Getting phone Friday - question about rooting and other advice

well my phone arrives friday. i'm coming from the evo which i have rooted running cyanogen mod. i've been reading the forums alot and one thing i keep seeing that i'm clueless about is ODIN ? i've never seen this term used in android hacking before.
a few questions
best and easiest way to gain full root? recommendations for a custom rom? it doesn't look like you can run cyanogenmod on this?

odin is progam for you pc (if you have mac you use something else check dev forum) odin allows you to flash modems and .tar files while in download mode on your e4gt, easiest way to root your phone is through odin took less than 5 - 7 minutes

The modem is separate.
Sent from the future.

I just want to add, be very careful about what you flash and make sure there is a way to go back to a full stock phone (modem, kernel, and ROM) before you do anything. Many of us who upgraded to the EG31 modem are sitting in limbo right now because there is no way to go back to the stock EG30 modem.

Don't wanna hijack this thread but don't wanna start a new one, ill be getting this phone soon and I've been reading around and have a question.
What exactly is a modem? What's it do ands how does changing it benefit us?
I'm familiar with rooting and kernels and rom's and all that jazz but I have a hero so I have no clue about modems.

im new to the term modem too, and ive asked the same question. i have been told the modem is also known as the radio and that this is how the device picks up the network signal. i cannot confirm this is 100% accurate but this is only what i was told when i asked the same question

I was one of those people that fell into this category. As it turned out I had 1 day left to return my phone so I returned it for another one. Now I am content to wait on the official update and give the dev's a chance to catch up. My advice wait it out, its not like this phone is a pig outta the box........just my .02.

Few sugestions to the moderators.

I just moved here from Epic 4g forum,and I like that these threads are kept clean unlike old Epic forum.
I would like to suggest one thing though.I had to look through tons of pages to find out which modem/kernel/official rom update is the latest.
I ended up rooting through Odin EL29 rom and then double rooting in order to install cwm.And I still don't know which modem is the latest.
Plus on regular Epic it was better/recommended to update to latest official build rom before rooting and installing cwm,which I found out on here when installing cwm that cwm for older builds(EL29/26) was different from other cwm's.
It would be great if there was new thread in development section that stated which /modem/update/kernel was the latest,how to flash cwm if you already rooted and if I should update to latest update leak/kernel before flashing certain rom or cwm.
Just a suggestion for noobs or people that just got here,thanx.

Don't mean to be a a#$ but if you just looked you would be able to answer what questions you have or posed. Also their is a sticky in the development section its the E4GT wiki and it shows everything release dates for modems and links and anything else you may need. Its pretty up to date.

I was thinking the same thing lol. The modem threads in development are in order from old to new, and it even says so.

Thanx,on wiki there still is no way of telling which modem is latest,i wouldnt know that they wewre in that order if you didnt point it out.

Yea its confusing because of the letters and numbers. I wasn't sure at first myself when I was looking to flash the latest radio.

[Q] [HELP] Soft Bricked i9505

I rooted my GS4 yesterday and had no issues at all until i tried to flash a MOD to obtain wireless hotspot, but what i didnt notice was the MOD was for a Sprint version GS4. I know know if thats exactly what made my phone brick but im pretty positive because it was during the reboot that the phone got stuck on the TMO screen and apparently remaining soft-bricked. I spent the rest of the night and all of today reading and researching how to fix it myself before coming here to ask for help, so please bare with me.
I have already attempted to flash the official stock firmware using Odin, but it displays an error everytime saying it failed and something about AUTH. Sorry if im sounding vague, i am on a back up phone to use the internet and forgot to right down the exact message.. Anywho, i tried wiping everything and redoing the process and i even tried to flash the appropiate PIT file that i found but it still displays an error and says failed because of some AUTH or SEC problem.
Ive been at this diligently for almost 12 hours. My brain is filled with all these suggestions and methods that i have tried to use to restore my phone back to factory, but none of them have worked. I can still get into recovery and all that, so im assuming that there is still good chance i could fix the problem?
Also i am starting to get myself more and more confused about whether the firmware i downloaded is the right one i need for my phone, it seemed so at first but now i see theres TONS of region codes that can determine the firmware version?
Sorry if im all over the place, but i just dont know which step to take next..
I appreciate any help that is given, and im even willing to pay (some) bucks or maybe even (btc) for someone to walk me through what i need to do or what im doing wrong.
Thanks in Advance

Have you followed every single thing in the return to stock thread? Including updating your drivers, using the USB cable that came with your phone, running Odin as admin, etc?

No i havent tried that threads strategy, although i have done the same exact steps but only difference i see is that the firmware file name is:
M919UVUAMDL
While the one i was trying to use earlier was:
I9505XXUAMDM
This is where im getting very confused because i cant find a cut and dry way of knowing which firmware is the correct one..

You do have the T-Mobile SGS4, correct? Any files with I9505 in the name are for the international version, which is what you flashed (not the right file). All of ours will mention SGH-M919, M919, or jfltetmo in the file name. Pull the one in the thread I linked above and push that.
Crossing your fingers while doing so couldn't hurt...
Edit: I'd recommend using the "Download UVUAMDL Official TAR" in that thread as well, not the "stock tar (original)", since the MDL is official.

