Stuck on Boot / Logo - Samsung Galaxy A50 Questions & Answers

So last night everything was normal when I just placed my phone on the table and opened an app (Telegram). Soon after it auto rebooted and ever since then it's stuck on the Samsung logo. It resets when I hold down volume down + power, but never progresses. Any thoughts on what I should do next after these steps that I've done / things that happened?
Flashed latest stock fw (SamMobile) for my device - March 2022, CSC Smart, PH - via Odin. I always updated my phone whenever it appeared so it was on the latest already.
First tried HOME_CSC, next did CSC when it didn't work.
Also tried an update one month down to see. Didn't work.
Cannot go into recovery - Waited until battery drained so it can shut down, I plugged it to my PC, held volume up + power until logo showed up many times. Didn't work.
Plugged it into the charger, lightning icon shows but no number. Only happened once and I never saw it again when I tried. When the phone turned off from 0 battery, plugging it into the charger will boot it to the logo again.
There were never any signs of slow down, crashes, reboots before. This was a surprise.
Phone is about 3 years old. Never dropped. Never used for heavy gaming or all day media.
Battery drained faster, but I'm still able to last half a day with normal usage.
Left it running entire night (4+ hours) when I gave up, I noticed some burn in but it faded after I kept rebooting.
I recently tried flashing the earliest Android 11 update but it would fail according to the Download mode screen so I did not continue.
Any ideas? How do I tell if it's a software/firmware issue or if it's already hardware related? If I cannot go into recovery, is that a sign that it's hardware or am I doing it wrong? Thanks.

HTC One X Dead after CM Update

Hey guys,
about 8 or 9 hours ago I updated to 20140209 Nightly via CM Updater.
Everything went fine, phone booted as usual. But then after some minutes of using the phone started lagging got warm around the camera and the screen froze.
After that I pressed and held the power button until the phone rebooted.
Then things went weird. The phone seemed to crash while booting about 3-4 times.
Some times while the CM Boot logo was there, sometimes when the HTC logo what there.
And then the screen went black, Battery LED went off and the phone seems dead.
I cant get it back on. ADB doesn't work. Holding Power Button doesn't work.
And every other button combination (like Power+Vol. Down for 2min) doesn't work.
The phone was plugged into the wall charger for about 7 hours now and still not a single reaction.
Not even the PC gets any connection so its not APX I think.
Is there any way to fix this ?

Seems like the phone is completely dead.
I don't think it's software related.
I cant even boot into bootloader or recovery.
The phone simply doesn't do anything. :/

Note II GT-N7100 Not Turning On at all

Hello Everyone!
First of all, let me say that i'm desperately in need of help with my phone. Here's what happened to it so everyone knows.
My Phone was bought in UAE and was given to me, i live in the Philippines and it was working fine, i can use it on everyday tasks Until, a few days ago my phone performed updates (auto updates) which made it froze, i tried to press and hold the power button but it doesn't turn off. I removed the battery and restarted my phone then all i get is the Boot screen. I went to recovery mode to perform a wipe/factory reset. it returned with a lot of errors about files missing, etc etc...
At that point i thought that my phone might have been updating the OS when it froze so i DLed a stock firmware because i can still go to download mode.
After a day (crappy internet + limited download speed from sammobile) i finished the firmware download then tried going to download mode on my phone but now, my phone doesnt turn on at all. when i press and hold power+down vol+home nothing happens. i tried going back to recovery mode and still nothing happens. Even if i just press the power key nothing happens at all. I tried charging the phone but its not charging as well, The Battery Icon is not showing on the screen anymore but after minutes f charging i can feel my phone getting warmer.
Anyone experienced this issue before or knows how to fix it? i do not believe that the battery died because it was working just a day before.
Any help and TIPS would greatly help.
again: I cannot go to download/recovery mode nor go to the boot screen.
Hello there,
Try to connect your phone to PC and press power button / vol / home button simultaneously, if PC still recognize your phone, then you still got chance to recover it using Octoplus software?

Pixel C powers on and fully charged, but screen completely black

My Pixel C is fully changed but the screen is black and won't display anything at all. I know it is on because I can take screenshots with the hardware button and hear the noise. I can also see it on Android Device Manager. I have long pressed with all the different button combinations. It reboots but the screen shows NOTHING (not even the Google boot logo).
Any ideas would be greatly appreciated!
It is stock and not rooted but subscribed to the Beta channel.
I has this problem today as well and I'm on beta as well. I had to press the volume down button as well as the power button to get into recovery mode and rebooted from there. I can only assume it's something to do with the beta as I have not had this before I updated to O beta.

I didn't elect to install O. I didn't see the update notification in the last couple weeks before it had this problem.
I can't get to recovery because the screen is off. How did you do it? Or were you able to see the screen after holding the volume down button as well as the power button to get into recovery mode?
I had to hold both buttons down for about 30 secs and then I got into recovery mode. From there I just restarted the device.

