[Noob] Just bought a Zuk Z2 Plus - ROM help needed please!

I am unsure whether my phone (which is being delivered from Gearbest) will have google play store and google sync etc all installed and working. If I don't have all of that installed + working I am going to try and flash a ROM (probably unofficial CM14.1) from here.
Now, when I went to see how to unlock the bootloader, the guide had a lot of chinese writing, so I couldn't understand what I was supposed to do... Can someone explain in english how I am supposed to unlock the bootloader?
The following is a snippet that I did not understand from the guide. Link : https://forum.xda-developers.com/zuk-z2-pro/development/how-bootloader-zuk-z2-pro-t3415392

Not sure how far you've gotten following that guide. It's very good in pointing you where you need to look but it assumes that you do have a bit of knowledge to follow the basic steps without given a full explanation of every step you need to take.
With that in mind, I loaded a custom ROM in my phone just last week and here's the steps and the pitfalls you need to avoid:
This is the guide I used: http://zukfans.eu/community/threads/zuk-z2-bootloader-unlock.62/
So grab your phone S/N, install ADB and Fastboot on your PC, and install the Google and ZUK drivers.
Things to note:
If you're on Windows 8/10, you might have issues with driver signing enforcement. Bizzarely the drivers from Lenovo for the ZUK are unsigned and Windows does not like that. So you might need to disable this function. Thankfully, it's rather painless. http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
Now to unlock the bootloader. You'll need to go to http://developer.zuk.com/bootloader but first you'll need to register to the site. I'm assuming that you're not in China or have a chinese SIM lying around so you'll need to register using email, which can be done here: https://passport.zuk.com/wauthen3/w...lenovoid.thirdname=null&lenovoid.qrstate=null
Once you register, fill in the bootloader unlock form and you'll get an email with some Chinese writing, this is unimportant. Look at the attachment to that email and you'll find a unlock_bootloader.img file. Download it and you're in business.
Now I ran into trouble sending fastboot commands to my phone, just wouldn't be detected for some reason, no clue why. But I found this tool by mauronofrio: https://forum.xda-developers.com/zu...ol-tool-one-driversunlocktwrpfactory-t3432782 - works like a charm, you can use it to unlock the bootloader and then install TWRP on your phone.
Once you have TWRP then you can install whatever ROM that tickles your fancy, no problem. Personally I'm running Resurrection Remix by fedor917. I tried CM14.1 but it's not stable enough for me and I much prefer RR. Plus it's Marshmallow so xposed works fine on it and plenty other stuff that hasn't reached Nougat yet. I really want Nougat-based Resurrection Remix on this phone and I've been working at porting it, but it's the first time I do this so it's quite a steep learning curve.

Thank you for replying.
I have found a simpler guide I believe...

There is no mention of unlocking the bootloader.
Do i not have to unlock the bootloader then?

That is just for installing the stock ROM (ZUI) so for that you don't need to unlock your bootloader, but if you want to install a custom ROM (Cyanogenmod, MIUI, Resurrection Remix, etc.) you do need to unlock the bootloader and the install process is much simpler (unlock bootloader -> install TWRP -> wipe & install whatever ROM .zip file you want).

Ah okay, thanks.
I've found a good tutorial I think. It seems more simple compared to using the qfil qualcom software stuff. What do you reckon? I've seen other people (can't remember what thread exactly) suggesting miflash to be used as well.

[Unlock Bl] [TWRP] Guide To Unlock Bootloader Of Meizu Pro 7 (p25)

