I went out yesterday on a long trip, it behaved good but today it was freezing on a black screen.
[T-Mobile Samsung Galaxy S II SGH-T989] oogawooga:
Freezing and rebooting after install

so i followed the instructions(except making a backup) and all i get is the robot freezing and the phone shuts off, what could be wrong?

edit: nvm i got it working after installing the radio

i have another question, i have another t989 and its not up to date, do i simply just flash it and it will work?
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
Dig deeper

Just tested the Bluetooth MP3, and the sound(music) didn't glitch this time (4/18)

And again, the device rebooted on me on the worst time ever X_X

I get mobile network to work again during my school time without WiFi somehow..... I was playing around APN settings and it worked :x

Maybe until SultanXDA release the next update, I'll be digging through my phone files and in hopes to find the bug that hides within it:silly::eek:
[T-Mobile Samsung Galaxy S II SGH-T989] Krebs830:
I downgraded to the 3/18 build, but no joy. Opened the phone and checked the SIM/sdcard connector, looked fine. Finally, I used Odin to flash and root the stock JB ROM, and the mobile connection started working again. Since this is my daily driver I think I'll stay with that, for now.
[T-Mobile Samsung Galaxy S II SGH-T989] newmab:
Did you have any issues reverting back to the 3/18 rom.

I too, had the same issue with the 4/18 rom so I tried going back to 3/18 and now it hangs at the boot screen.

Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] UNiqEz:
Me too exactly like you said
[T-Mobile Samsung Galaxy S II SGH-T989] true_lies:
just an FYI...

the wifi toggle trick for network doesn't work in roaming...only works on home network

tried for two days without success using the hotel wifi

back on home network and all's good
[T-Mobile Samsung Galaxy S II SGH-T989] zeekoshrub:
I also got stuck at the boot screen when i was using a theme. To go back without any problems i got twrp from the store, then in recovery i flashed sultan twrp, rebooted to recovery, full wipe and flashed the 3/18 rom and 5.0 Gapps.
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I switched back to the 3/18 doing a FULL WIPE of my internal SD card XD. I first follow the instruction on how to revert our virtual partition, then I do the virtual partition again and flash the Rom, Gapps, and kernle. It works fine with this method
[T-Mobile Samsung Galaxy S II SGH-T989] zeekoshrub:
Are you using 1.8.4 kernal with 3/18?
[T-Mobile Samsung Galaxy S II SGH-T989] UNiqEz:
Kernel*
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
Nope, the I'm using kernel 1.8.3

Don't use kernel 1.8.4 (maybe 1.8.4 or higher) because it's designed just for Android Lollipop 5.1 and the 3/18 Rom is Android Lollipop 5.0.2, so this could cause issues and maybe bootloop until you have flashed the right one.:cowboy:
[T-Mobile Samsung Galaxy S II SGH-T989] markusrow:
I did not have any problem returning to 3/18 rom. I restored a Nandroid backup that I had of my phone taken / made when it was last running 3/18.

If you have restored the standard TWRP, or have formatted or changed the SD card so that it looses the virtual partition, that could be a problem. You would have to go through the Virtual partitioning using the modified / special TWRP for this rom. i.e. start again going through the Virtual Re-partitioning steps.

Hope you get it right.
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I think I got it right, I have followed the revered steps and then the virtual partition steps. My phone is working no problem right now on the 3/18 rom
[T-Mobile Samsung Galaxy S II SGH-T989] newmab:
I got it after a factory reset. I was hesitant to do that since I didn't have a backup to fall back on (my fault).

All is good on 3/18.

Thanks for the input.
[T-Mobile Samsung Galaxy S II SGH-T989] oogawooga:
so im using 5.0.2 because the newest one messes up my mobile network but the problem is whenever i take a picture the phone shuts off
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
There shouldn't be a problem with the camera on 3/18 Rom, how did you install it? (or just how did you flashed from 4/18 to 3/18)

I have taken pictures with 3/18 Rom and no shut down

Oh, what is the Rom version you are on? (3/18 one is Android Lollipop 5.0.2)
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
It would be nice to also include all the kernel modifications in the settings menu too ?

