Also OTG is supported by the kernel! If you use a OTG cable and put a mouse the mouse shows up on screen. Also a debug pull shows me below when I plug in my 32GB USB Stick.

I have a 64 gb SD card which I put some movies on it. I've watched some of them the other day, so they were there and working @ that time. I went to watch one today and the movie file name was there but the file size was zero? Appears that several files are listed but their size changed to zero.

Just curious if this is a common issue with android or if anyone else has encountered this on theirs tablet?

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
Weird, I couldn't quote you slicingtaco. Said invalid message I'd.

I have mp4/MPG movie files, each should be about 300 mb in size. I use MX Player Pro to watch them. I played a file the other day....no problem. I try to play one today and get an error "unable to play the movie". I open root explorer and navigate to the folder where the movies are stored. The movie file name is there but the file size has changed to zero. I tried using the Undelete app and the movie doesn't appear in the list of deleted files. I checked using ES File Explorer and the files exists but their sizes are zero. Only happened to movie files.

I've used the All in one tool app to clear history and cache. Wouldn't think it would nuke files.

Are 64gb cards supported. When 32gb cards first came out i ordered one for a device i had, a guy on a forum said he had one and it worked fine so going off his advice i orded the exact same card. This was when 32gb cards cost a butt load. The card was recognized by the device but once I filled it a bit over 16gb the data got corrupt. Try and fill it to about 32gb then add some more files see if the data corrupts. If that's not it then test the card on your PC.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
I think you might be correct. The tablet supports 32 gb but it does recognize 64 gb. I have the SD card partitioned 10 gb for Link2SD and the rest as storage. Out of 51 gb there is 20 gb free. So I think your right about corrupt data over 32 gb. I'll back up files to my PC then fill the card up just to see if it blows up.

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] slicingtaco:
I am surprised, MX Player can handle anything thrown at it.

What format was the file the other? On the same card? What file system is the card (FAT32, NTFS)? Is any other app using (reading from) the card? Try enabling S/W decoder (local)

No, clearing the cache and history wont remove the files, give that a try.

If not give Dice Player a shot.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
I've played all sorts of files with MX Player including VOB files without any issue. The files were all MP4's. The SD card is formatted Fat32. To my knowledge, no other app was accessing the SD card. All apps were closed. Just Root Explorer, which I used to click on the file name which launches MX Player. The problem isn't with the player. The problem is that files are mysteriously vanishing.

Other weird things I've experienced are Tablet UI stops responding and the touch screen is non-responsive forcing me to reboot, several apps randomly hang presenting the "wait or close" dialog, and random apps just magically disappear. The app is installed with its icon present inside the folders I created, I just used the app previously, then I try to use the app later I'm presented with the dialog "the app isn't installed". I use Plex and I sync movies to my tablet and I've had every single synced file vanish without a trace. The only thing I can say is that files seem to vanish after I completely reboot the tablet. I'm using the stripped ROM. Now I'm not blaming the ROM. Like my PC, I push hardware to their limits tinkering. Its just odd behavior.

I even tested the 32 gb limit theory. I turned off my tablet, pulled the SD card, used a card reader to back up data, then I filled my 64 gb SD up to 48 gb, then put it back and rebooted. The Diskusage app shows that the SD card has 16 gb left. I used Root Explorer to access the SD card, and directly played new movies that I put on it. No issues whatsoever. All files seem to be in tact. Although I go to use my Yahoo weather app and it magically isn't installed. Shrugs.

I too have had a couple of apps disappear as if they'd never been installed. However, I install all apps on the internal memory so I don't think it had anything to do with the µSD card. Weird indeed. :-\
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] tmoulder:
Are you sure your movies are actually gone? I tried using a couple of Move to SD-type apps at the outset, and they move the files off to another location on the SD card, and drop a sym-link in the original location. The stuff you are missing may just not be where you expected to find it.

Check your total SD card available space and see if the amount used is less than expected.

Just something to try :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] kngdmond:
The movies are definitely gone. When I pulled the SD card and checked on my PC, the file names were there but their file size was 0 MB. There were no symlinks. The files were legitimately placed on sdcard1 which at the time only had 24 gb used and did not exceed 32 gb total. Just for testing measures I filled the SD card, all but 16 gb, and there is no data corruption and movies play fine.

I did further research and others say there may have been a "hiccup" and somehow the Dalvik-cache got deleted. That doesn't explain the movies but it does for the disappearing apps, especially when this seems to occur after rebooting.

