1. I have the 5.0 Juggernaut ROM, what's the difference between kernel and ROM? How do you choose your kernel?
2. What's the best battery saving ROM and kernel that has all features of the T898?

1. ROM is like the looks and all the little extra stuff of a car. Some devs may decide to put some aftermarket parts on it to make it look cooler, and function differently.
(overall looks and the stuff you use everyday)
KERNEL is like the ENGINE and ECU component of the car, it controls how the car functions.. the smoothness, the strength, the clockspeed. There are plenty of v6 engines in the world, but do they all work the same? nope. Some are tweaked to work best for certain CARS/ROMS.
(OMGAH ROM SO SMOOF SUBER BADDERY LIFE... KERNEL)
well thats the basic breakdown of it.
2. Each device works is different... some kernels/ROMs combo works differently on each phone...
But I have to say.. the devs we have here are all top-notched devs.. you can't go wrong following any of them. USUALLY the devs will leave all the features that are widely used by people and add other perks to the ROMs... sooo Just go flash crazy..
remember kernels and battery life needs a couple days to calibrate with one another.
BTW I find it useful to just stick with one or two devs you can devote your phone to, and just use their stuff.
Hi everyone. I have been googling around for a way to extend my G Pad's battery life. On the way, I stumbled upon the Franco Kernel who many people consider the magical kernel to extend the device's battery life (some claiming even if you don't undervolt the CPU).
However, it appears that it is not working on the G Pad, atleast when I tried the franco installer on the playstore. I am using slimkat (which I believe is an AOSP... I have read somewhere that it works on AOSP devices, but though they didn't say which device, im leaning toward nexus only devices but im not sure).
Anyone tried and successfully installed this custom kernel? and on which ROM? Thanks
I thought Franco Kernel was exclusive to Nexus devices only? Where are you seeing that he has one for the G-Pad?

Not really. Actually on his installer application on google play the list of compatible devices are only the ones in the nexus line. But I do see in some threads for speeding up the android, franco often pops out. And since franco is compatible with AOSP custom ROMs, just figured, perhaps there might be a way to install this custom kernel on non-nexus devices with AOSP-based Custom ROM (i.e. Slimkat, or Pac-man ROM). But at the moment, im too scared to try it out on my own device because I just recently had it serviced for screwing up my partition table
Though I don't think custom kernels touch the existing partition table.
You need someone on here to port francos kernel over for our device.
But you can still use his app to alter certain settings, if his app is similar to fauxs and Trinitys.

I have heard of Faux's (his installer app in the playstore indicates that it unofficially supports other devices or something along those lines) but I had a keen interest in Franco's kernel because many has attested to its usefulness and that it saves quite a bit of battery life which the tablet could use.
Since there was a GPE version of the tablet, I was hoping they might port it aswell.
I guess kernels aren't like servers in the sense that, say for example in Linux, as it is based on x86, regardless of the CPU as long as its using the same x86 architecture, the kernel should be compatible. Following the same logic with Android which is essentially Linux which uses predominantly the ARM architecture, I was hoping that theoretically, the kernel will be compatible as they are using the same architecture... Although I can be wrong.
I would test it myself, but im afraid of bricking my device as I just hard-bricked it and lost quite a bit of my 9 lives... Dunno how many I have remaining
Hehe, it's not worth trying, as it wouldn't work. I'm not sure what would happen tbh. I don't think it would brick, I think it would just bootloop, but honestly it's not worth trying.
Have you looked at greenify?
It's great at what it does, but it is only saving battery during sleep. Mine is great in sleep, but it's not a vast saving of resources. Once you boot the tablet up you can literally watch the battery percentage ticking down

hmm boot loop I can live with. I might just give it a try when I have the time and summoned enough courage. Yep I do have greenify and didn't do much in improving the battery life. But atleast I think it did something.

