[Q] Brick Nexus7,please help - Nexus 7 Q&A, Help & Troubleshooting

I try to upgrade it to 4.2 and it failed.After all, it stuck in Google logo.
I hold the power button for 10secs but it reboot automatically.
And I used power+down volume but it failed to load into bootloader or fastboot.
Please help!!!!!! Is it any way to solve it? Or I have to send it back to AUSU?
Thanks in advanced.:crying:

I just went through the same thing on my device.
Try holding both volume keys + power to reboot in bootloader/fastboot.
From there I followed this guide http://forum.xda-developers.com/showthread.php?t=1907796
Even the stock 4.2 image is there. I just booted stock 4.2. Just need to root and flash a custom recovery.
Good luck!

[Q] Cyanogenmod 10.1(or 10.2) stuck in bootloop? D:

So about a few hours ago I saw that I could download the new 10.2 cyanogenmod. I wanted it because it was Android 4.3, so I downloaded it. I tried watching flash movies and stuff, and the browsers and stuff kept crashing, and the internet didn't work completely. So, I downloaded 10.1 again, and installed it. It rebooted to the teamwin thing, and then rebooted again. A few minutes after, I was curious as to why it was still loading. Waited a long time, and it still was on the CM boot logo thing. Im using the Nexus 7 toolkit (its called something else, but im not sure what. The icon is a red toolbox with 3 tools in it), and can't reboot into recovery or flash stock back on it. How can I get it out of bootloop? I really need help! D:
Press all the three buttons , power , volume up and volume down together and boot into bootloader. From boot loader use volume buttons to go onto recovery , do a clean wipe there and reflash a ROM. Another alternative is to use adb and type
Code:
adb reboot recovery
then wipe clean and reflash ROM.

Hi Red Devil,
I just tried to install CM 10.1.3 on my Motorola Atrix HD.
I forgot to wipe data and cache before installing the ROM, and now it is stuck in the boot animation.
When I press the power and volume keys down together, it takes my phone to a black screen, and when I press them again on the black screen it gives me a brief menu that says
"Normal power up"
"Recovery"
"AP Fastboot"
"Factory"
and another one I can't recall.
This screen times out in about 3 seconds. and regardless of which item from the menu I select, it still shows my boot logo, then the CM animation. I cant boot into fastboot or recovery, and I can't find anything good online to help me.
Help! What do I do?

[Q] Cyanogenmod Stuck in bootloop, Can not boot into recovery.

I have installed CyanogenMod on many devices before, and have never had as many issues as with the LG G2.
I was able to install CWM Recovery, and I used that to backup my existing ROM, and to Install CM-10.2, the build for the vs980.
After installing, and rebooting, I am getting stuck on an infinite boot screen. And I have no idea how to bot into recovery.
The default boot to recovery / factory reset screen is supposed to be, holding the power button until the LG Logo appears, then prelease, and hold again... This does not work, it just goes right back into trying to boot CM.
If I hold Power + Vol+, I enter some Firmware Update screen.
How would one enter CWM Recovery using only hardware? And how can I fix my infinite bootloop?
Any and all help is greatly appreciated.
**Edit**
I found out that I was going into this mode, and not recovery / factory reset... because I was still plugged in via USB... As soon as I unplugged, I was able to do this as expected.
Mod, please delete. I am unable, and I have solved my own problem.

[Q] VolDown button not working/always booting in bootloader

My stock Nexus 7 (4.4, kot49h)'s volume down button is not working. Not even in bootloader (4.23) . Because of that, everytime i reboot it goes in the bootloader, not in system. And from bootloader I'm only able to go to safe-mode. I tried flashing a newer version of bootloader, and re-flashing the stock ROM. I can only use safe-mode.
Any solutions? Should I take it to the service and wait or there is a faster method of solving this problem?

[Q] Can't Boot/ NO STOCK RECOVERY option for LG-D802? (D80220b-HKG-XX) Any ideas??

