Second SIM isn't working anymore - Lenovo K6 - Lenovo K6 / K6 Power / K6 Note Questions & Answers

After buying Lenovo K6, it was okay with the marshmallow firmware, then I recieved the Nougat update and I didn't really like it, So I installed AOKP custom rom and then I wanted to get back to the stock firmware, which is mm.
I flashed it fine but the second SIM is not working anymore, it says " No service | Orange EG "
It's detected but it doesn't really work, any help please ??

did u checked baseband

i think it is basebend issue..firstly you have to have adb&fastboot on your computer,then plug your phone on computer,open adb and type: adb reboot bootloader(it boots in fastboot),then type: fastboot erase modemst1 and then: fastboot erase modemst2,then:fastboot erase cache and then fastboot reboot..now both sims should work...

@ilia1998, Oh my god .. you saved my life, I don't know how to thank you, trust me you're a life savior!!
Thanks a lot <33333

I had a strange problem with my Lenovo K6 Power. It was working with 4G network only. In my place I have installed 2G network booster for better signal reception but my mobile was unable to get 2G network. I tried various solutions from resetting the phone to flashing older Marshmallow ROM but nothing works. Finally I arrive at this page and follow these steps and bingo! My mobile get full network and become useful once again! Thank you so much...!:good::good::good:

I got my baseband unknown and iemi 0 because of this.
somehow i got someone's qcn file of k6 power and flashed it through QFIL, it had someone else's imei number, then i replaced my imei with something called WriteDuelIMEI application, at first it wasn't showing up COM port then i rooted my phone with magisk, and executed the following commands from adb
Code:
adb shell
su
setprop sys.usb.config diag,adb
and bingo, it showed COM port and I wrote both my IMEI numbers and clicked start, it successfully did put both IMEI numbers but still sim cards were off and no network.
Then on next day, I used Lenovo Moto smart Assistant and flashed again with the instructions from it.
after flashing and rebooting, it was showing both of my sim networks.
Though volte isn't working in my phone and never worked before for some reason.
Still it's good enough to make some calls thorugh 2G or 3G networks.
Hope it helps someone.

Just elaborating the steps.
1. Download & install Moto X Play drivers from moto website (Compulsory)
2.You need to run ADB commands : There are 2 options
a. Use Minimal ADB & Fastboot --- This is what i prefer - as it's hardly 2 MB & serves the purpose.
Link : http://forum.xda-developers.com/showthread.php?t=2317790
b. OR download the entire andriod SDK - which is > 1 GB
3. In the command prompt of minimal ADB, type "fastboot devices" to check for the connected devices
4. If your device is shown, then type "fastboot reboot" to reboot your device to fast boot
5. Then run the commands in sequence:
"fastboot erase modemst1 "
"fastboot erase modemst2 "
"fastboot erase cache"
6. Reboot and put SIM(s) back!
That's all!!!

****Before Step 3 and after step 2, In ADB command prompt, typr "Connect device" to connect first and then check for connected device.
On my OnePlus 2,
I changed the LTE band from service menu, & faced issues w.r.t 2G/3G networks not being recognized.
So following these fastboot commands, resulted in problem with SIM-Slot-2, not recognizing any network, Phone can detect the sim & network though, it just doesn't latch on to the network.
SIM-Slot-1, is working fine though, connecting to 2G/3G/4G.
Any help ?

Can you provide me the necessary modem .zip file !
Nope, because the modem partitions very likely containt unique config data (e.g. IMEI, different for EVERY phone). This is why you should make backups...
Won't help here. Good luck that it's not a brick now...

So the only two working options are:
1. Reflash the modem firmware from fastboot
2. Backup the working ROM partitions and restore if you manage to change the band?
The only options for messing with modem partitions are:
1. Backup your modem and related partitions.
2. MESS AROUND.
3. Restore from backup
Whatever you do, do a backup first. You can NOT recover modem data from stock firmware files.

