Rock on, thanks for the info.

Yeah, I'm the one who spent the time fixing the GPS speed error in the first place on the "Enco" radio, and releasing it to the public, because Szenco isn't much for support.

I was given a heads-up a while back from the guy who runs Andrive that there was an image that should work on the Enco radios to add bluetooth. I eventually flashed it, and my radio's been in a boot loop for months now. I appreciate that he gave me the heads-up, as helped him out with the GPS speed error, came up with a fix he could implement for the "Enco Shuffle" and spent some time brainstorming with him about some other issues with these radios. However, as soon as I mentioned to him that my radio was in a boot loop and asked if he had any advice, he completely stopped responding to my IMs. I was hoping to work with him to get a dump of all of the partitions, so I could create a plan of action for this system. I'm not sure if he thinks I blame him for the boot loop--I don't, I assumed the risk when flashing the system--I am a bit disappointed that he's avoiding me.
[Android Q&A, Help & Troubleshooting] clearspace:
The Andrive update files seems to have been removed from the Internets! They were posted on a forum somewhere and links to them were posted in this thread a few pages back. Can you tell me more about the "V2.2" file? When I downloaded these files earlier this year only V0.4 and V2.1 were available. About the guy on Andrive. Maybe he would be more accommodating if you (we) were actually owning an Andrive unit (and not Encos, Enways, dynavin and what not)?;):p I would happily offer payment to him if he made these files available for purchase.
[Android Q&A, Help & Troubleshooting] derpderpy:
Not sure where my post took off to, but the difference between 0.4, 2.1 and 2.2 are board revisions. The updates are the same, as far as functionality, but whomever built the android boards that are in the Enco units switched up what kind of flash memory they were using, which changes a few mappings, etc. I have 2.2 archived, but it definitely don't do any Enco users any good.

If I come up with a safe method, would you be willing to create a dump of your system and misc partitions for me? I've determined my bootloader is jacked, which is why I'm stuck in a bootloop, and the part of the update-script in V0.4 that's supposed to rewrite the bootloader nand just errors out for me. So, I plan on booting from disk images on the SD card in a round-about way. I should be able to create an update.zip that does a chroot to a folder on the SD card that has the contents of /boot in it, then exec init from there. I can modify the init.rc to unmount everything then mount disk images as the proper partitions. If I can make this work, I can likely use it to resolve others' permanent boot loops as well.

Sure. But you have to give me some instructions how to do that as I have never done it before. :cool:

Hello.

I have bricked my tcc8925 wirh the wrong firmware. I have the 0.4 version board. I got stuck in an update loop, and I tried to turn it off between updates. When I now start the car player, It just starts the radio part, but no android.

I have read about this pin 13, but I have not found a picture of this, nor either any explanation of witch pin 13 this is.

Is it on the board with the TCC8925 chip? Or the "tablet board" at the back of the screen?

Hello all,

Since 1 week my szenco b046 is bootlloping on the android side.

I get the first android logo, then the 2nd one with thr metallic lighty effect and then it just stays there.

Is there a way to force an update from the SD port or anything ?

The normal radio side works fine and I did not add anything special on the android side before the crash.

Confirmed working! Dead easy too...
[Android Q&A, Help & Troubleshooting] sav_za:
Sorted!

I have found a solution for the storage problem. After a massive amount of googling and trial & error I've eventually stumbled upon a solution.

http://www.slatedroid.com/topic/28710-how-do-you-actually-use-the-nand-flash-memory/

"In system/etc/ is a file called vold.fstab that you need to edit."

dev_mount sdcard /mnt/sdcard auto /devices/platform/AMLOGIC_CARD/card_host/memorycard0

dev_mount flash /mnt/flash auto /devices/virtual/mtd/mtd3/avnftl3

Now for my radio the file looks slightly different, mine's got "sdcard" and "ext_sd". Swap the two, copy the file back onto the radio, set permissions, reboot and voila! Apps complaining about external storage are now working and everything else seems to still be working fine.
[Android Q&A, Help & Troubleshooting] swjpilot:
This app does a slightly better job of fixing your storage issue... I tried your way at one point but had some issue I forget now....

http://goo.gl/fO2QP

As far as the GPS no issues so far there.

I did modify a keyboard layout file for my Logitech diNovo keyboard to make certain keys do Home and other android specific functions.

The attached build.prop will get you full access to the Google PLay but you will have to force stop, clear data and cache from the google play store and play services after you put this file in place.

and lastly the source code for the system is located here.

http://goo.gl/qpnaj

I am playing with it to add support for certain bluetooth dongles, different wireless cards than the one that came with it and maybe a few other USB peripherals.......

My biggest issue I still have is that chrome browser crashes on startup everytime.
[Android Q&A, Help & Troubleshooting] cssvb94:
Guys,

Good job! :victory:

Today I ordered the same system from aliexpress.com.

