How to boot into stock recovery

I'm trying to clear my caches because my battery is doing some funny stuff every since I got the tablet. Just constantly being used up, even over night it drops 25% when I'm not doing anything. I've only downloaded a few apps but it says "Android OS" is what's taking 50% of the battery.
So I get into Recovery by turning off the device, holding power + Vol. down and then I select Recovery mode.
But all I get is an image of the Android with it's belly open and it says "No command."
How do I get to where I can run everything?
Please help!
Thanks!

Is your bootloader unlocked and have you rooted the device yet? The only way I know how to clear the caches through recovery is by doing that first and installing a custom recovery like twrp. If you aren't rooted yet and don't want to root the device I would suggest doing a factory reset first and see if that helps. To do a factory reset go to settings --> backup & reset.

You can do a factory reset like the previous poster mentioned.
If you want to get the stock recovery menu from the android fallen screen, press volUp.

Here is your answer if you cannot get in to the os. The commands will not show up unless you do a two button combo. You can get in to stock recovery by doing the following.
When powered off
Hold power+vol down
When bootloader screen comes up
Use volume down to select recovery and then hit the power button
It will then go in to recovery but only show an android with exclamation point.
From here to see command you have to press power + the middle of the volume button (There is a middle button here) Saw the button in the teardown.
From here you can do a factory reset of the device also.

Yeah this didn't work. I know I got into recovery once without being rooted, but that was on a different device.
I did a factory reset so we'll see if that helps. But it isn't looking like it....
No apps downloaded, only on wifi, brightness is all the way down, turned off location services and the "Android OS" is still taking the battery. It's at 96% after an hour and a half of literally not using it at all...

When you get to the screen with the android and !, press and hold the power button and then press the vol up. No other combination will work. You can not press the buttons at the same time.

Oh boy I need help

My wife's old S3 was given to me to use. I had originally flashed CM 11 on it and tried to upgrade to CM 12.1. In doing so I accidentally forgot to flash GAPPS.
I reverted to the stock ROM via Odin but now I'm stuck in a boot loop. The best part? The device's power button does not work and I cannot make any selections within the stock recovery to clear the cache and reset to factory settings.
Can anyone help me?

Pull the battery to turn off the phone and put it back in. If you feel the phone power up by vibrating upon putting the battery in and not touching the power button and go into loop then you have a bad power button. Do you have this problem? If so, then your only options are repair or remove the power button (there is an alternate way to power the phone up). Let us know if it is a bad power button or not so that hardware issues can be accounted for and go from there.
NOTE: The S3 has been known for some time now to have power buttons that fail. Mine did, and I opt to remove mine as I could not justify paying for a repair when the S3 is my backup phone and test platform and I have a method to power up. I use widgets for controlling power off, restarts, and recovery once powered up.

I no longer have a power button either and recently encountered this same issue after using Odin to flash a stock image.
My solution was to flash TWRP recovery using Odin, which allows one to perform operations using touch instead of the power button.

Bootloops have not been uncommon when reverting from LP to KK. Once you have flashed TWRP as others in the thread have suggested, you will probably need to wipe/ format the internal sdcard. The other remedy some have posted is to load a stock recovery and do a factory reset from within that stock recovery.

Not sure how to get into recovery without a power button.
Is the button loose or not functioning at all? You could try opening the phone and removing everything from the frame and see if the power button functions.

I haven't tried this with my SGS3, but on my Acer tablet I have booted into recovery using adb and fastboot. This requires connection to a computer, but not a power button. Unless you have a touch version of a custom recovery installed you still would not be able to select an item.
You may be able to flash a custom recovery using adb. I had broken my stock recovery on that tablet and used fastboot to reflash a working stock recovery.

Touch screen unresponsive

After upgrading to 6.0.1 via OTA the touch screen does not respond anymore.
The buttons work.
How can I restore back to previous version or do a factory reset? Device is stock/locked.

From what you are saying the power/volume up/down buttons work. So boot into the bootloader mode hold the down volume button in and the while holding this button in press and hold the power button in until it boots into bootloader mode then release both button. At this point you will get android on it side with belly open. Press the volume down button the get to where it says Recovery Mode in the large arrow. Now tap the power button this should put you in recovery mode. After the Google name goes away you will see the android with a red ! point. Press and hold the power button and while doing tap the power Up button. This will bring you to a menu list use the page up/down keys to select the Wipe data/factory reset, then hit power to execute.
The easiest way to roll back would be to visit WugFresh Nexus Root Toolkit web page and use their tool. Link here!
Good luck and report back with results and/or help needed.

Was able to factory reset.
Now I am at the Lang select screen and the touch still not responsive.
Maybe it is hardware issue?

Sounds like a possibility. However, it was working prior to the 6.0.1 upgrade. I would try rolling back to 6.0.0 or even 5.1.1 to see what that does for you.

Installed custom recovery (TWRP) and the touch screen works fine while in recovery mode.
Now I will try to flash a different rom version and see if the touch screen still functions.
Thanks.

After I did Factory Reset via TWRP, the touch screen is like new. I'm good for now.

