Hello,
Last year I installed android 9 and now I want to go back to flyme os, when I install it via twrp it says "cannot mount /custom", the installation process fails and know I have no OS (it boots straight to fastboot) I still can access recovery though.
Any help is appreciated.
Thank you.

I had rooted my phone with fastboot and installed android 5 with gapps, but it seems it isn't successful as whenever I try to update my phone it download the updates but doesn't install it. Whenever checked it will always show the same update available. During boot up in fastboot it says root possibility may lose, I had installed SU while flashing the device. They are many root softwares which work fine on bluestacks & not on my device. I had tried various boot loaders such as CMR & TWRP but all were unsuccessful in installation. Phone is getting hanged up & automatically restarting too much, Kindly please help me with these issues.
So im trying to root my oneplus 5 and i started off by using Lineage OS but i wasnt too happy with it and i liked Oxygen OS much better so i decided to go back to it and while doing so like an idiot i wiped everything in twrp including the storage with all my ROM files and the phone was bricked and after a long struggle i used the unbrick tool which is called MSM tool which installed oxygen 4.5.8 using some some Qualcomm mode or something and it booted and worked fine but ever since i wasnt able to download the oxygen 5.1.1 update through the phones update section, it reaches 100% and says signature verification failed and goes back to 5%. So i tried downloading the latest Open Beta from the OP site and tried local upgrade which said installation failed so i try installing it locally through the Oxygen Recovery but again Installation failed so i try unlocking the bootloader again and installing it through twrp and it just keeps showing the boot animation forever( i know people say be patient but i waited for 20 mins+). So i decided to use the unbrick tool again and now im stuck on the OOS 4.5.8 unable to update the phone.
I tried to flash the latest oreo through twrp several times and just tried flashing it through so many ways where none worked , even adb sideloading it worked till 47% and said installation failed and everytime this happens i have nothing left to do but use the tool and unbrick it again and this takes so much time as i have to unbrick and then do the first setup and then go to fastboot and unlock the bootloader and do the setup again and transfer the files and then install twrp and flash.
Nothing has worked so far
And now even when i go back to the 4.5.8 stock after unbricking for some reason it just doesnt connect to any wifi , it just says Connecting and then saved and then disabled and repeat, only my mobile data works.
I tried to flash lineage again but got an error 7 with it or something and im back to the stock unbricked state without wifi and all i can do is unlock bootloader and install twrp.
If anybody has any suggestions and can help me please do so immediately. I require my phone urgently and need to fix this fast.
Thank You !
(btw im in India and do local service centres fix such issues?)
Make sure you use newest twrp. And also flash firmware for 5.1.1

i am using the latest codeworkx twrp 3.2.1 and when should i flash firmware? can you just give the process i should do? stuck at 4.5.8 without wifi with twrp and unlocked bootloader
Wipe everything except internal storage, after that click format data and type "yes" to accept. Then download oos 5.1.0 firmware from here https://sourceforge.net/projects/cheeseburgerdumplings/files/15.1/cheeseburger/firmware/ and lineageos 15 (or any rom you want now), gapps and move all 3 packages to your phone. Flash firmware first and then reboot to recovery. Then flash rom or gapps and reboot
You have to flash the latest TWRP from twrp.me, then download the latest OxygenOS build. Reboot into TWRP, wipe data, cache, system and flash the latest build, then just go to wipe > format data, type "yes" and reboot
Lol man your OP5 is not bricked, if you can boot on TWRP, you can install all that you want
I advise to Format Data/Storage, Wipe everything and install xXx 10.7 (OOS Custom with a great Aroma installer), choose decrypted, it's better if you want swtich rom in the future AOSP > OOS > AOSP
bro i have same probleme after install any rom custom or official , always stuck on boot logo , any solution ?
no solution??
Its a shame.
7 years unlocking bootloaders, installing CWM or TWRP or Philz recovery, flashing rom after rom, not even one device bricked, and today, i messed up, i hope its not bad.
So the short version of what i did is that i flashed twrp.img trough and older version of twrp and now it wont boot into twrp, it says that it failed to verify the recovery image or something like that, and my laptop wont recognize the cellphone, the cellphone boots into the latest Havoc rom but without Gapps and without root because i did not install it beforehand, when in bootloader mode it just says that it could not recognize the device.
The long version is that i had Resurrection Remix, obviously an unlock bootloader, magisk etc... everything was fine until today that i tried to install Havoc, the installation went well but i found out that ambient display was not working, someone told me that the previous version of Havoc did not had that problem so i tried to flash it but it bootlooped for like 1hr, so i read that the version of TWRP provided by the OP was the way to get it to work, i downloaded the .img file and flashed it trough TWRP and tried to install Havoc again but i was stuck in a bootloop, so i flashed the latest Havoc build so i could download the latest version of twrp, i did not flash Gapps or Magisk because i was going to re flash the rom and then flash Gapps and magisk, so i downloaded TWRP and flashed trough TWRP and thats when the sh$& hit the fan, now it wont boot into TRWP and my laptop wont recognize the device, neither on android nor in bootloader mode.
So, thank you guys in advance for your help, tomorrow im going to try on a computer at my work and see if its my computer and if not, well, ill have to se what you geniuses come up with. thank you so much again.
Info:
Rom build number: opm6.171017.030.h1 or 20180811 android 8.1.0
TWRP: i started with 3.2.2-0 then i downgraded to 3.2.1-0 and the one that messed up everything was 3.2.3-0
By the way, I have a full twrp backup of when my phone was stock, (but no way to use it) T_T
I've messed everything up and now I'm devastated!
My S8 stucks at the very first screen (where it says: SAMSUNG GALAXY S8 - powered by android). It doesn't boot further this very specific screen. I have tried to update Magisk and Magisk Manager but only Magisk Manager seems to get updated successfully while the app suddenly says that the latest version of Magisk Manager required Magisk V19.XX hence I've tried to install it via TWRP. According to log screen, I've managed to install magisk via TWRP but after booting up, I opened Magisk Manager where it now says that Magisk isn't installed. I therefore boot into TWRP and tried to fix it since some apps of mine that required root access wasn't working anymore. So, I thought I must have lost root access. I once again boot into recovery, I uninstalled magisk and install an older version of magisk and magisk manager and also the no_verity patch. After that my Galaxy S8 won't boot up. It just stucks at the very first screen. My S8 (international version) is still on Nougat stock samsung firmware and I can enter TWRP but the phone remains freeze and stubbornly refused to boot up.
I'm quite devastated and I hope you guys can help me fix this issue!
Thank you!
Hi, well sorry if I am stating the obvious but I would format and install one of the many custom roms available...

