Has anyone tried Unlocking bootloader / Custom recovery / Root ? - Lenovo Yoga Book Questions & Answers

I would really appreciate it if someone who owns the tablet could:
1. Check if there is a "enable oem unlock" option under developer settings.
2. Try installing twrp,
3. Flashing Su.
I imagine whether the bootloader can be unlocked will be make or break for many people.
Thank you

yes the option is there and the bootloader can be easily unlocked using fastboot. i have already tried it and locked it again.
i don't think it will be wise to install a recovery which hasn't been ported to the device before.

Thank you for that! I guess I took having a TWRP port for my device as granted.

oem unlock is supported.
I can't find a suitable TWRP yet.

What about now ? If it exists, could somebody notices me ? Thanks ~

Revert back to locked state after unofficial unlock (Redmi note 3 pro/SD)

Hi All, I have unlocked the bootloader the unnofical way and i am on global 7.1.7.0(LHOMICL) with twrp and root.
I now have recieved the official sms to unlock from xiaomi.
Already i had to open the phone 3 times to get into edl mode. I really dont wont to open the phone agian.
When i try to unlock the tool answers no need to unlock. I think this is because i flashed the adapted emmc_appsboot.mbn and boot.img thru fastboot.
Do i have to change te rom to another version before i try thru edl or fastboot? What is the best procedure to official unlock now because i read a lot of bricks if they try to revert back to original state.
Can some one give me a detailed guide? Thanx in advance.
You need to flash a fully stock edl ROM on top of your current setup.
This will wipe out your hacked bootloader and throw the original (still locked) one back onto your device.
Then just unlock as usual. I did the procedure myself today already as I got my unlock notification today as well.
Ok thnx for the info. I have changed this global rom 7.1.7.0 in great extend and dont wont to lose this setup.
So can I backup my current setup with twrp with the hacked bootloader.
Flash the complete global 7.1.7.0 in edl mode. Unlock with the unlock tool.
Root the rom and install twrp.
After this can i restore the backup with the hacked bootloader with twrp?
I dont know how the unlock tool of xiaomi works, so i could leave the official bootloader in place when i do the restore with twrp and only replace system and data partition or can i flash all the parts back with twrp to keep the unlock?
Wich procedure will keep the official unlock in place or will this unlock stick always?

please give a detailed tutorial how to do it. I am now in AOSP with unofficially unlocked bootloader. How to relock it again to unlock officially?
Relock Bootloader
I see many asking how to Relock Bootloader, especially those who had unlocked unofficially.
The steps to be followed are following:
(1) Turn on USB debugging for your phone;
Go to Settings -- About Phone --> Touch 7 times on "MIUI version" to Enable Developer Options.
Now go to Settings - Additional Settings - Developer Options --> USB debugging.
Enable USB Debugging and Connect to PC.
(2) Download Fastboot ROM (file extension .tgz or .tar) from
Code:
http://en.miui.com/a-234.html
(3) Boot into EDL
adb devices (to check it's connected)
adb reboot edl
(4) Use MI Flash Tool to Flash the Fastboot ROM
PS: It is assumed that person knows how to get drivers installed for phone if not already, use ADB command as well as know MI Flash Tool basics.
@BRoy_98 @ioosis @davegrond : hope this helps.
@MrColdbird Thanks for the tip

On MiFlash, select folder of Fastboot ROM, then click on Advanced, and in fastboot script select flash_all_lock.bat. After it, close MiFlash then open it again and check in advanced if flash_all_lock.bat comes selected. If yes, close advanced box and flash ROM. Don't forget to close and open MiFlash after choose flash_all_lock.bat script, it's important step. And you can do it in Fastboot mode, don't need to go to EDL mode to flash the ROM.

