[EVO 4G Q&A, Help & Troubleshooting] zincfinga:
I was able to unlock the bootloader following the instructions on HTCDev. However, I am now unable to install a custom recovery. I have tried using both the 'fastboot' and the 'PC36IMG.zip' methods with the 'AmonRA-v2.3-hausmod_revA', and the 'PC36IMG_ra-supersonic-4.3-smelkus-ics',

When using the Fastboot method the recovery seems to flash, but afterwards, when I navigate and select 'recovery', the device sticks in the splash screen that reads 'htc EVO 4G'.

Here is the Terminal output from an example:

c-s-MacBook-Pro-15:~ c$ fastboot devices

HT08******27	fastboot

c-s-MacBook-Pro-15:~ c$ fastboot flash recovery PC36IMG_ra-supersonic-4.3-smelkus-ics.img

sending 'recovery' (4140 KB)...

OKAY [ 1.475s]

writing 'recovery'...

OKAY [ 1.775s]

c-s-MacBook-Pro-15:~ c$ fastboot erase cache

erasing 'cache'...

OKAY [ 1.227s]

finished. total time: 1.227s

When I use 'PC36IMG.zip' file to the root of the SD method, I get 'main version is older. Would you like to reboot?''

If I change 'mainver: 1.00.000.0' to 'mainver: 4.67.651.3' in the 'android-info.txt' file inside the zip (like suggested elsewhere), I get 'Parsing PC36IMG.zip...', then nothing.

It does read 'ÚNLOCKED' at the top of the bootloader screen now, and I checked md5 sums.

Any suggestions or help would be appreciated.

The Phone no longer boots up properly. Sticks in boot-loop when not booting to bootloader. It's a Sprint device. Was having issues with seemingly random powering down. Was able to boot after unlocking bootloader, but now doesn't (may have úninstalled' necessary 'bloatware').

Hi,

I was able to root and install recovery to HTC sensation, and was able to flash bricked kernel (Bricked-3.0-v1.4-ics). But after flashing the kernel, wife would not turn on. I tried factory reset, but still would not work. Any solution? IMy phone was in the stock rom with sense 3.6, HBoot 1.27. Any help would be really appreciated.

[Motorola Atrix 2] darksurfr:
I posted this in the N00B question thread but I was told to make a new thread.

So my friend got an Unlocked Atrix 2 and she is using it on T-mobile. When the sim is inserted she can make phone calls and send text messages but it says the sim card is full and it wont let her import the contacts from the sim card to her google account. In fact it says there are no contacts but that is definitely not the case because if you put it into the old phone they all show up. That being said I found a thread that apparently has the answer but I don't know what exactly I am supposed to do. Am I going to have to root the phone so that I can modify the XML system files?

Thread with supposed answer

Why don't you use the old phone to sync contacts with Google, then login with the same Google account on the new phone and sync again.

On the S3 I believe there were a couple if mods for multi window that allowed other apps to be used other than the ones restricted by the device. Is there anything like that for the S4? To the great developers out there can we get something like this?

[NFC Hacking] compuw22c:
I have a project (NFC Vending machine) based on Arduino which calls a function called nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A)

Which returns a simple UID of the device that is tapped to the NFC antenna. This is used to identify the user, display their name and account balance, relay to coin acceptor and then saving the new balance back to an SD card.

This application works perfectly with my Nexus 4, a friend's stock Nexus 4, as well as any NFC Tag.

When I try using a new Galaxy S4 however, the application finds an ID from it, however it CHANGES every time it's scanned? Does anyone have any idea how to stop this from happening? I'm not opposed to writing an app if I can write an app that stops this from happening (some function in code that can set the UID to a static unchanging value, maybe using wifi mac address as a base)?

When I try scanning a co-worker's Droid DNA, NOTHING happens. NFC is on, beam seems to work, but nothing happens. I'm wondering if I install an app that reads/writes cards and tell it to perform an activity maybe that will 'wake up' the nfc chip making it active and forcing it to spit out an ID?

I have a feeling I'll have to use an "if id is not found, try ndef" and write an app that can send an ndef message that is the wifi mac address (so it'll be unique), though I haven't done much in the way of app development, though I'm very familiar with playing with all kinds of nooks and crannies in the filesystem to do fun things in android. I'm not opposed to learning, and have been trying, just not too familiar with java which certainly doesn't help... In any event, I'll be diving in and punishing myself with more hours of reading soon...

I realize this is a rather unique project and I may not find a resolution here but any ideas anyone can offer would be a big help. In the meantime I'll continue reading up on the various actions that are available to the programmer regarding nfc in the android sdk...

Thanks for any suggestions!

EDIT: I forgot to add, while I realize NDEF is an option (one that will require me learning a fair bit), it adds a great degree of difficulty in working with Arduino, which doesn't seem to have much in the way of libraries/code for handling NDEF, particularly peer-to-peer...

