S4 mini GT-I9190 Bootloop

Hi there. Yesterday I got a s4 mini gt-i9190 to see if I could fix a bootloop. The cel turn on, vibrates, displays the phone model and goes no further. Then restarts. Can't enter recovery mode, but can enter download mode, so I tried installing the stock firmware from SamMobile. I've flashed 3 firmwares SamMobile corresponding to Argentina:
I9190UBUBMK2_I9190UUBBMK1
I9190UBUBNA1_I9190PSPBNA2
I9190UBUBNA3_I9190PSPBNA3
and has not been fixed. Still in bootloop. Any idea to solve it? Thank you.

[Q] Galaxy Tab 3 stuck in boot cycle after root

Hi Wonder if anyone can help?
I downloaded mirror beta from the app store to mirror my Galaxy Tab 3 SM-T210 to my apple TV3g.
Once downloaded i was informed that the device had to be rooted, so I used Kingoroot and followed the instructions. Everything was fine during the rooting process and completed informing me that it was successful.
The problem is after this the Tab is stuck in a constant cycle mode of the Samsang GALAXYTAB 3 boot logo.
I have managed to power it off ( Black screen) but have been unsuccessful in getting the device into recovery mode to try an hard reset.
I have tried all the button combinations I could find on Google but it only just shows the galaxy screen. Any help would be much appreciated since it is my daughters tablet and ill be in a valley of it if I cant get it restored.
Thanks in advance

Have you tried to Boot your Tab into Download mode?
If this working , flash Stockrom with Odin.

I'm in a similar situation with the logo boot loop except I am unable to shut it down. I hold the power button for 10 seconds and it reboots right back to the logo again with no shut down. How can I shut this down?

I got in the same situation trying to root my Tab. I wound up holding the power button down a really long time and then gently releasing; then I booted it into recovery and there is an "unbricking your 10.1 " post on XDA that has a stock 4.2.2 link.
Once you get the thing into recovery, and it took several attempts (like for two days)- I had given up and was thinking I had finally truly bricked an android) I got it into recovery and then used Odin to flash the original stock rom and it worked. Then Samsung almost immediately downloaded the OTA and I was at 4.4.2 stock.
The sd card slot is broken, so I am still trying to get the tab rooted, but for now just having it functioning in stock form is better than that Galaxy emblem slowly flashing every 5 seconds until the battery dies (Itried that too, thinking it may somehow recharge and reboot and something would be different-no such luck)
But I found holding the button down persistently made the difference, at least it seemed to.
Good luck

Oneplus 5t Stuck on logo and bootloader is locked (HELP PLEASE)

My one plus 5t is stuck on logo after an official update and the bootloader is locked.
Is there any way to unlock bootloader without access to OS (OEM unlock), so that I can flash any custom recovery?
Or any other solution from experts?

Use fastboot to OEM unlock.
Read up on some tutorials, this one is easy to fix.

I read this but they are saying that you have to go to setting and developer option to enable oem unlock first, but i cant access to my device because my device is stuck on logo screen.

I would suggest you do this first:
https://downloads.oneplus.com/oneplus-5t/oneplus_5t_oxygenos_5.1.1/
Then you should be able to boot to android again. Then tick the OEM lock button

Just enter stock recovery mode and do a wipe factory reset. If it doessnt work, just falsh official oxygen os and do the factory reset again.

If the reset doeesn't work there is a cheat that will work if encrypted and your data is backed up... Open the stock recovery which will require a password. Select the dont remember button at the bottom. It will warn you that procedding will wipe your phone. Do it. The recovery will wipe and reboot your phone with the stock image you just tried to flash. You WILL lose data.
If you cant access the stock recovery or TWRP you can boot either on your PC and perform a wipe from there. You can then move a stock image over to root and flash it with the stock recovery.

I have this same issue, stuck on one plus logo on boot. Can enter fast boot menu but can not enter recovery mode.

