Hello guys,
I am a new owner of the GT-P7320 Galaxy Tab 8.9 LTE and I'm a bit confused about the naming and available roms.
First off, what's the difference between 7300/7310 and 7320? All the guides in this section, including the "one-stop ultimate guide" (http://forum.xda-developers.com/showthread.php?t=1406137) are written with 7300 and 7310 in mind. Is there anything I should be aware of, or I can simply follow the guide with my device as well?
Also, I noticed there are separate roms for 7320 in the development forums, yet I managed to find only 1 thread - the OTA ICS one (http://forum.xda-developers.com/showthread.php?t=1901664). Why is that? Did I miss something, or there are no roms available for the device yet?
Is there a point in flashing the OTA ICS 4.0.4 right now? Is it AOSP, or has got the TouchWiz interface? How stable is it? I was really looking forward to ICS just for the sole purpose of being able to use Chrome.
I tried using search and did some research on the forums, also I am quite experienced with rooting and flashing other android devices - but the 7320 got me really confused out there.
Thanks in advance!
The most important difference is that 7320 uses Qualcomm's Snapdragon architecture - to power the LTE chip - while 7300 and 7310 feature a less efficient NVidia Tegra. The LTE is also the least popular amongst the 8.9 Tabs. But we've got root, we know how to deal with OTA updates that Samsung doesn't release to public, and we have Arlicc's ROM that is basically stock Touchwiz ICS with some tweaks.
ICS runs great on this Tab and really there's no reason to stick with the Honeycomb.
Yes, actually, the Arlicc's ROM got released after I made the thread I'm using it right now, very satisfied so far - you are right, ICS runs great and smooth. In fact, it seems faster than 3.2!
Thank you very much for your kind answer! There's one thing I still don't understand though - I have always thought that Qualcomm Snapdragon is a CPU and Tegra is a video card/module - how come Snapdragon in 7320 is more efficent than Tegra in 7300? Aren't 7300/7310 using Snapdragon as well?
Both are "system on chips", basically a CPU, GPU and radio stuffed into a single chip. The 7320 CPU is a 1.5 GHz (compared to 1 GHz on 7300/7310) dual-core. Apparenty a Tegra 2 device wouldn't be able to handle an LTE radio.

Hello,
I joined the xda community about a year ago, first with my Htc Magic, then with my HD2. I have the opportunity to get a Samsung Galaxy Tab from some carrier for little extra money of my current Internet plan. And for 10 €/month more, I could get the new 10.1 version...
Although I do know that logically I should choose the 10.1, I still consider the 7'. Why ? Well, it would be cheaper at first. Then, I like the 7' size more and I'm not sure I would need Dual-Core processor for Internet surfing ! Also, the 10' model's phone app is blocked by the carrier, while it's not for the 7'...
But I digress !
Before to sign up to the plan, I'd like to take the pulse of the community. It's something I always do prior to purchasing a new device. I'm use to the HD2 orgy of Roms and OS and I must say that the less-furnished Development section for the Tab leaves me thinking. I don't doubt of the quaility of the ROMS but I wonder if devs are not already leaving the Tab's development for more recent Tablets and devices.
So...If you are a serial flasher like me, is the Tab a good invesmet ? I'd love to flash later CyanogenMod releases when there will be actual Tablet versions of it (for the moment, CM7 on a tablet is still in its early months) and of course Honeycomb or even better, Ice Cream Sandwhich. Will there be dev's at that moment ? Of course, I know it's not an easy question to answer but it's more about the community strengh until today actually...
Thanks and see you soon hopefully !
cm7 + tablet tweaks = win.
with roms, ill take quality over quantity, even tho there are only 3 2.3 roms, they are all badass.
the tab7 has been the best tech device ive ever owned, i have an ipad but it lives in the draw, its just way to big todo anything with other than using it in bed or on the toilet.
I suggest get the 7inch or wait for the new 7inch (who knows when that will come)
the only negative i have is that theres so many new devices out with dual core ect... but so far it hasnt stopped me from doing anything that these newer devices can do (you can play tegra games via chainfire) but eventually it will become an issue i guess.
The carrier matters.
More dev work is being done for the GSM variants at the moment. But spacemoose1 does have an alpha hc rom and dev continues in that.
Thank you for your anwser and I do agree about quality over quantity...
I'm aware of tablet tweaks from CM7, I already used them on my 4'3 HD2 screen but that not much in comparison of the many tweaks TouchWiz seems to bring to the Android 2.2 UI. Of course, overlay means slower device but oh well...
Is it possible to easily save/back up the stock Android Rom it will be shipped with in order to restore if I need to return it under warranty ?
Thanks !

