[General Questions and Answers] Droidriven:
First, just to make sure that you are not walking blindly into some potential traps.

1) download the root checker app from Playstore, use it to verify whether the device is actually rooted.

2) power the device off, wait 5 seconds, hold volume up+home+power, when it boots past the logo, let go. It should boot to recovery, tell me what you see. Does it say TWRP with grey buttons on a black screen? Or does it have an android lying on his back and have options listed?

3) verify whether or not the bootloader is unlocked or not on your specific device model number with your specific build number/android version, if it's locked it will create problems if you try to flash custom recovery. Though you can flash CF autoroot with locked bootloader.

Then I'll help find what you need to do what you are looking to do. It may be simpler than you think.

If he in fact used Odin and the device is rooted, he did one of three things.

1) flashed custom recovery(TWRP) via Odin then flashed SuperSU.zip to root, not possible with locked bootloader.

2) flashed CF auto root via Odin, potentially leaving stock recovery if your bootloader is locked.

3) flashed a pre-rooted stock firmware via Odin, not likely though.

The first 2 being more likely than the last one, the second one being the most likely if your bootloader is locked.

[MENTION=5691352]Droidriven[/MENTION] Thank you for the info. After a rough night of research i realized what i need to do. According to root checker, my phone is not rooted, and the recovery seems to be stock. This is very weird, since the phone is obviously not just the stock version that came from T Mobile. Im guessing its probably a badly done root or one that was removed. Anyways, this is how i am planing to proceed:

1. Turn on OEM Unlocking and USB Debugging from developer versions

2. Download CM Autoroot for my specific phone ( i do not know what is the difference between "normal" root and autoroot, but autoroot seems to be simpler and offers the same thing. Please correct me if i am wrong, i would love to know how to do a manual root as well if it has more benefits).

3. Volume down+home+power to get to the download screen

4. Launch Odin that comes with the autoroot package

5. Plug my phone into the USB and wait for Odin to add it.

6. Select the autoroot md5 file from the folder and begin the flashing process

7. Hope for the best and that my phone is still functional when it auto reboots.

After this i should check with Root Checker weather its properly installed or not. If it is, and i see the SuperSU application i continue to installing the custom recovery ( through some research i found out that TWRP is the best choice for me). Installing the custom recovery should be as easy as auto rooting the device. I should download the files from an official website, and flash them using the same process i did for AutoRoot.

After that its mod heaven. With my understanding so far, TWRP lets me install custom roms, and other things i might need.

This is what i plan on doing as soon as im done with a little more research. If anyone has any tips, corrections or general information on what to expect or do please share.

Many thanks to every contributor on this thread.

I would recommend using the command line to flash the twrp instead of the GUI if you want a simple process in linux

Run a terminal as a superuser (sudo)

heimdall flash –RECOVERY filename.img

Do step 1 and 3 you gave before before doing this

Or just flash the twrp image using Odin

J500FN twrp

[General Questions and Answers] luan96:
I'm going to use Odin for this. Since I'm quite new to the rooting community I dont want to mess things up on the first try. I'd rather get comfortable with some standard stuff before I proceed to try different variations. Thank you for your input. Though I would still like to know if I should use cm auto root or do a manual root. The difference is not quite clear to me yet. Again, thank you for your input, it is appreciated.
[General Questions and Answers] Droidriven:
Flashing CF autoroot will simplify rooting, again, just make sure you have the correct autoroot for your specific model number and firmware, flashing the wrong one can softbrick or hardbrick your device, this would require flashing stock firmware via Odin to repair if softbricked and more serious methods to restore if hardbricked. There isn't much difference in effect with the different rooting methods. They all get the job done about equally.

Just make sure that you verify that your bootloader is in fact unlocked BEFORE you flash TWRP. As stated earlier, if it is locked, it will certainly cause issues and you'll have to restore stock recovery and/or stock firmware.

As long as your bootloader is unlocked then your outlined plan should be good to go.

[General Questions and Answers] luan96:
Well, looks like i messed up somehow. I was fiddling around the recovery mode and Odin mode. Those were the only two screens i could view besides normal booting, so i was looking for any info.

Recovery Mode https://ibb.co/hotYZ5

Odin mode 1 https://ibb.co/nFfVE5

Once on the recovery mode, i selected "reboot to bootloader" hoping to find info if its locked or not. I got redirected to this screen

Odin Mode 2 https://ibb.co/kqhtZ5

And then i did what i think is the dumbest thing this year....i removed the batery and now when i try to turn on my phone -

Blocked https://ibb.co/kkOd1k

Please tell me i did not brick my phone without even trying to root it first. My understanding is that i accidentally wiped the current OS (softbrick?) and now i have to flash a new one and then continue with what i had planned. Or is this a small problem that can be fixed easier? Or a more serious one ? Good news tho maybe, i think that the bootloader is unlocked ?

Thank you [MENTION=5691352]Droidriven[/MENTION] for your info so far, you have been extremely helpful.

*EDIT* - Pictures didnt link correctly.
[General Questions and Answers] Droidriven:
It looks to me like they attempted to root the device but didn't do it correctly.

FRP can be a pain to deal with. Some can be bypassed easily, those that have trouble bypassing must sign in with the original owner's original Gmail and password used to activate the device.

The method of bypassing FRP varies from device to device.

Did you factory reset in recovery? If so, that's why you FRP blocked you.

If you have stock recovery then you should not have been able to wipe out the OS using stock recovery, typically, only custom recovery can do that, unless you did something accidentally that somehow corrupted/wiped your OS.

If the OS is gone, you'll have to flash your stock firmware via Odin and start over from the beginning.

