So in the span of an hour I had rooted and unrooted my phone. Did this for a couple reasons really. First being this is my first android phone and I wanted to experience the process. Second being I wanted to try the sixaxis controller apk.
I live in Canada and imported a phone via amazon.com purchase. I believe I got the Taiwan model as right out of the box it was defaulted to a chinese character setting. During my unroot process, I flash the UK base into it. This happened because of two things. One being I wasn't 100% sure I had the Taiwan model or not when I was selecting the rom to flash back to. And two, I was following the video in the rooting section which included resetting my flash count to zero and changing my phone from KOR to BTU.
Since then I've run some tests. Cell service is looking good, data is working. Only thing I noticed that I lost in the process was the language keyboard(canada) was available in the chinese stock rom, but I have to use the US one for this stock.
Is there anything I should be aware of? Should I not get too attached to this stock rom and try my best to flash back into the original?
Is there anything I should be aware of?

Nope. Rom's are completely interchangeable within the boundaries if the i9300/i9300T hardware.
You can even go as far as cherry-picking the System from one ROM, the CSC from another, the modem from yet another...
(Only within compatibility, Axxx and Bxxx ROM's are not compatible, Bxxx being newer)
Great, good to know. Thanks.
actually just found something, I can no longer access the menu button from within the wifi settings screen. As a result I can't select frequency band, etc.
It's possible that some ROM's dont include that feature. If it's on auto you should be fine anyway since it _should_ prefer the 5Ghz band over 2.4.
AOSP Roms don't have it either, no issue here =)

First of all, I apologize for being a PPC noob, but I asure you, my technical skills are high and my PC familiarity is high too. I have done alot of searching/learning on here and other forums (and the internet in general) and think I am ready to take the plunge.
Background Data
----------------
HTC 6800 Windows Mobile 6.0
ROM Version 2.17.557.0
Radio Version 1.64.00
ROM Date 11/20/07 (geesh, I just got the thing)
Garmin Mobile XT
Provider: Cellcom (non-major / tier 2 provider in Wisconsin. I get great coverage from them in the area I spend 99.99% of my life in)
Mostly I want yes or no's to the following questions, but if you want to educate me, believe me, it is appreciated. The potential of this device feels massive, but right now it is too cumbersome/unreliable (I am sick of soft rebooting this darn phone).
1) Is there any way to backup my phone in its entirity so if I need to revert to the carrier provided rom/config I can? Including can I revert back to my original bootloader?
2) Can I use the newest Sprint ROM on my phone (WinMob 6.1) even tho I am not a Sprint customer?
3) Would I be better off using one of the ROMs provided by this forum?
4) If I upgrade the phone, I should no longer need Garmin's bluetooth GPS transmitter, correct?
Thanks in advance to all who help. I see the potential of this tool and really want to try and unleash it.
Afternoon, onioneater! It sounds like you've got a generic ROM that is often used by minor, or local carriers (I'm down in Illinois with a local carrier, had the same ROM as you). There are many, many ROM upgrade options available for you. I talked with a technician from my carrier about upgrading, and as it turns out, you could probably flash to any major carrier ROM as long as you do not allow customizations to run. Check out the tutorial on flashing to custom ROMs over at the XDA Wiki.
http://wiki.xda-developers.com/index.php?pagename=TitanRecentHome
Although I did not back up the original generic ROM, I wrote down all EPST and provisioning settings for somewhat of a backup. As I said above, a customer with my provider flashed to a major ROM, for Sprint, and got it to work. But there is a wide expanse of options with custom ROMs too. By the way, as long as the radio version is higher than 3.35, internal GPS is unlocked (newest Sprint ROM and most newer custom ROMs work on a radio of 3.35 or higher). Although with custom ROMs, you have to manually unlock the bootloader and manually install a radio with a MicroSD card that is 2GB or less. Check out the link above for more. On a side note - A few months ago I was in the exact same situation as you before, being a noob and all with a generic ROM - you can keep in touch with me through E-Mail if you have any more questions [email protected]
Thanks dfc. What ROM did you settle on using? I was thinking about using dcd3.2.6 with the recommended radio and bootloader that dcd recommends. Seems like a pretty safe way to go and sounds like many people go that route.
Have you made any of your own ROMs yet? I am going to keep reading and studying and trying to figure out a way to fully backup the phone so if I have to revert due to company policy or anything like that, I will be able to.
I was very surprised to get help from someone from Illinois being that this is Packers/Bears weekend. If it makes you feel any better, I watched the movie Brian's Song the other night and I still get teary eyed. LOL.
Im not a techie on phones or tablets so please bear with me on this,
I upgraded my UK tablet s by changing the region and using the US ics upgrade, But for some reason (which I havent delved into yet ) Cant seem to root it.
However now the UK ics with 3G is available I would like to flash that.
Do I need to change the region back to UK or can I flash over the US version, what happens if I change the region against the instructions.
Is it even possable?
As I remember I used Odin to flash.
I would like as much detail as you feel Im entital to, Im begining to not be able to see the wood for the trees.
Hi. Ics on the tablet s can not be rooted for the moment, so you are stuck on US ics for now.

