I see, I don't know why but it seems calibration app doesn't work on your tablet...

I want to "working" report on another tablet ;)

calibration app from stock rom must work. (I included it from some rom in my old CM7, but I didn't work on some tablet)

please delete my calibration app(/system/app/TSCalibration.apk) and add app from your stock rom.

--

btw in stock rom/stock calib app, values are stored in sysfs(kernel) (/sys/somewhere)

(no need to explain/investigate about it. I know well)
[Android Software/Hacking General [Developers Only]] flatpackpete:
Well the issue is two fold, first I'm still new at all this and while I've got the hang of making my own update.img I'm still not too good with cramfs so packing/unpacking of the system.img is beyond me at the moment.

Also the other problem is the calibration app I uploaded is usually launched from the settings program, it don't know how to make it appear in the app folder with it's own icon etc.
[Android Software/Hacking General [Developers Only]] fun_:
calib app in my stock rom(what I used previously) also in settings but it starts automatically on 1st boot.

did you read archosfans wiki to make custom update.img?
[Android Software/Hacking General [Developers Only]] Kalimerou:
I also tried to do an "inverted calibration" but nothing changes ;)

I'll check the calibration app provided by flatpackpete as soon as I can. Currently I'm shifting to another appartment so I'm a bit busy ^_^

But I made a tentative with the TSCalibration.apk from the N3net firmware, it doesn't work neither... the app crashes at boot.
[Android Software/Hacking General [Developers Only]] flatpackpete:
No, I sort of figured out how to unpack, change boot and system and re-pack. I think I've got a bit of reading to do ;)
[Android Software/Hacking General [Developers Only]] fun_:
hmm. sorry & thanks for your cooperation.

btw no calib app in your original stock rom?

just FYI I can use calib app in stock rom & in N3net rom on my tablet (mivvy A2/ONN N2) with CM7. of course my calib app in CM7 also works fine.

probably I need to make "working" "not working" list ;)
[Android Software/Hacking General [Developers Only]] fun_:
sounds nice! enjoy! :)
[Android Software/Hacking General [Developers Only]] flatpackpete:
For the record, someone needs to have a more friendly way of packing and repacking cramfs files in windows, that was a chore.

Right, just as I feared it didn't start. I tried to get it going but nothing seems to be working. I am officially stuck...:(
[Android Software/Hacking General [Developers Only]] Jostey:
What is the utility to add this to build.prop?

Hi,

Someone knows how can I change to host mode from command line. I don't want to goes to settings->usb mode select ->HOST MODE.

I've saw in logcat when I change from settings:

MAX_USB_MODE=1

mode_key=host_mode

default_mode=0

Many thanks!

New Tuxbox FlashTools is not friendly?

I'm not sure what happen, but you can restore your tablet with official firmware, right?

any text editor can do it. but it will not change anything.
[Android Software/Hacking General [Developers Only]] agamemnonom:
what about archos 70b ereader?
[Android Software/Hacking General [Developers Only]] flatpackpete:
Never heard of it (I'm still a noob at this). Could I have a link?

I knew it was a long shot anyway, but I'm sure there will be other calibrators somewhere that will work.

At the moment there's nothing I can do, I accidentally flashed the wrong firmware and I am just looking at a white screen.

It's working underneath, but as I can't turn USB debugging off I can't flash with RK2818 Batch Upgrade.

The good news is I got my tablet from a high street store only a few months ago, so my plan is to go in and say "The screens broke!" and get a new one under guarantee :rolleyes:

EDIT: It's alive!!!!!!! tried adb reboot-bootloader while BatchUpgrade was running and it recognized it!

I don't think I've ever been so happy to be back to square one :)
[Android Software/Hacking General [Developers Only]] arctablet:
Should work as it Rockchip 2818 based.

You'll need to build on own image with boot.img and system.img

i just thougt if it could possible to use something like "app2nand"?? like using nand instead of using sd? apps2sd is not working , so i want to try to use the 750mb-nand for my apps. possible? if so, how?

thx

psypreacher
[Android Software/Hacking General [Developers Only]] rcmc_ronny:
@psypreacher could you send me the link, also ?

I am working on a flashable image for the oneTAB and trying to make it working round, I am not a dev, but more a linux geek, will see what i can do :)

I have also flashed this image, but my wlan does not work as expected, it hangs on "obtaining ip address", with the froyo image flying around it works flawlessly ..hmm

Another issue is the rotation, the screen is always 90 degress forward. Anybody a hint, where to look here ?

Actually, I am using the froyo image and try to make the cm image better ..

Ronny
[Android Software/Hacking General [Developers Only]] flatpackpete:
The upside down app issue could be the accelerometer is not configured right.

Have a look at this earlier post by _fun that explains how to fix that.
[Android Software/Hacking General [Developers Only]] tenshi_xp:
I try this in AOC Breeze MW0811 and not work, tablet never load....

