See my other post #27. Its got the stock recovery and the tools to flash it. should get you back to normal. Does your cwm do this weird thing where the blue bar only moves 2 places at a time? Mine does. I can click down once and i can still access the function but the indicator bar only moves 2 places at a time. Very strange, what have I created, lol.
[Android Q&A, Help & Troubleshooting] desarenezitic:
Oh right, that will be a Monday job I think then. Yes I got that two options thing, didn't know that you could select the option though.

If I can't flash the stock recovery I'll await you custom version.

Much as I hate to double post I wanted this to show as a new post. A couple of developments today, firstly the proc partitions are here proc.txt.

More exciting (possibly) is that I finally got a Firmware link from GoTab, currently downloading but don't think I can get it on DropBox before I leave so direct link is here; hope this helps.

Let me know what you need on Xposed mods and I can provide the info, I have Expanded desktop, 'Phablet' mode (nav bar bottom, status bar at the top), battery percentage etc etc

Pretty much the same as mine except that kernel, system and userdata are slightly bigger on mine. I unpacked the firmware in the link and it all looks identical to mine so at least were working with the same setup. Ive been trying a few tweaks to other cwm packages and none work :( still this dam 'misc' partition not being seen.

I tried a build of cwm using the cm sources and it just built the stock recovery :( grrrr. This will not beat me! Im sure its something very simple that im missing, just cant put my finger on it.

Dont worry, ill keep on it and see what i can come up with. Any ideas you have feel free to share ;)
[Android Q&A, Help & Troubleshooting] desarenezitic:
OK so that's good at least. I've registered on Freaktab to see if the guy making the TWRP builds can help because it's the same problem.

He has the firmware link also. Meanwhile I'm doing nothing, so if you tell me what you need regarding mods I can get the info together.

[Android Q&A, Help & Troubleshooting] Cass1977:
Congrats on being able to post links ;)

What I needed was recovery.fstab from the recovery partition but im expecting it to be the same as the ones ive seen so far. It looks like the file system spec for me and desarenezitic are the same and im betting yours is too. To confirm id like to see the output of /proc/partitions and /proc/mtd.

Ive been working with this and from what I see there are a couple of things that could cause this as its shown up on other devices but noone has an answer for rockchip devices (maybe because this is the only one that has this issue) :

CWM cant gain proper root access to the file system

Locked bootloader

error in misc partition (misc actually holds the reboot options for recovery, it's a bunch of zeros except for "boot-recovery" and "recovery.wipe_all", once it reboots and recovery is done, misc is cleared. )

I think the error could be in misc so im going to compare the 3026 one with my working 3188 one. could be as simple a a zero out of place or I could be totally wrong, lol. Looks like its a hex editor to edit this image as ive not seen any unpack methods and it probably cant be unpacked in the traditional sense.

Has anyone got any experience with TWRP? Could be helpful info

;)
[Android Q&A, Help & Troubleshooting] Cass1977:
post the freaktab link please
[Android Q&A, Help & Troubleshooting] Cass1977:
Just out of interest, how did you flash it? rktool or flash_image or other?

Just tested it and it boots but the touch doesnt work and nor do the hardware buttons. im thinking an easy fix once i unpack the image (I hope). ill post my results
[Android Q&A, Help & Troubleshooting] Cass1977:
ok, cant unpack it, says there is a space after the name (which there isnt). Odd that I can flash it and it boots but cant unpack it? Just need to modify the drivers for the touch screen. Was this built from your kernel or a fakekernel build? Might explain it.

Post all the info you have on it please and I can see whats going on and work out porting it ;)

Now you have a working recovery, are you interested in working on a custom rockchip rom with me? Any help (tester, advice, ideas, coding, etc) will be useful! If this can be ported to other rk3026s (which im sure it can) then we can do a cross chip (IE 3026/3066/3188) mod (maybe using Aroma).
[Android Q&A, Help & Troubleshooting] desarenezitic:
Right quite a few points to get through here; first things first the FreakTab link as requested Unofficial-TWRP-2-7-0-0-for-Rockchip.

I flashed it through terminal as I wasn't on PC last night (so flash_image recovery /sdcard/recovery.img). I gave the guy on FreakTab the Firmware link I gave you and he made it from whatever he got from that. I assume it is specific to my tab as he named it as such.

The TWRP is slow to respond when pressing a button but it does work, I've made a backup and flashed a GAPPS package today to try and get play store back (no joy on that it appeared to only flash two or three apps plus the Google setup). You mentioned hardware buttons, do you mean volume and power?

I'm am definitely up for helping on a Custom ROM in any way I can, it would be my first and I have no specific coding skills but am willing to 'get my hands dirty' so to speak. Can do testing and ideas for sure, will try and help with other stuff and I'll probably try and modify and maintain a GAPPS package also.

Think that covers everything!

