I'm not sure what you guys know about the LG G Stylo (Cricket) scene, but here's a few things about this phone that you should know:
• no fastboot (bootloader) mode
• locked bootloader
• rootable on 5.1.1 (I'm already rooted)
• OEM unlock switch in developer options
• stock recovery sucks (basic, only able to factory reset)
All I want to do is unlock my bootloader, but as I've stated there is no fastboot mode. Sadly, I have no clue what to do about this. I have already successfully rooted my phone using KingRoot, softbricked the phone, flashed the KDZ, and rooted again, so I have a little experience with the software of this phone.
As I've also stated, the Cricket variant (CMDA/GSM) has a locked bootloader AND the OEM switch, so here's what I'm truly asking:
Is there any way that I can write my own fastboot/bootloader mode and flash it via Flashify? If this is indeed possible, I know for a fact that I can unlock the bootloader of this phone and flash a custom TWRP image onto it, helping tens of thousands of people with the same problem. I really love this phone, but I hate being locked down like this, especially with no good recovery to be able to flash a custom ROM if I had to.
If anyone has any ideas, please speak up!

It's looking like, at least for some users, unlocking the bootloader on OTA 4.5.141 is causing more issues than the expected soft brick that happens with 4.5.91. When new users are asking about unlocking the latest version, I see the standard advice offered:
- flash pudding sbf (just the unlocker)
- probably get soft-bricked
- issue "fastboot oem unlock" command anyway, reboot & life is great
OR use the one-click BL unlock script.
-----------------
But Nottach said he nearly hard-bricked after flashing pudding while unlocking a stock phone on 4.5.141. He had to do a vol up + power combo WHILE inserting the battery in order to bring it back...
and this user apparently had to do at least a battery pull to complete the process (not sure since posts were edited)...
and still other users are reporting success with the one-click tool.
-----------------
So: is it a fair statement that BL unlocking on the latest version runs an increased risk of bricking the phone, compared with 4.5.91? Is there something else I'm missing here? If I had a stock phone on the latest update I'd be thinking twice about unlocking it.

Anybody?
Had to replace my Atrix today, new one already has 4.5.141 on it. Is it safe to unlock the BL using pudding? Or should I wait till the Dev's get it fully worked out?
I'll post my experience/method that I did several times over on my 2 Atrix phones (Both AT&T)
Both phones had unlocked bootloader
I upgraded both phones via the Automatic Update (Motorola Website tool...it downloads the SBF and flashes it to your phone)
At that point you're at 141, stock, unrooted (I did this over unlocked bootloader)
Then I used the Automatic Bootloader Unlock 4.2 to do fastboot oem unlock
I root using preinstall method and restore from Titanium Backup
I have not run into any problems going to and from 141 with unlocked bootloader (I did not try going to FroYo but GB works fine)
I release two ATRIX with GB 2.3.6 Version 4.5.141 very easy
Use RSD Lite 5.7
but the pudding in this link:
http://forum.xda-developers.com/showthread.php?t=1136261
First go to applications and places the phone in debug mode, then turn it off, and plug it in RSD mode and flash with RSD Lite SBF
If for some reason fails you failed to boot OS 0x1000 not detected, goin to RSD mode in 5 seconds
Then use this software
http://forum.xda-developers.com/showthread.php?t=1182871
And utliza the Options for Failed To Apply FIX 0x1000 Boot ", the cel should be in fastboot mode
Write down the key will throw you via commands and then put it again when prompted, after this and you will the unlocked bootloader.

When you did this, did you not get soft-bricked? I know I did.

I've done the preinstall, but I can't get CWM to flash the recovery partition.
Can anybody help with reinstalling CWM? Should I flash a pudding / SBF again though I know (based on the contents of ReservedOdm that my BL is still unlocked)?
just wanted to post my experience as i did this a couple of days ago...
i flashed the pudding file (not the one that the automatic unlocker script uses when choosing the 2.3.4/4.5.91 option), got the failed to boot error, put the phone into fastboot mode and did the oem unlock commands (on a PC running winXP), and my bootloader was successfully unlocked. at this point i was able to boot into the stock ROM, with the data partition freshly wiped. i then flashed romracer's cwm using fastboot mode, and then installed the nottachtrix rom. btw i noticed that on the stock rom, cwm would not stay loaded. seems like it gets wiped out after reboot? not sure.
i had previously created a tarball of my data partition and restored it after installing the new rom, but this was a bad idea. better to just use the batch functions of TiBu for the apps, and some sort of sms backup app (from the play store) for keeping your messages.
Just the topic I was looking for. I was trying to unlock my bootloader for this version, but haven't been able to find a guide showing me how and this is my first time.
hey everyone. trying to OEM unlock the TWRP bootloader. When I type "fastboot OEM unlock" it will reboot into TWRP bootloader, and nothing unlocks. I know this because when I type "fastboot oem device-info" it says "unlocked FALSE".
I have OEM unlock and USB debugging enabled.
This is a phone with previously successfully installed CM13, and now I'm trying to revert to stock/unrooted. I can't seem to flash the recovery at all here because I can't get the damn thing to unlock.
Any ideas?
Did you lock the bootloader ? If your flashing Roms and custom recoverys imagine its already unlocked. Bootloader won't lock itself. If you want full stock just flash any OS2 firmware with twrp. You can worry about stock recovery after. I would just leave the bootloader unlocked won't hurt anything.
I had the same issue not long ago. Finally, i used the mega unbrick guide, but warning, all the data is lost
Ps: Sorry for bad english
hey, thanks for the response. I have been following the following tutorial (and others similar for installing CM13):
(great, website won't let me post it here... it's the unlockr oneplus x guide)
so yes, I originally flashed the stock recovery and replaced it with the one from the tutorial. There were a few hiccups during setup, which may have affected why I can't easily update nightly now, so now I'm trying to revert to the unrooted stock state so I can try from scratch, hopefully fixing the issues I'm seeing now. The problem is that I can't flash the recovery using the stock recovery... I can't even update the damn recovery because it's locked. Is this what is meant by a 'soft brick' ?
I have wanted to root my phone for a while but one-click roots definitely do not work. So in my research I've found that using some kind of custom recovery is the next logical step. In doing more research, I downloaded the adb and fastboot tools but then found myself unable to unlock the bootloader. My theory is because I don't have oem unlocking checked, for the reason that it doesn't show up in developer options. USB debugging does though, so I have that checked. At this point I'm at a loss. I've tried all kinds of commands like fastboot oem unlock or trying to go to the bootloader through recovery mode and through commands. None have worked, and the only command that seems to do anything is adb reboot recovery. I was wondering if anyone had any ideas on what I should do next? Thank you!

Check your phone, is it international model? What carrier did you get it through, Verizon & AT&T BL's are usually OEM locked. Which can be a drawback.

It was for straight talk I believe. And from what I can tell it probably is OEM locked. If it is, does that mean it is impossible to root?
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.
Dear Masters,
I bought a 2nd hand LG V60 V600VM from china taobao store and it comes with a customize firmware, i don't like it and flash it back to 30b (android 12) stock firmware using LGUP.
I would like an upgrade from android 12 to android 13 from Verizon OTA but fail, i found the problem should be the phone is still boot loader unlocked.
I search through the web can find many tutorials of how to unlocked boot loader, but can't find one teach how to re-lock the bootloader.
Can any experts shows how to do that? I just want my phone back to stock, everything back to stock, no need root, no need boot loader unlock....
Thanks very much!!!

It's the same as unlocking but when you get to the step fastboot oem unlock, do fastboot oem lock instead.

Done! it works fine, the boot loader is locked now, thank you very much!!!
