hello, can you please help?

same problem, only red light, 3 red blinks when trying to turn on.
first i tried other software solutions from another forum, no chance.

then i tried hardware solutions. with the battery disconnected, and plugged the phone in charger. it showed on screen battery icon and charging for a few seconds and then it restarted. and nothing more.

then i tried your solution but i think i made a mistake. the phone will not blink 3 times red when battery connected and trying power button like before. and with battery disconnected, charger connected, lcd lights up but nothing is shown on screen now. i don't know what to do

Oops,disconnect battery tell you post the pictures.
Do this fast as fast not damage the phone because it seems it is a short between gnd and vbat.

sorry for bad image. this is the best i could take with another phone

at first try i didn't solder only the big contact, there was no connection with the small capacitor.

i had the connection redone by a professional guy and this is how it looks now

phone is not starting, when plugged in computer, pc companion recognizes the phone and gives me a message to disconnect and power on the phone but that doesn't help.

also, when holding power and volume up, there is no reset, it does not vibrate 3 times



i'm not sure why the image is not loading, here is the link http://imgur.com/RqMwwcd

<< more info >>

when plugged in the computer, nothing happens for about 1 minute, after that the lcd backlight lights up, but without image and a blink of red led lights up behind the speaker. after this the pc tries to install MTP USB Device, another 3-4 seconds and the phone restarts and the process begins again... lcd backlight lighting up, no image on display, red led, driver install in pc

the only way i can stop this process is to unplug the battery connector from the motherboard

[ahmed koukou]

It maybe battery voltage is too low.

now it has been about 1 hour charging, still no response.

with battery disconnected from motherboard i tried to flash a ftf file and flashtool did it's job very well. so the software can be changed.

but still no response when trying to power on

[ahmed koukou]