Recently i have updated the phone from 4.2.2 to 4.4.2 by LG PC suite and OTA upgrade. During 4.2.2 i am able to boot into stock recovery by pressing power + vol down button, but after upgrade my phone was unable to boot into custom recovery nor hard reset. The LG logo just appear and disappears (Like how you force shutdown a phone).
My phone is unrooted and no custom recovery has been flashed. (I was a little worried for flashing custom recovery and start rooting since i cant boot into stock recovery in D80220b-HKG-XX
Does anyone experiencing this or is recovery accessible only after custom recovery has flashed?
Thanks.

Hi, There's many, MANY threads talking about NOT upgrading with OTA, instead install custom recovery and flash thru recovery stock KK with SuperSU.
I (and many) don't trust OTA for the same reason, sometimes something goes wrong and you have no custom recovery and no Rom. If you don't have experience rooting, unlocking, so on ,,, your best bet is go to your cell company and tell them you took OTA and your phone broke, they should be able to give you a new one since you don't have ROOT or Custom Recovery.
Hope this helps

NP, yes just go back to JB ->root -> TWRP -> flash stock KK -> flash SuperSU 2.x ->profit
If you want TWRP in KK just intall AutoREC.
The reset process is changed since 20b (i think I'm not wrong!?)
1. hold power + volume down until you see the lg logo --- release shortly (just release and after releasing 2.)
2. hold volume up + volume down instead of volume down + power

Wow It works! But it booted me to hard reset mode, is there anyway to boot into recovery mode? Or am i only able to boot into recovery once i flashed custom recovery like TWRP?
Thanks a bunch sir!

once you flash TWRP via autorec it will take you back to twrp (the old combination)
For now you can't boot to recovery(you might try "adb reboot recovery" - it might factory reset if this is your fresh installed kdz

Absolutely correct and these type of answers are incredibly HARD to come by since most of the youtube vids + google search results are methods prior to the 20b update.
For the users out there with the latest update, they will have a hard time searching for the right combination. With the latest update, pushing down button + power key again and holding it will only result in the phone powering off.
For the ultimate method, use ADB reboot recovery via PC to access stock recovery.
(If you have rooted your G2 before via IOROOT method, you would have noticed the existence of the G2's stock recovery menu when this command was executed by IOROOT during the root process.)
*Be Aware* Holding the Vol Up + Vol Down key will bring up the Factory Hard Reset. You only enter YES if you're confident you have TWRP custom recovery installed, it will not perform a hard reset but instead load up TWRP immediately. This is the only way to enter TWRP through the phone. But if you had stock recovery it will erase everything in your phone! (incl. camera photos and vids)
I've heard something about bricking the phone if custom recovery was installed and OTA update was performed. With the imminent Lollipop official release, most users need to be aware of this or refresh their minds readily to avoid themselves another round of headache...
Boy these LG phones are complicated to mod as compared to the Nexi or the Galaxies....

Need help desperately :(

Are you getting to the factory hard reset prompt? You have to go through that to get back into the recovery. Then you can just restore from Backup.

--This is copied and paste from another thread--
"You should be able to get to CWM recovery by using the hardware button (power and volume down held down, flash LG logo for a second, and then shuts off--only then you can turn it back on by holding power and volume down together until LG logo pops on, then let go of both buttons quickly, hold down both power and volume down again, and then quickly let go of the volume down button: a white factory reset screen should pop up and then you can push power button alone twice to enter CWM recovery).
If above does not work, you may need to KDZ back to stock using download mode (google LG G2 download mode) and USB cable (the one that comes with the phone as some USB cable won't work as they're charge only cable). You'll have to reroot with IOROOT25 and start over again."
--
I have no idea what fastboot or download mode is but your phone should be soft-bricked? If you can get into recovery or the factory reset screen you should be safe.
I wasn't able to get into the recovery at first but then I kept trying and trying and managed to get in by luck. Lol. I then wiped everything including Dalvik cache in Advanced and rebooted and was relieved to find it booted into Dirty Unicorns. I guess i was lucky.
