Regarding a custom rom

Hello everyone, I've been following this thread since I have an All winner A23 9" tablet and have been trying to get a custom rom on it, however I have no clue where to start (you can probably guess I'm somewhat new to the whole android modding)

But the firmware it came with I cannot put my hands on to which it is, it seems to be a mix between kit kat and jelly bean, and when I received the tablet it already came with a recovery mode option but had no system update option in the "about device" section, it simply had this "update" called "update" on my menu screen, but this checks for updates and returns nothing.

My question is how do I go about modding this or even a custom rom for it? the one on there isn't the best as it chalks up pretty often and feels a tad slow at times, any advice is welcome
[Android Q&A, Help & Troubleshooting] desarenezitic:
Hey, good to have you hear.

What more can you tell us about your firmware; can you list everything (or post a screenshot) it says in 'About Tablet', it should at least tell us what version of Android you're running.

Also you mention 'recovery option', is that just stock recovery? Have you booted into recovery? Are you rooted? These are all things we'll need to know before we even look at any modding.
[Android Q&A, Help & Troubleshooting] Emileh:
Just checked back and I'm super stoked there is now a kernel available!

can we use this to overclock?

anybody who's willing to give that a go?

(I might, but I know very little about it so I'm not expecting any results to be honest)
[Android Q&A, Help & Troubleshooting] desarenezitic:
There's no kernel available, as far as I know anyway.
[Android Q&A, Help & Troubleshooting] Mozelite:
Hi, thank you for the greeting - about the firmware I can tell you the following:

Processor:

DualCore-A23

Model Number:

GT90H

Android Version:

4.2.2

Firmware Version:

v2.0.9

Kernel Version

3.4.39

android5@Linux2 #90

Mon Jan 6 10:10:19 CST 2014

Build number:

polaris-eng 4.2.2 8089 20140106 test-keys

Also regarding recovery mode I do the following - options - backup & reset - enter recovery mode, tablet then proceeds to restart and recovery mode says the following

Android system recovery <3e>

Android sdk reversion: exdroid4.2.2_r1-a23-v2.0

Volume up/down to move highlight; enter button to select

- reboot system now

-apply update from ADB

-wipe data/factory reset

-wipe cache partition

-apply update from internal storage

-apply update from external storage

-apply update from cache

If there is anything else, I'd be happy to answer.

Also all of this existed before I rooted it, I used Shuarme? or something similar to root it, it did install some chinese software but after a factory reset, that's all gone and it's back to how it was when i first bought it. (in addition to the root of course). Shuarme also added Kinguser onto the device which still exists

Thanks.
[Android Q&A, Help & Troubleshooting] Cass1977:
Thats an Allwinner chip. This topic is for Rockchip based devices, the rk3026 to be precise.

The 3.4 kernel has been out for a while. My daughter runs it on her A20 with a custom rom.

You are running a standard recovery with no option to backup your data before a wipe. You should look for clockworkmod or TWRP (google it). They are the best recoveries and can backup ALL the different parts of your system (boot, kernel, etc).

You might want to search here for A23 or google things like 'Allwinner A23 cwm' or 'A23 custom rom'. If you head over to techknow.me they do a lot of stuff with Allwinners. Give them a try ;)

Hope this helps
[Android Q&A, Help & Troubleshooting] Mozelite:
I have looked on there regarding the A23 in specific but received nothing that actually helps, regarding google - I looked around quite a bit (that's how I found this thread)

I also tried to install clockwork mod and got errors, dont know why but it refused to install, it gets to recovery mode then says "no command" in the background with the options I listed before
[Android Q&A, Help & Troubleshooting] Emileh:
Ah I thought it was posted on page 2 or 3 of this topic?

Must be mistakin or its not usable.

My bad
[Android Q&A, Help & Troubleshooting] desarenezitic:
Ahh you mean the kernel source; that was posted by Chris back on page 3. To my knowledge no one has made a custom kernel for rk3026 devices, at least not from our 'team'.

Need CWM/backup for rk3028

Hello!

i've a kid tablet with rk3028. (1024x600, 1G/8G), "APAD R70DC", seems the same as http://www.aliexpress.com/wholesale?SearchText=kid+tablet+pc+rk3028+core&catId=&initiative_id=AS_20140331033004&isPremium=y Beneve R70DC

I've find for recovery and last found generic cwm from androtab.info.

I've tried TWRP also.

TWPR doesn't work, because no sense of tap-screen.

The CWM also doesn't work (generic v6.0.3.1): just by double press of vol+- steps the menu by 2 row (altrough the menu 'slection' is changes by step, so every menu selectable it is only cosmetic problem)

But when start any operation, the CWM said : cannot mount (everything):

Can't find misc

Can't mount /cache/recovery/command

Can't mount /cache/recovery/log

Can't mount /cache; /data; /sdcard; /external_sd; /sd-ext; /system

So just few function (e.g reboot device) working, none of needed (e.g. backup).

Sideload is works, but cannot install anything because mounting error.

