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.

LG G5 RS988 Removing RAC (rent a center) remote locking software

Hello,
I hope this post is not against the rules, but I believe I found out how to remove the Rent a Center tracking and locking software that I believe if from computrace that is installed on our devices. It acts like a root kit that automatically reinstalls itself and has a device administrator profile that you can not remove.
I think I figured out how to get rid of the RAC (rent a center) lock for good. The rac lock uses a system administrator profile along with a program called sec.abt that can not be removed or frozen. If you manage to uninstall it is just reinstalls itself. I was not able to find any information on how to remove this without using special hardware like an octopus box that costs hundreds of dollars.
I used LGUP with the uppercut modification (can be found here on XDA) along with the KDZ files from here https://lg-firmwares.com/lg-rs988-firmwares/
I was only able to find the USA RSS 11C firmware until I found the page linked above with the BPT 10D firmware. Whenever you flash the stock 11C USA firmware the RAC program comes back and once connected to the net will lock your device, however if you use LGUP and uppercut to flash the BPT 10D firmware using the upgrade option (refurbish will error out) I found that my device booted correctly and seemed to work, however I did not have any fastboot options and it said there were no updates available (you need fastboot to unlock the bootloader and the latest update grants that ability). I then reinstalled the USA 11C firmware and to my delight found that the RAC software and device administrator profile were gone.
I then checked for updates and it started download the latest update. I believe I will not have a problem unlocking the bootloader and rooting from this point on. I'll let you guys know if anything changes.
I'm only posting this because I have been sitting on a RAC locked phone for months that got locked over six months after I bought it used and really hope this can help someone else that got screwed over.

Bought my phone almost a year ago off ebay woke up yesterday to this RAC device lock. This worked for me thanks.

Well done..
This happened to me after buying a device off of ebay.. thankfully RAC lock happened within a couple of days and I was able to use the ebay return policy.. I'm gonna pass this on to the dude who sold it to me as he got conned as well.. I verified the original RAC owner with RAC.. the device was purchased in Puerto Rico..
Cheers!

I'm trying to do same with V20 (us996) , but there is only one firmware avaliable :| no older or newer firmwares

Nothing seemed to happened after I tried to flash back to stock using either file. Do you know what I might have done wrong?
EDIT: It works now. Not sure what happened buy after my 7th attempt, the flash went smoothly and I was able to follows inaudible101 instruction to remove RAC lock. Thanks for the help!

Hey bro, thanks for the input.
I know you're talking about LG G5 but Im exactly in the same situtation for an LG V20 us996(Unlocked version), I have kinda tried this but didnt work. Do you have any advice or any other thing to consider you could tell me so I try on my phne? I cant access the phone to activate usb debugging nor oem unlock
Thanks man!

If you go into safe mode you can turn on USB debug as well as enable OEM unlock. You can normally get into safe mode by holding power button like your going to shut it off only hold the power off till a screen pops up. Select turn on and phone will reboot into safe mode.

Samsung FRP Bypass

Hi, I'm a total noob on this but I don't know where to start to looking for an answer.
My girlfriend went on vacation (from Chile) to the united states, her mother gave her a cell phone (her cell phone at that moment) an almost new Samsung Galaxy S7 Edge (SM-G935P) from the Sprint Network.
Before returning to Chile the cell phone was unlocked (or so they said at Spring), so here in Chile she put her local carrier SIM but the cell phone never recognized the Sim Card.
So she hard reset the cell phone. Everything went well until he had to enter the original Gmail account for the cell phone. Her mother did not remember the password so after som trial and error, they manged to reset the Google Account. But now when I try to enter de Gmail and password give me this error: Unable to sign in device due to a recent password change. try again in 24 hours, I have waited more than 24 hours and still can't activate the account.
The cell phone is still showing at her known devices in her mother's Gmail account, and the password is correct but I can't by pass the Gmail Activation, I was reading that I can downgrade to a firmware that allowed me to by pass the Samsung FRP but I don't know wich firmware I can use.
Can someone plase guide me how can I activate this cell phone.
Thank you!

edit: You were right I apologize.
If you want to get your password then whoever knows the best information will need to tell google over the phone what that information was when initially set up...birthdays, time of creation,etc-when they ask and %100 will ask. If she/you don't know it..you may never get it back... but calling their --> Customer Support <-- is your best option.