If you need a tester for this tablet i will help you...
[Android Software/Hacking General [Developers Only]] fun_:
thanks. can you tell me detail what you did?
[Android Software/Hacking General [Developers Only]] psypreacher:
the accelerometer works right, i´ve added local.prop. just some apps like adfree start upside down, other running fine.
[Android Software/Hacking General [Developers Only]] tenshi_xp:
First unpack the original breeze OS and replace system and boot .img files, repack an generate a mod.img. Then load the OS with RKAndroidBatchUpgrade at end ok, the tablet restart and load the update system, restart but never can load the OS. Stops about the 20% and i wait for 1.5 hour and nothing.

Reload the original OS and work fine.

[Android Software/Hacking General [Developers Only]] rcmc_ronny:
Hello,

ok, actual status on my 4G OneTAB with this image is:

* Youtube HQ Videos: Audio: yes, but no video (like on CM7 for my HTC Magic)

* Location based on WLAN does not work (don't find any clue in logcat or so)

* Screen goes on after a while and stays on, does anyone sees this to, how is this on other

tablets?

Other things seem to work finde,rotation is find now, wlan works to (permissions must be corrected for /etc/dbus.conf and for /etc/dhcpc folder in /etc)

Ronny
[Android Software/Hacking General [Developers Only]] fun_:
wlan should work without any fix. did you try before modifying boot.img/system.img?

thats very easy but is there any manual for windows user to get cm7?
[Android Software/Hacking General [Developers Only]] fun_:
hi everyone,

if you make update.img for specific tablet and start thread on any open forum, please tell me URI. I'll add links in OP.
[Android Software/Hacking General [Developers Only]] flatpackpete:
What...:eek: dude I swear that wasn't there when I looked. Thanks :)

If your referring to the resistive touchscreen one then there is an issue in calibrating the screen (I refer you to any of my previous comments).

If you have the capacitive one then you may be in luck, although you need to delere the TSCalibrate as mentioned in the first post.
[Android Software/Hacking General [Developers Only]] tenshi_xp:
Well i read the linked topic and try again, make a new update file and it work fine.

The last time never load the calibration screen, but this time works fine.

Audio ok

Video fail in some mkv files

Rotation should be modded with local.prop

Wlan ok

Keyboard lags sometimes

Browser lags sometimes

Very good project, in a few months i will try to do a custom os for this tablet. Well keep working in this project and thanks for helping us to enjoy a better software for RK2818 tablets
[Android Software/Hacking General [Developers Only]] kc85/3:
THAT'S AWESOME! I flashed my 4G OneTab with the .img psypreacher built and replaced the local.prop. For me only few issues (some apps upside down, few fcs, feels a bit slow over all). Absolute fantastic work. Thank you very much.

Only one thing is annoying: The Onetab (screen) always comes back from standby automatically (after 10-15 minutes) and then the screen stays on. Display timeout is set to one minute but is ignored.

That eats the battery very fast ...

[Android Software/Hacking General [Developers Only]] fun_:
hmm... did you erase /data on 1st CM7 install?
[Android Software/Hacking General [Developers Only]] rcmc_ronny:
hmm it could be the reason, normally, the install says, that it formats data .. but perhaps not correct. Flashed the new image from 04.08.2011 and have had not this issues, weired :)

[Android Software/Hacking General [Developers Only]] ThauExodus:
Would it be possible to mount /system as ext3 instead of cramfs, so we have full r/w access and can easily make changes without reflashing the rom.
[Android Software/Hacking General [Developers Only]] flatpackpete:
No :)

You need to unpack a standard update.img with the updated files, put in the root of your SD card and your tablet will automatically update.

Have a look here for details of what to do.
[Android Software/Hacking General [Developers Only]] flatpackpete:
Don't think so. It seems the Rockchip expects the CRAMFS files, hence the reason we have to do all the extra work if you compare the standard zip files most andriod phones can handle.

You have to remember the RK2818 is more than a processor, it's a system on a chip (SOC) package, so it sets the rules and we have to work within them....most of the time ;)
[Android Software/Hacking General [Developers Only]] fun_:
technically possible.

there is custom rom for rk2808/rk2818 tablets which has rw /system.

they mount another partition as /system on top of cramfs /system, or they use unionfs(aufs.ko).

whole system on external sd card is also possible ;)

Purchased Arnova 8 today for £100 from ASDA. Already have iPad but like android.

Not too impressed even with it unrooted.

Managed to find this site - AGAIN after previously using it for WinMo.

Worked through the creation of update.img.

Flashed.... fingers crossed - this is being written during booting...

Looking good - just calibrated....

Rebooting "phone"...

Nice startup chaps...

ANDROID in text near the bottom tells me its all going well...

Droid on a skateboard - nice... You guys ROCK!

