S7 Exynox charging problem when OFF - Samsung Galaxy S7 Questions and Answers

Hi,
already searched and found that I am not alone, but a solution I did not find so far.
I Flashed the Oreo Lineage 15.1 via TWRP.
Before flashing, I did not change anything else, the bootloader is factory-versioni, which probably is from Nougat OS.. So this might be the cause..
Anyway, when plugging the charger when phone is off, I got the battery-symbol with a "flash" sign. If I disconnect, it remains as-is. Have to force reboot by holding the buttons 8 seconds.
Charges normally if kernel is running..
Any idea?
Please help.
Thanks
Joe

My old s4 did this on occasion. I think the fix was to let it charge fully, reboot with usb attached, then pull cord. Next charge power off before connecting usb and should charge normally. One other time I think I had to fix via external SD format then full wipe and reflash rom but that was for force closes I think. Sorry was so long ago now hard to remember!

AOSP ROMs for S7 are bugged and not ready for daily usage in my opinion. Better try stock based ROM like Helios (excellent battery life) or SuperMan (tons of useful tweaks and mods - ROM I personally use and recommend)

If you still want to stay on AOSP download latest build of LOS 15.1 3.3.2018 from changelog: "Fixed charging with device powered off"

Constant rebooting

I have the cricket model. Sometime last night my phone started rebooting on every ROM and kernel. Nothing I do will get it to stop. It doesn't happen in TWRP and that's it. I thought maybe it was a battery issue as I haven't been able to fully charge it because of this issue but that's not helping either. I've been trying to use the upgrade tool but in this state the computer never even recognizes the phone and I can't even get that far, plus it reboots even when in download mode. I'm about to call cricket and see if they can just send me a new one since I've only had it a week but is there anything I can do? Does anyone have a boot IMG for complete stock 60450 ?!? EDIT: Got the tool to recognize phone and start process but what do ya know phone reboots even deep into download mode. It just always wants to restart to the system for some reason, except for when on twrp. UPDATE:EDIT: Turns out the reason the upgrade app wasn't working is because i didn't have enough space for the update to download on the PC . I didn't realize because the app never stated why it was restarting my phone or disconnecting so I just assumed it was related to why my phone kept restarting on all ROMs. Wow lol I feel so damn stupid for not thinking of this 2 days ago. Its installing now and hopefully this fixes my reboot issues. Thanks to everybody here for helping and answering my 1000 question's on every post. Really appreciate it.
it looks like motherboard is gone. I hope you can return it when you have custom rom installed.

I've had the phone for one week lol. Motherboard is gone? Could something be messed up in build prop somewhere? I did try to use a DPI changer app on stock rom once or maybe xposed? I've done a lot of flashing since I got it trying to find the perfect setup. I just noticed that the USB cable it came with is crap so now that I'm using a different one I'm hoping that low discalobrated battery was the issue. Charging it up proper and gonna see what happens after. Also for some strange reason the Flyme OS ROM is the only one that doesent seem to want to restart as often. It still does but it lasts a lot longer before doing so , why idk lol.
turn off the phone, charge it fully and then run the upgrade tool to go back to stock.

I wasnt previously able to corectly charge becauss when i would turn the phone off to charge it wpuld power up instead of gking to the charging acreen. I think the USB cable that came with the phone might have been faulty and I just didn't notice it somehow. Now that I've charged the phone to 50% Flyme is up and running without a reboot, although running quite hot....which could also be the issue. Maybe the metal on the USB tip got toasted. That would explain my reboots in download mode but it doesent explain why the phone never once rebooted on me while in twrp and why it would reboot even while not being charged and had like 30%. Gonna charge it up to 100 and try the tool again.

if you can boot to flyme, and got no reboots in TWRP i suggest you flash from TWRP your previously mad ebackup..if you dont have any, just flash stock kernel or look here in threads, there was a thread and it contains TWRP backup of stock rom..if you find TWRP backup of your STOCK 6045O then flash it from TWRP, and if you dont observe nay reboots, it was due to the kernel. IF it still reboots send it to warranty repair.

Well I'm back on CM now with no reboots. I guess my USB cable just sucked and my battery calibration was off so the battery was showing more than it actually had and probably causing instability. However, I still can't get the tool to work. It just reboots at around 22% exiting me out of download mode. BTW I've searched and scowled almost every thread and I can't find a stock kernel. There's the arde one but I thought that was just his custom kernel for stock. And the twrp back up I definitely can't find. I seen the thread but there was no link.

If it was the USB cable why is mobile upgrade tool rebooting the device at 22%? It makes no sense. It could be the pins on the usb socket on the phone or i dont know.
You should ask someone with the 6045O device to send you the boot.img (aka kernel) of stock 6045O.

