The drive has to be formatted FAT32 or ext4 - this kernel doesn't support NTFS or exFAT. Also, does the hard drive have its own power supply? I'd be surprised if the tablet could supply enough power.

When you wiped your /data partition, you deleted the system's battery stats which it uses to generate accurate battery usage info. You really shouldn't put too much faith in the battery readings until you've fully charged it then run it down almost all the way at least once. Once it has rebuilt its database, the readings will be more meaningful.

To prolong battery life, turn off NFC, GPS, Bluetooth and WiFi when you're not using them (GravityBox makes this pretty easy to do since there's a Quick Settings tile for each one). And of course, kill the screen whenever possible.

BTW... speaking of USB-OTG devices and charging the battery... Someone sent me a link to a kernel patch which enables you to charge the tablet while using OTG. Using it requires a special Y-cable so both the device and the charger can be attached, plus it may require a small app to turn the feature on and off. I'll add this the next time I build a new kernel.

This sounds fantastic - Being able to supply power while using USB could have a lot of applications. Know what cable should be used?

Downloaded and flashed. Works great. Thanks.

If I reformat with the the dopa-v2.5 Phil's touch to fix encryption, could I then switch back to TWRP?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] paratwa53:
Very cool that you are continuing to support this great device! And doing the very best work of anyone!

A bit more from that prior link I posted about OTG for our powerchip

+ TPS80031/ TPS80032 Fully Integrated Power Management with Power + Path and Battery Charger. The device provides five configurable + step-down converters, 11 general purpose LDOs, USB OTG Module, + ADC, RTC, 2 PWM, System Voltage Regulator/Battery Charger with + Power Path from USB, 32K clock generator.

I hope this turns out to be the holy grail for OTG power management. But I really have no freakin idea.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
The stuff you found are various versions of the driver for the power controller chip. They are newer than the version that Hisense used (and modified to suit their circuit design) and are better thought out but functionally the same. The references to OTG pertain to using the chip to supply power to an attached USB peripheral, not to drawing power when an OTG device is attached.

Now, to address your concerns: the issue here is not one of hardware capabilities - pretty much everything that we need to know about OTG charging is already known. Rather, the issue is a design decision: how much of the available power should be allocated to the OTG peripheral(s) and how much should be dedicated to the tablet. Before the kernel patch, 100% of the power went to the peripheral; now, 500ma out of a supposed 2000ma is redirected to the tablet.

I don't doubt that the amount currently reserved for peripherals exceeds any real-world needs, so I have no problem with giving the tablet more power. I just want to do it prudently so the peripherals get what they need, the tablet doesn't

loose

charge, and the power supply isn't over-taxed.

If you don't expect to encrypt your tablet, there's little reason to bother with that reformat. Beyond that, TWRP should be perfectly OK (if not. let us know).
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] paratwa53:
You sure know how to turn a phrase!

Whatever you can do I know will be your best. I should be getting my new Y cable in a few days and I will be better able to see if the battery will stay charged running HDMI and a USB mouse. Running HDMI is a battery killer.

Like I said before, my hopes are to be able to use my Sero as a HTPC. This means having it running for hours on end. But if it does not work, I guess I can always find another solution.

Thanks again for your excellent work!

Don't know if I'll ever need to encrypt. Just thinking I should keep that option open. Guess I'll worry about it if the need ever arises.

I've been using davepmer's SELinux/F2FS compatible TWRP build with your AOSP444 ROM for a week or so and it's been working great. Reformatted cache and data to F2FS and restored my data and it's all good. Upgraded from your v2.1 to the beta 2.5 (and F2FS), and then to the 2.5 final without incident.

Thanks again for all your efforts!

About to go down the dopa 2.5 path, I have a semi brand new pro that hasn't been played with yet, so I need to root but I usually only run linux and most of the rooting guides are all using winblows, is there any root options that do not require winblows?

I do ahve a couple of machines that I can dual boot if I need to but thought I would ask.

Which gapps package are folks using and which one works the best?

Thanks in advance :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ziddey:
Bootloader is not locked. You should be able to boot into fastboot by holding power+volup (might need usb cable disconnected) and flash a custom recovery and go from there. No need for any windows-based rootkits. If you want the whole suite of gapps, go with the fat google stock package pa gapps-- http://xdaforums.com/showthread.php?t=2397942

Be aware that you can't flash /system as f2fs if going this route since there won't be enough space.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:
Thanks for the reply but isn't fastboot a winblows application? Trying to find someone that has done it from linux to see what the steps were, I have download one of the root packages and I see fastboot.exe and adb, maybe I could use adb. Is there anything I need to do in order to boot into fastboot?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Fastboot is cross platform. It's included in the Android SDK so download the Linux version of that and you'll find a fastboot executable for Linux.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:
Yup I have figured that out, I have adb loaded and fastboot and now have my desktop seeing the device, wondering if I should document this, or maybe everyone already knows how to do it, lol, or most folks are not running linux ;)

Now I am trying to figure out how to transfer some files and see what I can do and not brick things... Looking at some of the fastboot commands, will this install for recovery?

adb testing

adb reboot (reboot the tablet)

adb reboot bootloader ( boots into fastboot)

So now the $$ question is will this load philz touch recovery

fastboot flash recovery /(path_to_rom)/philz.img

Anyone have any suggestions?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] ziddey:
You got it. Afterwards, you'll need to immediately boot into recovery, or else the stock rom boot process will restore the stock recovery. From a powered off state, the button combo is then pwr+voldn.

