I came upon this device on Christmas (a gift from my girlfriend to her father) and wanted to root it and also install clockworkmod recovery, so I could mess with it a bit without bricking it. Since I found a lack of tailored guides for it, I decided to write this one, although I really did no actual development whatsoever. Normally I would be posting this on general, but given the spirit of this forum, I guess I'll just leave it here. Also, keep in mind I don't have the device anymore and am writing this from memory. If I missed anything or you have any doubts, please let me know (for example, I can't recall specifically the drivers I installed to make it work properly).
Please, please read the whole guide before trying anything, and if you are a novice user, just leave this be, I don't want you to turn your tablet into a paperweight because of my shoddy instructions written from memory and you probably don't need any of this anyway as there are no custom roms yet.
!!!DISCLAIMER!!!: As stated above, anything you do is at your own risk. I provided the procedures that worked for me on a Qilive 97r tablet, which is an Auchan branded ARCHOS 97b Platinum HD, so my step by step should work for all of you. There are probably easier ways to do this, and I hint at them in the guide, but beware I have not tried them and cannot vouch for them. In fact, I cannot and will not take any responsability if you brick your device following these instructions, correctly or otherwise. You do this at YOUR OWN RISK. You have been warned!
Rooting:
I followed this guide on Windows 7 x64 and it worked perfectly.
So thanks to dhigby for that. I would just like to make a couple of remarks:
When you get to step 7 (Installing Superuser by ChainDD), don't. Install SuperSU by Chainfire instead, Use it to update the superuser binary (I think a prompt shows up) and when asked, let it delete the "other" superuser applications, that is, the chinese one. Clean and easy, you don't need to follow any more steps.
Congratulations, you now have (english language) root!
Clockworkmod Recovery:
There is no specific recovery for this device. Fortunately, thanks to AndroTab.info, there's a generic version for 3188 devices that you'll see should work quite nicely, albeight with some caveats.
What works:
Nandroid backup to/from external SDCard (won't recognize internal)
Installing zip files should also work, although I didn't try it at the time, as the device wasn't mine and I can't since I don't have it anymore, but since it mounts system partitions perfectly well I wouldn't think there would be a problem. Try it at your own risk though.
Other things probably work, give it a try.
What doesn't work:
Internal SDCard access
Probably other things
Installation:
Now that you have a rooted tablet, installing clockworkmod recovery is easy-peasy. Go to developer options and enable USB Debugging, then make sure you have a working adb daemon (look it up) that recognizes your tablet.
NOTE: I'm not sure if I had to install any specific drivers for this to work, I think if so they were installed while rooting by the chinese app. Anyhow, here's the Rockchip drivers, you might want to try to install them if you can't get a connection: http://www.rockchip.nl/downloads/
Download the file RK30GENERIC_CWM.zip from here - that's the recovery.
Now extract flash_image and recovery.img from the downloaded file above to the folder where you have your adb and follow the following commands.
Push the files to /dev partition on the device:
Code:
adb push flash_image /dev/
adb push recovery.img /dev/
Then enter root shell, like so:
Code:
adb shell
su
Now flash recovery.img into recovery partition with flash_image:
Code:
chmod 755 /dev/flash_image
/dev/flash_image recovery /dev/recovery.img
Now power off your device. To enter recovery press volume down then the power button and keep them pressed until CWM boots. Voilá!
NOTE: The instructions above were adapted from here and all credit goes to AndroTab.info ; I posted these particular instructions because they are the ones I used and worked for me; there are other methods listed on that page which might or might not work, TRY THEM AT YOUR OWN RISK.
Backing up your original recovery (for warranty, if anything goes wrong, etc.)
To obtain a backup image of your recovery \ restore it back afterwards, follow this guide here. All credit goes to Originalas.
Don't follow it to the letter though: first and foremost, you need a working linux installation. If you don't have one, I recommend Wubi.
Then:
Follow step 1;
Ignore step 2 (it's outdated);
Follow 3;
Follow 4 - but don't expect the screen to turn on, it won't, just hold the volume down button for 10 seconds or so after plugging it in, don't press the power button!
Ignore 5, 6 and 7
Follow 8, but don't use the last command to flash the CWM recovery onto the device. This is because since it is a generic version, it relies on the original recovery kernel. Flashing the image like stated in step 8 would probably overwrite the kernel and result in no recovery at all (I might be wrong about this).
Do follow the last command to restore your own backup if you ever need to.
I am unsure if recovery dumps obtained in this way are device specific; I don't see a reason why they should be, so I'll provide you with my own backup:
ORIGINAL RECOVERY
Flash through any method of your choice, but keep in mind I haven't tried this on other devices, so, as you know by now DO IT AT YOUR OWN RISK.
Closing remarks:
There you have it. Sorry for not holding your hand through every step, but this is meant for people who know a bit of what they're doing, making it faster than having to look up and figure out all these things and quirks on their own. If you have any doubts don't hesitate to ask, but keep in mind I don't have the device anymore and don't know much more than what I have written here. I do appreciate feedback and corrections, and will gladly change the guide giving you full credit - if it's really urgent just PM me, I might not check this thread often.
Cheers!
thanks, works like a charm...do you have any news about updates\custom roms? I can't find anything even in the archos main site

