DoPa made a patch to give OTG to the Sero 7 PRO (sero7pro-usbotg-dopa-v1.1.zip)
(See http://forum.xda-developers.com/showthread.php?t=2470998)
Could this be used to give OTG to the Kobo Arc 7HD or could it be modified to do so?
If this can be done, please give instructions about how to install patch to the Kobo Arc 7HD.
Thanks
stock rom
can someone please provide a download link for the original kobo arc 7 android 4.2.2 jellybean firmware zip cause I was such an idiot and I didn't back up data and I try to make a custom rom and the device is now bricked with boot loop adb doesn't work and fastboot doesn't work either please provide a download link
Kobo Arc (OLD), status?
Hi guys,
I've just read through the whole thread and frankly it just gave me a headache. I'm a software developer and I'd like to help, but I have zero experience with android or Cyanogenmod so I need some help. I have the OLD Kobo Arc and I'd love to be able to install something more recent than the latest official ancient Android 4.1.1 system update. So, let me fire a few questions:
1. Can anyone quickly summarize where we are with the OLD Kobo Arc? Do I understand correctly that you guys have so far managed to root it but unfortunately all attempts to go any further have failed?
2. Considering that the Kobo Arc has the same SoC (omap 4470) as the Nook HD+, what are the chances of cm-10.2.1-ovation.zip working (as far as I can see this is the latest for the Nook HD+ - sorry I can't post the link)? Of course there can be all kinds of different drivers required for the two devices, but chances are that they could be both based on the same or similar OEM designs. At least could this be used as basis to create a Kobo Arc variant?
3. Has anyone tried the Nook HD+ image?
4. All things considered, what is the next step towards a working rom?
Kobo arc 7 rom needed
my kobo arc 7 crashed cause i install chainfire 3d and now it is bricked and stuck in boot logo i need the stock rom cause i don't have any backup. can someone please give a link to download the kobo arc 7 stock android 4.2.2 rom
RC Files and thoughts on Custom Kernel
Hi, I am a new user here and in my attempt to give a reply to this user in this development thread , I got some weird restriction.
Anyway I have attached the .rc files that exist on my device. The init.carrier.rc and init.environ.rc did not exist on my device. This device is a KOBO ARC 10HD.
In addition, I have also been playing around with the kernel sources for the 10HD in particular, and as you can see from the screen shot below I am currently running my own custom kernel build.
Frankly I do not know how useful a custom kernel is since many of the special features are so heavily coded. Take the cpu governors for example, the way in which the cpufreq features are implemented make adding governors somewhat useless. There is a tegra cpufreq driver that parks the device in userspace, and decides based on the user interaction which governor is used. I suspect this has to do with the power saving features built into the stock ROM as well. In essence if I add let us say, a new governor, even if I select it as my preference the tegra cpufreq driver still has control, and defaults back into userspace once again.
Releasing userspace control of the CPU, GPU, and Cpuquiet parameters [Kobo Arc 10HD]
As some of you may have realized, it is impossible to successfully change some cpu, gpu, and cpuquiet related settings (ie. governors). This is due to a unified user daemon running in the background that constantly monitors and regulates the cpu, gpu, and cpuquiet (hot plugging) components. This means that you cannot change any of these options without them being immediately changed by this unified user daemon in userspace.
I had initially thought that this restriction was the result of a userspace kernel implementation, but it is simply a really annoying daemon messing with the kernel parameters.
To disable this functionality cleanly rename "/system/bin/ussrd" to "/system/bin/ussrd.bak" so that nvusd cannot initialize it.
This gives you complete userspace control over all cpu, gpu, and cpuquiet parameters! Do not touch the ussr_setup.sh, or you will lose important permissions to certain parameters. Do not do anything crazy like set the min and max frequencies to 51 MHz! The power saving features still work!
Good luck! Tell me if this solves your governor problems . . .

Hello everyone
I have succesfully compiled a kernel for the Sony Ericsson Live with Walkman and for LG Optimus L3 but I have some questions about modifying it.
1.Are the governors specified for one device or I can use a governor for any device.
2.Where can I find patches (ntfs read-write,otg support,ext3-4 support etc) and governors (smartassv2,ondemandx).
3.Is there any way to make my kernel support GPU oc.
4.How can I improve 2d/3d performance like many kernels do.
5.Where can I put the modules in ramdisk so the user doesn't need to flash them.
Please answer me as many question as you can.
No one????

