Evening all,
I have been advised to post here on XDA from Android Forums. This is a copy of my initial post on there to explain the background to my issue.....
Hi there,
I have HTC Desire from O2 and after 12 hours of online searching and tweaking I'm hoping someone may be able to help.
I received the OTA upgrade yesterday which I accepted because I thought O2 might have it sorted by now. Obviously not. Anyway update ran with no interruption but then rebooted to a frozen O2 screen.
I searched the net and eventually found the guide to update the phone using the RUU Rom. I followed this to the letter and the installer for the RUU wouldnt't open. I then realised that Google Chrome hadn't fully downloaded the file (113mb not 171mb). I then used a download manager to ensure I had the full file. It then ran and seemed to be working... until 80% in when I get ERROR 110 File Open.... please use a complete RUU. I downloaded it several more times in various ways but still same result. By this point my phone was pretty much bricked.
I had black screen with silver HTC logo in the middle and 4 exclamation marks in the corners.... this remained whilst the phone was plugged in and the buttons in any combination did nothing. When i removed the USB cable i got a white boot screen with RUU highlighted in orange and again.... buttons do nothing. Every time I ran the RUU file it brought up a green bar as if it was making progress but then errors at the same point every time. (Error 110 use complete RUU... file seems to be complete now at 171mb)
I tried it on two computers, one win7 and the other vista. The vista machine doesn't even see the phone, it gives a USB error before the update begins.
At 2am I used the SDK download and typed the following at command prompt.... "fastboot oem boot".... phone instantly boots into O2 Froyo and works fine. If i then unplug the phone, turn it off and on again.... i get the black HTC screen again, back to square one.
At the moment I have fastbooted it so its working and have used the goldcard tool to obtain the CID and created the .img file.
I don't know what to do from here!!.... the update obviously hasn't FULLY worked but it must have completed enough for the thing to fastboot and seems to have full functionality (calls, wireless, network etc)
I don't really want to void the warranty but O2's only option is to send it off for 14 days to have an engineer tell me its buggered and send a replacement.
Any advice is appreciated.
Rich.
A couple of helpful guys on there have tried to advise me but without success. They suggested rooting etc but here is my problem.....
At the moment the phone seems to be working fine with Froyo... but the only way I can get my phone to start up is by plugging in and running "fastboot oem boot" from command prompt. If my phone is powered off and I turn it on in the normal way, I get the black screen with silver 'HTC' and triangles in 4 corners and all buttons do nothing!
I have tried fastboot command whilst holding down the volume keys etc and it just boots normally. Obviously something isn't right and I can't let my battery run down otherwise its useless until I can fastboot it again.
So this is preventing me from accessing any of the menu's required in the flash/root tutorials.
Can anyone help or do I just need to ensure I don't run the battery down?!?
Thanks in advance
Rich
if you have a goldcard already, have you tried flashing a diffrent ruu from fastboot? maybe just a generic htc one rather than the o2 one?
Hi,
Thanks for your reply.
Could you advise me which RUU would be the best to use?
I have looked through the list on shipped-roms website but apart from the obvious O2 ones, I don't understand which ones are which!
Thanks
Rich
Hi Rich,
I have exactly the same problem. Have you got any feedback about whether you have solved this issue?
Thanks!
Kelk
Edit:
I think I may have got it sorted. Downgrade to 2.1 as per:

Hi there,
I haven't solved my issue yet. At the moment I am using my phone on 2.2 but trying not let the battery run flat (I have to use fastboot from command prompt to get my phone to boot up)
Did the tutorial above work for you?
My issue is getting a working goldcard. I'm not sure whether mine has worked succesfully because when i've tried running the RUU of either the unbranded froyo update or even the O2 original, i get and error message and it doesn't work.
I followed the goldcard creation tutorial but I still get the CID error when trying to run the various RUU files.
I hope I can sort this soon because i've been close to throwing my phone out of the window several times!!
Cheers
Rich
Hi Rich,
Yes, the above tutorial worked for me. I think this is because it downgrades to a former version of HBOOT.

