[Q] Recover service

I just went back to stock and was trying to recover my EMEI but it matches the one on the back of my device but i still have no service and i have no ERI version. I was trying to follow this method http://forum.xda-developers.com/showthread.php?t=1867442 and got stuck at step 4 because i couldn't find where to click connect or the IMEI number in the ports section.
I also tried http://forum.xda-developers.com/showthread.php?t=1802024 but every time i get to step 15 it says ports are either busy or not working correctly.
I know Im a noob but Im following every step what am i doing wrong and how do i fix this no service issue?

HELP! H950 ATT backup needed

Hi. I'm lost. I've bricked my freshly purchased H950 because of being in haste to update the firmware to 5.1.1. I've accidentally installed a H955 KDZ over my stock 5.0.1 AT&T H950 firmware. As expected, the device is bricked (everything works except the cell network). I've tried everything, spent about 8 hours with no result. Can't root it as well.
The IMEI and Baseband status is "Unknown" (lost EFS partitions).
Please, if it;s possible, give me an advice how to restore it to its original ATT firmware. I know that ATT hasn't published the TOT file of their firmware. Maybe I could restore it using someone's backed up files?
I'm outside of the US for the next 7 months so I won't be able to return it
Please help me, this is urgent.

Well the good new is that your cell phone works so it is not brick. Cell network probably doesnt work because H955 use different bands than H950. I dont think you will be able to go back to ATT rom because like you mentioned there is no kdz for it. But on the bright side you can try to use the H950PR KDZ to flash your cell. this is totally compatible with the H950 from ATT. You can always wait for the someone more knowledgeable to answer but I am almost sure that it should work.
http://forum.xda-developers.com/g-flex2/general/kdz-compatible-att-h950-t3180847

I've installed the h950pr and there the cell network is still not working
In case if i find a person who has a similar device with Att firmware, how can i make a backup of it in order to flash my device?

I've managed to root my semi-bricked H950. But the imei and baseband version are still unknown. What should I do?

baseband ok. just the imei has 0 value. help please

follow THIS guide and you should be ok.
Use your own imei embedded in the back of the phone or the original box.

Check your PM.

Does anybody know how to write IMEI on the H950 without octopus box? Can't do it in QPST, DFS, EFS pro because it sn't recognized as a phone / doesn't answer.
Everything works, I can even make calls, just the imei value is 0.

Finally I did it!!!

Did you use qpst? Or which tool?

Yeah. I used QPST. I had to open cmd, enter "adb shell", then " su", then "echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable". After that you can backup Nv via QPST.

Im glad you informed yourself and solved your own issue. ?

[Help] Recovered from soft brick, no service now

Soft bricked my phone installing the android 10 open beta.
All good, recovered it (i have lots of experience rooting and modifying phones, but NOT with the a/b structure)
Now i have no service no my phone, but the sims are detected, as during the set up, it shows both of my numbers.
Both the imei numbers are there if i dial *#06#
Unlock was a while back using simple fastboot flashing unlock, and my previous set up was stock, with arter97 kernel & magisk.
I fastboot flashed 2 roms i could find (21BA and 21AA and neither made a difference) - so i'm factory reset too. I'm on Three UK if anyone knows how to get this sorted!

I had the same problem yesterday. Android flashed q, did not work, then returned to 9.5.11, but there was no service.
I reset my device using msm tool. Visit the Msm tool topic, my problem is solved.

You've answered it yourself. You flashed the wrong rom with 21AA. 21BA is for Europe.
As mentioned above, the MSM tool will sort it.

Actually, that wasn't the issue. I've had both on my device before with full functionality. The problem was, when i went back to stock it switched to slot B. was as simple as switching back to A. Now i've updated to open beta 1, i'm back on slot b and all working

Just use MSM tool. There are a few of them in the Guides section. Read instructions in the thread for that MSM tool, which involves installing certain drivers on your windows PC, as well as putting your phone in EDL (emergency download) mode.

i believe that you tick the SMT when flashing using MSM?
if yes, AFAIK you can try to flash using SMT again.

Did this work out? I'm in a similar position with my Oneplus 6 and can't get Wifi or IMEI back.

