HTC Diamond USB error

Hello everyone,
I'm having a problem with my Diamond. When I attach it to a USB port nothing happens. No 'hardware found sound' or what so ever.
I tried several other pc's with no result. It does charge when it is connected and the phone asks whether it needs to be in USB mass storage mode or in Active sync mode. I havent found anyone with the same problem so I'm afraid it is a hardware failure?
I tried:
-Soft/Hard reset
-Several computers/usb ports
-Disable Advanced Network capabilities
Does anyone have some tips that I haven't tried already that could help me out?
Thanks for your time!!

Disable Advanced Network capabilities under USB->PC in your Settings, that should do it.

I tried that also. With no result yet. Any other tips maybe?

First, check your cable for any marks that resemble rabbit bite marks or alligator bite marks.
No, seriously, check the points where the cable goes into the plugs for any obvious signs of damage, then check the cable itself.
Maybe, try using a different cable, if that doesn't work your Diamond most likely has a problem. If the different cable works, your cable is a goner.
Although I think there's quite a small chance that that's it, it's worth trying, right?

Use the 6.1 version of the Windows Mobile Device Center under Vista

Thx for all the tips. I didn't manage to get it working though
When the phone is connected to the charger it asks if I want to use activesync or usb mass storage. A friend of mine has also a diamond and his doesn't ask this. My conclusion is that it is broken
Damn I got this phone as a replacement for my broken K850i from my provider...They will go crazy when they see me again

Hi,
I have the same problem.
My guess is that it all started with a non compatible charger.
When charging it asked for active sync or disk.
After that the problems started, active sync doesn't work anymore.
Sometimes it workes when advanved networking is off.
Tested on different pc's, freshly installed.
Complete factory settings, notting works.
If synchronised by bluetooth it works.
I'm affraid i have to send the phone back for repairs and trow away the bad charger.

I never used a 3rd party charger.
Is there a way to update the firmware via bluetooth?? Because i'm still using the old slow version...

Same problem here. I've used my tomtom USB car charger. Is this a guarante matter, or do i have to pay for the repair?

You may have set the default connection to other than ActiveSync when first seeing the pop-up.
Go to 'Settings' 'Connections' and select 'USB to PC'.
Ensure ActiveSync is selected.
If you want the pop-up to display when the USB is connected (its good when you want to use your internal micro-SD as a memory stick), check the box at the bottom. You can select ActiveSync, Memory or PC Modem from when it appears on connection but when you just ignore it, it will perform whatever default selection you wanted last and then dissappear.
If all else fails perform a hard reset!

I've tried /soft/hard reset. No luck..
Can this be a hardware related fault, or could a ROM flash resolve the problem?
Transfering video files via BT is a pain in the a*s...

i would try a flash before returning it. You can probably dl an official 1.93.xxx.xx from htc and try that. You don't need hard spl and all that for those ROMs.

I have the same problem:
no connection at all from the PC-side. The Diamond comes up with the ActiveSync/Discdrive question and starts charging, but nothing else.
I did use external chargers that also trigger the ActiveSync/Discdrive question.
Update:
Oops, it seems fixed after a soft reset.

Same problem, diamond would not connect to PC.
Solution: Warranty repair---> they changed the motherboard, and everythings is good. Everything was free.
Edit: But now I have a different problem. I connect diamond in to PC, everything is good, but about 30 seconds after, mobile center looses the diamond, and sync won't work. Any solutions?

I have the same problem before. My Diamond USB cannot be recognised by the PC. Took back to repair and now working. But one PC still cannot recognize the diamond. The service centre told me they have reset my unit and when came back, everything has been cleared. I suspected a full reprogram of the ROM.

I have the same problem
I cant have any connection to the PC
so, no solution but the service people

USB Connection ERROR
I have the same problem. No computer seems to be able to connect to my P3700. I tried DL new ROM but I don`t know where my device came from. On HTC site from HK, which is the only one where I found a neutral Diamond with no carrier associated like, Sprint , Telus, or the like, its says The ROM Code can only be updated on HTC Touch Diamond Hong Kong English Version Device
Does anybody have a clue how to find out where my device was originally intended to be marketed? My ROM is 1.93.456.2 WWE dated July-10-2008? Do the the numbers 456.2 mean anything?
Help is highly appreciated!!

change your usb wire..

I already did. The first few times the problem occured it worked. I have 6 different USB wires and they all cause the problem. When I hook up my HTC Touch, they all work well!?

