Original Post:
Dear forum,
i flashed LOS on my Samsung galaxy S4 a few months ago, together with TWRP. No problems, only thing i detected is that when i plug the device in when its shut down, the vanilla loading logo pops up for a few secs, then the LOS one shows up and loads normally.
Now I have the following problem:
My phone had low battery, shut itself off, i plugged it in and restarted it immediately. It booted just fine, after a few mins i noticed that the sim card was disconnected, shortly after my phone shut off itself.
Now I can't boot it up into system or TWRP and there is no or just the stock loading screen but stuck at the first frame.
When booting into system, it shows the galaxy s4 front then gets black, and when trying to boot into TWRP it shows the blue loading kernel? logo on top and then shuts off
Pls help as i need my phone ^^
Thank you
Mrluca

[Q] New reboot problem

I'm using the Samsung Galaxy 10.1 Tab (Verizon) SCH-i905
From what I have read, the reboot loop is when the user sees the boot screen, but the tablet keeps on rebooting. My problem is severely worse.
My tablet keeps on reboots, but it doesn't show the boot screen. Instead, it just shows a blank lit up screen.
Not only that, but I cannot always turn on my tablet. I keep trying, but it typically turns on after I keep plugging and unplugging the USB from my outlet to computer, and so forth (for about 10 minutes). When it finally boots, I can go into Odin mode. I flash some sort of firmware to it, and then my device turns off. And I need to keep attempting to turn it on again for 10 minutes before it actually turns on.
Nevertheless, my device still does not work properly. I know this is infact a software problem because my device was working fine yesterday, until I decided to unmount and mount certain things in Recovery mode.
So far, I have flashed recovery.tar.md5 , PDA_SIGNED_P7105.tar, and 75XX_CWM_Recovery_v5.1.2.6.tar. None of these have fixed the problem. How can I return to factory settings?
I just saw the previous thread about this device and am currently installing PDA_HC31_EG0 ... If everything goes right, then there should be no problem. But I highly suspect that the firmware will flash successfully, and then my device will proceed to power off for another 10-15 minutes before turning on again.
If I leave my device plugged into the power source, it will start turning on and off (the blank lit screen) periodically. For example, turns on for 5 seconds, then turns off for 5 seconds (and repeat).
While this is a software problem, it seems to be on the OS level. Are there any other ROM Links besides the ROM in showthread.php?t=1342995 that I should try? Also, is there any other possible alternative?

S3 (I747) Powering off During Boot

Started two days ago. Phone would randomly power off and boot back up. Finally it shut off and would not power back on. I had Cm11 installed with CWM 4.0.4.6. The phone powers on after inserting the battery. The Samsung logo flashes and then it shows the "Galaxy S3" logo with the CM logo below it. The phone the powers off. I have done a factory reset, cleared both caches, formatted the system folder, flashed SlimKat from recovery and tried another known good battery. At this point I figured I would reflash CWM but if I put the phone into download mode, it powers off after just a few seconds as well.
If I boot the phone into CWM, the phone stays on as long as I want it to so it makes me think this might be fixable. Just need some help.
Ask in your device forums.
My apologies. Didnt realize there was another S3 board. Found and posted there.

Nexus 5 stuck at CM logo and also stuck at TWRP logo

I had installed CM13 on my Nexus 5. Everything was working fine. Today I woke up to see Nexus 5 won't even get passed to CM android logo when starting. I then tried to go to boot loader. Hopefully, it opened and I navigated to Recovery and opened. But phone also stuck at TWRP logo. I also noticed when phone starts Google logo takes a little more time to disappear than before. I waited a lot for this but it stuck forever. Actually phone was in charging but battery connector was removed when I saw it in the morning. So it kept rebooting at Google logo. I don't think that could be an issue as it already happened before.
Now all I care about is my data. If I flash TWRP using fastboot, will it work? Will my data be removed? Please reply as soon as possible. I am so concerned about this. Thank you
It might be a little Late but yes you should be able to flash a fresh recovery..without loosing your data

Boot problem - I9300

Hi,
So my S3 stopped working a few weeks ago while I was on holiday. It fell from my hand and turned off on its own. After that I turned it back on and it was working fine for a couple of minutes, then the problem started happening.
Every time I opened an app that used the camera, the phone would reboot. After a couple of reboots, it would get stuck repeating the Samsung logo (haven't been able to boot it since then). When I plug the charger in, it passes the Samsung logo and then stays on the Cyanogen mod logo. I've left it on for hours on the CM logo without any luck. I can't boot into recovery mode because the vol. up button doesn't work, and I can't get adb to find the device on my pc (though it does charge when plugged into the pc).
All I'm wondering is if there's a way I can save my media files from the phone myself, or if I need to take it to a service centre.
Tl;dr - phone loops samsung logo when on battery, gets stuck on cm logo when charging, vol. up broken so can't get into recovery mode, adb won't find the device so no recovery mode like that either, want to save media files.
Any help is appreciated. Thanks

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
