[Q] USB death after Root and Flash on Xperia ARC

HI all,
I flashed my Arc last night, and then rooted it.
All seemed to be fine, until I rebooted after the Root had been completed.
Once the phone turned back on, the battery had dropped from 70% to 1%. It was warning me that it was about to shut off, so I tried to plug it into the computer, via USB cable to charge, and nothing!! I thought it must just be my computer, so I tried to plug it into the wall socket, and still nothing! It just refused to charge. Full stop. However, it continued to tell me that I was bout to run out of charge and didn't turn itself off!!! I unplugged it 1000 times, and still tried each option ( computer/wall socket) and it just wouldnt work.
So, basically, this is a well known problem and you can solve this by following this procedure -
" try removing the battery for a few seconds then reinsert the battery whilst the wall charger is plugged in. give it 5 mins before attempting to switch it back on.
if it manages to switch back on, try to put the phone in flight mode until the red light turns a pale green. "
I did this, and turned it back on. Straight away the phone rocketed back up too 77% battery.
And, the usb port worked again.
So my question is this,
Is this a common issue?
And is following the above process ok for the phone? I hope that I wont have to send it back, cause the other people on that link above had too.
Is anyone else had this problem?
Thanks all for your input

This is a common issue, no worries Amanda! Same for me when I flashed the UK Generic 2.3.2 to obtain Root..

How did you fix it???

This happened to me also last time after a reflash. You may try to do a complete drain then do a complete full charge (don't turn on the fone while charging at this time).

It is for motorola, will it gonna work on htc ? Also when I charge my battery for 4 hours or for 48 ( turned off the phone I mean) it still lightning red led not green. Always it charged till 71 %

Worked for me on my WF using CM 7!

Okay I will try this, nut what about app Battery Calibration, does it work ?

Don't use an app because it is software based, but the guide i've posted is hardware based!

Ok thanks for the information !

1. While in Android, charge up to 100% and leave the phone plugged in.
it dosen't charge up to 100% to use this method

In this case 100% are the maximum you can reach. You can check the exact battery status in system settings!

1. Sorry, haven't thought about that. Yes, it has to be rooted.
2. If your phone is rooted you can find it with root explorer.
3. Yes, for rooting your phone needs to be S-OFF
Maybe you can use that one - found it in another topic:
1. Power on your phone then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Needs no root, but I haven't tried that yet. Most of the users said that it worked, but keep in mind that battery calibration can always damage your battery.

My battery never charge up to 100% last time i saw green light from fulfully charged phone was last year. I can charge it for 48 hours turned of it still wont be green

Which status is shown in phone->status->battery status?

A little help is needed, Flashing red light and won't turn on

Hello,
Yesterday i put my Desire HD on charging via the computer and everything was good, I woke up and found out that my phone is dead and the led indicator keeps blinking red light, put the battery in and out a few times, try to charged it a bit but same result, i can't turn it on or do anything.
Suggestions?
Thank you very much!

hi there are you using stock battery, if you are you might have a dead battery broblem, try to change battery but before you do that take the battery out leave it for 10 min then insert battery back into phone power + vol down enter booloader navigate to recovery and wipe battery stats then reboot

Thank you, it seems like taking the battery out for a few minutes did solve the problem, thank you very very much!
I haven't wiped the battery stats but at least now it's on so I can do it later.
Thanks again!

No problem friend, there is no risk in wiping battery stats, that might be the cause if it is corupted

[Q] Battery issue on LT15i, shows 85% and isn't charging

Hi,
I installed Arconium 5.0 onto my Xperia Arc LT15i, following this thread:
http://forum.xda-developers.com/showthread.php?t=1515148
I started with the Kernel:
http://forum.xda-developers.com/showthread.php?t=1680793
When booting into CWM, battery was ok, then I installed the firmware and after having finished and booted, battery showed 0% and the phone shut down when removing the cable.
I then flashed the Kernel again, no change, so I wanted to try the ArcKnight Kernel:
http://forum.xda-developers.com/showthread.php?t=1597771
because the version 4.1 link is not reachable, I went with the 4.0 one.
Everything seemed fine, the phone continued to work without power supply, battery level at 85%..but...it kept at this level, did not decharge and charging it made no difference too.
So I deleted battery stats in CWM, did not work, then I downloaded the App Battery Calibration and did a reset there, no change..
It keeps showing 85%, but that's not all.
I plugged my phone all night to fully charge it, after 2 hours of minimal use it sht down, and did not boot anymore until I plugged it into the charger again.
So either it is decharging REALLY fast, or it doesn't really charge.
Does anyone have a Kernel which is working with my configuration?
Thank you

I shut down the phone, removed the battery, put it back in andd rebooted, still no difference.
Then I removed the battery with power supply plugged in, the phone shut down immediately.
I then restarted it without battery, with only the power supply plugged in and it turns off after some seconds again.
Put in the battery again and rebooted the phone, still no change :/

Sounds like your battery is in bad condition - replace it with an brand new one.

Don't think that's the problem, before the update it had no problems at all, also yesterday a configured the phone during several hours without power supply. I believe it is software related, otherwise I would see the battery gauge vary, but it stays at 85% constantly.
That's why I wanted to know if there is another suitable Kernel I could test with, this one already made the battery go from constant 0% to constant 85%.

Wipe battery stats in CWM
Sent from my LT15i using xda premium

Tried everything, nothing works
I found some similar posts where the only solution was sending it back to Sony to get it fixed.
The issue seems to be hardware related when flashing back to firmware 2.3.2, which I had done accidentally by selection an old firmware in the flashtool directory.
So I bought a new phone (Xperia TX) and will send my Arc back to Sony.
Thanks for your help however.

maybe it encounter the battery problem like 0% battery? try use the Fuel Gauge Fix from Google Play made by Bazoocaze

[Solved]Red led light ,phone won't turn on

Well yesterday I flashed P.A.C Rom and when the device battery was on 0% the phone shuted down and after that I connected it to the charger to charge it again but I have a red light and the device doesn't reacts. Tried to to hard reset and everything but It doesn't helps.
Please help

I had this problem as well. You have to wait till your phone turns on (takes 10-15 mins) and boot into recovery. Flash another kernel with offline charging and it should work from there

Can you explain please which kernel should I flash?
Phone boots for 5 sec every 15 minutes and then it turning off again.

if you drained the battery during flashing to absolute 0% then it wont turn on immediately when you plug in the charger..wait for about 30minutes before starting the phone again..and dont flash when you are low on juice..always keep at least 50% battery :good:

Ok ,everything is ok now. I had another replacement battery so I used it and flashed stock rom on the device. After that changed to the original battery again and charged the phone offline.
