Hi all,
I'm newish on the block when it comes to jailbreaking phones, and I've got a few questions before I jump into the mix and possibly screw my HTC dream up.
1. Does having root access inpose any security holes? In other words, if I jailbreak my phone, will it get hax'd from hackers?
2. My HTC had a RC8 build of android 1.1 before I upgraded it to the optus suppiled OTA update of CupCake (1.5). Is it still possible to downgrade despite this version of android?
3. There's a few custom roms of the Os around and I like the addition features they provide. Do I need to be worried about flashing a us custom rom on a aus (uk?) Handset? Or do custom roms have no actual region setting?
4. What are some good custom versions of android?
Alright, I'll be awaiting a response so I can start jailbreaking my phone. Cheers all!
1. No
2. Yes
3. Dont know about that one, im on US lol
4. CyanogenMod
Good Luck!
Alright, I'm getting ready to take the plunge.
I was looking at CyanogenMod and it looks awesome, is there any simple step-by-step tutorials on how to install it? I've read ways of installing it, but I just want to be sure I install it the correct way and not botch something up.
What version should I use? CyanogenMod v3.6.8 or v3.9.7?
After 3 Days of reading and digesting all of the information I could find here, I need help in clearing up a few questions. Hopefully no one will rip into me too bad but here we go!
1)Ive seen an "official" USA wifi update on the forums here, has this actually been DL'd in the US or was it taken from the EU release?
2)For any of us that have been running DJ Steves Honeystreak and have downgraded with NVFLASH back to stock Dell Froyo 2.2.2 been able to just DL official HC 3.2 from dell via factory update methods?
3)In reguards to the service tags not matching on USA wifi models that have been downgraded with NVFLASH back to factory froyo 2.2.2. If a USA factory upgrade is attempted , has there been any problem with that? Specifically related that there is indeed a USA update available.
For some these questions may seem elementary. But with all of the reading that I have done I cant seem to find definitive answers to these questions.
As always thanks in advance for all of the help I find here. And any help would be greatly appreciated.

In regards to question 1, yes the Wifi version for the US has been officially released, however depending upon the build will determine whether or not your tabled has been tagged as for an upgrade.
On question 2, if you completely converted back to stock then you shouldn't have an issue with update as Dell can't see that you were not anything but stock.
On question 3, try doing a system restore to see if the tablet's tag changes to what yours should be, if not a couple of solutions have been posted in the past few days on what you can do to make it match. The update may not even look at the system tag but simply at the build.
Hope I've provided some answers to your questions, if not someone else may come along and add to this thread.
I just bought a GSM unlocked Galaxy S3 (edit: i9300, android 4.0) and went with T-Mobile's online pre-paid plan. It's all stock except for having root access through CF auto-root. Edit: the device is not rooted, just using CF auto-root to give apps root access. Everything is still stock as far as I understand how CF auto-root works. The device is still running 4.0 and no updates are available. Are we being left behind? Or was there an update, and if so, why can't I see it?
Edit: I haven't checked KiesAir, and I'm not at a machine that can allow me to do that with my phone. I'll try that tonight after work, but if somebody could chime in, I'd still appreciate that.
Apologies in advance if this is posted in the wrong forum or if I'm asking a questions that's been asked a hundred times already. I've tried digging in the forums for an answer, but it's far too time-consuming and produces little or no results.

Hi Diashi!
1. Q & A Forum is the right place to ask - no reason to be worried.
2. You bought the LTE version (GT-I9305) ??? - 'cause you only wrote Galaxy S3 - if so, this is the best place to ask.
3. We're not being left behind - but if you got an unlocked and rooted device, you will not receive OTA's (Over The Air Updates)!
You'll have to flash them manually with Odin (Windows), or Heimdall (Linux), or through CWM recovery.
So the first thing you have to do is, check if you have a GT-I9300 (no LTE) or a GT-I9305 (LTE).
And if you still have questions > feel free to ask!
Welcome on XDA

KuliX

It's an i9300, which has LTE. The phone is not rooted and there are no roms installed. I simply installed SuperSU.apk with CF auto-root to allow root access to apps that require root. I did this so that updating the OS wouldn't be an issue in the future, but i don't know yet if this is absolutely the case.
Thanks for replying KuliX. Anybody else who wishes to weigh in, it's all appreciated.
Edit for clarification.

To your understanding:
Go to Settings > About device > model number
GT-I9300 = no LTE
GT-I9305 = LTE
there is definitely no device with Model number GT-I9300 AND LTE!!!
THIS IS VERY IMPORTANT FOR YOU!!!
CF-auto-root means = your phone is ROOTED - not just for some apps which require root - YOUR WHOLE DEVICE IS ROOTED!
The only different is, you do not have a custom recovery like CWM.

