[Nexus 5 Q&A, Help & Troubleshooting] :
I've gotten 7 hours screen time...just....on my n5 now.

Any ROM, any kernel. ;)

People aren't going to want to "port" a kernel over....we have plenty.

The payoff would never come close to the effort and challenges. :)

I think its up to you! ?

---------- Post added at 10:30 AM ---------- Previous post was at 10:25 AM ----------

One more thing....people have tested battery changes based on kernel changes alone....nothing else changed, same usage......at best you might see a 5 percent difference in battery life.

So when people say, kernel does not affect battery life....they are basically right.

People constantly claim and try to get better battery life from kernels.....but its only cause they have unrelated issues affecting their battery, and have not addressed them....cause they don't know....or they don't want to put in the effort or sacrifice features to get better battery life.

Anyone that claims otherwise.... I'm sorry to say.....is simply wrong. :)
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
I understand all that now. Im not sayin anybodys wrong. All I know is, my first android phone was the HTC Evo 4G. That phone was such a big deal, it was kinda rediculous. There is alot of dev support for this, phone. There was even more for the Evo at the time. I mean, it was just crazy. I did a whole lot of testing over 2 or so years, so many different kernels. I remember, on stock, or most kerenels, that phone would die easy in half a day. Then one day, a dev by the name of Kingklick? or KingKlitch? something like that, had added BFS to his kernel and im sure other things. I kid you not that phone lasted for 2 days after that. Dont ask me why, I just know that it was because of the kernel, it had to be, I know i wasnt dreaming, or crazy. maybe its not that big of difference now because of these complex processors with 4+ cores and high frequencies, dunno, I just know that it did make a difference, back then, and it was big.
[Nexus 5 Q&A, Help & Troubleshooting] :
I agree....my S2 was much better with a good kernel, smoothness and battery. I think on the latest greatest phones, well I can speak for this and the Moto X....kernels may reduce heat, smooth things out (or make them worse if set too aggressively).... But they just don't really change battery life anymore....or even speed them up much. Under clocking is near useless now. And under volting is only helpful with heat issues.

Kernels have their place for sure on any phone..especially the features they offer over stock.....but I think the effects lessen as phones get faster and more optimized.

People would kill for a good kernel on older devices....that's for sure. :)

Well just for the heck of it I tried flashing back to stock 4.4.4 relocked the boot loader and tried a few downloads. Its still the same issue. I made a video of it. It does this completely randomly. It will be fine all day then just suddenly start doing this. Sometimes it does it all day. Let me know what you think.

Network issue: http://youtu.be/AMg8YfFUMx0
[Nexus 5 Q&A, Help & Troubleshooting] simms22:
wow, thats never ever happened to me. seems like it would be the networks issue(?) though.
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
well, im kinda hopin so, i read somewhere that the N5 has some "new" kind of LTE radio that is better on battery or something, maybe they just havent upgraded their network or something....?

Also, I've been looking at apn's and noticed that on slimkat, they apn's are different than on stock, on stock there is no user or password set, in slim there is. not that it makes a difference, but I cannot find an "official" tmobile apn setting for this phone.
[Nexus 5 Q&A, Help & Troubleshooting] :
Unless I missed something....it seems obvious to me. You're device is bouncing back and forth between 3g and 4g. You're right in an area between two coverage areas. (Or between a 3g tower and 4g tower or whatever) And its taking its time....likely a carrier issue, slow registering you from one band to the other.

It happens to me occasionally when I work at certain job sites.

I think forcing one band only should stop it...no?? Could try. ;)

Edit: yes, it can begin the switch from LTE say to 3g....but in the middle, register on LTE again. So it would seem like a disconnect for no reason....but really it WAS switching you from one to the other band....but changed its mind. Lol
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
Usually that doesnt happen, did you notice how it just went blank after the second download? thats what it usually does. If i try to force it to one or the other, it always changes back after a reboot. even if i use *#*#4636#*#* and set it that way. but usually it just cuts off like in the vid and a few seconds later it comes back on. sometimes it wont come back on at all.
[Nexus 5 Q&A, Help & Troubleshooting] :
I've had all that happen...a few times anyway....always when switching from LTE to 3g. Not so much the other way around tho.

