How to hard reset KU3700 when stuck at "udc_start()" - Optimus One, P500, V Q&A, Help & Troubleshooting

I'm trying to hard reset Korean KU3700. I've pressed Home+Volume Up and holding them pressed Power button.
Each time I try this I got stuck with screen displaying:
Fastboot mode started
udc_start()
And that's it. No other menu option for resetting. Phone itself is fully switching on without any problem, but as far as the screen is locked with a forgotten password I want to hard reset it without installing another firmware.

Take battery out. Hold power+ down+home. It should reset if you are on stock rom

Seems like it is not stock Rom.
Actually, that message appears and stuck when those key combinations are pressed.

Recovery troubles

I'm trying to root my phone and every time the phone hangs at the hboot screen. So today I manually entered recovery pressing vol down and power. I wanted to do a factory reset and try rooting again since I already have the OTA installed. Once in recovery I cannot navigate with the volume buttons. I have to remove the battery to even restart the phone. Am I doing something wrong or is there a problem with the phone?
are you mixing up cwm with the bootloader?

I have yet to get the phone rooted, so its not cwm. Am I not able to do a factory reset with the bootloader or whatever it is I get into holding volume down and power?
@OP:
When u come to HBOOT menu, give it ~20-30 seconds to be responsive. Then Press power button once or twice, and it should start responding.

Pressing the voldown and power button doesnt take you to recovery, thats hbooot, and why dont you just do a factory reset from the settings?

[Q] Soft Brick

Hey guys I'm going to be very forward with this. I am new to android and I seem to have soft bricked my lg O3D. Last thing I did was put the clockwork mod on and now it is stuck on the lg logo, I can get to the recovery but it does nothing. I've been searching for hours on how to fix it but always find a problem. I have no idea what I'm doing any advice would be appreciated.
Try hard reset. But you will loose all you data!!! Before you do that, take your SD and SIM card out.
1. Turn the power off. If your LG Optimus 3D is frozen, pull the battery out and reinsert it
2. Hold the Home and Volume Down button
3. Press and hold the Power button until the device turns on
4. Follow the on-screen instructions to reset your device
Thank you for the reply, but I cant because the clockworkmod is on there that wasn't meant for my phone so I need to somehow put the default recovery on.
Hello. I flashed Cm7 rom, but forgot to wipe data and now I'm at bootloop. I can't enter recovery with vol down + home +power. Any suggestions?

try just with vol down and power button, when the LG screen appears don't push anymore. you don't need to push tap the home button

Try hard factory reset. Long press power to turn it off. Hold volume down and power to get hard factory reset text screen. Press power twice to confirm.
If that doesn't work you might have a bad flash, but I'm not sure what you did.

[Q] Iconia A500 not booting

Hi, I have an Acer Iconia A500 Tab, I did a factory reset, and unfortunately I hit the reset button twice which froze the tablet. I held the power button to shut it down, and now it won't boot. The power button lights up, but I get no vibration or any visual. I'm assuming that it is hard bricked, but I'm not sure. Does anyone have an idea of what I could do to get it back. (I don't have the SBK).
Thanks

What type of rom were you using? Stock or Custom? Android version? What happens when you try to go into recovery mode? What happens when it is completely shut down and then powered back on after 20-30 min?

It was stock ICS version. I'm unable to get the recovery mode, and nothing happens when I leave the power on.

Nexus 5 D820 Bricked

Hi all,
My Nexus 5was running stock Android M till last week and I wanted Android N. So I rooted my phone installed TWRp and loaded android N by @santhosh. Everything went well but at times some apps kept crashing including TWRP. So I decided to to do a clean wipe. I did a clean wipe from recovery but after that my phone is not booting up. It's stuck on bootloop.
I am not able to boot into recovery mode also is there any way to save my phone?
Pardon my English.
Are you able to access the bootloader (hold power button + vol down until the phone boots)
I suggest using NRT to flash a stock ROM.

No i can't. It will go to bootloader When I press volume down + power but only for a second or so.. After that it'll bootloop.

Sounds like a dead power button?
Not sure, never had this problem.
But that is a common issue
The fact that the phone is not detected by the phone makes it difficult to re-flash a stock ROM.
If it is a power button issue, I recommend removing the motherboard, cleaning around the power button with pure isopropyl alcohol., quickly press and release the power button using a bit more pressure that usual, replace the motherboard, and try again.
