Galaxy S6 not charging and bootloop - Galaxy S6 Q&A, Help & Troubleshooting

Yesterday my friend's S6 (international model) stopped charging and the screen says " Power sharing . The power sharing cable ..." ( view image 1)
then when the battery became 0 the phone turned off. I plugged in the charger (original charger and working perfectly on other phones) but it seems like the phone is not charging . it only shows the following screen (view image 2) for some seconds and the charging led is not turning on.
After leaving the charger plugged in for 10 min, I tried to boot up the phone. It booted but unfortunately it was a bootloop only showing the screen of " Samsung galaxy S6 "
So I booted into recovery and did a wipe cache and wipe data/factory reset but unfortunately the bootloop problem persists.
I would appreciate any help.

EDIT : In recovery there's a yello phrase @ the bottom of the screen
dm-verify verification failed

Maybe try with a different cable and charger and see if the problem persists ? If you can charge the phone charge it to 100% and then flash the stock firmware via ODIN.

I've got the same problem as OP described for the last few days, but without the bootloop issue.. I even got the same Power Sharing message. Tried charging it with the original fast charger and cable as well as with another micro-usb cable connected to the pc, with the phone off and on, but my phone won't charge .
I think the micro-usb port of the S6 might be broken because when i move the cable a bit up and down and keep it at a certain angle stable, the led starts lighting up for a moment and it charges, but loses connection sometimes .
I thought sending it back to my retailer or samsung but my knox is tripped . Has anyone tried sending their phone back with the warranty void and could still get a new device or is this nearly impossible?

Xperia Z3 unable to charge - able to connect in flash mode - backup possible? wipe?

The problem:
My Z3 isn't charging at all, it's showing the charging screen and the red led is glowing for a few seconds, then it's turning off, showing the charging screen and the red led for a few seconds, turning off and repeats that without actually charging the phone. I can't turn it on, but I am able to get into flashmode by holding down the volume button and connecting it to my pc.
I already flashed the stock image. It's rooted and was running the latest official image. Locked Bootloader.
A few days ago it started changing the battery status every few minutes. Going from 12 to 50%, staying on it for a few minutes, going back to 20, to 6, just random numbers.
I used it today when it suddenly powered off. Despite being charged for one and a half hour in my car with the dock connector. Since then I am not able to turn it on or charge it.
What I already did:
Testing multiple chargers and cables, incl dock connector.
Tried to backup it with adb console, however it can't connect to my device. But I have zero experience with ADB, so I tried the flash tool from androxyde. It's connecting in flashmode and I was able to flash a stock image.
Am I able to backup the phone from the flashmode?
If not, am I able to wipe it so the service isn't able to view my personal data?
I hope somebody can help me :crying:
I was able to charge the phone now, I used both, the dock connector AND the USB connector cable. I don't know if it's damaging the battery but it seems to be broken anyway. Still giving out random numbers (was normal until it went past 10%, now it's jumping between 50% and the real number.
Sad thing is, I wiped all the data on the phone. Good thing is, if it wouldn't have turned on, nobody would be able to see my personal data.
It's time to give it to a service point I guess. I hope I get a new phone btw, seemed to have a faulty antenna as well the last weeks.

OnePlus One Charging and USB Issue

Hey guys, so I have a small problem. I used a Mi Bank (5200mAh) power bank to charge my OPO yesterday. It worked the day before. When I plugged it in yesterday, it charged for like 5 seconds and then wouldn't charge. So I tried a variety of other cables and chargers but none of them worked.
I turned the phone off and plugged it to charge, the charging battery icon would appear, disappear and then the phone would reboot to the charging screen and the cycle continued.
I then let the battery die and did a few power cycles and plugged the phone to charge while it was off. It started to charge and then fully charged. I used the phone till today and wanted to plug it in again. I charged it for around 20 minutes and it worked.
Now, I'm facing the same issue as yesterday.
Phone won't charge
Does not get detected in MTP or ADB mode, but DOES get detected in Fastboot mode.
Ampere shows the voltage as 3.7v, I recall the voltage being around 3.9-4.1v)
OTG also works. I connected a flash drive and it detected the source and I even watched a movie.
When I boot into recovery (TWRP 3.0.2.0) with the battery dead, and connected to the charger, the phone stays ON. I did a full Nandroid backup and a wipe and flashed another ROM as well and the phone stayed on, but as soon as the phone rebooted into the ROM and got to the boot animation, the phone shut down saying "battery low"
Not sure if it was a placebo effect or not, so I wrapped the phone in a dry towel and left it under my pillow for like 30 minutes and then plugged it to charge. It began to charge and after a full charge, I could use the phone without an issue so I proceeded to backup my data to the PC just in case I needed to perform a full wipe. About halfway through the copy process, the indicator light went off and the copy process got cancelled and the phone wouldn't show up in the PC again.
My question is, What is the culprit here?
Do I have to replace the entire motherboard?
Is it just a battery issue?
Is it a USB connector issue?
Any help with regard to this would be much appreciated

I've got this one plus 1 (stock operating system, unrooted and locked) and he wont charge at all (when he off or on), my charger and cable are original and they do charge other one plus one (I've got 2 of them).

