[ROM][P75xx][JB][4.2.2] CyanogenMod 10.1 Nightly Discussions

Can't you just activate the Hotspot feature on your phone (if it had one ofcourse)? That way you can just let the tablet use the phone's data connection on the tablet with wifi. Super easy.

Sent from my Z1 Compact

I didn't want to run down the battery on the phone. But I just found out that the bluetooth tether uses much less power. So I am going to do that. Thanks for the help.

    At pershoots request, here is the official nightly discussion thread. I will be updating this with information that I find and users posts that are helpful. REMEMBER: THIS IS A WORK IN PROGRESS SO ALWAYS READ THE THREE POST FOR UPDATED INFORMATION

    CyanogenMod 10.1 is a free, community built distribution of Android 4.2 (Jelly Bean) which greatly extends the capabilities of your tablet.
    New CM Wiki page! http://wiki.cyanogenmod.org/index.php?title=Main_Page
    New CM Documention! http://wiki.cyanogenmod.org/index.php?title=Documentation


    Usual CM disclaimers:
     * Your warranty is now void.
     * I am not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at me for messing up your device, I will laugh at you.

    Known Issues (copied from droidbasement):
    -A random flicker (it’s faint and fast) can be observed occasionally/infrequently. If this becomes a nuisance to you, you can try to alleviate this by selecting ‘Disable HW overlays’ in Developer Settings. This does not survive a reboot (must be selected on every boot) and impacts swiping motion (it slows it down) in Trebuchet (the Launcher).
    -P4*: A 720P recording, when played back, will have artifacts in the upper section of the image. Also when launching the recorded video for the first time, you will encounter a bit of a delay before it launches.
    -P4*:If you use the standard GAPPS (from goo), the keyboard will close if typed on for 2 or 3 letters quickly in succession, if you use Google Search, Messaging and/or Gtalk (there could be more). This is a GAPPS library issue. Install a third party keyboard (Swiftkey 3 works ok) and switch to it. This does not affect Browser, System, etc (stock KB works fine there). The GAPPS from wingray don’t appear to exhibit this behavior from brief feedback (make sure your system is cleaned out using the latest recovery (format system), prior to installing the rom and gapps if you had the set from goo installed prior (it has also been reported that data needed to be wiped as well to rid of the residuals)): http://forum.xda-developers.com/showpost.php?p=35825009&postcount=3553

    Install Instructions: IMPORTANT TO SEE READ ME IN POST #2 It will save you a lot of headaches when upgrading or updating your Tablet.

    1) Install the latest CWM (see 1st post for more info)

    2) Install ICS bootloaders (1st post) *People who flashed an ICS custom ROM coming from HoneyComb (3.1) do not have the correct bootloaders.

    3) Boot into CWM and flash CM10.1 (Please see READ ME in post #2 for more information)

    4) Flash gapps-jb-20130120-P75xx.zip (see 1st post for download)

    5) Reboot

    pershoot has stated before: "best to wipe as some experience lag with multi user." and "if you get any latency/ bizarro behavior, wipe"


    Want Adobe Flash on your Jellybean Tab? (update 05/21/13) New version is (
    Check out the latest download here: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html Scroll to Flash Player for Android 4.0 archives and download most current ( *Note: Flash is not supported in Jelly Bean, no support given in this thread as well.

    Need Developer options and Performance tabs?
    Go to settings>About tablet and start tapping Build number until it says your a Dev.

    I am getting sudden reboots or freezes?
    Not all tablets are created equal, if you are experiencing sudden reboots after Overclocking, reset your options back to default.

    I am still rebooting or freezing? :(
    Do a full wipe and DO NOT install anything. If the tablet is not rebooting or freezing, install your apps one at a time to isolate the cause. If you are using Titanium Backup, DO NOT RESTORE DATA FOR SYSTEM APPS.

    I get Force Closes (FC) when I launch ____ app?
    Try clearing data for the application by going Settings>Apps and locate the app and select Clear Data.

    How can I increase Launcher performance?
    Enable wallpaper hack (Settings> Launcher>Homescreen) and select Wallpaper quick render to boost home UI response (when using a static wallpaper).

    Once I am on CM10.1, do I need to continue getting my updates at get.cm?
    No, you can update future nightly builds by going to Settings>About tablet>CyanogenMod updates. Once there, change Update types to "New Versions (incl. Nightlies)" *NOTE: Pay attention to the file name, you might occasionally see CM 9 or 10 in the list, DO NOT FLASH!

    Can I enable Voice Calling on my tablet?
    At this time, the framework has the hook enabled to allow for users to work on the feature. IT IS 100% UNSUPPORTED at this time because it requires you to flash modems which is a deviation from the recommended setup.

    I flashed ___ from another___ thread, now ___ this stopped working?
    Wipe data and flash CM 10.1 from get.cm, does this issue still happen? If so, post logcat... if not, seek support from the thread you flashed the file from.

    I HATE the new layout with the navigation keys in the middle, can I move it?
    At this time, the nav keys in the middle is the design. Who knows, CM Team might change this in future builds.

