Anyone able to mod this app to run on KitKat? - Android Q&A, Help & Troubleshooting

Basically I want to modify the APK to AirMessage (an iMessage client for Android) so it works on Android version 4+ instead of 6+. I'm reverting to a basic Android LG Wine Smart H486 flip phone (beautiful thing) for a video on my retro tech YouTube channel, but also for life enjoyment And this would allow me to get my normal iPhone texts when out and about on the old Android.
It has proven impossible to root the phone. The few techniques out there do not work or lead to broken links.
Apparently telling an APK to work on a different version is just modding one file, but it has to be decompiled first, then Google signed after. I can send you the AirMessage latest APK on request.
Anyone up to the challenge?

Rooting:
If you have either:
1. Unlocked bootloader AND fastboot mode
OR
2. Unlocked bootloader AND device trees
You can make it work. Note, you risk bricking your device. If you can enter fastboot mode, report back.
Nvm, there is a much simpler method to get up and running. The app is foss so you can just fork, modify and compile. https://f-droid.org/en/packages/me.tagavari.airmessage/

I tried compiling and In order to use core library desugaring, please enable multidex.
Seems to be a compatibility issue from API to API. You're better off porting the whole repo to an older version.

I would suggest signing up for alpha of Sunbird, another iMessage client that doesn’t require any apple device.

Yes but so does AirMessage. Sunbird waitlist is over 120,000 people. I have AirMessage now.
That’s not the problem. The issue is getting it working on the 2015 phone.

[ONLINE ROM LIBRARY, GUI & Android TOOL for HTC PHONES]

We've updated a bit....
Download Link: [Here]
We now have a complimentary app on the app store for this A4D App.
What is A4D?
The goal of A4D is for us to move beyond just N1 make it an all in one flashing/upgrading/android utility. We just added a ROM library with MD5s. We are not going to be hosting the actual ROMs by themselves so if you report a dead link, they will be taken down (after a number of reports). You can also add your own ROMs as well into the library.
The ROM library will be supported by both Android and Desktop App. We are rewriting the Desktop apps so that we can do all 3 platforms in one, Linux, Windows, and Mac. You'll love the layout of the app. That's all we can say for now.
Oh one more thing. The android app won the best android app award at the Mobile in the Middle Hack-a-thon over the weekend in Chicago (on 3/6/2010).
I would like you guys to try out the app and tell us feedbacks. Also feel free to add your own ROMs to the Database and tell us how we can make the DB better. There a number of features we are trying to add as well. But with our full time jobs... things are going a little slower than we wanted. Sorry.
Requirements to run the app on Android: Amon_RA's recovery. That's what we tested it with.
Reserved
Reserved for Future Updates / Changelog
Can't wait to see if this is fool proof.
Add md5 check. Make it in this way: user have to enter/copy-past md5 hashsum from forum/site. Program calculates md5 of image and says image is good or bad. Also you can disable flashing with out this check. ;-)
good idea. Will do that. That will help with flashing screwed up downloads.
Hi
Thank you for sharing the application.
Does it flash the radio too? I mean CyanogenMod has two files a radio ROM and a CyanogenMod ROM. Does it flash both of them to the phone?
Thanks.
Radio flash is in there we took it out. May do so in the next release but radio flashing is dangerous (can brick phones) so...
Hey Lwin,
Nice concept man, this is gonna prove very handy for many peeps.
You've come up trumps again
So, this is a desktop application?
Does it flash ROM's from your desktop or copy them over and just run the commands on the phone for you?
I ask, as I'm having some problems flashing now, based round a slightly faulty Micro SD card. Does it store backups on the phone or on your desktop PC?
This program is written so you don't have to do command line commands. Everything else remains the same. If you are doing a Nand backup, it goes where it used to go.
I would recommend fixing your "slightly faulty Micro SD card" by getting a new card.
nice app for those that aren't familiar with cmd or jus pure...lazy lol
maybe the screens should be bigger as quite hard to see clearly whats available.
Pure Genius...
seraph1024 said:
Here is the GUI tool for unlocking, updating, restoring, flashing of the N1 (and in theory should work on all HTC androids).
Try it out and see if it is useful. The tool is made to help for people with very basic skills since the tool at this stage is a wrapper for the shell commands at this point.
Again, as usual, we take no responsibility for loss of sleep, loss of phone or screw ups on our side (due to app) or on your side (due to lack of ability to follow instructions).
I wish to make it more simple. We welcome feed backs.

