[Q] I need some answers about Nexus S

So I bought Nexus S from second hand recently mostly because it will get official ICS support from Google.
So because it's second hand buy, I really don't know if I'm using original bootloader, kernel, radio etc.
It's rooted (because I have Superuser app), I think it has stock 2.3.6 android (build number GRK39F) and kernel version 2.6.35.7-gf5f63ef, [email protected]#1.
Can someone who use stock android and original kernels confrime to me that this is right version?
I really want to update to ICS using incremental update which I found here (http://forum.xda-developers.com/showthread.php?t=1445635) but I'm affraid to don't screw something because of bad experience when I radio bricked my desire
Can I update it to ICS or I need to do unroot or something?

Just download the correct stock ICS rom for your device (if it is I9020T or I9023) ,put it on the SD root and then flash it using the stock or CWM recovery and be done with it (if you need the ICS)

most likely you won't be update by OTA because you are rooted (system file verification will fail)
just download stock ICS ROM and flash it ...

Ota will install fine if its a stock rom with just root. The update script basically checks that everything that should be there is there . If there is something else in there like su it don't matter.

flashing a new rom is the best way to go if you have cwm installed already

I succesfuly flashed ICS and first impressions are very good.
But I think I lost recovery...

flash a CWM recovery via adb , or there is TWRP recovery in DEV section , which is very good .

Cant update Android..

I have a rooted Moto G phone. It is android 4.3 , I cant update it to 4.4.2 Kitkat for some reason.
I saved Kitkat to the SD Card, loaded into Recovery mode on the MOTO, then tried to install Android 4.4.2 from the .zip file
saved on the SD card in my phone.
I cant get this to work and i tried to install CARBON ROM the same way with out any results.. it says ERROR and fails to install.
Any help would be greatly appreciated.
ALSO does android need to be updated to 4.4.2 to install CARBON ROM?
Thanks

I don't know but maybe can help...
I could update successfully to last minor 176.44.1 update only after flashing stock recovery.img from my exact stock ROM.
after rooting process on KitKat motoG my recovery was modified, restoring the stock one worked for me. I just updated ota normally in WiFi without problems.
after that I flashed cwm recovery.

I restored to stock recovery and removed root. After that applied KitKat OTA, then flashed custom recovery and re-rooted.
Sent from my Moto G using Tapatalk

this involve wiping of all data and a factory reset, so first try just restoring the stock recovery.
If not working make a good backup first.

If the phone is rooted, OTA updates do not work afaik...

Flashing a ROM overwrites system partition completely. You could have android version 1 running and still just flash another ROM

[Q] Official (not manual) lollipop OTA on unlocked moto g xt1033

So, the situation is I have moto g xt1033 with :- unlocked bootloader, rooted, stock rom 4.4.4 kitkat (i mean no custom rom). and fastboot flash mode 41.13 2014-06-16 and philz touch 6 clockworkmod v6.0.4.7
I want to know how to update to lollipop with official OTA update (not manually or sideloaded)?
Why I am asking this?
I got the prompt of official OTA available on my phone and then i clicked yes and downloaded the update. But when i clicked on install, it went in bootloop. It boots on the philz recovery mode and then nothing happens just restart again whatever i select.
As of now, as I backed up, I recovered to the before state of the phone. Do I need to lock the bootloader again or what? The official OTA update is not for me? Then how to get lollipop? I read the soak test etc threads but why not official update ?

Locking the bootloader won't do anything,so don't lock it
Ota update requires:
1.Stock firmware(unmodified and unchanged or tampered)
2.unrooted
3.Stock recovery
That probably happend becuZ your KitKat firmware was modified and you have custom recovery,root..
So just reflash the stock firmware
Do that on your own risk as failing this might brick your phone
Thank me if I helped

Thanks mate for reply.
1. I have stock firmware KK 4.4.4 (though xposed framework & few modules are installed currently)
2. Rooted
3. What is stock recovery? (m noob here)
And i guess reflashing the stock firmware wipes out all user data & apps, right?
Any other alternative which does not wipes out my data?

