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?

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
OK, I managed to really really screw my phone up!!!
I installed a 4.4.2 rom (crDroid) and everything was working fine.... USB debugging on and rooted.
Next I started playing with LCD Density settings and managed to get get a device that won't show anything past the LG logo.... just a blank screen.
I have tried connect it to my computer and using adb to push a new build.prop to fix it, but I can't seem to get this thing recognized via adb anymore.... all I see is an "unauthorized" device and I can't see the screen (b/c it blank) to make any changes to actual device.
I am really really worried that I have completely borked this device.... PLEASE PLEASE PLEASE HELP ME!!!!
Another thing I should note.... I have tried many many times to boot directly into CWM (which I have installed version 6.0.4.4.). Unfortunately I think the LCD problem is killing me here.... I hold down the power+vol-down and then press them again when I hit the LG logo, but at this point the thing just goes blank.... I never actually see a CWM screen.
Again, thank in advance for your help... I am very very desperate and really have no idea what to do at this point.
OK, sorry for the freakout... I got this sorted out... it turns out I was following the wrong instructions on how to get into hardware reset mode.... for the vs980 you need to do the following...
1. press and hold power + vol-down
2. as soon as you see the LG Logo...
- release the power + vol-down buttons
- then immediately re-press only the power button
This should do it... some people were (I'm guessing for the other versions of the G2) were saying you needed to "re-press" both the power and the vol-down button and this was not working for me.
Hello guys, I'm new here and I hope you can help me out.
Let me make the story short.
My phone's screen broke and I replaced.
In that processes I lost the rubber that stick
to the panel of the volume. I was fine with that since my phone
in vibrate mode and I really don't use ring tone in my daily basis.
I tried to download Android 5.0 lollipop and flash it.
How did I get there? well since I did not have a volume button,
I downloaded an app that restarted my phone and got me into
fastboot mode without the key (I did got me where I wanted).
Then the problem was that in the middle of writing the .img
the freaking cheap bastard micro usb unplugged!!!
BAMM!! phone now is bricked, I cannot get into recovery/fastboot mode
since I cannot press the volume key and my phone is bricked.
I tried going through fastboot mode via my computer again,
but the computer doesn't recognize the device since it still
looping there forever at the google logo. I try installing USB
DRIVERS to see if I could do some "magic" haha. Got
error "This device cannot start ..." And still at the same problem.
I know I can get back to my recovery if order the part for the volume
key, I ordered the part to replace it, but trust me I was 3 weeks without
my phone and now this problem
Is there any way that I can get to fastboot mode to factory reset my phone
without volume key with a bricked forever looping a "google" logo ? :fingers-crossed: :fingers-crossed:
I appreciate any help.

Im not sure why your text is like this? But paraphrasing buddy comes a long way
Just hold the power button, until it dies, or just let it die in general since your volume button (You only need Vol down and Power) to power it off completely. Since your Volume keys are gone, the best solution is to wait for the replacement before doing so, unless you can get the contact keys to trigger the Volume button, you're in a loss atm. No OS or Volume keys means you can't trigger ADB commands or boot into fastboot. Just wait it out I guess?
Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
--------------------------------
Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.
Rgrds,
Ged.
Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad
Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

https://forum.xda-developers.com/showthread.php?t=2455927
https://forum.xda-developers.com/showthread.php?t=2340237
I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.
Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
