Hi guys.
Ever since I've upgraded to 4.3, my wife's XTZ performance went away. Everything is choppy, lags a lot and scrolling (in apps like facebook) is a pain the ass.
Can someone please guide me in reverting the firmware back to stock 4.1.2? The tablet is an wifi only, 16GB, unbranded european model.
At this point, we see as solution either reverting to a stable firmware or sell it and get a freaking ipad.
Thank you so much.

It is probably not 4.3 or 4.4.4 that is causing the problems; instead, it is probably the quality and quantity of apps installed on the tablet. Inferior coded and ill behaving apps will cause any version of Android to have poor performance. Perhaps backing up your personal files and then restoring the Android install to factory and reinstalling only necessary apps is what needs to be done. Getting an iPad is something only a brain-dead zombie would do.
Unfortunately, I've done a factory reset and reinstalled all the apps: facebook and Accuweather. Same poor performance.
So, is there a way to downgrade to 4.1.2 please?
Anyone?
Thank you.

it is better to make a clean install of 4.4.4 kitkat instead of 1.5 year old 4.1.2.

Hey guys, I just did an OTA sw update (spanish official 4.1.2 rom, rooted & no other modifications).
Since it didn't contain any useful info other than it's a software upgrade, I'm confused about it. What did they upgrade for me? Was it rom related? I haven't noticed anything different about it so far.
Any info about it is welcome.

That 22 mb update will get you to LSD.
Thanks for the info!
Btw, just found out that the OTA has in fact failed, so I tried doing the upgrade via Kies. It went well, except for the fact the root has been removed by the update and I had to re-root. Also, the CWM I flashed a few days ago was gone too (but I used stock rom to root).
The changes I have seen with this update is only that my kernel now has a new build date (31. jan 2013).
can you post a review or comparison with your old rom (I assume it was LS8),

Well, I can't really post anything useful, since I was looking for "the perfect rom" from the moment 4.1.2 official appeared. Before that, I was on 4.0.4 official. The only real thing I've noticed (between this and all other roms I've tried out) is that I have a bit high battery drains if I keep WiFi turned on while at my office. I've figured it's something about the router itself (never use Apple made routers!), so I "fixed" it by not using WiFi at work.
Sorry for not being more informative, haven't really done any elaborate testing apart from noticing obvious things like battery drains. The only thing I can say for sure is - 4.1.2 >>> 4.0.4 and 4.1.2 official >>> custom roms for me.
I recently tried to downgrade my Galaxy S3 from Jelly Bean 4.1.2 to ICS 4.04 using Odin and a ROM file downloaded from Sammobile.
The installation was succesful and after doing a factory reset and clearing cache the phone booted up ok. It connected to my network provider for several seconds and then disconnected.
After several attempts at this process using different files, I noticed that the IMEI of my phone was no longer correct. At this point I thought I had bricked my phone by somehow corrupting the IMEI.
In an attempt to put it right, I reloaded Jelly Bean 4.1.2 and my phone now works fine again. Please can someone advise what I am doing wrong with this process and why the IMEI gets corrupted as this is obviously why the network rejects my phone when I install ICS.
If you would look here: http://forum.xda-developers.com/galaxy-s3/general/ref-galaxy-s3-modem-radio-collection-t1740061 you will found this link for ICS ROMs: https://www.wuala.com/UpInTheAir/SGS3/Modems/I9300/ICS/?key=n0KVwtIMZPE8 . From here, select CWM folder if you want to flash the modem via recovery, or the Odin one if you want to flash it with Odin. Choone one of the file, download it, and then flash it via the method you want.
QuickQuestion: Why would you wanna use ICS when it has been released 4.3 for our device, and 4.4 it is said to be released in the following weeks (Hope so! ). If you want, you can answer, if not, it'ss not a big problem
Thanks for the reply. Is this the reason my IMEI is corrupted when I flash a PDA from Sammobile? I am new to using Odin etc and followed the instructions on the website.
There are some features I liked in ICS that were removed in Jelly Bean, such as direct access to words in the custom dictionary and the 3 x 4 keypad that was removed in 4.3. I already downgraded from 4.3 to 4.1.2 but wanted to try ICS 4.04. So far I can install it but cannot get a network connection for more than a few seconds.
#EDIT: After further research this problem appears to be an issue with the phone's EFS data. I have now used EFS Professional to back up this important area. What I don't know is can I restore this backed up EFS data to correct the problem I'm having when I downgrade Jelly Bean 4.1.2 to ICS 4.04?

