4.4.2 update creates symlinks to calibration and regulatory files (the actual files are in /system/etc, symlinks are in persist and the symlinks from persist are further linked from another place in /system/etc...) without which the wifi will not work.

[RAZR HD General] kabaldan:
Your WCNSS_qcom_wlan_nv.bin file is way too big. Did you use the one from Atrix HD?

Better use one of the xt925 ones (the correct size is 28456 bytes) that are attached to this post: http://xdaforums.com/showthread.php?t=2701829

But I guess that your main issue are incorrect permissions set for WCNSS_qcom_wlan_nv.bin. You have it set as readable for everyone, which will cause that it will be refused by fw loader.

Use this command to fix it:

su
chmod 660 /persist/WCNSS_qcom_wlan_nv.bin

Missing .bt_nv.bin for xt925

Hi, may you send me the .bt_nv.bin, because mine xt925 doesn't have it?
[RAZR HD General] Graf Schmidt:
Hi,

I don't know exactly where to ask this but since my device got update to 4.4.2 I can't use my motorola headset anymore. It's much like it doesn't get recognized anymore - maybe a bug in programming update?
[RAZR HD General] JoseBerga:
I had the same problem, but with a data format/factory reset I fix that problem..

Enviado desde mi RAZR HD mediante Tapatalk
[RAZR HD General] Graf Schmidt:
Thanks.

I can't remember if I went through factory reset though.

I should try.

P.s.: factory reset through OS or under recovery, by the way?
[RAZR HD General] Graf Schmidt:
Nope, factory reset didn't solve my problem.

It just doesn't recognize microphone on Motorola headset anymore :\.
[RAZR HD General] QAFlight:
I have a XT925, Unlocked, OTA 4.4.2 , 180.46.119.XT925.Retail.en.de. Can this System version be rooted? I am having issues try to flash a custom recovery to gain root. With motofastboot I can reboot, erase cache, etc.. but when I try to flash recovery it does nothing. I am using the factory cable and USB 2.0.

Thanks for any pointers
[RAZR HD General] JoseBerga:
All xt925 with unlocked bootloader can be rooted. Which custom recovery do you tried to flash?

I would've expected for JB radio to NOT work on KK. Why would you try to flash it?
[RAZR HD General] Qix84:
To try , because with the KK radio have poor signal in every place.

Can you upload a flasheable zip with the KK radio please??? or the radio to flash it with fastboot.
[RAZR HD General] capedukewuhaha:

i hope this is allowed here:

i made a small video of the kitkat-update! every lag is because of the screen-recorder-App! :)

[RAZR HD General] Tuckycv:
I haven't really notice poor signal.
[RAZR HD General] Qix84:
Any can upload the radio please ??? I dont want to do a factory reset.
[RAZR HD General] idless:
I am not really sure what the cause was but for a brief while SMS sent/recieve did not work. If xposed is not to blame (and does not seems so), it might be because of something i "froze" with titanium. I froze bug2go and battery tracer, maybe one of those did it. Anyway I did a factory reset and now everything is back to normal.

Does anyone have issues getting into the special 4.4. CWM recovery via the bootmenu? For me it only works maybe 1/3 to ½ of the times I try. I have also seen some wierd white stripes and black screen a couple of times. Maybe the screen drivers are not properly loaded before entering CWM ? In any case this is no fault with the ROM and properly something that gets fixed along the way if more development is done on the recovery.
[RAZR HD General] skeevydude:
Lol....thinking a factory reset will fix that.....

http://sbf.droid-developers.org/phone.php?device=5

the file on the bottom is the KK fastboot, download it, extract it, flash the radio....

unless you're talking about the radio lib under /system, in which case, learn to back up important system crap before messing with them

If it is the lib you'll have to convert the fastboot system.img over to ext4, mount that, then copy whatever you need from there (or search around for one of the uploaded /system dumps....)
[RAZR HD General] Orphee:
I'm not sure the radio from XT926 is the same as XT925...
[RAZR HD General] skeevydude:
It probably isn't, but if someone with a 925 flashed themselves to a 926, well, what choice do they have, other than going back to JB?

EDIT:

Just read pages 1 thru 4....didn't realize ya'll had a 925 OTA...now I feel like a dumbass. Sucks, I still have to wait on AT&T labs and Q3 for the Atrix HD OTA.

Either way, a factory reset won't fix dude's problems....

