After the root phone loses coverage - Samsung Galaxy Mega

as the topic. My mega lose GSM coverage, from time to time is a full range and after a while to zero range. Is there a kernel that will correct this? and where to take the kernel to rom XXUAMED

If it only happens after root, then install supersu and the su binary and unroot.

I mean, I do not know exactly whether the root or the CWM. So I uninstalled the root and upload the rom again? And if there's a kernel into a separate upload?

[Q] Evil Fascinate 3.5.1 comes with perm root, correct?

I would assume this ROM (EF 3.5.1) includes permanent root, since there are directions for coming from stock ED01- would this be a correct assumption? I flashed this when i already had root, so I just wanted to make sure before doing the same on my wife's non-rooted phone. Thanks in advance.

You are correct in assuming it comes rooted. As in it comes with the SuperUser permissions and application already in the ROM/System.
You are incorrect in calling it "permanent". Rooting is never permanent. You could flash another non rooted ROM and lose your root rights. How do I know? I have done it and it confused the hell out of me!
cheers!

lol, true. I guess i wasn't clear by saying permanent root. I knew you could remove root, as i have done quite often for OTA update testing, and so forth. by permanent, i just meant that root would stick if you rebooted it. Thanks for the helpful information though

1 i flashed this kernel
2 installed SuperSU 1.3.4
3 flashed the official kernel from Samsung
4 still have root access!

I have the i9200 and confirm that this worked. I am now rooted. I have to admit it was scary taking the plunge. I just bought the device yesterday and was contemplating returning it. Did not want to brick my phone and have no recourse but it worked. I am now installing application on my device that require root and they are working.

I don't think so. As far as I know, the GT-I9205 kernel just has the additional LTE driver which is not used on the GT-I9200 device and should not cause any problems.

According to Phone Arena, the phone supports the following bands:
GSM:850, 900, 1800, 1900 MHz
UMTS:900, 2100 MHz
Note, the 1900 band is not under the UTMS, so I'm not sure if you will be able to get HSPA+ if you are in a t-mobile area that has been refarmed.

This is from Samsung's website under specs for the galaxy mega 6.3:
HSPA+ 21/5.76 850/900/1900/2100
EDGE/GPRS 850/900/1800/1900
I have the i9200 version of the phone and am using it on T-Mobile in NYC. I can confirm that I have gotten HSPA+ speeds as high as 12mbps download and 3.5mbps upload (although it's inconsistent - I think it has to do with the towers and the refarming of band 1900 - I also think we need someone to port an HSPA+ supported modem from a T-Mobile device over to this phone so we can have consistent speeds with signal stability).
Here is an example of the inconsistency: within a 15 mile drive my signal will fluctuate between HSPA+, Edge, G and, in certain spots, no cell or data signal at all. I'll get that full gamut of fluctuation all right within the 5 boroughs of NYC.

Can someone please post a stock kernel TAR for the 6.3 MAE firwware? I would like to try and flash back just the stock kernel and see if i can get screen mirroring to work again.
Samsung has this annoying habit to block screen mirroring from working when running a custom Kernel or a custom recovery.

Dev Edition: Rooting, Roming and Recovering

A few of us purchased the Dev Edition and it appears there are some things where clarification is required concerning the three "R's":
1. Rooting: I understand this wonderful rooting exercise is successful: http://forum.xda-developers.com/showthread.php?t=2290798. I would think since the Dev Edition is unlocked, an owner would only utilize Step 3, and NOT the kernel exchange section. Correct?
2. ROMing: Since the ROMS were created using the Loki enabled system, does this affect ROMing the Dev Edition since it is already unlocked? What does a user need to do? Or, does it not matter? Do the Loki enabled ROMS work on a Dev Edition?
3. Recovery: Again, it appears TWRP and CWM are Loki adjusted, so does this affect recovery on the Dev Edition and restoring? Also, is there a Stock Factory Image which will NOT turn the phone back to a locked bootloader? Or, does the one which exists OK to use?
I only ask these questions since a few of us are somewhat confused.
Thanking you in advance!

I've been thinking about buying the Verizon S4 Dev Edition phone, but have been hesitant due to not knowing how simple it would be to root. Is it as simple as just running MotoChopper? Or is there a better way?
Being that the bootloader on this phone is truly unlocked, can you install the current versions of CWM or TWRP that are LOKI enabled, and will it work on this phone? I haven't seen any compiled versions that were non-loki (standard).
Same question goes for kernels too.
The first batch of Dev phones sold out in less than 24 hours, so I'd expect some of the people that have them would start posting their experience with it here soon. At least, I hope so!
Root failed when just applying the Motochopper step! It says it installs correctly and then it reboots and SuperSu is installed and then I checked for an upgrade which it took. However, it says it cannot install binary, there is a problem and closes.
I uninstalled SuperSu and tried a few times to root again but it doesn't work.
My phone states:
Kernel Version: 3.4.0-562219 dated May 15th
Build Number: JDQ439.I545OYUAMDK
Baseband: I545OYUAMDK
Must be something we can do....

I wonder if step 2 and 4 are still required? (swapping kernels)
Even though the bootloader is unlocked, the kernel may still have root blocked?

It sounds like it. But wouldn't swapping kernels render the Dev Edition to a retail version? Kinda defeats the purpose, no? Or, am I missing something?
The question is: Does the Dev Edition have the same kernel as the Retail Edition? If so, then it would make sense to swap kernels. I think we need the devs to weigh in.

From what I've been able to gather, Samsung has put in place a SetUID restriction on the stock release kernel via CONFIG_SEC_RESTRICT_SETUID. Apparently the D2 prerelease kernel doesn't have this restriction in place. That seems to be why flashing that is required prior to using MotoChopper to gain root. What I can't figure out is why you can flash the release DK afterwards and still keep root?
On the T-Mobile and Sprint S4 they've been able to remove the SetUID restriction on their latest DL release kernel by recompiling the kernel source with the SetUID restriction commented out
Thanks for the thoughts and analysis. Hopefully someone will find an alternate
root method for the dev edition since it has been available for a week and it sold out in less than twenty four hours, somebody with know how must have purchased it and is tinkering as we speak.
I would hate to render it back to a retail version otherwise.

I think I may have found a solution. With the Developer Edition we have an unlocked bootloader, so there is no need to use loki. I was looking for a non-loki patched (normal) recovery that could be flashed in Odin. I think I found one here http://forum.xda-developers.com/showthread.php?t=2322675. Look for the "Latest version can be found here" link, not the "loki patched" link. The filename is : Philz_touch_5.06.6-jfltevzw.tar.md5
If this works like it did in previous unlocked Samsung devices, then we should be able to flash the custom recovery in Odin, and then boot into recovery afterwards to flash SuperUser. From there, we're rooted.
If I had my dev edition S4, I'd test it out myself. But I'm still waiting for them to get back in stock!
Great..am somewhat game to try. Well report back. Thanks!!

IT WORKED...somewhat!!! When it boots, I now get Samsung Custom and unlocked symbol and I am in Philz Touch Recovery backing up the image.
As expected, the backup image is 4GB+ (saved on external card of course).
However, I can't update binary for root.
You, sir, are a genius...thanks so much..almost there!
Not really rooted though. Can't update binary and when in Root Explorer I can explore most folders but Root checker says I am not rooted.
Now what do I do? LOL

Did you flash SuperSU from recovery via the zip file? (from this thread) http://forum.xda-developers.com/showthread.php?t=1538053. Look for the UPDATE-SuperSU-v1.41.zip file in the download section.
This should give you root after flashing in recovery! If you can't get root in a root app after flashing this file, then the kernel is blocking root. You can thank Samsung for adding that in the DK kernel.
You can easily work around this by flashing a custom kernel!
Let me know how it goes.

Good question. From what I have seen thus far, the recovery is the piece that has to be Loki adjusted to allow it to be flashed on a locked bootloader. I don't think the ROM cares one way or the other. The only thing I still have questions about is the kernel. Is the kernel in the Developer Edition different than the carrier version?

If we could get an MD5 of the Developer DK kernel (boot.img), and compare it to the MD5 of a completely stock DK kernel (boot.img). Or maybe compare the kernel build numbers? I dunno, just throwing some ideas out.

I understand how the method works. It's like they can't root the latest kernel or something so revert back for root and come back. My point is if your final goal isn't just a rooted stock phone, there is almost no point in this ? Because since the phone doesn't have a looked bootloader you can just odin a recovery and flash a rom without rooting first

Bad battery life since marshmallow update

Since the update on Saturday I can't get more than 2 hours SOT,before the update (lollipop) I used to get 3-3.5 sometimes 4. Same exact apps, settings (Wi-Fi on when home off when not,mobile data on when not on Wi-Fi auto switch enabled,GPS on all the time with little GPS usage mainly google location services being used ,everything "optimized". I'm really lost here. If anyone can tell me their experiences before and after the update that would be great with setting changes if available. NOTE: I'M NOT ROOTED (PURE STOCK).
Anyone?

You don't need s-off to flash custom rom or root.
Unlock bootloader, flash twrp recovery, flash custom rom, root (No need for s-off in all that)
And as @Deathmeter said, no improvement in battery life with custom rom or root
