I can't switch my Nokia n810 tablet on

reprogram

If you can get the tablet apart you probably just need to re-solder the jack on.

Try "Firefox" Mobile, sounds like browser/sync issues.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/keith_f374b1cfd1696a17

What model is your S2 Tab and what is the Android version? Thanks.

Your iPad is not a glass product, who tell you that it could be cleaned by using glass cleaner? You'd better to contact Apple for help, Good luck.

Hi,

I've experienced this problem for countable times. This is not a problem with your tablet pc but a problem with the network on some sim cards (specially if it is old). You just need to wait for it until it allows you to send messages again. If this will happen for more days, I suggest you to buy a new sim card.

Hope this helps.

Isnt your battery drain ?
Have the same behaviour on mine ... I can reflash the system with supply on , but it wont stay long before reboot ..

have you tried the soft reset yet?
take out the battery and let stand in freezer (put in plastic bag to keep out moisture) for 10 mins.
hold down the switch key wich is right above the escape key on the left side of the screen. and hold down the power button till she turns on. once you get the usb symbol in the upper right turn it back off and it should run like normal.

I had the same problem with the n810. I was using a non-oem battery and the connections were a loose fit causing the battery not able to charge.
If you take the battery cover off, hold the battery firmly in place. Connect the charger and make sure battery is charging, then press the boot button. If it boots and stays on, then shuts off when you stop holding the battery. Then you probably have a loose connection or a bad battery. Also try cleaning the connector with a pencil eraser and alcohol.
I had to wedge tthe battery in place. You can find a spare battery with a desktop charger on Ebay for around $10US.
