I think we have to relock the boot loader..

The zip is too large. If I download the OTA on phone, is it the same size or is it a smaller file size?
And if I manually flash from recovery, don't I need to clear cache?

Hi
The message is very clear:
Your /system partition is RW (read write)
Thats becouse you rooted the device and enabled RW on /system.
Put the /system partition back to his stock state (Read only) and you should be good to go
Cheers

[App] flashing boot and recovery on Kindle Fire HD

FLASHING WRONG IMAGES CAN DAMAGE YOUR DEVICE SO USE THIS APP ON YOUR OWN RISK
fire flash is an App for flashing boot and recovery partitions on both versions of Kindle Fire HD. Optionally it also installs a simple Open Recovery Script which gets executed after entering recovery mode. In script only wiping system/data/cache and installing ROMs (.zip files) are supported.
Usage: download files you want to flash (boot image, recovery image, ROM .zip files). After downloading files, select them and check appropriate options. In attached image there is an example for flashing Hashcode's bootloader + TWRP + stock ROM v8.1.4 with installed stack override on a KFHD8.9. After all files are selected and options checked as shown on the image, first tap Flash,install script button and then Reboot into recovery button. All required files can be found in Hashcode's threads.
Tomsgt made a video http://youtu.be/a1bLCuQN0-U which shows how to use the fire flash. Thanks.
Note: more than one .zip file can be selected. To remove a file from the list, select the same file again.
Update v1.1
-added support for system version 7.3.0 / 8.3.0:
: if current bootloader is not 7.2.3 / 8.1.4 a red warning is displayed and check box for flashing 7.2.3 / 8.1.4 bootloader is enabled.
: unless you are sure your current bootloader is not 7.3.0 / 8.3.0 bootloader 7.2.3 / 8.1.4 should probably be flashed - check the checkbox.
-works on CM10.1
-every flashed partition is read back and verified
-shows progress when flashing
Update v1.01
-added some feedback after pressing Flash,install script button
-(hopefully) resolved problems with open recovery script

can flash for example tweaks and sound tweaks like acid audio engine that come in a zip?

fire flash generates a script which is then executed by TWRP. If tweaks can be flashed from TWRP then yes. Leave boot and recovery image 'Not flashed' and don't wipe anything in OpenRecoveryScript section. Select your .zip file(s), press Flash, then reboot into recovery. This app only simplifies (a few) tasks that can be done in TWRP and makes intalling boot and recovery partition realy easy.

yes TWRP does the unzipping. If you only need to unzip some files into the /system dir this app perhaps isn't the best choice.

device must be rooted for this App to work.
Works good. A couple things to note:
1. It gives no indication when you click the "flash, install script" button that it's done flashing. I ended up clicking it twice...
2. Even though I selected to wipe the cache/data/system and install the new IS zip file, it did not work. I rebooted to TWRP ok, but had to wipe and flash manually...
But, I'm definitely not complaining about anything cuz it got my second boot loader installed without me having to buy a fast-food cable first!

Good news I'm rooting my Kindle fire HD today for sure

Awesome work. My plan is to backup the current image before flashing any new ROMs. Using this script how can I just flash TWRP without changing anything else? If I just flash recovery partition alone, would it do the trick for my use case ?

Also I think this thread deserves a place in kernel Dev section as I happened to find this by accident. I don't generally browse Apps Dev section but I did and was to happy to find this thread.

I was able to do it without flashing any other zip files(just boot and recover images). It takes a while to boot into recover though (after the "kindle fire" logo turns blue).
Thanks for the good work.

First download the kfhd7-freedom-boot.img and the TWRP Recovery from this post:
http://forum.xda-developers.com/showthread.php?t=2128848
Now move those files to the storage on your KFHD7, install the fire flash APK and execute it, select the files and check the "Apply Stack override" box and the "disable recovery auto update" just like the picture on the OP.
now execute it by pushing the "flash install script" button and Wait! (it do not says its done so i wait like a full minute)
now do a reboot and the boot logo will turn blue and the you push volume up and then you will be in TWRP
hope it helps.

