Hold down power button with charger plugged in for 30-40sec.

And bricking usually implies you did something to it; so what lead up to this?
And I agree; I suspect your battery is just dead. If you haven't yet, leave it on the charger for a few hours.

Mehrab,
Your sentence above is a little vague - I think you are saying that you can not get into bootloader/fastboot mode, and from there you can't subsequently get into recovery mode. Is that what you are saying?
It is possible that the tablet is simply in APX mode; to exit out of that, hold the power button down for 13-20 seconds. Get ready! As soon as you see the Google logo appear, you need to immediately press the Vol-Down button (within one or two seconds).
It doesn't seem to be well understood by N7 users, but when a hard reset is performed by pressing & holding the power button, the Tegra3 SoC always attempts to invoke the bootloader. It doesn't matter what mode you are starting from! (although it does seem to take a different number of seconds, depending on starting conditions)
That black and white Google logo is the bootloader - giving you a 1-2 second opportunity to hit the vol-down button to enter fastboot mode... rather than defaulting to a boot of whatever is in the boot partition.
So - if you can get the Google logo to appear through any means, be ready and press vol-down quickly!
If you can not get that logo to appear, for the moment you are out of luck as APX mode has not been exploited successfully at this time.
Good luck.

[Q] Hp Touchpad - black screen "Please release key(s)... HELP

I have a 32gb Touchpad. It has been running CM7 fine (dual boots that and WebOS) since June 2012. The battery had completely died so I plugged it into the power adapter. After it had charged for a few minutes it started to go threw the process of loading. The hp logo came up as normal and then a black screen appeared with the message "Please release keys..." I tried keeping the power button pressed down for eternity does nothing (I've rebooted if the Touchpad has gotten frozen before or if the touchpad didn't recognize touch on the screen).
Please help, I have no clue what to do. I googled the problem and it seems people have this happen when they install CM, but mine's been running fine for months and this is spontaneous.
Sounds like your home key is stuck!

Touchpad Boot Loop due to Stuck Home button

I think this is what I have been experienced :
Have done some significant research before posting but have not found a clear match to my problem. I bought two Touchpads for my daughters when on fire sale (lucked out with OnSale), and they have been running with CM9 with no problem for several months. One of them last week would not boot and after some charging it appears to be stuck in a boot loop. I have charged it for several days to try to eliminate battery issues with no luck, and I suspect something other than charging...
Here is what it will do :
If I hold home and power to reset, it will momentarily show the HP logo, then the Moboot menu, but it instantly flashes to a Cyanogenmod boot with no waiting (first clue that the home button is stuck ????). The unit then tries to boot but the display will not stay lit. Occasionally when the unit is resting on the Touchstone I can see the clock like it has been booted into CM9, but I cannot interact with the touch screen at all, and the clock will not stay on the display.
If I try to boot and bring it into recovery mode, I can hold the Volume Up after releasing the home and power and I get a blue screen and the message to "Please Release Keys" (another clue that the home key is stuck ?).
From this position it runs the boot loop again, with no opportunity to interact. Can't get it to recovery so it is a paperweight at this point..
I see my options as follows :
1. Keep trying to charge to see if it is just a battery charge issue, but if I see evidence that it is booting into CM9, that steers me away from this solution
2. Let it discharge cpmpletely and then recharge (don't really like the risk of introducing a battery issue where there isn't one...)
3. Crack the unit open and try a replacement of the home button
Would appreciate any input.
Thanks
Todd
You might try using adb.
In the terminal navigate to the folder with adb and:
adb start-server (to start adb)
adb devices (to confirm the Touchpad is recognized)
adb reboot recovery (to boot into recovery)
adb reboot recovery should be entered while it has the boot loop in process

thanks for the reply. Installed the SDK and ran ADB,but it does not recognize the Touchpad - have tried reset, all manner of button combinations and it won't list it as a connected device.
Any other ideas ?
Thanks in advance

I don't think that your home button is stuck. If it were stuck, the screen would read "please release keys" as you have seen when holding the volume buttons while booting. Based on that, I wouldn't suggest attempting to replace the home key.
It's likely that debugging was not enabled on the Touchpad before the issue started, hence why adb cannot connect, which is unfortunate.
I would suggest that you might try pressing one of the volume keys in rapid succession while booting into moboot. That may get you the opportunity to catch the boot menu before the timeout (sounds like it has been set to "0" somehow).
Well I got it to do something...
I got it to where my PC would recognize a Palm / Novacom device and was able to run WebOS Doctor, which is great. What is not so great is that I get no display, although I can tell the unit is booted into WebOS (I.e. I get a tone when increasing / decreasing volume and I can get the camera to fire by pressing power and home.
After a reset and putting it on the touchstone it appears that WebOS is running fine, but there is nothing on the display.
Best guess now is just a bad display that can be replaced,correct ?
Thanks for the help

