Hardware Emmc exchange without having a backup

[cherup]

I just have a faulty device and want to change the emmc storage.

I have successfully run biskeydump with the old defect emmc - so I do have all the keys.

- I guess the device keys will be still valid also for the new emmc ?
- Can I restore the system using the https://gbatemp.net/threads/how-to-...nofficially-without-burning-any-fuses.507461/ ?

Any other hints/tips how to go on here ?

nand backups are console specific, u will be bricked if u restore another consoles nand.

that was not the intention. I want to install the firmware from scratch with my keys using the guide and would like to know if this will work with a new emmc.

just use ChiorDejurNX or whatever

If it's faulty, he might not be able to enter Horizon to do that.

Following this guide should work if the problem isn't related to irretrievable console-specific files like prodinfo.

What caused the system to be faulty?

I bought a device which was not starting and it seems that this is because of an defect emmc (e.g. could not make a nand backup any longer).
So would like to change the emmc and create all the partitions new with my keys... in the hope that the console will boot again after that...

if its a faulty nand what would a nand img do for him

 

[cherup]

still not sure if a emmc can be exchanged in that way without a backup.
Could not find too much on that. Any more experiences with that ?

I mean, theoretically, with your biskeys, you SHOULD be able to construct new NAND system files using the ChoiDujour (not NX) guide that you linked, along with something like:

Most people here haven't really tried something as technical as that though, so don't expect definite answers. Unless you directly ask someone like @rajkosto

 

[cherup]

thanks for the help. Once the emmc arrived I'll give it a try and will report back.

Very interested on how this goes, I have something like this, but the eMMC is dead, I know the port is ok, as I can swap another eMMC in to the board while in recovery and then read the drive, however unable to read the eMMC thats attached to the board.. I guess I cant do anything with that. However I do have another Switch that wont boot, and id like to try to rebuild the drive to see if I can get that back to life.

Sounds to me like the nand had been corrupt by sxos anti crack, or another bad payload that bricks nand like one of my buddys used isnt that right @Mat37 , worse case is that it corrupt your prodinfo. And i think your well and truly fckd if it was that, all tho there maybe a solution im unaware of

you cannot change emmc modules without patching the prodinfo, and because each emmc module has a id ...
It is possible but takes alot of work and i do not wish to go into it, and you defiently do not want to either trust me..

May i suggest that you use memloader payload and hacdiskmount and backup what you can that way, by dumping each partition....

Then make a new image with choirdujour from systems files nx 4.0/5.0 etc

And then enter your system keys into new files and upload..


Backup first within hackdiskmount,
also recommend When you have a dump, you use the fw version finder tool so you know what system version to restore

Most people here haven't really tried something as technical as that though, so don't expect definite answers.

I have ... and i have done it via remote connection fixing member @Mat37 Switch With hacdisk method

I was not able to dump anything. I could backup Boot0/1 but when trying to backup other partition Hetake crashed - so I was thinking that emmc cannot be read any longer.
I have all biskeys saved from the original emmc.

Now hope I can replace the emmc with a new one and use the original device keys with hackdiskmount.

That's my hope at least.

Use hackdisk mount and run the memloader payload .... to backup your partitions
Does not use hekate this may or may not work

Or pm me and were use a remote desktop app and il bloody do it
