[Nokia 3.1 Questions & Answers] mn1968:
That is unfortunate! Perhaps, does activating Developer Options allow to select OEM Unlocking and USB Debuging, then running the Unlocking App? To run step 5 of 5 (see NOKIA INSTRUCTIONS below) you would need to have USB Debugging enabled anyway. Nowhere in the instructions is that mentioned.

FYI - Activate Developer Options: Go to Settings>About Phone and tap Build Number 7 times. Back out to access Developer Options.

Also, I do not have this phone but am interested in it. I cannot confirm if any of the advice I am giving will work, but it is what I would try.

NOKIA INSTRUCTIONS

Introduction

Firstly, we need to validate that the phone you would like to unlock is operated by you. There are a few steps to this, so we ask that you carefully follow all instructions. Let’s get started.

To participate, simply complete the following steps:

1.	Please download the Nokia Bootloader Unlocker app. You can download the apk from this link and install the apk on your device. If you don’t understand how to install an apk on your device, please do not unlock the bootloader on your device. Doing so will void your phone's warranty and may cause irreparable damage.

2.	Launch the Nokia Bootloader Unlocker app and fill your email information and click “Submit”.

3.	The app will display a code. Please enter this in the form below along with your email address. Then press "Request to Unlock"

Your bootloader can now be unlocked. Follow the instructions below:

Step 1/5

Check the email you entered during registration. You should receive an email with a message as follows:

Hi, Thanks for requesting the unlocking bootloader. Please download your unlock key from the following link. xxxxxxxxxxxxxxxxxxxxxxxxxx

Download the unlock key and save it as “unlock.key”.

Step 2/5

Power off your device. Once powered off, press and hold the Volume Down button.

Step 3/5

While keeping the Volume Down button pressed, connect the device to the computer via USB cable. The device will boot into “Download mode”. If you have difficulty, try powering up normally, power off the device again and start back from Step 1.

Step 4/5

Download the following fastboot binary for your OS here.

Step 5/5

Open a command prompt:

Windows: Start > cmd

Mac: Applications > Utilities > Terminal.app

Linux: Terminal

Navigate to the directory where the previously downloaded unlock.key file is saved. Then enter the following commands:

fastboot flash unlock unlock.key

fastboot oem unlock

If successful, you should see the below message:

Unlock success!

Then reboot the device by entering the following command:

fastboot reboot

You are done!
[Nokia 3.1 Questions & Answers] VidarPT:
It doesn't work either way. I tried with both those options enabled and disabled but the program always crashes. It's interesting to note that the app itself fails to install through chrome or "Files" app. Gives an error saying "Can't open app". I only managed to install it through ES File Explorer. Could it be because of I bought the phone on a Vodafone store? I can't find the original stock rom to flash, sadly.
[Nokia 3.1 Questions & Answers] mn1968:
I have been researching this and have found that, as of this writing, only the Nokia 8 qualifies for bootloader unlocking. See here. The only thing holding me back from jumping on this Nokia 3.1 is the inability to unlock the bootloader (and maybe the lack of fingerprint sensor.) Hopefully it gets "approved soon".
[Nokia 3.1 Questions & Answers] rufw91:
Currently the oem unlock using the Nokia bootloader unlock only works for Nokia 8
[Nokia 3.1 Questions & Answers] snarfydog:
is there a way to root the 3.1 yet successfully? im a noob at this stuff and don't want to screw my phone.
[Nokia 3.1 Questions & Answers] MilesSeventh:
No, not until Nokia decides to allow users to unlock bootloader.
[Nokia 3.1 Questions & Answers] XSHADOW3:
What about the 3.1 plus. I've already unlocked OEM. I just started looking, thought I'd start here first.
[Nokia 3.1 Questions & Answers] MilesSeventh:
It doesn't matter if you have enabled "OEM unlocking" option in Developer settings, currently Nokia doesn't allow unlocking of bootloader and thus rooting device, unless you are Nokia 8 user. You can try this, but it will crash almost for sure.
[Nokia 3.1 Questions & Answers] Nightseer:
As far as I can tell, my bootloader is unlocked. I am a noob of course, but I have been researching this topic for a couple of months now. I could be mistaken in thinking "upload" mode is it, but I can't seem to figure out the difference. Otherwise, I don't know what to do next.
[Nokia 3.1 Questions & Answers] MilesSeventh:
Can you please tell what did you do exactly?
[Nokia 3.1 Questions & Answers] Nightseer:
To get to "Upload" mode? Assuming it's the same for the 3.1 Plus-maybe I should have specified that-holding power button and volume up during startup will open "Upload" mode.

You can also use adb with the command "reboot bootloader." For that reason, I think it's the bootloader, but I could be wrong.

Sorry if I was a bit misleading and it is totally different on the Nokia 3.1, I was just some kinda hopeful to actually see people talk about it.

Let's get her done

I'm not bringing any sizable programming skills to the table unless somebody wants to teach me real fast.

