Sorry it's still not working, data continues to cut in and out. May just be that Lollipop is not going to ever be fully compatible with the old Hercules. Maybe the reason why Legacy devices are not getting official builds. Good luck.
[T-Mobile Samsung Galaxy S II SGH-T989] metalicfann:
found this on the skyrocket form worked for me for the Data issue.....

Regarding mobile data, try the following. Open the Phone app, and dial *#*#4636#*#*#* to open the Testing menu. Go to Phone information, then press the menu button in the top right. Hit "Select radio band" and choose USA Band. Report if data become stable after this.

I havent flashed the latest update but data works after I used the info on the build I'm on the Jan 25th build and if your data isn't working this should fix it.

Still no 3G data---2G fine....Jan 30

Have flashed the rom again on clean install...

still shows broken data on 3G
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
Broken data on 3G? The mobile data issue is that mobile network is getting stuck on 2G/EDGE and refuses to switch to 3G. You're connected to 3G but data isn't working at all? :eek:
[T-Mobile Samsung Galaxy S II SGH-T989] tekkieg:
3G broken

when i flashed the rom and rebooted i did not switch to EDGE...i let it go to mobile data on its own and it showed broken on 3G...the defaults you had set...wifi connected fine as always

i only switched to 2G EDGE after it would not connect to 3G

I also noticed that setting it to airplane mode overnight instead of shutting off the phone it went from 96% down to 77% on the battery.....kinda weird

on the CM 11 4.4.4 build on the 19th it stays right at the battery capacity overnight while in airplane mode which is nice....

so there is something draining that battery when no networks are being scanned.....hmmmm

I also did the Phone Testing reset to USA Band....still nothing....any other things to try?

Thank you SultanXDA...I absolutely love your work...CM 11 latest build works absolutely wonderful and I keep it in my restore folder to go back to if LP doesn't work

My mobile data, is more stable but as soon I open google play store data shuts off.

---------- Post added at 08:07 PM ---------- Previous post was at 08:02 PM ----------

Use 2g or flash another ROM. Requesting mobile data be fixed asap won't get mobile data fixed any sooner. People who are demanding only endanger that this project will be discontinued. Remember sultan doesn't work for us.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Agreed, anybody that wants/demands something be fixed you should learn what it takes to build the ROM and fix it yourself.

[T-Mobile Samsung Galaxy S II SGH-T989] md1008:
I am conflicted telling people to not be demanding increases clutter, however also a great opportunity to let Sultan know that we are appreciative of his work. Even if 3g data never works we have a very functioning ROM with working 2G data and WiFi. Some people that's all they need. Many devices I am sure that are this old and even newer phones(especially if on AT&T and VZW don't even have a lollipop ROM...if having 3G is so important you can get a Moto G for less than $100.

Many thanks. I did this before in my old ROM, but thought it was only to unlock development options... The ones that for the most part I'm probably too ignorant to make much use of. <_<

I'm in the process of downloading the 1/30 build now, looking forward to flashing it as soon as I get charged.

My recovery changed.

Its "Cyanogen Recovery" ?

Reboot system now

Apply update

Wipe data/factory reset

Wipe cache partition

Reboot to bootloader

Power down

View recovery logs

I am stuck on this.

Most installs fail. I cant change signature because option in not there.

CM 12 will load but when I hit reboot system it returns me to "Cyanogen Recovery"

same loop.

Was on Clock 6.0.4.3 and that was fine. Cant install the zip from here.

I think this S2 is done because the port is broken so I cant hook up to computer.

[T-Mobile Samsung Galaxy S II SGH-T989] JukiCro:
I didn't try to flash cm12 yet but I think you need to use last twrp recovery and check md5 everytime of rom's zip just in case
[T-Mobile Samsung Galaxy S II SGH-T989] UNiqEz:
Ok so here is my feedback,

Phone calls(incoming/outgoing) worked for me(even if it prompted me with a no sim card screen)

However if you try to pick up the phone from the lockscreen, it freezes.

If your phone goes to sleep and you wake it up too fast(where you don't get the lock)

The light on the bottom(buttons) starts goin in and out till you shut the screen off again and wait for the lock.

The audio from videos and most things don't play through the headphones,

For example, if you are using headphones with a microphone(because mic on phone sounds low for video recording) the videos play through the phone's speaker and so on.

The home button long press doesn't always work.

The task screen won't open from some apps

Like Spotify(very often), Xda Developers(sometimes) and some other apps.

Thanks sultan great work so far cx.

Running it on Hercules 989
[T-Mobile Samsung Galaxy S II SGH-T989] danrodz:
There are quite a few of us that have had zero issues with mobile data. It's worked for me almost since the beginning so its doubtful this is a compatibility issue.

Sent from my Samsung Galaxy S II Hercules
[T-Mobile Samsung Galaxy S II SGH-T989] Lourde:
Data seemed better at first, but still not fixed. While data is set to on, mobile data will work for bursts of 5 seconds or better, but rarely stay connected for as long as a minute. Initial setup after boot gave me a message that no SIM card was detected, though that didn't stop me from downloading ~10 apps over Google Play using cellular data. That initial connection was the longest-lasting and went on for long enough to lull me into a false sense of stability. Sometimes it seems like it'll come on for background processes, then shut off when I try to open something like Chrome or Pandora.

If there's anything I can provide that would help out like a log or a bug report, I'd love to know what I can do to help. This little taste of Lollipop is enough to get me hooked, Kitkat just feels so sluggish after this!
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
"rarely stay connected for as long as a minute"

What happens after it disconnects? It goes to EDGE/2G and never changes back to 3G again? Just need to re-confirm what the actual issue is so I don't go chasing ghosts.
[T-Mobile Samsung Galaxy S II SGH-T989] Lourde:
The icon displayed is the triangle representing mobile network strength with an exclamation point. This is the same icon displayed when the mobile data is manually turned off.

Tried the dialer-accessible Phone Info menu that a previous poster posted, the 4636 one:

GPRS service: flips between "Connected" and "Disconnected"

Network type: flips between "HSPA", "Unexpected", and sometimes "UMTS"

Tried toggling the radio from this menu, it's stayed steadily on for longer than normal. When I opened Chrome, it started dancing between connected/disconnected again.

UPDATE: When I'm watching it, it connects with HSPA (and the triangle with H/H+) and seems to stay that way until I try to open an app that uses the data connection. I did see it change to 3G once, but never to the E for Edge.

FWIW, There's also a category that says:

GSM disconnects: ========DATA=======
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
Oh lol, I was misinterpreting the issue. I thought data got stuck on 2G/EDGE and never changed back :p
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Then you are the first to say that. I've read several posts from people who say that it's working, and then later on they are retracting their statements. At any rate 98% of the users aren't getting fully operational data. Maybe you lucked out with a radio that is not having a problem. All the other LP ROMs for the Hercules have users reporting the same issues also.
[T-Mobile Samsung Galaxy S II SGH-T989] adrianLuna:
how i can put a different image on the lock screen than the home screen
[T-Mobile Samsung Galaxy S II SGH-T989] Lourde:
Odd occurrence. Tried to go into Pandora (no joy), then called my mother. While I was on the phone with her Pandora worked, and worked well enough to queue two songs and an ad. Went back to its old tricks once the call ended, not sure if the data cut out on hangup or if it persisted for a minute or two.

Question: Could it be a problem with my APN settings? And is T989UVMC6 still the most current radio or do I need to update?

[T-Mobile Samsung Galaxy S II SGH-T989] spit2fire4:
Actually ve not really had any data issue.. Everything's been ok with mine. The only problem i experienced with this build alone is that it takes a while to detect the data network but once it does it doesnt disconnect anymore... And even if the data network takes too long to connect i use *#*#4636#*#* and set network type in phone info to lte/wcdma and it connects immediately. I just tot its a region-band issue.. Like i said in my previous post.. This is my best rom so far.. Very impressed with it.
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
New build uploaded with another crack at fixing mobile data. I was a bit confused before as to what the problem was (I didn't know mobile data died completely, I just thought you were stuck on 2G/EDGE), which is why all the previous builds went nowhere in regards to mobile data (I was fighting a ghost, and I thought I won :p).

[T-Mobile Samsung Galaxy S II SGH-T989] Lourde:
I tried switching things up a bit: set Preferred Network Type to LTE/WCDMA in that 4636 menu and made sure that my APN was set to fast.t-mobile.com (T-Mobile US LTE, I think). Not sure if this impacted anything, but I appear to have kept my data functioning for 30 or 45 minutes. I'm going to stick with this for the weekend and see what happens.

... And I spoke too soon :(

I'll try the 1/31 once I've had a chance to charge and download.

Skyrocket

Hi Sultan,

Should we be concerned that the phone shows up as being a Skyrocket I727?

Other users reported this a few pages back and it happened to me as well using the 20150131 build still.

I know for your KitKat kernel for the Hercules this has happened in the past and you said that you had uploaded a Skyrocket kernel by mistake. Is it possible that you also uploaded a Skyrocket kernel for Lollipop as well and this could cause compatibility issues? Or is it only the text string that's wrong and this won't cause problems?

---------- Post added at 09:15 PM ---------- Previous post was at 09:12 PM ----------

Anyone has problems enabling root mode in the File Manager?

I enabled root for apps in developer options and when I switch to "Root access mode" in File Manager's settings the phone freezes and I need to force a reboot.

No reason to report bugs or have testers, as I won't be working on AOSP Lollipop. Fixing everything on AOSP Lollipop by myself for such an old device is very very very difficult and time consuming, so I will work on CM12 instead (once CM12 gets rolling).

This AOSP build was only meant to give you a small lick of the lollipop.

Can you be just a little more specific? Same apps/gapps installed? Clean flashes both times? What do you see on the battery stats display? How much difference is there?

You have to give Sultan his props here, getting lollipop running on any device is a lot of work, much less one that's been out this long. My gs2 is now my backup phone since it went bouncing across my garage floor. Now that the last major DD blocker is gone, it's time to try this again.

Sultan is the man, no doubt about it. My comment was more for curiosity rather than objection. Yes, full wipes, ROM=Sultan's cm12 vs. Bryan's pa-lp (both latest and I noticed the same with previous releases as well), pa pico gapps and finally Sultan's kernel and no apps from store.
