Rom developing
It is possible to root the acer liquid Z3 (Z130) as well as installing TWRP. I'm about to develop Cyanogenmod for it. I hope that admins will give me a thread to start posting instructions:
Howto root it: root it using the app framaroot: http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276
Howto flash it with TWRP: Install and execute rashr and flash recovery with TWRP:
https://docs.google.com/file/d/0B0XQigIT17uEcDQtaDJ3U0UtOWc/edit?pli=1
The kernel source is availible at http://us.acer.com/ac/en/US/content/drivers
The supposed procedure in getting the z130 specific image is (excerpt of kernel source readme):
Build steps:
1. Download Android 4.2.2 source code from google
2. Modify buildGPL.sh, replace the Your_Toolchain_PATH with your tool path in android code.
for example: android/prebuilts/gcc/linux-x86/arm/arm-linux-androidYour_Toolchain_PATHeabi-4.6/bin
3. Run the script under your shell
./buildGPL.sh
Thanks!

I'm happy if I get a companion while developing. If you're new to cyanogenmod you can start with:
http://wiki.cyanogenmod.org/w/Build_for_a700#Build_CyanogenMod_and_ClockworkMod_Recovery
Give me a thread and device section !

going on
My main motivation in getting cyanogenmod running is to get a german android system language. Since I bought the Z130 in the Phlippines
it only came with English and a couple of Asian languages. None of the language programs (morelocale2, locale, Sprache) could change the system language to german even while rooted. Today I tried to flash a system partition of the Acer homepages' Update images, namely the OS_Acer_AV052.Z130.1.007.00.LA.GEN1s_A42J_A
TWRP worked fine, but it didn't boot. I could rescue to the old system.ext4.win after the Acers' image failed.
I already contacted Acer. Maybe they will at least tell me which image has the german system language and works with the dual sim kernel... I'm still considering cyanogenmod's images though.
I added some detailed german instructions on rooting the liquid z3 and installing TWRP: http://www.wendenerp.de/Sonstiges.html
So far,

i have the single sim version with european languages. i wish i could get some asian languages on this phone X)

I started a cyanogenmod project on github for the Acer liquid Z3: https://github.com/wendenerp/android_device_acer_zx. I had some trouble with the local manifest file, but I think this should be alright:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="wendenerp/android_device_acer_zx" path="device/acer/zx" remote="github" revision="cm-11.0" />
</manifest>

Next thing is to get the vendor specific programs and drivers out of the original firmware...

I'm having some problems with getting the ramdisk image out of boot.img.
The boot.img is 6 mb in size. I tried unpackbootimg, unmkbootimg and split_bootimg. All of these tools split the same way:
The kernel gets 4mb and the ramdisk 600k, which adds up to 4.6mb. Additionally the ramdisk is of file type data:
Code:
file boot_img.lzma
boot_img.lzma: data
so neither gunzip nor lzma -dc works to extract the initramfs. I assume there is a bug in all of these split tools or acer made up some strange boot.img format...

