T-R42 BRICKED

[JDfense]

I don't know. You can't choose anything in the recovery and an stock update.img should flash from internal store without trouble. Maybe your recovery does not support flashing from internal storage.
I have used this flashing routine with Rockship rk2818 the last time. :-)
Btw how do you get the update.img in the storage without PC.

Hello,
for recovery menu option:

update rkimage from external storage

i can put the update.img in the external SD card

and also
for recovery menu option:

apply update from external storage

i can put the update.zip in the external SD card
and choose it (the remote command works when i am in recovery mode, i can navigate on the menu)

The update.zip is seen by the device, it tries to open it but then it tells that it is not valid...

The update.zip that i put on the sd card is also automatically opened by the system without going to receovery menu...
infact after the boot, when the system starts (the few seconds it is not freezed), it asks if i would like to update it using the update.zip of the SD card

but i have not a valid update.zip... perhaps i have to build one...
i think i can try a generic update.zip for rk3188...

perhaps some owner of tr-42 can create it... i dont know with which application... perhaps the backup creates a zip file?
(i think it must not be an img file, it must be a zip of all system directories , meta-inf etc..
the classic zip file used to update smartphones...)

do you know how to create such zip file for T-R42?

No, I don't know for rockship devices. Be careful with generetic update.zip.
Has your stock recovery factory reset or anything like
format cache/dalvic cache?

Yes,
the options of the recovery menu (4.2.01) are:

- reboot system now
- apply update from external storage
- update rkimage from external storage
- apply update from cache
- wipe data/factory reset
- wipe cache partition

Have you tried a full wipe. This means execute wipe data/factory and cache. You will loose all user data, but maybe your ROM is then stable.

thanks, i already tried but with no success.... but

perhaps i found something that can help to build the update.zip by myself:
google `build your own update.zip` xda thread
and

http://androtab.info/clockworkmod/rockchip/rk3188/

download
generic cwm
if you try to install the generic cwm starting the update from recovery menu, the update starts,
but stops checking the device model...rk3066
perhaps its enought to modify the updater script where there is this check and rebuild the zip, signing it with the above tool

Hello,
finally i found the tool that signs correctly all the zips i create
and also the tool that helps to create the zip and the updater script, putting in it all the stuff i want (kernel.img, boot.img, and so on) to make a complete zip to be flashed via recovery menu from SD card, without the need of connection with pc, rkbatchtool, rkandroidtool and so on
It is an XDA thread:

http://forum.xda-developers.com/showthread.php?t=717437

My device find the zips created with these tools valid, so i can do any update i want
I already tried a simple updater scripts that only prints some informations on the screen with ui_print

Now i have only to learn the sintax of the updater script language, and to build the zip with all parts i need to recover my system...

Thanks
