Hi,
I bought recently a Redmi 2 Enhanced (2 Gb)
Code:
Redmi 2 Enhanced (2Go RAM / 16 Go)
HM 2LTE-CU
Networks: TDD-LTE/FDD-LTE/TD-SCDMA/WCDMA/GSM
Android 4.4.4 KTU84P
MIUI 5.8.20 | Beta
Base band MPSS.DPM.1.0.c7.18-00023-M8916EAAAANUZM-1-all15
Kernel 3.10.28-gf3355b2
It was working well with my two SIM cards (Free Mobile, France ; Mobinil, Egypt).
I installed Cyanogenmod 11 (cm-11-20150829-UNOFFICIAL-hm2014811) and gapps (gapps-444-base-20150818-1-signed).
It changed also the recovery for CWM recovery.
It worked fine, but the two SIM's are now flagged "No service". If I try to call a number, the phone asks me to switch off the plane mode, which is already switched off. I switched it on and off back, without any result.
I found a similar problem on this link: /thread-125218-1-1.html on forum en.miui.com
He says: "my redmi was working fine but then accidently my recovery was flashed by cwm recovery so I have flashed my phone with China ROM LINK V6.5.3.0.KHJCNCD because global rom is not working, my redmi is 2014813 so global rom does not works and Now I have got my MIUI recovery back but my both Reliance and Airtel SIM are not working there is a message in both tower NO SERVICE."
He says further : "My problem is solved I flashed my recovery with twrp 2014811 version then installed the latest global rom everything is working fine."
I tried it: installed twrp 2014811 and xiaomi.eu_multi_HM2014811_5.8.20_v7-4.4, without getting back my SIM!
I finally used MiFlash to bootflash my phone with wt88047_images_V6.6.4.0.KHJCNCF_20150721.0000.5_4.4_cn_159a7e83ed.tgz.
And the problem is still there: I have no service anymore on both SIMs!
Any help?
Thanks,
Remi
Solved by using wt86047_images_V6.6.4.0.KHJCNCF_4.4_cn image
1. Delete lines 10 and 11 in file "flash_all.bat" (lines containing "*MSM8916").
2. Flashboot with flash_all option.
Hello
I own this phone for 1 year, botloader is unlocked officialy, ihave rooted it and istalled "Nexus Experience 11.0 for Redmi Note 3 SD [7.1.2r24]" and it worked perfectly,
last week i flashed Nitrogen os oreo, i had no issues . But last thursday, i realised that i had no service with my phone, iflashed again the rom and last firmware , but after this my sim card wasn't detected, My imei are ok.
When i want to call anyone, phone says "turn off airplane to make a call".
I spent all my week end on it, i flashed last fastboot rom with miflash, dev and stable, i even flash new qcn.
If anyone has a good idea thanks.:crying:
sorry for bad English
this is based on my experience , i am not a developer
I Am Not Responsible any kind problem, hard brick, soft brick, or any kind of problem
Just for knowledge sharing
Because of new rule of 35 rs recharge on every network provider except JIO, I want dual 4G so that i can run 2 JIO sim in which one will standby number but it is not possible in redmi note 4.
So i found some news/thread on internet about mi A1 that after latest PIE update it began to support dual 4g/volte (i was not sure about news) because MIA1 also run on same chipset snapdragon 625
So i take risk and thought that i can revert to normal if any problem occurred .
I downloaded MIA1 pie rom extract its preloader.bin and found non hlos.bin
then i flash mia1 ( Non hlos.bin) through fastboot on redmi note 4
i was in superior os ( pie) then i rebooted to system and no network showing , basenband known, IMEI1-0, IMEI2-As it was, but no network. so i again flashed original redmi note 4x Non hlos.bin then rebooted but this time phone not booted and boot loop occoured
so i wiped out every thing including internal and clean flashed superior os rom through orange recovery, but mobile on boot loop
So i flashed miui recovery rom and activate through wifi booted but no network, sometimes its shows both IMEI present)some times 1 IMEI ((without network on both case), also code (*#*#4636#*#*) radio on-off continuously and sometime always off ,tried ON but not success.
I did't have any problem on wifi or Bluetooth
Again flashed custom rom but any custom rom not booting
Flashed miui through FASTBOOT , EDL IT was booting but network not coming.
Also tried this methodhttps://en.miui.com/thread-545300-1-1.html and restore .QCN then write original IMEI but problem not solved
i found that when tried command on minimal fastboot fastboot erase modemst1 and fastboot erase modemst2 each time fast boot gives error remote partition not allowed tried platform tools also.
also tried to delete files from efs explorer of qpst tool .
then i downloaded mfastboot
and run command
mfastboot erase modemst1
mfastboot erase modemst2
and surprise its successfully done then i booted to miui enter to diag mode and restore .qcn and write my original IMEI and after reboot wow both SIM network back , checked base band , radio , IMEI all normal.
flashed custom rom and its booted normally and not faced any network problem ,wifi problem.
and problem solved
if this thread helped any one who is unable to solve network problem just by restoring .qcn or by anyway please press thanks
I did not understand everything, but to avoid this problem can simply be avoided by flashing the rom which is compatible with your device.
So, if you have a Xiaomi Redmi Note 4x and flash a rom which is supposed to be installed on the Xiaomi A1 or vice versa, then can you be so happy that you now aren't the proud owner of a quite expensive paper weight.
