Can't Load Custom Kernels on Samsung S3 - Verizon Samsung Galaxy S III

So I can't seem to be able to load certain kernels or ROMs without either having my phone freeze up entirely (I tried loading LiquidSmooth v2.37 and my phone kept displaying the Samsung symbol for about half a second, shutting off and then repeating this process over and over) or it gets through bootloader animation (on Eclipse v5.1, CM10.2, or Dirty Unicorns 4.3.1) only to show a COMPLETELY distorted and nonfunctional screen-it shows like 3 battery icons, has a huge message saying widgets loading (even though I have no widgets) or clocks and calenders, and is comprised of colors that don't match the theme of whatever ROM I currently have installed.
The steps that I took to get there were:
1. Boot the phone in CWM (version 6.0.4.3)
2. Wipe data/factory reset
3. Wipe cache partition
4. Flash ROM (zip file) from external SD card
5. Flash Gapps (zip file) from external SD card
6. Flash Kernel (zip file) from external SD card
7. Reboot phone
All of the files I have flashed have been the most current ROMs/Kernels/Gapps and I've made sure they're compatible with my phone, so I'm not sure exactly what's going on. I'm thinking it might possibly be a hardware problem since it happens with the custom kernels I've tried (I've tried it with BMS 3.4.y and dkp 4.3).
Also weirdly for some reason my root isn't lost but every time I try to reboot my phone from CWM, it tells me that that my root access might possibly be lost and it asks me if it should fix it. I haven't lost my root, but this message pops up every time I try to reboot in CWM. I've also tried fixing permissions in ROM Manager (both to make the message go away and to see if that would allow me to successfully flash a custom kernel-it didn't).
Right now I'm running Eclipse v5.1 with 3.4.56-cyanongenmod kernel (it's the one that came with it), but if anyone can help me figure out what's going on I'd greatly appreciate it. The battery life on my phone sucks-I'm only getting 4 or 5 hours with the GPS and bluetooth turned off, so I'd really like to be able to install some other better custom kernels and ROMs. Thanks in advance!

