TCL TV 55 inch L55C1US [5.1.1] Root - Android Q&A, Help & Troubleshooting

Hi everybody
I bought an android tv was very enthusiastic about how the rich 4k resolution combined with an android system would be well this is running 5.1.1 im lucky to say that it came with an app store from which I installed Google Playstore the Playstore sucks but im making do with what I have then I pushed some apps using ADB specifically apps to root my TV yeah you dont find many threads about rooting these things since they're rather not mainstream but having that said something weird happned no one click root app worked on my tv not kingo not king root none of them i tried 10-15 different ones until i downloaded ES file explorer and started looking around in the system folder i found a file called 'tclsu' then I went on my computer hooked it to my tv using adb
then i typed in 'adb shell' once i was in shell i had the $ sign when i typed in 'tclsu' and hit enter I got a # sign which meant i was rooted i was so excited i put a superuser apk in my system/app folder but it wouldnt find the binary and said i wasnt rooted i even changed and set the right permissions 4755 using chmod with # i moved a new binary and tried to do alot but i cant seem to make Super user work only in shell i can move files using 'tclsu' and going superuser shell how do i get a full root so i can do other things!?

I have similar TCL TV 55 (LEDP110US). I am facing the same problem. I was not able to root it yet as well. I was able to access the secret hidden factory menu and also connect to adb.
Also I have the .bin firmware file of my tv which I got from TCL directly.
My thread is here: https://forum.xda-developers.com/android/help/tcl-tv-55-inch-l55c1us-5-1-1-root-t3565932
If you have made any progress please share.

[Q] Am I Root?

I installed Z4 mod and ran it and it says my g-tab is rooted. I have read that custom ROMS are pre-rooted. In my limited linux experience - being root gives you total control over the machine. I ran Terminal Emulator and cd / to get me to the top of the file structure. I tried to mkdir test and I was denied because the file system is read only. Next I went into the system folder because a lot of stuff in there looks familiar. I again tried mkdir test and was denied because the file system is read only. It would seem that to be root I would need a password and Z4 didn't offer to give me one or let me set it. Thinking further, I wonder if the file system is mounted for read only and that is why I can't create a new directory. When I am running the rom (Vegan) I can write there (understanding that I am writing to the sdcard that is mounted - presumably with RW access. So, what is all this rooting talk about then? What is the purpose of being root if you still do not have access to the file system?
You need Superuser.apk, as well. Think of Superuser as similar to Windows UAC, and rooting as making yourself an administrator. Even though you have root (admin) access, UAC (Supeuser.apk) still needs to let you through.
You also need "root aware" apps. Perfect example is Titanium Backup and that's usually my "litmus test" for verifying if I really have root or not on a device.
yup, in my limited rooting experience (droid1 and gtablet), after the process, there was always a new icon in the app tray entitled "superuser". i didnt have to install it separately, it showed up after the rooting process. if you don't have the superuser app, im betting the root process was unsuccessful.
my memory tells me i had some problems with z4root rooting my tablet, and i had to do it a few times before it actually worked. that was back in december tho, so i dont know if the current version of z4 is different than the one i used, and if so, if kinks were worked out...
so yeah, i probably helped none.
I always though z4root and Superuser were kind of a package deal.
I use them on my Cowon D3, as Cowon completely locks down their recovery process. boo to that.
rodzero,
With z4root you install it first. Then, you install a file manager program like "Root
Explorer" and when it comes up you click to "Allow" it. After that, you can go in
through Root Explorer and create and change R/O to R/W as needed. Same same
with Titanium Backup, once you have "allowed" it you can do what you need
to with the program.