I wouldn't keep my hopes up on custom roms. The software is really bad and what it does with the hardware is terrible. It's like a bunch of chipmunks put the code together by randomly typing into a keyboard.
That said, the likelihood of a new kernel to fix that is next to nil. However, since the ROM is as far as I can tell pretty near stock, you can get a pretty good experience from the device by installing gravity box xposed module. I also recommend trickstermod and changing the governor to performance, as well as some kernel tweaking if you know what you are doing.
Also, very important, limit the amount of processes running in the background to 3 in dev settings or change the used memory limit to something like 1.2 gb. It has 2 gb of RAM, but, as I said, the ROM sucks, the system eats away a full gigabyte, and it doesn't effectively kill background apps, leaving you with a sluggish device if you multitask.
Anyway, those are just some ideas, if you have some more or would like to code for this device, feel free to share Also, as I always say, give it time. You never know who is gonna get they're hands on the device and do something amazing with it.

hi and thanx for the answer
yes i saw that it's almost stock but crappy optimized...in the very first start of the tablet i had 1.8gb occupied by nothing and clean master always notifies me that 90% of the ram is busy...meh
maybe just a kernel will fix like you say but you know, android 4.4 will be a must (rockchip already released sdk for 3188). I am not a coder (totally zero) but i will try your suggestion...just a question about the performance governor, does it drain more battery?
i am trying to backup my rom but cwm is so buggy...first was impossible, now i'm stuck on backing up boot image
there is a twrp available for this tablet?
solved

I'm interested
please ROM stock
Hello, i need help , if somebody know where I can download original rom , and original installer, I will be thankful for that's.
Ok, so lets start with hello you wonderful smart people
I did something very stupid and I'm really hoping there is a solution to my foolishness.
I have an LG G3 LS990, I had previously rooted and all was well. However, I decided I would flash a custom ROM after staying up all night. And in doing so I managed to take the steps terribly wrong, and I formatted the phone completely.
Along with this, I didn't realize at that moment that the phone was being it's finicky self, and had decided not to register as connected through ADB, and only connect enough to charge...
So, I've looked at pretty much everything that has to do with unbricking an LG G3 and it seems that without USB connectivity, I am pretty much boned. But I still have hope.
Basically where I'm at now is, I can turn the phone on, but all I see is the LG loading screen and nothing else happens until the battery dies, if unplugged.
I can use the volume up + plug in micro USB to reach the firmware upgrade screen, but I am unable to make either of my computers (windows 8.1 laptop/windows 10 desktop) register that it's connected through USB.
From what I can tell, the volume down + power, release at loading screen, repress volume down + power method doesn't seem to do anything besides turn on the phone and freeze at the loading screen.
So what I'm asking, essentially, is: Is there a magic method of making my computer recognize my shell of a phone that I haven't seen? because once I can do that, the firmware upgrade stock flash option becomes viable.
Thanks in advance for any help you guys and gals can give.

Hah! I did this once not too long ago on another LG device. Easy to make a mistake when you're tired.
You'll need to use the key combo to get to TWRP (should be Power + Down). TWRP is capable of transfer through ADB and it will also recognize an external SD card if you put one in it. That would eliminate a few steps with checking drivers and such. So you can then move the ROM and Gapps to the internal SD card and install from there.

