Kernel source

I asked a kernel Developer that does the oxygen kernel a few questions he said we need to get the GPL source of our kernel if we want to get anywhere with this.

so someone has to ask Kogan and somehow pry the information from their brains. Not sure if we can ask the EMDoor or the manufacturer but i dont have any way of getting information from them.

once we have a source we have a starting point i guess =P.. anyone any ideas?
[Android Software/Hacking General [Developers Only]] dwl99:
I already emailed Kogan asking for a source to download the firmware but no response as yet. I also emailed Emdoor asking for a copy of the latest 2.3.3 firmware for the EM73 (on which the Kogan is based) but again, no reply as yet. I have more recent EM73 firmware running quite happily on my Kogan but the basic bugs remain.
[Android Software/Hacking General [Developers Only]] flipside101:
The question is as this is a semi generic model could we use kernel source from either the platform maker (telechips) or one ofh the other rebrands?
[Android Software/Hacking General [Developers Only]] dwl99:
There have been sporadic reports of unresponsive bootscreens after flashing EM73 versions of the bootloader (lk.rom) but I assume that it would be safe enough to try other kernels as long as you had a backup of the original (which we do)? For instance, we could try the version of CM7 on the androtab website which would include a new kernel http://androtab.info/telechips/firmwares - scroll down to Emdoor EM73 capacitive GB ROM 8K. Although there are too many things broken on it to make it suitable for daily use, e.g. no wifi, gapps, HDMI out. I wonder if there is a stable CM6 anywhere?
[Android Software/Hacking General [Developers Only]] Wagster:
Hi guys,

Sorry to interupt the dev talk but I can't find a decent general forum for the Kogan so was hoping you guys could help.

I've got an SD card in the Kogan but when I connect the Kogan to my PC I cannot mount the Kogan as mass storage. I don't get any message in my notification tab at the top of the screen and I cannot find any way to turn it on through the Settings menus. Has anyone else experienced this?

Many thanks. And keep up all the good work!:)
[Android Software/Hacking General [Developers Only]] fun_:
no such a report :(

it works :(

EDIT:

in general, flashing lk.rom on telechips tablet (which doesn't have USB boot mode) has a risk to some degree. if there is no reason to flash lk.rom, you should not flash lk.rom.
[Android Software/Hacking General [Developers Only]] dwl99:
I was referring to your post here http://xdaforums.com/showpost.php?p=15173946&postcount=166 but I meant touchscreen, not bootscreen.

I'm confused - http://androtab.info/telechips/firmwares says "current status (2011/6/19)

not work: camera, hardware accelerated video, HDMI, suspend/resume on EM51/EM71, mount from PC on Kyros 7015, USB host on Scroll 7", and many things which you expect to work

work: accelerometer, audio, gapps, internal flash, sd card, touchscreen with calibration app, wlan" so I thought all the items listed were broken? I just realised I misread it & didn't see the word "work"!

So I guess anyone flashing this version of CM7 should be able to restore the stock 2.3 from CWM?
[Android Software/Hacking General [Developers Only]] Parastie:
Emdoor sent me a rather outdated firmware for my resistive screen device. it was 05052011, and was also a 2.3.1. They person who sent it to me, probably a PR person for emdoor) did so over skype and it took several weeks to setup a time. They said it was the most updated they were aware of for my particular device. I'm going to send an email asking for something a litter newer.

The Android Source for these devices is probably held by Telechips. I'm talking from previous experience when dealing with a SmartDevice. Telechips did eventually give the source for the 8902 devices, but have not done so for the 8803.
[Android Software/Hacking General [Developers Only]] fun_:
hard to think bootscreen as touch screen ;)

anyway, no one knows actual reason about death of touchscreen. it happened on stock rom, and not after flashing lk.rom :(

so there is two general notice,

1. flashing lk.rom on any telechips tablet may have a chance to brick it

2. some EM73 capacitive have problem around touchscreen

(or 2. cheap chinese tablet is really cheap)

sorry, I'm not sure what you asked...

you can restore(flash) 2.3 rom (or any rom) with FWDN or fastboot. if you install clockworkmod, you can use it to restore from backup.
[Android Software/Hacking General [Developers Only]] flipside101:
Is it worth while petioning or just emailing telechips to see if we can get hold of the kernel source ?

EDIT: i sent an email
[Android Software/Hacking General [Developers Only]] dwl99:
I'm certainly no dev :-)

Try Settings -> Applications -> Development -> Enable USB debugging
[Android Software/Hacking General [Developers Only]] dwl99:
Okay, I've taken a deep breath and just flashed CM7 on the Kogan and can confirm that it hasn't killed my tablet :-)

Will have a play around with it & report back. The touchscreen works a lot better when charging but there's no sign of any Google apps so I'll need to have a hunt around for them.

