Now first of all, this isn't my main phone (wasn't even mine), but i still want to see if i can get it working to tinker with it.
So basically, when i try to turn the phone on it gets stuck on the "Samsung Galaxy A50" screen and doesn't get any further than that. Booting into recovery mode works... sometimes? and going into download mode only seems to work by going to recovery first.
Oddly though, the power (and volume?) buttons only seems to work when the phone is plugged in. If it's not, it doesn't respond to any button pressed at all. (The battery isn't dead, i left it on a charger for 7 hours and no change)
I've tried:
Factory resetting through recovery
Flashing stock firmware through odin (success, but doesn't do anything it seems)
Flashing a custom recovery (doesn't succeed because bootloader is locked)
Letting it die completely and then charging it
Charging it for a while
The bootloader is locked, and this was not the result of a failed flash. Because of this i feel like the chance of recovering this are pretty slim.
Does anyone have any ideas on what i could do?

My Sprint Galaxy Nexus recently got submerged in saltwater (it was in a drybag that failed). After lots of rinsing and drying, I finally got it to turn on with the Google logo and go into a boot loop. I held vol up/down/power to get to recovery mode once and decided to do some Googling to make sure how to proceed. Ever since then, the vol up/down/power mode doesn't even work. Trying that, the phone will start up and just go to a black screen (if I'm in a dark room, I can see that the display is on, just black). As opposed to just hitting power which still shows the Google logo and boot loops.
I also can't seem to connect to adb, although I've done that many times in the past. I suspect it's because I can't get to bootloader mode. If I could get to that, I think I'd be golden. It seems, the only thing I can get to is odin mode, so I tried returning to stock using that. I was unfamiliar with that process, so I walked through the guide here and used the FH05 tar, however, it always seemed to error on the radio-cdma.img. If I remove that from the tar, it'll write fine, but nothing really changed in terms of what I could do. I was unable to find any other working tar links.
Any ideas on what to try with ODIN or help getting my adb connected or getting to recovery mode?
I was messing around with my phone and entered recovery mode (PhilZ Touch) and I kept tapping the empty part of the screen. Then the screen turned off, but on again after a few seconds. Then the phone wouldn't boot past recovery mode. I was stuck!
I researched the problem online and found another forum that posted a flashable "fix". So, I flashed it and then to my horror, realized that the zip was meant for a completely different phone!
Now my phone won't display anything on the screen, won't enter into Bootloader/Download Mode nor Recovery. I can't even do a Cold Reboot!
When I plug the phone into my computer though, Windows makes the USB connected dinging sound and attempts to install drivers but fails. In Device Manager, there is now a QHSUSB_DLOAD entry that appears and disappears depending on whether my phone is plugged in or not.
Does anyone know how to fix this and get the phone up and running again?
Preferably ASAP!? I literally have no phone... not even a landline!
Bro am in tha same boat...am about to send mines off to mobiletechvideos and they'll fix it for 50$ thats the only option ppl been saying...i tried the other way but its a headace and it dosent work for me ...
I ended up solving my problem, but not in the way I wanted. Since my phone was 100% dead, I went back to ATT since it was still under warranty. I told them a story about how the phone had been malfunctioning lately and then just completely died. They replaced the phone under warranty, so now I have a brand new one.
There definitely doesn't seem to be any easy way out of this problem once it strikes. I still don't know what happened to make the phone unable to boot out of recovery, even after wiping stuff, factory reseting, and reflashing roms. All I do know is that I have never had a problem with PhilZ until I started to rapidly tap the blank part of the screen (I like how it vibrates... I'm weird like that). This caused the recovery to never want to exit. Every time I reboot the phone, it automatically went to recovery, even after a full power off or battery pull.
Nevertheless, I am still going to root and mod my phone... just carefully.
You have a hard brick, which is nearly impossible to fix.

