Hi,
Last night, I put my S6 onto ultra power saving mode before I went to sleep. All the settings were turned on but when I proceeded to my homescreen, I still had all my third party apps on the screen. The phone then froze and I couldn't navigate across my homescreen and my notification bar was stuck.
I manually restarted my phone and then put it to charge.....but it didn't charge......:crying:
I fiddled around with the USB port, tried a different charger, tried a different phone (and it charged without fail).
For some reason, wireless charging still works which moves me onto the theory of a hardware problem. I also put my phone onto safe mode and it still wouldn't charge, so clearly it wasn't a third party app.
I'm not 100% sure yet, but it appears that my phone might faintly be charging while its turned off.
Does anyone have any theories (and solutions) to my problem. I may end up factory resetting but I'm trying my best to avoid that. I still firmly believe that it is a software bug as the phone froze while I was changing the battery mode and that's when the problem arised.
Many Thanks

Sounds as Hardware Issue for USB Port , ok bro ,
is your phone recognize when you connect it to pc ?
are you tring to use different cable for charge ? may be problem in the cable not the charger .
if you are try another cable and the problem still exist so last hope to make factory reset and see if the problem will solve or not , don't forget to make backup of your data first .
i advice you to go to Techanical Shop and check your usb port .
Hello all
just before i get started i did have a thread here regarding this issue before but sadly unable to find it now so seems i need to start over....
this is more of an update on what has been done so far but will just give detail about the issue from start
when this phone came to me it was not functioning i have no clue to what the wife done to it.... it appears that it may not be charging and something is stopping it from charging..... the charging indicator is on (( orange )) and the battery will display on screen with a lightening bolt in the center.... if i plug into laptop the laptop will sound off the USB connection and disconnection alert will do that 3 or 4 times
pressing power button will make phone vibrate and will display a battery with the lightening bolt assuming that means battery is flat as a pancake
holding volume up and power button brings me into the recovery option total of 3 options show 1) normal 2) fastboot 3) recovery whatever i select say for example recovery it will display the Asus and powered by Android this will last for about 3 to 5 seconds before going off again
so that is the state of the phone as of now and even after other things i have done as i will mention
in the past i have come across 2 phones with the very same issue the first one i flashed my self that phone only shown a charging indicator light but i found the flash tool and rom from the Alcatel website and it fixed the issue so assuming the same would apply with this Asus also the other phone i had with same issue was fixed with a flash
so here is what i have done so far using SP flash tools and following instructions from different places i have successfully flashed over the Stock Rom done it under download only also format + download and even tried firmware upgrade but i am still stuck with the same thing as mentioned above
obviously after flashing the phone it needs to power up to complete the setup process but as is clear i cannot do that if the battery has little to no juice
so what i am looking for is a solution to getting the phone to charge again or a way to charge the battery by other means (( bare in mind this phone has built in battery )) (( battery has been replaced new ))
what could be causing the phone to not charge or at least give battery the power it needs i ask because i do believe the phone is giving the battery some power but very little..... the way i look at this situation is like installing a sound card on a PC but not installing the driver the PC knows the sound card is there but cannot work without the driver same seems to apply with the phone
if i disconnect the battery from the main board the laptop will not pick up the phone even if i press down on the volume down button as i do when using SP flash and the orange charge light flashes so i don't see the issue being with mainboard but more likely a software glitch maybe the MTK chip is not doing its job properly or maybe it thinks the battery has full charge and stops the charger from adding more juice when in fact battery is flat
so can anyone enlighten me to what could be the problem and a solution
thanks in advance
Hey everyone who reads this.
I'd like to start my topic with apologising if I post this in the wrong section.
So, I have a LG Spirit H440N LTE for about 3 years now, maybe a little less. I've always taken good care of it, both physically and in updates / security wise aswell.
My phone has been working flawlessly until the last 2 days. 2 days ago i was charging my phone, and when it vibrated (meaning its 100%) I pulled the cable off, and pressed the power button (power button locks - unlocks the screen) the screen didn't turn on. I was like "wow that's strange" but didn't care much, i just kept pressing the button every 5-6 seconds, nothing.
At that point I pulled the battery out, let it sit for a short time and then put it back, start the phone, I felt the vibration (meaning it's starting up) but no screen, so my first idea was that I need to get a new firmware and completely reinstall my phone, as it seems like it got bricked.. for no reason, by itself ? Strange thing but I accepted it and literally been googling for 9 hours now and I find more and more issues.
After I got LG FlashTool, drivers, and even 3 different firmwares, I wanted to start the phone in download mode to start upgrading, but even though I held down "volume up for 5 seconds and then put the usb cable in" nothing happened, no screen, my PC didn't recognise the phone either.
So I got a little bit mad and pulled the cable out from the phone, I wanted to remove the battery, but out of nowhere the phone suddenly started loading in, screen working completely fine, i could do whatever i want, so my first thing was to do a hard reset. After the hard reset I set up my usual stuff (important apps etc) and I locked the screen so my battery won't go down. Little did I know, I ****ed up again, because ever since that happened, I can't get my screen to work again. I tried everything I could but my PC still doesn't recognise the phone (even after a LOT of drivers being installed), charging the phone doesn't do anything. Regardless if I remove - put back the battery no screen, no screen in download - hard reset mode either, it's just completely black.
I'd like to have some sort of help, because I am just completely out of ideas, I really feel like a firmware change could fix the phone, but if the computer doesn't recognise it, I have no idea what to do.

