As the title says it all.
Can Custom ROMs affect Device's Hardware in any way?
Recently, my Device (Vince) got a defect in MicroUSB port (charging port).
Can it be due to Custom ROMs? Maybe the high voltage defined in Custom ROM damaged the port.
I replaced the port, but don't want issue again. So is it due to custom ROMs? As if it's true, then I need to stop using custom ROMs.
P.S: I never modify custom ROMs with different kernel or anything. I just use them Stock.
Any answer will be appreciable.
Short answer: most likely not, check if whatever you're charging from delivers clean 5 volts.
A bit longer answer: Assuming one of the ROMs you used would allow more volts in some magical way, you'd also need a charger to give that higher voltage as well. Another factor you should take in is that there's a bunch of different vince models(MEG7, MEE7, maybe some others I don't know about) - the model number should be on the back of your device, take a look. I heard that some models are more durable while others use cheap silicon that gets defective or something like that.
In hindsight, ROMs are usually not the cause of killing charging ports; It's the device that charges them.
I'd propably check the voltage of the USB port you're charging from with a multimeter or something similar, if you have it - I've seen some power supplies go bad if they're old(but they are usually the 12v power bricks; never seen a 5v power brick go defective).
So to answer your question - no, ROMs cannot affect hardware, but they *can* add to it if you use a custom kernel. Usually browsing the kernel/ROMs thread will show if there's any issues with it.

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.
I own a cheap tablet, and when its battery dies i plan on hooking it up directly to an AC adapter via the port that it uses to receive power from the battery.
so my questions are:
Is this going to work?
Has someone ever attempted this?
Will it damage my tablet?
Do i need a custom rom for this?
What kinda adapter should i use? (all i know about the battery is that it has 4100mAh, havent measured the voltage yet)
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 was wondering if it's easy to enable this feature on a kernel? I saw that there were requests for it, but I haven't seen the current kernels we have listing it as a feature. If it's not too difficult, I'd like to attempt to make it work and compile my own kernel!
I'm also VERY interested in this feature, but have absolutely no clue how to go about compiling a kernel...

Generally I think for "OTG + charging" to work the USB chipset on the device has to support it and/or you have to find out how you could trick the device into enabling this mode (with a certain resistor on the USB connector and/or with a kernel modification).
The bad thing is that no device seems to support the official "USB Accessory Charger Adapter" specification. (see section "OTG micro plugs" here: https://en.wikipedia.org/wiki/USB_On-The-Go for details)

Generally I think we need to know first if the hardware would even be capable of it.
Its too bad, this makes my life just a little rougher when trying to run the tablet with a MIDI keyboard plugged in. The battery drop is so fast its almost not worth using it for music design.

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.
