Phone does not connect to Network (started after being stuck at samsung logo)

Hi everyone,
I rooted my note and was using Jon ROM V3 for the last 3 months. Never had any malicious apps and my phone was working as usual.
Yesterday I took my phone and see that it is stuck at Samsung logo (an hour ago it was working fine). Tried reset and re-flashed ROM but no luck.
Later through download mode i flashed Official Indian Firmware(I live in India). Now I by passed the logo screen and the phone shows full signal bars but not able to connect to carrier network.
(tried all basic work out like removing battery/sim and re-inserting to phone and boot up)
I pressed power key and it did not show the power menu , it directly switched off mobile.
I rooted again with Philz kernel and flashed JON ROM. Still i see that my phone is not able to connect to any network. Also I observe that even here on this ROM when i press power key it directly turns off.
This is weird. I thought my IMEI was wiped off but im lucky to see that its still there.
I need your help. Im without my phone for the last 2 days now.

Jonathan

Note - I find that my IMEI number has been changed (to some generic IMEI 004999010640000) after i flashed the official firmware !!!! that's why it is not connecting to any network.
Someone please help me.

How did you flash the official firmware?
was it a tar file or a zip? I mean did you use odin?

It was a tar file The official Indian firmware I got from sammobile

either a glitch or you selected by accident clear efs.
anyways without efs backup hard to recover emei.
Do you get the simcard enter pinscreen on boot? If you dont then its not imei, if you do then you need someone like cvxcvx, search to fix it. That or Samsung

No I do not enter pin for simcard. I see my imei has been changed to 004999010640000. I tired fixing one problem and got onto another.
I guess there is no way other than sending my device to Samsung !
Anyways I appreciate your help. Thanks

You have a so called "developer IMEI". If you didn't safe your EFS then there is no real chance to restore it yourself.
There is a member (cxlcxl) who has hardware and can restore the original IMEI remotely.
But you still can use your device. Try to change the Sim Pin in the settings: you can use the same Pin for old and new (this is easier for me because sometimes I forget the new number).
After this the network connection should come back.
My workaround in my Pristine Custom Rom: one different jar-file that doesn't have the checks on startup from my old XXLSC dump. With this it works completely normal: Sim and Pin are always recognized from startup. I'm using this for many months now.

[Solved] NV IMEI RESTORE ISSUE - Samsung i9305 optus AUS

IF THIS HAS BEEN SOLVED SOMEWHERE PLEASE TELL ME ASAP
sorry this is first post. Cheers
Hello XDA!
man ive nervous to post..
BUT i have come a null/null IMEI reading after a CM10.1 bootloop issue and trying to flash a new CM.
I have been a XDA follower for about 9 months but I have never needed to post for anything, as you have carried all of the lords answers. :angel:
I have done, stock firmware reset, Param bin, wiped all done it again. etc etc.
Many a conclusion has led me to probably a service repair centre.
I believe one option will still work for my IMEI restore but my phone comes up with a command that makes no sense.
Any help would be appreciated.
I am currently using QPST Configuration to write my IMEI back to my phone.
I have got these programs http://forum.xda-developers.com/showthread.php?t=1804117
Aswell as another handy IMEI converter to make sure my IMEI HEX conversion correct. (sorry cannot link. cannot find)
I have been using QPST and can follow all steps, except my phone WILL not show on on active phones.
I have reinstalled drivers and followed all necessary steps.
I have tried it in recovery mode also in QPST and no active phone still.
I believe i can get this to work, just need it to recognize my phone, and ill write the IMEI and hopefully..
Voila.. i can call the GF and tell her to chill. :good:
IS RNDIS different to RNMET? (how big of an impact will this play on the process)
In qualcomm settings i get "RNDIS + DM + MODEM" but i do not get "RNMET + "

