Unlock BL and root on C6606

spc_hicks09 · Mar 11, 2015 at 7:10 PM

I know there are 100 different threads on both of these subjects but they are out of date, cluttered, and unorganized. So my question is, can I unlock the bootloader on this thing and root it, or not? Here's some info:

Model: C6606
Carrier: T-Mobile
Android Version: 4.3
Build Number: 10.4.C.0.814

Any help is greatly appreciated.

*#*#7378423#*#*, then Service Info> Configuration (I guess).
If there is written Bootloader unlock allowed: YES, then you can proceed futher for bootloader unlock proccess,
If there is written Bootloader unlock allowed: NO, then your bootloader is hard-locked and you can't unlock it, it's impossible to make it unlockable.
If there is written Bootloader unlocked: YES, then congratulations, you've unlocked your bootloader!

If your status is YES and you want to get tutorial, how to unlock it, quote my message and I'll reply regarding your question.

Hope I helped

The C6606 has a non-unlockable bootloader. You can look in the service menu as explained above, but it's definitely permanently locked.

Well that was a waste of $130 then. What about root, recovery and ROMs? Any hope for that?

Got rooted by using TowelRootv3, now to see if TWRP can be installed and such. I'm guessing the locked bootloader just keeps me from flashing kernels on this phone right?

You can use XZDualRecovery.

Yes, you're correct. You cannot flash custom kernels so can't flash any custom rom that requires a custom kernel, such as CM, AOSP etc.

I have a C6606 with a custom ROM and use TWRP. I run Rajeevs 4.4.4 ROM with no issues.

As mentioned before no custom kernels with locked bootloader. Stock based only.

Data, WiFi and WiFi Calling aren't an issue?

Data and wifi are fine. I've never used wifi calling since I have unlimited talk and text and have cell service most of the time and don't really care when I don't and wifi is not available when I have no cell service. I know I no longer have wifi calling apps or what not. I finally have no t-mobile junk on my phone. It is nice.

Thanks for the input, guess I will check that ROM out. Been trying to get a recovery installed to no avail.

His ROM has TWRP in it. Install XZDual Recovery, back everything up and follow his instructions. I like his ROMs the best because there is no need to flash the kernel separately. My last Z bricked its self about 3 reboots after flashing a stock kernel with the flashtool.

My guess is that I have to flash a new firmware before flashing this ROM right? I'm on 4.3 right now.

Nope. Your ROM version is android 4.3 right now. Flashing the new ROM will update the necessary stuff. On first startup you might see messages like updating NFC drivers and so on.

Awesome thanks man! Installing dual recovery now and getting ready to flash.

No worries. Let know if you need anything else Rajeev's 4.4.4 aroma rom is a great place to start and is very bug free.

Well I can't get recovery installed because I can't find fastboot drivers. Tried downloading flashtool and it won't even start downloading. Any help on that would be greatly appreciated.

Hmm. I never needed flashtool. If you are rooted I believe there is one that you download the app, install it and have it install the recovery. I just got off work after the shift from hell and 12 days on and another 9 to look forward to so Im going to bed. Ill look for the one I am talking about when I get up if you have not found it by the. It will be in the dev area here.

Don't worry about it, get some rest. I got everything going now. Just needed the ADB files (not fastboot) and I got recovery installed, making a backup and will be flashing shortly. Thanks again for all your help man!

This is why I asked about data. After flashing the ROM, I had no data at all. I didn't know I had to manually add the APN myself.

Also, none of those ROMs contain a radio that has a baseband that allows T-Mobile LTE. If you're on T-Mobile, you're stuck with 3G or H+. So it looks like I'll be sticking with stock from now on.

Youll have LTE. Everyone told me I would not but I always did. I always had to go into settings and download the data settings.
