[Q] - Hardware Hacking General

Hi. I have a Sony Xperia Arc S and it doesn't turn on. I tried the PC Companion but still I can't open my phone. Please i really need your help.

Is this the first time you are trying to boot your device?

Plug it on the wall charger, and you will have to wait a couple of hours, it happens to sony devices, the phone needs to charge the battery, it's a weird issue.

help me to revive my phone

Please help me, my phone is Atrix 4G, to unlock the phone two days ago when the phone can not boot. Installing the battery press the power button nothing happens, remove the battery, plug in the power only the green light in the light. How should I do?
Google how, to charge your phone without a charger, you will have to sacrifice a usb cable. After you put a charge on it, reflash a gingerbread sbf file. I suggest the 2.3.4 pudding full sbf since you want an unlocked device.

thanks for your advise ,but when using a USB charger, the computer can not find the device, and I did install the correct driver.

What I suggested involves cutting the end off a usb cable and manually charging the battery with an electric current, if you would have searched there are several YouTube videos that show you how to do it.
If the phone won't start with a charged battery then you have no way of fixing it.

Try to borrow a battery from a friend who has a atrix or Droid X instead

n7 just died, how can i wipe data before exchanging??

My N7 just randomly died. It's been working great for a month and now suddenly won't turn on. The battery was very low and it probably shut down from that. But after plugging in to recharge, nothing!! No power, won't turn on, has no indication it's charging ... totally dead. I bought retail but if i return it now, my data is not wiped. I'm afraid that after i exchange it, anyone either at the store or at google/asus that gets it back and gets it turned on will have access to all my accounts.
any suggestions?
does it connect when you plug it via usb?

It's 100% dead so it doesn't connect at all, not power not usb. Very weird, it's had zero issues until now and it just randomly died ... no trigger
Since you didn't provide info on how you were trying to charge it...
o are you using the OEM charger and cable?
o how long did you let it charge (let it go a couple hours)
o When you try to start it up after letting it charge for a while, press and hold the power button for a long time 30+ seconds
If you can't get it to ever power on, you will never get the data off since that is the only way to access the memory on the device.
I'll just leave this here...

same thing happen to me in my samsung galaxy y and the problem is the battery, try to replace your battery
Have finally noticed what is happening..
Phone stops charging few times a second...
Have noticed it when it was making low battery sound when charging from 2%...moving cable around did not help at all so it seem it is not USB socket in the mobile.
Same was happening this morning after I came to the mobile to unplug it from charger...don't have other cable to checkvif it is cable problem...but it doesn't happen all the time...

Nexus 7 Issues

It's weird, it only charges when It's off. But, when on it acts like It's not connected to the charger. I've tried factory resetting. It also won't connect to my computer, simply because it won't charge. I've searched here and I haven't seen a problem like it. I can still charge it when It's off.

Hi ,
Do you charge it by OEM charging cable ? If so , you should use another cable and try charging by new one.Unfortunately , the OEM cable has problem with charging the device.
More info please. Are you rooted? What ROM/Kernel? Did you make any changes lately? When was the last time it worked right?

[Q] nexus4 4.4.3 update charging issue

Hello smart people... So I updated my nexus 4 to the 4.3.3 version and now it just won't charge... It has been connected to the wall charger for 6 hours and still 34%... Please help!!! Also I have absolutely no tech knowledge... So easy instructions please???
It doesn't make sense that the update would cause the phone not to charge. If try a different charger or a pc. See if it'll charge then. If it still doesn't then I'd try reflashing the factory image
