Hardware help - Hardware Hacking General

Hi guys i have TL W-9208
a guy gave me because its battery connector pins are broken and the phone wasnt opening..i tryed to fix it with kalai(in greek) its soldering iron i think(this is: http://cdn.instructables.com/F8Q/NF5Q/0DIEWP8729Q/F8QNF5Q0DIEWP8729Q.MEDIUM.jpg), also i putted some in battery to make better connection
and the result is:

the phone works but sometimes after moves it shutdown..how can i fix this? its because it has bad connection or what?
Does anyone know where to find this battery to buy new?
also can i replace the battery connector with battery connector from another phone with 3 pins?
Thanks in advance

Well find alternatives on ebay or use that battery. Use hot glue to secure battery temporarily if loose connection occur. Remove useless app and less frequent charging will prolong its life or contact any eletronic/mobile shop. Hope this helps.
Dude it happened to me. I got a symbian phone whose battery was 7 yrs old but still it worked briliantly. Although i find a battery but its size was small and i used hot glue to firmly held it. It worked well. But last year it got stolen. I miss that unique phone. It was preloaded with band &oulsfeng amplifier. Checkout samsung SGH-i450 on internet.

Qtek 9100 charging problem- NOT battery issue..please HELP !!!

Hello Gentlemen,
I have charging problem with mu Wizard Qtek 9100... its not battery issue I have 2 working batteries...
The phone starts only when the charger is not pluged in..
Otherwise RED light is shown and the phone refuse to start so I need to remove the charger and the battery and then put the battery back so I can start the phone...
When the devise has started already I can plug the charger but the Windows is not showing ORANGE light and is not showing charging....
The device acts very wired and is turning off with no reason...
This happened when my charger burned up while charging my device...
Now I have no sound,the device is SIM locked and is turning off sometimes for no reason....
I believe it is a hardware problem I guess I need new mainboard?
Please advice if this could be a software issue....
The device is G4 IPL/SPL 2.26.0001
Please advice,
Thank a lot...

Battery problem
Hi,
I know old post, but it may help somebody.
It is possible that your windows has switch off the battery charging circuit for some reason.
You MAY be able to get it working with the following trick:-
You need 3 x 1.5 volt AA batteries, some wire and 2 pins
You need to join the batteries together in series (i.e. end to end)
Next make a negative lead from the negative of the battery pack to one of the pins.
The make a positive lead in the same way.
Open the battery cover of your Wizard.
Connect the USB charging cable.
Put the negative pin you have just made into the gap between the battery and the charging pins in the Wizard - MAKE SURE YOU ONLY CONNECT IT TO THE PIN NEAREST TO THE USB PORT.
Now comes the tricky bit - take the positive pin you have just made and touch it on the charging pin which is NEAREST to the power on switch.
If all goes well the charging light on your Wizard should turn orange indicating that it is charging.
You might have to try this a few times, I was never sure if you had to keep the external battry connection on for any length of time or just a quick connection would do the trick. I suppose it depends on the state of the Wizards battery.
This is NOT my work! I do not want to take credit for something that is already documented on this site as it helped me get my battery working again.
Regards,
John
thanks a lot!
saved my wifes phone. Is this problem (happend twice already) something that I can address with a new rom, anyone knows?
I also have the remove the battery go back to Feb2006 issue. Device is off warranty by a few good years. Is it something an experienced electronics person could try (without destroying the phone that is...)
Cheers
V.
Worked for me too
I had just bought a new battery for my Qtek 9100.
This one:
sku.23974 at dealextreme.com
My 9100 had been dead since 2006 (because the battery was dead ...)
And i got a new phone.
but i tought it was to good to throw away, so i bought the new battery.
But i did let it run out of battery, and it would not take the charge.
but this trick did the job
Thanks
Hi all,
Just wanted to sign up to say thank-you - I chanced upon this forum while seeking a solution to the same problem.
I'm happy to report that the 'jump-start' works perfectly!!
I actually used the slightly different method, described in another thread on this forum:
Take a USB-to-Mini B cable. One that you won't need ever again.
Cut the Mini B end off and strip back the outer casing. Inside is a wire mesh and within that a foil lining. Pull these both back.
Now find and strip the black and red wires. The wires are thin and this is a fiddly job, especially if you have large hands, so this works best if you screw the exposed wire strands up into little balls.
Remove the battery from your Qtek 9100 (or whichever model it is). Pay attention to which pin goes to which contact and so identify which ones are the positive and negative contacts on the battery - It is described above in Heinkeljb's post.
Now, plug the USB into your PC (which should be switched on and running) and connect the black wire to the negative (and red to positive) contact on your battery.
Hold for a good 30 seconds.
Now reinsert the battery into the phone and attempt to charge.
You may need to 'jump' your battery a few times....
Once again, many thanks to teh lovely people here for saving my beloved Qtek 9100!!!!!

