Hi I have an LG Optimus 2x SU660 and I am having a problem on upgrading it.
It don't have a adb boot-loader so I can flash IMG files to it.
Is there a guide so I can flash IMG files using nvflash? Or some one who know how to do it.
Thanks.
It is possible to use fastboot, but it's more awkward than other phones.
The thing with NVFlash is you need to be sure of your partition layout, NVFlash uses a number to identify which partition to write the .img too, if you don't know what the numbers are, you'll have some difficulty.
Thank you. I am also unable to access the fastboot.
I think its because I used LG-P993 rom that is compatible with SU660.
Never heard of the P993 before, but looked it up and it appears to be another variant of the Optimus 2X. Great, that'll confuse people.
To use fastboot you have to wipe your boot partition, if you have to ask, then I don't recommend it.
What might be best is if you can get someone to make a NAND backup of a stock SU660 and then you restore it.
Can you still get into (custom) recovery? If so then I don't see why you couldn't DD the image files, you can get the partition layout from /etc/recovery.fstab
I am now stuck again on fastboot. any fix can you recommend?
Oh bloody hell, what have you gone and done?
If (as I'm assuming) you've got into fastboot, then the best thing you can do is get a recovery.img and use: fastboot boot recovery.img, at which point you can flash something.
Did fastboot flash recovery c:/recovery.img but still it won't boot.
Don't worry because I can return it to its original state by flashing the old nvflash rom.
Of course it wont boot, you've wiped your boot partition remember
You will now have to tell it to boot from something, so as above, try: fastboot boot c:\recovery.img and you should be in recovery. Now from there you can flash a .zip (which will replace your missing boot partition) or restore a backup.
OR
If you have the right bootimage handy, you can use fastboot boot c:\boot.img and the phone will fire up, after that you need to use DD to permantly install the boot image you booted.
That you do from ADB shell or the terminal: dd if=/sdcard/boot.img of=/dev/block/mmcblk0pX (where X is the boot partition)
what is dd?

Sir may i requrest for your YM id?
If I knew what a YM ID was I'd tell you lol
dd is basically a *nix copy command, did you not use it to wipe the boot partition?
Yahoo Messenger Id.
No sir.
Oooh there's something I've not used in a while!

guys should i use the mi flashtool and flash the fastboot stock rom ?
The miflash only works with the original partitions. Try to change the partitions to original and late try use the fast boot. If you cant acces to the storage, use adb to push your zip.
This tutorial can help you:

Hey guys, i have a problem with the K20 Pro, i tried a gps module from magisk but it didn't work properly and now when i try to format data, factory reset this error appears: "Failed to mount /persist" (Invalid argoument). How can i fix this? I Was on EU Android Q Rom. I Can still boot up but things as Pop up camera are buggy
I think if someone with TWRP do a Backup of persist and upload somewhere for me i can back it up from twrp!

Fix: Just extract persist.img from your fastboot rom then use LR.Team TWRP to flash it in the persist partition after that when you boot to system open the camera app several times until a message apperars to calibrate, tick on it and you will see a popup message tell calibration successful.
Done.
i've managed to fix the problem with persist partition
i used persist.img form stock 10.3.3 global fastboot rom , and copied it to sdcard. then did the adb shell command with (dd if=/sdcard/perist.img of=/dev/block/"add here persist partition dir")
worked and my device now is working like a charm..

I read my computer partitions. After finding the number of the block that corresponds to my team, copy the persist of the rom stock to my internal memory in twrp and then flash with your command and add my block.
in my case note 10 pro (sweet)
dd if=/sdcard/persist.img of=/dev/block/sdf7
VERY CAREFUL NOT TO USE THIS COMMAND ON ANOTHER computer. each person must read the exact block that corresponds to your mobile reference.
I guess your problem is more of hardware issue ,but have to test to know.
I come to this conclusion because magisk does not modify partitions nor system files , I would start with a clean fastboot flash of the phone (be careful of the lock checkbox).
Then judge from there , if phone still presents anomalies then my first assumption is true.
Hi. This afternoon I tried to install the dirty unicorn rom. Unlock bootloader and flashed TWRP successfully. Then I tried to flash "Pie Firmware & Vendor" because it had realmeUI no ColorOs. The problem is that now I can not do anything with the mobile. It starts directly in TWRP. I have tried to flash a stock rom (CN) but it doesn't work. I think it is a problem with the partitions, for example if I try to clean cache / dalvik etc I receive these messages.
- Failed to mount '/data'
-Falied to wipe dalvik.
I have read many threads, but I cannot find a solution.
I saw this video,- [FIXED] Unable to mount /data or /system error- on youtube (sorry, i cant post URL yet) where even if it is another phone, it presents the same problem as me, but when I try to repair data I receive a failure (Error 8, unable to repair data) and I don't know what else I can do.
I hope you can help me .
Thank you!

Hi,I cannot pass files from my pc to the device, when I connect it, it is detected but it does not allow me to insert any rom.
Any other way to pass it?
Hi. I have managed to solve the problem that I had when wipe. I have changed "Data" format first to FAT and then back to EXT4.
But I still can't get past TWRP. Now if I try to start the TWRP system, it says that there is no OS installed.
Tried to flash ozip using SIDELOAD, but it gives me an error. I can flash dirty unicorns this way (for example), which also doesn't fix anything.

