Yeah, I think that means you have a data stream that is 5 MHz wide. The update was just to allow the Express to access LTE on bands 2 & 5 or 1900 MHz or 850 MHz respectively. I think presently AT&T only has LTE on band 4 (700 MHz) and 17 (1700 MHz). I know that there were plans to deploy LTE on bands 2 & 5, but I don't believe that they have started. This update maybe future proofing it. I speculate if this is the last update the i437 will see since it looks like this past update was just backend improvements and this was a mid-range device. Heck, Amazon is selling this phone for $229.53 (as GoPhone), which is even cheaper than what AT&T is selling it on the GoPhone side. Look at this...

OK, I'll stop rubbing salt in the wound lol. This phone could definitely handle more than just 4.1.2. I'm just coming from the Droid Charge where Samsung treated it like the red headed step child. That phone came with Gingerbread and died with it. But, Samsung has come a long way and this phone has been updated almost quarterly since release, which are all good indications.

Also, there's CM 10.1 in development, so that's better than official 4.2.2. :D

[Android Q&A, Help & Troubleshooting] caine0001:
I don't have an ODIN flashable file, but if you need to update to 4.1.2 from ICS why don't you just do a temp unroot and run the update OTA? As of a couple days ago I was able to update to 4.1.2 OTA. It didn't unroot my phone either. Of course I have no idea what you need it for so this is just an innocent suggestion. I am sorry if you need the flashable for another reason than simply updating from ICS.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
I don't want to talk out of line here, but I have never been able to do an FOTA on this phone, which I wonder if that is the reason why that poster is asking. Even the update from ICS to JB (previous to this recent JB enhancement) didn't work for me. I was able to use ODIN to flash ICS but I didn't have wifi. But, after flashing again with Kies, I had wifi but still no ability to do an FOTA. I ended up going to an AT&T device store to get JB but that's undesirable to do. I strongly suspect that this was why I may have had trouble:

-My custom ROM counter was more than one in the bootloader. This should be zero. Should have used Triangle Away.

-My binary stated it was custom in the bootloader too. I should have used Triangle Away.

-I have a GoPhone account and FOTA preferences postpaid. Hard to tell if this is an issue. Tried airplane mode and wifi but still failed.

-AT&T had pulled the ICS update or there are other technical issues on AT&Ts side.

-I had not fully removed root before flashing. I should have deleted root backup and root with Voodoo.

The most recent JB enhancement update required me to manually load the update on the SDCARD. I don't know what's going on with the OTA ability of my phone. Luckily, I'm good now thanks to everyone here.
[Android Q&A, Help & Troubleshooting] caine0001:
I too apologize if my post seemed out of line. I didn't mean it at all to sound that way. It was just that I had never had an issue with OTAs even after flashing back to ICS. I never lost root either and didn't have to do a Voodoo Temp Unroot (I found that out by accident because I forgot to do it). I have for various experimental reasons been back to ICS and did OTAs back to 4.1.2 twice now and it was the same each time. The one time I did a factory reset after going back to ICS and then did the OTA to JB and still had root. Of course I didn't know that until I installed Superuser as a user app and found out using Root Checker that I still had permanent root. Before I put Superuser back on it appeared I lost root because with the Superuser binaries gone Root Checker could not get access. But I have never had to re-root since the first time, just reinstall Superuser. I was just assuming it should be the same for your phone too, but that was my mistake.

As for AT&T having technical issues, I talked to them last week and they told me that their engineers were reporting to them that they were having server issues and it was keeping some people from doing OTA updates. It depended on when you tried they said, because it was coming and going. I just happened to do the update from ICS less than 2 weeks ago (after the new modem enhancing update was already out) and it found the major 480MB JB update and installed it on my phone while rooted. I just had to not have CWM on. But the first time I tried and it didn't work. That is why I called and found out about the server issues. Later on that day I was able to do the update. I had thought that they removed it when the enhancement came out but they said they didn't and I was able to do it.

I hope that this information is helpful. And again, I hope I didn't come across in a bad way with my last post. I just didn't understand at the time why you needed to flash to get the update when I had just done it OTA. I guess there is just some major difference between our two phones. My comments were as innocent as an :angel:
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
No, you were fine. You didn't speak out of line anywhere. I was just excusing myself because I was assuming that the poster might not be capable of OTA like me.

