[Q] Why do no changes occur after I flash a kernel? - General Questions and Answers

Hi, first post here so please mind my ignorance. I recently rooted my Sprint HTC One m7 and installed the latest TWRP recovery. Since I found out that I have no /system write permissions and I wanted to use apps like the Xposed framework, I decided to flash a custom kernel which disabled the protections, because I didn't feel the need to get a new ROM. So, I am running the stock Sense 6 ROM on 4.4.2 with the stock kernel 3.4.10-gf22c859 and S-On. I tried to flash flar2's ElementalX 14.12 for Sprint. I created a nandroid backup and cleared my cache and dalvik. Then I flashed the kernel, and the install went fine. It said it was successful, and once again I cleared the cache and dalvik. I rebooted my device, and it started up, updating all the apps. and I rebooted the device again like the installer had said to. However, when I tried using the new features like logo2menu nothing happened. I checked what my kernel was in the settings, and it had not changed. The only thing that did change on my phone was the fact that all of my paid apps said they had not been installed, and when I did try to install them, I would get an error saying my SD card did not give them permission to do so (or something similar to that, I don't remember the exact message). I thought that it was a problem with the kernel, so I restored to the nandroid, and flashed the Kangaroo kernel the same way I did with ElementalX. Once again, the set up process went fine. When I booted my device, I was greeted with the same results as before. Apps updated, kernel didn't change, paid apps gone. I am really confused with what is going on. I feel like I am missing something obvious (This is my first time installing a kernel on an Android device). Any help would be greatly appreciated! Thanks is advance.

I think I broke it.

I just got this phone yesterday and immediately installed CM7. Thinks were going well, except for the random restarts at the lock screen and some apps not working. I read that Faux's CM stock kernel improves stability, and I hoped it would fix the restarts.
I read the directions thoroughly, wiped out the cache, wiped out the Dalvik cache, installed the kernel, and rebooted. It got stuck at a black screen, but I read that it does take a while, so I left it for about 10-15 minutes before removing the battery.
I wiped all caches, including user data, and reinstalled CM7 hoping it would fix whatever kernel problem just happened. Now it freezes at the blue LG screen.
I've tried several different caches that are all supposed to be comparable with my phone, and after installing them (after wiping all caches and /system each time) I'm stuck at the blue LG screen. I also tried flashing the entire phone to stuck, but to no avail. Installing the GB Kernel stock got me back to the black screen, this time flashing a brighter shade of black periodically, but still after 20 minutes, nothing happened.
I'm going insane after spending all day searching these forums and Google. If there's anything I can try besides installing kernels and reinstalling CM7, please let me know. I'm an idiot and didn't backup before I installed CM7 the first time, and every backup I've downloaded gives me an MD5 checksum error. At least I still have access to recovery. Most results I pulled up with searches brought me to people who lost their recovery menu as well, I'm not sure why I can't fix this even with the recovery menu still intact.
Keep in mind that you have to clear cache/dalvik right AFTER you have flashed the kernel, before reboot.
At this point, i would suggest to do a full wipe (clear data/factory reset, caches and also format system under storage and mounts). Then flash your flavor of CM7 and while still in CWM, flash the kernel of your choice, DON'T REBOOT, but clear cache/dalvik. Reboot, let it sit for a while and you should be good.

That worked! I came across that earlier, but I downloaded a similar package with a flash.bat that didn't fix it. Sure enough, I'm back. Thanks!
Make sure you downloaded his CM7 version and not Stock kernel.

You welcome, I've added info on how to install custom kernel too
What are the usual behaviors while waiting for the phone to boot up for the first time with the new custom kernel? I downloaded the latest March nightly of CM7 (the latest April build gave me a bad file error while trying to install for whatever reason) and Faux's LGE Pre-OC/UV Kernel Version 013, did the proper order of installation, and it's been sitting for about 15 minutes now at a black screen that keeps flashing on and off. With USB plugged into my PC, I'm hearing a rapid "plugged/unplugged" sound loop with each flashing screen. Will I have to do the whole ROM Recovery tool process to try again?

