Why isn't it possible to flash ics bootloader after having installed jb bootloader? I have done the opposite on other devices

Because Asus has given us a new bootloader which asks for a special signiture in the rom you are flashing. ICS don´t have them, so it is not possible.

Although I thank you for the answer, my question wasn't why we can't flash ICS ROMS, my question is why we can't flash ICS bootloaders in order to be able to flash ICS ROMS.

becouse recovery too has this signature - basically the difference between an ics custom recovery and a jb custom recovery is that they copied the jb kernel to the latter, or it wont work too.
its a new security feature that google added to jb but asus is using it in a weird way, once you do a jb upgrade you wont be able to run any kernel without this feature, which is not supported by ics.
there must be a way ... i want to flash CM9
I'm not sure why would you want an ICS ROM in Jelly Bean era.
Check out this thread, it's the best JB ROM I've tried.

you can run Jelly Bean Roms which are Cyanogenmodbased on ICS bootloader - any questions left?
Can't you flash CM10 on JB bootloader?

hey guys i wanted to try the stock jb from asus but im on running the great hydro ATM and i wanted to know the eaisest way to update it, could i just download the update file from asus and extrct it once and put it on my sd card and let the tablet do the hard work, and use voodoo to keep root???
Hydro for JB is rooted - no need for the stock JB to be rooted, just install JB.hydro

I was also a little confused at first.
But I just started with downloading the update from asus, unzipped once - placed that fil in root on the internal sdcard.... and when the notification about update came, I let that run to the tf was on JB.
The fastboot and flashed TWRP - and from the TWRP I did all the clear cashes etc and installed JB-hydro... now on 1.3.2 - just running perfect

Hi guys i've been looking through the forums and i have noticed that the tf700 users can flash our roms! I was wondering did anyone try flashing one of their roms with our device?
Sent from my ASUS Transformer Pad TF300T using XDA Premium HD app
Just checked over there we have more updated roms anyway there development seems slow that why they have to port ours lol.
Sent from my SGH-I717 using xda app-developers app
I agree but in the long run development for their device should pick up and surpass the development we have for ours. So if we find a way to use there roms it will lengthen the amount of content for our tablet.
BUMP! I'd like to get an answer to this as well. It seems that everything is the same other then an LED. Has any tried flashing one of their Roms?
I flashed the TF700 Stock Rom Was trying to get back to ICS. Stock flashed and was running. But then you have the tf700 bootloader
So you can flash them.

Hum... does this means that we will have 1.5Ghz kernel on our TF300T ?
Excuse my noob-ness.
I'm under the impression that, in order to upgrade to a cm10.1 Nightly rom, I need to change my recovery? But in doing that, there's a somewhat lengthy process... can someone show me how flash a jb rom without a potential bricking?
Sent from my Transformer Pad TF300T using XDA Premium HD app
Pretty sure that you are gonna want to upgrade to a JB bootloader first. Flashing a JB ROM on a ICS bootloader will probably result in a bricked tablet. Just changing the recovery won't work either.
Be be careful with the bootloader you flash too. There aren't many ROMS that run on the newest 4.2 yet. Pretty sure you're gonna need to flash 4.1. I don't run CM10 so you will want to verify the information but I'm pretty sure I'm correct.
A good place to get good info on what is needed to run CM10 is in the CM10 nightlies thread.

Hi, a'm using energy rom on my tf300t, and very like it. Now, i want to upgrade to a new one, 4.2.1 from 4.1.1. I can flash it, but it never boots, first i get dual screen, then the installation stops. Aroma writes, my bootloader is ok., ican flash the rom. I had cm 10.1 rom before too without any problem. Please, help me.
Thanks

if im not mistaken, first you should update official asus 4.2.1 to get newer bootloader before flashing 4.2. based energyROM.
i belive now you have 4.1.1 bootloader, right?
edit: nevermind, missed the cm10.1 -part..

Check the md5sum of the ROM...something may be corrupt
you must first update to 4.2.1 bootloader before you can flash roms based on the 4.2.1 bootloader, silly.

No it runs on the 4.1.1 boot loader. Just cuz its android 4.2.2 does NOT mean that its runs on Asus 4.2.1.

I think you can upgrade and downgrade Asus stock ROM just by placing the firmware on an sdcard. No need to unlock in this case.
You probably need to unpack the downloaded ZIP once.
There are more details somewhere, use search!
