[Q] Kernel flshing - Xperia Arc Q&A, Help & Troubleshooting

Hey folks,
Im new to the whole custom roms & kernel business but already experiencing the benefits and enjoyment behind tweaking my Arc S.
Ive managed to unlock my bootloader and get Jelly Sandwhich 5.0 running using the Lupus v5 kernel but decided to upgrade to the latest version of the kernel which is 5.2.
Carried out all the usual steps and reinstalled my custom rom only to find my phone hanging on the boot logo.
Luckily I had a backup so could easily restore but am wandering what it is I have done wrong as the last few times ive been messing around with it, it worked like a charm, am I supposed to re-flash to stock kernel before flashing to a new kernel?
Would ask in the developers thread itself but am stuck with my nooby post limit of 1 so cannot reply or give thanks to all those involved.

If you've reinstalled a different ROM then you should have cleared data and caches, if it's stuck on the updated kernel then it's possibly a kernel problem. And you don't need to flash the whole ROM if just updating the kernel.

No problems reported in the development thread so must have been an issue at my end. Noticed I was on an older flashtool version so will update
to latest version wipe everything and try again.

Desire reboots every 10 minutes or so after installing custom ROM

Hi
Hoping someone can help. I recently rooted my Desire. I then installed LeeDroid and everything looked great. Then my phone rebooted itself and started rebooting approx every 10 minutes even when not in use.
I had wiped all data and caches before installing and made sure I had the correct radio version installed.
So I decided to wipe again and install the CM ROM instead. Exactly the same thing happened - it booted up into CM fine and then after 10 mins or so decided to start rebooting.
So I then restored back to my stock ROM and the phone was fine - no reboots since.
Has anybody else had this issue? Is it a problem with the phone or the ROMs or something else? I find it hard to believe it's the phone as it's fine when the stock ROM is running.
HELP!!!
Never had reboots like that, not on a single ROM. I followed everything as they suggested (ROM) thread. Check your radio version, if it is compatible with the ROM. Try a different kernel.
Sent from my customized HTC Desire using TTP
Sorry if i'm thick....how do i try a different kernel?
The radio version is compatible.
nobody else?
Serach for kernels here. Just flash them via recovery as the ROM. No wipe needed.
How do I know which one to try? Also, will this affect getting my restore back if it goes wrong or does my backup include the kernel?
Sense kernel for Sense ROMs, AOSP for non Sense ROMs.
Nandroid backs up the kernel as well. Which to try? I suggest the latest Neophyte 1000mv, because:

[Q] HTC One V (CDMA) continuously boots after flashing ROM

Any resolution to this problem? This has been reported in several threads (link 1, link 2, link 3, need I give more?)
I'm also experiencing the same problem. I installed Paranoid Android (per instructions here) and am now experiencing the same problem. After flashing, the phone continuously reboots. I am using an HTC One V (CDMA) from the US. I also flashed the JB 4.1.2 gapps with the ROM flash process.
When it boots, I receive two errors: "Unfortunately, android.process.acore has stopped working" and "Unfortunately, Contacts has stopped working". When I lock the screen, it reboots. When I try using it, it reboots after 30 seconds. If I just leave it alone, it reboots.
I have also tried several kernels with this same ROM (kernel that comes with the ROM, SuperSick [found here], and stock CM10) and they all just produced the same behavior.
I've looked all around. Some possibilities are: bad kernel, memory (RAM or otherwise) running out, bad install of ROM, or something no one has yet to define. I don't think its a bad kernel because this happens in 3 different ones. I don't think it's a memory issue because I lowered the CPU clockspeed and the phone has plenty of storage memory, and I've also flashed AOKP with the same results which rules out a bad ROM install.
I've wiped cache, system, data, and dalvik and followed all instructions as given to get a completely fresh installation. No avail. I realize that the One V isn't very popular, and there is only a limited amount of support for it but could anyone shed some light as to what the problem could be?? Perhaps some of the original devs who made the ROMs can help out us lowly fools who can't get it to work? I thank anyone in advance for being awesome and at least trying to help.
You may have to flash the old RUU. Look in the General subforum for a thread about phone rebooting after one minute.
sounds like you did the OTA update and have the new radio version, you need to RUU back to stock and dont get the OTA.
I'll try.
Thanks both of you! I will try flashing the RUU and I'll make sure to not install the OTA update. I'll post later with my results.
...
So... I flashed the RUU on the phone again. I again carefully followed instructions on how to flash ROMs (AOKP and Paranoid) and it simply doesn't boot. AOKP's ROM only starts up to a black screen. Paranoid boots to the boot screen animation and just hangs... I've used stock kernels, and tried the SuperSick kernel with both. No progress. Any other ideas?
Try the latest version of cm10 with the latest version super sick kennel. That's what I'm running. AOKP has a few versions that boot to a black screen. If you want AOKP use the latest stable version.
Awesome!

