[Q] Nexus 7 (2013) lte soft bricked, no backup - Nexus 7 (2013) Q&A

Hi, so I installed franco kernel on my nexus 7 2013 LTE and it messed it up. Got it stuck on boot loop. Unfortunately I didn’t do a backup. So now I can’t restore. The worst thing is my laptop doesn’t recognize it when I take it to bootloader mode or recovery. I reformatted it from recovery so I think I lost root but I can still access the bootloader and recovery. Will appreciate suggestions on how to go about this.

Did you try reflashing the ROM?

Do you have any files on the SD card? It seems that is your only hope if your computer doesn't recognize it while in bootloader or recovery.

Do you have the correct drivers installed? If so, try removing them and re-installing. There's plenty of info to be found on XDA and the rest of the web on how to do that.
You can also try:
-another USB port on your laptop
-change your USB cable (you'd be surprised on how often this works)
-use another computer

Did you not make a nandroid backup of the last rom set-up you had on there that you can load from clockworkmod?
Can you boot into your phone and do a factory reset?
That will at least bring you back to stock rom
yes i did a nand back up and for some reason its not there i cant get the phone to recover at all. it seems as if the rom i put in there is the only rom.
when i tried to do a factory reset it comes back to that rom that i installed
Have you read this thread?
yes and i followed the steps to the T and i still get a device not recognized in the cmd. i have windows 7 64x and i was hoping that it will work but it didnt. i know there has to be a way to re-write the rom. all i need is access to the sd card and i can run nand.

decompress android sdk (check on google for the sdk package, is quite small), then go inside the "tools" folder (I assume you have already your drivers installed).
then go on command prompt, and
Code:
adb logcat
will show the logcat.
Code:
adb logcat > bootlog.txt
will create the boot log (you won't actually see anything on screen since the output is redirected on the txt file.
You can:
start your phone
type adb logcat
CTRL+C when the phone is booted.
It will automatically stop if a reset occurs.

I don't think you have the usb brick as you would have no access to SD card, and the phone would still boot. You would also see qualcomm devices listed when you connect usb.
Have you tried booting without the sim and SD card?

Without SIM & SD phone started fine
... but after reinsert abowe its all the same. =/
I can lunch it with SIM only.
So i cant lunch it with SD inserted.
Can You verify what is the problem?
Or how can i?
Maby should i try with goldcard?
if it boots with SIM and no SD then its the SD thats the issue.
You can try to format the SD again and reparition it, if that dont work then it must be a faulty SD card.

[Q] HELP! Desire won't boot up, Clockwork mod recovery accessible

This is my first post on this forum (figures I'll jump head in when I have a serious issue,ha?)
Ok here goes:
My Issue: HTC Desire is stuck on boot-up screen with Green HTC logo forever.
How it happened: I tried flashing a script using ROM Manager that was supposed to correct some local language settings, over my current rom.
Phone state before action: Worked beautifully using Modaco R8 RC1 ROM. Phone is of course rooted.
Why I can't solve it myself: Well, this is my first serious issue (well, I hope it's not serious, actually!) with phone, which i've had for about a week , so I'm relatively a n00b.
-- I can access Clockworkmod recovery. However, under NANDROID RESTORE there are no files. I have no idea why, because I DID a full nandroid backup before that install. I have a copy of all the IMG files of the last working setup on my windows machine hard drive, and my assumption is that maybe I accidentally moved the files to the hard drive after i did that backup, instead of copying them.
Now -
1) Can I somehow restore the phone to a working state without the nandroid backup, using some other function of the CW Mod recovery?
2) Can I somehow connect the phone via USB to the computer and get it to read the Micro SD card so I could maybe move the IMG files I have back to SD Card (using a mounting option)?
3) Anything else I could try?
If nothing else, please just calm me down if you can and let me know the phone is fixable and not bricked because I can access recovery?! That would at least help me go through the night...
last note: Before I flashed the zip, ROM Manager said my CW Mod version is 2.0.5.7. Within the recovery itself, it says the version is only 2.0.5.1. Don't know why that is , and if it is important.

You could read the SD Card directly with your computer. If you don't already have a microSD/USB reader, they are very cheap and will prove very useful in situations exactly like this one.

You are right! Indeed they are very cheap, but, unfortunately it's going to be a game of patience for me, because it's late evening right now and the shops are closed.
That's why I Was wondering if there's an option to mount SD using HBOOT or Recovery so I could end this ordeal tonight...
Anyway, The fact I could get into CM Recovery means the phone was not permanently damaged, right?
Right, if you can boot into recovery it's a good sign.
I have an N1, not a Desire, but in my CM recovery menu under "partitions menu" there is a "mount USB storage" option. Try that?
Alternately if you own any other phone with a microSD slot that can mount it via USB, it could be your makeshift USB reader.
I have had a similar issue before! What I actually ended up doing was pushing the files using ADB. Its quite easy and I'm sure you can find lots of threads on how to use it. Once the files are pushed to your SD card you can then restore it
FIXED!

