Viewpad 7 - how to root? - General Questions and Answers

How to root Viewpad 7?
Anybody suceeded?

Ok,
Use SuperOneClick, just make sure to click 'run as admin' if win7. That was were I screwed up.

In case you have issues here is a step by step:
a) Download the latest version of Super One Click (currently 1.6.5).
b) Place your Android device into debugging mode, and connect to computer.
c) Right-click the Super One Click executable and select 'Run As Administrator'.
d) At program launch select 'rageagainstthecage' exploit method, then select 'Root'.
e) If there is no activity for more than 30 seconds and the terminal display is stuck at 'Running rageagainstthecage....' remove the USB plug momentarily and plug back in.
f) You should get the message “***IF IT KEEPS LOOPING, TRY DISABLING USB DEBUGGING NOW***” followed by an ADB reset, waiting for device, and finally a successful rooting message. (Apparently the looping issue is a known bug).
g) Once this process is complete your prompted to test the root condition. Follow the steps to verify.

Yes, I rooted it that way. Thank you very much!
How about unroot with Super One Click, does it work too?

Now let's put Gingerbread or Honeycomb on it!!

I'm working on an AOSP port of Gingerbread for the Viewpad 7 as we speak. Once I can get the basics working I'll open a dedicated thread.

Really??! That's donation worthy man.
Edit:Then the only thing that would be missing is some way to do TV out. Any ideas?

I don't know of any way TV out would be possible since there is no mini-HDMI port on the device. One of the main things that should be fixed is HD video playback. It really seems like Viewsonic rushed they're tablets to the market. Aside from that and lack of Flash I think it's a great tablet...especially for a developer. Having the 3G radio and GPS is really nice, as well as the screen compatibility mode.

The Viewpad 7 doesn't have flash! What?

It uses a Qualcomm MSM7227 ARM11v6 processor with Adreno 200 graphics, clocked at 600MHz. It's been benchmarked in direct comparison to it's 1GHz Snapdragon cousins, so don't let the clock speed fool you (performance would be comparable to the original Motorola Droid). It's certainly capable of running Flash, but Adobe has been less than forthcoming about releasing a version which will support this architecture.
There are many other devices using this chip that have been released just a couple months ago, so it is still very much in wide use. I don't think anyone has ever found a workaround (aside from using Flash Lite). So until Adobe comes around, we'll be stuck using Skyfire.

I just got my Vpad7 yesterday, and i'm already annoyed at the default 2.2. Even as rooted, my milestone with 2.3.3. still outshines it.
I cant even find an update.zip it'll accept. So when you got something worth testing, or a kernel worth booting, please allow me to test it

superone click superb!

I'm stuck at the moment on the boot.img, but once that's done the rest should get a little easier. I've attached the original launcher apk and dex for Doc. Hope you can get your tablet fixed up again.

Because Adobe decided not to support the ARM11v6 processor architecture, even though they had a working build for it. You can use Skyfire browser to watch flash videos in the meantime.

BTW, guys, where to get and how to install custom recovery on Viewpad7 ?
I can't install custom ROM, reason of stock recovery wan't install unsigned update.zip ;(

Hallo guys..
I tried on my viewpad7, superoneclick 1.7 on linux ubuntu.. but no success.. any hint for me?
always stop at
chmod..
I read to do a adb reset, but I am a bit ..
For the recovery rom I saw in modaco that there is a clockwork recovery rom ad hoc.. but I need root to install it.
ahh, before root it, I wish to have a backup, anybody know a way to backed up the original rom ?
thank you!!!

Per request I've created a separate thread documenting the installation of alternative recovery partitions and installing custom firmwares. You can find it here:
http://forum.xda-developers.com/showthread.php?t=1015005

Hello,
no it sounds that in linux the SuperOneclick doesn't work with this viewpad7..
I read some groups in germany and only windows 7 ... umm
But really there is no way to backup the rom before root?
I am in with adb .. but read not permitted..

