Samsung Galaxy Express SGH-I437

the guys are currently testing a system image 4.1.2 who created caine0001 I have tried to install on my 2 phone samsung galaxy express i 437 and in both there is a problem with the connection to Wi-Fi switch on is not active on the firmware 4.0.4 everything works fine set the image-Wi-Fi is not active to look for the problem in the image probably some connection settings are stored, by default, can someone tell what could be the problem
[Miscellaneous Android Development] caine0001:
If anyone can help, we would appreciate it...

The image I made of the Express i437 is a clean, out of the box recovery made with CWM. It works perfectly on 2 phones I have access to but fantom35 cannot get the Wifi to work on his he says. He is in the Ukraine he tells me, and the phone I used was an AT&T phone from the US. Is there an extra step that I need to take so that it works internationally? Do I need to unlock it? Does he need to unlock it? If anyone can help us understand what the answer is so that he can use this image that works fine on 2 phones we have here in the states, it would be greatly appreciated. If I did something wrong, please tell me. I am not too proud to accept the help.

His phone had ICS 4.0.4 on it before he loaded this recovery which is JB 4.1.2. Does anyone have any idea what we need to do? He has included two pictures of his network settings and you will notice that the Auto Connect choice is grayed out. I don't know what is going on, so that is why I am asking if anyone can help us out please? Thank you.

I have included the same two settings pages as photos. These were taken on the first bootup after installing the recovery. After these photos were taken I put in my password for my wifi and got an IP address of 192.168.1.175. Can anyone explain why it is working on 2 phones I have but not on his?

If anyone wants to try the recovery image and judge for yourself or maybe even be able to provide us an answer to why it won't work for fantom35 here is the link to the recovery image:

photo working wi-fi on firmware 4.0.4 interesting that the Mac address of the Wi-Fi network that your device is different from the Mac address on my other devices
[Miscellaneous Android Development] caine0001:
Mine should be different...

My MAC address should be different since it is the physical address of the actual hardware (the wifi card). Every phone has a different MAC address. Changing the software on the phone isn't going to change the MAC address.

Another On-Topic question about CWM...

Since this thread is about CWM recovery I believe that this is the right place for this question (more like a problem). Here it is: Does anyone have the stock recovery that comes on the Express before you install ClockWorkMod? I want to put it on one of my phones but since I installed CWM before booting up the first time it will not revert back just by rebooting like it normally would. Usually you have to rename a couple files to make the Express keep CWM and when you want to go back you just name them back to original name. But I found out that if you install CWM before you allow it to boot up the very first time out of the box, then CWM remains your recovery and it does not revert back. So that is my situation. I installed CWM before letting the phone boot up the first time and now it won’t allow me to revert to the stock recovery. Any solution? This is an unrooted phone that is brand new. Never even had a SIM card in it. Just installed CWMusing ODIN before booting the first time. Then booted up and then rebooted into CWM and created a recovery image for the Express. Now I want to put the stock recovery back on the phone and it keeps holding onto CWM. Is there an answer for this?
[Miscellaneous Android Development] Everhez:
that bad for you buddy, but I think in other threads have uploaded the original recovery of the samsung express i437
[Miscellaneous Android Development] caine0001:
Not really that bad

Not that bad. I found 2 posted up. Plus I realized that my rooted phone with CWM on it just had to have the file install-recovery.sh named back to its original name and then reboot and it goes back to the stock recovery and I just made an image of it. Then I renamed install-recovery-sh to install-recovery.sh.old and flashed CWM back on and now I have my stock recovery image file and got my rooted phone back to CWM recovery.

No, this is for the i437 Samsung Galaxy Express.

General rule of thumb when flashing: NEVER use files meant for a different phone. You should always find files for your model (even small distinctions between model numbers are important) or port it, if applicable.

I learned this the hard way. ;)
[Miscellaneous Android Development] oldnoob:
Just bought a refurb i437 that came with 4.0.4 and decided to try to upgrade it out of the box with your nandroid. I ran into the same problem with wifi not starting. I think the problem might lie in the baseband version, the backup doesn't contain a modem image so you wind up with the new software and the old modem. Not sure if that's the issue since I've used mismatched software/modem versions successfully before but it's the only thing that comes to mind.
[Miscellaneous Android Development] caine0001:
I am sorry it didn't work for you. So I have a question for you or any of the experts here. This is something I cannot figure out. My Nandroid backup of an i437 Express with 4.1.2 (it started out with 4.0.4 but it upgraded OTA) didn't allow the Wifi to work on 2 people's phones who had 4.0.4 on them to start with. I took my phone back to 4.0.4 and then installed the same Nandroid and everything worked fine. Why would it work on my phone but not on their's? Is it because I possibly have a different type of network interface installed in my phone than they have? It doesn't make any sense to me and I feel bad because I did everything correct I believe and it is a Nandroid backup that works on my phone but no one else's. Can anybody at all explain this? The link to the 4.1.2 Nandroid is in the first post on Page 7 of this thread. I hope someone can enlighten me. I really want to be of help to those that need it.

