Bootloop - can't enter on recovery mode - Galaxy S3 Neo Q&A, Help & Troubleshooting

Hi everybody !
I have a SAMSUNG Galaxy S3 NEO in hands with a bootloop problem.
Since the moment I put the battery to the phone, it automatically starts and be in continuous bootloop. I've tried to enter on "Boot Recovery" (Power + Volume Up) and also in "Download mode" (Power + Volume Down), but both without success. It starts the recovery mode, but then automatically reset the phone again....
Trying to connect the phone to my computer, as it is in bootloop, it doesn't appears as a connected device on computer...
Any ideas how can I solve the problem?
Thanks in advance !

Recovery mode is with "Power + Vol Up + Home" and download mode is "Power + Vol Down + Home".
You were missing the home button on both, that's way it was failing

Maybe it's a hardware problem. Perhaps the power button is stuck?

Galaxy S4 (i9505) boot problem

Hello,
I create a new thread because all "hard/soft bricked" topic are not the same as me.
I explain, my sister give me a galaxy S4 (i9505 variant) who has fell into the water, the eMMC seems corrupted.
The phone has "boot order" problem:
- If i try to boot normaly (just pressing power button), the phone boot in recovery mode
- If i try to boot while pressing vol down + home + power, the phone boot in "normal mode" (android seem not damaged)
- If i try to boot while pressing vol up + home + power, i show the "samsung galaxy s4" splash screen and the phone reboot in recovery mode
The only way for me to start in download mode is to boot android (using vol down + home + power) and using ADB with "adb reboot download".
I've tryed to flash pit, rom (who is stock rom i9505XXUHOF2) and trying "bootloader update" option of odin, nothing change, the "boot order" is always wrong !
I'm not sure, so i think it's Qualcomm firmware who manage the "boot order", if yes, how can i redefine it?
If no, do you have some informations/solution that can help me to have the phone working "normaly"?
Thank you in advance for your reply.

Try this: uncheck everything in Odin except f.reset time, flash stock rom, remove USB cable from the phone, remove battery, wait 5 seconds, replace battery, boot into recovery, perform factory wipe, remove battery, try to get into download mode again.
Do the volume buttons work when the phone has booted into android?
Hi audit13,
Thx for your reply
I've tryed what you suggest so boot order is always wrong.
Volume buttons work fine (i need them to boot android).
The problem isn't to get the download mode, so key combinaison to boot method, before phone feel water, keys combinaison was:
power button => boot android
vol down + home + power => download mode
vol up + home + power => recovery mode
And after feel the water:
Power button => recovery mode
Vol down + home + power => android boot
Vol down + vol up => download mode
If it can help, while phone is shutdown and charging, the phone vibrate every 3 seconds and didn't charge, if i just press vol+ and vol- keys during 2~3 seconds, the battery logo appear and the phone start to charge. A second thing i've see, when i'm on android, if i use the "reboot" function, the phone reboot in recovery mode.
It seem that the bootloader didn't boot on the good partition.
I've see an option in odin v3.10.7 called "auto start" and can take value from 1 to 8 (or nothing), do you think this can be a setting that allow user to define the partition number used to start?

Here’s how to enter Safe Mode on a Galaxy S10 smartphone:
Shut down your Galaxy S10 smartphone
Hold the Power button key and release it when the SAMSUNG logo appears on the display
Right afterward, press and hold the Volume Down button
Hold the Volume Down button until the device boots up, and the Safe Mode text appears in the bottom left corner

Put it in download mode. Hold bixby, volume up and power, plug in type c connector, and then usb to pc. You should be in download mode now

M30s Bootloop flashed Twrp with auto reboot checked🥲

Hi, I have m30s and like any other samsung phones I started getting automatic restart problems. I read from this, and thought may be custom os, Kerel may solve the issue.
Hence I tried to flash Twrp from here. I forgot to uncheck auto reboot while flashing using odin. Got PASS in odin and phone restarted only to get stuck in Bootloop. Can't enter download mode too.
Vol up + vol down - no action
Vol up + power - no action
Power + vol down - reboots and gets in bootloop
Did I brick my phone?
Help me please
When your phone is currently able to only restart by pressing Power & Vol- then do following:
Release buttons for restart when the screen goes black. Immediately push Vol+ & Vol- and insert with PC connected USB Cable.

Fix bootloop Galaxy Tab A 10.1 [SM-T510]

Hi, my device is boot-looping forever. I cannot enter recovery (I have TWRP installed). I cannot even switch it off.
What I have tried:
- normal switch off through power button (device is not switching off). It always restarts itself
- reboot to recovery (Power + Vol Up)
- reboot to bootloader (Power + Vol Down)
- force hard reset (Power + Vol Down for 7 seconds, then Power + Volume Up)
None is working.
Can I enter the recovery, maybe issuing some commands from a computer?
Any other option I could try?
Thanks!

No, the PC won't help. The trick is to hold power and vol down and as soon as the screen blanks, switch from VOL down to up, while keeping power button pressed. You have to be quick when switching or it will just bootloop again. And the cable shouldn't be plugged in.
Thanks, this helped. I recovered from the bootloop.
Hi, I'm stuck in bootloop too. The fix above isn't working for me. Could somebody discribe the process a bit differently please? Maybe I'm doing it wrong? What exactly is the time to switch from volume down to up?
My bootloop shows the Samsung logo then a warning about unlocked bootloader with prompt to press power and then the Samsung bootlogo again. Inbetween the screen turns of for a few seconds.
I was able to go to download mode by connecting the tablet to my pc and pressing vol + and - at the same time. Then I installed the nexus rom by Magendanz. Made a factory reset and format data in twrp. Everything is fine now.
