8125 Dead

I have a 8125 and I was able to unlock it fine. After unlocking it I upgraded to the underground crossbow edition rom - which the 8125 rebooted and was running. I tried out a couple things and everything seemed to be running/working fine. It was getting late so I put it down and went to bed. This morning when I got up the phone was off so I went to turn it on and nothing happened. I figured it just ran out of battery power plugged in the charger and guess what no red light on. I have tried everything under the sun but I cant get it to charge or startup. Anyone have any ideas? It was working fine.

i know u said u've tried everything and i don't mean to sound like i'm takin the buscuit, but leave it on charge for n hour, then try bootloader. taking the battery out completely for a while could work.
i had so many problems with crossbow! think this was one of them.

Unplugged
Well so far I left the charger plugged into the phone with the battery in it for over an hour now - with no luck. The red charging light doesn't even come on. Did you have that problem? I also left the battery out and plugged in - still nothing. Tried taking the battery out and then putting it back in while plugged in - no go.
I have not tried the "bootloader" - but the phone will not turn on at all or respond in anyway. Its in a powered down state (or so it seems) - I dont think bootloader will work?? But I dont know anything about bootloader - is it on the ftp site and how do I use it?

Any chance the battery could have been completely discharged?..just a thought. I think i read that completely flat batteries wont charge up via usb. Disregard if thats a silly suggestion, just thought id offer my two cents.

try getting a new battery and see if it boots up...it can be your battery.and you are trying to charge with an AC adapter right?

Wall Charger
I am charing it via the wall charger (not usb) and I am going to try to get another battery. Just weird that I never had a battery problem until I install the wm6??!! Unless the damn thing drained my battery dry and somehow damaged the battery. I called Cingular and they are sending me another unit as its still in warranty. So we'll see when I get it - I will try the new battery. Strange. Very Strange - because everything was working last night.

Strange
Well after leaving the battery out all afternoon I took a go at the phone again, put in the battery then turned it on. It actually started booting up - showing the WM6 bootscreen. After about a minute it shut down like it was out of power. Strange. I know the phone is not bricked because if it was it wouldn't have just done what it did. Anyone have any suggestions how to fix it?

Could be a bad battery. You need to test out with some one else battery

u shud have plugged it in while it was booting...did u?

New Battery
Well I finally got the new battery I ordered today. When I put it into my phone it will boot into wm6 fine but will not sync with activesync 4.0 or charge via USB or plugged into the wall. I uninstalled activesync, rebooted my computer and installed Activesync 4.5 - but still no luck with the phone via usb syncing with my pc. Also when the phone in plugged into the wall via the wall charger it does not charge. I am beginning to think the port on the bottom somehow was disabled from the rom update, although I dont see any posts with people having that problem. I guess my next option is trying to reflash it to stock rom via a sd card since it wont connect via USB - however I can not find the information step by step how to do this. Can someone point me in the right direction?

Try going to the bootloader screen: Turn off your phone and then hold the camera button while you turn it on. When you are at the Rainbow screen (thats the bootloader) plug in your USB cord. You should see in the bottom left (above the left soft key) where it says USB. If it doesn't then I'd say your USB port is broken (I'm not aware of any ROM being able to disable that).
As for flashing from the SD card, I believe thats documented in the Wiki...

Athena dead or dying........any miracle workers out there?

Background:
I have had MANY PPC's (so many I can't even count them) and I've loaded many different cooked ROMS and such on most of them so I'm not a complete noob on these things (don't claim to be an expert either).
However, my most recent acquisition is an HTC Advantage bought at CompUSA. I've read most of these came with a test ROM and mine was no different except for the fact that when I attempted to update the ROM to the "official" one provided to me by HTC it would not work. I always got the error "Connection lost" about half way through the process. I tried it numerous times and it never worked. On some occasions it would get stuck on the bootloader screen but I was able to get it back to working status (still on the test ROM).
I decided to try installing step 1 of Ollipro's SPL to see if that would help loading the HTC ROM. Turns out that wouldn't work either. It would get stuck at step 1 where it would ask if "PPC gone idle and didn't work or to wait 30 seconds". Tried it many times and would try to get it to keep going but the grey box on the bottom left would say the "parameters were incorrect" and would give me the option to quit, which I would. No problem, at least my 7501 was still working.
After that I tried the official HTC ROM again and I got the same "connection lost" error I had previously, except this time I didn't get anything on my PPC screen, just a black screen, not even the battery charging light behind the joystick lights up anymore. Soft reset...........nothing. Bootloader reset....................nothing. Hard reset.......................nothing. No lights, nada. The only flicker I get is if I try a reset wheen the power cord is connected. A red light flickers behind the joystick whenever I click the reset button. Any ideas or any help?

