[REF] [ROOT] [RECOVERY] [BOOT LOADER] Metro PCS LG K7 LGMS330 [Guide For Dummies]

I have not been on this site since posting my guide, i do want to let any future people reading this know that, I am not a professional. everything in this guide is using stuff from other peoples threads.... this thread is just step by step directions on how i rooted (and installed TWRP on) MY lg k7 (MetroPCs). Also i had to root before i unlocked the boot loader. Which is not safe, you should probably unlock the boot loader before you root, but i couldn't figure out how to unlock it without root access.
I AM NOT RESPONSIBLE FOR ANY THING THAT HAPPENS TO YOUR DEVICE!
YOU AND ONLY YOU CAN BE HELD RESPONSIBLE​

C) click on the "new link" next to "Replace_Kingroot_With_SuperSU.zip"
D) extract the .zip so that the "MRW" folder is on your internal storage
(Easiest way is to download it on PC and open up your k7 in "my computer" and select internal storage and drag the MRW folder inside the .zip there)
E) go to google play and search "terminal emulator for android" or use this link if your reading this on your phone https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=en

H) type "su" without the quotations
(everything typed in the terminal is case sensative)
I) type "sh /sdcard/mrw/root.sh" without the quotations
J) you might see a few errors, that is fine
K) wait until it says finished
L) when SU opens, select "update" "install" or what ever pops up
M) when it asks to uninstall, uninstall it, it is not uninstalling SuperSU it is uninstalling Kingroot,
O) if 30 minutes pass and it is still uninstalling then exit the app and then reboot the phone
DO NOT STOP HERE ~ YOU HAVE TO UNLOCK THE BOOTLOADER, and OPTIONALLY FLASH TWRP
Step Nine: Unlocking The Bootloader
A) refer to step one and double check the OEM unlock is enabled and USB debugging is turned on
(If not then please enable them)
B) search quick boot on the google play store download the first app it should be a circle with a lightening bolt

E) if an add pops up close it with the ex in one of the corners
F) tap on the word boot loader
G) at the top of your phone you should see " * Welcome To Fast Boot Mode : "
H) now go to your SDK dir, in my case it is C:\Users\USER\Documents\SDK
I) hold shift, then right click on the "platform-tools" folder, then select "open command window here"
J) in the CMD window type "fastboot devices" - without quotations
(everything is case sensative)
K) then type "fastboot oem unlock" - without quotations
L) then type "fastboot getvar unlocked" if that doesn't work try "fastboot getvar" or "fastboot getvar unlock" to confirm if it is unlocked
(if non of the getvar commands work you did something wrong, and i wont be able to help you, but if you followed the tutorial you shouldn't have any issues as these are the exact steps i took)
M) then type "fastboot reboot"
LEAVE THE CMD OPEN OR YOU WILL HAVE TO REPEAT steps H-I
Step Ten: Flashing TWRP
A) go to http://forum.xda-developers.com/general/general/qa-metro-pcs-lg-k7-lgms330-t3331678 and click on the latest download for twrp for me it is BETA1
if the links on that page dont work then use the links here http://forum.xda-developers.com/showpost.php?p=66282525&postcount=42
B) extract the download into your SDK folder on your PC
C) in the sdk CMD window from Step nine
D) type "fastboot devices" - without qoutation
E) ~optional, HIGHLY RECOMENDED~
1)type fastboot "boot twrp-image-3.img" - this will boot up twrp WITHOUT flashing it, just so you can make sure everything is working right
in my case it was twrp-image-3.img check your twrp file name and replace fastboot boot twrp-image-3.img with
fastboot boot INSERT YOUR FILE NAME HERE.img
2)in twrp tap reboot>bootloader
F) when bootloader mode opens back up
G) type "fastboot flash twrp-image-3.img" or "fastboot boot INSERT FILE NAME HERE.img" depending on your file name
H) when finished flashing type "fastboot reboot"
Step eleven
A) follow instructions on step one
B) the reason you must do this is because when you flash TWRP it erases your entire phone and resets it
Congrats you have Successfully Rooted, Unlocked Your Bootloader, and Flashed TWRP, to your LG K7

Well done, my friend. Well done indeed.

is this ok with the gapps 5.1 instsall .zip for twrp install or should i use a different? also, do you have a suggested camera app? awesome thread btw. Nevermind simple twrp install fixed everything.