warranty
does rooting redmi note 3 void warranty bcuz it has a locked bootloader and cannot root without unlocking it ????
and can we lock bootloader again for warranty claims ????
plzz help ???
ty.
Why can't we directly update the device..
Like after flashing miui ROM (7.1)then installing (8.1)....will the bootloader get locked....
?....somebody have any idea place help out
Q. Can the device be rooted without voiding warranty?
A. Yes, by unlocking the BL unofficially.
Q. Once rooted and on MiUI, can I update using Updater?
A. No! You'll lock your BL and end up in a bootloop. Instead, use the updater to download the zip file, reboot into recovery (TWRP or ZCX) flash the zip first and then the universal boot.img patched/lazy flasher and reboot to system.
I followed the method mentioned in the replies to relock the bootloader, i.e, flashed the fastboot rom in edl mode
But for some strange reason, when I entered the fastboot mode and checked whether the bootloader is locked or not by "fastboot oem device-info", it said "Device Unlocked: True"
The main problem came when I booted into the ROM; It broke all kinds of wireless connections. The wifi malfunctioned, the phone wouldn't read the SIM cards etc.
Is there a solution? Please help
Thanks

That twrp is for a different device. I wouldn't flash it unless you have a backup of your boot/recovery or stock firmware for your device

The only difference is that F has no Modem and SIM Slot for mobile Data but it works fine.
I only use it to root the device without actually flashing it.
Just put the twrp image in your ADB Folder on your PC, then run fastboot with the command:
Fastboot boot twrp.img
This uploads twrp on your device and boots it to twrp. You can leave the system recovery untouched and flash supersu for rooting.
The bootloader has to be unlocked of course.

No, no. You have to unluck it via fatboot as well.
1. Enable Developer Options
2. Enable "OEM unlocking" Option in there
3. Reboot to Bootloader (Restart and hold down Volume down)
4. Run fastboot oem unlock-go
Next, the Android Bot and a process Bar appears on the tablet and does it's thing. Once that's finished the Tablet restarts and enters the initial Android Setup Screen. So it unlocks the bootloader but ALSO performs a factory reset.

Yes, I have the YogaTab 3 (X50F). But there probably won't be any harm done unlocking the device and booting (not flashing) from the afore mentioned twrp.img.

Brilliant! Thank you very much. Just got this Tab 3 yesterday and love it. Will love it even more with root+adaway.
It works great. I used adb & fast boot to unlock the bootloader & then boot from twrp image on PC and install SuperSu. Have been using Samsung for a long time but fast boot is much nicer, especially being able to boot a recovery without modifying partitions or filesystems on the device.

How to downgrade from Android 7.1.1 Beta (Build NPF26F)

Hey guys, so I bought a second hand Nexus 6P, and it was running the latest android beta.
Is there anyway for me to rollback or downgrade the version, so that I can unlock boot loader, and root the device?
I'm interested in installing this rom

I don't run the previews, so forgive me if I'm missing something here, but.. why do you need to downgrade to unlock the bootloader? Do the previews not have the "OEM Unlocking" option in developer settings? All you need to do to is enable that and then plug it in to a PC and use "fastboot flashing unlock" to unlock the bootloader. That will wipe the entire phone, including internal storage. Then just fastboot a custom recovery and install your ROM of choice.
If the previews don't have the OEM unlocking option, then log into your Gmail account on the 6P and then visit Android.com/beta and it should show your device enrolled in the beta, select unenroll. This will also wipe all data including internal storage. From there you'd go back to my first paragraph.
Read this and familiarize yourself with it and you're good to go!

Hopefully you were able to figure it out! But like you discovered, it does have an OEM unlocking option. I'm running the dev preview, and rooting is just as easy. If you haven't found any guides here's what you need to do.
Also, make sure you also turn on USB Debugging in your developer settings.
If you've already unlocked your phone, then you already have adb set up. In the case that you don't, install adb on your computer. This tool ( forum.xda-developers.com/showthread.php?t=2588979 ) is very easy to use, although there are other ways to get adb. Run it and select yes to all to install adb. You access adb through your cmd.
1) Download TWRP (custom recovery) from here - dl.twrp.me/angler/
2) Download SuperSU onto your phone from here - download.chainfire.eu/1014/SuperSU/SR5-SuperSU-v2.78-SR5-20161130091551.zip
3) Put your phone into fastboot. Power down and then hold power and volume down until fastboot pops up. Plug into your pc and then open command prompt.
4) Type " fastboot flash recovery * ". The * should be replaced with the location of the file and then the file name such as C:\Users\Kris\Desktop\twrp-3.0.2-2-angler.img
then hit enter and it should write your recovery.
5) Use your volume down button to scroll to the tab that says recovery. Hit your power button to boot into recovery.
6) You'll get a popup and go ahead and swipe to allow your system to be modified. Tap on the "Install" tab in the top left. Locate the SuperSU zip and select it. Swipe to flash it.
7) Once that's completed hit reboot and you're successfully rooted!

