This is a thread to see if anyone has ideas on Unlocking the Bootloader & porting/creating CWM or TWRP to our device? Any ideas are helpful and welcomed.

I'm not to sure, I know you need the bootloader unlocked for Roms and Kernels
EDIT: I thought about it and your right, you always have to unlock the bootloader before you install the Custom Recovery.

Are you sure the bootloader needs to be unlocked in order to install roms?? Thought that was only for custom kernels. Moto devices have always had pretty locked down devices, yet had recoveries and ability to install roms, if I remember correctly...

Why should I unlock?
The explanation to this question is really simple. If you want root, you’d be wanting to flash Custom ROM post-root, and if you want to install a Custom ROM, you’d need to have your stock bootloader unlocked. In simple terms Unlocking the bootloader allows you to install custom Firmware on your Android phone
Warning: Unlocking your phone’s bootloader voids its warranty. It also completely wipes (formats) your Android phone’s internal memory including applications, contacts, SMS and MMS messages etc.

kexec is required to flash a kernel.
Safestrap is a way to flash somewhat custom ROMs (without kexec you need to use stock kernel) without recovery installed but it needs to be adapted to each specific phone. Right now I think they are working on a version that will work with the S4, not sure how attractive the G2 is (or will be).

http://forum.xda-developers.com/showthread.php?t=2443165 <---- these guys are the ones who worked most of the magic for Optimus G (and Pro?).
You guys first need Root to do anything (which i believe you have). Then you need a Custom Recovery. Installing a Custom Recovery can be accomplished via a workaround or by unlocking the bootloader. A workaround like loki by djrbliss on the Galaxy S4 which isn't an unlock but more so a bypass or like Safestrap by Hashcode.
Here is the man djrbliss.

I found it. server is chat.freenode.net room is lg-g2. Not very much going on in there at the moment.
i completely agree with the said explanation. but I'm having difficulties with my device i.e. LG G2 (D802).
I'm rooted with custom recovery TWRP and unable to install most of AOSP roms based on 4.4 KitKat. New Custom roms are coming up very frequently now for this device but so far I'm able to flash ParanoidAndroid Rom and modifited stock rom... Apart from this I always gets error while flashing the rom.
Most of the time Error comes up saying 'Status 7 Error' and 'unable to execute update binary'.
I did google on this subject and tried everything i found but the problem still exist.
I never had these problem flashing LG Stock or Android 4.3 based roms. Need advise on this subject. By the way any help on unlocking the bootloader????
thanks:good:

Not sure if i posted in the right section...but i purchased a Sprint galaxy s4 a couple months after it was first released and it was unlocked. I am a person thats pretty knowledgeable about rooting and roms and what not, but buying a that was rooted and unlocked i dont know where to start or go from here or even what the phone has. All i know is...it has a custom recovery (twrp) its on MDL android 4.2.2 and a kernel version of 3.4.0 ([email protected] #1) and it running a stock rom. Another thing is...i dont understand if its supposed to be unlocked doesnt that mean i can travel abroad and use a sim from whatever country im in? I tried and it didnt work. My gf's verizion s3 thats not unlocked or anything did happen to work..like wtf?
Anyway, to break things down...im looking for where can i go from here? should i start from scratch? I feel like im out of the loop with everything and looking for something to give my phone a face lift but i maybe want to stick with a stock rooted rom...whats out there? and also my phone is getting pretty annoying with wanting to install MF9.. posting this on xda also..thanks

Well you're currently on a pre Knox bootloader so I'd stay right there and just flash the rom of you're choosing to update. You can also flash a different modem as well and update that way without taking an ota. I'm running Carbon 4.4 and it's a pretty sweet rom but you'll have to decide which is better for you.
And as far as using the phone abroad I'm not really sure. Someone else can probably answer that one better than I can.
I know my Verizon S4 can go abroad not sure on sprint but I'm sure the answer is on here somewhere search it out.

Hi! Thinking of getting the G2 on Verizon. However, I want to make sure that it's not so locked down that I can't flash CM on it. Can anyone give a geeral state of affairs on the development scene on this phone?
You can flash custom ROMs on it. The bootloader is still locked, but there's a workaround (loki).

Pretty easy if you do some research, I had some issues after taking the 12B OTA before rooting and trying any custom ROMs and ran into some snags.. I rolled back to a previous version and it's been very hassle free using TWRP 2.6.3.3. Gr33nd3vil's unofficial CM has been running very nicely
I may have messed up, but I am not 100%, not use to Samsung Devices.
I have a developers edition S5.
I tried to run updates but it would not take any update OTA even though there were two, NCG was the current room.
I flashed the ni2 via odin.
Now on the screen, instead of Mode: Developer, it says Qualcomm Secureboot.
I am not sure if I relocked the bootloader, if it can be unlocked,
Or this just the need to go into a recovery and flash a different rom.
Did I relock the bootloader?

