The phone has successfully been flashed with a few different firmwares since the bootloop started occurring. the phone will only power on when the cable is plugged in but it will show the samsung screen and then start the "Installing system update" screen and then instantly go to "No command" and then boot back to the samsung screen to repeat the process. download mode is accessible but i cant get into recovery mode to reset the cache or perform a factory wipe.
The cable is fine and the usb port on the phone let me flash software via odin so i don't understand why it only powers on with a cable plugged in.
Could this be a battery issue? i'm very new to this website and the software end of phone repair stuff so any help is greatly appreciated!
i'm currently running 7.0 firmware G890AUCS7DRF2 from boxwares but the bootloop has been occurring since before i even tried to flash anything.
Also, all of my drivers seem to be up to date so i don't think that's posing any issues.
Thanks so much in advance!
Hi , try to clean the charging port of your phone with 100% alcohol and with clean toothbrush also you can use needle to clean the usb port contact.
Another what you can do is to put your phone into the charger for abot 30 minutes and see if your phone is become to hot on the back side what can be sign of bad charging port or probably dead battery .

I'm havin problems with offline charging after i installed cm11. I've tried change kernel and change rom (i'm using PA rom now) and i'm still with the same problem.
When i plug the charger on my phone while turned off, it shows a battery icon with a question mark on it and i think it's not charging. Is this a general problem or did i make something wrong?
Try keeping it plugged in. See if it charges or not.
Also,did you change your bootlogo?
I didn't change my bootlogo. it boots motorola bootloader and then shows the battery icon with the question mark. I left my phone charging this way for a couple of hours and tried to turn it on. my phone booted with 0% battery and then shutted down, so definitely it is not charging. other thing I notice is that when my phone enter this buggy offline charging mode, I have to press power button + volume down to reboot my phone, it kind of get stuck in this mode when my phone enter it
Try using a different charger.
It doesn't seem to be a common issue.
Can you power up the phone whilst charger connected.?
I've tried two different chargers, one of my Moto X and the original one. If I want to charge the phone I need to turn it on first and then plug the charger. I can't turn it on with the charger on cuz it is stuck on that screen with the battery icon
I'm starting to think I've done something wrong. I did the following to get where I am right now:
I was on stock firmware, so I rooted the phone and installed the newest version of SS. Then I downloaded cm11 and gapps and copied to the phone. I entered the SS and wiped everything. After that I installed cm11 and gapps.
When I discovered that issue I've tried install JBX kernel to fix it and nothing. then I wiped everything again and installed PA rom + gapps and still that issue. Did I do something wrong?
No, you didn't do anything wrong.
Since its persistent across both ROMS, its not a ROM issue either.
In my opinion, its most probably a problem with port or the board. The port doesn't deliver enough power.
You can try flashing the stock ROM back, it might repair in case something s/w related is corrupted. If it doesn't work after that, then its a h/w glitch for sure.
just in case, if I install stock rom and the problem goes away, what might be causing this problem?
I can't re-flash stock rom because I can't charge my phone and I can't boot into the rom or recovery. I don't think fastboot charges my phone. I just realized that bootloader is locked. Maybe this is the problem, isn't it?
it isn't a h/w glitch because before cm11 it was OK to charge offline
You'll need a factory cable to flash in case your phone has insufficient power.
Look for it, there's a guide about making one in the general section I suppose.
No need, I've managed to charge the phone through USB on my pc. When I plug the charger on my phone, that glitch happens, but when I plug the USB on my pc, the phone lights up a white led and apparently it charges the phone (slower, but charges). That's really weird. I really want to know what is happening to my phone
Hi,
about a month ago, I managed to brick my XT910 - I was doing factory reset when I had couple of images installed (using safestrap).
The Battery went dead, as it entered a bootloop which I didn't notice.
I ordered a "Factory Cable", and now I'm able to use AP Fastboot recovery to flash a new image (4.1.2 image). As long as I'm connected with the factory cable to the computer, everything seems OK (flash succeed, I can go and setup the new system, connect to wifi...).
But - the battery never charges. As soon as I take off the factory cable, the phone dies. When I'm connecting regular charger, or regular USB cable to the computer, I get the red circle "M" logo, but it never progress - not booting and not showing the battery image.
Any idea how to solve this?
Thanks,
Ilan
Try keeping it plugged in for a few hours. It should charge.

