[Q] Bricked Wifi Xoom...

I tried to root my Wifi xoom with 3g files and bricked it. I have the system file that I could probably reload onto it if I could remount it, but right now it's stuck on the "dual-core" screen. I can force it into fastboot by hold the volume down button but my computer still isn't recognizing it. Is there any solution?
Edit: Nevermind, successfully restored...

Warranty? X)

Dead after the downgrade

First, sorry for my anxiety to solve this problem. Frankly I would not want to send to technical support, and stay up to 30 days without it. If anyone can help me I would be very grateful. Here the situation:
1) Install the normal sbf JRDNEM_U3_3.4.2_155-002_DEBLUR_SIGN
2) Install the nandroid 3.4.2_155-Nand.CEE_DEBLUR
3) Install the fixed sbf 3.4.2_155-Fixed.CEE_DEBLUR
4) To revert to Eclair, install the original uk sbf 2.21
4) And then, the result: the phone don't even turn on.
Already pullout the battery and the sim chip, and nothing happens. I connect to pc, and the led goes white, but nothing happens. I try to go into bootloader, but the phone don't even turn on. The battery is charged, about 80%.
Please, i'm desperate here. Already searched and keep reading, but find nothing that helps me in this case.

You are doing it the wrong way. Turn on the phone the rsd lite will recognise it. Then flash the 3.4.2 sbf back, then root it install recovery, restore 2.21 nadroid and flash a fixed sbf(without cg31 and cg39) not the full sbf. if you flash the full sbf your phone wont boot.

Thank you, vick33, but the phone does not even power on. I really would like to do this.

You wont see anything. The white led only will lit up when you connect it to the pc

ja tentou tirar a bateria fora, dai segurar o botão de volume pra cima, recolocar a bateria e ligar enquanto segura o botão de volume pra cima?
did you try taking out the battery then put it back while holding up the "Volume +" button and then powering up the device?

In desperation, I decided to connect the phone to the computer again, and that is worked, not even showing anything.
The normal would to show some texts, like ready to flash. But still worked.
Start RSDlite and flash the 3.4.2.155 again, and its ok. Thanks.
Marcio, já tinha tentado tudo isto, mas o Defy nem ao menos ligava, não acontecia nada, por isso achei estranho, e estava meio que desesperado. Mas deu certo, cara, mesmo sem aparentemente ligar o RSD reconheceu e "flasheou" o bichinho. Valeu.
Now, to go back no Eclair 2.21 and a nandroid backup of my rom (Claro Brazil), how to procede? I have only de UK Eclair 2.21, not a Brazilian SBF. I hope I do not **** now.
Thanks

You messed up..
Step 1 was a bad move.
Unfortunately there is no downgrade to eclair.
Revival:
Connect defy to pc, run RSD lite and flash JRDNEM_U3_3.4.2_155-002_DEBLUR_SIGN again.
Henceforth must have use froyo.

You can flash your Xoom with RSDlite 5.4.4 but you need to find the good sbf. file for this

Bricked MTCD KGL unit with Malaysk soft

Hello,
I downloaded the latest Malaysk software from the repository, tried installing it with the second method (from "System update") along with wiping flash.
Now this KGL MTCD unit is bricked, there is no response from it, aside from the buttons lighting up.
How to unbrick it?

can you get in to the Recovery?
Never change a running system if you are not knowing what you do

Yes, if you can get into recovery you can just flash. In the thread it clearly says that you have to get into recovery BEFORE flashing (because you have to flash twice due to partitioning).
Ask your vendor how you can get into recovery if the usual way (pressing power + reset at the same time, then releasing reset and pressing power a single time again) wont work.

Just get in recovery and use the Wipe data / reset cache option, then flash it again from recovery.
Reboot and enjoy

If I could get into recovery I wouldn't be posting this topic.
Recovery doesn't work.
What now?

TO get into recovery,
when it should boot up, press and hold power.
THen it will force shutdown. Next boot brings up recovery for me!

same here bro
the unit is totaly dead, cant go to recovery...

Like I said, I cannot get into recovery. The unit doesn't boot up at all.
Oh well, I'll just replace the motherboard.

for all of you with bricks. lets do some experiments
Can you guys hook it up to a computer and see if the computer can read it. If you can you should be able to adb the rom back.
http://www.rockchip.nl/downloads/
Make sure you have the drivers. If you can successfully read it then you can use RKTools or adb.

Fixed by removing the power connector and keeping power button pressed and restored power supply without ACC in order to establish usb connection with my laptop.
By using RK batchtool, I managed to restore my unit.

