Hi, i have one question. My friend could sell to me his phone a22, but phone is locked by operator (soft lock, not IMEI) - cause he hasnt pay for phone his loan. I chceck, that imei is ok, not block. Could i flash oryginal stock firmware without unlock bootloader? I cant press OEM UNLOCK in dev options cause phone block after boot - > please pay your loan - it says...
it is worth to cheap buy? can i unlock it by flash not modified softare?
I think you can flash a stock firmware without unlock bootloader. Have bootloader unlocked it is for install modified software like it is Magisk or/and TWRP, or even for downgrade system Android version.

I have a Sony Xperia M Single SIM and I download a cyanogen custom ROM. The problem is I can't enter to the bootloader or the recovery mode to install the ROM. I did this process:
I shut-down the phone, then i get pressing and holding the power button until the phone get on, and i pressed quikcly the button volum up too. And the phone doesn't response, it take me to the "Enter your pin" normal mode.
One more thing:
the phone is blocked on Orange here in Spain, and i searched if does exist any method to unlock the bootloader or something like that, and I found in the sony website some procedures to know if your phone can get unlocked, and i entered the following number *#*#7378423#*#*, then to: Service info > Configuration > Rooting Status. And the Bootloader unlock says No!!!!
If any one can help me to install a custom ROM I'll appreciate that. I have no idea how I can do it, specially on Sony's phones, on Samsung's phone I didn't had any problem.
I'm sorry for my English is very bad
Your bootloader is locked (and it's not unlockable), so, no way of using custom ROMs in your phone ate the moment...

So why it is Locked. The is a several phones has it unlocked. Why the mine ???
Can you explain me why is locked and no unlocked?
You should unlock it manually check the forums to unlock the bootloader
Just to make clear, Xperia devices has two types of lock: SIM Lock and Bootloader Lock. The SIM Lock prevent you from using SIM cards from other carriers, and you can remove your SIM lock in any device by paying to your carrier or to a service center (in some countries the carrier removes the SIM lock for free in some cases).
Then comes the bootloader lock. With a locked bootloader, you can't boot in recovery mode because there isn't a recovery mode in stock ROM (trying to do so will just start the phone normally). You also can't flash custom recoveries or kernels (needed to use custom ROMs) with a locked bootloader. All Xperia devices comes with the bootloader locked from factory, but in most of them they're unlockable...
If you bought your Xperia device directly from a retail store, your bootloader is certainly unlockable and you can proceed with the method you tried (go to Sony website, input your IMEI, get your unlock code, etc.). If you bought your Xperia from a carrier (Orange, in your case) then your bootloader is very likely to be not unlockable, and that's your case, your bootloader isn't unlockable, as you already checked by going into Service Menu with *#*#7378423#*#*. If your bootloader isn't unlockable, you are out of luck, you can't do anything, there isn't any other method...
And further info if you get an unlockable Xperia device in future: by unlocking your bootloader, your warranty is void and your DRM keys get wiped, because of that, some proprietary Sony apps won't work anymore (Mobile BRAVIA Engine, TrackID, "Download Music Info", PlayStation Certified features,etc). So, if your bootloader is unlockable, you should to a TA backup before unlocking it, so, in future, if you want, you can relock your bootloader and get your DRM keys back, so the proprietary Sony apps works again...
Also, removing your SIM lock doesn't unlock your bootloader as well as unlocking your bootloader doesn't remove your SIM lock. They're two different things, completely independent of each other...

Read the OP, its bootloader can't be unlocked
Hi Everybody,
I have a Xperia M C1904 on JB 4.3 [15.4.A.1.9] on Vodafone Australia
My bootloader unlock status is no i was wondering if it is possible to
A) Unlock the bootloader
B) install Custom roms (KitKat Possibly?)
C) get some form of custom recovery whether it be TWRP or CWM etc.
and also i would like to know step by step how to check whether the sim is locked and if possible how to unlock for free (if locked)
i know its alot to ask
Thanks
Andrew
I'll tell you everything I know.
Unlocking the bootloader unlocks the full capacity of the phone. This means you will be able to flash a custom recovery, and within the custom recovery, you can flash ROMs and everything else. But if "Bootloader unlock allowed" says no, then you won't be able to unlock your bootloader, thus not being able to flash a custom recovery. The only way to flash these is to implement a custom recovery for locked bootloaders, which is not yet available for Xperia M.
To determine whether your SIM is locked, the phone won't read it and would request for a SIM Unlock PIN.

A) we will never be able to unlock the bootloader if it says bootloader unlock Allowed: no.
B) possibly in the near future, if we get a custom recovery working on LB
C) some devs are working on it, but nothing yet. We could be getting it in the near future.
To see if your phone is sim locked, go to the phone app and enter the code *#*#7378423#*#* and a service menu should open up. Click on service info, then sim lock. If you have a 3 beside network then you are sim locked. If you have a 0 then you are sim unlocked.
Hello guys, sorry because may be this is the 50th time someone ask this question but the situation change every day. Yesterday I won from lottery and decide to go from G3 to G4. My model is European H815, I want to ask you can I root G4, change the recovery and e.t.c. without unlocking the bootloader? And also if I unlocked it is their any way to locked it again or to use my warranty? Thank you!!
well you can only root using low effort root(google it or find it here ) But to change recovery you have to unlock bootloader
No there is no way confirmed to relock your bootloader
GOOD LUCK
Thank you! If I root by this way and download Flashify and try to change recover what will happen ? Thank you!
without bootloader unlocked nothing will chnage ( recovery wont be installed ) and when you reboot your phone it will get u error (authentication error #9) as i remember and you will have to flash new firmware using lg flash tool 2014 so i dont recommend you do so
if u wanna change recovery unlock ur bootloader
you are welcome anytime
I did not get it, I hope you can light me up:
1. Doing root using low effort root means rooting without unlocking bootloader? (because I flew over the thread and did not read anything about it)
2. If I do unlock Marshmallow's bootloader, what happens when I downgrade to Lollipop via flashing proper KDZ? (I would guess that the unlocked bootlader will be overwritten!? So flashing Marshmallow again would end up in a locked bootloader, doesn't it?)
thanks
You can root lollipop without unlocking bootloader but with marshmalow you can't, you have to unlock the bootloader.
You need an unlocked bootloader for custom recovery.
Bootloader unlocking is a one way operation , you can't go back.
i bought a p2c72 version.... but it arrived flashed with p2a42 version, marshmallow and it does not find any OTA.
i think it is a fake/bad rom from banggood.
i wanna start modding but i don't know how to understand if my bootloader is unlocked. Could it be already unlocked... being already flashed with p2a42 rom ...... on p2c72 hardware?
No, you can flash an international stock rom over chinese rom without unlocking your bootloader.. You cannot find any update because the lenovo servers are down. If you want to check whther your bootloader is locked or unlocked then switch off your phone and switch on your phone, if an open lock sign appears on the boot screen then your phone is unlocked, and if you cant see a lock on the boot screen then it is locked
i checked into the OEM unlocking option inside the developer options...... i have a locked bootloader, i am waiting 14 days to unlock....
Simple question but can't really find the answer online.
Bought an H815, no carrier label etc. My ATT sim works in it.
I want to unlock the bootloader (OEM process) root, add TWRP and flash custom ROMS. Will this affect the factory unlocked carrier status?
How is it carrier unlocked btw , at the hardware level or bios type process? I see the H815 comes factory carrier unlocked?
tia
Assuming your phone was purchased sim free, then no, bootloader unlock shouldn't affect it. You can always make a backup with SALT first (bootloader can be locked when you take the backup) so if for whatever reason it does get removed then you can restore it.
Btw, LG's don't support fastboot oem unlock. You need to do it via Official LG bootloader unlock website or UsU (look here in the threads) if your device isn't supported officially - if it is an EU H815 it official should work though.
fr eBay sim free. I'll look into the SALT backup.
I did a bit of work already and signed up as an LG dev and do see the LG website process which I was going to do to start.
So then adding TWRP and a custom rom will not affected the carrier unlock as well?
thanks