Hopefully, I bring tidings of great joy. So I got two these Nokia's and they're both locked. to the carrier, Cricket. I suspect they are at least unlawfully locked. . My understanding is you can't lock to used phone especially if it's been sold as a prepaid phone. I believe this falls under the reseller flex policy. I bought it off of eBay from a guy that sells nothing but phones and he's been extremely cagey about what he'll admit to, so I called the carrier. I literally waited an hour and a half on the phone because I am falling asleep and I was on a computer speaker phone so it kept on the time of the call. I only held that long because I had fallen asleep. Anyway since I'm not in a cricket or AT&T customer then don't plan to eitherbe they could care less about me it actually told me they didn't have any information on the phone after I gave them the IMEI number.

My guess is the fcc's not going to do much because it's a trump Administration. So I spent about 45 minutes on the phone with Nokia and well at least they're interesting I think Microsoft paid between 7 and 12 billion to acquire them I recently sold them off for like a box of jujyfruits. Anyway they're committed to customer service so I figure my predicament might give me an in there.

So those unlock codes that it was a link earlier in the post for that's just to unlock the bootloader, right? You know this is a pretty decent phone for a low-end guy I got the newer 3.1 C it's got Cricket's bootloader in bloatware on it,

takes up a ton of space.

I mean it probably won't happen but if Nokia ever goes public again - I think the acquiring companies. Their eye on the prize and they're going to kick some ass. So I'm all in on this let's get this done. If you want I can see what I can do about asking Nokia 4 whatever it's going to take just to keep me a satisfied customer since they know Cricket/ATT isn't following the Obama regs.
[Nokia 3.1 Questions & Answers] Armandruzz:
Oof... It would be beautiful if Nokia customer support could guide us onto rooting this phone.
[Nokia 3.1 Questions & Answers] jeetkml:
its so simple to unlock oem on nokia 3.1 plus. no third app needed. after developer option on -> go to developer option setting -> there is toggle button to on/off developer option , just use that toggle to off it and on it -> press yes for on dev options -> and select oem unlock. that all
[Nokia 3.1 Questions & Answers] yesimxev:
It is pretty straightforward once you have unlocked bootloader (not by Nokia). If you want, you can simply dump boot_a or boot_b with SPflash tool, patch in Magisk app, and reflash.

Otherwise you can use my TWRP (NO TOUCH, and has disabled dm-verity). Please note it's only working on build v3.180, updates not supported - as it was only needed for my project.

[Nokia 3.1 Questions & Answers] Coffinman:
Do not buy this phone unless you want to feel like a farm animal.

Mine just decided not to show me my USB connection menu ever again. So forget putting data on it, by wire anyway.

The "Android Go" (= disabled Android) won't even make new screen pages.

I hope Nokia goes bust and vanishes.
[General Questions and Answers] VoItage:
Hello, nice to met you all, in my first post, I would like to ask if there was a way to open two launchers in one phone, one for the phone and another for when the phone is connected to hdmi/mhl, it's something like Oxi desktop, I want to keep phone as normal and when hdmi is connected to the other screen, in this case, my tv will open another launcher just for it.
[General Questions and Answers] Raiz:
Ok , first download those two launcher , and set one of them as your default launcher . Then , when you connect to HDMI go to settings , apps and search for your second launcher. Click on it and scroll down to Home app ( for Android 8.1 ) and click on it , from here you'll be able to choose your default launcher. If you don't find this , just erease the data of your main launcher and press the home button. There will be a prompt to select your launcher , click on the launcher you want for hdmi .

[Recovery] LeTV Super4 (4th generation) :: All Mstar 6a938 based models supported

The recovery is based on generic aosp recovery. Signature checking is completely disabled, so you can flash any .zip update. The responsibility of what are you flashing is entirely on you. Full busybox with symlinks is integrated, selinux is disabled, root console (uart 115200 8N1) is enabled.

Successfully tested on:

LeTV Smart Home Center (http://www.lemall.com/product/pb.html?ref=cn:syspdf_4) Filename: LetvUpgrade938-SHC.bin

Super 4 X43 Pro (http://www.lemall.com/chao4/x43.html) Filename: LetvUpgrade938.bin

Super 4 Max65 (http://www.lemall.com/max65new.html) Filename: LetvUpgrade938-SHC.bin

How to flash recovery?

- TV is off

- Extract LetvUpgrade938.bin from the archive provided. Rename the file according your model default ROM name. Most Super4 TV models use LetvUpgrade938.bin , but other options are: LetvUpgrade938-X4N.bin (M-series), LetvUpgrade938-SHC.bin If you do not know the exact file name just try all options one by one.

- Put the bin file into the root folder of a usb drive and insert it to the TV

- Stay in front of the TV and point the remote to the center of the TV and press: SETTINGS, VOL+, VOL-, CH-, CH+, POWER (each button should be hold during 1-2 seconds)

- TV will boot up and you'll get a blue progress bar with green text under the bar. After flashing the TV turns itself off.

- If the file name is wrong or there are some errors during flashing you will get red error message under the progress bar. Just power off your tv and you can start again with other file name.

