Losing wifi is a know issue. When you flash back to UCKH7, you have to do a wipe data/factory reset in 3e recovery to get wifi working again.

Kies won't upgrade you from UCKH7. You have to do an OTA update to UCKK6 first, then the kies update to ICS.

Or... you could just flash the stock rooted UCLE5 ICS firmware with Odin from here. Please read the OP thoroughly. You should do a wipe data/factory reset first before you flash the ICS firmware, since it is not recommended to do a wipe with the stock UCLE5 ICS kernel.
[AT&T Samsung Galaxy S II SGH-I777] bailey37821:
Everything went just as you said (almost) I did the reset and got back wifi. I then did an OTAupdate and got uckk6

Kies still says that my version is not able to be updated via kies though.

samsung-sgh-I777

android version 2.3.6

baseband I777UCKK6

Kernel 2.6.35.7

Does anything pop out to you? Is the Kernel correct for Kies? Forgive me, im clueless about this.

@creepyncrawly

I went ahead and flashed to ics via this site and your link.

I read the entire OP carefully. I understand I now need a known safe Kernel?

The phone states this currently

kernel version 3.0.15-I777UCLE5-CL652575

Can you point me in a good direction for a noob? Appreciate all your hard work on this stuff....glad you guys can do it, cause I certainly can't, LOL I would have a drawer FULL of bricks!!
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I have no idea why you can't upgrade through kies. I've never used it myself. So I'm afraid I can't suggest anything there.

Is there some reason you don't want to flash the ICS distribution with Odin? That firmware package is exactly the same as the one that kies puts on your phone, except that superuser.apk and the su binary are packaged into the system partition. If what you want is ICS without root, you can flash that, then use a root file explorer to delete "/system/app/superuser.apk" "/system/bin/su" and "/system/xbin/su'. Reboot and you'll be straight stock, just like you upgraded with kies.

I now see the link to your thoughts on that situation with ucle5, which sounds logical to me. It seems like it is not worth it to change kernels again....but who knows what happened in that isolated incident.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
Even if you never intend to install a custom firmware, there might be some advantage to flashing a custom kernel. Besides the fact that it contains ClockworkMod Recovery, which allows you to customize your phone if you choose, the custom kernel also contains many tweeks and improvements over the stock kernel, which do things like improve battery life, etc.

Everything went well until the innitial phone setup. I get this "Sorry! The application Google Services framework (procecss.com.google.process.gapps.) has stopped unexpectedly.

Bailey,

All phones adapt to certain kernels differently. That being said depending on the ROM you choose, if any, you may need to just try a few out of a couple of days and pick the one that you have the best experiences with.
[AT&T Samsung Galaxy S II SGH-I777] bailey37821:
Sounds good. I actually see that I really dont like ICS all that much and I loose a bit of battery life as well. So I just reverted back to gingerbread uckk6. After all that, LOL but I have already learned a lot so it was worth it. I still want to try a different Kernal though for this stock rom... I did find it odd that the phone did not hold root when I went back. So now I need to root it again first.

Hello,

I got a warranty replacement on my SGH-i777 from AT&T today and it came with the Samsung 4.0.3 version (i777UCLE5, Build IML74K.CLE5) and was wondering if I should flash my phone back to stock (I am running PA 2.14) I took it to the AT&T store and they just got me set up for a warranty replacement because my power button broke *in*. So tell me what you guys think I should do. I got 9 days to send it back or I get a $200 U-OWE-ME from AT&T. :(
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
The one you're sending back should be returned to stock for your peace of mind. I don't think it matters which stock version you use. There's always a chance that they will charge you if you send it back customized.

I also have this problem. However, I am having trouble booting into recovery mode. My phone is plugged in ( and it always thinks it is due to a usb port malfunction). I hold the power and two volume buttons but I immediately see download mode, not recovery mode nor galaxy s2 homescreen. All the button combinations I've tried have resulted in download mode, not recovery mode.