You can't install custom kernel on nightly release. Use RC 7.2 and yes do the rom recovery and back it up so the next time you can just restore to any rom that works on your phone.
This may sound crazy, but I feel like I CM7-proofed my phone. Ever since I messed up that first time with the kernel and used the recovery tool, I can't get CM7 loaded anymore. I got 7.2 RC and installed it with the kernel the proper way, and got stuck at the LG screen.
So I used the recovery tool again, then NVFlash, wiped data/cache, installed the root file, then tried installing just 7.2 RC by itself. No luck.
I used recovery tool again, then NVFlash, then wiped data/cache, then used restore to bring it back to the stock + root that I made this morning before trying 7.2 RC and I'm back... so I went to CWM again and did wipe data/cache, and installed the SAME CM7 file I installed with yesterday morning which worked fine at the time, the latest stable release (7.1), and I'm still stuck at the LG screen.
This makes absolutely no sense. EaglesBlood installs fine, so it's not a problem with custom roms, I just don't like EaglesBlood (and EaglesBlood also froze when installing a custom rom the correct way as well). I'm tempted to just stick with the stock GB 2.3.3 + root since it works, I'm just missing the features I had yesterday of CM7 before I installed that god forsaken kernel.

I Think you are missing a one step, Wipe Dalvik. Ok let start from the begining,
First restore your phone to stock, let it boot. Root your phone and install CWM. Install CM7.2 RC rom and let it boot. Go back to the CWM and follow this instructions:
Wipe Cache
Wipe Dalvik
Wipe Batt Stats
Install Kernel
Fix Permissions
Reboot
all these steps are important. I was using CM 7.2 RC with Faux's kernel without any problem and it worked flawlessly
I just tried again with those instructions, and I still can't even get CM7 to boot up for the first time.
- Recovered my phone to stock using rom recovery tool
- Let boot, got to android's home screen, shut down
- Used One-Click-Recovery's "Flash CWM 5.0.2.0 Internal and External SD ROM" feature to install CWM (I'm assuming this is the proper way. I learned this from a YouTube video and it helped me to root my phone and get CM7 working the first time)
- Booted into CWM, wiped user data and cache, installed root-g2x-su-2.3.6.3.zip
- Restarted just to be sure (though I have tried just flashing CM7 after the root without restarting) and got into the android home screen just fine after I had to go through initial setup again. Though oddly enough my Google Apps were still present. They weren't present the very first time I rooted my phone, I had to install gapps.
- Shut down phone, went into CWM again
- Wiped user data, wiped cache, installed CM7 7.2 RC1
- Rebooted
- Stuck at blue LG screen for eternity.
I'm using the same root file as I did when I rooted my phone for the first time, and I've tried using this same method with the very first CM7 file I successfully installed and ran, and I'm still stuck at the blue LG logo unless I stock recover again and stick with stock. Rooting works fine, I've been able to run rooted apps on the stock rom, I just can't install any version of CM7 again for the life of me.

I've done what all three of those videos have shown. These methods work for other custom roms just fine, just not CM7 which is what I want, regardless of what build I use. Which rom is the closest to CM7? I tried EaglesBlood and I noticed a lot of changes I didn't agree with, I didn't toy around with it long enough to see if I could get it working like CM7.
EDIT: Even tried Nullifier Dual Wipe, still stuck. Just... wow.
EDIT #2: Now EaglesBlood doesn't even want to run, also getting stuck at the LG logo after recovering, wiping data/cache, and flashing the rom. It worked fine last night, I just erased it so I could give CM7 another shot and didn't have enough space on my SD to have a backup of that AND my rooted stock.
EDIT #3: Did the recovery/root/flash method again, going from fresh stock to flashed CM7, and this time it sits at the blue LG logo for a few seconds, before restarting and going back to the white LG logo. I wiped the cache though to prevent a bootloop, and I think most bootloops occur with the CM7 logo anyway.
There's no chance of any files being on the micro sd that could be causing the problems, could there? And is there anything else I should be wiping/formatting these tries? Like maybe rom recovery doesn't wipe EVERYTHING out, and I still have remnants of other attempts still?

