[Q] So I have 2 perfectly good screens - TouchPad Q&A, Help & Troubleshooting

So the other morning I wake to find my touchpad sitting on its charging cable from where it fell off the table, bent the USB cable and my poor touchpad won't charge. Even better than that I had a spare touchpad that had the flash write lock issue for parts and had just swapped the USB charger board out because it was no longer charging. So I now have 2 perfectly good screens and nothing to do with them.
In was wondering if anyone had resources on the screen/touch. Circuit diagrams or howtos would be great but any input would be appreciated.

Down load an app ifixit from play and get a new USB lead as once it's bent the only place for it is the bin.

Yes I know I can spend $6 and get a new USB connection PCB but that still leaves 1 whole touchpad that needs the main board because of the flash write lock issue and my desire to reuse the screen for something else.

What do you mean "flash lock"? Have you tried touch pad toolbox?

Charging fault?

For a few days my phone hasn't been charging, and at first I thought it was a problem with the battery, but having bought a new one I've realised that when I tilted the charger to the left it would charge, but when it's just left it wouldn't, so I guess a bit of a miss-alignment.
Anyone got any ideas how I can fix this problem?
Cheers, nathaniel
try another cable and make sure it's the one that came with the phone. you should have a usb one and a ac adapter. if both are like that then you need to warranty it out.
Yeah, Ive tried it with the USB cable and the charger, I got the same result. Is there no quick fix, I'm going abroad in 9 days and quite need my phone...
There are a few discussions on bad USB connectors in these forums -- searching might provide some things to try.
From what I can remember, it's possible the pins in the connector (on the phone side) might be bent out of place -- you might want to inspect them with a magnifying glass and try to carefully bend them back if any seem out of place.
It's also possible that the connector itself is broken -- in which case you're looking at a service call.
this seems like the problem i faced. i was also facing the same problem and i read the forums here and found it as a usb port issue. so i slightly bent the usb port so that the contacts are aligned and then it started charging
Hey I would also recommend trying a new a new charger again because I have had my share of faulty chargers. Last time I had a problem charging was with a brand new cable that did not work right at the box from At&T and thought it was my battery until i tried another charger that worked. I would suggest trying the charger that is not working on another phone and see if its actually the charger or if it is your phone that is not working.

I think it is to do with the pins in the connector.
I had a search but I'm not very good on forums and I can't find anything of any use. Does anyone have a link?
Just look at the last few pages of topics, you should find something... there are threads about broken USB at least once a week.
One common conclusion is to avoid using USB cables other than the supplied one as their
plugs are a little thicker and tend to deform the phone's plug over time (I admit I always use others though, and as a result do sometimes need to wiggle the cable a tad and not move anything anymore once the connection is established... ).
I once dismounted my Hermes and tightened the plug back a bit, it helped, I've never done it with my Kaiser yet though. If you're not used to dismantling and fixing devices I'd recommend returning it for repair indeed.
I had a the opposite happen, it would charge but no data connection with my pc. If you look at your extUSB port on your phone, see if the black plastic tab is cracked (which was my case) or if the pins are shifted. whatever the issue, its obviously hardware related, take it to an At&t service center tell them whats wrong and if your in warranty they'll change it on the spot.

He got the same result using his USB cable so that would rule out the charger.

Im in England, took it to the T-Mobile shop, the service was rubish and without even looking at it they send I should send it off which would take 2 weeks. There is a crack in the black plastic tab

Recharging Options

How are you guys recharging your HD2's? I've been relying on the USB connector at the bottom of the phone, but my concern is that after 'x' number of connects/disconnects that the socket will wear out as it started doing with my Kaiser.
Do you guys know of any pin-based adapter or battery hatch modification with external contacts that would enable us to lay the phone on a stand or platform without having to use the internal USB port on the phone which will eventually wear out? The 'powermat' would be great, but it's not available for the HD2. Does the new HTC car mount recharge the phone too, or is it just a bracket?
I'm thinking of something along the lines of how bluetooth headsets recharge, where the pins are external. It just worries me that the micro USB connector will eventually fail, which on a $700+ phone is not an attractive option.
Your thoughts?
The connector will not fail. At least unless you force/damage it yourself. It has been adopted as a connection/charge connector on ALL new phones now, of any brand, so you can bet they tested it thoroughly before.
If it fails.. well that's what the warranty's there for.
To answer the original question, I charge using USB, and also an external charger for my spares.

I understand your point, but to my way of thinking it's still a physical connector made of metal and plastic. It will fail eventually, trust me. These connectors are tested to withstand a reasonable number of connect/disconnect cycles for the average user. But cell phones tend to get used more, and this phone among other cell phones because of the cpu and screen will need to be recharged even more so.
Also, I'm not talking about the point of failure, but the limit of usability. The connector on my Kaiser got to the point where the cable wouldn't stay lodged in the housing and would drop out of its own weight. Although it still worked, it made for awkward handling while in the car trying to use a coiled charging cable that would drop out on its own.
So what I was looking for was a replacement battery hatch which would connect with the internal contacts, and a corresponding mount/dock of some sort so that it would minimize the physical stress of multiple connections and disconnections.

I just got the car mount today. It Does recharge the phone - there's a mini usb plug built into the bracket, and a lead plugs into the base of the bracket, and then into your 12v socket. A nice touch, the lead is actually long enough to be able to route it nicely.

Thanks, but what I was really after is a solution that does NOT involve the USB port on the phone.
I've seen battery chargers on Ebay. That's probably the only sensible solution if you're really that worried about the USB connector...
I think I remember reading something about some sort of wireless recharging pad that you can put phones and mp3 players on that would recharge them without any cables but I've got no idea if it would work on the HD2 or if they are even on sale yet.

Yes, the former is along the lines of what I had in mind. Just surprised that no aftermarket solutions have been developed for the phone to make it easier to charge without wearing out that micro-usb connector.
As the mini USB port is a standard size, (not just used by HTC) if you should ever 'break it', most phone repair shops will be able to replace it quite easily.
A lot less hassle than opening up your phone to plug things in the back.

[Q] Touchscreen response problem

I replaced the screen on my phone myself but somehow i lost the little flap that goes over the touchscreen connector, does anyone know where i could find a replacement piece for that? Or if there is something else i might be able to substitute for that?

I have no clue, but chances are it is some kind of insulator, could you not make something out of paper or card?
And your subject says response problem? Try a screen calibration.
Yea i tried a screen calibration but it always fails though. I was thinking about trying a card or something but i didnt know if it would be safe to use tape on that part of the phone, i might have to send it to Dell
Why start two threads on the same issue? and this one is in the wrong forum.
Because my computer was messing up so i wasnt even sure if this one even posted, is it really bothering u that much?
Yes, it bothers us that much.
Sent from my Dell Streak using XDA App
I have a question about the screen... I have a big problem with it...
So my battery often runs empty. So I need to charge at several places - at the computer, in bed, in my girlfriends house.. so i bought some usb-cables for the streak... and some usb ac adaptors, like for iphone, with 12V and 1000 mah output.
So, now the problem: The cables aren'T original, but they work great. When i charge the phone with the original charger and a faked cable, also no problem. But if i use any cable with a non-original ac-usb adaptor, the screen bekomes unusable. if you want to delete a letter in a sms than, you write a m and a b und strange words, i can see the swype-line doing what it wants. same on homescreen, cant press the right icons. if i unplug the charger, everythin works fine again. i also compared the data of the original dell charger and the alternative one, same output and mah-number....
Have you ever heard of this problem?
And most important, do you know how to solve it? (please don't tell me to buy an original charger, i dont want to wast 40 € for this....
Yes, same problem with Wagan Home/Car ac/dc charger ONLY when AC charging. Probably isn't good for device, but I've never had any battery problems. Screen issues go away as soon as charger is unplugged. I just don't use the device screen when it is on that charger AC only. Works fine in car (DC).
Okay, I won't tell you that the only way to avoid it is to use the Dell factory charger (but it is)
kraz
Well, it is not, just tried the ac adaptor from my sister, worked fine
That screen behavior is caused by unfiltered output of adaptor (china, is it?).
Can be at least partially solved by using a ferrite ring or USB cable that already has one.
For example:
http://www.dataq.com/products/hardware/accessories/fc.htm
for this orice, i can also buy a new adaptor and hope that this helps
but thanks for the info
(and no, it's from great britain, but made in china )
RadioShack part #273-0067 2/bag $3.19. I realize most recent poster is from UK. This info is for anyone in USA having the same problem. One on each end of usb cable gets rid of 85-90% of interference, and makes screen usable while charging with non-original (Wagan) charger.

I replaced the screen on my dell streak myself but somehow i lost the little flap that goes over the touchscreen connector , it has 6 pins
And its call ribbon connector i thing?
can anyone help me find this part
i appriciate it
thanks
i had the same problem. I cut a tiny piece of a business card (make sure its a sturdy one though and not regular paper). Place the cut piece over the connector but under those gold pins. works just fine now

Got a really messed up USB port on one+ year old Razer 2

1) Can't charge while it is in normal mode.
2) Can't charge with USB C to C
3) Can only charge using USB A to C, while the phone is turned off. It still splashes the logo and vibrates repeatedly.
The port is not visible to any laptop, so adb and fastboot seem out of the question.
The stock recovery on this device has "apply update from SD card", so I need to figure out how an update.zip should look like.
Razer have a bunch of older stock ROMs on their site.
Can I just take the latest, rename it update.zip, put it on a micro SD and use the stock recovery to fix things?
Just saw the tear down. It's worse than my N10+ port PCB to replace.
However if the battery is getting near its lifespan maybe now is the time as the battery needs to come out anyway to replace the port PCB.
The port PCB price is probably low.

