Posting for a friend.....
He just got the samsung tab. As soon as he got it home, he updated to the newest software to 3.2
Started the root process but quickly found out when he plugs his tab in via USB, it does not come up with an option for USB storage. His computer reads it as an audio file. He says he does have debugging checked.
Any ideas? If I can get more info from him, I will update.
This happened to me after I used a car charger that would at best only trickle charge... Does it react normally when plugged in to a wall outlet charge? Mine would still show as "discharging."
I never found a solution and mine was replaced by the Retailer.
not really sure if drivers are on this problem. try updating them though.
Hate to ask... Has he rebooted? I would try disconnecting the cable, toggling off usb-debugging and rebooting. Toggle it back on , then connect the cable....
Hi there HTC fans.,
I'm having a problem with my HTC Desire 500, and I really need your help because I can't really figure out the cause of it. Basically, my phone just doesn't want to charge anymore.
The problem first started at work. I had to download some photos from my phone into the PC from work, and I did that using a data cable from one of my colleagues. At first, the phone didn't connect to the PC, but after I unplugged it and connect it back, it worked and I was able to copy the photos I needed. However, a notification message appeared on my HTC's screen. The message was "Your phone is in USB Host Mode" or something like that. I'm having this Desire 500 for about 6 months and this message never appeared before when I copied things from or into my phone. I ignored that message and I unplugged the data cable and carried on my work.
When I went home, I tried to charge my phone but that didn't worked. I tried the both ways available: directly with AC charger and connected to my PC. But nothing happened; no charging signal, no red LED on. Nothing. I tried to go into fastboot, and even made a factory reset, but still the phone didn't charge.
However, I noticed today that somehow (by a miracle) the phone started charging when I used the same data cable that I downloaded those photos at work.
In conclusion, my HTC Desire 500 can't charge unless I use that specific data cable (from one of my colleagues).
So my question is: why is this happening and how I can solve my problem?
Thanks in advance for all of your answers and sorry for my bad english.
Maybe USB port is damaged? Check if there isn't anything suspicious inside your phone USB or the cable plug

Thanks for your answer, lgiK.
1) regarding the phone's USB - I don't think it's a problem with the phone's USB jack, because the phone actually charged with the data cable from the colleague that I've told you about. He also has a microUSB cable (like all the other Android devices).
2) regarding the cable plug - I don't think the problem is with the cable plug, because I've tried to charge the phone at home with 3 different AC chargers (all from other Android based devices), but it still won't charge.
I really don't think that it's a hardware problem, I suspect that it's more a software bug (or something similar). I think that mainly because that message appeared for the first time ("Your phone is in USB Host Mode"), although I'm having this phone for nearly 6 months.
Did anyone had the same problem like I do?
If you switch off your phone charge it?

Last night my phone completely ran out of battery and has turned off. I put it to charge on a normal AC charger, and I noticed this morning that his battery was full.
So... yes, I suppose the phone charges when it's turned off.

Then try factory reset. Maybe there is something wrong in the software of the phone. Switching modes USB is a software issue. In the USB host mode, the phone is not charging.

I've already did that, but no change occured. I also tried going into fastboot (that also didn't helped). So i'm running out of options. The phone is still in guarantee, so I'm thinking I will just take the phone to them.

Guys,
I had the same "in USB host mode, can not charge" problem when the power is on, after 3 months of use of my new HTC One. It may be related to the charger but I am not 100% sure. It was very annoying and I had to turn the phone off before plugging in the power cable to charge. It happened when I was in Taiwan, so, I called the HTC help line there and they gave me a solution.
The guy on the other end asked me to go to Power setting and click off the "Fast Boot" and "Power Saver Mode" options first. ( I am not sure if these steps are necessary, but, anyway I did as he requested.) Then, power off the phone by pushing down "Power Off" for 2-3 seconds to allow restarting in Safe Mode. Once the phone restarts in Safe Mode, some of the Apps may not work but the phone can be charged normally. After restarting my phone in it's normal mode, the "USB Host Mode, Can't Charge phone" problem was gone. I can charge your phone normally and also click back on the "Power Saver Mode" and "Fast Boot" options in Power Setting, without problems. I hope this will also work for your phone.

