Jiayu S3 PIN Locked by Kinguser app

First of all, I may be posting this in the wrong section. But I desperately need your help on this.
I got a Jiayu S3, and couldn't not try to flash a custom rom on it, so I tried with "Pure AOSP V1 TF".
All went well, untill i found this app which was included with the rom, "Kinguser" (should be Superuser, i believe), which game me the option to toggle root.
At first and only time I opened this Kinguser app, option root was active. I did deactivate it, and reactivated immediately after.
As soon as i reactivated root, the privacy pin screen showed up.
I didn't set any PIN on my phone, so at first i thought it could be something like 1111 or 0000. Tried 5 times and it made me wait 30 seconds. Then tried another 3-4 times.
Here began the real mess: "forgot pin" (or psw) didn't show up, but at the time i didn't even know about that recovery option.
I didn't know what to do, so I just thought that a factory reset would certainly solve the problem, how couldn't it? Well, wiped everything, but PIN lock screen didn't go away.
So, wiping everything, I also deleted my gmail account from the phone, and I lost the possibility to lock phone and give it a new password (Android Device Manager). Too bad at the time I didn't know about this recovery option as well...
Now I'm out of ideas. I think I've tried every method I could find with a search of "Smartphone PIN locked". Tried with resets, plugins, deleting files with adb..
How do I unlock my phone?
little update: after a factory reset, for 2-3 seconds, it shows the default initial screen, but it doesn't last more that and i just can't do anything.
Now i managed to bring back the stock rom, but with that i lost the twrp recovery, and i can't find a way to make pc recognize the phone to reflash it.
It seems it's going worse instead of better...

I had just bought this Jiayu S3 and planned to bring it on holidays on wednesday, but i'm starting to think i won't be able to fix it before then

Did you have any resolution to this problem. I am currently sitting in the exact same boat. Did the factory reset, pass code screen still there, I didn't set a pass code. Basically hands tied, can't update firmware, guessing i'll have to get a new phone, but hoping maybe you found a miracle cure! ha! - Thanks for any guidance. - Arden (Seattle, WA)

Just flash another rom (stock/original) and start over.

How have you done that?
Can you help please?
I tried factory reset (volume plus+ power button), hard reset (volume- plus power button), update, and nothing works; I also went to two different specialized stores and they failed to find a way to reinstall the original Android version or a recent one.
Comparing the files with the factory version installed in the phone, the phone report identified three changes:
- a new file: /system/priv-app/7mK0T6e8Z5.apk
- the lost of a file: /system/app/com.android.fallen.apk
- and a modified file: /system/bin/debuggerd

To flash firmware you can use SP Flash Tool on a windows or linux computer (not sure about macosx). You have to decide which firmware you want (which one do you have now?). The 'official' firmwares can be found on needrom. SP Flash Tool can be found there as well. There are 2 popular LP firmwares built by Jiayu resellers in Europe (Xtreme from Spain and Jiayu.de from Germany). Guides on how to flash are often present at the place where you find the firmware.

Thank you!
I found "Xtreme from Spain":
needrom.com/download/rom-xtreme-rom-tf/
I found the "SP Flash Tool":
needrom.com/download/sp-flash-tool-v5-1424-00/
but it is for Linux... can you send me the link of the windows version?
And I could not found the "Jiayu.de from Germany": can you send the link?
Also, can you recommend some good manual for dummies?
Thanks again for your patient and help!

latest sp flash tools is 5.1532
search needrom with "5.1532" will leed you to the download page
no link allowed here, so ...
for beta 10 from jiyau.de, search google with "jiyau.de Lollipop 5.1.1 - Beta 10 (14.10.2015)".
it will leeds you to the rom.
Good hunting

I would like to add: if you come from KK and go to LP, you must use firmware upgrade to update/adjust internal SD partition layout. Good Luck! if you succeed, and are happy with firmware, consider voting @ http://forum.xda-developers.com/android/general/firmware-jiayu-s3-t3212184 (almost 100 votes)

