charging circuit on wallaby - MDA, XDA, 1010 General

Can anybody explain to me why the wallaby i have after a failed radio upgrade refuses to even show any lights for charging? The only time i get a light is if i leave it unplugged for say 15 minutes and then plug it back in, i then get a red light for about 10 secs and the wallaby boots. Its really bugging me why this is happening, i am wondering if maybe the charging circuit is damaged along with the radio?
I am not really interested in getting the thing repaired but it would be nice to be able to use this as a tom tom gps without having to install and set it up everytime i plug it in, in my car. cheers

Charging Problems after 2003SE rom upgrade

I went away for xmass, and the last thing I did before leaving (this is stupid i know) was to upgrade my XDAII to 2003SE 2.02 rom.
I brought only my USB charge cable because i didnt want to carry too much.
Now, when I plugged it in to charge on my PC it said charging and the light came on as usual. However, it seems it wasnt charging. I left it overnight expecting to have a charged unit, only to find it completely dead the next day.
Now, when I plug it in, the charge light comes on RED for about 2 minutes, then the unit comes on from a hard reset and shows both charge levels at ZERO.
It stays on for about 10 minutes pretending to charge, but only the backup battery charges, the main one doesnt charge at all. Then it goes off totally and the light goes red again.
If I turn the unit off while it goes red straigh away and wont come back on.
After a few minutes it comes back on and pretends to charge again. The Backup battery reached "100 %" but the main battery will not charge. its still at 0% and wont charge.
Ive connected it to a 5v2amp psu as it requires but this was via a powered usb charger so using the same lead, not the official cradle.
Im worried there is something wrong but dont have access to the cradle.
Has anyone else ever had experiance of a total discharge state on an XDAII ?
UPDATE
I travelled 50 miles today to get to the nearest charge cradle for an XDA2, put my battery in and it charged fine. I put it back in the XDA and it worked. However, when I got home I plugged it into the USB charge lead, and it came on and said charging again, with the yellow light and all seemed well. I left if for a bit and the battery was then dead again with no charge and back to showing the red light. it wont come on at all now.
This is the same lead i used previously and the only change is the 2003SE rom, has anyone else had a problem charging after doing this rom upgrade? Can I revert back to 172 ? how? help please.
Please help. IM screwed unless I can find a solution, has anyone got any idea?
Dude, I have the same problem on my 1.72 version. I have (of course) dropped by xda2 several times on the floor, but it works charging from the cradle (which again has a adapter connected to it) but not from my brand new USB sync+Charge cable. I have also tried another cable and even on a different PC. Only thing that happens, is that it says it is charging, but nooooo... it's all flat after a little while. It's as if the cable uses my XDA power to change the PC instead of the other way around
It's funny. So now I have to drag that big-ass charger along with me to work every day instead of that neat little USB cable.
Life is unfair!
As for your problems, I can only say that you're not alone.
Hi, thanks for the reply.
I havent ever dropped mine, ive taken good care of it, so I dont think that is the cause. It does sound like the same issue however, I dont have my cradle here to test it though, just a usb sync+charge cable.
Does it work with the charge adaptor and psu alone? I mean the little thing that goes on the end of the mains psu to connect directly to the XDA without the cradle. How about on the cradle without the PSU plugged in?
I think this may be a hardware fault that needs repair, so its off back to o2 for mine if it is, you may find they would repair yours too.
Anyone else got an idea?

With my charger alone, it charges perfectly. In the Cradle with the charger connected, it works too. I havn't tried to use the cradle alone using only the USB cable to the PC.
I think I might bring it to the repair-dudes when it's so trashed that it is not working at all Until then, i will keep on using it.
I have exactly the same problem. i am not sure if it was because of the upgrade, but this is what happened to me, I upgraded to 1.72wwe from the factory 1.66wwe and it was working fine when I noticed that sometimes when it was charging after pulling out the plug, the unit will display 0% charge from the external battery and then after plugging it again the power is at 100%, It happened twice and was ok again, I presumed it was just a glitch from the system and promptly dismissed it as such. After a week, it was hardresetting everytime i got it out of the plug. I brought it to the service center and they replaced the battery (it was under warranty) It was working fine then I upgraded to 2003se the unit was ok for about 3 days then i noticed that the unit was loosing charge and hardresetting everytime. I brought it to the service center again and they said they replaced the motherboard this time and was back to 1.66wwe. So far its ok and working fine.

