[Q] X10a rooted firmware issues. - XPERIA X10 Q&A, Help & Troubleshooting

I just bought a used X10a today, Not my first android but my first rooted phone, (bought it rooted and unlocked. It is running 2.2.1) and there alot of issues and I just can't seem to find out what exactly I need to do so I can actually use this phone. First off it was originally a AT&T phone, I use Cincinnati Bell so the unlock is a must.
My first big issue is no matter what I am doing swiping through menus, screens, options you name it, it is laggy and jittery and half the time wont move just goes nuts for a few seconds.
The next issue is I can not for the life of me get 3g to work, edge works but no 3g. I used the exact apn settings as my other phone which is an unlocked tmobile and works fine but not on this one.
my last problem is I am missing tons of the factory installed apps, I do not mean the bloatware and irratating things that come on phones that arent needed, but things that I really need like a music app, the maps app, the email apps, all of that. All I have are the bare bones needed to run stuff, dialer, and messaging. That wouldnt be to big of a deal but nothing on the market will download it says download unsuccessful every time for any app, So i am not able to get all the things i am missing.
Also I do not know if it matters but I feel I need to mention it, The About Phone section on the phone says it is a x10i but the phone is actually an x10a so I do not know if that has anything to do with my problem but throwing it out there.
I really like this phone but I can't use it like this. What I need to do is either downgrade it to a rooted 2.1 so I have everything and it works or get a good 2.2 rom that will actually work. The problem is I have never rooted a phone so I do not know what steps to take let alone adjusting a phone that is already rooted.
So would it be possible for me to downgrade to a proven working 2.1 rom or is there a 2.2 rom for this phone that is proven to work and not cause all these issues I am having right now?
All help is greatly appreciated,
Cody

Cody,
CBW uses TMO's 3G infrastruacture (1700+2100 frequency bands). X10a is equipped with a radio that works on AT&T's 3G bands (850+1900) but not TMO's. X10a does not work on TMO's (therefore CBW's) 3G. It's a hardware issue. For 2G you won't have any problem. Therefore the fastest data speed you can get with X10a on CBW is EDGE. On the other hand, X10i should work on CBW 3G.
I would say that what it says on the "About Phone" section probably doesn't matter. I tried a tons of custom and stock ROMs available here with a variety of radio firmware but I haven't experienced any difficulty with AT&T. Then again you are trying to use X10a on TMO.
http://forum.xda-developers.com/showthread.php?t=1012380
This should help you with some of your other problems. Rooting and flashing a ROM on X10 is very very easy, thanks to all the developers here who contributed.

With my phone already being rooted and flashed would I still do it just as if it was all stock?
My only other question is would a generic 2.1 rom still leave the phone unlocked for use with any sim?
Thanks, Cody

I'm not a tech but from what I understand and I did in the past, once SIM is unlocked, the phone will stay unlocked no matter what firmware you flash, including a generic 2.1 ROM.
Rooting and recovery are different. When you flash a stock SE 2.1 ROMs, you will lose root and recovery. That's where the flashtool comes in handy to get root and flash recovery again.

[Q] Samsung SGH-T959 Network Failure

My Samsung SGH-T959 Will not connect to the T-Mobile GSM network. All other functions appear to work OK. The phone worked well enough until I needed to use it in Britain last week. Until then, it was stock from the store, locked to T-Mobile USA.
I needed connectivity so I unlocked the phone and used it with a Vodaphone (lebaru) pay-as-you-go sim. At first it would not register with the provider, but I gave the phone to the agent (some Arab guy in a small shop...) and after they kept it overnight, it worked. On returning to the US I put the original SIM back in the phone. Now it won't register with T-Mobile. Sometimes it finds ATT towers when I scan for network providers, sometimes it does not. It never sees T-mobile.
I have verified that it is unlocked, and done a hard reboot and washed away the internal Flash storage. The behaviour does not improve. I have tried two known-good SIM cards.
I have read many posts that seem to indicate that others are having similar problems, but I haven't seen any answers (or even explanations).
Can anyone suggest a solution?

