I have rooted my TF700, but have not unlocked the bootloader yet. I had to downgrade from JB to ICS so i am on the .30 firmware. Should I manually update the firmware to a JB firmware even though I am running ICS? Is there an adavatage, or will the firmware actually install JB back on? Also, when I load a custom ROM, should I also load an updated firmware?

What do you mean.
What would you like to do? Get back on JB (rooted, and locked bootloader) or do you want to flash custom roms, which require an unlocked bootloader?
I guess what I'm asking is, when I run a custom ROM, should I flash an updated firmware?

That depends. I am not that familiar with downgrading, so if you could turn off your tablet.
Then press the power button while holding the volume down button.
Then you should see 'bootloader version' somewhere on the left top corner.
If you could note that down and let me know, that'd help a lot.
It could be possible that your bootloader is still the one from before downgrading. If it is, you can start flashing roms as soon as you have unlocked your bootloader.
If it has downgraded too, you have to
1) Install Voodoo ota rootkeeper & make it protect your root
2) Flash the official latest firmware version
3) open voodoo ota rootkeeper and restore your root.
I think there's a walkthrough for your case somewhere in the general thread. Look for 'walkthrough' there, you should be able to find it.

Depend on the rom build. If the rom build on JB, then yes, you need to flash JB bootloader if you're on ICS. Custom rom only contained rom and kernel.(sometime without the kernel so you need to read the instruction). So if you're on ICS you need to flash JB bootloader (either just flash the bootloader alone or flash the entire firmware which included the boot loader). Then you can flash JB custom rom. If you're talking about the new CleanRom, it's on JB (so you need JB bootloader) and has option to flash stock JB kernel or custom kernel. For me, I always flash the full Asus stock firmware first to make sure I have everything then I flash custom rom. Of course, you could just flash the stand alone JB bootloader then flash Cleanrom.

Hi all,
I have installed various experimental ROMs but found my tablet 'crippled' in many respects. I guess they are still early in their development.
I would like to flash .29 official ROM again and tweak that to my own liking but that will lose root. Since I unlocked the bootloader so I cannot do OTA after downgrade root.
Could anyone help? Preferably give me a fresh copy of WW .29 rooted TWRP recovery backup?
Or does anyone know of a modded .29 Tom out there?
Cheers guys
Just flash the normal ROM, then flash the root zip in the second post of the CWM thread.
I managed to flash stock .29 rom, now I cannot use the wolf's method to downgrade as before, CWM cannot be accessed as before. back to square one.
Try reflashing CWM or TWRP, then flash the root zip. You really shouldn't have to downgrade for anything with an unlocked bootloader.
It seems that the bootloader is just broken. When opened an android lies flat with a body flap open with red lights on.

I am running an old version of black bean with ICS bootloaders and the new roms needs JB bootloaders. What is the easiest way to get that for a noob?
Can I just restore my stock ICS from CWM and uppgrade if it finds a update and then flash a new rom threw CMW?
Thanks!

Restoring your stock ICS will still leave you with CWM recovery. Stock recovery needs to be in place for an update. Probably the easiest is flash stock rom with cwm. Do updates you wish then reflash custom recovery. (CWM or Twrp) Twrp is my choice on this tab.
Note:
Once on JB you can't go back to ICS unless you install nvflash while on ICS.

Where can I get stock ICS that I can flash with CWM that also removes CWM? I don't want to go back to ICS.

If you want to update to JB and not look back consider flashing a stock JB rom. All of the stock updates will also flash stock recovery.
Asus - http://www.asus.com/Tablet/Transformer_Pad/ASUS_Transformer_Pad_TF300T/#download
these you need to unzip once then flash the remaining zip.
http://forum.xda-developers.com/showthread.php?t=1697227
This link provides stock downloads and much more. Skim the op and you can find downloads or links to most things you might need, both now and in the future.
Once you unlocked you could no longer take OTAs.
So I just flash this with CWM and I am done? "ASUS Transformer Pad TF300T Firmware: V10.4.2.18 Only for WW SKU (Android 4.1) - 2012.12.06 update" I live in Sweden, is WW the right version?

