[Workaround] XDA/Tapatalk App - JIT (Updated 06/22/10)

After reading many posts about not being able to the XDA App with JIT enabled… I decided to post this…
Here’s something I happened to “stumble” upon while playing around with ROMs with JIT-enabled. Hopefully this will help some others enjoy the XDA/Tapatalk App from their phones with JIT-enabled
I have done this on two (2) Cyanogen based ROMs (CELB2.4 and CE1.1). Both had JIT enabled by default.
In any case, I love being able to use the XDA App from my phone to feed my addiction However, I also enjoy having JIT and the goodness that comes along with it! So… I was playing with CELB2.4 and testing some battery life. After disabling JIT, I instantly started up XDA (as I was unable to use due to FC’s with JIT enabled). I logged in and browsed around. However, disabling JIT had no effect on my battery life, so I decided to re-enable. Later, without thinking, I started up XDA and browsed around some more. It didn’t hit me until a few minutes later that JIT was enabled and I was able to use XDA.
In any case, I loaded up a NAND of CE1.1 and did the same thing, with the same result. XDA app worked perfectly… and I’m still getting over 5.3 mflops
I think there are other apps that have issues with JIT, however, I personally don’t use them. Hope this helps others! Would love to know what ROMs this “trick” works with, and/or which it doesn’t.
------------------------------------------------------------------------------------
I highly recommend doing a NAND backup before doing anything. It's just good practice!
There are a few methods to enable/disable JIT... here's what I did (using a Windows machine):
Disable JIT via adb:
adb remount
abd pull /system/build.prop build.prop
Open build.prop in Notepad/Wordpad or favorite text editor (file will be in the working directory)
find the line:
dalvik.vm.execution-mode=int:jit
replace with:
dalvik.vm.execution-mode=int:fast
SAVE
adb push build.prop /system/
Reboot Phone
------------------------------------------------------------------------------------
After disabling JIT, reboot, open up XDA App, login and browse around (as a side note, I created a favorite to the Eris Forums). Then, close out of XDA App, and then re-enable JIT and reboot.
------------------------------------------------------------------------------------
Enable JIT via adb:
adb remount
abd pull /system/build.prop build.prop
Open build.prop in Notepad/Wordpad or favorite text editor (file will be in working directory)
find the line:
dalvik.vm.execution-mode=int:fast
replace with:
dalvik.vm.execution-mode=int:jit
SAVE
adb push build.prop /system/
Reboot Phone
------------------------------------------------------------------------------------
Alternatively you can also use a program like Root Explorer to find the build.prop file in the /system/ folder and edit/save/reboot.
Again, would love to know the results this has for others!
------------------------------------------------------------------------------------
Thanks to a post from thenestor, it's been discovered that version 0.9 of the XDA/Tapatalk app works just fine with JIT (regardless if an AOSP or other ROM). I'm currently using version 0.9 on xtrROM and it works great. I have attached the zip with the 0.9 apk. It has a "funky" name... and I didn't rename... I simply used Astro to install the apk. works great!
MODS: if for any reason I am NOT allowed to have version 0.9 posted, please let me know, and I will take the attachment down ASAP.

I vote for a toggle app/widget

Root Explorer
It works! Used root explorer...nor really that hard to do. Thanks for sharing your discovery.

didnt work with Aloysius v12. Oh well.

I was using Eris Lightening Bolt 2.5.

When I loaded the app the first time on my ELB install, it crashed. However, I reloaded it straight away and it worked. I did not disable JIT or do anything else to make it work, just restarted the app. It hasn't crashed since. I have, however, had it sit and spin on "Processing".

Didn't work on latest ErisLightningBolt 1.4.
1. XDA didn't work w/stock config.
2. Changed int:jit to int:fast.
3. Rebooted.
4. XDA worked! Signed in, created some favorites.
5. Changed int:fast back to int:jit.
6. Rebooted.
7. XDA FCs.

I can confirm that it works.