It has leaked the official Motorola KitKat for xt925, but just updating OTA, and to do it I have to downgrade to 4.1.2 (now i am with CM11)? Is this it?

Excuse me for being dumb!

If i am right, can i do it in my Brazilian xt925?

Tnx in advance!

[RAZR HD General] idless:
In short: the best for most to wait for an official release or at least a full ROM (rather than an OTA update). This leaked OTA only work to one specific 4.1.2 ROM used in France and central Europe. Is fine for the most impatient and willing to risk bricking but if in doubt in any way it is probably best to wait a little (should not be long now).

Question about WiFi

Hello Mr. Orphee, I have a question, I live in Peru and my carrier is Movistar Peru, my system version is currently: 98.50.25002.XT925.Movistar.en.01 for Android 4.1 Jelly Bean, I tried 1 week ago, to instal CM11 using CWM for XT925 (the non touch version of this CWM) I have unlocked boot loader and everything needed to do the process, the thing is, after I flash the ROM, I can't WiFi to work, it activates, and sees the networks but doesn't do anything when I try to connect to my home network, doesn't even say "wrong password" if I try to type in a wrong one, it just does nothing after I type the password, I also tried with Slimkat ROM, having the same results, then one day I had to rush to my girl's house and I was able to connect to her WiFi network, so I couldn't connect to my home's one but I was able to connect to her's, I was wondering if am I going to have this issue after flashing this ROM, or is there a way to solve this problem?, tried chaging router's wifi password, resetting router, changing network ssid, etc, doesn't matter what I do it won't connect to my router, I wiped everything before flashing, including dalvik, and format system, and tried a couple things I found in the forums, like replacing the wlanq files, deleting the wifi folder and so on, tried every method I found on the web but nothing works, thanks a lot for your reply in advance
[RAZR HD General] Tuckycv:
People please READ the instructions. As of now there's only the OTA officially that it Only works if you're in 4.1.2 RTRF. Any other combo is a no go until further notice.

Try updating your router's firmware it that's possible. Sadly, over the years I've seen plenty of people flash custom roms and lose WiFi at their home and have it work at other places because they have an incompatible router. Some take this as a sign to update that 10 year old WiFi router.

It should work with stock Moto KitKat, should...

[RAZR HD General] MauricioBR:
I kinda wished that they moved a bit further on the almost-stock experience with KK on the Razr line.

Their launcher is not exactly my favorite -- I don't really like the text on the fixed icons and the quick menu is now useless, but I guess we can just install the Google Now Launcher or another one to address that. :)
[RAZR HD General] six37:
Just installed Google Now Launcher. It is as snappy as the default motorola launcher. Those quick settings are useless indeed. Most annoying thing are those black bezels in the bottom and top. On 4.1.2 the wallpaper was full screen and under the onscreen buttons not like this!!!
[RAZR HD General] Lipeao:
So, those steps to flash the stock kitkat will only work if we have the 4.1.2 retail france right? Anyone has the file to download it and "flash" thru RSD?
[RAZR HD General] CoinCoin88:
Please, please.... read the threads here.

It's really a shame that a handful people provide valuable information only to have them overlooked.

All credits to Orphee for recent xt925 soak-test OTA. There is NO other way to upgrade xt925 to 4.4 other than this OTA. If "flash from zip" seems too weird for you, then you should not even think about trying, and wait patiently for a full XML RSD-compliant upgrade.

People, please READ the thread as many questions have been answered numerous times before.

edit: btw, my understanding is that this is a soak-test release. That means possibly buggy (although reports so far tend to say otherwise aside from very specific issues. Again, read the thread, 4-5 pages isn't that much) and this is not a final release.

---------- Post added at 04:42 PM ---------- Previous post was at 04:34 PM ----------

Now, on a more positive note.

I was so fed up with my laggy 4.1.2 that I decided to try this OTA (considering I was gonna reflash anyway, why not go to 4.4...).

Followed Orphee's guide, everything is OK (the last CWM recovery has been updated to 6.0.4.9 since then but if you've reached this step it's likely you won't have any pb with that).

As I'm unlocked it's way easier to re-acquire root, however for some reason Chainfire's SuperSU would not show any notifications and TB (firt thing I needed to have root) kept saying "couldn't acquire root".

Here is what actually worked:

1) Sideloaded Chainfire's SuperSU from recovery (http://download.chainfire.eu/447/SuperSU/), su binary was correctly installed (adb shell; su -> gave me a su prompt). Installed apps couldn't acquire SU rights for some reason.