[Q] Simply Honey Revolution 5.1 on SGS

I've got some questions regarding the install documentation of Simply Honey 5.1 Revolution for SGS ROM
Install Instructions Coming From Froyo OR ECLAIR(CM7/MIUI ODIN TO STOCK FIRST)
First Question regarding CM7 - Does this include CM7.1 as well? The example outside the parenthesis says Froyo or Eclair - CM7 is GB so this is not clear
- 1. Disable any Lagfix.
- 2.Download - xxx LINK REMOVED xxx This is the light version with hardly any apps and only one keyboard and 4 lock screens.
- 3. Flash via ODIN. USE 512PIT FILE.
- 4. Let phone boot. Wait 15 minutes and reboot.
- 5. Enjoy. You may now proceed to the MediumOR Large.
What is the difference between medium and large? Where are these files? I see a Light and Full but nothing else.
[/SIZE]
Install Instructions
Coming from Any Gingerbread Rom (If bootloaders aren't installed or you have trouble follow steps above.)
CM7 issue listed above. Any GB rom sounds like any - including CM7 this adds to the confusion of what will/won't work here.
1. You must first be running a Gingerbread rom (Doesn't matter Lindroid, Rainbows, your cousins top secret GB rom.) If you are not then please follow instructions above.
2. Place SimplyHoney5Beta1.zip on your SD card
Filename is out of date. Please link new file or list correct filename. If the ROM is out of Beta, the filename in the instructsions should reflect this.
3. Use rom manager or flash through recovery.
4. Let phone boot. Wait 15 minutes and reboot.
5. Enjoy
The new script is wipe for who come from SH <3.3 and from Froyo/GB!
It doesn't do wipe if you're running SH 3.5+ ROMs! Very Simple and automatic!
I've called it the "Anti-Noob" Script!
ONLY FOR CWM VERSIONS!! ODIN VERSIONS ALWAYS DO WIPE!!
Downloads CWM Full Roms
Simply Honey 5.1 Final
Light: xxx LINK REMOVED xxx 5 Locks Screens/ Modify Power Control Menu Options
Full: xxx LINK REMOVED xxx 10 Lock Screens
What is the purpose of Update1? Should this be flashed after Full? Is it flashed through CWM recovery? Some additional information here might be helpful. It is linked but no indication of why or when one would use it.
- Update1 - Gallery3D, Polaris Office, SNS Account -
xxx LINK REMOVED xxx
Is this section below a second set of instructions - you seem to list a If you have problems section above; however this one is more comprehensive. I'm not sure which one to follow if I have problems.
HOW TO
The anti-noob install script is a double edge sword so to speak. On one hand it is convinient as it doesn't do a wipe install if already on Simply Honey 3.5 and up. On the other some data needs to occasionally be wiped. That said if you experience ANY problem please follow the steps below.
1. Force Close of certain apps...go to settings/applications/manage applications/all and clear data of the offending app.
If that doesn't work then use Tiatnium backup to wipe data and uninstall the app (as long as it's not a system app such as phone or contacts or settings, you get the picture. Now you are free to re-install the app.)
2. The next step is to try and re-install the rom. Boot into recovery and select install from SD. After it's done and you reboot give it the 15 minutes. Now try again to recreate the original problem.
3. If the problem persists then boot recovery and wipe data factory reset and re-install the rom.
4. Problem still there then ODIN to stock (Stock ROM recommendation?)with repartition, ODIN the Simply3.8 Odin/Heim package. After rebooting boot into recovery and install the latest release of Simply Honey.
If these instructions are still useful, please link to SH 3.8 Odin/Heim package pls.
5. If all else has failed make a backup of everything you want saved to your computer. Boot recovery and go to mounts and storage and select format SD. After it's done reinstall Simply Honey's latest release.
6. If your problem still remains after doing all of this or just the last step then I suggest finding another rom as this one may not be for you.
I made an attempt to convert from CM7.1 this weekend; it wasn't clear what was going wrong but I couldn't get SH 5.1 to load properly. I tried to Odin the SimplyHoney 5.1 light version as per the first group of instructions, however, it was unclear whether I needed to repartition or not. the phone began the robot voice indicating partitions were not correct. I odin'd back to stock and reflashed CM7 with no problems.
Please understand I'm not trying to be critical, and I have rooted/flashed a number of phones over the years. Although I've been a fan of CM in the past, it's absolutely not where it needs to be on the Galaxy S/Vibrant and the Nightlies are not getting there fast enough. After reading the settings/features and positive comments for this ROM I'd really like to try it out, but the vague instructions and lack of links are not making this process easier.
If one of the developers can answer some of these questions, I'd be willing to assist writing documentation for this and future SH releases.

