Hey everybody, JT you are a freakin godsend, I just reflashed stock firmware updated to jellybean and installed the latest modem update. It's totally updated stock, if I make a nandroid of this, is that good enough for everyone to flash with CWM?

E: Okay heres an update for you, Motochopper does not root the phone with the latest modem update, so I can't even rename the install-recovery.sh to use the new CWM tar I flashed with Odin.: UPDATE, Ok I got straight into the CWM recovery by booting into it right after the Odin flash, a little tricky but just press on the recovery buttons right when Odin is done flashing and it will reboot into recovery instead of the regular PS which reinstalls the stock recovery and locks you out of root. Use this zip to root while in CWM http://download.chainfire.eu/345/SuperSU/UPDATE-SuperSU-v1.51.zip

The processors and memory capacity on most of these phones are pretty advanced for the tasks they are being given to handle, and slowness in interface responsiveness is mysterious, considering that most of that is just 2-D screen rendering. The real question is why were they slow in the first place. If you were talking about 1080 movie decoding, or something that required alot of processing I could understand some sluggishness, but menus and buttons? Really?

My suspicion is they were probably doing full scale transparency and 3-D geometry (and probably in places we don't even notice), instead of using some shorthand methods for that stuff.

Holy wall of text, Caine I'll make a simplified guide soon for all sgh-i437 users, Odin is our friend. I think I'll pull the modem update file too. JT test builds are good, you can get people to send you catlogs on issues an stuff :D Any chance we can add some new IO Schedulers? The most prominent I have seen used are Row SIO and FIFO besides noop which is already on our phones. :good:

[MENTION=5201401]caine0001[/MENTION] There's no way I was going to quote your last post :) I lost root on the last update, and I have Install_recovery.sh, but I was ready for it. The only thing I can think of is that on my phone su is a system app, not a user app.

One thing I have noticed is that all the updates, including the ICS Odin file are non destructive. Maybe if su resides in /data it survives, but if it resides in /system it dies. Not sure. I'm not as brave and daring as you are, so I'm not going to wipe my phone on purpose. The next time I bork it and have no choice I'll keep that test in mind :)
[Android Q&A, Help & Troubleshooting] caine0001:
Everybody keeps reporting different experiences and asking questions about how to do this or that and what will happen if they do this or that. I was so detailed because I had hoped it would prevent a million questions about "Well did you do this or that" concerning every different scenario. So I went to great detail in making sure that anyone who had any questions or doubts about what they can or can't do or worries about rooting and updating or losing their root to an update would know exactly what I did and what the results were. Saves on a lot of one line posts with questions that half a dozen people end up answering. I know it looks like the Vietnam Memorial Wall in D.C.. I apologize for that. Good intentions....

Mine was a system app before the updates. When I put it back on it went on as a user app. Before I installed Superuser I couldn't get root access but I had it after installing it. I didn't have to run motochopper again. You are saying that you had to run motochopper or whatever rooting program you used again after the update? Just because you had to reinstall Superuser didn't mean that you were unrooted technically. Your apps just didn't have access until you put Superuser back on.
[Android Q&A, Help & Troubleshooting] oldnoob:
Good point. I used OTArootkeeper, didn't do a temp unroot, and afterwards restored root. I didn't really check whether it had root and was just missing the su binary.
[Android Q&A, Help & Troubleshooting] caine0001:
Finally somebody gets my point. I think I was explaining it wrong or something. But anyway, if you get the chance ever again to check it, whether it is after an update or after flashing to another firmware or anything, give it a whirl and see if it is just Superuser that is missing. I am 100% sure that it was all that was missing with mine and 99.99% sure that others will find out the same thing, that they are still rooted but just don't realize it because Superuser isn't installed anymore. And also, when you reinstall it, you only have to do it as a user app and you still have permanent root access. It doesn't have to be installed as a system app again. I know this for a fact since I have actually checked where it is located and it is in /data folder now with my other user apps and not located at all in the folder with my system apps.

Has anyone gotten the update that enables LTE on bands 2 and 5? According to AT&T, it went out July 31st, but my phone didn't find any updates when I just now checked.

