I am trying to unlock the bootloader SM-X200, i have enabled Developer mode enabled OEM unlock and usb debugging in developer mode, but in Download mode do not get warning screen where i should be able to hold volume up button to access. Any help would be gratefully received.

How did you enter download mode? From the recovery menu or by holding the vol up and down and then plugging in the USB cable?
I attempted entered download mode via adb command and then via recovery menu. I only have one hand so kinda hard to enter download via manual method unfortunately.

Yes, it is because that is the only way to get to the unlock screen. And it's not easy to do even with two hands.

Well, my PC is a desktop tower that sits on the floor with USB ports on the front. I'd plug the cable into the tablet and just partially into a USB port on the PC. Then, while holding the up and down buttons with my hand, I'd use my toes to push the cable on the PC the rest of the way in. Just an idea.

So this may have been dumb.. or actually it was very dumb.
But i was using the odin one click downloader, and it got stuck at setting pit file so i figured i'd unplug the phone and pull the battery to reset it. However now it won't turn on
Did i brick it?
Thanks
Probably not. Try using this method to put the device back in Download mode.
Remove the battery, sim card, sdcard if you have one
Insert the battery
Hold both Volume buttons, don't touch the power button
Plug in the USB cable and continue holding both Volume buttons

I have to say.. I LOVE YOU!
Haha, i went to bed with the iphone all setup thinking i would have to use it. Thank you soo much!!
*Edit* I still love you, but do you have any advice on how to get odin one click to recognize it?
The phone goes into download mode now, but the computer says it's an un recognized device so odin doesn't see it
*Edit2* Ahh i got it, What i did was switch USB ports while it was in download mode and somehow that got the computer + odin to recognize it
Thanks again Neurp, you saved me and my phone
Trust samsung device are one of the hardst devices to actually brick, and by bricking i mean black screen, no download mode, no recovery mode, if you can access any of these 2 or your able to see the 'att world phone" screen which is the bootloader, your device IS NOT brick't =], most people tend to get confused with the word "brick" in mobile device
PLEASE HELP ME!
I was trying to flash back to stock but odin3 just sits at factoryfs.rfs
Read a different thread which said that you should unplug and replug into a different USB port. Tried that however got an immediate black screen.
The phone doesnt show the battery symbol when plugged into a charger.
If i can get into download mode I think I can flash stock with Odin3 because I changed the programs privileges to admin and turned compatibility mode on with WinXP SP2
Essentially NOTHING comes up on the screen, regular boot up is out of the question and I cant even get into download or recovery mode. 100% dead regardless of what i do.
I've tried the 3 button download mode trick. I held Volume down / up / POWER before plugging in the USB and Battery....I've tried everything and nothing is getting this thing out of a complete brick.
I've also read that you can make a wire and solder pins 4 and 5 of the micro wire with a 301K ohm resistor in between to simulate the 3 button trick...But im skeptical it'll work at all. (Going to try it soon anyways).
My question is.. What else can I try to get this to Download mode??
PLEASE HELP.
anyone ? any information is appreciated.
I have the same problem just like you.
I am waiting for the solution too.
As I know there was no way now.
u might have to try doing the solderless trick..ill reserach and see what i find though
Give the JIG (301k resistor between pin 4+5) more credit!
Here's a parts list and solderless directors to make a jig:

there are other ways to get into download mode.
Have you tried just holding the up and down volume buttons and then plugging in, or the adb method (adb reboot download)?
I have the exact same problem. my phone came back for a second with portrait mode and usb connectivity. usb worked on my desktop computer, i freaked out and ran to my laptop (that had odin one click, and mod software loaded on it) and plugged it in. while plugging it in to my laptop i noticed a bright blue spark on the usb connector wich i already had plugged into my phone and immediatly lost usb connectivity and went back to being stuck in landscape mode.... i wonder if this has something to do with it?
i had a similar problem and really thought my phone was bricked. I ended up having to use another computer to enter download mode. i installed the drivers first from the odin thread and held the up and down volume keys and plugged in the cable and it came back to life. This was after 24 hours or so of trying every possible combination and getting nothing but a black screen using my original computer.
When I connected the i897 and computer, there was nothing happened. No charging shows. No every modes. the screen have no response.

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.

