good evening, i have a problem with my phone. i have an exynos7870 j7 2016 with a modded galaxy s20 ultra oneui 2 android 10 rom with root (magisk). it's kinda buggy sometimes but i've had it for a year and a half.
not too often, my OS would randomly go from being powered on to showing the samsung loading splash screen, like it was turning on. i would always hard reset the phone as it would be stuck in this screen and it would reboot normally. this time, however, was different.
when i hard reset my phone after this issue, it took abnormally long to load (usually took around 2 minutes, it was well over 5 minutes this time). i thought it was a bug so i decided to reset the phone again. when it restarted and i realized it would take the same amount of time, i let it do it's thing, only to realize that it would restart and try to boot again. that's when i realized i was in a bootloop.
i'm not sure what caused this (i'm fearing that i corrupted the OS by hard resetting the first time) because (if there's a way please lmk) there's no way to turn on verbose mode on boot and check what the OS is having issues with.
i tried going into teamwin to see if i could check the system log. i did find a system log option, and it was saying that it failed to mount /data. i'm not too sure if this is teamwin's own log or if it's an OS log because teamwin mentioned something about not mounting the system partition and this log doesn't look particularly big and because it mentions the initials "TWRP".
Markdown (GitHub flavored):
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details...
Failed to mount '/data' (Invalid argument)
...done
Unable to mount storage
Failed to mount '/data' (Invalid argument)
Full SELinux support is present.
Unable to mount /data/media/TWRP/.twrps
MTP enabled
Failed to mount '/data'(Invalid argument)
an additional thing to note is that teamwin restarts itself the moment i press the restart button where it otherwise asks for confirmation. i found that strange but i'm not sure if it's related with my problem.
any help regarding this problem would be much appreciated. i want to try to not have to wipe my phone and reinstall the OS because i have some sensitive applications (like lastpass authenticator) that i don't want to lose access to, but if i really have to, then i'd like to know if 1. there's a lineageos build for my phone and 2. if it would run better / be better for my device.
thanks

Hello,
Today I woke up to my phone boot-looping after leaving it to charge overnight, despite it having run fine for close to a month (I have been running Cayanogen Mod ROM and TWRP 2.6.4.3 since I got my Nexus 5).
After a long wait at the Google and Nexus logos, there's a system popup of 'Cayanogen logo" present on the screen. However, right after completing the 'updating of apps', the system popup 'Media Storage has stopped working' appears and the phone immediately restarts again.
Upon booting into TWRP, it presents me with a password screen, which I have never encountered before. After pressing 'Cancel' though, I'm directed to the TWRP main menu.
Attempts to factory reset the phone resulted in:
Formatting cache using make_ext4fs function.
E: Unable to mount '/cache'
Updating partition details...
E: Unable to mount '/cache'
E: Unable to mount '/persist'
E: Unable to mount storage.
Then i am using Nexus Root Toolkit and all are option i am going but nothing to do..
So please Watch this Video and Solved My Problem Please.. Please...
All are Process i am apply...Please developer help me......

I Think my Internal sdcard is corrupted!
Please Help! Reflashing android won't work. I think the partition is corrupted!
Device: Google Nexus 5
Original OS: Android 5.1.0_r1 (LMY47D)
Recovery: TWRP 2.8.6.0
One day I turned my phone off, and later i decided to go into recovery. I believe I went inside Advanced Options and clicked "Fix Permissions." Then I proceeded to reboot. I was busy at the time, so when I remembered about my phone, I saw that it was still booting. It had been at least 30 minutes so I knew it was in a bootloop. I decided to go back into recovery and reflash the system.img onto it. No luck. I realized I had to try flashing the entire Nexus image (using the flash-all.bat). The phone would still not turn on. I tried flashing different versions of android, and here are my findings:
Android 5.1.0_r3, 5.1.0_r1, 5.0.1: all cause my phone to not be able to boot up (stuck on the 4 color flying animation)
Android 4.4.4, CyanogenMod (cm-11-20141008-SNAPSHOT-M11-hammerhead.zip): Allow my phone to boot up.
However, after I found that I could boot onto Android 4.4.4 and CyanogenMod, I realized that I could not get access to the sdcard!
Here are my findings:
When I go to the phone's root folder, I see a FILE called "sdcard"
When I go to \storage, I see a FILE called sdcard0
When I open camera, the app crashes (possibly because it stores pictures on the sdcard).
I tried to delete these files when I had root access with CyanogenMod but the file manager said "can't delete file." When I am in recovery mode (TWRP) however, I can see the sdcard folder and the contents. Just through every system boot, the sdcard is inaccessible.
After I realized that the problem wasn't due to the data on my phone (after flashing many system images), I realized my data partition might be corrupted. Then I went to this site and followed the directions: http://forum.xda-developers.com/goo...o-repairing-corrupted-data-partition-t2577447
The e2fsck command didn't do anything as cmd said "The superblock could not be read or does not describe a correct ext2 filesystem."
Afterwards, my friend told me to try mke2fs /dev/block/platform/msm_sdcc.1/by-name/userdata
I typed that in adb shell and something happened. I started processing blocks or something. Unfortunately now, I am unable to mount the data partition at all. I am also unable to flash the userdata.img onto my phone through fastboot.
UPDATE: When I open up twrp recovery and look in the log I see the following:
E: Could not mount /data and unable to find crypto footer.
E: Unable to mount '/data'
E: Unable to recreate /data/media folder.
Updating partition details...
E: Unable to mount '/data'
E: Unable to mount '/cache/
E: Unable to mount '/persist'
...done
E: Unalbe to mount storage.
E: Unable to mount /data/media during GUI Startup.
E: Unable to mount '/cache'
Full SELinux support is present.
E: Unable to mount '/cache'
E: Unable to Mount '/cache'
E: Unable to mount /data/media/TWRP .twrps when trying to read settings file.
E: Unable to mount '/data'
MTP Enabled
Anyone know how to fix this? Please help, I owe you so much if you can solve this! Reply to me if you're able to help, I'm also new to xda so I don't really know how messages work. Thanks!
Try taking it out and putting it back in. It happened to me too.

