Need help, after downgrade and official update - Moto G4 Plus Questions & Answers

Folks, after a successful downgrade to 6.01 and re-lock the bootloader, i can install all ota's, but the one thing is, that the device will always stays on bootloader after reboot. Right now, i am on the latest MM and will update now to N. Everything works fine. This device must be locked.
I need manually press "START" to reboot into system or recovery mode.
I want to stay on originally software. How can this issue be fixed?

Try connecting your device to your computer, then whilst your device is at the bootloader, in the adb terminal on your computer type 'fastboot oem fb_mode_clear' (without quotes). This may allow your device to reboot properly.

Good job, works, right now
After the latest update to 7.0/NPJ25.93-14/16 it shows instead logo, ID=Bad key, this device is unlocked bla bla bla, but it isn't. Once i did this serveral month ago, it works but not now. MM does not shows a bad key.
i know i can flash a logo to cover this but it should be in original state. Screenshots follows_

No need to worry about,

Just ignore it, it's nothing..

How to get into flashing/recovery mode

1) Turn off and remove battery
2)Put the battery back in and immediately hold the back button
3) Plug in the USB cable while still holding the back button
4)Your screen will remain black, but its in recovery mode, and the flashing software should detect it
Source: Sony Update Service, I installed it and it told me to do just that to get into the recovery mode
Looks like were one step closer into getting the X10 rooted
I'm afraid this doesn't work

It does - it just doesn't display the things we are used to with HTC phones for instance.
This is SE's standard flashing method(and recovery mode). It's the same for their WinMo phones and for Symbian.
It puts the phone in a special flash mode ready to accept a new ROM/flash.
As OP mentioned the screen will remain black throughout the process.
shud try fastboot when its in flash mode..
Code:
fastboot devices
or
Code:
fastboot boot randomrecovery.img

Yes. You can backup sms from the Messaging application by pressing the menu-button while in thread mode. And use MyBackup to backup settings, apps and everything you need on the SD-card or online.
Would this still work if the phone isn't being recognized by the computer? (correct drivers etc are installed).
I have an xperia Ray, so I assume it's the same method... I get no response from plugging it into usb or charger, it won't turn on, although sometimes if I hold the power button it gives a brief vibration. I think it might be bricked :-/

tried turning s-off, phone keeps rebooting :(

All commands typed into terminal emulator were double checked and were typed correctly, i do have root and S OFF but it keeps rebooting!!

I can't seem to unlock the bootloader for some reason

I'm not an Android rooting noob (my rooting goes back to OG Moto Droid in late 2009) and I'm sure it's something ridiculously simple I'm missing but I can't get my bootloader to unlock. I've tried ADB/Fastboot, WUG's Nexus Root Toolkit, and Chevy's Android Job Box. Nothing works.
I got my 6P today, SIM'ed it up, booted up, logged in, enabled USB debugging, installed the drivers, and let it update. When I opened WUG's NRT, I saw that I had an Android build one step later than the NRT. Mine's MD80BL and K is the latest in the NRT. I thought that shouldn't be a problem and selected the "any build" option with the Nexus 6P. I went through the installing drivers process and can access the file structure of the phone through W10.
I then went to the unlock bootloader option, clicked through the prompts until the phone rebooted into the bootloader and clicked the OK button to unlock the bootloader. About two seconds later a window popped up on my desktop telling me my bootloader was unlocked, my data was wiped, and I would have to go through the setup process on the phone. Excellent, except my phone booted right back to my stock homepage. I tried again with the same result.
I then tried it manually using ADB/Fastboot. The "fastboot devices" showed a connected device which I assume is my 6P since I have nothing else Android connected. When I type in "fastboot flashing unlock" I get all the fastboot commands/options as if I typed an unknown command. "Fastboot oem unlock" didn't work either. I went and downloaded the latest SDK and retried everything with the same result.
Here's my Build Number.

Here's what I get when I try to use fastboot to unlock the bootloader.
Any help will be much appreciated. I expect I'm going to feel stupid when my mistake is pointed out but I'm here to learn.
Upgrade your adb/flashboot setup. Probably too old.
You must allow the option to unlock, then go to fastboot, the run the command, with an updated version of fastboot command.
Ah, I see. The SDK Manager is not installing into my SDK directory. I'll copy/paste, retry, and report back. Thank you!
Now I get this message that unlocking the bootloader isn't allowed.

Go to developer options & turn on the option that says enable bootloader unlock and retry.
Ha! I do feel stupid.
Thank you very much!!
You are very welcome!!!

ASUS ZE550KL - My phone is the god to failure =]

Hello everyone,
First of all, I apologize if this post is in the wrong section. Also I'd like to say how awesome it is everyone that is involved in these projects.
My Issue is I can't get ANYTHING to work, I have tried so many roms that apparently work for my phone and I always, foot errors, signature errors though the adb. I have tried every program to unlock bootloader but apparently does not work unless you are running V2 551 2.40.*.* so I went and downloaded this, and wants again can't flash the ROM. The unlock bootloader was weird, I went through all the installation and I don't even know if it worked to be honest. I can boot into the phone via power and volume down, and get a menu that includes, apply apps from ADB, wipe/restore phone, fastboot mode * which goes as far as my phone saying *FASTBOOT !!!* then thats it will not continue. The power and volume up does the same thing. So basically I'm starting to think this piece of crap phone will never have a decent operating system on it. The phone is in developer mode and USB debugging is on also. * Basically have done every single tutorial I can find and nothing works*. Also the twrp doesn't even work. I have even tried flashing back to an older version on the phone and get the same ADB errors. I have installed all the ADB and also minimal adb and fastboot and all drivers for the phone as well. * TRYING NOT TO MISS ANYTHING*
My phone specs:
Model: ASUS_z00LD
Android: 5.0.2
Baseband Version: 202c10_10.0.0_160120
Kernel: 3.10.49-gec27b65
Build: LRX22G.WW_user_1.17.40.1106_20160202044030520_2015052101030010000300001

Did you try to unlock bootloader the official way? I myself unlocked the ZE550kl following this thread http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263
You can check if bootloader is lock or not from fastboot by entering "adb>fastboot oem device-info" should show up somewhere between the lines "Device unlocked: true"
After unlock only then you can install Official recovery TWRP 3.0.0-0 from here http://forum.xda-developers.com/zen...recovery-twrp-3-0-0-0-touch-recovery-t3317513 .
If needed TWRP will also help you root your phone once is installed.
Good luck!

It is still locked or you don't the false, false, false? After oem info it said failed and then try flashing twrp makes no sense
Reflash stock fastboot rom with miflash or use a deep flash cable. And then unlock it correctly
If nothing works you have to open your device and use testpoint method.
really nothing works.
miFlash gives me an error in red.
I already tried with the flash cable qualcomm but the phone when it vibrates it displays the MI logo and is off.
I tried recovery twrp.img but still the same error message
Method MiFlash:
Rom FASTBOOT for Redmi 4 prime: markw_global_images_V8.5.4.0.MBEMIED_20170925.0000.00_6.0_global

Fastboot method won't work as your bootloader is locked. Try with deep flash cable or test point method.
Trying to flash twrp also not gonna work.

I tried the deep flash cable:
click on the + and - button of the volume
plug in the phone and click on the button of the deep flash cable until the phone vibrates ... except that ... when it vibrates it displays the MI logo and ends ... but it is visible on the manager peripheral
Don't use "wipe_all_except_storage".
Use wipe_all only.
