Install a rom without Custom recovery? - Galaxy S III Q&A, Help & Troubleshooting

With Samsungs stock bootloader for the S3, you have the option of applying updates from Cache partition, external storage, and ADB, would it be possible to flash a custom rom (ex. Cyangenmod) by renaming it Update.zip and moving it to SD card and flashing it?

Cant's use stock recovery to flash any custom ROMs.

But if it can flash updates couldn't I trick it into thinking a custom rom Is an update?

The recovery is for flashing ROM updates, not a brand new ROM.

Well thanks anyways.

To install a custom ROM, it is usually necessary to erase the existing ROM before installing a new ROM and stock recovery can't do that.

No, but you can use FlashFire on a rooted ROM to install ROMs or ZIPs

[Q] How to flash a custom rom HELP!!!

I want to flash a custom rom on my sgs2 .....
want someone to help me choose a custom rom and a detailed method to flash that rom(coz maybe different roms have different method).....I'd like to have a nice theme different from the official firmware.....and can i flash an ICS based custom rom to my gingerbread running phone wtih a full wipe or do i have to flash an ICS firmware and then flash a custom rom???
My phone is running with gingerbread 2.3.6 xwkl1 (rooted) !!!!!
Thank you in advance !!!
1) Try a bunch of roms until you find one you like. Not doing so is laziness on your part. Have a look at the development section of the forum, there are heaps of roms there for you to read up on the features & try out.
2) Follow whatever flashing instructions the particular rom you want to try has to the letter.
Resurrection Remix ics is great choice...

most of the roms are in zip format, you just put the downloaded file into you sgs2's internal sd, reboot to cwm.
with the tar format, you need odin to do the job.
i'm new to rooting but i think its pretty much the same way for most devices, for .tar files you need to use odin and if they're .zip you can connect your phone to computer and copy the .zip file onto the root of your internal SD card which basically means don't place it in any folders. disconnect your phone, reboot to recovery, if your coming from another ROM you need to wipe data/factory reset & wipe cache partition, dalvik cache should also be wiped. after that select install zip from sd card or it might say from internal sd card select internal if it does, click select you ROM package (.zip file), the installation will begin, after completion go back to recovery menu and click on reboot system. hopefully it should boot with no problems.
I'm actually using Omega v11.1 ICS with Speedmod K3-16, and it's the best rom I've tried. It's perfectly smooth and stable, and this is the most ICS themed rom. To install it, simply make a full wipe and install with CWM

Custom Recovery

Hi, I have a Galaxy S2 with stock ROM 4.0.3 and stock Recovery. I wanted to know if there is a way of flashing Custom Rom without rooting the phone or ADB. Would this method work? http://forum.xda-developers.com/showthread.php?t=1501719 I would just proceed till the step "Choose CWM.zip and wait until CWM recovery appear." Would this work? i need custom recovery so i can flash a custom ROM.
Thanks again
No you cant flash a Custom ROM from stock recovery, you need a custom recovery and root access on your phone for flashing custom roms
the method you linked is only for rooting, the recovery appearing is only a temporory one from which you can only install SU-Busybox-Installer.zip.

I didn't test it myself, but I think that it will work.
If the custom ROM is provided as Odin-flashable tar file, you don't need a CWM recovery to flash it. Just put the ROm tar file into PDA section of Odin and flash it to your phone.
Only if the custom ROM is available as CWM-flashable zip file, you need to flash a kernel containing CWM recovery first.
I prefer to flash CF-Root kernel from Chainfire with Odin. It contains CWM Manager app and CWM recovery of cause.
When you are in doubt, stick to the flashing instructions of the ROM developer - usually in the corresponding ROM thread.
P.S.:
As soon as you have CWM recovery, create a nandroid/system backup.
So you will be able to go back to your current system, if something goes wrong with the new ROM.
Good luck !
Oh cool, lemme try it

All you need to do is download cwm recovery from here http://clockworkmod.com/rommanager in your SD card and flash the Dowloaded zip from stock recovery .
Once you flash, your stock recovery will be converted to cwm recovery
After that flash any custom rom of your choice. Simple and short

No you can flash any ROM you want, just like any other cwm.
I have used it multiple times, but the Queston is can you do it the first time, before you choose that busy box installer.
Edit: yes you can flash any rom just fine

This is a fix only for who is installing custom ROMs without custom kernel. To install recovery, search for it.
I have had a problem, after flashing Rom, before flashing your zips I wiped cache, and started this problem in recovery:
Can't mount CACHE/recovery/log
then after flashing your zips phone stuck reboting at logo sony, so I have to start from zero, do you know why have that ocurred, is it because wiping cache?

for the xperia sspeed rom for example, you can also use the stock kernel, but why can't i use it for cm10?
That's a stock based rom so you can use the stock kernel. Whereas CM10 is AOSP based so many things in the Kernel are different for example Wi-Fi modules as well as other things

There are infinite posts regarding how to install a custom rom. Firstly you have to root ur phone then install a custom recovery like cwm or twrp and then you have to flash a new rom. system recovery can be used to install recovery like cwm. google it.

You don`t have to have root before flashing a rom as most custom roms are prerooted allready, you just need a custom recovery

Instructions For Installing Pie Roms​
Please Note This Is Not A Root Method For Oreo Or Pie. As Of Now There Is Still No Root Method For Oreo Or Pie. This Takes Some Patience To Install​S8 SM-G950U/U1/W Install Instructions And Files
If you didnt upgrade to V8 bootloaders using odin. I recommend flashing full stock firmware with V8 bootloaders even if you are already on V8 bootloader via OTA update. I feel that maybe something in the OTA from V7 bootloaders to V8 may have corrupted a bootloader file and some people have experienced bricks with trying to update to V8 bootloaders from V7 using the below method so I recommend flashing full stock V8 firmware in Odin before trying this method and just understand there has been a risk of bricking device. Full stock can be found on Sammobile or updato or any other service you can find it. You will have to reroot of course. If you Updated to V8 bootloaders using odin method already then no need to do so again

View attachment Adaway_Blocking_No_Root_Pie.zip
Install zip in safestrap
boot phone back up to system
you will have 2 apps in your apps drawer Host Adblocking and Stock Adblocking
too enable adblocking run the Host Adblocking app it may require rebooting phone to work
too disable adblocking run Stock Adblocking this probably will not require a reboot
what this does is move the system/etc/hosts file to the internal storage of your phone then I symliink the one in the internal storage to the system/etc/host file this way the file can be changed back and forth . If you would wipe data in stock recovery however you would need to reflash the zip in safetrap as a data wipe would delete the host file since it is now located on internal storage

Even though system cannot be rooted you still have safestrap recovery which is basically twrp recovery for locked bootloaders. So with safestrap you can still flash zips. Make backups delete or modify system apps or data and good thing is Samsung apps still work as well as safetynet passes

Hi. So I apologize for any questions that may seem glaringly obvious to y'all but I have been away from the Android world of rooting for a number of years and A LOT has changed. Instead of doing one massive post, I'm going to ask one question at a time because I'm assuming that the answer to one question will also fill in the blanks to other questions....
How do I determine what version of bootloader my S8+ (DTA6 build) is running?
My ultimate goal is to get root. I do not care if I have to use an outdated ROM (in this case, Nougat, from what I can gather).
Thanks in advance.
