I actually already had a external battery charger for my phone! I completely forgot I had it hahah!! :) I'll use this method until I can get an upgrade in August. Thanks everyone for your help :P
[AT&T Samsung Galaxy Note I717] johnny grep:
Hello,

I have a Bell Samsung Galaxy Note which had Gingerbread but could not find the OTA upgrade to ICS for some reason. It originally had ICS but flashed it back to Gingerbread since I wanted to start from scratch (using Odin). I've had numerous issues flashing it using Odin (many nand flash errors, soft brick, etc) but now I flashed it to AT&T stock, just to test if everything was working. All is good for now.

I want to upgrade it to ICS to perform the T-mo unlock trick but everytime I try to flash an Odin ICS tar, I get hit with an error at some point and the phone puts itself in Kies recovery mode (Firmware upgrade encountered an issue). Here are my questions:

1. Upon flashing an ICS tar in Odin, should I select the re-partition option in Odin (e.g. does it have a PIT file in there)? Or can I just go ahead and flash the tar file under PDA?

2. Should I do a factory wipe on top of the cache wipe in recovery before flashing an Odin tar?

3. Are there any OEM stock images/ROMs (AT&T, Bell or other) that can be flashed with a cwm/twrp recovery? All I can find are tar files, I know I can probably modify them and remove the recovery.img but would rather not as this might break things.

4. Any issues flashing through VMware Fusion on a MacBook Pro? Could this be the cause of my issues?
[AT&T Samsung Galaxy Note I717] HD2FORNICK:
A few days ago I purchased a ATT i717 locked and used the TMO Radio to unlock it as described in a unlock sim thread. I then installed an ATT ROM and am actually using it with a metropcs SIM card.

I began by originally using odin to root and install touch recovery. I somehow got stuck on the SAMSUNG logo but was able to get into recovery and flash the goldie rom. Since then I have installed a kit kat rom and everything is fine.
[AT&T Samsung Galaxy Note I717] johnny grep:
FYI, if anyone is wondering, it was VMware Fusion causing interference - I later found a reference to it on another xda post while searching for something else but it wasn't that easy to find. I have another MacBook with Boot Camp and that one can flash through Odin without any issues. So if anyone is trying to VM their way through Odin flashing, it's a bad idea. It'll stick your phone in recovery mode. Since then I've flashed/restored many Odin files, reinstalled cwm, flashed a few roms including Custom Canadian JB, Padawan JB 4, AT&T Stock, etc.

So my wi-fi speed was awfully slow on my razr I, I started diggin on the settings and I managed to improve it a bit by changing the channels on the router, but still, compared to my desktop pc, and my friend Iphone 4s, I only get half the speed!! (12bmps vs 6bmps), I'm the only one with this issue? any idea how to improve it? I'm on stock 4.1.2 retail br.
[RAZR i Q&A, Help & Troubleshooting] pirast:
I get 10/1Mbps when using my Razr (tested using "Speedtest" app) and 30/1Mbps when using my laptop. They are both connected using Wifi and are in the same location. Sadly, I can not tell you how other smartphones perform in my environment.
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
It should perform as good as your laptop, guess I'm not the only one with thar issue.
[RAZR i Q&A, Help & Troubleshooting] pirast:
I've made another observation. My wlan ap shows a gross bit rate of 72 Mbit/s for my razr and of 130 Mbit/s for my laptop.

It (kind of) reflects the relative performance difference I get when comparing the devices - so maybe the Razr just has a bad antenna?
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
what app did you used? its quite strange tbh, hope we get some more feedback.
[RAZR i Q&A, Help & Troubleshooting] pirast:
Its called speedtest.net
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
this one? I can't see that "gross" speed anywhere
[RAZR i Q&A, Help & Troubleshooting] pirast:
Yup. The gross speed is shown in the user interface of my WLAN AP, which is a Fritz box 7312 from avm
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
WLAN Speed optimization:

- Try disabling "WMM" / "QoS" (Wi-Fi Multimedia / Quality of Service).

- Try "n" only or mixed Mode "b,g,n"

- "n" needs "WPA2 AES CCMP" encryption for full Speed! (No WEP, no WPA1, no WPA2 TKIP)!