fix wing

my t-mobile wing wont turn on, im guessing it has some kind of software problem...does anyone know where i can fix it?
give more detail
-the phone/battery wont charge...
-sometimes i plug in the charger and the orange light comes on, no matter how long i leave it plugin in (up to 24 hours) it does nothing
-when i try to turn the phone on it wont turn on, and if it does it turns of as soon as it turns on
have you tried a different charger? what about a different battery?
what does it do when you plug it in to your computer with the usb cord?
all chargers do the same thing, i havent tried a new battery yet because i went to a t-mobile store and the lady said it probly isnt the battery...but i plan on buy a battery tho....when i plug it into the computer its keeps the phone on for a few minutes then it shuts of
have you tried to hard reset?
hold down the 2 soft keys - - and press the reset hole.

Bricked G4 not (!) again: Charge LED does not light on power-connection

Hi there,
I have a special question to my G4 witch i do not get in operation anymore: The Problem is, that the device does not turn on, independent any keys. Either the ON-Button, Soft-Reset, Hard-Reset i do not get any of the "normal" screens. The display does not light.
Additional, the red power-charge-LED does not light when i plug in the USB-poer-supply. The same, if i disassemble the battery and plug the G4 to the power-supply...
The device has not been used for a couple of months. The last action a Upgrade to WM6.5 that worked definitively fine for a while.
Has anybody an idea? Or happend before?
Thanks in advance
Ernie
i think it`s easy
hey .. i doubt you have a problem with your g4 phone, i think you have a problem with the battery. since you left the batter inside the phone for alot of months and you didn`t use it, i think the battery is super dead, so dead, that the g4 cant power off and go to charge mode. 1 : you could try letting it charge more, like .. 1 hr plugged in , orrr , you could find an universal charger, which charges the battery by touching it`s + and - with it`s pins and putting electricity in it. (sorry for the bad explanation but i`m from romania). I think one of them two should work, if you know some other friend who has a working g4 just try with his battery. Good luck ! ^_^
Thanks for your reply.
But it happens without (!) the battery: If disassemble the battery and connect afterwards the power cable, the red LED does not flash, and no key has a function. As Soft-Reset "switch" and Hard-Reset (2-button on the left plus Soft-Reset-Switch)
First i mentioned the same as you thought...
Has anybody an idea what can be done here?
Thanks in advance.
Ernie
I'm encountering this same problem. I let the device charge over night with no luck. It will not power on at all. The battery was working fine last week. its completely dead
My Universal turn on the red LED for a seconds and after that do not charge and do not turn on. Have you find any solutions?
Thanks
exactly the same problem here on touch 3g
i got my touch 3g in Jan 2009 in Shanghai,China. Now i'm in singapore.... it's bricked, i didn't do anything wrong, it's not dropped on the ground or into the water, yesterday it was fine, but this morning i just found that it's power off. plugging in the power cable , and i won't see the orange power led. it's completely dead, soft reset and hard reset can not be initiated, because it refuses to power on.
i'm going to htc care center at harbourFront next weekend ...

You’re in the wrong section this is the Wizard forum.
I use a universal charger. Its one which takes the battery not one which plugs into the phone ...
whenever I let my phone run flat I leave the battery in the charger for a couple of hours then put it back in the phone and connect the phone charger. Once there are enough electrons whizzing around in the battery there's enough power to drive the IC that manages the charging in the phone ...
if the battery is too flat it won't even open the gates for you ...