I believe you have. But first I need to ask you 1) were you rooted and 2) did you have a custom recovery (TWRP) on your phone before you ODIN'd NI2? If you had TWRP on your phone before ODIN can you get into TWRP recovery now? Just an FYI, Samsung does not send out, in any form (OTA or otherwise) updates to the Developer Edition phones. The explanation for why they don't is long and no one except for Samsung knows for sure and they are not commenting on the issue. Dev owners keep their phones up to date by flashing custom ROMs released by our Dev community for retail and dev edition phones.

When you flashed the stock tar you locked the bootloader and unfortunately you will need to contact Samsung and explain what you did. Most likely you will need to send the phone in so they can unlock it again. Contact them first.

I think you're right Misterxtc, unfortunately all Samsung is going to do is return him a retail version of the S5. According to 3 other Dev owners that locked their bootloaders all Samsung would do is return their phones to working order, but no unlocked bootloader.

That doesn't sound too promising. They really need to change their policy on that.
im not sure why you would have flashed a ne9 tar when instructions clearly say NOT to flash odin tars on a dev edition s5 because it will lock the bootloader

Thank you all.
Yes the phone has been locked. Obviously I blame myself for not researching and just assuming.
If there is a silver lining, it appears my phone has a bad microphone, when I called, Samsung wanted to do an warranty exchange. I told them it was a new item less than 5 days, so I am just going to return.
Still debating if I should wait a few month and get the S5 locked from VZW as I am not seeing a lot of dev (although it makes it easier to root), or if I should get another model of phone all together, or reorder the S5 Dev Edition.

I hope Samsung does right by you. Just my opinion, but I think the Developer Edition S5 is the best phone on the market right now. The only other phone, that I know of, that allows the user the flexibility and performance of a unlocked bootloader phone is the HTC M8. The M8 is a good phone no doubt, but I like the S5 better. True, there aren't that many ROMs rilght now, but more and more get added as time goes by. The ROMs that are available are good, staple ROMs and range anywhere from super customization available to the user to lean, debloated super fast with great battery life...and a couple in between. Your choice, but if Samsung will replace your Dev Edition with a new Dev Edition...I think that is your best bet right now. But that is just my opinion. Good luck.

Thanks, Samsung is def returning the Dev phone without a 15% restock (have rma). Not because of the locking, but because of the mic. I think you are correct.
I had to go to my standby which is the dev Moto X. Love this phone, but the photos are bad, and it is slow. When I confirm the credit has been giving for the Dev phone, I will reorder the Dev edition. This time I will have to figure out a way to make a backup for resell, and flash only using TWRP.

I've always been a Moto fan myself, but although they still make good phones, they're not great phones (camera, display etc). I just post a "Do's and Don'ts" for Dev owners. Give it a read and let me know if I should add something to the thread. I've seen six users brick their Dev S5s in the past couple of weeks, hopefully the thread will help the next guy from making a mistake: http://forum.xda-developers.com/verizon-galaxy-s5/general/developer-edition-s5-dos-donts-t2895563

great read. (I my case I would have still been returning my phone, but the next S5 will be safe )
The only add, if even possible. It is possible to backup the stock recovery before installing TWRP. So when it is time to sell, you can return the TWRP original backup and flash the original stock recovery?

That's a great question and one that I have been trying to figure how to do. I am not sure about this, but in order to backup a stock recovery you would have to use ADB and do a total backup of the phone that way. I have never tried that and I don't know for sure if it will even work using ADB. Here is how I look at it...who would want to pay $550 (or less) for a Developer Edition phone and never replace the stock recovery with a custom recovery? It doesn't make sense. In fact, the only way you can tell that a Developer Edition phone has not been inadvertently "locked" (not trying to stick a finger in your eye here) is to ask/see if a custom recovery is installed. If not, then there is no guarantee to the buyer that the bootloader is truly unlocked. SafeStrap does not count!
I'm currently running a rooted qualcomm vzw s7, on echoe rom.
I'm aware that the bootloader is on lockdown, but this thing really needs a custom recovery!
The vzw S5 was capable of using Safestrap as a pretty clever alternative to having custom recovery access whilst having a locked bootloader.
My main question is.. is this possible for the VZW S7?
I want to test the vzw s5 safestrap on this phone, but I'm hesitant because I really don't want to have to start from the beginning if this doesn't work..
Any ideas? Has anyone tried this?

Not going to work. It was a work around for a different phone. The developer gave up on that a long time ago.

Even if it was available/possible it is just as effective at custom roms as flashfire. You can only flash stock, un touched kernels, and if you were to flash any other than the engi boot kernel you would get DM verity issues.
