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

I can't install any ROM and i have no backup (or OS)

Hey! First thing you need to know: i'm stupid af
So yesterday i tried to root my Huawei P9 Lite VNS L31, and everything was doing great: bootloader unlocked and everything.
Because the root didn't seem to work on EMUI, i tried to install another ROM (i'm stupid) with TWRP: so I wipe cache, system and data in order to do it good, i flash the ROM but now when i tried to reboot it didn't boot.
So i figured that i was trying to install a MM Rom on an Nougat (at least it was) device. I then tried another ROM and i didn't work either. After hours of trying to make it work, now it boots on Huawei eRecovery, but i already tried to use it since i made no backup (i'm an idiot), and it seems to fail every time? idk it only show a big red ! mark
Right now i'm still looking for a fix but i would be soooooooooooooooooooo freaking relieved if someone could help me please :crying:
(i'm an idiot)

I DID IT!!!!
So i followed a tutorial made by the website androidmtk (i can't link it it's my first post), and is used the official stock firmware for my phone which you can find on cusumer huawei dot com
DONT FORGET TO BACKUP!!!!!!!!!!!!!!

Killed P9 Lite instead of getting back to live, maybe there is a last chance?

Hello, short Story before. I got a full Hand of non working mobile phones because being full of a hell of viruses.
5pcs. younger ones.
2 Huaweis and 3 Samsungs.
Well so far 4 PCs. are saved.
Getting into the phone wasn´t possible anymore. Data not important so I resettet over the Buttons to original Status. -> Worked fine.
But one Piece which is a Huawei P9 Lite guess it is a single sim? was the button method not possible cause it wanted a Software update and Installation of WLAN failed (EMUI)
Getting into the phone for any informations was also not possible because of all the viruses and not working right ahead anymore.
Well ok -> will use High Suite for stock Firmware -> this mobile phone is not supported and also couldn´t activate MTP as I am not in the phone. So far.
Next Idea -> ok. will take the C900B300 and go back to Marshmallow. From original HUAWEI site.
Took the European Version in German. Did it over EMUI (hold 3 Buttons) and worked so far but when I turned on I was stucking on the WIFI+. Even pressing the button -> further nothing anymore. So I thought -> maybe another stockfirmware useful.
Again C900B300 and then I think I did the big mistake. Took out the sdcard during it was rebooting (HUAWEI was already visible) and now it is big crap. Stucks at HUAWEI. Turning off not possible. This EMUI is not possible anymore. Just with a trick I am able to get into fastboot. Yeah. But what then? Reading TRWP which I know from Samsungs but putting it on with ODIN. ODIN doesn´t work with Huawei. Do I Need TRWP to get it back to normal Firmware? Mobile phone was never customized or anyhting else. just normal stock was on it and is the wish to get a clean back. Resetting to factory was not possible anymore.
So my questions, even I know it is my fault. Any rescue possible?
What could be the best stock Firmware. I Guess it is a single sim from Austria unlocked and unbranded. Would also take Nougat again. Just wanted to get it back to normal working and now I guess I have a big letter holder. Model from the backside is VNS-L31. More I don´t have.
Thanks a lot for any help for my being an idiot. Samsungs are much more easier than HUAWEIs.

Blimey mate,
This really just boil down to what partitions were damaged in your case- Most likely your system and data,
however since you are still Technically running unmodified emui you could manage to sort of salvage it.
The logic is this:
Most custom roms for the p9 lite build on top of emui (patching the system image) rather than replacing it (like the way samsung smartphones do)- so you could flash the rom, it would wipe your phone clean of viruses in the process and then proceed to do a hard restore back to emui.
1.) get your phone into fastboot and flash this twrp http://www.meticulus.co.vu/p/forum.html#nabble-td27
2.) Then flash this rom : http://www.meticulus.co.vu/p/ressurection-remix-for-hi6250-devices.html MAKE SURE YOU FOLLOW THE INSTRUCTIONS ON THIS SITE VERY CAREFULLY
3.)Follow this guide to do a hard restore https://forum.xda-developers.com/huawei-p9lite/how-to/tips-revert-custom-rom-to-official-t3668413
good luck!!! if you have any questions hit me up!

Hi
Hi Exiatron00,
thanks a lot for your maybe solution way. Will do it this evening after work and come back.
Hopefully it works cause as mentioned in other threads -> don´t think that the original owner opened the Debugging so that I can work over a tool. FRP locked is in fastboot. This was already mentioned in other posts which I have read here in the forums.
Thanks for your step by step explanation. Will do it. Hopefully it works. I am really pissed of my own that i was unpatient with the sdcard. That´s a mistake which shouldn´t happen. Anyway it did. So i will try to do everything to get back working again. I am from IT so I am not such a DAU but newbie with HUAWEIs. Most are Samsungs.
Will give Feedback.

If u need to transfer files , just boot into twrp (it has built in mtp support) , then transfer the file from ur PC to phone via a micro us b cable.
If you are unable to fix the phone I do actually have a FULL twrp backup of my phone (EMUI 5- single sim Europe VNS- L31 C432B370) hit me up if u want it.

