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?)

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

MX4 bootloop brick after trying to update I firmware on A phone

SOLVED:
Hi,
I just bricked my MX4 after trying to update system image from 4.5.6 to 4.5.7 using this guide:
Extract I version update.zip
use sdat2img to create system image
dd system image to system partition on live phone and reboot.
I used the same procedure successfully before, x-updating 4.5.4A ti I then updating to 4.5.6I.
After updating to 4.5.7, the phone goes into an infinite loop of Meizu splash screen, Flyme balloon, reboot.
I can enter fastboot and official recovery, but can't flash any partition from fastboot.
The bootloader is still locked.
Does anyone have any advice for unbricking?
Update:
The bootloop suddenly froze up for long enough for me to use adb to push an update.zip to the "sdcard" root. Have now flashed 4.2.8A from recovery and booted the phone.
As I had to clear all data I will unlock bootloader before trying anything else.

Try do flash 4.2.8.2 with uboot.img modded (to reunlock bootloader) and reboot fastboot and tell me

Hi,
I managed to push 4.2.8.2 to sdcard then do a normal recovery reflash.
Have now successfully unlocked using the .apk method.
Now I need to find out if I can use that unlocked bootloader to flash recent "I" firmwares, or if I can only flash the unfinished cyanogen (would like to wait 'til that's a bit more polished before using it.
Anyway. Happy to have my phone back!

Maybe that newest 4.5.7I need a new kernel so you'll need to update to 4.5.7A before flashing system.img or you can flash directly 4.5.7I but you'll need to use fastboot flash boot boot.img
If a rom/firmware needs a specific kernel it'll bootloop if you don't flash it

Can I flash 4.5.7 I now that I have unlocked bootloader and custom recovery? If I understand the unlock threads correctly, I think I will relock the bootloader, or even brick if I try to flash the complete update.zip. Can I flash system and boot partitions using fastboot?

Fully BRICKED.
Now I FULLY bricked it (no more recovery).
Had successfully upgraded to 4.5.7 "I" and was installing super su for full root, before disabling update, but had forgotten that I still had official 4.2.8 rom as update.zip on "sdcard" root.
rebooted to TWRP recovery for full su install and recovery found the update.zip and flashed it.
Result: Bootloop, No recovery, locked fastboot, no possibility to flash anything.
Aaargh!

Where do I find a 4.2.8 recovery.img for this phone?
Maybe there's a possibility doing a fastboot boot recovery.img ???
NOPE:
[email protected]:/home/marius/Downloads# fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.662s]

Fixed with large hammer! Goodbye Meizu!

from the post I get that you are able to boot into twrp. then download the twrp flashable 6.0 zip and restore it.
here forum.xda-developers.com/moto-x-play/general/rom-xt1563-brasil-stock-6-0-twrp-t3272979

If you can access fastboot try flashing a clean 6.0 stock rom using rsdlite

Boot Loop - ZE550KL

Hello guys,
Sorry for my bad English
My phone just turned off even if the battery is almost full. When I turned it on its stuck in a boot loop. Sometimes it's goes to a screen where it would say process not responding. It's still on the stock ROM and recovery. I didn't try to root it or flash anything on it.
I tried some troubleshooting like flashing the firmware from the Asus website but it didn't work. Please help

Have you try flashing from Micro SD card in stock recovery?

Thank you for the reply bro. I already did and it's still not working.

To reset the phone in cases like this, one could also use fastboot.
Boot in fastboot mode by pressing VolumeUp button while switching on the phone, then connect the phone to a PC with a usb cable (you must have fastboot/adb drivers installed). You can now open a command prompt and use the commands:
Code:
fastboot erase cache
fastboot erase userdata
fastboot erase system
The second command erase all the user's data on the phone.
The last command erases the operating system and you must install the full firmware in zip format from the recovery afterward (with a microSD card or with a PC via ADB sideload).

you can install custom recovery?

I had a boot loop issue too. I could solve it by entering fastboot and trying using the defaut roms boot.img through fastboot. You can extract the boot.img from any firmware image file from the Asus site.
Code:
fastboot boot boot.img

After these commands, had to do a wipe data/factory reset prior to update from sd card (adb sideload not work at alll).
but no luck, keep boot looping...

This may result an error if you don't flash the right file,it depends on your firmware version. I have a file that works on lolipop (twrp.).

I had the same issue, as my device was on warranty period i took it to the service centre and they said the mother board is damaged

Im facing the same problem I installed a new ROM from SD card and it was successfully done but the phone is still stuck in boot loop and unfortunately my USB debugging is disabled my bootloader is locked and my phone is not rooted and it's in stock recovery can anyone please help me

heyy, even i deleted recovery by using
fastboot erase recovery
then, after that my phone stucked on fastboot mode..
and when i flash the recovery , it finished propery but there is nothing happen in my phone still stucked into fastboot mode..
when i press power+volume(-) only fastboot mode is opened..
what to do now??
how to reinstall bootloader (recovery or twrp)??
plz help guyzz//:crying::crying:

I face the same bootloop problem with my mother's cellphone. The bootloader is locked and USB debug is disabled.
I tried to flash stock img via adb sideload, and although it succeed, after factory reset in Recovery (and pull battery several time) I could finally get into the "setup wizard" of Android system.
However, the system will go into bootloop again when the wizard goes to "wifi" setup. The phone will not go into setup wizard again unless I do a factory reset (and battery pull) again...
It seems there are some hardware failure at Wifi component (Since I already erase all \data, \cache), and this failure caused reboot of the system...
Any idea?

Zenfone Selfie bootloop / unlock bootloader

Hi everybody
My Zenfone Selfie after a normal update (never modified) is in bootloop.
So I installed adb and fastboot and I flashed the twrp.
Then I tried in every way to flash a rom. I've tried both with official firmware and with various versions of cyanogenmod. Through fastboot and via adb sideload.
Even if seems to work, when I reboot I get the bootloop problem again.
As far as I can understand the problem it’s that I have the bootloader still locked. The official apk solution I guees it’s not applicable in my case. By fastboot oem unlock i get an error message (probably why i can not enable usb debug).
Do you know of other ways to unlock the bootloader or in general to flick my phone?
Thanks to everyone for the help
