[q] can i flash straightaway?! - Galaxy S II Q&A, Help & Troubleshooting

I'm getting the Galaxy S 2. However, can I straightaway flash a custom ROM or do I need to unlock bootloader first???

It has an unlocked bootloader, thus you can install any custom ROM straightaway.

You can flash straight away, a ROM like Lite'ning will root your phone so no need to root before hand.

[Q] about losing root

Hey everyone, I've been using my hox+ rooted for some time now, never flashed a ROM and was wondering if I update to the new att software will I lose root?
Yes. Just make sure you have a custom recovery and flash the root installer zip. Or if you have TWRP, after a the flash, it will ask to install root.

Know how to flash boot IMG. Sorry I'm a noob any help would be greatly appreciated.
Use this command in fastboot.
fastboot flash boot /location/of/boot.img
If your bootloader is unlock and your phone has a custom Recovery, the official AT&T update won't install on your phone. If you want the update, or you wait for a custom ROM with the update to be available, or you relock bootloader, and flash the latest RUU to recover the original state of your phone. Then you can still unlock with the same token and install a custom recovery to root your device.
Thanks much fellas, you've been a great help!

No, you can flash CWM straightaway.
And don't forget, YOU CANNOT RUN CUSTOM KERNELS ON A LOCKED BOOTLOADER. YOU CAN ONLY RUN STOCK OR STOCK BASED ROMs.
say no to Drugs and ICS!

You can install CWM Recovery without unlocking bootloder but you have to root your phone first.
If you unlock your bootloader, you can flash any custom kernel which is built fir your device which will have CWM Recovery in it. i.e, you don't need to install CWM Recovery separately.
Once you have the CWM Recovery, you can install any custom ROM.
& don't worry, ROMs are built in large packages so that they're compatible with a number of devices. It doesn't mean that whole package will be copied as is to your root. Instead, you'll have some more free internal memory....

tnx, so what do you recommend, unlock bootloader-----flash cwm-----and rom. Kernel and rom are in same file everything could be flashed from device, cwm ?
tnx again
First decide whether you want to unlock your bootloder or not. I recommend you to unlock your bootloder but it WILL void your warranty but you'll be able to do alot more than Locked Bootloder like using custom kernels & you'll be able to flash ANY available ROM built for your device.
So 2 options for you:
1. If you want Locked Bootloder:
Root Your Phone > Install CWM Recovery > Flash any stock based ROM using CWM Recovery.
2. If you want Unlocked Bootloder:
Unlock your Bootloder > Flash any Custom Kernel (Which is compatible with ROM you want to install) > Install the ROM using CWM Recovery.

[Q] How do I root an AT&T HTC One M7

Hi, I'm new to the android community and this has probably already been solved but how do I unlock the bootloader and root an AT&T HTC One which is running android 4.4.2 with Sense 5.5. I want to root my phone but am worried of accidentally bricking my phone. Thanks.
From htcdev.com, you need to get the Unlock_code.bin file. While getting this file, you will also get detailed instructions about how to use that file to unlock your bootloader.
Once you have unlocked your bootloader, flash any custom recovery of your choice (twrp or cwm).
Then through that custom recovery you can flash super user.zip.

[Q] updating to LP on unlocked bootloader

With all the hype on the lp launch, I just realized I have no idea what to do : I got the rom through xpirifirm, and I'm just sitting there like "now what?"
Originally when I got the phone, I created a KK pre-rooted rom and used that on my phone, later on down the line I unlocked the boot loader to use a custom kernel and try different roms, but the pre-rooted rom how-to says it's for "locked" bootloader only, for now I figure I should be fine making the rom following the same process and then flashing the resulting zip to my phone, but I have a few questions :
is this the proper way to do it on UB ? to create a prerooted rom and use the zip file to flash the LP update ?
will I keep my root if I do this ? (I'll use the latest SU binary)
will I have recovery ? (I'll use the latest dual recovery)

Root and recovery on Lollipop

Managed to get my hands on a cheap second hand TabZ in good condition. And although Sony's Lollipop firmware looks and feels nice I really want to go the custom Rom road as it allows me to tinker more with it.
Now is when the situation gets complicated as it seems there is a plethora of versions, some more complicated then others, to root the device and install a recovery on it. My questions to you, anybody willing to clear these things out, are:
1. Does the bootloader need to be unlocked in order to obtain root for a tablet already running Lollipop? (I read in one thread that starting with Lollipop this might not be required anymore)
2. What is the best way of getting root?
3. How do you install recovery? I understand the XZDualRecovery to be really popular but some of the instructions can be mind boggling (the use of Kernel Builder to repack the kernel in order to replace the built in recovery with XZDualRecovery). Is this the same as flashing a recovery every time I install a new ROM before rebooting if I want to still have one (basically there is no permanent one, but changes with the rom you are flashing?! )
Any help would be much appreciated as I am stuck as I have never been with rooting and installing recovery on a device. Thanks!
1&2. Bootloader is not directly connected with Root. Unlocked bootloader allows you to install custom ROMs like FXP, cDroid, CyanogenMod and others.
For rooting stock Sony Rom rooting doesn't usually need bootloader unlock.
For example for 4.4.4 and 5.0.2 firmwares KingRoot will help you to root device. For other firmware, other tools exist.
3. For installing Custom Roms like FXP, CyanogenMod and others you need unlocked bootloader.
XZDualRecovery is mainly used for stock Sony Rom and based on stock roms.
For custom roms you can flash TWRP recovery to FOTA partition which will be permanent and will allow you to install any custom rom.
Also before bootloader unlock, get root and Backup TA partition of your device.
