Check Chip Fail error for RK3229 CPU

[ramkey4u]

I tried to update the os and tried this ROM downloaded from the link "https://mega.nz/#!8Yl1GQLK!yIdU2MXHf...8Up28d_mMTVxaM" from the post [ROM] Android 9.0 Alfawise A8 n the same forum.

After the update the system is not booting and no led as well.

I try to at least recover to old ROM, but I'm getting error message as "Check Chip Fail" in both AndroidTool as well as RockChip Batch Tool.

Can any one help me in this regard. I attach the screenshot of the upgrade tools.

Unable to attach screenshots in this posts. Can any one help me how to upload photos in this forum

I believe you used the bootloader they said it was not supposed to use 2.56 or something like that.

I almost got this ROM installed. Luckily the SDCard was not recognized.

"Android 9 from HK1 mini have bootloader 2.49 and send this firmware to the brick. Only bootloader 2.32, 2.37, 2.38 of firmware are good for Scishion V88 mini."

Not sure but I bet the ROM you used was this one.
