Did Lag Fix for Galaxy S and now my phone won't boot

Just done the lag fix for my Galaxy S and it all seemed to go through fine. Tried running Quandrant benchmark to test it but it crashed. I turned the phone off and on, got the Galaxy S i9000 screen then is just goes blank, literally nothing, not even the menu or back lights. Had to then take the battery out to reboot but got the same blank screen.
I can boot into recovery but rebooting from that doesn't work either, does anyone know how to fix this? don't want to try anything for fear of making it worse

Try getting into the Recovery Mode with the 3 button combo

What lag fix are you using and what firmware are you on?

wont boot..
Hi, strangely but after the 2.2 upgrade on my SGS (it was JF5 and I made the trick with the registry to JPC and upgrade via KIES) it happened to me as well.. just a beautiful "S" blinking on the screen and nothing happens. On the time of upgrade in the instructions it was written that with the 3combo trick to make factory reset.. then everything worked just fine until yesterday...
Without installing any new apps, just browsing and trying to make my AllShare working.. I decided to gave up and without reason I have decided to restart my phone just to free RAM and etc.. And by no reason at all I got the same ****ty "S" screen and no boot.. tried first to wipe the cache.. didn't help.. and just after again factory reset it worked out and the phone is okay...
So probably for you the solution is really only factory reset, however this is very strange behavior

When I first applied the lagfix from the market in apk type it required an auto reboot to see if things wokred ok (as prompted on the screen).
Anyway, my phone stuck to a black screen and I was in a very inconvenient situation not to be able to use a PC (yeah, now I know I shouldn't mess with stuff like that while I'm on-the-go).
Long story short, after a couple of manual reboots (by taking out the battery for some seconds) it came back to life and no problems ever since. So before flashing (which can be rather incovenient if you have no backups etc) try the above mentioned method.
Original JF3 firmware (yeah need to change that).

[Q] Problem: Unresponsive screen after update

My wonderful wife gave me an Acer a500 for Christmas. Awesome gift. I had rooted it immediately with no problems, since all of my phones and families phone are rooted, it just seemed to be the natural thing to do.
As someone that "plays" with their android a lot I did all of the backups. Well, the time came to have my tablet "approved" for use at my company and also have the appropriate "encryption" software and keys added. Just as a precaution I decided to restore the original backup and unroot the tab.
All was going well until I received the update message. I went ahead and downloaded the update and ran it. During the install process it froze. I thought it was just busy so I left it for a good 20 minutes and finally realized it was frozen. I rebooted and it went through a couple of reboots and finally settled on the lock screen. But now I find the touch screen unresponsive.
I plugged in a mouse and keyboard in hopes that I could get back into it and start over, but, although, the mouse shows up, it is jumpy sluggish and will not grab the lock to slide open and eventually freezes.
I have tried all of the "update.zip" files I could find and they all fail at one point or another.
ADB allows me to explore in shell but since I unrooted, I cannot get su privileges.
Acer is of course, useless and the vendor it was purchased from is worthless.
I have been through every thread I could find and tried every trick I could come up with. Now I'm just stuck.
Any help is appreciated

I've had this a couple of times already. Usually just turning the screen off and on a couple of times does the job (the issue seems to be with the driver, also on various custom roms). Just try it after each off-on cycle, most of the time it takes no more than two or three tries, though there are exceptions.

Thanks, but it has been rebooted many many times since it's demise.
Decided to skip sleep tonight and keep plugging away.
I found an update.zip recovery file for an a501. Figured I can't do much worse so I went ahead and ran it.
It froze at about 95% but.........
Good News:
The tablet is responsive and touch panel works again.
Bad News:
It boots straight into system settings and although you can open the settings menu, nothing actually launches.
Decided to try all of the old update.zips and still everything fails.
No more ADB response.

When you originally unrooted your device did you revert back to the stock recovery or did you leave cwm on your device?? If you left cwm on your device that may be the problem with the update.zips and OTAs.

You are sooo right. I've never gone back to a stock rom before and I completely forgot about reverting to the stock recovery.
As a matter of fact, I was on Civato's Flexstriker 3.2.1 rom with the new CWM before I reverted back to the stock rom.
Well, at least we've determined my stupid mistake, but now the question lies: "How do I get back to any working rom?"

Here's an update. I did find an update.zip file that also begins to load but does not finish. It stops at 95% still.
I will attach the photos in case someone notices something otherwise I am at a loss. In addition to all of the above, I tried everything I could to get into APX mode but nothing. I am willing to try almost anything at this point, so all suggestions are appreciated.
Something I noticed was the recovery for the a501 was android with gears spinning in the body. The recovery I have now is a package with an arrow. The recoveries are different. The current update file is Acer_A500_1.145.05_COM_GEN1
So this brings me to a question: Can I put Thor's 1.6 CWM back on the a500 and at least work from there? I do have my original backups and thought I might be able to get somewhere that way.

