Hello, currently I have a Lg gt540f from a friend. He requested me to change the OS to CyanogenMod. This is a mexican phone, from the company Telcel. He wants to free the phone in order to use it with other carriers.
I already flashed ClockworkMod Recovery 2.5.1.8 and CyanogenMod 2.2, I think this is the 6.1. However after doing this I keep getting no cellphone signal at all. I changed the APN to the carrier's one and the issue continued. I've changed Sim cards, and tried them on different phones and they all work, except on this one. This makes me think the problem is the baseband I have on this OS. So I upgraded to CM 7 with the same result. After doing this I cleared the Dalvik cache and reinstall the ClockworkMod Recovery 2.5.1.8 and CyanogenMod 2.2 downloaded from a different link, but issue continues.
I've read about this on other phones like Motorola Droid, and what they do to fix this issue is to change the baseband to telus or argentina personal. Both of them are quadband with 850/1900 that I need. They do this by loading a Recovery name Androidiani, however I haven't been able to find it for this cellphone.
Is there another way I can change this baseband?? And could you help me a little explaining me the steps? I'm actually new at playing with Android phones and flashing them.
Thank you for your time.
Hello, I found the answer to my problem.
Actually the cyanogenmod I'm using is band compatible with the phone. This is because this CM version is quadband which includes the bands I needed. My problem was actually that I thought that by flashing a custome ROM I will be setting the Radio into S-OFF, automaticly unlocking my carrier phone restrictions. But I was wrong. Some Android devices you can just flash a new kernel, gain temp root access and swith the carrier radio into S-OFF, however this phone is not the case. To erase my carrier restictions I had to purchuse a unlock code and insert it on the phone. This is done with the IMEI.
Thank you for your time.

Ok so I been trying to unlock my phone to use it with gosmart, so I have been flashing all types of stuff to my phone lately so I'm not sure what caused it but I have no sound or Google now or youtube anything that requires sound to function. Google now and YouTube open but trying to search or start a video doesn't work.
Tried flashing all types of ROMs to fix it to no avail. Also failed at getting it to work on go smart (T-Mobile mvno) as well. How do I fix my mic and sound problems? Also while I asking, since they all have the same hardware why can't I just flash a T-Mobile ROM and T-Mobile baseband and just use it as a gsm device?
I had the same issue
I followed this guide
Spiricore’s Extra Safe Root-To-ROM Guide
search for it and follow it exactly and it will fix your phone.
I had the same exact issue along with my dialer freezing, did this guide and now I am working again. I think when I was flashing I wasn't wiping the phone good enough, this guide tells you to wipe each thing 3 times even though its tedious I did it and it worked when nothing else did.
Nope didn't work. Wiped everything multiple times and reinstall cm nightly, didn't work

The reason why you can't just flash a TMO rom is because they don't have the exact same hardware, there are carrier specific options in the kernel. I repeat, do NOT just flash a TMO rom over your Sprint S4, it will brick. (I've done it to my S3 and it didn't go so well.) If you want the GSM rom, make sure you either flash a Sprint kernel over the TMO rom immediately without rebooting, or (I would recommend) exchange the boot.img files from a Sprint rom over to the TMO rom and remove the device checks. But if anything happens (if you brick) you're on your own.
As for the first question, you can try flashing over a different kernel and make sure it's either aosp or tw depending on your rom. Also wipe data+dalvik+cache. I haven't had that happen to me though...
This phone used to be on the Bluegrass Cellular network, I have contacted them and AT&T with no help. I have rooted the phone using Towel Root and used Advanced Signal Status to change my radio to LTE/GSM auto, and can also now change the radio options within the phone. When I select to register on the AT&T network, it sits for about 3 minutes, and says "Unable to register" the IMEI is clean, I'm assuming I need a custom firmware or something. At this point, I am willing to pay someone to help me fix this, it has caused me so much trouble. Thanks!
Someone had suggested I use This ROM.
Problem is, I need custom recovery, and I can't find one for jfltelra.
TWRP shows all the jflte's but mine (jfltelra)
Phone Info
Galaxy S4 SCH-I545L jfltelra
Android version 4.4.2
Baseband Version: I545LWWUFNK1
Build Number: KOT49H.I545LWWUFNK1
Use twrp for jflteusc works great.
Hey all,
So, a little backstory: I got this HTC 10 from Sprint not too long ago, and little did I know that I would be stuck with Sprint unless I reflash the phone firmware. (after research, asking HTC and Sprint, I received misinformation from reps stating that the phone would work on Verizon with just a carrier unlock issued over the air). Moral of the story: don't rely on customer service :silly:.
Fast forward to now, and I have rooted (temporarily to run Sunshine), S-OFF'd (using Sunshine), changed the CID (for Verizon), and flashed the newest Verizon RUU that developer Dottat kindly posted here.
That worked, full LTE, but then whenever the camera or GPS were accessed by any application, the phone would freeze with a black screen (though it seemed something was still running in the background, as notification sounds would still play, and I could exit by pressing the home button and waiting about a minute). After this, I tried flashing the Viper ROM just for kicks, but then the cellular radios only functioned with 3G coverage (no LTE in a coverage area), and GPS was still broken (the camera issue was fixed with this flash for some reason).
Unfortunately (or maybe not), I am pretty sure /system has been wiped multiple times. I also ran
Code:
htc_fastboot erase modemst1
htc_fastboot erase modemst2
after each install of a new ROM, then performed a factory reset from recovery (just a factory reset, nothing more).
Now I went ahead and used an official ROM from HTC's website in an attempt just to get full functionality working on any carrier. I flashed the USA unlocked variant (and changed the CID to BS_US001. MID is still 2PS650000), but now I am experiencing more missing functionality. The camera and GPS are still missing, and now the SIM card is not detected (when entering the access point names dialog, a message pops up stating that there is no SIM, or SIM error when I am using an activated AT&T SIM). When I enter the test menu (*#*#4636#*#*) and select any option for network mode other than what is default (LTE/CDMA), the new option won't 'stick' (it returns to default after a few seconds).
This sounds to me like there is stale firmware on the device from a previous flash, or that the firmware for these core peripherals is corrupt. Is there a way I can get these devices working again? Or am I now stuck with a bricked device ? I do still have a backup I took of what was installed stock by Sprint (all except for /data...but I don't need that partition, right?)
EDIT: Mods, I am terribly sorry! I meant to post this in HTC 10 Q&A. I don't see a way to delete a thread, so hopefully we can move it.

