too DUDU-Meng I don't think it's a contact problem. It happens sporadically in the parking lot at home where there is plenty of signal.
at_cleric When the SIM card is on and Wi-Fi is turned on, the SIM card is not detected when coming out of "Sleep". The error is unstable. But when Wi-Fi is turned off, there is no such error, I have not observed it.
DUDU-Meng Chrisdudu at_cleric too Hello everyone, this is a system optimization for some SIM card issues after waking from sleep mode. Please upgrade to see if it can solve some SIM card issues. Thank you. https://drive.google.com/open?id=1sQfGxx5CTuhaBfeg0e-wpSIY8XkkjaAJ&usp=drive_fs
DUDU-Meng Chrisdudu Thank you for testing. Extract the 7Z file to a USB flash drive. The USB flash drive will be automatically recognized when inserted.
Chrisdudu DUDU-Meng I’ll try to find a place with WiFi. Can I download it on the radio, put it on a USB stick via the car and then install it? I don’t have a laptop the next few days. Also, does it reset all the settings?
DUDU-Meng Chrisdudu It will not reset the settings, but you need to extract the 7Z compressed file to a USB flash drive or internal storage so that it can automatically detect the upgrade.
DUDU-Meng Chrisdudu You cannot use this method. Here, you need to verify the MD5 of the official version. Unzip all files to the internal storage or to a USB flash drive, and they will be automatically upgraded.
Chrisdudu DUDU-Meng I finally got it to install, I will get back to you if the issue is resolved. I give it a few days and report back after the weekend.
Chrisdudu DUDU-Meng Ok some findings: after longer sleeps the unit does a fresh start. So the bootlogo comes up. Not a big deal. after short stops (10/12 now) I have no issues with the simcard. Always starts up. I do have a new issue, that is far worse. Since this update all my usb ports stopped working. So that is a major issue. I cannot do an update or connect anything.
DUDU-Meng Chrisdudu Can you tell me if the usb not working is also a problem after waking up from hibernation? Can I restart the system manually to get it back to normal?