I don't think there is a major difference between phones. I think you just narrowed down the issue, which is AT&T. Darn you AT&T! Lol
[Android Q&A, Help & Troubleshooting] caine0001:
Yeah, regardless if it is the server or what they are doing to the phones, I do lay the blame on AT&T. I do know that there are some differences though, and again, that is AT&T's fault. For instance, some of the i437s do not have the file that you can rename to install CWM and also to revert back to stock without flashing. And a lot of members complain that they lose root every time they flash or update. But i think that one is because they just need to put Superuser or its equivalent back on. The root is there if they just reinstall the program to give the apps access. But too many people have problems of not being able to update OTA or something else for it to be just a coincidence, I think. I am lucky to have the phone I have. Never have to re-root and can use OTA even without unrooting, Plus to revert to stock recovery I just have to rename a file and reboot. No flashing. When AT&T ordered up the changes in the i437 I feel they really messed people like us up. But at least you can still get all the updates you need and maintain your root. Of course, it helps that you know what you are doing.
[Android Q&A, Help & Troubleshooting] oldnoob:
I have been giving this some thought since my Express died last night and I have to ship it to Samsung. It's not gong to do me any good since it's an LCD/back-light issue and can't see what I'm doing. Let's hope they don't check too closely or it's going to cost me.

Besides the SU app most of the binaries reside in /system/xbin, with the exception of the su executable in /system/bin. So in theory uninstalling the su app, deleting /system/bin/su and the /system/xbin directory should fully unroot. But as you delete files you may loose root and not be able finish. The order in which these steps are done is critical, I just don't know what that order is.

Another method that should work for a more complete return to stock, in theory, assuming CWM is installed:

- Use Triangle Away to reset the counter.

- From CWM Wipe Data/Factory Reset, then from the advance menus format /system (this will brick the phone but get rid of all traces of root).

- Reboot into download mode and install the original 4.0.4 with Odin, this should unbrick the phone and be bone stock without tripping the counter.

This is all theory since my phone is too borked to try it.

Question about installing app updates...

My phone keeps trying to update the Samsung Link app. Everytime though it says that the package is invalid. My question is this: I have never had a problem with any updates (in fact it updated 3 other apps just yesterday and 1 this morning) with my phone being rooted and having CWM installed. But I was wondering why the Samsung Link app update package keeps appearing invalid. Could this be a result of having CWM 6.0.3.4 installed? The only reason I ask is because it is an actual Samsung app and I know that I can't do an official update OTA for the phone if CWM is installed. So could CWM be the reason that Samsung Link will not update? I am being lazy. I don't want to go back to stock recovery and then reinstall CWM if it isn't necessary. I know I could try it to get my answer, but I thought maybe someone here might know the answer. So what do you say guys? Is CWM the problem?

***UPDATE***Well I decided to not wait. I removed CWM and went back to stock recovery and then unrooted. The update to Samsung Link still partially downloads and then says installing for a moment then gives me the error message that the update package is invalid. So it does not have to do with CWM or rooting. I wonder what the problem is though since all the other apps are updating just fine. If any of you have an idea what the problem might be, please let me know. Thanks.

***UPDATE*** Unbelievabe! I tried something. They had suggested turning off cellular data and just use wifi to get it to work. That didn't work. Well it occurred to me for some reason to turn off wifi and just use cellular data, and voila! It installed just fine. How finicky can these things be? Well, I hope this experience helps someone else.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
That's really odd. I would have said to clear the app cache then put the phone in airplane mode, activate wifi, and finally try again. That's strange that mobile data worked better. I wonder if you had a glitchy version of the play store.
[Android Q&A, Help & Troubleshooting] caine0001:
I don't know for sure. Everything else was updating just fine. It was just Samsung Link. But there is one thing that I am absolutely sure of and it is this: These phones have a mind of their own. What works on one or even several phones doesn't work on somebody's else's. One man's solution is another man's bricking tool. I just had a message from someone who could not root their phone with motochopper and they had JB 4.1.2 on. I know motochopper works on that version of firmware because it worked for me on 2 phones and for many of you. Also, got a message from someone who lost root everytime they did an update to 4.1.2. Now I don't know about anybody else, but I have never lost root regardless of whether I am flashing backwards or doing an update OTA. I believe maybe he does have root still but just needs to reinstall the Superuser binaries, but still it is a wonder to me how different many of these same model phones act.

Low and behold, you weren't alone in your trouble updating apps. It appears it's a known Google Play issue that's getting addressed ...

http://www.droid-life.com/2013/08/1...le-invalid-play-store-error-working-on-a-fix/

I've lost root before. But, that was on the Samsung Droid Charge. I have only tried motochopper on the original 4.1.2 build. Maybe these people are having trouble after the July 31st update? I'm just speculating here.
[Android Q&A, Help & Troubleshooting] caine0001:
Ok, the Play Store thing certainly sounds reasonable. I don't know why it only affected one app, but hey, the logic works for me. As far as the root, he can't use motochopper after updating from 4.0.4 to 4.1.2. He hasn't even gotten to apply the new July 31st update. So I don't know what is going on there. Actually he is the first one that I have heard of with 4.1.2 that can't root with motochopper.
[Android Q&A, Help & Troubleshooting] MkVsTheWorld:
First thing, I sincerely hope that the person messaging you is attempting motochopper on a Windows PC. This phone doesn't work on Mac at all. I learned this from personal experience, I use a MacBook Pro and a Windows 7 desktop and motochopper just doesn't find this phone on Mac OS X. Hopefully, this person is using at least Windows Vista.