Can you explain what you mean by supplying a modem image and how to do it? I have never read anything on it. If you explain I will do anything that you need to correct the problem.
[Miscellaneous Android Development] oldnoob:
The modem (or radio) image is the part of the firmware that deals with the transceivers, the GSM cellular, UMTS/HSDPA, LTE, WiFi stuff. Which version you have can be seen in Menu > Settings > About Phone > Baseband version. ICS is I437UCLI6, JB should be I437UCCMB3. When I applied your nandroid it brought the Android version to 4.1.2, but the Baseband version remained at I437UCLI6.

Don't have a clue about how to extract them, wish I could help. Right now I have other problems, I can't get the OTA upgrade to work, it fails during installation. I've had the new phone for less than 24 hours and I've already borked it, lol. Late tonight after I get home from work I'll try reverting to the stock recovery to see if that does it, if not I'll have to try to find the full stock firmware and reload it.
[Miscellaneous Android Development] caine0001:
You are right. I took a 4.1.2 phone and put 4.0.4 on it and wifi didn't work just like going from 4.0.4 to 4.1.2. And the Baseband Versions are different just like you say. So I believe that you have hit the nail on the head. But now how to fix it. If you let a 4.0.4 phone do the upgrade to 4.1.2 using OTA, then wifi works fine. So there must be some way to change it so that it works with the new firmware.
[Miscellaneous Android Development] oldnoob:
Apparently the OTA update includes a modem, but CWM doesn't back up the modem. I'm sure you can dump and load it using dd if you know which partition block it's in, but I would screw things up if I tried. Think I'll stick with my original plans of trying to restore to stock first.

Samsung Galaxy Express i437 AT&T stock android 4.0.4

http://hotfile.com/dl/204763916/e45faeb/I437UCALI6_ATTALI6_ATT_USA_ATT_Android_4.0.4.zip.html

i downgraded my SG Express i437 from android 4.1.2 to 4.0.4 stock rom and the wifi started to have the wont turn on problem. As caine0001 wrote it can be fixed by upgrading the stock rom via OTA in options>about the device> system update. but i dont have 3g/4g so i would like to know if anyone got a file tar.md5(for odin) but with a version of jellybeam instead of the stock rom(4.0.4)

anyone?
[Miscellaneous Android Development] oldnoob:
If you are on AT&T, or one of its MVNOs, you can download the update through wifi. I looked for the file but couldn't find anything since I had to reflash back to stock to get it. I guess you would have to be rooted to get at the filesystem to see where they hide the download, but if you're rooted you can't upgrade OTA. It's going to take someone smarter than me to get a copy of that file, or an installable modem image.
[Miscellaneous Android Development] caine0001:
When you say that you don't have 3G/4G do you simply mean that you live where it is not available? If so, aren't you within a decent drive to an area where they do have it so that you can download it with some speed? We just got those speeds where I live, but if it meant getting access to JB 4.1.2 before we got those speeds, I would have driven the 45 minutes to Cincinnati or Lexington to get it. Or I would endure the slow speed in my area and just let it go overnight. Or is it not possible to upgrade over speeds slower than 3G/4G for some reason that I am not aware of as of yet?

---------- Post added at 12:49 PM ---------- Previous post was at 12:44 PM ----------

Does anyone here know how to get just a modem image of your phone? It seems that the different modem s between ICS and JB are causing the installation of the image of JB to an ICS phone to not allow the wifi to work. The Baseband Version Number doesn't change with the install of JB. So we need to have an image of the modem so that it can be installed to change the Baseband Version number from the ICS number to the JB number. Does anyone have any ideas? The wifi doesn't work if you go from JB to ICS either, for the same reason.

