Problem rooting Nexus 4 on Mac OS X - Nexus 4 Q&A, Help & Troubleshooting

I am wanting to root my old Nexus 4 because you can apparently use a USB OTG cable with it once it's rooted? I can't seem to get the damn thing rooted though!
I've been following this tutorial, as the second video is specifically for Mac users.
I've managed to unlock my boot loader, and then try to flash CWM, but whenever i reset my phone, it doesn't boot into CWM, just the normal boot screen. I've followed the video step by step and tried it multiple times, with no success.
I've also tried using these one-click methods (the One-Click ClockworkMod Recovery Toolkit version), and I can boot into CWM recovery, but then whenever I restart my phone, I loose the CWM recovery,
Can anybody help me try to root my Nexus 4 on Mac OS X. I don't mind not rooting if there is another way USB OTG can be used with the Nexus 4?

Use TWRP 3.0.0, it's up to date and supported still. The flashing process is the same as CWM: ./fastboot flash recovery twrp-3.0.0-0-mako.img Also, to boot into recovery, power off your phone and hold Volume Down+Power and it will boot into the bootloader, then use the volume buttons to select recovery and power button to boot it into recovery. I use OS X so if you need any help just quote me and I'll try to help out
Edit
If you have ADB downloaded as well in the same directory of Fastboot, you can enable USB Debugging under developer options in Settings on your N4. Type /.adb reboot recovery in Terminal whenever you want to boot into recovery, without having to do the above process that I mentioned.

After flashing recovery, boot directly into recovery after flashing using the volume and power button. Do not reboot the phone before booting into the new recovery. Also, there is no need to power off the phone before booting the new recovery for the first time.

Thanks for the advice. I downloaded TWRP and booted into recovery. I then entered the following into the terminal:
Code:
A-MacBook-Pro:RootNexus4 A$ ./fastboot-mac flash recovery twrp-3.0.0-0-mako.img
sending 'recovery' (9122 KB)...
OKAY [ 0.292s]
writing 'recovery'...
OKAY [ 0.475s]
finished. total time: 0.767s
I then changed the setting on my N4 from 'Start', to 'Recovery Mode' and pressed the power button. It seems to have booted into TWRP correctly. I then chose to restart phone as normal and got the infinite boot sequence of coloured balls swooping in-between each other...
I'm confused whats going on here...

I've now tried to Reboot (through TWRP, and clicked Bootloader, but TWRP says there is no OS installed. Thats probably why I get the infinite boot loop? How can I re-install the OS? I've downloaded the factory image from Google, but can't flash it...

You can manually flash each partition to the phone using fastboot commands. This will restore the phone back to stock.
Once the phone is able to boot the stock rom, reinstall twrp, boot into twrp, and flash supersu.

[Q] MT4G not taking CWM recovery

I'm working on a friend's MT4G after having rooted mine several months ago. The phone I'm working on is perm rooted with s=off. I can go into hboot and it shows s=off. The problem is the phone will not take Clockwork Mod's recovery.
CWM downloads and installs, then gets superuser permission and claims to be flashing recovery, but trying to reboot into recovery doesn't work. The phone boots to the "T-Mobile MyTouch 4G" screen, blinks off, comes back to that screen, then proceeds to boot to stock Android.
Uninstalling and reinstalling CWM just gets the same result - no recovery.
Shutting down completely then hoilding Vol up while pressing power makes the phone vibrate rapidly 3 times, then the LED blinks orange.
Going to hboot, then selecting recovery from there boots to stock Android same as trying to get to recovery through CWM.
How do I get this sucker to take CWM recovery?
It happened to me also, I just kept pressing it over and over and eventually it downloaded the file, If you have your's rooted why not go into your SD card and take the recovery IMG and put it on the other phone?
If you have the engineering screen you can ADB flash it via fastboot.
or you can use the ADB commands from within the ROM to do it.
either way download the recovery image i have posted in this thread. or from koush's web site store just the recovery image on the root of the SD card.
Code:
adb shell
su
flash_image recovery /sdcard/recovery.img
via hBOOT, give you have the .85 hBoot.
1) Download the attached file from the link i showed above and store just the recovery image to your folder from which you preform all of your ADB commands
2) plug the phone into the computer
3) boot the phone into HBoot
4) from the ADB commands change the drive to the folder where you stored the recovery image.
5) type these commands
Code:
Code:
fastboot flash recovery recovery.img
the screen should say something to the degree of
Code:
sending 'recovery' (3426 KB)... OKAY [ 1.172s]
writing 'recovery'... OKAY [ 0.797s]
finished. total time: 1.969s
6) then select "bootloader"
7) navigate to "reboot recovery"
Turns out that particular phone did NOT like CWM recovery 3.0.2.4. Once I got legacy recoveries to show up, I put 3.0.0.5 on it and was able to get into CWM recovery. From there I flashed 3.0.0.6, then put RoyalGinger on it.
Works great now, it's just odd that 3.0.2.4 didn't work on it.

Flashing Recovery no worky - unlocked BL xt1080

Hi,
I have a Droid Maxx XT1080.
I purchased a Moto 360 and my Maxx was running 4.2.2 so it wasn't compatibility. I've never updated cause I had root & wifi tether. I found out sunshine would be able to unlock my bootloader so I did it. I then used RSLite and flashed 4.4.4. So now I have 4.4.4, no root, no wifi tether, unlocked bootloader. I've been trying to flash recovery with TWRP or CWM with no luck. It says it flashed via command prompt and fastboot but when I go to select recovery in fastboot it just reboots the phone. With the phone off and pressing power and volume up, it won't enter recovery as well, just boots straight up.
I don't know if I should just use RSLite to flash the whole phone back to a different state and try again. I just don't want to write over the unlocked bootloader accidentally.
I tried using this recovery method with no luck: http://www.addictivetips.com/android/root-moto-x-install-cwm-recovery-complete-guide/
I've also tried TWRP 2.8
Thanks,
Ambrose
You press volume down and power hold the rocker 1st

Understood, that brings me to fastboot which I then scroll down to recovery and hit the power button to select. I get a blank screen and have to press and hold my power button again for the phone to eventually reboot into Android.
OK what is said via fastboot flashing are you flashing as root/admin?

That actually brought me into CWM, but it wouldn't let me do anything. I just saw the logo in the middle and version number at the bottom. I just flash TWRP and used adb to get into recovery that seems to be working! What is preventing me from getting to recovery from fastboot?
Thank you!
My guess has something to do with it not being made for your device, try flashing moto x recovery first then the custom one
when in fastboot you use vol up to select not the power button. i think this is where you are going wrong.
This should work

I just went through the same thing on a Maxx last night. This is what worked for me
Download TWRP 2.8 from here http://techerrata.com/browse/twrp2/ghost
flash that through the dos windows with your phone booted to fastboot mode.
as soon as the phone resets hold the power and vol down. you must do this fast. Then pick recovery and twrp should boot up. then exit twrp and it should ask you to root, move the slide bar and you all set.

is your bootloader unlocked? if it is this is the command you should be typing.
Code:
fastboot flash recovery recovery.img
just replace the recovery.img portion with the file name of your twrp file.

Still didn't work..
Instead of using RSD or RSD Lite use moto-fastboot. I stopped using RSD a long time ago. I was having an issue flashing the TWRP recovery on my phone but i noticed when I first flashed my phone with 4.4.4 it failed the motoboot.img flash. So when i re-flashed my phone with 4.4.4 and then re-flashed TWRP it finally worked out for me.
Being motorola uses moto-fasboot regular fastboot won't work.