Riggerman0421, thanks a ton for the suggestion!! It worked! Despite not being able to use the other roms, I think I can settle with using CM10.

You have to RUU your device back to the original radio version; it was changed when you accepted the OTA update. That means that you're going to have to flash it to complete stock (no recovery, HTC Sense, booloader relocked, etc.) using the RUU. The forum I found that had all of the different RUUs was deleted unfortunately. You'll have to do careful research for the RUU for your specific device. I only know that Virgin Mobile in the U.S. uses the Sprint towers, so the RUU I used was titled "RUU_PRIMO_C_ICS_40A_Sprint_WWE_VM_1.08.652.6_Radio_1.00.00.0521_2_NV_VM_3.46_0503_PRL61008_release_262414_signed". Just a quick search on XDA and found this forum that has a download link to the RUU you would need for VM [CDMA] phone (read the comments); you can also look around yourself to make sure you have the right one.
You can find specific instructions on how to RUU your device at this awesome forum. It should only take, literally, 15-20 minutes.
After that is done, you will need to unlock your bootloader again and then you're ready to move on to bigger and better ROMs.

So, this happend to my htc and I ruu'ed back to stock, after continunously trying to install roms with constant bootloops. I did the ota update again. So if I want to install a custom rom your saying DONT do the ota after ruu'ing then install one after rooting?
I've got a similar issue (virgin mobile HTC One V)
I currently have TWRP recovery installed, and I attempted to flash the jellybean CM10 as well as the AOKP rom, and I got as far as the unicorn and I actually manged to get the phone to boot to the main screen with all the icons, but it would constantly reboot after being on for maybe a minute
I tried flashing everything back to stock including restoring a backup I had previously taken with TWRP, but no luck
I also tried flashing the stock rom downloaded somewhere here on XDA and I even flashed the stock recovery, but all I got was constant rebooting.
it would get as far as the startup animation and then reboot indefinitely
I'm at a total loss here. I've seen a few links with some resources that look like they might have been helpful (like on this thread) but the links are dead, and I also read somewhere that HTC was putting the kibosh on a site that had some stock roms.
I'd prefer to get jellybean working on my phone, but ultimately, I just want a working phone.
I've followed the process of installing the rom - some instructions said to flash the boot img before flashing the rom, some say after
I've tried both methods
I went into recovery, mounted the usbmsd and copied the rom, and used recovery to install the rom after having cleared the cache, davlik cache and wiping the data (factory reset)
I also installed the gapps package after the rom, but I don't think that's critical to getting it to just boot.
The OTA update reboots were fixed in the latest 4.2 SickleKernels.

I think I'm having the same problem. The phone boots, gets as far as the "this build is for development purposes..." and then hangs for a few minutes and restarts, over and over. The flash with fastboot seemed to work fine and reported no errors.

