I have a Z5C(E5803) that was originally able to unlock the bootloader and let me flash ROMs, specifically the Cyanogen ROM that CTXz has been working on. I ran out of power and got stuck in some kind of nasty bootloop yesterday that prompted me to re-flash boot.img and TWRP.
After I did these things I left it charging for a few hours and it was able to boot into TWRP where I then restored it to a backup of the basic Xperia pre-loaded ROM.
This all worked fine, thought I could boot into TWRP and just flash the Cyanogen zip again. I can get into TWRP just fine but I attempt to flash Cyanogen I get an "ERROR 7"
I have since done several wipes, gotten into the bootloader settings by entering that code in the dialer and have seen that bootloader unlock = no. I distinctly remember bootloder unlocking being allowed the first time I installed CM on my device, what could have caused this?
I was able to use it with fastboot anyway and install CM13 again, maybe this was a bug?
When I tried using oem unlock command with fastboot it said my device was already rooted even though I had just restored from a backup, and then I just proceeded normally from there.
use CM13 official Recovery to FLASH CM13.
also i don't think so twrp3.0.2 is out there for z5c. are you using any other variants Twrp? (YUGA ? )
I have Redmi Note 3 SD. I applied for official unlock while phone was on MIUI stable 8.0.6.0 (Lollipop) , but I did not wait for permission and I unlocked unofficial and I upgraded to MIUI stable 8.1.1.0 (Marshmallow). Safe TWRP is installed and phone is rooted .
What to do now ? Should I continue with official unlock ? Could it be done if phone is already unlocked (unofficial) ?
Does it change anything significant ? I think I would prefer to be officially unlocked , so the bootloader doesn't ever lock again , but I am not sure if I can or if I should proceed from actual state .
Thanks
PS - Just checked Mi Unlock status in settings and it says - This device is locked !!! . But in Fastboot says bootloader unlock : true !!!
I'm in the same position, and I've sometimes considered unlocking officially. But, for the most part, I am happy with my unofficial unlock and worried that the official process will not work immediately, so I haven't bothered to officially unlock yet.
This would be the proper procedure for doing so, I believe.
1. Take a full backup in TWRP and be sure to copy it to a PC or somewhere separate from the phone. Also copy any important files from internal storage to a PC or some external storage.
2. Flash the latest China development rom using Miflash. (This would relock your phone).
3. Boot and log in with your Mi Account. Check in with "find my phone" to make sure Xiaomi knows you are logged in on your phone with your account.
4. Unlock via the official method using the Mi Unlock Tool... and pray that it doesn't get stuck at 50%. (If it does. Do "find my phone again" and try again later... and again later... etc. Sometimes it reportedly takes days. This is why I haven't bothered to do this yet.)
5. After officially unlocking, you could theoretically restore your TWRP backup (probably avoid restoring any weird partitions other than system and data in case it screws up your bootloader).

I followed this guide - https://www.youtube.com/watch?v=PtoeZg6K-z4&feature=youtu.be
Update - I tried unlocking official without flashing dev rom and relocking the phone - of course it didn't work because MiFlash could see the bootloader already unlocked . I will not bother anymore to unlock official if actual state of phone is safe for further custom roms .
Just to make sure - can someone advise if I can flash xiaomi.eu roms from Safe TWRP without worries ? Do I need to flash Universal boot img patcher too after I flash rom ?

I went through same path. Now on LAOS 14.1 . You can flash .. but do take backup of all partitions. Also do try to find what your FP sensor is. You may end up in issue like this https://forum.xda-developers.com/showthread.php?t=3543397
Scroll though my other posts for more info.
The problem with Settings crashing , I solved by flashing Radon kernel - also FP is working with this kernel .
It looks like this Redmi Note 3 is much more prone to brick than Redmi 3 I used before. I went through quite a few bricks and failed flashes while unlocking and upgrading to Marshmallow .
With Redmi 3 , which I bought unlocked from Greece , I never had a single problem flashing custom roms - never used fastboot, edl , myflash , just TWRP .
So - no need to flash universal boot img patcher or anything else after flashing custom rom ?

Most guides say that you need the latest dev rom in order to unlock.
If you want to try with merely re-locked bootloader on your current rom, I believe maybe you can re-lock in fastboot?
"fastboot oem lock"
?

I would like to know which Twrp to use , now I need to get back to Miui official global stable with custom recovery [ need OTA , Incremental updates ] & also if I flash radon kernel will I receive Incremental updates?
ZCX Twrp is recommended?

Hi,
My H9 is currently running Oreo (following OldDroid's great topic good ... And the device is rooted. As usua(!) on rooted device, Snapchat doesn't want to authenticate me.
As there's no official ROM stock img, what is the best way to enable snapchat (how can i unroot without reformating all my device ?)
Thanks

The unrooting method is described in part 3 of the same guide (flash ramdisk) just don't do the factory reset afterwards. I just don't know if it is mandatory to flash the stock recovery along with this method or if we can just stick to TWRP. Try and tell. Cheers.
Ok... i did the following cmd:
Code:
fastboot flash ramdisk RAMDISK.img
fastboot flash recovery_ramdisk RECOVERY_RAMDISK.img
then, i installed snapchat AND launched it (-->connection)
after, went back to
Code:
fastboot flash recovery_ramdisk twrp-3.1.1-oreo-stf.img
and installed SuperSU
..and everything is fine !!!
thanks !
You can also use SuHide from the same developer which works fine with Snapchat. https://forum.xda-developers.com/apps/supersu/suhide-lite-t3653855
Hello. I recently tried the Pixel Experience (to test the GCam) after unlocking the bootloader and rooting my phone with Magisk. Everything ok, if not for the fact that finding myself better with the MIUI I decided to format the smartphone and put the Xiaomi.eu ROM on it. Everything went well but when I went to see if the API2 were still enabled (besides finding them NOT enabled) I saw that the smartphone gave NOT ROOTED!
I tried to redo the usual procedure with MAGISK but always error:
"Unsupported / Uknown image format" at the time of Unpacking Boot Image
Why?
How can I re-root my device?
Thank you and sorry for my english....
Its probably rom issue. Reflash the rom with orange fox recovery and flash latest magisk 19.3.
hi there
i have unlocked bootloader and phone is rooted .
every time I try to update my rom , this errors happen.
I tried over Wifi and mobile networks !
You need to restore your boot partition before updating.
After the successful update and before rebooting, go to Magisk > Install > Install > Install to Inactive Slot.

You forgot to mention that you have TWRP installed and made unsuccessful attempts with SuperSU installation. I'm pretty sure that you allowed system modification (it asks for it during first start of TWRP). Reflash at least the latest stock fastboot boot and system images, and then install OTA. Or wait for new stock fastboot image and flash it then.
