Have you tried flashing the twrp 3.3.0-0.img file to the recovery ramdisk partition instead of using the zip file?

TWRP gives this error but it still works. The system partition can't be mounted in 10 as of yet. I haven't had a problem flashing anything though. It will give that error after every flash but so far everything works.

Fastboot the stock boot.img to remove twrp. Then try using twrp version 3.3.0-0. You will still throw mounting errors when you flash zips, but it will still work :good:

it worked thank you !
EDIT: twrp-3.3.0-0 still not working on my PIXEL 2XL TAIPEN

Just ignore the warning and pretend it doesn't exist, known issue, no effect on the installs.

I'm on the Android 10 version of pixel dust rom and I had to side load the rom, trwp, and magisk because I kept getting those errors. After the rom booted up, I booted back into twrp via the rom and everything was fine. Super weird, but everything worked ?.

On Android 10 the /system partition is locked at read only so it can't be mounted in TWRP as read write. To do a nandroid backup go to mount and select mount partitions as read only and check /system and /vendor then do the backup

Cannot mount system/cannot install rom

I just recently got an HTC one m7 that I've fully unlocked, s-off'd, and rooted and now when I try to install a Rom it fails or I should say it hangs on 1% never advancing. Furthest I've gotten is 7% on santod's nusensesixMAX Rom but it wouldn't finish. Is it my recovery? I'm on the latest TWRP. Anyone with any input please
Have you tried the No data Wipe RUU and see if it takes?
No I haven't
I would suggest doing that RUU. it is the one @dottat made where he says it will not wipe SD card that way you do not lose anything on the card. If it is a borked emmc chip and needs fixing, Dottat has some tricks up his sleeve that may work.
What's really weird is every time I boot into twrp I'm having issues with mounting system.

Update your twrp recovery to the latest. That is why system won't mount in recovery.

Nexus 5x in google logo. Cannot flash factory image

I wanted t oinstall Cm13 so booted into bootloader and unlocked it.
Then I installed TWRP 2.8.7.2 as my recovery. Then booted into recovery and flashed CM13 of 20/12.
It then started bootlooping the bootanimation. I waited for half an hour. The phone became heated and I switched it off.
I then decided to go back to stock 6.0.1 but I could flash using flash-all.sh. I then decided to flash manually each image and was able to flash boot, cache and recovery. But cannot flash system and vendor. Can someone help me i this.
Can anyone provide a twrp backup that I can use. (I didn't do a backup myself).
Please can someone help. Just bought the phone 2 days back. Please help.

There is no error. When I manually try to flash system or vendor there is the message sending 'vendor' or sending 'system' and gets stuck with that message. waited for almost half an hour and still no change.
When I booted into twrp, it says cannot mount /vendor and /system.
Edit : I use Linux by the way.

well, interesting. i've never experienced problem like you have... have you already tried to do it in windows? or install TWRP v2.8.7.0 and format partitions in that version and then reflash original ROM. but remember, with 2.8.7.0 you wont be able to flash CM13 (at least on my N5X i wasn't....)

Shouldn't you be using the latest twrp 2.8.7.2? Ive had issues flashing roms without using the latest version. You could also have issues with older versions of twrp and encryption. Id suggest wiping data from twrp and then flashing the factory image from bootloader.

Im in the exact same situation and my fastboot is broken. My PC isnt recognizing a device is attached anymore. No system or vendor mount in twrp
I think to be able to really do anything you need to get into bootloader and have fastboot recognize the device. Make sure the files from 6.01 are all correct and you're flashing in the right order. Follow the guide item #8 http://forum.xda-developers.com/nexus-5x/general/guides-how-to-guides-beginners-t3206930 If you can get the system.img and vendor.img flashed and then lock the bootloader it will wipe everything to factory, internal storage included. If you do that you must have stock recovery.img flashed as well. If downloading system.img hangs reboot and try it again.

I got it to work. I just had to change the USB port.
Why don't you try a different USB port or a different cable. Or even try on a different computer.

Can you give a try to nodded twrp and one more thing mount system before flashing any ROM.
Note: after decrypting if you want too boot into OOS you need to Flash SuperSU or otherwise the OOS will force encryption and that may create problem.

okay now after few trial and error method i have come to the conclusion that this happens only after unencrypting the device. after eunencrypting it wont boot any other roms except those which have been already backed up.
So,
can i flash roms on encrypted device? I mean i test a lot of roms and i change frequently.
I guess no, right?
Yes try with encryption as the ROMs doesn't require decrypting the device. Decrypted device is only required if you want to use multirom.
Good Luck.

how does modded recovery helps in this btw?
hope it works
OK So I am able to flash any rom with encrypted storage and latest modified twrp.
This is working for me right now but still haven't found solution why it wouldn't work on unencrypted storage.
Thank you.

Stuck with No ROM Installed

FOR SOLUTION READ POST:
[SIZE="5"]https://forum.xda-developers.com/showpost.php?p=71007646&postcount=6[/SIZE]
Long time silent reader here. I always find solutions for my problems in xda-devs, until now.
Hope you guys can help me once again..
So, yesterday I messed up my OP3 and wiped all partitions on my phone.
I've tried many steps, trying to flash a flashable stock rom (the one with boot.img and system img) in fastboot, result= installation succeed, but getting blackscreen on boot.
Installing full OOS rom from adb sideload using stock recovery, result= failed (* cannot read 'OnePlus3Oxygen_16_OTA_039_all_1701140133_03b794d8a8b44883.zip' *)
Installing full OOS rom from adb sideload using TWRP recovery, result= failed (* cannot read 'OnePlus3Oxygen_16_OTA_039_all_1701140133_03b794d8a8b44883.zip' *)
Copy the rom to my phone, and installing the zip with TWRP, result failed (error=7)

So twrp is working right?
Flash any rom say lineage os
Flash multirom by BitOBSessiOn
Flash multirom twrp
Flash oos as secondary rom
And then swap oos to primary rom
try with some other TWRP . May be v16 blu_spark
https://forum.xda-developers.com/devdb/project/?id=15934#downloads
Ye sideboard gives me issues aswell, push the zip and manually flash it In twrp: "adb push romzipname /sdcard/", the file is now ib the folder /sdcard/.

Then it's a twrp issue. I'm currently in Bluspark v16 so
Error 7 in TWRP AFAIK is an issue with using an incompatible recovery, try the latest one 3.0.4-1 I think it is from this forum.

I flash twrp bluspark as @Puddi_Puddin suggested and flashing Freedom OS. After that, I restore my data using my last Nandroid backup, then the bootloop comes again. Tried it several times using TWRP Bluspark with different ROMs, still no luck. So I suggest, there's nothing I can do to restoring my phone's data.
I read across the XDA forums and Oneplus forums that some people had similar issues for me, and they suspected something's wrong about corrupted partition, not because twrp version. And I also had tried flashing a few ROM in the past using the same TWRP 3.03 version without any problems. Strange.
Anyway, problems solved, my phone's up and running.
CASE CLOSED.
Thanks XDA

No ROM can be written to the device

I have this weird situation where I have working fastboot and recovery (TWRP 3.3.1.0) however I cannot write any roms to the device.
When I try to install a rom, everything seems to be working but then after the reboot I get stuck at the animation screen. When I reboot
back into TWRP, I see that the system partition is empty. It is as if TWRP thinks it is writing the files but they are not written. I don't know. I am really
confused. Can anybody help me with this?
Considering that TWRP is accessible, I am not counting this as a brick, yet.

But be careful, you will lose everything on the internal storage. So first back up things from twrp to pc.

That WORKS, Thanks!
