The tablet that I am dealing with is a "Cruz Velocity Mini Tablet" running android 2.0 and no means of installing apk's.
Currently this is the situation:
A friend of mine lent me her Chinese reader tablet.
I told her that I could probably flash a newer version of Android on it, thinking that I could finally try my hand at making a ROM because I know for a fact that there aren't many ROMs if any at all out there for a chinese off brand reader like this.
After rooting the tablet I deleted the pre installed bloatware via ADB commands (shell) including a file manager (Astro) that I believe was the only way that you could browse files on the tablet, as well as some other pre installed applications that must have been necessary in retrospect. There is no existing vending capability or market application.
I am looking to make a custom ROM (Using android Kitchen and Cywign) through following this tutorial by lokeshsaini94 yet I feel like following that tutorial won't even get me where I need to be.

Things that I have tried at this point include:
Attempting to connect the tablet to my computer with the SD inserted (with and without debugging turned on) [Failed to show up on my computer as a device or anything]
Downloading the APK that I need from a file sharing website [Downloads fail]
Uploading the APK that I need to my Google drive and downloading it from the tablet [Says waiting for data connection and doesn't download even though connected to our WiFi]
Inserting the SD card into my computer, copying the APK I need over to it, then inserting the SD card back into the tablet, going into the browser and typing "File:///sdcard/<name here>.apk" to install an APK but getting an error in the installer after pushing 'install' -> 'Application not installed'
Trying to perform a factory reset; this simply makes the tablet reboot with everything the same as it was before.
Essentially guys and gals, my tablet here is running Android 2.0, I want to update it by making my own rom for it to something at least >4.0, and it seems that I've made things worse and have no way out of this mess. I think I've essentially bricked it even though it still works. :silly:
What do I need to do to make a custom ROM let alone flash/wipe this tablet?
All help will be incredibly valuable
There should be plenty of info here http://www.slatedroid.com/forum/93-velocity-micro-cruz-reader/ to get you on the right track. Not likely you'd be able to get anything beyond Gingerbread on there running due to lack of source code. Your only hope would be to see if there is a newer tablet with the same chipset that has something newer on it to port over.
Still no paddles

Thank you very much for your response. It looks like on that website I've already found multiple useful roms!
In fact I already downloaded one and put it onto the SD card. Apparently for these tablets you're supposed to, while powered off, turn it back on by holding the power button and the volume up button but all this seems to do as a whole load of nothing.
I fear that what I've done to it by deleting potentially sensitive programs previously, I have somehow managed to make this process impossible.
Is there some kind of way that I can plug this tablet into my computer and be able to completely wipe it so I can, at the very least, have a functional tablet that will work at all? I've done approximately 5 factory data resets yet the background image that my friend has on the tablet as well as seemingly every single setting and application is remaining untouched..
Try the ones here that also install a custom recovery: http://www.slatedroid.com/topic/33586-a-clockworkmod-rom-compendium-for-the-cruz-reader/
You'll want to make sure and rename the file exactly as mentioned there on the OP. Install instructions are included too. I don't think there is a way to reload via the PC. The right zip should get everything working properly.
I am trying to sideload cyanogen mod. Whenever I boot the phone into TWRP, Windows 7 (64 bit) tries to install MTB USB Device drivers and fails.
Driver Software Installation:
Device driver software was not successfully installed
Please consult with your device manufacturer for
assitance getting this device installed.
MTB USB Device X Failed
I already uninstalled Android SDK Tools and re-installed, making sure that Google USB Drivers are installed. I also installed Motorola drivers, but that was at the start of my journey and I didn't take notes on the details.
I have no problems accessing the phone via USB when the phone is booted up normally. I also have no problems using fastboot when the phone is is bootloader mode.
I originally tried a number of ways to use CWM instead of TWRP, but was unsuccessful. I've posted those efforts in this forum and abandoned CWM after a while.
Has anyone who owns a Moto G actually been able to install CWM or install CyanogenMod using TWRP? I want to use adb rather than non-mainstream tools, and I'm not interested in rooting at the moment (though rooters are more likely to be familiar with issues at this level).
From further web search, this is the last news that I can find about MTP USB drivers when booted up in TWRP: <<erroneous URL removed (I can't re-find the correct webpage)>>
I'll continue sleuthing a bit more before looking at how to install cyanogenMode without sideload. But for now, it seems that the MTP issue remains (though I admit, I'm new to the whole smartphone thing and I could be wrong about that).
