[Q] Access Recovery via ADB/Fastboot Without Bootloader First - Nexus 7 Q&A, Help & Troubleshooting

Hello Nexus 7 community,
Today my brother complained to me that his Nexus 7 (2012) was stuck on the new KitKat boot screen. I suggested he let it sit. Fast forward an hour and it was still stuck at the boot screen, so I held the power button down and it shut down. But now the tablet can't get past the "Google" splash screen and becomes stuck in a boot loop there. I can get into the bootloader with ADB and fastboot, but when I select "Recovery mode," the top right corner of the screen says "booting failed" and I am given the option once again to choose recovery mode, start, power off, or reboot bootloader.
So I'd like to ask if there was any alternate way to get into the recovery by bypassing the bootloader. I figure I might be able to re-sideload the JWR66Y-to-KRT16S OTA.zip to fix the issue. Otherwise, I don't know where to turn. This is a locked, non-rooted device, and I'd prefer not to have to wipe the data.
Thanks!

Stuck at Google screen

I tried to format something in Recovery (CWM) this morning (like system/data/ect...). What an idiot :crying:
And now it stucks at Google screen. I can't go to fastboot mode, or bootloader. Everything stops at Google screen. I tried to use Nexus 7 toolkit or Nexus Root toolkit to back it to stock, but can't. It requires fastboot mode to do this.
Help me, please :crying:
Everything is OK now, it went to fastboot mode magically, what the ... fruit ?!
Delete my topic, please, i dont want to be a spammer
No magic.
If you press Vol-down the moment that the Google (black-and-white) splash screen appears, it will jump to fastboot/bootloader mode. Doesn't matter where you started from. Same result from cold start, bootlooping or running OS, or in APX mode.

Is my Nexus 4 bricked or irreperably broken?

Hello people,
I have a German Nexus 4 and it gets stuck in bootloop whenever I turn the power on.
I've had issues with the phone since the last few months - i.e. random reboots, random program crashes.
But recently I tried to root it in order to install the Android L developer preview. It was during the booting process, when my Nexus crashed and it has been unable to boot ever since.
When I push all three buttons (power + 2 volume rocker buttons) simultaneously, I get the fastboot screen.
Choosing the following options has these effects:
Start --> phone tries to boot but gets stuck in bootloop forever and ever
Restart bootloader --> restarts the fastboot screen
Recovery mode --> phone shows the robot with an opened belly and a red warning sign (see photograph)*
Power Off --> turns the power off
Also, it is NOT detected or recognized by my Macbook when I connect the Nexus via USB cable. So it's impossible for me to access the phone via my Macbook.
*This is the screen shown when I try to go into Recovery mode in fastboot:
[can't upload outside link to image]
So this leaves me with no options as I never get further than the 4 turning circles forever and ever.
Is my Nexus 4 broken or is there still a chance to unbrick it? (I have a MacBook, so Windows programs won't work for me)
Of course it's not possible to recognize it when OS is not running.
Download WugFresh toolkit, ADB drivers (Universal) and the factory image. Enter fastboot, connect USB and flash the image
Your phone is not hardbricked, because it boots into the bootloader.
It might be recovered if you can access it with fastboot.
Try uninstalling all related drivers and install the Naked Universal Driver.
Thanks for your replies!
Unfortunately, the programs you mentionned don't work on my Mac (they seem to be Windows-only).
Also, how can I install stuff on my Nexus? Since it is not recognized by my MacBook, I can't load any files onto my Nexus.
And since any command on the fastboot screen only leads to the phone powered off, restart of the fastboot screen or the mentionned bootloop, I cannot perform any actions on the Nexus ...
Go to a friend with Windows.
Problem solved!
Somehow after the 1000th bootloop I finally reached the screen where I could wipe the phone.
And then it finally booted! Now all the data are lost and it's like a new phone, but at least it's working again!
How long was the boot loop? Was it the new boot animation from L?
Because when you flash L, the first boot up may take up to 15 minutes, leading you into thinking it's a boot loop.

[Q] Nexus 7 Stuck booting to Clockworkmod Recovery v6.0.3.1

I was just given a Nexus 7 2012, it seems it's somewhat bricked. When turned on, it boots passed the Google screen to ClockWorkMod Recovery v6.0.3.1, on the scren, but the menu doesn't come up at all, and none of the buttons do anything, and no matter what combo of buttons I try, I can't get it to bootloader mode or anything else, so recovery toolkit won't find it because it can't fastboot/adb. Any ideas to rescue this thing?

Need help to unbrick my phone

Hi,
I have a Note 4 t-mobile that is "brick" right now. and I hope if anyone offer assistance.
It is running Android 6. Ever since the last upgrade the phone would freeze and reboot on its own. I fixed that problem by installing Wake Lock. After that it would still experience sluggish at time but the phone is still very much usable.
Lately, after watching a bit of streaming video the phone would slow down so much that a reboot is needed. But yesterday my last reboot turned my phone into a brick. After that reboot the phone rebooted itself to the download mode. So I took the battery out, waited for a few minutes and put the battery back in and started the phone. Instead of booting normally the phone displayed the message including "set warranty bit: recovery" and then followed by the flashing TWRP splash screen. By "flashing TWRP splash screen" I mean the TWRP splash screen ( with the TEAMWIN logo) would be shown on the screen for a second, then the screen black out for a couple of seconds, then the splash screen is back on for a second, and the screen black out for a couple of seconds, etc, and never successfully boot into TWRP recovery. I had left the flashing splash screen overnight and nothing changed. Connect the phone to my pc via usb and fastboot wouldn't recognize my phone when phone was flashing the TWRP splash screen. So I tried to flash TWRP again by starting my phone in download mode "volume down + power". When I connected my phone to my pc Odin recognized my phone. But when I tried to flash a custom recovery (TWRP or CWM) it seems the download started but never finished (on the phone I could see the progress bar started but never progress further).
Any suggestions would be greatly appreciated1
Additonal info
I just wanted to add that my phone is still running the stock ROM.
Problem solved
Problem solved. Once I used a different cable and the download process actually worked and I was able to flash stock ROM using Odin.

Tab M8 HD Stuck in "Meta Mode"

Hi. I've had my Tab M8 rooted with Magisk for a while. However, I'm an idiot, and thought I could do an OTA update and everything would be fine. Well, no. Now my tablet is stuck in a bootloop (Stuck on bootloader screen, never gets to OS boot.) The tablet doesn't respond to recovery mode keys, and attempting to put it into fastboot mode flashes "Meta mode" for a split second and goes back to the bootloop.
Any help is appreciated. I'm happy to provide any additional information.
