PRS-T1 Your Rooted PRS-T1 (Screen shots and observations)

[vishcompany]

Thank you Morkl for the instructions.

I admit, I was a bit lazy, so I just downloaded your v2.zip

First I was a bit in a rush, so I copied the EbookHome.apk to extsp and ran an installation, which did not complete successfully.
At a closer look I realized, that it is to be handled like a flash package, so I ran the flash_reader.bat. After this, the Sony stock homescreen was gone. Pressing the home button let me choose between ADW Launcher, the alternative homescreen and something else, but not the stock home.

No problem I thought, my fault, should not have run the apk installer. Did a complete recover via sd-card, removed some debris from the former root, which was still there, rooted once more. All fine.

Running the v2 hack once more resulted in losing the homescreen again. Now pressing the home button brings me directly to ADW.

Am I missing something, or is there a bug?

(sd-recovery running again right now)

Not sure what's wrong - the flash package has worked fine for me. Trying to install the apk manually shouldn't do any harm, the system will simply refuse because it is a "system app".

I'm gonna do a sd-recovery and try to install again to see if i can reproduce.

If you have script.log from your internal storage at hand, what does it say? This is what it looks like for me after a successful install:

Starting ./update.sh

Edit:
Did you have "Enable apps from other sources than Market" or whatever it's called enabled?
Have you run the adb-enabler/was USB debugging enabled?

[vishcompany]

here is my script.log (I guess from the second run):

What comes to my mind, is, that I still had/have the books.db hack (showing recently read instead of recently added). No idea, if this can cause trouble.

[Morkl]

That looks about right. The books.db hack shouldn't break things.

Was "Enable apps from other sources" enabled?
Have you run the adb-enabler and/or was USB debugging enabled?

[vishcompany]

at the first run:

enable apps from other sources was enabled.
adb is not installed / active.
USB debugging was enabled.

at the second run, I don't know. I had wiped the root and not changed anything yet in the settings.

I had Link2SD installed (see wiki).

When flashing and reflashing back and forth now, I noticed:
- the second reboot was triggered, but then the device got sort of stuck
- the ext SD card was still resident (2nd partition!), the LED next to the SD card was flashing very busily in some kind of repetetive pattern.

So I removed the SD, restored, rooted, took a deep breath and ran your installer once more (v1 this time).
Went just fine!
So I did the v2 as well, also no problem.

I will fix the 2nd partition in my Linux box tomorrow before re-inserting the card.

Thus: thanks for the hack, works like a treat!

[Morkl]

Okay, great! And I was just about to report that I was unable to reproduce your problem - now i know why!

BTW: You mentioned you had the books.db hack still; if you want to remove it without having to rebuild the database, you can open books.db in SQLiteSpy and navigate to:
main->Tables->books->Triggers->Right click 'recently_added_trigger'->Drop trigger

[vishcompany]

Thanks for the hint about dropping triggers.

It's all in the wiki now.

I'm not sure yet how to handle the hack while Link2SD is installed.

Could anybody try and confirm, if it works to just remove the card while flashing, or will this cause trouble because of linked apps not being present?

There are a bunch of extra steps that need to be done to the APK in order to modify it and get it to work on the reader afterwards:

Tools needed: apktool, smali and dexopt-wrapper.

Procedure:
1: Disassemble EbookHome.odex using baksmali (baksmali -d frameworkdir -a 8 -x EbookHome.odex)
2: Reassemble into classes.dex using smali (smali -a 8 out -o classes.dex)
3: Put classes.dex into EbookHome.apk
4: Unpack EbookHome.apk with apktool (apktool d EbookHome.apk)
5: Make any changes in the newly created EbookHome directory
6: Repack with apktool, new apk ends up in EbookHome/dist directory (apktool d EbookHome)
7: Put the new apk on the sd card of the device
8: Run dexopt-wrapper on the device to get a new EbookHome.odex (in a shell on the device: dexopt-wrapper EbookHome.apk EbookHome.odex)
9: Remove classes.dex from the apk
10: Sign the apk with a suitable certificate
11: Run zipalign on the apk
12: Install on the reader

Or, if you just want the string "Recently Added" replaced with "Recently Read", you can use my modified files: http://morkl.se/reader/recentlyread.zip

Great post, thanks for posting the steps, will very helpful for developers new to Android wanting to modify any of the built-in Sony APKs!!

Also a nice HomeScreen for the T1:

This is very interesting. Does it also works for books which are not opened by the default reader? I no don't use the stock homescreen because the last opened book is only updated when it is opened with the default reader. I rather use FBreader...

A nice project indeed. Personally, however, i personally prefer the layout and look of the original homescreen.

I haven't changed the way the "last read time" is updated, but I'm putting that on my TODO list

Anyhows, I've made a new version. Posted it in its own thread though; no need to keep cluttering this thread up with technical bits

Getting back to topic; i have attached a screenshot of my current home screen, with the Store and Periodicals button replaced!

Hi friends,
I installed hacked version for my eBook as it was instructed. But once I detected that USB connection is not working, there was no link to connect PC to eBook. Than I made a big mistake and tried to delete some system files( I think the hacked ones) from inside of my eBook by root explorer. After that I can not shut down my eBook not connect to my PC. When pushing the power button it just goes to sleep mode. Resetting didn't help. Anyone has an idea how to solve the problem? Is it possible to run my eBook from external SD card?
Thanks from now.