Others have said they had a similar issue and returning to stock fixed things. But I'm not going back.

Thanks for all the information xboxexpert and others.

No problems with the root or recovery, it's easy as cake, but I ran a search and didn't find any information regarding my situation.

Basically I've had the tablet since launch, but for some reason the back of the tablet feels a lot more flimsy than it did when I got it, and the bezel is 'clicky; like it's falling off. I'm thinking it's due to the heat of recharges loosening the back plastic casing, or maybe a bad production run. I don't know if anyone else has had that problem, but since I purchased the Wal-Mart replacement plan, I would like to replace it or get equivalent for it before it gets worse.

The problem is making it a completely 'clean' to stock OS. Technically, I've done that with the easy procedures in the original posts, the OS itself is totally stock. I'm worried about the Clockwork Mod installation though. Yeah, chances are, since it isn't that evident unless you hit Power+volume that no one would notice it when I sent it back. But, I'm worried they'll look for any excuse to not give me a replacement, I can see some joker saying "oh your bezel is falling off, but hey you rooted this, no exchange for you!"

Anyway, the tl;dr version is: is there an established procedure I can do to get rid of Clockwork Mod Recovery and make it as clean as stock as possible to send in for replacement? Any help is very much appreciated, thanks for all your information and work guys.

I don't know what to tell you to be honest. Have you ever thought of giving XE V2.2 ROM a shot and see if this mysterious problem still exists?

It's for a different older device. I know man i wan't source just as bad as you do.

You came and you are at the right place. In order to get a 100% stock for a warranty service/replacement you need three things that you can find right here.

Stock Untouched ROM

Stock Kernel

Stock Recovery

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] casinoroyale83:
Thanks! I didn't see the kernal there but now I've spotted it.

I've never actually flashed anything before, just used the simple steps in post 2 to root it, which a baby could do. I'm guessing I have to get into ADB/APK to do this flash right?

In my research, I've seen you need specific drivers for the tablet to recognize everything on the tablet and they're *usually* on the manufacturers website. I noticed they're not with Hisense, so I'm guessing there's a certain generic driver for this sort of thing. Also is there a generally accepted protocol to reflash a tablet with the ROM, kernal, and recovery I can use as a base to learn from?

Sorry, I know I'm fairly new at this, but I would like to learn - not just to get this ready - but for the future as well. I'm studying for my CompTIA A+ certification right now so I'm like a learning spounge right now, and like to put in the work to get things accomplished. :)
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] slicingtaco:
Yes those generic drivers are also as well found in the OP:

Thanks. My drivers are installed now, I'm not seeing a way in his .exe scripts to revert to stock OS with no Clockwork Mod Recovery on the system though, even though the zip contains stock_boot and stock_recovery

I'm downloading ADB now since I can't figure out a way to do it easily.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] xboxexpert:
If you have the scripts just boot to fastboot and use the post 1 to flash the stock recovery. You may want to actually flash the stock OS through clockwork first though and make sure it boots then flash recovery and boot.

fastboot flash boot stock_boot.bin

fastboot flash recovery stock_recovery.bin
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] casinoroyale83:
AWESOME thank you! I've never done this before, so it feels good to figure it all out. Always feels good to learn something that works, especially with command prompt. The only difference is, that it was an .img file instead of bin.

I'm guessing the stock boot of power button and volume down is 'Android System Recovery' is correct, because that's what it is now. I think I'm good to go to send it in now, right?

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] someguyatx:
Yes I definitely noticed my tablet rear panel is a bit more creaky than when I bought it back in June. Mine is typically in a case though so it does not bother me since the tablet functions perfectly otherwise. I consider this only negative thing about this tablet.

I did not get the Walmart plan because I read the details and you are not guaranteed to get the same model tablet as a replacement. Also dealing with Walmart on a tech item could possibly make me lose my mind. I seriously doubt anybody working at Walmart would have a clue if your tablet was rooted or anything else.
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] casinoroyale83:
I just called, actually they don't even do anything except forward you to the manufacturer if it's still within warranty. I'm not going to worry about it then since they're going to charge shipping and all that, guess I'll just wait around 7 months until the replacement plan kicks in.

