no simcard inserted

hi guys, ive got a serious problem :) i managed to root and downgrade. the proper menu appears, i do everythnig according to the manual, but the phone keeps claiming that there is no simcard inserted. any ideas?

actually i didnt have to do write the code *#197328640# for second time. have i9350 from uk, locked to EE. i was trying it with the modified fzeta 4.1.1 rom. im going to try the other one...

edit:

didnt work with second rom - same problem. never have to type that code in. i saw some tutorial where a guy just enters into the last choice in the network lock menu - [4] NW Lock NV Data INITIALLIZ and waits for a minute, then restarts phone. I also tried this one with both roms as well, no success at all :( I even tried to do it with or without simcard, but still didnt work...

Problems with S3 I9300 Orange Romania

I tried your way and more than three ways to unlock my phone. Last message from galaxsim unlock was "it's a new locking system and it is not supported yet". If you have any solution please help me. My phone is Galaxy s3 I9300 from Orange Romania.

Thank you!

I'm just going to attempt to flash 4.1.1 as instructed (currently on 4.3) but someone asked the question about whether you can leave your normal simcard in the phone or can you do it without any simcard?

I haven't got an alternate simcard, but don't want to risk my current card getting blocked (as I can use it on another phone if necessary).
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] LucasBass:
HI, this is the I9305, forum, you should have asked it there.

If your phone is unlocked, it will still be, whether you root, upgrade or flash any custom or stock ROM, as I already said in the Original post.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] LucasBass:
To unlock, you should put an alternate SIM inside, don't worry, it won't do anything to it. I'm still using my I9305 with the same sim I used to unlock it a long time ago. you can't use the sim card from the locked carrier. Try to unlock it with this method and post updates whether it worked or not, as I have opinions of different persons, some says it works and some not. I don't know for sure as I can't try it myself now. Anyone who have tried downgrading from 4.3 or 4.4.4 to unlock using this method, PM me or post on the thread please whether it worked or not for you. If it didn't work, kindly explain why also, and the issues you encountered. I will the update the post accordingly.

Downgraded from which firmware?
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] hotlips69:
I just flashed to 4.1.1 using Odin 3.4 (as mentioned in the link at the start of this thread) and on reboot, it gets stuck on the flashing Samsung logo (which I presume is what is called Boot-Loop????)

I then saw the reply (quoted here) about "factory reset from recovery" but it's not obvious exactly how to do that and exactly when?

After the flash had completed, the phone rebooted, it did something on the screen quickly & then rebooted again to the flashing Samsung logo.

1) Should I remove the USB cable & Exit Odin at any point after the flash has completed before/during or after the reboot cycle?

2) If I'm supposed to remove the battery, exactly when?

3) I initially put in a random simcard, but not sure if that is necessary for this flashing purpose?

I've also just seen this comment...is this saying to do something different to what I've quoted in my last post?
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] LucasBass:
To prevent you from being stuck onto the Samsung boot logo, you should wipe cache and wipe data from recovery after flashing the firmware. To do so follow these instructions.

1. Unplug the USB cable.

2. Shut down the phone.

3. Hold down the 'HOME' + 'VOLUME UP' buttons and press the 'POWER' button for about 5 seconds to enter Recovery Mode.

After entering recovery, you should see the options, to wipe cache and wipe data. wipe them. Hope you did a backup as you will use most of you files.

For flashing purpose, it's not necessary to put a sim, you can put one if you want.

Thanks LucasBass and DjemBey. I unlocked my S3 i9305 :)

Unfortunately I had already installed CM on it, but luckily I made a backup of the stock (Orange UK) ROM first, and luckily it was 4.1.1. So I restored it, unlocked, then restored CM and it's still unlocked :)

I think you need to flash a 4.1.1 modem in addition to the main firmware.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] LucasBass:
Correct modem is needed to get Mobile Data etc.. but for the unlock trick I don't think so. A 4.1.1 modem is already flashed when flashing stock firmware. Maybe I wrong though, you can flash one if you want to.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] .NetRolller 3D:
For the unlock trick to work, you need a modem and RIL from a 4.1.1 build - the ServiceMode menus are generated by the modem FW.

