Hi,
I don't know if this is the correct section to get this question answered, but I'll try:
I have a new tablet, which is not really known at the moment. I managed to root it and next step would be to port Clockworkmod Recovery to it. Since I only found guides where I always have to repo sync the entire CyanogenMod github (which is 19GB+ as I heard), I searched for an alternative where I could save some traffic
I found a clockworkmod recovery from another tablet and wondered if it was just possible to unpack it, modify the recovery.fstab and repack it again.
Is this possible or do I have to modify more than the recovery.fstab? If yes, could you point me to the right direction?
Regards
dump your stock recovery
unpack the stock recovery and save the vold.fstab somewhere.
upload the stock recovery here
http://builder.clockworkmod.com/
get the output and flash`it
if the key`s are not working, unpack the new cwm, and the old recovery, and put the keys from the old recovery.
if you get some mount points erros, you will have to upload also the saved vold.fstab on the clockwork site when you cook the image.
if this does not offer you a good result, you will need to find a similar device (processor, resolution) that has allready a cwm, and try it
the recovery file is ramdisk/sbin/recovery
Hi,
thanks for showing me a way. Unfortunately builder.clockworkmod.com says it didn't find Android magic. This makes sense, as the image is a uImage with lzma compressed data inside. It seems koush's builder handles only "plain" recoveries...
Bad luck
I guess I'll try your second advice and search for a CWM for a similar device, unpack it, replace the fstab file and repack it again.
Thanks again!
hello I have made the porting on http://jenkins.cyanogenmod.com/job/recovery/lastBuild/console
I end up having a zip archive, how can I make my tablet to read that. I have installed cwm recovery and it is rooted. Let me know how can install it and replace my recovery with this.
BTW I have the original stock firmware of my tablet.
let me know thanks
Hi, i have been trying to find a compatible updater-script for my phone to be able to flash a modified stock rom using android kitchen. The way android kitchen modify the update-script to updater-script is not working with my philz touch recovery latest version installed, even if i checkmark the option to use the old update-script method the installation goes thru inside the recovery but i am unable to start the system, it loops on the samsung logo.
any ideas where i can find a compatible updater-script and updater-binary ? i dont know what else i can provide as information to be more clear on the issue. I know a lot of ppl if not all who try to create custom roms are having, searching google did not help and searching the forums either because the results are not for my device specific SGH-M919V and i sure dont want to brick the phone. So far i was able to remove knox, bloatware i personnaly dont want to have in my rom. I am not a coder but i can understand the logics of some scripts.
How would I go about if I want to create my own rom based on the latest samfirm/updato rom?
I have this far downloaded one for s7edge. Unpacked the first zip so I get AP/BL and so forth. I've then unpacked the BL and managed to unpack the boot loader stuff so I have kernel an ramdisk by them self. I then unpacked the ramdisk.. But how do I go on to make this a flashable rom? Preferred is to replace or remove the recovery so I can preserve TWRP. I've done all this so far to get a flashable stock rom that doesn't enforce encryption.. If I get all working I might do more stuff with it
Any help or pointers appreciated!
Hey there,
So I have twrp installed and tried to flash xposed such resulted in a bootloop, tried to install a stock ROM giving me an error, after that I accidentally deleted my system folder when trying too wipe data. I do not have a PC at my disposal, any ideas on what to do? Tried again installing a stock ROM but it gives me an error. I can give more information if needed.
The file seems to be a tar.md5 file but again I do not have Odin at my disposal.
Can someone please help? I really need the phone working.
Edit: if someone else add a backup of the system files would I be able to flash it?
If you can open TWRP, I suggest you to flash the Xposed uninstaller : https://forum.xda-developers.com/showthread.php?t=3034811
I had the same, my device stay on "Samsung Galaxy Core Prime LTE", I opened TWRP with Home + Power + Volume Up, flashed Xposed uninstaller, and now, my device works fine
I hope I helped you

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:
