Custom ROM creation mentoring

Re: Custom ROM creation mentoring

So you've moved files in and out of the mount folder. You then need to unmount and check the file system (system.img).

You will then need to make the sparse image from the image you have. This is something I have no knowledge of but check the tool you used to make an image from a sparse image does it have options to work the other way? Is a separate tool available from the same source? Does the kitchen you have have options for this. It's late here in the UK so this is it for today. Look forward to hearing your progress tomorrow, hey you may even have someone who knows what they are talking about chip in with some help.:-)

You're right in regards to the system.img file-I totally forgot I 'mounted' and unmounted it-I copied the files (and the folder) off and got mixed up thinking I had to make an image out of that instead of the modified system.img so that solves *one* problem. So now I need to figure out how to 'redo' the part that I ran to extract the image (using the unimg command in the a10 toolkit)....fun...

Get some sleep supersport and thanks for the help! Hopefully I'll be able to reconstruct it by the time you wake up :-)

Ok, so I'm close (I think) to repacking it for use with livesuite. I just need a little guidance on what to 'repack' into the final image. I've included a list of the files that were extracted-do I just repack 'everything' or do I repack, just the recovery/boot/system .fex files?

Thanks!

Sorry, I've not used livesuite so not in a position to give good advice. Time for you to hit hit google for some research :-)

You never know someone may come along with am answer soon.

As ever good luck, the feeling of success on flashing your first custom rom and booting is worth the effort.

I'm tempted to take just the 'biggest' files but I don't wanna screw up my 701...oh well, google here I come!

LOL! Well attempt #1 was a glorious failure! I was able to build the .img file and I was able to even load with livsuite and flash to the tablet, but when I powered it on....nothing, however I have a sneaky suspicions I'm missing a file-I noticed that the post Shawnbusker originally made had boot.img, recovery.img, ROOT.IMG (something the kitchen didn't tell me to include) and system.img. I'm going to include that file (if I can figure out which it is) and try again.

Well, I'm stuck again. I've gotten 3 of the 4 files I need...I think the problem is with this whole bootfs/bootloader image. I can't for the life of me figure it out......ARGH!!!

PROGRESS! I figured out the bootfs garbage. I extracted the bootfs info from the tablet with ADB and was spinning my wheels until I realized I needed to paste that dump into the a10 kitchen _bootfs folder so *that* obstacle has been overcome. my ROM now flashes correctly but freezes on the stock "Internet Tablet" logo, so I'm guessing either the apk files I put in the /system/app are freezing it or perhaps I didn't change the permissions of the /system/ folder correctly (not sure that would make it freeze and not boot)...

[elektrik]

even more progress...somewhat... after reviewing Shawn's original email 'how he did it' for the GB dump, I realized I'm still missing this file: "bImage"....if I can just find it (downloading the Onda firmware now, in the hopes I can duplicate what he did)...

Is everyone sick of my posts yet? lol!

Re: Custom ROM creation mentoring

So the only files you have changed is system.img.

What I would do to check I had the flash side correct is make a backup of your new system image then replace with the stock system image and check this flashes and boots.

Did you do a file system check on your system image after you had completed your changes?

Exactly what changes did you make to system?

Yes, the only thing I changed at this point was the system.img. I'll try to drop the 'stock' system.img back in to verify it flashes correctly (didn't think of that).

file system check? um....how do I do that?

The only things I changed to the system.img were:
-changed permissions to /system/ and /system/app (For full root)
-added my own apk files I normally install
-removed all apk from the /preinstall folder

I'll go drop the system.img in right now to see if that works...

Have you read all of that thread on rk rom hacks, it's full of answers.

You sir, are a genius :-) dropping in the stock system.img worked-I was able to 'rebuild' the stock ROM so now I need to focus on just my custom system.img to see what's going bad.....

Maybe I'll take things one step at a time (Ex. 1. changing to add root, then 2 removing the preinstall folder, etc. etc.).

Get some sleep and thanks again!! now that I have a complete extraction/flash process maybe I can actually make some headway.

I can't believe it, but I actually did it (although with unintended results, lol!). I was able to make a rooted ICS ROM with a functioning google play (and my own apps) using the stock image. Wow, what a learning experience, lol! MUCH thanks to 900Supersport (and everyone else who read my manic crys for help!)....
...now all I have to do is learn learn learn! When I'm confident enough, I'll be posting how I did it in guide form (as soon as I can duplicate everything I've just done) and perhaps after some time I'll duplicate Shawn's original efforts to provide a factory rooted ICS ROM with google play enabled (with perhaps more customization to come....Hmm.... "Elektricity ROM"-it has a certain ring to it :-) )....

Congratz man. Maybe your next step could be install the custom boot animation. I think I would do small steps to begin with.

Good job.
