How to root the CDMA Hero

Ok everyone. First off do not update your phone if Sprint offers an upate. I don't think they are going to but if they do anytime soon and you update this exploit could likely be fixed. When updates are released the devs will make updates that keep root so do not update!
That said, this is a very newbie guide. This is meant for Windows but I will post instructions for linux as well (Ubuntu). I just need to warn you that I can't adb into my phone from Ubuntu so I have to do it through Windows. Don't know why it doesnt work but it doesnt. Mac users you can always (assuming you can get it to work in Ubuntu) download a live cd and boot into Ubuntu to try this. I don't have a mac (nor do I want one) so I can't give instructions (though I assume they should be relatively the same).
Step 1:
First you need to download the Android SDK. It may soumd confusing but it's not. There are tools in here that we need. You can get it from http://developer.android.com/sdk/index.html. This is a modular SDK and all the tools we need are in this download. Once downloaded you just need to extract it in a directory of choice.
The next thing we download is asroot2. This is a script that was developed that runs an exploit in Android's linux that allows us to run root. The link for that is here: http://forum.xda-developers.com/attachment.php?attachmentid=244212&d=1257621154. Unzip that file and place it in a directory of your choice. Also download http://www.androidspin.com/downloads.php?dir=amon_ra/RECOVERY/&file=recovery-RA-heroc-v1.2.3.img and place that into the same directory you extracted asroot2.
Step 2:
Connect the phone to the USB port.
Ubuntu is easy for this (again assuming it works for you). Simply open a terminal and cd into the directory that you extracted the sdk into. Then cd into the tools directory. Then run the following commands:
sudo ./adb push /directory_you_placed_asroot2/asroot2 /data/local/
sudo ./adb shell chmod 0755 /data/local/asroot2
/data/local/asroot2 /system/bin/sh
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4755 su
If all goes well you should be presented with a new prompt. This is the linux terminal built into Android. This will allow us to execute all the commands we need to execute because the asroot2 script gave us root access.
In Windows it is a little more difficult. You have to first install the driver for the phone. When Windows asks you for the drivers direct Windows to the directory you extracted the SDK into. You should see a folder called usb_driver. If you are running the 32 bit version of Windows select the x86 folder. If you are using a 64 bit version then select the x64 folder. Then select the android_usb.inf file. This should install the drivers.
If running XP or lower you will need to go to the start menu and click run, then you enter cmd and press enter. If Vista or higher you will press the start button and type cmd and press enter. When you are at the command prompt you cd to the directory you extracted the sdk into. Then cd into the tools directory. Then execute the following commands:
adb push /directory_you_placed_asroot2/asroot2 /data/local/
adb shell
chmod 0755 /data/local/asroot2
/data/local/asroot2 /system/bin/sh
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4755 su
Now your phone is officially rooted! We arent done yet though. Now you need to flash the recovery image. If you are still in adb shell type in exit until you are out. You should be in the directory where you extracted the recovery image. If not go there. Type in the following:
adb push recovery-RA-heroc-v1.2.3.img /sdcard/
Once that is done, type in adb shell (or sudo ./adb shell in ubuntu). If your command prompt is a dollar sign then type in su and press enter. If it is a pound sign you are good. Then type in the following:
adb shell flash_image recovery recovery-RA-heroc-v1.2.3.img
Once that is finished you are done. To reboot into recovery type in adb shell reboot recovery. You should reboot into recovery mode. Right now there is not a lot you can do but once we have some devs who make some roms then we will be well on our way to an even more awesome phone. Any questions please ask away. Also, I am sorry if this tutorial is hard to understand or badly laid out. My daughter is crawling all over me so it's hard to type or think. Good luck all and thanks to everyone who rooted this phone and made the recovery and did such a great job!

Is this the right command, every time I try I get : "adb: not found"
The transfer to the sd card seemed to go fine, and I am @ root (#).
Am I missing something?