Once in the recovery choose "wipe data/factory reset" and validate (pressing camera button).
Also "wipe cache partition"
And then in "Advanced" choose "Wipe Dalvik Cache"
VI) Installing the ROM !
Go back to home menu of the recovery, choose "install zip from sd card" then "choose zip from sdcard". Find the file Smartoonay-1.0.zip (you just copied it on your sdcard) and validate to launch the installation.
Once done just reboot the phone and you're good to go !
You have just convinced me to buy this phone. I was torn between this and the Note, it's refreshing to see some Development on this.
Thankyou very much, your instructions are excellent BTW!
FYI, for me it worked once (after reset) and then went into a bootloop after installing this rom. Never got into fixing it as Vache did not respond anymore... you haven't had that issue?
Regards,
Nika.
Hi,
It bootloops on the bootanimation ? It can happen and usually it works if you remove the battery for 5min.
Can you describe where it stopped working and what you did just before it bootlooped ?
I haven't tried removing the batt, it just bootlooped after my first softreset in the morning. I did try several times, tried resetting all caches, and then reverted back to 1.000.19 eventually and gave up...
I may try again soon... too much work right now
Regards,
Nika.
Going to give it a go this evening.
Really excited to try it out.
So how did it go ?
In my case it keeps displaying the Acer / Android logo... it does not boot (just Android logo)...
Thank´s for me works well
Well...I have tried like 10 times, still nothing.
I started by installing cwm & making a backup (good step to add to your steps in the OP). Then I started install of smartoonay:
1. install 1.000.19
2. boot 1.000.19 once (& configure next, next, finish)
3. install new cwm
4. factory defaults from cwm
5. clear cache from cwm
6. clear dalvic cache from cwm
7. install smartoonay from cwm
Boot wail stop at the acer/android screen (with the 3 green androids).
I have tried fact/def from vol+/- and from cwm. I have tried clearing caches before and after smartoonay. I've downloaded smartoonay rom from vache several 3 times to make sure it's not a faulty rom... nothing...
Restored the backup: everything fine again...but still no smartoonay
Regards,
Nika.
Sorry to read that it doesn't work for you. Have you tried with the .24 official update? It did work for several people.
If it still doesn't work you might have to wait for a next release from vache that will take the smart to a new level ;-)

Nope... for whatever reason it doesn't work for me.
1. Install .24 version (link see above)
2. Install cwm (4.0.0.8 version from S300-recovery.img 14/07/2011)
3. factory defaults from cwm
4. clear cache from cwm
5. clear dalvic cache from cwm
6. install smartoonay from cwm
Still only see my little Android friends
That's disapointing. Keep yourhopes up as Vache is working on a whole new ROM for the Iconia Smart. It's time consuming but it's going forward and it should be worth the wait
For the current ROM I think we tried everything (removing the battery and all) already and it might be an issue with you model.

I really hope he's able to give us something that'll work on all devices! I love Vache's work and was really disappointed when the only custom ROM we have didn't boot.

It doesn't work on yours either? Did you try it? Remember my device has a defect (touchscreen top is defective), so possibly it works on yours... (and I really did everything I can think of, including formatting system, etc., manually)...
My S300 also stuck in booting screen (Acer logo with 3 android idol) after flash the Smartoonay ROM...
I forgot backup my ROM before flashing it, does any one can help me how can flash back the official ROM without backup?

I actually had it before general release. Alas, my device just hangs until I take out the battery. Shame really, the root & cwm part worked great.

Hi edmund,
Just download the official ROM from somewhere (OS_Acer_1.000.24.EMEA.GEN1_A23G_S300), see above post. Or find yourself another ROM (I also used EUUs_Acer_S300_1.000.19_EMEA-GEN1_01.05.00 in the past, just google for it).
Connect your device with USB and install it using the setup.exe in the download.
In my case the installer crashed btw, because I have the android sdk installed which has a newer (incompatible) version of adb. Just make sure the PATH variable does not contain the ADB.EXE (use "for %I in (adb.exe) do echo %~dp$PATH:I" to figure that out).
Good luck!
Regards,
Nika.
Dear all,
I have been trying to get this ROM going but still no success.
I have compared the two boot images, and they are almost the same. It looks like it should be possible to run the Smartoonay rom with the stock boot image. That gives the highest success as well, because when I try to use the default Smartoonay rom it will get stuck at the first Android page (so it never shows the ICS boot animation). I also tried using the Smartoonay boot image with the stock ROM, but it then also gets stuck at the Android screen (see above image)
When I use the stock boot image, it finally displays the ICS boot animation, but it will get stuck in a bootloop. Usually caused by not clearing cache and such, but no solution in my case.
When I look at recovery.log, I do see one thing that I've never seen before:
Code:
Formatting /system...
[COLOR=Red][B]mtd: not erasing bad block at 0x08e00000[/B][/COLOR]
Done.
I wonder whether this one bad block may be the cause?
Anyone any other suggestions? Or maybe some instructions (a kitchen???) on how to make a new ROM like Smartoonay did? Any new Smartoonay ROMs to look forward to?
Regards,
Nika.

