Yes and no. It only works in recovery while im in the Update from adb menu. Otherwise the phone is not detected (maybe because my laptop got never authorized on the phone). And once im the sideload menu I cannot do much via adb, e.g. it didn’t allow me to run a shell.
I just did a factory reset and retried. Still the same behaviour. So I’ll contact support if nobody has another idea I could try.
MTP was disabled, it was only mounted as SD card (I have no external SD inserted atm; neither is a SIM card inserted, but this shouldn’t be a problem, is it?)
I’m not sure if i understood your problem but i have the problem that my Computer (Linux Mint 13, adb 1.0.31) doesn’t recognize the FP2.
Georg hasn’t a connection problem. Later on he had a problem with rooting the phone. Here his post where he explains how he made it:
It also says that it can’t open /dev/block/platform/Msm_sdcc.1/by-name/misc (Permission denied)
I tried once more by uploading the downloaded file (not renamed) and got the same result.
I booted the phone in normal mode again, went to the USB Debug configs, switched OFF the “Verify apps over USB” and tried all again - same result.
By the way - I did not find any option in the configuration menu of the phone to switch on/off USB Debugging and downloaded “USBDebug” from the play store - a separate app, which shows the configuration options all nicely.
Any further wisdom, hints or dreams are welcome :). Cheers,
regarding 3. Update to ADB 1.0.32: "Since Android Lollipop 5.0, ADB 1.0.32 is needed to sideload your device."
So I might need to update sooner or later anyway, but this is not the problem now.
And as @georgmayer said he sucessfully used version 1.0.32.
regarding 5. If your device is not detected …: …you may be facing the USB3 bug. On modern computer, most of the USB ports are USB3 and there is an incompatibility between some Android devices and USB3 ports. This problem must be software related, as one of my phone is not recognized thru adb but is fully recognized thru fastboot on the same USB port ! The easiest way to solve it is damn simple : just connect a cheap, self-powered USB hub between your computer and your Android device.
MyThinkpad Yoga 12 indeed uses USB3. I attached a cheap Saitek PZ37 “MINI UFO HUB” USB HUB to it but it made no difference, the list of recognised devices is still empty.
But how/why did @georgmayer it working then? (If I understood his posts correctly he did, but maybe I misunderstood him and he only managed to sideload an apk, in that mode I can see the FP2 as well in adb )
Anyway, it might be the right time to contact support, pointing them to this thread (and ask them to forward it to the devs after the holidays). Andy as I should be packing boxes for moving as well right now, I might just step back a little and wait. Nevertheless, if there is anything I can try let me know and I’m happy to do so. I’m just a little out of ideas right now.
You’re my personal hero for today! MTP was (as said earlier) not enabled. But indeed the check box for “mount SD card” was enabled. Thus I disabled that one as well – leaving me with “having nothing checked” as you said – and now I got the access permission pop-up as well and finally can see the device via adb. So we can close this one as solved (for me).
