General :: SGS2 (GT-I9100) Recovery After Flashing Kernel?
Feb 25, 2012
When I got my phone at the end of last year I rooted it using a Chain-Fire kernel - v 4.2, I think. After flashing, it worked perfectly, since when I have flashed the old bootloader to get my USB Jig working to remove the yellow triangle and flashed a patch again to allow the USB Jig to reset the binary counter.
I have very much wanted to install and get the new Sky Go application working.
What I had to do was flash the Stock kernel for my Stock Rom - I have never messed with my Rom - it is Gingerbread 2.3.4 in a CPW phone here in the UK.
Doing the flash and installing Voodoo OTA (to temporarily hide my root) has been enormously successful
Now then to my query....
The original Chain-Fire mod v 4.2 installed CWM.
After of course cancelling the "hide root" function to show my phone as rooted once more, I went to do a backup, using CWM but it refuses to work. It says my kernel needs v 5.0. Obviously the Stock Rom I flashed to get Sky Go working has thrown CWM some what.
I have downloaded Rom Manager from the Market but this seems not to work either - it starts to work (reboots) but then halts with the following messages: -
E : failed to verify whole-file signature
E : signature verification failed
Installation aborted
What I would like is some way of installing a backup previously made before flashing the Stock kernal and also to make a fresh backup now.

For the last 5 days I am experiencing extreme battery drainage(Android OS nearly 100% Battery Usage ). Back when it began I did not install anything suspicious or battery consuming software. I never go full screen brightness, and all unnecessary apps are either deleted or disabled. I have tried Factory Resetting, Wiping all possible caches, systems, internal/external SD cards. I even tried manually deleting all folders from my PC. I have tried installing custom kernels, roots and even stock ROM. Right now I'm with stock ROM with CF root.
Phone state: Model number- GT-i9100; Android 4.0.3; Baseband v. i9100XXLPS, Kernel v. 3.0.15-i9100XXLPQ-CL223505 se,infra@SEP-94 #3; Built number IML74K.XWLP7. And here is what I get from the battery report :
i41.tinypic(dot)com/1j9nae.png
I have tried full discharge and charge to 100% and calibration. Even cleared the battery stats It just doesn't work. I am using Nova Launcher. Even after going back to TwLauncher I am still getting 98% Android OS usage. I don't use Data Mode and Wi-Fi isn't always on. When charged and calibrated at 100% at 21:00pm, in the morning at 9:00am phone battery is completely empty and shut down.
I'd like to use the stock ROM, with a nice battery stable kernel & still with Nova Launcher. NOTE: This is still happening with a NEW battery.

I hear that some kernals are better than others and I assumed they change when you change your ROM but I'm not sure. I feel like I would have better battery life with a better kernel.

I did a research regarding Flashing Kernels and Roms and currently i have installed Cyanogen 9.1 for my device.
1.Will I be able to update my phone and bring back to old ICS firmware via SUS once i brick my phone(I have already unlocked the bootloader via fastboot method)?
2.Evrytime when i flash the Rom(say CM9) i used to flash kernal(boot.img) for the respective rom.Is this necessary all the time? Will i able to flash a GB rom on ICS kernal(I am afraid to give it a test)?
3.Regarding CM9.1 which i have installed ryt now,I am satisfied with the performance,but i want a stable ROM wud make me happy with a better battery life unlike CM9.1. Any GB/ICS ROM which wud have a stable performance with descent battery life.
4.After using GB for a long time,i was very much addicted with the Phone pad kinda keyboard,but when ICS came into picture everything vanished,Smartkeyboard Pro is no gud,Touchpal is conjusted,i want the exact GB keyboard in ICS.
Phone: Xperia Ray
Bootloacker:Unlocked
ROM: GB Stock Rom

So I've been looking into flashing custom kernels, and I can't seem to find an answer to this question. Basically, I'm wondering if the kernel remains after installing a new nightly, or do I have to reflash the kernel every time the ROM updates?