Yeh, you can do a nandroid backup, or just find your stock firmware, from the website sam-firmware (i think thats it) or just brick it
I've been going bonkers trying to get my p880 flashed to 20a. I tried the LG-KDZ Hacker method first (many times), then the KDZ_FW_UPD method, which also failed. Finally, I tried using LGFlashTool which also failed, but the failure log gave me a hint as to why:
"Invalid Target P880 <> P880g"
Has anyone successfully flashed a Canadian 4x with a non-Canadian firmware?
Can anyone think of a way to do so? Or is there a reason I shouldn't?
Mods? Just delete thread.
Nevermind; I've done a more indepth search and come across all the previous unanswered threads. Mods--you may as well just delete this thread.
Yeah, good luck finding any info on the P880g. No one at XDA is working on it, so the best we can do is pray that LG releases something official for it.

I asked on their Facebook page and they replied "At this time there is no scheduled upgrades for the Optimus 4X within Canada."
I was a bit surprised at the hostility towards the P880g posts I found. It's not like our variant has its own forum. It's also not like variations in devices are uncommon. Back when I had a G1 (HTC Dream), the Canadian version ran different S/W but could run USA roms without issue--providing your radio and bootloader matched. But that was just a S/W issue. We *may* have different hardware. However, given how small the Canadian market is and that the P880g has only been released here (as opposed to the dozens of countries the P880 is available in), I'd be surprised if our *hardware* was actually different. I haven't been able to track down what chip the P880 uses, so I don't know if it's capable of 1700. If it is, we might be alright running p880 roms. If it isn't, then we'd need some real dev work.
The real issues right now are the locked bootloader and the model check. That's what's preventing us from seeing if a P880 rom would run. I'm no dev but if I can figure out how it does the model check then I'll try and flash v20a and see if I lose connectivity.
Now that makes me curious... check this comparison: http://pdadb.net/index.php?m=pdacomparer&id1=3314&id2=3972
The only difference between the two is Band 4 on the P880g, and Band 9 on the P880... plus Android 4.0.4 vs. 4.0.3 (a minor software update). The listed chips are the same. So what is it in the hardware that makes a difference for frequencies? Is it even hardware, or simply a ROM limitation? Do they have physically different antennas?
Perhaps it is simply a matter of flipping a couple bits in a P880 ROM to enable Band 4, and disable Band 9 and the model check. I wish I had a shred of the technical knowledge necessary to experiment with this stuff.

The 'chip' in question is the radio/wireless chip, rather than the cpu/gpu. It's not typically listed on spec sheets, and is the sort of thing you need to do a teardown to find out. For example, if you check out this teardown: http://www.ifixit.com/Teardown/Nexus+One+Teardown/1654/2 , the Qualcomm RTR6285 is the Nexus One's radio chip. Sometimes radio chips will support more frequencies than they use. If the P880 and P880g have the same chip, then accessing frequencies is a software matter and easier for a dev to deal with.
I'm no dev either, but hey, devs are made, not born. I like my P880g as is, but I'd really love to be able to customize it more and or update it as time goes by and 4.0.4 begins to seem a bit long in the tooth.

