OTG support in Android L - Nexus 4 Q&A, Help & Troubleshooting

I have flashed Android L b3p3 . I have tried to read the original thread for help but its so messed up there.I guess hellscore kernel is working with otg support. Can someone explain me the process how to flash the kernel ? There is some boot.img stuff i cannot understand.

I doubt KitKat kernels will work without some ramdisk changes. You may have to wait for our kernel devs to release a L Preview version.

I'm with Android L running in my nexus 4, but i have tested hellscore and helldoctor kernell and anyone support otg or maybe i have done something wrong. Do you know anything about the theme?
Thanks.

First flash lrx21t-permissive-boot , then flash hells doctor kernel's latest version for android l then flash universal kernal manager. Then install synapse. In misc of synapse enable otg. Thats it

I'm afraid that without an external power source you won't be able to connect that device to your Nexus 4 regardless of ROM/Kernel combination. The Nexus 4 doesn't put out a high enough voltage to power an external device without a power input!

[Q] change kernel nexus 7

hi i'm stape and i'm new for this forum and i have this question.
i put on my nexus7 the trinity kernel but the tablet overheats on the retro, and i want to change to standard kernel.
how can i return to standard kernel??
thanks for the answers
What ROM? Or are you on Stock? If on Stock the way i can think of is finding an AOSP rom and flashing the boot.img? Should have made a nandroid before flashing. You could also try using Franco Kernel.. its just like stock and his app is great.
i have a cyanogen 11 and i have changed original kernel with the trinity kernel but i want returned to original kernel
how i can do it??

You should still have the zip correct? Just boot into recovery wipe cache and dalvik. And reflash the ROM and gapps. Reboot and you'll be running the stock kernel.

OTG kernels?

Hi all.
My n4 is now bursting at the seams with ROMs. I desperately need to move them to my usb disk. I used to do this using ziddey/franko OTG kernel.I have now got used to using much faster, non otg kernels like trinity & matrix, unfortunately these at time of writing dont offer otg and i am no way capable of creating my own.
Anyine know of any other fast otg kernels?
I would just keep swapping between ziddey and other kernels but from what i understand franko one does something funky to the ram disk which would have a negative affect when other kernel is flashed back over the top.
Please help a noob : )
Thanks guys : )
Matr1x kernel now has OTG support. Head over to the Original Development you should see it. It's developed by Mathkid

Thanks, I'm a massive fan of matr1x and its what I'm holding out for re otg.
Otg not currently working in latest kernel. I know math kid is working on it as we've spoken about it.
Tbh is the kernel I want to continue using so wish math kid all the luck : )

[Q] Changing Kernel from Franco to Trinity

Hi
I am new to this and recently installed franco kernel on 4.3 Jelly Bean. I was wondering how do I change to Trinity kernel from TWRP menu I have installed on Nexus 4. I understand that I need Zip and then from TWRP I can install, but can anyone you has done it advice me?
I am looking for what I need to do in TWRP?
I am looking whether I need to go back to stock Google Kernel?

since you are coming from franco kernel, this is what you should do, via your recovery..
after you download what you need, reflash your rom(dont wipe a singe thing), the gapps(if needed), and then trinity kernel. then reboot. if you are coming from any other kernel, you dont need to reflash your rom, just flash the kernel in recovery then reboot
Thanks a lot
So in this case I should just install trinity kernel as I don't have any custom rom installed and no gapps. I hope I am right as all I did was just installed Franco kernel on stock phone and that's it!
Any cache erase etc etc before i flash new kernel?

no matter what anyone tells you, you NEVER have to wipe anything when flashing kernels, dont wipe dalvik, dont wipe cache.
well, its best to flash your rom again if coming from franco kernel, it changes your roms ramdisk. trinity grabs the available ramdisk. by reflashing your rom, trinity would grab your roms ramdisk instead of francos. but, most likely youll be fine just flashing trinity on top
Thanks again
When you say ROM, are you referring to stock ROM?
I guess I'm getting confused between which ROM you are asking me to reflash.

xthaparian, can I ask you to share your experience when you do it?
I'm exactly where you are, stock ROM (4.2.2) and Franco's. It's not that I'm not satisfied with it, just wanting to try alternatives. After being a "ROM whore" with my previous phones I unfortunately didn't have time to do anything with the N4 yet..
Thanks =)