Re: [Workaround] XDA/Tapatalk App - JIT
@zach.xtr
I found out that all I had to do was add the string to build.prop
I followed a POST on "Jcase's Universal JIT Update"
I added these two strings at the bottom of build.prop
dalvik.vm.execution-mode=int:fast
dalvik.vm.heapsize=38m
That fixed the issue with xda tapatalk closing randomly. I still have yet to re-enable "jit" to see if the workaround works.
Thank you for the help and replies.

If you don't want to disable JIT, or if you're on a ROM where disabling and re-enabling doesn't work, just downgrade to "xda-developers app v0.9" (not sure which version of the real Tapatalk) and it works with JIT.

is 0.9 a google apk search?
have a link?

sweet! found it! much like thenestor, i had to find it using some "crafty" methods! lacks some of the "favorites" w/sub-forums... but works VERY nicely with JIT.
thanks for the tip thenestor... good stuff!
if i'm allowed to post 0.9 version, i will gladly do so! (nothing wrong with it, i hope?).

270 rotation

I'm a noob when it comes to coding and I need help. Not sure where this goes forum wise but can anyone help me remove the 270 rotation and just have the normal 180? Move me if this is general, I just can't stand the 270 anymore. I'm running baked snack 1.4 with acs 1.6 kernel and the frost remix theme. Help!
Sent from my SPH-D700 using XDA App

I would instead like to use this on a stock ROM, so any insight on this would be equally helpful for the opposite

In your build.prop file, change this line...
windowsmgr.support_rotation_270=true
to
windowsmgr.support_rotation_270=false

And how would we go about adding it? I mean, I know it's in the framework, so it means decompiling, right?

Its not in the framework, its just part of the build.prop file, thats it (sounds wayyy too simple, I know).
So basically just do the opposite, change false to true. Normally I'd use something like "Root Explorer" and edit the build.prop file in the text edit mode.

any froyo fix
Has anyone come up with a froyo fix for the 270° rotation? It used to be an easy fix, but with the froyo I can't find it in the build prop. Any ideas?

easiest way I know...
dl terminal from the market
open up and type "su" and then hit the enter button
then type "180forme.sh" and then hit the enter button
then reboot
Sent through the Matrix

Cool thanks for the lead.
Well no luck with the 180forme.sh in terminal
Any other thoughts?

Did you change directory to the one with the 180 degree script command?
Epic Experience 1.2.0.8/Phoenix 1.49s/Elegant Steel .02

make sure its "terminal emulator" that you downloaded. "su" allows superuser to let terminal make changes. "180forme.sh" should work. its what hero suggested when asked how to go back to 180 rotation. and make sure that you reboot your phone after. it worked perfectly for me. maybe try reflashing and then using terminal.

[HOW-TO] Remove the FPS limit on stock-ROMs

Huawei decided to put a FPS limit on its stock-ROMs, and this limit makes a stock-rom jerky and unsuitable for gaming.
I have looked for a script that was able to remove this FPS limit but the only one i found was not working correctly.
Then i found a really useful script that disables the VSYNC (enabled by default in the kernel).
I have tested this script on my u8800pro (stock 2.3.5 + root + CWM recovery + kernel .35 by genokolar) and it works really well. The rom now is really smoot, like CM7, and fast.
I haven't noticed any lag.
This is how to remove the FPS limit:
download this file http://sourceforge.net/projects/matteof93.u/files/69uncapfps/download
put it in your sdcard
download the app "script manager" from the market
open the script with script manager (remember to select run as root and run at boot)
after running the script for the 1st time, reboot the phone
To check if the script works, use an app like Neocore (i get 55FPS).
This script should work with both u8800 and u8800pro. I don't know if it works with the stock kernel.

First you say it doesn't remove the limit but disables the vsync, then later you say how to remove the FPS limit and the topic also states that.
What's it gonna be?
Ok, the script simply edits a system file to disable the vsync...
Code:
#!/system/bin/sh
#zdzihu: uncap fps
mount -t debugfs debugfs /sys/kernel/debug
echo '0' > /sys/kernel/debug/msm_fb/0/vsync_enable
umount /sys/kernel/debug
Nice move, but it's not cool to just tell people to run some script from "megaupload" or whatever...

