[Q] Downgrade from 4.1.2 - Xoom Q&A, Help & Troubleshooting

Hi,
I have a WIFI Xoom with the latest 4.1.2 update. Unfortunately I am not rooted and it seems that it is not possible to flash a working CWM or to root on 4.1.2
Is there anyway to go back to an earlier android version so that I can then root?
Thanks for any help.

I'm rooted 4.1.2 ?

I got the Xoom after it had the official 4.1.2 update so there is no way to load CWM on it, or at least none of the methods here work.

[Q] Updating official rom from 4.0.4 to 4.1.1 AND root

My tab is originally in 4.0.4 with root.
Then, I flashed the official firmware of 4.1.1 via ODIN to my tab.
I think the official 4.1.1 is not that smooth.
It is safe for me to upgrade with existing root?? Do I need to flash again??
Also, how to root the 4.1.1??
Thanks in advance!

[Q] xperia s & root jb 4.2.1

Hi,
My xperia s got the official Sony update to jb 4.1.2 and (ofcourse) I lost the root.
Is there any way to root my device again?
Bootloader cannot be unlocked!
Tried Bin4ry v30, but no result!
Can I flash from jb 4.1.2 to jb-prerooted? (bootloader cannot be unlocked)
Can I downgrade to ics and than upgrade to jb-prerooted?
Hope somebody has a suggestion/answer.
Thanks

How do you have 4.2.1 when sony never released it
Sorry, must be jb 4.1.2 (6.2.B.0.200)
OK, this is what I did.....
1 Use Flashtool to downgrade to ICS
2 Install RecoverX (FIXED) for ICS
3 Copy JB Prerooted to sd-card (don't unzip!!)
4 Reboot in recovery and install JB-Prerooted
5 Have fun!!
Thanks to everyone who made this possible.......:good:

[Q] how important is it to restore your bootchain after root?

Hey guys, I was wanted to root my gs3 using this guide [GUIDE] Root for Jelly Bean 4.1.1 or 4.1.2 OTA ***UPDATED 5/29*** - xda-developers but for step 6 where you flash the bootchain the only bootchain versions offered are for 4.1.2 are VRBMB1 and VRBMD3. I have Verizon and have baseband version VRBMF1. I know that that step is optional but how important is it? After rooting I am wanting to flash to an aosp 4.2.2 rom or a cyanogenmod 10.1 rom. Will I still be able to do this if I don't restore the bootchain? Also on an unrelated question , i know that the stock android camera doesnt have the option to save pictures to the sd card, Will I be able to do this on a stock android rom? Thank you all for your help

Not very important to flash the bootchain at all. Yes, you can flash whatever rom, kernel, or mod regardless of your bootchain's status.
Also on an unrelated question , i know that the stock android camera doesnt have the option to save pictures to the sd card, Will I be able to do this on a stock android rom? Thank you all for your help

Not sure I understand your question cuz you used the phrase "stock android rom" as a comparison to itself. Do you mean "I know stock android (per a Nexus device) does not have an option to save to external sdcard so does AOSP on the GSIII have this option by default?" If you meant this, I don't believe JB 4.3 roms on our device support it natively. I'm not sure about JB 4.2.2 roms. For example, I've been using Slim Bean beta (AOSP 4.3) since Saturday and there's no setting to save to external sdcard cuz it uses the 4.3 camera. I imagine more of AOSP is like this. More responses will be helpful.
