[General Questions and Answers] scoperooy:
Hello everyone,

I am looking to buy new Android phone but with best camera and other qualities. Can anyone advice me which phone should i buy. Budget is not a problem.

Thanks
[General Questions and Answers] Raiz:
If you're looking overall for the best camera, Google Pixels are a solid choice. Also Samsung phone can be a great choice for cameras. If you don't play heaving games and have normal sized hands, take the Pixel. If you want a big, beautiful, high resolution screen, samsung is the choice. (and heavy gaming is better handled as well). So it's between the google pixel 5 and samsung S21.

But tell me more criterias if you have, it can always help. Like headphone jack, or wireless charging, 120Hz screen...

If you don't mind take apart your phone, you can use EDL method - but you know doing so will definitely void the warranty, and the stubborn triple-color company could remove these pads in later batches.

Firehose programmer for this phone is attached here.

Since we didn't grab downgrade OTA package for Russian variant, they cannot pass full OTA package verification and has to use EDL method for downgrading ABL. Thanks to Russian users for providing info.

In case Android 12 update from future cannot be downgraded, you'll have to use EDL method as well.

Example of using edl.py from bkerler (https://github.com/bkerler/edl):

edl.py w abl_a abl_proto_e253b67f.elf --memory=ufs --loader=prog_firehose_ddr.elf
edl.py w abl_b abl_proto_e253b67f.elf --memory=ufs --loader=prog_firehose_ddr.elf
edl.py reset

Keep in mind doing so will 100% void your warranty, and you cannot relock the bootloader.

You can use them for OS rooting.

Also after @jnappert 's testing, the workaround works great.

1. Sideload 00WW_1_150-B01 OTA package under recovery. You may see downgrade not allowed prompt but it will install anyway.

2. Reboot to bootloader under recovery mode. Although Anti-Rollback protection is triggered, the abl is not protected and is now downgraded to vulnerable build.

3. You can now follow the guide to unlock the bootloader.

I hope this will help everybody to bring up custom rom development for this phone.
[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] Volski_:
Does that mean that they forgot to blow eFUSE of secure boot in this model? On a different device, once I flashed tampered ABL image after unlocking (and unlock_critical) the blootloader, XBL refuses to load ABL because of tampering. It hard bricked the device, but EDL mode was working.

It could be that ABL_proto image that you extracted might be signed by the OEM.

- installed adb and drivers

- enabled USB Debug

- bootet to stock recovery: "adb reboot recovery"

- in recovery "apply update from adb"

- adb sideload 00WW_1_150-B01 from post #3

- rebootet to fastboot and continued with steps from post #1 to unlock bootloader

- after reboot device updated directly to 00WW-2_200

I was lucky enough to get this phone from bh photos as shelf stock and it shipped with android 10. They are currently on sale there for $320. I installed and unlocked bootloader. I may get a pixel as a backup so id be willing to test recovery,roms etc...when someone comes up with something. Ive been out of the Android scene for a while and im curious if root is possible at this time or if that would require 3rd party recovery and/or a kernel

A little update

Bootloader unlocked

This time is a bit tricky

I tried to enter recovery and got "no command". Press volume up + power together every 2 seconds and I got actual recovery

Tried update from SD...no go

Tried update from adb... downgrade is not allowed

Somehow I went to fastbootd and nothing worked

I chose bootloader and this time elf file from post 1 worked (it didn't work when I enter bootloader normal way)

Now I have to find out where I can get boot to patch

Thanks, i read this while firstbooting my Phone, interrupted the Updates and unlocked the Bootloader as described in intial post. Thank you this worked like a charm.

I was overconfident then and tried to patch the bootloader of 00WW_2_200 with magisk v23. It made GSM and Sound dead and flodding syslog with restarting sound daemons. Magisk was installed and root working in apps and adb.

I was able to flash (fastboot/sideload) older Images, but Audio and GSM where crashing like before.

Finally Sideloading 2_210_OTA made the Phone usable again.

Please help.

Thanks!

Also - phone is currently on 00WW_1_140, is that the correct prototype bootloader I should be looking for?

And, as far as I understand, I can just take the OTA update as normal after unlocking bootloader, is that correct?

Now, a question - how does one find the OTA zip to extract boot.img from? After unlocking, my phone upgraded itself to 00WW_2_270, and it looks like I made the same mistake anfierli did before me. However, his solution no longer works - I cannot sideload-flash the 2_200 or 2_210 OTA.

At this point, I have fastboot and recovery available, but cannot load into Android. Can I try flashing the separate parts from the full 2_210 OTA via fastboot or will I screw my phone up further?

To Russian users:

Due to different project code was used, the downgrade package is not compatible with Russian version Nokia 8.3 5G. Therefore you'll have to take apart the phone and use EDL to write prototype ABL.

In case Android 12 update from future cannot be downgraded, you'll have to use EDL method as well.

Example of using edl.py from bkerler (https://github.com/bkerler/edl):

edl.py w abl_a abl_proto_e253b67f.elf --memory=ufs --loader=prog_firehose_ddr.elf
edl.py w abl_b abl_proto_e253b67f.elf --memory=ufs --loader=prog_firehose_ddr.elf
