[CM][i705][VZW-LTE] CM12.1 Unofficial

CyanogenMod 12.1 is a free, community built distribution of Android 5.1 (LolliPop) which greatly extends the capabilities of your phone.

This is the unofficial Build of CM12.1 for the Samsung Galaxy Tab 2 I705 VZW LTE version.
**IMPORTANT** I705VRBLL2 FW required,if you have taken the latest OTA, and were not already rooted/unlocked you will not be able to use this ROM.
There is not root/unlock solution for the latest OTA. See more info in the last few pages of the linked root /unlock threads below.

To hear about the latest updates and changes to CyanogenMod as a whole, please follow +CyanogenMod on Google+!


Installation Instructions (These are all required)
ROOT and BOOTLOADER unlock required following the linked guides.
Flash THIS custom TWRP recovery with SELinux capabilities.
Download latest ALPHA from http://downloads.codefi.re/jrior001/cm/espressovzw.
Locate 5.1 Gapps via a quick Google search.
Wipe factory/data reset in recovery before installing CM12.1 (unless you are already on a CM12.1 build).
Reboot into recovery and install ROM and gapps.

Known Issues:
LTE radio - Acts up at times requiring a reboot. Causes wakelocks
GPS sometimes it works, sometimes it doesn't. Reboot usually fixes it.
CAMERA - 720p recording fails, all other resolutions work well
USB wakelocks after removing USB cable, "USB Connected" pop-up doesn't go away.
OTG/keyboard dock doesn't work at all

Overall device is smooth and stable minus the above listed issues. I will continue to work on these but wanted to get some feedback on this so far as well. I'm open to assistance if anybody else has one of these and some talent and wants to help.


Huge thanks:
@invisiblek and the rest of the Samsung MSM8960 device maintainers, without there work to follow this would have never happened..

These build utilize the existing samsung 8960 device trees and the 3.4 d2 caf kernel hosted at CM github as well as the following:

It is lonely here but whatever, i'm still working on it in my spare time. Fixed camera in new build i just uploaded. Also BT is working, sort of....sometimes. Not sure whats going on with BT but i'll keep at it.

I have been waiting for this forever thank you so much. I was almost giving up on this tablet. Thank you for the hard work. I love me some lollipop.

I'm not as experienced as some others so this took 3 attempts I think...in between 3-4 month breaks to get the 3.4 kernel booting but I finally got it.

I've got GPS fixed and I'm close on USB. Its proper in windows I think but Linux connectivity is still giving me issues. I'll try to get a new build up in a few days with all that.

2/28 build is up now, GPS and USB should be proper. OTG/dock still not working but not a major concern for now.

The new update says 403 forbidden when trying to download?

Fixed, any issues or things not proper other than what ive mentioned please let me know

Is there a flashible zip for twrp 2.8?

Click to expand...

Click to collapse

No, I could likely make one though.

Use the did method outlined in the old recovery thread or cheat like I do and download "flashify" from market to flash recovery

This ROM is great. I installed peel ir remote app but it says this tab does not have ir blaster. It does have a ir blaster. Is that only a touchwiz app?

Click to expand...

Click to collapse

I doubt IR is working at all...that's on my list to test/debug.

USB is still a little wonky, the notifications never clear.

rippedwarrior69 said:

Oh OK that's cool. Thank you again for the hard work.

Just put up a fresh build, IR blaster seems to be working now.

For those who have tried this ROM, can anyone confirm whether or not wireless data is working? I don't have a vzw account to test with.

I can confirm that data is working. Thank you for breathing new life in this tablet
Edit. Had running for a full day and data works most of the time. A soft reboot fixes it though

If you wouldn't mind I'd like to see the logs when it craps out. I still have some hacks in place for debugging. When it acts up, reboot to recovery and grab the following:

/data/data/logcat.txt
/data/data/kmsg.text
/data/data/radio.txt

Oh and there is a newer recovery build and an updated build at the download link.

I'm dropping the "ALPHA" label at this point. Everything that should be working seems to be in order at this point and the builds are more than reasonably stable. I just uploaded a fresh build w/f2fs support on /data and /cache if anybody is interested in using that. Changing /data to f2fs will require a FULL factory reset and SDCARD wipe as sdcard is emulated on /data/media so be prepared to lose EVERYTHING. TWRP 2.8.5 is required if you wish to reformat anything as f2fs. Both are available at my codefire download link in the OP.

A few minor annoyances remain:
Charging is painfully slow.
USB OTG doesn't work at all.
Plugging USB to PC tends to create some nasty wakelocks.
LTE data is glitchy.
Keyboard dock support hasn't been brought in.
