[Solved] How to revert 2.3.6 stock from ICS? - Nexus S Q&A, Help & Troubleshooting

I'm sorry for the dump noob question, but how to get back to 2.3.6 (stock, without root) from ICS?
I tried install from recovery with update.zip but without light on the screen i can only see that it says that installation is aborted.

Use fastboot to flash custom recovery. And then flash the full stock 2.3.6 and await the OTA.

please how can i do that?i mean the fastboot...i cant find something hours now.thanks

You can now flash a custom recovery without using fastboot, take a look at the thread linked below, read it carefully, make shure you flash Clockwork 5.0.2.3, also make shure you use the correct FULL rom for your device.
Flashable Clockwork Mod Recovery
ALL Nexus S OTA Updates for ALL Variants, Plus Full ROM Packages

Yes thanks, i figure it out, you need to download SDK manager, and load clockwork mode recovery, then grab 2.3.6 update and recover it.
Thanks, mark as solved

Some say even if screen light is too dim in the stock recovery try to do it in the sun and it will show up lol

Desire s stuck after 2.3.5 update

i tried to update via phone (after the notification), but after green bar was full, my phone rebooted and stuck in white screen with htc logo... if i try to enter in recovery i see this
h*tp://i39.tinypic.com/xdxnc5.jpg
it seems to be s-off (i bought it used) ...what have i to do for make it work again??
tnx.. and sorry for my bad english
same problem here, help is needed!
A golden rule: never update OTA on a modified device (custom ROM even modified Stock one, custom Recovery, Revolutionary hboot!, etc.)
How to fix:
do not pull battery!
flash a custom recovery (e.g. 4EXT) with the fastboot command (search for a how-to)
reboot to recovery, wipe all partitions and install custom ROM
Ok, to late with the battery, have already pulled that one out!
I also have S-Off on my phone, really dont understand the how to fix a recovery??
And is it really neccessary to flash a new ROM for this?
An official release that screwes the phones up?
I think the general issue is that an 'Official' OTA upgrade should not screw up your phone - enough testing by HTC should make sure of that.
Hoever, if you have modified your phone (e.g. by rooting it, installing custom recovery etc) then you can not expect to blame HTC when their upgrade doesn't work as expected. They can't be held responsible for problems caused by modifications you make to the phone.
But all I have done is S-Off, I have not installed another ROM or anything else?
So the update should work I really think!
Can I install a custom recovery without have to be able to start the phone?

The OTA flashes a new hboot also.
If you S-OFFed with Revolutionary your hboot has to be version 6.98.000x. This hboot has a protection and cannot be overwritten. This is the point where the update process is interrupted. The result is a bootloop, because the new system is incomplete.
If you can boot to bootloader (hboot) you should be able to flash a custom recovery with the fastboot command (in the 4EXT Recovery thread there is an attachement - a zip file that contains recovery.img). Extract the archive and flash it with this command from cmd (there is a guide how to make fastboot working in my signature):
Code:
fastboot flash recovery {path to file on your PC}/recovery.img
If this works reboot to recovery, wipe all partitions and flash a custom ROM. Then your phone should be working again.
Then if you want the OTA flash a 0.98.2000 hboot, then use the 1.47.401.4 RUU (if you are using European unbranded) or the corresponding for your brand/region to return back to complete Stock and S-ON. Then you will be prompted to update and you will have the latest OTA on your device
Okay, I have now fixed the 4EXT Recovery and it is working!
Do I have to put a new ROM on the SD-card or is there another way to install a ROM (from cmd with the ROM on the computer etc?)
I dont have an adapter to the SD-card, but maybe I can put the ROM on the sdcard with a command in cmd aswell?
What ROM do you recommend to use? (sense, no sense doesnt matter)
Edit: I did a backup as well, thinking that I should do that...
Can you link to zip file you used for recovery i have exactly same issue and same software versions as you have.
@ Mooler. First of follow the guide that was posted here regarding the adb-drivers.
After that download this: http://forum.xda-developers.com/attachment.php?attachmentid=631186&d=1308596026
Then install that one as described with the cmd-command.
After that just put a custom ROM or a shipped ROM on the SD-card, wipe data/cache and install the ROM you want. That solved the problem for me!
Good Luck and thanks for the help I got here! Xda always delivers
Damn this phone! After hours of fixing with this problem!
I managed great, installed new kernels, radios, ROMs etc. And the first thing I did was to drop it on the floor so the whole damn display cracked!
Thanks for both of you.
I managed to restore the phone quickly after i got the correct recovery file. 30 mins and custom ROM was up and running. Good bye official update.
Akerhage: sad to here, it really was hours of reading and trying before you get it right.

