[Q] Why do we need to downgrade to fix WiFi? - Galaxy S III Q&A, Help & Troubleshooting

Hi
I am going to get red S3 next week and was planning ROMs and kernels.
I have noticed that you need to flash ICS before flashing other JB ROMs, I am no noob to android so be as technical as possible, I absorb knowledge like a sponge.
Also I read that it only applies to people who use WEP WiFi.
This is purely to satisfy my curiosity.
Thanks
P.S does this also apply when switching from stock ROM to one of those customized stock ROMs?

no i am reading pretty new stuff, like slim bean for example, it tells me to flash ics before that so i dont get wifi not working issue

Instructions do not say it must have ICS flashed first
Instructions say if you have wifi issue flash ICS but as i said that was old 2 september post .
Suggest you read the instructions posted for that rom as defined in post one .
From another JB or ICS Rom to SlimBean
Download device_x.x.zip, slim_gapps.zip.
Enter CWM, wipe data, format system ( in mounts and storage)
Flash Device_x.x.zip***, then MUST flash slim_gapps.zip (other files optional)
*** - If the flash is too quick ( < 5 seconds or so), reflash device before flashing common or other zip files

BT Bug? Same procedure as WIFI?
Hy guys ....
first of all ... slimrom 4.2.1 is TOP! really nice ...
but there is one thing i found on my i9300
my bluetooth connection to my bt-keyboard stays only 1 or 2 seconds till its disconnect ...
so my question: is there any other here with same problems? should i proceed like the wifi fix ( stock ics => wifi connect => reinstall ... ) ?
thx & greets from austria
mories
update: i came from slimrom 3.1 but flashed other 4.2.1 roms for testing but made superwipe before installing slimrom 4.2.1 RC1

Everybody's needs & wants are different. So are likes/dislikes/expectations etc.
So if marcopolo says that he needs dualboot, I guess somebody knowledgeable on the matter needs to advise about the possibility and ways of going about it. Not push him to try a new ROM (MIUI 1.10.8 Basic, since thread # 1295089 is for it), or did bimmerrob paste the wrong URL.
I myself have tried a few ROMS - WB TW (before SE released official 2.3.3 ROM), CM7 ZMOD, FXP 028/030 & some other flavors, but I always keep coming back to Stock or it's derivatives due to one issue or another (WLOD's & restarts mostly).
I would also love to have dualboot & would try searching more on it. Will post my search results later. I've dual booted between different Windows versions & linux on my desktop & laptop for years, so why not dual boot (between ROM's) on phone.
I may be from the minority who sometimes face crippling problems with custom ROM's (since most of the users run custom ROM's without much issues). At those times, flashing another stable/stock ROM is not possible due to various reasons (not having access to laptop etc), so temporarily, switching to another stable/stock ROM would be a nice feature to have.
Dualbooting is conceptually possible and we have even tried and tested it with 2.2 ROM's combining 2.1 ROM's
so far no one tried this on 2.3.3 roms.. ITs just a matter of trying and getting it to work.

I'm on the same page as you. I'd like to test a few things out while still having one ROM that I KNOW works as the primary and boot a test ROM to see if it would even work for me.
Been meaning to research and play with the old method and modify it a bit to get this idea working but never have the time.
I'll be a guinea pig for whoever gets this in alpha.
I personally need dual boot to avoid the hassle of backing up and restoring data/apps everytime i try a custom ROM
its annoying when u are not satisfied with the new one and has to switch back to an old one
so............ guys in the ur group as well !!!

Need Help - ODIN flash not happening

well i tried to flash one of those i500 roms on my fascinate just for the heck of it ( i think it was for an Indian cdma operator for I500)
it was a fascinate Rom alright , didnt like it ED05 EH18
but since then i am not able to odin anything , either it stops at recovery or some other point, but mostly at recovery .
i can access the download mode , but odin flashing isnt possible now, no matter which STOCK rom i use they arent getting thru , always get stuck at this or that point.
plz help
regards
are you familiar with ADB? you can push a stock image file that way... cayanogen website has a great tutorial on it.
TBH I am not familiar with adb at all .
but the issue was resolved , looks like my usb cable was the culprit and man !! i wasted the whole night trying to figure that out ( and LOL that too was suggested by wife )
yeah i know
btw DS , could u temme which is the better ICS build and kernel now
this all happened with me getting bored og GB
actually i thought of flashing TEAMHACKSUNG's latest ICS build , somehow when i was transferring it to sd card , nothing was happening so i forcefully removed the cable and tried a few times , but it failed , In the end managed to transfer it via WIN 7 ( previously was using XP )
but when i flashed it via CWM , following proper procedure it failed , i donno what was that and my ordeal started .
and now XP wont recognise the phone neither in ODIN nor in mass storage , so doing it all via win 7
appreciate the help.
regards
The latest THS (7.1) has a few bugs still since it is new. I have been running 6.5 for well over a month with no problems. I don't have any experience with AOKP, but there are many people who choose it over THS. I don't think you can go wrong with either one.

