So I have had this US beta streak since around January, the one that says 'Dell Confidential' at boot up, but it's never really worked correctly. I purchased it from a person that I know that got it through some sort of beta testing; the details weren't provided and I didn't press him for them. Anyways, I am currently trying to get the clockwork recovery flashed and able to be booted into, although the streak is giving me every possible problem I can imagine. I'll try to provide as much background info as I possibly can.
Firmware: 1.5
Baseband Version AUS_090716_01_BOSS_EVT2_3135
Kernel Version 2.6.27
Build Number QTC_3135
OEM Version: AustinBuild_090724_03_boss_evt2_3135_FixTouchSuspend
Under About Phone > Status
IMEI 011954000020995
IMEI SV 00
Service Tag FF8R6K1 (which dell.com cannot find)
The Problems:
When I try to get into bootloader to get into fastboot, by holding the camera button down while hitting the power button, rather than going into the screen that is shown in all of the different tutorial threads, I instead go into some sort of a diagnostic menu that doesn't have an option for fastboot, as much as I have seen. There is a picture attached below.
I (think) that I can get the phone recognized by adb, although I am not totally positive. When in cmd in windows, and I type adb devices, instead of getting the proper serial number of my devices, it shows instead 0123456789ABCDE (I may not have that exact, but it does start at 0 and ends in hex at E or F, I can't remember right now and don't have it connected at the moment.)
There was one time where I was able to flash recovery.clockwork.img to where it said that it successfully flashed the img, but when I go to try and boot into recovery by holding both volume up and down at the same time, and then hitting power, the phone just hangs at a blank, black screen. It will stay there for 30 minutes and not do a thing, I can't see it via adb or fastboot.
So I then gave recovery.alt.img a shot, was able to successfully flash that, or so it told me that it was successful, but still the same problem: just a black screen.
The reason that I think that it actually was working was that after flashing the recovery image both times, I sent the command adb reboot recovery, and the phone reboots, but not into recovery, just into android. adb reboot-bootloader doesn't work at all and returns an error or nothing, I can't remember.
I then focused my attention on trying to get fastboot to work, assuming that adb was not working at all. This is where fastboot gets strange. The only way for me to get the command 'fastboot devices' to show anything at all is by holding the volume down button prior and then hitting the power button to start it. This puts the phone into essentially a 'soft brick', which my friend calls 'safe mode', where it gets totally stuck at the 'Dell Confidential' screen and will not progress past it no matter what.
So, once I am in 'safe mode', I am able to then issue a 'fastboot devices' command, which ... partially works? I hope that my totally unsure tone of voice was able to be conveyed through that message, because the info returned once that command is sent is totally confusing to me. Unlike before, where I feel as though the Streak is just lying to me by saying 0123...DEF for the device ID, for fastboot devices it just gives me a question mark .. yes, simply a ?
The weird thing is that it will follow commands. I was able to flash recovery.clockwork.img to the streak, it gave me a read out that said successful, and I got very excited. And then I pulled the battery, put it back in, held both the volume buttons, and .... the same result, the black screen. So, not allowing myself to be deterred, I got right back into fastboot, or at least my quasi working version of fastboot which may not be working at all, and flashed recovery.alt.img, which turned around and told me that it was successful as well. This time, not allowing myself to get excited, I pulled the battery and, with both volume buttons held down, hit power to try to get into recovery.
Again, I was let down and found only a blank screen. At this point, I have no idea what else to try. With the bootloader not being where it's suppose to be, not really being able to get into fastboot or adb (I think), I turn to xda to try and find some answers. Does anyone have a suggestion as to what I am doing wrong or might be missing. I am hoping that it is something that is really obvious that I feel very stupid, like I'm hitting the wrong set of volume buttons, but ... I don't think it's that easy.
Again, I feel as though the phone was getting the commands from fastboot because I sent fastboot reboot recovery, and the phone rebooted, just not into recovery but android. Same thing for bootloader, it just didn't work at all
Also, as for android 1.5 itself, almost nothing works. This appears to be running a very early edition of android where most apps just end up with: Sorry! No applicatons can perform this action, so the One touch root is kind of out of the question.
I was able to do the dialer unlock method to get EMList, but the similarities end there. I don't have the Unknown sources option or anything else after leaving dialer.
Any and all suggestions are appreciated and will be accepted and followed (within reason). I'm just at the point where I'm hoping that it's not totally broken and that with determination and hard work and some critical thinking I (we) will be able to get it working again. Hopefully it isn't a paperweight.
Thanks,
Thursday