Sounds to me like the battery is just dead. I bought one at CompUSA (had the test ROM also) and I got the red ring around the joystick too when I tried to turn it on in the store. I left it plugged in awhile and it finally booted up okay. I then replaced the test ROM with the one and only available for the X7501 on HTC USA's web site. Good luck and I hope you get it working!

I think it could be battery related as well but it had a full charge when this happened. For some reason the unit has lost communication with the battery. I'm at a loss.

I got the same problem like you man !!! but i bad luck and so stupid man , i did with HTC X7501 then it dead after that i bought the X7500 then did it again , holy "... " it dead again....man ...So how your phone now bro ????

I left out the battery a half day and tried it again but still dead. Then I left it charging overnight and tried it again but still dead.
I can't believe this. I've never had a bricked device that can't be revived but after so many have seen this post and still no solutions I'm guessing it's no hope.

I met the same situation when I started to unlock Athena ( TMobile Ameo) within not fully charged battery ( less then 70%).
Solution ( try to make BL mode) with connected wallsocket charger ( not connected to PC USB slot) or find 100% charged battery. It helped me two times.
After many tries it changed to BL mode .
Now I didn't start unlock/change ROM without 100% charged battery.

I have the same BIG Problem, only red fliker when soft reset when AC conected. I wanted to update rom from russian to english and phone stoped working (black screen), and battery heats when inserted in phone . nothing to do? i read everything but i have not got any solution. I think it may be bios dead. helap us please

"heating battery" (i.e. discharging when inserted, you mean?), no charge led = dead bootloader indeed.

I get the same problem. My device is work, but not charge. Also like yours i have red ring around the joystick when the battery is taked out. And if battery inside, when i make a softreset it blink one time, continued to load but not charge.
You`r speaking all wonderful. But have anybody found the solution?

Hearing these stories makes me nervous. I'm on the stock ROM (mine came from CompUSA with the latest ROM and I don't have an urge to try the cooked ROM yet). I've been using my Athena daily for 4 months, it charges correctly from several different chargers I have (car, computer USB, stock wall charger, aftermarket wall charger).
However, one day 2 weeks ago I went to make a call in the middle of the day and my Athena was dead. D-e-a-d. Usually I can make it back home at night and still have 90-100% on the battery meter, so with no use in the middle of the day and a dead battery, this was weird. It wouldn't turn on, no soft boot, took the battery out and put it back in, and always got nothing.
I bring this up here because when I plugged it in, I encountered similar problems that others here are describing. It wouldn't turn on, and it didn't give me the orange charging light behind the joystick. I ended up leaving it plugged in for a while and finally I got a red ring, not the usual orange. I've only seen red when the battery was almost dead and the unit was on. Then after some more time the ring turned orange and at this point it would turn on again. I still have no idea why my battery died so fast and hard.
So, is there a problem with the battery charging system that is starting to crop up in units that have been used a while???

Hi i am no expert but i had simaler problem no display or no lights round ring no responce to any commands (ie hard reset and bootloader ) only red light flickred on reset button all i did was removed battery while pressing reset button and placed new battery and left it on wall charger for couple of hours and before doing hard reset i pressed reset button 2 to 3 times and green light round the battery came up so i tryed bootloader and it worked and insted of flashing it with pc i just loaded the img in sd card and flashed it while whole thing was on charge (i had tmob test rom before ) which i think is best way to do no hassle of losing connection or failing in half way and it works like a charm
hope this helps
and ya if you have a spare battery it dose help

New battery?
I'm a wizard user (and lots of former PDAs) looking to buy and Athena, maybe.
Has anyone tried a new, right out of the envelope, battery? these issues sound like worn out Li-Ion batteries to me. I've had them completely conk (won't take a charge at all) if I let them go completely down, and I've had them wear out and stop taking a full charge (down to maxing out at about %20, but sometimes showing %100 depending on ROM status) when I kept charging them while they're already charged.
Li-Ion batts don't sit for long periods too well, either, so if they're sitting on the shelf at the store/warehouse, they may be suffering even more than one that has been used since earlier in its childhood.
Perhaps the answer is a switched charger that stops charging when the battery (not the ROM/unit reading) gets to %100. ???
I didn't see anything like this posted. I'm terribly curious to see if anyone can resolve it.