Ok, I guess that I'll need to use Heimdal, as I don't have windows. But where do I get a 'stock' image to load? If what I have is not stock, how do I know what it is? And if I come to the point of having to load alternate 'ROMs', which do I choose. There seem to be so many caveats.
What I find really perplexing is my phone's sudden inability to lock to the tower corresponding to the sim provider I'm using. With other phones and modules I have used over the years, this was ever an issue. You put in an ATT sim, the device tries to connect to an ATT tower. You put in T-Mobile or Vodaphone, then it tries to connect to the corresponding resource. It almost seems as if there is a small hidden file somewhere in the bowels of the beast that overrides the sim's preference.
Still trying...
Ok, after much wailing, flailing, and gnashing of teeth, I have sorted out more of the vocabulary of this forum, hopefully attached it correctly to the relevant concepts in my head. I feel that I am making progress of a sort. I have also installed Heimdall under Linux, Odin under Windows, Kies and a variety of minor tools. I have tried them cautiously, but avoided any rash actions. I believe that I will make a unbricking cable for good measure.
But my phone still won't connect to the T-Mobile (US) tower. Scanning for 'networks' only shows ATT, and I'm pretty sure that I can't even talk to that using an ATT sim.
My working theory is based on the events that got me to this point (but still far too little knowledge about my phone) and goes as follows:
When I had the phone unlocked, this was done properly, but my T-Mobile (US) 'MODEM' (which I assume to be the signal processor code that controls the physical layer radio interaction) was not able to negotiate a session properly with the Vodaphone (UK) tower. I took the phone back to the person who unlocked it, and he/she/it realized the problem and updated that part of the code, allowing me to connect with the 'network'.
I never mentioned to the phone-unlocker that I only planned to stay in the UK for 10 days. It didn't occur to me that upon returning home, I might encounter the flip side of this problem. And if he/she/it happened to think of this possibility, he/she/it figured I'd be well out of his/her/whatever hair by the time I noticed. Which I am.
So my operating assumption is that I need to reverse the initial modification of my firmware, restoring the initial functionality to the 'MODEM'. I have yet to find a trove of alternative 'MODEM' code, but responses to queries by others seem to imply that one exists. I am reluctant to attempting to flash the device back to the original state, mostly because I am not sure what that state was. I've downloaded a bunch of stuff (i.e. Odin + .pit files) but I'm nervous about whether they are really the right ones for my phone.
Can anyone tell me if I am on the right track?

You should download the AIO Vibrant Toolbox since it have all the instructions and files you need to revert back to stock. Its pretty easy.
Instead of typing so much, odin back to stock. Man I hate fast typers. /crazy.flailing.arm.tube.man

[Q] How to get 3g from provider on different baseband?

Hi,
since no one want to answer my question here: http://forum.xda-developers.com/showthread.php?t=1192804
I would like to approach this another way.
Is there any possible way to obtain 3g network from your provider? Rogers only works with 2.1.55 baseband as far as i know as i have flash the other baseband before and losing 3g network completely for example 2.1.62.
Is there a work around solution as i don't understand how these thing works and assuming Rogers will never update gingerbread consider, they are dictators of our phone.
I eagerly want to know as i am a huge 3g user and i am throwing out 3g usages under 2.3.3 as we speak.since 2.1 stock force close me every few min oppose to the current 2.3.3 which in favor of my broken/dying phone, i would like to stay on 2.3.3 as much as possible.
thanks

Calling all Canadians! Bell Telus and Rogers users.

Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

Bell note here. Been. The at & t roms with no problem.
The only issue that I have is the Yellow Pages crap that appears in my contact list as well as at& t bloat depending on the rom. Easy enough to deal with though.
Aside from that, it's been perfect.

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...

