ExtUSB port seems broken...

The ExtUSB port on my tytn2 seems to be broken, or something.
When I plug it into my computer it is no longer recognised, and doesn't even start to charge anymore.
Similarly, if I plug in any sort of charger, then the device will not do anything.
In an effort to charge it, I did the following. I removed the battery, thereby switching the device totally off, put the battery back in and then attached a mains charger. At this point I got a solid red LED at the top where the signal/charge LED is. I left it like this for 2 hours and came back to it. I switched it back on and it had fully charged the device - yet I still could not get it recognised by anything.
So what's going on here - is it broken or is this a software issue.

Ignore the reflash bit. How am I supposed to do that if I can't get USB working? Stupid question sorry. Still, I've tried a hard reset and still nothing, so I guess it's knackered huh
EDIT: Replacement is on it's way for tomorrow. Puts an end to that saga I suppose!

HTC's miniUSB port uses traces for contacts instead of pins, which I can't even begin to express how ridiculous that is. To make matters worse, the soft reset pinhole is located right next to it so one slight jab of the stylus, car keys in your pocket etc and you're screwed. You may have done it without even noticing.
Flashing roms is out of the question, but you can use PocketController to make it look as stock as possible through wifi. Another alternative is to take your device to a college/university micro-electronics lab where they will fix it for a small donation or free.

Best of luck, but it might not be the end of your saga. When it gets to servicing, if they notice something was jabbed in the miniSUB port, they could come at you with out of warranty fees.

I have insurance on my phone. It's covered for accidental damage anyway.

Yep. Figured that out the hard way. Accidently stuck my stylus into the USB rather than the reset hole.
If you're lucky, you may be able to "push" the traces on the bottom side of the connector back in place... only one side of my connector was bent. Then I gently connected and re-connected a mini-usb connector.

Where are you getting insurance ? I can't find anywhere.
Thanks,

With Orange! Orange Care. Has done me proud a few times in the past, like when I crushed my SPV M2000 on the day I got it! Or when someone dropped my SE K700i in a pint of beer.

New phone is here and instantly I have noticed a couple of things:
1) Different type of battery, as already reported by some people. It's the Dynapack that doesn't quite fit properly.
2) Screen seems brighter and more colourful - again, as reported by some people already
3) The screen tilt is much stiffer (which is good cos the old one was really loose)
4) MicroSD cover feels of better material.
5) Whole thing feels so much quicker - but that's probably just because I've not loaded anything into it yet.

Possible micro-USB failure problem!!

Just to bring this to light for people to watch for.
As you should already know, the micro-USB port on the 'Kaiser' generic WM device is NON-standard.
That is it only has a single tapered side to ensure the HTC audio headset fits inside it. The stock wall charger I was supplied with also has this non-standard shape so fits snug and works 100%.
Problem with this is that any 'Third-party' or what we would actually call STANDARD micro-USB connectors, can move around within this port with a large degree of movement (most chargers and USB cables we all use!) thus causing damage to the delicate pins/PCB connections within, specifically to the non-tapered side.
It is my opinion (and you can shoot me down on this if you desire) that many failures of chargers and computer recognition can be attributed to this.
Please believe me when I say I do not say this is a flame of the device, but I think many can use this design fault as a way of getting a FREE repair from their supplier (which is as it should be!! as they supply a non-standard mini-USB charger and a STANDARD mini-USB cable in the box)..
All those I have advised in threads before, please link those threads to this one...Thanks..
These are threads that possibly relate to the USB physical failure. Please do NOT treat them as final...we are just trying to corealate similar data.

If you have any input on any port/comms failure over and above these threads please let me know... Thanks.

The pain is, we're all going to have to go through the hassle of reflashing the device back to its original state, then lose it for a week while its repaired and then get it set up just so again when it returns!
I have an original HTC TyTN II so I'm not going to be able to do an insurance 'hotswap' this time.

Many thanks farsquidge for pulling all these threads together!

Should this be posted in a more general section? I would think this doesn't only happen to Kaiser users.. and we're not getting much of a response in this section.

