-Google

@iGoogleNexus i just updated ice cream sandwich. Not via the guy called beezys btw
however i want to downgrade! As i searched trough internet i couldnt find any answers besides your advice (which did not work for me). If you could help me i will be really appreciated. Please help me and my hopeless situation

Unroot your phone, then you'll be able to flash anything you want, even 2.3.3 no matter what rom you're currently using.
Good luck!

Great! Thank you so much however I don't know how to flash it :/ (n00b)! It would be perfect I'd you could explain it to me too! Thank much you sooooo much again!!!

I'm going to follow this thread closely.
Noob here too.
I have the bone stock NS, I9020T (not rooted) and got the OTA update of ICS 4.0.3. Like the OS but there are too many apps that are either buggy or simply don't work on ICS.
I downloaded the "Android 2.3.6/GRK39F/XXKF1 Radio/KA3 Bootloader" rom from here on XDA, renamed it to "update.zip" and copied it to the phone. When into the bootloader, selected Recovery and then selected "apply update from /sdcard" and selected "update.zip"
When trying to install the "old" rom, I get this error:
--Install /sdcard ...
Finding update package...
Opening update package...
Verifying update package...
Installing update...
assert failed: !less_than_int(1316544229. getprop("ro.build.date.utc"))
E:Error in /tmp/sideload/package.zip
(Status 7)
Installation aborted.
I have looked all over the XDA site, Android Central and searched Google in general and can't find some simple step-by-step instructions to go back to Gingerbread.
I am SO looking forward to someone to tell me (us) what we're doing wrong and what I (we) need to do to get back to Gingerbread.
Thanks in advance from a Moderator from another (motorcycle) message board.
UPDATE: Installed fastboot and my bootloader is unlocked. Tried again to go back to GB using the steps above and I still get the same error.

good topic ... bump to top for expert advice

As a matter of fact it is not that easy my friend i also tried that method however it did not worked for me too, it gave me the same error. So as rafael said we gotta unroot our phones and we can flash it from there (but how? ) it would ve awesome if someone could help
Thanks

BRICKED!!!
OK i think i bricked my phone after unrooting it i finally got back to gingerbread but a gingerbread that is only capable of mounting and unmounting the storage after unrooting suprisingly clockworkmod recovery was gone! most of the tasks end unexpectedly such as acore, setupwizard and calendar. in android system recovery i have only 4 options: reboot the system, apply update from /sdcard and wipe various data. Besides my mac doesnt see the nexus s via ADB. I am wrecked what should i do?? Any pro tips??

First off, I want to reassure you that your phone is not "bricked". If it was bricked, it would be completely unusable, wouldn't turn on, show anything on the screen etc.
It sounds like you didn't wipe your data before installing the new ROM. This can lead to force closes and issues like what you are experiencing - I have done the same before.
It will be possible to recover your phone. You say in the Android recovery you have access to "Apply Update from SD Card" - simply use this option to flash another ROM, but this time make sure that you wipe the data beforehand. Bare in mind this will remove all personal data from your phone such as apps, contacts etc. However, this should be synced with your Google account and will re-download to your new ROM.
It would be good for another forum member to confirm this before you do anything - I don't have a Nexus S yet (getting it tomorrow ) but I am a developer for other Android handsets.

OK problem solved. After i unrooted somehow magically gingerbread 2.3.6 installed itself (or i did somehow i dont know) after the gingerbread installation i installed the clockwork mod recovery. I found the correct software (Ice Cream Sandwich for Nexus S) and installed it and the system is running silk smooth for now
Thank you everybody who helped me working this out really appriciate it

Here is what I did...

I have the same problem, how to downgrade from ICS to GINGERBREAD using only non rooted system and OTA update?
I have ICS 4.0.3 if I would like to downgrade Nexus S to 2.3.6 how to i can without root ?
The message is the same
...
assert failed: !less_than_int(1316544229. getprop("ro.build.date.utc"))
E:Error in /tmp/sideload/package.zip
...
I think that is impossible (without rooting the phone) because probably this assertion
1316544229 < getprop("ro.build.date.utc")
is every time false with condition !(date build of gingerbrade < date build of ICS)

[Q] Troubles after updating firmware

Hi all,
I decided to install the InsertCoin 4.4.0 Custom ROM, apparently I needed to update my firmware with a link provided. While in the Revolutionary Bootloader I instantly got a message asking wether I wanted to update (I assumed that was the firmware). The update apparently went OK and I got a message 'Press <POWER> to reboot.
However, when pressing the Power button the device reboots, but after the Quietly Brilliant screen the device constantly reboots again, resulting in a loop. When going in to the Revolutionary Bootloader I get the same update message.
So, updates seem to go okay, but I can't get my device started again. Hopefully this is fixable, but unfortunately I'm still not that familiar with software like this.
Thanks in advance!

