BLU Life One X (2016) - How To Root and Install Viper4Android


I am creating this thread for people like me who have been searching for a while for an exact, concise way to root the BLU Life One X (2016) which is available on Amazon. I have had to piece together information from various sources as well as helpful people on XDA such as manos78, yrude and rogersa2k.

Model Number: BLU Life One X
Build Number: ALPS.L1.MP3.V2.21_6753.65U.G_P11
Custom Build Version: BLU_L0070UU_V12_GENERIC 09-11-2015 18:44

This phone is similar in build to the Wiko Fever and Micromax Canvas 5 E481 so a modded Wiko Recovery is used in Fastboot to help establish root. But first the bootloader must be unlocked.

On your PC, you need to have ADB Fastboot files in order to use these commands so I'd recommend downloading Minimal ADB Fastboot. You can get that from here:

Install Minimal ADB Fastboot on your computer, preferably on your desktop so it's easily accessible. 

Next download the CWM recovery file from here (you can also use TWRP, but for this particular instance I chose CWM so that's what I'll provide a link to. I don't like giving instructions for things I didn't actually do myself.):

Unzip the file and place the recovery-custom-wiko-fever.img in the Minimal ADB Fastboot folder you placed on your desktop. Now hold the SHIFT key + right-click inside this folder and choose the option “Open command window here.” A CMD window should appear. Leave this open and set it aside for now.

We first need to unlock the bootloader and since the unlock process will delete all of the files on your phone, it's recommended to perform this before you even login and download apps and settings, etc. 

Once gaining access to your BLU Life One X, go to Settings > About device and touch Build number 7 times to enable Developer options within the Settings. Back out of this area and go into the Developer options that you just enabled and turn On USB debugging and OEM unlocking

Now plug your device into your computer via the USB cable and wait for the device to show up under Computer by pressing the Windows + E keys. Open the device in this window and leave it at the screen where it initially shows all of the phone's folders.

Download SuperSU from here:

Place this zip file into your phone's folder that you opened up previously.

Power Off your device but keep it plugged into your computer.


Power On the device into the bootloader by simultaneously holding the Volume Up + Power buttons until you see the BLU splash screen, then let them both go. 

In the CMD window on your computer, type: fastboot oem unlock and press the ENTER key.

On your phone, select YES with the Volume button to scroll and the Power button to execute it. Then select the option to reboot the phone. This erases all of the info on your device like a Factory Restore. Two reboots are automatically performed and the bootloader will be unlocked.

If you want to check and see if the bootloader is actually unlocked with the CMD window, enter: fastboot getvar all.


Now you need to flash the custom recovery you downloaded earlier. Ensure that you still have your device hooked to your computer via USB cable and make sure the CMD window to that folder is open. 

Reboot your phone into bootloader mode by simultaneously holding the Volume Up + Power buttons until you see the BLU splash screen and then let them both go. Use the Volume Down button to select “bootloader” in the menu and press Volume Up to select it.

Within your CMD window, type: fastboot flash recovery recovery-custom-wiko-fever.img
(After you type "recovery" a second time, you can press the TAB key and it will fill in the rest of the filename.) Now press ENTER.

After the recovery has been successfully installed, unplug the USB cable from your phone.

Hold the Volume Up + Power buttons simultaneously until the phone shuts off then let go of both buttons. Wait a second and hold both of the buttons again until you see the BLU splash screen, then let go of both buttons. This will now boot into the custom CWM recovery you installed.


With the Volume keys, scroll to the option that says “Install zip” and press the Power button to select it. Scroll down and select the file that we placed on the phone earlier. Press the Power button. Return to the previous screen by navigating with the Volume buttons and then select “Reboot Phone”. Make sure you select the option that says “Yes – Fix root (/system/xbin/su)” and press the Power button.

You are now rooted! To check, install Root Checker from the Play Store or some other app that requires root and make sure you press “Grant” when the option pops up from the SuperSU app.


Now it's time to install Viper4Android on your BLU Life One X! Download it from here:

Also you need to install SELinux, which you can download from here:

On your phone, go to Settings > Security and make sure you enable Unknown sources so you can install the following programs.

Unzip the Viper4Android file and place only the ViPER4Android_FX_A4.x.apk file on your phone via USB as explained before. This is the older version that worked with KitKat and unfortunately it's the only version that will work with this phone. Install it on your device but don't open it, yet.

Next, install SELinux on your phone and open it. Select “Permissive”. This is very important or else Viper4Android will not work!

Next, open Viper4Android and install the drivers (I always choose Super Audio Quality as it gives you more audio options). Next you must reboot your phone normally.

Congratulations! You now have Viper4Android installed!

The idea of this mash-up came about when a coworker friend and I were discussing Adam Lambert’s voice and I told her his song “Underneath” on his Trespassing album sounded like a 007 Theme Song. She looked at me rather puzzled and couldn’t make the connection so I told her I would mix up some 007 footage with the song. In an effort to begin this endeavor, I thought it prudent to begin with the last Bond film made, which is Spectre. After matching the music to that footage, however, it appears like I’ve got the right mix of video and theme music, but you be the judge! I say the 007 franchise needs to contact Adam Lambert pronto!