[TUTORIAL][D802] Root, install recovery and update bootloader for NEWBIES/NOOBS!

Hello,
Many people have problem with bricked device because they complied many diffrent tutorials and broke their G2.
I will explain you how to root stock rom/update bootloader and back to stock via lg flashtool.
Perform operations step by step
Okay, so first thing - ROOT STOCK LG ROM.
1. Stump ROOT (Without usb cable, working with 20h ROM)
Stump Root v1.2 (Newest version)
-->> Download Stump ROOT v1.2 <<--
Go to settings>general>security and check "Unknown Sources" to install external APKs.
Now install Stump ROOT app from download link. (In installation progress Android will ask you for install permisions because this integrate in system code. OFC ACCEPT)
Open Stump ROOT and press GRIND, then wait sec and press BruteForce, after 1-2 min your device will restart and now u got ROOT, u need install -->> SuperSU <<-- from market.
2. Install TWRP for your device. (Autorec)
-->> Download AUTOREC <<--
Okay, it's easiest step, just install Autorec application (Be sure it's for your model in file name!)
Open, accept and flash.
This way will downgrade your bootloader and kernel. After device reboot u have already ROOT and TWRP.
Now u can update first your TWRP to newest 2.8.5.1
-->> HERE THEARD WITH NEW TWRP <<--
If you download new TWRP, then u can easy flash it via -->> Flashify <<-- app from market. There select recovery>zip and select your new TWRP, it will reboot device to recovery and flash. (BE SURE IT'S FOR YOUR D802 MODEL!!)
3. Update bootloader. (IMPORTANT!!! U ALWAYS NEED UPDATE BOOTLOADER WITH VERSION ROM WHAT YOU ALREADY HAVE, IF YOUR ROM V20H, USE 20H BOOTLOADER, IF YOU HAVE 20D, THEN USE 20D BOOTLOADER OR UPDATE YOUR DEVICE TO 20H!!)
Now u need becareful, because it is easy way to brick device if you will not perform tutorial.
-->> Download v20h bootloader <<--
Download bootloader to your memory storage in device, and open flashify, press Menu button and Reboot Recovery, when it will reboot to TWRP, press INSTALL and select bootloader v20h zip file in path you downloaded it.
Now reboot device and Enjoy ROOTED device with newest bumped TWRP and newest bootloader.. AND NO BRICK )
Enjoy your powerfull device.
I will update theard with new steps like install kernels, back to stock step by step, easiest way to secure your device.
I know there are many tutorials, but we have still many people on XDA with problems like QS_BULK device, 9008, secure verify problem etc etc. So this is way to bypass every danger things.
Im not creator of any used in this tutorial mods, i just complied few theards to few easy steps

Hi good Job!
I have Two questions.
Can i upgrade my twrp Version with flashing the zip file in twrp?
Which Bootloader version use cyanogenmod 12?
Thank you!
A few additional info for the D802 variant:
-You don't NEED to change boot loader if you're fully on stock unless:
--You plan to use AOSP Lollipop
--You use any JB based ROMs (they should say in their respective threads for the D802)
-If you stick with the KK boot loader, only flash BUMPed flashables (they should state if they use this method)
-I recommend to use Blastagator's TWRP as it has thermal protection that stock TWRP doesn't have
-Only flash ROMs/any other flashables while the phone is cool
-Most ROMs can use the KK modem unless stated otherwise
Correct me on any misunderstood/incorrect information

Ok, good. I liked your tutorial, pretty informative.
Hello, i'm stuck at this step :
"3. Update bootloader. (IMPORTANT!!! U ALWAYS NEED UPDATE BOOTLOADER WITH VERSION ROM WHAT YOU ALREADY HAVE, IF YOUR ROM V20H, USE 20H BOOTLOADER, IF YOU HAVE 20D, THEN USE 20D BOOTLOADER OR UPDATE YOUR DEVICE TO 20H!!)