2) In SuperSU, used "change SU manager"

3) Rebooted

4) Installed Superuser from ChainDD

5) SU notifications were now displayed and apps granted su privilege.

I'm still wondering why this did not work first hand with SuperSU, but I don't really care which SU manager I'm using, as long as it grants permission when it should. Hope this helps!
[RAZR HD General] Lipeao:
It isn't weird for me, I just want to know where I could find the stock firmware from Europe o France to upgrade it
[RAZR HD General] CoinCoin88:
OK, my bad, and my apologies, I misinterpreted your question (hopefully my large-bold intervention will still prevent the -other- question to be asked). I thought you were asking for a RSD-compliant version of 4.4

I might have a bit overreacted, but it's really frustrating to see someone's work overlooked by so many here. This was not your case and again I apologize for that!

4.1.2 firmware is available on droid-developers: http://sbf.droid-developers.org/phone.php?device=6 "Retail Central Europe"
[RAZR HD General] Lipeao:
I'm having problems flashing the stock firmware, I can't flash it, it gives an error about security downgraded and on RSD fails on 2/22 step, should I flash a custom ROM before flash the stock firmware? Because i'm on Stock firmware from Brazil
[RAZR HD General] Tuckycv:
As far as I know, once you upgrade to KK there's no going back Although I do believe i have read some people have been able to go back.
[RAZR HD General] Lipeao:
But I haven't flashed KitKat yet, i'm still having problems with the RSD
[RAZR HD General] kumeipark:
From xlm remove the "get var" and "patition" line and try
[RAZR HD General] Tuckycv:
Oh I had some issues like that too, if you having boot stuck on that error, try getting into fastboot mode, volume up +volume down + power and the on you computer using fastboot type fastboot oem mode_fb_clean and it should get you out of it. Then remember to delete the line get var as stated up.
[RAZR HD General] Lipeao:
Well... I could get the kitkat, but Wifi isn't working, it shows the network but when I try to connect it says "connecting" and doensn't connect
[RAZR HD General] kumeipark:
For those who want to cross flash their XT925 to Central Europe Retail 4.1.2 must remove the following lines from RSD XML.

<step operation="getvar" var="max-download-size" />
<step operation="flash" partition="partition" filename="partition_signed" MD5="80ed27f9dbe459defefb819e92f1ea33" />
[RAZR HD General] Orphee:
If you need/want to go back to RTFR 4.1.2 from my modified OTA file/ROM, you must remove "partition_signed" and "tz_signed" lines from XML file.

[RAZR HD General] Orphee:
Your alternative is to wait the official OTA release sent to your phone in few days/weeks/months.

---------- Post added at 05:29 PM ---------- Previous post was at 05:19 PM ----------

You should add a note to mention it it's the soak test release, not the final OTA
[RAZR HD General] m_torresagasti:
You are right Orphee, its done! thanks!
[RAZR HD General] CoinCoin88:
Possible bugs I encountered with this soak test OTA so far:

- if you're using a third-party SMS/MMS app (and I mean any other than the Moto one, this includes Hangouts) you can't freeze the official SMS app with TB. When doing so, other messaging apps will crash and fc as soon as you try to input a new message.. Unfreezeing the moto SMS app solves the problem.

- Today I had my first unexpected crash which was not a force close while on hangouts. Suddenly the screen fade to black line by line, "matrix" style. 5-6s of black screen, then I got back to my dekstops and could go again in Hangouts.

Other than that, it feels really smooth, but again we'll see in a couple months about that.
[RAZR HD General] CoinCoin88:
Give time to your system to rot a little bit with the load of crap you can install, uninstall, download, erase, receive/send...
[RAZR HD General] etenmark:
Agreed, it's probably best to wait anyway since you take less of a risk and if the XT925 release is anything like the XT926 then the official OTA should start rolling out to everybody very very soon. I think with the XT926 is followed about a week or two later.. or was it a few days? Anyway it was quick.
[RAZR HD General] CoinCoin88:
I've been following the xt926 rollout (actually i was secretely hoping both xt925 and xt926 would be released at the same time... how fool of me :)) and iirc the official OTA was released a couple days after the soak-test OTA was leaked... so it's likely the soak test is just a mere "sample release" before opening the valve.
[RAZR HD General] Orphee:
Hello,