[Urgent] Rooting Optimus V (not-active)

I have an urgent question regarding rooting my new Optimus V (Virg Mob), that if possible, i could use an immediate answer for i have very limited time.
I recently purchased a like new, used Optimus V 2.2 o/s off a friend, that is currently not-activated on the Virgin Mobile network, but have been sending/recieving calls and texts through Wi-Fi apps such as Line2 and netTalk. Is it possible to use sublimewulf's method of rooting the opt_v without service (prefer one click root)? i understand that it says it must be activated, but im curious if Wifi will work just as good, or if there is a simple ''one click root'' method i could use. im just not sure why it must be active, im not sure what is done during the one-click method.
Can I root my Optimus V with a One Click root program/app WITHOUT service/activation? If so, could someone please point me in the direction of the download + instructions? Much thanks, its greatly appreciated for all future help- you have no idea..
Thanks XDA Dev team + members,,

Just click the thank button ;-)
Thank you very much, is it normal for the file to be especially large? not sure if the optimus could fit a 173mb file.
Also, what are the chances of this bricking my opt.v or ultimately destoying the operation of the phone??
Also, could you recommend a few ROM's? I heard cyanogenmod is rather popular, but what is it? whats it do- what makes it so special, i guess is what im trying to say. also, is it possible to put the new gingerbread o/s on my opt? would it run as smooth as it runs as is? thanks again, so
what would be a nice ROM to install, and where can they be found (free). also, what are the chances of this root device destroying my handheld, or bricking it? thanks again bro for the fast and accurate response! +thanks for sure!
Oh also,

What is the meaning of this, under the fastbootroot thread? if this program at least works, why would he tag it as being deprecated? also saying he is tired of the complaints. please exp?
thank you. im trying to avoid the slightest bit of damage done to my new phone.
***EDIT::: Do i download the files (from the link you posted) to my phone, or my pc??
He means the complaints of him not working on it.
All you have to do is download this on your computer, as well as the LG drivers, and choose the [Full Package] option, and it will root your phone. Afterwards, see if you can get into recovery, and if not, run the program again and choose the [Flash a custom recovery] option.
Ive used this several times, never a problem.
Best ROM for me was Harmonia, which can be found on Android Central.
i tried both quickbootroot (your link/app posted above) , and also SuperOneClick v2.2, and neither one worked. I tried SuperOneClick, opened the program, and clicked [Root], (after connecting USB to droid, and turning on debugging), and it froze at Stage 2. How do i fix this, and what could cause it?
Im not sure if the cable im using is a charging cable ,or a data cable. i didnt think it would matter, but anyway, how can i tell, and would this cause it?
When i tried the quickbootroot, i opened the .bat file, the disclaimer came up, i hit [y] and enter, and it just went away- nothing happened...
I also ran the usb drivers exe on the computer (i hope this was right), and nothing happened from it neither.
What did i do wrong, and how do i fix this problem? I just want to root my device already...

[DEV & CWM Recovery for Pantech Crossover]

Forgive me if I'm posting in the wrong section. Forgive me if I'm not allowed to post here yet. Just forgive me in general. I don't want to be banned or anything like that. I'm Extremely interested in android development.
I made a working port of ClockworkMod Recovery v5.0.2.8 for the Pantech Crossover. I wanted to do this before I started tinkering around with porting cm7.2. So that I would have a way to backup, restore, and flash new roms, etc... Or else when I make a noob mistake like yesterday and have a non booting phone resulting in having to flash my old boot.img with fastboot...anyways..
DANGER: DRAGONS AHEAD
FLASH AT YOUR OWN RISK
YOU HAVE BEEN WARNED
The method I used to flash the recovery was:
1)adb push recovery.img /sdcard/recovery.img
2)flash_image recovery /sdcard/recovery.img
3)repeat step 2 (for some reason it gave me a read error out of memory the first time)
Here's the link to the custom recovery:
http :// dl. dropbox .com /u/20070520/ recovery.img
I know I'm not supposed to post links yet. Remove spaces
I just hope that there are others with the Pantech Crossover that are interested in this and the possible future development of custom roms.
Also if anyone knows if there is a good way to get ahold of koush let me know, so I can give him what he needs to hopefully add this to Rom Manager. I couldn't message him on github because he doesn't have an email set up with it
And while I'm at it. Here's the method for rooting your crossover. I'm not going to provide the files since they can easily be found with a google search.
1: Find a copy of gingerbreak.apk and copy it to your sd card
2: Enable usb debugging and allow installation of non market apps
3: Install gingerbreak
4: Root device with Gingerbreak
5: You can uninstall Gingerbreak when its completed.

