    the phone dropped into water last night, but I immediately grabbed it and disassembled it. It appeared to work fine after that point. As mentioned, the battery died last night and I fell asleep with it uncharged. I've tried to use your suggestions, but nothing appears to change, the "emergency download" screen remains. Is there anything else you can suggest? Thank you for the help!

Just remove sim card and start phone without it then put sim card back in and it should work fine, and if that fails to correct it or you are on Verizon with no sim card, download the firmware update here
Just follow the instructions on the site.
There is one other risky temporary fix (which can damage the phone but has worked). It may fry the circuit board but others have done it with no problems, put your SIM card back in the VU, take the battery out of the phone and plug the phone into the charger, now when it comes up with the screen saying insert battery put it in, then wait for it to come to the charging screen then hold down the power button to turn it on.
Everytime your phone goes off you have to do that, but in a worst case scenario you can get the phone to work until you can get help from a service provider. Just power down the phone and turn back on before walking in so the error comes back. I have no landline in my home so having a "working" cell phone is mandatory for me, even temporarily.
I hope this helps and good luck!

    Well, that changes things drastically. You failed to mention that you dropped it in water. Take out the battery, sim card, and memory card (if there) and stick the phone in a ziplock bag filled with uncooked white rice. There is moisture/water in the phone still. The raw rice will absorb any moisture in the bag (the phone) drawing it out of the phone. It acts like the little bags you see inside of electronics boxes (silica gel). If you have any of those around you can throw them in with the rice as well. Give it at least 24 hrs. Do not open the bag for 24 hours, don't check after 12 hrs etc., let the rice do it's job.

LG Thrive Charging Issue


It's possible that your battery has gone bad. The first thing I'd do is a factory reset (I know this means you'll lose all your data, but the phone store is going to do the same thing anyway as part of their troubleshooting process). Then, after resetting the phone, see if it charges.

If not, take it to your nearest service provider's location and ask them to troubleshoot it (if you have a protection plan or warranty).

Otherwise, I'd start by replacing the battery (you can get them online or from your phone store). From what you've described, it sounds like the battery or POSSIBLY the charging port. It's not uncommon for smart phones to have their batteries suddenly die on them. I've had several LGs and a Samsung that have done this to me. Out of the blue, they will just quit charging and every time it's been a bad battery. Replaced the battery and the issue went away! That's the cheapest place to start, anyway.

Good luck!

Hi i bought a nokia n97 almost a month ago,and one time i went to bed and left it to charge and woke up with the charger not working. ive been told its an electrical problem so i changed the charger,now...


In the manual with my Nokia 5230 Nokia says that when the indicator gives a sign about the unit being fully charged one is supposed first to take charger connected to the phone first and then the plug from the electricity. Take another look at the manual of your phone and checkonthe information on charging

It won't turn on. It worked last night and I plugged it in before I went to bed, and when I woke up it was black. It won't turn on now or make any type of sound.


battery could be gone..also you could check wire connections to battery. Even better measure if the battery has a charge with a voltmeter.

Phone doesn't turn on.


You should not allow the battery to fully drain,it will die sooner.

Remove the battery for 5mins, replace,and then try and turn on the phone.

The battery might not just hold any charge. If you have had this phone for less than a year. I would try to get a replacement from the carrier.

My phone battery died, and I plugged it into the charger over night, and when I woke up in the morning it didn't charge it any. I tried a different outlet, and it still didn't charge.


actually the batteries should not be over charged..

once the charge is full you should stop charging it more..
it you leave it over-night the battery will lose its back-up

you should try a new battery..

Archos 404 not charging


Dont use the USB to charge the 404. Use a wall charger that accepts USB. Wally world (Walmart) has one for 15 dollars that has 2 USB ports. It works for me. Also the docking station will charge the 404 in no time at all. It's 80 dollars. Make sure you get the generation 4 unit
