Hey folks, I've been trying to get the Arduino Mega ADK to work with two of my devices and so far I'm been totally unsuccessful. Both my Nexus S and Nexus 7 seem to do nothing with connected to the Mega ADK.
So, here are the details and hopefully someone can help out.
First off, I'm experienced with Arduinos and µCs. I'm 100% sure that I've correctly compiled and flashed the demo sketch onto the ADK. In the serial monitor I can see that the ADK will boot and attempt to get the Android device to do something and fails (it tries this continually unless a device successfully enters accessory mode and responds).
Both these devices are supposed to have support for the ADK and I've checked the devices and both have the correct .xml and .jar files for doing so. However, I'm currently running CM10 on both devices and I'm wondering if perhaps the kernel doesn't have the accessory mode enabled or if there's another stumbling block inherent to CM10.
Doing some google research I see that certain updates (4.0.3) have broken ADK support in the past, so perhaps it's just a Jellybean issue? Is there a way of checking kernel options or flashing a kernel known to work? I'd like to narrow down some of the possible issues here.
Hey mate!
I had the same issue, I fixed by using the library version 2 from labs.arduino.cc/ADK. You can download it directly from here: labs.arduino.cc/uploads/ADK/GettingStarted/ArduinoADK-beta-001.zip.
From what I've read the problem is that Android 4.1 uses adk version 2 and has some incompatibilities with the previous version.
Best,
Alex
PD) Sorry for not hotlinking can't do it yet with this account
I've been using that version and still get no response from the Android device. I suppose I'll have to flash stock 4.1 and see if that works, Sadly there's very little proper documentation on this and not a lot of people seem interested in accessory mode devices.

Hi mate,
I hope that you are able to see this message. I have the similar issue. I tried using this version 2 of this library and when i compile the example code "demokil_20", i get the error " 'USB' does not name a type".
Please help me out here.

I got the same USB error. I haven't figured out the problem yet, but I was able to get another example from the version 2 adk library working with jelly bean. I think it was called termtime or something like that. It recognizes the phone the and will pop up saying theres an arduino accessory attached and there is no application to open for that accessory. You can change the example code to "Google" and "Demokit" to auto launch the Demokit.apk app.
I just got this arduino adk two days ago and only have one Android device, a Samsung Captivate with slimbean rom, to test it on.
The first firmware for the Samsung Z3 is now available. Anyone had a play with it? It doesn't flash onto a TM1 dev device. I wonder why?
http://www.tizenexperts.com/2015/10...ware-now-available-to-download-z300hddu0aoj4/
Only theory because only research without device...
1.
TM1 device with reference Firmware from July interact only with THOR aka lthor as Download Tool...
How to identify what I have...
1.1
*#1234# should not show Versions info...
1.2
But su should be in bin folder so have ROOT access and could do funny dump action to check more...
SDB ROOT ON should work...
2.
Z3 or TM1 with Z3 Firmware...
2.1
*#1234# should show you Firmware Version
2.2
SDB ROOT ON maybe not work because NO Binary su in bin folder...
TM1 with Reference Firmware not work with ODIN because THOR is send as "handshake"...
Extract sboot.bin and search for text string:
Code:
ODIN
or
THOR
"Easiest" modification should be on Firmware package...
Code:
csc.img
dzImage
dzImage-recovery
modules.img
nvitem.bin
ramdisk-recovery.img
ramdisk.img
rootfs.img
[B][COLOR="Red"]sboot.bin
spl.img[/COLOR][/B]
SPRDCP.img
SPRDDSP.img
Remove sboot.bin and spl.img from package...
Then in theory device have second chance, if something is wrong, because old Bootloader are present and not overwritten...
For me 600 MB upload is tooooo much... sorry.
Please, if somebody try... then please copy and paste Odin log...
Thanx in advance.
TM1 user before stupid tests could dump eMMC before...(part of it).
Something like this:
Code:
sdb root on
sdb shell
dd if=/dev/mmcblk0 of=/sdcard/FULLdump.bin
Output looks like this... in theory... here taken from Z1 or RD-PQ... forgotten which one... but after 4000 MB stops:
Code:
sh-4.1# dd if=/dev/mmcblk0 of=/sdcard/FULLdump.bin
dd: writing to `/sdcard/FULLdump.bin': Die Datei ist zu gro+ƒ
8388608+0 records in
8388607+1 records out
4294967295 bytes (4,3 GB) copied, 444,287 s, 9,7 MB/s
You could dump less... but if your SD card is big enough...
In Z1 dump I can find text string ODIN after 35 MB... so sboot.bin is inside first 40 MB....
No idea if also in Z3 same location...
Will try to find PIT... all I can remember... TM1/Z3 has 1 partition more...
Best Regards

NO!
Different Hardware.
Different Bootloader, different partitions, filename convention, many huge differences.
If you have RD-PQ... you could update to 2.3.1 Binary with lthor...

No. This is ONLY compatible with the Z3 SM-Z300H.

I have RD-PQ since few days... with 2.2...
I will try to use my Notebooks this year to update to 2.3.1... and see self...
I have no idea... maybe you have chance to got SM-Z300F:
http://www.tizenexperts.com/2015/10/video-russian-samsung-z3-sm-z3000f-gets-reviewed/
I have no idea if RD-PQ will see 2.4 Firmware...
Sorry.
But I am 99,9 % sure SM-Z300H and TM1 Firmware are incompatible with RD-PQ.
If you unpack/extract Firmware package you shoud see why...
Z3 Firmwarepackages contains all Bootloaders accept PIT file...
Why Bootloaders should be ready for RD-PQ aka GT-I9300?
Or Kernel?
Why 1 Kernel supports more then 1 device?
RD-PQ is old...
2 years + older as Z3...
I9300 and/or RD-PQ Hardware is cool enough... :good:
...but why should commercial Developers like Samsung concentrate on old Hardware...
See, I love RD-PQ/I9300:
http://forum.xda-developers.com/showthread.php?t=2482563
I wished support never ends... but this is an dream.
Little example from now.
TM1 devices have Firmware from July... with beta 2.4
On RTL you can see SM-ZTM1 called devices with september Firmware...
And since Z300 + Firmware is avaliable...
We know that minimum 2 compiled Firmware from October exists... and Tizen API is on Z3 2.4.0.1
I have no idea, if TM1 will get Firmwareupdate...
Best Regards
I'm not complaining Just sharing my observations Tizen 2.3.1
If Samsung issued a ready Tizen phone I expected new firmware is more stable and usable.
And I got that Z3 firmware is incompatible.
Samsung Z3 gets second software / firmware update in India – Z300HODD0AOK1

Sorry, joke...
Maybe I will download Full BOL4 ... and try to find something...
Tizen Store Version changed ?
BOL2 is 1.4.1
In theory it would be much easier... to catch the TAR file... look inside...
Then you could see which files changed...
Example from Z1...

delta.kernel
delta.modem
delta.ramdisk

delta.ua
nvitem.bin
[B]sboot.bin[/B]
update.cfg
sboot.bin is for instance ever FULL Binary...
So for Z3 you can be sure... 1500 KB (50 %) from this FOTA (3,6 MB) update is Bootloader.
If someone could provide please the info...
I need only filename of Z3 FOTA Binary..
Something like
12345.bin
You could easily find this info in Logfile... after FOTA update...
Maybe someone could tell me please in private... PM...
I need not the full link... only Filename.
Than in advance.
I can not try self... no Z3...

