It all depends. Distance from towers/repeaters, buildings inbetween and the materials they're constructed from, etc. Think of it like some jerk's car stereo. Inside the car it sounds normal, but outside, and 3 blocks away, all you hear is the bass.

Alright, I just got one of these, and am trying to root it. I am following this tutorial.

androidxda.com/root-samsung-galaxy-avant-sm-g386t

I plugged it in with the device on for a few, and it installed four drivers. When I go into download mode, plug the phone in and open Odin, I do not get anything from Odin. It does not seem to be detecting it at all. I have tried a few different cables with no results. As a side note, when I open the device in windows explorer, I get no files, and it's named "Fcc D (SM-G386T)" Driver reinstalls have not changed anything.

How to enabled band 12?
[General Questions and Answers] Masterchief87:
Hey, I used to be one of those jerks lol.

Im also half deaf now because of it too.

You might need to download and install the samsung usb drivers. The drivers for odin are probably different than the ones that are used just for copying files and stuff. The tutorial you mentioned actually gives you a link to download the drivers that you need. I copied this link from their tutorial. Just scroll down the list until you find the Avant. http://androidxda.com/download-samsung-usb-drivers

B12 for the impatient

I found this on Howard Forums:

Dial this code: *#197328640#

You will get the ServiceMode screen at the final #.

Touch the menu button at the top right. Select the Key Input option. Enter Q and touch OK, then go back and bring up Key Input again. Enter 0000 and touch OK.

Wait about 5-15 seconds, and the service mode menu will change. Choose (2) UE Setting and Info.

From this menu, choose (1) Setting.

Choose (2) System.

Choose (9) Next Page.

Choose (7) LTE Band On/Off.

Choose (5) LTE B12 On/Off.

Choose (1) B12 Enable.

Use the upper-right menu button, and use Back until you arrive at the first menu screen.

Power off the phone, then power it on.

You can check to see if the setting sticks by going back to the LTE B12 selection.

Note that if you live in a market where there's a TV transmitter on broadcast channel 51, you're not going to find any B12 towers any time soon. Chicago is such a market. :rolleyes: However, when I was near Grand Rapids and Mt. Pleasant, MI earlier this spring, there were B12 towers active.

EDIT: Note that TV channel 51 is the RF channel, which, in the digital TV era, doesn't necessarily correspond to the channel number you see on the TV set.

Thanks for the B12 setup info! It's running now and my signal strength just went up a bar or two and throughput is up. :D
[General Questions and Answers] jcl972:
So you went through it all with no problems?

---------- Post added at 02:01 PM ---------- Previous post was at 02:00 PM ----------

Do you need to disable the current band being used?
[General Questions and Answers] Bobby Tables:
No need to disable anything, this merely adds B12 support. If it gets a better signal on Band 12 rather than the usual Band 4 or Band 2, it will switch automatically. T-Mobile might aggregate B12 with other bands in the future, but I'm also not sure if the Avant supports (or will support in the future) carrier aggregation. If I bring up the status screen with *#0011# I see a "CA- DISABLED" line in the report. I'm not sure if that means "disabled in the firmware" or "disabled in the baseband" or "disabled at the tower."

It's possible to set band preferences via *#BAND#, but I leave mine on automatic (and there won't be Band 12 in the Chicago area due to the existing Channel 51 TV transmitter, and once that moves to a different channel, AT&T will have the 700A block here). For me, it's mostly for my visits to Michigan.
[General Questions and Answers] jcl972:
Thanks for your advice. I'm in the North Dallas area I've read some posts that say band 12 is here.

Is there some kind of app that will tell me what specific bands are usable in my area for Metro PCS?
[General Questions and Answers] Tekfresshie:
I

Just bought mine last month. I like it although coming from a g3 from Verizon there is much to be desired. I'm really new to the tech genius world lol you guys are all gods to me for doing the things you do. I want to learn how to do this and now just doing it understanding what I'm doing and how. I have rooted plenty of phones but I want to explore more. I have rooted my tmobile galaxy avant using a flash firmware I think this is the one actually.
[General Questions and Answers] Bobby Tables:
Not an app, but here is a web site that has maps of T-Mobile spectrum holdings. Also on the site is another map with 700A (Band 12) holdings and exclusion zones highlighted. (NOTE: sometimes the maps are flakey - a couple of times I've gotten a 500 error from Google.)

Once you bring up one of the maps (linked further down the page after the explanations), you can click on any county to see what spectrum is available. It is applicable for MetroPCS as well, since it has become a budget brand for TMo.