in contrast to Linux distribution, our kernels are device specific as there are different drivers for different devices by different makers. On top of that, the ramdisk itself which is associated with the kernel to make a complete boot image, can have different mount points depending on the device.
You would think that all of this would be standard but of course with different makers of different phones, tablets, excetera, this just isn't the case.
Neither Franco's kernel, nor Faux kernel will work with the G pad. While I have done some work to port over different items from different kernels, I own the Google Play edition and not the stock LG tablet. Maybe one of the other kernel developers for the stock LG tablet would be open to porting over some of their work.
if you would like, you may also look in my signature for a guide on how to roll your own kernel for the G pad, and a couple of the other kernel developers have used it with success for your device. It is a complete guide start to finish, copy and paste style for anyone running Debian. check it out!

Interesting stuff. Only little problem is I don't have a debian based machine currently (only using redhat based Linux ATM). Ill install Ubuntu on my "virtual lab" and see if I can try it when I have the time. Thanks a lot for your input.

No problem. I use AntiX, a Debian derivative and highly recommended it. You will find it far lighter, and with some really neat tools. Ubuntu is not all its cracked up to be...

its more like, its the debian distro I have lying around so I don't need to download anything else. fits the bill. Although I will take note of that AntiX

If you use Ubuntu, you will have to adjust some of the dependencies, as they use their own packages. Unbuntu is a Debian derivative but is not compatible with the apt database. Let me know how it goes if you decide to do it!

I see. guess theres no harm in creating a new vm for this. Lemme google around for the installer and try it out when I get the time. Though I am quite loaded for this week and probably the next too
So I just picked up a HTC One M8 (AT&T variant). I am no newbie when it comes to rooting/flashing custom roms, having had a Galaxy S3, Nexus 5, and still owning both versions of the Nexus 7, however I just want to make sure I'm fine to flash before I go ahead and end up doing something stupid.
I already unlocked my bootloader successfully, loaded TWRP 2.7.0.2, and rooted the phone, but I keep reading about S-OFF and Sunshine and Firewater and I'm like, WTF? Do I need to enabled S-OFF to flash a custom ROM/Kernel? If so, is there a free way to do this (I see Sunshine costs $25 bucks and I have no idea what it does or why I need it)?
I figured I'd ask before trying anything, but I don't want to get setup if I'm just going to flash over everything anyway.
Also, I'm quite a minimalist. I like Sense, but I'd like a ROM with some optimizations performance and battery saving wise but not so much a visual overhaul. The realistic usable additions are welcome, but I don't want a ROM that is completely themed and doesn't mesh well with the default Sense 6 style. Can anyone recommend a nice ROM to start out with?
First off, although S-OFF is NOT mandatory to flash custom roms and kernels, it may be required to flash firmwares that may be needed to match the custom roms firmware - IF the custom roms firmware does not match your own. Simple answer: No, you don't need it to flash custom roms/kernels.
You can try Firewater to S-OFF but it just doesn't work for everybody, if it doesn't work for you then Sunshine is your only option.
As for a rom to start out with, really it's all about personal preferences. For the description you said, Android Revolution comes with a stock look with the option to change visuals if you prefer. Already optimized so you don't have to touch any power settings, voltages etc.
Roms don't create good battery life. Setup and usage does. So use any rom that appeals to you... Not what you think or they claim, will improve battery life. Rom and kernels make a minor difference in battery life at best.
I, and many others, know this for a fact.... As we run any rom or kernel, setup the same way, use the device the same way and we can get similar battery life on all of them. ?