More Investigation.
Thanks for the fast responses! I do have Superuser installed and it pops up from time to time when an app wants su access. Using terminal emulator, I worked my way into and what do I find but su! I ran su and got was granted su rights in the terminal. I felt pretty smug so I headed into the etc folder thinking I would make a simple change to the hosts file just to see if I could do it. I'm used to using nano in Ubuntu but no nano here. I tried vi (which I really don't know how to use) and I got some strange display but I don't think it was an editor. So, for the sake of closing the loop - if I wanted to edit the hosts file and add a new host - how would I do it. The Terminal Emulator now seems to be in the list to be granted su whenever I type it in. I know how to move around the file system. What kind of text editor would I invoke to actually alter the file? OK.... I went and downloaded TED and worked my way back to the hosts file, added a line but TED doesn't have su rights to save the file. So it looks like su exists but I don't see how to run an app in su mode except for terminal where I can invoke it by a text command. What's the missing piece to get TED to ask for su access?
Just a guess, but TED need to ask for elevation of privileges. It's probably an app issue.

Huawei Mediapad / T-Mobile Springboard Discussion

It looks like we have to move our discussion here, so I went ahead and started a thread.
As of now, there is root for the mediapad, but the only way to root the springboard is by flashing it with a rooted mediapad cust.img - which gives you root but loses your 4g.
So for us Springboard users, we either need root or a way to get 4g back if flashing it as a mediapad. Anybody with thoughts or leads or any know-how?
Finally,
Special room for Huawei Media Pad created,
Thanks to TS
I'm very glad,
Now i'm waiting the master in here to modified this device
cause i still newbie
Actually I Prefer The 3G More THan The 4G For Some Reason I Felt 4G Wasnt Stable Enough....So Im Enjoiying My Mediapad In 3G More Than My Springboard In 4G......

Yap, only thing you have to do is install Superuser and Busybox from Market and copy "su" from /hwcust/oversea_hk/preload/fixed/bin/ to /system/xbin (e.g. with ES File Explorer with root and r/w enabled), and you are ready to go
I've installed SU & BusyBox. I cannot move the SU file over to /system/xbin. A message tells me that I am not root.
However, when I run Root Check Basic I am told I have root.
I ran Root Check before & after I installed S7-301u V100R001C232B012(Root_version) and Root Check said I did not have root.
So the real question is, How do I really know if I have root?
*****
Actually I installed BusyBox Installer. I'm asked to pick a version to install:
1.19.3
1.19.2
1.18.5
1.18.4
1.17.1
None of these will install.
I also have the option to install a "Custom Tune" is there one? I'd gladly pay for BusyBox pro to get BusyBox running
*******
I powered off the device. Put my sdCard back in (the rooted firmware was removed from it). Then installed the SuperUser update from the market.
Ran that - it said everything was OK. Then I forced it to update - it crashed - so I force closed it. I then realized I could not run the original SuperUser app anymore.
Next, I opened up Root Explorer and was able to move the su file over to the xbin. But now BusyBox is not acting right - It said that it was having problems installing, and I'd need to reflash (or reload - I can't recall) the rom.
I'm rebooting, and going to try to install BusyBox....to be clear on which BusyBox..it's this one:
https://market.android.com/details?...t=W251bGwsMSwyLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.
*****
Just realized in Root Explorer, to tap the little gray box at the top. After you tap it it should read "Mount R/O"
Now you can long press a folder/file and change the read/write permission.
Rumbi,
You said to r/w enabled the su file....is that check ALL the boxes?...Read, Write, Execute Special?????
IIRC, i had some problems with busybox, too. Copy the file from the attachment to /system/xbin and try the installer again.
And i said to enable r/w support for the /system folder. There are two checkboxes in ES File Explorer. First checkbox is enable root permission for ES File Explorer and second checkbox is "Mount / and /system writable".
Now you should be able to copy whatever file you want to /system/xbin. That's how i have done it. If you have any further questions, feel free to ask. I'll try to explain.
PS. You don't ne to alter file permissions of the su-binary but mine are "rwx r-x r-x".
Rumbi, how do you feel about the High resloution mode, does it slow the tablet down? Have you had a chance to use any tegra 2 devices and if so how does the mediapad with the snapdragon compare when in standerd/high-res mode?
Nothing to complain about the Hi-Res-Mode but i don't have any Tegra2-Devices to compare, sorry.
Haven't tried any games in hi-res-mode but normal usage is just fine.
Thanks. Ill try this out. When i try to install busybox it hangs first, then i force close and run again. Then i get the message about reflashing Rom. But i know i have root. I installed connectbot and ran su and got #
Heres how i got root (im away from my pc right now so i try to be as accurate as possible) :
Installed Hauwei modified rom (its the one that says "(root) " in the file name.
Installed Root explorer
Installed Superuser
Install busybox
Install Connectbot
Put my microsd back in (with the firmware AKA dloa folder removed)
I could not get root explorer to allow rw permissions until i slid the sd card out and back in whil the device was on.
Then i ran connectbot as local and typed su hit enter then superuser popped up asking fo allow connectbot to access. Hit allow an type su hit enter an you should get # This took 3 reinstalls of the firmware to work wjthout errors. The first times resulted in superuser needing to be force closed.
I also ran superuser and went into settings and updated it eventhouh its not neede. There i got a read out saying that busybox is not installed, but it does say i have root.