Note, however, these are not coverage maps; at the time of this writing, for instance, they don't yet cover northern Michigan. North of a line from roughly Muskegon to Howard City to Mt. Pleasant to Pinconning, it's still AT&T roaming (at least for T-Mobile customers - is roaming available for MetroPCS customers?).

Note that the 700A block is 6 MHz wide, so forcing your phone to Band 12 should only be done if you have no other alternative. It's usually best to just leave band selection on automatic and let the phone use Band 12 when it must.

The normal Band 4 and Band 2 LTE blocks usually have more bandwidth (10 to 15 MHz typical, sometimes 20 or 25). In areas with LTE on Band 4, T-Mobile is in the process of moving 3G/HSPA+ over to Band 2 to provide more LTE bandwidth on Band 4. This is supposed to happen in the Chicago area at the beginning of June, providing 15 MHz for LTE instead of 10.
[General Questions and Answers] Masterchief87:
Have you installed a custom recovery and made a backup yet? If not I strongly suggest that you install Teamwin or Clockworkmod recovery and make a full nandroid backup in case you mess something up after rooting your phone.

D-FUSE has made an app that makes installing either of these recoveries and switching between them easier than ever. First you will need to install busybox. I reccomend using JRummy Busybox Installer. Once you have installed busybox you can then use the Avant Exploded app to install CWM or TWRP recovery.

So let me ask to make sure I got it right. Band 12 covers a farther area? And goes through buildings better correct?
[General Questions and Answers] Top Nurse:
Automatic or locked into Band 12?

Thanks! It was my understanding that enabling Band 12 only works if you have a Band 12 tower and that otherwise it automatically locks on the best Band. Am I incorrect here?

I don't see any difference switching back and forth and I noticed that my area has a Channel 51 red circle on the map. However, even with Band 12 enabled I get both data and cellular coverage whether I enable it or not. :)
[General Questions and Answers] jcl972:
[/COLOR]

Do you know anymore about changing settings in the service mode? Any other nice tweaks? Thanks for Band 12 by the way!
[General Questions and Answers] Bobby Tables:
Even if Band 12 is enabled, the phone will use the band with the best reception. I would think it would give more priority to a wider band when it's available and has good reception. Enabling it just gives one more band for the phone to use when searching for towers.

Rooted "Official Status"

I just wanted to follow up here and find out if anyone was unable to get your rooted and custom recovery phone changed to "Official Status" in the About Device folder. I went back to a stock phone, rooted, and changed to TWRP to see if I could duplicate the process. Scared the heck out of me because I had made a lot of changes and wasn't sure if I had ended up with a custom one off. The process appears to be doable because I'm back on "Official Status" once again. If anyone has trouble I will go back to stock and report back exactly what I did to make it happen.

As a FYI, this does not change what pops up when going into TWRP or the ODIN upload screens. However, it seems to me that some smart programmer may be able to decipher what causes the "Official Status" change and perhaps apply it so that it changes the BIOS and defeat the KNOX warnings as well. :D
[General Questions and Answers] Masterchief87:
The process for getting back to official status is as follows. Download the newest Odin firmware for your device and the previous one also.

(1) Back up any important files that you have on your internal storage.

(2) Do a full factory reset including formatting data.

(3) Flash the older firmware and allow the device to boot up normally.

(4) Skip through the setup process and do another factory reset with the stock recovery.

(5) Flash the newest firmware and allow the phone to boot up normally again.

(6) Boot into download mode and check to make sure that both "system status" and "current binary" both say "official".

(7) Repeat steps 2-6 if needed.
[General Questions and Answers] lazer9:
Probably a dumb question. Regarding this "Band 12" enabling discussion.

Have a T-Mobile branded Avant. Just ported out of their service 3 days ago to "Cricket" which uses AT&Ts towers in my area. Would I benefit by enabling "Band 12" via the instructions a few pages back if anyone knows?

Actually this is my GF's phone, my primary is the Note 4. So I don't want to mess it up. Just to add, I am rather impressed overall so far with Cricket's service/reception!

:highfive:
[General Questions and Answers] Planterz:
Cricket is owned by AT&T and uses their equipment, so there'd be no benefit to enabling band 12 if you're not on T-Mobile, MetroPCS, or one of their MVNO's.
[General Questions and Answers] lazer9:
Thanks for the clarification. Sorry I will revisit & give your post a "thanks" tmrw. Lol, I'm out of Thanks for the day it seems. :p
[General Questions and Answers] Top Nurse:
Perhaps I need to clarify here. I have a rooted phone with TWRP recovery with an "Official Status." So unless the store goes into the download screen or recovery screen they will never know I got a custom status.
[General Questions and Answers] Masterchief87:
I didn't know that was even possible with this phone.
[General Questions and Answers] Planterz:
It can be faked with Wanam Xposed.
[General Questions and Answers] JazzMartian:
Yeah my phone's been all but seriously messed up lately. Lost my root and recovery, haven't been able to regain them. I have been unsuccessful in reinstalling an update through ODIN, over and over and over again. My counter keeps going up, and CF's Triangle Away isn't doing anything about it! I'm having a difficult time here! My phone still works, but it's only a phone now. Meh. Who wants that? Not me. Might as well roll with an Obama phone.

