found this excellent guide on the hassles of porting an OS to a new device...

and this

http://stackoverflow.com/questions/...droid-kernel-porting-from-one-device-to-other

So looks like a month, best case, with expert developers and a device well-known for being hackable. So to port ubuntu to a $40 device, I'm thinking three+ months, plenty of risk, and much pain.

[General Questions and Answers] technicaltitch:
I was wrong. Ubuntu Touch is based on the CyanogenMod kernel, which is widely ported.

From Canonical's FAQ on the bits of CyanogenMod used: "The kernel and a few low level drivers for network, video, audio and some other hardware features are taken, all the higher level parts have been taken out. On top of this the whole Ubuntu is started in an chroot environment." ( https://wiki.ubuntu.com/Touch/FAQ#How_is_Ubuntu_Touch_connected_to_Android.3F)

As a result it has already been ported to about 40 devices, and porting to a further 30 is work in progress, listed here: https://wiki.ubuntu.com/Touch/Devices

CyanogenMod officially supports 172 devices, and unofficially supports another 59.

Hey guys, I've got a question. Our situation with the whole N4 roms and kernel stuff sometimes working "But Dont Do It" but it works "but it doesn't" thing is confusing. So, we have JB, 4.1, all that. What's safe to flash? Like, one place says Now we can use N4 Kernel Sources, then the next line says "Dont flash n4 kernel or face perma brick". All I really want to know short term is Can I flash Paranoid Android from the N4, and long term, whats safe to flash? Thanks guys
[AT&T LG Optimus G] xxgmon3yxx:
If you are converted then you can flash PA on your phone.

I know its a bit confusing when you have people say all kinds of stuff about the conversion but let me put it to you in a way a lot of people can relate. Doing the conversion is like when my mom used to tell me not to have girls spend the night, but I did it anyway because it was awesome.

So basically is up to you... and as you can see they tell you not to convert because the chance of a brick, and then if you do not convert you will still be a risk of a brick for flashing other stuff. You paid for the phone with your own money and you happen to live in a free country so you can pretty much do what ever you want with the phone that you paid for!
[AT&T LG Optimus G] gunnyman:
Here's what you need to remember. On non converted phones mako aka nexus 4 kernels are compatible but can't just be flashed from the nexus 4 forums because on a nexus 4 the partition map is different and the installer will put the kernel where it expects to find the boot img on a Nexus 4. Our boot partition is not in the same location
[AT&T LG Optimus G] ripin150:
Awesome analogy, I'll do the conversion when KLP drops, im stoked.

Ok, that makes sense. So, The PA build from N4 probably has their kernel built in, and I should wait till someone brings it over here. Thanks guys, I appreciate it.
[AT&T LG Optimus G] gunnyman:
On the Convert/don't convert issue I agree with what else has been said in this thread. It's your phone, you own it, you can decide whether or not you want to risk something going horribly wrong ™.

I converted my phone and ran N4 stock 4.2.2 for a while. everything worked as expected.

Currently I'm on stock Jellybean, trying to decide if I should stick with it or install one of the AOSP based ROMS.

I like the stock LG camera better for some reason.
[AT&T LG Optimus G] nygfan760:
Yeah whatever you do, if you do not convert, stick to ROMs posted in the OG forums.

I followed these steps

http://xdaforums.com/showthread.php?t=2046439

I downloaded the SuperSU_bootable_FIX.zip file, unzipped it, and took the three folders that where in there and copied them into my SD card on my phone.

I ran ODIN3.

and PDA the following file VRALEC Bootchain to allow custom recovery [this went fine]

after restarting my system and going into ODIN mode again, I used BOOTLOADER with the following recover: ClockworkMod Touch Recovery 6.0.2.3

After it finished, I unplugged my phone, turned it off,, and took out my battery, restarted my phone into recovery mode.

Once there I clicked on Reboot system and when it asked me if I wanted to disable Disable recovery flash, i clicked YES

the system restarted. and when the phone started, it shows the Samsung logo with a "unlocked" icon at the bottom of it.

Here is where the issues there:

When I try to run SuperSU, I still get "there is no su binary installed and supersu cannot install it" -- Is it possible I did not place the files in the right place? Does it matter where on the SD card I put the files? Or is the issue something else?

I inserted my new Tmobile SIM card, and I still "Non-Verizon SIM" error -- I think this is related to the fact that my phone is not rooted yet? Or did the unlock fail as well? Is there something I need to do to allow for the Tmobile SIM card, or is it because I failed somewhere along the way, following those instructions?

I would really appreciate any help.
[Verizon Samsung Galaxy S III] SlimSnoopOS:
Why did you unzip the SuperSU_Bootloader_FIXED zip? That is not in the directions, anywhere. You simply just flash the zip in recovery.

Edit: I'm guessing you're new to rooting. While in custom recoveries (TWRP or CWM), you flash .zip files. While in Odin (for Samsung devices only), you flash .tar or .tar.md5 files.

THANK YOU SO MUCH! That part was not clear to me at all, I did not understand it, I guess I am as stupid as they come.

Kies and all latest version drivers has installed but when i try to restart my pc with Galaxy S3 is connected to my pc via usb, its barely restarts the pc. Both shutting down and opening getting slower if its connected. when i plug out the phone, computer opens normally. I have tried to reinstall the Windows 8 but same issue happens.

Its a question should be in Q&A.

Answer its your PC USB and settings not the phone probably BIOS as well .

Simple solution unplug the phone .