Thank you for the response. It's a surprisingly easy error indeed. Since I posted this, I figured out the key press you mentioned and have been trying ROM after ROM intended for my phone specifically, yet all of them will end one of 3 ways.
I get a black screen with itty bitty little text saying fastboot mode and restart.
I get everything ready and I boot up, it loads until about the wifi set up and then it will either freeze for a couple seconds and go to a black screen which requires a battery pull.
Or, I get a bsod with the options of volume up = dload and volume down = reboot.
So far I've tried candy5, CM 12.1/11, blisspop, paranoid android, cloudy, and dirty unicorn.
Not sure what I'm doing wrong with these. I use TWRP to wipe everything except external sd, install from there, reboot, and repeat.
I fixed it!! thanks to http://forum.xda-developers.com/sprint-lg-g3/development/rom-stock-zv6-base-odex-deodex-t2949087
this ROM is the only one I could find that worked. I'd still love to be able to upgrade to L but it seems like all of the 5.x roms crash during setup. Not sure what this is due to, but I have a working phone, so I'm not too upset by it.
If anyone has any info on why all the lollipop ROMs are having trouble on here I would appreciate it much.
Well it WAS fixed.... All was fine and well until there was a software update, I clicked install, it tried to reboot, and now I'm stuck in a custom recovery boot loop. I still can't connect to either of my PCs by USB and using my SD card to flash ROMs isn't doing anything now, just boots straight into TWRP every time, after full wiping and re-flashing several times now I'm really not sure how to fix this one.
Update:
Got past the bootloop from another thread on here which had a flashable fix. Now that I did that I'm actually able to use 5.x ROMs it seems. Currently working on Blisspop 3.5, once I get GAPPS to flash correctly, I think I aughta have a working Lollipop phone
Make sure you are using the correct TWRP for your device, having Bumped, as needed. Also, make sure you use the correct version of Gapps; it matters based on the version of Android your ROM is based upon.
Good luck and enjoy!
Good points. From what I can tell I have gotten everything to remain stable now. Blisspop 3.5 and the CM 12.1 GAPPs from http://wiki.cyanogenmod.org/w/Google_Apps seem to be the winning combo. The GAPPs that was listed in the Blisspop thread as the "best" seems to be the reason that my previous flash attempts were crashing upon boot. It might be one of the 86 different apps that were included in there rather than the simple 12 of the CM 12.1 GAPPs.
Either way. I've had no issues now except for the previous issue of USB debugging simply refusing to work. I have installed the latest drivers for LG devices and have tried every article's suggestions I could find on how to make my phone be recognized. I've also tried a few different root required apps that are supposed to fix issues of USB connections. None of them seem to do anything. I've also tried different cords, different plugs and different computers. But it seems like the only kind of USB recognition for my phone is when it's off it can charge. It won't charge while it's on unless I've charged it a minimum of 2% while it was off (regardless of the current battery level) and it can't be recognized as a USB device at all.
Any advice for this? Thanks in advance.

It seems like the trend with ROM publishers is to not update some of those details in the threads; in the VZW variant, I know the BlissPop title still reads 5.0.x when they have been on 5.1 for some time.
I have tried a bunch of packages and have been using the Slim Gapps zero package + the DPI mod for a while now. They work great; there is even a tutrorial on how to roll your own if you like to have somewhere between 12-86.

Some troubleshooting questions:
I think your OS may not supported for Android SDK. Have you ever had it recognized on these machines through ADB before? Windows takes like 5 years to get to the point where most of the drivers work.... I know it's possible in Win7 at this point, but I wouldn't expect it to work in 8.1 or Win10. Someone else who uses it may be able to help with that.
What are the driver's requirements? These are more variables associated with Windows...
Have you enabled USB debugging in the ROM, via the Developer menu? Many ROMs still have this hidden by default.
What version of the Android SDK/Studio are you running?
Have you added the platform-tools to the SDK, as required?
Can you get ADB to recognize the device when you connected and are in TWRP?