Problem solved! And yeah, that's how I ended up doing it.. no micro SD card reader was needed..
I installed HTC Sync for the device drivers... then connected the Desire with the USB cable .. and worked out of the problem using ADB commands..
luckily, the guy whose update I installed that caused the problem has the same ROM as myself, so I installed his framework.jar file , and the machine is fine yet again!

[Q] Dropped my phone - Now stuck in bootscreen

Hello guys,
I woke up too early this morning, and i accidentally knocked my phone off the stairs. It fell about 2 meters, bounced and then fell another meter, bounced and fell another meter and stopped.
Thankfully it was in a silicon case (i think that's what made it bounce) and there are no visible damages.
I picked it up, and it seemed to be working. After a few secs it went into sleep mode and would not wake up.
I removed the battery and rebooted, and i got the HTC screen, then the nexus boot screen and it stays stuck on the nexus boot.
I then entered recovery mode and thought i would try and restore my backup. I get the following message:
E: Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
(No such file or directory)
E: Can't mount /sdcard
I took off the SD card, put it my pc and it works just fine.
I got another SD card, copied a rom onto it and tried to reinstall through recovery.
I did a wipe/data factory reset and tried to install the rom.
I got the same message...
Is my Desire toast? It's only six months old...
I was running Defrost6.1 and using psfMod 0.9.7.2 as my recovery.
Any advice would be extremely appreciated.
Thanks
aalex
UPDATE
I did another wipe data / factory reset, and i rebooted.
The rom starts up, without any of my previous settings of course, but I still cannot mount my SD card.
From file manager, it seems that it is being mounted, but no files are listed...
When i try with gallery it reports "SD card unmounted or not present".
Any insights?

With your SD card in your phone go into settings then storage and unmount SD card. Then format your SD card from your phones menu and it should mount the SD card see if that worked.

Hi ste1164,
Thanks for responding. My problem is that my phone cannot pickup the existence of an SD card.
This is a typical USB-brick. I've had one a few weeks ago. You should look at this thread: http://forum.xda-developers.com/showthread.php?t=691639&highlight=usb+brick.
If you're new to this, it can be hard to get it working again. Just let me know if you have any problems. It took me a few hours to get it done
From fastboot via ADB, execute "fastboot oem enableqxdm 0" and then reboot it with "fastboot reboot" command.
See if it works.
If you don't remember how to do the above, just search.

its not a usb brick, thats a software brick.... it sounds to me like you have a corrupt sd card, sd cards are very delecate and this can happen from a sudden impact, try formatting the card in windows explorer, obviously you cannot format your sd-ext using windows so try gparted or ubuntu to format your other partition.

Can't be sdcard, op said tried sdcard in PC and tried different sdcard...same result, must be sdcard reader or something.
You never know, might be a USB brick, just happened before the drop and was brought on by the reset...but I agree probably is hardware fault.
Is it possible to flash stock rom from fastboot without sdcard? Could try warranty repair then...

sorry i didnt notice that, could be a usb brick but like i said thats S/W related and i doubt dropping your phone could cause such an error, +1 suppose the sudden reset could cause the usb brick especially if the device was reading or writing to the sd card when it happened, could also be the sd card reader in the device has been damaged or one of the internal components. can the device read the sim card? if it dosent, could be a usb brick
Just a thought...is the sdcard reader attached by a ribbon? (never seen the inside of my desire, hope I never have to)
I'm sure I've heard of a few desires that can't read sdcard anymore, I reckon it's either attached by ribbon or it's the most delicate part of the phone.
I'm hoping it's a loose ribbon because that's an easy fix, even I could do that.
Hey guys,
Thanks to all of you for responding.
My sim card works just fine. I can make and receive calls, texts, go online via 3g and Wifi, connect through bluetooth. As far as i can tell, my phone does everythind it did before except mount an SD card. Also, the android market keeps crashing, and if i try and download anything from the net i get a prompt saying that i need an sd card to download.
So far I took the SD card and put it in my pc. I formated it, tried again but it didnt work.
I then tried a brand new sd card and that didn't work either.
However, I did not format the old card's ext2 partition, and the new sd doesn't have an ext partition yet.
Would this point to a USB Brick as mentioned above?
Would it be possible for me to flash the stock rom on the device?
Thanks once again, to all of you.

Yes, that should solve your problem. I had the same problem a few weeks ago, but that included a malfunctioning usb, even charging didn't work correctly.
To fix the sd-card, you should run the above command using the tool fastboot, available in the Android sdk. After downloading, cd to the tools folder in the sdk and then run the command while your phone is connected to your pc in fastboot mode. Then it should work again.

