extUSB Data Cable? Not needed anymore!!!

Last night when I was half a sleep I plugged into my HTCTouch Pro a standard USB cable in its ext USB port. It started charging and I went to bed. When woke up in the morning, I was shocked and I was a fraid some thing could have happened to the devive. I immediately unplugged it.
I checked the device and there was nothing wrong with it. I decided to test it further. So, I connected the "wrong cable" again and I could exchange files normally with this standard USB cable. I also used for active sync and Internet sharing!
I also connected the standard cable the Pro's charger and it worked like a breeze. This means that if you need an additional USB cable you can buy a cable at quarter the price of the damned "extUSB" one!
Hope I provided you with some useful trick.
Note: Use it at your own risk. But I tested it on my device with no problems. Perfect!

Sorry to ruin your excitement, but pretty much everyone knew this already. The ExtUSB is a standard USB plug but with extra pins on the edges that only ExtUSB cables have receptors for. They are just audio and video pins, and aren't required to charge to transfer data.

LMAO!!
You are the second one that made this "amazing" discovery!!

Third, actually, and my post didn't even seem to surprise anyone: http://forum.xda-developers.com/showthread.php?t=444534
However, with a huge and complex forum like this, it's no wonder and no shame that things get discovered, asked or explained again and again. I'm sure there's a lot of people that didn't know this yet and found out by reading your post. So kudos to you.

First time I've seen it. Good to know for when I get mine in a week or so!

was it ever necasarry?
i used regular mini usb on my 8525 all the time

You guys got to be kidding... I couldn't even imagine that someone doesn't know about this already. Mini USB is the standard charger for most recent device these days.
I use the same mini USB (got it for $3) to charge my phone, my camera, my MP3 player and anything that I can plug in. A USB port from your computer have an output of 5Volt... so don't worry about it, it won't kill your device.
Welcome to the Forum, by the way

guys - give him the credit for his discovery. at least it helped me - i didnt know and to me he is the best inventor of 2008!!!!! Way to go abdelbaset0

Lol, this stuff gives me the giggles, personally, ive always used normal MiniUSB cables, ever since they brought out that connection on their devices, but the really funny thing is, when i was in a T-Mobile store once, the attendant genuinly thought it would damaged the device when i said i wanted a normal (miniUSB) car charger to use with my TyTN.... Still Chuckling now.

Sadly, because of reps like that, the various print materials, websites trying to overcharge for a product, and the general user's fear and lack of education....this is the sort of information that a lot of people will probably find to be wildly helpful, even profound.
When my girlfriend got some phone, not entirely sure which one (she's been through quite a few), she thought she had no choice but to use the charging brick and data cable that came in the box. She complained about a low battery one day while in my car. A quick look to see the shape of the port and I plugged in my car charger. She was in shock...and I was equally shocked that a very computer literate asian girl would feel comfortable installing windows but was baffled by the shape of a plug

External Battery charger for TG01??

As per the thread title, I am looking for a battery charger for the TG01. I need one that will simply charge the battery (will need also a spare battery) - and just swap out the batteries as I go. I can't work with an external charger that connects via micro-usb (as I'm having issues with the micro-usb port and can't charge the phone! Therefore need another means of charging ASAP - and will come back and look at how to tackle fixing the micro-usb port at a later stage).
Anyone know where I can get such a thing???
Struggling to do so - so far in my www search....

You mean like this? http://www.ebay.co.uk/itm/Universal...700?pt=LH_DefaultDomain_3&hash=item3a6e594a7c
"Universal mobile battery charger" is what I looked for.
You can get better one's with digital readouts, but that is EXACTLY what I bought a few days ago to try and save my TG01 from a bad wm6.5. Just waiting for it to turn up.

@Scougar: Yes - I managed to get one in the end - off ebay. Hopefully it will arrive before the week is out - as I'm currently phone less!

Not good! Mine arrived today btw... Annoyingly no instructions on what the LED colours mean on it, or which terminal is positive and which negative.
btw.. mine says 850ma on it, so not the full 1000ma, but I can live with that.

I bought this on eBay - can´t paste the link here - look for - 1500mah Micro USB Back up Battery Charger + Cable for Toshiba TG01 TG 01
I am very satisfied when need to power battery out not having power adaptor. However I have totally 3 batteries and purchased also the solar power adaptor with internal battery.

