Noobie Question about ICS

I can't post in the development forums so I figured I would ask here:
I understand how to use adb and fastboot, etc.. What I am missing is with the new ICS ROM it states that I must "fastboot flash system system.img"; however none of the ICS zip file I have seen come with a system.img file (just the boot.img).
Am I missing something? Any help would be greatly appreciated..

I used the version available on Rootzwiki... not sure if thats the answer you wanted. I'm running 4.0.3 ICS on my wifi XOOM OC to 1.54. No FC's, reboots or anything of the sort. You'll need to be sure that you have su-install.zip, and other img files needed. As I said, you'll find them all on the rootzwiki website under xoom hope this helps, if not good luck.

You are talking about two different things here. I don't know where to start here you're all mixed up. There are several ways to flash a ROM, you can fastboot flash the .img files such as what you are referencing to. Or you can flash an update .zip file from recovery. The way you flash the ROM depends on the source, if its a bunch of *.img files you use fastboot, if it's a *.zip file you use recovery. Just follow the directions given for installation that are provided with the ROM you are downloading.

Hello, and welcome to XDA! =] Anyways on with your question. There are two ways to flash a ROM to your xoom. One being fastboot/adb, where you use the command line on your computer to send commands to your device and make it do stuff. This is where you use system.img, boot.img, recovery.img.
The second, is CWM (ClockWorkMod recovery) This, as far as im aware, is the most common way. This is where the .zip's come in. Because you take the .zip you put it on your external SD card. boot into recovery (after flashing CWM of course) and flash the rom. CWM is nice because you can also make a 100% snapshot of your internal memory state via making a nanodroid back up. That way if anything messes up you have a 100% backup you can restore at anytime if you need it.
In a nutshell, You use *.img files with fastboot and .zip files with CWM.
Anyways. If you're new to rooting. Please check out these two threads, They'll help you get started. =]

Confusion and/or problem with vendor - Help greatly appriciated

Hello everyone. So I'm brand new to not only xda but rooting and the likes all together. Yesterday I rooted my nexus 6p without issue and I will now list what I used. Twrp 3.0.0 -1-angler, BETA-SuperSU-v2.67-20160121175247. My phone build was MMB29P. then I flashed on pure_nexus_angler-6.0.1-20160315-CMTE and PureNexus_Dynamic_GApps_6.x.x_3-15-16.zip. Now my phone is saying its build MHC19J. I don't know if that is normal, but now I'm confused. When I boot up I get an Android System message saying " It appears your vendor image may be out of date. Please flash the latest vendor image for your device. " So followed the link to the vendor images and I see the list of vendor images however I don't see my build MHC19J.. or am I to get MMB29P? also once I do get it downloaded and load up twrp I see the option to click image and there's several boxes there to check/uncheck.. Do i just check vendor? So put as short as possible I need to know which vendor image i should get and how to flash it from twrp. Thanks for reading and your help will be greatly appreciated.
Also I almost forgot.. Will i need to flash a raido file or anything like that??

The vendor version you need is MHC19I which you can download following the link on the first post on the pure nexus ROM. Flash it via TWRP by hitting the flash img button and then selecting the vendor partition (duh). It's also good to make sure you are running the latest bootloader and radio (the bootloader should be on version 3.51 and the radio on 3.61).

Fixed 6P bootlooping, now i want to update to Oreo

Hi all, I posted this in the 6P bootloop thread, but didn't get a response. As that is a pretty LONG thread, i'm thinking my question may have gotten lost in the jumble.
Quick run down.
A few months back my 6P started the BLOD. I found the fix listed on these pages, applied it, and have been happily using my phone ever since. Phone is bone stock 7.1.2 other than the TWRP recovery and the modified EX kernel for 4 cores.
Since the fix, my phone FINALLY got the OTA update to go to Android 8.0 and i obviously want to get it done. My concern is HOW to do this without causing more headache.
Can anyone point me in the right direction? Should i use the OTA update or download the factory image from Google?
I've got some knowledge as i used to be into the "rooting" scene back in the day, but haven't for a while, so i feel a little lost.
Thanks for any help.

Well, for starters do NOT take the OTA. It will either fail or boot loop your phone. Due to the fact you have a modified boot.img you will need to update manually using fastboot with the full image. Re-apply the modified kernel after you finish updating the partitions, but BEFORE booting the first time. You can follow most guides on how to manually update a full image using fastboot, just add the step of flashing the modified kernel before booting.

Thanks for the reply and the help. If i could ask for a little more help, as this is my only phone.
Can you explain the difference between the modified boot.img and the modified kernel?
If i download the factory image from here (https://developers.google.com/android/images) is it ok to the get the latested one (Nov 2017) or do i need to get the original one (Sep 2017 as i'm on Fi)
Once i flash the factory image, is it going to replace the modified boot image as well as the modified kernel?
Follow the OP on this thread (https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279) in the downloads section there appear to be 2 files i would need, the "Boot.img from stock 6.17, 8.0 firmware" and "EX kernel version 5.03". Am i understanding that correctly?
Like i said, this is my only phone, and i'm probably just being overly paranoid about bricking it, but any clarification would be greatly appreciated.

