USB host notes/questions - Galaxy Note GT-N7000 General

Hello World,
So I got my USB to go cable from ebay, and I decided to try it.
Some notes/questions:
1) When I tried one of my card readers, it immediately failed with 'USB device suddenly disconnected'. Is there any way to remove/readd a new device without yanking out/reinserting the USB OTG cable? It's really tight.
2) I tried another card reader and it showed up in /mnt/sdcard/usbStorage.
3) I think I unplugged it without 'safely detaching' it first via the notification bar. After that happened, I noticed my battery was draining curiously fast. Betterbatterystats showed that I had something called USBStorageUnmountter going berzerk and keeping the phone active. So be warned.

8125 Dead

I have a 8125 and I was able to unlock it fine. After unlocking it I upgraded to the underground crossbow edition rom - which the 8125 rebooted and was running. I tried out a couple things and everything seemed to be running/working fine. It was getting late so I put it down and went to bed. This morning when I got up the phone was off so I went to turn it on and nothing happened. I figured it just ran out of battery power plugged in the charger and guess what no red light on. I have tried everything under the sun but I cant get it to charge or startup. Anyone have any ideas? It was working fine.
i know u said u've tried everything and i don't mean to sound like i'm takin the buscuit, but leave it on charge for n hour, then try bootloader. taking the battery out completely for a while could work.
i had so many problems with crossbow! think this was one of them.
Unplugged
Well so far I left the charger plugged into the phone with the battery in it for over an hour now - with no luck. The red charging light doesn't even come on. Did you have that problem? I also left the battery out and plugged in - still nothing. Tried taking the battery out and then putting it back in while plugged in - no go.
I have not tried the "bootloader" - but the phone will not turn on at all or respond in anyway. Its in a powered down state (or so it seems) - I dont think bootloader will work?? But I dont know anything about bootloader - is it on the ftp site and how do I use it?
Any chance the battery could have been completely discharged?..just a thought. I think i read that completely flat batteries wont charge up via usb. Disregard if thats a silly suggestion, just thought id offer my two cents.
try getting a new battery and see if it boots up...it can be your battery.and you are trying to charge with an AC adapter right?
Wall Charger
I am charing it via the wall charger (not usb) and I am going to try to get another battery. Just weird that I never had a battery problem until I install the wm6??!! Unless the damn thing drained my battery dry and somehow damaged the battery. I called Cingular and they are sending me another unit as its still in warranty. So we'll see when I get it - I will try the new battery. Strange. Very Strange - because everything was working last night.
Strange
Well after leaving the battery out all afternoon I took a go at the phone again, put in the battery then turned it on. It actually started booting up - showing the WM6 bootscreen. After about a minute it shut down like it was out of power. Strange. I know the phone is not bricked because if it was it wouldn't have just done what it did. Anyone have any suggestions how to fix it?
Could be a bad battery. You need to test out with some one else battery

New Battery
Well I finally got the new battery I ordered today. When I put it into my phone it will boot into wm6 fine but will not sync with activesync 4.0 or charge via USB or plugged into the wall. I uninstalled activesync, rebooted my computer and installed Activesync 4.5 - but still no luck with the phone via usb syncing with my pc. Also when the phone in plugged into the wall via the wall charger it does not charge. I am beginning to think the port on the bottom somehow was disabled from the rom update, although I dont see any posts with people having that problem. I guess my next option is trying to reflash it to stock rom via a sd card since it wont connect via USB - however I can not find the information step by step how to do this. Can someone point me in the right direction?
Try going to the bootloader screen: Turn off your phone and then hold the camera button while you turn it on. When you are at the Rainbow screen (thats the bootloader) plug in your USB cord. You should see in the bottom left (above the left soft key) where it says USB. If it doesn't then I'd say your USB port is broken (I'm not aware of any ROM being able to disable that).
As for flashing from the SD card, I believe thats documented in the Wiki...

