[Q] What does emptying cache do?

If I empty cache via Recovery Mode (with phone off: vol up + home + power, keep pressing the first 2 buttons ), what happens?
Can I do this on a fully (100% official ROM and NOT root) "finished" phone without losing anything?
Thanks

Home Button not working anymore ! DEAD ! :(

Hi guys,
i flashed my sgs with super optimised kernel 3.7 from 3.6 .... = bad news ... i realised that my home button does not work anymore so i have to use the back button instead of home button it took me many hours to figure and fix my sgs but still no home button working but at least my sgs did not turn into a paperweight.
below are the series of events that happened (i tried to put it in order as much as possible)
- home button stopped working
- alot of FC'ing
- sgs kinda like jammed or stuck
- did a full reflash from step 1 [HOWTO] Froyo FW I9000XXJPM: Upgrade via Odin, Root, Recovery 2e, Lagfix! several times !
- flashed a couple of times but when phone enters recovery mode after 1st flash i cant select wipe data/cache cos home button not working so phone was turned off and entered download mode then flashed JPM.
- also tried to flash in 3.6 version kernel couple of times to overwrite 3.7
- here are some stuff i saw along the way :
--there were occasions i see a mobile logo with arrow pointing to pc (just like the background pic of recovery menu but no menu till i unplug usb)
--after reflash when it enters recovery mode automatically it will then not show menu and android logo with a caution sign was seen but when usb cable is unplugged recovery menu comes back but still no luck to wipe data/cache cos home button not working
--instead of seeing recovery 2e , 3e was shown but then again i cant select wipe data/cache due to home button not working
i'm sure many reading this is figuring how i managed to enter recovery or download mode without the home button ???
-- just hold vol up/down + power button home button is not needed in my case !
while in recovery menu, i cant select or do anything with home button except moving vol up/down button to highlight selection but cannot "enter" with home button so i turned the phone off and continued flashing JPM and it works.
but while inside the 3.6 or 3.7 kernel, i can move up or down using vol switch and how did i manage to "enter" selection without home button ? i discovered that the power button does the "enter" !
home button was working intermittently but it comes with double click where you bring the last 6 used apps and task manger selection .. but now it does not come up anymore. still can feel the click on the home button but no response as for now.
also flashed several times as mentioned with re-partition ticked to try to wipe everything but still same results.
so now i have ended up with :
PDA : I9000XXJPM
Phone : I9000XXJPM
CSC : I9000 OXAJPM
Build info : 2010.10
Baseband : I9000XXJPM
Kernel Version : 2.6.32.9
[email protected] #19
Build Number : FROYO.XXJPM
i have also tried many ways such as formatting sd, system, basically almost every menu in the kernel ! basically i wiped out previous data (my guess) but all the apps + data are gone. it was a PITA process.
now it is just the freaking home button does not work anymore ! but nevertheless quadrant still shows 2216 ! and the phone is still blazing fast .
hope someone could help out i have tried to do the search function but not much luck related to my issue.

i have the same problem .... my home button is dead as well -.-'

Flash back to an Eclair firmware. See if that changes anything.

[Q] Coming out from DOWNLOAD MOD ?

Hi,
How can we come out and reboot the SGS from DOWNLOAD MOD screen if we do not download anything or not connecting to PC ? Meaning we remained in download mod screen and we want to reboot..
I myself can do it by only removing the battery..
Is there any other easy method w/o removing back cover and battery ?
Ths in advance for useful advice..

I don't think so
Btw why do you want to do this <
Edit : I think there is a hardware mod that does this. i am 10 % sure about this though ...

Yes you can press the Powerbutton for about 10 seconds. After doing that the phone reboots normally.. So there is no need to pull out the battery

since u're using a custom rom suppose it's comes wif safe kernel
so u just need to enter to recovery n do a backup of ur data.
after backup u can just do a factory reset hopefully this helps

You have not provided enough information.

Pull out the battery and let it stay for 30 sec. Put it again and plug it to the charger. Let it charge for around 2 or 3 hours. Try to power on it. If not, press Home + power + volume up, and then wipe data. If you cant go to recovery (so strange) pull out the battery, put it again and press home + power + volume down for 5 seconds and then volume up, (dont worry if the screen doesn't turn on. Then flash a stock rom with odin.
But, we need more info, what you did before the problem appears?
Rom?
Kernel?
And please, what class of english is your one? I know im bad on english but not at THAT way. Good luck