Or you may be able to fastboot boot recovery.img to send a temporary instance and boot that.

From recovery, you may wish to make a dump of the stock rom. You can use adb to gain shell access with root:

# dd if=/dev/block/platform/sdhci-tegra.3/by-name/APP of=/path/to/external/sd/system.img
# dd if=/dev/block/platform/sdhci-tegra.3/by-name/LNX of=/path/to/external/sd/boot.img

I'm not in recovery currently to know what the sd card path is.. Or you can use the internal "sd" as well. But do note that if you format the whole data partition (say you convert to f2fs), it will wipe it, so you'd have to take the extra step to pull it (e.g. adb pull /path/to/system.img). And make sure it actually successfully pulls it. I seem to perpetually have issues with adb file transfers.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:
Well I have been able to fastboot into philsz.img and side load the via adb but Imust be doing something wrong since I cannot boot back into recovery after I exit.

When I exit it comes up and asks a couple of questions and I have answered no to both of them, one of them is concerning root access and not sure about the other one..

---------- Post added at 08:45 PM ---------- Previous post was at 08:34 PM ----------

Well I atleast have recovery loading up, Here is what I did:

adb reboot bootloader

sudo fastboot boot philz.img

That booted the philz.img and from there I went and installed the zip from the side load option and then loaded it via adb

Now holding the power and vol- I can enter into recovery - Sweet

Now trying to figure out if I want to wait for my replacement sd card or just load up via adb, adb is pretty sweet once you get it up and working :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
I'd wait for the replacement SD card. (let me guess, SanDisk brand card, reads 0 bytes?) Pushing such a large file like a ROM through adb is very finicky.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:
Transcend, for some reason when trying to partition and format under gparted, it just kept messing up, tried multiple computers and different carriers, something was not happy, so I ordered a samsung brand...

Yeah not sure if i can wait 2 days, I have been sitting on the pro for over a month and just found some time to play...uggh oh well...

I still need to figure out which gapps to roll with but I like philz recovery, looks very nice :)

Thanks everyone for the help to get me going :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
I use the 0day Micro Modular PA GApps. Saves a lot of space in the /system partition and doesn't have a bunch of unnecessary clutter.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:
Well I thought what the heck and loaded via adb, went with the micro package and she booted right up. I do notice that most of the apps no longer work, the stock ones that is, so I am just uninstalling them and looks like I can load up whatever I want. Mine is only an 8g version so I will probably wait for my sd card to come in so I can load link2sd and set that up and then start installing stuff....

Wooot thanks everyone for the help and dolorespark for what looks to be a good and stable rom :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Cellular-Decay:
I've always had good luck with Transcend. Odd.

There is no reason to format /system F2FS since it is read only and Flash Friendly File System's claim to fame is faster write performance. Just leave /system ext4 and use F2FS on /data (and cache if you want). That way you can install any GAPPS package you want.

No offence to Phill, but phillz-touch is just a kluged version of CWM (a text/menu based recovery with crude touch controls tacked on). Team Win Recovery Project is the new standard in Android recovery. XDA developer davepmer has an SELinix and F2FS compatible build of TWRP for the Sero 7 Pro. You should check that out. If you need to encrypt your /data partition you'll need to stick with the dopa-2.5 phillz-touch. Otherwise I'd recommend using Dave's TWRP with Dolores Park's AOSP444-2.5 ROM. That's the combo I'm using, and it rocks!

Assuming you are using a recent Debian/Ubuntu flavor of Linux, all you need to do to install ADB & Fastboot is open a terminal and enter,

sudo apt-get install android-tools-adb

and

sudo apt-get install android-tools-fastboot

You don't need the entire SDK to flash a recovery image.

Yup, thanks I have things up and running was able to piece things together and have booted its working...I hit the thanks buttons and even threw some coin to Dolorespark for the rom....since he is supporting it and not hisense. :cool:

Just need to figure out now where to turn of the notification noise when I get an email...
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] paratwa53:
I went with the light version of gapps, it gave me playstore so that I was able to get everything else I needed without all the crap that you can install separately if you want it. I liked philz as well.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Cellular-Decay:
Glad you got things up and running. This tablet really is pretty awesome! Even a year later it can still hold its own.

