Hi

thanks for the new tips i will give that erase method a go and flashing the IMG files one by one as you suggested and will update on that either way i think that is the one method i have not tried yet because all the instructions i followed was based either on fastboot and using the flashall command or the Qfil under EDL mode and thinking about it if the old files are still on the phone might be why it wont flash the new ones

you asked how the issue started and reason for flashing well the phone got stuck on the Asus Logo when powering the phone on it would flash up saying powered by android then the asus logo will apear and its stuck there

the next process was to do what i would do with any phone is try to do a recovery / factory reset by using the volume down and power buttons but phone doesnt respond so tried the volume up and power and just brings me into CSC fastboot mode i tried holding volume button down press power and release power when phone vibtates but kept holding volume nothing happened ans then i tried holding both volume buttons plus power no response so either the phone was setup in a way that the recovery options was never there or some how the phone got corrupted i dont know because one minute it was working as normal and next its the Asus logo

tho i should say the phone at times had got a little warm usually because the phone is a bit of a work horse meaning its always being used for video recording and uploading and other work related tasks

all that i have tried has been the fastboot options such as being able to detect the phone via the fastboot devices command and that does bring up the serial number and have tried to use the flashall command per what the instructions said it would appear its doing something then suddenly it will give up the error cannot flashed in lock state oh yes and did run a command that bring up info about the bootloader and it states the bootloader unlocked is set to false

then i have tried the Qfil software and in most cases it had always given errors such as sahara errors and too many XML in string table max was supposed to be 8000 but it was something like 8900

the interesting thing to note is that i had downloaded several firmwares because i was not sure of the exact firmware on the phone so i was left guessing at the selection that was given so i tried working with a more up to date the interesting part about that is when trying in fastboot the error was different compared to the last 2 firmwares i tried the first 3 i tried i would get almost instantly a write protected error where as the last 2 firmwares will bring up the cannot falsh in locked state error so it seems to me the newer versions of the firmware the phone is rejecting where as the last 2 firmwares the phone seems to respond to them and fastboot might accept them if the bootloader is unlocked

back to Qfil i tried researching the various errors that displaed mainly the too many XML in string table and came across a post on XDA regarding Flashone 2.0 it has a Qfil flasher within its folders and i have tried that and that is the one that gave me the most action and that is what i discussed above when it copies over the IMG files it would stop and error at certian percentages such as system.bin 85% another image maybe 20% i will try and copy a snippet of the log on here so you can see for your self and this version of the Qfil was the first time i ever seen the blue progress bar move

in your reply you mentioned about using an update file i assume is where you mentioned the memory card i cant do the memory card option just yet because i cant get access to memor card have to rely on stores near home and dont have in stock size i need i dont want to go out and buy a huge size as i rarely ever use memor cards .. and i do believe one of the firmwares i download was actually an update rather than a folder full of files and because i cannot access any of the options under hardware key on start up im in doubt that accessing the memory card to recover would work anyway

now looking at the website you gave with the instructions i believe the memory card option as mentioned may not work because the volume up plus power puts the phone into CSC fastboot mode only

second option is install via ADB Sideload but the requirements is the phone needs to have its developer options enabled and thats disabled on this phone

as for the question about the bootloader yes have tried those commands you mentioned doesnt work and any research on unlocking bootloader for this model seems to always bring me back to the same options by using the APK file from Asus or the ADB commands

by the way here is the list of firmwares i have tried not sure if the info will help but its here anyway just in case Note the last 2 firmwares are the ones i mentioned above that seems to make the phone respond differently compared to the first ones

Asus_Zenfone_5_Lite_ZC600KL_630_14.0400_1808.057_20180903_CMD

WW__ZC600KL(630)_14.0400.1801.021_20180204_Phone-user

the last firmware on the list is the one i believe is the original version thats installed on the phone as i managed to pull the version.bin off of the device and open the bin file using Hex and this was what i found

here is a quick snippet from the text document of the error that i mentioned about when it stops copying after a certain percentage

this is one of the erorrs i mentioned 12:31:43: DEBUG: Response was 'NAK'
