[Q] A510: Recovery verified failed - Acer Iconia A700 and A510

Guys, I am new here, so please be gentle. I was trying to update my iconia to JB, but everytime I tried i get a dead android with red exclamation. So I was playing with ICS rooting tool, and now it's even worse. When I try to boot in recovery mode i get this recovery failed error.
What should I do? Can somebody please help me.

Recovery verified failed
Hey guys,
i installed a stockrom from acer with this instructions http://forum.xda-developers.com/showthread.php?t=2042239 and it was completly done. I had Nothrills 700 Franken before.
i just answerd this question : When asked to avoid bootloader installation say "NO". This will restore the original bootloader and lock it again. You will not have CWM any more but I think this is what you want right? with YES because i wanted to keep cwm.
The tablet restarted normaly and when setting up acer told me that there is a update so i did the update.
Now the tablet restarted and i get the message : booting recovery kernel imag
and in the second line: Recovery verified fail...
in the middle of the screen you can see the acer logo.
WHAT CAN I DO NOW??? I can't reboot the tablet. Holding the power button get no impact. Shoud i wait till the battery is empyt and then?
I read smthg about fastboot and get a stock recovery. Is that a possibility? if yes, who will give me an instructions what i have to do.
Thx for your help.
But at the Moment i'm very desperate
P.S. Sorry for my bad english

Press the power off button longer, yesterday mine also didn't boot after a failed instalation of chainfire 3d. I needed to press like 30 sec or more.
You should also be able to reset, use a toothpick or something and press the reset button, enter recovery from there.

I brick my asus tf300t please help me

Hello guys,before with the rom hidro ponic 4.4 all was well.After i want change my rom and i've brick my asus after flash rom unofficial cm10..because the camera apk not found, and dispay is total green..I suppose the problem is the rom but after another flash rom the problem is same.On again the display is lock on the logo Asus and upstar on the little: the device unlock..stop.My asus there's no way to get it to recognize at pc and the driver installed not found..are't fastboot logo in Controll Pannel.I've not possilìbility to choce android--usb--wipe data.Help me please thank you sorry for my English
What about booting into recovery? Or fastboot?
As far as I understand your post Android isn't booting, but what if you hold volume-down when you turn on the tab?
I have almost the same problem. I flashed a bad boot blob (vanilla linux, not android) and now I'm stuck at the first Asus logo if I boot normally. But I still have fastboot and CWM recovery so I'm confident I can get it back into shape (even though a restore in CWM didn't help)
I think there's no way to unbrick the device,because I have the same problem.
I flash my device to official 4.1 and I found I lost root of my device
So I try to downgrade my device,but I failed...
Then I try to enter recovery and I failed again...
At last I try to wipe data of my device but it had no respond...
Of course,I had to reboot my device...
The result is:It bricked...
The symptom is just like the thread starter
What should I do???
I tried to contact the customer service of ASUS,but they said the device which unlocked by yourself couldn't get any warranty,even I willing to pay for it
(I think the customer service of ASUS is too bad,especially their attitude)
(I'm also sorry for my poor English...)
this is simple
download the asus jelly bean launcher.zip
from their website
unzip the launcher so its just the eepad 10.blahblah.zip
if it says update launcher you still need to extract this
then flash the twrp jelly bean recovery
now add the official jb rom to an external sd card
and flash
reboot
and voila
reboot again to fastboot and reflash recovery afterwards
and then flash root
worked for me

But my problem(the same as the thread starter) is:I couldn't enter either fastboot nor recovery
If I could enter one of it,I think I can fix it...

Thanks guys Today i can try the guide..we ope in God:angel:
I try twrp jb recovery but not function because the teerminal it's impossible go in download mode (down+power)....The Jig Usb forf Asus exist?
Hello guys, but for this type of brick no one has an answer? Method with nvflash can 'operate according to you ..? But I'm trying to appear APX and install the drivers as a guide is a company because it makes them install it
As far as I can see nvflash is coming to TF300T, it has been developed for T201 (http://androidroot.mobi/t3_nvflash/). But at least for TF201 they have to have fastboot first, so that may not help you.
If I understand you correctly nothing is booting and you have neither ADB nor fastboot access. In that case I don't think there's anything to do except wait and hope for a working nvflash or to try to have Asus fix it, but since the tab is unlocked they probably won't do so for free.
It seems this tab bricks easily.
I have the same problem, and I hope nvflash too. But I don't know nvflash in dev or no. This my best device which die first. Cry
Having the same problem here also. Only had the tf300t for less than a week.
Here is a sticky to a thread I made. I'm just waiting for people to put in a bunch of ideas. Hopefully NVFLASH doesn't need fastboot.

