-When browsing firmware folders on the website, a subfolder named "K26" mean the build includes Linux kernel 2.6.x . Such folders generally contain generic builds for MIPSR1/MIPSR2 routers. Generally, only old (pre-2010) models use the MIPSR1 architecture. Most routers made after 2010 use MIPSR2 or ARM architectures.+When browsing firmware folders, a subfolder named "K26" means the build includes Linux kernel 2.6.x .

-The other subfolders, such as K26RT-AC and K26RT-N contain dedicated builds, meant for specific router models. Unless you're experienced, it's recommended you install specific hardware builds. If there is no specific builds for your model, choose a generic build in the K26 folder.

-If you have a Netgear R-series router with Netgear firmware installed, you must first flash with one of the "Netgear R-series initial" files. Once you have an R-series initial build installed, you can then upgrade FreshTomato to newer versions using regular build files.

-MD5SUM files are available in each website folder containing firmware. You are strongly advised to run a hash program against the .zip file of the build you downloaded. Then, compare the value in that program with the listed hash value for that build in the MD5SUM file. If the two don't match, your download is corrupt. **Don't flash with that file** or you could damage your router. Try downloading it again and performing the hash check until the hashes match.+MD5SUM files are available in each website folder with firmware.

-Using backup .cfg files across different releases or router models is **NOT** recommended. At best, some functions may not work properly. At worst, restoring incompatible settings from a backup file can cause system instability, erratic behavior, or other problems.+Using FreshTomato backup .cfg files across different releases or router models is NOT recommended.

 If you have the Original Netgear firmware installed, **you must** use an initial build to install FreshTomato the first time. The initial zip files contain firmware with a ".chk" extension that a Netgear router can use to install FreshTomato. If you have the Original Netgear firmware installed, **you must** use an initial build to install FreshTomato the first time.

-After you've installed an initial build, you can upgrade to any appropriate FreshTomato version you wish. Regular build zip files contain firmware files with a .trx extension.
