If you are on stock 4.4.2 with newest Bootloader with Knox then you can't downgrade to stock 4.2.2 via Odin. In fact you can't downgrade to anything below 4.4.2 at all. That's why most people did not take ota/upgrade to official 4.4.2, they kept 4.2.2 bootloader which was without Knox and flashed 4.4.2 custom ROMs.

Stock mms apk 4.4.4

I am on the latest insane kitkat 4.4.4 v4 and wanted to revert back to the stock mms apk in order to maintain the wifi mms functionality. (Which I always loved dark themed mms but it helps to receive texts and mms) So I was looking through the custom rom, and online, but could not find the stock mms apk for 4.4.4 to install onto my phone. Any help on finding the location? From looking online I thought it would be called secmms.apk or something similar to that. Also, I was looking into the previous version as well to copy it over but likewise could not find it. I am guessing I am looking for the wrong title for the apk. Any help in the right direction would be great. Thanks

Rooting my M919 kitkat 4.4.2 on MacOs

Hello all! I was trying to look through the thread and other threads for some answers but I couldn't really find anything specific to my situation. I had to restore my M919 to stock due to soft brick issues, but I restored it to the 4.4.2 stock version. I did so using a window's PC, but since I don't have the windows pc access anymore, I've been trying to find rooting solutions on macs. I have tried using Jodin3 but I for some reason, it cannot find the PIT file to make the flash successful. I've tried looking around for it as well, but no success.

I came across motochopper and it seems like a viable solution. But I'm not sure if I should use it since I've only seen it used for rooting 4.2.2. Can I use motochopper to root my 4.4.2 galaxy s4? Or if there are any other solutions to do so on my mac OSX, I'm open to it as well! Thank you!

Iv'e read around that it could be a bad sim since ive had it for over a year and never used it could be a possibility and also my imei matches the number on the back of my phone so the imei number being off is not the problem. give me suggestions/fixes please?

Also if i go to AT&T and ask them for help will i get in trouble for having an unlocked phone? sorry for so many problems im just desperate right now.

Thank you for your time (:

Okay i just got the phone and its on 4.4.2 baseband ends with NB4

Should i upgrade to the latest stock official update and root/will i be able to root after if i decide to go this way?

I may want to root and install a rom in the future. But i want to keep it stockish any recomendations?

Or can i install a rom and just flash radios/modems later through odin?

For rooting do i flash the custom recovery in Odin ? than flash the rom?

Any recommendation?
[T-Mobile Samsung Galaxy S 4] OriginalGabriel:
You already have KNOX so there's no reason go not upgrade (you'll trip the counter regardless, when you flash a new ROM).

Once upgraded, root it, flash a recovery, then flash the ROM of your choice.
[T-Mobile Samsung Galaxy S 4] The Sickness:
Flashing a rom doesn't trip Knox. Rooting doesn't trip Knox.

Flashing a custom recovery or custom kernel trips Knox.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
True! Only flashing a custom recovery or custom kernel trips the Knox flag.

However, the only way to root the stock 4.4.4 kernel is to use CF Auto Root, which installs a temporary custom recovery to do the rooting. Thus, you trip the Knox flag by rooting.

I have seen that after upgrading to 4.4.4, you can use ODIN to flash just the stock 4.4.2 kernel, and then use TowelRoot, which doesn't trip Knox, and then reflash the stock 4.4.4 kernel. This should not trip the Knox flag. However, I haven't tried it, since my Knox has been tripped for a while.

Rob
[T-Mobile Samsung Galaxy S 4] det0xx:
So what i understand. regardless if i root and stay stock or flash a custom recovery it will trip knox.

From my own research it also says once i trip knox i cant recieve OTAS or official stock firmware anymore through kies?

Does anybody in this GS4 forums create updated official stock firmware in the future?

Im guessig every S4 user has triped their knox with flashing roms ?

What are your personal steps to doing this?

