Pipo U9T RileyROM 1.0 KitKat

[rrileypm]

This ROM is based on Pipo KitKat firmware dated 5/9/2014.

Instructions on flashing this ROM are located in the First Time User's Guide.pdf file in the zip file.

I don't own a U9T tablet, but I've read that it was originally released with Jellybean firmware...so this is the first KitKat release for this tablet. Please keep in mind that going from Jellybean to KitKat involves some major changes in the partitions...and the loader MUST BE CHECKED when you flash this ROM. Otherwise, you will have a brick on your hands.

If you are new to the Pipo forums, please browse the main Pipo forum for tips and answers to the questions you might have. By all means, though...please feel free to post your questions and comments about this ROM. It's the Freaktab members who continue to provide ideas on ways to improve this firmware.

RileyROM Features:

Full Root with SuperSU
Full Debloat
Google Play Store fixes
English as default language, but all Android languages are supported
Busybox commands added for init.d support
Ext4 File system
2, 4, 6, 8 and 12gb user app space (the default parameter is 4gb)
KO files added for VPN support
Boot animation by me
Flash Tool by Finless
Reboot app by Petrus
TWRP Recovery by Abdul_Pt
First Time User's Guide by Pr0xZen

I would love to have one of these tablets to test with, in order to provide continued support. So please consider a donation, and I can order one.

If this ROM makes a difference for you, please consider a donation to support future RileyROM's here at Freaktab.com Donate!!! The Summer 2014 releases are here, so I need to update my testing equipment very soon.

Does this have cifs support?

edit nm:
cifs modules cause kernel panic when mounting a folder..

insmod auth_rpcgss , lockd, sunrpc , nfs
nfs not working <4>[ 581.037097] nfs: Unknown symbol dns_query (err 0)


(also my tablet shipped with kitkat installed, as well as all other reviews I've seen , and I could not find a JB firmware for it so dunno if it ever had jellybean )

[rrileypm]

All of the modules were added to this ROM and insmod was done in the boot.img.

They should work, unless a newer version is required for the provided kernel. I'm using the most up to date modules.

yeah they insmod fine (bsides for nfs.ko, tun.ko tun: exports duplicate symbol tun_get_socket (owned by kernel) I guess pipo added that builtin.),

root@rk3188:/mnt/internal_sd # lsmod
ntfs 194603 0 - Live 0x00000000
sunrpc 174640 0 - Live 0x00000000
md4 3319 0 - Live 0x00000000
cifs 245765 0 - Live 0x00000000

mali 152580 15 - Live 0x00000000
ump 30472 13 mali, Live 0x00000000

no kernel panics, but as soon as you try to use the busybox mount -t cifs //192.168.1.1/share /mnt/sdcard/cifs/ -o username=username,password=password,ro

the system will freeze and reboot, I have tried to strace and everything but couldn't find anything useful, maybe the modules are fine, it even could be related to kitkat or busybox .

strace

^ reboots

even tailing /proc/kmsg doesn't give any details about the crash

(btw TTWRP (preinstall/recovery.img) is not being flashed, since flash_tool doesnt work on this tablet for some reason it doesn't find the recovery partition, manually trying to flash the recovery fails too, black screen.
abdul_pt tried to make an updated one but so far it only gets the the teamwin logo dunno whats up with this tablet :|.)

anyways I dunno, let me know if you need any information on this tablet, I have even tried compiling the kernel modules myself using various toolkits and from 4 different rk3188 kernel sources while most insmod fine I cannot get the mount funtion to work without it causing a reboot, I come from android 4.2.2 so I am not overly familiar with kitkat and selinux maybe I am missing a step.

[otyg]

ok I compile my own modules after a few hours of testing and have come up with a successful result I will post the modules in a few hours

so far I have cifs working , still need to test nfs

edit
Issues:
NFS modules insmod without errors, but I get a reboot when using mount,

cifs is working great but I can only access the mounts when mounting through shell, using cifs manager is not mounting them for some reason will try to figure it out, might be kitkat restricting it.
ok looks like kitkat sandboxes apps so only the app that mounted the share can access it, unless it was mounted by adb ...anyone know a way around this?

[rrileypm]

Hey, that's some great work so far!!!!!!

When you come up with a solution, would you be willing to share those new modules with me? I'll credit you in my ROM releases.

Ok I uploaded the cifs module here

http://www.mediafire.com/download/ndtdfdtkn7c97de/u9t-cifs-3.0.36.rar

Just need to figure out a away around kitkit's restrictive mounting or how to disable it

The nfs module insmods but I am still unable to get it to mount without a kernel panic so I'll try and figure that one out next

[abdul_pt]

Have you checked SElinux state ? Have you tried setting it to permissive, if it isn't already.

I checked with getenforce and it said it was disabled, looking on some xda threads there are a few source patches but look complicated and involve patching the android source and init.rc

TWRP Recovery by Abdul_Pt - not working loader. And when the substitution file is not loaded firmware, loaded only recovery

[rrileypm]

1. Make sure you have a good USB connection. Use the cable provided with the tablet as the best choice.
2. Make sure you have actually selected the TWRP file in the flash tool. It could be that you've just re-flashed the stock recovery.

Those two items would be the only reason you still have stock recovery on your tablet.

[don666]

recovery taken from the archive you posted. The firmware is successfully, but there is a standard recovery, icon lying Android
when the substitution of recovery comes from a different source from the official site, he does not see the partitions on the tablet and not loading the firmware

[rrileypm]

Try flashing this version of TWRP:

http://www.freak-tab.de/abdul_pt/TWRP/Generic/TWRP_1920x1200_rk31xx_KK.img

From the flash tool...uncheck all items except recovery and browse the recovery line (little box to the right of recovery.img) to wherever you saved this file. Flash it without erasing IDB.