[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.

For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?

First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).

Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).

Mine lately, say if I had it charged at 100% , it'll take about 2 hours on mobile to get to 91%, with the screen being on about 25%-35% of that time (auto-brightness), receive/send text, take out of pocket to check email or facebook notifications, and so forth. Which would normally show as screen 30%, Google services 13%, Wifi 9% (when I had it on between house and destination). Phone idle 8%, Android OS 7% etc.

The widget I mentioned earlier can basically monitor your draw from time to time and if the screen was off or on and such during those times (default interval on it if using a widget is around 10 minutes on the logging, shorter may actually impact the battery it's monitoring oddly enough)

PS: The other day when I actually drained it down to 0% it took about 5-6 hours
[Nexus 4 Q&A, Help & Troubleshooting] scream4cheese:
I had about 3-4.5 hours of screen time other moderate to heavy usage on my first week as I was testing it's battery life. As that I just used my phone under light to moderate usage. My brightness level is always at it's lowest but when I'm outside I turn it up to about 50%. I rarely play games on my device. I read a lot on my phone. I use my phone to record lectures in class and do a bit of homework on it. 7 months later and I'm pretty much doing the same. I have a custom kernel installed and I'm really confidence about it. I carry a external battery pack with me all the time but I hardly use. After having a custom kernel for the past 7 months I can say battery life has been relativity the same screen time wise. I learned how to manage my apps so they won't prevent my phone from sleeping to save power. Your mileage will vary depending on what you're doing on your phone and how you manage your device. Cell service is crucial to the phone. If you're in area with little to no service your device will use up more power to stay connected. This is when "Airplane mode" comes in handy.
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Nah. All stock, not rooted yet, auto-brightness, No auto sync. I don't get very good service at my work and I was about 28% without service during the time I was there. I would get on facebook and message people on facebook and text, surf the internet etc because it was slow. I had maybe 2 hours screen time and 8% battery life when I left work. It was probably 9 hours off the charger. Here. I'll post a screen shot after this post (On my computer right now)
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
One of the benefits to custom roms (though 'stock' on a nexus is well AOSP so...) is the ability to tweak that stuff to finer details, top it off with a custom kernel and can optimize even further. Just a matter of how far you want to take it.

I have a history of immediately rooting anything I get my hands on, so I tend to have very little experience with stock. But the Nexus devices are probably the only ones I could survive having stock (but rooted) as opposed to say touchWhiz on samsung. :P
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:

[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
:P At least all the available kernels work just fine with AOSP. (Francos seems to be pretty popular for battery, I prefer bricked though on both my N4 and N7).
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Why do you prefer them?

So with battery monitor widget pro do I just let it run and collect data?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Guess tonight I'm going to work on getting it drained down to 0% just remembered it was my N7 that I did a full cycle on with monitoring, I haven't done so yet to the N4.

PS: I usually do a dual-graph (mV and mA), but in this screenshot you can see generally speaking with my current configuration, I tend to drain around 200-300 mA screen on, and around -20-50 with it off.

PS#2 : It only went up to the -400 or so mA on the top right because I had changed my screen brightness to about half instead of autobrightness.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Additional options. Take for example the Bricked kernel for the N4 in my signature. This is it's feature list, it's not aimed for hardcore overclockers or such but gives you some options (The one for the Nexus 7 is a bit more configurable during the installation).

Sweep2Wake is kind of nice too, you just slide accross the screen to turn it on without having to touch the power button (And yes your phone is still asleep doing this, it just works off interupts.)

other kernels can be a bit more involved, such as being aimed towards overclocking the CPU or GPU, or adding in extra features not normally found in stock, and so forth. I've had the best luck with Bricked and Francos'

Yep, if you have a widget on the home screen (I usually do 2x1 size) it'll collect every 10 mins by default. If you don't use a widget you'd have to check a box in preference to monitor without widget or it won't log times (note for example the missing 'blocks' from my history log).

---------- Post added at 11:29 PM ---------- Previous post was at 11:22 PM ----------

Speaking of battery, anyone ever gotten more than say 800mA charge on their N4? Cuz even on my old Desire-Z if I plugged it into a 2.1A charger it would actually charge up around 1300-1500mA, but with the Nexus 4 seems that even on a 2.1A port it rarely charges more than 500-600mA.

It'll probably become more accurate once I actually drain it down to 0% and have the widget record it's history from 0% to 100% since it bases a lot of it's mA estimates off that (ie: off the rate of decrease of the battery's mv since batteries typically have a certain voltage once they hit near 0% and when they're at 100%, comebine that with what it knows the battery's mA to be it can determine the charge/discharge based off that).
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
I can get back to you when I figure this app out more and start using it.