I had the same problem re. instructions - but have got the hang of it. However, it's not a sufficient solution for me. It seems to take an absolute age to power up a battery. I have a spare battery - and even this isn't going to be enough.
I guess it's because of the way I use the phone - with connection to usb keyboard - to write emails...even though I remove the cable the moment the email has been written, it absolutely drains battery resources - RAPID!
I will have to try and get the micro-usb port fixed somehow. I've contacted toshiba to see if - first of all there is any warranty cover on the phone (i bought it off ebay - so not sure if covered or not).
Even if not covered, I'm unsure where to send it - or who can really fix this. Does anyone have any ideas? I am based in Ireland. Do Toshiba have a list of approved service centres??

You will just need to get a higher 'ma' rated charger then (so battery will charge faster).
BTW.. sounds stupid.. but have you tried another micro usb cable (a proper charging cable, rather than just a regular data transfer micro usb one?)

I have tried a number of cables - that had been working at one stage but no longer work. However, they work when it comes to connecting to my usb keyboard.....just not working to charge the phone...
MICRO-USB Repair.
I'm a bit concerned about this - as someone has suggested to me that this can't be repaired - that it's 'terminal'. Can this really be the case????
Seems an awful waste of a phone if that's true....

I'm not sure what "burn's out", so I wouldn't like to speculate, but the repair of the actual 'port' surely wouldn't be that hard even for an amateur solderer? Maybe it's something in a charging chip that's burnt out? Given that you can pick tg01's up for £50+ (I really am guessing here.. I've been drinking).. it probaly isn't worth the cost of a repair unless you do it yourself.

The ruddy thing cost me €200 back then....can't remember for sure when -I think 9 months ago. Just checked ebay and they range from €110-€180. Pretty poor form - if they can't do the job for a couple of years at the very least.
Not sure where I stand as regards warranty - still waiting to hear back from toshiba support.
I don't feel that buying another one is the way to go - if they are flawed in this way. Furthermore, it makes me wonder about investing in a good phone - if they all have a point of weakness in terms of the micro-usb slot. Had a quick look at the nokia lumia at one stage last week....but if I'm using that port heavily (which i am - constantly swapping out between cable (for keyboard) and usb power cable....will the same thing happen?

If you are worried about over working the port, then just get an extension cable or try using a powered USB hub so you won't be swapping it out so often.
The micro usb port design is probably 'weak' compared to the mini USB port design, but it's what we are pretty much every phone on the market is now using. You could also use a USB keyboard.
I would only have considered about £75 for my phone (MODS: I can't sell it , I've bricked it... or as I like to say "I'm between operating systems at the moment" ;-) ) Point is, you can probably get one cheaper than you are seeing on ebay.
I think you are either better off with another phone, or getting a bigger battery, they question is whether you want to invest in the TG01 anymore, or get something else.

How can I use the powered usb hub exactly? I can plug the usb keyboard into it -then run a usb cable between the hub and the usb to micro-usb adaptor that then connects to the phone...is that correct?

This is what is also dampening down my enthusiasm for investing in another phone. It's a situational thing - and I don't really have any other option but to use a usb keyboard (I can't connect via bluetooth).

As regards moving on to a new unit, I don't really want to go down this road for two reasons;
1. I don't think I have got my money's worth out of the spend on the TG01 - and while the work arounds are far from ideal - I am otherwise happy with the phone in principal
2. I fear making another big investment - only for the same thing to happen again (given that I will continue to use micro-usb port heavily
A bigger battery - I don't think is a possibility?? I know there was one oversized battery on the market for that phone - but it came with a new back cover for the phone also - as it was thicker than normal. It was expensive - and it's not really the route I wish to take. What I might do - is buy another battery. Then - with 3 batteries on the go - just keep charging them up on rotation at home.
Mickey mouse approach - but I don't see any other feasible way of handling it.
IF I did get another phone, I don't think it would be the TG01. It served its purpose at the time (and It will continue to do so - although more awkward now). However, I don't think this sort of failure should happen - and support should be better. Very hard to get a hold of someone in support - NO support in ROI - and necessary to mail the phone in to their UK service centre. In addition, just discovered that it's out of warranty.

There are some internal pictures of the TG01 floating around, it might be worthwhile trying to dig those up, and see if you can get a look at the USB connection points, and see if an amateur repair is possible.
EDIT: If you go to the following thread you will find internal pictures It looks to me like the port could be repaired if you have a fine enough soldering iron, or taped it up well enough. (As long as the problem isn't a 'trace' being burnt out... and we assume that the port itself has broken/come loose or needs replacement).

