[Solved] Boot loop after installing wrong radio. (s3 i9300 international) - Galaxy S III Q&A, Help & Troubleshooting

Hello all. After trying to get various Custom ROMs working, CM 11, 13 or Slimkat 9, unofficial 9.1, no version worked properly with phone signal.. I ended up experimenting with flashing modems or going back to stock firmware and doing all the steps from there but still couldn't make it work.
Stock firmware that came with the phone 4.1.2 (KIES_HOME_I9300XXEMG4_I9300OXAEMG4_1314436_REV00_user_low_ship) was perfectly fine also (I9300XXUGPE1_I9300AMNGPF1_I9300BVUGNB2_HOME) which it's 4.3 from orange spain was fine, tried one from my country and ran fine, also 4.3. Then I found out about this thread:
https://forum.xda-developers.com/galaxy-s3/help/guide-emergency-calls-problem-siii-i9300-t2752541 and by mistake I flashed first the patched modem following this order of events :
4.1.2 STOCK > 4.3 Movistar STOCK > Slimkat Unofficial 9.1 latest > all fine but no signal. Then:
4.1.2 STOCK > 4.3 Movistar STOCK > Slimkat Unofficial 9.1 latest > flashed patched modem from thread above, boot loop.
Then tried to flash the original stock from the phone, didn't work. Stock from my country doesn't work. Stock from spain doesn't work but it goes a bit further in the first boot going to android updating apps , it finishes updating apps and goes into boot loop. That's it. At the moment I can flash with odin or go into downloading mode. When the phone is off, it can manage to charge the battery without problem.
How should i proceed now?
Thank you, I hope you can help or advice me.
EDIT 1: I also tried to flash the firmware from the above thread, the i9300 UK (BTU) but no luck.

Odin can't flash a stock ROM or you can flash a stock ROM but the ROM doesn't boot all the way?

Hey again audit13. It can flash the ROM fine but it gets stuck in boot loop. I'm trying to find the stock ROM with the 3 files but no luck yet, im hoping that can get to do a proper reset factory of everything.

Are you flashing the latest stock ROM from sammobile.com? This file would have everything in one file.

This one ?
Code:
Date
2016-08-01
Country/Carrier
Spain (Orange)
Version
4.3
PDA
I9300XXUGPE1
CSC
I9300AMNGPF1
This one gets to passed the first time the loop till android updating apps dialogue, then goes to boot loop.

Are you performing a factory wipe using stock recovery before booting the flashed stock ROM for the first time?

Wiped, then did a reboot in the default recovery mode. All went to normal again. I still need to figure out how to get a Custom ROM without screwing up everything again.. Thanks for your quick support.

Glad you got it working. One thing I would not recommend is flashing a patched modem. The stock modem is the best modem in my opinion.

Mega...semi-bricked??

So I have a Sprint Galaxy Mega and it seems as though it may be semi-bricked. It will not boot past the GALAXY MEGA logo. It will just continuously power cycle to and from that logo. If I attempt to put it in recovery, it will say "RECOVERY BOOTING" in blue letters as usual, then power cycle right back to the GALAXY MEGA screen. It will boot into Odin mode and accept Odin files, but after attempting do do a typical "stock Odin" scenario, nothing has changed. I looked around for the Pit but cannot seem to find it. Does anyone has a reliable link to the latest Odin stock restore and the PIT file that matches it?
Maybe an error with your system data. So you can't reboot into recovery ? If you can try to wipe data and cache and reboot.
It may be an abnormal re-partition when flashing stock rock, and then I can't help you (have the i9205 international model). Some members of this section have the Sprint version, try to send them a PM if nobody can help you
Nope, no recovery. I was considering flashing a custom recovery to it to see what it does but I don't wanna kill the phone any more than it already is...
Yes I understand. But flashing custom recovery can solve your problem, only if you can boot on it. I think it can't make more damages to your phone, he just always stuck on boot phase like a brick, but if you don't want to try, wait for a developer making you a PIT file. More safe, the Galaxy Mega have a too poor development support for risk anything...
Well I went ahead and flashed TWRP to it. It will boot into TWRP just fine. Tried flashing the stock L900 ROM zip and it still won't boot.
Well I installed a custom ROM, SlimKat, and the phone boots. If I install the stock ROM located in the following link, OP's signature, the phone goes right back to bootlooping. ???
I need either the stock ROM or a ROM with dialer codes because this phone will be flashed to a regional carrier.
what recovry version you use bro. maybe recovery problem. try use your custom rom to flash another recovery from philz. the latest one. some time recovery dont work properly to downgrade from 4.4.2 to stock 4.2.2.
Great, so with Philz Touch Recovery, I never had problems for downgrade and I do this often for testing roms. Now it should not bootloop if you reflash stock.
I am using "CWM-based recovery 6.0.4.7"
I will try Philz recovery
After trying Philz recovery to flash the stock file I found, it once again bootlooped. Is there another stock ROM floating around somewhere or possibly a custom ROM that has dialer codes such as ##3282# enabled?
No idea... But actually the most complete stock based custom rom is MegaFire I think. Flash V5 (not V5x !) it should be enabled.
I don't see what is the problem while flashing stock rom... Oh ! Maybe you haven't enabled USB Debugging, I forgot to do that one time and I had some issues, in case you try to flash a firmware where Knox or others features are on with a modem without these, may cause bootloop. I've searched for 2 days before solve that little problem...
Have you tried another firmware ? If you can flash custom rom, something went wrong before flash... Odin folder is complete ?
Strange...once again a boot loop after flashing the MegaFire ROM
I'm almost certain I need the PIT file. I cannot find it anywhere.
Well I got the phone to boot from that rooted stock ROM FINALLY. I don't remember for sure but I think what I did was first flash TWRP, then flashed boot.img.tar that I found somewhere, it was listed for the Sprint Mega. I then booted into TWRP and flashed the stock rooted ROM(zip) I mentioned before. It now boots perfectly and everything works except one tiny little detail. No WiFi, no cellular signal at all. Baseband version: unknown in About phone.Already tried flashing the Sprint stock modem from the same download link as the ROM and it didn't work.
I'm having the same problem too dude, I
I download n flash all.the firmware I could find online, since I have no idea what the country of origin is. But most of them work, but no WiFi, Bluetoothand the sim card slot don't read

