[Q] Gnex wont boot. Cant flash from fastboot (too many links error)

CDMA GALAXY NEXUS> Hey guys, I was running Romanbb's 4.0.4 build earlier today. I clicked on a video (which may or may not have been on a porn site) all of a sudden my screen went all wacky. Where it was kind of fuzzy and running diagnal across the screen. I could only see part of it. I thought I might have gotten a virus or something because i have never had one of my devices do this before. So I immideatly rebooted the phone into recovery and wiped eveything including formatting system. I went to flash a nandroid I had of black ice and in the middle of flashing that my phone rebooted itself and stayed there (bootlooping at the google logo) I can get into fastboot and I can get into recovery about one out of every ten times but I cant do anything in recovery because the phone turns itself off insted of booting recovery most of the time (I have clockwork touch) When I do get into recovery without it turning off it reboots if I try to flash anything. It seems to be stable in fastboot (thank god!) but When I get it connected in Wugs Root tool kit and try to flash the stock image it goes through the motions and says FAILED on every step exept the first (which I believe is checking radio). It says ( error too many links) on the first two) and I cant remember the error on the last four but I have tried it a couple times so I can replicate it if needed. Can anyone tell me what to do from here? I really appreciate in advance!!! If this is a hardware error then I would like to get it back to stock to get it replaced. It is weird that it happened while running a rom. Its not like I messed up while flashing or anything.
ADB will recognize it in Fastboot. I already set all of that up when I rooted. when I try to flash the stock+unroot option on wugfresh's toolbox it errors out on every step like there is something wrong with my internal sd on my phone? Im wondering if I should try odin. IDK? Im hoping somebody who has seen this or had this happen before will save the day and tell me what to do.

lol why did you rush into CWM and start wiping things? you should have let it reboot and it probably could have been a one off..
you can try this http://rootzwiki.com/topic/14145-od...actory-odin-restore-402-with-radios-unrooted/

It is stable in fastboot but in cwr it is still geeking out
It still is glitching in cwr. most of the time it either turns off or reboots when I try to go into cwr. i can wipe but if I flash anything it freezes at the point where it starts writing to storage. I have never seen anything like this before.

I have now tried oden as well
It looks like it is a problem with the hardware. The phone is only a couple months old if that. So I really wish I could flash the stock image or at least get rid of cwm. but that is not looking likely. Here are a couple pics of odin showing the problem. Any guidace would be much appreciated. This SUCKS

Why in the heck are you trying to use Odin?

I can only get into fastboot and odin.
CWM wont let me do anything. it crashes and reboots into a bootloop if I try to flash anything. The poster above suggested odin. I dont know what else to do. Please help if you can!

Can you get a screencap of when it fails fastbooting the stock images?

yes
yes, give me couple min and I will post it. Thank you!
I guess I cant. This is all I get now

How are you attempting to access fastboot?

Vol + and Vol - and power all at the same time
Vol + and Vol - and power all at the same time from powered off
And oden was Vol - and power at the same time from powered off
Now no matter what I push it goes to the screen with the yellow triangle.

That screen says you (now) have a corrupt partition.
At this point, you must use Odin, which is unfortunate. What URL did you use to download the image? The current image in that thread was on multiupload.

during my rooting attempt I had a problem with the two vol buttons. It was quite frustrating. Keep trying them and try pressing the power button a fraction of a second sooner.

I downloaded the one later in the thread

there were a couple other posts right around the same time with it but they all were the same file name
I thought I saw the same files in the xda thread i found also
I used that thread because it is the one that the second post linked for me.

I pm'd you to ask how you could fix it. Just wondering if I could do it. I can follow instructions well. I have never had a problem and have been flashing stuff for a year or so. IDK what happened here.

I can't help but I wanted to share that I had a similar experience. I was bonne stock and clicked on a you tube video and my phone immediately shut down and tried to reboot itself, but only would boot loop. I had to manually reformat my partitions to recover. Sounds like your case might be even worse. Still don't know what my problem was.

Thanks. Any feedback is appreciated.

so you can't get into bootloader or odin screen any more? if so try using a Jig it works to get the phone into odin mode for me. i used the same usb jig i made for the captivate.

I got the same suggestion from someone else. I have to wait until radio shack opens in the morning and I will give it a shot. Otherwise, I went by verizon and they are having samsung send me a replacment. I would much rather keep this one if I can though
I tried flashing the stock image from fastboot and it failed though when I could get there, and I also tried flashing the stock image through oden when I could get there and both failed multiple times so I don't have much hope. I think something broke.
I am headed to radio shack now. Be back soon with a answer as to wheather I can save my baby or not.

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!

Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app

I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!

I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob

I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?

If they have parts on hand if not either a swap out or a sendoff

Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?

Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?

to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.

no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.

Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.

so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!

Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

[Q] :( HEEEEEELP! STUCK AT LG LOGO WHEN I TRY TO BOOT! But wait, there's more......

I have spent the last 3 days searching XDA & trying every possible fix, no luck!
Here's my dilemma.....
I have custom recovery, TWRP 2.6.3.3, don't know what I did after trying to flash something........ I wiped everything except SDcard by accident. Like a darn fool, forgot after backing up everything via computer, to put a spares on my SDcard. Sooooo, I tried restoring by using LG FlashTool..... Here's where my problems began:
1. I can't load into download mode, it sticks at the logo to enter download mode but doesn't connect.
2. I tried ADB Sideload, sticks at "STARTING ADB SIDELOAD FEATURE.........."
3. No matter what mode (including Fastboot) I try, just won't connect to my computer the way I need it to. (*ALL DRIVERS HAVE BEEN REINSTALLED NUMEROUS TIMES, STILL NO LUCK.*) When I look in DEVICE MANAGER, it shows in "OTHER DEVICES" as "LG-LS980" (*Which is a good thing right? *)
At this point i'm at my wits end...... I tried to HARD FACTORY RESET, but didn't go thru. I'm afraid that if I tried it again, I could cause even more damage.
I've been without my phone for days & I'm about to go crazy if I have to pay LG or Sprint again for another phone!!!! I'd rather use my $600 on something else.
PLEASE TELL ME SOMEONE HAS FOUND A WAY TO GET AROUND THIS!
I've searched just about every forum & tried different methods.

Forgot to add that every time I power off from recovery, I get a the message about my device not being rooted, would I like to install..... When I swipe to install, nothing happens. Just powers off.

So try this...
Push the power button to turn the device on. Let it sit.
After you know that the g2 is on and trying to do its think, Press and hold power buttton, do not let go. It will force turn off the phone, but it will start to turn back on, if you keep holding the power button till it shuts off for the second time, you'll be set and the device will be fully off.
Have Lg Flash Tool open, make sure you have manual mode on and you point to the right dll and right tot file, could be zv7 zv8 or zva.
Click the arrow to have the flash tool biin check the files. when that is ready, do this next part fast. Plug in your phone, and immeditaly press and hold Volume up and Power. Download mode should appear.
and you should be good from there! If you try to enter download mode by using volume and up without the cable plug in, you'll hit the factory reset menu which is tied to the recovery, it'll do nothing, only take you to recovery. I hope this is of some help!

Edit:try new boot loader or system flasher via twrp
proplem i faced is one button which used to enter recovery is damged
Flash stock Ignoring the unmonted ianot able to be mounted then change system partitions u will be able to mount
Enjoy

[Partially solved][Q] GT-N7100 download mode problem

Hello,
It's been a while since I last stepped foot in the xda forums as I've been happy with stock, however when kies pushed the 4.3 update to my Note 2 I've started having problems - my phone will not sleep. After 2 min timeout the display turns off and immediately turns itself on again. It then goes into a loop where it turns off and on again every second until I unlock it. This is playing havoc with my battery life (I only get about 6 hours from full charge now). I've tried disabling any setting that might cause this (like smart stay etc.), I downloaded wakelockdetector (doesn't detect anything), I've tested my sensors and sleep mode with #*0*# (sleep mode has the same problem here), and I've done multiple factory/hard resets (x5).
I want to go back to 4.1.2 because this problem only started happening with 4.3 except now I have a different problem - I can't get download mode to work so I can't flash any recovery/firmware. I get the download mode screen up via the usual 3-key method, however once I'm there it seems to disable my volume keys because they stop working. I can get into recovery mode without any problems and the volume keys work fine there, but once it loads up the download mode screen and prompts me to press vol up to start or vol down to cancel, no matter what I press nothing happens. I have to hold down the power key to reboot.
Does anyone have any idea why my Note 2 is so broken?
Would really appreciate some expert help here. Thanks in advance.
Other stuff I've tried: I've tried with and without my SDcard. I've tried formatting my SDcard. I've tried taking my battery out for 5 mins and then go straight to download mode, but still my vol keys won't work.
I got kies to do a firmware reinitialisation which downloaded 4.3 again and flashed my phone a second time but still the problem persists.

I guess I have no choice but to put my hope in Samsung support. It's a real kick in the teeth that the nearest official support centre is an hour and a half away from me. I think this will be the last Samsung product I buy.

How?
Forgive me if I'm wrong, but with 4.3 comes with knox and a locked bootloader. I can't load philz or twrp zip from recovery because it errors with an unsigned message and since I can't access download mode I can't use odin.

