OK, Now that we have our own section. How Many REAL IMEI Issues?

With all of the forums merged it was so hard to get a read on the real amount of IMEI Problems by AT&T Users.
So a quick poll / count. Who has lost their IMEI on AT&T.

I lost my IMEI on my first Sgs3, went flash happy (only AT&T ROMs) but still had data and cell. Not sure where I lost it, but I noticed when I was flashing back to rooted stock from early CM10 preview (official) is when I noticed.
So far with my new phone, I've done the same and still have it. I'm now running Aokp jellybean.

I've had no problems as of today but the fear of losing my imei has definitely caused me to not experiment as much as I would like to! I've rooted, installed CWM-Touch, flashed Ktoonsez Kernel, and flashed back to the AT&T Kernel. I'm honestly afraid to try CM as it seems that ALOT of the people who have lost their IMEI had flashed CM10 or CM9. I bought a Galaxy Tab 2 7" a few months back and it's become my tinker toy to flash ROM's and mess with. I don't want to screw up my $500 Galaxy S3, I like it too much!

I voted as flashed a few, but really it is probably closer to many. Only AOSP based ROMs though. CM9, CM10, and AOKP plus updates for each. Also both Faux and Ktoonsez kernels at various times. IMEI still present.
I do make sure that I flash the EXACT same way every time though since it has worked so far. Only thing I have changed now is moving from latest non-touch CWM (installed through ROM Manager) to latest TWRP (through Goo Manager).
If I end up losing my IMEI without adding variables to my flash process, I will start to believe it is a random occurrence. Until then I have to think partial user error coupled with a bad update script or recovery.
I ALWAYS download the file straight to my phone via WiFi.
Reboot into recovery. Wipe>Factory reset.
Flash ROM.
The last couple days since moving to TWRP I have felt more ballsy and did things a bit differently.
For the first time, I also wiped cache and Dalvik before flashing JB AOKP last night
Still no issues.
Today I decided to flash the ktoonsez JB kernel. I usually only download via WiFi at home (just to keep minimal variables in flashes) but today I did it at work via WiFi. Still have IMEI.
I have NEVER done a Format System so not sure if that might break something.
My process has been if it isn't breaking, try to keep the process as consistent as possible. If something does go wrong, I can say what I did differently. I also haven't had any trouble with the ROMs I flashed despite only doing factory reset then flash.

How do I know if I have any issues with this. What do I look for. I found out and mines good.

I know you found out, but when it happens you will know.
In some cases it seems as though you only get Edge at your maximum speed, in others your mobile data completely died. Generally speaking, there was a lot of confusion and some issues with clarity regarding the issue.
It's possible that there are several different (but vaguely related) issues going around, now that we have our own carrier based forums that should actually help clear it up in my opinion.
Hopefully we will all reach a general consensus on the acceptable recovery (my vote is TWRP!) and method of flashing. The only thing I've personally considered is that it might be an issue with the files transferring via MTP (only because I've never used a phone with MTP instead of mass storage).
I don't think people should be THAT afraid to flash though. If your flash counter is at 0, Samsung should do a warranty swap for you. In addition, it seems like 2 in 25 people (read: NOT FLASHES, but people.) seem to get the issue based only off of the very small number of people in this poll so far.
The reason the issue is so feared is because those that do get it will inevitably be far more vocal than those that don't as they try to find a solution and vent their frustration. Most of the people in the major thread about it didn't have the issue, but were afraid they might lose their IMEI.

I flashed the stock rooted tar that doesn't trip your counter, then injected CWM with dd. I've flashed everything with CWM since then, CM10 included (once) and I still have my IMEI. I'm running AOKP JB now.

I'm about to root and cwm what's your guys input on the best ways

If you read the thread I mentioned (How to root without tripping flash counter) it mentions "injecting" CWM using a tool called dd.

ppl who scared to flash
Go for nontrip flash root + CWM topic - worked for so many people without issues.
The only way to screw up IMEI with these ROMs is via Odin, I think. Odin is a scary tool without much documentation, and in past used to be buggy.
Once you get CWM - do not use Odin.

Odin is a scary tool indeed. Someone in the IMEI thread said if I was feeling feisty to flash stock nonrooted OTA ROM via Odin straight from JB AOKP. IMEI is still intact after all that I have done. :laugh:
EDIT: Also, anyone who reads this. Try out TWRP. We need more people flashing with TWRP, if an IMEI goes missing while using it we can rule out CWM being the problem as some have suggested.