Hi,
well adb for flashing not working as device not found. Hi Suite installed. Guess that the USB Debugging is not enabled. hrmpf.
There is a similar thread of somebody with no enabled USB Debugging.
https://forum.xda-developers.com/nexus-4/help/fastboot-recovery-remotely-enable-usb-t2177440
He writes an solution how to enable in fast boot mode with using N4 toolkit.
Search for a p9 lite toolkit and found this
https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
may could work?
Big **** -> as Long as USB Debugging is not enabled as Long I am not able to Flash TWRP over adb.
If I connect to PC Hi Suite opens automatically. So driver should be fine as pc recognize the phone.
hm?

Got it working somehow

Hi Exiatron00,
got it working somehow!!!!
Bought a 3 day licence for DC Phoenix where you are able to put Firmware even in fastboot with FRB lock and no USB Debugging on.
So I got the IMEI and Fitting Version which is a L11.
Downloaded it original from Huawei as I still want a original stock Rom not customized which was
HUAWEI P9 Lite Firmware (VNS-L11, Android 6.0, EMUI 4.1, C432B161, WEU) only wokring one.
BUT the big Problem is that the apk Android System Web View is missing in the ROM. A known Problem by HUAWEI. Yeah now I am stucking in the Setup wizard like this guy who mentioned also the solution whell the reason of this Problem.
https://forum.xda-developers.com/hu...stuck-initial-setup-upgrade-to-t3498097/page2
So my question now. How do I get the apk on the phone still no USB Debugging? Does anyone have this Version original incl. this apk? Maybe an img. from a running working System?
Only way I am able to put the Firmware on is DC-Phoenix. It is valid still two days. Maybe someone can help me? Please?
So an Image of VNS-L11, Android 6.0, EMUI 4.1, C432B161, WEU incl. Android System Web View, so that I can go ahead and use the phone again please?
Thanks a lot.
Kind Regards.

Update to Android 8.0 Oreo

Hi all,
I'm on WAS-LX1AC432B184 and i can't update via OTA because "no update" and I think there's update as a friend of mine has the same phone but different build numbers as i needed to unlock my dual sim capability.
When i bought my phone i could only use 1 sim then i changed it to a dual sim. Can this be the reason why i can't get updates? The guy that did the dual sim conversion told me that i will be able to get updates as normal but i don't at all.
Please help me get the latest update so that i can enjoy the new Android – 8.0 Oreo

Hey there, by looking at your build number, you've got a 3GB RAM variant (LX1 instead of LX1A) Dual SIM (even build number) P10 lite on the global cust (C432).
The strange thing is the build number, stuck at 184 when Nougat arrived at B209/210 (Oreo is at B360/361).
Maybe you did some kind of modification (root, bad EMUI flash in the past) to the system so you can't receive official Huawei updates via OTA?
Have you tried clicking on the top right in System Update > Download latest full package?
Just some guesses here…

Probably, the you're huawei p10 lite dual is a branded? Usualy these models is the very slow for porting major release.

Hi zYoshi,
the download latest full package is greyed out... i have done a dual sim conversion in the past not sure if it was done correctly but i got it done... is there anyway i can fix this?
I want to get new updates for my phone to be honest.

Hi sham_1
I sent you a guide wrote quickly in DM (for anyone who might need it, I left it here).
One quick question, now you have an even build number, right? That means that you are on a Dual-SIM firmware.
I suggest you to follow these steps and maybe wait some weeks because I did something similar too while Oreo was hitting Huawei's servers, but I received it only a month later, when the IMEI finally matched my firmware (the IMEI has to be approved in order to receive updates, suggest to "check firmware availability" on Firmware Finder).
"Hey,
I'm not so experienced in Huawei modding, but I managed to debrand my device from C55 to C432, so maybe it's worth a shot.
•
Anyways, try this:
- Download Firmware Finder from Play Store
- open it and click on WAS-LX1C432
- search for builds like B210 (must be an even number and not an Oreo B361, otherwise you can brick your device) choose a FullOTA
- click on update via proxy/DNS, follow the steps on screen
•
The important thing here is to know if the phone grants you into updating with that build, then failing in erecovery (detecting an error, no brick) so that you can reboot with not updated firmware and do a standard System Update from the settings, that update will contain the same build that you've got installed, but it will be used to basically overwrite everything without losing any data, even thought I suggest you to do a backup.
•
Before doing any of the steps I gave you, could you please describe me what you did, what method did you follow?
•
In this post, I am giving steps that worked for me when I had a corrupted firmware, but your problem may be different from this.
Check also the HWOTA method (to solve the same problem but with the warranty void, I suggest to use it only if the above method doesn't work), search "HWOTA P10 lite" on Google for more info.
•
Hope this helps

Huawei P8 Lite (2015) V100R001C69b130 Firmware needed.

Hey folks, I know I'm shooting a very long shot here for some luck, BUT, I am in the need for a stock ROM for the following device that just recently came into my shop and I can't seem to locate a valid DL link anywhere on the net for it (every alleged link seems broken). I seem to only come across other variants and sadly, I don't know which, if any, are variant compatible. The device currently is not bootable as it's stuck in Function 10 error (failed boot image) and doing the hard reset/device wipe does not correct the issue. So I'm hoping someone out there might have a backup of this ROM. I've also tried using every variant of the Huawei HiSuite to recover but they all say the device is not compatible for system restore support. The Bootloader is locked so I can't fastboot restore the device. The info I gave here I obtained using fastboot commands I found in a post here. I appreciate any help you guys can provide on this little problem.
Details are as follows:
Huawei P8 Lite (2015-10-18)
Build: V100R001C69b130
Region: Mexico
