Hi!
I have unlocked the bootloader of my Xperia M DUAL C2004.
Now I want to relock it. I have tried the flashtool method but it fails. Some loader.sin file missing error.
How to relock it?

Will flashing that relock my bootloader?

Hi All
When I bought my XM the fw version was .17.
Before unlock booltloader i was made a backup on TA partition.Then i was made ftf file with my stock firmware but yesterday i lost it
My Q is ,if i flash another firmware version .17 ,then can i restore the TA partition and relock BL again,or this can be make only for FW from who i'm bakced up TA partition?
I may be wrong, but you can relock your bootloader in any firmware, but if isn't the same version from when you did the backup then your phone will stuck in a bootloop after relocking, but if this happens, just use Sony Update Service to restore the correct firmware and get the phone working again after relocking...
Mhm only must be on stock kernel,thats right?No matter the fw version(.17 or .8)?

Hello all
I have a question regarding downgrade.
I have a g5 xt 1676 dual sim 16 gb, 3gb ram. Now i am running npps 25.137-72-4 version. As u all know.. getting firmware for full flash is a pain for moto g5. I got this phone in some old firmware, and got two ota updates since then .. and it became 25.137-72-4 version..
Now i want to reflash it to stock firmware. I already have an unlocked bootloader .
So my question is.. since i have unlocked bootloader.. can i downgrade?
I have this firmware - CEDRIC_NPP25.137-33_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC
As you see.. this is 25.137-33
This is the latest i could get. ( Please feel free to share any updated firmware if you have, a twrp backup of untouched stock firmware will also work)
I am concerned about bootloader brick ( if any of you run 25.137-33 firmware, can you please share a picture of booloader screen, so that i can check if its the same as 25.137-72-4.)
So my plan is..
Since i have unlocked bootloader,
1) i hope i can flash 25.137-33 ( dont know if it works since i have updated firmware already) .
2) relock bootloader while flashing
3) receive ota update to update the 25.137-33 to 25.137-72-4.
And stay happy with a locked bootloader with complete stock firmware.
I dont know if this plan works, but i hope i can flash the downgraded firmware since i have unlocked bootloader.
So my primay concern and doubts are..
1) can i downgrade if i have an unlocked bootloader
2) is the bootloader of 25.137-33 same as that of 25.137-72-4
Please help me to solve these.
Below is the bootloader screen of my current firmware. 25.137-72-4
Can any one please check if it matches with the firmware 25.137-33
Any help for anyone? Can i downgrade with An unlocked bootloader?
Hi, I have the XT1670 variant, 32gb single sim
Currently running NPP25.137-93 firmware (actually a debloated version of that firmware).
Here's the picture of my bootloader I think it's the same as yours, I'm not sure if you can downgrade the bootloader, I have flashed the NPL25.137-33 several times in my phone and it always gives me error in the two first flash commands, this being "flash partition got.bin and flash bootloader.img"
The phone still reboots and works as it should
So can you downgrade? Yes I have done it and never had a problem
Can you relock your bootloader? I'm not sure
And I'm not sure if bootloader brick is a thing either
I hope this helps
Sorry I cant upload the picture but my bootloader version is: B8.23 (sha-8fcce1f, 2017-08-04 11:32:36)

You mean 25.137-33 is the version you have with b8.23 bootloader? If so its same.. not downgrade. But i dont know why u get flashing error even using same boot loaded.
1) flash partion got.bin - its the file that is responsible for repartitioning the nand memory and allocate partion for system, user data, kernel , radio, and all others..
2) flash bootloader.img - of course its the bootloader.. but how can it be error when u are flashing the same bootloader again
Do u have an unlocked or locked bootloader?
Unlocked bootloader, I have the version 25.137-93 with b8.23 bootloader, before flashing that firmware I had the 25.137-33 one with the same bootloader, there's a thread in the Moto G5 plus forum explaining how you can relock your bootloader, apparently it can be done, you have to relock your bootloader first in order to flash the complete firmware and receive ota updates

Hi.. I am a noob but I am a pro in Mi4 ( cancro) but this time It has locked bootloader and I got unlocked img from zuk developer website is about 512 byte and two users comment in the bootloder unlocking and twrp recovery section they are facing issue and actually unlocked boot img file should have 1kb but I am confused and another q can I flash terble compatable twrp at once and regarding rom installation also which partition to be earsed ( efs) and which not to and baseband update section I got it and rom installation I got but after baseband update I have to restore Efs???
And what is the size of unlocked boot img you guys got
Which zui you do have? Probably nougat one, so ur baseband should be 1.70, if its then there is no need to flash baseband.
Don't know about size on unlock img but you should go ahead and see ifs its getting any error then share here.
Ok
One more thing baseband for oreo is needed
I want to flash aex oreo
And what is that efs

First flash official twrp then according to your need and read full post carefully of the rom you are going to install.
There are several twrp and vendor to factory and vice versa zips, some latest build of roms need these zips to be flashed first and some don't required treble twrp so first read instructions carefully,
Ya I did but I have misconception with baseband
Can you msg me in whtsapp 9853687062
Bro plz msg me

If your baseband is 1.70 you don't need to flash baseband