This is how I unbricked my TF300T that had no rom installed and a wrong bootloader/recovery combination. (4.2 bootloader with TWRP recovery JB version). Hope it helps.:good:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I have the same on my TF300t and A700 - but it seems i just managed to get my TF300t back
i tried all fastboot (reflashing recovery, boot, system etc) no dice - especially since writing system was done after 3 secs all the time.
Here how i restored my TF300T JB
download your appropriate lates firmware from Asus (WW, US etc.) and extract the zip twice so you have your blob file
install your device drivers if needed (i used Google SDK ones) (and as a Tip Win8 sucks for Fastboot stuff so try to get Win7 Vista XP for this)
Reset your device with a paperclip/needle (about 2 cm down of your sdcard slot) and hold vol-down to enter fastboot
(the folowing i did at least 10 times already but didn't erase misc)
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adb\TF300t\blob (this is my path - your's may vary depending where you stored your blob) ((also this was the first time i saw the loading bar while flashing)*
fastboot -i 0x0B05 reboot
* it also took a lot longer as it should:
C:\>fastboot -i 0x0B05 flash system c:\adb\TF300t\blob
erasing 'system'...
OKAY [ 1.695s]
sending 'system' (800935 KB)...
OKAY [133.121s]
writing 'system'...
OKAY [153.973s]
finished. total time: 288.789s
im now setting my tab up to get back to CM (which initially caused this sh1theap due to autoupdate error, same as my A700 got bricked )
hope i could help you out!
cheers