I am hoping this update improves performance over 2.1 (ouch)

Back into the OS... YES!!!!!!!

Testing will report back.
[Android Software/Hacking General [Developers Only]] ghorricks:
Sound Working through speakers and headphones.

Screen working ok.

More responsive than Android 2.1.

All hardware buttons working.

Turned brightness all the way up (Yep works).

Multitasking okay.

Notifications good.

Nice customisations.

....Wi-Fi - No problems (Just WEP tested for now).

Now for the browser...

Youtube.com... selected video....

Opens up an app... Just a blank screen but sound is okay.... Video issues?

I have a DivX video that previously worked... lets see...

"Sorry this video cannot be played" - Likely codecs I would think.

Nice fileManager incidently.

BBC iPlayer did install - needed flash to download, but that needed an account.
[Android Software/Hacking General [Developers Only]] John_Snow:
ghorricks, could you upload the update.img?
[Android Software/Hacking General [Developers Only]] ghorricks:
John_Snow - I am not sure about the legalities of doing this. Admins please advise.

It was actually VERY straight forward to make.

You need an existing update.img & the two files provided (boot.img & system.img).

In a nutshell, you extract the contents of an update.img for your device.

Then replace the extracted boot.img and system.img with the ones provided.

Then pack the extracted content using the same DOS tool.

The DOS tool is called "AFPTool.exe" - use google.

There is a link to the instruction back on page 1 of this thread, only it looks intimidating for a beginer.

(http://wiki.archosfans.com/index.php...e_a_custom_rom)

2 bits are important:

>APFTool.exe -unpack update.img unpacked

then copy in Cyanogen's 2 files over the original ones that are in a sub folder....

>AFPTool.exe -pack unpacked update.img

I understand the frustration, but a little reading and basic DOS skills are all that is required.

how to install boot.img and update.img on the archos 7htv2?

i have try ti flash it with the rk tool but no chance.

Please help me
[Android Software/Hacking General [Developers Only]] ghorricks:
How would I return to the original image?

I have the update.img file - please tell me this is enough.

Also, clockwork doesnt work as there are no volume buttons on the Arnova 8.

Its crucial that I can update to other ROMs easily and I dont see an easy way to do that.

Does the message:

e:cant open /cache/recovery/command

mean anything to you guys in the know?

Although ROM Manager says clockwork is installed, when I reboot it goes to Android Recovery and not clockwork.

Not having such a great time right now - think I will take my iPad onboard the flights I will be on next week until I can figure it all out.

[Android Software/Hacking General [Developers Only]] flatpackpete:
The easiest way is by using RKAndroidBatchUpgrade. Have a look here for download links and quick guide on how to use it
[Android Software/Hacking General [Developers Only]] fun_:
kernel.img, boot.img and most part of system.img are free. some binary blobs in system.img (taken from stock rom), and other parts of update.img (e.g. RK28xxLoader.bin) are unclear.

but I think(I'm not lawyer, it's just my understanding) it's ok to redistribute it because we need entire update.img to use their GPL components ;)

--

why I don't make/distribute update.img myself is clear, it cosumes time and a lot of disk space ;)

there is more than 30 kind of RK2818 tablets. if I start to make update.img for some tablets, other tablets user want it for their tablets...

and I have another project, I already make 30+ sets of CM7 images for them. it consumes 4GB disk space per each release and only 2 release can be stored on my server :(

and as you know/said, replacing boot/system.img is very easy. I'll add simple how to on my site/OP.

windows is requied to do it, but it also required to flash it.

(I know "put update.img on SD card" way, but it doesn't work when android part doesn't work)

[Android Software/Hacking General [Developers Only]] Kalimerou:
I can confirm that the issue is related to the calibration app. Once my /system was mounted rw, I replaced the /system/app/TSCalibration with my device stock firmware apk : http://www.megaupload.com/?d=ZBN3PIH5 (Onda VX580w Android 2.2 firmware).

Then rebooted my device. At start the system asked me to run the calibration again, and then... everything's fine ;)

I finally can use this awesome firmware :D

Just one more question : is there any key combination / shortcut to lock the screen ?
[Android Software/Hacking General [Developers Only]] fun_:
power key doesn't work? or you want screen lock but screen on?
[Android Software/Hacking General [Developers Only]] nikos-p:
Worked like a charm! Thank you
[Android Software/Hacking General [Developers Only]] Kalimerou:
I believe that the power key works as it is supposed to ;)

When on standby, a short press on the power key turns on the device and shows the unlock screen.

When using the device, a long press on the power key shows the shutdown ("Phone options") menu but there's no lock / screen off option.

A short press does nothing, except doing the "back" action in menus.

I would like to be able to lock screen on demand, so that to put the device in my pocket after I used it. It is hard to do ?

BTW : thanks for your great work ;)
