Hey
the engineering bootloader has been leaked a while ago, and, from what I understand, it is based on 5.0.2
If you want to downgrade a 5.1.1 device, downgrades aren't possible due to restrictions in the new bootloader of 5.1.1.
Now, theoretically, is it possible to flash the engineering bootloader (to change the 5.1.1 bootloader) and after that flash a stock 5.0.2 rom with odin to downgrade?
The bootloader has been changed, so the restrictions should be gone, or am I missing something/misunderstood something?
Greetings from Austria!

I'm on stock JB and wondering if I should upgrade to kitkat.
I have a tripped knox so will have to odin to upgrade.
is there any advantage in having a KK BL over a JB BL?
I'm reading that android and samsung are getting too security minded,knox and bootloaders etc
I know you cannot downgrade once you've KK'd and there's something about a locked bootloader?
although I'm sure the clever peeps in xda have already found a way to unlock it.
all roms seem to be KK now and JB's are hard to find which also points to a reason to go KK
will I have a locked BL once I've updated to KK with odin?
So.... I got lollipop whithout rooting or changing anything (everything stock) but now i want to root my Phone and add a recovery, is it possible in android 5.0.2? Or i have to downgrade to kitkat?
i Think you schold Downgrade,other unloock Bootloader and Root directly
You can root without downgrading. But u have to have unlocked bootloader
Hi!
I've got a Xperia Miro (ST23i) which has Android 4.0.4 official firmware, 11.0.A.5.5. I now want to upgrade it to 4.1, mainly because of an app which I use now demands 4.1.
The phone is rooted but bootloader is locked. When checking the bootloader if it can be unlocked it says "No".
So my question is, can I upgrade it? Is there any stable 4.1 that I can install even though bootloader is locked?
I know there are roms based on stock kernel which can be installed and I assume those would work on a phone with unocked bootloader. But would it show as a 4.1 phone and the app I mentioned would work or would it be just the same as with the stock 4.0.4?
Thanks
This can't be a difficult question
Anyone knows and want to share their wisdom?
Edit:
Got my answer in another thread. Apparently it's not possible. Have to unlock bootloader for that.
I gather that it is necessary to unlock the bootloader in order to root - is this possible to do on the Verizon version? If so, could someone point me towards a tutorial, as I have only found posts on rooting, not unlocking the bootloader.
To date, it's not.
Thanks.
So then it is not possible to root the Verizon version?
[ASK] bootloader version
hai guys, need info of moto z xt1650-03.
i've moto z 7.1.1 and BL 91.08.
i've already tried to reflash with version 6, but i've got the error for downgrade issue.
so i flash it back to its original.
so much work to do this, coz i've been very hard bricked for downgrading it.
the question is, is it possible to downgrade BL 91.08 to other version ?
i think that if i can downgrade it, it can flash the old version like MM or N 7.0
many thanks.

I don't think bootloader can be downgraded on any devive beside nexus.
Hello!
I recently bought the 8" M5 without realising the hoops I'd have to jump through to unlock the bootloader.
After getting lucky and being able to downgrade to FW163 I have successfully unlocked the bootloader and I've been running a treble rom. Yesterday I wanted to try out an OpenKirin rom, so I flashed the stock EMUI 8 firmware in order to then flash the OpenKirin rom.
After flashing stock I realised my bootloader was relocked - not a big issue as I still had the unlock code and I was still on FW163.
My question is - if I upgrade to EMUI 9 ota will this relock my bootloader the same as manually flashing 163 did, and if so, will I still be able to unlock on higher FW versions since I already have the unlock code? As far as I'm aware the issue we were faced with was actually obtaining the unlock code after official support ended, so in theory now that I have the code I should be able to unlock on any firmware, right?
Thanks!

Theoritically said, yes, because the xloader have those kind of hexes that stay the same even after updating the firmware and the xloader and as additional info, I'm now on Omnirom for EMUI 9 vendor from Openkirin team and I can download the EMUI from eRecovery without getting my bootloader locked
