Captivate build 1008 here, running stock Froyo now (but the same problem occurred with stock JH7). Not rooted, but unlocked.
The problem: the "USB connected" notification comes up pretty randomly when the phone is NOT connected via USB. When this is the case and I power off, the phone refuses to power back on. If I pull the battery and put it back in, the "spinning sun" icon (???) comes up, followed by the battery charging icon, exactly as if I had connected the phone to the charger---and the battery is shown to be completely empty, even when it's not.
Usually, after doing this a few times, the phone comes back up.
This is driving me insane. The fact that the problem is random makes me think of a hardware issue, but any wisdom would be greatly welcome. I'd hate to have to send my phone in for service or replacement :-(
Thanks in advance! M

I had the same issue yesterday. Here's what I did: turned off the phone, pulled the battery, pulled the sim card, pulled the microSD card, waited one minute, then put everything back in. USB icon is all gone!
My phone did that after I upgraded to froyo. I turned off USB debugging and powered off my phone and I have not had the issue anymore.

I'm seeing the same/similar issue when I charge my phone and remove. I can get it to toggle off by inserting the USB and messing around with the various connection prompts ("Kies" or "Mass Storage"). Don't recall exactly.
@aicirt17 OK, I'll try removing the SIM card, too (I haven't done that). I don't have an external MicroSD car. Thanks.
@mmarquis I also fiddle with those settings. It's the randomness of it all that kills me :-(

I'm thinking there is a hardware issue going on here, but any insight is appreciated.
I cannot boot from my battery. When I pull the battery and re-insert it screen shows it as empty, but... when I put in the battery with the USB connected to my computer, then it does show the battery as full. (and I am able to boot normally).
I've also noticed:
When booting this way (or out of recovery) I get a brief scrambled image before the i896 - Samsung logo appears
The battery charging and USB connected indicators will not change from what they are in when the phone is booted. So if i remove the usb after it has booted with them in, the battery indicator remains charing, and USB connected. (If I leave it for a long while, sometimes it does eventually detect it properly and switch over to disconnected).
Any thoughts would be really appreciated. I've talked to Rogers and they are sending a replacement, but I'd like to know what the problem is before I let Samsung start pulling it apart to look for water damage.
Thanks!
I found the solution to my issue:
(cannot link, search for usb connected notification stays after usb disconnected on android central.)
Turns out there was either surface corrosion or simply crud in my phone side USB port which was causing the connection mechanism to misfire or not fire at all. I guess when booting without USB, the phone thought it was connected so it just doesn't try to get power from the battery (who knows).
The linked thread had lots of responses, so I'm not sure why I didn't find it here or on android forums. I was able to fix the problem by cleaning out the port.
Hope this helps,
Hi,
Yesterday my sgs developed a fault. It can come out with messages saying USB connected or USB debugging connected, slows down, sometimes becomes unresponsive for few seconds. It can switch itself off and when i try to switch it back on comes up with "busy" sign (that spinning wheel) and sometimes is showing empty battery symbol. Only way for it to be switched on is to plug the charger. Battery is fully charged,I know it, cause its plugged in for few hours, i disconnect it, and all of sudden drops dead. Tried today with another battery from my friends sgs but it comes up with same stuff.
Can you help me?
Firmware is stock JPY flashed via odin, not rooted, only with few apps installed on it
Many thanks
Mario
reflash it and wipe factory settings
Got the phone just over a year ago so it's just out of warranty.
The phone recently started turning off, forcing me to remove the battery in order to restart it. This occurred when I turned the screen off (power button) and left it off for more than about 20 seconds. This was obviously a massive pain in the ass, so I decided to s-off, root, then put custom firmware on it.
So I plugged it into the computer and was just downloading all the required bits, and I got a phone call. I picked up, talked for a bit, then when I hung up I instinctively turned the phone screen off. I then left it for about half an hour until the downloads were done (HTC Sync downloading at 40 kbps >.<) and then went to turn it back on. Of course it had offed itself.
So I went to pull the battery out and do the usual -- to no avail. I tried outing the battery, plugging it in, then putting the battery back in (as read from a random Google result) and nothing.
TL;DR:
Here's the status:
Phone began doing the seemingly standard random turn-offs that require a battery loop.
After a week or so of this, the phone stopped coming back on.
And it will not give any sign of life (No vibrates, no lights when plugged in, no PC response)
Phone has never been dropped / watered
Tried different leads / USB - power adapters
Battery was at about 80-90% at the time of offing forever.
Tried with SIM Card in and out
Tried with MicroSD card in and out
Is this **** bricked? I wanted to wait for the Edge to come out before I upgraded; I don't want to end up with a Sensation or something.
Any fixes?