Thanks for that.....
......Definative reply, im_iceman, Its not the US rom, I'de quite happily use that ad-infornitum, its the lack of 3g, i did'nt realize when i flashed it that the rom would not take advantage of my 3g sim card, I thought it was just the built in 3g that wasnt catered for, still there you go, my punishment for not researching properly anyway TY.
Yes, the US ICS ROM's are purely WiFi and do not feature support for any of the Tablet's external Internet functions. Without root, you won't be able to change region and therefore can't return to UK region until ICS is rooted.
Also, unfortunately, Odin is a Samsung-only tool and there is no equivalent for the Sony, especially since there have been no leaks (which is what gave us Odin), and the bootloader and system image are highly locked down. I'm not sure there is even a partition dump for the Tablet S...
Ah, must have used Odin for my Note, its no biggy really, i can wait meanwhile everything I did with the Tablet s I'm doing with the Note its got all the facilities just a tad smaller screen.
But thanks for that.
You'll just have to set up a WiFi hotspot on your note and hook up to that when you're out of WiFi range.

Okay, so, I've done a fair amount of reading and searching about modems and RILs, including other forums, but I've still yet to find the specific information I'm looking for. (Most of the stuff that I've found relates to the i9100.) So if I missed the relevant post, I apologize, please direct me there.
That said, here's the deal. I've got an i777, which I have unlocked and am currently using on T-Mobile. I've flashed the stable CM 10.1.3 (Android 4.2.2). Its baseband is UCLE5. It's running well. I have few complaints, except for occasional low signal.
I've already seen this thread, with the different modems available: http://forum.xda-developers.com/showthread.php?t=1336958
I lost the link, but I also found a thread, possibly on another forum, where a T-Mobile user reported better performance with baseband UCMD8. I'd like to try it. I think I can manage flashing it on my own via CWM.
However, I've read in a bunch of places that it's also important to have a RIL matching the baseband version. I found a thread that gives a terminal emulator command to find your current RIL version (getprop "gsm.version.ril-impl"), and mine is "Samsung RIL(IPC) v2.0", which is apparently from Gingerbread.
So, my question is this: Should I also change my RIL? If so, 1) where would I get the appropriate RIL for the i777 with CM10.1.3, and 2) how would I install it, preferably without performing another wipe, reset and ROM installation?
Thanks in advance for your help!

You have nothing to worry about - just flash the i777 modem you want via recovery; you don't have to wipe anything, it will work fine. I wouldn't worry too much about RIL; over the two years of changing modems back and forth I've never encountered any problems regarding RIL (except for some wakelocks, but that's more to do with bad/weak signal than anything else).
To be clear, I'd still be happy for input from anyone regarding the i777's RIL, but I did go ahead and flash UCMD8. I've already noticed something new; my phone now seems to drop from H+ to 3G fairly aggressively when I'm not actually using it, then go back to H+ when I do, where since flashing CM10.1.3, it previously connected only at H+ or E. I imagine this is a battery saving measure. I'll have to see how it behaves for a few days.
Thanks for your response SteveMurphy. By the way, what baseband/RIL version do you use, if I may ask?

