This ROM is abandoned for a long time already.

You can consider trying another ones like http://xdaforums.com/galaxy-s2/development-hd/rom-5-1-1-cm12-1-samsung-galaxy-s2-shv-t3250745 or http://choimobile.vn/threads/android-5-1-1-r6-lollipop-cho-may-shv-e120l-v10002-15-07-2015.54364/ for example.

Thanks. Already tried cm12.1. Too many issues like HD games not working, optimising apps on every boot,etc. And the second link is not working. Too few development for our devices compared to gti9100 version.

Hello there. Can you tell me if there is a TW based 5.1 rom under development for this device? I really love TW features but i dont like jellybean anymore.
[Galaxy S II HD LTE Android Development] diabolicalprophecy:
Sad to see this device is dead. The last ROM update was about a year ago which was CM12.1. I am thinking about giving it away now.

I think the download link is dead :(

Good rom, thanks socim. I waiting a new rom for E120S
[Galaxy S II HD LTE Android Development] nadliw:
Thanks Socim. But I am a bit unclear about "switched dalvik to art after flash". After reboot the problem still occur.

As usual when I flashing a ROM, I wipe data/factory reset, cache partition wiped and dalvik cache wiped. Please correct me if I am wrong... back to basic ROM flashing...:o
[Galaxy S II HD LTE Android Development] Socim:
Do you have the latest modem flashed? AFAIK obsolete modems won't work after cm10.2.
[Galaxy S II HD LTE Android Development] nadliw:
I never thought about the latest modem. My Baseband version now is M9600B-SCAQSVZD-3.1.613102T. I got this after restock with ICS rom.

For the latest modem should I do restock using the latest stock rom? Or any flashable modem via CWM can do?
[Galaxy S II HD LTE Android Development] Socim:
I have just uploaded it and you can flash via CWM.

baseband-E120LKLJMK3.zip
[Galaxy S II HD LTE Android Development] nadliw:
One day using this ROM. I can say it works almost perfectly...for me. Thank you Socim for the latest modem version.

I do underclock max frequency to 1404MHz and min frequency 432MHz by using INTELLIDEMAND governor and I/O scheduler. With this my phone wakeup faster but sometime it is hard to turn on screen.

Socim, hope you will continue improving this ROM and the page of this thread will increased with info and discussions.

Thank you.

hello guys, i just got this phone and i want to install this rom. the phone is fully stock

i flashed via odin the cwm from first post but i cant get into it, the odin shows that flashed properly.

can anyone help me how can i do it?
[Galaxy S II HD LTE Android Development] OccsE:
Hi!

Something wrong with this ROM for me :(

I use "wipe for install a new rom" after Wipe Cache.

Go to Install ZIP and choose this file: [GApps][Mod][4.4.2][AROMA]_Aroma_Installer_GApps-v1.5.2

Begining.... After "System Apps List"

I choose: Google Maps, Google Earth, Youtube, Quick Office... Next -> Yes

I choose: Browser, CMFileManager, CMWallpapers.... Next -> Yes

Installation. "Installing Aroma celectable gapps. Mounting system...."

"file_getrop: failed to stat "/system/build.prop": No such file or directory.... -> Next (button)

Installation Completed

Choose: Reboot you device..... Finish... Rebooting... See that: "Samsung" and after nothing :(((

Only black monitor. Why?
[Galaxy S II HD LTE Android Development] Socim:
Power off the phone, then hold volume keys, turn on. It will boot into recovery.

It's gapps, not ROM. You need to flash a ROM first.
[Galaxy S II HD LTE Android Development] leonleonleon:
Thanks a lot my friend, I did it. But I got some problems.

I flashed the cwm via Odin. Then flashed the touchwiz.

After that I flashed the bootloader provided by ts.

After that the hellkat rom and the gapps.

The phone works but I have screen bickering issue, I think when I am using SwiftKey it does it more. And my connection is loosing w n I am using the 3g Internet.

Any advice?
[Galaxy S II HD LTE Android Development] Socim:
Sorry I am confused. What is "the bootloader provided by ts"?

I don't know where are you from, but AFAIK, SHV-E120L is not a good 3G mobile, it only support 3 freq bands, so if your carrier use another freq I am afraid it won't get any signal.

Please try to flash http://d-h.st/nPL via CWM to resolve screen tearing.
[Galaxy S II HD LTE Android Development] leonleonleon:
Οι

I ment for the baseband on your 25 post, sorry for my mistake, I was too sleepy.

