/data/media/ is also /sdcard/

seems something isn't getting symlinked properly. but normally "sdcard"s REAL location is /data/media... so not so weird that it's there... more weird that its not also showing up under /sdcard/

good to know tho.. maybe this will help others who couldnt find it. :good:

Assuming that I made a backup of the EFS and moved on pc..

When i install a new ROM the procedure to be followed is: wipe data/factory reset, wipe cache, wipe dalvik, and wipe system.. right? then flash Rom and ecc...

Ok..but..

the EFS folder is deleted (with all wipe)? or is in another partition and then is saved?

Sorry for stupid question.

So is there international/US versions of the Nexus 5 or is there just one? Trying to understand the difference between the modems (same file, different bands?)

[Nexus 5 Android Development] adriangb:
Cool, so my US variant has all the bands I need for my travels to argentina (LTE 7 & 4, HSPA+ 850Mhz/1900MHz)
[Nexus 5 Android Development] autoprime:
if you do a data format.. it wipes /data.. including /data/media(sdcard)... so yes if you did that itd wipe efs backup.

if you just do a normal data wipe(in twrp.. hit wipe then swipe slider across).. then that shouldnt touch the efs backups.

Any comments on radio performance ATT straight talk

Not getting much difference in overall radio performance except that .17 may avg slightly better, but has a higher variance which could be more dropped calls...think i have to find an app to track averages with standard deviation?. Sucks that ATT/straight talk is great all over miami except for in my bedroom...

it does seem that that after rooting and messing with it signal performance is alittle worse, but i have checked all my apns and radios so i am not sure what it could be.

just need to find a way to milk a slightly better signal in my bedroom as it seems that once every 20 mins i loose a call, and i love working from bed lol :)

sorry if this is all to vague not really sure where to go from here might try flashing back to stock and starting from scratch again.
[Nexus 5 Android Development] cavedano8:
I'm sorry, I have not explained well.

I meant the original EFS folder.

With all wipe (data,cache,dalvik and SYSTEM) i lost the original EFS?

could you help me ? if i choose "only GSM" it says "0 bar signal and signalstrongh 0", when i go to #*#*4636#*#* it says "unkown network"

IMEI is present and the right one but why it will not connect on 2G :c ?

Edit:

ok about 20m under the signalturret i got full strengh on signal bar and finally 2G

but if i take some distance. like 150meters , i got 0signal BUT STILL "80dBm" on status ?!

wtf is going on? is it and hardware bug or software ?!

it only connects on HSDPA/UMTS and LTE , but the strange thing is that if i go under the sending turret i get "90dB" and EDGE works... it works in a ratio of may 100-200meters and than again "0db"

Might be a dumb question, but regarding back up of EFS partition , does it make a difference if the back up is from a custom ROM. I started flashing custom ROMs and kernels without a EFS back up, i do have a back up of the original ROM. I backed up EFS via TWRP, AND flashable zop that creates a flashable back up f the EFS. So my question is if I have to back up the EFS on original ROM or it doesn't make any difference?

I don't have a nexus 5 to test this, but this command should work to patch the previous radio:

bspatch radio-hammerhead-m8974a-2.0.50.2.25.img modem.img radio.img.p

Where:

- radio-hammerhead-m8974a-2.0.50.2.25.img = radio image from LMY47D/I factory image
- modem.img = radio-hammerhead-m8974a-2.0.50.2.26.img (after patching)
- radio.img.p = patch from LMY48B OTA

After patching here is the LMY48B radio in image (fastboot) and recovery flashable formats:

I'm not at home now. You can extract all the bootloader*.img files from the newest OTA zip file, then take any other old bootloader flashable zip and just replace the img files of that zip with the newer ones.

The zip now will flash the new bootloader.

That's why I still use KRT16M radio. Every LP radio on LP rom gave me higher idle drain. No wakelocks at all, unexplained drain only. One day I kept LP rom and reverted good old KK radio I used before to see what will happen - bang! Idle drain is gone.

On the other hand, old Slimkat setup gave me slightly better battery performance but I decided to stay with LP due to other features.

First of all thanks for the awesome thread and collection.

I have to say that I'm also getting some higher drain with the latest 2 L radios. Not really sure why. So I'm gonna try the old KitKat radio that everyone seems to be raving about.

Would be good to hear if someone living in London area and on Three network has good experience with a particular radio.

[Nexus 5 Android Development] CamoGeko:
Yes you can do it, but your boot loader has to be unlocked .
[Nexus 5 Android Development] CamoGeko:
I've tried this radio indeed, and it gives me less drain and stronger signal that all L radios. -99 DBM vs -85/-95 DBM. Even the LRX one has the lower strength.

However, the kitkat radio seems to be rather slow at switching and latching on to 4G signal than the L radios. Further testing is needed.
[Nexus 5 Android Development] Phazmos:
First thing I noticed when running lp with kk radios. Took forever when switching from wifi to cell data.

Lrx and later would take 3-5 seconds. Anything earlier would be minutes, if it connected at all.

I guess there was a good reason Google updated the modems with the updated os.
[Nexus 5 Android Development] CamoGeko:
I'm in London on Three network and so far the L radios give me better speeds but more drain and lower strength signal. While the older KitKat radios give me better signal strength and lower battery consumption but slower speeds.? Also KitKat radios seem to be slower at finding and latching onto 4G signal.
[Nexus 5 Android Development] Phazmos:
US, ATT, and I'm in the sticks.

Never notice a difference in battery life - speeds are kinda hard for me to tell. Besides the mountains and sparse coverage at best, att is over saturated around here. Best I can say about speeds are they go up 2-3 fold after about 1 am, and start to crawl again about 5 am.

I guess that's the price to pay for living in the country, but I wouldn't change that of I could get a 100 gig connection!
