Hi there!
Today have flash into Pixel Experience ROM with TWRP.. to be honest I'm not satisfied at all with this ROM and there are some issues going arround.. I would like to return to the stock ROM (Android One) if its possible..
I've downloaded one ROM from http://c.mi.com/oc/miuidownload/detail?device=1900372 and maybe i can flash it with fastboot but if it not possible probably it will brick..
Its possible to return it to the original/stock ROM? How?..
Please, i will really appreciate your support.
Kind regards!

Sounds like you used "flash_all_lock.bat". Boot up the phone and enable OEM unlocking in developer settings and try to unlock the bootloader in fastboot again.

I think when flashing the rom you were in slot b and plus you have locked the bootloader. Now its not possible for you to flash or unlock bootloader, you have to go to service center. I have faced the same problem, and i took to service center and they fixed it. They told me that they had to take out the back panel.

Hi,
I upgraded to the Marshmallow rom via the OS upgrade early adopters at the weekend but now I am trying to unlock my bootloader to install CM13.
Unfortunately there is no option in the developer settings to 'enable oem unlock' and when I try to unlock i get:
Code:
sudo adb reboot bootloader
sudo fastboot oem unlock 1432461542335923
...
FAILED (status read failed (Value too large for defined data type))
finished. total time: 5.005s
After this no further fastboot commands work until I unplug and re-connect to the pc.
Is there anyway to enable the oem unlock setting via adb?
Or do I need to go back to a lolipop rom to unlock? If so can anyone tell me how to revert to a previous version.
Thanks.
I also upgraded to mm but the bootloader has been unlocked
because to not?
To answer my own problem/ for anyone else having problems it is necessary to remove the factory reset protection (frp) to do this you need to remove all pin/password/fingerprint locks, then remove all google accounts and finally do a factory reset.
Then the usual adb/fastboot commands work fine.
As linux33it says the bootloader can be unlocked without the option in the developer options.
I've a similar issue. I just updated my not unlocked KIW-L21 Stock-ROM from B140 to B330 via the early adopter option in the HiCare-App. Now I want to unlock the bootloader to install TWRP and CM13 afterwards, but I can't unlock the bootloader because FRP is locked and there is no "Allow OEM unlock" in the Dev-Options menu in B330.
Code:
$>adb devices
List of devices attached
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
W6HDUxxxxxxxxxxx device
$>adb reboot bootloader
$>fastboot oem unlock 48310xxxxxxxxxxx
...
FAILED (remote: Necessary to unlock FRP! Navigate to Settings > Developer op)
finished. total time: 0.011s
$>
Does anyone have an idea, what to do in this situation? Do we have to wait for the next official update and hope that the option in the Dev-Menu is available again?

Hi,

Yes under settings>accounts delete any google accounts but it won't hurt to remove any others as you have to do a factory reset (from the phone settings menu) anyway. I followed some instructions about removing frp online and it worked fine and allowed me to unlock the bootloader.

your lucky your phone boots at all ... The oeminfo is only for your phone it contains the serial number and iemi and now yours no longer match
I hope you made a backup of yours before you flashed someones else s .. only Honor can fix your phone now if you didn't

He tried to change his phone region by flashing oeminfo ...bad mistake his only hope is to restore his original oeminfo
The phone actually stores the iemi / build number info / serial num / etc in the efs1 - efs2 - and oeminfo along with local.prop and somewhere else on the phone that's not flashable without a jtag type device.
I have a backup I get from twrp efs and other thing bit how restor it

Hi,
i've a little (big?) problem with my xperia tablet z (wifi; pollux_windy). 2 years ago i've rooted the stock-rom (4.2 or 4.4) and installed dual-recovery. a while a did nothing with the tablet. later i installed cyanogenmod 11 using the installed recovery. someday in 2016 i updated to cyanogenmod 12, but i can remeber how i did this exactly - maybe with a update-app? after the update to cm 12 the dual-recovery was overwritten with a cyanogenmod-recovery.
i don't know whether the bootloader is unlocked. i've unlocked i to root the device for the first time. when i search for the imei in "about tablet / status / imei" there is only "unknown". so at the moment i can't unlock the bootloader again.
when i boot the device in fastboot mode and try to flash twrp with
fastboot flash recovery twrp.img
Click to expand...
Click to collapse
i get this error
fastboot flash recovery twrp.img
sending 'recovery' (10688 KB)...
OKAY [ 0.359s]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: 0.359s
Click to expand...
Click to collapse
maybe this is because the bootloader isn't unlocked anymore? how can i find out that? how can i unlock the bootloader again without the imei or how can i find out the imei?
a user in a german forum said i can use the sony tool emma, this should reset the tablet. but WHAT will emma reset? can i flash twrp after that? can i root it again?

From fastboot you have to type

as far as I have understood they are two different partition, Sony devices have the recovery in the boot partition whereas other phones, such as my OnePlus One, have a dedicated partition.
But what I'm sure is that when I flashed TWRP in my OPO I used the "fastboot flash recovery twrp.img" but in my pollux_windy I had to use "fastboot flash boot twrp.img"
doesn't work. i tried this on ubuntu 16.04 and in terminal i see the message
Code:
sending 'boot' (10688 KB)...
since 30 minutes. maybe this is because the bootloader isn't unlocked? but i'm not sure about that? how can i check this?
I remember very well the code I entered to get TWRP, now I'm also thinking you have somehow a locked bootloader...

if you use a stock ROM try: contacts/press three dots/Settings/press a place above home knob for few sec/it will appear Enter service Code/type *#*#7378423#*#*/Service info/Configuration
no, i dont use a stock, i use cyzanogenmod 12. i dont have the contacts app on mz tablet installed. i have tried to install google apps but the cyanogen recovery cant install the gapps. can i tried the service codes with an other app?

Try to download ExDialer - Dialer & Contacts and launch the code from there. I tried with it but it didn't work (probably because I'm on RR) so I doubt it will work for you but give it a try.
With the same app try
Code:
*#*#759#*#*
and I have "OEM mode = off" but I'm not sure if it means that your bootloader is unlocked.
Or download Secret codes, the app's icon is a magick stick with a star at the and it shows some codes and you can lauch them from the app itself. I think it only shows the codes available to your phone/tablet because it doesn't show 7378423.

On CM there is no service menu, so it won't work.
Unlocking is possible with Flashtool or fastboot commands.

Hi, I used fastboot to boot TWRP without flashing it (using fastboot boot twrp.img). Foolishly of me when exit TWRP I was asked to disabled Stock Recovery wich I swiped yes. Now my stock recovery is gone. How do I enable it via TWRP again without having to flash it? or what are my options? phone functionlity was not afected, just the stock recovery.
thanks.
imho you either use twrp OR stock recovery. so in my opinion youve done all right.
Download fastboot image.. extract boot.img from it. Boot in TWRP using fastboot .. then install->install image->boot.img(file you extracted)->flash->choose recovery, not boot when where to flash->done.
If it doesn't work then flash the whole fastboot image with mitool.

I ended up flashing the whole image beacuse it bricked when using the command "fastboot oem lock".
any idea why it bricked? i did flash a stock recovery before in order to lock it again.
After rooting it im interested in locking the bootloader again. Maybe I skipped a procedure in order to lock the bootloader again??
Right now im rooted, phone working, stock recovery (since I flashed a fastboot image with SP tools) and unlocked bootloader but I want to lock it without bricking it again.
thanks.

To lock bootloader again you must flash stock image via fastboot with "lock bootloader" bat file (it is in stock image flashtool zip). But why U need to lock bootloader? i dont see sense to do it.

Hi, thanks for the answer, I want to lock it because some features got disabled when unlocking the bootloader, like xiaomis "Find mi Device". I also read that having the bootloader unlocked may compromise your data security.

So you had TWRP and you locked your phone? Did you read the warning at the bottom of the post that you linked?
You may have to claim warranty and get a replacement for the phone.

The command "fastboot oem lock" (which you used) will lock the bootloader. The warning in the link in your first post says "Warning: Pls don't attempt to lock your bootloaders with TWRP or any custom recovery's installed. It might just result in an unrecovereable hard brick. Bootloaders should always be locked with stock recoveries."
Please learn more about flashing before attempting it.

Hi, I write again here, sorry. Can anyone help me with the block bootloader procedure? I want to try custom roms and unlock bootloader is simple, but if I want to restore the phone like new, like when you open the box, what do I have to do? Anyone can help me step by step? Thank you so much
I have the bootloader unlocked and Stock rom official, to take advantage of the warranty what is the procedure to relock the bootloader. I read in this thread to fastboot and run: fastboot flash lock
Has no contraindications?
can you also use mi flash tool and flash_all_lock.sh script?
Thanks
Switch to partition A, run flash_all.bat from the latest fastboot rom, start the phone. If it boots correctly, lock the bootloader with fastboot flashing lock command or run flash_all_lock.bat
Thanks.

If you were able to switch partitions, then you did not lock your bootloader.
Reflash full stock Android 10 ROM, it might solve your wifi issues.
