ZTE L6 stock rom/baseband?

Hey,
anyone here with a ZTE Blade L6 and a running (stock) rom? I bricked mine using some chinese adware-root. After flashing a described as "stock" rom firmware image, i had the phone up and running, branded and netlocked by Digicel. With a little dirty work i now have it mostly unbranded and with another modem even online.
Now, my problem is the modem/baseband. Some give me emergency-calls and a working data connection (but only GPRS/Edge), some even the ability to make phone calls. BUT: I never got back the 3g/wcdma. The Mediatek Engineering-Mode tells me, its using the bands 850/2000(2100), 900 is grayed. As i am in Germany, this should be the issue.
Is anybody in here, who has a working L6 rom or knows how to unlock the wcdma-900 band?
My NVRAM doesnt seem to be changed, my IMEIs are still there..
Thanks in advance!
"Even if it was unlocked, your antenna wont do it!" isnt the right answer, it did before so why shouldnt it now? And its just 50 Mhz..

Same here, I need the real stock ROM or a working C-ROM for the ZTE Blade L6, not the Digicel FW. My phone has been "SIM-slot is permanently locked" after inserted a Sim Card which wasnt supposed for this ROM/Provider, it seems.
I would appreciate it if someone has the S- or C-ROM or knows how to unlock the permanently locked slot again. OEM Bootload unlock (via ADB - I needed to confirm the OEM unlocking with the Powerbutton on the phone but it doesnt react) and ReInstalling the Digi-ROM wasnt helpful.

I unlocked mine using the modem of the L5 Plus-rom. The modem goes to emergency mode every few minutes and data isnt working good too (no 3g, even though i fixed the bandmode somehow), but it gives you a little bit connectivity.
Just grab the L5-Rom, mount the system-images of the digicel-l6-rom and the l5 and replace the modem in /etc/firmware with the l5-one.
You can flash the L5-system too (only system, nothing else!, at least NOT the boot.img). But for me it shows a data connection but cant use it..

Nice, as soon I have time, I will give a try on this. :good:
Addy:
Like said, doesnt work properly. :/ Crashes and disconnect. Well, it´s just my fun-phone to test out some roms and recovs, so it´s not that important.

Ok, since I´ve managed to revive my "playphone", I´ve made a fastboot-flashable nandroid backup. It includes also i.a. a custom recovery from TWRP in an extra-folder.
If someone just need the custom recovery w/o loading the whole ROM, click the 2nd link.

Phone Radio NOT working/turned on with converted Axon A2017 to Axon A2017U

Hello, first of all I want to let you know that I am not an expert but have so far been able to convert my Axon A2017 to the US A2017U version.
Big thanks [email protected] for supplying the necessary files.
I have:
-unlocked the bootloader
-rooted the phone
-flashed successfully B20
However, When I upgraded to B29, I lost TWRP and the cell radio of the phone is non-responsive. It won't even turn on. Bootloader is sill unlocked. I made phone calls on my T-mobile network when it was the origional A2017 B8 version. So I believe the bandwidths are compatible.
I have already done the following troubleshooting: (note: WIFI currently works just fine)
-My network is with T-Mobile, and I have been using a different axon A2017U for over a year with no problems.
-When I type *#*#4636#*#* and got to phone Info says, GSM Service: Radio Off, and the Turn on Radio button does nothing.
- I have tried working with every setting in this menu with no luck.
-When I insert my SIM card that is working on my current axon 7 into the converted A2017U, it is able to pick up T-Mobile network u.s. LTE, (fast.tmobile.com) and T-Mobile US (tmus). However, there are no bars because the radio is not turned on.
-When I try to search for new networks an error message saying, "network search cannot proceed when the data service is enabled disabled it?" So I disable it and nothing happens except for an error message saying "error while searching for Networks".
-In network mode I have switched to every option available, LTE/wcdma/GSM, wcdma/GSM, and GSM only with no result.
I am currently running Android version 6.0.1 on build B-29. Any help to get the radio up and running to receive phone calls would be greatly appreciated. Everything else is working except for the phone radio to send and receive phone calls.
Thanks for any Help.

Do you still have your IMEI or did the partition get corrupted?

I check the number with several online checks, as well as T-Mobile, and they are unable to bring up any information about the number. I imagine it got blocked or corrupted during the upgrades.
What do I do to unblock it or make it functional again?

Go to settings>About>Status and check your IMEI number. If it's blank its noyt gonna work on any network...
You might be able to restore it if you have a backup of it - no-one will give you their backup as you then have their phone - or as a last resort, you might need to restore to the stock Chinese Rom again and see if that fixes it...
Good luck, I'm off to bed after a long backshift...

Thankfully the numbers are there on both IMEI slot 1 and IMEI Slot 2. Thanks for your help. I hope to hear from you after a good night of rest.

Flash the correct modem/bootstack for your device.

Will I need TWRP to flash it or can is just use the Reg. recovery system?

