Hello, Boss!

Nice to see you here..

But I did everything you guys said...also i tried every post about this RED light situation topic.....

but i am stuck with now-

I can notice when phone getting bootloops.....

after finishing 48(hours) wall charging without touch .... there is no GREEN led ..

FASTBOOT------

When I press the FASTBOOT button

Volume UP with USB connect

after sometimes RED led appear and standby. (PC gets nothing/neither FlashTool)

when my finger gets hurt after 2mins off holding down Volume Up button there is no response.

I disconnected the USB from PC

RED led gone.

and again i tried this way...

now this time without getting FASTBOOT (BLUE led) when i disconnect the USB cable from PC

RED led still there......and....after 5-6mins phone goes DEAD. (everything off)

still disconeected from PC ... from this situation till 10-15 mins later RED led appear and stay like 5-6mins.

----------------------------

FLASH MODE------

When I press the FLASH MODE button

Volume DOWN with USB connect

after sometimes RED led appear and standby. (PC gets nothing/neither FlashTool ready with stock kernel.ftf)

when my finger gets hurt after 2mins off holding down Volume DOWN button there is no response.

I disconnected the USB from PC

RED led gone.

and again i tried this way...

now this time without getting FLASH MODE (GREEN led) when i disconnect the USB cable from PC

RED led still there......and....after 5-6mins phone goes DEAD. (everything off)

still disconeected from PC ... from this situation till 10-15 mins later RED led appear and stay like 5-6mins.

-------------------------

IS there anything about DRIVER with my PC issue?

i am using Windows 7 32-bit SP1

with all drivers installed.

get all kind of ADB/Google-USB drivers from SONY website/Flashtool drivers.

in device manager i get some Driver Signature ISSUE........(Yellow mark on Driver's Left side on DEVICE MANAGER)

is this any problem for getting not connected??

-------------------------

How can i GET the proper ADB DRIVERS for Sony XPERIA SP device.

i searche....but

everywhere till S, SL, SX, Z, Z1, ULTRA.....etc...etc..

but i can't find any SPECIFIC driver for XPERIA SP device.

now i am using latest ADB driver sa0109.inf file from z1-ultra device driver page from Sony Webpage.

Thank you very much...MATES!!