I have tribute 5 and can't access bootloader or install SuperSU.....always fails.
How can I get this to work?

Today backup important files you need!

Is this a real method BC everybody having problems rooting this device so I ask can u make a video and add screenshots
Sent from my LG-D800 using Tapatalk

I can confirm this method works. The only different thing i did was purchase Supersume pro from playstore. Worked like it said it would. The Ls675 is rootable. But no bootloader unlock or bootloader at all for that matter. Im running MS330 with TWRP full root and have twrp backups and fastboot flashable backups via flashfire....

Screen shots of root, flashfire backups, and device info

While it does work I can find no method using the buttons to get into twrp all the instructions I find for recovery fail so I can only boot back to it after the phone boots, thus it's worthless at this point. Also the command is fastboot flash recovery imgagename.img and you'll need to remove kingroot from administrators to uninstall.
Anyone else been able to boot directly into twrp from the off position?

Try to do the factory hard reset trick but say no at the second screen. I haven't tried it out yet but I've been reading around several sites and that's a possible solution

Just reboots. Think we're going to have to change something? Boot image? Kernel?

I'm no developer by any means but I have Linux and windows on my laptop. I'm familiar with kernel building on bunt and have the source code for MS330 on my laptop. I have a backup of my boot img as well. If you can get to fastboot u can probably flash my boot img if you want me to send it. I have recovery img as well which is twrp. Let me know if you have any ideas on what u need or i can do as far as possibly doing a fresh build kernel later tonight and getting a zImage out of it

Does anyone know a way to successfully root this phone? Not just recover?

Of other interest 5.1 is very dendent on Google apps and move app updates to the system via TB or Link2SD fails more than it succeeds, shows they moved but app inaccessible afterwards hence brick. Mine went down trying to integrate play services and reinstalling from adb didn't help. FYI if you relock the BL it'll lock the phone with a security error too. Moving play services causes unending error screens so you can't really see if it's done moving, but I waited a good 5 minutes before reboot. Issue on fails could have been the system not being r/w. Needless to say backup, backup, backup as I hadn't because I've never had a serious issue doing that and considered it a trivial task. Anyone had good success with integrating updates and cache? Anyone restored from twrp yet?

Can you figure out why we can't boot to recovery via hardware buttons? That's critical for tinkering and testing on the go since I always have my phone but not my laptop for booting into recovery with adb. Not sure exactly where to look, probably start with a search for the words "recovery" and "safe mode" for the buttons and "security error" in the boot.img files.

If your rooted u can dl a reboot recovery app on the play store I have one that works like a charm. But im gonna take a look through Linux at the kernel options using make menu_config and see if there's anything I can see in there.

Thanks again. For anyone that has a soft bricked LG K7 see this man! He brought my S#!? To life through teamveiwer. Thanks again. From my LG K7.

Maybe just my experience, but regarding step 10. I had to have the twrp image in SDK>platform tools, also when you get to fastboot flash twrp-image-3.img, I couldn't get it to work, until I typed it as fastboot flash recovery twrp-image-3.img. Hope this helps anyone else getting errors during this part. Thanks for the writeup.

No guide on How-to?
I'm actually trying to use your tool with my untouched Moto G2 I can't do any because there's no instruction on how to use your software.
I already made USB debugging on and I am expecting that your software is able to recognize my device but unfortunately nothing happens. I tried hitting ADB and Mfastboot drivers but nothing happens.

hello OP.
I have moto E4 plus XT1772 mediatek variant (nicklaus) and i unlock the bootloader with the command <fastboot oem unlock> so i don't have "unlock keys".
I saw on your post NO. 4: " NOTE: There is no need of bootloader unlock key while locking bootloader" but my device is from 2017 and i want to ask kindly if your tool can relock the bootloader of my device?
or can you suggest that i can use the command <fastboot oem lock>?
thanks in advance for your comments.

Thanks man, awesome job!

Hey guys. Thanks for the guide, I'm stuck however. I installed the latest global developer ROM in order to root and flash twrp, but there is no native option to root the ROM. What am I doing wrong? Bootloader is unlocked with xiaomi approval. Or is root China Rev ROM exclusive? If yes, the op should make that very clear, so that even dimwits like me understand it.

