kexec recovery questions? - Verizon Samsung Galaxy S III

Ok i am running beans rom and am new so bear with me. i understand kinda what kexec does. I have it working i think? It is however booting into recovery after its been shutdown and when i reboot it seems to loop 2 or three times before starting up?
What i did.
Root
installed CWR 6.0.1 (which i believe supports kexec)
Wiped and flashed Beans Rom
is this right? i see that there are recovery images on the kexec forum. should i use one of these instead? Also where is the custom boot.img ? on the sd card? will a nandroid backup from a stock root take me all the way back?
I really appreciate it

Kexec makes the phone reboot several times. It's just working it's magic. Small price to pay for a custom ROM.

I love having it overclocked to 1.9GhZ .. WOW FAST! what about on a cold boot? do you boot into recovery? i can deal with the reboot but the whole turning the phone on thing sucks

You boot into recovery, hit reboot, and it does the same thing.

Ok so it is normal for it to bootloop on a restart, and on a cold boot to go staright into recovery. So once your in recover from a cold boot just hit restart now and it will boot up.
Where is the custom kernel stored at? uis it booting it from the internel sd card? if so where would it be? What if i want to try a different kernel? All i did was flash bean Rom?
what does it do when you repack a recovery image with the custom kernel. kindof explained here
http://forum.xda-developers.com/showthread.php?t=1773514
Also i was doing some research and heard that it is possible ( or maybe being worked on) if you take some sort of image and put it in the /cache that it will not boot loop? by the way i may be wrong. Just interested?

Just tested with ROM Mananger, it can backup just fine.. as soon i choose a ROM to install it loads recovery and fails, just like when you do it manually.

Sounds like stock recovery installed itself. If you are rooted remove/rename /etc/install-recovery.sh then reflash cwm manually or through rom manager.

I have had this happen on my NS4G. I know they are a little different, but it seems like you are having the same thing happen that I did and to solve it, I open Windows command prompt(or terminal depending on you OS) and fastboot flash recovery (insert recovery.img name here) and reflashed the recovery partition with clockwork. Very easy fix. Just make sure you boot straight into recovery after flashing and flash the Rom you want to flash before booting back into stock(also make a nandroid before that). After that you shouldn't have any more problems unless you unroot. There must be a small glitch somewhere when flashing the clockwork doesn't fully erase stock recovery partition.

Pretty common lately...Android for Nexus S recovers its recovery if it is changes...
"You dawg, we heard you like recovering your recoveries, so we made recovery recover in recovery." and all that...

The Nexus one did the same thing. Most OTAs verify / replace this file. It's easy enough to deal with if you're unlocked and rooted.

It went bad. No idea what happened.

Went to flash an updated Rom on my ATT One X. Been using CWM recovery.
Reboot into recovery, wipe/factory reset.
Go to find the file, SDCard is almost completely gone/items deleted.
I load up TWRP, mount the SDCard, nothing, all gone. So I just format the SDCard, copy the new Rom over to the SDCard root.
Reboot into recovery. Try to install, when I select it in TWRP, swipe, it sits, then just reboots the app and goes back to the main screen.
At a loss right now, phone apparently soft bricked. Maybe bad Rom zip?
Rooted/Unlocked of course, been working fine the past week. Only had the phone 1 week.
Ideas? Help..haha...
Easy, except you gonna have to reunlock boot loader.you can't boot into fast boot OEM relock bootloader and run ruu. You could also try using fast boot to flash something.

Or it might be a case of twrp going bad. Fast boot flash recovery img and boot back into recovery.

It was clockwork I was using at the time.
Everytime I rebooted into recovery and selected the file to install, more stuff was missing.
I'm wondering if the SDCard got corrupt, recovery went crazy and wiped etc...or bad Rom.
Redownloaded Rom.
Reformatted SDCard for good measure since it was all pretty much gone.
Flashed TWRP back as the recovery.
Installing the Rom now. CleanRom 4.1SE.
But...all my Sh&t is gone off the SDCard. Backups, photos etc...buh-bye forever.
Side note, my camera lens area on the phone has been getting hot. Not sure where the processor is located on this phone, maybe it is just doing that while trying to install Rom and CPU is running a little hot and normal?

Cwm has been known to have instability which is why almost everyone suggests using twrp, which is officially supported.

Ok. I noticed it was nowhere near as complete and slick at say 4EXT recovery on my Inspire and suspected some weirdness was going on.
Back on TWRP now and seems to be installing the new Rom I just downloaded again.
Rebooting now...guess I should start copying my SDCard to my computer
Go to cnet.com and download recuva. Do a deep scam and it will recover most of your stuff.. worked for me.. do it on your computer.

Ok, cool, will give it a look.
The CleanRom thread blew up, apparently me and bunch of others had this happen using CWM and the latest build....
All working again, now if I can recovery some stuff, like the photos I had, that would be nice.
Appreciate the replies and help.
Edit: recuva didn't find anything useful. SDCard was blasted for good somehow.

scrosler warned very clearly (even before the latest 4.1 build) not to use CWM. Why so many people chose to ignore him, I have no idea. For some reason the SD card wipe issue was much worse on CleanROM 4.1 than previous versions (and other ROMs).
Take note that the SD wipe issue has also happened on TWRP. Safest approach is to backup SD data to your desktop computer before flashing anything. In particular, your Titanium folder and anything not easily replaceable (photos, etc.). Its a bit of an annoyance to have to do this whenever you want to flash something. But until the cause of the issue is found and fixed, this is the safest way.
Not sure why everyone is blaming the Recovery's for loosing pictures and stuff from there internal SD card. Same thing happened to me with my HTC Touch Diamond, We all came to the conclusion it was from so much flashing. I have used both recovery's and lost pictures and My Documents. Just my 2cents worth.
Is there a tutorial somewhere showing how to switch from CWM to TWRP?

Looking to flash a new kernel.

I rooted my phone with the quick root tool from noxious Nina. I want to flash a new kernel so overclocking is capable. can I just install and run the vzw ez unlock from the play store or do I have to completely flash a new Rom and all on my phone? any help would be appreciated. thanks.
The EZ unlock tool works great!!! Just make sure you flash the correct kernel.... AOSP kernel for AOSP base ROMs and a stock/touchwiz kernel for stock/touchwiz ROMs. Most of the ROMs floating around have a kernel built in specific to that ROM. Happy flashing and make a nandroid before anything!!!!

I have everything backed up with TB. do you know of a good stable stock Rom kernel that can be overclocked.
Synergy is stable and good. I have been running that since the beginning. I am gonna jump to ParanoidAndroid this weekend since most of the bugs have been worked out. You can search around for the most compatible OC apps and methods. I normally leave things be unless I need to change them.
Sent from my SCH-I535 using xda app-developers app
Ok soooooooooooo I have another question. I'm looking at flashing clean kernel. I want to use vzw ez recovery. Has any one done just a kernel with this app and how did you do it. Just select your image and click flash or reboot recovery. I have done research on this but I have yet to find a solid answer on how to do it.
Sent from my SCH-I535 using xda app-developers app
I normally just reboot to CWM and flash away.... I don't use EZ for anything other than choosing recovery and unlocking the bootloader. If you're not on a custom ROM you can use EZ to boot into recovery after flashing the recovery of your choice.
Sent from my SCH-I535 using xda app-developers app
So if I use ez and flash into COM 6.0 then I can go into download mode with vol up home and power then just boot to any Rom that way?
Sent from my SCH-I535 using xda app-developers app
I don't know if it still applies but you aren't supposed to flash kernels with ez recovery.. I did that once and got stuck in a boot loop. That should be used for recoveries only. Use that to flash cwm and go to where you downloaded your kernel..most likely your download folder and flash it. But as stated before make sure your kernel applies to your ROMs tw=tw aosp = aosp no crossing. I personally still use cwm 6 although that was a recovery for kexec methods..it can still be used...for flashing ROMs make sure you know if you have to wipe data and cache as well. You can get into some nasty boot loops and bricks if you don't. I personally do a nandroid and then wipe everhthing then flash a new ROM...just a force of habit. I hope this helps..hit the thanks button if this helps you at all.

Also to add to your question..you flash ROMs from cwm recovery. Download mode is used for Odin to flash stock ROMs and stock rooted ROMs. To boot into cwm from an off state its power volume up and home at the same time. From there back up using the backup option and once that is complete wipe data/wipe cache then go to install zip from SD card or ext SD card wherever you downloaded the new rom and flash that and don't panic if your phone doesn't boot up right away (hanging at the boot animation screen) the first boot always takes the longest.