Battery icon has yellow triangle and thermostat icon

Hello all,
I left my phone charging over night as usual. When i woke up i was surprised it had only 32%. I plugged the charger back in, but the phone wouldn't charge. I restarted the phone and when it booted up it had 60%
After some standby time it showed 50% .. really confusing. I pulled the battery out and when i plugged it back in and "before" turning it on. The green battery icon came on flashing with yellow triangle and red thermostat (see pic).
It won't boot up until i plugged in the charger. I left charge until 100% and tried to restart. I got the same icon again and had to plug the charger in.
Anyone know the meaning of this? Battery app showing temp as 36C after boot up. Now it shows 34C. I did attempt battery stat wipe too.
Please share with me your thoughts.
EDIT: I returned mine for a replacement. After that, my nephew admitted that he spilled something right over the usb.
I had a similar problem. When the icon comes up plugged in, yank the battery out and shove it back in.
If that doesn't work, when plugged in take the battery out, unplug the phone, put the battery back in, and then plug it in.
It worked for me!

HEY!! that worked for me. Thank you sooooo much
OK guys, it came back again. The issue is not resolved. Perhaps a battery failure?
I waited for my battery to completely run out. Then charged it all the way up. Then a simple battery pull out and in takes it down to around 80% ?!
Strange stuff here.

Sounds like a very delicate procedure xD
it seems i am the only one with this issue :/
Sounds like the battery just isn't being calibrated correctly.
Let it drain fully and then take it out and put it back in. Chances are it'll turn back on. Let it drain again until it shuts off and then charge fully while the phone is off.

late update ... got a replacement .. i tried everything ..
i've this problem..
does anyone resolved it?
i don't want return it to samsung...
Same problem here. The phone is "charging" even without the charger plugged in (!) When I turn off the phone a green battery icon with a yellow triangle and a red thermostat is flashing. Can't turn it on without a charger plugged in Tried everything. Anyone else suffering from this?

Probably your USB got polluted or bended.
i also think it is a usb issue. i updated the original post. By the way before i returned it for a replacement i tried using a qtip and "contact cleaner" and sprayed some on the usb. After 30 mins i was able to charge normally before it was acting up again.
Bottom line: clean your usb.
Cheers a bunch for your replies! Gonna clean my usb again & carefully "bend" it down a bit. I'll post the results later
Hahaha I laughed so hard in a bus after reading your edit. What a cute nephew
I feel sorry for you though
Tried everything, including a couple of factory resets/wipes. Sent it to the service center yesterday
For me the main idea from using SGS2 for cpl of weeks before selling this crap:
'Do NOT buy korean smartphones !!!'

I cannot disagree more. This is the most fantastic phone I've ever had. Feel free to check my signature. I've had worse. Haha. Much worse. This phone has only lagged twice in the months I've had it and I had to do a battery pull once. I've had my iPhone 4 crash more times than this phone.

I've had charging problems with my SGS2 as well. All of a sudden it started switching tap&talk on and off. Turned very warm and drained the battery juice.
When I attached the charger, it didn't show signs of recognizing that it was attached. I tried to switch it off, and on again with cable connected. Then it started charging, but if I unplugged and tried again it failed again.
So I had to send my beloved SGS2 for service. Now heading on to two weeks without it, i'm growing desperate from having to spend the time with my old Samsung Spica.
Have a look at the charge port problem thread in general. Few of us have had this problem for various reasons.

i also have a kind of similar problem on my S2, suddenly it stopped charging, when i plug it in i tries to start up but isn't able to & then restarts.
i get the normal battery sign when you plug it in after the battery completely dies (no thermometer), nor does the phone or battery gets hot. is there any solution or should i just take it to a service centre? BTW my phone is rooted & loaded with a custom ROM.

[Q] hearted-shaped icon over battery

Sorry guys actually I am not a wp7 user but my friend who owns a HTC Surround ATT Version T8788 insisted to ask me for help on his phone. His phone has a little heart-shaped icon over the battery bar which i believed that it is battery save mode for htc wp7 phone based on my research. I do actually did all possible ways to get rid of this problem but still it cannot be resolved.
What I did:
1: I tried to charge the phone (via pc usb cable and adapter) in long term but it failed, in contrast the phone would switch on and off rapidly. My Zune and PC cannot detect the phone via pc usb cable.
2: I pressed on the settings mode in order to try to disable the battery save mode but when I was getting in there it freeze for a while and it popped out to the main home screen. It did not allow me to get into the settings mode every time unfortunately. Same goes to any other apps and modes in the phone.
3: I failed to get into recovery mode since there has not much battery left. The purpose I did so is because I wanted to try to do a factory reset over the phone.
4: I tried pulling out and in the battery for 30seconds but still not gonna switch on the phone unless it is charging (but still i face the problem on (1) while charging).
5: I bought a new battery which i believed it has at least 50% of the battery life in it but it is still not allowing me to get into settings mode to disable the battery save mode. Not just settings mode but other apps and modes as well.
My apology again because I really lack of idea on resolving my friend's phone so the only way I can do now is to post this thread in htc surround ATT Version T8788 xda forum. Lastly, I do appreciate someone who can help out to solve this. Million thanks for any of your reply and co-operations.