You beat me to it!!!! I was planning on laying out the steps to make sure I had my head on straight.
To continue with your guide: (The following are questions, not procedures)
1. We run a Nandroid back up to lock in our stock ROM so if we ever do something stupid, aka brick the phone, we can push this back on?
2. What comes on the SD card? Is it needing to be backed up when I go to a 16GB class 6 card?
3. Insert the new SDcard and use the ext2/swap/fat32 script
4. convert ext2 to ext3, (now ready for apps2SD?)
Anything else you can add would be nice.
Again thanks for the steps! They are clear for me.

Sounds like you need to add the directory where you have adb to be added to he path. is your adb in the same dir as the image?

You may currently be in adb shell already. If you are showing the pound sign this is likely. The command is supposed to be run outside of adb shell. Try the command below:
flash_image recovery recovery-RA-heroc-v1.2.3.img

I apologize, but that went right over my head.
I have used this command to copy the image to the sd card.
Code:
adb push recovery-RA-heroc-v1.2.3.img /sdcard/
I got this output:
Code:
C:\androidSDK\android-sdk-windows\tools>adb push recovery-RA-heroc-v1.2.3.img /s

1640 KB/s (3352576 bytes in 1.996s)
I then do the following with the noted result:
Code:

$ su
su
# adb shell flash_image recovery recovery-RA-heroc-v1.2.3.img
adb shell flash_image recovery recovery-RA-heroc-v1.2.3.img

Any help as to where I making my mistake would be greatly appreciated.

Yes. A nandroid backup completely backs up every piece of information on your phone. It is a complete image of your phone and if it needs to be restored for whatever reason you just load up recovery and can restore it the way it was before.

What do you mean exactly? The only thing that gets copied to an sd card is the nandroid backup so yes, when switching to an sd card just do another backup. Or you can also copy the nandroid folder from your existing sd card to your new one.

Yes and no. Just run the ext2/swap/fat32 script and it should be ready for apps2sd. You can convert to ext3 if you want. Generally on normal hard drives ext3 is faster, however there has been some controversy with that on android phones. As for converting to apps2sd, right now the best way is probably the manual method which I can write up a tutorial on as well. The dream forum has some good tutorials on it as they were the first to do it. I actually need to go back and re read some of those because it's been so long since I did it. I tried the apps2sd apk but that didnt seem to work for me.

Yeah. The problem is that you are trying to adb shell twice. After you adb push then just run the command adb shell flash_image recovery recovery-RA-heroc-v1.2.3.img. That should work.

yes he left out the /sdcard/in the path and if you are in teh shell you don't need the adb portion of the command.

Ok. Most likely you dont have the recovery image in the directory. Try this. Copy the recovery image to the tools directory of the sdk. Then, outside of adb shell, (making sure you are in the tools directory of the sdk) execute the following command:
adb shell flash_image recovery recovery-RA-heroc-v1.2.3.img
This should work as long as you have the recovery image in the correct directory.

can i use the rom from modaco? or at least the themes?

No way! This rom is a GSM rom and if it works at all and does not brick your phone then it wont have the right software to make your phone work. A dev has to create a rom specially for the CDMA Hero that has the right drivers.

I am feeling really special, not being able to make this work, but that is the folder that it has been in all this time. I have even downloaded and pushed it several times. Proof:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So I am not sure where I am messing up.
Thanks for all the help and hard work on this BTW!

Meh. Not hard work. Just experience. The hard work is what the rom devs do. And it is difficult at first but once you get it trust me, you get it.Okay let's try this. Go into the command prompt (not adb shell) into the folder where adb and the recovery image is. Try to execute the following command and see if it works.
Code:
adb push recovery-RA-heroc-v1.2.3.img /sdcard/
This will put the recovery image on the sdcard. If this works then we will continue.

