[Q] My Galaxy GT-I9505 is dead

I wonder if anyone can suggest a remedy for my little problem, apart from throwing the phone in the bin.
My gt-i9505 recently stopped connecting to my provider and is showing a no service message at the bottom of the screen and a round circle with a line through it at the top. Samsung repair center say that the main pcb has failed but refuse to repair it saying that the phone was not destined for sale in the U.K but was intended for the Asia market.
My thoughts are that it cannot be the main pcb as the phone boots up o.k and also finds a satellite signal ok, the only things not working are the wi-fi and phone signal. Would I be correct in saying that these items are modular and can be swapped out? It may be a delicate job beyond my capabilities but if these parts are replaceable I do know someone that can do it.
It's a pity to dump the phone as it is only 12 months old and as new condition, so any suggestions or help would be gratefully received.
The phone is running the latest kitkat 4.4.2 ind is fully stock.

Bad efs folder. Is your imei and baseband correct?
Use/ask someone for a z3x box or a jtag.
"If someone helps, never forget to hit thanks ? "

Thanks for the reply, it's much appreciated. Yes my imei and baseband are all o.k. so I don't think it's the efs folder. The phone has never been 'played with' due to the knox problem negating the warranty. I have however played with an I9000 with many successes.
I also upgraded the phone to the latest version GNG8 hoping that this would cure the problem but that didn't work either. What would using a z3x box or jtag if it is a hardware fault?

Well as @MAX 404 once said...
The efs folder, even if shows the correct values, can go bad.
Before going too technical, did you try flashing the latest modem for your phone?
Do it too but before proceeding take an efs backup. (Many ways, many playstore apps to take efs backups)
Hardware fault. Unlikely in this case , but cannot be ruled out altogether.
Z3x box is a multi utility box which has the power to bring devices back to life and writes the imei codes and stuff properly once again.
And a JTAG + Z3x box have the ability to bring an almost dead mobo to life.
You can read more about it on xda, how z3x has saved lives. I wont say buy one, but you can always ask if someone has it.
"If someone helps, never forget to hit thanks ? "

Thanks once again for the reply. What I flashed was the newest software, I9505XXUGNG8, for the phone downloaded from the SamMobile firmware page which I thought contained the newest modem. I will however download the relevant modem and reflash. I will also ask around for someone with Z3x box, as I will be away from home now until Wednesday next I will be unable to reflash modem until then but I will report back as soon as possible with the results.

No. Just flash the modem via recovery (if a recovery modem file exists) or via odin.
After you flash keep the phone off for 30secs or more..and then turn it on..
See if anything improves..if nothing improves then just data wipe the phone..

I have now re-flashed the kernel inclusive of the wi-fi fix from this thread here
Code:
http://forum.xda-developers.com/showpost.php?p=50965837&postcount=2627
and the phone now connecting to the internet successfully. The circle with a line through is still at the top of the screen and the phone is still showing the no service message. With a sim card in place the network is showing as unknown, service state is showing as out of service but the phone number is showing correctly as is the imei. I will have a look around for someone with a Z3x box to see if they can help.
Thanks for all your suggestions.

Lost WiFi no clue

I rooted my S5 model SM G900T using Oden3 v 3.07 plus CF-Auto-Root-kltetmo-kltetmo-smg900t.tar.md5 send donation to chainfire. This was four days ago. All was better than fine until yesterday afternoon, then I tried to connect to a local hot spot. The phone said strong signal but could not connect.
Last thing I did was to run Pry-Fi didn't really understand the app so shut it down or I think I did, then after returning home I noticed while trying to connect to Google play store it said no network available.
Under settings WiFi the on off toggle is grayed out, it will flash green briefly when I go into advanced but it will not turn on.
Under App info WiFi Direct v everything is grayed out data is Zero and no cache is Zero
WiFi Direct Share is OK
I have a full Titanium Backup in Drop Box if that helps.
On the phone its Mobile ODIN Pro v 4.20 showing Kernel none Recovery none and on and on. Would like to have a nice ROM installed, but not there yet.
So I also think I didn't install something right
IMEI is present in software
I do have root that was my goal, but never to lose WiFi Oooh Mii God
What the heck is KNOX? Maybe its my router gosh

After flashing CF auto root, you tripped the knox fuse. That will give you a 0x1 status. This is only an issue if you need warranty, some say it voids it, others say not always. But once it's tripped it can't be undone. (and will have NO effect on Wi-Fi)
Are you on a stock original rom or a custom rom, did you uninstall pry-fi, and what else did you install.

