[Q] Flashing kernals and roms questions

I have a kernel that i found that i want to flash. When you flash a kernel, does it replace a flashed ROM or do they combine?
Also, when you flash anything (ROM or kernel) does it replace the stock ROM or does it take a spot next to it? Can you make several spots so there can be more than one ROM? What is wiping out a ROM? If you leave a ROM, can you save your setting so when you go back you don't have to start over again? Can you back up contacts,messages, and apps from stock ROM and extract the data to the new ROM?
I AM CONFUSED

1. No, they "combine"
2. It replaces it when you flash
3. Yes, but its more complicated than just flashing multiple roms. There is an app but it doesn't support Sensation.
4. Wiping a ROM is just that, wiping your phone of the ROM along with all your app,data and anything else on the phone(SD card not effected).
5. Umm. I don't understand your question completely but yes flashing a new ROM over an old ROM will preserve your data but you can flash a different rom and expect it to work. For example ARHD-->ARHD(updated) is OK but ARHD --> Insertcoin wont work.
6. Yes, its called titanium backup. Look it up.

thanks. after reading this, I stumbled on radios. what are radios?

Radio is what gives your phone signal. which version works best for you will depend on your location and carrier so you will just have to experiment. its generally advised that you flash the latest recommended version stated on the rom your using

The only thing I'd add is that for:
o If you leave a ROM, can you save your setting so when you go back you don't have to start over again?
You can do a Nandroid backup from CWM recovery, it takes a snapshot of the ROM, Kernel, Data,.. You can then play with other ROMs. Then at a later date restore the Nandroid backup from CWM and you're back at the earlier ROM.
It's extremely important that when you play with ROMs you backup a working version. It saves a lot of swearing when you lose a nice working system unintentionally. It's happened a couple of times to me and it's a bugger.

[Q] Question about updating ROMs

Hello,
I recently installed custom Jellywiz rom on my Verizon S3.
My question is if I have new custom rom versions or if I want to switch to a different rom, do I always have to go back to stock firmware and then install the custom rom or can I directly flash over my existing custom rom ?

New custom rom versions: Unless otherwise stated by the developer you can go ahead and just dirty flash right on top of the current one, but if you experience issues then i'd wipe data and cache and do a clean install.
Switching to a different rom: ALWAYS do a clean install (wipe data, and cache), i can't urge how important that is, while you may not have any issues whatsoever, you definitely could encounter issues because each developer may have different changes, and you don't want stuff to mix and match.

Thanks. So just flashing over existing rom after wiping data and cache will work. Will do that. I do not want to go back to stock rom always as that is time consuming.

You can flash stock roms in CWM, but be careful if they don't include a kernel. If you go from AOSP to Stock, you might get a boot loop unless you also flash a stock compatible kernel, and vice versa. Boot loop is easily recoverable of course, but it will scare new users

[Q] ViperS 3.1.2 + Sensation XE

Hi.
I want to switch to ViperS 3.1.2 but have few questions before I do so. I've never done it before so I'm new to this.
Does it come rooted (or do all ROMs come rooted)?
Is there any instruction on how to do it or just flash it from .zip via the recovery mode (I have CWM 5.x.x installed already)?
And are there any bugs with it such as Wi-Fi problems/tethering, or calls (speaker)?
Also, what if something goes wrong? I've got a backup of my current ROM (stock), so do I just flash that one back or try ViperS' in case it was a mistake on my side?
Lastly, I've heard some people mentioning OTA updates. I'm assuming it's done in the same way as stock ROMs, so you just need Wi-Fi/working internet and the new update will install on its own, or do I have to download the update from here and then do it myself?
Thanks!

Are you S-Off or S-On? If S-Off then you can flash the zip directly from recovery and if you're S-On then you gotta flash 4EXT recovery first and enable smart flash feature and then flash the zip file.
There are no major bugs in the Rom except the ones listed on the OP of the official thread. Enjoy flashing.

I'm S-Off. I've had root earlier but I've installed SuperSU and accidentally pressed Clean SU which has pretty much wiped it. :|

Post your bootloader details to make things more clearer. Flashing a custom Rom doesn't need root access. You can flash it as you're s-off.
What Rom you're using currently? What firmware?

I apologise for not posting, although it may be a bit too late now since I'm already installing the ROM.
So, just wanna know now - do ROMs come rooted, and if I can always go back to stock ROM as long as I have the boot.img/download stock ROM from HTC site?

Yup they come pre-rooted

Thanks for the help, everyone! Managed to install the ROM, despite being stuck in bootloop for 2 hours but it works flawlessly now.

Most roms come rooted, and the rest provide root tools so you have a choice while flashing.
To return to stock look up ruu. An ruu + s on = your device as it came.

If you had flashed Firmware-3.33 before the ROM - you would have had no "bootloops" at all! The most important thing is to have Firmware-3.33

If you made a backup before flashing you should restore it, or else flash the ROM you had before flashing.
Then use "Titanium Backup" and back up your messages (your contacts are automatically synced with your google account, unless you saved them on the phone, but you can change that with the "people" app.
after you backed your phone up, make a full wipe, and flash the new ROM. Install Titanium Backup and restore your messages backup.
Good luck.

