0.15 is newer than 0.17?

Am I missing some new version naming convention?

I get that the OP dates show that 0.15 is a newer date but it doesn't make sense in terms of version release...

Perhaps it was the date that Qualcomm released it to the public, but I'd bet that it's actually older than 0.17

Hey pretty new to the nexus, can I flash the Backup efs zip using cwm?
[Nexus 5 Android Development] cral:
I wonder if switching the modem to .15 will help with T-mobile. Sometimes calls go straight to voicemail, phone won't even ring. I've tested it complete stock, with root or without , with and without custom recovery and kernel. The last thing for me to change would be the modem. I've called t-mobile and they have supposedly done everything they can on their side but I'm still having issues.

flashed yesterday the .15 modem from D820 on my D821 ... an i've got a much better signal and now also the switch between 3G and 2G is working fast and without data drops as before!!!

what the newest radio/modem? im on M8974A-1.0.25.0.17... Is that the newest??
[Nexus 5 Android Development] jcsww:
Depends what you go by. If by release date, the .15 is newer. If by version numbers, the .17 is newer.
[Nexus 5 Android Development] jd1639:
I've heard the md5's are the same for both files. Which means they are the exact same file.
[Nexus 5 Android Development] Nbsss:
I mean the 0.15 modem?
[Nexus 5 Android Development] autoprime:
both the D821 and D820 use the same modems. They are interchangeable. Currently I'm able to get more modems for D820.. but I'd assume the same modem pulled from D821 would have matching md5(which is confirmed on both the D820/D821 shipping modems).
[Nexus 5 Android Development] Nbsss:
Thanks mate, I'll try flashing it then.
[Nexus 5 Android Development] destynova1988:
I can confirm that flashing D821 on D820 does not harm the phone. Just did it. Actually got a better 3G signal as I live in Brazil and I should be using the international version not the D820 which I got.

I only hoped to get 4g working, but had no success in this attempt. Here we use band 7 2600.

Fun fact is that D820, supports 2600 frequency, but only TDD and not FDD which is used here.

Hope we can find some workaround for this.
[Nexus 5 Android Development] jcsww:
I am kind of hoping the two radios can be combined into one as well. Turning this phone into the best travelers solution available really would be amazing! The radios as they are already are pretty awesome for coverage but having them both in one would be as close to perfect as we will probably ever get.
[Nexus 5 Android Development] IIMaxII:
Well I get a better signal even in some places where I didn't get signal on 0.17 so it has to be an improvement or just bad coding in 0.17

---------- Post added at 05:26 AM ---------- Previous post was at 05:25 AM ----------

They're essentially the same radio dude. :P
[Nexus 5 Android Development] jcsww:
Perhaps but I want all of the bands supported in one. Is there a way find out which bands the phone is accessing for LTE to see if my stock D820 radio is also picking up the bands in the D821 that the D820 doesn't list as supported?
[Nexus 5 Android Development] mark1s:
I really have a strange bug and I can't tell anymore if it is software related or hardware related.

Long story short : I live in Canada and I am on Rogers Network. About wo days ago, I tried to flash the D281 antenna. Since then, it looks like if my radio on my N5 have really really poor 3G . It's to the point that my phone only wants to stay on Edge / GPRS network and will only connect to H+ sometime. I never had any problem connecting to H+ at home before (still living in a non-lte area).

I tried many time to do a factory reset to my Nexus 5 and tried every radio offered on this thead but still have the issue.

Today I tried 2 different carriers sim card on my phone and they both had 3G without any problem. After few hours of debugging, Fido just told me politely to **** off since I haven't bought my phone directly from them but from Google. Really odds since my phone seems to runs fine on ther carriers.

I'm just wondering if flashing a radio could end up in possible hardware damage? :(

I will possibly switch to another carrier after the last answer that Fido gave me but I still hope that at least my phone is not permanently broken.
[Nexus 5 Android Development] jcsww:
Rogers sucks! I spend part of the year in South East Toronto where I barely can hold a bar of LTE. Even H+ and 3G sometimes completely drop to Edge for me. I found flashing to the D820 .15 radio was an improvement for staying on H+ more consistently. Two things I always do when flashing a radio is, I wipe cache and dalvik, flash the radio, reboot once, and then reboot a couple of more times. This seems to lt the radio settle in. With no LTE coverage in your area, go to the dialer and type in, *#*#4636#*#*, tap Phone Information, and set the Preferred Network Type to WCDMA Preferred. This will help keep you on H+ for Rogers.
[Nexus 5 Android Development] Vlad_M:
Is it possible to enable EU LTE bands by flashing the D821 modem to a D820 N5, or is this a hardware difference?
[Nexus 5 Android Development] jcsww:
I believe (correct me if I am wrong) but the radio in the D820 and D821 are the same. The radeio software for each determines which bands it is looking for. From my understanding, there is nothing available yet to allow all bands from both radios to work as one piece of awesomeness.
[Nexus 5 Android Development] mark1s:
Google accepted to change my phone. Earlier today, I were about 100 metres away from the cellular tower and the phone still had a pretty bad connection.

