[Q] Experimental Kernel on Mahdi Rom - G Pad 8.3 Q&A, Help & Troubleshooting

Does anyone know what the Experimental kernel does?There are no informations about it in the OP of the Rom...I downloaded it but it appears to be for the Nexus 5...What is the difference between this kernel and the rom-kernel???

Who made the kernel?

After updating to the latest Mahdi rom and backing up what I had, I flashed the experimental kernel and wiped cache/dalvik.
It wouldn't boot, so I had to restore what I had.
No idea what it was supposed to do.

Yeah, if it said it was for the nexus, it wasn't going to work. Kernels should be device specific, and I am very skeptical of those that have been supposedly ported over, rather than compiled from the device's kernel source and then updated with new options.
Experimental in regards to kernel devevelopment means there are probably issues beyond the norm.

The filename is Mahdi-Hammerhead-exp-4.4.2-v1.7-23-03-2014.zip, but I thought that just meant it was somehow derived from the Nexus 5. Don't know why it would be posted in the Mahdi rom OP if it didn't have a chance of working.

To make myself clear.I said that nexus 5 thing, because the file of the kernel says hammerhead..But everything is fine..I use the rom as it is....I want to thank the dev for this amazing rom..A big thank you to all the devs..All of them have put a lot of work to their projects..I just made a question about this kernel.nothing else..Thanks for the reply..

(ROM) GingerBaked (CM7 source based AOSP-like ROM)

I take no credit for this other than building it and uploading it. This is 100% based off of code from Team Douche. Special thanks to cyanogen, Zinx, and Kmobs for giving us such great code to work with. Special thanks to Gridlock32404 for all the help he's provided me with android in general.
This is basically the same as the CM7 Alpha roms, but with all of CMParts and CM Settings removed.
http://www.multiupload.com/DU6VR2OMH7 (GingerBaked)
http://dl.dropbox.com/u/16719351/gapps-newmarket.zip (gapps)
http://dl.dropbox.com/u/11228290/recovery.img (ClockworkMod 3 Recovery)
If you haven't already been running a CM7 Alpha, you'll need to manually flash a new recovery image since 2.3 based roms are not compatible with the current recovery found in ROM manager.
Download the recovery image posted above, and flash using fastboot.
$adb reboot bootloader
$fastboot flash recovery /path/to/recovery.img (replace path/to/ with the actual path to where you downloaded the recovery image)
If you'd rather flash the recovery from the emulator follow http://forum.xda-developers.com/show...&postcount=361
once you have the new recovery, install the ROM through recovery as you normally would. You'll need a full wipe. After flashing the ROM, you'll need to flash the gapps posted above. Thanks to Grankin01 for putting those together.
Also, if you decide to go back to a froyo rom, you'll need to flash the old recovery. If you need help flashing the recovery,
check this thread: http://forum.xda-developers.com/showthread.php?t=852905
Also, if you are having trouble with adb/usb drivers check out the below thread by b16a2smith
http://forum.xda-developers.com/showthread.php?t=896206
Known Issues for this ROM are the same as all of the current CM7 alpha builds.

Wow thanks for this. And this is the real deal, proper credits and all. Unlike some previous ones. Will be flashing this one soon.
After initial boot, this ROM boots quickly. I did attempt to open the wifi calling, just opened and closed. Gonna load the rest of my apps and test the camera

The lack of credit is why I put this together in the first place.
So if the issues are the same and what not and its just cm parts removed, what are the benefits of this vs cm7 ...?

well obviously its for people who want a more original themed GB rom instead of having all the CM stuff.
what can we expect from this ROM that would differ from the other CM7 thread? i dont understand the necessity of fragmentation on a particular ROM unless each iteration has its own unique features that sets it apart from the next...

It is very simple. This is a close to AOSP ROM with CM base and Framework, just all the CM stuff removed. So you get a more pure Gingerbread feeling ROM like the Nexus S shipped with. Obviously it is not compiled on the original source yet but you get the same kind of experience.
Everybody has different taste. This is more of a very light ROM

from what I've read it appears it would be like Running eVil D's MT4G-G2 ROM as opposed to CM 6.1.2 RC2.

