Galaxy Tab A 10.1 2016 (blocked by Chinese firmware) - SM-T580 - Samsung Galaxy Tab A series Questions & Answers

Hello everyone, I flashed the stock firmware (T580ZCU6CTA) to my SM-T580 , trying to "fix it"; all the memory was occupied by the system files. The flash went well, still when the tab rebooted the screen went crazy for a while, anyways after booting up the tab works way better than before, but its block, meaning that it wont let me install some apps, I also tried to flash many different stock firmware but I always get a message that the boot-loader is block (in Chinese language). I was able to flash the U6 combination files, but it did not fix it. Please I need some help.

Did you enable OEM unlock on the Chinese firmware or the U6 combination firmware?
Edit: I forgot that the Chinese firmware had Crom Service...

Hi JJcoder. I actually did enable OEM unlock on the Chinese firmware and had no luck. While in the U6 combination firmware; for some reason the "OEM unlock" option is not available even after enabling the developer mode menu.

Hello! The problem is that in the Chinese version they install a thing called crom protection.
To deactivate it you have to install an apk on the tablet called "crom service" and do the steps that come on this website https://www.teamandroid.com/2018/06/27/unlock-bootloader-chinese-samsung -devices-crom-service /
It has worked for me, if you realize it, before using and entering bootloader mode you get "CROM SERVICE: ON"
then once done the steps you will get "CROM SERVICE: OFF"
when that comes out install twrp and from there install the rom you want. If you have problems reinstall the Chinese version with odin and do the same again. Sorry for my bad English!

Thank you so much for your help; everything went well. I had a little problem trying to get the tablet into recovery mode after installing the TWRP, but I found a solution (when the TWRP flash is complete and the tablet starts to reboot, press and hold volume up and home to get it to boot into recovery, this has to be done quickly in order to catch the beginning of the tablet rebooting or the stock recovery will overwrite on the TWRP). I had to mentioned just in case someone else runs by this problem.
Please reply with your pay pal so I can buy you a beer for your help. Thank you.

hahaha don't worry!! I had the same problem and spent several hours researching because I couldn't install twrp or another rom, so you don't need a beer, I just need to know that it was useful and someone else didn't have to go through the same as me XD

[Q] Locked Out of Phone by PIN! + VPN Setting Errors

First off, this started with a possible error which I will describe incase anyone else encounters this problem with the SM-G9006v by China Unicom
I added my VPN and of course set up a PIN number. I didn't actually use the VPN for a few days, but when I went back to check on it the VPN had disappeared. I attempted to add a new VPN and it appeared in the box area for about a second and then also disappeared. I think it was at this point that I saw my first "Settings has encountered an error" message. The settings window sort of flashed and reloaded. I then went to the Lock Screen area and attempted to remove the PIN number, but was unsuccessful as the other less secure options were greyed out. At this point I pressed setup Password. The password screen came up and I started to enter my information when I received another Settings Error.
So, I am currently faced with a PIN lock screen that does not respond to my original PIN. My phone did not have USB Debugging Set and Reboot Lock is enabled, so I cannot enter recovery to factory reset my phone.
Solved By: Flashing a new Recovery via Odin, Please Note: You might need to use VolUp+Home+Power Button rather than VolDown+Home+Power Button

I have no idea how to solve this problem, I have tried:
Millions of pins
Flashing a new Recovery via Odin (Passes, but nothing loads)
Using Flashboot & ADB (device not found)

Yeah, I can't figure out how to get into that recovery mode. It freezes after:

If anyone has any suggestions...?
I got locked out on my Note 3 from a kernel/rom issue. Only way I could fix was flash stock Via Odin.. Seems like that's the method you'll have to take also.
I was able to solve my problem by flashing CWM via Odin. I thought it hadn't worked because I was using VolDown+Home+Power.
It worked when I used: VolUp+Home+Power

Could you link what CWM you used? I can't get my phone to recognize by Odin... or perhaps link how you did it. I would like to drop a custom rom or at least have a recovery that can flash gapps (default recovery fails to flash them for me)

You might want to look at this post on a chinese forum http://bbs.gfan.com/android-7340315-1-1.html
It worked for me, but tripped Knox.
One extra step, not sure if it was necessary, but I installed 豌豆荚 pinyin: wandoujia on my computer, then hooked my phone in. I'm not entirely sure, but I think it helped install the drivers, which might be the only problem.
As far as getting gapps, I'm still working on that too. I put in a few apks to my phone, but gmail and play store are still broken....

