Same here. But it stuck and works great. My LTE signal is significantly better using Network Signal App.

But now my Wi-Fi is broke, oh well knew that going in. Back to MF9.
[Sprint Samsung Galaxy S 4 Android Development] masterosok:
I found the answer to my question.... Everything worked flawlessly so for. I did not flash the wifi fix and so far wifi is working at my work.

I do have another question... my wifi connections are not longer being remembered after a reboot. Does the wifi fix address that or just inability to connect to wifi networks. I can connect to them it just forces me to re-enter the password after each restart.
[Sprint Samsung Galaxy S 4 Android Development] vegasmach1:
Quick update on my no Wi-Fi issue. Updated the kernel as recommended in post #1 and worked great. Sprint is upgrading a tower right near me and they just lit it up. I just pulled 32 down! Yeah that some serious speed.
[Sprint Samsung Galaxy S 4 Android Development] Danieliyo:
Hi, I followed this guide and everything went good and smooth first time.Everything is working.But I keep getting a pop up message saying SECURITY INFORMATION- "The device has detected an application attempting to perform actions that are not permitted. It is recommended that you restart you device"

Any idea what the problem could be? If anybody can help me I would appreciate it.

Thanks

Knox. Use the knox removal script or uninstall with titanium. Profit.
[Sprint Samsung Galaxy S 4 Android Development] Mship:
So I have come across an interesting issue that I have never had on any android phone before.

I followed the guide and had no issues upgrade from MF9, until I woke up in the morning for the second night with a phone that is fully charged, but frozen.

I could not wake it so I hard to do a rest by holding the power button.

This is the second night in a row. This made my morning alarm not go off.

When I go to bed to I will leave the phone off the charger to see if that is the reason for the freezing.
[Sprint Samsung Galaxy S 4 Android Development] masterosok:
Which network signal app are you using?
[Sprint Samsung Galaxy S 4 Android Development] ryskiJ:
I'm having the same issue,I've also noticed the hand off between AP's isn't stable. I can't connect to any network that required EAP. Wondering if anyone else is having this issue? Anyone find a solution?
[Sprint Samsung Galaxy S 4 Android Development] optimummind:
On the first boot after the flash, I had to wait almost 10 mins before I got to the homescreen. I just put the phone aside & played around with my N5 while waiting, LOL~
[Sprint Samsung Galaxy S 4 Android Development] MoHoGalore:
Half way there - take out going into the system after flash. I went straight to recovery after a battery pull, wouldn't stick. So, I unchecked auto reboot and when it passed, I just held the key combo until it rebooted.. 12-15 seconds.. it stuck. And I was flashing Garwynn's CWM.

:edit: Battery pull was not on system boot. After flash with no auto reboot as well.. I cant explain why I wouldn't stick nor did I get a log. (As Shabby reminded me I should have done)
[Sprint Samsung Galaxy S 4 Android Development] crawrj:
Can you duplicate this problem easily? If so, mind trying it with twrp? I only ask because I went back and forth between MDC and MDL at least 30 times during all of my work when MDL dropped and I never once had this problem.
[Sprint Samsung Galaxy S 4 Android Development] J_Uneek:
Yes stock MDL but I always go straight into recovery after the flash. Pop the battery back in and then vol up and power.

---------- Post added at 03:53 PM ---------- Previous post was at 03:49 PM ----------

So you just held volume up and power as soon as "Passed" showed? Was this all while still connected to the computer?
[Sprint Samsung Galaxy S 4 Android Development] MoHoGalore:
I can when I get home in a few hours. (Currently on CM.)

