Need Some Help OTG + Charging - Nexus 7 Q&A, Help & Troubleshooting

Hi,
Total noob here, I've been reading alot but a bunch of it is way over my head, and i can only watch so many videos. PLease break it down "barney style" for me...
So i have a Nexus 7 2012 Wi-FI + 3g, its unlocked, rooted and running 4.4.2 with TWRP 3.0.2.0 via the Nexus root tool. I have a OTG cable to be able to charge and use an external hard drive, and from what i'm reading i need to flash a new kernel to be able to use that. I've found Timur's kernel works to accomplish that, but i can not find that kernel, and he's stop hosting it since Sep. 28, 2014. Does anyone have that kernel? Does it work with 4.4.2 and TWRP? Are there other kernels that i can use vice Timur's that allow me to use the OTG + charging? Also i do not plan to install this in my car.
Thanks,
Adam

Wifi Crash, Media Crash, Settings "Storage" Crash
Hey guys, I'm on PA 4.6 BETA5, when I flash the aosp or franko kernel (after going back to stock kernel before flashing the new one) my Wifi won't enable, android.something.media crashes and in the settings app, when I tap storage the app crashes...any way to solve this problem or an alternative? Thanks!
PS: I'm really sorry if this was asked before, I read the hole last 10 sites of the forum and didnt found anythings related to my problem, "just" 10 sites because I think its related to 4.4.4 and maybe PA.

There are custom kernels (unleased kernel series, Hells Doctor, Hellscore, ...) which supports OTG and also supports Lolipop.
Stock Lollipop

mm okey! so, have you test Hells Doctor on Lollipop? I will try out it this afternoon. I'm running a 4.3 stock perfectly with the otg, but Lollipop look like so excited.
Lollipop

How does one "Simply install the zip in recovery"?
My screen is broken (just the touch; everything is still visible). I was hoping I could install this mod without being able to touch the lower half of my screen so that I could plug in a mouse so that I could copy some files off my device.
I can reboot into recovery mode, but USB debugging is *not* enabled. I've never used "adb" on this device before (I just says "offline" when I try to run it from my PC).
I have no idea how to "install a zip".
Phone is an Nexus 4, running android 4.something.

Is the OP willing to develop the patch for lollipop too? Or is there any nice kernel with USB host support?

What can be the problem, why OTG still doesn't work
Hey guys,
however I'm completely new to this stuff, I managed to get through every barriers, and I put Cyanogenmod 11 snapshot M12 on my Nexus 4 and after that flashed the suggested kernel and patch successfully to try out OTG. The phone works withput problem, the installations seem to be successful, therefore I tried to connect an external storage to the phone to check if OTG works on it.
For that, I used a SIMPLE OTG cable like this:
<<<LINK CANNOT BE SHOWN SINCE I AM NEW TO THE FORUM - picture is the second picture of the first post in this thread>>>
connected to an Y-cable SIMILAR to this:
<<<NO LINK AGAIN - the 3rd picture of the first post in this thread>>>
The difference from the one on the picture is that mine has a male mini USB end instead of a female normal USB end as in the picture. My cable is the cable of an external wichester otherwise.
So, I tried with this cable setup, the result was that both the phone and the connected storage received electricity from the external power source, but the storage was not detected by the phone. I had a feeling that it doesn't get enogh power, so I attached it to a USB phone charger just to be sure, but the situation remained the same: the light on the storage was green, which means it is charging, the light on the phone was also on, but the storage was not detected.
My question is if I should try with the exact same cable set that can be found in the first post of this thread on the first picture or mine also should do the job, and there should be still some software related problem?
Please also tell me if you need more information on this to answer it, however I tried to be specific.
Thank you for your help in advance.
Hello. What i can do on lolipop? There is no solution? I have a 32gb flash drive, y-otg cable, standart power adapter micro-usb-male. Rooted nexus4
Which zip I need to download?
Hi, i'm really beggining on Android stuffs, since I didnt had one until the last week, so I'm really in doubt about which one of the zip files i need to install in my system to make the OTG cable work properly.
Once I downloaded a random ziddley zip on the internet and when I installed it in recovery mode, i needed to reinstall the android system on my phone, since the phone wont boot anymore.
So, can anyone help me? I'm sharing in this post a screenshot of the Android Version screen on the settings. I've rooted my phone using the King Root app
Considering that my android version is 4.4.4, I consider that I may download one of the following:
4.4.x: 2013.12.11 1604ET: [fk r199] [fk r199-CM]
4.4.x: 2013.12.06 1445ET: [aosp r7]
But which one?
And just another noob question. Is this the right way to install the ziddley zip on my phone?

