Hi guys im a noob to the forums and to rom customization in general looking for some help
I have a generic MX dual core, and have been supplied a flash firmware and image from the supplier. This image is basic and has a lot of bloatware apps which i want to remove and put some of my own
The image supplied is a zipfile and contains:
factory_update_param.aml
hd18d_mx4.zip
recovery.img
I am able to successfully restore my box with this image (so I know that the image is working fine).
Within the hd18d_mx4.zip there is:
Directotories: data, META-INF, recovery, system
files: boot.img, bootloaded.img, logo.img
I can see the all the system APK files within the system/app folder. The problem is when i try to add another APK file into this directory within the archive (in this case videomix.apk), I am not able to restore the image to the MX device.
Can anyone help me with a noobies guide to do this. I have read that the apk file has to be signed, and the zip file has to be signed also?? But im not quite sure what this means, nor how I go about doing it.
Any help or tutorials will be much appreciate. I have downloaded the APK-multi-tool but dont have a clue what I need to do
Look forward to your replies.
P.S. Im using a windows 32 bit machine
anyone???

Hi all,
I have a SmartQ ten3 T15 Android 4.0 tablet (TI OMAP 4430 SoC) on the way to me from China.
As I like to have all files on hand before gadgets arrive, I downloaded the standard firmware yesterday from the SmartQ website.
As I read somewhere (don't know where) that sometimes firmware files are zip files I renamed the extention-less firmware file to .zip and I could just open the file with winrar and extract the complete file structure of this ROM.
That got me thinking of creating my own ROM files, but first I'd like to have some questions answered by people with experience doing this.
Normal firmware update on this tablet is done via micro SD card, and by entering a boot option while holding down certain keys.
The questions:
- Is it as easy as putting in or taking out the files in the folder structure, zip the files and remove the extention and update it to the tablet?
- Winrar says the file is signed with signApk, but this also seems a very straightforward procedure to signing my own ROM's. Or will the tablet only accept files signed with their certificates?
- Anybody else have experience with firmware files for other devices who work the same way? And do you have tips for me?
One of the things I'm trying to achieve is getting bluetooth and FM to work, the hardware supports it but it is disabled by firmware.
And further on I would just like to customize the tablet further, by removing apps and adding my own and so on.
Thanks in advance for your help.
Hello all. I recently bought Final Fantasy IV and was disappointed to find there was no language setting in the game that I could find. Ideally, I would like to play with Japanese audio and English subtitles. Launching normally under USA locale plays English vocals and subtitles. I was afraid that the Play store variant would only come with English audio, but I found by changing my Nexus 7 language settings to Japanese, that it would in fact contain and play with JP audio and JP subtitles. I can't understand why , this being the case that there isn't an easy in application language switching option that I can see.
All the components are there. Does anyone know how I could somehow edit the files to play JP audio and English subs? Copy the JP audio track to the English version of the game seems the most straightforward , if I could figure a way to do it. Anyone have ideas for this process? Programs I will need to unpack the apk or game data and edit what needs to be etc...? Thanks.
To th ebest of my knowledge, it appears that I'll probably need to unpack the .obb file somehow. The .apk is small. Does anyone know of an suitable utilities to unpack and repack/sign if need be .obb an/o .apk firles?
I've seen a few posts on the forum suggesting that I simply rename the .obb to .zip, .rar etc... and it will simply be able to be extracted. Sadly, this doesn't seem to be the case. I've been attempting to use 7zip to extract the archive with a number of renamed file types and every time it claims that it doesn't seem to be a valid archive etc.... Others have suggested 7zip works for this in other cases, but I'm not sure why it is failing now. Do I need to use a specific program to see if it is a valid archive?
Edit: I also tried with WinRAR and to no effect - the same problem where it reports that there is no archive present etc...
At the moment I'm trying this with an edited/sideload ready version of FFIV 1.2.3 (which has both the .apk file of a few megabytes and the .obb of a few hundred megabytes), at least until I can pull the exact copy off my device. I'd really appreciate any insight. What do I need to open/extract the .obb and why is it not appearing with 7zip? Thanks.
I'm going to try and get another copy of the files from another source (pulled directly from my Nexus 7 or Nexus 4) onto my Windows PC etc...

Huh... I'm not sure how to help you too. Just a simple beginner. But using .zip or .rar worked for me. Just that the file names were all long and weird. Also, every file appears as a .file extension
open obb file
Hi,
did you tried to open *.obb using "jobb" application from Android SDK?

Hello,
I need to find a way to edit factory firmware:
1. insert one or two app to be preinstalled, and placed on home screen
2. change default ringtone
I tryed android kitchen, repack system.img file (which is one of many parts files of firmware i have to edit, like boot.img etc) then i edited just one thing, e.g background or place one app. And then I get stuck, i cant find way to restore system.img. Kitchen makes update.zip file..which cant be installed becouse of signature.. So my main problem is how to edit system.img? (unpacked or packed)
Basicly every advice is how to repack, open *.img file, non is to repack.
I have PAP4500DUO and A538 Lenovo. And Windows envirement. I am a rookie too.. :/
Hello!
I have managed to root the tablet and then started removing some apps with Titanium backup app. Unfortunately I accidentally deleted an app starting with syst.... - did not see the whole name. The tablet restarted and now there are no back, home buttons and slide menues from above, no multitasking. The Android version is 4.2.2. I have managed to install some hover buttons, CW custom recovery. Found the rom and downloaded it. I guess the app that I am missing is in system.img file? How can I extract /browse the contents? There are some img extractor apps but i cant find a valid link to download such. Is it true that if i find the apk and put it in the system folder the problem will be fixed? Please advise me what to do! I thought of flashing the device with mtk flash tool but i dont have a computer to do this with ?
Any advice would be appreciated!
Regards,
Kamen
Hello,
I have managed to extract the Systemui.apk and systemui.odex files from the system.img firmware file. Put them in system/app with the correct permissions, restarted - still not working! In the net somebody advised that I try deleting the .odex file and / or install the systemui.apk (installation fails) . No solution again!
Please advice!
