I have a Galaxy S2 I777 (ATT) that I have had on Cyanogen Mod ROM (which I love) for the last 6 weeks or so. Never had a problem until tonight. I was browsing a site and all of a sudden the phone froze. Nothing would work to unfreeze it. Tried everything I know and eventually took the battery out. Just in case, I replaced it with a fully charged battery.
When I tried to turn it on---nothing. I tried to boot into recovery---nothing.
Anybody have any thoughts???
Thanx in advance Rich:crying:
Have you tried getting into download mode? Once you can't get to recovery, Download mode is the next option, where you'll need to odin back to stock (I suggest UCMD8). There are several methods to get into download mode, I'll comb through a few of creepy's more recent posts to find them...

There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:
With the phone off (and not connected to the computer), and battery installed, hold all three buttons, vol- vol+ pwr continuously until the initial boot screen appears the second time.
Download mode:
1. With the phone off and connected to the computer via USB cable, and battery installed, hold all three buttons, vol- vol+ pwr.
2. With the phone off and battery installed, hold vol- and vol+ (but not pwr) while plugging in the USB cable.
3. With the phone off and battery installed, hold vol- (but not vol+ or pwr) while plugging in the USB cable.
4. Attempt each of the above three options with the battery removed from the phone. The computer will supply the power to the phone.
5. Use Android Debug Bridge (adb) which will only work if USB debugging has been already turned on in Developer Options, since you can't boot into the system to turn it on. With the battery installed and the phone connected to the pc via USB cable, use the command "adb reboot download".
6. Use a USB jig. With the battery installed insert the USB jig into the USB connector of the phone. Some have reported that this method works when no other method would work.
Thanx
I tried all of your suggestions except the USB jig. Don't have one; don't even know what one is. Unfortunately, none of them worked. But, I really appreciate your taking the time to respond

This:
1. Take out everything from your phone. SIM, Ext SD Card, Battery
2. Press BOTH Vol Buttoms
3. Plug USB on PC and on the Phone
4. Put back ONLY the battery
5. You should be in download mode
Thats the usual way, but, idk some devices go into download mode in a different way than the usual way, for example, mines. This is how i go into download mode:
1. Phone is unplugged and turned off.
2. First i press VOL DOWN ONLY and then POWER Buttom
3. Voila, im in download mode. No need to plug the USB or taking out the battery
I discovered it by accident, i was going to go into recovery, turned off the phone and accidentaly pressed vol down instead of vol up, and i was pretty in shock when i saw the download icon pop on my screen. I was lucky i guess, i was already planning on buying/making a JIGG lol. Goodluck!
thank u .... it work by pressing the up vol and plug in the usb...
I started the process to install one of the more stock gingerbread roms(Revolution Rom RC1). From cm7 I flashed the GB bootloader via odin, it finished, i then restated the phone to bring it into download mode again to install the JVH PDA. But i could not get back into download mode and still cannot. I can still use cm7 but just cannot access download mode. I have tried all of the 3 button methods and using terminal su, then reboot download, both methods just reboot the phone, anyone know how i can get to the new rom ?
Two buttons....
volume up + power
You don't like op's do you.
This method works every time for me:
1. Turn Phone Off
2.) Plug USB cable into computer (but not the phone for now)
3.) press and hold the Vol +& - button
4.) Plug in the USB cable to your phone.

This is what I generally use too but with the Gingerbread bootloaders just use Volume up.

If you don't plug in the USB cable, yes. With the quoted method though, plugging in the USB cable acts as power on so the power button does not need to be touched.
I got a XT912 with a screen that stays black(don't know why, it looks fine). What i am trying to do, is to get into the fastboot mode without seeing anything so i can flash a stock rom via pc. Whatever combinations i try i only get it to reboot(it keeps saying "droooiiiidd"). I googled alot and i can't find a solution for this.
The reason why i want to flash a new rom is because i want to try if i can fix this screen issue and because the screen is locked and i can't get past that and use the phone(via otg and hdmi out).
How do i shut the phone down only using the keys(without restarting) and how do i start from a powered down mode into fastboot(step by step guide would be helpful).
Ensure phone is completely powered off (also, fully charged). Vol down + Power (vol down first). Release power button after 3-5 seconds, and then release vol down. You are now in fastboot. Connect usb, and your computer should identify the phone.

