There is very little risk involved since the return to stock package does not contain bootloaders. However, returning to stock will not reset the flash counter, as only the jig will do that. As long as you are not returning the phone under warranty, the flash counter is of little consequence. It has no effect whatever on the function of the phone.

downloading stock UCKK6 for i777 without losing data

I had 2.3.6 UCKK6 before I rooted my phone.

I rooted with method described by galaxys2root which was written for 2.3.4 and it broke my wifi. I only downloaded his zedomax kernel for rooting via odin.

I want to return to stock 2.3.6 kernel for i777 without losing system settings, apps, app data and user data. Is there any way of safely reverting to stock without losing these data? I see that all of your packages are kernel+ROM which needs a factory reset/wipe.

If there is a safe method, can you please direct me to link for 2.3.6 UCKK6 stock kernel for i777?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
There is a stock plus root UCKK6 package in the Unbrick/Return to stock thread which is a sticky in the development forum. You can try flashing that without a wipe. You will know right away whether it works ok, because if it doesn't, things will be broken, and you will get for instance force closes, etc. If it doesn't work, then just go ahead and do a wipe and you should be fine.

I would suggest that you first back everything up that you can't manually restore, however.
[AT&T Samsung Galaxy S II SGH-I777] AlwaysNoob:
I do not want to wipe the device. Any way of downloading just the kernel without wipe? The package posted in unbrick/return to stock is kernel +ROM.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Extract the zImage from that archive and install using adb or android terminal emulator. You need to be rooted.
[AT&T Samsung Galaxy S II SGH-I777] AlwaysNoob:
I am rooted. I am not very familiar with adb or Android terminal. However, I have mobile Odin lite. Can I download just the UCKK6 kernel without risk of wiping the device after or losing system settings? I have zimage extracted from the UCKK6 package and waiting for your green signal.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You can install just the zImage with Mobile Odin Lite. As far as I know, the UCKK6 kernel will work with the UCKH7 system binary. But why would you want to do that? I recommend that you stay on UCKH7. If you want to remain stock but improve the kernel, then install Entropy512's Daily Driver kernel only, using Mobile Odin Lite. That will give you ClockworkMod Recovery, improve your battery life and overall give you the best of the stock experience. That is exactly how I have my son's phone configured, since he is not technically minded.

Yes, you can install either kernel without a wipe.

I bought my Samsung Galaxy At&t today and of course like a giddy school girl i came home after work to well root my phone,little did i know the following would happen :(

Only screen i can boot to says the following:

"Firmware upgrade encountered an issue. Please select recovery mode in Kies"

I know Kies is a pos so i of course came straight here, i tried using the download on page one but i'm getting the following error:

Sorry i can't post an image im new here.

I didn't flash any new rom,it still had the At&t stock rom :( i've been trying to find an answer for the past 5 hours now and i'm ready to hang myself XD

Can anyone please help me by pointing me in the right direction. Thank you.

I was trying to flash SGH-I777-ATTGalaxyS2RootStockZedomaxKernel at the time :( it failed and then well this,phone will only boot up to the message above.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You're not the first person to report a similar problem after using the zedomax kernel from galaxys2root.com. To be honest, I'm not exactly sure why that package causes the fail, unless you actually have the I727 instead of the I777, which was the case with one person. If you have the I727, then you are in the wrong forum.

If you do have the I777 then the files you will need to recover your phone are in the Download Repository, linked in my signature. It's after 11:00 pm and I'm going to bed. Tomorrow morining I am going on the road and will be out of town for the weekend. I probably will have occasional internet access but not very much or very often while gone. Maybe someone else here can give you some good advice.
[AT&T Samsung Galaxy S II SGH-I777] yrrtni:

Can't install updates; will return to stock help?

I rooted my phone some time ago (don't recall which method (and unlocked it using Galaxy S Unlock, if that is relevant).

I've tried a number of times to install OTA updates available from Samsung, but, after reboot, it always says "Install interrupted, The software update could not be installed at this time." But then when I check Software Update, it says that my "Current software is up to date."

Three questions.

