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?

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?
Hello,
New to this forum and had a question. Seached for about an hour and still could not find the answer.
I have a customer who unknowingly updated her stock gs3 to JB. She very much dislikes and would like to go back to ICS. Is it possible to revert back to ICS after root is accomplished? Any help would be much apprieciated!
I got my new black verizon s3 yesterday and i love it, buttery smooth. I was coming from a HTC Thunderbolt. I had rooted my thunderbolt, however since rooting that phone, i noticed that data connectivity didnt seem to be as stable as the non rooted version of that phone.
Here is my question, do you guys recommend rooting this S3 phone? Has it effected the data connectivity (dropped signals, etc)? Some advice and direction for this new S3 user would be helpful from some of you all who have been S3 users for a while. Thank you!
I would recommend rooting since there is a lot of support for the device. Data should be fine but there have been some problems either user related mistakes or bugs in a ROM. Those problems are fixable. Most of the ROMs are stable even the 4.2 ROMs.
i rooted and i think its worth it. it is easy to do and pretty low risk. I did mainly because i wanted to under clock and get better battery life. I haven't noticed any issues regarding loss of data or anything. i run into some issues at times because i try different kernals and roms that are not 100% in their stable phase. But the act of rooting itself isn't going to cause you any issues.
thanks guys, i am going to root the phone tonight after work. i browsed thru the rooting instructions for the jellybean update software (which i got when i activated my phone). I just didnt want to run into unstable data connections like i had with my thunderbolt.
Can you guys recommend any good 4.1 Roms as well as 4.2 roms? Also what is the difference between android 4.1 & 4.2?
It depends on the ROM as all 4.2 ROMs as of now are AOSP ROMs while the 4.1 ROMs are either TW based or AOSP based.
TW is ok... better then Sense IMO, however I like the stock ASOP feel. I will give a 4.2 rom a try. can you recommend a popular, 100% working 4.2 ROM? I looked in the dev section and there are so many Roms to choose from........ 24 hours of having my S3 and i LOVE it! so buttery smooth!
Blackbean 7 Is the most stable of the bunch as of now.
Ok. If you are going to root and Rom there are some things you need to know.
Your going to want to unlock your boot loader. And make an imei backup incase you lose it during a flash.
Search those up and get them done and your good to go

Do you mean Cm 10.1? Because if you flashed cm10 you're still on 4.1. Cm10 has a stable release while cm10.1 is still on nightlies. I've been running 10.1 nightlies for about a month and have only noticed very minor issues. So minor I can't even remember what they are.
Words fails me. I am so disgusted I have ran out of expletives so I won't bother repeating them here. Seriously...voice dialer is STILL not working! This update was specifically designed to fix this bug and it is still not working. I just can't understand what is so hard about putting back in functionality that was working before in ICS and was necessary.
This is the sort of thing that gets people to switch over irrevocably to apple. This has been going on for like a year now. It is starting to feel like it is being done on purpose for God knows what reason. Does it work for anyone else?

What update? This phone is officially on 4.1.1 . You are not guaranteed anything by running custom software.

Fair enough. Although I never said I was guaranteed anything and apparently we are also not guaranteed to have important functionality (aka voice dialer) to work from one official release to the next. It worked fine when I had ICS it just broke when I was upgraded to JB. I would prefer not to have to root my phone to get it work, but if I waited for the official channels then I will likely have to wait until I get my next phone for a fix.
Both Google and AOKP mentioned that bluetooth issues were fixed with 4.2.2 and I was inquiring whether this worked for others as it did not work for me. Neither 4.1.1, nor 4.1.2 nor 4.2.1 nor 4.2.2 nor any of the other little hacks others have tried have worked and I know others on the official release of 4.2.2 for Nexus had similar problems so I was hoping someone might have run across a solution.
I know I sounded snarky, but I am just really frustrated.
So I do not know if this will help you but I had pacman rom and the dialer wasn't working so I reflashed, no wiping and it fixed it.
Also there is always the option of going back to the stable TW roms. Which is what I did. You can't be mad for things not running smooth when you're running custom roms that make no claims of stability.

Thanks for the info, it was definitely worth a try. Alas the pacman rom did not do the trick. I had the official JB TW update and that is what broke my phone in the first place and I am not really interested in going back to ICS since I got the new phone so I can get Jelly Bean. I have also tried CleamROM and the the latest CM, AOKP and liquidSmooth 4.2.2 along with the just released gapps-jb-130301-signed.zip. No dice.
I'll keep banging away and let everyone know if I find a solution with other ROMs or tweaks.
I am not mad about custom ROMs not working properly I am mad about the official release breaking critical functionality for me.
I tried PK and PA ROMs in addition to aready mentioned. Voice dial does not work in any of them. I also tried Ktoonsez kernel - no dice. I think it's a major JB problem and there won't be any working ROM until Google fixes the issue. I just stopped trying :crying: ...
Hello,
Can any one tell me in a simple pointed way to upgrade my Xperia Ray to Jelly Bean. I am currently on ICS.
I would appreciate a simple point wise response with links to files to be downloaded.
Thanks.

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.
