How to Root without flashing custom recovery

HOW TO ROOT YOUR DEVICE WITHOUT FLASHING RECOVERY
This can be done with two methods.
ADB or FASTBOOT.
I have tested both methods and they worked for me.
I tested this on JSS15J. I am not sure about any other versions but I guess it should work.
SOME BASIC INFORMATION
Usually when you want to root your device, you must have UNLOCKED BOOTLOADER.
A CUSTOM RECOVERY is usually used to flash SuperSU to gain root access.
CUSTOM RECOVERIES ARE USUALLY FLASHED (they permanently replace your stock recovery)
In this guide, You BOOT into custom recovery by going into BOOTLOADER and then using fastboot/adb tools to flash SuperSU .
Booting is temporary and thus once you restart from recovery, the custom recovery will be gone
Make sure, you have USB debugging mode enabled. To go into bootloader you can either use adb commands ( Type [adb reboot bootloader] in cmd in platform tools directory with your device connected) or do it manually by turning it off and then holding power and volume down.
You must also have platform tools of SDK (Fastboot and ADB) for this to work. MAKE SURE YOU OPEN CMD into the folder where platform tools are present.
Try it on OWN risk. I will not be responsible for bricked devices or any damage.
ADB METHOD
Connect to your PC and make sure USB debugging is on.
COMMANDS IN BRACKETS. DON'T WRITE THEM. COMMAND WOULD BE LIKE : fastboot boot recovery.img
MAKE SURE YOUR DEVICE HAS UNLOCKED BOOTLOADER
(fastboot boot [recovery.img])--------------------- Name of recovery to be here
Mount /system and push the necessary files once the recovery has started:
(adb push su /system/xbin)
(adb push Superuser.apk /system/app)
Set correct permissions:
(adb shell)------------------------------ You have got into your device's shell
(chmod 06755 /system/xbin/su)
(chmod 0644 /system/app/SuperSU.apk)
(exit)
Reboot:
(adb reboot)
FASTBOOT METHOD
This is relatively easier as you will boot into custom recovery temporarily and then flash ZIP of SuperSU. Afterwards I recommend to clear davik cache and restart.
UNLOCKED BOOTLOADER REQUIRED
Boot into bootloader.
Type these commands to boot into custom recovery. This will not flash recovery and you will have stock recovery once you restart.
fastboot boot recovery recovery.img where recovery.img will be the file name of recovery
(After 4.4, use this command "fastboot boot recovery.img" instead of above mentioned)
After booting into reccovery, flash SuperSU and you are done.
I recommend clearing dalvik cache before leaving and restart.
And you are done.
YOU CAN ALSO USE A PREROOTED KERNEL WHICH YOU CAN FLASH VIA FASTBOOT. I AM NOT SURE IF THERE IS ANY
For information on how to retain root after OTA, please refer to this :
Update Super SU is also taken from this guide.

If you are stuck in a bootloop, make sure you have cleared dalvik cache in custom recovery.
I got bootloop when i tried with fastboot method as I was new to twrp, I explored it a bit and tried to remove system and tried overwriting data to see how it is different from CWM and check its strength. I got an error clearing cache so I rebooted into custom recovery to clear dalvik and my nexus booted fine (DON'T TRY THIS, JUST CLEAR CACHE AND WIPE DATA and restart)
REMEMBER, UNLOCKING BOOTLOADER WILL DELETE ALL YOUR DATA AND DOING WIPES WILL ALSO DELETE ALL YOUR DATA.
DALVIK WON'T DELETE YOUR DATA BUT
MAKE SURE YOU HAVE MADE A BACKUP using BACKUP PRO (non rooted) or Helium (non rooted) and Titanium Backup Pro (Daah, you are not rooted so this won't work)
GOOD LUCK

Booting into custom recovery to install root works fine.
As you mentioned unlocking bootloader is still a prerequisite.
You may want to just use the SuperSU install zip though. Though I haven't tried Superuser on this tablet, it is my understanding it hasn't been modified to work with 4.3 security. That may have changed since I last looked so if you find differently please post. SuperSU added a daemon mode to deal with 4.3 security changes.

I got bootloop but then realised it might due to trying to wipe system in twrp. Clearing dalvik worked fine .SuperSU used

So you don't replace stock recovery if you boot into a custom recovery using fastboot?

The trick here is to BOOT into custom recovery BUT not FLASH recovery permanently. Once you restart, the CUSTOM recovery will be gone.
You can use simple commands if using Fastboot
fastboot boot recovery [recovery name.img]
This way you will install SuperSU using recovery which is relatively easier than ADB commands.
You will only go into recovery temporarily.
I also read a forum where you can preserver root even after OTA/ Updates.
[UPDATE]
http://forum.xda-developers.com/showthread.php?t=2415497
Do check that out as well.
I tried this with Twrp and superSU.
I got bootloop as I have been always CWM person so I accidently tried to delete system too with dalvik cache and hard reset and I got an error
However, I boot again into recovery and cleared wipes and the bootloop was gone

You restart your device. Boot into bootloader and use fastboot to Boot into custom recovery(command given in post above).Once Into recovery, you can easily clear dalvik cache.
And remember, it might not require clearing cache because I was exploring twrp n overwriting data n tried To delete system to see how powerful the recovery is. I will update guide now

The "fastboot boot recovery recovery.img" command is not working anymore. The command prompt returns with a "cannot load recovery" error. At least that's what it does on my Nexus 7 running Android 4.4.2.
This seems to affect Android 4.3 and upwards according to this Nexus 4 thread: http://forum.xda-developers.com/nexus-4/help/solved-fastboot-boot-recovery-img-t2380675
There's a workaround with a different fastboot command line as mentioned in the thread. I wonder if there's also a fix for the Nexus 7. Any replies would be greatly appreciated.

Do you have TWRP installed? If so try a restore of my B27 system image + Boot + signed TWRP
Check this thread http://forum.xda-developers.com/axon-7/help/update-axon-7-a2017u-build-27-t3464517 it's post 51, if you are willing to test. Usual disclaimers apply.
Ignore that, since all my backup has is the system and boot partitions it's missing some of the firmware. The best method hands down is to flash the stock B20 system image

What do I do if TWRP asks for a password?

I noticed that as well, TWRP wanted a password when I went in to it to decrypt the data partition, something I haven't seen before (note that I saw this before I tried flashing anything recently, I just went in to make a full backup first.) I tried using my phone lock pin number, no use. I tried "default_password" as well as google suggested but that also didn't work. /shrug , bedtime here, will work on it tomorrow.

[A2017U - B29] "Fastboot Flashing Unlock" returns "Unknown Command" in ADB

[A2017U - B29] "Fastboot Flashing Unlock" returns "Unknown Command" in ADB
Hi !
Quick info: I am not a novice when it comes to rooting / unlocking bootloader / installing TWRP or CWM / installing Xposed Frameworks, etc
I will make this short and sweet.
My Info :
- Axon 7 Gold - A2107U (US variant) with Update B29 installed (A2017UV1.0.0B29)
- Minimal ADB and Fastboot
- Windows 7 x64 Home premium
Here are the steps I have done:
1-
I installed the ADB drivers and Qualcomm WWAN drivers on my computer.
2-
Under Developers settings, I have enabled "OEM Unlocking".
3-
Using Axon7backup.exe, I created 2 backup files: "stock_recovery_backup.img" and "stock_boot_backup.img"
4-
Rebooted in bootloader using "adb reboot bootloader", (my device was listed). I first tried "fastboot oem unlock" then tried "fastboot flashing unlock", both returning "Unknown Command".
HERE IS WHERE I AM CONFUSED:
Normally, anyone would Unlock to bootloader THEN install TWRP, but from what I've seen with Axon7, some people say that Installing TWRP is "required" to unlock the bootloader.
I've seen some say that they have successfully rooted / unlocked bootloader with the B29 update, but I don't see any zip files or threads for the B29.
Could anyone enlighten me on the steps that I (and many others) have to do in order to Unlock the Bootloader and be able to install TWRP and Xposed Framework (and root).
Thank you !

Ok so the long story short is that the bootloader is not unlockable out of the box. When ZTE released the bootloader unlock, they released a separate ota for it called B20_boot from B20 which modified the fastboot image. It didn't make sense for a lot of people for ZTE to release a separate OTA since it would not allow them to recieve future otas (such as B29) so they are working on a new bootloader unlock. So since you are on B29 and the bootloader is not unlockable out of the box and you cannot update to B20_boot since you are not on B20 this is what you do:
1) I am assuming you already have the tool downloaded since you used it to create the backup files so just follow the same instructions to boot into edl mode, then open a command window where the tool is located. Then execute:
Code:
axon7backup.exe
to start the tool and then
Code:
axon7root.exe -p # -r
where # is your COM Port # in Device Manager. The tool will flash the signed version of TWRP with ZTE's signature from the leaked firehose onto your Axon 7.
2)Hold down volume up and power to exit download mode and boot into recovery which should now be TWRP.
3) Download the bootloader unlock zip from @DrakenFX: https://www.androidfilehost.com/?fid=529152257862665656. Flashing the zip will replace your fastboot image with the one from B20_boot.
4) After you have flashed the zip, reboot to bootloader and just execute
Code:
fastboot oem unlock
and you are good to go!

^^The stock fastboot does not support the unlocking command. There's another fastboot image in the bootloader unlock thread that gets flashed first. *THEN* you can issue the unlock command.
I've been messing with android at least since late 2009 and have seen many variants of unlocking processes. This one is new for me too.

I was wondering, if I backup my DATA only using TWRP and restore them after doing "fastboot oem unlock", will I be able to get my apps back without breaking my system ?
EDIT: After doing "Fastboot oem unlock", TWRP gives me "Mount: Decrypt Data: Enter Password:"...
EDIT2: Ok now Android is locked... it's asking me to enter a password *NEVER MIND- FORMATED CELL, NOW WORKS*

Did you just flash TWRP using -r or flashed the boot image as well using -b? Because if you just flashed TWRP the data decryption thing should not have happened. For some reason ZTE screwed up encryption to the point where if you backup data in TWRP with a pin/password/pattern enabled and then restore from it you will get a data decryption prompt where no password would work, not even your own. If you get this you have no choice but to wipe your data and then do either a Google restore during setup or use Titanium Backup(after you flash SuperSU) if you have it. In the future if you want to backup your data and until ZTE fixes it, you have to disable your pin/password/pattern first.

The modified boot image allows people without an unlocked bootloader to have root however if your bootloader is unlocked you should not do it as you will have the data decryption issue.

Flashable Recovery?

Hello, I know our great device does not have a recovery partition, so we need to use fastboot to boot TWRP. But muy question is, is there no way to boot into TWRP without a computer? Maybe a terminal command from Android itself, or a little script that we can run when needed? This might be a noob question, but I'm sure many here could profit from a positive answer.
Thanks

Assuming youre rooted... Ive used the reboot app on my phone. I have a 1926-7 Moto G6 Plus. It will boot to fastboot, fast reboot, recovery, reboot system etc. Look around xda and see if someone has a good reboot app or else use GP. I actually had twrp flashed permanently to my phone but it would not back up so I have to redo it. Also the phones data was encrypted and I didnt know how to fix it. I hope that you are able to find something that works for you

You can boot into TWRP via terminal command without using a computer. Use the 'dd' command ( 'dd if=/dev/block/bootdevice/by-name/boot of=/sdcard/boot.backup.img' ) to take a backup of your boot.img. Than use 'dd' to overwrite boot with twrp and reboot to recovery (dd if=/sdcard/twrp.img of=/dev/block/bootdevice/by-name/boot)
Later to boot your phone as normal you only have to install your boot.img backup via TWRP.

now we can install a TWRP 3.3.0 ONLY ON DECRYPTED ROMS (the lastest Havoc, Resurrection Remix, AEX, Decendant, PixyOS are unencripted by default) for flashing magisk modules or mods but it will be overwrite when we flash/update our custom/stock rom:
https://drive.google.com/open?id=1CqzvBiEfk9xucXG8UemNZMhBxDCeSV0i
How to install it:
Put the donwloaded TWRP on your plataform tools folder and in your internal/sd storage.
Boot the same TWRP (fastboot boot TWRP.img)
Go to ADVANCED and select Install Ramdisk Recovery
Check backup boot box( in case something goes wrong just restore your boot partition)
Swipe and wait until finish.
Reboot
If every reboot finishes in twrp booting just flash magisk and youll be able to boot into system.