Can anybody help me get into recovery mode? I am very curious as to how trantacular did it, as we had the same initial problem.

edit: other threads show that cleaning the usb port and fixing the usb port malfunction is the solution. I am trying to do this now. The irony is that this is the reason i am trying to return to stock to claim warranty.

solved: unplug your battery. then immediately hold the buttons right after you plug in the battery.

edit: also, the usb problems (phone thinks it's always charging) resolved after recovery. very happy about that!

Wanting to try this on my son's phone. Getting that "voltage too high, charging paused" error that seemed to crop up after rooting and upgrading to this stock ICS :

http://xdaforums.com/showthread.php?t=1650948

I want to go back to stock for him and do a warranty claim as I think there is an issue with his USB port anyway. It's always been finicky. My question is I've read that jig is for 2.3.4 GB or earlier but the phone came with 2.3.6 so would I be able to use the jig, and flash one of entropy512's stock one clicks in ODIN ? Which one would I use 2.3.6 or 2.3.5 ? Just want to get this sucker back to stock and see if it helps this crazy error. Thanks !
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
I am assuming your son's phone is an I777 and not I727? Please make sure before you flash this.

The USB jig will work with the Gingerbread firmwares, and probably with ICS and JB as well. I'm not aware that Samsung introduced any modified bootloaders with any official release, and the developers usually don't include bootloaders, so the phone should have the original bootloader, which will allow a jig to reset the counter.

I'm not aware of a 2.3.6 stock firmware. To get 2.3.6, you could flash Entropy512's UCKK6 plus root package and then use a root file explorer to remove root manually. Or you could just flash the UCKH7 2.3.4 stock firmware. I don't think it really matters for warranty. BTW, there was never a 2.3.5 for the I777.
[AT&T Samsung Galaxy S II SGH-I777] hednik:
Yes its a i777. The i727 is the skyrocket, wife has that one. I guess I was mixed up on the 2.3.5 because some of the flash to stock posts said to flash 2.3.5 or 2.3 6.

All the sites for USB jigs like mobile tech videos say they only work on 2.3.4 but I assume we all still use GB boot loaders. I'm actually wanting to flash back to stock and clear flash counter and root with mobile Odin so I don't trip the counter and get him on SHOstock. This phone just scares me because of the greater possibility of a brick compared to my cappy.

So I clear the flash counter, then flash entropy512's uckk6 and remove root manually with root explorer and then follow the walkthrough from creepycrawly to root again ? Its seems odd to flash ROM's in mobile Odin but I guess it works.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
No. You said "I want to go back to stock and do a warranty claim." For that, you would need to remove root, or flash pure stock. (And this is the warranty guide.)

If you want to wind up with ShoStock then it doesn't matter which stock plus root package you flash. But keep the root and continue on with the guide. (Not this giude, but the first one in the sig below.)
[AT&T Samsung Galaxy S II SGH-I777] hednik:
I'm sorry for me flip flopping on what I want to do. It hard to say if a warranty is the route I want to do because I'm not sure what caused the "voltage to high" error. It could be caused from so many things and I'm unsure if going back to stock will fix it or if its an actual hardware issue. This walkthrough seemed like a great place to start to help me get his phone back to factory specs if its what I really need to do. I've flashed your one click before to root his phone and it worked perfectly. Just worried to flash anything with his error he gets and the phone being finicky as I don't want to brick it. Also wondering if the flash counter is all they would check ? Basically if it says zero flashes and I followed your walkthrough is there Anything else they check to see.

I am trying to fix my nieces bricked stock phone. I could not get it into recovery and had to use jig to get into download. Using Oden3 v1.85 I get to NAND write start!! and it hangs. Any ideas?
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
It's hard to say what might be going on without more information. What package did you use with Odin? Also, describe the problem with the phone. What caused the problem in the first place, and what steps have been taken so far? Provide as much information as possible.

Okay here is what I know. She said before it went down things got real slow, when she gave it to me I could not get it into recovery mode and I had to use my jig to get it into dl mode.I first tried Kernel + cache + rooted UCKK6 system package: http://dev-host.org/8LA and it would start and then hang no mater how long I let it go. I then tried the UCKH7-CL503881 with Oden3 v1.85 I get to NAND write start!! and it hangs. I also tried to add the 512 PIT file with no change. Is it possible the internal memory is bad?

