[Q] Can't Access Fastboot - Asus Eee Pad Transformer Prime

Hey folks,
First time poster here, but have been following this awesome community for a few months now. So with that being said, I've landed myself in deeper water then I had hoped to see on my first foray into the world of tinkering on my tablet. I feel I should also disclose my epic newb moment, where in I ran headlong off the cliff with making proper (any) backups
I've been doing a lot of reading the last couple days to try and solve the issue, found lots of radical advice, but sadly haven't managed to get myself any further ahead. I was hoping that with a little list of what the TF201 is doing & what I've tried since, that you folks might be able to shed some light on what I've done and what I can try.
The Problem:
I've got a TF201, unlocked, TWRP 2.6.3.0. ADB access from command prompt. Sadly that's all I've got at this time (No OS, No fastboot). I cannot seem to install an OS now, but can still push files over to the tablet/view them. As far as I can tell, I'm have Brick 1a from this post: http://forum.xda-developers.com/showthread.php?t=1514088 . It references (CWM), so Im not sure these steps are applicable (My understanding is this is a recovery manager though I could be mistaken).
I've also explored:

Etc.
So my question is, is there a process I can follow from TWRP to get me back to fastboot access? OR am I looking at the problem from the wrong angle? Any advice or suggestions would be appreciated. Apoligies in advance if this is addressed elsewhere! If there is any additional info I can provide please let me know.

Still have fastboot access, however now can't access recovery when I fastboot devices my device now shows up as ??????????? Fastboot, rather then the letters/numbers it used to show. Feeling like I've slid her a little deeper into the mud. Also a lot of "unrecoverable boot error 0x00000000"

Get yourself back into fastboot. I'm guessing you got there by typing adb reboot fastboot from in TWRP.
You will need to make sure your fastboot and adb exes are compatible so try these. http://flumpster.lolcakes.com/android/adb-fastboot.zip
I know they are old but I also know they worked.
Next you would have to make sure you had the correct drivers installed. I've always used these. http://www.koushikdutta.com/post/universal-adb-driver
Now follow the instructions here http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
But where he says to get the TF300 firmware etc get the TF201 instead.
EDIT : Are you also sure you are in fastboot and not in APX mode. Explain how you got to fastboot please.

Thanks for the reply flumpster, I was actually working my way through that when you posted. So now I can get into fastboot, however I have no OS installed currently. I'll keep poking at it, I feel progress is being made
EDIT
I am powering down and holding volume down. I may have a terminology issue here, but that is what I believed was fastboot.
EDIT 2
Also confirmed adb and fastboot are working, and confirmed Im using the same driver you recomended. I am now sitting with 4 options, RCK, Android, USB & Wipe Data.

With much fandangling, have got myself back to a bootable environment running the rom located here: http://forum.xda-developers.com/showthread.php?t=2147895
From what I gather I should get my backups made asap, NVflash seems to be the most commonly mentioned, but am getting an error with step 1 in wheelies. However, its another issue so I shall consider this thread case closed and go back to reading. Thanks again for the help!

