What bootloader do you have? 4.3 or 4.4?
I have a MotoG BoostMobile, and TWRP 2.6.3.3 would work only on 4.3, with 4.4 it freezes.
Make sure you go back to 4.3 bootloader and install, CMW 6.0.4.7. TWRP has touch issues..
Good luck!
hey mate no how I go to 4.3?? there Is no os In the phone

Get those 3 files, and rename mfastboot.zip to mfastboot.exe
Then set the phone to Download mode and in a command prompt (same dir as the 2 files) type: mfastboot flash motoboot motoboot.img
Be sure to use only mfastboot and not fastboot. This will flash the Android 4.3 bootloader.
Then use fastboot to install CWM: fastboot flash recovery recovery-clockwork-6.0.4.7-falcon.img
Reboot into recovery, and you should be able to use adb push or adb sideload to load a ROM of your choice (Preferably the latest CM11).
Good luck!
********** UPDATE ***************
I just tested CWM 6.0.4.7 and it does work with the 4.4 Bootloader!
So I don't think you need to revert to 4.3 bootloader if you are on 4.4 already!

oneplus 6 stuck in fastboot mood and fastboot boot twrp giving error

Hi i was trying to flash the oos on my device i did some mistake and the device now has no OS and it's stuck in fastboot and when i try to boot the twrp img it shows error that Failed to load/authenticate image and i can't install the rom please help
Well it's Solved i used the StockFirmware guide to unbrick the device but still no recovery was present but also i was able to access adb then so booted the twrp image file and just flashed the oos rom on slot b and it booted into the os. I am now using stock recovery and stock os.

Impossible to install custom rom zip with TWRP

Hi, earlier, I wanted to change the rom of my mi 5s. I've got an error 7 follow by "Failed to update system image" on twrp during the flash. I tried many things: edit the installation script, format all the data, update and downgrade TWRP, lock and unlock bootlander and finally perform a fastboot flash using mi flash and the last one worked. But I am not longer able to flash a custom rom without getting error 7 after the "Patching system image unconditionally" message. I've tested lineage, pixel experience, miui, even 8.1 rom but same result. I'm stuck with fastboot global miui 10 (oreo )
Btw, I think that after the error the partition are corrupted since I can't repair them with TWRP.
I don't know what I can do more.I think that i figured out that I am able to flash system.img file using fastboot but I can't flash zip rom using recovery.
As anyone encounter this ?

This usually happens when a partition is missed the way that TWRP doesn´t recognice the exact model and this error 7 is a kind of protection to avoid further mistake.
Some TWRP has in-built the option to fix system issue in advanced settings or then of try to flash a system image this option could appear.
Can you upload from any of the roms the updater script that is inside?
Also sometime you did a repartition? Or flashed some GSI?

Here is a script from pixel experience:
https://pastebin.com/DXgKrB8Z
I have the error "E1001: Failed to update system image" or "E2001: Failed to update vendor image" or just error 7 if I remove all the abort and assert.
I never did a repartition or flashed a GSI.

Just to be sure I guess you removed all the lines with getprop and not only the words.
Try first flashing persist image through fastboot.
If not flash the rom not through fastboot but using EDL mode and MiFlash tool, if you have unlocked bootloader you can send device through adb with: adb reboot edl or through fastboot with: fastboot oem edl

Yep I removed all the line
I managed to flash a full fastboot rom with mi flash and I think that during the process, a persist image was flashed. So i'm runing a stock miui. I even managed to flash Twrp and magisk. But I can't flash a rom through TWRP even after that :crying:

Some times causes different results flashing the fastboot full image through EDL mode (download mode) instead of through fastboot mode.
It could be the issue the TWRP version if there is other available.
And you could try deleting the recovery partition with fastboot erase recovery, then boot (don´t flash yet) to recovery using fastboot boot whateveriscalled.img, then in TWRP flash the TWRP image or the installer zip, then reboot for first time to TWRP and try again.

can't boot into twrp and I've soft-bricked my phone after updating to Android 12

Ok so i was trying to root my phone again after the Android 12 update. I messed it up and soft bricked my phone. fastboot works but fastboot roms haven't given me any luck and I'm now trying to install twrp so i can flash an older rom again but when i run fastboot boot twrp.img it just boots into fastboot again. am i really out of luck until twrp gets updated to Android 12? stock recovery works but isn't helpful. I've also had no luck with msmdownloadtool what can i do?
Since TWRP is not supported/works on A12. Your only option is to use MSM tool to get back. I would have suggested you try flash the stock boot.img from A12 you flashed, but that wont work since you tried the fastboot rom.
Had this before on my phone, and flashing the stock boot worked