[Q] how to enter stock recovery in JB

Hi all,
My phone is EU retail, locked, unrooted. I updated from ICS to JB via manual download of the update and installation via SD card as explained in one of the more popular threads here. Now after the JB update, I want to enter recovery in order to clear the cache.
With ICS, I was perfectly capable to enter the stock recovery. Press power + vol. down for a few seconds, and the (fastboot?) menu appreaed where I could select recovery. Then the dead robot shows up, I pressu vol. up + vol. down and I had the expected options. Now on JB however, this does not work. It does not matter how long i hold power + vol.down, it always boots the system. When I press power + vol. down and keep holding the two buttons, the green LED goes on and off, then the phone vibrates, showes the red M and seemingly starts to boot. Then the screen goes off and it repeats the 3 steps (LED, vibrate, red M) but then goes on to boot up the system...
Is this supposed to happen?
Same here. It looks like there is no Recovery installed at all, so will try to flash one tonight.

I'm new to Motorola so need to ask...what is this stock recovery for? Is it the same as a typical 'custom recovery'? I've never heard of a manufacturer putting on in their ROM...so can I do a normal backup of a ROM or no? Thanks

Thanks, this releasing of the power button while still holding vol. down works reliable to get into fastboot. However, when I select recovery, the screen goes black? Something is not quite right with my phone...
Edit: I seem to get the hang of it. Now I finally get into recovery. When I select it from the fastboot menu, the screen gets black for a couple of seconds and then the dead robot appears. To get the options in recovery, I press both vol up + down at the same time twice. Initially, the layout in recovery is broken up. Just two blue lines at the top and a few characters in green at the left border. Once I press any of the volume buttons, the options finally appear.
Hmm I have not gotten into recovery on JB even once...can't get in.
help please!!
i have de same problem
when i push power button, the green led turns on for a few seconds and then the phone get off... i can not enter into recovery mode either
anyone know how to fix it or fix it already
thanks!! :crying:
The above tip doesn't work for me - either my timing is wrong or I don't understand the instuctions.
Someone else kindly explained it differently and eventually I got it working. That was posted in some other thread and I don't think it was directly related to recovery - I can't even find that post now!
I have found people saying they've got root on the RAZR M on locked bootloader Jelly Bean...but you need to access stock recovery which I can't do now.

That's the original post...I don't fully understand it.
I am grateful to that poster for trying help people - so I don't want to be misunderstood! :good:
If I were to describe the boot process to someone, nothing 'vibrates' - so I don't understand that. My phone doesn't vibrate when boot begins, and no 'i' vibrates either. Also, there are two 'i's. There is the i in Intel and in Inside. I'm guessing it's the first i. Believe me, I have tried 10 combinations like 50 times. I know it can be done, but can't do it using that post.
Nope, someone else explained it differently and I got it the first time. It wasn't a recovery thread so it's hard to find now.
Your Razr does not vibrate after boot? This is strange. Ok, let me try to describe the process based on my Razr i. (As simple as possible)
1. The mobile is turned off
2. Press and hold the Vol- button
3. Now press and hold the Power button and observe the green light. It turns on at the same time I press the Power button. The green light is on for approx. 2 seconds than it turns off.
4. Just at the moment when the green light turns off my Razr vibrates twice within 1 second.
5. I need to release the Power button before the 2. vibration and at least 0,5 seconds later the Vol- button. This is the point to get in the fast boot menu.
Without any vibration you should try to release the Power button just at the moment when the green light turns off - followed by releasing the Vol- button 0,5 seconds later.

[Q] moto RAZR I stuck at boot logo

My phone ran out of battery on the way home this evening after charging it up i turned it on and the device is just sat on the Motorola 'M' boot screen
i have tried a soft reset (power and lower volume button) but it just comes to the same screen, i have taken out the sim and SD card and it is still doing the same how can i fix this?
You need to get into the boot menu.
Turn on and hold power and Vol down. Release power when it does the first vibrate but do not let go of the volume button.
Its a bit temperamental until you've done it a few times to get the timing right.
Leave your Sim and sd card in.
If battery is dead the led only shows green when trying to turn on so that seems fine if you can get to boot logo.
It's probably having a hissy fit like windows does on a hard shutdown and needs safe boot to fix

Nothing to worry m8. Something ****-up with system files maybe There is a lot of threads about such bootloop
As far you see any logo your phone is fine you need enter to fastboot and flash stock firmware with rsd-lite. How enter fastboot you can find on forum.

