I think I've ruined my one plus 3t

Hi all. Phone is rooted and unlocked. Have twrp installed. Made a twrp backup, downloaded a new ROM (aosp). Wiped phone as in op, flashed new ROM & gapps. Upon restating, phone asked for password. I'd made sure that I'd got rid of security seetings before making backup. Tried to reinstall backup, phone boots into startup screen, then again, asks for "to start android device, enter your password". Please help.

Try deleting this file in twrp using the file manager.
/data/system/locksettings.db

Hi many thanks....but when I go into file manager, there is no file for data????
I think I've killed the phone. Any way of completely wiping and starting again?
The 3 buttons at bottom of screen. When I press the right button, message I get is:
Failed to decrypt data.
Unable to decrypt with default password. You may need to perform a format data.
Updating partition details....
.....done
Unable to mount storage
Full selinux support is present.

Glad you came here, it is simple to solve this.
1. put your device into bootloader mode
2. connect your device to pc via usb
3. install minimal adb and open command prompt in that minimal adb folder.
4. enter command - fastboot erase userdata
5. solved. but sorry, it will wipe your internal memory too.
you can even try wiping data with twrp, but it'll usually won't work at this stage. so follow the command. cheers.

Thanks man. I managed to get it going but only by wiping data. Lost my backup and ROM seems to have flashed but is missing root

Simply flash supersu 2.79 from the XDA thread, everything will be back alright.

Zip files not showing in TWRP??? Can not flash...

I've been able to do the beginning root process, but after entering TWRP I can not see the SuperSU zip file. I went back and transferred again to the internal storage- but my PC (Windows 10) said it was already there (I went ahead and added it which over wrote the original file)!
After I went back into TWRP- it is still not showing there (or the no-verity zip file or the aptX zip file which I ultimately want to install. ) It says also there is 0mb in the folder.
How come my file is not showing in TWRP? I have toggled the image/zip file setting in TWRP so that is not it...
Thank you!

Is it just this one file/folder or in the complete system?
Problem might be because of pin/pattern error. Hence TWRP might not be able to decrypt the data.
One working solution to this is complete factory reset which will erase internal memory ,
I suggest copying your internal memory to PC. Then goto bootloader and type
Code:
fastboot erase userdata
.
Then goto TWRP and advanced option and sideload Oxygen OS Rom.
The above process is highly experimental however I was able to do this successfully once when i had the same problem.
Might search a bit more before proceeding.

Well, I rebooted and everything worked... I was just hesitant to do anything... not sure what actually happened... but all seems OK now. Thanks for your reply.

