How to unlock when my USB port broken?

My phone is cingular 8125, my USB port can't sync with PC, I don't know what is going on. When I plug the cable to PC, it tell me unknow device detected. I can't do anything thur USB. Can I unlock by SD card or IR port?

Have you tried connecting you phone to a different PC? Also deinstall Activesync and reinstall it (are you running 4.2 or 4.5).

are you able to charge your phone with the AC/DC charger? if so ur port isnt broken.. so try doing what mmrfrazzz says and u could also go a step further and try uninstalling the usb port drivers then reinstalling them. do your other usb devices work? does ur phone indicate its charging when plugged into usb?

I have 2 8125, the other one is OK. I am using Activesync 4.2. I replaced the USB port, it's work for minutes. After dinner, it only charging but not sync!

From what I understand from your post, it sounds like you have a cold solder joint on the contact or contacts that carry the sync signal; you may need to re-solder these. It only worked for a few minutes because when you applied pressure to the USB port by inserting the plug you compromised the already weak solder point. It works when charging because it charges over different contacts then when it synchronizes. It seems your first solder job was not sound.
PS. If the solder is dull (not shiny), it usually indicates a cold solder joint.

I had this problem with an 8125 i bought on friday for 20 bucks. they had broken the usb port. so i took one out of a razr phone and put on the 8125. at first it would only charge thru usb but not hook up on activesync. but then some how when i soldered it it worked and was able to update it and all that crap. The only thing is that it will not charge with a regular charger. it will only charge when connected to a computer. but hey atleast it works now.

Yes, I was re-soldered the USB port. I have compared my workable and the un-workable one by electric-meter. They are same connecting status, but just not work! I can be charge but not synchronize . Is some IC or chips damaged?

which program do you use to over clock your 8125? can you post here or send to me? [email protected]

I use batterystatus. but the thing is is that some devices respond different to speeds. for example my MDA can only be overclocked to 286. anything higher it freezes up. On my 8125 i can overclock it to 299 with no problem at all. So its trial and error. try it out and see what you can get.

Fast Charge, Charging Pinout Questions

Sorry if this has been covered elsewhere; I couldn't find anything.
I'm looking into getting some spare chargers for my Tilt. I read at Pocket PC Techs that the device has a distinct "fast charge" mode, that uses a special pinout. Is this true?
If so, does the charger that comes with the Tilt use this fast charge mode? It seems to be just a standard mini-USB charger (data sheet here).
The link to Pocket PC Techs is actually to an adapter that they sell that is suppose to give you a fast charge with any USB charger. I'm wondering under what circumstances I'd have to use this.
Anyone know what the fast charge pinout is, and which third-party chargers use it?
Thanks.

ISTR reading something about pins 4 & 5 being tied together on some chargers -- should be very easy to test this.

I have not tested this but I suspect the pin out is the same as the Hermes:

The USB charging is done with different connections and at a different mA rating. The mains charger is 1000mA and is what I would call the normal charging system (but what the site you show, refers to as fast charge - but only by comparison to USB charging) This is just about standard for many sync/charge PDAs and not a special feature of the Kaiser.

I do notice a huge difference in speed comparing my old razor usb power adapter vs usb cable into my computer vs tilt power adapater so it prolly makes sense

Yep, the Razor adapter only delivers 500mA not 1000mA

Plus the razor charger does not have the pins 4-5 shorted, this is a HTC tweak that lets the phone know that it's on a charger vs std. USB power and it may in fact charge at a higher rate upon detecting this. I just know that my Hermes occasionally did strange things like turn off BT radio and other odd things when connecting/disconnecting from different chargers. Kaiser seems better at this.

For a couple of weeks now, I have been charging my Kaiser at work by using the adapter that came with my Audiovox SMT5600. It's been working fine. I cannot however determine if this charges any faster or slower than the Kaiser's adapter.

Slow Charging
So that would explain when I use GPS in the car with my old RAZR charger why the battery still drains. Darn, looks like I'll have to buy a new car charger.

USB Charging
are there any issues iwth battery drain or lif when charging with the USB cable connected to a computer?
Thanks,
g

Is there a specific USB charger.

The pin out is the same as the Hermes?

I wouldn't think it would need to be tested. As per this page:
HTC has developed a range of accessories that are compatible across all HTC devices for consumer's ease of use. These include the BH M200 (Bluetooth headset), HS U110 (3.5 mm audio adapter and headset), and the HS S200 (HTC standard stereo wired headset) to enable effective communications on the move.

If the audio adapter and hard wired headset are compatible across all HTC devices (per HTC themselves), then that confirms that the pinout of the audio side is the same. And it's been mentioned earlier that the data side follows the mini-usb standard, which I can confirm: I'm using the usb cable from my camera to connect my Kaiser to my PC at home, while I use the supplied cable to connect it to my work PC.

I would like to use my old Himalaya MDA II Hands Free DSP Car Kit for my new Kaiser (as that I only have to buy a passive holder).
I tried to find a ExtUSB 11-lead Pre-wired Connector Plug ....but it is impossible..any suggestions?
It should be something like this one http://www.gomadic.com/comip10leadp.html

Sorry, can't help you there.

