Hi all,
My Rezound is having an issue where, no matter the cable or charger, it only says "USB" charging. And on my AC plug it's even giving me the "Charge Only / PC / HTC Sync" menu option as if it thinks there is a data connection on the other end.
This isn't the first time it's happened, but it's the first time out of warranty. USB charging is unbearably slow and doesn't keep up with even basic usage, so I really need to get this fixed or get a new phone (at retail, keeping my VZW unlimited LTE).
Any advice would be welcome. I have a Rezound w/ a damaged screen that I could try to pull a part from if that helps, but I'm not sure if it's just the USB port or something in additional circuitry that I can't access.
For additional information, when it's unplugged it still has the USB charge/pc option.
So when you plug into an outlet it only gives you the usb charging/pc options and doesn't automatically charge from the wall power?
The USB plug in the phone is probably bad, it can't detect an A/C charger is connected so it defaults to USB charging.
You have basically 3 choices here...
1. Get a new phone
2. Get your phone repaired, or fix it yourself. This is NOT easy to do in the Rez as micro soldering is required.
3. Try a kernel with USB Fast Charging and enable it.
This is assuming you have truly tried other cables, chargers, and factory reset.

No, it charges but at 500mA, even on wall power. Sometimes it asks if I want to mount my data, but that seems not to happen often.

Thanks for confirming that #2 is not really an option. Regarding #3, a few questions
1) How do I know if a kernel has "USB Fast charging"? Can you help identify a kernel that has this but retains the 'global' mode capability?
2) If I enable fast charging, does it mean I risk damaging a PC if I plug it into a real USB port that only wants to put out 500mA?

Yeah, nevermind... After doing a little more research into this, I determined this will NOT really do what I thought it would... It could still work, but you would have to modify the kernel settings to allow a high current (800ma-975ma) charge when connected to USB, which would be fine when connected to an A/C charger, but could be very harmful if connected to an actual USB port on a PC. Super Charge and Funky Kernel (both are in the Dev areas here) have this ability, but you make the modifications at the terminal prompt on a rooted phone, not directly in the kernel settings. Essentially you are going to tell the phone to ignore USB standards and charge at 975ma when connected to what it thinks is USB. But like I said, this could be very harmful if it is connected to a "normal" USB port and not an A/C adapter.
Super Charge Kernel (some good into too): http://forum.xda-developers.com/showthread.php?t=1902008
Funky Kernel (Sense): http://forum.xda-developers.com/showthread.php?t=1911297
S-OFF is not required (although it is recommended), but you would need to flash the kernel by booting TWRP via fastboot, NOT flashing and starting from the phone. And the kernel has little to do with the Global mode capabilities of the device, it should be irrelevant as long as the kernel is fairly up to date.
Honestly though, for the price of GSM phones now, I would just ditch the Rez and get something else... I mean you can get a phone for under $30 if you really NEED one (Lumia 520), and a nice Android device for around $100-$150 that will not only give you a new device, but one with tremendously better reception and battery life.
IMPORTANT: Especially with HTC devices, there are THREE different types of kernels for the device, AOSP, CM/CAF, or Sense... You must use the correct one for your ROM or you can soft-brick your phone. For a stock phone, a Sense kernel is required, for other ROMs you will have to look at the ROM's OP and see if it is CM/CAF-based or AOSP-based, and use the appropriate kernel.

Plugged my usb cord into my computer and it says to be plug into ac adapter cause usb is not sufficient enough to charge. It shows that it's charging but when I lock the screen and didn't even touch it with usb connected to the computer my battery just dies and its set to charge only.
Sound like your computer's USB port is screwed up and is not outputting enough current to charge the device.
If you have a powered USB hub handy, plug it into that, or try another USB port on your computer.
I'll see if that works just weird though since I was using the same port for my previous 3 phones and they would charge pretty fast but not this time.
whats odd is my gf just texted me and said that her cable isnt charging her phone at all. i'm going to have to go pick up her charger and stuff and test/return it.
Prob , you don't have the driver's installed .
My battery reading is really inconsistent was charger on a outlet said 28% rebooted then said 78% rebooted a couple of mins later and now it says 60%

This particular phone may need the entire 500mA of current that USB ports are supposed to capable of supplying. The error on the computer may be because when the phone connects, and tells the computer that it wants 500mA of current, one of three things happens:
1.) The computer says no and throws an error.
2.) The computer said yes, but when the phone actually tries to draw the current, the hardware of the computer can't provide it.
3.) The Amaze doesn't ask if it's okay to draw 500mA (to which the PC may respond no), and just starts drawing the current, causing a hardware fault on the computer.
Your previous phones may not have required as much current, therefore not causing any issues.
I don't know this for sure, but I've done some programming with USB drivers and I know that "handshake" when a device plugs in, does happen.
Happened to me to. Same thing with the notice to use wall charger. Dumb. All my other phones work with PC. Just not this one.
Just had this happen, except...
* I didn't get the "you should plug into a wall" message
* Using the USB of the computer seemed to *suck* power from the phone; anti-charging, if you will.
I've got a wallcharger on it now. Maybe tomorrow I'll try my USB3 port for it...
The USB3 didn't help...
what drivers do I need to install? My G2 charged just fine on this computer.
What I have going on now is an older USB "y" cable for an external hard drive; one side of the "y" is data + power, the other is just power. I've got the "just power" side of the "Y" plugged into a wall jack...charges fine now.

