1- if charger has low efficiency the loosed energy will turn to heat on charger. Generally efficiency is near 80% and it translate to near 2~3watt energy loose on full power. It will heat this little chargers very fast.

2- if the cable is too thin or connectors oxided, power loose on cable will heat cable, charger also phone. If the problem is cable charge time will decrease when cable heated. So if your charge time is ok, problem is dc-dc convertion efficiency.
[Galaxy Note 3 Accessories] recDNA:
You mention low efficiency getting charger hot. It wasn't., nor was the cable. Only the phone was hot.

[Galaxy Note 3 Accessories] kadiremrah:
chargers output voltage and ripple must be measured.

Voltage higher than 5.5V or voltage ripple can cause this. Charger voltage can ripple from 4V to 6V and you can only measure 5V avarage voltage with standart multimeters. Be carefull and do not use that charger.

I rooted my phone, then I proceeded to delete some useless system apps that were taking up space, I somehow delted an AI app in this process, so I decided to recover my phone using another ROM. I may have accidentally formatted the internal storage, now the phone is stuck on the turn on screen whenever I try to turn it on. Is there any way in re-install android or something?

If anyone gives me a solution that works, I'll send them a 20 dollar visa gift card in the mail.

i mean s116 not 166 lolz
[Shield Q&A] bl00dy:
is that possible? i can't see the kernel panic i'm getting...get a bunch of 'CPU X stopping ... swapper not tainted" errors that flush the screen

if i boot with kernel and no 'root=mmcblk1p2' i do see a 'mmc -110 error' which i've read is a timeout, and it goes to the internal mmc

and i see there are ppl complaining about sd problems on here...

using a 'sandisk pixtor 32gb' (class 10) - don't have a card to test if it's the card

update - cmdline 'maxcpus=1' ftw

'initramfs unpacking failed: junk in compressed archive'

and not mounting like i thought

'mounting /dev/mmcblk1p2 on /newroot failed: no such file or directory'

update again - no sd

edited init to ls /dev...no sd card under there...not sure what the initramfs error is but i'll ignore it..

would still like to know if anyone has had success (maybe w/ a diff card?) booting on SHIELD
[Shield Q&A] Gnurou:
Booting a userspace stored from a microSD is possible, yes. However, the kernel itself must be on the internal memory (or sideloaded using fastboot). SHIELD's bootloader does not support booting a kernel directly off a microSD card, unfortunately.

The CPU errors are because Trusted Foundations support is not enabled in your kernel. It is required for booting secondary CPUs. What kernel are you trying to boot? Android or Linux? Which branch?
[Shield Q&A] bl00dy:
it seems even with the newer 'roth_next' kernel - sd still doesn't seem to show up at boot

going to guess that it's my card...

if anyone can test the steps at https://github.com/linux-shield/kernel/tree/roth_next and edit the https://github.com/linux-shield/bbinitramfs init to 'ls /dev' (if you mount a bogus root it will fail) to see if you can notice any other mmcblk# - that'd tell for sure

going to see if i have a non-sandisk laying around and test if it will show up
[Shield Q&A] Gnurou:
What type of SD are you using exactly? (SDHC, XDHC?). For use with upstream kernel I would not go beyond SDHC 32GB.

The steps on my Github page should be correct, I did them myself many times. The initramfs can be a pain in the ass sometimes, I did it for people who want to be able to keep using Android. If this is not your case, and you don't mind borking your user data partition, you can put your root filesystem on /dev/mmcblk0p12 and boot directly to this (root parameter of the kernel). This gives the best performance and is the easiest to set up, but after that Android won't start.

Then if you have a USB network adapter that you can connect to a hub along with your keyboard, you should be able to import stuff easily to your SHIELD's root (without using SD), using just rsync. This should be more comfortable than using a SD card as root, actually.

Anyway, your SD card should at least show up as /dev/mmcblk1 when inserted after boot. If you want to validate it once and for all, try the following:

- boot using my bbfs (not bbinitramfs) filesystem using fastboot (fastboot boot zImage_dtb ramdisk.img.gz). This will get you to a shell without any physical storage mounted, and you will be able to use a USB keyboard.