Flash to stock ROM - OTA?

Hi Guys!
I have plan to buy Galaxy S3 in Tmo (in retail) and have a two questions. Is it safe to flash new phone from Tmo to stock android? I don't want to have any Tmo stuff and Tmo's andro version... Question two is, when I'll have stock android on Galaxy, Do I get an OTA when it'll appear? Or I will have to flash manually when new rom will appear?
Thanks for clarification!
dzordzyk

Now someone correct me if im wrong as i still call myself a noob but i do have basic knowledge but you can always root your phone/odin a custom recovery and then flash a stock rom with all the bloat removed. You could always just remove bloat via titanium back up as well tobyour liking. Check out the development thread. Theres alot to read but theres very usefull info to get caught up on. Hope this helps. Oh and in regards to ota, im stock with root injection and im waiting for todays update to try the root keeper method.

For android builds, or AOSP, there are options. You won't get a pure stock AOSP unless you compile and build it yourself. Though Cyanogenmod and AOKP are modified builds of AOSP that have various mods and tweaks I have been using Cyanogenmod 9 and will switch to 10 once it releases.
You will not receive OTA updates as these are custom roms and updates need to be manually flashed
There is a lot of lingo to learn and lots of mistakes to learn from. You will become addicted to flashing updates and various roms very quickly

Thanks guys for quick response!
Every flash in Samsung which I'd like to do has to be done via Odin? Sorry for 'noob' questions but before SGS3 I had NexusOne - everything was simpler on it
Flashing doesn't void my warranty, right? AFAIK on Samsung we have something called "Flash counter" and if we'd like to use warranty, Flash counter should be "0", that's right?
After buy, Do I have unlock phone or something like that?
Thanks for patience! I appreciate it
dzordzyk

No, you would want to odin a stock injected rom or odin a recovery, boot into recovery and then flash the super user zip. I dont know anything about odins counter but the triangle away seems to be working well on our phones unless someone else knows otherwise.
Confirming that if your on the stock root injected rom, use rootkeeper, do a temp unroot and youll be able to get the ota installed. Mine just rebooted from installation. Working good and glad it was so easy. Abq nm here. Hope i helped.

so, this is a veeery good question that I've been wondering myself for quite some time...If you flash a stock rom via ODIN, and you are not rooted anymore, will you get that rom's OTA updates when available? Please, someone who's done this, reply with some precise anwser! Thank you very mutch :laugh:

+1 wondering if this is true

If you are running stock do you get OTA updates? Of course.

You will get ota updates if running stock ONLY! You can be rooted, but you must not have a custom bootloader. Otherwise it will not work.

[Q] Root+Custom ROM help (i747)

Hello,
In October I purchased my first true smartphone, the Galaxy S3 i747.
Since then I have rooted and just have a few simple questions.
I haven't installed a custom ROM, and I really don't know much about them other than that they are an alternative to the stock android os (4.1, 4.0, etc.) that comes with your phone. I have a few questions about ROMs.
I have heard good things about cleanROM, and I want to download it to my phone, but I can't seem to find my phone's version of it. Does it even exist for my version? If not, what are some excellent alternatives? (Must be able to change status bar, I hate the grey one in 4.1.1, just updated tonight) Finally, with a custom ROM, will I ever have to do anything with the stock OS again? Because I get this error message now after i have upgraded to 4.1.1, that doesnt let me check for updates as I have rooted my phone.
Thanks a ton for your help guys, and sorry for the noobish questions!

I may be wrong but it looks like cleanROM is for only Verizon. I dont think Scott has an AT&T version because he does not have our phone.

I had the same questions as you did when I first started...
Best thing to do is go into the android development forums or the android original development fund a Rom, read some of the posts and feedback on it, and if you like what your reading try it out due your self.
Some roms are built around the stock TWz JB os so looks wise is minimal but alot of the extra crap removed i.e all att bloat crap apps that you never use, and other tweaks here and there.
All this into can be found on the OPs first post about the Rom, and make sure that Rom is due your phone!
Follow all pre flashing instructions, and backup!!!!!
Just flash and test it out, worst case you can just restore back to your back up and it will be as you never flashed.
There is a link with the most common Roms I'm pretty sure it's a sticky, I always use a rom that active support for it so as issues come up, they get resolved.
This stuff can get very confusing, read, search, and just post Qs some people like my self have no qualms responding to repeat questions as we all were there once before.
But search is your friend
Hope this helps!