Afternote: I chose sideload so that I wouldn't have to worry about where the cyanogenMod zip file goes. From using adb shell to "ls" around, it seemed a bit confusing, and it wasn't obvious how the directory structure from "ls"ing around matched the 5-7 partitions that are on most Android file systems. In fact, entire subtrees seemed to repeat themselves at different parts of the tree.
I followed a suggestion on another forum and used the push method. I followed wiki.cyanogenmod.org/w/Install_CM_for_falcon. I found that I needed to bookend sdcard with slashes: "/sdcard/".
I am now facing the (apparently commonplace) problem of being in an endless loop with the popup "Unfortunately, the process com.android.systemui has stopped. [OK]". I'm one step further, though. There seem to be many causes for this problem, with varying degrees of similarity in the symptom. I've not yet run across a case with exactly the same symptom, where the loop occurs at the language selection screen. Of the various circumstances that I've read about, the one that seems that it might be most relevant is the association of this error with an Italian keyboard app. In my case, the English (Canada) language seems to be selected, if I'm interpretting the graphics properly. I will try replacing the keyboard apk with one from a nightly. New territory.
The other causes are flipboard app, ART vs. Dalvik, and possibly a few others.
Someone suggested that I might try clearing data and cache on Google Play Framework. I googled how-to-clear-data-and-cache-on-Google-Play-Framework, and read www.androidpit.com/google-play-not-working. It seems that you have to be able to get the OS working before you can actually clear those Google Play data. I haven't been able to get beyond the language screen. I can't access the device via adb, either.
Afternote: I was able to press Next a few times in between the error message popups, and I got the the home screen. The devices shows as XT1032 in the Windows Explorer, but there's nothing in that "folder".
Update: I don't have any app beginning with the word "Google", so it seems that none of the above measures having to do with Google Play apply in my case. I suspect that this may be because I'm working with a virgin install of CyanogenMod. Looks like I'm still on search for a way ahead. I also tried switching the language from English (Canada) to English (US), based on the info I found online that the problem was due to a keyboard apk. No joy.....
Update: Another user had the same problem and solved it by reverting to CM 10 (www.reddit.com/r/cyanogenmod/comments/2gvmqu/cm11moto_g_comandroidsystemui_is_crashing_after). Looks like I have a way ahead.
Just saw this on the official Nubia page, appears to be android 5.0 with split partitions for Nubia Z7 mini dual sim:
http://www.nubia.cn/service.php?sid=5
(use translate)
Has anyone tried this? or seen it before?
I am rooted and gapped so I am a few versions behind as I lost OTA abilities, has anyone got this OTA? Would prefer to do it via this method than using their tool.
EDIT:
Looks like tomorrow is the day:
Dear Cowboys: Hello, everyone! Thank you very much for the concern and support of Nubia.

new stable Lollipop for mini's been officially released
link( in Chinese): http://pan.baidu.com/s/1hqGSezy (password:5mpy , MD5: 2651F3539381AA0B12A21B54729E2EBD )
Above rom can only be upgraded via official upgrade software: http://pan.baidu.com/s/1bnc0J1d (password: 2mua)
Be warned if u choose this one u must use the upgrade software I gave in the link, because there's some changes to the software, using old ones will cause boot loop.
Be warned using this method will lose all ur personal data and apps. U can only upgrade using this method if ur current rom is official 1.82 (4.4 Kitkat) or 2.03, 3.01 (5.0 Lollipop), if using other roms, CM or YIOS for example, the upgrade software will refuse to continue >_<. However, using MIUI6 is OK, because it is based on official 1.82.
recovery zip ROM: http://pan.baidu.com/s/1pJxaYM3 (passowrd:el1j, MD5: 4C409536B1124A86E65F1B66E94E0C2C)
This zip file can be flashed using both official and CM based recovery, provided ur current ROM is official 3.01, otherwise boot loop is also expected
As the files are too large, the only way to download them is by install a clound file management program issued by Baidu. Blame Nubia for not using cloud disk with English support
download link of Baidu cloud file manager:http://bcscdn.baidu.com/netdisk/BaiduYunGuanjia_5.2.7.exe
Just an FYI for other users lookign to upgrade.