You might be having hardware issues, such as a faulty power button. If you are the type of user that frequently presses the power button to lock/unlock the screen, this leads to excessive wear on the button components, this is why some users prefer to use the "tap to sleep" and "tap to wake" feature, to avoid wearing the power button out. On my LG, this feature is called "KnockOn", it's located in Accessibility settings.

Hi,
My customer brought me a phone after a water damage. He claimed that the phone has been working fine for a few days after being dropped into the water untill it has discharged. Now when connected to the charger it just normally shows battery percentage level and is charging fine, but if try to turn it on it just shows Samsung Logo, vibrate twice, again vibrate twice and turns off.
What I have done:
- i've fully dissasembled the phone and clean everything with isopropyl alcohol (99%) (most of the water damage was on the bottom panel with usb charging and LCD connector, mainboard and batterry looked untouched)
- i've put both boards for an hour onto the 100 Celsius board
- after another 24 hours i've reassembled the phone and the problem remained
- I've replaced usb charging board and cabel between it and main board with working ones (still the same)
- I've reflashed stock ROM for SM-A515F Poland (without CSC)
- wiped cache
Nothing worked. Moreover, when I tried to enter Safe Mode the screen went "static"? It just looked like analog TV when you have no signal. Every restart ended up with this "static screen". However when i enter the recovery or download mode it looked sometimes fine. After another Stock ROM flash "static screen" has no longer showed up, but the device still "turns off" after Samsung logo and 2x2 vibrates.
Right now I'm not really sure if it is software or a hardware issue. Had anyone dealt with something like this? Any advice is welcome
I haven't tried factory reset yet, because the customer has many important photos on the device (with no backup :/)
Have a good day!
P.S. Tomorrow i will replace LCD to check if it's faulty. If don't I'll be looking a way to retrieve photos from this bricked phone. It's locked with Google Account and PIN, has not enabled debugging or anything else. Is it possible to somehow restore photos from this phone? Some way to install CWM without unlocking BL (to prevent data wiping)? Then from CWM i should be able to fire up ADB and pull personal data? Has someone any idea if it is possible?
Hi again,
I was so happy that i've fixed this smartphone for my customer that i've forgot i've wrote here
Finally I was able to fix the phone. Even the screen looked fine in the download/recovery modes it turned out that it's faulty. With new screen phone is starting fine and everything works correctly. Here's the link where i show the old screen and new one and how the phone responds:
So, first I thought my brother's A51 was water damaged because it was wet a little bit and charging was being interrupted. I left the phone turned off for the night and wanted to look at it again the next morning. The problem is that the screen or something else stopped working.
The screen works fine in Download mode, Recovery mode, or at splash screen with phone's model name, the problem begins when it's booting to Android. It's still stuck at the splash screen. no boot animation, no lock screen visible, just a model name. It's not bricked, because I can still unlock the phone (didn't have a password) and I can hear the unlock sound or charging sound (it started working again).
I tried factory reset through recovery - didn't help, flashing fresh firmware from Frija - didn't help. The only thing that changed is now the splash screen brightness goes down a bit and I noticed that until I am touching the screen so the phone can't lock itself it doesn't turn off the splash screen, but when I press the lock button it turns off the screen and I can't turn it back on, but the phone still works because I can hear charging sounds and it shows up in Device manager.
I also opened it because I wanted to see if there's any water damage, but I didn't see any water marks or burnt components. I cleaned the charging board with alcohol and let it dry but that didn't help.
I'm worried that there's something wrong with the motherboard or the charging board because it has a screen connector.
I can also see that some people here have similar issues:
Unbrick A51 - Stuck on samsung logo
Hi, My phone is stuck on A51 logo for days now it charges - I can enter download mode easily - I can sometimes enter recovery mode some other times it doesn't let me I tried flashing different stock ROMs of android 10, 11 for the phone with...

black screen after splash and unable to factory reset, possibly frp?
Apologies for formatting, typing up on my phone during my break at work. To be more specific, I have a samsung a51 that recently had a black screen of death with no known cause. The samsung splash screen as well as the recovery menus alll work...
forum.xda-developers.com
I should also add that I don't have access to settings so I can't unlock OEM and flash custom recovery / ROM. I also cannot downgrade to Android 10 (duh)
I have exactly the same behaviour here.
I ordered a "defect" A51 on Ebay which was not working. I opened it an saw a water damage at the USB-C charging board. Since there was a lot of oxydated parts I ordered a replacement for this board.
After cleaning an replacing the charging board I have the same issue as szerbi. I see the charging screen (while powered off), I can enter download mode and transfering stock firmware using Odin, I can enter recovery mode. While all these states the display works well and I cannot see any damages like a broken display.
I even got it working correctly after several Odin firmware update and recovery mode / factory reset attempts and I could install some apps and set up my google account. I was very happy. But after some hours again: no screen while Android is running.
Now, when Android is running I hear the charging and the screen shot (pressing volume-down + power buttons) sounds and the phone will be visible as a storage device while connecting to a PC.
Conclusion: The display is black while Android is running. Since it was shortly active I assume either a loose contact on one of the flex cable connetions or a water damage at the displays flex board. Unfortunately latter cannot be checked without dividing the display from the display frame. I assume this is an irreversible process.
