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.

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.

Had that problem with a brand new phone, just wanted to get into download mode to see if the phone was tampered with and boom, flash screen with the red warning, flashed stock KSA (phone original CSC) , worked and phone was formatted, another surprise was faced, google did not accept my gmail account, had to shut down phone for 72 hours as read in my google search for people encountering same issue, once the 72 hours passed I was able to sign in and using my phone again.

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.

Helo
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.
First excuse me for opening an other thread like this, i think i have read all other threats regarding my problem, but none have the same situation
My Huawei M3 Wifi (BTV-W09) seems semi bricked after installation of Nougat Update.
The Installation (Force Install with dload) gave me an error and also while boot i got the error message: "Your device has failed verification and may not work properly."
I have the option to press "Powerbutton" and the device will boot up. I checked the Version and it showed android 7 + EMUI 5. The only problem was that almost every system app was missing, like keyboard, calendar etc. (playstore was there)
So i tried to do the rollback with:
HUAWEI MediaPad M3 8 Rollback Package%28BTV-W09 %2CC900B300%2C EMUI5.0%2BAndroid7.0 rollback to EMUI4.1%2BAndroid 6.0%29
The Installtion (force update) gets stuck at 5% and after like 3-5 minutes the tablet will boot up showing the same boot error that can be skipped with pressing powerbutton. I checked sytem and it still showed "android 7 + EMUI 5" but built : BTV-W09C900B300
I think this is the one i "need" to be able to install the "HUAWEI MediaPad M3 8 Firmware %28BTV-W09 %2CC100B006%2C EMUI4.1%2BAndroid 6.0%29"
Problem is regardless which "update.app" i try to force install will get stuck at 5% and give me same error. I have ADB/Fastboot installed and tried some different things like flashing/unbricking it with "Huawei Multitool" where you can extract like boot.img or recovery.img and try to flash it.
Also getting an error. I can access eRecovery witout problems, the option to fix it by itself by wifi doesn`t work. I can´t access "normal" recovery and i think there is the problem (may got bricked while flashing Nougat?) I think its recovery problem, cause when i boot it up to the "half-installed" Android and go into setting "hard-reset" option i know it would boot up intoi recovery and would erease everything, while bootup it shows error "reset failed".
In fastbootmode i see bootloader: unlocked FRM: unlocked
I tried to install TWRP recovery with adb but get error: adb remote command not allowed
I downloaded like 15 different Android Versions 6+7 Emui 4.1+5 to try with force update but none worked, may i have to flash special version of recovery first?
I just want a normal version of android 6 or 7 i dont mind but at the moment with half working 7 "without" systemapps its a hardtime.
I hope someone can help me.
This isnt my first android device and im not a total noob i unlocked bootloader and flashed kernels on many other phones but with the W-09 where i did nothing special i dont get why "recovery got broken"
Thanks in advance
You haven't read other threads too well: more times people reported that the bootloader got locked after an update still declaring itself unlocked!
Second thing you have not found: the Nougat update consist of 2 packages and the second must be installed from TWRP.

thanks for your anwser, i read that so i also tried unlocking it "again" and it quotet it is also unlocked in adb. I also know that there are 2 packages. That you need TWRP i didnt know thanks so i am a bit smater now. I think i ll try "relock" and unlock it again might be the right way, thanks for the tip.

i cant unlock cause i dont have the code, on the huawei page i try do make an account and get the code by providing the necessary information.
I just uploaded a picture, i choose "before EMUI5" cause this is the only option i can choose "tablets". --> i choose "tablet wifi" , enter product model "BTV-W09" then the serialnumber i can see in setting: 28D6R17316XXXXXX but then i have the problem to input product id, it say i can get it through "Dialer" app (which i dont have in wifi model ) or the calculator. Problem is in my damaged installation there is no huawei calc, other calcs from store dont work (read that problem in other threats) I tried many apps from appstore to get a product ID but huawei site keeps saying wrong product ID =/
With the program DC Unlocker i am able to see a MEID i dont know if its the right one, i tried my luck with the Product ID Generator from Huawei but it doenst work. (device not supported)
It's very strange that it says bootloader unlocked if you have never unlocked...
And was very stupid to try to installl a beta release without before unlocking and taking a backup.
Exhange your device for a Nokia 3110!

yeah at this device i never touched bootloader, i didnt think it would become such a big deal , i didnt want unlocked bootloader or other recovery just newest android. Never had any problems with the "force update function" to come back to stock. I tried DC Unlocker but cant get further cause device need to get into manufature mode (thorugh dialer or calculator which i both dont have) i hope maybe i find one more way.
Did you ever find a fix
Did you ever find a way to fix this. I'm in the same situation. I even did a VPN on my router to give me a Hong Kong address for erecovery and that still didn't work. I have the exact same product. Like you I tried to various attempts to download a new recovery, but nothing works. Nice hardware, but some of the worst software/firmware I have ever dealt with since starting with the first release of Android on the HTC Hero.