Anyways, I thought I read that a new Sammy update was just released a few days ago or so, for this phone, but I can't find a working link, or concrete evidence of it. If it's real, and somebody has it, I would REALLY appreciate a working link. I'm gettin' to my wits end with this! :mad:

Thanks.
[General Questions and Answers] Top Nurse:
Mine doesn't have anything spoofed. After making the necessary changes and rebooting, the status says it is scanning or checking for a few minutes. Then the status changes to official. :)
[General Questions and Answers] JazzMartian:
Ok well after finding a new ANK3 update, as I think it's possible that one of my problems was a corrupt/degraded ROM I was flashing. Idk for sure. So, I went into New OS install mode, and backed out, for some reason, and my phone booted up as if it were brand new, which was really what I was looking for anyways! I lost all my apps, which does suck, and I have a lot of re-downloading/installing/setup ahead, but this is gravy. Gonna see if there was a new update, which is what I initially thought had happened (didn't make sense to me though). I mean for like a day no matter what version of Odin or FW I threw at it, it would boot up unaffected!?!?

All in all, as :mysteriously" as ish broke, ish got fixed! #I.Want.Lollipop

*EDIT:

After checking things out further, I see a Sammy OTA Software Update in my queue. Looking forward to seeing what's that's all about! I need to take some extra precautions as far as making a backup before "tampering" with my phone again. Think I'm gonna take my time a bit on this one. Is Helium about the best option for a "proper enough" non-root backup app? I've heard before it is, and have the premium version. I wanna make sure to unlock Band 12 first this time as well, as it appears as though maybe Triangle Away did work after all?! Due to the state my phone's in right now, it seems so fresh and so clean. ;)

Edit #2:

It's just a Samsung Security Policy Update. Sorry. I'm questioning whether I should install it? Seems like it could possibly screw me over. I've only got less than 6 months in on this Android scene, so I could use some help from time to time, like us all. :)

Edit #3. Ok, I read into it. It's an ob

KNOX

ious update, with words in the URL titled "locking down your android phone". Um please no, Samuel L. Cellphone. Enough KNOX for me, thanks.

Edit#4: Not trying to spam the board here or anything good peoples, but my phone is oddly showing up under device status, as also being official at this point! I meant I've rooted it many, many times, unlocked the bootloader, installed TWRP. And I've never even heard of the Wanam Xposed module, let alone used it. I don't know if it's from Triangle Away, or what the deal is? But I'll take it! I don't plan on re-rooting and all that business, until a Jellybean update, which will hopefully be real soon.
[General Questions and Answers] Bobby Tables:
For what it's worth, I just checked my stock/unrooted (Band 12 manually enabled) phone for updates, and it's saying that it's up to date (with the ANK3 build). That being said, some time this month it's (supposedly) going to get the "official" Band 12 update, so I'm holding off on rooting mine.

I did install the security policy update some time back... hope it doesn't bite my behind. If I had to guess, it's something SELinux-related.
[General Questions and Answers] Masterchief87:
Hopefully this update will include more than band 12 support. Lollipop would be nice. I used to hate LP but I'm growing increasingly bored with KitKat.

The security policy updates shouldn't hurt anything since they can be easily uninstalled just like updates to any other system app.
[General Questions and Answers] jcl972:
Let me tell you what happened (if i can) For some reason I had to reinstall my firmware on my phone. I didn't wipe I just put Odin on it and low and behold all my apps were still on it. And all the settings were the same. Except apps that needed root were not working. So I put Odin back on it and with cf auto roots help I got rooted and at the reboot all the color came back to the status bar and it's icons (xposed framework mods after reroot) so i was like "cool!" Then I realized my boot sound was playing and that my system showed custom even though those tweaks were applied. So i tried to uncheck, reboot and recheck the tweaks then rebooted. Didn't work so I uninstalled Wanam, rebooted and went to Xposed downloads and downloaded Wanam again, enabled it,rebooted and then went to the settings reinstalled the tweaks and rebooted. Didn't work! The device still shows system as custom and my boot sound plays, all tho both are tweaked and before reinstalling the OS they did work. And the other tweaks from Wanam are working.

