Well, it really depends on your edit.

I have mounted system.img.ext4 and removed some files from it then i have recreated the image and flashed to phone but i receive this error when the phone starts.

re install the firmware or install a new one....that should serve the purpose

the phone is working when i flash the original fw but i want my modded system.img.ext4
with the modified system i receive this:
Not need checksum confirmation already executed!!... (this is normal )
then:
E:failed to mount /system (invalid argument)

@grigoreee - I have the same problem like You with system...
Do You found any solution?
I think that replace boot.img from this thread:
Code:
http://forum.xda-developers.com/showthread.php?t=1719699
end's in the same way

How did u guys extract the system.img.ext4?
using dd?

I use this method:
Code:

(in mini2 system is mount with the same parameters as described above)

No solution for this error?
I still receive the same error......

try to format /system partion from cwm in mount and storage

Stuck at YU logo

1) Accidentally wiped all data including Internal Storage
2) Twrp 3.0 is working, but can't able to install any rom, Getting E:failed to mount / cache (Invalid argument) etc etc..
3)Getting "NO OS Installed" message in TWRP &- Internal Storage size is 0 (TWRP)
4) Followed Steps to flash factory image (WINDOWS)
Download the factory image fastboot package
Extract the contents of the fastboot package into a folder.
Download this flashing tools package
Extract the contents of the flashing tools zip into the same folder
To make sure, check that system.img, boot.img etc files are in the same folder as flash-all.bat, fastboot.exe etc
Connect your phone in fastboot mode, steps for which are : -
a. Power off your phone
b. Press and hold the Volume Up key
c. With the Volume Up key, connect the phone to your PC/Laptop with USB cable
d. You can let go off the Volume Up key when Fastboot Mode is displayed on the screen
Run flash-all.bat by double clicking on it.
A command window will open and flashing procedure will start
DO NOT disconnect the device during flashing procedure
The command window will close after the flashing process is over.
Disconnect the USB cable, and boot the phone normally by long pressing the Power button
But getting this error while flashing: http://imgur.com/g3NozUJ
After reboot,phone is stuck at YU logo..

Yuphoria stuck at YU Logo.
I had got notification for the OTA Cyanogen 12.1 Update and I had updated it. But even after reboot, the same 12.1 Update-notification would still appear again.
Later, I switched off Yuphoria to take out the External-SD-Card for data-transfer. Then when I switched on the Yuphoria, this Yu-Logo Boot-Loop Problem has started.
Now, My Yuphoria is Stuck at Yu-Logo on boot... and showing 'cannot mount partitions' errors when I boot custom-recovery twrp.
I have unlocked the bootloader.
From what I read online, I guess the memory partition-tables have got corrupted.... Now how can we solve this corrupted memory problem ?
I read about fastboot-flashing database.rfs or dbdata.rfs in some xda-developers Threads.
-----------------------------------------
I tried flash-all.bat with latest Cyanogen Official 12.1 ROM signed-fastboot.zip file... but still stuck at Yu-Logo on boot....
I fastboot boot trwp 2.6 custom-recovery.img and installed Cyanogen 12.1 ROM signed.zip file from external-sd card. But trwp says cannot mount partitions '/data', '/system', '/cache' etc...
---------------------------------------
I ran the command e2fsck /dev/block/bootdevice/by-name/system in terminal.
Then this message came : 'superblock has an invalid journal (inode 8) ext4'
I entered yes for correction multiple times and the process completed....
But still stuck at YU Logo on reboot.... Please Help.
-----------------------------------
I erased persist, then flashed persist.img.
Then I booted into twrp recovery, and adb sideload cm-12.1-YPG4PAS8A8-lettuce-signed.zip
The sideload started and then stopped with error : failed to unmount /cache ; failed to unmount /data ;
-----------------------------------
I boot into twrp 2.8.7.2 from fastboot-mode using command : sudo fastboot -i 0x2a96 boot twrp.img
Selected Wipe → advanced wipe → selected data :
It shows :
Mount Point : /data , File system : ext4 , Present: Yes, Removable: No, Size:0MB, Used: 0MB, Free 0MB, Backup Size: 0MB
Then I tapped on change/repair file system → change file system → EXT4 → Swiped IT...
Error : Format Failed.
E: Unknown MTP message type: 1
Failed to unmount '/data' (Invalid argument)
Error changing file system.
Updating Partition details.......
Failed to unmount '/system', '/data', '/cache' (Invalid arguments)
....done
Unable to mount storage.
After 'Change File System' Failed, I tried 'Repair File System' and 'Resize File System' also... all Failed similarly....
Only TWRP 2.8.7.2 and lower versions boots successfully in my Yuphoria.
TWRP 3.0.0 will not boot successfully. The TWRP logo will appear and then show command errors, and the phone will restart.
Please help me reinstall OS in my softbricked Yuphoria.