[solved] Possibly bricked only the recovery partiton?!

okay so after trying some other options i was able to solve this problem, here is the how to in case this has happened to anyone else. my original post is below the how to.
1.flash the sbf that returns your defy to stock eclair using a different T-Mobile sim, after it is done flashing you will seem to still have the problem, except it will say no sim emergency calls only.
2.power off the device and install your original sim from T-mobile.
3.reboot the device and you will not be prompted to setup motoblur, because you device is in soft brick limbo still, but you will have laggy touch responses, be patient with your device as you navigate to settings>privacy>factory reset and confirm. ( this process will take much longer than usual and the progress bar will not show any progress but it will shutdown and reboot as it normally would with a factory reset)
4. you will now be prompted to setup your motoblur account ( if you are not restart the steps until this happens, if it does not happen your device did not actually do a factory reset you will need to try again until it does ask you to setup blur, this is your sign from the moto gods that your device is no longer in softbrick limbo)
5. setup your blur account ( you will still have no recovery menu at this time so don't try and check or you will have to start back over at step one)
6. now navigate to settings>about phone> check for updates
7.download and install the update to froyo ( durring downloading you phone may shut off several times, however if you reboot it will automatically pick up the update where it left off as if your device never powered off to begin with)
8. once you have installed the update you device will be back to froyo stock and your recovery partition will no longer be bricked
9. enjoy your defy once again, and be more careful with your device in future ROOT mods and tweaks, cheers!
10. If this helped you recover your device please thank me for this solution.
okay so i am new to posting on XDA and i will try to organize my problem as best as possible, but i may need much guidance on if i am posting in the proper forum.
here are my details of my device and the problems i am facing with my device currently.
Motorola Defy
MB525
T-mobile US
stock Froyo rom 2.2.1 ROOTED overclocked with milestone overclock to 1224 mhz @ 85% voltage /V6 SUPERCHARGER SCRIPTS. MODDED BUILD.PROP TO REFLECT THE MAX HSUPA CATEGORY 34/MAX HSDPA CATEGORY 36/ GPRS CLASS 10/ HSXPA=2/RO.RIL.VIDEO_MODES=TRUE EVERYTHING ELSE IN BUILD.PROP WAS STOCK EXCEPT WHAT THE V6 SUPERCHARGER SCRIPTS CHANGES. I was running a custom bootscreen that i placed in the location of the old one using ES file explorer with root browsing rights, i had defy Recovery installed but only used it basically as a system restore app ( context of previous statement is relating to system restore if you were talking about a windows machine) used Avast anti virus as root installation w/antitheft installed used system tuner to manage startups down to core services or other services i did want to run at boot i.e. stuff like facebook and weather channel.
DEVICE WAS ALSO SUBSIDY UNLOCKED
SBF started with and reflashed to try to correct problems was JORDN_U3_6.36.0_SIGNED_USAJRDNTMOB1B4B5DE1028.OR_JORDANTMO_PO22_HWp3_SERVICE1FF.sbf
****NOW TO THE PROBLEMS****
I was starting to think that maybe the v6 supercharger scripts were not really doing anything performance wise for me as it would disable my overclock settings at boot and i would have to manually invoke them after everything had requested its SU rights at boot. so i decided to get rid of the v6 supercharger scripts and all other softwares pertaining to managing and running the scripts, I decided the best way to do this was to do as i had always done in the past when wanting to re-tweak my phone and use the stock recovery to start fresh with 0 tweaks and only apply the ones i wanted after restoring to stock, when i used the stock recovery this time it didn't work, i booted the phone back up after wiping data/ factory data reset and to my surprise the recovery did nothing but delete the SU.apk the custom boot was still in tact, everything else listed above still in tact except for the phone was obviously throwing errors left and right because there was no SU for apps to request permissions from, so i reinstalled the SU.apk just to make sure i didn't have to deal with the device being slow while restarting the process of doing a full wipe. this time i used the DefySDrecovery.apk i mentioned above to do the same steps and while adding wiping the dalvik cache after wiping data and before invoking the recovery, it then gave me the same error i have always gotten when wiping the cache which is
e:\ cant mount cache partition
e:\ cant find /recovery/caller
e:\ cant find/recovery/cache
(this has never caused problems with the device once recovery was finished)
this time however I was only able to boot(loop) to the moto logo
so i reflashed The above mentioned SBF and the device booted normally i went through the entire setup like it was a new device with blur and google and it finished. when I got to the home screen it was frozen and would not respond to touch it also showed to have no cellular signal, i turned it of and back on and it made me go through blur and gmail setup again, went to home screen same thing frozen with no signal.
i reflashed the SBF again thinking maybe something went wrong as they do sometimes with RSD yet still finished and passed on everything
the above description repeated except for this time it responded to touch for the first few seconds before it froze completely ( oops! sorry one detail to add when i say it froze i mean froze like would respond to nothing, touch, hardware buttons, nothing) i had to pull the battery in both instances to try and start over, after many attempts of getting in the phone and trying to turn on usb debugging before it froze i finally was able to complete the finger olympics and get usb debugging turned on, i was able to root it using superoneclick so that i could have a look at the logcat in ADB. now in my experiences with ADB normally when you run a logcat command it will print to the screen for about two to three hundred lines and then slow down and only print one to six lines at a time as the server is calling actions when i ran a logcat on this device it runs two to three hundred lines slows down and then runs lines until you close the ADB window i let it run a logcat overnight and it was still running lines the next morning with no sign of stopping where you could freeze the window and read over all the crap it was calling to action, looking at the device durring this process i saw force close windows a few times saying the com.android.process has stopped but the home screen never crashed and the phone didn't do a random reboot. so to sum it all up ( so sorry for the lengthy explaination but i wanted you to have the whole problem fully explained in hopes you wouldn't have to ask for more detail)
it freezes and has no service with my T-mobile sim in it ( if i put my at&t sim in it has service but still freezes)
flashing a new SBF doesn't fix the problem as it should
and there is no way to enter the Recovery Menu now its gone, non existant, cant find it, cant fix it, i'm F***** right now Please help if you know how, and if i totally screwed the phone i'm cool with you saying so but it can still be in a respectful way i already feel like an idiot for not being able to correct this with all the knowledge i have of this phone, a negative attitude insinuated is not going to help me in either direction, thanks in advance for any help you may be able to provide.

