Being new to the forums it would appear I can not post this in the relevent thread to tell the Developer perhaps another forum member or a Mod could link to this article later.

People flashing the latest nightlies since 2013/07/06 have been unable to install the latest CM10.1 nightlies if they're using the CWM 6.0.2.5 official clockwork mod recovery bootloader.
It would seem the newer recovery flash only supports the TWRP.blob and not the official clockwork recovery mod.
This is not a Bootloader issue caused by having a bootloader that only supports 4.1 and not 4.2
Because the last build before this happened was CM10.1 20130706 (4.2.2) which was working fine when you clicked the CM10.1 update button.
So in order to re-flash the latest nightlies it would seem I have to go and find another PC, dig out the USB cable's put the device back into fastboot and flash the TWRP.blob which I havent had the time to do and fail to see why that's needed if the Official CWM Bootloader was doing the Job previously.
Anyone know why the TWRP.blob seems to have taken precidence over the CWM? Or why the latest nightlies are incompatible with the CWM 6.0.2.5 bootloader which until the 20130707 Nightly update had been working and upgrading the build perfectly???

Howdy folks, it appears that I've run into a bit of a hurdle playing with my transformer.
-----------------------------------------
Problem:
Stuck Boot (static "ASUS" logo, with nvidia logo in bottom right and "unlocked" in top left)
-(rebooting into bootloader and recovery is possible)
-----------------------------------------
Background Steps:
1. device got the 4.2.2 OTA from ASUS and is running the 10.6 bootloader
2.performed 4.2 unlock as per ASUS instructions
3.loaded TWRP 2.5 (4.2 version)
4.did a full wipe within TWRP (except SD)
5.installed stable release 10.0.0 =
6. wiped cache and dalvik
7. rebooted
------------------------------------------
I figured this was a problem with the kernel (similar symptoms before on previous devices) so i went into fastboot and loaded the boot.blob from the cm zip. - It had no effect!
I then wiped and tried again with 10.1 (nightly), again updating kernel - It had no effect!
Getting nervous, i flashed a rom based on stock 4.2 (kernel flash was required) -It's working but not what I want to end up with.
-Can you folks help me out?
Any help is appreciated
As far as I know the this [OFFICIAL][4.2.2][TF300T][NIGHTLIES] CyanogenMod 10.1 for TF300T does not work with the 4.2 bootloaders, even though it's 4.2.2 it needs a 4.1 bootloader like 10.4.2.20.
There is an experimental build for the 4.2 bootloaders here [ROM][4.2.2][CyanogenMod 10.1 Unofficial][TF300T(G) with BL 4.2][2013-05-09], if your using twrp 2.5.0.0-4.2 you should have JB 10.6.1.15.3 bootloader as twrp 2.5.0.0-4.2 on JB 10.6.1.8 has a split-screen issue.
As far as I know, the official CM10 and CM10.1 (including nightlies) are still not compatible with the ASUS new 4.2 Boot loader. You have to wait a little while for the official CM10.1 maintainer to catch up.
However, there is an unofficial CM10.1 that can work with your current 4.2 bootloader, look here: http://forum.xda-developers.com/showthread.php?t=2252990
would you recommend downgrading to 4.1 to use the stable release, or should is it safer to just stay with what i got til they decide to make an official cm release that'll work with it?

It is safer to stay. Messing with recovery, fastboot and bootloaders is risky business. Although, it may work, there is also a chance you might brick your tablet when done incorrectly. Not that I doubt your abilities. It's just that we are seeing an alarming rate of bricked TF300T being reported in the forum. Better wait for a much safer version of TWRP recovery.
EDIT: However, if you have NVFlash backup of your tablet, downgrading and bricking won't be much of a problem.
Roger, i'll stay with 4.2, maybe i'll try that experimental 4.2 one.
My device:
- TF300
- Android 4.2.2. / CM10.1 (10.1-20130621-nightly-tf300t)
- WW_epad-10.4.2.9-20120809 (= 4.1 bootloader version)
- TWRP 2.6 recovery (for bootloader v4.1)
My aim is to update to CM10.2, therefore I need a bootloader version 4.2. I downloaded the latest firmware from the asus-website (TF300T-WW_epad-10_6_1_27_5-UpdateLauncher.zip) and put it on /sdcard.
But I'm in doubt:
- Is the asus firmwire described above the best way to upgrade my bootloader? And can I use TWRP to install this zip?
- If so, do I need to change the TWRP version to 2.6 ready for -4.2 (teamw.in/project/twrp2/97) not at all, before or after I installed the new bootloader?
I know bootloader/recovery issues can easily brick a TF300, so to be sure I ask. Thanks in advance!

