Troubleshooting Kindle PW1 Bricked, screen works fine, no touch

Sun, 20 Aug 2017 09:28:02 GMT

I jailbroke my Kindle Paperwhite (5th gen) a few weeks ago, it worked just fine. Two weeks ago, my kindle's touch just froze while reading, then I just left it and the touch came back in the morning, the second time this happened, I kept it like that for a few days, then attached the power cable and restarted it, the touch came back, now this is the third time, what should I do? The screen works fine, and I was able to recover the documents folder, then I did a manual factory reset. Still doesn't work. :help::(



Aura Edition 2 SD Card Glued In?

Sun, 20 Aug 2017 07:23:33 GMT

Hello everyone. I'm looking for someone who has opened their Aura Edition 2. I just popped the back off of mine and it looks like the micro SD card is glued in the socket. I tried to gently pry it out with a fingernail but it doesn't come out easily. Has anyone been able to take theirs out? I didn't want to try to force it if it isn't removable. Thanks!



Aura My Kobo Aura One screen is broken

Sun, 20 Aug 2017 03:56:41 GMT

I purchased my Kobo Aura One a few months ago from eBay (product page (http://www.ebay.com.sg/itm/122232523817?ul_noapp=true)). One morning I bring it with me to work as usual and when I take it out of my back pack, the screen seems to be broken. Here is how it looks (http://imgur.com/Kx2dP6c): Image: http://i.imgur.com/Kx2dP6cm.jpg I never drop it and always keep it in my backpack when I travel and on my bed when I'm at home. So I have no idea what possibly happened. Is there any way to get this fixed? I'm living in Singapore. I really love this device but buying a new one would be a too expensive option :(



New iPad Mini?

Have there been any rumours about a replacement for the iPad Mini? With both of the two larger iPad models having been replaced recently, I was thinking that perhaps the Mini might be next?

Troubleshooting How to fix Kindle Paperwhite Error code 0

Sat, 19 Aug 2017 01:27:47 GMT

Two days ago, my kindle suddenly froze and displayed the "Your Kindle Needs Repair" message. I've searched online for solutions and came across this https://www.reddit.com/r/kindle/comments/2xojx2/how_to_fix_your_paperwhite_if_it_says_your_kindle/ But the problem is, kindle only displays for a fraction of a second (basically non existent) on my computer, but it does show up as Amazon Kindle under 'Devices and Printers' in control panel. However, I can's open the files in it. I contacted Amazon Support, but they simply said there's nothing they could do bout it, and advised me to get a new one.... Anyone with a fix, either to get kindle to display properly, or alternative methods I can try to fix this issue? Thanks for reading and I hope to find a solution.



Fire 7 and SD card

Fri, 18 Aug 2017 23:51:16 GMT

I have a Fire 7 tablet, which I use with an SD card. Every so often, the tablet tells me that the SD card has been removed--it hasn't--and I have to either restart the tablet or remove and reinsert the card. Then the tablet recognizes the card and everything goes along fine until the next time. Has anyone else had this issue? Is it perhaps an indication of the tablet beginning to fail?



Troubleshooting Send to Kindle vs KF8

Fri, 18 Aug 2017 23:05:00 GMT

Hello I have an issue with sending my hybrid mobi files created in Calibre via Send to Kindle. In theory my PW3 supposed to download file from the cloud with kf8 formatting. Instead I have azw file with old formatting and some weird line breaks. Everything is fine when I open it on Calibre or send via cable in mobi or azw3 format. Any ideas?



