Hey
I really want to try Ubuntu Touch.
I got the following tablet:
Zenithink C93
1.3ghz dualcore
1gb ram
10.1" 1024x600 screen.
I want to use Ubuntu Phone because my tab has not enough RAM for ubuntu tablet
It has a cm10.1 port, but it is not registered in Cyanogenmod, not even under unofficial ports
The computer i'm working at has;
Intel Core i3 530 2.93 GHZ
4Gb Ddr3
Hd6570 gpu.
Is there any chance i can port?
Can somebody help me with it? I cant do it alone
Thanks, Dominique.

any answers to this"?
I would like to bump this topic with the hopes that somebody will actually answer. I do know that it is possible but it's a matter of unlocking the bootloader so that you can flash with ADB. Would somebody please help us with this? I know for a fact that it's possible with Cortex A9 and the newer Ubuntu Touch builds don't require as much RAM.

i dont think this tablet actually has something like bootloader unlock.
i mean the stock rom is pre-rooted and has aokp settings.
just putting any recovery.img in a zenithink update folder, then holding power and back on boot will make it boot in the custom recovery, or any kernel named recovery.img
it could be possible, we have cm10.1, i can prepare my desktop with ubuntu and give it a try.
but the tab has no official cm10.x, how am i even going to start without the official sources?

There is an official porting guide at https://wiki.ubuntu.com/Touch/Porting and a mailing list for getting help. Unfortunately, there have been lots of changes lately and the porting guide is incomplete/out-of-date. Unless you are experienced developers using source code instead of documentation, I strongly suggest you wait, till the porting guide has been updated.

It doesn't and the recovery.img is a locked bootloader. When I try to use fastboot using linux terminal it is infinitely "waiting for device" I am currently using a 4.3.1 aokp rom and the author has been real evasive with me as to how to unlock the bootloader. I could upload the recovery image here if it would help or I could send it to somebody. What I was told by the rom developer was "the Amlogic kernel does not like mtp" which really had nothing to do with my inquiry.
Let me ask this...would flashing back to a stock rom make it possible to install Ubuntu as dual boot as seen in many current tutorials? I would post a link to one I have attempted to utilize but I can't post links yet.
Hello there,
I am looking for a Android TV box with vanilla stock android. Are there any available and for sale? I tried searching everywhere but could not find any. The reason I am looking for one is, because I am looking for a development machine and deployment machine for apps. The machine will have to work with different hardware (USB) and I will have to recompile the kernel and need to modify HID drivers anytime.
Most distributions on AMlogic devices make use of custom kernels and some modifications are just plain bad and half done, not to mention the half rooted quirkiness on some devices with modified rom versions.
So is there an TV Box like device available with clean vanilla android out of the box? I really hope someone could help me with my search.
Thanks in advance and really appreciate this community.
Hello friends! I have been reading a few different forums and sources regarding roms, but I had a few question to which I cannot find any answers to. I hope you all may be able to help provide me with some information.
I have read numerous forums with people who want to flash newer versions of android on their devices, or even revert back to their stock rom, but what about a custom rom that is a lower android version than what the tablet stock was ? Is that even possible, provided you compile it with android's open source code?
I have 4 lenovo tab 10 tablets - they are all painfully slow, and always have been. It doesn't matter if you clear the cache, disable programs, factory data wipe and reset, etc.
I understand that the reason the tablets are so slow is the hardware that it comes with - especially the 1GB of ram limitation.
For this reason, I wish to be able to flash kitkat on the devices to improve performance. I don't mind if many playstore apps wont run on the device, I just wish to be able to use it to surf the web and read a few e-mails. And believe me or not, the tablets in their current state can barely do that!
Anyhow, if I was to get the source code for kitkat, would I need to somehow port over the drivers from the stock firmware, or would this not be possible because the stock firmware is lollipop? I am having difficulty understanding if the kernels are related to the operating system version or if they can be used with different operating systems. The same is true for the "drivers", which I believe I had read are binaries?
Any help you guys could provide I would appreciate greatly! I don't care about building or getting a custom rom that has all sorts of programs and icon packs, I just want a bare bones kitkat install with chrome and google play capability to download a few minimal apps.
Thank you all for your time and help, and I hope to hear back soon!
Hi,
I've had this tablet for years and it got to a point where it is just paperweight (even Skype is broken for the version of Android 4.2.2. that is running). I've looked through XDA and internet in general and could not find any information on how to run TWRP or Clockwork Recovery Mod on this device as it is not officially supported. I have also not been able to find a suitable Android ROM. I've been particularly looking for Android 7 Nougat.
I have rooted the tablet using Framaroot (verified with Root Checker).
I have tried to install Clockwork Recovery Mod using ROM Manager.
I have tried to install TWRP recovery using TWRP official app and TWRP Manager.
I am aware of threads like https://forum.xda-developers.com/showpost.php?p=44660171&postcount=417 (How to install CWM on most rooted mtk devices) and I have not tried it yet.
Tablet details:
Lenovo IdeaTab S6000-F
OS: Android 4.2.2 Jelly Bean (Kernel 3.4.5)
Build number: S6000_A422_101_025_131017_WW_WiFi
SW version: S6000_130419
HW version: Lepad S6000-F
Chipset: Mediatek MT8125 (ARM Cortex-A7)
I have found some articles on the web describing how to perform the upgrade but they are all out-of-date, i.e. links don't work to ROMs and no information on how to install Clockwork or TWRP. Does anyone know how to go about this? Even getting Android 4.4 KitKat to run on this would be a big step-up.
@qumat
Because phone is powered by a MediaTek chipset, I think SP Flash Tool is the correct tool to flash a new ROM onto the phone, in conjunction with matching USB-driver provided by Lenovo for this phone.

Thank you for your suggestion. Eventually, I managed to make a full backup of the stock ROM. Hopefully that means I will also be able to flash the tablet with a custom ROM. However, I am unable to find any for this device. Are there any options left other than building a version of Android (LineageOS or OmniROM) for this device myself?
@qumat
I'm not a ROM cook ( developer ) but as far as I know you need the specific source code for that device to compile ROMs. What would require MediaTek / Lenovo has made it public.
Does that mean that there is nothing that can be done in this case?
I have managed to install ClockworkMod Recovery. Also, I found the source code for this tablet on the official Lenovo support website. I have tried to unlock the bootloader but regardless of what I do nothing happens. It seems as if the bootloader was not locked in the first place, there is no status displayed when I fastboot and none of the show version fastboot PC commands work. The PC connects without any issues, I can see the device ID both using adb and fastboot but unlock-related commands do nothing.
I now have the source code and installed ClockworkMod Recovery. Do I have everything I need to build LineageOS or OmniRom for this device? What is the best way I should go about doing it?
@qumat
Look inside Android's system file named build.prop for entry ro.oem_unlock_supported: This entry is set to "0" if flashing unlock is not supported on
the device or "1" if flashing unlock is supported. NOTE: This property is set by Android kernel.

There is no such entry in build.prop. In fact there are no entries that contain the word "oem".

Also no such entries. "default.prop" entries below:

ro.debuggable=0
persist.sys.usb.config=mtp
persist.service.acm.enable=0
ro.mount.fs=EXT4
I could not find any other default.prop or build.prop files on the device.
Hi qumat,
Did you get any solution so far? I am very much in the same boat in which you are. I also have Lenovo IdeaTab S6000-F and looking forward to upgrading the same.
My Tablet details are:
Lenovo IdeaTab S6000-F
OS: Android 4.2.2 Jelly Bean (Kernel 3.4.5)
Build number: S6000_A422_101_025_131017_WW_WiFi
SW version: S6000_130419
HW version: Lepad S6000-F
Thanks,

I have not yet. I have a feeling that the bootloader is not locked in the first place on this device, there simply is no mention of any bootloader lock anywhere on it. I have not tried compiling the source code from the Lenovo support site yet. Mediatek seem to be utterly awful at providing their binaries/source code so it is an infamous platform to do anything with. I (or anyone else) will have to try to compile it and check that everything needed is in fact there. If there are binaries missing then probably nothing can be done.
First I need to figure out how to actually compile that Lenovo source code...
Thanks for the reply qumat. I have always used the proprietary OS comes with the device itself and this is the first time I am looking for Custom OS. All the terms you used are jargon for me.
Request you to please keep posting here so that I and other users can also learn from your experience about the same.
Please share the links where have you downloaded the said software in your previous post about Flash,AWB and Source Code.
Additionally can't we build the latest android source code from the Android website, instead of taking from Lenovo. Is there any benefit of taking code from Lenovo?
In case somehow if I build the latest android code, would that work for the tablet? I have no clue, do you have any idea?
BTW, how can I check the Hardware used on the tablet, like you mentioned it is using Mediatek
Any Progress?

I also still have this device (using it mainly as a digital photo frame) after I learned that there were no custom roms available for it. I have managed to flash Superuser for root and CWM though, but that was the extent of it.
I am the owner of another one of those paperweights. It would make a nice ebook reader. If there is an update on this tablet, please post here.
Me too... I'ts a shame but I could not find any updates for it... :-(
I also have the same problem, Lenvo S6000-h looking for updated firmware, i am also very new to this. Has anyone found something for this tablet?
Hi everyone,
After a few hiccups, I successfully rooted my Leagoo T5c, thanks to the excellent tutorial posted here. The phone works fine, thank you, but now, I'd like to know how to proceed to, say, upgrade the phone from its current Android version (7.0) to a more recent version.
Where to start?
Since this phone has a Spreadtrum/Unisoc SC9853i SoC (Intel-based), I suppose the custom ROMs and upgrade possibilities are few and far between, but I'd like to give it a shot.
I'm open to ideas, tips, tricks, voodoo moves and Santeria incantations, but I'm still a noob when it comes to Android, so please, be patient, and methodical... :good:
@UglyStuff
If you can unlock phone's boot-loader then you should be able to flash any Custom Recovery and/or Custom ROM that's suitable to 100% to phone's CPU-architecture. Who is the supplier of phone's SoC isn't of any interest at all.
Hi,
Thing is, as I said, I'm a noob when it comes to Android, so I don't want to brick my phone by trying to make it ingest a ROM that's not suitable for it.
If my phone came with a MediaTek or Qualcomm SoC, I wouldn't worry, because there are plenty of ROMs out there, custom or not, to play with, but this Spreadtrum/Unisoc SoC is a thing of its own.
It's based on Intel's Airmont architecture, and few phones or tablets use it, at least this specific version (SC9853i). Maybe I just don't understand too well how a ROM is built.

For example, I found this article where they explain how to flash LineageOS 17 (based on Android 10) on a Panasonic Eluga Ray 800 that uses the same SoC as my Leagoo T5c.
The thing is, I don't know if this is transposable to my device, though the two share the same SoC. As I said earlier, I don't want to permanently brick my phone...
@UglyStuff
The mentioned Intel Airmount SoC's instruction set architecture is x86_64 , the also mentioned Intel Spreadtrum SC9853i SoC's instruction set architecture is x86_64, too. Hence in order to upgrade yor phone's Android you need a Custom ROM compiled for x86_64 architecture. GIYF ...
OK, but since this Panasonic and my Leagoo share the same SoC, they also share the same x64 instruction set, so do I get it right if I say that the custom ROM built for the Panasonic would fit on my Leagoo, or am I missing something?
In theory it should.
OK, I guess I'll have to chance it, and use recovery in case things so south. My phone isn't compatible with Treble, according to this app. Does it mean anything in terms of installing one of the generic system images found here or not?
