[Q] Urgent Help. Diag mode + Imei-0 Baseband-Unknown - AT&T Samsung Galaxy S II Skyrocket SGH-I727

So basically my imei has changed to 0 and baseband to unknown, Suddenly one day I lost signal and network.
I tried flashing different roms and radios and nothing worked, then i researched and found out that I will have to fix my efs which is possible by QPTS.
I need to know how to put my phone to DIAG mode to use QPTS, currently using cynogenmod 10.1 nightly on my Samsung SGH- I727 At&t Skyrocket.
So tellme how ?
Will I have to return to a stable release to use Diag or any other rom?
p.s i cant switch the stock using odin as it gets stuck in a boot loop but can flash other roms.
So if you know about enabling Diag mode on any other rom please tellme how and what rom is it.
Please help to restore my corrupt efs (which i read happens sometimes with flashing roms). If you know any other way also.

I already viewed this and tried.
I have a keystr file, whats missing is the nv_data.bin and other such files which hold the imei info.

You can rewrite you imei (if you have it on the back of your phone or in phone documents) with these tools (software & hardware) http://goo.gl/54mtk. Here's a guide for it http://goo.gl/wtW29.
Also you could try this alternative http://goo.gl/ghcJn ..
None of that is free..
And finally you could try helping the op of this thread to add compatibility for skyrocket, this would be free.

I have no idea what you are talking about, but below may be a method for getting into USB Diag mode.
Just to be clear: I have not read this thread as it is for Verizon Galaxy S3. If you try that on our phone you will do that on your own risk.
I simply suggested you got in touch with amoamare and see if he can help you or add support for our phone in his app.
Some phones must be put into USB Diagnostics mode to do the
unlocking. On your phone, enter *#9090#. Does a menu open? If yes,
select - [1] Uart_null_usb_diag (usually the first option). Depending
on your phone model, this may be called differently. Once selected,
watch for words like “USB Diag” and select such an option. If entering
*#9090# doesn’t do anything, try *#7284# and see whether you can
find anything similar to - [1] Uart_null_usb_diag. If there is no such
thing, ignore this entire step!

Imei problem

Dear friends
I used lg updater but after that I lost the signal
When I checked *#06# it didn't show me the imei
When I go to about imei it show 0
I searched the problem on 3d I didn't found any one have this problem
But I found some 2x have it and they solve it by baseband flashing
So did any one have the same problem before and how dix you solve it ?
Thank you all

very similiar problem, imei empty, id not found.
is not detecting the sim card
and the only way to switch it up is with charger of the wall conected imposible to do with the usb
You should see the IMEI under Settings -> About Phone -> Status
Att flashed kz with lg update
I am having the same issues as you guys.. I flashed the KZ file with lg update software as explained in the XDA thread but I could not get the process to work right. My phone kept disconnecting at 28% and it would not turn on no matter what I did. It would only make a short vibrate as if it was turning on, and the computer would notice it but only for a short time. And never once did a light on the screen, or LG logo, or anything at all ever appear.
I figured I had really screwed it up, but when I plugged it into the wall it booted up perfectly. All my data was in tact and the rom i had flashed through cwm was still there, not the kdz file that I flashed with the lg software.. I noticed that my sim card did not come up as being in the phone at all. I looked in system setting status and noticed that all info related to my imei said unknown. I opened up the mfg app (277634#*# from the phone app).. Under "version info" then "factory version" my phone now says xmm6260.. It always used to say p925..etc... Even after flashing the zip to debrand from at&t this never changed from p925 even when every other aspect of my phone has.. I was hoping maybe once I put in an activated sim card everything would be fine and my phone would be unlocked which is why i flashed through lg software.. But seeing as how other people are having this similar issue and their phones not seeing the sim card, well im looking for some advice.. Should I try and re flash kdz file through lg software again? if i do, im going to do it on my XP computer this time, not Windows 7..
Just wanted to add that I did try wiping data and cache from cm and no dice.. Root and CMW work fine but no matter what I do, if my phone is turned off, i cannot boot up or boot to cwm or boot at all unless i plug the phone into a wall carger and then once its on it stays on and i can unlug.. SORRY ABOUT THE LONG POST, THANKS IN ADVANCE FOR ANY HELP..
Hello, I am having the same problemws as you.. Have you found anything out yet? I'm trying to get some answers.. Did you try re flashing kdz with lg update?

