[DEV] unofficial ClockworkMod Recovery 5 for Ingenic JZ4770/JZ4760 tablets

fun_ · Dec 16, 2011

this is a work-in-progress development project for porting ClockworkMod Recovery 5 to Ingenic JZ4770/JZ4760 tablets.

this is not perfect at all. and I'm very busy. progress will be very very slow. I may not be able to answer your question/request. if you have some idea for improvement, please do it freely.

there is no support from any makers/vendors. you must agree all risks by installing non-supported files, it may brick your tablet, and you may lose official support/warranty.

* YOU MUST READ CAREFULLY POST#1, #2, AND #3!
* DO NOT USE IF YOUR TABLET IS NOT LISTED BELOW. IT WILL BRICK YOUR TABLET!

* project page

* supported tablets

Velocity Micro Cruz T100 series (Android 2.2 updated model and Android 2.0 PT701i model)
Velocity Micro Cruz T301

* How to install ClockworkMod Recovery 5 (for ainol NOVO7 Basic/Paladin, Cruz T100 series, Cruz T301)
1. download recovery-signed.zip for your tablet (DO NOT USE FILES FOR OTHER TABLETS!)
2. (if you are using stock recovery)rename it to update.zip, then put it on root of SD card
3. install update.zip from recovery

on stock recovery, update.zip will be installed automatically. on ClockworkMod Recovery, you need to select menu item manually.

* How to install ClockworkMod Recovery 5 (for ronzi A3)
1. download recovery.zip for your tablet (DO NOT USE FILES FOR OTHER TABLETS!), then extract recovery.cpio.img from it
2. make backup of stock recovery

Code:

adb remount
adb shell mv /system/recovery.cpio.img /system/recovery.cpio.img.bak

3. copy recovery.cpio.img into your tablet, then flash it

Code:

adb shell inand_flash_image recovery recovery.cpio.img

* How to boot recovery
push & hold VOL+ while power on

* How to boot recovery (alternative)

Code:

adb reboot recovery

*How to control ClockworkMod Recovery 5
VOL-/HOME: down, VOL+: up, POWER/MENU: select, BACK: back

* Superuser, su, and busybox
it can be installed from ClockworkMod Recovery 5
- Superuser, su, and busybox for JZ4770 ICS
- Superuser, su, and busybox for JZ4760 Froyo

* random notes
- stock recovery
if you installed update.zip from stock recovery, stock recovery image should be renamed as /system/recovery.cpio.img.bak. (unless you didn't remove /system/recovery.cpio.img)
it can be flashed by "inand_flash_image" command. (use "flash_image" command for T100 series except PT701i model)

- mbr, xboot, boot, and recovery areas
backup/restore doesn't work for mbr, xboot, boot, and recovery areas

- time for reboot/poweroff (NOVO7 Basic)
I don't know why but reboot/poweroff take long time (as same as stock rom). you should wait 1 minute. if nothing is happened in 10 minutes, use reset hole

for now I'm preparing to push my changes to github. I'm very busy so it needs some time.

if you made some.zip file to do something for MIPS Android (e.g. superuser.apk with su binary for MIPS), please tell me. I'll add link to post#1.

if you have some idea for next work, please tell me too. (but, as I wrote, I may not be able to answer your request. sorry)

Thanks for your starting thread and project.

I bought a Advanced model but they send us a Basic Novo7.

All we know the incompatibilites using a cpu MIPS, that doesnt allow to run a lot of Android software that for default its compiled for ARM processors.

Im getting a bundle pack of apps running under our device.

thank you. I understand your condition.

but here is dev thread for clockworkmod for novo7 basic. if you want to talk about apps which support mips android and/or any general things about novo7b, I recommend you to make new thread for it.

I will do as you said

This is great news. If you are wanting to test any work with users on Velocity Cruz t301's which also run an ingenic processor (JZ4760) .

UPDATE: Tried running CWM for the hell of it on the t301 . Stuck at boot screen was able to get back to original recovery however. I'm guessing it might be due to the entry point into the kernel . Since the t301 is ancient Froyo. Would love to take a look at the source

vanduhl · Dec 17, 2011

Also here SHOULD be a working SU for MIPs. It work's on the cruz tablets

I couldn't read what you did exactly. if you flashed my image w/o modification, it must not work. as I wrote, DO NOT USE file for other tablet.

please explain what you did, and please explain detail about your tablet before any random work.

Attempted using the above stated method(understanding you said DO NOT US file on other tablet) I was curious to see as what kind of error would or may of come up. I'm interested in modifying this for the Velocity Cruz T301 tablet(running a JZ4760 processor) as that community of tablet users has been left under the dust. Now with the novo coming out it will further pile under the dust. I have not yet made any modifications to it, although I would very much like to.

kernel must not work because it's for NOVO7B. in general, kernel can't be shared among different products.

key assign, and partition layout may be different too. but currently I have no idea how to fix them because I don't have any detail about your tablet...

it seems JZ4760 is NOT MIPS32R2. then I need to recompile userland binaries.
anyway, technical detail is required to support other tablets.

it seems source code for xboot, android 2.2 and (part of?)kernel source for NOVO7B is released. I don't try to compile them yet so I may be wrong.
I'll check them later.

Is it possible that someday this recovery will be also ported for ainol novo7 Advanced ?

you should use search engine before post a question.

How did you get back to your stock recovery image on the T301? I think I borked mines on a T105 accidentally with ROM Manager. I accidentally pressed the screen too many times while 'exploring' and the delayed input caused ROM Manager to start flashing a recovery. Now I can't boot into recovery. I just see black nothing.

EDIT:

Disregard - My stock recovery boots. I was performing the boot into recovery procedure incorrectly. Also, because the recovery.cpio.img was in /system I assume it was flashed on each power cycle.

Apologize: I have read the complete topic and now understand that at present it is only for Novo.

Please dont use this thread to talk for another devices that arent be Novo7 Basic.

Asi cant start a new thread yet, here is my thread at spanish forum comunity with a full starter packs of mips app + games and a guide to be root.

I´ve got successfully get a compiled MIPS version of Titanium backup that works like a charm for our device Novo7 Device! Checkout at the link upside.

Regards. (I will open a new thread when i´ve got 50 messages...)
