Cant make use of AFT
I am unable to select the downloaded .raw file in AFT.
the only supported formats are .img or .zip
how can I flash the stock .raw file.
nor the SD DOWNLOAD in Droidboot mode recognizes this raw.file
I have tried to download it more than 4 times thinking that file might have currupt. but same result every time.
Please help
Edit:
anyways I got to learn how to select the file but now when I connect my device to PC in droidboot mode, error message pops asking to close AFT. I can Ignore the error msg to keep it running but No device is being detected in AFT.
That error comes every time I connect or remove device from PC.

4. All the Tools required to flash the firmwares and study of methods to do so. I used WIN-XP and tools installed on the same. All Drivers installed successfully device recognizing and able to use fastboot and adb.
5.Current device status: To flash UL-ASUS_T00I-WW-6.6.3.0_user.zip
I tried following methods :

bro u got any fix?
The links in the OP are absolute poison!
Are the files available from any other source?
Where can I find ASUS_BUNDLE.ZIP which droidboot requires?
Hello ! I've tried to unlock bootloader at first and succeeded in that when i was on the lollipop . Unlocking is done by the unlock tool provided by the ASUS Officials.
Then i flashed the cynogen 12.1 unofficial via a boot.img , atwrp v3.img & a system.img.
Everything was fine until i needed to revert back to stock firmware.
And also everytime when i try to boot into recovery via Power & volume (-) button , it boots into system.
I used "adb reboot recovery" to boot into twrp recovery .
So, to revert back i saw a method in which we flash a raw firmware , and i downloaded a 4.0.3 for Asus Zenfone 4.
But after flashing it , the bootloader i unlocked , got locked by itself (means i can open droid boot but cannot modify boot and recovery partition via "fastboot flash boot boot.img" & "fastboot flash recovery recovery.img" ).
I can only flash system via " fastboot flash system system.img".
I tried to unlock it on Jelly Bean but no success.
Also i tried updating the firmawre via OTA and flashing zip in recovery mode but i was not able to boot into recovery mode, even with "adb reboot recovery".
It always ends up with a reboot , then booting into a 'Android logo for 200 to 300 millisec' , & then boot into system.
Then i found a KitKat firmware raw file , but when i flashed it via AFT 1.0.0.0 , it always gives error "no space left for flashing modem binary".
I tried "fastboot erase data" ,"fastboot erase userdata" ,"fastboot erase cache" , & "fastboot erase system" , but ended up with stock rom with no modem binary.
So , i tried to unlock the bootloader again by the "unlock tool" provided by ASUS , but even after connected to a high speed Wifi , It gives connection error and rest of the other things are working fine like browser etc.
I also tried to flash the modem.zip inside the stock firmware zip via fastboot as : "fastboot flash update modem.zip. It has flashed the zip but still no modem binary.
Then i tried to flash the bin file inside the modem.zip as : fastboot flash radio radio_firmware.bin and it gives error : No space left for flashing modem binary.
Now i have a bootloader (locked) but no recovery and a stock firmware with no modem binary.

you may download and install the below LGUP, then replace the files in the lgup forlder in your program files with the one in "LGUP_to be copied into LGUP folder", then run LGUP you'll be able to crossflash to your European kdz again.

Having trouble using LGUP

I have korean version V40 (30f).
I have destroyed my firmware by flashing wrong things in wrong partitions.
As an last ditch effort, i flashed 30c (dont know which version, probably pie) adb, boot, dtbo and laf files to get into download mode, so i could get into download mode again.
But in download mode, when i try to flash the original kdz (Android Q), following error occurs, which i successfully flashed before this.
I tried different 30f kdz, but error shows up i only could use skt_kr version
Any idea why? Should i download Pie or Oreo version of it?
I have to wait 24 hours since i already exceeded download quota of the day.
SUCCESS!
For anyone having problem with LGUP
Use this, it bypass crossflash protection.

Maybe you can try older version of SPflash.
I've been trying to flash stock ROM using .zip fastboot files from
Xiaomi Firmware Updater
The ultimate script that provides firmware packages for Xiaomi devices.
xiaomifirmwareupdater.com
They all seem to come in a payload format, which is not recognised by Xiaomi Flash Tool. What am I doing wrong?
Ok, I've figured it out. Here you can find the latest global ROM and Xiaomi Flash Tool
https://c.mi.com/in/miuidownload/detail?guide=2
Fasboot drivers can be downloaded from here
http://bigota.d.miui.com/tools/xiaomi_usb_driver.rar
This seems to be the cleanest way of doing it
