[Q]Downgrading T999V S3 JB 4.1.1 to ICS 4.0.4

Hi Guys,
I'm really new to doing all this stuff. Got my phone rooted on a stock mod and am running the latest TWRP. I'm really unsatisfied with the JB 4.1.1 in terms of speed and would like to downgrade back to ICS 4.0.4. I've looked at a few threads on how to do this but there isn't really a direct answer. From what i've read it's just flashing the old stock rooted rom using Odin but is there anything else I have to do? Also all the other tutorials seem to be for CWM which I haven't had much success in installing. I just don't want to trip the flash counter. Thanks for any help.

ODIN is the only way to downgrade from a 4.1.1 to 4.0.4. You can get more information from here --> http://forum.xda-developers.com/showthread.php?t=1771687
If I were you, would try other ROMs such as Frosty, DaRTHSTALKER, and WICKED first before spending so much time downgrading. There are some steps you can do to speed up your phone including removing un-needed apps such as weather, stock, SCloud, freezing the sync apps like google account (only sync when needed), or over-clocking your CPU.

+1 for debloating. That's the problem.
What issues are you having with getting CWM on your phone?

Thanks for the link. That was the thread I used to initially root my phone. I'm a little iffy on putting on custom roms as i've read that some of them mess up the calling and tethering and etc.
I've also run the de-bloater using the recommended settings. Should I go further? The phone itself isn't that slow for the most part but it lags at times. I find it extremely annoying when it lags when i'm typing a text message. Which is one of the main reasons i'm even trying to do this.
Also would downgrading trip the flash counter? Thanks for all your help so far guys. :good:

It sounds like some apps is constantly running in the background. Find out what apps is causing that issue and freeze it to see if it helps.
Anyway, in regard to the flash counter, you can use triangle away to reset the counter before downgrading.

Jellybean is way ahead of ICS in terms of batterylife and speed, the problem is on your end, try many of the rom's in the dev section, my rom i easily push 4 hours screen time. Make sure you stick to wifi as it uses less juice, turn wifi off when your away from a hotspot, keep bluetooth and gps off if your not using them. Limit the app's you have running in the backround

That's weird because I never had this issue when I was using ICS. My RAM usage is never usually past 700-800/1.5gb. I always clear it and clear active programs as well. I would love it if I could just fix the issues without having to downgrade but I really don't know what it is at this point aside from the upgrade that could be causing this. I also have uncapped internet from my cell provider so I never use WIFI. Those things are always off. It's not so much battery life i'm concerned about it's sheer speed. I also don't use bluetooth and once in a blue moon i'll use GPS. Needless to say, I also shut down every night when I go to bed.

[Q] I got s-on, but really want to flash the new radio!!!

Hello all.
First time poster. You guys got a great site here, you do great work. I need some help....
First, I'll tell you what I'm working with...
HTC EVO 4G
CM 7.2 Rom
anom ra recovery 4.3 smelkus by team dirt (before I started experimenting I had clockworkmod 5.0.2.2 recovery, but will stick with amon ra now)
HBoot-2.18.0001
Radio-2.15.00.12.19
What I've been trying to do is flash the new radio. Every road I go down leads to a dead end.
-I've tried going back to the sense rom and accepting the system update, it wouldn't update for me
-I've tried downloading a sense rom and flashing that, it flashed, but offered no firmware updates
-I've tried renaming the radio update file to PC36img,zip and going to the bootloader, but I have that dreaded S-on so it wouldn't take
-I've tried installing from zip in the recovery, that wouldn't work
I've tried several other things over the past couple of days. But, due to being frustrated (sometimes to the point of being close to vomiting), it is all running together right now and is difficult to outline each thing I tried right now.
Most things I've seen say I need S-off to do this. But, then I google the steps involved in getting my s-off, and that seems like such an insane and convoluted process that I think there HAD to be a better way out there. (I don't know why the unrevoked people wont make a product that works with the hboot 2.18.0001, but that's neither here nor there). I've also seen threads referencing relocking and then unlocking the phone again...those are months old. Someone has to have a better way by now.
Basically, I am having a very difficult time wrapping my head around the concept that this can't be done with an S-ON phone either through the recovery or through the ADB. There's got to be a way. What is it I'm missing?
Before anyone asks, here's why i want to do it...
Both me and my wife's phones have radio 2.15.00.12.19. We're constantly getting 1x no matter what we do. A few days ago, I rooted a friend's phone. Same phone, same rom, but I noticed he is getting 3G. I investigated, and he has radio 2.15.00.01.15. Since I would like for me and the wife to have our 3G back, naturally I'd like to get this radio flashed.