Also does rooting the phone or tripping knox lower the quality of the camera or anything else like sony does?
[T-Mobile Samsung Galaxy S 4] a103:
You can update the firmware via Odin. You need to have official stock firmware for your device which you can flash via Odin.

Rooting does not degrade camera quality like Sony on GS4.

Check this for official firmware for TMobile GS4.

Custom Roms

So I still haven't been able to get my phone Carrier Lock Cleared. This is the Samsung SGH-I337 from AT&T. Phone was given to me. I want to use it on T-Mobile. Phone is running stock 4.4.2 which has kept me from unlocking it. I tried two different Unlock Companies but neither one could unlock it.

Would flashing custom roms or kernal allow me to clear the carrier lock? also, could I load a T-Mobile rom to allow T-Mobile features to be loaded? I understand that Knox would be tripped, but will that stop the phone from working properly? I don't use secure email clients (I use gmail, godaddy, aol).
[T-Mobile Samsung Galaxy S 4] a103:
I think only AT&T can give you the unlock code. Flashing custom ROM or kernel won't help.
[T-Mobile Samsung Galaxy S 4] lalec:
If you continue to use a Touchwiz ROM the camera should be unchanged. For other types of ROMs the camera will be different although it should still work pretty well depending on exactly which Touchwiz camera features you want to use.

Open Odin v3.09

Reboot phone in Download Mode (press and hold Home + Power + Volume Down buttons)

Connect phone and wait until you get a blue sign in Odin

[T-Mobile Samsung Galaxy S 4] det0xx:
Now that im on NH7 i can root with either towel root or CF ? Either one will trip knox? than from there install a custom recovery like twrp and flash any rom?
[T-Mobile Samsung Galaxy S 4] OriginalGabriel:
Not sure if CF works on NH7, but I'm pretty sure TowelRoot does.

Roting doesn't trip KNOX, but flashing a recovery will.

After flashing a recovery, you can flash a ROM.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
TowelRoot doesn't work on NH7 (4.4.4). Part of what they changed was fixing the security hole that TowelRoot was exploiting. He now works for Google.

You have 2 choices with 4.4.4, you can flash just the 4.4.2 kernel with ODIN, and use TowelRoot, and then flash the 4.4.4 kernel back. This will not trip Knox.

Or, you can use CF Auto Root with 4.4.4. It's simple, works great, very easy, but will trip the Knox flag.

[T-Mobile Samsung Galaxy S 4] Frankenscript:
You should make a record of it (write it down)for emergencies but nothing you do should mess it up. Rooting/flashing ROMs and recoveries / modems should not do anything to it. End users generally can't fix it if something extreme happens to mess it up.

Need help with radio/modem

Hey guys, I am running the wicked v10 and have recently been having problems with my radio/modem signal. At first I thought it was the ROM, but after reading around I have seen that others have had the same issue and they are not using the same ROM. I was wondering if there is an update somewhere to re-flash the mode/radio I tried searching for it, but perhaps I am using the wrong terms. The issue is that my signal will simply drop off, and I am certain the coverage area is not the issue, as my work leases out a portion of our property for a T-mobile tower, and the tower is literally 100 yards from my office. Often it happens after concluding a phone call. I cannot get phone or data signal and just get a circle with a line through it. Thanks in advance.

in Battery Graph the Mobile Network Signal is always black

Hi

(sorry for bad english)

I'm living in Persia, and I have a T-Mobile Galaxy S4 M919

MY Original ROM was MK2

I rooted my phone with this method :

I unlock my phone with this method and everything went very well.

http://xdaforums.com/showthread.php?t=2780006

(The antenna signal is always between 5 and 4, but the sound was good, as the case may be due to differences Frequency Band between T-Mobile and my Operator)

https://en.wikipedia.org/wiki/List_of_mobile_network_operators_of_the_Americas#United_States

I updated My phone to NB4 ROM,and I noticed in Battery Graph the Mobile Network Signal is always black, except for the occasional bit of green. However, coverage is still good as before

I've read the black color means that the radio is turned off or disconnected. it's True? :confused:

Should I be worried about this ? , that case makes it use more battery? (always searching for a better signal)

Generally how reliable is the Mobile Network Signal? :confused:

I've tested the modem NH7 as well as NB4 and often Mobile Network Signal is black.

