Hi,
I've been having issues with my unit (6/128gb) for the past month, and for the life of me I cannot figure it out. My phone reboots multiple times when fast/turbo charging, sometimes even when I'm charging it with my PC. I did not damage my USB port nor the original cable.
I've swapped multiple ROMs, AOSP and MUIU, still no changes. Different charging bricks, and cables (Samsung original and few cheaper) - no changes.
What I have noticed is that if I keep the display on, it will not reboot. I've even made a python script to write down the battery temperature each minute (thought there might be a spike), and if the script is running, then the phone will not reboot, even pushing the maximum 33W and display off.
Also, my PC does not recognize the phone, displays an error, and the phone reboots even if I try charging it while off and while in fastboot.
Does anybody have any suggestions? I thought even swapping the USB board, but I do not think it is the culprit.

Without knowing what it was, I encountered the RLOD on my phone after leaving it on USB overnight. After reading the first two or three pages of two different threads I tried the little lucky "fixes" and found that none of them worked.
I have a backup phone and need my phone for work, so I put my SIM in that phone only to find it was dead. Went to my local AT&T store and they said the SIM is fried. They replaced the SIM and everything is working now.
I replaced the battery in my TyTN and now I'm recharging my original battery. The phone works without problems, or heating up, or shortened battery life.
So here is my theory:
The phone has a similar monitor as the offgrid solar system does. It's job is two-fold: don't let the battery overcharge -and- don't let the battery every discharge to 0.
I suspect that most problems may happen when the phone is connected to a laptop or desktop computer via the USB port and left on when the computer goes to sleep. At this point, the scenario is similar to a monitor on an offgrid solar home. The monitor decides when to pull from the batteries and when to fire up a generator. But if the monitor is set incorrectly, it constantly flicks between charge/generator and the end result is a huge draw on the batteries (rather than a charge going into the battery).
Now with the laptop asleep the trickle charge is way lower than normal. Activity on the phone may also actually flick the laptop in and out of sleep mode. The basic end result is the phone starts the same type of draw between battery and trickle charge, causing a higher than normal draw on batteries, and finally it heats up the chip on the SIM and fries it either partially or completely.
If you have "resuscitated" your phone, but still have problems, simply replacing the SIM should fix it. If you get the RLOD I'd say get the SIM replaced as it is fried. Once you get the SIM and any SDHC card out, very tentatively try to recharge the old battery on the wall charger. (In other words, don't take your hand off the charger when you plug it into the wall) If you get a yellow light, breath easy. If you get the red light, UNPLUG IMMEDIATELY and throw that battery away!
My research on offgrid solar has been going on for almost a year and I began this theory when I noticed a few things:
1) I saw posts from people with not just HTC phones getting a red light.
2) I saw a few posts where people mentioned they used the USB overnight.
3) I have seen firsthand what the constant toggling can do to a 24V 1500 kilowatt hour battery system and the heat it generates.
Except...
There is no USB power when a laptop is shut down except for a few newer models which are designed intentionally to do so. And USB activity does not wake the laptop, particularly not "in and out" of sleep mode. If it does, your laptop has problems.
Final point.. Hasn't it been ground in to use the supplied charger? Most people who report failures admit they were using third-party chargers.
That said, a USB cable should be a more reliable charge source than a cheap AC charger due to the fact that a laptop has to have clean power itself and cheap AC chargers can fail in many fashions and often result in excessive DC voltage or AC voltage winding up in the source.
Shortly: I flashed a new rom (not so new... Mameli 2.0 with WM6.1) and the upgrade process stuck on 99%, computer saying "All Done"
No so... trying to reboot the Wizard gets up the bootloader screen... no problem, will you say BUT... I was in a hurry so I leave the USB cable connected and go away for a few hours (I suppose the USB cable may keep powered the device but now I guess no... )
So, when I came back, the Wizard was turned off.
First try was soft resetting the device with no success: screen remains black.
Then I try to connect the power supply and nothing happened...
Then I pull off the battery and keep it off for a few seconds... I was googling with the device in this state when the bootloader screen pops up for not more then 15 seconds then blank again...
No way to enter bootloader mode or to hard reset the device...
I suppose the battery goes almost flat... and I've not a cradle... is there any way to charge the battery? or a way to build up a cradle-substitute?
May be the issue due to battery flat?
Thanks, Pino
Try plugging in to the original charger, not a USB cable, with the power off.
After about a minute you should see the orange LED turn on.
At least that has worked for me when my battery has been dead.
Nothing... It was already done... I suppose the charging doesn't happen if the OS didn't load... even if I read about some stating that if the charger supplies 1.0A the charge happens...
Now I'm trying to charge the battery with "alternatives" methods...
Thank you for your interest
and so?!?!?
So much lurking... noone writing?
Ideas welcome....
I've done something similar to this too, i.e., where battery gets so low that phone cannot start charging cycle.
