So: I'm on a custom kernel,custom rom.
Should I :
1) Wipe Everything in TWRP.
2) Boot into download mode.
3) Flash stock rom
or
1) boot into download
2) Flash Stock
3) Wipe everything in stock recovery
?
In my opinion....2nd method. Then there's a low risk of you damaging the EFS in TWRP. Once you done downloading the firmware perform a factory reset in the stock recovery

Does anyone know where I can get a stock recovery image for a nexus s i9020a?
I tried the file from the large sticky post with all the rooms but it only gives me an error in clockwork mod recovery when I try to restore to that file.
I also tried installing that file by manually selecting the zip but that just put it in a boot loop and deleted cwr. I put cwr back on and that is where I am at now. Anyone know why the file isn't working or can link me to a nandroid for i9020a that will work with clockwork recovery?
Any help is greatly appreciated. Thanks in advance
follow this thread http://forum.xda-developers.com/showthread.php?t=1033269
wipe data and cache with cwm, flash the rom, flash the stock recovery image, and lock the bootloader. you might have to update to 2.3.4 manually though, but everything is returned to stock
You say flash the rom then flash the stock recovery image. What is the first rom I'm flashing?
And a step by step:
Go to clm, wipe data,
wipe catch
(what do you mean by flash rom)
Install the stock firmware
Is this ALL done in clockwork?

I can't give you exact instructions cause i'm relatively new to this so you'll have to read a guide or something. i'm pretty sure that it's all explained in the thread that I linked you to.
here's what I did, but you might want to double check.
-open clockwork recovery (you might have to re-flash it through fastboot)
-wipe data, and then wipe cache
-put the zip downloaded from the thread that I linked you to on the root of the sd card
-open clockwork recovery again
-install zip from sd > let me choose zip (or something) > let the zip install
-flash the stock recovery image through fastboot
-lock the bootloader through fastboot
done. then just download the OTA update for 2.3.4 and you'll be good as new
Hi all. The problem is this, I cyan9 through mobileodin to stock 4.0.4. after that I can not flash with odin 1.85 cwm or root, or other rom. Firmware stack after checking the hash file of rom. Stock recovery can not do anything too flash - freeze. How can I restore it?
I try flash stock 404 with pit, try install cwm from stock recovery and rooting, try diferent stock roms russian,indian,australia. - nothing.....
Have idea... Install cwm from recovery stock and flash cyan9 or 10.... But it's bad idea...
p.s. I'm from Ukraine, and somewhat easy in forum lot of information to read quickly, and a lot of bugs Thanks
Are you able to install CWM Recovery? if so then try these steps:
1) reboot to CWM
2) wipe data/factory reset in CWM
3) wipe cache
4) advanced > wipe dalvik, wipe battery stats
5) install .zip from INTERNAL SD
6) reboot
That was the problem that stock recovery remained. Firmware sink crooked rose. And One refused to flash (rom or recovery - PC freeze ). I have been through Heimdall(recovery iso) flash CWM recovery - and then by your advice. If it was all easy initially - the post would not create. Thank you.
Hey guys,
Right now I'm running latest 5.1.6 with magisk and official twrp.
Question: when I want to start from scratch, how can I wipe the phone properly without getting a bootloop or something. Do I have to wipe inside the Android system or do I have to boot up twrp recovery and use factory reset? Factory reset means all data will be wiped, do I have then to transfer twrp official installer and magisk zip again to the phone and flash them to start a fresh 5.1.6 rom on top of twrp official and magisk?
Thank you
Kind regards
Push
I'd recommend flashing full stock ROM. Thrn reboot to stock recovery and factory reset.
Then reflash twrp/magisk.
Just do a wipe in twrp and reflash the latest ota. A wipe won't erase your internal storage, so your installation files will still be there. (Remember you have to reinstall twrp after flashing an ota.)
So it's the same procedure when I want to downgrade from 5.1.8 to 5.1.7? Should I only do a factory reset in TWRP and then flash the flashable 5.1.7 full ota?
A factory reset will wipe all your files. Just wipe data in twrp.
hello all
I want a clean system install through TWRP but want to keep my apps and data
Is it safe to do the following :
1-boot into TWRP wipe system
2-boot to fastboot then install TWRP
3-boot into TWRP flash new system
4-flash TWRP zip then falsh magisk
Am I correct ? would I lose data if I do this ?
thanks

You don't need to flash twrp.zip if you're going to flash custom rom i think... Only the flashing of official oos will restore stock recovery (correct me if i'm wrong)
If you are just flashing the system partition (system.img) then you will not lose twrp. If you are flashing the full official rom, you will lose twrp. On a custom rom you won't lose twrp either.
You will only lose data if unlocking the bootloader or relocking it. Also, if you fastboot flash-all using the fastboot zip on xda you will lose all data too. Obviously if you select wipe data in twrp you lose it there too.
I backed up my fully stock ROM (Boot, Data, System) and then installed LineageOS14.1 Official. I wanted to go back to stock after a while so I did a recovery. After recovery finished I rebooted to System but it just opens up TWRP again. Tried wiping Data, System, Dalvik, Cache and doing the recovery again but it still goes straight to TWRP. What do I do?
You need to flash stock ROM via Odin.

Could I flash stock ROM via Odin then flash TWRP again and then do the restore of the backup? It would be the exact same ROM. I had some notes taken so I need that data.
EDIT: I managed to do it by installing the sam stock ROM and then flashing Data on to it. Got all my stuff back.
