[Q] Root/Clockwork mod on TCC8803 tablets - Android Q&A, Help & Troubleshooting

Hello!
Idiot’s guide
Most of this is based on discussions with _fun, and borrows heavily from his website http://androtab.info and personal experience. I accept no blame for following my guide, but it should work okay. In other words; DO THIS AT YOUR OWN RISK!
DO NOT USE FWTOOL! YOU WILL BRICK YOUR TOUCH SCREEN!
What you need
Files: http://androtab.info/telechips/firmwares look at the bottom of the page for TCC8803 files.
You must determine if your device has a 4K formatted NAND or an 8K formatted NAND. I’m still fuzzy on how to do this, so it’s probably best to ask. I’ll update this as soon as I get more info! My device is 4K and has a resistive screen. The Kogan Agora is an 8K device.
MicroSD card. You cannot flash the device without a microSD, unless you plan on using FDWN and that’s a tutorial for another day.
Stock Recovery
There are 4 boot options for the EM73, standard boot, recovery boot, FDWN boot, and fastboot. The two important ones (for now) are standard and recovery. Standard boot means you don’t press any buttons while powering up and it just boots up normally.
To get into recovery:
Turn your device off.
Hold the BACK button (big one on the front of the device)
Hold power until the device turns on, then release power button. CONTINUE HOLDING BACK BUTTON
Device will boot into stock recovery, and you can release the BACK button
In stock recovery, you can now flash Clockwork mod, or another stock update should you find one that works. As far as I know, there aren’t any but I’ll update this post if it becomes available.
To navigate stock recovery:
HOME and MENU (the 2 side buttons) move up and down the list
BACK button selects
How to dump stock recovery
download dump-recovery.zip http://androtab.info/files/tcc8902/dump-recovery/dump-recovery-signed.zip
Rename the dump-recover-signed.zip to update.zip
Place the update.zip in the root of your microSD card
Boot into recovery
Choose to install the update from the list
Files will be copied as /sdcard/dumped_recovery.img and /proc/mtd will be copied as /sdcard/dumped_proc_mtd.txt.
How to install ClockworkMod Recovery 4
make backup(dump) stock recovery
download recovery.zip (follow the link at the top of this tutorial to find your files)
Rename recovery.zip to update.zip
Place update.zip on the root of your microSD card
Install update from recovery
Navigation
Navigation is different in ClockWorkMod Recovery then in stock recovery!
BACK button goes back
MENU button moves down the list
HOME button selects
How to get SU on stock ROM
(Info from this thread: http://forum.xda-developers.com/showthread.php?t=682828 There are other methods, but this is how I did it.)
Install ClockworkMod Recovery
Download this file: http://dl.dropbox.com/u/6408470/su-releases/su-2.3.6.1-ef-signed.zip
Place on the root of your microSD card
Boot into recovery
Choose “Install zip from sdcard”
Choose “choose zip from sd card”
Select su-2.3.6.1-ef-signed.zip
Choose Yes
Reboot!
You should now have SU, be sure to download BusyBox from Market or nothing will really work.
How to install CyanogenMod 7
install ClockworkMod Recovery 4
reboot recovery
make backup
wipe data/factory reset *1
install cyanogen.zip (follow the link at the top of this tutorial to find your files)
reboot
touchscreen calibration *1 *2
reboot again to reflect calibration data
*1 only if you are upgrading from non-CM7 ROM (CM7 1st install)
*2 only if you are using resistive touchscreen or misaligned capacitive touchscreen

hi,
I checked Gpad702 firmware
http://www.szltp.com/download/download38.html
it's same structure as TCC8902 firmware
I can unpack boot.img/system.img/recovery.img in m801_mtd.img.
kernel ver. is
Code:
Linux version 2.6.35.7-tcc (@build-161) (gcc version 4.4.3 (GCC) ) #183 Wed May 4 17:19:20 HKT 2011
and build id is
Code:
MID73_SIS_HI2M 20110504
it's 2.3.1 ROM and I guess it's same as yours. probably making clockworkmod recovery is not difficult

I have a feeling this is also the same version as the Kogan Agora Tablet which is based off the Telechip TCC8803 or probably the same thing just rebranded (also the Haipad M708)
i been looking at trying to get root access as well but still fail.

