Cf on October 2015. Upd 05012016. Mainly for me.


1) Intro:

After the OTA update on 20151023, I wasn’t able to install Xposed framework.

Since Yesterday, I am reworking on it.

Again, thanks to XDA-developers (@rovo89 and all), androidhilfe.de people for the tips… 2) What’s going on:

– Install XposedInstaller_3.0_alpha4.apk
– Download xposed-v79-sdk22-arm64.zip (I tried to use old xposed-v74xx, so do not used it).
– Previous xposed-uninstaller-20150831-arm64.zip, is still OK 😉
– Install Xprivacy from playstore
– Move /system/media/bootanimation.zip and shutanimation.zip to external sdcard. This is to give space for Xposed,

2-1) Xposed install:

– Boot to twrp (russian one, with mouse usb)
– Install xposed-v79-sdk22-arm64.zip. It’s gone thru 🙂
– Dalvik & cache empty
– Reboot
– Wait up to 10 mns (several reboot to optimze apps)
– Once reboot, run install Xposed, run Xprivacy to download latest version.

This is a cookbook article, written for me mainly.

1) Intro:

On my chinese smartphone SISWOO C55, 5.1, Google play warned there is an update for SuperSU (Chainfire), 2016.02 . I tried to update SuperSU binaries: failed. Soft brick.

Googling XDADEV site for more informations. Thanks to the members feedback, I was able to do it. There are different ways to do it.

Describing here is one of them.

2) SuperSU update > 2.65 :

I choose to try out the beta version 2.67, for several my android smartphones which are rooted, aka Oukitel U8, Mlais MX base, Siwoo C55 …

Keep in mind: it suffices to get a higher version than the stable one as proposed by Google play store.

Download 2.67 beta (zip) from XDADEVS site.

2-a) Boot to custom recovery TWRP or CWM;

2-b) Install 2.67 beta zip

2-c) Reboot and check with checkroot app.-> OK

2-d) On one smarphone, there isn’t the SuperSU app icon.

Check with ES xplorer /system/app/SuperSU folder. Under common folder, there is SuperSU.apk , click on it and it shows no information (void).

Extract the BETA-2.6.7xxx.zip, double click on SuperSU.apk to install (with unknown source on). Now, the SuperSU app shows up (thanks to a member in XDADEVS forum.


It’s nice to have independant devs and sharers. Thanks to them. Donate if you can.

1) Intro:

This article is written mainly for me (to remember).

I have a LG g2 mini LTE D620FR, 5.0.2, single sim, 1G/8G, bought at a bargain price.

I bought this smartphone mainly for its Cyanogenmod supports, and the promise to get updated to Marshmallow. And fix current vulnerabilities ….

– I am amazed, that this little phone is quite good and 1st released in 2013 … Got 5.0.2 update.

– Today, I jump to Cyanogenmod 13, after a long time of musing … Will it go thru ???

– Yes, I did manage to switch to CM13, easier than I thought. Thanks to XDA-developers, phonandroid, youtube, etc …, to people willing to share their experiences.

2) Steps:

1st of all, charge the smarphone battery …

– Rooting, with kingo root (yes I know that …);
– Bootloader unlocking , for D620FR=D620R; take the right aboot; Use android terminal, su, dd if= …. of=…
– Install Flashify app; run it; backup current recovery.img and kernel:
– Download twrp 2.8.6, CM13, nighly built, Gapps … (Thanks to @Azanay on Youtube …).
– Use Flashify to flash twrp;
– Use Flashify to go to recovery mode (teamwin) or twrp;
– Use TWRP to backup current recovery, system, data;
– Use TWRP to reset to factory; install CM13, gapps (-600). clear Dalvick, cache, Reboot.
– After reboot, takes some minutes to improve app performance (here I have 14).
– Log on CM13, my sim card detected, configuration, google restore id …

3) Conclusions:

– At last I got Marshmallow via Cyanogenmod CM13; I can see the source …
– The current stagefright vulnerabilities are closed in CM13; in version 5.0.2, cve-2015-6602 is still there.

Dawn of life ?

Casual monolog.

After a long time of silence, i.e , not writing anything on my pretty life, there I am.

