[Q] bootloops after flashing rom - Nexus One Q&A, Help & Troubleshooting

I just got a nexus one for $35 that i plan on using mostly as an mp3 player. I rooted it using the one click method but it's still S-on. Part of my issue is that booting into recovery using CWM only works maybe 25% of the time. Not sure why that is. A couple times I've been able to flash a rom via recovery but after seeing the X screen, the phone bootloops on the next splash screen. This has happened on two GB roms - MIUI and CM 7.2.
Any guess on why this happens? One reason I want to flash a rom is that the camera doesn't work so I'm curious if it would work in a different rom.

Before flashing a ROM, clear cache/ dalvik-cache from recovery. If you don't do these, then you will see bootloops.

I had been doing that through rom manager but just did it through recovery. still bootlooping.
I wiped cache but did not factory reset

If you are changing ROMs, its always advisable to do a factory reset in addition to clearing cache and dalvik. Try it

Best advice is to skip ROM manager and always do everything manually in recovery, this has never been a problem for me
And just because, I would suggest using 4ext recovery as in my opinion it is by far the most superior recovery... Just saying

Unfortunately, I've tried flashing manually via recovery too...still bootloops

Check md5sum of ROM (maybe bad download)
Make sure you wipe fully (manually in recovery or with fastboot)
Make sure you meet requirements of ROM in op (as in you flashed gapps if needed or you have a large enough system partition etc)

yeah, i haven't checked the md5's but it's odd that it's happened with both official miui and cyanogenmod. i did wipe cache and dalvik. i think i'm just going to give up. i'd do a factory restore but don't want to do that because then i'd have to root my phone again. i rooted the phone using a Vista computer but now I'm back home and my computer runs windows 8. from what I can tell, installing the android SDK is kinda complicated on W8.

Factory reset is needed and will not mean you have to reroot your phone, this is something that would be done before each flash, in fact the cleaner the wipe the less chance of an issue.
Also there is no need for the SDK to root (but its easy to get for windows 8 anyway and tools such as fastboot and adb are very handy... Also there are other ways to get these tools without the SDK) but all that besides the point, these are your steps
Nandroid backup
Wipe everything as clean as possible
Flash ROM and anything else needed (gapps etc)
Reboot
This is the procedure you should follow for any ROM flash for any android and never a need to reroot in between
Best of luck

I really appreciate the help. the reason I mention the SDK is that my computer doesn't recognize my phone unless I install the SDK and the associated drivers. So I'd hate the wipe my phone so that I can flash a rom, but then be unable to flash a rom because I'm not rooted!
But you feel confident that if I factory reset, I won't loose root?

I factory reset daily! You'll be just fine, when you factory reset and wipe all partitions you are following the proper procedure to change roms. When you flash the new one you are sure to still have root access

well, did a factory reset last night but i'm still having the same problem. I'm at a loss.

[How To] CWM Recovery

With the new boot loader unlock it comes time to use a recovery other than safe strap. The easiest way to flash a custom recovery, in this case, clockwordmod recovery, is to simply download ROM Manager and use it to flash the Motorola Photon Q version of CWM Recovery. I flashed it and booted into it and haven't experienced any problems as of yet so for those looking for a custom recovery straight out of the gate, this is for you.

I haven't actually tried yet flashing a ROM but since I'm on stock and don't want to flash white yet I haven't had the opportunity, as long as its flashing to the device it should work with no problems

So far, i have installed the cwm for the photon q like you, and made a back up through it. Im going to see if it will restore from it as well. ill keep everyone updated.:good:
:edit: I sucessfully backed up my stock JB rom, wiped everything, and restored everything back and everythings perfect... I dont know what else to try before attempting to flash using the photon CWM. any ideas?
I uses the photon q recovery to backup & restore, and haven't had any issues yet. No ROM flashing for the time being, just haven't tried it yet.

Did you try to go back into CWM and wipe everything again after the boot loops? That sometimes helps when it is boot looping after an install.

I'm Stock Again, Restart always sent me to fastboot with a failed flash error, I could back out of it to the pizza ROM each time however I don't want to depend on my phone booting incorrectly so I used RSD and I'm stock again, I'm going to give it another try tonight.
UPDATE...Reflashed everything started over and everything works PERFECT Yippie!!! I'm very pleased!!!!

So what was your full procedure? I want to try this and try to install CM10 later.
From what I read, you installed the Photon Q CWM, installed Pizza through that, got boot loops, flashed back to stock, then installed Pizza again?

Fastboot was kicking errors and was boot looping into fastboot with firmware flash fail, I found however I could start into AOSPizza in DB mode (Safe Mode) , so I did that, charged up the phone 100% then used RSDLite and Reflashed Stock current firmware, it however does not re-lock the bootloader as some have mentioned might be the case in other post's, from there I started up the phone,turned on usb debug, used "motochopper" to root it, then installed Rom Manager from the market, flashed clockwork to device with the Photo Q CWM , copied AOSPixxaV1.zip ( The ROM ) and GappizzaV1.zip to the Phones internal storage not on the external SD memory card, from there went to clockwork mod on my atrix opened up the program and selected to reboot into recovery, went to the mounts and storage then select Mount System then go back then install zip from sd card then choose zip from sd card, then scroll to your rom and select it and it will flash when its complete you will go back and go to reboot system now, it will ask you if you want to bypass stock recovery on boot select it and your phone will reboot into AOSPizza......Have Fun!

Phone broke, Help!