I am from Greece and I didn't had any problems with stock rom with the network.

The 3g works very well but there are instant disconnects while I am at apps that use the data. With viber I am speaking with 3g without any problem. The disconnect/connect time is instant, neither half second.

I flashed it but the tearing is still but less I think.

Another thing I see is the high battery drain, over night 4 hours idle I lost 16% battery. It is too high, does everyone has drain like this?
[Galaxy S II HD LTE Android Development] Socim:
I have just built a new kernel and no screen tearing so far, maybe a new ROM will be available tomorrow.
[Galaxy S II HD LTE Android Development] leonleonleon:
OK I will wait for it. Do you know anything about the other issues?
[Galaxy S II HD LTE Android Development] Socim:
AFAIK, there are some background jobs once a new ROM has just been flashed, for example media scan.

Have you encountered any SOD?
[Galaxy S II HD LTE Android Development] chir0n:
Finally!!

After a long wait somebody finally came up with a CM for our devices! :D

Many many thanks Mr. Socim! We're truly grateful!!!

Downloading now~~
[Galaxy S II HD LTE Android Development] nadliw:
My carrier only provide 3G band. Is this mean why I cannot send SMS?
[Galaxy S II HD LTE Android Development] Socim:
I don't think so. Maybe you can try to correct the SMSC number by dial "*#*#4636#*#*" without quote.
[Galaxy S II HD LTE Android Development] Socim:
Also, a new ROM will be uploaded later, it seems SODs are gone, also no screen tearing so far.

[Galaxy S II HD LTE Android Development] Socim:
No need to full wipe or re-flash gapps. Just flash it then wipe dalvik cache & cache partition.

[Galaxy S II HD LTE Android Development] rxulan:
Hey guys,

what is the exact way to migrate from stock 4.1 firmware to Hellcat?

1) Flash CWM via Odin (as PDA).

2) Install PhilZ Touch(Flash via CWM).

3) Backup the data you need.

4) Factory reset, wipe dalvik cache, format /system, format sdcard0 (to ext4). Formatting sdcard is important to prevent some weird bugs with networking etc.

5) Install Hellcat ROM via CWM (no reboot after previous step).

6) Install Gapps via CWM (no reboot after previous step).

Enjoy.

Is it correct? Thanks :)

EDIT: installed in the way above, everything went smoothly. Thanks a lot!
[Galaxy S II HD LTE Android Development] goldy_rocky:
Guys I am noob.

Can anyone tell me the complete step by step guide how to flash this ROM & which file I should Flash first

[Galaxy S II HD LTE Android Development] rxulan:
Suddenly the ROM has failed to work with modem part. After some time of flawless operation (~ 1 hour) the phone is unable to find and to connect any network, just like there's no SIM or no modem at all.

Flashing back to the stock ROM resolves the problem (network works fine, so the network itself and the simcard is ok apparently).

Flashing Hellkat once more and got no network available again. In the settings, "About phone" reports "Baseband version: Unknown".

Any thoughts?
[Galaxy S II HD LTE Android Development] nadliw:
I can confirm that...

Same happen to me yesterday...
[Galaxy S II HD LTE Android Development] Socim:
Cheers! You just forget to mention backup your message and app data by Titanium Backup or similar app.

Glad to see you again. Rxulan has already done the job.

Please shut down the device then turn on again, then it should work well. Reboot doesn't help.

For me it sometimes occurs after flash a new rom, only 3 times. If you can post a logcat after lost your signal it will be appreciated. Please note, your logcat may have sensitive information.
[Galaxy S II HD LTE Android Development] rxulan:
I tried to shutdown the device (even unplugging the battery), but it didn't help regrettably. Will try again.

It looks like the ROM system loses connection to the ROM modem part somehow.It can't recognize the baseband version at all, and unable to read a simcard (E120L at least. Probably because it has 2 modems and the connection is messed by ROM - just a guess).
[Galaxy S II HD LTE Android Development] rxulan:
Now modem doesn't work from the start. Power off/on doesn't help (multiple times, no success).

I could send you my logcat via PM if you don't mind, hope you'll keep my sensitive data private ;)

EDIT: but it looks like PM doesn't allow to attach files.

---------- Post added at 01:24 PM ---------- Previous post was at 12:32 PM ----------

Weird, but I can't send PM as well. Tried 3 times but there're no PMs in my "Sent items" folder.

