Used phone, bypass Factory Reset Protection? - Samsung Galaxy J7 (2017) Questions & Answers

Hey, I recently bought a used phone(J7 Sky Pro, didn't see any where for this specific model), and when I boot it, it asks for a google account from the previous installation. Is there any way I can break through this?

I don't know how to bypass but you can hard flash Rom with Odin from Computer, all data and system info will full delete and Odin will flash full new system and Google Accounts nedded will remove
But It is not the best solution, you can still get stuck after flashing the new Rom, The best way is to install TWRP (there are a lot of instructions) and Wipe the whole then flash Rom via Odin one last time, it will terminate the Google account request.
But the best way to make your device work best and most effectively is to install TWRP and install custom OneUI Rom by the Modder, it's better and more efficient than Samsung's original Rom for J7 Sky (Why is there J7 Sky Pro, I've never heard of it, I only know about J7 Sky)

I'm almost completely inept when it comes to phones, is there a guide by someone I could look up for either of these processes?

[Q] Quick Question If Someone Has a Moment, Please

I just swapped from my Amaze 4g, to a used Note 3, and I'm a little lost as far as where I should start.
It says that it's on 4.4.2, and that I cannot update due to a modified system.
Basically, I would like to get updated to 5.1.1 (or as close as is official for the Note 3), and root it.
I'm afraid I'm not familiar with Samsung devices, and because I purchased this from ebay, I don't know how to tell the exact state that the former user put it in (I expected they would return it to stock prior to selling).
It's currently a T-Mobile branded, SM-N900T, on 4.4.2, build is KOT49H, security software MDF v1.0 release 2. Kernel is 3.4.0-660648.
It is supposedly unlocked for carriers, though I have not attempted a SIM card use yet, until I can tell that what I have is a valid device and the IMEI is checked out.
Any thoughts on how to validate the IMEI, and sort out how to get my new phone up to date would be appreciated. As I stated, I expected the vendor would have returned it to stock, but that is clearly not the case, so I don't want to accidentally boot loop it by doing something I shouldn't. I have not owned a Samsung before, so I want to be careful on how it differs from my Nexus 7, Amaze 4g, and Droid X, as they're all obviously very different in the OS area.
Thank you for the help1
Download tbe stock 4.4.2 rom and use odin to install. Then you will get the OTA updates.

There is no stock 5.1.1 for note 3, only cm12.1/ aosp. Latest is 5.0 and you can use odin to flash. Maybe it's rooted that's why you can't update.

Some apps to install from Play Store...
Phone INFO Samsung - this will tell you all about your phone and the firmware etc.
Root Checker Basic - tells you if you are rooted or not.
SuperSU - this is so valuable you should buy the Pro licence. Chainfire does some great work for our phones.
TWRP - I have the zip version on my extSDCard and an Odin version on PC in case I have to rebuild from a Stock firmware. CWN works OK but most ROM builds seem to be for TWRP I think and a backup from one will not work on the other.
I don't know your previous phone so you probably need Odin v3.09 - this sits on PC and lets you flash firmware to the phone. (connected by USB)
For which you need Samsung USB drivers so the PC will recognise the phone. Install on PC before connecting phone.
Then do some browsing and find the processes to root your phone and install the ROM you want. If you just want Stock and access to all your phone, you can root it after flashing the original v5.0 download (from Sammobile or similar site - note on Sammobile you need a free account to DL) and then install Custom recovery (if wanted - it WILL trip the Knox flag but that may not matter given it's 2nd hand and might already be tripped anyway)
Read, make SURE you understand what is being said BEFORE you do anything - ask if you don't.
Good luck...
N9005 Lollipop brick
Hi All, just need a huge help here, a friend of mine has been using a N9005 which was auto restarting, she went online and downloaded this firmware...N900AUCUEOC1_N900AATTEOC1_N900AUCUEOC1_HOME.tar.md5....2.5GB in size...and flashed it, but the phone is stuck in boot loop even after recovery wiping data and cache, the phone can boot into download mode but re flashing the firmware always fails.....is there a solution for this.....please help
Thank you all for the info, especially the detailed info from Journyman16. I checked, and it is flagged as custom, which is fine, so I'm going to go ahead and try to return to mostly stock, update it, and root it.
Ok, everything went well. I had to do two attempts at rooting, but I think it's just one of those things where sometimes it doesn't restart into the process every time.
All seems good. I'm on 5.0, rooted, busyboxed, and smooth sailing.
Thank you all, again, for the tips. The Note 3 is running very well. Thank you to all of the devs that have made this process so refined. I've donated to you before, and did so again today. It's outstanding to have such well versed coders, on XDA, helping out the community.

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.

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

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

Galaxy S5 G900F XXU1POJ1 - Need help & advice ROM/Root

Hello,
as thread title says, I need some advice from professionals here for my new Galaxy S5.
Well it's not quite new (almost 1 year) but never rooted it or flashed it, so I still got OS (original system) by Samsung.
I am a pretty amateur on such stuff. First I need some advice what to do: Rec & Root or flash custom rom?
Followng things are important to me:
The System has to be stable and fast: no lags, no crashes, no errors (I do not expect 100% stability, since not even OS is 100% stable, but it has to be at least stable as OS or even a bit more)
I need features and nice widgets (Rom must also be afordable to other apps and widgets, I 'd prefer Samsung OS widget)
I need good quality on camera (preferred OS cam software and features)
Good signal and GPS (Good and fast GPS is a MUST!!, as I use often Navigon when I travel with my car)
Good video player and galery app (Preferred Samsung OS Galery App, but video player can also be different than Samsung OS Video Player if its working fine)
What I do not do with my phone:
I do not play games
I do not read e-books
I don't understand the purpose of KNOX! Do I need it really?
Here are some details of my Smartphone:
Model no: SM-G900F
Android version: 5.0
Modem version: G900FXXU1POJ1
Kernel version: 3.4.0-6364590
Build number: LRX21T.G900FXXU1POK5
Securitysoftware version: MDF v1.1 release 4 / VPN v1.4 Release 3
I would be greatful if someone could give an advice if it is worth to flash a custom rom and if yes what rom based in what moden and kernel versions or if a simple root with recovery install is enough?.
Thanks in advance
Regards
Hi @GordonSpace.......
Most of what you said in your post leads me to believe that there are many things about the stock OS that you are happy with. That being the case, the old adage 'if it ain't broke, don't fix it' comes to mind.....meaning (for now) you might as well stay with stock. If you start flashing CM custom roms (for example) you will lose that look and feel.
On to your question about Knox.....
In a nutshell, knox is based around an 'eFuse' which will trip or blow as soon as you modify your device. This eFuse CANNOT be reset. Samsung are, in some cases, denying warranty repairs on devices where knox has been tripped.
So basically, as soon as you flash CF Root or TWRP to gain root, your warranty is void (Samsung normally provide a 2 year warranty on their devices). Tripping knox will also prevent future 'over the air' updates. So even if you unrooted your device you would be stuck with the version of the OS that you have on your device. Finally, tripping knox will prevent your device from connecting to 'business enterprise secure' servers. So if you currently use your phone on your employers network, this will no longer be possible.
If you still want to go ahead and forget about knox, this is the easiest way to gain root......
Follow exactly....
1) deactivate 'Reactivation Lock' (can be found under Security in Settings).
2) copy SuperSU zip to your device.
3) boot into download mode.
4) Odin flash TWRP 2.8.7.0 (specifically this version).
5) DO NOT allow phone to boot, (uncheck auto reboot in odin and if necessary remove the battery as soon as the TWRP flash has completed) then.....
6) boot directly into recovery. (Vol +, Power & Home button combination)
7) flash SuperSU zip.
8) boot device as normal.

When you have root access, you can get Titanium Backup from the playstore and freeze/delete the 'bloatware' that comes pre - installed on Samsung firmwares.
That will then give you the stability of the software designed for the phone coupled with the look and feel that you like, but without the resource hogging rubbish that most people with unrooted phones have to put up with......

Hello keithross and thank you for your response.
I use my smartphone only in private.
However it still has 11 months warranty by Samsung. Another Idea I had was to sell my Galaxy S5 as it is (OS and Knox) and buy another smartphone.
However what would be your recommendation for a new smartphone?
I was thinking about LG or HTC. But I'm not sure about to purchase a "famous" brand device or just a cheap one like Mobistel, Huawai and such.
What is a nice smartphone to have it root / flashed?
Regards
Kiri
I have about 9 months of warranty left on my phone....but I was able to root without tripping knox.....simply because I rooted before I allowed my phone to update to Lollipop (I rooted with Towelroot while running KitKat) then debloated, and customised the stock firmware.....so I have my phone as I want it, and still have knox intact.
The S5 will probably be my final Samsung smartphone, but as of this moment, I haven't given much thought as to what I'll replace it with. I'm half tempted to keep it beyond the end of it's warranty and start trying out custom roms at that point. It does everything I want it to do, so why would I need to replace it?
On the other hand, if i did replace it, I'd probably stay with one of the well known brand names.....The chances are that they'll have more dev support than the less popular makes of device....but I won't waste my money on any more flagship devices, I'll probably look at the 'upper midrange' devices as they'll (by that time) probably have similar specs to my current device (the way technology is currently advancing, they may even be superior to the S5)......