By the way... I fixed my screen by getting a new Touch Screen Digitizer for Acer S300 Iconia Smart Device is difficult to take apart (first take off top cover where the power button is in, which is a flat plastic, then take the screw out, then take the entire top cover off, remove two screws, open battery department cover, remove battery & screws, and then you can use a soft plastic pull tool to take the screen out...)

[Q] To root or not to root for update

Hi
I have a Samsung Galaxy GT-I5801 with me for past couple of years.
Its current OS spec are:
Firmware version- 2.2
Baseband version- I5801DDJP2
Kernel version- 2.6.32.9 [email protected] #2
Build Number- FROYO.DDJP6
My phone has become kind of slow, like for even basic tasks like opening call log or messaging app, it takes good 10-15 seconds. Sometimes it even goes unresponsive when trying to end a call thus causing call to continue thus carrier balance reduction. There are no 3rd party apps installed on it. Even updating the pre-installed apps gives the message of memory being low.
Now my query is:
Will flashing it to a custom ROM will improve its working at least in the basic areas of call and texting?
If so, then which is the most suitable custom ROM?
Is it necessary to root the phone before flashing it ?
Which tool is best/easiest for said purposes?
Please go easy on me, I've been out of the IT and tech game since past 1 year and bit rusty on these things

I would say yes. I don't know what is causing the freezes, but (beside that this could also be a hardware problem) a custom ROM should fix that.
Any GB-based ROM should do a fine job. There are also Froyo-based ROMs for our device. The CM7.2 build by marcellusbe does a very good job.
Nope. If you flash via Odin (Flash-Software for Windows) you just need a usb-connection. If you flash it via recovery, you may need to flash a custom recovery first.

I tried SuperOneClick but it failed to even detect my phone, let alone root. Tried rooting directly through phone by installing z4root on it. It too failed to root my device, just a blue screen saying "Running Exploit" with z4mod logo kept on displaying for 10-15 minutes, after which phone switched off itself. Had to power it back on myself. Tried it couple of times more but no success.
So now if I use Odin to directly flash the firmware to a modded one, would it work, considering the fact that the phone hasn't been rooted. More importantly, would it be wise to do so? Don't want to hard brick the device as its my backup device after my Xperia SP took a plunge in the water and now fails to even boot, just vibrates thrice and that's it.
Update:
Took a leap of faith with Odin and Cyanogen & now the device is rockin' like a grandma with a new hip replacement Lags no more, operation is smooth, but a 2nd minor problem has cropped up.
It now refuses to install any app from Play Store citing Insufficient Space. I changed the default installation space to external but still the problem persists.
Update 2:
For my above mentioned problem, looks like something to do with Gapps but I don't know what it is and what to do about it. Moreover as today I tried to make calls or send messages, I found out I'm unable to do so. The dialler dials after good 2-3 minutes of pressing/selecting the dial option for a number while message inbox is empty but it refuses the receive any sms citing Inbox is full. I thought just flashing the firmware should do the trick but looks like it just was the tip of the iceberg.
You can find the gapps (Google Apps - like Play Store, Gmail, ...) here:
http://goo.im/gapps/
Assuming you're on Gingerbread (CM 7.x) it's this package: http://goo.im/gapps/gapps-gb-20110828-signed.zip
Put this zip-file on your SD card, power off your phone and/or reboot to recovery. Navigate to "Select zip from sd card" -> select your gapps.zip and flash. Then "wipe cache" and "wipe dalvik cache" anywhere in the submenus Just to make sure the gapps get recognized correctly.
Another trick for expanding the internal storage is Link2SD. You need a 2-partition sd-card for this. 1. partition with FAT and 2. one with ext2/3/4
Link2SD will mount this second partition to the internal storage to expand your storage for apps and other system stuff.
You know... Getting the most of a half-dead low-end device needs a bit of geekiness
bad zip
Well I selected erase all data option in the phone which booted it into recovery mode. Here I cleared the cache and the user data. When I tried to install zip file from sd card it gave the following error message, "Can't open /sdcard/gapps-gb-20110828-signed.zip (bad) Installation Aborted"
What seems to be the problem now?
Update:
Tried again and this time it worked. Now everything is running fine. Thanks a ton for the help mate, can't express my gratitude through words.
I do want to ask one thing here.
If I install this, http://forum.xda-developers.com/showthread.php?t=1803180, will the JB experience be coupled with performance drop ?
Honestly Cyanogen has turned me into a junkie, now I want to try on the new but stable mods. Moreover as my Xperia SP is now out of warranty, I'm planning to get it fixed and then root and flash it too!

