Hello fellow XDA friends.

I can't get my cpu detect my phone in diag mode.

My phone will enter diag mode (thru the ##3424#) but my computer won't detect it as a port (in device manager)

I verified that it wasn't the USB cable or my drivers by connecting another phone in diag mode (s3)

Any assistance would be appreciated.

ps I tried the 9090 trick no luck

Alright, so I'm fairly lost as far as rooting and everything goes on the latest firmware of the GS4.

I came from the OG Evo which I heavily modified, and when I first got my S4 I rooted it and installed a custom ROM. Over a few weeks the ROM basically crapped out on me, so I went back to complete stock. I took all updates since then and am now on NAE with everything being at the factory settings.

I want to try out Cyanogenmod again, but I do have some questions. The first is, could I use CM's tool to install the ROM? Also, would that trip any flags? I'm not entirely sure how you trip Knox and or any other security features that Samsung has, but I would like to know.

Also, is there a better method of installing Cyanogenmod on my device like going through ODIN, or would that be better for installing things other than Cyanogenmod? Thanks everyone.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] snahaw0:
To flash a ROM, you need ROOT and a custom recovery (TWRP, Phils, or CWM.) To get ROOT, you will have to use ODIN, which will trip KNOX. Personally, I don't care about tripping it as I am out of warranty anyway and would have to make an insurance claim on a hardware failure, but I am more likely to break it than an actual hardware failure.

Phone no longer responds to computer. Connect usb port and the only thing that happens is that is phone asks me to choose between media connection and camera connection and on computer it just says that device installation of MTP failed. I've tried reinstallation of kies and samsung usb driver and it does nothing. Also tried uninstalling all the usb host drivers and restarting and that did nothing.

How to revert to Stock from CM11 M7???

Hi all.

Be gentle please, NOOB here!

With all the hype about the new CM11 M7 I went ahead and installed it on my stock Sprint Galaxy S4.

While it works OK (no problems etc) I just REALLY don't like it and want to revert back to stock.

I thought it would be simple but I have read a few places that I'd need to revert to 4.3 first or brick the phone if I tried to go directly to stock 4.4.

Can some kind soul please step me through (using little words;) what I should do to revert to stock and NOT brick my phone?

Thanks MUCHO in advance for any help you can offer!!!

I know my mom had same problem, i told her to try another cord, don't know if trying another cord will help, but that is what she did and she was able to get to everything on her phone. Maybe also, if you have another computer to try on to see if it shows up, or if you have another phone to check to see if that one will show up on your computer. Just some suggestions probably won't help but thought I would give my 2 cents. I'm a noobie myself, so sorry it don't help you.

Can't access recovery menu

OK,

So I have a L720 S4, and have used odin to install CF-Auto-Root

I installed MF9ModemOnly

I then installed Philz_touch_6.15.6

My intent is/was to install the negalite wonderom.

When I try and access the recovery menu (volume up, home button, power button), I get an error "system software not authorized by samsung has been found on your phone", and in the top left corner in red letters it says "Secure Fail: Kernel"

I can boot my phone normally just phone, and access the download menu, I just cannot get into recovery to continue with this process.

Thank you for any help!

Status Update

Ok,

So after trying to get a factory rom back on the phone, it says that it fails. If I run the philz recovery, I can get the phone to boot, slowly, but it does. But it says the phone is not rooted. I tried to run the CF-Auto-Root through Odin, and it will give me a pass, but then I get a message when trying to boot or access the recovery menu that there is unauthorized software on the phone, etc. At this point I can only go into the download mode. If I run philz recovery again I can get the phone to come back on, but then I'm back at square one again.

Any help would be great!

Did you let odin reboot?

IF SO turn it off and manually reboot whe it says pass by holding the power button down
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
It failed because you are installing the wrong firmware, you can't install older firmware than what your bootloader is. You are most likely on the knox bootloader so you need to install the NAE stock tar to recover your phone back to stock. Then you can reroot with cf autoroot if you want.

I'm having the same problem as everyone else on NAE stock room when I try to root and then apply the HotSpot mod every app that updates or installs crashes repeatedly rendering the phone unuseable.

I am attempting to flash the stock NAE rom using Odin. I hear I'm not supposed to allow autoreboot so I will uncheck that. My question is when I flash the NAE.tar file will I lose all my text messages and attachments? I can't back them up because the backup apps crash.

What procedure did you use to factory reset your phone. I have only rooted and done the hotspot mod using ODIN. Is that all you have done. I have downloaded the NAE.tar rom. I assume I just flash it and reboot the phone.

ROM OS Version: 4.3.x Jellybean

ROM Kernel: Linux 3.4.x

Since I've done the OTA update to NAE and would thus have the NAE Firmware, would I be able to successfully flash this ROM? It seems to be saying the MK2 Firmware is required.

Hi, I got my s4 recently as a gift from a friend. He had rooted it, installed custom recovery(cwm) and flashed liquidsmooth rom. I have been reading on the s4 because I would like to change roms and want to understand everything before I do it. Something that caught my attention was that the baseband is L720TVPUBNAF but my model is an SPH-L720. The thing is, that I read in this thread that the L720TVPUBNAF baseband belongs to the SPH-L720T(triband version). I am guessing that my friend flashed a wrong file from the Triband model. Or do I have the triband model?. Will this cause problems when I flash roms?

see pic for info.

update: Found the anwswer. I put my phone in download mode and it listed my model as sph-l720T.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] markmc00:
WOW! That was close!