Honestly i havent noticed a big difference between high resolution an standard.
The only issue with high res is the small icons and buttons are difficult to hit sometimes

Do i need to unzip this file first?....
.... Nevermind... I unzipped it and put the busybox file in th system/xbin folder.
I installed busybox installer by JRummy16. This time and it worked!!!!!!!
Now its on to figuring out 4G and tryiying to use it as a phone.
What is the xml file i need to edit?
Sent from my HUAWEI MediaPad using xda premium
Good, that you have worked it out now What exactly do you want to do? To get to the hidden menu, you have to open the calculator and type: ()()2846579()()=
To edit the XML-Files, you have to extract the cust.img... But now that you have root, yo can edit whatever is available via root explorer
€dit: To get 4G working again, maybe with someone with an original Springboard (not a flashed one) can copy the folder /system/lib/. This should be possible even without root. I think it has something to do with the ril-files...
after updating my mediapad to S301uV100R001C232B012, i have problem with 2x Client (RDP client) now, few second after conecting to rdp session, is app 2X client crashing, with error 2x Client has stopped unexpectedly (process com.tux.client), is here anybody with this problem? thanks...

How about this - link
I'll look at it, thank you And these are the libs from an unmodified Springboard, aren't they?
yes indeed. I broke the silly thing, so I haven't played with it much. guess I will have to call about how to get it fixed.

Even though I have no clue of what to do with this, THANKS! I tried to open an .so file in notepad, but no luck, but I'm assuming that the geniuses here know what to do.
On an off-root topic - How do you take a screen cap? I accidentally did it yesterday while my MediaPad was lagging, but don't know how I did it.
The Hi Suite that comes with the device can do this, but require a computer and usb hooked up. Useful, but not as practical as doing it from the tablet itself.
The *.so files are a bit like drivers for the internal components. I'll try to find differences between T-Mobile and Huawei so maybe we get 4G working again.

I'm not sure how to screencap. It's so easy on CM that I've gotten lazy. Plus I rarely do it. I know there are a ton of apps for that, tho. But you could probably google "gingerbread screen capture" and find a better answer. But not with gingerbread. I'm blanking on the name for this version of android.

Honeycomb
I've been Googling searches like that, and end up with actual screen shots of Honeycomb os..I'll keep looking...
Tried this (from here), but no luck:
Screen capture
Android natively supports the ability to capture a screenshot by method of pressing both the power and volume-down buttons at the same time on an Android device. This native support was first included within the Android 4.0 (Ice Cream Sandwich) update, which is first seen on the Galaxy Nexus smartphone.[86] Previously, Android did not feature native support for screen capturing which would have likely been due to security concerns. Furthermore, prior manufacturer and third-party customizations as well as using a PC connection (DDMS developer's tool) were the only known methods of capturing a screenshot on Android.
I've looked through the *.so files and many of them are exactly the same, but some are different. One file caught my interest. I've attached it here for anyone who wants to try. Please only use it, if you have a T-Mobile Springboard with flashed root Firmware. Copy the content of the zip-file to /system/lib and overwrite the existing file. But make a backup first! After copying you have to set the correct file permission (rw- r-- r--) and reboot the tab. Hopefully 4G works again with this little trick.

