[SOLVED]Can't format data...HELP! - HTC One X+

I can't format my device I enter recovery --> advanced wipe check all things and when he comes to wiping data he restart. Is memory dead ? I still have warranty, but custom recovery is on it, and custom ROM, what to do ?
EDIT:
I tried to wipe one by one(internal storage, system, cache, dalvik, and last data) and he only restarts on data when data is trying to be wiped.

reboot into bootloader, and type the following:
fastboot format system
fastboot format userdata
fastboot erase chace
this should make life easier

fastboot format system give me a bunch of commands, same as userdata. Only erase cache did the thing.

Read up I already try that, can't use fastboot erase system or data, only erase cache works. I was at TWRP trying to wipe all but can't when trying to wipe data phone restarts. I successfully erase internal storage, system, cache and dalvik in TWRP.

FIXED:
By Installing cwm recovery, and in cwm he manage to wipe all, and I return to TWRP and did the same thing there, now it's all working again, something was messed up, don't know exactly what, but it's gone now.

Um, your fastboot command shows you are trying to flash twrp recovery. That is not S-OFF. You have to get S-OFF first.
go to this website and download the linux one. get s-off and then flash twrp through fastboot

cannot install twrp and stock recovery deleted- help needed please

Need some help please with something that has gone wrong with my first attempt to alter Android. I wanted to install a custom recovery, root the phone and take it from there.
I have a Moto e 1st edition, xt1021, system info given below.
I unlocked the boot loader, installed Minimal ADB Fastboot 1.4.3, downloaded the latest TWRP image 3.3.1.-condor for the Moto e from the TWRP website.
I used flashboot flash recovery initially to install the TWRP image, which failed, but has wiped the stock recovery. I cannot boot into recovery or do a factory reset.
The phone will boot normally. If I try a factory reset, it boots normally. If I boot into recovery, I get the Android image on his back with a red triangle, and “no command”. If I go into system recovery from here, and try both 'update by adb sideload' or 'update from sd card', both fail.
I have tried flashboot boot recovery using a stock recovery, but the phone is stuck on the initial Moto logo.
I have also tried to install an earlier TWRP recovery, 2.7.1-condor and CWM 6.o.4.7 falcon but this has failed to install also.
I have now reached the limit of my abilities – any help much appreciated, but please spell out in words of one syllable if possible.

Android SDK Platform-Tools is a component for the Android SDK.

You need to update your adb/fastboot. Download the latest platform tools from the link above.
That seems a bit odd since I just downloaded it 2 days ago from Google! Could have got an old link but I doubt it...
Didn't work unfortunately!
I downloaded the zip file from the link, unzipped with 7zip and got "platform-tools_r30.0.5-windows". Within there is a folder named Platform Tools.. I held shift and right clicked on the white space in that folder and opened a powershell.. Ran this:

PS C:\Users\CSW\Downloads\platform-tools_r30.0.5-windows\platform-tools> fastboot reboot fastboot

And received the same help menu and no change on my phone.. Same result.

The trick for our SOFIA is to execute the ADB command while the phone is POWERED ON (System booted up like normal - like when use the phone, make calls, etc) and NOT in fastboot/bootloader mode:
Enable USB Debugging in developer options on phone
Connect USB cable
Answer confirmation/security prompts on phone and PC
Type "adb reboot fastboot" at ADB CLI
FASTBOOTD will now appear in red letters at the top - you are in FASTBOOTD mode
Hope this helps!

[Question] Fastboot oem unlock failed to unlock bootloader

Hi there,
The device is
- usb debugging;
- oem unlock in Developer options;
both enabled.
adb devices recognized device.
In fastboot mode,
Code:
fastboot oem unlock
returned
Code:
OKAY [ 0.007s]
Finished. Total time: 0.019s
And the device rebooted from fastboot mode into Twrp recovery.
After the device rebooted into fastboot mode, fastboot oem device-info showed
Code:
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Device is_verified: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) console_locked: 1
(bootloader) exec_console_unconsole: 0
OKAY [ 0.072s]
Finished. Total time: 0.072s
Bootloader remained unlocked.
In addition, fastboot flashing unlock produced
Code:
FAILED (remote: 'unknown command')
fastboot: error: Command failed
How to unlock the bootloader of this device?
May you need any further information, please do not hesitate to contact me.
Thanks in advance.
Hi there,
after fastboot oem unlock, the device booted into recovery.
And fastboot erase cache , it returns
******** Did you mean to fastboot format this ext4 partition?
Erasing 'cache' FAILED (remote: 'device is locked. Cannot erase')
The same result was produced after fastboot erase recovery.
How to solve it?
Thanks.
Wen
PS: The device was detected following fastboot devices
sounds like you did not unlock bootloader right way. most devices need another predecessor step: oem unlocking in developer options.
Btw do not use fastboot erase command at all, do not follow any tutorial that suggest this.

