Normally you press power button and reset at the same time. Let go reset button while keeping volume button pressed
for a further three second or till it beeps. Otherwise download https://play.google.com/store/apps/details?id=pl.qbanin.reboot.
Execute from app drawer.

Thank you for your kind reply,
i tried this method but nothing happened,
also i tried different recovery apps but all needs the device to be rooted & unfortunately my device is not rooted.
and i have no clue how to root it while i have no USB cable for it to connect to notebook or PC.

To root, try going to Factory Settings, and where you would normally enter the numbers, enter the following: *#hct#root# push enter, you should get a pop up message that says ADB ROOT - test by installing an APP that requires root and see if it will get root permissions - if that doesn't work, you can also try installing Kingo Root, which has worked for me as well - https://www.kingoapp.com/android-root.htm

[Q] Galaxy Tab 3 7.0 Won't go into recovery mode

I have in my possession a Galaxy Tab 3 7.0 inch, that will not go into recovery or download mode. When you hold the power and volume up button it starts regularly, despite the fact I have several other Galaxy Tab 3 7.0 inch tablets that do go into recovery. I cannot get it to go into download mode either, so I'm stuck as what to do. I have confirmed that the volume keys do indeed work, I can change the volume of music with them after the system has started.
My goal is to do a factory reset on the device, is there some trick I can do via USB to put it into recovery? Or maybe do a reset over USB?
Any help is greatly appreciated.
Yeah it can via adb shell and you know you should hkld home button top?
Brought to you by SM-T210R
concerning button combination to recovery/download modes
apparently the home key is not needed on p5210 at least, only power &vol+ =recovery
power & vol- = download mode
edit; tab 3 7.0 does need 3 button combo
check root by opening terminal and typing su
if return with [userid]# then you have root
type whoami , should return uid0 or command: not found , means no busybox
at root prompt # , type reboot, or reboot recovery
okay so [edit] my thought is your home button may be boned or sticky/dirty
a side question, i need to know commands for following if they exist
i need to know what the BOOTLOADER outputs by way of log if there is one
i need another way to get mmcblk names as the cat /proc/dev device by name
isn't present on my tab.
i do apologize for unrelated questions, but couldn't see starting new thread for that
i don't mind pm's so please feel free. thanks for reading
:good:
For download mode
Keep pressing
Power + volume down + home key until it vibrates
And for recovery
Power + volume up + home key until it vibrates

Thanks man, i solved it. I was trying to use flash tool but it doesn't work, i'm gonna try with your solution.
-------------------------------------------

You already have stock recovery
Whenever the Android guy with ERROR shows, press and hold the power button for 1 sec and then while holding it, press the volume up button. It will bring out all the recovery options. Cheers...
Thanks, worked for me too ! (just i used volume up + power instead of volume down).

Bricked Head Unit RK3188 - Please Help

I recently upgraded to the eonon GA6151 and was trying to flash update_RK3188_1024x600.img " booroondook RK3188" , well I renamed the file wrong to dupate.img instead of update.img I started flashing it and it was too late before I realized. Now the unit will not boot up or go to recovery. I can reset it and see the buttons flash like it wants to go to recovery but nothing ever appears on the screen. Is there a way to adb into this unit? Can I put files on a card and have it auto install them? Any help would be appreciated.
FIXED IT!!
I fixed it using this method. I realized after the fact that this new unit is MTCD not MTCB.
https://forum.xda-developers.com/showpost.php?p=67184851&postcount=50
I then had the error
https://forum.xda-developers.com/showpost.php?p=67309331&postcount=116
Which I fixed doing this
https://forum.xda-developers.com/showpost.php?p=67598154&postcount=319
I used the dupdate from here.
http://huifei.fs-fileserver.de/content/firmware/MTCD Custom ROMS - NOT FOR MTC-/RK3188/2017.02.21/
I loaded it onto the sdcard and the usb drive , the sdcard was created using upgrade disk tool and has to be 16gb or smaller fat 32. The usb drive just had a copy of the dupate.img file on the root of it.
To get into recovery on this unit do the below. http://www.eonon.com/Android-Car-GPS/Vehicle-Specific-GPS/GA6151.html
Press and Hold HOME AND POWER buttons
Press RESET while still holding HOME AND POWER
Let go of HOME AND POWER and then press HOME AND POWER down again and hold until the lights flash 3 times " is about 10 seconds to hold them "
Now Let Go of the HOME button then the POWER button the press the POWER button once "do not hold" and wait for it to boot into recovery.
This is the only method I found that reliably will get you into recovery. Make sure you use the GPS slot for any sd stuff you need to do in recovery.
Did you have to take the unit out of the car? I’ve made the bootable SD but nothing is happening.

Need help using CWM to recover data

So my screen blacked out and I would like to attempt and retrieve the information off of my phone. I have an idea to use the CWM I have installed on my phone and from there mount it. But since I cannot see the screen, I was hoping somebody could tell me the number of presses of each button so I can mount it. Thanks!

not sure if cwm will help, but twrp 3 will definitely help, i want you to boot into download mode and flash twrp 3 using Odin, and then boot into recovery.
TWRP 3 has MTP enabled by default, so when you're in TWRP and connected your phone to PC, you will see your phone on PC and will be able to copy anything you want.
also you can use adb pull commands but it requires usb debugging on in your rom.

yes, you will do it blindly, but it's not hard.
you press power + home + volume down for 3 seconds, then press volume up, and connect your phone to PC, then flash the TWRP 3 using Odin,after the flash is done, remove battery, and insert again, then hold the power + home + volume up for 4 seconds, the release the power and keep holding the other 3 buttons for another 3 seconds then release, by now it should be in recovery mode, now connect to PC and you should see your phone and all its content.

good question.
he can't do it in two cases:
1- if he is using android 6.0+
2- if he is using a password, PIN or a pattern in his lock screen.
i believe he should have tried your suggestion already, it would be a shame if he didn't because it's an Obvious thing.
however, i should have mentioned that as well...

Not working power button and recovery with "no command." issue

Hi all, have two problems:
1) My power button stopped working long time ago. But it's some mysterious. It doesn't turn off or on screen and it doesn't accept options in bootloader. But it DOES reboot tablet if I hold power button.
I was trying to clean button with alcohol and make it work, but nothing helps. I think that button replacement won't help (I didn't try).
2) I wanted to install new ROM, but I can't. I stopped after flashing recovery, 'cause "No command."-screen appears, where I should use my NOT WORKING power button.
So my questions are:
1)any suggestions about the problem with power button? (Solution of this problem will solve second problem)
2) how to enter custom recovery without using power button if I had "No commans." stock recovery screen?
Thanks a lot!
Type "adb reboot recovery" from inside Android. Same for rebooting to fastboot or bootloader. It's easier, especially on the Pixel 2, than trying to get button presses correct.
If you can hold the button down and reboot it's apparently working physically.

Thanks for quick reply.
Yeah, I enter recovery by "adb reboot recovery", but I have then "No command." screen where I need my power button to skip this screen and enter TWRP.
I've not seen that screen with TWRP, only with the stock recovery.

Interesting. I opened my N7 to check the buttons connector's configuration. Please verify the following:
disconnect the battery and measure pin 1 and 8 with an ohmmeter while pressing the power button - I get <1oHm (short)
reconnect the battery and measure voltage on pin 1 - I get 4.0V
Well?