Boot loop after step 4

I followed all your steps and the package completed successfully. It went into a boot loop so I followed step 4 and went into recovery and did a factory data wipe. It went into a boot loop again so I am trying to enter recovery again and when I do I get the following message:

Deleting Cryption Meta data.

After that message it enters a boot loop again. Even while hold all thre buttons. Any ideas?

Do I need to install a driver to get Odin to talk to the phone?

Prepare Your Phone to Return to the Store or for Warranty Replacement by following these steps:

1. Read the flash counter to make sure your flash count is at "NO". If it reads "YES (x counts)" then you must buy or build a Jig to reset it to "NO"...

...or use chainfire's "Triangle Away" program (which only work on ICS, Android 4.x)

2. Flash the UCKH7-CL503881 stock kernel and system package using Odin or Heimdall.

3. Deal with any special problems.

4. Do a wipe data/factory reset, and remove any personal or sensitive information that remains on the phone.

Thanks for this note. I am trying to reset this device to give to someone else.

I followed the instructions exactly as above. My custom binary download showed NO in step 1) so I went ahead and followed 2a.) Flash the UCKH7-CL503881 stock kernel. After downloading and starting Odin, I plugged in the phone holding down the vol up and down buttons and then pressed vol up to go into download mode. However, the small edit box in the upper left corner of Odin never turne yellow, and didn't display anything. It seems like some communications driver is required for Odin to talk on the USB cable. This is a new laptop. Abandoning the download and restarting the phone worked fine.

What should I do to proceed?

Step 4 - 3e Recovery still not available

I am running an I777 that was stock with Official AT&T ICS (even flashed AT an official device repair center). The phone would occasionally hang so I would just reboot, finally yday it would not boot past the "SAMSUNG Galaxy S2" open screen. Hard reset wouldn't work. All I could do is enter Odin DL mode by holding "-vol & pwr."

Finally gave up and after much reading, tried to flash some Siyah Kernels as phone is out of warranty. Odin3 said they uploaded, yellow turned green and confirmed successful 1, still no luck booting or accessing 3e Recovery. Flashed back to Samsung official "I777UCLE5_I777ATTLE5_I777UCLE5_HOME.tar.md5". Odin mode always reported Custom Binary DL as NO. After more reading I found this thread and I followed 2A, with confirmed success. Still no reboot and still no 3e recovery option. I can flash through to the second intro screen but it simply hangs there.

I have tried every variation of plugged into USB with and without battery, key combos, the works. Nothing gets me past the "SAMSUNG Galaxy S2" intro screen unless I boot to Odin DL mode. Help!?! -Thanks bykviki'noob"g
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
First thought is memory damage. However, I am puzzled by your quote:

The button sequence for entering download mode is to hold vol- and vol+ but not power while plugging in the usb cable. If I remember correctly, vol- and power is the button sequence for the international version.

The correct button sequence on the I777 for entering recovery is to hold down all three buttons, vol- vol+ and power, continuously until it boots into recovery. If it doesn't boot into recovery after the first splash screen, then continue holding down the three buttons and let the screen go black and the splash screen appear a second time. If this gets you into recovery, perform a wipe data/factory reset and see if it boots up ok.

In any case, let us know your results.
[AT&T Samsung Galaxy S II SGH-I777] bykviking:
The confusing quote is exactly right, I was able to enter download mode by just holding VOL- and long pressing and releasing PWR. Maybe I was also pressing VOL+ unknowingly, but I did it

numerous

times. I bought the phone October 2011 in an Escondido AT&T store. Either way, I mostly have been entering download mode using the VOL+&VOL- plus USB since I learned that trick, more consistent results.

Regarding entering recovery, I'm trying again now... and this time it didn't even go past the first splash screen. Trying once more... went to second splash but still no dice, hung. You said memory issue, am I S.O.L. or is that addressable?

Thanks for the quick reply btw.
[AT&T Samsung Galaxy S II SGH-I777] creepyncrawly:
If it is damaged memory, then there is probably no way to recover. Let's hope that is not the issue. What made me think of that is that the phone was stock ICS with the stock ICS kernel, which many here think is still possibly susceptible to the eMMC superbrick bug. You can do some reading here if your're not familiar with it.

