ROM work for Archos 80 Cobalt?

[technaudio]

people will always argue.over whats faster, just like they whinge about battery life (for gods sake, you have a pocket sized computer!) but i dont give a toss about a few points gained on a benchmark test!

if i'd wanted cutting edge blisteringly fast tech, id have bought a device 3-4x the price of this one.

OK so maybe time for me to help.

Do you guys want parameter files for different setups of user space?

I'll probably be able to look at this tomorrow evening. I'll put my cobalt on charge and will be able to test flash. Can also look at swapping the sdcard too.

This parameter file will give 6 gig app space.

open the parameter file from my rom kit in a text editor and replace with this. Then do a full flash with erase idb. Will sort swapping the sdcards tomorrow.

For safeties sake make a backup of the parameters file

Here's the vold.fstab

this will make 6gb on /data? and external sd become /sdcard right?

quick question, with the way i swapped internal and external, i couldnt install xda app, it said could not install to sdcard or usb storage

[900supersport]

Re: ROM work for Archos 80 Cobalt?

Yes, not tried the xda app but had no problems so far with tappatak, Facebook and carbon.

[900supersport]

Re: ROM work for Archos 80 Cobalt?

I get a package file not valid error on the xda-developers app.

[technaudio]

ill just pull it off my phone and put it in /system/app that should work...

[technaudio]

Re: ROM work for Archos 80 Cobalt?

I'll have a go with this when I've got a bigger sd card to use, currently only got a 2GB spare one!

ROM work for Archos 80 Cobalt?

Nice! I've wanted the ability to use the external sd card as internal storage for ages now! I'll give this a try. Thanks 900supersport

Firstly, great thanks to 900supersport and the site for providing more valuable assistance with the Cobalt.


I've applied the parameter file will to give 6 gig app space and that seems to work well.


I also tried to apply the vold.fstab option but on booting the tablet sat on the start-up screen with loading ... flashing across the top of the screen and no further progress, so I'm not sure if I have done something wrong there but cannot get that to apply.


I've noted a few additional things about the new ROM:


1. Battery usage seems to be far higher and rather than getting up to 5 hours of general use, I am now getting less than 3.


2. The volume rocker switches are now reversed.


3. When performing a back-up using CWM to the external card, the process seems to run correctly but when I examine the contents, there are are 5 files:


boot.img (16 mb)
cache.ext4.dup (5k)
data.tmpfs.dup (9b)
nandroid.md5 (238b)
recovery.img (16mb)
system.ext4.dup (196k)


I would expect the backup to be in the hundreds of megabytes, so don't know what is preventing the back-up from completing successfully.


I did try the back-up to the internal SD but there wasn't enough space for it.

Re: ROM work for Archos 80 Cobalt?

I don't use the cobalt too often so have not noticed the battery issue.

The six gig apps space and vold where done and tested on the original ROM, again I've not tried this on the new ROM. It would make more sense to look at the vold I posted and compare with that on the new ROM, with a but of luck an edit on the two lines for the sdcard should see you right.

[bluesmanuk]

Thanks.

I followed the instructions in post 190 and that seems to have done the trick.

Hi,

I've flashed the custom ROM & works very well, but just been reading through these threads, would it be possible to have 5GB for APPS and whatever space is left for SD Card, reason being is the 6GB parameter leaves only 196MB for SD which is a little on the small side.

Thanks
