the other method is to reboot and keep hitting the vol- . not hold.

Just do same steps but with battery in.
Sent from my LG-P880 using XDA Premium 4 mobile app

no result
thanx for all , but i tried the two solutions but no result , it always starts on LG logo and sometimes on LG Recovery

Turn phone on,connect USB cable, hold power button and vol- until the screen flashes to turn off, RELEASE POWER BUTTON BUT KEEP HOLDING VOL- , if the phone vibrates you held power button too long, you can also select reboot from power menu and then start holding vol- without using power button

Just to make sure: the other end of the cable is connected to a computer? (Sorry if this is a stupid question but you never know:sly

[Q] Download/Recovery mode not working !! Help !! :(

My phone is not going in either of the download / recovery mode. I tried many times. Both 'Vol up + home + power' and 'Vol down + home + power'. But the phone runs in infinite boot loop until i release the power button, after which it starts normally.
May be i should try this . But as per what i found in google search is that the 3 button issue was only in 2.1(Eclair). And mine is already on 2.2 (Froyo) which i updated officially through kies. So has it been disabled intentionally or the bootloader is buggy version which i need to update using this guide ??
try to hold the power button for 4 seconds exactly. Release it just when the logo screen disappears. Sometimes if I hold it too long, it doesn;t work.
Also, if your phone is working, try an app like QuickBoot that will take you into those modes automatically.
For some people have problems getting in to download mode, try volume down home and power it worked for me.
Download mode is Volume down not up .

I tried it, its not working. I release the power button exactly when the boot logo disappears. Then the phone boots again (boot logo is displayed again) and phone starts normally.
Also app like QuickBoot is not much helpful as i'm thinking of flashing through ODIN and i need both the modes working before starting the flash procedure !!

Yeah i have tried factory reset. And i dont want to use the USB jig just now. USB jig is for emergency i suppose and u can only go into download mode and not recovery mode. I want download mode and recovery mode running normally. My question is that, i it possible that these two modes are disabled as mine is 3 UK branded phone ?? Should I try this ??

Can you enter recovery? If not this is probably the same thing what happened to me.

Remove the battery for a few seconds and plug it in, then do this.
Push the volume up + home button + power (start with volume to home to power, keep holding all, dont let go) until it boots.
when i do that it just reboots and coems back to the same screen
but when i use the volume down and home and power i get to this thing called download and then i see "odin" then says downlaoding and now not turn off your target and i can my laptop being connected to the phone.but then thaats all

Good, apparently you are a major noob ( ), do read some guides before doing anything from now on.

where the hell is my fastboot mode ?!

On the road to root my new razr i, I'm stuck at the very first step, i just can't access the fastboot mode
So, phone off -> push volume down and power simultaneously ; my phone just boot in normal mode... Tried some variations, released buttons at different stages, and failed miserably each time.
What sorcery is this ? Am I a wizard ?

Hey guys,
I want to get my Mi 9 Lite into EDL mode - MUST this be done via hardware pins ? Or is there a way to do it without opening the phone? Some say press all three buttons and wait for a black screen but I dont get black screen only a restart
Magisk?
Magisk has Reboot to EDL option thouth I've never tried it.
When the phone is off, press both vol+ and vol- and then power.
