You have bricked your phone. There are a few tutorials in the all things root section that may help you.

 

First never call VM about problems when your phone is rooted. It always leads to more problems.

AceofSky: Things are not as bad as they seem. If your stuck in the recovery you golden.
Go to the sticky at the Top of this forum: "Do not Factory Reset your Rooted Phone" read the first page.

I think the download link to the zipped recovery you need is wrong so go here: [FIX]Black screen with custom recovery and custom roms - Android Forums at AndroidCentral.com at the bottom of the first post is the zipped recovery you need. There willl be an small image and then "Xionia_CWMA_12518.6_VM_Recovery-signed.zip (4.83 MB, 1627 views)".

 

I think you are on a stock recovery now....what does the main menu say?

 

Yes you need adb, follow this: http://androidforums.com/showthread.php?t=368034

 

Did you try turning signature verification off?
In your recovery when you select "install zip from sd card" the next options screen there is an option to toggle signature verification.
Select the option twice. This should turn off signature verification.

If that don't work you will have to flash it with ADB.

Go here: New pre-packaged ADB installation if after typing in "adb devices" it doesn't give you the proper output then follow the rest of the guide and the link. This will show you how to put the path to the adb.exe into system path of your PC.
Download a MD5 sum checker to the PC and download the Xionia recovery.img found here: [Custom Recovery] Xionia Clockwork (CWMA v1.2518.6) - Android Forums at AndroidCentral.com
Put the Xionia recovery.img (renamed recovery.img) into the C:\SDK\platform-tools folder (this is where the adb.exe and the fastboot.exe can be found)
[Custom Recovery] Xionia Clockwork (CWMA v1.2518.6) - Android Forums at AndroidCentral.com.
Then open a command prompt and type in this:
cd..
cd..
cd SDK\platform-tools

Then go here: [FIX]Black screen with custom recovery and custom roms - Page 6 - Android Forums at AndroidCentral.com

EDIT: there is a small error in his code which will cause an error after you type it in and hit enter.
The xionia_cwma_1.2518.6.img in his code doesn't have a . after the first 1. Make sure you type in the .

 

The MD5 sum checker just lets you know if the downloaded file is OK, or it became corrupt in the download process. Try this one: MD5 Checker - CNET Download.com It's as simple as it gets. When you are at the developers page of something you want to download, copy the MD5 sum they give by holding the cursor over the MD5 sum they give starting from left to right. Left click and hold while moving the cursor over the MD5 sum, it will highlight it. Then right click on the highlighted part and choose COPY. This will put it on the figurative clipboard of your PC.
Once the download has been completed go to where you put the MD5 some checker.exe and left click it. Now choose the downloaded item. If it is a good download it will say that they are a match.

Opening up a command prompt can go two different ways depending on your OS. I have a Windows XP and had to download a program from Microsoft that puts the option in my Right Click pop up window.
For Vista and 7 you need to place the cursor over the folder and hold control+shift and then right click the folder.
The other way to open a command prompt is to left click the Start in the lower left corner, then in XP select Run from the list of options and type in cmd then hit the enter key. If your using Vista or 7 go to the Start and type in cmd in the box.
The easy way if you are having problems is just to type in a command prompt:
cd..
cd.. (this will get you to the root of the C:\ drive)
Then type in cd SDK\platform-tools (this is where you put the recovery and where the adb.exe and the fastboot.exe are located).

Then follow the rest in bigsupersquids thread.

PS: I hope I broke it down enough, if not keep asking questions.

 

^+10^12

I'm quoting this anytime someone doesn't know how to use cmd.

 

You forgot to put the point in after the first 1 in the name of the recovery.
It should read: xionia_cwma_1.2518.6.img not xionia_cwma_12518.6.img

I put that note/edit in my second to last post at the bottom.

Not to worry, just put it in exactly as it is spelled on the sd card (my note mentioned an error in bigsupersquids code, first and only time that ever happened)

 

Rar file? You need to extract the RAR file......

 

sammyz is correct.
I had someone tell me the site no longer had a .zip or .rar form of the xionia.img. Took their word for it instead of actually downloading to verify. Just did so. It is in fact still a rare file and needs to be extracted. 7zip works very good for this. Once extracted then rename to what was mentioned.

 

Maybe you could be more specific. Explain exactly everything you did (in detail) from the time you downloaded the .rar file from the Xionia page till now.
It should open, there must be something your missing.
Note: Did you try to toggle signature verification off before flashing the recovery.img?

 

I need help please. I have an lg optimus v. I factory reset it and got stock in cwm recovery. I have tried exitrecovery.zip and cwm_bootloop_fix.zip but I always get the same message: E:Error in /sdcar/cwm_bootloop_fix.zip (Status 0) installation aborted. I have tried to use different sd cards, taking battery out, pressing down volume key and power at the same time. i also tried adb but no matter how many times i try i can't install properly the drivers for Android Sooner Single ADB Interface. The message i get is: Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52). I tried redownloading the drivers and installing them again. I have tried turning my computer on and off. I and literally out of options. If i can't get get help i'll probably give up. Any help will be greatly appreciated.

 

You where supposed to put the xionia recovery in the same folder the adb.exe is found in not on the SD card.
This is the only way it will work. Don't ask me why, it just won't work any other way. You have to push the recovery to the sd card.

You don't have to paste the commands in, you can just type them into a command prompt. You also have to open the command prompt in the folder the adb.exe is in or open a command prompt and type in:
cd..
cd..
This will get you to the root of the C:\ drive.
Then type in:
cd SDK(or whatever the name of your SDK folder is)\platform-tools(or whatever folder the adb.exe is found).