What'd you say your screen on time usually was?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Just in the last 2 hours or so, probably 30-45 minutes. I was in the car so it wasn't coming on all that often. Since I actually have the widget on my home screen now, I'll just post an update again probably in the morning as I play with the phone some more, maybe play a game or two (I'll set a Market in the battery history before I start and after I end it).

Far as figuring it out, it's pretty easy since most of it is already set up by default once you open it. You can basically just pop a 2x1 widget on the home screen and just leave it.
[Nexus 4 Q&A, Help & Troubleshooting] nyyankees1237:
My battery life has improved drastically by just sticking with one setup and letting the phone get used to it. That means keep the same rom and kernel so the phone settles in and gets used to it. After a few cycles your usage should increase.

I recommend straight CM 10.1 with Franco kernel.

Also use 2g instead of HSPA+ when you're not using data to save power.

If you're using touch control, don't, it drains more power for sure.

Undervolting helps too.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Can you clarify on this, other than the power/volume there's not much else to actually control the phone with.
[Nexus 4 Q&A, Help & Troubleshooting] nyyankees1237:
The app 'touch control' , many nexus 4 owners use it to wake and lock the phone using touch gestures in place of the traditional power button. In my usage it definitely drains the battery quicker.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Oh you mean like Sweep2Wake in the Bricked Kernel I'm using, except that doesn't use any battery cuz that's in the kernel using interrupts rather than an app that would keep the phone awake. (course that's all it does too, wake, nothing more sophisticated than that).

But yea I didn't know about that app.
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
So yeah. You should drain it then report with some screenshots.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
It's at 44% right now
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
screenshots?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
It sat mostly idle last night, (I was also checking to see what the power draw of the broad-cast only patch was since the Nexus 4 has a push notification bug with the screen being off, so far around -40 ish draw instead of -27)

This is screenshot so far, and I'll re-post once I get down to around 0% , and then charge up again.
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
So over night it dropped that much?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
That's a 2 day graph.

It was about 92% at 10pm last night, it's now 38% at 3:14PM that's about 17 hours there, mostly screen off. So not sure what you mean by "that much".
[Nexus 4 Q&A, Help & Troubleshooting] WiseManWhite:
Your usage, set up and battery life results are identical to mine haha. I don't know how people get 3 to 3.5 screen hour time.
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Oh I see.

Also, on the graph, is there a way to see the number on each hour?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
I'm assuming each block is about an hour, I haven't seen anything in the settings to put a bar per block. also along the bottom of the graph are yellow, that's a screen on indicator. Same as the yellow on the left side of the interval listing (which is done every 5 minutes).

Attached are the screenshots I took a few minutes before the phone died from running out of battery. I'm currently re-charging it (it's at 85% now).

Edit: By the way if you mean the battery %, that's on the left side from 0 to 100% (though with my miliAmp graph it won't show that).
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
And here's the final graph after I got it charged up (initially at home, then popped it on a car charger, then in mall, then back on charger at home).

Charging started around 800mA dropped down gradually as it got higher. (700mA ~ 60%, 300mA ~ 90%, 146mA ~ 95+%)
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
I gotta learn how mA's work with battery.
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
Well not that hard really, least in the sense of what it means

-##mA the lower the number is (ie: -100 is lower than -50), the more of a drain the phone is having.

+##mA the higher the number (+100 > +50) the more of a charge it's getting.

With a 2.1A charger on say a tablet, it's possible to get up to around 2Amps (500mA = 0.5A), the higher the amperage is for charging, the faster the battery will get filled, likewise the less into the negative it is, the faster the phone's battery is going to drain.

I usually use the mA reading to get an idea of when or what is draining the most from the battery, or how much of a drain.

I know that when I use the work-around to fix the push notification bug the Nexus 4 has (that google still hasn't fixed), I'm using almost twice as much power in sleep mode (ie: around -20mA used in sleep versus to around -40~60mA in sleep), so from that I can make a decision of whether or not I want to use the work around, or if the benefits outweigh the cost.
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Why am I I'm the negatives while it's charging then?
[Nexus 4 Q&A, Help & Troubleshooting] Beerad875:
Why am I in the negatives with it charging then?
[Nexus 4 Q&A, Help & Troubleshooting] kbeezie:
I noticed you're in the positive when your screen is off (faint yellow means you just had the screen off)

Means your charger isn't putting out more juice than the phone is charging.

So for example if you're using a generic charger that says something like 5V 0.5A , and your phone is using 1Amp of juice, it'll only show about -500mA. But if your phone was using only 500mA and the charger is 1A then you'd see something like +300 to +500.

Most smartphone chargers are 1A-1.2A, the one that comes with the Nexus 4 should be 1.2A (should say on the charger itself).