Do you mind to provide simple guide/steps how to do the rooting.

Do I have to open the device to press that reset button in order to put it in update mode?

Cheers :D
[Android Q&A, Help & Troubleshooting] swjpilot:
No all you have to do is put the zip on the SD card (The one marked GPS on the front) rename it to update.zip and then go to

settings>about Tablet>System updates>External Storage

and voila you are rooted...

Of course i put the typical disclaimer... I am not responsible if your device gets bricked
[Android Q&A, Help & Troubleshooting] sav_za:
Thanks for the tips, that app is pretty much exactly what I was looking for but never came across. I'll give the build.prop a try, it should save me a lot of time and trouble.

I've installed some other navigation apps yesterday and they're working fine except the reported speed is very wrong.

---------- Post added at 07:58 PM ---------- Previous post was at 07:56 PM ----------

I'll definitely be keeping an eye on your posts, USB BT support would be great, especially since you'd then be able to use the Torque app.

---------- Post added at 08:09 PM ---------- Previous post was at 07:58 PM ----------

Quick question, I see in your file you've got:

ro.sf.lcd_density=120

In mine it's 145. Should I keep it at 120 or change it to be the same as my original file?
[Android Q&A, Help & Troubleshooting] swjpilot:
I like the 120 it makes the status bar a little smaller but overall I like the slightly larger screen real estate. There are some bluetooth dongles that are already supported that I have heard of...I found some information about broadcom based USB BT dongles worked out of the box... i have one that should be arriving today and I will let you guys know if it worked and where I got it etc.... (Torque is part of my motivation as well) I also want to port this thing over to JB which I am starting on as well.... who knows if that part will work or not...... wish me luck there.

If you guys are interested i got Google NOW working on the device as well using the Handlebars app

http://goo.gl/zvAKW

Just grab the app... say no to the little search malware thing and follow the instructions of the post I just linked.
[Android Q&A, Help & Troubleshooting] sav_za:
Cool, thanks, I'll play around with the density.

You're very brave, good luck. I had three motivations for buying this radio - Torque, TomTom & TuneIn Radio. 2 out of 3 so far isn't too bad but it would be really awesome if Torque could work. It would be even better if it would work together with WiFi. ;)
[Android Q&A, Help & Troubleshooting] swjpilot:
You can use a standard USB hub to connect multiple devices.... that is how i have both my Logitech Dinovo and wifi dongle attached simultaneously.

Love TuneIn Radio!!! was a huge motivation for me as well.... and google music too......
[Android Q&A, Help & Troubleshooting] cssvb94:
Great and thank you.

A interesting thing for the BMW guys also: I'm software developer and I've got usb i-bus dongle from ebay to be able to re-program my oem nav in my bmw.

Then I decided to make android app to communicate with the ibus.

If OTG USB is accessible from Android then would be great.

Here it is running on my 10" tablet. It's still unfinished.
[Android Q&A, Help & Troubleshooting] sav_za:
Aha, that's good news!! I haven't tried Google Music yet but been using TuneIn Radio on my phone to stream via BT for ages. I started getting tired of having to open TuneIn and Tomtom every time I get in the car, hence the radio. I was extremely disappointed when pretty much nothing worked as expected but now there is hope.
[Android Q&A, Help & Troubleshooting] swjpilot:
There is one USB port on the back of my device that is a USB host... this port can then be split using a standard USB 2.0 hub into at least 4 ports. I have looked at the board and posted pictures of the SOC and i do not see any pinouts for additional USB ports or for a client mode port. So far I have not been able to get mine to talk to a PC directly.

on a side note..... the ROM is deodexed by default which is awesome... bring on themeing. I need another one of these things to keep at my workstation and experiment on continuously...cause once I put this thing in my Truck (hopefully this weekend) my access to it will be greatly diminished! :(
[Android Q&A, Help & Troubleshooting] sav_za:
I can vouch for that - it's been in my car since day one so running from my PC to the car and vice versa stops being fun after the 20th time.
[Android Q&A, Help & Troubleshooting] swjpilot:
Yeah i had a little better idea of what to expect.... but with all the progress i feel like i am making i am starting to feel so much better. I would get SOOOOOOOOOOOOOO much braver if i could find either TWRP Recovery or CWM Recovery to put on this thing.... or at the very least fastboot access! I know the button on the MB puts it into FB mode but still have an access issue.......... but i just had an idea.....HMMMMMMM!
[Android Q&A, Help & Troubleshooting] sav_za:
Yeah, I'm also a lot more positive now. I was really hating it on day one.

