Well I know, that's a positive but I just wanna be sure that if I flashed this on a MS769 it won't brick the phone and refuse to boot it lol. I also tried inserting his MetroPCS sim into my T-Mobile P769 and it didn't recognize it so I didn't want to risk damaging his only phone hence why I'm trying to find out first. Thank you though for helping me out!

my SD card isn't being mounted, when I try opening my camera or gallery app they crash with the message "Unfortunately, Camera/Gallery has stopped", and I'm constantly pestered by the "unfortunately google play services has stopped" if there are any known fixes or other solutions for these problems I would really appreciate them!
I had the SD card problem before and idk how I fixed the problem but either it fixes itself, have to wipe cache, or reflash the ROM
The camera one, idk about that, I haven't had that problem..
For Google Play services, look down
FIX FOR GOOGLE PLAY SERVICES PROBLEMS:
1. Go to Settings -> Privacy -> Privacy Guard;
2. Tap on the three points on the top left and select Advanced in the menu;
3. Search for the Location Section tab, and tap on Google Play Services;
4. On Coarse Location, change from -Allowed- to -Ignored-;
5. Open the Play Store and log in to your account;
6. Exit the Play Store.

ROM Bugs and Glitches

hmmm well I guess I'll try these the next time I can access them. Unfortunately, one of my phones got locked with a security error and the other is trapped in a boot loop so im probably going to need to fix then reflash both of them when I have time XD. Idk I was really hopeful that this rom would bring new life to these phones but i'm still having a slew of issues :( I hope I can get them fixed and have these 2 phones as good and ready back-ups.

Hi Micheat, have you tried for the device in boot looping, start in twrp through the fastboot command "fastboot boot recovery your_twrp_file.img" and re-flash both the recovery and the ROM? remember to make everyone wipe system, data, cache and dalvik before doing the twrp flash!

I had the problem that the phone never got recognized again in Fastboot Mode after updating to Win8.1 and later Win 10. On my Desktop and Netbook, which stayed on Win7 until the release of Ten.
ADB worked, but the interesting functions need a Reboot -Fastboot command via ADB to perform.
So in case of trouble it was always unbricking in Download Mode, with a non-rooted stock phone as result, then rooting stock via Kingo Root to be able to install TWRP, then you can restore your last TWRP backup.

So, since you're having problems with Windows 8.1 or Win 10, have you tried to install a Virtual Machine, and install Win 7 with the related drivers and software?

There is also another possibility, also use linux, either with Virtual Machine or with cd boot or usb boot! and then install the ADB and FASTBOOT drivers! [emoji6] as you can see here!

My P760 was supposed to become a mobile AP after i switched to a Galaxy S5, but this very rom(or was there already a Cm13?) seems to have damaged my phone. I could never authenticate with 5ghz APs and standby drain was about 50%/day. This remained after stock recovery and then, as the phone was no longer the daily driver, i found out that the drain remained in soft-off state! The phone definitely shut down and powered on correctly, but was using up half of the battery per day. Wifi/BT controller not switching off, i presume. I got a new battery and the drain only stopped as long as the battery was outside the phone, so the whole crap went outside, in the trashcan.
So especially users of the p760, check this out. Edwin Mocq had a different model, which supposedly won't misbehave.

Boot Loop

Hi Micheat, have you tried for the device in boot looping, start in twrp through the fastboot command "fastboot boot recovery your_twrp_file.img" and re-flash both the recovery and the ROM? remember to make everyone wipe system, data, cache and dalvik before doing the twrp flash!

I can't remember if I was able to boot it into TWRP at all while it was boot looping, I'm not really aware of what fastboot is but any info would help. But yes originally I'm pretty sure I had cleared all of its data before flashing but I'm not sure as to why it began boot looping.

as for fastboot and ADB drivers, you can see something here on how to install everything then to use and know the commands you can search on the ocean of google, you find them so much! The problem of bootlooping is the fact that often the boot files are not found or unrecognized during this phase, and every time it comes back to look for them, so the program comes back and reboots all over again infinitely!

I also remember the issue(probably cured by the latest TWRP) that the phone will brick when trying to access TWRP during power-on or restart. TWRP could only be accessed from within Android, so you could make backups and restore them after the lenghty unbricking procedure.

Enable Root, Install Kernel Auditor, Slow the CPU down to 800 on the high end, 200 on the low end and try On Demand Governor.
Slow it down to 600 if you have to. Then after a day or two of running it, bump it up a notch and see how it goes.
The Rom has a default clock of 1350 which is overclocked from the stock 1008. Mine Flash Crashes pretty quick at 1350.
Running it at 800 is actually kind of nice on the battery consumption too. Best of luck!

any otg support or kernel panic fixes pls i need it....

    New build is up! I messed media codecs trying to fix the camera and now media recording is broken. But front camera works now and I will fix media codecs ASAP. Vibrator is working too.

    For those having issues with SuperSu I recommend to use Privacy Guard. It allows you to manage different permissions of apps, including root access. Enable root in developers options and use Privacy Guard to manage root access. It works great for me.

    Next build with fixed media codecs will be up later.