This part was me now -ozkrtech <--- (credits to me)
In addition to that, if you simply can't see your device using the command "adb devices" go check on device manager if you see a device called just "Transformer" with a yellow icon indicating it needs a driver, and manually update driver, select "browse my computer for drivers" and then select let me pick from a list of device drivers on my computer" there you will see a list of like 3 different drivers, one of them says "bootloader" and one of the others says "adb" (i think they self explain) but just in case try with each one of them you can keep on switching drivers until you get your device recognized by the command "adb devices".
You should be asking yourself... whats the right moment to do an "adb devices" command? well my tablet same as -Buster's tablet had the wrong recovery menu flashed (wrong bootloader version) and it just kept booting into the corrupted recovery (in my case TWRP) with the "can't mount anything" and "what's the password" issue. When you get to password screen just hit cancel and try the "adb devices" commando and you'll see it gets recognized with your device serial number.
Once your device gets recognized by "adb devices" command you will proceed to use "adb reboot-bootloader" command and the tablet will reboot into the menu that had 4 options but now have 3 options and its missing the fastboot option (don't panic) in the last bootloader it is auto-fastboot mode when you reach that screen with just 3 options in it now (yeah is the screen with the RCK option) at this point try "fastboot devices" command to see if your device gets recognized same as "adb devices" procedure, it should get recognized with a different serial number (don't know why, maybe that number isn't a serial number), at this time you are SO LUCKY! now you will follow what I posted at the beginning from that other dude ---> (-Buster) or follow his link --- > http://forum.xda-developers.com/showpost.php?p=44244313&postcount=12
And you'll have an unbricked tf300t in no time =) (I personally used the stock but newest Asus ROM) 4.2.1 (10.6.1.27.1) and it worked flawlessly.
**NOTE** don't turn off nor reset your device once you have formatted the partitions, no need for that (don't know what happends but it might get really hard bricked) just proceed to flash the stock rom after erasing the partitions.
I'm 100% positive this will work if your device is in same state as ours. (had TWRP for JB) then updated bootloader to version 4.2 and forgot to update twrp to version 4.2 or installed twrp version JB by mistake and lost fastboot and TWRP is asking password.
Hope it helps. Let me know your status and if it worked for you.
So I am in the same boat as I flashed the wrong twrp. My device shows up under adb devices and I can boot into the bootloader using adb reboot-bootloader. However, once there, I can not get the device recognized with fastboot. I have tried messing with the drivers like you suggested but nothing will get it to show up with fastboot. Anybody have advice on where to go from here?
So extra info. The device bootloops into twrp 2.6. The only way I can boot into fastboot mode is with adb reboot-bootloader and I can get into APX. I can also boot directly into my current ROM (Slim beta 3) by selecting android in the bootloader menu. I have tried flashing proper recovery through flashify, which is says was successful, but the wrong twrp never gets overwritten. Rebooting the device will send it back to twrp.
Thanks if anyone can help
Thanks, man! It took a while to find this thread, but this was exactly my problem. The adb driver in windows was the pre-solution to help get back to the fastboot server in the bootloader. Awesome information. Thanks again!
I have tried "adb reboot-bootloader" and then adb devices and fastboot devices and neither will show the tab listed while the tab reaches that screen with just 3 options. I have uninstalled reinstalled drivers, it does show in device manager as Asus Android Composite ADB Interface but when running the command it will not list the tablet. Any suggestions?
Hello!
A few days ago I tried to root my Asus TF300T because before that, I changed the lcd and the touchscreen from FPC-1 to G01 version. So I had to root and update touchscreen's firmware to 02-3011-4820.ekt. I already updated with last firmware from asus.com. First, I installed a TRWP recovery but was useless since the touchscreen doesn't worked. So I tried to rewrite CWM recovery. I reset it and I don't remember exactly if I begun to install or not CWM but when I tried to wipe data (Vol- + Power), the tablet has freezed. After a few minutes I did a hardware reset (pin hole). Since that, the tablet freeze with "Device Unlocked", Asus logo and nVidia. The device was already unlocked. I don't have any backup from it. No fastboot, no adb. Just APX mode. Is it possible to do something with it anymore? I tried BootTools2, extracted bloobs from last version of firmware, tryed to flash them with nvflash and wheelie but vainly. What is the next step? I'm a beginner!
Remember please I cannot go in fastboot recovery menu, only apx. Thank you in advance!
I can not thank you enough!!! my tablet is now working I honestly though it was done for aha THANK YOU!!!
Howdy, folks. I recently bricked my tablet thanks to a bad install of CWM, but following the OP's guide I was successfully able to reflash stock firmware and the device runs fine now.
However, upon reflashing said firmware, it became apparent to me (from reading various threads in the development subforum), that I would need to downgrade to an older firmware version to reflash TWRP. So I did that successfully, but now I am having a problem similar, or perhaps identical, to that of Bionicbowtieguy, in that ADB appears to be broken for my tablet. I have tried uninstalling and reinstalling the Asus usb drivers, in addition to reinstalling/updating all of the ADB software. Fastboot still works fine, but as such I'm unable to root using Motochop's rooting kit (I know there are other methods out there), nor am I able to flash a new recovery. I have also tried repeatedly reflashing the older stock in the hopes that ADB would magically start working again to no avail.
Does anyone have any suggestions to getting ADB to work for my tablet again? I have scoured the web, particularly these forums, for days looking for an answer, but haven't turned anything up yet. Any help would be greatly appreciated.
Gave back 10 years of my life that I lost once I discovered I flashed the wrong TWRP version. Can't thank you enough man.

Same here!
Thank you OP for making this a topic even if you didn't come up with it you made it a thread that has saved a few people like myself money and headaches. Literally I just stumbled on this thread 10 minutes after I told my wife is be Tablet shipping Black Friday. Thank you sir.
Thank you.
I did this on a hackintosh running OSX since on Win 8.1 fastboot kept crashing.
March of this year I bricked my tablet during that 1 week period where nobody knew that TWRP was broken + fastboot freezing.
I must have tried everything, Maybe that erase misc was the key factor for success.
I was about to sell this for what I could get or send it to asus, now I can use it again!
How are you guys getting your tablet into fastboot mode? I've tried power on with volume down, the reset hole with volume down, and letting the battery die then recharge, then power on with volume down... Nothing. What am I doing wrong?

