Clean format, need to install software again!

I was trying to clean install Oxygen OS 4.0 onto my OnePlus 3. I did a huge mistake of formatting my entire data off of my OnePlus 3 using Wipe > Format Data > Yes in TWRP and now I cannot use my phone.
I don't know how to install the OS on the phone again and I am stuck. I don't even have a spare phone right now.
Can someone please help me? I tried checking the other forums, but they were confusing and I didn't understand anything. Please help me.
I tried downloading the software from OnePlus's website, but I couldn't install it through ADB cause the file is for some odd reason corrupt.
Please, somebody help me. I can't even send it back to OnePlus cause I am in a different country ATM.

I had trouble with OB10 and adb. Said it couldn't read the file. I instead flashed TWRP and enabled mtp from there. I then pushed the full ROM to internal storage. Fastboot flashed the stock recovery and used 'upgrade from internal'. That flashed it fine. Then I reinstalled TWRP and SuperSU.

Have you downloaded the full ROM? Make sure you download the full rom from oneplus's website or any of the mirrors available on various forums on xda. Flash it normally like you flash a custom rom. It will work as I have done it a lot of times. Your file must have been corrupt.

Go to: h*t*t*p*://downloads.oneplus.net/oneplus-3/oneplus_3_oxygenos_3.2.8/ (REMOVE STARS) download both stock recovery and rom of OOS v3.2.8 (located at the bottom of the page). Flash stock recovery via fastboot (I hope you know how to). After it was flashed, disconnect the cable, turn off the device in fastboot (power off). Then hold power and volume down keys down to boot into recovery. From there ADB sideload the stock OOS v3.2.8. Let it boot up and update to OOS 4.0 via OTA.
P.s. If you need the actual steps, let me know. I'll update it in this post.

I had an issue with custom twrp + Freedom OS v2.0 (OOS v4.0). No xposed, a lot of battery issues with performance and toggling settings issues too. So I decided to stick with Freedom OS 1.7 (OOS v3.2.8) until OnePlus fixes the issues, with xposed available for Nougat and official twrp being released to support Nougat. Also, whenever I flashed custom twrp, which was recommended by the dev, it always asked me for a password. I did have PIN code with fingerprint option, a pattern option or none at all. All of which did not help bypass it, even using "default_password". I was stuck with OOS v4.0, somehow, with no twrp to work with as it locked my data. I backed my files before flashing from OOS v3.2.8 to OOS v4.0, lucky me. I managed to do what I have explained in the first response.

Several issues while trying to root pixel c

Hello, I am in need of assistance on rooting/my pixel C device.
I was trying to follow the steps outlined in this webpage: https://forum.xda-developers.com/pixel-c/general/guide-unlock-bootloader-install-custom-t3307183/page27
The tablet by itself had 8.1 to start out.
The steps I did so far is
1. Successfully unlocked the bootloader (the 30 second boot time and the beeping noise)
2. Installed TWRP
3. Installed superSU via TWRP
4. flashed the AOSP kernel from this link https://forum.xda-developers.com/pixel-c/development/rom-t3569215
5. Upon system reboot, I noticed two issues:
Issue 1: The apps is pretty empty, including no google play store. I am guessing this was by design, to keep things simple. In addition, I think the original author was saying to install opengapps manually.
Issue 2: Every time I boot to system, I get the message "google connectivity service stopped" error in the beginning (that wording might not be precise). I was able to connect to wifi and bluetooth with no problem, but maybe the connectivity service is responsible for something else, and it is concerning.
6. Another thing I noticed is an issue is when I boot back into TWRP, my internal storage is 0mb. In research it sounds like I need to implement some sort of passcode, as it might be due to the internal storage being encrypted (although I didn't set up any manual encryption myself).
However, when I boot back into system and look, there is no way to set up a screen lock passcode. There is a method to encrpyt the tablet data, but I didn't pursue that, because it projected a long wait time. (If this will indeed fix the problem I will do so)
If I format data through the twrp system, the internal storage comes back.
7. Nonetheless, I was hoping I can still navigate through the system if I just install opengapps. Therefore, I went to opengapps.org, and chose the arm64, 7.1 stock file to download, as this was the default choice it offered (and I couldn't find 8.1- please let me know what the correct one to install is)
8. I then used adb sideload to install the gapps. (As I couldn't access the internal storage)
9. Now, when I try to reboot to system, the TWRP recovery keeps on coming up, every time. Essentially a TWRP bootloop.
My wish is to just get back to the stock 8.1 os with root. Even if I go through a format erase on twrp, the aosp design defaults. Maybe it isn't completely erased?
I have been working days and nights. Maybe it is because I am a novice and a total newb on the pixel C, but looking everywhere it shows similar yet different suggestions, and hasn't been giving me what I am looking for.
Any insight/advice you can give me will be greatly appreciated.
Thank you for reading my long post.

I think I found the correct gapps just by a Google search. It is unfortunate that they're not just out there in plain view on the OpenGapps site. So you flashed the 7.1 apps, and did you get an error message while trying to flash them via TWRP?
To be quite honest, I had a lot of difficulty rooting and flashing a ROM on the Pixel C, myself. The process took me a couple days. I really had to play around with the drivers and the SDK...the latest wouldn't install to my computer unless I installed it using Android Studio. Once I finally had everything set up right, which I can't even remember how I had it set up, it worked. One ROM I flashed didn't boot, and the Lineage one did. Now, I'm on Resurrection Remix, my favorite ROM ever! Hope this helps!

