I have attempted to flash the recovery partition and modem partition. It fails in Odin and returns the following error in Heimdall:

Uploading MODEM

100%

ERROR: Failed to confirm end of file transfer sequence!

MODEM upload failed!

Ending session...

ERROR: Failed to send end session packet!

I have tried multiple times. You also cannot flash sbl, boot, recovery or datafs without getting the same errors. You can successfully flash factoryfs, cache, hidden and kernel. There are several more here that can vouch the same thing. When did I ever post that I succeeded in flashing the modem? I do not recall ever posting that, the baseband has never changed on my device.

Since my phone is hosed as of right now (wont boot beyond Rethink Possible regardless of what I flash) I went on ahead and attempted to flash the modem partition with your dailydriver Entropy. Here is the outcome of that little experiment:

I have been watching this for a few days now and just signed up so i can post. Loved the Noob video btw LOL.....I still have an unmolested S959G if you guys need anything to keep this project moving. I AM a noob when it comes to smart phones, but i am proficient with PC building and tinkering. Whatever i can do to help.....

EDIT: Just heading to work and will check back in about 12hrs....
[AT&T Samsung Galaxy S II SGH-I777] mr-cook:
Entropy512 thank you so much for jumping back in here, and giving us a direction to head in. Hopefully you stick around to see the progress. Cynnar and eclipsedarkmoon didn't you already dump all the partitions? Now that we know the count numbers were off, could you please attach the correct ones needed? Then hopefully someone will be able to build a working kernel. With the info entropy512 has given us we are very close to getting this.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Those look like an Odin protocol mismatch and not a sign of locking to me. I'll ask AdamOutler for details on what it looks like with a locked down device, but that REALLY looks like what happens when you have a protocol mismatch with broken PIT handling. I've seen the EXACT same thing from devices that I KNEW were unlocked when using the wrong version of Heimdall or Odin.

I covered it earlier, but the most important ones are for someone who has only flashed Daily Driver (not Siyah as that touches /system, although for some purposes it's better than no system dump) to get mmcblk0p6 (recovery) and mmcblk0p9 (system) dumps. Also a modem partition dump (mmcblk0p8) would be a good thing to have. Param (mmcblk0p4) is less important but still useful.
[AT&T Samsung Galaxy S II SGH-I777] graphicw:
That could be possible. Both Heimdall and Odin fail on the boot, sbl, modem, datafs and recovery partitions. You can only flash kernel, hidden, cache, factoryfs and param partitions. You can also change the PIT as well. I have already tested that since my phone was hosed anyway. Thanks for looking into it. Should we find that partitions are indeed locked, how would we work around that?
[AT&T Samsung Galaxy S II SGH-I777] Jack_R1:
Here's the best reason to believe there's no lock on partitions:

One of the "supposedly locked" partitions is datafs, which is userdata and writable by default. There is absolutely no way to work with the phone if this partition is locked for write. Given that, I believe other partitions aren't locked either.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Yeah. Datafs fails when flashing with Odin/Heimdall on a regular basis. Hell I don't think I've ever succeeded with that.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Even if Odin can't flash a partition, you can flash it with root access. The only exception is mmcblk0boot0/1 (needs a kernel patch) and HTC devices (that S-ON ****) - I've never seen a standard MMC partition write-locked on any Samsung I've ever worked with.

DO NOT try to **** with boot/sbl - improperly flashing these can easily hardbrick you.

Which version of Heimdall was it? 1.3.2 had a lot of issues on Samsungs.
[AT&T Samsung Galaxy S II SGH-I777] graphicw:
I tried Heimdall 1.31 as well and had the same issues. I only tested to see what partitions could actually be flashed which is why I attempted to flash datafs. My phone is pretty much hard bricked as of right now anyway. I will be able to be the guinea pig when a solution is found because I have nothing to lose by flashing the phone.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I know even 1.3.1 had issues with datafs.
[AT&T Samsung Galaxy S II SGH-I777] graphicw:
I decided to experiment with Heimdall 1.30 and it ends up the same result as 1.32 and 1.31. I will say that Heimdall 1.32 cannot flash cache or factoryfs without failing whereas Heimdall 1.30 and 1.31 can.
[AT&T Samsung Galaxy S II SGH-I777] Edward12:
I have a unmodified sgh-s959g, and I'd be willing to help in any way, as long as reverting back to stock is possible. Don't know much about Android (but am familiar with Linux on PC). If I understand correctly, if someone with a custom kernel uploads a dump of a pre-rooted filesystem, I could copy the image to my phone, and dump the stock kernel? There's no way to access the kernel image from outside the phone?
[AT&T Samsung Galaxy S II SGH-I777] StoneComputers:
You Guys are the best!!!

Reading this thread is like reading an intense book with ups and downs my heart really sunk when the guy said it was locked and the others quit... I had my phone in its box ready to return then the other guy posted (I'm sorry I'm horrible with names) he started talking about how it cant be locked and then others started to go along with him and my phone was back out of the box and back in my pocket... I really love this phone and I hope this happens...