Well I first noticed my cable was funky when I loaded up Flyme it kept making an unplug sound and I thought it was just the ROM glitching out but I changed the cable and it stopped. About the tool......I have a Windows tablet that it's only USB connection is one of those mini USB to full adapters and it's a little loose. I have zero problems with it plugging my phone into it for file transfer or for adb, it's all fine there so idk why it would be causing an issue with the tool, last time I tried it k specifically made sure all connections were sturdy and didn't move the whole time and it still rebooted. I noticed somebody in one of the threads said his device did the same thing though and that's why he couldn't use the tool as well......nobody ever replied to him lol
Ahh I spoke to soon. Restored my stock, because that's what I prefer for even at OC it still doesent make the phone nearly as hot as CM ROMs and the restarts came right back even with a decent charged battery. I'm back on CM again though and its not happening. Doesent make much sense because before the restarts were happening across all ROMs. It can't be the kernel in my stock restore as I had used it a bunch of times before with no issues...... Though it is saved on my external SD..... But so is the cm build I'm using. Idk whats going on here. Just wanna return the phone to full stock and call it a day lol. Edit: spoke to soon again lol. There goes CM rebooting, although it took way longer than stock to do so.

My Mi4c only works when charging

After my phone bricked I installed latest Chinese Stable ROM in EDL mode. I chose EDL mode for two reasons (1. I suspected that the phone only works while plugged in to charge and 2. the EDL mode turns off the phone after flashing so I can plug in the charger before booting). Turns out I was right. After the flash was over I tried to boot it without charging it first and it didn't work. After I connected it to the charger it booted normally and the ROM installed successfully.
I tried it again this morning after it fully charged. Few seconds after Ii disconnected it, it turned off. When I tried to turn it back on it was just rebooting to the MI logo screen. I plugged it in the charger and it rebooted 2 times (both times it got to those three dots at the bottom of the screen) and the third time it booted normally.
I also just noticed that the phone is curved a bit (maybe less than 1mm difference between upper left edge and rest of them), maybe from wearing it in tight pockets or something like that.
I think your battery might be dead. Try checking the voltage or the quality.
Replaceable batteries are pretty cheap.
Trimis de pe al meu Mi-4c folosind Tapatalk
Might be faulty battery, might be bad kernel, might be anything. Best way to check is to try to flash latest dev china rom via fastboot, if it still doesn't work try flashing stable 5.1.1 rom, again, via fastboot. If none of the solutions above doesnt work might be bad battery or worse, the controller on mobo died.

Well I hope it's a battery, because I just bought one to replace it. What is that mobo controller? Is it replaceable?
I have the same issue,
Battery replacement and stock rom of android 7 didn't help
I'm afraid is another hardware issue /:
I do have a similar problem, flashed xiaomi.eu and something have been broken.
I dont know how and why but its very strange.
Unplugged from supply i can boot up the phone, can see the miui logo and boot into fastboot but NOT into recovery and not boot up os.
As soon as i plug in supply it works quit normally, can boot up everything seems to be working, booting into twrp and flashing rom. No problem at all.
If i unplug while running os it imediately shut down.
The battery bar inside twrp show strange jumps.
What happens did somehting break ? Id like to gift the phone my mother for christmas.

[Help] Galaxy S7 with Superman Rom only Download mode

Hello XDA Community and stuff,
i have a problem with my S7, which i flashed with Superman Rom a few weeks ago. It worked fine with all its functions, but this morning i woke up with my phone under my pillow. I guess its battery got completly drained out, because it was already low when i fell asleep. i tried charging it, but nothing happens. It also won't boot and the only thing that works, is Download mode. I tried Recovery mode, force reset, safe mode..... nothing works. I'm using TWRP recovery.
I would appreciate, if i could keep my app data, if not then i won't bother, since it can't be helped in my case, if there is no way of doing it without full wipe or anything.
PS: if my english is wrong or at any point not perfect, it may be because i am german.
with kind regards

It worked, but why? it started charging with charging indicator (battery symbol and lightning in the middle with green LED on bottom) after the flash was succesfull. Then i detached it and connected my normal charging cable in wall socket. I had to wait for 1% charge and then i was able to boot normally into my rom. Is there any explanation for that?

Sounds like recovery corrupted, maybe due to the battery running out if it didn't manage to shut itself down in time

OPO keeps turning off unless connected via USB

Hi, 2 days ago my OPO just keeps turning off after a few seconds even when I'm in twrp screen. Even with the wall charger connected, but if I connect it to a computer or any other system it just works fine and normal.
I have lineage 14.1 and I already try factory reset, OS clean installation again and with previous versions. With gapps or without gapps still turning off. Very strange. Can anybody help? I don't know what to do.

