I have had a few email and chat exchanges with them but haven't made any progress in getting them to provide any help in unlocking the bootloader but I still have my fingers crossed. And yes, I miss htc sense also.......I didn't think I would. FYI, I downloaded Nova Launcher and I set to look much like sense.
I've also been on to their support team looking for assistance with this..... Massively unhelpful...
I asked them about possibilities of unlocking the bootloader (I usually void every warranty covering computer equipment I own within days of owning devices) and I was told along the lines of "No. This will void the warranty so we would not allow this on the device.".... Its MY device and MY warranty to void ffs!
Really gets on my tits the attitude they took.
Anyway, am thinking that unlocking the bootloader may end up like a long wait and a bit of a chore; however if anyone is able to get a dump of the stock image it would surely be possible to patch the image with Magisk then "fastboot flash" it back onto the Cat S61?
This should at least give SU access (for busybox and all that lovely stuff) as well as keeping all the FLIR/proprietary laser/VOC sensor stuff.
EDIT: I've got in touch with Bullitt Group directly instead of going through Cat, and am awaiting a reply from them regarding acquiring a factory image I can play around with... Hopefully they will be able to supply it to me!
Regarding unlocking the bootloader, I haven't tried myself yet (because I haven't got around to getting my laptop OS installed again... That's another story entirely involving bad decisions with Kali lol) but if you boot the phone into bootloader mode (power on the device by using either volume up or volume down and power button or the adb reboot bootloader command via USB). Then you may be able to use the fastboot flashing unlock command to unlock the bootloader...
LTE_D0201121.0_S61_0.040.02 is the build I'm on as well, so don't worry too much... However I've been on this build since sometime in July, so don't know why you've only just got the OTA ?
Anyway, the other thought I have been having is trying to port across a custom recovery from the Motorola Moto X4. Same chipset, same RAM, same board and same screen resolution, so it just might work... Once I get hold of a flash dump and unlock the bootloader that is I'm getting a bit ahead of myself!
Does anyone refer to this thread?
I've been looking at this phone for some time. I was able to get a Moto Z2 Force from Verizon into EDL mode with simple commands, so I'm wondering if you can unlock this bootloader just by telling it to unlock.
You would put the device into fastboot mode (by going to the bootloader, instructions were posted above i think), and then try some commands like this
fastboot flashing unlock
fastboot oem unlock
also check if in developer settings there is a toggle for Allow bootloader unlock or OEM unlock or w/e they call it.
if this works I highly suggest figuring out a way to grab the entire system to make a backup before you do anything. there's no twrp yet but it can't be too difficult to compile, but i dont have this $1000 waste of money to do any of this. i hope this post helps someone
Firehose for Cat s61
I have it if someone with a s61 wants to try it out. What exactly would you do with it? Dump your boot image maybe? Let me know and I'll post it. Makes me wonder if one could patch boot with magisk and reflash the boot image. From what I understand, BL can be unlocked by patching a couple of bytes found in the devinfo image\partition. Hummmmm
