Flashed nmf26v now no cellular data, help! - Google Pixel Questions & Answers

Hello, I'm in a tough spot and would appreciate any help I can get.
My pixel came from Google but I use it on Verizon's network.
I had twrp/supersu installed and then flashed over it nmf26v using the flash-all.bat (deleting the -w flag) and now my phone has no cellular data connection. It can make/receive calls+texts and wifi data works, but I get the little 'x' over the bars and no cellular data.
I've tried flashing the new radio file nmf26o_radio-sailfish-8996-012511-1611190200.img but that didn't help.
Has anyone else seen this before?
Many thanks in advance.
---Paul

Check in settings->data usage-> cellular data. Make sure it's turned on. Happened once to me but not sure how.

Thanks, I tried that, but no joy. I've finally "fixed" it by putting the "-w" back in the flash-all.bat (wiping my phone) and using the the nmf26u image.
I'm still not sure what happened (and am not psyched about restoring everything to "the way I like it"), but at least I've got the modem working again.

NMF26V is for international devices (it's listed as (NMF26V, Jan 2017, Europe/O2))
NMF26U would be the image you wanted from the start.

I flashed the v update on a Verizon pixel and have had no issues thus far. Calls texts data all working fine.

The V image does work fine even on Verizon, it's what most of the ROMs are based off of as well. OP, what did you have installed before flashing that image file? If it was a custom ROM, that's why you're having problems.

I was running stock NDE63V plus TWRP 3.0-alpha2 and SuperSU. Before doing the flash I upgraded TWRP to RC-1 and I think things went wrong from that.
The full-factory wipe+flash-all solved it, but it was painful.
---Paul

That happens to me before.. it was because the flash-all.bat dint flash the NMF26V Vendor Image, so i flashed it manually (extracted from the zip) and data works again, with custom and stock ROM.. my pixel on the beginning was U version and vendor...

Trying to recover from softbrick

Ok, so here's what happened.
Been running on this Pho Q for a week or two stock, then last night ran MotoChopper to root. Made a Titanium Backup, then unlocked the bootloader. Flashed TWRP via fastboot successfully, then flashed the 10/16 nightly of CM10.2, and Gapps. It booted no problem and I started setting up the phone. Got a weird lockup of playstore (unresponsive install button, and back just exited), so I rebooted.
Here the phone got stuck (left it for at least 10 minutes) at the boot image (unlocked bootloader).
I could hold vol up + power and reboot into TWRP, but subsequent flashes of CM10.2 w/ or w/o Gapps resulted in the same.
So, I have an OpenRecovery nandroid image of the stock system from another phone (with a bad ESN - got burned on ebay, but now using it as a test phone), so I copied that over and restored it. It booted and rebooted fine. Flashed CM10.2, it booted/rebooted fine.
But now, trying to make calls I get a recording saying "Your account is not authorized to call this number". Including trying to call voicemail. I also notice a high-pitched noise/hum over the speaker when the call is connected. Data/LTE is working fine.
Could I have screwed up a radio image or something? Would something about the account connected to the bad ESN phone have come over in the restore, and persist through the CM flash? Any thoughts would be most helpful.
Why didn't you restore to stock with RSD Lite?
I would recommend that. However, flashing a 'bad' phone shouldn't copy the ESN over - there's a lot of hacking (some of it illegal) in order to do a true ESN swap.

Restoring with RSD Lite 6.0 works (after removing the getvar lines from the xml) - I can get back to stock and it goes through Handsfree activation and is good as stock.
So I just tried again.. flash TWRP, flash CM10.2 and Gapps, it works. Test calling. It works. Reboot. Hang. WTF...?

Apparently this was all a problem with the late builds of CM10.2 (4.3.1). The latest stable 10.1 is working much better. Thanks for the advice!