- insert your SD card and wait ~5 seconds. Check that /dev/mmcblk1 had been created.

- if not, check any kernel error message using dmesg.

By the way, have your problems with CPUs been solved by using tegra_roth_defconfig? Are you able to see all 4 cores now?
[Shield Q&A] bl00dy:
All 4 cores was the problem in (not) seeing the init failing to mount root (it flooded 'CPU X stopping' - 4 times)

I believe my sandisk is SDHC (UHS-I <- that's an 'i' )

Looks like the problem is my card - found some 4GB (lower speed i'm guessing) and i do see a mmcblk1 and 0 (1 being my card, 0 being internal) at boot. Also my other sandisk card (16GB) does not show up; it is the same type of card.

Guess i'll have to nuke and backup the android partition =/ or eat the money and buy a different card and hope it works...(16 should be fine for almost everything, but 32 leaves space for compiling some bigger programs, which i really don't need i guess...)

My keyboard doesn't work when i plug it into the usb with a female converter (SHIELD > microUSB cable > female-female < keyboard) think i need a USB OTG cable. Once i get that i can login to gentoo and try to mess around
[Shield Q&A] Gnurou:
Yeah, you will need an OTG cable to get your keyboard to work. I suggest connect the OTG cable to a self-powered USB hub, and then plugging your keyboard, mouse, and network adapter there. If you get a powered OTG cable (like this one: http://www.amazon.com/Estoreimport-Micro-Cable-Power-Samsung/dp/B00C4521R4 ) you should even in theory be able to charge your SHIELD while using all these peripherals by plugging the big male port into your hub as well. But that will require another patch to the kernel - I plan to get this done at some point, just not immediatly. :)

I *think* Android will work just fine with a Linux root filesystem on your (ext4-formatted) data partition, it is just going to put its own directories in there and you will end up with Android directories at the root of your Linux filesystem. If this doesn't bother you, this is also an option. You will have to reformat your data partition to ext4 in any case. SD card support is kind of unreliable in my experience and also slower than MMC, unfortunately.
[Shield Q&A] bl00dy:
T_T *sigh*

so got my OTG...keyboard = awesome, rt28xx (alfa) wifi works

but reinserting my SD UHS, just results in the same -110 error about failing to initialize. still the same only mmc0 in /dev

i don't think the tegra SD drivers are working, but i don't do a whole lot of driver programming.

clearly the card works in android. so comparing the 2 drivers may help me understand. but i'm going to bkup and nuke the /data and install there.

so in the end...32GB card is good for backup..not that i 'need' to do that
[Shield Q&A] Gnurou:
Yeah, the upstream SD driver is clearly behind the Android one. :( That or I did a poor job in the SHIELD's device tree.

Well, actually since you have a USB hub, and USB works at boot already, you can also use a USB mass storage device as your root filesystem. That would certainly work and you won't have to bork your /data partition.
[Shield Q&A] bl00dy:
not sure what it is, haven't looked.

nope...used and mounted as sda - was a PAIN. anything mounted on USB OTG kept getting errors and saying it couldn't be read

so i eventually found a card i haven't used in forever...cp'd my root.img gentoo to that. cp'd that sd card to mmcblk0p12. finally after hours of moving data around i got a functional booting shield...

but of course like you said, it doesn't charge while running, so i have to keep moving the keyboard/power around. it dies in the middle of compiling and it doesn't like that =/

i'd distcc to make it faster...but i want to make sure it doesn't die. so i'll leave it on power and wait overnight to see what all it can compile
[Shield Q&A] Gnurou:
It should be possible to charge your SHIELD while using it as a USB host with a Y cable to provide power to the SHIELD and some more kernel hacking. Let me know if you really need it, if so I will try to find the time to implement it (it should work *in theory*, but no guarantee of course).

---------- Post added at 11:15 AM ---------- Previous post was at 11:11 AM ----------

Actually if you have such a Y cable, try to connect it so the SHIELD gets powered - it might be working already since the orange led lights up when you do so. I haven't kept mine long enough in this situation to know if this means the battery is actually charging though. :silly:
[Shield Q&A] bl00dy:
hm...

so i'm looking at the dev tree...

