[HOW TO][Unlocked Bootloaders]Install Fastboots, CWM, Tips & Ticks, and More

Now that the bootloader is unlocked, everyone is asking "WTF do I do now?". Well, here's a bit of help to get you started. I'm assuming you already have adb and fastboot setup and working -- if not, quit reading and get that taken care of. Also, I only run Linux...so I'll try to be transparent and only list the fastboot commands.
I assume that you're not a complete moron and can Google what you don't understand.
Don't use the stock\SDK fastboot binary for flashing /system.
An updated fastboot binary for Lin\Win\Mac can be found here on the Batakang FTP from our local, neighborhood Mattlgroff.
Linux -- Rename the file to moto-fastboot and add it to a directory in your $PATH -- Ubuntu\Debian users can just add it to ~/bin (enabled by default)
Windows -- Rename the file to moto-fastboot and put it somewhere handy...that's on you to decide.
ROOT\ADMINISTRATOR INFO
On Linux, you might have to run as root in order to run some of the fastboot commands. If your system uses sudo for root commands, typing "sudo -i" will bring up an interactive sudo shell so you don't have to type sudo over and over again. If your system uses su for root, well, you already know the command.
On Windows, you have to enable Administrator Privileges to be able to run some of the fastboot commands.
Linux Terminal Hints
~/ means your home directory -- example -- "gedit ~/Documents/file.txt" would open file.txt in gedit easier than /home/yourusername/Documents/file.txt
You can add a * to file names and directories to not type as much -- example -- "gedit ~/Doc*/file.txt" is the same as the command above, only shortened. If two files have similar names, like Documents and Downloads, then you have to type the name up until the firs different character then add *.
Use the command "../" to go up\back one directory. The command is stackable so "../../" would go back 2 directories and so forth and so on.
Use "cd" to change directories. Is an example really needed for this...
Proper Apps to Use
For zip file editing, use 7-zip on Windows and Archive Manager (file-roller) on Linux
For editing text files on Windows use Notepad++ or any text editor that has unix line breaks -- do not use default Notepad or Wordpad -- you've been warned. Use what ever you prefer on Linux. I prefer Gedit myself.
Basic Fastboot Command Syntax
fastboot flash "partition" "image" -- flashes partition image where partition is where to write to and image is the path to the image being written.
example -- fastboot flash system /path/to/system.img
fastboot -w -- does a factory reset; to expedite things, "-w" can be added to "fastboot flash system system.img -w"
fastboot continue -- continue with the boot process
fastboot devices -- list devices fastboot recoginzes
fastboot -s "device model number" -- set the device fastboot will write commands to; use "fastboot devices" to find model number
fastboot reboot bootloader -- reboot phone into fastboot mode (or restart fastboot mode while in fastboot); same as "adb reboot bootloader"
fastboot help -- list all of this & more
Command Info
Not all the fastboot commands work for us. Specifically, the "erase" commands. If a wipe command doesn't work, skip it. I'll mark them with a ! at the end if it might fail.
Install CWM Recovery by Epinter
Read Epinter's RAZR HD CWM Thread
Download the recovery image
On stock rom, navigate to /system/etc and rename install-recovery.sh to install-recovery.sh.bak
Reboot into fastboot -- use "adb reboot bootloader" from Terminal\Command Prompt
Wipe the existing recovery -- "fastboot erase recovery" !
Flash the recovery with "fastboot flash recovery cwmrecovery6028-xt925_20130219-epinter.img"
That's it, CWM is installed.

Easy Kernel Install
Download kernel-flash.zip in the attachments[/URL]
Open the zip
Replace the zips current boot.img and device_tree.bin from the fastboot of your choice
Install the zip with CWM
By default, kernel-flash.zip comes with Mex Retail kernel and devtree
Easy CWM Install
Download recovery-flash.zip in the attachments[/URL]
Install the zip with CWM
Not sure if its SS compatible, but it is CWM compatible (for the lazy Photon Q users).
Obtain root after installing a Stock Firmware
There are two choices for obtaining root after a stock flash. the closed source SuperSu by Chainfire & and the open source Superuser by Koush.
Download SuperSu zip from Chainfire (Closed Source)
Download Superuser from Koush (Open Source)
Download the one of the root zips above.
Reboot into CWM/TWRP -- adb reboot recovery
Locate and flash the zip (see below for an alternative way)
Reboot, that's it. Nice not having to run exploits\hacks\Linux just for root
Install Rom/Zip file with ADB + CWM
CWM has the awesome ability to install zip files without having to manually copy them to the phone first. All's necessary is a PC with working adb.
Reboot into recovery
Select "install zip from sideload"
On PC, type "adb sideload /path/to/zip" and press enter
The zip will now be copied to the phone's cache & install
Once installed, do any requirements you'd normally do like wipe caches, etc

I have done this numerous times and it still will not boot into recovery. I have read and followed epinter, yours, official cwm, and other various Google found instructions (none of them functionally different) and still the same result. It recognizes the phone, writes, completes, then if I reboot and select recovery it goes to the android with the open chest cover with the exclamation point....
Any ideas how I could be screwing this up?

