[URGENT] Return to Stock Rom [Xperia Ion][Unlockable Bootloader] - General Topics

Hey Everyone,
Please Help Me With my Problem.
Today Only I Installed MIUI Rom on My Xperia Ion (Rogers Canada). but found it little bit buggy so I wanted to Return back to Original Rom.
I Tried Flashing Stock Firmware using Flashtool but soon Found my Phone has Unlockable Bootloader, So It Won't be able to Flash.
I Tried Repairing it USing Sony PC Companion But Still it won't go into Flash Mode (Fails at the Step when They Ask to Switch Off Phone, Then Keep Volume Down Key pressed and Plug The USB---Nothing happens Here)
SO any Help?

[Q] Xperia Ray st18i booting prob ..

Guys , I was on Jelly Sandwich with sirikay's kernel. I had some speed problems with wifi. So I thought of flashing stock ICS Rom ST18i_4.1.B.0.587_Kernel.ftf using uniflash.exe and did it. After flashing it didnt restart. So I clicked the power button to restart manually but just got a vibration sound and nothing else .. just the blank screen. So I searched for stuff about unbricking my device since I thought it's bricked. I downloaded this package "FlashTool_0.2.9.1_FOTAUnbrick.exe" and started flashing the firmwares. So I held down my volumedown button and connected it to the usb port. It says error and that I have to select usb debugging mode and connect again but I can't even start my mobile.
Plz help .. Thanks in Advance
Try using flash tool!

Hi
I confirm, just had the same problem while updating a custom ROM.
Get the Stock ftf file for your phone/model then use Flashtool to flash it.
Search the forum for the proper links there are likely to be all there somewhere
Hopefully, your phone will be back to life on a stock version.
And yes, if you want to re-install a custom ROM you need to re-do all the process: root, (optional) unlock Bootloader etc.
Good luck.
PS: I saw a thread saying to use the SEUS to restore the phone to stock. Worth a try but for me it didn't work since SEUS was telling my phone already had the latest version. Fix hard bricked ray

Appreciate any help possible fixing this phone paid alot of money and I'm disappointed Sony won't fix it
Try if you can get it into flashmode.
Hold the vol down and connect it to your PC while holding it.
It should start into flash mode (blue LED if I remember correctly) and in the PC's device manager a new device should pop up.
If it works you can easily reflash a official ftf with Flash Tool.