Hi. ok, after a whole afternoon struggling, i have found that i cannot flash .ozip from twrp, so i have transformed a rom .ozip into .zip. I have tried to flash using SIDELOAD but it gives me an error. I have tried to flash D.U rom the same way and there has been no error but it still gets caught on the loading screen. I don't know how to flash the realme rom, I can't fix anything, I'm really desperate
THANKS
What twrp are you using?
mauronofrio's last version -13 , orangefox R 10.1 and skyhawk 2.2 can decrypt and flash ozips.
Try also to put files to flash in a usb memory, change storage in twrp mount option and try to flash from usb.
If you flash aosp rom, try aosip 10, and used it and works well. and after flash it format data.

Hello, I just installed TWRP v13 and wipe everything (data, system, vendor ...).
I have tried to install rom stock by fastboot but still it doesn't fix anything.
I have also tried to install AOSP by slideload and nothing is solved either. I have to buy a usb adapter this afternoon, to connect and test it this way, but for the moment, I still have no solution. Thank you, I will keep reporting!
I definitely don't know what to do. Change TWRP for Orange fox, and I have tried to install a stock rom, I have tried downloading the latest official rom from here (Realme UI), https://www.realme.com/cn/support/software-update, but when flashing it gives me an error "Update process ended with error: 7. Are you installing onto the correct device?" (I'm sure I'm downloading the proper CN version).
I have tried to flash a previous rom that I downloaded from here (color OS 6.1) https://www.xda-developers.com/andr...2-pro-android-software-update-download-links/ and it seems to be successful, but it gives two failures at the end
1. Failed to mount / dev / block / bootdevice / by-name / userdata at / data: Device or resource busy.
2.Failed to unmount / data: device or resource busy.
The phone is locked in the startup image.
i am facing the same problem
twrp 3.4 is no longer able to unlock partition,
is there any solution
what to do ?
i have the same problem. i bricked my device and stuck at twrp.. every time i try to flash the latest official update from realme i get this error : Failed to mount / dev / block / bootdevice / by-name / userdata at / data: Device or resource busy."
i dont know how to fix it.. my bootloader is unlock.
i am stuck on bootloop and twrp.. any ideas how to fix it?
I have two ways that probably will fix your issues .
The first one is much more faster and I recommend you to try it first .
Boot into bootloder mode (fastboot mode)
Open cmd and type fastboot -w .(THIS WILL WIPE YOU INTERNAL STORAGE )
boot to recovery .
Wipe cache, dalvik-cache,system,data .
Format data .
Reboot to recovery (Use the recovery boot option, choose recovery) it will ask you if you sure to reboot as no rom is installed ,swipe yes,or something similar.
Flash ozip if you are on OrangeFox or unofficial twrp ,if you on official twrp that does not support ozip , you must use a zip stock rom .
Format data .(if have a error reboot into recovery and then format data again)
Boot to the rom .
If it does not solve you issue I recommend to flash stock rom with fastboot commends .
You can find the files needed in this thread https://forum.xda-developers.com/re...ock-fastboot-flashable-images-realme-t4003107 .
Choose the files for you phone version EU,IN,CN .
This is a color os and not realme ui . You can make your own realme ui version but this will work just fine .You can flash after a realme ui version ozip on recovery .
Open cmd on the folder of the download files .
Write without the quote mark and press enter "fastboot -w && fastboot erase system && fastboot flash boot boot.img && fastboot flash vbmeta vbmeta.img && fastboot flash dtbo dtbo.img && fastboot flash system system.img && fastboot reboot"
After this your phone should boot into color os version.
If you need help please write and I try to help you .
JUST DO NOT TRY TO RELOCK YOUR BOOTLODER, THIS WILL BRICK YOU PHONE .

I am just new to this flashing custom roms or firmware and twrp also. And dumb enough to not back it up.
I wanted to install arrow os in my phone. When I was about to wipe data, cache and dalvik, I accidentally checked metadata also and wiped. Then problems created more problems.
problems right now:
I cant put a file in my storage
Internal Storage is just blank on my pc
No OS
TWRP on both slots
please help me i really needed help and knowledge about it
I hope the attachment helps
EDIT--
Solutions to my problems:
WHEN you softbrick your phone and you only have fastboot and nothing else
Thanks to this guy..
SOLUTION: download your original firmware but choose the fastboot one and not recovery after download just unzip. Double click flash_all.bat and its back to square one.
WHEN you dont know how to flash or the file you have is .img
SOLUTION: find a guide in xda because apparently you can install a .img file in "fastbootd" mode
the guides here: https://forum.xda-developers.com/t/...sues-all-without-any-custom-recovery.4337099/
COMMENT: not the usual thats what on top of youtube search.
WHEN you see errors in twrp/orangefox recovery you might get panic and search for solution.
COMMENT: try to find and use a solution that doesnt delete something first. In my experience it got bricked even more.
Thanks to the people who commented back on my post and helping me get to know what to do next.
Try putting the stock ROM on a SD card or usb (if you have a dongle).

SD card that you put on beside the sim? if yes
Do I download stock ROM in official website? Cus I dont have 1 right now
then flashing it there by using twrp? is that how its gonna run? because i really dont wanna assume and create another problem
Try flashing this stock ROM (global) from a SD card, in TWRP. It's a recovery package, so you can install it as any zip.
Also, can you boot into fastboot/bootloader from TWRP?
Plus, where did you get the ArrowOS image? There are no builds, official or not.

A12 shouldn't be a problem.
Probably you should flash another vbmeta.img.

fastboot boot {recovery.img}
and then [Advanced]>[Install Recovery Ramdisk].
