Hacking Question Switch only shows blackscreen ofw/cfw

[Hyperfluffy]

Hi everyone, I have the following problem with my switch.

What I had:
First generation switch with FW 9.1.0 / Atmosphère 0.10.2 / 400GB Fat32 SD Card / AutoRCM on / no emummc.

What happened:
A week ago all was fine and i shut down the system because wasn't using it for a time. Yesterday I tried to boot it with turning it on, AutoRCM, and then pushing the fusee-primary.bin. My dongle showed me it was pushed but the screen stayed black. I pushed the hekate payload and hekate showed up as normal. Tried the fusee-primary.bin again, but nothing still a black screen. I then turned Auto RCM off and tried to boot the ofw but I just also got a black screen. Thats all I get so far when i try to boot cfw or ofw.

What I tried so far:
- new and old versions of atmosphere
- other sd cards
- exfat sd card or fat32 sdcard
- recovered nand (Raw + Boot 0/1) to 6.2.0 and even 8.1.0 from backup
- created emummc from sysnand and also from backup for 6.2.0 and 8.1.0
- all the above in combination over and over again

What can I do to try to find out what is wrong or maybe even fix it?

What does you battery percentage say in hekate

 

[Hyperfluffy]

90-100% and it is charging with around 400mA
I also thought at first it is a low battery but unfortunately not.

anyone an idea?

Tried the fusee-primary.bin again, but nothing still a black screen

What I *can* say, is that injecting the fusee-primary.bin is something I need to do TWICE before it works.

Usually:
1) RCM'd Switch to PC -> inject Hekate. Start .bin
=> Switch gets stuck on black screen after switch logo
2) Hard turn off switch via "12 Seconds hold power button"
3) Repeat. This time Switch just boots.

I prepared an emu nand as outlined here, so not sure if this will work for me.
But thats been the "switch experience for me so far".

Maybe that'll help.

My FW: 9.20, CFW: Atmo

Thank you for our respond. Unfortunately no success. I ordered a new NAND chip from china. Maybe my is faulty.

BTW:

Try another (freshly formatted) microSD card and put only (a newly downloaded):
- atmosphere
- bootloader
- config
- sept
in it.
For example
use this one: https://tinfoil.io/Download

Then see if it boots.
I had my microSD files be partially be corrupted by a program some days ago.
And naturally the switch wouldn't boot. (As Emunand is stored on a microSD partition).


Also important:
Connect your RCM Dongle to your switch and look at the light color.
If it is "white" it might be that our switch is stuck in a /between mode/.
Hold power for 12 secconds until the dongle's LED turns off too.
(Pretty nifty to have this as some kind of power draw indicator)

Even try disconnecting the battery, mine black screened and wouldn't turn on until I reconnected it

Hi Everyone... so I received a new emmc chip today and inalled it. After recoverying it shows the same black scrren when trying to boot into cfw/ofw. Also tried SXOS (not working) and ReiNX (sows package2 magic invalid).

The ReiNX error seems to show that something is not readable because I was using the newsest build.

What is this package2 all about?

When I have a look into sourcecode of ReiNX it seems that package2 is pkg2 ?!