CyanogenMod
I decided to flash cyanogenmod snapshot
1. However I do not understand the difference between klte and kltedv rom (kltedv = vodafone. does that mean my provider has to be vodafone?)
2. TWRP or Cyanogen Recovery?
3. Do I need to install a diff Kernel version?
4. Anything I should take care about before I flash? (something special about Samsung drivers, kernel, odin etc...?)
Thx for your support.
1....In all honesty I can't answer having never flashed custom to my S5.
2....TWRP recovery over Cyanogen recovery....Every time. Cyanogen recovery is little better (if at all) than stock recovery.
3....flashing a different kernel isn't strictly speaking necessary....unless you want to be able to change processor clock speeds and voltage and apply various other specialist 'tweaks'.....
4....after rooting (but before flashing) make a backup of your EFS folder (critically important) it contains, amongst other things, your IMEI number. If this folder becomes corrupted, you're in a whole world of hurt....
Back up any personal data that you can't afford to lose....things like photos etc.
Make sure you have a copy of your current firmware available....If it all goes pear shaped, you'll possibly need it to recover your phone.
The version of Odin that has most compatibility with the S5 is v3.10.7 though other versions *should* work.
Get hold of and install the Samsung USB drivers on your pc....They come bundled with Kies available on Samsung's website. (If you install Kies, you will need to use task manager on your pc to kill the kies processes prior to flashing anything with Odin).
Use the usb cable that came with your phone when connecting it to your pc.
Make sure you've disabled your firewall and antivirus before attempting to use Odin.
If you need any more help just let me know by commenting below.....

Hey thanks mate. I rooted my device with CF autoroot via odin. I read that CM13 with Android 6 is as a stable version out now. Probably I am gonna flash it. However, I have a question with my current root of S5. Currently the wifi passwords are being save as an encrypted hex key in the wifi_supplicant.conf file. However I would like to use an app that saves and shows my wifi passwords, but unfortunately due to the encryption of S5 it's not a help for me. Any recommendations what can I do to save the real PW instead of the encrypted key?
Sorry fella....The tech aspects of your question have gone right over my head like an international Jumbo Jet....I have no idea what you're even asking about, let alone how to solve it for you. Your best bet would be to create a thread specifically for this question.....you will probably get more views for that thread than for this one.....sorry mate....

You should already know the passwords if they are your routers/APs
I don't know my passwords. The thing is, that sometimes we go to some cafés and such where I have saved the PW of the router, but sitting with friends some of them do not have it to connect with wifi. Thats why I am asking if there is a possibility to view the passwords I saved in my wifi connections (not as a hex key but the true passwords). Anyway.. thx for help. I guess thats Samsung OS. Hope it won't be with CM13 like this.

Is my SM-G530T bricked?

Hello, I'm a total novice when it comes to android modifications and whatnot, so I'll make this to the point.
I was trying to help my dad uninstall the bloatware on his Galaxy Grand Prime (running Lolipop 5.1.1), which includes some of the apps listed in this thread: https://forum.xda-developers.com/grand-prime/help/bloatware-apps-t3079843
I used Kingoroot (which I read worked with mixed results) to one-click root his phone and used Root Uninstaller (https://play.google.com/store/apps/details?id=com.kunkunsoft.rootuninstaller&hl=en) to uninstall Samsung Account, Samsung Push service, Samsung Billing, Galaxy apps, and TMobile TV. Root Uninstaller said it required a reboot to uninstall packages so I rebooted and was greeted with a never-ending TMobile splash screen that would vibrate 4 times every 10-ish seconds. I cannot boot into safe mode either as I've tried the methods shown on TMobile's own website to do so with this model to no avail.
I've tried looking up the vibrating splash screen and some said that means it's bricked.
Is there any way to fix this without any loss of data?
Thanks.

Does that format the storage to do so or does it simply restore it to stock 5.1.1? I have no idea how to flash ROMs so pardon my questions.

No. It shouldn't format SD card storage or anything in sort. Although after flashing the firmware still doesn't fixed the bootloop issue your having then only way is to hard reset everything (which will wipe everything from data to storage files).
Check out this thread for flashing ROMs. It has great instructions for even beginners or noobs.

[HELP] Samsung SM-G950F system & Os recovery ?

