[Q] Rooting Samsung I9001

Hello.
I bought Samsung Galaxy S Plus from e-shop 2 days ago but it came with orange home firmware 2.3.4 I9001BVKPB, which is without TouchWiz. Some people adviced me to flash the current firmware with I9001XXKPS Android 2.3.6. Before flashing, do i have to root the mobile? If i access the recovery mode after flashing, will it recover the old 2.3.4 firmware? Will i lost warranty? If i unroot the mobile, will i have back the warranty?
Sorry for these noobie questions, i am new to this.
Edit: Does this firmware I9001XXKPS Android 2.3.6 support Czech language?

1. Read the Flashing FAQ.
2. You don't have to root the phone if you are flashing stock firmwares. You need to use Odin in the Download Mode to flash the device.
3. You could flash to any version and revert back to original shipped version anytime provided you know what you are doing.

ya you will lose your warranty but you can flash back to a stock firmware and they won't even know you've flashed a custom rom or rooted your phone

How can I save my current stock ROM before user other ROMs? Thanks!

Warranty will be lost, if you do anything with the phones software or hardware, if you unroot nobody would recognize/notice it. If you dont need a new room, just root the phone

[Q] Changing from CM10.1 to stock rom?

Hello
Just upgraded to a Note II and have sold my Note 1. The new owner wants stock rom, root and unlocked bootloader. Is there any guide for reverting? I could probably just flash a stock rom trough CWM?
I'm just a little concerned about the earlier problems with breaking the storage part on the phone.

you can use odin to flash a stock rom.

1. You are sure you did it this way as said under point 2?
2. It depends.
As far as I know - most base of all base rules is to stick to proper kernel.
Locked BL requires kernel for locked bootloaders.
All parts of ROM has to be consistent together. system, boot, kernel ...
Either for locked or for unlocked BL. Mixing stock and custom ROM parts is very unhealthy.

I think you need to know if the device enters in flashmode, next would be flash a new stock rom ftf with flashtool.
If the steps are OK you should have your device fixed, and have the bad xperience mixing lb ub Kerns could be....
Hope 2 have helpd you

how to backup stock firmware

Hi,
i have an galaxy s5 sm-g900f unrooted (still on warranty)
Before I try a custom rom on it , I would like to backup the original firmware so i can restore it if something happen. I know some original firmwares are out there to download but I would trust my own one better.
I've searched a little bit but i just found some ways to back up just the data (App data +apks ....)
also i've found some method but they need to root the device first but i'm not sure the if i rooted my device and i backed up the firmware and when i restore it, it will be rooted or not.
does someone know a method to fully backup the firmware without root ?

Can't be done without custom recovery, which will void your warranty
The stock firmwares you don't trust, are identical to the one running on your phone right now
sammobile dot com & ODIN will restore stock
But if oyu are going to flash a custom ROM, then you'll need custom recovery anyway, and also void your warranty
Flash TWRP recovery, backup your ROM, flash what you want

Yea, It`ll be identical to how it was when you backed it up, (Speaking from TWRP full backup)

Can I restore stock rom from custom rom without flashing to official stock rom first?

The procedure to restore to stock rom on the internet is to flash official stock first.
Is it possible to restore from backup(backup stock rom before installing custom rom) on custom rom?
what need to backup if the answer is yes?

Not a good idea. You’re asking for troubles.

In theory: yes... You can make a backup in twrp, reatores It and lock bootloader. In real world: Just don't do that. There are several possible problems with It and people are bricking their phones doing a lot less...