Exact same problem for me... someone please help..

I too have been stuck up with the same problem, but in Yu Yureka...Brothers, Don't we really have a solution for this issue?!?!?...Please do something dear nerds lot of thanks!!

same prblm
anyone got solution for this ??

Exact problem.........
I ve gave it micromax service center, they asked 400 and began their work. after some time the man came out and sad, this is a board problem, you have to change the board. My friend is an embedded service engineer. He is saying its just a soft brick and the device is perfectly working. Those knowledgeless idiots dont want to find solution for this, the simply trying to change the board. Friends the problem we have is 100% a software issue, pls dont fall in their trap............

Same issue
Guys anyone got the solution ? Please help ...

Anybody got solutions, please respond

Same here
I tried everything but nothing seems to work. Someone help....

Seems to be Soft-Brick Software issue....
TWRP Recovery is not able to mount the /system , /cache and /data partitions...
but inside TWRP Recovery FileManager , we can open and browse all partiton files and system folders/files in /dev directory....
Also the TWRP Terminal shell can be used to run e2fsck and mke2fs commands...
So I think the /system, /cache and /data , and other corrupted android partitions like /misc can be repaired and mounted again, using the right steps and procedures....
Then I believe TWRP Recovery will mount partitons again and work, and we will be able to install/flash new ROM... Phone will boot into OS again...
We need Somebody with enough technical know-how to run Terminal Shell commands and repair corrupted android partitions.
Please if someone can help, would be greatful...
I used my Yuphoria for 10 months... now lying useless for one year...

You just gotta flash regular CSC and not home CSC. It will wipe your device but it fixes the problem.

Galaxy Note 9 Bricked?? Help!

Hi,
I hope someone can help me. I managed to get locked out of my new galaxy note 9 and decided to try to flash fresh software onto it. I have flashed phones a few times before and never had an issue.
Whilst the software was flashing in Odin it seemed to get stuck and so I used the shortcut to exit download mode and unplugged the USB from my computer thinking I could just try again. Since I have just had the phone stuck on a loop of a blue screen "installing system update", followed by "no command" and then a black screen which I have attached a picture of. I have tried all combinations of keys with no hope of entering download or recovery mode. If I hold both volume up and down as well as power button I get to the samsung loading screen but then this simply loops and goes back to what I described before if I release the buttons.
I really hope someone can help as it seems I have bricked by new phone. Sorry if this isn't the right place to post but I'm a new member here.
Cheers in advance,
John

Can you get it to boot to a screen that says something like "encountered an issue, connect to Smart Switch"? If so, you "should" still be able to flash it via Odin or connect to Smart Switch and flash the device to recover it.
Or, you can try a USB jig made for Samsung devices, it's a tool that forces the device into download mode, they are only about $3 - $4 USD on eBay and other locations.
Or you can try the "300k resistor" trick or the "301k resistor" trick. They also can force a Samsung device into download mode, if possible, but there is no guarantee that the jig or the resistor tricks will work.
You are getting signs of life so there "should" be something that can revive the device.
You might have to send it to a shop that offers a JTAG service or replace the motherboard. The JTAG service is also not guaranteed.