---------- Post added at 01:27 PM ---------- Previous post was at 01:24 PM ----------

Hell, I just didn't set an option to save copy of PMs in my "Sent items" folder. What a stupidity.

Socim, sorry for spamming you with same PMs :eek:
[Galaxy S II HD LTE Android Development] rxulan:
Additionally, IMEI is not detected as well for the phone. It's getting back when you flash stock ROM (without restoring /efs). So one of the causes maybe that Hellkat loses /efs partition or something (probably some RIL issues?).
[Galaxy S II HD LTE Android Development] khan1989:
Hi guys, for me the phone automatically reboots when taking a picture.

Anyone else facing similar issues?

Edit: Seems to only happen when flash is enabled.
[Galaxy S II HD LTE Android Development] leonleonleon:
I can confirm that with the camera, I will try the new update after Monday because I am off the city.

Socim is there any way to fix the 3G signal loosing problem while using data? And someone wrote about a new official 4.3 update, you saw anything for it?

Thanks again for supporting this phone.

[Galaxy S II HD LTE Android Development] rxulan:
Good news guys.

Following an adwise of another user, I reinstalled the ROM again but performed deep system clean, namely: wipe/factory reset "to install new ROM" (recovery formats /data, /cache and /system partitions) and (important!) format sdcard0 (I've chose ext4, don't know if it's correct or not).

After that, network/modem issue for my E120L is gone. Network is working for now.

Mobile standby

Hi again Socin,

One day using your rom and battery consumption on mobile standby really got my attention.

Where I live we dont have a good cell signal, and inside the house almost zero.

Even though, I was not used to have so much of battery drain because of it using SVNRom 1.7.

((( Attached sceen shot )))

Thx for your work!

BTW, although I love hellkat special features I don't like the red theme as well, but I don't have time to change it...

I have almost no idea. Probably you can put 2G/3G switch to quick settings panel, then turn the device to 2G mode once you don't need to surf the internet.
[Galaxy S II HD LTE Android Development] yakie47:
the rom gotten even more better with the latest update, but the same echo sound that the 1st time appeared in CM10 while making phone calls appeared again in the latest build, i don't know whether i'm the only one facing that issue or it's a bug, another one is that i can't seem to install big sized apps downloaded from the market, they don't start and i get error, as for the battery life it's good as well as everything else i believe..
[Galaxy S II HD LTE Android Development] leonleonleon:
About the network you are saying. You mean the 3g disconnect issue is solved?

My 3g is disconnecting every time when I am using the data, it disconnects and connects all the time. Is there any fix for that?
[Galaxy S II HD LTE Android Development] rxulan:
My issue was the absense of network at all after the ROM installation.

As for the 3G disconnects, I'm not sure because I had no network connection before. Now it works regardless of using voice/data. The latest baseband is flashed.

What is the default filesystem for E120 internal memory (sdcard0)?
[Galaxy S II HD LTE Android Development] Socim:
FAT32 is the factory default FS, but I prefer exfat if you still need to transfer files in mass storage mode with Windows.

Ext4 is a good choice since it is a journaling file system, it reduce the risk of data loss/corruption. Please don't try to format it as NTFS, though it is also a supported journaling file system.

Please note stock ROMs will format it to fat32 again without notice, so, back up your data before flash back to any stock ROM.
[Galaxy S II HD LTE Android Development] rxulan:
Hmm. I formatted sdcard0 to ext4 but it looks like any programs are unable to write data on it. Even camera app asks to insert sdcard first. There's no any data on it excepting /clockworkmod and /lost+found folders.

Should I reformat it to fat32 (or ext2 probably), or is there a way to go with ext4 correctly?
[Galaxy S II HD LTE Android Development] Socim:
Try:

su
chmod -R 666 /storage/sdcard0
[Galaxy S II HD LTE Android Development] rxulan:
Things getting even more weird. Using CWM recovery, I formatted sdcard0 to ext2 with no effect. Tried to reformat it back to ext4 - failed (unable to format sdcard0). So, I'v chose to format to "default" option which was successfully completed. After reboot, I got that "no network" effect back. Great, lol.

There's something to do with sdcard0 filesystem obviously (or its permissions at least). I have no idea where to step now.

Is there something to fix in ROM in this regard?