- Try fixed Channel, no auto channels. Use only channel 3-11!

- Try "2 Channel Mode / 300 Mbit/s Mode / 40Mhz Mode)

2x150 Mbit/s =300 Mbit/s --> 40MHZ

2x 75 Mbit/s =150 Mbit/s --> 20MHZ

it also depends on "HOW MANY ANTENNAS YOUR ROUTER HAS" -> http://en.wikipedia.org/wiki/IEEE_802.11n-2009

Info:

IEEE 802.11 2 Mbit/s max

IEEE 802.11a 54 Mbit/s max

IEEE 802.11b 11 Mbit/s max

IEEE 802.11g 54 Mbit/s max

IEEE 802.11h 54 Mbit/s max

great info man, I did the channel thing and it really improved my wi-fi speed, (it wasn't even reaching 1mb) in fact, I even thought of enabling the channel 14 to avoid any interference, but, I still can't get more than 5mb on my phone :/ (vs 12mb on my pc) do you get the same speed on your router as on your laptop/pc?
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
I think i also never managed to get the 150 Mbit/s Mode on my Ri. I have the bad feeling that the Ri is at least capable of the "n" Standard but

didn´t get the MIMO feature of 2 discret WLAN-Antennas or it can´t manage 40Mhz bandwidth...

I will test again if i´m home...

P.S. be sure to use "WPA2 AES" only! Not WPA1+WPA2 mixed mode and not "WPA2 TKIP"!

---------- Post added at 03:13 PM ---------- Previous post was at 02:56 PM ----------

Oh that´s bad...

i´ve just read that some Intel-WLAN-Chips don´t support 40Mhz Bandwidth on 2,4Ghz but on 5Ghz.

I don´t know if we got such an Intel-WLAN-Chip in our Razr i, but that could be the Problem...

Anybody here to test if a 5Ghz connection shows 150Mbits?
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
running iw list shows that even @5ghz it doesn't support 40mhz Bandwidth, I'm so piss off that my friend iphone managed to deliever the same speed as my desktop machine.
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
i´ve been looking for some chipset-spec´s of Ri Wifi-Chipset but did not find anything detailed...

Maybe its possible by modding some configuration-files to allow 40Mhz Bandwidht...
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
I just tested, set mode to "n" only, my razr can't connect, its like it tries, and then it fails and it goes like this foreverm and by looking at the iw manpage, when ti connects it looks like it connects in "legacy mode"

yeah me too, but didn't found anything, except for the above and this, maybe its a bug in my router that makes the phone fall in that legacy mode, dunno.
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
i have a little update:

- Razr i is indeed MIMO capable (11n standard), but can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver).

That means it realy can have up to 150Mbits in a 40Mhz Bandwidth network.

can only use one paralell data-stream (1T1R = 1 transmitter 1 receiver) with 20Mhz Channels = 75Mbits max.

BUT:

- The newer 11n standard not allows to manually select 40Mhz Bandwidth in a 2,4Ghz Network :(

(There are some older "N-Draft" router that allows manually selection of 40Mhz Bandwidth in a 2,4Ghz Network)

The newer 11n standard only allows 40Mhz in a 2,4Ghz Network in "Auto Channel Mode" together with 6 free Channels in a row.

In a 5Ghz network it is allowed to use 40Mhz manually because there are much more channels to use...

So on newer router with 2,4Ghz and 20Mhz Bandwidth network you will have max. 68Mbits brutto (= ca. 5 Megabyte/s netto).

Maybe you could get an older n-Draft router to test, or play with the 5Ghz setting?

Just check if your Router is able to set up 40Mhz Channels in a 2,4/5Ghz network...
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
well, my router allows me to use 40mhz in a 2,4Ghz network, but the problem remains, also it doesn't let me use the 5ghz band, still 5 m.bytes netto should be more than enough for my 10mbits internet connection, I guess I need to try on another router, or get more feedback from other users.
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
Can you try renaming your 5Ghz Network to an other name than the 2,4Ghz Network!?

I have something read about that this could be a problem...
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
it doesn't even have a 5ghz band lol, I'm going to try to measure the local speed, maybe there is an issue else where....

edit: nop, I get almost the same speed albeit a little faster (8/10mbits)
[RAZR i Q&A, Help & Troubleshooting] Lucki_X:
I have had halved speed if I have tried it on a special app for measuring connection speed, but I have the same speed as on my PC if I use browser and it tests on my razr I.
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
where do you test it? (don't tell me it feels equally fast)
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
If have made some very good Tests with a couple of diferent devices and i think i have found "the problem".

There is a detectable "power save" feature in the Ri Wifi-Chipset that holds the Ri to go over 65Mbits... :confused:

And also some good news: there is detectable feature of "STBC" that is a part of MIMO.

I will post details tomorrow... maybe there is realy a way to fix it somewhere... :)
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
It should be:

sudo iw dev wlan0 set power_save off

but for some odd reason my terminal emulator can't get root access :/
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
thats the same on me... 65Mbits in "n" mode with WPA2 AES CCMP. And about 18Mbits internet download (same as on PC).

But the Ri should do 150Mbits because of its STBC/MIMO feature...

---------- Post added at 12:31 AM ---------- Previous post was at 12:27 AM ----------

yes, you are on the right way! :good:

there must be some way to disable the power-save feature to get the full speed...

i will try to find some infos about that until tomorow
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
well iw wlan0 set power_save off now works, but the problem remains, dunno what else to do, I hope you get better luck.
[RAZR i Q&A, Help & Troubleshooting] patoberli:
Btw. don't disable WMM. I'm pretty sure to have read that it is required for 802.11n standard to operate at full speed.

Also the speedtest App or website doesn't really reflect the true speed. You would need to measure with a file download from a reliable fast server.
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
Disabling WMM was only for testing different settings. I noticed no difference in speed, but it is needed for priorisation of streams (VOIP etc).

You are right, speedtest.net App doesn't reflect the true speed of the WLAN connection. It was just to test if the phone got same internet-speed as the PC... For real testing you need a Gigabit-LAN to WLAN and a few big files to copy around...

Wifi Powermanagement is Kernel task. I dont know how to tweak Kernels. Maybe we can get some help of someone who as more experience in Kernel tweaking? Here is a Post about a tweaked Nexus 7 Kernel with "User configurable Wifi power management mode (PMFAST/PMMAX)". http://xdaforums.com/showthread.php?t=2168787

Sounds realy interessting... Did you know somebody could help us with that?

---------- Post added at 12:48 PM ---------- Previous post was at 12:22 PM ----------

here are some details from table "Data rates" (Wikipedia: IEEE 802.11n-2009):

Spatial---------------------Data rate (Mbit/s)

streams-----20 MHz channel-----------40 MHz channel

----------------800ns GI--400ns GI-------800ns GI 400ns GI

1--------------65.00--------72.20-----------135.00------150.00

2--------------130.00------144.40----------270.00------300.00

GI (=Guard interval) : "The standard symbol guard interval used in 802.11 OFDM is 0.8μs. To increase data rate, 802.11n added optional support for a 0.4μs guard interval. This provides an 11% increase in data rate."
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
here is an example of the S3:

S3 got 150Mbits... But only in 5Ghz Networks with 40Mhz Bandwidth...
[RAZR i Q&A, Help & Troubleshooting] 5m00v3:
Here are some good Informations of the restriction of 20/40MHz Channels in 2,4Ghz:

http://www.smallnetbuilder.com/wireless/wireless-features/31743-bye-bye-40-mhz-mode-in-24-ghz-part-1

An here is some Information of the first Medfield Phone "Lava Xolo X900" released in spring 2012:

http://www.anandtech.com/show/5770/lava-xolo-x900-review-the-first-intel-medfield-phone/9

"For WiFi and Bluetooth, the X900 uses a TI WiLink WL1271 series 6 combo chip which supplies 802.11b/g/n single spatial stream on 20 MHz channels with the short guard interval rate of 72 Mbps"

So if the Razr i got the same Wifi-chip there is the problem. If have also read that intel Wifi-chips in 2,4Ghz are locked by default to 20Mhz Channels, but that they could be set to 40Mhz... So maybe there is realy a chance in modding the Kernel i think...

But i dont see any hints of 40Mhz-Channel-Guard-Interval or higher Bitrates than 72Mbits.