Hi !
...to force entry in recovery ...you need first to reset your device than go to recovery ;
- press for 10 sec. power button , release and quickly press volume down and power button at the same time ! -> normal the device should be entered in recovery ! Good luck ! :good:

...Tried it about 1000 times, not possible, but thanks anyway. No fastboot possible, NVFLASH won't be working either...
I asked our friends at androidroot.mobi if it would be possible to have this issue solved with NVFLASH, this is their response:
@AndroidRootMobi Is it worth waiting for NVFLASH on (very hard) softbricked TF300t? Or should I go to @Asus
‏@AndroidRootMobi
@Joanuz @ASUS Sorry. If/when we support TF300T, you will need device-specific files. So no brick recovery if you're already bricked.
It sucks, I know. I'll be sending mine back to ASUS tomorrow. No warranty. Hopefully a reflash will do the job (normally it should be around 75 euro), if the mainboard needs to be replaced, the total costs will be around 200... I will open a thread here once it's under repair. Good luck!
Same problem. Stucked at Asus Logo but i can go into recovery. What can I do? Help me please
My PC finds it as Fastboot.
Seem I'm no alone...
Seem I'm not the only one.
This morning I bricked my tablet, 5 minutes after I bought a wall charger on EBay... :crying:
As for now the only answers seem to be from people that don't read post good.
We can't get to use the recovery...
Again, if someone knows how reset the tablet prior booting...
I beleive that its the only other way.
The last possibility, buy a new one...
I believe the problem started before.
- I unlocked my tablet more that a month ago, at the Jelly Bean release.
- Rooted
- Installed the official release
- Everything went well, up to this morning
- I noticed that my Rom Manager Premium start to show adds
- Goo manager refused to install recovery script
- Then I tried to go in recovery, it fails.
- I said to myself that it was better to start from scratch
- I tried a Factory reset using setting menu.
- After this step the tablet started to show This device is unlocked
-After the last step the device wouldn't boot no other way...
I don't know what happened but it seem a bit strange that everything worked fine before this morning.
For sure I'll keep exploring ways to get out of this mess.
But if I have to buy another tablet, there's a chance that I'll go to a Nexus 7...
Good luck to all the other unfortunate that that are in the same boat.

Hi back,
After I bricked my device i sended back my tablet to canadian customer service.
At first the didn't wanna fix the proble and the service told me that he needed to change the motherboard.
I argue a while and after an email discussion whit the customer service agent, they told me that they would fix the problem for me THIS TIME.
This morning I received my tablet and everything seem to work fine, as it was reset to factory.
BUT, after I started to investigate, seem that in no time the cover removed.
And maybe the motherboard change is a trick to suck more money from the users.
In fact I can't understand why you'de have to change the motherboard after the tablet is bricked.
Maybe I'm wrong, but I find this way of doing thing awefull, and I consider lucker that I got outa this mess...
Good luck to the others unfortunates

No need waiting for NVFlash, it is here (check developer section) but will not work on unit if already messed up.
I have used two things that aren't mentioned here; I don't recommend either but if you are ready to ship off it might work for you as it did for me.
Both times were caused from ota updates.
1. use of reset button while powered on, if that fails to help, poweroff and reset button again.
2. let battery run down, put ac charger on power strip which is turned off but plugged into ac. Hold foot over power strip button, hold power and down volume on unit; mash power button on power strip with foot while holding power and down volume on unit.
I should have said neither of these fixed my unit; they just allowed me to get into fastboot to fix my unit.
Bricked TF300GT (please help)
Hello developers,
I have a bricked Transformer the goes in a loop flashing ASUS every 5 seconds or so. That was after having unlocked and then reset to factory default.
I have been reading a lot of articles at various forum for a solution. I have never seen something so confusing. Please is someone can point to me a page where the un-bricking is described step by step for that aparticular model?
Many thanks in advance
Yves
NB: I have tried the -volume and power button trick or the +volume power button that just make a USB connection on my PC

i got my tf300t bricked to.
got my tablet this weekend wanted to install cyanogenmod.
just did a week early'er a other one (the one for my mother)
that went well
my tablet installed de orginal 4.2.1 from asus.
Today wanted to install cyanogenmod.
run first de unlocker v8
the installed fastboot twrp421.blob
when i went to the twrp menu the cyanogenmod wont install, but the orginal wont start also not, it want nothing to start.
tryed with external sd.
ok i thought i want cmw so i run the recovery-clockwork-5.5.0.4-tf300t.img
went wel also.
i can only go to cwm but they are no file rights and still can install a zip or mount a sd internal or external.
now fastboot is not working
when i turn the tablet on it is going to cwm
wat i can do?
edit:
cmw version = v6.0.2.3
Me too! asus ask 230$ for replace new mainboard. I think they want eat money, because they already have nvfash to fix. 230$ can buy new item from amazon. I hate asus and never buy any thing of asus. Very bad support.

