This custom rom is compatible with lock bootloader now...so I wanna test it out...does anybody with lock bootloader successfully installed this rom and between ExMIUI and MiniCMSandwich Lite which one is better in your opinion...
Thanks.

I tried them both yesterday, just to get an idea. No problem at all with my locked bootloader. Anyway, since I only catched a glimpe of both ROMs, I can't post a real review. You should try them both and decide if you like them
MIUI is more... mmm... i-phone style. MiniCMSandwich looks like a Galaxy Nexus

You got bootloop and fc's as you did not clear data.
@Till: these roms will have no problems to run on locked bootloader. As the ROMs are compatible with the stock kernel.
To revert back you need to restore the back up using CWM. In this whole flashing the zip and reverting back process, you just are making sure that you do not touch /system. That way, you do not mess up with nAa's CWM (its installed in /system only), and so everything will be fine.
In case you get a bootloop, just flash the ROM again by flashtool, or repair using PCC and all will be fine.

See, the nAa's recovery installed on locked bootloaders are installed on chargemon and charger files which are there at /system/bin of your phone memory.
Now, suppose you install a ROM which is based on the Stock Kernel. To do this you flash the zip you got from xda or somewhere. While this zip is being flashed, the /system files of the stock ROM are replaced by the /system files of the ROM you are flashing. This will cause the chargemon and charger files to be overwritten, and so, CWM messes with itself. And rest of the installation will fail, giving you bootloop or brick.
The kamarush ROM, which is supported on locked bootloader, takes care that it doesn't replace the /system. Thus, nAa's CWM remains intact, and you can successfully flash the ROM.

Not true. Before installing the ROMs, you NEED to wipe /system. You can do it via CWM (Mounts and storage, wipe /system, /cache and /data. Then Wipe dalvik cache in advanced settings). Otherwise, you'll end up with a lot of fc.

Yes, restore nandroid and that's all. About /system, I already explained that

When you are doing a /system wipe using CWM, then CWM knowd how to protect itself. It will not delete the contents of /bin and /xbin files.

Of course
What I meant is that you HAVE to touch the /system folder. Just touch it the proper way

Yea. Right. You are correct. In the first post where I mentioned not touching /system, I meant that the ROMs which have been made to work with locked bootloader make sure that they do not touch the /system. The zip files have no instruction about clearing data. So all data has to be cleared manually using CWM, and nAa is clever enough to make sure that his CWM knows how to protect itself. . (I sometimes so badly wish that I had the brains of Kamarush and nAa. I could look at the smali code and know what it means. With my current brain, I have to spend a whole week to figure out what's what, and then editing is a separate story ).

Yo HAVE to wipe /system, because the current system will conflict with the new system.
In nAa CWM you wipe the whole /system (with /bin and /xbin) while it's running, and after wipe if you restart you will stuckat SONY logo, so don't reboot just install from zip. It will start Aroma installer and before the installation you have. to choose the locked bootloader version.It will install the ROM with nAa's CWM and now you can reboot and enjoy the ROM.

0. Get ROOT and install CWM. -> Only for Locked Bootloader
1. You must do a Full Wipe in CWM (System/Data/Cache/Dalvik-Cache)!
2. Copy the ROM to your SDCard
3. Flash ROM in the Recovery
4. Reboot & enjoy
5. First boot is loooooong
I don't get it in no. 1

I already told you. Start CWM Recovery on boot. Go to "Mounts and storage" and format /system, /data and /cache. Then go back, head to advanced settings and clear dalvik cache. Then install zip.

Here's what he meant.
You just clear everything (in kamarush's thread it's mentioned) and then you do not go for a re-boot. You directly choose the zip you downloaded. Now the zip will ask you if you have locked bootloader or not. If you select locked bootloader, the ROM installation will start with the installation of CWM (which you had cleared along with everything else), and then rest of the ROM will get installed. Then reboot, and everything will be fine.

I can't agree on this point. You are using CWM to flash the zip, so CWM is still there