It worked for me!

TL;DR

It worked from a 4.3+ ROM-

Download Stock ROM from sammobile (I9305XXALI5_I9305EVRALI5_EVR_.zip)

Flashed with Odin under windows XP

Followed instructions (although had to go in to the service menu a couple of times before it looked like it had worked)

Longer story:

OK so, contrary to the "obselete" link in the first post I can confirm that this method works, as my i9305 was sim-locked to Orange in the UK, but I am now able to use it with other carriers, with no problems.

I was originally on a stock 4.3+ ROM when I got the phone. I Heimdall'ed a CWM recovery, as a first port of call, and then started flashing various custom ROMs, trying to find something slick. Eventually settled on a 5.1 Resurrection Remix ROM before I settled down to try and sim-unlock (I know, I know, weird order to do things in...).

So, needless to say I have the KNOX bootloader (currently showing 1 count for custom binary download and KNOX WARRANTY VOID: 1 - Ho hum...) and I have to say I found it hard work to sort this, but that's probably mostly down to not being confident of data sources, or info sources so thought I'd post in case it helps.

Once I got gold of the 4.1.1 stock ROM (which, try as I might I couldn't get to flash through Heimdall, probably user error) and eventually tried it with Odin from an XP machin, it went on (wiping out my CWM recovery on its way) but allowed me to key in the "code" from the first post and follow the instructions from there .

I had to wait about a minute before the last menu item flicked over indicating it had worked (the SHA256 encryption indicated that it was off after about 30 seconds, but I was in and out of the service menu 2 -3 times by then, unsure of what to expect, and then the last menu item "4" which originally showed as "menu not available" became available then eventually changed to indicate success.

So, thank you to the contributors, you saved me some hassle and cash!

Hope this post helps someone else.

Hi,

Can anyone help me. I moved over from T-mobile to 3 this week. I did not have any spare cash to buy a unlock code for my i9305 so I followed the guide. I could not find a UK T-mobile 4.1.1 FW so I downloaded the UK EE one as EE now own/run T-mobile. I flashed the phone using Odin and it worked fine. I unlocked it all fine. But I have ran into a issue. When I try and update my phone to the latest firmware it says I can't as my phone has been modified and can not update. I have tried formatting the phone and clearing the catch but am still not allowed to update it. Any ideas how I can fix this?

Thanks.
[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] juliancarney:
Hey. I guess you're meaning to update your firmware via OTA. If you had a 4.3+ stock rom previously then you can't use OTAs. This is because the 4.3 stock rom introduced the knox flag, which can not be reversed.

But as there won't be any more OTAs for the I9305 this is not an issue.

Just download the latest rom and install it using Odin, same way as you did with the 4.1.1 (maybe you'll need to reinstall the recovery again before, I use CWM).

There is a 4.4 Samsung stock rom but I suggest you to install cyanogenmod 11 which is 4.4.4 and fully functional, it runs perfect to me with no issues (their web/wiki explains how to install CWM recovery and then CM).

Worked for me on Orange i9305 XXUENG1 (used UK EE 4.1.1 on Sammobile).

1. If it hangs at boot (which it did for me), reboot into recovery and do a factory reset.

2. Strangely enough, I did not "run into the network lock" as stated

3. I did the nw lock nv data initialize anyway

4. Did not have to enter the code again

5. Rebooted and was able to make calls.

WOW!

This thing really works!

I thought I wouldn't be able to do it.

So, here's the story:

I had my S3 I9305 since may 2013. As soon I got it I started installing custom roms on it. It's been crazy theses years. ( BTW, it was unlocked when I bought it).

Last week, weird thing happens. I wake up to it asking me to insert a network unlock code. I definitely got a dafuq face. Especially in the morning :D.