Check the usb connector. And then just send in for repair.
I have a stock Droid 4 with a mugen power extended battery. Last night I got a vibration that felt like a Facebook notification on my Droid 4. I pulled it out of my pocket and tried to turn it on, but the screen remained black. I tried holding the power button to reset it, but there was no response. I tried plugging it into my wall charger that usually works with a usb cable that also usually works, but even after an hour, there were no signs of life. I tried plugging in the cable to my tablet, and it charges just fine. I've used other cables and chargers, still no luck.
I tried plugging in into my laptop with the cable I normally use for charging and my laptop picked up that a device was connected. I looked in My computer to see if I could access the phone internals, but I just saw a drive letter with motocast, and 2 other drive letters that told me to insert disks in to them. The motocast drive letter had what looked like motocast system files, but that was it. I had an SD card in my phone, but no drive letters that came up when I plugged the phone it let me access it. When I went to safely remove it, I saw in the device manager that it correctly identified that a Motorola XT894 had connected to it, and I safely removed. I've tried doing a soft reset, holding the power down+vol down button for 10 secs, but that does nothing. There are no lights at all, not even when I plug/unplug it from the charger.
I'm planning on going to a cell phone repair place today to have them remove and troubleshoot the battery ( I don't have plastic torx and I'm afraid of short circuiting the motherboard)
I feel that there is some hope for fixing the problem or at least data recovery since windows recognized my phone and I could at least get to the motocast folder on it. I do wonder why my phone is able to be recognized by my computer but still show no signs of life otherwise. Any ideas?
I love this phone, but it sucks with this happening around the holiday season.If it can't be fixed, I'd at least like to get my data off it. Please help!!
Is there any way to fix this? Would physically removing and reinstalling the battery work? Do I have any options for file recovery off my phones internal storage, especially since it seems windows recgnizes that my phone is connected?
UPDATE: Got it to power on and boot normally once. Enabled USB debugging when I had the chance.
Got back from the cell phone repair place this morning. He said the battery was definitely bad, drawing zero amps. He also said he was getting weird voltage spikes throughout the board, and I think he said something about the PCMI power management chip being bad and that the phone was done for. I told him that I could plug the phone into the the computer and it recognized it. He said my best bet might be getting a battery off eBay that would power my phone long enough to get everything off of there. I asked if it could also be USB cord related as I tend to have horrible luck with them. He said it could be and that the reason that I was able to have the phone recognized by USB but not charge is due to different pins communicating during USB connection. I'm including these details so you can gauge this guy's expertise. He did go from saying the phone was done to suggesting a new battery/USB cord, and I was able to power it on after using said cord.
I went and bought a new USB cord and plugged it into my inverter I had in my car. To my surprise after a few seconds, the phone was showing the charge screen with the battery at 70%. It still wouldn't boot up so I kept it plugged in for about 5-10 mins. Eventually it did boot up. I immediately went in and enabled usb debugging. All my data was there. For a brief bit the date and time was off, but even that corrected itself. I played a song from my music collection on my SD card to make sure that was OK. The song played, and shortly thereafter it looks like the phone powered back off as it had originally done. I hooked it up to my computer and my PC started installing new hardware, it said something about xt894(my phone) a couple of disk drives and a CD ROM drive, and something about adb. The furthest they got were as unknown devices, so I disconnected them and reconnected them a couple of times, eventually the install icon went away. It still recognizes the phone and even recognizes there is a storage device with the phone in the device manager menu, but it still says "please insert a disc into drive (letter)" The drive with just motocast is still there, and I think there was another CD ROM that was recognized, said to insert a disc same as the drives. I threw it on my wall charger for a few minutes, but it still wasn't powering on. I then realized that charging it could exacerbate the voltage spikes the guy was talking about, and I didn't want to risk it especially after seeing all my data there, so I unplugged it.
I do have the battery that the extended battery replaced. It had to be pretty much tied to a charger, but it did work if only for less than half an hour. So there is the option of using that to temporarily power the phone.
My new questions are:
Am I at risk of further board damage if I charge/power on the phone? What about charging the degraded but functioning battery?
Now that I know I have USB debugging enabled and my computer still recognizes my phone, how do I go about backing up the contents of my internal storage?
Could this all be effectively solved by just getting a new battery? What about what he was saying with the weird voltage spikes and PCMI chip?

Have you tried it without the extended battery. That could be the culprit of all this going on. If your original battery is bad get a new one and charge it. I had the same problem with a battery till I bought a new oem battery. After I charged my Battery I had to go to fastboot to get device to boot with a fastboot cable. Then while connected to that cable I backed up my contacts. Then while still connected to fastboot cable I flashed stock firmware and started all over again havnt had a problem since.
I'm waiting on an OEM battery to arrive. I was able to save everything off my SD card that was in the phone, so I am increasingly hopeful. Do you have to go into fastboot if your phone is stock? What is fastboot even?

AP fastboot mode is where where you flash stock while connected to rsd lite via usb or fastboot cable. It is part of bootloader. You hold down all three buttons to get to boot menu scroll down to ap fastboot then hit the vol. up button then connect to computer after you have rsd lite active. then flash stock firmware. If you get a battery that doesn't charge have them send you an other one that has happened to me a few times but not many. Remember when you scroll in boot menu you only have a few seconds to pic what you want to do or the device will try to boot.
The OEM battery I ordered finally came yesterday (no thanks to USPS). I tried multiple chargers and outlets with a good cable, and still nothing. I have another non-OEM battery arriving tomorrow, hopefully this one was just a D.O.A battery.

