When I did my flashing I didn't do anything with the modem slot that entropy mentioned was in a different download and needed to go into the phone slot on Odin.

Since then I have flashed two Roms, both which have cellular signal but no data signal. Is this related to me not flashing anything with modem when I returned to stock/unbricked?

Once I get to a computer outside of my work network I'll just download your odin/firmware file you posted. The UCKH7 I believe it is. I flashed entropys "Kernel + cache + rooted UCKK6 system package: http://dev-host.org/8LA" but I couldn't find the UCKK6 modem package. I did find the UCKH7 modem and tried flashing that along with "Kernel + cache + rooted UCKK6 system package: http://dev-host.org/8LA" with the system package in the PDA slot and the modem package in the Phone slot but I still have no data signal.

I'm downloading "The kernel + rooted UCKH7 system package is here: http://dev-host.org/UWm" to try and flash with the UCKH7 modem package I already have downloaded.
[AT&T Samsung Galaxy S II SGH-I777] butikofer08:
Any Idea why I would get a black screen after a successful flash in Odin? I do have auto reboot enabled and I've tried two different downloads of two different firmwares with no luck. I am able to get into recovery and wipe data but after rebooting in recovery, still just a blank screen.

I just tried again in Odin and it again passed. I'll let it sit on this blank screen for 5-10 mins, maybe I'm just not waiting long enough but It didn't take this long last time.

Here's the txt in the dialogue box after my successful flash:

I'm thinking bad hardware because I can literally feel my phone getting hot. I'm pulling the battery after 15 mins of a black screen with nothing else. Oh yeah...and suddenly recovery is not available. Download mode only.
[AT&T Samsung Galaxy S II SGH-I777] cattledog:
Thanks for the information in this thread.

I really disliked the AT&T 4.0.3 release. I was able to go back to 2.3.4. I will be staying wit 2.3.4 unless I get a better understanding of ROMs and install of CWM. It's only a matter of time.

Thanks!
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I can't remember having seen this type of thing reported. The only thing that comes to mind is that your readout says "Odin v.3 engine" so I assume you're using one of the latest version of Odin, v 3.05 or .06 or .07? I know this version of Odin is recommended for the SGS III, but I don't have any knowledge of it's use on our phone. From what little reading I have done, I think it's supposed to be interchangable, but I'm not sure about that.
[AT&T Samsung Galaxy S II SGH-I777] stalked_r/t:
I am selling my s2 since I now have the Verizon S3 (don't ask...). my problem is that I'm coming from CM9 6/29 nightly with it's built in kernelt etc... I downloaded the one touch file and ran it. Problem is that 4 hours later the status bar hadn't moved and nothing seemed to be happening. So I unplugged it and rebooted my machine. Now my phone says "firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". I tried Kies for the hell of it and got nowhere. It sees the phone, but can't connect. Windows Sees the phone as well. Odin every time I start it, it does the same thing. After the first attempt I only let it go for an hour before figuring something was up. I'm redownloading the stock file again in case it was a corrupt download. Anyone ever had to deal with this and have some advice?
[AT&T Samsung Galaxy S II SGH-I777] bdpyo:
Returned to stock yesterday and had a question.

I don't remember my colors being this way;

I was originally on uckh6 before I gained root access and started flashing custom ROMs.

Everything else is working great, this seems to be my only issue..

Right thread this time.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
There is no UCKK6 stock to flash back to. The only way to obtain fully stock UCKK6 is to flash Entropy512's UCKK6 stock plus root, and then delete superuser.apk, the su binary, and busybox.

So returning to stock on Gingerbread means UCKH7, which was the original distribution for this phone.

I don't remember the color of the background in messaging in UCKH7 but maybe it was different than UCKK6?
[AT&T Samsung Galaxy S II SGH-I777] bdpyo:
Thanks for the reply but what I was saying is that when I bought the phone it was loaded with uckk6 then unfortunately used a galaxys2root method which broke wifi but I straightened that out.

Flashed a few roms then used this method to come back to "stock", boot looped then wiped everything as suggested. The original colors were black and I just wanted to know if the white was correct for uckh7?
[AT&T Samsung Galaxy S II SGH-I777] Hyp3rdr1v3:
Need to send my phone to Samsung for service so i tried the odin one click return to stock, got what appeared about to be about 75% through when i got a Fail! and "firmware upgrade encountered an issue" please try kies bla bla.. I was running Task's AOKP and the kernel packaged with it, which allowed me to successfully use TriangleAway to reset the flash counter.I had flashed that UCKH7 modem I believe, could that be an issue?