For s7 edge Android 7.0
So I found a way to bypass Google frp on Android 7.0 for the s7 edge and couple other model, it's an old way but modified. First enter into the Google account login screen where it says verify your account. All you do is simply over load it with characters. Tyler a bunch misc letters and number until you have a long good string then begine select all copy paste do this until your phone seem like it going to freeze up. I did it until it took about 2-5 mins to go through. Doing this will send you to a screen says error something went wrong. Hit enternor continue and if you notice this time when it goes back to verify your account the screen should have a black background at the top where's your notifacatioons are . Repeat 2-3-4 times overloading it and getting the error message I'm not sure exactly how many time think it suffers a on phone and Android build I just know once isn't enough to do it so do it a fewbtime it'll take awhile to get the first error but after that you should have the character line copies and ready to paste. After a couple time hit back arrow on your phone clear to where it ask to select language or start screen and emergency call if done correctly it should now give you the accessibility menu also enter into the accessibility option and modify your set up. Mess with stuff a little be careful with setting up universal switches as you can really mess yourself up. At some point in time you should be able to get your notification menu to drop down and open. When this happens hit the little setting menu button long click it and it should shortcut you to system settings. Bypassing for temporarily. Set up your setting and movie your app permissions as much as possible. Now the trick is getting my Knox downloaded open and set up on your phone. Once you do this make sure you click on both my Knox and regular device administration for know to have some control and make sure you say yes for Knox to be able to reset wipe your phone . After device administration is set and that all done go to your pc or another phone tablet whatever and log into know online and you hold re your phone connected on it white a button that says wipe this phone. Click it make sure the phone has Wi-Fi or service connected and wait for phone to wipe this should reset frp and Google verification back to being a new phone. There ya go merry Christmas

Fцck no it ain't legit. Dude probably got baked & strung up that nonsense to laugh at folks who tried it. You could string up a petrabyte worth of miscellaneous characters so long that your phone would be permanently frozen... & you wouldn't get an error message to pop up, let alone one that would change your notification bar background color or whatever else he said

S7 & S7 Edge FRP [SOLVED]
Here's the real S7 & S7 Edge FRP bypass method..
Nougat 7.0+ will NOT work; You NEED to downgrade to Marshmallow. Links to Stock Firmware & FRP Removal files posted at the bottom.
- Download & extract the .zip file from my Google Drive below to your PC, then extract + run Odin
- Flash the boot.tar file that corresponds with your device (enables ADB)
- Once the device reboots to the Welcome page, run the Qualcomm.bat file (reboots to Download Mode & removes FRP Lock)
- Back in Download Mode, flash the [MM] Stock ROM (CSC_HOME keeps user data; CSC wipes user data)
You've now successfully kicked FRP's ass from the device. Congrats.
NOTICE:
- You will be able to upgrade back to Nougat 7.0 following successful FRP Removal
- I INTENTIONALLY LEFT A FEW STEPS OUT. It took me a solid week to finally crack this migraine of a phone. You WILL have to figure some parts out on your own just like I did. If you cant, why are you even here?

Flashing the boot image tar file causes bootloop. I believe that's also the eng boot file? For root? How do you solve bootloop? Also what marshmallow were you on before doing this?

I have not been able to fix it yet, it wasn't on MM it was Nougat.

There is Nougat boot files. Check xda here for Qualcomm s7 root. There's a boot file you need to flash before doing adb root.bat..this enables adb, But this also causes bootloop.

I've been reading a lot a topics here at XDA and I'm overly confused about which method or boot file to use.
I think this could be the one:

What do you think? although it is for another is for G935T no G935P

Just downgrade to marshmallow.. Try PJ2.. I used that. Flash the boot file provided, run Qualcomm.bat via adb.. Then flash again 6.0.1... If phone reboot after flash boot file, you'll have to be very fast, after phone boot to welcome screen, before it reboots, keep running the Qualcomm.bat till u see adb recognize device. It will say error. About phone storage. Just ignore. It has been unlocked

Starting to see how much of a headache this sh¡t was is? Took me a solid week to crack it.

I have a G935V that is stuck with FRP. I reset my password today and then happened to try to flash a new ROM (didnt know about FRP at the time).
Been trying this all day, but cant get the S7 & S7 Edge QUALCOMM.bat to run on the phone... a flashed back to MM and the Boot.rar pushes fine, but when the phone gets to the welcome screen its like my computer doesn't recognize the phone is connected. Any ideas?

This worked great on my VZW s7 (just had to get the right VZW firmware)...
@KjK89, you have to run the .bat file before the welcome screen. I basically kept running it over and over during boot and it took before th welcome screen.

Check my post about SAMSUNG S7 Nougat 7.0 frp remove

Thanks So much, the only thing that actually worked!

Anybody looking for a fix for Galaxy S7 and S7 Edge Factory Reset Protection Bypass needs to follow these steps and you'll get past this pesky protection.
The only step that wasn't clear was this:
- Flash the boot.tar file that corresponds with your device (enables ADB)
On Odin you have to choose the boot.tar file corresponding to your model number. This is done by selecting the BL button and only that one then in Odin click Start. This might be clear for veterans to flashing phones with new firmwares but it wasn't clear for me, being the n00b that I am. Thanks again. This worked great!

(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

US997 US Cellular/BRIGHTPOINT Bootloader Unlock Solution??