Thank you. At least its not just a paperweight. I'm installing new software on it with Kiesk 3 right now. Hope that works so i can do the rooting and TWRP install soon. I pressed "reboot to bootlader" to try and find out if its locked or not, but then it got me in download mode (without having to press up volume to contionue). After i turned off my phone by removing the battery, the OS was gone.
[General Questions and Answers] Droidriven:
Did you get this restored with Kies?
[General Questions and Answers] luan96:
Yes, i did. Worked like a charm, and even got the new 6.0.1 android on it. Also installed TWRP, and just finished installing Xposed Framework, now waiting for it to boot up ( i hear it takes some time). Seems all well so far. If any problems pop out ill be sure to post about it. Also thinking about making a new thread just to help newbies like me who really just want to remove some bloatware, and install some nice modules and not heavily mod the phone. You have been very helpful during this process. Many thanks to you ^-^ .
[General Questions and Answers] Droidriven:
If you have issues with Xposed causing a bootloop, you can flash the Xposed uninstaller zip in TWRP to remove it, then troubleshoot why it bootlooped and try again.

Are you using the Touch wiz marshmallow Xposed framework?

Hello guys, I messed up my twrp backup, and I can't back to stock rom without 7.0 ruu. Does anyone have it? :confused:
[One (M9) Q&A, Help & Troubleshooting] Flippy498:
If it's not listed in the ReadMe thread you only have the following options for getting it (none of the options is available for free - sorry:

Getting S-OFF and flashing the 3.x RUU for your SKU. (Infos are located in the ReadMe thread.)

Contacting Llabtoofer's RUU service. (A link can be found in the further reading section of the ReadMe thread.)

Searching on sites like ir-file or easy-firmware for the needed RUU. (If you choose this option you'll need your phone's codename which is HIMA_UHL.)

Remember Android N CyanogenMod Beta? Let's create another one for Android O! I loved those times. If I was a developer, I would have started it already :crying: but I'm not, so I'm asking others...

[OnePlus 3 Guides, News, & Discussion] _Man0waR_:
It's never too late to become a developer. When you have a problem, do you always wait expecting someone fixing it for you ? I hope not. Don't waste your time crying and waiting, nobody was born as a developer. Start learning now, you'll know already a lot before Android O is released on your phone.

I would think such things would motivate developers. "Wow the community wants this quicker, I'm gonna show them I'm capable" something like that lol
[OnePlus 3 Guides, News, & Discussion] niwia:
I don't see anything wrong with a thread to discuss the upcoming roms. It's cool
[OnePlus 3 Guides, News, & Discussion] zelendel:
No not even close really. See here is something many users dont understand. Developers dont make things for them (ok some glory hounds do but those people are normally complete idiots) Developers make the roms for themselves and decide to share it. Why do you think most teams do not support a device they dont own? Developers have no desire to prove anything really. To be honest, the real developers are some of the most anti-social people you will ever meet. This is the reason most dont even bother posting. They use other people as their voice.

As for fast. Well you can get something fast or you can get something done right. Considering there are no blobs or kernel source for this device anything that does come out before 1+ releases their update will be nothing more then a cheap hack.

No it won't. I would keep TWRP just incase something happends. Also I prefer Magisk over SuperSU. It has a ton more features and is alot more user friendly and it will persists during system updates.

Hello, today i flashed one of the new nougat stock roms. The first boot was fine, everything worked perfectly . But after rebooting I've got the "your device is corrupt. it cannot be trusted and it may not work properly" message, and it wont boot anymore. I cant go into recovery and i cant go into download mode because i get the same the same message and the phone reboots. i can only access the fastboot mode for bootloader unlock, and apparently that my bootloader is now locked. So I've tried to unlock the bootloader again, but it says "Wrong Bootloader Unlock key". Anyone has any idea?
[G4 Q&A, Help & Troubleshooting] Mr.FREE_Bird:
I have the exact same problem and to be honest I think we are f*****. I haven't found any way to re-unlock the bootloader since it seems that the unlock.bin doesn't match with the Device-ID anymore.
[G4 Q&A, Help & Troubleshooting] Pif0u:
This is an IMEI problem. It goes to 0, so the unlock.bin no longer works. I also had this message but my phone was still booting. So I was able to solve the problem.

But you, you can not start your phone, so I do not know how to fix your problem. Sorry :(
[G4 Q&A, Help & Troubleshooting] Mr.FREE_Bird:
No it isn't an IMEI problem, I can reboot my phone and I can access the download mode to flash a KDZ which I did.

Hhmm maybe you aren't totally lost, you can access Fastboot mode right, so how have you tried to access the Download mode? You pressed the Volume up button and connected your device with a USB?

It seems you have the same problem as I had, your IMEI turned into a "0", that's why your unlock.bin fails to flash. Just try to access the Download mode for a couple of times, maybe with a but of luck it wil boot into Download mode eventually.

[G4 Q&A, Help & Troubleshooting] :
I think iv locked fastboot

Well i think i am having the same problem, i flash with twrp stock N...every thing went ok.

When i rebooted the phone had the boot logo error, i am guessing thats the N error for unlocked bootloader, ok no biggie. So the phone boots normal everytime but i cant get back in to recovery. So it seems the rom has lost twrp... If i hold power key and volume down hardware keys to get onto recovery the phone just restores the N rom. I have tried getting in to fastboot but pc wont reconise adb or fastboot even tho its showing in device manager

So 1. I cant get fastboot

2. I cant install twrp

3. Im not rooted

4. I feel f****d lol

It feels like iv blocked the bootloader semi bricked like i ccant run anything over then stock no root.. Fortunetly i can still use the phone.

I think im going to try flashing a mm rom through lg up or flash tool, but everytime i tried that in past it says error connecting to server try again later...so im lost

If anybody has a idea of how to sort this do please let me no. Thanks rob