[Q] One Click Bootloop + Trackball Issue

Okay, so I've seen these issues dealt with separately, but never in conjunction. Unfortunately, I am having both in conjunction.
Starting with a fresh Droid Eris, I used a one-click root to allow superuser permissions.
From there, I flashed CM7. Along with many other users, I ran into the issue where I had no data or voice signal.
I'll let you know here, that I've wiped EVERY time I did anything. This is NOT a wipe issue.
I flashed the newest radio... No luck. So, I went through clockwork's recovery and reverted back to the original 2.1 ROM. Still no luck on the signal issue. At this point, I decided to reflash CM7 and try to deal with the issue through ADB.
This is where things went wrong. The load for CM7 corrupted (I'm assuming) and gave me a nice case of Bootloop. Thinking everything was fine, (Assuming I'd do a battery pull and just go back to 2.1) I booted into the original Android recovery and NOW the damn track ball will no longer make selections. It will scroll, but not select.
Here's my question: Seeing as I can not boot fully to allow usb debugging, and I can not recover through Android (Thank you, trackball), is there ANY way to reflash the original RUU through ADB?
Thus far, I can't get passed the obvious "This device is not ready," prompt.
Any help is greatly appreciated.
FYI, adb is available when the custom recovery is booted.
what that means is that with the recovery booted you can:
1) drop a smallish (say, less than 100 MB) ROM file into /cache (e.g. "adb push")
2) create an Android command file (/cache/recovery/command) with a single line that points at the ROM file as an update
3) do a "adb shell reboot recovery"
This will cause the subsequent boot to the recovery to automatically install the ROM file you dropped in cache.
Voila. No trackball needed.
The syntax for the command file (/cache/recovery/command) will be a single line:
--update_package=CACHE:your_ROM_file_name_goes_here.zip
See this post for an expanded explanation.
cheers
[ Edit ]
Note that the above is a thumbnail sketch which requires you to fill in the blanks. For instance, wiping /data and /cache and flashing packages after the main ROM. Cumbersome, but you only need to do it once. Once you have a rooted ROM installed, you should flash a trackball-free version of the recovery so you don't need this method for every ROM you install. Instructions for that (using "flash_image" via adb) can be found elsewhere.
Scott,
Whoa! You got a lot going on there...
Okay, I don't have all of the answers here for you, but I know enough to ask a few questions that we'll need a clarification on.
1. Can you tell us your HBOOT version and whether its S-ON or S-OFF?
2. You mentioned that you've used ClockworkMod (not good , but maybe not terrible)...you also have mentioned using/having Amon_RA custom recovery. Which custom recovery do you have currently installed and can you boot into said recovery?
3. By the way, I think the voice/data signal thing is fixable--it sounds familiar to me, but I don't know the answer right off-hand and this is not your primary issue at the moment.
4. You should be able to run the RUU to restore 2.1 back to your phone. It doesn't require a working custom recovery running and/or adb. Although you might simply be asking if you can flash a ROM through adb, then the answer is yes, you can. Although you will need custom recovery running to make sure its adb server is running and that, of course, require USB connectivity (alluding to your "This device is not ready." message).
5. Usually, installing HTC Sync will install the USB drivers necessary for you to use adb. If that doesn't work for you, PM me with your email address and I'll send you about 10MBs worth of USB drivers I've collected over the last year that might help you with this issue.
6. Lastly, there is a version of Amon_RA's custom recovery available that does not require the use of the trackball. You're not really in a position to flash/install that at this point unless you have the S-OFF engineering bootloader.
I'll hold-off with additional info pending your responses to the above.
Cheers!

