I purchased an Enco B046 Android-powered head unit for my car, and there are some things I'd love to be able to fix, if I could somehow acquire root access. Most importantly, the GPS functionality. Here's what I know about it:
1. It's a Telechips TCC8925
2. It only has one USB port (Female-A), and it appears to be Host-only. Hooking up a Male-A to Male-A cable between it and a PC, the PC doesn't detect anything on the other end. Hooking up an OTG cable between it and another Android device, the Enco B046 tries to mount the other Android as mass storage..
3. It's running ICS (4.0.4)
4. There's no pinout on the board for another USB port, nor any other pins that are giving +5vdc
5. It does have an SD slot and a card in it. It mounts and works fine.
It's relatively similar in size and form to this:
http://www.slatedroid.com/topic/36988-cx-01-cortex-a5/
Since I can't connect to it via USB and control it with ADB, that eliminates all of the ways to root the device that I have come across.
The most important thing that I need to do is to update the framework.jar, as it suffers from an incorrect GetSpeed function that throws off pretty much every GPS application. It's calculating my land speed at 1.852% of the actual speed. I have fixed the error, and repackaged the framework.jar, but to updated it, alas, I need root access.
It's a shot in the dark, but without some sort of physical connectivity, I'm at a loss. Does anyone have any ideas how I might acquire root on this thing, via software only? Or other ideas as to how I might be able to connect to it?
Thanks!
After further examination, the board has one button on it. If I hold it down during bootup, it goes to a black screen, but a red LED light stays on solid on the board. Generally, that light flashes. I'm wondering if that button doesn't enable FWDN, or Fastboot mode. Maybe that's the ticket.
Hi my friend! Any news?

No news yet. I do think I've figured out how to get into FWDN mode, so I should be able to take a complete backup of the NAND, etc. That doesn't do me a whole lot of good, though, since I don't think you can inject something into an FWDN image.
I suppose I could try to recompile it completely from source, but I'm not sure what all drivers are compiled into the current system, and have no experience doing anything of that nature with Android before.
I wish there were a magic "root" apk I could install, and be done with it!

As usual if we push hard enough and make enough noise on the forums we'll get there, if Charles has to refund every paypal customer because the GPS is crap....he'll find a way to get us root, it's as simple as that
Found this, I don't know if it can help but perhaps the guys who are playing with it can help you....

I think the button on the board may actually put it into FWDN mode, but the USB port configuration doesn't seem to allow the board to act in Device-Mode in any way. If you power it on while holding down the button, it seems to do something. The screen shows "NO SIGNAL" which is what would happen if it goes into FWDN mode. But, I can't get anything to communicate with it. It doesn't show up in device manager at all, on multiple PCs.
Looks like for now, our only hope is for someone to create an APK that somehow magically roots the thing. I'll go ahead and hold my breath.
Also Searching

Sure did just rooted my car stereo... had to update the Superuser app and a few others...... next task is to figure out what tweaks to build.prop i need to get all apps in play store.... especially the google apps.
FYI - after applying the update the screen flickered on the boot up. I reset the device (power cycled via the reset button) and then powered it back on and all is good!
I may be able to post some screen shots in a little bit if you like.....
Car stereo..... as in Enco B046 ?
Screenshots.......Enjoy

WHOA!!! That bad boy is $800 now I only payed $378 shipped
For which car was it ? Because 800 is a bit expensive, we're at 450-500 for a BMW unit, look at www.szenco.com
Thanks a lot for the link anyway, I'll try that tonight....

Well, because of you it can be rooted now so the price went up the ceiling
I bought it to use in a 2005 Ford F-150
If you can pay for the gas you can pay 800 for the stereo

