[Q] Nexus One won't downgrade or boot! - Android Software/Hacking General [Developers Only]

So i decided to buy a Nexus One and tried to root it. I followed some online instructions and sucsessfully unlocked the bootloader, but it didn't help at all! The dude i bought the phone from had all up to date so i had to downgrade it to 2.3.3 and when I tried to flash the update it says "instalation aborted" what the h*ll? After trying to get it to work I flashed some other stuff and now the phone won't boot! it automatically goes into the bootloader. So far I tried factory reseting, wiping the cache, EVERYTHING!!! Not even the custom recoveries would work. Any help with this? I just need to downgrade it to 2.3.3 so i can root it but it's just not working

[Q] Cant Install any custom ROMs

Ok, this is weird, a while ago i didnt had any problems installing any kind of custom rom, used CWM while wiping everything... eveything was OK, ROM worked OK, etc... But one time i installed a ROM (Slimkat) and i lost signal, tried to use my recovery of stock android but it didnt work, so i tried a lot of things untill i got bootlop without being able to install anything since some files were missing, bad luck
After that, i just reflash stock 4.3 and upgrade from there 4.4.2, everything fine again... except that i cant install any kind of ROM, every ROM says "installation succesful" but everyone is stuck into bootloop.
While i havent tried ALL ROMS i have tried the same ones i was using (Nexus G+, LiquidSmooth and CM11), so i guess this problem is coming from my device.
On a side note, i tried to factory reset, but no luck... it shows the Android working but it inmediately turns the screen off, and then it shows it again and then off again... in an infinite loop
Same problem!
Bump.
I just got my Moto G yesterday (European XT1032), updated to 4.4.2, unlocked bootloader, rooted with superboot and flashed Philz Touch CWM.
Seems I have done everything by the book, wipes included, but no luck. I tried Slimkat, Paranoid and Codename Lungo (latest builds as of 3/12).

Hmmm... Pay attention to which version of Bootloader you are using.
You might want to try both 4.3 and 4.4 to see which one would work.
Extract the motoboot.img from the stock .zip image for your phone, then flash with mflashboot flash motoboot motoboot.img
Good luck!

Thanks. I'll give that a try. Is there a way to check bootloader version on the phone? If that doesn't work out I'll start from scratch and report back in this thread..

Hmmm.. I see there is a version number on mine, 41.05 dated 2013-12-06, but I'm not sure if that's the version or not.
And yeah... if changing the bootloader doesn't help, you probably would have to restore from the stock image and start over..
Got root and custom roms working after I 1.) downgraded to 4.3 and 2.) flash TWRP (instead of CWM).
So I'm not sure what the problem was. Besides the two main rooting methods (superboot and custom recovery), there are some other methods described on the forum specifically for people who already did a international variant OTA to 4.4.2. and one that is absolete (here) but apparently works for some when the two main methods fail.
However I'm still not sure if this solved everything. I am not sure if I can flash Cyanogenmod (which is 4.4.2) over a 4.3 firmware. Maybe I need to manually flash a 4.4.2 radio or something... Gonna check that out next...
EDIT: No need to downgrade. Not sure how it works but two main root methods (superboot and custom recovery) didn't work for me. Somehow I got stuck in boot animation. Just installed TWRP instead of CWM after Kitkat firmware (EU Retail) and rooted (/installed Super Su) from there. Everything works fine now.

[Q] HTC one Mini rooted need to get back to stock CID ROGER001

Hi,
I am new to android and have rooted and have custom TWRP recovery installed 2.8.0.1. Phone works fine then after some time (couple days) if i restart its goes into boot loop, which can be stopped by a factory reset from tarp recovery (tried just clearing the cache and Davlik cache didn't work.
Would like to either upgrade to a new rom or go back to stock and use an OTA.
Cant seem to find the correct build has to have the 631 in it, i assume from my research.
**EDIT**
Solved the boot loop issue by flashing an updated version of supersu and installing.
Still am looking for stock recovery so i can do OTA for the newest updates, no luck so far.
If anyone knows where I can find a stock recovery or anyway to get back to stock for this phone with these specs let me know thanks!

Boot loop after flashing roms

Hey guys.
I just got an M8 and obviously had to root and rom it. I have my phone rooted and s-off. I am running 4.4.3. I have tried to flash CM 12, multiple nightlies, and also android revolution. No matter what I do, I get stuck in a boot loop. On CM it gets stuck at the android head bootloader, and with android revolution it gets stuck at the red verizon screen. Then the only way to fix it is to power the phone off, remove the sd card and sim card, since that's the only way it will let me boot into recovery, then flash my stock rom back on it. I'm not sure what I am missing here. I used Sunshine and paid the money and it gave me s-off but it didn't give me root. I used towelroot for the root access. Any advice?
I'd suggest ruu back to stock 4.4.4 or flash 4.4.4 firmware since your running old firmware.. Threads are in development section
Save the manuals!!!

Custom rom and OTA are very different things. For installing a custom rom, you'll need a custom recovery, for a custom recovery you'll need to unlock your bootloader first. You CAN'T unroot your phone if its hung in a boot loop.
You can download the stock firmware HERE
Thank You for replying
I have downloaded the stock firmware and i have tried installing it but that is where the problem occurs the phone says that it is an OTA update package and cannot resume the download because the phone is rooted.