Sounds like your phone just died.
Another explanation is you have something loose, you should open it and check .

I'll take it in the an Optus shop today and start yelling abuse, maybe that will get it fixed. Worked on my old Legend. If that doesn't work, I'll open it up and have a look.
Yelling didn't work, they just tried out the phone on all their chargers and it failed.
So I'll open it now.
OK here's a picture of the USB charger bit. I can't post external links, so I'll attach it.
It looks okay... is this what I should try replacing? The USB thingy?
BTW, I unplugged everything then plugged it all back in, so nothing's loose.
Hey Andrew, I sent you a PM.
Struggling with the same problem...
Just made a call from my phone. After the call the phone seemed to be stuck on the call screen. I didn't think anything of it and left the phone alone. When i tried to use the phone again, there was no screen and the phone was not responding. I tried to re-start the phone by pulling out the battery but it won't switch on. You people seem to have the same problem. Any help would be really appreciated. Thanks.
Just a suggestion, but have you tried removing the battery and powering on with the charger connected?
I guess this would help resolve whether it's a battery/charger issue.

I have a similair issue i was flashing a rom and my phone decided to turn off or was restarted by the rom update utility and never came back on now i tried it connected to a regular power charger and usb to my laptop and it wont recognize anything. battery was fully charged when i was flashing the rom can the incredible s power on with no battery? and if mine can't and wont be recognized by pc is it toast?
After an unfortunate rooting session with my Motorola Milestone, the phone now returns into an "dead" mode. It refuses to start at all. I tried charging it and see if it starts by itself, but it doesn't budge and the little while led doesn't lit. The only time when it lit is when I connect it to the PC. I tried putting in it a new battery, taking out the SD card and SIM, but to no avail. I remember seeing a video where a guy used a dissected USB cable to spark the phone into turning on again, so I take it I'll have to use a "hardware approach"? Please help.
I tried following this guide, though without success. The phone still has that white LED lit when it's connected to the PC.
After a reply on this thread I also made, it might be possible that the battery is charged, but the phone refuses to boot at all. Is there any way to unbrick the phone in this state?
Do you think your device is really BRICKED?
If so, you can try to flash your original sbf file into your phone. Guide here: http://forum.xda-developers.com/showthread.php?t=696845
If you are using a Linux, google for "sbf_flash".
I agree with my front floor..ermm, u dont need to worry about its 'dead'. just flash original sbf can rescure your phone.
I had the same problem too, but good news is I tried to revive my phone successfully recently, btw your phone is not 'dead', it's just staying in limbo state, the solution is to pull out the battery and don't connect to any usb, don't try to power it up, it must be completely out of power wait about 12 hours, and then try to power your phone, I think there is some capacitors in the phone which retain the phone state, to make it out of power will wipe out it's state, good luck

"My phone is in limbo state... "
That's a pretty cool statement.
From technical view, it might have happened that something caused a kind of deadloop when reading scratchpad SRAM inside OMAP processor.
This SRAM, as well as the internal RTC is powered by a small battery soldered on the mainboard, while the phone is shut down and the battery is taken out.
What you did was, to wait untill this battery became uncharged.
All SRAM and RTC setting as well then gets erased.
Afterwards the CPU will start up with empty scratch SRAM, might be called a "real" cold boot
Normally the phone should not behave like this. Even if SRAM is not valid the phone should boot up...
...but anyway as you observed it like this, it might happen.
@andoruB:
Apart from that, the Milestone is hard to brick in general.
Might happen though, if you do evil things while flashing new firmware.
Especially while flashing bootloaders...
If you got some more information about the things you did, would be helpful!
Good luck anyway!