Here is what I have done. Take note on the battery of the positive and negative terminals (clearly marked on battery). Use a regular 9V battery and some wire (or 9V connector) and connect the 9V to the phone battery (+ to + and - to -). Allow the phone battery to recharge some from the 9V. I suggest connecting for about 1 minute or so and then disconnecting again for 1 minute or so, and repeat this cycle a dozen times or (or more) using this 50% duty cycle charging. (not sure about charging current, nor heating of battery and don't want to overheat or damage the phone battery).
After giving the phone battery some (re)charging, then try plugging phone in to see if charging cycle comes on. (try first without trying to turn on the phone. If no response then try turning phone on while plugged in to USB). Generally makes no difference whether using USB plugged into computer, original charger or after market, ... phone does not, nor cannot discriminate between different 5V 'USB' sources.
If this doesn't work then the next step is to carefully touch the 9 V to the battery while in the phone and connected to USB (and to play this safe use charger, and not computer USB ... don't want to risk damage to computer). I would only try this if you feel extremely comfortable with electronics and voltages (albeit this is very low voltage) and as a last resort. KEEP IN MIND YOU WILL BE DOING THIS AT YOUR OWN RISK, and I don't want to be blamed for anything that may go wrong with the phone or otherwise by you trying this. This has worked for me on several occassions, but I am an engineer who has experimented with electronic ciruits off and on for 16 + years and so feel comfortable doing stuff like this. (again remember + to + and - to -, battery to battery).
Good Luck
First of all... Thanks for replying...
The problem isn't due to battery too much empty (it's a frequent issue, with mobile phones too...)
I suppose the Wizard needs be correctly initialized to start charging the battery and mine was in bootloader mode.
Sometimes I am able to power up the system for a little while and the bootloader screen appears but the battery doesn't charges so I cannot disconnect the power supply... this is why I suppose I'd get better times if I got a cradle.
Now I'm trying to arrange a flying connection between the battery and my kaiser's desktop charger to give the battery a bit of charge and verify my ipotesys (uh-oh... it's correctly spelled? sorry for my bad english....)
OK, wish me luck
stay tuned...
OK, no more bricked
The issue, as I supposed, was due to a flat battery!!!
I tried unsuccessfully to charge it back using the external charger for my Kaiser, probably the unsuccess was due to difficult to obtain a stable contact between charger pins and battery leads...
After that I remembered I had another battery. It wasn't used for a bit of months (I use the wizard just as backup, when the Kaiser is out of order) but luckily I stored it full charged so the battery was able to make my wizard power up (strange thing, I needed to keep the power button pressed as the device powers down as soon as I release the button!!!)
I tried to update the rom again but it failed at 99% so now I reverted to an old rom but the device is still alive...
Maybe I'll try again the update but not before having fully charged both batteries
See You and thanks to everyone tried to help...

hello all,
Has anyone experienced this? Is the USB port failing or bad?
I plug my phone into AC charger. Most often the light goes on and it begins charging. Sometimes it stops charging immediately. Sometimes it will charge for a little while then stop charging. Mostly it will charge until I unlock it again then it will stop charging. I find that once it stops charging there is no one way to get it back. Sometimes its unplugging and replugging, sometimes its just waiting until it kicks back in.
I have replaced the AC charger, changed the plug im using and changed the power strip.
Weird thing is I have not noticed this with USB charging through the PC (however that charging is slower than my rate of use, so I just get less decrease).
Has anyone seen this? Is my USB port shot? Time to get a new phone?
thanks
P.S. - Used to be Rooted MIUI, now I am back to stock FRG83 w/ stock Recovery, Kernel & Radio....this has happened since I was Rooted for the past two weeks.
Any unusual heat, when you're charging?
No. And this is a new thing that started when I started using MIUI. But has not left even after a full wipe and PASSIMG install.
Since past 3 days my galaxy note was having charging problems. It was getting charged on and off. Now its not getting charged totally.
The phone shows plugged in. and when i switch it off it does show charging sign but it doesnt charge. I have tried different charger. I have tried different battery. But it only shows charging but doesnt charge.
This is a USB port problem faced by many, you'll have to get it replaced. Just to check once if it is a USB port problem, you may try charging your battery with someone else's note. Also if you have rooted the phone, try re-flashing the ROM and see if it charges. And still if it doesn't, you've to replace the USB port, fairly common for our note!
Hi,
This phone is no charging (trying several cables and chargers with same result). Last week I was able to make a full charge with no problem. Also my laptop is unable to recognize it when some weeks ago did it. No matter is in fastboot or in normal mode.
With phone switched off appears charging animation and green led light but really it doesn't charge (no increase in %).
I have tried with a new battery, a new usb port & flex... same results. I don't see any damage in main PCB, nothing burned.
Phone working fine when power on (but no charging). I can enter in TWRP without problem too. I have made a factory reset (Pixel Experience rom)... no changes.
I don't really know what more I can do. Any idea? Maybe is there any other part involving USB than port or flex?
Thanks!
