(oem: unlock is not allowed), can't turn on oem unlock because factory reset bricked - Lenovo Vibe K5 Questions & Answers

[SOLVED] i'm stuck in a vicious loop of flashing that i need to unlock my bootloader to flash stock rom but my phone is stuck on the page "CHECKING CONNECTION THIS MAY TAKE A WHILE" hence rendering me helpless on how to turn allow oem unlock on in dev settings on my lenovo vibe k5, I used king root to root my device but it started misbehaving with google play services so i decided to factory reset it, now i can't even get into my phone, and can't even flash stock rom any suggestions how to get out of this?
Edit: HI everyone thanks for the helpful comments after I've SOLVED this just a suggestion for whoever who stumbles on this or is in a similar situation like this , Turns out my twrp did not do the factory reset properly and hence allow oem unlock was on and hence i was able to flash a stock ROM using QFIL program in QPST description of the procedure will be and can be found on the super thread of the device please refer and flash it.
IMPORTANT: flash a stock ROM of a lower version that seems to work wonders ,I literally had to uninstall android by wiping my system folder because I didn't have a backup[NOOB MISTAKE] and i thought i'll wipe entirely and reinstall the OS and that worked out by the power of other helpful XDA threads

One question
What is bootloader status when you buy the phone from your provider??
I want to buy it but Not if at the end i will have bootloader locked and not to be able to unlock it??
Like the Sony Xperia models
All provider ones comes with bootloader locked forever so you never even get root or twrp or anything custom
Please advice me regarding bootloader locked status
Thanks

[Q] Install Custom ROM in my Xperia Ray

I am not sure if I have a bricked phone, but I feel it's a phone without an OS.
I was trying to root the phone and get a Custom ROM installed. As I was reading through several forums, I found few rooting softwares and steps. I did all those, but seemed like the phone was not getting rooted. Then I read that I need to have an Unlocked Bootloader. I went to the Sony Site and got the Unlocking code. But what I did was I unlocked it after I had tried the other steps of rooting. It doesn't seem to have any recovery stuff installed as I am not able to boot in recovery. When it starts, the SONY display will come and a blank screen then again the same stuff repeats as if it is trying to start but cannot find an OS to boot into.
I know that I should have done the Unlocking first and then the root installation and stuff, but now I want to know if I can get an OS installed in this. Now I am not able to install the stock ROM using Sony Update Service as it shows the message: "The Phone contains modified software that cannot be updated".
Can someone help me out here with installing a custom ROM.
Thanks,
Vineeth

Help with rooting - custom roms install

I need help. I want to root my Moto E 2nd Generation (LTE MODEL) XT1524. I tried to root my phone with Kingroot, which I had rooted some other devices successfully. But it didn't worked on this phone which was soft bricked for a month (until it was fixed). I want to find 1) How to root the phone without computer (if it's possible), 2) How to fix it (There is a program that fixes the firmware of the phone, but I don't know how to download it) and 3) how to install a custom rom with flashing a custom recovery and all that stuff. (On this phone it is quite easy to unlock the bootloader. You have to go to developer options and tap the OEM unlock. Probably is a feature of Android 6.0)
If someone can help me with all that stuff, I would thank him/her a lot!
By the way, sorry for bad English...

3) You cannot flash a custom ROM or recovery without unlocking the bootloader. This all has to be done via a PC. You can follow these steps
forum.xda-developers.com/moto-e-2015/general/guide-unlock-bootloader-moto-e-2015-t3045748
The unlock bootloader in the option does not unlock the bootloader but just allows you to unlock it. If it is turned off and you try to unlock it, you cannot.
If it helps please hit the thanks.

unlock bootloader on vzw samsung galaxy note 2 with OTA 4.4.2/i605VRUFND7 ?

hi all, i have been ready through posts but dont have the answer, can some please help.
is it possible to install a custom firmware from this phone's current state. (bootleader never been unlocked)
and has ota 4.4.2 on samsung vzw note 2
many the instructions for install custom firmware say to get twrp installed, and this is where in stuck
i tried to install most recent twrp tar twrp-2.8.7.0-t0ltevzw.img.tar using odin and it seems to get about 80% but then fails.
i then tried to unlock bootloader so i could use fastboot to install an img file, like twrp-3.0.2-0-t0ltevzw.img but the "adb reboot bootloader" command just restarts the phone, skipping the fastboot screen
am i spending counless hours in something that is not possible?
I certainly have learned alot in my journey, but I'm getting doubtful its possible.
thanks all
i found this user trying to accomplish same thing, should have piggy backed off his thread, but as of 05/2015, still no way to unlock bootloader

Unfortunately the device has kinda been left behind those who have a locked bootloader really only have 2 options stay on stock with root. Or install safe-strap and flash a touchwiz 4.4.2 modified rom. Which is awful because this device has potential. If a developer is reading this please make one more attempt to unlock this device . I'm sure the xda community would help you. I definitely would! I hope a developers reading thanks very much..

