Hi all,
my nexus wont start after (failed?!) flashing with factory image. bootloader and recovery mode are accessable. i have no backup so i need to flash a new img, but my tablet wont be recognized by my computer anymore(adb drivers not working?!). i tried to deinstall and reinstall the adb drivers alrdy. Device manager shows nexus 7 as Android Phone with "Android Bootloader interface" i cant install adb drivers while in bootloader. in recovery mode i succeeded installing the adb drivers and the tablet is shown correctly in device manager... i need help dont know what to do :crying: .. any suggestions ?
ADB and fastboot drivers are different.

ok sry wasnt patient enough to see... ya well this all makes sense to someone who knows what hes doing but to a noob like me? i thought i alrdy installed fastboot drivers since i unrooted the device a month ago? do i need to deinstall the driver "Android Phone with "Android Bootloader interface"" in device manager first, before applying the new fastboot drivers? pls help me through this i think i damaged enough alrdy ..
no. ADB and fastboot require separate drivers. just install the drivers required for n7 fastboot. there was a link in that list.
there are tutorials here on xda, as well as youtube videos and tutorials on other sites. take a little initiative and learn the ropes. it will help you out later on.

Just relax and take your time.
If your tablet can go into fastboot mode, it is fine and will get better; the only thing standing between it's current state and being brought back to life is a little learning on your part.
Now you see what the problems are with using a toolkit - because they hide all the gory details from you, when the smallest thing goes wrong you are totally helpless due to a lack of understanding about what things are going on underneath the hood. And as it turns out, what "goes on under the hood" isn't really all that complicated either if you do things the full manual way.
Which is not to say that you can not simply just use the toolkit again; if you previously successfully installed drivers that allowed you to talk to the tablet in all of these modes:
- fastboot
- adb w/ custom recovery booted
- adb with Android booted
then it is not evident that you need to be fooling with drivers.
I suggest you read this thread, from start to finish
[GUIDE] Flashing a Factory Image with fastboot / return to stock
Then, go over to your toolkit thread and read it from start to finish. You will see that there are & have been plenty of people in circumstances nearly identical to yours.
good luck
hey thx for ur replies! im a lil more calm now than i was 30 min !
the big problem i still have is that my tablet will show up as Androidphone/Android Bootloader Interface not as an unknown device or as the Nexus 7 it is when i plug it in.. so i cant install the drivers am i correct? well i tried it a few times .. deinstalled and reinstalled .. the problem persists? anyone familiar with that? when i change into Recovery Modus it will show up as Androidphone/Google Nexus ADB Interface.. so my first steps to get rid of this mess would be ...?

that does not sound like a problem to me at all.
You communicate with the device using the "fastboot" program when it is in bootloader/fastboot mode, and with the "adb" program when it is in custom recovery boot.
What you see in the device manager appears to be completely normal - In different modes it shows up in different places. It's not supposed to show up with the same driver in different modes.
Code:
fastboot devices
will show you whether you are communicating successfully with the device when it is in bootloader/fastboot mode, and
Code:
adb devices
will show you whether you are communicating successfully with the device in recovery mode.
I suppose your toolkit has some stoopid menu or buttons someplace that will allow you to test for exactly the same thing. Now all you need to do is stop posting here and read a little bit.
good luck

well i did read quite a lot today :crying: i cant find my device when i type in adb devices, im pretty sure i have the right drivers installed since i followed the instructions step by step.
this guy seems to have the same problem: http://forum.xda-developers.com/showthread.php?t=1808076
could someone tell me if this could be a possible solution :http://stackoverflow.com/questions/...e-over-usb-via-adb-devices-from-windows-7-x64
also would it be possible to just get into the bootloader (since thats the purpose of adb drivers and i can do this) and just proceed with fastboot commands ? if i type in fastboot devices the tablet will show up...
In your first post, you indicated that you couldn't connect to the tablet that was in bootloader mode with adb.
And then you were told - once vaguely and once quite specifically - that *nobody* can communicate with the tablet using adb when the tablet is in bootloader/fastboot mode.
As stated previously, use the "fastboot" program when the tablet is in bootloader mode, and use the "adb" program when the tablet is booted to the custom recovery (or the regular android boot if USB debugging has been enabled).
You can use either one of these modes to effect a rescue so long as they are working correctly - they don't need to both be working. Eventually you would want that to be the case, but for the moment why don't you just stick with what is working for you.
If you get a device ID printed when you execute "fastboot devices" when the tablet is in boot loader/fastboot mode, that is all you need to reinstall a factory ROM, using nothing but fastboot.
thx for pointing me in the right direction! so i started flashing with the fastboot commands... as soon i get to: fastboot flash radio radio-tilapia-1231_0.17.0_1025.img
i receive:
error: cannot load 'radio-tilapia-1231_0.17.0_1025.img': No error
any clues? thx in advance