I dont think anymore it´s possible to speed up the Wifi connection... :(:(
[RAZR i Q&A, Help & Troubleshooting] YaPeL:
thats the ARM version, although, the x86 is almost the same.

maybe doing this:

#define HW_RX_HIGHEST_RATE 150

#define WL12XX_HT_CAP { \
.cap = IEEE80211_HT_CAP_GRN_FLD | IEEE80211_HT_CAP_SGI_40 | \
(1 << IEEE80211_HT_CAP_RX_STBC_SHIFT), \
.ht_supported = true, \
.ampdu_factor = IEEE80211_HT_MAX_AMPDU_8K, \
.ampdu_density = IEEE80211_HT_MPDU_DENSITY_8, \
.mcs = { \
.rx_mask = { 0xff, 0, 0, 0, 0, 0, 0, 0, 0, 0, }, \
.rx_highest = cpu_to_le16(HW_RX_HIGHEST_RATE), \
.tx_params = IEEE80211_HT_MCS_TX_DEFINED, \
}, \
}

And adding CONFIG_WL12XX_HT to the config file (I dunno where or how exactly, there are a couple of files containing that string on the omar kernel) should compile (IEEE80211_HT_CAP_SGI_40 is defined) but I doubt is that easy.

Also, you are looking at the version 3.3 (is that for the kernel version?), latest one (3.4) doesn't even define the CONFIG_WL12XX_HT

Again, without the help of someone more experienced on this kind of stuff, its pretty hard... Maybe writting to the authors (the guys that appear at the top of that page) could highlight us better.

Btw. 72 Mbit/s brutto will netto to around 35 Mbit/s! So if you have a lower rate/speed it's more probably a server app issue and not the mobile phone.

There was a test-scenario i got only 5mbits with g or n. But i dont remember the cause of that (i think it was TKIP instead of CCMP)

-> will test again at home

[Nexus 7 Q&A, Help & Troubleshooting] vinicarus:
I'm trying to remove my car stereo and mount my nexus 7 (2013) in the dash. Certainly not a new idea. Making phone calls seems to always be a hurdle for these projects. Tablet Talk allows you to control a bluetooth headset (like a Parrot) for making and receiving calls, but it cannot control the call volume. No one seems to have a good solution other than use the Parrot volume controller or just go VoIP.

One option is to pump the Parrot's output into the mic on the tablet and then use Mic to Speakers, but then I lose Android's voice recognition, which is not acceptable.

Anyone know of a way to have 2 inputs so I can get the Parrot output into the tablet and still keep the mic available for Android?

[Moto G Q&A, Help & Troubleshooting] SkuzFoz:
The US version just has some extra frequency bands for T-Mobile. They mostly operate on a different band in the US than they do in other countries. If you're not using US T-Mobile, there's really no reason to buy the US version. The Global version will work a little more reliably for you.
[Moto G Q&A, Help & Troubleshooting] nlra:
The global version will likely work a *lot* more reliably for you if you're outside the United States. The U.S. version doesn't add extra frequencies, it trades those frequencies for other frequencies. So the U.S. version cannot work on certain frequencies that the global version can, and vice-versa. (The U.S. version cannot do HSPA on 900MHz while the global one can, and the U.S. version doesn't support networks that use 2100MHz for the downlink and 1900 for the uplink...its 2100MHz support is limited to AWS downlink.) This means that the U.S. version will, in a large percentage of countries, be limited to using EDGE networks. It really is too bad that Motorola couldn't manage to make a single model that covers all of these bands...

My impression is that there are very few carriers worldwide that operate on band 4/AWS-1. T-Mobile U.S. is probably the largest one, and even they are actually in the process of refarming their spectrum. My understanding is that they are turning down some 850MHz 2G transmitters, moving some HSPA+ over to that spectrum and some to 1900/2100 (band 1), and then re-using their AWS-1 spectrum for LTE. Once that happens, even the global version of the Moto G will work fine on T-Mobile. The global version already works on AT&T, and if you are in a metro area where T-Mobile has already completed the spectrum shuffle, the global version will work for you, too (and allow you to use your phone on HSPA networks if you ever travel outside of the country!). So for many people in the U.S., I would argue that the global version might actually make more sense, especially looking forward.
