[Galaxy S III Q&A, Help & Troubleshooting] Diskb0x:
First time flashing a Samsung device, are there any risks involved in the above process i.e. wrong country and secondly, [MENTION=4820940]featherknox[/MENTION] why is a custom recovery required, is there no way to flash a stock rom straight over another stock rom with out it?
[Galaxy S III Q&A, Help & Troubleshooting] thehavoc:
I can confirm that this method works. XEMB5 (4.1.2 stock rom) on top of the crappy 4.3 update, rooted it and then installed CWM. flashed the patch modem from the link he gave and the XEMB5 rom is working with network running again. but it seems like the battery is awful, 95% in just 10 minutes? lost 5 percent for that short amount of time -_-

then again, thanks for this!

Battery Drain

Yes after flashing this modem the battery drains so quickly..

I am looking for any solution. Hopefully any developer would come with a good solution.

In battery system I see The Android System draining almost 25 to 30 percent of battery

My problem is little different. I can flash any ROM via Odin[DO NOT FORGET TO CHARGE YOUR MOBILE ABOVE 80% battery level!]:

1. Goto recovery by pressing "vo upl+home+power" release when you Samsung's bootloader.

2. Do factory reset/wipe everything.

3. Remove battery for 10secs. Then put it back.

4. Now press "vol down+home+power" to bring it into download mode. Then follow odin flashing procedure. It will work for any Samsung rom. No need to intall any custum roms.

Now going to my problems:

A. My s3 shuts down when it's idle.

B. Bluetooth button does not work. It tries to go to ON position but goes back OFF after 2/3 sec.

After downgrading from earlier 4.3 [SWC] I have even upgraded it with latest 4.1.2 xxemh4 but no luck!

Every thing works network, wi-fi etc. except above two problems!

Help me please!!

I FOUND SOMETHING, WHEN I DO *#1234* IT SAYS CSC: UNKNOWN though my network is ok and wi-fi works fine. Lemme try patching CSC as featherknox suggested!

[MENTION=4820940]featherknox[/MENTION], But your patched modem can not be flashed in recovery[stock] mode as it says "Signature verification failed". HELP ME WHAT I SHOULD DO?

[Galaxy S III Q&A, Help & Troubleshooting] ashvincj:
Hello, I had the same issue while going back from 4.3 to neatrom 4.1.2. And I tried everything including what you suggested but still no network. So I flashed the 4.2.2 stock rom and gave it to the repair shop and he was able to repair or fix the EFS folder and the network was back again! But the problem is that now I can't seem to move away from 4.2.2 as any other stock/custom rom I flash I get no network! :crying::crying: And if I come back to 4.2.2 then only it works. Is this because the repaired EFS folder works only with the 4.2.2? I am clueless! :(
[Galaxy S III Q&A, Help & Troubleshooting] boomboomer:

Actually modem did not help me either! So I repartitioned, formatted EFS and everything with "RESCUE FIRMWARE SGSIII I9300" by A.S._id. Now everything is fine. I am doing back and forth between 4.1.2 and 4.3. No problem at all!

Hello, yes I have put the file you suggested to download! And should I include all the 4 MD5 files and the 1 mx.pit file also while flashing? What do I need to tick in the boxes? Thank you! :)
[Galaxy S III Q&A, Help & Troubleshooting] boomboomer:
Follow the instructions from the rescue firmware thread VERY CAREFULLY. Flashing a pit file incorrectly can hard brick your phone.
[Galaxy S III Q&A, Help & Troubleshooting] ashvincj:
So should I flash the PIT file also in order to get my network working? :)
[Galaxy S III Q&A, Help & Troubleshooting] ashvincj:
Did you flash all the files including the PIT file also? thanks and did you tick Re-partition in ODIN?
[Galaxy S III Q&A, Help & Troubleshooting] boomboomer:
Just follow the instructions in the rescue firmware thread, if it says tick a box then tick it.
[Galaxy S III Q&A, Help & Troubleshooting] khaaba:
Hi, sorry. I was busy in some other work. Yes, I did re-partition using the pit provided in that thread! There is a picture attached in that thread which file to put where. Everything is complete in that instruction. JUST FOLLOW IT. Rest would be fine do not worry if your phone model GT-I9300 :)

I already re-partitioned thrice with that rescue software!

Need help

Hi! First time posting here, but i've read and learn A LOT from all you guys.

My problem

I was using CyanogenMod based on 4.3.1 when i downgrade to 4.1.2 then my IMEI change to 0049 (No Calls, No SMS)

Then try many, Many, MANY Roms (4.1.2, 4.2.2, 4.3) and did many backups, restore, delete of my EFS folder. No positive results. I have now some 4.1.2 stock and my EFS folder has a nv_data.bin (2mb) nv_data.bin.md5 (32kb), still no network (No Calls, No SMS), tested many Modems too, same bad results.