[Q] TP2 wont charge but LED is amber (replaced charger, battery and usb)

Good morning all, :laugh:
I have this weird problem with my HTC touch pro 2...
A couple of years ago i bought 2 of these phones and i actually never used them until 2 weeks ago. (so brand new)
This, because i decided to flash them with android NAND ROM's which seemd to be working fine up until one point where i got this issue.
Some background info about the phone:
Both of them are HardSPL unlocked, have WinMo removed and instead have Anrdoid 2.3.7. installed. (which is working fine btw)
At first both of the phones seem to run fine and both of them where able to charge.
After a week of using the phones one of the phones stopped charging. (i tested some VOIP app from Aastra)
When the phone was powered on and the charger was plugged in, the Amber LED was lid but the battery was still draining... altho in the Android menu it stated "AC - adapter, Charging".
Because the charger i use is the original HTC charger which is brand new and so is the USB cable my first thought was.. well the battery could be defective since it has been in the box for some years..
At this point i changed the battery from one phone to the other to see if it would charge, but no luck still the same issue.
Then i replaced the AC adapter and USB cable with the ones from the other TP2, since that phone was charging fine...
Also no luck, the TP2 was still showing a Amber LED but did not charge at all.
After this i tried plugging in de USB cable in my PC to see if the PC would charge it, but as i expected, again no luck.
Then is switched off the phone and plugged in the AC adapter, the LED goes to Amber which indicates charging.
But now the weird thing, when i unplug the cable the LED remains amber !
And then the even MORE weird thing.... when i at this point remove the battery, wait 30 seconds and re-insert the battery the LED becomes amber right away !!
And when i trie to turn on the phone it does nothing, there is no respons at all to pressing the power button...
Just that amber LED....
Then i tried removing the SD-card and SIM, left the battery out for over an hour and tried to re insert the battery, but still the amber light goes on The AC-Adapter is not plugged in at this point !
At this point i was not sure anymore what to do, so i disassembled the phone to look if there was some bad / loose soldering on the USB plug.
But sadly enough i could not find any bad or loose soldering points, i also was not able to find any burnt or other bad looking circutes.
Then i reassembled the phone and made one last attempt to re-insert the battery, then the LED did not start to illuminate !
So for a verry short period of time i had good hopes that it was oke now... but then i plugged in the AC-adapter, the LED was amber again..
But the phone again will not turn on, and when i remove the battery and re-insert it it still shows the amber LED without the AC-adapter plugged in...
Right now i am at the point where i am not sure what to do anymore.
I was wondering if any of my fellow XDA visitors have experience with such an issue, or maybe even know a fix for this..
Some ideas to test or how to fix this are verry welcome ! :good:

I had a tp2 do something similar to this after it was hit with a power surge. Data would work, but no charging. Sadly the best suggestion at this point is to get a battery charger off ebay for like $5 and/or look for a replacement phone on Ebay/Craigslist. If the chip controlling the usb port is damaged it may work partially, and there is no way to repair it.

The chargers i got seem to be fine since i can charge my other TP2 with both of the chargers and cables.
I guess my only option is to leave it be.. cry... and move on with life...
Maybe, someone else has an other idea...

If you have a known good fully charged battery, and you can't make the phone work with it, then you sadly are probably out of luck.
That is a hardware failure, or a software failure requiring something along the lines of a jtag repair.
I was reading the text as though the phone would turn on with a charged battery, but wouldn't recharge the battery. I guess I misunderstood.

[Q] damaged usb port?

Hi all,
I wanted to give my z2 a quick charge on the way to the hospital today and i noticed after about 20 mins i noticed that the charging light wasn't on any more, it was to start with.
I ran it down to 0% it shut down and doesn't seem to charge via the usb port, the red light will come on for 5 mins or so but then nothing. when i tap the power button the screen shows me one bar on the battery but not charging icon.
I have a magnetic charger and so far do get the charging icon and a constant red led. It always takes a long time to charge via the magnetic port so I will leave it for a while but was wondering if this had happened to anyone else.
The phone wasn't moved or banged around in the car, it was fixed when it was charging otherwise I would say it was damaged.
The phone is 5 months old and has always been well taken care of.... really hoping i don't have a brick!
When it powers off it goes into emergancy power mode for a while
Leave it plugged in for about 40 mins, if it doesnt give any response at all then wait sometime ive read some peoples devices took a couple hours to wait
If it doesnt give any life then you will have to contact sony mobile repair centre
Thanks! I got it to 68% using the magnetic charger going to clean the USB port and give it another go