how did u root it? can u give a more detailed description? and hows ur phone? sometimes, the milestone would just shut off and wont come up if the battery is gone. Try charging it for maybe 2-3 hours, untouched, and see what happens.
Have this exact problem. Was doing a nandroid recover when the phone got stuck. Pulled the battery out. Placed it back in, pressed the power button. Nothing.
Led lights up only when connected to the computer's USB. Battery was charged before Nandroid recover. Used nandroid a lot of times but for some reason, my stone stopped playing nice.
I just removed the battery. Hoping this works. Can someone please post if you got this same issue resolved? I like this phone no matter how slow it goes sometimes. Thanks!
I completely forgot about this thread, sorry guys!
I don't remember exactly what happened, it's been so long... but I do remember I left the phone "inactive" (it's not like i had much of a choice! XD ) for 1 or 2 months, with the battery out. After I got hold of a wall charger, I plugged in the battery, after I plugged in the charger, and what do you know? It worked! It started charging (was 60% charged, fully charged, I unplugged it, but after putting it to charge again just to make sure it was fully loaded before I would flash a new ROM, it was charged up to about 80%, weirdly, so I guess it was a weird battery problem)
I do remember I didn't do anything to it, so I'm not sure what to tell you guys to do, except leave out the battery for a month or so ^^;
Device: HTC One (M7) Stock ROM
A few days ago, my never rooted, stock firmware, no unlocked boot loader, no custom ROM, never dropped HTC One (M7)'s battery died. Plugging in the charger had no effect, absolutely NOTHING. Tried 6 different cables and 9 different locations to charge it, nothing. Waited a while, dying in desperation. Then after so much of panic, I plugged it again, and randomly it started charging. But the charging had a loop - showed a bright orange LED with the power symbol on a battery for about 5 seconds, then a dim orange LED with the green battery charging, and a number, for about 10 seconds. The loop kept repeating. Eventually I could turn it on till the (incredibly low capacity) battery could live. So I did about 10 resets to it, and the situation would not improve.
Since my phone just decided to do this to me just before a long journey of mine, I was quite upset, and eventually infuriated to the limits. I decided to take it along and try different things to it - tried, tried, cleaned the ports, searched the net, nothing.
One fine day it decided to break the loop - now it charged, but only when off.
And today again its started the loop.
And here I am, begging for some help. I'm starting to hate this device now. Please help me.. :crying:
P.S. : I played a lot of Clash of Clans on the phone - it heated up a lot. Hope the info helps (Possible corrupted overheating charge instructions of the phone,etc.)
please help i love this phone cant lose this at all

I am having the same exact problem right now. its very annoying. I have to drain the whole battery to charge it again. and its in that loop that you mentioned. plus it does not charge when you put it on charge when its on. it doesnt even have that charging light. it only charges itself if its off and if there is no battery left, i have to put it on charge by draining the whole battery by using apps and stuff and i am so pissed right now i cant find a solution to this. Did you find a solution on how to get this fixed?
I am currently having a similar problem where I can only charge my phone if off. Hopefully someone can help!

I have found a solution to this. I am really happy since i am able to use my phone again.
Let me state what exactly i was going through.
I had to use the phone till it actually turned off completely consuming the whole battery and it was very frustrating because i had to deliberately use the phone till the phone shuts down and charge it. And once it started charging, it has a weird stupid way of charging. It shows that its charging and it goes off, comes back on and shows its charging, then it goes off... When it goes off the red light goes away...then comes back on.
I've read other threads and forums about people having the same issue. Others say they're not even able to connect their phones to the computer. You all should try connecting your phone to a computer and check if its able to transfer data.
If that happens, then you're saved. Because this really worked out for me.
Now, i'm not really sure what kind of bug this is, but here's how you fix this.
If you're able to transfer data to your phone, you must browse your phone on the computer and copy a file (or a couple of files - in my case i transferred a movie folder that had a couple files in it)
And guess what..i put it on charge and started charging like normal oh my god i was happy as hell
Thanks. I hope the same works for you all, people have been saying you have to clean the charging port but not really

I have the very same problem, my phone will only charge when the battery is completely drained, now i have like 25% and tried your way, my pc doesnt detect the phone :/
I tried with and withouth usb debug mode. :crying::crying::crying::crying:
Is this a sotware problem i guess? it wouldnt charge at all if it was hardware right?
Just checked and my phone now says "the usb host cable is plugged in, cant charge the device"