A MOD should move it soon.
I am not the best here, but hopefully can be of some help.
I would just superCID, save a step for flashing RUU's.
So, when you flash the Verizon RUU, does camera work?
(if you RUU and only have 3g, wipe the modems to get 4g back)
If your trying to use the phone on Verizon I would do the following:
1) Change your CID to Super, 11111111
2) Flash the US Unlocked RUU, http://www.htc.com/us/support/rom-downloads.html#unlocked
3) After it fully boots, reboot into the bootloader & flash the Verizon radio, http://forum.xda-developers.com/verizon-htc-10/how-to/vzw-how-to-unlocked-model-vzw-t3376743
4) Make sure the Preferred Network is set to Global, Settings>Mobile data>Preferred Network
5) Get to the secret menu *#*#4636#*#*, and set the preferred network type to "CDMA/EvDO/GSM/WCDMA/LTE Auto"
I use a Verizon model with the US Unlocked firmware. As far as custom ROMs, some work with Verizon's network and some don't. I'm sure theres a workaround but I've stuck with the US Unlocked firmware, and just use Xposed for any tweaks/mods.
If your trying to use it on AT&T and the radio from the US unlocked RUU should work.

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.

Hi guys!
I'm from Venezuela, I recently acquired a Nexus 6p (h1511), so yes, I'm a noob. When the cell phone arrived in Venezuela, I connected it to the Wi-Fi network without placing a SIM card, and there was an update notification, I executed it, anyway it already came with Oreo 8.1, the update was December, the one that had It was November. After updating the SIM of the operator Movistar, recognizes it since it says "Without service - Movistar", when trying to call it shows the error "Mobile network not available", when trying to do a network search, it gives error, sometimes to one side of the signal bar, appears an R (Roaming I guess) ... I've been doing a lot of research, believe me I would not be creating this post if I was not so desperate, I have many doubts
I took it to a technician, he looked at it and said it was CDMA that there was nothing to do, he wanted to sell me a GSM motherboard, I told him I would think about it, it was strange for me to be just CDMA, I investigate more and I realize that it's dual, and it changes from MEID to IMEI when I put the SIM card ... I did a factory reset and it did not work. I used the options in *#*#4636#*#* the default is LTE/CDMA/UMTS Auto (PRL) ... I tried to put GSM Only or Auto or any option that included GSM. Without apparent results, I think that it did not even change the default option, the radio bands are few, all from the USA (logical being the USA version of the cell phone) ...
Investigating further, I understood that the problem persists in Android Oreo ... Under the official firmware of Google 7.1.2, I follow the steps, I do the unlocking bootloader, flash vendor / radio, flashing system, in the end there is an error , something about user, I really do not remember, something like that could not erase the user partition or had no permissions ... The issue is that I turn on the cell phone, start to do an erasure, then start asking for google account, etc. ... I configure it, but I see everything the same, I enter the configuration and details of the team, it keeps dialing android 8.1.0, but I see that the base band has changed, some apps have changed, like the application of calls ...
Does anyone know what happened? (And no, the SIM problem was not fixed) :crying:
I want to install this ROM
https://forum.xda-developers.com/nexus-6p/development/rom-chroma-11-08-2015-lockscreen-navbar-t3244444
According to many sites and here in XDA comment that it solves the problem, but this is 6.0.1 ... It means that I must flash 6.0 stock? To install the custom? Or can I install on 8.1?
Any other more updated custom rom that solves this problem?
Thank you! :fingers-crossed:
