Hello!
As far as I understand (with my reverse engineering investigations), it looks like the new preloader from the iodéos 7.3 spflash image I downloaded on my phone with “Format All + Download” is possibly different from the previously working preloader that was on my phone when I received it. The new preloader could be the cause of the issue because it would not be able to correctly perform DRAM initialization. My AI model told me the logs found on the backed up expdb partition could not have been produced by the current preloaders I have (either the one from iodé os or lunar os). What AIs say should always be checked.
Does anyone have a working BraX3 of the new batch and could extract its preloader (for example with the readback function of SP Flash Tool or with the mtk ro 0x0 0x100000 preloader.bin --loader DA_BR.bin --parttype=boot1 command of mtkclient using DA_BR.bin from any of the BraX3 spflash firmwares, or this patched one) and send it to me to compare ? I have restored most partitions from my backup and dram initialization still fails (but I lack the backup of the preloader).
Thank you!