Pry-fi is broken. I had similar issues after using it. Check my reply & fix in the pry-fi thread: http://forum.xda-developers.com/showpost.php?p=55449565&postcount=405

I don't think I installed anything but Pri Fy after rooting was assured then the app No-frills CPU Control,. I did not install a custom ROM. If it were the flash to auto root I would think I would have lost the wifi at that point not two days latter, I don't really know what Knox is but by having the stock software and resetting the phone to factory default I am sure I have not lost warranty as I have not damaged the phone. WiFi direct has no Cache or data
So I have to think maybe its related to Pri Fy
Thanks for the reply, I am late for work and would like to troubleshoot Pri Fy now and what it really does in relation to the other programs. As bkraptor in his post Pri Fy is broken so there seems to be issues with it. How ever his solution is in an area I have not venture yet.
Thanks again

this should give you tons of info on knox, but once tripped you can't untrip, you go from 0x0 to 0x1 permanently.

Thanks for the info about KNOX, voiding the warranty is not a primary concern. My primary concern is WIFI because I use it as my primary way I use the phone at home. It leaves my phone almost useless. I followed the link about Pri Fi but I never saw a solution for the S5 is there a clear work around. Should I use the warranty that I am paying for with the carrier and pay the deductible for a new phone. Wow I wish I could turn back the hands of time now, or have bought a different phone.
I really need a working phone with wifi, I can't lose it totally LOL.
Thanks,

Did you happen to make a back up of your rom before you installed pri-fy, if so you could wipe and install that, or you could download a custom Rom and try that. At worst you can down load a stock version of your rom and install with Odin and it will be fixed.

No I didn't make a back up before Pri Fi, I still have the stock ROM in the phone. Titanium didn't make a back up as I had thought or it put it somewhere other then where I supposed it to be. The phone is more wacked more then I thought I get line drops like crazy but maybe it was using wifi more then I thought. Thanks for helping me, where can I find a good stable ROM for this S5 now that I am in so deep might as well go all the way. I have insurance on the phone if I lost it and I almost lost it today, looked and looked for that thing. I have rooted several phones without issue, but one did brick but Samsung sent me a new one no problem, yet I have never tried to install a custom Rom.

Titanium b/u only backs up your apps not your whole rom.
If your on a 900t,i would check this thread out, it is stock and needs odin but should be close to what you have now. (you would want the full tar version, not just the modem and bootloader)
Stock, odin flashable
http://forum.xda-developers.com/showthread.php?p=57068686
If you have a t-mobile this is a great custom rom, You need a custom recovery like twrp or CWM as well for this option.
I like this recovery

[Q] Galaxy S5 b0rked using ODIN. IMEI lost. HELP!

Hi All
I have an Exynos Galaxy S5 (SM-G900H), and I done an ODIN update on it and it completely borked up the IMEI so it cannot be used on the network, and I cannot use Kies/Smartswitch to do a recovery as it rejects the serial number for some reason.
Is there anything I can do? I don't have a backup, and I can't seem to root it using towelroot. It's still running KitKat, not Lollipop.
I also tried multiple G900H firmwares but it borks up when flashing hidden.img but was able to get it going when a site suggests extracting the hidden.img and flashing it. The phone works, but the IMEI info is borked and I don't have a backup of the EFS.
Is the phone totally frigged and I would have to hock it on eBay as parts? I'm not sure if sending it to Samsung would help as that phone is a grey import. Do I have any other options?
Thanks in advance.

Anyone???

You tried to install the stock firmware ?

Yep, sure did, downloaded stock firmware from SAMFIRMWARE for the G900H. Tried Asian roms, Middle Eastern ROMS. I even tried a PIT file, but still no go.

I wonder why people won't reply. All I want is the original IMEI back, not this 0049 IMEI that seems to occur. I guess the phone is cactus and has to be sold for parts? I have tried everything under the sun to try and get it working from flashing ROMS, even tripping KNOX and rooting it.

Without backup you can't get back ur imei the only way is flash CERTIFICATE end QCN with octopus box

EFS folder is in the root section once you delete it , it does not really come back by flashing roms as rom flashing does not touch that folder. Once its corrupted there are different ways to get it back but you need special devices for it like mentioned earlier "octupus box" is one. Try to find a professional repair shop which also repairs software. Maybe they can help you. Samsung service centers also sometime repair IMEI if you have original purchase receipt and your phone isnt rooted...but you can still try. I messed up my Galaxy Alpha and instead of selling it for parts it sold it as a "Demo unit" with everything working but calls. Someone might use it as music player or a camera.

