how to customize a self-rom for T4242

hi, all,
I have downloaded a ROM of version 6.5 23506 ROM from xda, and a Iolite_RK tool too, but when i decompressed the rom, it only includes a sys folder and in this folder, no any other sub-folders except a .ROM is found. while some instructions say a .VM folder and a OEM folder should be included.
how to do it?
this depends on your base ROM.
you cannot get files sorted by packages if there are no dsm files in your ROM. almost all custom ROMs have no dsm files included.
try to decompress original official htc ROM and you will see how it works.
you can start htc update installer and it will create .nbh file in your temp folder. copy this file and play with it.
=)
ibmcom: Cooking custom ROM is not as easy as you think. There are plenty of tutorials here on xda forums. Read them and you will understand, how it works.
thks.
to serfer222:
where can i find the "htc update installer" files/program?
to torrentonly:
i have seen the dificulty. i have read some tutorials in Chinese forums, and i found lots of resoureces come from xda, so i also downloaded one wwe rom as the base kitchen.
how did you start from the first one? a official rom?
search the forum. it's in the next thread.

I mean any official installer works fine.
ibmcom: Official ROM is a must, because you need to have all base essential files, like drivers, etc. to match your device. Extract some official ROM using some visual kitchen (I am using one from ervius). After that, just try to cook it without any changes and flash your device (after HardSPL of course). If all will goes without problems, you can try to change some EXT packages and so on. The last step and most difficult (well not really, because developed tools make all much easier) is porting of XIP.
If you will succeed with all of this, you can play much more with you ROM, like deleting and editing some files from OEM and SYS. Good luck!
For your reference, here's the dumped file of Dopod_T4288 ChinaUnicom stock ROM:
Part00
Part01
Part02
Edit: Now I've made it into a flashable ROM, you can download it from this link:
RUU_signed_Iolite_Dopod_T4288_ChinaUnicom_Stock_ROM_1.13.706.2_Language_CHS_0804_NoRadio.7z
HTC TOUCH CRUISE 09 IOLITE T4242, 多普达T4288 中国联通定制原厂ROM, 基于HTC英文原厂ROM重建。
The ROM is Chinese language. Version is 1.13.706.2, original dated 29th of Apr. 2009.
It is made from the dumped raw files, base on HTC Asia WWE 1.11.707.1 Official ROM.
your given links are aimless.
i downloaded a english version. i am trying for serveral days, but no progress.
The aim is: You must have a Chinese stock ROM if you want to cook a Chinese ROM.

[Q] Files Required from Stock ROM in order to build AOSP ROM

There are many anecdotal notes here and there about ROM building, porting, etc. No where is there a list that outlines very simply (and device agnostic) what is required to 'pull' from a stock ROM in order to add it to the AOSP source code to build a fully working ROM image. I am looking for some help to define what this list might be.
I am creating this thread in the ViewPad 7 area because I am focused on this device at the moment, but this list does not have to be specific to this device, it just should be applicable to it.
Example:
Drivers
(Get everything in the /system/modules/lib folder and place it in AOSP/drivers/etc folder)
/system/modules/lib/* >> /AOSP/drivers/etc
Kernel:
Do a nandroid backup of boot.img and extract kernel from it via(...) then place that/those files into /AOSP/kernel
... These are all examples and do not represent real folders per-se.
Any help in assembling this list would be no double extremely beneficial to the entire android rom building community.
Thanks!

[Q] I have to branch my local copy of the AOSP repository?

Hi guys,
my first post here, i have a problem and it's about how to do things with the best possible approach.
I have downloaded an entire copy of a particular Android branch following the official guide and using the repo utility.
Now i have some modified files that i want to use to customize the build process, the problem is that i have already pasted this files over the ones in local repository and my repository is now unusable and repo gives only errors when i try to sync.
What is the best approach when i want to modify existing file in my local copy of an Android official branch? What is the best approach when i want to replace 1 or multiple files?
in other terms how do you organize your code and how you modify it.
is this forum dead?

Question about android .img rom modding

Hi!
I am new to modding, so forgive me if this is a noob question;
Is there an easy way to incorporate a small .zip update file into an existing Android rom .img file?
To be more precise:
I have created a custom rom for a Tanix tx3 mini android box using an existing rom and editing with the AMLogic CustomizationTool.
The clock on the device is not working and requires a small patch/update/fix, this patch is already available in a .zip file that has to be flashed using twrp after installing the rom.
Is there an easy way, just using the pc, to add this .zip patch into the .img file?