[CLOSED]Vivo XL2 TWRP 3.0 and Root

I must note: I use linux. I only used Windows because SPFT Linux version gave me a chip mismatch error I couldn't fix easily.
1: Please read. It explains what problems might arise. Especially post #6 and #13.
2: There are 2 versions of the scatter file. The MT6735 version is what I used successfully. The MT6737Tmod version is what comes from post #6 & #13.
3: Please use each scatter file to Readback your boot and recovery partitions first, renaming as fit, so you can have a backup BEFORE ANYTHING. Then test unpacking them to see if everything went correctly. Then readback every partition in the scatter file so you don't have to depend on the stock ROM for a backup. I didn't and it led me to take this route.
3: Seem to be a difference in the naming of the scatter file and sizes of system, cache, and userdata inside from the stock ROM and what works..
4: DO NOT choose Format+Download until you know which scatter file works, unless you want to chance a Hard Brick.
5: Wiping the dalvik and cache in stock recovery before flashing TWRP seems to be the best thing to do to avoid boot loops or a hung boot.
THIS ROOT PROCESS WAS DONE OVER THREE DAYS OF CAR WORK, DRIVING, FAMILY, AND COMPUTER WORK. MOST OF THE TIME SPENT WAS THIS MORNING TRYING TO GO TO SLEEP. DIDN'T HAVE TIME TO DOCUMENT AND TAKE PICTURES. THIS WRITE-UP IS FROM WHAT I REMEMBER DURING THIS PROCESS. IF I CAN REMEMBER SOME VAGUE DETAIL THAT YOU NEED, GOOD. IF NOT, DON'T STRESS ME. THE HARD PART IS DONE. A GOOGLE SEARCH OF SOME OF THESE PROGRAMS WILL GET QUICKER RESULTS IF YOU DON'T HAVE THEM. THE MAIN THING NEEDED FROM MY RESEARCH WAS THE SCATTER FILE. LINKS FOR SCATTER FILE AND RECOVERY IMAGE ARE BELOW.
Looking for a way to root first day getting this phone in February. Read this post last Tuesday about MT67xx rooting, thanks lsemprini. Spent two days finding which versions of the programs work with this phone, already had the ROMs, drivers, and tools. Dove right in.
I downloaded the ROM from needrom. Scatter file was unusable. Wrong chip error. Phone reads MT6735 scatter file read MT6737. Did a manual diff. Used SP Flash Tool v5.1524 to flash, formatted instead of downloading by mistake, cord got pulled, Hard brick. Fought with Windows7 to get drivers to recognize a hard brick. Still don't know how I did it but it read then flashed. Looked like another hard brick but SPFT would recognize it for the Memory Test. I just held power+vol_down with just charging block power to get it to come on. Sometimes just one of the buttons was enough to get it to power on and start a bootloop. Took two minutes sometimes. Flashing the wrong recovery led to bootloops. Starting SP Flash Tool and plugging in the USB to the phone as soon as it powers off during a loop will let the preloader "register" and the images to be flashed. Flashing from a stock ROM will lead to IMEI being erased. Used SN Write Tool v1.1716 to write the IMEI numbers. Got them from the side of the box. The MD1_DB and AP_DB files needed are in the stock rom.
Ported TWRP, credit to jemmini for the post https://forum.xda-developers.com/vivo-xl/development/recovery-t3311601. Used that recovery as a base. Ported according to the myriad of guides that I have been reading over the past few days. None of them worked as instructed, had to modify trial and error style. Finally got TWRP to read the internal partitions AND remain after a reboot. A lot was going on when I did this. Not sure if I formatted before, I remember flashing a lot of because of something. I mounted the system just in case & flashed SuperSu from chainfire's website, no formatting afterwards. Rebooted and installed SuperUser and BusyBox. I tried adb and fastboot. They work but not for everything. Hooked phone up to computer with debugging enabled.
Code:
adb root
gives a shell, no errors unlike before. Edit: ADB won't let me start as root anymore.

When i connect the device after clicking download, it says "CHIP TYPE NOT match!"
mind you the device is off, i tried to troubleshoot but still getting the same error.
any help would be appreciated
UPDATE: Im thinking it has to be the scatter file, but im not sure.
UPDATE: I got it to work, after flashing superSU, my phone wont boot past the initial white Blu start screen.

[QUOTEUPDATE: I got it to work, after flashing superSU, my phone wont boot past the initial white Blu start screen.[/QUOTE]
Try powering it off, booting to recovery and then wiping dalvik and cache.
The longest it took to get past that logo was 15 minutes. It is either encrypting or decrypting. Didn't get any type of messages until after root, and those were optimizing messages. Only one came through before rooting when I interrupted the boot process and that was about encrypting the phone. Phone was encrypted before root, now it is decrypted. Could have something to do with that. Try wiping the cache and dalvik after flashing. I actually flashed it three times in a row. The third was after mounting storage then flashing the SuperSu zip. Once you see the next logo with the colorful circles and hear the sound it might be another wait. That is where it let me know it was optimizing.
I must note: Please use scatter file to Readback your partitions so you can have a backup BEFORE ANYTHING. I didn't and it led me to take this route.

Good. I had to name it that because of the chip mismatch error. It was from the V7 ROM. The other two are updates. I also messed up big time along the way. My phone always read MT6735 but it does have MT6737T in different files. I always wondered about that. I got it to work without buying another phone.