Bricked my device, wanna help me out?

Issue status: Fixed
Issue details: Bricked device with Bootloader locked.
Issue solution : This thread
Thanks to: devcon69
Special Thanks for information: takagen, lindvall, cebu, darkhelmetnl
File sources: https://forum.xda-developers.com/redmi-note-5-pro/how-to/fix-arb-bricked-device-qfil-t3841780
Info sources: https://forum.xda-developers.com/showpost.php?p=79083641&postcount=38
Been flashing roms, wanted to try them out, and before you ask, yes I wipe cache, system, and data before I do a wipe...
But somewhere down the line, rotation stops working, I don't know why, but it just did and wouldnt work in any rom I tried
Eventually Twrp stopped letting me flash new roms giving me excuses like zip verification failure.
Then it stopped letting me flash other zips like verity disable and gapps.
Being basically locked to Havoc wasn't really an option for me so I decided to go the nuclear route and reflash stock rom+recovery which bricked my device but not before wiping my recovery and locking that pesky bootloader. "SYSTEM DESTROYED"
So here I am with a locked bootloader, only access to Fastboot, and what I believe is EDL as it shows up as Qualcomm driver in device manager if I do it right.
I tried using the same flash tool that bricked my device both in Fastboot and EDL, in Fastboot it tells me my device is locked
In EDL it tells me the device is locked and error getting "hello packet"
And when I try to use the unlock tool, it tells me my current account is not bound to the device, even though it used to be. And I don't have a system to go in to make it so again.
So does anyone know how to flash anything around the locked bootloader?
Hi
I do not have much knowledge of xiaomi, just my mi pad 4 ... But from what I read, you must never relock a bootlader already unlock with fastboot ... It almost systematically causes a hard brick
Try the steps did here ?

Doesn't really mention that in the instruction manual. And the flashing tool locks the bootloader anyway and the guides don't mention the bricking issue + anyone that suggests using the flash tool tend to leave that part out, it's only until after I done it and am googling how to undo are people showing up with comments saying "yeah you shouldn't have done that"
Like where were the warnings before?!

Hopefully ill have time to try that tomorrow but thank you so much for a suggestion.
I have put my device in EDL I think, kind of hard to tell with the screen off, but when I attempted the flash, the miflash tool told me sry can't do it cause of a lock.
I'll investigate later if it's anything different than what I tried before.
I definitely want to get it back to working order because I have yet actually got a chance to enjoy using it. The first thing I did was try to flash a rom and it's been downhill of trying to troubleshoot onething after another.
I didn't backup via twrp because I forgot, and I didn't anticipate just how locked down and a pain in the ass Xiaomi devices could be, and in the past on other devices, recovering from a bricked state is usually a more simple process.
Thank god my pocophone has a full miui backup via twrp
My device was bricked and the people credited helped me recover it.
Had to take off the back to put the device into EDL mode.
Used specifically the software /files and instructions provided by devcon69, the patches elf file was key
And the information provided by Lind all helped me more than I thought, particularly the part where he/she said "I waited too long"
So as soon as I opened up miflash tool, I clicked flash as fast as I could, maybe the tool goes through some sort of background security check and clicking flash starts before it finishes (I doubt it) , I don't know...

.HELP! ..SOS..!! Can't Flash TWRP, Magisk won't install zips.......

Hello! I can't seem to make TWRP Official app (from Google Playstore) and Magisk root to work.... so hacking game is still a distant possibility here. I downloaded both app, but couldn't get them to work, so now uninstalled both.
My phone is: Moto G7-Power with Android 9 (Pie), my questions are:
1. Which of these two should I install first on android without PC? Magisk or TWRP? Seem to get conflicting instruction from those tutorials on Youtube.
2. After downloaded "TWRP Official app" from Google Playstore, chose my phone from the list and downloaded the version for my phone. It said downloaded successful, but I can't flash TWRP, can't open it in recovery mode (hardreset), it wouldn't do anything!
3. As for Magisk apk... one of the two files won't install, the zip files.... it said "failed"... so what do I do then?
Can anyone please help me fix all these problems? Very frustrating right now.

