[ROM][Stock 3.2]][CWM][XXKJ4][rooted + busybox] P7310 WiFi only

---

Here is a stock 3.2 ROM for P7310 (WiFi) that I built from a system.img and boot.img from P7310XXKJ4(thanks poolguy!). This is good for testing, ROM bases, or for folks that like stock and don't want to flash XXKJ4 with ODIN.

• HC 3.2 P7310 XXKJ4
• CWM Recovery flashable (system and stock boot.img)
• Deodexed
• Zipaligned
• Rooted + busybox
• Added Email.apk from 10.1 ROM
• Works great with my v2 kernel for HC 3.2

As-is...I will provide no support for this stock ROM.

Thank you! Doing a Nandroid backup now and checking this bad boy out!

Edit: Its running great so far. Installed the kernel and OCed to 1.4 (1.5 would shut down half way through the benchmark). 5815 in Antutu. Thanks!

3.2 Not as good as 3.1

Having tried both your modified 3.2 ROM for my GT-P7310
and an unmodified 3.2 version,
I'm VERY disappointed in the results.

In both cases, EVERYTHING on my 8.9 WiFi Tab runs slower.
Superuser problems arose when I tried to run Root Explorer or any
other apps that require SU permission. Updating to SU 3.07
didn't even fix the problems.

Used CWM restore and went back to stock 3.1 (P7310ZSKH4)
with your motley_v1i.zip and everything running fast & smooth again.
I have CPU Max at 1504MHz and Min 216 MHz with Scaling on conservative.

Glenn, after running on this for a couple days I have to agree with you about performance on Samsung's 3.2, although I didn't have any of the SU issues you are reporting. I don't think Samsung has released 3.2 officially for the 8.9, perhaps due to this reason and all the issues they had when rolling out 3.2 for the 10.1. Even though we can get the early update from Samsung using apps like the Check Fus Downloader (where XXKJ4 originated from), I just don't think it is ready for prime time yet. If you look at the Overcome thread, users are expressing the same frustrations with the 3.2 based ROM.

Good news, we have the 3.2 kernel ready to go even though we don't have official kernel source from Samsung.

Bad news, I don't think we have stable 3.2 base yet...at least for the WiFi version...not sure about the 3G model.

I'll probably go back to 3.1 as well and sit tight until we get an official release. Thanks for your observations and comments.

Being first is not always best

Sometimes we should remind ourselves that "patience is a virtue."
But for all us GadgetAholics, we can console ourselves by knowing
that we can warn others AFTER we've taken the plunge into
"unknown waters."

Happy Thanksgiving !

P.S. Forgot to mention that I also tried the V3.2 for 7510 (10.1" WiFi Tab)
which made me thankful that we can reboot into ODIN mode.

What kind of performance issues are we talking about? Mine seems fine. Are those benchmark scores not good? I dont notice any lag that wasnt already there.

One thing to remember about this ROM is that it is deodexed so it will be slow the first time you boot and the first time you run any system applications. After you use stuff once, it will be fast the next time (boot will also only suffer once).

I didn't have any major issues, I just feel that 3.2 on kernel 2a is less fluent than 3.1 on kernel v1i. Stock for stock it seems the same way to me (3.1>3.2), but the overclocked kernel is able to hide performance issues mentioned by some GT8.9 reviews. The difference is very subtle and won't be noticed by most. It probably has something to do with Samsung and their modifications of Android 3.2 and Touchwiz. The benchmarks I ran were the same on 3.1 and 3.2 and I have had no issues with any hardware on either version. In my mind, the issues are very small and unnoticeable by most.

I hope this helps clear things up for you and others that are wondering and experimenting.

Update: I am back on this 3.2 WiFi ROM and don't have any issues. I did two things different this time. First, I wiped data (factory reset). Second, I installed my new updated kernel v2b. While the latter may give some smoothness improvements, it is the former that is likely making the difference. When I did this the first time, I was lazy and didn't wipe data. The ROM install itself wipes cache and dalvik cache, so this was the same for everybody, but the data wipe may have been a wildcard and may have been worse for some due to the settings they had etc.

If you do decide to do this (wipe data and upgrade), you won't lose all your SDCard install zip files, but it will erase system settings (WiFi networks/passwords), email accounts, browser bookmarks, installed apps and their settings. You will boot into a new tab this way and start from scatch. You can use Titanium Backup so you can backup on 3.1 and restore apps quickly. Also, make full CWM backup and you can just go back to 3.1 as it was if you like.

I'm definitely happy and staying on 3.2 now. It sounds like the Overcome ROM is also flying along on 3.2 as well after his last update. Moving onward and upward!

Although I did a complete wipe before installing this one, I still feel 3.1's a bit smoother at landscape and other animations on my tab. I shall wait for another leak hopefully by Christmas. Thanks once more for your efforts

thank you
