Flash S4 Custom ROM ML2

Alright, so I've enjoyed modding my Android devices since I got my first Android running on 2.2, especially because of the options to tweak CPU usage, and just (from what I have noticed) better general usage with all of my devices. I purchased this phone because of it's similar power usage to the S4 and it being water & dust resistant. However, most of the development that I have seen for this forum has been for the i9525, which is the international version. I have the i537, and have been going crazy with battery drainage issues, and I think only a custom kernel/new ROM can fix this. Could somebody point me in the right direction of where to go? I've heard talk that after MF2, installing Safestrap right now is essentially not possible, due to bootloader issues.

SafeStrap works for every version of firmware for the i537, you just need to use the proper version. If you're on ML2 I think you need 3.71, but please check to make sure because I could be wrong. As for a custom kernel or tweaking the CPU, it's not going to be possible on the i537 because the bootloader is locked and you are forced to use the stock kernel. You can try a custom ROM through SafeStrap, but I don't think it's going to help much. You might be better off upgrading the NE3 or NH3 and trying a custom ROM through SafeStrap there.

So essentially until we get the bootloader unlocked and can install a custom recovery (Like CWM or TWRP, instead of using SafeStrap), no "real" custom ROMs? More just ROMs based off of the stock kernel/modem/etc.?

Correct, and most of the people who were leading the development and research of unlocking the bootloader have decided to move on to other things within the last week. At this point it looks like the bootloader will never be unlocked. There's always a slim chance but it's not looking good.

[Q] Double Tap on screen to wake up?

Guys I am actually stock at the moment but doubletap to wake up screen is the feature
which I really want on my M7, I read some where long time ago that it was not possible on
M7 since it was a hardware feature but recently I came across a kernel for M7 with this feature. see below
http://forum.xda-developers.com/sprint-htc-one/development/kernel-elite-kernels-t2961835
The above kernel needs a GPE L Rom.
I am thinking of rooting and installing a custom rom now, I wanted to ask what rom should I
download in order to get this feature since I am new so I have no idea what a GPE L rom is.
Thanks in advance and sorry if its a noob question!!

This is a gpe l rom

Thanks a lot, So if I am not mistaken the second Rom you mentioned has this feature built in but
if I need this feature on Nocturnal Rom I will need to flash the elite kernel?

As thick said, most custom kernels do come with double tap to wake, aka dt2w.
I'm assuming you know the procedure for rooting and flashing a ROM.
In order to get dt2w, first flash a ROM of choice. Boot up, and set it up according to your liking. Then, find a compatible kernel (we can help you with that), and flash that. Boot up again, make sure (in your phone's settings) that the kernel flashed successfully, then download a kernel tuning app like TricksterMOD and go into "Screen Wake Settings."
Note: some kernels may use AROMA, which lets you configure dt2w while flashing. The above should still apply if you want to change your settings later on.
Thick's ROM comes with it built in, but most other ROMs don't.
Happy flashing, and remember, ask twice, flash once.

I appreciate it!!
I rooted and played around with different Roms on my previous phones e.g. HTC Hero, NS4g, and Evo4G
but since my HTC one is still being updated via OTA officially I didn't proceed with rooting yet.
I really wanted DT2w feature and I don't think any update would give me that feature so that's why
I am thinking about rooting my phone. I really appreciate your help since you said you can help with
choosing a kernel please go ahead and suggest a good kernel and few feature rich/stable Roms.

I would suggest SD 12 since it's on the latest base (.12, which has some important bug fixes) and it's relatively close to stock.
Along with that, I would suggest using ElementalX 18, which is one of the more easy Kernels to set up. It uses AROMA, so you don't have to download any apps to adjust your settings later. I had a good experience with the battery saving/thermal throttling/undervolting settings (you'll see those come up when you try to flash it). I don't recommend messing with the clock settings, however.
Wipe (default wipe in TWRP), flash ROM, boot, set up, go into recovery, flash kernel, reboot, wait, reboot again. That's the procedure I follow.

I have finally rooted my phone and I am in process of trying different roms at the moment, I tried to flash the ElementX18 kernel on my stock rooted rom but the installation failed so Now I am going to install SD12 which you mentioned and then flash the ElementX18 kernel. Since you mentioned you had a good experience with thermal throttling/undervolting can you please give me safe or your values so I can give them a shot as well. Thank you

EX 18 is a 4.4.3 kernel, you probably used it on a 4.4.2 ROM. A 25 mV undervolt with "run cool" setting would be good.

