[GUIDE]One Click Return to Stock i9020t/23

This script returns to unrooted, factory state android 4.0.4.
1. Download this zip - Quicker download here:
http://www.mediafire.com/?pzrzrt3583rgbmf
2. Backup your phone (everything! sd, apps, games etc).
3. Plug in your phone, turn on USB debugging.
4. Unzip the downloaded files.
5. Open run.bat
6. Type in Y then press enter.
7. It does the rest.
Had to do this since i'm sending off my phone to samsung, basically used this:
http://forum.xda-developers.com/showthread.php?t=1167819&highlight=unroot
and updated the images for 4.0.4 and for i9020t/23 (this won't work for nexus 4g or i9020a). It worked well for me so I thought someone else might find it useful.
If you're having problems it's probably because you haven't installed the windows drivers correctly, I can't really help you there (google it or something!)
If you want to thank anyone, go to the other thread and thank michaelpeerman. All credit goes to him.
Edit: By request, someone wanted the same thing but for 2.3.6, so here is the link for that

Hi there!
Is the One CLick 2.3.6 edition compatible with 9023?

I have a i9020T stock 4.0.4 never rooted. If I run the 2.3.6 script,will it go back to stock 2.3.6 without problems?

My understanding is that you require root to flash any ROM, this would be no exception. It wouldn't be that hard to root and then run the tool though.

But there'll be no problem rolling back to 2.3.6 from stock (rooted) 4.0.4?

Hi,
I got a really f******g problem with my NS. The power button is out of service. Thus my only aim is to get back to the unroot locked bootloader rom in order to send it to samsung.
I tried to do that manually with cmd.
I tried via Odin
I tried via your one click zip
I used my computer (the one i used to root it for the first time, guessing the drivers didn't change). Everytime, the command got stuck at 'waiting for device'. I thought it was a driver problem, tried to reinstall sdk, reinstall drivers. I'm still blocked at waiting for device.
I tried with another 'virgin' computer. I installed PDAnet to get drivers and make sure they work. (tried CMD or with your one click zip..) I'm still still stucked at waiting for device. However, my device do is recognised by both computers..4
Any idea?
Is my ****ing power button messing around?
Two days i'm drudging on this.. I'm thinking about suicide by now..

Sorry mate I really have no idea, maybe you could try calling up samsung and ask them if they would repair it even if you rooted? It is a developer phone and so they must understand that most people with a Nexus S root it..

I'm looking to sell my NS so wanted to get it back to stock and this script worked perfectly. Thanks so much!

[Q] Unroot to get OTA

I rooted my father's O4X HD using the System Backup App method. I then used that app to boot into TWRP. (TWRP isn't permanent). The bootloader is locked. Basically, the phone is stock except it is rooted.
He is running ICS and would like to update to JB. He doesn't care that the device is rooted and he doesn't use the root.
My question is: Can I completely unroot with SuperSu, then update via OTA?
I've done countless hours of research and I cannot get an definite answer. I will be trying to unroot, then applying the OTA update tonight. Are there any risks involved? If I do brick it, how do I reflash the stock ROM?

If I'm wrong then I'm sure someone will correct me, but the JB update isn't avaliable via OTA. It was released to be flashed manually from a PC only.

as far as i know you only can update via lg pc suite to official JB.
or flash it via kdz/dz
but woth lg pc suit you will get 100% the right rom for your country/area.
and if you softbrick it there is a tut in general section how to recover it. but there is a low risk that you brick it. I don't know if the official pc suite needs an unrooted device. just do it via SuperSU should do it.
good luck

Thank you for your response. Let's say I'm talking in general, if I used that method, would it be possible to OTA? I'm worried when the update is released I might brick his phone or I won't be able to update...

actually not. only baseband will be different but i hadn't any connection problems with that i tested. but if the provider of your fathers phone has his own rom there are some preinstalles apps you may find useful.
and if you flash it via pc suite and something goes wrong lg has to reflash the phone for free (warranty, at least as far as i know, im not 100% sure). But unroot it before. just to be sure

If you fully unroot then you should be able to upgrade by OTA to whatever was the latest v10x code (ICS) for his device.
Two useful sites;-
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=abcdefghijklmnopq
Replace 'abcdefghijklmnopq' with the device IMEI to find the latest v20x code that you can get if you want to go down that route.
http://lg-phone-firmware.com/index.php?id_mod=15
List of all firmware available, check what the latest v10.x code for the device was and you'll see if there is any reason to unroot and check OTA.

