Sir,

Is there any way to unlock dual sim because it's only support single sim! I believe It have the hardware but it's been locked by software!

and is there any way to flash nokia 8.3's firmware on 8 v?? please help if you have ideas
[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] hikari_calyx:
Absolutely no chance.

TA-1257 cannot accept the firehose programmer provided here (EDL script will freeze), which already proved it cannot accept TA-1243/1251 firmware.

Even if you manage to use some sort of UFS/ISP programmer, it still cannot be unbranded into regular 8.3.

Hi, I am new here. I have Nokia 8.3 5G and my device version is 00WW_2_27B_B01 with Android 11. I want to downgrade it to Android 10. I am not able to sideload it with Android 10, because Android 11 is already installed and I cannot sideload the mobile with a lower version. So it seems the only option is to unlock the bootloader and then flash it.

The first post by hikari_calyx on Feb 15, 2021 says "If your phone has Android 11 installed (00WW_2_180-B01 or newer), then this bootloader unlock method has been blocked, but there's known workaround for this. Check 2nd reply for details." Then in the 2nd post he mentions the "EDL method" without any details. Is "EDL method" the way to unlock bootloader with Android 11?

Where exactly to obtain the edl.py script and the other two .elf files? Where are the detailed step-by-step instructions to perform the "EDL method"? The author also posted an image showing the internal hardware of this mobile. What is the purpose of that attachment?

If anyone has successfully unlocked the bootloader of Android 11 on a Nokia 8.3 5G mobile, kindly share necessary details. Thanks.

Hi @hikari_calyx, thank you for helping. I followed #3 to sideload the mobile in Recovery mode. On the mobile it shows a warning "downgrade not allowed", but it finished with "Install from ADB completed with status 0.". However, on the computer, it shows "(~94%) adb: failed to read command: No error". Can you please confirm whether sideloading 00WW_1_150-B01 OTA has succeeded on my mobile or not? Can you please also explain what does "Although Anti-Rollback protection is triggered, the abl is not protected and is now downgraded to vulnerable build." mean?

Then I tried your instructions in the first post (#1). However, fastboot is not able to find any device. What is this issue about? How to resolve this issue?

Also, is there a post to wipe and install a fresh Android 10 after the unlock? Thank you.

Hello there, I'm not too well versed in the Java/Android world, but recently aquired this phone used.

Am I correct in thinking that, If I want to build a custom rom for this phone, the general steps are:

1. unlock bootloader (btw, thanks for that!)

2. build and flash TWRP for my device

3. build custom rom

4. install custom rom through TWRP

Another question is, can I use code that is build for a device with the same chipset as base, like the Google Pixel 5? Are there major drawbacks in doing so?

[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] catzilla:
Would like to confirm, upgraded from android 11 to 12 with a small hiccup:

Steps:

1) Download android 12 update, link on previous page

2) Use payload_dumper to extract boot img

3) Copy the extracted new boot img to phone and patch it using magisk. Copy the newly patched boot image to pc

4) In magisk, elect to uninstall magisk (restores original boot so update can be applied)

4) adb reboot recovery

5) choose adb sideload, and then from pc adb sideload <update>.zip

6) After it's done installing, choose reboot to fastboot

7) fastboot flash boot magisk_patched-23000_V6RRL.img

8) fastboot reboot

9) ***System booted but - in my case, I had no root at this point, I think boot got flashed to wrong slot

10) adb reboot fastboot

11) fastboot flash boot magisk_patched-23000_V6RRL.img (this time it flashed to partition B)

12) fastboot reboot

13) Done, android 12, rooted and fully functional

Edit: patched boot to let people skip steps 2 and 3: https://mega.nz/file/bAsQSSzB#XPcVrioHH-F7cD2DfXZvCM7Che6pLktNfosIcCpOeOo

Mine has gone back to non-rooted, locked in fastboot screen. Was rooted and fully functional for a few months, then lost it somehow. Anyway, I would be happy now to just coax it into factory recovery so that I could do a reset on it. The button sequence escapes me.

Anyone remember how to get it into factory reset mode from the fastboot screen?
[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] catzilla:
Sounds like you screwed up boot. Since you are in fastboot, why not flash your rooted boot.img from last time you did this? fastboot flash boot boot.img

Had the same issue weirdly, where after flashing, it booted into a stock and factory resetted state (perhaps wrong slot) and couldn't load any app. Then after flashing again, it worked :D

I got the 12 update and it messed my phone up, so i sent it in for service and the jerks sent me back a new phone with 12 already on it instead of downgrading it to 11. I cant seem to get it to do anything. I side loaded both versions in post #3, but 12 just booted.

Edit, its actually my phone, not sure what they did with it, or if it fixed the issue, cause i want to do everything i can get 12 off of here. So, if you need anything from it, let me know.

Help, I seem to have bricked my phone...

A new security update became available.

Went into Magisk -> uninstall.

Applied update from system options - and the phone rebooted! Now I no longer have root.

Ok, reboot to fastboot and apply boot from original android12 update (magisk_patched-23000_V6RRL.img).

Now I can no longer boot.

I cannot sideload the original android12 update either because:

"Update package is older than the current build, expected a build newer than timestamp 1655370772 but package has timestamp 1650077212 and downgrade not allowed"

I think I need the latest update.zip to extract boot from, does anyone have it? Please!

After attempting the sideload, it only boots to recovery now:

"Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on this device".

Two options: try again and factory data reset.

