[q] oneplus one urgent!!!! Help

Hello.
during this evening i wanted to flash my ONEPLUS One and to do this i downloaded a new ROM (BlissPop) as well as rooted my phone (unlock bootloader, installed TWRP and root the phone). Then i put the Rom.zip on a folder in the SD card (internal). I boot the phone into recovery and then i make a factory reset, wipe cache and dalvick and when i search for the zip to flash it i couldn´t find it anywere. So now i receive the message that i dont have any OS in my phone. I still have the bootloader unlock and i stil have access to recovery i only don't know how i put the zip file in sdcard (internal) because my computer dont recognise my phone when i connect it.
Could you help me to resolve this problem? it´s very urgent because i dont have phone now.
Thanks in advance

Looks like you wipe your internal storage accidentally. Do you have MTP enabled in the Mount menu in TWRP?

Yes i have.
When I touch in the middle button in TWRP Navbar I could see the following information:
Updating partition details...
...done
Full SELinux support is present.
MTP Enabled
However the mount appears not working because when i touch in Disable MTP button i could see the same message.
I already try ADB sideload too but it fails.
Its quite strange because when I access the Wipe Menu, i have the following message:
" Factory Reset
Wipes data, Cache, and Dalvick (not including internal storage)"
then i have two buttons 1- Advanced Wipe and 2- Format Data
I touch the second. In the sdcard partition i still have the TWRP folder but whe don´t see the other folders. I have in the same partition a folder named ROMs where i put my new ROM but it dont appear to me.
many thanks man for your help.

Right now it's probably best just to use fastboot to flash the stock images to get your phone booting again. Go to section 8 of my guide:

you´re the one. Thanks a lot man my OPO is booting again .
I realise that I were very nooby here because TWRP has a slide button that says wipe for factory reset. I should to touch in this button regard the Format data button, its my fault and a very lack of attention. Fortunately there are guys like you.
Once agais, thaks a lot.

Great news. When wiping, it's probably safer to go into the Mount menu in TWRP, then select Advanced Wipe, and then you can select exactly which partitions you want to wipe.

Only one more thing. What is the folder that i should use to put my Rooms for flash? Now I´m a little afraid that when i perform a full wipe i dont see the folder with the rooms again. So what is you suggestion?
Thanks a lot once again.

It doesn't really matter where you put them, I have a dedicated folder for ROMs so they're easy for me to find. But as long as you use the Advanced Wipe menu and only select system, data, cache, and dalvik cache (not internal storage) you'll be fine.

failed to mount /data

SOLVED
I rooted my s7 and installed twrp. I tried to do a nandroid backup in twrp and got the message that it couldn't mount /data. It turns out that by not performing the data format step in http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770 TWRP couldn't access /data. I did the steps over again and all was well.

I do have root, twrp does run when I boot into recovery. However, whether I select to allow modifications to system or not, twrp does not see the internal sd card.
I followed these instructions to root: http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770
However, I did not do step 10:
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
Is this the reason that I can't access internal storage? If it is, I can go ahead and do the format data thing. I just would like to know if that is probably the reason I'm having this problem. NOTE: The phone is not encrypted so far as I know.

Internal data is encrypted nevertheless. Only a format will remove this encryption and it is the only way that you can make a TWRP backup of this data.

Frag. Well, in that case, I've already installed TWRP, so presumably I can just boot to TWRP, swipe right to enable changes, format data, flash supersu, and then flash dm-verity and force encryption disabler. Then go through the setup again.
If I could have my way, someone would disable the security deal with writing to the SD card, the phone could be purchased pre-rooted, and I wouldn't have to worry about bricking my phone every time I flash something.
Rant over.

@kettir: You're exactly right!
btw: The security deal is not over when you root your phone. 'I still haven't found what I'm looking for' is a very precise song for this problem.

I had the same issues and succesfully used the sequence proposed by Kettir:
- Enable OEM unlock
- ODIN: Install TWRP
- TWRP: Wipe -> Format data
- TWRP: flash supersu
- TWRP: flash dm-verity and force encryption disabler

[HELP] Internal storage 0MB twrp

Hey guys.
I recently decided to root my Samsung Galaxy S7 and my first attempt I think i soft bricked my phone so I flashed back to the official firmware and then I successfully rooted the phone so I continue and download rootchecker to check if the root worked and begin downloading and backing up my files through titanium backup.
Now here's the problem: When i put my phone in recovery mode, going into the twrp, I can neither wipe system, clear cache, dalvik or data it gives me error something about "Failed to mount '/data' (Invalid argument)
Unable to locate storage device.
Nor can i find any zip custom roms I've downloaded either, it says that my internal storage (0MB) that can't be true.
I don't really know what to do, I've searched as much as I can.
Edit: I am very sorry in case there is already a thread for this type of problem I was very quick in creating this thread, looking around the forum atm for something similar to mine.
Sincerely ~ Guardian

Hi
Did you do step number 10?
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].

Hi guys, is there any way to back up my internal storage before I wipe via flashing with odin or something please? I only backed up using Titanium Backup thinking it was all going to be alright just like all my other devices in the past... I cannot access the system since I get blocked with verification has failed please reset your device" sort of message and thus cannot back up as I am now.

I want to root my galaxy s7 running Android 7.0 but I do not want to lose data. Please help. Does chainfire autoroot package work for 7.0?