Won't sync with PC
Hi,
I have the same thing where it won't sync with any PC and i've tried all the "other" fixes and I've sent it to the service people to have a look.
Thing is, because I thought it was an issue with the usb connector I thought I would have a poke around with it myself and i could see one of the prongs looked like it wasn't making contact. To cut a long story short whilst i was trying to fix it the plastic tab in the mini usb connector came out completely
Service people are now saying that I've abused the handset and want to charge me £70 to fix it. Now to be fair, I have made it worse, but in my defense it was only because a fault had occurred that I started to dabble.
I also reported to the service people that the led light under the "end call" button had stopped working completely. This was definiatley not due to miss use.
I'm wondering if this led is on the motherboard like the usb connector is. If so, can i be cheeky and just ask them to fix the led and not the usb? but by default because the m/b would be swapped out then the usb would be fixed anyway?
If you looked at my phone it looks well cared for (which it was!!!) and its not like I've hammered it in anyway.
Anyone have an opinion or know if the led for end call and the usb port are both on the motherboard?
Thanks

USB Host Mode Issue

Okay so I am not the first one to post this thread... After reading through most of the USB Host Mode threads, i couldn't find the solution other than returning the phone and having its motherboard replaced... However, I live in Pakistan, where we don't have any HTC customer care... Plus, I have very carefully voided my warranty by S-Offing and rooting, so there's no chance I can get my phone repaired other than to sell it to some unsuspecting victim...
What I have found though is perplexing. The phone very conveniently goes into the Host Mode as soon as I connect it to my laptop. This problem started a month ago. Some said that solution lied in going to Safe Mode, but the problem persists. I tried 5 cables, ranging from high quality expensive ones to low quality cheap ones.
I tried cleaning my USB port too, didn't work. All I can do via going to Safe Mode is to get it to charge normally. That's it. I can't connect to my laptop in any way. Though I don't have much use by connecting it to laptop, but still, it'd be handy to transfer movies over cable rather than bluetooth at extremely low speeds...
If someone can help, it's be highly appreciated

Only thing I can offer is, have you tried this: http://forum.xda-developers.com/showthread.php?t=2481211
and please don't "sell it to some unsuspecting victim"... that wouldn't be a very nice thing to do would it?

Well, I read this thread and multiple other threads like this... My phone charges very well, no problems there. But as soon it sniffs a laptop nearby, it goes in the USB Host Mode... It was working good for two months, then it suddenly decided to say goodbye to laptops forever...

well you already tried the usual "tricks", but seems your phone's USB port is still messed up

Is it truly bad to use third-party USB cables?

Sony generally advises against using third-party USB cables with Sony handsets, because data might become corrupted and whatnot. So I'd like to gather some opinions on this, since I'm finding it hard to believe that using a (good quality) third-party USB cable would cause any harm. Is there anything special about Sony's USB cables? It's not like they are of the best quality either.

It's 100% bull****! (excuse my French)
And also your data may become corrupted, that chance is very VERY small and even if it happens, what are the chances that it's something super duper important.
They are just saying that you should buy their product.

Sony wanted to say that they guarantee a data transfer without interruption only with their cables. That do not exclude a same result with an another cable. If you trust in the quality of a third-party cable you are free to use it. Since the cables market it so large and the quality various so much their advise is justified.

Follow-on question regarding cables to be used during ROM upgrades (etc), if you please... apologies if this is deemed highjacking, but so far I've only found 2 threads specifically about USB cables...
Here's the deal: I've seen numerous cautions about being sure to use the cell manufacturer's cable when doing custom software ops of any kind (flashing ROMs, whatever).
The thing is, I have no idea if I still have the original USB cables for any of my 3 phones (soon to be 4). I presently use a Rocketfish cable (with USB 2.0 symbol) for all phone-to-PC and most charging.
So this is my question: If I can plug a phone into my PC, browse what appears to be everything in its partitions, plus write or delete folders and files as I please... and also run bootloader from PC and get the phone to respond as predicted...
Is that enough to think the cable is sufficient to use for software ops?
degraaff, thanks for this thread and again apologies if I'm shifting the subject too much.

I use 3rd party usb cables for both data transfer and FTF flashing. They are cheap generic ones ordered from amazon or eBay. Have had no problems and have connected and flashed many Sony phones (T, L, ZL, Z1C, Z3C) with them.

Sometimes third party cables make weird stuff happen like ghost touches and the like while charging. But i don't think that happens anymore.

Last year I lost a Galaxy S3 while trying to root it with a high quality third party usb cable. I had the original cable as well, but I thought since the third party cable is high quality too, it doesn't matter. Somehow the failed rooting attempt burnt the GSM chip. Needed to replace the whole motherboard.
With several attempts, rooting the S3 failed BUT with the original cable it worked on the first try.
I wasn't aware of what you wrote about the importance of using original OEM cables for phones but now it all makes sense to me...Be careful! Rather use original cable!

You're a power user. Can the Google Pixel 2 keep up? Rate this thread to express how "healthy" the development scene is for the Google Pixel 2. A higher rating indicates available root methods, kernels, and custom ROMs.
Then, drop a comment if you have anything to add!

