No problem buddy :p
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Fingerprint scanner works. You always should backup your TA partition first, so you can restore it later. I'm about to build a kernel with DRM Fix
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I guess you're safe then. Try it out, if something doesn't work, you can restore it anyway
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] JenItols:
How about all Xperia ROM's kryptonite...

Is the camera working?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
All things are working. The ROM is stable.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
You should be able to use it in US.

First you have to unlock the BL. Then flash a twrp image and flash this rom. This rom is already rooted. I deleted some useless system apps like spotify etc. but there are some apps left. That's all. Tomorrow I'll upload the second version with some other optimisations and more debloated system. I'm also making a kernel specially for this rom too. My aim is to get more than 90k Antutu score just with optimization.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Thanks for your feedback! I'll take a look at battery consumption. Let's see if disabled encryption will affect the performance, if it will, I'll add it ofc.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Does everything work? On my phone I didn't have spotify etc. after installing
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I tested the alarm app and it worked fine on my phone. Also the LED works well. Does the LED not work only when using messages app or in general?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] PRODIG4L:
Can't wait to give this a try, thanks
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Sorry guys, my provider has some problems with the internet. It could take some days, till it´s finally fixed.. On the website it says, they will fix it till friday.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
IMHO this are the speakers. On MM they were the same
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
is this rom gonna get CPU oc enabled kernel is future?! I've heard that A72 core can go up to 2.0GHz with 28nm architecture
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I may make one, but it's not good for the cpu and battery
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
yeah in case you push the cpu to it's overclocked limit all the time it could be damaged but overclocking would be awesome for dail usage smoothness and maybe multitasking
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
The cpu is fast enough for daily usage. The only thing is - benchmarks
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
Not for me man, Im getting lags here and there that annoy me

Btw, is there a way to use custom kernel with stock rom?!

I guess not...
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I don't have any lags. Why you think so? Ofc it is possible
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
Is it? Then that would be awesome, an OCed cpu with lots of governors....Im lookin forward to seein it...
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
first of all thanks! would love to see a nougat kernel with 2Ghz capability. actually 2Ghz is not overclocking, its rated at that clock for 28nm or the 2 a72 cores are. so the cpu should be fine, I do not think we will see much impact on the battery either be cause the a72's are very energy efficient. it would be interesting to have the choice and see anyway, of cause it depends much how you use the phone and what apps you are running. thanks again.

[MENTION=5647867]Kianush[/MENTION], I saw your other post(s) about the a72 cores either are stopped unless under load (as the camera post suggest) or due to an read attribute not set error on official nougat, have you tried this rooted rom to inspect further? have anyone else? also did you notice lags on MM too?

EDIT:

Bleh. Was not thinking.. if you have root i guess it doesn't matter anyway because you kan just turn them on if you want. Heh.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
I guess it's a little bit off topic but no I havent used any other roms so far. And also no I didnt see a single lag on MM...
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
Thanks! and. yeah I'm sorry to sidetrack the thread. Apologies.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
[MENTION=4906220]SGNote2[/MENTION] So Im gonna try out your rom and I have some questions to ask

1.Is it based on stock rom? I love stock sony roms

2.does xreality or super vivid mod work on it? How about stock sony camera and sony sound enhancements?

3.this one is more of a request, would you try to make an advanced kernel for this phone? I would be glad to test it or help you in any way I can

Because in case of roms and update our phone is new and does not need anything but in case of a super advanced kernel we could use some help

Thank you for supporting X compact

Tiny RCU, F2FS, OTG?

---------- Post added at 10:15 AM ---------- Previous post was at 10:08 AM ----------

1. Yes

2. Works/The same in auto mod

3. I think yes (need source code in git)
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Tiny RCU - No, F2FS - No, OTG - Yes
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] GaryFisher88:
when bro? :)

keep up the good work!
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Why not? Right now I´m testing the next version. Today I´ll upload it
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
Guess I'm a little of topic again, but could you please try and see if you can turn core 4 and 5 on with kernel auditor or similar so they are running at minimum clock instead of disabled?

Thanks a lot.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
it is kernel related. I'll implement it in mine
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
Yeah, I thought so. Thanks man.

So even now with the patched MM kernel it is faster than stock N. Heh what happened Sony? Cant wait to inspect this and the impact.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
Hey guys, Im gonna try this awesome rom todag

Please tell how to backup ta partition and restore it after rom is installed

Thanks
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
Also if it is not to much to ask; looking at the rom contents Antivirus and Spotify are not removed neither is Facebook and the sony email client that is imho not bloat is in the bloat folder. :) of course it is your decision I'm just giving you a little early feedback and in the end i can move them around myself. Keep up the good work.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I´m uploading the new version. I fixed it. 3h left.

recovery

hello,thank you for this rom.