My update went well. I installed 1.82 via custom reocvery method. This lost all data but thats what i wanted, to start fresh.
the I used the nubia updater tool to flash the 3.12 rom.
Once the rom is loaded, you will find a lot of junk chinese apps so you will want to clear those out and of course no root or google apps.
here is how to achieve this:
Root - download kingroot pak file from google, run it and you will have root. Its a bit bloaty, you can uninstall all the apps it creates except kinguser (this is the equivalent of superSu) - would be interested to now if anyone else has found a root method that works.
Install custom recovery:
https://mega.co.nz/#!fsMXSC6A!2Vpqy2SGIC_WbFAqNgzE6WgArW2vaWha-zwp_o7yvqE
Enable USB debugging
extract nx507j_twrp_2_8_5_0_NEW archive
connect phone via usb
run recovery.bat
(thanks to another xda user for this)
Boot into the recovery, and install:
pa_gapps-modular-mini-5.0.1-20150418-signed.zip
(google for that file, others may work but this is minimal and does what you need)
Once rebooted, open playstore, enter your gmail, then your contacts and calendar will be synced!
install an app like links2sd or root uninstall and start clearing out all of the garbage apps.
That should be enough to get you started. I will attempt to install xposed tomorrow.

So I seem to be stuck. I had used the nubia updater to get to 2.03 and rooted and dropped in TWRP. After that I did a TWRP backup. Next I did the usual steps and flashed CM12. Now I want to update again; but, my backup file of 2.03 is corrupted and won't boot. When I try to use the nubia update tool it doesn't see the phone even though it says the driver is installed correctly. I have also tried the steps that @rx1 posted on 7 May, but that hasn't worked yet. In my device manager settings it has Android Phone with a dropdown that says Android Composite ADB Interface and the driver is installed correctly. However, a little further in the list it says Other Devices and lists Android with the yellow exclamation. Despite what I try it won't find the driver for that one. It's confusing because one says it is correctly installed (as does the Qualcomm Drivers installer) and the other does not. Ohh, and when I look at my computer (sorry not a PC guy, borrowing from a friend) under Devices with Removable Storage, the phone shows as a DVD player. Any ideas or help out here?
Sorry, posted in wrong thread.
I think you wiped system when you installed CM 12 or later . Your phone has already merged partitions and you don't need Nubia Tools anymore.
- Go to TWRP
- Downlod form PC a 3.01 or 3.12 ROM , preferable rooted .
- install it after wipe only " factory reset " .
If your PC can't see the phone ( only as DVD ) ....try to re-install CM 12 from phone .
The only driver that works:
uninstall all existing items form your device manager, disconnect phone
download package: https://mega.co.nz/#!GN9GSQZL!F4ZMFAPPJKR8VBM0wqPWTaBB2Fuv6C1Go0bFl3fD6SM
run it and select option 1 install drivers
reconnect phone
(dont use this tool for anything other than dirvers on z7 mini.
Also agree with poster above you shouldn't be using nubia tool to flash a cm ROM. Use the instructions cm provide.

Thanks for your help. Although, I will say that I used TWRP to flash CM12, not the nubia updater. I do know that much. Maybe I'm misunderstanding, but it seems one of you is saying that I should use the update tool to get to 3.01 or 3.12 and the other seems to say flash it with TWRP; am I misunderstanding something here?
---------- Post added at 10:40 ---------- Previous post was at 10:35 ----------
The package says Z7Max? Is it actually for the mini?
Yes, as I said above only use this tool to install drivers. They are the same. Don't use it for anything else on a mini.

Thanks. That was my only problem. I had been using the wrong drivers. It worked quick and simple, just like it did before.
First of all hello everyone since this is my 1st post
I upgraded to official 3.01 Lollipop and I want to ask if it is possible to install playstore without root since I want to run an app that won't work if the phone is rooted and I can't find it anywhere else other than playstore, otherwise I would be just fine without all the google apps.
Alternatively would it work if I installed a pre rooted ROM and then unroot it, is that possible?
Hope this thread is suitable for these questions and thanx in advance to anyone that can help.
What app is it called? Maybe I can find it on play store then send you the apk install file.
It's called OTE TV GO but from what I've read even if you can find the apk it will not work unless you have downloaded it from your device.
Well I don't know how much luck you will have because it shows as incompatible with my device. (maybe because Im root?)