I have same issue brother no sim wifi baseband unknown

yes bro flashing with msm smt download fixed my problem you can give it a try
once your baseband is fixed than imei restoration is easy

I try to flash whith smt but if give error after some time start flash

Anyone fixed this issue or not?

i flashed a couple times with msm (tmobile version), but this didn't fix my issue of unable to turn on wifi. this msmdownloadtool installed tmobile android 9.0 stock rom which didn't help fixed the issue. i then tried full resets and wipe data. still didn't work. i was going to give up, then i thought just do System Update thru cell data (since no baseband means no wifi). it installed the android 10 stock rom, and fixed the issue. now i have regain baseband and wifi.
hope this help anyone with the same issue

It could be a HW problem with the network IC (very common) but trying SW solutions like flashing first is advised

Question Asus Rog5 imei Null No network

I make a software by QFIL - after that imei null
I Have The Box with IMEI but I don't Know how to restore It ??
there any solution to fix the network?

You need to hex edit your IMEI into your QCN file and flash it back to the device. Also from QFIL.

There are a lot of guides on XDA and elsewhere for the steps. However you need to first secure a working QCN file if you don't have a backup of your own and know the IMEIs in that file, so you can locate and overwrite with your own IMEI. Without that, you won't get far... I don't have a QCN file for this device on hand, maybe someone else here does and an share with you...

Is there a solution to unlock bootloader always Error11003

@Andrologic
Hey! I have been long trying to recover my nulled IMEI on ROG5. Every single tutorial I can find asks for a qcn file along with hex editor to input your box IMEIs. All follows up on my end until I use Qfil to restore a changed qcn file. It only writes till 2% and then phone goes into ramdump screen which means there's some kind of IMEI write protection on device or something like that. Because all other IMEI writing methods fail the phone to same RAM Dump screen. Desperate for some help.
Also there seems to be a problem getting diag mode to work on all stock ROMS. The only way diag mode works is by using ENG factory firmware on my ROG 5 which enables diag mode by default. The Asus_volte_su_fixed apk provided by @twistedumbrella Also doesn't enable diag mode on ROG5.

This is not based on my own experience - but it looks like you may have access to write the IMEIs to this device via one of the ASUS Key partitions - in which case you may (or may not) be able to bypass writing QCN altogether.
I forgot the name of the guy who posted it, I believe it was under a CN>WW conversion guide - try to look it up and give it a try...

The Imei part was mentioned in the very last part of thhis guide:
Repair ROG Phone 5 ZS673KS through edl firmware, no need to unlock Bootloader to modify COUNTRY CN to WW
These materials can only be used for ROG Phone 5_ZS673KS, and ROG Phone 5S_ZS676KS cannot be used. ROG Phone 5S ZS676KS Please see...
forum.xda-developers.com
Someone tried that for a seperate reason and apparently it changed their IMEI:

Now, When I change the asuskey4 file, My IMEI do appear in the bootloader screen but when phone starts, it goes into a boot loop which stays even if I reflash the ENG firmware or stock firmware and ending in RAM dump screen.
Erasing the modemst1,modemst2 and fsg partitions from the phone does allow to get out of the bootloop. But shows Null Imei in the phone, while showing the IMEI in the bootloader screen.

So, apparently if I cannot restore the qcn file, There's no other way.
But Restoring QCN in ENG factoey firmware using QFIL or QPST only goes till 2% and then fails and phone goes to RAM Dump screen. Which apparently means that the phone has somekind of NV data write or IMEI write protection.

Writing QCN via Qfil goes till 2% then phone turns off and then status goes this 164% after which it shows that:
2022-05-05 08:53:19.685 Subscription ID:1 EFS File:/sd/mru001_ext_Subscription01, Function:NV_Tool_WriteNVsToMobile, Event:3 164%
2022-05-05 08:53:19.686 Done uploading the QCN file: C:\Users\mhrs_\Downloads\Compressed\GenericIMEI\patched.qcn, Sync EFS
2022-05-05 08:53:19.687 Done EFS Sync
2022-05-05 08:53:20.689 Reset Phone

2022-05-05 08:53:24.208 Finish Restore QCN
Attached is the log file from Qfil.
After this, phones goes into RamDump screen and when I hard reboot the phone, I can see IMEI changed from Null to 0 but still not my original IMEI :/

using qpst to restore only goes till 4% after which phone gets stuck in Ramdump screen.

Please help me to solve the network problem

Hi, Guys. I have the same problem since few days... Hope we will find a solution soon.

You cannot use others's qcn file to restore your imei. The imei store in fsg, modemst1, modemst2 also in your qcn file. If you use others qcn then they don't match each other, you'll failed to restore. The key: you need to empty the partition of fsg, modemst1, modemst2 in oder to restore other qcn file, but the system is read only so you cant do anything.