Hi there,
I did not use global ROM, true, don't know if possible with it.
Did you perform this step?
- Connect to WIFI
- Setting > Permissions > Root access
- Activate root access
The phone will then download a bunch of things and reboot.
After that you will be able to install TWRP and give it root access.
If not, tell me, I will update guide,
and you can reinstall Chinese ROM, to complete process, a matter of a few minutes.
Let me know

Thanks for your help! I already fixed in in the meantime, though. The permissions app only shows the root-button, if you are on the Chinese dev ROM. Which I wasn't (global one instead). Maybe you should add some extra weight to that in the guide. Other than that, it worked like a charm! Thanks buddy!
Edit: Sorry, didn't see that you pretty much already wrote all of that.

anyone else waiting more than two days for the request to be accepted?

Answer from TWRP is Success, but after reboot to recovery there is no TWRP, just MI logo all the time.

Have you downloaded the TWRP version for the 3 S? Not the Redmi 3?
I am not sure what are the differences here, but maybe the phone cannot boot if it is the wrong version.

Hmm, never seen that one,
Just to be sure, you did the following steps:
- Restart computer as per section: Windows 10 "Disable driver signature enforcement"
[...]
- Reboot to recovery, power off, power on "Vol. up" + "Power"
- Touch "Download" button (screen goes black)
- Plug-in USB cable
- Open Miflash tool... (this I know you did cause of the screen capture)
Do you have any devices identified as not properly installed in the Window peripherals?
Maybe try and install Android tools (also in the tuto) before and try to issue commands to your device.
Also, Googling "ping target failed xiaomi" I found that: http://en.miui.com/thread-354050-1-1.html
You might want to use older tool version.
Let us know

Thank you for your time.

Maybe you did something wrong cause most of the people here on XDA have no issue.
Try using an older ROM, or clean install... let us know!
By the way, this is just a guide to flashing,
Which I believe was useful for you cause you were able to change ROM.

Hey guys,
I really do not know what to do.
with redmi one - i did not have problems - ok only one time
now I tried to put new international rom on my redmi 3 in holiday. I really treid it for at least 10 hours now! no success. I think, i am stupid....
flash unlock with sms and tool "miflash_unlock-en-2.2.406.5" worked.
next step is to power off and turn on with power up and power button.
If I do this, the redmi device always goes to fastboot picture rabbit and does not react to anything.
At this point I could not do anything. I always waited until accu was empty (1day) and then try it again in some other way.
Is there some really good guide? I do not know what i am doing wrong.
thank you in advance.
my redmi 3s crashed yesterday and i have the same problem now.
see here:

Thanks for suggestion. But the reasons​ are
First thing is stock raw image of latest version is very difficult to find.
Second thing sometime asus flash tool stops responding. So you have to wait again for 30 minutes. Also it doesn't show progress sometimes.

Lenovo M10 Plus 3rd Gen Root Guide (TB125FU)