Thanks for answering. Is the backup/restore solution tried and tested, meaning it's 100% working? Also, does the Partitions Backup app suffice for this?
First rule as always: Your warranty is now void and if you brick your device we'll laugh at you.
I can't say if it's 100% safe; I bet there are devices where you can backup the baseband config data ("modem" etc.), but can't re-flash them as the partitions by definition are protected. So there might be ways to kill them (by using functions that modify them and where you can't directly re-flash them). On my Moto X Play, I can erase and re-flash "modemst1" and "modemst2". But I really prefer just erasing as - to my understanding - erasing only clears certain parts of the config, but does not affect the IMEI data. I would suspect a wrong flash could completely kill your modem and thus render the phone a WiFi only device.
I'd still recommend doing a backup of such partitions the day you buy and root the phone. Can't be wrong.
I would recommend FlashFire as it's doing both, backing them up and re-flashing them.

Getting your device connected is a very important stage, whether it is system,recovery or fastboot. From what I read , you can connsct through fasatboot, since you flashed cyanogen. Just flash TWRP 3.2.1 or so which is the latest, through fastboot:
fastboot flash recovery twrp.3.2.1 .img ( Remember the spaces, the name twrp.xxx.img should be same as you downloaded. If flash is successful, you can see twrp when you boot to recovery. Then flash supersu file and/or whichever rom you want.
Sorry for late answers.
I was lil busy and sorry for wrong address also.
You could get it from firmwarefile.com
I can't post link here but select yu yureka plus variant and download oldest CBP

[solved] Unknown baseband fixed!

I recently ran into the Unknown baseband problem on my G900I. It happended randomly. I couldn't call, and the phone baseband was "unknown" (the modem was failing to initialize). The phone randomly rebooted when the screen was off, and shutdown didn't work (look a very long time and would reboot.)
My attempts:
1. I didn't have an EFS/modemst1/modemst2 backup. Silly me, if I'd had those backups I would have saved a bunch of time! I did a new backup anyway just to be safe (who knows?). Restoring my new backup did nothing (apparently this works in some cases).
2. I was already on stock. Naturally I reflashed stock to unroot, but when that didn't fix it I did a full factory reset. The modem was still not working, so I even went all the way and did a NAND erase all + PIT + clear EFS in Odin. The modem still did not work!
3. EFS Professional could not connect to the modem ("send SPC" didn't work at all, rejected by phone error). In QPST I got "disk error while writing to file" when trying to backup the qcn. In retrospect, these methods probably failed because the modem had been failing to initialize at boot, so these tools weren't able to communicate with the modem. Also note that the Service Mode menu was completely blank, but the USB menu to enable modem diagnostics still worked.
At this point I was close to giving up and about to start finding a mobile phone repair shop who could fix this (I was thinking that I needed a z3c box), until I came across some threads which suggested that they fixed their unknown baseband problem by erasing modemst1 and modemst2. I didn't want to try this because I read somewhere that recent newer Samsung devices stored the IMEI in these partitions, and NOT in the EFS. (don't think this is true anymore...) I had already tried clearing the EFS in #2.
Whilst most of these threads were about non-Samsung devices (they used fastboot erase modemst1, but we don't have fastboot on Samsung), it can still be done in TWRP, see: https://www.theandroidsoul.com/fix-...d-wifibluetooth-issues-restoring-twrp-backup/
After erasing modemst1/modemst2, I rebooted, and WOW my modem now works! SIM is detected!! :good:
So... now I'm confused why people suggest to backup/restore the modemst1/modemst2 partitions in the first place, when erasing those partitions actually solved my problem - and without loosing my IMEI number/BT or Wi-fi MAC! EFS Professional and QPST tools now work as expected. I now wonder where the IMEI number really is stored?
Hope this helps someone!
Notes:
(NAND erase all doesn't actually clear everything. Perhaps there are multiple NAND chips or something)