[GUIDE] The DO's and DON'T's with your unlocked Prime

Hey guys,
apart from my Un-Bricking-Thread I wanted to start a Thread dealing with how to prevent a brick in the first place.
--- Already bricked your Prime? Read on here, maybe you can recover it ---
In the last days I learned quite a few things about the TFP, its CWM and how to work with it. I also hard bricked my Prime so I certainly know what I am talking about
Unfortunately ASUS didn't fully unlock our Bootloader. We still can't use NVFLASH for low level flashs.
This also means that we can't recover some things we could with NVFLASH access (like a broken bootloader).
So lets start with the things you better not do:
DON'T
Once you unlocked the prime and installed CWM, do NOT try to install a super blob from ASUS (that is a blob file from one of the 'full' updates from their site)
It seems that doing so totally bricks your Prime with no chance of recovery... (happened at least twice so far)
Don't flash kernels like you used to flash (with write_raw_image to /boot). This does not work on the Prime. More on how to do it later.
Don't rely on your newly created ROM to work, ALWAYS have a backup of a working ROM on your sdcard (or a zip of a working ROM)
Currently we can't mount the USB-Storage from inside CWM, so transferring files to the Prime while being in recovery is not as easy for many not so advanced users.
Always make sure you have all files you need before rebooting to recovery.
DO
Kernel flashing: There seem to be two methods on how to flash a new kernel. One is safer but needs a bit more work, and the other is rather unsafe but okay when you (or the ROM dev) know what needs to be done.
Flash your boot.img via fastboot. This is usually rather safe (as safe as fastboot can be) but needs you to have a working fastboot environment. Update: It seems kernel flashing via fastboot does not work at all. Fastboot doesn't give you an error but it doesn't update the kernel either...
Flash your kernel via the /staging partition. In order to use this method you first need to pack your boot.img into a blob file.
Then you need put the data from the blob file to the /staging partition.
Once you reboot the kernel gets automatically installed.
Please be aware that you can flash almost everything like this, even the bootloader.
So if you screw up packing the blob file, you could easily brick your Prime.
The advantage of this method is that the user doesn't need to do anything, but you really need to take care of what you are doing.
Also make sure that the /staging partition is ALWAYS unmounted before flashing anything to it. Otherwise this will result in a Brick 3.
Always make a backup of your current ROM before flashing anything else. As stated earlier, we currently have no access to the sdcard in recovery, so transferring files to Prime is not as easy in recovery mode.
So I hope I can find some more topics in the future, but for now that's it

Thanks, thanks, bump, and thanks again! Due to the current state of our device's development (especially with an early build of CWM), misinformation floating around, etc. this is invaluable! Now I know what "staging" is and what its use is. Well done - keep up the great work

Use custom ROMs. We currently don't really know if it ALWAYS bricks your Prime. We just know that two updates bricked two primes

Yea I am just kidding. I knoweth better plus I like custom roms (and I am very flash happy)

Will be possible to use NVFLASH anytime? Have we to look for a dev or is Asus that must upgrade its apk?
Thanks Diamondback for making this. This needs to become a sticky immediately. To many people are blindly unlocking then get mad when they find out they can't do OTA updates. Or people installing CMW without even unlocking and blaming others issues on that when they found out device should've been unlocked first..lmfao
Unlock tool release=operation sabotage for those who don't know any better or ignorant or lazy to research first. QnA section had several people with semi or hard bricked primes. Primes are dying off left n right..lol

So you download their software, run it to completely void your warranty (they've already denied support on one unrelated hardware issues that I know of), and you STILL don't have full access?
WTF!?!?!!?
Not being able to use NVFlash has completely put me off, for me NVFlash was the ultimate aim for unlocking the bootloader ... pretty **** !
(unhappy smiley)
Diamondback, I'm so sorry to hear that you bricked your Prime! Any luck getting unbricked yet?
Thank you so much for posting this invaluable guide. You are generous beyond words, to go to this effort to save other users from the lessons you had to learn the hard way. There aren't enough thanks in the world.
If we can at least ATM use fastboot that's a good thing. A good thing for fastboot is you can first do-
fastboot boot boot.img and it will boot the kernel the first time, basically so you can test it before it writes the .img
then you can fastboot flash boot.img to write the image. It'll work for now, sucks that any non-dev who just wants to flash a kernel has to set up fastboot
Edit- girluvsdroid- just saw you were in wilmington- me too.
This was very helpful.
BUMP!
Reading is fundamental! Lol I don't know how many times I've just glanced over post, just to get the newest firmware, and kernals, just to end up on the verg of a bricked device. Thanks.
What ?