/* SD card */
sdhci@78000400 {
status = "okay";
bus-width = <4>;
vmmc-supply = <&vddio_sdmmc3>;
cd-gpios = <&gpio TEGRA_GPIO(V, 2) GPIO_ACTIVE_LOW>;
power-gpios = <&gpio TEGRA_GPIO(H, 0) GPIO_ACTIVE_HIGH>;
};

and i found a few things...like http://comments.gmane.org/gmane.linux.kernel.mmc/21564

and https://en.wikipedia.org/wiki/Secure_Digital

which says...

i'm guessing that's why my card wont work?

have things compiling right now... but i figure i dont mess with low level kernel that much. may want to make sure it looks right to someone who knows more

update:2-4-14

well looked like everything compiled last night. even though i forgot to plug the power into a socket x-x

did edit the .dts and added some of the lines from that link, didn't really do anything. i figured it was worth a shot...

update : 2-4-14

looking at my android dmesg i saved

<6>[ 2.598398] mmc1: new ultra high speed SDR50 SDHC card at address aaaa
<6>[ 2.598778] mmcblk mmc1:aaaa: Card claimed for testing.

<6>[ 5.457720] SDIO Vendor ID:02d0 and SDIO Device ID: 4324

looks like my sandisk and the wireless are UHS speeds...so...that would explain why neither seem to show up except a 'fail to initialize' error
[Shield Q&A] Gnurou:
mmc1 shows as UHS in your log, and I'm pretty sure the driver can handle the drop to 1.8V (IIRC).

On other boards this driver is known to work fine (if a little bit slow), so I really don't know what I screwed up here.

I find it surprising that you are having issues with USB mass storage devices. I really don't see what could go wrong, at least if they are powered externally (i.e. behind a self-powered hub). Could you maybe post the relevant logs?
[Shield Q&A] bl00dy:
here's the dmesg i was talking about

http://pastebin.com/r0uv97Up

as far as linux..there's nothing else to show, nothing shows up. it's like the UHS devices don't exist

IIRC, used tegra defconfig and may have added some crypto/fs' or something...but didn't take anything away. edited the cmdline for boot in .dts

edit:

that linux dmesg was before i put things on internal /data. think it's the same though info though

edit:

http://pastebin.com/agdi1CVR

turned on mmc debug...don't know if this helps. basically keeps looping while the UHS SD card is in.
[Shield Q&A] Gnurou:
Mmmm yeah. I'm afraid I'm clueless here, at least until the Tegra MMC driver gets an update. :( Sorry.

no problem, thanks for taking the time.

Hi I'm new on here so I hope I'm asking in the correct place!

I have two questions, firstly my RAZR HD has jelly bean system version 98.21.26002.XT925.Orange.en.GB

It states on the Motorola website that only phones running a retail version will receive the ota upgrade to kitkat....

Now it seems I don't have a retail software but there is no retail software for the uk RAZR HD just the orange software so is this the retail version and will I receive the ota upgrade eventually for my razr HD ??.

Hope someone can help thanks.

maybe moto would make a retail ROM and then pass on to carriers to customize? I'm not so sure,

"Confirm you have a Retail model. Go to your device’s Settings menu and select About Phone. If you don’t see Retail (or RET) under System Version, go back and select your carrier."

if you really want kk when its released just flash it...

[HTC One X] teoB_Glar:
Hi,

I've been a galaxy s3 user for long,and recently swapped for a hox. (always a HTC fanboy). Anyway, does anyone know if there's a kernel with touch2wake feature after screen is off? I generally read a lot and is quite useful mod. I don't mean slide to wake (=to lockscreen) but while you're reading something and screen sleep timer reaches its value , a single tap at screen lights it up again. Thanks in advance for your answers.
[HTC One X] donkyshot:
I'm not sure about single tap, you mean screen off? Depending on your Rom there are different kernels with double tap to wake and sweep to wake. If you mean you want the screen to light up when it starts dimming, a single tap should reactivate the screen on any Rom I can think of. You can set your lockscreen time if it's too fast for you.
