[Q] How to repair a bricked Xoom

Bricked my xoom with wrong imagefile when rooting it.
I would like to know which part, if possible, to replace to get some life in my xoom. I'm stuck at the Motorola logo screen with "Starting RSD 3 mode" or nothing. Can't connect to it with RSD-Lite, ADB or fastboot. I cant connect to it from any of my computers. I have a Linux 32-bit and a win7 64-bit.
So,this is my question.
Can I replace something in the tab to get access to it? Something that comes "preloaded" with the software that I need to communicate with the device using ADB or fastboot? I think, if it's possible to do that, I can flash new imagefiles found in this forum to it.
To tear it down I found this guide:
http://www.ifixit.com/Teardown/Motorola-Xoom-Teardown/4989/1
What do you think? Is it possible? And, if so, where can I find that piece of hardware? Motorola company spareparts? Thats the hardest I think.

I have the exact error as you do! How do we unbrick this error???

I think it's impossible without sending it in for replacement or repair. It would be nice if someone who repairs it tell me what they did when they repaired it. If it's a hardware replacement or some kind of "forced" flash of new software. I hope they have some software tools that we in the community doesn't have. If so, it shouldn't be so expensive.
My problem is that I bought it from a person who bought it from Best Buy in New York. I don't have any warranty because I'm not the one who bought it and here in Sweden they won't repair it because they don't have a service-agreement with Motorola yet. So I have to do it myself or throw it away.

Contact your nearest Motorola office directly, they didn't ask for any paperwork to replace mine.

Really lucky, I managed to get a Xoom with a problem that no one has seen or heard about

I had same problem. Try power, vol- and vol+ all at same time. When it comes back on do power and vol -. that should put you back to fast boot. It worked for me anyway.

Yes I did a fast "read-thru" of this thread. My problem is different. I can not reboot into fastboot mode. Only RSD 3 mode, and RSD-Lite can't see it. I tried to flash the 3g sbf file just to see if I could restore the fastboot mode and check if RSD-Lite could do anything at all. Nothing happened. That's why I want to learn a little about hardware and replacement of hardware "things". I think that's the only way for me to fix it.
I'm thankful that you are trying to help but all threads are about fixing things with fastboot and fastboot is DEAD on my xoom.
I am searching for a way to restore fastboot.

I feel STRESSED OUT after bricking my Xoom. I bought my Xoom with a $200 off rebate, which is $400 total from costco. PLEASE, someone help us with the RSD mode 3 error!!!!!!

Same problem
Hi jai134,
Just wondering if you had any joy with hardware replacement or some other solution? I think my problem is exactly the same as yours. It's RSD mode 3 or nothing! Windows and Linux can't see the device, and no combination of button presses seems to do anything.
The guys at #xoom on freenode very kindly spent a couple of hours trying to help me out last night but to no avail... it turns out I flashed a zip instead of a boot.img using fastboot.

Thanks. That sounds like what I'm looking for... I refuse to believe this one can't be salvaged!
I'll give it a try, and will let you know how it goes.

Hooray!
It worked! My Xoom is unbricked. I made a scary looking factory cable which allowed me to flash with fastboot. My experience was exactly the same as post 41 in the following thread:

Here's one end of the cable. The other end is just a regular type A USB plug.

I soldered some staples to the cable and attached them to a micro-usb male breakout board I got on Amazon (see post 43 of the thread linked above). I'd advise covering the connections and staples with electrical tape. I didn't have any handy and consciously decided to take the risk, but any contact between the staples could have fried the USB ports on the Xoom and/or the computer. I'll be taping this up and keeping it on standby in case it's needed again!
Thanks very much for your help cam30era, and also the guys on IRC at freenode, especially Kas and Solarnz.

I just walked someone through this error yesterday, after about 2 hours we recovered his xoom. Don't forget to stop by the xoom irc channel on freenode, you would be surprised the stuff we recovery from in there.

Anyone got a busted phone?

I'd like to do some research on an Infuse 4g. If anyone has a busted phone, I'd like to do some reverse engineering on it. The work I do will benefeit the community and it will help out greatly with porting other OSs and working with alternate bootloaders. In order to get the information about the OM pins, I must remove the processor. I do not have the ability to replace the processor afterwards. The board will give it's life to help others.
It does not matter about condition.... won't turn on, water damaged, screen cracked, case broken.. I'd like to destructively examine the mainboard for component identification and location.

If I had an extra $125 lying around to pay the insurance deductible (soon to be $199...), I would gladly 'lose' my phone for the cause.
Otherwise, I've seen a couple on craigslist, but the cheapest was $75 due to "toilet damage".

