Please help to unbrick a Cube u27gt s tablet - Android Q&A, Help & Troubleshooting

Hi guys,
I just bought two brandnew Cube U27GT S (MTK 8127) tablets and tried to install a custom rom. Unfortunately the tab hard bricked while trying to flash it with SPFT. Now I can´t turn on the tab anymore - all black. I even can´t open the recovery mode and Win 7 doesn´t found the tab anymore, it shows unknown device in the device manager!?
Meanwhile I deinstalled all MTK drivers with usbdeview and installed them again with the help of the second tab. But it has no effect of the damaged one it´s still an unkown device.
Maybe anyone has an idea how to unbrick it? Would be great to get any help! :crying:

No hope anymore?

I have the same problem can only get into recovery, factory reset does seem to do anything still hangs on boot, looks like I need to update via sdcard?

Hard bricked : Karbonn smart tab 10 ( st10 )

Device : Karbonn Smart Tab 10
Problem : Hard Bricked
I have been trying to upgrade my ST 10 to custom rom available in this forum. But after update, tab was stuck in Red Boot Logo Screen. Then I tried many things but no success. Finally something went wrong and not device is not even responding to power switch.
Then I found on google that AMLOGIC flash tool can flash and restore tab. By hit and trial methods ... now i am able to connect my tab to PC and AMLOGIC flash tool detects it.
Device Manager of my Windows7 shows Tab as WORLDCUP DEVICE. But I am not able to go further from here as I dont have correct zip with some config xml file.
Please help.
Maybe I am using wrong software to flash (AMLOGIC). Then suggest better one along with files required.
Please Help !!
(Bump)
Karbonn tab 10

Any luck?
Hey, my younger brother bricked his ST10 recently... Any luck in unbricking it? I can't even get to installing the drivers so that the tab shows as worldcup device in the device manager... I can only see Android ADB interface in the device manager (Running windows 10) and in Devices and Printers I see the device as "Velox"...
Hi, were you able to find any solution to your 'deep brick' of Karbonn S10? I'm facing the same issue with my Karbonn tab-8 velox.

Help ! Lenovo tab A10-30 hard bricked

First of all, sorry for my bad english. My problem started when i deleted accidentally one partition of the tablet, trying to make an working twrp for it. Now I have no adb commands, no recovery, no fastboot,no logo,no display light. Nothing works. Just an expensive brick. PC only see something like "diagnosis 900E, instead of USB QDLoader 9008,so QFIL can do nothing to fix.I have changed driver,now can be seen QDLoader but QFIL gave me errors. I just bought another tablet, same model, for my son. I will try to pull out system, recovery, boot etc. But after that...? Any chance to make an bootable microSD card with those files? Any advice please?

These tool unbrick your android when no fastboot, no recovery, not booting by anyways. Just detects in 9008 port. I am sure it's better than Qfil.
That`s the problem with port detection