Yes. fastboot boot does not work at all.And we also found out that kernel flashing via fastboot does not work either.
You have to flash your kernels via a custom made blob ;-)

Prime Stuck in CWM boot loop hell.
I have a Prime that is stuck in a CWM Recovery boot loop.
Brick 1a
All thanks (sincerely) to Viperboy and his ViperMOD PrimeTime 4.5, I had my Prime rooted, boot loader unlocked and loaded with ClockworkMOD Recovery 5.5.0.4.
I used CWM to create a backup, wipe the data/factory, cache partition and Dalvik cache, rebooted the system (from CWM menu) just to verify that the unit was really wiped back to setup, powered down the unit, rebooted into CWM Recovery (using Power while holding Vol.Down, wait for small/white text, Vol.Up) and Restored using the previously created Backup.
I rebooted Android from CWM menu and my Prime was restored.
Everything was great, but not for long.
The next time that I booted into CWM recovery I selected “Reboot System Now”.
It went dark, displayed the ASUS splash screen, went dark and went back into CWM.
I am stuck in that loop.
I have tried all the suggested fixes I can find but all methods are useless because:
1. I can’t acquire an ADB connection because Windows doesn’t identify the bricked Prime correctly and won’t install the USB drivers. Device Manager sees “Full Android as Emulator”.
2. I can’t boot into the boot loader to use Fastboot because I never see the option to choose it. It boots or reboots directly into CWM after “Booting Recovery Kernel Image”, ever while holding the Vol.Down button.
I have repeatedly tried installing and uninstalling the drivers by installing and uninstalling the Asus Sync and Asus Android USB Drivers. I have repeatedly tried to install the drivers via the Device Manager. No good. I’ve installed and uninstalled Android SDK Tools repeatedly.
Is there a way out of this? I hope I'm not efed.
Thank you in advance for any help.

Universal Naked Driver works great!
Ok, you saved me and my precious.
Your drivers were exactly what I needed.
After installing them in Device manager I was able to achieve a “ASUS Android Composite ADB Interface” connection.
Following the “How to Unbrick your Transformer Prime (or not)”, Option 1a and restoring I’m up and running.
Thank you!
Then, I deliberately caused the boot looping condition again to see if I could figure out how I got there.
There is an app that I think comes preinstalled on the Prime called ”Transformer Recovery Boot”. The icon is labeled "Recovery". This is the app that took me into the Brick 1a the first time and I duplicated it the next time I used it.
Then I was able to ADB my way back to civilization, again.
Thought I’d pass that on incase it helps to determine why the unlocked Prime seems to be so susceptible to bricking.
Again, Thank You!

Will pay $$$ for help with TF201

So, I have made a major boo boo when it comes to rooting devices and flashing custom ROMs; normally I am not a n00b when it comes to this, but I think I gone done something wrong this time. I have checked Diamondbacks thread as well as many other and have a whole slew of tools downloaded now and I cannot seem to get past the splash screen. ADB recognizes my device as well as Windows in Fastboot mode, just can't seem to figure out how to flash the stock ROM back on this device. I would be willing to donate money to the cause as this has cause me much undue frustration. If you are up and willing to the task, please PM me or even call my cell to walk me through this. Couldn't find XDA's chat, all I am asking is that someone have a heart and help a fellow techie out.

Not sure what recovery you have now but I suggest you go here >>
http://forum.xda-developers.com/showthread.php?t=1615990 and install twrp recovery through the fastboot method. Boot into trwp recovery. After that, download the nvflash files from here http://forum.xda-developers.com/showthread.php?t=1774352
Not saying you should use nvflash at this point but the file also contains a known good adb.exe file. Unzip the file and while in that directory press and hold the shift button while right clicking the mouse. This will bring up a menu select open command prompt here.
Put your rom into the same folder as the adb.exe then in the comand window type adb push /name of your rom.zip /sdcard/ if this doesn't work use /sdcard/media At this point you should be able to install the rom. As for the rom, a good starting point would be androwook rom since it seems to install quite easily (do not unzip). Also when you are performing commands in either fastboot or adb, it is best to copy (control c) from the webpage then in the command window right click and paste, this eliminates errors. Having the files you are flashing in the same directory of fastboot or adb eliminates the need to type pathways, this is where many people run into issues, 1 wrong letter make everything not work....
Thanks Gage_Hero, the TWRP tutorial was just what I needed in getting a custom ROM flashed to the device; however, my next question is, if I did not create a backup of the stock ROM like I should have, will I ever be able to get back to it should I need to update the OS or for any other reason? From what I have read, Asus stock ROMs have a unique ID to every device, making it virtually impossible to use someone else's backup for flashing. Much appreciated for any information you can provide.