Unless you're not rooted with an unlocked BL, there's really no reason why it shouldn't work?

I was rooted before unlocking... shouldn't it still be rooted?

Yes, I did. After fastboot, I followed the OP instructions to uninstalling the SS recovery and SS app. Boot into recovery and got the open android.

same here.

I have the same problem. I was able to flash cwm, uninstall the SS recovery, and uninstall the app. The first time I got the dead android symbol. I restored SS via Titanium Backup, reinstalled the SS recovery, and flashed cwm again. I tried rebooting into recovery and was able to get cwm working. As soon I uninstalled SS and rebooted, I got another dead android.

probably because were all on the XT926 if we were to revert back to XT925 then the recovery should work otherwise we will have to tweak the recovery to get it to work properly witht the XT926 software awesome thing is we can now free up the space that SS used for a rom slot however for noobs you might wana stick with SS once you hardbrick without anything to go back too it will be game over for your phone and then you have to con ATT for another

From Phone Off, Hold Power and Both Volumes.
If the phone is on, do the above and when the screen goes black, press them all again...I've been doing that for an hour now
I installed MR via fastboot and just now got it booting. I made the mistake of using the SDK fastboot to flash /system.

You won't lose root
And with an unlocked bootloader, all you gotta do is flash an updater zip with the su binary and app for Stock roms that don't have root
I'll link to a root zip in the op once I find one (or just make it; depends on how quick I find it in a search)

I had SS and was backed up, I booted up the "stock ROM" and was successful in unlocking the BL and flashing CWM. I made a new backup of the stock ROM and restored it with success in CWM. In the video it show he has MR , but im confused as to why.
Also, I cant seem to get rid of safestrap....how in the hell do you uninstall it???

[Q] Corrupt Bootloader

Please help!
I am currently trying to root my TF701t on Jellybean but I appear to have corrupted my bootloader. I can boot into the bootloader and do a system wipe and boot Andoid, but when I select the RCK option I end up with the Android image on its back.
I have downloaded CWM 6.0.4.6 and tried to apply the recovery.img file via Minimal ADB and Fastboot command prompt only to be greeted with "cannot load "recovery.img" Result too large".
To be clear the system boots normally and fuctions perfectly - this is strictly a bootloader issue which has been unlocked successfully.
Any help would be greatly appreciated and apologies in advance if either the solution to this has been posted elsewhere or I have not given you the information you require to help.
Many thanks,
East

You need to fastboot recovery from the bootloader.
When you reboot into the bootloader do not select RCK. RCK is the recovery, I don't think the default one can do anything, you just get the android on it's back.
So it should be reboot into bootloader and then don't touch your tablet.
Then from your pc fastboot flash recovery recovery.img

Make sure you are also on a 4.3 bootloader before you fastboot flash CWM 6.0.4.6.
The instructions above are correct
To flash a recovery you need to have the fastboot.exe file and cwm recovery.img file in the same folder.
Right click + shift on the folder they are in and choose open command prompt here
Boot into the Bootloader by either booting with the Power and Volume Down Buttons held down until you get the 3 icons or by typing the following into the command prompt.
Code:
adb reboot bootloader
Then type the following commands to flash the recovery image:
Code:
fastboot flash recovery recovery.img
fastboot reboot-bootloader
Start the recovery by making sure the RCK icon is highlighted (use volume down to move) and push volume up to select.

In Windows 7 you can just navigate to the folder with explorer and in the address bar type cmd and hit enter

Doh!

Thank You
Well.......this is very embarrassing.
I have rooted and installed custom roms on my last 3 phones including the my new Nexus 5 without any problems at all. I simply followed the instructions posted by the developers. At the same time I used to take the piss out of the other posters who raised queries because they hadn't followed the instructions. What do I do? Exactly that.
Please accept my apologies sbdags as it is your rom I am installing and thank you to You & Sleeepy2 for posting polite and prompt replys without having a go at me for not following your instructions.
Problem solved I am now rooted!
Thank you again.