Well, I can't see what instructions you are following, and there is a possibility of sensitivity to an exact sequence. In particular, is a
fastboot reboot-bootloader
performed after the bootloader is flashed, but before the radio is flashed? It might be important that you are performing the radio flash from one bootloader vs. the other. Just a guess. (Along the same lines, do you see something unexpected happening, such as a boot to the recovery after the radio flash command?)
There are some other threads on this I think. (I have a grouper device not tilapia) But I thought that those threads were about problems with radio flashing when a custom recovery (rather than a stock recovery) was on the phone, but that was for applying the OTA package for tilapia rather than flashing directly from fastboot.
-------------------------------------------------------
[Edit] whoops, wait a minute.... "cannot load"
When you run fastboot from the command line, the file names you give are relative to the current directory. Did you move those image files into the same directory that you are executing the "fastboot" command from?
Alternately you can specify the full pathname to wherever you unpacked the files, for instance
fastboot flash radio C:\myfolder\unpacked\googlen7\4.2.2\radio-tilapia-1231_0.17.0_1025.img

I would complete the rest of the steps first and see if everything is still working. Your device *should* still work just fine with an old radio firmware. (Boot it up and see what radio firmware the OS reports on the Settings... about device... status page).
I'll pull down the tilapia image and tell you what MD5 I observe for the radio image.
just to verify, you actually have the 3g/4g model? or just the wifi only model. if wifi only, there is no radio

the google - provided instructions (flash-all.sh) have 10 second sleeps after the bootloader resets - are you waiting long enough?
fastboot oem unlock
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-tilapia-4.18.img
fastboot reboot-bootloader
sleep 10
fastboot flash radio radio-tilapia-1231_0.17.0_1205.img
fastboot reboot-bootloader
sleep 10
Also - something to check since you are rebooting the bootloader - does the device show up correctly in the Windows device manager? (Sometimes with soft reboots I have found the need to pull the USB cable and plug it back in to the PC).
adb can see my ZTE Open, but if I reboot into recovery mode or the bootloader, fastboot doesn't see it.
Could someone please explain to me why this happens and how I can fix it?
I *do* see the device in fastboot. You just have to make sure you have TWO udev-rules in place, since the device shows up with a different vendorid (the one of goolgle, not ZTE) when booted in fastboot.
Unfortunately, I have bricked my device that's why I can't post you the exact ids. But I think it was 1d13 for Google.
Please note that somehow flashing over fastboot does not work with the ZTE open, erase and flash work but it seems after transfering the data to the phone it somehow aborts flashing.

Some help here http://pof.eslack.org/2013/07/05/zte-open-firefoxos-phone-root-and-first-impressions/
I've tried everything I could find with a google search but I haven't found anybody with a similar problem. I cannot boot into recovery mode as every time I select recovery mode I get sent back to the fastboot screen. I can use normal boot and my phone starts up fine but choosing recovery mode just brings me through an endless loop of going to the fastboot screen. Anybody know a way around this?

It usually occurs simply because it cannot boot into recovery. This may be due to accidentally wiping the recovery partition, thus having no recovery to boot to at all, or that you flashed an incompatible recovery onto your device.
Fret not, just a few simple commands should get your phone back alive and kicking.
First, download the recovery.img (ZE550KL) at https://drive.google.com/open?id=0B6QXDUz9wzc9bUZaOHJsTzBhcVk
Then, boot your device into recovery mode.
Once done, type the command, in order,
fastboot flash recovery recovery.img
fastboot oem reboot-recovery
Do take note that you would need to have ADB tools installed, a reliable connection to your computer, ASUS drivers in order for your device to be detected, and some knowledge on where to place the recovery.img in order for the commands above to work. If you need any help, please feel free to ask. Also, since you did not state the variant of your device, I had put the ZE550KL recovery.img instead. If your device is of another variant, please inform me immediately and I will get the recovery.img up for you.