Sorry for the noob questions and thanks to anyone who helps, because I REALLY need the otg cable to work, so I can develop some things using the XBOX 360 cable!

[Q] OTG possible with rooted Tablet after USBHostCheckFix? (GalaxyTab4 7.0 | SM-T230)

Hey,
I want to ask if it's possible to use USB OTG when the Tablet is rooted after using a Tool like "USB Host Check" which can activate OTG on several phones/tablets?
Otherwise I won't root it and bring it back tomorrow.
I saw a lot of comments on OTG but actually no one really wrote sth. about rooting it and using such a tool afterwards with the new android version update. I hope someone can give me more information on that.
Greetings,
Cédric
Brought it back and took a Galaxy Tab Pro 8.4, for only 240€, instead

[Q] Kernels and ROM for Kegbot

Howdy XDAers,
So I'm currently in the process of trying to complete my Kegbot install. I have a Nexus 7 (Grouper) that was upgraded to Lollipop (5.0.2) and was following the instructions as given at <DEFEAT ROBOT>https://forum.kegbot.org/t/howto-root-nexus-7/203/7</DEFEAT ROBOT>. The problem is that post was written for the Kit Kat version of Android. And unfortunately the Kangaroo kernels they have linked to have been replaced by someone trying to install malware on my system (the nerve). So that was a dead end.
Anyway I am looking for a kernel that allows me to use USB OTG and charge my Nexus at the same time while on Lollipop. Does such a kernel exist yet? About 45 minutes of Googling has yielded nothing. If not can someone point me to where I can find a Kit Kat kernel with the aforementioned support and an accompanying ROM to go with it. I can handle the rest from there. Thanks gents (and ladies if any are in here).
[ EDIT ] : Spelling and Grammar.
Hi Stieg.
Did you ever figure this out? i`m in the same situation myself. just started my kegbot build but i am trying to run the server directly from the Tablet.

Looking for the right (kinda specific) kernel. Grouper, multirom, 5.1

Hi guys.
I've searched around the boards and net for days (cause what's worse than a new member that can't use the search function?) and I'm in need of a specific kernel for my 2012 Grouper.
I'm currently running Multirom with Kali Linux Nethunter (written over Cyanogenmod 12.1) in my primary slot, and CM 12.1 in the secondary.
I'm wondering if there is a kernel out there that will fill the following needs:
5.1 Lollipop (CM12.1, Nethunter 3.0)
Kexec-hardboot
USB fast charging/power external devices (TP-Link wifi adapter)
And if possible, All F2FS (I've found nothing for 5.1 compatibility with F2FS)
If I'm stupid and overlooked something obvious, feel free to call me on it. I'm new to Modding, and I've bricked my HTC Evo 4G LTE about 30 times without running to forums to ask for help on piddly and obvious solutions. As to the "needs" on my kernel, yes... I know I want pretty much everything. Hehe.
This forum has been a tremendous help so far, and I look forward to interacting with you all.
ETA: Current kernel version "3.1.10-Bricked-v0.591-g0a2e5f6 [email protected] #2"

More recent ROM similar to Timur's USB ?

I have a Nexus 2012 (Grouper) with Timur's USB ROM / Cyanogenmod 10.1 on there (my brother installed this - it's installed in the car).
I would like to upgrade to a newer ROM (Cyanogen 12?) but unsure of compatibility - every website I've read seems to be information overload (I'm new to android world).
I've been told I need a ROM that supports a Y-split OTG cable which runs into a powered USB hub.
The reason I'm wanting to upgrade is for BLE compatibility as I believe from what I've read, that this is possible on the Grouper with more recent versions of Cyanogenmod

I don't utilize OTG on my Nexus 7 at all so I don't have an answer for you. What I can tell you is that you should probably try what I did, flash them all. Also I don't recommend any rom above android 4.4.x due to the very "slow" nature of the Nexus 7
What’s is the newest one that is under 4.4?
