heel of my unit, I tried decs of firmware/mcu/bt. apk combinations and sometimes BT initialize well, sometimes it won't start at startup, I must reboot one or two times to have it working.

Still not found any logical reason about this behaviour, maybe it's defective, but at the moment that it start it works 100%.

no it was working fine all the time. I was trying to get torque to work so I install a few BT managers and after they did not I uninstall them after I restart my Bt stop working. so I went down to 2.7.29 and its working again but if I go back to 2.8.7 it will not work

right now I am running 2.7.29 and I may have good new for some or most..

I am running 2.7.29 and I use the files that in the repo to root it "BaiduRoot_2001.apk and CWM Superuser.apk"

2.7.29 does not have the UI warning plus its stable, So I will stay with 2.7.29

I then use the files from the 2.8.6 to upgrade the radio app and all the rest apps.

So I guess I was right, you can just root ur unit and upgrade the apps and launcher, because I haven't notice any change from 2.7.9 other than the launcher

I am ruining 2.7.29 and it has the old widget launcher

Do you have the 2.8.7 launcher I will like to use it on 2.7.29
[Android Head-Units] shadowmike:

I experiment 1st so I rename the radio.apk to radio.apkbak then I copy radio apk from 2.8.6 into the system/app folder restart

and I have the 2.8.6 radio working into 2.7.29 I also did the same with the mp3 player.

the launcher do U just install it like any other app or I have to use root explorer to put it somewhere

I try to put it once on the SD and then install. the launcher did change but when I restart the unit the launcher went back to the old launcher

I will do a small youtume vid to show I am running 2.7.29 with 2.8.6 apps
[Android Head-Units] shadowmike:
That's how I do it. But some times you never know.

As long as the Android version doesn't change the apps should always work from version to version.

The main difference you will see in system updates is functionality, and different settings.

Do you have a copy of 2.7.40? I didn't see one in the file repo and tried searching but because of the periods searching doesn't work to well.

Since I already formatted my 16gb card I'll get new 8gb card to try tonight and see if that works any better.

How long do updates normally take? How long should I let it sit at the android logo before giving up on it? Is there anything else I should be looking for to happen on the screen?

Firmware 2.8.8 is out for anyone who is interested. I might try it out this weekend. I would guess we will have to use the bootloader from the permanent 2.8.7 firmware on our share if we want permanent root.

My guess is you can't change the actual overlay lines though. I would suspect that's something done at the MCU level. The setting/app portion just turns it on/off. I don't believe the video feed ever touches the android side, correct?

For those that might be lurking and deciding on which unit to buy, I would suggest you check out the unit in this thread:

http://xdaforums.com/android/general/4-4-2-kitkat-head-unit-newsmy-carpad-t2865525

While the AN-21U has served me well, it's main disadvantage has always been our lack of bootloader/recovery unlock, source code, etc. While some nice things have been achieved via root, etc, the potential of this device remains largely untapped.

The device I mentioned in the above thread has full source available. While I don't think that source was obtained intentionally by the manufacturer, it is now in the hands of a few developers who are very close to making a source built ROM. Root was quickly obtained, and the recovery/flashing method is not encrypted, so modifying the stock firmwares is already easily accomplished.

I've ordered one myself, and will likely join the development cause as time permits.

Hi new here. Was hoping someone could help me out. I had my unit rooted using the root my an21u method a while ago. I wanted to update to the new version. I updated and now I'm in a loop, I only get to the android screen where you would be able to do the update, and it just stays there.

I'm trying to flash something else on but I can't get it to update (volume knob + home isn't working). Any ideas? :(

My unit has the Ouku front but the specs match this unit perfectly. And the root before went off without a hitch.

Edit:

Figured out that thing I thought was a microphone hole was a reset button, wish there was more documentation of each front plate. Anyways I managed to get it back running again. Think I might tempt fate and try to update again.

are you sure ur unit only has 12 presets? I think mines has 16 presets.

on 2.8.8 (8) on the screen at a time then I can swipe left to get the other 8 presets.