It seem that the phone boot logo never goes away. What should I do now?

Hope you Readback your original recovery and other partitions. I didn't and worked hard to get it back. When I just flashed the recovery and something went wrong, it reverted back to the stock recovery.
Try doing this:
1. Start SPFT with the reçovery you want to flash.
2. Hold down the power button. AS SOON AS IT VIBRATES, PLUG THE USB CORD IN.
3. Hopefully you timed it right and it will flash and boot.
Sometimes it took 15 minutes to get past the boot logo.

Here what I did so far
1. Format using SP Flash Tool
2. Download /// By Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) Which it check all the boxes AUTO ///// It works but I didn't change the recovery.img like TWRP.img
Download it
It works normal.
___________________________________
But I want TRWP.img to be my recovery for root (SuperSU)
I try SP Flash Tool to change the recovery img to TRWP.img /// Using Scatter-Loading Files (MT6737T_Android_scatter.txt {From Rom}) I UNCHECK ALL BUT RECOVERY.IMG
Before this happen I didn't factory reset or Format anything yet.
It work to Recovery.img but THE BLU LOGO IS STILL LONG
I feel like it not working

Try flashing stock ROM, wipe data in stock recovery, then flashing TWRP, wipe dalvik.
If that don't work, wipe data then flash stock ROM with TWRP recovery, wipe dalvik.
The scatter file from the stock ROM gave me problems. Had to modify mine.
Don't forget to restore your IMEI afterwards since you formatted+flashed.

I will try

The one I attatched on the first post #1 is my modified scatter file. The mods included changing the size to the system, cache, and userdata. Just compared all three. The stock MT6737T scatter file and the V12 ota scatter are the same. The one I changed, MT6735, have the file name, platform name, and partition changes. I don't know why I had to modify it., especially the size parts. It all worked when I did that. I basically gave up on it because of a hard brick. Then I remembered reading MT6735 in some file a few months back while roaming the file system. Made the changes and was back in business. Maybe you need the stock scatter file, here it is.
It's what the end result of this post @ANJIII did minus the size changes..
He just did the name changes and it worked for him. Ya'll seem 180° from where I was.
The second one is from the V12 OTA update. It is very minimal, must be all that is needed for a scatter file. Not really sure tho. Hope it is just scatter file issues.
As long as SPFT is reading your phone, it's still a chance on it all working out. That is how I viewed it.
@andromedaXVIII Don't know if you got it working. This might be a potential solution.

I take it TWRP flashed successfully, it is having a problem reading those four partitons. Possibly encryption is stopping you. Try flashing this in TWRP before anything else to remove the encryption.
I didn't get any errors. I know the userdata partition was different in the scatter files. That could be the reason for /sdcard not being recognized. Must be a difference in the layout of phones, not really sure. My protect_s, protect_f, and nvdata partitions and /sdcard all mount fine, pictures attached. I am able to do a backup in TWRP. I have been playing around with porting different ROMs and came across an issue similar to this. Had to change some lines in updater-script.
I checked fstab.mt6735 file in the stock recovery, the modded twrp3 recovery, and stock boot recovery to make sure I didn't make any typos or leave anything out. They all have the same lines. Had to do this:
Code:
("ext4", "EMMC", "/dev/block/mmcblk0p5", "/system")
in the updater-script I was working on. I got ahead of myself flashing a ROM and was stuck on the 1st logo screen. Held power+vol_down to get it unstuck. Yes I was all calling myself kind of names like I'm sure some people have done following this guide.
Which scatter file you used? Did you do a readback in SPFT with the WORKING scatter file and mount one of those images to check if you can read and write the files. I mounted system.img from the stock ROM to make sure I could read and write the files before I started with flashing. I'm thinking there is are internal differences in the XL2s. You might have to reflash using the stock ROM with TWRP as the recovery with the Format+Download option since you got TWRP installed.
Once I get through playing around with trying to flash this ROM, I will restore and try to find all the partition mappings and update TWRP to work with the format from the updater-script and see if that work. Will let you know what happened.

