SPRINT Galaxy S4 Baseband = L720TVPUAMK5 Model = SPH-L720T

-------------------

Daniel,

Thank you very much. Not sure where you found that but I take your experienced word for it. I searched off and on for days, read for hours, and didn't see it...so I really appreciate your confirmation and instantly gave you a like.

About three weeks ago, I owned a brand new ATT I337 model, used saferoot on it, and it tripped the custom flag. I had to use ted77usa ATT unbrick method to get the custom flag turned off so that I could return the phone.

Now that you have confirmed that CF will root the MK5, I'll do some more re-reading to try and confirm that CF method will not trip any flags (such as custom and knox warranty).

Any more guidance would always be appreciated.

I'm interested in your outcome as well. I purchased this model when sprint put it on their site. I've been following a couple threads here but never saw a definitive answer on it working.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
You're welcome. And I found it in the same thread as I found that a member successfully rooted their MK5 triband with this method.

SPRINT Galaxy S4 Baseband = L720TVPUAMK5 Model = SPH-L720T

-----------------------------------

Thanks WLC108. I'm not sure when I'm going to try it yet. May be a week or so. I want to do more reading and hopefully get some more feedback on the MK5.

A few weeks ago, I bought a brand new ATT model S4. I tried a few methods of rooting it that failed, and I think CF was one of them. In the end, I used the saferoot method posted by ted77usa for the att model and it worked perfectly. It tripped only the custom flag.

Resetting the custom flag was difficult but I was able to do it with ted's expert help. This allowed me to return the ATT phone, because I wanted to switch to Sprint. Of course that does not mean that CF won't work on my new MK5 Sprint model. Daniel is a senior member and confirms that the CF method will work on the MK5...so that should be reliable.

I really like the saferoot method best. Ted indicates it will work on the Sprint model but since he is more of an ATT guy, I'm not sure I should try it. For now, I need to do more reading on the CF method again to refresh my memory.

I've said all this only to say, I'm not completely new at this, I have a good idea what to look for and ask about before trying to root and prevent getting stuck.

ted77usa was simply awesome at assisting me (a real noob at the time). I hope to find someone else on the sprint side that will help me like ted did.

Currently, I'm trying to confirm whether CF will trip any flags, and if so, can the flags be undone later if needed.

Note that CF will flag Knox.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
bummer.....then I don't want to use CF this early in my contract because it trips the knox flag.

Is there a method for resetting the knox flag later?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
At the moment there isn't. You may be able to use the Kingo app. I know it works on the regular sprint gs4 without tripping Knox. It should work on the triband version.

daniel4653,

k1mu's saferoot method is confirmed to work on Sprint MK5 and only trips the custom flag. It does not trip the Knox flag. I haven't tried it on my MK5 yet, but will soon (trying to decide if I want to wait for kit kat. I did try it on My ATT GS4 4.3 android with knox a few weeks ago, and it worked perfectly.

Check it out at http://xdaforums.com/showthread.php?t=2565758 post 1

At the bottom of post 1, you will see the reported success on Sprint MK5

If this is helpful, please add a Thanks.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
Hmm I'm surprised the Op never added the regular SPH-L720. I confirmed it on the thread that it worked.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] wlc108:
k1mu's method worked nicely on my mk5. Now to wait for a hotspot mod for this ver :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks wlc108

Here is some more news.

According to k1mu The "Custom" flag is set by a scanner that looks at the content of your phone, searching for anything that's modified or unexpected.

To clear the custom flag, un-do any changes you've made to the phone (like "de-bloat"), remove busybox, unroot, then reboot. Wait an hour and reboot again. You should no longer have any changes from stock, so you'll no longer be custom. It's easier, if you're planing to return your phone, to just flash a full-wipe factory stock ROM. (Not a "Stock" ROM, but factory stock from Samsung unmodified.)

I have not confirmed this works on MK5....and when I rooted my ATT GS4 a few weeks ago with k1mu saferoot, I never added anything else to it that requires root (such as nobloat, appquarantine, busybox or anything else). I did a full unroot and never saw the custom flag change back to official. I did several reboot attempts over the next few days and it never returned to official. It always said custom. It was not until I did ted77usa's unbrick method that it switched back to official. I then returned that ATT GS4 and switched to Sprint MK5. I'm pretty certain that ted77usa unbrick method for ATT GS4 would not work on the Sprint GS4.

I've also been told:

If custom doesn't go away do a full wipe either via odin, or k1mu's preferred method using the carrier-utility or kies.

or use Triangle Away. Gets rid of custom when you reboot

or use wanam exposed to fake the system status and it will allow you to be samsung official, 0x0 with root

I've not tested any of these yet, but hope to soon

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
If you're talking.about the custom/official that is shown on download mode you could Odin MK5 once you are unroofed and that will reset everything to official. It did for me on MK2 after using safe root .

