If you do these steps exactly then your phone can enter the recovery normally and you can flash any stock or custom rom.
1- Download and install Minimal ADB and Fastboot from this link: https://www.androidfilehost.com/?fid=24521665358595410
2- Download and install Flashtool drivers from this link: http://doomlord.xperia-files.com/download.php?dlid=Rmxhc2h0b29sLWRyaXZlcnMtMS41LTIwMTQwMzE4
Skip Step 2 if you already installed Flashtool Drivers that install with Flashtool if you have installed it.
3- Download the latest twrp recovery from this link: https://dl.twrp.me/sirius/twrp-3.0.2-0-sirius.img.html
4- Move the twrp recovery that you have downloaded in step 3 to this Path C:\Program Files\Minimal ADB and Fastboot
5- Download this kernel from this link: https://drive.google.com/file/d/0Bwn7bAJ-USZjZzg0Q2I2RWlWa1U/view?pref=2&pli=1
6- Extract it then you will find boot.img take this file and move it too to this Path C:\Program Files\Minimal ADB and Fastboot
7- put your phone in fastboot mode by this way >> (Power off your phone completely then wait for 10 second then press and hold the volume up then connect your phone to the computer with usb cable while you are pressing and holding the volume up then the led will change it's color to blue.. that is the fastboot mode)
8- Now go to the Minimal ADB and Fastboot folder in that path (C:\Program Files\Minimal ADB and Fastboot) Press shift button from keyboard then press right click form mouse while pressing the shift button you will find an option [Open command window here] Press it.
9- In the command window write this command exactly: fastboot flash recovery twrp-3.0.2-0-sirius.img
10- Then write this command after it: fastboot flash boot boot.img
11- After it flashed successfully reboot your phone by writing this command: fastboot reboot then unplug the usb from the phone
12- when the phone reboot and the sony logo appears keep pressing the volume up and down until the twrp recovery opens
13- Done
I wish that i had helped you. if you want any thing just ask me and i will answer.

If you have your twrp 2.1 on pc, do fastboot install (see the twrp page for details) then adb push a rom to the prime and install it... you should be okay then....

When you plug the device into the pc, is it recovery or fastboot mode? Not sure it will show up if it is in a bootloop. Also if you are in recovery, you should be running adb from within the folder the exe file is in... basically open the folder, press and hold shift then rightclick and select open command prompt here then type adb devices and see what you get.

The adb commands won't work in fastboot... you need to use the fastboot commands.
From: http://www.teamw.in/project/twrp2/93
Put the attached file in your nvflashpack folder where you see the fastboot.exe, this way you don't need to type paths. In the same window press and hold shift, rightclick in the window and select open command prompt here. Make sure the prime is already in fastboot mode.... now, copy the command below and rightclick in the command window and select paste (avoids typing mistakes) press enter and with any luck you should be able to boot to twrp recovery...
You will need adb and fastboot for this method. Download the above file, check the md5, rename to twrp.img and put the file in the same directory as your fastboot binary (unless you have /platform-tools in PATH then you can flash from anywhere). Turn off your device and boot to fastboot (power on while holding volume down, then select the usb icon and hit volume up to confirm). The device will now be in fastboot mode. Plug the device into your computer. Run the following command via the command line:
fastboot -i 0x0b05 flash recovery twrp.img
If you use the attached file you don't need the modified bootloader, you will have an older version of twrp but the whole point is to get you running first...
After you do this, boot into recovery, connect the prime to the PC and with the rom in the same folder as adb.exe, open a command window like before. Type adb devices, you should see the prime... then do adb push /the name of your rom.zip/ sdcard/
For the name of the rom, I usually right click the file, go to properties and copy the name.. (no spelling mistakes) again, right click in command window and paste and be sure to put .zip at the end. This should take about 5 minutes to complete. Then in recovery, go to install and you should be able to flash the rom....

You need to rename the file see the red text above. I would download nvflash from here.... http://androidroot.mobi/t3_nvflash/ the windows zip file.... unzip it and from within the window get your command prompt.... make sure you have the twrp file I attached earlier in the same folder... then copy fastboot -i 0x0b05 flash recovery twrp.img and rightclick and paste into the command filed press enter..... it should install twrp....
now if I have misunderstood and you don't know how to get the prime into fastboot hold volume down and power, when you see the white text in the top left corner, press volume up then volume up to select fastboot of course the prime will be connected to the pc before this...
btw we were all noobs at one point... this is our school....

sent to Asus they want $220 to fix smh now trying to decide on paying or calling it a loss and buying the infinty.
If you can get to fastboot, then it's not a loss and it's recoverable.
Did you already send to Asus?