If you have a 16GB s3, u might want to keep JB, 16GB ICS S3 has the possibility for sudden death. But, i too am considering going back to ICS, Jellybean is a joke, it lags way more than ICS does. Trying to force the system to constantly render at 60FPS is hardware demanding and was probably a temporary approach. Its unfortunate that ICS ROMS are no longer available for download. Also, i doubt kitkat would be released for our phone.
My S3 is 16Gb and was originally shipped with Jelly Bean. I watched a Youtube video comparing ICS and Jelly Bean and ICS was faster responding in virtually every test, despite the guy doing it being pro Jelly Bean.
I don't know much about the 'sudden death' problem with ICS on 16Gb models but from what little I've read, I thought this was more of a hardware issue due to defective memory chips and/or main boards?
My S3 updated to Jelly Bean 4.3 last December and I wasn't happy because they had removed the 3x4 Samsung keypad that I like to use. I tried a number of different keypads from Play Store but in the end decided to downgrade to 4.1.2, which went without a hitch.
My attempts to do the same with ICS 4.04 did not go so well and I'm still not sure why the IMEI was corrupted or even more surprising, that it was corrected when I re flashed 4.1.2

Not sure exactly how the sudden death works, i just know it affects 16GB s3 variants. I know the video you are referring to, i watched the exact same one. I think most people got caught up in the hype of JB and forgot how good ICS was.

The Youtube video made me laugh as it was supposed to encourage you to want the Jelly Bean upgrade, when all it did was make me want to run ICS even more! I tried a friend's Galaxy S2 with ICS the other day and it was smoother and faster responding than my S3.
I hope to have another go at getting it working but also I am concerned I probably came close to bricking my handset last time because I do not know enough about the process. This wouldn't be good as I still have another year on my network contract to go.
Do post here if you succeed in downgrading to 4.0.4 as I am also looking for it but it's not working
And best of luck
Unless you have a backup of your efs folder, from before firmware EMG4 then you cannot downgrade.
EFS format was changed at EMG4 to v2, earlier roms are incompatible with v2 and later roms incompatible with v1 so IMEI will be corrupt.

Thanks for the info.
My S3 was shipped with EMG4, so unfortunately I don't have any efs data that I can use with earlier ICS firmwares. I was trying in vain to load BLG8 but it just resulted in a corrupted IMEI and no network.
Unless there is some way of converting saved v2 efs data to the earlier format, then I will have to stick with the Android version I have.
Why are you not trying 4.3 or custom rom mate? My god if your phone is giving u problem u should try to tame it. Very smooth, the nb6 firmware. Or at least let yourself try a custom rom for instance temasek.

I have tried the Official Samsung 4.3 release but didn't like that they removed the 3x4 Samsung Keypad, which I prefer to use. I've tried custom firmwares on my old phone (Galaxy Ace) but never had much success with installing them or getting things to work properly after.
My S3 is still under contract for another year and my skills in this area of modifying are beginner level at best, so I plan to do a lot more reading on here and a lot less messing around with the phone firmware until I know more about it.

Your phone lag is because of Samsung bloatwares, get rid of it and you would be fine. Temporarily suggestions would be hang on 4.12 and try greenify. U don't need root but root would give you he best out of it. Look up cf autoroot and begin your journey.

had installed android 4.3 on s3 but then I installed 4.0.4 after that I had no gsm connectivity see the block sign between battery and wifi. I have gsm connectivity on 4.3 but not on 4.0.4. A guy told me that it has something to do with the bootloader. I wish to install 4.0.4 stock ICS BTU rom if there's a way do tell me. Thanks in anticipation!
Ya i tried this as well because i was really considering downgrading to ICS. IMO it runs way better than jellybean. If anyone knows how to do this, please, enlighten us. For now, just reflash the 4.3 ROM to get your signal back. As i understand it, once you go to 4.3, you need to do a downgrade, you cant just flash the ROM, if anyone can explain the process, that would be great.
For the record, if you have a 16GB S3, i wouldn't recommend the downgrade, the 16GB was subject to a sudden death syndrome and the fix is not included in ICS. If you have 32GB+ then you safe.
I have a 16 GB version of s3 I think then I should go for cyanogen

Flash a modem that's MG4 above, this is asked hundreds of times a day, use the search.

Better still flash a decent 4.3 ROM. Is there a good reason why you want to go back all the way to 4.0.4? Did you skip 4.1.2 altogether? That was better than 4.0.4, but my brief experience of 4.3, after the initial problems with the disastrous MJ9 release were resolved, is that it's the best yet.
Hi,
Is there any way to install Android 4.4.4 without having to root my phone? Seems like every root I have tried have halfway broken camera, but I still want KitKat running on my phone.

No,you cant flash custom roms without root.
Rooting is pretty easy.Just search the forums and you will find one ! GL :good:
@Fyttikatta: here you find instruction and download for rooting. Before, flash the last firmware, also with Odin, and make a factory reset in recovery (to repair the camera item).
Yes, I'm familiar with rooting, but every ROM I have installed have not worked with Snapchat's record function as well as the camera requires rebooting like every 2nd time I open the app. It becomes quite frustrating, therefore I'm looking for a ROM with a "working" camera
If you want the hardware to work perfectly then you'll have to stick to either stock or stock based rom.

Well, if Samsung could get their sh|t together we wouldn't have had to root our phones.
The only time I've been able to send full length videos on Snapchat was with blekota's s5 rom ages ago. I'm on the latest archidroid right now and loving it, I mean the camera has crashed a couple of times and still video recording cuts out but I've learnt to live with it until I uninstall Snapchat which seems to only crash the camera for me

Root is irrelevant to custom rom, they all come rooted. If you want kitkat with native hardware support then buy a newer phone.

So basically what you are saying is that if you have a PC with Windows Vista, you should buy a new one to get Windows 7? At least with Samsung's flagship phones, the Galaxy S series, they should support for OS upgrades more than a year. Even the S4 have Lollipop, why shouln't the S3 have KK?
PC is totally different, no comparison could be made as Microsoft doesn't own or control the hardware. S3 is over three years old and doesn't have enough memory to run 4.4 stock, yes it could run it but Samsung decided not to bother writing a slimmer firmware.

That is still no excuse. KitKat was released only a year after the S3, and I have been running different versions of it on my S3 with better performance than with stock. Still they decided to give the S4 an overhaul with Lollipop two years after it's release.
I can't seem to get a clear answer searching the forums... I've been on stock, unrooted 4.4.2 for a while now and all is working fine. The OTA update (for 5.0) is sitting on my phone and I just keep delaying the install. I've been tempted to get one of the new ANDROID AUTO radios and in order to do so, I'll need to upgrade to Lollipop... But I keep reading about bad experiences with the tmobile 5.0 variant.
Anyone on tmobile stock 5.0 happy? Is everything working? Battery life good? Wifi not dropping?
For that matter, anyone on stock 5.1.1 happy? Does mhl still work?
I'm not super interested in rooting (I will if I have to) or running custom roms (I really need wifi-calling) -- just worried the stock OTA experience is borked.
Any advice appreciated. Thanks.

5.1.1 is noticeably quicker than 5.0 or below, however it has a major MHL bug, i.e. it does not work! Just purchased the MHL adapter (wasn't aware of what I was missing...it's awesome), but had to downgrade to 5.0 in order for it to work. My guess is a 5.1.1 bug fix ota is likely in the works....I hope. Anyway you can freely Odin flash between any firmware version for this device.
Thanks!
Updated to 5.0. Everything seems to be running smoothly... I'll hold off on 5.1.1 for a while until there's a bug fix.