Hi guys
I'm getting exactly the same thing aswell!! I wonder what the problem could be? I can boot the phone up if I plug it into the wall charger, but have no signal at all.

Is there any soltion? Please.
Reflash the phone.
Take out battery. hold down the up key, plug in cable to computer.
Wait till it installs or activates the necessary drivers. eg usb protocol etc.
Then run the recovery via lg tool by entering your imei number in the application.
This will install the latest stock version based on your imei (including baseband)

Thanks, I tried but it did not work.
I tried everything possible. KDZ flashed about 20 times. Flashed bin and fls files many times. I do not know what more to try. When I put androuid 2.2 After a while the cell phone turned on appears IMEI and IMESV, but disappeared again after reboot.
I put the phone in the CP - USB (3845#*920# port settings cp-usb) mode and I connect with hyper terminal when I type AT%IMEI my modem gives me IMEI. When I type AT%IMEI=? back to me is: [IMEI part1 [7] + IMEI part2 [8]] but I do not know how to write it. I tried all possible combinations and I still write IMEI write error. (AT%IMEI=xxxxxxxx + xxxxxxx AT%IMEI= x, x, x, x, x, x, x, x, x, x, x, x, x, x, x, ......) I found [LGFlash Tool 1.0]LGP920_20120213_Download_WriteIMEI.dll at the CSMG server and I tried with LG flash tool so that instead of stock dll I put this dll but it failed. It gives me an error not read IMEI. There may be a BIN file that is used whit it??? Here's the dll if anyone wants to try.
All this hapend after simple reboot. I found service manual for LG internal use it says that this could happen becouse of fault in firmware, and that after write IMEI firmware should be updated to V21A to prevent this to happen. So some early firmware cause it.
I dont have warranty.
sorry for bad english.
Interesting.
When you run the official recovery tool and it asks you to enter your Imei, does it go ahead with the process and fully complete 100% with the flashing?
Do the problems then still occur? If you can get your phone to turn on at anytime, have you tried a full factory reset after that?

Yes it completes at 100% everything is ok I can turn it on, off, go into recovery and everything. Device is working perfect but android cant see IMEI, that is writen in eeprom. I tried factory reset numeros times, no help. When i start lgupdate official tool, tool also reads correct IMEI from device.
Seems an issue with the baseband updating/corrupted, although the lg tool flash recovery should have updated this as well. Have you tried the other flash methods (try one of the kdz roms in this forum. eg v21a for europe gingerbread) and use this flashing method (you would need to block the lg updater from accessing the net) There is a tutorial on this in this forum. it works via forcing a rom update and redirecting it into the lg flash program

I did that metod too. There is any metod here on this forum that I didnt try. Thanks for help. I dont know is it baseband or CP chip problem.
This may be guesswork, but if the baseband is flashed in a specific area of the phones nand space, perhaps the nand blocks there are corrupt which causes it to fail. Perhaps with some additional tools, it may be possible to format this area, marking the bad blocks as bad preventing the baseband data from writing to these area's. Just guesswork here.
Have you tried flashing other baseband versions seperately

[Q] Galaxy gets to download mode, can't flash ROM

After a failed ROM flash, I am now unable to flash any ROM onto my Galaxy s 4G except for PDA_UXKG3_rooted_no_bootloaders_v2.tar.md5. However, this ROM won't do since I have no service when I turn on my phone. I assume this ROM is for another carrier or a different type of Galaxy.
I can get into download mode and recovery mode.
I have tried many different ROMS (rooted and stocked, got them from http://forum.xda-developers.com/wik..._Rooted.2C_Deodexed.2C_Busyboxed_ROM_packages) for my phone and none of them will finish the flash process, Odin3 always fails at modem.bin. I have tried numerous times to reset to factory defaults from the Recovery Mode but the phone says it can't access some ATT folder.
I am using Odin3 1.85 and have a Samsung Galaxy s 4g sgh-i997.
Anyone have any ideas on how to get my phone working again? At this point I just want any ROM that gives me service to work on there. I
Thanks.

I think the I997 is an Infuse 4G, not the Galaxy S 4G. You may want to look in the Infuse 4G forums. I would love to try and help but I don't know that phone model.
In one tutorial I found, it said I needed a full firmware package, does anyone have a link where I can get that?
Even if I have a different model, does anyone have any suggestions on getting my phone back to stock? Or just working somehow? I would guess that if I can get into download mode, I should be able to get it working again.

That's correct; getting into download mode should be able to get you there again. Here's a thread on the Infuse 4G forum that has a lot of different ROMs:

Thanks guys. I followed this tutorial and it worked perfectly. droidangel.blogspot.com/2011/07/guide-how-to-unbrick-and-fix-your.html
I guess I just needed the PIT, PDA and PHONE (modem) files. Previously I was only using the PDA file.

Moving to Q&A

No network

First of all I wanted to let you know that I've tried everything in my power before I post my problem here. I found it very difficult to understand some solutions that are discussed here. But after 3 days I have decided to try it here.
I just bought a LG P920 for my son (can't afford a new phone now) and he got a present. A car you can control with your phone, but it didn't work because I thought the android version wasn't sufficient enough so I flashed a custom rom:
CyanogenMod -version Android 4.1.2
10-20121227-NIGHTLY-p920
After several other roms, and I tried a lot, I still have no baseband. It says: unknown
Which rom can I flash to get it back? Or is there an easy way to get the baseband? I saw some tutorials but I found them very hard to do. I really hope somebody has a solution for my son and me. Excuse my english, I'm from Holland
You may simply need to set up your APN; my tutorial covers that, and also flashing baseband. I have not tried CM so I am not sure if there are any issues there, however.
http://forum.xda-developers.com/showthread.php?t=2195753
Thank you very much for your response and I've looked at your tutorial but I have really no idea what I'm supposed to do. Rooting and flashing a custom rom is easy but this is something out-of-my-league.
Wich flash tool do I have to use for flashing a baseband? How does this go? I'm really sorry about this but this is completely new for me.

I post it twice accidentally ...:silly:
You would set up pc drivers as in part 1. Then use Flash Tool to flash a baseband (.fls file). There are a few included in the download files, or there is a link there to other basebands for different countries. You do not need to install ICS or the custom ROM if you do nit want.
You may not need to do all that; you just might need to set up the APN for your particular network and SIM if you have not tried that already.

Now I figured out how to use the SmartFlash Tool and as soon as I want to start the flash process the app crashes
You have to use the program in XP mode and run it as admin.

You're right and it worked. It all went well and I got the complete green line at the end, so I thought this is it. I'm back to stock!
But now it says when I check
Android-version:
2.3.5
Baseband-version:
L6260_MODEM_SIC_01.1042.00
Kernel=-version:

and still no possibility to make a call ... it still says: No service

How do I do that? I also checked my imei number and there's isn't one. So that was the issue all the time. I've searched a way to retrieve it and tried it. But I got stuck at point 6. Got this from here: http://forum.xda-developers.com/showthread.php?t=1734330
Restoring IMEI
1. Connect phone by USB
2. Activate USB debug mode
3. Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4. Select Port Settings -> Select CP Image Download
5. A new device should appear at let it install
6. Open Tutty and select serial protocol. Click on open
7. Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8. Type at%imei, it should display a dummy IMEI
9. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10. Reboot phone
I have never lost IMEI so dunno there. APN is in system settings, more...

