I know there is another very similar thread that was just opened(http://ift.tt/1Oohym8), but his solution didn't help me so I'm making this thread.
I really need to save my internal data, so only as a last resort will I wipe userdata to save my phone.
First of all my phone is completely stock. Locked bootloader, unrooted, stock recovery, and stock rom. Last thursday(June 9th), I got the CM13.1 OTA update which I installed and everything went normal. It finished installing, restarted and booted up, optimized apps, rebooted, but then optimized apps again and again. I thought it might help to just reboot my phone, but it didn't. So I immediately started looking around for solutions.
I can boot into recovery and fastboot mode and since I can boot into recovery I started with wiping cache(Stock Recovery>>Factory reset>>Wipe cache partition). It took ~20mins which seemed like an unusually long time, then I rebooted and it still got stuck in the "optimizing apps/reboot loop". Next, I set up USB drivers, ADB, and fastboot since it seems to be very important to have those set up. I used a few guides to get them properly set up and I checked that they were correct by checking that the cmds "adb devices" and "fastboot devices" returned my device, which they did. I saw someone saying he saved his friends OPO by just ADB sideloading a CM zip file, so it looked hopeful in my case. I downloaded cm 13.0 and 13.1 zip files and tried sideloading them with the cmd "adb sideload cm13.zip". I tried both and they both got to around 50% complete and the install failed. Some of the red text said, "Package expects build fingerprint of oneplus/bacon/A0001:5.1:6.0.1..... & E:Failed to install /sideload/packages.zip ". Next I tried installing TWRP, which looks like it requires an unlocked bootloader to flash it(even to to just boot into it). From all my research it looks like there's no way to unlock the bootloader without wiping data. Even the OPO toolkit says you need to wipe data to unlock your bootloader.
One thing I haven't looked too much into is using fastboot to save my device. This guide http://ift.tt/1OohXEW shows to flash userdata userdata_64g.img, which I assume wipes userdata.
Maybe I'm just overlooking some simple fix, but if anyone can help me I would be eternally grateful.