My Nokia 7 Plus does not boot at all or stuck on Android One logo

My phone suddenly restarted and stuck on Android One logo and not booting further. I've turned the phone off and started after few seconds and it was still stuck on Android one logo. Then I've tried to get into recovery mode by pressing Vol Up + Power but it was not working. Also it's not responding to the charger. No battery sign and nothing. It does not respond to power button many times. I've also tried to get into fastboot mode (Vol down + Power) and even it was not working. Please help!
It's not rooted and didn't try to flash/install custom ROM.

Take phone to discharge batttery and automatically turn off. Plug in to charger for few minutes and press and hold volume up,volume down and power for 2/3 minutes. He should be turn off and then you can go in to recovery.
Suffering the same problem.
I'm having the same problem. Exactly what you said. I didn't root my device or even attempt to do anything. I bought Nokia because they were purely stock and delivered some quality mobile phones. I've got only this phone as my daily driver. So tell me if you have got the issue fixed and how much did it cost and how long it took. It's been stuck with that 'android one' logo and a small message that reads 'Download mode' on top. I've tried everything. And what I'm worried about is, my phone's out of warranty and I'm a student. I hope you got it fixed for some reasonable cost. Please reply to me ASAP.

Possible brick after updating twrp

Dear all,
I was on beyond 5.3 with twrp 3.3.1.7 and I wanted to update everything. Magisk, root etc was working fine.
I downloaded the patched twrp file from the beyond telegram chat and flashed it as image into the recovery partition.
The installation was finished in 2 seconds, but stupid me chose to power off instead of rebooting the recovery.
So I tried to enter recovery using the button combo but nothing happened and I was stuck with the samsung logo.
The current status is that my phone only shows the samsung logo.
Holding the power button for a minute doesn't do anything.
Pressing the button combo for recovery mode doesn't do anything.
Pressing the button combo for dl mode makes the phone reboot. It vibrates for a sec, then the samsung logo shows again.
If I keep pressing all 3 buttons the phone keeps on rebooting and vibrating each time, but dl mode never appears. If I let go of the power button the logo stays and again, nothing happens.
So basically I can't enter dl mode nor reboot.
Should I let it run dry and try again or just throw out of the window immediately? :crying:
I let the battery drain over night. Phone was finally off.
So when I plug it in, the Samsung Logo appears and doesn't change. It just stays like that forever until the battery drains.
Pressing the power button doesn't do anything, no matter how long. It doesn't reboot nor does the logo disappear.
Pressing vol+, bixby and power again does nothing.
Vol-, bixby and power makes the phone reboot. The screen turns black, the phone vibrates shortly, the logo reappears. If I keep pressing the buttons the phone reboots again, and again, and again, mever reaching download mode.
If I let go of the power button and keep pressing vol- and bixby the phone stays black and won't even show the logo. Nothing happens. If I let go of either of the two buttons the logo appears again.
It won't boot, won't go into recovery or go into dl mode.
I'm doing all this while it's plugged into the usb port of my pc, and it doesn't get recognized. Samsung 300k tool doesn't recognize it either.
Now I know the meaning of "bricked" lmao.
Does anyone know how to possibly fix this?
Pressing only the power button for a minute literally does nothing. Like hell, how is that even possible?
You can try this to go to download mode:
Vol down + bixby + usb cable connect to PC
It's advisable to charge battery first before flashing firmware.

I tried that for like a thousand times already but now it chose to magically work somehow.
I think I peed myself a little when that ugly turquoise screen appeared and I screamed from sheer happyness.
THANK you!!!
The problem that doesn't stop giving lmao.
Got into DL mode, got odin to start, but after like 10 seconds my phone dies and odin fails.
Now I cant get into DL mode, but rather only the "an error occurred while updating the device software. use the emergency recovery function in the smart switch pc software."
Could it be the battery that simply dies?

Yes most probably a discharged battery. Hopefully you can go to DL mode again after charging your phone.
hello,
I've and S10e and because an important app to me I need to go back to android 9 where it works.
I've read a lot info about downgrade, but no one says ROOT/UNBRICK.
Can someone inform if there is a way of downgrade without ROOT (maintaining the warranty).
thanks in advance
P.S.: Maybe too naive question, sorry for that