1. Why is the update getting interrupted?

2. Why does my phone say the software is current?

3. Is there a solution for this problem, e.g., return the phone to stock?

Many thanks!
[AT&T Samsung Galaxy S II SGH-I777] geomax45:
It may be because the update detected root and aborted. I was running rooted stock 2.3.4 and could not complete the update, thank heavens!
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I believe you need to be completely stock to complete the OTA update. For sure you can not have a custom kernel. If you are fully stock UCKH7 but rooted, that is probably enough to make the OTA update fail.

You have several options. Flash the stock UCKH7 non-root package and then do the OTA update. I know that will work from experience. You could flash the UCKK6 plus root package available from Entropy512 in the Return/Unbrick to stock sticky thread in development. You can just remove device manager and stay on UCKH7. Or, you could decide to install a custom rom.

Many here have avoided the OTA update because the UCKK6 distribution has some problems, the most major of which are the wifi battery drain bug, and that bluetooth hid (mouse, keyboard, etc) does not work.

Edit: I don't know if the unlock interferes with the OTA update process, but that is also possible.
[AT&T Samsung Galaxy S II SGH-I777] drjim:
Thanks to creepy and geo for your quick replies.

My only interest in getting updates is for when ICS arrives (soon apparently). Is that process different? Am I missing anything from these updates?

Creepy, you offered several options. Which do you recommend that is also the easiest and quickest?

I appreciate your wise guidance.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I wouldn't hold my breath for ICS via OTA on our phone soon!

Most here would prefer to get ICS through custom firmware rather than OTA anyway.

But if it does come via OTA, the process should be the same.

As far as what to do, of course your reasoning may be different than mine. My son has an sgsII which he is not into modding. So I installed Entropy512's daily driver kernel on it to get improved battery life and some other benefits. His phone is stock UCKH7 with a custom kernel, so it will not receive the OTA update and will stay on UCHK7, which is my preference for a stock phone. My own phone is running UnNamed with Entropy512's daily driver kernel.
[AT&T Samsung Galaxy S II SGH-I777] melder52:
Entropy's return to stock method is very simple and is what I'd recommend. Although I wouldn't do it until ICS comes out because you really don't want 2.3.6 stock unless you have to (for the reasons CreepynCrawly describes).

Samsung GSII

ICScrewD 2.0.1 (init.doh 0.2.5)

​
[AT&T Samsung Galaxy S II SGH-I777] drjim:
I thought ICS was coming soon to S2. I get it that the periodic updates aren't worth it.

And can you send me a link to Entropy's method?

Many thanks.
[AT&T Samsung Galaxy S II SGH-I777] MWilkenson:
Edit: Disregard.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I believe that the international sgsII, the I9100, will be receiving ICS before long. Even so, if history is any guide, it will still be quite a while after that before AT&T pushes it out to our phone.

A link to Entropy's method? I'm not sure what you mean, but if you want to install Entropy's daily driver kernel onto the stock rom, I would suggest you follow my guide, how to flash custom binaries without incrementing the flash counter. A link is in my signature. You'll need to root your phone using one of the procedures in step 2, and then install the kernel using one of the procedures in step 3.
[AT&T Samsung Galaxy S II SGH-I777] emerica243:
Hey guys, so i followed the instructions and ran the odin one click app. It removed the yellow triangle at boot and did everything swell.

Except the flash counter is still reading 1 count. I bought a jig, and tried holding vol + and - with it in but the phone doesnt turn on. It only turns on when i have my usb cable from the pc in.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Insert the jig while the phone is turned off. Do not hold any buttons. The jig will make the phone boot into download mode.
[AT&T Samsung Galaxy S II SGH-I777] jdedrick:
Creepy:

Thanks for all your work. I wonder if you could put up the UCKK6 equivalents to the UCKH7 stock/stock+root. I just rooted my KK6 phone, (no new ROM, just wanted to freeze the ***king voice talk app that pops up every few seconds.

I lost WiFi and can't complete an OTA update. I understand that a factory wipe might restore WiFi, but don't have any way to back up all the apps etc. I've installed, and it sounds easier just to go back to KK6, and live with the battery life.

Am i on the right track here? Could you put up the KK6 files needed, or point me to them?

Again, thanks for all your work and patience.

