Today, I found that I can no longer turn on my Jasjar. The power button does nothing and I can't enter bootloader mode. I've also tried soft resetting but there's no response. There's no lights whatsoever and the screen remains blank.
When I plug in the charger, there is a solid red light but no further response when power button is pressed. I checked the battery with a multimeter and found it has about 3.84 volts.
Prior to this, the device will turn off randomly at various power level without warning. The battery is about 14 months old.
Is this a battery problem or a hardware issue?
Welcome to the forums
It could be any of the options you mention
If you can try with another battery
Have a read on the wiki, there is a section about batteries
Good luck,
I'm having the exact same problem. Solid red light. Happened after I tried fixing the headset pin. I had the battery taped so I could test if there was sound coming out without having to hold it down. I was doing something when I accidentally moved the battery and the problem started. Solid red light, no battery detection, no computer detection, battery reads same 3.84 volts. Any ideas? Shorted mobo?
Sorry to hear that. I bought a new battery but it didn't fix the problem. Maybe you'll have better luck.

Does anyone know if the Wizard is capable of charging its battery in a completely powered down state?
The battery on my Wizard (G4 Qtek 9100) was low today, but I just ignored it, the battery ended up running down completely to the point that the phone powered off, and would not turn back on when I tried to repower it. I connected the charger and left it sit for about half an hour, the charging light did not light, but I left it to charge. After the half hour I figured it should have gained enough charge to power on, so I tried and no luck. Luckily I have a charged spare battery, so I left the dead battery in the phone and wedged thin wires in between the dead battery contacts, and the phone's spring loaded contacts. I connected the + of the dead battery to the + of the spare, and the - of the dead to the - of the spare. Now both batteries are connected to the phone in parallel. This allowed me to power the phone up and boot it all the way up, where the charging indicator LED lit. I disconnected the spare battery, so that the dead battery can charge on its own. Sofar it looks like it is taking the charge.
I'm wondering if some of the people that have "bricked" phones might have run into the same problem that I have. If you have a "bricked" phone, try using another battery that you know has a charge.
go in registry with totalcommander or something similar to this key:
HKLM\Drivers\BuiltIn\usbfndrv
and change : EnableUsbCharging to '1'
press reset after u done this.
i had this several times with death battery and wouldnt charge on usb on the
computer but it did with the original charger.
Thanks, i'll give that a try. Just curious, do you know anything about how that works? I'm wondering how a registry key can controll a piece of hardware that has been completely powered down, and that windows mobile hasn't yet booted on.
Wing died.
Soft reset didn't work.
Hard reset doesn't work (soft keys and reset).
Battery voltage with no load is 4.02V without charger on (no LED's on phone work). Battery voltage measured while in phone is same. With charger plugged in, battery voltage is 4.14V but no charging LED indicated on phone.
Boot loader doesn't work. There are at least 3 different methods posted on how to accomplish this:
1. Camera and power button
2. Camera, Voice and power button
3. Camera and reset
Tried all combinations. Nada.
Phone when it went through its death throes, powered up to the Tmobile screen, started vibrating, then shut off. Once it made it far enough to display a low battery warning (battery was legitimately low), then died.
Stock software, nothing flashed or diddled in phone.
Any suggestions?
A different battery may be helpful, hehe no time like the present to grab an extended battery; know what i mean?
Some more troubleshooting:
Put battery from broken Wing into working wing. Battery won't power good Wing, so battery is AFU.
Put battery from good Wing into broken Wing. Broken Wing still broken.
Bad Wing. Not encouraging.
Hi there,
Yesterday I decided to dive into ART just to see what the differences may be. I ran into some trouble. I got it fixed but thought I would share my experience in case it may help someone else.
What I'm running:
Nexus 4 (mako) with Faster binned chip
Purity Rom 11/27
Franco Kernel 195
SuperSU 1.65
CWM Recovery
When I decided to switch to ART I had about 70% battery remaining. I did the switch and the phone rebooted to change over the lib. The phone booted as it would normally and was optimizing applications. I noticed that the phone had got really hot when I picked it up to check it. The screen was off at that point and I could not get it to turn on.
I connected it to a USB charger and I got a flashing red light. Crap. I followed the guides out there which advised holding Vol Up and Power for 60 seconds, releasing, and connecting power. I let it charge for over an hour as prescribed. This did not resolve my issue. I tried a few different chargers of varying output and found that the lower powered chargers gave me a blinking red light (trouble indicator, I believe) and my new iPad charger would give a solid red light (charging from a very low battery indicator). It still made no difference in booting however.
If I held down the Vol Up and Power and connected a lower powered USB charger I could get to fast boot which led me to believe that the system board was not fried. When I disconnected the power while in fastboot the phone would switch off. Seems that somehow a fuse (electronic I'd guess, I'm not an electrical engineer) was keeping the battery from powering the system board.
To resolve the issue I had to open the phone, disconnect the battery ribbon, wait 10 seconds and then reconnect it. Fired right up after that.
To open the phone you'll need a t-5 torx screwdriver, a non-marring pry tool and a small phillips head screwdriver.
Hi,
Thank you for your solution. I have the same problem and I couldn't fix it through flashing a factory image. I am confused though. Do you know why the problem is fixed by reconnecting the battery cable? I'll try whenever I get the tools to open the phone and I'll post back if it worked or not!
tommyboy76, got same problem, but fixed it by waiting about 2 hrs with "dead" phone, I didn't connected charger until it chilled down. Then after I connected charger and everything seems OK. It charged and turned it on as always.
I think it is an overload protection built in.