Xperia Z3- How Do I Downgrade to KitKat 23.0.A.2.98 So I can Get Root?

Could not downgrade to get root
Hi all,
I'm a very big fan of this community, but only to read and learn. But now I need your help...
History: rooted my phone few months ago in the way told in this post. Everything went well, but last week my screen broke. Sony fixed it but also put latest software on it... and removed root.
Today I tried to downgrade to KitKat 23.0.A.2.98 again (stil had the FTF) to get root again, so I can put back my Nandroid backup. I didn't manage to get it working... after restarting after flashing when the blue screen appears before you are asked to unlock your SIM... my phone makes a pitching noise for 10 seconds and then reboots again. The process repeats itself again and again.
Fortunately I can flash the latest firmware back and my phone works again... thank God because a thought for a moment I soft bricked my phone.
Anyone a solution to get root? I'm now on LP 5.1.1
thnx!!!!
ciao
Valentijm

How did you downgrade? The normal way... means: using flashtool (latest version) and which settings did you use for flashing? ...and did you try downloading a different version and flashing it?

Hi Tom, yes I did it the normal way... latest flashtool and settings the same as before, so I checked no boxes. After that didnýtwork I tried something different, so checked all wipe options. I also tried a different version and flashed that via the normal way. That didn't work either... the only flash that worked so far was 23.4.A.0.546 / R7C. But that's way to new to get root via downgrading

So the flashing process did always work without problems? But the result is always as you described?
And if it's only about root... did you try Kingroot? Afaik it is supposed to work on almost all versions.
Another thing: I don't remember all options by heart (and can't check them atm)... but maybe try some of the provided options.

It's more that when I reboot after having flashed back to earlier FW my phone bootloops... so I don't even get a chance to continue and root. Very annoying!
My next move is to find another old stock FTF (probably not a Dutch one) and will try to flash that one with different boxes checked.

When I'm back home I can check for the one that I used (quite recently) when relocking BL and rooting etc. If I don't find the source anymore, I can maybe upload it for you.

Ok... so this was the version that I used... to downgrade and root:
D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917.ftf
try this link maybe:
https://mega.nz/#!f5pXVAIZ!nWmaFU9d5ux6FOUI6Kdv3GK8RObswoZzxRwpQVEvpxo

There's an easy way to get Root on 5.1.1 without having to downgrade back to kitkat
- Unlock your bootloader on Sony's Website
- Search for a custom kernel here that is for 5.1.1 ( e.g. Androplus, etc )
- Boot into fastboot mode in Flashtool and flash the kernel
- You now get recovery because the kernel comes with a custom recovery
- Flash SuperSu's latest Zip file to get root
- Enjoy

Maybe be careful when recommending that without mentioning, that he would loose his DRM keys in that process... so I would always add the comment, that he should have a backup before unlocking. Or at least mention the loss of the DRM keys as a warning.

Note 5 Reboot and All apps crashing

Dears, thank you all for your efforts in making this website the best ever.
I just bought a new Note 5 (N920C) couple of weeks ago, and suddenly it went crazy!!
All apps began to crash and the phone reboots million times.
I tried all means of wiping, recovery, i even reinstalled the stock firmware, changed kernels, still the same problem, (latest kernel is SpaceX-Kernel-v0.1_N920C(official) still no use.
Now the thing is my knox counter is up by 1, and the warranty is void. :crying: any way i can reset it to send it back to samsung, or if there anyways to fix it it would be better as they will take two weeks min to repair it.
PLEASE YOUR HELP......

can you enter download mode??? (down+mid button+power)
if so i can recommend a couple of issues;
1) enter download mode and by using odin download the factory rom from sammobile.com... Select your country (turkey?) and find the appropriate rom there
2) flash the phone
3) with the same mode connect to pc and by using smart switch try to update the firmware (There is an update if i am not mistaken)
4) see what happens
good luck

Brother thank you for your help, I've tried every single thing, and i guess i came to a conclusion where its the google play services app that causes all this hustle.