I have the new radio and it made zero difference in anything

Getting S-off is not that hard. Just follow directions. My 10 year old nephew can do it.

To be clear, you *must* have S-OFF to flash radios.
You're *sure* your friend has the "same ROM"?
Because the most obvious explanation for your heartburn is that Sprint often *does* drop any given phone (regardless of radio ) down to 1x: CM based ROMs accurately report this, while most stock or stock-based ROMs just ignore it and report "3G" all the time.
Is this really your only reason for switching radios?

First questions:
Yes, absolutely certain. I even used the same downloaded file to flash his as I did mine and my wife's.
Your second paragraph...yeah, I've been reading that. But, I'm thinking that "You can't win if you don't play" and I have to try something.
And, yes, this is my only reason for wanting to switch radios.

Your 10 year old nephew has probably had more success than I have finding a walkthrough that didn't contain one more more dead links to needed files. So far, I have not been as fortunate.

Captain Throwback lays it out pretty well.
The advice is free....the bandwidth, not so much

Well, thank you for MOST of the responses.
I did what I didn't want to do here...I finally had some luck finding an S-OFF tutorial that didn't contain dead links. The links were mostly to outdated files, but I did the best I could with it. Now my phone has S-OFF
And, just as with HipKat, flashing the radio didn't make any difference at all.

If I'm not mistaken, there's a way to change your network priority settings.
For instance, If you're on Boost Mobile, Sprint has a lower priority for these devices to maintain a better service for its higher paying Sprint customers.
I've never changed these network settings myself, so some one else might help you if this is your issue.

Hey, other thing to consider is that Sprint is upgrading the network in your area. My experience in the las 6 weeks was that during the day on monday thru friday the data signal was awful, switching from 3G to 1XX and sometimes all day in 1XX. Check if there's a pattern when you have no data or is bad.
Now I have awesome data speeds even in 3G, I mean, in PR standards
Cheers

unfortunately, it has been constant 1x since I flashed the roms (CM7.2 for both of ours, several roms on mine alone but I'm back to CM7.2 now).
My wife has observed that she doesn't notice a difference, positive or negative, with her data speeds. I have to say that I have observed the same. I am really starting to believe that Sprint has deliberately mislead us with their 3g icon in the stock rom. If this is indeed true, isn't this like...you know...a crime or something?

you're on a Sprint PRL right? (I've noticed whenever I force CM to roam on "affiliated networks" all my data is 1x)
Sprint should give you 3G at least sometimes, CM or not. Have you observed this outside of your usual home area?

If by "home area" you're referring to geography, since I've flashed my rom I haven't left town really. Just work, home, and the usual errands. If you're referring to Sprint vs. Competitors...I don't know. My network system select was on home only. I have now set it to automatic. I'll toggle airplane mode and see how that does, I guess.

Maybe this is one of those occasions where updating your PRL and profile would be useful?
(Just to remind, this can only be done from a Sense ROM, so you may want an expert to chime in before you spend any time making a nandroid, flashing (or nandroiding back to) a Sense ROM, doing the update, and restoring back to CM)

tried it. About four days ago (give or take a day) I flashed back to my rooted stock rom. I attempted to update it. It would download, but on the reboot it would hang and give me a picture of the green little android guy standing next to a big triangle with an exclamation point in it. I googled and googled and googled, but could not find an answer as to why. I reattempted that about three times, same result each time.
So, I downloaded a stock rom (rooted) and updated the PRL successfully, profile successfully, tried to update firmware but told there was none, and I didn't try update the rom itself of course. Of course the sense rom told me I had 3g, but when I flashed back to CM7.2, same thing...the 1x.

That android with the red triangle typically means your recovery has been deleted.

Poor service on custom ROMs?