It isn't enough that you remove/rename etc two or three rom files or both are sharing the same CPU.
Most important is to avoid making the same mistake or a similar one and to learn from it.
And of course that quite pricey paper weight dismissing
Hi, I've done sth
I had cleaned my xiaomi redmi note 9s EFC files without taking back up. Then, I changed phones IMEI (Just slot 2 based on methods on this website (https://cookkolay.com/xiaomi-redmi-...-ve-tek-sadece-burada-note-9s-imei-tamir.html). But my phone did not find any signals. I tried *#*#4636#*#*, but it had no use.
Again, I write xiaomi redmi note 9 pro, It find the the signals, however after 10 to 15 minutes, it repeatedly turn off and on the signal power . Also, phones WIFI did not work properly.
please help me,
If it is possible for a kind person, please send me a back up of one efc, so I recovery my EFC, then change its IMEI.
Thanks for your help in advance.
Update :
By flashing only the IMEI 2 I can make the LTE work on the engineer firmware but when I flash a custom ROM PE, EvoX, LineageOS (after a flash of the latest global firmware):
If I manually flash the modem firmware MOLY.LR13.R2.MP.V16.P21 the SIM is not reconized and IMEI 1 and 2 are unknown.
If I leave the modem done for the ROM the SIM is recognized but no LTE, phone call, etc
So... it's still not really solved, I found this solution on treads for the redmi note 9 https://forum.xda-developers.com/t/...nally-first-method-to-fix-1-slot-imei.4258977 and https://forum.xda-developers.com/t/...-in-merlin-redmi-note-9-redmi-10x-4g.4258779/
The PE Rom of the redmi note 9 is visibly compatible with the engineer modem and that's probably why it works with this phone but not the redmi note 11S.
Original Post :
Summary:
I can't get LTE or 3G to work, I tried with several SIM cards that work on other phones.
The problem happened after a formatting and then a complete Flash of the phone with SP Flash Tool to get out of a Hard-Brick.
Issue:
With the Miui ROM, the phone starts directly in recovery and displays nvdata corrupted (doing a "Wipe data" doesn't change anything).
I tried to flash the nvdata,nvcfg,nvram,proinfo,persiste,protect1,protect2 of another Redmi note 11s with mtkclient I manage to start but the SIM card is not recognized and the modem is in unknown version.
On the engineer rom by not flashing nvdata, nvram, etc the modem is in the right version but there is no IMEI and I have no access to the internet and can neither make nor receive calls and SMS.
On the engineer firmware with Modem meta I can flash the original IMEI and the calibration parameters of LTE, WCDMA and GSM retrieved by myself from a redmi note 11s on which the network works with the engineer firmware as with MIUI and after all that I can receive calls but not make any, I can have EDGE but not more and the settings continue to mark "no service" and "radio off", the IMEI and correctly displayed in the settings and when I accept a call the HD logo is displayed, the VOWIFI works and allows to make, receive calls and SMS, note that the serial number displayed in the settings does not seem to be the right one, Everything else works.
On a custom ROM it is identical to the engineer rom.
Context:
My phone ended up in a Hard-Brick following a problem in the unofficiall pixel experience custom recovery (impossible to access fastboot, recovery and system after an "adb reboot fastboot" but Brom mode is accessible).
I used mtkclient to disable the Brom mode protections, I then flashed the firmware V13.0.3.0.SKEEUXM with SP Flash Tool but by ignorance of the software I used the "format All + Download" mode (which has the effect of formatting all the partitions including nvdata, nvcfg, nvram, proinfo, persist, protect1, protect2).
Then I was able to boot but the phone enters directly in a bootloop with nvdata corrupted which is displayed in the recovery, I tried a data wipe but it does not change anything, I used mtkclient to reunlock the bootloader and make the tests that I described in the problem part.
The phone is under warranty but I had unlocked the bootloader, the problem being due to this unlocking, the phone will certainly be considered out of warranty and if they follow their policy in french they will not repair it and the shipping will be at my expense.
After unlocking the bootloader with mtkclient:
I flashed V13.0.7.0.SKEMIXM, flash the unofficial custom rom of Pixel experience 13 with its boot.img, reflash the nvram, nvdata, nvcfg, proinfo, protect1, protect2 from my phone when there was "corrupted nv data" and wipe data with custom recovery.
Pixel Experience works really well, The SIM card is recognized, it shows my operator, baseband version but there is no 4G, SMS and IMEI, IMEI SV is unknown.

There is no way to do it without hardware tool ?
and I don't really understand what you are talking about, can you give me more detail ?
@tutibreaker I updated the original post you could read, even after flashing the IMEI with modem meta there is still no 4G volte and SMS whether on the engineer firmware or the firmware V13.0.7.0. SKEMIXM with pixel experience, SIM and operator detection, baseband version, IMEI, phone number works as it should.
I don't know enough about meta modem to know which option/procedure would make 4G, volte and SMS work again.
nvram, nvdata, nvcfg... from my friends redmi note 11s still doesn't detect the sim card and meta modem can't connect with.
I really need some help please.
I updated the original post again (and again), If someone could help me it would be really nice.
To summarize now I managed to restore the LTE on engineer firmware but not on custom ROM (PE, EvoX, LineageOS)
I have the same problem you can flash gsi but use gsi is sucks
Did you manage to fix it?