I had the SMS receive bug too with soak test, I'm back to CM11. I can't miss SMSs so I don't want to take the risk to have the same bug again.
[RAZR HD General] CoinCoin88:
Had it too, really weird stuff. It didn't happen at first, I received several sms/mms before it appeared. One second I could'n send or receive anything. Oddly enough, this was ~ the same time I installed an apk I found couple months ago (SMS multi part cleaner; because my carrier is sometimes buggy and duplicates parts of multi-sms messages which enventually end up mixed up in others, more details here: https://code.google.com/p/android/issues/detail?id=28697). Uninstalling it did not help recover my receiving/sending functionnality, I had to reset to factory. Been 3 days, so far so good.
[RAZR HD General] idless:
Same sms bug also seen here and remedied by resetting. First thought it was exposed interfering somehow. I hope they (motorola) get this bug fixed before final release. In any case I will probably soon return to a custom ROM (hopefully utilizing new libraries). I really miss some of the UI enhancements found in various ROMs.
[RAZR HD General] hugodefcon:
did you get it working?
[RAZR HD General] RockyRock:
I got the SMS Bug too. :(

Can anyone upload the old sms and sms-center app?

I would try flashing them and see what happens...
[RAZR HD General] hugodefcon:
Any update on when the official might arrive?
[RAZR HD General] Kenny_31:
The soak test is not ended yet, on last friday Motorola pushed an incremental update fixing some known bugs.
[RAZR HD General] CoinCoin88:
Did they comment on what bug were addressed ? Or maybe it's under NDA...

I experience regular drop of data connection (once a day or two maybe ?), and turning it off and on again won't do any good. I have to reboot the phone to get it running again.
[RAZR HD General] RockyRock:
Could anyone upload the update please?
[RAZR HD General] aamd11:
Not to get too off topic here, but has anyone with the Rogers/Fido (Canada) XT925 heard any news of the KK update? I have yet to hear anything, other than the fact that Motorola's update page says we're getting it

[RAZR HD General] MickyMax:
Hey guys, what's new about the soak test please?

Thanks
[RAZR HD General] Orphee:
It seems there is a incremental soak test update but not leaked yet.

No more information on it.
[RAZR HD General] CoinCoin88:
IIRC @DavidSchuster said they were securing carrier lab testing and not expect final release before late Q3. I assume the retail version might be a little early, since it's already in soak test (with at least one incremental update).
[RAZR HD General] Orphee:
Hi,

I removed my link to the OTA modified ZIP...

There is wrong informations published somewere telling my modified OTA is the official OTA release...

I can't leave people think it is...

We know now this leaked OTA release is buggy (SMS) so I don't want users to believe they are flashing the official OTA.

Sorry...
[RAZR HD General] john duff:
I installed it a few days ago and haven't seen many drawbacks.

If you

-perform a factory reset after upgrade,

-be careful to set SMS/MMS app as the defaut application for messages AFTER RESTORING WITH SMS BACKUP & RESTORE who calls for this privilege (This is a kitkat requirement)

then, SMS are correctly received. I haven't missed one.

Among the drawbacks, I have had one or two crashes that triggered a crash report upload somewhere to Motorola's or NSA, and that's all.

If you disable the built-in battery monitor, you end up with a little better battery life (I measured it using the same set of apps, and call & internet usage)

I originally thought it was the official kitkat update. But it's allright since battery life seems better.
[RAZR HD General] CoinCoin88:
Where has this been posted? The OP is pretty clear, I wouldn't say you should care about some idiots downloading and flashing things without knowing what they flash... :/

---------- Post added at 06:10 PM ---------- Previous post was at 06:07 PM ----------

Yup, but womewhere along the road SMS decided to not work at all after doing all this (well, actually didn't do a factory reset after upgrading, but flashing RTFR did so...). One minute they were working, the other I couldn't send or receive anything. Freezing apps, rebooting.... nothing to do except a factory reset. So it's not that good.

Hopefully doing a factory reset after upgrading to KK solves it definitely, but there's really no way to know.
[RAZR HD General] john duff:
What makes me think that this upgrade doesn't bring the phone to the 'factory' state, is that I didn't have the full setup wizard when I turned it on (google accounts, wifi and so...). I had to set up my google account manually. After the reset, the wizard was back with all his powers:)

Anyway, did anybody have SMS problems after performing a factory reset ? Please raise your hand :) I would like to be sure that there are no risks of missed messages after factory reset.