[GUIDE] Flashing ROMs with TWRP black screen

Hello,
Many people report, that their TWRP/PBRP is black and they can't install custom ROM or flash stock ROM by recovery.
Problem occurs in devices with Jdi display.
It is recommended to flash Oreo, then recovery work, but if you want use Android Pie you must be on this stock firmware (I tried Oreo and flash Havoc (Pie) = bootloop).
We need:
Unlocked bootloader
Turned on android debugging
ADB (minimum 1.4.3)
TWRP/PBRP (.img file)
ROM, GAPPS,...
YOUR DATA/PHOTOS/DOWNLOADS WILL BE REMOVED, SO MAKE A BACKUP!
Let's get started:
1. FLASHING ROM
/the phone is on/
1. Use cmd and type: adb reboot-bootloader
<phone will turn on in fastboot mode>
2. Type: fastboot set_active b
Then: fastboot boot <your_recovery.img>, e.g. fastboot boot twrp.img
<phone will reboot, the screen will be black>
<wait to Windows new device sound>
3. Type: adb shell
twrp wipe cache
twrp wipe dalvik
twrp wipe system
twrp wipe data <- NOW YOUR DATA WILL BE REMOVED, SO MAKE A BACKUP BEFORE!
twrp sideload
adb sideload <location_of_your_ROM.zip>, e.g. adb sideload C:\Havoc.zip
When the installation is completed you will see "Total xfer X.XXx".
2. FLASHING GAPPS
Now: adb reboot-bootloader
<phone will turn on in fastboot mode>
fastboot set_active a
fastboot boot <your_recovery.img>, e.g. fastboot boot twrp.img
<phone will reboot, the screen will be black>
<wait to Windows new device sound>
adb shell
twrp wipe cache
twrp wipe dalvik
twrp sideload
adb sideload <location_of_your_GApps.zip>, e.g. adb sideload C:\GApps.zip
When the installation is completed you will see "Total xfer X.XXx".
3. FLASHING PATCHED BOOT IMAGE (MAGISK + ROOT)
adb reboot-bootloader
fastboot flash boot <your_patched_boot.img>, e.g. fastboot flash patched_boot.img
fastboot reboot
<phone will start, the first start may take some time>
It's instruction for performing these three steps sequentially.
System will be installed on slot B, the Gapps and patched boot on slot A.
Now you can enjoy custom ROM

3. FLASHING PATCHED BOOT IMAGE (MAGISK + ROOT)
adb reboot-bootloader
fastboot flash boot <your_patched_boot.img>, e.g. fastboot flash patched_boot.img
fastboot reboot
<phone will start, the first start may take some time>
It's instruction for performing these three steps sequentially.
System will be installed on slot B, the Gapps and patched boot on slot A.
Now you can enjoy custom ROM

The data partition is encrypted. If you want to access this partition you have to format it by TWRP. When you start system with forced encryption, the data will be again encrypted (or use custom ROM without encryption or install script to disable it on stock software).

I had a similar problem while using twrp to copy files to the phone storage, try this command before doing anything:
fastboot -w
Note: This wipes all data.
This made the phone storage accessible.

Hello! How do I know if my device has a Jdi display panel? If it does have, do I need to follow this guide every time I flash or update a rom?

Try to boot TWRP on Pie, if you see TWRP GUI mean you don't have Jdi display. You don't have to flash anything, only boot by fastboot.
It depends of your ROM and system updater, I follow the guide to flash new version and all is working ok.

I think my display is tianman (ss atached). Is that right? Do you know if any display is affected with burning effect? It's just that I had a RN5 and I changed from MIUI to a custom ROM and one day the display just got the burning effect
Thanks for your reply.

I'm getting the same error when doing fastboot -w, and the ROM I flashed (Resurrection Remix) is stuck on startup splash screen.
Any idea what can cause this, and how I can recover?

Thanks! Now I could install Havoc and have access to my files!
Op you should include ,,fastboot -w" in your guide.

Finally i can boot PitchBlack recovery without Blackscreen in JDI panels::
Boot this recovery file: https://sourceforge.net/projects/pitchblack-twrp/files/jasmine_sprout/
Only one difference between the guide of this Thread....
I can´t change the partitions in PitchBlack recovery... i used the command in the op to change the partitions.... NOW i can flashed the Resurection remix rom in my phone

So, I was able to recover from this by using Xiaomi Flash Tool (v20170425) to flash the V10.0.7.0 stock rom. That got me back to a working stock Android.
I then retried the steps from this guide (except Gapps and patched boot), and this time I was able to get my Resurrection Remix started. However, the userdata file structure looks like rubbish, and none of the apps can write to or read from it. I tried to do a factory reset (from within custom rom) to fix this, but then the phone turned off and would not boot to custom rom again. fastboot -w still doesn't work.
Any ideas how to make the userdata partition great again?

I made it work by doing the first 2 steps from the OP and then after booting into system the first time I booted into bootloader and then used fastboot -w. I did this with Havoc OS though so it might not work for everyone.
When I wanted root and didn't know how to get a patched boot image for my ROM, I just followed the steps to access TWRP through ADB again and then wiped cache and dalvik, afterwards I used the sideload command to flash Magisk on my phone.

I eventually figured out that all my problems occurred because I was using old versions of ADB and fastboot. After updating to latest platform-tools (currently r28.0.2) I was able to run fastboot -w without problems. And once that worked I was able to set up a fully working system following the steps of this guide.
Thanks for a very useful guide, it saved my day!

I'm not entirely sure I understand your question, but please note that by following the OP instructions you never flash TWRP, you just boot right into it from RAM. So should be no problem to do that while keeping stock ROM.