[Q] Trying to get ics 4.0 on my Samsung Showcase

So after reading through all the posts about flashing my phone to ics from droidstyle's post, i ended up trying to flash my phone from 2.3.5 (which I was not able to update normally by my crappy carrier) to one of the ics roms. Which ended up giving me zero 3g access. My question is are their specific files i can pull from a working Showcase with the latest carrier supported os, to put on my phone after i flash it to ics to get it to access 3g again? My problem is all these roms and what not tend to be based off verizons phone the fascinate. Which as far as i can tell are almost identiacal except a few differences. I dont have verizon as my carrier but a little kansas based one called nex-tech.
there is a 3g data fix.zip floating around here somewhere in this section...thats what u need.
*edit found it

go to rootzwiki and download the stock eh09 or ei20 package then follow the going back to stock part of the guide.

most likely you will have to call your carrier and have them do a esn swap or activate a old phone on your line then switch back.
I went down to the office and they did a swap of a phone they had in the building. No luck what so ever. My girl friend and i have the same exact phone, minus a small hardware update between them. Ive completely erased all of my phone and flashed a generic showcase rom and updated through their website. They programmed it and all that jazz but no luck...

I had a Sprint Epic for a brief time but live in an area where it was using Nex-tech's towers since Nex-tech is part of Sprint's roaming alliance. I was running custom Froyo roms from XDA because there was no official Froyo release at the time. After a few months it had the same problem with losing 3G. I spent two hours on it with Sprint's tech support and never got it to work again. They even sent me a refurbed phone and it failed right out of the box. They wanted me to drive to the nearest store to have them activate it, which was 1 1/2 hours away when it should have been able to activate thru Nextech's system. Needless to say I ate the ETF and got a Fascinate.
My theory is Nextech has some kind of black list that shuts off data on phones it thinks are roaming for an excessive amount of time. Maybe switching to an ICS Rom designed for the Fascinate might have triggered that.
Good luck with getting it working. The main thing that keeps me from going back to Nextech is their lame tech support and huge repair times instead of refurbished swapouts. I keep hoping when Nextech's contract with Sprint is up next year maybe Sprint will come out here.

[Q] Desire 601 International Data Functionality

Hey guys,
I have a pretty unique problem and im not sure there even is a solution, but here goes.
The story is that I had been living in Canada for the last 7 months or so and bought myself a shiny new Desire 601 from Virgin Mobile (its a zara_ul). Since then, I have managed to brick it hardcore style, but i was able to ressurect it after 4 months of fruitless attempts through various odd files, sheer dumb luck, and the RUU from mrplowdans google drive (super props by the way, you saved my phone good sir!). I had to SuperCID the phone in order for the RUU to stick.
So it goes without saying that im now running the Telus version of KK (i updated through the usual OTA once i had returned it to stock 4.2.2) on a VM phone. All good, no issues there. Ive since returned home to Australia, unlocked the phone so it works with an Australian carrier, also all good. Im able to make calls and send texts no issue.
My problem is with mobile data. It seems to be having an issue connecting to my carriers 3g/4g. Initially, there was nothing at all, just the bars in the notification bar telling me that i had a good connection to cellular. No little superscript 3G though, and in settings, although mobile data is 'On', it is showing connection failed. Adding a custom APN appeared to work slightly, the 3G appeared in the notification bar and in settings, mobile data was shown to be 'connected', but still no dice when i try to connect to the web or download an app.
Now i vaguely understand the principles involved here, I get that North american carriers use a different radio frequency to, say, Europe, and that differs again to Australia. My question is, is it on the software side? Would it be possible to find an Australian Radio.img for a desire 601 (i dont even know if they sell them here), flash it, and all will be fine and dandy? Or is it the physical antenna inside the phone that is set to receive only a certain frequency? Im not expecting someone to go and find me a working file or anything, i know most of you live in Canada anyway, but im looking for someone with a greater knowledge of these things to find a theoretical fix.
I know I rant a lot, but in the scheme of things im willing to let this problem slide considering i only just un-bricked it a few days ago AND managed to root 4.4.2 (a significant achievement given my non-existent knowledge of android), but it is a nuicance and if theres something simple i can do of course i will.
Thanks in advance for any help <3
EDIT: Ive since done some googling and discovered that they do sell these phones in Australia, and that the Network specs for it and the canadian model that i have are almost identical, many of the frequencies are the same on both. Leads me to assume that its software sided, the telus radio.img is telling the phone to not see non-canadian frequencies.
