I re-flashed the stock KK rom, rooted it, and took another crack at it. Lockscreen settings force closes on me and causes my phone to reboot every time. I can't screenlock my device at all. Annoying. Battery life is obviously bad especially if you compare it to megalomanic Roms.

Stock was running horrible for me. I only had 21mb of system memory available from scratch. Everything lagged severely or froze. I deleted a bunch of bloatware apps using titanium backup and now I have no freezing and much less lag (and about 400mb of free system memory). I didn't think that system memory was supposed to matter since Android apparently handles system memory very good (I could be confusing this with something else) but it seemed to matter in my case.

However, it runs good enough for me (now) to keep it on and continue trying to further tweak it to my liking.
[Samsung Galaxy Mega] MC FLMJ1G:
How did you root? I flashed twrp and then installed SuperSU. It is a lil buggy after root. I have the same problems... certain setting options DO NOT WORK after root. Lockscreen and Security settings for sure but not sure if something else as I have not had this long enough. That is a huge problem. What if I want to put a password later on or take off? I also cannot change the setting to install APK's. Sigh...

Stock was not bad for me. It was pretty decent. Not MEGArom great but much better than 4.2 I am in a dilemma. I love TW; camera, voice and multiwindow. I really enjoy those. The handful of apps I need for multiwindow work non rooted. The problem is adding apk's, this is huge. I did figure out a way to add apps without installing regular way but not all of them work properly. Wanam doesn't work at all and Xposed is glitchy. Surprisingly some Xposed modules do work.

I could go back to CM and have root and better performance than stock, sub to MEGA roms, but the camera is terrible, no multiwindow and no voice commands.

sigh...
[Samsung Galaxy Mega] curgervending:
I rooted by ODIN flashing PHILZ Touch Recovery immediately after ODIN flashing the stock ROM. In PHILZ touch recovery, I went into advance options and clicked on the option to re-root the system. I then rebooted the phone, went into the google play store, installed supersu and that was it.

I am having force close and reboot issues trying to access security and lockscreen settings.

I uninstalled and re-installed slimkat (CM11). I go between stock kitkat, slimkat, and megafire.

Anyway, I installed the xposed module, xhalo floating windows. it's the CM version of multiwindows. It's works different from TW multiwindows. In xhalo, the windows float. So you can open multiple windows, resize them and position them anywhere on the screen. It's not as clean and simple (in my opinion) as TW multiwindows but it also has options that TW multiwindows doesn't have (the windows float, you can resize them, and you have the option to snap the windows to any side of the screen - bottom, top, left, or right). So, in portrait mode, you can snap the windows to the left and right instead of top and bottom (TW multiwindows forces them left and right). Likewise, in landscape, you can snap the windows to the top and bottom (TW multiwindows forces them left and right). It also has that little touch menu option in between each window (when they're snapped) similar to the stock kitkat version of multiwindows. You can choose to pull any of the open windows, you can close any of the windows, you can swap window positions between left and right or top and bottom (depending on how you snapped them), etc. Give it a try if you haven't already. you may like it.
[Samsung Galaxy Mega] MC FLMJ1G:
I started from scratch and even without rooting I was having the same issues as you.

I tried CM11 and the faux multiwindow is way too buggy. The camera quality is terrible and no voice commands. If I am forced to be like this I am jumping ship asap. I need a cell phone that doesn't crash... I may just bite the bullet and pick up the NEw Nexus coming out... sigh... I love TW but this is too much and unacceptable.

also, I tried OTA but it said system modified... It told me to go to Kies but I have never had success with that useless software.

I did some messing around...

ok, i formatted, made sure EVERYTHING was wiped.

Used Odin to flash 4.4.4 Metro PCS Tar...

NO CRASHING at all... phew... Now... I have to believe it is a KNOX issue... lil by lil I may play with it... I can install unknown apps now but want to see what the real issue is.

What I will do is change all options I need, like accept unkown apps, and then try and root... I am going to try Kingo Root instead of flashing TWRP and installing Super Su during the weekend to see what happens... Not sure if it is a TWRP, root or a combination of the two...

MODEM????

Hello morning

Just a question, does someone has the stock modems? i was using mi metro mega in Movistar (mexico) just fine but last night i lost my network and now it just says "unable to register on network", I have already tryed the lock away, it's sim unlocked, and I already did a factory reset. Now the only thing missing it's trying out to reflash an old modem. can someone help me?

Old firmware

I don't think there is a recovery flashable modem.

But here's the old 4.2.2 firmware, this INCLUDES the modem, you flash it through Odin.http://www.sammobile.com/firmwares/download/24240/M819NUVUAMK7_M819NTMBAMK7_TMB.zip/

Will it brick the phone? :confused:

Unusual Audio Problems after 4.4.4 Kit Kat Update

Ok, so I recently upgraded to 4.4.4 Kit Kat USB tethered using Kies and have been experiencing two really annoying audio bugs.

The first is when using the stock music player, the audio quits or in some rare cases the song will skip back to the beginning.

The second is that, when receiving a call, the phone goes completely silent. As in, I hear no ring, and when I pick up, I hear no sound. This happens at least every other day and can only be resolved by reboot.

I tested unmounting the SD card to see if that would help and there was no difference: I tested by moving some music tracks to the phone's device memory and still got errors playing tracks.

I have no idea what could be causing all the hiccups. I upgraded the legit way using Kies.

Any help or insight would be appreciated. Thanks in advance!

Hi,

My Mega SGH-M819N is Rooted and running KK 4.4.4

I am having a weird GPS problem. When I turn it On, it stays on for about a minute and then switches Off and starts using "Power Saving Mode" (Cell & WiFi). FYI, I have the phone's Power Saving feature Disabled.

I did a Factory Reset recently, but that didn't help. I do not know of any apps that I have installed that would want to turn my GPS Off.

Also, even if I turn it on and then do absolutely nothing on my phone, the GPS still Disables by itself after about a minute.

Help???
[Samsung Galaxy Mega] Zeuszoos:
Hi,

*** Note: This phone has been running reliably with this KK 4.4.4 Rooted (PhilZ Recovery) setup for over a year.

Okay, I've got some really weird crap going on!!!

Yesterday, my phone just started wigging out! Hard!!! Everything was giving me "Close" boxes. Stuff just stopped working. I couldn't run anything without it erroring out.

I tried restoring from a backup, but no help. I tried Wipe/Factory Reset, but the apps that it does have after that, were still exhibiting the same behavior. Plus, another problem was that anything I would put on my Ext SD Card would save, but then when I rebooted, would disappear. This also started yesterday.

Anyway, a very long story (12 hours of working on it) a little shorter, even though doing a Factory Reset and then the MegaKat ROM V45 didn't work, I did finally get that to take, I wiped, then installed the MegaKat Zip, then rerooted and it has finally worked! I will have to set everything up again, but at least it's running.

But one problem remains and that's the problem of anything I write to the Ext SD Card will write and stay there, until I reboot. Then it disappears. My Ext SD Card was patched a long time ago and if it couldn't be written to, then it wouldn't allow the write in the first place. But I ran th patch again just in case and it said "No Action Necessary", so it's good.

I did run an Avast Anti-Virus scan too, just FYI.

Does anyone have any idea at all what the heck is going on??? Any help would be appreciated!

Thanks!
[Samsung Galaxy Mega] curgervending:
Thanks but l already tried that. The problem is I think the font I installed overwrote the system font file (my phone was rooted) and a wipe won't revert that back to its original state. If the install just added the font to the already existing fonts, then a wipe should have fixed everything but it didn't.

I actually have the i-9200 also (International version Mega) and installed the font without a problem. However, installing it on the Metro PCS version put me in a bootloop that I can't get out of (as mentioned it freezes at the Metro PCS screen).

Once the firmware is released, I should be able to flash it via ODIN and be all set. Problem is we don't know when it will be released (days, weeks, months?).

I got the SGH-M819N because of the LTE data (the i-9200 doesn't have LTE). Was gonna sell my i-9200 since I don't need 2 Megas but I guess I gotta hold onto it for now. I was hoping to get back the money I spent for the Metro PCS Mega (the i-9200 is selling used on ebay for about what I paid for the SGH-M819N new). Oh well, guess I gotta wait until I get this sorted out.

Do not lose hope. As long as you manage to access download (odin) mode, you still can recover.

Make sure you have Kies installed. Turn on the phone to access Download Mode (sorry, since I don't have Mega so I don't know what key combo to access Download Mode.

Once you accessed Download Mode, open Kies and connect the phone, and Initialize the firmware and wait, but you can "steal" the ROM which can be used with Odin.

Make sure you unhide the files and go to C:\Users\(username)\Local\temp

Sort the files by date modified and start the flashing. You may notice there is a huge file. Copy the file to anywhere and rename the huge file extension to tar.md5.
[Samsung Galaxy Mega] mingkee:

Use the fonts in unzipped folder if fonts in /system/fonts are overwritten.

The files are from Note 8.0, but it will work with Mega.
[Samsung Galaxy Mega] curgervending:
Ok. thanks. So far, I'm in recovery mode. Kies, however is not connecting to phone. Gonna reinstall drivers and see if that helps. I know the computer recognizes the phone because when I open Odin and connect the phone, the port registers.
[Samsung Galaxy Mega] b22ri22an:
having the same problem, i soft bricked changing dpi, recovery failed and cant get kies to connect
[Samsung Galaxy Mega] mingkee:
You have to look at device manager with the device connected in downlad mode and see whether it has error. If you see any, try to manually install the driver by installing Samsung ADB device.