OmniRom Twlight Zone - WTH is going on?

This is my first attempt into breathing life back into my tf300t I've had for almost 3 years. Hardly used it do to the continuing blog down that always occurred and the lack of updates by Asus eventually led me to unlocking/custom rom/rooting and then soon thereafter to here. Knowing nothing about the process and procedures, although somewhat computer literate (I started on a TRS-80 in the early 80s), I did the cursory research for the uneducated I decided to try the lollipop variant of Kisskat 5.1.1. I used TWRP to make a recovery back up and then wiped/flashed/booted. Fooled around with it some but discovered a few quirks. For one, the zone closest to the Asus logo was rather warm to almost hot even if you throttle back the performance. But more importantly after installing my apps via the play store I began to notice some media issues. For one, the video was a bit choppy (I use VLC player) and my mp3s seem to be inoperable on almost any app. (I typically use Fusion and EZ Folder Player but nothing seemed to work). I kept getting issues that seemed to be related to the recognition of folders of file types. Often telling me an mp3 file was not a recognized folder or that the file type was not recognized or in some cases (EZ Folder Player) I simply could not change directories to access files. Any help in these areas may put me back in the KissKat Camp... at least until the thing catches on fire... then we can roast marshmallows and have a camp sing along.
Before jumping on the forum I thought I'd try a more simple fix - try another rom. Tried OmniRom and while not as zippy (or hot) it seemed stable enough to go with for a while. Did the Gapps recommended for the latest pop rom and the superSU file. Loaded my apps from the play store. Then decided that perhaps I should back up all my apps after having went though applying all the correct passwords and what not. Read the Titanium Backup was a the best option. Made an initial internal mem backup of all apps then read that I could create a zip of the apps to use as a recovery method off of an SD Card which sounded the better option for me (seems far more secure). Then I felt that I was at a juncture where I should test my backups before moving on the custom folders and docs and so forth only to find out a problem was in the works when the time came at an inopportune moment down the road. Well I discovered a problem. I booted into TWRP and wiped then used my recovery to bring it back to the last known state before my first flash of a custom rom (not sure if this is even a necessary step but it seemed like it certainly couldn't hurt). Then boot/re-boot to TWRP, and having read a full/complete wipe was necessary I wiped everything (Full data format - then wiped all options in the advanced wipe section other than my SD Card where I was holding my files for flashing). Then flashed (1)OminiRom 5.1.1 (2)Recommended Gapps package (3) SuperSU, and - this is where I may have had a bad moment - the Zip file generated by Titanium Backup Pro - Is this even where I can flash install this file???Was kinda lost there. Well... I think I then tapped the TWRP button for wiping/clearing the Cache / Dalvik Cache having read (although also having read to the contrary) that this was necessary to avoid a bootloop. Then I rebooted and arrived shortly thereafter at the OmniRom Boot animation of the droid bot blinking eyes and wiggling his antennae which is as far as this Rom, which once loaded and operated fine, will now go.
I have since tried several times to reload the rom only to the same end. I have even tried the latest nightly on the rom. Same result. Tried the latest version of TWRP (2 updates since the 2.8.5.0 I initially installed with) and both updated TWRPS were riddled with problems for me - Most importantly they would not reboot - had to force close via the power button only to have TWRP reboot to itself and the process start again. As well, TWRP would not do anything as no partitions were mounted nor could I mount them - just red error messages on the console screen when I attempted to do even a simple wipe. Obviously I was getting deeper into the omniRom twlight zone.
KEEP IN MIND - this is the weird part - I COULD and still can (1) Boot to TWRP and recovery to my initial recovery file I made of JB 4.2.1 stock from Asus (if it didn't suck with lag I would have stayed there to begin with) and (2) I COULD ALSO FLASH THE KISSKAT CUSTOM ROM but as I said I had issues with it which led me to try OmniRom which I thought was a good choice until the problems.
At this point, as I sit here - I have used fastboot to reinstall the TWRP 2.8.5.0 (since it was what worked initially) and I have TWRPed to the recovery JB 4.2.1 and then wiped everything using TWRP - Data Format and all advanced wipe options less my own SD Card. Another issue - I tried the latest release of KissKat #26 and this time, in addition to the problems noted earlier, I cannot seem to mount the SD Card as it is now unrecognized by the TF300t (although it worked fine in the #25 build).
I am at an impasse and any help with any of these problems would be greatly appreciated. I just want to get a decent functioning custom rom on this tablet to get some more life out of it.
Thanks in advance,
Dog.... from somewhere near the outer limits of the realm of... the twlightRom