Anyways the way to do it is, either from chrome or firefrox install this extension on your PC
https://chrome.google.com/webstore/.../cgihflhdpokeobcfimliamffejfnmfii?hl=en&gl=VN
https://addons.mozilla.org/en-US/firefox/addon/apk-downloader/
go into the options and enter your device ID and email etc. then yeah just do as it says, go to the playstore then the extension will allow you to directly download the apk file then copy it and then install to your device.
Second option is, there is a app called "rootcloak" that will hide the fact you are rooted from any apps you choose to, so in theory the playstore and ota thing wont know you have root.
I tried the firefox extension but when I try to download any app I get "Cannot download this app.
Login session has expired or your email and device ID are incorrect/not activated on Google Play app"
Will try second option as soon as possible. Thanx anyway
Hello everybody, I'm just new here. I need your wise help with a Lenovo S820e.
First of all, the story: Got a Lenovo S820e from a chinese guy. Received a smartphone with lots of chinese garbage on the rom including pornography and things like that, so I decided to look for some guides to reinstall an official ROM for this Lenovo. Honestly I'm a beginner with these things and took me a while after realizing how to do all the proccess.
After reading some basics and check some youtube videos, I went to NeedROM website and looked for this ROM:
***can I post a link?***
Realized that this is the only ROM version (some updates here) but finally the only one that I've found on the internet.
I followed the steps (took me some days, lol) to update via sdcard posted on that ROM link (here the steps):
Install ROM:
Need a memory card, create folder sdfuse and copy to install on this ROM (QSB tailed).
a) normal phone boot into Android OS, use a USB cable to connect PC, the pop-up screen, select USB mass storage devices, and turn on USB storage device;
b) New sdfuse folder, unzip the downloaded firmware, and copied file QSB to the phone sdfuse directory;
Note: Make sure before upgrading phone there is a certain amount of power
2. T card upgrade process
Long press VOLUP + POWER_KEY enter droidboot, a menu appears and select the fourth SDUPDATE, the bottom of the screen you can see the progress and status upgrade
See "SDCARD UPDATE SUCCESS!!!" Indicates a successful upgrade
After some tries, realized how to enter that droidboot (Volume down + power button... after seeing the lenovo logo release the power button). :good:
To shorten this story I finally got a "Lenovo S820e android 4.1.2" with an official ROM, rooted (to get rid of these chinese apps, no offense intended) and without google apps. Here is the part where I spent another few days to install gapps because didn't accomplish with adb loader, cwm recovery, etc.
So I found this guide (russian site, translated with google help) on how to install google apps without CWM, a something like a manual installing:
****????****
Installed the root explorer and copy-pasted the system files to the internal storage, permissions and rebooted the device.
But after boot I got a look-a-like, useless "Assistive touch-thing-app" ( I don't know exactly what is ) that I cannot find how to uninstall it. Note that this was after (at last) installing gapps (20121011 signed, hard to find the correct version for this Lenovo S820e )
Video: https: //youtu.be/ yhIwf3OHAUU
Can I post a youtube video please? I have uploaded a video with my problem. Help me please. Got denied access because I'm a NEW member here.
I need help, if someone have seen something like this "assistive touch-thing" and know how to uninstall / deactivate it will be great and I will pray for you :fingers-crossed:
I don't know i I'm too newbie.
Sorry if I have grammar errors or bad english. I'm not native.
Thank you in advance.
Best Regards.
New to here to share some thoughts: why is it so hard to run an emulator on PC?
Reasons of variety come to my mind, but I mustn't tell so. Just done days long of experiment and all in vain, here's my steps in summary:
1. Installed OpenGAPPS. Failed at starting Play Store. (Unfortunately, Google Play Store has stopped.)
2. Installed an unidentified Dell x86 version of Phonesky. Worked for a few minutes then stopped.
3. Installed Lucky Patcher site's Modded Play Store. Stuck at "Authorization is required. Please log in to your Google Account" message.
4. Init.rc trick: ramdisk.img successfully patched, adb shell always root without a need for adb root command anymore, but SuperSu simply didn't work at all.
5. Started from 27/01 and gave up on 28/02.
This thread is probably a collection of my emotional techie notes. I may reply if anyone asks for a laughter on the methods I used. It's OK. Ain't a developer, but ain't a normal user anymore.
At last, greetings to all! Hope I can learn more in the future from xda forums!