WORKING TWRP FOR ALL rk3026 DEVICES

*******FINAL SOLUTION*************

This should work with ALL rk3026 models. This is a rebuild version of TWRP with the kernel removed. It will boot up with the kernel in the kernel partition of the device so should work on all models :) :)

TWRP for rk3026

Can you guys test it and let me know? It is slow but it does work so untill we get cwm working (Im still working on that) this is the best we have, but at least it works
[Android Q&A, Help & Troubleshooting] desarenezitic:
Downloading now; will test later or tonight (at work currently :P) Can what you know on doing this TWRP be 'transferred' to get CWM up and running?

Oh and the TWRP I posted was made with the kernel from my Firmware.

EDIT: Can't get it to boot into recovery; reverted to my previous recovery.
[Android Q&A, Help & Troubleshooting] AbduL_PT:
I think i will watch this thread,

Why don't unpack a working CWM and repack it why your ko modules ?

That will also work.

You could just have asked.
[Android Q&A, Help & Troubleshooting] desarenezitic:
Good to see you, any input welcome. I'm happy with the TWRP you made for me, it's just a touch slow but cass wants to make a CWM also, hopefully you're input will help him. Personally I thought you were solely on TWRP.

[Android Q&A, Help & Troubleshooting] Cass1977:
You need to do more than just add some kernel modules. In fact, i dont think modules even come into it. Ive been running CWM for the rk3188/3066/2926 on it and all work (or dont) the same. It is coming back with problems mounting misc. Ive tried everything I can think of but still the same.

I was having a dumb moment earlier and uploaded the wrong file, lol. That was the TWRP with my kernel. Sorry.

This is the proper link to the (tested ok on my tab) generic TWRP (no kernel). It works quite fast for me but you do have to remember to double tab the options.

Hey guys,

I'm in the same boat as you just a different device... I have a Visual Land Prestige Pro 7D tablet with a RK3066 and I'm currently working on trying to build a cwm for it.

I wrote a tutorial on rooting it and the method should work just fine on your RK devices as well and doesn't contain any malware or spyware and doesn't install a foreign SuperUser app on the device. You can check it out here -

Yep that is the cwm that I'm trying to work with, I just don't know how to find out if I have a valid kernel in the kernel partition for the generic version. I downloaded some of the RK tools, the generic cwm and did a romdump and extracted the boot and recovery.img, but that is a far as I've got so far.
[Android Q&A, Help & Troubleshooting] Cass1977:
Simple answer, is your rom stock, unmodified from the factory? If so then you will have a stock rom. If your unsure either 'cat /proc/partitions' or 'cat /proc/mtd'

If you see a kernel partition there then just 'dd if=/dev/block/mtd/mtdblockxx of=/sdcard/recovery.img' Where xx is the partition of your recovery.

These are all adb commands. If you dont know adb then DONT try it. I have a stock recovery for the rk3066, but, to be honest, ive got the generic rk30xxcwm recovery working on an rk3066 and an rk3188 so Im sure it will work for you.

Here is a LINK to the one I use. (Shameless plug to our new site ;) ) If your interested in making a custom rom then get involved with rkDroid. We are trying to make a device-wide rom for all rockchip devices.

;)
[Android Q&A, Help & Troubleshooting] Cass1977:
To be honest, I just got the recovery working and then did nothing else on the rk3026. Im sure my daughter will kill me if i keep messing with it ;)

I guess root shouldnt be too hard as they have adb root to begin (If not full root), so the recovery should be the last step (not sure if it roots it with the TWRP recovery, not tested it).

Ive updated the thread for our rom and im thinking system.img is the thing we need to start with. See here for my ideas.

[MENTION=5556677]Cass1977[/MENTION]

Thank you.... It is a stock ROM. I've only had the tablet for a little over a week. There is hardly any information out there for my specific device and I'm just now starting to become familiar with the rock chip as it quite a different beast than what I'm use to in my experience with my android devices. I'm getting ready to try and install the recovery. I'm having a problem getting in to the stock recovery as I can't figure out the key combo to get past the android guy on his side with an exclamation point to the actual recovery menu and I don't know if once I flash the new cwm recovery if I'll still have the same problem. I'm pretty familiar with adb so I'll give those commands a try. Will those adb commands work for installing the recovery without using the flash_image file?

I'll definitely check out rkdroid and would love to get involved. That's so crazy that there can be one ROM for all rk devices.... It would be nice to have a custom ROM.
[Android Q&A, Help & Troubleshooting] xdrc45:

[Android Q&A, Help & Troubleshooting] freibergisch:
Is there a working cwm for the rk3026 devices now? I made a cwm build via cwm builder but without success.. But this could also be related to the flash method I used.. I installed the new recovery.img with nandroid manager (app from play store.. flashes with flas_image binary)

When I rebooted to recovery, the old one started with the text like no command ...

Did you get a working cwm for this devices?