[A700] Bricked into "Boot image verified failed"

Unfortunately, I've bricked my Acer Tablet after trying to flash this ROM http://forum.xda-developers.com/showthread.php?t=1994294
The installscript finished the flash successfully, but after reboot, the bootloader only shows the message "Boot image verified failed" No booting and no CWM Recovery is available no more. I've tried several times to get into the fastboot mode with pressing the Power Button and Volume Button with the two knobs, but nothing helps. Neither switching the screenlock switch on and off. I figured out by trying, how to get into APX mode, but I don't know, if and how that could help me, solving my problem :/
Before I've tried to flash the ROM, I had CM10 with the Stock Bootloader in Unlocked Mode and CWM 6.0.2.3 Touch installed, but the Aroma Installer seems to have destroyed the CWM and locked my Bootloader again. Is there any way to unbrick the tablet now? Any help would be appreciated

Just let the battery run dry. Then let it boot up normally without pressing any buttons when the battery runs out by connecting it to your charger. Hope it works!
Thanks for the reply. I tried that, but nothing happens, just the indicator LED on the power button turns on orange. The tablet does not boot on itself, if I connect the charger. I have to press the power button, but this results again in "Boot image verified failed"
Edit: Update. I figured out how to get into fastboot. I read something on google, with switching the screenlock switch on and off. That doesnt worked for me: The thing was, to hold the power button AND the volume button with the two knobs, then the tablet starts, to release the power button and THEN, while still HOLDING the volume button pressed, to switch on and off the screenlock button. Then the bootloader starts into fastboot mode, going into androidsdk and typed in cmd "fastboot oem unlock" solved the problem. The ROM starts and everything is fine
Why you don't write into the mentioned thread? There seems to come the issues from then ask there, sorry can't understand why opening new thread instead asking there.
Also the first time heard sucha thing, I also change the rooms from cm10 to Jacobus, back to stock, on cool one and to cm and back, to test everything and try something out.
Never had issues buy this ways

I don't have the right to post in the proper thread, so I opened up a new one.
In order to install a JB based ROM, you need the JB compatible CWM. The version of CWM you used is apparently for ICS, so I am a little surprised it worked to install CM10. Where did this 6.0.2.3 come from? Use 6.0.1.5 from pawitp. I've used it and swapped/flashed ROMs at least ten times. Never encountered that issue (or any issue). As a matter of fact, I would just run Vorbeth's EasyRoot as it does all the grunt work for you. I've used it twice and it worked flawlessly.
It is just too late... bad luck for me today, I fullbricked the tablet, after performing a restore with CWM 6.0.1.4. Not bootloader, nothing. Just APX Mode.

Hi I had the same issue after flashing from CM10.1 to CoolOne. However I fixed it by unlocking the bootloader => reinstalling recovery => flashing CM 10.1 back.
Did you have any luck recovering from APX?

No, unfortunately not. I gave my tablet 2 weeks ago to the acer repair service and got it back today. The support said, that they have changed the mainboard and flashed the latest android on the tablet, but they did that on guarantee, so I didn't had to pay something ^^ Now it is running Android 4.1.1 Stock ROM from Acer.
Exact same problem
I am having the exact same problem. I am able to boot into recovery mode but then I get the android laying down with with the red triangle, question mark. My bootloader is unlocked but aftrer the update my screen is stucked on the ICONIA TAB startup screen.