Much appreciated! I don't speak Chinese and those around me that do aren't technically inclined. I don't even need a custom ROM if i can get gapps working.
I used a site to download apk's off google play store (website version) and it worked ok. Doesn't work for paid apps, but at least i was able to get google's translate / etc installed. Google translate wouldn't let me load off-line languages though sadly.
When I attempt Odin to flash a recovery or any other file, it won't reboot the phone, then in the stock recovery, odin doesn't see the phone, been a touch of a roadblock. I'll be sure to look into those links.

My recovery ended up being Vol++Home+Power and download mode being Vol-+Home+Power. You might wanna just check that to make sure recovery isn't hiding there.

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.

i have same issue here, did you find any solutions ?
AFAIK when you factory reset your phone etc. if rooted you must remember to go back into Developer Options and re enable OEM Unlocking. This depends on the method you used to root, if you flashed dm-verity then you "May not" have this issue but cannot say for sure.
If it is already too late for you then I think you need to flash stock via Odin, plenty of threads out there on where to find the firmware (SamMobile) and how to do it. Even a quick google of the error gave me plenty of results...
One thing I have read is that you may have to keep trying to get your phone into download mode as the timing is much stricter with this error message.
I've the same problem with my g935x blocked on FRP when ii treid to root if any one can help .plz

@djluisbento This method seems to be interesting. But would you please clarify more about it. How to install the apk file on official recovery? Or it's enough to have the pendrive connected? And if yes, when this step should take place, after flashing the official ROM or when?
I'm stuck in a boot loop into recovery mode with dm-verity error, and unfortunately I have the FRP locked, so I can't install TWRP to flash the no-dm-verity.zip file to skip it.
Appreciate your suggestions.
I have the same issure. stock firmware wont install either. im just stuck on the FRP screen, cant even get into recovery
Same issue here, please help
Everything was fine with rooting and installing TWRP. after that did a restart/ attempt to goto twrp recovery, from then the s7 edge is stuck at "Custom Binary Blocked By FRP" and doesnt boot. please help!!
Have you do a Wipe then Format Data.
Then flash the no-verity-opt-encrypt zip in TWRP
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
If you want to be rooted with SuperSU:
Download the latest SuperSU by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
If you only want a bootable system partition or writable data in TWRP:
Download the latest dm-verity and force encryption disabler zip.
Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.

Yes, flashed both Zips in recovery. I used my regular google account during the initial set up. If i wait for 72 hours, will the phone just boot back online just fine? Still, how do i make sure it wont goto the FRP lock again while trying to reboot or reboot to TWRP?
Solved,
Flashed with stock firmware, logged in with same google account, rooted with TWRP, installed Zubi's sound mod. Made sure to keep the 'OEM Unlock' stay turned on.

But U did this after 72 hours?
There are several methods depending on firmware version installed on your phone. Basically you have to enter in your phone, launch chrome, install an app which gives you the possibility to log into your google account from chrome and not set-up program.
I used successfully the Bluetooth method. Search for with google. You need a bluetooth headset and follow the steps described on youtube.
BTW. My phone was brand new and I flashed different official samsung firmware ( csc). I had to change google password in between and that resulted in FRP lock....
The wait time is 24 hours as is stated in google docs from site