Thanks so much, i feel stupid for not realizing the difference between the two haha. Im d/l the firmware from the thread you referenced as we speak so i definitely will keep my fingers crossed and let you know how it turns out!
Thanks again. Im not sure how to give a thanks on here or credit for you help but your help is definitely appreciated.

error post

If you can get into download mode i would suggest flashing stock with that then rerooting that way the program downloads all of the nessacary stuff on its own.

[Q] Galaxy S3 - No Signal After Flash

First of all I would like to say this is my first post and I am feeling very optimistic as I have seen all the great things you guys have done over here! I understand in order to solve my problem I will have to be as detailed as I can, but please bare with me as I am a noob to this stuff and seem to have run into some trouble
Okay so I got a new S3 Last week and wanted to try it out on some new custom roms, I flashed it to CM 10.1 nightly using the roms downloaded via GooManager, all was fine and I had no problems until i flashed to a newer version of the nightly build and lost my signal, it always said Emergency calls only.
This happened to me once before but I solved it by flashing a modem file via Odin, since then I had to preform full system reset as I was considering selling my phone, it didn't come to that and now I am back to square one and once again I have no signal.
I have tried flashing the same modem file as I did before with no effect this time round
I have since tried many different modems and completely forgot which one has worked in the past. I have no back up files what so ever so I need to know what it is that is causing it not to get a signal. Could it be the kernel I am using? or is there a pacific modem for my ROM which I need.
I understand this is my own fault and stupidity, you guys are my last hope, I have also tried stock firmware which also has no signal.
It is an international i9300 with UK T-Mobile.
Please help me save my phone!

I hope you didn't flash a Tmobiles modem, because international gs3 and SGH-T999 aren't similar I believe other than looking the same. And more than likely you've lost your IMEI. Please goto settings and check your IMEI. Please do not post it, just verify if it's 0 or a 16 digit string.

Welcome to the forum! Albeit not quite the right one.
You need to post this in the international forum. This is for the US/Canadian models only. They are very different from yours, and not many people here will know much about it.
Do not flash anything you find here! It is highly likely to brick your phone. If you flashed our modems. Consider yourself lucky and now you know why it isn't working. Check with the guys in the other forum for your next step though.
I wish you luck!

As stated, incorrect forum. I'd give you the proper link if I was at a computer. But thank you for the detailed panic free post. It's seriously appreciated.
You're going to end up having to flash the modem that's for your phone, or maybe Odin stock.

You are right I have no imie number just a 16 digit string :/ sorry guys for posting in the wrong arearly next time I will make sure I will post correctly.
I am strating to get concerned, is this an easy fix? I dont mind wiping any data or using a certain Rom I just don't know which modem to use, some modems show me my bars but it still wont get any service. This one currently just shows a circle and cross icon with no bars at all. I am running stock.

I apologise thank you for the link, if I run into anymore trouble I will post to the correct section. I am glad to inform you I have solved the issue. It turns out I installed a bad modem which actually changes the file type of type of the efs folder. Causing roms to not reading it properly.
http://forum.xda-developers.com/showthread.php?t=2377731
I fixed the issue by installing a stock firmware found on this post...
http://50.23.216.69-static.reverse.softlayer.com/showthread.php?t=1646610
This firmware carries a modem file which can read the modified efs folder, and in result restoring my IMEI Number and signal even after I flashed the rom to CM 10.1.
I hope some one else can stumble on to this and it helps them, please be aware though I have an intervention Galaxy s3 and this may not work in the states or other parts of the world.
Thanks again massive help, its people like you that make this the best source of information on the internet!
Once again really sorry about posting in the wrong forums, I will try not let it happen again in the future!

Congrats, I'm glad you rectified the problem! Remember for next time, when you're not able to access data or you're stuck at 2G that your IMEI has most likely went! For future reference, I recommend making an EFS backup. We've all been there before and we know the scare!
And btw, welcome to XDA, enjoy the stay lol.

Yeah I have double backed up and thanks for the tip I will keep that in mind thanks again dude!

Yesterday I flashed S4 Revolution v8.0 [ROM][4.3 MJ9] then I lost my signal and imei and the baseband version is empty although I wipe my cash and data before flashing this rom.

I don't think that's a Rom we have for our device, unless I overlooked it.
Googled it and came up as an I9300 Rom. If this is what you flashed consider yourself extraordinarily lucky it's not hard bricked!
Odin flash the firmware for your model only! Hopefully that fixes it.....
And NEVER flash a Rom not for your model device.

[Q] New Modem?

Hello. Im currently using the UVDMD5 modem for the Tmobile S3 and get decent signal. Ive tried others, but they dont seem to help much. Has anyone had good experience with the UVUEMJC or UVUEMJ4? I see UCUEMJ2 is ported from ATT. Is there anything different I need to do to flash that? If its ported from ATT, what exactly does that mean for signal?
Its been so long since I changed my modem, ive kinda forgotten how to do it :/

Anything as to what I need to do to use the UCUEMJ2 modem?

Should be able to just flash normally. They are on the same partition, so if it doesnt work, it shouldn't be a problem to just flash back to a T999 one. I haven't been around much recently, can't remember much about it tbh.
As for others experience, it will have little to do with your own. Different people have different "best" modems. The only real way to know which will work best for you is to try them out yourself and see.
Sent from my SM-N900T using Tapatalk

I think I read somewhere that in order to use UCUEMJ2, you had to flash something else first? But now I cant find it...

Probably a kernel. Just a guess though.

Hmmm. Can anyone else help?