Any idea on how to get those tweaks back running? Did by laying the OS on top of installed tweaks revert some files from xposed or from wanam to get corrupted by stock files? Any one know how to check those certain files? I'm still pretty new to this so details would be important as that I may not always know what your talking about.

Every time i flash zip file my phone wants to "optimizing the apps" is this normal cause it wasn't on my last phone?
[General Questions and Answers] Masterchief87:
It is normal for your phone to say optimizing apps after you flash a zip unless you just did a factory reset right before flashing. When it says optimizing apps what it is doing is extracting the classes.dex files inside the apps you just flashed and copying them to the dalvik-cache.

Looks like the official Band 12 update (AOD7) for the Avant is now available. Anyone try it out yet? I've (superstitiously) turned off Band 12 on mine just to make sure that everything is bone-stock before (if) I try it.

How would the update work for metropcs if so how would update manually?
[General Questions and Answers] Bobby Tables:
I don't know what they're doing on the MetroPCS side of things. I'm on T-Mobile and I'm about to take the plunge as I write this. Hopefully I'll be able to go on to root and a custom recovery afterwards (I'll probably try that next week, since I won't really have time to d--k around with factory resetting and then reinstalling/reconfiguring apps). If not, no biggie.

Looks like it's not quite rolled out yet, at least for me. When I go to "Software Update" in the About Device section, it's saying mine (on ANK3) is up-to-date.
[General Questions and Answers] redsfan27:
I just finished installing the update. I had to do it through odin because no matter what I did I couldn't get the phone to find the ota or Kies to find it. I just downloaded the firmware from sammobile and used odin to flash through download mode. After everything got situated (no data was wiped or apps) I went on to re root. Root worked the same way as before except for some reason SuperSU didn't flash with the .tar file. Lastly, I just finished installing the xposed framework again. So far everything seems the same as it was before. Just wanted to let everyone know that root is still attainable after the update.

Edit: I'm on T-Mobile
[General Questions and Answers] Bobby Tables:
I got the OTA when I tried it this morning. It went smoothly, but the hidden service menu is either disabled or under a different code. That is, *#197328640# still brings up the service menu, but the Q and 0000 key inputs no longer do anything. You'll see the menu blink for a moment, and then it's back to the standard service menu. As for Band 12, I won't know until I'm in an area where it's available. Between WPWR-TV broadcasting on Channel 51, and AT&T holding the 700A block in the Chicago area, that won't be happening here any time soon. Band 12 is live in the Grand Rapids and Mt. Pleasant areas of Michigan, and there are reports of it going live in the Indianapolis area as well.

It's probably a good idea to play it safe and manually disable Band 12 before applying the OTA (which I did).
[General Questions and Answers] redsfan27:
I use *#2263# to force band 12 and *#197328640# still works for band 12 for for me.
[General Questions and Answers] Bobby Tables:
*#2263# does show Band 12 as a preference option, but in *#197328640#, key input Q followed by key input 0000 just brings me back to the usual debug screen that only has "information" menu entries.
[General Questions and Answers] redsfan27:
I guess I'm confused what you're trying to do with *#197... I assumed you were trying to see the band info. This is what it'll show if you click basic info

And this is what *#2263# shows for me

I wouldn't think you would need the key input and 0000 if you have both commands.
[General Questions and Answers] Bobby Tables:
See my earlier post about enabling Band 12 on the earlier firmware. On the older firmware, after entering *#197328640# and bringing up the service menu, you can use key inputs Q and 0000 to bring up a hidden menu (which is needed to enable band 12). That whole menu has been ripped out, or the codes are different (one or the other). There were a whole lot of other settings and information screens available as well, though I didn't change any of them.

That's why I suggested going back and disabling band 12 if you enabled it manually, just in case the OTA misinterprets things when it installs. It's probably just paranoia on my part.
[General Questions and Answers] redsfan27:

I'm having problems reinstalling Xposed do you know a little about Xposed?
[General Questions and Answers] lazer9:
What version of Xposed are you trying to install/update? Be careful, there is a "Lollipop ONLY" in dev/release already so absolutely do not try that one by mistake.

Also, are you going with (Assuming KitKat version*s) , the latest stable or beta?

Lastly, what exact problem are you having with it re-installing?

Depending... A few thoughts off the top of my head:

-Completely uninstall it, reboot to recovery (TWRP) & Wipe Cache and Dalvik.

-Reboot to system & re-install Xposed app THEN proceed to load it and select [Install]

Last thought: I am not sure how much or if dependence on "BusyBox" being correctly installed or updated so if all else fails, possibly look into that.

Hope you can get it resolved. Feel free to PM me if further issue and I will try to help so we don't clutter this thread... Unless others are having issues with it and can benefit from the discussion. :good:
