hello guys..i'm a newbie in android, and, i have a big problem now. i tried to install another rom instead of the stock one (spanish), and now my device doesn't start at all. i tried many ways, and each time i was able to go to fastboot menu or recovery menu. now, after i've done some steps from this tutorial: http://forum.xda-developers.com/showthread.php?t=491350&highlight=model+incorrect , my device keep restarting by himself. I cannot reach even recovery menu or fastboot menu. It starts the logo screen for 4-5 seconds, and after that is restarting and again the logo, even if i'm trying to press home+power or camera+power. what can i do???
My problem is like in this movie
if i press action button + power, nothing happends on the screen, but the blue led in the right top corners stays powered on. Do you know why?
If you cannot get in to recovery (home + power) or the SPL (power + camera) then you're doomed.
not even with jtag or something, cannot be done?
Unless you physically replace the motherboard (which doesn't look too hard) then no you can't. As of yet there's no Jtag method.

I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!
You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.
I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help
You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up
Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die
Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked
I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.
thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.
You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.
It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932
Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.
I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.
I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary
Hi
need help!!!!!
My phone is completely messed up.
i got an update form LG.
after installing it the phone got suck in boot loop.
I has CWM installed.

1 sec after i get few error codes and then black screen without ADB support.
i trierd to get into download mode after reading in forums that only this can help.
but I can't.
I powered down my phone in all possible methods:

Thanks
Ran :good:
sorry was wrong.
try turn phone off, add usb, then press volume up. I think that's it.
Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Thanks for your help,it sorted out my problem! :good:
Dear experts,
Phone model: Karbonn A9+
Rom: Custom Rom Hyperion Skyfall
When I hold the power button, the phone turns on and off, No problems with that.
However, when I press volume Up+Power, I get a green screen saying FASTBOOT at the top left corner and that’s it. Nothing happens from that point.
when I press volume Up+Power, I get a green screen and holding the buttons past that I get a red screen saying RECOVERY at the top left corner and that’s it. Nothing happens from that point.
However, when I press volume down+Power, I get a black screen saying ENTRY QPST DOWNLOAD at the top and that’s it. Nothing happens from that point.
I have to remove the battery to turn my phone off.
Moreover, I tried a factory reset erasing internal and external storage, after erasing when the phone is rebooted and gets stuck in the start-up screen. I removed the battery and powered on the mobile ,no problem at all the phone turns on but not resettted.
What I did?
Tried to install latest CWM through recovery, updated it but I pressed something instead of restart your device.
What should I do to make everything work again? I am a noob in Android, please be extra patient and illustrative
Many thanks in advance
same issue

I am facing the same issue...today i flashed "ClockWorkMod_Recovery_V6_-_Karbonn_A15.zip" . It was flashed successfully. But after that whenever I try to enter recovery mode using Power+ Volume up keys, it shows red screen... thats it....i do not see typical recovery screen menu. However the screen turns full white. Only option is to take out the battery and restart the phone.
PLEASE PLEASE PLEASE HELP
Please help me. I am in a sort of panic right now.
I have a ZTE Blade C2 v809, sold here in Portugal as Meo Smart A12. It was rooted and working fine. I was however getting some error 24's trying to install apps. I thought this might have had to do with using Titanium Backup to remove TouchPal (I did make a backup first), so I decided to restore TouchPal. There were however some errors in the restore and it was stuck there, so I decided to reboot the phone.
Chaos. Now it wont boot. If I press the button normally, the phone boots, I see the android logo, the screen goes black (Not shutdown black, a sort of light black background) and nothing happens. If I try to boot into Recovery mode by holding the power button and the volume down key, I just get the android logo stuck there, nothing happens. If I hold the power button and the volume up key, I get the picture of that laying down android with the message error.
Any more info I must provide please tell me, I am desperate for a solution, If I lose this phone I wont be able to get another one.
Okay I fixed it. Turns out the recovery menu DID work if I waited for a long time and tapped the screen. Used the update.zip available from the site, and it works like a charm
Yay, I bricked my phone, too.
I did something similar, changed recovery-from-boot.p name to recovery-from-boot.p-bak and install-recovery.sh to install-recovery.sh-bak
Now the phone doesn't boot properly, in fact it's stuck in a boot loop:
>starts
>shows white ZTE logo on screen
>restarts
Tried connecting the phone via USB cable and used fastboot devices & adb devices commands, no devices found.
Also tried pressing "power + vol down" and "power + vol up", nothing. I can't enter recovery mode or bootloader.
Apparently the remaining way to get in it's trough the SD slot, or maybe there's another way.
I kindly ask for help, couldn't be possible that I ruined this cell phone so fast.
Ideas, somebody?
So i have no clue what i did but my phone first got stuck at the part where it shows the one plus logo in the middle and says "powered by android" at the bottom for seconds and it going black . But i figured out that if i hold the volume up button i can get to fastboot mode but i cant do anything else. Can someone please help me!!
Did you try installing any custom firmware, or android layer theme earlier? You might wanna try to boot into recovery and perform a factory reset. Press volume down, and hit the power button, after the Oneplus logo show, few seconds after, release the power button and keep pressing the volume down. The recovery menu will pop-up and then you can navigate to factory-data reset. Please not that doing this will wipe all your data and storage... so think it over. Let me know if this helps.
