Impossible to boot, recovery or download mode - Android Q&A, Help & Troubleshooting

I have an old Samsung Galaxy Young Pro (GT-B5510L).. Everything is stock, it's not even rooted..
It bootloops, so I can't boot to android.. When I try to boot into recovery, phone reboots.. When I try to boot to download mode, I get to the confirmation screen, but it powers off as soon as no key (any) is being pressed..
What can I do to unbrick this device? And if it's not possible, what is the problem?
I think some system file may be corrupt due to use, because it shows the "Samsung" screen (kernel) and the carrier logo (part of /system partition) while booting.. After both screens passed, it reboots

Stuck at Dell Logo Boot Loop

I'm not sure if my phone is bricked now.
At boot up, it just shows the Dell boot logo, and than dissapears and than after a few seconds the dell boot logo reappears. It keeps doing this in an endless loop.
I tried to boot into the recovery menu, but in the general menu it crashed once, and so I tried to reboot the phone, and that's when the Dell boot issue start.
I have clockwork mod recovery and Cyanogen Mod 7.2RC, and the phone had been working great for a month. I'd normally just restore my ROM, but I can't even get into any of the different recovery menus, I can't even get into the fastboot mode, since after the Dell boot logo, it keeps looping back into the dell logo.
I tried with vol up, vol down, up and down, with the phone in vibration mode.
Any ideas? Really like this phone, don't want to have to replace it.
Think there's any cellphone repair stores that could repair such an issue? IS it possible the pre-boot mode is corrupted somehow? Although I would imagine that's boot ROM that's write-protected?
So confused :crying:

[Q] Galaxy S2 Stuck on bootloop

Hi all
I think I soft bricked my galaxy s2. I accidentally formatted /system when I had access to recovery (volume up + home + power). Now when I turn on my phone its stuck on the samsung logo. When I try accessing recovery, the logo disappears for like a second and re appears. I can't access download mode either and my ADB is not recognizing the device anymore.
What should I do?
If it helps, my phone was already rooted, bootlader is unlocked and recovery WAS installed.
Please help

Sounds a bit strange. Formatting system shouldn't wipe the recovery AFAIK.
When you turn phone off and try to boot into recovery(hw buttons), try releasing the buttons just as the samsung boot screen appears and see if that gets you into recovery
Try rebooting into recovery by keeping all 3 buttons pressed until you get there. Do not let go until you are in recovery. That should take a few seconds more. When you are in recovery, just restore your backup.

Stuck in Recovery Bootloop

My phone was rooted and I performed a factory reset and my phone rebooted and now it tries to boot into TWRP but all it does is boot to the TWRP logo screen and then turns black and back into the logo screen. I can't get into the OS or recovery at all.
I did the same thing awhile back. There's a thread on here somewhere which tells you how to fix this.
You'll need to use the terminal emulator in TWRP and enter a couple lines of code. Your phone will then boot normal.

[HELP]Huawei Y635 fastboot&rescue mode loop

Hi,
I have a problem with this huawei Y635, when I power on, the smartphone do always de same loop: Huawei Logo, a blue screen(but during a very few seconds), black screen, and then repeat... Unless I press Volume -, then it starts the FASTBOOT&RESCUE MODE, with the white screen, the android logo and in red letters PHONE Unlocked.
I tried:
1. With an UPDATE.APP, extract the boot, recovery and system .img, and with the fastboot, runing through the windows console, flash the three files and reboot the phone. Conclusion: Again, loop or fastboot&rescue Mode
2. Install the TWRP custom recovery using the Install-Windows.bat. Conclusion: Again, loop or fastboot&rescue mode
3. Download from huawei official website the original software and with the command "fastboot update"update.zip", try to install this official image. Conclusion: Again, loop or fastboot&rescue mode
So, please, I need any kind of help to terminate with the loop, it doesn't matter if I have to install a custom recovery or ROM..... But before install and loose all data, is there any possibility to find the contacts, the media, or any kind of file in the phone storage through the console or fastboot??
Thanks

Can't boot after a random reboot

Can't boot to recovery, os and sometimes to the fastboot.
Latests official lineage os was on it. Nothing was changed I just check the phone and found it trying to boot, now the phone can't even boot to TWRP, it sometimes boots till the decryption stage of the twpr and sometimes just hangs after the twrp splash. I have to recover the data on it.
Any suggestions?
Tried booting alternative recoveries they all don't boot or hang randomly before decryption stage.
Flashed latest firmware using fastboot, did not help.
Fastboot is stable if I could boot to it.
TWRP sometimes boot till the decryption stage and sometimes just freezes on twrp splash. The adb server of twrp is responsive but can't start twrp nor decrypt using twrp commands.
fastboot boot orange_fox_recovery_R11 boot to its splash, r10.1 doesnt boot stuck at fastboot, twrp 3.1 doesnt boot also, stuck at fastboot
sometime twrp boots till the decryption screen but freezes if I click cancel or input the passphrase
Now to phone doesn't even boot to bootloader, doesn't power on, no miui logo and it sometimes blinks red led.
Couldn't solve it, recycled the device.
