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.

I have made cwm 6.0.1.4/5 and twrp 2.2.2.1 Touch with porting from other device but need help for fstab in etc kernel.
Problem on backup is boot.img and recovery.
Boot emmc /dev/boot not ok.... same for recovery. I have try other but never backup boot and recovery.

Is possible for this device mt6575 bakcup all?



/boot emmc /boot ----> 0 byte
/cache ext4 /dev/block/mmcblk0p2 ----> 14 Kb
/data ext4 /dev/block/mmcblk0p3 ----> 482 Mb
/misc emmc /dev/misc
/recovery emmc /recovery ----> 0 byte
/system ext4 /dev/block/mmcblk0p6 ----> 460 Mb
/sdcard vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1

This is link of my porting of twrp 2.2.2.1 touch recovery ----> copy this file into Images directory and use flash tool. Look guide Using SuperRecovery - step by step of Paul

Here the link of this recovery mod.


I have porting this recovery from other chinese device with mt6577 ----> V1277.

This recovery is only for testing.

Tomorrow upload recovery CWM 6.0.1.5 touch and no touch.

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

Thank you for your post. I will take a look to this product, but it seems to be well supported (at least with software, ROM, root, CWM etc...). Also it is convenient for European buyers. Now I have to look in more details about the product specification.

As far as I understand, you simply use the Flash Tool but not the 'download' tab (which is flashing the phone), but the 'Read' tab (which is save/backup).
So you can backup all partitions.

Other maybe easier way is to go to Acer site, and download their ROM. There is a EUU.exe that takes care of flashing the phone from scratch. So this is not backup the phone, but resetting all the phone to original (up to the released level of the ROM). This should work even if your phone is bricked.

I am glad that there are people like you working to get a functional CWM recovery for the Liquid Gallant.
I will append more information, but I know (and tested) that Onandroid backup script can backup /boot :
Online Nandroid backup :
http://forum.xda-dev...d.php?t=1620255
Online Nandroid backup
https://play.google....r3t1c.onnandbup
has a patch file for the Gallant, and is having problem backuping recovery too (refer to execution log below).
Command:
'/mnt/sdcard2/MyBackups/scripts/backup_onandroid.sh'
=
onandroid --phone --old --storage /mnt/sdcard2

Hi hapx

i tried backup boot.img and i have problem.

----rwxr-x 1 system sdcard_r 5242880 Oct 26 15:57 boot.img -----> not correct.


For my backup i have used cwm 6.0.1.5 and if i use /boot emmc /dev/boot ---> backup on cwm stop here with error of boot.img but save this file same byte 5242880
I have take this file but not correct boot.img. I used tool for boot and recovery and HTC Android kitchen but not chance to open this file.

If i use partlayout4nandroid of onlinebackup i see this:


dev: size erasesize name
mmcblk0p1: 000020 000002 "ebr1"
mmcblk0p2: 10f720 100000 "cache"
mmcblk0p3: 20ff20 200000 "userdata"
mmcblk0p4: 410720 3328e0 "emmc"
mmcblk0p5: 009f00 002800 "boot"
mmcblk0p6: 00ef20 100000 "system"

But for me mmcblk0p5 is ----> emmc@sec_ro -> /dev/block/mmcblk0p5

Hello,

Some ideas and comments:
1) If at least we have a CWM allowing execution of unsigned zip, has busybox and su, and access to shell,
this would help a lot.
2) Then for backuping the whole system, maybe then inside the CWM we can invoke script (.sh) using something
similar to this : MTK-6573-BakUpTool.rar
http://forum.xda-dev...d.php?t=1683883
3) With point 1), at least backup and restore with 'dd' should be possible.
4) Maybe with the scatter file, the vold.fstab in recovery mode, the mount command result,
the updater-script and shell sccript (\recovery\etc\install-recovery.sh), boot.img and recovery.img from official ACER ROM,
developers would arrive to a working solution by studying them. Since the ROM shell scripts contain script instructions to update/format
boot and recovery 'partition'.
