[Q] Implement Undervolt in a Kernel? - Android Q&A, Help & Troubleshooting

Hi, I want to root and flash with the best available rom for ace 2x. I try to follow the instruction in ace 2 x root kit but I don't have the sd card. Can I do it without sd card? like using odin to install the CWM-Superuser_1.0.1.7.zip. Thanks. And keep up the good work.

The file for controlling frequencies / default voltages in most kernels is located at
Code:
/arch/arm/mach-msm/acpuclock-8960.c
Do be careful while adjusting these! Keep in mind that not all devices can undervolt the same amount before bringing these down to the extremes.

While I'm not the expert, I think any post with [MT65xx] in the beginning will apply to your phone. For example, this: http://forum.xda-developers.com/showthread.php?t=2160490
BTW, nice phone! Looks like the real S4, just that the S4 I've seen was black.

Thanks for your advise but am not that experienced in Rom cooking ,so it would be better if someone has the ROM ready cooked so i can try it in my phone.

Sorry in advance, I don't want to get your hopes up - I'm definitely NOT a developer! I had a question about your device though. I have near identical specs to yourself in my phone (GT I9502):
ALPS GT I9502
SYSTEM (Android 4.2.2)
Model: GT-I9502
Manufacturer: alps
Chipset: MT6572
Device: android_4x_wet_jb3
Product: android_4x_wet_jb3

Does any of the above look remotely familiar to your own device?
My phone is bricked, but research suggests that I might be able to build a new ROM based on the "system/" of a working device, using Android Kitchen. I'm told that entering the following code into the Terminal Emulator on a working device, creates a dump of the "system/" on the SD card, which can then be used to build the custom ROM in Android Kitchen:
Code:
tar -c system/* >> sdcard/system.tar
If you give this a go, and succeed in Android Kitchen, I'd be really grateful if you could let me know, and perhaps share the ROM? At the moment finding a copy of the stock ROM looks to be my only solution at this point!
TIA

Ok, not to worry. Unfortunately I can't give you the link to the website. The original advert said that it had an 8MP camera, however it only has 4.9MP! I challenged the seller on this, and it looks as though they have stopped advertising the phone. I bought it through Amazon and the seller was 'Active Tek' based in China. I would avoid using this seller as they clearly missold the phone to me.
hi could you help me with the s4 clone I've tried it to load an images which is not so successful but this is also happening to my regret my backup is gone great if you had what
same phone!

i have the same phone. but dont know how to root it. visit: samclone.blogspot.com
Hi, I have got exactly the same device as you have. I got the parcel yesterday; it had an app pre-installed called antutu, that antutu thingy says that the device has got arm v7 CPU named universal 5410, clocked at 1.7 gigs.
Ram of about 2 gigs and internal storage of 16 GB. However today I installed an app named CPU identifier that showed that its CPU was mt6572, mali400 GPU and to a heartbreaking surprise, only 512 mb of ram. Please tell me that this CPU identifier is crap and I have got a whole 2 gigs of ram. One more thing is that device is stunningly fast and efficient in handling big apps.
I also found some flaws; smart pause and smart scroll (eye sensor) only worked once or twice; GPS never worked; hand flip only works on one side. May be these issues can be resolved by installing a custom ROM.

running out of phone memory after installing custom rom

Sir,
i recently rooted my phone. After that i have install custom rom. And my problm is this that i had install custom rom one after another for 2 time. To see which one suits its better. But now i m seeing that i have only 25mb left in my galaxy y dous gt s-6102. Sir plzz help me i am in very panic situation dnt know how to deal with it. Plzzz help me ASAP.
Thanks in advance.
Mayur.
Help if I can
That sounds like a very frustrating situation! I have some experience flashing ROMS on different phones, but I am no expert. I am not familiar with that specific phone, but if its like other Samsung phones I am familiar with there is a detailed, listed procedure for flashing a ROM. Usually there is some type of system partition format or factory reset involved to remove files that may not be compatible with the new ROM. I suggest searching this forum for your specific model, then for a post with a step by step instruction to flash a ROM. It may be you missed a step. At the very least, you can try to reflash with confidence.

[Q] Attempting to overclock obscure tablet

I have a Proscan PLT9045K 9" rooted tablet.
The only thing I've really done to this tablet it root it and swap the internal sd (1gig) with external sd (32gb class 10)
I'm looking for anyone kind enough to help me overclock this tablet a bit so I can run games like GTA:SA with less lag. I don't have any custom roms or kernels installed and I can't install clockworkmod with Rom Manager because my wifi is a bit screwy.
Can someone please help me?
If you need any details on my specs then you can just download the pics (Can't post links yet because I'm too new of a user)
Also, if I'm not giving you enough information please just tell me what you need. Anything to help you help me.
Cant be done without a new kernel.

So it turns out it was a data/logs issue with log files getting way too big. My phone is rooted and after some searching, I still couldn't see the logs folder. I ended up downloading a program called LogEraser which did it, and can be set to erase logs on boot. Solved!

i believe there are some out there, but you do have to wipe the phone to do it. Something about loading up the appropriate PIT file... wasn't very noob friendly and organized enough for someone like me

[SM-T585 KERNEL] Any chance this exists or is being made?

Hello, first post here. So basically, I have a Samsung Galaxy Tab A 2016 rooted, and now I'm looking into overclocking it. Any chance there's a custom kernel for that? Because I can't find one anywhere. Any help is appreciated.