Most people don't have a stock backup since once you are unlocked, trying to install the ota update can make the tablet inoperable. So basically when Asus updates the software then the developers here pick up the stock rom and enhance it. This goes anywhere from the base stock rom with root up to taking the rom and customizing it with options, kernel changes and such. The only thing I will say about changing kernels is only use kernels that were developed for the particular rom or you will have trouble. Kind of like taking a Ford motor and trying to mate it to a chevy transmission.
If you do change roms, make sure you wipe cache, dalvik and do the factory reset from within twrp. When you become comfortable, I suggest looking at the NVflash thread in the dev section. This will provide you with a bit of assurance that you can recovery from most software brick situations. Read over the instructions a few times before you go a head and take some time to read through the thread so you know what could potentially go wrong. It really isn't that difficult to do but you should be well informaed before proceding. If you need anything else don't hesitate to ask
Another thing that i find helpful, keep a stock rom in your sdcard. When i semi-bricked my 201, i was able to flash the stock rom using CWM, then do a factory reset. Once back to factory, i was able to boot and start over again.

Possible Unbrick Solution for Unrecoverable Bootloader & Wrong TWRP Flashes.

I found the following post while doing my daily read thru all the other forums and some people are saying that it has rescued them from wrong TWRP flash and Unrecoverable Bootloader errors.
I would try to do all the other methods available first but if you are completely bricked then you have nothing to lose.

Flumpster, I was going to start a separate thread to take my brick issues out of your dev thread and saw your thread here. So the option here is to reboot into fastboot, basically wipe everything and then flash the system blob from a stock ROM.
My main question is what if the person is on a TF300T bootloader, in my case 10.6.1.8. Would flashing the latest stock Asus JB ROM over 'system' for the TF200 replace the bootloader as well?

My main question is what if the person is on a TF300T bootloader, in my case 10.6.1.8. Would flashing the latest stock Asus JB ROM over 'system' for the TF200 replace the bootloader as well?

To answer myself, yes it does replace the bootloader. The latest ROM on Asus (from last Dec 2012) installs bootloader 1.00e ww_epad-10.4.2.18-20121122 a03
I installed stock TWRP 2.5.0 here for JB based on this thread and was able to get into TWRP and install the Hairybean Upgrade for 2.3, followed by the HB 2.3, and am now booting into the ROM. W00t! Great link in the OP flumpster.

adb reboot bootloader
When in recovery.
I just got a used prime and was trying to root/unlock/custom recovery/rom but I think I did something wrong.
This process seems a lot more delicate and volatile than my phone
I installed cwm through the CWM Rom Manager app after unlocking and rooting both of which went smoothly and device booted, and the device was properly rooted. After flashing recovery through CWM Rom Manager app I am ASUS boot screen
The one with "the device is unlocked" in the upper right corner and just sits in that state indefinitely. Can't do anything other than restart and get back to that screen. Any ideas?

Unfortunately you never read up on anything before attempting it. There are warnings everywhere on this forum saying not to use cwm on the prime and not to use rom manager and goo manager.
The last official version of cwm on the prime was for the ICS bootloader and if you flash that recovery onto jellybean bootloader then chances are you are going to brick yourself. Rom manager doesn't check what you are on and just installs the ICS version anyway. I reported this to Koush 2 years ago and he did nothing about it.
If you can't get to the bootloader or recovery by holding down volume down and power the same time and you also don't have nvflash backups then I am afraid that you are hard bricked.
There are only 2 options. Either pay Asus to fix it which will cost you more than you paid for it or you buy a motherboard off ebay or one with a smashed screen but still working and swap the motherboard out.
hypocritelecteur said:
Drat. Is there absolutely no chance, no method that might possibly work? No system dumps or backups or anything I can snag from another user to bootstrap my way back to functionality? I admit I jumped the gun here defs. I've been mucking with roms and hacks for android for years and never hard bricked anything and never run into a system this volatile. Didn't realize I was even being reckless! Just a different world I guess. This is however my first tab--are they in general more risky?

