Hello,

Yesterday I picked up a T-Mobile Z1S and rooted it via TowelRoot, installed a custom recovery, and manually debloated the /system. Which is all good, however, I want to know if any of the ROMS here in this forum can be flashed to it, considering the Z1 and Z1S have the same processor. Anyone have experience doing this? Thanks.

I could not get towel root to work with my z1s. You just ran it and had root?

I have tried a couple yes with no luck.

I rooted a little different than others. First I used the jcase method, installed the dual recovery and installed SuperSU. From there, I installed TowelRoot and ran it, rebooted, then flashed the latest v2 SuperSU. Sounds a little redundant I know, however, now I have permanent root, and also read/write permissions in /system, even after reboot, without running those ADB commands all the time.

I'll try to get a good system dump from my Z1S, and release a ROM that doesn't affect the kernel, which should be able to be flashed via recovery. Since the ROM will only be /system mods, it shouldn't matter if the boot loader is locked still. Inform me please if I'm mistaken.

I think that should be right, I thought the bootloader only prevents booting if the kernel isn't supported/allowed

No, you are correct.

As long as it runs on a stock kernel then you can have a locked bootloader. the whole of the development section is full of roms like that
The original development section is for mods/roms that need a custom kernel or a non stock boot.img

After multiple issues I was finally able to get dual recovery with root last night. After sifting through the forums looking through roms, all of them required different firmwares, will the c6916 take firmwares from other z1 devices. If so then as the above poster said, there is loads of roms in the development section that will worked with locked bootloader. The only reason I ask is the posts list different device model numbers and the c6916 is not listed on any.

Our devices have a 4.3 kernel that cannot be changed due to the bootloader being locked. Flashing a 4.4.X ROM will most likely not boot due to needing a 4.4 kernel as well. However, 4.3 ROMS modified to not flash the kernel, just the /system should boot fine.

When trying to boot another custom stock rom make sure you change the.
1. Libandroid-runtime-so.
2. Libandroid-servers-so.
Without not changing these it will not usually not boot up.

In my phone configuration it says
Bootloader unlock allowed: yes

Does this mean I can unlock my bootloader?

    I'm using cyanogenmod z1 on my Xperia Z1s. I was able to unlock bootloader on developer.sonymobile.com. The only thing to keep in mind is:
    1) Z1 firmwares are using 16gb of on-board storage instead of 32Gb
    2) You have to manually replace z1 (i'm using c6906) /etc/sensor_def_qcomdev.conf by the file taken from TMO C6916 firmware - if you don't do that - you will have wrong screen rotation behavior.

    This is all very exciting! Once I'm not in the middle of a time when I really need my phone working I'm definitely going to try this.
    Anyone else have success? Also any updates about ROM or kernel installations?
    @shefys Which specific cyanogenmod for the regular Z1 did you install? or did several different versions work? (From your various posts it seems like you've had success with both stock and cyanogenmod roms)

    I might be trying to do this tonight, I'll report back.

    Edit: oops actually gonna try the other one that can be done without unlocking since I didn't have any luck with that part.
