I recently discovered, that USB C to audio stopped working - using LineageOS 20.
Now I realized, USB to PC stopped working as well - even when booting in to fastboot mode, it is no longer possible to connect to the device because it will not be recognized any longer.
Also enabling ADB in LinageOS recovery does not work. When I try to connect the device this way, it will not even try to talk to the PC.
The only thing which is usable is USB-OTG, e.g. for USB sticks.
And yes, I tried different cables, ports etc. - other smartphones work just fine with the same cables at the same PC.
So I can not restore the device to the original âFairphone OSâ and I can not connect the device to transfer data via USB.
Any hints?
Edit: I already did a factory reset and reinstalled the latest LineageOS 20 version (using the recovery and a ZIP file I copied over first, since connecting using fastboot does not work any longer). But USB still does not work to connect to a PC - neither for file transfer, nor fastboot.
Iâd have guessed broken USB port on the phone. But if I understand you correctly then USB-OTG still works with the phone? Might still be worth trying to change the USB port and see what happens. On the FP4 this is a separate part, so the effort required should be minimal. Of course youâd have to get access to a spare part one way or another. Switching ports with another FP4 would be one option. That would also help determine if something else is broken.
Might be a contact issue. In the good old FP2 times the recommendation was always to disassemble and assemble back the phone or at least the relevant areas.
For the OTG vs. other data we would have to check which data lines are used in the connector and in its connection to the phone. That might be an indication what exactly is broken.
Btw, I think you could have continued in your original topic instead of opening a new one with your additional findings. Maybe they can be put together.
When looking a the USB C pinout I donât see any special connection which is used for OTG only and could explain why charging and OTG works but nothing else. And as far I know, OTG only means that the device will act as a host and provide power supply to the connected device but there will not be any special data lines needed for this.
Anyway, I ordered a USB plug replacement and will give it a try. However I wonder how this happens - mechanically there is not indication at all that anything is broken and the inside of the plug looks absolutely flawless under a magnification glass.
As expected: no change. Connecting a PC to USB does only charge the device and neither fastboot nor ADB work. So I can not even restore the original operating system since this requires fastboot connections to work, which is not the case. I did not expect anything else, but the money was well spent, so I can be sure my original expectation that the main module is broken is correct.
Iâll contact the support as well - but if they ask for money to replace the main module because I installed LineageOS, I wonât do this and see this as a lesson learned.
Oh my⌠and again the support asks for a proof of purchase! My device is registered for the extended warranty online - using the IMEI and serial number of the device! The same IMEI I entered when I contacted the support.
Hi,
I have the same issue. OTG works but not file transfers to computer. Also no connection to Android Auto. I had changed the USB board/plug but that did not change anything. Nor did any of the options proposed by the Fairphone support. And I have this is issue running Android 12 provided by Fairphone. They want me to send in the phone for repair except that I need a replacement first since I canât afford to be without a phone.
Thanks for your report on this. At least I know that I am not the only one with this issue and it is probably caused by some problem in the device itself and not by changing to LineageOS.
Well - about sending the device in: you donât have any alternative. Itâs the only way how they will handle that since there is no obligation for Fairphone to give you another device right away. This will only be provided if you donât purchase the device but only rent them using their subscription model. At least they promise to send a replacement within 48 hours if needed.
In my case I purchased another smartphone after I realized that replacing the USB port did not solve the problem. I expect that I will have to send the device in as well and wanted to be prepared as I also need my smartphone on a daily basis, e.g. for 2-factor-authentication, bank accounts etc. - it is a good idea to have a spare device available anyway, since things can happen.
Noting this topic is suffixed [lineageos] I am wondering if Fairphone support are clear that you are not using the the default OS as support is limited to that.
i.e. You have to have Fairphone OS [Android 12] installed to benefit from official support.
Failing that they will/may ask their physical support âworkersâ [Cordon] to wipe your phone and install A12 before they look at any software or hardware issues.
I already told the support very clearly that I did install LineageOS in the past and that I canât revert that to FairphoneOS since USB connections to the PC including fastboot donât work any longer. And since I already did a factory reset to make sure that this is not just a software issue, I am totally fine with getting the phone wiped as long as this is fixed without asking me for money for a new main module.
I contacted support, they told me to do try obvious things like using another cable, use another computer, try factory reset. Then I told the support that I already did all that and that I want to send in the device for repair.
Now I am waiting for another response by the support where to send it and what information to supply with the package.
After dealing with the UPS delivery guys (they claimed to deliver it, but never showed up even I was at home all day) I got the phone back. According to the service, the main module was replaced - so nothing I could have done my own.
So far the original problem is fixed. Iâll see how long this will last.
Just after turning the phone on it already offered me an update to software version SP2G.B.079 which claims to fix issues with the search bar in the launcher, display colors, 4G/WiFi call settings and AptX for bluetooth. Of course still on Android 12 - but better than nothing.
But now I am reluctant to install LineageOS 20 again since I canât be sure that this wonât cause the same issues after a while. Are there any known cases with LineageOS causing the USB port to malfunction?