I'm on UCMD8,
The reason you're seeing 3G more often is because with the newer roms you have the ability to better control your network modes. For instance, if you want to use Edge you can manually switch to 2G mode. It's possible the older firmwares (GB, ICS...) had this option but I really can't remember.
Galaxy S Backdoor
So it seems my question about RILs was unintentionally timely, as Samsung's RIL for Galaxy S devices contains a backdoor that's been verified with proof of concept.
https://www.fsf.org/blogs/community/replicant-developers-find-and-close-samsung-galaxy-backdoor
http://redmine.replicant.us/projects/replicant/wiki/SamsungGalaxyBackdoor
I'm not sure which version of Samsung's RIL they tested, or whether they tested the I777, but it seems most Galaxy phones are affected.
Hope someone gets to work on this soon.

Suspiciously timely, yes.
here's another take on the back-door claim:

My EVO 4G LTE has, with all custom ROMs, lost stability after a month or two, developing different arrays of performance quirks or problems.
I'm interested in if there's a way to test the hardware on the phone? I'm tired of switching / reinstalling ROMs.
At first I thought the problem was that the ROMs were unstable but I've chosen from the bet ones available - PACman, Viper, a couple others I can't recall right now. The phone is rooted via Dirty Racun FYI...
Currently, with Carbon, the problems consist of:
With screen lock off, when waking the phone via the power button, something on the current screen will activate, whether it's an app shortcut on the homescreen, or a function inside of an active app.
Setting for LTE / 3G will not stay on 3G (LTE coverage is spotty enough that I just don't use it)
Random crashes / resets / bootloops; occasionally the phone will freeze on the loading screen with the Carbon logo and require me to hard-reset it.
Once in a while it's ignored my alarm clock.
Usually when dialing out, the phone will hang and fail to connect / ring, and I'll have to hang up and dial out a 2nd time to connect / ring through.
With ROMs I've used in the past, the arrays of problems have been different but of similar nature. At first I was inclined to blame the ROM in use but as my phone is the common element between them, I'm interested in how I can determine if I have a lemon on my hands or what.
Thanks for reading this.
Go back to stock rooted and see how it runs.

I'm not unwilling to do that, but I have extra time this weekend to run diagnostics as well if there's any method by which that's possible? It seems to take a few weeks for problems to start developing when I install a fresh ROM.

Any such diagnostics when not on a stock ROM can be issues with the custom ROM, not the device. If they occur when on stock, that helps determine hardware may be at fault.
Most of the AOSP ROMs suffer from kernel and data issues because they use the same base. You might want to try the Android 4.3 RUU as well since that's the latest we have for the device.

Ah, thanks for this. I didn't think it would be reasonable to blame the ROMs across the board. I'll look into the 4.3 RUU.
I use an ATT unlocked variant of s21 5G
1: It overheats excessively, you cant even game on it
2: When gaming, the touch sensitivity is very low despite turning on increased sensitivity in settings
Anyone know why or give a possible solution, my guess is because its still stuck on One Ui 3 and Android 11

I can't say why with any certainty, but can say I would never want a carrier rom on my phone, I always switch to an 'open' version as it rids you of the carrier bloat and and restrictions etc they put in their roms.
Granted, that doesn't work for everyone as they are 'tied' to a specific carrier. So, if that's the case, I'd look for info about whatever that specific rom / carrier problems exist.
But, if you can go with any carrier you want, go with one like Mint Mobile, which allows volte, vowifi, and 'open' rom phones, like the S21. It's easy enough to find how to use Odin to flash an 'open' rom also.
One additional thing you would accomplish by doing the above; you'll discover if the issues you're experiencing are the fault of the current rom, or they are hardware related. Not sure how else you would test that hypothesis other than doing the exact above?
good luck