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Entropy512 has a UCKK6 plus root package in the Unbrick/Return to Stock thread which is a sticky in the development section. You can flash it with Odin3 v1.8x. However, I'm not sure what side effects you might experience going from UCKK6 to UCKH7 plus root to UCKK6 plus root. I'm also not sure if that will restore your wifi, but I'd have to guess it might. Of course, you'll never know unless you try.

As far as making a one click of the UCKK6 package, I might do that if they start shipping phones with UCKK6, but so far I haven't seen anyone report buying a new phone with UCKK6 loaded.
[AT&T Samsung Galaxy S II SGH-I777] gadget069:
This worked great getting back to stock (Flash the UCKH7-CL503881 stock kernel and system package using Odin3 One-Click Downloader ), i was having some issues that seems to have cleared them up. So right now i'm being a total noob, and yes i did search but the kids are going crazy and cant i concentrate, i cannot seem find how install clockwork mod recovery, i know not to use that app to do it. I know i need a custom kernel, but where and how to install (odin i presume). Again i feel like a tard for asking but im pulling my hair out.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Follow my guide How to Install custom Binaries without incrementing the Flash Counter. It's linked in my signature. Step 2 is rooting. Step 3 is installing a CWM enabled kernel of your choice.

Is there a 2.3.6 version out yet? I rooted it using Odin3 One-Click Downloader Stock I-777 UCKH7 and noticed that the Android version went to 2.3.4 from 2.3.6 and now my WiFi is not working, not sure if it is related but that is the only thing I can do. I have now removed root using odin, but still have 2.3.4 on it. Let me know if there is a version with 2.3.6 or if you have an idea why the WiFi has suddenly stopped working.

Cheers

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Wifi always breaks when you flash back to 2.3.4 from 2.3.6 without a wipe, but a wipe data/factory reset will fix it.

Entropy512 has a UCKK6 stock plus rooted system package available in the Return/Unbrick to stock (or root) thread which is stickied in development.

Why did you post in this thread? This thread is about returning the phone to stock so that you can return it to the store or for warranty replacement.

Any idea what to do if Odin won't recognize your phone?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I assume you have a windows computer. If not, you must use Heimdall instead of Odin.

This would usually be either a driver problem, or a usb connection problem.

First make sure that you have the correct USB drivers for the I777 installed on your computer. You should see "Samsung USB driver for mobile phones" in the "uninstall a program" utility of Windows. It is also possible that you have corrupt drivers installed. In that case, you would need to uninstall the drivers, reboot, and reinstall the driver package.

You should use a usb port that is connected to the mother board of your computer. If a desktop, that usually means use the port on the back of the computer. You must also have a good usb cable, as some don't work. Things you can try: use a different USB port, use a different USB cable, use a different computer.
[AT&T Samsung Galaxy S II SGH-I777] trell959:
Yeah I think it's a driver problem. I'm not new at this either. Odin has always worked for me until yesterday when I soft-bricked. Windows keeps giving me a message saying it cannot recognize this device. Should I use the drivers from Kies or download the USB drivers from Samsung.com?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:

Thanks very much for the guide creepyncrawly. Its really helpful for noob like me.

I am hoping someone can help me to get me back to stock. I got this mobile on ebay it came with unnamed rom and already had the warning triangle. I tried CM9 and had problem with my accelerometer ever since. I was asked to flash back to stock and that should solve my problem. I followed your guide and my custom binary count is 1 and has custom binary. I am not planning to return to store, so do I still have to get a jig and reset before I goto step 2? or can I try step 2 without resetting the counter?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You can leave the flash counter at 1
[AT&T Samsung Galaxy S II SGH-I777] Jive1983:

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If you run the OTA update immediately after flashing back to stock, it should update the phone to UCKK6. I've tested this, but it has been several months ago. I assume the OTA update still works today.

If I were returning my phone in your situation, I would just leave it on UCKH7.
[AT&T Samsung Galaxy S II SGH-I777] artvandalay22222:
Thanks I did just that and it worked. First I tried to return it to at&t warranty center about 10 miles away. They told me since I had bought it less than a month ago, I had to return it to where I bought it. So I took it back to target, and they didn't have any more gs2s but

tiger found a store that did about 10 miles away. Of course the girl there had never done an exchange before, and it literally took her over an hour to do it.

I am back up and running, plus the price is lower and I got the difference of 55 bucks put back on my devout card, so I'm glad I did it
