turn the phone off. HOld down vol down. Connect the phone to the pc while holding vol down. That should get you in download mode. If it doesn't hold down both vol down and up buttons and connect to the pc.

Pressing once does not turn it on. You need to hold it down for few seconds, til it vibrates. Then you can release it.
I do this but wont power on. I dont know why.
Its recognized on my computer as qualcomm usb or zeus flash device.

It's soft bricked, you need to recover your phone with Sony Update Service.

You won't need to power on your phone for this. Install Sony Update Service on your computer and follow the instructions given.

Ok I will test, thank you.
To turn off phone, take out battery (just to be sure)
Put battery back in.
Follow instruction from sony update service.
Press and hold back button first. Dont release
Now connect cable.
Should work now and update service will do its stuff.
Thank you guys but
It work, green led and updates loading, phone detected as s1boot download.
I unplug the phone and hold power button until vibrate but nothing
Now when I plug phone on the pc, the computer detect qhsusb_dload device
what is the problem ?
That is strange. I am running out of ideas to help.
Last idea is to use Flashtool and flash a stock GB/ICS rom.
Use this thread for all instructions and download links - http://forum.xda-developers.com/showthread.php?t=1642480
I forgot if flashing by flashtool requires to have unlocked bootloader.
Ok thank You
I will unlock the bootloader and then flash the phone

1. Turn off your device.
2. With the device turned off, press and hold the Vol UP + Power i think or Vol Down + Power and Factory Reset should appear.
3. When in the menu press POWER again
Have been trying and cant seem to get it... ive been wondering how to get into download mode as well cant seem to anymore after installing cw,m
Download mode vol up +vol down same time. Keep hold and connect usb cable. When see downloadmode release vol up and down

Anyone can guess a reason that factory reset wouldnt work? it just boots in to bootloop with power + vol down.

But your phone just connect with your phone by flashmode,not fastmode,you want to gonna fastmode,you need to shutdown your phone,and press VOL+,and then connect with your computer.Just do as what forumer said.Don't mixed.If you want to install the customer rom,you need to unlock your cellphone.Remember you need to go the following step:
1,root your phone,
2,unlock bootloader(fastmode)
3.install the recovery.(fastmode)
4install the kernel from the rom.(fastmode)
5install the rom.(recovery)
6reboot into the phone

power&VOL+ gonna fastmode,power&VOL- gonna flashmode.Seams the driver is different.If you unlocked the bootloader I think your fastmode driver is installed.And whatever of mode you went in,you must power down your phone.not restart.

I didn't get it but i tell you no response with any other buttons neither vol- or power on by itself
I only wait while charging till sony logo appears by itself without pressing buttons then i try everything and the only positive response i get is :
as i told you ( power & vol + ) ----> goes into flash,mode !!!

Can anyone help me install stock 4.4.4 rom on D5103?

I saw a guide on xperiafirmware.com or whatever its called, but I dont understand the step where it says connect the phone to pc with holding volume down button. Do I hold the button and connect it at the same time or what? Thanks in advance, I'm a noob at these things so dont be harsh please

Hi, idk if this is still relevant, but yes, you hold the volume down button and keep holding it as you plug in the cable.

Samsung Galaxy A50 Issue after Update

Hey People,
maybe someone of you can help me.
I made a normal Update of my Phone 5 days ago after the Update my Phone went off and now it shows a Blue Screen with the Information that something went wrong while the Update.
I tried to repair it with the Smart Switch Pc Software but it don't worked.
I gave it to the store where i bought it but they want that i pay for the fix. Honestly i didn't tried to root it because i needed it for work.
Had someone that issue and can help me how i can fix that by myself?
Kind Regards
Saint
yes you probably can fix it easy
connect your phone to a pc with the usb cable
hold vol- and power to force the phone to reboot.
when the phone shut down, rapidly hold vol+ and vol- .the phone should enter download mode
use odin software to upload the latest firmware of your phone
download mode

That's because only the first part is needed. Just turn off your phone normally and then turn it on simultaneously pressing Volume Down and Power.
It finally worked after....

Thanks for your reply. I did as you suggested but that gave me a normal boot. I tried as someone else suggested, pressing power+UP volume and that did finally get me to recovery mode! Played around with that for half hour
Thanks again! Now if only can get the transfer working in OTG!!!
