Question Any warnings/heads up to offer me? Leaping over many versions...

My TF300T still has the old stock firmware from October 2012 (4.1).
It is unlocked and has TWRP from february 2013.

Now I will be jumping to a current custom firmware (Crombi-kk 4.4).

If I understand correctly, I have to flash the latest STOCK firmware (V10.6.1.27.5 android 4.2) and install the new CWM/TWRP before I can flash a custom firmware.

My main worry is flashing the newest stock rom on my already TWRP/rooted/unlocked TF300T. Will that cause a problem or will the stock firmware wipe everything clean (except for the unlock)?

Also, the unlock utility on Asus's website is made for 4.2 only. When I unlocked my TF300T, it was 4.1. What will happen when I flash the stock 4.2? Will my 4.1 unlock cause problems or will it be wiped, or will it still be effective?

Thanks for your offer. I actually got the green light on the CM 4.4.x Q&A thread.

I read that flashing the CWM for 4.1 would brick your tablet if you had 4.2 installed, so I was worried that flashing 4.2 on top of an existing 4.1 CWM would brick it as well. It turns out it simply removes the CWM entirely. Good times.

Basically what I ended up doing was:

1 - Transfer the latest official TF300T firmware (zip file) onto an SD card.
2 - Start my TF300T with my old (4.1) CWM recovery and select to flash my android with the zip file on the SD card.
3 - The TF300T bootloader stayed unlocked, but the old CWM was gone.
4 - Using ADB: Upload & flash the new CWM Philz Touch
5 - Install/flash the desired custom rom (from within CWM using SD card)
6 - Restore to factory default (from within CWM)

Now I even installed Grimlock's kernel to allow overclocking.
My TF300T has a new life. It is now very much acceptable in terms of speed.