[A700] bricked infinite boot loop

So starting from beginning, while playing some music, my A700 reboot and hang up in infinite loop of Acer and Iconia Tab logos. As Vol+Power was not responding, I sent it back to Acer for repair and received it back yesterday after they replaced motherboard (and microphone!?).
Cool.
But no, because after a couple of hours of re-installing, it reboot and finished in the same Logos loop, just after selecting Airplane mode.
So my question, can I re-flash this A700 with a complete clean stock ROM, as I have only access to Fastboot mod?
To reflash with fastboot, you'd need an unlocked bootloader. I wouldn't risk that if I were you.
It looks likes a hardware issue. A ROM contains drivers. Drivers control the hardware. When going into airplane mode, the drivers shut down some of the hardware components, like WIFI and Bluetooth. If you'd have a modded ROM, I'd say there's some driver issue which causes the tablet to crash (weird that it's stuck on bootloop, though). Since that's not the case, I'd say there's something wrong with your hardware.
To apply factory settings, did you do the right moves?:
http://forum.xda-developers.com/showthread.php?t=1861092
How did you enter fastboot mode?
Note that there's only a slight difference in going into fastboot or the factory reset mode. It's only a Vol + and -.
I was asking because I already flashed (in November) my 'previous' A700 with a stock ROM (because JB OTA update failed) without unlocking anything (but using Recovery).
You are probably right, it may be an hardware fault as it does exactly the same as first time and that Acer Support replaced complete motherboard. However it was looking at me very strange that I could get two hardware fault in the row.
I will give a try to the factory reset (I did not knew the move), thanks for the tips.
As far as I know it's not possible to flash a stock ROM with fastboot without unlocking the bootloader. Instead, you have to rename the stock ROM to update.zip and put it on your internal storage and then flash it by using recovery (also a button trick).
It could be that it's still the same hardware problem. Maybe Acer didn't know what was wrong and just replaced the motherboard. It's a massive repairing service center, so they're not going to search for everything.
Oh, an important question:
Did Acer, or did they not reinstall your tablet after they "repaired" it?
If not, then it might just be that. It's like your home pc. When you change your motherboard, you might need to reinstall the thing (or re-activate Windows, but that's not relevant ) to prevent errors.
Good luck and I hope you succeed
Ps. For what it's worth, you can also try to reflash your device with a beta ROM (it's beta because there isn't a stock ROM available which you can flash without having the bootloader unlocked). You can download it here. Now I'm not quite sure if you can update your tablet then, so it's coming out of beta. To flash it, do whatever I said with the renaming to update.zip (to transfer the ROM, you can use an sd card. It might just look for update.zip on the sdcard too). Please keep in mind that I'm not sure if you can update your tablet so it'll come out of beta. If you are going to try this, please post your results here

Considering the same issue happened under the same circumstances, we can pretty much rule out hardware failure. (they claim to have changed the mainboard.
If you look at the Acer 700 troubleshooting tree, they followed procedures. Or perhaps they "claimed" to have changed the system board, when in reality they just re-flashed the rom over the top so they can make more money by the hour. A common practice.
So the issue to me, seems to be either a faulty rom, or, faulty player. Were you using a player from the Play Store?
Also, would help to know which OS you were on. ICS or JB?
As with re-installing a rom, you should be able to get to the stock recovery. In which case, you could try
a. Re-installing the stock version rom again (renamed as update.zip)
b. Install an update.zip compatible with your region.
There are 2 types of boot loop.
1. Iconia.... this is a boot animation loop (stuck at boot animation)
2. Tab continually re-boots over and over. This is a boot-loop
3. Although not considered a boot-loop, stuck at the Acer logo.
So which do you have?
More than likely you have animation loop. Which means the OS is corrupted somehow.If I understand you correctly.
As with fastboot OEM unlock, you can do the following;
Flash a custom recovery
Flash a kernel (boot.img)
Flash a complete system image. This is not like flashing a Rom. It's an image file generated from another user who has a working 700.
As with unlocking your bootloader, well, it depends on if you wish to get things fixed. Or to return it yet again to Acer Repair. Can't tell you what to do Mate. But if it were me, I would take matters into my own hands after previous attempts.
MD
So I tried the following (yes, it is inverted relative to theory);
- Press [vol +] + [power]
- As soon as the tablet vibrates, let go of power and play several times [lock]
=> Fastboot mod, displaying "Bootloader vJB-653b3d3: Starting Fasboot USB download protocol"
- Press [vol-] + [power]
- As soon as the tablet vibrates, let go [power] and play [lock]
=> no effect
And as reminder, Recovery is not reachable.

So I guess I can not flash, because I do not have access to recovery, only to fastboot.

Yes they re-install OS as the A700 came back with a German Rom where I sent it with a French Rom.
Thanks a lot for your help :good:

Can you answer both questions MD asked you?
If you're running Jelly Bean, the bootloader has changed. This requires a different way of going in the recovery mode:
DЯΦ[email protected]П said:
With JB there is a change on the A700 (can't test on A701):
Boot into recovery:
- Press [vol-] + [power]
- Once the tablet vibrated, let go [power] and keep [vol-].
- Now the tablet vibrates a second time, let go [vol-] and press [vol+] quick
- Once the text that appears on the screen ("loading recovery kernel image"), let go [vol+].