Those of you who have flashed to the AT&T firmware are you using the SIM card that came with the phone? and those of you who flashed it and then messed it up were its now showing its the i777 does it still work on the network? At first when I brought the phone home I tried to use my BYOP SIM and the voice and text worked but not the Data and MMS I looked at the APN settings and they are the same as the ones I used on my iPhone, but there are a few more... I really want to root my phone because I need tethering (if any of you know of a tethering program that works without root on this phone with this network could you let me know?) also I want to edit the APN settings because I saw in another post on here that if you get rid of the proxy they cant keep track of your DATA usage or throttle your speed (anybody else do this?) I am a very patent man and I can wait for a proper root since I've seen people have complications with the AT&T ROOT so Im waiting a little while to see how you guys do... I know this post is a little off course but mainly Id like to thank you guys who do all this work and you do it just for the thrill and the cred... I tried so many times to get into the programing part of Tech but never got a hang of it... even though I used to run DOS back in the day and can still remember most of the commands (I hear Linux is close to old DOS with its commands) Im a hardware Tech and do a lot of repairs.

If nothing comes of this after a while I guess Ill try that Odin AT&T root but I have faith you guys will bump this thing out... ROCK on my friends

We are still not out of the woods yet as far as getting a solution for this phone and there are still several things to look into. If it has not been 15 days since you bought it yet, you may want to look into taking it back. As some have already pointed out in this thread, there are phones out there with better hardware available at the same price that already have custom solutions available for them. I have cofidence that there may be a solution for this phone eventually, but it may still be a bit of a wait on that.
[AT&T Samsung Galaxy S II SGH-I777] SkywolfNINE:
so are there any roms i can flash with odin to get this thing to use wifi so i can add a APN? ive tried the zedomax kernel and that kills wifi, the siyah kernel just gives me a blank screen, and anything else i find wont show up in odin. my phone is stock other than those 2 flashes so i may be of help as a guinea pig, although i am just learning how to do all of this. i work for walmart though so i can get my hands on the returned phones before we send them to claims and test them if needed
[AT&T Samsung Galaxy S II SGH-I777] eclipsedarkmoon:
greetings all. I am still actively working on stock recovery and getting clockworkmod working on this phone, albiet at a slow pace. I am juggling a lot of different things at the moment.

My dualboot laptop with ubuntu decided that it wants to randomly shut down, so it has been deemed unreliable for testing with the phone and I am working on getting ubuntu installed on a different computer.

I do not have a virgin dump of mmcblk0p9 the factoryfs.img and would like someone who has to upload it and provide a link. I am going to work on building the odin flashable tar with a rooted factoryfs.img, so then someone should be able to get a stock rom. Once the stock rom is avail, a stock rom should be able to be built.

graphicw, since you are currently bricked, would you try flashing a i777 stock rom, either gingerbread or ICS, perhaps if that will take the phone can be exploited to a clockwork recovery.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
That's the biggest thing we need.

Although I just realized - Most likely, one of the prerooted I777 system images would work for getting a stock kernel dump.

So if one person:

Flashes a prerooted I777 Gingerbread image (UCKH7 or UCKK6, doesn't matter) in Odin/Heimdall, they can get stock kernel (mmcblk0p5) and recovery (mmcblk0p6) dumps

If another person:

Flashes a Gingerbread Daily Driver release and NOTHING else, they can get stock system image (mmcblk0p9) and another copy of stock recovery (mmcblk0p6) to be sure we have a good dump of it

Once we have a backup of stock recovery, and ONLY after we do, then someone can see if flashing DD to mmcblk0p6 changes the recovery behaviors.
[AT&T Samsung Galaxy S II SGH-I777] StoneComputers:
Conspiracy theory....

I usually I have no problem waiting, in fact I think the way it sits is really fast and minimal, Also I can not return the phone... if I did I couldn't buy a new one since I used my Walmart credit card to get it... but the problem is whats going on behind the scenes. Have any of you guys installed Avast antiVirus on this phone yet? When installing the theft system Avast wants to install a program to get all incoming text before they are posted on the phone (so you can send commands to the phone to lock it, erase it, and stop it from shutting down so you can find it on the map and do what must be done to get your phone back.) There is a problem when they try to install this and its Trackfone Device Manager it takes first look on all your incoming Texts and data... Can ANYBODY tell me what this does? is Tracfone receiving my incoming texts? do they have a system laid out to control my phone just like this Avast program can do, by sending my phone texts and doing things like changing my settings and other things? This is one reason I cant wait to ROOT the phone to get rid of this crapware and I hope if this program does in fact spy on us we could sue or press charges... I am sorry for posting this here but this thread is the top thread for this phone thus far and those of you on the net that could check this thing out are here already... Anybody know what this thing does when it intercepts text messages? what else does it intercept? I wonder if the phone could be unlocked or controlled by this... maybe Im just paranoid but its worth taking a look at...
[AT&T Samsung Galaxy S II SGH-I777] RBarnett09:
You may as well check it out. It definitely won't hurt anything. Just make a backup just in case you want to revert. Let me know how it is. I'd probably have it on the S2 if it actually belonged to me. I guess I could have said my mom now has a rooted S2 in my past post. Ha.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
CM9 for the SII doesn't have some of the bad things that are present in CM10.x, such as the memory leaks.