Hey Seraph, This is getting better and better everyday.. How is your windows and android port.. Oh and don't forget there little buddy, I need you on my Mobility Team when we arrive to the scene.. Android and Audi... Almost there....
Edit: Okay, can't run on Mac, of course will in VMware, can you please make this mac native too... It would be great as per what MooMoo said, for all who are lazy...

But I don't use command line now. I didn't realise anyone did. Do you not just boot into RA Recovery and flash from there?

There will be a mac port sometime this week. I can most likely port to linux too but if you know linux and if you have to use wrapper, you have an issue
install issues
I tried to install it but got a system update required....
extracted the sdk to the folder C:\android-sdk-windows
extracted android4dummies and clicked setup
I get a pop up with the following:
unable to install or run the application. the application requires that system assembly system.data, entry version 3.5.0.0 be installed in the global system cache.....???
What do I do now?
Sounds like the app uses .NET framework 3.5.
So goto microsoft website an get 3.5 .Net Framework.

You do need .Net 3.5. It should have asked you, if not installed that as a prerequisite.
I went to MS and downloaded the .net 3.5 installed it (apparently it was already on my pc, so instead of installing I tried to repair it. no success....

Can you send us a screenshot.
Do not unzip into C:\android-sdk-windows. App will install SDK or search for the SDK there.
Unzip on your desktop or temp and install from there.
just to be clear, I unzipped adroid sdk and placed in the mentioned location. the android4dummies is extracted on the desktop and executed from there..
so should I remove the SDK and retry?

[Q] Signing ROMS

What all goes into signing a ROM, and why can't someone take CM and sign it as if it was from Samsung? I'm guessing it's more than copying and pasting a few files, but why can't this be done? In concept it sounds easier than unlocking the bootloader. Is it known where the files that contain the keys are? Are the keys for each device different?
PetersDrue said:
I'm not an Android developer. I'm learning C++, and I have decided to put off learning Java, although some of the syntax looks similar (except for the 100,000,000 classes required for a Java program. I do know Android is run from a virtual machine and is based off of Java and other basic knowledge.
Anyway, I love my Cyanogen Mod and I didn't pay attention to unlocking the bootloader when I first got my phone. Now I'm really missing CM 11.
I know the bootloader checks to see if the ROM is signed by Samsungnd only then will it allow the ROM to be installed. (I'm a computer and Android enthusiast, some more technical info would be appreciated with these processes).

This has been asked and answered over and over again.
It's a digital signature, which means that all of the binaries are signed using the same private key, which I'm sure Samsung has well locked down.
It's a sufficiently secure methodology that the only way we could sign custom binaries would be for someone at Samsung to leak the key.
Please don't suggest brute forcing it (it'd take several thousand years), removing it (won't work), copying it from one file to another, etc.
All of these have already been suggested by those unfamiliar with the technology being used.

I normally do research before I ask a question; this is an exception. I understand what ii is in general. I wouldn't suggest brute forcing. Several thousand years is most likely an understatement. The length of time exponentially increases for each added character. Removing it obviously won't work because then there is no signature to verify.
I was asking about the location because I thought it might be possible to port the key to a different ROM but I am unfamiliar with this technology.

[Q][RESOLVED] Browser app settings and sync contacts

Hi ,
Yesterday, I installed ubuntu touch in my nexus 4 and decided to use it as my daily rom.
So, i tried to modify some settings. Everything is working well, however i have two problems.
The first one : I failed to synchronized contacts with syncevolutions. It's working but it synchronise only one or few contacs in my .csv file. As a solution i used google contacts sync. But if somebody have (or had) the same problem it can be interesting to share the solution with evryvody.
The second one : I tried to change the browser app settings, but it didn't work. I used these two websites to help me :
"bazaar.launchpad.net/~phablet-team/webbrowser-app/trunk/view/head:/README#L71" and
"lists.launchpad.net/ubuntu-phone/msg10301.html" I removed the first part, because i'm not able to post outside links.
According to the first website, we can change the homepage and the searche engine, you can use the second website to understand how to do it, i followed the instructions, but it didn't work for me. So, if somebody want to try or already have the solution, it would be amazing.
Thanks.
Edit : Apparently It is now possible to change the search engine directly in the browser (18 June update)
Although it's about calendar sync, this might be helpful: http://forum.xda-developers.com/ubuntu-touch/help/calendar-app-doesnt-sync-t3054933
What's the content of your browser settings files? I have that working fine for me here.
Code:
[email protected]:~$ cat ~/.config/webbrowser-app/settings.conf
homepage=https://duckduckgo.com
searchengine=duck
allowOpenInBackgroundTab=true