By sdcard I mean the internal sdcard (/storage/emulated/0). Nexus 5 does not have an external sdcard slot anyways.
So you are saying you have no apps, no widgets, nothing... /storage/emulated/0 is your main storage which INCLUDES your system files (unless you have a phone or tablet that has a separate internal SD card - would be /storage/emulated/1 ... I am guessing)
I am totally new to rooting, not sure what I've done wrong.
I started trying to root my SM-J727P by installing TWRP with Odin. This works fine, then I added the superSU v2.82 file to the device's microSD card. I went to install tab in TWRP recovery mode->select storage->Micro SD card->superSU.
Then when I try to flash it, a red message appears saying "Could not mount /data and unable to find crypto footer. Failed to mount /data (Invalid Argument). At the bottom it says "Failed to mount /system (Device or Resource Busy). Failed to mount /data (Invalid Argument.)
After this I read that I need to format storage.
I went to wipe->format data->typed yes and the same message appears, "Failed to mount /system (device or resource busy).
I'm extremely new to this so I don't really know what I'm talking about but do I need to disable dm-verity?
Any help would be greatly appreciated.

I now have manually mounted system and no errors showed, after tapping reboot system, the phone entered a bootloop. Not sure if this is supposed to happen or not and if it is, how long does it take?

This happened to me when I was doing my first root with samsung. What I did was completely start over with a new stock ROM and TWRP. Be sure you have all the right things ticked on Odin. What I had to do with my sm-j700p was un-tick auto-restart when done, and when the TWRP was done flashing, I had to remove the battery instead of wait for it to shut down. Then QUICKLY go into recovery mode by pressing the buttons after you turn it back on. Flash ROM. If I remember correctly, I was so good from there, but the timing with samsung when pushing the buttons apparently is EVERYTHING.
And making sure it is the correct TWRP file. I also made the mistake of picking the wrong TWRP file. Same model and carrier...different year of phone. Software version number is where it's at to get the best info.
Good luck!
Hey guys, hoping someone can save me from having to buy a new phone. I either need to fix it quickly or replace it quickly cause my job depends on having one.
I have a Moto 9 g plus.
I wanted to root my phone for a long time and today I decided to try since the Android 11 update ****ed up the camera on my phone anyway.
I followed this guide here
Root Motorola Moto G9 Plus Android 10 using TWRP and Install Magisk
When you have Stock Android on your mobile, You are almost free from bloatware apps. Even if your manufacturer put some apps, You can get rid of them in
www.androidinfotech.com
Everything seemed to be going well except that I couldn't get magisk to install, I kept getting errors in twrp.
I ended up installing the apk for magisk and used it to modify the boot file. I installed the image in twrp and on reboot, it went into a boot loop. I could go back to trwp and after swiping to factory reset, it broke the loop when I restart the phone. The problem is that now it just goes straight to the menu that you normally need to press and hold down and power to go to. I never did get to confirm if my phone was successfully rooted or not, I'm guessing no, and that that is the main problem now, as the phone won't boot up to where I can use apps, and if it isn't rooted, from what I understand, I can't install another rom?
Also, whenever I'm finished with twrp, when I press to reset it says something like "Phone no longer has OS, are you sure you want to reboot?". I read it is from wiping the data or factory reset, but I didn't actually wipe any internal memory, I can still view all files on it and on my sd card.
Maybe you guys can confirm my suspicions that I just ****ed up my phone for good or not.
This is what the error says when I attempted to install a rom, I tried with lineage and arrowos and I don't believe the problem is with the roms.

Thanks to anyone to offers any suggestions, this is my first time attempting this, so don't assume I know anything, I just step by step tutorials and usually don't have problems like this.
