[Q] Can I root 4.3 without flashing customer recovery

I had rooted my Nexus 4 when on 4.2.x by putting it in bootloader mode first and typing fastboot boot <name of twrp custom recovery>.img at the command prompt to reboot it into TWRP custom recovery mode without if actually flashing the TWRP recovery on the device. Back then, this temporarily recovery mode allowed me to flash the supersu update zip file I needed to. Since 4.3, this command reboots the phone, but the screen is now blank, and I can't flash the zip file. I can reboot the phone normally into stock recovery mode using the volume keys and power button, but this does not allow me to flash the zip file to root it. Can I still use fastboot boot method like before, and how? The reason I want t stay on stock recovery for now is to keep future OTA updates from throwing an error message.

This is still possible but the command for booting into custom recovery changed.
This helps.

The short answer is no, you need a custom recovery to install superuser. The long answer is you can flash a custom recovery and install superuser and then flash back the stock recovery. If that doesn't work then your out of luck.

You are absolutely wrong. I just booted into TWRP without flashing it and rooted my Nexus 4, which is otherwise stock 4.3. I still have the stock recovery on the device and can access it using the volume keys. Booting into TWRP was a temporary state achieved using the command line syntax:
fastboot -c "<your_default_command_line> lge.kcal=0|0|0|x" boot <name of custom recovery>.img
The 4.2.x version of this command was simpler, as it did not require the -c "<your_default_command_line> lge.kcal=0|0|0|x" part, but you do need it on 4.3, or the device just temporarily boots into a blank screen, instead of the custom recovery. So the long answer is you do need to boot into a custom recovery, but it does not have to be flashed to the boot partition. With a Nexus 4, you are never out of luck.

Follow @efrant's guide. Section E is enough assuming you are on stock android.
That will do the trick.

Sorry for asking about your reason, but if you install the TWRP (or some other) custom recovery then can't you simply manually flash the OTA yourself? That's how I upgraded to 4.3.

In your original post you said you tried using the boot into recovery method and it didn't work so how am I wrong in saying that your only other option was to flash the custom recovery, install su, then flash the stock recovery all without rebooting? It was just another way of accomplishing the same thing. I posted at the same time as the other guy did who knew the new fastboot command, which I was unaware of and obviously you were too.

I just prefer the command line booting instead of having to flash a recovery twice. I already knew that I could flash the custom recovery to get it done, although I didn't clearly state that in the original post.

[Guide] Flash 6.0, root, and no-forceencrypt from stock (easy method)

Hope this helps.
1. Install android sdk and use the included install manager in the sdk to install the latest google usb drivers and platform tools (platform tools include fastboot and adb). Make sure adb and fastboot directory is in your Path variable as well.
2.Download latest stock image for Nexus 9 from google: https://developers.google.com/android/nexus/images?hl=en
3.Download latest twrp (here is the latest right now 10/6/2015): http://forum.xda-developers.com/nex...recovery-twrp-2-8-2-0-touch-recovery-t2944788
4.Download either a stock boot image with the no- forceencrypt flag set or a kernel with the no-forceencrypt flag set
a.I use the elementalx kernel (10/6/2015): http://forum.xda-developers.com/nexus-9/orig-development/kernel-elementalx-n9-0-02-alpha-t2931657
b.A stock kernel for the MRA58K build with the no-forceencrypt flag set can be found here (boot.zip): http://forum.xda-developers.com/nexus-9/general/marshmallow-factory-images-available-t3218290/page3
5.Download the latest supersu that works with nexus (beta now) : http://forum.xda-developers.com/apps/supersu/2014-09-02-supersu-v2-05-t2868133
6.Make sure you have usb debugging enabled and ability to unlock bootloader (android developer options menu on nexus).
7.Unzip the 6.0 stock image into a folder and open a command window in the folder.
8.Type the following:
a.adb reboot bootloader, wait until nexus boots into bootloader
b.fastboot oem unlock
c.flash-all, now wait a few minutes while the stock image flashes
9.At this point your nexus will reboot. Once you’re started, up you need to again enable usb debugging and the ability to unlock your bootloader in the android developer options menu. Now type the following to flash TWRP:
a.adb reboot bootloader, wait until nexus boots into bootloader
b.fastboot flash recovery twrp.img (or whatever the image filename is from the twrp download).
10.Important: now make sure you boot DIRECTLY into TWRP via the button combination (power and volume down), a fastboot command, or the fastboot menu. If you don’t TWRP will be deleted and you’ll need to reflash using the last step.
11.Once in TWRP, hit “cancel” when asked for the password and then erase/wipe data and make sure MTP is enabled (dig around the menus in TWRP, it’s all in there somewhere). This erases the encrypted partition and allows you to use adb to push files to your sdcard.
12.Now type adb push supersufile.zip /sdcard/supersufile.zip, make sure you’re typing from the correct directory.
13.Install supersu via the install menu on TWRP.
14.You now need to install a kernel with the no-forceencrypt flag set:
a.If you want to install a custom kernel (like elementalx), type adb push elementalxfile.zip /sdcard/elementalxfile.zip, make sure you’re typing from the correct directory. Then use TWRP to install the zip from your sdcard.
b.If you want to install the modified stock boot.img then unzip the boot.zip, boot back into the bootloader and type: fastboot flash boot boot.img. Make sure you do NOT boot back into the android OS before doing this step or you'll have to reflash twrp.
Reboot and you’re good to go.

