Thank you for further explaining this and uploading your SD image! It was a great help! Working nice once again WiFi and USB not crashing! SDCard Boot directions for Sony PRS-T1 Copy contents of https://discord.com/channels/8092057...07186154438686 to root of SDCard folder Copy uboot_new.bin https://discord.com/channels/8092057...33364454834197 to Rupor Rescue SD Card, along with the other files that are already there… SD Card Layout Code:

I have two broken T1 readers. One gets stuck when 'Opening Book' hits 100%. Holding Home/Menu won't load rupor-rescue from SD either.
I was hoping to try this method, but there is little detail on the hardware aspect. I get that the OP wired directly to the circuit board, but the only detail I see is "USB-serial converter (3.3V voltage)". Can anyone tell me what this is or provide a link to this connector and/or what wire colors get connected to which solder points? |

IMHO, it's not worth the hassle. It would be better to just get a new Reader to replace the Sony.

We have a working T1, two dead T1's and a working T2.
Of the two dead units, one doesn't connect to a USB so it can't even be charged, but the other was my screw up... I was restoring the firmware because the dictionary was really laggy, my computer saw an 'unformatted drive', asked if I wanted to format it and I clicked yes before even realizing what I had done and it bricked the unit. It won't even boot an SD with rupor-rescue. The unit is otherwise okay, so this seems like my last option to pull it off. |

Hello jpa, thank you for your welding method,
I am using the method of ch340g usb to ttl, connected to putty but I don't know how to enter the recovery console, my prs t1 keeps restarting, flashing yellow, but the light of the memory card is not on, I suspect it cannot read the memory card. Do you have a similar method to get in, or swipe in the firmware, if you can reply to me, I will be very grateful! Here is what the putty interface displays: MMC read: dev # 2, block # 12288, count 5120 partition # 0 ... imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz ▒ U-Boot 2009.08 (Nov 14 2011 - 11:16:48) CPU: Freescale i.MX50 family 1.1V at 800 MHz mx50 pll1: 800MHz mx50 pll2: 400MHz mx50 pll3: 216MHz ipg clock : 66666666Hz ipg per clock : 66666666Hz uart clock : 24000000Hz ahb clock : 133333333Hz axi_a clock : 400000000Hz axi_b clock : 200000000Hz weim_clock : 100000000Hz ddr clock : 160000000Hz esdhc1 clock : 80000000Hz esdhc2 clock : 80000000Hz esdhc3 clock : 80000000Hz esdhc4 clock : 80000000Hz Board: MX50 ARM2 board Boot Reason: [POR] Boot Device: MMC I2C: ready DRAM: 256 MB MMC: FSL_ESDHC: 0, FSL_ESDHC: 1, FSL_ESDHC: 2 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz temperature 29 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz In: serial Out: serial Err: serial Net: got MAC address from IIM: 00:00:00:00:00:00 FEC0 Hit any key to stop autoboot: 0 MMC read: dev # 2, block # 12288, count 5120 partition # 0 ... imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x1 imx_esdhc.c bus_width 0x4 imx_esdhc.c bus_width 0x4 MMC set clock 50MHz autoscr - DEPRECATED - use "source" command instead base - print or set address offset bdinfo - print Board Info structure boot - boot default, i.e., run 'bootcmd' bootd - boot default, i.e., run 'bootcmd' bootm - boot application image from memory bootp - boot image via network using BOOTP/TFTP protocol cls - clear screen cmp - memory compare coninfo - print console devices and information cp - memory copy crc32 - checksum calculation dhcp - boot image via network using DHCP/TFTP protocol echo - echo args to console erase - erase FLASH memory ext2load- load binary file from a Ext2 filesystem ext2ls - list files in a directory (default /) fatinfo - print information about filesystem fatload - load binary file from a dos filesystem fatls - list files in a directory (default /) flinfo - print FLASH memory information go - start application at address 'addr' help - print online help i2c - I2C sub-system iminfo - print header information for application image imxtract- extract a part of a multi-image itest - return true/false on integer compare loadb - load binary file over serial line (kermit mode) loads - load S-Record file over serial line loady - load binary file over serial line (ymodem mode) loop - infinite loop on address range md - memory display mii - MII utility commands mm - memory modify (auto-incrementing address) mmc - MMC sub system mmcinfo - mmcinfo <dev num>-- display MMC info mtest - simple RAM read/write test mw - memory write (fill) nfs - boot image via network using NFS protocol nm - memory modify (constant address) ping - send ICMP ECHO_REQUEST to network host printenv- print environment variables protect - enable or disable FLASH write protection rarpboot- boot image via network using RARP/TFTP protocol reset - Perform RESET of the CPU run - run commands in an environment variable saveenv - save environment variables to persistent storage setenv - set environment variables sf - SPI flash sub-system sleep - delay execution for some time source - run script from memory sspi - SPI utility commands tftpboot- boot image via network using TFTP protocol version - print monitor version |
