I am trying to unpack the recovery image of a Yuhua Touchstone running Android 2.1 (marketed as an I-Mobile i858). I have tried every method mentioned on this forum and wiki and elsewhere on the internet (extensive Googling) and the standard perl scripts, such "unpack-bootimg.pl" and "split_bootimg.pl" are not working. They say that a ramdisk is not found or Android Magic is not found, respectively, and then quit. I need help deciphering the recovery image so I can replace it with a custom recovery program.
To give more insight, when the phone is updated, the recovery.img is written raw to the partition.
Ex. write_raw_image PACKAGE:recovery.img RECOVERY:
Here is the latest recovery.img for this device. Thanks in advance for any suggestions, advice and assistance.
recovery.img from I-Mobile i858 (Yuhua Touchstone) Android 2.1 rom version 1632

mid w9 use rk2818 chip
i use rk2808 mod tools unpack the system.img but not
pls help me how to unpack/pack to the w9 system.img
thanks master
any one help me
You got any luck with that? I have been trying everything I could think of without success.
http://twitter.com/naobsd has expressed interest in helping.
He needs a system dump
RK2818 can be rooted with UniversalAndRoot
You then need to run a Terminal Emulator application to dump the contents of /system into a tar and upload it
If you can dump the contents of other useful partitions, that might be good as well.
sorry for my inaccurate explaination.
I don't want dump image itself.
I already know
1. system.img in update.img is encrypted (other files are not encrypted, same as RK2808)
2. RKAndroidBatchUpgrade.exe for RK2818 decrypt system.img, then flash into device
3. decrypted system.img(cramfs) can be get by dumping system partition on live device
4. dumped decrypted system.img can be unpacked by fsck.cramfs
then, I want know following procedure can be done:
5. pack update.img with dumped decrypted system.img from device
6. flash update.img(5.) by RKAndroidBatchUpgrade.exe for RK2818
it should be easy to try, but I don't have any RK2818 device. I'll get ONN-N2 but no official firmware is released yet. so I can't make complete update.img for ONN-N2. (no RK28xxLoader(L).bin)

I know old flash tool for RK2808 can flash single partition. I think it should work on RK2818 because new flash tool for RK2818 can be used for my RK2808 device (iRobot)
but, anyway, I don't have RK2818. I can't test anything on real RK2818 device.

Wopad?
I'm not sure if I have the same device as in this thread, but I'm familiar with adb and rooting. I've tried universal Androot on my device and it doesn't give me root. Z4root does but only temporary. I would love to help with whatever you guys need, just need a couple commands and will send files.
Oh it's a wopad rk2818 capacitive no trackball 2.1 model 7001
i can give any other info if needed. Hopefully we can get some kind of development going on this tab. It's a good little device, Rom is not so good though.
For reference, W9 ROM:

My tablet is based on the rockchip 2818 ref. design, the pure odm device as it were, model is the yifang m7.
The issue i stumbled upon is that the little ****er is still encrypted on the blocklevel device. (mtdblock4 for /system)
Hello,
I apologize for the wide broadcast as I don't have the priviliage of directing my Q to Android-Samsung-S3-Developer's forum.
Background:
Using ASOP 4.1.1_r4 I have been able to extend the Wifi services, framework, wpa-supplicant, and WifiManager API and successfully (developing on a Ubuntu-12.04-LTS/64bit) update the firmware of a GalaxyNexus phone and use the new SDK with my diagnostics application.
Problem:
Due to project erquiremnets I need to repeat the process on Samsung S3, however
after successfully building the (GT-I9300, update 6) Samsung-Open-Source Kernel, also building the ASOP 4.1.1_r4 (after applying the Samung-Framework-delta), and using Android-Kitchen
to create and MD5 the tar ball, and after updating the S3 (via Odin 3.7) the handset hangs. Fortunately I can recover it with the stock-firmware available.
Please note that I only replace system.img (user-data, cache, modem.bin are from stock firmware). No PIT file is used in ODIN3.7, and "Re-Partition" is not enabled.
I would appreciate any assistance in the following:
a) I can unpack system.img built from ASOP and packed by mkyaffs2image tool (via unyaffs2 with chunck-size of 2048 and spare-size of 64) however I can not do so with the stock-firmware system.img file.
My own system.img is around 200M, however the stock system.img is more that 1G. Any ideas? Thank you.
b) Can you point me to a how-to guide on building S3 image from ASOP source, packaging it via Android-Kitchen and uploading it via ODIN?
Thank you very much and I apologize for the lenght of my posting.
Regards,

Hello all,
I really need, for a commercial project, to flash a great number (>100) of Galaxy Camera 2 (EK-GC200() device, all with the same firmware, rooted and modified as I need.
I have to flash boot.img (modified by me) and system.img (rooted).
I have now to root the camera, then start the system, enable developer options, enable adb debug and at the end flash a new boot.img, and the system.img itself (adb shell, dd ...).
This is time consuming, and error prone.
I'm sure the boot.img & system.img are correct, cause I can flash them without error (and they work fine) with dd from the internal emulated sdcard.
I can see two viable alternatives:
1. A custom recovery, from where I could make a nandroid backup, which I can use later on to update all the rest of the cameras.
But:
I tried to port the EK-GC100 cwm recovery, I've been able to boot it up, but the touchscreen is unusable and I got a lot of error coming from the file system.
Please help me! Any suggestion, half project, everything is really appreciated!
2. To create an Odin package, using the .img files I can optain with dd from a ready camera.
But:
I tried all I can do to build a Odin package, but every time I got an error (Odin Fail) when I try to flash system.img.
I tried to build a package containing recovery.img + boot.img, and that works.
I tried to build a package containing only system.img, and it doesn't work, every time I got a Fail from Odin.
I tried manual compression (tar + md5sum on Linux), and automated scripts you can find on XDA, both under Linux and Windows.
Why is system.img impossible to flash?
What am I missing?
Thank you in advance.
Ciao,
Giovanni
Hi all.
I'm not able to create an image file for LiveSuit to flash an A10 Allwinner based tablet.
have been following tons of tutorials but Linux to me is something too hard
http://www.allmost.org/2012/11/how-to-allwinner-image-building-or.html
I already have dumped the firmware images with Uberizer software but I need to create this IMG file for LiveSuit, ,PhoenixSuit or PhoenixCard programs
it's very simple to flash Rockchip based tablets with RK Android Tool but this process doesn't work on Allwinner based tablets unfortunately.
the question is: could someone here make a LiveSuit image for me ?
I just have to upload the dumped files: boot, bootloader, data, recovery, system...
thanks :good:
Please don't create duplicate threads,

Thanks! And thread closed.
Is there any program that can edit / modify recoveries?
I have tried to make cwm and twrp for a Panasonic KX-PRX150 by unpacking replacing files and repacking but nothing the phone's screen remains black when booting to recovery mode.
I have also tried to flash the stock recovery and it is not in recovery.img format but in recovery-from-boot.p and a install-recovery.sh flashing it on recovery mode.
Try this guide. I've never tested it.

Thank you. But I was thinking about Editing my stock recovery.
I'm fond of my own ImgUtil.exe (in the sig) which can modify boot images without taking them all apart and putting them back.
I usually start with stock recovery and replace adbd with a rooted adbd, add a service for it in init.rc (if there is none).
This should all work fine unless you have issues with AVB.
