Also teamhacksung have some repos IP for the cat nova star gate (if I'm not mistaken). I'm attempting to use these to compile something for a m801 device I have that has zero support from the vendor.

Here's my thread link, this should help you.

This is for Coby Kyros 7022 ONLY!!! (change app data space to 1GB) More apps!

I am stuck in this procedure right now. In the mentioned article they talk about a img file, which is needed to expand appspace on the coby 7022, it is called tc8803mtd.img, but whereever I search I cannot find this img file. All I find is a zip file to flash via cwm, Does anybody has a clue where to get this file?

Anyone got an inverted touchscreen after updating to cyanogen or reverting into a stock rom? Example you touch on the left side, but it assumes you touch on the right side and vice-versa?
Any tips?
Thank you

Sorry guys, I know I'm kinda out-of-date on this one, but I recently got one of these tabs, and this is the only place where I found something serious on Telechips m801. The problem is I cannot find it in the list of supported devices, though it's really similar. Could anyone reach out a hand to me in this one? Do you think it will run ok? Could you recommend me any other options? Check it put please.


Thanks in advance ;)


EDIT: I thought it appeared in the images but it doesn't: Kernel 2.6.35.7

Heinzelrumpel, I found your post while searching for the tc8803mtd.img file also. This must be referring to the original CM7 unofficial port to the 7022 that is found on the page androtab.info/cyanogenmod/telechips/ and for the 7022 that page reports the TCC8803 FWDN image is available at files.androtab.info/telechips/cm7/20111029/KYROS7022-8K/KYROS7022-8K-FWDN-image.zip in case you have yet to come across this file. I'm sorry that the urls need to be copied and pasted but because I'm more a lurker than a poster I have not yet reached the requisite 10 posts to be afforded the ability to post them.

it worked on my mid7125 with no issues. made a back up of the original by installing the dump/update.zip thru the settings, about device, system update. then stored that and moved the recovery/update.zip did the same and bam, was in clockwork recovery on next boot by pressing and holding the power and home button. then I made another backup from the recovery. I kept the stock gingerbread 2.3 cause it works fine but at least now I have options. Thanks for all the great info on this thread!

When you say "it" worked on your mid7125, which device did you choose when you downloaded CyanogenMod? I've tried a couple of versions/devices and when I go to install it, it errors out on my mid7125,

Saved the day

I searched several other forums on how to fix my kids soft bricked coby 7012 and finally found your instructions that got my CWM and CyanogenMod installed and the kids tablet working again. I hit the Thanks button but I also wanted to tell you directly. It was stuck in fastboot & fwdn mode from me trying to install CWM in the first place. I can give details if someone needs help as well.

Edit: My screen is dropped below the base and it leaves an open screen on the top when in portrait mode. In landscape mode the screen is too far to the right and you can't see everything. Could someone help me on aligning the screen and to keep apps downloaded from google play from flipping completely upside down?

this is a work-in-progress development project for porting CyanogenMod 7 (gingerbread/2.3.7) and ClockworkMod Recovery 5 to Telechips TCC8902 and TCC8803 tablets.

this is not perfect at all. and I'm very busy. progress will be very very slow. I may not be able to answer your question/request. if you have some idea for improvement, please do it freely.

there is no support from any makers/vendors. you must agree all risks by installing non-supported files, it may brick your tablet, and you may lose official support/warranty.

Is anyone working on fixing the known problems? The hardware video problem would be a #1 request.

Hi people,
our good-old-TCC-tablets are so outdated that it's hard to find any use for them, especially most of them having resistive touchscreen.
So everything I write below is to be treated as an exercise. If experienced developers still read this thread, please correct me below:
  1. pre-4 Android versions aren't as flexible as ICS+ so we generally can't have one /system image for the whole family. (Kernel is still a very device-specific thing, in most cases we need kernels per device)
  2. As a result we have a whole pack of images, each tied to one model. First thing comes to my mind: can anyone make further classification? I mean: classifying by Wifi chip may not be enough. As a whole supporting a Wifi chip by a separate ROM may be quite an overkill. I've seen a Wifi support made as a "patch" zip file installable with CWM after installing a ROM.
  3. A not-yet-supported device support may be based on existing ROMs. But what would be the most crucial criteria of choosing a ROM to start with? My guess is: touchscreen driver. Right? TS controller may even be damaged if used with improper soft.
(*** end of general ideas ***)

    * How to make backup of stock recovery
    1. download dump-recovery-signed.zip and put it as update.zip on root of SD card (e.g. /sdcard/update.zip) *1 *2
    2. install update.zip from stock recovery *3

    stock recovery will be dumped as dumped_recovery.img and /proc/mtd will be copied as dumped_proc_mtd.txt on root of SD card. keep them in safe place.

    * How to install ClockworkMod Recovery 5
    1. make backup of stock recovery
    2. download recovery.zip and put it as update.zip on root of SD card (e.g. /sdcard/update.zip) *1 *2
    3. install update.zip from stock recovery *3

    clockworkmod will be booted on next reboot recovery.

    how to operate: MENU/VOL- = next(down), SEARCH/VOL+ prev(up), HOME/POWER = select, BACK = back

    *1 if recovery is 3e, you can put it with any name on any directory in SD card
    *2 some tablets/roms mount internal storage as /sdcard. confirm update.zip exists on root of SD card.
    *3 some tablets/roms have system update function in Settings to install update.zip


    * How to install ClockworkMod Recovery 5 (alternative)
    a. flash recovery.img in recovery.zip by fastboot (if your tablet has fastboot mode)
    b. flash recovery.img in recovery.zip by flash_image command on root shell
    c. flash tcc_mtd.img with clockworkmod recovery.img by FWDN

    you may need to delete /system/etc/install-recovery.sh before install (if it exists on your tablet)

    * How to install CyanogenMod 7
    1. install ClockworkMod Recovery 5
    2. reboot recovery
    3. make backup of stock ROM
    4. wipe data/factory reset *4
    5. install cyanogen.zip
    6. reboot
    7. touchscreen calibration *4 *5

    *4 only if you are upgrading from non-CM7 ROM (CM7 1st install)
    *5 only if you are using resistive touchscreen or misaligned capacitive touchscreen. if calibration is not needed, press BACK to cancel calibration.


    * How to flash FWDN image (Windows PC is required)
    i) prepare
    1. download FWDN_V7_v2.13.exe
    2. download & install VTC Driver v5.xx for your Windows PC
    3. download lk.rom and tcc_mtd.img for your tablet (DO NOT USE FILES FOR OTHER TABLETS!)
    4. connect power cable (do not use USB power for safety)

    ii) flash bootloader(lk.rom) you can skip this step if you already flashed proper lk.rom or you don't have proper lk.rom for your tablet
    1. start FWDN on PC
    2. drag & drop lk.rom into FWDN window
    3. (re)boot tablet into FWDN mode
    4. connect PC and tablet (window popped and size of "NAND Data" is displayed in Area Map in FWDN window)
    5. confirm checkbox of lk.rom is checked
    6. click "Start" & wait complete
    7. disconnect & reboot tablet into FWDN mode to use new(just flashed) bootloader
    8. uncheck checkbox of lk.rom (it's ok if checked but no reason to flash again in next step)

    iii) flash Android image and initialize internal NAND(FAT) partition
    1. drag & drop tcc_mtd.img into FWDN window
    2. (re)boot tablet into FWDN mode (if you forgot it in 7. in previous step)
    3. connect PC and tablet
    4. click "NAND Data" in Area Map in FWDN window *6 *7
    5. fill "Image File Path" (use [...] button) *8
    6. click "Create Image" (NAND Data.fai will be added in main FWDN window)
    7. confirm checkbox of tcc_mtd.img and NAND Data.fai are checked
    8. click "Start" & wait complete (take several minutes)
    9. disconnect & reboot tablet

    *6 creating new NAND Data.fai is required when size of NAND Data(FAT partition) is changed by flashing new lk.rom in previous step. you can use same NAND Data.fai if you are using same lk.rom. don't use NAND Data.fai from other people.
    *7 if size of NAND Data is not changed, you can skip flashing NAND Data.fai to keep your files in NAND(FAT) partition.
    *8 you can make non-empty NAND Data.fai in this window
    8
    * issues
    no mic input with stock apps
    USB host on Scroll 7" resistive and 8"
    USB mass storage mode (mount from PC) under some condition
    some USB mouse
    suspend/resume on Emdoor's tablet with Eclair ROM (a-rival PADs, EM51, and EM71 multitouch)

    * tips
    - what is lk_androtab.rom? / how to increase size of /data?
    use lk_androtab.rom in FWDN.zip. in lk_androtab.rom, size of partitions are modified to get more /data. in addition to this, lk.rom/lk_androtab.rom for COBY Kyros MID7015/7016/7022 and EM73 capacitives have +512MB for MTD(assigned to /data) and -512MB for NAND.

    - how to use internal NAND flash as SD card?
    Settings -> CyanogenMod settings -> Application -> Use internal storage -> On -> reboot
    if enabled, internal NAND flash is mounted on /mnt/sdcard and SD card is mounted on /mnt/nand.
    in clockworkmod, internal NAND flash is mounted on /emmc. it will be used by "install zip from sdcard -> choose zip from internal sdcard".

    - I like portrait / my favorite portrait apps are upside down / accelerometer axes are wrong on some apps
    make /data/local.prop with following 3 lines, then reboot.
    Code:
    accelerometer.hwrotation=270
    input.hwrotation=270
    ro.sf.hwrotation=270

    * FAQ
    - what is GB ROM?
    old TCC8902 tablets were shipped with Eclair ROM, but there is GingerBread ROM for some tablets. bootloader(lk.rom) and kernel in GingerBread ROM are not compatible with bootloader/kernel in Eclair ROM. CM7 for GB ROMs only work with bootloader in GB ROM, so you need to install GB ROM before installing CM7. (you can use CM7 FWDN image as alternative)

    - what is 4K/8K?
    there is 2(or more) variants for some tablets. they have different NAND, pagesize are 8192 or 4096, and it may need specific kernel for each.
    HY means Hynix, and S means Samsung.

    - touchscreen doesn't work (EM71/73)
    there is many variants for EM71 and EM73. check your tablet carefully and use proper file.

    - touchscreen calibration doesn't run on 1st boot
    try run manually
    Code:
    am start -a android.intent.action.MAIN -n org.zeroxlab.util.tscal/.TSCalibration

    - I want to do calibration again
