Hello,
For the past week, I've been sifting through the forums looking for a solution to my problem. I have tried the Google Nexus Toolkit and others without success.
Last week, I was running a backup with CW and I MUST have pressed a button by accident. My Nexus 7 has been in the Google Lock screen and will not boot into anything. Power and volume etc... Just goes back to this screen. (see the enclosure).
I was rooted and havent flashed anything to it. I even tried stock cables and others.
Any help would be appreciated!!
Thanks in Advance,
Marty
You can't boot into the bootloader? When you can see that google lock screen, hold the power and volume down buttons. The screen should turn off, continue holding them. And when it turns back on, it should be in the bootloader, and you can let go of the buttons. From there the Nexus 7 Toolkit should work, the fastboot commands at least. Try reflashing a recovery if you can't get back into it, and flashing a rom, stock or otherwise.
Solved Thank You

Ok so, I was going to flash CM 9 v1 on my device, and when i was in clockworkmod recovery I noticed that the power button wasn't working at all.
I took out the battery and put it back and then it reboot itself and got stuck on the unlocked padlock screen.
Then i managed to boot it by pressing vol up and down at the same time and putting the battery in when plugged on the computer with the usb cable. This is the only way i can boot it. And after it runs a while it crashes and reboot into the unlocked padlock again. And this over and over.
Then I tried to go to recovery to reflash with the soft sensitive buttons and the fastboot screen doesn't do anything at all. If I press vol up or down to move around it gets stuck.
Got it to work a while and reverted back to stock rom with rom manager to see if fastboot worked again but nothing happened.
I need help to fix this.
I try to go to download mode but it doesn't work either. ADB works tho
Any suggestion??
(sorry fot the bad english)
i actually had the exact same issue a few weeks ago
it was an issue with the power button itself since i got everything back to stock and the power button still wasnt working properly
i had to send it to samsung repair center
they fixed it for free and it turns out the issue was indeed the power button
thank you for your answer!
i will send it to samsung!
Hey all, requesting some assistance...
I had used the nexus 7 toolkit to unlock the bootloader and root my tablet.
Earlier this afternoon, I decided to cave and flash cm10 on my tablet. Before doing so, instructions stated to wipe. In my ignorance, I wiped one too many things and also wiped the internal memory.
As a result, I am unable to get my tablet to fastboot and when I searched for the .zip to flash, I was presented with an ominously empty file directory to my sdcard's root. I have tried various things with the nexus 7 toolkit and have been unsuccessful in my endeavors, as many of those functions require the tablet to be in fastboot mode before any of them will work.
The device is stuck on the Google screen, and if I push the volume buttons with the power button, it will flicker and eventually return to this screen.
I do have a nandroid backup stored on my machine, but I am unable to use it as I am unable to even boot to the recovery (because I can't get to fastboot)... Any suggestions? I really hope I didn't brick this...
I believe you can get to fastboot mode with the v4.13 bootloader from any other mode so long as the battery is not dead and the screen is working.
When the battery has a good charge, hold the power button down until the google logo appears (could be up to 15-18 seconds). At that very moment that the black-and-white google logo image appears, press the Vol-down button.
Voila. Fastboot.
You do need to see that screen appear though; maybe that's the rub. Note that the timing is important - you only get one second or two to do this immediately after the image first appears.
As a bonus, glance at the bottom of that image. Shows an unlocked padlock for an unlocked bootloader, nothing if locked.
It worked! Thanks a bunch!

No worries. Glad it worked. Actually, I only stumbled across a reference to that button sequence a couple days ago.
If you see someone else reporting that they "can't get to fastboot", let them know - you can get there from ANY MODE.

Hi All,
I've done lots of searching but I'm stumped. Any help appreciated.
Device - Verizon Razr M. New - came with JB.
Rooted using motofail2go JB Superuser. Worked.
Installed Safestrap 3.12 from here.
Was attempting to install EnergyROM following Cheezzzz's Guide.
The instructions don't match what my Safestrap menu looked like, but I thought I had everything going okay. But the ROM wouldn't install. Errored out right away when trying to flash, so I figured I'd boot back to stock and come back later. Now I'm bricked.
The only thing I can get is the initial Safestrap menu after holding Power & Vol up + Vol Dn. It appears for about 10 seconds, but neither the "Recovery" or "Continue" buttons are responsive, then it powers back off.
I'm sorry if this is something simple to get me to where I can RSD, but I'm coming from 4 years on different HTC models, so Motos are a new beast for me.
Thanks in advance,
John
Okay - so I was really just pressing/holding combinations of buttons and I managed to get to the original recovery. Got it in fastboot and am flashing with RSD now.
Edit: RSD flashed back to stock.
Did you have the device plugged in during all this? That stalls Safestrap because the phone is just doing a lazy boot to the battery charging graphic. Glad you fixed it though.