1. Are you using OEM cable? No adapter should be required, if you are using a different cable pc might not acknowledge phone.
2. How are you accessing settings? Settings can be accessed from "Settings" app on app list; swipe to left, swipe up, tap to open.
3. ?
4. See 1., also try charging @ wall outlet it will charge much facter than through USB, again OEM cable recommended.
5. I do not think that batteries com with 50% charge. I could be wrong but when I purched my device it had only a residual charge ( enough to boot and make a few short calls).
If low battery charge is issue you should also receive message "Battery Critically Low" upon boot. If you cannot access any apps once booted and icon is still appearing over battery you do not have enough of a charge. If your only option is to charge though pc give it plenty of time it should chare even if not using recommended cable. Charging will be indicated by flashing red LED. Turning off your screen should speed up the process (it will take several hours plugged in to USB).
Hope this helps.
Thanks for your response and patience! Actually i just resolved the phone problem Monday ago.

[Q] Charging Problem - Verizon xt907

Trying to fix a family members xt907 so here's the situation which has been nothing but headaches for me:
1. The Phone is only 7 months old and the bootloader is unlocked so warranty exchange is out of the question. She let the battery run down until the phone died. Then without charging the phone she turned it back on and it died again. From that point she couldn't get it to charge or turn back on while plugged in. At this point she brought it to me.
2. I got the phone and did a soft reset which finally got the charging screen to come up (showed the actual charging icon and the fill meter would flash up and then back down periodically). Problem is it never went past 0% after charging all night. I went ahead and tried to power it up thinking maybe it was just a glitch with the charging screen. Phone wouldnt boot. Just stuck at the Motorola logo. Another soft reset and the phone finally boots but now the battery icon showed a '?' and status showed '5% - Unknown'.
3. Performed a factory reset. No change. So I used RSD to flash the stock 4.1.2 firmware/kernel/modem, etc... What I found strange here is that despite the low battery Fastboot AP showed battery as OK, not low and let me flash (bootloader is unlocked, not sure if that affects low battery flashing or if that safeguard just wasnt built into the M).
4. So phone boots back up and shows 7% battery. Plugging in the charger at first notice has no affect. Battery stats shows '7% - Not Charging'. So I unplug the charger and the low battery warning pops up. Plug it back in and phone still doesnt register as charging, but says 'Not Charging'. Then I notice that the lockscreen shows '7% Charging'. Weird. Regardless of all that, the battery was not charging. The percentage never goes up and after reboots the percentage will remain the same. The battery does slowly discharge on the charger if I have it powered on.
5. I tried flashing a couple different roms before flashing back to stock and all had the same problem. I've formated /system hoping it was a problem with the OS but it didnt help. All of these charging tests were performed with the stock Motorola usb cable plugged into the wall charger. I tested the Motorola charger against my S4 to verify it works and also tried my Samsung charger on the Razr and it made no difference. However, booting the Razr M up with the Samsung charger resulted in the '?' in the battery icon and a notification in the status bar saying something about a CommServer starting. This notification was persistant and could not be dismissed. If I reboot the phone with the Motorola charger or no charger then that notification and the '?' dont appear.
6. I should also point out that I opened the phone up and disconnected the battery from the board and discharged the board. As a last resort I completely removed the battery and peeled back the tape on the bottom of the battery to expose the + and - terminals on the battery and wired it up to a stripped down charger and left it for a bit. Upon putting the battery back in the phone it showed a charge of 30% but still had all the same problems otherwise. So the battery is capable of taking a charge, it just wont take it through the phone, whether powered on or off. Thats what leads me to believe the battery itself is not bad. Its not practical for her to pull the battery to charge it, obviously. The phone detects the cable being plugged in and I can transfer files via usb cable to/from the computer no problem, so I'm fairly sure the Micro usb port is ok. Just refuses to charge.
A little lengthy but I'm at my wits end on this and really dont want to have her buy a $50 battery and then its a problem with the phone. I dont usually get stumped when it comes to fixing something but this one really has me. So if anybody can shed some light on this situation it would be greatly appreciated.