Ths is like vanilla, and aokp is like...... Well it has more ability to customize than about any rom i have seen.
Sent from my SCH-I500 using xda premium
Aokp 28 w/ glitch 14 b6 is the best combination of rom/kernel I have ever used...no reboots, no lag, no sod's, good battery life, and customization like you cant imagine.
Thats great !!
have some specific suggestions or advise ? coz i have never ever flashed any NON TOUCHWIZ ROM till date
or may be outline the process in short , ( btw awesome guide you hav got in general )

[Q] P7510 on ICS 4.0.4 (XWLP5): unstable WiFi

Dear all,
I noticed that my P7510 running on ICS 4.0.4 (XWLP5) has an unstable WiFi connection when the received WiFi signal strength is not maximum (2 or 3 out of 4 bars). Connection often disappears and when trying to reconnect to the WiFi network manually, the there is no response. Turning off / on Wifi on my Tab is no solution to the problem either. Even a full reboot does not always help. I updated from HC 3.2 to ICS 4.0.4. after full flasing HC 3.2 first.
Is this a known issue? I cannot find any decent info on this. Or is there a ROM that fixes this? Please help. Thanks in advance.
I had no problem with the WiFi what so ever not with 4.04 and not with cm 10 jelly bean
Did you have that problem on 3.2?
Try and flash the official ICS from sammobile with odin
Thankfor replying. I did not have this issue HC 3.2. I went back to stock HC3.2 and updated via WiFi to official ICS v4.0.4. No official releases for my country for P7510 are available for my Tab, but other official ICS v4.0.4 versions I tried from Sammobile have same issue.
I'm thinking to go to CM 10 release, but since wiping is required and my P7510 has brick bug, I'm hesitating to do this operation.
Try the sammobile UK version that's what iam running and it had no problems
Cm10 is faster than official ics and gives u much more options It's a better experience at least for me except for a bug or tow but some people don't even notice them
About the brick bug I don't know what that is cause I had no problems wiping data so i can't help u their sorry

I already tried UK version from Sammobile, same WiFi issue when signal strength is not maximum. Regarding the brick bug: check this out: http://forum.xda-developers.com/showthread.php?t=1879941

I don't know what it's not working for you every thing oky with me
About the brick bug....... I just checked and as it turned out I too have the brick bug and I have actually ran EXPERIMENTAL-p4.zip
I have wiped the data and installed custom roms more than I can count......i don't know maybe it's over-rated or iam just lucky!!
Iam afraid to do it again now but he says here "Avoiding brick:
The only danger now seems to bi if you are on stock ICS ROM and you execute factory/data reset in Samsung recovery.
If you are using custom ROMs and CWM you should be safe because all custom ROMs/krenels have now removed mmc_cap_erase() from list of capabilities."
Iam running a custom rom so I don't know.....

what do you suggest ?? I am on ICS

hey all
its been a while
well long story short i am on ICS on my XT912 vzn ,
using it as gsm phone outside country at this time.
having safestrap and got a few rom slots ,
want to get afresh look
can anyone plz link me to a ics kernel based JB rom which is totally debloated and optimized for better battery life
At this time i am losing 1 to 1.5% battery while sitting idle , without anything running
would appreciate some help
even if it means moving to JB altogether , plz guide me regarding that as well.
thanks
AW: what do you suggest ?? I am on ICS
For ICS based Roms (XT912) have an look here
http://www.droidrzr.com/index.php?/topic/1171-Look-Here-For-All-Available-Roms#entry21091
Also you should have an look @ the Dev section of Droidrzr, there you'll find the Dualboot Method for ICS <>JB without apply the whole OTA. On that way you can always flash back to ICS and you'll be able to use all Roms in the List.
An best Rom is related to your needs. You'll have to find it by Crackflashing your Device or read the Threads.

[Q] how/what should I upgrade from my current setup Siyah4.1/ICS4.0.3

Hi,
I have been trying to look for answers in the forum but it is too confusing...My status is like this: I got the phone and installed Siyha 4, that was many months ago, if I look in About this is what I see;
- Android version: 4.0.3
- Baseband v: I9100BGLP2
- kernel v: [email protected]))
- Build number: IML74K.BGLP8
It is working, but it's showing random hangs, GPS does not work many times...and as I see there is even official support for JB, I would like to upgrade. But, I dont know what steps and even what I should upgrade. Not sure if Siyah I can just upgrade without issues, if then I can install any rom I want of top of it...etc. I would be really gratefull if somebody could tell me:
- what I need to upgrade
- in what order
then I will investigate and manage to do it myself. For example, I am after instructions like this (making them up as an example, no idea if this is correct):
1. upgrade to SiyahKernel S2-v6.0beta5
2. restart
3. install ROM cm-10.1.3-i9100.zip
I know there is no 'best' rom, just asking for advise for any JB (or later if there is stable one) rom that works well (no random crashes frquently, GPS working, I really need that).
thanks in advance!

1-to flash stock roms(tar extension) use odin or to flash custom roms (zip extention)then you need a custom recovery (eg ClockWorkMod).
2-if GPS is really matters to you,then dont flash cm10.1 is it have a known issue (gps is not working 99% of all time)see known issues for cm10.1:
http://wiki.cyanogenmod.org/w/Known_Issues_page_for_i9100
if you want stock rom(eg 4.1.2) look here:
http://forum.xda-developers.com/showthread.php?t=1544487"
if you want custom rom with working gps use(in my opinion)neatrom lite:
http://forum.xda-developers.com/showthread.php?t=1569686
guide to flash with odin:
http://forum.xda-developers.com/showthread.php?t=1671969
always check the roms with md5sum check.
Hope it helps.
thanks!
OK, so let's say I'll go with stock rom (I'll remove most of samsung crap with RootDelete)...What about Siyah kernel I installed:
- is it replaced when installing stock rom?
- if not, can I update it to latest Siyah version? should I?

yes,because every rom has a kernel,but if you want Siyah kernel,after flashing the stock rom flash Siyah kernel again.if you want to update to stock jelly bean 4.1.2 then flash latest Siyah kernel.
Sorry for bad english.