Recently my n4 has been giving me a flashing red light whenever i turn it on. No matter what combination of buttons i press, it doesn't do anything. Please help! Using a 1 amp charger.

There have been many cases like these. I think you will get enough hits if you use the search button. I had it myself recently, though the solution seems not to be very solid.
The best way to get it to work is to try different cables/chargers (via PC/Wall Chargers etc) and let it charge for a half hour, and try to start it. If it doesn't start, try another combination. Rinse, repeat.
A stronger charger seems to work better most of the time (2A for example).
In the end I got it to work with the 2A charger of a colleague that he always carries with him. I am assuming that there is nothing wrong with your battery besides it being completely drained.
Im not really sure though. Is that what the flashing red light means?
Open the phone up, pop off the battery connection, put it back, then try to reboot (you can reboot with the cover off). I got the red light after my N4 crashed doing an Antutu test after OC'ing it to 1.9GHz (yeah...don't do that), and after "resetting" the battery, it booted up just fine.
I had ever occur this issue and tried any fix from internet, finally completely battery died, so just buy a new one of battery .
Your battery is discharged to a critical level (1-2%) and the phone performed a shutdown to save itself.
Connect your phone to the charger and press POWER + VOLUME DOWN, to enter recovery. Then reboot from recovery
I had the RED LIGHT flashing and this is how i fixed my problem. No need to buy a new battery
Ur phone can't boot up cuz there is not enough energy from ur battery, so just charge ur phone for a while then u can boot up ur phone again red light issue usually for low battery and the phone can't booting up
i doubt it if mine is power issue. I've charged for long periods several times, i've tried several things i could find on the internet, i used a working battery, still no show. light blinks for a while and goes off when plugged to electricity. I'm thinking this could be a different problem entirely
Hi Guys, so I flashed Resurrection Remix and it was working fine. Few days later, I woke up to my phone continuously vibrating. Upon checking I saw that it was vibrating because it was doing a boot loop. Unfortunately my PC was broken at the time too, tough week.
Anyway, I let it do it's thing until it runs out of power. It never did. Seriously I waited for a day. When I slept, it had 20% battery (not charging). So I thought maybe, the power button is acting up again which has happened many many times before.
So I opened up my phone and adjusted the power button. Even, holding the volume up while plugging in didnt work anymore.
While I was there I saw the battery connector thingy, I unplugged it and re plugged it real quick without breaking anything. And It restarted and the device worked fine.
But.... The battery icon is steadily at 50% for a min then drops to 0% even while connected to charger. So, I charged it for a few minutes but it doesn't move.
I was about to do a factory reset but it shut down. The battery icon doesn't appear, only the red blinking led light. I tried charging it like that overnight to no avail.
I then tried to remove the battery connector again and as soon as I plug it, the screen turns on then off again. Sometimes it gets to the battery charging icon before it shuts down. If I bend the connector downwards it sometimes turns the screen on and sometimes doesnt.
I took it to repair shops and they said that the problem is the battery and ofc to no suprise, they dont have a replacement.
Do you guys have any idea what happened? Was it a button issue, software issue or indeed battery issue. Before all this happened, the device was working perfectly.
Please help. I miss my phone already.
I think it due socket of battery, can you open the back cover and plugout and plugin this socket, will be OK