[Q] broken micro usb port (direct charging)

hi,
well i managed to snap my charging port inside my hd2 and well, i get nothing when my charger/usb plugged in... im wondering about directly charging the battery whilst being able to use the phone at the same time... ie having the charger contacts on the phone and battery at the same time... wondering if this is possible as i dont want to damage the battery/device...
also what would i need to hook to each contact? i know positive n negative poles but is what the middle contact??
any help with this would b much aprieciated... thanks
luke
p.s i couldnt see anything that would help me in the other forums i looked at
Yuor best bet is to buy a 2nd battery and a battery charger from ebay then use 1 battery whilst the other charges.
Its not to expensive to repair, if thats the only fault
i see ur from england too so do u know any cheap places that can repair this fault? links if possible... thanks
any joy? I found the following two websites but am now weighing up my options.
htcphonerepairs.co.uk/HTC-HD-2/Charger-Port-HD2.html
simtekworld.co.uk/index.php?route=product/product&product_id=529
I have a similar problem. Don't know how or why but for some reason it suddenly stopped charging on Friday night. £50 to get it fixed is a bit excessive.
I wonder if a battery charger might be a better option?
EDIT: the answer to my own question (so far, at least) is "YES". Bought a cheap charger and battery off ebay and both are working well (touch wood). It's a pain in the butt having to change battery and not being able to charge it in my car but it's also quite useful having 2 batteries.

Problem with USB!

Hello,
I don't know if it is the right place to post, but because I think my problem has to do with the software.
A few weeks ago, my HTC touch HD stopped being charged when it was on. No signs that USB was connected, nor with the computer or the charger. Still though it would charge when the phone was off, so I postponed to fix it back then. When I tried to change the ROM to the latest one(this is the ROM I have installed http://forum.xda-developers.com/showthread.php?t=809477), I couldn't and even after I connected the USB the screen kept showing "serial". Things are getting worse, now it shuts down without any alerts, especially when I watch youtube videos or browse the internet...
What do you think is the problem and what should I do? Can the device be fixed? I dont want to lose my beloved Blackstone
Thanks in advance!
the blackstone usb port is a known weak spot, maybe it really just quit on you and you should replace the mainboard. another possibility would be that the phone is fine and the battery is broken. the easiest way to tell which one it is would be to charge the battery directly in a docking station or external wall charger or get a new battery for it and try and charge it in the phone, see if it behaves any differently than your phone does now. if you are lucky, you can get your hands on either one from a store with a good return policy, so if that does not do the trick, you can return it as used only once and get your money back.
sadly, if this didn't help, you might want to say goodbye to your beloved blackstone, because replacing the mainboard is a lot of work and might become quite pricey for a device that is hardly worth 100eur these days.

Thanks for your answer!
I person I know has a working blackstone and I will ask him to lend me the battery. I am not good at soldering and I wouldn't bother with changing the board at all.
I cross my fingers and hope it works, because I loved this phone so far, it could do anything...
Got the battery from that guy, tested the phone and still it wont charge...
too bad, then probably your usb port and/or mainboard is fried. if you want to hold on to the phone, get an external charger, like a docking station with 2nd battery charger, kinda like this (not this exact one obviously, as it is for the galaxy s2): http://www.ebay.com/itm/Dual-Sync-C...AU_MobilePhoneAccessories&hash=item2a16087f53
or a direct battery charger like this one: http://www.ebay.com/itm/2x-1530-bat...AU_MobilePhoneAccessories&hash=item3cbebda52d
Once again thanks, but I have already have made my plans!
The phone itself is far from broken, so I am going to make it an entertainment device, for home use. No battery. Just a 3.7 DC transformer, acting like a battery. For the move, a simple nokia dumphone does the work!
Going to get back on you when I complete the project.