[GUIDE] Backing up a phone with broken display

I have seen several of threads asking about how to recover data from a phone that has a broken display.
Backing up a phone with broken display
Prerequisites
Rooted phone with broken display/digitizer/etc. Display is nonfunctional for whatever reason.
ADB for your platform. Downloads for Windows, Mac, and Linux can be found at my dev-host.
Drivers installed (Windows), rules file set up (Linux + Mac). Drivers for windows can be found here. Rules file for Linux can be found here.
Recovery file attached to this post. (twrp.img)
External sdcard with at least 2 GB free space inserted in your broken phone.
openrecoveryscript.txt file attached to this post.
Click to expand...
Click to collapse
Click to expand...
Click to collapse
Backing up your broken device
Extract the ADB zip somewhere convenient.
Move the twrp.img recovery file into the ADB extracted directory.
Move the openrecoveryscript.txt file into the ADB directory.
Open a command prompt / terminal window in the ADB directory.
Windows: Windows Key + R => Type in "cmd" then click "RUN".
Linux: Open a terminal window by selecting it from your applications.
ALL:
Code:
cd /path/to/ADB/directory
Pull the battery from your phone, place it back in and boot into recovery (VolUp + Home + Power).
Connect your phone to your computer
Make sure that the following command returns "XXXXXX recovery" before proceeding to the next step.
Code:
./adb devices
Expected output:
Code:
List of devices attached
XXXXXXX recovery
Now to install TWRP recovery to your device. Type the following commands ( after each line). Linux users: Make sure you prepend each command with "./", as in "./adb ...". ALL Make sure you type the commands in CAREFULLY.
Code:
adb push twrp.img /tmp/twrp.img
adb shell dd if=/tmp/twrp.img of=/dev/block/mmcblk0p18
Wait until the last command above returns an output similar to below before proceeding to the next step:
Code:
12916+0 records in
12916+0 records out
6612992 bytes (6.3MB) copied, 1.094278 seconds, 5.8MB/s
Now pull your phones battery and reboot into recovery once again.
Run the following command to make sure your phone has booted into recovery completely.
Code:
adb devices
Expected output
Code:
List of devices attached
XXXXXXX recovery
Type the following to set up a script that will backup your phone to your external sdcard.
Code:
adb push openrecoveryscript.txt /cache/recovery/openrecoveryscript
Reboot your phone once more. This time, TWRP will begin backing up your ROM.
Wait for the backup to finish. You will know it is finished when you feel your phone reboot once more.
Optionally, you can check the state of your backup by running the following command and reading the last couple lines of it's output.
Code:
adb shell cat /tmp/recovery.log
Click to expand...
Click to collapse

Click to collapse
That's it! Your entire system (/system, /data, /cache, and boot) will be backed up to your external sdcard. Just pop the sdcard in your replacement phone and you're good to go.
Enjoy and donate to the TWRP devs! This would not be possible if TWRP did not use the OpenRecoveryScript scripting engine!

Requesting assisstance with semi-brick issue.