I had had the frequent rebooting issue with Space kernel then I installed the root-able stock kernel and the issue has been in the past ever since

knox is a software and hardware based fuse if it gets tripped there is no going back.. Even the great developer chainfire (mastermind behind flashfire, cf auto root and supersu) confirmed that knox counter cannot be reverted back..

I upgraded to OJD yesterday, same issue, almost all apps have sopped working, I fixed this with re-install kernel and wipe cache in recovery, not sure which one is the correct solution, just try this, thanks.

And I can vouch for that site. I had to buy the newest AZ to fix my baseband.

Do you still need this one? I would be glad to help.

Thanks to @johngr77 for pointing out J320AUCU2AQC1 was available to download for free. It's now in the OP.
J320AUCS3AQG1 is the current att firmware, if anyone comes across it please share.

Found the AQG1 on one expensive paid site, so maybe it would appear somewhere for free:
http://www.sams-eng.com/index.php?a=browse&b=category&id=299

nice. In the mean time I added the OTA posted by @SBCarr
But please read post #2 before installing...i really put it here more for recovery reasons, cause if you're on J320AUCS3AQG1 and have to recover, you'll have to use AQC1 with broken baseband then upgrade using the OTA... and if your like me with no att sim, this is the only way

If my J320A isn't rooted, can I flash the stock AQC1 to AQG1 OTA file through the stock Samsung recovery ?
If yes, will there be any side effects?
Thanks

I'm going to assume no, but am unsure... maybe if you used the original file posted by sbcarr, mine was edited. But the issue is stock recovery flashes it from /cache/fota directory. stock recovery also at some point refuses to install from sd, sometimes it will let you tho

The AQG1 OTA download link is broken. @DamienMc

Late last night I used it and it failed, fiddled around a little and I was bricked. So I just pulled the link till I looked into it... want to test it? Lol

Ok links are back...the AZ ota was fine. but the A ota would fail if rooted without kingroot, with kingroot was fine tho. Weird?
I just edited the updater script more and everything is good now.

I was able to use the eng_root kernel, which technically isn't modifying your device, to push the AZ ota to my phone. But I had the legit db files to start with. When I get time I'll see I if I can't spoof a A ota db file and see if I can get it to update

AQG1 became avail. also on (paid) gsm-firmware, so maybe it'll show up soon somewhere for free
http://gsm-firmware.com/index.php?a=browse&b=category&id=10158

Figured out how to pull the firmware from smart switch, but could only get AZ, then found it here ... I'll add it to the OP a little later.
If anyone is on stock att on AQC1 feel free to inbox me and I'll help get the AQG1 files

I'm currently on AQA1(J320A), but if I'll have the AQG1 files, I would flash to AQC1 then to AQG1, or should I be on AQC1 to get AQG1 files ?

Using smart switch I don't think it matters which your on because it's the full firmware, ota just patches files so you need aqc1... if you're not rooted hook up to smart switch and see if it says there's an update available and which one it offers

I hooked up my phone (AQA1), and smart switch says "up to date", and doesn't offer anything.
I read on XDA that there is some method to trick smart switch using a free program called Fiddler.

Hmm ok it's not just me then, thought it was cause of my baseband or sim card. I downgrade to apj2 and it says the same.
Think that fiddler trick just spoofs your carrier, and that's what we're after att specific firmware

If I will upgrade to AQC1, is there a method to get AQG1 (no root)? do you know one ?

Wait your not att?
That's why smart switch didn't work.
I don't know a way besides official ota

Thank you for this. This helped me recover my SM-J320A It was showing baseband, IMEI and IMEISV all Unknown, and Sim Card not detected. After using Flashfire I flashed with J320AUCS3AQG1 **see post #2 (OTA) and then Flashed J320AUCU2AQC1 (newest available) and now everything is back to normal and working great.
BTW I am still learning and Unfamiliar with OTA. What exactly is it and is it needed? I tried to do some searching on google but no information came up. Reason I ask is I read post #2 but was unsure what it exactly means and what the proper way to do this is. Since my phone is now working I didn't want to break it just yet again LOL.