- Important step Do not boot Android after flashing the bin file! Enter the recovery and flash UPDATE-Recovery-After-Install.zip The package will disable letv recovery auto-update mechanism. Otherwise every time Android boots it will wipe and restore letv stock recovery partition, and you will have to flash custom recovery again.

How to enter recovery mode?

- If you do not have buttons on the TV you can use remote. Press: SETTINGS, VOL+, VOL-, CH+, CH-, POWER

- If your TV has a separate soundbar unit with buttons, then you can enter recovery mode by holding Plus (Volume UP) button and power on tv by switch or power supply.

Please, share your exact model name, file name you used and a link on the product page on leeco website (it is optional), if you got success, so I can add it to the list.

I have the Super4 X43-Pro as well running on the US Rom. Was able to flash the recovery bin without any issues. But I am unable to boot into recovery using (SETTINGS, VOL+, VOL-, CH+, CH-, POWER), using this combination takes me to the LeEco screen and stays still on it :confused:

Am I doing something wrong? Tried a couple of times now with no luck.

Did you flash the zip through recovery (without switching the tv) on just after flashing the bin? I just followed the steps exactly as directed by dipcore and I was able to get everything right on second attempt.

[MENTION=6810881]dipcore[/MENTION] provided me with another recover.bin image and that worked like a charm. I think the US Rom has something to it. I am so excited that he responded with a new file in literally 15 mins or so - hatsoff :angel:

My aim is now to flash the China 6.5 Rom and have GApps installed as well. Loved the 6.5 Rom but there is too much of Chinese bloatware (that I can remove now with root), install the play store and have SunNxt hopefully working as well along with Youtube :fingers-crossed:
[Android Software Development] jsbi:
Here's an update of my experience with the 2 different ROMS released by LeEco for x43Pro (Comaprision for feature of the China EUI 6.5 and US ROM for x43Pro).

China 6.5 ROM:

Pros:

Has a lot of options (so also a lot of bloatware).

Very stable and slick as well.

Picture and sound seems to be much better (not sure if that is my perception).

Was successful in installing Google PlayStore and making it work.

Can switch off screen and also the Le button (a.k.a. shortcut) on remote works.

Cons:

A little Chinese language here and there even after changing to English (but totally acceptable).

Youtube had issues playing 4k and somethimes even HD videos (blank screen) and audio was mostly not there.

Voice options don't work.

US ROM:

Pros:

Pre-installed Google Play store and all GApps work fine including 4k Youtube.

Minimal UI and no bloatware except some pre-installed apps like DirectNow, Fandor, etc.

Voice commands work fine.

Cons:

Shortcut button on remote doesnot work (I think an app can help mitigate this).

No memory & junk file cleaner inbuilt.

Need to hold power button to shutdown TV, else it goes to sleep - sometimes wake from sleep doesnot work as well.

How do you use stock recovery after enabling your custom recovery?
[Android Software Development] Logix:
you dont he was saying to flash stock roms use stock recovery you gotta flash the whole original bin file to get stock recovery back (unless someone has a flashable stock recovery avil?)
[Android Software Development] dipcore:
Just create a simple update zip with stock recovery image in it. Other option is just flash full stock update zip.

BTW if you have trouble with flashing stock zip then just open updater-script which is located at update.zip/META-INF/com/google/android/updater-script

and remove first lines started with getprop

i.e.

```getprop("ro.product.board") == "mangosteen" || abort("This package is for "mangosteen" devices; this is a "" + getprop("ro.product.board") + "".");```

then pack it back to zip and you will be able to flash it via my recovery.

Thanks, I just wanted to be sure. I already bricked my TV once 6 months ago and had to get the entire motherboard replaced (unrelated to this recovery).

I was trying to enable 3D and set the TV type to something else in the factory menu and support wouldn't give me a bin file to flash/recover. Now I know more about the TV and have the *.bins I believe you could recover from such a mishap.

It's best to stay away from 99% of the factory menu.

Hello... I have been trying to follow steps on how to setup my tv with the latest Chinese fw and patch on telegram but seems hard to figure out with everyone seems to chime in with their own problems.

I have the latest USA version fw and I have the Super4 X55 and want the correct steps to follow to set my tv up with the latest fw and patches without worrying about bricks or issues.

What seems confusing is some people are chiming in that leanback launcher needs installed then another person chimes in with something else...it gets confusing and redundant on telegram.

Their is latest version 0715 and patch and an ads free patch. Some people include root, some people saying it's not necessary.

Just really need simple complete guide that allows installation one complete step at a time.

My TV installs the recovery and the custom recovery and the patch for the recovery fine... but I always get a bootloop (TV turns off, or standby?, when booting, will not boot.) when trying to install SuperSU, or the "No Signature Checking" zip file. I had to use "letv938_recovery_us_v0.0.2" because the main one was failing.

I am attempting to get root so that I can remove those pesky Leeco apps and change the launcher.

I am on an X55 USA.

Any help would be greatly appreciated.
