Factory reset if you hold it for 25 seconds.
There's also code in the bootloader which makes it appear you could boot from a USB rather than the internal storage by holding down the button (but the bootimg on the USB would need to be signed by goog).

Using your computer and usb cable, remove the battery from the phone. Plug the pc side of the cable into your pc. Put the battery back in the phone. Hold the volume up and volume down buttons. While holding the buttons, plug in the phone side of the usb cable and continue holding. You should be in download mode within a few moments. View my clip for a how-to video session on this...
Reply if this worked. It SHOULD work as you have soft bricked and this is a way of entering download mode during a soft brick of the phone.

Did you try the volume button method with plugging in the USB cable into the phone while it's plugged into the computer? It sounds like you are just doing the volume buttons plus power button method. The JiG is for HARD bricks which doesn't sound like it's what you have. Although it will work for SOFT bricks also.

First post, been lurking a while though. I actually had the same problem, and fixed it this way last night. Took me about 30 tries and lots of sweat before I figured it out though

how long did you hold the buttons up and down after you connected the cable? iv held it for 2 mins and nothing!
Ugh. This is the way to do the button combo:
Step 1 remove the battery, open odin3 the one click jh6.
Step 2 plug in the usb and hold the volume up, volume down, and power.buttons.
Step 3 put in the battery and release the power button but keep holding the volume up/down buttons.
Step 4 press download. This puts the phone in download mode. I found this method when I had a soft brick. Umyou don't need a jig since you can still boot to the white screen. This will work.

I will try this method, as I am in the same boat as the others here. I have already placed my order for the USB Jig but am hoping that this method will work.
However, under step 4, you indicate that you "press download." What do you mean by this? Where is the "download" button? On odin3, the only buttons I saw were start and master clear. Is the download button an option on the Captivate?
To my knowledge, there is no "Download" button on ODIN or a Captivate in a semi-bricked state.
Edit:
If those directions don't work, you might also try a method I've had success with.
1. Remove battery, SIM card, and MicroSD (if you have one) from the phone
2. Wait at least 10 seconds with the phone having no power source
3. Hold Vol Up/Down, don't let go
4. Insert battery
5. If it worked, in a few seconds you should see Download Mode

I think Im really screwed I have done everything that has been posted previosly and nothing seem to work. as soon I connect to my computer odin3 dose not do anything it's as though nothing is connected and my phone goes to that empty battery with the frozen loading star or what ever its called, it also does that when I connect it to the AC outlet.
Still waiting on the jig to arrive I think thats my last hope!
Why doesn't anyone use adb to get into download? The only time you HAVE use the 3 button is if you get phone!Pc screen. If your phone can get to the att screen, open command prompt, change directory to adb tools location, and type adb reboot download. Do all this before you hook your phone up to the computer. When you're ready connect phone to pc, turn it on, right after you see the att splash screen and hear that your phone is connected press enter.

Help , Broke captivate screen

Hi there
I broke screen on my captivate (cm-10.1.2 ; usb debug mode was off)
I NEED the data that is on my phone.
I think the best way is to mount usb drive via recovery (clockworkmod)
I don't really remember menu items...
please someone (with same CM) tell me the key sequence how to get to - usb mount
like:
volume up + volume down + power (10 sec)
volume down x 5
Power
and so on.....
Please help.... I am in real need

Hey,
So if I'm understanding your post correctly,
Step 1: hold power button down until you feel the device vibrate twice.
Step 2: hold volume up+power for a few seconds (since your screen is broken, I'd hold it for like 5-10 seconds just to be sure)
Step 3: now, I counted the amount of times I pressed the volume down button and it was six until I got to MOUNTS AND STORAGE, but I'm on a galaxy s3 using the most recent CWM and it doesn't say specifically "USB MOUNT" but it does say MOUNT SD which is the same thing you're looking for. So I'm going to guess they are probably in the same spot.
Step 4: press volume down three time and hit the power button and that should get you mounted.
I'm going to apologize in advance if that doesn't work considering we are on two different devices but I ran captivate for two years and the muscle memory seems right to me.
If that doesn't work, couldn't you just connect your phone via USB to your computer? Doesn't that pull up all your files?
Anyways, good luck man.

