Hi guys!
I devoted myself a complete evening into fixing my little brothers GS5. 2 weeks ago he told me he was installing an original Samsung update. However after this update his phone would randomly turn off after a few minutes of being on. So I guessed something was wrong with the software. I flashed a stock rom onto the phone, but now it doesn't even boot. I tried multiple stock versions of Android 4x 5x and 6 for the GS5. None of them made the phone boot. Sometimes it showed the Samsung logo, but most often just black screen. I can't boot into recovery either, the same story. I tried twrp, the lights of the buttons were on, but the screen wouldn't turn on. When the phone normally boots with a black screen I sometimes get notifications though. LED flashes sometimes and there's audio.
Anyone having any thoughts how I can fix this? Help is much appreciated!

Hello everyone,
i'm posting on behalf of a friend of mine. He has a i9505 that suddenly stopped working. He told me the phone would randomly shut off completely for no reason. I took a look at it today. On boot the phone would display the kernel logo distorted (vertical lines) and the WHOLE screen would turn green. This happens only sometimes however. After displaying the kernel logo the phone simply shuts off. Even in the recovery it would suddenly reboot. And the a blue led lights up sometimes.
I've never owned a samsung but i have the phone here with me (LG/Sony user ). I went ahead and flashed I9505XXUGNF1_I9505OXAGNF1_I9505XXUGNF1_HOME.tar.md5 in Odin. Flashing went okay, the problem persists.
Btw, knox is 0x1. My friend told me he only did a factory reset, never rooted etc. Can't comment on which version of android he had before.
Can someone help out?
I've been having some problems with my Galaxy S5 recently after ~2 years and some change of owning it. I'm stock rooted on the original ANCG KitKat version.
The problem: If I power off my phone, it will cause it to go into a bootloop, not going past the first screen (Samsung Galaxy S5, powered by android). I haven't found a reliable way to fix it from the loop, but I usually just remove the battery, wait, and try again until somehow it just works and boots up. This is extremely problematic because sometimes my battery runs out and after charging I'll have to go through this game of chance again until my phone works.
The next problem also adds to this frustration as well. When I attempt to pick up a call, my phone will sometimes just not work and restart itself. This leads to lots of confusion and I can't call them back for some time because the phone is stuck in a bootloop.
In the few times that I do get my phone to actually boot up, everything works fine except sometimes my Wifi just doesn't work. It gets stuck on "turning on" where the notification drawer quick setting icon is dim green and never gets to the turned on full green state, eventually just turning itself off (no green color).
I haven't done a factory reset or any real troubleshooting yet, as I'm a bit worried I won't even be able to boot up the phone and I don't have the time yet to spend a full day fixing it. Any help would be appreciated, thanks!
The calling problem may be caused by the google dialer app not being set as the the default phone app but as for the other issues i have no idea a factory reset is a good start though
unfortunately I had the same problem but I have marshmallow but the factory reset helped with the not booting up and see a big difference with the battery
tl;dr at the bottom
Alright so I'm out of ideas on how to fix this phone, couple of days ago my mom came to me complaining that her S5 was giving her trouble. When she handed me the phone, it was in a bootloop of showing the Samsung Galaxy S5 screen, playing the theme and vibrating afterwards then rebooting. I took out the battery and tried to power it on, it ended up successfully booting into android. So from here, I figured there must have been some malware on the device, I downloaded Malwarebytes from the Google Play Store and ran a scan on the device. However in the middle of scanning, the device turned off it's screen and rebooted. (Malwarebytes found 2 malware on the device at that point) So now I'm convinced it's most likely malware and eventually removed all the detected malware on the device. I gave it back to my mom thinking it was fixed.