Hi, I have a suggestion for ya, You can either flash your tablet with the stock rom : https://developers.google.com/android/images , change the recovery to twrp and root your system with supersu Or you can install lineage 15.1 (oreo) + opengapps oreo 8.1 + supersu/magisk15 don't forget to change the vendor image and the boot image also if you want to have access on your internal storage on twrp. Hope that it will help you.

Thanks guys. Since this time, I was able to try different things and was able to get things rooted and erased using a combination of twrp and the original stock rom.
However, during this process, the TWRP recovery was overwritten with the stock one, and when I try to re-flash the twrp recovery using adb (at the Fastboot, using command: Fastboot flash recovery twrp.img ), command line just stalls with no progress.
Has anybody else encountered this before? Any way to re-flash the twrp file? thanks in advance.

[BOOTLOOPHELP] Stuck in bootloop without os

I was trying to install Lineage OS on my Nextbit Robin. I have never done this before, which is why I messed it up. I install TWRP and unlocked my bootloader, but I did not put the Lineage OS ROM.zip file into my internal memory. Sideloading isn't working, and since Nextbit has been bought by Razer, the official stock ROMs don't work, etc. I need help in installing an OS (stock is fine). If you could also guide me through installing Lineage OS, that would also be appreciated.
Thanks!
Let me know if you need more info.

Why do you use sideloading ?
Just boot into TWRP , go to mount and select enable MTP.
Then connect your phone to your PC and transfer the lineage os zip file ?.

Help: None of the ROMs I tried installing are booting. (SM-A720F)

Hello,
I'm really new to all this android thing, but I decided to root my Samsung Galaxy A7 2017 using magisk, for which I used this guide.
After some time of enjoying some root features I decided to try a custom ROM, the first one I tried was this one, since I heard that resurrection remix is one of the most feature rich ROMs. After flashing the zip file with TWRP I booted into system, I read that the first boot after flashing a ROM usually takes up to 10 minutes, but after just 1 to 2 minutes of showing the boot animation the device restarted and sent me back to TWRP. After this I did some searching here on XDA and watched some youtube videos that claimed to solve the problem, but none of them worked for me, as they mostly just said to reinstall the ROM and wipe dalvik cache and normal cache.
Since my phone came with stock android 8.0 I thought of installing LineageOS which was only official ROM based on android 8.0 that I could find for my device, but the same thing happened, boot animation for 1-2 minutes and then it sends me to TWRP.
In both of these attempts I downloaded everything to my pc and then moved it to my phone's internal storage.
I noticed that people were donwloading the files direcly from the phone itself, so I did that with LineageOS and after tring to boot it gave me the error "Encryption unsuccesful" with the option to reset my phone, I search in google about this problem but I'm doubtful of what to do now.
I would apreciate if someone told me what this error is, what could be the cause of it and how to fix it, and most important of all why won't my phone boot into a custom ROM and how can I get it to do so.
Thanks in advance!

Nexus 7 2013 won't get past Google logo after trying to update OS

I was trying to update the OS on my Nexus 7 2013. I was able to connect it to my PC and unlock it and erase user data using adb commands. But after that it will not go past the Google logo in Recovery or regular Start mode. When I run "adb devices" it does not show up, though my computer does see it since I can run the lock/unlock adb commands and they work. I have uninstalled/reinstalled different adb drivers for the devices. I've tried using 2 different PCs. I can not get adb to fully recognize the device. I tried the Skipsoft Android Toolkit, and it too reports "no device detected".
Have I completed bricked the device? Or is there some way out of this that I haven't though of/found on the internet yet?
I hope someone here can help me!
Thanks!

Assuming you're on stock, try flashing a factory image from Google themselves. This reflashes everything, like stock OS, recovery, bootloader, etc. I'd choose the latest version found here: https://developers.google.com/android/images#razor As long as you understand that this wipes data, then give this a shot and let us know the results!

I found the "Nexus Root Toolkit" windows app. It was able to communicate with the Nexus 7 and restore the factory ROM and I could get it to boot! Now, I've tried about a dozen times to install LIneage, but it keeps getting an error the point of trying to install the ROM, and I haven't figured out what the error means or how to correct it. I've tried multiple TWRP versions and Lineage OS versions. It's driving me nuts!

Are you trying to install the official version of 17.1? If so, you'll need to look at the install guide on the LineageOS website here: https://wiki.lineageos.org/devices/flox/install
As far as I can tell, you cannot use TWRP, or at least the official TWRP, with this image. You'll need to use the LOS 17.1 Recovery found on the downloads page. If you haven't already, you're going to need to repartition the device with the instructions found on the install guide that I linked.
If this isn't the ROM in question check out the thread for that ROM and see if anyone else has any issues with installation.

Thank you! I did manage to get 18.1 to flash and load, after using a repartiion tool I found. However, I can't get GAspps to load, saying there isn't enough room on the partition. Now, I'm trying to use NRT to get back to stock (like I was able to do earlier) but now it is getting stuck at the Android 6 startup animation (4 round icons). I'm wondering if it is because I ran the partition update and somehow have to put that back to get the stock ROM to work.

The only suggestion that I would have is to flash the smallest GApps package possible, and before flashing LOS 18.1, wiping pretty much everything, then flashing LOS and GApps. Since OpenGApps doesn't make an Android 11 package yet, I don't know much about the other package providers, but that's all that I can think of. Hope this helps!

I wound up flashing Stock Android 5.0 and it worked. Now I'm updating to 6 via the software upgrade in the OS itself. I feel like this thing is just too old and not large enough memory to handle a custom OS.
