Already done. Beware, there are some serious typos in the code. Quote:
And making a KUAL menu button to launch it, not exactly a 'clean' way to do it. He did use NiLuJe's bridge code to make the Android install "update safe". Quote:
The person had been selling Android conversion services since they first showed up here about a year ago. I don't think there is any leak involved with the NXP (f.k.a: Freescale, f.k.a: Motorola) tools - they have had an Android example up for years. But I thought that their example used RedBoot, not U-Boot. I could be mis-remembering that. Yeah, that version is just about when Android adopted SELinux in full enforcing mode. IIRC it was somewhere in the 4.x series. And if a person is planning to deal with that, they might as well start with a base of AOSP version 8.x = = = = Personally, I want to wait and see if Amazon announces an Android build for the i.MX6 Kindles. There must be some reason that ADB can be found (erased) on some of them. Although I will admit that I have spoken (written) with a few people privately about what to do if that is still what is being done - selling a "closed source" version for profit of the open source Android project. And (properly) releasing a free version seems to be the best and quickest way to put an end to that. Also, it appears that person is using Google's Android branding in ways not allowed by their branding usage publications. Getting the Chinese government to pay attention to a few pissed off programmers is not likely to happen, but they will listen to Google - who is a major contractor of their GFC (Great Firewall of China).

I have found where the registration code is being checked.
inside the zip http://182.254.232.41/firmtest/andro...dle.171102.zip there is a file named esystem.bin. (It should be similar for the other devices and versions) This file is really an ext4 filesystem (you can check with "file" command). Mount it: mkdir droid mount -o loop -t ext4 esystem.bin droid Now look inside: cd droid ls you see the android filesystem (app/priv-app/etc) I used apktool to decompile all apks, and found an interesting one JSONClient.apk. It has code to force itself to be the default launcher, and lock out all other apps. It also checks the device serial number, etc. So it is almost certainly the registration check. I used a java decompiler to read the code and found that it uses a jni library "libjnidemo.so" (LOL) to create some kind of hash of the serial number, upload it to kdroid.net, and check the result. Rather than try to crack it I think that you could just delete that apk and then install the modified image. |

Long time no see.
I find it seems to have made some progress. I think I need to read it carefully. |

I finally have time to move, but I found that I do not know how to delete the apk, because I simply will not extract the bin file.
I think I'm a fool ... I first learned how to open the bin file ('⌒`.) |

Android of kindle
I have found recently that one special version of e-ink kindle has a firmware seems like using FireOS with u-boot
The product: https://www.amazon.cn/dp/B01I235KH4/ref=fs_kindlemigu The firmware: https://s3.amazonaws.com/firmwaredow...gu_5.7.2.1.bin The source code: https://s3.amazonaws.com/firmwaredow...171121.tar.bz2 I think the person's software is based on this firmware. |

Nice find. Last I looks at this it was reported that it was a re branded kindle touch, but this new firmware is a great find. I have confirmed from extracting those it looks like fire OS. Code:

https://forum.xda-developers.com/and...es-to-t2978952 This is definitely android built for kindle by amazon. I installed one of the APK, and I dont have all the depencies, but it did load up, it wants me to log into some page that is in chinese, I assume the partner amazon went with there.