EDIT - AAAArgh! I just rebooted & the touchscreen is unresponsive. Will try a CWM restore.
[Android Software/Hacking General [Developers Only]] flipside101:
Was just about to do the same ... I hope the restore works
[Android Software/Hacking General [Developers Only]] dwl99:
Phew - CWM restore worked fine :-)

The first time I flashed CM7 the tablet was charging & the initial calibration screen was a bit funny. I was feeling brave/stupid so I re-flashed under battery power and this time everything went well and touchscreen still working well after several reboots. Now to flash some gapps and get some restoring done!
[Android Software/Hacking General [Developers Only]] vladytepes:
I have problems with the touchscreen too but I can not restore the backup because... well, I erased it (so embarrasing). Can anybody send me one? Now I have a beautiful brick
[Android Software/Hacking General [Developers Only]] dwl99:
If you go back to post # 1 you will see a CWM restore file!
[Android Software/Hacking General [Developers Only]] wlee2:
does this meen that version of Cynogen works? and no random screen wakes?
[Android Software/Hacking General [Developers Only]] fun_:
calibration data is applied after reboot. if you did calibration wrongly, TS might not work after reboot. no need to do calibration on EM73 so TS worked fine just after calibration and before reboot.

I'm confusing about many "TS doesn't work on my CM7" reports. refer http://xdaforums.com/showthread.php?p=15412707#post15412707
[Android Software/Hacking General [Developers Only]] dwl99:
Thanks, that makes sense. It's an awesome ROM & thank you very much for all your work.

The only problem of any significance I've found on the Kogan is a lack of app2sd storage - CM7 has only 15MB app2sd so I have run out of space for installing apps quite quickly. Is there any way to alter this or does Darktremor a2sd work with this ROM? I'll also ask this question on the TCC8803 CM7 forum you mentioned as I hadn't previously found this!
[Android Software/Hacking General [Developers Only]] flipside101:
You may want to try s2e app (another a2sd script that was designed purely for cm7) there's also the option under the cyanagon mod settings to force all installs to sd
[Android Software/Hacking General [Developers Only]] flipside101:
One concern I have about apps2sd is that the way the these tabs use the internal storage as the sdcard and mount external storage as folders so getting the necessary extra partition setup.may be tricky. In which the the cm7 modded googlemail app2sd route may be the best bet.

Admitidly I'm.basing these thoughts on.the stock rom fun_'s cm7 may do it differently.

Gonna install today and have a play
[Android Software/Hacking General [Developers Only]] dwl99:
Thanks for the info. Quicksysteminfo now shows only 7MB total space available for app2sd :-(

I had a look at s2e - am I correct in thinking that you use it to import the darktremor a2sd settings to CM7 and then use an EXT3 partition on the SD card? Or do I just install the s2e app then create an EXT3 partition & it all happens without installing darktremor?

PS I've uploaded a CM7+gapps CWM restore file in the first post to allow for a lazy install!
[Android Software/Hacking General [Developers Only]] geoRG77:
There aren't another rebrands on the market yet, but of course - Telechips BSP != Emdoor BSP.

We went through this with TCC8902 already, maybe you will be able to get (incomplete) kernel source from Telechips, but it is not enough to prepare working kernel unless you will have a kernel hacker/s who will develop/customize device drivers to match our hardware (which will be very difficult to do w/o any documentation).

Emdoor is in hold of (customized) TCC8803 BSP too, but there is no way how to get BSP from a Chinese company.

You can start legal battle with Kogan, I am pretty sure GPL license is valid in Australia.
[Android Software/Hacking General [Developers Only]] flipside101:
Ive installed cm7 gapps and partitioned my sd card using cwm4 .. ive just installed simple2ext and it recognised teh ext partition. Now booting to see if anything gets moved

EDIT: rebooted and its working like a charm ... wish we could use the internal nand though especially for dalvik and app data as this would be much faster
[Android Software/Hacking General [Developers Only]] dwl99:
I just did this too and now have >400MB A2SD showing as free with Quicksysteminfo! This ROM puts the Kogan into a whole different league. It boots much quicker, the screen is more responsive and the accelerometer much less jittery. I've only been running it for half a day but I'm already very impressed. The lack of HDMI out and hardware acceleration is a small price to pay. It serves only to underline what carp firmware they had on it originally.

Some CM7 ROMs can be a bit heavy on the battery so I'll be watching this closely.

What size did you make your EXT3 partition? Did you bother with a swap partition?