Didnt work for me.

Flash-all script doesn't work for everyone use these steps:
Code:
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot –w
fastboot flash boot boot.img [unencypted if wanted]
fastboot flash cache cache.img
fastboot flash recovery recovery.img [twrp usually]
fastboot flash system system.img
fastboot flash vendor vendor.img

You can't just flash latest stable SuperSU, you need SuperSU 2.50+ beta and a modified boot.img. Instructions here: http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344

I flashed the latest supersu and the latest elementalx kernel.... been running it since about an hour after elementalx kernel for 6.0 final was posted....... everything seems to be working fine. Are you sure? Maybe i'm having no problems with supersu because i'm using elementalx? let me know the reason, i'll check it out on my tablet and see if i can reproduce, and if so i'll modify the guide. But after about a day and a half use, i've had no issues. thx for quality checking.
gt

Am I missing something?
can I not just do a wipe and flash the img with twrp like a custom rom? Edit: Got it working. For me it was much easier to use this as opposed to the android sdk, because it would not detect my version of java. From there I followed your instructions, mostly. Putting the files you posted inside the directory the mini adb client allowed the flash-all command to work. From there I followed chainfire's instructions on the latest SU. Everything seems to be running smoothly. Thanks for the initiative, OP :good:

i used supersu 2.52 due to it seems be be required by the guides and i get the notification that the binary needs to be updated. i have not done that yet. is updating the binary something i should try to do? or, if not is it ok to turn off notifications from supersu? thanks.

I was facing same issue, then updated fastboot(android-sdk) and flash-all script worked fine for me.

That should work as well. That sequence of commands should work with any fastboot version. Just make sure to flash the vendor.img, some scripts don't use that as it's only used for the Nexus 9.

Why so complicated? I just installed @wug's NRT toolkit(on a Venue8 pro) and it did everything for me. Now im on rooted stock 6.0 with disabled encryption. Only thing i needed to do is to flash latest super su beta 2.52, that's it.

- your device is corrupt
- google screen
- twrp (it flashes quite quickly, error messages on mounting everything and last line says something about renaming and something about stock rom)
loop
any ideas ?

Did you make sure to flash vendor.img?
You might try flashing the regular recovery first and then boot in, turn on oem unlock and adb, and then flash twrp and modified boot.img, then reboot into twrp (don't boot normally or it will erase twrp) and flash SuperSU.

yes, that seems to have been it
flashing TWRP seems to have been the problem so I have left everything as stock until root etc works on the stovk kernel

Help with bootloop

Hi,
I did search, but I didn't find any solution to the issue. I got the Nexus 6P 64 GB.
I unlocked my bootloader using the 6p Multitool. Thereafter I used my normal method of fastboot (Minimal ADB) to flash the boot.img from this thread http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344.
After that I flashed TWRP. Basically I followed the instructions here: http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928.
But my phone is not booting up.
It gives me this error:
Your device software cannot be checked for corruption. Please lock the bootloader."
But I tried that and it doesn't work. I tried from fastboot restoring to factory, but get the same message.
Please help me!

Did you check the enable oem unlocking in developer settings?
Sent from my Nexus 6P using Tapatalk

Yes. As I said, I achieved the unlock. Now I just can't get back into my phone or recovery or anything other than fastboot (where it says unlock)

isn't "Your device software cannot be checked for corruption. Please lock the bootloader." the new msg on boot when you are unlocked, and you have to wait ~10 secs before it startup ?

After that, I'm stuck on the Google screen. It just goes on and on. Left it for over 20 minutes at one point and it didn't get past it.
Edit: The multicolored animated google screen. The animation just keeps going and going.

Del.

Your issue might be due to the encryption of the phone. Take a look at this thread: http://forum.xda-developers.com/nex...recovery-twrp-2-8-7-0-touch-recovery-t3234976
From this thread:
NOTE: Decrypting data is not supported yet. The Nexus 6P will normally attempt to encrypt the device automatically on first boot. To use TWRP as you normally would, you will have to format data and install a slightly modified boot image with forceencrypt disabled. My Nexus 6P should arrive tomorrow and I will start working on decrypt once I get my hands on it.
Team Win Recovery Project 2.x, or twrp2 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Read through that thread. Part of the issue is that I don't know which variant (MDA89D & MDB08K) I have, or how to find that out seeing as I can't boot into the phone.
If I have the variant I may be able to fix this through the unified toolkit (though I'm not sure of that)

Did you ever fix this?

Try flashing the factory image and starting from scratch. You must have messed up somewhere. Re-download the boot.img from Chainfire's thread, maybe that was corrupt or something.

1. Download the MDB08K factory image (it's not a variant, it's a Marshmallow update) and unzip it.
2. Download the MDB08K boot.zip from Chainfire's modified boot.img thread
3. Download latest SuperSU beta zip
Wipe phone in TWRP, to include format data.
In bootloader, fastboot flash MDB08K
fastboot flash modified boot.img (from zip)
In TWRP, ADB sideload SuperSU
Reboot and it should perform normally.

Thank you for your reply, but I can't get into TWRP either!! Any way for me to restore to factory or do the repairs from in flashboot without the restore?

I ran into the same issue last night trying to install TWRP. I'm still not sure how to get around it but I did get my phone back. you should be able to get to the bootloader (hold the power button until phone turns off, then hold vol up+vol down+power) once there use ADB fastboot to go back to stock.
this link will walk you through what you need. follow step 7.
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
here it is as well:
How To Flash The Factory Images (And Return To Stock)
Prerequisites: unlocked bootloader (section 1).
Download the appropriate factory images for your model here.
Unzip the angler-xxxxxx-factory-xxxxxxxx (x's replace variables) into a directory on your PC (for this guide we'll use C:\angler\).
Once unzipped you should have a folder named angler-xxxxxx (x's replace variables). Open it and move the following files to a new directory named C:\angler\images\:
bootloader-angler-angler-01.31.img
radio-angler-angler-01.29.img
(Please note that radio and bootloader naming changes from build to build so the filenames and below commands will change with them)
Within C:\angler\angler-xxxxxx\ you'll see another zip archive named image-angler-xxxxxx, unzip the contents of that zip into the C:\angler\images\ folder we created before. Now within C:\angler\images\ you should have the following files:
android-info.txt
boot.img
bootloader-angler-angler-01.31.img
cache.img
radio-angler-angler-01.29.img
recovery.img
system.img
userdata.img
vendor.img
Boot into the bootloader and connect your phone to your PC via usb cable.
Open a command prompt from within your fastboot folder (navigate to where you have fastboot.exe located on your PC, shift + right click anywhere within that folder, select open command prompt here), enter these commands to flash:
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-01.31.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-m8994f-2.6.28.0.65.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash userdata C:\angler\images\userdata.img
fastboot flash vendor C:\angler\images\vendor.img

Thank you. I was eventually able to do tysonwald's suggestion. First I didn't know what my version was, so I couldn't.
At some point I was able to get into the phone with constant gapp errors, check it.
Now my phone is unlocked and rooted. But when I go to settings to security (and when I tried to set up my fingerprint) settings crashes. Any ideas?
There was still some issue. I wiped the phone with the above method again, did NOT set up twrp/root, and everything works. It was something about the custom boot image I guess. Any advice if I want to try to set it up again?

Problem solved. Needed to update to newer image before doing everything. Issue resolve from Heisenberg's thread. Thank you all!

I had the same damn issue last night. Thise bootleg instructions had me flashing build k boot.img on build D. Maybe i wasnt paying attention lol!

I have a very similar problem, I flashed the k boot img. and now I'm stuck in an endless bootloop any idea?

Read thru this guide and follow the instructions to the T. http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

I had a similar issue just now where my phone got stuck at the TWRP logo. Selecting the reboot option in download mode refused to remove it. I had to follow step 10 to get my phone back to stock. I'm afraid to try this again now

Is there anyway to know which version do i need to download? i bought the phone already bricked and i am trying to bring it back to life

[Q][Help] Nexus 4 stuck in bootloop Recovery after flashing twrp to boot

Hi,
I made this post/thread because i couldn't find a solution to my problem through this forum and google.
Here is my trouble:
I was trying to install a twrp recovery and was following the instructions of a tutorial.
-So first i installed flashify and proceeded to a back up of the current kernel and current recovery
-Then downloaded a custom recovery image through TWRP release for my nexus 4
-After this i accidentally flashed the recovery image to boot instead of recovery
Now as you can guess the trouble is that my phone only boots to TWRP recovery instead of usual boot.
I tried to find aswers on this forum and google and yet i didn't find a solution.
I tried this post but without results:
http://forum.xda-developers.com/tmobile-lg-g3/general/fix-recovery-loop-twrp-computer-t2873386
I would be grateful for any help and wish to recover this mistake without using a factory reset if possible.
Thank you, as you can see i am pretty new to this environment.

Can you get into fastboot mode? If yes, try flashing a stock Google rom and perform a factory wipe after installing the stock rom.

Thank you for your answer, yes i can get into fastboost mode. As i am pretty new can you explain me how i can flash the stock Google rom (i guess it is the factory rom provided ?). Will this operation erase my data on the phone ?

Boot into fastboot and flash boot.img and recovery.img file from stock rom. Make sure you use the stock rom that matches the rom currently installed on your phone.

Once in fastboot, extract the downloaded zip you got from Google. There you will find flash-all.bat Execute it as admin and wait. If it doesn't work, then extract the zip within the first zip and you should get loads of .img files. You will manually have to flash them. The commands are a bit different for each partition. They go like this:
Code:
fastboot flash system system.img
fastboot flash recovery recovery. img
fastboot flash cache cache.img
fastboot flash boot boot.img
fastboot flash data userdata.img
Note that if your cmd/terminal isn't open from the directory where the files are you will have to input it's location, for example
Code:
fastboot flash recovery C:\Users\YOURUSER\Desktop\recovery.img
Also note that there must be no spaces neither in the file name or the directories where the file is located, otherwise it probably won't flash.
Also yes, doing this will completely revert you to stock, and you WILL loose all your data. You could try just reflashing recovery.img and then flashing TWRP over it. If you can get to TWRP after this, then connect the USB cable to your PC and transfer all the data you need, after which I recommend flashing to stock. You can root and/or flash custom ROMs after this.
However in your case I think you don't have to completely go back to stock. Just try flashing the proper boot and recovery images over fastboot like I explained above and try booting then.

