[General Topics] TechySkills:
I had an Infinix Note 7, Which I format all + downloaded from SP Flash Tool, everything was gone, after 6 Months of Trial and Error, here is How I fixed it.

BASEBAND FIX:

Prerequisites:

Be on Stock Rom, (The one where Baseband was, AKA, the one you were using before you messed up.), Locked Bootloader, Download TFT Tools, (It is a Crack, so No links. Search on YT).

Open TFT Tools, and Go to Mediatek Section.

Go to Bottom Left, and Click Extras.

Click "Fix IMEI Baseband" and insert Infinix Note 7 by pressing Vol+Up Button.

It will take about 2-3 Minutes to fix.

Restart Device.

IMEI FIX:

Prerequisites:

Close All Apps, Otherwise the Process may Crash, Locked Bootloader, Download AfterSalesTool v1.5.1, and Modem Meta v10.2044.0.02, and a Valid Baseband (Use Above Method to Fix Baseband.)

To Fix IMEI, open AfterSalesTool, and Select Infinix from the Phone Category, and Select Model as X606, I repeat, X606.

Click the Connect Button and Insert Mobile without Pressing any Buttons.

After 2-3 Minutes, The Progress Bar will become Green, and then the Details of Phone will be listed.

Open Modem Meta Tool. Click: "More" with the Option: "DUT in Meta Mode"

Change the Port to USB, and from Auto Connection to your Device. (Connect Mobile if not Visible).

Click Connect.

It will give an error, Click OK, plug out the Cable from PC, I repeat, from PC, not Mobile, then Reconnect it, and again click Connect.

Now it will completely Connect. Search IMEI Download, And Input ONLY ORIGINAL IMEI, (Check from the BOX BEHIND). (Otherwise, I am not responsible for Thermonuclear War, or Jail, as It is Illegal)

Click Write, 2-3 Times, to make sure, it is written.

Restart Device and dial *#06#, Congrats your IMEI is Back.

WIFI MAC & Bluetooth MAC:

Prerequisites:

Locked Bootloader.

Open AfterSalesTool, Select Infinix from Category, Model as: X606.

Click Connect, and wait 2-3 Minutes till it is Connected.

Go to MAC Area, And the Heads are the Prefixes of your MAC Address, The First Head is for Bluetooth (BT Means Bluetooth), and the Second Head for WiFi.

If you have noted your WiFi and BT Mac, Well and Good, Go Flash it.

But, if you haven't, like me, go search for "MAC Address Generator - Generate Random MAC Addresses" and open the website.

Enter the Bluetooth Prefix and then select the format without any colons, or dashes.

Generate it, copy it, paste it in the AfterSalesTool.

If it says, it has an Illegal Character, again generate it, Try again. Keep trying till it successfully flashes.

Do the Same for WiFi Mac, copy its Head, Format without any colons or dashes, and generate.

Keep Trying till it Flashes.

Restart to check your MAC, it will also fix your NVRAM err = 0x10

And Viola, now you have WiFi MAC, and BT MAC, IMEI, and your Baseband Back!

Now Take a Backup through SP Flash Tool, as you Can't Take Any Risk.

Take Backup of NVRAM and NVDATA:

Prerequisites: SP Flash Tool, MTK Auth Bypass Tool, and a Phone with All those things Discussed Above.

Open Scatter File, Press Ctrl+F and search for NVRAM, note down physical_addr, and partition size.

Open SP Flash Tool, and Load MT6768 Scatter File.

Go to Readback Section, and click on add.

It will ask you to where to save it and *WHAT TO NAME IT*, Name it "Nvram.bin" (Name it exactly this or it will not detect in Restore) and click save.

Now it will ask the physical_addr and Partition size. Copy those values and enter there.

Click Ok.

Now click on Add again, it will ask for where to save it, Name it: "Nvdata.bin" (Name it exactly this or it will not detect in Restore) and click Save.

Now it will ask the physical_addr and Partition size, Go to Scatter file, Press Ctrl+F and search for Nvdata.

Enter those Values in the Respected Boxes in the SP Flash tool and click OK.

Disable Auth using MTK Auth Bypass Tool, or if you have Modified SP Flash tool, Disable Auth from there. and click "ReadBack".

Connect Mobile using Vol+Up.

It will back up in the Designated Place.

Restore NVRAM and NVDATA:

Prerequisites: Nvram.bin and Nvdata.bin of a Working Phone, SP Flash tool, and an unlocked Bootloader to avoid Errors.

Let's say you #### up again, and now, your IMEI and everything is gone, you want to flash the Backup now.

To flash it, Open SP Flash tool, and use this Modified Scatter File, to flash Nvram and Nvdata.

If you face any Checksum Error, Download Checksum Generator v5.1932.00, (Search it on Internet LOL) and Extract the ZIP and place it in your firmware, Cut the Original Scatter File, and place it somewhere, and place only the Modified Scatter there, and run the checksum generator as administrator.

Select Nvram and Nvdata Partition, Disable Auth, and use Download Only Mode, and Click Flash.

After 1-2 minutes, it will be complete.

After completion, restart your device, and Viola, Your IMEI and MAC's, and Baseband is back.
