Did as you asked. . .

I followed your instructions and cut and pasted the HiAPN from data/app to system/app, using root explorer. Tried to open APP. I got a message saying the HiAPN stopped working. So I moved it back. Looked online and found someone who did it using ES File explorer, so I used this one instead, the version I had did not match the same one he had so the steps were not the same. But the instructions were the same regarding what I had just done with the root explorer with the only exception being that in the Setting of the ES File explorer I selected Root Explorer I set to ON, and then I backed up the settings as suggested by the youtuber. And mounted it with the auto settings it selected for me. None of that mattered because it was the same steps - copy and paste from there. And I tried to open HiAPN and got the same error message. Annoyed I decided I would try something else. I went into ES File explorer, found the APK file again, and this time clicked on it inside the System folder, so it would launch straight from ES File explorer. The APP opened. I selected - "Click to Auto select APN's" since this option made the most sense. It asked me to download an update. I accepted. It said something in a language that I couldn't understand, but the other option that I could read said "Cancel" so I clicked the other one. At first it kept coming back saying that there was an error in updating. At some point the phone asked me overwrite it. Which I agreed. The phone rebooted, and tried one more time. This time it worked. I selected "Click to Auto select APN's" - and the update stuck. I turned off my WIFI - and BAM! 3G!!!!!

My concern now is - do I always need to have this app running to be able to get 3G? Or is it something I can now stop from running and the settings will stick?

Help

What I want to do is install a stock non rooted rom, kernel, and recovery. I am not sure how to change recovery to stock either is it like flashing a rom? Please give me some links for these I can't seem to find them, besides the stock kernel I found that.

My phone is about 95% broken.

Before, every rom/kernel combination would randomly restart, it was my phone it self I believe.

I went to a stock rooted rom, but then it restarted, and my lock screen worked, yet my home screen was black all i could do was slide my status bar down.

After that i restarted my self and then it got stock forever on the screen where it says Samsung galaxy s4.

The 5% working part is my recovery, for the most part.

I keep having to do a full wipe, not just system wipe otherwise it says error unable to mount preload or i/o or a few other things, I have to system wipe before every rom attempt.

I tried several popular roms such as sacs and triforce and a few other roms and all the kernels also.

The phone will turn on, work for a little normally, then crash again and go into the infinite loading screen where is simply says galaxy s4.

This phone is only 3 months old.

I need links to files I need, and if i am forgetting to change anything back to stock please let me know. Thank you.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
You need to download the latest complete firmware from here: http://www.sammobile.com/firmwares/ and install it via odin. This will return your phone to completely stock everything. I would advise doing a factory reset in recovery before using odin, and then doing a factory reset in the stock recovery after you install with odin. Your phone will be completely stock and unrooted after this process. If you are still having problems after this than it is probably hardware related and not software related.

Mobile Data Connection Error

So I'm not 100% sure what went wrong. The only things I have done was root according to QBKing's video using TWRP Recovery and loading the Hotspot Hack onto my phone. After this, I've noticed that there's been weird disconnects from both 3G and 4G LTE on my device. Sometimes I'll get the error message: "Unable to Establish a Wireless Data Connection" (screenshot attached).

I can update the PRL and Profile which seems to fix this, but this keeps occurring. I haven't done anything else to the system either. Could anyone please advise?

I'm sure this has been asked but I'm not savvy enough to find it via search. Not sure what terms to use. Didn't have any luck. Apologies if it's all over the place here.

I picked up the S4 a few weeks ago. I rooted within 6 hours of getting it. Now of course it's all set up the way I like it with data all over the place.

A few days later I got the message

System update downloaded Touch to install

Crap. So I secure a few things. Take some pictures of the way I have things set up on the home screens. Move some stuff to the sd card. etc.

I tap to install thinking I'm just going to have to reroot, and maybe wipe, afterwards. Nothing happens. Nothing installs. I still get that message when I restart the device.

I don't know what releveant information is needed to get me up to date but I think I'm at least 2 releases behind.

Android version 4.2.2

Baseband version L720VPUAMDC

Kernel Version 3.4.0-442222

se.infra@SEP-136#1

Wed Apr 10 16:22:56 KST 2013

Build Number JDQ39.L720VPUAMDC

Happy to add info, start a new thread, delete this post, but any help will be appreciated...