Can someone recommend a good quality external charger
Only a couple of weeks - and the external charger I got off ebay seems to be flaking!
Can anyone recommend a GOOD QUALITY external charger that I could order up - that will work well with TG01 batteries??

Have to say... that one I bought isn't the best quality. connection is 'iffy' now it seems.
Product review: 4/10. d'oh.

I;ve been trawling the net - but they all seem the ruddy same! What would you buy if you had to go again?
Right now - at this moment - the charger is working again - but I spent half the day trying to get it to work up until now! I don't have great faith in it - and if it goes, I'm sans phone once again.
If I could get a reliable charger, I would be fairly happy. I've got into the routine of charging alternate batteries - so that system works (so I can squeeze the outlay on the phone back out of it - before I go and upgrade at a later stage).

The only other type of external charger I could find was this.
So....i've ordered one up....will post back whether it actually does the job or is another piece of sh1t!

USB OTG killed my S3

I'm just posting for brief warning/general info for you guys. When I got to work tonight I plugged in my USB OTG cable which I have been using w/ no issues on both my N7 and S3 since July and then plugged in a 64gb flash drive that I have also been using since launch. When I plugged in the flash drive, I heard a pop, the screen went blank and the phone is totally dead. A quick search showed while this isn't incredibly common, it has happened to several people. Most blamed the OTG cable, but I disceted mine and it had no broken wires and no shorts. I turned up a thread on root wikiz that basically said that it is the power management IC self destructing and there is nothing that can be done to repair it. So, just a heads up if you use OTG-- I am not sure I will use it again on this phone as it seems it is just a matter of time...
Later,
Jason

This happened to me. Verizon will warranty the phone. I wondered what actually blew up in the hardware. I am surprised it hasn't happen to more people, seeing how you really don't have any control over whether it blows up or not.

Sorry to here about your phone. I was jut about to go buy one of these cables.
This same thing happened to my phone a few weeks ago. It went totally dead out of nowhere, I was taking photos at the time.
You shouldn't have a problem getting a replacement even if you don't have insurance.
Good Luck

I have heard stories about that happening, though its not common, it is surprising that its so low considering its random and no one knows exactly what causes it

at least you don't have to factory restore before returning

Sorry guys, I just woke up. Was on graveyard shift last night. Anyhow, the cable was a generic ebay right angle otg cable, about 5" or so in length. I am 99% certain it had nothing to do with the cable though, just a hardware problem. As mentioned above I dissected the cable and it had no problems. I could still use it on my Nexus 7 with no issues. I had the cable plugged in before inserting the flash drive and it was fine until the flash drive was plugged it.
The Root Wikiz thread I mentioned said that someone had sent theirs in to be Jtag'ed thinking it was just hard bricked. The response from the people where he sent it was that they had seen a number of them with the PMIC damaged and that there was nothing that their services could do for them.
My guess is there are some marginal PMIC's out there and that when they switch the port from charge to host mode they just cant take the current and pop. The fact that I made it nearly 5 months using the same OTG cable on a regular basis kind of lends credence to this theory, but who knows. All I know is that it was totally dead, absolutely no signs of life regardless of what I tried.
FWIW I was rooted and running paranoid android, but I have found reports of this happening to bone stock phones as well as any variation of ROM. Verizon did warranty the device. Oddly, the tech told me "I have never heard of this happening" but didn't even ask me to try anything with the phone, he just said that they would ship me a new one for warranty replacement.
New device is here, I'm off to root and unlock! Good luck guys.

Wow, that sucks, but I am glad you got another S3. I have been using this one that I got from Amazon. It has a couple of usb ports and 2 card readers. I have been very happy with it. It is extremely useful when I am at family functions, and everyone has taken a lot of pictures and video. I can grab their cards and pull the pics and video onto my 64 Gig SD card on my phone. People are amazed I can do this with my phone! However, now I am a little worried about using it. I will keep this in mind, and only use it on the occasions that I really need it. Thanks for the heads up!

but i think the s3 is already wasting power and i must charging it after a day.

One day charge is normal if using phone. If gonna use OTG you are overusing and can expect 1/2 day. Buy good cable if want data.

I had something similar happen except, my usb sent a static spark from my oc to my phone. Didn't fry it completely, but messed up something that would no longer dock to pc, dock to car our go into deep sleep.
Wonder if the two issues are related.
Be sure to discharge any static in you usb called before plugging them into your phone.