Indeed. You are a god among men. Thank you so much
This worked! I thought I was out of luck. Thanks a lot.
I accidentally flashed an incomparable version of twrp. It would only boot straight into recovery and I couldn't get into recovery. TWRP kept asking for a password even though I never set one up and it wouldn't mount the internal storage or sd card.
I had to follow the instructions at the bottom to intall the drivers so adb and fastboot to work. After that I followed the instructions at the top.
The only thing different I did was skip the "fastboot erase boot" step. I was afraid that would really brick my device if I screwed up (Does this really erase the bootaloader leaving the device with no bootloader?).
Just wondering how long the fastboot window sits displaying < waiting for device > ? All my drivers are ok and I my pad shows up fine as a fastboot device in windows.
Cheers

They do not sit at all they will go right to it. You must not have the right combination yet. Keep trying.
Took me awhile to get the link.

FIXED!
BY GOD, I have no words for how incredible grateful I am right now! You not only saved my TF300T's life but also a lot of money for me and gave me another lesson of Android insight.
Thanks so much for this!
Let me know if I can return the favor somehow!

Hi. I think I'm having the same problem as some of the others in this thread.
Background: Tablet is unlocked, JB Rom (Paranoid Android) was installed since March, along with TWRP recovery. In preparation of installing CM11, I used Android Terminal Emulator to install the latest TWRP from a *.blob file, but I found that the latest TWRP is still not CM11-ready...
Setup to Issue: Last night, I decided I wanted to put CM11 on my TF300T. TWRP doesn't have a compatible recovery out for CM11 (install of CM11 rom fails every time), so I reinstalled the paranoid android ROM, and attempted to get the latest recovery from clockworkmod. On cwm's website, they only have choices for "transformer" "transformer prime" and "transformer infinity" which, when downloaded, have tf101, tf201, and tf700 in their filenames. (No tf300, that is)
So... I attempted to install the tf201 recovery (closest to mine, right?) by renaming the file cwm.blob, and using android terminal emulator to install it, the same way I did with TWRP. The first few times I tried and rebooted into recovery... TWRP was still installed... which was weird to me.
The big problem: Ultimately... when I rebooted the tablet, I just see the initial "ASUS" screen with "The Device is UnLocked." in the top-left corner. When I hold the power button to turn it off... it powers back on within a few seconds, and stays at the "ASUS" screen again. It will not stay off... and will not show anything but the "ASUS" splash screen. (With one exception, described later - "the only ray of hope...") If I hold the volume up or down buttons when powering on the device, absolutely nothing different happens. (since it doesn't STAY off... I've tried all kinds of different combinations of pushing/holding the appropriate buttons for when the tablet comes back on) IMPORTANT: I never see the "three icons" as expected when holding the volume button(s). No RCK, USB, etc... when the unit turns back on, it goes to the ASUS screen, and stays there until the battery dies. As a result... I can't get into recovery, fastboot, or APX or whatever in the traditional way.
Pressing the reset button alone, or reset + volume down has the effect of temporarily turning off the unit and then on again, the same as holding the power button to turn it off and letting it turn itself back on again.
The only ray of hope that I have is that *sometimes* if I press reset + volume up with the USB cable connected to a computer... the screen will STAY BLACK, but the "device connected" sound will play on my PC (Win 7 x64) as if I just plugged the tablet into USB on my computer, and I will get a message that it's trying to install an APX device. However, it eventually tells me that the device driver could not be installed. The screen on the tablet stays black in this case... until I reset it, hold the power button, etc.
So... I'm not opposed to (or unfamiliar with) using fastboot or any other command-line app to resurrect my tablet... I just haven't been able to get it into a condition that I can try something like that yet.
Is there any hope for my tablet? Somebody please help me. I'm open to sending a few bucks via paypal or google wallet to anyone that can lead me to a resolution. That would be cheaper than buying a new tablet... not to mention the priceless value of the progress I have in Fieldrunners 2. lol.
Thanks for your time!

same problem reboot back to twrp
well i may be stupid because i can't understand why i have tried a couple of commands and i still get the same problem reset volume down still goes back to twrp and ask for a password can someone please explain this in alittle more detail and what commands i also get the waiting for device in my commands is there another way to push these files into this device tf201 please help is there a way to do something in the twrp recovery like terminal command
I was a fool for flashing wrong recovery!