I presumed you tried to wipe the battery stats via the battery calibration app? not that I think it would make a difference. another option is enable/disable USB debugging. you could also try charging into a PC or a different outlet (perhaps that outlet does not provide a good current)?
not really sure, just tossing out some ideas...

I actually installed cwm recovery just to wipe battery stats. Im assuming it works the same way but I'll give the app a try. I'll try anything at this point. Tried your other ideas already though and didnt make any difference.
I appreciate the input. I'll give that app a try and see if it does something different from wiping battery stats in recovery.

Doubt it. However, the issue seems to be with the hardware, and since it is not a software issue, Motorola could honor the warranty. Last resort would be to unroot and see if you can get an exchange.

What did you have it plugged in to? The fact that it said it was not charging indicates maybe you didn't have enough power coming through the charging port...

No. Verizon finally sent her a refurb replacement. I got the battery to charge up by taking it out and rigging a charger to it. But the phone still wouldnt accept a charge with the battery back in and it lost the charge it did have 2-3 times faster than normal. Battery Stats also showed the battery was showing a pretty decent voltage so unless the battery itself has a low charge circuit that gets tripped I'd be hesitant to point to the battery itself. And the charger port transfered files just fine and the phone recognized when the charger was plugged in (would go from 'discharging' to 'not charging'. So yeah, I was left stumped. Hopefully somebody else can get this solved for you.

Just an update: I ended up buying a replacement battery and it fixed the charging issue. I rsd back to stock. Then, playing around with it, I booted to bootloader and selected "Factory" and it immediately booted back to stock, but, the battery had a "?" again. Ready to throw the damn phone against the wall, I rebooted it. The "?" is mysteriously gone. What is the "Factory" setting? I think I tried it before, but had CM10.1 installed. My theory is that this "factory" boot from bootloader actually soft bricked the phone. Either that or the issue was truly the battery and simply replacing it fixed things. I am up and running now, cm10.1 is flawless, imho. Thanks for the quick reply and I hope this helps anyone with similar issues.
Beware of the "Factory" bootloader option...........
Here we go again. Upon a reboot into recovery. Recovery is twrp 2.5. What I notice is the motorola boot img takes an extremely long time (2 minutes) to turn off and cyanogenmod to begin. Could there be something corrupt in the bootloader? Is there any way to reload the bootloader on this device? Anyone have any ideas? Could it be Recovery?

Power drain issue!

I've been having power drain issues for a couple of months now, have tried almost everything but issue isn't resolved. Will replacing the motherboard solve the issue? Coz I suspect a wakelock issue. Below are what I've tried.
The battery has started to drain big time and the Android system is consuming most of the power.
1. Calibrating my battery.
2. Factory reset to January update.
3. Stopping the apps running in the background.
4. Turning off location, wifi and internet.
5. Tried disabling backup of photos.
6. Disabled app preview messages under Google.
7. Tried replacing the physical battery at the service center.
8. Currently running on the June 2018 patch.
Despite doing all this the battery drains big time, even when it's idle, when I'm sleeping.
I'm unable to upload screenshot because it keeps saying that there's a network issue. But the screenshot stats say that the android os consumes most of the battery and SoT was 30 minutes. Phone was idle for most of the time. It came down 100-20% in a few hours.
Android OS is eating away most of the battery.

No, motherboard replacement won't fix the issue. It looks like there's an issue with deep sleep. try a custom kernel and see if that helps
While my drain is not as bad as the OPs, it is bad. I have taken to turning on Airplane mode when the phone is not in use. Overnight drain is 20%+ when idle if not in Airplane mode, 1% if it is. SoT has gone from the original 6-7 hours to about 2.5 to 3 hours. Battery health is at 96% according to battery app. Held awake seems to be very high if not in Airplane mode, with almost 3 hours overnight when the phone is not in use. Main battery use is from Kernel and Phone. HOPEFULLY these issues will be resolved with 8.1 or P, but I won't hold my breath.
Unfortunately none of these issues were addressed in 8.1 and I'm not sure if they even recognized this issue, for it to be solved in future updates.

