Kyocera Brigadier APN unlock and phone disassembly

Today I will focus into Kyocera Brigadier phone. It happens that I own one, purchased from Amazon Store, but I am not a Verizon user (nor plan to be one). This is not your usual reset Android tutorial.

Kyocera Brigadier Verizon APN locked PhoneThe Kyocera Brigadier phone is a really nice macho Android device, rugged up to the point of including a synthetic mineral sapphire screen. Yep, the unbreakable screen technology that all iPhone users where expecting to get on their iPhone 6 and iPhone 6 plus but apparently Apple considered too expensive to add into their design.

Only drawback: Verizon has locked the APN options inside the Kyocera Brigadier, hence I was not able to add my own LTE provider’s APN… until now.

As it happens, today I had two news, a good one … and just to prove that ying yang concept, a bad one. The good one, which I will blatantly copy (citing the source, all in due time) will make the first part of this article, in the form of a tutorial that will -hopefully- allow you to edit APN configuration on your Kyocera Brigadier.

The bad news followed as a realization, when I inserted my nano Sim into the Kyocera Brigadier, that due to a probably forceful-ish insert, I had apparently damaged the Nano slot inside my “rugged” mobile phone.

I was shocked to say the least: My Kyocera Brigadier has been transformed into a (not so) rugged brick. It deserved a disassembly in order to reach the nano Sim slot pins and inspect the damage made.

This will be covered in the second part of this article, and it is not for the faint of heart.

Unlocking APN edit on your Kyocera Brigadier

The following tutorial was originally written by xda-developers forum user buchym and the reposted into this post.

It involves blocking the Android apps that are preventing you from editing your APN. Even if this “APN policing” code reactivate later, your already edited your APN and thus it will be kept in working condition.

So this may be the safest method of changing your Kyocera Brigadier default APN from Verizon into the one you need.

You will need a Windows PC because a windows-only tool, called “Debloater” is needed in order to stop the bloatware and policeware code inside your Kyocera Brigadier.

  1. You need to activate the Developer Options on your Kyocera Brigadier: Go to Settings then scroll down to “About phone” and then down to “Build number”. Click on the item 7 times in a row. This will give you the message “Now you are a Developer”.
  2. Open the “Developer Options” and activate “USB debugging” option.
  3. You need to have the official drivers for your Kyocera Brigadier. You can install drivers from here . Also please ensure your computer correctly detects your Kyocera Brigadier phone.
  4. Connect your Brigadier and select Media Sync Mode. IF Verizon software installation pop up appears, cancel it.
  5. Use this link  in order to download the Debloater software. Install it and skip any eventual warnings of your windows or antivirus.
  6. With your Kyocera Brigadier connected and recognized on your PC, Open Debloater software.
  7. In up left corner you have “Read Device Packages” – press it, (t will read the processes running inside your phone)
  8. Check the apps (first column) or processes (second column) that you don´t want to use.
    Search for qualcomm and check qcrilmsgtunnel.apk alias com.qualcomm.qcrilmsgtunnel (this is what block the editing of APN)  I checked all Amazon, Nhl, all Verizon except VZWService (it will mess the programmable button and every time you open the phone it will ask for program it)
  9. When you finish your selection, just click Apply and wait for Debloater to block all services.
  10. Disconnect your Kyocera Brigadier and go to Settings > More > Mobile Networks > Access Point Names and you will see in its right corner a plus sign. Tap it, introduce your APN settings and save them. When in doubt, you can check on provider’s website for manual settings.
  11. Check on mobile data: Close Wi-Fi and verify you have mobile internet.
  12. Restart your Kyocera Brigadier and verify if you can edit again APN. (if not, repeat steps 6-10)

Disassembling the Kyocera Brigadier Android Phone

First let me say that I could not find a single disassembly tutorial for my Kyocera Brigadier on the web. So, I had no idea on where to start. Upon first inspection, I was somewhat freaked out with those really weird industrial type screws on the back of the phone.

Now, the front of the Brigadier was another story: I took off the four philips screws from each corner of the screen, which in turn allowed me to take off, making a bit of pressure prying from the screen edge, up and outside; both the bottom tab holding the buttons and the slim top bar.

Then I tried the weird screws at the bottom, only to find them being plastic dummy screws, which only served as “rugged” marketing. Below one of them, I could see, at the side, a rusted out philips screw. But since it was definitely NOT below the dummy screw, I started suspecting that there was more to it than keep unscrewing things.

Hence I inserted a small screwdriver horizontally, into the hole that was left from the dummy weird screw, only to find that below the exterior back case of your Kyocera Brigadier, there is another case, being the external one glued into the one below.

I applied some pressure and managed to peel out the back outer case, or “marketing shell” from my Kyocera Brigadier.

Kyocera Brigadier Inner CaseThe second shell had six philips style screws (two of them really big ones).

I proceeded to unscrew them, and then with a plastic case opener tool, I proceeded to open the inner casing, which was also glued (but included some snap-ons at different intervals).

This required some nerves, as I did not have the faintest clue about how much force needs to be applied.

Needless to say this whole opening task left some serious dents and scratches on my new -but useless- Kyocera Brigadier phone.

As I said at the beginning this whole Kyocera Brigadier disassembly process is not for the delicate or faint of Heart.

Finally, I was “inside” the phone. The battery is not wired into the phone’s motherboard, but it rather makes contact with pressure bronce style contacts, as if the Kyocera Brigadier carries a design from an earlier phone with a removable battery.

The battery is Kyocera branded, “made in Japan”, model SCP-60LBPS and delivers 3100mah on 3.8Volts.

On the back of the inner case I found the NFC – QI wireless charger receptor, carrying the TDK brand, model 18F3-NF-K2. Again, no wire connecting the back case into the screen side (mainboard), only four pressure contacts.

Finally I got to desolder the nano sim slot metal casing, in order to reach the bronze-like metal pins that I very much suspected I had broken when inserting my Nano sim.

Yep, two of the three outer contacts where damaged. Actually the one in the middle-front is completely destroyed.

Bottom line: So much for ruggedness, Kyocera. This Kyocera Phone has a nice “manly” outer shell, but water and sand actually gets inside the inner shell and starts rusting the screws in there.

Also, I need to point out that there is a lot of GLUE used to seal the whole design in our Kyocera Brigadier phones. It felt kind of cheap.

To add into the cheap side, that matte black finish your Kyocera Brigadier got, is just an easily scratchable elastic “paint”. The usual shiny black plastic will surface “in no time at all”.

Before “upgrading” into the Brigadier, I did enjoy another water-proof phone, the Fujitsu F-01F (japan made, only for Japan Market, distributed by DOCOMO telco between 2012 and 2013).

I did open the Fujitsu F-01F too, only to find and admire a vastly better engineered water containment system and phone in general. That Fujitsu was a really cool phone. For instance, there was no need to cover the micro USB or headphone connectors.

I did have the misfortune to slip the Fujitsu phone into concrete floor, shattering the (Gorilla Glass 3) screen. This screen accident fueled my Kyocera Brigadier purchase. Now the screen is pure sapphire, but the Nano Sim Slot is pure crap and even the inner screws get rusted.

Hopefully this story and pictures may be of use for you, reader. Me, I got 100% frustrated, as I lost 400 USD on my Kyocera Brigadier and could never actually use it.

  1. So whitch phone you recomend ??? I was sooooo buying this phone and now i am in shock , i have cat b 15 but at this stage its just lagy and freezy , i was considering sony z3 compact but brigadier was just dream come true , what now ?

    1. Good question Fran … I don’t know actually. Brigadier is just hype. If you search for brigadier broken screen or similar on ebay, you will find that they are being sold as lots, tons of brigadier phones with their screen cracked. So, also the sapphire thing is wrong. I would go for Sony Z3 or Z4 … I do not like Samsung brand, but you got the Samsung “Active” line of rugged phones to consider, also.

      1. I am a construction worker and am very hard on phones. I got the Brigadier when it first came out, almost a year ago, and have not had one single problem with it. It get wet and covered with dust every single day. When it gets muddy, I wash it in the sink. Never had a screen protector or a case of any kind. Not a single scratch on the screen. So the screws on the inside get a little rusty? Who cares. It doesn’t hurt anything, as long as you don’t go forcing a sim card in the slot. Gently insert your cards, place the cover over them and there you go.

        1. hi,did you ever find out,-you wash it in the sink.,then you applicate the camera,the camera is in auto-focus mode,the camera always focusing non-stop,about 30 secs later,you can see water vapour on the camera glass from the inside.i guess it’s water can get into between the outer shell and inner shell(according to these disassembly pictures),when camera on,it’s always focusing,the camera motor’s working in high-load,the motor gets hot,it makes the water inside becomes to water vapour on the camera glass.
          btw,i must say,the top frame is fragile like a piece of hard candy,yesterday the brigadier rolled down form 20cm height,then 2 pits hole on the frame like a rat bite.