My dad has the same phone and his isn't on a custom ROM, he's on stock, and he always has amazing service no matter where he is. I, on the other hand, never go above, like, a lone bar in my area.
Is it the PRL? modem? What do I have to do?
Sent from my LG-LS970

It may be. If you're running a stock based rom just go into your settings/system updates and update your prl.

I actually have the same problem. Anything that isnt stock or stock based seems to keep me completely out of service. try lifeless rom if stock is just too much for you

I'm having the same problem as well. I always go to stock ROM and update my profile and PRL before updating a custom ROM. For some reason i always have full bars on stock but the second i move into a custom rom my signal drops and i have 1 bar to no bars at all times. I can still text and make phone calls but i just hate that im always having such poor reception on custom roms. So updating PRL and profile does not really help because the sprint signal is always low.
Im glad that I am not the only one having this problem and others have it too. That way devs can look into this and figure out a solution. I posted about this 1-2 weeks ago on the rootbox thread but it seems i was the only one who had this problem

This is the case with a lot of phones and AOSP roms. The signal reporting and display are different than stock, but the actual signal strength is the same. It was the same with my Evo after switching to CM, Deck's and Strike. If you can still make clear phone calls in the same locations that you could with stock, then you have nothing to worry about. Obviously, if you don't have the same quality of call, then you have other problems going on. Try grabbing an app from the Play Store that will give you actual numerical dBm, so you can know for sure.

[Q] Sprint GS3 Signal Reception

So this is my first flash to a different ROM on my GS3. I have been rooted for a while and decided I wanted to try a different rom on 4.2.2 coming from 4.1.2 with touchwiz. I am using the Dirty Unicorns 4.2.2 ROM and I noticed my signal reception is spotty at best. I am talking data and voice together. I flashed back to my 4.1.2 touchwiz stock rom and the reception went back to normal. I did some research on this issue and started looking into APNs. I noticed the file on the Dirty Unicorns rom is full of VZW, CREDO, Sprint... but the stock Sprint ROM only has Sprint stuff. The differences in the 2 files, only looking at the Sprint settings is slightly different still.
Is this my issue? If so should I use the stock APN file?
I am using the stock MD4 baseband and my PRL is 25015. Any thoughts or troubleshooting steps are appreciated.

I did some deeper research to find that the signal reception seems to be reporting incorrectly in the Dirty Unicorns ROM. I downloaded an app from the play store called network info II. This reported my cell reception to be the same it was on the stock MD4 touchwiz rom. I also think that the signal bar is reporting the faulty reception listed in the about section of settings. I made a few phone calls and ran Pandora on the cell network with no abnormal loss of quality.

Try a app in play store
Signal Check Lite
Gives a lot of info and signal strength for data too

I like that app better than the other one I was using... Thanks for the tip!

Back to my issue, it looks as if the phone is reporting correct numbers in the signal information fields. What it looks like it is showing is the data connection it is using. I also, sometimes, find my phone on LTE even when I connected to wireless seems interesting. I am not sure however about the signal bars at the top of the phone. Rarely ever do I see them rise above 2 bars. Maybe somebody from an AOSP rom or CM rom could chime in with an answer.. even a DEV!!
FYI: Would have posted this in the development forum but I didn't have enough posts at the time. I am also sharing my info just in case it isn't around or it helps someone else.

[SOLVED] Same problems over here
edit 10/10/13 [SOLVED]: I found this thread about Team Sonic Modem Flasher Tool. There are five available radios in the super easy package. 1-4 came up with error messages, "No SIM card," or no signal with an Unknown Baseband in the phone settings. The fifth one, "LI3" radio solved my problems.
The Flasher Tool doesn't have a means of backing up your current radio. Seems like as soon as you start installing these other radios, your original one (mine was an MB1) was gone. BTW, my phone Baseband was a long string of letters and numbers. The type of radio that you've got is the last three characters.
I was also experiencing problems with other ROMs than the stock rom on my Sprint Galaxy S3. I was running Cyanogenmod 10 release candidate, and it seems to me that the signal was way worse than with the stock rom. I would also be in downtown Seattle, certainly with LTE service, and still I was stuck at 3G. 4G/LTE seems to be a thing of the past with the newer ROMs that I've been enjoying.
At the moment I'm back to a stock ROM, CleanBean v4.2 with Android 4.1.2. It seems to be happier. But I won't be back to an area with normal cell service for quite some time.
An interesting idea that the ROMs were reporting the incorrect signal strength. But reporting 3G vs 4G incorrectly too? That seems like something else was wrong.
I was thinking perhaps it was the radio or something, but CM doesn't really mention anything about flashing specific radios.