Edit : i flashed the rom without KK bootloader and it worked
-> I Was on 20H. I rooted, installed twrp, updated twrp. I've flashed 20d KK bootloader and now, secure booting error
I have access to download mode. What can i do do boot normally ? (i know i could probably flash a kdz but i don't really want to)
i cannot enter into the twrp by pressing the vol down + power, it just ask me whether i want to format, this means i still do not have twrp ?

You already flashed TWRP right? If so then you need to confirm it twice with the power button. It says like format data/factory reset but it will boot into the custom recovery.
please help me...i have a lg g2 d802 32gb model ..its a traded phone...when i got the phone it was running 4.4.2 kitkat the phone was rooted bt there was no suprrueser app i installed the app and then i flashed recovery with autorec now whenever i open my data or wifi and use my phone for some minutes my screen becomes unresponsive is it due to the jellybean bootloader that the autorec installed or something else please help me...
Recovery combo gone
The thread seems like dead now, but maybe I get help .
I flashed 20H and now there is the recovery combo, when I try pwr + volume down it simply reboots . The recovery is instaled, but I only can access it from software (that now is corrupted, so, soft brick).
Wrong combo

You're not soft bricked, it's just that key combo changes in 20H, new combo to enter recovery is vol down + power key, As lg logo appears, release keys and press vol up + vol down and you can easily access twrp
and i ran intro bootloop.. help!
I'll update theard soon to aosp/lollipop support, bootstacks explains etc.

Any beginner friendly guides on unlocking bootloader and installing TWRP etc.?

Hey guys,
I'm still running the stock EUI ROM and getting pretty sick of it.
I've looked at getting my bootloader unlocked and installing TWRP but it seems pretty complicated for this device and what information I could find didn't work for me.
Can anyone show me some noob friendly guides on getting this done?
Much appreciated!
What?!? I never had a phone which bootloader unlocks easier than in Le Max 2. You have a special switch for that i developer options. That's all. Next you have to restart your phone in bootloader mode and flash desired recovery using fastboot commands.

Wow, I didn't know that's how you unlock the bootloader. Sorry like I said I'm not very familiar with this device yet. Thanks!
As far as using fastbood commands I tried that but the drivers didn't seem to work on my PC. I couldn't get any of that to work. But I'll keep trying.
If you have anything like Samsung Kies or HTC Sync, etc. installed on your PC, you might try to remove it and reinstall drivers using "15 seconds ADB installed".
i just posted this yesterday,. i guess i could have chosen a better title... do you have any suggestions?? (maybe "full guide: adb, fastboot, twrp recovery, backup, flashing"?????)
http://forum.xda-developers.com/le-max-2/how-to/protocol-backup-stock-rom-flash-stock-t3517151
@thielek what windows do you have? I can suggest something if you have win7, for win10 you can find a guide in some other threads.

Hey, this looks really good!
Thanks I will definitely give it a read and try to get this sorted. I'm pumped to get that CM 14.1 ROM when it gets a few more of the bugs sorted.

No, actually you need to disable the signature verification if I recall it right. I can't find the thread for win10 driver installation right now but for sure I have seen it on xda for LeMax2
Here is the tuturial for noobs (I was noob too and I wrote it for people like me):
Here is the quick tutorial for users like me:
1. Enable USB Debugging
2. Connect phone to the computer
3. Unzip this https://www.androidfilehost.com/?fid=529152257862669609 and run LE_X2_fastboot.exe
4. Wait until it say "Press any button to reboot phone" and just press random button
5. Your phone will boot into system
If you want change to China 21s with SuperSU, you just have to:
1. Turn off your phone
2. Press VolumeUp + Power button - it's gonna boot you to TWRP
3. You can now upload the 21s.zip and SuperSU-v2.78...zip files to your phone from this thread: http://forum.xda-developers.com/le-m...a-rom-t3492640
4. On your phone go to Whipe and whipe all data (swipe blue arrow)
5. Go to Install and choose 21s.zip and wait - when it ends it's gonna boot you to the system
6. Turn off your phone and again boot to Recovery (VolumeUp + Power button)
7. Choose Install and choose SuperSU.zip and there you are!
Now you're gonna have China 21s with root and SuperSu!