I'd test by forcing one or the other and see if it still does it. Even if you have to set it after a reboot. At least to see if that's the issue.
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
well forcing it to lte doesnt fix it. just had it happen again. ill try forcing to 3g. also, i noticed when i relocked the bootloader and booted back up, i had no data, i waited a while and rebooted and it was back. just sayin.
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
im so tempted to take this thing apart and see if somethings loose
[Nexus 5 Q&A, Help & Troubleshooting] :
1000 percent sure your APN settings are right? Also....sim card issue maybe?

Gotta be something like that....pretty much ruled out software, since it doesn't matter what you run....its the same.
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
yup, Already tried a new sim card, got a brand new one a few days ago. not 100% on my apn settings, I dont know where to get an "offical list" and I've called t-mobile a few times and their very vage or they dont even know themselves:rolleyes:
[Nexus 5 Q&A, Help & Troubleshooting] simms22:
new radio is great on lte. i see around 5h sot purely on lte(i dont use WiFi, have an unlimited lte plan).

also, tmobile official apn for lte..
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
ya thats the stock apn it seems. ive tried em, i wonder why their different on slimkat. same apn, but there is a username and password and apn protocal is set to ipv4. whats the difference?
[Nexus 5 Q&A, Help & Troubleshooting] simms22:
dont know.

maybe someone working on slimkat finds it better for them? or maybe like on many roms, they think they are making an improvement, but arent. really, i have no idea.
[Nexus 5 Q&A, Help & Troubleshooting] Andromendous:
Well hopefully it is just the network, and they get it fixed sometime, thanks for trying anyway. Ill see if 3g makes a difference

While trying to do a factory reset (wanted to remove unuseful, old folders and start fresh with new ROM (p.s. now I know it was a wrong method)) accidentally checked all the partitions in WIPE section on TWRP. Thant included dalvik cache/cache/system/internal storage/data. Sadly it erased everything and now I am not able to put any zip to flash, since my pc doesn't recognise the phone. Now it is completely empty, only with custom recovery - TWRP. What should I do?

you must adb push or use USB OTG to get a ROM zip on your phone.

adb works in recovery

Hey,

i've got a Mobile Wifi Router from Alcatel, its nice and fast but the Webui is just crap. Its from EE (UK) and´they cut many settings out of the WebUI (5Ghz Wlan, Settings,...) so i want to mod it.

The Router got a SSH Server, but i dont know the login, some infos about it:

SSH Server: SSH-2.0-dropbear_2011.54

Webserver: GoAhead-Webs/2.5.0

Software Version:	Y855_E1_01.09_06

Device Name:	Y855

MAC Address:	24:0a:11:**:**:**

Android

maybe you got a idea how to access the filesystem (over usb, ssh or some like that) or give me some hints to test it out. Its this device (look at the attachment)

Thanks

[General Questions and Answers] cybermeow:
I found your post because I've recently been learning about analysis and vulnerability hunting on consumer grade devices like soho routers, ipcameras and as a customer of EE myself this unit caught my eye.

So my qualifications (and reputation) are low on embedded devices but if I had that unit on me and with the details you have would consider looking for vulnerabilities in both that version of drop bear and the webserver. Might be you could leverage this hxxp://xforce.iss.net/xforce/xfdb/73444 but that appears to be for privesc for a non-root user. I doubt heartbleed would work as they may not use OpenSSL.

I would focus on the Web interface. If you've and Web app pentesting knowledge then you'll be good to go otherwise it's not appropriate to try and do much unless you fancy learning.

Is it running Android? Could something like towelroot be leveraged?

I would also suggest popping some screws out and get some high resolution photos of both sides of the board. You never know they may have serial connectors begging for some headers soldered on.

These are the things *this* enthusiastic amateur would try.

Works for me, however only SSH, SFTP does not work.

You can enabled 5GHz on the EE Osprey using the javascript console on the WiFi settings page. Enter:

wlanModeGhz=1

countryCode="US"

submitValue();

Then click OK in the lightbox alert.

You should check you can connect via USB in case you can't connect over WiFi, on the Mac it involves running the WebApplication installer that mounts, then after some fiddling you can get 192.168.1.1 to load over USB. Try these settings at your own risk!
[General Questions and Answers] warwound:
I managed to enable 5GHz on my Osprey but that disabled 2Ghz.

I'd previosuly changed my SSID and after enabling 5GHz my SSID reverted to the Osprey's default SSID.

Changing the SSID in the wifi settings page does not change the 5GHz SSID.

wlanModeGhz default value is 0.

I set it to 2 hoping to enable both 2GHz and 5GHz but a value of 2 enabled only 2GHz.

Ideally i'd like both 2GHz and 5Ghz enabled at the same time - presumably the Osprey hardware can manage this...

And i'd also want to set the 5GHz SSID.

I've now reverted to the default wlanModeGhz value of 0 and will investigate more another day.

Y855 hacking

hey everyone, I've done some investigation on the OS of this device with the aim of getting off a usable full OS image or possibly just put something like debian or openwrt on it. I've found out the following:

1. All the MTD partitions can be read using dd, except partition 6. If you attempt to read this, the device crashes. It doesn't destroy the device, however, it just needs to run it's battery flat which takes 2-3 days. I got annoyed with mine and took it apart to disconnect the battery. On reboot, it works fine again. I'm still looking for a way to read that partition. Perhaps once I get a serial console working it'll give a hint.

Y855v serial console

I managed to reverse engineer the serial console on this device:

You'll need a 3.3v serial adapter. a Bus Pirate works great.
[General Questions and Answers] lomacks:
Nice! I'm about to crack mine open, so I'll have a go at hooking one up also...
[General Questions and Answers] lomacks:
I should have asked how you managed to get it open before I gave up and snapped it :) But in case this is useful for anyone else - you need to get a spudger (or screwdriver if you don't care about snapping it) under the thin glassy plastic top (right between the ~1mm thick "glass" and the bezel surrounding it), then start to carefully lift it and peel it up. Be careful as the plastic sheet is very brittle. Underneath are the screws holding it all tightly together.

Actually, it looks there's a small hole between the SIM card and SD card slots which goes straight through to the plastic cover on the other side that we want to remove - so poking something carefully up through there might help start it off.
[General Questions and Answers] lomacks:
sethp, quick question about the serial console headers you discovered (before I start soldering pins...).

Did you have to connect GND and Vcc pins, and if so, would you be able to point out the rails for me? (I'd start poking around with a multimeter, but I'm a bit of an electronics noob). :)

Secondly, what terminal settings did you end up using? e.g. 38400bps, 8 data bits, no parity, 1 stop bit, no flow control.

Cheers

Meanwhile I've dd'd a bunch of the MTD partitions off to the sd card to have a poke around... I'll reply if I find anything.
[General Questions and Answers] lomacks:
Interestingly, the device keeps working with the battery, antennas and the display disconnected as long as it's receiving USB power, which I'm finding a bit more practical when SSH'd in over the USB interface. (Obviously only useful for debugging, no good when you need the antennas!)
[General Questions and Answers] lomacks:
Weirdly, the maximum voltage I can measure anywhere near the UART/TTL points is 1.64V (about half of 3.3V); apart from the TXD pin you identified, which varies in the range 0V to 1.8V. See attached pic - I got a bit trigger happy and probed all over the board. I did find one 3.6V point fairly far away, but I guess that's probably a coincidence.

Would I need a lower-input-voltage serial adaptor (1.64/1.65V), or does the fact that TXD goes up to 1.8V negate that? In which case, any chance I'm somehow measuring it wrong?

One other thing I noticed that may be of interest - the lower-right probably-UART pin, labelled 1.64V with a (*) next to it, would cause the device to reset itself each time i probed it.

Thanks for any help/thoughts!

[General Questions and Answers] toxo:
Old thread but I have spent the afternoon fiddling and thought it best to write it down somewhere. If you want 2.4ghz and 5ghz you need to SSH to the device and edit a file. There may be an easier way of doing this like the Javascript hack earlier in this thread, but I've not figured it out yet as I was more interested in what I could do from the SSH prompt.

SSH to the device and edit the /etc/mobileap_cfg.xml file and set the <WlanMode> key to 'AP-AP'. This makes it configure 2 wireless interfaces on startup, 1 to run 2.4ghz and 1 to run 5ghz. You will find that you can only configure the 2.4ghz radio from the web interface - the 5ghz radio is configured by the file /jrd-resource/resource/wlan/ap_wlan1.conf - you will at the very least want to enter your country code in there to get the right 5ghz channels. This makes a much bigger difference on 5ghz than it does on 2.4ghz.