[Q] Help with KJ2

Okay, so my phone came with this build number already, KJ2, it's a sidekick 4g, and i successfully rooted it, but i wanted to install custom roms and other kernels to improve performance.
From what I understand, you need to have cwm to flash custom roms, I think. Well thing is, i can't even flash cwm. The phone already came with recovery 3e, which cannot install unsigned packages or whatever... and i see the only way to downgrade to 2e from what i've searched, is using that CF-root zip file, but well, there's no such file for KJ2.
I have wasted 2 whole days just trying to do this and trust me, i have searched, and i know how annoying it can be for noobs to be posting questions here, but sorry, i really have searched all over the place and i'm making no progress. I can't even get past flashing a custom recovery in order to flash other kernels and roms.
Is there any possible way to do what i'm trying to do?
since is rooted go to krylon360 dev thread and download the update and the recovery thingy then go to youtube and type sidekikc 4g all in one and it should be there and download and only hit the batch file
i did that, but it just boots to the normal recovery, not the clockworkmod. also if i pretty reinstall packages, having already replaced the recovery file and put the update.zip in the sd card, it tells me signature not verified, and the installation fails. also everytime i'm in recovery mode, at the bottom it says manual mode, and it says appling multi-csc, installing multi-csc, and it's just there, literally forever, nothing happens.
U got to use the fake flash by sdduvick on that thread
Sent from my SGH-T839 using XDA App
well i have a new problem. i used odin and switched the firmware to KD1, but the recovery is STILL 3e, not letting me do anything. how can you downgrade 3e to 2e?
Im not the best with this but did you repartition? Would that fix the recovery problem if so?
you mean repartition on odin when flashing the firmware? yeah i did that, and the recovery mode is still 3e, which will never let me move on. oh well...i see not many people know about this problem, i'm just one of the unlucky ones
In order to downgrade your recovery, you will need to use Krylon360's modded recovery.
Use my script from this post: http://forum.xda-developers.com/showpost.php?p=15831175&postcount=124
double click on the .bat after enabling debugging on your phone (Settings>Applications>Development>Enable USB Debugging), it will set up recovery and reboot you into recovery, you'll need to press "Reinstall packages" to get into CWM.

Upgrading to CM7

I currently have a 2.2.1 based rooted rom and recovery is installed.
If I want to upgrade to CM7 rom, can I flash it straight via recovery ?

Read their installation instructions. It tells you what you are asking.
Samsung Captivate Full Update Guide
I read the CM full install guide. Just want to confirm that if I have recovery already installed on my phone I can skip the recovery install step.
Some posts I have read suggest that a GB bootloader is required before a GB based tom can be flashed. not sure if this applies in my case.