Note:- Credits To this guide goes to {Diablosss}
GUIDE FOR UNLOCKING BOOTLOADER OF MEIZU PRO 7
(Sorry for the inconvenience, but there are some issues in posting pictures. Therefore requesting you to please check the attached files for images)
This guide can also work with many other Meizu devices. Checked on 15, 16 all options (s, t, x) and on Pro7​I post the archive and instructions in pictures.
Step 1: Download. Unpack. Run meizublunlocker.exe
meizublunlocker:-https://drive.google.com/open?id=1yEm_vZo4rsqEtii279AU6l1mBajiSPQ2
See Image 1 in Attachments.
Step 2:-We connect the phone to the computer in fastboot mode (hold down the Vol. Down and power buttons), click refresh. The program must identify the device.
See Image 2 in Attachments.
Step 3ress CheckBL to check bootloader status.
See Image 3 in Attachments.
Step 4:-Click the Create Request button. This will create a file with the end of req.dat in the folder with this program
We send it to the e-mail [email protected] and wait for the response file to unlock the bootloader.
(This takes usually 1 week to receive the unlocked file, but you can donate to get the file within 3 hours)
See Image 4 in Attachments.
Step 5:- After we received the unlock file with the end of res.dat, click UnlockBL and select the resulting file.
See Image 5 in Attachments.
If the file is correct then get this answer
See Image 6 in Attachments.
That's It. We successfully Unlocked the Bootloader.
Now the next thing is to install the TWRP in our Device. ( Further credits goes to{ sergpolov} )​
Step 1: Download and install "adb_run"
adb run:-https://drive.google.com/open?id=1y4wdL53-P7mybKsj5XeimHRoMSpokMkQ
Step 2:- Download the required Files.
Stock Recovery Pro 7:-https://drive.google.com/open?id=1e2tRdqLi5jsT8J854RMcIA-jvZyR7xhT
Twrp Pro 7:-https://drive.google.com/open?id=1uYOT9HGractYuoJvRidgAgh8IBLhzFtu
Step 3:-We load the phone into fastboot mode, flash through the fastboot the recovery you need.
Launch the application shortcut
Step 4:-Click "3" - go to fastboot mode
See Image 7 in Attachments.
Step 5:-Click "3" - recovery
See Image 8 in Attachments.
Step 6:-Here we select the recovery file: - in the window that opens, we throw the file itself and close the window with the file and press any button.
See Image 9 in Attachments.
The process has begun.
See Image 10 in Attachments.
Step 7:- Choose "Y" and "Enter"
See Image 11 in Attachments.
The recovery firmware process is over!
Next Few Steps are Extremely Important , so follow with caution!​Step 8:-Reboot into Recovery Mode(hold down "Power" and hold, as soon as the screen goes blank, hold down the second button "Volume +" - hold it until vibration and release "Power", and after it release the button "Volume +")
Step 9:-To disable encryption of the "Data" section (who installs TWRP), we immediately flash the zip archive - tool-root_unlock-Testing-Pro7.zip
(disables encryption of the "Data" section, disables Boot and Recovery checks, installs Magisk and disables system root) and reboot into the system.)
tool-root_unlock-Testing-Pro7.zip:-https://drive.google.com/open?id=1a3Gyyuoo2Jv3EN7EWPwj389tXorSwkxT
Attention ! When installing custom recovery (TWRP) on your device, for the full TWRP functionality, you should format the internal memory (Data section) of the device using TWRP itself, since the "Data" section on Meizu smartphones is encrypted, I highly recommend it before installing custom recovery , on creating backups using the internal Flyme firmware (after creating the backup, it is located in the "backup" folder of the internal drive), as well as copying all the necessary data from the phone’s internal memory to the computer!
NOTE:-No One shall be responsible to any damage ocurring to your device

Doubts and queries are welcomed .

Hi, but doesn't this only work on Qualcomm processors? How does it work on a Meizu Pro 7 which is a Mediatek? I tried it on my Meizu M5C and it doesn't work.

Yeah you r right and this guide is also taken from meizu 16th only, but this is tested now because qualcomm devices requires port_traces.txt and unlocked bl.bin files whereas for pro 7 we are using to res.dat which uses fastboot driven commands only.. Thats why it got successfull. I am also posting pictures for proof. (Shared by diabloss).

i know you have already tried this method with your device and it didnt worked. I am not sure that m5c will get another method in future or not. Bcoz we also got lucky with pro 7 that it got successful by the help of guide ported from Meizu 16TH a Qualcomm device.

i am not sure about this but yeah 5$ is not a big cost for this. Like sincerely there is no other verified method to work and unlocking bootloader gives u many advantages. You can have magisk now and various other thing . You can directly flash service firmware now by flash tool. Custom roms are also there. Like 5$ dollars for a mediatek device is reasonable.

In this TWRP, could we install anny official ROM (Global or Chinese) in it's standard form (update.zip)? Or some file modification in the zip archive is required?

Some users reported that they can directly install the official update zip. But i would recommend you to modify the updater script before flashing. You can request your firmware to make it TWRP flashable we can help you with this.

Well, it would be nice if some very talented enthusiast developer or team of devs would build a custom ROM based on Android 8 or higher (if it's possible, of course).
I saw there is single custom ROM, AOSP, but it's still based on Nougat, like stock Flyme. This makes it uninteresting for me, because it brings nothing new over already very-good-full-of-options Flyme ROM based on Android 7.0.
Maybe time will bring us custom ROMs based on a newer Android, at least Oreo.

theoretically its not possible to update android version.. Because we dont have the source code to develop a higher version kernel .. But still there is a hope to port a rom based on android 8 but cant sure for stability.

I remember that Lenovo P2 smarthone officially stopped at Android 7 but people could install different custom Oreo, Pie and Q ROMs. This means that Lenovo published the source code?

Lenovo P2 is a snapdragon device. The source code and device tree can be found easily. Unlike mediatek , snapdragon never hides such things that's why the development is high on SD devices. Mediatek released kernel sources till Helio p10 then never disclosed anything. For higher android version roms we have to port kernel to higher version. Meizu pro 7 is right now on 4.4.15 kernel ver. For higher version we need kernel of 4.4.15+. I hope i cleared your doubts.

So, it's all about the source code, kernel sources and so on.
From my point of view (and my knowledge), there are two major steps or two issues that need to be addressed to successfully develop ROMs and kernels for a phone:
1. As you said, the source code must be released publicly.
2. The bootloader must be unlocked (or easy to unlock), for all these mods and kernels to be installed through a custom recovery (IF a custom recovery is developed).
Please correct me if I'm wrong (I'm seeing these things from consumer/user point of view, not like a programmer/developer/coder).

Question Difference between install via TWRP and without TWRP

Hi everyone! I'm pretty new to android. In fact, Mi 11 is my first android phone. Since the official EU ROM for Mi 11 won't be revealed until Feb 8th, and currently we don't have the TWRP for Mi 11, I'm wondering what is the difference between installing the EU ROM with TWRP and without it? After checking the guide, it looks like if installing with the TWRP, then we can use OTA to install future updates. Other than that, are there any major differences? Also, because I basically have no experience with android, I'm slightly worried about bricking the device when installing the EU ROM. Will it be safer to wait until we have the TWRP for Mi 11?
One last question, anyone with experience of using Xiaomitool V2? It looks like a decent tool that can automate most of the installation process.
Thanks!

Without a Custom Recovery available it's riskier to flash, if you don't know what you are doing you can get yourself a nice brick.

You don't really need to worry about twrp, it's only good for backing up and flashing stuff without a PC.
You can still soft brick the phone with TWRP.
Hard bricking a phone in my opinion is pretty much impossible. The important part is having an unlocked bootloader, fastboot and Google USB drivers installed.
You're also better off installing the Xiaomi EU ROM instead of waiting for the global version. The guide is available and is basically a one click install so can't really go wrong.

Thanks for explaining everything! Do I need to install adb and other drivers beforehand? I assume the ROM zip doesn't include those drivers.

Minimal ADB and Fastboot Tool. That's what you need. Google and download it

It is really very easy to flash the xiaomi.eu via Fastboot if you follow the instructions. Updating via script also works flawlessly.

I used the ADB and Fastboot tools given above. Likewise the Mi Unlock Tool. If everything is displayed correctly in the device manager when connecting the Mi 11 with China ROM and activated USB debugging, everything will be fine. I use Windows 10 x64 myself and even connected it to a USB 3 hub. But it should definitely be a high quality USB cable.

Legit Nokia 7 Plus Bootloader Unlock?

Hi,
I just happened to google how to unlock Nokia 7 Plus' bootloader again and stumbled upon this site:
[Guide] How to unlock the bootloader on Nokia Android Phones for free
Detailed guide to help you unlock the bootloader of your Nokia Android device. You can unlock bootloader on many Nokia smartphones, including Nokia 7 Plus, Nokia 8, Nokia 8 Sirocco, Nokia 8.1, Nokia 7, Nokia 6, Nokia 6.1, Nokia 5, Nokia 2, Nokia 2.1. etc.
www.techmesto.com
It was updated today with a free way to generate bootloader unlock keys for Nokia 7 Plus apparently. Now I can't test this myself at the moment (in a week at earliest), but do you think this is legit?
At least I can generate a code apparently, so this part is actually free.

Hello,
has anyone tried this unlocker, because I'd like to use it, but since I use my nokia 7 plus as my primary phone I'd like to have some confirmations before using it

I use my Nokia 7 Plus as primary phone as well, but I guess I'll just risk it
However, I can't promise anything here. Hopefully I will get around to it within the coming week.

I tried it yesterday and it work flawlessly.
Just follow the steps on the page, I had no issues unlocking the bootloader.
That being said, I nearly bricked my device when trying to flash Lineage OS onto it (because all TWRP and Lineage OS step by step guides seem to be out of date?), but this guide helped me get back to stock: https://forum.xda-developers.com/t/...m-flash-tool-nokia-7-plus-b2n_sprout.4023961/
Might keep it handy if you are like me

Thanks for the useful infos.
I suppose I will unlock my phone in the upcomming months but right now I just factory resetted it and it's working almost nicely.
I really want to unlock and flash a custom rom on my phone, because the stock rom it's buggy and tends to have some performance issues, but right now if I mess with it I can't afford to change the phone so I guess I'll have to wait.

Yeah, the tutorials seem to be a little outdated...
In general, follow this guide here (its from the same person that created the official twrp.me site I believe):
[CLOSED][OFFICIAL] TWRP 3.4.0-0 | Team Win Recovery Project | Nokia 7 Plus | Onyx |
Note - Iam Not Responsible for bricked devices About Team win recovery project TWRP is an open source, community project. TWRP development is done by roughly 4 people at this point. We also have a large support community with many people who...
forum.xda-developers.com
I wasn't sure if I have a OOB or POB device, but I haven't had any issues using both (currently using OOB since I'm pretty sure my Nokia 7 Plus is that old )
Secondly, what the instruction somehow failed to mention is how to get the install.zip. It is on their sourceforge page in a subfolder:
B2N_sprout - Browse /TWRP-TEN/OOB at SourceForge.net
sourceforge.net
This is for the OOB variant, you can replace OOB at the end with POB to get the other files
You can verify, that I'm sending you the right link by following the links from the forum post to download the image to boot from. For example:
https://sourceforge.net/projects/b2n-sprout/files/TWRP-TEN/POB/twrp-3.4.0-0-B2N_sprout-POB-10.0-20200829.img/download
Now you can just remove the "twrp-3.4.0-0-B2N_sprout-POB-10.0-20200829.img/download" part of the URL and you get to the folder where all the other images are located. Download the latest "twrp-installer-*.zip" for your device and install it.

This is great, thank you so much! I can also boot from both OOB and POB, will try this out later today
EDIT: worked like a charm. Thanks again!

Great! Glad I could help!

Hi @Znert, did you use TWRP for Android 10 or Android 11?
Another question: can I unlock the bootloader of a Nokia 7+ on Android 10?
Thank you again.

I use the Android 10 version, but I'm not sure what the difference is anyways (it's a bootloader, shouldn't that be OS independent?)
Regarding your second question, yes, I unlocked my bootloader with the latest official stock ROM (so Android 10).

Yes that's what I thought also... Maybe we need to use the Android 11 version to install a Android 11 ROM.
Now I see there is a new version of TWRP 3.5.2 on the official website.

Can you tell me, has unlocking bootloader deleted your apps and data?
In my experience with every older fone, it does format it, but i wanna make sure.
Thanks in advance!

Yes, unlocking the bootloader will wipe your phone. As far as I know, this is true for all Android phones.

In the link they give you clear instructions of what to do. They provide the application (windows,not sure if there's one for linux), and they give the drivers so you dont have to go looking for it. PLEASE READ THE GITHUB INSTRUCTIONS CAREFULLY. They have a compatibility list, so just make sure you have the correct chipset,and if you do just follow the instructions
HOWEVER, TAKE YOUR TIME AND DO NOT RUSH.
If you get stuck or dont understand here is a visual representation of it being done.
I WILL NOT TAKE ANY RESPONSIBILITY FOR DEVICES BEING HARD/SOFT BRICKED OR ANY OTHER PROBLEMS YOU MIGHT OVERCOME.

I can confirm: Just unlocked my P10 lite with PotatoeNV about 2 hours ago. All in all its easy. Hardest part is opening the case.

Enjoy rooting, please note that flashing unsupported roms can make it bootloop A LOT especially if you dont know what youre doing, i havent tried flashing gsi roms either, but please be careful because it is very easy to brick your device

Thanls for warning. I already unlocked/rooted more than a dozend different devices, mostly Samsung, Sony, Motorola. Never had to disassemble a phone before to do so.
Just flashed the crDroid image, seems to work finde. Sadly not many roms to choose from. Had hoped for a pure CM at least Android 11. Any suggestions?
