Tried manually flashing firmware with fastboot and now no system

[AMShiech]

Ok so I've been having a hell of a time with this phone so far. I have the boost mobile variant (xt1766). I unlocked the bootloader, installed twrp, but forgot to make a backup before flashing supersu, after which my phone would no longer boot so I flashed lineageOS. It booted up fine but I had no 3g connection so I wanted to go back to stock. I downloaded the stock firmware, but couldn't get RSD lite to install on my computer so I extracted all the files and flashed them manually with fastboot. After that my phone wouldnt boot and TWRP couldnt mount the data partition so I couldnt restore my lineage backups. I had to format the data partition in order to restore from backup but now I have nothing on internal storage, and my phone wont boot into system unless I boot into factory mode from the bootloader. It boots up fine in factory mode but now I have no network connection, no service whatsoever.

Under sim status it says Network: unknown, cellular network type: unknown, Service state: Radio Off, etc. I tried manually turning the radio on but that didn't work. I really just want to go back to stock but I don't understand how to accomplish this. I flashed everything in the firmware package in the correct order, and somehow it just rendered my phone useless. any help would be much appreciated. I've tried just about everything and I'm at a loss here.

Update:

I successfully got back to stock. For some reason executing the fastboot commands manually one at a time didn't work so I made a bat file with all the proper commands, executed it, and this time it worked. Not sure why it didn't work the other way but it might be because I didn't flash the stock recovery so as not to replace TWRP. Apparently when flashing firmware its all or nothing.

Are there any custom ROMs with 3G functionality for this device? Cuz so far every single one I've tried gets no network connection but this stock ROM is lame.

Not "lame" unless that's the latest descriptor for a reliable, fully functional, device optimized ROM that just works. If you want additional bling/tweaks flash Xposed framework and a few well regarded modules like GravityBox.

Alternatively, you can cycle through the various custom ROMs and decide which suite of compromises you're willing to live with. Suggest a careful read of the relevant ROM thread before diving in. Be sure to backup what works (including stock!) and store those nandroids on a SD card and/or off-device.

Good luck.

That's because you're on boost, not many ROMs here have CDMA support. There is a fix in the help section. But stock is fine for me. Gravitybox and all features of any of the broken unofficial ROMs are all there. Rock solid, and LTE. But flash away dude.

I haven't been able to install the Xposed framework. Xposed installer says my CPU architecture is incompatible. When I flashed Xposed v89 for nougat my phone wouldn't boot past the boost logo. I keep hearing about people getting Xposed working on this device but I can't figure out how they're doing it. I would love to be able to have gravity box on this ROM.

Apparently the purityOS guys made an unofficial work around a while back but all the download links in that thread are dead and I can't find it anywhere else. It's my understanding that i need to be able to set selinux to permissive on boot in order to install Xposed.

No, regular Xposed. Wipe cache and dalvik, and wait. Let it sit 5 - 10 minutes. It has to optimize everything. Make sure it's the arm build. It works fine, just gotta let it sit. First boot takes a good bit.
Or use magisk, and install Xposed through that.

Do not use that old purity crap. That's why the links are dead. It's old crap. Xposed works fine with no extra steps or messing with selinux.

That's BS; don't overcomplicate things. Xposed framework installs fine in enforcing mode. Make sure you have the correct framework for Android 7.1 (SDK 25) and your hardware (arm). You will also need the corresponding management app. There is no need to wipe anything before/after flashing the framework although doing so can't hurt. First boot will take awhile; patience is a virtue.

Got Xposed working now with gravitybox and edge in full effect so this stock ROM is now much more tolerable. I guess I had the wrong version of Xposed installer and didn't wait long enough for boot to finish.

It broke safetynet though which I fully expected. I'd rather use the systemless Xposed magisk module so I can pass safetynet but I can't get any magisk modules to install successfully either through magisk or by flashing with TWRP. Apparently I'm not the only one having this issue either and it doesn't look like anyone has found a fix for it as of yet. I guess for now I'll have to live without Pokemon go lol

Well yes there is most definitely a fix. Your problem is the f2fs loopback bug. Your solution is the f2fs loopback bug workaround module. It's in the magisk manager app. Download there, but install it in twrp. Then magisk modules will work. You must have halted your research a little early because this is well known, and posted in many places.
You still won't pass safetynet with systemless Xposed. Which a little reading would have also revealed. But, you can turn off Xposed in magisk , then reboot and pass safetynet. Do whatever it is you need safetynet for, then turn it back on and reboot. You must completely uninstall the Xposed you have to use magisk Xposed. You must use the Xposed installer APK that's linked in Xposed for magisk so it recognizes systemless Xposed. So uninstall Xposed with uninstaller zip, uninstall Xposed APK. Wipe caches. Then you can just go in magisk manager, scroll to the bottom of downloads, install Xposed sdk 25 module. Also Xposed installer APK linked 8n the readme that pops up when you click the Xposed module in magisk downloads. See screenshots below.

Also, there is more to pogo than safetynet. There is an entire thread devoted to it (more than one) in the magisk section of the forum.
You have a bit of reading to do in order to do the things you want. It's all very easy to find. You don't seem to be looking very hard.

Also I certainly hope that's not the app I think it is (the smiley face)? You're not allowed to promote or speak of that "warez" here. So screenshot is not a great idea.

I'm well aware that the problem is f2fs loopback but due to the bug I'm unable to install the fix. Can't install magisk modules so a fix in the form of a magisk module doesn't really help me. Ive tried installing it with TWRP a couple times with no success. As far as PoGo I've actually never even played that game. Was just curious about it.

And I'm not sure what app you're referring to but that "wow" face is a chrome shortcut. Changed it cuz I didn't like the default grey square.

Trend continues; reread post you're disparaging. Or module OP. f2fs loopback 'fix' gets flashed in twrp or via fastboot (for the adventurous).

 

[AMShiech]

I edited my post shortly after your quote. Tried installing with TWRP more than once. Doesn't show up in magisk modules.

 

[AMShiech]

Just flashed with fastboot and now it seems to have worked. Fastboot for the win.

Maybe all caps will help out
go inside magisk manager> downloads search F2FS LOOPBACK BUG WORKAROUND, FLASH INSIDE TWRP!!! WILL NOT WORK IF ATTEMPTED TO FLASH THROUGH MAGISK MANAGER!!!!