Thanks so much for this! I have a friend with a crossover and is always looking for my help with making it work better. I realize this is a newer thread, I was wondering how things were coming along with CM? Anything I can do to help perhaps?
crap i need a rom to fix my crossover the buttons are no longer mapped after a hard reset. please help.
Slow
Well, it's been slow goings so far. I downloaded the open source files for the p8000 and it looks like they just built the original rom from a generic build. I've been trying to get a more customized build setup but I need to do some more reading so far. One of the problems is that instead of an akmd(2) binary for orientation and compass it uses three separate modules. Plus the hci_attach is a bit different as well and so is the bluetooth. So that significantly hampers the ease of even a basic port.
As far as the gentleman with the question about a rom to fix your device. The best I can do right now is to upload a clockwork mod backup after I do a factory reset. I don't get much time to work on this between my wife and daughter.
Also, do you have adb access to your device? Surely it wouldn't be too difficult to adb push the correct keymapping files back to your phone.
You say a hard reset messed up your mappings? What problems were you experiencing prior to the reset?
Crossover
Hello,
I just wanted to let you know that there are people watching your thread. I am very interested in this as my parents have Crossovers and have recently rooted and unlocked them (well, I did) and set them up to work on Net10.
The only issue I've noted is that there are some failures, like the Market refusing to install apps no matter what is done. I'm going to install your ClockworkMod in hopes that later it might be useful.
I realize there isn't a large development scene for the P8k yet, and maybe there won't be but it's always a great hope that those with the capabilities might take pity. I was almost thinking that it might be my foray into actually looking deeper at the code than the small bit I've done.
Kind Regards,
Kaylus
Yup

I haven't had any problems with the market refusing to install apps but I do sometimes run across the no connection error with the market when on wifi. Although I did notice this before I rooted my crossover. Sometimes disabling and re-enabling the wifi helps. I really do think it is a bug somewhere in the original rom.
As far as the custom recovery image. Everything seems to be working pretty good. I use it mainly for restoring previous backups. I would say I've restored my backup at least a dozen times. Occasionally it states there was an error restoring .android secure but I have yet to track that down. I need to double check the recovery.fstab to make sure I have everything set right for the mount points.

I'm actually completely stuck at this point. I'm rooted, unlocked, different carrier, APN set correctly. I can access data and voice -- but it just hangs at "Downloading..." on the market. If I factory reset it works initially but after reboot it fails. I'm not quite sure why this occurs and if it is just this phone or a side-effect of using it on a different carrier.
Strangely Wi-fi doesn't resolve it.

I'll give your recovery a run and let you know, if you manage CM7 let me know I know it's a big undertaking. Thanks for the response.
Market Error
As far as the Android Market hanging. I see a few references to it being cause by the .android_secure folder becoming corrupted on the sd card.
One temporary fix suggest moving all the installed apk's back to the phone memory and deleting the .android_secure folder. Then rebooting and moving those apps back to the sd card.
That seems like some wasted time if it doesn't happen to work. I would just turn the phone off, remove the sdcard, and restart (granted any apps that were moved to the sdcard wont work until it is reinserted.) Then I would try to download and install an app. If that works then shutdown, insert sd, and reboot.
I'm really curious if the problems with .android_secure that you and i are having aren't just more bugs in the original rom.
Just as a poster above me said, I am watching this thread and really appreciate everything you are doing. Thanks again.
Well I appreciate the support. I just hope to be able to offer a rom sometime soon. Unfortunately I won't have anymore free time till Tuesday

Pantech Crossover Update
Ahhhhh check out the pantech support page for the crossover. They finally have the Gingerbread update.
http:// pantechusa. com/xupgrade/ remove spaces.
Which is great because I soft bricked my phone (don't ask) and this was going to be the only way to fix it.