I am pretty sure, there are some people who are very interested on what I am doing, for reasons I am just kinda guessing. I don’t think I am paranoid (or just mildly), because I was collecting indices. Remember that I was trained and praticed as a technical engineer in several fields. And I am still been trained …

– I was already retired in FR (the retirement pension was a hard “parcours de combattan. The administration was reluctant to open the case: paper works, missing secret code in my security number … But I never let down, and I got it. Combative and patience.

– This year, 2016, is a milestone: I am retired from CH.

Before that, my wife got her retirement, without any problem, by just writing a simple letter, 6 months before the anniversary date. Last year, I got a letter form administration, with my name only. The administration asked me to provide all my revenue, and asked to justify my living (?). I called the guy, he told me, that the administration wants to know my revenue and not my wife (are we married or not?). I was asked gently to pay for the back retirement tax for me and my wife.
– Some months later, it was my turn to make my retirement claim for CH. In return, tha administration asked me again all my perceived revenue. only me, and the guy told me there was something wrong between our income tax and my retirement declaration (?). Gee, Income tax administration, retirement administration, secret services are collaborating !! Was I among the happy few in this regard ? Gee, I felt important, for a short time.

– My question(s) are, why my wife (she is swiss national by birth) has nothing to do with me ? and I am the only debtor ?

– Why the heck they were and still doing, when I return to CH in 1984 ?

– What was happening after 1990 ? the years I worked for Geneva administration as computer engineer ? Because, since then, everything in my family life went amok!

– Dudring 2004, I got cancer, and saved by a dearly nice Dr Bur…er, operated by his chirurgian friend Dr G…. . Thanks to them and my private doctors, Dr GA.. and SM… The later helped me dearly for than 10 years. Still, the public hospital, by that time was very hard with me. (my feelings).

– Dudes, now I narrow up to for regions: FR,CH,US,VN . The are quadruple cross in the 4 corners. To what end ? Who am I, to be “so” damned important to silence off ?

– In April of 2016, I got pneumonia and hospitalized urgently. No bacteria detected. Apart from my wife, my daughter (who has called medics, ambulance …), my son, my son-in law and his family in Morocco , who cared ? It was my little grandson I owe somehow for the quick intervention. Thanks to them all. And to God.

– Life is hard for all. I was, I am and I will be alone to fight sorrows, threats, for me and family.

– I don’t fear death. I don’t know if there is a Eden or Hell. I am, I say, I act as best as I could, no needless harm . If I have to fight, I will.

– The other day, my grandson ask me, what are the most importants things for me in my life ? : Never turn my heels, show my back, look at the threats.

– I know there are people who don’t like me at all, even those I never met . Why should I care, act to please them ? Pay them to be nice to me ? Why should I be always the one to backoff, to beg them, to salute them the first ? Are they better than me ? People are wary, specially females, am I looking so threatening ? I steal no one, bad mouthing no one. snear at no one. Yeah, may be I should be … That’s why there are so many victims …

– It’s time to say, give back to Caesar his due, and to me my due. I know what I did to improve even invent things even to come. I have been denied. You can steal, but someone knows.


Why play with a guitar ?

popularity : 1%

For my 15th anniversary, my mother offeredme my first guitar, a starter Sunburned one, with a music notebook. I bought a small book to learn how to play basic notes, chords frettings and songs. I wasn’t good for learning solfege.

When sojourning in the States, I bought a LP disks, with booklet, The Ventures. Of course, I wasn’t able to play a whole song, too complicated.

So, most of the times, I listened The Shadows, The Ventures and some others I don’t remember.

I kept the guitar, this disks, books for most than 20 years. Bringing them with me where ever I went to live with my family, France, Switzerland.

Most of my oldies are gone, too long a story to tell. I miss them.

My first electical kit guitar was in 2004, dirty cheap one. A starter kit. The sound was awful.

I have had no time to play and alone.

In France, circa 1980, we lived at the outsirts of PARIS. There were quite a lot of indochinese refugees, mostly chinese, cambodgians, laotians. The Vietnameses snobbed us most of the time, may be I was not fluent in Viet, and my wife is European, The people in town were those refugees, there friendly and we exchanged in FRENCH. A small group of cambodgians and loatians invite me to play with them. but I was unable to play anything they knew of. 🙁

I knew then that I won’t be able to integrate into any group. I don’t know how to play …


Playing like shit

I have to write something for september 2016.

I just see there are almost 2000 messages on the site ! To be true, I don’t dare to look at them !