I just don't understand why it has been largely ignored by the mainstream Android development community. No official CWM or TWRP builds. No official support from CM. Heck, we can't even get our own space here on the XDA forums. If it wasn't for the kind souls here in these threads we'd still be stuck with the factory ROM.

So, thanks again to all who contribute to S7Pro developement!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] paratwa53:
I think it's because it's not a "expensive" device. It does not have the bling factor of how much it cost.

If it's cheap, can't be worth my time mentality. :mad:

I also want to say thanks to everyone that ignored that and realized what a great device we had, starting with Xboxexpert who gave us our first taste of customization and continuing with dolorespark, davepmer, randomblame and everyone else that has developed and helped trouble shoot! Thank you all for your time, expertise and sharing your knowledge!

Did you happen to do a backup of /data as you mentioned in an earlier posting? I believe there are some Nvidia configuration files I'd love to get hold of.

As to using the stock apps... The old method of creating symlinks in /data/app that point at the actual .apk's in /thirdparty no longer works. After getting past an SELinux issue, I discovered that the name of the .dex file in dalvik-cache doesn't match what the dalvik runtime expects. I'll have to modify some code to get them in sync. Meanwhile, if you just have to have the Sam's Club app :), use a file manager to navigate to /thirdparty, then have the file manager install it (in ESExplorer, tapping on it brings up the app installer by default).
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Gster09:
Speaking of /system and f2fs, I ran into something when playing around with the beta 2.5v so I don't know if it's been addressed in the latest release... Please forgive me if it has: If /system is formatted as f2fs, the Nexus 7 spoof won't flash. Silly I know since /system is usually read-only and not really in need of an f2fs format, but that's what I experienced.

I have a backup of my tablet (all partitions) that I labeled "Totally Stock." I made it with CWM back in July of last year and I honestly can't recall if I'd already logged into my google account and set-up anything when I backed it up. Still, other than the recovery image, it should be all stock. Is there a way I can send you what you need without having to reflash the whole thing?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bishoptf:

To follow up on my earlier post; I've done some digging in the backup files, and I believe these to be the contents of the /data partition. Any configuration files you need are at your disposal, just let me know.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
Sorry to take so long responding but I was out of town (death in the family)...

None of the images that he labelled "stock" are anything of the sort - they are all polluted with various mods.

Basically, it didn't work because it wasn't supposed to. That spoof was for v2.1 which was ext4 only and didn't know how to mount an f2fs partition. The spoof for v2.5 _should_ work fine.

Problem is that I'm not exactly sure what files and folders I'm looking for. I gather that screenshot was from some app that displays the contents of an archive. If your software permits, could you make a

copy

of the archive, then delete the dalvik-cache folder from the copy? If so, that should bring the whole thing down to a manageable size. If you don't have some place to upload the copy to, I can provide one. Send me a PM and we can make whatever arrangements are needed. Thanks!

First, my thanks to all who offered to send me the contents of their /data partition (or in one case, the tablet itself) - in particular, Gster09 who had everything ready within 10 minutes of my last posting.

I had assumed that the /data partition would contain configuration files for some Nvidia-specific programs, in particular nvcpud and NVCplSvc. Sad to say, it actually had nothing of value. Oh well, now we know we haven't been missing anything...

She said she sees the same thing when restarting the table, but I have not seen it so I'm not sure if that's actually the case. Anybody else experience the camera app crashing?

[UPDATE] AOSP 4.4.4_r2 DoPa v2.51

I've just released a bug-fix update, v2.51. Please see the initial posting for links.

The only users who

need

this update are those who plan to (or already did) reformat their /thirdparty or /mnt/modem partitions using f2fs . For all others, it is entirely optional.

If you do decide to upgrade,

only

install a new boot.img and the PhilZ Touch update; the ROM itself is unchanged.

Bugs Fixed

* if you reformatted either /thirdparty or /mnt/modem using F2FS, your "internal SDcard" would disappear, and PlayStore would crash when you tried to download an app

* using PhilZ Touch to reformat either /thirdparty or /mnt/modem using EXT4 would fail because SELinux info was missing for those partitions

My apologies for any inconvenience this may have caused...
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] jerbear294:
Thanks for the update! Do you have plans to update the ROM to Android L when it is released?
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] dolorespark:
More than likely - though I'm not sitting on the edge of my chair waiting for the code drop. If the final product is anything like the master branch, I should have a leg up because I've already done the tedious, time-consuming stuff: getting SELinux permissions set up for the device-specific parts of our ROM. The next version will be locked-down tight and everything will require the appropriate permissions to do anything. If they're missing or incorrect, stuff won't work. Hopefully, this prep work will save a week or two in getting out our version of the final product.
