This relates to the recommendation in this post.
I followed this guide and got as far as step 25. I have used the "by-name" in the 'dd' 'of' path (instead of "byname").
The device appeared to go into a reboot and froze with the Oppo logo as described in step 26.
Unfortunately fastboot and adb cannot communicate with the device anymore. All I see is a battery charge symbol on the phone when pluged into the PC. Attempting to start the phone normally or in recovery briefly displays the logo and then nothing.
Please help.
you must have made a mistake while following the guide.
it worked for countless others.
check your pm.

Thanks for your help via PM. I'm not sure if my reply PM got through.
The instructions therein seemed to reference files not available in the zipped package, so I was unable to continue.
Trying a few other things I did manage to get some sort of communication via the fastboot command however attempting to unlock or flash twrp returns a permission error.
If I was able to reestablish adb comms I could try the steps again, but I still can't get that working.
Any thoughts?

The word document is outdated but that's what I got from the OEM.
But basically what you have to do to unbrick your device is to plug in your phone to your PC.
Install the Driver in the package. Start the exe file. Read the instructions.txt file. Start flashing.
Why you are not successful with the guide and others are. I can not tell you. I would carefully read the steps and look out for copy/paste errors.
I need help too
Sorry to jump on this but I am in the same situation could you PM me the fix please.
Thanks and respect in advance

So I've been trying to root my thunderbolt for about a week with no success.
At first I used the method here: http://forum.xda-developers.com/showthread.php?t=1005292
It has continually failed on step 2, tried on different computer also. No luck.
I gave up on rooting it for a few days/
Since the first step went through I am downgraded, running 1.03.605. It's got quite a few bugs and when I try to software update from the phone nothing is found. All I really wanted was to get it to the current firmware to fix connectivity bugs but after searching high and low I still have no idea how to/if it is possible.
I assumed I may have to just root it at this point, so I gave the manual root on theMikMik a shot. While setting up my ABD everything runs smooth until I try to enter commands into abd. I get permissions denied, every time. I've tried looking for an answer to this with no luck. Guide I used found here: http://www.themikmik.com/forums/viewtopic.php?f=66&t=256
So my main question, is there any way to get the latest firmware onto my phone without rooting? I've tried downloading an update, naming it update.zip then updating from bootloader with no luck.
If not, what the hell am I doing wrong that is denying me permission in ABD. I've turned anti-virus off, rebooted etc.
assuming adb is properly set up (drivers working), you've checked Debugging and unchecked Fastboot (under setting->apps->dev), plugged the phone into your computer, and typing "adb devices" acknowledges your phone is connected, and you are in fact on the downgrade as you said you were. Make sure PG05IMG.zip is removed from your sdcard then...
Go here and start at step 5: http://forum.xda-developers.com/showthread.php?t=996616
You were getting permission denied errors with those adb commands on mikmik because you are not rooted yet hence the "rooted evo" under requirements.
Edit:
While that may should work, I believe you could start from the beginning with Step 1 using the link I just posted as well. Just don't flash the old firmware (1.0.3.605 that you currently have) after you go through that for any reason (see: http://forum.xda-developers.com/showthread.php?t=1008824).

*Facepalm*
So I tried what you said from that guide, step 5 failed for me. So I tried from the beginning...still failed.
So, I decided to record it and hopefully you can tell me what I'm doing wrong.
Link: http://www.youtube.com/watch?v=o2AFZEIVIio
Figured that'd be a better way to get the help I need with less reading on your part.
Sorry, I was commuting home from work.
According to the output of "adb shell" you're either already rooted or psneuter has already been run since boot. (note the "#" output instead of "$").
There's no reason to run psneuter to gain permroot again. So once you see that pound sign, start from a two steps down where it says "/data/local/busybox md5sum /data/local/misc.img". IOW, skip that particular "/data/local/psneuter" step.
And I would highly recommend that if you are going to copy/paste, only copy one line at a time to prevent errors.
Off to grab dinner. I'll check back later when I can but hopefully you will be good from here on out.
Edit:
I'm perfectly happy with walking you through it (and I believe you should be fine after this post anyway) but if you still wanted to use that easyroot method that you started with you might want to read this if you haven't http://bit.ly/qsvOkN. I didn't use that easyroot method but it looks like if a step fails, people just run it again until it works. /shrug
I like adb and people should know how to use it anyway.
All Further updates will be handled in this other thread
Pre Req:
1) Make sure to install Pantech PC Suite as it will install the correct drivers you WILL need