Now I've installed the modem MK2 in NB4-ROM, and the Mobile Network Signal mostly green. Photo is attached. (Antenna still vary between 4 and 5 ,and is acceptable)

The difference between modem and bootloader is causing the problem? :confused:

I have this problem only on Android 4.4 ,is this coming from Android 4.4 bugs , or difference band of my operator and T-Mobile ? :confused:

Friends: What is your suggestion?

Which is better? NB4 ROM with MK2 modem OR original NB4 and I do not notice the Mobile Network Signal? :confused:

Thanks in advance. ;)
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Black usually means the radio Is off, like in airplane mode.

No signal is red. Poor signal is yellow. Weak signal is beige. Good signal is green.

Are you sure the radio isn't cutting out completely during those blackout periods?

Another oddity is that I can clearly see you have a signal from the status bar. Yet the graph shows the radio is off.

Is the modem all you have changed? Is this otherwise a stock ROM? Did you try a totally different ROM? How about doing full stock restore using Odin to see if that changes anything?

Your data issues are more than likely due to having a mismatched bootloader and modem. I have seen this issue especially with the new 4.4.4 firmware NH7.

LTE is tied to the bootloader. And you cannot Odin the LTE by itself.

I advise you to upgrade to 4.4.4 thru Odin. But remember, once you do you cannot downgrade the firmware.
[T-Mobile Samsung Galaxy S 4] khazook:
LTE is still not available in my country .

I'm not sure about upgrading to NH7 because i cannot downgrade if i has problem or etc . (and for root most use CF-Auto-Root and unlock boot-loader )

I hear some issues of NH7 and not want update at this time.

i stay in NB4 , unless Android 5 come for our device. or have major issues with this rom

but now i search to resolve this issues (Mobile Network Signal's Color is completely black in NB4 modem) and i hope i find solution.

difference between Bootloader and modem , May create a problem? if yes , In what context?

permission help

I was trying to enable writing titanium backups to the SDCard by editing the file:

/system/etc/permissions/platform.xml

However I was not paying attention and now everytime I boot up I get spammed with error messages "Unfortunatley, the process com.google.process.gapps has stopped". All apps also produce a force close saying about the same thing. Continuously. I can recieve calls and open up a couple of apps but only by the small window between closing error messages. Here are the steps I took when editing the platform.xml

First I edited the file as suggested:

Original:

Add the media_rw group:

Then I copied the file back to the SDCard. After that I overwrote it in /system/etc/permissions. Not realizing the permissions were incorrect. I restarted the device and started getting errors. I assumed it was the file permissions so I started up ADB and entered the following lines:

mount | grep system

mount -o rw,remount /dev/block/platform/msm_sdcc.1/by-name/system /system

chmod 326 /system/etc

chmod 644 /system/etc/permissions/platform.xml

chmod 644 /system/etc

mount -o ro,remount /dev/block/platform/msm_sdcc.1/by-name/system /system

That changed the file permissions so I rebooted by my device and got stuck in a boot loop.

So I rebooted into Clockworkmod recovery and tried to restore a working backup of my stock ROM. Got past the boot loop but still spammed by errors, so I tried to restore just the /system partition from the recovery using Clockwork's advanced tab. Seems like the errors are even worse. I wanted to know if by my description someone could give me a push in the right direction. Does anyone know what permissions the /system/etc folder is supposed to have? I suspect the reason this is happening is because I changed the /system/etc permissions instead of just changing /system/etc/permissions. Please offer any knowledge you have. I've pretty much exhausted the first few pages of Google and I don't want to give up and factory reset just yet.

Thank you