Not really, first time it happened while playing music with google music player (reboot then loop).
Second time it was after setting the Airplane mode for night (reboot then loop).

I though the same but I found a 'technical paper' saying that board and microphone were changed, and both Wifi and Bluetooth Mac adresses have changed. So it seems they really changed motherboard.

Rom were 'different' when it happened; first was an FR and second was a DE. It was google stock player (only first time).
JB both times.

As with re-installing a rom, you should be able to get to the stock recovery. In which case, you could try
a. Re-installing the stock version rom again (renamed as update.zip)
b. Install an update.zip compatible with your region.

I do not have access to stock recovery, only fastboot mode

There are 2 types of boot loop.
1. Iconia.... this is a boot animation loop (stuck at boot animation)
2. Tab continually re-boots over and over. This is a boot-loop
3. Although not considered a boot-loop, stuck at the Acer logo.
So which do you have?
More than likely you have animation loop. Which means the OS is corrupted somehow.If I understand you correctly.

I have;
Acer Logo/animation -> Inconia Tab Logo/animation -> reboot -> Acer Logo/animation -> and so on...

As with fastboot OEM unlock, you can do the following;
Flash a custom recovery
Flash a kernel (boot.img)
Flash a complete system image. This is not like flashing a Rom. It's an image file generated from another user who has a working 700.
As with unlocking your bootloader, well, it depends on if you wish to get things fixed. Or to return it yet again to Acer Repair. Can't tell you what to do Mate. But if it were me, I would take matters into my own hands after previous attempts.

OK, that helps a lot, thanks. I guess what I would like to do is to flash a system Image. Where can I get one?
So far, I have Android SDK installed and Acer drivers installed (which bring me a "ADB interface"-"Acer fastboot interface" device in Windows Device manager)

I did a factrory reset/wipe data on my tf300 tab and now its stuck at the asus screen I cant even get it to turn off till the batteryruns down Power and volume down just turn the screen off for a second then back to asus screen.

Is your device unlocked? What version android were you running? And does nothing show up if you continue to hold the volume down and power button after it resets? Hopefully you'll be able to fastboot TWRP recovery. I encountered a similar problem when I tried to install a custom 4.1 ROM from stock Android 4.0.3, but my device was unlocked and I was able to successfully get things going after carefully searching these forums.

Yes it is unlocked Jellybean nothing happens if i keep holding the volume down and power except the screen goes off for a second the right back to the asus screen Fastboot won't work, it just says waiting for device My pc won't see it at all, not in device manager or anyuthing No apx either. If i could get fastboot to work i think i could fix it
I face a similar problem, but my fastboot is working. However, when I try to flash something through fastboot, the screen hangs until I reboot it. Also, if I choose one of the three options, it gives the message "Unrecoverable Bootloader Error."
I almost for got the details:
Bootloader - 10.6.1.18....I think...(it's JB 4.2.1, I'm sure)
Recovery - formerly twrp-2.4.4-jb.blob ( not 2.4.4-jb-42.blob)
Android - not booting
Device unlocked
Error (in red letters) - Unrecoverable bootloader error)
And no, I do not have NVFlash.
Any thing that I might've missed? Please let me know. ASUS wants $99 just to troubleshoot over the phone. I don't think so.
Also same problem. Fastboot 'sees' the TF300 device but does not flash.
I have the same problem. Fastboot 'sees' the TF300 device but does not flash. If somone has come up with a solution for this, could you please share, it would be greatly appreciated. Did Asus finally release NVflash for JB 4.2? It seems it is the only possible way of solving this, or isn't it?
Thanks for your help

What happened in the end? Did you go to ASUS and get it repaired? How much did it cost?
Hi guys,
I solved the problem with the bootloader error (0x0000000) assistance in sending the TF300T. I told him that during the upgrade something must have gone wrong and the OS did not boot anymore. They repaired free of charge. My dealer to whom I entrusted the tablet is Mediaworld (a chain of electronic products Italian). I hope you can serve

The good thing about development phone like Moto G are that you can never brick your phone. It is very much recoverable. Try unlocking bootloader and then flash official firmware from this link http://sbf.droid-developers.org/phone.php?device=14
Use this link to unlock bootloader,
https://accounts.motorola.com/ssoau...ct/standalone/bootloader/unlock-your-device-b
You can bring your phone back to life.
Hope it helps.