Shut down your phone. pull the battery out. connect your tether cable to the phone and USB to computer. start oden, put tar file in PDA box. don't change any other settings. Put your phone in download mode by pressing both up/down volume buttons (not Power) and insert the battery. once in download mode, click on Start on oden. As for the bloatware, you are going to get whatever apps that are in the tar file. I think Some of the bloat has been removed. Not sure what, but it seems most of it is still there. I think DriveSmart is gone

These don't appear to be the correct instructions for a N7100. Well, thanks for the bump anyway.

Hi!
Did you try to flash with mobile odin? It might be the solution if you can't access to download mode (which is weird by the way...)

I have same problem
i just flash new bootloader kitkat
"Bootloader If you have MJ5 or later bootloader then no need otherwise you have to apply Reboot and wifi Fix from post #3 above
You can get idea about current bootloader with info application
If You are not worried about warranty then I strongly recommend to flash Kitkat bootloader.
Here is Kitkat bootloader from N7100_ND3 "
and now my phone was on and it will stuck on samsung logo...
i m also not able to install stock rom
help me to downgrade 4.1 old bootloader.

Thank you!
Mobile odin worked. Got the pro version to thank Chainfire. Also managed to get root thanks to Kingo and I'll be donating to them as well.
Unfortunately even after flashing CM10 it hasn't fixed my sleep problem. Well, maybe I've got a hardware fault after all...funny that it coincided with the 4.3 update. I guess I've voided my warranty now but on the bright side I've finally ditched Samsung's bloatware and stock android. Here's hoping I can find a fix.

[Q] Nexus 7 suddenly bricked ?

Hello all, so yesterday I went on my tablet (Nexus 7 2013 WIFI ver.) and browsed the net a bit and went to sleep. I recall having around 30% battery power. This morning I wake up to an apparently flat battery (power button didn't turn on anything) so I just plugged it in and did something else. After a while, I took my tablet and started it with the power button. However, it got stuck on the Google logo and never fired up anything. I've rooted the tablet quite some time ago (months) so the cause is not from there.
Things I haven't recently done:
Installing an app.
Rooting or flashing anything.
Updating an app.
Things I have tried doing to fix the problem:
Booting into FASTBOOT then trying the recovery mode = still stuck on the Google logo.
Booting a custom recovery image using Wug's toolkit = frozen at the team logo (TWRP) / black screen (CWM).
Flash Stock + Unroot (Soft-Bricked/Bootloop) = FAILED (flash write failure).
So now I'm really stuck and desperate to make the device work again. I've been reading all day long and trying all sorts of solutions to no avail. And it seems far-fetched to me for a device like this to just instantly brick itself without any reason at all.
Can anyone help me with this case ? Or does anyone has any idea what just happened to my tablet ? :crying:
EDIT: I'm afraid that warranty might not work as the device was unlocked and rooted so it's the last solution for me.

No one has any idea what happened to the tablet and how to fix it ? I've tried doing some more flashing but to no avail. It just refuses to flash and keeps failing to write the files.

I think you need to leave out on the charger for 1/2hr without doing anything with it. You are probably using what little power it has charged by trying to reboot it, etc.
I had to do that once and it did the trick.

There is no reason you should not be able to get in to recovery (power and volume down).
You could call Motorola. They have good tech support.

The exact same thing happened to me. I rooted it months ago and haven't changed a thing since then. It just froze up a few days ago. I restarted and it just gets stuck on the google screen. I can get into the bootloader, but when I try to go to recovery, the google screen comes up and won't go away. I've tried every method I can find for flashing the stock image and absolutely nothing is working. I just get stuck on the google screen.
Please update this if you find a solution!

Do u guys have the most up to date version of whatever particular recovery that you're on?

Yep. I've flashed the stock recovery multiple times to no avail. :/

If you can't get into recovery or flash any images it sounds to me like a hardware failure. Bad memory maybe? If you've tried everything then RMA to Asus before the one year warranty runs out.
Have you tried to see if your computer sees your N7 by typing fastboot devices if you have the sdk installed?

Not what I wanted to hear, but you're probably right. Thanks :/

I was to slow with my update. Does your computer see your N7 with fastboot?

Yes, I can get into the bootloader just fine and I can use fastboot. I go through the flashing process and the command prompt says everything flashed successfully, but when I restart the device, it hangs on the google logo. The same thing happens when I try to boot into recovery.

If you fastboot flashed the factory image and can't boot up then it sounds like a hardware problem. Out of ideas, sorry.

I'm not sure what happened, but I just ran this little utility again (I've done it many times over the last week or so to no avail) and it actually worked. Hopefully it keeps working!
Thanks for your help!