I read a Google + post by cyanogenmod stating that after android 4.2, they will stop support for tegra 2 devices. I was wondering what is going to happen to our beloved GT i9000. Now i know that the GT i9000 isnt a tegra 2 device but the post got me worried, and i wanted to know what you guys are thinking?
i dont use tegra, so i got no point bout that, but its quite dissapointing as they prefer abandon their user rather than supporting them
Sent from my GT-I9000 using xda premium
Apparantly it has somethig to do with tegra 2 devices being NON-NEON and android moving towards devices with NEON support
Update (Only affects Exynos 4):
This doesnt affect us (GT i9000) directly but affects Galaxy S2 users. Apparantly cyanogenmod have had problems with Galaxy S2 support since CM9/ICS so they are only getting Nightlies for the forseeable future. I wonder where that leaves us GT i9000 users?
The Tab Pro 10.1 has tons of development activity. Tab S 10.5 not so much (i.e., practically none as far as roms). Just private messaged the top Developers in the Tab Pro forum asking if their work there can be ported to the Tab S. Hardware other than the screen is very similar. Seems like it should be doable (although I'm not a developer and there may be complications of which I am unaware).
Anyway, flare fired, emergency beacon activated. Let's hope we can get some port love here and get a solid rom or two going.
** They may need some guinea pigs to test things out. But these are extremely experienced recognized Devs and you should take some comfort in that.
UPDATE: All development for the 10.1 is for the SM-T520 which is the Exynos 5 wifi model. Should be no issues there.
TAB PRO 10.1:
Chipset Exynos 5 Octa 5420
CPU Quad-core 1.9 GHz Cortex-A15 & quad-core 1.3 GHz Cortex-A7
GPU Mali-T628 MP6
TAB S 10.5:
Chipset Exynos 5 Octa 5420
CPU Quad-core 1.9 GHz Cortex-A15 & quad-core 1.3 GHz Cortex-A7
GPU Mali-T628 MP6
Identical.
UPDATE:
Good news folks! Our little project here has resulted in a working, smooth and pretty dammed fast rom for the 10.5 (US Version). It is still in Beta but based upon my experience, everything seems to be working.
Special appreciation to @Shaheer who came here from the 10.1 Pro Forums and without the benefit of his own device built a working rom for us. My thanks also go out to all the smart people who teamed with him to make it happen.
Go give it a flash. It only gets better from here
http://forum.xda-developers.com/galaxy-tab-s/development/sm-wip-rom-t2832360
** Update: Have just heard from @mrwookie6379 in the Tab Pro 10.1 forums. He has also expressed interest in developing for us. Cool.
There is a big difference between tab pro and tab s.
Maybe I'm wrong but the development is only on snapdragon version of the tab pro...

** OP amended.
If any of these devs ported CyanogenMod or aosp, I would love to take a look at their device directory. I am getting closer with my port but running into a crash with surfaceflinger and the mali driver.
My wife would be happy if I got this working so I could stop obsessing.

i have the 10.1 and have been considering the S and so looking around here to make my decision. i will say that the Exynos component is probably going to prevent us from every seeing CM11 becase they dont develeop for it. also there is very little dev for the 10.1 and what little there is sees very little updates and most roms seem to be abandoned.
none of the 10.1 to date have developed far enough to make me want to install them yet.
you can look here to see them and then check OP for last update and you will see what i mean
Ah the mondrianwifi, I took a look at that one initially but unfortunately it had enough subtle differences it wasn't much use.
Edit: So just did some digging, still can't find any ports of cyanogenmod to 10.1 (SM-T520). Ill spend a little bit more time digging but as far as I can tell the closest port has been the exynos 5410 samsung galaxy s4 which is what I forked my current port.
When I said there was no development on the Tab Pro, I meant the T520 of course, as the T525 is snapdragon...
It seems I was right, I didn't see any cm11 work for the T520.

By "development" are you referring only to CM? That's a pretty narrow definition of development. And of course no CM for Exynos but lots of TW based roms as you can see from the Tab Pro forum.
CM is awesome and clean and light and fast but you also give up the entire TW ecosystem including multiwindow which is a big price to pay for a little more speed.
Yes TW can go to the junk, CM is the best thing we could have on our tablets.
I consider TW based Rom more as tweaks / tuning than real development.