[Root][RS988] Rooting RS988

Now that LG has released the bootloader unlock for the RS988 it can now be rooted.
------------------------------------------------------------------------Disclaimer---------------------------------------------------------------------------------------
This post is meant to be educational and I am not responsible for any lost data or damaged devices resulting from the following instructions
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
-----Instructions on Unlocking your bootloader can be found here---------
WARNING THIS WILL FORMAT YOUR DEVICE
https://forum.xda-developers.com/lg-g5/development/official-european-lg-g5-h850-bootloader-t3363040
The only difference is selecting RS988 when selecting your device
---------------------------------------------------------------------------------------
Requierments:
ADB
fastboot
An RS988 LGG5
The working (though not entirely tested!) TWRP image is found here https://build.nethunter.com/test-builds/twrp/lge/twrp-3.0.2-1-rs988.img (Thank you jeffsga88 for finding this link)
The Latest SuperSu Binary
Step 1:
Make sure your RS988 is fully updated, the rebooting into the bootloader is only unlocked in the most recent updates.
Step 2:
Enable Developer options and USB Debugging
Step 3:
Enter Command
Code:
adb reboot bootloder
Step 4:
Once in bootloader run
Code:
fastboot flash recovery [path to twrp image on your pc]
Step 5:
Turn off the device DO NOT let it boot back into android!!
If you do boot back into android, you will need to re-flash TWRP (Steps 1-4)
Step 6:
With your device unplugged, hold power and volume down, releasing the power button for a moment when you see the LG logo, then
re-pressing the button to enter recovery, on the following screen select yes both times
Step 7:
(The Following Text other than step numbers is written by and entirely created by jcadduono, and can be also found at his post at https://forum.xda-developers.com/lg-g5/development/recovery-team-win-recovery-project-lg-g5-t3363047)
At this point, you will see the TWRP splash and reach a screen asking you if you want to allow system modifications.
By swiping right, you will trigger dm-verity, and if you don't follow step 8 you will be unable to boot!
If you are going to root your device or follow the rest of these steps, then it is safe to swipe right and enable modifications.
Step 8:
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
Step 9:
Please consider backing up your stock boot partition in TWRP before proceeding to the next steps!
Step 10:
If you want to be rooted with SuperSU:
Download the latest SuperSU stable by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
-or-
If you only want a bootable system partition or writable data in TWRP:
Download dm-verity and force encryption disabler.
Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.
Step 11:
Go to [Reboot] -> [System].
---------End of jcadduono post clip-------------
Now upon reboot, the phone may loop a few times and take up to 5 minutes to complete the process.
When you get into the device, run through setup as normal and you will have SuperSu installed and you will be rooted.
I can not verify Magisk Root Yet but will be attempting to do so soon.
You guys that have the rs988 you may want to ask one of the devs to add support for LOS and custom ROMs. But don't bug them either.
Maybe @King_lilrowrow could help if he has time, although I know he's been busy lately with other things. Hopefully someone will help you guys out. I have no idea how to, otherwise I would try and help. Nice you guys have rootr and twrp finally though.

After flashing recovery, unplug USB cable and pull battery.

One at factory reset screen select yes both times and you'll enter TWRP. When using the buttons remember to never let go of the volume down button only the power button for 1 second at lg logo.
You can also try after flashing it:
adb reboot recovery
Note: you must reflash TWRP if you allowed it to boot into os without flashing SuperSU or magisk.

No problem! Glad we finally have it on RS988
I've held off on unlocking the bootloader and rooting, since it seems there currently are no ROMs available for the RS988 to flash. Basically you just end up with rooted stock?

Yes, currently all you can do is install TWRP and root stock. You can also install some audio mods like viper, but no custom ROMs yet for this version of the device.
Is there a touch TWRP recovery available? Granted I'm not sure if I will be able to flash it, since my power button is broken.

Yes it's touch TWRP, can't even remember last time I saw a non-touch based one, been at least 3 years or so. Anyways it's located in the op. As far as flashing it, I believe you can do it without the power button. The issue will be rebooting to recovery after flashing it to flash SuperSU or magisk (if you don't do that or at least get into TWRP before first bit after flashing and delete the recovery from boot.p file, TWRP will be overwritten by default recovery and you have to flash again). While in fastboot mode, after flashing you could try and use:
Code:
adb reboot recovery
Not sure if that will get work or not while in fastboot mode, but something to try since your power button is broke.

You can always check using LG bridge and use update feature. If just wanting to know because your wanting to root and get TWRP, try and follow the guide. If you're not on latest version you'll know because you won't be able to unlock the bootloader using fastboot. If you can unlock your bootloader, you're good to go.