Notice! This process also completely resets your tablet! Backup all files and information.
This is just me documenting my process for rooting my tablet. I am not responsible for any damage or lost information due to the process changing, errors in execution, or mistakes in my documentation. Let me know of any errors, corrections, or updates that may need made.
Thank you to contributors to the thread linked below for the information provided that allowed me to create this more detailed root guide.
Custom Rom / rooting Options vor TB-125FU (Lenovo Tab M10 Plus 3rd Gen)
Hey everyone, I've been looking for options to Install a custom Rom or root since I bought the Tablet several month ago. It seems like there are some options for the Full Hd Version, but I have a hard time finding anything useful for the 125FU...
forum.xda-developers.com
This process was completed on Model: TB125FU
Follow documentation at your own risk!
First I updated my tablet until it was the newest system update available. For me that was version "TB125FU_S000118_220927_ROW"
Step 1 - Install tablet drivers on your computer
Download drivers folder and unzip
https://forum.xda-developers.com/attachments/android_adb_interface-zip.5741369/
Plug tablet into computer
Open Device Manager
You’ll see a line item labeled “ANDROID” with a yellow exclamation mark
Right click on it and select update drivers
Select Browse Computer and navigate to the unzipped driver folder
Make sure the Include Subfolders box is checked and select Next
This will install the drivers for the tablet
Step 2 - Unlock your tablet for usb debugging
Open settings on your tablet
Search for “build”
Click “Build Number”
Click the Build Number box seven times to unlock developer options
Close and reopen the settings app
Under System there is now a Developer options, open it
Toggle the selections for OEM Unlocking and USB debugging
Step 3 - Obtain boot.img
Download and install Lenovo LSMA
https://support.lenovo.com/us/en/downloads/ds101291-rescue-and-smart-assistant-lmsa
plug your tablet into the computer
run program, select rescue
check the allow USB debugging popup on your tablet
select tablet in the LSMA program and select the allow popups on your tablet
select Download when it shows the firmware for your tablet
DO NOT CLICK START RESCUE
close the program when it finishes downloading the ROM
The ROM will download to C:\ProgramData\RSA\Download\RomFiles
Make sure ROM folder name matches the current system update version on your tablet
Copy from the downloaded ROM folder “boot.img” to your tablet
Step 4 - Modify boot.img
Download Magisk apk from the official Github page
https://github.com/topjohnwu/Magisk/releases
install APK on your tablet
open Magisk
Select Install
Select “Select and Patch a File”
Navigate to the location you copied the boot.img file and select the file
Select “Let’s Go”
Wait for flashing lot to say “All done” indicating it modified the boot.img file
Transer modified file to your computer, for me it was called “magisk_patched-25200_rgIWh.img” I then renamed it “magisk_patched.img” to make future typing commands shorter
Step 5 - Unlock bootloader and flash modified boot.img
Download Minimal ADB and Fastboot Tools
I chose to download the portable version
https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790/
unzip folder
Place the modified .img file in this folder as well
Navigate to this folder, right click and launch a Command Prompt
Plug in your tablet to your computer if it isn’t already
Type “adb devices” to confirm your computer sees your tablet
Type “adb reboot bootloader” this should reboot your tablet into fastboot
Type “fastboot devices” to confirm the computer sees your tablet
Type “fastboot flashing unlock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to unlock bootloader.
Press the volume up button, It will say it was successful, wait a few seconds for the tablet to return to fastboot
Type “fastboot flash boot magisk_patched.img” and when you hit enter you should see a transferring status on your tablet (if you named your modified .img file something else, type that into the command instead)
When you see the transfer is complete type “fastboot reboot” which will restart the tablet.
The tablet should now be rooted which will completely reset the tablet. You will need to setup the tablet again and reinstall the Magisk app from the official Github. The Magisk App should now have superuser controls
You can relock the bootloader and return the tablet to factory image. IT WILL WIPE ALL DATA AGAIN!
To unroot you just reverse a couple steps.
Put the original boot.img (Make sure it is the boot.img of the same version ROM) in the Minimal ADB and Fastboot Tools folder on your computer
Navigate to this folder, right click, and launch a Command Prompt
Plug in the tablet to your computer
Type “adb reboot bootloader” this should reboot your tablet into fastboot
When the tablet reboots into fastboot type “fastboot flash boot boot.img”
When you see the transfer is complete type “fastboot flashing lock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to lock bootloader. Press the volume up button.
Type “fastboot reboot” which will restart the tablet
You tablet should now be back to normal.
***Note, if you relock the bootloader first it will not let you flash the original boot.img file. If you make that mistake as I did once you'll be able to manually startup recovery mode by first powering off the tablet by holding down the power button, then boot into recovery by holding the power button and the volume up button until the recovery screen appears. Then you can unlock the bootloader again.

Hello,
Please can you confirm that the model you tested is the same as
Lenovo Android TB125​ZAAJ0198SE​
The one above is a mediatek helio G80 4GB+64GB 2000*1200 resolution with Android 12 (bought some days ago, for sure it is M10 Plus 3rd Gen).
Thanks in advance.

Mine is: ZAAJ0401US
The process detailed above should still work on yours. Remember, you will be downloading the boot.img that Lenovo is recommending for your tablet, not using one I uploaded. So you will be rooting your specific file.
I doubt there would be differences between our ROM anyway but even if there were, it wouldn't effect you be because you are creating your own rooted .img.

Thanks for this guide. What system app did you uninstall after rooting?

I didn't remove any system apps when I rooted. I'm sure some are extra and can be removed safely.

Sorry, what is the reason for rooting then, when there are no custom roms yet?