Use Goldcard + your shipped o2 ROM (ROM that came originally with ur phone 1st time). you can get the rom from HTC official website. enter your Serial Number t download (i recommend using Mozilla built in download manager, coz Google Chrome always give me Corrupted Download when downloading Large files)
Hi, think I know a bit of what I'm doing, read all I could, etc.
W7 laptop, SD SD with HP format, RHOD100.
(Can get serial # from Nexus 7 with ADB install, can reflash WM from SD, etc)
USB cable to computer.
I can 'flash' (update image) new Android RHODIMG.NBH to phone, I get filled progress bar, and then Update Complete, UPDATE SUCCESS and phone will not cut off (stuck in bootloader?) I do manual reset button.
Then I can 3 finger reset (SEND, END, + ON) to get tri-color, and then VolUp option. (So far, this is just like WM reflash) I push VolUp.
Screen goes to "Restore... Waiting for completed" and unfilled progress bar - and that's it. At this point, other resets can get me tricolor with USB, white HTC with NO radio, version, etc, and this waiting screen.
(I can use same process and get right back to WM.)
Where is my error?
THANKS!!
You can't flash Android with USB. SD is the only way to flash the NBH for Android.
Do you see the blue boot loader screen?
(I've also got the image for android on SD, just not getting there...)
I never get a completely blue screen (get tri-color), I go exactly as far as I mentioned - 2nd progress bar with no progress.
Using these instructions and downloaded files... http://forum.xda-developers.com/showthread.php?t=1566955 stuck at step 10 or 11 or so.

Did you unlock your phone?
Unlocked long ago, olinex or something similar. Been trying various roms for years with no problems, played with SD android for awhile, wanted to try NAND.
I have good SDK, etc, put image on SD, phone finds it, first loading bar looks great, reboot, second loading bar never starts.
Do you guys never see 2nd progress bar ("Restore... Waiting for completed") - is my fault before that? Is there a better set of instructions that what I'm using?

So you flash the NBH... and it's never flashed successfully? Not sure what you mean by "second progress bar"... there's only one when you flash the NBH via SD.
OK - now we're talking!
I definitely see a second progress bar that never starts under "restore, waiting for completed" on a whitish screen as above.
Is the RHODIMG.NBH from that instruction set the correct one?
I will try downloading again and moving to SD again in case of file fault.
THX for helping...

I guess I'm still not following.
Have you ever flashed via SD? The process is really quite simple. Just place the RHODIMG.nbh file at the root of the SD, and put the phone in bootloader mode. It should pickup the file and offer to start the flash.
Yes, and since I tried this I have also successfully flashed back to WM by SD, numerous times now.
I am not successful at flashing and then loading the small .nbh for Android
Am trying new download now...

So to get things straight, you downloaded this file and put it on the SD. Now when you load it, you won't be able to get it to load using the recovery. Recovery is for Windows original files only as far as I get that.
Instead you just press and hold the volume down button while powering on the device. After you see the tri-coloured screen you can let go. You will get prompted with a white screen. On this you'll see:
Now the rhodimg.nbh is detected and by pressing the power button you can flash it. (or press volume down to cancel and return to the tri-coloured screen) After it said OK/Succesfull you remove the battery or press the reset button, after this there's no further steps, you just let it power on and you get a BLUE screen with some white texts called the LK bootloader / minipooploader by [ACL]
Here's a short instruction video to explain what I typed.
Al - THX for joining in!
That's the file (only one I can find), I do exactly as described, but at "battery or press reset" I get a white HTC (like would have 4 files listed on WM) that cuts off after 4 seconds, a three button push gets me a reload with no progress.
I made films...
files on SD - http://www.youtube.com/watch?v=ZbK8aWh9378&feature=youtu.be
process - http://www.youtube.com/watch?v=01Uq1dqtydE&feature=youtu.be
that show reset and 3 button reset (USB in here, same USB out) (Also, fresh solo Task 29 from RUU advanced...)
Any clues anyone?
(Could RHODIMG.NHB be bad on server?)
Not sure why you are doing a hard reset after you load the android NBH. Skip that.
Just let it load.
The instructions and post 11 above indicate reset.
I'm trying just leaving it at the Update Complete UPDATE SUCCESS progress bar now....
Nope - that just sits there after RHODIMG.nbh - OK, OS - , and UC/US,...

Just a regular reset, not a hard reset is what I think they are meaning. I have lost count of the number of times I have loaded android onto my device, and I have never ever done a hard reset after the initial nbh load.
When I load android on my rhod400 it always hangs at the update success screen from the initial nbh load. Try just popping out the battery (and putting it back in) and letting it boot normally after you see the update success screen from the android nbh. You should get to a blue boot loader screen.
That (simple on or reset button) after android.nbh success gets me:
a white screen with HTC (that would normally [WM] fill in with b,r,s,something - 4 ?file versions) for 4-6 seconds, and then off and blank. Battery yellow will cycle 80% on. Subsequent on times out (HTC white) and off as above.
Have you loaded recently with the current file?

Unless you're using some old file, yes I have flashed recently. Just flashed a TP2 the other day...