Thanks a lot. I will try that. But isn't strange if i connect to the wall charger still turning off? And sometimes it reboots and stucks in Android is starting screen. Is there a way to test the battery? Last week the phone works just fine and the battery lasts the entire day. I just trying to understand what happened. Thanks again,and sorry for my bad english.

Yes,you can order Usb tester and try it,but instead of wasting time over this,just buy a new battery(look up battery thread in accessories for suggestions).
I think this just happen to me.
If not connecting to charger :
-Rebooting itself when flashing rom
-Bootloop after a few second when using the phone (All rom, even after revert back to COS 13)
-Somehow, it not bootlooping if on fastboot.
If connected to charger :
-Phone working as normally.

Custom roms, recovery, magisk

I'd like to generate a thread with tried and tested ROMs, recovery, and root methods like magisk for the Moto G6
I'd especially like to see a working TWRP (official or unofficial), magisk boot img, and any known working custom ROMs
It's all in Guides, News, and Discussions already.
edit: and there's fairly obviously a thread with a working TWRP build in this section. I don't understand what you're asking?

How do you mean bricked? Where is the phone hanging? I assume you already had unlocked your bootloader before attempting rooting/magisk?

Yes i had bootloader unlocked but it still unrooted and its got bricked before i even try for rooting. First of all let me tell u the chronologies. I had this phone from someone in US as a gift but i cant use it on my country(because of network) so i give it a try by unlock the bootlooder, it was succeeded and one day comes update which is april 2018 patch. After the update my phone was unstable, self reboot and bootloops and i found that the screen is flickering sometimes. Then at one night it suddenly turned off when i was sleeping. I tried all method combination button but no luck, it is caused by a bad battery or firmware fail? Please help me!!!
Note: i only got led blinking if i press power plus plugged in charger, the led blinking faster after +20 sec
One single blink every 5 sec and then blinking goes faster after +20 sec for about 5 blinks and repeat to state one single blink. Seems like battery related but i have already open the backcase to see, if i unplugged its battery then push the buttons combination the led is blinking faster like the final state -sorry for bad english

I did nothing except my bootloader is unlocked and do an OTA update (april 2018 if i remember) and its suddenly turn off when i was sleep with state of bootloop days before that. I havent buy any batteries yet because i need to know what is the problem. Yes i've done all of power combination for even 5mnts. It strange because the LED show me different if i press power combination button

For ex : it wont blinking at all if the battery completely empty. Then if i charge for awhile it would blink if i pressed power with vol down (after 20 sec) as i described above. Untill the final state of LED i release power and vol down and immediatly pressed vol up then its LED will keep blinking fast forever as long as the charger is plugged in
My moto g6 also appears to be bricked
I don't want to hijack this thread, but since I'm a new member I can't start a forum thread. Now on to the issue with my g6...
When I plug in my g6 the only thing that happens is a small white led flashes at the top right part of the unit. After about 20 mins or so it stops flashing. Holding down the vol+power buttons to go into recover just cycles the power off and on, with the white led flashing just like before. No recovery screen appears, no android robot; only the blinking white led--the display is otherwise entirely blank & black (meaning not lit at all).
When I connect the g6 to my PC I hear the usual "USB beep" indicating that it's recognized the phone being connected, but it does not show any drive or device either in Device Manager or in Explorer. I'm using Win10, with all the Motorola drivers+software installed.
I rooted the phone some time ago, and the bootloader was unlocked before the phone went dead. The last thing I did with the phone was to flash an Android 9 image from the forum here while the phone was connected to my PC.
https://forum.xda-developers.com/mo...android-aosp-9-0-pie-android-9-0-0r1-t3847354
I had flashed others images with no problems up to that point, even the one linked above. But I re-flashed that image since I wanted to "reset" the image to it's stock point (I had made some settings and added apps I wanted to remove, start clean again). The ONLY thing I did different was that the battery was about 50% so I left the phone charge on one of my PC's USB ports while the image was installing. When I checked the phone the next morning it was dead. Afterwards I let it charge for a week but nothing.
Last but not certainly least, I have also tried two different batteries I ordered from Amazon. No change with either one (blinking white led), despite charging each with the original charger for one week.
Sorry for being so long-winded, but I wanted to give as much detail as possible to see if someone here may have a solution. My guess is that I made an incredibly stupid mistake by letting the phone charge from my PC while flashing/installing the A9 image; I really should have left it on my moto g6 charger.

Don't use anything higher than Magisk 19.3, for some reason higher versions bootloop the phone. After you install Magisk 19.3, you can upgrade normally via Magisk Manager