You need TWRP. Just install it with axon7tool via edl if you don't have fastboot, or try axon7toolkit

Here's the latest update:
I loaded TWRP onto the phone and installed the file A2017U_N_Modem.zip. (Several Times)
nothing has changed. The radio is still turned off and no signal is being picked up from my carrier T-Mobile.
While loading it says: Loading A2017U_N_Modem for nougat system. I am not running nougat and I cannot find any other modem to download. Will that make a difference?
Any other suggestions are welcome?

Okay it works! I've got signal but when I try to make a phone call and my other phone picks up I can't hear or say anything. Any idea what's happening? I have tried refreshing the signal with no luck.

Hey man, I'm having the same problem with my Axon 7, brand new A2017U. Turned it on for the first time and I haven't had an ounce of radio on. Same things you've tried I've tried and it refuses to work. Mine is not rooted and I don't want to. I've tried downgrading my update and to no avail. Factory reset etc. I've contacted ZTE and they said they have forwarded my details and my phone details, storage size, color etc. To the necessary representatives. I think I'm gonna be sent a replacement, but just wanted to let you know your not alone.

No network access (Moto G5 Plus)

Hi everyone,
I've been having a problem since yesterday morning. Everything seemed to be fine with my phone before I flashed a custom rom. I was using at the moment MSM Xtended and I flashed the latest version of CrDroid. After flashing that other custom rom and booting, my phone had no network signal. All it reads on the status bar after that is just "No service". Of course, I removed the SIM card and reinserted it many times but that did nothing.
I've already tried flashing another rom (the latest AICP rom) and even going back to the one I was using at the beginning, but still nothing. I even tried reflashing the NON-HLOS.bin file and erasing modemst1 and modemst2, but it didn't do anything either. I also tried flashing this deodexed stock rom and booting. Interestingly, that kind of fixed the problem, since it recovered its network functionality. However, after reflashing an Oreo custom rom, it loses it again (actually, I've done that a few times today, but the last time I tried flashing the stock rom, for some reason it didn't fix it anymore). I don't know if in this case it's worth mentioning it, but I've tried checking my IMEI on both, custom roms and stock rom, and it's never been 0 at any moment.
TL;DR: My phone lost its network signal after flashing a new custom rom and I have no idea why. If anyone could somehow help me, I'd be really, really grateful.

I have had this happen so many times it is not crazy LOL. The best you can do is find a rom that it happens the least. For me it has been AOSP extended. Signal has been great. It is a bug that I dont think the devs even thought would happen with 8.1 roms. It will happen to everyone at some point if we stay on these 8.1 roms i guess until we get a workable 8.1 stock rom. There will be those who chime in saying it nevver happen to them but it will eventually.

Well, it's nice to know I'm not actually the only one then, I guess. But is there nothing I can do? Since I can't seem to get it fixed even by flashing the stock ROM anymore and flashing AOSP extended didn't seem to help at all either

I know brother there is no rhyme or reason it just happens. I am hoping when 8.1 stock comes out for us there will be a new batch of 8.1 custom roms without this problem. Right now i am on extended and havent had any signal problems for a few weeks so who knows.

Okay. Luckily enough, Oreo stock ROM doesn't look like it's gonna take too much more to arrive... Or so I hope, at least. Thanks

I was using LinageOs and it was working great. Then I decided to install DolbyAtmos and for that I flashed Magisk . Suddenly i had no network but my sim cards were detected , IMEI was there but no network on either sim whatsoever. I tried reflashing the LinageOs and PixelExperience ROM but none worked. So I tried flashing(ADB) the stock firmware only to lose my IMEI . After reading this post I tried Debloated ROM and my network was back. I should have stopped at that point but I tried to return back to stock again and lost IMEI again and now I have tried Dbloated,LineageOs , PixelExperience , AOSP Extended , but none helped me getting back network . Now I am stuck with this phone with no network , I had a backupp of my system before I flashed Oreo ROMs (with EFS) so I can get IMEI back but no network. This phone was my daily driver and now I have no idea what to do.

Everything you said is exactly as if I had written it. I did all of that and now I'm exactly in the same position. No idea how to fix it yet. Still, if you managed to find a solution somehow, please write a reply on this thread again

No success yet , but read on some posts that different baseband could be an issue.

Solution I've tried and worked 100 %
Hi bodies,
You can turn off your phone,
Go to fastboot menu by pressing and holding power button and volume down button in the same time.
Roll to "Restart Bootloader" with volume up/down and validate with power button.
Now select start and the network is back.
see you !:fingers-crossed:

Hello everyone I am facing signal problem with my moto5G plus device .it detect sim card but not getting signal . While searching manually it's say's error while searching network. When i checked in QCQM app for sim card test it's shows " PHONE ICCID Compare with SIM ICCID: ERR". Can anyone give me the solution .. I have tried to boot device in bp tools mode it worked for me only ones until next reboot after that nothing is happening even bp tools mode also ... Had done restore factory many times but same result with no signal

Hi, i did a clean flash and installed android 11 from android 8.1 on my Moto g5 plus(XT1686), after flashing rom with android 11 i am not getting and network coverage, it detect the sim card but no network, cant even search network manually shows as Not available. But after i recover and come back to 8.1 network works fine. Only after updating to any android 11 it dont work. I tried network reset and even Bootloader but nothing seems to work.
Does any1 knows any fix for this?
Does gapps can effect the Network?

Hardware Issue: Moto G5 Plus not connecting to network

Hi All, I have a Moto G5 Plus XT1686 from India. Since yesterday, the both SIMs don't register with the network, even if it does register I am unable to make./receive calls nor messages. I had tried Network reset, From Phone information changed settings to LTE/WCDMA even Factory reset. My phone is still boot loader locked. Anything I could do to reset the phone to working state, before I could get a new SIM. I dont have another phone from which I can check if this is a SIM problems, however I am trying to check that as well.

Just before installation, while the notification came up. Oreo seems to work fine, finally narrowed it down to the SIM connectors, so need to get that replaced.

I had the similar issue after oreo update. When i checked *#*#4636#*#* in phone info it showed radio off.
I solved it by flashing modem from the Oreo flashable zip of Soak test 1 and everything is working fine now.

Baseband not found [XT1766 SPerry/Boost Mobile]

Somehow or another I have managed to screw up my modem on my SPerry XT1766 (Boost Mobile).
I only get Emergency Calls Only radio signal, Settings app and bootloader info shows Baseband Not Found or Unknown.
I tried using RSDLite to flash
XT1766_SPERRY_SPRINT_7.1.1_NCQS26.69-64-10_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC
which contains the fsg.mbn and NON-HLOS.bin files, but this doesn't seem to help. I've tried multiple firmwares with multiple different modems and nothing seems to be getting my modem up and going. Back when I originally updated I flashed the partition updater also. I have no idea what to do now. I'm downloading the 69-56 version to try that, but I doubt it'll be any different. If anyone has any idea on what to do that would be great. Thanks

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

@Knuxyl
Are you on Boost network? I've seen the radio off problem with ppl using a different sim.

Yeah I already tried that but it jept giving me an error saying unknown command [ ]] or somrthing along those lines. i looked through the script and didnt see any typis. i think your NON-HLOS.img is different format than the NON-HLOS.bin files found in the stock firmwares, plus it's much larger. Anyways, tried a fastboot flash the modem with it and that didnt work either.

No I am not on a boost network but this problem goes more into firmware than network compatibility because the bootloadet itself isnt even recognizing the baseband. For the record I am still using a CDMA network like boost (Verizon)

Also as an update, the 56 version didn't fix it either

The latest update did that too many people. It won't work with a different sim. The radio will be off.
I bet if you put in a boost SIM, it would pop right on.
They changed something in the -8 firmware.
One guy building ROMs (not here anymore) made some changes to his build that got certain networks to work on his ROM.
He never got the chance to share exactly what he was changing.
It seems that if you booted the phone ever with the original sim inserted, it tripped a qfuse (of sorts) and it seems they have added a way for that particular reading to turn off the radio completely if you're not using one of their SIMs.

You are 100% on point. Sprint (and its subsidiaries) had Motorola Mobility to include code in an OTA update which would disable functionality of any network other than the original UICC (SIM). In other words, when you got a new Sprint compatible xt1766 (Sprint, Boost or Virgin Mobile), opened the box and booted the device with the preinstalled SIM in it, the xt1766 became forever locked to that network -- the OTA update carved that in stone. The update made it impossible to downgrade the baseband radio, killed all GSM functionality, and broke the radio on custom ROMs (the latter being unintended most likely). The only people I have heard of getting around this are the ones that didn't take the -8 OTA update. Like you were saying, I'd like to know what Jason M. done in his custom ROM to fix radio function, whereas at least the radio would work with the original SIM on a custom ROM. He said something about "adding missing symlinks" to the build.

I did this too somehow. I think this might bring your baseband back (it did for me), but... well, I'll get to the "but..." Anyway, Boot to TWRP, mount the Persist partition, then go to terminal or pull up an ADB shell and do:
chmod 0700 /persist/rfs/msm/mpss/datablock/id_00
Click to expand...
Click to collapse
Reboot with a SIM card inserted and voila, you maybe might have a baseband again. Hooray! Except in my particular case, I regained a baseband and then somehow lost an IMEI. Well, not really "lost," it's still there when I pull up the barcodes page... but on bootup it thinks it's 000000000000001. I still haven't ever fixed it, though I did manage to turn it to a single 0 somewhere along the line. Fkit.
But I don't know of anyone else who's lost their IMEI this way, and it's been too long ago and I've tried way too many failed fixes to remember what else could have triggered the problem to start with, so who knows. If you decide to try it, definitely make a backup of the Persist partition before you do anything...and make sure your backup turns out to be good first, not corrupt like mine turned out to be....sigh.
