Re-Stocking Nexus S 4G for OTA Update

Hi, I have a rooted Nexus S 4G with the stock rom but a different kernel and CWM recovery. I have received the OTA update for ICS but can't install it. I was wondering what I can do to go back to stock kernel and stock recovery to install the OTA update so I don't have to wipe all my data and worry about that.
Is it possible? Where are the stock kernel files and how do I do the recovery?
Thanks.

Nooooooooooooo

Could you please provide a working link?

Download these files:
2.3.5 Full ROM
2.3.7 Incremental Update.
4.0.4 Incremental Update (If you already got the update notification, you can copy this from /cache to the sdcard.)
Superuser.
Recovery Saver.
Flash the zips in this order:
504d...
2e8d...
TAMkDR3z
Superuser
Leave_the_twrp_alone
This will not work in twrp recovery 2.1. Use twrp 2.0 or earlier, or clockworkmod.
Protip: Some root apps requireBusyBox.

[Q] Unroot without full wiping

I recently realized that I use no root requiring apps or custom ROMs on my Nexus 7(while I keep my phone rooted for many a reason). Now that I hear the 4.4 update is being pushed, it occurs to me that all keeping a custom recovery and root on my tablet does is complicate updates. So I want to unroot, return my recovery to the stock, and get myself all ready to wait for the update to push out. What would be the best way to do this that does not require me to lose data/game saves/have to reset everything up?

Fastboot flash the stock recovery and don't worry about su because the ota will take care of that.

I am sure this has been answered somewhere and I did search the forum before posting but right now i am pretty excited about 4.4 and would like the experts to answer this regarding grouper :-
I got the 4.3 update OTA on a rooted 4.2. I later rooted the 4.3 but did not remove any default apps. I also have frano kernel installed and TWRP recovery. Does the kernel and custom recovery affect the OTA process? Am i safe for 4.4 OTA? or shall i unroot, install stock kernel and also stock recovery?
Thanks

You should be fine if you install the stock recovery before the OTA arrives

Open the SuperSU app on your device.. Go to the app settings and select the option to unroot/clean up.. Reboot. That is all.

Yes, you'll want the stock kernel and stock recovery installed.

On grouper, it can update independent of changes you have made to the system and recovery. This isn't true for all other nexus devices, for example, mako. Doing the 4.4 update will get rid of root for you, but it will flash fine even if you have a custom recovery. You may need to flash stock recovery manually if you don't want custom recovery anymore.

In the past, that has failed for me. I'm still one update behind on 4.3 because it would not install and I was too lazy previously to unroot and get it to install.

Do you know where I can find the recovery itself? Only ones I find in my searching are TWRP and Clockwork.

Did you ever find the stock recovery? I'm looking to unroot without losing my app data..
PS, sorry for bringing this back from the dead, but it is exactly what I am looking for.

Hi, afraid if you've root on your device, more importantly, you have a custom recovery partition in your device, do not accept OTAs. This could permanently brick your Nexus 7. You may be able to temporarily "unroot" the device, removing the custom recovery and flashing back to full stock with stock recovery. Check your device's threads for any available guides.

you don't really need to go back to stock. when the ota becomes available, either here on xda or when it's available on your tablet, download it then install it through the recovery on your tablet. you'll lose root but just flash a root package and you're all done. i've done this before and no problems what so ever.

that's a custom rom or a modified stock rom. no one has got an ota for the 2012 nexus 7 and were the only nexus still to get 4.4.3 through ota. i'm also waiting but it's weird for there to be a gap from the other nexus's

I would recommend that one, as its basically rooted stock which is what you're currently running anyway. You can just wipe cache and dalvik cache in recovery and flash it, no need to wipe data (so your apps/settings/files will all be untouched). If there are any questions in recovery to flash stock recovery or fix root just answer no to both, my root was kept intact without having to reflash superSU. It saves waiting for the OTA (which still isn't here for some reason) and the risk of it failing/losing root/custom recovery for whatever reason.
As always just in case, make a full nandroid backup in recovery, then flash the ROM. You shouldn't have any problems. :good:

Thank you Sir!
Okay, correct me if I am wrong:
if OTA updates available, do not proceed to DL (over WIFI) and do not let tablet do the installation, as it might cause problem (brick?).
DL thru XDA install thru recovery instead. ( either in ZIP or .img? format).

You'll probaby get a status 7 error and the update won't apply, I would recommend the rooted stock based ROM you linked to above, quick and easy to update rather than waiting for an OTA and trying to update that way.

Its 4.05 bootloader still. Somehow in the zip its called bootloader-flo-flo-04.05.img
There's a new kernel, some changes in the source. Its compiled March 21
Not much else changed

Has any one got the ota yet ?

@Vkk187
ofc not.
Flash the stock image with NRT and check "dirty flash" and that will not delete your apps and data.

Yet to unlock my BL ...I know it's simple . Will do it some day [emoji18]

AonI updated to 5.1 rooted stock via TWRP a couple weeks ago.
Today I just got this update notification for 5.1
Is today's notification for 5.1.1? Because it only says 5.1

I just completely flash-all every time a new build comes out as I do not know how to side load using NRT or TWRP (am I wasting my time on doing it this way). If someone could please explain to me how to side load I would be forever grateful. I have searched and cannot find clear instructions or walk through on side loading

Having read wugfresh page,it says Since lollipop,its hard to sideload OTA now. I myself try it last night with my rooted stock recovery,it fails to install the OTA from google,even if file has been downloaded automatically. Its harder to get OTA install smoothly nowadays especially if you on lollipop. No choice had full flash without wipe. And reroot again.

Actually, it's just as easy sideloading as it's always been. The difference is that you can't sideload an OTA (or receive one in any way) if you've done any kind of alterations to the system. This includes rooting and/or flashing custom recoveries and kernels. Even if you unroot there are still residue alterations in your system, meaning you'll have to do a full system flash anyway.
It's worth mentioning that unlocking your bootloader does not prevent installing an OTA.

I have managed to root the device but TWRP is not working on aboot 5.0.2. You can see the post links below.
It is merely few commands on 5.0.2 to run recovery by downgrading your aboot to 4.2.2 but then, Lollipop wouldn't start and you will need to reflash aboot 5.0.2.
So basically it is a choice between Lollipop rooted without recovery or Kitkat with root & recovery. I think we are not flashing anything as yet so it would not be much of a problem actually to not have a recovery. When we do need however, we can downgrade our aboot and flash twrp using loki and then flash the rom we want to.

Yeah I recall rooting it first time. Pain. All the Loki this Loki that.. Asking bc I upgraded my KLTEVZW by way of a flashable zip (4.4.4-5.0). Thought it may be possible on G Pad?

How about you root and make a twrp backup. Win, win

It's not a rumour. It definitely exists. It won't matter what recovery you use or what version as to whether you need to swap aboot.img versions temporarily if you're running stock LG Lollipop, if that's what you're wondering. 4.2.2 aboot.img lets the custom recovery boot, anything newer doesn't. And stock LG Lollipop won't boot on the 4.2.2 aboot.img, so you have to swap the new 35A_08 5.0.2 aboot.img in to get the ROM to boot.
I'm guessing the dev who made the newest TWRP for the VK810.4G is waiting to release it to the public until/if he gets CM 12.1 completely straightened out for our device. He'll probably release both at the same time.