No chance. Nothing will be left over when you wipe your phone. Your SD card is only accessed when you tell CWM to do so. Take your phone back to stock. Do it again this time try either a froyo rom or ICS rom. Then go back wipe everything and install CM7. Sometimes you have to take the long way. after flashing my phone a bazzilion time I learned this the hard way when I couldnt load EB ICS anymore. Had to run GB to get to ICS. Try it in reverse or from a step below and it should go through fine. IF it doesn't, you might have to use ICS instead, which may be stuttery, but works damn well.

I'm wondering why he still has the issue. YOU CLEAN CACHE BEFORE FLASHING KERNEL/ROM UPDATES!!!

For God sake, just flash a random ROM to get access to inside your phone.
1. DIAG your phone OFFLINE with v21e baseband (phone will automatically restart)
2. Let it stay for 5mins after that
3. Use your phone for 15mins
4. Root using 1Click
5. Install CWM
6. Install your ideal ROM + GAPPS (if needed) via CWM
7. Reboot
8. Go outside your living room and watch TV for at least 15mins
9. Reboot your phone into CWM and flash your ideal kernel
10. Enjoy!!!
You better know which ROM/kernel to choose from. Period.
How to upgrade/downgrade your baseband? Do some search, please!
Sent from my LG-P999 using xda premium
I'll do a flash of Froyo or ICS and possibly some baseband research tomorrow. Considering my luck getting a simple rom flash to work, I don't feel too comfortable dealing with the baseband.
A friend was brave enough (somehow) to let me root and install CM7 on his phone, he has the same phone as mine. I got CM7 7.2 RC and Faux's DM UV working like a dream on my first try. Tried it on my phone after recovering it, same problem. So it's a problem that exists deeper on my phone, not with my methods.
The NAND restores for GB and Froyo give me MD5 checksum errors, and the stock zipped rom of GB gives me an installation failed error, so I'm thinking a zipped Froyo rom won't work either, but it might be worth a shot.
Tried Weapon and MIUI too. No go. If I don't get stuck at the blue LG logo, then I'm stuck in a loop between the two LG logos or stuck at a flashing black screen. 8/10 times though it's the blue LG, I think the other errors may have actually been me forgetting to wipe my cache when I was flustered.
I'll try ICS, and hopefully won't get to a point where I have problems installing things I used to be able to, since that seems to be the pattern. After that I finally give up.
I FIGURED IT OUT! Well, sort of. For the hell of it, I downloaded CM7 7.1.0.1 through Rom Manager and it installed fine. It downloaded it to my internal SD, so I hooked it up to my PC to copy the 7.2.0 RC1 to my internal SD and tried installing. No go.
So I went on my phone's web browser and redownloaded 7.2.0 RC1 that way directly to the phone. It works. So somehow, roms I copy from my PC to the phone appear to not work, yet apps and kernels still do. I'm running CM7 7.2.0 RC1, downloaded through my phone's web browser, with Faux's DS UV kernel, copied from my computer. After four days, I finally found a workaround, so I'll stick to it. Whatever works, I guess. I can try reinstalling my USB drivers, but I can probably get by with a combination of the phone's web browser and ES File Manager w/ LAN if need be.

Rooted, Backed-Up, Flashed to Synergy...First timer...How to load backups now?

So I left Apple, came to Android, rooted my VZW GS3. First time I've ever done anything like this, so I'm new to it. I backed up EVERYTHING using TiBu, did the IMEI backup, Full system/image backup using CWM, unlocked bootloader, etc. Then I flashed to Synergy r46 (august 20th - yesterday's release).
Now I'm at work and my back-up pulled my contacts via Verizon's server, but how do I get back EVERYTHING else? SMS/MMS logs, call logs, apps, app data, etc? Do I need to download TiBu again (fresh from google market) and then load my backups off my Ext-SD card, or what? I guess I'm a bit confused as to where my TiBu items were even stored/saved...I assume it was the ExtSD card, otherwise I would have lost them all upon flashing to Synergy, correct?
Any help to get all my apps and data back on my newly Synergized phone would be awesome!!!! Thanks in advance!!!
Yes download titanium and then point it to the directory you had your back ups saved to (its sd card by default, and which is your phone storage btw) then tab to backup/restore click the check, then once your app data populates, and select run next to restore apps and data.

