[Q] Skyrocket will boot into recovery and download but hang when booting all ROMS

The Phone was working fine. When it stopped sending emails, i rebooted and it showed the "samsung" boot screen, then the screen turns black and there is nothing. Sometimes, it will boot into ROM after sitting there for 30 minutes. It is SGII skyrocket running CM 10.2 with TWRP. Tried flashing stock rom and various backups and roms. A few days earlier I had flashed a rom to experiment but ended up reverting back using a backup. I am able to get into download and recovery mode. Is it possible I corrupted something and what do I need to do to get it to boot correctly? Thanks.

Flash the proper recovery, then wipe and flash the Rom again. I'm not going to help you past that, since I've already explained this exact problem last week.

I was given the advice to use odin and flash a stock recovery. Havent tried it yet, but its on my list. That and finishing the christmas tree. My problem was similar and phone would randomly kernal lock during boot.

Thats not helpful. What is "the proper recover?" TWRP has been working for months. Not even a link to where you explained the solution? I searched the forum before I posted and I didnt see it. I flashed the stock with odin before posting and it did the same thing.

Search 'black screen boot' in this forum and you will find dozens of threads describing the exact same problem. Read some of them.

zjsdlr2,
read ALL of this thread first http://forum.xda-developers.com/showthread.php?t=1773659
You have many options for ROMs so YOU need to decide what you want to use.

[Q] Buying the phone today and rooting?

If I buy the S3 from a verizon store today brand new, will I be able to root it and unlock the boot loader still or will it come with a firmware too new?
Sorry if this was answered before. Tried searching but couldn't find results. If they are out there then I blame iOS 7 and my iPhone that needs replacing

I'm not sure what, if any, updates they've had in the last few months but I just got my s3 in August. I did take an update on it and had no issues with using casual to root & unlock. Perhaps someone may have a more recent experience.

That's great to know. I take it I can use custom recovery, and replace the ROM entirely? I don't want to deal with an OTA removing root on me.
Thanks

You should have absolutely ZERO issues with rooting/using a custom recovery, etc... Casual couldn't be any easier.

Not necessarily. If he gets a phone that was manufactured after ~July 2013, he'll have problems. There was apparently a silent change to the firmware/hardware/boot process that prevents any of the currently-available custom recovery packages from working. (Not clear on what the change was other than they apparently back-ported it from the GS4 and it requires a change to the recovery's kernel before anything will mount.) I've been fighting to get my brand new GS3 rooted and a custom ROM on it for almost two weeks now.
Trying to do so with Casual caused an endless boot-into-recovery loop because the recovery couldn't clear the cache and reset the 'boot into recovery' flag that ADB set; I was forced to flash back to stock recovery to fix that.
I did manage to get both TWRP and CWM loaded via ODIN, but every version I tried (dozens in all) refused to mount any partitions - it couldn't mount/read from /system or /data or /sdcard or /cache, so there's no way to flash anything. The closest I've come is by using the hacked-up versions of TWRP and CWM from this thread, but they're built for to Sprint phones, so now when booted into Recovery my phone thinks it's a Sprint and won't flash the VZW versions of anything.
So far, every person who's having this problem appears to have gotten their phone in the second half of this year, so I strongly suspect that buying one now will have the same result.

Not necessarily true on that... I got mine last month... I did have issues with using the latest casual Root method, but the all-in-one casual Root works perfectly! But I would suggest downloading rom manager and letting that app install recovery for you (TWRP and cwm touch both caused issues for me). If you need a step by step, pm me and I'll write it up for you...

I have no problem getting the recovery installed. The custom recoveries are just *non-functional* because they can't mount any partitions. The error logs' are pretty clear, and every custom recovery I've tried behaves exactly the same.

[Q] random shutdown and bootloop

Hello First post here so hopefully in the right place! I've got a nexus 5, UK model purchased around January time. I had rooted, running stock with SuperSU installed and a few apps installed with xposed mod.
It was running perfectly fine, until a few days back where I was required to reboot, it then got stuck at the Google screen and wouldn't go past that, I turned the phone off for a while and eventually could get into it.. Great, until it happened again.. I spoke to a friend who said perhaps it was the xposed which was causing it, so I flashed back to factory, ran it for a while and it was fine, so went back to root and tested it, was stable so I reinstalled xposed.. It then got stuck in the bootloop again, so flashed to factory certain that it was xposed causing issues. I'm now running factory, however the phone will still get stuck in bootloop but will also randomly reboot itself now.. Has anyone experienced this? After scanning the forums I can't find anything so hopefully someone can help!! My boot loader is still unlocked.
Thank you, Jordan.

Are you able to flash a custom recovery? like TWRP, PHILZ, CWM? try it.
if successful, flash a custom Rom. just to discard the possibility of emmc failure.

[Q] Help, I deleted my stock rom by accident

This is my first post and I'm not sure where to put it but I hope this is right.
I'm kinda new to flashing ROMs and was trying to flash one using safestrap on my GS3. I couldn't find one that worked and went back to my stock ROM. In the stock ROM cell service completely died and wouldn't work, to combat this problem I removed all ROMs, ROM slots, and wiped the stock ROM cache. Nothing. So then I restored to my nandroid backup I made yesterday and that deleted my OS. Now when I boot it just gets stuck at the second Samsung boot logo (there the first one that just says "Samsung" and "unlocked", then the second on says "Galaxy SIII" or something) now I have no OS and I'm not sure how to fix this, can I get some help please?
Okay, I got the stock firmware installed but I still have no service anywhere. Any ideas?