So, thanks to the internet and this amazing community. I found this thread and followed the instructions. After spending time finding the right rom, it got unlocked.

Some technical things though. I recovered my phone to its original firmware 4.1.2. -> tried the instructions and it didn't work. ( I didn't have the #4 option ) Thought it was because I was running 4.1.2.

Thus, spent some time looking for a 4.1.1 rom. Found it and boom! My phone is back and alive!

haha, I will use this phone til there's no more support for it in this community. I hope it lasts at least three more years.

In the end. I have to thank you guys for the instructions you've put on this website.

Thanks! :)

Why getting lock issue repeatedly?

Thanks to [MENTION=5167023]LucasBass[/MENTION] for your tutorial. I took your help to unlock sim card problem on S3 numerous times. My question is, why this lock issue arises with every update I do (fresh, dirty installations) with custom roms? I am currently on cm13 and on RR rom. Since the last 4-5 version updates, I am getting this, then I had to do all the downgrading by several android versions, sim unlocked, then update to the intended version, and soon when there is another version of the rom I use and I try to get it, I need to go through all these hectic job once again, and this continues eternally. I am tired of this thing, I am very very tired now :crying: . Can't there be any other way that would leave the sim unlocked permanently, forever?

I have excactly the same issue. I've been on Custom roms for some time now, and i've been a happy guy. Until some two weeks ago: network locked. Did the whole downgrading thing and re-rooting and re-flashing and it worked. For awhile. Now it's the same all over. I'm on CM 12 based BlissPop.

Sigh, the phone is great and so is the rom, but this locking unlocking thing isn't really a convenience. So any new light on this topic would be apreciated.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
Did you make a backup of your current ROM to before you flashed your ROM?

If yes, what kind of backup? Done with what tool & what was the ROM you backed up?

If not, forget your current root problems, you should start from scratch...

There are various ways to do this & it also depends on what kind of ROM you want to use. No need to flash 4.4 imo unless you want to remain on stock ROM. Unless you have a very good reason for it, I wouldn't recommend to remain on 4.4 when both Android 5.1 & 6.0 are available in unofficial but extremely stable releases.

Here is my suggestion...

If you flashed with Odin to do the unlock procedure, you will have wiped recovery & replaced it with stock.

I suggest you start with flashing Recovery to install the latest TWRP for i9305 with Odin.

Once done, I would now leave Odin & the PC alone.

Now flash a CyanogenMod 13 unofficial release with TWRP as Android 6 is best & there's no need to root as root is actually included in the ROM...

Get either rodman01's Resurrection Remix or pan's latest cm13 unofficial release. They are both very good & stable to be perfect daily drivers.

Important:

Use the instructions given in the OP of each of the release threads to install the ROM zip file properly from TWRP recovery.

Download the recommended Google apps zip for your situation. With cm13, I personally use the nano gapps package. It works well.

Use a usb key or the microsd card to store the zip files & install from there.

[Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help & ] Pe1ican0:
It's up to you of course but imo it's simpler to install & the end result doesn't compare.

Going back to Android 4.4.4 after 2 years on 5.1 & 6.0 would be unthinkable for me...

Of course, if you have to stick to stock, no play with words intended, for selling purposes, it's a different story.

It works both ways I suppose because many potential buyers will prefer Android 6 on their phone than unrooted Stock 4.4.4 with Knox & many more will just love to know that it's possible to have the latest CyanogenMod when they are considering to buy an older phone...

Don't hesitate if you have further queries. ?

Add rebooting to instructions in OP

This worked perfectly for me. Downgraded to the 4.1.1 firmware linked in the OP (originally had KitKat Vodafone IE stock ROM), followed the rest of the instructions and my GT-I9305 was succesfully unlocked.

Installed ResurrectionRemix afterwards and the unlock status persisted.

One suggestion though: could you add restarting the GT-I9305 as a last step? It'll only show as being unlocked if you reboot after following the instructions, otherwise it'll look like nothing happened.