Mildly related, but have you figured out how to root the gingerbread ROM? I've tried ginger break to no avail.

anyone have a stock image of the 2.2 for android my phone came preupgraded to 2.3.6 and i would like to have it rooted over being on gingerbread since a root method hasnt been found yet for the new firmware
Bricked?
I tried to use the pantech provided gingerbread update this morning. It got about an eighth of the way through and failed. It instructed me to reboot while holding volume up and home and power. That put it in software updating mode. I tried the upgrade 3 more times, it failed at the same point each time. Now my phone is stuck in S/W Updating mode and I can't seem to get it out. I've tried pressing volume up and down for 10 seconds, and pressing volume down and home while powering on, nothing seems to make a difference. Any thoughts about how to at least get me back to froyo?

Lenovo IdeaTab A2107A-F

I am starting this thread to hopefully encourage discussion on the Lenovo A2107A-F tablet variant.
I am aware there is an existing thread on the A2107 here:
http://forum.xda-developers.com/showthread.php?t=1982334
but that thread is concentrating on the A-H (dual sim + wifi) variant which is somewhat different from the A-F (wifi only).
So far I have not found any custom rom development, which is disappointing as the stock rom leaves a lot to be desired IMHO. While the current OTA update is fine for web surfing, reading emails etc, HD video playback (particularly YouTube HD) is very poor. Also the recent OTA update forces an optimization of apps on bootup which leads to long boot times
You can root and install CWM by following steps 1-5 from the 1st post here:
http://forum.xda-developers.com/showthread.php?t=2044496
Note that "-Update 3-" mentioned in the post does not appear to work for the A-F model!
So, has anybody any leads on possible development on this tab?
Any tips on improving performance?
My first tip:
If after installing CWM you cannot get to the CWM recovery screen after powering down the device, look for for the file "/system/reboot-from-recovery.p". If it's there, either delete it or move it to some other place. This file restores the default recovery on a system reboot.
I got bitten by this a couple of times
Thanks for starting a separate thread for the A2107A-F. I'm new to Android devices and just got this one two weeks ago. I'd like to get rid of several of the apps that I have no use for and from what I understand that means I have to root it. I got lost in the details of the other thread, but I tried reading all of it. I'm on Vista and somewhere along the line I installed one of the suggested ADB drivers via PDAnet. Device Manager is showing Android Phone and under that Android ADB Interface. I wasn't sure if that matched closely enough with the step-by-step threads since I don't really think of the device as a phone, so I've been holding off on going further. I've tried using a few other drivers that were suggested in the large thread and some other threads, but Vista always tells me the current driver is the most up-to-date one.
Do you know if it's okay for it to say Android Phone rather than something else?
Thanks. I've got some other questions about the specifics of some of the other steps, but this is probably enough to get started.
My apologies in advance if my posts are too long and my questions are too basic for these forums. Feel free to point me somewhere else based on what I'm asking for. I'd honestly appreciate any leads towards my goal of getting rid of the bloat on this device and making it more responsive. (Wow! The portrait to landscape lag is really bugging me now after reading around here).
Anyway, my primary purpose is to remove the seemingly unneeded programs, services and widgets that come with the tablet. Maybe I'm just ignorant about these things, but at this time things like messaging (IMO), mapping, and some of the other default features are of no use to me. They seem to be eating up a lot of resources. I can kill some of the services I think they are associated with, but they keep popping back up.
I did watch the "noob" video (color me a tiny ant to be squashed) and did try to search for an answer to get me even started. I've read the huge main A2107A thread (80+ pages) and tried three of the suggested ADB drivers with my Vista 32 setup for my A2107A-F. The only one that even seemed to connect was ADPnet and it showed the tablet as a Android Phone. Maybe I'm just too paranoid, but after the multiple "brick" posts I'd like to make sure I'm on the right path before trying to "root" the device which appears to be the first step in removing all the extra stuff Lenovo added.
Not that it matters, but I've had the tablet for almost two weeks now and my favorite things are Slacker Radio, Scrabble, Roll It and Zen pinball. I do play Words with Friends with my wife, but I don't like it since some of the words they allow are not valid in Scrabble (which I used to play as an expert competitively face-to-face).
If you are so inclined, feel free to PM me for a Scrabble game. I promise I will not use anything other than my brain and the built in dictionary to make my plays. (I'm a bit rusty since I gave up competitive Scrabble in 2006).
So, long story short... Thanks in advance for any and all advice you can give on slimming down the Lenovo A2107A-F. And if you want an honest Scrabble challenge feel free to PM me.
As far as checking if your drivers are installed properly I would open a dos (command) prompt in window and from within the window change to the directory where you have the 4.03root files. From the command prompt type 'abd.exe shell' and you should see something like "[email protected]:/ $". If you don't see this then you will not be able to root! You need to make that USB debugging is turned on on your device you have an entry in the device manager for ADB Interface (expand on the device which you have showing up).
I am no expert, and I struggled with this on my first go also
Once rooted you can then install Titanium Backup from the play store and use it to get rid of the bloatware! Proceed with caution however as it is possible to remove critical system apps!