I'm also scared of bricking the thing, it's the first Android device I've messed around with so it's all brand new to me.
[Android Q&A, Help & Troubleshooting] swjpilot:
ok I think this unused set of contacts is the OTG USB port...... I am planning on trying to solder a wire onto these and see what I come up with. I do wonder what the part on the back view that says 104 on it is......(not sure when i will get to this)... if anyone else has any input please share!!!!
[Android Q&A, Help & Troubleshooting] cssvb94:
Looks a lot like USB port, and this 140 element could be capacitor.

[Android Q&A, Help & Troubleshooting] sav_za:
Quick question and please excuse my ignorance - if I want to reset my device, do I need to root again afterwards and do I need to "unroot" before I reset?
[Android Q&A, Help & Troubleshooting] swjpilot:
Once root is installed doing a factory reset on the device should not remove it as it is part of the ROM. and no you do not need to unroot before that.

[Android Q&A, Help & Troubleshooting] swjpilot:
Yes...Yes it will! I have been trying to solder onto that port all day.... but my soldering skills suck... it is a USB port cause when I touch wires to the contacts my PC recognizes it for a second but I do not have a stable enough connection for it to register anything. I may try to find someone with better soldering skills than I. My bluetooth dongle should be here tomorrow... i will let everyone know how that goes!
[Android Q&A, Help & Troubleshooting] cssvb94:
I'm glad. I saw OTG connection schematic and also some DIP switches configurations about entering in different boot modes.

What you are soldering onto this connections? USB port or 4-wire cable with female USB port?

[Android Q&A, Help & Troubleshooting] derpderpy:
I wanted to stop back in and say thank you to everyone who has brought us Enco owners to this point. This is fantastic.

If anyone is having the issue with GPS where your ground speed is reported at 1.852x the actual speed, I have created a patched framework.jar to fix the problem. This is dangerous, requires you to be rooted, and can break your radio. You are warned. Custom framework.jar to fix speed being 1.852% faster than normal.

The easiest way to install this is to put it on your microSD card, use ES File Explorer, mount the system as read/write, go to your microSD card, long press the new framework.jar and hit "copy." Then, go to /system/framework and long press framework.jar to rename it to framework.jar.old. Then, press the "paste" button at the top. Exit out of ES File Explorer. Open it back up, and verify the new framework.jar is in /system/framework. Reboot.

If it's not there, and you reboot, you're hosed. At least, for a little while.

I received a message on another board today that said, if you short Pin 13 (of the pins that connect the Android board to the radio) out to ground on bootup, it will force it to auto-apply an update.zip from the microSD card slot. They claim they have used this to unbrick one of these units.

For the Enco B046 running Android 4.0.4, here's an update.zip I was sent by Enco that has a good portion, if not all of the system install on it:

https://www.dropbox.com/s/kujmez4bt6ohu6o/update.zip

If your unit's bricked or bootlooped, shorting Pin 13 to ground, with this on your microSD card may very well bring it back from the dead. Not the case, though, if you're running 2.3.x. This will brick your unit, and brick it good.
[Android Q&A, Help & Troubleshooting] sav_za:
Excellent, thanks - mine's got the ground speed problem so I'll try your updated .jar file.

I'm a little bit worried about the update.zip though - my radio seems to be exactly the same as the B046 although it's unbranded and very generic. Have you tried the update on yours? I really would like a non-hacked solution to the internal memory issue and this seems to be exactly what I was looking and hoping for.

---------- Post added at 08:31 AM ---------- Previous post was at 08:30 AM ----------

Oh yes and then the obligatory n00b question - do I need to unroot before updating and re-root afterwards, or can I just go ahead as is?

Looks like I've got a bit of a problem.

I've installed the Enco update - no problems there, except once booted up it immediately gives an error "Unfortunately Google framework services has stopped" and you can't click on the okay button. Any idea how to get past this?
[Android Q&A, Help & Troubleshooting] derpderpy:
I'm not sure about not being able to click on it... But you'll need to find a way to clear the data for the Google Services Framework app to get that popup to go away.

If the touchscreen driver is not loading for some reason, I've had good luck with using a USB mouse. I had a startup application running once that needed clicked on immediately on boot-up, and the touchscreen driver had yet to load. This might be the case there.

Edit: Also, that "update.zip" from Enco is not really an "Update." It doesn't fix anything, so...applying it wouldn't have gotten you anything. :( And no, you don't need to unroot to apply an update.zip. That particular one will unroot you, though...

What's the "internal memory" issue you're having?

So yeah, hook up a USB mouse, see if you can click on it to get it to go away...then clear the data for the Google Services Framework app.
[Android Q&A, Help & Troubleshooting] sav_za:

[Android Q&A, Help & Troubleshooting] derpderpy:
I'm worried that your touch screen requires a different driver than the b046. When you applied that update.zip it overwrote essentially your entire system partition, and with it, libinput.so that was probably custom to your particular radio.

I can't help but ask, but why in the hell did you apply that Enco update.zip that I posted for fixing boot looped / bricked units?