I just found a way to overclock the GPU on all xperias. Need some testers, but remember, it might damage your device!
I will releasing here test kernels for X8, but these MIGHT DAMAGE your devices, so you flashing on your own.

Created 2013-11-05

I compiled the first version, but have probably a bad ramdisk, not even the logo shows up and gets into bootloop.
I need nAa-jb-06 ramdisk. @nobodyAtall Can you share it with me ?
Thanks.
1. We need a "little bit" more information about this project
2. The kernel is GPL protected, need the source (to identify what is your work and who worked with the kernel earlier)
3. The "original development" section need at least one idea what not exists on this device.
4. The "GPU overclock": with the msm7x27 SoC, the GPU clock is LOCKED, always run on the axi bus speed, you can't set it separately. You can set the GPU speed if you play with the axi bus speed in the acpuclock.c, but this is not a new idea.
5. The overclock of the GPU in our msm7227 SoC is theoretically unusable, because our adreno200 is cpu limited in most case. Just check the same gpu in the qsd8250, and you can see, with more powerful cpu this gpu can perform much better (on same clock)
This is NOT an offense, I just point to some thing before tons of idiot questions arrived about the project.
So, better if you correct the opening post and give the required informations, and folloew the forum rules (before you get a warning from a moderator, for example: due the missing sources)
PS.: you can cut the ramdisk from the precompiled nAa-06 kernel. I you have the knowledge to make new gpu overclock method, this is easy work...
PS.2.: Okay, just find the lz4 header in the kernel.sin, and delete everything before this and you can get the original nAa-06 ramdisk
Last note: maybe I wrote incorrect informations, the more experienced members/developers can correct it.
EDIT: the to overclock the gpu on all xperias is nonsence, because the xperia family have different gpus. (the most is adreno powered, but the phones with novathor SoC have Mali 400MP, or the xperia C have PowerVRSGX544)
I don't understand this kind of thread , first test then post it and do a favor for all do not create it in original DEV section this is not belong here .
Thanks whore?

I don't knew that. Sorry
Topic to remove.
Yet again this highlights the fragmentation of development here.
@op - I you had performed a search or even browsed here a little you would seen active kernel development.
You unwillingness to ask to join such a group of guys or even just post in their threads to contribute leads me to thinking you're a glory hunter.
And then when you ask nAa to just send you his ramdisk I honestly nearly wet myself.
Thanks for the laugh chap - I'm even gonna thank you for it

Hello,
awesome stuff man, great work.:good:
I'm just having one issue. I have to enable S2W,etc. in your application after each reboot.
Is there any way how to enable S2W, L2W, etc permanently?

usb audio
I so hoped for a new kernel but all the same "good news" (
nobody needs quality sound in phone.
device is protodug (dual-sim)
I compiled with make infinity_defconfig
compiled snd-hwdep.ko, snd-rawmidi.ko, snd-usb-audio.ko, snd-usbmidi-lib.ko (this is USB AUDIO in ALSA)
after inserting USB DAC it crashes and reboots. As 3.4.0
Does it needs some coding/recoding or Im just doing something stupid wrong? (it could be possible -)
Thanks
Is it uV set by default and how to check it? Please reply

wifi doesnt work after disable htc perf lock
i know this question is not for this thread. But Plz
i compiled a (stock sources from HTC) kernel For Htc desire x Dual Sim.i disabled perf lock by 'make menuconfig'After compilation i flashed kernel Then Wifi Doesnt WOrk. i used latest linaro toolchain.
Should I remove manually that line from My config?
Any Help Will Be Appriciated
I'm going to flash this infinity kernel. But by doing some reading about flashing kernels I really want to confirm some things before attempting to do this.
1. Is this kernel compatible with HTC desire X single sim running jelly bean stock ROM
2. Can I flash this kernel from twrp recovery.
3. Has it got OTG Support.
4. Can I revert back to stock if anything bad occurs.