can you send us your vivo xl2 specs because there are two versions of xl2, V0070UU and V0070EE. Mine is V0070UU. I just did some renaming and editing in the scatter file of MT6735 and it bootloop once after I installed the twrp. I restarted my phone during the bootloop by holding the power button. After that, I opened the twrp to install the supersu then wipe dalvic cache. You may now boot up the phone and it took 10-15mins to use it because the system shows that it optimizes 205 apps(in my case, maybe because I have installed numerous apps). After that my phone is usefull again and I installed V4A because that's the only reason why I wanted to root this phone.

Here is all the information I have pulled so far from the phone. Have a screenshot attached from About device in settings. The attached zip file is all the information I could think to pull using adb . The attached file is my partitionlayout. I just ran cat against every file to see what it would give me and redirected the output. Using adb while the phone is in recovery let me pull and read the files I couldn't while the phone was booted.
@Alexis96312, try to run this command in terminal to get your partition map:
Code:
adb shell "su -c 'ls -l /dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/'" > someFileName.txt
I have mine listed in the zip file as partitionLayout.txt It will list which names go to what device in /dev and save it in your current directory. The file can be used to get the correct partition layout on your phone. Post the results and I will repack the recovery to see if it will work for you. You can do it also with Carliv Image Kitchen, it has a menu :good:. You will have to modify the fstab files in the ramdisk folder of the extracted image to what the partition map specifies. I went thru all of them to be sure when I first ported TWRP.
@ANJIII is correct about the different versions, nice catch. I forgot about that. I assumed you had the V0070UU version like mine, fault on me for not asking. Mine specifically says BLU_V0070UU_V07_GENERIC 25-11-2016 09:46. I'm thinking the GENERIC part comes from me having to flash the stock ROM. I think it had BLU_V0070UU_V07 with user/keys before I bricked it and had to flash the stock ROM. Got three extra apps that I instantly removed. Seems like the stock ROM function the same as before bricking flashing stock.

It look like the pid:vid aren't recognized correctly. Usually a reboot will help.
Are you connect using adb while in recovery? If so, see if Windows will install new drivers for you. My Linux box read mine as a Samsung at one point. Try running the ls part of the command in TWRP terminal.
This is where I fought with windows when the cord got pulled during flashing. I never got an error like the 2 at the top, always like the bottom one. I kept adding legacy hardware in device manager until one of them worked. The Linux version of SPFT always give a chip mismatch error. Wish it worked so I won't have to boot to Windows.
I kept doing format+download and and plugging the phone in until Windows recognized it because it was in a bootloop when that happened. You need the preloader to be recognized.
Both stock ROMs are on needrom.com. I downloaded the UU version, the EE version is what you might need. I'll pm you a link to my backups from TWRP to see if they will work for you. Same thing happened to me playing with the new ROM. Restoring my boot and system got it back working.

I might need some assistance. (EVA-L19)

After unlocking the bootloader, installing TWRP recovery and rooting my phone with SuperSU (v2.82), I was preparing to install a custom ROM (more specifically the Resurrection Remix 7.1.2.) all in all, things ended up going out of hand and I accidentally deleted my internal storage, losing every single bit of my existing ROM, not to mention the RR ROM file as well. Now when I try to wipe, I can't, it usually says "Failed to mount '/data' (Device or resource busy) and "Unable to mount storage".
I tried using ADB sideload but to no success, only the same message. What I can understand is that the previous data is gone, I tried changing the format of data, system and cache to FAT & exFAT but it still did not resolve my issue.
I'm out of options here, I don't want to have to give up this phone because of my stupidity.
I also tried flashing the LineageOS 14.1 ROM to see if anything was different, here is what it said:
Installing zip file '/sideload.package.zip'
Target: HUAWEI/EVA-L09/HWEVA:7.0/HUAWEIEVA-L09/C432B361:user/release-keys

unmount of /data failed; no such volume
Patching system image unconditionally...
detected filesystem ext4 for /dev/block/bootdevice/by-name/system
Script succeeded: result was [1.000000]
Although it said succeeded it clearly did not work and I am sitting without a ROM. I'm not smart when it comes to these things please help a guy out.
(Is there a way to going back to completely stock EMUI 5.0?)
Cheers.