I am able to get to bootloader with usb cable in + volume down + power

From there, "Reboot bootloader" and then selecting "recovery mode" gives me recovery with regular options, however, so hopefully not all is lost.. Attempting to sideload the same package again results in the same error, and system does not boot. From there I can enter fastbootd as well.

Afraid to try "boot to QMMI", I don't know what that is.

Please help..

I was out at Pizza Hut when the notice came up on my phone that an update was available and carelessly proceeded to approve the update without uninstalling magisk or taking any other precautions. Thought that I'd just figure it out if anything were to go wrong. Ouch!! Been working on it over the holidays trying to unbrick it unsuccessfully. Thankfully, I had a backup phone already rooted and working the way that I wish this phone were working. My advice: watch out for this update, it might break your phone. Mine still accesses fastboot and recovery but I haven't been able to flash any of the zip files available on this forum, so far. Caveat.

any news plz?
[Nokia 8.3 5G (8V 5G UW) Guides, News, & Discussion] nojokeman:
Regarding my previous post #(108), good news – phone’s working again – with root and without any problems, so far.

As I had mentioned, none of the firmware packs available on this forum would take by ADB sideload, and I don’t why. However, the firmware pack available on the Telegram feed: Nokia OTA Repository:

https://android.googleapis.com/packages/ota-api/package/1298531d07d0356d4b320d29222469cafa0b3b79.zip

worked.

Search the telegram messages for “8.3” to be sure to get this one.

Then, I side-loaded it using “adb sideload <filename> available via the factory recovery mode and the system came back up.

To root it, I had to go previous school. Using TWRP that I got from a friend of a friend (it can be searched and found by searching for twrp BGT sprout), I downloaded the magisk zip file for flashing to my SD card, booted the phone via the ADB platform tools using “fastboot boot <twrp image>. Upon the phone booting into twrp, I hit the “install” button, navigated to the flash-able Magisk zip file, and installed it. Upon rebooting, the phone was rooted.

Lessons learned: If the firmware pack version doesn’t match the boot.img used for patching with Magisk, it will break the wifi/telephony function of the phone. In my case, initially when I was temporarily able to flash some of the firmware packs available on the forum, the system would update to newer than the firmware pack and then, figuring that it was still Android 12, I would flash the patched boot image kindly made available by catzilla and come back with an operating system minus the wifi and phone function. What finally worked for me was to sideload the firmware pack mentioned above, download the flashable Magisk zip file to the SD card, and to use temporary twrp to install it.

I was unable to permanently install twrp as the recovery on my phone. When I tried, I always ended up in a situation in which the phone would only startup into twrp, or to fastboot through twrp. I think that it can be done because my research showed than many others experienced the same problem, but their solutions didn’t work for me. Now that I have it working, I hesitate to mess with it anymore. I’ve been on this project about a month already.

Beware the updates.

When sideloading https://android.googleapis.com/packages/ota-api/package/627142c637bf373410e6b8911aeb9b2e65bd5969.zip I received the error that the update package is older than the current build.

With "fastboot oem getversions" I do see the 00WW_1_150 software version though, so I guess it worked.

then in cmd do th commands:

Hello. So a friend of mine had his nokia 8.3 5G bricked by the latest update (SP05 I think). He was on android 12.

After researching here and on other sites I found out how to unlock the bootloader and reinstall android 12 OTA and now it works. I'm currently installing the SP until SP04 (f**k you SP05).

So maybe my post could help someone else who's in the same boat as my friend.

So before starting all of it you need to install ADB and FASTBOOT drivers. You also need to modify the adb.exe file so it can send big size files : https://www.techpowerup.com/forums/threads/large-address-aware.112556/ or https://xdaforums.com/t/q-adb-cant-read-sideload.1990405/post-69648733 . If not, you cannot send the zip file to the phone.

Be sure you have the latest fastboot and adb drivers.

You also need to download the android 10 - 00WW_1_150-B01 full OTA zip: https://android.googleapis.com/packages/ota-api/package/627142c637bf373410e6b8911aeb9b2e65bd5969.zip

After all of this the commands are :

- cmd.exe in admin mode

- put the zip file in the same folder as the adb.exe

- navigate into your adb folder (where adb.exe and android 10 zip file is)

- put your phone into recovery mode

- go to the menu on your phone and do load update via adb

- adb kill-server

- adb root

- adb sideload 627142c637bf373410e6b8911aeb9b2e65bd5969.zip

- wait until it send the zip file to the phone

- even if it tells you it (something like "Update package is older than the current build, expected a build newer than timestamp 1655370772 but package has timestamp 1650077212 and downgrade not allowed" look into the screen and you will have installed 2 of 2)

- very important use menu on the phone and "reboot into bootloader", NOT RESTART PHONE

- download BGT-abl.elf from here https://api.hikaricalyx.com/Firmware/GetProtoABL?project=BGT (or main post)

- fastboot flash abl BGT-abl.elf

- fastboot reboot-bootloader

- fastboot oem unlock-go

- use volume keys to select UNLOCK BOOTLOADER and press the power button to unlock it

- reboot into android 10, connect to wifi, do android update to 12, it works. I've also done the 4 google security patches, not a problem.

Hi all, the prototype ABL for Nokia 8V 5G UW is now released.

Unlike Nokia 8.3:

- Using it requires you to flash FRP partition with OEM unlock flag enabled, or you have OEM unlock option enabled beforehand.