Hello everyone,
I have unlocked my ASUS TF700T and then attempted to TWRP and a custom ROM. Once I did this, I began having issues. It wouldn't boot. I couldn't restore from TWRP backup. I can't seem to write to the system partition for some reason via fastboot but I seem to be able to do this just fine when in CWM or TWRP. Can anyone suggest what I may try from here? I can only get into recovery via VOL DOWN when booting and then selecting the wipe option. Right now I have two major issues. One is that for the life of me, I have never been able to get fastboot to show the actual serial of the device. It has always shown a single question mark. I have gone as far as building a Linux mint box just to get ADP and FASTBOOT drivers to install correctly on a 32-bit machine with USB 2.0. No luck, save result. My second issue is that I am unable to write to the system partition via fastboot. It gives me a remote () error message on fastboot and a could not process the command error in red on my tablet. I will have the exact error message for you shortly but right now I just wanted to get this posted. Any suggestions?
I can't flash the stock blob via fastboot and I can't seem to install a custom ROM via TWRP or CWM. Please advise.
I suspect me not being able to use ADB is my biggest problem. I can't see a serial number when I use fastboot devices. I have tried endlessly to get this resolved and I can't get it to change, AT ALL. I have installed google drivers, 32-bit fresh Linux OS, and plenty of utilities to auto install. No luck. If anyone can help with this, I'd appreciate it.
Here are my issues in a nutshell.
1.) I am unable to boot into recovery directly. I have to go into fastboot and select wipe, it then reboots and starts up in the recovery kernel. TWRP simply executes a command and then restarts and CWM actually boots and allows me to use it.
2.) No matter what I've tried, I have not been able to get the serial number to come up via fastboot. It simply shows a single questionmark. I have tried many solutions for this, but nothing changes.
3.) I am not sure but I believe the bootloader may be the problem. I can currently use fastboot but adb does not recognize the device.
Any assistance would be greatly appreciated. Thank you! I have tried different version of TWRP and clockwork mod but all seem to have the same result. I also attempted to install another custom rom just for good measure and CWM states that
-Tony

Boy oh boy! Mate, your post is one of the most confusing (and confused) posts I have read in a long time. I think you need to go back to the drawing board, forget everything you think you know and start fresh.
Let's clear some of it up:
1) CWM is a recovery (ClockWorkMod), I think you mean your rom is CM (CyanogenMod)
2) When you boot with Volume Down and Power you are booting into the bootloader, you see the bootloader menu and the tablet is in fastboot mode. The bootloader menu consists of 3 icons (if you are on a 4.2 bootloader):
RCK (recovery),
Android (system),
Wipe Data (stay away - it's a small miracle that you are not hard bricked already if you used this)
Are you saying you don't have those three in the BL menu????
RCK should be flashing and pushing Volume Up should boot you into recovery. There is no way to boot directly into it unless your rom has a modified restart menu.
3) adb and fastboot are two different protocols to connect PC and tablet. You use adb when Android is running, you use fastboot when the tablet is in fastboot mode.
Don't know what you tried to get the correct drivers working, but you probably have to go back to square 1 here too. If you use Windows check in Device Manager if your tablet is recognized at all:
Open Device Manager, boot the tablet int the bootloader and connect it via original USB cable to the PC. Do you see any change in Device Manager?
You left out the most important bits:
What bootloader version are you on?
Which version of TWRP?
How did you install TWRP if you don't have fastboot working?
What CM version are you running?

Thanks for the reply. I'll try and be more concise...
Hello,
First of all, I'd like to say thank you. I am all over the place. I will attempt to be more detailed and concise with my wording. Here are my responses below:

I am familiar with the difference. I have not used nor flashed CyanogenMod. I have indeed installed CWM on recovery and can still do so. I just can't boot into recovery without using the dreded WIPE option on my bootloader. Once I use this, it restarts in CWM and I can use it (still fails to install anything on system though.)

I have 2 options for my bootloader when I boot into it, fastboot(USB Icon) and wipe (I think we all know this one.) That's it. This is part of the reason why I can't get to recovery mode without using the WIPE option. (I stayed away from the wipe optoin for weeks until I was convince there was nothing else to try. Once I tried this, I was able to boot into recover with CWM or TWRP. TWRP however ONLY runs some sort of script and then reboots again. CWM allows me to use it. Hope this makes sense. Please let me know if I should clarify further.

I do not. Since I first installed TWRP, ran a TWRP backup and installed the custom 4.4.2 (I believe) rom I have not seen any other options.

I have gone over multiple times but I am willing to start again. I show ASUS Android Device in Device Manager for Windows 8.1 64-bit. (I have tried flashing many times on Windows 7 32-bit and Linux 32-bit both on USB 2.0. No luck, same issues, same results.