I had mostly the same problem. I rolled back to 4.1 using the rollback and the actual 4.1 update.app. I think that puts you on C100 if I remember right. Tablet I have is C128 (USA) but no problem for this step. Get the Product ID from the calculator. Allow OEM unlock in the settings, then unlock it using the unlock code. Email yourself the unlock code because who knows if their website will even be functional next time. Alternatively you can extract the stock calculator from the update_data_usa.zip or whatever and try to use DC with 5.0. That second update zip does not install properly via the dload method, so a bunch of stock apps don't get installed. You can kind of hack it and flash it via TWRP but I didn't do it that way.
Or...you can use firmware finder to force an OTA from 4.1 right up to 5.0 (350), then take that last partial OTA to 351 after as well. The way to do that is via DNS in firmware finder. Find the Full OTA in firmware finder you want, send it to the updater by changing your DNS the way it tells you to, and when it does the OTA, everything will be properly installed basically the official way. Good as new. Flash TWRP to recovery2 and replace the erecovery. Keep the stock recovery as is. Install magisk. Golden.

Also, as far as the rollback, you need to do the first one (the C900 which is just a compatibility fix to allow rollback, previously used by beta testers I believe). Then you need to do the second one, the C100. If it is getting stuck, try downloading it again and be sure you don't have anything else in the /dload directory on either internal or the sd card. I had one on both at one point so maybe that happened to you. The C900 should be very quick but the C100 will slowly progress after 5% all the way around in several minutes.
When you get to updating back to 5.0, you can choose whichever region you want as long as it is a full OTA. C128 is USA and that's what I bought so that's what I picked. That gets you back in the right OTA update channel after that.
Hi guys,
I started as a novice and have learnt the hard way.
Has anyone tried rollback to EMUI 4.1 EU version on a US device (W09) and are there any problems I should be aware of?
I have had the exact same problem shared in this thread and have gone through the pain of finding a solution. My last resort is to rollback to 4.1 and restart the whole process.
@deV14nt: you suggested that when updating back to EMUI 5.0, I can choose the region even if my EMUI4.1 is EU version. How does this work?
Thanks in advance for your help.
(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.

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.

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

Edit 3: TL;DR: This is appears to be an S8 exclusive error, it's shown in the recovery:
"Product device tree not found, couldn't verify firmware" or something like that. For solutions, please look that up.
So, I bought a bootlooping S8 in the hopes of fixing it.
Since OEM and FRP lock are on, I went with installing Samsung firmware on it, as installing a custom recovery at this point is not possible.
The default recovery wouldn't work, so I wasn't able to know which firmware exactly to flash, because I couldn't find out which model exactly I have bought.
I do not know the carrier of the device either, but it should be from some german provider.
All of the firmwares I tried just bootlooped, but the recovery works again, except for ADB, which is quite unfortunate, and I have no idea why it fails, the device shows up when I'm in the recovery menu, but as soon as I activate ADB, it's gone from the list of connected devices.
Combination firmwares sometimes show some turning gears animations, but then crash with some, thought often memory related, pretty random crash issue.
Another problem I am now facing is that in the process of trying to find a working firmware I now upgraded the devices "binary level"? (forgot what exactly it was called) to 6, so I can't flash any older firmware or combination firmware than 6, since downgrading isn't allowed.
I received the device with either binary level 1 oder 2.
My theory is that I don't have the right firmware, since I keep seeing dm-verity and license errors...
I am happy to provide logs if necessary.
The goal is to have an unlocked bootloader/ custom recovery.
I literally am going INSANE over this FRP blocking me from flashing TWRP and being done with this in under 10 minutes, please help :c
PS: Some random info attached
Edit 1: With the IMEI code i found while opening the phone I now know my model number: SM-G950FZKADBT.
Any tips for finding the PDA code of the originally installed system? Or finding a matching firmware?
Is this even neccesary? Why do official firmwares not work for me? :c
Edit 2: Somewhat solution: I think the only way to recover this device would be to find it's firmware, which is just NOT to be found...
So, until a miracle happens I'm gonna keep reading "Firmware is not valid" errors in the log
Did you look in samfrew.com ? ? ? I just grabbed a fw from there.