Flashing the Kernel for Kittak
Hi,
I follow the explanation about how to flash the Kitkat ROM and Kernel as it's shown in ZTE Blade L2 Facebook Official Website. After the Kernel images appears my device stops. ¿What can I do?
Thank you in advance.

This thread is for developing of the ZTE Blade L2 kernel for Kitkat.
This is only the beginning. I'm not very comfortable yet with this part of development. Any suggestions or help is welcome.
Notes:
*Only tested in Stock Based Rom
Linux kernel version: 3.4.67
Development version: 1.0
Features
-Memory Swap. (SD Card is now recognized as Internal storage) ->Screenshot
Change Log:
-Edited fstab files to swap the internal memory and Sd Card.
How to flash:
-Flash it in the recovery. No wipes needed
WARIING: DO NOT MIRROR THIS KERNEL. DO NOT USE THIS KERNEL IN YOUR ROMS WITHOUT MY CONSENT. IF THIS IS NOT RESPECTED I WILL NOT SHARE ANYMORE DEVELOPMENT ON THE ZTE BLADE L2
Download
Source code
All sources can be found in my Github repository: https://github.com/DeviRSilva/KernelZTEBladeL2
Credits to developers
I want to give credits to the really good developers around, they gave me will and inspired me to search and dig more into the MTK world.
A special thanks to:
*bgcngm (for packing the scripts to unpack the kernel) ->http://forum.xda-developers.com/showthread.php?t=1587411
Disclaimer
*** As always - Flash on our own risk! ***
Make sure you flash it correctly!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in CWM recovery and safely store your personal data before you flash a new kernel.
Enjoy, and don't forget to thanks

Hello, sorry for taking so long to answer, you might want to reinstall a kitkat rom and right after isntalation install the kernel.. DOn't forget the wipes before installing the rom.
Recovery
Can i install this with the stock recovery?
No, only with custom recovery
Need your help please phone soft-bricked
Hey, i really liked the idea of that custom kernel, its the biggest problem i have with this device, lack of space to install apps. This was my last resort as i did all sorts of tinkering before i flashed it. The flash was successful and i rebooted and saw your splash screen but then my blade screen just goes dark the light from the lcd is still on but nothing more it wont boot to the os and i didnt remember to make a backup. Is there anything you can think of that would help me?
Please i really need to get this phone up and running again

Reflash with Flash tool stock firmware!
I’ll start by admiting that, in the arts of cooking/building/porting android innards, I’m closer to being a complete noob than na intermediate user.
I own a Newman K1S, JB 4.2.2, MT6592, 2Gb/16Gb, 720p, and, sadly for me, it looks like the manufacturer (Newman Mobile, or Newsmy, who knows) pretty much disavows any knowledge of this model ever being built or sold. No reference to it, no community, no android updates or ROM releases.
Taking into account some MediaTek source codes for KitKat were made available earlier this year (even if unofficially), I was wondering:
So, question number 1 – Is it possible to build android 4.4 for my device straight from said sources? Or are they unreliable and it would be best not to attempt it?
And question number 2 – Being at the noob level, should I stay away from such a task? And, in this case, would I be better off porting a 4.4 ROM from a similar spec’ed device?
Also, while browsing needrom, I noticed that a 4.4 “official” ROM was posted for my device. However, having flashed it, I found that it produces no sounds from the external speaker (although with headphones it works fine). Same thing was experienced by other users, and there is no fix so far.
Which takes me to question number 3 – What may I try, in order to fix an issue like this? Does KK use the same sound drivers as JB, and maybe it’s only a matter of replacing them? (if so, I believe this is within my grasp, even if I must unpack the IMG files to reach the drivers)
Lastly, Newman K1S has a severe overheating problem when pushed, which I believe would be easily solved by underclocking it to 1.3 or 1.5, or maybe implementing an optimized kernel.
Final question – How do I manage to underclock with my current kernel, or, better yet, how do I port a custom, optimized kernel to my device?
Congratulations to everyone who managed to read this far, and thank you in advance for any help provided. I’ve spent the last few days reading tutorials and guides, only to become even more confused… I did manage to get android kitchen running on my Windows laptop, though!
Links to recent/updated guides that might be useful are appreciated, too.