That way, we don't have to go to recovery mode every time to change our settings. (I know we can still change it through app but it would be a nice touch to add)
[T-Mobile Samsung Galaxy S II SGH-T989] sw6lee:
Hi guys, I have a question.

Does the 5.0.2 version have no mobile network issue? Then which one do I have to download?

Also, I tried the latest 4/18 version and it was a bit too slow, although I loved the look a lot. I'm wondering is there any tweak or something to make scrolling or other animation a bit smoother? Like when scrolling through google now, play store or other scrolling and transition animations.

Lastly, if I want a smooth experience, would you recommend Kitkat instead? How about battery life? I haven't been using this phone, and was using iPhone for a while, but I am giving this a try with my android wear watch. I'm wondering how I can have the smoothest experience, a bit closer to iPhone. And hopefully pretty good battery life, especially on 4G.

Thanks so much!!
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I would recommend installing the KitKat version since the lollipop one is still a work in progress.

As for battery life, lollipop is definitely better. 4/18 lollipop mobile data is not really functional. So if you going to flash lollipop 3/18 since Mobile is working on that and a bit stable.

And lastly, to speed up animations... Enable developer option and edit animation speed to 0.5 (Google it)?
[T-Mobile Samsung Galaxy S II SGH-T989] sw6lee:
Thanks for quick reply!

I will definitely try 3/18. I really love the look of lollipop, and if I could have this phone a bit faster and smoother, I think I can dump my iPhone, but after using this phone, if I go back to iPhone, that iPhone (which is also bit old 5c) feels like it's flying LOL..

Especially the play store is so slow on this phone. I hope I can make it faster, but now sure if it's possible.

Also, do you know if Pimp my ROM is working on Lollipop? I remember if we increase entropy, the phone feels smoother. maybe I should try that, but I don't want to brick my phone.

Sorry for so many questions, but JUST one more thing. After I repartitioned the internal storage, I flashed this rom. But I went back to try another rom (Kitkat), and now my internal storage is acting weird. I have 11.x gb left, but there are only 2 folders: lost+found and TWRP.

I really need help on this. I'm not sure if I flash 3/18 lollipop, the internal storage will be okay again.

Thanks again!!!

EDIT: I think because of the storage issue, my camera doesn't work anymore on Kitkat.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
sw6lee, you have to undue the virtual repartitioning. Read this post, there is a link to another post at the bottom with instructions.

I actually did undo the repartitioning following the steps, but no change. But I'm not sure if I have to change from EXT4 to something else again. I didn't do that cause that was not in the instruction.

[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I didn't revert back to KitKat once I'm at lollipop but make sure you wipe you device with the official twrp for Hercules .

And install KitKat with the official twrp, not sultan's one.

P. S : I read the post of reverting and it says wipe not re partition it.
[T-Mobile Samsung Galaxy S II SGH-T989] :
Alpha. And amazing the old Herc has 5.0 running!

But Alpha... And probably a long road to fully functional. No need to ask about fixes... At all. He knows what he's doing, fixes will come, when they're fixed. :good:

Please don't quote the OP, it clutters up the thread for no reason. If necessary quote his reserved posts mention him like this: [MENTION=4800121]Sultanxda[/MENTION]

Also, [MENTION=4800121]Sultanxda[/MENTION], I can help with kernel development and features, no promises on fixing issues though. Do you think we can get a working 3.4 kernel? If we have that that will change everything. I've seen your work on the HTC Sensation, not that I own this or that, but you've done great work. Please PM me if you'd like to add some custom kernel features.

Thanks, javelinanddart
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
A 3.4 kernel actually won't change much. 3 months ago I made a CAF 3.4 kernel for this device and fixed everything except for USB OTG and crashes caused by the modem (http://xdaforums.com/galaxy-s2-tmobile/development/kernel-caf-3-4-0-kernel-t2885271). After the device entered sleep, the modem fw expl0dered and would cause a reboot. Kernel logs gave no hints as to what was causing the modem crashes, and neither did radio logs.