Dropbox is always downloadable from the play store. Pretty sure it's the same deal with kies air, you can just redownload.
Backup as system is always done in CWM.
Backup applications and data for them,I highly recommend titanium back up, awesome app but phone needs to be rooted, with that app you can backup all your applications, flash a rom then just install titanium backup and restore all applications. It's very nice!

So your phone isn't rooted..
Did you try to when you hold vol- and power does the phone boot into recovery mode which should be CWM ... if that happens you are rooted..
Otherwise try to start all over with Odin and the tar files you need to root.

Odin is used to root the phone from stock.. it allows you to first install cwm and su ..once that is done, Odin isn't used any longer unless your reverting back to stock, CWM is used thus forward.

A noob's guide to rooting and flashing

Looking into rooting? Maybe try this foreign ROM thing? (Not talking about ethnicities here) Here is the place to be.
First of all, make sure you have a T-Mobile Galaxy S3. (Aka t999 or d2tmo)
If you follow instructions here for any other device, even for galaxy s3's of another carrier you are extremely likely to regret it and end up having to unbrick your device because you installed an incompatible file.
You can take your battery out to make sure it says t999 under if you are not absolutely sure.
Rooting is a similar idea to jail breaking an iPhone. It removes what restrictions there are with android devices. Yes, it is perfectly legal.
Which leads me to my disclaimer:
I take no credit for what's posted here.
The only work here that's mine is the organization. Please donate to the rightful people who spent quality time developing.
Also I am not responsible for any damage done to your device.
It is vital that you follow instructions in every exact detail.
Firstly, rooting.
1. Install drivers for your device onto your PC. To do this, you can install Samsung Kies or there are downloads that will install the drivers solely(recommended link for drivers http://d-h.st/zya)(thanks DocHoliday77). If you get to the point where you can exchange files to phone from the computer and vice-versa then you're set for drivers.
2. Do a backup (using Kies or a program of your choice)
3.Uninstall Kies. Kies doesn't play nicely with the program used to root called Odin. So uninstall Kies so Odin can work unhindered. Your drivers should stay. But make sure you can still copy files between your phone and computer before proceeding.
4.Follow these instructions put together by OfficialPhoneRebel(aka EverythingApplePro):
http://www.youtube.com/watch?v=fKwhAVj5Feg Outdated. try CF-Auto-Root
Yes, I used this method and it did work for me.
5.After you are rooted, the first thing you wanna do is either install ROM manager (on play store). Open ROM manager. (Yes, give it superuser rights) and install the latest clockworkmod recovery, or use GooManager to get TWRP recovery, both work, but sometimes one is suggested for the installation of a specific ROM.
6.Now install busybox(also in play store)
7.You're all done!
If you've made it this far, kudos. Now you're gonna wanna get the app called titanium backup and do a full backup of your phone. Also boot into recovery (home+volume up then press power until it vibrates all while holding home+volume up buttons) do a backup through these menus. If your feeling like an over achiever and wanna be super safe then go ahead and back up to both your internal sdcard and your external sdcard. Also it now would be wise to back up your IMEI nv (basically your phone's identity), instructions for that can be found here (thanks to daxecutioner24)
Now you have reached a possible stopping point. Stop here and enjoy root privileges. Continue to read how to install a custom ROM.
Installing a custom ROM(operating system):
GooManager (on play store) is a pretty good directory for ROMs. And is a great place to download them and gapps. Now since not every ROM installs this way it is important to check the main page associated with that page to see if any special instructions are required.
But this is what you generally do.
http://forum.xda-developers.com/showthread.php?t=1946701
Roms:
Gapps can be found either on the ROM's page or through goo manager make sure the firmware versions match up (like android 4.1 and 4.1 jelly bean gapps)
For a pure android ROM I would suggest CyanogenMod 10.1 (the one I am currently on)
For an inverted stock ROM stuffed with fun features I would suggest DaRTHSTALKER S3
For a full list of roms and descriptions or if your just addicted to flashing, then here's the stockpile of almost every rom made for the galaxy s3 t999
http://forum.xda-developers.com/showthread.php?t=2088179
Backups are your friend. Especially through recovery mode. They have saved my butt several times when flashing a ROM went wrong.
And yes it is possible to sim unlock (make it so you can use it on any GSM network(such as at&t or US cellular)) your phone:
http://forum.xda-developers.com/showthread.php?t=2037390
Problem happened and you can no longer boot correctly? This is actually very common.
If you can boot into recovery:
Boot into recovery (Hold home button and volume up then press power till it vibrates all while holding volume up and home)
Restore backup (easiest method)
If that falls through then install a rom by following the instructions mentioned earlier.
If you can't boot into recovery or if those methods didn't work:
You must odin to stock. Follow the instructions here under using odin. Odin and Driver files are at the top of the post. Firmware files (what you put in PDA) are located here
If this didn't work, you may be out of luck, try again and if you are still stuck browse the forums and possible post something under Q and A if worst comes to worse, make sure to describe the entire situation including error messages you may have received so the problem can be pinpointed.
And finally, everyone be nice seeing as I am welcoming very new people to this thread.
Also if any suggestions to improve this post let me know.