You're probably the only one or one of the very few with bad battery drain (80% in just a few hours while idle) on the stock rom so you probably got a lemon or its damaged from a fall.
Flashing the Jan 2018 rom wasn't smart at all since there was alot of news that the first Oreo update was very buggy and was pulled. 8.1 is also buggy and also got pulled. Best to flash the stock April rom for less problems.

Thank you for your response. The phone does not have any physical damage. Flashing the Jan 2018 rom was a move by the service center despite telling them it wouldn't help.
I managed to figure out using GSAM that the issue is being caused by 700000.ssusb kernel wakelock and I have no clue how to fix it. Do you have a workaround for it?
As this option is USB related, you could try changing the usb mode in developer options:
Settings>System>Developer options>Select USB configuration - change it to "charging" (I note mine is currently MTP)
I'm 100% guessing here but maybe if it's set to charging it won't be looking for OTG devices?

I've tried setting it to all possible modes under USB configuration including "charging", but doesn't seem to help.
OK, it was only a thought.
I did read on another thread someone say they plugged and OTG adaptor (no OTG device attached) and it stopped the problem, not a solution but worth a try, if you have one.
Have you inspected carefully with a torch inside the USB hole for any debsit that has got in there?

Yes I read about that work around too. Haven't tried it yet as I do not have an OTG adapter. Will post a response once I try.
Haven't inspected the USB port either, will do.

Can you try this:
Reboot phone, when its rebooted, plug the charger in and out once.

Most of the threads have a reboot method that works for the user but they all vary a little bit, this works for this user:
In my case a kernel wakelock called "7000000.ssusb" was keeping my phone from entering deep sleep. I resolved it by plugging my charger, unplug it and turn it off immediately, wait a few minutes and reboot. However it is a specific solution for that bug.

I think you might need to play around a bit and see what works for you.
Don't forget to do the Better Battery Stats dump I posted in the other thread.

I've already tried the plug in - screen on - unplug - reboot, but did not work for me. I'll post the dump over the weekend.

I'm just noticing this today,
When I click on the USB configuration and set it to "Charging" from "MTP", it doesn't actually change.
The pop up that shows different options shows that it's in charging but it's actually still in MTP. I'm not sure if this could be the cause.
Do you know how to fix this?

Screenshots for USB configuration not getting switched.

You need to back out of developer options and go back in again to see the change.
Plug the charger in
Change mode to charging
Back out of developer options
Re enter developer option - should no be on charging.
Plugging in, changing the selection, backing out and going back in does not show changes: Change setting to Charging->back->back. Developer options-> Select USB Configuration shows Media Transfer Protocol, while the Selection itself shows charging. (it's plugged in, so makes sense) I tried changing this to Music Transfer Protocol last night and it made zero difference in the battery drain. I just tried the plug in, turn off, unplug thing. I will let you know if I see any difference. USB port is clean under 5x magnification. NETLINK and timerfd shows more activity than 7000000.ssusb on my device, but all of them are higher than they should be I think.. NETLINK shows 324644 wakelocks!!! Timerfd shows 65337 and 7000000.ssub shows 33256! The thing is, the phone has been used very little since the last full charge!
That's odd, I dont have the issue and when I choose "charging" it stays on that setting even after unplugging the charger. Each time I re-enter developer options it's still set to charging.
The fact yours changed links in with the wakelock, your phone appears to think something is plugged in which is why I asked you to check for debris in the port. I'm wondering if you have a damaged usb port?
If it's software related, I don't think resetting it will help, I'm no expert but I'm assuming as its a kernel wakelock & I'm sure a reset has no effect on the kernel? maybe others can advise.
I wonder if flashing the stock Kernel would help, I'm only thinking out loud, I'm sure others can give better flashing advice.
Do the wakelocks show up while charging?
Your next step really has to be to post a dump on the official thread, a few people are complaining about this battery drain but nobody has posted a dump to the official thread yet.

Yes that's exactly what's happening as described in first point.
I observed NETLINK sends more wakelocks but if you see the time it kept the system awake in the background would be comparitively less.
