[Q] create flashable zip from rom dump? - Android Q&A, Help & Troubleshooting

DEVICE: LG REVOLUTION (VS910V6)
MY RECOVERY PARTITION IS GONE, BUT I DID FIND A ROM DUMP OF THE SHIPPING ROM FOR MY DEVICE. ITS A ZIP FILE. IS THERE SOME WAY THAT I CAN SOMEHOW CREATE A FLASHABLE ZIP FROM THE DUMP FILE TO BE ABLE TO FIX MY PHONE? MY PHONE IS PRETTY OLD. I HAVE TRACKED DOWN A HANDFUL OF DIFFERENT FILES FOR MY PHONE AND I WOULD HAVE FLASHED ANY OF THE OTHER POSSIBILITIES OF COMPATIBLE ROMS, FACTORY FIRMWARE, ETC. THE PROBLEM WITH THAT IS FOR EVERY FILE I FOUND THE DOWNLOAD LINK FOR, IT'S OUTDATED AND DOENS'T WORK ANYMORE. SO I'M HOPING THERE MIGHT BE A POSSIBILITY GOING THIS ROUTE.....? ANY SUGGESTIONS WOULD SURELY BE APPRECIATED!! :fingers-crossed:

SGSII Stock Calculator

Hey guys, keeping the topic's size tiny, any of you can provide me with SGSII's stock calculator APK and the ODEX file? If yes, thanks in advance.
BUMP
Anyone?
You should be able to get the file from any Stock ROM.
Can't you just head over to "/system/app/", copy Calculator.apk and Calculator.odex, zip it and upload here. Since ODIN flashable files cannot be extracted (I believe).
If you take a look at my signature you could see I'm not on Stock ROM, so I can't help you...
But you have several ways to achieve what you want:
1) Get it from Stock ROM: You CAN mount .img and zImage files with a little help from our friend Google.
2) Nandroid your phone, install Stock ROM, get files and restore phone.
3) Wait very patiently for some user that will read this post and has an untouched Stock ROM installed in the phone.

ROMs dont have an update.zip

Hey Guys,
I'm in need of some really n00b friendly advice.
When you flash a new ROM (i.e. CM9) in CWM the tutorials tell you to flash the file named Update.zip. My problem is that I can't seem to find one in the zip file I downloaded for my xperia mini.
I downloaded FXP131, and found the zip file to contain a boot.img, which will be the kernel. And 2 other folders named META-INF and System.
I know how to flash the kernel and expect it was just left in there for easy transportation.
But where in the world is 'update.zip'?
Am I meant to unpackage the kernel then re-zip the META-INF and System folder and then call that 'Update.zip'?
I've flashed roms for some of my other devices before, but they've always used flashtool or samsungs flashtool.
Please help me guys, I don't like sounding this inexperienced
update.zip
I'm wondering if the ROM I am trying to flash needs to be renamed as update.zip in order to work. It is krook's v.6 of JB for the Lenovo K1 tablet. Since the download site has to distinguish between wifi and 3G versions, as well as nvflash versions there are a number of different filenames, however does it need to be renamed after putting it on my SD card?
Generally speaking "update.zip" is used as a generic name. For example the update.zip I just flashed is actually named "rascarlo_maguro_ota_2012-11-01.zip". When you flash a custom ROM in a custom recovery you should be able to browse & flash whichever file you need.
The FXP131.zip file that contains the boot.img and 2 other folders named META-INF and System is the "update.zip"
solved
My problem was an incomplete download. I compared file sizes, and checked md5sums and determined the correct ROM and it is now in the middle of finishing the upgrade/optimization process.
Thx

[Q] Problems signing an update.zip

Hi! I'm trying to help a friend of mine who's phone is stuck on a bootloop. Problem was she flashed Pimp My Rom stuffs but she did not download the uninstall flashable zip as well. She does not even have any clockworkmod recovery. The phone's manufacturer is totally not mainstream and does not have any update.zip available. What I'm trying to do for her is to create a flashable update.zip that's flashable via stock recovery. We have a system.img and I'm aware that we can create an updater-script. The problem is, I don't know where the system partition is. Any way we can do cat proc/partitions or mount via recovery to find out where it is? TIA!
UPDATE:
I found it! It turns out to be at dev/block/mmcblk0p12. The problem that I'm having now is I'm getting errors whenever I attempt to sign it. I tried different tools--sign em, auto signer, Sign+...all to no avail. Any ideas?

[Q] I broke it

Hi guys!
I was hoping one of you could help me.
Yesterday i modified a build.prop file on my NextBook EBM8000ND (Next800T) tablet, causing it to get stuck in a bootloop every time it's turned on. I've been searching the Internet all day long but it's hard to find support when you have a device which no one in the world uses . It was rooted but I did a factory reset hoping that it would fix it. It didn't and now it's also unrooted. I tried to make a custom update.zip with the backup of the original build.prop file but the stock recovery simply refuses to load any update file. It always stops at verification. I used 7zip with store option. I tried signing the zip, I even edited the updater script to only print some text on the screen but the recovery still wouldn't load it. I tried to find a way to install CWM using sdcard but with no luck. When i tried to use ADB in recovery the device says: "failed to open driver control: No such file or directory". It might be worth mentioning that I found my device's ROM online with boot.img and recovery.img files and a .tar file which contains the original system folder.
Is there any way to make the stock recovery (since installing CWM or TWRP seems impossible) read my update file? Or is there another way to fix this? I only need to replace that single file.
Hoping to get help soon.
Cheers!

How to flash only stock recovery? how to convert "recovery.img.lz4" to "recovery.tar"

How to flash only stock recovery? how to convert "recovery.img.lz4" to "recovery.tar"
Hi all,
I am fairly newb in installing custom ROMs, so apologies if Im misusing any terms. Some time ago I wanted to move a priv-app to system-app, without rooting. I managed to flash TWRP on my Samsung S8 G-950F, and from there moved private app to system app.
Now I would like to go back to the stock recovery img, but I don't know how or if it's even possible. The reason behind this is that my company is deploying Android Work Profile and it is detecting the custom ROM (I assume it is specifically detecting the custom recovery partition)
I tried to find the respective recovery.img for my current stock ROM, but was unable to find it. I can only find for older versions, and from what I read, you can't install older recovery with newer ROM
I can only find the full stock ROM, in .tar.md5 format. opening this with 7zip, I can see the recovery.img.lz4
How do I flash this without altering the OS partition?
Thank you in advance,
Rhaswar
@Rhaswar
Look inside here.
thank you @jwoegerbauer, I have seen this article and it mentions a file called recovery.tar
I don't have that, what I have is the recovery.img.lz4
Is there a conversion that can be done?
Thank you
@Rhaswar
