I've had trouble getting bluetooth to work since flashing to DCD. I haven't had any trouble with anything else. I've got the new Verizon MR1 update installed and everything is stock other than the boot loader which is the No2Chem 2.47 loader. Aside from the possibility that it's the reason my BT doesn't work, I guess I need to send the phone for repair. Either way, I should get a stock loader in there. Anyone have any suggestions for a stock loader? Did the MR1 need anything other than the original loader? In other words, if I put the old loader in there, will I have a problem booting? Any suggestions will be appreciated.
Thanks
Is there a option to run CWM with goobstopper without a unlocked boot loader. I tried the bell 2.3 update but keep getting a error about a default application that was removed and then reinstalled. The phone is still under warranty and I don't want to unlock the boot loader if I don't have to. If anyone else knows a way for me to fix the error with the app that would be great as well.
Thanks,
There is the bootstrap recovery but I don't believe that will work for what you want to do
The short answer for your question is no

I was wondering what would happen if someone installed an alternative rom and then relocked their bootloader.
What problems might this cause, if any?
no problems but they would be stuck on the rom until they unlocked or ran an RUU i believe
I'm really out of ideas to what's causing this so I could use some help.
My tablet has been fine for a long time and has had many roms on it previously. I have been on rooted stock however for over a year now and decided to try a rom again....
However I have tried 3 different roms now all with catastrophic problems. I install them fine through twrp along with gapps then reset Tablet but get a black screen with just a blinking charge light if it's plugged in. No boot logo or anything.
I managed to revert back to stock about 5 times today through flash mode and flash tool but I don't know what's going on.
I rooted, turned on debugging and reflashed twrp but it keeps happening across different android versions too. I thought maybe I had relocked bootloader so I tried to check through adb oem but it freezes, so I ran the unlock command just in case through adb and it was fine but still freezes.
Any ideas?
To add to this I just downloaded a dialer app on stock to check bootloader unlock status.
It says bootloader can be unlocked but nothing about its actual status. I'm more or less certain this is the issue now so can anyone advise what to do? I manually tried unlocking bootloader and it just restarted like everything was fine but nothing changed.

I'm not an expert to be honest but I would try that:
put your tablet in fastboot mode, connect it to your pc and in fastboot type
"fastboot flash boot twrp.img"
Now you should have TWRP.
If this work your bootloader should be unlocked otherwise I think you should see some error in fastboot
Once you have twrp I suggest you to flash resurrection remix 5.7.0 (android 6.0.1). I suggest it just because it worked without problem with my tablet Z.
Something not clear to me: you started just with a rooted stock ROM or you unlocked bootloader, flashed TWRP and then your ROM?
I started with rooted stock rom, I am using dual recovery that seems to be working fine (it was faster since its just a bat file). I originally rooted using kingroot on stock which I used to flash stock rom prerooted with supersu with twrp.
If I try the same process with anything that isn't stock it's black screen on reboot. No Sony logo or anything.
Ive tried changing recovery to newest twrp, changing sd card to a different one, different ROMs including the one you mentioned because that's the one I wanted to try. I also tried with and without black kernel. None made any difference. Black screen boot everytime with just a blinking light on side like its got no OS installed at all.
Just to clarify, my bootloader should be unlocked. I've checked but if I run the adb command to check it just freezes like it's eternally loading. Using dialer go check it doesn't even display anything about it aside from the fact it can be unlocked.
what command do you type? "fastboot oem device-info"?
ok so I have an update, something is definitely messed up with my bootloader.
I tried to relock bootloader from fastboot but its also stuck in a loading cycle for no reason. It seems on some level my bootloader is unlocked because I can flash recoveries fine, but when I come to put a new ROM on the device it won't let me and black screens.
From fastboots I used the commands 'fastboot oem lock' and I just get '...' forever underneath. If I use 'fastboot devices' my device is listed, if I use 'fastboot -i 0x0fce oem unlock 0xbootloadercodehere' it fails the first time, then works the second time and says ok but its clearly done nothing when the device reboots. 'fastboot oem device-info' also leaves me with the '...' on command prompt forever too.
I have no idea what to do if bootloader is screwy at all.

Yup that's what I used. I'm pretty sure bootloader is borked somehow though. I tried reinstall from Sony software too which hasn't changed anything.

I just tried with my XTZ and "fastboot oem device-info" just froze, it had 3 dot and nothing else. In my OPO it worked.
I'm gonna search something else...
Whats weird is my tablet also won't install anything on TWRP, I just tried installing SuperSU from it to see if it would work (having to use Kingroot atm) and it just does nothing.
I think this is the issue since I'm factory resetting before installing a ROM, which is therefore wiping my system and when I come to reset because TWRP isn't installing anything its acting like there isn't a system installed.
I can install via ADB fine, just when it comes to recovery... system says no. Its weird because its like its got a locked bootloader or something but even though I reinstalled using Sony software its still the same. If I try unlock bootloader again, I get an error first time then it says OKAY and does nothing.

According to an other post this should mean that your bootloader is locked but can be unlocked via Sony's code. At the same time I've read in the same post (can't find it) that people with unlocked bootloader still have "bootloader can be unlocked" even if they successfully unlocked it...
Unfortunately I can't try it myself because I'm on RR and the code *#*#7378423#*#* (this should be the code you used) doesn't do anything.
I have the code and have used it previously I have also retried it just to make sure.
When I type the dialer code above I get 'bootloader can be unlocked: yes' but nothing mentioning the actual current state of bootloader.
This is what's leading me to think it's a bootloader glitch because all posts I've seen should say 'bootloader unlocked: yes' or 'bootloader unlocked: no'. I get neither.
Been a few days and had no suggestions. Anyone got any ideas at all outside what I have mentioned? Getting pretty desperate because wifi is really bad on stock, getting constant slowdowns and stalls for no reason. I'm gonna end up trying to sell second hand if I can't do anything.

Sorry, I'm out of ideas
The only thing I can tell you is what I did to my XPZ, but I doubt it may help you:
1) Unlock bootloader using Sony's guide
2) XPZ in fastboot mode → from pc "fastboot flash boot twrp.img" (assuming you have the proper TWRP image named twrp in the same folder of fastboot)
3) flashed RR 5.7.0 and Gapps
4) RR change the rocovery to CMrecovery but I "easily" changed back to twrp using a guide under RR thread.
I have tried for multiple hours to get fastboot and ADB to work with my S6 Edge but it is not working. I suspect I might need to try older Samsung drivers (I only tried the latest ones as far as I remember). I wanted these tools in order to check if my bootloader was unlocked so that I wouldn't brick my device if I tried to install a custom ROM and TWRP. Anyway I followed a video and installed TWRP on my phone and installed Lineage OS Android 10 without checking the bootloader since the guy in the video did not mention doing so and still installed the custom ROM and TWRP. It is working fine. I know it is most likely that since this was possible, the bootloader should probably be unlocked but I just wanted to confirm with more experienced smartphone modders if this is indeed the case. Is it then safe to root my phone without checking bootloader?
Sub-question: If a person were to theoretically attmept to install custom ROM or TWRP or root the phone while the bootloader is locked, would that result in the root failing but the device still being usable or would the attempt result in the device being bricked? IE if the bootloader is locked is it dangerous to attempt to flash software to the phone or will it result in a harmless "failed" message, etc.?
Thank you.
