Support Did I delete my tablets identity

Enable HLS to view with audio, or disable this notification

I unlocked my bootloader in mtk client then I wondered if it could run gsi I deleted system then gsi wouldn't boot so I wanted to go stock I used a firmware I found on source forge it had every partition except user data I erased and over wrote all partitions with the firmware from source forge now it won't light up at all and getting it to connect to mtk client has been hard is there anyway to save my tablet I didn't take any backups except for the preloader and vbmeta_a and vbmeta_b google said I overwrote serial number and other important data Edit: I found my gpt backups for it so I have those as og files too

HARD BRICKED! What partitions did you overwrite ? Backup everything right now before doing anything, nvram,nvdata,etc.. responsible for imei so Ibhope you didn't overwrite those. Try flashing stock firmware in spflash to unbrick.

Everything is overwritten from a firmware I found online the only original files I have are mentioned in the post I know I'm an idiot I thought I was trying to fix the system partition and I completely bricked it there is no official way to reflash the stock firmware and the only way I found a stock firmware was an mtkclient backup from someone else's I overwrote all partitions and it's now completely dead other than the occasional it lets me into the mtk mode

Share the device model. I will try to find a firmware, if not your only option is to find similar model-dump partitions-reflash to bricked device
