I tried unrooting my phone, but it got stuck in a boot loop.
When I try to enter to recovery mode to factory reset I get an android lying on its back with a red triangle.
I've tried a bunch of combinations of buttons, but the phone just turns off if I hold power + volume up.
In cmd prompt on the PC type: adb reboot recovery. That should work.

that is the stock recovery. what you want to do is flash the factory img via the bootloader/fastboot.
You have the buttons right, but you don't really hold the two down. It's a bit tricky but once you figure out the exact way to do it, it's easy.
Press and hold the power button then immediately after press volume up. Then let go. The menu will appear.

Your device should be called Nexus 4 and not Samsung. Install the drivers from here http://forum.xda-developers.com/showthread.php?t=1996051, after that connect the phone through usb, look in device manager and delete the device. Reconnect again and choose manualy wich drivers to install and choose the driver you just installed. Now your device is called Nexus 4.
your stock recovery over wrote your custom recovery and that made the little android with the triangle come up. all you have to do is reflash a custom recovery using fastboot.
go to zedomax channel at www.nexus4root.com and he gives you video instructions using the cmd on your computer
Try this:
Go into bootloader and recovery
You will see the android with the red triangle
hold power and press volume up (tricky part)
wipe cache
If this doesnt work try doing a factory reset instead

I have rooted using the rooting toolkit.
Great toolkit by the way.
That gave me a cwm.
I installed ROM manager n choose the cwm touch.
Now I have a nice touch version cwm.
But I can only enter it via ROM toolbox or ROM manager in app option
The power + volume own combo doesn't work anymore.
Naturally I googled n search about this.
Is a common issue and the solution is usually this 2
Use adb, I have no idea how.
Plug a USB cable.
I love the USB cable idea but I don't get how it works.
There is no description on it.
I plug my USB cable, and try the combo,
I got into boot menu, I navigate to recovery, and it got stuck there
What should I do?
I'm worry to flash anything fearing I can't get back to recovery if my tab don't boot.
Well one way to get abound it is any CM10 Rom. You old the power button, click rebppt then select reboot recovery to reboot into it. It kinda is a problem if you don't want to flash anything though.........

dumb questions: did you plug it into computer? does adb work when you do so? If these two are true, I imagine the three button method should work when plugged in.
(But I'm just speculating, really.)
If adb does work, then worst case scenario you should be able to "adb reboot bootloader".

Thanks for the USB Trick
I manage to get it to work already.
Just plug the USB cable to the tablet, and connect it to a computer.
Then use the power and volume down combo to boot into cwm recovery.
Previously I tried the combo only with the USB cable, but not plugged to a computer.
why we need to plug in a pc???, my phone doesnt need....
just power + volume down!

How do you do it?
If I use that key combo,
It will lead me to a menu, I use volume button to select recovery,
The tab will then just stuck at the Google logo and never enter cwm.
It is a bug in the bootloader... many threads about it.
Simple fix use quickboot app. Press a button and you're in recovery. No keyboard needed.

I just went into Fastboot, Power, both volume keys then scrolled to recovery... worked like a charm... dunno why it wouldnt.
Unless set by CWM, Nexus 7 will automatically try to restore the stock recovery that's why you are stuck. Once in CWM recovery, there should be an option to block android from doing so.

It is really easy to get into Clockworkmod Recovery. Install Rom Manager vv5.0.2.1 from the market and Flash ClockworkMod Recovery. It should list recovery 6.0.1.0. Then choose Reboot into Recovery from Rom Manager. Done. Now you have the full CWM recovery with access to all the things you don't have in stock recovery.

long pressing(10-20 seconds) the power button will reboot the device. if you also press and hold the volume down button when it reboots, it'll take you into the bootloader. from the bootloader, press the recovery option.

I tried connecting the device to my computer via USB before selecting recovery. When I do that, volume up/down and power do nothing! So I have to reboot by holding power again. What do you think now?
I didn't realize I had to update the bootloader I was in the process of updating my ROM from SmoothROM 4.1.2 to Modaco 4.2 and it did not flash properly. So at this point, I cannot boot up. I'm stuck here.

Someone please comment with help! My phone was rooted and I flashed TWRP and saved a restore rom of "Stock Root". My phone must have gotten warm and now it only boots into TWRP. I have tried flashing my recovery (Doesn't work), using ADB Sideloader (Never Finishes running), Using Terminal Command (how do I navigate to Start Folder?), and using ADB commands to push file. The big problem I am seeing is my computer is saying that drivers aren't installed. I re-install the drivers I used when I rooted but still nothing. I run adb devices and it is not listed. I just want to get back to my stock root or be able to flash a CM stable. Please help!
I have been all over this site and it is always helpful but this time my searches have not led to sucsess...

When you hold these two buttons and you see the LG logo, release and hold them again fast until you see factory reset screen. At this point press the power key three times and you will go to recovery. An press the thanks button here.

I think you have have to hold for 5 seconds to completely power down.
Hold vol- and power key and when logo pops up release power key and again hold power key then Reset screen should display. Press power until it starts factory reset which will dump you into Recovery.

Hey guys,
So my Verizon G2 was on the stock rom with root. I wanted to install TWRP on it and flash a rom but couldn't get to that due to the fact that I couldn't get TWRP running after I tried flashing it with Flashify(I did this after having the first OTA). Another OTA came up today and I legit accidentally hit install now. I'm currently stuck at fastboot and I can't even get into download mode or anything. Hard factory reset doesn't work either, I just get :
[2950] Fastboot mode started
[2970] udc_start()
and nothing happens. I really hope I didn't brick my phone.. Please help!
Thank you!
I was given a G2 that was bricked, all it would do is sit on the LG screen forever. I followed this guide: http://forum.xda-developers.com/showthread.php?t=2448960 and put the factory firmware on the phone. I never took any of the OTA's cause the phone wouldn't even boot up, but I would think its close to the same situation. The guide posted above worked for me

Damnit-- I am in the same boat. Vol down or up when plugging in does nothing-- just a glowing black screen after the LG logo. Device manager is only seeing it as a qhusb_bulk device even though the lg drivers are installed. None of the tools recognize it at this point. Almost ready to give up and call it bricked.
Did you make sure the phone is completely off? If you hold power and volume down buttons, it will shut off. Once its completely off you hold the volume down and continue to hold it while your plugging in the USB. I believe the drivers have to be installed as well.

If you follow them exactly as stated, it will flash you to 100% out of the box stock, you WILL lose root and SD storage FYI.

I was able to finally get TWRP onto my phone last night, so I'm no longer stuck at fastboot. However, I'm not just stuck at recovery. Even after flashing a custom rom, I keep getting sent back to recovery. I did notice however, if I go to backup, the data partition is at 0mb, despite formatting data and cache already. I tried the dd commands in the link above with adb, and I get nothing(file doesn't exist). I'm at a loss. What can I do now?

I know it took me all night...im kinda noobie...
Ok bear with me...use the second option from thecubes link, when in TWRP, go into terminal command, it will open a bunch of file options...ignore those and hit select on bottom right. That will start the command which will give you two sets of 6 figure numbers beginning with 6 and an out of memory error. Again ignore....hit back arrow till back to main screen and try what i said before. Again I am kinda a noob, so if my directions are confusing be patient and i will try to help.