[Q] Reviving the (possibly) dead battery

Hey guys,
I've got a Google Pixel phone today and it's having a major problem. Battery won't charge, at all. Here's what I did:
1. Checked and cleaned the USB-C port
2. Checked with 2 chargers (A normal USB 2.0 type charger and a LG G6 fast charger)
3. Tested it with 2 USB-C cables. One is from the LG G6, the other one is the original that came with the phone.
4. Tried charging it using the laptop USB ports (3.0)
5. Ran a battery tester which said the battery was alright (an apk)
Android version running: 8.1.0 with Feb. security patch
The seller also said that the microphone and possibly the loudspeaker don't work. I would love to charge the phone and try the Android P BETA program on it, see if it solves anything.
I've ordered a new battery from Sweden (possibly not original, but I've read that it's alright)
Any tips?
Thanks!
Edit: The phone indicates that the battery is charging (both when it's shutdown and plugged in). The battery is at 1% now and the phone shuts down immediately - won't power-up at all.
I have a similar issue with a Pixel I bought refurbished (might just return it) - but the battery won't charge past 75%; got up to 84% one time, though. Even plugged in, once the battery gets to its 'max', the percentage will actually go down a little, to around 70% (if it stays plugged in at >70% then it usually goes down, with screen off). I also noticed mine doesn't seem to charge at all when powered off (probably a big warning sign) and also sometimes won't charge until booted up and unlocked (sucks to pick up your phone that's been plugged in a couple hours to see 4% battery with the charging indicator on the status bar says the phone is charging....).
It WILL charge if it gets booted into (TWRP) recovery - so, if your phone stays on while connected to laptop, try booting into bootloader and fastboot boot twrp-latest.img (easy to find thread for that, or just go TWRP.me website and find it there).
If that doesn't work (locked bootloader, etc.), try charging it while in the stock recovery, but I don't think it'll give you an indicator. If all those fail to give it a charge try charging inside bootloader, plug and unplug a few times, make sure USB connectors are clean. Good luck with the replacement battery, screen/digitizer can easily get messed up during dissasembly...
Edit: noticed you said won't power on at all, if you can't even get to bootloader (vol down+power with phone off) then battery or USB assembly is probably no good. Does LED flash red on the top of phone?

Hey, thanks for the tips.
I unfortunately tried all of that before it wouldn't boot up anymore, so no luck there. Also, no indicator at the top, battery is probably alright, might be a software issue or something, but can't tell since I can't update it to Android P or atleast downgrade it. I guess I'll have to wait for the battery to arrive and then try it like that. Hopefully that works.

Help getting S7 out of recovery loop?

There's a lot of aspects to this problem at this point, I'll try to be detailed.
I was recently given a bricked Verizon S7 (SM-G930V) to work on (full stock rom). The battery is completely dead, and when plugging it in to a high power charger it shows the recovery booting screen for 1-2 seconds, then black screen, then recovery booting again. So the recovery seems to be broken, and its putting it into a bootloop. From what I've been able to find over the last few days I believe it was caused by either a bad ota update, or it loosing power in the process of updating.
Im able to get it into download mode, but the recovery seems to be completely broken. I've left it on a charger overnight four times (combos of plugged in, on a pad, in download mode, and looping) and it hasn't charged at all.
When its on a high power charger I'm able to get it into download mode, but it dies as soon as i try to swap it to my pc. I have a high power official samsung wireless charging pad, but when its only on the pad its completely unresponsive. If I plug it into the charger and have it on the pad at the same time, im able to get it into download mode and switch it and get it to show up in odin.
I've tried flashing the latest verizon branded firmware, as well as the unlocked firmware (with various combinations of odin versions and settings) and I either end up with an error on the phone (odin/firmware too old) or it just completely fails and the phone turns off. Even when deselecting auto reboot in odin, after a failed attempt (complete(write) operation failed at various points) it reboots.
Only thing I can think of is that the charge pad + usb combo isnt providing enough power with a completely dead battery, but I don't have a working S7 to swap the battery into to charge it, and when its looping or in download mode its not charging at all.
Any ideas?