I have the same problem. SM-G900H made in Vietnam. Anybody may help me? Thanks in advance.

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance

Anyone??

under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware
https://www.blogtechtips.com/2017/06/24/easily-restore-samsung-device-firmware-with-smart-switch/
at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.

Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?

"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin
https://zfirmware.com/download-samsung-repair-firmwares/
5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.
https://www.sammobile.com/forum/threads/29914-SmartSwitch-Install-amp-update-or-replace-firmware

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!

Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!

Hi I am new to this but i have a samsung Tab A 10.1 SM-T595 from my university and it is locked with their knox cloud service so i have tried to restore OS with Odin and now i cant login or anything to their knox nor get android so i wanted help getting android to my tab without access to any settings is there any way? the Bootloader is locked aswell so i cannot use them i was searching for a workaround so i need help. i have maximum access to the connect to wifi screen before knox takes over and i lose previlges to anything cuz everything is blocked by their service

Hi im rlly sorry for the late reply but i reset the os bcuz i rlly had nothing to do in the previous version which was basically locked to a few apps that they control and I cannot access anything from it and i did it cuz one of my pals did the same and worked for him https://500px.com/photo/1018025656/IMG2020070120281001-by-Spin-Gaming/ this is the screen that shows up after wifi and then itll take you to the know login page with the id and password i just blurred out the university name

we have followed the exact same steps whereas he was able to access all settings in the setup screen and i wasnt and also what is a combination firmware and what all can i do with it also if you can find a u4 file can u send a link over will be very much helpful thank you

Deleted

its Fine no worries
Through the combination firmware i have unlocked the bootloader but if i flash the samsung os i still get the enrollment page so i was wondering if there is any other way and i am not able to flash twrp for some reason as it switches into a diff page and i dont know if there are any cutsom os for the tablet .i wont be using cellular anyways so if there is a custom os that works i can try

what he did was take a tablet owned/provided by his school who have a mdm service on it that is set to lock the device if it is wiped specicically to prevent ppl from modifying it or stealing it.
its basically an mdm lock.. you need to contact the school and ask them to remove the mdm lock. any time you connect to data which is required when mdm locked it will lock or set up the mdm again.
you cant get rid of it by simply flashing firmware...

oh there is but not gonna get it out of me.. im against it as it is unethical (borderline stealing)..
they put mdm on devices for a reason.. to top it off its supposed to be used for his education.. hopefully it wasnt bought with taxpayers money..
basically its tied to the imei/serial.. when it was first installed it sets flags on the device so depending on what they set up it can block factory reset, block ota upgrades including in download mode etc.
when it starts up it sees that it is tied to an mdm via the flags and requests internet connection to move forward at which it updates with tbe server and loads any policies or w.e back to the device

Okay, so I found out how to bypass it
1. You need to get the PIT file for your device. I found this guide on how to get it: https://www.getdroidtips.com/how-to-extract-pit-files-for-any-samsung-galaxy-device/
2. Once you have the PIT file boot your device into Download mode and connect it to your computer.
3. Load the stock firmware into Odin (BL, AP, CP, CSC OR if your firmware is just one file then load that file)
4. Then load the PIT file into Odin.
5. Go to the Options tab on Odin and make it look like this:
6. Go back to Log and click on Start
7. Wait for the firmware to flash and for your device to boot up.
8. Once it's done the enrollment page will be gone
If you have any problems or questions please let me know

and thats not permanent.. soon as it phones home itll register the mdm again..

I know but that's if you have the CSC file, if your firmware is just one file then it's not there.
Also, are you sure? The Nand Erase Option will Erase everything and reconstruct the EFS along with all other Partitions removing the MDM lock.

well yea, i meant regular 4 file firmware (or 5) ap bl cp csc home csc and userdata..
and yes.. they use your imei and/or sn which is enrolled in their portal/server so eventually they can send policy over the internet..
you can even get a trial and check it out urself.. type in knox manage or knox suite or knox configure etc.

But it still works, right? If it doesn't work, how is it even possible to bypass then? Wouldn't you have to change your IMEI and/or SN?
Edit: I also found this: https://www.isla7.net/how-to-remove-knox-mdm-on-samsung-devices/