Always about 100% CPU usage... :/

Hey, I got a little problem with my Tab2 10.1 - with different ROMs and even with stock firmware, I always get nearly 100% CPU usage by "other processes".
Im getting that information by the app "System Panel 2". And the tab runs like sh*t... What can I do now? Im not that new to rooting and flashing, but something like this never happend to me... :crying:
Its a Tab 2 10.1 WiFi (P5110)...
I tried:
- (clean) flash of different ROMs
- (dirty) flash of old backups
- wipe of everything (incl. Internal Storage etc...)
- flashing stock FW with Odin
- tried phh's superuser instead of SuperSU
- tried in terminal "setenforce 0" (or something like that)
Some flashes run the first minutes like always and some of them are from the beginning sh*tty to use, cant even open settings app...
Hope anyone got an idea for that problem :/

- (clean) flash of different ROMs
- (dirty) flash of old backups
- wipe of everything (incl. Internal Storage etc...)
- flashing stock FW with Odin
- tried phh's superuser instead of SuperSU
- tried in terminal "setenforce 0" (or something like that)
Some flashes run the first minutes like always and some of them are from the beginning sh*tty to use, cant even open settings app...
Hope anyone got an idea for that problem :/

Finally I got it!!! I dont know why, but it was my SD Card... I unplugged it and boom, no problems anymore...
I wiped the SD Card and now I can use it like before without this weired problem. Huh...
SD card formatting stopped high CPU on custom ROM. Thanks!
Thank you!
This solved my problem with a custom rom (NAOSPROM 7.1.2 december with OpenGapps pico) on my Samsung Galaxy Tab 2.
After installing gave me alternating high CPU after a reboot. One time reboot gave a low CPU and than next time high.
'Simple OS Monitor' (great tool) just showed system_server around 16-17% hardly ever lower. Stopping almost all non essential system apps and all user apps. Didn't make any difference. Even removing SD card.
A network reset seemed to do something, but hardly.
But then after formatting SD card, putting back the files I had stored there, except the Android .secure android folder, I rebooted and all was well. CPU usage of system_server went from 17 to 1 % and total CPU to normal
So Samsung Galaxy Tab 2 works well with NAOSPROM 7.1.2 custom rom ... but don't forget to format your SD (when you experience high CPU usage).
Just in case somebody finds this information. Like I did yours.