My issue was a zeroed IMEI on a G900F running LOS 14.1.
I made a backup of the broken EFS first to avoid breaking the poor thing even further. On a rooted adb shell:
Code:
klte:/data/asd # dd if=/dev/block/platform/msm_sdcc.1/by-name/efs of=efs.bak
klte:/data/asd # dd if=/dev/block/bootdevice/by-name/modemst1 of=modemst1.bak bs=4096
klte:/data/asd # dd if=/dev/block/bootdevice/by-name/modemst2 of=modemst2.bak bs=4096
klte:/data/asd # find /efs -exec ls -l {} \; > efs-permissions
And pulled the generated files plus the whole /efs dir. The last command is to keep a list of the permissions in /efs.
To modify modemst1 and modemst2 I used the TWRP terminal. dd complained about no space left. Then rebooted to system and my IMEI was back
Question: what if I have the imei present, but no signal? Because that's my case. I can't get the signal to work on Oreo,:crying:
Thank you!!! my problem is solved!! more power xda team!
I've the same problem on my J7 Prime(SM-610F).
IMEI Unknown
Baseband Unknown
No SIM card detected as a result.
Should I now try all of those above-mentioned methods? Or just follow the last one— erasing modemat1 and modemst2???
I need help, thank you!
I have a 900P, they sold me with a LL 5.01 version, I upgraded in past to Ressurection remix 7.1.2 and the baseband was not working. I solved the problem uploading (after a recovery wipe) the stock 6.01 G900PVPS3CQD1, then TWRP, then wipe again and again Ressurection Remix, than I tried also Lineage OS 7.1.2.
The phone worked for about 5-6 months, than no signal more. I flashed again the stock 6.01 and it tells me "invalid SIM card", the IME is present, also baseband show its version under info.
I flashed than TWRP and typed in its terminal the commands I've found here:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
It saif not enough space but it looks it copied around 3MB. I have no idea what this commands do. I rebbot the phone and nothing changed. Then I continue to read and I typed the following:
dd if=/dev/block/platform/msm_sdcc.1/by-name/efs of=efs.bak
dd if=/dev/block/bootdevice/by-name/modemst1 of=modemst1.bak bs=4096
dd if=/dev/block/bootdevice/by-name/modemst2 of=modemst2.bak bs=4096
find /efs -exec ls -l {} \; > efs-permissions
it looks it did all sucessfully but nothing solved the problem. I'm not a linux expert, I don't know how to copy these backup files to my pc ad eventually look on them, and what to edit and how to upload.
Please someone can kindly write a guide, I see someone has success here, not me, my baseband doen't work. Thank you a lot!!
Hello Friend. I have a samsung g900h, with operator rom, I had battery problems so I made the wipe cache. Question that was left without imei, and flashing a stock rom, still without imei. Could you place the tutorial or the steps you did to solve it? I suspect that I have the same problem, since yesterday the imei appeared for a few hours and then left again. I would appreciate your help, greetings!

I already have twrp, the problem is that now when trying to write the commands in modemst1 I get "no such file or directory". I clarify that I am not root, is it necessary?

If you aren't root you can't do nothing. Or you flash a rootable ROM, or you use terminal in TWRP

I tried also to format mmcblk0p3 with mke2fs under TWRP but it hangs when writing..
Nothing changes, IMEI never lost, sim if inserted is not recognized, but the symbol is different than if not present at all.. so I suppose not an hardware fault.
Tried EFS professional, not working because open box doesn't give find command, but it is activated. I tried really all..

It's strange what happens to me. Now I have a signal, the imei and the baseband appear. The same thing happened to me a few days ago, and then I lost it again. For now I'm still waiting for the imei or signal to go.
I add that I flashed a stock rom last night, but it did not have imei. This morning when I got up there was a signal and I could see the imeil. Rare
No Such File or Directory.