Thank you for the response. I have noticed that a few small things are not so frequently updated in the copy/paste updates of the ROM threads. But that's to be expected =P Anyways, to answer your questions:
What are the driver's requirements? These are more variables associated with Windows...
I'm not entirely sure about this one. I know I found the drivers on the LG website for my LS990 model and I also installed a few others including older/latest/various models to test if any of them would work. I'm running windows 8.1 currently and the ls990 seems to have a little less support as the PC suite for LG doesn't include this model in their driver list.
Have you enabled USB debugging in the ROM, via the Developer menu? Many ROMs still have this hidden by default.
Yes, it's been a long running issue on stock, stock rooted, and blisspop all with debugging on. I was able to connect to both of my computers for a long while until one day it just stopped. It was much worse than it is now. For a few days, then it decided to charge up to about 4% when I plugged it in with no battery and then put the battery back and waited for about 3-4 hours. Then I could turn it on long enough to selectively power down and it would then charge while powered off. Over the past couple days I've been able to plug it in and reboot to get it charging again... So bothersome. As for USB debugging, not sure when it stopped exactly but I assume it was around the same time (2 months ago)
What version of the Android SDK/Studio are you running?
I have the latest version of android studio from their website.
Have you added the platform-tools to the SDK, as required?
Yes, I believe so. I'm not 100% on the SDK stuff.
Can you get ADB to recognize the device when you connected and are in TWRP?
No. There is no response from my computer at all during any of the stages of driver and twrp and studio installations. Nothing is listed in my device menu either.
Beyond this, today my phone ran out of battery while I was out and about and then has refused to charge by any method. Then I finally got it to turn on to power down etc so it would charge about 3 hours later. Once I was able to boot back up I went out to smoke and came back to my phone somehow automatically flashing a different version of blisspop that had something about user_modified in the file name which then unloaded all of my saved layouts and whatnot. After about 20 minutes of reorganizing it went black, and has since been locked in a bootloop which has survived full wipes and re-installations of the previous version of blisspop I had been using. I just downloaded the latest version for ls990 once more, and I'll report back with whether or not that fixed the issue at hand.
Hello,
I bought a second hand SM-T805 tab, mainly as a multimedia reader. The device itself is great, but the software turns out to be a real downer. So much uneeded stuff just sucking up battery time. Thus, I'm wondering what can be done to alleviate that. I'm fairly experienced with linux, recently hacked a zyxel nas to boot a custom debian, but a complete android noob. I mean come on: where is my console ?
So good advices are very welcome
For an instance, would it be possible to run a clean and fast kernel on that device, offering all drivers (cam, sound, touchscreen and so on), with a speedy interface, console command and nfs/samba support ? How about a stock android only patched with samsung drivers ? What would be the drawbacks compared to stock samsung software.
Than comes the question how it's done. Are there any complete guides on this forum about flashing an sm-t805 ? Any reasons why I should think twice about doing so ? Would it be possible to return to stock samsung afterwards ?
So many questions! Thank you for your help,

- console command: you can use Terminal Emulator app.
- you can always return to stock by flashing stock firmware via Odin.
Thank you for your replies. I found this page: http://forum.xda-developers.com/galaxy-tab-s/general/index-galaxy-tab-s-t3149566 It seems to sum up the possibilites offered on xda-devs for the sm-t805. Yet still miss documentation: why would I do what, how does the samsung stock software work and so on. For an instance, I got a cheap sd card - can't I boot to it and install a custom OS there, why leaving the stock rom untouched ? Flashing is always a tricky operation, which I would not recommend unless really necessary, especially when other storage medium is present.
Need desperate help with a MediaTek clone of S4
Hi everyone,
I will try and keep it short but last night I was badly scammed by a wonderful specimen of the human race, who wanted to sell his old Samsung S4. Turns out:
1. Its a mediatek clone
2. It has more issues than anticipated but all buttons work.
3. Seem to be soft bricked
Now I am facing nothing but patience to try and fix it. What works:
1. All buttons seem functional.
2. The phone boots into normal mode where I have only empty screen with a Phone app. The Phone app opens I can enter digits but cannot dial.
3. I can reboot into Factory mode - I performed all the tests of the device and all were a PASS. I heard the sounds, checked the cam, everything seems to be perfectly working. Touch scree, camera, sound etc. Even noticed it had FM.
I tried booting in Download Mode - no success. I get the dead Android image and it just hangs there. I can easy reboot though.
My PC recognizes the device and opens a media (empty) device folder.
I tried thus far to use SP Flash but....I dont know how to. Nothing is happening.
Of course I spent 6 hours waiting on different stock ROMs for S4 before realizing its a MediaTek device.
And now, here I am desperately asking if anyone could help me, if there is a chance to remedy that situation of mine. I dont need the phone to do anything special. The closer it is to a Samsung Android ROM - awesome. If its other, I dont mind at all. So long as it works and has access to Google Play Store.
Thank you geniuses and wonderful people for any hint you might have.
Hi
I had a similar issue couple of yrs ago with an S3 clone.
First thing u need to knw is the mtk version, memory details (RAM & ROM) and screen resolution to find a suitable OS version.
If ur lucky, ull get the stock ROM from the manufacturer on Google or else ull hafta search on xda, needrom, or the Chinese forums. Most of such devices don't have a lot of development so ull hafta port ROMs so a custom recovery will b helpful
Hope these points help

