Hi Everyone! I'm pretty new to Android stuff in general, and it looks like I soft-bricked my phone while trying to install a custom kernel.
Currently, my phone is running the latest beta of PA (pa_m8-4.6-BETA1-20140902).
I was trying to install custom kernel franco.kernel. Quick googling told me this is possible and the process was to boot into recovery (I'm using TWRP), make a backup, clear cache and dalvik cache, reboot into bootloader and then use fastboot to flash the new boot.img. Was this process correct, or was I already destined for failure?
After doing that whole process, the phone no longer boots properly. When powering on the phone, I see the initial HTC screen popup, and then the screen goes black. This stays this way forever unless I hold power + vol up, which will just restart the phone and the same thing happens. No other keys or key combinations do anything. Holding power or power + vol down does nothing. Holding power + both volume is the same as holding power + vol up. I have also tried holding the power button while holding the phone under a bright light; this has had no effect.
Unfortunately, I can't take a video of this behavior, however it appears this youtube video shows the same behavior:
CPCVecKSPAA (sorry can't post links because I'm new)
The only differences between my behavior and the youtube video are:
1. I am using AT&T instead of international version
2. At the initial screen, I see the red warning text.
Currently, my plan is to wait for the battery to die and then plug it in and try to boot into recovery with power + vol down. Does anyone know anything else worth trying?
Thanks !
Just refresh the rom... That will restore the PA kernel.
I was able to get my phone into bootloader via the following:
1. Plug phone into PC.
2. Press power + vol up + vol down.
3. As soon as charge LED turns off, release vol up.
Once I was in bootloader, I got my phone working by going into recovery and then restoring my backup.

I upgraded from 2.51.1 to 3.4.2-117, and the phone lags, seems to me that it is because of the google sync. Someone posted the very same problem and said that factory reset solved his problem.
My problem is that the phone does not do factory reset, in Privacy I press the erase button and nothing happens.
I tried to boot into recovery, but I can't get into it. The droid comes up but upon touching the lower right corner nothing happens.
When i try to boot with vol up and down same time, the phone boots into safe mode.
How shall I get into recovery so I could do a wipe? The phone is basically unuseable now because of the lags and freezes
Hey mate! Don't give up. When you see the droid in the center of the lcd just push vol+ and vol- at once. You'll get into recovery mode. )))
thx dude, i figured it out "accidentaly"
Everyone was writing on the net that the recovery boot is up and down the same time instead of the old method of power & volume -.
So, when I got to the droid, started to push every possible button in every possible variation and I got in.
since then I learned that the vol up and down is after power & vol -, not instead.
I am having a hard time booting into CWM, what is the right key combination? If I hold volume down and power, the Samsung sign comes on, and then the screen goes black and the phone vibrates every few seconds. I'm able to get into CWM just fine in ROM manager reboot and also with Juggernauts reboot, but it could become necessary to do it manually at some point. Thanks.
CWM boot
Need to hold volume up &down plus power keys when U see Samsung sing let power go holding up&down key till U see CWM
Working perfect, thank you!
Hi,
I was on open bootloader, S-On, TWRP and root. For the Stage fright update 4.19.161.13 (Vodafone) i reinstalled stock recovery and applied the OTA. It rebooted twice and gut stuck at One logo for an hour, so i shut it down by pressing Power + volume up. Now it doesn't boot. When i press Powe + Volume up then the One logo appears for a few seconds and then i get a black screen, but when i plug the one into my pc, the pc says mtp-device. Unfortunately i cant get into the Bootloader or Fastboot. Does anyone has advice for me? Thanks in advance.
Hold power and volume up and when the screen goes black you switch the volume to down. Keep the power button pressed at all times and hold these combos until you see the bootloader. Works flawlessly......if it doesn't it's your timing that's off
I'm on vodafone too and had the same problem.
Just follow MrHofs advise to get the screen back.
I have to restore from TWRP to get the phone running.
the update still comes up on my phone now but I'm not going to apply it until I now kow.
Thanks, it worked. The screen wasn't actually black, but on and just really dark gray. In a dark room I could see when it's reaaly off and the press Power + Volume down.
Try this....

Can you help me? My phone is restarting again and again , Even it doesn't stay in Bootloader for more than 2seconds i can even go to fastboot to fix my phone , I am Locked Fully Stock
I have the t-mobile LG G$ (H811) and can't use the hardware keys to reboot into recovery.
I have CM13 and TWRP installed (previously had CM12.1/TWRP with the same issue).
I can use software to reboot into recovery, but not the hardware method.
I have tried all the combinations I can find, basically consisting of:
-turning on and pressing the power + volume down or power + volume down + volume up
-releasing power for 1 second when the lg logo comes up
-pressing the power again
No matter what I try, the phone continues to boot as normal.
I can easily get into download mode though
Is there any way to reboot from download into recovery?
I had a problem with a bad CM flash that bootlooped (not the bad lg bootloop problem) - and my only way out was to re-flash stock and go from there - it was a time consuming pain. I am just trying to figure out some way of booting into TWRP recovery - I can't seem to get the recommended keypress sequence to work.
Any assistance would be greatly appreciated.

Real hard, but I finally got it to work. It is all a matter of timing. Power button needs to be released (and pressed) before the unlocked bootloader message comes on, but not too soon.
Even knowing that, I still only get it right 50% of the time.

I found this sequence to work best for me.
First hold volume down then press power down
When the logo shows up, release power and then press again.
Hi I was running the Cyanogen Mod Nightly for my phone, and hadn't updated it for about a week. When I went in to my settings to update it, I downloaded the latest one and when it was done it prompted me to start it, so I did. It got to about 2%, and after that it's been looping in boot. The screen flashes on and off instantly every 5 seconds. Power + Volume Up works, it shows the HTC screen and says it's going into recovery, but then it just loops in boot again.
Is there any fix/hope for my phone?
Press power + vol up, and as soon as the screen goes black, press and hold power + vol down. You will boot into the bootloader. from here you can flash an RUU to go back to stock

So I tried doing this, but nothing happened.
I did however, fix my problem, by holding down Power + Volume Up until it showed the initial "Booting into recovery" screen (which was failing), but kept holding Power + Volume Up until the Battery Charging screen showed up (I had it plugged into my PC). Once I let go, it rebooted the phone normally, and started up Cyanogenmod. Now the phone works, so I am going to back up my data, and switch to a non-nightlies version (or just never update).
Thank you!
Next time if you are in a bootloop, just holding vol down during the next restart cycle will get you to bootloader.
If the buttom combo (Power+vol up to force a restart, then just hold vol down to go to bootloader) doesn't work, its virtually always due to getting the timing wrong (either not pressing vol down soon enough, or letting go too early). And the fact it was looping makes the timing tricky. But holding vol down during a bootloop (restart) will always get you to bootloader.

I already tried that, it would automatically go back into a bootloop. And I tried your second option, which also didnt work. The only way I personally was able to fix it was having it plugged in, holding Volume Up + Power through the bootloader screen (which would crash) until the battery icon with the red disclaimer text showed up. Then it would reboot without going to bootloader (Pretty sure the Cyanogenmod tried to get it to this and failed).
Still cant get it to update without crashing so im just going to flash a new rom.