    OH NO! Where did my previous CWM backup go?
    4.2. changed the file structure on how internal storage is viewed. Data on the internal/fake sdcard will go to 0/ (i.e. /sdcard/0/; /data/media/0/) (both are the same thing).
    Since the internal storage is emulated, it is setup now (using file explorer like ES) /mnt/shell/emulated then you will see /0/; /legacy/; /obb/; and /clockworkmod/. Copy clockwordmod folder to your PC and if you need to, flash back to old ROM with old CWM and then move the backup back to /sdcard and then restore.
    Using the latest recovery, to find /sdcard while in recovery, you will need to adb to /data/media/. *Note: Make sure to have a copy on your PC, I ran out of space before restoring since it is all in the /data.

    Hey! Did you see the easter eggs!!
    So not only is there an easter egg when you press the Android version and long press on the jellybean, but if you hit CyanogenMod version, CM planted one too. But did you know that by doing the easter egg and long pressing on the jellybean, you unlock another one! Go to Daydreams under Display in settings and you will see BeanFlinger!

    My sound is really low or really high when I am using headphones!
    If you are having really low or high volumes while listening with headphones, I recommend Voodoo Sound from Supercurio in the Play Store (Link). This allows you to take control of your volume and change it to your preferences.

    I see cm-10.1-xxxxxxxxx-UNOFFICIAL-p4xxxx.zip on Droidbasement, what's the difference between droidbasement builds and nightlies?
    The UNOFFICIAL builds on droidbasement are experimental builds compiled by pershoot for testing. It is recommended to flash the nightly builds unless specifically asked to test an unofficial build.
    READ ME:

    #If using 4.2.2 and want to roll back to 4.2.1 (last build is Feb 13th), you will need to do a full wipe to move backwards or you will bootloop. (update 02/19/13)

    #PSA from CyanogenMod team: https://plus.google.com/+CyanogenMod/posts/M2pVM7Y6MTq (update 02/19/13)
    ADB Whitelist

    As of the Android 4.2.2 update, when you connect your phone to a computer, you are presented with your computer's RSA key fingerprint to open the adb connection. You also have the ability to permanently trust the computer, so you don't have to repeat this step upon every re-connect.

    In order for this to work, you must be on the latest SDK which will grant you an updated 'adb' binary.

    We will not be introducing any functionality to sidestep this default security, so if you don't update, you will lose the ability to access the device using adb.

    # CM 10.1 is based on Android 4.2.1. Any and all proprietary applications that you have installed outside of CM should be updated to their 4.2.1 counterparts. Do not use the 4.1 versions of proprietary applications, else you will experience difficulties.

    # Do not use the CyanogenMod Updater to go from 10.0 to 10.1. While you will have a functional rom, due to the 1st bullet point, you will be left without your proprietary applications and their data. We highly suggest performing the initial install manually via recovery (flashing CM and your addons). Once you are on 10.1, you can use the CM Updater as per normal.

    # You do not need to wipe when updating to 10.1 if coming from an earlier CM version. However, as we mentioned in the weekend's PSA, users updating (instead of wiping) will experience a conflict in the application data for the Clock app. You are advised to clear this apps data on first boot of 10.1.

    # Another item to note is that the support for the 10.0 feature that allowed for an expanded number of targets on the pattern lockscreen is not in 10.1. If you use this lockscreen, disable it before updating from 10.0.

    # Finally, we always advise that you create a backup before any update. Do note, however, that due to Android 4.2 changes to support multi-user mode, your backups will automatically be transferred to /sdcard/0/[backup folder]. Remember this when attempting to restore 10.0. Credit to post from CyanogenMOD team (G+ https://plus.google.com/+CyanogenMod/posts/9X561GFMxL5)

    Coming from Samsung ICS ROM (custom or not) requires a FULL WIPE (Wipe Data, Cache, and Dalvik Cache) If you do not WIPE you will get a bootloop.

    From droidbasement:
    GT-P7500 (p4), GT-P7510 (p4wifi), SCH-I905 (p4vzw) and SGH-T859 (p4tmo)
    -For P4VZW: You must be on stock ICS (and it’s modem) before flashing to this build, for LTE functionality
    -For P4WIFI UK: You must be on the US ICS bootloader (odin .tar.md5 inside the .zip in the folder), otherwise you may incur a rolling screen
    -For P4: You must be on the UK ICS bootloader (odin .tar.md5 from AUS inside the folder), otherwise you may incur a rolling screen.
    -For P4*: You must be on the ICS modem for best results.


    Getting a logcat:

    1) Make sure ADB is installed (http://developer.android.com/sdk/index.html)

    2) Open Command Prompt

    3) adb logcat -d > logcat.txt

    4) Locate the logcat and upload to xda
    all, im working on bringing in a new wifi driver which should solve numerous issues and add some more functionality.

    just need to solve one last issue with it (speed is capped when using it on this device).

    once that is sorted (if can be done in a timely manner), then ill put out tests for all devices to ensure it works well in various scenarios.
    sorry all, i've been hella busy at work and also been feeling under the weather as of late.

    will get back to this when i can (have some more things i wanted to do).