My sim card is working perfectly fine on my old Nexus 4 and on a Galaxy S4, making the problem attributable to the Nexus 5 only, it's really odd. What a bad adventure. :crying:

[Nexus 5 Android Development] jcsww:
Good luck with the new one! I can get pretty close to the cell twoer for Rogers at Elesmere between Scarborough Gold Club and Orton Park and still get crap signal. That tower though has been pretty much broken for years and reporting it doesn't do any good. When it rains, that tower practically shuts down but they are too cheap to fix it. Before you send your phone back, try something for me if you have a chance. I usually test Rogers against Telus. With crap signal in that Scarborough area, I get 3 more bars of signal on Telus in comparison.
[Nexus 5 Android Development] treIII:
Where would I get this hybrid radio that you speak of? And I'd it OK to use with our nexus 5? Thanks
[Nexus 5 Android Development] drawde40599:
Your getting better signal with KRT01B?
[Nexus 5 Android Development] RussianBear:
Only for n4.
[Nexus 5 Android Development] mark1s:
I already tried my Nexus 5 on Telus with the sim card of my brother and I did indeed had a better coverage at home. The phone stayed on 3G without any issue but didn't had 4/4 signal bars of signal at home like on his Sony xperia S.

The main reason why I'm staying with Fido is because I currently have a good plan with 6 gigs of data for less than 60$ montly. But Vidéotron is currently offering something similar for the same price (without Canada-Wide roaming of course) and my Nexus 5 had no problem at all connecting to their antenna with 4/4 signal bars. In fact the only network that my Nexus 5 sees in the basement right now is the Vidéotron's network.

The strangest part is really that my phone was running perfectly fine with Rogers network about 3 days ago only.
[Nexus 5 Android Development] treIII:
I backed up efs immediately. Followed op instructions to a t. I read a lot before I touch a phone or any device. I have 2.5 years experience with routing etc. But I have a problem. I live in US. So I used 820 files, zips. But after flashing some of the older radios my phone wants to stay on edge now where I always had a good hspa connection. I've tried all that I know. Which may be more or less than others. I'm no dev. Also I've noticed after flashing back to the radio my phone came with that I am not getting the speeds that I was and that they are more erratic on a speed test. Can anyone think of a reason why? This is my first nexus phone. I do have a nexus 7 tablet. I'm used to HTC phones and the nexus products seem so much easier or shall I say less complicated. Thanks to anyone who may help.

[Nexus 5 Android Development] jcsww:
I'd be more inclined to blame their tower than your device. My experience with Rogers hasn't always been a good one, especially when it comes to the Greater Toronto area. An unlimited Canada wide plan with 6GB of data shouldn't be hard to come by on most of the major carriers in Canada with Canada Wide roaming and calling. You will probably have to ask retention for it though.

Another thing to consider is possible sources of interference. Is there a new router close by interfering with your signal? WiFi Analyzer is a great tool from the Play Store to see what is lurking around that could potentially cause the signal to no longer reach your basement. I do hope the new phone does solve the issue for you though. If not, then try putting in a ticket with Rogers to have their techs come do a check on the towers in your area.
[Nexus 5 Android Development] leblvin:
I've got the exact same issue!

Anybody has a clue on how to fix this? I know we're at least 4 here on XDA reporting this problem in the last 2 days.
[Nexus 5 Android Development] xstokerx:
If I've lost your imei I don't think there's any way to get it back... I might be wrong might have to restore to stock and play dumb to return it just say it refuses to find the network
[Nexus 5 Android Development] leblvin:
Yeah, I think my only option is CDMA Workshop or QPST, put CDMA workshop costs like 100$ and I'm not even sure it'll work.