Are there any solutions other than flashing a custom rom? Meanwhile, I have managed to flash Android 9 via ODIN and have TWRP installed but it won't boot up and stucks at the very first booting screens.
Any help would be appreciated!
Thanks!

Have you tried just flashing stock rom only to see if it boots up. You may have to do a clean install.
Problem sounds like you haven't decrypted phone and flashed no verity zip file.
You won't need to flash a custom rom to fix this.
As for magisk have a look through this very helpful guide for installs and troubleshooting.

I've managed to solve this issue by myself. But still, thank you so much! It's the thought that counts ? And yes, I've figured out that I haven't decrypt my S8. But everything is absolutely fine now and I feel extremely relieved. It took me 1 day to fix this major issue and I've encountered lots of difficulties while trying to fix this like bootloops, system won't boot up and managed to stuck at the very first booting screen again and the phone boot past the first booting screen and stucks at the second booting screen, and also bootloader error and stuffs like where realization hit me that I can't restore my nandroid backup while still on Nougat because after restoring it won't boot up. I therefore managed to flash Android 9 and twrp. My S8 is now on Android Pie with custom recovery and rooted (via Magisk).
==================LONG NOOB WARNING============================
Hi!
Recently I've just installed Lineage OS 18.1 on my phone
Phone: LG G2 (international[D802])
Current build is: lineage_d802_userdebug 11 RQ2A.210405 cd6fb8d05d ( lienage os 18.1 2021.04.29 Nightly )
So first I've switched from the original os (Android 5.0.2) the steps I've done:
1.: Rooted my phone via LG One-click Root what I found on the internet (https://www.dropbox.com/s/2shvozzbu29xjfu/LGG2-D802-OneClickRootRecoveryV1.1.zip?dl=0)
2.: installed TWRP recovery with TWRP manager (https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager&hl=en), (https://www.gregtwallace.com/lg-g2/g2-twrp/?version=3.3.1-0#download-section)
3: downloaded Lineage Os build 18.1 20210422 and BitGapps
4: Installed both of 'em.
After these, I used my phone and I was happy, (i switched the recovery to lineage as it came on screen I didn't know I'll need twrp in the future) but just as soon as the newer (my current) build came out it notified me, and I started downloading it through the built-in updater (settings-system-updater)
First, it appeared to installed normally, so I basically left it to do its thing, but it turned out it won't boot (Couldn't load android), so I tried to install it again with ADB via built-in lineage recovery, it said it was successful, however, it didn't load so I formated the data within the recovery, and it immediately booted into the system. Now comes the part which i need help in (i wrote all this down to get a better view of the problem), so after i booted into LOS i noticed, that the gapps are gone.
I thought ok, it is how it is, then let's try and install them. So i downloaded the minimal ADB and fastboot program which as far as i know is enough to do simple installs. So i fired it up, went into lineage recovery and clicked install update with ADB (or however it is called, can't remember that ), and i wrote in the console ' adb sideload <bitgappsxversioncan'tremember>.zip' and it started to install but got me with:
"finding update package...
verifying update package..
update package verification took 2.7 s (result 0) .
Installing update...
***********
BiTGapps R25 Installer
************
-installing toolbox
-mounting /system
!cannot mount. Aborting----
-unmountig partitions
! installation failed
E: Error in /sideload/package.zip (status 7)
"
I took my time to make sure it's the right version (it is arm as my device run by arm, and it is R as Android 11 so i think it is for my os)
I'Ve thought ok, then maybe i'M doing something wrong, so why not just wipe all and restart again?
I noticed i have no root permission, so i have to get one, now as i know (correct me please if i'm wrong) LG oneclick root is for Kitkat and lollipop and stock firmware (?), so i looked up the internet and saw that lineage has removed the super user (root) option from the developer and have to install and addon (su package) to readd it. i thought, aight' let's do it then, i downloaded it and tried again via sideload on adb and from internal storage too (addonsu-16.0-arm-signed.zip), but the result was similar to my previous attack with gapps except it said
"
installing su addon...
set_metadata: Error on lstat of "/system/etc/init/superuser.rc": too many symbolic links encountered
E: Error in /sideload/package.zip (status 7)
"
Apart from these Lineage runs great, except hbo go wont work for some reason (chromecast library cant be reached or so), but I'm okay with that, and a huge thank you to the developer for the os!!
so my questions are:
Either way:
-can I root it somehow to be able to install TWRP, and start everything over and get Gapps?
- Can I install Gapps somehow without reinstalling recovery?
-in the official TWRP app there's no d802, which one should i download, or even should I download any different model (like American or d800,d803, etc.)
Apart from the previous question is there a way to upgrade lineage without losing data? (i read somewhere that sideload should be my choice is it true?)
Thank you if you've read this far, if you know any solution for me please share with me, I'd be really grateful!
have a nice day!
