Hello!
If you have a BraX3 of the new batch, as far as I understand (I may be wrong but I would like to check), it possibly has a different preloader than the previous batch. The official spflash iodéos firmware (at least until version 7.6) seems to have a preloader (with sha256sum 20304da386e66379eab9805b81372319bd5127c6493294d5b2fe21369002fdfc) that only works on the previous batch and cannot successfully perform dram initialization on the new one. Avoid flashing this preloader to a BraX3 device of the new batch to be sure you do not brick it as I did. If you have a backup, it should still be possible to restore it with mtkclient. I don’t have any backup of the preloader, but could someone please extract the preloader from a phone of the new batch and send it to me to check if it is indeed different and to help me unbrick my device, that would be very kind! Don’t send your answer in this thread, use the dedicated thread below:
Thank you!