I have no clue how to check the bootloader version without getting into Android. My bootloader doesn't seem to show it on the upper left hand side. Do you know how I can get it?
I have tried TWRP 3.2.1.0, TWRP 2.6.3.2, CWM 6.0.4.7 and Phil's CWM based recovery for the TF700. So far, none have been able to flash a custom ROM again nor the stock rom when I use recovery GUI for them. Please advise.
Also, it seems I am able to write to any partition with fastboot except for system. When I write to the system partition my tablet shows red text on the screen that states "the command flash:system failed 0x170003 or something similar. Fastboot shows a failed: (remote() error after trying to write to the partition. Someone told me my boot loader was the problem, but I have no idea how to change it without using the 'staging' or 'flash system commands.'
I'm not sure if this matters but I thought I'd post it. When I run fastboot -w it fails saying that the file system is not supported. When I run fastboot erase userdata or cache. It seems to work without any issues. Here is a sample of the output I get:
Code:

So you can still flash different recoveries via fastboot and enter them from the bootloader. That means you should also be able to use "adb shell" to connect to your recovery (when it is running). What does the recovery do when you try to flash a ROM?
If adb shell to your recovery works, exit it again and run these commands to assess your situation:
adb shell ls -l /dev/block > devblock.txt
adb shell dmesg > dmesg.txt
adb shell hexdump -C /dev/block/mmcblk0p3 -n 64 > mmcblk0p3.txt
and post the resulting files.

Tony - consider yourself lucky since you caught the attention of two of the best people in this business. Do try to get the info _that was asking for.
I am just trying to clarify things:
Do you remember what stock rom you had before you started this adventure?
It sounds as if you were on pre-JB 4.2 stock rom, then flashed some TWRP version and then a KitKat rom?
If you can flash recoveries, you do have fastboot access to the tablet.
@_that, @sbdags Would it be an option for Tony to flash a CWM recovery that "let him use it" and try to flash sbdags' bootloader/TWRP package?
Tony - don't do anything before you get their advice.

I do not recall the stock ROM but I DO KNOW I updated to the latest firmware right after I opened it (Big mistake I know... now.) So, I had no choice but to factory unlcok it with the ASUS TOOL. This was for X-Mas two months ago, so I should be the latest I'd immagine.
I did indeed install a kit kat rom on my first attempt and someone told me I forgot to put the proper bootloader prior and that is why I bricked it. So, I think you are dead on about that but can't confirm.
I do indeed... only problem is that I always get a damn ? for my serial number. I do not believe it has ever shown anything but.... though I didn't check until after I had this problem. I do not recall checking prior to using TWRP to install the kit kat rom zip files.
I will wait. i am very greatful to have help, especially from the top dawgs. xP Cheers!

Your photos show a 9.4.5.x bootloader (and I'm 100% sure about this), which is strange because normally the bootloader is updated together with the stock firmware - so if you updated to the latest firmware, you should also have the latest bootloader (10.6.1.14.x).

[Q] TF700T stuck on Teamwin splash screen

My son tried flashing his TF700T to a custom rom (jellybean 4.4.4)
that appeared to be successfull
however after a few days it rebooted itself and now only boots to the teamwin splash page and stays there
just prior to the teamwin splash page 4 green penguins appear in the top left hand corner of the display.
Let me know what additional information you need to help me diagnose and fix this issue

TWRP seems to hang after trying to mount the data partition. Run this to see if the mount worked:
adb shell mount > mount.txt
If the output file doesn't contain a line for /data, try mounting it manually and see if it contains the usual directories for an Android /data partition (e.g. app, data, local, media, misc, ...):
adb shell mount /data
ls /data > data.txt
If there is file system corruption on /data, we can try repairing or formatting it in the next step - is there any important data on the device that we should try to recover?