I like this post, would save those useless threads how do I root even though it's sticky all over. Also it would be really helpful if you include how to back up your IMEI nv maybe link the thread before they start flashing roms. This is probably one of the most important thing as when you start flashing stuff the IMEI might get lost and without that there is no phone. Everything else looks good.

Yes this works for that all you needed to do is click on the CF-Auto-Root method during the process and that would've been explained to you. I have used CF-Auto-Root atleast twice on two different galaxy s3's running jellybean 4.1.2 and it worked more than flawlessly

Just fyi, though, CF Autoroot aparently does not work fot the new T999L.

No

What about kernels? What exactly are they and how should you flash them (do you even need to)?
Can you still use Galaxy S3 motion activated features after flashing a custom ROM?

kernel is when hardware need something like you bluetooth or need to adjust screen brightness it send a request to kernel bla bla bla.
you can only flash a kernel that is compatible to your rom by rebooting to recovery

The way I understand it is the kernel is the bridge between your input and the devices output. Like the bridge between software and hardware... Sorta.. Ya you don't need to flash one sometimes custom kernels can add features and maybe improve GPS/battery life but I don't use custom kernels much. But that's just me some people are in to that stuff.
And yeah it just depends on the specific ROM for the specific features. I don't know if this is still a think its been a while since I've had some Samsung action but check our hyperdrive they had some good stuff going on when I used em.

Best bet is Google. Everything you could ever want to know about kernels and more! If you want to know about custom ones, read the OP's of the many available ones.

SGH-T999L Progress?

ok so I finally got my sgh-t999L through warranty exchange, and i'm excited to play with it. I rooted it with motochopper and have been looking around, but can't find anything quite concrete, seeing as the original threads discussing the t999L are rather dated. What is the progress on the stock odin? have most roms updated their scripts to include the t999L? Can I flash my previous rom with little to no issues?
Fimrware and radios I'm already aware, albeit I'm concerned about mb7 as it feels a little hot during use. kernels and roms it seems are ok, but I'm curious if there are extra steps to do and such. I can flash twrp 2.6 through odin right?

I wouldn't say any of it is dated...its barely been out over a month if I'm remembering right. And the development thread is still fairly active. I am stalled on the Odin part until we get another dump of some of the partitions, (motodefiers working on that) but this really is a non issue anyway. It may take an extra step or two but we can easily get the same result as a full firmware flash already.
Besides, other than kernel, system and recovery, everything should still be MB7 on your phone, and you should not be looking at changing that.
As far as roms having added the asserts, I don't know. The only way to know is to try them. Or open them and check the asserts.
And what is your previous rom? Cant tell you anything about it unless I know what it is. Why are you concerned over mb7 firmware. I wouldn't put much worry about that as its all that's available for now. What extra steps are you looking for? What is it you are trying to do?
And yes, you can flash 2.6.0.0 twrp.

Not dated like really old, but at that time you hadn't made much progress. Just found your thread about the stock rom. So you have made much progress. At the moment I was furrently running vanilla rootbox latest nightly, hiw would I check asserts? Not really worried about changing firmware, just felt a little hot. This being new I understand there are no other radios.
Also thanks for the quick reply

I don't see any reason it wouldn't work. I think I misunderstood something earlier, but ant rom you see in this forum should work fine, its just some won't flash without "help".
The asserts ar in the updater scripts. They determine if certain properties match before allowing something to flash.
Ill be posting a lot of info soon...

Tyvm. It will come in handy. I haven't even gotten to the ROM flash yet, though I have installed twrp. Will be creating a new thread... But I'm having the WEIRDEST bug trying to pull everything off my internal SD on my t999. If its more than one file, windows gets stuck on "calculating time required to copy"
