Hello everyone,

I recently got an Alcatel 1S 5028D and I tried to install a GSI rom on it. The ROM worked fine but my IMEI/baseband was wiped and I had no SIM card connectivity, when I tried to fix that I stupidly flashed the wrong vbmeta file which is now causing an infinite boot loop and it won't even enter recovery or fastboot.

Looking for solutions I found this forum and the SP flash tool which should work with my phone (Mediatek MT6762D Helio P22) and I wanted to use the tool to flash the blank vbmeta file and go on from there, however the tool always returns the same error: "STATUS BROM CMD START FAIL" which means I need a custom DA/auth file.

Is anyone so kind to help me out a bit and provide the correct files for my phone?

Thank you very much in advance and all the best!

P.S. I also posted this thread in quick questions sections, but I'm unsure if that's the right place so I'm also posting here, hope that's okay.

Thanks for your answer, however I don't think my chipset is supported by the bypass (Mediatek MT6762).

I gave it a try anyway, it detected the port but it hangs at that point and goes no further... any other ideas?

I attached the CMD image below.

I ran it using PowerShell and got a different result, still an error though.

Screenshot attached.

Thank you very much for the fast replies!

edit: I googled the error a bit and it seems to be related to the usb libraries, I tried reinstalling the usb filter multiple times + restarting my laptop but it didn't help.

Update: I copied the DLL to the directories it said in the error and I successfully disabled the protection!

However, after trying to flash the VBMETA file I get the following error: ERROR: STATUS_PRELOADER_INVALID 0xC0030004

Do you think this is caused by the wrong scatter file or should I find a preloader and flash it as well?

Thanks again

you need to include preloader when flashing

Thank you for all your help.

However, I can't seem to find the matching preloader/scatter file for my model of the phone.

Would you be so kind to tell me where I can download the matching firmware for my device?

you could try using alcatel mobile upgrade S tool; if it can detect your device then maybe it could download stock firmware from where you can grab preloader
OR you can try doing a backup using a hardware dongle tool e.g cm2 dongle, at least they don't require preloader in order for their backup feature to work
