My 12 month-old Android Jellybean will not read SIM card, has removed some apps and will not load downloaded apps into phone memory or CD card


I would recommend backing up the device and then resettings to factory defaults, sounds like your software may be corrupt.

Settings > Privacy > Storage > Factory data reset.

Sony ericsson died and wont switch on


It's likely that you need to reflash the phone software to your phone. You can do this yourself [detailed instructions and files at se-nse.net] or just do it at a phone shop or through an online site like Da Vinci or Wontan.

But something you should try is to remove the battery and take out your SIM / memory card and then let it sit for a bit before you reinsert the battery [withouth SIM / memory card] and restart the phone. Hopefully that'll work, if not then you'll probably have to reflash the phone software. But you could always check by doing a software upgrade using SEUS [Sony Ericsson Update Service offered for free here - http://www.sonyericsson.com/cws/support/...

Nokia n73 dead


Hi there, remove the battery ,memory card & sim from the phone. Then fix again battery and sim card. After that confirm, your battery is charged. Then on your phone. If its working , then you sure that, your phone is ok. Now off the phone and put the memory card back on your phone, then turn on again the phone. If that time not working then your memory card is a cause of your dead phone. If your phone dead with out using memory card, then the operating system of your phone corrupt or an internal damaged happens. In that case your must visit Nokia service center. Do not try at home for resolving the phone hardware or software problem. Because some mistake can make a loss of your phone for life time.
Thanks & waiting for your feedback.

I lost the phone and when I found it the battery was dead. After a little bit of charging the phone would only come up with a white screen that says "SGH-T339" but wont go past that.


My step son had the same issue. I removed both the SIM card and memory card from the phone before turning it back on. Once the phone got past the "SGH-T339" screen it tells you to install the SIM card. Remove the battery and install SIM card and turn phone back on. It has worked ever since.
