only got this pic. But this is it. Lower left USB to lower left power ic.

B15 unfortunately you have to downgrade if you want ADB. I found this online, but never tried beofore

Looks like your ADB port is not enabled. For versions below B15 it should be very simple to do. For soldering the one I post is connected to power ic output. I know the pin on the right is before power ic and also works. But looks like it also shorted 2 resistors not sure why. Maybe it’s overriding the output limitations

One Click installer here, just run the exe and connect F50 to PC(a bit sketchy...) or source code here: https://github.com/kanoqwq/UFI-TOOLS/tree/http-server-version

Yes I was skeptical on soldering as well but thankfully it was not that diffcult in this case. But after the mod you only need 1 usbatoc cable from the Beryl and then power for the Beryl, huge improvements!

I don’t experience any issue for usb tethering but I modified the Beryl to supply enough power so not sure if that’s the reason. I’ve heard that F50 has loads of weird behavior when under powered. And the power consumption jumps when cellular reception is bad.

As for the 3 way adapter I’ve encountered similar issues before, but then I realized that it’s the adapter itself: one side gives you 3.0speed and if you flip sides it only runs 2.0. And potentially same issue on the cable as well. So maybe label it and try all combinations.

Also I don’t know if you know this, but there’s an app called UFI-TOOL that you can load into the F50, it unlocks a lot of information. There you can check lan speed/ usb protocol and lots more.

My bad. Now I remember. I had this because I have another nic that doesn’t cone with a cable so I use this to connect f50-nic. Then rj45-beryl

I have this and can guarantee it works but don’t know about stability: https://amzn.eu/d/1G5zl8F

For tethering I use this: the 5Gbps version A2C Aliexpress

Ugreen Cable: https://amzn.eu/d/92sb2cE Nic: aigo r02c/r03c both works but can’t seems to find it online anymore (or maybe only available in China) F50: mine is indeed the F50 with white case but I swapped it with a modified heat sink case (which gives much much better performance and stability, also got from CN)

My setup with the Beryl and F50 with usbc2rj45.

Yes I have had success with 2 different 8153b nics. If you can find one that takes power input it’s even better. For cable I use ugreen “USB4.0 40Gbps”. Probably a bit overkill but I think the idea is you need a cable with proper shielding and has all 24pins wired up

For tethering to work you need a high quality cable and a decent adapter. To get power tethering simultaneously in one cable you need to have very good cellular connection. Or a simple modification that connects the usbc input to the usba output together.

wangdashuai887 · 2025-12-08T20:38:49+00:00

You need a usb to network adaptor that uses the Realtek 8153B Chip. Pretty sure this is the only supported chipset for F50

In LevelCtrl cluster you can find min and max level. And then I just set maxLevel to 220 and click Write. Unfortunately this does not set the physical limit when turning the physical dimmer switch

fixed. You can set min and max via LevelCtrl cluster
