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.
hi, is it conceivably possible to root a fone with something like connect-bot. since it's local command-line shell has access to the directory tree above /mnt/sdcard , couldnt someone download the files needed for the root to the fone via the web browser and copy them to the correct locations with something like connect bot ?
i am new to android so i am wondering if there is a hole in my theory ?
thanks,
Depends on the phone really. Some need to flash files you normally can't while OS is still up. Some, perhaps?
There are root deployment applications which can be ran on some phones

thanks, i wonder if there is a roster of files that need to be updated/ replaced for rooting a 'samsung galaxy s2 epic 4g touch by sprint' (i hate that name).
the reason why i ask is because since android has a perfectly capable linux command-line and file browser then there is no need for windows. (i managed to install heimdall on fedora but i have a suspicion that the apb just runs the commands as if it was run directly on the fone).
Most of the phones need to connect into PC usb port... unfortunatelly
The way of rooting depends on which android version you are using. Some exploits allow applications to get root privilege; others, like psneuter(2.1) or zergRush(2.3.3) work restarting the ADBd with root privileges by making it believe it's running on a test(rooted) phone.
On the first case, I remember an application called "Universal Androot", which I used to root my first Android phone, SE Xperia X10 mini, when using Android 1.6. That app exploited some security error on the system, and gained root itself, so I rooted my phone without need of a computer. Also, for 2.3 API Level 9, I think GingerBreak has an android app which does the same.
For the second type(the most common), it's necessary to use a computer, as the only way to get the root privilege once exploited is via the ADB console "adb shell". The other processes will remain running with their original privileges.
^ thx for the explanation. kinda' like you cant upgrade the kernal of a running system.
hmm that would be nice if someone sort this out..
Like Z4?
HTC Thunderbolt running MIUI
sort of, but more related to android security: exploits like psneuter & zergRush attack ADBd to make it run as root. other exploits, like gingerbreak, give root privileges to the application which run the exploit(somehow equivalent to running "su" on the terminal)

I've seen a couple of videos on youtube about doing a root on these pads. I have 1 coming during the week, here is some of the technical spec for it...
Real Android 2.3 system, Flytouch 3 upgrade version
CPU VC882 Embedded 800MHz~1GHz ARM Cortex A8 32-bit processor core
I'm not sure of the exact make.
Is it really as simple as it seems on the youtube videos i.e install LauncherPro and select USB debugging option, then installing z4root, and that will be the device rooted?
Also, I downloaded the z4root.apk file on to my pc, but would I be better just downloading the .apk file straight on to the tablet via the browser rather than trying to transfer it from my pc?
Also, once installed, is it possible to upgrade the OS from 2.3 to a later version?
Sorry for the basic noobish questions, and thanks for any help you can give :good:
So here's how I did it:
Basically, with an Cortex A8 processor, the Maxell C8 tablet seems to be a slightly upgraded Allwinner A10, which is a bit cheaper than the Maxell tablet but then again Maxell really did package theirs nicely in terms of casing. But it's no secret - when you plug in the Maxell C8 with Windows 7 it shows clearly that it's a MID tablet. So essentially, my theory is that this method should work on all similar tablets such as Allwinner A13,A10 etc (although many of those come with preinstalled google play, as China, like me, doesn't give a **** about copyright). For reference, my tablet is running Android 4.0.4
Step 1. Root your tablet.
This took me a few times to figure out but this program called "Android Root Unlock" finally did it for me. You can get it from Source Forge: http://sourceforge.net/projects/androidroot/
Enable USB debugging (settings > developer options > Usb debugging). Then just connect your tablet to your PC via USB, wait until Windows recognizes the device. It should read "MID" in the device manager screen. The unpack the zip file you downloaded above on your Windows machine and run "ICS_Root_Unlocker.bat" it while the tablet is still plugged into USB. A black terminal window will open, just follow the instructions from there. Your tablet will restart - that means it probably worked, don't close the program yet but follow what it says to the end until the terminal window closes. Now you can unplug your device.
Step 2. Install modded Google Play
Now you can go ahead and follow the instructions on xda-developers.com:
http://forum.xda-developers.com/showthread.php?t=1650116
That's it! Google play now works like a charm and I can download stuff directly from Google Play without problems
Here's my full blog post: http://truthtech0.blogspot.com/2013/03/android-maxell-maxtab-c8-tablet-market.html
Thanks for your efforts, I'll give it a try. I was going to try Root_with_Restore_by_Bin4ry, but as you've confirmed it works, I'll use Android Root Unlock.
I think it's running Jelly Bean, it's my dads tablet. I'll see him tomorrow.

Anyone managed to install either a recovery image or a custom rom on the maxtab?
I've rooted mine but cannot get fastboot to work and unable to load a recovery image. Adb is working OK. Tried clockworkmod but device is unsupported.
gadget19, what happened to yours, why do you need to recover or use custom rom?

Hi, thank you for your guide.
Unfortunately i'm unable to complete it because when i connect the maxtab c8 to a windows 7 system it doesn't find the MID driver so the root bat doesn't find the device.
Do you have any hint in how to complete the procedure?
Thank you.

Thanks for the hint; I was able to execute the bat file but i still have some problems.
The procedure looks like complete but if I open Root Explorer and try to do some changes in \system\app it just tell me that it's in read only mode.
Tried root check pro and it's all red...
superuser installed
sbin/su: permission denied
system/bin/su: no file
system/xbin/su: Setuid attribute present and root user ownership present. Root access is correctly configured for this file! Executing this file can grant root access!
system/xbin/sudo : no exsist
su binary not found or not operating correctly
Tried to run the su file in system/xbin/su as a script on the tablet and via adb without any changes. Checked a bit online but i'm a bit stucked since my other android device (lg p500) was much easier to root.
If you have any idea i't will be very helpful. Thank you.
Ok solved.
To easy root the maxtab c8 (android 4.1) i used the RK29 tab tolkit v1.3: easy and fast.
Now i have problem installing the play store...
I followed the guide but since i don't have any Vending.apk or phonesky.apk in system/app i just copied it without a backup, rebooted but nothing happened.
Need more testing.
Ok play store installed and working.
I didn't use the apk linked in the first post, i had to use this one instead: http://forum.xda-developers.com/showthread.php?t=1934441
The method is the same (copy in system/app, set the permission as rw-r--r-- and then reboot) just use the apk i linked.
Hope this help someone.:victory:
Hi all, what's the best drivers to use for the Maxtab C8

I used PDAnet software for driver instal on XP. Have no idea if it will work for 7 or 8.
Google it, i cant post URL
Finally got everything working.
Used my old Intel x86 XP Pro to root it
Then Google play installer.

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.

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 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.

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.

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..