I am having the same issue after updating firmware..help guys!

By removing the SD Card, Booting into Recovery I can get in the recovery menu. Then by putting the SD card back in and mounting it I can restore the device using the backup I created just before I updated. But that apparently doesn't solve the problem, it still crashes after the Quietly Brilliant screen.

download new 4.4.0 and flash

Apparently I need to install the firmware update first. I'm not sure if installing 4.4.0 is a smart idea now that it seems the firmware update failed.

Ok i found the fix..just remove the firmware file from the SD card by deleting and install the new ROM thru recovery...but first do a super wipe..and then install the new ICS rom..that will fix everything. Given you didnt restore ur device..do this after updating the firmware..

Thanks. I managed to fix it and have installed IC 4.4.0. Didn't install the firmware update though, but it seems to work fine. Apart from the fact that all data on my SD card is not recognized. But that's not really related to this topic anymore.

Download the 3.24 firmware, place it on the root of your SD card, boot into bootloader and update. After update has finished, press power to reboot, do a battery pull, put the SD card into your computer and delete the PMG15 zip, put the SD card back in your phone, boot into bootloader, select recovery, flash ROM, enjoy.

Thanks, but I don't have a PMG15 file on the SD card after installing the Firmware. I ran Super Wipe, rebooted in Bootloader, let the installer install the PG58IMG file (after checking the MD5 sums). Basically did exactly as you said, but I can't find a PMG15 zipfile to delete.
I don't even care anymore if I manage to get IC 4.4.0 installed (also tried, ARHD 6.1.0, doesn't work either), I just want my phone to work again.
EDIT: Regarding the firmware, I'm not sure what CID I have, I haven't installed SuperCID yet, and I can't install it now because I can't boot up the device, which is necessary to get SuperCID.

It's not PMG15, its PG58IMG....sorry I couldn't remember the exact name....but you should get what I'm saying right?
Sent from my HTC Sensation 4G using XDA App

Ah, yes. Well I did figure that out earlier, because if I keep the file it simply keeps updating in Bootloader. But it still doesn't get past the HTC splash screen when I try to start it up after installing a custom ROM. InsertCoin 4.4.0 shuts down right after 'Quietly Brilliant', ARHD 6.1.0 keeps rebooting at the plain HTC screen.
Thanks for the help so far, still giving me headaches though
EDIT: ARHD 6.1.0 now manages to get past the Quietly Brilliant screen and reboots as soon as the Beats logo flies in. It's progress, but it's still constantly crashing.

Unable to get 4.0.4 OTA Update

I have a Telus Nexus S running the following;
Baseband Version: i9020AUCKF1
Kernel Version: 2.6.35.7-gf5f63ef [email protected]#1
Build Number: GRK39F
I tried to do the OTA update, and it says there are no updates.
I followed this to try to force it to find an update;
Settings --> Applications -> ALL -> Google services Framework --> clear data
2) and do the check in code in the dialer - dial (no spaces) * # * # 2 4 3 2 5 4 6 # * # *
Doesn't seem to work.
Is there any way to install the update to 4.0.4 by flashing it on the phone?

if you know how to use fastboot then you can use these images corresponding to your phone model http://code.google.com/android/nexus/images.html#soju
and here is a guide to use fastboot to flash these images http://forum.xda-developers.com/showthread.php?t=1572307
or
you could use this http://forum.xda-developers.com/showpost.php?p=24379505&postcount=87

So I got it updated, following the instructions I found on another site! The package contained an update.zip which was the ICS build IMM76D
This package is for the AT&T/Telus/Roger/Fido/Bell versions of the Samsung (Google) Nexus S running Android 2.3.6 Gingerbread build GRK39F. It will update to Android 4.0.4 build IMM76D. If you have any other version of the phone or Android - IT WILL NOT WORK! Please stop now.
Also, proceed at your own risk.
1. Place the update.zip in the root directory of your MicroSD card.
2. With your Nexus S off press and hold the volume up button and power button until your phone turns on. It will enter a recovery screen.
3. Scroll down using the volume down button and select Recovery by pressing the power button.
4. In a couple of seconds you will see a yellow triangle on your screen, now press the power + volume up button to get to the file selection screen.
5. Choose to install update from SD card using the volume up/down to move the selection and press power to select.
6. It will take about 5 minutes to patch required files and reboot. Upon reboot, it will patch more files during first launch of Android 4.0.4.
It's all working, nice and smooth, love it!