OK, then TWRP is having the same problem which explains why it hangs. I've never seen mount hang, but this is most likely due to filesystem corruption.
To recreate the filesystem (this will irrecoverably delete all user data on the device), try this:
Code:
adb shell make_ext4fs -l -16384 -a /data /dev/block/mmcblk0p8
Make sure you get it exactly right - use copy+paste. The command should take a couple of seconds to minutes at most and output a few lines of text.

How can I install a ROM on my phone via ADB from a custom recovery?

My phone's LCD touchscreen is broken and the phone seems stuck in bootloop. I have access to a custom recovery (OrangeFox is installed, but I should be able to `fastboot boot` into any other).
I have read on this reddit post that it should be possible to flash a new ROM, push my computer's ADB public key to it, boot it and use `scrcpy` to control my phone.
However I'm stuck on the first step: how can I flash a new ROM to my phone via command line from OrangeFox or other recoveries?

You can't flash a Custom ROM via ADB, you've to do this via FASTBOOT or Custom Recovery.

Yes, when I said "ADB", I meant the ADB of a Custom Recovery. I can boot into OrangeFox and then `adb shell` into it. I'm wondering how to install a ROM from there.
Installing the ROM from Fastboot would work too, if it's simpler.

TWRP uses dd to flash raw images and tar + gzip to backup/restore userdata partition. It's all done with shell scripting and adb shell is nearly the same.

@peoro The custom rom zip archive is build as OTA update.zip and either has a payload.bin (A/B slots) or *.dat.br compressed images for A-only devices. Both can be unpacked to get the raw images. Those images can be flashed via ADB or via fastboot.

Thank you for the replies. My phone is A-only (it's a Poco X3 Pro).
I just downloaded a new ROM (the latest crDroid 12 for my device) and I could find a number of `.dat.br` files in its zip:
Code:
$ unzip -Z1 crDroidAndroid-12.1-20230106-vayu-v8.12.zip | grep '.dat.br$'
odm.new.dat.br
product.new.dat.br
system.new.dat.br
system_ext.new.dat.br
vendor.new.dat.br
However I'm not sure where or how to flash these files and what other commands I need to use to e.g. format the various partitions or whatever is needed.
OrangeFox offers a `fox` command line tool (I believe it's a fork of TRWP's command). I believe it should help me with all of this, but I'm too much of a noob to know what to do and how.
Would you know where to find a good guide about installing a ROM via command line?
Otherwise could you tell me what commands I'm supposed to run and/or what operations I'm supposed to do?
I know my way around Linux pretty well, can write and read bash, but am a complete noob for anything related to android. Don't even know what the various partitions are, how they map to the contents of the drive and in general how the boot process works...

Yeah. ADB gives me access to a shell on the phone. I can have a shell while the phone is in the Custom Recovery (OrangeFox, currently) and I believe I should be able to flash a new ROM from there. That's what I'm trying to do.
Any way to install a new ROM would work for me: `dd`, the `fox` command line tool, or fastboot.
I'm good with bash, but don't know much at all about Android's internals. But I'd love to find a noob-friendly guide on how to flash to a ROM using whatever tool.

​Which part?
While my phone is running a custom recovery (OrangeFox, TWRP, whatever), that recovery is able to flash a new ROM. It offers a UI to do so. Right? I can't use the UI, but can run anything on the recovery, via the shell opened by ADB.
Am I saying anything wrong?
I have access both to `fastboot` and to the shell of a running custom recovery. But I don't know how to install the ROM (the content of crDroidAndroid-12.1-20230106-vayu-v8.12.zip ) with either tool, without using the custom recovery's UI.

