Please HELP!!! Accidentally flashed Twrp image to boot instead of recovery. - Android Q&A, Help & Troubleshooting

Hi,
I flashed TWRP recovery img file in boot instead of recovery. Now the boot fails and selecting recovery mode does not take me to TWRP recovery options. I am also unable to connect my phone via adb too. Is there any way to recover back my phone.
Phone - Surnia XT 1521.

Do you have any backup of the original boot.img?

No. Even if I plan to get it how do I flash it as adb does not detect my phone.

As per specification , your device have a Qualcomm chip onboard. Which means you have to use a Flash Tool for Qualcomm Chips like SP Flash tool (which is used for MTK Devices Of coarse).

Forgot to ask, also Check if Fastboot mode is still Accessible.
To do this , Press :【 Power Button + Vol Down 】

Fastboot mode is accessible but every option bring me to the same screen. Earlier selecting recovery mode would take me to TWRP recovery.
I tried installing Qualcomm Sanpdragon Snap Tool but it says that no port is available.

Solved
adb did not recognize my device but fastboot did.I installed the recovery using
fastboot flash recovery twrp-3.1.0-0-surnia.img

Recovery doesn't boot! Help!

So I did everything I could. None of the instructions on this forum help me, I am almost a complete newb in this.
I used this instruction: wiki.cyanogenmod.org/w/Install_CM_for_p3
To the part where you need to boot into recovery by holding power and volume up. Well, guess what, nothing happens when you hold power + volume up.
Please, could someone write a good step-by-step newb-friendly manual on how to get the Jelly Bean on this tab? I am seriously considering throwing this thing out of the window right now as I spent the whole evening trying to get this working with no results.
By the way, after doing all the manipulations with odin, now when the tab is loading and it shows the logo "samsung galaxy tab 10.1v", there is an image of an open lock in the bottom of the screen.

That means the bootloader is unlocked, the first step to install custom ROMs and recovery images.

Yes, with the P3, never could use POWER+VOL UP to boot into recovery (that combination can get out of stock recovery and into normal boot, which IS useful, since sometimes, one makes a mistake and stays stranded on a recovery bootloop.
Unfortunately, contrary to P4, there is no menu in the bootloader to boot into recovery.
You can however substitute that step 3 with this:
"From a terminal run adb reboot recovery"
[NOTE: its skipped in the tutorial, but for adb to function while in normal mode, you need to activate it, by going to Settings->Programmer Tools (or something like that, activate it, since its off by default and set the DEBUG USB connection on , or something - sorry, they changed the place in 4.1 and cannot give you the correct path)]
The device will then reboot into the Clockworkmod Recovery (assuming it has been correctly flashed); if not, repeat step 9 from section above.
Afterwards, you can either use adb or the Boot into Recovery menu option from the Shutdown dialog of ClockworkMod to boot into recovery.

I did adb reboot recovery, and it booted the stock recovery. Maybe I should use another recovery image? I used the one linked in the CM's instructions.
Ok, so basically what happens now is I flash recovery.tar.md5 through Odin, then it reboots in OS and I reboot it to recovery through terminal. The recovery says 'Android system recovery <3e>', so I assume it's the stock one?

Ok i figured out how to use fastboot command. Still I don't understand, which recovery.img should I flash? I don't have this file, at least not in an .img format, it's format is .tar.md5
So I guess my next question is, where can I get recovery in .img format?
OK, so I figured this out.
I downloaded the recovery.img for the Galaxy Tab 10.1 from the official CWM site (NOT 10.1v, cause they don't have it for this version. It worked fine).
then I loaded in bootloader, used ./fastboot boot <path to downloaded recovery.img>, I just dragged the img to terminal window.
Through this booted recovery, I flashed the CM rom and gapps (I did this without actually flashing the recovery, mind you).
After that, I used odin in windows again to flash their recovery.tar.md5, and now finally, when I use ./adb reboot recovery it starts up with CWM.
So yeah, thank you for your posts and thoughts, you helped me figure this out.

Yes, if you use "fastboot boot [recovery image]" instead of "fastboot flash recovery [recovery image]", you can boot to a custom recovery like CWM without flashing.

Fastboot only accepts .img files, Odin only accepts tar.md5 files; however, tar.md5 files are just archive files, if you rename the file to remove the .md5 extension and use a program like 7-zip which can read .tar files, you will find one or more .img files inside, which you can extract for use with fastboot.

One last thing: those instructions do not include adding root, as indeed you can use most of the functionality of Cyanogen without root (and possibly exposing your device to malware).
However many useful functions and apps DO require root; to check if you have root, either install this app, or do "adb shell" + "adb su", which should change the prompt from a $ to a #
For root the best way is probably to flash both zip files (ARM version) with CWM at this point (so you get the latest version); dont forget to hit the "Fix Permissions" CWM option afterwards to prevent any potential problems.