This is awesome, thank you very much! Going to try it tonight.
Any luck with build.prop?
Have you guys experienced of the following problems(before rooting)?
-SD Card error message(not related to external microsd)
-Some apps installs but then give a "no sd card present" error
-Google Nav: works for a short while then all you get is "searching for GPS"
Hello everybody,
firstly i wanted to say that i'm very new to this forum, and also my english is not so good (or how we say here in germany: my english is not the yellow from the egg ^^).
So, whats the Problem?
How you can read in the title i'm searching for something, to record a screen. BUT: yeah, of course there are 1000s of tutorials on the net how to record with quite a good framerate, and why do i create this thread when i know that it's already around in the net? Because that's not what i'm searching for. I do not want to record my android screen, but my pc monitor. And because if you use fraps, the video get's really big and you need much more resources to record in good quality, i thought that maybe the smartphone could record what happens on the pc.
How could it work?
Well the first thing i thought of whas the mini-usb to hdmi cable that lays around here anywhere. So maybe you could simply use the hdmi output of the pc and turn the monitor mode this way, that you have the same picture on both "monitors" and the android phone just records what comes out of the cable (in easy, non professional words)
Otherwise i would think of something with the usb cable, for this there must be something installed on the pc of course.
So the first thing i'd like to know from you is that you think if it's possible and of course how it could works.
phone data:
sgs2 i9100
Jellybam 5.2.0
Dorimanx kernel v7.2.9
rooted of course ;D
greetings and thanks in advance.
so there's noone who has any experiences in this topic?
Hiya People I hope somebody can help me!
Im trying to screen record on my android tablet but the only ways I know how to is scree o matic - problem there is it says 'I need to enable JAVA' Which im finding it impossible to enable -does anyone have any suggestions for that?
Second of all I think I know how to do it by ROOTING the tablet but i'm also finding it very difficult to Connect my tablet to Laptop VIA Usb cable (Male to Male) as my laptop doesn't pick anything up. (its not my USB drives as they work well with phones etc...
Someone please help!!!!!!:crying::crying::crying::crying::crying:
Hello. Today I have made terrible mistake when trying to turn on a device in my pc. I have changed the voltage from my source power and my pc has exploded. Luckly, only the power supply has exploded in fact, like all other things are working and I'm typing this now on my pc. However the integrated sound card from my motherboard have stop working, don't get recognized even when I try to uninstall and re-install. I think it have damaged...
Well, this sucks, but while I don't spend a few bucks trying to get a cheap off-board sound card, I was thinking if there are any way to make a android device sounds like a USB offboard sound card. I have searched in web and XDA for a answer, but always I get the solution using wifi. I already get this working, but has a small lag, and this is uncomfortable. Others resolutions always use some kind of kernel change or/and OTG support with the device.
TLDR: Now, this is my question: Someone has managed to send the audio from the PC via USB for a android in a device (like a off-board USB sound card), and this could be possible without kernel changes or OTG? (My Moto E don't support OTG, unfortunately)
PS: Sorry for the long post, I just wanted to share my unlucky story.
Aloha Everyone!
My S9+ screen has broken yet I can tell it's still functioning as my alarms keep going off etc and when I plug into my PC it registers the phone and should be authorized on this pc.
However since I can't use the screen I can't change the debug settings or put it into "file transfer mode".
I see Dr Fone, Droidkit, Phone Rescue etc. but they all seem suspect and suspiciously all want 35$. I don't mind paying if they work however they all seem to require I put it into debugging which once again I can't do with my broken screen.
Is there any open source solution to this? I would like the pictures on the internal SD of course but I need a recording I made with voice record for a meeting I have tonight. This is my priority and I am currently at work and don't have the time to scour forums and all the regular things I would do.
Any help is appreciated! I don't think this post is breaking any rules and if it is I'm sorry. The S9+ mention is specific but only because I need to explain the generation of the phone as it's older.
I know this is an old phone and I pray someone sees this, infinite mahalos for any suggestions or replies in advance!
You Rock!
Is your screen responsive to touch (Even if you can’t see what you are touching)?
I saw you said broken, do you mean physically? Can you see anything on the screen?
Could you use scrcpy?
It has a few small cracks that water got into and fried the screen I believe.
My alarms going off at the proper times, if I touch the buttons it will vibrate in the ways it should etc.
It doesn't seem to be responding to touch however and it is black as in off, no color or light.
I am looking into scrcpy! Thanks, if anyone has any other suggestions that would be much appreciated!
Spcry won't work because I am not in debug mode, or rather never authorized it while I had it unlike all my previous phones. I got bored of homebrew apps and didn't bother doing it on this one.
Not sure there is anything you can do. No PC programs can control, no Bluetooth mice, no nothing.
Damn, you would think there would be a program at this point to bypass everything and grab your files.
Thanks for your help everyone!
If there was, I would be patched right away, and whoever reported it would get thousands of dollars for the report.
im pretty sure you can use a usb c hub with hdmi and usb to plug in a mouse and your phone to a tv
This is late, but questions do NOT belong in the Development section. Also, this post is for a S9+, not an S9.