From the install guide:
Installing the ClockworkMod Recovery
"If the Samsung Captivate is already rooted & has ClockworkMod Recovery installed, skip this section"
So yes you can skip the recovery install step.
From reading a few posts that I searched "CM7 Gingerbread Bootloader" it appears if you have froyo/eclair bootloaders it will work. If you have gingerbread bootloaders...... it will work. The key is not to mix them. Once you go to Gingerbread bootloaders do not flash back to a 2.1/2.2 rom using a one-click that includes the bootloaders.
This link is a post containing many one-clicks that include bootloaders and those that do not.
Good Luck.
Just checkout the CM7 captivate page and you will get all the info you need.
CM7 page in this forum ?
I have seen some videos on Youtube where flashing a GB rom included several steps including backing up EFS data and later restoring it.
Is this required if I upgrade to CM7 by flashing a ZIP via recovery ?
No it's not required. It's up to you whether to do an EFS backup or not before flashing another ROM.
I suggest doing it once the first time you install a new ROM, just in case.
EFS backup is simply copying a folder over to the PC ?
The EFS folder appears to be empty when I look at it using any file browser. Is that normal?

Going to root, am I doing it right?

I am on stock 4.0.4 with a locked bootloader. I want to have root with the stock rom, nothing else just root.
So I am gonna use the tool provided here,

I have already installed drivers and have the tool downloaded.
Then I would like to flash the stock google 4.0.4 rom that will let me receive OTA updates. Is this the right file?

I heard there are problems flashing stock rom with CWR if the stock recovery isnt removed? Thats why I dont know if I should flash the stock image.
Is the process of flashing rom with CWR recovery the same as with stock recovery?
My phone is the i9023.
Thanks a bunch in advance.

Sorry should have specified my phone in the OP.
Best way is to do it manually. You can find all of the steps required here. The only difference is that you should be flashing the latest recovery from here and the latest superuser.zip file when flashing with recovery.
Note, unlocking bootloader will cause loss of EVERYTHING on the device that you have put on there (sdcard, apps, data partition, etc).

You suppose thats better to do manually so I will have latest version of recovery and superuser?
And yes I am aware of the data loss waited sometime to finish all my games now I am ready to lose all my app data.

Do it this way. The one click is fine but using Android SDK and going through all that will help you in the long run. This way you know the process in case something goes wrong. It may be confusing at first but worth it. It will teach you a lot more than flashing a one click!
I learnt a lot from this and feel much more experienced and capable because of it. I know I will be able to solve any major issues using Android Debug Bridge (adb).
Okay then I am gonna try the manual way and gonna take out time for it. Now I just need to know what do I flash once I have unlocked bootloader and installed CWR?
I just want the stock google rom and receive OTA if nexus S continues to be supported by google.
You won't need to reinstall the ROM if you are currently on 4.0.4. The ROM stays there as-is. Feel free to do your wipes in recovery and reflash stock 4.0.4 through CWM if you must. You flash CWM to your phone and then superuser through CWM.
Steps:
Setup ADB/fastboot
Bootloader --> fastboot oem unlock --> agree
Bootloader --> fastboot flash recovery recovery.img --> this will give you CWM
Recovery --> flash superuser.zip and, if you must, wipe and reflash ICS (flash su AFTER this if done)
Reboot --> bingo
Also note, with stock ROMs it will replace your current recovery with stock recovery on each boot. If you want to keep CWM, delete /system/etc/flash-recovery.sh when you first boot. You'll have to reflash recovery afterward and it will stick.
Oh I was of the impression that unlocking bootloader wipes everything means it wipes the OS as well. That is nice if it's just data and not the OS, dont think I would reflash it if it's not needed.
Can you explain what you mean by will have to reflash recovery? I will have to do that even if I delete that file on first boot? And whats the drawback if I dont delete that file and stick with stock recovery?
As soon as you boot into stock android it will replace the recovery. So if that file is there on first boot, it will replace it while booting and you will be without CWM (stock instead). After first boot you can delete the file (you can reflash a ROM which has this deleted, or delete it yourself from a stock ROM, or even use adb or a recovery-based file manager to delete the file, then you won't have this problem at all) and it will no longer reflash stock recovery, but you would already have the stock one and need to flash CWM one more time to get it to stick. Easiest way is to just flash CWM and delete it within android imo, saves mounting commands and the such.
No downside really. If you need to flash something for one reason or another you'll just have to reflash CWM before you do so. Once rooted, ROM Manager can do this for you within android anyway.
I had already downloaded and installed the drivers from the one click root thread and my computer shows the android adb thing when I connect my phone with USB debugging.
But as you guys suggested I am gonna do the manual way. So do I just skip the installing driver on computer in the part 1 of this guide?