same 1.4.1 at tizen store.
i dont have the update bin..sorry

Oh.... Why the hell Samsung didn't gift an equivalent android handset as a gift for employees in the fistive season? ?
I am a Asus trio tx201la owner and were completely upset that asus offered no other updates beyond android 4.2 to the tablet part. I noticed that samsung did the exact same thing with the samsung galaxy tab 3 10.1 and so did Dell on the venue. The venue and the galaxy tab 3 have same intel atom z2560 cpu soc and is stuck on android 4.2.
Unlike the Asus Trio the Galaxy tab 3 got a lot more attention and thus a lot more custom rom attention.
The galaxy tab 3 has been updated to 7.1.1 with custom rom by linage OS see:
http://techbeasts.com/install-androi...lineageos-141/
Now How can that help the Trio. The Trio has the same soc and is detectable by the intel platform flash tool released in 2017:
https://01.org/android-ia/downloads/...lash-tool-lite
Stock 4.4.2 android provided by intel: https://01.org/android-ia/downloads/android-4.4.2r1-ia2
Then I found a guide on how to use the tool here: http://www.aryk.tech/2016/04/how-to-...ing-intel.html
So I thought I was off to the races to make the update. The problem was I needed a flash.xml and fake the galaxy tab 7.1.1 update onto my tablet but no where could I find this file and certainly not one meant for my tx201la tablet. So I was stuck once again with no update path.
Then I found Remix OS and thought I had something but nope, again I cant find any info on how to get remix to boot on a android tablet? Ive also looked at running chromium OS on my tablet but that update path also seems to be blocked. So is there an answer or is my x86 android tablet dead?

First, you do not want to flash the Galaxy Tab 3 ROM, since while they do share the same CPU and chipset, the same can probably not be said about the rest of the components, from the screen to speaker(s) to the vibration motor (if it has one), so you may well be left with a tablet that barely functions.

About Remix OS, it depends on whether you have a standard EFI (yes, there are 32-bit EFIs) or BIOS, or rather an Andtoid bootloader like most ARM Android devices.

Why is running Chromium OS not an option for you?
Could it be related to the BIOS/EFI/bootloader?

On the galaxy tab 3 consideration, doesn't android use a generic display driver making this possible? I get how some of the parts could be different but it would seem that generic driver support may fill in the gaps, no? Apparently I could get there with MultiROM and see if it at least will boot. It may not I guess. Am i just wasting my time?
Chrimium OS would be great the problem is how to. I look into getting chromium os onto this tablet but all the info was related to installing on a intel pc with a bios. My tablet has android bootloader and I guess that is the big problem. However it seems that if you have root access it should be possible to change the boot kernel that loads or is that not possible? Gentoo is linux just like android so it should be possible to bypass the boot process somehow. Any how to's to do this? Ive googled to no end and it seems all the pieces are there but not any connection between them to run on a z2560 soc like mine.

In terms of display driver support, while ignoring the rest of the hardware, it depends on how the ROM was compiled, and even if you manage to get a picture, unless the screen gets properly detected, you'll only get a resolution of 800x600.
Plus, the touch sensor on the screen requires a completely different driver, to which, as far as I know, there is no standard.

The Android bootloader is based upon Coreboot, however it is specifically built to only boot system's that adhere to Google's boot procedure standards, so while it is theoretically possible to boot any Linux distro with it, you'll need to find one that was specially compiled for it.
The BIOS and EFI utilize completely a different standard, which means that to get a BIOS/EFI complient system to boot, you'll need to completely replace the bootloader, regardless of root or custom kernels.
And unless someone had already compiled one for your device, you're looking at a feat that is way above most people (even experienced enthusiasts), since this is goes much deeper than the OS.
While in my opinion, the time spent researching this is definitely worth it, unless you find a custom-built BIOS or EFI, or you learn how to build kernels and ROMs (the latter is easier), your tablet is pretty much stuck at where it is for the time being.
That said, I prefer to look at this kind of situation optimistically, without deluding anyone.
The current situation may be rather bleak, and the chances of getting out of it may be slim at the moment, however they exist, and they are slim at the current moment, nothing given about the future.
While we shouldn't get high hopes, we must not extinguish them either.
Thanks for the info. Ill keep looking. I bet some amazing hack will come out in the future to bypass the boot process. Multirom already sorta does this, so the least I can do is test it.

I too am sure of it, however I try to be wary at the same time.
I'd like to point you in the direction of Coreboot and Libreboot for information on some of the possibilities.
I'll check them out..
Update: looks like there sorta replacements for a bios. Maybe the devs will attempt an android bootloader port.

