on the cm 10.2 instructions it says this to install a modem
do you we need to install this exact modem after each rom install (not just cm) or are there other stock att modems that should be flashed after a rom? I'm pretty new to rooting/flashing on LG. I had an optimus L9 but it seems things changed a little or maybe it's just the lingo. any help would be appreciated. I have decided to stick with LG from here on out so if you have a beginner's tutorial or guide that would explain alot of these things that would be very helpful. one more question I have is that on a roms OP it says to wipe data/cache/dalvik in addition to your system, is this good practice when installing any rom? would wiping the system erase cwm and any root files or am I wrong on that one?

As far as I can tell flashing modems doesn't actually do anything.

I saw someone else say that but if flashing modems are pointless why would all the devs be saying to in their rom op

Probably because they are operating under the same misconceptions as everyone else. No shame there, because on other devices, it does work, but we have to deal with reality, and that reality is clear: flashing modems on the e980 via CWM/TWRP for reasons yet unclear does not actually change the modem.
Flashing via LG's ancient and super-crappy tools does.

I agree 100% I have tried flashing countless modems every which way possible... and never had it actually change my modem.

[Q] In need to some help, need to reset or nuke my phone.

OK, so here is my deal. I got my SGS2 a little over a year ago. With the help of this forum I was able to root without issue and flash many of roms. I am now at a point in my playing around that I am having issues doing anything. I would like to just factory reset in Kies, but I can't even do that. For some reason (I have a telus phone), Kies thinks I am a T-Mobile phone, or at least its what I can tell. When I launch Kies and it displays the phone and the and its settings eg: PDA, Radio, etc they all say TMB. I have no idea if that has nything to do with it or not. I tried flashing the Telus radio via Odin, though nothing changed in Kies. The last ROM I used seemed to have screw my Clock Work Recovery and I cannot figure how to get it back. I have tried re-flashing CWR, but I don't think I really understand the difference between Touch and Touch-less. As you can see I am fairly lost at this point. I am turning to all of you for help. I am open to trying anything, just point me to some guides, tips, tricks. I have tried a ton of stuff with no luck. I know these questions get asked all the time and I apologize for making another. I would not be doing so unless I really needed the help as usually I am pretty good with this stuff. I appreciate everyone in this forums and all the time they have put in to bringing us great information. I am thankful to anyone that can help me out. If you need any further info please just ask and I'll provide it as fast as I can!

I have, actually I may be running it now actually. It just seems like I have a lot of over lapping stuff. Things that were not fully removed, parts left behind, etc. Is there a easy way to lock up what ROM is running. I assume it's the stock rom as I have the Samsung Apps application on my phone and that is removed with most custom roms. Like I said I really just want to nuke this biatch and start from step one again. She is running like crap atm.
If you flashed the stock Rom you won't have cwm any more. You'll have to reflash it. The phone will be like it was when it was new.
You can get the stock Rom from Sammobile.com for your device and carrier. You 'll have to extract the tar.md5 file out of it using 7_zip. Then flash it with Odin

I think the reason I am confused is if it worked, which it appears that it did why does it retain all my data? I would just like to totally kill the ***** to nothing. I'll try flashing to stock again with the site you provided when I get. I appreciate your help!
When you say kill it, do you want to make it so it never works again?

Carrier specific devices -- what's safe to flash?

Development seems fragmented between all the different carriers.. even with a deodexed stock rooted rom are things "designed" for other carriers not compatible with my Sprint device?
Is it a matter of n7100 vs n7105? Or gsm/lte?

You will probably brick your device flashing another carrier ROM. I say probably as I know of no one willing to experiment on our rather expensive device.

There are some "ports" that have been done between carriers. Know your carrier and flash only roms designed for or ported to that carrier.
All will run on sprint's variant. The radios may be compatible with the ROM with a few mods here and there. You can flash other stock ROMs. Just flash sprint's kernel with another carriers. You'll see a mostly functioning ROM. Only issues are radio related.

I'd proceed here with caution. I've heard of borked boot/kernel image or worse hboot damage requiring either replacement or j tag service. YMMV.
Sent from my SPH-L900 using xda app-developers app
Thanks for the info. It sounds like it's only a matter of radio compatibility when flashing ROMs. If I flash stock sprint radios and a kernel made specifically for the L900 (stock or otherwise) I should be okay based on what I see here.
So it's only ROMs that are in question here? If there's a .zip mod for status bar, camera, gallery, etc, I shouldn't need to worry about what model it's for? Including n7105 international variant .zips -- I see no reason why that shouldn't work. These are all essentially the same device sans connectivity.
I don't mind flashing sketchy things, been doing that for years and haven't had a hard brick yet -- it's actually hard to do. I just want to know what the facts are about what is known to work or not work.

NOT TRUE AT ALL...........if you flash an international variant rom, while you may get it to boot (doubtful), you will not have service and your IMEI/Baseband will be gone d/t the fact that the partitions are slightly different between the variants. the only fix for this is flashing a stock tar that will re-write your partitions and restore to stock. and it simply isnt as simple as just changing the partitions and kernel either.
so no, DO NOT FLASH other carrier variant roms to the Sprint variant
I flashed a att rom and a tmo theme to mine with success.and by success I mean didnt brick. Now as far as booting thats a diff story. The tmo theme booted with problems and the att rom just bootlooped. But as far as I know the partitions layout is the same(not counting the intl'. I havent looked yet) so i think ur safe to experiment with the average rom. I would check to make sure theres no radio or bootloader and you should be fine.

Open the zip and be sure the only things you see are boot.img, META-INF, and system. If so, flash and reboot. If it bootloops, plug in and use adb to run a logcat to see why it won't boot and attempt fix it. A kernel is not enough to brick you unless it gets flashed over the wrong partition. Which I don't believe is a concern here since the partitions are the same across all the note ii's.

The CSC data needs to be replaced. The kernel should be fine. Some of the etc files should probably be replaced. The build.prop needs to be edited for Sprint/cdma.
Check the install script and compare it to sprints to make sure there arent any partitions being formatted differently. I have used a few different at&t roms on mine by doing the above.

i was referring to the international versions as was specifically stated in the post. even if you change the boot.img to the proper one it will not flash properly to the phone because the partitions are different on the INT version.
the US variants all have the same partitions and will flash properly with the carrier specific kernel minus a few bugs here and there. and doing what shiftr182 said will usually get rid of any other bugs.

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...

Google edition rom on t mobile s4 question

I seen a post where the 4.2.2 Google edition rom was available to flash onto my tmobile S4, I was wondering if I can just flash it after wiping, or if I need the ktoonz kernel? I'm not even sure what the ktoonz kernel is, I've flashed ROMS before, just not on my s4. I'm rooted with twrp. And my build is the UVUAMDL one where I needed to get past boot loader lock thing. Sorry, I'm using my phone and I don't have the right links with me. Any help would be nice

I Highly suggest you don't flash anything until you read up on the forums and figure everything out. Read up on kernels, roms, gapps, bootloader, recovery etc. Then when you get that stuff down read about the roms you want to flash. If you flash am incorrect file you can hard brick your phone.

I'm fairly familiar with flashing. I know my way around twrp and cwm. I just never knew what a kernel was.. Never needed to use one on my vibrant... So I know how to flash, that's not my question... I want to know if, with a stock rooted tmobile galaxy s4 (UVUAMDL), can I just flash the Google edition rom from twrp, then I'm good to go? And will I lose my root? It looks pretty straight forward, I just want to make sure my phone is Ok for the rom, and if I need the ktoonz file, cuz some people were mentioning it...

I already posted the link.
I was looking at that, so I wipe everything in twrp, and flash it like normal, but I'll lose root? Download the chainfire zip and install it in twrp as well to get root again?
Quick question, if I ever wanted to send my phone into get serviced, I can completely wipe my phone back to stock by flashing that back on the phone using Odin, correct? That would do the root as well, so when I sent it in, they would be none the wiser?

Yea that's the version, get the odex version so everything works.
Jellybean doesn't have flash... It uses Google chrome as default browser unlike custom Roms that has a browser that has a browser built in.

Will there be completely stable versions of the Google edition s4 released sometime in the future? I'm just seeing way to many different versions of the same thing where some things aren't working properly, and it doesn't seem to be as simple as just flashing the rom. All sorts of other stuff needs to be done like changing build.prop and whatnot. I just want to be able to flash the rom and be done with it... Is that possible right now? Or no. I guess I'm not as familiar with all the terminology as I thought. I still don't know what a kernel really is, I flashed one once and it just made my cwm recovery menu different... And I know I needed a specific kernel to flash specific ROMS.. Is that the case here with these Google edition roms?

[Q] guys a question about modem flashing

I have an at&t phone my bro bought from NY and it has a UCALJ2 modem and omnirom 4.4.1 on it and works fine unlocked in India.
My question is that will updating it to UCAMH3 will firstly lock the phone?
2nd will it work in india as I think there is a bandwidth difference from US and here tho I haven't noticed any issues as such
3rd will the efs backup suffice from TWRP 2.6.3.1 and is TWRP the best method to flash the zip
and lastly will the flashing work on omnirom 4.4.1 and in case it gets locked any ideas how to unlock it before restore
also to restore what all will I have to wipe?Clean install or will just wiping some stuff do.Thank you just wanna be sure what i'm doing before I flash a modem and take out one of the most important part of a phone
Help is greatly appreciated

You better slow down and learn a few things. I counted three things you did that got you very close to turning your phone into a paperweight.
yeah I know network unlock is permanent but I read a couple of posts complaining that it got locked after a rom flash so was wondering if it's the same case with modem,though most prolly they just had a modem issue that showed unknown baseband,I just searched on forums of note 2 and saw some people post that complain
2ndly could u please elaborate the 3 things so I don't do them
I'm a user not a developer so I just follow the steps I see on this forum,if I have something wrong would be good to know before I progress on
Nothing in UCAMH3 will lock your phone...
But the way you are asking about 3 different versions of android does concern me a bit...
As mentioned above...
Read the threads carefully in the OP for any rom you are considering...
Android 4.1 and 4.2 are pretty safe bets...but 4.3 and 4.4 introduce many changes that are more technical....and missing steps in the later versions "will" cause damage...
Regardless of what you decide...make a few good "full" backups and place them on external storage for that "oh crap" moment...g
