[Android Software/Hacking General [Developers Only]] [DarkGUNMAN]:
To answer any further questions i receive about how to alter the resources of Opera Mini, I'd better explain how it works and what you can do.

Opera Mini does not contain the skin and layout in the apk file itself, but downloads them directly from opera during the first start of the program.

This was a relatively simple mod using EasyApkDisassembler, changing lines in operamini.apk\assets\resources, resources-en and resources-en-gb.

I copied the lines for qvga and hvga into the vga and svga lines, this forces operamini to download the skin and resources required for a device with a smaller resolution, therefore the skin etc are smaller.

Aside from that i changed the install path of the app in AndroidManifest.xml, the name of the app in \res\values\strings.xml, and replaced the icons in \res.
[Android Software/Hacking General [Developers Only]] komwarior:
opera

that was cool man.

May i ask, is it possible to change the color of the skin when it is downloaded? Where is the downloaded skin located? Thanks man
[Android Software/Hacking General [Developers Only]] chrissoriano:
why I cannot install your opera mini?
[Android Software/Hacking General [Developers Only]] Sujan Baruah:
Rotation crash

Opera mini 7.5 mod of yours crash on changing screen orientation. Either I keep my device forced to stay in one particular orientation or kill the app from the task switcher- change orientation- re open opera (so that it loads the pages from the cache). That's the only workaround to the crash. Changing orientation while the app is running leads to full reset of cache (hence the next time I open opera, the pages already loaded before won't show up from the cache). So killing app from outside and changing orientation is absolutely necessary. (this workaround only works which the pages have loaded fully... Not partially). So it's necessary to wait for all the tabs to load in order to change orientation using my way.

Please fix this as now I can't go back to normal looking opera. Your mod looks best and is most user friendly. My phone has 960x540 resolution. 4 inch size. Using the hvga version.

[Nexus 4 Q&A, Help & Troubleshooting] Lanx95:
Hey there, I was just wondering why game on Nexus 4 is more lagging compeer with Galaxy S3 (NFS MW12, GTA Vice City) and have less effects again compeer with G3 (Modern Combat 4)?? :fingers-crossed:
[Nexus 4 Q&A, Help & Troubleshooting] spitefulcheerio:
*compare

And it might be an issue with your phone. I experience zero lag while gaming. Also, search a term called "thermal throttling"
[Nexus 4 Q&A, Help & Troubleshooting] Flynny75:
It may have less effects as developers are still finding it difficult to get their hands on one. Once they do, I expect them to test it with full effects and update as appropriate
[Nexus 4 Q&A, Help & Troubleshooting] AppReviewBros:
I hope that's true as after watching a comparison between the Nexus 4 and Nexus 7 I am sure Nexus 4 can handle the graphics.

[Xoom Q&A, Help & Troubleshooting] gtludwig:
Hi all,

I just got me my first Android tablet. I chose the MZ607 and am very happy about this purchase.

I know it has some very nice hardware and I know Motorola issued an ICS ROM to it.

Since I got it for home use, I'd like to use the multi user feature of the latest ROM.

Question is: can my tablet run Jelly Bean 4.2?
[Xoom Q&A, Help & Troubleshooting] Chaosgod27:
Yes it can run 4.2, but first that all depends on if there is a recovery for the XOOM 2 ME version. I know that runandhide released a recovery for the XOOM 2, but don't know about XOOM 2 ME.

Also if any developers would make a ROM for the XOOM 2. Oh usually devs hate it when you ask for ETAs, so don't bother asking. It be ready when its ready.

I used this:

http://androidforums.com/gome-flytouch-3/352291-help-partition-sd-card.html

method to try to create an ext2/ext3 partition, the problem is it simply doesn't appear to work - actually the phone asks me to reformat my SD card. Anyway I'm really not sure what's happened here, I rooted my phone/flashed the previous ROM so long ago that any knowledge has basically gone out of the window, so whatever info. you need, do ask,

Thanks
[Desire Q&A, Help & Troubleshooting] eddiehk6:
gparted or 4ext recovery are the best ways to partition sd card. don't know why you're looking in other device forums. searching around here you'll find that you should not use minitool...

backup your sd card, then look here (step 5), stick with guides that are written for your device
[Nexus 4 Q&A, Help & Troubleshooting] ericvolp12:
I just dropped my Nexus not 10 minutes ago, from about 3 feet up or at pocket level it didn't successfully slide into my pocket and fell. There is a crack on the top right hand corner of the screen that spreads across to about the middle of the left side. My touch capabilities are not working whatsoever, but the volume and power buttons work. I was wondering if I could fix this somehow, or maybe re-lock my bootloader to apply for a warranty. This is a warning to all Nexus users and my Question is has anyone else experienced this where a single small drop cracks the screen half way and renders the entire phone useless?
[Nexus 4 Q&A, Help & Troubleshooting] germanj:
Unfortunately, that means the digitizer is toast and you will only be able to get it fixed through a hardware replacement. Really the size of the crack doesn't matter in these cases. Warranty doesn't cover accidental damage either, but rather manufacturing defects. The best course of action is to send it to LG and have them replace the broken hardware, I believe they charge $200.
[Nexus 4 Q&A, Help & Troubleshooting] spitefulcheerio:
Lol a warning to all nexus users? How about a warning to all smartphone users?

Re-lock your bootloader and call google
[LG Nitro HD] pcguru000:
Happens on every rom (currently on a cm10 nightly) ... phone is stable in just about every other way, but 1/50 (guessing) the unlock just goes sour.

It's as if the screen doesn't come on....

I tried raising my min cpu freq while sleeping- even at 512mhz it still did this occasionally.

Any thoughts?
[LG Nitro HD] nate1975:
I've had this problem for quite some time as well, and I've read about it in the forums before. I believe that and the reboot in the camera app (try unlocking) are the two biggest issues right now. From what I've read in the android development forums these are likely kernel issues that won't be solved easily.
[LG Nitro HD] lordcheeto03:
CM10 has been notorious for this since day one. I haven't used a CM10 nightly in about 2 months, but I had quite a few BSOD's in ParanoidAndroid. I've been using tdmcode's AOKP41 for the past few days and so far I haven't had a BSOD, but from what I read in his thread in the development section I'm lucky.

One thing that makes it "less" of a hassle is that you can hold the power button until it reboots (around 10 seconds, maybe 15 or so) instead of pulling the battery.

Checking MD5 sums...

Erasing boot before restore...

Restoring boot image...

Restoring system...

Error while restoring /system!

I did nothing but boot into recovery and this is all that happens when trying to recover my cwm backups. The version of CWM should not have changed and I've flashed these files before. I accidentally started another backup and shut the phone off while it was plugged in through usb (debugging might have been enabled but I don't use adb commands or have a shell).

I can restore my rom but I want to restore my backup.

How can I know the version of the backups and see if they are different from the cwm recovery version? Also in the past I have flashed and backup through rom manager, but would my rom manager boot into cwm recovery load a different cwm recovery (it shouldn't)?

I also tried this...reload the rom but restore each partition except for system, but it fails on data too then.

At a loss here. I love my backup. I was just a system camera apk away from perfection

Please help

Solution: 5 hours of playing around and the solution is that you need to make sure the cwm version is always the same...through rom manager.