OK so I need some help...
When I originally purchased my LG G6 in June of 2019, I made sure it was a US997 model, but I ended up getting a BRIGHTPOINT version during my purchase. I went through the website to check the imei and the device ID and it gave me the not unlockable status.
After that, I went and decided to update the software manually to US99721e since it wouldn't OTA it and have been on that ever since. Now, I just recently tried while on the 21e software and I was given an unlock.bin code!
So if someone could help me out:
IF you're on a US997 BRIGHTPOINT G6:
-Download LG UP and UpperCut
-Download US997_21e_01_0211-UCL.kdz at lg-firmwares.com (this is the one I'm on, try this one first!)
-Once it's done, enable developer mode, adb debugging, and OEM unlock
-Go through the unlocking process
Please let me know what you find out!!

Is that only for us cellular?

I have a brightpoint LG G6, which I bought as the seller claimed it was an unlocked US997, failing to share it was a OEM phone. I don't understand how this works please can you clarify? I tried the unlocking process and I have to supply my phone information to LG. Their database says it is a brightwell phone and so they won't release the unlock. Are you saying that after installing this ROM I don't need the key from LG to unlock the bootloader?
I have installed Uppercut and LGUP (1.14 as newer versions don't seem to work). I downloaded the ROM and I have the LGUP loaded. It shows the phone using US99721a. I have 4 process options, Refurbish, Upgrade, FOTA upgrade or Phonesettings which is the one to use?

It works! At least I obtained an unlock.bin file from LG. I need to work out which is the best LG G6 US997 ROM and how to load it when my SD card doesn't work. Any help or pointers to useful information much appreciated. For anyone else trying this here is what I found. I downloaded the LG windows drivers and LGUP 1.14 (There are newer versions but these don't work with uppercut. I downloaded Uppercut from XDA website and then you run Uppercut not LGUP. This immediately caused my virus checked to block it as it contains a trojan. I didn't like that but googled to find others had the same issue. There seems to be a way to load the correct file to get LGUP to work directly and I would recommend researching that but I disabled the virus software and proceeded. I used the UPGRADE option in LGUP - you need to reboot your phone into download mode. To do so, disconnect USB cable then Power off the phone completely. Now hold Volume Up then plug in USB cable at the same time. Make sure that LGUP is NOT running when you connect the USB cable and start it once you are in download mode. It loads the ROM very quickly and takes a bit longer to reboot and then it needs time to upgrade android as you have a 6 months newer version of Android 8. Then follow direction on the LG unlock site https://developer.lge.com/resource/mobile/RetrieveBootloader.dev. You will need to install ADK https://developer.android.com/studio/releases/platform-tools unzip after you download. LG emailed my unlock code immediately.

Yes, I can confirm that it works with the US997 model now. I already was at version US99721e so I didn't have to jump through the hoops to load this version. I went through the steps to unlock the bootloader via the LG developer website and voila, got sent the unlock.bin file, too.
Now I am pretty sure that I tried that in past perhaps 1-2 years ago and it didn't work, so perhaps LG has secretly flipped a few bits in their database to allow unlocking for these not quite brand new devices.
I just applied the unlock.bin and got the "cannot check for corruption" warning on the boot screen. So this is working - fantastic!
Now have to restore my device from the LG Backup I made before and put on the SD card.

I had tried the unlock last year but I didn't retry before I updated so it may have worked anyway and the update of the ROM wasn't needed. I unlocked the phone and installed Sky Hawk recovery but when that starts it asks for a deception password and nothing I have tried works. I'm not sure if that is a real issue or I can continue safely with flashing a new ROM. Has anyone worked through this issue?

First, when you're in Adroid remove all screen lock mechanisms, you can re-enable it later.
Enable USB debugging, do adb reboot bootloader and fastboot flash recovery with this recovery instead (rel_o2):
https://forum.xda-developers.com/lg-g6/development/recovery-twrp-3-2-1-unofficial-fixes-t3722199
Do the button combo to launch recovery. If you're in recovery, first reformat /data (you have to enter "yes") to get rid of encrption and after that flash the anti-root removal tool mentioned in the post. Then reboot into recovery and then flash Magisk and/or your ROM of choice. Note that I have only used this with stock ROM and Magisk and not tried any custom ROMs, but the thread has plenty of people having also tried other ROMs.

How do you even know if you have a Brightpoint device?

I found out when I tried to unlock. http://mobile.developer.lge.com/

Thanks for the info. I'll dig into this once I know for sure that a version of Android 10 is available to load into the phone.
What I've been dealing with so far keeps asking for a 15 digit IMEI number. My phone only has a 14 digit value.
I pulled box (yes I kept it) and discovered that the IMEI is 15 digits. No idea why the value is the phone truncates the last digit. The site that checks IMEI numbers says that it is the platinum edition: US997PL. Gee, the box says that.
