Got a really messed up USB port on one+ year old Razer 2

1) Can't charge while it is in normal mode.
2) Can't charge with USB C to C
3) Can only charge using USB A to C, while the phone is turned off. It still splashes the logo and vibrates repeatedly.


The port is not visible to any laptop, so adb and fastboot seem out of the question.

The stock recovery on this device has "apply update from SD card", so I need to figure out how an update.zip should look like.
Razer have a bunch of older stock ROMs on their site.

Can I just take the latest, rename it update.zip, put it on a micro SD and use the stock recovery to fix things?

    Just saw the tear down. It's worse than my N10+ port PCB to replace.
    However if the battery is getting near its lifespan maybe now is the time as the battery needs to come out anyway to replace the port PCB.
    The port PCB price is probably low.

    The other thing I just found is that when I use "apply update from ADB" it used to complain about init.usb.rc, init.usb.configfs.rc. I looked at both files. 0B length with 1969 date on them. What?

    There must be some way to flash a recovery from the sd card instead of using the USB port.

    The thing is the battery held the whole day after a night charge yesterday, so probably not the battery. I have a feeling some apps I used to "improve" the battery and "fix" the system deleted some bits.

    If you have a bad usb port PCB I would replace it now.
    They can cause a lot of mischief and in other services that you never expect it to.
    The battery is cheap so it's easiest to replace it at the same time as you need to pull it anyway.
    200 or more full charge cycles, replace.

    One more thing. I bought a wireless charger to see if it is 100% the port, and the wireless charger has not made anything easier. It seems not capable of getting any charge in. So at the moment I have only one to charge it, turn it off and use USB A to USB C cable.

    Probably a defective charge port PCB... you can try a factory reset or reflashing the stock firmware if really want to test it.

    Check for any signs of battery (rear panel or display bulging) swelling; replace battery asap if present! Batteries can fail at any time.

    I have now done the factory reset, didn't help. Nothing is bulging. I would like to flash a fresh factory ROM, but I have no access to the port. So, no fastboot and no adb. I can't even install proper drivers in Win10 PRO since the laptop does not recognize the phone, at all.

    I am searching now for any solutions with the sd card. People used to do that, updates with *.zip on an sd.

    Since it is out of warranty anyway now, I have finally unlocked the bootloader.

    I am trying to find out if the ROMs Razer provide on their site are signed or not.

    The port PCB needs replaced... if you're lucky that's it.
    Don't make it harder than it needs too be...

    I don't know if you have had a chance to see the USB port assembly on Ebay? Some prices are close to $120. Add to that labor costs (unless you think I should do the deed myself) or costs for tools and fresh adhesive for the plastic that covers speakers, etc... and it is going cost me more than I paid for it new.

    Ok, thank you for finding this, but it looks like the ribon connector wire only. The PCB besides the port also has the microphone, I think. It appears to be sold as a unit. If the problem is the wire, then sure this would be the part.
    In any case, I have managed to get the wireless charger to charge. Depending on how fast the charge will be lost today will tell say something about the battery.

    I'm just saying keep looking. I was surprised at the apparent lack of availability though.
    Meh I feel your pain...
    Maybe one of the mainstream parts venders or buy a cheap Ebay one with busted display.
    My Note 10+'s port PCB goes for $20, that surprised me.

    Unfortunately replacing the USB charge board and port in the phone doesn't always fix it. I have a box of nearly a dozen RP2 main boards I need to dig through to figure out what the actual cause of the charging boot loop

    Have you played with any OS shortcut apps on it?
    The Android Setup apk will get screwed up if you access it after the original setup.
    Specifically it will alter the port behavior when you connect with it. Very irritating, took me days to finally track it down on my 10+

    If you clear it's data in settings it may leave the null mark that's screwing it up. Some 3rd party apps can completely clear that null mark.
    Otherwise factory reset.

    This is a hardware issue, nothing any kind of reset can fix or app clearing. Even if you have the device entirely powered off, plug it in on anything 2Amp or higher, it'll loop

    That's not how the issue I saw behaved; only happened with the device powered on and it didn't boot loop. Just an annoying pop up message.

    If it has a port PCB, try replacing that. If it's just a charge port with no components on it... it's likely either corrupted firmware (reflash) or a mobo failure.
    A loose connection or bad contact is also possible.
    That's my guess...