Thanks! That's the type of test suggestion I was looking for to make sure I was on the right path with the driver.
So has anyone tried creating a rom for this tab yet? I've been doing some research into porting another rom to work on the A2107A-F, but want to make sure there isn't one already.
I just received a notification of a new firmware update for the A2107A-F. This would be the second available update.
Has anyone else gotten this and taken the plunge yet? I'm curious if this is possibly Jellybean, as some of the larger screen IdeaTab models run this.

I lost root after applying the first update a while back. That's typical when updating. Afterward, I was able to re-root mine again using the same procedure as before. All was well. So, don't panic...yet.
Can you report on what other changes the update made? Is it Jellybean? Or maybe ICS 4.04?

Although I have my A2107A rooted and tweaked to my satisfaction, there are a few lingering issues that I'd hoped an update would correct:
1) The neutered Bluetooth stack. The tablet is supposed to work with Bluetooth keyboards, mice, etc. It doesn't. Although I've gotten it to talk to an external GPS module, other Bluetooth data connections simply will not work. Oh, and Bluetooth audio? Forget about it!
2) Some settings that are present in stock ICS builds are just omitted in this one. As an example, the ability to specify a default TTS voice. It's present under settings in my wife's tablet and every other ICS build I've ever encountered. Not this one!

I was rooted too, lost root access (only with some apps!) after the 130221 update Feb 28. I'll try the same root procedure as before to see if I can get it back. Glad to see a thread on the popular US version A2107A-F. Maybe someone will port Jelly Bean to this tablet! Doesn't appear Lenovo wants to do it...

I cannot get this 'update' to install after downloading. The tablet reboots to CWM during the install (I am rooted with CWM installed) and when I attempt to manually select the update.zip from /sdcard/googleota/ I get on error (status 7). In desperation I re-loaded the stock rom that I found on another thread and when the tablet attempts to update I get a "assert failed apply_patch_check( /system/app/applicationsprovider.apk)" error Anybody any ideas?

I'm in exactly the same boat as you. I'm getting the same exact error. except that I do not have CWM installed (I am rooted though). Perhaps there's a problem with the update.zip?
Something odd that I noticed however: After the tablet reboots into recovery mode, the update fails, and I go to browse for the update.zip, the sdcard/googleota directory is missing (along with everything that follows it alphabetically). They reappear upon normal boot. I've tried copying it to a directory closer to the beginning of the alphabet and it does show up while in recovery mode. But it still will not install.
Maybe I somehow do not have the available space to perform the update? Is that possible? I show plenty of available space on both sdcards. Could we somehow be below a certain ROM space threshold necessary for an update?
I think in my case because I loaded a 'stock' rom I got from another thread, this rom is failing a verification test the update is doing before install. I do not know how to get around this! I'm continuing my search, but I am not so confident this will be resolved easily...