No Command TWRP

Original: 7.1.1 Nougat
I unlocked Bootloader
I rooted
Installed TWRP
Wiped
Installed 8.1 rom
installed gapps
Installed Magisk 16
reboot to recovery -> No command
When i go back to bootloader and re install twrp via wugs, it works and loads. If I reboot into recovery again, even from twrp, it gives me the no command error.
Any solutions on how to permanently get twrp running

Yes. Stop using the toolkit.
You need to actually see the messages fastboot generates. To do that, you're going to need to use ADB and Fastboot directly, without the toolkit. Get Minimum ADB and Fastboot from the forums (search for it) and install it. Make sure USB debugging is enabled in settings, then open up a command prompt to the directory where you installed Minimum ADB & Fastboot. In that command prompt type the following commands.
"adb devices" - lists the connected devices. If you see a device, continue.
"adb reboot bootloader" - self explanatory. The equivalent of pressing power and volume down.
"fastboot flash recovery recovery.img" - self explanatory. Replace "recovery.img" with the actual name of the file.
"adb reboot recovery" - should take you directly to the recovery. "adb reboot bootloader" and the volume keys should also work as an alternative.

[RECOVERY][TB-X606F/TB-X606FA][UNOFFICIAL] TWRP 3.7.x for Lenovo Tab M10 FHD Plus

This version of TWRP works on the Lenovo TB-X606FA, TB-X606F and TB-X606X.
Warning: this TWRP will not work for any of the Tab M10 variants with Qualcomm SOCs. For the TB-X505F, see this thread. For the TB-X605F/L, see this thread.
Code:
#include <std_disclaimer.h>
/*
* We are not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at us for messing up your device, we will laugh at you.
*/
Encryption
This device was released with Android 9 using full disk encryption (FDE). But we now have Android 13 GSIs for this tablet - and Android 13 does not support FDE. Android 13 only supports file-based encryption (FBE).
If you are using a ROM/GSI that uses FBE, you must use the twrp with -fbe in the name. If you use the wrong one, twrp will not be able to decrypt the data partition.
If you don't know if you're using FBE or FDE, then run this command while Android is running: adb shell getprop ro.crypto.type. If it returns "block", then your device is FDE. If it returns "file", it's FBE.
Installation
With a stock ROM, it is recommended that you also install Magisk. This will ensure TWRP remains your default recovery.
If Windows 10/11 does not recognise your tablet in fastboot mode, then see post #2.
Step-by-step guide
download TWRP to your PC (see the Download section below)
download the latest magisk.apk to your SDcard or OTG device. Change the filetype from "apk" to "zip".
get a copy of the vbmeta.img file from the stock ROM. It should be located in one of the subdirectories of LMSA's c:\ProgramData\LMSA\Download\RomFiles directory (after you download it using the LMSA rescue (power-off mode). This is only required the first time you flash TWRP, or the first time after you re-flash the whole stock ROM.
if your bootloader is already unlocked, go to step 5. To unlock bootloader:
on tablet: go to Settings->System->About and press "Build number" 7 times to enable Developer Options.
on tablet: go to Settings->System->DeveloperOptions. Turn on: "OEM unlocking" and "USB debugging".
connect tablet to your computer. Tablet will ask for permission to "Allow USB debugging". Tick "always allow" and select "OK".
backup any files you want to keep to an external device (MicroSD/OTG/computer), because the next step will wipe all your photos, files, google account etc on the tablet.
Now unlock the bootloader:
Code:
adb reboot bootloader
fastboot flashing unlock
follow the instructions on the tablet, then reboot to Android.
note: if fastboot reports <waiting for device>, then you need to install the Mediatek USB drivers. Go to developer.android.com/studio/run/oem-usb, then find the link to Mediatek (MTK) and follow the installation instructions.
note: after unlocking, tablet will take a while to come back up - because it has to do a factory reset and encrypt data again.
flash the TWRP image:
Code:
adb reboot bootloader
fastboot flash recovery twrp_X606FA_11.img
fastboot --disable-verification flash vbmeta vbmeta.img
fastboot reboot recovery
backup the stock boot, system and vendor partitions in TWRP, if you don't have backups already
load Magisk:
In TWRP:
select "Install"
use "select storage" to locate device you stored magisk.zip on.
press the OK button
select the Magisk zip file
swipe to confirm Flash
when Magisk is finished, hit the "Reboot System" button
finished!
If you prefer to use button combos, rather than fastboot/ADB commands:
Vol Down + Power = fastboot mode
Vol Up + Vol Down + Power = recovery mode

Windows 10/11 does not recognise tablet in fastboot mode
If your tablet is recognised by ADB but not by fastboot in Windows, you might need to get the latest versions of fastboot and the Mediatek usb drivers.
1. use the latest fastboot version
Make sure you are using the latest version of fastboot. There were major changes to fastboot for Android 10.
If you are using PowerShell, make sure it's picking up the fastboot you expect: fastboot --version. If not, use ./fastboot from the directory with the executable.
2. update device drivers
Try the latest Mediatek (MTK) drivers from Install OEM USB drivers. When they are loaded, they appear in Device Manager as "Kedacom USB Device/Android ADB Interface".
If Windows complains that the drivers are unsigned and refuses to load them, then do this as Administrator in Windows:
bcdedit /set testsigning on
reboot Windows
install the drivers
bcdedit /set testsigning off
In Windows 11, you might also need to turn off Secure Boot in your PC's BIOS to get the bcdedit command to work.

So I have the ZA5W0097US, would you suggest this wouldn't work?

That looks like a TB_X606F. This TWRP might work. We won't know for sure until someone tries.
Remember, the screen will be blank when TWRP boots up. You'll just have to click the power button twice to wake it up. I'll try and fix that over the next few days.
If you decide to try this TWRP and it doesn't work, please let me know what happens. And when you're booted into Android, can you tell me what the results of these ADB commands are?
Code:
adb shell getprop ro.hardware
adb shell getprop ro.boot.hardware

New version is now available in the first post.
The blank screen issue is mostly fixed...mostly. The screen is still blank on boot when decrypting data, but then it wakes up. No need to press the power button anymore.

I just got my TB-X606F (it's actually finishing setup right now) and I'm going to try flashing this TWRP onto it. I *think* the only difference between the "F" and "FA" version is that the "FA" comes with some sort of Alexa capability.
Both adb commands output "mt8768".

TB-X606F/ZA5T0300US (the manual also says TB-X606X) confirmed TWRP and Magisk are working. Had a hell of a time with getting fastboot to work on my main machine so I used a virtual machine to do everything with fastboot.

Cool. I'll update the OP.
Maybe check you have the latest version of fastboot on your main machine. There were some major changes for Android 10.

Good call. My adb and fastboot were both way out of date.

I also have the TB-X606F and was able to get this working 100%. I thought it was going to wipe my system so I backed everything up beforehand, but no wipe. Just replaced recovery with TWRP and here I am. Thanks a ton, great to have another TWRP recovery device!

It will only wipe if you are unlocking the bootloader for the first time.
Thanks for the feedback.

You have to download Magisk-v21.4.zip and push it to /external_sd/.
If you did that, can you see your other files in /external_sd/ ?

Make sure you have the latest adb and fastboot from Google. There were some major changes to fastboot for Android 10.
Also make sure you have the latest USB drivers from Lenovo.

I have the latest adb and drivers. fastboot commands used to work.
I rebooted to bootloader and flashed thre patched boot image made with the canary version of magisk and got root.
I then reflashed twrp and vbmeta and things seem to be working. Except for fastboot commands whlle booted.

If you are using Windows 10, check that the "Android Bootloader Interface" driver is loaded in Device Manager when the tablet is in fastboot mode. See this post.
And when you say "except for fastboot commands while booted", do you mean "while the tablet is booted in fastboot mode" or "while the tablet is booted in twrp recovery or Android system"?

Latest ADB and drivers loaded.
Fastboot commands work while in fastboot mode, but do not work when booted to system any more.

That's ok. That's how it's supposed to work.
ADB only works when your device is in recovery or system. It won't work when you're in fastboot or EDL mode.
Fastboot only works when your device is in fastboot mode. It won't work when you're in EDL, recovery or system.
The fastboot utility is an interface to the Android bootloader. When your device is in fastboot mode, you can use this utility to configure (some of) the bootloader and partition images. That's about it. I'm oversimplifying again, but...once the bootloader has passed on execution to EDL or a kernel (recovery or system), the fastboot utility can't work because the bootloader process is no longer running.
Unhelpfully fastboot just displays the "waiting for device" message, rather than something like "waiting for device to enter fastboot mode".
I hope that helps explain what's going on.

Twrp is working as expected no issues I have found, except for the need to press the power button s few times after booting into recovery to get twrp screen.

Hello! I need a bit of help... I have a TB-606F, 4GB/64GB version
I'm stuck on step 5. I've unlocked the bootloader, flashing TWRP and vbmeta seems successful, but then I cannot reboot into recovery. Using the fastboot reboot command I get "fastboot: usage: unknown reboot target recovery". If I try to reboot using volume up + volume down + power it eventually boots to Android.
Any thoughts are much appreciated!
