Hi

Im searching for a car charger for the nexus 4 that will charge the device even on navigation running...I now that the Motorola Rapid car charger was good with the galaxy nexus.I dont know if itS ok with the nexus 4 because on the LG charger it sayS 1.2A?I read that the Bracketron Universal Dual USB Car Adapte 2.1A will just work as AC charger if plugged in with a USB charging only cable...but i cant find those cable to order online here i Canada...and i dont wanna do it myself and modify a regular usb cable :D...Soo if someone can help me it would be much appreciated.
[Nexus 4 Accessories] neotekz:
You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.
[Nexus 4 Accessories] jutezak:
I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.

I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.

For some regulator disasters:

http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.

http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.

So that is why I went with a premium brand.
[Nexus 4 Accessories] neotekz:
that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...

Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.
[Nexus 4 Accessories] M3Rocket:
1. Get a bullet-type 2.1 amp USB charger:

http://www.amazon.com/iFlash-Lighter-Charger-Adapter-Output/dp/B008LM45I2/ref=pd_sbs_misc_7

2. Add a "charge only" USB cable:

http://www.amazon.com/Mediabridge-U...357979634&sr=1-11&keywords=usb+charging+cable

This combo charges a Nexus 7 (which requires even more current) with navigation on! :D
[Nexus 4 Accessories] aldenh:
Thanks so much for the link.So is this Trident limited charger same as the Powergen dual usb??I mean is the quality ok???this charger has the data pins shorted and comes with a regular micro usb cable?
[Nexus 4 Accessories] aldenh:
That looks ok,but I cant find a good quality usb charge only cable that ships to canada ::(
[Nexus 4 Accessories] aldenh:
I have a el cheapo usb charger from ebay and I used my usb cable that came with the phone...and when i pluged it in it switches from AC charge to USB ever couple of seconds back and forth...so I want to try something different.
[Nexus 4 Accessories] bfspider:
If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.

Monoprice has a 2.1A bullet charger for a bit cheaper:

[Nexus 4 Accessories] neotekz:
i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.

There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.
[Nexus 4 Accessories] aldenh:
Once again thank you so much.I found the Trident charger here with free shiping to USA and Canada :D and good reviews :D
[Nexus 4 Accessories] thesebastian:
I just bought a "Samsung Car Adapter" with this output: 5V 1A

Is this a good CAR adapter for Nexus 4?

The Nexus 4 "LG travel charger", has this Output: 5V 1.2A

I wan't to use this Samsung Car Adapter while using GPS on the Car or playing games on the Car without lowering the battery.
[Nexus 4 Accessories] Kazliux:
I have the same. Works perfect

Sent from my sexy Nexus 4
[Nexus 4 Accessories] Jaxidian:
FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.

The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.

If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).
[Nexus 4 Accessories] spile:
Why does a bog standard USB cable work in the car for me? Using a proper off-line sat nav my phone was fully charged
[Nexus 4 Accessories] aldenh:
So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.
[Nexus 4 Accessories] Jayrod1980:
The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.

Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.
[Nexus 4 Accessories] aldenh:
I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S

How did you try unlocking the bootloader?
[Android Software/Hacking General [Developers Only]] eejayyeahuuh:
after you type "fastboot oem unlock" look at your tab and use the buttons to select it. It gives you about 10 seconds until it reboots back to the bootloader

Oh and I can't get the sideload to kick in. I put in "CWM-SuperSU-v0.99.zip" but it doesn't do anything.

Im wondering if I can push it over using adb install bc adb sideload isn't working?

Thanks

everytime I do it .... it looks like it will work... then check root with rootchecker or susuperuser.... no luck.....

If the root did work... would app2sd work... or do I have to wait for a custom rom?
[Android Software/Hacking General [Developers Only]] expat1906:
Same result here!

Exactly the same results as the previous guys, every step appears successful, including sideload, but no SU after reboot. My Firmware has WW in name.

Only messages seen during sideload which imply errors are E: can't mount /cache/recovery/log etc etc.

Anyone any idea what may be wrong?
[Android Software/Hacking General [Developers Only]] justinnickovtime:
I figured it out!!! XD Use the new CWM provided by skellums http://xdaforums.com/attachment.php?attachmentid=1637836&d=1357974009

After the file downloads, move the CWM-SuperSU-v0.99.zip file to your external sd card. Go through the same steps in DjDoms tutorial, but replace fastboot boot recovery412-touch-new.img with fastboot boot recovery-cwm-a110-fromsource.img. When it boots into cwm, go to "install .zip from sd card". Navigate to CWM-SuperSU-v0.99.zip in your sd card. When prompted, select yes. Reboot after it finishes. I used Root Checker Basic to verify that I was rooted. You can get it for free in the Google Play store.

Acer Iconia A110 Root

I did all of this, boot loader is unlocked as when I go through the process again, it says it's already unlocked. I'm using an Acer Iconia A110 7" Tablet running 4.2.1. Basically it gets all the way to the end, and when you say "navigate to reboot, select yes at the prompt and the tablet will reboot", I do that, but there's no prompt yes or no, and any root checker i download and run still says I do not have root access.

