[Nexus 7 (2013) Q&A] n3mmr:
Suppose one has a small set of requirements for changes to make one's Nexus 7 useful for a particular requirement.

How does one go about finding the right modded kernel/rom combination for the job??

My current requirements are, as far as I can see from my initial considerations:

The OTG charging mod, i e it must be possible to charge the Nexus 7 2013 using high current while using the USB connector in OTG mode.

I need to be able to mount a large (32GB or more) NTFS or FAT32 USB stick inside the normal file system, so that any app can use the stick for file access and storage.

I need to be able to use a class compliant two-way record/play USB Audio Interface, and/or use something like the Audio Evolution Digital Audio Workstation app for field audio recording in pro quality, while simultaneously using a USB stick for storing the recorded audio.

SO, how would I go about finding workable kernel, rom and add-on-apps to enable this on the Nexus 7 2013 WiFi tablet?
[Nexus 7 (2013) Q&A] Rahul721:
The ElementalX kernel has OTG charging built in and will work with Ntfs/Fat32/exFat
[Nexus 7 (2013) Q&A] n3mmr:
Well, yes, that answers my current specific needs, possibly. Thank you!

(BTW what ROM would you recommend for use with the ElementalX kernel???)

However, what I asked was more about a general method of finding a kernel+rom suited to some random specific need.

Is there a list of what kernels and roms do? Is there some part of the XDA site where this kind of info can be found??

Is there some part of XDA or somewhere else where people test kernels+roms? To find limitations?
[Nexus 7 (2013) Q&A] Rahul721:
As for the rom do you prefer speed or customisability?

If you mean how kernels perform with each rom you can find that in the Kernel's thread

:good:
[Nexus 7 (2013) Q&A] madbat99:
Each kernel has its own thread that tells exactly what it does and then users and the developer discuss all of it throughout the thread.
[Nexus 7 (2013) Q&A] n3mmr:
So you're saying there's NO rational way: You ALWAYS have to wade thru massive amounts of partly unrelated text, not all in any sort of reasonably obvious place or in any sort of rational structure.:cool:

Well.

Or ASK outright, and hope somebody just happens to have given the same question some thought recently??

Ah well. Forums, I guess. :)
[Nexus 7 (2013) Q&A] LinearEquation:
ElementalX has a caf kernel and an AOSP kernel. Thus you can use about any ROM you want with it just so you choose the correct corresponding kernel. There are a couple of lists that list many of the ROM's, kernels, recoveries etc. but there is no list that goes through each function of every ROM. That would be near impossible to keep up because devs change their builds all the time. AOSP might add or remove functions and now the devs have to work around it. There is just to much change to realistically keep a list like that and have it be accurate at all times.

Hi every one,

first, sorry for my english. I'm french.

I root my Kindle fire HD with this tuto: http://xdaforums.com/showthread.php?t=2069117

Then, I intall Playstore with this tuto: http://xdaforums.com/showthread.php?t=2069329

Finally, I install Go launcher HD with this tuto: http://xdaforums.com/showthread.php?t=2069668

But I have only black screen and no wallpaper.

I know it's a know issue, and I try to apply this fix: http://xdaforums.com/showpost.php?p=42181794&postcount=75

But when I try to launch the RunMe.bat and choose the first choice, it say me:

"Your system partition is too low on disk space to complete the procedure, please delete your alternate launchers, widget picker, and livre wallpaper chooser if installed and try again".

I do that, I uninstall go launcher Ex and HD and every thing from the system/app folder, but it say me the same thing everytime. I really don't know How I can apply the fix... :/

My kindle Fire HD is on version : 7.4.8

Thanks a lot for your help! :)
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
This is a problem that happens when the system partition doesn't have enough space to safely install the fix, anything you added to the system folder should be uninstalled temporarily. If it was not for thisnpritective measure you would have had the device go into a boot loop. If you can verify that your device does have enough free space on the system partition(around 30-35 mb if I remember correctly) then technically you can modify the script to disable the failsafe pretty easily. Run "df /system" from a adb shell or terminal to find out how much so pace the system partition has free. Personally I recommend just flashing a new ROM over the amazon os because they are so much better but if you want to stick with amazon os then I will try to help you out with the wallpaper fix.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
Thanks a lot for your response!

It was that. Too mucuh stuff in my app's folder.

I clean it a bit, and the fix has began and succesfully finish.

But no wallpaper... :/

Just a black creen like before.

I try with wallchanger, but nothing.

Hard way just for a wallpaper... thanks Amazon^^
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
You have rebooted the device right? If it still doesn't work undo the fix and redo it again, also clearing the dalvik cache can sometimes help.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
Yes, I have rebboted.

Automatically when the fix have finished, and again manually after.

I try to do it againt after cleaning, but I doesn't work.

I don't understand... :(
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
Can you be more specific? Did the script fail or you mean it applied it again but didn't work again?
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
The scripts finish and say me it finished successfully, and the wallpaper must now work. And the Kindle reboot automatically.

It say me to press key to finish, and the script close.

So I think, it's the normal process with the fix.

I try twice, but same result. The script say me it's good, but no wallpaper, just a black screen.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
Hmm wonder if there were any errors along the way I don't have failsafes in place for. If you could copy and paste the output into a post in code brackets I could tell if there was a issue or just use the debugger batch file. Read the instructions for it though or you will think it's broken. You could always just downgrade the kindle is with kffa or flash another ROM to fix the problem.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
Ah I see why the fix isn't working, its something to do with when it when it retrieved the framework-res.apk, or something of that nature because the file couldn't be found when it attempted to decompile.