Yes. Do NOT install the update if you want to flash another ROM onto your device. Use the RUU to get the device back to factory; this will restore the original radio version. Then go through the steps to unlock the bootloader, root, and flash your ROM as desired. There are other forums which explain the mentioned processes better.
BeyondExistence says that this is fixed with a "4.2 SickleKernel", but as far as I'm aware there are no JB 4.2 ROMs for the HTC One V. Maybe a little more information would be in order?
Bheadrick:
I'm not quite sure what you mean when you say you flashed the stock recovery. The One V doesn't have a recovery when everything is stock.
You will have to RUU your device back (have you read any of the posts in this and other forums??). The process will reinstall the stock rom, relock your bootloader, remove the recovery, etc.
I recommend that you use Paranoid android's rom with the latest SuperSick kernel. Its been my favorite and most stable build I've used.
Sent from my Nexus 7 using xda app-developers app
So I found what BeyondExistence might have been talking about (for those of you who care/are currently having the bootloop problem and would rather go with this route). Its called RhythmicRom. This is a 4.2.2 ROM and it has some cool things for users switching from Sense to a more-pure Android [Link here]. Its based off of CM10.1 for the One V and it includes the BeatsAudio app (which most ROMs don't, as far as I know).
The reason I think that this is worth mentioning is because whoever runs into this bootlooping problem can simply SKIP the RUU process and just move onto this ROM. Hit thanks if this helped!
Newest OTA update.
As some of you may have seen, there's an even newer OTA Update available through the stock ROM. As always, this will cause problems when you try to flash a different kernel, resulting in bootlooping (can anyone who has done the newest update confirm?). Anyway, I've also read that this update also updates your hboot (which, since I haven't and will not apply the update, don't know why it would impede you from flashing any other ROM/kernel but it does) and radio version.
I've looked for additional ROMs who try and make their builds compatible, but so far only RhythmicRom has done anything worthwhile (in my opinion). His latest v 1.3 build will be out soon, and I highly recommend it.
If you flashed both OTA updates, then please be sure to include that when making any post.

I got my One V at the end of December and did the OTA update at the beginning of April. Last week, I decided to try messing with loading some different ROMs and have encountered all of the problems you've mentioned (e.g., boot-looping, inability to RUU back to stock). I have successfully gotten RhythmicRom to load using this OTA_support.zip (which has been incorporated into the regular release since I flashed it). I have also gotten the most recent version of PACman v22.1 to run (using the same kernel as RhythmicRom) without boot-looping, but the performance hasn't been great (browser crashes frequently and it seems like the launcher has to restart a lot). User demi_fiend has said that the PACman ROM will work using the CodefireX kernel from user BeyondExistence.
I had also tried to revert back to my stock CWM recovery, but it had the boot-loop problem too. However, demi_fiend has also informed me that you can revert to a stock backup by using the boot.img file that is located in the backup folder. I haven't had the chance to verify this, but I wouldn't be surprised if it were true.
It's a bit of a pickle being unable to revert back to previous radio versions, but there is hope that some of the devs will incorporate this issue into their new builds.

Did you flash stock recovery and lock bootloader before running RUU?

I had flashed my stock recovery (although it was still boot-looping), and I did re-lock the bootloader before running the RUU.
I used the instructions found here.

Flashing JB Roms causes bootloops

Hello guys!
As the title says, I keep on having boot loops after flashing any custom JB Roms (Jedi, LiquidSmooth, CM Nightly, Slimbean). I'm not new to flashing roms (I got LG units though, SU660 and KU5900). When I tried flashing ICS Roms, I don't have any problem. But I want JB that bad!
I followed KonstantinKeller's thread of restoring/recovering from a bad flash (going back to GB), rooted following Melvin's thread. Then did all the prerequisites..like the common wiping of data, clear cache & davlik. But then again after flashing JB roms listed above, I keep on having boot loops!
What did I do wrong? This ain't my first time flashing (first time on this phone -T989- though)
I read some posts with almost the same problem, but I don't think I found a solution for this. Any good soul that can extend their help is highly appreciated. Thank you in advance.
I got a bootloop before when trying to flash JB roms and what I did was restore to original state (using the bad flash recovery technique), and then not rooting it but installing cwm through Odin and dirty flashing the Rom in cwm. Once it flashed I used it for a few to make sure that everything was working correctly. Then I got the goo manager app and got twrp. After that I followed all the steps in the OP (Jedi jelly) and flashed the Rom. Now I'm running Jedi jelly 3.1 perfectly. Hope this method helps.