Any subsequent attempt through Odin returns an immediate fail as well as:

Any help? I'm not sure what to do from here
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
OK. It seems there is always AOKP in the mix somewhere, and I don't know that firmware at all well, but it seems to make some changes that are hard to fix sometimes.

Can you get into recovery mode at this point? You may still be able to depending on what has happened during the various Odin flashes. Try that and let me know, and if so what recovery do you have?
[AT&T Samsung Galaxy S II SGH-I777] Hyp3rdr1v3:
CWM, but I can't get to it the only screen the phone goes to on boot is the same one telling me theres a firmware upgrade problem and to use Kies. Scale of 1 to 10 how SOL am I.. haha
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
You should be able to recover the phone.

What is the issue that makes you need to return the phone for service?
[AT&T Samsung Galaxy S II SGH-I777] Hyp3rdr1v3:
It acts like the power button is jammed, i.e. the button neither wakes or turns the screen off and the phone reboots almost constantly. I know this sounds like a bad flash or something but I've been flashing aokp since like february with no problem, and hadn't even flashed anything new for several days once it started (about a week ago.)

It doesn't physically feel any different when it's clicked (the power button that is) but any single press results in the phone acting as if the button is being pressed and held. For the sake of doing the return to stock I took the housing off and removed the power button so as to allow it to actually go to download mode without booting.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
It could be as simple as the cable, or the usb port. Use the original cable that came with the phone. Use a usb port that is directly connected to the mother board.

Look at this thread. I gave the same advice in post #4. And then look at post #28.

How can I fix this?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Do you have SGH-I777, or is it some other model?

I can see from the above that Odin sees the phone but the firmware does not complete. Flashing the stock UCKH7 one-click downloader onto a working SGH-I777 will not fail, so we need to know all the particulars about your device, what exactly has been done to it, how it was behaving, the reason you need to flash back to stock, if there are any known hardware problems, etc. Tell everything you know about the phone.
[AT&T Samsung Galaxy S II SGH-I777] mr. mustache:
I attempted to install an insecure kernel to the phone, and got the same message from odin. The kernel was supposedly the one for my phones make and model (SGH-I777), and it gave me the same error message. Every other kernel has done the same.

the phones current behavior is that it just hangs at "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again"
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Exactly what kernel, and downloaded from where. A link to the source would be helpful, if possible.

What a lifesaver!

I don't know what's the problem, but this wasn't my first update from AT&T to be riddled with issues.

I had the Moto Atrix2 for a couple of months and during that time AT&T pushed out an update that made the device useless (for my needs). The deal breaker for me was that Wifi and data connectivity was unstable and apps would disappear. Following instructions from here I was able to revert the unit to stock, but there were still issues. Other forums also reported that the OG Atrix had many of the same symptoms from the same update. That unit went right back to Costco and I got the SGS2 instead.

I was extremely pleased with having SGS2, up until the ICS update (well, at least a little less than when it was stock). I'd get random reboots (while it was in my pocket, I'd know because I'd hear the AT&T startup tones while driving or walking), Wifi would sometimes disconnect from my home AP overnight, touch sensitivity from the lock screen didn't always recognize that I never lifted my finger off the screen if I didn't swipe fast enough (I learned to deal with that), sliding wallpaper was gone (oh well), Google Voice widget was lopped in half (eh), predictive text from any input method was flaky (sometimes I'd get a black row where the suggestions were suppose to show - dealt with it by forcing a selection change in input method when this symptom cropped up), and battery drain went up (dammit). It wasn't all bad, ICS has many other improvements , but its always the little things that can get on your nerves.

Anyway, thanks to you guys, my SGS2 is back to stock and I'm once again, a happy camper! The one click solution, doesn't get any easier!
[AT&T Samsung Galaxy S II SGH-I777] mcvigo:
IM getting this, an idiot flashed a 9100 rom onto this and what I did was take the xxlpb firmware he flashed onto it, flash a kernel with cwm and then flash a i777 rom worked but the rom just randomly reboots.

