[Q] what should i backup before downgrading from 4.3 ? - Galaxy S 4 Q&A, Help & Troubleshooting

i know there are serious problems happening when downgrading from 4.3
it happened to me a week ago on my i9500
i flash MIUI V5 and lost my imei , had to send it to a friend which fixed it in his lab
im not giving up though, i really like and used to MIUI and still want it, the question is how to avoid that from happening again, what did i do wrong ?
and worst case scenario it happens again, what should i backup exactly ?
ive installed andromizer and backed up my EFS , does this backup include both my IMEI and SN ? should i do anything else before trying again ?

I think it's a matter baseband
Stock-based MIUI rom touchwiz 4.2.2
And you are of 4.3,
Already trying to restore a EFS backup?
Note: sorry if im wrong

Baseband=modem?
Anyway i tried flashing miui, couple of versions of it, and ended up with the same results
No outgoing calls when on miui, incoming ok, sms, internet, just no outgoing
Imei and sn are intact, things got back to normal only when i flash stock 4.3 rom
I want miui :-\ what am i doing wrong?

There is no turning back. Install the MI launcher instead or any MIUI theme for launchers.
P.S. I have tried MIUI. Good but not as good as what they say.

thats weird, i ran into some people running 4.2 on their i9500
not MIUI but other versions which worked perfectly
youre telling me im stuck with 4.3 and newer ?
edit :
what about this method
http://forum.xda-developers.com/showthread.php?t=1658809
can i just pull the baseband from the stock rom and flash it on my phone once i have miui ?
would that work ?

No, you're not stuck. I've been using MIUI v5 and stock 4.3 back and forth testing which one is better. Personally, i like the interface of MIUI especially the icons BUT there's so much jitter and random reboots every now and then. Wait for the Kitkat release of MIUI.
Why would you change the baseband? o.o

i get NOT ALLOWED BY SIM error everytime
i can get calls and send sms but no outgoing
which modem are you on when on miui ?

I just flash MIUI and i'm good to go. What carrier are you on?

[Q] Installing PARANOIDANDROID

Hi,
After installing PARANOIDANDROID following this post . The baseband isn't recognised inside PA, so i tried to flash it after the rom but no change. I read a lot about loosing the Partition where the IMEI is stored an got really scare xD After unroot and going back to stock Rom everything is fine. So PA didn't recognise either the partition or the baseband ? Am I doing anything wrong because in no faq was my problem explanded or mentioned.
Sorry for my bad english.
Regards,
Zardorac
nobody ?
You most likely did not do anything wrong, I've been seeing a lot of issues lately with the radio after people flash PA 3.99. I had an issue too last time I installed PA where my radio stopped working completely no matter what the ROM, and I wound up having to use the LG download tool to fix it.

so best option wait for next release or is there any other option.

Dont want to loose wifi again.

I lost my wifi when i was already running a google kitkat rom and tried to update to a newer version of the same rom.
and after endless flashing different roms and wifi fixes i gave up and took it to a phone repair shop..
He tried to do the same thing i was doing and then couldn't get it to work either.
And told me i need to replace the main board $220 later i am now here.
Android 4.22
Baseband 19505XXUMDC
Kernel version
3.4.0-102938
[email protected]# 1
thu jul 4 22:12:38 KST 2013
build number
JDQ39.19505XXUBMG4
the phone doesn't seem to have root and has stock recovery.
putting it into download mode i get official now. before i had knox01
I have read a few post about a few people that have lost there wifi but nobody has been able to explain why this is.
I really would like to put a kitkat rom back on my phone, but my ill never hear the end of it from my wife if i brake my wifi again.
is there a method i should follow to minimize the risk of this happening again.
,
I would say, its ur old baseband.its a 4.2.2 now.
Do you know which one do u had before?
Flash a 4.3 modem with Odin and then i think it will be working
I use a MJ8 baseband on my 9505 and tried alot Kitkat Google Editions ROMs with working Wifi

Why would he flash a 4.3 modem when he has a 4.2.2 firmware mate? Your post doesnt make any sense. Please explain? The op is asking for an opinion without him getting a wifi problem later incase he flash any custom rom/kitkat in a future. And gutterat if you are going to flash any rom do a nandroid backup before you flash anything. IE: EFS and such.

Sorry i edit my post.
When he had a 4.2.2 baseband before too, and tried to flash a Kitkat Google Edition, Wifi won't work with 4.2.2 baseband. U have to upgrade to a higher baseband than 4.2.2 for a working Wifi.

im not a total noob
i have rooted and put custom roms on many of my other devices
Galaxy 1
Galaxy 2
Galaxy 3
Acer A500
Note 10.1
Ouya
this is the first time i have broken something and not been able to fix.
I am unsure if the wifi just crapped out or it was a result of me flashing it.
last time when i lost my wifi i think i had nandroid back up ( made a back up in philz recovery )
when i restored still had no wifi
is this how i achieve a nandroid back up or should i be doing something else ?
was it a knox issue that broke my wifi last time ?
should i look into rooting without changing knox
warranty isn't as issue as i don't have any..
Did you buy a new mb
Didnt you try warranty
Was the repair guy a noob
100's of threads about broken wifi, didnt you try any of them fixes.

