[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 !

Thank you ![/QUOTE]

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:

axon7backup.exe

to start the tool and then

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 [MENTION=3044858]DrakenFX[/MENTION]: 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

fastboot oem unlock

and you are good to go!
[ZTE Axon 7 Questions & Answers] gpz1100:
^^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.

"Uploaded By: tenfar

Uploaded On: 2016-09-19 23:10:07"

Should I use the B27 or follow the B20 method ?

EDIT: Should I do following command ?: reboot disemmcwp (to remove protect write, or it's no longer necessary? )
[ZTE Axon 7 Questions & Answers] bkores:
I edited my original answer. Since you already have axon7backup.exe you don't have to download the tool. And yes you should do "reboot disemmcwp" if you want to be able to make changes to /system
[ZTE Axon 7 Questions & Answers] Boutchoo:
Nice ! TWRP is now installed !

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*

Edit3: Do I need to flash SuperSU or is it pre-packaged ?
[ZTE Axon 7 Questions & Answers] bkores:
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.
[ZTE Axon 7 Questions & Answers] Boutchoo:
I copy pasted your line "axon7root.exe -p 8 -r" only, did nothing else.

Also, do I need to flash SuperSU for the root or is it pre-packaged ?
[ZTE Axon 7 Questions & Answers] bkores:
Flash SuperSU
[ZTE Axon 7 Questions & Answers] Boutchoo:
When I flash SuperSU-v2.78-201609011115.zip from my SD Card, it crashes TWRP.
[ZTE Axon 7 Questions & Answers] bkores:
You need SuperSU v2.65 as any other version will crash TWRP(no one knows why)
[ZTE Axon 7 Questions & Answers] Boutchoo:
Ah, I see. It's weird !

Also, what does flashing the boot (-b) does with the Axon 7 ? It's weird that only recovery (-r) is necessary.
[ZTE Axon 7 Questions & Answers] bkores:
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.

Dear All

I am not able to access phone internal storage and SD card of my phone from my laptop (Windows 8.1), after downgrading my Lenovo k4 note from MM to LP (A7010a48_S152_160302_ROW).

USB computer connection options of my phone when I am

1) connecting to Media device then -> it is showing CD drive of Lenovo suite, not able to see both internal and external storage in laptop

2) connecting to Camera (PTP) then -> laptop showing DCIM folder and another pic folder of both internal and external storage, but I can transfer only pics & video, still not able to see both storages.

I am not able to see both storages Int & SD card but able to see both internal and external storage of my phone to other PC like windows 7. But it is not visible on my laptop which is running on win 8.1. Earlier on LP version, I am able to see both storages on my PC.

I had not formatted my SD card at the time of downgrading to LP and removed sd card before downgrading may be it is the problem but other PC both storage are visible, then I tried again to downgrade again after formatting SD card, but did not get success.

Nothing happened when I was retrying to downgrade again LP version updated device, flash tool screen freeze when I clicked download button (I have chosen Firm ware upgrade and Download only both options. I have checked the logs please provide solutions.

[Disclaimer]

I am not responsible for bricked devices, lost data, spillt milk, etc. Backup, Backup, Backup, Using the "Complete Data Reset" feature of the TPtoolbox or the "Erase USB drive" from WebOS, will delete absolutely everything on your HP TouchPad! So you will want to make sure you have your personal data files(music, pictures, videos, etc.) backed up on your computer. Don't forget to move your Nandroid backups onto your PC. By default CWM/TWRP backups are located in SDcard/clockworkmod/backup or SDcard/TWRP/backup .

Note: Make sure your tablet is fully charged before starting any install procedure on the HP TouchPad. Running out of batteries during an install will ruin the process and possibly damage the device.

Thank you, Roland. You always do a wonderful job on your tutorials. I wouldn't use anyone else's. I have a question. There is what is called a "Virtual USB drive" detected. When I tap on it, it asks if I want to use it as a portable storage or internal storage. Which should I choose?
[TouchPad Q&A, Help & Troubleshooting] RolandDeschain79:
I would use the portable storage option

Hey thanks so much:highfive: The media partition is being read as an SDcard, nothing is on there but the ttinstall folder and possibly WebOS. I'd choose portable storage to keep it acting like an SDcard. Setting it to internal storage might reformat it and make it harder for the toolbox to find. I did the internal storage option on my phone and the SDcard came up as internal storage but I lost a bit of total space and wasn't able to separate it easily. You can adjust this on the tablet from settings/storage settings/. Update: I've heard some reports of WebOS not booting when it's set to internal storage, thanks:cowboy:

It crashes when you to try to open the clock app too. If you need to use the clock for an alarm or what have you get another free Clock from the play store. Any other clock app works fine, I believe its been posted about in the Evervolv Nougat thread but it still seems to happen. I expect it will get fixed sooner or later but its probably a low priority.

Hi, happy holidays and new year to you and yours, thanks:highfive:. I don't have a tutorial for that myself but I Googled it here. There was some info however I don't know if any of this will work anymore now that the WebOS servers have shutdown completely, I do have a video talking about that below. If you follow step 2 you shouldn't have a problem with WebOS as its on a different partition and installing android won't affect it, so long as you don't do a complete data reset(step5).

Edit: Checkout post #14 in this thread here Seems to be the best WebOS back up and restore info I've seen. Also interesting info about a data base you can download 6000+ WebOS apps from(here) now that they're considered abandonware.

Day two update: all is still working great. Thank you so much for creating this forum. I thought it would be helpful to list the issues I have to check if other people have the same or if I have found new problems.

[I am running the 26-12-2016 nightly build]

- Only the back (triangle) button works. The square and circle do nothing.

- Gmail app wont sync emails

- If you Restart the tablet it continually loops in a restart cycle (i.e. you cannot use it). Solution I have found is to shut down only.

- Clock app doesn't work, I have disabled the app and don't get the message anymore.

Otherwise everything is working, I have BBC iPlayer on it, Plants Vs Zombies, VPlayer, Sling Kong. Great! My Dad was going to get rid of this tablet but now it is repurposed for my kids (to play games, watch TV programmes on long car journeys) etc.