First thing I would do is make sure your imei is still present in the about phone section. If it is, move on to the next step.
I would go completely back to stock, Odin flash either the stock 4.3 or 4.4 image depending on which you were on. If you're unsure, post what it says in download mode.
If you do that and you still have no service, then go to verizon and get a new sim card. Flashing a new modem wouldn't fix this situation.

[Q] Flashing no longer possible: Flash successful but system does not change

Hello!
I can no longer flash anything to my GT-P5110, even factory reset has no effect. The internal storage seems to be read-only.
I think this is a longer story: About one year ago the stock firmware became incredibly slow, to the point that processes started to force close, then my user data was lost, and after factory reset the tablet went into endless boot loop.
So I decided to give CM10 a try and it worked flawlessly. The tablet was fast again. I even could upgrade to CM11 later. But around 2 month ago, only sometimes processes started to force-close or the tablet randomly rebooted itself - mostly during charging. I left it that way in the charger for some days because I had no time to bother with that issue. Then, I tried to factory reset my device only to find out that this has absolutely no effect. Installing app updates: No effect. Changing system settings: No effect. And apps start to force-close at an insane rate short after boot. The device is unusable. My could only shut down and reboot into recovery. I left the tablet lying around, turned off, out of charger, for 2 months. Now I tried to investigate:
When I "adb shell" into recovery and call dmesg, I see lots of these lines:
Code:
mmcblk0: timed out sending SET_BLOCK_COUNT command, card status 0x400d00
I think something is really broken with the internal storage. I tried to flash a newer recovery but it has no effect, even when done from download mode.
Factory reset sometimes fails with an error. Reinstalling CM fails with an error. Wiping cache seemingly succeeds but I'm sure it has no effect. I tried installing SlimRom instead which seemingly succeeds, too - but after reboot I'm greeted with the CM boot logo again.
I tried to flash stock firmware with Odin. It is very very slow, runs for about 15 minutes, then fails at around 50%. Of course: That "half flashed firmware" does in no way affect the device: It still boots CM11 "without problems", then a few seconds after finishing boot (showing home screen), force-closes start to pop-up.
What should I do? I suppose the device is out of warranty for a few weeks or months, now. And even when not: It has been flashed with CM, the triangle counter is not zero. I suppose that combination of problems (read-only/failing storage, non-stock firmware) voids warranty in a way that Samsung will deny any repair. If at least I could return the device to stock firmware things would be different maybe.
Any ideas what I could try? Is it possible that the internal storage is simply fried? fsck'ing the partitions shows no errors, just the data partition is unclean with unwritten journal data but all data is readable. So the internal storage has probably not died. It just sticks to read-only mode for whatever reason.
I've found some posts with similar problems but those seem to be about older Galaxy Tab 1 devices built 2011 or before.

Just reading over this and it sounds very similar to what I'm currently facing, which is doubly annoying as no one else has chipped in a solution
I had reboot issues with my Tab2 10.1 (GT-P5110) on stock so after realizing I'd need to factory reset bite the bullet and rooted so I could use CM10.
Had occasional reboots but nothing I couldn't live with however from yesterday evening the tablet is seemingly stuck in a boot loop. It comes on, some apps fire up and an update starts. Sometimes apps force close then BOOM I get the boot splash screen.
I've tried factory reset in recovery (CWM 6.0.2.7) to no avail and wiping just about everything which also had no noticeable effect as all my settings and the rom are still the same when I get back in (albeit briefly!).
I've tried flashing new recovery via ODIN which reported a success however that also didn't appear to take. I'm beginning to think it some serious file system or storage corruption ;(

Same problem here...
Hopefully someone can come up with a solution or at least a cause. I've tried to Odin every recovery available for my 5113 and nothing has taken. I'm currently on Omni with cwm and tried to update to the latest cwm and twrp and aroma installer yet nothing takes. I too rooted because of the incessant bootloops about 3 months ago.

For what I can tell, my device is effectively read-only. Even in download mode (Odin) I cannot even flash a different recovery (tried to flash TWRP, still boots CWM).

exactly, can't even uninstall an app. It's as if it boots from a permanent back up because even deleting pictures or files isn't permanently successful. You can uninstall and delete to your hearts content, get false hope, and get crushed after it reboots and everything is unchanged

Not looking very optimistic for this I was getting a similar inkling that it's gone into a permanent RO mode as not even the wipes from recovery have an effect. I'd also tried un-installing apps as I noticed one updating and thought it was crashing it however even when it did fire up and I disabled WLAN to stop Play Store auto-updating and removed the app on the next reboot cycle the app was back:crying::crying:
I fear I may have a big white paperweight....

Sounds like the internal partitions might need to be completely reformatted. This CAN be done through recovery, but is tricky... However without actually having your device in my hand I'm not sure 100 what the best course of action would be. Try searching for the commands to format (or maybe someone else will post them) or maybe PM me for them but no promises. I won't post them publicly on XDA because honestly there are too many users who do stuff like one-click root and don't actually know what they're doing and I don't want to be in some way responsible for someone following the command wrong and bricking their device for good. I don't need that on my conscience. Personal choice.

Would this method be any different to the way it attempts to reformat the internal partitions when you select to format the various mounts from CWM? If so I'm more then willing to give it a go as I really have nothing to lose as the damn thing is useless atm!
