What is default language on your phone? If you switch your phone to English and click on first item, follow system setting, will it work?

Reported to software team.



Yeah, that would be nice. For now only thing I can do is send them report of your findings.
I sure hope they treat this with urgency.
Right now UP2 is totally unusable - half the time it doesn't power up, and since I use UP2 outside, I don't have charger/cable to jumpstart it.
It's a worthless brick at the moment - that I paid 70$ for...
So I have to use FIIO devices (BTR3K/BTR5) instead - they don't brick their own products.

Is it possible to roll back to the previous firmware?

Yes, you can freely roll back to older firmware.

Here is link to older UP2 firmware:

I have reverted back to 1.7.5:

Unfortunately, it didn't fix some of the problems.

Car mode remained enabled (wasn't it disabled in 1.7.5?), and it still functions incorrectly.
UP2 still sometimes fails to connect automatically after powering up.

@Shanling - please remove v1.7.8 from your website, so people don't keep bricking their devices.

There is no car mode in V1.7.5. And sent you PM to look into more details.

You are so far only person reporting such issue with UA2 powering on.

I have my UP4 updated to 1.3.2 via the Shanling Control app, now when it is charging it is automatically turned on.
No matter how many times I turn it off while charging it automatically turns on, made aware of it by it keeps getting connected to my phone/pc.

Is there a setting that I need to change or is this a software bug?

Please make sure that vehicle mode is turned off in Eddict Player app.

Looks like v1.7.5 firmware doesn't overwrite all they bits changed by 1.7.8, so car mode is still alive.
Although its functionality has changed a bit from what I wrote in https://www.head-fi.org/threads/sha...low-latency-aptx-and-aac.892316/post-16612350 :

When turned off, and connecting USB cable - "Power ON" prompt once, blue and red blinking light, doesn't connect automatically.
When disconnecting the USB cable - no prompt, doesn't power off.
I have to power down and power up UP2 to get it connected to the phone automatically.

UP2, not UA2.
Could be related to the revision of the device - mine is the first revision, one that doesn't support OTA.

Had this with 1.7.8, but went back and dont have the problem. Went back straight to 1.7.3 though, didnt try 1.7.5 after downgrading.

Also first revision

When i connect phone <-> shanling up4, it starts charging my phone, i don't want up4 to lose battery charge, is this hardware feature? or can it be stopped via firmware?

Also, Up4 in USB Mode after firmware update 1.3.2: says power on/pairing, power on/pairing, every 2-3-5-10-20 minutes, very stange glitch, basically stops any music i play on my PC, then i have to wait a little bit, and then again, press play music to continue

UP4 charging the phone? That shouldn't be even possible. I would say that's definitely some issue on your phone, which is not correctly recognizing UP4 as a simple DAC/Headphone dongle.

Can you please try to turn on and off vehicle mode in the app? Might be some strange contact in your USB, that would be causing it.