What about selecting fastboot first? Isn't there some kind of menu i get into after doing that(at least i know there should be one)? Where i have to scroll down and select fastboot.
Holding vol up and vol down will bring you to the boot menu. Vol down is directly to fastboot mode.

Can i somehow shut it down with the keys? I don't know why, but whatever i try it keeps rebooting only.
Press and hold both vol buttons and the power button for six to ten seconds. Then release all three. That is a manual reboot. A working screen will briefly flash. If you try to boot to the main boot menu, with vol +/-, and power, AP Fastboot is the third option. Press vol down twice to highlight ap fastboot, vol up once to select it. This also takes you to AP Fastboot mode, as opposed to the vol down and power, which is direct.

Thats what i tried just now, i pressed vol+/- and power to reboot. Soon after i pressed again vol+/- and power and waited for like 10 sec, then i pressed vol - 3 times and then vol + and all he did was reboot again damn. Is my timing wrong? 3 times down is wrong i guess if i start from position 1. Just as a reminder i can't see anything.
Volume down twice to highlight AP fastboot, up once to select. Also, you want the phone to be completely off to boot into fastboot mode. There is no way to REboot into the boot menu

What i did now is open the back, disconnect the battery and connect it again, use vol down button + power button for ten sec and then plug it into the computer. Nothing happens, atleast not on the computer, the phone shows a white light in the top left corner. It stays on even if i disconnect the cable.
Holding for that long can cause a reboot. Try holding the vol down and power for like... three seconds, after reconnecting the battery. Also, are you using an OEM motorola cable? And, have you ever used RSDlite? Have you prepared for flashing with the appropriate fastboot sbf files? Once the computer recognizes the phone, you'll want to have the motorola drivers installed, RSDlite ready, and the right sbf file ready.\
EDIT
Even if you do access the fastboot menu, if the phone believes the battery is too low, it will not allow the pc and phone to connect. The screen should say:
AP Fastboot Flash Mode (S)
0A.77
eMMC Info: Size 16G
To return to normal mode- first press power key to power down
Device is LOCKED. Status code: 0
Battery OK
OK to Program
Connect USB
Data Cable
I realize that your screen isn't displaying anything, but this menu is what will restrict you from flashing if the battery is low. Instead of Battery OK, it will say Low Battery

I know how to use rsdlite, because i flashed my xt910 with it. The battery could be a problem. I have it fully charged and will try it again now, but if that doesn't work i propably need a factory cable. I think i made it into the fastboot mode in previous tries but got stuck because of the battery status.
Edit: Reconnecting the battery and getting into fastboot mode seems to work, but connecting the cable gives me the white light and nothing else works.
So your computer is still not recognizing the phone, even when it seems to be in fastboot?

Yep, no reaction from the os and nothing listed in adb devices or fastboot devices.
Assuming the battery power is adequate, the next and only solution is the proper data cable (OEM).
If the battery is low, you'll need to either use a TBH factory data cable, or the workaround of hard wiring a stripped usb cable screwed to the battery terminals on the phone. Once the phone identifies a good power source, it will allow a pc connection.

EDIT
BP SBF Flash is the fourth option down, out of seven total, I believe. If you can boot to the main boot menu, and click vol down 3 times, you'll select this option. As I recall, I was able to confirm my phone, usb cable, and pc were all communicating. My *pc identified an unknown device being connected, even with a nearly dead battery. Then I knew I just needed a power supply. I'm not sure what this option is for, but it told me what I needed to know.