Once in fastboot, extract the downloaded zip you got from Google. There you will find flash-all.bat Execute it as admin and wait. If it doesn't work, then extract the zip within the first zip and you should get loads of .img files. You will manually have to flash them. The commands are a bit different for each partition. They go like this:
Code:
fastboot flash system system.img
fastboot flash recovery recovery. img
fastboot flash cache cache.img
fastboot flash boot boot.img
fastboot flash data userdata.img
Note that if your cmd/terminal isn't open from the directory where the files are you will have to input it's location, for example
Code:
fastboot flash recovery C:\Users\YOURUSER\Desktop\recovery.img

Thanks to both of you I managed to fix this just by flashing the boot.img of the Google factory img. It didn't erase my data except my messages which is nice.

Is it possible to root OOS 10.0.1?

lately I did a clean install of OOS 10.0.1 on my International 6t. Installed OOS and magisk from TWRP.
After booting there was a Magisk Manager in applications claiming that Magisk itself was not installed. I tried to install Magisk from Manager, but failed. Then I reboot the phone into the recovery and TWRP was gone!! There was only a stock recovery. Well, I tried to run TWRP from computer with 'fastboot boot .\twrp-3.3.1-28-fajita-Q-mauronofrio.img'. Error - "remote: unknown command".
I searched forum and found a thread fastboot boot twrp.img FAILED (remote: unknown command). @dbarrett480 wrote: 'Twrp can't flash anything to system in A10 right now, so unless that is fixed there is no point at this moment anyway. A10 uses a virtualized system partition which doesn't allow R/W access to system....'. Does it mean that rooting is not possible with stock OOS and only possible solution is to use custom ROM?

It is. Look for the patched boot.img and flash that through fastboot. Make sure to install magisk manager first.

The information you found is outdated. I'm surprised you didn't properly read through the official TWRP thread here, more specifically this post clarifies the error in your use of fastboot (or better said: the use of fastboot according to the mistakes made by OnePlus). Which is also mentioned several times in the page you linked to.
As a senior member, please don't create new threads inquiring information you could easily find. Even though the methods to obtain it have been challenging for a short while, being able to achieve root has never been interrupted for this device. Even without being able to modify system files. Systemless rules!

So, should do following:
Install Magisk Manager
Flash patched boot.img through fastboot
Install TWRP
Install Magisk
Is it correct?

The patched boot.img already contains magisk.
But you don't need twrp to be rooted, unless you really want to use it for something else... But i don't use it anymore. So I'm fully stock, except that I'm unlocked and rooted.
So it should be:
1. Install magisk manager.
2. Flash boot.img
3. Enjoy. But check magisk manager if it was successful.

Regarding all that was said here, is rooting possible by following these steps?
Reboot
Fastboot TWRP img
Use volume up to recovery and power button to boot to recovery
Flash 10.0.1 stock boot img from TWRP
Flash TWRP zip
Reboot to recovery
Flash Magisk 20.1
Flash kernel if want
Reboot system

That's only if you need TWRP.
But for what I've been reading, you don't need TWRP and then i suggest to not install it.
Just flash everything stock and keep it that way. Only thing to flash is the patched boot.img with root in it.
You can always update Android from the settings and patch/install boot with magisk manager on inactive slot. This will keep your device rooted without the need of TWRP.

Here what I found:
https://forum.xda-developers.com/showpost.php?p=81111389&postcount=145
Today I installed the new update, 10.0.1 for OP 6T and then I discovered that there is no magisk patched boot.img yet. I extracted it with payload dumper, patched with the installed magisk and flashed successfully.
I uploaded it to my drive for others. https://drive.google.com/open?id=1kb...VgWNaWgLN6j17b
The commands for flashing are:
fastboot flash boot_a magisk_patched.img
fastboot flash boot_b magisk_patched.img
Maybe someone can add it to the first post.

I used this method to root 10.0.01
https://forum.xda-developers.com/oneplus-6t/how-to/ultimateguide-t4004367
I went from rooted 9.0.17 to 10 to 10.0.01
Never had an issue and everything works fine for me.

I still don't get why people don't use the good old way:
fastboot flash boot twrp.img (latest version)
If you just need root use twrp to flash Magisk zip
If you need twrp flash twrp installer also
Reboot
All the mess before was because we didn't have a working TWRP! Now that we have it don't need to use patched boot img made by others.