The tool scrcpy installs *.odex compiled Java code on your device. This code isn't executable in any recovery.
Options for flashing your ROM:
– TWRP:
1. Put the raw images of your custom ROM into the ADB folder on your desktop and adb push them to the phone or use MTP to copy them.
2. Then you can use the openrecoveryscript.html (TWRP's commandline tool) to flash images.
TWRP Commandline Guide
</style>CLIENT SIDE/SCRIPTinstall FILENAME : install FILENAME zip file.
twrp.me
– ADB:
1. copy all raw images into ADB folder
2. use adb push to flash the images on your device.
– ABD (adb shell):
1. copy all images via adb push or via MTP to your device
2. enter the device's shell with adb shell
3. You said you are familiar with bash scripting. Do you know the dd command and its syntax?
CAUTION: The command dd overwrites EVERYTHING and without a warning!! Be careful and only use it if you know what you're doing.

Creating RAW images:
You need this tool to convert *.dat.br to raw image.

Flash custom ROM via fastboot:
1. convert the *.dat.br to RAW images.
*.dat.br files​RAW images​partition​odm.new.dat.br​odm.img​odm​product.new.dat.br​product.img​product​system.new.dat.br​system.img​system​system_ext.new.dat.br​system_ext.img​system_ext​vendor.new.dat.br​vendor.img​vendor​
2. Use command

to flash them all.

Using ADB commands or adb shell to run commands in the device's shell (#!/system/bin/sh) doesn't matter. Both passing commands through adb.exe to the adbd on the device. Killing the adbd will kill the connection anywhere.

You must NOT teach me what ADB is and/or how it works.

Options for flashing your ROM:
– TWRP:
1. Put the raw images of your custom ROM into the ADB folder on your desktop and adb push them to the phone or use MTP to copy them.
2. Then you can use the openrecoveryscript.html (TWRP's commandline tool) to flash images.

– ADB:
1. copy all raw images into ADB folder
2. use adb push to flash the images on your device.
– ABD (adb shell):
1. copy all images via adb push or via MTP to your device
2. enter the device's shell with adb shell
3. You said you are familiar with bash scripting. Do you know the dd command and its syntax?
CAUTION: The command dd overwrites EVERYTHING and without a warning!! Be careful and only use it if you know what you're doing.

Thank you a lot for the detailed answer.
I used the TWRP approach as it seems the simpler.
I know `dd` and can read its man, but I'd rather not mess with the phone's partitions and block devices, unless it could result in a different outcome than using the `twrp` tool.
I tried to install two different ROMs (Lineage and crDroid), but neither manages to boot.
I can see that the few visible pixels on the broken LCD are in different colors for the two ROMs (so it did manage to install something), but neither ROM ever reaches a point where the power button turns the monitor on or off: they're both stuck on the bootloader.
What I did is basically this:
Bash:
$ twrp wite cache
$ twrp wipe system
$ twrp install $ROM.zip
$ twrp format data
$ twrp wipe dalvik
$ twrp wipe cache
$ reboot
If that's a correct way to install a ROM, then I guess I have my answer: some of my phone's hardware is broken

Use the adb sideload option to flash your ROM. That's the usual way to install it.
Code:
adb shell twrp sideload # to activate the process on client
adb sideload <ROM_PACKAGE> # to activate the process on host
Flashing starts automatically.

I'm not teaching. I just gave arguments.

Yes, it's the correct way to install. All you need to wipe/format is data.

Seems you already found the solution yourself
How do you know the ROM does not boot? note first boot takes up to 10 minutes.

When the screen broke, I could tell that the ROM didn't work, because:
1. My phone didn't connect to my router. I can tell by looking at the router's log or at internet services that tell me the last time the device was online.
2. If I try to call or send SMS to SIM on the phone, the phone doesn't ring or vibrate.
3. The screen never turns off. Not even when I press the power button.
All those points still hold with the newly flashed ROM too. Of course now it can't connect to anything, but it still doesn't react to incoming calls or to the power button.
I can kinda see from the glitchy colors on the bottom of the broken LCD that the bootloader animation is displayed, but it seems that it's stuck there...
If you have any ideas on how to debug this, I'm very interested.
This is a dump of `dmesg` (from the custom recovery). It shows a bunch of errors, but I can't tell whether any is about real hardware issues.