Source: http://www.att.com/esupport/article.jsp?sid=KB418485&cv=820#fbid=iBhATrtBsH2
[Android Q&A, Help & Troubleshooting] caine0001:
Yep. Me and a few others I know of have it installed. I just ran Software Updates in the About Device section of settings for the phone. I did talk to AT&T yesterday and I was told that they were having some problems with the update being downloaded by a lot of people and that the engineers were working on it. Maybe that is your problem. But you should be able to OTA it anytime. It updates your modem and the build number. Besides enabling channels 2 and 5 there are supposed to be a few other tweaks. The whole update is only 80.04MB. You might be lucky enough to have someone here that has been able to pull the update file from AT&T and if so they may offer to send you the file so that you can flash it with CWM once they see your post. But if you have to do it OTA you just have to make sure you have your stock recovery back on or it won't install. But if you can get the zip file you keep CWM on and flash it.
[Android Q&A, Help & Troubleshooting] oldnoob:
Do you have the stock recovery or CWM?
[Android Q&A, Help & Troubleshooting] caine0001:
I am sorry. I started replying to the wrong message.
[Android Q&A, Help & Troubleshooting] oldnoob:
Sorry, that question was meant for the guy that needed the update to see if i could help him out, but I just realized a fatal flaw in my thinking. The update won't install with CWM regardless of the form it's in. It would probably be easier just to do the date thing and get it ota.

So basically, nevermind :)
[Android Q&A, Help & Troubleshooting] caine0001:
Correct me if I am wrong, but I thought I read on this forum somewhere, that you could put the original .cfg file into the /cache/fota folder (you will probably have to create the /fota folder) and reboot and it would install. I have never done it but I read that. And by the way, if you take the .cfg file and rename it to update.zip you can put it on your sdcard and use CWM to flash it. Just choose the option to install update.zip from the options in CWM. I have done that on one of my Express phones. So I know that you can do that. Have you heard different? If so, you might want to find a way to try it, because it did work. So at least you can do it that way if the first thing I mentioned doesn't work. Simply rename 2400258.cfg to update.zip and try it.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
I have CWM.
[Android Q&A, Help & Troubleshooting] oldnoob:
[MENTION=436663]caine[/MENTION] I don't think you can use CWM on these updates, I think they fail some kind of security/signature check. I know it wont work with the cfg file, but I never tried the update.zip method with CWM.

[MENTION=219956]Mk[/MENTION] If you want to try I'll get you the file. You have PM.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
Thanks for the update file! Ok, so I updated to the latest OTA and I think I was successful, no errors during update. One thing I noticed is the baseband says I437UCDMG3, whereas AT&T says the baseband should say I437UCBMG3. Unless AT&T made a typo?

Build number is correct though. Did anyone notice this?

[Android Q&A, Help & Troubleshooting] caine0001:
Like I said, I have already used the file that you have to do it with CWM. If someone can't do it then something is different than what I did or their phone is different somehow. I wasn't sure about the other method, but the one with update.zip and CWM I have done it with this update and CWM. So I know that it can be done on my 2nd Express phone.
[Android Q&A, Help & Troubleshooting] oldnoob:
Good to know, that will make it easier for the next update since I'll probably have CWM back on there again.
[Android Q&A, Help & Troubleshooting] oldnoob:
Getting the file is easy when you know where to look, that's the part I didn't know until JT pointed it out. When you download an update and try to install it the system deletes the file whether the installation was successful or not. So if you want to copy it download the update normally but don't install it, postpone it. Once it's postponed the downloaded file is sitting in /cache/fota waiting for the postpone interval to expire. There won't be much else there so it shouldn't be hard to figure out which file it is by the size and date. You need root access and a file manager like Root Explorer or ES File Explorer that can access root privileges to get to it and copy it wherever you like.
[Android Q&A, Help & Troubleshooting] caine0001:
Thank you. I never thought to use Postpone. I have tried looking in the /cache/fota folder both when it was successfully installed and when it wasn't, but it was never there like you said. But using Postpone is a neat trick for getting it to stick around. Isn't it amazing how easy things are once you know the trick? I was racking my brain, but never even considered something that simple. Once again, thanks for the information. It is going to be very helpful on future updates.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
Thanks for the help everyone, I'm on the latest build. The pattern lockscreen looks a bit different. I haven't noticed anything else. Hard to tell if LTE is using band 2 or 5 unless I look.