WIZ don`t power up

I though my battery died so I bought new one, but it doesn`t respond also.
On friday there was problem with display and device automaticaly restarted
I opened it and something like this is not connected anywhere. I can`t see anything in service manual like that. Do you know what is it and where it suppose to be connected ?

That's a holder for the stylus.
There's a small screw that goes through it when it's in place and it holds the stylus from falling. It's very easy to place it back!

Ok, thanks, so it`s not for battery so my wizard is dead definitely

It may not be your battery!
I had my wizard die in much the same manner as your's. I thought it was a gonner until I ran across a site somewhere with a whole group of people with the same problem with their wizard. I'm only guessing, but I think you let your battery run very low and the device shut down, which is alright, until you consider that it cannot charge without the operating system (Windows)
up and running! I had to cut the mini end of a usb to mini usb cable, strip the black and red wires and hold the black to the negative pole of the battery and the red to the positive pole while it was plugged into the usb port on the desktop computer for about 20-30 seconds. Then replaced the battery in the phone, booted windows and recharged with the home charger. It worked great, but now I carry a fully charged battery with me, in case it happens again and I,m out somewhere where I can't jump start the battery with the cable trick. I think this method is also mentioned somwhere on this site. Good luck and let me know if it works.......

Oh. I also though it is the problem with charging, but the night before my battery was fully loaded and in the morning the phone died without possibility to boot up. two days later I`ve buy the new battery and put into the Wiz...nothing.
I asked salesmen if it`s possible that the new battery is charged under possibility of the phone, but he said it`s definitely not. So I suspect that something happened to the hardware.
I`ve tried connecting USB directly to the battery also, before I buing new one, but it also didn`t worked for me.
Before it completely died there was several hangups on today screen and once even on the booting splash screen, with the strange situation where the radio ROM was not displayed at all :/ ??
After this several reboot sesions it has not started again.

I didn't catch the whole story from the beginning, but did you drop the Wiz? I dropped mine, and I am going through the same exact thing with the Radio not showing up. Mine only gets to the first splash screen, and enters an endless reboot loop.
If we can find a solution to this problem, I'd DEFINITELY love it. Until then, I'll still be sad.

Hi there,
As you can see I'm very new to this forum but I too have just come across this problem this morning.
My battery was fully charged yesterday and I had my alarm set to wake me up this morning but it did not go off. I checked and it was all set ok so I did a soft reboot. It hasn't come on since. A took out the battery for a while and it managed to boot up to the WM6 screen but then switched off.
Now it seems the device doesnt even switch on
IPL/SPL 2.22.002 (I think from memory)
OS 6.0xxx
Running the TNT rom not sure what version (was ebayed)

Have you plugged it in through the wall, and not the PC? Somehow mine came back to life this morning, all I did was plug it into the wall AC power WITHOUT a SIM card, and it booted like normal first try.

Really annoying problem...

Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.

I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.

Sounds like a defective battery to me...

That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...

Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.

Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.

Dell venue pro not turning on?

Hey guys, just wanted to see if anyone else was having this problem, or if possibly my girlfriend has a defective unit. Like i said, my gf has a dvp but when it dies and i connect it to a charger (1 amp) it'll sit for 10-15 minutes and still wont turn on. I was able today to take the battery out, let it sit for a minute, then put it back in and turn it on, and it did just that. And then it showed that the phone was charging. then after a few minutes it turned off.
Anyone else have this problem? Because i know as is, the phone is supposed to turn on automatically because the phone has to be on to charge (a wp7 "feature")
anyone think i have a defective unit? By the way...today when it happened it was the 2nd time its happened to her so far.

It's happened a couple times on mine since I got it in late December.

I am currently having this same problem. This is distinctly different from the other crashes (Marketplace/wifi kindof thing), which is often resolved by quickly removing and replacing the battery, which many are waiting for the April 18 Dell firmware fix to resolve. (Better to hold the power button down for 5 secs than constantly remove the back and battery.)
This is different. The phone is quite dead. The power button is completely unresponsive. The battery must be left out for at least a minute. The phone doesn't even charge when in this state, as I left it on the charger overnight. It does recur as well, but I haven't had time to fully investigate. I have had the nodo update for a week prior to this occuring, so that may not be related.