Hello I have a related problem, opened a new thread, but my thread was closed, because my problem is related to this one, but more complicated. I have the same problem with FRP lock as described here, I can turn on the download mode but it wont be recognized by my computer. I tried different usb cables, drivers, even computers, it wont help. I cant flash it with odin, smartswitch, kies, no matter what I try. If I go to recovery mode it says `dm-verity verification failed...`and if I choose `apply update from ADB or SD card` it says `update from external storage disabled`. I dont know what to do anymore Its a new phone
FRP Block - no Dev Tools enabled
Hey guys,
you're my last resort, I've tried everything I happened to come across, to no avail.
First off, I did something incredibly stupid, don't even ask me why, as I have no idea what the heck drove me to do this in the first place.
Anyways, I was using the stock ROM on my S7 Edge, not tweaked or tinkered with besides the usual CF-Auto_Root. It never caused any trouble whatsoever. But for no reason at all this morning I decided to disable USB debuggin and OEM unlock. A short while later I rebooted my phone, which ended up in "Custom binary blocked by FRP Lock".
I gave a factory reset a try, but that obviously didn't change a thing. So I went to sammobile.com and downloaded the latest official stock ROM for my device and tried flashing it with Odin. Unfortnately Odin always fails with "Complete(Write) operation failed.", which I assume is because I messed with the settings in dev mode.
Next stop: ADB. I've never used that thing before, but I thought I should possibly be able to get it done following a simple guide. Unfortunately ADB won't even list my device when typing "adb devices". It's just an empty list.
So please guys, give me some tipps on how I can bring my phone back to life.

(Soft-)Bricked S7 Edge/G935F with FRP lock & DRK error, but no root/OEM unlock/ADB

(Soft-)Bricked S7 Edge/G935F with FRP lock & DRK error, but no root/OEM unlock/ADB
Hello guys,
I bought a, what I thought to be, soft bricked S7 Edge (G935F) from the bay. It was listed as having sw issues, so I thought I could easily fix the issue myself. Stupid me, this one really isn't easy to fix. I've tried a lot of different hints that I found meandering around the web, but none of them have proofed working so far. I would appreciate some help because I don't seem to be making any progress.
When I got the phone, it would boot directly into Android Recovery with a dm-verity error on the bottom.
Below is what I have tried already:
1 . First I did the obvious, factory reset and wipe partition. No change.
2. Downloaded the latest firmware with updato (SM-G935F Region DBT) and flashed with Odin. It then booted into a screen with a hazard sign and a DRK error (Device does not have DRK, please install DRK first. press any button). Then returned to Android Recovery with variations of the DRK and dm-verity error messages
3. I flashed the same firmware again. This time the phone booted up to a Samsung error that said to use SmartSwitch's Emergency recovery. I tried but it asks for a recovery code and I don't have one.
4. I used an older version of SmartSwitch which gave me the initialization option where you need to input the device model and SN - SmartSwitch decided not to cooperate and noted that the S7 edge does not support initialization
5. I tried to flash CF-autoroot but it gave an error in Odin and failed because it is "Blocked by FRP Lock". I can't boot normally into android. Any workaround?
6. I used a dm-verity workaround file (G935FXXU1DQC4_FIX_DRK_dm-verity.tar) to actually get the phone booted up- but then it asks for the account information to do away with the FRP lock. And the former owner does not want to give me his login information. In addition, none of the workarounds (bluetooth, modem terminal prompts, etc.) did work.
7. Flashed oldest Android version I could find for the G935F - 5.1.1 - this gave me a prompt right after reboot that looks like the password request for encrypting memory. default_password and variations did not work. I am still stuck with...
No Support SINGLE-SKU
Supported API: 3
dm-verity error...
failed code : 0x02
...in the recovery
8. I flashed the combination file and was able to boot into Factory Binary and used the IMEI recovery option which is supposed to fix also the DRK issue. No luck.
So, this is where I am right now. If anyone out there still has sparks of hope, I would be delighted to hear about them.
Thanks much in advance!
Conversion software and ADB Shell
Small update - I booted into factory mode again using the conversion firmware. This way, I could connect to the device via ADB and use ADB shell. There is a guide (here: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516) which guides through IMEI recovery using the conversion software and factory mode - that is supposed to also help with DRK issues. Did not work for me.
Another great guide (here: https://forum.xda-developers.com/no...fix-drk-dm-verity-factory-csc-serial-t3422965) used ADB shell to push and repair the DRK with some additional files. Since the device is not rooted, I did not get very far, either.
So, no progress whatsoever.
In summary, I can get the device booted up into factory mode using the conversion firmware, or, by using the dm-verity tweaked firmware, I can end up in the Google Account locked part of the initial start-up settings.
Any ideas?
Have you looked at the process to completely re-do a phone stuck in the Google auth log-in? At least that is how I understand where you are stuck. I have a phone arriving soon that I will need to re-flash to get out of that, via Odin.