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
I bought a 5a from the Google Store in the US back in Nov 2021. I have since moved to New Zealand.
So apparently the Pixel 5a was never released here, so support options are extremely limited. Google store support says I'd need to mail the phone back to the US to get warranty service done. I don't think so.
Here's what happened:
Phone was working fine. Was on a phone call. Screen froze. I could hear the person, but they couldn't hear me. I did a hard reset, and the screen went black and never came back on. The phone itself is working-- vibrations, bluetooth devices connecting, etc. But the screen remains black.
I inspected the screen for microfissures, just in case, but didn't see any. Because of how the BSOD happened, it seems very likely it's a software crash that borked my display.
I'd love to do a factory reset, but I cannot access the bootloader because the screen doesn't come on at all.
Is there a way I can access the bootloader via my laptop through USB cable without having to access the screen at all? I never rooted this phone, so I don't have an easy back door entry to the bootloader.
Thanks in advance for your help.
so, this is "funny", cause it just happened to mine, too. were you on the new 13 release? or did you use the app Repainter? cause I don't know what happened with mine. i was rooted, and thought it had something to do with that. first time it happened, i was able to use the flash tool available in the chrome browser. second time, it didn't work (couldn't reboot to fastbootd) and i had to send it in. anyways, not sure if you would have ever enabled usb debugging. enter fastboot by holding power and volume down. then do a flash with the flash tools. not sure if you'd have to wipe your data. google should receive my 5a tomorrow and hopefully they'll give me an update
so i saw 3 more posts on here about the same problem - one of em in the last week. can't be this common of a problem with other devices

Android Flash Tool

yeah, the first time i was able to restore it. you should be able to tell the phone is still connected. connect the usb, hold the power and vol down buttons until you hear or see the alert it's connected. then select it on the the flash tool. choose the build to flash. i left all the options as default, but you probably don't have to relock the bootloader

no you don't. i don't think you have to have been connected to it before. like usually when you use adb, you have to approve it from your phone the first time. but i'm not sure
Just tried this.
At one point in connecting to the Android flash tool, you have to tap on the screen to accept a debugging prompt, which doesn't work as my screen is black.
So how did you get this working?
have to tried powering on with power + vol down to see if you can get to the bootloader?
have to tried to reflash the stock rom? from here https://developers.google.com/android/images#barbet
you must use chrome browser to do this.
you only need bootloader unlocked to reflash the stock rom.

So I'm guessing that I can get into the bootloader to attempt to unlock it, but i can't do anything with it because the screen remains black.
Is there a way that I can bypass the screen on the phone with some sort of tool that will display and let me interact with the phone on my windows laptop? If i can do that, I'll finally be able to do a factory reset without having to reflash anything.

I definitely have USB debugging enabled, but I didn't modify any other settings. It's pretty stock barbet. The problem is with the black screen I can't accept USB debugging on the phone after I initiate a request on the PC.

Does the screen stay black but still accept inputs, or is it completely unresponsive with no display?
Also, the problem with trying to flash a new rom is that:
1) my phone is locked, and I cannot unlock it with a black screen
2) I have to accept something on the screen of the phone (which is black) to allow the flash to initiate

I am 100% sure the phone is operating correctly behind the viel of black screen darkness.
The phone is completely responsive to button presses and paired bluetooth devices. I can tell this because the bluetooth devices tell me that they've connected, and I've also turned on the accessibility (hold vol up and down) so I get voice prompts that tell me the phone is locked, % battery left, charging status, etc. I am sure the phone is accepting inputs from the USB cable when I attempt to flash.
The first barrier is that the phone is locked, and the second barrier is that I can't accept any screen inputs/usb connections with a black screen.
If there were a way to initiate a factory reset only using physical buttons, I think I'd be fine.

so they do make hdmi casts. i had one for my htc one m9. basically it would mirror the screen to my tv by older android connector to hdmi. i am sure they make newer ones that are USB-C to hdmi. it is similar to the one in this video
. except with not being able to use the touch screen as well you would have to use a usb c splitter and then get cheap usb wired mouse to work with it all. not sure if wireless would work. i did use my bluetooth mouse but that was a long time ago on my htc one m9 and once again no touch input leaves you with not many options. it is not a free option. unless you buy it all then return it if it doesn't work or you manage to solve the problem.
you might also want to try the main general q&a forum on xda. https://forum.xda-developers.com/f/general-questions-and-answers.456/ maybe a recognized developer will read it and know of something. the pixel 5a forum isn't most active forum for development.

The problem with AFT is that it requires a screen tap (and an unlocked screen) to accept the USB debugging connection.