It was probully a dead battery. It sat for to long. If you had a fastboot cable cable you wouldn't need a battery to flash it in rsd lite or just to see if it would boot. There was this one time I had to order 3 battery's just to get one that worked. Sometimes they been sitting for to long being the device was made in 2012.

So your saying if I had a FastBoot cable I could boot my phone without a battery in the phone? Would it wipe my internal data/OD?
Update: I have had a BIN-TEK battery charging for several hours, still nothing. Good cord and charger too. The only other options I have is the extended battery that crapped out on me but powered on briefly, or the puffed out factory battery it replaced. Things are looking bleak
OK

It is so you you can get to fastboot mode so you can flash. It is usable with a low battery or no battery at all. When you first connect it to computer it will automatically start booting. Here is a link for one: https://www.amazon.com/gp/aw/d/B00K...boot+cable&dpPl=1&dpID=41ep3FoxgHL&ref=plSrch
If it boots to your ROM when you first connect it then you have battery problem. If it does not boot to rom then you should leave it connected and flash stock firmware from fastboot mode witch you will need rsd lite to flash. If it boots after that then it us just a battery problem. If nothing happens then you probully need a new droid 4. Remember once you disconnect fastboot cable device will go off. So don't disconnect until you are done with everything being that you don't have a good battery.
I have a fastboot cable now. Haven't tried anything yet but I plan to today. I've looked around XDA for firmware If I need to flash stock firmware, I found several versions for the Droid 4 here:https://forum.xda-developers.com/droid-4/general/droid-4-xt894-firmware-mirrors-2015-t3004048 how do I know which firmware is correct?
Also, am I good to disconnect the fastboot cable from the PC as long as I am NOT in the process of flashing firmware?
I have ADB debugging enabled on my phone, and last I checked my computer recognized my phone, just couldn't access internal files on my phone. (Had "Please insert disk into drive x" message) Any options there?

You have the right index get the one says
4.1.2 - VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip just in case you need to flash. just connect cable and see if device boots if not flash the firmware with rsd lite. never umplug cable unless you want the device off because when cable is is pulled the device will go off.
I connected the fastboot cable without a battery in the phone. Held power button, computer detected it. Said it had found an XT894 and Motorola Network drivers or something like that. Said my installed hardware was ready to use. Noticed in device manager and network connections that Motorola USB networking driver #3 was installed. Under My computer, didn't see any new hard drives. I have RSD lite and the firmware you told me to get. RSD light shows my phone model, imei, software, ect and says that I am connected. But there has been no activity on my phone's screen. No Motorola logo, no menu's, nothing. I would feel more comfortable if I could pull my data off before I flash the phone as I have read horror stories of flashing gone wrong. Is there some way I can access my phone's memory since the computer recognizes it and backup my files before I flash?

When the device is off just connect the device to your machine and it will boot to your rom thats it. It will do it automatically. No need turn it on yourself. If it wont boot then something is wrong with the rom. If that happens and you were running a custom rom and not stock go to safe strap if you had it installed and use that to boot back into stock rom slot. Now you have two scenarios you can use. Do the first one I wrote first. If you Have safestrap installed then do that if it wont boot. Dont forget to have to have the drivers installed for the device on your windows machine. On windows based systems you have to have the drivers installed installed before using rsd lite. Just in case I forgot to mention that.
My ROM and phone is stock
Another update: I'm trying to use ADB to backup my phones files before I flash. Here is what happened:
Sorry for the lack of updates, been busy. Anyways, I got adb installed, plugged in my phone, did adb>devices, didn't show up.I got the newest version of Motorola device managermanager and had it update. Plugged in my phone again, computer said it found an XT894 and Motorola USB networking device, told me to restart my computer. Restarted, tried to see if adb detected it, nothing. It shows up in my device manager under networking devices, it even says the location is an XT894. But adb still doesn't see it.
The weird part is that RSD can see my phone too along with device manager. I'm planning on flashing to see if I can unbrick my phone, however I want to try and backup my files on there just in case the flash wipes my phone.
Is there a way I can have my computer recognize my phone as a drive instead of a networking device so I can get my files?
Is there any way to get my data off my phone before I flash?

The only thing I can think of at the moment is safestrap If you had it installed before you bricked the device then you could try booting to safestrap and then mount device in safestrap and copy and paste all your internel sd stuff you want to keep. If you did not have safestrap installed then make sure you have correct drivers for device installed and try the adb command again and see if it reads. I'v been in your situation thats why once a month I now back new stuff up. When I had the s3 I bricked during bootloader unlock. Took me three days with an image file to get it to boot. Then I reflashed the stock and didnt need the image file any more. That was long time ago. i learned to back my stuff up after that. I just thought I would mention that just so you could have a food for thought. Also data will be lost is another reason to back stuff up.