Guys, i found the solution, by trial and error...
forget about USB 3.0, drivers, micro/mini USb, app tweaks, AC usb charger etc.... You know what turned out to be the culprit ??
THE CABLE !
I realized that this charging issue happened only when using the aftermarket cable i bought from ebay, as an extra one to have on hand. While the backup cable was also OEM. (i could tell from the corn-plastic bag it came in...)
And all along it has worked fine for data transfer, sync etc, and also when charging it does in fact say it's charging... - only thing in actual it's draining.
So i downloaded the 'battery monitor widget' and kept a close eye on the mA number as i tried out different combinations of cables, stock and aftermarket along with stock and aftermarket AC chargers i had and all USB ports on my laptop.
With the cable from ebay mA was rather in negative using with all power sources, including USB.
With the stock cable from the box, it was a steady +200 to +350 on USB power, +400 to +700 on AC power.
Now the after market cable is also OEM, but it appears to be for another HTC phone, that the HTC Amaze 4G doesn't accept.
Also if your AC charger is model TC E250 it's only gonna show up as USB and not AC in battery status.
You need AC charger model TC U250 for the HTC Amaze 4G to be fired up.
There! That was what was wrong.
Hope this helps.
Is there any way to manage the USB connection when the phone is *not* plugged in? I want to be able to set whether the connection will share the int/ext SD card or be in charge only mode.
For what it's worth, I'm running CM7 Weekly 4, and LauncherPro (which I can set an icon for many system activities, but have no idea which would be the correct one).
Does anyone know how this can be done?
When you plug into an AC outlet it automatically goes to charge only, when you plug into USB it prompts by default Portal/tools..Mass storage..Charge only, you can set there.

Since it's not plugged into anything, there's no connection to manage. Just set the type of usb connection you want before unplugging it, then it should stay that way.

That's not the point. Okay, let me explain. When I use the phone at home, I always let it share the drives. But if I'm out and need to charge the phone, but I don't trust the machine - then I don't want the drives shared, even for a moment.
However, unless I can change this without making the connection first, then either I can't charge my phone this way, or I'm risking malware getting a hold.
Since the phone remembers the last setting, it must be stored somewhere. The question is how can this stored setting be changed to prevent an issue like this from occurring.
Software = unknown, hardware = easy
If you don't mind carrying a "charge only" cable with you then you can avoid the whole issue of Malware, data dumps, etc. from a unknown PC that you just want to pull some juice from. I'm not sure if these cables are sold anywhere, but mod'ing a normal USB to micro-USB cable to make it data free is pretty simple.
On a USB connection your power (+5VDC and GND) is carried by the two outer most pins on the connector while the two inner pins carry the signal (. The I would mod the USB connector as it's bigger and much easier to work with.
Using a Dremel tool grind down the two middle connectors on the end that plugs into the PC. Make sure to remove all the copper for these two connectors, but do not hit the other two or you may damage the circuit path. Even though you are dealing with low voltage and small current levels, damage to the power connectors could cause issues.
Here is one issue though that is not limited to just this method, but to any time you charge from a PC: Per the USB 2.0 standard a PC must be able to provide a total of 500mA total for all USB connections. The USB charging standard for phones says at least 500mA. In other words, if there is anything else connected via USB or the PC manufacturer fudged the spec than the phone will see it as in invalid charging device and charge really slowly.
If you decide to try this, let me know how it turns out. I have only run this in a lab setting and have no real world data on how it holds up. Good luck.

Just drag down the status bar and choose the USB Connection option to manage it and select "None." Dratsablive was right - put it in "None" mode when you disconnect at home and it will default to that when you connect again.
Nothing is going to jump onto your phone in the couple of seconds it takes to do this. Also, any windows malware on the PC will really NOT bother an Android phone.
I use PDAnet tons of times on my Droid 3, since I moved on to a better phone, I wanted to use it as well. Problem here is, My battery drains fast as hell, Normally I though the port isn't providing enough power to keep up with the draining but I used my desktop which has USB 3.0 and High power ports and still the same issue.
I already experience issues with this phone and planning to get a replacement but I'm just wondering if Anyone else has this issue and will it continue with my new ReZound?
our phone isn't a usb 3.0 device, so it can't take advantage of the extra power.
solution (level: Dealwithit)-- i found turning the screen off at least keeps power use down on the phone enough to keep it level, or gain at least a tiny bit of charge. I use wifi-tether like this, net is 0mA or ~+15mA.
solution (level: Awesome)-- make a hack usb driver for windows that just forces 1A down the pipe rather than waiting for the device to request it

You can shove all you want down the pipe, the phone won't use it unless it's tricked into AC charge mode.