If any one can help with any idea I would really appreciate it.
So I let my little brother play my s2 and he completely ran the battery out.
now I have left it on the charger over night, when i go to boot into recovery. You feel the phone vibrate then see the samsung for a split second, and if you keep holding the power you just feel the phone keep vibrating. The screen never turns back on. Now I know it works because i was able to boot recovery once, when i did that i just tried a full wipe and reboot. phone kept boot looping, so i pulled battery, but now i cant get into download mode or recovery.
Please help, or atleast let me know that its not fixable
thanks
You are supposed to let go of power after the first vibration. ?
Try downloading a stock ROM (.tar format, I believe) and flashing it, using ODIN. That worked for me when I bricked my SGH-T989.
I later had to install a new recovery, but you can play around and see what needs doing.
Didn't find anything similar on here so I had to post. My T999 no longer boots except for a vibrate when the battery is removed and re-inserted. Occasionally it will get to the CM boot logo and then the screen goes off. If I time the button presses right, I get to the Download screen but before I can hit the Up button to confirm download mode the screen shuts off. This happened all of a sudden yesterday, the last activity being to shut off the Alarm. Tried charging but it will not get past the initial battery icon before the screen goes off. Tried replacing the battery but that didn't help. I also tried to follow the debrick instructions but it didn't help. I was running Vanir AOSP 4.4.4 with no issues until yesterday. The device does not register when connected to the PC using USB and the charger LED does not light up when plugged into charger/PC. My feeling is that something went wrong with the boot but I am unable to get into any usable screen to do anything. I had managed to brick a Samsung Vibrant before but I didn't have to struggle as much to debrick and ODIN back to stock. Any help would be greatly appreciated, I'm now without a phone .
Mine is also acting like that. It wont boot to any rom even stock ones. But i noticed that if i connect my charger it will boot to the homescreen. Sounds like a battery issue right? I also thought that but when i go to recovery, it did not shutdown after leaving it for a couple of minutes. I'm also baffled why it wont boot. I'll try to borrow other battery to test if it still the same.

Remove battery snd put back in. Does the device try to turn on by itself? If so you probably have a bad power button.

Boot download mode and flash stock or root66 firmware with Odin. (You may need to factory reset too)

Done this using root66 but still the same. Now my phone went to worse. It wont get past the S3 logo in the boot screen and just shuts down followed by a vibrate. But if i connect my charger, it will continue and run as normal. My suspect might be a bad battery but the thing is it doesn't auto shutdown when is download mode or in recovery mode. Will try to borrow other battery and update if this fixes the problem.
This is pretty strange. Woke up to my phone with the Galaxy s3 boot logo. And it wouldn't go past it. Tried flashing different backups I had but none of them let me go past the boot logo. Flashed CM10 since my version of TWRP recovery is so old that it can't flash anything higher up, and it goes past the boot logo finally after 2 hours then goes to the cyanogen boot logo but doesn't go past that. I'm going to try with ODIN tonight.
Seems very strange that there are others that had this happen to them to. My phone has never done this before, and it happened randomly.
What does it mean if my phone doesn't boot past the logo with an odin to root66 file?
Edit: Nevermind seems to have worked... for now.
Edit 2: Okay so now it's stuck in an infinite loop where it boots past the logo, shows the android mascot then does an android is upgrading app 1 of 169 then goes back all over again. This is fun! Can anyone help?
Edit 3: Okay so I had to do a factory reset. Got it working now. Starting to get sick of the things I have to do to get updated firmware. Samsung needs to get their crap together!

Hopefully its just the battery.
Download mode may work because of how the battery reports to the os. If its going bad and reporting incorrectly that its low, it may trigger a shutdown. Whereas in download mode the os isn't running so its not reading the battery info the same way. Just a guess.

Just for future reference, factory resetting solves about 98% of boot hangs.
Still for both of you, id take this as a sign that you should make sure your backups are up to date. If something is failing you'll be glad you did!

Yeah factory reset unfortunately didn't work for me when I needed it before I had to ODIN to root66. But I was able to do a nandroid after I couldn't get it to boot and extract my sms from Titanium backup. What an awesome app, super thankful to that dev for making it.

Turns out it was the battery sir. I've tested it with another battery from 2 different phones and it worked fine. While the phone i tested with the defective battery didn't event get passed the samsung logo. I've suspected it might be having the low voltage causing the phone to shut down.
Anyways, after that i bought a new battery immediately and everything seems ok. thanks for the reply doc.

I can confirm that it is likely a bad power button, I have tried everything including dismantling it and seeing if I could dislodge any dirt that may be causing the problem but it didn't work. Looks like I have to find a local repair shop or ebay to get it resolved. Anyone recommend a good place to get this fixed. Funds are limited
Im not sure exactly how difficult the repair is most people seem so do it themselves and have given indications that its pretty easy. You can find the part online for a few bucks.
Help! I just got this phone and wanted to root it, so started flashing using Odin, couldn't flash because it turned out I had a slightly different firmware causing the phone to be stuck in a boot loop, with download mode and recovery mode still accesible.
Now that I have the right firmware, I can't actually flash it because the battery seems to have died during the boot loop while I was downloading the right files.
It has been on the charger for about 45 minutes now and nothing changes, no response on buttons, no battery indicator, nothing.
Would be really glad with any tips to at least get it to charge so I can boot to download mode and flash?
Also, trying to root probably triggered the knox bit, so that means all waranty is void right?
Edit: it seems to be in EDL-mode, any tips on what to do to restore the phone?
Did you solve your problem ?
Let charge your phone at least for an hour from an electrical outlet (not from computer).