I am thinking I may have that problem. I have an old shop lamp with a magnifying glass and I am still having a problem looking at the pin details on the micro usb connector. Is there a drawing out there relating to what I should be seeing?

I just tried plugging my brother's WM 2003 phone onto my computer and it detected it right away.. Can it be possible that the USB port on my phone is damaged? it works great with everything else though..

Possibly not! The title of the thread is POSSIBLE Micro-USB failure..

HTC's Proprietary USB Diagram
Click on me to enlarge:
I the reason for my RMA was that the device would only charge on wall charger. My USB was slightly lowere on the right side. I believe that someone hit it on the head when they said that the home charger has a better fit & hence, keeps the connection were the PC cable & the Auto Chargers fail.

Since we still have warranty on our Kaisers, will HTC fix it?

Did anyone fix this problem yet?

micro-usb contacts...
this thread really hit the spot.
After killing my self trying to find the answer to why i could charge my device and not synch, i ran across this. indeed it was the metal contacts on the micro usb.
Gently, using a very thin flat tool, i was able to "reposition" on the B contact displayed in the picture above.
Once i did this, I reconnected the usb cable and viola...it worked!
Thanks everyone!

I just had to return my brand new TyTN II to the store I bought it from because of this problem. It charged in the wall but would not sync or be detected with the pc.
I already returned it for a refund. I do want to get another one but do not want to keep havening this same problem.
I almost wonder if I should have kept my orginal TyTN II and tried to fix it?
Thinking of getting a Tilt now since they are so much cheaper.

I'm on the phone with ATT right now and these A$$holes are trying to tell me that they WILL NOT cover this under warranty. I'm holding for a supervisor right now.
My device will take a charge from the USB cable or my wall charger but it will not take a charge from my car charger. I even went to the ATT store and asked them to hook it up to the car charger and they were the ones to tell me to call the warranty department.
This is ridiculous. I am going to raise Hell if they tell me that I have to pay for a new phone.

They're telling me that it is physical damage and they WILL NOT cover this under warranty.
I am beyond furious right now. I cursed this b!tch out and told her to go f0ck herself.
I don't think that was good for my cause.

$79 to fix it yourself

Thank You Thank You Thank You
I have been trying to figure this out for months. I used a knife and moved the "B" pin up and it worked immediately. Did I say THANK YOU?

I went to the ATT Store where I purchased my Tilt and had the manager call the Warranty Department and tell them that there is no physical damage on the device.
They're sending me a new (refurb) one.
It's weird that I can use my USB cable and the wall charger that came with the device, but any other charger does not work.

thanks for helping me with this.
i think it's weird that any simple user, like my mum, would immediately check the connections and blow in the USB ports...whereas the advanced users forget to check the connections and straight away start reinstalling software.
Thanks again for this.

I'll be getting my replacement Tilt today. I hope I don't have any issues with it since it's a refurb.
If anyone tries to get a warranty replacement from ATT and they ask you if you can see anything wrong with it, SAY NO!!! It's almost like they try to trick you to say something is wrong with it so they can say it's physical damage.
I hope I remember to re-flash Hard SPL or I might be wondering why my rom flashing doesn't work.

see i totally screwed myself...i experienced these problems and continued to bend my usb connector all around and eventually broke that plastic piece out (first type with the holes)
http://forum.xda-developers.com/showthread.php?t=359695
and then from that being out i smashed the syncing pin over and over and that broke out...tried to solder it..got it to stay and sync for a few days then stopped syncing again then re soldered it and got isopropyl alcohol on my water damage pad so now im trying to figure out what to do...then last night i smashed the +5v and broke that pin...so i cant revert the spl so my only options are pay the 79 bucks to have ppctechs fix it or slip that plastic piece back in (its stays in even if a usb plug is inserted), get something to replace that pad (maybe construction paper...just to fool the eyes as im sure they wont give that a second look), sticking it in bootloadetr mode so it "looks broken" and try to work a att store rep into replacing it on the spot due to the boot up screen and steer away from the usb port problem as i screwed myself on that lol...any advice?