Discharging is what the battery always does when not plugged into A/C power and turned on, and even sometimes when it is plugged into A/C power (when you get in the top 10% of full it starts going through discharge/charge cycles to keep it within the top 10% of power but never totally full. This prevents overcharging and explosions)
That said:
A sudden reduction in the runtime for the battery under the same average load is almost always the battery going bad.
If you mean the battery doesn't last as long because you now use OTG - those things you plug into the phone need to get their power somewhere. The phone battery is it.
So now you are powering the phone + whatever other things you attach to it. Some of them can drain a lot more power then you might think. You just never noticed much (if at all before) because your total reserves weren't such a tiny amount.
If you stop using OTG devices and your battery capacity bounces right back up to where it was before, then you can reasonably infer the extra gadgets are the culprit.
(if you stop OTG stuff for a few days and the battery still sucks when before it didn't, probably need to buy a new battery because yours is most likely shot.)
Assuming it seems to work fine...
So two choices, right? No accessories and lots of battery life, or lots of accessories and no power to run them with.
well...not really:
It's probably not always possible - but how often do you use OTG near A/C power?
Whenever you are near somewhere you can plug in, the first thing you should plug into your OTG cable (besides the phone) is a USB hub with a power cord.
...and really, if you want to use those power hungry USB hard drives and things like that, then you really can't without taking the stress off of the phone of supplying that power - that hard drive just half spins up like a car that cranks but won't start.
Every crank in that car wears the battery down and beats up the starter when it doesn't fire up the engine. Just like every spin up but not quite read of the hard drive puts incredible load on the S3 to try to throw enough current at it fast enough to keep it happy. Just beating it up for nothing.
Which brought me to what I wanted to bring up for some consideration:
Think about trying to use a powered hub whenever you can as the first thing off the OTG cable, should take an immense amount of stress off of the S3 in making it all work.
Bet at the least you reduce the risk of popping since the power spikes will be much less - that powered hub is a pretty solid buffer for that kind of stuff when you are constantly popping flash drives in and out.
I remember way back when for the Nook Color when some really sharp people made OTG happen out of the thin air - no way Barnes & Noble had that on even a remote list of possibilities when they were ready to throw the device to the masses and see what happened.
If you wanted to use more then the smallest of thumb drives you needed a powered hub. The device wasn't designed for it, and simply wasn't able to squeeze more then a paltry amount of power out in reverse. (but it was just enough to talk to a powered hub...)
Anywhere that you can plug in your powered buffer should contribute to avoiding the problem the OP posted about. The thought experiment (hopefully) growing from this post? How much truth does this theory exhibit?
Edit: Totally missed this post:

Here you say you made an OTG cable, the first post I quoted you in you said you bought one. If you made it, i'd say that is your problem.
The quality of the cable you use absolutely matters. Higher quality parts = higher quality results.
I have a bunch of micro USB cables (as i'm sure many of you do also - ) ... and from some of them I get an absolute night/day result in charging.
Some cables (mostly the ones from the dollar store or older cables) just plain suck. They can't bring enough power from the same A/C adapter as my OEM HTC/Samsung cables. (I have some motorolla OEM cables from around the time of the droid X launch - they are closer to the dollar store cables in quality - haven't tried recent motorolla OEm cables, hopefully they got better or I got a bad batch over a six month period)
Using the low quality cables I can absolutely lose power plugged in just being a wifi hotspot with the screen on, until it eventually goes critical and dies. (this I tend to notice when my pc banished to the corner of nowhere loses all network connectivity) - whereas with the HTC/Samsung cables from within the last two years keep me near full with that being the only difference.
I'd rather have a few good cables then a bag full of POS dollar store ones. That little bit better material, little bit tighter QC adds up to a big difference in the final outcome.

This same thing happened to me when I plugged the same type of cheap right elbow OTG cable from ebay into my brand new S3 (2 days old with about one hour of usage). The cable worked fine with USB drives, a mouse, or a keyboard used alone on the S3. The cable was plugged into a USB 4 port hub with multi-card reader. The screen was off when I plugged it in so it appeared to just be off. Any attempts to power it on were fruitless. I smelt the phone right afterward and there wasn't any burnt smell. Plugging in the phone resulted in it getting pretty warm but not to an extreme yet the battery remained cool. It appears to have burnt something between the battery and lines but leaving the components intact thus causing the excess of heat. BTW the hub/reader is fine. I won't be using that again on my new one but I will be attempting to use a different hub that has been working fine on my wife's RAZR MAXX HD. Just hope this is a very isolated incident and not a bad batch from the retailer.
Edit: The S3 is a blue 16G Verizon model. The S3 was on stock ROM when this happened (not like that would prevent death from inferior circuit protection components).

