You would have to tell me first that it was a 300TG, I could answer that it wasn't good cause the firmwares are different
Sorry bro '
maybe, next time, will be better

have you make a backup by your recovery of your previous stock rom? Hope Yes
So you can just restore your backup on first time, and come back in stock rom for TG
If you are sure, you can test some rom which are compatible with your 300TG

Recovery failure
I am hopeful that someone can point me in the right direction to recover my device. While traveling I attempted to recover back to an earlier backup (twrp made). Everything seemed to go as expected, but then upon reboot, I only received the ASUS screen. I can get into WipeData/Fastboot, but no further.
I attempted to flash the openrecovery-twrp-2.2.2.0-tf300t-ICS.blob as I going to return to stock and then try out the latest Asus rom, but fastbooting openrecovery doesn't allow me to get into recovery - there is no change. Any help would be greatly appreciated!
Next - I pulled the blob from US_epad-user-10.4.2.13.zip and attempted to:
fastboot -i 0x0B05 flash system update.blob
where I renamed the blob to update.blob.
The PC says:
OKAY [141.651s].
writing 'system'
FAILED (remote: ()
finshed. total time: 142.661s
The device reports in red:
Failed to process command flash:system error(0x170003)
Any help would be great!

Thanks for the suggestion to use NVFlash. I didn't get a chance to try that.
Just wanted to share what worked!
1. Grabbed the US_epad....zip from the Asus site.
2. Unzipped twice to get to the blob file.
3. ran: fastboot -i 0x050b flash boot blob
-- this failed with an error 0x170003
4. ran: fastboot -i 0x050b flash recovery blob
-- ran this even though I would have thought it should have been flash boot. Others have suggested that you just
run this program one or more times to achieve success. The good news is that it worked and after:
5. fastboot -i -x0b05 reboot
I now have a fully functioning device again. I hope this helps others.

Hello team, I recovered from possible soft brick like this, following steps by Buster99
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
I'm use blop that corresponding 4.2.1 JB Original Firmware for TF300TL Asus Tranformer Pad, sku:WW

fastboot erase system
fastboot erase recovery
fastboot -w
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system C:\android-sdk\blob
fastboot -i 0x0B05 reboot
:fingers-crossed:
Good luck & be happy by the moment.

[Q] [SOLVED] i think its bricked! any suggestion?

hey guys!
Firstly, i want to install TF300 KitKat 4.4.2 CROMBi-kk my tf300 but my twrp version isnt compatible with this rom. I try to update my twrp to 2.7.0.0 at this topic "http://forum.xda-developers.com/showthread.php?t=2686235"
Secondly, i flashed my recovery to 2.7.0.0 with fastboot but it isn't successfully completed. After that i try to flash official twrp ver. 2.6.3.0 (I guess i updated wrong ver of twrp) and it's accomplished.
After update process, i restarted my tf300 but android doesn't start and teamwin screen came. twrp show my internal memory 0 mb.
Now, i can start my OS through adb with "adb reboot-bootloader " command and select android.
First question. How can fix internal memory problem?
Second question. How can i change twrp ver. with true ver.?
Third question. How can i install new clean ROM?
thanks for your interest.

any help?

You don't get answers probably because it's hard to understand what it is you're asking. I understand English may not be your first tongue, but that's the only means of communication we have here. So try your best English: What exactly is your problem?

Can't update Bootloader to install CyanagenMod

Hey all I'm currently trying to update the bootloader and I've downloaded a few zip files for it but they all get the Status 7 error. I've even downloaded Stock and got that installed but then it gets stuck on the bootup (with the ASUS logo) and then just sits there.

What bootloader you're on (Press power + vol down until bootloader screen appears, look at left upper corner of tab)?
Are you familiar with fastboot? If not: get aquainted.

I know about fastboot and recovery. My bootloader version is US_epad-10.4.4.18-20121012

O.k. Honeybun, that's not the newest.
I would propose to flash newest stock ROM via fastboot.
1. First download from ASUS support site newest stock ROM: ASUS Transformer Pad TF700T Firmware: V10.6.1.14.10 Only for US SKU (Android 4.2.1).
2. Unzip twice; you will get file named blob. Put that in your fastboot folder.
3. Put tab in fastboot mode, connect to pc.
4. Type
Code:
fastboot -i 0x0b05 erase boot
fastboot -i 0x0b05 erase recovery
fastboot -i 0x0b05 erase userdata
fastboot -i 0x0b05 erase system
fastboot -i 0x0b05 reboot [enter]
5. Put tab again in fastboot mode
Code:
fastboot -i 0x0b05 flash staging blob[enter]
fastboot -i 0x0b05 reboot [enter]
6. Blue progression bar will last a long, long time and then reboot itself. Let OS start once.
7. Reboot to bootloader.
8. Flash newest TWRP 2.8.4.0 (plz no CWM) via fastboot and reboot to system.
You should be set now.
Good luck!