nexus roms question

i was looking for a new rom and i know a lot of people ask about the best rom for our nexus, but i'd like to know if there is some rom optimized just for the galaxy nexus......i mean that i know that cm and aokp are very good roms, but they are not specific for the nexus. I'd like to get a rom with all those features, but optimized for nexus hardware
optimized for galaxy nexus?
stock rom and kernel of course..
btw u post this on the wrong section..
As you post the question wrong here, you can browser here lots of roms are for Galaxy Nexus here now!!!!
Want to know the taste of these rom? Browser here, take a look of some users comments and Choose ONE to TRY!!!
Mine is Xylon! Enjoy~
Thread moved to q&a
It's not a taste matter. I would know if there is a rom tailored for Nexus

if you are looking for a rom that is soley build for the nexus and no other devices, i guess try to find the lesser well known ones. i dunno though i never run those ones. jbsourcery, aokp, cm10, etc i BELIEVE are all built for the galaxy nexus as well as some other devices. this has nothing to with how it will run on our phones. what matters is how good the developer is, and how effective you are at flashing new roms. dont dirty flash. wipe it like you wipe your ass and returning to stock via adb between flashes or every few flashes will help keep perfomance up. flashing to stock via adb isnt like flashing another rom, it will format and repartition your device. there is a difference between formatting and erasing.
any rom you will find for our phone is optimized for this phone, it has device specific drivers included, and is tweak and optimized to the devices specs.
What do you mean by optimized for Nexus hardware? CM and AOKP ROMs for each phone uses the unique drivers and stuff of each individual phone; otherwise the ROMs wouldn't work.
Optimized for Nexus hardware is pretty much just AOSP.
ok thank you for the replies.
For whom didn't understand my question, i meant that roms like cm are builded for different devices and the devs are not concentrated just for our nexus. In fact less known roms got more optimizations for our hardware. Maybe i'm wrong....this is the reason i asked here

perhaps you need to do a little more reading as to what a nexus device actually is....
if you see a rom in our dev section, it was built for our phone...its that simple. The best optimizations will come from the kernel of your choice, not the rom.

I am fairly new at rooting, flashing etc. This is the first time I've heard it's a good idea to flash back to stock every once in awhile. When you say flash back to stock, should a person be unrooting and locking the bootlader as well? Or just flash the stock rom and carry one?

[Q] Recently switched over to Xylon Rom

Hi guys, I'm new on this board and I just wanted a ask a few question about this rom. Currently I'm using the Xylon 2.3.3 and I'm loving it so far, running beautifully smooth. I just got a question about the gapps, I've installed the 2013-2-15 gapps with all the photosphere stuff, however there is a newer version gapp which is 20130301, should I update to that?
Also is the kernel that it came with any good? or should I change it to AK purity like a lot of user have said to make it run a lot better.
It's safe to update, just flash over the current gapps.
As far as the kernel goes, most users report great things from the AK kernel so it's worth a shot.
For future reference, please use the corresponding Pre-existing ROM thread to ask such questions. There is no need to initialize a completely new thread.

thanks I will in the future. btw I was just checking the kernel version. It seems like the rom has already built in with the ak kernel purity.030. Correct me if I'm wrong.

Is rooting+flashing custom rom a solution to my "prob" ?

Hey all
lately I noticed that my stock android 4.2.2 (not rooted) has become a bit sluggish sometimes. I like stock android but I feel as if the GNex is really running on the edge now in 2013 if I compare to the newest hi-tek android devices/Iphone 5 etc.
Could flashing a custom rom improve the speed and smoothness ? Also maybe I'd like to try out hybrid mode like you have in PA. I also heard a lot of good stuff about Sorcery, don't really know what would suit me the best.
Do you guys think rooting + flashing a custom rom would still my hunger for a new phone for some time still ?
Hope to have some tips that can move me into the right direction. Nonetheless I still love my GNex but I hate when it lags a bit sometimes..

Yes, it could. A new home launcher also could improve speed and smoothness.
Yeah, I think for sure you will be content with your phone longer if you try different ROMs on it occasionally, or even just recieving new updates to a current ROM.
sure dude why not.. if u root u can overclock and thus increasing your performance, rom selection is self choice related try every rom and kernel and stick to the one you love

What are the most performance/smoothness based roms ? Or is it more a kernel thing ? Although I don't want to experiment with 1001 settings and kernels on a rom before I get it right. I reckon that a developer puts a stable kernel together with the rom he makes and releases..

Everyone has their own favorites. I personally recommend you try the newest stable CM, or even the M series if you prefer the newest features before the are implemented in to the stable builds.
Stick to the prepackaged kernel so you don't develop issues from using a third party kernel on a ROM it wasn't designed for.
That's my preference, hope you find yours. "Best ROMs" or "smoothest ROMs" threads get closed quick around here.

Ok thx, should try out CM then maybe, seems the most logical step too. I consciously didn't use the words "best rom" , as that's indeed each one to its own. Though, smoothness is imo an objective thing.
One of the best things about flashing a custom Rom and Kernel is the Fast Charge support! Pretty much if you just use a standard USB port on your PC it will charge as fast as a wall charger.

