Have you tried sending a command via the command prompt?
You should be able to do so, in fastboot mode.

Sounds like you have corrupted your boot file. If this is the case, its a simple fix. Extract the image from the attached file to the directory where you have fastboot installed, and then issue
Code:
fastboot flash boot razr_i_boot.img
Hope this helps.
fast boot?

How have you tried rooting your phone. Did you try flashing the zip file via recovery mode, or did you use the RAZRi_Root_Windows?
If you use tried flashing via recovery mode, then you will need to download the fastboot program. Try searching XDA for RAZRi_Root_Windows, or download the Android SDK.
If you tried using RAZRi_Root_Windows, then this includes fastboot, and the recovery image i included above.
Just open command prompt on your PC, and change the the directory that has the fastboot program located. Then, while your phones in boot mode, execute
Code:
fastboot flash boot razr_i_boot.img
thanks

[Q] Bricked! How to fix/get fastboot or bootloader with ADB

Hi mates,
My TF300t(unlocked) is bricked:crying: Im only able to go into TWRP(2.6.3) but i can't go into the bootloader(for using fastboot and co)
BTW, there is no Rom installed, so if i start the tablet (no matter if i press Power+Vol Down or not) i allays end in TWRP.
My TWRP is also "buggy". It has some problems, like: Unable to mount... / Unable to set emmc bootloader message.... / unable to find partition size for xyz.... So i cant use TWRP to flash/install something and factory resets didnt work.
There are a lot of good guides how to UNBrick the tf300t, but they all need fastboot. Does someone knows how i could Fix fastboot with ADB? ADB is working fine. Maybe i can use ADB to fix TWRP or even better Fastboot.
Sry for my bad english, please help my

Access via adb on twrp 2.4.4.0
Hi folks - time to activate an really old post
I do have also problems like manckosy in 2014:
The TF300t I have here has TWRP 2.4.4.0:
- Android booting is not possible
- it's not possible to mount SD-Card
- I don't have the permission to enter the tab via adb
Does anyone of you have an idea how I can get access with adb?
Thx a lot in advance!

Yes, I do! Hopefully you have "Minimal ADB and Fastboot" installed on your PC.
First of all, check whether you are able to reach fastboot protocol by pressing Power and Volume down together. Fastboot protocol should appear. That means now you have ADB access via USB and you will find further help here: https://forum.xda-developers.com/sho....php?t=2179759.

I Have a similar problem and the link above goes to a 404 page.
In my case, My Tablet boots directly to the TWRP splash screen, and freezes. I can get status and serial number via ADB, but that's all.
If I try to reboot (via ABD) I get no response.
The device appears on Windows10 devices list, but Fastboot can't see it (I get that "<waiting for device>" message). I guess that my TWRP is damaged somehow, only part of the ADB protocol is getting up.
That happened when I tried to clean up the cache and ended up messing it all up.
The Status on ADB says that the tablet is on recovery mode.
Is there a way of flashing TWRP with ADB only? Or it is bricked forever?
Thanks for any help

Please note if you cannot reach fastboot or recovery, your device is bricked for good!
Hello everyone, I urgently need help, brought this tablet to repair, hangs on the download logo, does not start any further, customers do not have a cable to connect to the computer, I have tried all possible ways to download recovery, fastboot, and indeed where Either it does not give out, a permanent download logo, tell me who knows what, maybe I'm doing it wrong

[Completed] Help! My Huawei G620S is stuck in "Fastboot & Rescue mode"

Hi,
While I was trying to export the original ROM from one Huawei G620S to another and something went wrong.
On the phone I was trying to backup the ROM, I was using ADB, as I used the command "fastboot flash recovery twrp.img" after the reboot my phone locks up in fastboot & rescue mode.
I cannot access Recovery mode by pressing volume up + power button, it always boots in fastboot & rescue mode.
ADB does not recognise the device anymore.
I'm stuck and in need of assistance (it was my wifes phone, so I'm a gonner...).
If you have a solution, please make the explanation easy as I am not an expert.
Thank you

Greetings and welcome to assist. Is this the twrp you were trying to flash ?

Yes I unlocked the bootloader with the code Huawei sent me.
No, I have no access to the Recovery mode anymore
I used twrp-2.8.7.0-trltexx
The device will only boot in fastboot & rescue mode.

Question [SOLVED] Asus Rog Phone 5 cannot communicate in fastboot mode

I've been using an Asus Rog Phone 5 for some time now and I really like it. Original WW version. Unlocked bootloader and installed magisk without major hurdles. I could carry over root by patching boot image in the inactive slot in case of a new firmware version.
I've just tried to upgrade from Magisk 23.0 to 24.1 and unfortunately it didn't installed itself into the boot image. I assumed I have to repatch the boot image using the new magisk and reflash. I extracted the boot image from the payload and patched it successfully in magisk app.
Now I have a problem accessing the phone in fastboot mode. I have no problem entering fastboot mode: first entering the bootloader and selecting fastboot mode. However I see no activity over the USB port and the phone is not recognized by the computer (either from windows or linux). If I boot into the system I can see the phone in adb mode. It responds and I can issue commands - for example boot the bootloader. But no signs of traffic in fastboot mode.
Am I missing something? How I may flash an image if I cannot access the phone in fastboot mode? Please let me know if you have any ideas how to solve this situation.
Thanks: Dw.
Don't enter Fastboot (Fastbootd) from the bootloader,Just boot into bootloader and try sending Fastboot commands from there. If you're connection & drivers are in good shape, you should be sorted...
use the side port to communicate with the phone in fastboot mode.

My honest suggestions : Stay away from OOS12 ( even base ). Besides, if u want to boot into EDL, just force power off the device totally. Then press and hold both Vol +- and plug the device into the computer with MSM stared, ur device will be in EDL ( ofc, u will have to install all necessary drivers beforehand )
