Hi All,
Having some issues with my V30 H930.
I've unlocked the bootloader, installed TWRP and had Pixel Experience running nicely.
Last night I decided to change the ROM to Potato Open Sauce Project, so I rebooted to recovery, performed a factory reset and then proceeded to install the latest POSP ROM and OpenGapps Mini.
After installing, I tried to reboot to system but instead, it just booted back into TWRP.
I then attempted to factory reset and install both zip's again. Same result, could only boot back to TWRP (No fastboot or normal boot).
Now nothing will install on the phone.
I found several threads that advise to try repairing Data or to change Data's format to F2Fs then EXT4. When trying this, I get the following messages:
Failed to mount '/system' (No such device)
Failed to mount '/data' (Device or resource busy)
Failed to mount '/cache' (No such device)
Unable to mount storage
I have tried rebooting to recovery multiple times and doesn't help.
Does anyone know what the best way to resolve this is?
I was considering letting the battery die and then try to boot into fastboot and attempted to reinstall stock software with LG UP but not sure if that will work or not. The phone is currently on 100% battery, so it'll be a while before I can test this.

Hi all
Dad's I9300 (international) started making problems booting up a week ago (sometimes it did and sometimes it didn't for a few hours). Begged him to bring it in for me to backup. Of course he didn't and today the device refused to boot permanently. It simply gets stuck on the logo screen.
When boot into recovery I got lots of E: failed to mount /cache. After wiping the cache and rebooting into recovery I now get only E: failed to mount /system (see attached image).
Download mode also seems to be working.
Device is 4.1.2 with stock ROM and stock recovery.
The main concern here is to recover all personal data. After that, I don't care if the device gets bricked. I searched the web and came up with two possible solutions:
1) Reflashing the same stock ROM I flashed a while ago (hoping that what I have stored on my PC is what is actually flashed on the device.....), and not wiping the data. As I understand, flashing a stock ROM without wiping data shouldn't cause the device not to boot.
2) Flash PhilZ Touch 6 Recovery using Odin and use Aroma file browsing to copy internal memory files (pics, mp3, WhatsApp data, etc.) to an external SD and then start messing around with the phone. (as described here)
What's my best option here? It sounds to me that the second one is better, but I'm not familiar with flashing a recovery and possible consequences.
Can someone kindly advise? I'll greatly appreciate any word of wisdom...
Solved.
Before I ask, I have very limited knowledge of ADB and have been using "interface" like programs like WugFresh for all my Android root/flashing/pushing.
This is on my Nexus 6
I wanted a custom ROM. I settled on Cyanogenmod. Somewhere during the process I messed up and had to start over. I must have unchecked/checked a box I should/shouldn't have because I kept getting the E: Unable to mount Storage and cannot see my phone in Windows Explorer as an MTP device. So I did a complete factory reset, flashed the stock ROM and it seemed to resolve the error. I then flashed CM 12.1 again and started the daunting process of reconfiguring my phone. I chose not to restore my backup because I wasn't sure if the error would come back too (n00bie, I know). Then I also made the mistake of allowing the OTA CM update. Well I lost root as a result. So I attempted to root again but it got stuck at the boot logo. In a panic I booted into TWRP and dirty flashed CM 12.1 using ADB sideload. All was good, I re-rooted again successfully, but now I am getting the same E: Unable to mount Storage error again.
So I guess my question is, how do I do a backup so I do not have to reconfigure everything again and still be able to flash the stock ROM. Or do I even need to flash the stock ROM again, can I do a factory reset and flash CM 12.1 or will my error not be resolved?
Thanks in advance.
Hi all,
I have Samsung A5 2016 and I tried to update my phone through latest Naugat official firmware using by Odin however it turned out something wrong. My first problem is when I enter the boot screen, ''installing update'' screen pops up and then ''no comment screen'' afterward. Second problem is that boot screen shows an error says E: failed to find /misc partition. I've read tons of post however I couldn't figure this out.
I would greatly appreciate it if you could help me.
Thank you & Best!

Anybody know how to deal with the E: failed to find /misc partition? I saw this come up on my SM-J700T after I tried to flash TWRP. The flash passed but TWRP was not successfully installed. Probably because I did not prevent reboot and reboot in a proper way . But now I have been all around the barn trying to recover and eventually get twrp and root. I flashed several stock roms with lots of errors and finally got the phone running with Nougat 7.1.1 but the E: failed to find /misc partition error remained on the phone all the while. I was unable to use Odin to re-partition due to errors and have been trying to figure out how to use adb, also with errors (yesterday I launch "abd devices" and get a listing for my device (I think- it is not properly identified) and it lists the device properly, today it lists the same device as unauthorized. So what I really would like to do is completely wipe the phone and start fresh but I only have access to the stock bootloader which allows cache wipe and data wipe- factory reset, which does not wipe the Missing partition. So 1)completely wipe phone 2)install twrp 3)root
Hi guys,
Having a bad time setting up my S7 Edge (international model).
End goal is to have it rooted with a Lineage OS ROM.
Successfully flashed TWRP (3.1.1.0) using Odin3 (v3.12) and had no issues booting into TWRP and looking around.
Issues began when I tried to wipe the internal storage in preparation for a new ROM; I got errors along the lines of "unable to mount /data" invalid directory, "unable to mount /system" etc, and the wipe would fail.
Following another user's guide I formatted my /data partition to ExFat (plan was to then format it back to Fat4, which supposedly fixes the issue), however this froze the phone. I was able to reboot it after leaving it a few hours, however now the phone just freezes on the TWRP logo when I try boot into recovery.
I have reflashed TWRP to no avail.
From what I've read online, flashing a new ROM via Odin might recreate all required partitions (namely /data) ? Issue with this is I can only find .zip, not .tar ROM's as required by Odin.
Have I just turned my phone into a brick ?
Any suggestions on what to do next would be greatly appreciated !
Many thanks,
Pron
Hi, I'm new and have a problem of my own doing.
I loaded the recovery mode and attempted to load TWRP without knowing how to activate Fastboot. Unfortunately, I had wiped the cache partition and rebooted the phone.
It resulted in kicking itself into recovery after a failed boot-up into android, as string of E: can't mount /cache showed. I tried to wipe data/facctory reset and try again but I'm stuck.
If anyone has a possible solution/suggestion, I'm open to do it.