I purchased my phone outright for $600. It has no insurance and a few months of warranty. I would not recommend anyone participate if their phone is under warranty or warrantable.
If you have an extra device around, I'd like to document it and make something for everyone to use as a reference for hacking their devices.

That would be awesome! I will keep an eye on eBay and craigslist for any dirt-cheap non-functional Infuses. I'd probably be willing to pay up to $25 for a cadaver.

Bump, we've got a bootloader hello world running on the Captivate. I'd like to get this up and running on an infuse. It won't be long until we have a download mode for our processor.
Once we get download mode, we will be able to run a tethered boot of just about any ARM compatible operating system.

Bump. This means unlocking the actual bootloaders.

Just curious as to what other OS's would actually be ported to the infuse and what the actual bootloader unlock could do

It works like this, you do the hardware modification once, and you can unbrick your phone under ANY circumstances like this:
It enables uploading of the Hummingbird Interceptor Bootloader (HIBL). The HIBL enables uploading of unsecured code. You can upload bootloaders or kernels, or just about anything with the HIBL.

So.. your telling me (watched that video), that you HARD bricked your phone, did a little hardware, and brought it back from the dead thanks to the HIBL? You sir, are a god amongst tech folk.

Yes. I DELETED the Primitive and Secondary bootloaders totally from that device, used Ultimate UnBrick Resurrector to upload Download Mode to the device, then used Heimdall One-Click to reload firmware.

Dude, that would be SO helpful.
If you can, do it, the Infuse will be useless after that though (Processor removed, from what he's said), but I think you can just warranty replace it for another after that.

So this is what we need to get other OS'es on the Infuse?
By other OS'es, you mean like the HD2 that has WP7, Android and everything?
OR does this mean better ROM's?

Welcome Back Infuse!!!

For the last three months, since I softbricked and brought my Infuse back to life with GTG's Ultimate Unbrick I've been fighting the poor performance and sluggishness on my Infuse and cursing the day I rooted it! Today I started uninstalling apps right and left and BAM! We Have Performance! Sometimes, it's the simple things stupid! You've loaded too much crap on your phone!

No no you have it all wrong! You didn't have too many apps you simply need a bigger phone.

Not if it's no longer talking to my PC via USB in Download mode that I'm aware of.

Have you tried different USB ports, and or a different USB cable? I have three stock Samsung cables and only one will transfer data.

So just to be clear your getting nothing at all, no Samsung logo, or boot animation? How 'bout a battery charging logo?
If you getting none of that definitely give Rickrocks013 sugestions a try. Take the phone apart and clean the power button contact points and make sure its functioning properly, and get a good USB cable (the ones that come with the phone are about as cheap as they come) If you currently have a USB cable in the condition that two of mine are in (no data connection) download mode would be impossible to achieve.
My understanding of the Infuse is it's near impossible to brick, sometimes a bit of extra effort may be required, but with developeres like scott working to keep software updated for our device, the effort is well worth keeping your device running, IMO.

No I'm getting a screen with a phone and a computer with an Exclamation mark inside a triangle between them and it won't connect to the PC anymore and it won't boot it just comes back to that screen no matter what I do. Geek Squad couldn't get it into download mode either.

Have you tried a new USB cable and tried different USB ports on the computer?
What type of computer are you using and what operating system is it running? If your running a windows variant try re-installing the samsung kies drivers. You could also install Linux on a small partiion, ultimately having a Linux based OS (as a second if your not comfortable leaving windows) is a great thing to have, if your going to be doing a lot of tinkering with android based phones, it's nice to have as a rescue system once windows goes down as well.

I just don't think I have the brain power anymore...

I will gladly mail it to someone who thinks they can fix it. I've already switched to Straight Talks Samsung Galaxy Centura with ICS. Sadly, the new phone has no GPS. I don't plan on rooting again. I've been having health issues lately that include lightheadedness, dizzy spells and just plain old fuzzy thinking so frankly I think it's currently beyond my ability to fix what I've broken.

Using the correct USB cable is what allowed me to screw up the phone in download mode. I was using Ultimate Unbrick with Odin but it appeared to be stuck on establishing communications. I rebooted the phone and that's when it went to the no longer talking to your PC screen. the new Samsung Galaxy Centura sees the PC just fine with the existing USB drivers. I'm running Windows Vista Pro 64 Bit.

In case anyone doesn't understand what I'm talking about, here's what my phone now looks like:

Now that I at least have a working phone again I guess I don't mind tinkering with this if anyone thinks it's not truly hard bricked but so far I'm finding no love trying to get back into download mode or getting my PC to see the phone with the above image on the screen.

