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.

Note 4 (SM-N910H) stuck in samsung logo (solved)

Hi all,
First of all sorry my English not that good,
and please read it to the end
few days ago I tried to downgrade from Lollipop 5.1.1 to Kitkat 4.4.4 which i found later it is something can't be done,
but back then processor failed and i get some things on Odin , it stops on sboot.bin and fail and my phone in download mode says : sw rev check fail device 2 binary 1
so as an android user i looked all arount the web and Xda forums and found a way to flash Kitkat with a way to avoid
sw rev check fail device 2 binary 1
which was to delete sboot.bin and modem and compress them to .tar again , and guys that was the dumbest thing i did,
My note won't start and says : FIrmware upgrade encountered an issue. please select recovery mode in kies and try again
so as usual I looked again and someone somewhere said "why don't you try PIT file"
so i tried and that work for me and WoW my note work again , and from then i I stopped all the Experiments at the poor Note 4.
but yesterday some App on my note (which require Root and I can't tell you what it is) do some weird stuff and reboot.
the devise work but this message appeared (com.google.process.gapps - unfortunately google play store has stopped) constantly, constantly and constantly ,and that is painful , so I backed up my files and wiped every thing and restart the devise but still getting the same message , so I tried flashing lollipop again but still getting the same error on download mode
sw rev check fail device 2 binary 1
so i used PIT file again but nothing worked
so you know the deal , I looked around and again someone somewhere said use CWM to deal with sw rev check fail device 2 binary 1
So i did , and get into recovery and I use every wipe option i did found,
and restart my note , and THIS IS THE END MY NOTE STUCK IN GALAXY NOTE 4 LOGO NO MATTER WHAT I DID
right now i am downloading Ukranian lollipop firmware but I don't think this will make a difference
Any help guys any solution to fix my phone , please i can't afford to pay to fix it
thank you in advance
UPDATE : My friend told my to root it again maybe it will work , but i just got the old recovery but still STUCK IN GALAXY NOTE 4 LOGO
So my device now working i just download this frimware
HERE
Ukranian one , and work like magic , I hope this thread work for someone else ,

If flashing the latest stock Samsung firmware back onto your device doesn't fix your problem. I would recommend taking it into a Samsung Service Center to see if they can fix it for you. If it's software based they will usually fix it for you free of charge.

Whatever happens to the phone, if the phone turns on, doesnt have any hardware issue it can be revived.
The universal method is flashing stock firmware through odin
Download your country's note 4 firmware from sammobile and flash it through odin
Works most of the time
For any more help pm m!

The same occurred for my LG G3 D855 which has erased its IMEI just for trying 'restore upgrade errors' in the LG mobile support tool. From that onwards I have firmly decided not to flash manually in any way except when official upgrades / uupdates are released via KIES or via OTA update.
Please do not flash by your own as it is always risky. It is not a PC where you can take out the affected hard disk and fix it in a working PC and backup the data.
To all manual flashing persons :
If your phone succeeds in manual flashing, donnot brain wash others to do the same. Not all persons always do R & D in android like you.

Thanks for the reply but the main problem is that any OTA that comes to note 4 i download them and the device says to restart to recovery to install the Update and i say yes but when it goes to recovery the recovery wont function well since it shows dm-verity error and supported API : 3 the update process fails to complete . My imei is as cool as always i havent had a problem with IMEI since i bought the phone

at least 10000 people have note 4 and none has had the problem ???? REALLY ?
seems like im pretty f***ed up

dear chappati , according to that video i need a physical thing which is called a BOX and a software called GC PRO because that guy had my problem and fixed it with a clicking , but im reasearching for 5 months and nothing comes out . i need information PLZ

Hi, i used to had that problem too, when i first flash a custom rom to my N910G i back up my stock rom.. everthing including EFS.. after that then i wipe everything like normal procedure when u flash a rom. till then 1 day i wanna go back to stock rom i accidentally ticked EFS while i wanna restore that stock rom back up and then i thought it was nothing serious until i flash stock rom with odin and when i boot into stock recovery that dm-verity message was shown, did so much research but no luck. my n910G was on a Singapore firmware, that time it had a update i just try my luck by downloading the latest SG firmware and then that message was gone! m now already on MM no problems like that anymore

I am not entirely sure what you are referring to by binaries and their versions. Problems with simcards usually indicate that something is wrong with your modem. This is usually solved by clean install. Backup all of your data! Go to sammobile and download latest firmware for your phone and your country. Then follow the instructions and flash it with ODIN. I hope it solves you problem

I think i screwed myself (Galaxy S8 Root)

Hey i couldnt find anything else so i hope this isnt a duplicate,
im somewhat of a noob when it comes to rooting but i know a little bit
Today i rooted my Galaxy s8 , everything whet smooth and without a problem,
but then for some reason i deactivated the OEM unlock and rebooted my phone.
Obviously that locked me out of my phone, after trying to flash my phone with the stock firmware that i downloded through samfirm
i got the error sw rev check fail bootloader device 5 binary 4 and i couldnt get that to work.
My next step was to try the Samsung smart switch emergency recovery, which failed.
I got the error that my device was not supported.
After that my S8 also stared showing me a blueish screen with the message : "An error has occurred while updating the device software....",
i can still access downlod mode tho
At this point i really dont know what to do and i should really be in bed because its 2 in the morning .
I really hope someone can help me out here, thanks in advance and a good night for now.

Device 5 binary 4 means you are flashing lower version of firmware than what is on your phone. Samsung will let you downgrade ( bootloader ) versions numbers.
You will need to flash a bootloader 5 or higher to fix.
Note: Don't relock oem in developer option.

Thanks for your reply!
That's what I found out too but I couldn't find a "higher" bootloader, I would have thought that if I download it through SamFirm it should have the proper BL
Do you have any recommendations on where to download the proper bootloader?
Yea that was a big f**k up haha
I just tried to get Poke Go to run but it wouldn't let me login because it detected that the Device was rooted I guess and after changing my device fingerprint and adding PokeGo to MagiskHide and still not being able to login I followed some FAQ blindly Wich recommended to turn off OEM unlock, and other things to hide the hardware site or the root, thinking about it again it should have been super obvious that this is a stupid idea, but you are always smarter afterwards right? Haha

Wow I feel stupid, I'm flashing the stock through Odin right now as I type this, I've downloaded 2 firmwares first one was a random one from online second one was the SamFirm , after realizing the first didnt work I must have deleted the samfirm variant by accident, I redownloaded it and now it's working , but thanks for replying!
