Preroot CWM method issue

Hey, I did the CWM preroot method for jellybean, Everything works fine except my sd card is constantly disconnecting, This is actually making my battery drain really quickly. My battery will last about 5 hours without me even using the phone. Battery stats tells me that media is using between 80 and 90 percent of my battery. I know media takes care of sd card. Has anyone seen this issue. What i did was flash ics ftf, root, flash recovery (CWM), flash jellybean prerooted, kernel from jellybean stock ftf, lte from ICS baseband. Wiped date everytime. Everything should be working, but. Does anyone know if or when LT28i jellybean will be coming? And a real root method to go with it.

[Sony Xperia S, Acro S, Ion] luisoman2000:
Yup. You can flash lt28h or i firmware without issues ( you would need to flash the at baseband for lte though). Search the forums on how it is done. It wont affect carrier unlocking( running lt28h jb on my carrier unlocked lt28at)

This topic has been discussed already in other threads.

Please ask Google first, before posting in THE WRONG THREAD :(

That said,

if you unlock the SIM you will have all the LT28i frequencys available on your LT28at.

However you will still have a bootloader that cannot be unlocked, no access to fastboot.

Any ION can run any version of stock Sony ION firmware.

All android versions for the LT28 -i -h -at (GB - ICS - JB) will work on any hardware versions of the ION, LT28 -i -h -at.

LTE requires either LT28i or LT28at firmware or baseband.

[Sony Xperia S, Acro S, Ion] luisoman2000:
Well it has some bugs, but it is a lot smoother and uses less resources than ics. For some the lag while recording full hd videos is a deal breaker, but personally i dont mind. Check the bugs threaf for info and if you don't mind them go ahead and flash.
[Sony Xperia S, Acro S, Ion] bADiTCH:
Jellybean Yea!

To answer your question yes it is worth it. Although I went a different route in upgrading my Ion to JB. I used flashtool to flash JB 6.2.B.0.211 stock on my LT28at then flashed only the LT28i baseband from ICS 6.1.E.3.7. I then used BiN4ry's "root with restore v31" to root JB. Worked like a champ, considering that I soft bricked my phone somehow using Spectre51's instructions during my first attempt, but that was my fault for deciding to do it at 1am a few days ago.

Here's the forum link to Bin4ry's v31 root_with_restore:

http://xdaforums.com/showthread.php?t=1886460&highlight=xperia+ion

I also wiped the phone completely clean and did not restore anything on my phone from a backup. There is stutter in full 1080p video but like everyone else 720p works flawless.

Update: Working on putting together a "don't panic" guide for those that end up messing this up like I did at first.

I'm sure it's just a placebo effect, but it does seem a little smoother...also for whatever reason there seems to be two file management apps. That aside the stock rogers bloatware is included.
[Sony Xperia S, Acro S, Ion] :
Is that possible to do the same trick (see below, from Spectre51's other post) to keep LTE available?

My phone is running the LT28h ROM and maybe I can flash the Rogers ROM with baseband only?

If you have an LT28i or LT28at and would like LTE with the LT28h rom then once you have flashed the above go back into Flashtool and flash the latest LT28i or LT28at ftf. UNCHECK Wipe Data, Wipe Cache, Wipe app Log, and exclude everything EXCEPT for baseband. This should put LTE support back on the phone but keep the LT28h system.
[Sony Xperia S, Acro S, Ion] raven4757:
Yes it should work mine and my wife's phone still get lte but we are not using the Rogers Rom but I don't see why it would work
[Sony Xperia S, Acro S, Ion] :
Thanks for the info, is there any downside of using Rogers ROM? (for example locked WiFi Hotspot?)

Maybe I'll flash Rogers ROM, root it and then install Recovery just to make sure the LTE is there.
[Sony Xperia S, Acro S, Ion] bADiTCH:
Other then bloatware in the Rogers ROM that is the only downside. Currently loving 4.1.2 LT28h rom on my LT28at. My battery life is great and thats with my wifi connected allday. I would however recommend installing Location based Wifi from the Xperia T, Here's the forum link

http://xdaforums.com/showthread.php?t=1933346

Been using it first with ICS and now with Jellybean.

So far it seems the battery life has been exceeding what it was with ICS but it's only been a week. Don't miss any of the AT&T junk at all. That may also be the reason for better battery life as well.
[Sony Xperia S, Acro S, Ion] zackspeed:
I keep losing my lte on my at. It has happened three times now and I have no idea why it does it. One thing I have a problem with is I cant just flash the base-band to get it back. I just recently tried flashing the rogers jb and then went to the pre root deodex and all was fine for a few days. Sure enough I look at my network settings and lte listing is gone again. Now it still has a lte icon in the status bar but at 6 to 8 mbs its not lte. When it is working I see 20 or more.

I guess now I am going to try the rogers jb and de bloat it and de odex it.
[Sony Xperia S, Acro S, Ion] optimumpro:
There is nothing (other than drivers) preventing you from flashing Rogers JB baseband. Just load Rogers ftf and exclude everything but the base band. Also untick wipe everything etc. Now, when you are done flashing, go to settings and set your network to LTE/GSM/WCDM. You should also go to your APN settings and make sure that your APN protocol is set to IPv4. It has been reported that many applications stop working when you have both Ipv4 and Ipv6 enabled. Also, keep in mind that in certain areas LTE signal is weak and you can have 5-6mgb download speed.