Problem solved

i couldnt do it via wifi because the wifi was not working but i resolved the issue

PROBLEM SOLVED!!!!!!!!

here is the update.zip JellyBeam 4.1.2 i437UCCMB3 for Samsung Galaxy Express i437

https://hotfile.com/dl/204284141/36ba13f/2400258.cfg.html

Rename it to update.zip and save to sdcard and enter recovery mode UP + Home + Power

then just apply the update from sdcard

The phone must be unmodified i mean no CWM and apps like that so after flashing with the stock rom

http://hotfile.com/dl/204763916/e45faeb/I437UCALI6_ATTALI6_ATT_USA_ATT_Android_4.0.4.zip.html

just update

I dont have internet at all no edge(256kb) no 3g/4g in the cellphone but i have wifi at home and now in the cellphone because i solved the problem....look in the post above :p
[Miscellaneous Android Development] caine0001:
I am glad you found the answer. But I am totally confused. First of all, how can the JB 4.1.2 be 200MB smaller than the ICS 4.0.4? But that isn't the biggest question I have. I have been under the evidently misguided notion that I got from reading other posts on this forum, that if you have rooted your phone and then install a stock recovery image of anything, like ICS 4.0.4 for example, that is doesn't remove the root. You may not have access to root because you don't have the app icon for any rooted programs, but the rooting still remains. Is that definitely wrong? If you install a stock recovery of ICS or anything else on a rooted phone does it definitely without doubt remove the rooting?

Once again congratulations. How did you find these files anyway? Most people use Sammobile. And I noticed that your ICS is smaller than the ICS on Sammobile.

And how did you discover that a configuration file was the answer if you changed it to a zip file. A config file would have been my last guess. If you can answer any of these it would sure be sweet. I would learn a lot if you don't mind.
[Miscellaneous Android Development] melkis:
All the files were in the forum but it was not easy to find. I found the rom two days ago and the update today i even remember the update post look here http://xdaforums.com/showthread.php?t=2037692&page=29

The jellybeam file is smaller because its a update not a full rom.

about the root every time i flashed the device with the full rom the cwm and root disappeared you can test it.
[Miscellaneous Android Development] caine0001:
Thank you for your immediate attention to my questions. I will try what you said. But on the subject of the rooting disappearing, after installing the new rom did you try to download Superuser or it equivalent and then try any program that needs root access like Root Checker? If you don't put Superuser or an equivalent on it, Root Checker will say no root access but if you have Superuser on and then run Root Checker it will ask for superuser permission and you can grant it. All without having to root the phone again. You just have to reinstall Superuser or something like it. I have done this before and found out it is correct. It appears you are not rooted after you install a new rom because there is no app for Root Checker to ask for permission from. But if you put something on there for it to ask, you will find that you do have root access. I have done this twice on 2 phones and found it to be true. Give it a try and see. If your phone was rooted and now you have installed a new Rom, install Superuser and run Root Checker and see if it asks for access and if you can grant it. Do this before you go thru the rooting process again. And BTW, it doesn't matter if Superuser gets installed as a system app or a user app this time. It works.

But thank you for the explanation on everything else. I am ecstatic to have this new information at my disposal.
[Miscellaneous Android Development] melkis:
the first time my device was rooted i tested it with "Reverse Tethering" and i tried to apply the update via CWM recovery and it didn't work. then i flashed the phone with the full stock rom and applied the update and it worked.

Now ive downloaded the root checker the app says "sorry! This revice does not have proper root access." but i haven't rooted the device after doing the flash and update.
[Miscellaneous Android Development] caine0001:
Have you gone on the Play Store and installed Superuser? If you do, once you install it you should see Root Checker ask for Root Access. If there is no Superuser app on your phone then Root Checker will only say Sorry!. It will not have an option to ask for root access which is there. Try it. Install Superuser and then Run Root Checker and see.

---------- Post added at 02:54 PM ---------- Previous post was at 02:48 PM ----------

So you were able to install it with the stock recovery? I thought to use update.zip off of your sdcard you had to have CWM installed. Can you clarify for me, please?
[Miscellaneous Android Development] oldnoob:
The stock recovery will only flash updat.zip files that are properly signed by AT&T/Samsung.
[Miscellaneous Android Development] melkis:
yes, i installed superuser. the device is not rooted :)