Dunno what to do considering this package always fails after cache.img.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Try the full firmware version which you can get from the download repository. See link in my signature. The I9100 firmware may have contained bootloaders and needs to be put back.
[AT&T Samsung Galaxy S II SGH-I777] mcvigo:
Flashed the bootloader and stock param lfs and the phone entered the shostock right away.

The issue that it randomly turned off and wouldn't boot into the rom again seems to be fixed.
[AT&T Samsung Galaxy S II SGH-I777] Baldomero13:
Hi there! I rooted my brother's phone without knowing it takes so much work to unroot it compared to rooting it. He wants to return it because he told me the phone gets very hot randomly on his pocket without really running anything. Thank you for writing this guide! I'm a noob with all these stuff :(

Anyways, about the phone:

Model Number: Samsung-SGH-I777

Android Version: 2.3.6

Baseband Version: I1777UCKK6

Kernel Version: 2.6.35.7

Build Number: GINGERBREAD.UCKK6

I did the checking thing and turns out my CUSTOMARY BINARY DOWNLOAD says YES 1 COUNT. Now, I don't know which JIG is needed for me? I checked amazon and got these:

http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=micro+usb+jig

Are any of these the right one?

I was looking at this in particular

http://www.amazon.com/Aftermarket-Download-GT-i9100-Fascinate-Replacement/dp/B005UUCT0Y/ref=sr_1_2?ie=UTF8&qid=1344273648&sr=8-2&keywords=micro+usb+jig

How would I use this Micro USB Jig? Just plug it I'm guessing?

ALSO, on your NOTE, you said that if you have UCKK6, you need to flash UCKH7, this phone needs to have USB debugging checked right?

I just want to get everything right on my first try, and have read the entire post twice.

Again, THANK YOU FOR MAKING THIS GUIDE :)
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Those jigs will probably all work ok. The resistance must be 201,000 ohms plus or minus 1%. If out of tolerance it won't work. But I havn't heard anything about out of tolerance jigs in many months.

Yes, just plug it into the micro usb port, it will boot into download mode, and the flash count will be reset.

Whether USB debugging is checked or not is irrelevant. You will be flashing with Odin from download mode. Just flash the stock UCKH7. There is no straight stock package for UCKK6 since it was an over the air update instead of a kies update. But it should be fine for returning the phone.

Are we supposed to be sending it back with 2.3.6 or run Kies to get it up to ICS?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
There is no 2.3.6 stock, unless you can get the over the air update to work. The choices are either 2.3.4 or ICS. You can find UCLE5 stock ICS in the Download Repository if you don't want to fool with kies.
[AT&T Samsung Galaxy S II SGH-I777] qwertyaas:
For some reason I thought stock was 2.3.6. Been a while since I have been there :p

I'll probably go GB since I have that Odin downloaded already.

From reading this, it sounds like I am screwed cause my USB port is cooked? I'm guessing there is no way back to stock just using CWM, huh?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Assuming you're rooted, install Mobile Odin (pro or lite version) and you can flash back to stock with it. I think there is even a guide around here somewhere on how to do it.

[AT&T Samsung Galaxy S II SGH-I777] SteveO390:
Creepy,

Please forgive my noob question but I would like to know how to get back to ICS after having used your extremely helpful guide to flashing the UCKH7 firmware.

To give you a quick background on my situation, I purchased my phone new a couple months ago, got it on my lunch break, had it for roughly 5 hours, came home and updated to ICS using Kies. A few days later I rooted it by flashing Siyah 3.4.2 and figured out how to use CWM and flashed up to Siyah 4.1.1 a few days ago. I discovered that hulu+ and Crackle wouldn't play videos so this morning I decided to make a nandroid back up and do a factory reset to try and "start over".......which bricked my phone. That's when your guide was brought to my attention and I now have a functioning phone again (THANK YOU for that!!) but Kies tells my that I'm already on the latest firmware. Do I need to flash the UCLE5 firmware as you describe in detail here http://xdaforums.com/showthread.php?t=1746181 in order get ICS back on my phone? Is that the only way I can do it?

I would also like to say that aside from the issue I was having with those two specific apps every Siyah kernel I used worked just fine and since using your method to get my phone up and running again Crackle still doesn't work quite right, it just plays sound as if the video is playing but no actual video. I've come to realize that for how little I use hulu+ and Crackle all this wasn't worth it and I'd actually be happy to get my phone back to stock ICS with Siyah and CWM on it again.