Use the latest November image. The boot.img contains the kernel and ramdisk, critical files necessary to load the device before the filesystem can be mounted. When you flash the new boot.img contained in the Google image, it will overwrite the patched kernel. You then need to re-patch it by installing EX kernel before booting. EX writes to (modifies) the stock boot.img. There are also pre-modifed boot.img files floating around. You will probably get more detailed help in the dedicated thread. Learning to flash manually (or remember how) is not really a big deal and a necessary skill for modding (and for getting yourself out of trouble). Good luck. :good:

Ok, so 1 last time (sorry)
1 - Downloaded the latest 8.0.0 factory image from google (this contains the bootloader, radio, and partitions (.zip).
2 - Get phone to fastboot and apply the above 3 new images
3- before rebooting, flash oreo4core (new, modified boot.img), TWRP recovery.img
4- reboot to recovery (TWRP) and apply the modified EX kernel
5 - reboot and (hopefully) profit
Am i missing anything, or doing anything that isn't needed?

<<Disclaimer: I don't use the 4 core kernel, so I don't know if it comes with installer script or someone has just modified the latest boot.img>> Unzip the "partitions" zip you refer to and extract those image files to the same folder as bootloader and modem. For example, you can keep TWRP recovery if you don't flash the recovery.img. That is how you preserve your custom recovery. So in other words you'll now have a folder (your ADB folder?) with 5 image files.... bootloader, radio, boot, system, and vendor all in one folder. <<Note: it is my understanding you just substitute the latest oreo4core file (should be boot.img?) If this is true, copy that file into your ADB folder and let it overwrite the stock boot.img. Stop. Copy over flash-all.bat, change the *.bat extension to *.txt and open in notepad. You will see (and can copy/paste) the fastboot commands to get you started with bootloader and radio. Then flash the last 3 (boot, system, vendor). At this point you can reboot into the OS. Since you substituted the oreo4core boot.img file for the stock boot.img there is no need to use TWRP to flash anything. That and since you skipped flashing the recovery.img, TWRP is still there.

Thank for the help! Everything seems to be up and running. I know you said you don't use the "4 cores" (can only assume your either on a different phone or yours isn't affected by the BLOD), but do you know if i still need to apply the EX kernel update, or know of a way to tell if it's already been applied?
Thanks again for all the help. I was pretty much in the right direction, but being as how i'd been away from it for a while, i wanted some backup

I don't think you can flash EX kernel from now on. I think you have to use a modded boot.img that will contain his kernel/ramdisk. This is my guess. You really should be getting your information in the dedicated thread where everyone is actually installing and using it. Google "oreo 4 core" and you will find the XDA thread is the first hit. Good luck. :good:

[HELP] Cannot update TWRP

I have an LG V20 H910 dirty unlocked, rooted, and currently using LOS 16
I bought this phone 8 months ago for the sake of me tweaking with it, but unfortunately it didn't go well
The first thing i noticed was the screen ghosting, then the phone is very slow on stock ROM (H910PR 10f i think), so i rooted the phone and installed TWRP
I did installed the Stock Oreo ROM but i still decided to clean flash LOS 15.1 then dirty flashed LOS 16, and here i am still my current ROM is LOS 16.
I need to install the latest TWRP for me to theoretically install Gamma kernel (cuz mine just goes stuck to fastboot after, i dunno why)
So i thought maybe my TWRP is outdated, so i want to update it, but i can't, it is stuck on fastboot after, just like the kernel
I'm currently on @Phoenix591 TWRP 3.2.3-1 and this is literally as far as i can go, because anything later than that (like the lastest 3.3.1-1 or even just 3.2.3-4) bricks my phone to fastboot.
Can anyone help me with this, please?

Download the newest version from the TWRP thread, and then in your TWRP, hit "install" and then select to install by .img and not .zip and you should be able to flash that way. Otherwise do it through fastboot which I can help you with if you need to. Let me know.

just for kicks (it won't hurt anything, but chances arn't great it'll help... but its something), does the us996 variant of twrp do the same thing?
There's basically no difference besides what the device calls itself (and some minor kernel options) for the purposes of checking what roms should be allowed to flash.
Also just to cover our bases, have you double checked the md5sum of the downloaded ATT twrp image and ensured it matched what android file host shows for it? (if the download was corrupted in such a way as to prevent it from booting properly it might end up going into fastboot from THAT)

KDZ to TWRP flashable ZIP?

I more or less understand what a KDZ is, and how to flash it with LGUP. I also sorta understand that a TWRP flashable .zip file is basically just an archive of a bunch of .img files that TWRP (magically) knows where to flash to on the device. So I can get a KDZ for the stock ROM from LG, or I can get a .zip of a custom ROM such as LineageOS. However I've also seen .zips of stock ROMs such as in this thread by dudeawsome.
What I want to know is, is there a way to convert an official KDZ to a .zip file that TWRP can flash? I'm assuming that is what's done to make a stock ROM available in a convenient .zip format for use in TWRP, but I'd like to know the details of the process. The closest I've found is something called KDZZ by weakNPCdotCom, but it appears that it no longer works and is discontinued.
I want to be able to take any official KDZ and convert it to a TWRP-friendly zip. I also want to remove the laf and recovery images as well since I don't want TWRP overwritten. Can anyone give me the lowdown on this?
