Half Dual Boot 4.31OFW

Hello, I'm new to this and I have some questions. I was thinking of doing the fast dual boot but then I realized it would be too hard given that I don't have much experience with soldering. So I guess I'll have to settle for the half dual boot.

My PS3 is CECHH, motherboard is DIA-001, original firmware version is 1.xx. Current installed firmware is 4.25 OFW. I have E3 flasher limited edition and E3 card reader.

1. I want to be able to play backups and play online on PSN (so 4.31 OFW). Hence the need for dual booting. Is such a thing possible?

2. Most tutorials I read have upgrading the OFW as a first step (before installing the e3 flasher). Since my ps3 has 4.25 OFW and I need 4.31 OFW to play online, is it ok if I update the OFW after having installed the e3 flasher? I'm asking this because my PS3 is already disassembled.

3. How slow is half dual booting? Would you recommend it or does it run the risk of bricking the PS3 because of having to upgrade/downgrade everytime I want to switch?

Thank you very much

OK, I have managed to install the e3 flasher, and my dumps seem valid (still awaiting confirmation). I am on 4.31 OFW.

Tomorrow I will try to downgrade and install a CFW. I still want to have a half dual boot setup. Right now I have 2 HDDS, the two of em with 4.31 OFW. I'm looking for guidance on how to achieve this with as low chance of bricking as possible.

I've been doing alot of reading to try to figure this out, one post that attracted my attention is this one:

for explain:

backup of a normal original firmware doesn't WORK

backup of a CFW 3.55 with the no check patch WORKS

backup of a original firmware updated from the CFW 3.55 with the no check patch WORKS

and for the semi dual boot you must patch the backup of your CFW 3.55 as in the tut explain!

One last question, in playerkp420's tutorial we need to patch our OFW NOR dump using Rogero's PS3 Nor Dump Patcher but there's no such thing in baileyscream's. What does the NOR Dump patch do exactly, how is it useful and what is the difference between both tutorials?
Thank you very much