If I have TWRP recovery and still on stock rom can I flash the SuperSU zip file from recovery to obtain root access ?

From what I've read yes installing SuperSu should allow you to obtain root access, as long as the flash is successful

Broken android when trying to enter recovery

Hi!
Today I unlocked bootloader and installed a custom rom and everything went fine.
Now, when I tried to flash the camera mod app, I couldn't enter TWRP. When trying to do it with the restart option it shows a broken android and I have to remove battery to get the phone running again. Manual (holidng down vol button + power button, as well as holding down buttons and releasing them for 1s) is also not working.
The phone works fine, but I would like to have TWRP working.
Can I just reinstall twrp like the first time?
Thank you

What device? H811? Needs to know more about what software you flashed.
If you can get into fastboot you can push twrp there.

Hmmm i flashed xperia phones locked bootloader twrp on my h818 and i got this error too so it means it changed the recovery but can't start it?

H815 EUR. I installed the 2.8.7.0 and the 2.8.6.1 from https://dl.twrp.me/h815/. I tried it multiple times with these 2 versions and everytime I get the same error.
Connecting it to pc and entering recovery works without a problem, though.
Edit: I flashed Genisys 3.7

So you can get into twrp with "adb reboot recovery"?
Your problem is you can not access it from neither the rebooter app nor the hardware buttons?
When using the harware buttons, hold vol down then press and hold power until the logo shows up. Release power for a second then press and hold again.

Correct, I can get in twrp with "adb reboot recovery"
I was releasing both the volume and power buttons. Tried it again, but I came to a menu where I could only choose whether to delete all data (factory reset) or not. When choosing NO, the phone proceeded to boot normally.

That menu is perfectly normal. You have to select okay. Because you have a custom recovery it will not factory reset your phone but rather boot you into twrp.

Recovery-mode only, is there any hope?

[SOLVED] Download mode can't be removed, I had to try all dat long but I finally could boot into it.
Hi,
So... I had a working Samsung Galaxy S9 (SM-G960F/DS) running Lineage OS yesterday. I noticed something wrong related to the mobile network in my country (FR) and decided to flash the correct stock firmware matching the country code XEF before doing a full LOS reinstall.
Fast-forward 20hrs of download, I perform the flash operation this morning using heimdall(1) and reboot.
Now, the phone bootloops. I can't get into download mode as usual, and the only thing that is available is the stock recovery mode that allows:
apply update from adb
apply update from sdcard
wipe data
wipe cache
mount /system
view logs
run graphics test
I have a working all-countries firmware archive that contains the one that was working previously (minus the mobile network problem). But since I don't have download-mode anymore I can't install it. I tried adb sideload (which is available via the "apply update from adb" option), wipe data/cache to no avail.
Is that hard-brick? Did you ever experience a similar situation? I think there's no way out of this but any advice would be appreciated.
Thanks again!

You should be able to get into Download Mode (Vol Down & Bixby & Power)
Keep trying, try keeping hold of the button combo until after the phone reboots twice hopefully the second time into download mode
Download mode has nothing to do with firmware or recovery that has been flashed, and if you can enter recovery mode, it doesn't sound like a hardware problem either
And use a Windows machine & ODIN 3.13.1 to flash stock

Unfortunately it doesn't seem to work, i tried many tiimes and I usually can do that very easily. It seems flashing the corrupted images wiped it out.

Impossible as it is not part of the firmware, nor can be touched by firmware, it is part of the hardware (Think BIOS vs OS)
You can even 100% wipe all internal storage clean so there is no OS at all and download mode will still work fine
Keep trying

Okay I guess it's possible that the download mode is still there but I can't reach it.
I've been trying hundreds of times every combination I can think of (including Home + Vol Down + Power that used to work).
Any alternative way to trigger the download mode ?

How are you trying Home? There is no physical home button
The button combo is Vol Down & Bixby & Power from a powered off state
Keep a hold of all 3 until it hits the Warning screen, then hit Vol Up to enter Download mode
No other way to access it that I know of, USB Jig hasn't worked since a few models back
Have you tried factory resetting from inside recovery? Unless you used CSC during the stock firmware flash, that could be a reason for the bootloop

I tried factory reset/wipe cache from inside the recovery and yes, I used CSC.

Maybe the issue is with the Volume Down button, does it work inside of recovery for navigating the menu ?
What happens when you try entering Download mode? It just tries to boot as if you didn't press anything?
Only other thing is to hold Volume Down & Bixby, then connect the USB cable to power it on (instead of using the power button)

The volume down button works perfectly in the recovery menu.
When I try entering download mode normally while device is powered down, the phone never turns on.
When I try to hold the buttons during the interval of the boot loop, it goes to recovery (yes, even with volume down, not volume up).
The other technique you mentioned also went to recovery.

BINGO! I kept trying. Did this all day literally hundreds of times.
And it just worked.
I didn't change the way I do it, I think there was some nasty timing going on with the boot loop.
Anyways... lesson learnt: download mode is indeed hardcoded. What a day!
Thanks for being so helpful!