I flashed the blob via fastboot. Then flashed recovery via fast boot. Then cm10.2 from recovery. I was on old June build of 10.1 and 4.1 bootloader same as you. Be safe fastboot flash follow guide in q and a section

Same question, but not exactly answered: can you do this without a cable connection with your pc?

Honestly, I'd rather be safe than sorry when upgrading bootloaders. So I would always suggest using the cable connection because it is less likely to fail. You probably could get away without using it to flash stock, but you wouldn't be able to flash TWRP without fastboot, and then couldn't flash a custom ROM. But everything feels safer once you have Nvflash backups.

I was in the same situation as you not so long ago. Was on 4.1.1 with TWRP 2.6.3.0 JB installed. Asked myself these questions repeatedly. I updated via fastboot to the staging partition using the blob within the latested ASUS firmware zip file. The blob file contains, bootloader, recovery, system and boot. This means your are essentially returning to stock everything upon flashing. This was a huge sigh of relief as I didn't want to brick my device because of the same concerns you have. So I flashed via fastboot to 10.6.2.10 then flashed to TWRP 2.5.0 4.2 as 2.6.3.0 didn't work for me for some reason. I heard a number of people say that 2.6.3.0 4.2 is buggy and suggested to stay with 2.5.0 in which I would recommend from experience. Then flash your custom firmware.
Pretty lost by now. I am still (sick of it) on an unlocked Asus stock 4.2.1 with TWRP 2.5. My intention is to change the ROM but was considering CM 11 which I understand does require TWRP 2.6.X at least. I was hoping for a fix for installing navflash on post JB but I believe does not possible so anything that means touching the bootloader makes me very concern.
I was wondering:
- Can I flash TWRP 2.6 (4.2 img file i beleive) directly from my already installes TWRP 2.5 bootloader and then install CM 11? or do I need fastboot process again?
- Is CM 11 worth on the TF300? I just need some stability and reasonable speed after having so many problems with the stock rom.
Thanks.

Yes, CM11 requires TWRP 2.6.3.1.
You can install NvFlash on a JellyBean Bootloader, link and guide is in my signature.
If you bootloader is above 10.6.1.8, you can just flash the TWRP 2.6.3.1 and then reboot and then flash CM11 + gapps.
I think it is super smooth with the OC Kernel.
I'm not being able to flash recent roms. I keep getting error status 7. For JB 4.2 and later, I can't flash them. I can flash rom 4.1.2 and earlier.
I'm on 3.18 firmware (latest i think). unlocked and rooted. BUT I have S-ON, is that the problem? If I S-Off. will I be able to flash recent roms? I want kitkat on my phone Sorry im noob
What recovery version are you using?
Sent from my Evita
2.5.0.0 i think, ye. that's it. but I tried with both CWM and TWRP, non work. I suppose S-off is the problem right?
Your recovery is the problem. If you want to flash KitKat ROMs you need the modified TWRP 2.6.3.0 by jrior001, you'll find that in our Original Android Development section. Any other ROM you want the official TWRP 2.6 which you'll find here:

I am able to flash my tablet back to stock and root as well as install custom recovery using Easy Flash, but can't flash KK or a newer version of TWRP. I have run KK before (4.3 I think). Keep getting message that I'm unable to open the zip file.

Well, I was, but with a little help I have now successfully updated twrp to current version. Thanks SidneyK.
However, I am still unable to flash KK 4.4.4-033. I have also tried flashing older versions of KK (i.e., 4.3) with same result. Not sure what to do from here.
Update: Successfully installed KK 4.4.4 using the side loader feature of TWRP. Everything is now right with the world
