Can't unlock bootloader (iOcean X8 Mini) - Android Q&A, Help & Troubleshooting

Hello,
A friend of my asked me to install a new version on his iOcean X8 Mini.
After a few minutes into the process, I discovered that I couldn't modify anything at all.
Problems start occuring when I enter Fastboot via ADB (I power up the phone, connect it to PC, give it permission to use Android USB Debugging, then via 'adb rebeoot fastboot' I enter the Fastboot menu). Every command I enter here returns 3 dots just doing nothing. My command prompt is unusable after entering a command (for example 'fastboot oem unlock').
I've tried to push a ROM via ADB but this isn't working as well since it returns something like 'no permission' when trying to install, but I figured this was due to the locked bootloader.
Searched all over the internet for solutions, but so far nothing has really worked. What I somehow did mange to do is root the device (don't know if it was by default, I assume not), via RootGenius.
Anybody got any experience with this, and perhaps know some steps I can undertake to indeed unlock the bootloader of this phone?
Thanks in advance!

[Question] ZTE Majesty Pro

Hello,
I have a Straight Talk ZTE Majesty Pro LTE [Z799VL]. It runs Android 6.0.1. This phone occasionally installs apps and has an annoying app called AppFinder. I have tried to root this phone with KingoRoot and KingRoot. So, I need help figuring out if this thing is even rootable. I would get a more accessible phone, but I'm short on money. I know this is short on information, but I'd be willing to help in any way I can.
Any help would be greatly appreciated.
Boop.
I'm fairly certain this phone was released recently. Maybe it's just too soon.

The OP is running Android 6 but I have the Straight Talk boxed ZTE Majesty Pro and it runs 7.1.1 out of the box.
There is a thread called Universal Method with a file and instructions but my Android device is the only PC I own so I haven't given it a try. The post has a Windows and a Linux method.

Have you unlocked the bootloader?
I recently upgraded to an Android 7.1.1 ZTE Majesty™ Pro Plus LTE (Z899VL) from TracFone,, and was rather dismayed to find out that it has an unremovable Facebook app (among other rubbish that I don't want/don't use).
I've never rooted a device before, and I know that this thread's a little old, but would anyone be willing to post a very-newbie-friendly step-by-step tutorial/walkthrough for rooting this phone (assuming it's possible)?
I have Developer Options enabled, and I can easily unlock the bootloader if that's required. I just want to get rid of these useless (for me) System Apps.
Oh, also: I don't have Linux, so… if it's possible, perhaps the rooting method could work using a Windows 7 PC?
need fastboot to unlock the bootloader. to the best of my knowledge, which aint much. but i can not find access to any kind of dl mode let alone fastboot.

Well, I finally managed to get my 899VL (it's not a 799VL as I'd thought — sorry) to show up as an ADB device; it accepts commands from the ADB program… except that when I execute "adb reboot bootloader", it just reboots my phone.
The ZTE logo shows, then the TracFone logo, and then Android boots as normal. It's as though I simply used the "Restart" option on my phone itself.
Due to this, I can't use "fastboot" commands, because it doesn't seem to enter Fastboot at all.
I do have both the OEM unlocking and USB debugging options turned ON. My only guess as to what's going wrong is that it's TracFone's fault. (Alas, I have no proof…)
Is there anything else that I can do to try and unlock the bootloader? Or is this phone a lost cause?

Well, I don't know about any other method to unlock boot loader.
BTW, in case of some phones, turning on the "OEM Unlock" button in Developer Options unlocks the bootloader automatically, so maybe, just check whether your bootloader is locked or not.
Both Didn't work

I tried using both the wasy for the first one the device not going to fastboot mode it just restarts for "adb reboot bootloader".
i tried KingoRoot, Dr Fone but it didn't work.
Did you unlock the ZTE Majesty Pro Z799VL with this method???

Need some help with an RK3168 tablet, bootloader and write permissions

Hello!
I cant get further on with an my tablet an RK3168 device.All the specs are in this topic, because i was looking for a rom:
http://www.arctablet.com/blog/forum...ssible-clean-4-2-2-or-a-customcwm-rom/#p60994
But i ran into things what i can not really understand or place, and i also already tried a lot already..Maybe its the soc itself, hope someone can help me a little bit.
I wane install a rom, so i first made an backup with RK1.2tools and this backup is ready in flashtools1.37 from finless.It finds rk loader and its ready to flash..
But here i get stucked, adb works, minimal adb &fastboot , google usb driver, with usb debugging on..Adb works, but for example fastboot reboot-bootloader..Only switches off the device, it doesn't boot up in any mode...Tried button combinations but only recovery can show up.So no commands work for fastboot plus starting fastboot with keys, looks impossible.Also in recovery there is no fastboot.In adb i can see all the commands, but everything what starts with fastboot, will give me only an waiting for device output..Also adb shell gives me root, rooted with kingroot..But same thing, goes off and no fastboot..And yes adb has permissions from kingroot.
Because adb works, i can not believe that fastboot would not work, i think myself its the tablet who first has to boot into it before a driver will work.But fastboot oem unlock or fastboot flashing unlock bootloader all are not working.But why it even doesn't start in any fastboot from command pff i cant understand that..
On the internet i see that even fastboot has an screen..Could it be locked or so?
Only weird thing besides that is this! If i put it off, plug in usb cable and charger!!Press vol up or power, battery shows up loading..And i see rockusb device in device manager win7.I can install adb or fastboot on top off rockusb device.But adb shows no server running.And adb devices gives this: 1234567890ABCDEF Device....Thinks its no fastboot but very weird.It only works this way when charger is inserted and battery is loading..
Besides that, rooting was also a pain ...Tried rk188 solution for rk3168, but double zero after 3 times booting..Looks rooted, but Su is not there and cant get installed.It always ends like that, with or without kingroot.And other ways the same, with emulator pushing su and removing kingroot..Doesn't allow Su to be installed properly.
Nothing looks logical for me at the moment. No fastboot, but seems flash ready in RK1.37 tools.Is there a way around fastboot to find out first if my loader is unlocked.
I don't wane brick it with an locked loader, so how to get further on from here or are these soc different from others?
Thanks for any help!:good:

No Rooting software is working!

Hi everyone, I have a Samsung S6 from verizon (SM-G920V). My build number is NRD90M.G920VVRS4DRA1. Last updated Jan 2018. I accidently deleted some pictures through MyFiles and am trying to get them back. I have researched quite a bit and have found that all of the data recovery software available require my phone to be rooted to actually find anything. I am not opposed to rooting, but I am new to this. I tried lots of different "one-click" root programs, and nothing has worked. They all either freeze or tell me they aren't compatible with my phone. I either need a quick/temporary root that will work with my phone, or REALLY SIMPLE instructions to do it manually. I have a windows and a mac computer. PLEASE HELP. Thank you!!

cant get into bootloader!!

Hey all i dont know what the deal is but ive got an lg g5 that just will not boot to the bootloader. I've tried factory resetting it and all the methods to get to bootloader just reboots the phone fully. Adb reboot booloader, key combos, nothing seems to work. Any ideas??
First, connect your smartphone with your PC; plug in the USB cord in order to establish the connection.
On your computer access the Android SDK folder.
From there open a command prompt window: press and hold the Shift keyboard key while right clicking on any blank space.
Next, in the cmd window type “adb reboot bootloader” and wait while the bootloader mode is displayed on your smartphone
That's basically what I did and worked first time..make sure the adb and fastboot package is installed and open the command window from that folder

Did all that.. I mean I've flashed custom recoveries and roms to other phones before and never really had a problem i couldn't google..this has me stumped. It simply refuses to even access the bootloader.
If it helps it was a koodo phone and is running the latest official patch from lg on nougat. The only thing i could find online was that sprint supposedly removed all access to the bootloader on theirs, but i cant find any real info on that either. It reboots when i send the adb reboot bootloader but its like fastboot just isn't there..?? It reboots right back to the android home screen. Ive tried all possible key combos as well... Ugh
Which model is it..mines the h850
Ive got the h831
I think I've sort of answered my own question. From browsing the forums it appears the Canadian variant has the bootloader locked down and inaccessible, which would explain a lot..lol.. I really hate when this kind of thing is done to the consumer...ugh. Back to xiaomi i guess lol

Interesting - my xianomi hat an locked bootloader and i had to ask for permission (for the phone I bought!) to unlock the bootloader.
LG is also locked, but the unlocking procedure is way easier.

[Help] ZTE Avid 557 (7.1.1) Root?

Hi everyone,
I've searched a lot, but haven't found anything. I'm afraid my phone can't be rooted by Magisk because the bootloader is locked. Hopefully someone will tell me I'm wrong?
I followed a fastboot guide (enable OEM unlock, USB debug) and was attempting the command prompts via ADB fastboot folder.
"adb devices" shows me my device ID, however the next step - "adb reboot bootloader" - just reboots. And the following step ("fastboot devices") yields nothing.
From what I can tell, my phone has a locked bootloader and there's no way to unlock it. This is why the ADB fastboot command doesn't work for me.
Furthermore, there's no way to install Magisk without this function. I read something about downloading the original firmware for my phone, but I haven't found the firmware anywhere online.
Appreciate any help you guys can offer. Thank you!
Eric
Bump - please anyone / any ideas?