Unplug usb. (That's a habbit) Phone will still be in Odin mode. Just hold vol up and power. Don't let go of vol up. If the screen turns off and you don't get the reboot, keep your finger on vol up, release power and press again. (Just did it again to get a count and it took 15 seconds)
[Sprint Samsung Galaxy S 4 Android Development] J_Uneek:
This worked... Thanks
[Sprint Samsung Galaxy S 4 Android Development] ACoolGuy:
As a response to the whole how to get into recovery thing, On all my devices, I have never had to hold power. Volume Up held during a reboot should suffice to get into recovery. For instance, I Odin with auto-reboot. As soon as its done flashing, I unplug USB and then hold Volume UP while its booting(before the vibration) and viola, Recovery. Same for Download Mode. Not sure why power is really needed. If you are holding the volume up(recovery), or volume down(download) before the vibration of the boot/reboot, it will take you to where you want to go. Just a heads up for everyone. The only way the power button gets involved is: from a powered down state, you must hold power to boot the phone.
[Sprint Samsung Galaxy S 4 Android Development] Cloaker:
Anyone else having data issues and getting "preparing network" constantly?
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Thanks! OP updated!
[Sprint Samsung Galaxy S 4 Android Development] Tahde:
I did this twice yesterday with no problems. Always stuck. Uncheck reboot. After it was finished, I just unplugged usb from device and I went right to recovery. I used Odin 3.07.

[Sprint Samsung Galaxy S 4 Android Development] MoHoGalore:
Providing that auto reboot is checked. I uncheck it so I'm not trying to catch it (plus I can get up to get a beer ;))

Ill have to remember this. Habits are hard to break. :beer:
[Sprint Samsung Galaxy S 4 Android Development] mich0020:
I did the exact same thing with the same result. Uggh. Didn't have a nandroid. Took some troubleshooting, but my remedy was to start at square one and flash back to factory settings and MDC version. Two tries to get the recovery to stick. I powered down immediately when Pass popped up on Odin, pulled the cord and the battery. Happy to say everything is working fine now.
[Sprint Samsung Galaxy S 4 Android Development] cheddaface:
So is this still the only method to get the Latest MDL ? I cant risk loosing hotspot (work related issues)
[Sprint Samsung Galaxy S 4 Android Development] mich0020:
My hotspot is working. Just make sure you download flash the new MDL hotspot rather than the MDC version (like i did). Otherwise you will have issues getting stuck on the yellow sprint boot up screen....
[Sprint Samsung Galaxy S 4 Android Development] fiddy619:
All went well, I used ACoolGuy's method...

A quick question tho, is there a free app to freeze apps so i can get around the seandroid message???

This is for my son's phone btw...
[Sprint Samsung Galaxy S 4 Android Development] ACoolGuy:
App Quarantine in the market.
[Sprint Samsung Galaxy S 4 Android Development] Powerbird101:
"Device detected an application attempting unpermitted access" anyone getting this error like me? I have already reflashed the kernel and root file and everything is sticking as it should but this annoying thing keeps popping up. Someone in another thread stated it had to do with SEandroid but it seems this is a hit or miss issue. I have not romed the phone yet but have tried to resolve it unsuccessfully with a dalvik/cache wipe and that did nothing. This had been asked on this thread once but it was overlooked and never answered. Any suggestions?
[Sprint Samsung Galaxy S 4 Android Development] Grommish:
Freeze SEAndroid. The nag screen comes from root and kernel changes.
[Sprint Samsung Galaxy S 4 Android Development] wojo797:
restored stock , updated and the update didnt take.. the build changed but everything else stayed mdc. anyone else have this issue? also it broke my wifi..i cannot reconnect it
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Read above quote. Seems like your just have to do it over again. Restore full stock MDC with no root and data wipe.
[Sprint Samsung Galaxy S 4 Android Development] wojo797:
tried it 3x already same result...in the process of the fourth now....

update 4th time took...now just cannot get root
[Sprint Samsung Galaxy S 4 Android Development] Skyh123:
Just tried this twice with mobile Odin but no luck, it seems like everything went through have the android updates, and did just as described but still on MF9. I know the main difference is that I was already on 4.3 but other than that not sure. Still have great signal so will try on the PC when I'm able to and will be fine till then. Thanks for the info though.
[Sprint Samsung Galaxy S 4 Android Development] Jim M:

Up and running 4.3 MJA with the ktoonsez Kernel. No force closures, WiFi works, sound works, videos work, Knox did not trip.