I have exactly this! I hope someone knows the answer for this issue. Else the tablet will learn how to fly!
I tried to push the reset button as described earlier but nothing changes. Not able to go into recovery Just stuck at ASUS in the middle NVidia in the bottomright corner en upperleft corner 'this device is unlocked'
Hey guys,
I recently went to power on my Nexus 7 (2013) after a weekend of having it off, and it got stuck on the white Google start up screen with no further responses. Holding power the devices still turns off, and I am able to get into Bootloader and Recovery. From bootloader "start" just sends it back to the Google start up screen. I'm able to enter Recovery but the Android logo with the red warning triangle doesn't have the No Command script below it, Power and Vol. Up gets me into the Recovery menu. Entering recovery I get errors of : Can't open, failed to mount, can't mount etc which continues as I try to clear the cache, and wide the partition (I'd post pictures but I can't as a new poster). Moving on I tried some of the guides to flashing a new factory image with fastboot or Adb. Since I don't have normal access to the device I'm sure sure is USB debugging was enabled or not, but in bootloader that shouldn't matter correct? Anyways here is where I hit my snag, my device is still in LOCKED bootloader, and the fastboot oem unlock command gets me to the unlock bootloader screen, but after I select and confirm the option the device freezes and no progress is made. From that screen I am still able to turn it off by holding the power button down, so I'm somewhat confused about it becoming unresponsive to the unlock bootloader command. All of the other fastboot commands like fastboot erase cache come back with "Failed: Too many Links". From my knowledge I've checked through everything I can do software wise, and I was curious if you guys had any input before attributing this all to a hardware failure? I've got some experience rooting and flashing custom ROMS on my phone so I have somewhat of an understand of all this but its by no means vast. Thanks for the help, and I tried to provide you with as much info as possible but I'll attempt to answer additional questions to the best of my ability.

A clear explanation of the problem alone with everything that you have tried will do for reporting hardware/software issues and also help others help you.

After a whole 24 hours of using Lollipop and found the phone was unusable (phone would ring, but not give any other indication of an incoming call) in some ways, and lacking in other features, I decided it was time to go back to 4.4.4.
So I followed the instructions from Google(/android/nexus/images) , downloaded the 4.4.4 Occam factory image, and installed Minimal ADB and Fastboot. It took a while playing with drivers to get the device to show properly with the adb devices command, but it finally did, and was able to command it to reboot bootloader.
Everything still looking good. Still following the instructions, did the oem unlock, wiping it to factory settings, and then ran flash-all.bat. It went through that, the phone restarted into the bootloader, this time showing the Kitkat loading images instead of Lollipop, I think I'm home free.
I'm in the bootloader again now and notice adb devices is no longer showing the phone, so I try oem lock, and the phone screen updates to show locked. Odd, but it worked. I now used the volume buttons to select power off, and power off the device.
Powering on, the phone shows the Kitkat white "Google" on the screen, but that's it. I try powering it off again, and it restarts itself. I try getting it to display in adb devices, and nothing. The phone has been sitting at this screen for half an hour now with no change.
Using volume down+power I'm able to get it back into fastboot mode, but nothing will work from there. Start, recovery mode, and power off all result in the same thing: phone looks like it's turning on, but sits forever just showing the white "Google" on the screen. Abd devices still shows no devices attached, yet the phone still accepts oem lock and unlock commands, so I tried to run flash-all.bat again, but it just gives a 'command write failed(unknown error)'.
I'm kinda stumped now, and I haven't been able to find anything on this kind of issue. I'm hoping someone might have some experience or be able to suggest something my limited experience hasn't exposed me to before.

Using volume down+power I'm able to get it back into fastboot mode, but nothing will work from there. Start, recovery mode, and power off all result in the same thing: phone looks like it's turning on, but sits forever just showing the white "Google" on the screen. Abd devices still shows no devices attached, yet the phone still accepts oem lock and unlock commands, so I tried to run flash-all.bat again, but it just gives a 'command write failed(unknown error)'.
I'm kinda stumped now, and I haven't been able to find anything on this kind of issue. I'm hoping someone might have some experience or be able to suggest something my limited experience hasn't exposed me to before.