Hello,
Here is my problem.
2 days ago, I wanted to root my phone to get rid of any Google stuff (at this point I didn't know the existence of ADB commands :crying: ).
I followed a step by step youtube tutorial (youtube.com/watch?v=ZD-5twDm6XI), which works with TWRP, magisk and Odin (factory reset is needed).
Once everything is finished, my phone is finally rooted, and I grant superuser rights to Titanium app to uninstall google, and only SOME apps uninstalled totally (maps, chrome, facebook) BUT google play services won't uninstall. So, I try with System App Removal to uninstall google play stuff, and the same happens.
I reboot my phone, and it seems that everything disappeared... Not so sure... Indeed, the play store reinstall all applications as soon as I connect to the WiFi! and I have a persistent message "google play services stopped" that prevents me from browsing for example.
At this point, I use ADB commands, to remove anything which contains "com.blahblah.google.blahblah" and the play store (com.android.vending) with -k command. And it worked totally fine !!!!! I disconnect my phone, ready to backup my data. Idkw, i wanted to uninstall system app removal. IMPOSSIBLE from the phone, which says : "samsung One UI stopped" (I was in safe boot mode). My phone doesn't answer, so I reboot it.
Once it has booted, the TWRP menu screen appears. Ok, isn't that weird ? I swipe to allow changes, then I go to system to boot "normally" my phone.
A warning says : NO OS INSTALLED !!!! I don't understand, I panic, but finally boots my phone. Black charging screen. Forever.
I started first to flash an "official" Samsung ROM from Sammobile. TWRP indicates it is an invalid .zip, adb too. Odin doesn't manage to boot from the ROM too. I take a deep breathe and cry. Then I download the /e/ ROM which works fine !! but it has become impossible to backup my data from my samsung account....
So, I came to ask you a few things. WHY did it happen ? How can I be sure that there is no trace of TWRP anymore ? However, my phone storage is 64 GB and there is only 53,5 Gb free of internal storage !? Do you think the original firmware could be "hidden" in my files (e ROM is about 800Mos compressed) ?
It is stupid, but after my mistakes, I miss google...
I will do my best to reply asap.
Thank you for your help !

Google writes and distributes android.
There are many things in android that you cannot remove and still have a viable system.
imho you will have to flash a rom but we need your phones information (found in settings/system/about phone) model, version baseband, etc. etc
Others more knowledgeable can step in and help.

Thank you for your reply ! I've read your article about FRP but I'm afraid it's not my problem...
Here are some of my phone specifications :
model : SM-G950F
version baseband : G950FXXS8DTC1
OS : /e/ version 0.9-p-dev-dreamlte (LineageOS API : Ilama 9)
Android 9
I've been digging the web for ROMs but each time I feel unsecure about it (virus, etc...) so I hope maybe you have something trustworthy

I've been browsing through my root files and folders ( / ) ...
So :
/system is occupied with 2.33 GB
/vendor with 577 MB
/mnt with 9.01 GB
/proc with ... 236.9GB but every under-folder is empty... (explanations welcome !)
/storage is empty
If anyone could check on his device (S8 Exynos with android 9.0 Pie and One UI) if the files' sizes approximately matched, it would be great !
The one I just received is G950FXXS8DTC6 / G950FOXM8DTC1 / G950FXXS8DTC1 (after it took the Apr 1 update) so probably identical - a Yateley GU46 6GG UK phone. I am running it on ATT Prepaid(US) , which gave me the Apr 1 update. I don't know its history but it hasn't been modified - knox=0.
What you would need to do is get that zip and flash it with odin, but having no experience flashing the S8 myself, or any idea where to get that zip, I can be of no help to you. (I just came off a moto x4 which I ruined by flashing a couple custom rom's to try to help others on that forum - the blessings of Pie on that device!)(plus, taking the Apr 1 update on that phone requires a factory reset/wipe.) I needed a dependable phone here and in Europe on vacation.
Keep posting and ask someone to help you re-flash it.
EDIT: I wonder what a settings/general management/factory reset would do. But don't do one until someone here much more experienced with the S8 suggests it.
EDIT: WARNING WARNING WARNING -> Before flashing, ACTIVATE PIN in "Secure startup" (You'll be asked for it AFTER flashing!)
lockscreen and security / secure startup / require pin
I also see a note to delete your google account before doing this. Don't know if necessary.
EDIT: I believe I have found the rom - see pic This is from the SamFirm exe. 0.3.7 I put VOD for the region.
Remember: don't do anything with this until someone experienced in S8 tells you to!
Hi KrisM22,
I've already flashed with Odin, and I have talked about this on different forums, seen tutos on websites,... I hope this time it will work
I have the ROM required, selected activate pin, followed step by step the recommendations, and if I figured it out I will keep you up to date !

Excellent! What ROM did you flash it with?

I flashed a ROM from https://www.imei.info/download-firmware/samsung/samsung-g950f-galaxy-s8/SM-G950F/ , then I just followed the steps and flashed with Odin. TWRP has disappeared (the classic recovery menu came back). I think I have found my issue with the "no OS installed" bug : it could be because I deleted the essential API com.google.android.packageinstaller, what may have prevented the phone from booting and launching the OS and its apps .
I should have read this excellent post before...
*I ran antivirus analysis with virustotal and Bitdefender, which both declared the extracted files were safe : I didn't notice anything different by my phone compared to the original OS too, so...