weird... trying again

I have been having this problem for a while and I can't figure out a solution.
When I plug in my kaiser to the computer, everything seems to work fine, however the active sync won't start and won't recognize the device. Also the device won't charge even though it shows the amber ligtht and the screen become brighter when I connect. I have the same problem with my car chargers.
If I use the HTC splitter (USB and Audio) everthing works the way it should be. But if I use a direct cable, bypassing the splitter nothing works. What is in that splitter that makes everything work? About 2 months ago, I didn't need a splitter to have it working. Is it a Rom issue?
Guys I do need help. It just drives me crazy.
Thanks.

Could be a slightly damaged mini usb connection. Have a look at the bottom of your kaiser and see if any pins are moved in the USB ext connector.

Yeah guy, I reported this issue with Kaisers & specifically Tilts 6 months ago. Have a look at your USB port pin on the device. If it is curved or the right side of the pin is slightly lower (Not arrow straight) then you may have sloppily placed your stylus on a soft reset. Sometimes this can be fixed by VERY GENTLY bending it back into shape with the stylus or another semi-rigid & smooth tool, that's if it not to badly jacked up. Because it charges in the home charger I'm about 90% sure that's your issue.

you guys are right. THe usb was slightly bent. Upon reading about the problem, I straighten it back however still the same problem. I am looking into getting a big magnifier to see if I see anything out of order.
In the meantime does anybody know a place in Toronto who is capable to fix this issue? I know a lot of people have problems but I don't want to send the device away.

Is my USB port busted?

Tried connecting my kaiser to 2 different pc's and it won't get detected. The device will charge but activesync won't pick it up. Also its not listed in device manager! I tried disabling/renabling advanced network functionality as well has soft reset the device several times. I'm on the verge of hard reseting BUT when i put my device in bootloader mode it only says serial.. will not say USB as its supposed to
any help would be appreciated.. i'm on death v4 rom btw.
thanks in advance!

Can you get an activesync connection via Bluetooth? When you inspect the extUSB connection can you see anything which looks wrong (such as a wire sticking out/in more than the others? What happened preceding this problem?
If you hard reset the device I don't see the relevance of the bootloader. It'll just restore the original image from where it's tucked away in the devices ROM. If it was working fine straight after you installed the ROM thats on it now and doesn't work after a hard restore then that points towards a hardware failure. If you have to go down the path of restoring to a different (original) ROM for returning purposes, there are ways of doing this with a microSD card - although I've not tried. I think the wiki would help there.

bluetooth activesync is working, i did a hard reset and nothing. Flashed to romeos via microsd and now its acting all strange.
After it completed the flash from microsd, i soft reset the device and it rebooted backinto bootloader.. i removed the microsd and soft reset several times and it kept going to bootloader. I attempted to hard reset as well and same thing, would go to bootloader. Removed the battery for a couple minutes and still same thing. Plugged it into USB with it off and it turn on by itself and go straight to bootloader. Unplugged the USB cable, took out the battery and put it back in, then plug the USB cable back in and this time the orange light came on as if charging and it finally booted up. The above has happened to me previously on my hermes but that was when the battery was extremely low, my battery level is currently at 97%!
now its booted into the freshly flashed rom and still same thing... charging but not being recognized by the PC... i've checked the usb port on the device and everything looks fine.
I'm lost at what to do now....

This might be a stupid reply but I had the same problem. My cable was busted so you could try another cable.

I am in the same situation here
Tried it with 3 different PCs with 3 different cables.
It's charging, Active sync pickes it up and trying to connect but fails to connect.
The only think I can come up with, I used new charger in the car. May be it killed the port
Is there any way to find out for sure?

i tried 2 cables with 2 different pcs... its only charging it and the computer won't detect the device at all. Nothing under usb in device manager.. even in bootloader, it only says serial not usb. I've downgraded to a shipped AT&T rom and Radio through the storage card but i still need to downgrade the SPL before i attempt to get a warranty exchange. IS that possible to do with through microsd yet?