ADB needs a booted up android to work, it wont work in bootloader mode. Another requirement is that usb debugging must be enabled in dev options. Fastboot works only in bootloader mode and doesnt need usb debugging.
Download wugfresh toolkit.. Use it to restore your device and DISABLE FORCE FLASH

I've successfully rooted my T-Mobile LG Leon, and I've successfully installed TWRP, but for the life of me, I can't get the phone to boot into recovery. I can RE-boot into recovery from TWRP manager, but I can't actually boot into it from a fully powered-down state. I've tried every combination of the power and volume buttons I can think of, and nothing ever works. Download Mode works, the factory restore menu works, but I CANNOT get into recovery. Is there a very specific set of instructions anywhere that I can follow?
EDIT: Okay, I finally figured it out: You need to actually select to do a factory reset, and it throws you into the recovery menu.
Yeah, it was because the stock recovery doesn't exist as a menu, when you're running stock and enter the adb command "adb reboot recovery" it will reboot to the "factory reset mode" and the actual file of this mode is stored on partition named "recovery". Choosing the factory reset option boots the custom recovery because it replaces the said " factory reset mode" and that's the trick.
You can access recovery from the powered off state by holding volume down and power on until you see the lg sign. Without letting go of volume down, depress on the power button before clicking it back in and holding both buttons in until you see twrp pop up.
If you reboot to recovery now, it''ll probally say secure booting error. Simply go to the Developer options and enable OEM Unlock and that'll make you boot to it
You boot in the download mode by holding the vol up 10 seconds and during this 10 seconds you insert the usb. The LG Leon brand screen will come on a minute then it will go into download mode. It says not to unplug until firmware is done updating. So I guess you should have your custom recovery or whatever before you do this. I have only got this far, and thusly it sits. All Dressd up with no where to go...haha

can't find "enable OEM" at all in developer options. have phone hooked computer, and on, it's sending and receiving. No OEM. Isn't there.
See, I'm trying to root this without using KingUser. Since I found that it was pretty easy to do from the very beginning with Samsung, and I just don't see any way to do it here. I can't get ADB Devices command to see the phone.

I think I have the same issue, but I rooted my phone using kingroot, I haven't tested the adb commands, I just want to use twrp but no luck, it says Secure booting error and I can't find OEM Unlock option in Developer Menu.

I got a good way to get it rooted with SuperSU. Ran a command window script I found out there. It worked and now I have SuperSU root. I also figured out how to get into recovery. It looks as though my phone is not the standard LEON that people are talking about here. It's got a few designations, and the T Mobile site advertises a Leon that seems very similar and is called by the name most are using..
Anyhow my LG Leon is designated as a H320. It also carries a v10 desiganation, v10b. The v10 is variable from a-h or a-i. It would seem that once it is updated to 5.1.1 android it gets upped, and becomes unrootable. Mine being a v10b was rootable, but it took me a while to get used to it, and make the command window work.
Unfortunately for me one of many things I tried before getting it rooted, was ADB fastboot. And since this told me to wait for too long, I pulled the plug on it and pulled the battery to get back into "normal" operations. Perhaps I should have waited, because after finding out a few things about the phone, I discovered the true way to get it into recovery:
The real way into recovery for my phone, is to (from power off state) hold the volume up, a few seconds, then plug the USB cable which is going to the computer into the phone. While holding the volume up until it comes to recovery. This will activate the recovery, (Now for me it activates that fastboot command line...and does nothing else). This was the bit of information I could have used from the beginning, that no one knows. All these places tell you to hold the power and volume up, and then let off power when the screen changes, but that never worked even once. You just hold the volume, and plug the USB from computer. This works.
For me it goes into a "FASTBOOT" header at the bottom of the screen that never changes.
I believe it does this because of my unsuccessful attempt to fastboot it before. And it does not have the right driver to get recognized in the computer. So I'm screwed as far as the recovery goes now.
It is rooted though. And it doesn't seem to have any alternate ROMS available anyways. so we're dealing with the loss of the recovery.
When I do try to use an app such as TWRP manager or CWM (ROM) Manager to reboot into recovery, I get a "boot certification verification -1" error instead of the fastboot line at the bottom of the startup screen and it boots normally from there. So many people asked about this "boot certification verification -1" and NO answers are available anywhere online. So that's where it stands for this phone right now.
Anyone know what driver I should use to get the thing recognized in the computer? I have downloaded a zipped fastboot tools, and it won't get recognized inside the driver manager as "android" only as "unknown device" so I can't use that route....I'm thinking about doing a factory reset to try to erase the fastboot attempt. That may not help though. Anyone?