What to say ? I am sad by looking/hearing at world affairs. So, I prefer to look and learn at scientific, technical and arts topics. Yes, I do learn …

I try to be positive, but I have to cope with hatred. I still don’t understand why ! Even if I haven’t done anything bad to them!

On twitter, there are hatred groups who ticked “like” my tweets about Asian killed and being insulted/threated in Paris. I have had reported my own experiences, here.

How do I feel ? Yes, I am french and swiss citizen by consent. So what’s the problem ? I am vietnamese as well, so what’s the problem ? Supremacists ? Come on, stupidity !! Just look at yourself…

Not to say that Asians do insult among themselves !

I always say that war is : one nation against another nation. If people are insulted, threated, killed by their fellow citizens, then it is: suicde (of the nation).

By extension, human being against human being is : suicide (of the human genus).

Hey supremacists, if there weren’’t others, then how would you called yourselves ? who will work for you ? The doom would lurk, because at the end there must be one left (aka citation of a movie)! EOF, morons.. History has shown that this kind of people were just parasites (using slaves). So be careful, just one slave offspring who takes conscience could blowup the whole system one is relied on (grain de sable).

Just show and fight for my dignity. Yes, I do !

1) Intro:

This is for my own usage mainly.

I was desperate with oem android vulnerabilities, since last year with stagefright and all.

I am buying entry and mid level OEM smarphones.

I am looking for alternative ROMs and mostly root them.

My last purchase is Motorola E LTE (2nd) XT1524 (global). Which I updated to Marshmallow 6.0. But it has the stage right vulnerabilities for 2016 !!

But why this model ? Because it has surnia cyanogenmod supported, inexpensive and good little phone ! Thank you cynogenmod surnia guy(s), I will donate to you 🙂

2) Installing cm13 :


– unlock bootloader. It was my 1st unlocking ! Took me time to go thru.
– install twrp, by squid2. Thanks.
– install pico gapps: ko. I missed something.
– install F-DROID client. Why not ? https://f-droid.org
– To add apk from Google playstore I follow http://techapple.net/2014/09/3-webs…

PNG – 72.7 kb PNG – 62.2 kb

PNG – 338.4 kb PNG – 98.6 kb

3) Conclusion . Temporary:

– I will take time to test this smartphone setup. I’t’s not vulnerable according to Zimperium app.
– Due to my failure to install gapps thru gapps, I use F-Droid and sudeload apk from Google play store.

– Later on, maybe I will return to gapps, but with another smartphone +cheap if course). For the time being , I am pleased using this setup. Thanks to the good guys and gals from XDA, cyanogenmod, f- droid and open sources programmers.

Android Stagefright & other vulnerabilities – temporary solutions.Upd 16112015,26112015,25122015,26122015,20042016 (p8 solved)

1) Intro:

This is written mainly for me.

The Oukitel U8 with OTA update V15 20151010, left cve-6602 stagefright unsolved.

During 2016, I saw that the unknown source is switched on by itself. On the web people report that this and two malwares recents and beauty apk were the culprits (20151010).

A rom was released on needrom.com, 20151227, with no changelogs, I hesitated till yesterday. Some people report this version solved the malware problems. But no mention of stagefright.

I decide to give it a try.

2) Results:

Windows 7 (not anymore supported)

From needrom.com , http://www.needrom.com/download/ouk…, download the 3 files for flashing:

Official ROM V17.0_20151227 Last Update Android v5.1 (Rom name: OUKITEL_UniverseTap_FZ_V17.0_20151227)

– Install the driver.
– Extract SP
– Extract the rom zip

— Switch off Oukitel U8
– -Launch the SP program
— -Scattwer file
— – Choose Upgrade
— – Click on download
— – branch USB cable ….. check with windows panel peripheral manager for COM&LP

If not starting download, unplg and plug again the USB.

It will take some minutes to download and upgrade. When successful a popup screen will show up with a green ckeck symbol.

3) Conclusion:

– Unplug USB
– Power on
– Ok, the Oukitel U8 seems to be clean, reinstall the minimum. Check with Zimprium app: No more stagefright vulnerabilties (2015-2016), with android version 5.1 .
– No more Unknown-source switch to on.
– Coss my fingers …

– Thanks to people who are reporting their troubles and solutions on the web.

Oukitel U8 – 2015 stagefright resolved, malwares.
