[Q] Galaxy S2 will not power on

Hey all,
My Galaxy S2 won't turn on, I have tried a soft and hard reset, I have tried to boot into recovery and into download mode, I have removed the battery for 30 mins and tried again, I have tried another battery. The phone seems to be on as the battery/top of the phone is still warm, any ideas?

S6 Edge G925F gets stuck on Samsung logo.

Hey,
I bought my S6 edge by pre-oredering from Vodafone in Qatar during April. I then shifted to India for university and went back to Qatar during December during vacations. During that time, when my phone was charging, it just switched off. When I started it again, the phone was stuck on the Samsung logo. I then restarted it by pressing Volume down+Power button but it kept happening. Then, I let it stay at the Samsung logo for half an hour and then restarted again. This time it started working.
But this problem would continue everytime I charge my phone. It would randomly start working sometimes when I restart but most of the times it would just get stuck. Now it's always stuck and I don't know what to do. Please help.
My LED light still flashes when the phone's stuck. And I haven't rooted my phone (just downloaded an app called root browser). I have done a factory reset and wiped the cache partition but it didn't solve the issue.

Galaxy Tab 4 T230NU in strange bootloop

Hi, I have a Tab 4 and it is in a bootloop, but the strange thing is that it actualy pass the logo an boot animation, when it reaches the welcome screen to setup the tablet, the tablet restats itself.
Once I actualy was able to pass the configutarion and use the tablet, but when i did a factory restore the table start with the bootloop again.
I have tried reinstaling two versions of the room with odin and all went ok but the tablet iss still on bootloop., and I havent been able to pass the welcom screen bucause it keeps restarting, also if I force the shutdown holding the power button the Tab turn on by itself until the battery die.

Samsung Galaxy S4 WEIRD Problems (A must read for certified problem solvers)

Ok, so one night I was using my phone normally (Browsing. Watching YouTube, Playing Games) like everyone else does. Then all of a sudden it shuts off, but immediately turns on again without me pressing a button. (So basically it suddenly auto restarts on its own) This occured maybe 2-4 times (all in one night) until one time, it shuts off but doesn't turn on again (basically an automatic shutdown), so I tried turning it on again (Power button), then I got shocked because all of a sudden it enters a boot loop (Screen displaying this sequence : Samsung Galaxy S4 screen, my carrier logo screen, The encrypted screen (where you have to enter your encryption password) then again the Samsung logo but this time with the colors splashing from the background, then it shuts off again.) Sometimes after the boot loop sequence, it vibrates but never turns on again, sometimes it just turns off after the sequence. And as I try and try to get away from the boot loop, the sequence became shorter. So I'm guessing it's a battery problem, BUT my battery isn't bloated or deformed. I tried clearing the cache first, again the sequence got shorter (never going up to the carrier logo screen), then I tried formatting the data, still to no avail. Now, when I turn it on, It shows the Samsung logo screen for 2 seconds and shuts down.
I tried flashing it with ODIN thru Download mode BUT (HERE'S where another problem occured) :
My phone never get pass on the system.img.ext4 dialogue and my screen just goes blank. But ODIN still recognizes my phone. And when I remove the USB cable, ODIN says FAIL.
I'm sure the cable is working. I downloaded the firmware for my carrier (Tre 3).
What could be the real problem here?
Here is the description of my device :
Samsung Galaxy GT-I9505
Bought from Italy, Tre 3 carrier
Can I download a different region/carrier for my I9505 phone?
Advanced thanks for anyone who comments and I'm very sorry for my English. Thanks!
I would install TWRP recovery, boot to it, and use it to format data, which will remove the encryption. Then I would either push a rom to the phone via recovery or try to reinstall the stock firmware with Odin. Make sure that you run Odin as admin as well. The firmware must be the same version or newer. If you still have the stock recovery and can boot to it, then I think the build number of the currently installed firmware will be visible there. You should be able to use that to Google the correct version you need.
Hey it's me. Just posting a quick reply.
Thanks for replying to my post. Yesterday I successfully flash a rom to my GT-I9505 (Version 5.0.1 Italy HUI 3G). However it still didn't boot up. At first try it booted up to the first setup screen then just randomly shuts down. Then as I try to boot it up again, It just shuts down after the first Samsung logo (with the GT-I9505 logo), I can't boot into recovery cause it shuts down. I'm sure it's not a battery issue cause when I boot into download mode, it can stay in that screen for like 10 minutes. What could be the issue? I'm planning to disassemble my S4 sooner to see if something's wrong inside. Thanks again for the reply

Click to expand...
Click to collapse
After you flash stock firmware, the first boot can take 15-30 minutes so leave it a little while
