So a few last questions (between the lines) because I got another Tolino to flash your ROM:

Your decription is ... :

connect your tab to the power supply and to the PC via USB cable

1) installation of the usb-driver (skip if you have the driver installed already)
     a) boot your tab and set storage mode to MTP and debugging to USB
     b) run DriverInstaller.exe

2) start the tab into flash-modus
     a) run RKAndroidTool.exe with admin rights
     b) press power button and volume up button and hold for 12 sec
     c) release the power button
     d) release volume up button when "Found ..." is shown

3) flash the firmware with RKAndroidTool
(you mean the set of images: kernel, boot, system... what is as standard in the flashtool setup ?)
     a) untick the loader
     b) Run
     c) stock recovery will format the NAND
     d) wait up to 20 min

After this step the tablet boots normally last time I did this with the bricked one. Now the icons where much smaller.

This is the way it should to be ? Then I do a reboot with the following steps (4) and always untick the loader, too or not ?

4) flash the CWM recovery with RKAndroidTool
     a) go to app drawer, open RebootMenue and Reboot to Bootloader
     b) untick kernel, boot, system
     c) load recovery_CWM
     d) Run
     e) tab boots into CWM
     f) reboot system now (both answers are No)

Can you describe the last part (4) with more details, please ?! I'm very afraid to kill the next Tablet

Thank you !

Thanks a lot !

My new tablet runs with the OMA 1.1 now.

I can see an update of 11MB (V01.01.03). Should I install it ? I tried it out but get an error during installation.

Hi, this is my first post.

I've probably messed up by leaving the loader checkbox ticked in the RKAndroidTool application. The reason I did this is because I could not flash recovery_CWM from within that tool, though, in retrospect, I should have flashed it with the apk or some other tools.

Anyway, like one user before, the tablet is now dead, erase IDB does not work properly and all flash operations fail with 'download failed'.

However, unlike anyone before, I did manage to get my tablet to boot into maskrom mode, by randomly shorting pins next to the Samsung NAND chip. I've started the refresh tool, tried to flash 1.20 and 1.24 loaders but was not able to get anywhere.

The tools shows this:

******EraseFlash action******
Download boot start
Download boot success
Wait for Maskrom start
Wait for Maskrom success
Test device start
Test device Total(0), Current(0)

The log file shows something similar:

23:19:30 798 Rockchip Development Tool v1.7.1.0 start run
23:19:37 805 <Layer 2-1-3> Download Boot Start
23:19:39 764 <Layer 2-1-3> Download Boot Success
23:19:39 766 <Layer 2-1-3> Wait For Maskrom Start
23:19:40 876 <Layer 2-1-3> Wait For Maskrom Success
23:19:40 878 <Layer 2-1-3> Test Device Start
 

Then the tool just sits there at 0/0. Not sure what the correct output would be. I've tried erase idb, erase all and download loader in all possible orders. After launching one command, the tool cannot launch another one as it says it's still busy.

Any suggestions?

The tablet was working fine before the flash. I've had one tablet with a bad flash chip and it would just get slower and slower while refusing to copy files or flash. So I assume the chip is still fine.

Unfortunately the tablet is out of warranty since a week so I'm willing to try anything before selling it really cheap or keeping it as a paperweight. Perhaps there are ways to get the loader firmware from someone with a working tablet and flash that. I'm not sure what the recommended action would be.

Is the loader fw made for the flash chip - i.e. the microcontroller embedded in the NAND - or is it for some other parts of the system? I don't fully understand how these systems go together.

Sorry for the late reply.

I've just randomly shorted pins on the NAND chip since I had nothing to lose. I believe pins 9-10 are the ones triggering maskrom, counting down from the upper left corner:

Hi folks.                                

I bricked the tablet trying to flash the rom, rockchipdevtool recognizes the tab only in LOADER mode but cant restore or flash like the others.When i try to get into maskrom mode trying the pins my tab just turned on and i could use it normaly.After that i thought that the problem has gone away  i restarted the tab and now its dead again.Can anyone here tell me why this happened and did anyone found way to get it back to life???

Thx in advance and have a good one ,)

 пожайлуста обьясните подробно в каком файле менять запись и в какую папку вложить файл.спасибо
Please explain in detail in which file to change the entry and which folder to attach the file to. Thanks

im RKAndroidTool ist als "default" der Pfad zur Recovery aus dem Unterordner "rockdev" eingetragen, diese ist die Standard Recovery ohne CWM.
(Diese wird jedoch beim ersten flashen benötigt)
Danach muss du den Pfad zu der Datei "recovery_CWM.img" (Diese liegt im Rootordner des Zips) angeben und flashen.
Am einfachsten kopierst du die "recovery_CWM.img" in den gleichen Ordner und benennst den Eintrag im RKAndroidTool entsprechend um.
