I'm currently running Harmonia 1.3 and my V and am thinking of going GB. I can't find and good instructions on how to change over. I've got the Xionia .4 recovery already on my phone (which I like). Do I keep the Xionia??? can I use Xionia? do I have to change to Blarfs recovery? I'm using an older V not the newer ones with the Optimus S screens. I should be able to do the rest after I get the recovery on my phone.
If you already have flashed a ROM with no problems then you don't have the Optimus S screen(this seems to have been done on the refurbished "V"). To find out what version you have go to menu/settings/about phone. If you do as JerryScript mentioned you will not have to change your recovery.
If later you decide to change to asopCWMod recovery or Blarfs recovery then you should still keep Xionia on your sd card as it has an option in the advanced section that will fix a recovery loop.
Have you made a backup of you stock ROM in the recovery mode(this is called a nandroid backup),go to the backup and restore section and select backup.
To backup all your apps before installing a Gingerbread ROM you will need to download Titanium Backup and go to the Backup/Restore section. Hit the menu key on the phone. Select Batch.Select "Backup all user apps".
A good rule of thumb: flash_image and recovery's need to be unzipped. Kernels,ROM's,theme's,and boot animations need to remain zipped.
put the ROM.zip and Gapps.zip on the root of the sd card.
If you decide to use the asopCWMod or Blarfs Recovery then make sure the recovery is unzipped and on the root of the sd card(not in any file,but put it somewhere near the bottom of the list of file folders).
For ease of installation rename the asop recovery to asoprecovery.img that way you will be able to tell it from the xionia recovery you renamed vrecovery.img(you could also rename the xionia to xrecovery.img,and the asop to arecovery.img,which is what I did).
Once you have renamed the asop recovery then open up the terminal emulator and type in this:
/sdcard/asoprecovery.img(or what ever you decided to rename it to, just as long as it's spelled out the same as it is on the sd card)(return)
(use the same procedure for Blarfs recovery)
The red underscores are where the spaces should be, do not type them.
(return)=do not type this. Just hit the enter key(the one on the bottom right)
6. You should now be in your recovery. To scroll use the up/down volume keys. To select use the camera key. In Xionia recovery the selection key could be either the home key or the menu key(if you chose one and it makes your screen go blank,then hit it again and then use the other key instead).
To access your recovery in Harmonia use the power button to bring up a window with the recovery option in it.
Check in the back up and restore section and see if your backup is there(which it should be).
Now your ready to install the ROM and Gapps. Do all these things(they must be done or the residual data that's left behind because they weren't,will corrupt the ROM and it will act all funky,or freeze,or randomly reboot).
1.wipe cache partition.
2.wipe dalvik cache(advanced section)
(if your still using Xionia Recovery wipe cache partition and dalvik cache 3 times as JerryScript mentioned)
3.wipe data/factory reset.Now that your rooted YOU MUST NEVER USE THE FACTORY RESET IN THE PRIVACY MENU ON THE PHONE
4.format boot,system,data,and cache
5.go to install zip from sd card
6.go to select zip from sd card,chose the ROM first. It will go thru the install procedure. When done go back to step 6. and select the gapps.
When all this is done select reboot system now.
It will take 5-10min. for the initial reboot. You will be asked to sign in,skip this.
Now you can go to the market app and click on it and sign in to your google account(you must have your e-mail address and log in code). Then download Titanium Backup from the Market.Reboot the phone twice then set up your apps by going to the Titanium Backup app and selecting the Backup/restore option.Then hit the menu button on the phone.Select Batch.Scroll down to Restore and select "Restore missing apps with data"(use only this option,never restore a system app or data as this will corrupt the new ROM)
. Once you get everything set up just the way you like it and all your apps are just where you want them,go back into your recovery and make a backup of that ROM. You can now delete the first backup if you need to (you might keep it if you ever need to revert back to stock to sell the phone).
If you want to install a theme(I would suggest waiting to install a theme until after you have a couple of reboots on a new ROM) all you have to do is go into the recovery and wipe cache partition and dalvik cache,then do the same thing you did to install the ROM(theme must remain zipped)
When you need to install an update to an installed ROM,all you have to do is wipe cache,and dalvik.
To change the boot animation (must remain zipped) go to /system/media(make sure that you have changed permission of the system from r/o to r/w) and delete the boot animation found there. Then copy the boot animation you have on the sd card and paste it where the old animation used to be(on next reboot it will be there)