OK here is the update, I never got around to install it because I think there is no 4.3 kernel available as yet. All is see is a kernel for 4.2.2
If I am wrong then someone point me to 4.3 kernel for Trinity

i do all of trinitys testing, morfic(dev) doesnt have a nexus 4. this is the kernel that we are testing in the thread right now, publicly. the release kernel goes on the website. the test kernels deemed fit for the public ill post in the thread, and/or my social websites. if you cant find the latest, or have any other questions(even not kernel related), feel free to ask, we are very friendly in the trinity thread
Ooh
Installed it from twrp without wiping cache etc and installed good.
But screen flickers like really bad and not at all buttery smooth...
Any ideas?

go to the roms main settings, developer options, force gpu rendering, disable the disable hw overlays if they are enabled. if you dont have a developer options in your main settings, press about phone, scroll down, press build number 7 times. when you get the you are a developer now message, go back to the main settings and go into developer options.
the reason this happens is because you are running stock, which is jwr(build version) and aosp is jss. they are slightly different(some different drivers). this difference cause this. most custom kernels are jss, aosp based. franco kernel is jwr, stock based. this difference does not happen often on a nexus. btw, jss is the newest version of android. the majority of custom roms are also jss.
OK this is what I have done
I have dine as you had told and checked the box that states "disable the he overlays"
This fixed my problem but I hope this doesn't have any other effect ..
How can I install the aosp built instead of jwr ?

na, thats how i normally run my phone. there are many aosp builds out there in both development sections, as i said most are aosp. im using rasbean, but there are other good aosp based roms as well
Thanks a lot all!..
this seems to work.
One last thing i like to inquire is that to install the raspberry, they recommend clean wipe and then install gapps and rom. Would this erase my current backup of franco based system image i created in TWRP?
And If I wipe clean, how can I install the raspberry rom ..its all wiped isnt it!!!
Thanks @xthaparian and @simms22, I had already decided to take this weekend to try some stuff on mine, but your tries made me more forward to do it. I must confess of all my past androids N4 is, for obvious reasons, the one which has more releases to try, and ofc a lot of tricks in the way..

rasbean jelly! :silly:
no, your nandroid backup stays, your data gets erased though. its like starting fresh. the storage wont get touched(dont wipe the system). as soon as you log in, go through the google setup, your play store apps should start reinstalling(if you enable it). most roms will jave this or something similar written in the op.
Ok Thanks again..
BTW which gapps should I use!...
i found a link on the internet

but simms22 your input shall be the final thing to close the thread..

i hear people say these gapps for 4.3 are good, they were recently updated(8/8/13) http://goo.im/devs/paranoidandroid/roms/gapps/pa_gapps-full-4.3-20130808-signed.zip
also, you will need the latest supersu/superuser. heres the flashable supersu http://download.chainfire.eu/345/SuperSU/UPDATE-SuperSU-v1.51.zip
I downloaded all as instructed ..
I am on raspberry
I'm on trinity kernel
Let's see the performance .
One thing I noticed is that this kernel jas all 4 cores running and max is capped at 1024hz.
Also the governor is set to ondemand.
Any thoughts on this. Any other tweaks I should do to make it much better. Franco kernel was using interactive governor.
Also the GPU is ocd to 485 and stock is 400 max.
Any comments to tweak the kernel better or Tue stock setting are good!
Thanks for help

OTG stock kernel

excuse me, is there a patch for the stock kernel to use with externally powered OTG?
I have not understood well the description in the various post.
Thank you and sorry for my bad english.
no answer??
Cant' say i've ever seen one for stock kernel. Maybe you could ask and see if ziddey would work on one.

I use this one, very stable and great on battery.
There's also hellsgod kernel, hellscore
http://forum.xda-developers.com/showthread.php?t=2586524
This one is also very very good.
Do note you need a proper Y cable, and then an app that can mount. I've found stickmount to not work as well or often as Paragon NTFS but give each one a try and see for your use. Both available through the playstore.

Kernel help issues

Hi I just want help with some kernel, at now am using resurrection remix 4.4.2 as to my point that am unable to create a swap file on SD card as my kernel doest not support it had tried many swap apps but non of them works.
As I searched on Google with 4.4.2 custom kernels and flashed many but nothing happens... Kernel name remains same as factory default
As far as I am really confused and need some help from you guys... (Still using swapper for root on my Asus tab with cm10 stable and it worked fine for me hmm... Was thinking can I flash cm10 kernel of my tab by backuping my kernel and try to flash it on my s4 i9500 will it work??)
Thx
No it will not work.
Anyway there's just two custom kernel out there that supports 4.4 custom ROMs, just two:
1- Maxfour v14.
2- Persues v19.1 modified.
Any other kernel you may have downloaded could be for the wrong device, that's why it doesn't get installed.
