Did you unlock the bootloader?
There is a good guide here on how to back up your DRM keys before you experiment and loose your TA partition
Have you tried a factory reset?
Have you done a hard reset? button under flap next to sim.

Follow these instructions
Possibly read a bit more before randomly flashing roms...

I have done a factory reset, and also have done a 5.1 and 4.4 SW install. I have a feeling the custom ROM corruped my EFS. Does anyone have the EFS file they can share so i can try that?

It's a simple problem really, You flashed a custom ROM, and I think the baseband of your current ROM wasn't the same as the last one and therefore you are having this "no signal problem".
Simply use the baseband of a Firmware the same version as your current custom ROM
To do this you must flash it and exclude everything except baseband.

How do i go about doing that? i just want the easiest way to get it back to working condition, i dont care about the custom rom anymore. I restored the Stock 4.4.4 on it.
so currently its on the stock 4.4.4 with the current baseband and kernel
currently the baseband is 8974-AAAAANAZQ-00022-21
Kernel 3.4.0-perf-g1b1963a-02930-g23f7791

Keep Restarting After Restore ROM

I have rooted this phone and installed xrecovery~~ And I had tried to restore custom ROM from xrecovery but it still din worked out.... My phone keep restarting showing SONY ERICSSON AND HACKDROID!!!!
PLS ASSIST PLS~~~~
So you want to install that ROM by a backup right? Anyway, you should always do a full wipe after changing ROMs (not restoring your own backups).
Make sure that you have the Latest X8 Kernel and Baseband (xx015), i had this problem too and it was for this reason.

What version was my i9305 originally?

Hi Ive searched for ages but cant find an answer to this seemingly simple question.
I just purchased a i9305 which I'm trying to return to stock ROM. Problem is I've no idea what the original ROM was. The phone came with a modified rom and even though I can reset the flash counter and get it to say Samsung official ROM in ODIN, however it always says "sytem status:Modified."
Also in About>status it always says modifed-even with stock rom.
Cant get hold of the seller atm so I'm asking if theres a way to tell what the inherent stock rom of the phone is-not just the rom version I have installed now??
Thanks for your help, I hope i made myself somewhat clear.
Hey,
no way. I don't think there is a history.
Tell more about your phone, and maybe someone has the same and can tell you.
Btw. to get the modified status away, you have to install stock rom (kernel, boot, recovery and so on) and reset the flash counter. The device will check on every boot for custom things and set the counter to 1, if something were found.

You mean the phone doesn't really know what original factory version it was?
I installed a stock rom, reset the counter with triangle away and it even updated through Samsung kies after that. But still says modified.
Maybe I didn't install all the parts of stock rom? You said kernel etc so what exact elements do I have to make sure to install?
Thanks
Maybe. I know the csc will be stored, if it's a branded one. Thats all i know.
A complete stock rom contains system, hidden, recovery, data, modem. boot images.
So install with "mobile odin" (or odin from a pc) the recovery and boot image, restart, reset counter, restart. And check. If you install an original boot image, the kernel will also be stock.
Have you read other help threads? Some users have these issues also with stock roms, they had it from the beginning.
If you think, all is done and all went good without errors, you are maybe one of these users.
thanks.
By 'the recovery and boot image' do you mean PDA and bootloader options?
This is the current status info in 'About':
Model no: GT-i9305
Android version 4.1.2
Baseband version: i9305XXBLL5
KERNEL VERSION: 3.0.31-746327
[email protected] #1
SMP PREEMPT Wed Dec 26 etc...
2012
Build number: JZ054K.I9305XXBLL5
Then in Status:
Serial number: R31C914MNNK
Do I have stock kernel and recovery?
Thanks!

But isnt my warranty void if it still says 'SYSTEM STATUS: MODIFIED'??
Just wanted to let you know I sorted it.
I did the folowing, not sure which part or all bits helped.
Installed older stock kernel.
Installed old stock recovery.
In recovery mode did cache wipe AND full factory rest.
Then phone showed Status:Normal
and in ODIN showed No flash count and official and official!!!
Cheers. Great News.
Your warranty is void, if the status is modified.
i9305 bootloader
Is it possible to flash an older bootloader from ICS or 4.1.1 on my i9305?
I got the new bootloader when I flashed the 4.1.2 and now Triangle Away don't work anymore and I reaaly need it to root my phone and flash a new kernel and CWM...
Is it possible? I didn't found any answer about this... :S

TA still works if you use everything stock. And if you don't, then what's the point in resetting the counter? They'll deny warranty anyway

It won't reset the counter neither change the status with this new bootloaders.
But if I have my phone with everything stock why the hell will they deny the waranty, if the counter is 0 and the status is normal?
On 4.1.1 I had root on my phone and TA reseted the counter and put the status normal, and I needed to send it to warranty and they don't deny it, although I was with a custom rom...
I don't get what you are trying to tell me.

