I tried looking around the forums to see if someone has had this problem before. Couldn't find something similar.
I had stock 4.0.3 installed and I saw today that 4.0.4 was being pushed out. Since 4.0.3 wasn't a stock build I tried to downgrade to 2.3.6 in order to keep everything stock. I rooted the phone, installed the ROM Manager and flashed 2.3.6 through Clockworkmod Recovery. Everything went smoothly but when I powered on the phone force quit messages kept popping up and I can't get past the welcome screen. When I go into Fastboot mode and try to go in Recovery mode it just shows the Android symbol and a warning sign. I tried flashing a recovery .zip file I found online through fastboot but couldn't manage to do it (I'm on Mac OSX)
Can someone please help me? I'm completely desperate and wouldn't care about erasing everything (I think I already did, actually).
Thanks in advance.
flash a recovery.img
that multiple fc happened to me when i installed a i9023 rom on my i9020a.
unzip the recovery.zip and flash the .img file through fastboot and make sure you have the right rom for your model
Thank man, but that's what I tried to do. I got confused and wrote that it was a .zip up there. I'm really confused and couldn't flash the .img. Could you walk me through it? or point me to a thread that shows me how to do it?
im not sure how a mac is set up, i can walk you through flashing it on windows through command prompt ...
Please do that. I guess I can try to work it out.
Thanks

memorize that lol it saved me.
you can skip the root part, but it explains how to set up the pc so it'll read the nexus with the correct drivers and whatnot, and what commands to run to flash the recovery. then when youre in the recovery, mount as usb, copy over 2.3.6 (the right one!) and install from zip.
I just tried that. I get this message: "error: cannot load 'twrp-crespo-2.0.0RC0.img'" I don't know what to do!
Can you get into boot loader mode?
Have you tried to use Odin?

Did you unlock your bootloader?
Code:
fastboot oem unlock
Well,
basically subject says all.
I tried to install zulu99 Full android rom 2.1.
basically 'fastboot flash system system.img worked' but 'fastboot -w' failed ('no space left' error).
So I rebooted hoping to reflash a nandroid backup but now the box keeps on rebooting into twrp trying to wipe cache and data but failing. after a while it stops and black screen appears.
I attach the screen it presents when reboots.
Please tell me I didn't trash 220 euros.
Thanks.

Theres a hardware method to boot into the bootloader, this i think you can test, just to see if you can at least get into bootloader.....nothing more
Details in the official nvidia link
http://nv-tegra.nvidia.com/gitweb/?...ob_plain;f=README_SHIELD;hb=rel-22r18-partner
There's a thread here on the "questions" thread with users reporting that the timing of the hardware method can be a pain in the you know where.............might be worth looking into that thread for their experiences in booting the bootloader using the hardware method
Disclaimer:If your brave enough to risk a brick, read on
I suspect this might be the 2.1 stock/twrp issue........current twrp, or current stock dont play nice
Its a good sign that SOMETHINGS loading, rather then NOTHING booting, but dont know if theirs a solution
My analysis of the situation, of what little i know, the -w (wipe) command was expecting a stock recovery but instead got twrp, which is why your in this situation.........maybe, i stress maybe, if you could reflash stock again, you might be able to boot into android stock again and try full android again, leaving out twrp, until a twrp fix is found
Edit
Saying that, if the bootloader is, as i suspect, now using twrp to flash things, then you might be boned....... im no expert on bootloaders, stock "recoveries" and how they work, so i might be wrong on that
Reports around here say that 1.3 stock firmware is the recommended back to stock firmware, apparently, flashing any other firmware versions, bring their own issues.............
From 1.3 stock, use nvidias official OTA to upgrade from 1.3 stock, to 2.1 stock, then try 2.1 full android again...........note, i dont think you can skip firmwares i.e. you have to upgrade to 1.4, then to 2.0, then to 2.1, alot of downloading.......the OTA does'nt give you any other choice
Before doing anything that ive suggested, wait till someone with more experience to come along........i dont want to be responsible for you fully bricking your shield..........just wanna give you an idea of what i think has happened
If worse comes to worse, if you have warrenty, get a replacement
Gd luck........remember, this is an analysis of your predicament of what i THINK might of happened, and what steps, i likely might of entertained.......after looking into it more thouroughly, knowing that i could get a replacement if it went downhill.........so your mileage might vary

