So.. here goes my problem..
Got my Qtek 8310 three days ago, and the very same day I got it, decided to upgrade from WM5 to WM6. However, the battery charge meter gave me wrong info about the battery charge percentage, and the phone battery died just after I formatted the BINFS and re-setted the device in TeraTerm.
The device still powered on, after each USB cable re-insert, but died, after 5-10 seconds. After a couple of attempts, the phone didn't turn on at all.
Did some info search on the web and found out, that my battery fell to an critical voltage level. Li-Ion batteries require a certain voltage to even be able to accept a charge.
As I got an non-original battery (Sanyo ST26C) I suppose it is poorly designed and doesn't have good under-voltage protection (I have read about other HTC models (e.g. Wizard) having this problem as well), so the battery dropped below these limits and phone now identifies the battery faulty and doesn't let it charge. This is for consumer safety, because attempting to charge damaged Li-Ion cells can be dangerous, as Lithium is known to be able to catch fire/explode.
So the phone doesn't let to charge the battery in any way (1amp wall charger or USB cable).
Anyways, I tried to jump start the battery (charge with bare wires) to give it initial charge and... it worked. However, there goes my main problem: As soon as I insert the battery which has the initial charge, the phone starts immediately and boots to a bootloader (as there is no OS, formatted BINFS) and the the phone does not charge while in bootloader.
Then, I tried to turn off the phone: Hold down power off button for 5 seconds - phone turned off. But as soon, as I release the button, red light flashes once (as it does everytime, when you try to turn on the phone, it's normal) and then orange LED comes for a second, indicating a charge (as the battery is no longer considered faulty - phone lets it to charge), BUT then phone starts again to the bootloader and it somehow prevents further charge.
So: as soon as I release the power off button, after the phone has shutdown, it starts again, everytime, and soon the battery dies again.
My own thoughts of solving this:
* Get a fully charged battery from a friend, install the windows on the phone, and then charge my own battery (I know noone, who may have HTC Tornado, will be hard to get);
* Buy some standalone dock charger, which can charge batteries directly and charge the battery happily (haven't seen any around yet, so will be really pain in the arse, to get one);
* Charge battery with bare wires for an extended period of time, to give it enough juice to install windows (which I strongly doubt, as battery damage could occur);
Any other ideas? Ideas and comments, from people who know, or had similar experience is more than welcome. Looking forward for answers
Its funny. Reading you I've realized what people tell me about "I make a question and I answer it myself" So... You have the answers my friend. For options 1 and 2, use E-Bay. As a matter of fact, there is an aftermarket charger in ebay that charges your phone and a spare battery and it includes the spare battery when you buy the charger. I believe it runs for under $20.00. For option 3 use some wood cloth pins(those used to hang cloth to dry). I would say with at least 2hrs charge you should get a good 50% charge on your battery, enough to flash your phone.
Edit: Here is an Ebay Search. But, keep searching till you find the one that includes the extra battery. Chances are your battery is no good or won't last you very long.
Good Luck!
Get a new battery man, these li ion batteries, are no joke, especially the fact that they are made in China/Taiwan, I myself had used a tornado battery even till the days when the battery has bloated and cracked the back cover, when a single charge could not even last 4 hours.
Those days, were like having a timebomb in your pocket, ended up I got mysel a new tornado at a price cheaper than a replacement battery.

Well yes, I have some suggestions, but I am also expecting others to have some, too. And by sharing the knowledge, maybe I could prevent myself to spend more money on this issue

The main problem with e-bay is... my country. at least 80% of the items, don't ship to my location.

Thanks for the suggestion. The main reason why I am in serious doubt about this option, is that standard chargers usually have some sort of regulators and monitors the charge, prevents from overcharging, etc. But on the other side, USB charge output is only 100 mA, so it couldn't be that bad if you think about it

Well, the fact, that it is manufactured in China actually says nothing Many companies choose China to manufacture their products because of low costs. And the most of electronics is manufactured in China and other Asian countries.
Anyway, before getting myself an new battery, I would like to try resurrect this one If this won't last long for me - no problem, I will get an new one. But until I'm convinced enough, it's a waste of money, which I don't like doing
And one more thing.. maybe someone knows a way to keep the phone power off?
Because as I said earlier on, it's charging only when it's turned off, and not in the bootloader. And problem is that, as soon as I put the battery, it starts-up the bootloader.
Get a desktop charger perhaps?
Or if you are adventurous enough, mod the USB cable, and charge the battery directly, only if you know what you're doing, and only if it works

Well.. thanks for the answer, but we've already discussed this option and now I am asking whether or not, someone knows a way to turn off the phone and keep it turned off (prevent from self startup) while the phone has no OS (got formatted BINFS).

I've already done that, and yes, it works. But I need someone to confirm, if it is safe enough to charge the battery for an hour or two.
Have anyone tried that?
I don't think that it's very safe. But I was having a similar problem, and I just left the phone connected to the power cable, and even though it seemed like it was not charging, it apparantly was.
Or you could just get a new battery. On expansys I saw a new one for ~$20.