Some apps require root access.

fastboot flash boot magisk_patched-25200_ofAPj.img
Sending 'boot_a' (98304 KB) OKAY [ 2.660s]
Writing 'boot_a' FAILED (remote: 'unknown command')
fastboot: error: Command failed
Click to expand...
Click to collapse
Now what? The bootloader is already unlocked.
EDIT: I had to use the volume keys to select "recovery mode" which opens a menu. From there I have to select "fastboot" (not "bootloader") which displays "fastbootd" (note the "d" on the end), then fastboot commands work.
BUT, after flashing the boot.img, it just powers off after the logo, no option to enter any kind of recovery, no USB connection. At most, if I hold Power for 15 seconds, then release and hold again, sometimes it turns on, and then if I hold VolUp, it boots to a recovery menu, but the only options are "try again" and "factory data reset". if I reset, it shows the animation for half a second, then shuts down.
On this menu it appears in "adb devices" as "unauthorized".
UPDATE: I was able to use Lenovo's "Recovery and Smart Assistant" tool to repair, but it has to be run on a Windows machine (will not connect in VirtualBox). It doesn't recognize the serial number, but by selecting "help finding serial" there's an option for manual entry of model number.
Choosing TB128FU and following the directions I was able to flash the stock firmware, but, the tool downloaded the wrong version. After flashing, the device claims the firmware isn't compatible with the hardware, and shuts down.
To fix this, I've had to find "TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_qpst" online. The tool downloads to C:\ProgramData\RSA\Downloads\RomFiles. You need to replace the contents of the folder in there (back it up!) with the contents of this, then it will flash a working firmware. (I think you can also use this to flash the patched boot.img, but I haven't tried). The only catch is, this is the Chinese ZIUI firmware, not the Global firmware it came with. It can be used in English, so I might keep it if I can't find the correct Global firmware.
https://wiki.postmarketos.org/wiki/Lenovo_Tab_M10_FHD_Plus_(lenovo_tbx606) PostMarketOS Wiki mentions that another file needs to be flashed any time you enter fastboot to prevent this brick. The article is for a different model, but probably the same applies.

I'm not sure why you got that error if the bootloader was unlocked. My patched .img file only failed like that when I failed to unlock the bootloader first.
Did you toggle the "OEM unlocking" in developer options on the tablet before trying to unlock the bootloader with command prompt commands?
When the bootloader is unlocked the tablet gives a warning message for a few seconds on every boot telling you that the bootloader is unlocked.

The "OEM unlocking" was grayed out saying the bootloader is already unlocked, and it does show the message at startup.
The problem might be that this is model TB128FU (not TB125FU) which is only sold in China, so it doesn't accept the same firmware. I don't know how the seller put the global firmware on it originally.

ok, i think i understand. Your tablet model number is different.
When going through the rooting process it downloaded the wrong version for your tablet without you realizing it so you patched and attempted to install the wrong version of ROM boot.img.
If so it means it is extra important to follow the line in step 3, "Make sure ROM folder name matches the current system update version on your tablet"
It is weird though that the Lenovo Rescue Tool didn't download the correct software for your tablet.

Does anybody know how to unlock bootloader for TB128XU? It is the same tablet but with Snapdragon SOC.
I am failing on unlock command. Both of these won't work :-(
fastboot oem unlock
FAILED (remote: 'unknown command')
fastboot: error: Command failed
fastboot flashing unlock
FAILED (remote: 'unknown command')
fastboot: error: Command failed

So everything worked great for me.
As a launcher I now use the Microsoft Launcher.
Nice interface and features.
The OTAs with Magisk Root also work great.

Thanks for this! I haven't rooted an Android device since Gingerbread (2.3) in 2010, so it was good to have a basic guide for the newer stuff.
One thing I noticed: Step 1 says to find the "Android" device in Device Manager and manually install the drivers. However, that device didn't appear in Device Manager for me until I booted into fastboot mode. So effectively I had to move step 1 to instead be later, immediately after this sentence:
Type “adb reboot bootloader” this should reboot your tablet into fastboot

