PCI DVB tuner fix for timeout waiting for DSP ready

I had a similar problem as described below on Ubuntu 12.04 and found that inserting saa7134-dvb into /etc/modules.conf did the trick for me too.
It's interesting though that it has been working fine before. I did recall seeing this issue once or twice, but this time it did not seem to have been resolved by multiple cold booting by itself.

    N.B. I've encountered the very same issue again today, and I forgot the mechanism again, wasting some more time again.


    To make it clear for future reference, if your computer boots up too fast, and any driver or application tries to access the tuner before the first automatic firmware update succeeds, the card freezes and becomes unusable until the next power cycling.


    So you not only need to blocklist the given driver from automatic loading on boot, you must not use the tuner in any way before you find a line in dmesg that reads "tda1004x: found firmware revision 29 -- ok". Remember that it could take up to 15 seconds (or perhaps up to 1 minute from power up?). The card can be used as usual after the first successful upload. Here's a good dmesg extract:

Tftp secret of TL-WR740N uncovered

I've found out that even this particular entry level router supports anti-bricking, so there's no need for soldering, unless of course you are modding. The method I used is the following: Set up a tftp server  on your PC and verify if it works correctly (configuration, permissions, firewalls, etc.) Rename your target firmware to wr740v4_tp_recovery.bin and copy it to your base folder (by default /tftpboot). I tested with openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin r43602. Set up the following static IP for your PC: 192.168.0.66 /255.255.255.0. If you're not sure about the firmware name on a different model, start a packet sniffer on your PC ( tcpdump -i eth0 -n -l ) and look for the name in the RRQ message. Preferably disconnect WAN from the router Connect the PC to a LAN port Power off the router Press and hold the reset button Power on the router After the leftmost (power) LED and the rightmost (padlock) LED turn on alone in a few seconds, release

Hidden TFTP of TP-Link routers

I did some more investigation after the positive results with the TL-WR740Nv4  (click the link to get introduced to the way of recovery). Most users report that devices and firmware updates released after a point in time usually have this mode enabled. If a firmware update is available from the vendor for your device, it's a good idea to apply that update before installing OpenWRT or dd-wrt UNLESS you own something for which upgrading will ensure incompatible with OpenWrt, like a TL-WR730N , and possible some other models (please report). Note that some old models have newer updates in different languages, those may also be worth a try ( TODO : compatibility?). Also remember that later on, tftp recovery will need a type of firmware image without a boot loader, so strip it with dd if yours has it ( grep U-Boot , or check the filename). Positive reported claims so far (personal results highlighted): TL-WDR4300 router 192.168.0.86 server 192.168.0.66 query wdr4300v1_tp_recovery.b