Hello, Morky.
I am afraid I don't understand what you really mean by your question above. You have not used a PC yet but tried to flash TWRP. Please give me more insight on what you are trying to do.

Thank you, Kumar for your response. First of, I'm NOT a techie like you. I just followed these tutorials on YouTube....
With TWRP app this is what happened (or not happened):
https://www.youtube.com/watch?v=RtvI2C9VrOY
Started having problem at the 3:00 min mark here as well... even with hardreset
https://www.youtube.com/watch?v=wEHChHcpZEI
I couldn't do what this guy did at the 3:00 min mark....
With Magisk Manager app.... what happened was just like at the 3:00 min mark on this video
https://www.youtube.com/watch?v=DvlLy42UtGg
I thought explaining what'd happened by referencing what I was doing per these tutorials would better answer your questions, since I don't know how else to say it, again not a techie person.

You have to unlock your bootloader first. It requires that you read out a encrypted code from the phone, via the USB port using ADB/Fastboot. The code is entered into a web page at Motorola, and if your phone can be unlocked, they will send you a unlock code. Then you fastboot the unlock code. then fastboot twrp. then flash magisk.
you may consider going to the forum page for your phone, it will have all the details.
https://forum.xda-developers.com/g7-power
look under the guides section
hope that helps

Hello, Morky.
I do not understand how one can flash any image directly from the device without rooting it. Now, in order to root your device you will need either TWRP or flash SUPERSU or Magisk using fastboot. If you wish to root your device and install TWRP on it, you will require access to a computer.
The phone has to be BOOTLOADER unlocked in order to install TWRP and Magisk. Turning on OEM unlock, is a step in unlocking the phone - but it does not unlock the bootloader.
When you are saying the phone is unlocked, I believe you mean the phone is unlocked so it will run on any cell phone carrier - a way the phone is sold. But its not bootloader unlocked.
Bootloader unlocked is different - Most phones are sold with the bootloader locked and because of that, you cannot modify the operating system. Unlocking the bootloader allows you to modify the the android operating system.
You will have to install Motorola USB drivers on your computer. Go to the Motorola page at: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a and read about unlocking the bootloader. You will have to create a Motorola account to get an unlock code, if the bootloader can be unlocked. The pages will also have a link to obtain the Motorola USB drivers (MotorolaDeviceManager_2.5.4.exe).
You will need to install Minimal ADB Fastboot, a terminal program that allows you to push data/commands back and forth between the computer and your phone via the USB port. https://forum.xda-developers.com/showthread.php?t=2317790 You will use the FASTBOOT command to obtain the encrypted unlock code from the phone. You will also use FASTBOOT to install the unlock code that Motorola will send you,
After the bootloader is unlocked, you will use FASTBOOT to install TWRP into your phones recovery partition. TWRP info at https://www.xda-developers.com/how-to-install-twrp/ TWRP is a backup and recovery program that is used to install programs, etc,
After you install TWRP, you can install MAGISK, which will ROOT the phone. Magisk info at https://forum.xda-developers.com/apps/magisk.
Please go to the forum I told you about and under the guides section you will find documentation that explains how to root the phone and install custom ROMs.
https://forum.xda-developers.com/g7-power A guide will give you the finer details for your phone model.
Before you do any of the above, I advise you strongly to have a backup. Using FASTBOOT there is a command called "getvar all", it will return a long printout of info and it will include a readout of the original firmware installed on the phone. You will want to know this in case you brick the phone. Having this info will allow you to obtain the original firmware and be able to restore it via FASTBOOT. Firmwares at https://mirrors.lolinet.com/firmware/moto/ .l After installing TWRP, you should backup the phone to your SD card and then move the backup to your computer for future needs.
Good luck.

Deae Nivead,
..Oy! That sounds painful!! Guess, I have no business be doing this lock/unlock/rooting thing, huh?! Not a techie at all, this is very foreign to me! And those guys on YouTube... they lied then, said I could do all these without PC... Yeah, right! Turned out, it wasn't as easy as they were showing on videos. (((sigh))) Would be easier if I just send my phone to you?!?!!!
Thank yoooouuu soooo much for taking the time to write/tell me all this, truly appreciate your help and replies.

Kumar,
I guess those YouTube tutorials omitted left out a lot of steps and not as easy nor simple as they made it to be.... "without PC" as they claimed. How would someone with no background in computer programing, nor a "techie" like you here at xda... like me would know that?! If you "don't understand how....." I wouldn't understand either!! More so than you. One thing I've learnt now, all those tutorials about rooting and TWRP. on YouTube... are crap.
