Is there any possible way I can power on my Universal without a battery? Please help I need to do this very badly. Thanks for the help.
If you are near pc, you can just take battery off and plug it in pc using usb.
Works for my Kaiser : )
With battery removed Universal will not stay on even for a second. Without battery only orange light turns on but the device remains shutdown if the cable is connected.
On my Prophet at least, if you plug it in, with the battery, and then start up the device, you can remove the battery and have it running off the Mains...
Universal cannot be tricked that way. It turns off, orange light on, when battery removed after connecting cable. Waiting...........

Hi,
Was trying to reflash my Jammin and after it completed and reset, it wouldn't boot with the USB cable plugged in. The screen flashes white, and both LEDs flash simultaneously (red for the top LED, and blue for the bottom), and this is repeated in a boot loop.
A similar thing happens when I unplug the USB cable and press the power button, except that it only happens once then turns off.
However, if I plug my mains power charger in I can get into the boot loader (so it's not bricked) and can in fact boot into the new ROM (Button ROM). Interestingly, in settings the battery indicator says there is 0% battery.
Now I don't think this is a battery problem. I have tried a friends fresh battery and the same things happens. By going into boot loader and switching off with the power button I have also got the original battery to fully charge (until yellow LED turns green).
Here is the thing that has me really frustrated. I can boot into windows (using the mains power cord) and during the boot can change to the USB cord (no reset and boot cycle). So Windows works with the USB in and Activesync detects the phone. However, when I try to reflash to another ROM the update software throws the following error: Error [220] mains battery power, because it reads the battery is less than 50%!!
Please help me!! Any ideas are appreciated.
Gavin.
I'm thinking that I may be able to solve this with the "cutting the mains charger wire trick." This will hopefully provide the necessary power while flashing, and allow me to have a USB/activesync connection at the same time.
Any thoughts before I destroy a perfectly good charger?
well seems I've solved it with a bit of surgery. used this method: http://forum.xda-developers.com/showthread.php?t=319636 and it boots into my new ROM!! Yay!
So, I accidentally let my phone run down to zero battery. Now it won't turn on, even when plugged in. It used to show the empty battery icon, but now shows nothing, not even that icon, or even the LED.
Anyone have any ideas, or places to point me out to.
I'm gonna leave it charging overnight.
So, leaving it charging overnight seemed to do the trick.

So, i did it from this link
-------------------------------------------------
Use the electrical outlet charger (not usb pc or notebook), connect the device and hold the power button until start. (may take up to 2 minutes)
After the LED next to the front camera light up, release the Power button immediately.
The LED lights up for some time (in my case, more than 30 seconds) and may blink, then turns off and the phone will light up the loading screen with the battery indicator at 0% (zero percent), and turns off again.
Pressing the power button again, just once, without keeping it pressed, the phone will not turn on, will remain off (not rule because he can light with the target load, it depends on the charge status of the battery). But do not worry, leave loading for a few minutes without stopping and soon the phone will light up indicating more or less a 5% (five percent) of battery charging.
Now most importantly, do not connect or disconnect the phone from the charger until you complete 100% (one hundred percent) of the battery charge. This undoubtedly is the crucial and most important point of this walkthrough. I repeat: do not remove the charger or plug in your cell before reaching 100% (one hundred percent).

it happened with me too...
Just put ur phn in recovery mode...by pressing up vol+power button and then dont use wall charger...at this time it wont get charge from there.

So today I was using my phone and then i could turn the screen back on. So i pulled out the battery and tried to turn it back on, however it didnt work. I tried plugging in the charger, but there wasn't any orange charging light (it was on around 60-50% battery when it stopped working). I tried connecting it to a pc, but there was nothing, i couldnt access the sd card and there was nothing on the device manager. I tried doing the volume down and power button and other stuff, after a while i managed to get the phone to boot up but it died before it made it to the lock screen (not charging). Is there away to fix it?

Try removing your battery and then plug in the cable connected to PC USB. I would also try doing the same with a unix based system, just to be sure that there are no driver issues(though windows should at least show an unrecognised device in device manager).
Also, can you keep it on charge for some time and see if the phone feels a bit hot...? If not, it seems to be hardware fault.

Maybe your phone is bricked,but the way you explained it seems like a hardware problem !
Do you have warranty ?
I CAN NOT charge my smartphone Charge only off or
Bootloader is the way it recognizes correctly when connecting and disconnecting the usb cable
Android System Started
On with the USB Cable: Indicates the battery icon as charging but in the state of the phone "indicates you are not ****ting", so disconnect and disconnect the cable does not recognize
On without the USB Cable: Does not recognize anything, neither connect nor disconnect
Loading with the Off: load very slow; By moment turns on and off the screen and shows the logo and then the percentage of battery
same problem but solved finally
Switch off your phone/ let the battery drained to null(recommended)
Try to start your phone at 0% to drain battery.
Screen will show 0% or plug icon.
Then connect charger then , then switch on plug of charger.
After few minutes screen will show battery at 3%.
Let it charged without disturbing, it may take more time.
In my case it take 1-2 days to fully charged.
After fully charged, notification light will show on speaker, then disconnect charger and turn your phone on.
Hope this will solve your problem.
If not repeat same procedure.
***Never turn your phone on/restart while charging it may create the same problem***
If the problem not solved, uninstall or disable "charging related noise problem" system app.
Problem solved
After trying to solve the problem by placing different ROMs and until flashing the Firmware the solution was the following
As the only way to properly load the phone was by bootloader mode; Leave charging the phone that way about 5 hours lego ignited the equipment even charging and that way began normal operation the equipment
Hey guys!
After two years, the battery of my HTC U11 drained so quickly that I had to charge it twice a day. I decided to replace it, ordered an original one and followed this guide: https://youtu.be/FY8ITVIkydM.
Now I have the following issue:
- Without the charging cable plugged in, it only shows the very first boot screen, after that, the phone shuts down
- With the cable plugged in, the phone boots normaly
- When the SIM-Card is inserted, it boots up, but after typing in the SIM-Pin, the phone shuts down
- Without the SIM inserted, I can start and use my phone (of course, without the cellular functions)
The strange things are: The battery value is wrong. When i plug in the cable after a reboot, it shows 58% and beginns to charge. If I charge until 80% and pull out the cable, the phone shuts down. After a reboot, Android shows 58% again.
Does anyone have an idea what the issue could be? I've checked the pin of the battery, it should be connected correctly. Does the system not recoginze the new battery and need a factroy reset?
Thank you in advance - cheers!
What happens if you use the old battery again?