Wow! That fastboot program was amazingly simple. Thank you! How did I know find this before. The other guides are very long.
So that installed cuoco92's ROM as well as TWRP. Do you suggest using his ROM? That second link you provided in the next paragraph didn't work.
I was looking for a very clean and vanilla android like ROM. I hate EUI and am excited for that CM 14.1 build but it's not ready yet.
Thanks again very much!

The process I am aware of is
1. Unlock bootloader
2. Install twrp (or any custom recovery) in fastboot mod
3. Flash SuperSu zip to get root access.
Can you please explain in your tutorial the first paragraph can do this? I just want these 3 thing to do mentioned above. Thanks.

[TWRP OFFICIAL] [3.2.1-0] c9ltechn/SM-C9000 Galaxy C9 Pro

TWRP for C9LTECHN/SM-C9000 Galaxy C9 Pro
Special Notes:
1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options).
2. KNOX will be tripped once you flashed custom binaries to your phone.
(Your warranty may be voided. However this may not affect you if your country forces Samsung to provide hardware warranty regardless of software status.)
3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
(You can flash custom ROMs if you want to keep the OS up-to-date.)
PLEASE BEFORE YOU FLASH ROMS MAKE A COMPLETE BACKUP OF YOUR SYSTEM INCLUDING EFS SO YOU DO NOT BRICK YOUR MOBILE
WHAT IS TWRP?
Team Win Recovery Project is a custom recovery for Android devices.

2) Go back to the main Settings page, scroll to bottom and select“Developer options” from there.
3) Under Developer options, look for “Enable OEM unlock”checkbox/toggle and make sure you Check it or turn it ON.
4) Now Boot your Samsung Android device into Download mode.To Do So Follow the steps below
5) Switch off your device.
6) Press and hold “Home + Power + Volume down” buttons for a few seconds until you see a warning screen.
Press Volume Up on the warning screen to accept it and boot into Download mode.
Once your device is in download mode, connect it to the PC with a USB cable. The Odin will automatically detect the device and show an “Added!!” message. If not then your device is not connected properly
7) Now click on the AP tab on Odin window and select the TWRP recovery .tar file that you downloaded for your device.
8) Click the Start button on Odin to start Flashing and wait for it to finish the process.
Once it finished successfully, a pass message on the Odin screen will pop up

Thank you. I have already installed it.
I have flashed TWRP, formatted Data twice, flashed no-verity-opt-encrypt-5.1.zip, flashed SuperSU and after that I can mount Data. But after a reboot I can't anymore? Am I doing something wrong?

I can flash files but cannot mount Data. I presume it is still encrypted despite being formatted twice?
Format data and reboot to recovery

So in TWRP format Data and then reboot again in TWRP.
And then flash SuperSU and no_verity?
Ok, I formatted Data twice in TWRP. Mounting Data works.
I flashed SuperSU in TWRP. Mounting Data works.
I flashed no_verity. Mounting Data works.
I rebooted into TWRP. Mounting Data works.
I rebooted into system and then switched off and rebooted into TWRP. Mounting Data does not work.
What am I doing wrong?
Correction:
I have now used this no-verity-no-encrypt_ashyx file:
https://www.androidfilehost.com/?fid=24591000424951049
And now Data stays decrypted!
I do have a stock debloated rom that is made out of HK firmware if this community is interested, I can put it up. All I see is you guys using Aurora. Anyone interested or do you all want to stick to Aurora rom?
I tested it few days, it works perfect and it is perfectly debloated
Please share Travis. Thank you for your work.

no god no, HK firmware has gapps built in like normal. I'll tweak it up some more and release it today on a separate thread. Right now I'm trying to get kernels to boot-up since they compile fine.