[SOLVED]Tried to update Magisk from app, stuck at Fastboot screen, TWRP may be gone

I fixed the problem by just booting into the LG Factory Reset menu, in order to get into TWRP. I hesitated to do that for a while because I had no way to verify TWRP was still on my device. After running out of options, I decided to just go for it. To my (and probably no one elses) surprise, it went straight into TWRP, where I was able to flash H91820s and Magisk 16.0 in the same TWRP session. Rebooted, everything was how it was except on a new version of Android. Root was retained.
Tried to update Magisk on my TMobile H918 from Magisk version 16.x using the app, and selected Direct Installation. The device is now stuck at the fastboot screen, and I cannot boot into recovery from adb.
Is there a way I can repair things? I am unsure exactly what got deleted/corrupted in the process of the update.
EDIT: When I try to boot into TWRP, I get this error:
fastboot: error: cannot load 'recovery': No such file or directory

and when I try to re-flash TWRP, I get this error:

Can you get in Twrp with button combo? For me its while boot hold vol down and power then at lg logo release the power for a sec and re hold until the while screen and then select yes twice.
There is also download mode and reflashing twrp that way I believe...

I tried to boot into recovery, but adb detected no recoveries on the system.
I don't want to do the System Format Yes Twice thing because I believe TWRP is gone. And I am unable to re-flash due to "no such command."
The recovery is unable to be written to the device.

Rebooted, everything was how it was except on a new version of Android. Root was retained.

I fixed the problem by just booting into the LG Factory Reset menu, in order to get into TWRP. I hesitated to do that for a while because I had no way to verify TWRP was still on my device.

Unable to boot into newly-flashed recovery from fastboot (LineageOS 18.1)

Recently got a hold on the T-Mobile version of the OnePlus 6T. Already have a OnePlus5 running LineageOS as well and thought the installation would go as smooth.
Following these directions, I got through unlocking the bootloader (with the unlock_code.bin from OnePlus) and I thought I'd gone through flashing a custom recovery. I was able to boot into fastboot, ran # fastboot flash boot lineage-18.1-20210506-recovery-fajita.img, and shutoff the device. Now I'm stuck in a bootloop at the screen indicating that the device has been unlocked and data can't be verified.
While still connected to my PC, any combination of Power + Volume keys will flash the display and instantly go back to the bootload screen. The only way to shut-off the phone is to disconnect it and do either Power + Volume Up or Power + Volume Up + Volume Down; Power + Volume Down to try and boot into recovery does nothing. Plugging in the phone while off auto-starts it back to the bootload loop.
I can turn on the phone while disconnected, but the only way to escape the bootload loop is to boot straight into fastboot with Power + Volume Up + Volume Down. From here I can connect it to the computer and it's seen as a fastboot device. From here, however, any of the options will reboot into the bootloop.
Is there anything I can do from here? It's not a hard-brick, but I'm not sure why I'm stuck in a loop. The flashing of the recovery seems to have worked, no issues with A/B as stated could happen in the docs. I'm at a loss.
Code:
Sending 'boot_a' (65536 KB) OKAY [ 1.573s]
Writing 'boot_a' OKAY [ 0.365s]
Finished. Total time: 1.947s
Data can't be verified? It does let you run fastboot commands, just not send files?
Most people on this device use TWRP. I have a guide here.

Yes, I can get the fastboot menu, but trying to boot from the lineage recovery image would take me straight to the warning page indicating the device is unlocked and to not store confidential data.
I just tried using the guide you posted to go with TWRP, but I'm having issues again with booting the recovery. Followed every step: downloaded the ROMs, flashed them all to the phone as per your script, was able to boot, chose the language and wiped, and once in the phone rebooted into the bootloader. But similar to before, I run # fastboot boot twrp-3.5.2_9-0-fajita.img, but now the phone seems to be stuck on the OnePlus logo with the words Fastboot Mode underneath.

You may need to start over. I the unfortunate part here is the TMobile 6T is a bit different and complicates things. Recent TMobile MSM Tools have been posted in the TMobile thread, they just aren't in the OP. I'll be honest I don't follow the TMobile devices, so I don't know much about what's best to use between versions and international tools and what not. There are a few TMobile users that posted in my Guide thread that you may want to tag and see if they can help?