---------- Post added at 12:43 PM ---------- Previous post was at 12:36 PM ----------

Tried it before (with ext4) and it gave me "unable to chmod ... read-only file system" error.
[Galaxy S II HD LTE Android Development] Socim:
Try mount it as mass storage then format it as exfat under Windows or ext4 under Linux.
[Galaxy S II HD LTE Android Development] rxulan:
And there's something about "unable to chmod ... read-only file system" error (appended my previous post).
[Galaxy S II HD LTE Android Development] Socim:
Try:

mount -o rw, remount /dev/block/mmcblk0p28 /storage/sdcard0
[Galaxy S II HD LTE Android Development] rxulan:
Heh. Tried it but never succeeded. The phone is getting self reboots everytime but before the operation is completed. Now it seems that I lost sdcard0 because the partition is gone and it's even impossible to format it via recovery.

Probably adb could help, but I have no experience on this.
[Galaxy S II HD LTE Android Development] Socim:
Is it possible to mount the phone as mass storage under recovery? Go to the mount menu and find the last item.
[Galaxy S II HD LTE Android Development] rxulan:
The things I did before were done under recovery really. This was a mistake as I take it now.

So, currently trying to get into adb shell parted things to recover sdcard0 partition back.

But yes, operations I perfomed before were made under CWM recovery 6.0.4.5 (touchless).
[Galaxy S II HD LTE Android Development] Socim:
Can you please let me know which recovery is flashed on your phone? I guess it is not the touch version?
[Galaxy S II HD LTE Android Development] rxulan:
It's PhilZ touch 6 (CWM 6.0.4.5 based). When I mount USB in recovery, my Win8 PC don't even recognize it.

Although Ubuntu 12 VM does.

---------- Post added at 02:48 PM ---------- Previous post was at 02:33 PM ----------

Touch version is definitely better. Managed to format sdcard0 to ext4 under Ubuntu VM now. Thanks a lot, Socim.

---------- Post added at 03:04 PM ---------- Previous post was at 02:48 PM ----------

Tried it, only got falling back to the mount usage help and then to the shell command line.

---------- Post added at 03:33 PM ---------- Previous post was at 03:04 PM ----------

Finally, succeeded with

but still no effect. Apps can't write anything to it. Can owner/group be the cause? Currently it's root/sdcard_r for sdcard0.

---------- Post added at 03:57 PM ---------- Previous post was at 03:33 PM ----------

Rechecked it and found out that despite chmod -R 666 /storage/sdcard0 command goes smoothly through command line (no error reports), actual permissions of sdcard0 stay the same (drwxrwx--x),
[Galaxy S II HD LTE Android Development] Socim:
Maybe you should try

mount -t ext4 -o rw,remount /dev/block/mmcblk0p28 /storage/sdcard0
[Galaxy S II HD LTE Android Development] rxulan:
Should I do it under recovery or under Android?

---------- Post added at 04:25 PM ---------- Previous post was at 04:15 PM ----------

Carried out the command with no errors, but still no effect (no apps can write to sdcard0). Weird.
[Galaxy S II HD LTE Android Development] Socim:
At first, you should check if it was mounted in read-write mode, then you may need to try chmod again.

su
mount
ls -al /storage/sdcard0
chmod -R 666 /storage/sdcard0
[Galaxy S II HD LTE Android Development] rxulan:
mount and ls commands given me this (at the screenshot).

chmod gave me "Unable to open /storage/sdcard0/lost+found: Is a directory".
[Galaxy S II HD LTE Android Development] rxulan:
Ok. Triyng to refer to the point /mnt/media_rw/sdcard0 for chmod does the job partially. It changes permissions up and down but still unable to set rw to the world (x only). So chmod 666/chmod 777 doesn't change the story anyway.
[Galaxy S II HD LTE Android Development] Socim:
So I am afraid that you may have to format back to exfat or fat32, as void (the Android mount service ) lacks ext4 support.
[Galaxy S II HD LTE Android Development] rxulan:
This will most likely lead back to preventing of modem to work. It happened earlier today I formatted sdcard0 to fat32. Probably there's something that doesn't allow baseband to work with fat partition (no idea why).

---------- Post added at 09:02 PM ---------- Previous post was at 08:50 PM ----------

Wow. I can't really explain it but it's working now. Probably the last time I changed permissions for /mnt/media_rw/sdcard0 took effect. Although it reports rwxrwx--x permissions for sdcard0. Who knows...