I guess what I'm looking for is the easiest and or best route to getting up to date and stay rooted.

Thanks.

First of all im glad you didnt started a new thread because believe me this has been answered so many times. But to answer your question. When you root your device, add a custom recovery and add mods to the device you cant accept the new updates any longer so you got to unroot your device and set it back to stock.

http://xdaforums.com/showthread.php?t=2375523

The link above is a link for the most current update for our phone. You can install it via odin or you can also install it the update via kies. Before doing so of you have any personal stuff in internal memory not sd card then save them first later do a factory reset. Put your phone in download mode and install new update and you should be running the newest firmware stock. And yes you can still root and add mods to it. If you need help or so just come back and post.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
Yes, you are 2 releases behind but if you are rooted and have modified any system files, removed bloat, or have a custom recovery installed the update will fail. The only way for you to upgrade to the latest firmware is to return to complete stock or if rooted and on a custom recovery install one of the stock rooted mf9 roms in the development section. The best way is to install the complete mf9 firmware with odin and then re-root with cf-autoroot. This method will make sure that all of the radios, kernel and firmware get updated properly and will be the most trouble free method.

LTE not working after google play rom port

OK guys i thired looking for this first but didnt have any luck and what I did find is a little beyond my understanding. So I rooted my s4 using odin and TWRP recovery made a nand backup and flashed carbon and CM 10.1.2. Both roms worked great except for no IR support. Found a rom that would support it out of the box which is the Google play edition rom. Found the port for sprint loaded it and it worked except for one small problem. 4g LTE would not work. Didnt think it was that big of a deal however i didnt find a really good ir program that I liked. Wiped system Davlik Cache and date and loaded carbon and I cannot connect to LTE no matter where I am and i am in a 4g area. I cannot for the life of me figure out why I can nolonger connect to lte. If you need any more information or know what it is that is causing this problem please help!!!

CM 10.2 [Nightly] Boot Issues / Proper Data Wiping (CWM)

Since I'm afraid God will knock on my front door with a sawed-off 12 gauge if I post a new thread for this (which I'm sure I wouldn't be able to do if I tried), I think this is the safest place to ask about this...

Part 1)

I just got into the android world like 4 days ago, and instantly found info about rooting, recoveries, custom ROMs, etc. So, I took my shiny new Galaxy S 4 (Sprint) phone, and installed CWM and TriForce ROM on that bad boy. Then I found CyanogenMod. Holy crap- awesome!

Everything is working fine (i think) except the phone hangs on the boot screen (S4 logo) about 40% of the time. I started with the 9/8 nightly build, and it was hanging on boot. It sounded like the issue was resolved with the 9/9 build- so I installed it. It is still freezing on boot.

Why I'm asking this here (rather than spying on the developer's thread for the nightlies) is because I'm not positive if it is the CM that is hanging, or something else (possibly).

I guess what I am asking is: How can I determine if the hang-on-boot thing is the OS or not?

Part 2)

I have flashed my phone about 4 times since I got it a few days ago. I don't know enough about the file structures of these phones to know if the files that my previous ROM(s) used were ever deleted when I re-flashed the new ROMs.

My understanding was that doing a "wipe data / factory reset" via CWM would remove the files from the previous ROM so the new ROM will install "cleanly". If that's the case, then why does the phone boot after I do that if I don't flash another ROM? I still don't know what the Dalvik cache (spelling?) is being wiped when I do the above mentioned wipe. I've seen advice recommending wiping the Dalvik cache, system, data, cache, etc.

So, what is the proper way to "format" your phone so that the ROM you are flashing is the only thing on your phone's drive?

I hope I'm not violating any forum rules, or stepping on anyone's toes by asking this stuff here... Anyways...Thank you in advance for any advice!

[MENTION=5425030]Blackout271[/MENTION] I wipe dalvik, system, data, cache all multiple times then format/wipe internal card. Just make sure you have a working nandroid and backup/move anything off internal storage before you wipe it because it will be gone after the wipe. Also make sure your saving your nandroid and the rom your going to flash and gapps on extSdCard so you can just flash after the wipe. Don't want to wipe those.

