I am a c++ programmer by trade who is just now looking into android phones not only for communication but also for development. I picked up the Samsung Galaxy from Boost Mobile in order to first learn how to root, flash ROMs, and then get into dev.
My first goal is to root the phone so i can use it as a wifi hotspot. I first tried to download quick settings to see if i could get the wifi hopspot that way. I can see the hidden option for wifi hotspot but everytime I press it to turn it on, the phone disables the wifi totally. I then tried z4root, not root. I tried gingerbreak and it did not work. I would try to use superoneclick but cannot find usb drivers that will work with the galaxy prevail while its in usb debugging mode.
Any advice on how to get this phone rooted would great. Can you also list the prevail as one of the device supported on this site to spur development?
Not sure if you've come across the Prevail source code, the file name is SPH-M820_OpenSource_Froyo.zip
I can not post an actual link because I'm new to this site, but you can find the file here:
opensource dot samsung dot com/reception/reception_main.do?method=reception_search&searchValue=m820
replace "dots" with a period
I have not been able to get mine rooted either, but I did find these drivers seem to work for the phone with win7 and xp.

Try Z4root app I think this might work considering there arent any nam locks on this phone go to 4 shared and look for the apk files as this app is no longer available in the market! I have used this app on the following devices, htc hero, sprint zio, samsung moment, droid 1, droid 2, &droid global!
I tried Z4Root it did not work.
recovery mode
recovery mode is vol up + power
says
Android system recovery (3e)
EATH /data/update_sucess
E:Update logfile dose not exsist
#MANUAL MODE#
navigate with vol keys and camera button to select
z4 root and super one click
i tried z4 and the app closed at acquiring root shell
super one click also failed with psneuter and ginger break
fails at running psneuter and at running gingerbreak
also fail with shell root in same way
unrevoked
ps the unrevoked roots just do not detect the phone
odd recover style screen
if you hold down vol + and vol - and camera then tap power a screen comes up that starts with little kernel
vol - and camera makes the phne show "downloading..."
this is shown in windows as "samsung usb compsite device"
and "samsung mobile modem"
on linux
dmesg output of the "downloading..." screen

i have tried all known roots to my knowledge: z4 (rageagainstthecage), psneuter, and gingerbreak. none work. so im with you, out of luck.
same here i tired a bunch and no luck
I've been trying too, no luck at all, been at it since last Friday, but my knowledge is not nearly as good as most of you, so I assumed I just didn't know what I was doing.
I tell ya, I'd love to see root on this thing. Sweet little device. Greatly appreciate all who are working on this task
I have not found a way to root this phone but i did accomplish USB tethering. Install Samsung Kies (for usb driver for prevail), install PDAnet on computer and phone, and away you go. I am looking for a windows 7 bluetooth driver for the prevail that way i could tether via bluetooth DUN. Does anyone have any success finding a prevail bluetooth windows driver?
how to root
Is there someone who can direct me to a good place on how to develop the root, I would be willing to spend some time working on this. In particular is there any work that I can do to help a developer to create the root.

I wish google could help for that lol. I want to move my apps from the internal memory onto a sd. 164mb internal memory come the **** on
Any1 root this thing yet??????????
Same experience here, z4root required phone reboot as it kept setting off the vibrate function (permanent root) and eventually locked up the phone. z4root temporary root didn't work either. SuperOneClick failed as well with both exploits and locked up on Windows 7 x64 while running exploits. Can't find any information on Google. However, I am a 4th year Software Engineering student and would be willing to work with others to find a fix.
The Samsung Galaxy Prevail is a pretty cool little phone for the money and worth the exploitation effort. For those interested in working on this issue with me know that I am both a Windows (7 x64) and Linux (Slackware x64) user with a Java programming background. Look me up (email) on my profile.
From what I understand... We'd have to set up a rom manipulation environment (cooker?). Unfortunately the only tutorial I can find is the one for manipulating HTC roms. I'm not experienced enough to know if it could be used for all Android roms and too much of a chicken to try it out and risk bricking my phone.
Once the rom manipulation environment is set up you can go and add root support, take out unwanted apps, etc.
I'd also be willing to put in some effort into learning this if someone is willing to put in some time to show me the ropes... or point me in the right direction.
I need help figuring out how to root a RCA RCT6077W22 tablet. It has Android Jellybean 4.1.1- v1.0.1, 8GB built in storage, 1GHZ processor, Google apps installed, kernel is [email protected]#132.I'd like to try to root it from the tablet itself if not I'm familiar with SuperOneClick as I've used it for my Samsung Galaxy S 4G before I should it. If it comes to that option I need to be able to use a rooting program on my computer that does not require internet the only internet I am able to use is the libraries. I have a laptop but no charger so my laptop is dead. I'm not a noon when it comes to rooting as I've mentioned I've done it before. Just need help finding a root for this tablet. I appreciate any help I get and thank you. If you need more info feel free to ask. I've also looked at the topic about the 4GB but its not that helpful is why I created my own topic.

