You **MUST** also flash corresponding images.
The Kernel image and the System image are **MATCHED SETS** That is a total of **TWO** matched sets, one for the Main system and one for the Diags system. Quote:
The image size of mmcblk0p1 is larger than what fastboot can handle. Quote:
At least not until after you get the PEBKAC out of what you are already trying to do. |

Recap of steps
To Recap.
Got a PW1+3G, stuck on Boy reading under tree Got a serial connection running Errors in loading the Kernel Image ## Booting kernel from Legacy Image at 70800000 ... Image Name: Linux-2.6.31-rt11-lab126 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 4608576 Bytes = 4.4 MB Load Address: 70008000 Entry Point: 70008000 Verifying Checksum ... < Forgot what the actual error message was Loading Kernel Image ... Got the kernel, diags_kernel, system and diags files from: http://ixtab.tk/kindle-touch-images/...pw520_wlan+3g/ extracted all of them. Got fastboot for kindle and compiled it Started the KPW, interrupted the boot from the serial terminal uboot> bist bist> fastboot on pc side ran: ./fastboot flash kernel main_kernel.img ./fasbtoot flash diags_kernel diags_kernel.img downloading 'diags'... OKAY [ 2.371s] writing 'diags'... OKAY [ 2.028s] finished. total time: 4.401s Diags partition is flashed way too fast (65MB). ./fastboot flash diags mmcblk0p2.img rebooted, restarted on Diag mode, no longer getting checksum errors, went straight to diags menu Entered U to get to USB device mode. The Kindle drive appears, both under windows and linux copy over the mmcblk0p1 file to the root of the drive. unmounted properly then enter the login prompt. Entered root credentials Browse over to /mnt/base-us [root@kindle us]# dd if=./pw_3g_5.2.0-mmcblk0p1.img of=/dev/mmcblk0p1 716800+0 records in 716800+0 records out 367001600 bytes (350.0MB) copied, 139.472548 seconds, 2.5MB/s K [root@kindle /mnt]# mount /dev/mmcblk0p1 ./mmc/ JBD: no valid journal superblock found EXT3-fs: error loading journal. mount: wrong fs type, bad option, bad superblock on /dev/mmcblk0p1, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so rebooted. try to disable diagmode and get the following Could not mount/access customer partition! rebooted, checked again the contents of the kindle drive and the mmcblk0p1 files are no longer there, whatever file i copy is no longer available after reboot. So probably the flash memory is gone. Any other ideas that i can attempt. Thanks Last edited by amirseni; 02-15-2015 at 07:18 AM. |

One possible problem source, since the resulting binary is not known to work properly. As advised by others in this thread, use one of the known working binaries if possible. Quote:
If not an editing typo - this is probably significant. Quote:

Just rebooting the device will not help at this point. Quote:
Which according to this thread, was never touched. **BUT** The same /dev/mmcblk0p3 is used by both the main and the diags system **and** the diags system did not complain about it. So this is probably a case of an error of the complainer, not of the complainee. ![]() Post on e-bay as "for parts only". |

You should use a 1.8 volt (not 12 volt) serial port. OR Use a USB-to-Serial adapter with the serial side set for 1.8 volt operation. |

I used the cp210x usb to serial adapter. It worked reliably without using a 1.8V level shifter..
It's similar to this one on Ebay Just plugged the TX, RX & GND pins, left the 3V & 5V pins disconnected |