Edit: Make sure this driver is installed in order to make download through Kies work (of course you have to fully install Kies 2.x first).
[Samsung Galaxy Mega] b22ri22an:
when you say download mode, do you mean recovery mode
[Samsung Galaxy Mega] mingkee:
Download (aka Odin) mode is different from recovery mode. You see "downloading... please do not turn off target" in download mode.
[Samsung Galaxy Mega] b22ri22an:
not familiar with odin, only devices i used before this were nexus and had a toolkit that did stuff for me so i'm kinda ignorant, how do i get into download mode
[Samsung Galaxy Mega] mingkee:
1. Turn off the phone

2. Press down and hold Volume Down and Home buttons, and press Power button until you see a warning screen. Press up to enter download mode.
[Samsung Galaxy Mega] b22ri22an:
ok i'm in download mode, but kies is still not connecting even tho i am showing the proper driver... am i screwed
[Samsung Galaxy Mega] mingkee:
Don't worry about it as long as you see the driver installed.

Simply download and initialize the firmware.

Tools -> update and initialize firmware (do not click emergency firmware recovery).

You can flash "dead" phone using this option.

[Samsung Galaxy Mega] curgervending:
After spending two days trying to get this phone back up I couldn't take it anymore. I took it back to the metro pcs store. They lost patience with it after about 10 minutes then went in the back brought back a brand new Mega for me. I don't think I'm going to do anything to the phone until a firmware or a custom recovery exists. That way I can either use ODIN to reflash the firmware or I can create a nandroid backup in cwm/twrp to ensure I can recover from a soft brick.

Whos running working Roms on there metro mega

And can you confirm which ROM and recovery..

For those that want to flash roms at least we have an idea what works so far.

There isn't any real mentioning of working Roms for M819n.

M819N Unlocking SIM Card help

I wanted a bigger phone and found this reasonably priced MetroPCS Mega M819N in my last travel but didn't activate it because I live outside the USA. When I get home I found out the phone is SIM locked. I called Metro PCS and they want me to have the phone activated for 3 months in order to release the unlock code but they don't offer any service in my country. I called Samsung customer service and they can't help either.

So I tried a SIM unlock with UnlockClient and the software apparently said that the unlock was successful but at phone restart the device regenerates some Android files by itself and the phone is SIM locked again and I am out of 25.00 bucks!

Is there any way I can unlock it for sure? Any hacks or working methods out there? I don't want to risk another 20 or 30 dollars to get the same results. Any help is much appreciated.

Yes, getting 36M in KC

Yes MetroPCS SGH-M819N unlocked, works great on t-mobile. Average down is 15M, but often 20M, and sustained bursts of 35M are seen. KC is a refarmed area so ymmv... Running silesh.nair's cm11, mokee, aosp, and beanstalk (all have populated apn's from the get-go). All run great, tho battery life is barely half of stock rom (sigh)

Btw, I also have the issue that others report with his latest twrp. When restoring a backup, the media folder isnt there so some UI sounds not triggered, and boot animation is the old school "android" most of us will remember from the g1 running cm. Clean installs are as expected, its only from restored nandroid backups.
[Samsung Galaxy Mega] MC FLMJ1G:
Thanks.

I guess just debloating is the best thing to do? Any other roms that help bat life? Half life lost is a big deal for me even though it is good from what I have read.
[Samsung Galaxy Mega] pcstable:
Unlock?

Btw, forgot to suggest unlock...

Here's where I went for my unlock (I527 and M819N) don't need to "buy" the listing, just use the html boxes in the listing itself, got both codes within 24 hours:

http://www.ebay.com/itm/Unlock-Code...394?pt=LH_DefaultDomain_0&hash=item23339b422a

If the unlock code itself doesnt work straight away, you must enter the subprovider code then defreeze code. They will provide you with these if the unlock code alone doesn't work.

As far as debloat, I tried that with stock (I527) it never reduced background apps or processes to any realistic degree, and you can debloat too much and prevent subsequent boots (yep, I did just that, thankfully had orig image to Odin it back). Titanium Backup will do whatever you ask, but heed the warnings! Even at&t's stock image is plenty fast, I just HAVE to have cm, etc,
[Samsung Galaxy Mega] curgervending:
Are you getting LTE data or HSPA+ data (going into settings, about device and looking at the mobile network type will tell you)? I have the SGH-M819N and can only get HSPA+ data with any of the non-TW ROMs. I only get LTE data with the stock TW ROM.

I attempted all the steps in all the threads across the Mega forum to no avail. I can't figure out for the life of me why I can't get LTE data on non-TW ROMs. I tried MetroPCS APN, T-Mobile APN, already populated APN's, manually creating the APN's, switching to all the different available networks, clean ROM flashes, dirty ROM flashes, clean dalvik, fix permissions, etc. (you name it). No LTE data. I hear others are getting LTE data so I'm still holding out hope that it's something I'm just not doing right.

That's for the I527, different freq's...

That's for the I527, which has many of the same bands, LTE and HSPA, but not all, and some are different freq's (850Mhz for one...).

As I've said before, I'm in a refarmed area, KC, so AT&T and T-mobile's LTE use the same band. Any AT&T LTE phone runs LTE on T-mobile. In a non-refarmed area, as far as I understand, you will likely get HSPA+. If you're running the old t-mobile APN of epc.t-mobile.com, try fast.t-mobile.com (specific for LTE). The article referenced above (not my link) works in a NON-refarmed area, no need for any fiddling in a refarmed area, just use fast.t-mobile.com APN.

I'm repeating myself...