I had something similar about... shield goes booting in recovery and trying delete some cache and keeps repeat and repeat
Hardware boot in fastboot / bootloader mode
Accessing Bootloader via Hardware
Unplug power from the Shield Android TV. *
Wait a few seconds.
Hold down the power button.
Plug in power
Count to three
Release the power button
You should see the bootloader screen.
If you hold it down too long or not long enough, it simply doesn’t work.
Restore Shield Android TV to Stock
P.s. Personally me I followed this instructions and kind of magically got it in bootloader mode. First done by instruction and then just gave up and pressed randomly and fastboot screen appear. Thanks God I had to done only once, if I would do again I wouldn't had patients
Good luck with this, hope you will get sorted
Here will be link about where I got instructions about hardware boot

Thanks a lot fro your help.
I was able to put the box in fastboot mode.
Since I'm not that expert can you tell me where and which rom I have to download (I have a french 16gb version of the box).
Then I'd need to know exactly what commands to performs (even a link to a tutorial is fine).
I really appreciate your help. It seems I can (hopefully) save the box.
EDIT: The fastboot command gave me a (not enough space) when I bricked the box. Is there a risk it could happen again while flashing stock? No idea how much space I have left on the box really.
EDIT2: I found this page: https://developer.nvidia.com/shield-open-source
and I'm downloading this rom called nv-recovery-image-shield-atv-upgrade2_1.zip
and Intend to follow these instructions: http://developer.download.nvidia.co...TV/Upgrade-2.1/HowTo-Flash-Recovery-Image.txt
Can anyone please confirm I'm doing right?
EDIT with joy : I followed all the steps using that rom and it seems everything worked. I reconfiguring the box now. Thanks for help.
basically the procedure I intend to follow is this part (please confirm it's ok):
To flash this recovery image to your SHIELD, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader. Get
DTB file name to use for flashing for your product(see below):
P.s. maybe Since past fastboot commands failed and I only flashed system from zulu99 I could skip the 'fastboot flash boot boot.img' command so if it fails again I still can attempt the fastboot process again?
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb <DTB file name>

You are on the right way with those links
P.s. You can do manual one by one entering or paste and copy those commands or (I'm doing) drag and drop file "flash-all.bat" on cmd previous opened there where you have abd/fastboot etc files and extracted RIGHT FIRMWARE (like shift and right click mouse "open command prompt here"
And after this all sit down and relax
Anyway you are on the right way.
P.s. Hope you download adb fastboot drivers somewhere from Internet !?!

Ok I'll just rewrite this post instead of starting a new one
Drivers are installed working fine.
Phone is unlocked.
So if I trwp phone at this stage it works and I can root it.
The issue seems to be once I fastboot the 4 files to the phone phone will not boot and hence can not root it.
I've redownloaded the fastbootl29 files still no luck
Am I missing a step is the fastboot stage just sending those 4 files to the phone no unpacking/setup or anything?
Anyone in Aus want to earn some $$$
Got past that stage it's now unlocked and sitting in fastboot mode.
Now when I send the command
Fastboot flash cache c:/1/cache.img
It just says waiting for device any ideas guys

Did you tried rebooting ur pc and ur phonte?
Got past that stage. Had to change the boot loader driver.
Load up the l29firmware in 4 parts use twrp then it won't let me root the device like it can't find it.
When trying to boot up the system it just won't boot. Now it's doing its erestore but notice it's looking for the cn firmware.
So this is what happened, I was on I MedroM v3, so I was there was a firmware in beta (the 7.0 update) so I've done it and now I'm stuck in a bootloop
, I flashed the Nougat recovery so it locked my bootloader
and removed TWRP so I can't even go to flash the old rom
again. I also can't get the product id now cause I don't have an OS installed, there's no way to pull it without it an OS. I have tried every existing method possible and nothing (including the sd
card method with update.app and bla bla bla)
So I can't flash files through fastboot It says " Command not allowed"
Can somebody please help me, I have experience with flashing and everything but I in my entire life have not seen that a phone company so big doesn't have a ******** flashtool
or some other way of recovering hard bricked devices instead of buying a new motherboard or something..
If somebody could help me I would be so grateful! Please excuse my language I'm very mad and frustrated, I need my phone for work and now I'm offline..
- Fastboot is available but the bootloader is locked
- No TWRP
- No OS Installed
Download a firmware you want, extract the update.app and put it in sd card folder. From the phone completely shutdown, press vol +, vol - and power at the same time hold it until the updater with percentage progress moving appears.. you should be fine after that.. ? i believe. Maybe try it. That's what i did on my case
No, It says "Software Install failed! Incompatability with current software version"
When I go to eRecovery t says that it cant connect to WIFI.
As I said i tried every known method and I can't get it to work. Spent my whole day trying to fix it, I'm out of ideas

