Jiayu S3 PIN Locked by Kinguser app - JiaYu S3 Questions & Answers

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

Problems with update 2.3.4. My phone wont turn!!!

I tell you I unlock it first, then I had problems with some widgets and I learned some new updates.
Then, I made a backup with Sony_Ericsson_Backup_and_restore.
After searching, I root my phone with "GINGERBREAK" downloaded from the internet (GingerBreak-v1.20) and finally settled "Titanium Backup" to remove some applications from my operator, then install the CLOCKWORDMOD (do not know what for) and and finally I started to flash ...
After root, flashing with FlashTool_0.2.9.1.
I suggested steps for flashing and inserted this update: "LT15i_4.0.A.2.368_Generic Global", with "wiped ...", which is to delete everything and set it to zero ..
Normal work for me ... I sent version 2.3.2 to 2.3.3 (thinking I would send to 2.3.4). It was great ... Then I appeared a notice of samsung (on phone), to install version 2.3.4 (4.0.1.A.0.283 I think it was that number) and when it started to install warned me he was going to shut down, spent 6 or 7 minutes and not lit. I tried to turn it on and vibrated, then vibrate him again and try to turn rang again, but soon ...
Then I could not turn ...
Once this happened I was like crazy trying to fix the COMPANIOM, but nothing ...
I flash again, this time with this "LT15i_4.0.2.A.0.42_ (1247-1041). Ftf" but did not recognize the flashtool as the first time coming out of the mobile code when you open the program loads and displays the model number of the phone, it did not appear.
Finally, press flash and began. (To this already, before, try reinstalling the Global LT15i_4.0.A.2.368_Generic where my computer does not recognize, nor giving flash, just not recognized out in red letters)
When flashing with the latest LT15i_4.0.2.A.0.42_ (1247-1041). Ftf, the normal flashing until the end. But my phone just did not work. The light that was on the side of my phone was green ...
I sent a technician and he said he could not ....=/
I hope you can help and serve as a case to be resolved.
Thank you very much, good luck!

Oops-a-daisy (flashed wrong version of stock rom)

I wanted to root my Galaxy Note 4 (SM-N910F UK carrier H3G) so I could use the mirroring option in Airdroid.
Long story short, I'm severely disabled so wanted full access to my phone whilst on my pc, without struggling to get my phone all the time. (SWTOR Security Key is one of the many reasons for wanting to not have to grab my phone every time I need to do something on it)
(I can't put phone where it's easily accessible whilst on pc, because of the board I use for keyboard and mouse rested across the arms of my chair)
I THOUGHT I had it sussed, as I had successfully rooted and booted my S3, S4 and Note 2, 3 and 8.0 devices.
However, I didn't read the fine print when using CF-autoroot in that it doesn't work on 5.1.1 atm. Or something along those lines...
Anyway, with my usual eagerness and impatience to do geeky/nerdy deeds, I ended up with my phone in a constant boot loop no matter what I tried.
I scoured the Internet for 3 hours, trying to find the original stock rom for my device and was livid that my usual Google-Fu was failing miserably.
I found one, so I thought, installed the kernel, (couldn't find stock kernel either) installed SuperSU, installed Twprs or whatever it is, (excuse my lack of knowledge please) then installed this "stock" rom.
Turns out it possibly IS the H3G network's Stock Note 4 (SM-N910F) ROM. IF I lived in Italy.
I still would like root access on my phone, but I would like to try and get stock rom back, or something EXCEPTIONALLY similar.
Please, again, excuse my apparent thickness... (and I'm not talking sliced bread here) is it the kernel where rooting takes place, the ROM, or do both have to be involved in the adaptation?
I know very very little about Linux and kernels etc.
I hope that I have described my predicament clearly, and that when one has picked oneself up off the floor from rolling around with much merriment, one (anyone) is able to assist with my screw up.
Best wishes,
(Applebogies for waffling on more than the meat content of a Belgian Blue, (I'm not talking Blue Waffle, but of four legged animals that chew the cud)
(Applebogies also for mentioning The Waffle of Blue-ness in more than one sense of the word, if it makes you Google it and you only just ate and you've never seen it before)
(Finally, applebogies for my rotten and feeble attempts humour, please try to cut through my crap and get to the point ofwhat my conundrum actually is)
So basically in a nutshell, you've bricked your phone? I do know that when I flashed stock ROM the other day, I had to pull the battery, boot into recovery (vol up + home + power) and wipe data/factory reset and wipe cache too. Then it booted just fine try that.
you can find different stock roms for your phone at sammobile (google it) download the firmware from there and flash it with odin. Watch youtube videos on how to flash firmware with odin. its simple
See if you can boot the phone into Download Mode via volume up+home+power. If it boots into download mode that means its not hard bricked. If it doesnt boot into DL the first time you try, do a battery pull for 15-20 seconds, then try again. If that doesnt work, then check your specific device versions forum for an unbrick method, and check for a general unbrick that can be used for all N4's.
If it does boot into download mode, download the stock firmware for your specific N4, flash it via Odin, (instructions are generally included in the thread where you find the stock ROM download) and you should be good to go after that.
Edit: SamMobile does indeed have a firmware for your specific device. Do a google search for sammobile, go to that site, and input SM-N910F into the device search bar. That will take you to a page with a list of firmwares. Theres a list box where you can select your country, that includes country and carrier combinations. Yours will be listed as United Kingdom (H3G)(H3G). Select firmware with PDA version N910FXXU1COJ3.
Not sure why you all think my phone is bricked, I am on it now?
I am however, currently running the Italian version of 3 mobile rom. Looks like asrah has solved that problem though xD
To shorten my previous post:
Where does root happen, on kernel or rom?
Ie - can I have stock rom but still have root access on my phone?
Thank you to asrah for finding my rom.
Thanks all and a very Merry Christmas!

