Is it correct that some said "If you unlocked the skyrocket , it would not work again on att&t LTE if you decide to go back to at&t service and your area has LTE " ????

Thanks
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Shanghai.Knight:
Hi! Thanks so much for this thread. Very informative. I have read all the posts.

I just bought a Skyrocket, and would like to stick with the standard ROM for now, which I read should be fine. My main concern is with Battery life, stability and with turning off LTE. Is there any way in the stock rom to disable LTE? That was unclear from these posts.

My theory is that staying with Stock rom would give me the best stability and battery life. My HP tablet is what I use for playing with ICS and nightly builds, but I cannot afford downtime, hacking around with my phone. If disabling LTE is not possible in STOCK, I guess I need to research Juggernaut, SKYICE, Official CyanogenMod and TeamChopstics...

THANKS!

good radios

I have read through this thread and the "CWM flashable modems" thread in the hercules forum ( http://xdaforums.com/showthread.php?t=1426001 ) but I have a couple questions.

I'm running the latest nightlies of CM9 on the ATT i727 skyrocket and I'm on Tmobile currently.

Is anyone else having problems flashing most of these modems on cyanogenmod 9? I keep having "sim not inserted" messages after flashing. I wipe cache and dalvik before flashing the modem zips with CWM touch, but once I see the "sim not inserted" message I pretty much have to restore a nandroid backup, flashing a previously working modem doesn't get my radio working again.

So far the only two that have not caused "sim not inserted" errors are VK1 and LC8.

Those of you on the latest CM9 nightlies and the i727 on Tmobile, what modems are working for you?

EDIT: The Telus and Tmobile modems from this thread worked: http://xdaforums.com/showthread.php?t=1705617

In Virginia I get 6 Mb down using the Tmobile modem and maybe 3 Mb down max with higher ping times with the Telus modem. Both burn through battery like crazy though.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] BobSilva:
It's so odd... How we all seem to get different results...

On my i727 / CM9 Nightly / T-Mobile / Honolulu, HI combination, the Blaze 4G radio is the only radio that gives me any data bandwidth. The best I can get is about 1.6 Mbps. With ULVE1, the download speed was 1 Kbps -- literally.

So, I see no rhyme or reason to the choice of radio unless it's location sensitive...

FWIW,

Bob

Turns out the skyrocket uses the same msm8260 chipset as t-mobile's s3. they may be using the msm8260a. this may signify the newer gpu. they clock really close from what i have been reading. does this mean we now have radios designed for this chipset, t-mobile and ics? anyone try flashing the t-mobile s3 radio to the skyrocket? am i on to something or has this been looked at?

Yeah i might be wrong on chip set compatibility and brick my phone or I could be right and it still could work. I on the other hand am the last person that should be experimenting with these things. I think I might be wrong tho. Its a different soc s3 vs s4 krait which is some new a15 hybrid. Odds are it won't work.

The confusion is from how nearly identical the model numbers are for what may be very different socs.

Well today I jumped off ATT and trying out Family Mobile (Tmobile) through Walmart. Im currently on the official ATT ICS with my unlocked skyrocket and didn't even have to flash a different modem. Internet works fine but clearly a step down from ATT 4G. It took about 5min for the activation to allow phone to allow to call out. Took about 15min before the internet started working but do far the call quality is good. through my work I get a discount so its only $30 month for unlimited talk, text, and web. I'm glad I'm able to keep my skyrocket :)

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] speeddevil:
Checking for updates will do nothing. You have to plug it into the computer, and use Kies to check for an update, or flash it using odin. Odin is an acceptable way and wont void you warranty like flashing a different rom could.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] lesd777:
Yes that's the app, and I believe it will show you an ip address to type into your PC browser's address bar. It should then open up the kies page. I didn't get the prompt from kies either, and i don't know if it's because my phone is unlocked but i did get an email from ATT stating the download was available, but trying to update through the phone update option and through kies, I was never prompted to update to ICS.

If your phone is rooted, then I do believe there is an ODIN file in the forums here for official UCLF6 update.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] waxworkz:
yes i am rooted, but my odin knowledge is very limited. just enough to do the rooting
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] lesd777:
First, backing up your phone its always a good idea.

In the skyrocket development section, it's the 2nd sticky thread from Vincom. everything you need is in there.

http://xdaforums.com/showthread.php?t=1652398

scroll down to the section " HOW TO RESTORE STOCK FIRMWARES"

download ODIN 1.85

then scroll down to " WHERE AND HOW TO GET STOCK FIRMWARES"

and assuming you have the skyrocket , you need the "ATT ICS 4.0.4: I727UCLF6_I727ATTLF6_ATT"

Once downloaded, extract the files. If you can't , then you may need 7-zip to extract them and he's got the download link to 7zip as well.

Once you extract that zip file, you'll have a fairly large file named"I727UCLF6_I727ATTLF6_I727UCLF6_HOME.tar.md5". If that's not the file name, it should still be a tar or tar md5 file.

Then all you need to do is open ODIN 1.85 and look at vincom's screenshot and read over that section carefully on what not to select.

power off your phone, then plug it into your pc via usb then hold the power, volume up, volume down all at the same time. When the phone vibrates let go of power, but keep holding volume up and volume down. This will get your phone into ODIN mode.

To continue, press " volume up" just like it says to.

you should then see your ODIN screen turn YELLOW in the ID:com section.

Click the PDA button in ODIN and target the tar or tar.md5 file you extracted from the zip file.

Make sure you only have what's selected on vincom's screenshot for ODIN!!!

Click "Start" and the process takes about 8 minutes. Once complete, the phone will reboot on it's own.

That will get you to ATT stock ICS, and the radio worked ok for me on Tmobile ( phone unlocked of course).

The Blaze Modem is what I just flashed to and I'm getting better download and upload speeds.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] speeddevil:
I could be mistaken, so take this with a grain of big salt, but I think the one that is not modded installs something called rils. You will be unable to install a different modem and have it work correctly. You have to restore your android from a backup or reinstall ics. I could be way off, but for some reason I was under this impression. The modded one does not contain rils. It wont let me upload it, I think the file is to big.

For some reason...i think your right. Something is weird right now. I did this same thing last night. Through Odin...then factory reset and got 4.0.4 from there.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] r3a1ist:
I think u need root to flash radio using a recovery like cwm. U seem new to this game be careful when u use Odin. It shouldn't be this difficult. Root ur phone, flash using cwm and test. Revert if needed with stock radio handy. I guess mod file is the one u use. I just read up on it months back and saved the radio for when I ever decided to jump to t mobile. What I gather is the mod file is working for folks.

SO...as per what i ask....if i install CWM...and then ROOT...can i keep what i have now which is the Stock 4.0.4and add that Blaze radio Mod to this? Is that possible. I just want the REAL new stock firmware...but have at least 4G or a H signal. This E is terrible. Im getting 35 kbp download speeds. VERY slow.

Another curious question..if i use the Blaze mod Radio..if i go into *#2263#...will it have the 2G...3G...4G...options in it? Or will it not...an i just notice a lil boost? And will the Edge "E: be gone?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] r3a1ist:

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] r3a1ist:
Of course, depending in the method you use. Most root methods don't involve the flashing of a new rom.