EMUI 5.01 requires encryption, which you obviously removed.
Search for DC Unlocker, it can probably fix it for 25 Euros

I'm terribly sorry for being THIS stupid. As I'm looking into this even more, I'm conflicted about the credit amount I need, been scrolling through the list and I can't really find my problem involving firmware I suppose.

People usually buy for 15 Euros. It may help you, Chrome will automatically translate from German

I'm not educated about DC Unlocker but that is NOT neccesary here. You can easily repair the /data partition by flashing the stock recovery via fastboot, formatting data with that stock recovery and then flashing TWRP again. After that TWRP should be able to read the data partition again.
You can easily go back to stock completely and even restore your bootloader by doing a "rollback" to Android 6. (dload method). After that you can normally upgrade from there though EMUI to the latest version of stock.

I've tried using eRecovery to format the data but to no success, I can't even use the touch screen for some reason, (I know about the volume keys, but when it comes to selecting the Wi-Fi, there is no success whatsoever). If you do know a fix for this, could you possibly walk me through this?

UPDATE: I flashed the stock recovery image and it showed me the wipe cache partition and factory data and system reset, I tried both, only the cache one succeeded, the other one failed. I saw a post that directed you to flash boot.img, recovery.img, recovery2.img and then system.img, I did that, but I couldn't boot into my phone - the good thing is however! That I can use my touchscreen in the recovery now.
Obviously the second time booting into EMUI recovery it prompts me to 'Download latest version and recovery', I try to connect to my Wi-Fi, seems okay but then it suddenly fails. More specifically it says 'Getting package info failed'. Save me please :crying:

So this "erecovery" never worked in any way for me (the one which offers you to download the latest version).
Instead you need the normal recovery you already used. Formatting failed for me the first time too, try it again and then it will try to format "low-level" which worked for me.
Go directly into fastboot from that, flash TWRP and go directly into TWRP.
After that should be able to use /data in TWRP. As soon as you are able to start TWRP without any error messages (like "Device busy" or something) go to Wipe and then format data.
Important: check which partition type you have! For EMUI you need "f2fs" and for lineage you need "ext4". You can see and change that in TWRP under Wipe -> "change or repair filesystem".
If you have any more questions, just ask.

So what you're saying is, as soon as I get my data sorted and my partition set to the right one I should be able to install the custom ROM. I could use data and even formatted it, tried installing Lineage but I must've had the storage on the wrong type, now I'm back with the same issue, I'll try to fix it and post my results here. Thank you!

Update: It did NOT work, tried flashing LineageOS through ADB sideload, it was going fine before the bar completely filled up around 50% of the way done, it said 'detected filesystem ext4 for /dev/block/bootdevice/by-name/system' and in the next line it said 'script succeeded: result was [1.000000]'
Help me, I'm begging you, at the moment I don't have an access to a microSD that has the capacity to hold the stock files to do the dload method, therefore this is my only hope.

Whats the error? Why doesn't it work? What happens when you try to boot?

That's what I'm trying to figure out, when I try to boot in it's just stuck on a boot loop. Unfortunate..

Remember that you have to what *a while* for the first boot. Only if you see no change after 5-8 minutes or so something is definitely wrong.
Have you checked in TWRP if your /data partition is ext4?

I know, but it was flashing the Huawei logo and the unlocked bootloader warning continuously. It was set on EXT4 but as I was saying, it said script succeeded at 50%.

That just said that /system partition is ext4. That is default even for stock I believe. You need to check for /data.