Thanks for your reply.
Could you please specify the reason that "fastboot erase" commands should not be used?
fastboot 'erase' is dangerous command. it will erase the entire partition, which is not what you want. for example erasing recovery (like you tried) will brick your device (what was the intention behind?)
'erase' is useless intermediate step in most cases. for example when fastboot 'flash' recovery, the recovery partition will be sequentially overwritten from given file anyway. you can just skip erase it doesn't matter in such case.
partitions containing mountable file system must formatted like this (unlocked bootloader required)
Code:
fastboot format:ext4 cache
fastboot format:f2fs userdata
without formatting, the phone cannot mount the partition and will brick (few phones are smart enough to complete the formatting step automatically, though)

Hi, thank you for your replies, sorry for my belated responsiveness, owing to the recent recovery from (severe) covid symptoms.
I once used "fastboot erase recovery" because the device was stuck on the logo of newly installed recovery, and had no other means to resolve it.
So do you mean that the right way to format cache, userdata or system partitions should include the format of the partition (ex. ext4, f2fs) in adb commands fastboot format:ext4 cache, fastboot format:f2fs userdata?
If so, will the simple command fastboot erase userdata do the same thing, given that userdata is located in one simple partition, ex. mmcblk0p43?
Both fastboot format:ext4 system and fastboot erase system will wipe out the same partition (say, mmcblk0p19 where the system partition is lcoated)?
What is the function to include disk format (ext4 or f2fs) in adb commands?

Yes, but there is a difference.
erase will delete entire partition.
format will only format file system.
including file system type is optional.

What is the difference between "delete entire partition" and "format file system"?

I assume once in your life you have created partition table with one or more partitions on single disk, be it windows or linux. every partition must formatted to receive a valid file system (NTFS FAT32 ext4 swap etc.) otherwise the raw partition is just unused inaccessable disk space.
"format file system" is when you format existing partition to valid file system type, in order to make it mountable
Ok thanks.
What else do "delete entire partition" and "format file system" do, apart from wiping out the data?
So the difference between two is that one would be mountable afterwards, the other not?
right. erase will just write 00 00 00 00 00 00 00 00 zeros on whole partition (invalid/empty disk space)
format will create a valid file system, so partition becomes useable.

to be nitpicky: partitions aren't mounted. file systems are.
Thanks.
So fastboot erase userdata,
fastboot erase system,
fastboot erase cache,
fastboot erase recovery
will overwrite their respective partitions (userdata, system, cache, recovery) by 00 00 00 00?
And by format like factory-reset, the data remain intact on the file system?
What are the relations between file systems and partitions?
It's good to be nitpicky in the context.
Here, by "mountable" you mean "to be able to read and write" (the file systems)?
Thanks in advance.
if you erase cache partition, the phone will no longer boot.

on formatting, no data remains intact, new (empty) file system is written to partition.

It is contrary to my experience.
After running fastboot erase cache, the device safely rebooted.
Here, "intact" means not overwritten by new data.
your bootloader is locked, therefore any harmful cmd (such as flash, erase, format) is forbidden and has no effect. (btw phone gave you warning you mixed up cmds format with erase)
Code:
fastboot erase cache
******** Did you mean to fastboot format this ext4 partition?
Erasing 'cache'
FAILED (remote: 'device is locked. Cannot erase')
I said on formatting, no data remains (nothing survives) because it is overwritten by new file system.
(Maybe on quick format some data may survive, but not provided by file system and therefore invisible/non existent, like free disk space.)
I was talking about fastboot erase cache that worked on another bootloader-free device.
then you are lucky your phone...

(few phones are smart enough to complete the formatting step automatically, though)

unexpected behaviour. did you try fastboot flashing unlock as well?
Yes, but there is a difference.
erase will delete entire partition.
format will only format file system.
including file system type is optional.

fastboot flashing unlock produced the following error.
What brand/device model/android version you are trying to unlock?
Code:
adb shell
$ getprop ro.build.fingerprint
$ getprop sys.get_unlock_ability
$ getprop ro.oem_unlock_supported
$ getprop ro.oem_unlock_allowed
