If there was any problem starting the rom and it was necessary to restore the stock rom. What is the procedure to do it? Asus only gives a ROM in zip format and only allows you to boot into bootloader mode (and from there to recovery mode and then fastboot)

So I had my tablet unlocked with twrp 2.4.4.1
I wanted to uptdate so I wipe the system and install OTA downloaded from asus website and flash it through SD card using TWRP
but I found out that my recovery partition had become stock recovery already
My question is.
With everything stock, can I just flash the recovery partition by doing the procedure below:
1. Go to bootloader
2. Fastboot option
3. on computer type in "fastboot flash recovery recovery.img"
Will this brick my tablet or destroy recovery that I never will able to update?
Im a person who feels safe with TWRP recovery so i can at least do something when something goes wrong.
Thanks
Is there a way to unroot this device?
Thanks in advance
You'll need a computer and TWRP recovery installed on your device.
Assuming that you have those prerequisites, simply flash the stock ROM in TWRP like you would a custom ROM (the .zip can be found here: http://forum.xda-developers.com/tmo.../lg-h901-stock-images-device-restore-t3241170)
Once you have that flashed, you can reboot into fastboot mode and install the stock recovery image using the "fastboot flash recovery recovery.img" command or by using a flashable .zip (the stock system images can be found here: http://forum.xda-developers.com/showpost.php?p=63604156&postcount=1)
That should do it.
Would need to lock the bootloader if returning it or selling it. Do that last tho
Hi, i've had my Z2 two years now and I've rooted, UB and installed roms on it many times but for some reason I can't get into recovery anymore. I flashed a different ROM a few months ago to try get it back to stock but since then, no recovery!
I've flashed the TWRP 1 click installer (only seems to work on laptop, on PC I get waiting for device but it says it worked on laptop) but still I can't get into a recovery to flash a custom rom.
Any ideas? How do I get recovery back? Please be a bit simple with me, i've googled it and just get overwhelmed by the info so figure I should ask and find out what actually applies to me..
Thanks.

If you have flashed a stock rom, you probably have locked your bootloader, try this (hope you have done a TA backup the first time you unlocked the BL...):
Download the Androplus kernel in development section, unzip it.
Then, download and use flashtool (install the drivers if need them) to unlock your BL again (BLU button).
Once you have unlocked it, disconnect the phone from the computer BUT DON'T BOOT IT.
Close and reopen flashtool, and select fastboot mode from flashtool and use the kernel flash option.
Select the boot.img you have unzipped from androplus (change the file extension to .img), and your are done.
Disconnect, reboot and you will be able to access the TWRP recovery from the kernel when you see the led, then flash a stock based custom ROM (with recovery), or CM one, try to have one of them downloaded and placed into your ext-sdcard.
PLEASE! My English is not good enough to explain this in a better way, if you don't are familiar with flashtool, fastboot mode or you don't understand any of the steps, wait for a better explanation or read a lot about it BEFORE doing nothing.
PS. Your internal data probably will be lost, make a copy of all your photos, docs, etc. You can relock your BL if you choose a stock based custom rom like eXistenZ, just restoring your TA backup after flashing it.
have u try flash via adb fastboot? it's easier when u have UB, try erase it first, "fastboot erase recovery" then flash the img (the latest twrp img is available on their site) "fastboot flash recovery recovery.img"
So I accidentally booted up my device after wiping my ROM (I was going to install CM) and now I can't get back into TWRP to even access my backup. When I hold vol up I go into Huawei's eRecovery, on vol down it goes into the bootloader. I can't seem to get into TWRP anymore and fastboot doesn't seem to have the option to boot into recovery like adb does.
Found the stock ROM that I needed here: http://forum.xda-developers.com/honor-5x/how-to/repository-honor-5x-file-depot-t3328288
can you
Code:
fastboot boot (your twrp.img)
?

I'm not sure what I did but I got into TWRP but after wiping everything from fastboot (because I thought I would try to flash a ROM from there) so now I don't have my backup. Now I'm looking for a lollipop ROM (preferably stock) because I never got this to marshmallow and CM13 isn't flashing.
@BryanTheStrange
you should wipe first, then flash the ROM and GApps from TWRP.
I think you can restore to stock using dload folder method. There is a thread disscussing it.
How can I lock the phone back after unlocking bootloader, rooting, installing Xposed?
Wipe installed custom ROM (System+data+cache+dalvik).
**Internal storage optional (You may have to flash TWRP again though).
Install MIUI recovery ROM pack through TWRP. Run MIUI initial setup. Reboot to fastboot and flash stock recovery, you can find stock recovery in MIUI forums. After that check for successful flash and successful system boot. Only then run the fastboot command to lock the bootloader :
fastboot oem lock
**Do not lock with TWRP. You'll hard brick your phone
***After flashing MIUI in TWRP flash lazyflasher or your device will be stuck
If you don't understand the complications in this method please ignore it, am sure there are some easier ways using MiFlash. Check MIUI forum for relocking and recovering to MIUI. If you wanna come back to the world of custom ROMs and Mods XDA is the place.

Thank You
BTW If you have the time could you write this more in steps like for a noob. If not it still kicks a$$ and thanks for reply
First you need to get rid of your current ROM and it's data. For that boot into TWRP and select wipe, in the list of partitions displayed select :
•System
•Data
•Cache
•Dalvikand confirm wipe. This step removes the ROM and data associated with it. Now the only thing you can access is TWRP and fastboot.
Also during wipe you can also select to wipe Internal Storage partition but after you do this you may lose TWRP also at the next boot. Now your phone can only boot into fastboot mode. So if you did wipe your internal storage also flash TWRP again from fastboot. If you ask how..:
•Download TWRP recovery from here
•Copy the downloaded file to any folder on your PC.
•Install ADB and fastboot drivers on your PC if you haven't.
•Reboot phone into fastboot mode(Power + Volume down) and connect to PC.
•Go to folder where your placed the TWRP image file.
•Open command prompt in that folder (Shift+right click mouse, open command window here)
•Type the following commands without the quotes :
" fastboot flash recovery twrp-3.2.1-0-mido.IMG "
•Now try rebooting into TWRP (Power + Volume Up). If you followed the steps right you should be able to.Remember this step is only if you decide to wipe internal storage also else it is completely not necessary.
OK now that you are left with a phone that only has TWRP we need a ROM to boot into, in your case you want a MIUI ROM. Download latest stable MIUI recovery ROM pack from MIUI website or just google if your having trouble finding it. For MIUI ROMs to successfully boot on a custom recovery you need to flash an additional zip called lazyflasher else your phone will be stuck at the MI logo. I'll attach the zip below. Okay so now since you have the required files copy them to your phone's internal storage.
Boot into TWRP and install the MIUI ROM zip first and the Lazyflasher zip after that. Reboot into system and phone should enter MIUI initial setup in some minutes(be patient MIUI initial boot can be long). Finish the setup.
Now you need to flash the latest stock recovery of your phone. I don't have it with me now so a simple google search will do the work. The procedure for flashing the recovery is the same as flashing TWRP which I have mentioned above. The only change you have do in the fastboot command line is the file name of your stock recovery.
After flashing check for successful boot, only then proceed with the relocking procedure as follows:
•Boot phone into fastboot mode
•Connect to PC
•Open Command prompt
•Type this fastboot command without the quotes :
" fastboot oem lock"•Once done reboot your phone.
Now you must have a relocked phone.
**Never relock your phone with any custom mods like custom recovery, custom ROM or even a MIUI which is rooted. Also be on 100% stock configuration before relocking device. Failing to do so will result in a hard brick.