I'm having the same issue. The usb port charges the phone fine with the USB cable, but teh computer does not detect the device. I also tried the headphones and they work fine as well. Help!
Update: I just tried a different usb cable, and now the computer recognizes the device, but as an unknown device.!!!!!

Thanks for that suggestion but still no dice
The computer isn't detecting the device at all! Usually when a usb device is plugged in you can go to device manager and look under USB and see it there, but its not showing up. I've scanned for hardware changes several times and nothing.
I've now tried on 3 different computers (2 pc's and 1 mac) with 2 different USB-MiniUSB cables and nothing!!
i guess i'll just go to the at&t device support center tomorrow and hope they'll replace it on the spot and notice that i've changed the SPL...

can i ask for the people that are having this problem to do the following.
With your device unplugged from the PC open device manager. (Right click My Computer -> Properties -> Hardware (3rd tab) -> Device manager) Then expand the last tab (Universal Serial Bus Controller) and plug in your device.. if it doesn't show up then click actions -> scan for hardware changes..
I just want to make sure if your computer is detecting your device or not..

just an update with my situation. i went into the att device service center today and told them my problem... the guy behind the counter had no clue what he was doing. he just looked at it like a monkey for minutes then swapped it out for a new one. no questions asked even though it was hard spl'd, cid unlocked, and sim unlocked.
but now this device's vibration is really weak and i lost my invsishield protection on the front (kept the battery cover and my ppctechs scren protector)

Busted? or just won't work
Hi all,
I have been coming to these forums for a little while and only posted a couple of times. I felt this was important. I was having the same problem. Tried the cables, resets, ROM changes the works. I have had my at&t tilt htc 8925 for 36 days when I reported the problem to them. But it actually started about 10 days before. At&t tech support was very rude and accusatory when it came to them "helping" me. I, like probably all owners of a phone like this treat it like gold. It is very important to me. So when I contacted tech support and was told it was probably abuse or I had "buyers remorse" (I don't want to return the phone I just want it fixed!?)
The best they can do and they do not budge on this is for me to return the phone for an exchange. BUT, and this is a BIG AT&T but, the phone they exchange it with is refurbished. Something someone has returned. I do not want a phone that has been returned. I want mine fixed. "This is my phone, there are many like it but this one is mine" Know what I mean? When I bought the phone the guarantee was "we'll just replace it with a new phone" and I like 1000's of others did not ask if that "new phone" was refurbished. It is. Now advocates will tell you as they did me, refurbished is actually BETTER than new. Huh? Then why aren't all phones sold refurbished ones? And if they are so great, take mine back, give me one of those "crappy" new phones and give mine to someone who wants a sweet refurb. I am outraged by the whole mess.
I have searched forums and complaint sites. The bad usb port problem is NOT an isolated incident. There are a lot of people with the same "it charges but won't sync" problem. This is a known problem they refuse to address. Their stand, send in for refurb.
Personally I would like to see a recall fix class action against at&t. It can be fixed but they just don't want too. I thought I would be relatively safe buying for a huge company. They spend millions on advertising to simply leave their customers twisting in the wind after 30 days. Very bad business.
That's the rant. So I decided that if the warranty was useless anyway I'd take a shot at it myself before sending out for repair myself. There is a place in California PPC Tech http://www.pocketpctechs.com/main.asp?area=home that will fix the usb for $79 and ship it back to you in a few days. They seem to be reputable and a lot of people are opting to fix this problem themselves.
How did I fix mine? by altering the mini usb end of the sync cable. I tried other cables and connectors but I think it has something to do with the contact points. The only way mine would work was if I plugged it in, wiggled it slowly and with a little bit of pressure at times, around until the screen brightens. That means it has made a connection, then don't move. Hold very still. It took both my hands. Wait for what seems like 2 mins and it would start to sync. Based on this. my repair (before I send it to California for repair, which I may end up doing anyway) is make sure the plug on the phone is straight and not damaged. If you can get the phone to sync this way you may be able to crimp the mini end of the usb very very slightly to make the connection you are manually doing by wiggling it around. It took a lot of small tweaking but it now syncs about 29 out of 30 times. That's about as good as it gets.
So good luck to us all. If you can't get it to work yourself send it out west to PPC Tech. In this economy the phone companies like at&t better start getting their customer service back on track before they have no customers to service, It has happened to the biggest before. Wake up AT&T! The days of the business model of massive turnover and new signups is coming to an end as people tighten their belts. Treating current and future users poorly is a sure fire way to put yourself out of business.