are you using darkside scripts to wipe? because they will cause bootloops

is there any way to reverse the loop that the darkside wipe is causing?
it REALLY sounds like the recovery u are using is TOO OLD. Make sure u are using the latest version of twrp (2.3.3) to flash all jellybean roms.
TWRP is backwards compatible and touch capable, so if you're worried about flashing GB or ICS ROMs it'll do the trick just fine
it is however a requirement for flashing all 4.1 ROMs.
Basic install instructions:
make sure u have root
download goo manager from play
open > menu > install open script recovery
agree to everything, but make sure t989 is in the downloaded image name
reboot to recovery u should see twrp

[Q] Custom Rom Wizards crashing

Hey guys i have a samsung i747 from rogers and i'm trying to install custom roms. I've obviously rooted it and installed CM recovery and downloaded roms and gapps. So far i've tried liquidsmooth 2.8. Avatar Rom. Cyanogen. but nothing seems to be working. Every single one of the them keeps telling me that my setup wizard had crashed and my gapps weren't working. I earlier had a Status 7 error installing cyano and avatar so i flashed d2att's 07.05.13 kernel, but that didn't seem to help. I tried running a different version of the clockworkmod recovery too. I've hardly ever "dirty" flashed. Someone help me out here i hate custom roms!!!
Wipe
Data
Cache
Delvik Cache
and Factory Reset.
Make sure you're flashing the correct GApps for android 4.2.x
Flashing a kernel has nothing to do with a status 7 error.
A status 7 error points to a outdated recovery or bootloader.
You should get ANY errors.
If you hate flashing why do it??
I honestly don't get that...
If you're here to make your phone to look "cool" you're in the wrong place.

I would get TWRP recovery.. wipe dalvik / factory reset. and re-flash your rom.. I'm on Rogers as well and the status 7 error means that your recovery / bootloader is outdated.
So start by getting the most recent TWRP. I got it from goo.
btw: if you don't like custom rom, i suggest going to the sammobile site and getting your factory firmware. Use Odin to reflash back to stock. That should solve your hiatus towards custom roms...

thanks guys but idk i just tried flashing a custom rom at 4.1.2 and then went up from the there and it was fine... for the status 7 i just adjusted the coding for it so it didn`t have to check the model and this was typed up like at like 2 in the morning where i`m from i meant to say i hate stock roms LMAO:silly:

[Q] M919 Rooted But Boot Loops With Custom Rom

I tried flashing a nightly of CM12 on my M919 after no problems for almost 2 weeks. After flashing, my phone was stuck in boot with the CM logo. I tried flashing previous versions of the rom wiping and clearing each time. All I got was the CM logo. I finally decided to start from scratch and reinstalled stock(4.4.4) with ODIN 3.07. Phone booted right up. Rooted the phone with CF-Auto-Root (KTU84P.M919UVUFNH7) with no problems. Ran it for the day to make sure no issues. After feeling comfortable, I downloaded and tried flashing CM11 Snapshot M12 since it's based off 4.4.4. Boot loop again. I tried CM12 with the same results. I'm using CWMR 6.0.4.7. I've tried newer versions of both CWMR and TWRP(I don't remember what versions they were). I'd like to go back to using 5.0, if possible. I'm not sure if I've missed a step in rooting, since it's been so long that I rooted/flashed this phone. Right now it's running stock 4.4.4/M919UVUFNK2 and rooted. Any suggestions as to what I could try?
That nightly may have borked some files causing a problem, the nightlies are usually full of warnings about possibly causing boot loops or lockups and always recommend a nandroid b/u before flashing.
A nightly is a way of trying something out on other people's phones to see if it works well enough to add it as an update to the regular rom build.
If your that desperate for a nightly you need to follow the thread for a couple of days and see how others do with it.
If all you see is "I flashed the nightly and boot loops all over the place, don't bother, otherwise you find yourself in this thread.
Try a factory reset and flashing again,
also get a newer CWM recovery 6051 (if not mistaken) but stay away from the nightlies.
If you really need a reliable phone that works all the time and doesn't windup dead, just keep your stock rooted rom. And lollipop will be here soon as an update, probably by mid-march, the you'll have all the lollipops you want.