*Note, I am on 64bit Windows so folders will be different on 32bit windows.
On phone:
go to settings > Applications > Development > turn on USB Debugging
On Computer:
1-Download and install Pantech PC Suite from c724062.r62.cf2.rackcdn.com/PantechPCSuite_1.0.10.3314.exe
2-Launch Pantech PC Suite and update if it asks. When PC Suite is fully updated, plug phone into computer until device is recognized.
3-Download and install Android SDK from developer.android.com/sdk/index.html
4-Start SDK Manager and check the box next to “Android SDK Platform-tools” and install package.
5-Download prestoroot.img from dl.dropbox.com/u/9772722/XDA%20Forums/prestoroot.img and save it to “C:\Program Files (x86)\Android\android-sdk\platform-tools”
6-Download cwm-5.0.2.7-presto.img from tau.shadowchild.nl/files/cwm-5.0.2.7-presto.img.zip and save it to “C:\Program Files (x86)\Android\android-sdk\platform-tools” as well
7-Now open your command line and navigate it to “C:\Program Files (x86)\Android\android-sdk\platform-tools” folder
Run the following command
Code:
adb reboot bootloader
When the bootloader screen shows up on your phone then wait a few seconds to make sure your phone is recognized by the computer then run the following command
Code:
fastboot boot prestoroot.img
After phone reboots itself, shut the phone down and turn it back on again.
Then run the following command
Code:
adb reboot bootloader
When the bootloader screen shows up again then type the following commands
Code:
fastboot flash recovery cwm-5.0.2.7-presto.img
fastboot reboot
8-When the phone boots up this time, download the play.google.com/store/apps/details?id=com.noshufou.android.su superuser app[/URL] from Google Play

FYI,
I've tried uot.dakra.lt UOT Kitchen couple times so far and have been ale to change the font of the device and the color of the glow for overscrolling but my time and other icons up in the status bar disappeared (the "AT&T" still shows up there though). The Backup and Restore in CWM does work nicely though to get me back to before I installed the zip from UOT Kitchen. I'll try 1 mod at a time using UOT kitchen and see which is making the icons and time disappear from my status bar.
EDIT: I did notice one issue with CWM backups. The backup I did today saved the folder name as "1970-02-22.03.14.56". Some reason the date is wrong in the file naming, should have started with "2012-04-13", right?

For those having trouble with a missing driver I followed the below instructions and installed PDAnet (I did so while in fastboot mode so I could see the drivers install) as soon as it installed and the drivers showed installed. I went back and uninstalled pdanet (leaving the needed drivers behind)
hawkwind212 said:
I solved my problem by referencing to part II of the following page:
theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/Describe
Be sure to download two programs PDANet and USBView (which you may not really need but it's a nice little program).
It's suppose to be "stupid easy" to root PANETCH Burst, but who ever said that left out that it's not so easy if you don't have all the proper driver on your computer. Anyway, so soon after the fastboot mode is brought up, you should notice the computer is telling you a new hardware is found. This is when the burst switches from PANTECH's ADB driver to something else, and only way for the command "fastboot boot prestoroot.img" to work is to find the proper driver for the new hardware call "Android" in the device manager. Now you want to install PDANet, and as soon as the installation process begin, it'll find the driver for the device "Android." and install the driver for you. Once the driver is installed, the installation process will tried to install whole bunch other things into your phone, but I really don't think it can install them in fastboot mode, so you'll probably want to terminate the process. Now type command "fastboot devices" and you should see some kind of output telling you that it's recognize the "Android" device. Now, and only now you can follow the rest of "stupid easy" rooting instruction.

they were asking if any of the software we are using would work on a mac. the answer is yes depending on what software you are refering too. the pantech suite (which has been useless to me with the exception it installed the drivers for me) is windows only. I had actually gotten the drivers originally at work by using pda net. The information I gave above is what I came up with after a quick google search. I'm not sure if that or pdanet for mac would have those drivers.