Were you using a powered hub, or passive hub?
Anyone tried a DAC off the OTG cable?

Don't do it. I've fried 2 GS3s with a UCA-220 DAC over otg.
First time with a regular OTG cable, the second time with a OTG/phone charging cable, the power came unplugged and zap. I'm lucky Verizon has replaced the phone two times.
I think the best solution is to completely isolate the DAC power from the phone power. A circuit to charge the phone with the otg/charge cable and a separate circuit to power the DAC.

Wouldn't use of a powered usb hub remove any power issues? I purchased a OTG cable today.. I had planned to connect it to a powered hub, and run the DAC off that?

Charging stand with storage switch

Hi all,
Have just bought a stand for my HTC m9, it's a sleek looking bit of kit and only costs a tenner which is pretty cheap.
It is designed to work with the phone with no case although there is a removable part which allows the usage of the dot matrix case too, I've confirmed that this works too.
Chances are you may be able to fit some other cases in there but they would have to be slim, the Spigen hybrid does not fit unfortunately, possible to do some modding but that would be down to you.
You can connect this up to your laptop /PC ( USB 3 charges pretty good compared to usb2) it allows you to mount storage via the dock, also confirmed, a standard USB socket is also present on the back which can be used for OTA purposes, keyboard, mouse, gamepads, hard drive etc (untested but should work).
The design is sleek and sturdy, it holds the phone up well, could maybe use a little more weight.
Personally I got it for work so I can mount it and maybe use it as a clock, see messages via the dot matrix case, play music (can change tracks from the matrix case) so far it's working as expected.
Would recommend.
£9.95p amazon UK. Quick delivery, 3 days, no charge.
Edit: @ mod, like a massive melon I've posted this in the wrong thread, can this be moved to accessories please. My apologies, haven't had much sleep,

Yeah, I got one of those too, only to discover that it kills quick charge for some reason. Would not get above 150mA no matter what charger I used.

Don't say that i was beginning to like this, will have a tinker.

Actually, I'm getting a normal charge from mine. I don't like fast charge, it damages the battery. So id rather not do that. Normal charging for me. Just under two hours.

Have just noticed something. Whilst plugged into a charger, this device does not allow USB OTG? What is the point of that? If you disconnect the charger then it works very well but not whilst connected, have not tried whilst connected to a computer / laptop.

Sure the switch on the back is in the right position? I'll admit I haven't played with mine much.

Have tried both, like i said without the cable connected it works fine, selecting it away from OTG, does switch connectivity off, however connecting a cable whether on OTG or USB de-activates it.
I know this isn't an official dock so support is going to be really limited.
Might take it apart and see how it's patched, the power source is more than likely for mounting the phone onto a computer, hence the disconnection.

Display broken -how can I rescue my data?

Hi,
I have my U12+ with dev Options enabled, and last week my display is broken, no chance to made any input with it. Last backup is some moth ago, but I'd made a several week long travel, all pictures are gone, any things I stored on it.
Yes, I know, if I'd made an backup .... But this doesn't help me in this case, afterwards you're everytime smarter....
If there is a chance to copy the data on my Laptop? May sideload TWRP? Is it possible on U12+?
If you have any idea, please help! Also I would pay for it.

When you say the display is broken, does that mean it won't recognize your touch input (per your description), or won't turn on and display anything at all?

Japp, total smashed, just can see some light, but it won't register anything I think -because can't see anything. But light is switched on if I use the Fingerprint sensor at the backside.
:edit: Just zsed a USB-C to HDMI converter -it does not recognize anything.

usb-c adapter to hdmi and usb to connect a mouse

Like this one?
https://www.amazon.de/Adapter-uni-M...ywords=usb-c+hdmi+maus&qid=1596085284&sr=8-10
But how to get further? Because if the Adapter is enabled, and mouse put in, I can't connect the Laptop for transfering the needed data.
edit: bought one from Fitfort with 3 USB Ports, and works fine. Thank you very much for the hint!
Nevertheless I'd repaird it afterwards with new Display and new (unfortunately the blue backcover isn't avaiable anymore, so I have now a black one) Backcover.

Where did you bought the screen? I need to buy one too but can't find an original anywhere

I'd bring in it to a local reparation center (free, not from HTC itself), cost were (with original spare parts, and I think they are thrustable, because they also do jobs for German gouverment) 130,- with guarantee. Not to much, and I'd can wait for it.
They told me that it is hard to find original spare parts because of HTCs history.