Why do I need kt kernel can I just use stock mja kernel.
[Sprint Samsung Galaxy S 4 Android Development] efipaul:
I got everything to work ok, but I'm still having a WiFi problem. It connects fine, shows as connected, but after some time (anywhere from 5-45 minutes) it stops sending and receiving data. Still connected to the network, still showing signal, but no data being sent back and forth.

Any ideas? I'm on MJA, MJA radio, KT's latest kernel, with wifi fix flashed, and it happens most often on my work wifi network.
[Sprint Samsung Galaxy S 4 Android Development] vegasmach1:
Network Signal App. Sensorly as well. Battery usage with the KT ROM is outstanding.
[Sprint Samsung Galaxy S 4 Android Development] slixzen:
Can someone explain the technical differences (besides the inclusion of Knox) in the new MJA bootloader compared to the MF9 bootlader? I understand Knox is a pretty big change, but I would like to see what else changed, to see if it is worth the upgrade or not.

Is there any way to not use KT Kernel? No offense to him, but I would like as much of a stock kernel as I can get.
[Sprint Samsung Galaxy S 4 Android Development] guitardoc64:
The main difference between the two bootloaders is that once you go to mja, you can't go back. The kt kernel is working for the MF9 bootloader but stock is not. If you go mja all the way the stock kernel should work.
[Sprint Samsung Galaxy S 4 Android Development] Mardibob:
Interesting. I updated about two days ago, and I powered down my phone to change batteries and now my phone boots and then freezes. Tried reseting then clearing the cache and then full factory reset and still bricked. I'm gonna re-flash the ROM and hope it was just an one time bug, hopefully, that problem is just an isolated issue.
[Sprint Samsung Galaxy S 4 Android Development] dcxgod:
What if...

So I accidentally chose to take the OTA update, which failed on my current MF9 rooted device. I was wondering, however, if I could odin this back to stock mf9 rooted and redo the process as indicated in the OP? Would this fix the problem?

If not, is there a way to just get rid of the update notification?
[Sprint Samsung Galaxy S 4 Android Development] FanOfSkynyrd:
Just long press on the notification and uncheck the "show notification" button.

[Sprint Samsung Galaxy S 4 Android Development] Shardog:
So here is my situation: I have a Sprint Samsung S4, rooted, stock recovery, stock 4.2.2 MF9 and I tried the OTA 4.3 update. I also tried the QBKing method copy the file to the sd card and update from stock recovery. All failed.

Does that mean that I lost the MF9 bootloader?

Is there anyway I can check to see which I have?

In the about device screen under Secure boot status it says Type: Samsung.

Is there anyway I can get this ([HOW TO]Update S4 to Stock 4.3 MJA w/Root ,MJA Modem & Keep 4.2.2 MF9 Bootloader!) to flash without problems?

Thanks!
[Sprint Samsung Galaxy S 4 Android Development] dcxgod:
Thanks for this.

But...so can't flash back to MF9 root and do the OP's suggested way of getting to MJA if I had accidentally tried to take the update?
[Sprint Samsung Galaxy S 4 Android Development] wilderckw:

Back to MF9 Firmware?

Hey [MENTION=2646044]Mudavo[/MENTION], thank you for this. Very easy to follow and worked perfectly the first time. After flashing the MJA modem, however, my cell signal sucks. Can I simply Odin back to the MF9 firmware using [MENTION=1354510]Unknownforce[/MENTION] link? My concern is that in this exercise, I flashed the MJA modem only. According to unknownforce, the MF9 link is more than just the modem:

"this is FIRMWARE ONLY, not any data or system files, this will not put your device up to the latest ROM or add any features like samsung/sprint list out in their update releases. This is ONLY the firmware bits. (Modem, NON-HLOS, bootloader, sbl2, sbl3, tz, etc.)".

Will this work without affecting my Knox-free bootloader?

Thank you in advance for any guidance...
[Sprint Samsung Galaxy S 4 Android Development] Mudavo:
Yes. You can flash back to MF9. That is the beauty of staying on the MF9 boot loader :)
[Sprint Samsung Galaxy S 4 Android Development] blarg:
is there an MK 2 version of this method yet?

Something that would result with MF9 bootloader, MK2 software, and MK2 radio? (probably need to replace kernel too for wifi to work).
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Not yet, I need to have someone that has OTA'd to MK2 and get me a copy of their modem and non-hlos partitions, so that I can build the proper files from them. (PM for info on how to do this if you need)

I can no longer make them from the patch files like I used to be able to because of Samsung's new damned patch file format.
[Sprint Samsung Galaxy S 4 Android Development] blarg:
I'll see what I can do when I get home. My wife's phone is stock OTA'd so if she got the update I can pull the files. I got the update notice this morning, but didn't see her phone. Oh wait...it'll trip knox, won't it?

:(
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
I don't think it will if you don't replace the recovery, kernel or anything like that, a "temp root" IN THEORY should work without tripping any of the flags, because it happens at the system/android level, and you haven't modified any of the major partitions that I think trip this flag. (kernel, bootloader, recovery, modem, etc.)

I cannot guarantee that as I don't have a way to test it.

But remember... This is KNOX warranty, NOT your phone warranty, the only thing this specific flag voids is a the ability to use the device in a KNOX enabled environment. HOWEVER, this ALSO doesn't necessarily mean the Phone warranty is still in-tact even if the KNOX flag is 0. It just means that there are separate indicators for phone warranty and for knox warranty and that this specific indicator is NOT used as an indication as a void PHONE warranty.
[Sprint Samsung Galaxy S 4 Android Development] blarg:
we both work for an organization that's about to go BYOD...don't you need Knox flag intact for that?
[Sprint Samsung Galaxy S 4 Android Development] warhascome:
Galaxy S4 MJA

Ok, There is a ton of pages, but from reading the first post, if I already had the phone updated to MJA the first day I received it, I am pretty much unable to root the phone?

Or has someone figured a work around?

Thanks for an answer.

[Sprint Samsung Galaxy S 4 Android Development] guitardoc64:
You should be able to do that with cf auto.
[Sprint Samsung Galaxy S 4 Android Development] Unknownforce:
Yes and no, whether or not they USE Knox is what matters for the most part. Also depends on how well they know the device. If your IT Folk are smart enough to be aware of the flag, they could technically disallow you based on that flag. But it does seem unlikely, given the timing, while it's a great security feature on the device, as much as a pain in the ass for us it is equally as a pain in the ass for the people that have to ensure that it works. There are also many other methods to ensure that the device is suitable for corporate use. KNOX is just one way out of many. Easiest thing to do would be to just ask them, it's not worth losing you job over anyways, so better to just be up front about it and ask them what their qualifications are for this BYOD that's going into effect.
[Sprint Samsung Galaxy S 4 Android Development] E The Magnificent:

U can root but u will trip Knox. No fix for that yet.
[Sprint Samsung Galaxy S 4 Android Development] warhascome:
Thanks for the info. I found a root program that was from China, it worked and did not trip the counter. Then I read about fixing it so the Chinese version would go off the phone, with English replacement due to the Chinese one acted like a trojan. When I checked after Chinese, counter was still good and was rooted. So then I put the SuperSU app and it overwrote the Chinese one. Have not checked to see if that tripped the counter yet, but as of last checked, was not tripped. Will check when I get a chance.

Thanks

Galaxy S4 Root without tripping counter

Ok,

I am in no way responsible for tripping your counter. But, I did run this program via a youtube video.

If you also Brick your phone, it is on you, not me or anyone else.

Ok, go to this site and download the ROOT program. The button that says Download after your translate the page.

Install, download the root checker from play store. Should say root.

Then I went and checked to make sure the counter was not tripped. Either via a terminal with the download reboot comand, or the normal boot up button check. Search in forums to find out the exact way.

Now, after it is done, it will be in Chinese. From what I seen in another Tube video, that root is a trojan, so you go and use the the SuperSU program from Google play, and it overwrites it.

So, If a Dev wants to check out the coding of the Chinese one, then they might be able to write their own English Clean version.

Worked for me, so here are the links. Can't post links yet so I put spaces in them .

www .mgyun .com /vroot#

play. google .com/ store/ apps/ details?id=eu.chainfire.supersu&hl=en