[Q] Problems flashing an already rooted 4.4.3 over 4.4.2

I flashed the ROM and baseband per instructions in this thread: http://forum.xda-developers.com/goo...-android-4-4-3-ktu84m-rooted-busybox-t2557523
I had 4.4.2 and he said it had to be stock, and it was with the exception of potentially having some system files modified due to other apps, like Android Tuner. I wiped Dalvik cache and regular cache, installed both files as mentioned through TWRP, and yet upon starting I get a notice to update to 4.4.3 despite already being on 4.4.3, and it can't connect to T-Mobile which is my service provider. Am I doing something wrong here? I figured by "stock" ROM he meant the original and not CyanogenMod or anything like it. Was that supposed to mean stock Android with zero modifications to the system files?
I didn't want to do a factory reset and have to redo all my data and applications, but if I must then I will.
There is a rough thunderstorm going on so maybe that knocked out T-Mobile service, but I find it rather coincidental.
]UPDATE] Turns out that the storm coincidentally disabled the towers at around the exact time I updated my phone. The phone was flashed fine. T-Mobile is the problem. Thanks for the help!
It doesn't matter what ROM you're coming from but if it's not stock you need to wipe. But whatever mods you have on stock is irrelevant.
If you're having issues connecting,, wiping cache is often the cause. Check. Our imei etc is correct. Maybe fastboot flash a stock cache image or Nandroid restore

It was the original stock that shipped with the phone, with potentially some files modified from an application. Strangely when searching for networks to connect to, Sprint and AT&T show up as normal but not T-Mobile, although their APN's show up as if I am connected but can't get access to their service.
The IMEI within the phone appears to match the worn off label. Either way, I cleared the Dalvik and regular cache again so I'll see what happens when the phone finishes booting.
Surely it's booted by now?

It finished updating the apps and didn't get a connection, however when I traveled outside of my home zone to work, after I reach the spot outside of the city at which there is no LTE support and it drops to EDGE the connection picked up and remained. After I returned from work and got back in the city near my home where it switches back to LTE the connection dropped again and remained that way even after wiping the caches again.
Does this still sound like a software problem or maybe it's on T-Mobile's end?
Fixed

3G data working, LTE/Spark not working

Rooted stock ROM phone. To make a long story short I made a bad flash with an incompatible file. Restoring a backup resolved everything with one exception: 4G. Data works fine through 3G or wifi. No 4G data for apps. Curiously opening settings > Activate This Device pops spark right up if it's enabled in settings > More Networks > Mobile Networks > Network Mode but that's the only time. Also noted are APNs only list 3 "Wholesales" options which are all mostly empty.
The apns-config.xml file is present in /system/etc. All the appropriate data appears to be contained within it. Wiping does not restore the APN settings. Factory reset does not work either. Reflashing the stock rooted ROM does not resolve it. What else can I do?
Are you getting a 'Insert SIM Card' message is anything.
I have this issue with my S5. I usually run through a reactivation to fix mine.
No, though reactivation is a good suggestion. Thanks!
Upon further observation the Update PRL application says it's initializing but nothing happens. What is going on here?
You said you tried stock rooted? Is that the full factory tar flashed with odin?

I would try that first. It would rule out trying to flash something that isn't overwriting certain partition items like the modem.
Keep in mind that the internal SD might get wiped when flashing the full factory tar in odin and also that the you NEED to enter download mode from a powered off state to properly flash the full tar.
There are threads here in android development for the full tar files or you can also find them on sammobile's website as well.
If flashing the latest OA6 doesn't work, you may want to try going back to one of the older builds, 4.4.4 or 4.4.2 build too.

This was the chosen route. Flashed back to NE5, rooted again, flashed the same rooted OA6 ROM. Now there's a sweet little spark at the top of the screen. I was hoping to avoid all that but hey, that's what I get for a dumb mistake.
Thanks to everyone who replied! :good:

Issues after cm13 flashing, infamous bootloop, and other festivities

Hi everyone.
Let's start from the beginning, and by advance excuse me for my poor English : I happen to be a delighted owner of the Oneplus One by the Oneplus company. I've flashed different versions of cyanogen on my phone, rooted it multiple times and I never encountered any kind of problems. Thus, until I decide yesterday to flash the latest release of cyanogen, cm13 (nightly). I did some researches, followed the usual steps, flashed the right opengapps version along with cm13 and.. everything went great. Except that my phone couldn't resolve himself to detect my SIM card anymore. I tried different things in order to solve the problem, including re-wipe the phone "factory reset" style, removing SIM card, wait for the phone to cool down and played with data roaming, but nothing worked. Fortunately I had my fresh nandroid backup waiting to be restored. That's when the real deal start :
even after having restored the full nandroid backup (which make me downgrade to cm12.1), the SIM card wasn't detected.
So I decided to wipe data, dalvik, cache and system, in order to get my phone back to its original state. But the problem remains, and worst of all, the phone now tends to reboot punctually without any reasons.
I surely did something wrong for the phone to end in this state, but I can't see what..
I use TWRP 2.8.7.0 custom recovery, and the phone OS is now cm12.1-YOG4PAS3JL.
Oneplus One 64GB.
Sorry for the length of the complaint, and by advance thanks for your answers.
P.S : I did tried to search for similar threads in the forum, but I didn't manage to found anything that was directly related.
It could be an issue with the modem not being flashed properly when you went from Lollipop to Marshmallow due to TWRP 2.8.7.0. Try TWRP 2.8.6.0, and then either restore the nandroid backup or clean wipe + reflash CM13 nightly.

Thanks a lot for your response. I've been searching a lot and the problem effectively seems to be the modem not being flashed properly. So I tried to flash it manually, (found the file 2 threads higher, sorry I can't post links yet) via fastboot and then flashing cm13 (with twrp 2.8.6.0), considering the fact it seems to have worked for others.
But no matter what I do, the issue remains : the phone isn't able to detect SIM card and goes into crash, rebooting every 2mn..
I've tried to flash cm13 unnoficial version by sultan, following his instructions, but no improvement either.
Even my nandroid backup (running cm 12.1) can't detect SIM anymore, have serious wifi connectivity issues, and keeps rebooting randomly at very reguliar intervals..
I'm really beggining to feel hopeless,
but thanks again for your time and your advices, really apreciate it.
It seems that I have same problem..... after flashing CM13 and restoring backup
Any progress with this problem?
Edit - If my phone is connected into PC with USB cable it doesnt restarts

Same for me, the phone stops crashing and rebooting randomly once connected to pc via USB cable. But still doesn't recognize SIM card. Wifi also seems to work better.
No further progress unfortunately, I've tried everything, from restoring the phone to its factory state to flashing all "stable" roms (cyanogen), nothing worked.

Already saw it, but thanks ^^ that's where i found my file modemst.bin
so did it work for you ?
The same thing happened to me last week. I was using Materialized TWRP 2.8.7.0, which I think caused issues with my updating of Sultanxda's 13.1 ROM. SIM card was never detected, phone would restart shortly after every boot. I tried everything I could find to get my baseband and IMEI back.
In the end, only this solution worked for me, and I had to do it twice. I don't know why.
I had the same problem. I got back to TWRP 2.8.6.0 and then flashed the latest CM13(wiped System). after that without wipe i flashed sultans's CM13 then gapps and got the sim working again.

I've tried multiple times, it doesn't work. SIM card is not recognized, phones goes to reboot after 30s of use.
Whatever rom I flash the problem ain't solved, even after factory reset from original OS (cm 12.1)..
I really begin to think there is no solution, I've tried to flash my phone at least 20 times with different roms, fix, firmwares, modem, everything that is available on the net and I couldn't notice even the slightest change in the comportment of my phone.
Anyway, thanks a lot for your proposal, I guess it HAVE to work, but for some irrational reason it doesn't...

Did U flash over TWRP or ADB?
Just popping in to say I have the same problem. I'm trying the various solutions presented in the thread and I'll come back and report if anything worked. I would also appreciate any other suggestions that you may have
For the record, I got into this predicament through the following steps:
1. I was flashing some CM nightly (sorry, I don't remember which one), and after reboot the touch screen didn't work anymore
2. I flashed the OxygenOs .zip that I had saved on internal storage through TWRP
3. After flash touch screen worked but no sim detected
4. Flashed CM 12.1 still no sim
5. Flashed back to OxyOs, still no sim. Curiously I am unable to reboot via software.
Anyway, I basically have all weekend to work on this, so awayyyy we go!