I know how you feel mate as before getting this tablet I have had numerous android devices and have had lots since and this is by far the easiest to hard brick. With other devices you can mess up but normally there is a method back in (odin etc) but Asus decided to tie it down completely.
The nvflash guys did a great job to make our devices brick proof but you have to make sure that you have your backups first. No one elses backups can be used. They are specific to your motherboard.
You can pick up motherboards quite cheap on ebay and someone here on one of the recent posts even put a tf300 motherboard in there instead as it was a lot cheaper ($50). They are basically the same machines anyway.
Was it unlocked when you got it ? If it was ask the original owner if he ever made nvflash backups.
tf201 maybe bricked

When in TWRP you should have adb access if you have the drivers installed.
Try.
Code:
adb reboot bootloader
to get you back to fastboot.
I managed to install original system blob. But what now? After start I have again four options, but my Prime is not booting into system or recovery. It always hang up on starting screen with ASUS logo or wit a dead robot.
Thank you.
---------- Post added at 09:05 PM ---------- Previous post was at 08:06 PM ----------
ok, now I am totally bricked, I restarted my Prime and it is black, even backlight is dead. It only reacts to power button, when I hold it, it vibrates after a while.
Fastboot or ADB cannot contol it.
Dammit
Did you ever manage to get your system back?
I used ADB to make a backup of my TF201.
I couldn't get ROM manager to flash a new ROM - every time RM restarted the TF201 I simply got the screen The Device is UnLocked together with the graphical menu for Recovery, Android, USB and Wipe and it just sat there and did nothing.
Eventually, I pushed the CWM ZIP into /SDCARD/ renamed it to UPDATE.ZIP then tried rebooting to see if it would treat that like an OTA update - it didn't.
So then I chose the Wipe option. It sat there for ages with nothing happening.
So I then rebooted - now I get the The Device is Unlocked in the top left hand corner, the ASUS logo in the middle and the Powered by NVIDIA`TEGRA` in the bottom right but it does not boot - it is bricked!
My PC no longer sees it in ADB or FASTBOOT so I can't either flash something or restore my carefully taken backup.
It won't boot into anything other than the screen above - so the key combination for Fastboot doesn't work any more.
Prior to all this it was running stock 4.1.1 but was successfully rooted and had been like that for quite some time.
Any ideas?
Kind Regards
Steve
Hi, I have the same problem than the last message. It's impossible!! any ideas please??

Hi Steve:
Well darn it, I'm another one with a completely bricked tf201. Without going into how I got there, I have the same situation as you... with "The Device is Unlocked" in the upper-left of the screen, "ASUS" in the center and "Powered by Tegra" in the lower right. If I boot with either just the power button, or the power botton and volume down, I get the affore-mentioned screen.
If I boot with power button and volume up, I get a completely black screen. I was very interested in whether you received a reply to your question?
I've noticed that the greater percentage of these questions, as I've described my system, remain unanswered. Not that I am complaining, but I am certainly interested in whether or not there is a remedy as of this date? I am not able to afford sending my tablet to ASUS, so would really appreciate any work arounds I could try.
Cheers man. Hope to hear from you.
Jim

[Q] Andrenaline Rom - Constant cycle - crash, reboot [Solved]