I'm really tired after 2 days of search..

My Question

If i flash + RESCUE FIRMWARE SGSIII I9300 + from A.S._id I will get my original EFS folder/modem/network back? or i have to take the phone to a Samsung Service? In my country there is just 2 of those and really far away from me.

Hello, I flashed the Factory XXMEG4 rom and then Flashed my country's FW and still 'Emergency calls only' :( :( I am so depressed. What can I do?
[Galaxy S III Q&A, Help & Troubleshooting] khaaba:
Select all the files after extracting and do exactly as explained in this attached image by A.S._id. After flashing and before installing anything, type *#1234#. Check whether PDA, Modem and CSC are shown. If so, go to setting>More networks>Mobile networks>network operators and then select your network operator. It should work.

After this, you flash your country's FW!

Hi bro's

i had the same issue since the official i9300 JB 4.3 rolled out on Sammobile and i wanted to get back to the stock 4.1.2 badly but then i found that my IMEI number have been changed to 00452xxxx bla bla.....:o

that's why u cant register on Ur network provider which causing no network problem.

so the only solution i found is to patch a new IMEI via a Samsung software box called Z3x and it was a peace of cake solution :D and it cost me a few dollars

anyway u can do a little search on Google to find how to do it but u need that

Z3x box.

but there is a bad news which is.... i have to do the same method every new ROM i flash :(

it seems "as a fellow said" that Samsung wont us to downgrade from that crappy 4.3 update :rolleyes:

i prefer this method coz there is no collateral damage to the phone :D and everything's working great and that's because i noticed "as a lot of members said" that the modem flashing caused a battery draining issue and its really bad one :eek:

First flash again the last working stock 4.3 that u had before to bring ur imei back.

Then Downgrade from 4.3 to 4.1.2. I have done this with 100% Success :)

BACKUP everything. (Important)

Turn ON USB Debugging mode and Unknown sources.

First ROOT your phone.

Open Playstore and Update SuperSU. Open SuperSU and it will give a message to disable KNOX. Click YES/Ok.

Then install Titanium backup root from Playstore. Open it, go to backup/restore tab.

Find,

1.com.sec.enterprise.knox.attestation

2.com.sec.knox.eventsmanager

3.KLMS Agent

4.KNOX

5.Knox Notification Manager

6.KNOX Store

Go to each one of it and Uninstall them.

Next restart your phone.

*VERY IMPORTANT* Now Backup your efs folder by using EFS Professional on you computer (Link: http://d-h.st/Gfo ). Because your imei number will be changed after downgrading. You can easily restore it later.

Now install Mobile Odin Pro from Playstore on your phone. Here is the link.

https://play.google.com/store/apps/details?id=eu.chainfire.mobileodin.pro

*IMPORTANT* DO NOT flash firmware for downgrading with Computer Odin as it will NOT work and it will FAIL. *ONLY Mobile Odin Pro from Playstore will work.

Copy your 4.1.2 firmware to your phone. Next Open Mobile Odin Pro on your phone and let it download some necessary files from internet.

When done, click on Open file and select the firmware. After loading the firmware scroll down and UNCHECK EverRoot(because it cause problems). Then click on FLASH Firmware.

*IMPORTANT* If your phone get stuck on samsung logo. Go into recovery mode by pressing Home+Power+Volume UP keys together for 15 seconds. Click Factory wipe/data and then Wipe Cache. Then Reboot.

Now check your imei by *#06#. If imei is changed then restore it from EFS Professional.

[Galaxy S III Q&A, Help & Troubleshooting] Sudo77:
Good solution, however I think you have a wrong theory. This IS an EFS AND modem issue. When you run 4.3 you are running of new efs v2 UNREADABLE by older modems. When you downgrade, you are downloading the modem as well, and recovering efs v2 will still fell imei. You can easily fix this problem by upgrading to your original modem (what you are doing) on 4.1.2 and it can read efs v2 again.

[G2 Accessories] rfarrah:
For the Verizon model, it's been difficult to get. I pre-ordered mine early in the month. It was supposed to be available 11/5, but there have been nothing but delays from Poetic. SOME people are starting to get them.

I hadn't heard anything from Poetic despite several emails so I called them. A guy said they'd had trouble keeping them in stock and getting enough of the product from the manufacturer. He apologized for the delay, but I felt like he was making excuses for why he hadn't responded to my emails. Doesn't sound like a very big or professional company. He said mine should ship out today and I'd be getting updated tracking info. He said they wouldn't ship it to arrive any faster, despite the delay. Unless the case is simply fantastic, I can't see me ordering from these guys again due to the low quality service and communication.