I recently ran into the Unknown baseband problem on my G900I. It happended randomly. I couldn't call, and the phone baseband was "unknown" (the modem was failing to initialize). The phone randomly rebooted when the screen was off, and shutdown didn't work (look a very long time and would reboot.)
My attempts:
1. I didn't have an EFS/modemst1/modemst2 backup. Silly me, if I'd had those backups I would have saved a bunch of time! I did a new backup anyway just to be safe (who knows?). Restoring my new backup did nothing (apparently this works in some cases).
2. I was already on stock. Naturally I reflashed stock to unroot, but when that didn't fix it I did a full factory reset. The modem was still not working, so I even went all the way and did a NAND erase all + PIT + clear EFS in Odin. The modem still did not work!
3. EFS Professional could not connect to the modem ("send SPC" didn't work at all, rejected by phone error). In QPST I got "disk error while writing to file" when trying to backup the qcn. In retrospect, these methods probably failed because the modem had been failing to initialize at boot, so these tools weren't able to communicate with the modem. Also note that the Service Mode menu was completely blank, but the USB menu to enable modem diagnostics still worked.
At this point I was close to giving up and about to start finding a mobile phone repair shop who could fix this (I was thinking that I needed a z3c box), until I came across some threads which suggested that they fixed their unknown baseband problem by erasing modemst1 and modemst2. I didn't want to try this because I read somewhere that recent newer Samsung devices stored the IMEI in these partitions, and NOT in the EFS. (don't think this is true anymore...) I had already tried clearing the EFS in #2.
Whilst most of these threads were about non-Samsung devices (they used fastboot erase modemst1, but we don't have fastboot on Samsung), it can still be done in TWRP, see: https://www.theandroidsoul.com/fix-...d-wifibluetooth-issues-restoring-twrp-backup/
After erasing modemst1/modemst2, I rebooted, and WOW my modem now works! SIM is detected!! :good:
So... now I'm confused why people suggest to backup/restore the modemst1/modemst2 partitions in the first place, when erasing those partitions actually solved my problem - and without loosing my IMEI number/BT or Wi-fi MAC! EFS Professional and QPST tools now work as expected. I now wonder where the IMEI number really is stored?
Hope this helps someone!
Notes:
(NAND erase all doesn't actually clear everything. Perhaps there are multiple NAND chips or something)

[FIX] Phone Reboots Into Recovery Mode & Can Only Be Started From Fastboot

Thanks to xda member @Shooting Star Max for the original post for this solution
If your phone is always rebooting into recovery, and the only way to boot normally is by using the bootloader, follow these instructions:
Some users recommend removing your SD before doing the following as incorrectly formatted SD Cards could cause the phone to boot into recovery instead of booting normally.
1) Boot into TWRP recovery.
2) Plug your Cedric into your computer (which needs to have drivers and fastboot installed).
3) Open a command prompt window and type:
Code:
adb pull /dev/block/platform/soc/7824900.sdhci/by-name/misc misc.img
This will make a backup of the misc partition just in case.
4) Type the following:
Code:
adb shell dd if=/dev/zero of=/dev/block/platform/soc/7824900.sdhci/by-name/misc
This will clear the misc partition. You might get a message regarding lack of space, but it's okay.
5) Your Cedric will boot normally again

I did the procedure and everything went back normal.
I did a backup with the twrp and when I went to restore and go back everything as before, it will continue to restart in the bootloader and I must confirm with the power key to boot the system.
I tried to repeat the procedure but nothing to do does not work anymore.
Some help thank you

As long as you have fully booted your phone before trying again I don't see why you couldn't repeat it
Or reflash the recovery and try again

Make sure adb is connected properly
Code:
adb kill-server
adb devices
Your device should be displayed as connected & should be the only device listed
If it still doesn't work then the only solution I can think of is restoring your stock firmware by fastboot - do not flash the bootloader part of the firmware

Same phone as mine & Iv never had this problem - I use lineageos - try flashing that
Other than that I can't suggest anything else
Thank you anyway. They persistently waited for Lenovo to provide the tools and release the firmware for my model that is currently unavailable.
I've tried all the constructions here, but they all have background noise during calls and fixed gps in over a minute and it's not accurate.
Do you have my own model with the same features?