My son recently went back to CM9 and my old ICS mic-swap kernel on his SII and he is happy with it.
[AT&T Samsung Galaxy S II SGH-I777] EzSqueezeCheese:
Is the mic swap necessary? And if not, does it make a difference between swap or no swap versions?
[AT&T Samsung Galaxy S II SGH-I777] mr-cook:
Yes it's necessary. Your regular and speakerphone mics will be reversed if not.

Does that mean it's a i9100 based rom? I never noticed the one time I used that rom. I didn't use any other kernel than what was packaged with it. I'm still debating the switch though. There are some jb features that I'm just not sure that I'm ready to leave yet.
[AT&T Samsung Galaxy S II SGH-I777] mr-cook:
No. I think it was just a difference between AOSP and stock based ROMs.

[AT&T Samsung Galaxy S II SGH-I777] EzSqueezeCheese:
I see. Tell me, why isn't cm10.1 getting "rc" status? Are they unable to resolve the memory leaks I hear about all the time?
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
There will never be a CM10.1 RC for the SII because Samsung will not release some proprietary files that are necessary to make it stable and stop the memory leaks.

As for the mic-swap thing, any ICS ROM that was made specifically for the SGH-I777 does not need a mic-swap kernel. Unfortunately, that only applies to the stock AT&T ROM and my own Semi custom ROM which is based off of the stock AT&T release.

All other ICS ROMs (including CM9) are based off of i9100 ROMs and therefore need a mic-swap kernel in order to make everything work properly.
[AT&T Samsung Galaxy S II SGH-I777] EzSqueezeCheese:
Thanks for the info. I did notice a thread a while back title "Push Samsung to Release Exynos Source" I do love the functionality and performance these stock roms offer, but I have a huge hard on for cm based roms. When the time comes for me to upgrade to a new phone, I'll definitely take into consideration the likelihood of a stale cm being developed for it. TW... Some days I like it, other days it's hard to look at.

So... I'm back. Its been a while.

I'm having MMS issues again. Ive tried the stock APNs in the initial post, as well as the other attempts from my last posts.

It got to the point where every time I added a new service card, I'd have to cycle to the next MMS proxy to restore my MMS.

But now, NONE of the proxies are working. I have oy the StraightTalk APN and it currently has the 66.209.11.33 proxy. I was able to send one MMS with that, but as soon as I attempted to receive one I lost all capability again. I can surf the web on data no issues, but MMS doesn't work at all.

Google turned up nothing, so I'm asking you guys. Any pointers?
[AT&T Samsung Galaxy S II SGH-I777] razen_kain:
Do you have the straight talk sgs2 or are you on the bring your own phone deal?

[AT&T Samsung Galaxy S II SGH-I777] Titan380:
Straight out of the box original MMS proxy for the SGH-s959g is att2.tracfone.com. With some of the roms you can only have one APN stored in the phone for MMS to work. For good measure delete all but one you have saved in the phone. Now edit your APN and make sure MMSC is correct also. Make sure to save your new APN after editing. Below is the MMSC you want and three MMS proxys . I have used them all with sending and receiving mms. Hope this helps.

Not in a great place for the time being, but that will change. Things get better :)

I do not know what the ota mods are to be honest. if I can get a good concrete example of the ota stuff that does & does not work and then find a link to the source for the kernel that does work for ota stuff then it would be trivial to make it work.

When I am finally out of the hospital for more than a day or 2 at a time I will look into this, it seems to be 1 of the few remaining useful ideas left for the SGH-I777.

Dead battery?

Just curious if anyone has drained their battery to where the phone would not power up, and tried the "covering two battery pins" method with any kind of success?? I sold my 959g about a week ago, and the guy let the battery die completely, and it will not do anything!! Thank you in advance for any help/input on this issue...

I use s3 with some work around to hold tight in place and charge for 10 minutes then place back to 959 device and charge full without problem.....

Do u mean that u put your s2 battery in your s3, and "shim" it so to speak so that it touches the terminals, charge it, then put battery back in the s2? I've been trying everything, and the phone is heating up pretty badly!! Its not the battery that's heating up though, its getting real hot on the top part of the phone by the earpiece!!! The guy even went and bought a brand new battery and still nothing!! I don't get it, I had the phone for 5 months without any issues, and I sell it and a week later this happens, I just don't want to look like the bad guy here, and seem like I ripped him off or something... I'm trying to figure it out, to no avail...
