Same result

I love the ROM other wise Great work!... But the battery goes down by 5% every time :/ like

100%

95%

90%

85%

I wonder why?

And apps still keeps crashing randomly... Yeah.. I don't know of that's just my phone

I don't see a theme engine either what's up with that?
[T-Mobile Samsung Galaxy S II SGH-T989] Easy_as_Pi_3.14:
Yeah, that's the price you pay. We're still working on battery life. However, underclocking to 1.02GHz helps.

Also, turning off WiFi when not connected, decreasing the brightness, and turning off sync for things you don't use helps too.

For those still having radio issues, on today's build, could you first try going into recovery and wipe dalvik-cache, then reboot?

If this doesn't work, try flashing back to the 20170725 build, reboot and wait. Then once it boots, reboot back to recovery and flash today's build.

Try dirty-flashing 2017-07-25, then reboot and wait until the system loads.

Then, download 2017-08-24 and add to your sd card and reboot to recovery. Dirty-flash 2017-08-24 and reboot.

Wait until the system loads, check if the radio works.

If it doesn't, reboot to recovery again and wipe dalvik-cache only and reboot. Wait until the system loads and check if the radio works.

This is what worked for me.
[T-Mobile Samsung Galaxy S II SGH-T989] M7mD.Sa3eD:
I exactly did that, i do not know why it did not work?!

So, bryan, Is it related to SIM Unlock? , because i uses Vodafone Egypt instead AT&T the default carrier. Even though the other builds were working fine
[T-Mobile Samsung Galaxy S II SGH-T989] Peryon:
Confirmed. Both scenarios.

1. Indeed after flashing, booting and again back to recovery wiping dalvik and cache i had network signal and sim card presented. BUT after first reboot same again - no sim card.

2. I flashed back to the 20170725 build, rebooted, back to recovery flashed yesterday's build 20170824 and I had network signal. BUT again after first reboot no sim card problem reappears. Whiped dalvik/cache signal/sim card is there, but again after first reboot it's gone. (Somenone could think: don't reboot then, but... sooner or later.) I hope I made myself clear. If not - apologies. Just trying to contribute :rolleyes::good::fingers-crossed:
[T-Mobile Samsung Galaxy S II SGH-T989] _raydroid:
I haven't tried rebooting yet! When I do, I'll let you know if I encounter the SIM card problem.
[T-Mobile Samsung Galaxy S II SGH-T989] inktitan:
For me the Sim card loading is hit or miss. I do not have to clear the dalvik. Simply rebooting loads it with about a 70% success rate.

Notes on 082417 update

With the 082417 update:

--The sdcard symbol with line thru it, but I can access sdcard with Solid Explorer??????

--I get no cell signal

I first tried clearing dalvik/cache and installing 0824 over 0725 using Twrp, after reboot, I get the two conditions above.

I then cleared dalvik/cache, reinstalled 0725 using Twrp, rebooted, everything works fine.

I then tried just installing 0824 without clearing dalvik/cache using Twrp, I get the two conditions I mention at top of post.

I then just reinstalled 0725 without clearing dalvik/cache using Twrp, everything works fine.

I have attached a catlog from right after boot of 0824 when I installed it the second time with clearing dalvik/cache, Hopefully that will help figuring out what the problem is.

One another note my phone is a Samsung S2 skyrocket on AT&T network.

Disclaimer, I am a newbie with SkyRocket device and stock Android 4.1.2 ROM. I have a few questions:

1. Is the battery drain issue resolved? If not, is there a CM13 Celox ROM that does not have the battery drain issue?

2. How do I backup my current ROM?

3. How do I virtual partition my device? Is that done in step 6 above?

4. Is the 'latest official TWRP' in step one 'Official TWRP (v2.8.6-0) recovery' ?

5. What is the pa_skyrocket-5.1-20150727.zip file for?

6. If I install this ROM (Lineage 14.1 for Celox) and I decide that I do not like it, how do I reinstall the stock Android 4.1.2 ROM?

Seizure for Jeebus

Hello great minds,

Can anyone confirm/deny the LTE cell service is possible with this ROM? I'm only getting HSPA+ cell service. LTE is strong in my area. The phone's just not seeing it.

3 grueling hours with TracFone going over their APN settings has led them to believe this phone (SGH-T989 Hercules) is not an LTE-compatible phone. I argue that it must be, and despite having a 1GB data plan, I cannot get any cellular data on this ROM unless using my WiFi. Cellular Data is at 0% usage, and Cellular Data is checked as ON.

TracFone rep declared these as the proper APN settings for this phone on a TracFone network:

Name: Tracfone

APN: wap.tracfone

Proxy: proxy.mvno.tracfone.com

Port: 8080

Username: [blank]

Password: [blank]

Server: [Not set]

MMSC: http://TF.mmsmvno.com/MMS/wapenc

MMS Proxy: [Not set]

MMS Port: [Not set]

MCC: 310

MNC: 260

Auth Type: [Not set]

APN Type: default,mms,supl (one rep suggested adding 'supri' to the end)

APN protocol: IPv4

APN roaming : IPv4

Bearer: [Unspecified]

MVNO type: GID (rep was not familiar with this setting)

Can anyone shed some light on this question? Thanks in advance. Love you guys for your work!