here is my gift to you all..

read this post and check EVERY SINGLE LINK in the first post...i had this issue and i ended bending my usb plug every which way until finally i broke the plastic seperator off and in turn smashing the second pin from the left on the top off (the one in charge of activesync) over and over until it broke...i didnt really care i could still flash by sd but then i smashed the + power pin and so i was on the phone with att for many many hours explaining to them that its a known issue to users but not to the company and they finally sent me a replacement..i should have just searched my butt off before trying to deal with a problem/fox it myself (yes i dissasembled it and soldered the pin back on and it broke off multiple times causing me to dissasemble it many many times and smashing it again and i ended up getting alcohol on the water damage void pad which i replaced) learn from me...if you ever have ANY problems that are significant..dont try fixing JUST GET A REPLACEMENT...who cares if its a refurb..if the refurb sucks then send it back until they send you a new kit...after 5 returns you get a new kit soo just keep sendin back them refurbs until your happy

oh and to make it easy on yourself because if you tell att you have a usb problem its NOT covered under warranty and will take you many many hours like me to convince them otherwise (which someone eventually will understand because certain people ARE familiar with this problem at ATT it just depends who you get and how many times youve been elevated in support)..what you need to do is IF YOU CAN return your spl back to stock (if you manage to get a long enough connection with activesync) but if not dont worry too much att doesnt really check spl just that you have the shipped rom on there so load the shipped rom (found on here) on your sd and flash back and just make up some excuse that it isnt working right and youl get a replacement or if you can get the spl revrted jus throw your device in bootloader by a failed flash (pull the usb out during flash) and say its stuck in the funny colored screen lol

jaysjob, i've been dealing with ppctechs for a long time (probably since '03-'04) they're very reputable and highly recommended. They actually got the contract to be the authorized repair center for I-Mate about a year ago.
But why would you pay $79 for something where u can get a complete replacement? Yah it might be a refurb but my device that i turned in was all scratched up from drops.. the images on the start, ie, and messaging buttons by the d-pad had scratched off.. and now the device i got looks brand new (i actually think it is a new one but i never asked if it was a refurb or not)
pazookie, what your saying is true.. always take advantage of the warranty if you have it. If you dont and you want to repair it yourself, know what your doing! I'm very handy and have done many lcd replacements and other various repairs on cellphones (nokias, HTCs, sony ericsson, samsung, motorola, u name it!)
My little brother has the n82 and he bought the black case, I told him to wait for me and i'd help him do it but he got impatient and he thought it was gonna be a simple swap. He ended up breaking his LCD doing it which set him back $80!
anyways i'm happy now with a new device but i'm gonna go back tomorrow and get it replaced again because the vibrate is extremely weak!

Hi fone
Thanks for the reply.
Yes, I agree with you. If the phone has something else that is messed up like you were saying a scratched screen or buttons. It's just that I am as careful as I can be to keep the phone in nice condition just to send it back for maybe one that someone didn't take the same care of.
Mine works good now. I think it has something to do with when I crimped the cable end. It make a tighter fit. I think that may be the key to mine and others problems. For sure it is becoming more and more clear that there is a design flaw whether att wants to acknowledge it or not.
Thanks for your input about PPC too. If I do end up having to fix it that's probably the way I'll go if that is still the only thing wrong. Otherwise it's in for the warranty as you suggested. I KNOW I'm not that smart.