I don't plan on adding any more user features to my kernel except for BLN. Thanks for the offer though.
[T-Mobile Samsung Galaxy S II SGH-T989] jnmiah:

Bluetooth low energy

Hi developer,

I really appreciate this ROM. I'm running 3/18 version and its running pretty well with data working.

Can I make one request? CM11 supports this. I am using moto 360 with this phone and I would love low battery drain from Bluetooth by adding new driver to the kernel. 4.4.4 cm11 thread says they have this feature in the kernel and I really hope you can add this feature. I'm sure many of us are using android wear watches now.

Also, if you add it, I'm wondering if I can install that kernel to 3/18 build.

Thank you so much and I would really appreciate your reply!

Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] sw6lee:
Yes, that's why I wiped my internal storage, and didn't repartition it. I think we might have to repartition it back to FAT. But I'm running 3/18 build now, and I like it, so I don't think I will see my self going back to kitkat. :) Just hope we get the the new kernel feature for low bluetooth energy usage (see my previous post), and also hopefully some more performance improvements!

Also, anyone thinks they have poor touch screen responsiveness, there is an app called something like SGS Touch Calibration, and it makes samsung devices touch screens much more responsive. Now even the slightest touch registers. :)

I'm trying to set my minimum clock speed to 192MHz, but it keeps changing to 1080MHz. But status says 192MHz when I'm not using it. I'm using CPU Master, and the bar is keep changing back to 1080MHz for Min. I'm wondering if it's actually changed to 192MHz because my phone runs pretty warm, but is it because I'm on 3G?
[T-Mobile Samsung Galaxy S II SGH-T989] UNiqEz:

Hi,

I have enabled the root permission for adb and apk under the developer option. But when I run the programs they don't have root access.

I installed the root checker and it also says no root access.

In filemanager I couldn't also set the permission to root.

I tried supers as well but it don't work neither.

[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I'm not sure what you have messed up there, it works for me... But try to reflash the Rom and see if that is fixed... (Upload a logkat[log recorder] so maybe we can take a look of what is going on, but try reflash first)

Do I loose all the data if I reflash?
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
Nope, it will take time to reboot afterwards. Make sure you wipe your dalvik cache and cache before flashing to prevent unable to flash error :)
[T-Mobile Samsung Galaxy S II SGH-T989] pahlevan:
do you have some instruction how to do that?
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
OK, I supposed that you have Sultan's TWRP recovery (that is what you supposed to have to install this Rom)

1. Go to wipe

2. then click on advanced wipe tab

3. check Dalvik Cache & Cache

4. "Swipe to wipe" (and wait till it says finished)

5. go back to the start menu

6. Click install, find and select SultanXDA's Rom and "swipe to install" (and kernel [optional])

7. Wait for it to finish

8. hit reboot and wait for it to finish

9. Finished ! Now test out if it works :)

I did that and now it goes always to cynaogen recovery every time I reboot.
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
East way to do this is to have advanced reboot enabled in developer option. When you reboot through power menu you will see a lot of reboot option. Select Recovery and click reboot.

AND you get into recovery is to press ONLY Volume up and down button, not having the power button included. Since power button + volume down button is force close/reboot

[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
I have no idea what a cyanogen recovery is, but if it has a flash option, flash this <--- click on "this", download, import into your micro SD card, plug the micro SD card into your phone, open your recovery and flash it.

Then follow my steps here again (since my recovery is TWRP )

Don't flash the Roms that requires virtual partition, it won't work if you haven't done the partition

This happened to me when I dirty flash the last update. You have to use Odin to flash twrp recovery again to make it boot. Assuming you are on the latest update, use the suggested Mod TWRP . Then once you booted make sure Developers Options> Update Cyanogen Recovery is turned off for future updates.

Just saw no USB, try putting the zip file on the sdcard. The internal storage may not work due to the way it is partitioned.
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