I used titanuium backup pro to back up all my Apps and system data. And when I flash a new rom I just redownload titanium pro and it automatically restores all my Apps and system data. It is the easiest app I have used. So to answer ur question.....back up ur apps with titanium then after flashing a new rom go and redownload titanium and restore your system data and apps or just apps alone if that's what u prefer? Does that answer ur question or would u like more detailed instructions?

Another very nice feature of Titanium Backup is its ability to pull data from CWM nandroids. There have been a few times where I was quick to flash a new rom without doing a backup of my apps. This has saved me much time from having to re-flash the nandroid backup, backup via TB, then re-flash to the new rom.

This is one thing that scares me...I don't quite understand what's being wiped or how to perform a full wipe. I hope I don't do this on accident on day...When I flashed the ROM, I basically booted into CWM recovery and installed from there....I was unable to install by opening the ROMs ZIP file via ROM Manager. When I tried to install this way, it failed.
Can somebody confirm if I flashed correctly, just to put my worries to rest? Here's how I did it...
I backed everything up, unlocked bootloader, and tried to install Synergy r46 via ROM manager, but I had problem. I had the ZIP for the ROM downloaded to my Ext-SD card, like the installation instructions say. I then opened ROM Manager and went to "install ROM from SD card." The phone rebooted and opened in CWM to install...But kept having problems finding some "path" or something.
So I decide to wing it and rebooted into CWM. I cleared davik cache(sp?), then user data, then navigated to my Ext-SD and selected the ROM ZIP to install. Now, everything seems fine and it says it installed successfully, but I still think I installed in a way that wasn't described.
Is this a legit install and is this how most people flash ROMs, from booting directly into CWM, or should ROM manager have worked for me via "install ROM from SD card???" If so, why didn't ROM Manager work for me?
Rather urgent question: When I restore my items, do I want to click "RESTORE MISSING APPS + ALL SYSTEM DATA?" ill this restore the bloatware that was on my phone prior to flashing????? If so, is there any way around it
Thanks a bunch! Just waiting on an answer to the later questions before I restore.

I am wondering if you didn't do the full wipe. If you are using CWM v6.0.1.0 then there is no option labeled "user data" it is "wipe data/factory reset" which is the full wipe like I mentioned.
As far as doing it correctly, as you may have already noticed there is more than one way to do about anything. Personally, I still use CWM v6.0.1.0 and flash the zips there.
P.S. I see you are enjoying your freedom of losing your apples!
Also, tell me how your r46 is working ... I have held off at r23 while they are playing around with kernels and ramdisk tweaks for awhile.
Hi, I'm pretty much in the same boat as the OP coming from an iphone and this is my first android phone. My problem is that all of the synergy roms (r39, 46, 50 and 1.7) I tried were unstable and kept rebooting randomly. I unlocked the boot loader and believe I did everything right. Did I miss a step? I restored back my nandroid after several attempts at Synergy. I like the responsiveness and tweaks of Synergy but I couldn't deal with the random reboots. Sometimes it would just continue in a boot loop too.

I'm fairly certain I did "wipe data/factory reset," I just wasn't sure how it was labeled when I typed that out, but that's really ringing a bell. I think I may have gotten the errors before (using ROM Manager) because I hadn't factory reset? Seems to me I'm good to go! However, my question regarding TiBu still remains.
Edit: In regards to informing you about r46, I'm not sure what to report as I've never used a previous Synergy and have no idea how to compare, other than to the rooted stock ROM. I have heard reports of battery life being worse than the stock ROM, and I can confirm this. I've barely used the phone since I flashed to Synergy and it's dropped 15% battery life in ~3 hours. Seems faster than before but I'm unsure.

