Failed to mount /data (Invalid Argument) in Micromax Canvas Juice 2. Aq5001.

I have a custom rom downloaded. But to flash it, I need to erase everything. That I am unable to do because the recovery dosent wipe data. It led to a bootloop. I got back the stock firmware and tried again and same result. Further more, I cant even factory reset. I'm using TWRP 3.0. Someone please help!

If you have a flashing tool then flash the stock firmware again and then give it a try.

Ive tried that 4 times till now. It has been in a bootloop thrice. And I flashed stock. I currently am using stock firmware but want to flash the custom rom. The recovery is failing to wipe data because it is failing to mount data.

Try this
1. Reboot to recovery (TWRP)
2. Select wipe.
3. Select advanced wipe.
4. Check system.
5. Repair or change file system.
6. Select change file system.
7. Select format type.
8. Swipe to change.
9. Select repair.

there is one problem with stock rom. its encrypts the data partition right after installing stock rom, therefore twrp can't access data partition. i had similar problem earlier. this is how i managed to fix.
solution: http://forum.xda-developers.com/showpost.php?p=67980158&postcount=7
i suggest you to stick with stock rom, because right now whatever roms or recoveries are made for this phone are blindly ported (just copy paste roms). i have tried about 3-4 roms for this phone, all had major bugs especially battery related. there is only one developer who made a stable rom so far is beingtejas, search his thread. if you really want to use a custom rom, try THIS rom made by gaurav kesarwani with help of beingtejas that is why i am suggesting it you otherwise it didn't worked for me atleast.

I cannot flash TWRP or any Mods

I just got this phone and i have OEM Unlock enabled. I am due to sell my old phone in few days so i am in a bit panic mode right now :\
When i try to flash TWRP along with the instruction that were here (i tried with only applying both or only dm-verity) the phone started to "start" flashing the Samsung logo but nothing happened and after 15-25minutes i tried to install this ROM and it also shows "Starting up please wait" but it also seems to start up indefinately.
Can you tell what is wrong now? It seems i can flash the stock ROM and boot to it but cannot install TWRP/Root nor any custom ROM's :\

Hey bro follow this.
Install stock ROM.
Boot into it once.
And flash TWRP. Disable auto reboot in Odin.
Then boot into TWRP directly from there.
Now swipe to allow modifications.
THEN GO INTO WIPE ADVANCED WIPE AND CLICK FORMAT DATA AND TYPE YES.
After format reboot into recovery once again.
Now again swipe to allow mods.
Now only install Dm-verity.
Reboot.
Now the phone will boot.
Go back into recovery to install your ROM it'll root the phone.

Sorry but still no dice (waited for ½hours to boot)
The data wipe did not even succeed. I attached screenshots of data wiping plus no-verity install if there is something anyone could use. I do not really understand how this is so hard... I have never encountered this kind of problem with common phone.

@DARKKi
Did You try to format data or just to wipe? You should click on format data and type "yes"

Dude I clearly mentioned, you have to click format data in advanced wipe. First try to read and understand then proceed. Click format data and then type yes and then you're good to go.

Damn. Sorry, i think that when going into advanced wipe there is no format there it's under normal wipe so i only thought that it meant that but yeah my mistake. I should have looked for format data and come to my own conclusions :\
Well first result of format resulted on loop boot and i could not even flash the stock rom with Odin (failed directly) but then i tried to flash TGP ROM via TWRP and it worked! So now i am using the phone as we speak!
Thanks a lot njaya95!

Sure no problem, I'm sorry about misleading you about that format data. Have fun with your phone.

Cant upgrade because of faulty TWRP, need help removing TWRP

Hi,
I accidently flashed TWRP, but i was already on emui9 so twrp doesent work there.
Now i can update the EMUI anymore because when the phone restarts during the install process it goes into recovery (twrp) which causes the update to fail
My question is: Can i remove twrp, maybe by flashing the orignal ramdisk image? pls help

You would have to reflash the recovery partition... Which we don't have, and since TWRP is kind of broken on EMUI 9.... well...
Can you just wipe caches and reboot to get the phone working? The update is stored in the cache partition, if you wipe cache it should boot normally.

Not if you are on EMUI 9... I don't believe so as we don't have the factory image for it, and to my knowledge we can't just dd it or make a backup of it right now. Although you might be able try the downgrade to 8.1 in another thread here, then upgrade via OTA again, but that's your choice.
I haven't installed TWRP on this devices, but basically go to the wipes menu, advanced wipes, and tick anything that says cache in it's name (often Dalvik cache and cache) and swipe to wipe them. This will not harm any of your data or applications, only the cache space. Then reboot.

Just flash your stock RECOVERY_RAMDIS.img*from your firmware. This will repair your recovery.
To extract images from*UPDATE.APP*in the zip, you have to use*Huawei Update Extractor.
