Hello, I met a very weird problem of my L720. Let me describe my problem: 1) Phone charges fine when Android is fully boot up; 2) If I keep the charging cable connected, and choose to restart or shut off the phone in Android, it will stuck at the battery icon at the very first boot screen, shown as attached pic, even if I disconnect the charging cable at this moment, phone is still stuck. I have to remove the battery to fully turn off the phone..
Plus, there are two very tiny outputs on the top-left screen saying: "Kernel is not seandroid enforcing. Set warranty bit kernel".
Before the problem appeared, I fully restocked my LL720 to NAE, then used Odin to flash root, then installed GooManger, and TWRP, then installed a customized MIUI.
Does anyone have the same charging problem with me when phone is turned off? Is it a battery physcial issue or related to the ROM I flashed? Your help is appreciated. Thanks.
It is an issue with MIUI actually (the ROM you flashed). Only way to charge is when is powered on and not powered off.

My Galaxy S4 is unable to boot into charge mode (when I plug it in when it is off). It will turn on, but start on the screen displaying the battery icon and never finish booting into charge mode. As a result, it ends up draining the battery and doesn't charge at all.
So, what part of the phone contains the "charge mode"? What do I need to wipe/restore to get it working again? Is something else wrong?
I can post screenshots if needed, but I am doing many tasks at the moment, so I'll only put them up if needed later.

Fixed by re-flashing stock boot loader and image.
My brother just installed CM on his phone. It all worked fine and then a few days later, when restarting the phone, it showed the galaxy s4 logo screen and then a few seconds later it turns off.
Now it won't even turn on. I have to remove the battery and then replace it and then only it turns on. Only to turn off again.
I try to go into recovery or bootloader, but it turns off again. The recover or bootloader screen shows up but then the phone turns off in a few seconds.
Cannot detect on ODIN. When I plug a USB cable in, it won't turn on at all. Even when I replace the battery and try. If I could just connect it through ODIN, I could flash the stock rom and kernel.
There is also an error message on the top left of the screen saying, "Kernel Is Not Seandroid Enforcing, Set Warranty Bit". Is this an issue?
Really need some help. No clue what is going on with this phone...

I guess the error message you was in download mode. Did you tried replacing your battery and then going recovery or download mode?
This is not a software problem.
You have a faulty battery or some other hardware failure.
I will try another battery. My mate has an S4 that works. I will use his battery and see if it is the battery.
I was hoping it wouldn't be the hardware. It is out of warranty now.
Thanks guys.

I can also be a broken power button. Those parts are like € 2 and not that hard to replace.
Hi All,
I am having a similar kind of problem like many others already stated but mine one is a bit unique.
My phone will power on, google logo appears, it starts to boot then nothing happens....it keeps on restarting the sequence but never completes the boot process. I can access fastboot, recovery mode but the phone itself doesn't start.
However if I keep it plugged to my wall charger it completes the boot process and I can access my phone, but if I unplug and start using it just shuts down randomly (1 min-30 min).
I have wiped cache, restored to factory already. Currently I am running 5.1.1 with no modification at all.
Any suggestion to bring it back to life is appreciated.
Replace the battery and I think it will work without any issues.

Most likely the battery is dead.

Hey Guys,
My phone gets stuck in a bootloop if I don't use a charger while turning it on. Actually, doesn't even get past the splash screen and reboots every 1 to 2 seconds. I also need to connect it to the charger to access TWRP. Normally, when I disconnect the charger after the phone has turned on, the phone suddenly turns off. But when I do the same when I'm in TWRP, nothing happens and I can continue using it without any problems. I'll put the logs if you neeed. And yes, I don't need the charger to get into fastboot mode. I'm currently on lineage 15.1 unofficial but the problem persists over other roms too. Please help...
Change the battery
It's the battery , which is under performing with the voltage needed to run the rom process,
That's why you are able to use with charger and got bootloop without charger. In twrp or any recovery mode most of the hardware is disabled and does not need much power.
Telling you with personal experiences

Thanks!! It worked.. I got my battery replaced and not my phone is as good as new ?
I have an S5 with stock Samsung ROM which I rooted some years ago with Magisk and TWRP recovery. For the last few years it has only been used as an alarm clock and I have forgotten how I set it all up in the first place, in fact I had forgotten that I ever rooted it. Up until now it has been working fine but I wanted to give it to my 9 year old daughter to use, so I did a factory reset on it through the normal Android menu. After that the phone works but will only charge in Recovery, not when its off or when its booted normally. Same cable and charger that I have been using up until now and I also tried others but didn't make any difference.
When the phone is off and I plug in the charger,it vibrates, the battery symbol comes up for a second and it displays the message "set warranty bit: kernel" then the screen goes off. The charging LED does not come on. Then after about 10 sec it does the same thing again: vibrate, battery symbol, message, screen off and just keeps going round that loop but never charges. When the phone is booted in normal mode it doesn't seem to detect the charger at all, nothing happens. In Recovery it charges perfectly but its a bit inconvenient!
I tried restoring the last TWRP backup that I had which seemed to contain all the partitions but it hasn't made any difference to the charging problem. It seems the phone has power and CAN charge but is deciding not to. Any ideas please how I can get it back into operation?

Magisk version is old but I have not attempted to update it yet in case that makes the situation worse.

Never mind, I got it working with a different charger. Very strange. The first charger works fine with my Huawei P20, maybe too high power for the S5? Although I thought the device only draws the power it needs even if the charger is capable of more.