I started getting that sort of behavior so I just restored back to my stock rooted backup and reflashed Synergy 1.7 r23 and then reflashed the theme I'm using. I thought my issues came from other modifications I had tried so I will try to remember to report back to this post tomorrow and tell you if I'm still having those similar issues or if I'm stable again.

Was 1.7 r23 supposed to be a really stable release? I read through some of the Synergy thread and didn't see anyone having the issues I had. I felt like I was doing something wrong.

I have never had a hot boot or boot loop using any version of synergy. I've been running it since 1.3 and flashed last night's rom as well. What method of unlock did you use for the bootloader unlock? Did you see the custom kernel loaded into phone settings?

I have never had a hot boot or boot loop using any version of synergy. I've been running it since 1.3 and flashed last night's rom as well. What method of unlock did you use for the bootloader unlock? Did you see the custom kernel loaded into phone settings?

I used the EZ-unlock app in the play store. I did see that a custom kernel was loaded however when i flashed back to my nandroid (stock rooted) I am back on the orignal kernel. Would the way I rooted have an effect on the reboots? I used the non flash method by Noxious Ninja.

I agree I have yet to have Synergy boot loop although I'm still on 1.7. I would try to wipe cache and dalvik cache and see if that helps or you could be over clocking to high.

Was 1.7 r23 supposed to be a really stable release? I read through some of the Synergy thread and didn't see anyone having the issues I had. I felt like I was doing something wrong.

I don't know the answer to that specifically. All I know was that I was stable before another modification I made (that said it wouldn't work but I tried it anyway). Since restoring from backup and reloading Synergy and theme I have not seen any weird rebooting anymore.

I'm not familiar with that method. I've only used Odin, even when I did have to redo everything I used Odin to stock de-bloated rooted .md5 then CWM'd from there.
So I'm giving it another shot on r50. I made sure to clear dalvik, cache and data. After flashing It gave me the reboot problems again. I installed system tuner to change the cpu back to 1.5. Maybe it's from the overclock but we'll see how it goes. Is everyone leaving it overclocked on 1.9 not having issues?

That may very well be the issue. 1.9ghz is a very aggressive overclock, and i wouldn't be surprised if was unstable on a good number of phones. Synergy's supposed to boot at 1.5ghz max by default - I don't know whether that was successfully implemented. I personally think it's silly to OC such a capable phone, anyway. Back in the days of the Droid 1, an overclock from the stock 550mhz to 800mhz-900mhz was an enormous improvement. Today, the only thing OCing the S3 gets you is a <10% improvement in Quadrant, more heat, possible instability, and no perceptible difference outside of those silly synthetic benchmarks.
Anyway, in this thread, there seems to be a fair bit of confusion as far as what's what in the android partitions. I'll give you a short rundown.
"aboot" is what's referred to here as the bootloader. It checks to see whether the next partition in the boot sequence, "boot", is authorized. When you unlocked your bootloader, you overwrote aboot with a version that does not perform that check.
"boot" contains your kernel. If your ROM has a custom kernel, it contains a boot.img to overwrite boot.
"system" is the meat of the OS. This is primarily what ROMs flash.
"data" contains all of your apps and settings. When you perform a factory reset, you're reformatting data. If you're flashing a ROM that is significantly different from what you're on now, some of those old settings and data can cause errors, force closes, random reboots, and boot loops. When in doubt, wipe data before flashing a new ROM. When going from one version of a ROM to a newer, very similar version of the same ROM (nightly to nightly), you probably don't need to wipe data, but make a backup just in case. dalvik-cache is also in data; if you wipe data, you've automatically wiped the dalvik cache. It's redundant to wipe data and then wipe dalvik cache.
"cache" is just that, the cache partition. Clearing it won't make you loose anything, at least not anything Android won't silently replace.
So far it seems to be pretty stable on r50. I installed system tuner and brought it down to 1.5 Ghz. I'm not sure why 1.9 is set to default. Doesn't seem like a good idea to me. Thanks all for the help/advice.

[Q] Help, stuck in bootloop with CM 10 ROM

So I was able to successfully root my AT&T HTC One X and decided I wanted to install the CM 10 ROM (1st ROM install). I did all the data backups with Titanium, downloaded the latest zip files from cyanogenMod (both the 12/13 and 12/14 nightly versions), transferred them to my phone, booted into recovery (TWRP), did a back-up, did a system wipe, flashed the ROM and then did a reboot. However, when it boots it gets stuck in the boot-up screen (bootloop) and doesn't do anything. I have read on this and it keeps saying to wipe system data again and flash the ROM again and it keeps doing this. I want to install this ROM, but I need some help. Any suggestions on what I did wrong?
Note: I accidentally posted this in the Android Q&A section, so I apologize for the double post. I just think this is probably the best place to get my answer.
Did you flash the boot.img?
I did, but incorrectly the first time. I flashed it the right way and everything is working good. Then only problem I have now is when restoring from Titanium Backup it gives me an error from a process called com.android.phone (I think that is what it said). So I wiped it again and rebooted and everything is fine. I can reinstall all the apps, but what could cause that? Could it be some of the data backed up doesn't cooperate with this ROM? Either way I love the CM10 ROM.

if they are backups from sense, that *MAY* cause problems, but don't quote me on that. I don't use sense, can't say for sure
OK, maybe that is why. Not a big deal since I haven't had the One X too long. Thanks for the help guys.
Good to know

[Completed] Need help restoring stock android (Galaxy S6 SM-G920I)

I recently purchased a factory unlocked Galaxy S6, and I decided to go ahead and install Xposed Framework (this is after I flashed XtreStoLite Deodexed). I installed XtreStoLite correctly, and I also installed TWRP.
After I went to install the Xposed Framework, I got stuck in a bootloop. I believe that I may have installed an incorrect version of it, although I'm not sure. I'd just like to reset the phone to its defaults - I did not have much saved on it to begin with since I decided to go ahead and mess with it encase of this happening. I unfortunately forgot to back up, since I thought that installing Xposed would be as easy as XSL. I'm able to provide any more information that anyone needs; I'd just like to get the phone working again.
I have already went ahead and loaded into TWRP and wiped the Dalvik, Cache, and I also formatted my data. I'm not sure what to do now, because it's still bootlooping. Any help would be appreciated.

Hello,
Since you still have TWRP, you can flash the xposed uninstaller zip. You may find it here Xposed official thread

Bootloop after trying to install custom rom

Hello!
I did search some topic with bootloop problems, and the thread with my ROM itself, but haven't find any solution.
I was trying to install custom rom and end up with a bootloop. Still can go to recovery/download mode.
I was following instruction from this thread: https://forum.xda-developers.com/ga...-android-nougat-7-0-beta-3-zpkk-odex-t3507499
I have SM-G930F Flat. Enable OEM activated, when system (6.1.1?) was going on. Unfortunately I lost my backup. ;(
When flashing TWRP, probably didnt uncheck restart options, but didnt remember what happened next. I think I just flashed it once more to be sure. Then POWER+DOWN, POWER+MENU+UP got me to nice menu of recovery.
But when I tried to install _no-verity-opt-encrypt-2.2.zip_ file (or even create backup or wipe data), my phone tells me that it couldn't mount /data (couples of times, actually).
Ignored it and proceed with wiping and installing of no-verity and ROM itself (with another wipings among resets). Ended up with bootloop for more like 15 mins and clearly something is wrong here.
I tried to check to install newest modem and csc in aroma installer, but it didnt help.
What am I doing wrong here?
Thanks in advance!
Tom
Weird thing. Glitch has gone. After trying to install with new modem&csc (and it didnt work), turned phone down for ~1h. Now error with mounting /data is gone. Installed everything and new ROM is working nice. Interesting thing, will try to close this thread.