[GUIDE] Downgrade from MIUI Android 11 Beta Stable to Android 10 Stable using flashable firmware

This might help you after realizing that you want to install custom ROM again after upgrading to android 11 MIUI but you cannot install android 10 or 11 based ROM and stuck with either boot loop or android rescue party.
WARNING: This might wipe every writable partition. Charge your phone at least 20% or more to prevent from destroying these partitions.
Instructions:
1. Download firmware from here
2. Download full ROM (either recovery or fastboot) from here
3. Save the firmware zip file it in either internal storage or sdcard. Reboot to TWRP afterwards
4. Tap install and find the zip file in your storage and install. Wait for a couple of seconds to get done.
To install full ROM
Recovery
1. After installing firmware from recovery mode, don't reboot. If you reboot the system it will fail to boot. Boot to fastboot if you fail this step and flash a recovery image. Proceed with next step.
2. Install full ROM flashable zip from sdcard or internal storage.
3. Format /data. Reboot.
Using fastboot
1. Boot from fastboot mode
2. Extract full ROM fastboot zip file.
3. Open miflash and locate the fastboot folder.
4. Choose flash_all. Click start.
5. The phone reboots itself. Boot to recovery mode and wipe data.
All done. The phone is now downgraded from android 11 back to android 10.
Note: I got 2 anti triggered when attempting to downgrade the phone using recovery and fastboot without installing firmware zip file first. RIP me I guess I voided my warranty anyways so doesnt matter as I already applied some insurance for my device.
TL;DR: Installed Recovery will get erased as I mentioned in WARNING. Please don't skip every step.
Edit: since it made confusion, I split steps for recovery and fastboot mode.
Has anyone tried this procedure?
Im on 12.0.6.0(EU). Bootloader locked (wait 3days) so no TWRP. Want downgrade to 12.0.8.0(EU) and flash Pixelexperience ROM.
It will work?
I'm a bit confusing... Links inserted in first 2 points seem to be the same link. So what I've to download exactly?
I'm on 12.0.7.0 Android 10 but I'm curious to try 12.0.6.0 Android 11 stable beta released some days ago...

Its not the same. First one is cca. 80MB of size while full rom is 2.4GB for recovery and 4.4GB for fastboot.
I did this method yesterday and its working. No problems whatsoever.
The only thing i would add is you need both versions of rom - recovery and fastboot. Recovery when you flash for the first time in recovery and fastboot when you flash with Mi flash.
And my advice is, android 11 miui is really bad. Its not finished, it stutters a lot, u can't use third party launchers with gesture navigation (at least in my case, Nova lanucher), performance is bad.
Not worth any time.

did you try to flash firmware file from twrp recovery first? also that error means that a checkpoint failed which you need to disable or remove in configuration settings.

i only tried recovery method and it works fine after days of trying. 12.0.6 android 11 is still buggy and miui needs to fix it a lot. most of apps are not well optimized for this flavor.
Today unlocked bootloader. Flashing 12.0.8.0 (i have 12.0.6.0 A11).
Everything work perfect. No bootloop, bootloader relock and works fine
People are probaly skipping some steps.
1. Download Firmware small size files
2. Download full Firmware, both - fastboot and recovery (put it on SD card, small and recovery)
3. Install Twrp or Orangefox recovery (download it from somewhere)
4. Enter into recovery and install small firmware FIRST, dont reboot, install big firmware (recovery version) SECOND
5. do not reboot
6. format data
7. Now reboot into fastboot
8. Extract fastboot firmware zip into new folder on desktop
9. Start Mi flash, select that folder where u extracted files and tick "clean only" on the bottom of the Mi flash if u want to leave bootloader unlocked and from drop down menu near that pick "flash_all.bat".
Thats how i did it.

i did the same, but looking to partitions of system, product and vendor, i understand that flashing the files via recovery and fastboot they dont write in that partitions.
looks like the partitions are read only. thanks
I try to flash a custom rom like arrows os via recovery , the rom shows the boot logo of arrows rom, and then bootloop.

Did you flash it from the built-in recovery or with MiFlash? (My 167 hour waiting period ends tomorrow)
Solved people. change the version of the Mi Flash.
