Is my dongle deffective ?
The deffective rate on Xecuter SX Pro is ~0.1%, 9 times out of 10 it's some mistake from the user side...
Overheating - If your SX Pro dongle seems to overheat, the correct test is to leave the dongle for at least 1 minute unplugged from anything. Use the SUPPLIED micro USB cable to then plug into pc USB port and wait 10 sec. If there is no green led then try unplug and replug USB quickly and see if led lights up. If no led then we will have to replace your unit.
Please note you must not use another USB cable as a low quality or long cable can cause a microprocessor crash which will in fact cause overheating.
With autoRCM it will appear the console is not turning on unless you have the SX Pro dongle inserted.
If you have it in and its still not working, then it is either that the sx pro battery is empty (charge via microUSB port on sx pro) or that the Switch battery is empty (charge using Switch charger).
The dongle will take ~10-12 seconds max. to charge. The light on the dongle will be green once its charged.
With autoRCM if the dongle is not charged, you MUST charge the dongle first, else you cannot boot your switch. But it is important your switch battery is not empty as well, of course.
If you get black screen, and the light turns green on the dongle, it is most likely a user mistake when installing. It can be several reasons, hard to guess.
Probably yes... there are logs in the consoles so it can be detected by official service staff. Currently there is way to clear it using other payloads, it's on request list to add it into sx os. BUT even without that, they it 's probable that it can be detected when in rcm mode.
If you have SX Pro do not try to injecting and booting connected to pc. The SX Pro dongle has the payload.