But I suppose that you loaded on RK batch tool the factory Mcu and firmware right?
Because in my case I can't find factory mcu and seller doesn't know to provide me the factory software.
So with batchtool what can I do?

Factory firmware failed checksum. So, I used Malaysk ROM. The latest version failed to erase screen, but, the previous one booted successfully. Initially I tries to use recovery and ended up in brick device. Only rear camera was working. The devices stacked to Malaysk ROM screen and no stand by if ACC OFF.

Hi there,
Trying to install Malaysk ROM on an MTCD-KGL unit, I managed to get it bricked. As in... no screen, no sound, no Recovery, nothing! Couldn't link it to PC, nothing. The reset + volume button combination did not work for me to enter Recovery. My screen was all dead.
So... After some research, I used "Rockchip Upgrade Disk Tool" v1.4 and the unit booted from the sd card inserted in the GPS slot (Guide here: http://wiki.radxa.com/Rock/SD_upgrading ).
In theory, the unit should have started automatically upgrade from the SD but in my case it presented an error requesting me to remove the sd card. After removal, the unit went to Recovery boot menu. Still a success.
When the Recovery menu appeared, I inserted an sd card with dupdate.img on it in the GPS slot and selected install from menu. Unfortunately, the unit kept saying that it does not find the sd card. Tried the other sd slot but same error.
Success came from USB port. One of the two from the back of the unit, not the one in front. I put the dupdate.img and dmcu.img on an usb stick and inserted in one of the usb ports from the back. The unit recognized the stick and started the update process.
Now the unit is working.
If someone is interested, I can provide MCU and ROM (version from October 2016).
Hope this helps someone.

Hi,
Before you saved your unit, did button light light up or not? I have same issues like you had, but unfortunatelly I can't debrick my unit. Could you provide me all files (links), which helped you to brought it alive, please? Thanks.

Hello! At my unit, yes the buttons light was on. There is a link in my post and also you can read here: http://forum.xda-developers.com/showpost.php?p=68717214&postcount=877

Reboot during using [FIXED + SOLUTION]

Hello,
Since a few OTA update, my phone keeps rebooting. Most of the time it was just after I validate the password unlock screen (so I removed it). Now it happen when I load an app like TELEGRAM (FLOSS) or Gallery app or during a skype call or any other app: it's random and anoying...
So the phone suddenly shut down the "google" logo appear then sometimes reboot normally sometimes keep rebooting in loop after 1 second specially if it's charging so I unplug it and it stops loopng.
Then if I can't boot it, I just load TWRP andpress BOOT SYSTEM from there.
I believe it's a software issue because it happened just after an OTA update (maybe around 4 updates ago)
I read 20 threads about reboot, they are very old and all talk about power button issue.
Any clue please?
Thank you
EDIT
Fixed by the following steps:
- put the original ROM with the software Nexus Root Tool kit which is super convenient to put the phone back to default
- do the Google account setup quickly (just put wrong information, ignore everything)
- do another full reset (from setting menu > backup and reset)

My 5x has been doing the same for about a week now. First restart was during a long run on a hot day. Have you had any success in fixing it? Safe Mode doesn't help, and I'm looking to move to October's update and wipe system cache. I'll let you know if that fixes things.

Result: still reboot... so it's probably a coincidence that since an update this phone reboot. I will change for a FAIRPHONE or try to fix it :

et en attendant, installer un logiciel pour neutraliser le bouton power qd le tel est allumé :
– Installer Volume UnLock : le déverrouillage du mobile se fera par un appui sur le bouton de volume
– Installer Screen Lock : le vérouillage se fera par une petite icone

I did another full reset (from setting menu) after I installed the original ROM and it's been a few hours that I'm not facing the problem anymore.... let's see

The October update didn't fix anything. It seems to do okay while plugged in, but I also noticed that the "USB supplying power to attached device" notification is on often, even with nothing plugged in. I tried cleaning the port. Fastboot still works, but it's hit and miss with USB recognition while powered on. My probable last recourse is to try the 4-core fix for BLOD issues. I'm on my second phone, and I don't know that it's worth it to attempt warranty again if a software fix can prevent the issues. Any thoughts?

Just to let you know that it's been now a few days my phone works very fine with the original rom

root?

Did you root after installing the original rom (which version, btw?)? Did you leave your bootloader unlocked?

No root needed. The last version provided by nexus root toolkit. Yes I left it unlock because I don't remember how to lock it back and I'm lazy to find the way to lock it! lol!