Hi mate
CF autoroot is not working yet as far as i know you have to use Super SU zip and TWRP but you do not have to loose your data..
depends in what you want to do, you can install TWRP , root and not format the data partition you only need to format the data partition if you want to access it from TWRP , like to flash mods from the data partition. This is valid if you pretend to just root your stock rom and stay with it.
If you want to root and flash a custom rom then you have to format your data partition

But on autoroot.chainfire.eu a package is available for s7 running 7.0
Not sure if I must flash that.
Plz help me

Hi
As far as i know is not working correctly.
Search Chainfire thread
As i said....you can flash TWRP + Dm Verity+ SuperSu zip and root your stock rom without formatting your data partition, you ONLY need to formatt your dta partition if you want to have access to it from TWRP

THANK YOU!!!

thank youuuuuu!! Took the plunge, wanted to install twrp to make a backup, since i was 3/4 there and either had to install SU or verity disable, i decided to just for for it and install SU... but then i couldnt see the SD card or internal at all. i was so scared it was bricked due to being unable to read!
thank god i decided to mess with rooting and such before any personalizing!

My data partition can't read by twrp. I want to enable data in twrp without format data. In this case, if i only change data partition image from ext4 to exfat in twrp, can this action erase my data?

Hi
Data partition is encrypted by Samsung and TWRP can not access it , that is why you can not factory reset your phone , in order to access the data partition you must format it ( to disable the encryption) so it can be access by TWRP , if you do not plan to use the data partition to store backups or place mods or roms to flash them from there then you do not need to do it
To format the partition go TWRP / wipe / format data ( and type yes) ..... backup, this will erase all user apps and data ( AKA factory reset)

0 mb in TWRP internal storage

I searched for an answer and noticed it's a common issue. I am trying to flash a kernel on to my already flashed rom. I was wondering if there is a more current fix. More importantly, how can this be avoided in the future. Thank you guys!

Its caused by a bug/error with either the filesystem or encryption.
Did you wipe data after flashing the new ROM? Data from stock usually doesn't work with custom ROMs.
Do you have a PIN/password on Android?
Are you using the latest build of TWRP?
Press the menu button at the bottom of the screen in TWRP and post what the error message is in the red text.

It's caused by no root access

Something is probably wrong with the data partition. TWRP should always have root access.
Try in TWRP:
Wipe > Format Data > Slide to format
This will erase the data partition, so backup everything to a PC in Android first if needed. It should allow TWRP to mount /data again.

I've debated on doing this. I'm not worried about losing pictures texts etc as they're backed up.
I read that it essentially leaves the device with no OS. If that's wrong please let me know!

I have found that if I choose Slot A and reboot system it reboots me in to TWRP. If I choose Slot B it runs the OS like normal (except I still have issues using Facebook and it's services).
The ROM works and I can perform all the custom mods on it. I just want to flash a kernel and the problem persists. 0 mb in storage.
It's trial and error at this point. Fail fast fail forward. I have another phone I can use but I love the OnePlus. Any help will be appreciated!

I'm not willing to risk it until I know how to get the custom ROM on to the storage to flash it.

Yes formating by typing in yes will wipe it all,everything including pictures, with no rom on it at all. If u choose to do that, don't close twrp. Instead you should be able mount after wards, once mounted transfer the magisk zip, twrp, and your custom rom(has to be 1.5gb not 200mb through magisk). Flash magesik, install ram disk twrp, install rom. That was a method I've done before but if u want to keep everything there is other way
fastboot boot twrp.img, that command boots twrp if u have it or don't, installing to ram disk makes it permant...this boot command is just a one time thing each time. It's what I do when new firmware update, I loose root but I regain it each time

Never heard of formating data removing the OS, that would be if you wipe the system and normal wipe is like a factory data reset and therefore will not wipe your phone of the OS

I attempted to format. It said
"failed to mount /data (device or resource busy)
"unable to mount storage"

Try this in recovery, sometimes its known to work.
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to EXT2.
Repeat the same process selecting Ext4
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to back to EXT4.
Try formatting data after this.

Since you dont care about the data on the phone I would just do 1 of 2 things. 1st I would reflash twrp on to you phone if that doesn't work then I would just grab the fastboot ROM and just flash your phone back to full stock reroot and install twrp from scratch. I would not try to start repairing partitions. I wouldn't want to worry about screwing up the EFS partition

Well in an update, I formatted the
Storage and now I'm stuck in bootloader screen. It's unlocked but I'm having a hard time flashing a ROM through adb.

I use the twrp version 3.3.1-2
Best would be to just use fast command to boot it
But it should be under wipe/format data/then type in yes

That was what I was trying to have you avoid. If your can boot to fastboot download the fastboot ROM I told you to and run the flash-all.bat file. If your on 9.5.8 make sure you use the fastboot ROM of the same version. Do not flash azip of a different version firmware like 9.5.7.

It happens to me any time I'm in twrp and flash a rom then reflash twrp. It doesn't matter if I flash Magisk or not the issue always happens. What I do is use a USB C flash drive and plug it in when I want to flash/backup a rom. This way I can always access it. After flashing any rom then booting I'm always able to access my internal storage again. It seems like a bug in twrp.
The strange part is when this bug happens your files are encrypted in a 0 folder but you can still copy from your PC to your internal storage while in twrp.

I essentially soft bricked my device. Called OnePlus and they got me up and running. That's awesome that they have that service!

Are you removing all security? Pattern, pin and fingerprints? Are you decrypted? Never had an issue with flashing a ROM causing these issues which is why I'm asking. Something you've done at some point is causing this

I'm not sure what that was. Ironically enough I am now stuck in TWRP boot loop. Hopefully I can figure this out otherwise I have to call oneplus again.
I will admit I may not know everything but it's trial and error. I don't have anyone to really teach me this so I try to read the forums and learn. You guys have been great!
