[Question] Z799VL

Hello, everybody. My phone is a ZTE Majesty Pro LTE [Z799VL] from TracFone/Straight Talk. The phone runs Android 6.0.1 and has USB Debugging and OEM Unlocker activated. I have been trying to find a way to root this phone and I'm left with more questions than answers. The two most nagging questions are as followed:

1. Is it possible to access to fastboot/bootloader? Is this a ZTE or TracFone problem? ADB just reboots my phone and the only mode I can activate is Recovery Mode.

2. Is it even possible to root this phone? The impression I get is that ZTE phones are hard to root. I tried looking into making a TWRP recovery, but as a novice and lifelong windows user, it will take a lot of time before I can figure out at what I'm looking.

Thank you for your time.

    Hi, I have the same phone from Straight talk, according to the paperwork supplied with the phone it's "Locked" and "Unrootable" but I think that's like saying "Unhackable" , "Unsinkable" or "Unbreakable" it's just a matter of time and effort. I've been playing around with rooting it for a couple of days, "without success" this morning I found a tweet from SRS ROOT

    "#SRSRoot: ZTE Z799VL (Build: Z799VLV1.0.0B05) #Android  6.0.1 Now Supported for #Root at (link: http://www.SRSRoot.com) SRSRoot.com6:48 AM · May 30, 2017"

    I haven't tried it yet but I downloaded there software and plan to give it a shot soon.

    FWIW, the link in the post for SRS doesn't work properly due to forum messages being reformatted. Just type the URL manually, and search their site.

    The footer of the SRS website says: "Professional GSM Unlock Solutions", not sure if this might be a problem for CDMA devices.

    And, finally, the SRS software is for Windows only, no support for Mac, no support for Linux, is not a browser application.

    Don't take me wrong, I'd love such a solution, and if I had Windows, I'd try this. Wish I had learned about this site 2 weeks ago, before I ditched my Galaxy S5 which got supremely borked by Verizon updates.

    I'm a Linux user myself and haven't had any luck running the SRS software with wine or virtual box, that's why I haven't been back to confirm if it works, I have also been reading all over about these phones from straight talk and now have serious doubts that it would work. As I understand it straight talk had ZTE lock the bootloader making there phones unrootable. It might work for a z799vl phone but not one from straight talk. It's a bummer but my phone will be occupying a landfill soon and I'll be getting a phone from a different service provider, I've had nothing but problems with straight talk anyway.

  • Quick note on my pursuit for a root method on this phone;
    I have attempted to use the SRS Root tool described and it failed. I tried several times, on two computers. I also ran through KingoRoot and KingRoot a number of times in hopes there was a slim chance it would work. Again, no success.

    I'm now searching for the stock Firmware of this device with no such luck either.

    Half the reason for me too root my phone was to remove some bloatware and free up some internal memory, since memory is so limited on this phone.

    I've since switched to plan B until a rooting option is found, I formated an SD card as internal memory. It's a menu option that comes with Marshmallow but ZTE removed it from these phones. WTF? ZTE
    So I had to use adb.

    Anyone interested in using your sd card as internal memory can web search. " Format sd as internal " and you'll find several tutorials. I had trouble installing the drivers for the phone, that hung me up for a while but eventually I figured it out. Now I have GB's of extra memory for installing apps. It's not as good as having Root access but it's better than nothing.

  • Try kingroot or Kongo root you would have to look up the apk... I'm not promising anything.

  • http://www.srsroot.com/ con este proceso si se hace el root el equipo, acabo de terminar de hacerlo

  • SRSRoot appears to have a Bitcoin miner attached to it's installation. DO NOT USE IT. Fake details on display. I don't Trust it. Anti-virus used= Iobit Systemcare Ultimate.

    One last chance, download google account manager.apk, and quick shortcut maker.apk in a flash drive, plug in the ZTE phone with a cable charger. Note: the cable must be the one that has a USP cord on it. After you plug in the USP in that thing, you will see the pop up screen for the option. Then click on the file explorer and keep going to where you save the apk apps at, then run it from there...SOoo simple as that.. I never done it, but I'm trying to think of some ways of running the apps from the external instead of keep searching for the setting/doors. Always remember. If the doors of the house is lock, then use the windows. If both are lock, then use the ceiling. And if all of them aren't work. Then use a big 🔨 to break through the wall.

    Hi everyone, Mexirony here, first-time writer, long-time reader. I haven't been able to find a viable method to root the ZTE Majesty Pro (Z799VL) neither the ZTE Majesty Pro Plus (Z899VL). Factory-locked fastboot seems to be the eternal source of the problem. Decided to share with you guys a quick manual I made for the occasion to, at least, be able to debloat the device and make it run smoothly, while a smart soul of yours finds out a viable root technique. The method is valid for both devices and it is supported in long extent by the app "Ice Box". It is also valid only for Android 5+ or higher. If you got Android 4- or lower you may want to use Debloater instead.

    NOTE*: I'm not responsible for soft-bricking the device if you don't follow to the word the instructions provided and educate yourself in the overall competences and crafts of Android services. If by mistake you fall in soft-bricking, simply do a hard reset, wipe data to factory settings and start all over again from the scratch. In that case, review this link

    0.- VERY IMPORTANT: Backup all your data, contacts, phone numbers, calendar, agenda, photos, videos, bookmarks, notes, Whatsapp media, Facebook downloads, useful cache, personal information, etc., etc., all out from your handheld device.

    1.- Install "Minimal ADB And Fastboot" software in your PC from here.

    2.- Install "Ice Box Pro" - not free but the pro - version in your smartphone, either directly from Google Play ($1.99) or download somewhere in the Internet searching the criteria "ice box apk download". Navigate to "Settings -> Security". Check the option "Unknown sources". Tap "OK" on the prompt message, then select "Trust".

    3.- Activate "Settings -> Developer options -> USB debugging" in Android Settings. If you don't know how to launch the "Developer" tab read this.

    4.- Go to "Settings -> Accounts", then remove ALL ACCOUNTS including your Google, Skype, Hotmail, Netflix, Facebook, etc., etc. Later on you will set back on track all your personal accounts to normal.

    5.- Multi-user or guest mode needs to be dismissed as well if has been set on your device (typically not the case). Check the status in "Settings -> Security -> Device Administrators".

    6.- Connect your phone to your PC via USB-micro-USB cable. Make sure you have the USB drivers of the cellphone properly installed in your PC for Windows to recognize the dispositive. If not the case, download Android USB drivers here and try again.

    8.- Run the "Minimal ADB and Fastboot" application previously installed in your Windows PC. You will access to the command window (dark background) for scripting.

    8.1.- Type "adb devices" to check if your device is recognized. If that's the case, an alpha-numerical code will appear signaling your phone is successfully identified by Windows and ADB. For example:

    C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
    List of devices attached
    32F476848526 device

    If you don't see the alpha-numerical identification number, stop. Reinstall drivers again until the system plentifully recognizes the smartphone. In Windows, go to "Control Panel -> Device Manager" and verify the dispositive is identified not only as a "Portable Device" but also as an "ADB Interfece". For more information go here.

    8.2.- Type now the following command in a single line (copy and paste if wanted):

    "adb shell dpm set-device-owner com.catchingnow.icebox/.receiver.DPMReceiver" (remove exclamation marks)

    At this point in time, "Ice Box Pro" must have been installed in the phone for this code to take effect. A statement will appear in the command line confirming the script assignation on your device. If you got an error, make sure all your Android accounts are dismissed, that is a mandatory sub-step.

    9.- Reboot your phone then add your accounts back again as usual.

    10.- Run "Ice Box" and select, finally, configuration as "Local Administrator". Now you have grants to freeze apps and services at will, just as if you were vividly rooted.

    11.- Get now rid of all bloatware and useless services (about 95% of all active script load). In "Ice Box", go to "System" tab, then in local "Settings" (three vertical dots) check "Include Hidden". You will see now the full list of apps and services in use. Freeze the freaking list out! That is what makes the phone performing like garbage! Just make sure you have the following critical services active (not frozen) at all times in order to prevent soft bricking:

    (1) Google Account Manager,
    (2) Google Keyboard,
    (3) Google Services Framework,
    (4) Media Storage,
    (5) Package Installer,
    (6) Android Launcher (active by default if you don't see this one in the list)

    The rest can be safely disabled (frozen) without the risk of boot looping. Those are the very bare minimum required services for minimal operation, though. If you want, for example, telephony service enhanced, you will need also to activate (a) Data Service, (b) Dialer, (c) Contacts, (d) Contacts Storage, (e) Messages, (f) MmsService, (g) Phone and Messaging Storage, and (h) Phone Services. If you want, lets say, GPS enhanced, you will then need to activate Fused Location service as well. If you want to connect to your PC you'll need MTP Host active. If you want to run Google Play and download apps, you will need (a) Downloads, (b) Google Play Services, (c) Package Access Helper and (d) Package Installer, and so on and so forth for other tasks and duties. Get familiar with all service functionalities so you become skillful to know which ones to turn on and which ones turn off at any given time at any given task. Rule of thumb: the minimal the services active the fastest the system becomes. Both "Google Play" and "Google Play Services" play a major, I repeat, a major role in draining the battery - along with the LED brightness - , so try to keep them both at bay by freezing them as much as possible.

    12.- Enjoy!