Thanks so much, this worked. I have a ze551ML but I had a stock recovery already on my drive. I've been trying to install the twrp recovery for the last two days but have been completely unable. Although the "fastboot oem reboot-recovery" failed as adb didn't recognize the OEM remote. Any idea why the most up to date twrp recovery has not worked in the least?

You need to unlock the bootloader first. There are plenty of guides online about how to do this, unofficial and officially. Also, there's a dedicated forum for your device variant, named "ASUS ZenFone 2"
This forum here is for the Laser variants.

Hi
I would like to ask for some advice.
I've recently soft bricked my MI2S. I can boot to recovery (TWRP 2.8.1) and fastboot. The phone isn't recognised by Windows or Ubuntu, so I can't flash anything with fastboot. Actually, fastboot, adb or MiFlash don't detect the phone. I've tried to use a USB stick with an OTG cable, but TWRP doesn't detect the USB stick. If I boot to system, it stays on the MI logo (I can wait a full night, it won't change).
My question is, do I have a problem with my USB port? I'm equipped to solder a new one, if necessary. Or is my connection problem due to another reason? I wouldn't want to go through soldering if it is for nothing. Especially, when I started to mess up with the phone, it was locked with a different MI account (it was my wife's account, but it took me a few days to connect the dots together), and I couldn't connect with MiFlash, adb or fastboot either.
The steps I did to get it soft bricked:
Flashed TWRP 2.8.1 with fastboot
Rebooted to recovery
Rebooted to MIUI (a few times)
Attempted to flash TWRP 3.5.0 (my memory fails a bit there, I think I did it via fastboot)
The last didn't work because I'm still on TWRP 2.8.1
And I can't add any more zip file to flash via recovery, nor can I use adb sideload or flash with fastboot.
Any advice or comments are more than welcome. You may just have an idea that I didn't think of.
Regards
Matt
Quick update:
I don't know if you would agree, but I can't see my issue to be a software one (the device not being recognised)
I've ordered a USB port directly from China and I'll see if I can unbrick the phone from that point.
It's great that you can still access to recovery and fastboot.
First, I advice you to back up your data.
If you cannot use adb sideload or flash with fastboot.
Try in fastboot mode
- fastboot erase cache;
- fastboot erase system;
- fastboot erase userdata.
See if that can solve your issue.
Hey guys!
It's been a while since I've used my Mi A1. I turned it back on after a very long time and it was stuck on the android screen as if there was nothing to boot into so I tried booting into my recovery but there was nothing there either. I figured I probably formatted some stuff a while ago but I don't really remember what happened. Anyways, here's what I did next:
I could only boot into fastboot so I ran the command
Code:
fastboot boot path/to/tissot/twrp.img
but that didn't work.
So I flash the img to boot and tried rebooting to recovery but I was stuck on the android logo and again. I then again had to wait for my battery to run out before I could do anything else (I couldn't enter fastboot again. Only works when the phone is off for some reason)
I then erased the system partition using fastboot and tried booting into the recovery again but no luck. Can someone help me?
I know I messed up... big time. Someone save me
EDIT: Some more details
I tried two recoveries. The Pitch Black on XDA and also the standard "twrp-3.3.1-0-tissot.img" but had the same issue of getting stuck at the splash screen for both.
Also, I remember using Android 10 before all this happened.
EDIT 2: I ran the following commands:
Code:
fastboot set_active a
Code:
fastboot flash boot path/to/tissot/twrp.img
And I can now use the button combination to boot into recovery but I still get stuck on the splash screen
Hi,
have you fixed it? I face the same/similar issue, that I stuck at twrp splash screen after booting in twrp with fastboot
Code:
fastboot boot twrp-3.5.2_9-0-tissot.img
I have erased/formatted everything (userdata, cache, boot) and also tried to reflash the original rom with mi flash tool, but without success.
Any ideas?
MBR might be creating problem , try clean install with mi flash tool with official ROM .
@MIN313 Thanks for your response.
I tried to flash the official rom with the flash tool ( see here: https://forum.xda-developers.com/t/mi-a1-flash-sec-error.4139573/#_=_ ) .

Does MiFlash recognize your phone? If not, try instaling ADB drivers nd disable driver enforcment,
To kick device out of diagnostic mode and into QDLoader you will need either:
1) A "deep flash" cable
2) Take the phone apart and bridge test points
There are guides online for both, you can Google. You can make deep flash cable yourself fairly easily with a spare USB cable. Testpoint location is found easily via Google and can be bridged with tweezers or small flat-head screw driver.