Yup, just flash that and youre on jb and latest firmware and on stock recovery, if u want custom recovery you need to use the adb thing.
Can anyone tell me which Custom ROM I can apply to an rooted TF700 running ICS that will upgrade it to Jellybean and retain root?
Thanks!
No answers?

You need to upgrade to stock JB before to get the JB bootloader. And when installing a custom ROM you cannot retain root - either the ROM is pre-rooted, or you have to install a root app via recovery.

No custom rom will upgrade your device to JB, you need to flash Asus stock JB first, or just flash JB boot loader to bring you from ICS to JB. I recommend to flash full Asus JB stock, then after that you can flash custom rom.

Thanks for the replies.
The problem I am having is when I flash the full Asus JB stock, I lose root. How do I upgrade to JB and keep root?

Now solved!
Its good to join a new forum!
Ive decided too take one of tf300s home from work to help feed my root hunger (also running cm10.1 on htc evo 4g lte)
This tablet is currently running 4.0.3
Assuming i will be walking the custom ROM road, should I leave tablet at 4.0.3 or upgrade to JB? I won't have my p c to perform fastboot until next week, this is why i ask.
Thanks in advance :beer:

I would suggest moving up to JB. I've been using CM 10.1 (which is running 4.2.1) on my TF300T and it's been great. The UI and options are better on JB than on ICS, even though ICS was a pretty great step up.

I also just got my tablet now and I'm holding the firmware update while reading, what do you advice? push to OTA or unlock,root,then custom rom? I thought I saw few others having problem with JB is that OTA JB? That's why I'm not pushing any OTA updates for now.
Thanks in advance!

1st solution (That I've made)
Don't update to JB now.
Rooted and unlock in ICS
Backup your root with OTA Rootkeeper
and after JB update by OTA and restore your root with OTA ROOTKEEPER.
2nd Solution:
Or unlock and root your TF and use the NVFLASH tool (with pre-JB bootloader)
3rd solution:
Go on OTA JB Update
Unlock your TF
and use this guide : [ROOT/ROM] Root Stock/Deodex Firmware 10.4.2.20 (US/WW) | Insecure kernel ! when you are on the version of firmware
Go to my index and you will find all the links that you need

Thanks for your help here's what I did:
-Unlocked using APK
-did NVFLASH tool
-flash CWM
-root
-install OTA Rootkeeper
Now I want to install hydro and I know I have to be in JB boot loader the only question for me now to be able to proceed is:
-Install the pending OTA JB update (I dont know if this will proceed installing since it was downloaded while Im stock, I'm afraid it will brick my device since Im now unlocked,nvflash,rooted)
OR
-Just DL latest from ASUS (ASUS Transformer Pad TF300T Firmware: V10.4.2.20 Only for US SKU (Android 4.1)) Can I just install the latest or I need to install pre requisite update first?
THEN
-Install compatible recovery for JB
-Install custom rom

It's really easy now that you're unlocked, rooted and used NVFlash.
I suppose you're still in ICS.
Backup somewhere all of your files (stock rom, nvflash file etc...) use Titanium backup for save & restore your apps later
You can use both process for update your TF
The OTA update, and every time, you are going to have to restore your root.
I'm currently on Android 4.1.2 using Baked 6 and I want to upgrade to Baked 8, or anything on 4.2 for that matter. If I update a ROM, does this also mean it updates my bootloader? If not how to I properly update my bootloader without bricking my tablet? I've been reading around but there's so much data on the forums that I feel like I'm going to accidentally make a mistake

No flashing a custom rom will not upgrade your bootloader, only the stock asus firmwares will do this or a custom made blob file.
There are several methods to upgrade your bootloader to a JB 4.2 bootloader which can be found here or here. I prefer using the fastboot method for upgrading but up to you. Just make sure that once you've upgraded your bootloader to a 4.2 bootloader that you flash a -4.2 version of twrp or you will brick. I would suggest upgrading to JB 4.2 - 10.6.1.15.3 & twrp 2.5.0.0-4.2 as I find this more stable than 10.6.1.8 & twrp 2.4.4.0-4.2
If using the fastboot method and you need any help with any step just let me know.
