Re: offline mode

Offline mode is an indicator of water damage or moisture damage. This is considered physical damage to the phone, and one would have to pay the deductible if you had insurance in order to get a replacement. If you don't have insurance, check for upgrade eligibility.

Re: offline mode

I have a samsung too and it is doing the exact thing. I washed it and it is in offline mode and satellite does keep spinning. I sure hope someone has an idea. I have no insurance.

Re: offline mode

The “Offline Mode” message can be the result of a sticky keypad, there may be one or more keys stuck in a down position. However, this error message usual indicates the E-boot sector has sustained corruption. This is normally the direct result of liquid damage. Such liquid damage inflicted upon the handset will render it useless and it not recoverable. In rare circumstances, the Emergency Downloading message can be corrected by performing an E-boot sector flash via a Product Service Tool (PST) or by replacing the malfunctioning component(s) through a repair process if not affected by liquid.

Offline mode means that your phone aint getting any signal from your mobile service provider's BTS. You need to check it from your mobile service provider if there's an ongoing outage, you need to check as well if the sim card is properly inserted. Try powercycling your phone.
1. Turn off your device.
2. Remove the sim, memory card and battery.
3. Wait for at least 2minutes.
4. Plug back the SIM card, memory card and battery.
5. Turn on mobile phone.
6. Check if you are still getting offline mode.
7. If so, try to insert your SIM card to a different phone.
8. If using a different phone for your SIM displays offline mode still,then its your SIM card which is faulty. If it works fine make sure that you inserted the sim properly or the SIM card slot might be faulty.

No reception on cell phone "No Network Service"

You need to check the RF. The RF is a component that pick up the signal. It is usually placed on the upper portion of the phone where there's a small exhaust so that the RF could pick up the signal better.

Once the RF gets wet, the component might become defective.

You need a phone tech to check or change the RF.

Have a great day!

Flash stuck on LG VX6100

If it survived one dunking it will most liklet survive a second SOOOOO. I am into R/C stuff and when our gear gets dunked we rinse it out with ultra pure water, Deionised/distilled water if you can get it. I think that the detergent in the washing machine may have left a residue and be affecting your electronics so if you wash it carefully in distilled water (yep dunk it again, crack it open and wash it all inside)to get rid of the detergent residue on the board (note REMOVE BATTERY). Afterwards dunk it in methylated spirits (test to make sure it wont affect any plastic parts first)to remove the water and leave to dry in a warm spot for a day at least. 2 years ago I dropped a $500 transmitter in a dirty dam (Acid /fuel/road runoff)and did exactly this and its been fine ever since. Worked the next day in fact. Its not a mobile phone but its always worth a chance. Once you've finished you may want to take it apart after you've tested it if its going and spray the board with CRC 226 circuit cleaner and water repeller. I've got it on all of my R/C gear and it gets regularly soaked for up to 1hr at a time in muddy water and is all fine.