That's where you're getting all your NAND downloads from yes? Please ensure you have the newest stuff. This part is really the "easy" part. Just need to be SPL unlocked, then flash .nbh via SD. Seriously, that's the easy part... the hard part is getting your computer to recognize the phone in fastboot mode, and flash the recovery image - that's the step I always seem to have issues with.
This is an video from a Rhod 210, but it gives you a good idea what to expect. Useful info starts around 7:00.
http://www.youtube.com/watch?v=_qNCHqGPofI
Redid it all - exactly per video... fresh downloads. etc...
Where video shows carrier splash, then 4 circular buttons, and then blue with text, I get white HTC for 5-6 seconds and then off.
Just to be sure, since original thread evolved...
Mine is a RHOD100, SEA Roms work fine, SPL 0.85 olinex (AT&T freqs, they think it's a Tilt 2)
Seems it was only some phones early...

Hey all, this is my first post on this forum. I registered just to let my voice be heard.
Let me just say that I have done extensive research into these problems but I don't want to brick my phone so I want to know the direct steps for me.
OK my problems are:
Upon turning on the phone the original Motorola logo is gone and is instead replaced by:
"Unlocked. PwrReason: PWR_KEY_PRESS. OS will boot in 5 seconds. Press a key to stop countdown. Avaliable Modes are: " and lists 14 different modes I can choose
This happened after I accidentally deleted my pds folder or something of the sort. I must've partitioned something accidentally and as a result my phone did not boot the next time around. It booted after I did a battery pull but gave me the next problem.
Upon booting into CM10.1 I noticed that the soft keys would not work. The entire screen was recognized as one big touch surface.
I deduced that some file was deleted which makes the screen recognize the soft keys, so I proceeded to do some research into it. The methods I saw to do were doing some sort of pdsfix which is not recommended unless necessary, which in my case is very necessary. I can boot into Romracer's recovery (5.0.2.7 I believe it is) as well as my OS. Everything is working except for those problems I listed. I am not sure if my phone can boot into fastboot but I can try. Please post your answers because I really need to get my phone working perfectly again. At this point, it is only useful for texting and a little music (and settings). I can't go into much else without restarting the phone each time (you must know why).
EDIT 15/04/13
-----------------------------------------------------------
I just flashed pdsfix(gingerbread).zip and I am now able to use my phone at normal speeds and even overclock if necessary. I was running epinter's CM10.1 Rom
Fixed half the problem!
Okay so after many hours of trying, I managed to install the drivers for fastboot on my computer and did the fix for the pds file.
First I downloaded moto-fastboot.zip and extracted to my C:/ drive.
Then I tested if my device was recognized. It didn't recognize it at all, so I went into device manager.
In device manager there was my problem. I saw fastboot with a yellow exclamation sign. I right-clicked it and directed it to where I had previously downloaded fastboot drivers. (Found them here: FASTBOOT DRIVERS
It installed nicely and when I tried the commands listed in Method 2 on this page PDS Partition Fix it worked perfectly!
So I proceeded to restart the phone, no issues. But the Motorola logo at the very beginning is still not there. It says unlocked at the top left and displays the same options as before. The phone is still fully functional without it, but I want to get it back. I will be doing more to fix this though.
But the best part is that, my soft-keys are working perfectly! :laugh: I do notice a little lag in the system but that will be fixed soon. Hope this helped anyone who didn't know what to do.
P.S. If you find a way to restore the Motorola logo on boot, please tell me!

Perfect! Thanks much for finding that for me. I now have the problems fixed except that my cpu won't clock above 608 mhz even when I put the min clock slider higher than that value.
I suspect that perhaps I flashed the froyo pdsfix instead of gingerbread. Maybe that is causing the problem. I'll try and post my results soon.
My Atrix 4g is fixed!!
Wow I can't believe I finally fixed it! It was as I suspected. After downloading the pdsfix(gingerbread).zip I rebooted my phone into fastboot and proceeded to flash the zip. And who would've guessed it? I am now able to clock at usual speeds including the 1000MHz of old ^_^. I am sooo glad I found this forum. If anyone had similar problems you can try the steps I did.
P.S. For the record I was running epinter's CM10.1 Rom for the Atrix 4g. I may go to Neutrino's in the near future, but I am just glad to have my phone back in working order :laugh::laugh:
Before the incident, I had root, no unlocked bootloader, stock JB, v20h.
What had happened was I was trying the Font Installer app in th Play Store because of the added customization that would have been nice.
I found a cool font, and I backed up my current fonts and then pressed install. SuperSU asked for permissions like normal and then my phone restarted.
Then it was so that my phone was stuck at the T-Mobile boot animation after the LG Logo. For about 15 minutes. This is where I believed something was starting to go very wrong. After contemplating for a few extra minutes, I decided to just take out the battery and restart. Same outcome. I thought of all the things that were on the phone thus far because I had just gotten it recently, and decided that it wouldn't hurt me to just do a hard reset by pressing home + vol down + power. Everything went smoothly. Except for the fact that even after I did that, it was leaving me at the T-Mobile screen.
I decided to look on the forums for development and tried to do the unbrick method, to no avail after about 3 hours now. I used the LG User Support Tool and since I hadn't updated to V20f, I decided to do that to see if it would solve my problem. It still didn't, and I'll be honest, I'm a little upset just typing this right now.
I also tried the Upgrade Recovery option and it warmed my heart to see that the process was actually starting. But right at the screen where it says that it is supposed to be downloading something, it freezes up and nothing happens no matter how long I wait. I saw somewhere that it should be a glowing red bar, but I do not see that anywhere, it is just frozen, saying Time Elapsed: 00:12. And before anyone asks, yes, I ran absolutely everything as an administrator.
Is there any possible way to bring this phone back? Any help would be immensely appreciated. Thank you in advanced.

