[Q] Intalling another Rom after Biftor Rom

Hello guys;
I use Biftor Rom 4.7 since couple of days.
I want to compare its performance with the other ROMs but i cant not flash another ROM (I've tride AOKP and Cynogen). When i do that it crashes.
Do you have any proposition?
Thanks

are the roms your flashing for your device?
if so have you done a factory reset and wipe cache b4 the new installation of newest RoM?
1 last thing have you downloaded the rom from your device internet browser? that has been known to cause issues

Yes i flash the roms after the factory reset and wipe cache.
I have downloaded the roms either from my pc or my device (samsung galaxy s2).
But i couldn't find any solution yet.

The usual way, you do all necesarry whipes, and then you install the rom you want. But: no dirty flashesas 4.2 and 4.3have eome architectural diferences (whipe sostem, whipe cache and dalvik, in mounts and storage format both sistem and SD card - better if you back up your photos, music and all media to pc as this deletes everithing you have on in), then connect your phone to PC/Laptop via USB and copy the files of the rom you want, the G-apps and/or kernel

Do I change the 4.3 kernel or ROM first to 4.2?

Always after full whipe and factory reset you:
1. Flash the desired rom (it has a kernel of it's own
2. Flash Gapps (they have to be Gapps for your specific rom android version)
3. Flash a custom kernel you like (if you will skip step 3 the rom will still boot up case it comes with it's own kernel, but if you downgrade it's good to flash one case the rom one is mostlikely outdated; and remember that the kernel you flash has to have suport for he android version you flash)
My advice to you if you downgrade is not to go back further than ICS case newer apps will probably have compatibility issues with really old outdated system versions

It was same Aex 6.1 . Is problem about vendors maybe?

Yes, they recommend a clean flash between roms because they are very different. Wipe System, Data, Cache, Dalvik and Vendor and flash the rom again - use latest official TWRP (3.2.3.1)

freezing issues. how to change rom without losing data

Hi, i am currently using syberia os latest version and is facing a lot of freezing issues. I have several multi authentication apps which is needed for official purposes and cant do a complete wipe of data! How can i install a new rom on top of it? Will a dirty flash of another custom rom will help it? What should be wiped inorder to avoid losing of apps/data of them mainly data inside MFA apps?

Can't you just backup your mfa? They usually have export options. If not, maybe apps like titanium backup.
Even dirty flashing on top of working roms is discouraged. Dirty flashing on top of a broken rom will probably leave you with a still broken rom