[SOLVED] Suddenly G2 boots only into recovery mode (loop)

Sometime last night, my AT&T G2 (D800) decided to go from being powered on and idling, to going into TWRP recovery mode. All by itself. I saw this, unplugged it from USB, and tried to reboot into system mode. But it simply won't do anything except boot into recovery. Powering off, trying to get to the bootloader, none of that works.
This is not a custom ROM, it's 4.2.2 stock from LG. I only rooted the phone, which was several weeks ago, and haven't had any problems, aside from TWRP not wanting to back up anything. I've been using Android since the original TMO G1 with JesusFreke's ROM, so I have a pretty good idea of what I'm doing, hopefully.
The only recent changes I've made are:
I updated busybox about 3 days ago (but have rebooted fine since)
I grabbed several legit apps from the market last night
Last night I also DL'ed, but did not apply, a ~50MB OTA update that has been pending. I don't think that would install without explicit permission anyway, which I didn't give it?
This phone was encrypted from the start. Maybe that;'s what prevents TWRP backups,, but right now I'm seeing TWRP errors/logs saying something like "Unable to mount \data". And yet I can browse to other folders, and see filenames in \etc for example. However, I don't see any files at all in \boot.
Since this phone has no external memory, and it's customized and has numerous configured apps, I really really don't want to have to wipe it. Although at this point, that may not even fix the problem? Even if it did, since I haven't been able to make backup images, it would be a Bad Thing™ either way. (Yes, I do have a secondary plan with Titanium, with backups going to cloud storage, but these are tedious and now a few weeks old. And wouldn't restore the ROM & system en masse.)
Please help.

Solved?
I'm not sure what caused this to occur, but I found somewhat of a solution after digging deep into my Google-fu.
I followed the instructions in this XDA thread and it actually worked. I didn't have adb access, but I was able to use dd successfully. It allowed me to boot into the device, unencrypt it, then arrive at the lock screen.
However, when I put in the lock code, it went apesh!t and played multiple notification sounds, with a blue circular wait symbol. It also flashed the LED from green to blue, as it normally only does during boot. Once I pressed the power button, I was back back into TWRP.
So then I followed Step 2 again, and once in the phone, I used terminal to run the dd command from inside the OS. This might be what it ultimately needs, because the prior attempt in TWRP had an error to the effect of "no space left on device".
I can't call it Solved yet, but it looks good to at least be able to get in and use the phone. I'm backing up with Titanium before I do anything else and will reboot and test its permanency later.