Any working program to transfer apps on external sd

Hi people. I was so happy to finally root my Acer Iconia Tab a110, but the main purpose was to be able to transfer applications on my external microsd card because in todays games size matter.

Sadly I have tried about every app on the play store and nothing seems to work. The only app that I found that seems to have potentiel is this one http://xdaforums.com/showthread.php?t=1410262

Still I don't know wich files to transfer for a game to work. If I transfer only the data pack (ex. obb file) then when I reload the game it ask's me to dowload again because it does not find the path.

Does anybody know of a file transfer program that really works and is userfriendly. Maybe a program that you are already using with your rooted acer iconia tab a110?

Thank you very much!

If you get no mounting errors with this, other than the external SDcard, then the most likely solution is to boot into your tablet and format the microSD card from there, reboot and try again.

DjDom:

It's worth noting in your guide that this won't work on Windows 8 straight away. The unsigned drivers will not install, even though they appear to. If you try to manually install the inf, then Windows 8 will complain.

To install these drivers, you need to disabled driver sign checks for Windows 8 - this requires you to go through a recovery reboot. It would be best to link another guide, this one worked for me:

Any working program to transfer apps on external sd

Try Link2SD (in Google Play Store), its free and comes without the ads. I've been able to copy Zen Pinball over to an ext4 partition on my sd card. You need to give Link2SD root permissions and then reboot. Don't forget to set the correct partition format for your sd whilst in the app (it will ask you).

To copy an app over to your sd make sure that you use the "Create Link" option and select all the tick boxes. Don't click on "Move to SD card" as that will not copy to the external SD. I had some problems copying the /lib/ dir and was getting a mkdir error message...had to reboot a few times before it worked.

Suggest we all get downloading and see how well this works for other apps as well.

Got it to work, but stilll have a question.

Thanks for the little tutorial. i had installed link2sd beore and did not know what to do with it. I ran into some problems, but after a few hours I got link2sd to work quite fine.

It had error messages when I had formatted both partition of my microsd in FAT32, then what I did is to format the 2nd partition in EXT4 and since then it works when linking programs. Sometimes it deleted my programs has it froze when linking for some reason, but then I rebooted and it worked.

STILL I have an issue. I installed a big game like Dead T rigger wich has a seperate huge obb file in the android folder wich is NOT move when linking the program. Anybody got a solution for this?

It seems link2sd works perfectly for other games wich don't have seperate data packs.

I am so happy, thanks to all of you's who contribuated to this thread. Now my tablet is worth the while!:good:

Backing up prior to rooting

Hello,

Thanks to everyone who contributed to developing a root for the A110. I am very grateful and am anxious to proceed.

Before I do, I have a couple of questions:

1. Back up & wipe. I'd like to back up my score/progress from Angry Birds Space. AFAIK, there are still no Angry Bird back-up apps for Jelly Bean. However, Titanium Pro, which I have, states that w/Jelly Bean one can do a full back-up prior to root. Does Titanium automatically back up to SD? If not, is the Titanium back-up somehow "immune" to the wipe that occurs when rooting?

2. Preparing the SD card. When rooting my other devices, I just stuck the SD card in and it worked. No partitioning, etc. Reading the threads concerning A110 root, it appears that SD prep is important in order to move apps/files to the card. What steps/choices do I follow to optimally format/configure my SD card? I have 64-bit Win7.

Thx.
[Android Software/Hacking General [Developers Only]] blokenfeffer:
Whilst I don't have the exact directory for the data Angry Birds Space saves it should be under /data/data/ - if you find the correct directory, you should be able to back this up without root using adb. Steps are available for Angry Birds, so I would imagine it's as simple as finding the alternative folder and swapping out the steps for the correct location:

adb pull /data/data/com.rovio.angrybirds/files/highscores.lua C:\MyBackup\ab_highscores.lua

adb pull /data/data/com.rovio.angrybirds/files/settings.lua C:\MyBackup\ab_settings.lua

Prepping microSD should be easy. I'd advice fully formatting the card via windows as FAT 32 - when you get to the point of testing the card in CWM, you should be able to go to the "install zip from sd card" option. Here you can choose to pick a file from SD card and it'll either show the directory listing, say no files found or throw you an error. Everything is fine apart from an error. You can put a single file on the card and list via CWM to ensure it's working properly.

It's also worth mentioning that if you're not successful in backing up, but you decide to do it anyway - it may be possible to recover the data if it gets deleted:

http://xdaforums.com/showthread.php?t=1994705

I have had no need to test this on the A110 however.
[Android Software/Hacking General [Developers Only]] mlk43611:

Solved my problem for data and obb games files

Solved my problem for data and obb games files. These uses games files can be moved with the Gl to Sd (root) apk found on the playstore.

https://play.google.com/store/apps/details?id=com.slf.ListglApp

But you have to run them within the application. Tested it and it works! Remember to check mount Android and sdcard. :victory:

Now we can gain back to power of storage on our a110 tablet!

Have fun!
