[Nexus 7 General] bftb0:
You mean VirtualBox? The source (system.img) file can be on the host OS disk, so long as you set up a shared folder from the host and then mount it in the guest. A couple of recent distros have VirtualBox support already "baked in" (e.g. Ubuntu, Debian, etc), so fooling with Guest Additions may not be required. You still will need to mount it though (google for "mount vboxsf").

Or were you trying to do it by just booting a "live CD" distro inside a VM? In that case, the /tmp or other (fuse-) writeable filesystems use RAM to hold write data and so are limited in size by how much RAM you can give the VM); instead you can just create a second "scratch" disk for the guest VM, and attach it to the VM before booting - it should show up as /dev/hdb or /dev/sdb. This doesn't require any VirtualBox guest additions, and a few distros even will allow you format that storage (basically, mke2fs) and mount it right from the desktop GUI.

That gives you plenty of writeable disk space in the VM, mounted in a native (extN) filesystem.

The last hurdle to clear (after the simg2img and loopback mount stuff) is getting the big output file *back* to Windows. A USB key formatted as NTFS will work in principle, but the USB passthrough in VirtualBox is dog slow (like USB-1), so that will take forever with a multi-GB file. A better approach here is to get the VirtualBox shared folder thing working in the guest; that will operate at > 80% of the "native" speed.

Hi,pls,after saving the file named system.ext4,how can we make it flashable ,or should it be renamed to .IMG format?

[Nexus 7 General] beegee:
Just open ext4unpacker.exe in your windows, then pull out system.img on your desktop

Choose file(system.img) from desktop in your ext4unpacker, wait for it to load. Then save it

META INF Folder?

Hey!

This was a great tutorial. :D :D

Everything worked fine for me, but can you tell me how do I get the META INF folder via this tool? :crying: Several other OPs redirected me to this thread, telling me to follow this guide. Is there anything I am missing? :eek: :confused:
[Nexus 7 General] beegee:
If you want to open META-INF/updater-script you can do it with NotePad..
[Nexus 7 General] acdroid:
I think you got me wrong.

My bad I didn't explain well.

When I extract, there is NO META-INF folder PRESENT! As in there's nothing. That's why, almost all my ports fail because figuring out the exact updater script for my phone is tough task, given no one has made anything for it.

Sorry, if I am sounding like a noob.

[Nexus 7 General] washichi:
You need Linux or cygwin to do that, Linux is easy: mount system. Img edit the files in the mounted folder, then unmount

If you don't want to use Linux I'd recommend that you delete the apk on your phone with a root explorer, then extract system.img with adb from your phone

[LG Optimus G Pro] idle0095:
Yes in rooted. Root Explorer. Titaniam back up. That's it for rooted apps. It's were ever.
[LG Optimus G Pro] Jammol:
Hmm, I've seen people back in the infuse threads have issues similar to these just because TB is installed. I have not personally experienced this issue.

Question...

Have you disabled any apps?
[LG Optimus G Pro] idle0095:
Yes all of the att bloatware. I removed some with root Explorer as well.
[LG Optimus G Pro] Jammol:
Did you just disable them or removed them completely? I'm wondering if there might have been something crucial that was removed. Wish we had a way to return to stock.
[LG Optimus G Pro] idle0095:
I only removed like 3 and the rest I froze or disabled.
[LG Optimus G Pro] Jammol:
Try returning your phone to stock as much as possible by undoing what you did. Even do a factory reset and use the phone without changing anything.
[LG Optimus G Pro] gage0727:
I have the same prob but I'm not rooted or any thing. at&t support supposed to call me tomorrow to try and fix it.

[LG Optimus G Pro] idle0095:
The worse thing is it still shows I'm in 4g or wifi but data stops working. Thats what makes it suck. At least if it didnt have the icons I could tell faster and do a quick toggle of airplane mode.

Swap that bad boy out then.

Yeah I definitely suggest swapping it too. Hopefully mine doesn't have any these issues.

i have 4 full bars of lte where i live. my htc one got maybe 1 or 2 bars. lg radios are kick ass.
[LG Optimus G Pro] gage0727:
k an update i ended up returning my phone and getting the Samsung s4. reason being i found out the lg dose not have a very good radio for rural areas. i found that it only has like two freq. for 3g and 2 for 2g. maybe with a rooted phone you can change out the radio from another phone or something. But an un-rooted phone it sucks. I really liked the phone too because nice big screeen and every thing.

Oh and the s4 blew the lg out of the water as far as signal and everything. I had an htc inspire before and had to mod my antenna in order to make phone calls from my basement. i was able to do the same with the s4 with out doing any thing too it.

[One (M7) Q&A, Help & Troubleshooting] coisman:
Hey guys, I just bought my One a couple weeks ago and I'm loving it so far. However, I'm having an issue with the USB charging speed.

I know USB charging speed is slower than wall charging speeds, but the speeds I have been getting are ridiculous. To charge my phone from 0-100 takes about 9 hours over USB when the phone is in sleep mode and not being used. Can anyone else tell me if they're getting the same kind of extremely slow USB charging speeds? Is this normal for the phone? I've been thinking about replacing it and seeing how the next one fares.

[One (M7) Q&A, Help & Troubleshooting] Bladerunner1825us:
Some Kernels have an option for fast charge which is supposed to help with it but certain usb ports only put out a certain amount of power. Also I know a problem with the OG note was with fast charge enabled a few charging ports burnt out (mine included). It was easy to replace them on that phone but this one will be more difficult if it does the same thing.
[One (M7) Q&A, Help & Troubleshooting] Bart1981:
The problem is that the phone sees the difference between an AC charger and a usb charger. With an AC charger it can charge with a maximum around 850mA while with an USB charger it charges with an maximum of 500mA.

There properbly is a trick how to make the phone think it's on AC charger, while it's actually on an USB charger, and therefore charge with a higher current, but I haven't found out how yet.
[One (M7) Q&A, Help & Troubleshooting] ArmedandDangerous:
Depends on the current battery level of the phone. Anything above 83%(somewhere around there), even on AC charger it will slow down to 500mAh at most.
[Galaxy Note II Q&A, Help & Troubleshooting] Sarmate:
Hello everybody,

I have the following problem appearing recently:

Whenever I connect a USB stick through OTG cable to my Galaxy Note II I always receive the message “USB Storage damaged. It may need reformatting” in the status bar, no matter which stick or other mass storage device I'm using. On my PC, the files are perfectly visible.

I didn't tamper nor change anything on my phone, it's been running the original Samsung ROM, rooted but otherwise unchanged, for the last six months.

Could any of you help? I explored several threads with reference to the same error message on other Android devices here and in other Android forums but none of them matched this problem.

Thanks in advance!

Hi,

Have you tried smaller sized USB sticks?

Because my 1 terabyte SeaGate hard drive works but turns off because it needs more power.

Yes, I tried with a 1GB and a 4GB sticks that worked quite well on OTG last week.

Both these sticks still work well on my PC.
[Galaxy Note II Q&A, Help & Troubleshooting] Simone:
Is USB Debugging ticked on settings?
[Galaxy Note II Q&A, Help & Troubleshooting] Sarmate:
It wasn't.

I did tick it but it doesn't change anything in the behaviour.

(BTW, thank you for taking the trouble to help me!)
[Galaxy Note II Q&A, Help & Troubleshooting] Simone:
No problem helping :highfive:

Well, I had no problems with USB OTG yet (except the 1 tb)

I suggest you factory reset or change the OTG cable.

I tried the cable as well...

Factory reset is a bit radical.

Does anyone else have an idea?

The problem is caused by kernel and USB drivers. Depends what kind of ROM is installed on your phone.

Some of the ROMs dont recognize big variety of card readers. Now I am using some cheap china phone,

so i had hard time to find the correct SD card reader.

Before, I was using Paranoid Android on Nexus 7, I didnt have problem with mounting any size of card, any kind of card reader.

Try different card readers , play around, you will fing the way.

[Galaxy S 4 Q&A, Help & Troubleshooting] rover.prince:
Hi folks,

I just bought my S4 i9500 a couple of days ago. since the box opening I am facing the issue my Sim card shows the signals and then loose them, and this keeps on doing it after numerous restarts and battery pulling ultimately my phone connects to the network. It's a factory unlocked S4 bought form official store. I have tried almost 5 other sim cards as well only one has been able to connect without any issue, the rest have same problem. Phone recognized the sim, but when u try to make a call or sent a text msg signals drops.

I gotta know if any other fellow has faced such issue. As I have also concluded one thing, if my phone's internal temperature goes beyond 45c then all the sims are recognized by it, but as soon as I go down 40c sim cards just connect and disconnect.