Well..
With a modified USB cable (bare wires), which got power output of 100mA I have charged battery directly for approximately 3 minutes, and the phone turned on, and was operational for 4-5 minutes until the battery died again.
And before that, I've tried leaving it on an mains charger, which got power output of 1A (1000mA, 10 times USB). I left it for a hour or two, although no led was showing up to indicate a charge. The phone didn't event turn on after this 2 hour "charge".
And the reason for this is explained in my first post. Will try to leave it charge over a night, though, expecting for a miracle

But new batteries usually come empty, so it's no use to me. I have also explained why, on my previous posts.
So before buying an cradle charger, I would like to find out if these budget-friendly solutions will work:
1) Find out how to keep the phone powered down (because it's the only moment, when it truly charges);
2) Find out if it is safe enough to charge battery with bare wires for extended period of time (1-2 hours);
Just came up with another idea. Searched the forums and found a very similar problem to mine:
fritzgerald said:
For some odd reason my wizard likes to say the battery is full when its actually dead and that it's dead when it's really full. Well a few days ago I was reflashing to try and take care of the issue and it died during the middle of flashing. It would only goto the bootloader screen and would not charge. Well I decided I'd post a few pictures of my recovery technique utilizing my wife's phone. Cat5 cable striped at the end and twisted to each of the positive and negative battery terminals and the Blackberry's battery put it so I could use it to power the wizard.

So.. I've got a Sony Ericsson w810i, would this technique work? The w810's battery is Li-Polymer, 900mAh 3.6V (although some sources say, that this exact battery is 3.7V..), compared to Li-Ion 1150mAh 3.7V Tornado's battery.
Voltage seems suitable..
Haven't got any answers to my previous posts, so I tried.
The trick worked, Sony ericsson's battery can feed HTC Tornado perfectly. However... got another problem..
Here's how I wired it up. The positive wire takes two contacts and the negative takes another two aswell. The ends of the wires are then connected to the sony ericsson's battery. Phone starts, and boots to a bootloader. Everything's seem to be perfect.
Then I plug in the USB cable into the computer, the other end to the phone. Phone recognizes the cable and puts label "USB" at the bottom of the screen.
However, there's something wrong with the connection.. TeraTerm fails to connect and Update ROM utility fails, too, with an "cannot connect" error..
After that, I have tried using the original battery, with no wires attached, just plugged it in (gave it an initial charge again) and the USB worked without any problems: TeraTerm can connect.
So the problem seems to be in wiring.
I have tried to connect the wires in different random ways (crazy, I know), but only one alternate way did worked. Although, phone did heat-up rapidly at the area, where it says "HTC Innovation" and phone's display showed "USB" even if no USB cable was connected.
So.. looking forward to some thoughts or any knowledge, of why is this happening, wiring schemes, or any other suggestions..
FINALLY! SUCCESS!! I've connected the wires from the sony ericsson's battery to touch only one pin on the phone, instead of two, as shown in the picture. The phone didn't turn on, as I've tried this before.
But then remembered that the same pins charge the original battery, so inserted the battery and VOILA! Phone turned on to the bootloader and the USB circuit wasn't blocked no more! Flashed the phone to WM6.5 now successfully and the original battery is charging, as I write this post )
So, if anyone got HTC smartphone dead, while flashing, let me know, will try to help you out, since I've walked through this hell myself
Thanks goes to karhoe, for an excellent guide for flashing, also dharvey4651 for an excellent guide on installing vista's USB drivers (got new PC, upgraded to vista) and last, but not least - the whole XDA-developers community for helping me out
1A Wall Charger Works!!
I've had the same problem discussed above. I was trying some of my own 6.5 ROMs, which by the way were getting stuck at the initial boot screen itself. Due to some unavoidable reasons and circumstances, the phone freely was left to itself at this exact state, untethered to any power source, for extended periods of time, during which it slept and refused to wake up again, all my pleadings going in vain. And when it did boot, it went into the tricolor screen conveniently and switched off in ten seconds. I turned to the net for help and found that any charger with rating above 1A would help in giving it the required juice. I didn't want to waste any of the 6 USB cables I have.
I got the original charger, which is an 1A charger, after 2-3 hours of searching my room (Hey, Don't be too hard on me! In the end, I got it, right? Actually, I use the PC for charging, and a smaller 550mA one sometimes-- both didn't work this time) and then, when I connected it showed the screen again. But this time, I found that it was capable of running it without the battery being present.
So, all I did was I kept the charger connected to it with the phone switched on in the tricolor mode and with the battery inside. After half an hour, I tethered it to the PC and flashed a proper ROM. And Voila!!! IT WORKED!! It was 2.45 in the morning!!
I guess the power from the 1A charger is enough for the phone to run and charge it too which is not the case in the 550mA one and the USB cable.

