Huawei H883g Mistake

Hi, I own a Refurbished Huawei H883g. I know that this phone came stock with the Portico 8.0.10211.204 which does not allow you to upgrade to the Windows Phone 8.1 OS. In order to get to that OS I flashed the GDR1 update to the phone, then updated to GDR3. As it is my phone has the following settings:
Name: Windows Phone
Model: HUAWEI W1-U00
Software: Windows Phone 8.0
OS Version: 8.0.10521.155
Firmware Revision Number:
1030.5614.01000.20900
Hardware Revision Number: HD1U8835M Ver. B
Chip SOC Version: 8230
Now that I flashed the phone though, I did more research after some trouble and found out that due to drivers I can't upgrade to Windows Phone 8.1 after all. Not only that, but now that I have flashed the phone I can't get 4G service and am stuck with EDGE. Now I just want to flash the stock ROM back on. My problems:
1. I'm a total amateur and barely got through the first flash.
2. I can't find the stock ROM.
3. I'm assuming I'm gonna need the original drivers as well.
4. I need the bootloader as well.
-OR-
If any one could tell me how to get 4G service back I can just stick with the OS I have and be happy.
Pleeeeeeeaaase help me!

C5J6- Do I Have To Flash The BIOS While Upgrading OS?

Do I have to flash the BIOS while upgrading OS's if my C5J6 has newer one than 2.02?
Hello to all, I'm going to receive my C5J6 Dual boot and first I want to do is to update stock Andriod to 5.0 and Windows to 10. All tutorials contain operation of flashing the BIOS to version 2.02. Can I upgrade both OS' without flashing the BIOS if I get my C5J6 with a newer BIOS' version? If not, how can I backup the newer BIOS to flash it back while updating the OS'?

Help in downgrade Razer Phone 2

Hi there, I want to downgrade to Oreo but I can't found the firmware for MR1, but I have a doubt, is "MR1" a model of my phone? or a firmware version?

MR1 refers to the security patch. Also, MR1 is Pie. the only Oreo image I know of is the AT&T specific one, and its garbage, but good luck. Download the factory image from Razer and use the flashall command in fastboot. Use a windows 7 machine for less problems.
Why would you want to downgrade, jw?

All the firmware files for our device can be found here: https://developer.razer.com/razer-phone-dev-tools/factory-images/ there are 8.1 images for the global varient here.