Did u figure out how to root your rca tablet....I have one and I need mine rooted also I can't store any apps on my ad card
Can you give more specifics such as the the model number, what version of android is it running?
Sent from my Nexus 5 using xda app-developers app
I have the rct6378w2 RCA 7' 8GB tablet (4.2.2 JB). (Black Friday 2013 Walmart for $49)
I was able to root it by first installing the pdanet drivers (for adb access). And then using the kingo app, which you can get from http://www.kingoapp.com/.
Its free but closed source. I found it via this youtube video. https://www.youtube.com/watch?v=8MiZtZCqu4k
Worked even with the 1.0.2 update installed (which I have no clue what it did (17MB).

I cannot get pdanet to get the drivers. I cant find any drivers anywhere. Pdanet says to click ok after connecting, and it just says no android device found..I think there's an error box too.. I don't know how to fix it. I also have the tablet from the black friday event. Exact same one. Also, I have USB debugging on...
UPDATE: I found out the problem! The support files weren't in the root file I had the .exe in. I just moved the .exe to the same folder with the support files, and now I'm rooted and ready! Thanks!

how are you turning on usb debugging? I also have this tablet(purchased on black Friday from Walmart like everyone else) and mine doesn't seem to have that option anywhere. in fact, compared to the previous two android products I have, this device seems to lack ALOT of available functions. though I am capable of navigating a recovery menu at boot. but that doesn't do me any good for using pdanet. that seems to be my biggest road block. pdanet wont install because the onl;y way I can allow my device to connect to my pc with adp is using the adp updater in the recovery boot menu.

It is a hidden option that needs to be enabled. Follow this guide: www ninjaromeo com / enable-usb-debugging-developer-options-jelly-bean/
I just enabled this option on my Walmart BF 7" RCA RCT6378W2 tablet.
Sorry I had to mangle the link because XDA wont let me link external sources yet.
Glad I could help a few. Now, someone get on a functional recovery ;p
I have poked around a little at the stock recovery, backing it up, etc.. But am not brave enough to try and get CWM working on it.
I was able to use th Xposed framework for a few mod's no problem. Battery mod, reboot menu, hide navbar, etc.. But Xposed can only do so much.
Edit: I heard on reddit this tool also works for rooting. I have not tested it (already rooted with the other method).

I was not drunk when I made this post...I have the RCT6378W2 if you go to about tablet in your settings and repeatedly tap the build number...the deveolper options will appear...I fell out of my seat when i discovered this.
On a side note...if you repeatedly tap the android version...a cute picture of the android jellybean will appear. Try it.

1: Install drivers. Seeing as RCA does not provide drivers, we had to find some that work. That's where PDANET comes in. Their drivers support a very wide range of Android devices. We are not installing it to tether. We just want the drivers it provides. So download PDANET, install, let it detect your device, install the drivers, and then afterwords you can uninstall it.
2: Enable Developer Options. Settings>About tablet> Tap Build Number a bunch of times till it's enabled.
3: Enable USB Debugging. Options>Developer Options>Click On (up top)>Then checkmark USB Debugging
That should clear up some of the confusion in this thread. How you root after step 3 is up to you. Personally, I did it with Kango. Which was straight forward. Connect device, hit a button, Say yes to a couple questions, reboot, presto done.

Thanks, that sorted things out.
To make clear, and aid in any other inquiries, I managed to find an ADP connection mode, among other android update features. with the device off, hold volume up while turning the device on. it should boot to an image of an android with an open chest panel and the words, "no command". if you push volume up again it will provide you with options and instructions on how to execute. you can manual update the device with an SDK through USB ADP mode this way. I'm not sure if that makes anything simpler or generates a work around but I hope it helps with future development for this device.
Well got root now we need a recovery...
For some reason when trying to make sure I can send adb commands to my tablet, I am showing no devices connected. I check in device manager and it shows up as Android ADB interface for the tablet. These drivers were installed with the latest version of PDANet. Thoughts or how were you all able to get the drivers fully loaded and working? I have developer options already enabled and USB debugging mode is checked.

You need to create "adb_usb.ini" in "Users>Username>.android".
Inside "adb_usb.ini" insert "0x2207" and save.