I deliberately set the data partition to EXT4 before installing

Can you check in TWRP if it actually says /data is ext4?
Which lineage are you trying to install? Don't you need a vendor.zip for some of them?

/data is indeed on EXT4, and I was installing the one that was on the room section.

You have to format data using the type "yes" to continue method. Then use twrp's menus to reboot back into recovery. Mount /system and /vendor in twrp then flash it. If you still have a problem, then try the 5/21/19 release of the disabler.

@Spaceminer No, that's nonsense! Data is mounted correctly and is fully unencrypted. See screenshot where you can read "Updating partition details... done" There's NO error message.
That's the first thing...
Second, there's no need to mount sth manually, the script itself will do this if necessary!
@VineelKumar Download the dm-verity-disabler.zip by Zackptg5 from
https://zackptg5.com/android.php#disverfe
This will work with your device.

It doesn't show data as mounted. It shows the external sdcard as being mounted. And there is an error, twrp is giving error 1, and the disabler is also showing an error saying it can't find the boot block location. This means twrp isn't able to modify block devices or mount them properly. What I told him to do will fix the problem. The script doesn't mount anything correctly if twrp is not able to run the script... I know what I'm talking about. I wouldn't steer the guy wrong.
Edit: I'm definitely correct. What I said is actually mentioned in the official twrp thread for this device. It says; "If you format data (Not just factory reset) after decrypting you must reboot into recovery and format again." - direct quote from the instructions, under notes.

I flashed the same .zip with /data, /system and /vendor mounted properly and ran into the same error... (see screenshot)
To mount a device block it's not neccessary to have /data mounted.
The .zip is incompatible with Moto g6 - that's all!

Thanks it worked fine. But for some reason the mobile was struck in boot loop(just warning message on screen saying, you have unlocked bootloader for couple of seconds and then same thing appears again), any idea how to fix it ?

Yes, do it manually. The disabler.zip does two things on your device.
1.) remove dm-verity
2.) disable forceencryption of /data
The magisk.zip also removes dm-verity within the installation process. So you don't need the disabler.zip for this.
To remove forceencryption you have to follow a few simple steps which are given in my instruction below:
preparation:
You have to be on the latest stock firmware with TWRP installed and nothing else.
Boot into TWRP and format /data (do not wipe it! you must use format). Then reboot directly into TWRP!!
Now let's start to remove forceencryption.
1.) place the attached .tar.gz file in your internal storage (/sdcard)
2.) mount /vendor in the options menu and open TWRP's terminal command under advanced settings
3.) type in (or copy it from here)
Code:
tar -xvzf /sdcard/fstab.tar.gz
4.) at next boot your device will be unencrypted
Now don't reboot your device and stay in TWRP to install the magisk.zip v19.3!! That's important to flash v19.3 instead of the latest v20.3 otherwise it causes a bootloop!! I don't know why it does but you can later update Magisk without any problems through the Magisk Manager.
Magisk will now remove the dm-verity during the installation process. That's a part of the installation script of Magisk.
When the installation of Magisk has finished you can boot your device into system. Maybe it reboots one time but don't care. Also the bootanimation will take some time due to unencryption of /data. That's quite normal.

I appreciate your patience, WoKoschekk. I for one appreciate the guide and insight into the reason root must be achieved this way. I was using 20.3 and 18 the whole time. I was successful with your instructions the first time. It became stuck on boot after the initia reboot, so I pushed fstab and magisk again and it was fine. I remember that on one phone, encryption wasn't a problem if you had your pin or password. Could it be the same here provided there was no fingerprint assigned (might be the original pixel)? I'm guessing this TWRP can't decrypt? Just curious, because N/A balogna.

I'm glad to hear that!
TWRP for Moto g6 can't decrypt your data. That's the reason why you must disable forceencryption to use TWRP.

I don't have a SD card, so I put the file into the TWRP folder. I then used,
Code:
tar -xvzf data/media/TWRP/fstab.tar.gz
Was that the right location?

/data/media/0 = /sdcard
/external_sd = external SD in SD-card slot