Moments later she came back saying that it's still giving issues, my first thought "wdf, it was working wasn't it?". I looked at the phone again, and tried to wake up the device using the power button. The 2 soft keys at the bottom lit up however the screen was still black. At this point, the phone was still working fine, the only issue was the screen wouldn't wake up. So I decided to do a battery pull once again to reboot it and it results in the bootloop once again. I did some googling and found various solutions to this, one of them involved wiping the cache from recovery, so it tried it. Booted into recovery and wiped the partition cache (i think that was it), after it wiped and was about to reboot, I noticed a brief "error icon" just before it rebooted. After this point I could not boot into recovery at all (it would just show a black screen and I would assume that the phone turned off) and it was still in a bootloop. It was only after trying to turn on the phone after trying to boot into recovery that the idea of the phone wasn't off and the screen was just black entered my mind. (Because usually if the phone is off, you can turn it on by holding the power button, the phone would not turn on until after a battery pull)
So at this point, it was late at night and I was tired. I left the battery out and just went to bed. The next day I tried to turn it on again and to my surprise it booted up fine but I was skeptical. I had a theory that the device would work fine as long as the screen remained on, so I set the screen timeout to 10 minutes and kept it on for probably 30 minutes while I continued to google. Since it stayed working during that period of time, I thought perhaps locking the device triggers the issue. I turned of "Power Button instantly locks device" and proceeded to turn off the screen using the power button. When I tried to turn it on, it was back to the same problem (black screen, device is working fine, soft keys lit up). I did a battery pull once again in an attempt to reboot and now it was back to problem #2 (boot loop, can't enter recovery). At this point in time, I considered doing a factory reset but since I couldn't enter recovery, I'd most likely have to re-flash the stock firmware.
Since I didn't have much experience flashing android devices (I personally only flashed 2 or 3 devices ever, all of them were successful but I still didn't really trust myself), I had it sent to a local cellphone company and had them try to fix it. Eventually I got the device back, but they were unable to fix the problem (they tried to flash a stock and custom rom). Now I'm back to square 1, the phone is still in a bootloop, no sound, no vibration this time, I don't have much experience with phones since I've only owned 2 in my life. The phone seems to be soft bricked pretty good, I've still got 1 more trick to try (full stock firmware flash) before I call it quits, any ideas?
tl;dr
- device is stuck in a bootloop (issue 1)
- i was able to enter recovery mode once, now it's not accessible
- download mode is accessible
- the device has been able to boot successfully a couple times, but then it has another issue.
- device's screen would not wake up after turning off, softkeys still worked, everything else still worked. (issue 2)
- the device was sent to a local phone repair company to fix (unsuccessful)
- currently device is stuck on issue 1
additional notes
- device has not been dropped or wet
- device has been owned for more than a year without problems
- this problem was recent (3 days)
- no sd card
- dark screen was turned off
theories
- screen could be malfunctioning or defective somehow, but then if it can show the bootscreen and download mode screen fine it seems unlikely also since it's been working fine for over a year
- it's a software issue of some sort, but has already been flashed by local phone repair to no success, then again I'm assuming they just did a basic recovery flash and called it quits
So, I know this phone is old asf but I can't find any tutorial and I really don't want to flash my phone for the 30th time again.
I just tried installing LastPass Authenticator (for 2FA), and when I launched it my phone just turned off, I tried booting it up and it went past the splash screen to the T-Mobile logo, and after that just shut off.
Now it'll just stay on the Splash screen for a bit, it won't even get to the "Samsung" animation, and just shuts off. It was stock ROM as well as stock recovery as well.
Don't know why this is happening, but its the second time something similar has happened. I really don't want to reset the phone due to the data I have on here, so any help is appreciated.
Hi all!!
Unfortunately my first post here starts with something not quite fun.
My BS2 has just randomly decided to go into a bootloop (I think it's called.). It doesn't even get past the logo screen and it's totally unresponsive to all buttons. So, not quite sure what to call this.
I have NOT EVER rooted my device or flashed any firmware or messed with it in any way.
I was just using it normally when it suddenly started flashing and turned off, never to turn on again.
The phone is running the latest version of the Global from. Nothing else to describe really except that the phone is bone stock with nothing ever done to it.
Would really appreciate any insight anyone would have on this!
Same problem
