Modification For default.prop (“from boot”) / build.prop (“from system”)

Done for cm_golden-userdebug 7.1.2 NJH47F db0312e049 release-keys/RR-N-v5.8.4-20170821-golden/rr7.1_golden.nova.20170822.zipNougat 7.1.2 (Resurrection Remix) 20170822, for Samsung Galaxy S3-Mini NFC (I8190N).
The base of the partition-structure is from I8190NXXAMI1_I8190NILOAMJ2_HOME.

It will disable the Security-Enhanced Linux (SELinux)🔗︎ and newly Android 7.0 added dalvik's ART Just-In-Time (JIT)🔗︎, the SELinux will be set to permissive settings, just in-case it will be enabled in the future. The modification will allow mtp and adb access from boot and recovery, so you could access your phone at that stage too, it will resolve some WiFi and cast problems and will allow ADB access without annoying popups (default allowed), knox is disabled too but it won’t do much on the custom ROM (unless you’ll be manually download KNOX to access Samsung-pay, which in this case it could be useful to keep it anyway).

Reverse Engineer And Modify D-Link Binary Firmware File

Some time ago I’ve published an article(post?) about blocking ads using the router,
while it works just fine for non-html files, such as scripts, images and such,
it isn’t so great solution for blocking iframes that shows HTML content,

when the (original firmware) D-Link router software identify a forbidden domain,
it sends out a series of responses, ending with a html page (HTML 1.0 302 redirect -> 200 response page),

while for <script> elements it works perfectly, since it renders an invalid script,
– blocked domain, which shows ads, for example in an iframe in the page (such as eBay),
will still block the original content, but will show an iframe, well… filled with the D-Link’s blocked page msg:

Android System APK Path

Does not required root access, pulling is a great way of using some “vendor only” applications, for me it was a very well-designed Hebrew-Date calendar, only available in native Samsung-Galaxy ROMS for some vendors.

Other than that it is a slow (one by one), but sure way of file backup, from “root location” that is available on readonly basis.

alternative options maybe using a file-manager such as “X-Plore”, and compressing the entire folder tree of the desire “root location”, placing the zip in a readable location on the SdCard, the entire process might take a while but the download process will be much faster due to one-big-file-handling instead of one-by-one fetching which requires a lot of “connection” overhead..

Reverse Understanding – Service

appspot is a sandbox/playground (whatevvvvveeeerrrr….) for apps…served by Google Frontend servers

breaking the logic without any whitepapers was quite easy…

I was proxy’ing my phone’s addresses, through my PC’s FIDDLER, this is a monthly routine,
since I need to keep up with all the junk push through publishers, through their new updated applications,
after I’m maintaining a list of all new PING, TRACKING, STATISTICS, ADVERTISEMENTS and plain old UNNEEDED JUNK,
I’m adding it to my sub-website

this time I’ve noticed something cool: using the host-name: with a simple mimetype of text/html and short GET request:

request was made by some open source application named DroidFu:

User-Agent: Android/DroidFu
Connection: close
Connection: close

response was just an ip..

HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8
Date: Thu, 11 Dec 2014 07:56:31 GMT
Server: Google Frontend
Cache-Control: private
Alternate-Protocol: 80:quic,p=0.02
Connection: close

looks like an escaped-base64 argument, I’ve thought..
using my good old base64 enc/dec here

it was double enc/ in base64


(first base64 decode)->
(second base64 decode)->


so this one was just a simple reverse hostname ( to IP (…
double base64 looks kind’a overkill, fishy?? don’know..

from my experience it just may be a plain Anti-Fraud (Anti Man-In-The-Middle, Proxy/DNS Poisoning, etc…),
this way the IP is resolved through an external-server (a.k.a “safe place”), other then a risked machine (self Android device),

simple but effective….