Well using that argument, CM is just tweaked Android.
Yes of course ...........
Well so far no responses to my private messages from the developers at Tab Pro forum. Next step will be to post in the actual threads and ask nicely for help. These guys probably get a million PMs so I'm not surprised not to hear a response.

And android is just tweaked linux. Though the difference in porting AOSP/CM to this device versus modifying the current rom is like the difference between building a model rocket from a kit and launching a shuttle into orbit.
Really anyone who knows how to extract/build a system.img can build a rom for this device in under an hour. Super simple. Though thats not what I am personally interested in accomplishing. There is way too much stuff in the samsung rom that triggers my paranoia, up to and including the clause in the license that says something along the lines of any data we collect can be used to evaluate your eligibilty for hiring at samsung.
I am getting AOSP/CM on here or this tablet is going up for sale. If anyone is interested in helping out I have a couple github repos up and making progress on a daily basis.

Unfortunately the 5410 doesn't use the mali gpu which is where I am currently getting a crash. I just imported a bunch of code from the arndale_octa (Raspberry pi like board that uses the 5420 SOC) and waiting for my build to finish.

5420, 5422, and the 5800 use the T628.
As for the crash it looks like its happening somewhere between hwcomposer, gralloc, libEGL, and libGLES_mali. I put that fork on pause while I try take a look at the arndale_octa mali code.

Lol, argue with me about what, that only CM development is real development? The entire Development section of any Samsung forum is dedicated to non-CM based roms and represents 95% of all development for that device - and simple they're not.
The purpose of this thread is to draw rom development to the Tab S 10.5. Denigrating TW developers and comparing their efforts to model rocketry doesn't help. As far as CM being the space shuttle, that ship is already built and on the pad, you're just looking for the launch codes.
The question: Which is the best option (conjecture):
a) CM11 on a Tab S SM-T800 (Exynos 5420)
b) Touchwiz on a Tab S (Exynos 7 Octa 64bit) -unreleased
c) Touchwiz on a Tab S (Exynos 5433 32-bit locked) -unreleased
Links:
[REDACTED] - I can't give you links since I've not enough posts yet.. google "Tab S 5433" and you'll find some links to the new stuff I'm talking about, news broke around Oct 2.
details:
Since I live in Seoul, I'll be able to pick up one of these new bad boys if/when it's released. However, that would mean returning the T800 I've just ordered as soon as it arrives; I only bought it because of Suzook, Nvertigo67, and Baracudda77777's efforts to port over CM11, but I'm guessing the re-released Tab S won't be compatible with their Rom.
The articles seem to suggest that the re-release tablet will have the 5433 (now renamed the Exynos 7 Octa) but it's possible that it will be 'locked' into 32 bit mode.. not really sure if that means forever or until they update touchwiz to Android 5.0.
Just don't want any lag.. what would you do?

I personally would just stick with the T800, like you mentioned they are making great headway on the CM11 rom. How much performance difference(if any) would there be between the two?

Not sure if it would make a difference at all so I put the question out there. Perhaps future proofing to some extent?
The new chip is touted to be ~50% faster (and easier on the battery) but if CM11 runs perfectly smooth on a T800 already then I guess I don't see much pointed in going faster than perfectly fast
Well I read about it only being released in korea/parts of asia. Not sure yet on when it will be in the u.s. Doesnt matter really since its just changing chipsets for better improvement of performance. But nothing was mentioned about battery life. The tab s i have now has great battery life since im rooted and debloat some apps. And I dont really need a faster tablet since this is just fine for me. So battery could possibly be an issue in the new tab s is what im asking.

The problem with the lag in current models is touchwiz thats causing it. Until you change launchers, theres no lag. Unless you wont care of haveing root a couple weeks of whe the new tab s comes out go for it. Just make sure you check if the battery lasts as long asadvertised. There have been reports of bad batteries in some tab s models right now. I wonder if there will be much development for the new tab s.