---

boot.img split error
Unfortunately the split utilities don't split the boot image correctly.
The image should contain the size and location of the kernel and ramdisk inn the first bytes of the boot.img, but this is how it looks like:
Code:
[email protected]:~/Android-Hacking/z130_full_backup$ hd boot.emmc.win |grep 'ANDROID' -n4
1:00000000 41 4e 44 52 4f 49 44 21 58 36 3d 00 00 80 00 10 |ANDROID!X6=.....|
2-00000010 34 bc 09 00 00 00 00 11 00 00 00 00 00 00 f0 10 |4...............|
3-00000020 00 01 00 10 00 08 00 00 00 00 00 00 00 00 00 00 |................|
4-00000030 31 33 37 37 37 30 33 33 30 39 00 00 00 00 00 00 |1377703309......|
5-00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
The split_bootimg.scrip takes the values out of the first too rows in little endian to determine the sizes and locations:
Code:
[email protected]:~/Android-Hacking/z130_full_backup$ ./split_bootimg.pl boot.emmc.win
Page size: 2048 (0x00000800)
Kernel size: 4011608 (0x003d3658)
Kernel location: 268468224 (0x10008000)
Ramdisk size: 638004 (0x0009bc34)
Ramdisk location: 285212672 (0x11000000)
Second size: 0 (0x00000000)
Board name: 1377703309
Command line:
Writing boot.emmc.win-kernel ... complete.
Writing boot.emmc.win-ramdisk.gz ... complete.
Unfortenutely the location exceeds the size of the boot.img:
Code:
[email protected]:~/Android-Hacking/z130_full_backup$ hd boot.emmc.win
...
0046fc30 00 81 11 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
0046fc40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
*
00600000
So it looks like the scipt only pulls some random data from the memory for the kernel and for the ramdisk
In fact the ramdisk starts at a different location:
Code:
[email protected]:~/Android-Hacking/z130_full_backup$ hd boot.emmc.win |grep '1f 8b 08'
00005220 6e 20 65 72 72 6f 72 00 1f 8b 08 00 00 00 00 00 |n error.........|
003d4200 1f 8b 08 00 00 00 00 00 00 03 ec 7d 0b 7c 54 c5 |...........}.|T.|
All 3 split utilities do the same:
unpackbootimg, unmkbootimg, split_bootimg

since the bootloader is u-boot I think the image has a different format:

progress
I also was able to extract the ramdisk out of the boot.img and added it together with the mkvendor.sh output at github.
I was also able to compile the kernel from sources provided at acer.com. I requested the sources of the u-boot image too.

You are doing great job dude keep going )))

U-Boot Source Code request
This is my request to Acer for the U-Boot source:
Dear Sir/Madam,
thank you for your reply. Software licensed under the GPL2 can be reused and modified and sold with the restriction of handing out the source and build instructions for the sold product.
In case of the Acer Liquid Z130, Acer has aquired and modified the following Software:
Linux Kernel, the Android OS, the U-boot bootloader, of which the linux kernel and U-boot is licensed under the GPL2, meaning that acer is obliged to hand out the source code of its modified U-boot and the modified kernel plus the build instructions. Since Acer only handed out the instructions and source of the modified linux kernel on its webpage, it hasn't yet met its obligations.
Since Android uses a different licence, you can refuse to hand out part of its code but you can gain popularity in the opensource community by doing so.
Yours sincerely
Denis Wentland
The request dates from 3th of July. How much time to give them and how to proceed in case they don't follow?

U-boot
While investigating usb-traffic, I encountered some CDC-ACM messages on the powered off, battery removed, usb-connected device . For 1 second the device opens its USB serial port and spams some READYREADYREADY messages . Then it closes it for some 8 seconds again.
On factory mode it asks for the input password on the /dev/ttyACM0 port.
I hope I can find out the password and enter U-Boot command prompt.
Since U-boot is under GPL Acer should hand out the source for me to find out the pasword.
hexdumping the boot loader firmware it has some uboot-messages:
000277f0 2d 20 0a 00 5b 25 73 5d 20 55 6e 70 6c 75 67 67 |- ..[%s] Unplugg|

but unfortunetaly not the Serial output messages

I have a french Acer Z3 Single SIM and as many on XDA i am a kind of flasholic.
I found a file .ZIP opened it and found boot.zip, system.img, recovery.zip that I I flashed from ADB\Fastbboot.
Was able to boot the phone but it’s from dual SIM update Thaï operator.
This one : Update_Acer_AV052_Z130_1.005.00_AAP_AISH https://www.dropbox.com/s/5s07i8g1hq3ekga/Z130SingleSIM_Tha%C3%AFSTOCK_ROM.zip
I don’t get any network signal from it. If it can help…maybe?
WARNING: if some of you decide to dowload this, please do not install it on your phone, because you will not be able to install another System.zip. Or unless you want an asian DUO SIM THAÏ Operator ok! :good:
