cwm bootloop

same here, cwm bootloop after installing latest xenonhd
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
Perhaps to clarify...

I was performing a routine ROM install [XenonHD], then rebooted. So, as happens sometimes after a new install, the N7 entered a bootloop. Okay, no problem, power button + down to get back to recovery mode...except instead of recovery mode, I find myself in the same situation as documented in this thread [splash screen and CWM bootloop].

Maybe if we can find something in common that causes this situation, then perhaps we can prevent others from falling into this trap...

Cheers, Shab.

how much damage can a Rom do?
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
To be honest, untill a few days ago, I would have said not much...but here I am looking at my Exus 7...and this is the first time I've lost a device to what appears to be a software issue [I have been involved in the computer industry as a systems engineer for the best part of 25 years].

Anyway,

I would love to get to the bottom of this problem, and will endeavor to achieve this...

RIP my lovely grouper...

It happens to me too. After flash XenonHD, cwm bootloop :crying:

Dose this happen with twrp
[Nexus 7 Q&A, Help & Troubleshooting] marcomarinho:
Anyone tried to send it to the warranty?
[Nexus 7 Q&A, Help & Troubleshooting] iceandfire:
Okay did anyone notice everyone is having the problem with cwm?

Anyone with twrp or philz facing the same?
[Nexus 7 Q&A, Help & Troubleshooting] USBhost:
That's the first thing I noticed!

Seeing what a ROM can do bad

I'm now scared to flash ROMs now.
[Nexus 7 Q&A, Help & Troubleshooting] marcomarinho:
Be careful with the recoveries, not with the ROMs
[Nexus 7 Q&A, Help & Troubleshooting] USBhost:
OK ty

So The problem is on cwm?

Not the ROM

But how can a recovery stop you from booting into the bootloder?
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
For what it's worth, I don't think this is a rom problem...Earlier in this thread, it was mentioned that this issue happened during a paranoid install. I just feel that the rom is not the problem, I think it's a combination, or sequence of events [ I have absolutely no proof of this, it's just a gut feeling]...

BTW: The battery has now run down, and I am now able to interrupt the boot sequence after connecting the USB cable. Unfortunately, after various button combos, it still ends up in the boot-loop. Will persevere...

Shab.

Warranty

Well, I tried to. Google actually doesn't have a problem with giving you the warranty on any issue. Which is much better than other companies. So if your tablet is rooted, or any custom ROM is installed, they are still willing to give you warranty.

But there's a catch. All you need to do is put it back into factory conditions, and then they are willing to come and pick up the device.

But for users suffering this problem, it is impossible to do anything other than watch the sad bootloop play out, over and over again.

So for us, the best choice is to replace the motherboard, to revive our wonderful tablets. Check on eBay, they're reasonably cheap, and easy to fix.

If you want any help in fixing the motherboard check this guide :)
[Nexus 7 Q&A, Help & Troubleshooting] jt.one:
wow i come back to the community to look for a new rom to flash onto my nexus 7 and i stumbled upon this!

really scary stuff. very sorry to those who lost their devices.

is it truly CWM recovery that is the culprit?

It seems to be

[Nexus 7 Q&A, Help & Troubleshooting] jt.one:
that sucks!

i also lost my galaxy nexus to cwm recovery sometime ago, (albeit it was slightly my fault but still) and have been too scared to use cwm recovery anymore. strictly stuck with twrp from then on.

Has anyone tried fixing there n7 with JTAG?
[Nexus 7 Q&A, Help & Troubleshooting] marcomarinho:
What is it?
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:

Have looked up JTAG, but I don't quite see how this could resolve the problem [apologies if I seem a bit dim]...

Many thanks,

Shabby.
[Nexus 7 Q&A, Help & Troubleshooting] USBhost:
JTAG sends commands directly to the CPU

And with that maby there's some way to fix this problem

Like force the CPU to boot to the bootloder

But I don't know if the nexus 7 has support for it

Or even know how/where to enable it

Maby n7 has its own version of JTAG?
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
Thanks USB...I'll do a bit more digging [again!]...

I know I could go out and buy a replacement tomorrow, but I now NEED to resolve this, as maybe I have previously mentioned!..

Anyway, thanks for all the contributions & help...

Shabby.

---------- Post added at 03:19 AM ---------- Previous post was at 02:55 AM ----------

From what I can gather, as I mentioned earlier in this thread, I don't think this is induced by a ROM install.

However, it would be interesting to ascertain if this issue is confined to CWM...

Excellent ROM BTW...

Cheers,

Shabby.
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
On a separate note, is it essential that I use the original cable that was supplied with the N7?

The only way to fix it is change the logic board.

I sent my Nexus7 to a informatic store, and they told me that the problem was an switch button that is broken. They'll replace it and then see if works :fingers-crossed:
[Nexus 7 Q&A, Help & Troubleshooting] RexValkorie:
This board right?

But I only found the mainboard for 16GB version while my N7 is a 32GB Wifi version :(
[Nexus 7 Q&A, Help & Troubleshooting] hheegg:
Change mainboard, got it at ebay for 39€. The only positive thing, I made an upgrade from 16gb to 32gb. No difference with this boards.

I will stay with stock rom now, is not to bad.
[Nexus 7 Q&A, Help & Troubleshooting] Captain Sweatpants:
I was unable to replicate this with twrp so it must be a cwm problem. I had a spare motherboard so wasn't to worried about a hard brick
[Nexus 7 Q&A, Help & Troubleshooting] marcomarinho:
Search on EBAY
[Nexus 7 Q&A, Help & Troubleshooting] SHABBYLEA:
So perhaps this a CWM problem...Although it would be great if we could have more corroborative evidence from other users.

same boot loop happened on my n7. following all the advice on here I was able to bring it back to life for 40 bucks via ebay for a new motherboard. oh well, that was fun. Same rom installation and same error as noted here already. im on cwm if that means anything.

Be well.

[Nexus 7 Q&A, Help & Troubleshooting] acontica:
I got the same problem after flashing XenonHD on my grouper,

I had checked for two weeks and finally I came over it by this way:

1- make sure you have proper ADB drivers on your windows

2- create an executable batch file (eg. boot.bat) with below contents:

:loop

adb reboot-bootloader

goto loop

3- connect Nexus 7 via usb to PC

4- run boot.bat

5- power it on and press Vol - key several times and with erratically, keep trying. it worked for me.

6- after unknown cycles of recovery bootloop finally it enters to Fastboot mode.

7- flash your recovery by desired one (I recommend TWRP) and run your recovery and wipe everything and flash a good ROM

8- good luck
[Nexus 7 Q&A, Help & Troubleshooting] RexValkorie:
I will try it tomorrow and I will respond later.

Thank you in advance. :good:
[Nexus 7 Q&A, Help & Troubleshooting] RexValkorie:

Finally exited CWM bootloop on Nexus7 - thanks acontica!

================

Thanks - I keep checking to see if there is a solution to my bootloop problem and I was hoping someone would come up with this :D (I'm too braindead to write that batch file).

Finally entered Fastboot with your boot.bat, flashed TWRP, and all is well. Thanks again!! And if you ever come to India, I'll buy you a beer ( or more)

The bootloop is due to CWM not checking for a compatible bootloader. Apparently flashing OTA or Stock ROMs updates the bootloader, but not custom ROMs, so you have be sure that you have a compatible bootloader. I remember TWRP (before the bootloop gave me an error and did not flash the custom ROM (I think it was PA), so I flashed CWM and it attempted to flash the ROM without checking and got into a bootloop. (That was in 2013 !).

Thanks!

[T-Mobile Samsung Galaxy Note 3] MJPByron:
Those who have a Note 3: can anyone report back on how MKV files with 10-bit profile/hi10p play back using MXplayer (Using HW+ or whatever codec works best) or whatever video app you prefer to use?

Sample files in both 720p and 1080p resolution are here: koi-sama.net/files/hi10/
[T-Mobile Samsung Galaxy Note 3] wiimonkey9:
This was one of the first things I tried, to see whether or not it could handle my bluray quality anime. Guess what, IT DOES! Both MXplayer and even the stock player handle hi10p mkv bluray flac 1080p videos with ease. Also subtitles work great in both, but are substantially better in mxplayer which does some effects for the subtitles and can do more than one line at a time.
[T-Mobile Samsung Galaxy Note 3] MJPByron:
Samsung should give you some commission because you just sold me on the phone! <3

Thanks and thanks!
[T-Mobile Samsung Galaxy Note 3] RMXO:
Can you try out Dice player to see if that app works also?

https://play.google.com/store/apps/details?id=com.inisoft.mediaplayer.a

Use the provided codec with it please. The codec has to be in the internal sdcard & link it in Dice settings

TYVM
[T-Mobile Samsung Galaxy Note 3] RMXO:
Here's the codec since I'm unable to edit my previous post
[T-Mobile Samsung Galaxy Note 3] wiimonkey9:
It worked both without and with the codec. Subtitles worked better than the stock player, as it showed multiple lines at once during openings with karaoke lyrics, though both lines were on top of each other, instead of one being on the bottom and one being on the top like mxplayer had it. There are possibly settings to play with subtitles and such, but either way it seems that the phone is playing videos like a boss.

For testing I was using these videos: http://www.nyaa.se/?page=view&tid=236223

I'm about to test http://www.nyaa.se/?page=view&tid=446022

and one of the most subtitle intensive videos I know, the first episode of this http://colormesubbed.com/the-world-god-only-knows-ii-bd-vol-1

I'll update this post when I am done testing.

Update:

Alright. The stock video player failed to play both of those, and only played the audio and basic subtitles. MXplayer and Dice player both played the World God only knows video perfectly, but with only MXplayer perfectly applying all of the subtitle effects(which is pretty impressive). They both needed S/W rendering to play it however. They could only play Garden of Words with S/W rendering as well, though it did lag and stutter. The video for Garden of Worlds is honestly a nightmare with even most laptops being unable to play it, though I do expect that the Note 3 will eventually be able to play it with better optimizations from the video player apps in the future. Even though the world god only knows video was the same codec, it was at half the bitrate and had 2-channel sound instead of 6-channel. Like I said, that video is an overboard example. The phone literally plays every other video in my collection.
[T-Mobile Samsung Galaxy Note 3] XellossMetallium:
Thanks for the report, hi10 compatibility is a major point for me too!

So, all videos play fine, even 1080p hi10 subbed, except some pretty heavy ones, like Garden of Words..

Maybe this was due to the bigger size (a movie and not episodes) and the sourround sound?
[T-Mobile Samsung Galaxy Note 3] dragonstalker:
Is this for a particular type of anime. or just Anime in general?

Is this for specific MKV files running bluray (fullHD) rips?
[T-Mobile Samsung Galaxy Note 3] GameBoiye:
This isn't specifically only related to Anime or MKV files, it's more specifically related to the h.264 standard. You can read a brief description of it here: http://wiki.xbmc.org/index.php?title=Hi10P and a more indepth description here: http://x264.nl/x264/10bit_01-ateme_pierre_larbier_422_10-bit.pdf

While it can be used for any videos, it's primarily used for Anime as it can provide better video at the same bittrate. It fixes a lot of problems that come with animation being encoded such as banding. It can be used for regular content but the benefit for non-animation medium is not enough to justify the increase in processing power and lack of hardware support to get people to switch.

[Android Q&A, Help & Troubleshooting] majdinj:
Try to flash stock ROM that has bootloader or ask any body to dump you Sbl.bin from his GS2 device. If I remembered correctly, GS2 has 2 partitions that includes bootloader, one in /dev/block/mmcblk0p2 and extra one in /dev/block/mmcblk0p3 as a backup,, So if you didn't flash wrongly the kernel on the 2 partitions then extract it from the un-overwritten partition (/dev/block/mmcblk0p3) and just flash it over the main partition (/dev/block/mmcblk0p2).

I don't think they will work the 3g and 4g bands are not the same
[T-Mobile Samsung Galaxy Note 3] RMXO:
If its the same as the S4 LTE then all you have to do is use a TMO kernel.

I'm pretty sure the GN3 Int LTE & TMO will be the same since they are Snapdragons compared to the Int non LTE with Enyxo (sp).

Bands have nothing to do with ROMs since you can add your carriers APN yourself.

With that said, we will find out soon enough. Just have to be patient since they device just got released.

This is probably why I'm waiting a few wks to months to buy the GN3.
