Dynavin ANDROID - Hacking & Development

YOU take full responsibility if you try anything in this thread and ruin your dynavin, so do this at your own risk.

Some Usefull info:

Installing a ROM
Either use the SD card that came with the Dynavin, or downloaded EaseUS, and format a 2 GB card as FAT (FAT16) with 64kb allocation.

1. Unzip the ROM file and copy all the files to the root of the 2 GB SD card that came with the Dynavin
2. Boot up the Dynavin with the SD card
3. Takes about 5 to 10 minutes, and will notify you when it's done
4. Take out the SD card
5. If you're reusing the same SD card, remove all the ROM files from the root before reinserting it

Manually rooting Android 2.2 using z4root:

You can grab the file from XDA at:
http://forum.xda-developers.com/showthread.php?t=833953

Prepare your system for rooting:
Go in to settings and enable USB debugging, and allow non market apps.

1. Copy the z4root.apk file to your SD card
2. Using a file manager, install the z4root app
3. Run the z4root app after install
4. Chose "root permanent"
5. System will reboot (in about 2 or 3 minutes) and you will be rooted (superuser and busybox installed)
6. Now grab busybox installer from the market and install the latest version of busybox

Tweaks & Tips

Better/Faster Clock Sync
These apps will make your clock sync faster, and having the clock sync faster will solve a lot of issues the Droidavyn has.
I was able to get the correct time on the Droidavyn down to about 15-30 seconds (stock it took at least 2 to 3 minutes).

1. TimeZoneFixer - the dynavin has the 2009h version of the database, this will copy over the 2011h version (https://market.android.com/details?i...m9uZWZpeGVyIl0.)
2. ClockSync - setup to sync every 15 minutes; enable local database, and set it to sync on boot (https://market.android.com/details?i...Nsb2NrU3luYyJd)

GPS Configuration file (may help get a faster GPS fix)

1. Copy the gps.conf file onto your sd card.
2. Make sure you go in to settings and enable USB debugging, and allow non market apps.
3. Make sure your date and time are correct (manually), then check the auto update setting.
4. Download root explorer and copy over the gps.conf file to your /system/etc folder (https://market.android.com/details?i...RleHBsb3JlciJd)
5. Get GPS Status and Toolbox (https://market.android.com/details?i...HNzdGF0dXMyIl0.)
   Startup GPS Status and toolbox, reset the AGPS data and download again. Change the settings to download as frequently as possible.

Excellent.....go to it guys!

Just like I have asked im my threads, lets try to keep this thread useful and helpful, so keep opinion and unnecessary comments to a minimum, let the guys who know what they are doing post so that the most useful info stays easy to find.

Here is the link to my dev server - http://jneumann.net/Baldr/

When exams are over in a few days I'll have more time to work on it, but m3evolution's builds are a MUCH better choice at this point in time.

If anyone would like me to add anything to or change anyting in the first post, just let me know. I'll do my best to keep it updated.

Like Jeff said, let's try and keep this useful and helpful.

A site that I have used in the past for tons of info on hacking android of all shapes and sizes is http://forum.xda-developers.com/index.php. Scroll down to the android specific links about mid way down the page. Has anyone tried to load a new boot loader to the Dynavin yet? I won't have mine for a couple of months unless I can generate a spare thousand quickly, but any help I can be on making Android run better will make it all better when I get it.

I think I read that because of the chip that Dynavin uses, there is no "Bootloader" so no CWM or 4ext type interface will be available. The only way to flash is to load the ROM flash files to a SD card and boot.

From my understanding of computing and Android there has to be a bootloader. There is always a "BIOS" (in quotes cause they are called different things depending) its really just a matter of figuring out how to pause the boot process at the boot loader. With cells and tablets normally its holding down a couple of buttons at the same time during power up. Even your DVD player in your house or "smart" TV has a basic input output operating system. The Dynavin system may use a different method such as a signal pin on the rear going high or going low. If I had my hands on one I would run a check list of all of the different buttons and what two/ three button combos I could try and then run through them all. A new boot loader would give so much more functionality to the system.

I've got an email out to Dynavin requesting the info that we need to stop the boot process and load a different boot loader on to it. We will see if they respond.

Do you guys know what files the Timezonefixer.apk changes or adds to the Dynavin? I was thinking of just including those new updated 2011N files to the rom so we dont have to install the Timezonefixer.apk The warning at the bottom of that program stating that the timezonefixer.apk might brick the Dynavin makes me a lil nervous plus it request alot of superuser permissions.

tassi333 maybe you can add this to the first post.

My Dynavin CPU appears to be locked at the default 500 mhz but it is capable of 720mhz max. Anybody brave enough to try to overclock or just run it at its max rating? I tried SetCPU to push it to 720mhz nothing happend maybe I didnt set it up correctly.

If it's anything like the beagleboard, we should leave it at 500Mhz. 600 is doable, but pushing it, 720 results in heat deaths from what I've heard.

SetCPU won't work because it's a custom board, and probably doesn't have any way of modifying the PLL driving the CPU. Besides, this thing already benches near my 1Ghz Samsung Mesmerize. I'm pretty sure RAM is the issue here.

As for the bootloader, we honestly don't need something like clockworkmod. SD card flashing gets us everything we need, albeit all at once. Not to mention the whole no button issue. I think I'd rather just flash via SD card than try to figure out how to wire up some buttons. I already have a USB debugging cable hanging out of my dash that I'm about ready to just cut off.

Nandroid backups however, would be nice...

I would suggest Milestone Overclock. It is built to work specifically for Omap3 processors and is free on the market.

how about TWRP 2.0 Recovery instead of CWM

So a new bootloader would do way more than flashing, besides flashing would still occur from the SD card. I'm not sure what you are referring to "wire up some buttons"? You have buttons on it already to operate it don't you? Sorry all the pics I have seen are for the 99 on the dynavin site. Backups, reset button functions, flashing new skins from bootloader instead of replacing everything. Lots more too. I think its worth it, when I get the 99 ill be trying for sure.

there are no hard buttons for android....its not like a phone, that is where the difficulty lies.

I believe it was discussed at length on the android thread.

Yeah too bad there are no physical buttons, at least a home, back and menu button would've been nice.

Not sure why they settled on Android 2.2 either? Why not go at least 3.x honeycomb, it would've been easier to use since 3.x was designed for a tablet not phone.

Maybe the next release will be the D200 Android 4.x "Ice Cream Sandwhich" with a nice dual core processor (nVidia Tegra maybe?) We'll probably see an announcement a couple months after the D99 is released

What would be awesome is if the entire unit was running Android (radio and nav sides; I guess that would mean only one side )

My unit freezes after two hours of GPS usage, so overclocking is a bad idea. In fact, I'd like to keep my unit cooler in order to avoid these problems.

Thanks for the tip. I tried it out on my unit but it couldnt autodetect the kernel module. But after checking out the dev website for the app it appears its possible but would require some digging to get it to work.

I understand there are many cons to overclocking but if we can get a stable overclock there are many pros too.

If we can get this to work we can also use it to underclock to keep the unit cooler for those that wish to underclock.

Heres the link to the dev website. If anyone knows how to get the frequency and vsel from the kernel please post.

There may not be buttons to operate the android side, but that doesn't mean that while the unit is booting the buttons on the unit won't break the boot cycle and pause it. It does point me in the direction that the radio firmware is probably tied to the boot loader which may cause some headaches. I can only suggest until I can buy my own for disection and hook up a some diagnostic equipment like a protocol analyzer.

Has anyone tried a radio app to run the radio android style. Sprint has one that's great. I know there are others in the market.