I don't have recovery after flashing your rom.It's normal?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Yes its not included
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
thank you for your reply.

It's possible to install recovery?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
via fastboot it is possible
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] realtuxen:
Hi, could you please add SemcEmail and Exchange2 if you make another version. They can not be downloaded from the store or anywhere i know of. They come with stock Android and is not bloated like Gmail app (it's half the size). I know Sony modified it a bit but it is imho for the better. I also know i can copy it from the first zip, but i think not only me will miss the stock mail client to connect to work and other accounts. Just a thought.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
Hello,merry christmas

i've trying to install recovery via fastboot, It's seem ok but I've no access to recovery.

I don't unerstand

Have a nice day
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] JenItols:
Is your source code going to be posted?

---------- Post added at 08:16 PM ---------- Previous post was at 08:15 PM ----------

You need to flash a boot image that is compatible with the current TWRP recovery. The "Advanced Stock Kernel" thread in this forum should provide both boot image and recovery image to flash.

Then follow directions to flash ROM zip.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
what source code do you need? For now it is just a little bit modified stock
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] JenItols:
The kernel source. Not needed but figured it might be useful to open it up to others input.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
Hello,I've do that.

Your rom is installed.But I would like to flash a mod,and I can't go to recovery.

???:confused:
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
use "fastboot boot recovery.img" to boot into recovery

I´ll include the recovery into the kernel soon. Right now i´m a bit busy, sorry guys
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
Ok,thank you for your reply.

Very gogd rom
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Good news guys! I finished testing the initial kernel. Time to add features!
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
it is not possible in android 7 yet. you've to use android 6 if you want to have drm keys restored.

For now it is OC only, just to test how it goes. I want to add minimal brightness too, since the lowest brightness is waaaaay too high..
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Micka84:
The brightness thing sounds promising, looking forward
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
hey man remember to go for at least 2.0ghz for dual A72s and 1.5ghz for quad A53s...

btw an underclock would also be good since I think phone is on high clocks even on idle...
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] bromhexine:
Will screen mirorring work with this without the actual DRM keys?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
I ran into some problems with booting up tonight. My kernel just hangs on sony bootlogo, no idea what i´ve done wrong.. Then i flashed back the original kernel of this rom and got a bootloop. I had to wipe the userdata partition in order to boot up
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Yes, just flash the stock rom via flashtool and donÂ´t forget to relock the BL
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
So why didn you try the Genesis kernel?

Also cpu might be unstable on oc so even if it's enabled, it should be set on stock clock for boot up, I guess?!
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
Genesis Kernel is the same as included in ROM. The only difference is DRM Fix, it´s not in the ROM kernel. My ROM uses an advanced stock kernel I made via Root-Kernelutility. But the thing I am doing is recompiling the kernel on linux from sony´s source, that´s why it is somehow harder.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] Kianush:
Yeah I see

Good luck man we believe in you...
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] botty67:
Hi guys, I've wasted most my day trying to work out something that everybody else seemed to understand with ease.

Ive downgraded my stock rom, backed up my DRM keys but I cant unlock my bootloader. The official sony site and flashtool say that I can't officially unlock my bootloader.

I don't think I have ever had a phone that gave me the option to unlock so I must be doing it wrong. My old phone, the z3c always had ways around this so I never fully worked out if some phones just couldn't be unlocked or not.

Thanks in advance, Dan.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
Hi,visit this adress: http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/

Good luck
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] botty67:
Hi, thanks for the reply [MENTION=2555929]azaz2010[/MENTION] but thats what Im saying, If I type the code, I get Bootloader unlock allowed:No

All my phones have been like this, doesn't seem to depend on the provider.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
When I receive my code by mail,I used flashtool for unlock my bootloader

verify your IMEI.

I've tried to unlock a bootloader of my Z5C Which came from sav, it did not work because the number IMEI had changed

Sorry for my bad english
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] botty67:
Should I just request the code even if the phone is set to No?

I feel like I'm discussing something that has no merit to this guys brilliant work but I'm at the stage of just undoing all my work and going back to stock..

