Has anybody seen significant improvements to battery life after rooting it?

I'm only interested in improving that, and am wary of rooting. Think it's worth it?

yes it's worth it, if you uninstall the hogging system apps

could anybody help me creating a working recovery.fstab?

I need it for compiling Clockworkmod Recovery.

it should be something like this:

/boot emmc /dev/block/mmcblk0p1

/cache ext4 /dev/block/mmcblk0p2

/data ext4 /dev/block/mmcblk0p3

/recovery emmc /dev/block/mmcblk0p21

/sdcard vfat /dev/block/mmcblk1p4 /dev/block/mmcblk4

/system ext4 /dev/block/mmcblk0p26

maybe Paul could help ?

@jaapstreepjan

I am glad you are working on CWM for the Liquid Gallant. It is important to have this tool

for nandroid backup and it is the base for future custom ROM, if any.

Apparently the first thing is to get the partition mapping and mainly the /boot and /recovery

in the phone.

As a simple user, I gathered some information below.

There are some interesting script/applicatoins for online nandroid backup:

Online Nandroid backup script :

http://forum.xda-dev...d.php?t=1620255

Currently for the Liquid Gallant, the right command line script is:

onandroid --phone --old --storage /mnt/sdcard2

but of course it cannot find /boot and /recovery.

Online Nandroid backup Android application using the above script :

https://play.google....r3t1c.onnandbup

The Android app is interesting since it updates automatically the script,

and optionally installs utility like makeyaffs if missing on the running phone.

Currently it uses /mnt/sdcard per default as storage and hence fails since there is not

sufficient disk space. And since there is no patch file yet for the phone, it cannot

find /boot and /recovery for backup.

For nandroid backup for Liquid Gallant, there are particularities to be considered:

- /mnt/sdcard2 is the external SD card where nandroid backup should be stored.

- /mnt/sdcard is to be backuped

- /mnt/sdcard/.android_secure is empty, maybe sec_ro to be backuped ?

From the scatter file (number of sectors for each partition), from the size of partitions dump using 'dd' command,

from the size of each file from Acer_AV041_E350_1.000.08_EMEA_FR.zip, one probably could

deduces a right mapping.

So if /boot is mapped to emmc /dev/block/mmcblk0p1, there is probably a problem

since this partition has only 1 KB (result of dd command), and boot.img size is 3660KB.

Happy to see that my FTP is used :)

Greetings to the forum, and specially to Vache. I'm a reader of this forum more than one year ago and this is my first post. I've learned a lot here and wanna thank to Vache for all good things done whith my Liquid MT. I still use it on ROM Gingerounay 3.1 and works great, better nowadays just with a couple of tweaks more.

This has been the reason to upgrade to Gallant Duo bought @ Expansys website, after being sure to reach root (thanks Paul)

but now I would like to see something like Gingerounay on my new Gallant Duo.

Of course we need CWM for it, and maybe anybody will go on as well......

I've tryed to download sdcard_update and the other file (i guess is the image of original OS) but got network failure at 10%

When finnally downloaded (will try again later) how do we handle this files, with flashtool or from sdcard?

I hope will finish both downloads... ACER_AV041_E350 is reaching 30%

Regards,

Neticus

Gallant is great for 200€, and I think just few tweaks would make it even better.

Hello,

There is a difference in the scatter file from Acer and from Modaco.

Is it important?

From latest Acer's ROM (OS_Acer_E350.1.000.18.EMEA.FR_A40I_A.zip) :

MT6575_Android_scatter_emmc.txt

__NODL_BMTPOOL 0xFFFF0050

From Modaco:

MT6575_android_scatter_emmc.duo.modaco.txt

__NODL_BMTPOOL 0xE89E0000

Thanks for the guide! I just flashed my phone with the ROM from vache's server. I already rooted my phone before but this time i want to try your method to keep the system update function.

However i have a SOLO version not a DUO and the scatter file says it for DUO. Just want to make sure i can also use this scatter file to flash my SOLO gallant?

Oke, didn't want to gamble on trying the flashing root method, so i just rooted my device using the Bin4ry method.

However ROM toolbox for some reason cant set my governor to on demand anymore like i used to :( (like with the previous rom).

Could this be related to the new ROM?

Nope tried that one too, just to see if it wasn't ROM Toolbox that was messing up. Are you using the French ROM too?

Thanks i'll give it a try, but dont these tools all do the same thing in basicly the same way? ROM Toolbox did work for me before...

EDIT: Just installed System Tuner, but also noticed there was an update for ROM Toolbox which i installed. Figured i'd give ROM toolbox another try first, and of course... now it work :D

Weird stuff. Maybe it just needed a couple of reboots. Maybe it's the updated version. (didn't mention anything in the "what's new" section about something like this) Either way, it works. :) Me is happy again.

Paul, I work in China and learn about "Acer Liquid Galant Duo" while being here. A bit more research - China's version is called AK330. Got one for myself and the problem I run into - I cannot install Google Play and add it to the list of my Android devices. Run into your topic, but cannot locate how to make a backup from my device. I do not need a brick in case I make a mistake - first time flashingexperiment for me.

Can you help me and give a link on your site to making ROM Dump (if it is the correct term) (backup) or link to the manual for Flash Tool? Spent 3 hours looking for those. no luck yet...

Thanks,

Mike