I'll have to confirm, but my belief is the usb host is what dictates how much is ultimately sent... obviously it does this according to the specifications, so presumably the dumb connector just takes whatever it can get... I'd be surprised if a usb device would double check the current it's receiving from a host that has follows the spec... especially when the same port we know can take an AC charge. I have an external portable battery charger, that when it's max, it can deliver the full 1A, but as the external source drops in charge, it delivers less - so it doesn't maul it's own battery, when the external supply starts to deliver less, the phone reports USB charging mode. so I'm wondering if it just reports ac/usb based on how much mA it's getting through the port anyway.
Does anyone know what might cause this? Is it a problem with my USB port? I noticed it with my home and my work wall chargers.
Before I call Verizon (whom it has been reported is out of Rezounds, and I'm unlocked/rooted), I was hoping for some advice.
Thanks.
An update -- now after I unplug it from an actual PC, sometimes the USB/Charge and USB Debugging symbols remain in the Notifications bar. Could that mean the pins on my actual microUSB port are defective? I've now tested with a 2.1A wall unit too, and every charger I've tried has been a new USB cord.
Oh and just to rule out software I tried in Safe Mode too, no help. Anyone have an idea aside from calling up Verizon (which I will do after my long weekend out of town)?
I've developed the same issue on both of mine I've had. My solution was to simply run a kernel with a Force AC Charge option built in. Have to be careful, however, as the option may cause excessive heating of the battery if you do any intense usage under charging status (playing a game, trying to run GPS navigation, etc.) It rarely poses an issue, but just a heads-up.
You should never use your phone while charging it alwYs turn it off and set it down. When you are charging ylur phone resistors and capacitors are heatingbup your phone now if you are on it talking on it basicly you are heating up the whole board and if it gets hit enough it will losen the solder from the joint and may cause a chip creep effect on the board causi ng varios problems that are very hard to troubleshoot

Try a different USB cable. I've had cables that would charge only, no data. Drove me nuts, I thought it was HTC drivers. Swapped cables fixed it.
The charger is presenting itself in a way that looks like USB. This is very common because iDevices will not charge at all unless the charger does this, so if a manufacturer wants to support iPhones/iPads, they make the charger in this way. Unfortunately, Android devices limit themselves to 500mA when the charger is made like this. Yes, many kernels have fast charge options that make the phone ignore this, but my advice is to get a charger made specifically for Android. Use the one that came in your HTC box as a wall charger if you can. Get the Verizon branded car charger...it charges Android devices correctly.
Yeah, there are many chargers that leave the USB contacts active. Thing is, I've had an HTC branded one that used to show AC at first turn USB on me... Everything else shows USB too unless I force AC in the kernel. Seems like some other condition, degradation or something.
Thanks for the responses so far. I have tried three different wall chargers, each with a different USB cable. Other phones show AC but not mine. At the moment, plugged into the HTC wall wart, I am being asked of I want "charge only" or "disk drive".
Could this be a software related issue? It was mentioned that some ROMS have a force - AC but I am on the newest non Global RUU, unlocked S On, and rooted with TWRP as recovery.
Bump -- is there any chance the RUU and then unlocking and putting TWRP on could cause this issue? Verizon is trying to get me to run a factory reset to "fix it".
Ugh.
I got a bolt recently for parts, and it turned out being in better condition than my current one.
Only downside to the new one is that the USB port will only charge and not recognize being plugged into PC.
I've seen an app that allows wireless adb w/o root, but it requires you to be plugged in to initiate it...
Just wanted to see if there was any hope for getting root on the thing...

You may just need a different cable, or to use a different USB port on the PC.
May even wanna try a friends/family members PC if yours doesn't have at least one powered USB 2.0 port.
Most likely it's the cable, the port, or lack of drivers on the pc.
If the port gets power to charge, then the port should be fine.

The phone does work great for the most part, but the water damage stickers are bad. I popped it open and the insides look alright, but considering the sticker on the inside is bad too, there may be a chance it messed with one of the pins or something on the micro USB port. It is too small and covered for me to be able to tell if part of it is actually bad. Computer notices something was plugged in (listed as unknown).
As I mentioned, it was listed as a parts phone (claimed to not turn on), but figured I could pull the screen assembly if i cracked another one..
Same result using multiple computers/wires, leaving it to the phone.
I have rooted many of these before using the old adb methods and revolutionary, generally using your ROMs, mainly because they're made with quality and you're one of the only developers this phone has left.
I've been trying to work around the need for the USB cable, but using adb provides the permissions needed to get the files over to the data folder.. I do have ssh access to the phone, but the commands are very limited (no dev mode).