How in the hell does Google let their devices languish in locked bootloader prison with carriers anymore? Why don't they give us the ability to root the phone if we're developers? You'd think you could just jump right in and unlock your bootloader on the Google Store purchased ones (unlocked ones - not Verizon trash) except they don't provide a cable TO CONNECT TO YOUR PC WTF WHY AM I YELLING

am i missing something? i got my pixel 2 from google store, and unlocked / rooted it easily the same day i received it thanks to awesome members here at XDA
it also included the necessary USB-C cable (and adapter to connect to type A usb ports)

The cable I got was USB-C to USB-C to plug into the phone and the charging brick. The adapter I got was USB-C male/USB-A female so you could attach it to an old phone and transfer contacts. You telling me you got a cable/adapter that let you connect your new phone to your PC?? I'm even more pissed off if that's the case...poor distribution QA on top of the other issues too?!

I received the same as you. I used the cable from my moto z2, not sure how it could have come with anything different than what we received.
Yes Google should have included a USB C to USB A male vs female for sure.

So Google is now responsible for you having a PC without the proper connections to plug your phone in?
Or are they responsible for you not being able to order a Micro USB to USB C adapter for a few bucks?
Which one is it I wonder...

I really want you to be saying this in a sarcastic tone, but since this is the internet and I can't read tone I'm just going to fly into a rage instead.
Are you seriously suggesting that once the pixel 2 comes out everyone on the planet immediately gained the ability to connect USB-C straight to their computers? Or is it that you are seriously suggesting that it is somehow nonsensical to at least include an extra adapter that mates this new cable type to everyone's existing computer connections? Yes we can purchase a crap-ton of adapters that get us from the phone to the ISS but for the minimal cost of this simple connection type and for the cost I paid I would expect that I would be able to connect my development machine to this device in the exact same fashion I've been able to connect EVERY OTHER DEVICE I'VE EVER HAD. They've all been able to connect to my PC out of the box. This is the first time I've opened a new device box and been at a loss for how to immediately get to working on it. Somehow I believe this was an oversight on the part of Google.

Sure sure. Totally an oversight on the part of Google that you did not check which accessoires come with the phone, totally agree.
BTW, what do you think of the included headset? I think the volume is much too low, I can't hear anything. On the other hand, I never had the cables twisted yet!

My 200 dollar Acer laptop has a USB C port and the provided cable works fine for me. USB C is the modern standard that everyone is moving to. Is it that unreasonable to think that Google would provide cabling for the modern standard that most manufacturers are adopting?

I can't be more happy with this phone.
The only thing I'd improve is to have 4 years of Android updates instead of 3.
In development they will always be on the top because of the open binaries / developers previews etc.
However....I think that over the last years security became a top priority and now a lot of people don't open the boot loader. Even Google disabled android pay when you open it.
And the price is not in favour neither. I think Google needs to release a budget Pixel at lower price...something like 400-450$.

Theres the kernels and some homebrew ROMs.
Feels like this device is hard to work on.
TWRP now fails to decrypt after the February update.
A/B partition seems hard to support so theres no official custom ROMs for Pixel 2.
So far this phone is not what I would recommend for the serial flashers and customizers.
Just a normal phone for normal users.

I see development at Linage, at AICP for our device.
GApps are now available for Android 8.1. Many changes had to be made because of project Treble.
There is development, but for now many ppl look into things on their own and not as collective.

It's something we came up with at Citibank in about 1989 - update to an unused part of storage. If it works, point whatever is using that part of the firmware at the update and use the place the old version sat as the next update space. The update crashed right on the last byte? No problem. You haven't repointed to it, so it's just empty space until the next try. Better than a bricked phone because the battery died right at the end of an update. It's about time Google caught up to the late 80s. (Yes, that was sarcasm.) My only complaint is the SD card - I have to carry an adapter around with me, and keep the SD card and adapter in my pocket. 128GB internal and 256GB external would have been nice. (I already have about 50GB used, and that's with only one TWRP backup.)
Maybe it's time to flash a kernel with speed adjustment, although it seems to be idling around 430-450MHz.

USB data transfer not working.

So i bought a used A2 for 5500 INR.
At first i thought it was a bargain but soon it turned out to be a nightmare.
The phone is full of bugs.
Worst one is that the phone only charges through the usb port. No data transfer of any sort. like an old nokia pin charger.
OTG doesn't work. It doesn't connect to the PC.
Whenever I plug in the OTG/connect it to pc, the usb options are all greyed out (same in the developers options default usb preference).
I can't even use Gcam now bcoz the PC doesn't recognise the device at all, so can't enable Camera2api, can't root, can't install ROMS... can't even buy a new phone cuz i have no money ???
turns out my phone also have the slow Emmc issue ?....read speeds are okay but write speeds are very slow... specially Random write (~10mBps).
I read many people have faced this issues. All those Posts are old, has anyone found a solution.