          1. Ashley, as you say, water will easily get inside. Also, I can confirm the outer layer is fragile enough. Brandon, you seem to be lucky with yours. About me, I own several phones, and I know how to put a sim card gently. As you can see in the sim connector picture, the pins design differ from normal sim sockets. They got a squarish front design, which seems to be prone to get “hooked” into the sim. Sadly, the Kyocera Brigadier was all hype, none of the “real thing” they marketed. It suffices to search ebay for kyocera brigadier cracked screen … they are being sold in LOTS everywhere. The sapphire screen, being so thin, is not as indestructible -again- as their marketing depicts.

        2. Had mine for well over a year, almost two. Have dropped in on concrete, asphalt, in the Albemarle Sound and in the sand on the Outer Banks. It is still working fine. No problems with dents, scratches, or anything on the phone or screen and take pictures of my grand baby almost on a daily basis. When or ever I am in need of another phone, it will be a brigadier.


      2. Z3 worst phone I ever bought. Had in a protected hard case and phone shattered when it fell off couch on yo carpet. Screen won’t work if cracked. Heats up and shuts down. Price of speed. Best phone I ever had was Samsung mini 3. Not advertised as water proof but I accidentally washed it without and issue. It broke when it fell off dash hoard at 110km in free way. 🙁

  2. You didn’t have to take the screws that are under the fake ones out until you took the 1st casing with snaps off like I did

    1. Can you post a quick/mini teardown of yours? Or some instructions. You seem like you really know what you’re doing and I am supposed to do a screen repair on one of these tomorrow. This seems more involved than the newer phones that I’m used to.

  3. yes maybe a broken screen if somewon takes a hammer to it, ive owned this phone for 3 years, dropped it all kinds of times, even some direct hits on the center of the screen, no damage. i even ordered another one. this phone is da bomb and has the same cpu and ram that the most expensive phones have. i love my brigidier, the only thing that will die over time in this phone is the battery.

    1. Yes indeed, the battery will die. Also, the covers on the headphone jack and usb charging port will snap off. I have a wireless charger for this phone, which I have used most of the time (I rarely charged it via a usb cord). One day, the cover was just GONE, rendering my once waterproof phone no longer waterproof. Now, about 1 1/2 years into my two-year verizon upgrade cycle, the battery drains within a couple of hours from a full charge. Verizon told me today that they can’t change the battery. I loved this phone until the battery crapped out…

  4. love this phone . can’t say enough about it . i’m on my 3rd one . i have owned every samsung and iphone .all junk . i break things easily apparently . this phone has been dropped almost daily for a year. i went swimming with my first one , without a cover over the charging port. second one flew out of my car doing about 60 mph on the fwy never to be seen again. never had a problem with the sim card port on any of them . highly recommend to anyone who breaks phones easily like myself

  5. Thanks Reset Android. The tip about the fake screws saved me some time that I would have wasted trying to get them off.
    I had the same problem of the sim card not staying in the slot, but when I looked through the six contact inspection holes in the cover I could see that all my contacts were in good shape. I was able to bend a tab in the cover to the side of the nano sim card slot that was letting the catch slip out of the detent that holds the spring from pushing the card out after insertion. I wish I could have taken pictures but my camera is in the phone I was working on. Anyway, works good now and my 3 year old Brigadier is back in service with a battery that lasts all day and then some with moderate use.
    Also, I was able to reattach the sim/SD card cover and the Micro USB cover to their tethers with super glue. (Luckily I was able to find them when they departed the phone.)
    As for the “glue” around the edges, I carefully removed all the old sealant and used some black RTV in its place to reseal the inner case. I didn’t bother with the stuff under the outer case since it has nothing to do with water tight integrity. I don’t know if it will still pass the rinse under the faucet test but I can wait until I do it by accident to find out.

    As for the Brigadier being a lousy mobile device, I can’t agree. I have had good experiences with it like several of the other commenters. I have submerged it on purpose as well as accidentally. It still received a call while in a glass of water. For a while I thought I had a scratch on the screen until I scrubbed it of with dish soap in the sink. Rinsed right off. But now it’s showing its age. It’s getting slower and I have stopped letting it update everything all the time. Oh well, I’ll have to upgrade some day soon but at least it doesn’t have to be today, yet.