Ok, I almost realized my worst nightmare. Not that I messed up my phone (which I did, temporarily), but that the wife was right that I was going to mess up my phone. :eek:

I decided to flash the NAE based Negalite Wonderom to avoid any problems with old firmware, etc. Everything worked perfectly and I liked the ROM, but I realized I didn't have the time right now to get the phone set back up and configured like I wanted. So I decided to restore the nandroid backup I had dutifully made before doing the flash.

That's when things didn't go so well. The restore appeared to work and the phone booted up, but I had no network data or phone service. So I tried wiping cache's and restoring again, with the same result.

I started looking around and found in settings that a lot of things were "unknown" like PRL version, MEID, IMEI, Software version, SIM serial, Phone number, etc. So I figured I somehow hosed the efs partition. So I restored it from a backup (actually two different backups) that I had made, but it didn't fix the problem.

Spent several hours scouring the forums, but found nothing that really addressed this specific issue. So I began downloading a stock NAE ROM to flash hoping it may fix the problem. But while it was downloading, I happened to remember that after flashing the Negalite ROM, I noticed that Philz Recovery had the same blue customization that is characteristic of the Negalite ROM (and I think I remember reading something about the ROM further customizing Philz recovery).

I decided to odin the philz recovery that I had originally used to make the nandroid backup. After that, I restored the recovery file again, and everything is back to normal!

I'm a noob at this, but I'm guessing the the Negalite install may have modified Philz recovery, maybe to a different version which wasn't completely campatible with the recovery file?

I'm only posting this in hopes that it may help someone else recover in a similar situation. This may be a well know issue and, if it is, I apologize...but I am a noob.

I'm not faulting the developer at all. I have the greatest respect for, and am in awe of, the guys who have the technical expertise to develop this stuff. I probably missed something in the post that stated which recovery version to use. I just loaded the latest version available.

Thanks for listening!

I am an iPhone user and recently had the joy of finally getting a galaxy s4. I have already rooted my phone and flashed to the newest custom rim with 4.4.3 from Droiddawg. I am using freedom pop on sprint and the only way to get LTE is to do a PRL/profile update.

I've Fallen and I Can't Get Up

I'm running 4.4.2 on my SPH-L720 Sprint Galaxy S4, rooted with Cyanogenmod 11. I wanted to ensure I could root the phone before I put service on it (it's a hand-me-down), and only now have I discovered that I need to be running TouchWiz to activate Sprint's phone plan. Kies 3 won't recognize my phone, and I'm on a Mac, with the Cyanogenmod one-click installer – don't totally know what I'm doing.

Please help me restore my phone to TouchWiz 4.4.2, Obi-Wan, while keeping it rooted. YOU'RE MY ONLY HOPE
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
You need a TouchWiz ROM to do PRL updates. Just like you need a Sense ROM to do this on an HTC device. What this means is, procedure wise -

1) Backup your current setup via nandroid

2) Wipe device, install TW ROM, boot it, update PRL and profile (WTH is PTL?)

3) Boot back to recovery / wipe / restore current setup from nandroid

That is the PRL Update Shuffle, brother! :cool: :eek:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Molokinhu:
Hi Jerry,

I did what you suggested.

1) rebooted into recovery mode with twrp, did a full backup or my os running 4.4.3

2)I did a full wipe, followed by a factory reset wipe inside twrp, installed stock TouchWiz backup I had, rebooted, updated prl / profile

3) rebooted into recovery mode with twrp, restored the backup of my previous system with 4.4.3. Rebooted into the system and nothing really changed... I still only get 3G, but on TouchWiz I get LTE and 4G.

Did I do something wrong?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
No, sure sounds like you did it properly. If you have 4G and/or LTE on TW, I'd post about this in the thread for the ROM you're using. It's obviously not your hardware, which leaves the software. It may be something as simple as a configuration issue.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] churchey360:
It could be your APNs or just a week signal. AOSP won't get as strong of connection like with a stock ROM. Also I think it could be your APN because you use freedom pop on sprint.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] WarAxe:

Suppress system updates from Sprint?

I recently got my S4 after enjoying my S3 for years.

This time around, I'm getting into ROMs early. I wanted one with WiFi Toggle, so I flashed "stock(ish)v06", which apparently is based on Android 4.3. I also have Philz recovery installed.

This morning, I see "System update downloaded. Touch to install."

1) I don't want to do this, right?

2) How do I suppress these downloads, prompts to install, etc.?

3) Is there a better ROM with Wifi Toggle (probably just personal preference) that stays up to date with the most recent builds, etc.? Or does this one and I got it from the wrong thread?

Load Cyanogenmod from Stock NAE

As the title says, I was wondering if this was possible? I am working on a friend's Sprint Galaxy S4 and he has stock, unrooted NAE on his phone. I've had CM11 on my phone for quite a while and he wanted the same on his. So I did the normal chainfire root and loaded a recovery with no problem. I booted after I did this to verify everything was OK. I tried to install the latest nightly and it hung on reboot at the CM boot screen. I tried a nightly a couple nights back and the last snapshot and got the same thing. Is it even possible to install ANY CM11 on a phone that was on stock NAE?
