[Q] Question about lock 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)?

[Q] How to be sure that Bootloader is Unlocked, still receiving OTA updates

Hi I am a newbie. I had rooted my phone using Towel-root method and am even using xposed framework and am running stock version. After this to Unlock my Bootloader I fallowed procedures as given by sony, but after i entered unlock command in cmd, my xpeira m went into bootloop.
I tried repaing usning pc companion it said that my mobile has been modified and cant repair, and hence using flashtool flashed stock xperia m rom and had to root again.
But the problem is that I still receive OTA updates from Sony for Walkman and album apps. If my booloader is unlocked I shouldn't be recieving those right ? How can I confirm for sure without flashing anything ?
Another question: Now If i flash CWM from here http://forum.xda-developers.com/xpe...ery-philz-touch-6-41-6-xm-dual-t2795778/page2 will that erase my rom ? I mean do I have to flash my stock rom and reroot after flashing CWM for my device to work ?

i think i have an answer

Hi raghu,
see answer to ur first question, i dont think bootloader status will effect ur updates , because at first i tried to install CWM and went into bootloop , before that i unlocked my bootloader using flashtool, so i flashed .ftf file and went back to stock , when i tried to flash CWM i noticed that my bootloader was still unlocked , flashing .ftf didnt change it at all. i dont know whether this happened to me accidentally or it will really doesnt effect ur bootloader status but the answer is bootloader status will not effect ur updats ( as far as i knw).
answer to ur 2nd question is no it wont erase ( i am sure about it :good ur current ROM, if u flash it right. Dont worry i tried that recovery before, its gud and flash carefully, dont end up into bootloop once again ..safe flashing
thnx :good::good:

Your device's bootloader is absolutely locked if you are still receiving the OTA updates (and installing ). And I would suggest you to check the Bootloader status in Flashtool.
No flashing the CWM will not affect your current ROM

https://www.dropbox.com/s/ncyza0776myusll/Capture.PNG?dl=0
connect ur phone in flashmode and click on the BLU icon , then it will automatically get the code for ur IMEI and all u need to do is click Unlock and if u flash CWM on locked bootloader it wont work and u may end up in bootloop ( nt sure abt that coz never tried till nw )
hit thanks if this helps.:good::good::good:
hope this helps ,

As far as I am aware only the OTA firmware updates no longer work when you unlock your bootloader, the OTA application updates should work as intended.
For installing the kernel, all you have to do is put your device into fastboot mode, select the kernel with flashtool and then let flashtool work its magic. It won't wipe your ROM as it doesn't touch the /system partition.
You don't even need flashtool to check your bootloader unlock status either. Type in *#*#7378423#*#*, tap Service info, tap Configuration. You will see a section what says rooting status. Underneath rooting status you will find your bootloader status, it will read one of three things;
1) Bootloader unlock allowed: No (meaning you cannot unlock your bootloader, you shouldn't see this as you have unlocked yours by the sounds of the first post)
2) Bootloader unlock allowed: Yes (meaning you can unlock your bootloader, if it says this and you plan on unlocking the bootloader I hope you make backups of your TA partition cause you have no way of locking your bootloader again else. This goes for anybody reading this)
2) Bootloader unlock: Yes (meaning your bootloader is unlocked).

You need the original fw on an SD card and the stock bootloader. Boot into recovery and install the fw. There are several threads in the forum discussing the details.

Yes, it doesn't matter whether the BL is locked or unlocked, or whether your current fw is rooted or not.

I downloaded stock rom and copied to dload/update.app but all it gives me Error in recovery. Is there a way to flash stock software to this phone using a windows tool ? This is one of the most inconvient phones to flash.

Version latest stock rom

Does anyone have the latest retail version of the G5S rom stock?
Version latest is NPP26.102-49-1

this firmware will not come out, it will have to wait for the next one.

But mine version is on NPPS26.102-63-1
Will this version be released?
And if I try to flash .49 version will I get error?
Thanks a lot

I think I found one place where it's suposed to host the "MONTANA_NPP26.102-63_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip" file, but it's a paid download site.
i'm not going to pay to download because money in Brazil is something very scarce especially for something charged in dollar :silly:

So my guess is, we can still flash .49 version rom even we're on higher version. (just simply not to flash gpt.bin, this cause error when your version is newer than .49)
And after installed .49 version, we will receive OTA update then we update it?
Not sure if this is the correct way to get back to stock rom and relock the bootloader...

To relock the bootloader you'll need a firmware more recent than the previous one you installed. If you had the .49-1 installed, you'll may need to wait for one more recent firmware popout as this .49 will give errors while installing (the "oem lock begin" command only locks the bootloader if you install every single file from the firmware, which will fail because an lower version of the firmware was installed).
In short: you can get back to stock but can't relock bootloader unless you didn't installed the OTA .49-1 or have an more recent firmware available

Yes, you can update without worries. Just remember to maintain your system untouched before any update. If you root or install custom recovery, the update will fail and may get into a boot loop

So I'm currently running NPPS26.102-63-1 , and my bootloader is unlocked. Am I still capable for OTA update? And if I decided to install custom recovery and rom, can I flash .49 version stock rom?

You can upgrade through OTA with unlocked bootloader, you only can't if you modify your system. But if you are running .63-1 I'm not certain about reinstalling the .49 ROM as they may be different, like different modem or other resources like NFC resulting in bricking. Test at your own risk. I'd like to test .63 ROM, but I can't find any free places to download it.
(Or if you want you can also try the ZUI ROM, it's a stock rom from a chinese moto g5s with ZUI interface)

So the reason is the latest firmware for locking bootloader
Untill now I have thought that the problem is with only my device can we ask for Motorola for the latest firmware releases so that we can relock our bootloader

They used to have a site for you to download firmware, but it hasn't been updated like 3years... Even Moto support doesn't know where to get it..

I bricked my phone yesterday and flashed the stock recovery via the MIUI flashing tool. B4 I went to reinstall TWRP and Root the device again,q I checked the bootloader status and found it had been locked. I went to unlock via the unlock tool and surprising to say I didn't have to wait 3 days this time.