Seriously could use help flashing custom ROM to Oneplus 8t (Tmo-variant) I am at my wit's end

Ok, first off let me say thank you in advance. I had the Oneplus 7t and (Tmo) and played hell with it trying to root until I found that MSMTool and then had a hayday with it. Now I have the 8t, I have been waiting for a working TWRP because I really like TWRP and I really like Magisk. As of yesterday my stock Rom was fully rooted with TWRP, Magisk, and busybox. It had been that way for several days with no glitches or errors, so obviously bootloader unlocked, phone is carrier unlocked and got my oneplus unlock token last tuesday (5 days ago). On my 7t after trying several ROM's I settled on Havoc-OS so with my 8t I was just going to go straight to Havoc-OS even thought I might try messing around with a kernel update at some point in the near future. BUT...... somehow I have angered the Android God's and am being punished. I have been through much frustration in the past with things Android, have always been able to figure it out thanks to XDA, but today I must humble myself, finally make an account and ask for help. To the best of my recollection here is what I have done with the results.
But before that my current state is, I can boot to TWRP recovery, fastboot, bootloader, EDL and all that but I wiped partitions prior to starting the flashing process so right now I can not boot to system.
I started at techsphinx.com/smartphones/install-havoc-os/ It is a very straighforward guide. but gave error 7, which I believe is wring device error so I checked and it's the kebab havoc like it should be (I think, I'll get to that in a moment) so I look it up and everything says to get in to the file and find the update binary and update script and edit the update script, blah blah EXCEPT that in my copy of havoc-os in the called out directory I have different files. Mine are otacert and metadata. two completely different scenarios. otacert is a binary file while metadata when opened with notepad gives this text:
ota-property-files=payload_metadata.bin:1784:116801,payload.bin:1784:1262105569,payload_properties.txt:1262107411:156,care_map.pb:737:1000,metadata:69:621

I can't remember when was supposed to be remarked in the updater-script file but there is nothing like that in this file. That is all that is present in this directory, META-INF/com/google/android
Everything I try to push to the device errors out before it completes with a broken pipe error, adb sideload is similar in that it won't finish the transfer to the phone. Now anything I try to do in TWRP gives me error can't mount partition_name. I had a nandroid backup but I can't use it because partitions can't be mounted.
I wondered if it was the tmobile variant thing so I tried the msm tool for switching tmobile to universal edition first but I can't get msm tool to work in my device manager the now soft-bricked device shows up as the QS BULK device which is not the right one so I install the automatic driver installer for the qualcomm usb drivers, no effect so I follow how to install manually and windows will not let me and tells me it's likely that the driver file is corrupt or has been tampered with.
My frustration level right now is just before the part where I take a hammer to the phone and make as many small pieces as I can.
The state of my phone right now is that I can't even get it into edl mode because I can't get it to turn off. reboot to power off, holding volume up and power both leave it to when I push both volumes in the screen comes on and I am in bootloader mode. I am at a complete and utter loss.
I need my phone for work tomorrow

@Frustrated_AF,
Regarding the QualComm device driver: I've attached my notes on how I installed the MSM Tool (including the QC driver) in case it's of any help to you. (@Unbrick Instructions.zip). Just note that my phone is a KB2000.
If you can get into bootloader mode, than you can flash TWRP. Get it from https://forum.xda-developers.com/t/...recovery-project-8t-kebab-2021-09-04.4302449/
And once you're in TWRP you can install the Havoc rom zip file using the instructions in post #2 in the TWRP thread. Get Havoc from https://forum.xda-developers.com/t/...8-for-oneplus-8t-official-2021-08-26.4293817/.
Note that the Havoc thread installation instructions were written before TWRP for the 8T was available. And, yes, I've installed Havoc using TWRP so I know it works.