<Edit>
Wow that was fast. I followed this guy's instructions (fastboot flashing modemst, then CM12.1) and it seems to be working like a charm! Good luck everybody else!

I flashed via TWRP(2.6.8.0) and via ADB for modemst1.bin and modemst2.bin.
By the way, there's a little improvement : I flashed kalkulin's_stock_OPO Rom and that stopped my phone from rebooting.
Now cm13 is running kinda fine, except it still doesn't detect SIM card, even after reflashing modemst1 and modemst2
Edit : When I try to flash oxygenos, oneplus fix or cm12.1, (roms that are supposed to fix sim detection problem), it doesn't work : Error flashing Zip file. via adb or twrp, that's the same. (excepting the fact that error in adb is about trustzone)
I think my efs partition is somehow corrupt, and unfortunately i have no way to restore it.

It's not supposed to be flashed. Unzip the archive on a Windows PC, then use the .bat files in there to fix your phone.

Effectively, I kinda did things completely wrong there, sorry. (I'm an exclusive linux user for my defense ^^)
Okay guys, I finally solved my problems.
Here's what I did to fix reboot crashes and SIM detection issues :
-Flash TWRP(2.8.6.0)
-Wipe everything except internal storage
-Flash Calkulin's_Stock_OPO_XNPH44S_ROM_v1.0.zip (can't post links yet, sorry)
-Boot system
-Once done, reboot to bootloader (in command prompt : sudo adb reboot bootloader)
-In command prompt, type the following commands (It will delete modem and /persist partition ! be careful) :
fastboot erase modemst1
fastboot erase modemst2
fastboot erase persist
-If you need to fix "Unable to mount /persist" error in TWRP :
adb shell
make_ext4fs /dev/block/mmcblk0p15
-Flash Oxygen OS (i flashed oxygen_1.0.0_flashable.zip)
That should restore EFS and fix the issues.
Well, that was kind off a pain in the ass, but now my problem is solved, and i'm currently running cm13 quite fine.
Make a backup of your EFS partition.
Thanks to all the people that helped me by posting in this thread !
It's a nightly build, it bound to have some problems.

No mobile data after flash. Nothing will bring it back

>> Partial solution was found; still looking for the root of the problem. <<
I recently decided to take the plunge and root my OnePlus One and install sultanXDA's CM 13 ROM on it. It was all going well until I booted up into the ROM and discovered that I couldn't get any mobile data. Everything else was working, calling, texting, wifi, but mobile data seemed to refuse to work. Since I initially flashed sultan's ROM with TWRP 3.0.0, I suspected it was a problem with my modem. Though unable to install TWRP 2.8.6.0 to re-flash everything, I did still flash a new modem via ADB. This didn't help.
I have tried many things to fix this. I rebooted/reflashed. I flashed different ROMs. I tried flashing on TWRP 2.8.6.1, though I believe that one has the same modem problem as the versions after it. As mentioned above I tried flashing a modem over ADB. I took out and re inserted my SIM card. In the end, I tried this guide here to restore my phone to it's original state. The guide flashes the stock versions of everything via ADB. Though it did return me to unrooted COS 12.1, it was not able to resolve my data problem.
After the total reset, all I can think that could be causing it is a hardware problem or that it is caused by something not reset in the 100% restore above.
If any of y'all can help my solve this, or at least offer insight, I would be very grateful.
Preemptive Edit I Guess: This thread was just suggested to me while writing this. I'm going to try the solution here and report back. It's OnePlus' reset to stock method. I'm not expecting much after my first 100% reset attempt, but we'll see.
EDIT: Ok, so the solution above fixed my problem... (edit again: turned out to only be a partial solution. See below.)
I would feel really dumb right now if it weren't for the fact that I slaved over this problem for a good ~8 hours before writing this post. Anyways, I'm not sure how to delete this post or mark it as solved. Sorry for the trouble y'all.
Never delete this post !!
I have the same problem, and I spent much more time to find a solution.
I will try this and will update.
Is it a clean stock rom?
Edit:
Didn't help for me ..
Still the same problem, No mobile internet connection.
Thx anyway.
Yeah, actually I was too hasty is identifying this as the solution. For me, the stock reset brought me back to CM 11 which didn't have a problem with mobile data. But if I try to flash a later ROM or update via OTA, the problem returns. I'm still trying to figure out what is causing it. The only information I can find points to it being a modem problem or APN problem, but I'm sure I have sufficiently checked both of those already.
Either way, I'll keep looking. If I find something I'll return here with it. Good luck

I gave this a try, but booting up after step 3 I still had the same problem. If I understand this method correctly, I think it is essentially the same as the other full restore methods I tried.
I think I may have found the problem though. I was looking at OnePlus' guide to installing OxygenOS. In it they said, "do not try to flash this build through TWRP. You will most likely lose your radio and IMEI which means a trip to our customer support." At this point I have repeatedly reset/restored my modem/radio so I don't think that is the problem, but I haven't seen anything about IMEI before. The IMEI is apparently stored in the EFS partition which as far as I can tell, is not touched by any of the restore methods I have tried. I took a look at my IMEI (about phone -> status) and it turns out my IMEI SV is 00. It's supposed to be a 16 digit number. I found a guide to fixing it, but I think I will just contact OnePlus customer support first.
I'll be back later with my results.

At this point I have repeatedly reset/restored my modem/radio so I don't think that is the problem, but I haven't seen anything about IMEI before. The IMEI is apparently stored in the EFS partition which as far as I can tell, is not touched by any of the restore methods I have tried. I took a look at my IMEI (about phone -> status) and it turns out my IMEI SV is 00. It's supposed to be a 16 digit number. I found a guide to fixing it, but I think I will just contact OnePlus customer support first.
I'll be back later with my results.

Are you flashing each of the extracted .img files from fastboot, exactly like the guide shows, or are you doing something else?

Yep, I ran each command listed in the guide and my phone was definitely in fastboot. Each command had a collections of "OKAY"s and ended with a "finished", which I assume means it executed as expected.
I have tried 2 different sim cards in my OPO (of two different companies, one of them as mine), and mobile data worked perfectly. Is it possible that my phone is ok and the problem happened in the sim card?
AND... my IMEI SV is 00 too. please update here if it has a connection.
Thank you !

I'm not entirely sure what you're saying. Did it not work with the first SIM card, but it worked with the second?
Mobile data problem was occured (to me), after I rooted my OPO and tried to flash a new rom.
I still can't understand how it convinced my sim card, but the fact is that I tried two (to be sure) other sim cards which are not mine, and mobile data worked well.
When I returned my original sim card, problem started again.
So I am almost sure that sim card has a connection, but can't understand why. And why it happend precisely now, cause it worked well over two years.

Why don't you flash twrp flashable modem?
If your network is present but no data , mostly data service problem. Are you pay your mobile bills ?
Are you activate data services ?

...yes i paid my bills ..
- my network connection to provider is dead...it worked perfecly for 1 month out of the box (see original posting for detailed action i took) this thread is about lack of data connection...but also MODEM related???
- tried the brand new simcard in my old Samsung sII... works perfetly, network connection with provider, data connection and calling..so no simcard problem
Long shot. Change any APN settings from IPv6 to IPv4. That was my problem when I had text/voice but no data.
I made a post on this and then called att gophone, due to seeing other sims working on this thread, and he helped me to fix. Posting my fix here in case others with isue find this post instead of mine.
Turned off wifi.
Turned off cellular data.
Went to APN and changed the apn (ATT Go Phone) from pta to nxtgenphone.
Turned on cellular data.
Finally had H+ above he signal bar, but had an X inside the bar.
Don't know if he did anything on his end, but the X went away after a couple of minutes.
Data was working, albeit kinda slow.
Turned off phone for three minutes per ATT rep.
Rebooted.
Data still slow, but it is at least working. Thinking I need to flash different modem. Battery usage has been higher the last day or two since I flashed c7 anyways.
