Error while flashing ROMs. - OnePlus 2 Q&A, Help & Troubleshooting

I've been trying to flash Nougat ROMS on my OnePlus 2. Every time I flash a new ROM, the process says "patching system unconditionally" and ends with
E:/ unknown error[log]
E:/ unknown error[log]
Then when I reboot, I get a boot loop and stays at the OnePlus logo.
I've tried different versions of TWRP. I've flashed both CM14 and RR14. Both showing the same error. Both original zip files showed Error 7 at first. I changed the updater-scripts in the META-INF folder and rezipped it. This solved Error 7. That is when this showed up "E:/ unknown error[log]".

It's not an error. It's informing you that the system image is getting patched with new ROM.

bootloop after flashing incorrect boot image

Hello. I have a XOLO Play Tegra Note 7.
A couple of days back I, in an attempt to flash a ROM that I downloaded from the NVIDIA website, I accidentally flashed a boot file from a CyanogenMod image that I downloaded for another purpose. Now, I'm neither able to flash the correct boot image (it is not recognised by adb) nor apply update through bootloader recovery (it says E:footer is wrong, E:signature verification failed). All that's happening is that its bootlooping.

error flashing Zip files

I flashed a few bootloader animations and later it stopped working. Whenever I try to flash them through flashify, it shows this error:
In case the image doesn't show, I uploaded it to imgur.

Have you tried flashing them directly in TWRP manually?

Bricked P9 Lite?

Hello,
I have a problem that I can flash TWRP wich works fine. I can go to fastboot. But however I am not able to install any ROMs. Tried Lineage 14.1 and Stock rom.
I tried to flash stock recovery and tried to flash it back by "dload" method - error "Package firmware is not compatible" and when I tried to flash Lineage 14.1, everything seemed fine until boot logo where I was stuck for half an hour before I gave up. Also I am not sure but I think I havent managed to root my phone - tested with "adb shell su" wich gives error messages.'
Even tried hisuite recovery but it said that my phone is not supported.
Tried erecovery wich said "Getting package info failed"
I also can enter stock recovery
Im also getting
Failed to mount /vendor (invalid argument) in olddroid TWRP
and when trying to flash system I get FAILED (remote: sparse flash write failure)
So basically only thing I can do is be in TWRP without root, fastboot and stock recovery.
I have european VNS-21. Used to have stock nougat with EMUI 5.0
Any ideas how to get back any kind of rom?

@[email protected]@[email protected] TWRP - i/o error

Yesterday I've tried to setup Lineage 14.1 on my Galaxy S4 GT-I9505 and in process of firmware updating TWRP displayed a message:
"error opening: 'data/misc/profiles/cur/0/foreign-dex/@[email protected]@[email protected]' (i/o error)"
After firmware update, I installed several updates and each time TWRP had been displayed that message.
After that, I proceed this path in total commander and didn't find this file (only few others), same time, TWRP file manager showed it, but not allowed delete or move it, even change permission, as same as copy to somewhere.
Could some one say, what is it mean this message (is it serious problem?) and why TWRP couldn't do anything with this file?

I haven't been able to install any custom ROM, please help me! :(

I've tried to install some custom ROMS and always I have problem, both for ROMS with extension .zip (with TWRP) and for extension .img(with ADB). Anyway I always fail. Even to make backups with TWRP, also to wipe cache. For all always there an error, I don't understand why. In the past I had install Samsung ROMs without problem, but in Huawei have been an infernal experience, all is so much hard.
-When I try to wipe cache, appears an error that says
"Unable to wipe cache.
Unable to wipe /cache."
-When tryng to flash stock recovery from TWRP appears an error that says
"Size of image is larger than target device"
-When tryng to make BACKUP with TWRP appears an error saying
"Can not create '/external_sd/TWRP/BACKUPS/<<serialnumber>>/<<actuallydate>>' folder (Permission denied).
Failed to make backup folder."
-When trying to flash a .zip ROM from TWRP says
"Updater process ended with ERROR: 7
Error installing zip file 'external_sd/LineageOS15.1-Hi6250-08-18-2018.zip'
When trying to flash GSI ROM(extension .img) with ADB, after "writing 'system' 1/4..." says
"FAILED (remote: sparse flash write failure)
finished. total time: 19.889s"
Those are my problems trying to flash anything :/
My phone is Huawei P9 lite 2017 PRA-LX3 with Android 8.0
PLEASE HELP ME!
You are trying to install a P8 lite(2017) rom on your p8 Lite.