Thank you to contributors to the thread linked below for the information provided that allowed me to create this more detailed root guide.
Custom Rom / rooting Options vor TB-125FU (Lenovo Tab M10 Plus 3rd Gen)
Hey everyone, I've been looking for options to Install a custom Rom or root since I bought the Tablet several month ago. It seems like there are some options for the Full Hd Version, but I have a hard time finding anything useful for the 125FU...
forum.xda-developers.com
This process was completed on Model: TB125FU
Follow documentation at your own risk!
First I updated my tablet until it was the newest system update available. For me that was version "TB125FU_S000118_220927_ROW"
Step 1 - Install tablet drivers on your computer
Download drivers folder and unzip
https://forum.xda-developers.com/attachments/android_adb_interface-zip.5741369/
Plug tablet into computer
Open Device Manager
You’ll see a line item labeled “ANDROID” with a yellow exclamation mark
Right click on it and select update drivers
Select Browse Computer and navigate to the unzipped driver folder
Make sure the Include Subfolders box is checked and select Next
This will install the drivers for the tablet
Step 2 - Unlock your tablet for usb debugging
Open settings on your tablet
Search for “build”
Click “Build Number”
Click the Build Number box seven times to unlock developer options
Close and reopen the settings app
Under System there is now a Developer options, open it
Toggle the selections for OEM Unlocking and USB debugging
Step 3 - Obtain boot.img
Download and install Lenovo LSMA
https://support.lenovo.com/us/en/downloads/ds101291-rescue-and-smart-assistant-lmsa
plug your tablet into the computer
run program, select rescue
check the allow USB debugging popup on your tablet
select tablet in the LSMA program and select the allow popups on your tablet
select Download when it shows the firmware for your tablet
DO NOT CLICK START RESCUE
close the program when it finishes downloading the ROM
The ROM will download to C:\ProgramData\RSA\Download\RomFiles
Make sure ROM folder name matches the current system update version on your tablet
Copy from the downloaded ROM folder “boot.img” to your tablet
Step 4 - Modify boot.img
Download Magisk apk from the official Github page
https://github.com/topjohnwu/Magisk/releases
install APK on your tablet
open Magisk
Select Install
Select “Select and Patch a File”
Navigate to the location you copied the boot.img file and select the file
Select “Let’s Go”
Wait for flashing lot to say “All done” indicating it modified the boot.img file
Transer modified file to your computer, for me it was called “magisk_patched-25200_rgIWh.img” I then renamed it “magisk_patched.img” to make future typing commands shorter
Step 5 - Unlock bootloader and flash modified boot.img
Download Minimal ADB and Fastboot Tools
I chose to download the portable version
https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790/
unzip folder
Place the modified .img file in this folder as well
Navigate to this folder, right click and launch a Command Prompt
Plug in your tablet to your computer if it isn’t already
Type “adb devices” to confirm your computer sees your tablet
Type “adb reboot bootloader” this should reboot your tablet into fastboot
Type “fastboot devices” to confirm the computer sees your tablet
Type “fastboot flashing unlock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to unlock bootloader.
Press the volume up button, It will say it was successful, wait a few seconds for the tablet to return to fastboot
Type “fastboot flash boot magisk_patched.img” and when you hit enter you should see a transferring status on your tablet (if you named your modified .img file something else, type that into the command instead)
When you see the transfer is complete type “fastboot reboot” which will restart the tablet.
The tablet should now be rooted which will completely reset the tablet. You will need to setup the tablet again and reinstall the Magisk app from the official Github. The Magisk App should now have superuser controls
You can relock the bootloader and return the tablet to factory image. IT WILL WIPE ALL DATA AGAIN!
To unroot you just reverse a couple steps.
Put the original boot.img (Make sure it is the boot.img of the same version ROM) in the Minimal ADB and Fastboot Tools folder on your computer
Navigate to this folder, right click, and launch a Command Prompt
Plug in the tablet to your computer
Type “adb reboot bootloader” this should reboot your tablet into fastboot
When the tablet reboots into fastboot type “fastboot flash boot boot.img”
When you see the transfer is complete type “fastboot flashing lock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to lock bootloader. Press the volume up button.
Type “fastboot reboot” which will restart the tablet
You tablet should now be back to normal.
***Note, if you relock the bootloader first it will not let you flash the original boot.img file. If you make that mistake as I did once you'll be able to manually startup recovery mode by first powering off the tablet by holding down the power button, then boot into recovery by holding the power button and the volume up button until the recovery screen appears. Then you can unlock the bootloader again.

By orange state I assume you are describing the unlocked bootloader warning screen.
Unfortunately I don't know of a way to get rid of that delay and warning screen from the boot process. It should not have any effect on your tablet other than just notifying you that the bootloader is unsecured. Rooting a tablet does this and creates a more vulnerable system state that the manufacturer wants to make sure you are aware of. The tablet should boot normally after the few second delay.