I dunno, I have the H340AR, with this phones happens the same that with the Samsung Galaxy Ace 3, there are, 3G versions, 4G versions, regional versions, etc.. GA3 have 7275R, 7275B, 7272L, 7272T, I dunno, maybe if we could get a device tree for a H340 and an H320 we could make some TWRP and CM compiling, but I just can't figure it out how to make a device tree or even where to begin..
I successfully rooted my H340AR with Kingroot, it works like a charm. I haven't tried fastboot and I tried to install TWRP in this link https://dl.twrp.me/c50/ but I get that F error "Secure booting error". I guess I have my bootloader locked, so I'm trying to figure out how to unlock my bootloader.
I'm trying to contact with some developers and see if anyone can help me build a device tree.

Hi, I have that same phone H340AR LTE. I rooted it with Kingroot and also tried to use TWRP to gen into recovery and got that Security error. I only pulled out the baterry and turn it on again so it booted normally. I made a factory reset because I read that it could be a problem of OTA firmware update. Then I installed TWRP and BusyBox again and tried to get into recovery from TWRP option. When I did that, it showed up the Android lying in his back with a red triangle. I pulled a out the battery again and yes, it seems very dumb and simple but it worked and could reboot the phone.
However, I can't get into recovery from TWRP yet. I read that the problem with us not being able to unlock the bootloader(we don't have the OEM option) is because Leon has Lollipop 5.0.1 and OEM is for 5.1.1

This device has a locked bootloader. If you flash a custom recovery on it, it will not boot into recovery, but will report a security issue. You will lose all recovery functionality, including factory reset, adb, fastboot. If your phone fails to boot, you have a brick.
Hi, just bought a phone for my son secondhand, it's going to be sold again if I can't fix this! The phone was sold cheap as it had software issues (of course) so I figured I could fix these and get it going (install custom recovery, ROM etc). I'm slightly stumped at the moment, so maybe you can help me.
The phone's defaulting to the bootloader screen, lots of info on this but the key thing I noticed was that it says 'the device is locked status code: 2'.
Clicking 'start' takes me a 'warning unlocked bootloader screen' then it runs through the 'hello moto' startup screen and back to bootloader
Clicking 'recovery' - there is definitely no working recovery on it, I just a get the dead robot with 'no command' underneath.
Clicking 'Factory Mode' allows me so far through the startup (after the bootloader unlocked warning), and you can get so far through setting it up, but because the battery is so low (it's permanently on with the bootloader when plugged in) it never seems to charge up enough, and either way the screen freezes at or around the final setup steps and then it reverts back to bootloader. I thought if I got into developer options and security, I could enable the USB debugging, OEM unlock etc, but no go there.
I've installed Motorola USB drivers but it doesn't seem to be registering on the PC (Windows 10).
There is some suggestion on other forums (less reputable!) that the locked status code may mean the bootloader has been relocked, but this seems contrary to what the phone is telling me.
Any ideas welcome, thanks - it's a lovely phone, just not much use at the moment.

OK, some progress, I have now unlocked the bootloader, so have the UNLOCKED Status Code:3 which is good, unfortunately has not yet helped with my issues. I can't use ADB, but MFastboot tool is working, so can run commands from that (hence me getting to that stage). Tried reinstalling firmware, may try and do this again now bootloader unlocked....

I have now managed to flash stock firmwares using Mfastboot tool, but hasn't unfortunately fixed the boot up issues. However, I have now worked out how to access the recovery, by reading other posts on different Motorola phones:
boot to bootloader, power+vol down
in bootloader select recovery using the volume up/down buttons, press power button to select
phone boots into 'recovery,' showing the dead android with no command
at this point hold down the power and volume up, then release volume up but keep power held down
phones boots, by magic, into android recovery, where you can factory reset, wipe cache adb sideload and install from SD card
I now need to try and get a flashable recovery to sideload, as the attempts to flash it don't work for me. The OS I seem to be on is reteu 7.1.1, so I will try and go for a lower version, and see if that allows me to flash the custom recovery I desperately need.
But....things are improving slowly....:laugh:
