Doesn't help how it looks. When you bricked it you need to open it anyway to bring it into flash-modus.

Ok, so kernel R70DC should be the right one. http://crewrktablets.arctablet.com/?wpfb_dl=1715

Try again using this method to start the tab into mask-rom modus :

Oma, thank you so much!

ok, I do all as in your video

so, I set bricked pad into maskrom mode, check mode by AndroidToolkit 2.1, then RKDevelopTool_Release_Pack_v1.37 - both says something like "Found one MASKROM device ..." and then I press "EraseIDB", and erase it success

then I run Rockchip_Batch_Tool_v1.6, but I don't have firmware image file, so I try to flash it with

R70AC_3026(英文中性_KID)_NAND_IPS1024600_GC03112(前30W后30W)后置插值200W-RDA_V1.1_V20140401.img 974mb image, but unfortunatelly, when start flash, the pad switch into Loader mode, flash complete success, but pad still bricked, just black screen, when I try to turn it on...

all my troubles started from flasing this R70AC ... .img

do anybody have working R70DC firmware image?

my flashing Oma_RK3026_Roverpad TRC7_JB_4.2.2_v1.0.7z + RK3026_kernel_3036_r70dc_apad.7z by RK3028ALoader(L)_V2.08.7z in included RKAndroidTool 2.1 does same result - black screen brick

I connect pad in MASKROM, then select 2.08 loader, then LowerFormat pad, then try to flash it

when flash starts, program shows me switch into Loader mode, then shows that's everything fine, flashing complete success, but after disconnect and try to turn it on - nothing (((

 

the only one working thing I learned do - flash it with R70DC_cwm.zip from google drive from this page

http://forum.xda-developers.com/showpost.php?p=51594282&postcount=115

so I have working CWM recovery, I can boot into CWM mode, but nothing to flash with it

When you can boot into CWM we have a working kernel. Here is the kernel from that zip: http://crewrktablets.arctablet.com/?wpfb_dl=2334

Try again.

nothing for good news - I flashed pad with your firmware Oma_RK3026_Roverpad TRC7_JB_4.2.2_v1.0.7z, using 208-Loader and kernel from googledrive zip cwm, that's can be downloaded from http://crewrktablets.arctablet.com/?wpfb_dl=2334

no logo, nothing on screen...

try to flash with working recovery so I be able to boot into CWM?

or this helps me nothing, because I don't have full firmware image?

CWM won't boot without working kernel. You should see a kernel logo before CWM starts. What stuff do you use exactly?

ok, I LowerFormat and flash it again with Oma_RK3026_Roverpad TRC7_JB_4.2.2_v1.0.7z + R70DC_cwm.zip using included RKAndroidTool 2.1 + RK3028ALoader(L)_V2.08.bin, flash in Loader mode was complete success

when I press vol+ or vol- and power = it boots into CWM, here kernel logo here CWM main

vol keys shows highlight bar movement in each second time, as described in xda topic, i.e. reboot, install from sideload, wipe cache ... and so on ...

but in normal mode it won't boot (no matter - from CWM or just by press power key) = just black screen

maybe problem is in flashing offsets? I means recovery.img written in correct offset 0x00012000 and CWM works fine, but kernel.img must be flashed in 0x0000?000 instead of 0x00004000, or boot.img in 0x0000?000 instead of 0x0000A000, or system.img in 0x00?????? otherwise 0x00484000