Because you have a Nexus S with amoled. That's the i9020. The i9023 is SLCD.

He has the i9023 to my knowledge. It is completely normal, though. Bootloader and recovery for i9020 and i9023 series are the same, this can be attributed to the issue with 4.0.3 recovery backlight not turning on.
If fastboot recognises your phone in the bootloader (the fastboot menu), your drivers are installed an working perfectly.
Finally got to the unlock bootloader screen, didnt do it just yet but now I know how to do it.
I must say the guide is a bit outdated, the software has changed quite a bit seems. The most frustrating part was that the fastboot file is actually in the platform tools folder instead of the tools folder which I didnt figure for a while. I will hold off rooting when I have a whole day off because once I lose everything I would be very anxious to get my phone back to normal which will take time.
Thanks for the help harbb, if I have any problem flashing recovery and superuser I will come back for more help.
And yes I have the LCD version i9023.
Btw the guide said the fastboot will be in the tools folder but the tools folder had a read me that "adb has moved to the platform tools folder" this is how I figured to go to that folder and thats where the fastboot file actually was.
Now it says I should put the recovery image in the tools folder so should I do that or put it in the platform tools folder?
In the instructions for the flashing recovery I am not understanding one thing.
6 - Then back on the SNS select Power Off (Reboot also works)
Part 4 - Root
1 - Power ON the SNS
So after flashing recovery I have to reboot? Since I am on stock rom that would bring back the stock recovery so how would I flash superuser then?
If I delete the stock recovery can I still get OTA updates?
fastboot and adb is now in platform tools, that is correct. Easiest way is to put your recovery in there too so you don't have to type in the absolute file path to it, don't put it in tools.
Don't power off or reboot the phone. After you flash recovery go straight into the recovery menu and root, flash custom ROMs, kernels, etc. You can transfer files to flash via the mounts and storage --> mount usb storage menu. After this feel free to reboot.

[Q] CWM recovery issue with Rom Manager

So I just rooted my Verizon Galaxy S3 and unlocked the bootloader. I flashed Clockworkmod recovery using Rom Manager to update to the latest version. Made a nandroid, installed Titanium Backup, linked it to my Dropbox and uploaded. I downloaded the latest CM10 nightly to flash but the stock android recovery appeared instead of CWM. Found some info that I need to flash a clockwork compatible kernel first. The questions I have are: If I install the latest CM 10 nightly will it automatically install a clockwork compatable kernel? If not, where can I download it from? and if I do need to flash a kernel first can anyone give me detailed instructions how to do this as i'm relatively new to this stuff and don't want to brick my phone. Thanks, any info would help.

I did, had it unlocked and rooted. I guess there was some sort of issue with Rom Manager on the S3. I use it on my Galaxy Nexus and have no issues. I ended up abandoning what I was doing, uninstalling Rom Manager and going a different route. I have no prior experience with Odin but figured out how to install CWM . Downloaded I535vrblk1, flashed CWM, unlocked & rooted again. . Thanks anyway for the reply.
You can reinstall ROM Manager. It is something to do with some of the newer OTA's and the leaks. I have read a few posts in the forums about this in the GS3 and I really can't remember the fix but your recovery not sticking had nothing to do with ROM Manager. I think the fix was when you rebooted to recovery to flash a kernel right away, whether it be KT747, LK, or any of the other. Now that I typed this I'm about 99% sure that was the fix. Like I said above though, it has nothing to do.with ROM Manager, so if you're like me and find a lot of the tools in it handy you should be able to reinstall it. If you have a problem again just flash a kernel.