Yoga Tab 2 830f Is there a soft brick fix?

I've searched but apparently it seems like most of the answers have been deleted or redacted.
My problem...
I was just given a Yoga Tab 2 from my sister who has given up on trying to fix it.
The tab was on 5.01 and rooted when she got a system update. She ran the update but now the tablet freezes during/after the boot animation.
It will go into fastboot but is not recognized by ADB.
She tried to install the original Lollipop firmware through recovery but ended up getting a system 7 error.
This is exactly what I see when in the bootloader screen
FASTBOOT MODE
PRODUCT_NAME - YT2
VARIANT - YOGA Tab1
HW_VERSION -
BOOTLOADER VERSION - unknown
IFWI VERSION - Blade_21.x64.0005.R00.1504101447 FFD8_X64_R_
SERIAL NUMBER - BaytrailD454B***
SIGNING - ?
SECURE_BOOT - ?
E: No valid installer medium found
I know nothing about Lenovo and how they do things but I know that with HTC you have to go back to 100% locked and stock before you can install an OTA. If you do try the OTA usually just won't install but unfortunately this thing seems to be at least soft bricked.
Is there a way for me to maybe roll back? I've read about people going back to KK in order to get the LP OTA but all links to the KK firmware are gone.
Thanks a lot, I appreciate any help I can get...
BTW, She is under warranty but of course she was rooted and is worried that repair will cost her almost as much as she paid for the Tab when they realize and void her warranty.
If its the same as the 1050f try these files.

Thank you. I used the Restore KitKat Bios you posted along with an 830F specific KitKat firmware from the Russian Lenove site. Worked fine after editing the flash.xml file to allow for a larger system.img file.
The tablet is now back from the dead. Unfortunately it gets the 5.0 update but fails in the Lenovo Recovery when trying to flash the OTA. It gets to 100%, stays like that for a bit and then a blue X saying flash failed. After that I'm back to a black screen and have to reflash the kitkat firmware to get up and running again.
I have no idea why the OTA flash constantly fails but I guess I have to do a bit more research and hope I can get her up to date.
Did you set the country code , without setting it updates fail.
Look at this advice from ionioni to me about setting the code

Outstanding!!! I entered the code in contacts and it gave me a menu of different countries to choose from. I Chose US and she rebooted, went into recovery, ran a bit and rebooted into another fresh install which looked completely different. We're talking different wallpaper, and different apps. After that it successfully installed 4 or 5 OTAs and as far as I can tell it is now completely up to date!
Android Version is 5.01
Build is S100250-160119
Kernel Version is 3.10.20-x86_64byt-g9f7fad7
Security patch is dated 2016-02-01
I'll wait a few days before I root and install Xposed just to be 100% certain it's up to date.
Of course my sister will probably ask for it back now.
Either way, THANK YOU VERY MUCH corasman!!! Your help has been invaluable!
I am so pleased it worked for you, ionioni helped me so much and now I am trying to do the same for others.

Yotaphone 2 reboots by itself after after the screen switches off.

Hello
I have a Yotaphone 2 running android 5.0. I have a huge problem with the device which is, that the phone reboots automatically all by itself after the screen turns off. The screen timeout is set at 1 minute and once the screen goes off, the phone reboots! I don't know what the problem is but its making me crazy!
Note: The phone does not reboot if the screen doesn't turn off. So I changed the screen timeout to 30minutes. Also note that Wi-Fi doesn't start immediately. It doesn't even start most of the time and is stuck at "turning on"! And also, the phone isn't detecting my SIM Card!
Hope someone can solve my problem.
Wow, seems a lot of problems here. However you provided very few info about your phone.
1) Where did you buy it?
2) What have you done after you opened it, OTA? Which firmware was installed?
3) Have you tried factory reset by wiping data in the stock recovery? (Accessible with Vol+ and Power)
4) Have you tried to flash from scratch the RU .124 firmware with YotaFlasher?
5) The phone was behaving normally before or it's doing this as soon as you started using it?
I got the phone as a gift

