You probably created a shot on the board when it got wet. If that is the case, your only choice would be a new phone.

Dropped phone (Samsung SPH-M540), may have gotten wet. Screen will only show Download Mode --Mode: Emergency Port: USB


Try & press the reset button. It is near or under the battery. You night need to use the end of a paperclip. If that fails see your provider.

It could be it got too wet. Often times the blow-drier only makes the humidity inside stronger. How you solve this is you disassemble the whole phone and leave it in rice over night for about 8 hours. COMPLETELY submerged. This sucks all of the moisture out and does not hard the phone with radiation like a blow-drier. Good luck.

On my lg vu, when I unplug the phone or turn it off then back on, it says emergency download. When I manage to plug it into the charger and turn it on its fully functional, but when I unplug it it turns...


I had the same problem when mines got wet, it went away for a couple weeks and then the touchscreen stopped responding. I have ATT and if the little indicator dot behing the battery is anything but white, then your phone is done - they'll try to sell u a new one. I ended up replacing my lcd screen for about $30 and it took me around 20 mins. Mine has been going strong since then. Guides can be found on line (www.lg-vu.com) I think and you can buy the screen on Ebay or online store. I would rate the difficulty to be around an 8 for non techies and around a 1.5 for PC experienced folks.

My samsung blue flip cell phone, everytime I press 369 or#....


If you notice the 3,6,9, and # are all on the same column. There is probably some corrosion under the keypad from a spill or moisture. If cleaning the membrane switches won't work try replacing the keypad (the electronic portion, not the rubber). Repost if you need instructions. I can put some parts up on ebay for you too.

I turn on my phone it goes to a screen saying Emergency Download


Wait does it say emergency mode only? If so this has happened to me many times on this phone.

Turn off the phone and remove the battery. In there will be you should see the SIM card. Pull out the SIM and put it back in. Put back the battery and turn on your phone.

For some reason on these phones the SIM card gets dislodged. When it does the phone won't work because the SIM card is what makes the phone your number etc. All cell phones, that have no service otherwise will be able to call 911. Apparently it is a law, so that is why your phone is on emergency mode. Without the SIM card the phone is a phone without service and will therefore only work in emergency mode.

I hope this is what you meant.

Emergency Download


you can take the battery and the back off the device and place in completely submerged in a bag of white rice and leave it in there for 1 to 2 days this will help absorb the moisture, this should fix it if the water did not damage the circut boards if the water damaged the circut boards then the device is fried