Yes you are right I was trying it first on my stock rom which was 4.4.2 if I am not mistaken that was the last official OTA
update for me. I am on SD 12 ROM and EX18 Kernel at the moment and loving it. I tried SlimKat which was not bad but for some reason I couldn't fix the resolution of the screen everything was too small for me (icons,fonts etc). Latest Liquid Smooth didnt recognize my sim card so I had to move away from it. It seems like for now SD12 is going to be my daily driver.
In case if I want to give SlimKat another shot can I use EX18 on it or it's only a sense kernel? also SlimKat is 4.4.4 so what good kernel can you suggest which will give me DT2W option?

[Q] To Root or not to Root?

Hi All,
My Moto X (1st Gen) is about 4 months old. I'm contemplating on rooting the phone. Is it worth the effort or should I patiently wait for the Lollipop update to come in (whenever that is!). I used a lot of custom roms in my old Nexus 4, so missing the excitement of a new rom. just a bit indecisive at the moment. Would love your opinions on this.

I am using the Moto X for nealry 9 months now. Never thought of rooting it as I didnt find any bloat here like the Touchwiz

I am honestly very tempted by the ROMs out there. And I don't know why but I'm definitely noticing some performance lag. Tried everything but not seeing a lot of improvement.

Before you go contemplating this question, figure out if you'll be able to root your phone in the first place.
Then instead of asking this question, ask whether or not you should unlock the bootloader. It's the only way to maintain root since 4.4.4 patched the vulnerabilities used to attain root.

There are reasons why I would root like Tasker(full functionality),a custom kernel or UI changes

I rooted my X so I can play with gravity box and other stuff. Unrooting and relocking the bootloader isn't hard to do and that's what I'll do once Lollipop comes out for my phone. (Already factory reset my phone once from custom Rom).

I meant to say return to stock recovery. I read somewhere that you can't get OTA with a custom recovery, Rom and rooted.

Gotcha, that is true. Stock recovery and stock system and you are good to go.

I personally root all my devices for better control. However, I personally don't use Roms because I want a stock experience and that includes boot animation and themes. The only Roms I have ever kept on my phones were ARHD and Paranoid Android. If neither are available, I go with Xposed.

Questions about Verizon Nexus 6

I just bought my N6 yesterday from Verizon and I spent some time last night reading up on things but I would like some further confirmation from some experienced users. So I've read a few posts where some have bricked their devices by flashing cm12 while on 5.1. The Verizon N6 came with 5.1 already so is it advisable to not flash cm12? And while we're on that topic, is there anything else you should not do while on 5.1? I was looking through all the roms/kernels and some are not updated yet. So if I'm on 5.1, is it ok to flash a rom/kernel that is not 5.1? And the encryption stuff is confusing as well. I'm sure the device will be a little faster with encryption disabled but is it really that big of a difference? I apologize for being a total noob when it comes to Nexus devices. I've never owned one, I've always had HTC or Samsung. I haven't ran cm since I had my HTC Rezound lol so I'm anxious to run it again. So if someone could please tell me what roms I can and cannot flash and just give me some general advice about this phone I would greatly appreciate it.

it is NOT ok to flash a rom for any other version than what youre on. so dont flash any 5.0.2 roms or kernels if youre on 5.1. (exception being the radio. i believe that can be swapped without incident, but youll have to do some extensive reading in the General and Development sections)
personally im on 5.0.2 for now until chroma gets realllll shiny and polished
i havent been encrypted since my first bootup, but my understanding any lag associated with that has basically been resolved

Simply inaccurate. You can run 5.0.2 roms after updating to 5.1 without issue. Just don't touch the bootloader. You cannot downgrade the bootloader from 5.1.

Anything that is 5.1 yes, I would stick to ROMs based on the "E" build of 5.1, since that's what you're phone came on. Most ROMs are in process of updating to E.

my bad

How far can i go on my phone?

I have a non dev Moto X from Verizon (XT1060, first gen). It is currently running 4.4.4. What is the most I can do with it? Reading several threads, I am unable to find a conclusive answer regarding this. Looks like sunshine doesn't work nor do most one click tools. My goal is to flash a debloated ROM at the very least if possible.

You won't be able to flash any custom rom without an unlocked bootloader and that's that really. At most you could root(when possible) and manually uninstall bloatwares from the stock rom. I'm glad I had troubles upgrading my phone initially and was able to read about sunshine app on time.
Sent from my XT1060

to the moon and back at least, of course try krypton, or maybe even the modded 5.1 for the 1060, I prefer krypton but the modded 5.1 came a long way quickly I just wasn't feeling the change from simplicity (less options but works perfect for me) of Moto Assist, to the more complex options in LP :/ Check out the respect threads for each rom!

Safestrap only works for 4.4.2 no?
