Xperia C2 2502 fails to start after routing

Hi,

Followed the pocedure. The first part worked perfectly.

However, after completing the 2nd part and rebooting, It just displays the sony start screen, vibrates once and the screen goes black.

Also, the power button is not working - I have to press the volume up+power button for the screen to power up. And when it does, it goes back to the second part of the routing.

Kindly advice...:)

My xperia is not opening normal phone mode it's opening recovery mode

After sony symbol my phone's screen turns blank and some philz touch 6.25.0 (clockworkmod v6.0.4.7) appears .

Also , it is saying that root access is missing
[Sony Xperia C] :
Okay, it's good you can still enter recovery. There's 2 options.

From recovery, do a factory reset and cache wipe, nothing else. Reboot.

or

Turn off, take out your SDCard, and insert ONE OF THESE FILES

If you're running C3 Dual D2502

If you're running C3 D2533

First make a backup from the recovery.

Flash the file from recovery.

This is assuming that you have a C3.

[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
Title explains it all. I've been having issues with fairly bad stutter with animations on KK AOSP ROMs. Specifically ROMs built after 8/28/14. It doesn't matter what ROM it is. Or if it's a clean or dirty flash. Custom kernel or not. After I restore all my apps, the stutter gets terrible. I'm not expecting iPhone smoothness, but this is just bad what I'm experiencing. None of the newer builds of any ROMs are nowhere near as smooth as the current build of Carbon I'm running. I just want help figuring this out because I've tried everything I can think of and I'm very frustrated and frankly I'm near giving up on updating my phone.

GS³: CarbonROM + leanKernel Edition™

Put your Kitsune up!!
[T-Mobile, Samsung Galaxy SIII] serio22:
Did you try a different launcher? Or what type of animations are you referring to?
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
All animations. Launcher, system, toast, status bar... No animations are free from the stutter. Been using Nova since I started using Android and its never given me any issues... However, the launcher animations don't get as bad as the system animations, it's just mostly the system ones that are doing it.

GS³: CarbonROM + leanKernel Edition™

Put your Kitsune up!!
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
I've been thinking about it, does it sound feasible that this might be a kernel problem? I tried running a newer kernel on my current ROM and its doing something similar...

GS³: CarbonROM + leanKernel Edition™

Put your Kitsune up!!
[T-Mobile, Samsung Galaxy SIII] serio22:
Its possible. Sorry I can't help much, I don't run aosp/cm much at all. One thing you can do though is to just turn off all animations in developer options. Some people like this, personally I don't, but you can give it a try
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
Nah man. No problem. I think I did find the culprit. I think it is the live wallpaper I've been using since I started with Android. I'm gonna give it a shot without the live wallpaper for a day to see how the ROM I'm running now performs. If it works, I can live without the wallpaper. If not I'll be back.

GS³: SlimKat + leanKernel Edition™

Put your Kitsune up!!
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
And that wasn't it. :( Even with animations disabled transitioning from app to app results in half second freezes. It literally takes that long to switch apps. If nothing is wrong and animations are disabled it should have an instant switch am I not wrong? Notification drawer is still pretty bad itself, it'll stop on its way down for a quarter of a second after swiping and resume like nothing happened... I'm really thinking about ODIN'ing back to stock and restarting with a freshly wiped internal SD to see if it'll make a difference. If it doesn't, I'm gonna have to stick with my known good build of Carbon until LP stabilizes... Ugh. I'm so frustrated with this thing right now. :banghead:

GS³: CarbonROM + leanKernel Edition™

Put your Kitsune up!!
[T-Mobile, Samsung Galaxy SIII] mp3deviant721:
Holy crap. I think I figured it out. I think it was a mod I was making to the SystemUI... I tried it without the mod and the ROM I'm running now is silky smooth... Yay!! I'm gonna try it like this to see how it works out.

GS³: CarbonROM + leanKernel Edition™

Well clean flash means no mods, otherwise you would be back to your old state. Anyway, thanks for updating your situation, hopefully this is the fix
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
chhaggerty has compiled a T900 version from source, why this thread is no longer needed and will no longer be maintained.

This is a port of CyanogenMod 12 | P900 made by bonuzzz and Valera1978 and adapted to T900 | Galaxy Tab Pro 12.2 (SM-T900).

Download T900 - cm12 v. 3, T900 - cm12 v. 5, T900 - cm12 v. 6 and an updated Gapps 5.0.x minimal (You choose what to install from Play Store, after flashing).

Flash in TWRP 2.8.0.0 or later. Here is the latest unofficial TWRP-2.8.3.0.img

attn. updated 12/21/2014 For latest versions of the ROM, check TweakerLs' MediaFire folder

His ROM-port is additionally patched with;

- Functioning Cursor

- 5GhZ Wifi channels enabled

- Bluetooth shows as SM-T900

Be patient both at flashing as during first boot it will take a few minutes and the screen will turn Black, just hang on and your device will eventually reboot, and you can enjoy cm12 Lollipop.

It's really nice and smooth. However, it's a pity that Xposed is not yet compatible with Lollipop (ART), why I will most likely stay with a 4.4.4 ROM.

Enjoy,

Thanks! What a great surprise.

