My only problem is the lack of a recovery menu in case something goes wrong in the future, because I don't have CWM and I can´t install TWRP.

Can you pls double-check with Nandroid Manager (Play Store) if the TWRP gets detected and you can reboot into it?

- Oma -

At the moment I can't install nothing because I have broken the screenCry, and until the new screen arrive I can only work with the buttons and the usb, unless you have an alternative solution...

I have tryed this command "adb reboot recovery" and the same problem happens, reboot to the black/blue screen.

Since TWRP is not working for me, do you have any alternative to installing the original CWM to this tablet.

Make sure you order exactly the same screen/touch controller, otherwise your stock kernel will not boot it!

CWM is also a custom recovery. Stock firmware comes with stock recovery which has only the functionallity to format the partitions.

Thanks for the link - the "README" instructions is quite extensive and leaves room for error. Might there be an easier way to dump everything? I wonder why rkDumper does not work but AndroidTool does. I don't think rkDumper uses ADB.

rkDumper is a very old tool and I guess it will not support RK3126. ADB driver are signed and I never heard about issues. Maybe your usb port is somehow defect.

Hi Oma,

RedScorpio just replied to me with a new experimental test build which is actually working for me. I just have a few questions about the rkDumper tool before I can proceed such as how I can use it to load only 1 partition if I want to revert back since it seems like it only loads nothing or everything.

So it is not a driver issue but rather something to do with ADB connectivity, not sure what it could be. Is there any way I can diagnose this with logging of any sort?

So the TWRP is working?

- Oma -

For me still doesn't work.

I flashed TWRP using THIS: http://crewrktablets.arctablet.com/?p=5038

with the same instruction included plus the parameter file enabled

I flashed that Twrp too, and it worked... yes...

I have the esp8089 version with #61 kernel

cheers...

Hello Erika, to have root on this tablet you have to use https://www.kingoapp.com/android-root.htm with a PC. After that there are tons of tools online to switch from KingoRoot to SuperSU (that work better) and to flash twrp. I advise against changing the ROM if you don't know how to properly do it. To transfer applications to the micro SD you can use https://play.google.com/store/apps/details?id=in.co.pricealert.apps2sd after you gained root.

Hi,

I'm having an hard time finding some information about another kernel version, namely the #61.

Is there any way to install a custom rom on this version on the tablet?

Here are all the information about the version I'm using.

Hello @Oma7144 and thanks for all the developement and support you're giving for this product rk3126x. I've succesfully installed OMA's rom for PlayTab3126 with ESP8089 chip and apart from the TWRP not showing the rom is working really neat. I'm just having 1 great problem that is tempting me to get back to "stock" rom: the Google account autenthication seems to have some problem. I use 2 steps authentication and all was working FINE with the stock 4.4.4 rom of this tablet (I've always used AOSP roms and never had issues on any of my devices). On your rom anyway I cannot access my account with Youtube and Google Photo (other gapps seems to work but always "asks" for permissions). I have updated play services and such... I've also tried a full factory restore to start again but the problem seems to stay.

PLEASE, this is driving me crazy!

Thanks

I have the same exact problem with the google authentication on google apps...

Anything I can do to fix it?

Thanks

Hello again, since I get ignored I would repost my question.

Iryon said
Hi all, I'm new here and I'm another Italian user who got this tablet RK3126 (NMC1000 WiFi) in promotion for 2€.

I got root permissions via Kingroot app (i can't obtain with "Oma_RK3126_Root_and_Dump" but i installed drivers early and done a dump lately) and now I'm wondering how to flash a custom Rom.

I read that "Oma_RK3126_Cube_U25GT-W4_KK_4.4.4_v1.0" should be compatible but I haven't read any feedback about it from other users.

I'm stuck in the replacement of the recovery because the phone is not recognized in fastboot mode, maybe lack of driver (and the tablet in fastboot mode has black screen), so RKAndroidTool can't find my device to flash the TWRP recovery of your post.

Any solution? Is a custom recovery required to flash a custom rom?  

Actually I'm on Win10 and I know this is not good for this modding so I'm trying to mod the Stock Rom. Now I'm running low on memory and I would like to know if there's a good script which can allow to use microSD to expand the internal storage (or if I can use microSD as internal). I remember about S2EXT app, D2EXT, INT2EXT, A2SD and other stuffs like that but it's been a long time since i used these in a Rom.
