[Q] What will I lose by flashing a custom ROM?

I'm thinking of flashing markphyton's ICS Firmware using these instructions. I'm currently on stock 2.3.4 firmware. What data will I actually lose if I flash this ROM?
Thanks.

Everything but SD card contents

If you backup everything with titanium backup you lose nothing.... Be sure to save your contacts in your SIM.

Problem is is that my firmware can't be rooted so I can't use Titanium backup, any suggestions on how to get around this? About the contacts, does Google not save your contacts info to your account?
Can I somehow root my phone considering the fact that I'm on the latest stock GB ROM?

Search a sms backup tool if you want to backup these, and use AndroZip to backup all your apps if you dont have root

So, contacts are sorted then. How do I backup my apps and restore them as they were on my previous ROM after I've flashed the new ROM?

Backup apps with titanium backup, download and open the app on the other rom and restore everything.

I'm on the latest GB firmware. Is there any way to root this so I can use titanium as the stickied methods on the forum say that they don't work with the latest firmware.

You wanna root your phone?
Which device?

Well doom kernel from what I have herd is about the best GB kernel but I may be wrong... it also has pretty simple step by step that you can follow and lupus GB is also pretty good but when you flash make sure that they are for GINGERBREAD devices not ICS or JB.

Wait. Won't flashing a new kernel mean that I will have to wipe the phone? If so, that won't work as the only reason I'm rooting is so I can use Titanium backup. Is there any way to root it without wiping the phone?

You have to flash a fresh copy of stock rom using flashtool. You cant get rid of root.

Actually you can unroot using super one click root. It has a root and unroot button that does it for you but i havent tested unrooting yet because i dont know why youd want to though it rooted fine so i think it should work

Yes, flash the MJ5 bootloader to avoid any problems. And make sure that you have the latest CWM version. I personally recommend TWRP, latest version also. You should be set with that.

Well, finally we have got KitKat and so I may ask, why you want to go back?
If you want to run 4.3 custom roms, no need to downgrade, go ahead and flash.

flash ofw with odin then flash cwm and restore backup. it worked for me

People are saying you can't flash back to 4.3 from 4.4.2, which is partially true.
Even when you flash the 4.3 firmware, you will still have 4.4.2 bootloader.
However, if you are not really fussed about the mini details, just flash it like you would normally with Odin,
then when there are problems with wifi, use custom kernels to fix it.
Otherwise, flash 4.3 then use a nand backup to restore (if you have it).

Just using odin 1.85 to flash back to 4.3 stock rom. Remember to wipe data/cache before flash
I hope this can help.

If bootloader only, nope. you won't lose them.
You already know what bootloader you're going to install?

Thanks for your reply. I think i start with the MJ5 bootloader
So it's totally save to load this bootloader with Odin?
After that i make a backup with TitaniumBackup

Thanx for information dude ! ?

MJ5 is a good choice since you can install 4.1.2, 4.3, or 4.4.2 roms.
But for KK roms, offline charging is not working.
Goodluck.