Bricked?? Stuck at samsung logo screen for 1 sec then reboots.

Okay, So the title pretty much says it all. I am stuck at the Samsung boot logo (not bootanimation) and it only shows for about 1 second then reboots and continues.
This started after I tried to flash a rom and it messed up and I tried to flash via odin. I was on MJ9 and and got a bootloop so I did the odin thing. I've used odin before but it is not working well for me now.
I am able to boot into download mode but TWRP no longer works. I was able to flash via odin and it says success but the phone does not reboot like it should.
I have purchased a galaxy nexus on the cheap to hold me over until the nexus 6 is out but if I can fix my note, I would like to.
I know there were other threads about this same issue but it seems that they are all on a different version of the note, or on a s3 or something. Not to mention, I don't see anything that I could try without asking for some help on here. Can someone maybe point me in the direction of the factory firmware (preferably a rootable or already rooted version) that I can flash that will play well with my note.
Thanks guys!!!

Before you tried to flash a custom ROM and things went wonky...were you on Verizon's factory stock 4.3 MJ9 firmware, or on Beanstown106’s modified 4.3 MJ9 with TWRP installed?
Does the phone still boot into stock recovery? If so, you may be able to fix the phone by doing a factory reset.

If you were on Verizon's factory stock 4.3 MJ9, then you won't be able to Odin flash back to 4.1.2 or any earlier Android version because the bootloader has been locked down tight on 4.3 (and 4.4.2) with no current do it yourself method to unlock for those newer versions. You would want to restore the phone back to factory stock 4.3 though, if that's what version you were on before your phone got messed up. You can root the phone on 4.3 with saferoot, then use safestrap recovery to flash some custom Touchwiz ROM's.
If you were on the 4.1.2 based bootloader, (but running Beanstown106’s MJ9 firmware and TWRP), then you would want to restore your phone back to factory stock 4.1.2 and then root and unlock the bootloader again with CASUAL. This would give you the most flexibility with flashing custom kernels, ROM's, etc...
Check out Section 1b in Droidstyle's restore guide at this link: http://forum.xda-developers.com/showthread.php?p=34891181. The guide has download links for the files you'll need to restore the phone back to the correct build version.

[Q] I9300 stuck at samsung logo, even after installing stock rom

Hello everyone,
I had CM11 installed on my Samsung galaxy S3 I9300. But I wanted to trade my phone with my dads and he wanted the simple stock rom (Android 4.3). I tried flashing the stock rom on it which went good until the last step when it should reboot itself. But i'm stuck at the samsung logo, I tried everything (pulling out battery, rebooting it, install stock rom again,...).
And I even can't get in recovery mode. The only possible mode in can get in is download mode. What can the problem be? Have I done something wrong? Should I try to install another stock rom from another country? Is there another way to get in recovery mode? I am from Belgium and I can't find the "Belgian stock rom", so I tried installing it from the Netherlands, is that the problem?
Thanks already.
What is the filename of the stock ROM you flashed and which options did you select in Odin?

First thing you should always do after flashing stock rom or any rom that causes a boot loop is to boot into recovery and factory reset then wipe cache this solves 90% of bootloops. Now I know you said you can't get into recovery so try flashing a custom recovery with odin then try booting into that and then factory reset.

You flashed stock firmware with Odin, was the flash successful ?
If you need to use recovery, flash TWRP or Philz, CWM is not updated anymore
Try flashing one of the firmwares in this thread.
yeah as far as odin was concerned the flash was successful and set the phone to reboot, but it still just hung at the samsung logo, and right ok im a bit out dated using cwm then it's been a while :Lthanks for the links i'll give it another crack now
thanks again

i've tried flashing CM and MIUI using the two recoveries you linked, still no joy. The download links for the firmware doesn't work but i found an equivalent that also has bootloader, csc files etc and still no joy, odin does it's business and says in green pass at the end of it all but it still hangs on the samsung logo, even when i installed miui, it would install all as planned, but then on the reboot it just hangs at the MIUI logo.
i'm lost completely i've never been defeated by a phone :L

I hope you guys can help me out with this problem.
Thank you in advance,

Have you tried flashing the latest stock ROM with Odin, performing a factory reset from stock recovery, and then using the phone for a while to verify functionality?

Definitely. Flash to stock should be the first thing you do if your phone goes into bootloop.
OK, I flashed the stock rom & recovery and did a factory reset. Until now everything is working fine, except the "Not registered on network" Error, which I have now
Any solution?
Does the phone show the correct imei? Have you tried manually searching and connecting to a network?
