Hello there,
I bought a used Switch in order to try to fix it. The seller told me that this switch failed to a software upgrade.
Here is the situation :
No autoRCM
15 fuses burnt
USB-C port is fine to communicate with the SOC through D+ and D-
Battery voltage at 4V
eMMC readable and writable, benchmack via Hekate is good
LCD and touch Panel are fine via Hekate
SD card reader is fine to read and write my EVO SD card from Samsung
Fw is 10.1.0 with Tegraexplorer
There is absolutly no problem to use this switch with these payloads :
Hekate is able to read and write my SD card, backup and restore my eMMC
Tegraexplorer, Lockpick and biskeydump are able to backup keys
At the beginning i thought that it was just a mismatch between 15 burnt fuses and a 10.1.0 firmware so i follow a guide from suchmememanyskill to upgrade then wipe to firmware 13.2.0.
Unfortunatly i’m still stuck on black screen when I power up the switch. So in order to know if it’s a software or a hardware default, i decided to install Android on my SD card.
There is no problem to install Android with Hekate but when the switch reboot for the first time to TWRP there is still a black screen.
Same issue when i use an EMUNAND with Atmosphere, i only see the splash screen of Atmosphere then again a black screen …
If i’m unable to boot on Android and genuine 13.2.0 firmware, it must be a hardware failure but i’m unable to guess which parts fail inside this switch.
Thank you for your help.