Do you remember the combo you did to get back to recovery? I am having the exact same issue.

Pwr+vol up+vol down until you get to recovery menu. Vol dn until you get to the choice you want, then vol up to choose what you want (vol up is how you select from recovery, fastboot, etc. You can only go down in this menu, not back up. If you miss your choice, just wait and the phone will reboot if you wait too long.) If you choose the recovery option in the beginning menu, you will get the red M and then an Android on its back. At the Android, hold vol down and tap vol up. This will put you into stock recovery.
That combo wouldn't work for me.
If I held down the vol keys and power button, nothing would happen. I tried holding it for three minutes, and nothing. When I let off the keys, the red would pop up after 3-4 seconds and than the SS splash would pop up again without working softkeys.
I came to find that if I started holding down the three keys right when SS splash popped up, I could get into the fastboot menu
Before I begin I must say I've never used an android device in my life so this is all completely new to me. The only experience I've had was rooting and installing CM or something similar to an iphone 3gs a few years ago.
I'm aware a lot of people are having problems with their nexus 7 hanging at the animated rainbow-colored X screen. I've seen the suggestion to hold power and vol up/down to get to the restore factory default settings - but that doesn't show. Mine just shuts off. I've tried going to the bootloader screen via power+vol up/down while the machine was off but nothing ever happens. The nexus just stays powered off. Also, if I hold power while it's hanging on the rainbow X, nothing happens - it doesnt even shut off. In order to turn it off I have to hold power+vol up/down.
I have not rooted or installed any ROMs on this android yet. But I do want to. I am curious if I can somehow root and flash my nexus.
If someone can point me in the right direction on how to start this from a basically dead nexus 7, please enlighten me. I've read through a few instructional threads so far but they all start off with the nexus 7 being able to fully start.
Please advise.
Thanks!

Thanks for the link. I tried entering safe mode, didn't work
- Press/Hold Power button until Google screen shows up, RELEASE Power button
- Press/Hold VolDn until Android has booted up
The device doesn't even boot up in safe mode. Still hangs on the rainbow x.
Got into bootloader using these instructions while n7 off:
- Power+VolUp while booting to enter recovery
- You can release buttons after you see Google on screen
selected Recovery.
It turned off then on, showed the Google screen, and now shoes an android fallen over with "No command." shown underneath and am continuing..
edit: wiped and restarted. can now finally root. thanks bud.
Update: I was able to get it recognized via fastboot and used NRT to flash back to stock under the bootloop option.
Now rooted with factory 5.0.1 !
The way I got it to recognize the tablet was to press the middle part of the volume switch (effectively pressing up AND down volume) and the power button and then the bootloader loaded and I could use fastboot but not adb. I read in another thread about pressing the middle of the sound button. Never heard of that before.
Hopefully someone can help me out.
i updated via abd using the flash all script. Now when it boots up it's stuck on the logo of flying color dots. (yes, I waited 15-20 min at least)
Anyway, now I can boot into fastbboot mode but the computer doesn't recognize it.
If I try to boot into recovery (which I think got corrupted) then I just get the android icon with a red exclamation point.
I have no way to clean anything up cause I can't communicate with it.
Edit: I'm stuck in a boot loop also. If I just let it boot it stays on the logo forever. When I try to turn it off it just reboots to the logo.
If I use the keys to boot to fastboot it just sits there and now I can't even change the option at that point and there's no way to completely shut it down!
Thanks for any assistance you might have.
Pressing both volume buttons and the power button will get you into fastboot mode. It's always the last fallback position and I've never known it to fail. I had the same with a bad flash on Tuesday when trying to solve my wifi problems.
Glad you got it sorted
Thanks.
I was getting to the bootloader screen but couldn't get the PC to see it. I always used to use power/vol down combo to boot into bootloader and didn't even know u could press both vol up and down at the same time.
Or maybe I'm imagining it all.