Question Recovery Hell

My friend has an S21 Ultra 5G with the Exynos SoC. There's an app that constantly crashes, Samsung Audio Remote, that he NEEDS to control the volume on his sound bar because he's handicapped and can not use a physical remote. After a total of 3 HOURS on the phone with Samsung support, the next step and alleged solution is to wipe the cache partition. But I can not get I to recovery. The procedure support told me to use, that I tried 3 times while they were on the phone, did not work. Now, I'm no tech god, but I have successfully flashed dozens of roms on several devices over the years, including 4 Samsung Galaxy devices, so I know a thing or two about pressing buttons in the right sequence. But, this S21 is kicking my tail. It's sooooo much is a trainwreck that I have decided that Samsung does NOT want my money, so I'll be happy to never give them a penny more. But. My friend has this $1000 turd so he's got to get it figured out. So. Please. How do I get into recovery so I can wipe the cache partition on this pile of junk?
Build number is G998BXXU2AUBB.
As a side, this problem exists on his S21, my Moto G Stylus, and his Galaxy Tab tablet, but it does NOT exist on his LG Stylo 3, so I'm pretty confident that even wiping the recovery partition will not solve the problem, but if you've ever dealt with tech support, you know that until you do the next useless troubleshooting step, they won't move on to try to actually solve the issue. So, I gotta do it.
Turn off the device.
Then boot with both the power button and the volume up button pressed (and hold them) until the phone boots to recovery.

In my experience this only works if the phone is turned off and connected by a USB-cable to a computer. If it doesn't sense the cable connected it will just boot to normal Android OS.

It's funny that several websites forget to mention this, they just write about the key combination and rebooting, but without the cable being connected to the PC it won't boot to recovery.
on most devices you dont actually need the cable connected first and some devices do weird stuff like turn on when you plug them in. They probably dont have the actual device.

You needs to connect to PC to reboot to recovery along with combo key started from Android R on Samsung devices. On older os it doesn't requires

I tried that and it didn't work for me, I actually needed to boot into a PC, or maybe it doesn't work with simple slow charge USB? I will play with this to see if it works with another power source.

Sorry to correct you, but it's power and volume UP ! not down! Of course what's important is to have the phone connected via USB cable to a PC, or pen drive, power bank etc, otherwise it will just boot to normal Android OS.

Not necessarily, any USB-C to USB-A cable should work. Make sure the phone is completely switched off. You need to press vol up+power for some time until the Samsung splash screen changes to the recovery mode.

Is this of any help:
Have you enabled developer mode and you have it set up for USB debugging already? If so you can use the ADB command line to restart your phone by issuing the following from a command prompt in the directory you installed ADB/Fastboot or anywhere if you put them in your path variable -- "ADB reboot recovery"
If you're not having any luck with that, you may need to reset (NOT factory reset, that will wipe everything) press and hold the volume down key and the bixby/power key and hold them for a 15 second count, even when the device powers off. This combination will power it off no matter what. After the slow count of 15, release the keys, plug in your USB cable, and press and hold power/volume up key as the previous posters instructed you - until the phone starts and you see the logo - this should boot you into recovery mode as well.
Is your phone booting into the system? If so, a 3rd option you may avail yourself of is an restarting app for non-rooted devices such as Shutdown, there are several, read the descriptions and pick your poison from the Google play store (If you're running a stock device make sure the app you choose doesn't require root) it will however, require you to grant accessibility permissions - full control of device and SHUTDOWN in order to function - and that will give you the option to reboot to recovery mode.
Good Luck, L4XS

Question Clearing cache partition

I cannot boot in to recovery mode. Volume up & power key won't work (cable is not helping). Any idea?
Timing is everything. Relax... I hit reboot and once the screen flashes off hold the volume up button until the menu comes up.
Won't work. I did try this so many times.
Try this:
Power down the smartphone.
Then wait a few seconds for it to completely shut down. ...
Now press and hold the Power and Volume Up buttons at the same time.
And continue holding these two buttons down even after the Galaxy S21 starts to boot back up.
Not working... I don't know what is wrong.

Unplug the cable if you haven't.
Did you toggle on Developer options?
Try turn it off.
Turned developer options off still no luck. Weird.
If your timing is off with the button push it will do that. Sometimes it takes one time, sometimes 2 or 3. Don't power off; hit restart. Before it starts to boot have the volume up button depressed.
LADB is so much easier for stuff like this if unrooted. once setup properly, just issue out
Code:
reboot recovery
I gave up. I am going to shi...y Samsung Store tomorrow to do this. It is unbelievable. All my browsers lags and I cannot simply clear a cache. Every day I am regretting swap from 1+8 pro. I thought Samsung changed since I had s8 but no - it is even more laggy, bloated. They do and sell the best hardware but simply have no clue about software optimisation. Thanks all for help

I couldn't get it to work either, until I had the usb cable connected to my laptop - then it was able to boot in to recovery mode and let me clear the cache.
I tried it just with the cable in the phone, the cable in the charger and the phone, no cable and the only way it worked was with the cable connected to laptop and phone with the laptop powered on.

Try this:
Power down the smartphone.
Connect the phone with PC or laptop via USB cable OR while your phone is closed connect a type c USB memory stick.
Now press first Volume Up button and then the Power button (don't leave the Volume Up button)
And continue holding these two buttons down even after the Galaxy S21 starts to boot up.