Glad to hear that it worked for you Unfortunately, it didn't for me (as I only have an after-market charget, not the OEM one, although it is 1A), so I had to search for alternative methods.
So, received my TF700T in the post today. Got all excited, went to start it up, and nothing....
Has been on charge for 3 hours now, and I still get nothing when trying to start it up.
The orange light near the power button is on, indicating the battery is charging, but no matter what I do, whether I hold the volume down with power, hold both volume buttons and power, it won't start up / boot.
The strange thing is, when I first tried to start it up, it wouldn't load, so I plugged it into power, and I got the ASUS post screen, then it turned off almost immediately (I presume as it had insufficient power). Since then, I have not even been able to get the ASUS post screen. If I hold the power button for 10 seconds, it will vibrate after 10 seconds, then nothing happens.
I have tried all the volume + power buttons described above, as well as trying to reset button.
Is the tablet DOA? Any suggestions for ways I might be able to get it started?
Try putting a pin in the pin hole above the HDMI.

Tried this already, and just tried again now. Nothing!
Its weird that if I hold the power button in for at least 10 seconds, at about the 10 second mark, the tablet vibrates, but nothing happens.
The charger light is now green on the tablet, and still nothing. Has been on charge for 5.5 hours now.
Unfortunately, It sounds like a DOA. It happens. Good to know now then 6 months down the road.

Exchange it.
Haha, good old DOA. Mine took 6 weeks and the store gave up and just gave me store credit.
Return it!
I had exactly the same: on first boot it turned off after splash logo and I needed to use reset button to restart again.
long pressing just makes it vibrate but nothing more
And when it started, it crashed and rebooted all the time. Sometimes it went black and I had to reset it again
My replacement works perfectly, so yes it's a semy-DOA

JB have the Infinity in stock now, so you can use your JB voucher towards that if you wanted
Thanks for the replies all, I'll send it off this morning and update once I hear back from the seller (the joys of international dealings).
Mine bricked with the same exact symptoms after a week. Worked flawlessly up to that point. Waiting on the replacement to ship...

hi,
I was gonna open a new thread since my problem is based on charging but this thread pretty much is for the same use.
I got my tf700t yesterday through a friend visit from US. It has been nearly 2 weeks since he got it and he never charged the tab since he wasn't much of a user. So yesterday he brought it to me (i'm in TURKEY btw) and the tab was working pretty properly. But it's charge was near %4 so i plugged it on to its dock and plugged the usb charger to the dock via my PC. I just saw on the tabs screen that its charging so i left it there for like 12 hrs since it was its first charge. Then after nearly 12 hrs later this morning, i disconnected the charger and saw that the tab was off. I tried to turn it on but just like cjhod1 says, I got the ASUS post screen, then it turned off almost immediately. Different then cjhod1's case, no matter i plug on the charger or not my battery led near the power button is off for all times. So i guess this means it doesnt charge at all which was operating properly 12 hrs ago.
Strangest thing is my dock doesnt charge either. I tried every possible combination but couldn't manage to get it done. Even more strangely, after a one hour charging with nothing indicating it's actually charging (the orange battery led is off for all times) it managed to get a %1 of battery charge and opened. It managed to stay on for 10 seconds and then shut down once more for all.
It seems like a battery problem but what are the odds to lose both dock's and the tab's battery after one charge. And now that i'm in Turkey, and as far as i know, asus doesn't provide an international gurantee but only for US, i can't seem to get any service here. Unless any solutions to this matter occurs, i will have to ship it to the seller that i got from the Amazon. Every suggestions or helps appreciated. Thanks in advance.

The tablet CANNOT be charged via a USB port! Use the specific charger that came with the tablet. This will deliver the necessary 15V to the system to allow it to charge.

then how come i managed to charge it the first time i plugged it to the PC? And even if so, that is not any handy at all. I will have to carry not only the usb cable but also the adapter with me for all times to be able to charge the tablet. That is not an issue for ipad as far as i know.

It's not a big deal. It charges to full within 2 to 3 hours. Put the darn usb and adapter in your bag pack along with your tablet. It's not like it's a size of a water bottle or something. Charging through the usb is not ideal since it trickle charges and will take forever. Charge it through normal means first and see if it can hold a charge through your everyday use. If it does then your good to go. Then try charging again through pc. Honestly with the tablet keyboard combo you won't have to worry about not having enough battery life to last you the whole day regardless of what you use it for.

Hi Bezendra, did you get it to work? I have the same problem. I'm in Vietnam, and whilst the tablet charges just fine, the dock seems totally Dead on Arrival and doesn't charge (no light, nothing). Warranty isn't really an option here so I need to troubleshoot this exhaustively before giving up. Did you discover the problem?
Speculation: I remember a friend who visited here once, and their externally powered USB hard drive didn't work in certain houses. I think it depended on the type of voltage regulator in the house. Did you discover anything similar?