Any issues at all? Screen rotation and other things that were an issue in CM11 working in CM12?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
This a P-900 port why there will be some incompatibility issues, notably the screen rotation. The alternative is to wait for someone to write it from cm sources and it might take some time.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] TweakerL:
A guess

I imagine it has the same screen rotation problem that was prevalent on the CM11 version for a while. Might want to check on how it was fixed.

Edit: using it now. Working very well
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] vi6s:
Can somebody test this and list all of the working and non-working function of the ROM? That would be awesome.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
To my knowledge there's only an issue with automatic screen-rotation. However, as I earlier mentioned I don't use Lollipop as I am very fond of Xposed. The fact that that Xposed isn't working, is not a problem with this ROM, but the fact that Android 5.0 is using ART, while Xposed only works with Dalvik.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Nomedias:
Running for two days now. I can confirm the following:

- WiFi - Joined multiple networks, no issues

- GPS - locked almost immediately after starting Google Maps

- Cameras - front and back

- Screen Cast (mirroring) - works with my Amazon Fire TV. Interestingly it would fail with the stock Samsung build.

- Hard to quantify, but it feels smoother than Samsung stock. Perhaps the lack of bloatware?

Issues of note:

- As stated by others, auto-rotate doesn't work. Is there a way to force rotation on demand?

- I miss the stock keyboard. I extracted the keyboard APK before flashing, but it fails to install. Lollipop keyboard seems plain in comparison.

- Since this is a port, apps detect this tablet as a P900. However, since specs are so similar to a T900 I doubt this will be an issue.

If anyone wants to test something specific, just ask.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
- There are a few apps that can force rotation on demand; I like Ultimate Rotation Control, but there is also Set Orientation just to mention a couple.

- Hacker's Keyboard has a lot of the same functionality, and so has A.I type tablet keyboard and a few others.

- The detection as a P900 is just visual and has no impact, other than the stated screen rotation issue. It was just laziness on my part that I didn't change the build.prop to show T900 and v2wifixx, rather than P900 and v1awifi. However, I just uploaded a version 5, with a modded build.prop.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
Absolutely correct, it's the same issue and you can consult chhaggerty's github repos to port necessary changes.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Ludespeed:
I thought having the same name in build.prop lets you auto restore your apps from google play after you wipe and flash a new rom but I could be wrong; anyone know

I use thumb keyboard for my tablet and phone; love it.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] TweakerL:
A couple of issues.

First let me say that overall I'm impressed with this build. It works quite well for the most part.

I'll just quickly confirm the rotation problem.

Now, a couple of odd problems:

#1 I can't see one of my 5ghz Wi-Fi connections. It's weird because I can see two other 5ghz connections. The one I can't see I can see on my phone, and I've changed several settings on the router to see if that would affect it. I have also killed wpa_supplicant to see if that would get it to show, but no luck.

#2 Bluetooth audio seems to be skipping a lot. I'm not sure exactly what can be done in this aspect, however, because I'm streaming music I suspect that whatever the issue is with the wifi might be the cause for the problem.

Again, overall very solid build.

EDIT: I remember that with the CM11 version, changing the country band configuration for WIFI would solve this problem, however, I don't see that option in CM12. Will look into build.prop.

EDIT2: I changed “ro.WiFi.channels=“ to “ro.WiFi.channels=14“ in build.prop, then rebooted and the missing network popped up. I'm not sure if it was just coincidence but if anyone comes across this problem I'd suggest they try it and report back results. As for my bluetooth streaming problem, as I expected once I was in the better network the problem went away. Now everything seems perfect except for rotation, which doesn't bother me because I already use ultimate rotation control on a regular basis. I haven't tested the IR blaster, but that's hardly something I use.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
Higher channels than 11 is normally only used for outside usage (U-NII-3), and is rarely used on standard routers, at least in the US, which is most likely the reason for the setting. I also believe as you suspected that the blue-tooth issues you have experienced is due to this fact. I have no issues at all with the channels, but I believe my routers set-up is channel 6.

Updated to v.6, 2014-12-17 in OP
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Ludespeed:
Is there a change-log for v.6?
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] arcadia2uk:
No. All info about changes would be in the original post in the P900 version thread.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Ludespeed:
Ok cool; thanks! Still trying decide flashing this or waiting till a sources build :)
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] vi6s:

5ghz final solution.

Did some research found the solution:

Use your favorite root file explorer and navigate to

/etc/wifi

Edit each file starting with

nvram_net

Change

ccode=GB

To

ccode=ALL

Make sure to have it mounted as RW and save each file

Reboot and enjoy all 5ghz wifi bands.

As I was logging in to write this bug report my tab hard froze and rebooted. It's the first time it's done that on this rom. Only other thing I'm noticing is that the on screen keyboard wont go away when a BT keyboard is attached. In all the other roms I've tried included stock, the OSK is hidden when BT keyboard is attached. I'm using the Samsung OEM keyboard. Keyboard works fine, it's just annoying to have 1/2 the screen covered when not needed. I've tried switching between both the AOSP and Google keyboards. Both have the same behavior.

Other that that, everything I've tried so far else seems to be working great.

Cheers.
[Galaxy Tab Pro 12.2, 10.1, 8.4 General] Tquarter:
