Is there no way to restore the machine?

用的join_15_2GBparts_windows 是不是需要返厂了，黑屏进不去系统

Join _ 15 _ 2GBparts _ windows need to return to the factory, black screen can not enter the system

What you did was a restore of 1 of the 3 physical partitions.
You need to also restore BOOT0 and BOOT1?
These are essential to do a FULL restore.

The black screen you are saying, is probably from incompatible rawnand.bin and the current BOOT0/1 you have.

So, copy the BOOT0 and BOOT1 backups you did, to /Backup/Restore and run the option "Restore eMMC BOOT0/1".

Rajkosto's tools can help you in nand restoring :

1. Use gptrestore payload to fix gpt table.
2. With HACDiskMount extract all parts of your rawnand.bin (Use your dumped biskeys : can be dumped by using this payload ).
3. Use memloader to put your switch into USB eMMC UMS Mode.
4. With HACDiskMount with admin right, open your eMMC nand by opening device Linux UMS Device 0, and restore all extracted files from rawnand.bin by using biskey too.

Why filling in key fails

Can you start the recovery mode pressing power + vol+ + vol- ?

@luhongtao
Check that you got your BIS keys correctly.
This works great here.

[luhongtao]

Can enter rcm. system 3.0.0 can not restore firmware, restore the end of the black screen, you can now view the biskey

You tried to launch firmware through hekate?

[luhongtao]

If you want to resume booting, you will not be running the system on the black screen at the moment.

In the end, because this is not an actual issue with hekate and here is not a support forum, I'm closing this.