Have tried, it was connected with both the factory cable and regular charger for few hours each times.
The battery picture (when the phone is off, but connected to power) doesn't even show up.
Any idea if the boot might have been defected? If so - any way to fix it?
I do able to go into fastboot & recovery boot options.
Thanks
Have you tried charging it through your usb port. Using the normal cable.
If nothing else works, Flash the stock ROM using RSDLite. It should fix any issue related to bad flash or anything corrupted.
Yes - tried charging with regular cable from the USB port - nothing comes on in the screen, just the led is glowing white.
I've tried to flash few stock images - 4.0.4 versions I can get flashed, and they run, but the battery icon shows a question mark (and in the system settings-> battery it says unknown).
2.3.6 images do not flash at all (I get failed in RDSlight on the first stage).
Any idea? Is there a boot only file I can flash another way.
Thanks
Hello guys, i come to you with a problem with my phone. I've a Samsung J7 Prime SM-G610M/DS with Stock ROM.
Everything started when a new update came to install like a week ago. It downloaded it correctly and started update process.
In the middle of it, it ran out of battery.. So it began..
1) The phone is practicaly not charging. If i plug it to an USB port or directly to the wall, charges like 6% every 24 hours. Sometimes it doesn't charge at all. Note: whenever i plug it, the battery-charging animation does not work properly. Just turns the battery icon with the lightning in it and then turns off the screen, not showing battery percentage or animation whatsoever. Battery is non removable and tried cleaning charge port.
2) If i put it on Download Mode, computer doesn't recognize it. It is not a drivers issue. I've another Samsung J7 Prime and it connects correctly. I must discard everything Odin-related.
3) In recovery mode, i've emptied cache and did several factory resets with no luck. If i turn it in a regular way, it tries to apply some update but changes to "No command" view.
4) I tried downloading the last stock version and putting it on an SD. Formatted it correctly but when i try to update from SD in recovery, a message comes up: "Couldn't mount /sdcard".
I'm starting to loose my mind here guys.. Please give a hand or a clue!!
Thank you very much.
Hi. I have a problem with a bricked Samsung Galaxy S7, SM-G930F (the Exynos one). A bought it a few years ago and let someone root it to play around with it. I got it back recently and it didn't turn on. I had the battery replaced which allowed me to turn it on, to a "no command" message. I got it into recovery mode. I chose "factory reset" to try to bring it back to a working state. That didn't help, so I booted into download mode and was able to flash the latest firmware; I made sure it was the correct one for this model. It would reboot to a screen with the Android logo and a message of "erasing" with rotating arrows on the Android that stopped after a few seconds. If I left it plugged in, it would stay like that indefinitely. If I unplugged it it would turn off within a few seconds. For a while I could still get it to come up in download mode, but now it does nothing no matter which buttons I press. No lights come on when I plug it into a USB charger, although a wireless charger seems to detect it as the charger's red LED comes on. Following advice on this forum for a bricked S8, I left it not charging for 24 hours to see if it would drain the battery completely, letting me try again. That didn't work; no matter how long I charge it or what buttons I press, nor whether it's plugged into the charger or computer or not, nothing happens. There's no way to tell if it is charging. I have evidence that it works since I was able to flash the firmware and that process went smoothly, but I can't get it back to that mode. Any ideas? Thanks.

Thanks for your reply. I flashed the stock firmware before the phone became unresponsive. Now I can't flash anything since none of the buttons have any effect. and the phone is not recognized by my PC.
@Doctor_Perceptron
If you can't access phone by means of Odin then with 99.9% certainty phone's boot-loader is broken. Put phone into e-waste.
If it was a Qualcomm device I'd be able to help you through EDL flashing. Since it's not I do believe your not able to flash it at this point as already said by the user above my reply
Hello guys,
I really need your help on how to restore Samsung Galaxy Tab S6 Lite (SM-P615), to factory reset after Odin flash failure.
The Odin flashing started, but accidentally my PC ran into blue screen error and restarted. I lunched Odin again and
connected the tablet to the PC again and on the tablet's says; "An error occurred while updating device software". It further
recommended Samsung Smart Switch, which I tried yet it can't even detect the tablet. Odin too can't detect the device,
since the tablet is not able to enter "Download Mode"
Moreover, when I disconnect the tablet USB cable from the PC, the screen goes dark and nothing shows. As soon as I connect
back the USB cable the "An error occurred while updating device software comes on the screen. I used Power button+Volume-
buttons to restart and try Volume+ and Volume- buttons to enter recovery mode but still nothing changes on the screen.
Again on the tablet's screen, there this red writing at upper left corner saying "Voltage Level [2526]. I changed the USB cable
hoping it could have done something but it is still the same issue and same error message on the screen of the tablet.
Please any advice is welcomed, and thank you all.
I would say maybe try to hard reset the motherboard. You can do that by unplugging the battery then plugging it back in internally, but don't take my advice for granted because this worked for me in the past but I am not a tablet or phone guru so I don't know much.
keep in mind I'm very adventurous and that's why I tried the battery thing in the first place.

Okay, I'll try that. However, for mean time before I heed to any hardware possible solution, I want to try with the software base first.
Very much appreciated.