You are wrong. TA works perfectly with the latest bootloader, as long as you're absolutely stock. As in, stock unrooted ROM, stock recovery. And if you're not using stock, then you don't need TA because they will deny you warranty if you're on a custom ROM or not completely stock. That's what I meant

wifi/data problem

So suddenly my phones wifi and mobile data has stopped. I can't recover from a older back-up as i don't have one (tottaly forgot to make one) now when i try to repair it with PCC it says that the sofware has been modified and can't help ect.
I'm from belgium and i am now on fw 9.1.A1.140 but I can't seem to find the exect fw back in the thread. Can I also flash a other fw? My phone has root, unlocked bootloader doom kernel 7. Pleas some advise what should I do?
Try flashing doomkernel again in recovery.
Or try flashing a stock FTF in flashtool or a stock based custom rom.
Do a full factory reset before doing so and make sure you backup anything you want to keep
After leaving ma phone home for a day from school, things are back to normal.. Very strange.. Now going to see if the problem occurs again, but in the weekend I'm going to reset my phone, just to be sure. Btw, had already flashed the doomkernel again and it didn't work. Ether way, I'm happy now that for some reason everything is working again.
Sent from my LT30p, 4.1.2 stock, DooMKernel v7,root access, unlocked bootloader.

[Q] Need help! No sound in-call!?

Hi, I have a Samsung Galaxy S4 Active.
When I make a call i get no sound, microphone and earpiece are tested and working properly(I CAN'T HEAR THE PERSON, THE PERSON CAN'T HEAR ME).
Also, no sound when I put it on speaker.
I tried installing another stock rom but the problem persists..
First time it happened I removed battery and that solved the problem, now even removing the battery won't make it work.
Please help...
Nobody??
i537 or i9295?
Version of stock ROM?
Method of flash?
Tried factory reset?
I9295, 4.4.2 Kitkat, tried to flash through Odin.. tried factory reset and no result.
Also, I've wiped everything (data,system,boot,etc..) before flashing with Odin, using a custom recovery.

As you said you have checked the speaker phone and mic and confirm that it works so this eliminates any hardware issues.
Did you do the factory reset from within the phone in settings or through custom recovery. Suggest that you do the factory reset from within the phone in settings (prior backup of your internal sdcard data is required as this will get wiped out) as this solves most software / firmware issues. If still problem persists flash the entire firmware through odin (download from sammobile).
I have the same problem in the service menü i have no issue but when i make a call it doesnt work (sorry for my english)
Is it possible to make a logcat too see whats the Problem ?!

Not sure if logcat will show the issue, but yes we can check it out.
Normally these issues arise due to either mismatch in firmware (flashing different modem) or issues in the ROM itself. You can check by flashing entire firmware and if issue still persists then do a factory reset from settings (not cwm) and reflashing the firmware.
Did you flash any firmware files / modem and are you on stock touchwiz or custom ROM

Mic in speaker is a known issue in cm11. This has been fixed in 17.10 version. You can flash the 17.10 version and check
Factory reset from stock recovery only wipes the system and data while factory reset from within phone in settings resets much more than that.
Reflashing only stock ROM will not help... You need to flash the entire firmware through odin .

Ok which firmware (stock ROM) did you flash and can you send me a screenshot of your about from stock Rom
How can I know what modem suits my phone? I've flashed another stock rom from another region(earpiece and mic didn't work before) and the issue is still present.

It is always recommended to flash the modem for your region. ROM's generally are independent of region unless you have flashed the entire firmware. UCNE5 firmware so far seems to be safe and is known to work for most regions.
Which country are you from and which ROM did you flash.
I'm having the same problem, using CM11 or Stock.
Phone worked grate till 2 month ago (bougth on february). Tested different modems, different SIMS.
¿Maybe a hardware problem? ¿Maybe is bootloader/KNOX related? I think this as was using last TW from UK (I9295XXUCNH2), I'm from Argentina.

Flashing modem from a different region/carrier is sometimes known to cause this issue with certain carriers. Recommend that you flash only the modem for your region and carrier (not the entire firmware) and check it out else try flashing the entire firmware.
If mic and speaker is working fine in other apps then it will not be a hardware issue.

hmm..this is a tricky one.. You could try the NE5 modem from my drive to start with and see if it works, though I would recommend that you flash the one that you were on before while it was working properly.
Tested NE5 before posting, same results. Using official 20141018.
Original modem was 4.2.2, is there a modem repository?

Just one more question? are you using GSM or LTE, you could start by trying GSM mode only. Also just remembered this thread I stumbled upon yesterday which may be useful in unlocking the band used in your country/carrier.

Edit: another one which I searched and found today

Did a little search and you may refer to the below links for the bands for Argentina as well as those on I9295 which could be helpful

Bro I tried flashing persues kernel cause somewhere I have read that by flashing persues kernel you can get the phone back to normal.
So I flashed the kernel and after that it showed me baseband number but imei was showing me only 0 nothing else.
I updated the phone to 4.4.4 so check it will work or not but was of no use.
Can u help me by giving me the link of a complete stock with all the file for GT-I9305 uk version.
Hi,Mustakim_456,I would recommend you first to try this method-flash Param.bin from this thread:http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915
It's simple and quick,using Odin.Good look.If this doesn`t work, try to flash ROM stock from here:http://samsung-updates.com/device/?id=GT-I9305
You will find versions 4.1.2;4.3 and 4.4.4.
