You can do it both ways, you should not be needing a full system wipe, only dalvik and cache wipe. Depending on your current rom and changes you have made you can opt for kernel only or full rom flash. Data and apps should stay intact, but do a nandroid backup just in case.

Help needed--Custom ROMs, Bootloader??

hi everybody!
I need an help. Sorry for my bad english, I'm only 16 and I'm Italian.
I have an Xperia Mini, it's my first android phone, so I'm not very good at android modding! I downgraded it from ICS (Official) to Gingerbread (4.0.2.A.0.42 build) and I rooted it. Then I installed ClockWorkMod recovery. I don't have an unlocked bootloader, but I want to flash a custom ROM based on gingerbread. If I flash it, can I go back to stock rom with CWM's restore function? And If I can't, can I use flashtool to flash it (I have the .ftf file that I flashed for downgrading)?
Thanks very much.
Welcome to our forum
You can flash a gingerbread custom rom for locked bootloader with cwm, but be sure it is for locked bootloader!
If you take a backup in cwm, with backup/restore -> backup before you install the custom rom, you can restore this backup to go back to stock. Flashing the stock ftf will also work, you have to decide if you want to restore or flash, but if you take the backup in cwm it will backup the whole firmware with all apps etc :good:
Thanks! :good:
But do I need to flash a custom kernel? Or can I keep the stock kernel?

For locked bootloader custom roms it's the stock kernel :good:
For unlocked bootloader roms you need to flash a custom kernel, but this is only possible on unlocked bootloader

but the description says..."it should work with any ICS kernel...I currently have this kernel...2.6.32.9-perf [email protected]#1
can I flash this ROM? And if my phone gets Briccked, can I repair it with CWM or it won't boot into recovery?

Normally it should work, but the problem is there's not specified if it is for locked or unlocked bootloader. It's stock based so it could work on locked, but it is recommend to flash a kernel. You could try it, but it could be you get a brick
When it's bricked, (mostly) you can't boot in recovery so you have to flash the stock rom with flashtool
Another little advice: If you install an ics custom rom on a gingerbread phone it could end in a brick. I had this when I was on locked bootloader, so I updated to ics (while keeping root, how to do this is in my rooting guide) and installed it again.
You can try an ics custom rom on your phone running gingerbread, just install it. But if it won't boot, flash the stock gingerbread rom and update it with root to ics
Ok. But before installing a rom, I have to do a full wipe, and wiping all will delete the CWM recovery?
I think I'll first upgrade to ICS officially. Can I use pc companion? or I have to flash the .ftf file of the stock 4.0.4 firmware with flashtool?

1.) make nandroid backup
2.) factory reset/wipe data
3.) wipe cache/partition
4.) format system
5.) wipe dalvik cache and battery stats.
6.) flash ROM
7.) flash supersu fix, there are lots of links out there just incase you have problems with root. this will solve your problem if u have locked BL
8.) if you lose CWM, you can use led deletes x-recovery tool to install cwm after you boot your rom
BUT TAKE NOTE THAT THERE ARE CERTAIN THINGS YOU MUST DO IN "SOME" Custom ROMS like Hasa(flashing lockscreen after 1st boot)
MAKE SURE TO READ THE THREAD's INSTRUCTIONS FIRST
Ok i read all the guides...now I'll update to ics and root it. Then I'll install a custom rom.

I have unlocked bootloader. The man who had phone with locked bootloader and tested the rom, said me that everything works OK.
Sory for misinformation. I deleted CWM from description in OP.

Nothing special. Just make sure you do a full wipe before flashing.