-The phone was a gift from "Aramex Company".
-Yes, I have factory reset it! Note: It wasn't possible to reset it from settings because it would always get stuck in "Shutting Down" phase and nothing would happen. So I hard reset it.
-I found something strange going on though. Whenever I reset it, It would restart (after the reset is over) and say that "ANDROID IS UPGRADED TO 5.0".
I think it is upgrading by itself to 5.0.
-No, I haven't tried any flashing.
-Yes, the phone was working fine for a while and then started behaving like this!
Cheers!
(Thank You for your support and attention by the way)

Hello!
I have made a video showing what the problems are! Please give me your e-mail so that I can send you the "Dropbox" link to the video.
Thank You!
I think the first thing to do here is to flash a clean firmware (RU or EU) on your phone via YotaFlasher, search here on xda how, and then report back if it's happen again! Seems that the firmware it was shipped with wansn't so stable.
Flashed it!

Hey!
As you had prescribed, I flashed it! First I flashed it with Android 5.0.0-ME1.1.60 and after opening the phone I used it for a while and the phone was same as before flashing! There was no difference at all! The phone was restarting on turning screen off as usual, the WiFi wasn't turning on, and the SIM wasn't being recognized!
But then I flashed it with Android 4.4.3-S01-003-ME1.0.3.61a and the phone is still rebooting by itself upon switching the screen off and the WiFi problem still persists! The WiFi just simply won't turn on. It's stuck at "turning on"! The SIM isn't recognized either! Also, the phone is restarting from the inside now (It wasn't restarting before. I had to keep the power button pressed every time I wanted to restart)! But NOTE that the phone still cannot be just shut down, it can only be restarted!
I don't know what to do!
Cheers

Hi lgk350tr,
Why are you unable to make yotaflasher work, it is a pretty simple application. Have you tried to see instruction videos on YouTube on how to use it? Instructions are also available on XDA Developers' website. ( https://forum.xda-developers.com/yotaphone-one/general/yota-flasher-download-t3480922 )
Don't hesitate to contact, for any problem!

Try flashing the hybrid modem mentioned in the general guide (Part 2).
Try flashing 2 times before rebooting.
If nothing helps, you could try lineageos, @angelll123 made a lengthy guide how to that in the post quoted here , also check my comment.
Is this what you mean?

I have attached a screenshot of the Yotaphone 2 General guide page, I want to know if you are referring to the text that I highlighted in the screenshot!
Thank You
I do experience similar issue, but only recently. I haven't done anything like flashing or upgrading my phone, it started by itself .
I am experiencing reboots whenever battery drops below about two thirds of its capacity. Also, charging and handling some load prevents this.
Note that my Yotaphone has both displays damaged. Still working though.

Device not starting/black screen after stock-ROM flash via Odin

Hello, everyone,
I tried to install LineageOS on my S10 Plus yesterday. That worked so far, but I found that it didn't have a decent camera app and the Samsung Watch wasn't that easy to connect either. So I thought I'd just go back to the Stock ROM again. I then downloaded the latest stock firmware according to this guide and installed it with Odin. The installation also runs through, after the installation the mobile phone starts and after the start screen there is an Android man with the signature "Erasing". After a few seconds, the device turns off and stays black. Even if I put it on the charger or try to restart it, nothing happens. I keep getting into download mode and recovery, but that's about it. Multiple reinstallations and resets via the recovery didn't help - the phone just won't start.
I used the CSC_... and not the HOME_CSC_... at the firmware is the right one for my phone.
Is there any way I can salvage the device? I'm afraid that something in the memory is defective now, which has nothing to do with the flashing itself. Do you have any ideas?
Many thanks!

I'm glad it worked.
I was very afraid that the phone died, what did you do for 5 days in this state?
Now I have a question in my mind: When Samsung releases an update in the future, will the bootloader and modem files be updated when we update it with odin? won't it be updated? After that, do we will always update manually as twrp? do you have any idea?
Well, I simply didn't use a mobile phone in these days. It was a very "interesting" experience, but not a huge problem. I sometimes opened WhatsApp as Windows App (interestingly, which works without phone).
I don't know, what happens at a Samsung Update, but until Android 13, I will not update (so probatly never). In our German forum (www.android-hilfe.de), a pre rooted and debloated "Stock"-Firmware is provided, but I can't install it, since my Bootloader is too new (V15 instead V14 for the ROM). When it is possible, I will install this firmware. If you are interested, here is the link: https://www.android-hilfe.de/forum/...3-2022-stock-rom-v2-0-pre-rooted.1000713.html