I have an xperia X8 with some naa kernel and xperiadroidx 6.1.The thing is that with this custom kernel and ROM when i put a SIM from another network carrier, the question asking for the SIM-unlock code input is not showing up. (this appeared before when phone was in stock state).Is it possible to do it without re-flashing to stock?
...or i have to put back the phone to stock? What is the easiest/safest/best way to do this? using the restore option in "PC companion" SE app? Is it only needed to put the stock kernel and ROM, or Do i also need to re-lock the bootloader?
I don't need the whole explanation, just a little guidance, just a few tips to know what to do, then i can google/search myself for the specifics on how to actually do it.

Rom Manager tells me "Goophone i5 does not have an officially supported ClockworkMod Recovery yet. Have you installed a ClockWorkMod recovery manually?"... If I say Yes it asks me to confirm Version 2.x or 3.x+. I don't know if a CWM was installed manually. What should I do?
I can't see a recovery file on the SD card.

Is it possible to change the recovery of a kernel! I mean manually change the recovery version! I have a Xperia P and I am having problem mounting emmc on Philz recovery, so I wanted to change the recovery to CWM recovery 6.0.1.2 of my favorite kernel.

I flashed Omega rom today for my galaxy note 2. It uses Aroma installer which i think could be the problem. Basically I cant boot into recovery. The rom is also very laggy where people on its development thread are praising it stability! The device will stay on the 'Samsung galaxy note II gt17100' bootscreen when i try to.boot into recovery.

note before attempting any of this that rooting does void your warranty. I also am not reponsible for any damage that is done to your phone but am more than willing to help you solve a problem in IRC. See my signature on how to get on #ally IRC channel. I do not actually use the Clockwork Recovery (i use drellisdees).

My Samsung Note 10.1(N8000) got stuck on boot screen at stock. No recovery only download mode. I don't know why, it was flat for about 2 weeks before I noticed.
Roms always and still flash successfully if I get the right version of odin, i think i have about 15 different odins from trying to fix this.
Things I've tried:
1.Flash stock rom
2.Flash custom recovery
3.Flash different versions of both 7+
4.Re-partition and repeat 1-3
5.Wipe the memory and repeat 4 with many many roms
why my tablet stopped the first time and why no roms are working to recover it. What is happening here? Is it corrupt memory or motherboard etc hardware? Is there a god .pit file or god rom that could work to make something happen? What should i try now?
This shows a successful flash which had no effect on the tablet afterwards

I did not brick a tablet without having a cwm installed first and a nandroid backup. The tablet is an allwinner a23 not in some peoples opinion worth a lot of effort to fix. We have an identical tablet with the same firmware. If I root and install a custom recovery on the unbricked tablet can that zip be flashed without a custom recovery? I have looked about a bit and there seems to be conflicting opinions on this. The only prob I can see is the stock recovery may not have the option to wipe the dalvik cache.

I have a verizon samsung galaxy s3. I'm planning to upgrade to the kitkat 4.4 but I was going to do a nandroid backup first. Using rom manager I am attempting to go into recovery mode but everytime I try I get this message:
System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for support.
I disabled the knox sensor and then totally removed it and it's components. I don't know what else to try.

so i just find a new way to reboot to stock recovery on samsung galaxy ace plus GT-S7500 without flashing another custom recoveru like cwm or something like that
many people say that we cant access the stock recovery on galaxy ace plus because it have some bugs or something else.. now i found the way how to do that
just follow the simple guide how to do that :
1. reboot it using volume + and volume - ~> home button ~> power button
2. click and hold both volume button then the home button then the power button..
3. if the phone gets turned on so u need to keep hold that button until the recovery showed up (when it showed up and its get turned off again so u need to hold all the button again until it get rebooted to recovery)
4.if u get rebooted all time its not a big problem again .. all u need is just hold all that button until the phone gets turned on and release the power off button and hold it again until u boot it on recovery mode.. and done u booted up on recovery mode (im not responsible if ur phone gets bootloop or something else)

I flashed + rooted (strangely in that order, which means I must have rooted my phone ages ago.. and then locked my bootloader after flashing..?)...
I do have Rom manager installed... but I don't quite recall how I ended up flashing the stock rom onto the phone..
Anyways, as I did seem to reset my phone, I upgraded all the apk packs and I'm pretty happy with the speed upgrade + ext2 internal space expansion.
As I now want to create a nandroid backup, so I can always come back to my current status, when I want a clean reinstall..!
My main question is that as I seem to have skipped creating a CWM recovery... if I do so now, will I loose all my data and go back to the basic stock rom?
The problem I'm facing right now is that I'm unable to boot into the recovery mode using either "adb reboot recovery" or the power on + vol buttons / menu button. (which means that I don't have the recovery mode installed.....)
So.... will I loose my current upgrades + phone settings (reset into factory mode), if I flash the recovery mode?