Itomic IMID77T

anyone know anything about these tablets? It is a cheap brand from bestbuy, I was just wondering if anyway could help me to get the android market to run on it.. It is a custom Itomic branded rom, it only has swift market or something like that on it.. Also, the recovery is not a regular recovery. When I go into recovery it just shows Itomic on the screen and says recovery mode at the bottom.. Itomic BestBuy That is the link to bestbuy for specs on it..
TIA

Are you rooted? If you're not rooted then go here: HERE and pick up the latest SuperOneClick program to get you started. Once you're rooted you need to download the latest Android Market apk here: HERE. Put that file on the root of the sd card in your tablet and then use a file explorer such as Root Explorer to find the file. Once you know where the apk is located you can use an APK installer to install the file. Then viola! You now have the Android market on your new tablet.
Trust me when I say you want to avoid a resistive screen (no multitouch) and 256M RAM (slooooow) as I have a 10" tablet with those specs.
Its not mine, i would not buy one with those specs just for the reason of I am used to my evo, not the best phone, but I like the way it responds and I would want the same or better response from a tablet... This is actually my 10 year old cousins tab, and it did not come with the android market as stated above so I am trying to fix that... I am nervous to root it because it doesnt have a regular recovery so if something goes wrong I would not be able to fix it... So I am looking for a dev that has experience with this or a similar tab... If I knew linux programming Id be a dev but unfortunately I dont know and at this point in time I do not have the time to learn...
That one click root program won't hurt anything. I've rooted many tablets and phones with it and it works like a charm, no problem. Once you're rooted and get the market make sure you get rom manager and see if there are any flashable recoveries for the tablet.

I also forgot to mention I cannot get adb drivers to work... I have dev on and it still wont recognize the android drivers.. It is not the micro usb but mini usb, I have tried multiple usbs but it still will not find the correct drivers...
I dug into this and just found the tab came rooted, all I had to do was mount the system as rw through adb and then manually changed su to the gb su.. I installed root explorer and rom manager but unfortunately there isnt a recovery for it... I saw on androidtablets.net that a guy is willing to port cwm to any tab for you but am nervous to try anything because it is my cousins... I think for now I will just install the market and be done..
Yeah that would be the best since it doesn't look like it's too widely supported. But cm would give it a smoother feel and be a little nicer, but do what you choose.

Very often when you want to write files to a particular partition on ADP1, you will get a "Permission Denied" if the partition is mounted read-only.
To get around this, you need to mount the partition read-write. Typically this is done with /system partition
$ adb shell
$ su
$ mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
(Replace /dev/block/mtdblock3 & /system with appropriate device path and mount point, as obtained from cat /proc/mounts) quoted from: android-tricks.blogspot.com

actually I figured it out once I got a root explorer. Im able to find the su file, but not really sure what, if anything Im supposed to change. Once thats taken care of , how to I download the android market? Do i just find an APK online for it? Or is therre another program or something I have to go through. Thanks again, im learning...
Sorry its taken so long to reply, when i say I changed the SU in /system/xbin, I opened windows cmd and ran "adb shell" "cd to /system/xbin" "rm ./su" then "exit" still in the cmd i adb pushed the su file that i extracted from this file su-2.3.1-efgh-bin-signed.zip (thanks to goo-inside.me) with "adb push C:\su /system/xbin" I then pushed superuser.apk to /system/app with "adb push C:\superuser.apk /system/app" then "adb reboot" and when it turns back on you are fully rooted. now download gapps from goo-inside.me then extract the system/app from the zip you need to install GoogleServicesFramework.apk OneTimeInitializer.zip SetupWizard.apk Talk.apk Gmail.apk Vending.apk with "adb push *.apk /system/app"

Qualcomm mdp tablet APQ8064 root

I recently won this developer tablet and I can't seem to get on-device root access. It came with su binaries installed. (very old ones but I updated it) It also has an unsecured kernel because ADB always runs as root. However I installed superuser and it can't get root access and when other apps attempt root access something seems to be denying access before the superuser prompt is even able to come up. Just curious if anyone has any ideas??

This may seem like a stupid suggestion but I suppose you could try uninstalling the superuser app and use Chainfire's Super SU app to see if that might make any difference.
Tried that too lol. I was even able to go into old su app and toggle permission for super su to allowed and it still said fail when it tried to update binary. Thanks for the suggestion though. It seems to me the problem is that the chown and chmod commands are not sticking on the su binary. They appear to work but the actual ownership and permissions of the file don't change. Even when I do adb remount first.
I figured it out. For some reason I had to put the su binary in /system/bin instead of xbin. Which is strange because all my other device it went in xbin. Also the reason the chmod and chown commands were not working properly is because I forgot to do adb remount. (duh!) In case anyone is wondering this thing is a beast. I just wish I could figure out a way to get my Gameloft games to work. I (mainly modern combat 3 and nova3)

One way to get your games to work would be try side loading the Modern Combat 3 and Nova 3 APK's onto the device and installing them manually that way. Another way if that doesn't work is you could try modifying your build.prop and changing your product id to match the galaxy nexus that way the play store will think your on a galaxy nexus and it should say that the games are compatible then.

I know this is an older post but I'm at the same point where I can't figure out how to allow superuser access. I'm using the 8064 for research and I need the root access but can't seem to figure out how to update the SU. Any tips?

Do you have the Superuser.apk app installed along with the SU binary in the correct place /system/bin as mentioned by JBO1018? If you already had working root access before on the device and just need to update the SU binary you can open the Superuser app, then go under the info tab and tap on the SU binary version number this should then check for updates and then ask you if you want to install any found updates.

I have both the Superuser.apk and SU binary in the right place. Each time I open up an app that needs root access a toast message pops saying that the app has been denied Superuser permissions. I tried restarting both apps but its not working.

Try going into the Superuser app and under settings and then security the default behavior is set to prompt not deny.

[Q] Pyle PTBL102BCD tablet has only partial ROOT

Have a strange one I don't know how to fix. Purchased a Pyle PTBL102BCD tablet for the Mrs. to use basically as an ebook reader (according to About, running 4.2.2). When it came in I started sideloading apps to prepare it for her (I do not have a Google account), and searched on the Net about rooting the device. Found a one-click that worked with a different Pyle tablet, so I gave it a shot.
Now I have root access _only_ through the adb shell. None of the apps (including Superuser.apk itself as tested by updating /system/bin/su) can get root access, yet I have no problem running root through an adb shell - remounted file systems, even performed an su which is the only instance Superuser.apk's log shows. Root access in the shell remains between reboots, so it's not a temporary root.
If the adb shell has root, I _should_ be able to use it to grant access to everything else, and I've followed a few different "manual" root instructions (having different permission settings for su and busybox), with no joy. So long as I connect with a USB cable and type on the Windows machine, I'm god. On the tablet itself...not so much.
I hope that someone with a more intimate knowledge of Android internals can point me in the right direction for achieving root completely. Currently have Titanium Backup and ConnectBot (long java errors when I attempt to su there) installed to test root, Superuser v3.1.3 and su v3.1.1. Permissions on su are -rwsr-sr-x. And the human is confused.
Did you get anywhere with this? I have the same problem. What one-click did you use?

Side note; REALLY hate the new forum software. With all the untrusted Google and Amazon javascript (which my company firewalls), it's a pain for me to even log in let alone post replies. (And I wonder if I'm the only person in the world sick to death of all the unnecessary ajax garbage...)
Anywho, used Kingo, rooted and unrooted a few times, until I finally acquired complete root on the thing. Once I did, I could run Samba, and once that worked, I could more easily transfer files and apks to the tablet.
Still don't understand why it was left in such a...weird...state - having root by default in adb is just a scary thing!
thanks for the information. I tried doing that but I encountered various problems. Eventually, after trying to do it manually, I totally screwed up the device. Now it won't boot.. I still have access to adb. I need to flash this thing. Do you know what the stock ROM is?

No...I can give you the Kernel version info (3.0.36+ [email protected] #48) and build number (rk3168_k11_4.2.2_v20131230), but other than that no clue.
