[Q] Signature verification failed on official JB update? - Galaxy S III Q&A, Help & Troubleshooting

Hey guys, newb here.
I'm running a rooted Galaxy S3 International version I9300 on ICS 4.0.4
I'm using the official stock ROM, and I've flashed no mods/scripts/themes.
So basically the only modification I did to my device was rooting it.
I also see that you'll be needing this: (*#1234# dial)
AP:I9300XXBLH1
CP: I9300XXLH1
CSC: I9300OXFBLH1
So I got the official JB software update for my phone this morning, downloaded it and tried to install. However, the device aborted the installation because it failed to verify the signature. I've re-downloaded the official update 3 times, and the same thing happened 3 times. What do I do?
As you may have noticed, I'm a complete noob at android terminology, so if theres any way you can make your answer simpler, please do

If you are rooted then you will have troubles installing OTA updates..
If you are flashing the update using CWM recovery it will give you this error..to install OTA use stock recovery..

What you need to do is to first reboot into recovery, format /system partition, THEN flash the stock rom by Odin...... hope I helped

This happened to me
I had the same problem when I first unrooted. Go into stock recovery after flashing the official ROM and do a factory reset.

Trying to flash OTA jelly bean but getting errors

Hi all,
I have a rooted (through Odin desktop version) Galaxy S3 I9300 with the following:
AP: I9300XXBLH1
CP: I9300CELH1
CSC: I9300PHNBLH1
I have been trying to flash the Jellybean OTA firmware that was posted yesterday on:
http://forum.xda-developers.com/showthread.php?t=1867672
However when I try to flash with CWM it breaks off.
When I try this with Odin Mobile Pro I get:
"The kernel image on your device does not match the signature check in OTA ZIP. Disable the check (may prevent the device from booting)?"
I guess I have to update the kernel image somehow in order to install this OTA as was also mentioned in the thread with the Jellybean firmware:
http://samsung-updates.com/fw/Samsung-Updates.com-GT-I9300_BTU_1_20120806161432_al03it6wa2.zip
However it's impossible to download this file, have tried with 4 different browsers on 2 desktops and 2 browsers on my phone but no luck (I get dummy zip file, referred back to the same page or html file download).
Any tips on how to update the base/kernel rom so I can safely install the Jellybean OTA?
Thanks,
Vincent

If you are already on a ICS rom then you can flash LG8 without wiping, if your on a JB rom then you will need to wipe or the ICS rom won't boot!

Hi,
I just tried to flash XXBLG8 with CWM (source: http://forum.xda-developers.com/showthread.php?t=1799267) but when doing *#1234# I get exactly the same versions as before:

Any ideas what I'm doing wrong?

That link is only the kernel and modem not the full rom

Correct, but I tried to install the full rom directly and it failed (see my first post of the thread), so I figured I had to upgrade the kernel and modem first..
I have the feeling I am missing an obvious step here, :silly:

[Q] Android newbie. Need a simple help.

Okay first of all as the title says, I'm new to the android OS. I successfully rooted my I9300 4.0.4 by reading and using the toolkit 5.0. So now I'm rooted with stock ICS. My question is, will I still be able to update into jelly bean build LJ4 via OTA or Kies? Will someone please enlighten me on this one. Thanks in advance.
Friend i think when we root ota update is blocked.but yes you can update it via Samsung kies.but you will loose root .
Also you can get yourlatest firmware (jelly bean or whatever) from samfirmware and flash it.

OTA: no
Kies: yes but you will loose root, hence re-root
Sammobile: download and flash via Odin, you will loose root, hence re-root
Sammobile: download and flash via Mobile Odin, you can keep root (pro version)
Hey thanks for the quick response for the both of you. Will try on kies first then sammobile if I'm not succesful. Will be any complications regarding your suggestions? Are those firmware from sammobile official?

yes, sammobile has official versions as well as leaks (marked with a orange sign), hence make sure you get the correct version.
There is also a neat guide to flash a rom in the stickies incl. a video.
Also you can try an option called "ota survival" in super user app.
But it do not works for all devices.

[Q] Rooting S2 I9100G JB

Hi,
I have an I9100G running stock JB (DDLS3). Is there a way I can root it without flashing a custom ROM? I tried using jiangyi's and ryuinferno's methods, but both return a signature verification failure error in recovery mode.
Has anyone rooted this firmware yet?
Yes. Heaps. With Ryuinferno's Su+Bb installer method on stock XXLSR, it works.

I tried doing that. It says signature verification failure when I select the SU-BB zip file in recovery mode. Looks like they changed something in the Indian firmware.
Or you can flash stock XXLSR and do the Su+Bb zip flash method instead? Last I checked the Indian release are missing a few features. Just saying...

[Q] How to unroot galaxy mega 5.8??

So i rooted the device using odin 5.0.7 and saw that i cannot update my O.S
Can anybody give me a step by step instruction on how to unroot my device or if there is any way to upgrade my rotted device??
P.S-I am a newbie and i know very little about such things
If you have superuser by chainfire then you can unroot using the app itself. Otherwise download and flash via odin any stock firmware to unroot. Better still flash the latest stock instead of ota updating.

If you want root you are going to have to flash the new Roms as they are released and not try OTA anyway. If you want stock, that's fine, but you can't do much around here with a stock Rom.
