I have a late 2011 MacBook Pro 17". I replaced the SSD after it failed and I am just trying to install the OS. I am using Shift-Opt-Cmd-R with the laptop directly hooked up to the router. I get the apply logo for a few seconds and then the screen resets to a blank white screen for hours and I cannot get further. What, if anything, can I try?
Oh....gosh....try doing a reset smc/pmu and zap pram. I presume that after you installed the SSD you enabled TRIM, which is not enabled on all non-Apple SSD's by default. How to do that first part can be found here: yup, it's a link

and 2nd part:

do you really need to hold down the Shift key as well ??? I though that just Option, Command-R alone would work... You should see a spinning globe and progress bar.....
You might also need a firmware update for that model of MacBook Pro, though how you're gonna get it to install is beyond me or even to check the firmware version....anyways, go here for that info:

As you are booting (or trying to boot) into the installer, OS X Tools Should still be available to you. As it's trying to boot, move the mouse to the top center of the screen and click. OS X Tools should show up, and from there, you could run Disk Utility and Disk First aid.
other than that, starting up in single user (safe) mode might be helpful to troubleshoot. Reboot, holding down the Shift key only.
otherwise, if you reboot and hold down the D key, you get Apple Diagnostics which runs a basic series of tests on your MacBook Pro

Try booting with Command + R for the OS which was installed on the old drive or Command + Option + R for the most recent version of macOS available for this system (High Sierra).
If you have access to another Mac, then you can try creating a bootable macOS USB installer.
To make sure you don't have some other hardware issue, try booting from an external boot drive. You can create a bootable Knoppix Linux USB drive using Etcher (Mac/Windows/Linux). Use Knoppix version 8.2 instead of version 8.6 since the later one has been a bit glitchy with the graphics. Option Boot the USB drive and select the orange icon labeled "EFI". It may appear the laptop is frozen at the Apple boot picker menu, but Knoppix is most likely booting (it is a Mac issue). If this boots to the desktop without issue, then the laptop hardware is likely Ok. If Knoppix only boots to a command line with an error mentioning unable to start X or something like that, then your GPU may have issues.
This model is known to have faulty GPUs. Sometimes you can force the laptop to use the Intel GPU instead, but this is tricky to do if you cannot boot the laptop.
Edit: Try removing the new SSD and see if you can boot successfully to Internet Recovery Mode. Maybe there is some issue here.
I need to reinstall the OS but get a blank white screen. What do I do?