Just to be clear. Phone boots normally. All functions seem to work. After a minute or two phone locks up, then reboots. If phone is powered down it boots into recovery then locks up/freezes.
Apologize for length of this question but I wanted to be thorough. I have tried several things to resolve this, lots of reading and think I know a lot of things that are not causing the problem.
I installed the Andrenaline ROM, it ran fine for a couple of days then the phone started rebooting over and over again. Note it does not do this in TWRP (shutdown and reboot by itself) nor does it do it inHBoot. Only when I actually try to use the phone or apps after booting up. Initially I did the following all successfully:
I rooted using firewater using this thread http://forum.xda-developers.com/showthread.php?t=2632385 following the root all was fine and according to plan. No issues.
I then followed this thread http://forum.xda-developers.com/showthread.php?t=2498746
Finishing with this http://forum.xda-developers.com/htc-one-max/development/romsense6-adrenaline-4-4-2verizon-t2842331
Wanting to fix this and learn. I decided to go back to square one and even though TWRP seemed to be working I thought I should start there since I can see that I am rooted and have S off and the phone is unlocked.
That means I booted into the phone. Quickly ran adb and started in doing these steps:
adb devices #to make sure it was there
adb reboot bootloader #as per instructions all went well it booted into fastboot
fastboot flash recovery openrecovery-twrp-2.7.1.1-t6vzw.img
# Here seems to be the issue as it just says waiting for device ..... and nada thing happens. So while adb sees the device, runs the reboot of the bootloader it seems to be losing the connection or something at that point.
I am sure I have done something incorrectly. Can anyone lead me in the right direction toward resolving this? Any help would be greatly appreciated.
If somebody can just give me an idea of where the problem might be I would appreciate that. I thought about trying a different rom but system is so unstable I don't think I could get it loaded.
------------------------------------------------------------------------------------------------------------------
I think I was fooled because it ran well for a couple of days before I had issues. After re-reading the OP on the Adrenaline ROM page for about the 100th time I finally noticed ...
IF YOU HAVE ISSUES RUNNING CUSTOM KERNELS ON YOUR HTC ONE MAX, FLASH THIS IMMEDIATELY AFTER FLASHING THE ROM:

Flashing this from TWRP seems to have solved the issue. Thanks to all who at least read the question my apologies for wasting your time. I really did think I had read and seen everything. Actually read the whole thread and still missed that line in the opening post. Thanks to IAmTheOneTheyCallNeo for being so thorough and Flyhalf205 for having provided this. I can now go back to enjoying this fantastic ROM.
Glad you resolved it on your own. Good job
However, your issue with fastboot sounds like you don't really have working fastboot. While in fastboot, you do a "fastboot devices" instead of ADB devices. Then for recoveries it's a fastboot flash recovery nameofrecovery.img
Also, fastboot commands require a locked or re-locked bootloader to work for flashing things.

you are right
Thanks for the heads up. You are correct I have been working around this by using TWRP. I will do some research on how to get a working fastboot tomorrow. I am a linux only person but assume that being on Linux if I can get adb to work fastboot should work right?
Great call that you caught that it's really helpful to have a direction to head in.

As a matter of fact, I downloaded the necessary tools for Linux which contain working fastboot and adb (They are not the same thing and two different entities). If I have time tonight I'll zip it up and upload it for you with command line install instructions for your Linux system. If not the it'll be tomorrow.

Above and beyond the call sir. That would certainly save me time, effort and confusion. I know just enough to blow a toe or two off. Tomorrow or whenever you have time. Beggars and idiots should not be demanding and feeling like the latter after this fiasco. Really appreciate your help and support.

Download this file and unzip it: Androidv4.zip
then, navigate to the Android folder within terminal and launch the ADB-Install-Linux.sh:
Code:
. ADB-Install-Linux.sh
It will install adb and fastboot for linux.

Again many thanks.
I have some meetings this evening but will install and test in the morning. Sure it will work well.

Fastboot is now working properly. Thank you for your assistance.
No more questions. Worked all the way through the process from start to finish to make sure it was correct. Now 100% confident I have it and that it is correct. Thanks again for all the help.
