relive bricked OEM CUBE RK3066

Hi,
I need some help with unbricking OEM U9GT3, also known as D97/97S. This is chinese clone tab with RK3066.
I had some issues with battery, so I tried to flash various ROMs. After I flashed ROM from NextWay tablet my device died.
Literally died. No response to POWER, USB, Charging. Can not put it into recovery. Obvoiusly PC doesn't see it.
I found a tutorial about unbricking WINDOW 70dual, but it says something about the contacts on the mainboard. After I opened my tab I can not find that were mentioned.
I tried also another tutorial adviseing to shortcircut 29 and 30 pin on one of the chips. It didn't work either.
I replaced battery. It didn't change anything.
The most important now is what to do to a tab to make it visible for PC. I can manage with the rest.
I can provide photos of mainboard or any further information if needed.
Any idea is very appreciated.
Mark

hi
has blocked the tab .... happened to me several times with my pipo s1 .... how to revive it is simple .... you have to put the original ..... firm or .... firm that you know works .... Once done ..... remove the battery for a minute and then reconnect the battery .... normally turn the tab ..... supposedly should work .... flahear remember before the rom that works .... delete ID

Yeah well cool advice.
But how can I possibly flash ROM that works when my PC DOES NOT SEE the tab? If I could flash anything I would do it.
Question is how to reset tab to erase nand flash and flash new rom.

never flash DSP_BL and preloader. as long as the device is recognized on your PC, its not "dead" othewise you can try the "testpoint" methode, but not all motherboards have one.

[Q] Thunderbird i5 - bricked and RIP

Hi folks,
I recently bought a Thunderbird i5 dual core - mtk6577 at cect-shop.com .
As far as good, dumb as I am, I tried to flash a pure android rom of colonelzap.
Since then, the phone is completely gone. The screen is dead and I can't hear anything, that the phone is booting. When I push the power button and the phone is connected to my pc, I can see, that the usb vcom drivers are loaded properly. So I guess its still possible to flash a correct rom.
I contacted the cect-shop.com team last week and the advised me to open up a thread at chinamobiles.org - sadly no appropriate answers yet.
Does anybody have a stock or custom rom, which is supported by the Thunderbird i5?
Or better said, is someone able to help a damn noob to unbrick the phone and to bring it back to life?
I appreciate any hints.
Thanks,
Maik

Spreadtrum SC8810 MT6515 dead (urgent solution needed)

I rooted it which was absolutely fine but I tried to flash a custom rom onto it. I'm not going to lie I had no idea what this involved, what the risks were there , even I flashed it.
Anyway during the installation of the new Rom seemed to be going fine with Research Download and after finish installing it was just died. Since then i cannot get it to turn on and it just doesn't power up. It also won't charge now.
also when plugged into the PC it does not detected , so I'm hoping the fact it's still recognized as something means there may be some hope left.
plzzzz friends tell me what i do,
I have no idea what I'm doing, I am just here with my lovely new phone not turning on.
some persons have given idea of doing heating of the Processor IC / Processor Chip because of Boot failure , but how i do this process.
help me friends now.
Thanx in advance