Ok.
So I need:
Device RAM
Device ROM
Mtk Version
I think I can extract these from the Factory Mode. Will check.
Then I need to get the stock ROM (hopefully) or search for a custom ROM. (Manufacturer I suppose we talk about MediaTek and not Samsung?)
Custom Recovery - yeah, usually this is the first thing I install but how do I do this on a cloned mtk? I suppose ODIN wont work. Can you lastly point me to a link or name of software to use instead of ODIN? (or will it work with ODIN?)
I've been trying to figure this out for a while, and I have made some headway but I think I need to make custom build. If anyone could point me in a direction, it would be super helpful. I have a few ELO ESY15i1 android computers. They are EOL now, and only supported up to kitkat. ELO does not release their kernel source, but I do have their peripherals.
This is how far I have got with this thing, and what I was able to do/determine.
After a bunch of digging, I'm pretty sure that this thing is just a modified S4 i9505. Hardware specs seem to match, outside of the CPU only being 1.7 instead of 1.9ghz. I'm *assuming* that they have down clocked it maybe? The first unit I was working with, apparently had a bricked recovery (had bough it 2nd hand). I was able to boot it into TWRP using the jfltexx image, but I would get no picture. I know it was booted because I could access TWRP via cmd, and it was giving me responses back.
I was able to root it in a very round about way. Since I do not have any volume buttons, I'm limited to adb etc. I was able to root it with iRoot, convert that to supersu, and eventually get flashfire to install. I could finally access almost everything I needed. At some point, I got it stuck in a mode where "QHUSB_DLOAD" was shown to me, with a folder called "image" which I took a copy of. Any google results with that, was just people who had bricked their device, I was able to boot in and out of this, so I'm not sure what was going on or broken.
Here is what the device props listed out: hXXps://pastebin.XXX/FtgQ0DUE
This is the mobilodin report: hXXps://pastebin.XXX/BZrDAFg4
Finally, the "image" I copied: hXXps://anonfiles.XXX/lcQ7RfJ8o0/ESY15i1-image_rar
(sorry can't post links)
The first unit I was working on, I gave to a buddy to mess around with. The 2nd one I have, I have now bricked and it is officially stuck in the "QHUSB_DLOAD" mode. I made a poor choice, and modified the i9505 "updater-script" in lineage-17.1-20200723-nightly-jfltexx-signed to include my "msm8960" device. I flashed it via FlashFire which did go through, just bricked me in the process.
I had a samsung download jig, but I can't find it anywhere, so I have a new one on order. I'm too lazy to cut up a micro usb plug and make one. I have yet to get odin to recognize it at all, or get it into download mode. When I try over adb, it will reboot, try to go in some mode, then reboot again back to the rom.
Any input / help would be greatly appreciated. These machines are super cheap on ebay, the only problem is being stuck on kitkat. I can think of loads of things to use these for, doesn't look like anyone has tried to do anything with them. From all my searching I just found one guy who was trying to root one, and that was about it.
Hi,
I have one 22 inch unit, which I'd like to use with monitoring system and some else, but I need android version with multi windows support, so I'd like to ask you if you succeed with installing new ROM ?
Thanks in advance for reply

Well, I've been dinking around with it again, I think I have the HW figured out. I'm pretty sure it's an LG Optimus G, LGE970 is what I'm trying.
I was able to take the stock "ATT-Stock-E97020j" non KDZ zip, pull the boot.img off of it, and flash that.
Now when I connect to my computer, I'm getting LGE Androidnet for Diagnostics, and LGE Androidnet USB serial, as 2 devices.
Just keeps hanging right away when I try and flash the KDZ.