I had this problem too. make sure you're using the most recent version of pdanet. for whatever reason the older version just hang there and dont work right.
Installed the latest pdanet. It wont install the driver. I checked the device manager and it still shows the device without the driver. not sure what else to try..
I recently got one of these, I imagine quite a few people did (sale this year on em), and could find no documentation on how to root it. Hopefully this hits google and will help all the other users out there! I did not make the software but gave it a go and it worked fine.
How to Root your Nextbook NX007HD
Google and download Cydia Impactor (First result on Google) Extract it (desktop, wherever you prefer)
Enable USB Debugging on your Tablet (Settings > Developer Options > USB debugging)
Plug up your Tablet via USB, do not turn usb storage on, let windows try (and most likely fail) at installing drivers.
Launch Impactor and select USB Driver Scan from the top menu (under USB). Let it do it's thing, reboot your PC after.
Verify your tablet/android device is showing up on the start-bar as being plugged up/in (bottom right area)(this may not be needed depending on your setup)
Relaunch Impactor (if rebooted ) and hit the Start Button
Let it do it's thing.
You should be rooted :victory: now go install SuperUser!
I should additionally note in my experience the SuperUser by ChaindsDD does not properly catch/work, but the one by CWM does.
Hope this helped everyone out who was slightly concerned when they couldn't find a root method someone else had tried/verified!
Thank You
I got the NX007HD cause it was on sale, before needing this one I head bought a tablet Craigslist and it WS already rooted.
I have never rooted before and tryed the one click root which didn't would and came across this and after spending all day trying to root it with or help it was done in under 10 mins I can't thank you enough.
P.S by any chance cukdu tell me how I could change the start up screen?

Hello dannybz,
Last weekend I was able to install many apps on my niece's tablets, (Angry Birds, Hay Day, Google earth, Ninja Fruit cut) :good:
After rooting the tablet with the great instructions you found here, you have to install an app called: "Market Helper" and follow the instructions...
codekiem.com/2013/02/13/market-helper/
Then you can install many apps you want...
Hope it can help you... It helped me a lot.
(I did this on 2 tablets with Android 4.1... the original version that comes with the tablet)
Can you provide a dump of original rom for this tablet?
Been trying to get a hold of it since forever.

Hi, I need help on rooting my Hip street Phoenix tablet. I'm very new to android so I need lots of help.. Thanks.
Hello?
Anyone
Kingo root worked for me
Kingo root got stuck on Waiting for device...
I couldn't get it to work until I deleted android USB devices and then installed the android SDK, drivers were recognized before the SDK but kingo root wouldn't run until I did the SDK thing
I also have the same model(Hipstreet Phoenix), and I success on rooting it. for kingo root maybe check if you had enable USB debugging,
if it still does not work, then try install king root(is not the google play store,
download link:res.kingroot.net/msoft/webapp_kingroot/image/KingRootTrunk_105001.apk
1. download it than install the apk
2. open it(the only issue is the main screen and intro is in chinese, english video link:youtube.com/watch?v=Kzv75LQ1SlQ
let it install the root component(if is not rooted yet), on the upside the rest of interface is in english(including the request for root permission window)
and sorry about the links being in plain text.
hopefully this help.

Hello,
I bought for my kid Q-MAX (unknown brand) M755 KID tablet. It seams to be the same as the one by the Beneve brand.
1. Google Play starts with the window "no connection". I tried removing cache, installing new one from the apk, changing the date and time, location, but nothing works.
2. Then I found solution that requires root. I tried towelroot but it does not work on the device. For another rooting methods, I need to enable USB debugging and root it from PC. I have found oneclickroot.
3. Unfortunately, Windows does not recognize my tablet. It displays that it is M755 KID (i can transfer files, but there is a yellow triangle with a ! in the device manager).
I even tried factory reset (I added my account several times), but that does not work either.
Help? I do not know where to go next.

Yellow triangle in device manager, means drivers are not installed, could try installing generic adb drivers
see [Guide] Install drivers for any device using Pdanet by droidiser
Universal Naked Driver Solves Your ADB Driver Problems on Windows
There are several root methods here. http://www.xda-developers.com/root/
Google Play starts with the window "no connection". Check time zone, time and date.
Because there is not a specific forum for your device, this thread will be moved to general/help
I did manage to install the drivers in the meantime. It has rockchip chip, so somebody here: arctablet.com/blog/forum/firmware-development/rockchip-released-an-easy-driver-installer/[/url] gave the link to the drivers that work. Generic drivers don't.
I tried framaroot, oneclickroot, kinga root, towelroot and some more, all without success.
I did set date and time and time zone, but that does nothing. Automatic or manual, clearing cache...nothing - no connection.
The solution I have found is to write into hosts file: 127.0.0.1 localhost, but when I read that file, it has exactly that in it, so that does not work either. Maybe if I would delete the file, but I cannot gain root access.
So I am completely stuck.