Secondly, this person should uninstall all instances of Samsung drivers, reboot, plug the phone in and let Windows find the drivers. Try motochopper again. I can confirm this works on Windows 7 64-bit.
[Android Q&A, Help & Troubleshooting] caine0001:
Yeah, that is what I use is Windows 7 too. I assume he is because he used motochopper to root it when he had 4.0.4 on it. So it isn't a problem with motochopper. Me thinks he is still rooted and just needs to reinstall the Superuser binaries. Just my opinion though.

Noob here

Hello all,

So I have a 437 that was rooted running 4.1.2. Somewhere down the line an app was downloaded that threw my phone into an endless boot loop. So I flashed 4.0.4 and then updated to 4.1.2 using a zip file on a SD card. I was under the impression flashing a recovery didn't delete data. At no point did i wipe or recover. Just flashed in Odin. If I was mistaken then shame on me. But i'm hoping that I just don't know where I'm supposed to look for the files that were on my internal storage.

Thanks for the help either way.
[Android Q&A, Help & Troubleshooting] phrozen_flame:
In regards to my boot loop, i'm only speculating. With the amount that I did to my phone it could have been a number of things. It started slowing down and randomly restarting a few days after i installed mightytext but i uninstalled it about 2 weeks ago and my phone was still sluggish and crashing. It use to stop when i turned off data and WiFi, it was almost like it was trying to connect to something, like when a website crashes a browser. (i'm trying my best to explain, i'm sorry if I'm not making sense.)

Turning off the data stopped relieving the problem and slowly time between reboots became shorter until it was in a full loop.

So i decided to just flash the 4.0.4 stock rom found in this thread. I was hoping flashing without wiping or resetting would save my personal data, pictures and whatnot; contacts and apps I can always get again through Google. Once I flashed 4.0.4, the phone wouldn't boot past the "think possible" screen. So i used the zip update to 4.1.2 found on this thread and installed through recovery mode, as a last ditch effort. For whatever reason it worked but everything on my phone was gone. Then it updated to the new update just rolled out automatically.

I tried various data recovery freeware, and all it could find was some album art. What I was hoping to recover specifically was a [.folder] that I hid. But I've conceded to the fact its gone since ES can't find it. I've rerooted and have decided its safer to freeze various bloatware instead of backing up and deleting. This is the second time i've had to flash my phone so i'm thinking be deleting all the stock apps have something to do with it as well. I'm new to all this, so i've been haphazardly tweaking my phone so it can do cool things and then facing the consequences.

You live and you learn right?

Can anyone help me ! I want to install cwm provided by jt1134 ! Flashed through Odin 3.07 but whenever I try to go to cwm,it boots me to the Stock Recovery ! Help please its urgent !
[Android Q&A, Help & Troubleshooting] caine0001:
If you have an i437 look in the /etc or /system/etc folder. If you are rooted you can use something like Root Explorer or something like it. Look in either of those places for a file called "install-recovery.sh" and if you have it, rename it to something else. Then install CWM and it will replace your stock recovery. That is what I had to do and several others too. But there are a lot of newer i437s that do not have that file, but they can install CWM just fine and it sticks. If yours keeps reverting back to stock, I would say you are like me and have that file. Just rename it and you can install CWM. But again, you have to be rooted so that you can rename it. You can't use the built-in "My Files" app. It has to be a quality after market file explorer like Root Explorer, ES File Explorer, FX File Explorer, etc., so you can see files that are normally hidden and then rename them.

---------- Post added at 12:46 PM ---------- Previous post was at 12:36 PM ----------

Flashing back to 4.0.4 is what lost that data from the phone. That is what happened to me. That is why I had a backup of all my apps and settings before I flashed to a different firmware.

Be careful even freezing system apps on the Express. I did that to just a few very innocent apps and it resulted in my phone freezing up. I found that it wasn't worth the effort to freeze any apps. I could never figure out which ones were causing it to freeze. Maybe you will have better luck than me.

BTW, are you saying you finally got it to root? Congrats. Did you isolate what it was that was preventing you from rooting when you posted before?

I think that it can be renamed to .zip and used in recovery. However that doesn't help when you have no recovery.

You need a stock recovery file to flash via odin. They're either .bin or .md5... I forget... it's been quite some time since I read up on odin. I'm unsure whether the ota update can be converted.
