[Q] Flashtool not get into flashmode

I've tried to flash "LT15_LT18_70_Baseband.ftf" on Arc phone using flashtool 8.0.0 x64, flashtoox64.exe.
I pressed flash button and check flashmod and OK, select "LT15_LT18_70_Baseband.ftf" and selected all sins and ok. Then I got usb connection guide screen and I plugged usb in arc as described at usb connection guide screen.
But the "usb connection guide screen" didn't disappear and I got these logs at flashtool application.
Please connect your device into flashmode.
- Device connected in fastboot mode
INFO - List of connected devices (Device Id) :
INFO - - USB\VID_0FCE&PID_0DDE\CB5A1FWGV2&ZLP Driver installed : true
INFO - List of ADB devices :
INFO - - none
INFO - List of fastboot devices :
INFO - - none
INFO - Device disconnected
And I tried usb connection with "flash.exe", then I got this attached picture, and still the "usb connection guide screen" didn't disappear as shown in the attached picture.
Please let me know how to connect my arc phone into flashmode.
Thanks in advance.

Have you put it in flash mode? I.e. Turn off the phone hold the menu button then connect the USB?

No, I pressed "Back" button as described at flashtool.

Press and hold.

Yes, I pressed and holding "Back" button I plugged usb.
But still flashtool shows "INFO - Device connected in fastboot mode".

Phone should be in Mass Storage Mode (MSC) and you need to switch off your phone. Press and hold Back when flashtool tells you to do so, plug in the USB and release Back only when instructed.

xtacy!/ Yes, I checked MSC, and pressed and hold "Back" button when the guide picture appear.
I also tried at safe with networking, but same result.
" INFO - Device connected in fastboot mode "
This log was loaded.

Try using Media Transfer mode.. To be honest, i never used MSC mode in my lifetime while flashing with FT and has always been in MT mode..

Same here. I've never really used MSC mode. I prefer MTP. But the instructions say to use the former. Oh well.

gire.prasad/ Thanks.
I changed twice, then it works.

If it tells you you're on Fastboot mode, then it's not the correct key you're holding. If it needs flashmode, your led should turn green, if it turns blue, it's on Fastboot mode.
You can try this by powering off your phone and trying holding down keys until the green led is on. (Dunno which one is for Arc, I have a Pro).

[Q] My Phone Charges, But Won't Turn On!

I just got a Sony XPeria Play from Ebay, and it doesnt turn on, ive charged it, but it doesnt vibrate or anything. But it does charge perfectly fine. Please could I have some tips? PC Companion won't help and I have taken the battery out and put it back in countless times.I also need some help with fast booting my phone

How can you tell it's charging?
Are you using USB to computer or USB to wall?

I can tell its charging because the screen goes to the charging icon, and I'm using usb to computer.

If you hold the search button while its off and conect the USB to your PC does the power button light turn blue? If so you can try flashing back to stock rom.
Or if you hold the back button and connect does it turn green?

Yeah it does turn blue, but the power button doesn't respond to me pressing it...

remove the usb and make sure everthing is off, now remove the lid of the phone and press the power button. Remember you have to leave it press a couple of seconds

I've got a feeling the power button is stuffed... It still won't do anything when I hold the power button

i would also think is the power button, cause if you hold the search button and plug the phone while it of and the led on the power button turns blue, and if you hold the back button instead and it goes green, i would say that the power button is definitively the problem

Ok..don't press the power button if you're trying to put it into flash or fastboot mode. It sounds like it's one of two things: 1. the button itself is not making contact OR part of the board is busted. Either way, if you have flashtool then hold back and plug it in the usb, flash the stock ftf and flashtool will boot your phone for you.

I hope its the former! Also when I turn on flashtool, it says I need drivers, where do I get them from? Sorry for my nooby questions.
EDIT: Found the driver installation file, now I just need a stock ftf

It's ok mate don't worry, it's not being nooby
Here is the link for those drivers:
https://rapidshare.com/files/1146432065/Flashtool-drivers.exe
Install it fully, so once you open it click next and tick all the boxes. I know some are useless but just incase select all. Thats what I did It will take a bit of time I know and messages keep poping up and just go along with and it will eventually finnish. I had this problem too.
You can find this driver installation file in the directory of flashtool aswell.
It should be in -> C:\Flashtool\drivers or something like that.
Good luck

Ok so I need a stock ftf file...

Mybe u should jst try reboot using command prompt 1st. Jst to be sure that is related to the power button or not. Install all driver. Mke sure the phne is off, hold the search button n connect to the pc n see light turn blue. After that open command prompt n type "fastboot reboot". If it reboot then u'll know its the power button related.
Thanks vokal1992

Do this:
1.- Open flashtool
2.- Hold the search button on your phone
3.- Connect usb cable while holding the search button
4.- In flash tool press the lightning icon
5.- Select fastboot mode
6.- Select Reboot in system
7.- Enojoy

Hmm, now I'm thinking it's a broken battery, because it gives up on me as soon as I unplug...

Unplug it after it reboots

It reboots into the charging thing and when I unplug it, it dies.

in flash tool, does it say connected in fastboot mode?

U need to enable the usb debugging to be able to reboot using flashtool. Mybe the easiest way is to flash another stock .ftf.
Thanks vokal1992

well, if you need to flash ftf heres a list of them:

I think your phone hard bricked !
In this situation if you couldn't reset your phone by holding power+volume up till it 3 times vibrate , try power+volume down when you connected to pc sometimes it reset your phone.
try power+volume up when you plugged in wall charger till 3 times vibrate ( in some situations it happens after 30 second you hold both.
If none on this reset your phone , its only way that you send it to repare service of sony to re write your bootloader by JTAG box. I had the same problem when I install an improper kernel and I search all of net and try all thing I found but after 2 week I can't solve the problem and only way to back your phone to work is, re writing your bootloader by JTAG box

Anybody can help? maybe trim area problem??

that happened to me once. I removed the battery, connected the wall charger, and then put the battery back. It was the last thing I tried and it worked.
(Yes, I had to open the phone, so I don't have warranty)

1-Download first Android SDK
2- Open device manager in windows
3- Connect usb cable to your phone pushing vol up button
4- Device manager will show you fastboot device for 2-3 sec (before the phone goes to charge mode). Right click on fastboot device and install drivers from C:\Android\sdk\extras\google\usb_driver
4) Reconnect usb cable pushing volup button

Make sure u have installed proper drivers... and the port you r using must be usb 2.0

i have same problem any solutions ?
i have drivers installed and usb 2.0

Google 'flashtool drivers' and install the drivers. This works for me.

That is another way. You can just navigate into flashtool folder and search for driver setup and install the fastboot driver

Type your command and press enter will show waiting for device
Then connect the phone in fasrboot
The command will be executed
Try this. Hope it works