Do you still have that problem?

Do a factory reset in stock recovery. If it doesn't work, then use this guide

I am having the same issue. After the android 10 update and after my first restart, it gets stuck on first android boot screen. Not ever the oneplus screen is shows and phone screen becomes dark with led on in grey color. I tried wiping the cache and did a factory reset too but it did not work. Help me what to do. Also where can I find android OS image list of 5T and a process to flash it through PC (ADB commands may be or something else?)

Someone pls help me. My Oneplus 5t stuck in logo screen & not moving to any further screens.
1. Switched Off the phone
2. Now turning it ON & logo screen has come
3. After 5 to 6 seconds logo screen disappears & white LED indication starts glowing.
Pls suggest what to do.

Galaxy A50 Stuck on Boot

here's what happened, the phone started freezing and restarting every 5 mins, I uninstalled some apps thinking that's what's causing it, I used it for around 10 minutes and it was fine, installed the latest security patch update, restarted and everything looked fine.
plugged it in, saw it had restarted again and it was stuck on the Samsung Galaxy A50 secured by Knox screen,
rn: I can't enter recovery mode, (the phone won't shut down and releasing the volume down and holding volume up thing doesn't work)
I can only enter download mode, Connected to Odin, flashed the latest firmware and it passed successfully, but still it gets stuck and won't boot.
any ideas?:crying:

anyone?

Volume up and power doesn't do anything
Volume down + power restarts the phone but it comes to the same samsung black screen

Are you sure you flashed correct firmware? Tried to factory reset in recovery? Full Wipe and then flash the firmware?
You can also try 'adb logcat' to see what the error is if adb is available..

I can't enter recovery mode
Volume down + power restarts but I did try to go to recovery by releasing volume down and pushing volume up the second screen goes black but it's not working
I can only enter download mode when it's connected to pc with odin running
Could it be a hard drive problem?

And I'm pretty sure i got the right firmware

Tbh not sure i got my A50 just recently, didn't even flash anything yet. Is you phone detected when you type "adb devices" in windows cmd?

tried it, it doesn't recognize the phone.

is there anyway to figure out if it's a hardware issue?
cuz I've heard it's a somewhat common problem in the A50 for the hard drive/storage to go corrupt.

I am having a very similar problem to yours, so I will follow this thread. I was using my phone two days ago and it simply turned itself off and since then I am stuck in the logo screen. When the phone is loading I have no indication whatsoever of the battery percentage at all. I still can access option and factory reset and wipe cache (unlike you, apparently - but it does nothing for me). This simply does not help. I end up back at the logo Samsung Galaxy A50 screen. I have downloaded two different firmware... android 9 and 10 from Samsung mobile, and have used Odin to flash it. The process goes through ok and without errors. I get the pass message and the message that the phone is being updated. Then it is time for the logo screen again and form then on the phone simply does not start. I am lost. Can anyone help?

hey there.
apart from the factory reset thing it seems like we have quite the same problem,
at this point I'm afraid it might be hardware thing

You know... I am not really sure. The only different thing I did was to accept to instal a new firmware one or two days prior. I am inclined to think that was it. Anyway... I tried to flash Android 10... Android 9 (both via Odin) and did not work. The support team instructed me to do the hard reset a couple of times ... and wipe cache and nothing. Today I sent my phone to Samsung assistance since it is still under the guarantee because that is what they thought I should do. I'll keep you posted. Hope you can get yours fixed soon.

yh I installed that update too and this happened later the same night.
unfortunately for me all the shops n services are currently shut down because of the Co-Vid situation so i have to wait for now.
thanks for sharing, lemme know what happens.

I've had these same problems before. When flashing with Odin, don't populate the last slot with anything (the HOME_CSC slot). Flash it to the device without auto reboot on, restart the device manually and hold vol up + down to get to blue scrern, then unlock bootloader. Let it restart, then reflash ROM.
