[Samsung Galaxy Express SGH-I437 Questions & Answer] br0adband:
Join the crowd of Galaxy Express owners hoping that someone is able to delve into this somewhat decent device and make some magic with it (recovery, stock ROMs, custom ROMs, whatever). So far it just doesn't seem to have much interest sadly, but there are quite a few searches I've noted (right now the advanced search showed 40, yesterday when I checked there were over 70, the day before over 115, etc).

It'll either get some support or it won't - I'm considering selling mine already and I've only had it for 2+ days. My worry is that if I do decide to sell the thing that 5 minutes later someone will announce they're going to develop for it or already have some custom ROM ready, I don't know but I've had that happen in the past: get a device, nobody cared about it, sold it, then literally the same day someone starts working on it and it turns out to be a fantastically capable device for experimentation and development.

Oh well, such is the flux of Android devices and development I guess. :silly:

As for your issue(s), I upgraded mine to Jelly Bean on Saturday night and I've had issues with GPS and the CPU not downclocking as it should (sticks at about 1.1 GHz and won't go lower) so if you're still on ICS, stick with it - that's my suggestion.

(and hope someone takes an interest in the Galaxy Express, soon)

Respectfully request some help on the Express...

I noted in your sig that your Express is unlocked.What about rooting? Can you tell a very new noobie, what method can be used to root the Express? And can you tell me if it is possible to root it now AFTER I have let it update to Jellybean 4.1.2? I would really appreciate the information. I noticed your post and noted that you are the one person I have found that can hopefully tell me something about rooting the Express. I keep searching the internet and I can find nothing definitive. It seems it was an easy matter to root it when it was still on ICS, but now that I have updated I found one video of rooting an S3 with 4.1.2 and he says in the video that it should work on any Jellybean 4.1.2 device. But the rooting method used is with ODIN using a rooted img file (I looked inside the tar file). My gut tells me that I don't want to use an image file for an S3 to root my Express, but as I said, I am a noobie and maybe this is possible. Any help is greatly appreciated.
[Samsung Galaxy Express SGH-I437 Questions & Answer] br0adband:
I haven't even attempted to root it. There are several threads mentioned here (in those searches I talked about) and several methods are talked about but it doesn't appear to have a proper working root at this time. That might change if someone takes an interest in this phone but, since none of the methods I've read about are confirmed to work - one person says method A worked for them, another person says method B worked, five other people say none worked at all, etc - I'm not taking any chances on bricking this thing since it's in pristine shape and I can (hopefully) sell it. I've got it listed on craigslist at the moment actually, so... ;)

Unlocking it was cake, it uses the same method the Samsung Galaxy S3 does: enter the code to get to the hidden menu, bring up one or two of the menu options, wait 30 seconds or so, go back a step, wait a minute or so, then reboot, that's it, unlocked. Doesn't get much simpler than that, and it works with T-Mobile's recently activated (just last week) 4G LTE network here in Las Vegas without a hitch too.

But while I wouldn't mind rooting it (have a few apps that need root) I'll wait, or I'll end up selling it with the first good offer from the craigslist ad. At this point it doesn't matter I suppose, it just seems like a decent device that's getting ignored, but there could be a reason for it (some screwy new protection mechanism from Samsung, who knows, I did read that the recovery partition isn't where it should be or it's hidden, something to that effect).

Bleh... my advice for the present time: leave it alone, with ICS, unrooted, until someone potentially comes up with a breakthrough that gets things rolling.
[Samsung Galaxy Express SGH-I437 Questions & Answer] caine0001:
Unlocking and it's already updated....

Too late for ICS. I already let it update to Jellybean 4.1.2 and I really like it. It is much more responsive and accurate even with the voice-to-text feature in messaging. But, you sound very wise as far as the rooting subject goes, so I will wait for a while to see what happens. But as far as the unlocking, can you give me a link to how to do this? Or can you be more specific, please? I am such a noobie that I don't even know how to get to this "hidden" menu that you are talking about. Can you help me with more specific instructions please? I have a much better chance to sell it if it is unlocked than if it is tied to AT&T. Thank you.

Same one for all the Galaxy S3 models:

http://xdaforums.com/showthread.php?t=2023709

My suggestion: change the timer on the backlight to 5 minutes when you're doing this so it doesn't keep dropping back to sleep mode, and then get started.

Pretty simple stuff, just pay attention to the 3rd step (as soon as you choose that option, wait for at least 30-40 seconds before continuing - don't do anything, just sit there holding the phone in your hand or whatever for 30-40 seconds, then go to the next step.

When you get to the last step, definitely wait at least 60 seconds before you do a reboot of the phone (JB now offers the restart option, so restart directly from there - don't back out of any of the menus, just wait the 60+ seconds, hold Power for the menu, choose Restart and when it reboots you should be unlocked.

Just to ask, did you do any testing of the GPS in ICS? I did, and as I noted in another post in another thread, I was pulling in 22 satellites from inside my apartment in under 10 seconds and a fix in 3-5, now with JB I can't get more than 6-8 satellites in the same exact spot and it takes nearly 4 or 5 minutes to get a solid fix so I'm positive there's something going on with Jelly Bean on this device but, alas, I can't roll back to ICS now. :(
[Samsung Galaxy Express SGH-I437 Questions & Answer] caine0001:
GPS and thank you...

Both on ICS and on Jellybean it can't seem to get a good lock on any satellite, it has to go through the wifi for its location services. It even took forever to get a lock outside when I was on ICS. I will try it now on Jellybean and report back. BTW, how do you note the number of satellites that you are pulling from and how do you get the GPS to manually start. It just seems to do it randomly on my phone. I've got a navigation device (TomTom) that pulls about 16 satellites here at home but it reports it right on the screen. So, how do I force the Express to do a GPS locating and how do I find out how many satellites it is pulling from? Do I need a special app? You have really made me curious and I am learning a lot from you, so thank you. If you can just be bothered one more time to answer these questions, I will immediately test it inside and outside the house. Thank you again for all your help so far.

---------- Post added at 04:19 PM ---------- Previous post was at 03:28 PM ----------

I tested its ability to use GPS on Jellybean by turning off location by wifi. I used the yp app and it pulled an address within 30 feet of my house... When I used the AT&T Navigator Diagnostic tool I got 10 satellites outside with accuracy of 26 ft. Inside I get 5 satellites. So it works pretty good (not as good as my TomTom). Now I need to cancel that Navigator before they charge me. Hope this information helps you. Jellybean seems to give me an almost instant GPS lock, so I have to say, that's pretty good. Again, I hope this helps you in diagnosing your problems somehow. If I had more money I would upgrade to a better phone, but for the $49 I paid, this thing is pretty darned good. I understand how someone who is used to high-end phones might be disappointed, but if you want a good bang for the buck, I think the Express is a pretty good choice:good: (certainly better than my wife's IPhone 4S).
[Samsung Galaxy Express SGH-I437 Questions & Answer] br0adband:
I use GPS Status & Toolbox from Google Play more than anything else for basic GPS duties, I don't own a car anymore (gave that up years ago) so the only real purpose I have for GPS is using it with Wigle for Wi-Fi access point mapping. Having said that, I still expect GPS to work as designed so whenever I have issues it's one of the first things I notice.

I just rebooted the phone since it's been running JB for about 2 days now and should be "settled in" as Android has a tendency to do. Remarkably I just pulled in 21 satellites from inside my apartment - something it wasn't doing on Saturday night right after I did the upgrade to JB but now it is, and got a fix in a matter of seconds so, I suppose the settling in helped (?!?!?!) ;)

Mind you, that's pure GPS in the screenshot below: no Wi-Fi assistance, no location awareness, and no carrier assistance either, everything is disabled except the GPS itself so, yeah, I'm somewhat satisfied now since it seems to be working pretty much as well as it did on ICS the other day before the JB upgrade.

Anyway, when I enabled the Power Saving mode, the CPU finally started clocking itself up and down as expected so I suppose that too is also now working as designed, we'll see what happens. So far so good is all I can say at the moment.

Here is a copy of the stock recovery. Have fun =)

This is not a flashable zip. It only a copy of the mmcblk0p18 (Recovery) partition from ICS 4.0.4 of the Samsung Galaxy Express I437

Awesome thank you...now...

I'm a newb at stock recoveries, unless Theyve already been Made, so pay no attention If my next question seems dumb but what do I do with it now? How do I create a flashable recovery from that?

I have managed to get root on this device well at least with 4.0.4 ICS, that part was relatively easy with unlock root and It let you unlock root without paying for It lol and I agree I hope someone takes interest in this device soon when you compare it to the s3 the specs arent that far apart lol

The partition layouts are identical, but the kernels and images are different.
[Samsung Galaxy Express SGH-I437 Questions & Answer] invert_nexus:
Hopefully, we can get somebody with stock ics to do a factory reset then a system dump. I tried flashing my system dump with odin and it seemedto be trying to flash something to boot thus invoking our cursed locked bootloader. I don't know why it would try flashing to boot as it should have been only the /system partition. Maybe something to do with initramfs

? I'm hoping a system dump performed after factory reset might have different results

Now, since we cant flash a zimage that means we're stuck with jb kernel. Would that be an issue, I wonder? If we had jb kernel (and initramfs) with ics /system?

Another thing would be for a rooted ics to use ota rootkeeper for update, then system dump.

Factory reset, root, ota rootkeeper, update, system dump.

If not, then cwm and an insecure kernel would be our best bet. Although we would need the initramfs from the jb zimage. Which we can't get without root...

Sigh.

As to the recovery image. You'll need to use odin 3.07. I don't have a link handy. Also, the file must be prepared in a certain way. I have one at hone. Can upload later.
[Samsung Galaxy Express SGH-I437 Questions & Answer] invert_nexus:
Of course, you can make your own odin img as follows:

Either in linux or in an android terminal emulator:

First of all, cd to the directory the recovery image is stored.

E.g.

cd /mnt/extSdCard

Then:

tar -c recovery.img > recovery.tar

md5sum -t recovery.tar >> recovery.tar

mv recovery.tar recovery.tar.md5

Note: rename original recovery image to recovery.img. Not sure exactly how odin determines what goes whereand suspect it might be the name.

Easy.

Same procedure for kernel and system, by the way. zimage and factoryfs.rfs respectively.

Alright thanks to BlindArtisan and invert_nexus i was able to create and successfully flash the stock recovery back onto the express. I'll post it here for anyone who might need it :victory: this does not have CWM on it but i'm currently trying to figure that out also :confused: I also have a copy of the update to JB that i'm going to attempt to use to get the phone to allow me to update and I'm going to use OTA RootKeeper to see root access will stay.

Once again thanks to everyone here for their expertise and knowledge hopefully we can get the attention of some people to get the galaxy express ball rolling lol

ICS vs JB GPS

I was able to do side by side testing of ICS vs JB since mine got upgraded & my wife's didn't and your GPS observation seems spot on. Neither of us had ever used GPS so 1st thing I noticed was mine with JB it took about 10 minutes to get a lock where hers took about 30 seconds. Keep in mind these phones were side by side. Granted indoors but near a window but either way they were next to each other so should get the same signal/sats. I left them both searching for sats for about 1/2 hr then swapped spots & let them go another 1/2 hr. Even after leaving them for awhile the JB one definitely finds less sats & takes longer to lock. A very strange thing to note is for some reason the compasses show completely different direction but not sure why. Funny thing is neither is right but ICS is closer & JB is WAYY off.

I attached pic of them side by side after same amount of time searching and also a video showing them sync. Granted time difference is negligible now, the # of sats is definitely lower for JB. (JB on left & ICS on right. Can see the upgrade nag at the top as it was postponed.)

Hopefully poor GPS doesn't plague this phone if JB is being forced on us.

Bill

EDIT: Apologies to OP, this thread came up searching to compare ICS vs JB & I didn't pay attention I was OT replying. While already OT I'll add a few more observations about JB vs ICS. :D JB seems to be using 171MB more memory than ICS comparing mine to my wife's with mine @ 494MB used & my wife's @ 323MB. (Some apps are the same, just larger, but there are a few new ones like Simple Alarm Clock 3.5MB, PageBuddyNotiSvc 3.0MB & Stock Daemon(EUR 4.2MB to name a few but many other crapware's I'd love to kill. (I can kill some of them temporarily but they come back) ATT Software Update is using 10MB, Media Hub 4.6MB, S Suggest 3.9MB, AT&T Hot Spots 3.0MB and a few i'm not sure on like Synchonize 5.0MB S Voice 6.3MB com.sec.phone 2.7MB.) They took away the Mobile Data button on the drop-down menu! The new dialer is FUGLY! (Granted I hate the stock dialer because it's so hard to dial & find people so I use Dialer One but still WOW what is up with the white dialer.) On both rom's I miss the Power widget. :( Really need to get this this ROOTED ASAP to kill some of that crap.

JODIN can't find the PIT

Hey there, XDA people. I'm a noob that managed to get himself into a bind (imagine that). I bought the SGH-i437 from Cricket.

I successfully rooted the phone and attempted several varieties of backups - each of dubious utility since I had no idea what I was doing. I can't use them now, for reasons unclear to me, but certainly due to user error. However, I was on a path, so I went on and flashed CM11-20140829NIGHTLY. It's been working very, very well.

I would have been trouble free, in the clear and happy, but I moved to London and had to change my Cricket service to a local carrier. To do that, I have to unlock the SIM. I have an unlock code. When I go to unlock it, it doesn't work because in CM11 you can't access the debugging screen from the dial pad (those were the instructions sent to me). The kind people helping me unlock my phone suggested I flash back to stock ROM. Then, they tell me, I can follow the instructions. This is where my story stops.

I have a macbook, so I'm using JODIN, and I've installed heimdall on my macbook. I connect, I put the .tar file that I found on the internets into PDA and click start. J ODIN says it needs to find me a PIT file, and it tries but doesn't manage to find one. http: / / pastebin . com / 5DpJjyk8 - Hopefully that will link to the incredible string of code and whatnot generated by JODIN. I put in spaces because XDA won't let me post URLs.

I'm not sure what I need to do, now. Am I supposed to be out there looking for a mysterious PIT file, or doing something different with JODIN? I eagerly await returning to the crappy stock ROM, unlocking the SIM, then returning to the sweet blissful CM11. Please, please can you help me?
