[Q] Help repairing my IMEI with QPST and EFS Professional tools

Hello again folks,
I opened another thread regarding this problem I have, but since no one replied, I did some research and made some progress. Here's what happened: my cousin bought me an gt-i9301i in the UK, made a 5 min call or more with her SIM as instructed, and sent me the phone here in Brazil. When I received, the phone asked for the SIM network unlock PIN. I tried to unlock it by myself, with no success. Before sending it to a local store to try unlocking it, the only things I did were flashing a Chain Fire rom to root it, and then flashed a Stock rom to turn it back to its original state before sending it to be repaired. The store "unlocked" the phone, but now my IMEI is gone.
In the last days, I'm trying to fix it using QPST and the EFS Professional tools, as instructed in this thread (http://forum.xda-developers.com/gal...warning-guide-backup-restore-imei-nv-t1946915) and also this external tutorial (http://droidmodderx.com/galaxys3/?page_id=79).
I did the following procedures on my phone using its stock ROM, with USB debugging on, and tried with both root access turned on and off.
This is what I achieved so far: I connected my phone to QPST (by the way, the working code for my S3 Neo phone is *#0808#), and after turning on the RNDIS + DM + MODEM mode on, made a backup using the "Download" QPST tool. I tried to edit that backup (the file has about 260 Kb) using the "RF NV Manager", as instructed in the second post I mentioned, by going to the item 550 and writing my IMEI in blocks and everything, and then creating a separate QCN file. When I try to restore the new file using the Download QPST tool, which supposably has my IMEI number on it, I receive the message "Received an invalid command from the phone" at just 1%. When I try to restore the original backup, it goes to 100%, but in the end, I receive the message "Could not Reset the Phone. Communication Errors Occurred". When I try to edit my IMEI directly on the phone, when I reboot it and turn it back to MTP + ADB, my IMEI is still showing nothing.
Using the EFS Professional Qualcomm NV Tools, when I try to write my IMEI on the phone, using the Secure Ops. tab, I recieve an error message saying NV_ERR_BAD_SECURITY_MODE, and when I try to edit my QCN backup, I receive the message "Unable to write selected byte data to QCN Backup!".
Any thoughts on what else can be done to restore my IMEI?
Thanks

Lenovo k6 note baseband issues

Hi everyone
The last week i updated OTA nougat on my lenovo k6 note, and after that i lost my connectivity (4g/3g etc).
To try to restore my phone i downgraded (flashed) 2 stock firmware:
- a wrong stock rom ( lenovo k6 k 33 my mistake...)
-After that i flashed a correct version K53_S123_170216_ROW_QPST via qfil, and then i manage to recover the dual SIM IMEI (just typin the IMEI number in my k6 note box) with this tool (qualcomm-smartphone-write-imei-tool-v1.01) via diagnostic menu , but the connectivity wasn't restored completely.
- In about device it says : Baseband JO.1.2.c2-00099-8937 unknown.
-The Sim 1 detect 4g but i can't enter to internet and it can't make calls. but it can receive calls and SMS.
-Same as for SIM 2, it can receive SMS but can't make calls.
I tried to do the following:
-Re flash stock firmware, and make a hard reset (didn't work)
-i made a xQCN backup from other k6 note, and i reflashed with qpst and changing the IMEI didn't work.
I don't know what else do
Thanks in advance for your answers.

Sorry i cant help you but let me tell you what i did when i faced almost the same problem.
I am a lenovo k6 power user (k33a42). After upgrading my stock rom to latest nougat update through OTA my device went into bootloops. Unfortunately i had no backups so i reflashed the stock rom. The device started working again but then i found out that both of my SIMs were not working (No sim indication, no IMEI number, no network). Tried everything i could but later decided to give it to the customer care as it was still in warranty. It took them 4 weeks (4 WEEKS!!!) to fix the device and later told me that the motherboard was faulty. So if no methods work out for you, my only advice is to go to the customer care if you still have the warranty.

yes, i still have warranty, but first i need to know how re lock my bootloader before giving it to customer care .
Thanks for the reminder i didn't consider that option.

Oh thats simple if you have proper drivers (ADB & FASTBOOT) installed.
Just boot your device into fastboot mode. Connect it to the PC and type this code in cmd:
"fastboot oem lock" and press enter (without quotes)
The device may restart but if it doesn't just type this code:
"fastboot reboot"
If everything goes fine, reboot the device to bootloader again and check the bootloader status by typing this line in cmd:
"fastboot oem device-info"
It must say that "bootloader unlocked: false"
Done!!

