Plug your phone in and go through the steps (it will take a while to download another os.) If you get an error when it tries to install don't delete the app. Try downloading windows phone recovery tool and run it. I had this kind of problem with my phone a few weeks ago when it suffered a catastrophic error, although you should know you will lose all personal data when you try it on your phone. My apologies for everyone who read this post.' 'the package is not available for this phone' Where can I find the firmware for this phone? Thank you. In settings: 'data transfer and SIM' - network didn't find Icons of SIM card in the taskbar crossed out There's the same problem when there's no SIM-card in the phone: I didn't install anything, did not stitch, did not drop the phone, etc. There is no telephone connection, 'airplane mode' only exists. When I try to turn on or turn off airplane mode, there's only the frequent blinking of the icon in the notification bar. When I turn on airplane mode, the icon 'airplane mode' appears. When I try to call, the warning 'your phone is in airplane mode' appears, But 'airplane' isn't active and icon 'airplane' on the taskbar misses. Hello everyone! Help me, please! I have a phone 'Acer M330 WW_GEN1'.
