Use this method to hard reset your Samsung Galaxy Pocket S5300 phone: Enter *2767*3855# , or use volume up + power + home and wipe data
good luck

Are you sure the volume is all the way off? If so do a hard reset and then try again

1. With the Samsung Galaxy TAB turned off, press and hold the VOLUME Down button, and then briefly press the POWER button.

Note: If you see "Downloading" on the screen with an Android shoveling you pressed the wrong Volume key. Remove and reinsert the battery and try again.



It should hard reset any of these tablets:
Reset GT-P6210 Galaxy Tab Plus 7.0 WIFI
Reset GT-P6200 Galaxy Tab Plus 7.0 WIFI + 3G
Reset GT-P6810 Galaxy Tab 7.7 WIFI
Reset GT-P6800 Galaxy Tab 7.7 WIFI + 3G
Reset GT-P7310 Galaxy Tab 8.9 WIFI
Reset GT-P7300 Galaxy Tab 8.9 WIFI + 3G
Reset GT-P7510 Galaxy Tab 10.1 WIFI
Reset GT-P7500 Galaxy Tab 10.1 WIFI + 3G

you must do a hard reset of your device,

Good luck.

My son and I both have the first galaxy S phones, love them. Yesterday his went black, just the 4 buttons on bottom lit up and it would vibrate. No one was able to help us so we bought a prepaid phone as a temp fix. I tried everything even the holding of the volume and power button to hard factory reset..would NEVER get to right selection before it went wonky.

Well this morning I thought that something might be up with the power on button....so I:
1. removed the back and the battery from the unit.
2.very carefully removed the 7 screws.
3. VERY GENTLY pried the screen from the back.
4. Very gently opened up and used a can of air to flush out the pocket fuzzies. the front nevery did come completely off, just the side with the power button.
5. the power button fell out/off and I gently replaced everything.
6.replaced the battery and did a hard reset.
7. Works perfectly now.

Funny thing though, last night while my son's phone was acting up, so was mine, and I had to do a hard factory reset on mine also. It was vibrating at strange times, and would either freeze of get loggy between screens. Fortunately I backed up all of my contacts with my email account.

BTW I am a 49 year old mom, if I can do this anyone can.