I have the XT165 running lineageos
No problems with calls - iv changed the build.prop to edit call volume (see my last post in the lineageos thread)
No problem with gps
You could try running these commands in fastboot as this was a fix for gps in past moto devices
Code:
fastboot erase modemst1
fastboot erase modemst2
Okay, now I'm just trying to build stock, if I think I bought the phone, just the time to get home and unlock bootloader and put custom rom, I almost do not know the functions of building stock. Now I see how it behaves and I guess if I install Lineage again and make all the corrections you've suggested very kindly thanks.

Clearing the whole misc partition may be overkill and cause other issues. In the LG threads they currently suggest clearing only the first 256 bytes.

That's cool. Just a thought.
Different OEs put different stuff there, but really no reason to clear it all if only part is the problem.
And one never knows when they might change the usage.
Oh, and masterdex above appears to have had some issue.

It worked for him but then he restored old phone backups - I recommended flashing lineageos from scratch
Nothing to do, I tried again to download Lineage, make a clean installation by deleting all the entries in the TWRP, configuring the phone restarted in recovery, and rewriting the procedure, the result does not change always restarts the bootloader.
At this point you only have to install the firmware from scratch, someone knows where to find firmware stock model XT1675 16gb storage and 2 gb sin ram single sim?

I tried to give these commands fastboot but the result and that when I restart the phone no longer sees the sim and I have to reinstall the original firmware with fastboot. Tried twice the same result, are you sure you have the right commands?
My Cedric is listed on the adb devices code when it's turned on. But if I restart to twrp then it's not listed. Now how can I perform this

It is listed when I turned off the Mtp. But when I give the first command to backup the misc folder I get
[?] /dev/block/platform/soc/7824900.sdhci/by-name/misc: 1048576/?.

Again solved it. I just backed up the misc in twrp itself by copying the misc file to the /sdcard using the inbuilt file manager of twrp. Then tried the second command. It worked like charm. Thank you

Perfect!
Thank you, TheFixItMan! I have an XT1672, Android 7.0 Stock Rom, and I was having this problem after trying the November update via OTA. The correction steps worked perfectly! Happy New Year!
Thanks hope to try this tonight, have you had feedback that this works? Thanks

cant unlock bootloader

Hey there,
so my problem is, that I just cant unlock my bootloader anymore.
I dont know what to do.
The phone just shows the xiamoi logo for one second and then black screen.
Only fastboot mode does work.
Cmd says remote: oem unlock is not allowed. YES I know that I havent activated developer settings but I cant, because I wiped the system and cant do anything. And how to flash stock rom, when I havent got bootloader permissions.
Qfil and so on doestn work either.
Please respond asap.
heya
only you need to change the partition, ONLY WORK IF YOU DONT ERASE THE 2 SYSTEM PARTITIONS (system_a and system_b), to make that you need to follow instructions:
1.- open CMD in platform tools
2.- in CMD type Fastboot getvar current-slot
3(1).-if the CMD say current-slot:_a you need to type Fastboot set_active b
3(2).-if the CMD say current-slot:_b you need to type Fastboot set_active a
4.- reboot the phone typing fastboot reboot, and Ready!!!

Did you try Mi unlock?

You must create a mi account and need to use a chinese proxy to validate registration
I solved it myself. As mentioned I had no OS installed so there was no way to activate developer settings. I couldtn enter edl mode via fastboot so I used testpoint to solve my problem. I then flashed it via Miflash and the phone works now fine :good:

If you can access Fastboot. THIS WILL ERASE ALL OF YOUR DATA
1. Enter Fastboot Mode > Make sure drivers are installed correctly
2. Enter "fastboot oem edl" > > Ignore Error > Your phone notification led should now blink.
3. Use MiFlash to flash the fastboot ROM.

When your phone is in testmode you are able to flash stock firmware via Miflash. Download the stock firmware in the internet just google it.
You have to install Miflash. Open it connect phone in fastboot (testpoint). Then select the downloaded firmware in Miflash and flash it.
There are many videos on youtube how to flash with miflash.
