[Q] Stuck at boot screen with the nexus logo - Nexus One Q&A, Help & Troubleshooting

hello, I hope one of you can help me because I've been trying to fix my nexus one for over 4 days now ... after hours of unsuccessfull attempts... I have decided to ask for help, so heres the deal...
I got this phone from a friend.. he had tried to flash the phone (i think) and broke it.. I saw a radio update and a file starting with the name "eViL" in the SD card. I have tried to flash it several times... even deleted the two files in the SD card and 'tried' to restore the original ROM refering to the tutorial in this link..
http://forum.xda-developers.com/showthread.php?t=614850
I downloaded the ROM from the rapidshare link which was given there; All the steps worked fine except 'fastboot erase userdata' .. This one gave me an access denied error.. however, still my phone wont boot. gets stuck with the nexus logo and the lock icon.. I cant go into recovery mode.. when i try, it goes back to the boot screen and gets stuck there...Please help me fix my phone...

Need some expert help,

So today i tried updating my Three locked Xperia X1i, Donwload went fine but it decided to crash half way through installing the update and is now stuck on that Colourfull Lined Screen. saying "upgrade ROM code error" Now ive tried restarting the download and the updater says it cant read the phone and wont do anything! can someone please help on the situation.
Providing you HardSPL'd first just get yourself a KOVSIMG.NBH file (for the XPERIA, I recommend Sutyi's SECOND ROM) put it on your microSD card and start up in boot loader mode. You can search how to start in boot loader mode easily enough.
I havent HardSPL'd, I just bought the Xperia and thought i should officially update it, Didnt know it would cause this. there should be some easy fix to it.

[Q] htc hd7 firmware update gone wrong

I recently tried to update HTC HD7 firmware after a hang issue. I had hard reset the phone and the phone now boots in bootloader mode. I cannot exit the bootloader mode. Also, I may have tried flashing the device with RUU_Schubert_hTC_Asia_WWE_2.20.841.02_Radio_5.65.09.11a_22.44.50.15_NoDo
When the ROM version of the phone is 2250.09.12302.707. Now my phone is unusable. It starts in bootloader mode any attempt to flash it with other 707 ROMs RUU_Schubert_hTC_Asia_WWE_1.57.707.02_Radio_5.52.09.16_22.33a.50.10_Signed_SCHUBERT_RELEASE fails with a update error 270: saying the ROM file is corrupt please help.

Unfortunately as a noob to the forums I can't post links. Add http to the above to make it into a link.
I had the same problem, but i managed to solve!!!
Invert the flash order from this thread: http://forum.xda-developers.com/showthread.php?t=1000520
Flash b2 (big one) first and ignore the error then flash b1 (small one) and the phone will boot
Now guys my phone is toast. It does not work beyond the bootloader mode. I tried flashing the device but the process gets stuck at 0%. I tried formatting the SD card but the same tricolor boot screen appears. What the hell has gone wrong? Anyone who can help me thanks a million. I would really appreciate it.
did you try flashing one of these 707 roms ?

if u stuck in bootloader mode, pull out the battery , and install it back again
It could be a faulty USB port during the flash process. Try another USB port.

Frankenstein htc one bootloop again :'( help!

So,
I've been around my phone for a couple months now, as you can see here (http://forum.xda-developers.com/sprint-htc-one/help/couple-issues-replacing-camera-mic-t2982125) i've replaced alot of parts and initially had a problem with bootloader stuck on bootloop. I followed the link the user, coal686 posted and it worked. But the new camera and bottom speaker were screwed so i had to replace them again, i got stuck again on a bootloop but the guide is not working anymore (for me). Could someone give me some help? What else can i do? i've tried to flash twrp and boot to recovery but it just boots again to the splash screen , turns off and boots again :\
edit:I gave it another try and now it worked, i disconnected the battery for a while.

Phone stuck at MI logo after trying to root the device

Hi all,
today i was trying to root my newly Xiaomi Mi8. (got it last thursday)
I used these steps to get it done: www . theandroidsoul.com / xiaomi-mi-8-root / (please remove the spaces)
after installing the magisk-v16.4 I have rebooted my phone. then I got stuck.
i have tried several things, and probably made it worse. i have wipe my whole phone all partitions. and via the TWRP recovery I have loaded the xiaomi.eu_multi_MI8_8.7.6_v10-8.1.zip rom.
after this installation I again got stuck on the loading screen of the MI logo.
I read somewhere that this can take some time, but it is on the logo for more then 3 hours now
can anybody help me pointing me in a new direction ? many thx !

Format in twrp (where you have to confirm with typing yes), transfer rom again, flash it. Boot, reboot to TWRP, flash magisk.
You are my HERO !! it works!