Again, I had problems with crappy LTE until I flashed Roger's JB baseband.
[Sony Xperia S, Acro S, Ion] zackspeed:
I am very well aware of that. Its not driver issues I know that for sure as I can get it working fine. My issue has been it just randomly dropping the lte listing in network settings. I have lte almost everywhere I go in town now and have been making sure to test in a solid connection area. I am really starting to wounder if it is something in my back up causing it but that does not explain why it is fine for a few days or weeks and then just vanishes. The base band will flash with out any issue but like I said it does not fix the issue.

Again if I try just flashing base band again it will not fix it. I have to start over again in fact just yesterday I tried to restore a good nandroid only to have lte vanish again. It is very odd to say the least. I am starting to wounder if it is one of my apps that I am restoring.

So I have now flashed the Rogers firmware and showing lte in settings but still getting network communication issues if I try to test the speed. Second try rebooted the device. I am going to drive this firmware for a while and see how it goes. Just need to root and de roger I guess lol.
[Sony Xperia S, Acro S, Ion] bADiTCH:
I have not had any LTE issues with using the LT28h JB rom and the LT28i ICS baseband. It may have something to do with your backup. I did a complete wipe and do not restore backups. So from a clean install point LTE seems to be fine.
[Sony Xperia S, Acro S, Ion] optimumpro:
"I am starting to wounder if it is one of my apps that I am restoring."

That should be easy to check: do straight installations and restore data only, as opposed to restoring both applications and data. Also, it might help to format internal and external storage as there may be left overs from the previous rom. Usually you don't need it within variations of the same kernel but as you move to a different one (like jb), it would make sense to format.
[Sony Xperia S, Acro S, Ion] zackspeed:
Yea I am slowly doing a manual restore to the de odex h. I did find a few files that where quite a few com.sony files that do not need to be there so maybe that's what it was.

Edit: Well it did it again today and seems to be related to data switching. Out of the blue it lost connection and sure enough when I looked in my settings LTE preferred listing is gone again. I am thinking it is mod related maybe but no one but me seems to have this issue. Every time it does it the phone starts running quite hot. Guess I get to start all over again :(
[Sony Xperia S, Acro S, Ion] NOOB Kris:
Sorry for my ignorance, could you tell me the difference between Roger and Generic firmware?
[Sony Xperia S, Acro S, Ion] luisoman2000:
Rogers is a carrier firmware with bloatware. Generic has no carrier bloatware.
[Sony Xperia S, Acro S, Ion] NOOB Kris:
Thank you! What is carrier firmware?
[Sony Xperia S, Acro S, Ion] luisoman2000:
Carrier firmware is the one released by carriers(Duh!), if your phone is carrier branded (AT&T, rogers, verizon, etc) your carrier is supposed to be the one to release software updates for the phone(they receive the update form the manufacturer and then add their own apps, widgets, etc).

Usually carriers take a lot more time to release updates, so it's not always a good idea to get a carrier branded phone.

Hey how do you unlock the LT28at? I called att and they said to factory reset and it should be unlocked and no code needed. That doesn't sound correct right? I am wanting to sell the phone and overseas is a bigger market. It's like new refurbished, only used it a couple weeks.
[Sony Xperia S, Acro S, Ion] luisoman2000:

[Sony Xperia S, Acro S, Ion] petes67bird:
Thanks Luis. I wonder why att stated that an unlock code wasn't necessary
[Sony Xperia S, Acro S, Ion] zackspeed:
Seems like they misunderstood you. From what they told you to do it seems they thought you forgot your pin so reset and it is not there. You need to ask for sim unlock. Also I would be careful as most US carriers require that you keep your device active for 30 days on the account and if you don't they can charge you full price for it. So I would look into that so you don't end up in a pickle.

I would just flash to 211 Rogers that way you don't have to worry about base band. If you really want the H version then flash 211 rogers then flash 211h and make sure to exclude base band.
[Sony Xperia S, Acro S, Ion] Spectre51:
Yes just flash the lt28h through flashtool and check the box that says exclude baseband. Should work fine. Would be best if you wiped the data and cache as well but you can try unchecking those if you want to try to keep your data.

I use completely stock ROM, with the only change being I use honmai home. It gives me a full auto rotate home.
[Sony Xperia S, Acro S, Ion] zackspeed:
To say it is just people modding that are having issue is wrong. The stock H rom does have a issue with the AT device. It has been documented quite a few times by quite a few users. The 1080 lag is there but only in the preview. The big thing was the garbled call issue and complete loss of LTE settings. This was all on a complete stock rom. Once the LTE settings disappear you have to start over with a clean flash to get them back.

At the moment I am running a custom Aoba 96 port. I have stuffed most of the stock stuff back in with the full Honami apps, settings, and framework with out any issues. The Rogers based 96 port has been one of the best things yet. The whole reason it came to be was from so many of us having issues with the H based 96 ports done by others.