I had to flash the stock recovery to get this update running. I assume CWM doesn't work with this update? I tried flashing CWM and stock recovery persists.
[Android Q&A, Help & Troubleshooting] caine0001:
I will never understand the difference when the phones are the same model. Here is another one. My pattern lockscreen is identical to what it was before the update. No change at all. In fact, I cannot find any changes in any of the settings options. As far as LTE my phone information is the same as it was before. Under Mobile Network Type it simply says LTE:14. Is 14 the channel number it is using? If so, mine has not changed even with several reboots. It just stays the same.

As far as installing CWM back on after the update, it should work just fine. I reinstalled version 6.0.3.4 using ODIN. But as you probably already know, to install CWM on my Express i437, I have to follow the instructions I wrote in the next paragraph.

If you are trying to install CWM and it just stays on stock recovery you can try to see if you have a file named "install-recovery.sh" in the /system/etc folder. Of course you have to be rooted and using a file explorer program like Root Explorer to get to the file. The update did not remove your root. If you can't get root access with your apps you probably just need to reinstall Superuser, and you can install it as a user app and it will work just fine. Once you are getting root access with your filesystem explorer app and if you have that file, then rename it to something else then install CWM and it will stick. Then when you need to go back to stock just name it back and reboot and it will revert to stock. This is what I do. The only problem is that some of the newer i437 Express phones do not have this file installed and thus there is nothing to rename. But on them, CWM installs just fine. So look for that file. Since yours keeps going back to stock you must be one like me that has that file that you have to rename.

If you cannot find that file in /system/etc or just /etc (if your files are listed alphabetically you will find it just after all the files that begin with init.), then I cannot figure out why CWM won't install. Especially if you had it before, because this update does nothing to prevent you from using CWM. Post back and let us know if you have that file or not and if you get CWM installed. Are you using ODIN to install it or some other means? ODIN worked for me once I renamed that file and it should work for you if you have the file and rename it or even if you don't have the file and just do the install. Like I said, update us after you read this and let us know if any of it applied to your situation.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
I'm not sure what the LTE:14 stands for. It's definitely not the frequency band. That might be the speed cap, ie 14 Mbps download max. Although, you can go above that anyways.

The way to find the band on most Samsung Androids is to dial *#0011#. It should yield an ugly information screen where you can find the band, it's kinda obscure though.

I have the install-recovery.sh file, not sure if it's from the time I manually copied it to the system/etc folder. I'm using ODIN and it could be because I'm entering the bootloader directly via Quick Boot app. I'll try entering the bootloader via turning off the phone and pulling the battery. That way I can accept the warning message. I'll try again later tonight and post back.

Just to add, I found a nifty app called Triangle Away on XDA for free by the developer. It helps if you ever have to send your phone away for warranty. If you notice, the bootloader keeps track on how often you put custom ROMs or recoveries. This let's you reset that to zero and make your phone look like it's never been modded.
[Android Q&A, Help & Troubleshooting] caine0001:
Yes, I like Triangle Away and was ecstatic to find out it worked on the Express. I have had it for several weeks now.

If your phone came with that file then you have to rename it. If it wasn't on it out of the box then it does nothing. Whether you have to rename the file or not, to get CWM to install you don't have to do anything special. Just enter Download mode by pressing HOME, POWER, and VOLUME DOWN, and when it comes up press the VOLUME UP button and connect to the computer. Once ODIN recognizes it just click PDA and choose the CWM file and hit start. If you are using any other apps such as Quick Boot maybe that is interfering with the install. I am no expert here, but it was extremely simple. I wasn't worried about the bootloader or anything. Just entered Download mode and ran ODIN. That was it. That should be all you do. Just reboot clean and simply do as I did above and it should work.

I did what you said and I am on LTE Band 17. I guess the bands 2 and 5 that the update opens up are just extras if needed. And I am sure that the LTE:14 is not the speed cap. When it shows that I run speed tests and get speeds that peg out the speedometer which reads up to 20 mb.

The only 2 versions of CWM that work on the Express that I am aware of are the shabbypenguin OUDHS version and the official 6.0.3.4 version. I compared the 2 and the only obvious big differeneces I found was that with the official version you have the option to save your Nandroid backup to either your phone or your sdcard whereas with the OUDHS version you only have the option of using the sdcard. Originally I thought there was no difference, but now I see that there are a few. But thanks to shabbypenguin we had a version to use that included almost all of the options until we were able to start using an official version. Just thought I would mention this in case some are still using the OUDHS version and are afraid to change to the official. It is worth it to do now. The extra options are worth it.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
OK, I was able to flash Shabbypenguin's CWM. Booting directly into the bootloader with Quick Boot was doing something that was preventing me from flashing it before. I tried flashing the official 6.0.3.4 CWM, but it reverted to stock each time I did it. I wonder if I'm just got the wrong file. Anyone have a link for the 6.0.3.4 CWM file.