Where did you get that cable? My guess is that it's still a bad one.
That screen is another form of download mode. That screen always comes up after a bad flash via Odin or heimdall. Try buying a new cable, then keep trying different usb ports. I've had the issue of Odin getting stuck a bunch of times and gotten that screen. Finding the right usb port and cable has gotten me out of that mess every time.
There is a chance your current cable might work after enough tries, but you will want to blow your brains out trying. It's easier to just get a new cable. A good flash of Odin should take like 3 minutes. Just start over if it takes longer.
Good luck.

I had never seen that screen but figured thats what it was from his description, glad you could confirm. BTW I agree with the assessment of a bad cable or port as your primary issue.
Just a thought, you mentioned using oden, have you tried using the heimdall back to stocks? You need to have Java installed but they work really well.

Thanks for the offer but I shipped it UPS to the Samsung repair center on Monday. They got it today so hopefully I'll have it back within a week.

Samsung ROCKS!!
Not only did they pay for shipping, they didn't charge me a dime to fix the mess I made of my phone! And I was totally honest and upfront about breaking my warranty by rooting my phone from the get go! Talk about Customer Service above and beyond my expectations!!!! :victory:

UART port found on Fire HD6

I found the UART port on the Fire HD6. It's on the JDEBUG pins. Will post more info later. For now here is a demo:
UART connection layout image
Normal Boot Log
Fastboot Boot Log
My infinite adb reboot script
Edit: RX and TX ports found on the fire HD7 5th gen: http://forum.xda-developers.com/ama...bootloader-unlock-ideas-t3289721/post66265656

great find !
there should be some interesting stuff being output via UART

I realize that I'm necro'ing a 15 month old thread and for that I apologize. However, I've found NOTHING else on the web regarding this topic, hence the necro'ing.
At any rate, I recently bricked my Fire HD 7 (4th Gen) after flashing the 5.2.0 stock recovery zip. It's bricked to the point of having zero signs of life. So, my questions are:
1. Did you ever locate both Tx and Rx pins on the board?
2. If I can successfully communicate with this board via my TTL serial adapter, is there any chance of a successful recovery?
I realize that the effort required to do this is not justified by the current value of the device. However, that is not my concern. I'm simply in it for the challenge.
Thanks!

The first question is, can you establish any communication with the Fire HD 2014 preloader when it's bricked ??? If you can, that'd be quite exciting !

Man I have been trying for hours now. I'm a bit disappointed. I created a whole breakout board setup for what I thought was the uart port. I still have only found the TX.

I know this is a really old post, so I might not get a response, but did you ever figure out the pin for RX? Have a HD6 that all I get is the amazon logo at boot. the how to that I have used to unbrick before does not work because this happened after the update to 5.6.0.1. Wondering how to go about communicating through the JDEBUG port. I used gtkterm like I do when configuring cisco equipment. Are there certain setting for the port to communicate properly. Really trying to bypass the read and write block through the usb that seem to happen with the update.
Update- Found half my answer serial and UART are not really the same thing. Looks like I need a USB to UART cable.

Personally, I'd recommend you go with this if you're simply trying to unbrick:

I'm pretty sure that it will require that you fully brick it first though (i.e. No Amazon logo, or any real signs of life)
However, if you're getting to an Amazon logo, you should be able to boot to recovery, no? If so, you shouldn't even need to use that aforementioned unbrick process.

I know this is a really old post, so I might not get a response, but did you ever figure out the pin for RX? Have a HD6 that all I get is the amazon logo at boot. the how to that I have used to unbrick before does not work because this happened after the update to 5.6.0.1.

That is the previous unbricking method I mentioned. Worked really well in the past but does not work with 5.6.0.1 it blocked the reading and writing so trying to get around that. It started with trying to flash from cm11 to FireOS and the recovery got lost, so no recovery. It has spiraled down from there. Now I cannot even get to the boot loader because I cannot get into adb. I figure it is a lost cause and already have a replacement, so I figure what better time to learn. It is already beyond broken.

Just curious... what if you tried a fastboot cable? I know the fastboot cable is not supposed to work with this device, but I wonder if it makes any difference when there's no recovery installed.
Also, my experience with UART hasn't been super positive. It works, but there's a nice learning curve associated. Subsequently, I found it rather easy to destroy a couple of bootloaders.
Hopefully, you learn quicker than I.

Thought about the fastboot cable. I know it is possible to DIY so I might try that or might just buy one when I get around to getting a 1.8v UART USB board, I think that is what is needed. Not in a hurry now as I just bought a lot of 2 HD6s off ebay that where listed for parts and they are both working fine. Already rooted, TWRP, and CM11 on one as that how the one I destroyed was setup. Hopefully I can get the other one on FireOS 5 and build a device tree and try building CM12, unless I am told that would be impossible. This whole thing started because I wanted to get the headphones working in CM11.
Would appreciate any information you could share on UART. I was just going to try the unbrick ISO through the UART port.

