you want to install back the stock recovery? or do you want a custom one?
if stock it's easy, if you want a custom one first you will need an unlocked bootloader then the custom recovery itself (compatible with your tab)
you have an unlocked bootloader??? what? how?
also try translating with google translate it's much better at asian languages (you koreean huh?)

그래서 , 이 순간에 당신은 당신의 장치 에 Lollipop 가 있습니까? 그리고 당신은 root 을 갖고 싶어 ?
또는 KitKat 로 다운 그레이드 싶어?

Yes, I have Lollpop. (rooted)
I no want KitKat.
I want custom recovery, but can this 'only' kitkat version. (sry english)
Therefore, I want stock recovery.
and english <-> korean translate(computer) is bed
I go to translate(understand) = very better

1. for stock recovery:
boot tablet in droidboot mode (PowerOff then PowerOn+VolDown)
on your PC issue the command: fastboot flash recovery recovery.img using the recovery.img from the stock rom
(i am assuming your droidboot is functional as you were asking for recovery)
2. if you cannot boot into droidboot mode you will need to restore the droidboot: extract on your PC from the OTA Lollipop package, the files bootx64.efi (it can be found in the esp.zip in \EFI\BOOT directory) and the droidboot.img file, then boot into dnx mode (PowerOff then PowerOn+VolUp+VolDown, screen should say "starting fastboot..."), at this moment issue in order these commands:
fastboot flash osloader bootx64.efi
fastboot boot droidboot.img and after it boots in droidboot mode enter:
fastboot flash fastboot droidboot.img
the bootx64.efi and droidboot.img are both from the OTA Lollipop package (you can find the OTA over the net, YT2-1050F_USR_S100017_1505261558_WW52_CN_otafull) or you can ask someone with Lollipop installed to give them from their system (bootx64.efi is on the ESP partition and droidboot.img can be dumped with a dd from the fastboot partition)
ps. there is no custom recovery at this moment (lollipop or kitkat) as there is no unlocked bootloader (one can flash whatever wants on the boot/fastboot/recovery partition but the images will be rejected at boot for not being signed)

Sorry, I find stock rom -> fail
I search YT2-1050F_USR_S100017_1505261558_WW52_CN_otafull, stock rom, other..
but, download -> ???.apk or close server or other.. nowhere rom
Where is stock rom?

1. do you need the recovery.img from the stock rom? if you have a valid droidboot(fastboot), ie if you get the droidboot menu when you start with (Pwr+VolDown) then the recovery.img can be found in the stock rom, check the all in one thread for 1050F stock rom (the recovery.img is the KitKat one, the OTA doesn't update that)
2. if you need bootx64.efi and droidboot.img meaning you cannot boot in droidboot(fastboot) mode (you are sure you cannot flash with fastboot) then the two files can be found in the OTA, search baidu for YT2-1050F_USR_S100017_1505261558_WW52_CN_otafull.zip, actually this is OTA for chinese package but i think it's safe to get/flash the bootx64.efi /droidboot.img from there (and only that)
Update: find all the needed files (from stock 1050F Lollipop ROM) here https://anonfiles.com/file/1025d77353f4395d090b07c88bcf156d
1. for stock recovery reflashing: boot tablet in droidboot mode (PowerOff then PowerOn+VolDown)
on your PC issue the command: fastboot flash recovery recovery.img
2. if you cannot boot into droidboot mode you will need to restore the droidboot first: boot into dnx mode (PowerOff then PowerOn+VolUp+VolDown, screen should say "starting fastboot..."), at this moment issue in order these commands:
fastboot flash osloader bootx64.efi
fastboot boot droidboot.img and after it finishes booting in droidboot mode (screen should display "waiting commands" in the bottom) enter:
fastboot flash fastboot droidboot.img

Fortunately, I did not run it.

System delete..

Hello! I have an P8Lite ALE-L21 unlocked and by mistake I delete the system.. Now I don't have OS to boot
What can I do now to have back?

Download the rom for your phone then install the rom using the recovery system op the phone.
If that doesn't work try flashing the rom through fastboot.

I tried both but it dosen't work
I don't find source with system.img

Use this http://forum.xda-developers.com/showthread.php?t=2433454&page=31 to extract the system.img
- Fastboot flash boot boot.img
- Fastboot flash recovery recovery.img
- Fastboot flash cust cust.img
- Fastboot flash system system.img
- Fastboot reboot
Use those commands and I hope it will be fixed.

Boot modify boot.img from fastboot

Hi,
i have a small question.
Does someone know why it is not possible to boot a modify boot.img from fastboot with
fastboot boot boot.img?
It stucks on LG logo.
zImage was nocht changed.
It must be somethink with fastboot, which does not allow to boot.
Any idea?
Big thanks

I need help with twrp ASAP please

I flashed 3.3.1-2 twrp and then installed a couple different roms to compare. Then I'm not quite sure what happened, I know I formatted and tried to install another, then I lost access to twrp. Even though it says I'm successful at flashing it, it won't boot into twrp or any recovery for that matter. What should I do? I've tried two different twrp's and neither will boot up. I've tried the .bat and volume+ and power, and I even tried with the fastboot boot twrp.img command.

What do you see exactly when you try to enter recovery mode? Stock recovery? Or fastboot? Which recovery have you tried? (provide links)

Glad to know I was able to help, it happens with me and this is how I fixed ?

Hello! Had the same problem and the procedure let me access recovery, yet everytime I reboot to system, the phone opens recovery instead.
I tried restoring a backup but rom is unstable and stuff keeps crashing. Any ideas?
EDIT: did a fastboot flash of .9 ROM and at got it back to work.

So I tried to go back to MIUI and it did it again, I did the default wipe and tried to install it. It got stuck in a bootloop and wouldn't go into TWRP again. Tried what you prescribed again, but that didn't work. I tried using the command (fastboot boot recovery.img) and it just shut off. It's clearly not flashing TWRP, but I have no idea why. I tried both 3.3.1-2 and 3.3.1-3, neither worked. I tried flashing more of the fastboot ROM images, but that did nothing either. Any suggestions? I'm having to use my old moto g5 until I get this fixed, so help ASAP would be amazing. Thanks in advance!

What MIUI version you have tried to go back?

2019 pro stuck in boot loop

Got this working with Lineage ok but decided to go back to stock. I downloaded the stock recovery rom from NV and set everything up. Inside the recovery bundle is a bat file. Usually I would flash all files manually but this time I used the bat file. It manged the first 3 or 4 commands then came up with error. The box is now stuck in a boot loop and I am unable to access over adb.
Can anyone please suggest a way around this.
Thanks
Here is the bat file
fastboot flash staging blob
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash dtb mdarcy.dtb.img
fastboot flash vbmeta vbmeta.img
fastboot oem lock (optional step: required for certain functionality)
fastboot reboot
EDIT:
Eventually managed to flash lineage zip again. Used USB keyboard to access recovery

may i ask, what kind of keyboard did u use?
thanks in advance