I would not wait for two weeks for replacement when we can bring the phone to life within 30min.
I agree a risk element in it. If the phone is basically faulty, then it is not worth trying the way I suggested. Has this worked before you started mess around?
Good luck..

If the phone is basically faulty (a potential hardware issue) the last thing one should do is unlock the bootloader and lose the warranty.
Sent from my Nexus 5
If you have ordered from flipkart Just call them and pretend that its not turning on at all.....and they will give you a hand to hand replacement!
I can return phone but it cost more then 60 EUR via DHL and i must wait long time...
Today i will try to unlock bootloader and flash firmware. Thanks you all, have you more suggestions?
I dont know what happened. This is strange problem because telephone work fine 5 hours and after power off, i see only Motorola Logo. I hope that i will not miss guarranty when i unlock bootloader.
Unlock device is finished. Can you give me tutorial for flashing stock firmware? I am noob
U used this tutorial: http://www.theandroidsoul.com/install-moto-g-uk-generic-firmwarestock-rom/

Is there any solution? If not, how i can lock bootloader because now i lose guarranty

I had exactly the same issue, after I unlocked the bootloader this happened to me, don't worry is not bricked just a software issue with some providers firmwares, what did I do? The good about this is, you should be able to put it in fastboot.
Read all before try it please
* I unlocked the bootloader (seems like you already did it)
* I flashed CWM http://forum.xda-developers.com/showthread.php?t=2563599
Here the next issue was I needed to flash a ROM but I wasn't able to put any file in my device even mouting the USB in CWM or adb push, so: sideload
* I downloaded this rom http://forum.xda-developers.com/showthread.php?t=2606943 (you could use other but that worked for me)
* I Put the zip file in the fastboot directory
* I turned on my device in recovery mode (CWM, you can do it by the fastboot, select recovery, use vol up to enter, vol down to move, power button doesn't work here).
* Wipe factory, cache and dalvik (just in case I think factory wipe is enough)
* I went to the option flash from zip file, flash from sideload (or similar not sure about the name but it says sideload)
adb sideload myromfile.zip
once the adb finish, CWM will notify you and you can flash your rom regularly. It will finish, then you should reboot, It should take about 5 minutes for the first boot. Then my phone worked again.
Sorry if I said something wrong, first time I talk here and I felt identified with your issue and wanted to help you.
Thank you. I flashed CWM but i can not enter to it. When i hold volume down + power button i enter in fastboot flash mode. How i can enter to recovery cwm? When i enter to recovery trough fastboot mode nothing happened. Phone has restart and appeared moto logo. When i flash it i got ".mismatched partition size".
Is there any tutorial for me ? I am very frustrated with this phone
sounds like the phone might be faulty if it happened and you didnt do anything to cause it ,
anyway another option for you is to try a external reset,you have attempted too flash other firmwares so not 100% sure it will work but give it a try through fastboot recovery.
click the link below and halfway down the page follow the instruction for "external reset"
https://motorola-global-portal.cust..._detail/a_id/97329/p/30,6720,9050/action/auth
This is my steps:
-Flash this falcon_retgb_user_4.3_14.10.0Q3.X-76-LGG-8_54_release-keys-cid7-Retail_GB via this tutorial http://www.theandroidsoul.com/install-moto-g-uk-generic-firmwarestock-rom/
-flash CWM V3 or V2
Do i need to flash some other stock ROM before i do external reset? EDIT; external reset does not work becase i can not enter to recovery and wipe data/cache...

Except it isn't a development phone and of course you can brick it. Try erasing the bootloader and recovery and see how you get on then. Im pretty sure it'd be bricked??
To OP - you should have returned phone especially as you are a noob, no offence but a noob trying to recover a phone which has 'broken' by itself is not going to end well especially as its impossible to tell if its hardware or software issue in the first place.
I wish you luck though.

To get into CWM after flash it, go to fastboot mode, then in the menu, use ONLY vol down and move to the recovery option, once in the recovery option push vol up.
It also could be you phone has a fault from factory.

You can perfeclty recover an erased or corrupt bootloader, and from there flash anything you want, including recovery. Yeah, it's an unbrickable phone.

Your phone seems to be fine. the only option worth a try is to flash official firmware that should go ok with a locked bootloader forget about custom recovery and rooms
and in any case do not unlock the bootloader until you some how solve this and in the picture you posted the phone already is in flash mode just make your PC to recognize your phone by installing the necessary drivers and flash