Hope you have backup of your personal data.
May be I can help, but few questions for you
1) which variant?
2) which rom you were on? which ics, which jb, or which cm?
3) why dont you people put model variant in signature? sometimes its useful for giving quick reply/solution.
I repaired normally through reflashing with kdz, but after flashing it does full wipe.
.....
Solved. Before post something, something MUST be tested. OK?
I am stuck on ics. Mo one way to reflash jelly bean, maybe unlocker bootloader can be the problem? I have try all

I literally ****ed up. No OS, No Recovery. Huawei Y6 II(CAM-L21). Help please :(

I literally ****ed up. No OS, No Recovery. My only hope is flashing from fastboot with my extracted images from update.app.
I just wanted to root my phone. I completely followed the step in this thread https://forum.xda-developers.com/android/general/rooting-huawei-y6-ii-cam-l21-t3501162 aside from just flashing TWRP 3.1.0.0 because TWRP 3.0.2.0 wont work for me. Well it was working for me and when I tried to flash the SuperSU.zip it says "unable to mount /data" so i'd do my research and to fix that i need to change file system to fat and format, then changed it back to ext4 and format. It fixed the issue but i was not aware that it will wipe my os. So I have no backup for ready. I'm down to no os but i have twrp. I wanted to make my own flashable zip rom that i extracted from update.app. The flashable zip that I worked does not working. The META-INF,system.img,boot.img then archived to zip file then flash it. I'm so ****ed up i tried to directly flash the images in TWRP. Flashed the boot.img to boot partition, and flash recovery.img to recovery partition. And when i tried to flash the system.img in oeminfo,boot, and recovery partition. The file size is big and it does not work that way. So in short i flashed the stock recovery.img over my TWRP. And that's ****ed up. My only hope is flashing the images via fastboot but my fastboot cant detect my device. I'm stuck at 2 boots only. The Huawei eRecovery ( i tried to download latest version and recovery via wifi but the package wont download) and Rescue Mode. Thankk youu in advance for helping me. I would appreciate it so lot!

I think it might have to do something in the twrp recovery. When my twrp recovery is working it shows my device and my laptop can recognize it. When I accidentally wipe my recovery it does not show anymore. One thing I found out that It recognize my device when I'm looking into device manager. It shows in Portable Device and something F:/

[Q] Go to Recovery Mode without hardware button.

Hi everyone.
I have this device, LENOVO TAB2 A7-20F and i want to install custom recovery on it. The problem is, my volume down button is broken. I successfully flashed the custom recovery to my device (TWRP, via fastboot, and flash_tool), but after flashing i cannot boot straightaway into recovery mode because of the broken volume down button.
So, is there any ways i can boot into recovery mode (from turned off device or fastboot mode) without need of volume down button.
Thanks in advance.
Here is my current attempts:
USING ADB REBOOT
I can use ADB to reboot to recovery using:
Code:
adb reboot recovery
But using ADB means I had to boot to android system. And I read somewhere that i need to boot to recovery straightaway after flashing TWRP. This method return a black screen, with opened-chest-android-robot and red triangle with exclamation mark on it.
Edit:
 @wittier suggesting using POWER + VOL UP combo when dead android screen shows up. It successfully bring me to stock recovery. I think it because I'm rebooting to system after flasing TWRP, and the recovery was flashed back to stock.
USING FASTBOOT BOOT
In the past I'm using fastboot boot command to boot using custom recovery image, so i give it a try.
Code:
fastboot boot recovery.img
It returns
Code:
downloading 'boot.img'...
OKAY [ 0.396s]

You were almost there already, though:
when you see the dead android on its back, hold the power button and tap Volume Up, then release. The key combo takes a little practice. So keep trying that a few times until you get to Recovery.

Just trying POWER + VOL UP combo, it works! But it load stock recovery (which I cannot use because of my broken button). I guess its because I have to boot to system after flashing recovery using fastboot (to use adb reboot recovery)
Is it true that one must not reboot to system after flashing TWRP because it will wiped and flashed back into stock recovery?
Is NRT can be used in fastboot mode or turned off device? I'm using linux and NRT need Windows.

Just trying POWER + VOL UP combo, it works! But it load stock recovery (which I cannot use because of my broken button). I guess its because I have to boot to system after flashing recovery using fastboot (to use adb reboot recovery)
Is it true that one must not reboot to system after flashing TWRP because it will wiped and flashed back into stock recovery?
Is NRT can be used in fastboot mode or turned off device? I'm using linux and NRT need Windows.
Thanks for the reply. Very appreciate it.

NRT can be used to flash / install TWRP as your recovery. I believe NRT can also be used to just Temporarily use TWRP as your recovery.
NRT can be used in fastboot mode or in power on mode on the phone. I don't know if the phone can be powered off when you want to use NRT. Doubt it.
Can't help you with Linux.
Once you are in recovery, can you flash a custom recovery, TWRP? (or in fastboot mode?)
I am no expert. So others will know more.
Have you tried reboot recovery app? It works for me

Also, you generally flash a custom recovery image from an application on PC with your device in download mode. Then you boot into it to flash a ROM. You should only have one recovery, stock or custom.