[Q][GT-I9305] EFS, IMEI Repair

Okay everybody,
I decided to write a new thread for my problem because I think my prob is a very special thing.
I'm from germany, so please don't wonder about my english. I think it is a understandable.
The story begins with a software update for my GT-I9305. After the update, the IMEI was just "null", after some work with google I found out that the efs partition was broken. With my bad knowledge for this case, I destroyed the whole EFS folder. I installed perseus kernel. And, there it was! The whole and correct IMEI. The solution was the perseus kernel (stock doesn't work, neither reflash). But then, after a while the phone doesn't boot anymore. I flashed Android 4.4.4 and my phone was revived but the IMEI was again "null". I have no backup or anything else!
So I spent approximately 20 hours or more to understand the efs thing. I found much solutions but nothing worked for me. So, here I am.
What I've tried before
-reflash KitKat
-reflash Perseus (not compatible anymore)
-formatting efs partition for a blank and new EFS for editing
-tried to edit nv_data.bin with HEX
-tried to backup efs with a 3rd party app and edit this with hex (the app doesn't support my GT-I9305)
and then, there it was:
-tried to use a working EFS partition from another GT-I9305
-editing with Qualcomm NV Tools! (I think THIS is the solution!)
I tried NV-items_reader_writer (1.0) and EFS Professional (2.1.73), but in both can't find my phone:
What I've done in NV-items_reader_writer
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened NV-items_reader_writer
-checked the both boxes near the SPC box
-selected the right port (last: COM4)
-clicked on "connect"
-clicked on "read"
-> here it search the phone, but it can't find it and says "Failed.. Phone does not answer"
What I've done in EFS Professional
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened EFS Pro
-clicked on "Qualcomm NV Tools"
-refreshed the Available COM Ports
-selected "SAMSUNG Mobile USB Serial Port" (last COM4)
-clicked on "Connect"
-> Here it takes few seconds and he stops and says: "Phone connection has been lost!" and "Unable to send SPC to the Phone!"
What I've tried to solve this problem
-tried QUALCOMM USB Settings: "DM + MODEM + ADB"
-reinstall all Samsung drivers
-tried to install Samsung Modem with Qualcomm drivers (failed due to wrong platform; I've Win7 X64)
-reinstall Samsung Kies (for actual drivers)
-tried to dial *#9090# (in my case, this menu is totaly blank)
-tried in factory mode
It could be that I forgot some....
Now, my question to you all is, do you know what I've done wrong? I mean, this is working for the most users, but why not for me? What do you think? Did you think I really forgot something?
Some informations:
Phone: GT-I9305
Android: 4.4.4 KitKat
Kernel: Stock (3.0.31-2760029 ; [email protected] #1 ; Fri Sep 12 13:08:24 KST 2014)
Buildnumber: KTU84P.I9305XXUFNI3
Windows: Windows 7 X64
Do you need more informations? Post it!
Please help me, I want to bring this phone back to life!
And yes I know, to change the IMEI to a number which is not your own is ILLEGAL and to prevent this, it is not well seen to talk about, but this is MY PHONE and I want to change the "null" IMEI and IMSI to MY ORIGINAL IMEI. If this is a problem, I can send a PM to an mod with my phone (where you can see the IMEI), my username on a sheet of paper and the original box with the IMEI printed on. All on one picture!
Simply... I need a hero! Be MY HERO!

im in the exact same problem as you. the reason nv tools and efs reader is not seeing your phone is because you have NULL well usb wont work. so try installing the original 4.1.1 firmware, then install perseus, then nv tools and efs software will see your phone. if you end up fixing it please help me out. upgrading to a later firmware is where I get stuck. just stays on the boot logo. and like you said perseus isn't compatible. you seem to know how to use nv tools so hopefully you can get somewhere. as I don't no how to use it. GOOD LUCK.

take your phone to the samsung if you have warranty.otherwise give to a phone repair shop for repair because your problem can only be solved with special boxes and equipments etc, and they have it. it will not cost too much.

I tried this, already. But I can't downgrade from 4.4.4. I don't read very much about this. I just know that this is a new security option from samsung (or Android)... I will tell you when I know more

The warranty is already expired...
This will be the last step I will do. Before this, I will try my very best to do this at home... But thank you for this tip
Edit:
What do you all think about this idea:
-I try to find somebody with a working EFS on GT-I9305 Android 4.4.4
-I get a backup from him
-I restore this backup to my phone
-I edit the duplicated IMEI with NV Tool to my IMEI
This requires that the NV Tool will with work with an existing IMEI and the the phone will be THE WHOLE TIME IN PLANE MODE to prevent IMEI ban...
What do you think? Will this work? Do I need somebody from germany (DBT) or is this not needed?

Take it to a phone repair shop they might have a way to fix it. And if they don't they might know someone who can and it would likely be cheaper than Samsung service center

If you were to 4.4.4 Official Stock rom can`t do downgrade the bootloader.What you have done is downgrade to Firmware with extracted knox bootloader.But you still with EFS corrupt partition.

Hm okay. I applied a "old bootloader" before here from xda. I don't know what it was exactly. There was a boot.so or so in it.
I will try my best. I mean, if I can beat this, this is a really great success for me. My next step is to restore a full NAND backup from a friends of mine (from a GT-I9305).
I wondered about that, after I restored a working EFS, there were no NV data.

Hi guys, i had the same issue: after a botched restore of nandroid backup (something to do with it being over 2GB, different story though), I lost IMEI (null/null) and no baseband.
I was running CM so I tried to flash the original Samsung ROM, to no avail. Then a whole bunch of other stuff that didn't work, until:
- I flashed kitkat (which failed due to some error in the install script, dunno why)
- then flashed my last nandroid, which I had already flashed with no restoration of phone functionality, HOWEVER,
- I then flashed over that nandroid the modem files (see here: dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f) , mine was Modem-I9305-XXUENE2.zip for i9305 LTE Intl.
- tadaa! fixed
hope this helkps anyone, took me some 20 hours of tinkering

"Trying to flash" , what exactly did you flash ?
How do you flash it ?
Why dont you flash TWRP followed by ROM of any choice ?
NV normally contained in EFS partition, which can be backed up and flash from TWRP and QPST.
But again, your description is far from clear for us to help you.