First question... Have you rebooted in awhile?
Second question... How many background tasks are constantly running.
Custom ROM/Kernel makes sense only if you go for a minimalistic ROM/fine-tuned kernel. Honestly, Stock ROM is fine, unless you need features missing. Or look for just straight optimized ROMs like RasBeanJelly Vanilla and others that are only trying to fix bugs and not add bloat.
Kernel, pick your flavor, but always go with 'stable' ones and not nightlies if you want to avoid issues.
For me, I do Stock ROM (or would consider RasBeanJelly Vanilla) at best, and Franco Kernel (though stock is good enough).
Another point... Key Lime Pie (v. 5.0) will be announced likely in a few weeks at Google I/O 2013. Why deal with unlocking the bootloader, flashing ROMS, and Kernels, then to have to wait for source code to be released to get the newest and latest?
Bootloader was unlocked from the day I got it (to go from yakjuxw to takju). Now I just rooted my phone with custom bootloader, but it's still on stock takju. Do I still get the Google OTA's ? Iirc I need the stock bootloader for this ?
Have you tried to wipe data?
You can try this first if you like stock. If you want to try a smooth custom rom I recommend you xylon + ak kernel.

I believe TWRP and CWM will allow you to install OTAs, but you need to have stock kernel and no other system apps that are not apart of Google's stock Android. However, you wouldn't wait anyways for OTAs since you can just flash the updates that appear on XDA once they arrive. Either via fastboot or the custom recovery (if they work).
If you go to a custom ROM, you will not receive OTAs, (or shouldn't if the ROM was built right). You will have to wait for the ROM to be upgraded by the maintainer of it.
dude try something new other than stock..
CM 10.1 + ak diamond
governor = ondemand
stable,good speed..

Not sure if by mistake but, (as of the date of this post) there's no custom bootloader for any of the GSM/LTE variants of the Google Galaxy Nexus.
What he's talking about is a custom recovery. (This needed correction so as to not to mislead readers.)

Good point you're right, sorry should have been more clear.
I'm indeed talking about a custom recovery, not bootloader. Atm I only have lockscreen policy with clock hack and SuperSU/SuperUser apps who use the root. Is this enough to prevent me from having google OTA's ? Still didn't get to flashing another rom lol, I guess I like stock. And it might be between my ears but having rebooted + rooted the phone made it feel snappier again.
Thanks for all the feedback guys.

Again, if you alter system files the OTA will fail, if it needs to update those.
Well my (noob) question was if above mentioned things such as ClockHack who need SuperSU permission altered my system files?
I am using Purity with Leankernel. Gives me a smooth experience and great battery life.
Also it has the PIE and you can use XPosed framework to get Per App DPI with any ROM like I do.
But I have tried almost all the ROMS in the development section except for a couple maybe. I keep returning to Purity, Vanir and Cataclysm most of the time when I have something important come up and I cannt flash a new ROM every other day.

Kernel backup

Hello there,
I'm running CM 10.1 currently and looking into flashing a new kernel (KT747) for better battery performance. I am still new to kernels but I was wondering how I would go about backing up the current kernel so that I can restore it if anything goes wrong, or if I am unhappy with the new one.
Thanks for the help.
Regards,
Mike
I just flashed stable cm 10.1.3 and am in the same position as you. Let me know if you find a kernel for us! I'm going to continue searching tonight.

This is the kernel I'm looking to flash, looks like a great one with lots of options for performance tweaks and battery saving:

Also, I found an app called Trickster MOD from the Play Store that allows you to backup your kernel... however I'm not sure if that's the correct way to go about doing this, I just want to be sure to have a backup of the CM kernel in case things go awry with this one.

So I went ahead and flashed with that kernel and everything seems to work so far. I haven't made any adjustments yet for battery optimization, but I'm working on it right now. I used this kernel from that thread: http://goo.gl/52odw

Hey man, if that kernel fails you there's another kernel called leankernel, which I actually prefer over kt747. I can usually overclock higher with better stability. Though, it's all up to how your phone handles it. Try making a complete backup of your rom if you can to save your kernel. Good luck.

Thanks for the suggestion, I'm still waiting to find out if there's actually a way to backup just the kernel without having to backup the entire ROM. If I should happen to want to go back to the CM kernel I don't want to have to restore the whole ROM, I can't seem to find an answer anywhere.

I'm kinda screwed right now. The file system on 4.2 is awful, and if you restore a previous rom and install 4.2 again it creates more of a mess. I'm in the process of fixing all of these directories currently. Just be careful.

Try to just reflash the rom, or flash a new nightly over it. That's usually what I do when I have a kernel I don't like, it flashes right over it back to the stock cm kernel.

The kernel is great, it's just the file system from 4.2 creating duplicates of my directories.
