[Q] Downgrade AOSP JB To Official ICS Asus .26 or .30 - Asus Transformer TF700

Hi all
I would like to install the new official update for jelly bean
Actually I'm on Baked Black Bean (AOSP) Jelly Bean
I think I cannot install directly the update from a custom rom
So, is it possible to downgrade from jelly bean AOSP to ICS asus .30 or .26 and after apply update for official jelly bean ?
Thanks for your answers

No, you cannot flash stock JB over a custom ROM because it is only an update package, as has been referenced on multiple threads by now. Please refrain from starting a new thread to get answers that have been given multiple times already, since that only keeps us busy with reiterating ourselves.

If you get stuck while having read and reread these threads, making sure you get the point, do chime in and we'll help you out.
One word of advice, though: stay away from .30 UNLESS you already have NvFlash installed -- in that case, it seems only nuclear disaster could wreck your 700. In essence, the same would go for stock JB -- as we don't know what the side effects are as of yet -- but, hey, you seem bent on finding out. If you do, tell us, OK?

[Q] Some very basic questions about new ROM

Hi! I have a US Cellular Samsung Galaxy S (SCH-I500). The current OS is android 2.3.5. I know that this will never get ICS or Jelly Bean, so I am thinking about using this as my first foray into Rooting/Modding. I would like to see Jelly Bean on this phone, but will settle for ICS.
I have spent the day reading post after post. I know more now than I did when I started, but still not sure how to proceed. I am really looking to upgrade the UI, but want stability and full functionality.
1. When done, do I still use the Google Play store?
2. Will the camera, text, phone, etc. all work?
I am looking for a Jelly Bean OS (ROM?). I have downloaded AOKP fancinatemtd jb milestone 1. Will this work on my phone, or is there a better fix?
Looking at this post: http://forum.xda-developers.com/showthread.php?t=1238070
I am not sure if this is the right set of instructions? If they are, at what point do I use the AOKP?
As you can tell, I am very confused and would appreciate some step by step direction. Thanks.

[Q] KT747 Kernel Question

Hi everyone,
Quick question. I've been searching the forums and dev section for a while now, and couldn't find a concrete answer, so I made an account to simply ask. If I am on the Verizon OTA JB update, 4.1.1, rooted with an unlocked bootloader, can I flash the KT747 Kernel without any adverse impacts? I am looking to keep my rom stock for usability (I used to flash all the time on my Droid X and stability issues were problems), but would like to increase performance via a modded kernel. I am just wanting to make sure, since the dev section says I need either JB AOSP or TW. I assume my stock OTA JB is TW?
Sorry for any naive questions. Thanks in advance!

Yes you can with custom recovery.
Ya you want the touchwiz kernel, here is the link http://www.mediafire.com/?ixn5n9xjnwbve8r
Thanks guys!
I flashed it and everything seems to be running perfectly fine. I will give it some time until I form an opinion, but I hope I can get the results that many others are reporting.

[Q] Kernels for Jelly Bean

Does siyah, yuma, any of those work on JB? If so, can someone point me to where they are so I can download? If you would be so kind.
And if they are not workable/not tested, I don't mind testing them out.
Or, are modems the best choice of action right now?
If so, I can be satisfied with what bscallions has in his flashable modem thread.
And yes, I've searched but majority of those threads are old.
Yes, some of those kernels work on JB - they do not however work on the Infuse.

Custom ROM, Official JB ROM is not released for 2011 Xperia phones. Moreover, ICS is damn too slow and hence wanted to try out Super Jelly Bean. Don't know what should be the exact sequence of events.
Appreciate any help!
No ROMs I could update

And if you all believe I did not search the forum, I downloaded almost 5-6 custom ROMs, kernels and flashed them but the phone doesn't just boot up.
ICS 4.0.4 did not allow for rooting hence went for 4.0.3 and rooted. Since, last 2 days, I flashed my ray more than 10 time with no success.
No Jelly Bean ROM I could find which would make it workable. Hence, settling for 4.0.3
Thanks.

Hello. How come you didn't get an answer yet? To flash any custom rom all you have to do is to unlock bootloader. Just google the phase "Unlocking the boot loader" and the first link will lead you to the official website with all the instructions (I can't post links since I'm new here). The only problem is that your warranty will be void (if it is a problem). Some roms can be flashed without unlocking, but Super Jelly Bean is not one of them (as far as I know).

Actually before I used SJB 7 for my ROM on my Ray.. I used ICS 4.0.4 Stock ROM from SONY, but ICS stock ROM too laggy.. So I decide to change to custom ROM and I use SJB with fusion kernel 5.4 and it works fine... ICS 4.0.4 can root.. just follow instruction on http://forum.xda-developers.com/showthread.php?t=2135918

Hi, maybe am late or maybe not, anyway
I recommend using test point method to unlock your bootloader so you don't lose your DRM data. Proceed with caution do not attempt this if you don't know what you are doing,** I take NO responsibility if something happen to your phone, you are doing this at your own risk.**
here is the links: www[DOT]androidflip[DOT]com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
sorry am a new user i can't post links replace [DOT] by .
And also i recommend using Super Jelly Bean 8.0 as its a great ROM very smooth and with nearly no issue.
hit thanks button if this help.

Thanks everyone. With so many help options provided by you fellas, I could flash custom roms. After trying virtually everything, I've settled with SJB 8.
Thanks,

Tried various ROMs and I must say this forum is very helpful.
Not sure how do I close the thread, incase there is any need for it.

[Xoom2/XYBoard] Downgrade JB to ICS?

So I updated my MZ607 to JB using the guide here:
http://forum.xda-developers.com/showthread.php?t=2591388
To be honest JB runs horribly on it; it's slow, laggy, unresponsive to touch input and I wish I hadn't bothered. In short I wish I could go back to ICS, which sort of worked.
Some people claim to have done it (but aren't responding) and some people claim it is impossible. Has anyone genuinely had any success downgrading from JB to ICS on the MZ607?