I'm by no means an expert, however I may be able to glean some information from it that may help towards building one for your ASUS tablet.
Unfortunately that is what stopped me from flashing the galaxy tab 3 linageos image on my tx201la tablet, there is no flash.xml included because you need to flash via custom recovery.

I love the tablet, bought two of the 4GB/64GB for $149 each directly from Samsung site.
Well worth the money, I got them for gaming and watching videos, web surfing, really great tablets.

Bought this thinking it was an upgrade from my Galaxy tab a 8.0 but since it's one ui core it's missing many features. Trying to trade it in now but it's past the 15 days. There's no smart view to mirror to any tv easily, theres no network file manager in my files (can't access G drive or any others).
Just make sure you know what you're buying. It's not lite because of being smaller than A7, it's a stripped down OS and the features can't be installed afterwards (have tried many apks). I didn't want a big tablet, wanted a mid size tablet with upgraded CPU.

Just make sure you know what you're buying. It's not lite because of being smaller than A7, it's a stripped down OS and the features can't be installed afterwards (have tried many apks). I didn't want a big tablet, wanted a mid size tablet with upgraded CPU.

I agree with that. If you are sure you know what you're buying, the experience of the A7 Lite isn't bad. One UI Core is the same stripped down OS in the regular A7 (Snapdragon 662) and in the A7 Lite. CPU works very fluid if you tweak some settings (default One UI animations are awfully slow). Battery lasts A LOT (8,5-9 hours SOT). Smart View was removed and changed in all One UI devices with the upgrade to Android 11/One UI 3.0 (regular and Core), and it was replaced with Google Cast native screen mirroring (ergo Chromecast).
Use Solid Explorer or Amaze if you want to access network file places. It works well on my side.
Despite being a Mediatek tablet, you wont't find anything MTK-related in the tablet. Samsung has its software very well masked. And I think that, in Helio P22T, Mediatek vulnerabilities have been fixed with security monthly patches.

I guess that MTK-su has been fixed on Android 11... But I think that I could boot something with DSU Loader, which is available...

Just wanted to chime in here and say that I successfully rooted the tablet using the same method for the Lite as the regular A7 using THIS GUIDE. Obviously it tripped Knox but I needed it rooted for my use case. One note is that when you download the stock firmware with an application like Samsung Firmware Downloader, make sure you choose the correct Model and Region. These can be found in the settings on the tablet.
Is it possible to enable Google Discover for default launcher?
I bought Galaxy Tab A7 Lite LTE SM-T225 3/32GB and it works quite nice. Small and good device. Would be cool to see on it clean Android or LineageOS (fingers crossed). There is not too many ~8 inch tablets today with the latest Android version.

Yes it can
I've been working on porting TWRP for AOSP Android 11 to this device but have run into some roadblocks.
I currently have TWRP running but touch is not working and I can't seem to get Data R/W with the current tools available. It's possible it's an error in my build or maybe a workflow problem.
If anyone out there with more experience is doing the same or wants to help me sort some things out, please let me know.
I purchased the SM-T225 LTE 4/64GB model, a good device, but there was a problem on the latest T225XXU1AUH5 & UI3 firmware, specifically with a modem... after the end of the call, the mobile network disappears, and after rebooting Baseband Unknown Flashing does not help, only resetting the data helps, but before the next call... The device had Root rights, but is now installed stock firmware and blocked the bootloader, but the problem remains... At the same time, if you install the old modem UDA,UE3,UF2 , it works without problems... Has anyone encountered anything like this?
My only disappointment is that knox is included. I came from tab A 8.0 2019 which has no knox

I have a SM-T225 LTE 4 / 64Gb model. 64-bit model, 3 / 32Gb variant is the same in parameters, except for the amount of memory ...
Screenshots from the Phone Info program:
Bought one earlier today for a second screen for browsing while I'm gaming on the laptop. Got way more than I expected for such a cheap price. Debloated and tweaked, I really can't complain.