Yes with the stock recovery. the update is Official (Signed)
[Miscellaneous Android Development] caine0001:
Ok, I am officially confused. I followed your directions to a tee on my rooted i437 Express. When done I reinstalled Root Checker and it said Sorry, no root access, or whatever it says. I immediately installed Superuser from the apk I had stored on my external sdcard. Once installed I ran Root Checker and the Superuser screen came up saying Root Checker was asking for Root Access. I gave it permanent access and now I can run it and every time it says Root Access has been verified on this device. So I asked a friend of mine overseas to do the same thing. He applied the ICS you linked to and then update.zip that you linked to (the .cfg file). When he ran Root Checker he got the same results that I did. We both have root but didn't have to re-root. Why do you think that our phone is doing this when yours completely unroots? Any reasonable answer would be very satisfying for me right now. I was hoping to be able to get rid of all signs of rooting through this process.
[Miscellaneous Android Development] melkis:
i feel so dummy i was focusing only on updating the phone and solving the wifi problem, but you want your phone to be complety unrooted lol. ok lets try to find out how to do it. can you explain here what you did step by step i mean everything , how did you rooted the phone the first time, odin version, was the phone successfully updated? , can you provide the link for the superuser apk youre installing?
[Miscellaneous Android Development] caine0001:
You didn't misunderstand anything. I was wanting the wifi problem figured out. I don't need to unroot right now, but when you mentioned that you were able to do it by this method I figured it was a good thing if I ever need warranty work. Now to answer your questions before bed (I am on EST). I rooted using the motochopper method and ODIN version 3.04 after my phone had already received the OTA update to JB 4.1.2. The update was successful on first try. The Superuser that I used which was installed by the rooting method I used is located here on the Play Store: https://play.google.com/store/apps/details?id=com.koushikdutta.superuser . I saved the apk file for Superuser and Root Checker to my external sdcard and after I followed you instructions by installing the ICS 4.0.4 and then updating to 4.1.2 with the update.zip install from sdcard I then re-installed Root Checker and Superuser from my sdcard. I know it doesn't matter that I had the apk saved on my sdcard and that doing that did not make any difference. I know that is not the answer as to why I didn't unroot.

Well, I think that covers it. I hope you find something that can help me, even though this is not an emergency and I can us OTA Rootkeeper for OTA updates. I just want to get unrooted for any time I have to send my phone in for work. I am headed for bed but will be up early and bright to see if you had any idea. Thanks for even trying. I appreciate it. If you can't do it tonight I understand and can wait until you have time to look into it.
[Miscellaneous Android Development] melkis:
Sorry for the delay. i wanted to know the apk so i can test it in my phone to see if i didnt try that app but another one :laugh:, anyway still not root. the only difference i see, i didnt rooted my phone using motochopper, i did it with the method in the very fisrt page of this thread.

What i did after rooting was to use odin 3.04 > flash to ics > update via stock recovery and that's it.... not root

as last resort you should try to re-root with the method in this thread maybe?

One thing you should know: i unlocked the phone with ics and i flashed the phone again to ics so i can have it unmodified and the unlock was still there it looks like the only thing you dont want to be installed on the phone before updating the signed "update" is the CWM because your phone is still rooted and my phone was unlocked...
[Miscellaneous Android Development] caine0001:
A little more info and a question for you. I also unlocked my phone back before it updated OTA to 4.1.2. So it was unlocked and rooted when I did all this. But I didn't have CWM installed. I had returned to the stock recovery before I started your process. There may be one difference in our phones though. My phone has the file "install-recovery.sh" in the /system/etc/ folder. People getting phones now do not have this file on their phone. I don't know why it was eliminated but it was. This is the file that you have to rename or delete if you want to install CWM because if you don't it will return you to the stock recovery after you reboot. But if you rename it you can install CWM and it will stay. So to get back to the stock recovery I simply named it back to its original name and rebooted. It is a very convenient way to return to the stock recovery. Can you do me a favor and check to see if you have a file by that name in your /system/etc/ folder or you can simply check the /etc/ folder? I realize that you will have to install a filesystem explorer like Root Explorer but I would be interested to see if you have this file like me, or if it is not there like some of the phones that were sold after mine. That file doesn't answer our problem but it will tell us if there is a difference or differences in our two phones, some of which may have something to do with why I can't return to unroot. I don't think the file is hidden and I don't think you have to have a paid version of a filesystem explorer to see if you have this file or not. I would appreciate it if you could just check. If you have it, then our phones are identical and I have no answers. But if it is not there, then our phones have some differences and it might mean there is a difference we haven't discovered that is causing my unrooting problem. Thank you.

---------- Post added at 01:26 PM ---------- Previous post was at 01:24 PM ----------

Also, are you thinking if I use the rooting method in this thread that it will unroot my phone? Is that why you suggested using it? Or is there some other reason that I am missing?
[Miscellaneous Android Development] caine0001:
I also wanted to ask you about the CWM you have on your Express. It is version 6.0.3.3. Did you modify one for another phone or did you just install that version of CWM that was for another phone? If so, can you tell me which one you used so that I can give it a try. Every time I have tried official CWMs they don't work. So I was wondering if you had to modify it or if one for a certain phone works on the Express
[Miscellaneous Android Development] melkis:
i have the file

reinstall, flash, update

i downloaded the cwm provided in the first page
[Miscellaneous Android Development] caine0001:
Didn't you post pictures of your phone with CWM version 6.0.3.3? I installed the same file that is on the first page of this thread and it is version 1.0.3.0 and is OUDHS based, not official CWM.

***MY BAD**** It is another user who has posted pictures of his Express with CWM version 6.0.3.3 on his phone. He posted a photo of it installed on it. Sorry.
