Please can you explain how to use that firmware?
I think it's a recovery firmware for going back to factory defaults when s**t happens.
But I read on some forums that I should backup my IMEI and NVRAM (with MTKDroidTools or something like that...i don't know if there's a specific tool for the Cube T8 Plus) BEFORE trying custom roms, otherwise there will be problems even on restoring stock firmware, right?
Can somebody please make a short-how-to for dummies focalized on this Cube T8 Plus (so poor and confused support on forums yet)?
- Backup before custom rom installation
- Custom rom installation
- Recover to stock firmware
Another question: why that page you linked says "Platform: Mediatek MT6753"
Isn't MT8783?
Thank you very much

my tablet is not bricked now but my serial number and my mac adress is wrong ='(
Use sp tool for save your firmware tablet ( i think).

I have the same problem, after the resizing of partition the tablet is soft bricked and I'm downloading the stock firmware form the above link.
Is there any way to backup the mac address and serial number from softbricked tablet?

...you should have a backup of nvram!

I think it's too late.
I did a backup of nvram with SP Flash Tools BEFORE brick.
When i recovered the tablet after brick, my IMEI was invalid until i flashed my backup of nvram.

Anyone could suggest how and what to backup before trying Root and Resize?

Just backup nvram with sp flash tool

The only unrecoverable partition (for mediatek devices like T8 Plus) is the nvram which contains info about IMEI.
Firmwares/ROMS that we can download from the web never comes with nvram because it's single product related. It's like mac address of wifi cards.
You can find even stock (original) firmwares online, they will bring your tablet back to factory default after a brick.
But if the brick corrupted the nvram, you will NEVER be able to recover it. That means no phone calls and no data connection.
Unless you did a backup of nvram before its corruption.
With SP flash tool you can "read back" from your T8 plus the nvram partition and save it as a file on your pc (file size must be 5MB). Of course you need drivers, SP flash tool and the scatter file. Since i wasn't able to retrieve the scatter file from my T8 plus, I used the scatter included in the stock firmware T8-PLUS_V1.0_20151004.
I am new forum user so I can't post links, but google is enough.
That stock firmware is hosted by baidu, so use browser translation and register an account to get permissions for download.
Remember: in the firmware archive you only need the scatter file! It will tell to SP flash tool where the nvram partition starts and where it ends.
If you will need to restore nvram (e.g. after the unbrick) ,you will have to download to your T8 plus that nvram file with SP flash tool, but before you have to edit the scatter file and set "is_download=true" in the nvram section. Otherwise you will not be able to select nvram in the partitions list from the download tab of SP flash tool.
So the backup will consist in two files:
- nvram file (5MB) (nvram, nvram.img, nvram.bin, extension doesn't matter)
- scatter file with edited "is_download=true" for nvram section

Thanks so much for your help. I think i will be able to backup NVRAM. But im kind of lost on scatter file editing and flash.
Im waiting for Tablet ti arrive
