Unable to mount /system and /data while flashing rom. - Micromax Canvas A1

Hi,
I have installed twrp 3.1..1 recovery. Wanted to update android version to 7 but when I did the advance format from the twrp recovery, its start giving error says unable to mount /data and /system. When I install the rom zip file, at the end it is giving error says Unable to mount /data and /system (invalid argument).
I did googling and tried to find the solution, but problem persist.
Is there any solution and suggestion to get it solved.
Thanks

Open recovery (twrp) go into WIPE>FORMAT DATA then type 'YES' to confirm. This will wipe all your data including media such as photos videos music, etc so make sure you have a backup of all your stuff before proceeding. The recovery will then restart. This fixed it for me and is most reliable.
.
.
If this doesn't help then another method is- Wipe>>advanced wipe>> select data and system and select REPAIR OR CHANGE FILE SYSTEM. In there select ext-4 and then repair. Once the process is done your recovery will be working.

Thank You,
But I did not find the option to choose ext-4 while Repairing or changing the file system.
Any alternate method would appreciated.
Thanks

[Q] Lost with sdcard and custom Rom

Hello,
I've just installed cyanogen 10 and it rocks ! Well done arco for your good work !
I followed instruction for installing the rom i.e wipe cache/data/dalvik and install from zip. It went well.
But when I go to Photo gallery I have the following error : no external storage available
In fact, I can't access my sdcard. I tried to fix permission in clockwork and doesn't solve my problem. In clockwork, I see that my /sdcard folder contains my old data.
So my question is : did I miss something during the installation ? Do I need to format /sdcard ?
Thanks in advance for your help
Regards
Hello,
This morning I fixed my problem. I did a format of all partition (even /sdcard) and let only /external_sdcard unformated (with my .zip files). I reinstall the mod and everything is fine, I get all my partition back and don't have the error anymore.
If this can help someone
Regards
Nice

what are the steps to format /sdcard? do i do it on phone or computer? can you write steps to show me what to do? thanks
Hi dmariadas,
You simply have to boot to recovery mode. When in, go to "Mounts and restore" menu and then format all exept /external_sd.

internal memory without format (NO OS)

Well I ONLY have on my TWRP cell phone and in the internal memory section it marks me 0, my problem is that at the moment of wanting to install a ROM sends me the message "Failed to mount storage" so the "\Data" folder does not have Format, unless I understand and look in other forums but I do not find the solution, try trying to change the format but you can not, I only found the solution for samsung but for motorola no, I clarify that I do not have an operating system. Thanks for whatching and help me please...
==EDIT==
When I applied the command "fastboot flash partition gpt.bin" I get an error when executing it
Whatever you are trying to do, don't fastboot flash anything unless you know what the hell you are doing
Which TWRP do you have specifically, and what does it say when you want to format (not wipe, really format with a new filesystem) the /data partition from the advanced wipe menu?
Thanks for replying, I could fix it but the problem continues with the section that does not let me install stock rom, now I have the venom without sim recognition

[solved] finally I download tool all in one from xda then reboot into bootloader there is an option in Tool all in one called erase all data/decrypt internal storage just press it and select ok >you are done.

Guys Please help. Unable To Mount... error. Tried everythng. Video given.

I have watched a lot of tutorials but nothing is working please someone help
I made a video of the problem and what I tried. Can anyone understand what happened
https://www.youtube.com/watch?v=VaN-y-Worlg
Update: In Data i Changed the file system and went back to original. Didn't work.
I even wiped system. But i guess the only problem is to fix the "data". Since it shows 0 Mb size. But i can't find any way or guide. The ones i did find are too advanced and use cmd commands and toolkits which i don't think an inexperienced user like me should be following.
Some background information: i attempted to install Open gApps and enable Camera2 API. I Entered "read only" mode.
The adb shell commands for enabling it wasn't working (some "proprietary" something shown )
So I tried another method. I downloaded the latest Magisk and flashed it. Then i tried gApps. I don't remember when i started to think what went wrong but yeah..
I found this and I think it may be related.
But I don't understand it properly.
And its and Old post for some other Recovery

Oh yeah didn't do it in the video.. But yeah no good.
Crap, sorry to hear it, hopefully someone better than me chimes in. Good luck!
Why did you wipe internal storage? And what are you trying to mount. If you are trying to install a new rom all you need to wipe is cache, dalvik, system and data. Wiping internal storage removes everything from the internal SD card and if you do this then you have no OS.

At this point i can't care less about the data in internal storage. I just need to flash the official MIUI ROM back, enable Camera2 API and live in peace. At this moment I'm halfway through downloading the ROM but I'm not sure if i can flash it due to the Mount Issue of internal storage. I plan on transferring it to my micro SD card and flashing it from there to System Image. Will it work? And Internal Storage formatting failed in case you didn't notice. Practically nothing worked except the file system change of "data". And even that didn't fix the unable to Mount issue.

Problem after flashing wth global rom

Hello,
I get Xiaomi mix 2s global with:
-Unblocked bootloader
-Installed OrangeFox Recovery
-Installed some Android 10 pixel experience rom
I wanted back to original global rom with stock recovery and reblock bootloader, so i download Global Stable ROM V11.0.5.0.QDGMIXM, put to internal storage and install from OrangeFox.
And now, when I turn on the smartphone, it’s starts, restart and go again to OrangeFox recovery.
In log I have: “Android Rescue Party trigger! Wipe data and caches and/or clean-flash you ROM!"
OrangeFox disables forced encryption by default, and now I need to enabled encryption? How to do it?
So, How to fix it?
I want to back to original global rom with stock recovery and reblock bootloader, bu first I have t turn on system.
Thanks
EDIT:
After installatin PixelExperience_polaris-10.0-20200528-1111-OFFICIAL from OrangeFox, smartphone starts normally, now I want to back to stock rom, recovery and reblock bootloader.
If your bootloader unlocked try formatting your data in orange fox recovery and reboot and see if that fixes it. Just remember formatting data partition wipes everything on your device so anything you want to save be sure and transfer over to your PC first.
doesntwork

I got the same error - Android Rescue Party trigger..." and bootlop.
EDIT:
But I wiped:
Dalvik / ART Cache
Cache
System
Data
Didn't wipe: Internal storage and Vendor.
After that, i installed Global stable V11.0.5.0.QDGMIXM and get the same error, but some settings have been saved - for example my pattern for unlocking.
EDIT:
I did: wipe all, reboot to twrp, flash ROM, and when I try format data, I get error:
Formatting Data using mke2fs...
mke2fs -t ext4 b...
Proces ebded with ERROR: 1
Unable to wipe Data.
Unable to format to remove encryption.
EDiT3:
Success!
I tried once more, and it's ok.
Solution:
1. Wipe all via recovery
2. reboot to recovery
3. flash rom
4. Format data partition (format, no wipe, if mke2fs doesn't work, try with rm-f)
5. Reboot system.
After that everything is ok, at the end uploading stock recovery via adb went without a any problem.
Thanks!
Just to help many others. The trick here, is to format data, not just wipe data from TWRP. You need to hit format data from the wipe menu and type "yes" to confirm. Some things need to be said in plain English.