Powering on

Hey guys i just got this phone from a random on craigslist and hes unlocked the bootloader and stopped there. I dnt know what method he used but in order to power on the device i have to use certain button combos. Example it boots straight to recovery so i reboot now and while its rebooting i have to hold both volume buttons and the power until a white lettered screen pops up and use volume up to power on. And tips? Ty in advance.

on the white-lettered screen try and choose Bootloader. if you can get there you can flash either CWM or TWRP recovery, then flash a working system, or else do a full firmware flash with RSD Lite. or if he already flashed a custom recovery you could boot there and try flashing a working ROM.
Hes got cwm on here. And from what i can tell just rooted the stock rom. Ive never seen a device having a method to power on except maybe a semi tethered jailbroken iphone. Idk

Any suggestions for roms for when i get this figured out?
Sent from my XT897 using xda app-developers app
The device should turn on normally, unless he did something to put it in a bootloop. That's why i figured your basic option was to do a stock restore of some kind.
Check the dev. sections, but rooted stock is basically the only option at present. There are starts on CM9 and CM10 builds, but i don't think they do a whole lot besides boot up. There is a deodexed version of stock that you can flash, and at least apply some tweaks and such
Right on thanx man ill try it and see what happens.

Ok new topic. I think the dude i got the phone from unlocked the bootloader but didnt root it. He said it was rooted. But when i dl rom manager it said i wasnt. So i guess my question is how do i root the thing?
Sent from my XT897 using xda app-developers app
Ah ok, if the bootloader is unlocked, just flash either CWM or TWRP recovery thru Fastboot, then boot into recovery and flash SU.
Edit: after flashing recovery, make sure to boot straight into recovery by holding the volume up button while rebooting. If you boot into the system, it will probably overwrite your flash with stock recovery.
Hes already installed cwm. I cant use regular boot methods. When i reboot the phone it boots into recovery. Thats when i hold down all the buttons to bring up the boot options screen. So basically all i have to do is flash the su file? Btw I tried doing that along with flashing a kernel and cm9 it wouldnt boot into the rom.

I'm not sure how you're sending all these messages from a dead phone...
But regardless, CM9 doesn't really "work" per se. It boots, sure... but nothing else works.
You're going to have to flash one of the stock backups people posted around. I know there was a .win backup of everything - which you'll need TWRP to restore.

Display went blank, sound still there, now stuck in bootanimation

I was running CleanROM Inheritance 3.4.something. I had just rebooted the tablet, battery was around 95%. I launched an app while reboot was still going on, as evidenced by the toasts that came up regarding superuser permissions.
And then it happened. The display went blank. I still had sound. Hardware buttons did nothing until I held the power button down. Device went into reboot and stalled at the bootanimation. More than 5 minutes went by so I rebooted into recovery.
While in recovery, I poked around for a backup to revert to. I have misplaced my recovery SD card...but no big deal. I was considering updating to CleanROM Inheritance 3.4.7. I downloaded that from the interwebs, copied it to an SD, then booted the device into recovery and flashed it. The flashing process had no issues and I rebooted the device.
Now the device is still doing the same thing. Still stuck at the bootanimation. Been another 5 minutes on this one too.
I compel thee to opine.

Sounds like something got corrupted. Might be worth doing a factory reset and reflash the rom to see if it boots?
Factory reset from recovery. Reflashed 3.4.7. Rebooted to clean install. Joy.
Ty sdbags...you rock. Now that I'm at square one again I should go with a 4.2.2 ROM.

Yeah you need to flash twrp with fastboot, download stock firmware from asus unzip it and flash it with twrp then re-flash twrp again with fastboot (the asus firmware zip will wipe twrp) then install CROMi-X

Δεν είμαι σίγουρος αν κατάλαβα καλά όλα αυτά.
Yeah means I need a PC or just do it all from TWRP recovery (I think I have 2.3.1). I was looking at the CROMi-X thread and didn't see any need for a PC if I am already running a custom recovery and ROM. I might just stick with what I have for now...don't want to get in too deep. Been a while since I've done anything with the TF700 anyway, barely even used it last month.
If I can't do it all from flashing from recovery, I need to do more thinking and reading before I do anything else.
Thanks again for your support.

Oh I actually didnt see The bootloader package on the Cromi-x thread, that should work fine. I tried this method long ago, but my bootloader package didn't have a custom recovery included so i still needed to use a pc to fastboot one on. The cromi one should be fine
Yes I prepared the recovery and bootloader as one so as long as you have any custom recovery installed you can use my package to get to the right supported versions. Twrp 2.6 still has issues hence why I haven't upgraded yet.
I have done all the flashing. All is good. I am happy with the update but I need to thin out my apps. I am curious why there isn't an advanced power menu (shutdown, reboot, recovery, hot boot).