[Galaxy S III General] spamtrash:
Of course pls follow the above advice and ask mods for moving it.

secondly, I presume that any (relatively) slow and (relatively) huge storage would slow down the Windows.

Reason for it is obvious, it first tries to check on Windows Update if newer drivers are available, and then scans and indexes all connected at boot drives, two belonging to the phone including.

Last but not least: why are you booting PC with phone connected???:eek:

2. How can I fix this and get my performance back?!?!?!

Some got this problem. try Cold boot first, if that dont solve it back up everything and perform a factory reset and try reflashing the ROM.

[Galaxy S III Q&A, Help & Troubleshooting] debianguru:
Hi everyone,

Recently my Samsung Galaxy S3 GT-I9300 has started playing up.

When I power my phone on it display grey battery logo and keeps restarting itself in a loop.

I have two batteries and I use external charger to charge them up so I know its not a battery issue.

Not long ago my phone started going into Odin download mode often and I used to just Press Volume down + Home key + Power to get it to reboot out of Odin mode.

Sometimes it just boots as normal and I am able to use my phone.

In past my phone was rooted and I already tried flashing ROM few times to get it work. I have even performed factory reset few times but the issue seems to not go away.

Could anyone offer me any further advice?

The only way I can get phone working is if I always make sure its fully charged and never switched off which is not really a solution.

Thank you.

Hi,

I bought a month ago my AT&T Galaxy S II Skyrocket unlocked to use with TELCEL in Mexico.

I never used the tethering, never need to, until yesterday and it's not working. I got this message

"Mobile data is not available or invalid SIM"​

Is there any way to correct this, or the SIM from TELCEL is not compatible for this function with the SGSII SkyRocket.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] spitfire2425:
Is it rooted? If so download titanium backup and uninstall tethering provisioner and install power toggles. Then set up power toggles with the wifi tether button on there then try to tether like that. If that doesn't work then you should try it on a custom rom to see what it does.

Hi i was wondering, i now have rooted and now i want to add the statusbar mod, but they often say make a full backup in case anything goes wrong.

Do they mean like the backup you make with custom recovery like cwm or xzrecovery, or just the phones backup and restore or like titanium backup? As i want to be able to go back to the exact same state the phone is in at that moment but without the mod.

[Sprint HTC EVO 4G LTE] Va1ha1a:
Hi. My phone was bootlooping this morning, I decided to wipe data (I had a backup of /data) reflash, and carry on. However, I accidently confused the factory reset option in TWRP with the one in the bootloader, and clicked the bootloader one. This wiped my internal sd card. I tried to use things like Undelete from play, but it only works on the external sd. I've been trying to follow this guide (http://xdaforums.com/showthread.php?t=1994705) to regain my data, but I don't know what the name of the /data partition is (for example, for the galnex, it's mmcblk0p12). Does anyone know A. what the name of the partition is for the evo, or B. an easier/different way to recover my files? Thanks in advance for any assitance.
[Sprint HTC EVO 4G LTE] roids87:
/data is mmcblk0p37 according to steelh over in this thread
[Sprint HTC EVO 4G LTE] Va1ha1a:
awesome. however, is /data the same as internal sd card?
[Sprint HTC EVO 4G LTE] roids87:
I am not sure. You could try and use the Mount Point Swapper and see if undelete will work then. I'm just tossing out some ideas. I've never actually tried to recover anything.
[Sprint HTC EVO 4G LTE] Va1ha1a:
I'm gonna necrobump that first thread you linked to and see if anyone knows. I'll also try mount point swapper.

Edit: I've tried everything. mount point swapper caused bootloops, the guide i mentioned earlier created .raw files with nothing inside, etc. The upside is that I didn't have my roms, photos, or music on the internal. I can't remember. What else does android normally store there?
[Sprint HTC EVO 4G LTE] roids87:
Usually not much, random app data, downloads, photos, music(depending on settings). You may get a warning in Titanium Backup(if you use it) about a different android id, you can restore your old id, or keep your new one. I have yet to see any issues. I've restored old id's and kept new is's without issues.

Hello all,

This is my first thread for XDA. I made this tutorial for get any Sony XPERIA U official ROM in the world.

Before you need:

ROOTED XPERIA U

Root explorer or Solid Explorer

PC Companion

first open the build.prop (system/build.prop) using root explorer. and edit these 3 lines to your desired firmware customization number

(Customization numbers @ 2nd post)

ro.product.name=ST25i_XXXX-XXXX

ro.build.fingerprint=SEMC/ST25i_XXXX-XXXX/ST25i:4.0.4/6.1.1.B.1.10/9bt3zw:user/release-keys

ro.semc.version.cust=XXXX-XXXX

(XXXX-XXXX = you must enter customization number you want in this field)

Please use only the first customization number of this list.(Highlited ones on this attachment)

View attachment 1880911

and save it and reboot.

Now connect phone to the computer and repair the phone(re-install software) using PC Companion (not SUS)

then it will download new firmware before you chose. after it will say to turn off your phone and connect with flashmode. dont do it.(Because it won't work)

View attachment 1880912

Close the PC Companion software to cancel update.

Then go to this location of your computer:

"C:\ProgramData\Sony Ericsson\Update Engine\db\13740270\blob_fs"

(you can directly go to this link by pasting your address bar)

after you can see 3 larger files name like this

FILE_XXXXXXXXX = ~63KB

FILE_XXXXXXXXX = ~400MB

FILE_XXXXXXXXX = ~14MB

copy this 3 files to another folder and create ftf file.

Click the link below if you don't know how to create ftf file

and flash it using Flashtool and enjoy :highfive:​