Stockwells porting script question.

As some of you know, stockwell has a miui porting script. I just began to wonder, can it be modified to port other roms from desire z? If someone could alter it a bit try to port one of desire z roms. I have very little knowledge on linux, but someone with more could do it.

Ret4rt and darksage have this script. They can answer to this question.

U could try and just read the script from the github.. U could see the script will automatically add and replace some files and delete unnecessary file from Desire-Z ROM.. U can do it using windows AFAIK... Try using this tutorial

Stockwell make it easy for us actually, if u check that github, there's an "overlay" folder.. Inside is all the file needed to add into the desire-z rom,
including the updater script (/ overlay / META-INF / com / google / android )..

TWICS

Captivate currently had TWICS. Its base code from cm9 with TW launcher and Samsung gs3 add on with devil kernel. Running this o my cappy. Super fast and stable. Just an outstanding rom.
Can someone port this to vibrant please!
What are you looking at shortbus......

*NOT SURE/CONFIRMED
But since it is in the line of the original galaxy s, I think you can just flash it, and then change modem/kernel/key layout, which is done by a script (forgot what its called in our development section)
ok, i found it
http://forum.xda-developers.com/showthread.php?t=1623840
Using that, you SHOULD be able to flash any Galaxy S ROM (except the 4G)
If it doesn't work, nothing will go wrong, most likely you will
1) boot loop
2) key layout will be mixed up(easy fix)
3) no connection (change modem/kernel)
*you said this was TWICS, make sure it is ICS and not just themed to look like TWICS.
Link to rom please?

OK so I tried it from the captivate before I saw this post. Installed rom and before it gave install complete it auto rebooted. The rom was on my phone but up was down left was right ie screen was in landscape then when I turn it sideways it would go to normal view. I rebooted to recovery and ran patch then reboot and wouldn't get past vibrant screen. I will try again with i9000 rom and let you know the results.

Try to flash the Subzero kernel from here: (use build 80 not 128) http://rootzwiki.com/topic/22833-kernelics15-june-subzero-v14-build-128-brain-dead-and-loving-it/
If you already tried it from Subzero kernel; try the Glitch kernel, its on these dev sections.
Flash either of those to the ROM you currently have, and then try to flash it.
EDIT----------------
"if you are getting status 7 or getprop error then a little work from your side is needed
extract the rom to a folder then go to /extracted folder/META - INF/com/Google/Android from there open updater-script and remove all getprop lines
come back to META - INF folder and delete all three files
zip the file and flash it in recovery
NOTE:- to edit updater script use jota text editor(android), notepad (windows)"
It's in the patch's thread.
Do that.

I followed the thread exactly used jota changed everything and tried again. It just aborts install. I haven't given up. Gonna try again tomorrow. It beat me tonight but not for good! Thanks for everything x.

firstly I want to tell you that because of not having a vibrant to test the patch is in beta
what you can do is open updater script with jota text editor and remove all those getprop lines from the script and as a security step what you can do is press menu button then tap on file and tap on line break then select (lf for android/Linux) save the file go to meta-inf folder and remove all those cert files
zip the package again and flash no need to sign it again for further help you can ask me also in the patch thread

Thanks for input. I first tried it using a captivate port and it would install then I would run patch and it wouldn't boot past vibrant screen. Then I got the original galaxy s rom that the cappy rom was ported from. It gave the error so I proceeded to change the file as per op instructions. It would abort install with but no error status. I did it twice to make sure. If I changed all the get prop from i9000 to t959 would it work?

you should not replace them instead just remove them
after flashing if it gives error then reboot device and with any root explorer app go to /cache/recovery and upload both the files I will see what the error is and then I can troubleshoot better

So guys I'm the twics porter to the cappy twics will soon be called remics I've been a part of a team that took over twics and I will soon be releasing to captivate

Just go to that file, copy it and paste it into your SD or something, and then upload it from there.

Because I have flashed a new rom and kernel the recovery log doesn't have the abort/error info...