Android 7.1.2 on a 2011 phone... I'm beaming with pride at your accomplishment!

Update: Just saw there's been a new release: lineage-14.1-20170828-UNOFFICIAL-celox

Will post back after flashing it. Maybe this issue is all for nougat.

Can someone tell me if I need to repartition the phone ? If so, how can I flash the original pit file ? Once this is fixed, I follow post #2 ?
[T-Mobile Samsung Galaxy S II SGH-T989] Peryon:
If I recall right. I pushed it through Odin. I found on xda forum how. Don't remember where. Found "original" pit file and push it. Then I followed Bryan's steps. I had to do it because my partition was too small. I definitely recommend nandroid backup first. I'm not sure your partition is big enough. Especially if you use big apps. There's no option in this rom to transfer apps to sdcard. (Please, guys, correct me if I'm wrong. I'm not pro.)

Did you try to install this rom already?

p.s. you can see my memory stat below...
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
I don't use this phone too much as it seems to crash once in a while. That's why I want to try a newer rom and I'm worried that I'd spend too long trying to fix it if I mess up the pit file and flashing the ROM. I don't need to backup any data or apps from my phone as there's nothing much on it.

I did find a website that claims to have a pit file for the T989 / T989D. Here's a link to it.

I'm a bit confused about the instructions from post #2. Before I start, can you tell me if my interpretation of the process will work based on my current OS as indicated in my previous post:

1. boot phone into download mode and use Odin to flash the pit file in the link above.

2. reboot phone into download mode and use Odin to flash Official TWRP (v2.8.6-0) recovery from Post #2. Reboot phone into recovery.

3. In TWRP, go to Wipe -> Advanced Wipe -> check Internal Storage -> press on "Repair or Change File System" -> press on "Change File System" -> press on "EXT4", and then swipe to start formatting the internal SD card. This can take up to a minute.

4. Wipe Data, Cache and System.

5. What exactly does "Copy the newest version of my TWRP recovery to your device and flash it" mean ? Do I just connect my usb cable to my laptop and copy Virtual Partition TWRP recovery to a folder on the phone. How exactly do I flash it as I thought all the folders/OS will be wiped out in step 3 above ?

thanks for your help
[T-Mobile Samsung Galaxy S II SGH-T989] gregrwm:
that does seem confusing. i don't use odin, i use heimdall on linux, but still, other than choosing the proper TWRP file at the proper time, flashing the "Official TWRP" and flashing the "Virtual TWRP" should work exactly the same.
[T-Mobile Samsung Galaxy S II SGH-T989] Peryon:
Ok. I used odin just for puhing pit file. Nothing else. Then i flashed TWRP over CWM. (Clockwork mode - recovery tool too.)

Do you have any recovery installed? I believe you do if you already partitioned and rooted the phone. If so flash proper twrp recovery bryan posted and then virtual partition twrp recovery (from second post). Then follow steps.

I even used 2.8.6-0 version for these steps. You can update it later.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
Thank you for the reply.

I have TWRP v 2.5.0.0 installed on my phone. Just a few more questions.

1. Once I flash the pit file with Odin, will it wipe out my OS ? Can you confirm the pit file I linked to in Post # 1209 is the original pit file for the T989 ?

2. To install TWRP v2.8.6, do I just copy that to my external sd card and then boot into twrp and flash it ? I know it sounds like a silly question, but I don't know if I have to flash a stock OS after installing the pit file ?
[T-Mobile Samsung Galaxy S II SGH-T989] Peryon:
1. Probably. 1.b I can't confirm it at all.

2. Yes. Then restart recovery. 2.b No.

P.S.:

Dude, you gave me homework! Did you follow this post when you partitioned?

https://xdaforums.com/galaxy-s2-tmobile/development/mod-partition-internal-memory-t-989-t3051556 looking at your posted pictures of memory distribution I presume you did.

I did

. And I used their unmodified pit. file to go to original state.

https://xdaforums.com/attachment.php?attachmentid=3204690&d=1426053881

But as you said you have t989D! so I'm not sure is it same.

comfirmation.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
It is possible I followed the pit flashing instructions in the post you linked to above. But I'm not 100% sure. All I remember is that the ROM I wanted to install required that I flash a new pit file. Thank you for the link to the pit file. The interesting thing is that your file is 500kb and the one I linked to in my previous post is only 137kb. I will flash your pit file since you've actually used it. Just to confirm, your model is the T989 (not T989D) ?

As per this link, the T989 and T989D have identical hardware. They are only different because they have different radios flashed on them ?
[T-Mobile Samsung Galaxy S II SGH-T989] Peryon:
I have T-Mobile t989. We need expert to confirm is it safe (or will it work) to use pit or rom on t989D! I believe that someone here has D! model.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
According to post #2 in this link, "As far as roms go, you can use 'any' that is made for hercules/T989, the T989D is basically just a Canadian version of the T989."

So I will try this Lineage ROM in a couple days. Basically, I will Odin the original pit file, flash the twrp. Format all partitions to ext4 and partition internal sd to Fat32. Then flash the new twrp and roms. Keeping my fingers crossed:fingers-crossed:

Edit: just reread post #1 here. What exactly does this mean, "*You must have completed the repartitioning process in order to install the TWRP recovery updates" ?
[T-Mobile Samsung Galaxy S II SGH-T989] gregrwm:
it means just what you just said you're going to do.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
I tried using Odin to flash the pit file you linked to in your earlier post. Odin didn't seem to do anything. I did not get any message to indicate the process was complete. I gave it a few minutes before I unplugged the phone and removed the battery. The phone would only boot into some error screen. I had to use Odin to flash TWRP 2.8.6hercules.tar. The good thing is that once I loaded twrp, I'm able to boot into my my phone and see all my apps and the phone is just as good as before I tried flashing the pit file.

Any idea why I can't flash the pit file. Is it possible that my pit is permanently not modifiable ?

edit: Since I'm having problems with the pit file, can I flash a stock rom and this will also revert to the stock/original pit settings ? This link suggested it, but I don't know if it's true ?

sure would be nice to hear from someone who'd repartitioned. i hadn't. i remember fussing with heimdall, seemed some flash operations wouldn't go, never knew whether to blame heimdall or the phone, sometimes just trying again made it work, might be the same with odin.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
I agree. It will be nice to get a step by step instructions on how to restore the partitions. I thought flashing a stock rom would restore the stock partitions ? Can someone confirm if this is true and if so how to do it with Odin ?

[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
thanks Gregrwm. That was the post I followed except I Odin'd the unmodified pit file. Which never completed. If I was successful in installing the unmodified pit file, there is no instructions on how to proceed next (ie: do I flash a stock rom or a custom rom ? Do I flash twrp or cwm ? Do I have to format certain partitions ? )

EDIT: there is a little instruction on this link but it doesn't exactly explain how to partition the phone.
[T-Mobile Samsung Galaxy S II SGH-T989] gregrwm:
With heimdall iirc you can repartition, flash (the "original") TWRP and boot it up all in the same step. No idea maybe odin can too. Anyway if it doesn't seem to work i'd try it a couple more times, though being familiar with neither odin nor partitioning i can't tell you what hint of success to look for. After trying it a few times i'd just try to carry on with the instructions in post #2. Whether you need to be bothered with backups or not there really aren't that many steps either way.
[T-Mobile Samsung Galaxy S II SGH-T989] sylvestor2013:
I am not familiar with heimdall iirc so I'd like to stick with ODIN and twrp software. I just need to know exact steps to put my partition back to stock.

MTP not working

I installed over the weekend the LineageOS 14.1 ROM to my almost retired Galaxy S2 and I was so glad I could bring back to life. Great work!

While everything seems to work great, I have been unable to get the MTP mode when connecting a USB cable to work. As a matter, the only mode that is working is "Charging". I have tried drawing down the status bar when plugging in a USB cable and selecting the "Transfer Files" mode, but it almost instantaneously reverts back to "Charging" mode. I also tried under Developer Options to change the "Select USB configuration" option to MTP but again, it either reverts back to "charging" or it shows MTP but when connected to a PC there are sounds of connecting and immediately disconnecting.

Has anyone else experienced this issue? Is there any setting that I need to select?

I'm trying to revive this old SGS2 so that I can experiment with Android Auto in our new car. MTP is needed for Android Auto to work.

Thank you

I have questions about optimization, but first, I would like to thank the community (especially the OP) for providing this ROM. My S2X had been sitting in the closet collecting dust, and I was happy to bring it back to life and get some more usage out of it.

I've followed the instructions on the 1st post to flash this rom and thus far it is working well. Coincidentally, I also resurrected my S2 (I9100) using the instructions at https://xdaforums.com/galaxy-s2/development-derivatives/rom-t3555834. Comparing the user experience, I found S2 (I9100) to be a LOT more responsive in terms of usage to a point that I wouldn't mind using S2 as my daily driver. S2X, on the other hand, often struggles with launching an new apps, loading a webpage, etc. While it is fully functional, I wouldn't really use it on a regular basis.

I already disabled all animations.

digging into the details of these two instructions, one realizes that:

- S2 has a custom kernel

- the instruction for S2 suggested to use F2FS for data/cache

My questions are:

- is there a custom kernel for S2X (without building my own),

- I'll be experimenting with using F2FS for data/cache to see if it provides any speed up, but any comments on using different file system is appreciated,

- any other tip on how to optimize user experience?

any comment/suggestion is very much appreciated,
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I experimented with F2FS on several devices, including my old S2. Unfortunately, I didn't see any appreciable gain.. and almost always had issues with the partitions down the road. Now I stick with Ext4 and experiment with IO schedulers for better throughput.

I've kept the kernel that is packaged with Bryan's roms and use a kernel manager like Kernel Adiutor to tweak settings. I find that more aggressive LMK settings make a huge difference in the day to day use. I also tweak the CPU governor for better interactivity.

You should follow the directions HERE to repartition back to stock.

You'll also need to install Samsung USB drivers, if you haven't already. You can find that in the ODIN thread HERE.