Band 17 is 700 MHz, which is pretty typical. I'm not sure what the status of AT&T putting LTE on bands 2 and 5, I'd imagine it's out in the wild already if they pushed out such an update. It also looks like this update really just makes refinements to the existing build. After looking at the lockscreen, it's really the same. It looks like there is more "sharpness" or a more defined look to text and certain noticeable objects. They must have done some kind of display calibration.
[Android Q&A, Help & Troubleshooting] caine0001:
I noticed the crisper image also along with better responsiveness to commands. Screens pop up much more quickly now than they did before. As far as the file for CWM 6.0.3.4 that I am using on my Express i437, if you PM me your Gmail address (or if you don't have one give me whatever email address you use) I will send you a link to that file.

**EDIT** What the hooey... Maybe somebody else needs it too so here is a link where you guys can download the CWM 6.0.3.4 that works on the Express i437. I have it installed right now and have used it and it works flawlessly. Just use ODIN to install. I used ODIN 3.04 even thought I have a newer version. I only tell you this so that you can duplicate what I did that got it to work. I am sure using ODIN 3.07 or another would be just fine, but just in case I am letting you know.

To tell the truth I haven't gotten enough calls to say for certain. All the calls I have gotten so far have rung through. I don't have any showing up in the logs that didn't ring. But again, this could be premature.
[Android Q&A, Help & Troubleshooting] caine0001:
Can someone tell me if this helps to answer the mystery surrounding the new LTE channels that the update is supposed to give us. I did that "*#0011#" thingy you said to do to get service mode information about the channel abd band you are using. I believe that these 2 lines that I copied from that page of information are telling me that I am on channel 5. The two new ones were 2 and 5. Anyway under About Device in settings I click on Status and under Mobile Network type it says LTE:14. Still don't know what that means, but here are the two lines about LTE that come from the info page when you type in the above code:

LTE RCC: Idle, Band 17

LTE DL BW: 5MHz

Does this mean that I am using channel 5? Because it is the only piece of information that I can find that says anything about LTE and the number 2 or 5. It is also saying I am using Band 17. What is the difference you radio frequency eggheads? :) And thanks for your input. I may be way off, but was curious enough to ask.

**UPDATE** I googled it and evidently a channel is a part of the band. A channel is a connection between 2 devices and is located somewhere within a particular band. At least that is what I got. So it looks like I would be using channel 5 within band 17. Is that right?
[Android Q&A, Help & Troubleshooting] caine0001:
How does service center determine if you are rooted?

I have a question for someone smarter than me. When you send a phone in for service I know that rooting voids the warranty, but how do they determine if your phone has been rooted? I know you can't just simply remove the Superuser app or its equivalent. And it cannot be as simple as deleting the su command either. So how do they detect if it is rooted? Just because you remove Superuser or su and as a result Root Checker will not be able to verify Root Access does not mean you are not still rooted, You just need the Superuser binaries back to give access to the apps that need it. The reason I ask is because as you know if you have followed this thread, I have flashed back and forth between ICS and JB firmwares several times (including official unrooted original ones) and never lose root. Sometimes I have to put Superuser back on to grant the access to apps but I never have to re-root. So once again, how do they check to see if your phone is rooted? What is the dead giveaway even if you remove Superuser and su? Because I have no idea how to officially unroot my phone if I need to. I used motochopper to root it, but have no idea how to unroot it. So can anybody help me out with this one just in case I ever have to send my phone in for service? Thanks....
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
Yeah, it looks like you were on band 17 with 5 MHz of download spectrum in the area you were in, which seems lean. I average 10 MHz but I'm close to Baltimore and Washington DC. The folks on Howard forums talk about spectrum like it's military jargon :).
[Android Q&A, Help & Troubleshooting] caine0001:
So actually I was wrong then. The update was supposed to allow our phones to use channels 2 and 5 when on LTE. From what you are saying I am not on channel 5, I just have a data stream that is 5MHz wide. Is this right? Or am I just not understanding something and missing the point.