And I don't know how to use QPST, I keep reading though.
[Nexus 5 Android Development] jcsww:
After days of using hte .15 over the shipping radio, I have noticed quicker transitions from LTE to H+. In the two worst areas I am aware of here in Toronto for my reception, I can hold that last bar on LTE a lot better and H+ is definitely quicker.
[Nexus 5 Android Development] xstokerx:
Ya I just got this phone so imma see how rogers radio fair first then if its junk try different ones
[Nexus 5 Android Development] jcsww:
There is no Rogers radio from my understanding. They just resell the 16GB version of the phone to make money off of it. They don't brand or have any custom build for it.
[Nexus 5 Android Development] xstokerx:
O OK well what ever radio I've got I'll test then try others it did come with roger crapware on it though

Just checked ya .17 so ppl are saying there getting better reception with .15 on rogers?
[Nexus 5 Android Development] jcsww:
I am up in Toronto right now and find it works better for me than the .17 has, especially in the two areas I know of where my service is fairly weak.

Hi all,

So I'm using a D820 in the USA on T-Mobile.

Currently I'm on the .17 modem (which shipped with the phone).

I'm not having any issues per say... but i do see that the .15 modem has a later release date. Oct. 29 vs. Oct 11.

Should i flash the KRT01B or is this a mistake? Seems weird the radio would be going backwards as .17 is KRT16M.

Please and thank you advise!

Thanks for the cue! He doesn't do the Nexus 5 though, he'd need a special hardware equipment.
[Nexus 5 Android Development] bjbrickley:
I messed up my EFI... I broke the screen on my Nexus 5, got a new phone. Backed up everything, including EFI, and restored it to the new device without making a backup. Is there anyway to edit the EFI, or changed the MEID in the nexus 5 with any app?
[Nexus 5 Android Development] leblvin:
If you mean the EFS, that's what I've been trying to fix for the last 5 days, to no avail. I've been trying something new today, I'll post back if I find anything. But so far, unless you are VERY Android-literate, I suggest you don't even bother trying. You'll get headaches and probably end up screwing your phone even more. Wait until a solution arises, bring it to a repair shop that has an LG Octopus Box, or get an RMA if possible.

If you are VERY Android-literate, then know that the NV-items containing the MEID are locked, and that even if you restore your IMEI, the MEID will stay locked. You need to find a way to flash a modified EFS partition through the recovery, and I have no clue on how to do this. I've contacted the TWRP developper, but have no answer so far.
[Nexus 5 Android Development] bjbrickley:
Yeah I mean EFS. Im gunna call google and try to get an RMA. I just got this replaced phone today. Feel like an idiot... Shoulda stayed away from backing up the EFS, and restoring it. Shoulda made a nandroid before... ughhh shoulda woulda coulda.... If you figure anything out let me know. Thanks.
[Nexus 5 Android Development] autoprime:

[Nexus 5 Android Development] bmakk2055:
So the only way to mess up efs is by flashing radio's only?

---------- Post added at 05:47 PM ---------- Previous post was at 05:38 PM ----------

So you restored efs from another phone?
[Nexus 5 Android Development] leblvin:
There are many ways to mess up your EFS.

Flashing a valid radio for your phone is NOT one of them.

Restoring a EFS from a phone to another IS one of them
[Nexus 5 Android Development] bmakk2055:
Even roms
[Nexus 5 Android Development] IIMaxII:
Anyone try 0.12 or 0.13 yet? Also is there any new radios out? AOSP is on KRT16S already...
[Nexus 5 Android Development] leblvin:
If it is a valid rom for your device, theoretically, there is no risk to your EFS.

Things can always go wrong and I strongly suggest you keep a full backup of your phone both on it and on an external device.

I've flashed roms for years and my EFS was never corrupted.

I've got the flu and probably had no reason doing this with a fuzzy head and on cold meds, but I pretty much restored the EFS from my RMA Nexus 5 to the new one which I 'thought' but hadn't backed the EFS up from yet.

It's still no excuse, but that's how it went down.

How screwed am I right now?
[Nexus 5 Android Development] xstokerx:
no one has found a fix for this yet that we know of... hopfuly something can be done, the imei and a lot of the info is not backed up in anyway and once its changed its pretty perment I think.. its alos unique to each device sorry for the loss. I think the op should add a warning to the page about this as I can see it happing more and more with RMA's.
[Nexus 5 Android Development] LNJ:
I think this backing up of EFS is causing more harm than anything lately. It should not be part of a Nandroid backup. It should be backed up by itself once separately and stored away from regular nandroid backups.

[Nexus 5 Android Development] leblvin:
If you think that backuping EFS embedded in TWRP is a bad idea (or that its access should be restrained, or something like that), please show me some support on the official TWRP thread. I got the dev's attention, but I think he thinks I'm an isolate case. Here the link to my post, feel free to one-up me or add your comments.

And stay constructive, the devs can't be blamed for our errors. We use tools we don't fully understand/master and should stay aware of this. That doesn't mean, though, that such a powerful tool should be available to anyone.