Can't unlock bootloader, can't finish OS setup

So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

Locked out of - Android Oreo 8.1 - Forgot PIN - Motorola G5 Plus

I am using Andriod Oreo. Im locked out of my phone. I use a lock screen PIN. My phone says, with 3 more wrong attempts, my phone will be wiped. I would like to recover my data.(I do not have a custom recovery installed)
Here's what I have done till now.
1. I have installed adb and fastboot.
2. My device is recognized under fastboot while my android is in the System boot menu.
3. My device is not recognized under adb.
4. Before getting locked out of my phone, earlier, I have tried enabling "developer options" and "usb debugging" as well. I think both should be enabled. (I am not sure though)
5. I have tried using apps like mobogenie and moborobo as well. They don't have the latest oreo support. Even Dr.Fone doesn't support my device.
My device details: Moto G5 plus :with Android Oreo 8.1.0 update.
Guidance of any sort will be very helpful.
Thanks in Advance,
Shaen
Ok so you have fastboot. Running "fastboot devices" shows device?
If so, download latest twrp and "fastboot flash recovery twrp.img" (or whatever yours is named as, I usually rename mine to twrp).
After twrp is installed, flash the unlock lockscreen zip:

Easy, flash the zip to unlock lockscreen.
I you cannot get twrp flashed or use adb/fastboot, simply boot into stock recovery (power +volume -) and reset phone. Sorry, but if you alll out of options, you have to factory reset.

Thank you for your reply.
I do not have twrp installed. I am not able to use adb. But I am able to use fastboot.
With the above mentioned, is there a way where I can either bypass the lock screen or I can recover my data.
And, Sorry, i do not understand "flash the zip to unlock lockscreen." , being an amateur.
Thanks again,
Shaen

Sorry, I changed my post after you had seen it.
Ok so you have fastboot. Running "fastboot devices" shows device?

Make sure you have the Moto drivers installed on pc.
If you have issues with fastboot not flashing twrp, use this one, it has never failed me:

You would have to unlock bootloader.
First try this. Uninstall the fastboot/adb setup you have, if it is an installer one. And install the one I linked above. Now try adb again with device booted.
With this adb installer, you can simply open a command prompt and type "adb devices". It's a system wide adb install.
If you still have no adb, you have only two options. 1) unlock bootloader and do as I said above or, 2) factory reset in stock recovery and lose data.

Sure, Will definitely try this out and let you know.
Also, in the point 1 you have mentioned, is there a way to unlock bootloader without wiping data?

Additional question:
Thanks for your help and I am following the steps mentioned.
It's on my mind that USB debugging might not be enabled. Sorry to put this now.
I thought you should know this. If this changes anything, please let me know.
If it is mandatory, is there a way to enable USB debugging through fastboot.

Shaen

As far as I am aware, there is no way to enable adb other than to toggle it within the system.

Hi, Here's and intermediate update. And a doubt as well.
I have downloaded the 15 seconds installer from :
https://androidmtk.com/download-15-seconds-adb-installer
https://androiddatahost.com/293a2
Installation is completed.
Also I have downloaded and installed the drivers from : https://forum.xda-developers.com/g5-plus/how-to/how-to-lock-bootloader-potter-version-t3694952
The wizard is completed.
But I don't see the drivers in device manager. How do I know if the drivers are installed properly.
Thanks,
Shaen

I tried again.
I don't have "Android" itself in the device manager list.
Is there something I am missing ?
My is under Portable Devices -> MTP USB Device

If you can't get twrp or adb, there is little chance of saving your files. You eventually have to factory reset and in future have files on SD card. Because your bootloader is locked, you cannot unlock to put twrp on device because that will also reset phone. Your out of options here.

You need adb debugging enabled as he shows in the YouTube link you posted. You have no way to do that. Also to unlock bootloader, you need the other developer option enabled called "OEM unlocking".