I had to wipe to get to this stage so I just wanna see what you guys say before I head back to stock nougat.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] azaz2010:
Yes, it's normal that your phone is on no so long as your bootloader is locked
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] botty67:
I had no luck with the code, I'm gonna give up now. I probably messed up everything now just requesting it lol.

hi all

i have installed 0.2 but i didn't backup drm keys first.

is there any way to apply drm fix to this rom in order to get cam features back?

thanx
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] littleflameboy:
hi@all too,

have the same thing running like spinhbar.

any solutions so far-is there a kernel with drm fix that works on this rom?

i try andro plus and genesis 1.02 and 1.03- but all off them give me bootloops.

thanx
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] destinygs:
I can confirm that genesis 1.03 work, that's all I can help. I flashed it using TWRP.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] littleflameboy:
ok-thx for the info.

do you use the twrp from andro+ or from oshmoun??

i try to flash the kernel zip with the one from andro and get the screen to the xperia logo and thats it.

do you just flash the kernel zip and reboot or did anything else?

thanx again
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] destinygs:
I hot boot andro TWRP and flash the genesis 1.03 kernel zip. I didn't flash andro kernel.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] littleflameboy:
TWRP

sry-just to get it for a noob.

you have 0.2 of this room installed.

boot into twrb and flash kernel 1.03zip

reboot-right?
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] destinygs:
yes
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] littleflameboy:
ok-finally i got it-man-i´m so stupid

i had the wrong supersu(2.46)-it must be 2.79-otherwise the phone stucks in Xperia logo.

last time i flashed the kernel and then direct the wrong supersu and wondering.

this time i only flashed the kernel and it boots but don´t have root. so when i then flashed the wrong supersu i know what was wrong.

so downloaded the newest supersu-boot TWRP-install supersu zip and there you go

big thanks to destinygs and all the other helping people here.

great rom sgnote2-keep on with your great work.

[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] jiangjun413:
I find the update notice to 292 in the system update, but I can't install the update using ota or flashtool due to change of the recovery. What should I do to eliminate the notice or get the update ? Thanks!
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] gizzistar:
The only way I have found is rename the update service app in system/app folder (.apk to .bk), take an apk info from the store to check the correct path of the app, and then a root explorer to rename it.
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] SGNote2:
You can freeze the notification via TitaniumBackup
[Sony Xperia X Compact ROMs, Kernels, Recoveries, &] gizzistar:
man, the ROM works fine, but there are some sony's app left, like Sketch, News, Video, Music...these app are non APKmirror if someone need them, so you can make the rom more lighter...just my thought...

Will you re-release 0.3 and if yes when to expect it?

[Android Q&A, Help & Troubleshooting] dcastro172:
So, there many ways to root a device and on samsung case you can flash a custom recovery using Odin and then flash root package using recovery.

Try some rooting apps if there's no custom recovery for your device.

I want to know valid rooting for this device because its just officially release this month December 2016.

If it was released this month, the only thing you can do is try some generic rooting apps, maybe have a exploit which works, or YOU port TWRP to it.

I return to the shop and they gave me another new one mobile, but the problem is the same no BLUE color. I tested with LED tester, Light Flow and Light Manager.

Some could say me if in your mobiles works?

I contacted with Wileyfox but they said me that maybe works or not. They don't know nothing at all because is an administrative and not a technical. I ask for a direct mail with technical staff but doesn't want to give me it.

[Samsung Galaxy S7 Edge Questions and Answers] nickster_uk:
Just tried taking a full backup in twrp but I got a message telling me that it failed as it was unable to mount data.

I get that this is due to the internal storage being encrypted.

During root, I didn't install dm-verity and force encryption disabler. If I flash the encryption disabler now, would that overcome the problem?

I've read advice that suggests wiping internal storage in twrp is the only way around it..

Thanks for any help.
[Samsung Galaxy S7 Edge Questions and Answers] BD_Man:
Nope you need to format the data partition to make it accessible in twrp. NOTE: WIPING DATA WILL ERASE ALL YOUR APPS. Make a backup using titanium. Also copy all your files from internal storage. There is no other way around this :/ You will still have to flash the dm verity decrypter
[Samsung Galaxy S7 Edge Questions and Answers] nickster_uk:
Thank you for the reply.

I've just taken a full backup of apps and data with TiBu so that is sorted.

How should I proceed now? Twrp, wipe -> factory reset/advanced wipe/format and which options should I select in sub-menus please?

And then flash the dm verity decrypter after that.
[Samsung Galaxy S7 Edge Questions and Answers] BD_Man:
Make sure to make a flashable zip file from the TiBu so you can restore those from recovery. First step is to go to the wipe menu and format data. Next swipe to factory reset. Then you can reboot to system to set everything up or install a custom rom if you wish (Make a backup of everything just to be on the safe side). Root if you want to and thats all ;)