I had the same problem, but with the L31.
First try to use https://www.xda-developers.com/how-to-install-twrp/
Then with the file i send you attached (MAF32)
- Fastboot flash boot boot.img
- Fastboot flash system system.img
- Fastboot flash cust cust.img
- and finally TWRP
After that i puted the first exctrated uppdate.pp in my memory card and with the "3 buttons" process i flashed it. Then i repeated the same process with the second one (http://forum.xda-developers.com/hua...droid-nougat-dev-build-huawei-t3488360/page33). After this finished, again with the 3 buttons i made a factory reset.
5 minutes later, it was working.
i don't understand how to boot to fastboot ? and where to get these img files i am really stuck here pleaase
You don't understand, In order to unlock the bootloader i need the product ID which you get by typing some number combination in the dialer. I cant get to the dialer cause I dont have any OS installed, cause the old was dirty flashed. So thats why i cant flash TWRP etc..
hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM.

Ok, this is what I would do if I were you. I would pick a rom in the development section, eg. RR. Then I would extract it and get the system image and boot image and fastboot flash them. To extract the rom, use SuperR's Kitchen.
Hope this helps.

Hi!
There is this but I haven't tested it: https://forum.xda-developers.com/android/help/extract-dat-marshmallow-lollipop-easily-t3334117
Let us know how it goes!
Alright so where i'm at now is basically the aftermath of a failed attempt to install a cyanogen unofficial rom for my phone.
I have a p9 lite VNS-L23 dual sim and well basically, i unlocked the bootloader and i rooted it with twrp and installed superuser using the srk tool. Everything worked fine up to this point until i booted into recovery, cleared cache and data etc to do a clean install and the install failed with an error code 7.
I thought doing a twrp backup before the flash was effective but because it didnt take any length of time, i sort of thought it definitely wasnt a full backup but i didnt pay it any attention and tried to flash it anyway since iv'e never had probs flashing anything with other of the phones ive had before which was my main mistake.
Usb debugging was enabled before trying to flash. I thought it failed because i didnt change my file system but i had no idea how to do that so i avoided it and tried to install a newer version of twrp to see if the rom would work with the updated version instead. When flashing the twrp img file, it asked where i wanted to install and i think i selected bootloader instead of boot cause there were only 2 options.
After than finished and i chose to restart in recovery, recovery never loaded. I was getting erecovery but that couldnt help me either. I was just stuck with no os and a phone stuck on the bootscreen. I tried to unbrick my phone by installing the update file for the international version firmware which i downloaded which was the only one not to fail after trying 2 others before it before realizing the error i was making. I read online that it would restore my phone back to ofw and that was great considering i had no os installed. Now, after the update, i think i reached like 100% then it went blank. I tried to wait a couple seconds to see if it was rebooting but nothing happened. tried all button combinations with and without the charger for varying lengths of time but no luck. I hear a sound when its connected to my laptop tho so idk if that matters. Its a bit frustrating right now and i have no clue how to fix this problem and i havent even had the phone for a long time. If someone. anyone can help me, id more than appreciate it
So far, nothing is responding to anything. No lights, no vibrations and i dont see anything when it conencts to my laptop, my laptop just makes the connected sound. I see Fastboot 2.0 detected but the srk tool cannot detect any emulators or devices :/ im so depressed at this point. More or less just bought the ****.
Sounds bad, try using the dload method and if that doesn't work you are ******.
What is the output of "fastboot devices"

its the dload method that has me in this mess. It didnt reboot from the upgrade and since then i think ive been in fastboot mode. I get a response with the fastboot devices cmd and i manage to flash the boot, recovery and system of the stock firmware but still no luck. Think my only option is to use dc phoenix but i cant buy credits for that

not getting to the upgrade screen with dload, the phone restarts but nothing on screen. I can use fastboot only to flash and unlock bootloader, check specifications but thats it. I flashed the stock image which is mm thru fastboot but no luck. I read that i might wait for my battery to drain since my battery isnt rly made to be removable. Can i still use dload without any on screen response?
Have you also tried flashing vendor, cust ... partitions ?

Fastboot doesnt flash certain img's such as xloader etc, no vendor img included inside the update but i doubt i'd be able to flash it anyway, but i flashed everything i was allowed to incl. cust, boot, recovery, system, cache, . Everything else is giving error: command not allowed. I've hit a brick wall so far til my battery drains or i take it to a repair shop which is i guess, last resort. Can't seem to find help anywhere on the internet, nothing returns anything to the screen.
Looks like a hard brick, take it to an official repair shop. But remember: unlocking the bootlader does NOT void the warranty.
