[Q] rom maneger?

Hi Guys,
i have a quick question, i installed rom maneger too see and when i tryed to see what roms were available it asked me to install the cwm recovery.
question is:
is it save to install the recovery true rom maneger? have anybody done it on the et4g?
can we use rom maneger at all with our phone?
It has been highly suggested by many well known devs that you should NOT use this app.
The CWM it wants to install is designed for a phone with a recovery partition which our phone does not have.
You will most likely brick your phone and would be better off dropping it in a toilet.
Thanks for the reply guys, i appreciated.

Does a custom rom really improve battery life over stock rom?

I'm hearing some roms like Slimkat can really improve battery life (standby and in use).
I've been using stock since I got this tablet and now I'm wondering if I should try some customs roms.
Do they really improve battery life over stock? Or maybe just using a custom kernel like Franco with stock is enough? Or maybe a custom rom + custom kernel is the better combo for battery life?
Thanks!
yes and no....

For the Nexus 7 i wouldn't really worry about the Stock ROM draining your battery. There are apps like battery doctor or Greenify which can help you save your battery life, but these apps will require your tablet to be rooted.
The Neuxs 7 Stock ROM isn't a battery hog type of ROM so you will be fine sticking with the stock ROM. If you want to try out new ROM's, the Android Community has made great apps and programs for the Nexus 7. You can install TWRP recovery manager which is an advanced recovery manager and you can install MultiROM which will allow you to install Multiple ROMs onto your Nexus 7 without every touching or damaging your stock Nexus 7 ROM. You can test out new roms in MultiRom without damaging your tablet or affecting your stock ROM.
Now there are custom ROM's that are really great for battery life don't get me wrong. I have a SGS3 with CyanogenMod ROM installed and I have another SGS3 running stock Samsung ROM and the stock ROM is constantly using the majority of the phone's resources. I am constantly having to kill apps to drop the used resources from 80% to 55% usage. So on my SGS3 phone that runs the CyanogenMod ROM i am getting much better battery life than my stock SGS3 phone.
One great thing about a custom ROM is it gets rid of a lot of the bloatware that most people will never use that takes up a lot of resources on your Android device. However, you don't have to install a custom ROM to remove bloatware apps. If you root your Nexus tablet you can install Titanium Backup which can be used to freeze apps and remove stocks apps that couldn't be removed without root/titanium backup.
Again as far as your Nexus 7, you will be just fine sticking with your stock ROM. However, give MultiROM a try. If you root your tablet and install TWRP recovery manager (all can be done with the WuGFresh Nexus Root toolkit -> http://www.wugfresh.com/nrt/) then you can install MultiRom with the push of a button. Just go to the Google Play store and download -> "MultiROM Manager" and run the app and it will install MultiROM fo you.
After you have multirom installed you can try as many custom roms as you want...
Hope it helps...

random freeze in all custom roms with kernels and basebands

Hi everyone,
I have this issue with random freeze daily 3 or more. I use custom ROM and magiks open bootloader.
I read the problem could be the open bootloader.
Can I use custom ROM and magiks with a locked bootloader?
We have 2 of this phone and the other is untouched with the Chinese ROM and that never freeze.
I need custom ROM and magiks but these freezes makes me crazy.
I have tried ROMs basebands kernels. Really need some help how to avoid these random freeze
Any answer is highly appreciated!

Open Bootloader is not the problem, many users here including myself are using Custom ROMs with open bootloaders without any freezes
Yep, I thought so but wasn't sure.
Now on the last custom rom flash I wiped the data as well and so far had no freeze but it is only a couple of hours.
Maybe restoring apps with data via titanium backup could cause freezes but again no idea

Question about kernels

Which one should you use?
What are the benefits?
Security concerns?
Can I install a kernel without reflashing OS?
Used my T now for some days rooted with supersu and using xposed, but would like to tweak the performance and battery life some more.
Cheers.
Kernels tend to work differently depending on your individual setup. I recommend trying each one you like for a week so it can settle in. Flash in twrp and wipe only the caches. Your OS will be fine.
In terms of security I would use kernels that are frequently updated and maybe are always upstream synced. I would dirty flash the OS or the stock kernel at least before changing custom kernels as they tend to have unknown bugs when dirty flashing custom kernel over custom kernel.
The benefits are that you can choose whether to limit performance for more battery life or to go beast mode with full power but by sacrificing battery life. It simply gives you more advanced control over it.
Thanks for the replies!
Installed Blue_spark kernel and tweaked the clockspeed some. Works like a charm, I guess OTA updates are out of question?
Would agree mostly with the above. But I tried dirty flashing FreedomOS Rom once, and that was a bootloop. Dirty flashing with OnePlus isn't like HTC 10/11 Roms/Devs. They always work no issues when dirty flashing.
You could always flash the stock boot.img in TWRP, Select flash Image, select the boot.img, and the boot partition to flash. You will lose root though. So you need to install Magisk, have that handy as well. And, then try another Kernel.

To root or not to Root

Im running the latest V 10 build. It is generally ok but battery life and esp speed could be alil faster. Ive done the usual tricks like turning down animations to make it feel snappier but it still isn't quite there.
Is it worth rooting atm? Are there roms that are actually better than Stock?
Also unlocking the bootloader will wipe everything, is there a way to get around that? I'd like to keep my data/ root and make a backup...
Cheers.
There is no way round wiping your data when you unlock your bootloader, you need to wipe dater for twrp to be able to access the internal memory. I'm still on stock tho with a custom kernel and I'm happy but not sure if you would be. Also with the custom kernel I lose about 1% a hour on battery when not in use.
So you're rooted with a custom kernel? As I understand it's not possible to install the kernel without root...
Yes I use elemental 3.00 kernel, no you don't need to be rooted as you flash the custom kernel through twrp but you do need your bootloader unlocked and twrp.