advice needed: downgrade from CM11 to 4.1.2

Hi,
i had CM 11 for a while but recently the bugs get worse then less. In the moment i cant make any call for example.
I tried Sammys 4.3, but the experience was very bad too. Pretty buggy, some apps wont work...and slow like hell.
So im thinking of going back to the latest 4.1.2 sammy rom.
I lost a bit the overview about efs and all this stuff.
Is there any problem to expect doing this? What was the latest or best version of 4.1.2?
Thanks
Your EFS folder version can normally be determined by what modem you have installed.
If you have flashed stock 4.3 it would more than likely be EFS v2
I think you should be ok to just flash a stock rom in odin but just let someone confirm this or just have a quick search. If you want to make sure it shows as official in download mode, then use triangle away to sort that

Is that the latest? I dont know dannylow79.
I always had the cwm versions of wanam or Justarch
I think all the latest 4.1.2 had EFS2. What about bootloader. Are there anymore problems to expect?
thanks

These roms are pure stock, i know because i build them. the lite version had all the bloatware taken out.
Ofcourse your are free to choose the ROM you trust. Just take a look in the treads of the ROM of your liking.

loss vibrat in i9500

Hello every one ...I got new problem in my new phone s4 i9500 ..suddenly loss vibrat touch during using the phone in custom rom ...I flash sokp at first custom rom and got that issue then flash hassan rom based on stock at first flash the issue present but flash it again and then work after that flashed aicp rom and after some days today the vibrat gone even in recovery mode ...what can be the problem ? My phone still new 1month ago ..can it be from kernal philiz ?? Thanks for any suggestion
any suggestion or throw my phone from window ......software or hardware problem ?????
Hi Ammar,
I think your problem is in software. If I were you, I install cwm or twrp recovery, do all wipes including system, preload and internal memory, then flash the latest official firmware with Odin. If problem stands still, I do all wipes agaün and install the latest official firmware again. Even if this is does not work then I decide the problem is hardware based.

Well I cant comment on what went wrong.
I was on slim rom once and my vibration Intensity was tooo too low. Because of that was missing calls.
Or you can download an app for checking vibration. Once my proximity sensor and speaker stopped working, i ran a test and everything was back to normal.
Try test you android from the playstore and see if that test works.
Well here is the app
But again as I said, let us know if this is happening on the stock rom.

Once my Wi-Fi stopped working on a Cyanogenmod based rom. I flased stock firmware many times but it didn't work. Then I installed cwm recovery and do all wipes then it worked. As you understand, such wierd things might happen sometimes that we couldn't understand.
i sent my phone to company and told me that vibrate engine is broken and they change it and now work good but what is the problem that caused this i dont know exactly ...as they said either by drop the phone or by water but non of these happend with my new phone
thanks guys for help

[Q] Samsung Note 3 Downgrade from Android 5 to 4.4.4 or stock

Hello
INFO
I've installed the echoe rom version 22 http://echoerom.com/roms/echoefull/note-3/ on my phone ( samsung note 3 [n9005])
(with a the AEL kernel don't know if this is usefull info http://forum.xda-developers.com/galaxy-note-3/development/mods-xxugbnl8-t2986519) )
also I've changed the bootloader to the appropriate Found on the XDA forum http://forum.xda-developers.com/showthread.php?t=2495688
BL_N9005XXUGBNL8_CL3643614_QB3415922_REV00_user_low_ship_MULTI_CERT.tar.md5
I've changed my modem to CP_N9005XXUGBNL8_CL3643614_QB3415922_REV00_user_low_ship_MULTI_CERT.tar.md5 (which was a bad decision no 4g/lte anymore)
I've upgraded my recovery from cwm 6.0.4.6 to cwm 6.0.4.7
I did a back of my imei and efs just in case something would harm it and render my phone useless.
Problem:
Now I'm wondering can i go back to, either Stock 4.4.4 or a custom rom
I want to do this because the Rom is too new and not all apps i want to use, such as xposed framework and many other are unsupported. (which i should have checked before flashing)
Plus I'm not enjoying this rom due to many crashes, such as Unified Daemon (EUR)(needed for weather updates etc) and limited mobile data speeds and many mobile data disconnections, also I notice my Note 3 is running slower while using less ram than before which is very odd..
Many thanks in advance!
P.S.
I have all the files online I've made an online back up of them so which I always do for repairing purposes none of them is altered or tampered with by me.
Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Good luck

Yes u can!!!!flash your stock rom with Odin and everything will be fine!!!
HIT THE THANKS BOTTOM IF I HELP YOU IN ENYWAY!!!!!
I was trying out some lollipop roms and in my stupidity didn't think about not being able to go back to kitkat.
After finding that a few apps I use don't like lollipop i thought I'd revert back, I went into recovery and tried to flash the kitkat rom, but it would keep failing. Panicking I remembered the nandroid backup. I restored my older kitkat rom and all worked well... Phew!
Moral of this story is always backup.
I'm now back on a lollipop rom, (audax) as so far everything is working like clockwork. But I still have my nandroid backup just in case
Lucky you! ;-p i don't have a nandroid ba-up but i do have the stock rom 4.3 somewhere i might try that after my exams are over! Thanks!

Well I haven't tried it but if a nandroid works a clean install via odin or the cmd way should overwrite everything on your device so if you follow a tutorial for restoring your device to stock you should be ok i think BUT I haven't tried it so please ask around some more.