Well, I am running a stock rom. I am unwilling to "mess with success" until there's a 100% reproducible way of recovering if it fails. And, so far, everything I've read in the other A2107A thread has been hit or miss for the A2107A-F people.
Anyway, If the update is performing a verification test, then it my "virgin stock ROM" should certainly pass it. The only thing that I did is to root it. Hmmm...could the update be testing for that and refusing to install if it detects a rooted device? I would tend to doubt that, since the previous ota update went just fine. I lost root in the process but easily reapplied it afterward.
Thoughts?
Interestingly, I flashed the A2107A-F_S483_121115 rom (again, found in another thread) as I was having verification problems with the OTA update just released from lenovo which was available from the A2107A-F_S484_121211 flashed rom. While the S483_121115 rom appears to be older, I no longer get the option to update via OTA as the tablet is telling me that my s/w is up to date! Go figure.
It's really too bad this device hasn't taken off. If I actually knew how to dev then I would start developng ROMs for it. I'm enjoying it now that I have root and got rid of bloat.
Hey guys. Just wanted to say if someone can send me a stock rom and be willing to test, I'll try to do up a good rom for the -f models. I'd use mine for the stock rom, but I've edited a lot of the system, so no go there. If you have the stock rom or want to be a tester, let me know.

This thread is a continuation of some of the discussion that was from this thread: http://forum.xda-developers.com/showthread.php?t=2568427
While not at all high end tablets, it's always fun to see what can be squeezed out of them! As stated in the title, this thread will be regarding the following devices: Nobis NB07, Iview 774TPC, and DA-741QHD (which all appear to be the same hardware) rooting and ROMs. That should be pretty simple for now since, we currently have no ROMs and no proven root method. Some have reported success using the Kingoapp. If anyone is able to obtain root, we would like to ask that you make a copy of the firmware and upload it for those of us having trouble doing so. After doing so, we can modify it and hopefully get more our of the software.
You may also post information regarding tweaking the ROMs for these devices and other ways to make them more useful!
Warning: The following may have unforseen effects including breaking your tablet to the point of being unrepairable.
Option #1, Use KingoApp Some users have reported that this did not work for them, at least one user reported that it did.
Instructions per RawX:
For the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers. That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times. I've done this were for clients of mine but its pretty straight forward.

The working drivers for me were: VID_1f3a_PID_efe8
Please consider trying this first and give us some feedback. A word of warning though, there has been some discussion on XDA in the past that this may be malware though I'm not sure this was ever confirmed.
Option #2, Flash firmware for an alternate device that can be rooted easily. Warning!!! Currently, there is no way to get back to stock (until someone who gets root with another method makes a copy of the firmware)
Go to this website: http://www.iviewus.com/firmware788TPC/ and download the firmware. Yes, it is for another tablet. However, the tablet appears to have the same specs as ours. Once downloaded. Install the included PhoenixSuit software. Once it is running, click the button at the bottom right to update the software to the newest version (this may not be required). Then, plug in your tablet using the usb port and install the drivers. I used google and found them all within minutes. Once the software recognizes your tablet go to the firmware tab where you have extracted the .img file and select the file. Next, click upgrade to upgrade your tablet (it has instructions to help your tablet be recognized if you are having difficulty). Once the new firmware has been flashed, then download the file RootFromOTA.zip that can be found on various places such as XDA. Move the file onto an external SD card. Then, go to settings -> backup & reset -> Recovery Mode. Your tablet will restart. Once it does, select the bottom option to install from SD card. Install the RootFromOTA.zip and then reboot. Once rebooted, install the supersu app or another root application of your choice.

Congrats... You're rooted.
Mods
Currently, I've managed to get great battery life out of my tablet by installing kernel tuner and changing the settings as such:
Governor: Ondemand (default is fantasys)
Max: 1200 MHz (Default is 1200 MHz)
Min: 240 MHz (Default is 120 MHz, but I had trouble with usability at this setting and Ondemand)
I also recommend setting wifi to turn off when the screen is off and turn off autosync.
This seemed to give me a very useable system but with greatly improved battery life. Doing the above and a few other tweaks here and there have made my battery life so that it drains by about 1% overnight when not in use. I also seem to get better battery life while using the tablet. I haven't had any trouble playing games either.

I am assuming the camera is not working using this method or did you figure it out?
And also, do you have a link to the drivers you used off hand or what did you search for to find them?