did you hard reset? then turn off your phone disconnect the battery, connect to the pc holding the volume up button? then try the Update Recovery?
i would just go through that process over and over until it works, theres not really a way to brick this phone i've heard...

Thank you for your reply! I have tried hard resetting multiple times, but I had removed some bloatware apps (I will quarantine them next time instead because I don't wanna go through this ever again) and I have tried the kdz method to only be stuck at 15% every time when I followed instructions to the pixel. I have tried to do it on windows 7 and windows 8. I have also tried the fastboot method by lelus, and that manages to "work" but I am still stuck at the tmobile boot screen afterwards. I have gotten the hang of the process of getting into the fastboot, but what do I do from there? I chose to flash ics xloader and uboot, but the process goes by so fast, I'm not even sure it is doing anything. The LG Tool has really gotten me nowhere, it just gives me a lovely error and then cannot continue the upgrade recovery process.
It said somewhere that after I flash through the fastboot I then have to try the kdz method, so I am going to do that now and see if it works. I don't know if there would be a difference between flashing a jb kdz or an ics kdz, but I will just do ics to be on the safe side.
I am quite happy to say that flashing the ics kdz was successful, and my phone is now up and running.
My p769BK is stuck on the LG screen. /: months
Sent from my LG-MS770 using xda app-developers app
im terrible with fastboot, i used the unlock the bootloader for noobs with an offline flash.
heres what i did to get out of bootloops....
alright, this is all from memory but the offline flash didnt work as well for me when stuck in weird bootloops.
Step one-going back to online flash---->
A---
the easiest way i found was to go to C:/windows/system32/drivers/ect/hosts
right click>open with notepad
there should be two lines at the bottom
"127.0.0.1 csmg.lgmobile.com
127.0.0.1 csmgdl.lgmobile.com"
i would cut them out and paste them in a text doc in the same folder for reference later...
but either way you should remove them from the hosts file and save
B----
Make sure your small server is closed! once you minimize it it should go down to your status bar (shttps)
Step two-LGMS---->
make sure you have LG mobile support installed or install it.
open lg mobile support
install needed drivers for your phone
power your phone off/remove the battery
put battery back in
connect it to your computer holding down the volume up button
S/W UPDATE mode should pop up, if it doesn't preform and hardreset and try again til it works (it will)
then in the top right corner there should be a button or two click them both until you see
"restore update" or Update restore or something to that effect
select that
and let it ride man
i got my phone ****ed many times and just had to keep redoing this until it worked. if your bootloader is truely unlocked you can probably go through all that again and get CM10 working, i did but im still working through kinks.....
GOOD LUCK feel free to ask any more Q's about this process if you run into any problems
Rooted Fire hd 7 screen repeatedly turns black
Hey guys, so I had just rooted my fire hd7 and then I tried getting the google apps on it. In the process, I installed some google apps and then my fire hd started going to a black screen( I do believe I followed the instructions wrong ). As soon as I unlock my device, it shows the home page for a sec then the screen turns black and it repeats that process. I tried the factory resets and reboot and it did not work.
I hope I did not permanently damage my device. Is there anyway to fix it from my computer?

Does it do this after a reboot? Do you have ADB authorized?
How did you exactly try to install GAPPS, with JMZ tool ?
Potentially it's simple to disable various apps via ADB, if you are set up to do so (a great tool is "Debloater")

Hey im not sure why my title says goes black after "flashing gaps" i have no idea what that means lol
I didn't write the "flashing gaps" part. But what happens is that everytime i turn it on and slide left to unlock, it shows the "homepage" for about a second and turns black , and it repeats that process until i turn it off.
Yeah im sure there is some way to fix it through ADB but i have no idea how .
I had download 5 google apps, but I installed them wrong. i was in the Es File program trying to install one and it went wrong after that.
any videos on how to use "Debloater" and where to download it from.? I will definitely check that out. I just had this tablet for a month I would highly appreciate it if someone could help me fix it.