Most of my experience with the UART port comes from trying to unbrick wireless routers. UART is simply the serial interface that lets you communicate directly with the board. Once you know which pins are which on your board, getting it connected is relatively straight forward.
However, after you get it connected, this is in my experience where things get messy. There are many different environments in which you could find yourself once connected. Depending on the environment, you may or may not be able to get decent help from Google as to how to procede.
In general, what you're doing with UART is writing directly to the board's memory. This allows you to possibly overwrite the bootloader, recovery, etc.
What I can say is that the ISO will likely do you no good via UART. It's possible that you might be able to extract some info from the ISO that you could use in contructing your UART commands.
If done correctly, you could get your device back. If done incorrectly, you might have a true brick.

Need help same situation here

[Q] Replaced motherboard, now it's not charging!

Hey everybody! As the title says, I replaced the motherboard on my SM-G920V with one from my wife's old S6 (also 920v). She thought it'd be fun to throw it at me when she was angry, and shattered both front and back glass. BUT ANYWAY... After I finished installing everything how it's supposed to be, I started it up and was so happy to have my S6 back to OE2! My only issue now is that it won't charge, yet will recognize a charger. I haven't been able to connect it to a computer, because mine was blessed with a lovely RootKit/netbot that took over every aspect of my machine. So if any of my hardware people could help me out, that'd be great! What could I have done wrong?!

Maybe just replace the charging port and everything will be right. good job on switching the motherboard, it is really hard to do anything with this phone, I just sent it to samsung when my touch wasn't working, eventually paid 40$ but screen is like 300$ , they said my touch connection to the motherboard was bad. Anyway, I recommend you to send your phone to there or switch alone your charging port, good luck

What was your reason for changing the motherboard on your phone?
Sometimes you have to match the right Rev.# Hardware for the charging port. So basically change out the USB pcb board with the one in your wife's phone and check does that work.
To fix your rootkit portable superanti spyware software or kaspersky. Easy fix...

My reasoning was simple, and purely justifiable: ROOT! Mine did the upgrade with the patches, so I lost root. I figured "Why not?!" I'm pretty good with computer hardware, so I figured I'd try my luck with phones. I will definitely try that when I get home from work, thank you!
And as far as the RootKit, I tried a couple things, but I think it took over my flash drives too. I'm definitely gonna get the machines (yes, all 3 of my machines got it) repaired, but I have more important things right now. Like my phones and my new-ish baby and food. Can't forget food.

Let me know if you were able to fix this, my galaxy S6 edge is not charging anymore, only slow charging (usb charging speed) which takes more than 6 hours for a full charge, i even tried some replacement usb boards and they didn't fix the issue, so i don't know what to do anymore, and i don't want to send it to samsung.

Did you try chnaging the USB cables, chargers etc. Also sometimes dust on the USB port can cause a loss of connection. This is a old trick you could try and still works very well. Get an old toothbrush (make sure its clean and dry) and brush any dirt off the USB port connection

I still don't understand why you changed the motherboard. Could you explain!? You trying to say that your (original) phone upgraded to 5.1.1 and you lost root? So you decided to change the motherboard.*
Did you open both phones and see if the USB motherboard is a different version on either phone.
As I said with the rootkit download superanti spyware portable or kaspersky will fix everything. Easy!!
If you need a hand with that rootkit I will help you

BOOM!!!!

It did the upgrade to the patched 5.0.2 and snatched root away from me. I had my wife's broken one laying in a drawer, so I figured I'd try swapping.

Yes, I did. And they are completely different. But in looking at my original, I snapped the ribbon connecter. Whoops. So them I thought about all the stuff that on the back panel (see image). So, what i ended up doing, was a swapping out everything that connected to the motherboard from the back panel. Power button, Volume buttons, and the speaker/mic hardware. And I'm proud to say, IT WORKED!!!!!
So, thank you for pointing that out to me. I really do appreciate it.

I appreciate this as well. If I need some help with it, I know who to contact.

You upgraded your original phone? As in you got a custom ROM which was pre-rooted? Is that what you mean? This still doesn't explain why you would change your original motherboard with your wife's one. I still don't understand why you would change motherboards.
Why didn't you just Flash TWRP and respected BL and modem for your phone. Then Flash a 5.1.1 Rom for your phone. Android version 5.1.1 seems to have solved all the problems that 5.0.2 has. You wouldn't have needed to change any motherboard then.
So everything is working now that's good.

The Verizon bootloader is locked, first off. And second, the patched 5.0.2 that they released OTA made it to where you can't downgrade. The original 5.0.2 was rootable. Not the patched version. Anyways, problem was solved. I'm working on my laptop's issues now.