I can get any debug info from it, if u say how can i got it, i'm newby at programming :)

Another question (but i'm afraid it is late): how can make a full backup of the device (from windows 8) like MTK droid tools full backup at MTK SOCs?

thanx!
[Android Q&A, Help & Troubleshooting] freibergisch:
There is an app called online nandroid backup in the store. With this app you can make twrp or cwm backup from whole system and you have not to boot in recovery, tha app makes it in running system.. :)

[Android Q&A, Help & Troubleshooting] desarenezitic:
With regards to your generic recoveries it could be you'll need to add your kernel to your recovery image. At first I couldn't mount anything in recovery because of this. Freaktabs may be your best bet in the TWRP thread.

Thanks, i'm now on freaktabs twrp thread, i hope someone can do it, i can't i'm afraid...
[Android Q&A, Help & Troubleshooting] Cass1977:
If youve got a kernel image I can add it to the TWRP.

If your having issues it means you have no default kernel on your system and thats NOT a good thing.

Id need more spec for your device to explain further but adding a kernel to the TWRP is not a problem IF you have your kernel
[Android Q&A, Help & Troubleshooting] poffsoft:
emmm, thanks, but how can i get the default kernel (from device?)?

And what specs need from it? I can get infos, if u say what (and witch apk/prg) is needed. :good:

i've installed nandroid backup tools,

[Android Q&A, Help & Troubleshooting] Cass1977:
If those images are from your device then they dont have kernels in anyway so the generic version should work on your device as it must have the kernel in a separate partition. Did you try it? If so what errors did you get?

[Android Q&A, Help & Troubleshooting] Cass1977:
to be fair i dont blame him. I have no idea why cwm is so hard to port to this device when there is one for the Cube U25GT (also a rk3026). I think well stick with TWRP for our roms. Although it can be slow it does have more features (like a command line which cwm really needed) and it actually works.

I haven seen any other recoveries yet but i did hear philz worked

I don't know about much rk SOCs but my device is rk3028.

The CWM working (that abdul_pt modded) in fuctions, just "cosmetic" problem that if i step up or down with vol keys, only the second step shows on screen (altough the selection "invisible" is moving, so i can access all the menus in blind).

The TWRP - after modded- not working for me, because the touch screen doesn't detect any tap. And i've no knowledge...

i then used vroot to root the device and switched su binarys

[Android Q&A, Help & Troubleshooting] Cass1977:
Im not so sure about that. The cube rk3026 CWM doesnt work for us so I dont think the KK rom will. Try it and see and report back. Would be good to know.

Ive had mixed reports about KK, some say its good some say its not. Im running 4.3 on my Galaxy S4 and dont think ill go to KK unless I need to.

Just because KK is the latest release doesnt mean its the best. It should be the worst as it will have had the least time in the 'real world' whereas JB is 'tried and tested'. Thats just my opinion. Ive seen a lot of things about KK not working properly on a lot of Samsung devices. To be honest, If it isnt working properly on a Samsung device it isnt going to work on an rk3026 :(

as far as 'crewrktablets' goes, they are the MAN when it comes to rockchip! NO question. Im running their multi-window ROM on my 3188. The guys are very good! BUT, Still not focusing on the 3026. Noone is :(

What we need to do is get all the people who want to work on the ROM together and set tasks for different levels. I have been using different kitchens to make the ROM I posted and it should work with most tabs. The issues with the kernel can be overcome by making a TWRP flashable rom but we need to make sure everyone is using it first. Most people want the 'one-click' option instead of installing a recovery and then flashing a ROM.

Onto the ROM. Ive made a few kernels ready for testing BUT they are for the 86v board (as thats the one my test device runs). I need to know what boards people are running so I can make a kernel for them. Ive attached a picture of my board so you can see what its like.

I was thinking of an flashable zip to install SU and busybox. Would this help? Im assuming you dont have a recovery so it will need to be an update.zip?

rkDroid is now using the rkdroid.com site. Its been transfered from the old site but a few bits may be missing :/ Let me know of any problems

Cass ;)
[Android Q&A, Help & Troubleshooting] webwalk®:
im not sure, my problem was that i had a secure system partition, according to this i can only temporary disable it, maybe it would have worked if i unsecured it, rooted the device and install adbd insecure.. i dont know how vroot got the job done but i guess somewhat the same way..

i currently dont have a custom recovery installed, still testing the stock rom and its performing very well for my needs.

i use paranoid android on my gs3 and its working great.. way snappier than any tw rom ive tried..

gs4 has official 4.4.2 update.. i would use it.. android got nice performance boost in this version

Recovery for Odys Ace?

There is a generic TWRP on the rkdroid.com site. It will work if you have a kernel partition (Which ALL 3026s ive seen do have). You could even test our new ROM? KitKat is a long way off for the 3026. Ive built it for the 3188 but not been able to install it and dont even run it on my S4. PacMan all the way ;)

We have an rkInfo tool that can pull your kernel partition (If you have one) and we can insert it into the TWRP if that helps. Its worth downloading the tool from rkdroid.com as it will give you more info on your device. Start a thread there if you get stuck, im sure we can get it sorted ;)
