[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] cezical:
Can somebody help me with my phone please? I have this phone (L720T) on stock firmware rooted as it has been for over a year... but today out of nowhere it shuts off and wont turn back on. It doesnt go into recovery, download mode or anything it just shows the loading screen for about 2-3 seconds and shuts off and wont do anything until i take the battery out and put it back in and it still does the same thing. I thought it might be my battery so i tried turning it on with my charger but it does the same thing. Im scared its a hard brick but then again i dont even know how a hard brick is possible as i didnt install anything onto my phone to cause it... it randomly shut off by itself while it was working fine. Another odd thing is that i was able to get it to start up a couple of times after it stopped working but it only worked for about 10-20 minutes. Any suggestions on what to do would be appreciated.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
If it is a bad battery plugging it into the charger won't help... And it sounds like a bad battery to me. Spend the $10 or less and get a brand new battery on Amazon. Could also be the power button is stuck, when the power button is pressed for 7-10 seconds it cuts the power to the device. If it is stuck it could simulate what you are experiencing (this is the problem I had with my old S4, you can clean it but you need to have a delicate touch). It can be temporarily fixed by smacking the power button very hard against a surface to unstick it... Good luck.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Also...can you get into recovery mode? If no, then bilgerryan's reply is the best answer.... And if yes, does it shutoff in recovery mode, or is it stable in recovery?

If it's stable in recovery, then I'd say something is wrong with the firmware or Mal ware is involved, and you need to reflash your firmware.

I'm on OK3 5.0.1

I really hope sprint releases an updated firmware. Check out these two screen shots from the latest Belarc Security advisor app. A great security addition to your Antivirus app by the way (IMHO). I'm not showing the details of all 96, because it would take two many screen shots. In short, a lot of security bugs have found with the latest OK3 firmware.

96 vulnerabilities, 58 of which are High.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
Don't count on it... I highly doubt they'll release anything more for this device now that the 3rd generation after it has come out. Speaking of which, the geniuses here on XDA finally rooted the Galaxy S7. It may be upgrade time around Christmas, I get a 10% discount and $100 off a new phone with T-Mobile through my new job, but I still want to buy the phone outright so there is no contract.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Don't blame you. I would only buy it outright too in order to keep my grandfathered plan.

If I have to sign a contract Sprint will up my basic monthly charge forever.

The S7 is my choice of next phone as well. Been keeping my eye out for deals. It will be awhile before I can afford two of them. 2nd one for my wife who also currently has a 720T.

I'll be on 720T for quite awhile.

Can you send me the thread link where they rooted S7?

Hi Checkout these pics. I think I'm getting a false positive with the latest webroot antivirus definitions. According to my google searches, "android.smssend" is a virus but "wssyncmlnps" (com.wssnps) is the samsung updater service.

Just installed mcafee antivirus and it shows no threats detected.

Tried four other well known antivirus apps(avast, kapersky, norton, mcafee). All report no threats found. Cunclusion is false positive.

On 5.0.1 we have not seen any successfully reported unlocks and msl code acquiring attempts.

If you phone is paid for in full, you can call you carrier and they will likely give you your msl code and help you unlock it.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dea1222:
Most appreciated!

Sweet! I really and truly appreciate your offer. However, I've at least two pit files for the SPH-L720 (not T) that just simply do not seem to do anything (attached). I'll admit that I'm not the sharpest knife in the drawer and constantly learn stuff here and in other sites; I might be doing something wrong with ODIN. I don't know. My SPH-L720T (the Sprint tri-band) was somehow modified by the Minnesota cell phone guy to accept and run GSM SIMs; however, there was no LTE. I was getting only G2 and G3. I keep forgetting to check if that is simply because Sprint's LTE bands are not shared or used by any any of the predominant GSM providers here in the U.S. (T-Mobile, AT&T). I've got an alternative ROM running on the L720T right now - a CyanogenMod - that seems to only do CDMA. Thanks again and best regards, David

It doesn't appear that I'm allowed to post my two pit files. Sorry. Either I simply am not allowed or I screwed up.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] mattzeller:
Yeah, your not going to get LTE on a Sprint S4 on a GSM carrier, it doesn't have the required bands, but the pit file just tells the phone partition info. The link I put has the pit file for the L720t
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] helikvar:
Ok so it was more of an exploit and not a trojan as reported by Avast though if I understand it correctly the exploit could have been used to put a trojan or just about anything else on to a device. Oh by the way downloaded and installed your rom just lately and the new splash screen is pretty awsome..Ok the reason I was trying to download an older rom , was because I was trying to get my sph -l720t sim unlocked.I was on OK3 and the thread said unless I was on 4.4.2 that I should first of all flash the m919 rom .I wasnt to fond of that idea and reading that sprint bootloaders are unlocked I thought it mite be better to downgrade to 4.4.2 . though I am not sure you can downgrade after doing the lollipop update.

I feel like a dummy...I just realized after all this time that I could tap on "Cached data" in Setting>More>Storage and clear ALL cache in all apps at once with one easy tap and without a third party app. I gained back over 4 gigs of available space in seconds.

I've been doing some studying and it appears that android does not support a cutoff cache limit even if you have root ?

So you just have to flush it once and awhile, and with this built in clear everything in one tap method that I just described (and everyone except me has probably known about for a long time..lol ), it's easy to do ?

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dea1222:
Not a flashing guru or very knowlegable at all

My internet searches show that your phone is an AT&T GS4 - a GSM phone. A SPH-L720T is a Sprint GS4 CDMA phone (that can handle some GSM if one knows how). I think a SPH-L720 is also a Sprint CDMA phone. Who were you using as a wireless provider? Presumably AT&T or T-Mobile, or possibly one of their mobile virtual network operators (MVNO); for example, H20, Cricket, or possibly even Simple or Metro PCS. In any case, were I in your shoes, I'd fire up a copy of KIES. One of the main menu options is about restoring. Find the one that asks for model number and serial number (or IMEI? - I'm pretty sure KIES asks for serial number) (use the information from the sticker behind the battery). I recommend waiting for a confirmation from someone more experienced and knowledgeable than I. But that's what I'd do to start. Good luck.
