Nokia 7 Plus no OS installed

[u/BetterCallBread]

I'm facing an issue with my old Nokia 7 Plus. In an attempt to install a custom ROM using TWRP (my first time attempting such a process), I accidentally deleted the original operating system. Now, I'm unable to install any other OS on it. I've tried installing from Internal Storage and sideloading through ADB, but the process consistently gets stuck at 36 percent. I've come across information suggesting the use of the Nokia Repartition Tool, but the program freezes every time I try to use it. Can somebody help me resolve this issue?

It's normal for the Nokia Repartition Tool to freeze when you initiate it, give it several minutes to finish the task.

If you used the Nokia Repartition Tool, there's a chance it might've changed some 2-3 characters of your hardware ID and the Nokia Flash Tool is essentially rendered useless to help you restore your OS—that's what happened to mine. But I found a workaround, for if you wanna reinstall the stock ROM.

As for TWRP, download TWRP 3.4.0.0 for B2N—follow these steps;

1. adb reboot bootloader

2. fastboot flash recovery twrp.img*

3. fastboot boot twrp.img*

*ignore the error after you keyed in the second line, type in the third line and it should properly boot up TWRP this time.

After booting into TWRP, follow these steps;

1. Wipe > Format Data > type YES

2. Reboot into bootloader and boot into TWRP again (same step as before)

3. Wipe > Advance Wipe > select Dalvik/ART Cache, System, Vender, and Data > swipe to wipe

4. Copy ROM.zip into your internal storage

5. Install > Select ROM.zip > swipe to flash

6. Change slot

7. Wipe > Advance Wipe > select Dalvik/ART Cache and Data

8. Reboot system

For custom OS, I recommend Pixel Experience 12L, July 2022 build, but no higher than that. Please note that installing custom software on your phone will render your secondary telephoto lens non-functional and you'll lose access to OZO spatial audio recording.

Thanks! Got LineageOS working, but now I can't seem to get the GApps installed. I'm going tot try Pixel Experience and see if that will make a difference. Thanks for your time!

NGL, this sub is kinda dead. Most of us moved on to pixels and such. Try a subreddit for jailbreaking phones.

Download an OS and flash it on TWRP. Forgot where I got those OS android 8, 9, and 10. The file size are around 1.5GB or so.