Moboplayer doesn't work with my H264 videos but Rockplayer Lite does if software acceleration is selected.

Does Wifi work? because i thought i read on his website that it does not work?..

i might consider flashing Cyanogen if wifi works ^_^.. cant stand my current rom on it its bugging me sometimes it works sometimes it doesnt
[Android Software/Hacking General [Developers Only]] dwl99:
Wifi works fine. The info on the androtab site is easy to misread - I missed the word "work" and assumed that all the features listed were broken.

"not work: camera, hardware accelerated video, HDMI

work: accelerometer, audio, gapps, internal flash, sd card, touchscreen with calibration app, wlan"

The camera is rubbish anyway but HDMI & hardware acceleration will be good when they arrive. Give it a go, you can always go back to the stock ROM from a CWM backup. But you won't want to!

You can also use an app called s2e with CM7 which allows for installation of any app to the SDcard.
[Android Software/Hacking General [Developers Only]] wlee2:
Would be nice to use the camera as a skype camera but in all seriousness i am still going to try this =P. i cant stand the current rom .. hope it does not brick me device hehe =P is there a Instruction in the front page yet hmm..

better go check that now.

[Android Software/Hacking General [Developers Only]] vladytepes:
I have a TCC8803 based tablet (coby kyros mid7022) I have tried to flash it with FWDN but it didn´t work. Now I can not go back to recovery mode, I am just stuck on FWDN or Fastboot mode. When I press the reset button at the back, I just get a logo with some chinese letters and android2.3 at the botton. It is constantly rebooting without doing anything else. My pc windoes 7 32bits recognizes the tablet, in both modes. In Fastboot mode I have an ADB interface in windows Device mode. I have also download android sdk but I am not sure of have all the files I need. And finally, I have installed the Android Commander as was suggested in this forum. I set up the path and when I start the program, it can not find the device. So I can not use it either.

As I see it I have two ways to solve this:

1) Using FWDN with some files that work (the problem usually comes with the NAND Data.fai file)

2) Find a way to have the recovery mode back and use clockwork (I have done this before this mess)

I really appreciate any help because I am almost desperate. I just have a brand new brick and three days of my vacations wasted on it

Thank you very much

I am very tempted to try the CM7 rom but one of the main things that I like is playing films to my TV via HDMI when I am not at home.

So my question is; if do flash CM7, is it possible that there will be a fix for the HDMI in future or am I better of just leaving the tweaked stock on for now?

OK really showing my noobieness now.

Have successfully installed clockworkmod and made a nandroid backup. Now I am trying to root.

Downloaded superoneclick v1.95 and the Drivers 32 from link below. I assume the drivers are for superoneclick ?? so I unzipped and placed them in my \Downloads\SuperOneClickv1.9.5-ShortFuse\Drivers\x86 folder. I am running Windows 7 premium 32bit.

Set the tab to debug mode, connect USB with tab ON. Bug icon appears in status bar. I then execute superoneclick and press Root. superoneclick says checking drivers,OK. then a couple of adb.exe windows pop up, while the superoneclick window says waiting for device. If i close the adb.exe window it says "automatic version checkl failed is your version OS 2 or higher?" I click YES and I get this.

SuperOneClick v1.9.5.0

Checking drivers...

Killing ADB Server...

OK

Starting ADB Server...

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

OK

Waiting for device...

OK

Getting OS Version...

Pushing psneuter...

error: device not found

This is the same message I will get if I try and run superoneclick without connecting the USB to my tablet. So I assume the windows side cannot see the tablet so I have not installed things right.

What am I doing wrong?
[Android Software/Hacking General [Developers Only]] dwl99:
You can! Copy all files from your SDcard to your PC. Use CWM to create a 512MB EXT partition (Advanced -> Partition SD card, NB this will wipe your SD card) then power off. Put the SD card back in your PC & copy all your files & folders back onto it & reinsert into tablet. Start it up & install s2e from the Market, tick the Applications , Data & Dalvik Cache boxes & reboot. Install Quicksysteminfo from the Market to see how much A2SD storage you have. I have an insane number of apps on my tablet now!
[Android Software/Hacking General [Developers Only]] flipside101:
@dwl99 what I think wlee2 means is the same question I've been asking across the em73 threads. That being using the internal /nand partition (in the stock Tom this was mounted as the sdcard) for apps. I have found an apps2nand script in the scrolltablet forum but I don't think its viable in it current form.

One other thought (and this is clouded by my very limited knowledge of how androids internals work) I had was that to me it looks like the 4gb internal nand contains the system as well so shouldn't it be possible to mod the mtd to expand the /data partition out to use more of the space...