Nope, still haven't gotten the camera working. We are missing some config files still. Do you need the camera drivers or the tablet drivers?
The camera drivers are : sp2518 and sp0838, though I also see a module being loaded called cam_detect
I don't recall where I got the adb usb drivers for the tablet, but it would probably be a good thing to mention in this thread so if you have them, let me know and I can add it to one of the top posts. If you're having trouble finding them, I'll remove my drivers and go back through the process to find them again.
Looking for the tablet drivers. I am about ready to tap out on this thing for a while. lol Its driving me crazy.

OK. The drivers I used were probably: VID_1f3a_PID_efe8 (or something similar)
You can either google that or try downloading the firmware for TP718AQ here: http://www.agptek.com/forum/viewtopic.php?f=22&t=948
Remove all prior drivers for the tablet. Plug it in and tell Windows to use the drivers from the extracted file you download (Will extract to TP718AQ_Update_Firmware\USB Driver).
Sometimes I have to do a little dance with restarting the device and my computer to get it to recognize it.
As a last resort you could try this: http://www.xda-developers.com/andro...r-solves-your-adb-driver-problems-on-windows/
Let me know if you have any problems.
Good Luck!
Ok, I officially give up trying to root this thing. Stupid windows will not install the drivers in both the links you provided and I cant get windows to even try to install anything after removing them then I got the android ADB drivers to install but still zero luck. All rooting apps fail. Hopefully someone will post the image of their rooted NB07. A few claim to have rooted it just fine but I cant win with this thing.
All I want is to be able to run link2sd and a few other apps that require root. This is officially the longest I have owned an un-rooted android device. lol
I'm the one that got the root working using kingo, so for the drivers the easiest method is just using Top Notch Tablets How to install ADB drivers ( I would post a link but I don't have 10 posts yet on XDA)
That worked on the first one, the second one it didn't not entirely sure why, but you can send a email to support and ask them for development drivers for the nobis tablets and they will send the ADB drivers you need. After you have the drivers installed use kingo while the tablet is in usb debug mode BEFORE plugging it into your usb port and do not turn on usb transfer. the first time after it reboots kingo will report that it was not rooted, leave it plugged in and power off and back on and it should report the root worked. This method gives you SuperSU. Both times I've done this were for clients of mine but its pretty straight forward.
Well, I have decided that for now this tablet of mine is un-rootable. I must have tried with 5 or 6 different drivers about 20 times with each with Kingo. I even tried that other program that is all in Chinese that loads some BS app on to your phone with no luck. So, for now, I am going to give up but if anyone has any other ideas or wants me to try something or they have for sure figured out how to root it, let me know as I am happy to help the best I can.
Edit: Oh yeah, Dont know how much this will help anyone but here is some more specific specs on the Nobis NB07 tablet I pulled off it with Hardware Info 3.0.0. Feel free to put the link in the first or second post if you want. Maybe it will help a little bit more.

Thanks to the work of someone on another forum, I have now got TWRP working on our device and am hoping we will soon have a CM working on it as well. Check back in the near future for further details. Maybe if you can't have a rooted stock, we can get a fully functional CM.
I am assuming you need to have root to flash the TWRP recovery correct. This is good news. Would love to have more info on it. Are you working with people on this site or another site? I would love to follow along.

On another site for now. Just PM's at the moment so not much to follow yet. But, all you'll need is the Phoenixsuit to install it, so you won't have to root your tab first. You'll have root on the new ROM. You'll have to have drivers fully working though. Once fully working I'll link to the site so people can get the files and hopefully we can get this guy some donations for his work.
Awesome! I would go right to CM on this and skip the whole rooting the stock firmware. Would be nice to be able to root the stock firmware though then things would be so much easier. Think the camera will be working on the CM build? If not no big deal but would be nice to have them working.
Keep me (us) posted on the progress.