I'm looking for a custom recovery and i don't mind tripping the Knox any help.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Custom Recovery

Greetings. I see you are a senior member, which means you understand more of this terminology then I do, so forgive me if I misunderstand your question.

If by custom recovery you mean change the "SYSTEM STATUS = Custom" flag back to "SYSTEM STATUS = Official" try one of these methods:

According to k1mu the saferoot developer, "the 'Custom' flag is set by a scanner that looks at the content of your phone, searching for anything that's modified or unexpected.

To clear the custom flag, un-do any changes you've made to the phone (like 'de-bloat'), remove busybox, unroot, then reboot. Wait an hour and reboot again. You should no longer have any changes from stock, so you'll no longer be custom. It's easier, if you're planing to return your phone, to just flash a full-wipe factory stock ROM. (Not a 'Stock' ROM, but factory stock from Samsung unmodified.)"

I've also been told:

If custom doesn't go away do a full wipe either via odin, or k1mu's preferred method using the carrier-utility or kies.

or use Triangle Away. Gets rid of custom when you reboot

or use wanam exposed to fake the system status and it will allow you to be samsung official, 0x0 with root

I've not tested any of these yet, but they seem safe enough.

When I had a AT&T GS4 and did the safe root, I was changed to "SYSTEM STATUS = Custom" and the boot screen when I turn on the phone would show a big "CUSTOM" instead of "SAMSUNG GALAXY S4". On my new Sprint MK5 GS4 after saferoot, my flag is still "SYSTEM STATUS = Custom" but my boot screen still shows "SAMSUNG GALAXY S4". since I don't see big annoying "CUSTOM" message on my sprint GS4 screen during boot, I'm not really worried about trying to reset the flag at this time.

In any case, I hope you find this helpful.

No a custom recovery as in CWM TWRP or PHILZ I tried twrp now I don't have a recovery at all I've done a lot of roots and phone flashes but this is my first Knox and it being a different variant from the SPH-L720 with different software also
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:
I prefer Philz, always did the trick for me. For whatever reason some devs say that you have to flash the rom with particular recovery, but lately I always do it with philz. I experimented also with TWR and I like it. Keep in mind that I'm not advanced user so I don't understand the full potential of each recovery.

Has anyone noticed any signal strength increases from S3 to S4? It would be nice to know if the S4 has a stronger general reception than the S3.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
Nope no difference for me. It has improved in some spots and the speeds are faster but I am sure it's because of the network vision upgrades that have been happening in Los Angeles for the past year.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I'm using MK5 4.3 and I've been doing a lot of speed testing using speedtest.net app. In my area, I noticed an average of 21mb down and 4.5mb up from the phone, but testing from speedtest.net app on secondary device connected via "wifi tether router app" to cell phone I was averaging 7mb down and 2mb up.

So I began adjusting different settings and repeatedly checking the speed from my secondary device along the way. From my secondary device, I'm now averaging 16mb down and 5mb up.

Can some of you try some speed tests from your attached device before and after and confirm these optimal settings?

Note: Please do a minimum of three speed tests before and after. In my experience? The first/initial test is the most unreliable.

OPTIMAL SETTINGS

WiFi Channel: 1

Interface: wlan0(Default)

With tether for me, I never got the exact amount. For example on 3G on my phone I had about 1.2 mbps download. Ran a speed test on my computer and it was about 2.7mbps.

Oh well (still a Sam-Noob here...). Good to know.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. I'm a network engineer and I understand these anomalies; but that doesn't mean there is not room for improvement and that everything is optimized as it should be. If the phone delivers 20-25mb stand alone, but only delivers 4-6mb in tether mode. The desparady is too much. Something is not right and the router is not optimized. Can you try the settings I posted and see if it makes a difference for you as it did me?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cruise350:
That's because there is serious deficiencies in the Wi-Fi tether apps in the play store. Once someone finally makes a mod for the hotspot on the 720T you guys should see near equal speed results while tethering. On my non-triband S4 my modded hotspot delivers great results.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Agreed. In the mean time, I hope the optimum settings help others and if I can get some confirmations I'll move the optimum settings to post one until some one posts a mod for native.

Sacs 4.3 only works for 720t not Sacs 4.4. I got stuck on Spark screen. Had to do Nandroid though to go back. With the nandroid, I received an MD5 mismatch, so i fixed that and I was able to do a Nandroid.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:
I'm confused! I know 4.3 works but 4.4 I'm having baseband issues that's why I asked for NAF modem.
