Hello,
I've a Wizard that is approximately 20 months old. Yesterday, before I went to bed, I set the alarm clock on the Wizard, put it next to bed and went to sleep.
This morning upon waking up I tried to switch on the Wizard but it couldn't. Firstly, I thought the battery was discharged, so I tried charging through USB on my computer -- it wouldn't charge or start. Then, I tried charging on the default charger -- again nothing.
I tried removing battery and soft reset - nothing. It's really weird, yesterday I left it working, no-one has touched it and today it's totally non-responsive.
Any ideas what might be wrong/how can I bring it back to life? Would a hard-reset help?
Regards,
1. how much charge was in the battery last night?
2. is your battery 20 months old also?
3. do you have a spare battery to try?
4. do you have many applications, music etc. on the device?

Unfortunately I can't remember, however I have an alarm which sounds periodically when the battery is below 20%, so I'm guessing I had at least 20 percent. Could be wrong, of course, but most likely above 20%.
2. is your battery 20 months old also?

Yes, this is the original battery. Aprx. 20 months old.
3. do you have a spare battery to try?

I don't have that. I guess I could go to mobile phone service shack and check there. Do you think it's the battery?
4. do you have many applications, music etc. on the device?

The Wizard came with a 64MB card I think. I had around 10MB free space. 3-4 applications, 2-3 mp3s. Nothing unusual.
Same thing (sort of) happened to mine after about 187 months. I was using mine and it hung up. I hit the reset button and that was the end of that. Even when plugged in it does nothing. Tried a hard reset... nothing. Soft reset.... nothing. Dead. Zip. Nadda.
Good news? Replaced it with a Kaiser!

Mine died too when i was flashing...
Leave the phone in the original charger for a while and see if it picks up...sometimes it comes back to life by doing that...
If that doesnt work, try a new battery, you might be lucky...
A somewhat strange development occurred today:
Today (3 days after it stopping working) I randomly tried to switch the Wizard on and it indeed switched on. It showed that it had 0% battery. It didn't even show 0%, basically the battery charge graph was empty - no number, no fill, nothing.
While it was on charge the charge light was on (while it was 'broken' the charge light was off when I tried to charge). So I left it to charge and when I checked back in 15 minutes it was back to being 'dead'. Can't be started, no charge light, nada.
I don't really know what's going on, however I'm highly suspicious of the battery. Currently, I'm periodically trying to switch it on again so I can backup my data.
Any ideas what might be wrong with it, do you think it's the battery or is it more serious?
Regards,
The battery won't charge if it gets to low.
There is a thread about using a 9V battery to get the battery up to a level so it will charge. I don't have the link for it, try searching for it or maybe someone else will reply.
You might have a bad battery. I bought a new battery because I didn't think I was getting the life that I should. I tried using the old battery about a month after when I had to run out and my main was low. About 15 minuets later my phone started shutting of and rebooting. That was the end of that battery.
Yep, it's possible. If the battery is to empty, you can't charge the phone. It is stupid but it's just like that. You also can't power on the phone without a battery with the charger connected.
Yesterday I received my wizard and I had to revive my battery too because it was completely empty. I used a self made 5V power supply and after 2 minutes charging I placed the battery in the wizard and was able to charge and boot with the charger connected.
Here's the 9v battery trick, connect the + from the 9v battery to the + of the phones battery and the - to the -, hold there for only 10 seconds then remove the connection for 10 seconds and then repeat the process about 8 to 10 times and then put the battery back in the phone and connect it to the wall charger to fully charge.
Thanks for the advice. I'm going to do the jump-start thing.
However, I've hard time determining which is the - and which is the + pin layout on the battery, since the label is not correctly applied.
As far as I can see the - is the one at the far right, however I'm not sure which is the + pin.
Can someone help me with this, please?

When you take out the battery and put it back in that direction ,turn and face up the connector side fasing you,the first connector from the rightside of the battery is the ' + ' and the last is ' - ' towards the leftside.Be careful while connecting and try not to touch other connectors. Don't keep the connections longer then 10 seconds interval.
good luck
Xeno1,
My MDA battery also died and went below re-chargeable state. Your trick to use 9volt battery to jump-start it worked just fine for me. I connnected for about 20 seconds (2x times) and plugged it back into phone and connected USB cable to it and my nice yellow charging light came back on. After about 30 mins, I could use the phone.
THANKS FOR THE GREAT TIP!!!
easier fix, take a standard usb cable. rip off the smaller end with a wire cutter, expose the red and black wire. take out your battery, than connect the negative(black) wire to the negative end of the battery, than the red wire to the positive end of the battery, leave it in there for exactly 3-5 minutes for jump start. after that turn your wizard on, and quickly shove it inside a new usb cable. or the wall charger.
note:
if not done correctly, you may damage your wizard or the battery. if theres a power overload or your power goes out. your wizard will burn out!
feedback is greatly appreciated.
p.s after that my battery seem to be weak, charge barely holds for 12 hours. after 12-14 hours it will die out. so i suggest buying a new battery after couple of days.
Thanks guys! Vario died yesterday and wouldn't turn on or charge.
Tried the 9v battery recommended here and it worked! I was a little unsure which end was - and which was + but using the advise above, got it right. Wasn't too worried as found and ordered a replacement from ebay this morning for £7.
The first connector on the right hand side, nearest the end of the battery is the + the one more towards the middle and further away from its corresponding end is -, or at least, thats what worked for me.
Thanks again!
Experiencing the same issues after I set aside my Mini S as it was experiencing problems with regards to its screen alignment. Wasn't able to charge it during that time I kept in the drawer unused - due to frustration as I can't use it anymore. After downloading a guide to disassmble it so I could remedy the problem I found out that it won't power up anymore even with a new battery.
Well, haven't tried the jumpstart thing and the original battery was disposed of already to try the jumpstart idea. Could it be the internal battery is causing the problems? I opened my unit up and tested the internal battery for power and it registers a measly .2V left. Will use the 9V thing to power it up (as been doing that before on watch batteries that are hard to find replacements) before I do it on the main battery. Here's hoping it works as the Mini S has been quite useful for me until now.
UPDATE: I charged the internal battery and it now reads 1+ V and the external battery at 3+ V. No luck yet though as the unit still won't show any life. Any suggestions?
Vivanov, I know it's been a few years now, but did you end up fixing your problem? If so, how?
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.
So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?
Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.
So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.
So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?
I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?
Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.
I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.
So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.
Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.
well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me
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.

Sounds like something my phone did a few months ago. I was able to resolve the issue by following the steps in the post below.
http://forum.xda-developers.com/showpost.php?p=11699369&postcount=10
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 demondo, im having the same exact problem as you and im also with mango, can you please explain a little better what you did ? Until now nothing had sucess for me
Thanks
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.

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*
So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.