Please help

I am having a REAL BUGGER of a time with my Xiaomi Redmi Note 3 Pro (Snapdragon)!
1. It is not recognized by ADB in Fastboot mode.
2. I suspect it shipped wit a vendor ROM, and I'm trying to flash latest Official MIUI Global Dev (Marshmallow) ROM, but I keep getting errors in MI Flash (screenshot attached).
3. I want to Flash TWRP, BUT ADB isn't working, AND I cannot get to the download page for the cracked bootloader.
4. Seriously considering Resurrection Remix ROM, instead, but most of the above issues still apply.
I am NOT new to custom recoveries, flashing ROMS, ADB etc, BUT I am dealing with a new PC (Windows 10 Home, 64 bit, like my old (dead) laptop), and I'm new to this device.
PLEASE HELP. (Quite frustrated)
Fastboot won't recognize adb commands you have to use fastboot.
What you can try is booting into emergency download mode and using my flash to flash it from there. I think it's " adb reboot edl" while the device is on with USB debugging or using the mi updater app ( tap the three dots I think).
I think that this is not the correct section for your question, and i dont know the procedure that you follow but try to follow this procedure:
-Connect the phone at pc with USB cable
-Make sure that debug mode and OEM unlock was abilitate in dev settings
-Copy twrp.img in adb folder
-Shut down the phone and press power botton and - vol buttons for enter in fastboot mode
-Run this commands by terminal open in adb folder
fastboot devices
-If fastboot recognize correctly the device run this command
fastboot fash recovery nameoftwrp.img
-After reboot the device with this command
fastboot reboot
When the phone reboot press immediatily vol + for enter in twrp
Good luck
GOT IT! FINALLY!
-I finally got ADB to connect, and was able to enter EDL through ADB.
-Re-downloaded ROM from web.
-Re-extracted.
-FLASHED SUCCESSFULLY!
-SETUP COMPLETED SUCCESSFULLY!
-YAY!
(I think the original download was corrupted, somehow.)

Can't access recovery after 7.0

Hey there!
so, I just upgraded my z5c from MM CyanogenMod to this nougat ROM > [ROM][7.0][Stock][.33][3.7 b7][Deodex][DeBloat][Font][Stereo][Vulkan™] Xperia Loop™
Before the update I could enter TWRP without any problems.
Now, everytime I try to boot into recovery the phone simply reboots...
Things I've tried:
• Typed "adb reboot recovery" on CM
• Downloaded TWRP App to re-flash and click on "recovery reboot"
• Power up phone holding Volume Down
The phone is rooted with SuperSU.
The main reason I wanted to regain access to recovery is to re-root the phone with Magisk.
Thanks for your time.
1. install fastboot and fastboot drivers on your pc (if you don't have them obviously)
2. plug the phone into the pc using the usb cable while holding the volume + button (this way you will skip the adb part)
3. wait for the notification light to go blue
4. go into the fastboot directory
5. download the twrp "recovery.img" file and put it into the fastboot directory
6. hold shift while right-clicking into the directory where fastboot is
7. use the option to open a cmd into the directory
8. type in "fastboot boot recovery.img"
if your phone's fastboot drivers don't have signature (like it happened to me) download Zadig and create a signature for the driver
Hope this helps... i had the same problem and solved by doing this

Normal TWRP has known problems...
You can try flashing Squid TWRP (https://forum.xda-developers.com/mo...wrp-squid-twrp-recovery-moto-e-lte-t3137649): is a unbloated and optimized twrp for our device.
This situation has appened to me and i resolved by installing that TWRP.

From the video you posted before i assuming you have already installed motorola driver and fastboot or mfastboot.
Here are the steps:
0- Download SQUID TWRP and place it in e.g. C:\ (last version is twrp-surnia-3.2.1-r1.img);
1- Shut down your phone;
2- Press Power Button + Vol Up until you see bootloader screen;
3- Now connect your phone to PC;
4- On PC, open a commad window pront (Start -> "cmd" on research bar, then enter);
5- Cmd prompt;
6- Type "fastboot devices". It should show a serial number: PC has recognized your device;
8- Then type "fastboot flash recovery C:\twrp-surnia-3.2.1-r1.img" last parameter is the path where you placed recovery so change it if you have choosen another path;
9- Wait for 3-4 seconds until the prompt shows something similar to "complete" or "success";
10- Type "fastboot poweroff" and your device shuts down.
Now you have installed Twrp Recovery, if you want access it, repeat steps 1-2 and select recovery from bootloader menu.
If you want install a custom rom i suggest SlimRoms : follow the instructions to download and install this rom.