Ok i will try that until i get one of these cables or adapters.
Is it possible to use adb via recovery or do i need a custom recovery for that? I am not sure if i need to unlock the bootloader via motorola( have to use fastboot for unlock), that would as far as i know reset the stock rom(if i need a custom rom).
i had my phone plugged to the charger overnight about 2 weeks back. it was charging then, however it was completely dead in the morning.
tried holding the power button, nothing on the screen
tried removing the battery (had it out for > 1hr) and then inserted the battery back and tried charging/starting , nothing on the screen
i tried the power + volumerUP + volumeDown and nothing on the screen
Tried plugging the USB to a computer and tired to put the phone in download mode , but screen was dead.
i tried replacing the battery with a new one (from ebay) and it is still dead. the battery show about 3.8V when i check the + and - terminals using a multimeter.
it was working the night before and was dead in the morning, the phone is about 22 months old and it was running the original rom (i had rooted the phone about a year back),
i am not sure if the phone is bricked, please help guys.

bricked = no sign of life under any circumstances
Try putting the phone into download mode when the battery is removed. Pull the battery and leave it out. Connect the phone to the PC via USB cable, and hold down vol+ and vol- (but not pwr). The USB cable will supply the power. Let us know if it will boot into download mode using this method.

Thanks for the reply.
I tried to put the phone in download mode when battery is removed, however there was no message/flicker either on the screen and the computer did not recognise any device. I held the vol+ and vol- buttons together for about 15 seconds.

Sounds like a true brick. The phone is getting old enough that it may not be cost effective to send it out for repair. But if you do choose to go for a repair, Mobile Tech Videos in LA has a very highly respected reputation here.
There are several ways to put the phone into download mode. You should try all of them that you can before you give up.
Recovery mode:

My phone switches off everytime I'm charging it
I have tried the power + volume down and plug the usb into the pc and I get to the Modified recovery where you can go into safe mode or factory reset, etc. I have done it before but it was Kingo root that did it. It's not working because I can't get to usb debugging mode. I need to go back to stock. Thanks

If you are using the LGUP method, you do not need to even go into download mode. If you are on the Verizon bootlooped screen you should be able to flash it back to stock right then and there.
Also there is no real recovery method that you can use so you will have to wipe it completely clean unless you have backups.
LGup says phone 'unknown' so it won't work. It worked yesterday. Not sure what happened. Tried the battery pull method but it still doesn't work.

I had the same issue with my VS990. LGUP was not seeing the phone. Using the Recovery menu via power + volume down, I booted my phone into USB debugging mode. LGUP was then able to recognize my phone. I then chose the tot file, chose upgrade instead of refurbished, and clicked start. It auto restarted my phone into Download Mode and started the upgrade. If you can get the phone into USB debugging mode, you'll be set.

Plug a USB cable into your phone with your phone powered off, hold down on the Vol Up button and plug the USB cord into your computer. It should immediately boot into download mode. I have verified this works on my Verizon V10.

Huh. I did mine from a regular boot up, but in debug mode. LGUP commanded it to reboot into DL mode for me.
Download mode on the LG V10 is achieved the same way all other recent LG smartphones have been. Power the device off completely by either the power menu or battery pull. Plug your USB cable into your computer. I didn't have an issue with USB 3.0. Hold Volume up and plug in the phone to the computer. Keep holding Volume up until the phone says download mode. It will do a small loading screen then it will change, this is normal. You can leave download mode by pulling out the battery or by holding the power button for 10-15 seconds.

I think you might be doing it wrong...
Download Mode -> Hold volume up, and plug into usb while STILL holding volume up, release once in download mode
Reset Screen -> Hold volume down + power, then plug into usb whil holding down buttons, release when screens comes on.
Ok, now for my problems. I got my phone into DM, used LGUP to install VS99026A_00_0118.kdz on my VS990. I let it go overnight. Came back to see it failed at about 73%, Error "can't get laf property", ever since then I can't get back into DM again, my LG splash screen will come up, then I get the android guy saying "Erasing...", then it reboots to splash screen again, waits a sec, then turns off. I managed to get into the reset screen with vol dn + pwr + usb method, tried to go into safe mode, now I have same issue getting back to that screen too.
Any help?