Thank you, I have one issue (at least) that I can't find anything on in your instructions... I have been unable to install the usb drivers, on 2 different laptops one old one new one running windows and one running Linux with Windows in VMWare. same thing both times. I have tried the oneplus exe file, the qualcomm auto-installer andstlil show up as QUSB_BULK_ CID...... When I try to manually install by clicking on let me choose one Windows won't allow it. Windows says the file is possibly corrupted or tampered with. So I am unable to use any of the MSMTool versions I have tried.
Any ideas on that?
Cancel that. Please forgive me if I seem panicky if I can't get my phone working by tomorrow morning there will be hell to pay at work. So in your instructions where you write:
"If it shows up as QHUSB_BULK, it means Qualcomm driver wasn't installed automatically by Windows Update. Download the latest one from Microsoft website at http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab (source https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008 ), extract the files, then install it manually by right clicking on QHUSB_BULK and selecting "Update driver software" and "Browse my computer for driver software" to where you extracted the CAB file and selecting that directory."
I downloaded the file (brought back memories from doing my 7t) and extracted it to a folder on my desktop oddly enough without even updating the driver my edl mode device was detected correctly.
Working on the rest I'll get back to you shortly and once again I can't even begin to express my thanks!

@BillGoss Ok hopefully this will be the last question and it might be a dumb one but I'm not wanting to screw this up any more, In post #2 paragraph 2, bullet point 1 at https://forum.xda-developers.com/t/...recovery-project-8t-kebab-2021-09-04.4302449/
He states "sideload/flash ROM + installer" if I sideload the ROM it's going to install it, I don't see that the installer would go onto the device??? That URL is from the RECOVERY part of it from the ROM part of it at the URL https://forum.xda-developers.com/t/...8-for-oneplus-8t-official-2021-08-26.4293817/ under "installation" it describes a process of altering the RO M files payload.bin and then putting the pieces back together then using ROMinstaller.exe while phone is in fastboot mode.
Could you shine any light on this for me?

Like I said, the Havoc thread instructions relate to the pre-TWRP method. And I've never used that method.
The TWRP instructions say to sideload the rom and installer (TWRP installer zip) because installing the Havoc rom also installs a recovery, thereby replacing TWRP. That's why you need to reinstall TWRP after installing Havoc.

@BillGoss Thank you for your patience with this. I just assumed that learning what I learned when I did my 7t would transfer right on over to this and it would be simple... Haha. So now this... sideloading ROM at 47% from my powershell window it stops and says "adb: failed to read command: No error" On my device:
Flashing A/B zip to inactive slot A
step 1/2
step 2/2
Failed to mount '/system_ext' (Invalid argument)
Failed to mount '/product' (Invalid argument)
Failed to mount '/vendor' (Invalid argument)
Failed to mount '/odm' (Invalid argument)
Updating partition details...
Failed to mount '/system_ext' (Invalid argument)
Failed to mount '/product' (Invalid argument)
Failed to mount '/vendor' (Invalid argument)
Failed to mount '/odm' (Invalid argument)
...done
Devices on super may not mount until rebooting
recovery.
To flash additional zips, please reboot recovery to
switch to the updated slot.
Leaving me clueless as to what has gone wrong or what to do about it. Any ideas on this one?
Edit; It worked! I did nothing else except rebooted it and it came up fine brand new havoc-os so far nothing at all wrong. I have no idea why all the failed to mount errors and I don't think I really care all that much it works!!! I'm going to flash twrp and magisk and be done for the night with it. @BillGoss I can't thank you enough. You have saved my bacon [email protected]!

Glad you're ok now. Those error messages are common when installing roms because those partitions (what used to be the system partition and is now a set of virtual partitions inside the physical super (sda15) partition) don't get properly setup until you reboot.
The 8T is a virtual A/B device which makes life more complicated than the old simple partition and straight A/B partition devices.