I think I love you lol. BTW the only problem left now (which was not one before) is that the gapps package is failing with Status 6. It worked before which is weird cuz the CM version is the same.
First EDIT:
When I just tried to backup I say that it is unable to mount:
/system
/cache
/data
So the scripts in the gapps need to mount the /system so that might be a problem lol
BIG EDIT: I wiped the cache and did a factory reset and now I can mount /system and it now I got the gapps to flash all good. Thank you so much! I love XDA!

Glad that I could have helped you. You would have even more fun if you would install a ROM that supports f2fs.You'd be astonished about the speed gain.

[need help] asus zc520kl [x00hd] any working rom with twrp

Update/Solved:
Currently the only way for people who deleted their OS completely in this phone model X00HD/ZC520KL is to restore the official firmware.
You can ask for a backup recovery folder in XDA Forums ( https://forum.xda-developers.com/zen...help?nocache=1) if you do not have made a backup with people who have the same phone model. You must have TWRP previously installed and bootloader unlocked. Flashing the official firmware via .zip files is not working with twrp, you must restore the folder. After having the files needed, your recovery folder will not appear on the RESTORE section so follow this simple tutorial to make it appear there (https://youtu.be/trlG3ZxwQxI)
This method will bring your phone back to life if you're stuck in TWRP Recovery Mode with "No OS installed". This method is working and it's the only way for you to use your phone again until developers create custom ROM's for this model.

I don't know what do to more, is this ROM link really compatible with my device? I need urgent help.

Thanks for the attention. I already tried tons of ROM's including the official one for this phone. I keep getting Error Number 7. Sometimes when I force an installation editing the uptader-script file it seems everything is working fine, but at the end of the ROM flash process the phone reboots and goes back to TWRP like everything had never happened. I have never seen a successful feedback, just the "Failed" message or a unexpected reboot that goes back to TWRP.
I don't know what do you mean with unlocking bootloader as I have no ROM installed and always I turn ON my phone I go to TWRP automatically. My TWRP version is 3.1.1.

Not working, as I said before, I've already tried to solve this Error. Either 3 things happen: the installation seems to be running good but at some point the device automatically reboots to it's original condition of TWRP (Liniage OS flash and after editing the file to solve Error Number 7 + I get a message saying "Invalid zip format" (Official Asus Firmware flash after editing the file to solve Error Number 7) + I get Error Number 7.

Backup ROM
Hi, I have the same model and I have TWRP as well. I think I can make backup of my ROM an upload it so you can install it on your phone, would that work for you?

Hello @pantarz, yes, give me your backup ROM you have in your phone, it should work on mine. I'm really thankful to see people like this these days. Just need the .zip file for the ROM. Thanks in advance.

Currently the only way for people who deleted their OS completely in this phone model X00HD/ZC520KL is to restore the official firmware.
You can ask for a backup recovery folder in XDA Forums ( https://forum.xda-developers.com/zenfone-4-max/help?nocache=1) if you do not have made a backup.

Hi @ANDROIDMASTER67, @pantarz I also break my phone ZC520KL ( X00HD ). It shows "no os installed" and "error 7" when I try to install a ROM.
Can you please help me fix my phone? If there is a backup that I can get please let me know.
Many thanks in advance.

I've managed to fix it by doing the following:
Copy the original recovery from a firmware package.

choose the option "update using adb"
ensure that adb can locate devices with

I've managed to fix it by doing the following:
Copy the original recovery from a firmware package.
I could find one in the file https://androidfilehost.com/?fid=11050483647474829889, location /Asus_Zenfone_4_Max_ZC520KL_20171225/Firmware/recovery.img
Load default recovery
fastboot flash recovery recovery/original-recovery.img
Restart to bootloader
fastboot reboot bootloader
Load flashboot mode
choose the option "update using adb"
ensure that adb can locate devices with
adb devices
load firmware with
adb sideload UL-ASUS_X00HD-WW-14.2016.1805.374-user.zip ( try download from: https://www.beritahuaja.com/2018/11/download-stock-rom-asus-zenfone-4-max-zc520kl.html )