Bricked - Stuck on Samsung Galaxy Note 10.1 Screen

Hi,
I bought a bricked Galaxy Note 10.1 GT-N8000 and managed to flash stock firmware and booted correctly except for a strange Watermark on screen which showed device specs. Then I tried flashing German Kitkat version thru ODIN which failed, now the device is stuck on Galaxy Note 10.1 screen even though I have tried flashing ODIN many times and it has shown PASS but doesn't go beyond that. It can't even go get into recovery (only can get to ODIN mode). Please help me as i can't go beyond that even though i have searched a lot google, no one seems to have gotten any solution.
34 views but no suggestion!!! It seems mighty developers never bought this phone to suggest something. It's strange ODIN can flash and shows success (firmware or any recovery) but nothing seems to install and make it boot. Pl someone got some idea?

Have you tried flashing a custom rom?.
Just realised you said it wouldn't go into recovery.
Try flashing from another pc
Which version of ODIN are you using?.
No haven't tried custom ROM but probably this device was never rooted but can give that a try. Yes it won't go into recovery at all. I will give try from another PC. I have tried ODIN v. 1.85 and v3.09.

I think it might be a driver issue with your pc if it won't work with v1.85.
Trying reinstalling the Samsung drivers on your pc.
I flashed stock firmware before with the same PC and it worked and I have tried to use same ODIN and same stock firmware which worked before. Even now ODIN says PASS, infact there is no failure at all but device itself is stuck on "Samsung Galaxy Note 10.1" splash screen. I have tried restarting PC, using different USB ports but ODIN always says PASS without problem but device condition is same. I think may be i should change firmware/ stock recovery even though previously the same worked. I am at a loss, don't know what to do?
P.S: Edit: as i was writing these comments I thought of trying out same german kitkat version which earlier broke my device and this time it succeeded and at least device has come out of that splash screen though it is still stuck samsung animation screen. so i will try more and will update. any suggestions are welcome. thanks
ok, now it's possible to get into stock recovery at least, although it shows "E:failed to mount /efs (Invalid argument)" and " Applied the CSC-code : unknown". What to do now? kindly advise
Finally managed to ODIN a stock firmware to work correctly and device is able to boot but show "Broadband: Unknown". Thanks for your help

Can you check your IMEI if its available in setting/device? If its not your EFS is missing or corrupt.
yes, IMEI is Unknown! that means EFS is corrupt! I know the IMEI, I have the box, how can i restore it?

Thanks a lot for the link. I will go through it deeply and try it out and will come back.
Just some food for thought! Since i bought this device bricked and never knew which firmware it came with and tried different firmwares randomly until i found one that could work only with "Factory Mode". My question;
1. Could it be that I flashed a wrong firmware causing this thing to go Factory Mode?
2. Or must it be corrupt EFS folder?
I am asking because now i rooted my device, it is showing one EFS folder and when i tried to flash Philz recovery over TWRP it gave me error that " This package is for 'c).p4noterf.n8000.GT-N8000' devices; this is a 'p4notewifi'.
E:Unable to mount '/efs'.
Any suggestions? Please
I think this efs folder is generated automatically by the android when it can't find one because when i checked it was an empty folder, nothing inside. so may the issue is of broken efs system folder. Can't create my own IMEI since i have the box and IMEI is written on it.
Does this device use SIM to make calls or just for data download? Couldn't figure out! Is there a simple way to get rid of the "Factory Mode"? may be i don't need all that SIM functionality after all but certainly want to get rid of that "Factory Mode".
Can I try this one

Mine is wifi+3G version, its called GT-N8000. Mine was bricked before and I flashed it using ODIN (its available everywhere almost) and stock firmware (you need to use the one installed on it from factory, you can find download link from sammobile site but be careful download the one that is specific for you model no.). Then describe your problem may be i can help you.

Bricked S6 please help

Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006

OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks

1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks

Thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

Thanks silly question but how do I know if my efs is ok or corrupted?

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.

Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.