EDL mode

EDL (Emergency Download) Mode has been removed/ disable from MIUI 8.1 onwards and Redmi 4A later Xiaomi devices. So you can flash MIUI Fastboot ROMs on your device by using Fastboot mode only, if your bootloader is unlocked. And, we can't use Qualcomm Jig Cable(s) also now.
So, we have only one way to know Qualcomm HS-USB QDLoader 9008 port from PC. It's Test Point Method. This method will work with every MIUI ROMs (Upgrade/ Downgrade) , Locked Bootloader/ Unlocked Bootloader and also work to recover from a Dead boot device (Bricked).
While touching these two points with a metal tweezers plugin the usb cable to the phone and PC will make the phone enter edl mode. You can then release the tweezers.

Bro edl mode is not removed. It's just moved to fastboot. You can enter edl easily by "fastboot oem edl" command. Hope this helped :laugh:

Thanks for the explanation, in any case tere can be situations that fastboot it's not available, hard but possible, in that case that info is helpful...

In any case, the bootloader muz be unlocked to initiate EDL using ADB fastboot..

What makes you think I'm so lame as well. I have used this command and flashed my mi max 2 with fastboot rom. Tho I don't remember if bootloader was locked or unlocked. Probably it was unlocked. But still no issues as anyone can unlock thier bootloader officially.

i wasnt intended at you. it seems they forgot some ways when they first deployed the edl blocking access but with the most recent "roms" they have blocked every access way to edl when bootloader is locked : adb, fastboot & cable
the only way left is from internal pins, but we can expect they will hide them even better on new phones.
Today it's much worth to wait 72h (+30days if you just already unlocked another one today) than opening the models that have "non removable" batteries and risking to leave traces/damages
it's really a shame that xiaomi lock their phone this way, it's a very bad message at the users (fastboot is so much restricted that you cant even switch between stable&dev anymore with locked bootloader) but we still have the chance that they allow unlocking and that this unlocking is a real one allowing full control

Fastboot rom isn't needed untill we brick our device and we can't brick the device untill we have unlocked bootloader. So basically edl mode will work when it's really needed.

It doesn't work for my MM2. Got it since 4/12/17. Didn't know i need to login to mi acc to register my device, set usb debugging, developer's mode, unlock status...I had the phone for less than 2 hrs after updating to MIUI 9 from ver 8 (using the updater app) before it suddenly froze up, crashed and went into bootloop. I tried contacting xiaomi svc ctr but those clowns refused to help saying my device is china export.
I cldn't even get them to help me register my device on my mi acc using the imei & s/n info. So if anyone could offer some suggestions as to how I could ressurrect my phone, I wld be most grateful. Failing which the only avenue is to bring it to a svc ctr in China to get them fix it.

My test points don't seem to work
I opened up my mi max2 and followed the steps to short the testpoints but my pc doesn't seem to pick up the Qualcomm device.
Anyway to trigger the thing so that the Qualcomm device can be detected?

I managed to short the test points and got the Qualcomm HSB device on the device mgr, flashed the mi max2 with the latest global stable (V9.2.1) rom. But the phone is still stuck at the Android logo with 3 dots...
I wld have thought EDL flashing wld have wiped out everything on the phone and start afresh?
I am now thinking of formatting the entire phone and reflashing it again. How wld I do that?
Thanks for any inputs.

Hi, Does EDL with test point flashing refresh the boot partitions?
I have shorted the test points and successfully reflash the phone with the latest stable global ROMs (even back to MIUI 8.5.6) but just couldn't get the phone past the MI/Android logo after restarting it
If the boot partition files have been messed up and EDL flashing is not refreshing these files, no matter how many times I try to EDL flash the device, it's not going to help. Pls correct me if I am wrong.
Any other options I can try?

[H870] com.phone.android stopper working and serial number lost

Dears, I hope someone has any idea about what I can do...
Yesterday I had the G6 with fulmics ROM installed. I tried to make a factory reset with TWRP to clean everything was fine but I was not able to get out of the recovery. I was stuck in a recovery bootloop...
I tried this command from another thread:
Code:
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/misc
and I was able to get out of recovery, but now I was stuck at bootloop with the message "Your device is corrupt"
I let the battery discharge completely then I pressed UP button and inserted USB to my PC and I was in Download Mode.
With LG UP and Uppercut I loaded the image of the stock firmware I was having before and now the G6 is booting correctly when I have no SIM card inside.
If I put the SIM Card the process com.android.phone stops working continuously and I cannot have network connection...
I browsed the phone informations without SIM Card and I still have the correct IMEI inside but, the IMEIsv is 00 and the S/N of the phone is empty...
So, do anyone have any idea of what I can do to have it working back again?
I cannot unlock the bootloader again because the unlock.bin is related to the IMEI and S/N and one of them is gone....

Authorized service should repair it free of charge. By the way, tempering with S/N etc. is illegal and not supported by this community.

oh good, I was thinking I destroyed it completely. Tomorrow I will bring it to the LG service. Thank you!