The file is automatically generated on devel-proposed build 166 now. However, it's called webbrowser-app.conf there.
If you're on the stable channel, expect that your browser settings will break in the future. However, you'll simply have to apply your changes to the new file then.
Hello,
I decided to install ubuntu touch again after all the new things they made.
However, changing the browser is no more working for.
I just wanted to know if there was another way to do it or if it was only my fault ?
Moreover, is that possible to uninstall preinstalled scopes like 7digital, amazon, ebay ... ?
@Remy.L There is just one browser for Ubuntu (except one third party browser). You can switch tabs by swiping up from the bottom edge though.
No, uninstalling preinstalled scopes isn't possible using the GUI as long as they aren't in the store.

Now I get what you mean with "changing the browser". There should be a settings option in the browser itself now (install the update from this week if you haven't already). Give it a try.
If there is still something you want to change manually, check out the contents of the browser's data directory. I think they renamed the settings file.

Sorry, i did not mean browser but search engine (replace google by duckduckgo).
I did not managed to have it working in the new version.
Anyway, do not bother you, i'm not using ubuntu touch anymore because i'm do not like that path they are taking with this OS (you can not uninstall what you do not want).
As i prefer to use open source software, the best thing to do now is to use an AOSP rom (or maybe firefox OS)
Thanks a lot for all your answers and have a nice day
PS: Sorry for my English, i'm not totally fluent
Edit : Apparently with the new version it is possible to change and chose the search engine you want.:good:
However, I guess that it is still impossible to remove unwanted stock scopes (however, as it is possible to remove unwanted stock apps, it may be possible to do it soon)

You could try removing them with the terminal-app like this:
Code:
sudo click unregister --user=phablet com.ubuntu.badscope
That should actually work. Pretty much everything can be uninstalled, even though not easily.

You need to find out the right package name of the amazon scope (given that it is installed as a click package, of course; I was unable to find it using "click list").
The reason why you don't see the option to change the search engine is that the devel builds are really, really outdated. I think they are half a year old or something like that. Either install the stable channel or devel-proposed.
Ok, thank you for all your answers, it may help a lot of people
Unfortunatly I broker my Nexus 4 screen last week (I'm planning to repair it but not yet [in few month]) so i can not try this rom right now.
Once more, thanks again for your help and for your answers,

Hi nikwen,
I'm back on this forum because i repaired my nexus 4. Everything is now workinh, and the rom seems very nice.
However it is still impossible to uninstall unwanted scopes (like amazon) even with the terminal. (impossible to know the name of the scope).
I also tried this sudo dpkg --get-selections >liste but it does not list the scopes name.

Hi,
Yes, there's been a discussion about this on the ubuntu-phone mailing list recently. The reason why they can indeed not be uninstalled is that they are remote scopes with the code lying on a Canonical server and not on the device itself. I didn't follow the whole discussion, so if you are interested, check out the mailing list archive and you should be able to find the conversation within the first 5 pages.
Hi Nikwen,
So i checked your link and found what i needed
So yes, it is impossible to uninstall these scopes like you said, the only way is to keep it without using it.
But the thing i was thinking about is : If you do not use these scopes does it still get informations from you (in background) ? (because and do not want it to use my data continuously)
Sorry for all these questions
Have a nice day,
Remy
@Remy.L No, they won't be giving any information away. Scopes only run when they are in the foreground and even if they are, they are confined by a software called "apparmor", which means that they cannot access any data besides that which you enter into the search box. They don't have access to any of your private stuff.