Ad Hoc wifi tethering

I'd like to be able to tether my Sero 7 Pro to my phone, but it doesn't work in ad hoc mode. My understanding is that it's a Jellybean issue -- some say Google has deliberately crippled ad-hoc in 4.2. Anyway, two questions:

1. Has anyone figured out a way around this? Maybe found a working wpa_supplicant for this tablet?

2. Alternatively, can I flash any ICS ROMs on this tablet, like CM9, which supports ad-hoc wifi connections?

Sorry if these are noob questions. BTW, thanks Xbox for your incredible work on this device!!
[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] Cellular-Decay:
Hacking wpa_supplicant alone is no longer enough. Ad-Hoc has been disabled at the Kernel level in JB. Google sucks donkey balls! I really don't understand what their problem is with Ad-Hoc, but someone should start a class action law suit for advertising Android devices as WiFi capable when they are so severely crippled. It's like advertising a car with a V8 engine when only 4 cylinders actually function.

And it's not just a JB issue, Android has never supported Ad-Hoc, even though it is the #1 requested feature on their support site. It just got worse with JB because Google killed it at the Kernel level to prevent hacked wpa_supplicant files from enabling it.

And more bad news I'm afraid. Since Hisense has not released source code, there are no fully custom ROMs (only lightly tweaked ones), and there won't be until we get source. So basically, if Ad-Hoc is important to you, get a Nexus-7 (or something else that has CM ROMs available). Based on how long HS has been stalling, I don't expect to see source any time soon, if ever.

Another option would be to look at Asus tablets. I've read that Asus customizes their 'Droid OS to include popular features like Ad-Hoc support. Or... get an iPad (ouch!). Probably works on the Surface and other Win-8 tabs as well (haven't tried it - I'll try and remember to check that out next time we get one in the shop). I'm basically in the same boat as you, and as much as I like this tablet, it's just not very useful without a mobile Internet connection, so I'm seriously considering jumping ship.

Mine too. Doesn't really bug me.

Well, I'm also interested establishing an Ad Hoc connection from my phone to my Sero 7. Reason being, I still have an old Touch Pro 2 running WM 6.5, and Ad Hoc looks like the best bet available to this phone. I also have Sprint approved Phone as Modem, using either USB or Bluetooth, but I haven't had any luck connecting with those either. I am reluctant to upgrade the phone as it still serves my purposes, makes calls, shares unlimited internet with my laptop, lets me do rudimentary "semi" smart phone stuff, and only costs $30 a month.

If anyone has any ideas, Ad Hoc, or other on how to share my phones internet with the Sero 7, I would be most happy to hear them. Thank you.

[Hisense Sero 7 Pro ROMs, Kernels, Recoveries, & Ot] bast525:
Dunno how useful anyone will find this, but I figured I'd share a couple of "must have" apps that have made my Sero pro a much better experience, and thought I should recommend:

Tegra overclock

https://play.google.com/store/apps/details?id=com.tegraoverclock

Not because it can over clock the sero, but because it fixes an issue iI had with gaming. Basically, any time the sero would start to warm up a bit, performance would get horrible. I saw this on games like Nova 3 and Horn, graphically intensive games. They would get so choppy as to be unplayable. With the tegra over clock app, I found that the kernel has a three step "thermal guard" set up, and the first step was set at 45C... And cut the CPU speed in half! The app recommended that the speed not be throttled until about 70C. I changed to this and now have no performance issues. Only downside... The setting has to be redone after reboot. The app has other useful features as well... Such as disabling the annoying tegra prism screen dimmer that adjusts brightness even when auto brightness is turned off (tell me I'm the only person who notices this??) Also most of the standard stuff found in most kernel tweaker apps. Very good app anyways and regular updates from Dev too.

Folder Mount

https://play.google.com/store/apps/details?id=com.devasque.fmount

An apps2sd type app but much better. Folder mount can link any folder on the built in storage to any folder on the SD card. ANY folder. It can create the folders for you and move the files for you. So easy to use. It has an app analyzer which will show you the apps that it can automatically move arranged in file size order. Very user friendly automation but again very flexible if you want to create specific links yourself. I have more Gameloft games installed now than could ever have fit on the seros 5.5 gigs of internal storage, and still have 3.5 gigs free. Also constantly updated by the Dev. I wouldn't have kept the sero if not for this app...

GMD Auto Hide Soft Keys

https://play.google.com/store/apps/details?id=com.gmd.hidesoftkeys

Frees up space on the screen by hiding the softkeys when you don't need them. Great for gaming. Also gets rid of the screenshot button for this who want to stay on stock phone ui. Lots of configuration options.

Anyways, thought I would share... Too bad this will get buried quickly... Come on xda give us a dedicated forum!