Not sure about the camera yet. I have CM booting but no touch yet, so this will be the first task. I'll keep everyone posted.
Any word on getting things to work yet?
Currently, we have CM working with no touch screen/camera. I'm not sure what else all isn't working because I'm waiting on my OTG cable to come in for further testing to see what all is going to be required to get the touchscreen going. Right now, it appears we my be looking at compiling our own drivers which could take some time to do. I think we'll get it eventually, but it may take some time. If you don't need touchscreen or camera, it could be working right now.
Sorry for no updates for a while. My work has been delayed on this since I have a son who is sick and in the pediatric ICU. I'll get back to work when things calm down for me.
No worries man. Family first.
Just a question, Hippie...
On the original ROM, can you see your device in ADB? If you can, and type "adb shell" do you get root? If you have adb access but not root, can you try typing sh and see what happens?
Also, could you try loading the rootfromOTA.zip and see if you can get a printout of the error log if possible?
Also, I tried installing this from the recovery on a similar ROM and it acted like it failed. I went back into the ROM and used adb and was able to get root using vroot or kingo...I don't remember which. This may be worth a shot.
Interestingly, I have been looking for alternative ways to root and found this (but we need to find a way to get to the bootloader):http://whiteboard.ping.se/Android/Rooting
I think that the method to get to bootloader is to turn off the tablet, then hold down the back button while tapping the power button 5 times. But, I also googled and found a method for getting to fastboot from adb in android without root as well which may work.

Added to the oP!
I also suggest to add a link to an international ROM of REMIX OS that also includes English as system language and the Play Store is preinstalled .
This is the link:
http://www.mediafire.com/download/k8ci6r38hmza431/i7-cx_remix-2015052202_with_Google_Play_Store.rar
The password is: geekbuying.com
Inside the archive there is also a tutorial and the flash tool
I hope this will help... I used this rom for my video review
I think that is also possibile to install Win 8.1 or 10 in this tablet... someone has already tested it?

Found it and now have root on B2015092001. In regard to the GPS it appears it isn't working as when I run a GPS test utility it can't see any satellites however as long as you have it connected to a wifi network the tablet seems to have no problems finding your location for Google Maps or a weather app. While full GPS support would be nice to be honest I don't think I'd use it much in a tablet this size and I don't really miss it.
B201509001 with Play Store Results
I installed the newly available B201509001 from:
techtablets.com/2015/09/new-cube-i7-remix-intl-rom-supports-ota/
because someone mentioned better battery life, my most profound complaint about this tablet.
I can testify that battery life is considerably better, but perhaps at the expense of some functionality. I notice a few appearance changes scattered around the OS, but most are harmless. The big issue is the lack of GPS. I can turn it on in the settings, but no data is received from it by any application.
I don't know when to expect an update from Jide, but the Dell Venue 10 5050 uses the same Atom chipset and runs Android 5.0. I am not sure what exactly is preventing an update.
Updates from 4PDA:
1) We now have a working TWRP recovery thanks to users jemmini and Allegator. Version 2.8.7.0 to be exact. They do mention however that the swipe to unlock function is a bit tricky so it's best to disable it in the settings.
Link: http://4pda.ru/forum/index.php?s=&showtopic=682005&view=findpost&p=44312325
When you unpack the downloaded RAR file it has script to install (recovery.bat) however I found that didn't work for me. so here's the way to do it manually:
Ensure you have enabled "USB Debugging" under the hidden "Developer Options" menu
Plug the tablet into your computer via the top micro-usb port (the one you charge it on).
Find the folder that you unpacked the downloaded RAR file too
While holding down the left SHIFT key right-click on the folder and select "Open command window here"
In the command prompt that comes up type "adb reboot bootloader"
Wait for the tablet to reboot into bootloader mode
Once the bootloader menu is on the tablet's screen type "fastboot flash recovery recovery.img"
Once it's finished flashing use the on-screen bootload menu to reboot into recovery and disable the screen time-out under setting
Go back to the main TWRP menu and reboot to system
2) There's a clean and stock android ROM due to be released tomorrow! Not sure if it will be KitKat or Lollipop but word is it will have working GPS.

LAUNCHER
Hi folks,
does anyone know how to change default launcher in OS Remix? I´m using the latest official rom (I7 Remix-B2015092001-signed) and I would like to use mine purchased Nova launcher but the tablet says something about no support for apps from third party.
Thanks for advice