First, thank you for your great help!
With your suggestions, I managed to install Lolipop in my Jiayu S3S (upgraded from Kit Kat) - Xtreme ROM TF (JiayuS3-5.1Extreme1.1SP.zip).
However the problem remain... the phone still is asking for a PIN (that I never had put there, in first place)...
What should I do now?

you could try factory reset and are you sure its the phone asking for pin and not the sim card

TWRP Reinstall Firmware after deleting

Hey dudes,
i bought a second hand huawei p8 lite ALE-L21. Because of old stuff from the previous owner i wanted to reset the device but instead of only deleting the personal data i wiped everything.
End of the story is:
Booting to team win is possible, so i thing it should be possible to install a new firmware.
Problem: I don't know, what firmware i should use and on top how to install it. (yes, i was looking a lot for tutorials, but last device where i used a cfw was my galaxy s2)
Bought at vodafone germany with branding and single sim.
Best option would be a stock android 6
Looking forward for your help and just ask if you need further information
regards James

hi,you ca try here http://forum.xda-developers.com/p8lite/development/custom-rom-emui-4-0-android-6-0-ale-t3385630

Or flash via fastboot: recovery,cust,boot and sytem from b049(single-sim) or b052(dual sim) from update.app using huawei extractor
Then flash via local update b170/b171 then b564/b565.
This option is if you want a stock clean rom.

Hello,
had you already took a look at @k1ll3r8e's thread ?
He made a toolkit that can do what you need.
Best regards
Edit:
Dude you can do that also without the toolkit.
You only need the right oeminfo dual sim
and the correct rom.
Feel free to ask...

hello dadditz,
thank you for your reply! Of course i read a lot here and other sites, and also found the P9 toolkit! But my problem was/is, that i cant "upgrade" to VNS-L21C432B160 because i already was on VNS-L21C432B503 ... so i tried different things, but it did not work. Always the menue "Dual sim configuration" was not in the settings menue... and the image felt little bit "laggy"...
BUT
i was giving it another try - i downgraded from Nougat to MM with this ... tutorial and repeated the steps listed in the P9 lite toolkit... and now i have the Dual-Sim menue in the settings dialogue... and it is working
Because its not "enough" i wanted to return to Nougat - until now with no success... so am i now stuck on VNS-L21C432B160 ?
I tried some images from 380/370/336 but the huawei recovery always stops on 5% and denies the update - how can i upgrade again?
kind regards

Hey,
I think you could save yourself from going back
at MM, but, the omelette is made now ...
Have you already done a factory reset + wipe cache in stock recovery ?
Tell me a little bit when you reboot the device
does any warning text come out ? if yes, what color ?

Well, when i was on Nougat, i was not able to see the "Dual Sim Settings" in the settings menue - i tried 20 times
i think... when i went "back" to MM the menue was immediately there...
I did the factory reset and wiped cache in stock recovery menue.
Booting up my device seems all fine - bootloader is relocked, no warnings or anything...
HiSuite told me that my device "has the latest developer version" and no upgrade would be available...
I tried to flash the firmware with TWRP - without success...; when i try dload the phone stuck on 5%... i also
tried the "-PV" versions - without any luck...
So i really have no idea left how to upgrade from this version?!

Use Firmware Finder to force the upgrade, download it from the store.
VPN method worked fine for me (i was on android 7).
Inside the app all the info, anymore
a thread is present here on XDA.
Give it a try...
You're on B160, go for B370 PV version, check compatibility otherwise choose for full ota one.
Good luck

did you encrypt the internal storage with the fstab.hi6250b.zip then format Data partition....reboot to recovery...now wipe Cache, Dalvik, Data, intern Storage and System...reboot to recovery again. Now you can flash a custom Rom

Hi,
To be honest I fixed the phone. I think android orzo now is enough.
But I will do your preposition surely many thanks