Get a download of the ROM you had before, and you can flash it normally. If you had stock, find a download of stock ROM (although Sense 3.6 custom ROMs might actually work too).

Oh no, I thought you wanted to flash viperS. Flash the ROM you had before flashing, whichever ROM that was (but flash that specific ROM, not a different one. My advice from the previous comment was if you came from stock ROM). If you flash the same ROM you don't have to wipe, and then you can back up your phone.

I hope you can operate adb, because the solution I found requires it.
Go to recovery, and use adbto pull the contacts database with the following command:
adb pull data/data/com.android.providers.contacts/databases/contacts.db
It might give an error for a protected directory (but I don't know since it's going to be done in recovery), if that happens, use 'adb shell' and then 'su'. then exit, and you have root access to the device (do it only if required).
Once you obtained the file, it should be on your adb folder. you need to open it with a database app which supports SQLite3 (I won't reccomend anyrhing since I've never used them. but from a quick search I found a few. and searching in the context of reading android databases would give some recommendations.).
Good luck
p.s - It's hard for me to believe this is the simplest solution. It might work, but it's not easy. So others might give better solutions.

[Q] - No Calls or SMS OxygenOS or CM12

OK I am having a problem, when i rooted and followed the direction to install both OxygenOS or CM12 nightly I am unable to receive any SMS or phone calls except after a reboot. Once i reboot any saved messages come through and then once the phone sleeps it stops. I have rolled back to CM11S for the time being. Any steps or tricks to follow to get this issue resolved.

"followed the direction to install both OxygenOS or CM12 nightly" does it mean you are using Multiboot?

No just flashing either one I have this result. Not sure if I am doing something wrong in the process.
Steps:
Wipe all but internal
Flash Rom (then gapps if CM12)
Flash SU
Reboot

Well all i could suggest it, also please flash the CM12 firmware once. In theory oxygenOS and CM12 firmwares are compatible. So flash like this:
Install CM12 fimrware zip
Wipe System, Data, Cache, Dalvik etc without Internal memory
Flash Rom Zip
Flash Gapps
Flash SuperSu
and then let it boot and settle down. Before restorign apps or data, check for any issues again

seems to be sitting stable at the moment, will keep testing. but thanks for the input.

Great! Let me know if the bug persists. And be careful with firmwares. For CM12 roms, just flash the firmware once and you're good to go for all of then.

spoke too soon, after letting the phone sit ideal for a few hours and testing incoming calls\sms nothing came through. restored a backup of CM11S, for the week to have a working device. will keep trying to get to a root cause later in the week. will also open a help ticket with OnePlus to see if there is something I am missing as well since this happens with OxygenOS as well.

Help for for back-up and for new rom installation (newbie :) )

Hi guys, i have a completly stock OPO with CM13.1,
I never changed anything because personally I really like the CM roms, but now after learning that OPO will not be updated to Android nougat would like to install a new rom.
Browsing the forum I found the rom Tuga Power (http://forum.xda-developers.com/oneplus-one/development/rom-tugapower-0-2rc-t3463157) who seems to have a few bugs, is already updated to 7.1 and has all the features i love about CM (such as themes).
Now since I have never done anything like that (except the flash of some recovery of stock updates), I need a hand for backing up (a good app that makes me put EVERYTHING safe), for installation of custom recovery (TWRP?) and flash the new rom and related Gapps.
Thanks in advance

The backup you're looking for a is nandroid backup which can be made in your custom recovery. If you have TWRP, just boot into recovery, select backup, select all the partitions, then start the backup. It'll take a couple of minutes and the backup will be about 5-7~ GBs so make sure you haven't enough space. Another type of backup can be made with the app Titanium backup and it's available on the play store. Your phone needs to be rooted and you need to have busybox installed, but the app will make a backup of all your apps and their data.
After you install the ROM, do a factory reset in recovery, wiping all partitions except internal storage. After that, follow these steps:
1. Flash your preferred firmware (241 is generally the recommended one)
2. Reboot into recovery.
3. Flash your ROM, then immediately flash your GApps package.
4. Do a regular reboot. The first time will take a couple of extra minutes.
5. After it's done turning on, reboot regularly one more time.
And done!
I recommend draining your battery to 0 and then charging it to 100 ASAP to recalibrate your battery, as this will usually give you better SOT.

You think that will be better then Tuga ? Reading on forum i think Tuga is One of the best in terms of Battery/bugs/usability

I've not had a lot of experience with Tuga, so not totally sure. CM 13 has treated me well (except for this time last year when there was a pretty serious spontaneous rebooting issue due to a modern change). Other than that, this has been my exclusive daily driver for a year now.
I don't expect CM 14 to be daily driver material out the gate, but I wouldn't mind being wrong about that ?. We'll see.

Yes, this tool will work to flash TWRP. But you will have to do the backup yourself, as I don't believe that tool supports that function.
But personally, I will recommend you do these steps yourself, as you will learn more about your device and will be able to pin point any errors or to familiarize your self with the process in case a tool is not available in the future.

Yeha i'm looking on YouTube for videoguides, seems not too hard, at least not harder than Kali wich i'm familiarizing righ now, my only fear is the backup, i Have no root and Titanium works with root , but for having root i need too go with Twrp wich needa to unlock bootloader that need wipe ...