Before I throw my G1 to bin - charging issue

Hi,
I checked many threads with no solution so this is last chance
Did someone recover the phone from no charging issues ? Even if this is hardware.
I have mine old G1 and wanted to give it a second life. I noticed that it does not charge when off (no led) and when on (led red >orange, status on the phone "charging"). It only charge in fastboot mode (led off). I got new battery, charger etc.
I saw it is common thing but last posts are like from 2010. Does not help: wipe battery, changing radio, battery or charger.
It is 1,6 superD.
Maybe it cost low to repair if it is hardware. How the hell it can be it charge in fastboot?
I would get along with it if it was bricked but in this case - it works but does not work if you know what I mean.
Ciao
try cleaning out the usb port with like a toothpick and some rubbing alcohal, my guess is its hardware and the pins to charge normally are damaged but the pin to work in fastboot mode are still intact. if this is the reason why its bad you would either need to solder a new port to the daughterboard (really tricky unless you are a master @ fine soldering)
or replace the whole daughterboard. which of course is very hard to find by itself. more than likley you will have to by a broken/used phone off ebay (maybe as cheap as 10 bucks) with a working usb but whatever else broken and swap daughterboards, pretty easy to do.
but maybe double check if its firmware/software first by reflashing new rom or doubtfully a new radio/spl
Sent from my HTC Vision using xda premium
Thanks a lot for the reply.
Indeed buying something with broken screen would do. My soldering capabilities ends on swaping capacitors, far away from micro soldering
Anyway, I tried all other things you have mentioned.
Cheers!

[Q] Battery Mainboard Solder

So there's lots of questions about bad battery life but haven't found my issue in searches - altho I suspect my issue is a factor for many to some degree.
N4 took a 4' to drop to concrete. Screen cracked. Replaced screen w/no problems. Ran fine for a while on stock 4.4.4. Lollipop comes OTA practically zero day and since the N4 isn't my primary phone I upgrade to play around. Shortly after 5.0, the battery drains and shuts the phone off. I charge it overnight, pull it off, battery is dead, phone shuts down. Will stay on and operate fine on wireless charger but powers down if not connected. Pop off the back again to make sure battery connector is snug and reassemble. Now I've got red light of death. Get Google logo and can boot to recovery options but it just cycles. Disassemble again and ultimately find that the battery pins from the mainboard and their little black housing have come off at some point. Try to solder it back on but there's chips on the back side and there's just no room to get the solder on and pins reconnected. Not w/my skills anyway.
My main question is, has anyone successfully reconnected that annoying mofo? Thinking about skipping the connectors and just soldering wire straight from the battery to the board. I don't see anything in that connector that would be a problem if absent, but any warnings I should know about? Other workarounds?
This is not mission critical, just principle/spite.
Repaired?

So were you ever able to get the connector solder back on? I think mine break because it was to hot when I was removing the battery. My nexus 4 shutdown on me, my battery was expanded. I was wondering why my screen was being pushed out. I wonder if Android 5.0.1 is causing phone to run to hot. Never did this with Android 4.4.4. Hope the connector can be fixed. Maybe I take it to a solder shop.

Not yet. I pulled the connector back off and cleaned everything up. I found that even very small gauge solder is too sloppy for the 4 small connections. Not to mention there's chips on the back side so you can't linger too long with heat. So my plan is to try again with some conductive ink and/or gel. If that doesn't work I'm just going to use wires to bridge the battery right to the board. Haven't had time to work on it but I'll follow up here when I do.
Did you get a replacement battery? Lithium batteries can swell because of overcharging. There are definitely more than a few N4 owners who had the same issue. A replacement battery won't solve that problem but it could be more tolerant of it, for a while - and depending on if it was "user error" or a fault in the phone's overcharging protection circuitry. Don't go to the trouble of having someone solder the connector back on with the old battery.