Ahhh, I see. So if KiesAir turns out to be fruitless, should I try to install 4.1 somehow through Odin the same way I installed auto-root? I'm not even sure where I would look for instruction to do that. Oh, wait. What about 4.2? Is there a version of that for i9300? Sorry for being such a grunt, but answering these questions should help other people in my same situation.
Also, the wiki for the i9300 says it has voice over LTE, but I'm guessing not data. That's a real disappointment. I thought the i9300 had everything. It's not a deal breaker though.

There is no Android Version higher than 4.1.2 - that's the latest brand new firmware!
You can get it here
http://www.sammobile.com/firmware
And I would suggest you to switch over to GT-I9300 forum - cause you will run into heavy problems if you flash the wrong firmware!!!
And YES - you can flash newer firmware with Odin!
I'll give this a go and might report back later. You've been a great help, KuliX. Thanks!
I am happy to report that my phone was able to update from 4.0 to 4.1 through Kies (not KiesAir) - while I was using CF auto-root - without a single hitch. Everything is in place as it was before the update: rooted apps, settings and all.
Special thanks to Chainfire for making CF auto-root, an my life a lot easier. And thanks KuliX for providing some valuable info.
Hopefully this will help somebody else out there.
A little confused, do you have the 9300 or 9305 as the 9300 does NOT have LTE.
Go to settings>About device
I am a little concerned for you as if you have been sold the 9300 as having LTE it does not! So you may not have something that you have paid for.

The seller on eBay had a long stat and feature page which said the phone had LTE. Technically, it does - for voice. But not for data. This isn't something that I was aware of until KuliX brought it up. I'm not disheartened, though. T-Mobile seems to have plenty of HSPA+ in Los Angeles, and by the time they get real LTE up next year (probably summer or later), some new Samsung whatever will be out and I'll just rotate to that.
The i9300 I bought was for $620 (roughly), and included tax and shipping. It's the best price I could find. Little details like this are something I'll consult with members on XDA in the future, before I buy. This was really just my mistake.
Edit: sentence structure.
As long as you are happy! That is what counts!

that can be changed it can do it on data too voice and data use the same paths thrue the modem and radio you just have to flash it to the firmware
of the SCH-T999 to the radio or edit it to include the data portion the radios and modems are same between phones im allmost 95% sure of that
based on my resarch of the phones and also on the I9305 the same. T-mobile doesnt have 4G or LTE they use the 1700mhz band Odd Tiering
both the SCH-T999 and the Samsung GT-i9300 have the same radios and modem its my theory that if you add the firmware from the T-999 are the same , now dont get confused the Roms are diffrent because quad core vs dual core and the Snapdragon S4 processor is in the T-mobile version but that has nothing to do with the modem or the radio modules, its all programming.. because if you look at the spects for the T-mobile side version T999 version it doesnt even list the LTE for regional now guys let me say some thing why would they use LTE for voice when GSM has more then enough for the band space for voice? that makes no sense...its the FCC regulation and certification of operation, its just programming guys that is all.
Originally, I posted this on the beginner's thread, but no one would help me
So I decided to make a new thread.
I have an unlocked HTC One 32GB purchased directly from HTC, and discovered that it could not use the wifi-calling function of t-mobile. So, I managed to unlock the bootloader and root, but don't know what to do now.
How can I just add the wifi calling option in the settings, and restore the apps I lost while unlocking the bootloader?
Also, can I get official updates from HTC, even though I'm rooted?
Please, make the answers user-friendly (I'm very new to this community and android- first android phone!)
Any help is very much appreciated.

You need a ROM that supports wifi calling. After you unlocked your bootloader, you need to either flash the stock T-Mobile ROM or a custom ROM that has wifi calling built in. Keep in the mind that a lot of the newer ROMs using 4.2 base do not support wifi calling yet so you need something with a 4.1.2 base. I'm using ARHD 9.4 and wifi calling works flawlessly. Hope this helps.
As the subject stated, I have AT&T version of the Galaxy S4 Active. The phone is unlocked (code provided by AT&T) and now I have a T-Mobile SIM card.
I want to do Wi-Fi calling, but couldn't find any information in this forum or when Googling it.
Can anyone provide step-by-step information on this? Preferably, I don't want to install a custom ROM - I use stock ROM (rooted) and it has been stable so far.

Check this thread for T-Mobile WiFi calling ( http://forum.xda-developers.com/showthread.php?t=2302313). You've got two things working against you though. First you have the AT&T version of the phone, so ours locked down and you can't fully flash ROMs to the phone. You can use SafeStrap to flash ROMs but because of the bootloader being locked your stock with the stock kernel. Second, nobody has got T-Mobile WiFi calling working on non T-Mobile ROMs. So basically you can't do it with the phone you've got.
Thanks for the detailed information. Looks like it's not doable given the locked boot loader. :sly:
