ICS back to GB Question - T-Mobile Samsung Galaxy S II SGH-T989

I am on the ICS Darkside Evolution Beta 1 Rom by TDJ and would like to go back to a GB rom. Is there a way to go back to GB without any issues?? Can i just flash a GB rom and be fine after that? And is the UVLC8 ICS radio compatible with GB roms?? Reason i ask is because im getting better reception with that radio so i would like to keep it but i don't want to brick my phone or anything if i flash back to GB. Any information would help and would be seriously appreciated it. And the reason i would like to go back to GB is because most of the APPs aren't ICS ready so i would just like to wait it out and GB roms are obviously more stable at this point in time.

It's a shame you will prob get flamed for this thread, but I too was looking for the same information. I just spent 20min trying to sort through the 10+ pages of google results and I can say 8 out of 10 simply said "Search". The others where not very clear as to provide an understanding of what was changed when going to ICS, and what needs to be changed to go back to GB.
I am looking forward to an answer by someone with patience for people trying to learn. I dont know about the rest, but I am not looking for a n00b guide, just a better understanding of what needs to be done.
FYI: I have not flashed to ICS yet.

Yes if your flashing its the same process darkside wipe. Install rom . Let it sit for 10 minutes reboot. You can just nandroid as well. Yes the newest radio is compatible with gingerbread roms. I'm using it right now on juggernaut.

So I guess the radio is compatible with CM7 too right?

CM7 is Gingerbread, so yeah!

How was the performance of the stock radio on GB versus what you have tried with the ICS ROMs? Is the signal strength consistent on the old and new radio and ROMs? Is the data faster on the old or new radio and ROMs?
I ask, because I have a HTC Amaze, and am considering moving to a Samsung Galaxy SII, and when moving to the T-Mobile ICS leak on the Amaze, the reception was far inferior for me, than the stock GB ROM and radio.

[SOLVED] ROM or Radio first?

Hi there.
Erm.. this is kinda weird question, say that the ROM that you wish you flash requires a different radio from your current one, will you actually flash the new radio first then only the ROM?
Or you will flash ROM then only radio. Will there be any impact?
ROM first.
9 times in 10 it won't make any difference but there's a chance a ROM might replace the radio anyway.
Thanks Mr_JMM!
I think it doesn't matter..You only need to match your libhtc-ril and radio....

Yes, ROM first.
Mods: This thread can be marked solved and closed now I think.
However....
SOME ROMs when going from certain radio's to certain radio's have had reports that it is better to flash the radio before the ROM.
This seems to have cropped up with the latest GB Sense ROM's.
So I take it back, as a rule of thumb, flash ROM first, I still stand by that, however, check with the ROM first but be aware such things are usually buried deep in a thread and maybe something that gets fixed with later updated versions of that ROM.
Again. ROM first but when a brand new ROM comes out, specifically the new GB Sense ROM's, check the first 5-10 pages.
At time of post, LeeDroid's ROM v3.0.0 is one such ROM that might work better with Radio flashed first.
My apologies but this info is very very recent.
OK, that could make sense. Thought I stepped in deep doo-doo earlier, but rocked back to life with the nan backup. Scared me all to hell, but I might try flashing the radio, then LeeDroid. When coming from CM7 rc3 - It froze on boot.
I did radio first them ROM and had no issues.

[Q] whats the best rom!!!

hello forum, well i just bought a new epic 4g for my sister the phone is rooted, but the rom that this guy flash aint working as suppose "Alpha Hawk w/EG22+" thats the name of the rom, so whats other rom u guys think is better, oh n pls tell me if i can just flash it over that rom!!! thanks alot guys
I don't want to sound like a **** but please search. You are our 30th customer for this question this month. They are all good. If it is for someone else put on ReRFS or EC05plus and walk away.

Most say syndicate rom frozen 1.2, no you can't flash it right over that rom but there's a video showing you how to flash it in the thread. You should teach her how to do some of these things herself so she won't run to you and blame you for any problems.
I don't think there's one best rom out there, since most of it was custom-made, and it really depends on your phone too.. (and i guess different phone gives different result)
but if you want an EC05, I would say the ACS Frozen ROM is probably the most stable EC05 ROM out there..
GB-leak custom ROM is not as stable as Froyo, IMHO..

[Q] Flashing a Skyrocket ROM ( no kernal or radio ) on Tmobile phone does it work ?

Not sure if anyone tried this ..
take a skyrocket ICS build use one of the TMO kernals .. will that work ?
Do i need to flash radio later ?
Thanks
afaik gingerbread kernels don't work for ICS roms, not to mention none of the ICS builds for the SR are stable enough to be used as a DD anyway. Though you can flash them with the SR kernel, you just won't have proper rotation just turn off auto rotation though and no issues.
How about Gingerbread roms on Skyrocket on TMO
Thanks ...
Ok So we dont have ICS kernel ...
Since it looks in TMO we have choice betw slick mod and jaugg ( love rom control ) and Darkside .. only
I was thinking if i put a SKyrocket build on the phone .. will the radio get flashed as well ? any adverse affect that way ?
Thanks Again for a quick response
I've never had to flash the radio, whatever baseband that is on your phone now should be there after the flash. There is however a radio thread in the development section if you wanted to try a different one. There should be no negative effects to flashing a different radio (I have yet to encounter one anyway) so find the one that works best for you. Also, if you wanted to try a good rom, Master&Slave makes a couple of deadly ones. Paradox and Tuesday are the names and they are ridiculously smooth, I just had to use setcpu to turn the clocks down a bit though i'm not sure if it was an error i made or if M&S has them cranked to begin with.
With all the ICS leaked roms popping up, what are you guys using for modem / radio? Do those ICS roms run correctly with tmobile GB modems / radios or are you using the ATT modem? if you are using the att modem.. do you still get hspa hspa+?

[Q] redruM and Jellybeans!

Hey Guys, I had upgraded to the official Jellybean and then yesterday finally rooted my phone. I wanted to flash the redruM ROM onto my phone...long story short after the Flash through Mobile ODIN my phone did what I can only assume is soft brick, but I found another thread with a stock rom and was able to restore the phone back to ICS now running the redruM rom. My question is can redruM work with JellyBean or at least a Jellybean ROM or do I have to pick one or the other? I saw another developer that listed like 5 different ROMS he had installed...can you have more than one rom? I searched and couldn't find and answer for these questions...any advice is welcom because I loved several features of JellyBean that I lost in reverting to ICS with redruM.
Thanks
Jeremy

Probably bc it's a sprint Rom.....

you linked a sprint rom, you need to be a alot more careful flashing things. You can not have 5 different roms. This is the Redrum JB rom http://forum.xda-developers.com/showthread.php?t=1750270 and can not stress enough, read more.

Huh then I wonder if I just put the wrong link...because the ROM worked great once I recovered the phone back to stock with boot-stock-tmobile-sgh-t999 through desktop ODIN...when the phone rebooted...jellybean was gone and the redrum ROM was working just fine with the phone being moved back to ICS 4.0.4....
Regardless the crisis was averted and I've since moved over to Wicked Sensations JB and was even able to backup the "Awesome Beats" program from the redruM ROM and now have it running with wicked....so I'm happy!
Now if I could just get rid of the screen burn that was on the phone when I bought it that I didn't notice!
Thanks for your advice guys...
What you wrote makes no sense, but...
Why are you over on the Sprint forums flashing roms to your phone when you clearly have little knowledge on what you're doing, lol? If you have any questions PM me or someone who seems knowledgeable enough to help you. I fear your phones life.

Not sure what didn't make sense to you...
I was able to get my soft bricked phone into download mode and was able to flash a stock rom from ODIN on my desktop and when the phone booted back up the build was 4.0.4 and was successfully running the redrum rom that originally caused the problem...
Like I said...I probably posted the wrong link to the Sprint ROM as I just did a search for the redrum rom and picked the first one that came up...so my bad I probably posted the wrong link...
Once jellybean was gone after the flash back to stock redrum worked fine...and based on what I'm gathering from you guys is a Sprint ROM won't work on t-mobile phone...well what I'm telling you is that it worked fine after Jellybean was gone...there was a problem with the redrum rom and Jellybean.
But none of that matters..my phone is fine and running a great ROM that I am thoroughly enjoying.
Hope that clears it up...

Running AOSP kernels

Hi guys,
I'm running stock 4.1.2 Jelly Bean on my d2tmo Galaxy S3. When I look up kernels and whatnot, they are labelled many different ways. Some have JB in the name, some with AOSP in the name. I'm wondering: what types of kernels can I flash if I'm running a rooted stock ROM? I don't want to flash any custom ROMs because I'm a musichead and I like the stock music player
Thank you!
First of all you can get then stock music player with a custom rom
Second you can only run aosp kernels with an aosp rom. Aosp stands for android open source project. Aosp is not stock.
You can only use kernels labeled stock or touchwiz if you are using stock based rom
Sent from my SGH-T999 using Tapatalk 2
3rd of all, what in the heck do you want? Haha, you say you are running a 4.1.2 rom (only aosp available on TMO) so AOSP... but you want a kernel for stock (4.1.1) touchwiz rom? The stock music apk is great and works on all stock touchwiz based roms, and in my resource guide I have a huge list of what is available and what is what, if the kernel says 4.1.1 TouchWiz then it is for 4.1.1 TouchWiz. if it says 4.2 AOSP it is for 4.2 AOSP, if it says 4.1 AOSP then it is for 4.1 AOSP... Look in my resource bible in my signature, or in the dev sections for [kernel].
See, that's where I get confused. Sorry for the noob questions. I've been looking around but can't find clear, precise answers.
I'm running the stock TouchWiz, out of the box, 4.1.1 Jelly Bean (updated while not rooted to 4.1.2). That stock ROM is not the same as an AOSP ROM or an AOKP ROM, is it? I have another Android device that runs CM10.1 so I know a bit here and a bit there about ROMs and whatnot, but I'm not so confident when it comes to my S3.
Simply put, I want to keep that stock ROM, but get a custom kernel, because the stock kernel SUCKS. I need to know what kernels I can flash, and clninja already said I can only flash kernels labelled stock or TW. Am I correct, so far?
Thank you!
Well here's a Kernel that is supposed to be supported for STOCK rooted : http://forum.xda-developers.com/showthread.php?t=1785466 :highfive: But seriously you should get a custom ROM, the performance improvement is incredible and power management too ! :laugh:
There is a 4.1.2 stock ota ROM?!? I suck lol.

That ROM is labelled Jelly Bean in the title but underneath that it says it's only compatible with ICS. Question mark.
Question: when you're running a custom ROM, if there's an update for it, say from 1.0.0 to 1.0.1, you can just flash the update right over and not worry about problems right? Or do you need to factory reset through recovery and wipe the caches all over again?

There are a couple of touchwiz kernal's around, Ktoonsez is one that I would recommend, http://forum.xda-developers.com/showthread.php?t=1871946
Usually the general rule of thumb with upgrading custom rom is full wipe and flash, but some users has dirty flashed and had no problems so it depends whether your phone likes you or not.

Most of the times when you flash a ROM that is built off itself, you can "dirty flash". Example--> That means if you are already on a RootBox Nightly 2/17 with a clean install and RootBox 3/6 comes out, all you have to do is wipe /cache and /dalvik-cache and then flash the new version of the ROM. If any bugs creep up, then if you dirty flashed, chances are that is why.
If you are going to go from a TWiz ROM to an AOSP/AOKP ROM then I suggest a full factory reset and wipe accordingly. That way you have a clean install.
Read the OPs of the ROMs

Yup. Thankfully my phone likes me, plus I kind of know what I am doing with regards to diagnosis.
@OP Can you please post exactly what your Build Number says in Settings>About Phone?

You could install the update, but seriously I never do updates. I manual flash the whole new ROM. ( and I never had any accidents or bugs)
For the kernel, its was a example kernel chose the one you prefert ( THAT SUPPORT TOUCHWIZ STOCK ROM ) or just flash a new ROM with build-in kernel like the ParanoidKANGdroid 10.2 ROM !
I flashed the FrostyJellybean ROM with Xone kernel and it's been good so far. I'm a religious person when it comes to battery, but so far it's about the same as the normal drainage on the stock ROM, no noticeable improvements.
Another question (whoop): if I run a Nandroid backup, does that backup include the ROM itself? In other words, if I'm running the Frosty ROM, and there's a ROM I want to test, will creating a Nandroid include the Frosty, or will it just backup the system image excluding the ROM itself? I'm asking this because I have wanted to restore my Nandroids but didn't know if that backup may overwrite my existing ROM with the previous ROM.
Thank you guys for taking your time to help me out, I really appreciate it!

I have flashed a new ROM, so I no longer have the stock Build Number. It now says FrostyJellybean v11.6. I can tell you for a fact that I was previously running 4.1.1 rooted but without any customization or mod whatsoever outside the phone's original settings, so as stock as you can get.
A Nandroid is essentially a snapshot of your ROM at that point in time. You can back it up, try a new ROM and if you don't like it, then restore your Nandroid. A Nandroid should be done before you flash anything. You don't necessarily have to keep them all except your latest, but at least have one for when you try something out.
You can flash and restore just fine from ROM to ROM. Only thing is, you can't restore across platforms. Meaning, if you are on JB 4.1.1, you couldn't restore to ICS 4.0.4. Likewise you can restore a JB 4.1.1 if you are on a JB 4.2.2 ROM because of the file structure. There are ways to do it, but I won't go into that right now. Moral of that story is you can flash and restore laterally as far as builds go, but you cannot restore across different base builds.
*************
I just wanted to see your Settings>About Phone>Build Number because in your OP, you stated that you were running "stock 4.1.2 Jelly Bean". We don't have a stock 4.1.2 ROM, so I was making sure you didn't have another phone. Sure, could be a T999 but there are Canadian versions out there that require different things.
Oh, about the Android version, yes, it's 4.1.1. I wrote 4.1.2 because I thought there was some stuff going on, like wireless and whatnot, and had previously read somewhere that 4.1.2 was rolling out and my phone was doing the "Android is upgrading" thing when it booted up and I didn't check the version before writing that. No worries, it was the stock 4.1.1.
Thank you so much for answering my questions, you guys are awesome!