I'm not sure how are you NOT able to get it connected to your computer. Since i connected it to the computer, it didn't start charging but it allowed me to transfer files. And so i did. You might wanna change the cable and check if its letting you connect to your PC.
So far its working perfectly alright. I don't have a problem as such. And wait, you could install a file manager and move a couple files around. Maybe delete some files or download some files and try.
I Hope it works for everyone who's getting this problem. I know its not a hardware problem and HTC support sucks BIG time. i don't even have htc headquarters so i couldn't get it replaced, bad. but if your phone is under warranty you must get it replaced :laugh:

Hi! so you are saying that if i move some files from the computer to the phone it might get fixed? Well, i cant plug it to the computer, it just doesnt recognize the phone, if i plug it when the phone is on the pc doesnt show anything and the phone doesnt charge or anything, just like when trying to charge it with the ac charger, if i plug it with to the pc with the phone off then it shows a message that doesnt recognize the device, and the phone doesnt even charge aswell...
Right now the only fix i have found is to solve the problem of having to drain the battery in order to charge the phone, now i fixed it unticking the fastboot option in energy, now i can charge with any % but the phone must be off. Btw it gets a lot of heat while charging it this way... idk if its normal, i heard that because the aliminium case it gets more heat than normal plastic cases.
Thanks for your reply, ill try to connect the phone to the pc a few more times.
Hello guys , , I have the same problem , charging the M7 (On stock rom), I have tried many things ,roms and kernels , currently I managed to make it charge with the screen on with some conditions..
I installed SLIM ROM from their site (4.4.4) . To charge the phone with screen on I have to check "screen on while charging" (because if the screen goes off it stops charging /same thing if somebody is calling me )
To Charge my phone I just need to Reboot normally and charge it ( if you install this rom Activate the sound for the ac plug/unplug so you can know if it is charging well or not )
Eaven if i have to do these things its better then the OFF mode .
Hope It helps .
HTC M7 Only charges when it's off and the laptop can't recognize the device.
Hello, I've had this HTC M7 since last year. It's worked perfectly until a couple days ago.
The phone will not charge when it's on. It only charges when it's off. Also, my laptop won't recognize the device. I've tried with a couple different AC chargers, but no luck.
Sometimes my phone says "CAN'T CHARGE WHILE IN USB HOST MODE," and I don't know how to take it out of USB Host mode? I'm guessing this is a problem with the software. Before this happened the phone worked flawlessly.
Any help, please??!!

It can sometimes be caused by a defective usb port on the phone, does your port looks damaged? Boot your phone in safe mode and check if its doing the same thing.
I've already done that and it doesn't work.
I really don't know what the issue is? I mean this is a perfectly working unlocked HTC M7.
I've turned if off multiple times and even wiped it clean twice. I don't know what else it could be.
I mean it's been working perfectly since I got it.
But as I mentioned earlier it will only charge while the phone is off. And my laptop can't recognized it either.
It only appears and "Unknown Device."
But even when it is off it charges for a bit and then it completely stops.
Then you see the battery logo and then it starts charging again. But it repeat that same process throughout the whole time. So, it can never reach to 100%.
As I've mentioned before I've never really had this problem.
I've been looking for hours on the internet and so far nothing seems to work. There was an app I saw on to access engineer mode or something, but for some reason I can't use that app because it says that I'm missing another application.
Any thoughts??

I have the same problem, it can't charge, PC don't recognize when the phone is on android, but when i boot into recovery everything work fine (charge or data move to PC), so far i could't find any way better.
Hi,
had same problem.
Clearing system cache helped in my case.
Related cause for the trouble seem to be a couple of OTA upgrades I did recently.
(I was on a pretty old version.)
I noticed that there was something wrong while upgrading.
Even though the phone was connected to the charger while the whole upgrade process,
battery level went down...
The following procedure is your own risk!
Be careful not to choose any options that wipe all your data or factory reset your device.
This is how I cleared the system cache :
Boot into recovery (hold both volume-down and power buttons for ~30 seconds until menu shows - )
Press volume-down to choose RECOVERY and press power button.
Be patient ~60 seconds until menu appears.
Choose wipe cache partition and press power button.
Choose reboot system and press power button.
I hope this helps you.
Thanks