you should download all in one toolkit and use the sideload feature. read the on screen directions as you go through the process and you should have no problems
I also ran into a similar predicament a few days ago. I found adb push to be much easier than sideload. Make sure that your drivers and adb is installed on your PC (I assume Windows). In recovery mode, plug phone into USB and your PC should detect the phone but you won't be able to see phone contents; mine made a connection sound.
Then open a command prompt and type: adb push ROM.zip /data/media/ROM.zip
Rom.zip is the rom file that you want to flash, which should be in the same folder as adb. For the path, I used "/data/media" because the custom recovery defaults to that but you may be able to use "/sdcard" as well.
Then flash the rom using recovery
Hello,
I was asked to forward my problem here so here it goes:
Not a long time ago I bought Asus ME302C FHD 10 and tried to root it. I followed a guide but I can't paste link just now.
Anyhow, the guide told me to flash rooted system image. I did every step correctly except that after i rebooted it, my device got stuck on logo screen, sometimes saying "no command".
I would like to undo that by getting unrooted system image for my device or rather get a working rooted system image. I am not sure about other possibilities as I am not experienced in android rooting or anything related. I do have fastboot up and working.
Thank you a lot in advance.
Edit: I figured out that Asus website has factory system images, however I don't really know which one to use because they all are for different countries and I am not sure what device is mine. Is there a way to check parameters of your device without booting it?
Edit2: I messed with the device more and found out that adb doesn't recognize device, as in, running 'adb devices' nothing gets listed. However, 'fastboot devices' does output my device, not sure where the problem is. Also, firmwares listed on asus website are zipped files and I don't know how to flash them. I tried 'fastboot flash system zippedfile.zip' but it would give me an error.
Solved
After few sleepless nights and loads of browser tabs opened I finally managed to fix my device.
All I needed was to use a different SKU firmware from Asus website. Now I can finally boot it thanks to XDA developers team and their useful information on the forums.

Really desperate here.. :/
Whats happens when you connect the tablet on a PC? First of all , you need check if you can get ADB Conectivity, using Minimal ADB and Fastboot, before that, install Kindle Fire Drivers
https://forum.xda-developers.com/kindle-fire-hdx/general/thor-unlocking-bootloader-firmware-t3463982
After driver installation, download ADB and read how it works (super easy if you pay atention) to check if possible recover your tablet using some comands , read about that and wait for Draxie reponse or Davey126 to get correct instructions.
Here's a case similar to you (stuck in Fastboot) but dont take it as solution, becasue every single brick isnt the same, and you could need other method

You are in a world of hurt. It's possible (likely) the device can be recovered but not without considerable effort and (probably) many failed attempts. Such assistance is beyond what can reasonably be provided via the forums. You can browse through HDX threads to get the gist of what needs to happen. If you are a technology/Android noob it will probably be easier to pick up a refurb at an auction site. Good luck.

If you have fastboot working, your device should be recoverable.
The steps to take depend largely on your definition of "fix it"...
What host platform (i.e. Windows, MacOS, Linux) and variant
are you using BTW? Can you communicate with the device
using the fastboot command?

If it's fixable, it's worth fixing for me.

If I plug my machine into my computer and attempt to access its storage with the android tool that it mentions when you plug it in. I was able to access its storage before this happened, (factory provided cable), (just talking about accessing downloads).
It's bricked!?
How do I use fast boot commands?
And don't I need to make a special cord for it?
I have tons of micro USB to USB cords laying around to.

As I said, if fastboot works, it's fixable (in other words, it's not a brick).
BUT, you'll have to find one of the million guides on how to setup and
use fastboot all by yourself. That's not something I'm willing to spend
time on. Sorry...
As for cables, unless the device is a soft-brick, you don't need a special
cable, but it's preferable to use your factory cable not random junk.
BUT, seeing that you have MacOS, my 1-Click tool _should_ work for you.
Then, all you need to do is click through a web-UI. If you want to do that
instead, you'll have to wait though, because I need to iron out a wrink or
two, and haven't had the time the last week or so...
Do you have the drivers installed ? Its the first step, you need it because ADB program needs recognize a device to work , without that, its useless
Before continue, i reccomend you use windows , the tools provided to get ADB and Unlock bootloader, are simplier for beginners, with linux you need some commands input skills
Second = Install ADB from the link i posted or search it on google "ADB And Minimal Fastboot" dont take more than a seconds
And read please, without your cooperation, i think no one have the time and patience to guide you on a step by step instructions (assuming youre on a tech forum and you need a minimun knowledge before ask/do something)
If you get ADB Connection :aka conect your tablet to your PC using USB Cable ,run ADB (prefer as admin) and this show some device connected (you dont need put some command to get connection)
From my ignorance (Fortunately i do two succesfull bootloader unlocks without brick my devices) i think you screwed the original boot, thats why your tablet starts directly to fastboot mode, if you can get ADB connection, its possible unlock it or reapair, but again, you need know how to input the codes, come back when you post the results about ADB State and read abouthow works ADB before proceed to help you
