[Please help] SPFT Write Memory doesn't work
[Please help] SPFT Write Memory doesn't work
(01-06-2021, 09:05 AM)Ga Gu Hi, it's me again. My phone is Meizu M5 Note (M1621).
This time the preloader partition is changed because I tried to flash another version of official firmware while trying to unlock the bootloader.
(01-06-2021, 09:05 AM)Ga Gu If I try to download the preloader using SP Flash Tool, it shows error STATUS_SEC_DL_FORBIDDEN (0xc0020004).
(01-06-2021, 12:31 PM)X3non does this mean that you were able to successfully flash preloader from this official firmware?So here's what happened.
(01-06-2021, 12:31 PM)X3non which preloader are you referring to here?After he phone was bricked, I restored almost all partitions to what I backed up before I made my first thread in this forum.
(01-06-2021, 03:08 PM)Ga Gu After he phone was bricked, I restored almost all partitions to what I backed up before I made my first thread in this forum.
And I'm trying to restore the preloader of my first backup, which is of the official firmware version 6.7.7.1.
(01-06-2021, 03:37 PM)hovatek 1. Are you able to do a readback of any partition?Yes. In fact, I just did a readback of all partitions (except userdata), and did a comparison to my full backup.
(01-06-2021, 03:37 PM)hovatek 2. What's the outcome of Format all + DownloadWhat if I format a partition and I can't write data again?
(01-06-2021, 03:37 PM)hovatek 3. Have you tried flashing the same v7 rom that bricked the phone to see if you get the same error?Just tried. The same error.

What if it goes wrong?
Am I guaranteed to be able to write any data into any partition?
Write memory feature has failed so far.
Quote:3. Do not format a Secure Boot MTK device: If you’re lucky enough to get a DA file for your model then the last thing you’ll want to do is Format. Once you do, the DA file that once worked will stop working, causing tools to request for an Authentication file.

(03-06-2021, 11:32 AM)hovatek This is a valid concern. While in most cases, a format should be avoided; in some situations, its the way to go so far you know what you're doing. The Auth bypass tweak knocks out the need for an auth file.It sounds a good idea to try flashing v7 rom using download only.
You could try the v7 rom using download only.

(04-06-2021, 09:55 AM)Ga Gu But I have some question with flashing stock rom of this phone.
The scatter file's format is unusual and can't be recognized by SPFT, so I have to choose manually which partitions to flash.
(04-06-2021, 09:55 AM)Ga Gu But how do I deal with the file file_contexts.bin? Do I ignore it?