Actually there is no other way you could do it
i tried everything i could to stop the wipe procedure but it obviously wiped everything
you just backup everything you have got on your internal and external sd card ..
1.Stock Recovery:: Android devices come with Google’s recovery environment, which is often referred to as the “stock recovery.” You can boot to the recovery system by pressing device-specific buttons as your phone or tablet boots or by issuing an adb command that boots your device to recovery mode. The recovery menu provides options to help recover your device — for example, you can reset your device to its factory default state from here. The recovery mode can also be used to flash OTA update files.
2.Custom Recovery::A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. This is a bit like flashing a custom ROM like CyanogenMod — but, instead of replacing your device’s Android operating system, it replaces the recovery environment.
what you have to do is:
Find the Kitkat official update on the internet accrouding to your [Build number],[model number] [system version] you can get this information in about phone....
If you have asia retail then follow this method http://forum.xda-developers.com/showthread.php?t=2700502

ok Here what i am planning:
1. Uninstall all modules & xposed framework
2. Unroot using supersu
3. Restore/reflash stock recovery (just recovery not whole firmware as I already have stock rom)
4. Install the update either manually via recovery or using auto install.
Am i on right path? Pls help me on step 3, any link or step-t-step guide? I couldn't find one, every post is abt restoring whole firmware.
TIA. Cheers !!

Unable to get OTA Updates installed on TWRP - Need to go back to stock recovery

Hi All,
Background:
Installed TWRP recovery to downgrade to KitKat from Android ver 5.0.2 / COS 12.0 YNg1TAS17L
( I guess the changes in lollipop made me to do so).
But after installing TWRP, for some reason or other I did nothing and now the issue is the OTA are not getting installed. From other similar thread I know that we can download the OTA zip and install through TWRP and I am not looking to get into that...as I am giving this device to my family.
Help Required:
1) Is there a way to uninstall TWRP and go back to stock recovery without losing any data?
( Is it as simple as flashing recovery image from the Stock ROM?)
2) Using the OnePlus tool kit can we flash the stock ROM which will also restore the stock recovery?
(If so is it possible to flash the latest ROM 5.1.1 or CM12.1)
I just need guidance here with steps on what will be the best and safe approach without frying up my device.
Please suggest

Numerous other threads on the same subject... I don't understand why you are not ready to flash the OTA through TWRP but you are through stock recovery... It's the same thing... Don't use toolkit, they are the ones, in 99% of the cases, that "fry" your phone... As soon as TWRP is installed no OTA will automatically, you will have to flash them manually.

Hi Currently I am having Honor 4c with Kitkat 4.4.2 (V100R001C636B160) version I wanted to Upgrade my android version to Marshmallow(CHM-U01C432B560) or any other custom ROM. I have unlocked my device bootloader and installed CWM recovery following the guide https://forum.xda-developers.com/honor-4c/development/honor-4c-root-cwm-recovery-inshaalmirza-t3177770 was able to install CWM but I wanted to install TWRP and followed the guide by @HassanMirza01 but wasnt success to install TWRP , if I am trying to flash Marshmallow ROM using CWM or by flashing IMG files using ADB I am not able to do it. Every Time I try to flash a ROM from CWM I am getting error and while flashing IMG files using ADB the screen is being struck at boot logo.Can anyone guide me how to replace CWM with TWRP so that I can Install Marshmallow (every time while I am trying to flash TWRP it is being struck at boot logo and had to flash stock ROM to recover the phone) and install marshmallow.
Note: Initially I upgraded to Lollipop as the version was not stable and Buggy I reverted to stock version using the official guide.

You can try this TWRP https://forum.xda-developers.com/honor-4c/development/recovery-twrp-3-0-0-0-huawei-honor-4c-t3349495 or some version of TWRP for honor 4x or p8lite. And then you can try to flash stock firmare using this tutorial https://forum.xda-developers.com/honor-4x/how-to/install-emui-4-1-4x-4c-g-play-g-play-t3515702. You might need to be in lollipop or marshmallow to use it.

What error did fastboot gave you when you tried to flash TWRP?

No error given but after flashing twrp device is struck at boot screen and can't move to next screen cwm flashing works fine .
Is it mandatory to have lollipop or marshmallow update to flash twrp?

I don't know how things really work or why they need stuff to work. But in TWRP thread it says for android 5.1.1 - 6.0. So I guess it's important to have some of those versions.

Is there any other way to flash lollipop or marshmallow from cwm? I even extracted update.app and flashed recovery, system , boot images individually but it also doesn't work struck at boot screen. Can I fully wipe system files from phone and re-flash lollipop or marshmallow update. Similar to full format of a PC.

No idea will that work, but one thing that comes to mind is to flash those images you did and then put UPDATE.APP in your sd card in folder named dload and do force upgrade ( power + vol up + vol down ).

Tried that too but no success. I think the problem occurred while downgrading to kitkat from lollipop maybe it corrupted the boot system. Even that is the case while flashing and wiping cache so many times it might have showed error in any of the instances but it didn't. Can't find out what actually preventing system to update.