Some Hacking in Yoga Book

Hi folks.
I'm an Android firmware developer (you can see my posts here in xda) that got a yoga book yesterday. For me it works at it should (by now) but my hacker soul speak to me and said: "at least take a look to see what you can get from this device". I don't have many time, so I can't spend time doing roms or fixing things by myself, but I can share with you some info I get and help you with my knowledge if someone is interested in "play" with this device.
First of all, I'm not responsable of anything that you can break following these steps. Almost all of them are tested and with some common sense you will not break anything, and if you break anything I will try to help you to fix it (if you are polite), but this is a work in progress and hacking and the possibility of brick the device is always there.
I only have the Android version without LTE, so I only tested in my Book.
So, here we go:
1) Secret codes:
I get this codes decompiling EngineeringCode.apk with apktool. Be carefull with them:
####0000# - Display version info
####7599# - Display hardware info
####8375# - Display baseband info
####1111# - Factory test
####2222# - Display SN
####7777# - Factory Reset???
####5993# - Display internal frameWork version
####7642# - Cut the power off to reload the PMIC - This command shutdowns the device. Just press the power button to reboot.
####5236# - Display LCD name
####2834# - ES close test
####8899# - open the ums mode default for debug
####3333# - offline log
####3334# - offline modem log
####9527# - Mediaplayer setting
####78646# - RunIn test
####6020# - switch country code
####59930# - Display current country code
####8746# - Enter engineering mode
####4227# - Enter engineer test
####357# - DLP_TEST
To use these codes, open the contacts app, press the search button and enter the code in the search bar.
2) OTA Images
You can get OTA images directly from lenovo servers. Just open your browser and paste this url:
http://fus.lenovomm.com/firmware/3....WW06_BP_ROW&action=querynewfirmware&locale=en
Change device model if needed (LenovoYB1-X90F or LenovoYB1-X90L)
Change curfirmwarever to a valid OLD firmware, this way you will get the next one in age.
Change locale if needed.
With this url you will get a download url at the end of the result page. In this case: http://tabdl.ota.lenovomm.com/dls/v...S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
These images are not full ota images, they are diff versions. This means that we can't use them to mod the image, or recover a bricked device, but this is a first step
3) Custom images
We don't have real sources to build a custom image (the lenovo's open source files are useless), but this doesn't mean that we couldn't modify stock images to take out useless apks or get better performance.
We can get this using an Android Kitchen and a full update image for the device.
As Android kitchen you can use SuperR kitchen (https://forum.xda-developers.com/ap...chen-superr-s-kitchen-v1-1-50-v2-1-6-t3597434)
As full image, I only tested the one here (https://easy-firmware.com/index.php?a=browse&b=category&id=19521) because I can't download any newer one.
I tested uncompressing it, deodexing the apks and doing a new image. But I don't test it in the device because I need to install twrp to flash the new image and I don't have time to test. But this should work, I did it many times so if someone is interested I can give steps to do it and support for testing.
If someone can get the latest full images, send then to me and maybe I can get some time to do some tests.
PD: Probably we could use this as a base to get LineageOS 14.1 working: https://github.com/latte-dev/android_device_xiaomi_latte/tree/cm-14.1
So, if you are interested in some hacking with the Yoga Book, contact me and we could team to get the most of this device.

I have the full "YB1-X90F_USR_S000196_1611040312_WW06_BP_ROW" I can upload somewhere if anyone can suggest a good site to do so without signing up? The file is about 2.5gb
It will be great if we could get the latest version, because maybe these older versions have older files that we have updated in our tablets.
Mixing files could give unknown problems
The current TWRP is based on the new Yoga Tab 3
I am starting to think they do not do full roms for this in the same way they do for a lot of their other devices.
We know the otas are available from tabdl.ota.lenovomm.com/dls/v6/ and are named according to the 2 builds that it bridges. As easy-firmware had the december full rom under the file name B1-X90F_USR_S000196_1611040312_WW06_BP_ROW-flashfiles.zip I had hoped that I could work out the file path to pull it down.
There were some interesting ideas here, https://forum.xda-developers.com/android/help/how-download-stock-roms-lenovos-ota-t3109507 but it seems there is a difference between phonedl.ota and tabdl.ota
Queries to full roms that work for phones, don't seem to work for the yoga book.
Anyone with more web knowledge able to pick this up? I am not sure the files are there but I feel they should be.
Good luck
Update: the downloads seem to be hosted via CloudFront. An Amazon service, but I can not find out a way of listing the available files. The latest full rom would be
http://tabdl.ota.lenovomm.com/dls/v6/YB1-X90F_USR_S000426_1705080316_WW06_BP_ROW_WC80C2A0F2.zip
But the Last 8 chars are random and we do not know what they are.
So we have two hopes. First work out the right query to the link from fus.lenovomm.com or two find a way of listing files available in tabdl.ota.lenovomm.com/dls/v6
Not sure I have got much further but ill keep trying when I can.
Hey, I should mention that I have some files that you may find helpful; I got them from the easy firmware website. They're all the .img files for each partition in Android (ie. boot.img, cache.img, config.img, factory.img, recovery.img, system.img) as well as: biosupdate.fv, bootloader, firmware.bin and gpt.bin. However, these of course aren't in the normal "flashable .zip ROM" format. So unless you know how to take apart these .img files they aren't very useful. If you need any more help or have any other questions about how far we've come on our own, feel free to ask. danjac also has great knowledge of our efforts.
Yes, I know how to use them, unpack, modify, etc. But what I want is the latest version, no a old version (I hav these files too). If you have them I can do some changes, debloat, etc.
Anyway, I see little interest in custom roms in this forum ( probably because it's not a device with a lot of users or the users are not the techy kind), so I prefer to help others with info than do a custom rom that only 2 or 3 people will use. Doing custom roms is a time hungry task and probably it doesnt worth the effort. Anyway this device is not full of bloatware like samsung ones, so it useable as it is.
As I said in my first post if anyone is interested I can give some hints and support to modify the full image (but only the latest one).
It's so sad that there are only a few interested owners of this tab - it's such a nice device but i fear the day lenovo decides to end their support for it. There will be no custom roms to switch to and keep the device alive - it will be a soon to be bit of old tech garbage BTW. I still use my Asus Transformer Prime because of the nice community
@NiffStipples I fully agree. This device is so powerful and its a suprise that it is invisible to the "market". In my humple opinion the normal ROMs aren't that bad besides missing updates but I would love to see all the power served through a custom rom. unfortunately programming is not my business

