Looks like I've bricked my Goclever T73
I've installed cyanogen from this thread before without any problem but now it's not booting anymore.
System is working, but screen is black and when I connect with adb I can see that processes: zygote, system_sever and miediaserver are being killed and restarted every few seconds.
When I try command: "reboot recovery" it just reboots the same way and stuck.
Is there any way to force reboot into recovery? Then I could restore system from backup.

Edit:
I was able to reflash boot and recovery partitions and now my tablet is back

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
Hi fun_ & co
How can I get back to stock recovery on a Scroll 7" 51624 ? I have ClockworkMod Recovery5 installed and dumped_recovery.img plus dumped_proc_mtd.txt saved safely on the PC and SD card but I am clueless how to proceed. The downloaded scroll-51624.zip firmware from Storage Options will not load from ClockworkMod Recovery 5. I just want to restore the tablet to factory settings. Any help would be much appreciated.

hello!

i have a GoClever Tab T73 and i use the Dropad D10 files
i installed ClockworkMod Recovery 5
after the instal it went automaticly to Recovery
and there i instaled the CyanogenMod 7.zip from the sd card
the instalation wentsuccessfully and the Operating system turned on

at first the touchscreen didnt work,but after a couple of seconds the application of the calibration started automatically
and then the Operating system worked fine

but afterwards i accidently turned on the calibration application
and from that moment the touchscreen is not calibrating and im stuck at the "home" screen

i tried to enter the ClockworkMod Recovery 5 to do restore to the old system , but i couldnt managed to get in (maybe because i didnt press the right buttons)

then i tried to flash the ClockworkMod Recovery 5 again through the FWDN but i dont know how to enter to FWDN mode

Thanks in advance for any answers

Default Kogan Agora 10" tablet touch screen and menu buttons not working

Hello,

Just followed the instructions and flashed my Kogan Agora (with the Emdoor EM73 capacitive GC2M 8K ROM). I was able to boot into android but the touchscreen doesn't respond and neither does the menu or soft back and menu keys.

When I boot into Clockwork mod and do a key check it says that no key is pressed when I press the menu button HOWEVER I need to press the Menu button to get into CWM so it is obviously still functioning at a hardware level.

Does anyone have any advice on what I could do to rectify this?

if my memory is correct D10 has no key to enter recovery and/or FWDN mode.
please try "adb reboot recovery" and "adb reboot bootloader".

there was a issue that data on internal NAND flash is corrupted easily without any reason. it should be fixed at some point. if you get same issue repeatedly, please tell me again.
(but I'm not sure I can get time to fix (any) issue, sorry)