I am experiencing a similar issue with an USB/car adapter and the USB cable that came with the Tilt.
Ran Google Maps yesterday with GPS on and when I got home my phone was almost empty. It was charging the whole time in the car though.
Does this mean I should look for another USB cable that is shorting those pins?
What about these adapters that plug into the phone and allow you to connect a USB cable for charging and a 3.5mm audio plug?

Mmm, that is a unique piece!! But the cable seems somewhat short.
I think at the end..I am going to combine following pieces to make the final connection to my old handsfree carkit.. (I hate soldering)

Any problems with me using my old Razr car charger on my Kaiser? Typically I charge mine every night with the standard charger but in case of emergency I'd like to use my Razr car charger
Thanks

In answer to the original question, yes, pins 4 & 5 are shorted on the OEM charger that ships with the Tilts, thus enabling it to fast-charge the phone at currents greater than 500ma.
Hopefully this helps,

Tilt Charging Issues!

I flashed my ROM to Dutty's WM6.1 WWE and it's GREAT!
But there is a problem i've found. When I go to charge it with a car charger or a wall charger, the mini usb port on my tilt won't recognize the charger.
Which is funny because when i put it in my docking station to connect it to my PC it works just fine. It will sync and charge.
I've checked the chargers and they charge other phones but not mine.
Is this a fixable issue?
Thanks in advance!

charging

I am thinking of getting this tab to replace my acer a510.
Just wondering i think i read you can only charge using acer special cable??
Does this tablet have a usb/micro usb that can trickle charge while screen is off/asleep
example my a510 can trickle charge slowly if i hook up a usb to it, but only when the screen is off.
Acer use their own special usb plug to charge normally.
I want to use this for long traveling etc and only want to use a micro or usb from the car to get some juice into it.

I don't know. On the TF700 it was possible but on the TF701 I don't know but also didn't try it.
But I think when connecting the charging cable only to the tablet it will charge with any 5V usb charger but just very slow.

Page 17 of the manual.
http://dlcdnet.asus.com/pub/ASUS/EeePAD/TF701T/e8803_tf701t_em_v2_for_web_only.pdf

You need the special cable to charge, but you can use it to trickle charge from a PC or (presumably) a car USB charger with the screen off. Fast charging requires using the special cable with the Asus mains adapter.

That is because the AC plug of the TF701 charges either with 15V/1,2Amps or 5V/2Amps, while a normal USB 2.0 hub is limited to 0,5Amps (USB 3.0 to 0,8Amps). If you have a vehicle charger with USB slot the charging speed depends on the max. current it can supply .
And also: there is no micro usb slot on the tablet or the dock.
btw: What Acer did really sucks,because they just switched + with Data+ and GND with DATA-GND from the USB pinning, so you _need_ the original Acer charging cable. (My brother has the A511,where i already repaired the cable once due to lead fracture)

QI wireless adapter won't charge phone anymore - XZ1 compact

Hi all,
I have an XZ1 compact (Model G8441 non-root) that I'm very happy with, but I can't get it to charge wirelessly.
I bought an adapter with a USB-C plug and it worked to charge the phone at first, but it suddenly stopped working after a few charges.
I figured I had a fault with either the wireless receiver that plugs into the phone or the charger pad.
I tested the receiver via a micro-USB adapter on my old Z5 compact and it charges fine. I also bought another charger pad, and it also won't work on this phone.
When the phone is on the charger pad, the indicator on the pad recognises that something is there and goes from green to blinking red as if charging, but nothing happens on the phone.
If the phone is completely switched off, all I get is a blinking green LED on the phone.
I've tried it with the case on and off.
There have been three updates since I got the phone a few weeks ago. Is it possible that an Oreo software update has broken the low power charging somehow?
Obviously I've rebooted the phone, but I haven't done a factory reset.
I'd appreciate any help you could offer.

You could indeed try downgrading the phone to determine if it's a firmware/software issue or a hardware issue.

I'm confused. The XZ1 Compact doesn't have wireless charging. What did you buy to wirelessly charge it? Something that plugs into the USB port and then sits on a wireless charger?

Yes, I bought a wireless adapter with a USB-C plug that connects to the phone & lays against the back of the phone inside the case. You then place it on a wireless charging pad.
I've done the same thing with several other phones & never had a problem.

Didn't see it explicitly mentioned, did you try using a different USB-C adapter cable? Since the micro USB cable works, we can safely assume the pad's fine. But I didn't see you cross test another type c cable.

Solved
Hi all,
I managed to fix the problem by replacing the QI receiver attached to the phone with a new one.
Strange that the old one worked if I connected it to a different phone via an adapter (and that it worked to begin with on my phone).
It must have had a problem where it couldn't output enough voltage to charge my new phone, but had enough to charge the old one.
Thanks for your help.

What I had changed was the charger pad. I tried two different ones, a USB-C powered one and a micro USB powered one. Neither worked.
I have a new QI receiver on order.