Prototype 2 - Review

2 Anti-heroes, 1 Open City After completing the first Prototype, I was left with a bad taste in my mouth; the kind of taste where you expect

Fantastic, exceptional and professional service! I called around an hour ago and was greeted by a very kind and courteous customer service representative who told me a service technician would be calling within 15 min to setup a visit and the charge would be $69 whether there is anything wrong or not. The service technician Shane called me within 5 min and followed up with courteous informational calls to ensure that I knew I could utilize my home warranty to reimburse me. Shane the service tech showed up within the hour to promptly check the usual things, the thermostat, the air filter and then he went up on the roof. He proceeded to drain the unit and clean the coils, performing the regular maintenance to the air conditioning unit. After a thorough inspection and fine tuning, he said that my air compressor shut off due to overheating. He proceeded to recheck his work and thereupon go check my split unit in the garage which has the air filter to see if there were any points that would cause it to overheat. He replied that he has seen this before, but if it happens again to call them and he would surmise that it would be the compressor that's the culprit. I asked him what regular maintenance intervals does he recommend and he said they usually come out and check the unit in the Spring, just before the Summer, and in the Fall, just before the Winter. But for my Split System, he'd only recommend once a year due to the unit on the roof not operating at all during the Winter. Oh and it only cost me $89 for all that he did!! :D The whole experience was a delight considering the uncomfortable prospects and I will definitely use them for regular maintenance, highly recommended them to friends, family and coworkers!

LOVE! That's the only way to describe the food and the service here. LOVE! I'm serious! I was used to the best Greek Fries I'd ever tasted when I lived on 3rd St & Fillmore next to My Big Fat Greek Restaurant when it was in the Arizona Center. After I moved, apparently they left as well, leaving a horrible Italian restaurant in their wake (I won't name the horrid place). Alas, after hearing rave reviews about Opa Life from a dear friend, I finally tried it and Oooohhhh boy! It's friggin amazing awesome! And to make it even better, it's owned by the son of a dearest friend and coworker I had the pleasure of knowing and working along beside for 18 years! Please, please PLEASE eat at this wonderful restaurant and you won't be disappointed! My favorite dish is obviously the Greek Fries with extra Feta Cheese as well as the Chicken Gyro. Mmmmm Mmmmmmmmm GOOD!!!

Spinato's is... okay. Their pizza is too salty and sweet if you can imagine that for a minute. I don't remember any Chicago pizza tasting that way. I'm more of a New York style pizza lover, however, real Chicago deep dish pizza is delicious, too! This just isn't it!

This place is the BEST!!! Move over Subway and Blimpie, because Port Of Subs knows how to get er done! (Just don't let the owner hear you say the S-word! ;) The best place for sandwiches and awesome people like Crystal, who allegedly makes "The Best Sandwiches Anyone Has Ever Tasted"! I go out of my way just to buy a nice, tasty sandwich here, where the roasted chicken breast isn't a clump of chicken parts meant to be microwaved, but like a real Deli, sliced to perfection! And as a response to the reviewers on here, why would you order a sandwich from a small shop that at most has two people in it and expect them to deliver your sandwiches lickity split!?! I'm shocked they even offer delivery, because I sure wouldn't! This is a nice, low-key spot with very friendly people and it's meant to be walked into, not called on the phone! Have some patience next time you place an order and realize there are only two awesome people on staff at any given day.

This was a review I wrote on Citysearch in 2006 and they deleted it. I arrived around 7pm and I waited about an hour - not bad. I was forewarned about this so it was not a big deal. I enjoyed sipping wine outside and I showed my company, who was arriving late, the other places to park around the corner. I ordered a bottle of wine when we were seated in the Pizzeria at the bar. The seats were really hard. I glanced over to see the same hard seats throughout the very small restaurant. I ordered Bianco's signature pizza with no tomato sauce and a pizza named the "Wise Guy." The pizza was ok for a pizza from Italy. It was subpar to real New York pizzerias! When you're used to flavorful toppings and spices effervescing in your mouth (which always happens at Ray's Pizza), it's quite a let down to anticipate what is dubbed "The Best Pizza In The Country" only to find out that it's just "The Best Pizza On ASU's Campus!" It can't hold a candle to the real pizza parlors in Bedstuy or the Bronx! At the end of the night I was out of $90, but I guess I was paying for the "ambiance." By the way, what exactly is the ambiance there? I thought someone said it was romantic...well, it's not. My Big Fat Greek Restaurant in The Arizona Center has truly romantic ambiance! And their food will not disappoint - I guarantee it! DON'T BELIEVE THE HYPE!!!

I was shocked to find out there were no reviews for this fantastic pizzeria! This is basically Brooklyn NYC Pizza since it's the same owner and it is beyond delicious!!! If you love thin crust, New York style "pie" and you're in the downtown area, look no further than D T's!