The other thing I just found is that when I use "apply update from ADB" it used to complain about init.usb.rc, init.usb.configfs.rc. I looked at both files. 0B length with 1969 date on them. What?
There must be some way to flash a recovery from the sd card instead of using the USB port.
The thing is the battery held the whole day after a night charge yesterday, so probably not the battery. I have a feeling some apps I used to "improve" the battery and "fix" the system deleted some bits.

They can cause a lot of mischief and in other services that you never expect it to.
The battery is cheap so it's easiest to replace it at the same time as you need to pull it anyway.
200 or more full charge cycles, replace.
One more thing. I bought a wireless charger to see if it is 100% the port, and the wireless charger has not made anything easier. It seems not capable of getting any charge in. So at the moment I have only one to charge it, turn it off and use USB A to USB C cable.

Probably a defective charge port PCB... you can try a factory reset or reflashing the stock firmware if really want to test it.
Check for any signs of battery (rear panel or display bulging) swelling; replace battery asap if present! Batteries can fail at any time.

I have now done the factory reset, didn't help. Nothing is bulging. I would like to flash a fresh factory ROM, but I have no access to the port. So, no fastboot and no adb. I can't even install proper drivers in Win10 PRO since the laptop does not recognize the phone, at all.
I am searching now for any solutions with the sd card. People used to do that, updates with *.zip on an sd.
Since it is out of warranty anyway now, I have finally unlocked the bootloader.
I am trying to find out if the ROMs Razer provide on their site are signed or not.

I don't know if you have had a chance to see the USB port assembly on Ebay? Some prices are close to $120. Add to that labor costs (unless you think I should do the deed myself) or costs for tools and fresh adhesive for the plastic that covers speakers, etc... and it is going cost me more than I paid for it new.

Ok, thank you for finding this, but it looks like the ribon connector wire only. The PCB besides the port also has the microphone, I think. It appears to be sold as a unit. If the problem is the wire, then sure this would be the part.
In any case, I have managed to get the wireless charger to charge. Depending on how fast the charge will be lost today will tell say something about the battery.

Unfortunately replacing the USB charge board and port in the phone doesn't always fix it. I have a box of nearly a dozen RP2 main boards I need to dig through to figure out what the actual cause of the charging boot loop

Have you played with any OS shortcut apps on it?
The Android Setup apk will get screwed up if you access it after the original setup.
Specifically it will alter the port behavior when you connect with it. Very irritating, took me days to finally track it down on my 10+
If you clear it's data in settings it may leave the null mark that's screwing it up. Some 3rd party apps can completely clear that null mark.
Otherwise factory reset.

This is a hardware issue, nothing any kind of reset can fix or app clearing. Even if you have the device entirely powered off, plug it in on anything 2Amp or higher, it'll loop

That's not how the issue I saw behaved; only happened with the device powered on and it didn't boot loop. Just an annoying pop up message.
If it has a port PCB, try replacing that. If it's just a charge port with no components on it... it's likely either corrupted firmware (reflash) or a mobo failure.
A loose connection or bad contact is also possible.
That's my guess...

New guy, coming in hot...

Need advice from PPC-6700 folks on VZW XV6700. its currently wont take charge via the usb on bottom. i purchased new battery and most i get is phone turns on for few seconds and shuts off after it hit home page. and the light does not turn red when plugged in. it was working fine up until last week.​
Maybe a bad usb port pcb. Could be a failed mobo.
Meh, bold type not needed...
Thanks for quick response. Im relatively new to diy with phones. is replacing the usb on this device something id be able to do myself? without possibly causing more damage.
Look at a tear down vid. It may not be the port pcb. You sure the battery is good and connected properly ie no bent connector pins?
No loose ribbon cable connectors?
historically that battery was never secure based off the design itslef. i may have bought dud battery... id need one more to test that theory. i have 8 different cords ive used and nada. its the old half octogon looking ones. they aren't prongs like the ones now.
I can open it up and send pic. Maybe you will see something I’m not..
You can see more than me. The port looks ok.
Finding out what common issues that device has may be useful.
For that device I'm not going to be much help other than the very basics.
Can you access the boot menu?
Use a known good power cable and charger; make sure they are good. Cables fail erratically and unpredictably.
Power it completely down and try letting it charge overnight.
ive been trying to sneak in but it shuts down if i try anything. plus i cant find one tear down video.. looks like i may be creating the first. ill sleep on it instead of jumping in half cocked.. ill give you update soon. thanks for your time.
tbh! i was gonna attempt to splice open old usb cord and bypass port using the wires directly to prongs? what you think

Get a new cable preferably OEM.
You start splicing and get it wrong or if the cable is bad at a different point... you're trying to troubleshoot it, not start new trouble
Sounded better in my head lol. but the first cord that stopped working wa replaced and did great till now. ive rounded up 4 others from storage. non seem to catch. im trying not to order a 2nd new battery and cord. even plugged into pc or laptop it doesnt recognize anything.
