[Q] What does emptying cache do? - Galaxy S I9000 Q&A, Help & Troubleshooting

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

launcher error bootloop

Hello!
i have an sgs that every time it powered on it goes on an error bootloop of the launcher, and when i choose force close it goes on and on...
the second problem is that the 3 keys combo for entering download mode doesnt work, i mean it just power the phone...
the third problem is that adb cant find the phone after drivers installed.
what options do i have?
sorry for bad english...
Try doing a factory reset, wipe cache and Dalvik cache...and reformat Internal SD card (first remove any importants stuff like pictures)
i cant acess anything in the phone the error deny it from me
Not even recovery mode? Power down phone. Pull battery. Put back battery. Hold down volume up + home key + power button. If this doesnt work and you cant enter download mode with 3 button combo...looks like youll be making a jig. a 302k resistor jumped across pins 4 and 5 of the micro usb. I made one before for a buddies phone and it saved him.
Hold vol_up button, power button and home button for a few secs, when the samsung logo comes up, let go; in recovery mode go into advanced - fix permissions, then after its done, go into advanced again - Wipe Dalvik Cache.
no recovery mode, the phone is unrooted and without recovery
there is really no solution?

[Q] Bricked Note

I think I bricked my note. After turning it on, it pop up the " Samsung" animation and the screen went totally blacked. When I hold the Volume Down + Home + Power button, It went into the downloading screen in Odin Mode and it got stucked there. Can anyone help on this ? thanx in advance.
If you put into download mode then it has to stay there in downloading mode, it stucked in downloading mode means? what process you have performed after entering in download mode?
go to recovery , Home + Vol up + power
wipe cache, n wipe data if needed (u will lose data)
thanx dr. I managed to get it done. i download the stock roms

Do you have ADB? If so you can use a terminal window with your phone connected to your computer via usb and run a command to reboot into recovery.
One way to get to recovery is to hold the volume keys while plugging into an ac charger. Once the charging screen fully loads, you should be in recovery. Also, certain kernels don't require the power button to select in recovery; try pressing the softkeys.

Your power button is broken right? Does the power automatically turn on if you insert the battery? If yes, hold both volume buttons (+,-) and insert the battery. That works for me, I have a broken power button too.
I factory reset it via phone privacy menu and I am no longer getting the inconsistant message. And phone is rooted and everything works great.

[Q] Startup Problem

My Motorola Atrix Hd won't boot up every time I turn the phone on the m logo shows up then goes to the recovery screen that have a red triangle their and stay their for a wild then goes back to the m logo how do i fix the problem
If it keeps going to recovery, you could try wiping cache and Dalvik to see of that happens. If this doesn't help, you may need to wipe the data partition too. If that doesn't help, you may have to re-flash the stock ROM.

how do i wipe the data partition
When you boot your phone, it goes right to the dead android all the time? If it does, that is recovery mode. I think you press the volume up key, select the option to wipe data, and reboot.
Special boot modes
Recovery: Hold Volume Down & Power simultaneously.
Bootloader: Hold Volume Up Volume Down & Power simultaneously. On the next screen use Volume Down to scroll to bootloader and then use Volume Up to select.
Fastboot: Hold Volume Up Volume Down & Power simultaneously. On the next screen use Volume Down to scroll to bootloader and then use Volume Up to select.

i did that but the phone is still doing the same thing
What ROM was your phone running? Does it have an unlocked bootloader? Did this happen after you did something to the ROM?
I am also have startup problems.
I manually restarted my phone and it fell into a black screen. No logo motorola. I made ​​all [power + volume (+, -)] => My phone booted into normal.
The cause of this problem?
Since I have a problem I did not start that way anymore: Power -> Reboot
Instead I just power off.

Try flashing a rom using rsd lite.