Does system recovery "Wipe data/factory reset" resets custom kernel to stock?
I'm asking this because im noob, and I want to try JellyBlast for Galaxy GT-S5570I. It has two zip files to flash one is ROM, and one is custom kernel. If I do something wrong I'm afraid that I won't be able to restore nandroid backup.

I am on twrp recovery version 2.1.3 and to upgrade to 2.5.0.0 I used the Google .im app but even after the message showing that recovery was flashed successfully, when I reboot into recovery I still see the 2.1.3 twrp only..So I tried flashing it with terminal emulator but it didn't work.This error shows up every time failed scanning partitions failed with error : - 1
I tried putting the .img file in the root folder as well but it didn't work..I tried naming the root of sd card as storage/emulated/legacy, storage/ emulated / 0, /sdcard, etc but it keeps on giving this error every single time!

So I was having a problem with my Optimus V (Virginmobile) and I couldn't send or receive texts. I did a factory restart thinking it would work but then found myself at the recovery menu. When I try to flash xionia_cwma_12518.6.zip it says E:cant find update script. When I try and flash CM7.2RC1_VM670-BobZhome-052012 it installs and when I reboot i get taken back to the recovery menu.
In short; My Virgin Mobile Optimus V is stuck in a recovery loop that I am unable to get out of due to an error while trying to flash ROMs/ Custom Recovery.
The error reads at the end of all attempts: E: Can't find update script.

I recently rooted my Evo using UnRevoked 3.2 and flashed Fresh 3.3 on it. I'm generally happy with the results, the upgrade seemed to fix some problems with random reboots and screen locks I was having on stock (I'm thinking that moving a lot of apps to SD may have helped, as I seemed to be always low on memory).
In any case, I do think the phone is a bit "laggy" after the update. I downloaded FPS2D and checked my FPS, seem to average right around 50fps with std dev of 9. It seems like many people are getting much better screen performance using the custom netarchy 4.1.9 kernel. I'd like to give that a try but I have a couple of basic questions...
1. I will do a nandroid backup and Titanium before I flash, but I noticed that restoring apps last time was a drag...I use FolderOrganizer and it's a pain to get them all set up the way I had them. Does flashing the kernel wipe your phone clean? How much app/Sense restoring would I have to do assuming all goes well? I'm assuming that flashing the kernel has little to no effect on installed apps or Sense screen layouts...he cried hopefully...
2. I'm assuming here that Fresh 3.3 is compatible with netarchy 4.1.9, correct? Also, I saw an indication that netarchy 5.0 may be around the corner...is it better to wait? Or is reflashing a kernel that easy so there's no reason to wait?
3. It looks like an overclocking app is included in the netarchy kernel? Is it necessary to tweak the profiles, and if so what are the recommended tweaks for best performance? I have some experience with this coming from an overclocked Palm Pre, but I care a lot more about my Evo...I don't want to hurt it!
4. Battery performance is less of a concern than screen performance for me...I have chargers everywhere. Still, I'd like to get the best battery performance I can. I believe there may be "rogue" services on my phone that are eating up the battery (for example, I use Exchange ActiveSync and I turned it off recently because sync problems were causing it to stay on in the background). What's a good way (or app) to identify rogue apps/services and kill them?

I have a rooted Droid Incredible, running stock 2.2 and Hydra's 1.15 ghz kernel. I found a ROM called "Light Speed," and I'm wondering if I should try it out. Here's the link: [ROM] Light Speed - Droid Forum - Verizon Droid & the Motorola Droid Forum I'm thinking of the sense version. Do you think it will work? Also, it says it features KingxKernel #6. Is this a stable kernel? How many ghz will it go to? Any other tips before I flash? (Ex. wipe, backup)

So I was under the impression that you could use ROM manager or ClockWork mod to install a custom kernel that I had downloaded to my SDcard. I downloaded a low-volt, overclock kernel and I have discovered that I don't quite know to flash it to my phone.