I am aware that holding vol- and power will boot to download mode when the battery is removed, and the phone is powered by the usb cable. But until now I haven't seen that reported to work while the battery is in.

What puzzles me is that, if I read your post correctly, all the odin flashes finished and reported success. If there were memory issues, I'm not certain that the odin flashes would complete successfully. The problem could be a corrupt bootloader or param file. I certainly would not give up on trying to recover the phone yet. You might try flashing secondary bootloader or param.lfs or both. You can find them in the download repository. (See my signature.)

As a final resort, you could send it to Mobile Tech Videos for a jtag repair. I think that costs $50 or $60 or something. If it actually has eMMC memory damage, then they can tell you that also. If it was me, I'd call them first before sending the phone there.
[AT&T Samsung Galaxy S II SGH-I777] bykviking:
Awesome thanks, I'll check these out, but first I'm going to go visit the Service Center tomorrow and hopefully see the same guy I saw both times before. He was suspicious that it could be hardware causing my freezes but reassured me both times that it was likely app related. (Even though it froze once immediately after he re-flashed it as I was shaking his hand walking out the door!!) So maybe he'll take pity on me as I did reach out twice before my warranty was up. I'm just hoping flashing the original profile doesn't cause him to question what I've been up to, but based on the experience so far I suspect it might not have even taken despite the positive result. I'll also just tell him that once it was down I only saw your post and simply tried to flash back to factory settings. (BTW don't know if it matters but I realized I left it out of my original details, Kies does tell me that I am running 4.0.3 according to my S/N.)

I'll report back what goes down because if he sends me packing I'll try the bootloader /param.lfs route. Even more jargon deciphering... yay.
[AT&T Samsung Galaxy S II SGH-I777] John822:

I had no trouble returning my phone root and all
[AT&T Samsung Galaxy S II SGH-I777] bykviking:
Update - Service Center manager lady was nice and sympathetic but was also surprised that phone wouldn't reboot even though her flash reported success. Told me that because I was out of warranty but did have insurance that her hands were tied and I would just need to replace it via my own means. I pleaded for her to pull some strings, no dice, her suggestion go get an S3, slightly better than the HTC One X. I can replace the S2 via insurance for $200, but don't have an upgrade available yet so an S3 would be $450. Retail store jacknapes offered me an early upgrade if I bought a bluetooth Jambox and some other BS accessories for an extra $100 or something. Wouldn't budge otherwise.

Just flashed the bootloader and param.lfs files from your repository, both reported success but still no reboot or 3e recovery... guess I might need to call the folks you suggested unless there are any more suggestions. I also thought it was odd that the bootloader file was suggested to be flashed via PDA and not the bootloader option. This isn't the forum to tell me why, but if you think I should use the sbl.tar with the bootloader option and the param.lfs in the PDA I can try that too.

Any other ideas?
[AT&T Samsung Galaxy S II SGH-I777] bykviking:
Final Update: Talked w/ Josh at Mobile Tech Videos. He said it was likely the eMMC, but that I might be able to repartition it as they don't yet offer eMMC replacement service yet. Suggested I look for the Galaxy Note N700 8.25gig PIT file. I searched around for a bit, but couldn't track it down. When I finally called the insurance company they actually upgraded me to the S3 for the same $200 it should have cost in the store... but it required I send my S2 back, so I never got to try and flash a PIT file. Oh well. The S3 is quite nice, just BIG. Thanks for all the help.

followed directions and still won't boot

History:

Yesterday I set my phone down on the desk and then went to do some things. Came back and the Galaxy SII logo was flashing. I took the battery out put it back in and same problem. I then tried to go to recovery and could not get in. I then followed the directions that you have posted here to go back to stock and again have flashing logo. I followed step for in your guide. Looked like some things were loading and I got excited then flashing logo again. I tried to get into 3e recovery again and get a message saying deleting cyrption meta box (I think, it goes away really fast) and then back to flashing logo.

I have a SGH-I777 from AT&T and would really like to get this running again.

I am hoping my phone is not completely hosed. Please help!

Thanks!