Thank you for your reply. Unfortunately, that is not working. I have tried holding for 60 seconds just to be sure. It is so strange!
Not sure what it is in that case. Have you tried the volume up button to get fast boot mode?
I am having this problem aswel, on the android O beta. I can not use it and I can not see the bootloader when holding down power + volume down
edit: resolved the issue by trying button combinations until it booted (took around 2 hours total with time of disappointment in between)
edit2: oh my ****ing god it booted correctly (showed bootloader warning + bootlogo + lockscreen) but it locked and now it's black again!
edit3: was able to get into fastboot after 3 tries so i'm flashing the factory image right now (7.1.2)
edit4: flashed 7.1.2 factory image and was able to fastboot boot into twrp but still no display.
edit5: i am now troubleshooting i checked all the files in /sys/devices/50000000.host1x/54400000.dsi/54400000.dsi.0/backlight/lpm102a188a-backlight/ they all indicate 255 which is 100% anyone have any ideas?
final edit: i fixed it by trying a **** ton of times
Hello,
Can you tell what have you do to repair the pixel? Have the same issues after Oreo update :/
Anyone found a way to fix permanently? Mine started doing it around Christmas 2018, and it takes more and more tries every time (to ctrl-down power) and at some point it works... Then all stays fine until I close the lid or put it to seep.
Did someone reinstalled completly the os and got a success? I am not rooted, this started when It tried (and failed) to install 8.1 (update of oreo).

Help! Pixel 3 XL wont turn on after Android Q Beta 6 OTA Update

Hello guys.
I just bought my Pixel 3 XL phone straight from the Google Store and it just arrived two days ago. After learning about Android Q, I opted-in on the android beta and downloaded the Beta 6 OTA update to my phone. The phone downloaded the OTA and installed it and it seems all is well until the moment it rebooted. It didn't turn on again. It won't turn on. I tried to force restart it by pressing the power button 10 seconds, 30 seconds, or even 1 minute+, won't turn on, no haptic feedback, nothing. I even tried the power button + volume down combo. I also tried plugging it to the original charger it came with for 30 minutes, nothing.
Before this, I have experience with flashing stock and custom roms with pixel devices and other brands (I have owned the OG Pixel until it wont boot due to its motherboard issue), and while normally, I could have just unlocked the bootloader and installed the beta firmware thru fastboot/recovery, or even installed a custom recovery, I didn't and instead tried the OTA update thingy (which claimed that you don't have to unlock your phone or anything). I didn't expect that it will brick this early and unexpectedly.
My suspicion would be that the OTA update broke the bootloader itself, or the firmware that loads the bootloader, thus not responding to the power button correctly. It's also not a power problem, because the phone warms up when plugged to the charger. Also, I download and applied the OTA while the phone is charging (around 70%). Could that also be the culprit?
I'm at my wit's end here. I'm thinking I should RMA this phone, which I haven't done before. Are there any similar issues like this before? Did anyone else had similar issues like this one?

Plug the charger in and hold all 3 buttons together, not saying it will work but worth a try, it deletes battery stats and cache, if it does boot then keep hold of them for about 40 secs, hold them for over ten seconds even try for a whole minute, this sounds like hardware fault to me though. Also, if youve just bought it, swap it.

I have tried what you suggested. Still nothing.
If I can I'd try to resolve this without returning the thing but yeah, it may really be a hardware fault. Guess I have to wait for a miracle to happen (like the phone turning on by itself after several hours, like with some posts that I have found around).
If all else fail, maybe I'd just ask Google to replace it.
Thanks anyway :good:
You may want to try to see if you get a USB notification from your computer on Windows and if it does try to flash it Back to stock. Hope it works

Have you tried making an edl cable, to see if the phone boots to qualcomm flash/diagnostic mode. I dont understand why no one in this thread as mentioned EDL mode, its a life saver for when you brick your device. This allows a full factory image flash through qualcomm flash mode. Plenty of tuturials on internet for EDL. (Emergency Download)

Because of warranty?

Galaxy A50 no longer booting.

Good evening All, It's been a long time since I last posted but want to start at custom roms again and I'm hoping someone can help me as I am now considering giving up on this device.
My sister-in-law gave me her old Galaxy A50 after it stopped working, gives the circle with lightning icon but not the normal charge notification. If it boots I just get the Samsung A50 start screen but no boot and no boot animation.
I have cleared cache, factory reset and tried flashing stock roms via Odin as the bootloader is currently locked so no custom ROM's for me to play with yet. I have tried a couple of stock roms but no joy.
The questions I have are below:
1, could a faulty battery cause the phone to not boot?
2, Is there a way to unlock the bootloader via ADB or some other alternative?
3, is there anything I've missed that I could try to get it to boot thus allowing me to perform number 2 from within Android?
Thanks all in advance. :good:
Maybe
No
Try flashing through ordin and see if it gives an error or completes, failing that - try flashing TWRP and see if you can boot into that maybe formatting data or wiping the system somewhere else might help?
Have you tried more than one charger / plug? - same thing? maybe bad wire / plug
I had this issue today and last week. there's a bug w the latest firmwares. havent had this issue on april/may builds.
Anyway my solution is.....
Once plugged in (lightning circle shows up and nothing happens)
press volume down + power till it reboots
once it reboots, boot into recovery by quickly holding vol up + power then release it 2 sec after u see galaxy logo
once in recovery. let it charge for about an hour so it should have enough juice to power on
The thing I notice is the phone does not like to have it's battery drained it this happens most of the time, but this started happening on the last few updates only.
So I will rolllback or install the one ui rom with custom kernel to stop it from happening ever again. it's annoying
hope it helps. it works for my end with the similar locked BL and stuff as u have

Thanks for the reply, I have tried a few different images via Odin but non of them work and I get stuck at the same place. I can't flash TWRP because the bootloader is locked, unless you know a way I can do it with a locked bootloader?

Thanks for your reply, unfortunately it still wont boot. It has charge as unplugged and currently sot on the android recovery screen. If you can think of anything else I could try I would be very grateful
You could try again with recovery mode, as it charges with that mode. I had to repeat the steps I took for a couple of times for it to boot. Or use another cable perhaps? that's what I did too. It's really frustrating.