Are you judging from actual numbers or the signal bar? The latter is notoriously inaccurate many times (and can vary depending on what rom you're using

As for not jumping on 4g when I should have been, that was my oops. I had the settings in the phone to only do CDMA/3G rather than LTE/CDMA/3G. I would flash the radio to the newest version and leave it at that. I heard from someone else in another thread that the radios don't get changed.

As for the feeling that the signal was reported incorrectly, I learned this. Dirty Unicorns, probably most other modded ROMs as well, are reporting the TRUE data signal strength in the signal bars. I downloaded Signal Check Lite. I compared the signal reported in the ROM to what this program says and they are identical. The bars are reporting the connected network types signal strength (ie. LTE,3G). It also says to be showing the RSSP which has been widely skeptical in most threads. If you're worried about your signal, check that program before switching away from a ROM or going back to stock. I actually kind of like them displaying the good info rather than just voice signal.

Does the kernel being used have any affect on signal reception? I'm just curious because I've switched between a few different 4.3 ROMs and the quality of signal is different between them.
When I was running Slim Bean 4.3, receiving a data signal at work wasnt a big issue. This morning I flashed Liquid Smooth 4.3 and even though the numbers being reported for signal strength are very similar, data on Liquid Smooth is almost unusable. Let me reiterate; Same phone (latest PRL), same location, same radio (MD4), same signal data numbers, using 2 different 4.3 ROMs and getting 2 extremely different usability results.
I'm not blaming either ROM, so I dont want to post in said threads, but is there a reason why this would be happening?

You are using data on the cell network and not the wifi network correct? There is a slight chance that it could but it would be mostly dependent on your modems I think. I am sure the modems and the kernel interact but that is about it. Testing for my issues, I am flashing the stock kernel back in, after doing a nandroid of course.
Disclaimer: I could be speaking rubbish. If I am please feel free to correct me, as I am still trying to learn.

On custom ROMs you run, I think its best to run the kernel that the developer incorporated into the ROM for awhile. Then if you are sure your picking the correct kernel, you can try it out, but not before a nandroid of course. A touchwiz kernel is not going to function correctly on a AOSP ROM. Can cause alot of problems, TW & AOSP kernels are 2 totally different animals.

My battery life is sucking. I am trying to improve it so I thought I might try the stock one.

Too many factors to list can cause this, try a different ROM with a clean wipe. Never use a TW kernel on a AOSP ROM.

[Q] how come suddenly it can't keep a signal after switching sims/services(tmob2aio)

yeah, first thing i accomplished successfully tho not without a lot of wiping an rewiping and installing and reinstalling stuff, was unlocking the phone, then i put in the aio and it did it's thing on it's own and connected wonderfully. first time trying to go back to tmob, it started this misconnection issue. it's basically intermittent closer to non operational, tho i did get a random text tonight from a friend i was unable to respond to, because im like kinda connected for a sec, sometimes i'll see the opposing 4g arrows working in the notification area, but not long enough to get info set in the apn settings, you know where i'm talking about. half of those settings work only when you have a signal, for ex. i do the manual part correctly, hit the save apn button ... nothing saves, nothing happens better after that.
i bet you i need to update that radio huh? just tried to flash a newer rom and it said no because my radio was too old. i could have sworn my stock rom, which is supposed to be the latest... which maybe was old right? its in the threads here, first stock you'll find. probably that rom was cool with the uvle1... confusing stuff. okay, til someone answers otherwise i'm just gonna keep trying to update this radio. i guess it is only good now for unlocking...

okay, so i just flashed jedi mind trick which updated the radio, but the stock rom didn't. so does that mean that some roms will not touch the radio while others will? and what was wrong with the radio before? was it made to work only for the associated older versions of android?