To answer your questions about a custom ROM, I prefer stock cm personally, latest version is cm 11. I don't know too much about what's possible with the amazon market on the non amazon is. I think you can still read books, but forget about amazon prime movies and such. I'll check what the amazon app can do in a sec and edit the post. I personally son,t own any books on amazon market so I can't personally test if I can read them, I mainly read manga on my kindle with the pocket manga app. The process to install a custom ROM is safe if you follow the instructions and check things like the md5sum of the bootloader ahead of time and such, but it is possible to hard brick this device. Main point, you probably wouldn't hard brick the device, as long as you check the bootloader's md5sum before flashing it the worst you can do is soft brick it and that's fixable with a fastboot cable. The process is fairly easy and automated if you use the fire flash app.

Edit: OK so I think you can use the amazon app, I can neither confirm nor deny because my amazon kindle app is crashing at launch. I think it works on cm 11 though, I'm still on cm 10.1 because of I'm still having to figure out a way to keep my tablet ui when going to cm 11. Someone might post if they can use it or not because I am unsure. You can always flash back to amazon os, so I wouldn't worry about it too much.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
Ok thanks for your responses!

I'll install CM11. But, Must I really buy this cable? http://shop.teamblackhat.info/Factory-Adapters-motadapt.htm

I don't have, juste the original cable and sector in the kindle's box.

On this video, he don't use special cable: https://www.youtube.com/watch?v=PVuvR-hHOLE#t=14

is this proccess is safe? I guess, but I prefer ask you before make a mistake^^
[7" Kindle Fire HD Q&A, Help & Troubleshooting] stunts513:
OK I haven't clicked the link yet but I don't tend to use video tutorials, there have been a few hard bricks from people downgrading to a incompatible bootloader. You don't need a fastboot cable/adapter unless you brick it. Lemme grab a link for you. And I will check the video out to make sure its the right one while I'm at it.

Edit: OK well that seems to be the right video, personally I prefer this tutorial: http://xdaforums.com/showthread.php?t=2271909

Its pretty simple, and you don't have to verify the md5sum when downgrading the bootloadernsinc exit includes the file and I assume checks this itself. Only major steps I recommend are put the ROM and gapps on the sdcard ahead of time in case of a boot loop into twrp, and make sure you check the box off with red text around it warning about the bootloader needing to be downgraded. If you don't check the box that downgrades the bootloader then you are going to need a fastboot cable to fix the red screen brick that will result. Oh and another thing, the IMG link has not been updated yet to the twrp 2.7 build which is the latest, so when it says to grab twrp from that page, instead go here: http://xdaforums.com/showthread.php?t=2218796

Once you go there download the zip and extract the img file from it and use it instead.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
Ok, thanks a lot for your help. It's very appreciated!

So I wait your link for the good process to be sure everything will be ok.

I kinda put more into that post than I thought I would. I for some reason can't stand YouTube. I mean its great on occasion but I think I grew to dislike it from people constantly sending me instant messages with YouTube links back in the day, annoyed me so much that I grew to dislike it... Kinda funny if I think of it that way.
[7" Kindle Fire HD Q&A, Help & Troubleshooting] wine_00:
Ok, I'll follow the tuto wich you gave me in link.

But, in the introduction, Seokhun wrote:

My kindle is on version 7.4.8. Is there a problem with that?

EDIT: ok I confirm, the tuto is very clear and easy to follow step by step.

I've been very careful and I've follow the written tuto with the video tuto in the same time to read and watch step by step to do no mistake, and It's perfect. Everything works perfectly!

CM11 is installed, no problem!

Thanks a lot for your help stunts, without you, I'll still be in the sand... :(

Great forum and great community! :)

I was running PAC-ROM and updating regularly to the latest version. Last version was April 16th.

The phone was working fine but all of a sudden for no reason it rebooted and was stuck at the PAC Loading screen.

I realized something weird was going on so I went into TWRP to reflash but it wasn't able to mount any of the partitions... NOT GOOD @#$# so all writes failed.

So then I decided to ODIN back the 4.3 stock rom (from sammobile).

If wrote for about 15 minutes and then FAILED.

Can anyone provide me with a Bell S3 16G PIT file ??

I was able to find the AT&T version but couldn't find anywhere if this will work on my phone.. I did read that it didn't work on a TELUS phone so I'm reluctant to try it.

Erase nand
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] the.teejster:
Not quite sure I understand all your feedback but I'll try to respond.

- Corrupted tar file : The file I have is good as I have used it before. I downloaded again to err on the side of caution and MD5 was the same for both so I know the file is fine.

- Easy Nand : I assume you mean "Nand Erase All".

From what I read this is only useful if the partitions are stuck in read only mode :

Sometimes when you flash a ROM (TouchWiz or AOSP), there is a risk of the /system and /data partitions not wiping correctly thus leading them to be formatted with R/O permissions rather than R/W. This makes it impossible for the phone to boot up because no data can be written. Not even a typical ODIN flash back to stock or rooted stock will fix this. Using CWM to flash another ROM will yield the same no boot results.

In my case, when I started out, TWRP couldn't even mount ANY partition which tells me the PIT is corrupt or missing.I think I'm back to requesting a BELL SGH-I747M PIT file... sigh...

Thanks for taking the time to reply and for any additional insight you can offer.

I'm starting to think that my internal memory is simply toast but will continue to try.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] the.teejster:
Folks,

Apparently the PIT file can be generated on a rooted device by running the following command in the terminal emulator :

dd if=/dev/block/mmcblk0 of=/sdcard/out.pit bs=8 count=481 skip=2176

This should generate a file named "out.pit" in the /sdcard folder.

Can anyone with a Bell 16G S3 run this command and upload the out.pit file here please ?

I think the only possible way to move forward with an S3 PIT file is to "find" an official Samsung file that has the correct signature embedded.