I'm gonna close this thread now that I think I have a handle on what is going on. The fix does survive a reboot, so I believe it's possible to repair the issue permanently per the instructions above. I also ran the phone for 3 hours with heavy app usage and no problems.
I believe what may have happened is my OTA decided to override my choice to NOT update the ROM, as some have reported in this Reddit thread. There's a lot of good info in that one, including how to stop getting nagged by turning the OTA notifications off, or to freeze it entirely with Titanium Backup if rooted.
Anyway, what apparently happens is that when the OTA/upgrade goes to reboot, and encounters a custom recovery, it gets confused... when you try to power cycle or reboot again, it sees the stock recovery still hasn't run whatever it wanted, so it starts recovery again Lather, rinse, repeat.
Fun times.

[Q] Reboots after Lollipop

Verizon Note 3 here, I received the Lollipop ota today and thought no harm in taking it as I was already stuck without root on 4.4.4.
It worked ok for the first couple minutes, then a reboot, then same thing, about 5 minutes and a reboot. Sometimes ~2 minutes, seems using it in any situation made the reboots happen. I did a factory reset thinking that would clear things up. Unfortunately now it is even worse, as it's rebooting anywhere from the first touch to the screen, to about 15 seconds of activity, literally dozens of reboots.
I downloaded the update on my pc and installed via Odin hoping that the ota was just corrupted or some bad luck like that. Nothing changed at all.
It will idle after booting just fine, I just can't do much of anything, every touch of the screen feels like a roll of the dice. Every few reboots or so I can make it to settings maybe but haven't been able to actually change much of anything, not that it would seem to matter here.
I've flashed via Odin twice, cleared the cashe many times, factory reset 3 or 4 times. Am I screwed here? What else to try?
*UPDATE* I flashed back to 4.4.4 with Odin and no more issues. It appears that my device alone is completely incompatible with the new firmware.

I should also note that I tried airplane mode, safe mode, and removing the sd card with no improvements.

After hours of messing with this thing and nearly giving up, not half an hour after I post here for help, I seem to have found a solution, although hopefully not a permanent one. The problem was happening when I would touch the screen, not scrolling ever, but making selections. On a whim I turned off sound and bam, no crashes.
I would still love it if someone had some insight about this problem, or better yet a solution.
I'm not sure yet if it is just the keypress sound that is killing it, or all sounds. I never did have any issues with the stock keyboard clicks now that I think of it, only the menu press sound. In any case it's not every time it made the sound, just half the time or so. Anything anybody could add to this would be appreciated.
*Edit* Not a solution, but it did help.

Well it's not as stable as I'd hoped. More like before the first factory reset now, but still not good at all. The various sounds definitely trigger crashes quickly(menu options, volume pings, mp3 songs from sd card), but regular silenced menu presses do sometimes as well still. Phone also bootloops several times often before it can get booted stable and 100% always crashes immediately if I try to unlock the screen in the first 5-10 seconds after booting up. Not sure if I'll be able to call or text as it's too late to test that atm. I'll update tomorrow, any insight appreciated.

I would say a bad download but I don't remember if ODIN checks MD5 sums (pretty sure it does). I would do a full wipe and reflash the stock image with odin

I am 100% stock not rooted never been rooted 5.0 vzw and I have had a couple of reboots. Never ever had one on this phone before. My old note 3 was rooted but I got this replacement after the root exploits had all been closed.

ehh not all have been closed

What is the root exploit for Verizon Note 3 with 5.0?

None at the current time but CVE-2014-8609 seems like it could be some use

I spoke too soon when I said the phone was usable now. At best 5 minutes of light use as anything seems to crash it now. I did get a fresh image and used it with Odin with exactly the same result which makes me think its my phones hardware or something. Just seems crazy that it was working just fine before the update. The reason I pushed to 4.4.4 and lost root is because my phone suddenly started an issue where it would crash when making or receiving calls. It wasn't caused by any new apps or anything, just out of nowhere. I tried everything then updated as a last resort, carelessly I went to 4.4.4 instead of staying at 4.4.2 and lost chance of root, but it solved the problem I was having. I wonder if the issue is related somehow.

I was able to odin back to 4.4.4 and it's working fine so far, I assumed that you would not be able to revert back like the last ota and just tried it as a nothing to lose last effort. This is very important news to anybody that is having major issues with 5.0. Maybe, just maybe I'll try it again if they make an update patch for reported issues.
But for now, 4.4.4 it is for me.

VZW Note 3 update to Lollipop
I just finished the Lollipop update and my phone is working great for the past 30 minutes. Seems a little slower then usual but have had no issues besides my phone locking up after downloading the update, may have been due to my phone running down to 14%, but after removing the battery for 20 secs and putting it back on, phone came back on, I plugged into charger and started the update. Will post later if I have any issues.

I have been trying unsuccessfully through odin to downgrade but it keeps failing in odin, I downloaded the official firmware from sammobile.

Just curious if u r tried reinstalling newer odin? Try different USB port and cable. At this point maybe even try different pc if u have access to 1