I need your opinion, what might be the problem and is there any other fellow who has faced this issue.
[Galaxy S 4 Q&A, Help & Troubleshooting] cmd512:
I am seeing the exact same issue on my i9500, the signal just goes to null out of nowhere, and comes back a few seconds later. It's happened on both my US carrier (AT&T) as well as the Taiwan carrier I'm currently using (Chunghwa), so it's NOT carrier specific.

As a comparison, I used the exact same SIMs in my i9300 and never saw such issues. This is NOT good...
[Galaxy S 4 Q&A, Help & Troubleshooting] rover.prince:
So far what I have concluded that, if the temperature of my phone goes above 45C then this signal problem seems to be gone, but as son as the temperature goes below 40C signals start to drop. Well I would recommend you to try to raise phone temperature by playing some games or performing antutu benchmark or use it on wifi etc to increase it's temperature and then see what's the outcome.

[Windows Mobile Development and Hacking General] wesley96:
I was attempting to use dumprom on a PDA phone other than XDA... I extracted the memory address from 0x80000000 to 0x81FFFFFF using pmemdump, and ran it through dumprom. As it turns out only the bootloader and a small part of the kernel got extracted. Nothing of the OS or the application files came out. As it turns out, looking at the dumped file, the 'good part' is missing and seems to be located elsewhere in the memory.

But then I have a rom image that can be used to flash the device, so I tried to use the image with dumprom, but that gave me an error, obviously, as the image is not laid out like how it's mapped out in the memory.

So how should I go about in extracting the files? For example, what do I have to do to modify the rom image to work with dumprom? I'll upload the rom image in question or the memory dump if need be.
[Windows Mobile Development and Hacking General] mamaich:
To dump ROM of any PocketPC, you should extract first 32 Mb of physical memory starting from 0 address. They contain bootloader and ROM image at least on PXA25x, 26x and 27x CPUs. For example you may use my program: http://mamaich.kasone.com/imate/ROMDump.rar

it comes with source code and dumps 64Mb of ROM to any directory on SD card. Later you can extract files from this dump with "dumprom.exe dump.bin -4 -d C:\dump"

I've tested this method on several devices and it worked. If device contains 32mb ROM, the second half of a dump would be identical to the first 32 mb.

The BIN/NBF files used to flash are sometimes stored in a format with unnecessary parts removed. Such files normally start with "B000FF" signature and their format is explained in PlatformBuilder documentation. You may try to write a program that would convert them to a "normal" dump that dumprom understands.
[Windows Mobile Development and Hacking General] wesley96:
Unfortunately, that didn't go well. The CPU is PXA255 and the OS is WM2003, but whatever ROMDump pulled out, it wasn't of any relevance. The attached file is what it put out. It's 64MB, but as you can see from the size of the compressed result, there's not much useful information in it. It's just a repetitive garbage data that goes on for the whole 64MB. Maybe the program was accessing the wrong area? To be sure, I ran the file through dumprom, and the program hanged. This isn't even as good as pmemdump, sadly. What seems to be the problem?
[Windows Mobile Development and Hacking General] mamaich:
Probably the problem is in wrong addresses to dump. You should modify my RomDump code so that it would check all 4Gb of adress space in 32-mb blocks to find a block that looks like a ROM start. Rom starts with someting like:

0000000000: FE 03 00 EA 00 00 00 00 │ 00 00 00 00 00 00 00 00  ъ
0000000010: FE 03 00 EA 00 00 00 00 │ 00 00 00 00 00 00 00 00  ъ
0000000020: 00 00 00 00 00 00 00 00 │ 00 00 00 00 00 00 00 00
0000000030: 00 00 00 00 00 00 00 00 │ 00 00 00 00 00 00 00 00
0000000040: 45 43 45 43 4C 4B 12 84 │ 00 00 00 00 00 00 00 00 ECECLKД
0000000050: 00 00 00 00 00 00 00 00 │ 00 00 00 00 00 00 00 00

I.e. XX XX XX EA bytes (it is a BL command opcode) followed with garbage (may be 00, may be FFs, may be other XX XX XX EA bytes), and "ECEC" string from offset 0x40 from the ROM start. "ECEC" is present at this offset in my device and several other. But this may be not in yours.
[Windows Mobile Development and Hacking General] gwu000:
I met this problem also. In my case, the BIN code of the ROM file that I ROMDumped from my device is looked like this

and the result of "dumprom.exe dump.bin -4 -d d:\111" is shown as following.

How can I solve this problem?

Thanks a lot.