I compared Gpad701 2.3.1 ROM and Gpad702 ROM. very similar (of course not compatible, but similar layout). I think I can make clockworkmod recovery and cyanogenmod by changing some lines from cmr/cm for tcc8902.
we can change any files in telechips firmware image. (we are superior than root)
adding su and superuser.apk should be easy. I never use rooting app for telechips tablets

I don't have tcc8803 tablet yet. I can't test at all. it may break your tablet. don't use if you can't accept your tablet may be bricked.
(I think if you can use FWDN you can unbrick easily, but I warned!)
here is test clockworkmod and cyanogenmod files
http://androtab.info/files/tcc8803/cm7/
even if it works(at least boot), do not expect many things. it's just a test image!
EDIT:
I found other possible firmware (I didn't get yet)
http://www.megaupload.com/?d=AD7U83D5
I don't know how many variants are exists. my test image uses files from Gpad702. it may not compatible with your tablet. please use them with care!
EDIT2:
oh, nice, 1st one (em73_SISGC2M_V1_20110516.rar) is 2.3.3 ROM
kernel: Linux version 2.6.35.7-tcc ([email protected]) (gcc version 4.4.3 (GCC) ) #97 Mon May 16 11:53:45 HKT 2011
build: EM73_SIS_GC2M_V1 20110516
oops, 2nd one is same as 1st one 2nd link is removed, sorry.
if you want to flash these files (lk.rom and m801_mtd.img), please see this how to
http://forum.xda-developers.com/showpost.php?p=14237828&postcount=2
it is complete procedure
I'll make test image based on 2.3.3 ROM when I have a time.
EDIT3: http://u.115.com/file/bhd55s6m here is another TCC8803 2.3.3 rom for another hardware(1024x600 screen)

Do we need to get root access first to flash the recovery image?
anyone dare try this with their Kogan Agora tablet lol =P

I added tcc8803-recovery.zip. it should be able to install from stock recovery, and replace recovery with clockworkmod. (hopefully)
anyway, you can use fastboot/FWDN to flash recovery without root.
I'm not sure my files are compatible with your tablet. if your tablet is 2.2.x, you may need to flash lk.rom from 2.3 ROM... see GB ROM entry inFAQ on my tcc8902 thread.

i can get adb shell and root on kogan agora using the telechip8803 root recovery
and installed gtalk from 2.3.4
been running fine for a few days, but today it just lost any internet connection
still get ip, still can ping to outside address but no app working, market, browser talk etc
seen a lot of [0]: tcc_setup_interrupt timed_out!! in kernel message
since im not that savvy in figuring out whats the problem, i just did a factory reset and internet connection is back
i'll try cyanogen next when i have time
if anyone need the kernel message log (rooted and after factory reset), let me know

if you can, please try to install recovery.zip from *stock recovery*. it should work, and if it works, it's easy way to install clockworkmod.
cyanogenmod is just for someone who really like cm. not for daily use, e.g. hw codecs don't work

I'm keen to know what you thought of your Kogan tablet - I have one on the way but was a bit dismayed to see the cr*p reviews so far
Looking forward to getting a custom ROM on it!!

Have any of you had any issues with the browser closing when loading google.com only? Also I've had an issue with trying to get a location through wifi with this tablet. I've tried enabling wireless networks and so and still nothing. I think it might be a faulty firmware.

1. get this file :Telepad7C_M708_Telechip8803_Root_Recovery
search for it, i can't post any url yet (need at least 8 post)
2. install the motorola driver
3. there's a how to in the file, but i didn't follow it
instead i just do adb remount, shell and copy the new su and then install superuser from market. done.

the hardware it self is what you get for the price
it's decent enough to use for browsing, reading and media player, even gaming if you like
the battery is bad, standby of ~8h and ~3-4h for continuous usage
the screen is dark and have limited view angle, but bear in mind it's not samsung galaxy's amoled :lol:
it's good for daily use and if you dont expect much for the money you spend
it's bad because kogan tells a lot of crap! if you follow the story from their first ad you will know what i mean

mm was not quite the step by step i wanted more so interested where to download those files quick get your 8 post =P
i agree mostly with what you said Re Kogan tablet battery life is bad it wont survive a full day at work with constant use.
i dont mine the screen all so much it runs angry birds quite well i personally see the view angle thing as a Plus since most people put up privacy screens to stop people from looking in on what we are doing the kogan one does it straight out of the box lOL..
i got the first batch from kogan was a lOng wait but i am glad it was upgraded a bit after the Wait i still think if you bought 2 or 3 of them in one shipping and 3 friends needing it at the cheapest live price at $139 its worth it for a sub 200 tablet
for your 120 bucks more you can try to find a samsung galaxy tab in aus but its pretty hard find now i managed to get hold of one ..