Hi JeffDC,
Thanks a lot for the reply. How would this process look like? I have flashed the phone with all sorts of variations of Android L, M and N - plus the combination fw and the one with the dm-verity/DRK workaround which at least got the phone booted up. But then I am stuck at the google auth request.
I cannot flash anything custom since the FRP lock is on.
Hence, if there is any other way to re-do the phone as you are saying, I would live to hear about it.

Hi JeffDC,
Thanks a lot for the links.
Link #1: I can flash the file #1 and get the device visible for ADB by using the combination FW before starting the steps. Unfortunately, step #2 does not work due to lack of permissions. I guess because of missing root.
Links #2 and #3: These are the guides I was already referencing in my post #2 - they both do not work due to, I guess, missing root.
Smart Switch initialization
Update: I got smart switch to do the update and initialization for the device. Workaround was to use a different real serial number than the one of the actual device (I can only assume that it has got to do with country presets).
Cool stuff, all went smooth - but, still the same result. The device ends up in recovery showing the dm-verity error (failed code : 0x02) with FRP lock on and no root.

Interesting read, particularly ignoring the trojan squabbling.
Uses script and setup files to get around FRP.
I suggest you to re-try flashing with Odin the Stock Marshmallow Firmware. Then Boot Into Stock Recovery do a Full Wipe.

Thanks for the recommendation. Done that (MM downgrade and full wipe) - same result, still DRK error only booting to recovery.

Hi JEffDC, thanks for the follow-up hints. Very interesting read and approach. As commented in the other thread, I think the package download link in the opening post is dead. I am also curious to see 2 more complexities in action:
1. Will this work on a G935F variant (Exynos vs Snapdragon)?
2. The only way for me to get to the Google Account prompt is by using the modded dm-verity version mentioned in my first post - but I am not sure I can get ADB access enabled simultaneously
Good luck.

Hey sathiere,
Came across this. It apparently removes the FRP before the system can start it up! Let me know what you think. I'm going to try it on a locked Edge next week or two. Seems to go right after the FRP protection file.
https://forum.xda-developers.com/galaxy-s7/help/how-to-bypass-frp-galaxy-s7-possibly-6-t3622126
and the download link works.

Hi JeffDC, came across that thread last night - checked it out, but cannot really make sense of it just now. I will be posting directly in this one in the next minutes.
Regarding the link for the other thread - the google drive link for me shows invalid/no content...

Yes, I am hoping for a response to my post there, near the end, clarifying. I think I get the method, and it's really pretty straight forward, really.
sathiere, I think basically what it does is provide two connections to the phone at the same time, one via Odin, and the other via direct ADB.
Step one is to flash a Universal boot loader, which is unlocked or can be unlocked via ADB. Now with the locked boot loader out of the way, on to getting rid of FRP.
Step two is run the. bat file which deletes the Persistence file, which is the Google encrypted setup file/FRP file. BOOM, FRP gone.
Then either stay on the Universal bootloader, or go back and flash the OEM.
Brilliant!
I have the same problem with a sm930f binary 2 boot loader. Stock Rom doesn't start and frp lock. How you fix it ? Thank you
Try this method

Sm-T580 FRP lock and custom binary blocked by frp. Cant flash twrp recovery.

So im trying to install twrp recovery but when i try to flash it thru odin, i get a Custom Binary (RECOVERY) blocked by FRP lock. I cant factory reset because it also disabled by FRP. I cant verify the tablet because i dont know the account information as the tablet was bought through craigslist. I have tried flashing a stock firmware version and that installed fine, but i still couldnt get past the verify screen. So thats when i decided to try and flash twrp but came into the binary error. I have been trying for the past two days to find a way around the verify identity and the frp lock. I cant enable oem unlock. I have tried rootjunky method but OTG flash wont pull up the file manager when plugged into the tablet. I cant use adb because i cant enable the developer settings because you guessed it i cant get past verify identity screen. Any help would be greatly appreciated.
Sounds like you need to find the Combination Firmware.

I already tried that method but didn't work. It's on android 7.0. I tried downgrading to sm-t580.. XAR firmware 6.1 and it worked but when it boots it goes straight to a black screen asking for a password. I tried the frp call method as well but it doesnt have wifi calling.

It only works with certain versions of 6. The one ending is PL4 is the one you want. The trick is in adding the fake wifi network instead of connecting to your home network. Pay close attention to the beginning of the video.

Okay thank you. I will try that again when I get home. And this works on version 7.0? The device is currently on 7.0 but when I tried the pl4 md5 it flashes it but when I boot up the device it just goes to a black screen and asks for a password. It doesn't start at the setup wizard

You have to use Odin to install PL4. You can't flash it via TWRP. Also, make sure you wipe everything first.

I know. I can't install twrp like I said. I've been using Odin to flash everything. But when I flashed the pl4 file and tablet goes to reboot. It doesn't load the setup wizard. Doesn't show the welcome screen and pick a language. It goes straight to a black screen and asks for a password. Doesn't ask for an email or anything.

Never heard of that. Can you boot from there into recovery and wipe again?

Yea but when I try to factory wipe it says mdm doesn't allow factory reset and reboots and takes me back to that same black screen. I can only wipe cache partition. I will post a picture of the screen when I get home.

I found this site. It is apparently an "MDM lock" and not FRP.

Tried this as well. I did it about 20 times before giving up. I might try it again and do it about 30 to 50 times. If I was just able to get to settings I'd be straight but I can't get to the settings so that's why I'm trying to reset it as a completely new device. Do you know if I could flash the 7 inch tab A firmware onto the smt580? Or flash the smt585 firmware onto the t580 and flash the BL AP and CSC?

From what I've read, Airwatch MDM lock can't be removed by flashing ANYTHING. It is third party anti-theft protection that has nothing to do with what ROM is installed. I know I ran into their stuff a few years ago with a used laptop I bought and only Airwatch was able to solve the problem after contacting their customer and verifying the laptop wasn't stolen.

I did end up finding this. Seems the device is completely locked with no way to get around. When i flashed the device i may have deleted the admin privilages so there is no way of gettting around it as of now. I might end up paying someone to fix it or get around it or i wasted 180$ on a locked device. The guy i bought it from either blocked my number or deactivated his number as i cant get in contact with him. Pretty pissed. Thanks for all the help tho
I had the black screen password happen to me when I downgraded my SM-P580 from Android 7 to 6. Try clearing the cache. If that doesn't work, try reflashing, then turn it off and reboot to recovery and clear the cache.

Do you think if i changed the CSC to a different region on the tablet, and put a unlocked bootloader on it, would it might get rid of the frp lock? Do you happen to have a smt580? If so do you think there is anyother way of getting around this? say if i flashed like your firmware on to my tablet? Im desperate to get this thing unlocked as i would be out 180$ :crying:. Thanks for all your help so far. I really appreciate it man. Thanks to everyone who has helped so far.
Or what if i downgrade it to 6.1 and then downgrade it again to a even farther back version? Do you think this might work and gett me around the black screen? If so then i would be able to bypass the google verify account. Ima go ahead and try it unless its a risk of bricking the tablet completely.
I also read somewhere that if i flash the cp part on odin that it will erase all data. Think that might be worth a shot? But what do i need to insert in the cp slott? I know BL goes to BL and AP to AP and CSC home goes in CSC. So what goes in the cp slot?
EDIT: So instead of putting csc home in the csc slot i put the other csc file in its place. I checked the re partition box. When i did this i got a new message on the tablet in the top left of tthe download mode that says FRP is enabled, ignore PIT download. Any idea what this means?