Im having this same issue and it is definately not a cable problem.

if u think its a hardware problem then take it to a service center. The guys there just follow step by step guides on how to diagnose phone issues. For me he saw a crack in the usb jack on my device and just replaced it. If you send it in to HTC i think theres a higher risk of them figuring outu the device is hard spl'd and wont honor your warranty.

taylor, I'm not saying it is a cable problem. I am saying it is a hardware port problem. I "fixed" mine, probably temporarily, by crimping my usb cord so that it holds more firmly in the port. I did say if you have the same problem and you use the same test I did ie: move it slightly, Gently, not like others I have heard stories of where they ram it from side to side until it snaps off, that you might be able to do what I did. I thought others with the same problem might be able to use this workaround until at&t figures out it is not an isolated incident with thousands of people having the same problem thats all. Hope this helps.

I had a similar problem. Phone would charge fine, but windows didnt even recognise anything was plugged in. Interestingly the bootloader changed to USB when the cable was connected, and Serial when unplugged.
As it turns out (thanks Flying Kiwi for suggesting the obvious I had overlooked) the middle top pin was recessed too much into the plastic guide, so I stabbed it a bit with a scapel and all is well.
So it seems that the Serial/USB section of the bootloader cant even be trusted.

[Q] Touch screen behaves very weird.

Hey guys i just bought a nook color and had it shipped to my country but i think i am already regretting it now.
The touch screen starts behaving very weird randomly at any times, it automatically registers touches and keyboard automatically typing own it own, and what ever i touch just goes straight to hell and this continues as long a i don't lock and unlock it again.
Even when i am reading it automatically starts zooming.
I was think about rooting it and installing a custom Rom, will that fix the problem? because giving it back to B&N is not an option for me.
Also i don't have screen guard, and the screen is always smudged with fingerprints, can that trigger this sort of behavior?

I'm using mine in Australia and have a similar problem but only when using the supplied USB cable to charge it.
I've heard stories about faulty USB cables which might be the case as I don't have this problem when I use the cable for my desire. The problem with this is that the cable isn't long enough for practical use and the supplied cable apparently has extra pins which would explain why it still discharges (although slower) when using my desire micro USB cable.
For now I'm limited to only using my nook without the cable plugged in but I'm thinking about finding another cable as sending it back to B&N and then paying to ship it back here isn't really a viable option.
Let me know if you figure something out though.

Well the one with usb cable is a known issue and u can still use it otherwise, mine just happens randomly at any time, its almost unusable.
Does installing a custom rom help?

It wouldn't hurt to try. I know some kernals make changes to the touchscreen sensitivity but I don't know whether that would apply to your problem or not. A nook is very easy to un-root anyways so as far as I know (and don't quote me on this), you should be able to return it if you absolutely have to.
Don't give up though. I'm loving mine and for the price it's an awesome little accessory when it works.

Hi,
Make sure to clean the touch screen - last night I had a different looking
smudge on my screen that was causing huge problems - as soon as I cleaned
it off, back to normal. Are you in a humid location? Condensation will cause
problems too.
Also you may want to search for 'calibrate' in the forums, there is a way to
recalibrate the touchscreen sensitivity, I believe that this is mostly for
low sensitivity at the corners though.
Here are two links I found:

Good luck!

My touch screen acts up as well. I turn the screen off for a couple minutes to "reset" it. It will work OK for a little, then it goes back to wonky.

Hey guys i finally found a solution to this problem, well my touch screen is behaving normally when its not not connected to the power cable. I hope thats a solution good enough for you.
Just go to

I tried all the custom roms but that didn't help very much, so i tried this on CM7
and so far my screen is giving totally normal tests results when not plugged in and lets hope that it stays that way.

My daughter had a similar wonky-screen problem when she plugged in a particular set of portable music player speakers. Not another pair she has, just that one.
And I was able to replicate it on my nook. It wasn't specific to her nook.

okay, it seems that my excitement didn't last that long but
After a lot of testing, it turned out that the only problems was my oily or moist fingers.
so i got a screen guard and tested it for more than two hours and i haven't had any problems yet. So even if i do see that happening again, once in two hours is not that bad.

I think I'll try this cause I have oily fingers as well and I'm getting the wonky screen issue while NOT plugged in as well.
