[Q] JB Update/Upgrade question

Can someone tell me what's the difference between the OTA Update to JB vs. flashing the .zip from the firmware dowload section on the Asus site? The OTA update is a patch I assume, and the .zip is a full ROM image?
Is there an advantage to using one over the other?
Thanks

I'm also curious as to how this is. I downloaded the JB update zip from asus website. Like before I unzipped it and placed in /sdcard . I was notified of an update, I clicked it and it rebooted into my custom recovery instead of flashing it like it did from .26 to .30 . Did I flash CWM (NONTOUCH JB compatible version) just a little to early?

Upgrade to JB bl (noob)

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.

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.

Unrooted TF700

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?

[Q] Firmware

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.

[Q] Returning to Stock ROM

So, I kind of know about this stuff, but I have my doubts. I have TWRP with CROMi-Xenogenesis 4.6.4 but I need to return to the Stock ROM, or at least the latest update from Asus. If I just flash it through TWRP will I be fine? Thanks!