When you flash using TWRP, did you actually managed to boot into system ? Or it stuck in recovery ?
Where did the nv corrupted notification appear when u were using TWRP ?
Prior to facing this issue, what you actually did ? I mean, did this phone work before ? Before you start getting this error, what you did, what you install, what you flash, what you delete ? Or did it just suddenly happen with nothing modified ?

This is absolutely not a issue, that requires using Qpst
You simply need to wipe data and follow the on screen prompts. (You will lose all data on your phone.) However the phone will work again.

Sorry that you are having these issues, But my comment was based on the photo that was posted on the OP. Typically formatting is the resolution. If you no longer have that screen available, you should contact an authorised repair center to fix it for you.
Otherwise If the phone is bound to your account, you could try what is listed here: https://www.mobilerdx.com/2019/02/xiaomi-mi-8-test-point-boot-xiaomi-mi-8-into-edl-9008-mode.html
Scams or Actual Fixes?
I have recently read about supposed hacks that according to a couple of Chinese BBS sites, has worked for some that require buying a specialised Jtag programming tool which cost about $60, that you use along with altered versions of following files: prog_emmc_firehose_8909.mbn.elf, mi8 persist image, rawprogram0, frp and a patch file. All of which that can all be obtained from here: https://romprovider.com/2019/09/mi-account-remove-xiaomi/ ( UMT Download)
Supposedly Chimera is another option: https://chimeratool.com/en/docs Again I have not used any of these tools with the mi8, I am merely sharing what I read about recently.
By the time you have spent the money acquiring the tools, it seems that you are better off just mailing the phone off to be repaired by an official repair center. Here is a web page that provides a list of official repair centers : https://www.pinoytechnoguide.com/2014/06/xiaomi-service-centers.html
Good Luck and try anything mentioned above at your own risk.
Edit: Have you tried the Flashall.bat method?
That should work since you are seeing the com port.

Hello, thank you for your answer, the mother is not linked to my account I disconnected to do the experiments. in my country i don't have a xiaomi assistance center, i get the error missmatching image and device.
There is no other way to unbrick without buying these tools so expensive that you mentioned

root cause of your issue is that you play with wrong qcn and messed up the nv,
wince you cant plugged to qpst, you need someone to make EFS backup for you torestore from twrp

You can restore phones imei if your bootloader is unlocked but only 2nd sim slot will work

How can I do this? Can you help me please?

You need backup EFS and Modem via TWRP first(better with OrangeFox). After you need Magisk first and some manipulation with QCN file via QPST. I will write it later

Maui Meta is for MTK cpu phones. You need QPST

Note 8 Pro is MTK Device

Question Help with an unbricked Poco M3 Pro

Hello guys, after some struggle trying to unbrick my poco m3 pro, i faced a new probem, my IMEI has gone, as a noob that i am, i didn't made any kind of backup, i'm trying alot of ways, and still i didn't had any luck to re-write my IMEI (i still jave the numbem on the box of the phone) to the device, i'm using linux, almost everything that i found is to windows, does jave any kind of tool for linux, or i'll have to put windows on my laptop just for this porpouse?
there is anychance to use mtkdrive tool, the same used to bypass security for sp tools to do this ?
thanks for now

if your mobile services works, write imei is not necessary. and it's a dangerous operation. so if your devices now works fine, my suggestion is DON'T TOUCH ANYTHING
all my old phones that after modding lost originals imei worked without problems
a mobile sim could work also with all imei numbers=0

sadly my mobile service don't work, i keep zero signal, and when i try to get IMEI numbers on Settings > About device, it says unknown on both IMEis

ok
first try your sim into another device to be sure is not damaged
second search xiaomi redmi note 10 5g fastboot engineering rom and flash. this rom should repair some high problems like your.
if boot and all work fine, update to miui13. good luck

thx, i'll try to find that rom, i already tried my sim on another devices, and works flawless

so... after long searchs and alot of re-bricks, i finally managed to instal an ENG rom, and had found some NVRAM and NVDATA files to flash too, with those i finally made to get some signal, but still my IMEIs is unknown when i get to about phone, and when i type *#06# i get nothing, not even 0000's. now how do i update from eng rom to a more updated version of miui without losing those configuration files

its only information and you can use Maui Meta in Meta mode if you enter edl/testpoint, for me the first time lost two imei only return The Second imei, but send to waranty and change the Phone.
of coursed use a Semi Profesional Tools.

Did you find a fix? And where did you go wrong? Please let us know the mistakes you made so that we don't.
