Before you fix your recovery you will need HTC Sync Software http://www.htc.com/www/help/htc-one-x/#download
And ADB installed from the SDK here http://developer.android.com/sdk/index.html
Once you load the SDK Manager download the Android SDK platform tools. Then download the proper recovery Image that has official support for the AT&T One X from here http://teamw.in/project/twrp2/99
Go to the folder you installed the SDK tools to If your on Windows 7 x64 and installed it using the default paths it will be located here C:\Program Files (x86)\Android\android-sdk\platform-tools when at that folder move the recovery image file in to that folder then hold shift and right click in the folder select open command window here.
Now get your phone back into the bootloader select fastboot and connect it to your pc when your phones bootloader says fastboot usb its connected and ready to fix.
type fastboot flash recovery openrecovery-twrp-2.1.8.1-evita.img
that will update your recovery to TWRP which is much better than CWM. From there you can select reboot into recovery from the bootloader TWRP will load up you can Wipe /system /cache then mount your phone to your PC and upload any ROM you want. I recommend AOKP or CleanROM and flash away.
People really need to start searching before they post this is somewhere around the 20th post I've seen like this in the last couple days. All want help unbricking and people have posted guides on how to unbrick. Also there are many posts about how CWM for the HOX is highly unstable.

[Q] asus transformer tf700 wont start up

please help it says it has no os installed when i go to recovery mode is there a way i can install it with an sd card? where can i download it from please help
Friend - how are we supposed to help if you give us NO information????
How did you get yourself into this pickle?
I used the coffee grounds from my afternoon latte to guess this:
You have a custom recovery installed and can boot into it - which one?
You wiped from recovery and included your system partition. Not a good idea if you're not prepared to flash the rom right afterwards....
You ran some custom rom - which one?
What bootloader do you have installed?
Fastboot access working or ADB in recovery?
If you're really lucky all you have to do is copy your favorite custom rom on a fat32 formatted microSD, stick it in the tablet, boot to recovery and flash the rom.
That is if you have the correct bootloader and recovery installed, but how would I know?

[Q] to root or not to root

Hello,
1st.: while starting this new thread, I looked through the automaticly generated similar threads and found non that was suiting my problem.
Last night I unlocked the bootloader of my wifes Xperia L (C2105) and got stuck into an boot loop. After this I had the need to flash an original rom (4.1.2). This results in an total wipe of the phone :crying:
Now the phone has an unlocked bootloader and an old Android Version. I want to install the pacman rom 4.4.4. I know i have to use cwm or twrp to do this, but do I need to root the device?
I'm a little bit confused. I thought installing the *.img-File from TWRP, with the folloing command, will get me the recovery option an with this option
Code:
c:\fastboot\Fastboot.exe flash boot C:\fastboot\openrecovery-twrp-2.8.4.0-taoshan.img
Can anyone help me out?
My wife is not upset, but with the boot loop from last night in my mind, I'm quit unsure what to do next.
many thanks in advanced
Felix
you need to root the device and use flashtool by androxyde(Easier and user friendly), first download the rom and put it in internal/external memory and then install thunderzap 4.12 by select bootkk.img and install it in fastboot mode in flashtool, now enter the recovery go into wipe and format options and choose clean to install a new ROM and then flash the pac rom and reboot
Root isn't necessary.
Download PAC ROM, Take boot.img inside the zip.
Flash boot.img via fastboot.
Boot into recovery, wipe data / factory reset.
Flash ROM and GApps.
That's it
NOP, you dont need to root to install a custom rom

you can download the rom, extract it and keep, boot.img file, in fastboot folder, and also keep the downloaded rom zip file in sd card for later use.
than you can use use fastboot commands to flash those boot.img which will install the recovery into your phone, than .
use reboot command in fastboot, it will reboot your phone, take out your cable, using volume up key go to recovery,
there clear all the cache and delvik cache file, then, install your custom rom by selecting from your sd card, it will take a bit of time for first time, so don't worry,
than you are done,

Not booting to recovery

what i did -->
1. Unlock bootloader
2. Flash cwm via "fastboot flash recovery recovery.zip"
3. Boot to recovery
4. Factory reset
5. Flash cm zip from sd card.
what i got -->
1. "E:Can't open /sdcard/cm.zip
(bad)
Installation aborted."
Then -->
1. Rebooted, copied again, booted to bootloader
2. selected recovery
Now -->
1. shows the android mascot with its lid open and "No command"
2. no cwm (where did it go ?!?!)
Everytime i flash recovery, it boots the first time (till the time I've not rebooted after flashing recovery) and still won't flash my zip file, and then the recovery won't show.
EDIT (FIXED)
WHAT WENT WRONG...
1. Was using CWM (When i was last active in android flashing, twrp was just another custom recovery, cwm was needed for cm)
2. When i did use TWRP, it was an older version, and did not work (did not even boot to recover, in fact)
3. When i did get twrp working, i used a bad cm.zip file (corrupted)

first mistake here is u used Flash cwm via "fastboot flash recovery recovery.zip" which is wrong u need to use .img after recovery but not zip so try once again and flash latest twrp as cwm support is ended

Thanks for the promt reply mate. Actually it was recovery. IMG only, not zip, i typed it wrong here otherwise the recovery wouldn't have loaded at all, as mentioned earlier. Moreover, I did try flashing twrp, but using twrp, I can't even get recovery to boot once (which does happen on cwm 6.0.4.7)
P.S - can it anyhow be related to bootloader ? I am on stock Lollipop. And device is dual sim (xt1033)

If u r on stock lollipop then u boot loader is already upgraded and its good for twrp recovery can u try flashing twrp v 2.8.6.0 and check it out using adb if it is already rooted then try flashing by flashify and let me know

Ok did that. When it booted to cwm (which is all i can manage to boot to, if at all) i selected root phone option. But it didn't root actually. Then i rooted successfully using cf auto root. Then used flashify to flash twrp image, and now when i select recovery from bootloader, it boots normally, not even showing the "no command" screen. (And yea, I'm pressing vol up to select, not power)
Update -- Ok flashed 2.8.6.0 and now boots to revovery (even after a restart) but still can't flash cm. Something pops on screen for a fraction of screen and then recovery reboots. It says "no md5 file found". Any chance of zip being corrupt ?
Update 2 -- Now my internal memory has stopped working :/ can't even take a screenshot, nor a photo. says memory full. Doesn't even copy file to memory when connected to pc. Although in recovery mode (twrp) , with usb mounted, it does copy.

weird did u flash normal recovery or gpe recovery ? U have to flash normal recovery and one more thing are u sure that its going into cwm recovery ?
May be the ROM is corrupted buddy download again and flash or try other Roms
Haha. After a hell lot of effort, i did get TWRP installed, and after breaking my head on why cm nightly won't install, i downloaded another one, and it installed fine. Now rocking CM 12.1 (4th device which I'm using on CM, and yet never had so much trouble getting it running..)

Alternative Fix for Bootloop + TWRP Hang/Reboot

Symptoms: Tablet hangs on Asus logo or continuously reboots to the Asus logo, never to Android. When you try to enter TWRP recovery, it hangs on the TeamWin logo and then attempts to reboot Android, going back to the bootloop.
I wanted to find a different method to solve this issue without having to erase all partitions manually. This is what worked for me.
You will lose all data on the tab regardless of how you fix it.
You'll need these files (and the Android SDK, or at least fastboot)
CWM recovery (Cyanogenmod) http://www.mediafire.com/file/gpkvpnriqevwdfu/cm-11-20160815-NIGHTLY-tf700t-recovery.img md5: f6a3693d42aae4f412c4c8348f7ff185
Zombi-X 6.0 ROM from here https://forum.xda-developers.com/showpost.php?p=65968239&postcount=3719
OpanGAPPs 6.0 pico from here http://opengapps.org/
SuperSU from here https://download.chainfire.eu/1113/SuperSU/UPDATE-SuperSU-v2.82-20170528234214.zip
Follow steps in Post#2
Put the recovery img in your fastboot folder. The ROM, gapps, and SuperSU go on your external microSD.
Flash the recovery with fastboot-don't forget the .img at the end
>fastboot flash recovery cm-11-20160815-NIGHTLY-tf700t-recovery.img
You should see a blue progress bar on the tab while writing. When it's finished reboot to recovery.
Format "/data and /data/media"
Flash the ROM, SUperSU and gapps.
Wipe cache
Reboot. CWM will ask to reinstall su on exit, answer No
Once the ROM is up and running, you can flash whatever recovery and ROM you prefer.
