[Q] Galaxy 5.0 Stupid Question

My 5.0 player is in Android system recovery mode and I am just trying to wipe data /factory reset. I can scroll down using the vol keys but I can not select the option. When I try to select the option by pressing the power button nothing happens. I know this seems really lame but it is driving me crazy. Please help.
Does the CWM menu just disappear? If so, I've had that problem a few times. Just reboot (forcibly) and try again.

When I press the power button nothing happens. If I hold it down it shuts down. When restarted it goes right back to system recovery menu.

stock recovery uses the home button not the power button for select.
Update: also newer versions of CWM (vers 5.x.x) can use both power button and home button.

Ok so has it just stopped working or have you added or taken something away if you have it rooted then you might have a brick if you havent messed with the system then you hold all buttons down together to do a hard reset for 3mins+ if you have rooted and messed with it you need to flash the latest safe ota zip youll find in stifliz posts

SONY XPERIA Tablet S - Factory / Hard reset
There are two ways to perform Factory Reset:
Metod 1:
Open "Settings", tap "Backup & reset", "Factory data reset"
The tablet will restart automatically.
Metod 2:
Power of the tablet. Pres and hold the Power On key and the Volume Up key at the same time.
When you see the Sony logo release the Power On button but continue to press the Volume Up button.
Now you are in the Android recovery menu.
Use Volume keys to scroll and the Power On key to select.
From the options select:
"Reset to Factory Settings" and "Yes - erase all user data".
The tablet will restart alone.

Weird. Every Galaxy Tab 3 I've played with, when you get to that screen, the reboot and factory reset options are at the top. Sometime you have to play with the Volume buttons to get the options to show up on some devices. Like the 2 volume keys together, or just kind of play around with various buttons. That's certainly the right mode, because Vol Down + Power would be the Download mode. My experience has been like this: https://www.youtube.com/watch?v=nft8HVUc5Y4 - but that was on the 210 / 211.
But if you can still boot into the OS, the factory reset option is in the Settings > Backup and Restore.
pls check this link.It worked for me

Samsung galaxy s3 GT-i9300 cant access the recovery mode nor the factory reset mode.

My samsung galaxy cant access the recovery nor the factory reset mode. I just replaced the screen and i need to reset it since i forgot the password i was using way months back. i tried the combo keys. volume up+home key plus power key. It just reboots normally. i try to make an emergency call and the volume keys are all working.
Is home button works? On my s3 it's hard to press correctly home button. When i want to go into recovery i press it as much as i can. Mostly I go into recovery with reboot options but when my phone is in bootloop I must go into recovery with combo

HELP! Blue Wave 8 33GT tablet stuck in recovery mode with "No command" message

HELP! Blue Wave 8 33GT tablet stuck in recovery mode with "No command" message
I got my Blue Wave 8 33GT (not HD+) tablet completely bricked. First of all, I know this is not really a popular device and some of you might not have a single knowledge about this one, but I hope in any way you might help me get this device working again. Thank you in advance!
Some info about this device:
Bluewave's website: Wave 8
Android OS version: 4.4 KitKat
Device processor: Rockchip-based (RK31)
What just happened? It suddenly reboots while I'm playing and gone into recovery mode with an Android and a "No command." message. Now it won't boot the system anymore whenever I reboot, it always going into this recovery mode.
It has no volume buttons, just a reset, a hard back button and power button. Holding down the power and back button goes into the recovery mode directly. Through normal boot, it flashes the Bluewave logo twice then goes into the recovery. While the reset button immediately turn the device off. There's nothing else I can think of that I can do in this case.
My laptop can recognize it as an ADB Device in recovery mode and I think I may be able to flash it via Rockchip BatchTool, but the instructions I've read states that the device should be up and with a USB debugging enabled which I am not currently able to do in recovery mode. Device is rooted and working totally fine until this happened.
Anyone got into this kind of problem and able to go through it? Please, any help is greatly appreciated.
P.S
Just let me know if there are any additional info I could give you.

Hey! Thanks for your reply and time.
I tried every combination of either of the two keys but there is no such recovery menu showing up, and I am pretty sure that this device doesn't have a built-in recovery for factory reset.
If only I could go to its download mode stuff to be able to flash the firmware...

"Long press the power button to restart the device. If restarting fails, hard reset the tablet by poking the Reset hole using a pin. " it is from FAQ
maybe this could help.
1. Press the power button to get the option menu for
Power off
Reboot
Silence phone option.
2. on that menu you have to hold down that power off option on your touch screen while also holding down the home push button on the side of your tablet.
3. This brings up a screen to reboot into safe mode..(these are the 3 steps the company does not tell you that is why no one gets it to work.
4. HIt yes for safe mode and then hold down your power and home buttons on side of tablet till the dopo Logo appears.
5. Release both buttons and hit the power button one time and then hold only the home button down till a menu option appears.
6. Use the home button to move down to factory reset and press the power button to select. Once it says complete then use the power button to select reboot.
Problem solved. Hope this will help everyone out.
The only way is to remove the battery, attached again the battery then power it on their is no hard reset on blue wave the go to settings factory reset