Having the same problem, and as the guy above stated, THIS IS COMPLETELY DIFFERENT FROM THE NORMAL CRASHES. This has started for me since the NoDo update. Pulling the battery does nothing. I just have to leave it sit and come back. Sometimes it restarts on it's own after 5 minutes and sometimes 2 hours. Either way, I am sick of this lemon.

Same here
Hey i am having the same problem also. I thought it was just because my phone completely died. It turned on eventually and then i had it charging overnight and now its doing the same thing. Seriously thinking about going back to android. So many problems.

I'm having a very similar problem to the one described above. Earlier this evening I unboxed a completely new Dell Venue Pro. It was carrier locked to T-Mobile, but I have subsequently unlocked it with the code provided to me from Dell directly. My plan is to use the phone on the Rogers network in Canada, and right now there is no SIM card in it.
Anyway, the phone refuses to charge properly. When it has the battery in it, and I try plugging it into the wall, the phone shows a full screen icon of a battery with a AC plug on it (I assume this means the phone is fully charged.) However the moment I unplug it the screen goes dark and there is no way of turning it back on. I've tried holding the power button, I've tried pulling the battery, putting it back in, and then holding the power button. Nothing seems to work.
If I plug in the phone into the wall with no battery in it. I can get into the OS. If I then put the battery back into the phone while it is still charging, it'll show that the battery has no charge. After a few minutes (in the ball park of 5-10) it'll again show the full screen icon of a battery with a AC plug on it.
I've compared this to my friend's Samsung Focus which was plugged in when it has no charge. The Samsung focus will show a full screen critically low battery icon when first plugged in, then as it charges we'll get a full screen low battery icon, and then the Windows Phone 7 OS itself will load. (It is still not fully charged, so I do not know if we ultimately get the full screen icon of the battery with plug.)
Both phones (Samsung Focus and Dell Venue Pro) have been charging for over 2 hours now. The Samsung Focus is in the WP7 OS and shows an increasingly charged battery. The Dell Venue Pro still has that full screen battery+plug icon.
The only way I can access the WP7 OS on the Dell Venue Pro is to take out the battery and plug it directly into a wall, or directly into the computer. I have succeeding at carrier unlocking it and upgrading the OS all the way to Mango using this approach. However the phone just refuses to run on battery power.
Has anyone else run into this problem? Do you think it is the phone, or the battery itself? Any advice would be appreciated.
P.S. Sorry to bump such an old thread, but I'm a n00b, and the video said to find a thread related to my problem, and post there.
Edit: So the Samsung Focus finished charging. It lets me interact with the WP7 OS, and does not have the full screen battery with AC plug icon. Although it does have a much smaller version of the icon on the top of the screen where the remaining battery icon is.

The issue hasn't happened since. Not sure if it's the same issue but give it a try and see if it helps

THANKS, it worked!
I know I tried those steps (from the same post) before upgrading to Mango and it didn't seem to work. After upgrading to Mango, it did work. The only variation I made to the steps was that when you try to shut down the phone (while holding the power button) I also swiped downward, as that is now needed with Mango.

Hi Mauriciovsky,
I do not know what the minimum number of steps is to get rid of the problem. Here's what I did, but probably some of it isn't needed:
Charge the phone (with battery in it) using the AC adapter for a few hours with the bettery + plug icon. (I charged it until a Samsung Focus was fully charged.)
Unplug the charger.
Take out the battery.
Plug in phone to computer over USB.
Update the phone all the way to Mango. (You know you're in Mango when holding the back button brings you to the tile view of your running applications.)
With phone still plugged in to USB, plug in the battery.
(MAYBE) unplug the phone from USB. I can't recall if I did this step or now, I don't think so, but maybe.
Either way, turn off the phone. This is done by holding the power button for two seconds and then swiping downward when instructed to do so.
Unplug the phone if you haven't done so earlier.
Hold the power button for two seconds, then let go. The Dell logo should appear, and the phone should boot.
Sorry I can't give you a more concise explanation. However, the phone has been working great in the few hours since the problem went away. Hopefully it'll work for you too.

Thanks a lot for the help demondo and the other guys

I had the same problem: my DVP's, running WP7.5 "Mango", battery got drained and when I tried to turn it back on it would not boot, not even when I hooked it to a power outlet. I finally got it running again, here's what I did:
1. Take out the battery.
2. Turn it on (you should see the Dell logo by now).
3. Put the battery back. (It will alert you that the battery is critically low).
4. Charge it.
*Hope this helps*