truer words were never spoken..plenty of tools out there to maximize battery life, but rarely, if ever, is it totally determined by your rom/kernel choice
So I never really used "mainstream" or "flagship" & this is my first Samsung phone ever... & That being said the battery on this thing is s*** & I took the liberty of reading on here about the S7E battery hack, not knowing anything about modding or hacking phones. I took it to get the battery swapped, but my phone wouldn't boot, only showed the charging screen. So instead he put a S6E+ in my phone. The old battery was in it since 2015 (got it pre-owned through boost) so it's already better even without the phone recognizing the new capacity. I Rooted my phone for the first time, using ODIN, TWRP, & SuperSU, but I didn't make a backup first. I tried installing 2 different Kernels, Kiboi & SkyHigh. Kiboi had some kind of error before booting & said seandroid not enforcing on the Samsung screen and wouldn't go past that part. Removed that and tried SkyHigh kernel, it worked but got stuck on "Image Support Required" "Creating Image" so I took the original firmware from Samsung, wiped my entire phone and started over.
*UPDATE: I've switched from SuperSU to Magisk successfully & Synapse is working & SkyHigh didn't work because I installed v4 instead of v6*
So my main questions are these...
1: What Kernels for 920P will recognize a S7E battery.
2: What are a few things I should NOT do to avoid severely damaging my phone's OS/Software?
3: AccuBattery is reporting innacurate readings because it can't recognize it's not the original battery. How do I get my phone to recognize the new capacity in my settings & AccuBattery?
I am completely new to all of this, thanks in advance.
I figured a lot out. I've successful flashed BigDaddy ROM for Nougat, & SkyHigh v6.0.0 Kernel. Rooted with magisk. How do I make my phone recognise a S7 Edge battery?
(SM-920P) [Rooted] Custom ROM & Kernel combos for Nougat 7.0?

The driver at that layer is not within then S6 base kernel. Send me the output of “ls -lR /sys”.
I intend to keep this kernel going well into the future, no plans to switch phones for as long as the battery keeps working but I can add support for other phones if there are testers.

This is fantastic news I just grabbed a new s6 from boost the other day for 100 bucks and was sad to see that there was little to nothing as far as development went for g920p but came across your kernel and I just love it..so many options in synapse it was overwhelming at first but now I want more I paired it with with the uni debloat mod floating around here that with some slight modification ended up working out quite well and was able to have 19gb of free space (and that's with an almost 8gb TWRP backup I have just in case I break something lol...so yes please keep up development of you would thanks alot

Same here, that's how I got mine. Right now I'm on BigDaddy ROM for Nougat & SkyHigh v6 Kernel. I'd be willing to test if @tdhite adds support for the S7E battery mod, but I can't find the "driver layer output" or whatever it is he needs, I'm new to all of this I think I'm learning it all very fast but I'm still confused on a lot of the abbreviations, codes, lingo, ect. My only issue is I think the ROM uses way to much memory? I'll only have like 500-300mb left out of 3 gigs within an hour or so?

I have noticed that as well but I don't believe it is the ROM. It is the SWAP file from the Sky Kernel. When you go to Synapse and go to the Memory tab, mine is set at 2047mb. With 2698 total memory, that leaves 651 mb of available memory.

Okay thanks, that makes sense. The struggle is real here... I kept getting some weird problem where Magisk would randomly keep uninstalling and I couldn't access my Samsung Cloud. I reflashed the ROM (with S6 Launcher instead of S8) then the kernel. Haven't had the problem since.
NOW my issue is with Accubattery. I'm reading less than 2 hours of SOT!?!!!? My battery has the S6E+ installed and it's supposed to be 3,000mah, but I'm having worst battery life than I did before. I'm so confused I've tried calibrating it several times using Synapse & [ROOT] Battery Calibration Apps.
Hi guys!
Thought the topic may serve someone when googled someday so I thought about "diverging" from standard Q&A noob thread.
Basically I recently switched from 3T but thought it'll be nice to have it as an additional "standby" device (think of it as spam-device). I'll replace battery (3 years of service is pretty long) and then I am thinking what ROMs / MODs or APPS would be best to prioritize battery life. I was initially thinking about obvious: installing fresh rom then there's Franco Kernel (which I can underclock in it's dedicated app), keeping screen low, disabling GPS and other services that drain battery etc.
But maybe there's something better? I remember for galaxy s6 there was this "extra simple" mode that made phone last days but could be disabled if needed, maybe there's something that you can recommend?
Have an awesome one!

Some A11 roms are bringing extreme battery saver. That should help a lot (the rom that im using now has it - octavios).