I'm helping a friend with her phone and its not working and this thread helps a lot, but stuck on one part. She is on Android Version 2.3.4, Kernel Version 2.6.35.7-ge382d80. How do I get her phone updated to version 2.3.6 so i can then perform the 4.0.4 update for her?

Read the comments section, he talks about first upgrading to 2.3.6, then flashing the ICS update. Really straight forward, just make sure your phone is one of the above.

The above should work for AT&T/Telus/Roger/Fido/Bell Nexus S phones which are on 2.3.6 or follow the instructions to get to 2.3.6, then update to ICS 4.0.4.

I just tried to on my friends phone but it failed on the 2.4.6 update (the 17mb one).
Here is the output/error
-- Install /sdcard ...

Have you tried to OTA update the phone to 2.3.6? Also the phone is I9020A?

The only OTA is the 4.0.4 and it fails every time it tries to update.
The phone is GT-I9020T.

Yeah those instructions to update it will work for i9020A only

Download this ~17mb update;
http://android.clients.google.com/p...c0.signed-soju-GRK39F-from-GRJ22.7d114042.zip
Run that the same way you did earlier, it's the update for:
Model: Nexus i9020t/i9023
GRJ22 (2.3.4) TO GRK39F (2.3.6)
After you're done, then try the OTA once it's confirmed updated to 2.3.6.

She had to leave, but will be trying it tomorrow. Thanks for the help! Where are you finding these links? Ill be playing with my samsung galaxy s2 soon.

Hey there.
I tired that last package and it still failed. It gets farther, but fails after "verifying current system..."
I'm attaching a picture of it.

Need Help With Tablet Update

hi there everyone,short time reader,first post after searching and not finding the help i'm looking for.need a little help with a xyboard 8.2.i did the dan rosenberg root method and deleted a couple of things that i never used.i got the one item back in,but now i can't do the update that verizon pushed to the tablet because of a evernote(one item i deleted) problem.i have re-installed it and it will update on its own,but i can still un-install it since it doesn't see it as a pre-installed app.had i know this would be a problem,i would have never rooted the tablet and just left it alone.it work's out perfectly for me while traveling and when i was using it at work to multi-task on the tablet and laptop using the hotspot feature.i'd like to get the update installed so i can have the option to close out the app instead of it still running in the background,along with getting all of the new features of the ics update.
now here's the part that will cause some problems,i don't know much about androis os,so if anyone can help me,please treat me like an idiot so i can understand what i have to do to get things back to the way they were so i can do the update,or it there is another way to somehow push the update through in another way.once i get everything working again,i will leave the device un-rooted so as i don't have this problem again in the future if anymore updates are pushed to the device.thanks in advance for any help you guys can give.
here is the error message i get after the update has failed to install doing it ota:

I don't have experience with Xyboard 8.2, but one thing I think you can try is factory reset your tablet. Follow these simple instruction :
1 - Make a backup of all your data, you don't want to lose family pictures and your music
2 - Go to settings
3 - Go to security
4 - If I'm not wrong there's an option called "Restore Tablet to Factory State", which is what you want
5 - Do it

I never tried it on a Xyboard, so I can't tell if it really works or if it will completely brick your tablet (which I think it won't), I wish you all the luck
Cheers,

thanks,tried that a couple of times already.it did reset everything,but it wouldn't re-install the original evernote pre-installed app,so it still won't let the update go through.

Having trouble updating to 4.4.2

I'm on 4.4 right now and I just reviewed the ota but when it finished downloading, it went stock recovery and just said "error". Obviously I was pissed so I then went the adb root but that wouldn't work either. Something about it not being able to find "update.zip" when it is clearly in the same folder. After that I decided to flash a custom recovery, not clockwork but the other one. Whenever I try to go that route it still says it failed. I have been looking at posts and none have helped so far.

I am rooted, I don't have busybox/xposed, I am using art. I read something about having to have all of the stock apps. I had a modded playstore on here but I didn't work so I re-download one and installed it, could that have anything to do with my problems? And if so, where can I find another playstore app?
also, this is what it says in the custom recovery: /system/framework/core-libert. Jar unexpected E:Error executing updater in zip I tried googling but to no avail.

That modded play store might have changed some system files that prevent the update. You can try flashing one of the stock 4.4.2 Roms available in the android development forums. I used the one by bigxie.