Tools Kindle backup

Fri, 18 Aug 2017 22:08:54 GMT

As attached, for the touch screen Kindles only. The main significance of this is, Amazon/Lab126 does not ship image files that include the 'diag' system. This is the only way to get the match pair of files: diag kernel and diag filesystem. It is a script, with a pair of tables to control what gets backed up. The tables could be changed for the earlier than KT devices if somebody was interested in doing it. You will need command line access to the Kindle to run this script. Translation: one of kTerm, telnet, ssh, serial port Installation? Un-compress it and put it wherever you want it on the Kindle (it will run from the user storage partition). Running it: It writes to user storage (/mnt/us/backups) so it will not work if you have user storage exported over the USB cable. Just call it by name, it will create the (Kindle:)/backups directory if required. In the couple of cases where the exact size to copy is not known in advance, it copies an over-sized chunk. That only happens when copying the two kernels and those can be trimmed down to size after they are copied. (The 'file' command or the 'mkimage -l' command will tell you how long the actual contents is.) *Edit:* The command to output the actual size of the kernel. Code: --------- ~ > od -A none -j12 -N4 --endian=big -tu4 mainkern.bin 2912364 ## as a way to check: ~ > file mainkern.bin mainkern.bin: u-boot legacy uImage, Linux-3.0.35-lab126, Linux/ARM, OS Kernel Image (Not compressed), 2912364 bytes, Mon Jan 16 12:39:07 2017, Load Address: 0x80008000, Entry Point: 0x80008000, Header CRC: 0x80F4D0EF, Data CRC: 0xDF2E6349 --------- The (legacy) header looks like this: Code: --------- /* * Legacy format image header, * all data in network byte order (aka natural aka bigendian). */ typedef struct image_header { uint32_t ih_magic; /* Image Header Magic Number */ uint32_t ih_hcrc; /* Image Header CRC Checksum */ uint32_t ih_time; /* Image Creation Timestamp */ uint32_t ih_size; /* Image Data Size */ uint32_t ih_load; /* Data Load Address */ uint32_t ih_ep; /* Entry Point Address */ uint32_t ih_dcrc; /* Image Data CRC Checksum */ uint8_t ih_os; /* Operating System */ uint8_t ih_arch; /* CPU architecture */ uint8_t ih_type; /* Image Type */ uint8_t ih_comp; /* Compression Type */ uint8_t ih_name[IH_NMLEN]; /* Image Name */ } image_header_t; --------- So the actual size of **this** mainkern.bin image should be: 64 (header) + 2,912,364 (data) bytes long. Consider the rest of the file as junk. For the curious, the script: Code: --------- #!/bin/sh ## (c) M.S.Zick, 2017 ## License: MIT https://opensource.org/licenses/MIT userStore='/mnt/us' images='/backups' target="$userStore$images" mkdir -p $target 1>/dev/null 2>&1 if [ $? -ne 0 ] ; then printf '\n%s\n' 'Make target directory failed.' 1>&2 exit 1 fi ## Extract portions of the source ## blkSize skipCnt cpyCnt source destination while read bs skip count src dst msg; do printf '\n%s %s %s\n' $msg dd if=$src of=$target$dst bs=$bs skip=$skip count=$count 1>&2 done [...]

Native sc: A Kindle Spreadsheet!

Fri, 18 Aug 2017 18:01:48 GMT

*Name:* sc - spreadsheet calculator. Another vintage(2002) linux command line application from the debian jessie armel repository...KUAL-ified for the Kindles! *Version:* 7.16-4 *Authors:* James Gosling, Mark Weiser, Martin Schulze and others. *From the README:* "This is a much modified version of the public domain spread sheet sc, originally by James Gosling, and posted a number of years ago by Mark Weiser as vc." *Kindle background:* There used to be a paid active content spreadsheet application on the Amazon website. Some attempt was made by twobob to port gnumeric to the kindles. See threads: https://www.mobileread.com/forums/showthread.php?t=223949&highlight=spreadsheet and https://www.mobileread.com/forums/showthread.php?t=208476&highlight=spreadsheet It actually seems to have run on twobob's kindles.. but he couldn't make a public release. The application here is not a graphic one like gnumeric, but is quite usable and has a lot of features. *Needs:* Jailbroken Kindle, KUAL, kterm. *Should work on:* All Kindles from KT1 onwards. Tested OK on: PW1. *Installation and usage:* * Extract the zip(sc.zip) into /mnt/us/extensions/. * After selecting the sc button in KUAL, a kterm window opens in landscape mode(for better usage convenience on kindles), with the required library pre-loaded. * For a tutorial type 'sc tutorial.sc'. * To start your own spreadseet, type 'sc mysheet.sc', or similar. * After the spreadsheet opens, enter ? for help. * Type q to quit. Type x to clear a cell. Type =1, =2, etc. to enter numbers. Use arrow keys to move around. * For more detailed instructions, see the files in the attached sc-docs zip file: sc-manual.txt and scqref.txt PW1 screenshots attached. *Links:* * 2010 article from Linux Journal: http://www.linuxjournal.com/article/10699 * 2014 article in xmodulo: http://xmodulo.com/make-spreadsheets-linux-terminal.html * 2002 mini-manual by John Floyd: http://www.adrianjwells.freeuk.com/minmansc.pdf * YouTube video: https://www.youtube.com/watch?v=xrX2isHDQu8 * One more YouTube video: https://www.youtube.com/watch?v=cItyzNmoxQE * Source mirror in github: https://github.com/dkastner/sc * Fork with bug fixes: https://github.com/n-t-roff/sc * Recent development, sc-im, sc-improvised: https://github.com/andmarti1424/sc-im



5th Generation Mirroring

Fri, 18 Aug 2017 16:09:48 GMT

Hello Folks, I'll try and make this short. I am trying to load movies onto a Fire tablet that has mirroring and take it to a remote area that has no internet and watch movies on a TV. I called amazon and they said it can be done with a Samsung TV which I have at the cabin. Not sure if it has the capability though. I can't check until I am there again. I was wondering if anyone knows if there is another way to connect without having Internet/wifi? I bought a new fire stick however the tablet can not see it when I try to mirror, however it does see the Roku box and works through that... another call to amazon! Thanks! L