Any and all advice would be greatly appreciated. I also read your opinion linked near the start of the thread and it sounds like the risk of the eMMC error is minimal so I'm willing to give it a go.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I'm not familiar with Hulu+ and Crackle so I can't answer about that. I usually don't watch movies on my phone, except for netflix.

If you want stock ICS UCLE5, use the stock plus root available in the development section. That will include the stock kernel, just like Kies would, except it's pre rooted. Then flash your siyah kernel, or whatever custom kernel you want.
[AT&T Samsung Galaxy S II SGH-I777] SteveO390:
In the interest of trying to do my small part to contribute and give thanks when it's due I'd like to report that I was able to flash the UCLE5 without a hitch and want to thank you once again creepyncrawly for your comprehensive and easy to follow guide. I then installed Hulu+ and Crackle to test their function on the stock ICS firmware and kernel and I was getting the exact same errors as I was getting when I was using the Siyah kernels.

I have now got my phone back to exactly where it was (with the exception of the flash counter which is now up to like 8 I think) and it is all because of the two completely thorough sets of instructions by creepyncrawly! Thank you one more time sir.
[AT&T Samsung Galaxy S II SGH-I777] notnowme01:

Hi there

Firstly, big thanks to creepyncrawly for all the help on this thread. I've used the guide to restore my phone to stock a number of times successfully.

This time however Odin keeps hanging during the process. The green bar gets to around 7% and just stays there flashing.

The message I get is:

<ID:0/068> Added!!

<ID:0/068> Odin v.3 engine (ID:68)..

<ID:0/068> File analysis..

I've tried this a number of times and have even tried switching usb ports but to no avail. (screenie attached)

**Also, msg displayed on my phone now is "Firmware upgrade encourntered an issue. Please select recovery mode in Kies& try again.

Any help with the above would be greatly appreciated. Thanks.

[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
@Gurumi,

Can't really say much without knowing what the state of the phone before you tried to flash back to stock. What was the issue that makes you want to flash stock? What firmware was installed? etc.
[AT&T Samsung Galaxy S II SGH-I777] Gurumi:
Thanks. I was on AOKP (ICS and had been on this for 2 months) and was charging my battery when my phone suddenly died. I tried powering on but the phone would always freeze during boot-animation. I tried booting into recovery to perform a NAND backup but encountered an error -> something about unable to back-up data. I tried rebooting into recovery again but CWM would would come up blank i.e. no options to scroll through.

After all of the above I tried to reflash stock with Odin and haven't had much luck.

This morning I tried performing an Emergency Recovery through Kies as well as another round through Odin and now my phone is bricked :( :(

I haven't tried getting into download mode with the battery out (will do when I get home) so not too sure how bricked my beloved phone is :(
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Also try a usb jig if you have access to one.

You can't do anything unless you can get it into download mode. Even then, I'm not sure what to suggest. Obviously flashing the stock isn't working. Maybe the full stock with param.lfs and secondary bootloader from the Download Repository might flash through. Worth a try. I assume you're flashing 2.3.4 stock. After that, you could maybe try flashing full stock with repartition checked and the pit file from the Download Repository in the pit slot (using Odin, not the one-click downloader).
[AT&T Samsung Galaxy S II SGH-I777] mrgoat:
I just flashed my phone with the one click installer and everything went okay. However now it boot Loops and when I try to do a factory reset it asks for a password. I have no idea what password it wants
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Each time it asks for a password, leave the password field blank and accept the prompt. Repeat the process 4 or 5 times, and it will bypass the password and complete the factory reset.

wi/fi after I777UCKH7-CL503881-No-BL

Thanks for all the hard work on the odin one step, but I had a problem.

I just rec. the phone (sgh i777) from ebay that looked completely stock and running uckh6. Kies told me not eligable for update though and so I flashed to I777UCKH7-CL503881-No-BL via odin one step figuring that the stock kernal had been modified someway and needing to get to the point that Kies would give me the official ICS.

Everything went smoothly on flashing and the phone operates great except that the wifi is no longer working. It will turn on and scan but then turns itself off.

Also Kies no longer gives me the message that I cant upgrade...it now states that I have the latest firmware, LOL. I would really like to get the official ICS release on this thing, but at the very least I need to get wifi back.

Any help would be greatly appreciated.......