Interesting - is Crossover good (and does it require factory reset)?
Hi, It works well with some things and not others. Often the why and where are not obvious. It is basically "wine" the layer that allows some windows apps to run on a linux install. Tweeked to work with android. Just an install to put crossover on. Then another install (Within crossover), to put you app on crossover. If it doesn't work out of the box, there windows libraries you can switch out and dependencies you can install. (Eg: directx , .net) Even if your not technical. I would say get on the beta program and give it a try.
Hi! what do you mean by "lenovo's open source files are useless"? do you refer to this packet on lenovo's suppport site? download.lenovo.com/consumer/open_source_code/lenovo_yb1_x90f_l_osc_201608.zip
I've entered the Android YogaBook's BIOS and noticed that VT-X is enabled by default! With Limbo x86 we could get a fully working virtualized Windows or Linux, if it wasn't for... KVM. It seems like it's not enabled in Lenovo's default kernel. Could we get to recompile the kernel with this option on? i'm not a big android/ROM expert but i surfed the open_source_code folder from Lenovo and it seemed, to me, that we could rebuild the Kernel at least.
This could really change things!

How did you enter the bios? Can you boot from usb?
anyone managed to use swiftkey keyboard?

Exchange platform-signature in custom ROM

Hi there -
short prologue: I am working on my bachelor thesis and must develop a service that keeps a record of how often a user actively uses the application permission settings of Android 6 and above. The main goal is to have a custom ROM which can be deployed on several phones to conduct a survey.
I identified the file where these settings are stored:
Code:
/system/users/0/runtime-permissions.xml
I want to set up a service running a FileObserver to keep track of the changes in this file. The file is not accessible by normal applications (permission -rw-------) but the service has to run without superuser.
So I want to sign my application with the platform key to obtain system permissions. I am totally clear on the purpose of this security concept and I know that I cannot get the original key. The resulting ROM is not going to be public and is used only in a controlled group for research purposes.
My question is how to exchange the signature/key with what the system applications of my actual ROM are signed. So that I sign my own apk with the same key so it has the special permission. I found the answer to this exact question on stackoverflow but it is quite old and I did not succeed with this explanation.
Do you know if there is another, more current approach?
Thanks in advance!
Device is a Xiaomi Redmi 4X running stock MIUI 9 (Android 7.1.2)
Just have the app built as part of the rom. This will make sure they both have the same signature.

What do you mean by "built as part of the rom"? I cannot build the rom from aosp because the device should run the original MIUI firmware. I used SuperR's Kitchen to modify the rom. Is this not suitable?
That will not work no. Maybe you could try using their patch rom setup. As very little is done with miui here, you mugjt be better off asking in n their forums.

Can you explain, why this wont work? I supposed I just have to exchange all the signed apk files. When I re-sign them with apksigner then they also obtain the self-signed certificate containing the public key. So why is this not enough? Is there another instance in the OS which checks the app signature on boot?
The entire system partition uses the same signature. So I guess you could go through and recompile everything with the new key but I doubt it would work. Many oem system apps won't work without their oem signature.
Like I said. You maybe better off asking over in the miui forums as very little is done here for it.