Any thoughts on this one? I'm having similar issues. I'm on the mf9 update and using TWRP. The only ROM I've been able to sucessfully flash was the Google ROM, all others error out during the flash process. I've redownloaded the ROMs and still nothing. I had a Droid Bionic and flashed ROMs constantly on it without issues. Thanks!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] HPferoxCraft:
What version of twrp? I had issues and then flashed back to 2.5.0.2 and it's been smooth ever since. Are you doing full wipes before flashing the rom? Fails in the middle of installation or right off the bat? Mabel a bad download, do you DL to your PC or phone?

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dburger66:
I have 2.6.0.0., how do you uninstall to flash backwards? Yes, I do a full wipe and the ROM fails in mid install. I normally download to PC then copy to my phone, it's faster that way. Thanks!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] HPferoxCraft:
Good possibility that could be an issue. Search for and download twrp 2.5.0.2, reboot to your twrp recovery and install the 2.5.0.2 zip. It will replace the 2.6.0.0. Maybe reboot to recovery again to be safe and then try the rom. I'd also recommend an md5 checker to make sure the files match when putting a copy on sdcard from PC.

2.6.0.0 was really buggy on our phones do I hope this helps. If it still fails maybe try a different sdcard.

hi i recently rooted a sprint s4 and it was working but then i wanted to sim unlock it. So i first changed the baseband to try to be able to get it sim unlocked. But that didn't work so then i put a custom aosp (i think it was cyanogemod on it) and then i realized that by doing that i wouldn't be allowed to sim unlock it following the methods on xda forum. So i tried to then flash a stock samsung rom and then thats when an error occured and now I am soft bricked. I wanted to know how can i get it back to working and then sim unlock it so i can have my grandma use it as a phone on tmobile network.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] parrots_:
So I have a 1-file firmware for my S4, which I'm assuming is supposed to be the PDA / AP file. If I were to use an older version of Magisk, so that it still supported Android 5.0.1, could I still just patch the file and flash the patched PDA to the phone? Or is there a difference when doing it with Android 5?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BlackoutSTi:
Thanks for the confirmation! It just seemed like performing a wipe of everything that CWM allowed me to didn't get everything. The reason I thought this was because I was noticing (in Titanium Backup) that many apps had a '1' or '2' after their title, and it seem to increase each time I flashed a new ROM to the device. I took this as the equivalent of a '(1)' or '(2)' after a Windows file name (that is saying there is more than 1 file with the same name). Is there a link anywhere that I could see a snapshot of the filesystem of android / CyanogenMod? I'll keep looking but, so far, I have found nothing...
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] HPferoxCraft:
I believe that will be how many backups of that app you have saved. Hopefully saved to extSdCard. You can change in the TB preferences how many backups of each app to have, mines at 1. I don't think you'll have 2 versions of the app running on the phone, so if your saving backups off the phone this shouldn't be a huge deal.

You can use any root browsers to view system files, es file explorer, rom toolbox etc..

Edit: hmm tried to replicate what you were seeing in TB, but couldn't. I swore that was how TB showed multiple backups but it just states how many under the app title. So maybe you are right.

Personally I would format internal data a couple times to make sure everything was gone (have a working nandroid first in case), but that's me.

Sent from my SPH-L720
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] BlackoutSTi:
I'm not able to recreate it either... I'm not sure what I did to make that happen. It could have been something that the developer of TriForce ROM did with the names of the included apps. I think that was the ROM I was using when I noticed the odd names.

On another note - I used to have data in /storage/emulated. There doesn't appear to be anything in there any longer? I had /storage/emulated/0 and /storage/emulated/legacy before. And inside each one of those was many directories. What is normally stored in /emulated?

Hello,

My s4 is stock. Is there a way to adjust the font size on the messaging app without using the volume control option? So frequently I get a text and realize my volume is on, go to turn it down only to later realize nothing happened because I was reducing an already fully reduced font size instead of the volume. If you turn off the option to adjust using the volume control, the font gets huge even if it was on small before you turned the option off.

Use a 3rd party app such as handcent or go sms. Should solve your problem. I looked, don't see an option to do it in the stock app.

Very confused lol. I'm using TWRP, but again, it's booting into generic Android Recovery even when using the app. So It seems like I'm just reflashing the stock ROM over and over.

if you are using generic/stock recovery then you are not using TWRP.

If you are rooted then..

Download goomanger from the playstore and then install TWRP. Watch this

Also please take some time to read through the stickies and how to's. ESPECIALLY if you you are going to install a custom ROM - follow the developer's instructions.