Hey koenvbeek,
Thanks for the help. I think i may need a bit more of it
Here is what i did so far:
I used Nephrons guide to download and install ADB.
I then rebooted to bootloader. The phone displays "fastboot" and then when i plug it in it dispalys fastboot-usb
I then went to the ADB tools directory and tried to run the command.
I got a message saying the command cannot be run because adbwinapi.dll is missing from my system, and asking me to reinstall everything...
Clearly i made a mistake somewhere but where?
I don't think you made a mistake
Either the requested file is missing, or it can't be used by your computer. First check if the file is present. If not, google for it.
If it is present, your computer can't use it for some reason. Are you on a 64-bit OS? If you're on Vista/7: did you open the cmd promt as admin?
Yeah, nothing wrong, it's just that the API library is missing.
Download it from the attachment here, and put it in the "tools" folder, then try again.
Edit: As you can see it's in an archive, since dll attachment is not enabled here, so extract the file from it.

Half-Bricked phone?

So I've got a bit of a weird situation here. I was doing a nandroid backup today in preperation of updating to the newest version of Cy mod and at the end it failed. I let it time out and reboot on its own.
After that point my phone was completely borked. The phone will get stuck in a boot loop (black to htc logo, to black over and over) if it's not connected to a computer, however if it's connected via usb it'll boot up into Android.
If it's not connected though, I can get into fast boot, but if I try to get to recovery from there it will get stuck in a boot loop (unless, oddly enough, it is connected via usb to a computer at the time, it seem to have no trouble booting if connected via usb).
Even so, if I do have it connected via usb and manage to boot into android or the bootloader it cannot mount the SD card. I've confirmed that the SD card is properly seated, but do not have the ability to test out other sd cards.
Even more weird is that WiFi and Bluetooth now suddenly will refuse to start up. They worked just fine before I attempted to do the nandroid backup.
And even wierder still, earlier today, after the whole phone went to **** but before now, USB debugging would still work in android but now it will refuse to work, so I can't even adb into it while it's booted. I also, for some reason, can't seem to adb into it while it's in fastboot either.
Basically, right now I have no sd card, and apparently no ability to adb into the phone, it'll boot loop if started without being connected to a pc, but will boot to android if it is connected.
I can still download things from the phone's browser, and I have access to the terminal on the phone. Can this be fixed or am I pretty much boned?

Rom: CyanogenMod 7.0.3.1

Recovery: Rom Manager
Unfortunately I'm really not in a position to change any of those things unless you can come up for a solution to fix the sd card or my problems connecting with ADP, or if I can somehow flash it with the terminal while in android proper.
ROM Manager is not a recovery, it's an app, which makes me think you have CWM.
Since you can boot up while connected and you can get into fastboot (Can you get into Hboot?), I'd drop the PC36IMG for Amon Ra onto your SD Card via a card reader, then boot up by using Vol Down \ Power and when it scans and asks to update, hit yes. then try to get into recovery.
If that fails, you may need to reformat your card, again via a card reader, then run the RUU for your phone and try to flash recovery again.

Yeah, sorry I meant CWM, I had a brain fart there.
I cannot mount the SD card. Even if I had a card reader to put that stuff on it I wouldn't be able to use it to update from it, although, maybe the drivers that fastboot run from were unaffected by whatever screwed up my phone, so it might be able to update if I grab a card reader. I'll try this and report back.
Also, I have no issues getting into CWM when my phone is hooked up to my computer via usb, it just will not mount the sd card.
You don't need to mount the SD Card if Hboot will see the file on it.
Okay, here's the deal. Hboot will see a pc36img.zip. It'll load it up, check it, and then won't give me the option to update from it.
Yes I have the engineering hboot (0.76.2000)
If it's any help, I think this all started when I was doing a nandroid backup and the sd card ran out of space.
Is it possible to update an RUU from my computer without using adb?

First thing you're going to need to do is clear some space off your SD card.
Check on the root of it and see if you have any files with "qxdm" in the name. If so, you can use the SD Card fix from here to get your SD card mounted again (you have to be connected to a PC in fastboot mode, with the correct drivers installed, for it to work).
It sounds like your partitions are out of whack, so you really need to flash your misc partition, and that may normalize your device. Problem is, you need working adb to do that. If you can't get into recovery, then that won't work. Can you boot up your device at all? Is it recognized at all over USB? If not, as long as it'll stay on and it's rooted, you can use Wireless ADB to flash the misc partition. I did it here.
When cleaning up your sd check the LOST.DIR folder it may be several gb's and you can just erase the whole folder its similar to the recycle bin on windows and can be safely emptied if its full as it is mostly incomplete or partial files that are created during sd scan on boot and/or created if you unplug the phone from your pc with out properly disconnecting the storage first by right clicking the drive and clicking eject usb drive
