Bricked After trying to relock bootloader - G4 Q&A, Help & Troubleshooting

Hi guys, I have a G4 with V30 porting rom based on nougat.
I wanted to restore to stock everything or at least remove the "unlocked bootloader" screen at the startup to sell the phone with a better rom.
I've found a YouTube video and following it I tried to relock bootloader and now I have the corrupted screen at start. I'm so stupid, I know... but can you please help me to restore everything?
I can go to bootloader and download mode also seems working fine, what can I do?
Thanks in advance

Not sure I follow. However you may want to try a tool called WugFresh Nexus Root Toolkit. The server is down at the moment. You may want to try to re-flashing 5.1, it has a normal mode and a soft-brick mode.

Ouch sorry to here this. If you find a resolve for this please post back would love to hear about it. Best of luck to you.
Hi all,
Same here, but my bootloader is unlocked. I'm not able to flash anything with the tool kits. It seems like it can't be recognized in fast boot mode. Any suggestion?
Thanks

When you have it cabled up to you PC via USB port, can you open Windows Explorer and view the file on your phone? If not you have a driver issue.
In developer options in the settings, did you check "Allow OEM unlocking" ? If you didn't, you will not be able to unlock.

Then, just flash the system images from Google and start over.

You do not need to unlock bootloader to flash stock images since that is what the tablet is originally designed to run. It's very simple to flash. Please try it.
I think it is not correct unfortunately fo me
Here:
https://developers.google.com/android/nexus/images
has written:
4.If necessary, unlock the device's bootloader by running: fastboot oem unlock
The target device will show you a confirmation screen. (This erases all data on the target device.)

My Nexus 7-13 since MM works only correctly on my Windows 8&10 computers directly after wiping cache partition first. Incuding working bootloader (fasboot) driver without exclamation mark.
But if still not working, I also added correct hardware id's of my N7-13 to the android_winusb.inf file of the Google USB Driver. Because Google forgot to add them themselves.
My adjusted driver with explaining texts. Check if your N7-13 has same hardware id's, because late manufacturwd N7-13 (with preloaded LP not JB) have other Emmc chip and perhaps also other hardware id's: https://drive.google.com/open?id=0B_LknrYiQE02c2NzbGludW9BdkE

Mi 5s firmware installed on Mi 5s PLUS hardware

Dear Developers,
I have quite outstanding problem, I think the only at the forum. I have purchased "Xiaomi Mi 5s Plus" 6/128Gb phone, but I have received "Mi 5s Plus" hardware with "Mi 5s" firmware installed (and fake chineese version in addition (Global Stable 8.0.10.0.0 MAGCNDH). Model number is shown like "Mi 5s", memory volume and CPU speed is as expected, but the battery shows 3100mAh instead of 3800mAh, and the most disappointing thing is that the camera is not working at all (when starting says "Camera Error: can't connect to camera. Try restarting your device" (of course, it doesn't help...). The Seller does not respond (purchased in China via AliExpress).
I think all the above mentioned issues are coming because the firmware does not correspond to the hardware.
So, finally after reading the local forums I have understood that I have to reinstall the firmware to official Global Stable version (8.0.1.0) or to chineese stable (???). There are 2 ways: unlocking the bootloader (it is locked unfortunately) and install via fastboot with MiFlash utility or with locked bootloader using the EDL mode using the same MiFlash. But there are a lot of cases on local forum (but nearly 2 month ago) that after reflash in EDL mode the device become a brick (boot-loop).
So, my questions are the following. What are your sugestions in which way to proceed faster and more safe? Which firmware is more safe to try first in my case: global or chineese? Because on local forum it is written that to use EDL mode I need official english-chineese version to be preinstalled. What do you think about it? For me is not fully clear what will happen in EDL mode? Will bootloader also be overwritten or not? If everything is overwritten then why there are so many bricks/bootloops happened after using this mode with fake chineese firmware?
I have already requested permission to unlock bootloader, but there is no respond from xiaomi since 3 days already... hopefully because of New Year holidays (but in China?... strange...).
Also I have prepared an engineering cable to have possibility to enter EDL mode in case of bricking/bootloop. But I need your suggestion how to get rid of possible problems in my special case.
Many thanks in advance!
Heya,
The easiest way would be to download the global ROM from http://en.miui.com/download-315.html and flash it in the phone settings (about phone, firmrware upgrade, menu, choose ROM). I had the exact same "fake" ROM and had no problems flashing the official one.
Cheers!
*Edit* also, if you use the the MIUI-suite program and download the "fastboot image", bootloader, recovery, system and sdcard will be wiped (just tried)... flashing from the phone settings chould wipe aswell but never checked.

I have already tried to flash via about the phone with downloaded ROMs (recovery image), it says "cannot verify the package" and does not proceed... Looks like because bootloader is locked.
Mi PC Suite program cannot connect to phone at all. Tried different version, also chineese one.
And I tried different ROMs (stable global, stable chineese) - no result...
You are able to flash an official ROM with locked bootloader so it seems your phone actually thinks it's a Mi 5s, wich complicates things. Could you try downloading a Mi 5s official ROM and see if it still complains about verification?
The chineese version of Mi PC suit should work with Mi 5s plus but you have to put phone in fastbootmode for it to connect, volume down + power when whone is off.
If your phone has the wrong bootloader you might have to wait for BL unlock to force flash your the Mi 5s plus ROM.... or just flash twrp and flash whatever ROM you want

Good idea about "Mi 5s" global stable, thanks, will be interesting to try (a little bit later).
And I didn't know that Mi PC Suite should be connected in fastboot - another thank you!
By the moment I've got the unlocking approval, so I'm going to proceed in a way with unlocking of bootloader as more safe way by my opinion.
Many thanks for your help!

Invalid boot state when trying to unlock oem

Hi guys,
I bought a Moto Z Play recently with the gearbest reduction. The software is locked in retcn so cannot be upgrade after 6.0.1
I would like to flash CM or stock rom, not decide yet.
But I have a problem now. I receive the message "Invalid boot state" (see screen). I verified if OEM is unlock in developer options and it is. So I don't understand why I can't unlock oem.
Have you got any idea ?
Thanks
Same problem here!

Possible to flash China MIUI on top of fake global ROM?

Edit:
9.6.6.0 is the official global ROM, so thread is irrelevant
Hey guys,
I just bought my Max 3 today, and sadly, I received it with the fake ROM - 9.6.6.0 "Global" (OEDMIFD).
I began unlocking my bootloader, but it says I should wait 720 hours...
Right now I just want to flash the legitimate, Chinese MIUI, preferably without waiting a month with a buggy, fake, dangerous ROM.
Can anyone 100% confirm whether it's possible and safe to upgrade from the fake ROM to the official Chinese ROM, with a locked bootloader? (using the recovery/updater methods)
I'd like to upgrade to V9.6.11.0.OEDCNFD.
Right now, when trying to check my anti-rollback status, I get "GetVar Variable Not found".
Help would be very appreciated.

I don't think you can flash the China Rom in recovery mode, if you don't flash the TWRP first. And to flash the TWRP you need to unlock the bootloader. But since you received the phone with the fake ROM, I wonder you have the locked bootloader...have you checked the first 4 seconds when the phone boots on, if you have the words "UNLOCKED" mentioned on the screen just before the logo and the words " ANDROID"? You should be the first having the fake rom and the locked b.l....

Thanks for responding!
If I recall correctly, the thing about MIUI ROMs is that they often can be flashed without TWRP, since they're MIUI. Some kind of internal Xiaomi thing that allows you to move between MIUI versions without unlocking your bootloader.
I, too, am very surprised. I suspect the store I bought from received the phones unlocked, and actually relocked them. I checked the moment I got the device, it says it's locked in the settings, in the bootloader and in MiFlash
I am getting my unit this week and I'm sure it's going to come with the fake global rom as well so this thread is pretty interesting.
Is there harm leaving the fake rom on there? I guess that's the part I dont understand yet.
I was kind of hoping to avoid the whole messing around with roms on the phone until that stuff becomes more solid.