Hi, I recently tried to root my Galaxy Exhibit, but now it's broken, nothing will load, it all force closes. My home, menu and search buttons do not work, I tried to restore it by using factory reset, but that just messed it up more. I plunged it into Samsung Kies, but it won't recognize the device. How can I restore the phone back, unroot, to factory settings.
This is what I did, first I downloaded TWO custom kernel (or roms, idk the difference.) The first one worked like a charm it was the root stock 1.8 but it was too stock, I wanted ICS so, I restored and I put a different rom/kernel in and booted it up, and boom everything is messed up, my kernel version has not changed, I tried using cwm recovery, but it didn't do anything.
Thanks
Sent from my LG-E970 using xda app-developers app
Well easy fix, in cwm wipe system or ROM 3 times wipe cache/dalvic cache. Then you can flash ICS and gapps, be advised there is no further development for ICS so I would suggest any 4.1 ROMs or even the 4.2 ROMs. Make sure you flash gapps
Sent from my SGH-T679 using xda app-developers app
this is why people need to do research. if you dont know the difference between roms and kernels dont flash

Nexus One wont boot past boot animation and needs rooting

So I've had a nexus one for a while now, and recently I decided to root it. I managed to unlock my bootloader and flash clock work recovery. I then made a stupid mistake of trying to flash a rom before rooting my phone or backing up my rom. When I power on my phone now it just freezes on the boot animation. The only thing I can do is access recovery. What is the easiest way to root my nexus one in this condition or is there anyway of flashing a rom, hence fixing it? Preferably from a Mac but I may be able to get access to windows or linux. Thanks in advance

Turn off your phone, pop your SD card in your comp and copy the su.zip into it. Pop it back into your phone, boot into recovery and flash it on. Voila, root access!
Then wipe cache, dalvik-cache and all those and reflash the ROM again. You should be good to go.
BTW. I hope you are flashing a ROM which needs a stock HBOOT. Coz for JB ROMs, custom HBOOT is needed. Cheers!

Thanks a lot for the help! Do you know of any JB or ICS roms that do not require a special HBOOT? And where is the download for the su.zip you mentioned? Thanks a lot
All newer ROMs have a larger system partition requirement, why not flash an older gingerbread ROM that doesn't require black rose until you get the hang of flashing.
You don't need to flash superuser or busy box or anything first, just wipe all in recovery, flash ROM (plus anything else needed like gapps) reboot

@demkantor is right. Basically you don't need su.zip coz most ROMs will have that flashed in already. I think the problem you were facing was because you did not wipe your cache/dalvik-cache and data before flashing on the ROM.

[Q] Flashing kernel through recovery problem

Hi.
After unlocking my HTC, installing recovery and a custom ROM (ARHD 13.3) I have a problem with flashing kernels through recovery. Every time when it starts, phone reboots into system, just after the flashing starts, withough flashing the kernel. Any ideas?
Anyone? :-\ tried reflashing Rom with full wipe, tried other roms, changed the recovery...always the same.

Sounds strange! What kernel are you trying to flash? Did you also make sure your download's MD5 is correct; could be a bad download.
Yes, md5 sum is correct. I'm trying to flash anything strange is that after full wipe and reflashing Rom I can flash anything before first boot. After first boot can't flash zip files, like Rom cleaner or kernel. Phone always reboots just after flashing starts.
Once I've found that someone had such problem and formating something through adb helped...but can't find this info again
I tried flashing almost every kernel available.

I think Rom Cleaner should be flashed before first boot anyway, but not the kernel. Are you clearing cache and dalvik before trying to flash?
Yes. I even clean cache through sdk :-\ yep, the Rom cleaner should be flashed before first boot, but anyway it shouldn't reboot even later as I think.

Weird
Just for the sake of trying, a couple of ideas:
1- wipe the cache from recovery (not fastboot) and also wipe dalvik, then immediately flash kernel
2- perhaps there's a permission issue with the zip(s) / folder(s)
EDIT: perhaps you need to update recovery?
I reflashed recovery, tried CWM, TWRP...same on both think about going back to stock with RUU, then trying everything again from the start:-\
First advance...tried.
Second...U mean fixing permissions? Don't know if it's related to that problem, but of course will try.

Though I don't think custom recovery would have issues with permissions (since it's su privilege), it could be the folder where your zip files are doesnt have rw permission, and the recovery attempts to access the folder, is unable to, and therefore just reboots.
Try putting the zip file in a different directory (or maybe even the root folder) and try again.
In root folder? Don't understand where exactly...tried to place it on different locations in storage.

Obvious question, but the kernel is for your version of Android isn't it? You're not flashing a 4.3 kernel on to 4.2.2?
of course not I'm on android 4.2.2 and flashing the 4.2.2 kernel version
---------------------------
as for now everything's ok. Frankly speaking I didn't do anything new. reflashed recovery for the third time i believe, did the full wipe also few times, flashed arhd, rom cleaner and the kernel one by one and it works...for now
---------------------------
and no..it's still the same. After first boot, I rebooted into recevery, tried to flash different zip and what....and reboot just after flashing:/ it makes me sick...:/
Thanks to one and all. I was facing the same issue of being unable to install the Bulletproof kernel on my HTC One having ViperOne 4.2.0 custom rom and TWRP 2.6.3.3 recovery.
I followed the advice here and wiped 'Dalvik cache' and 'cache' and (without rebooting) directly dirty flashed the Bulletproof kernel which did the trick.
Hope this helps someone else too.
Got the same problem. Tried with TWRP 2.6.6.3, 2.6.6.4 & actual CWM with failed tries to flash kernel,bootscreens,themes & the 360 camera fix.
Also tried to flash these recovery via fastboot and at least the m7&m7ul versions.
It happens suddenly
Btw: i'm on an tampered,unlocked hboot 1.54
Any help or ideas are much appreciated
