Hi guys, i am very new to android device, I have a few questions about kernal and custom roms.

Lets say after i flashed cm9 into my phone, and I want to get back to stock ICS, how can I do that?

Is it using the recovery function provided that i have make a backup before or I have to flash the stock rom and kernel,which 1 has to be flashed first?
[Sony Xperia P, U, Sola, Go] K900:
You can restore a backup you made from recovery.

Hi friends...this is the first thread by me so far and that too bcoz i cant sort out my problem by myself.

so the problem is with my neoV's screen...first it started a few times while scrolling through lists...then anytime touching any option...the display showed vertical coloured lines starting from the top coming down and went blank in 1.5 seconds...then nothing...everything on the screen gives respond on touch but i cant see anything...just blank black screen.

at first the problem went away when locking the screen and unlocking after a minute...but now...it persists even after reboots...i cant even see the boot screen...nor the recovery options...so no way to do anything.

i changed kernels via fastboot, dried the device with hair drier...only repairing with pc companion or flashing stock ftf is left...but i think the problem is not software related.

i think i have damaged my screen by charging from a samsung charger.

i will update the findings after flashing a ftf or repairing with pc companion.

any of you have any idea about the problem?

thanks.
[Sony Ericsson Xperia Neo, Pro] Madfysh:
well, I think same as you, hardware problem, LCD passed away..

PCC or .ftf and to the service center.

btw, why you mean it's caused by samsung charger?
[Sony Ericsson Xperia Neo, Pro] unisol107:
bcoz the problem started after i used it for 3-4 days and bfore that nothing like that ever happened...my pet german shepherd chewed my original sony charger...so now i am using my brother's samsung wave2 charger and data cable.
[Sony Ericsson Xperia Neo, Pro] Madfysh:
coincidence I would say.. :)

Though my friend is having problem with one old slide samsung when charging it with SE charger, phone freeze, restart and lose sms's :) but that's not coincidence as it happens everytime when she charge it with SE charger... strange indeed.
[Sony Ericsson Xperia Neo, Pro] unisol107:
in my case...i cant authentically say it is bcoz of the samsung charger...anyway...downloading .431 ftf...very slow conection...then if the problem persists...i will have to relock the bootloader to take it for service.

but i fear they may ask for the charger...and if i take the torn charger to them...they will straight away refuse to repair under warranty...and buying a new charger will be costly...sony equipment is always costly...and i think it would be better to repair my charger by myself and replacing the display.
[Sony Ericsson Xperia Neo, Pro] Madfysh:
Don't worry, they wont ask you that. You are claiming warranty for phone, not charger ;)

In none of service center I've been to, charger was need to be given.
[Sony Ericsson Xperia Neo, Pro] unisol107:
Hi mate...my display is back to normal...i just dried it again with a hot blower...my guess might be right...it is probably due to moisture...now lets see how long it works...now i will get some dehessicators.

[Sony Ericsson Xperia Neo, Pro] Ysharief:
Thank God it came to normal. Btw You would have got new display and free service of your phone:D. If problem persists don't waist any time and go to service center,
[Sony Ericsson Xperia Neo, Pro] unisol107:
Unfortunately mate...it is dead again...now...service centre is the last option.

[Galaxy Tab Q&A, Help & Troubleshooting] asvantypography:
check development thread section,.
[Galaxy Tab Q&A, Help & Troubleshooting] salahmed:
Sure you can flash any rom as long as you select the proper one for you, if your tab is just p1000 that mean any GSM rom is compatible with it, p1000c mean cdma, there are also other variants like p1000l and p1000n.
[Nexus One Q&A, Help & Troubleshooting] diegolm:
Great work, your guide is amazing!!! I followeed it and ended with an infinite bootanimation :(, I'm trying to discover what I did wrong :fingers-crossed:, but the guide was superb! ;)
[Nexus One Q&A, Help & Troubleshooting] c2med:
I am sorry to hear that. Can you boot into recovery or is that broken as well? If you can boot into ext recovery try selecting "wipe/restore" → "wipe data/factory reset" and then try to install BCM again. I probably should have added that above, I will do that now.

If your recovery is broken but you can get into the bootloader (holding down trackball while starting up), you should be ok. You will probably need to flash Amon_Ra's Recovery using Hboot as was described in the guide from cyanogenmod link above. If there is a way to directly hboot flash 4ext recovery I don't know how to do it. Then you can try installing BCM again from the Amon_Ra's recovery and re-install 4ext after you get everything working.
[Nexus One Q&A, Help & Troubleshooting] diegolm:
I tried the Texasice ROM and it worked, but I didn't like it! Later I tried again BCM and It worked! I dont know, maybe I did something wrong... Anyway thanks again for the guide!!
[Nexus One Q&A, Help & Troubleshooting] intel415:
Does work the same if using fastboot method? Thx
[Nexus One Q&A, Help & Troubleshooting] c2med:
I am not sure which part you are referring to, but, yes, a few of the above instructions could be replaced with fastboot commands.
[Nexus One Q&A, Help & Troubleshooting] intel415:
The adb commands, instead using adb I can use fastboot commands right. That's what I used to root my n1 kinda familiar with fastboot. Thx
[Nexus One Q&A, Help & Troubleshooting] c2med:
I used the adb commands above because you can use adb to reboot directly into recovery (fastboot you can only reboot normally or into the bootloader) and you can also use adb to directly install apk files - fastboot cannot do those two things - it is more for flashing images (recovery, roms, etc). In order for adb to work make sure you have usb debugging enabled: go to "Settings" → "Applications" → "Development" → enable "USB debugging."

Note that adb commands are not required - you can reboot into recovery and install the 4ext manually.

It won't let me post a link right now, but just google "adb commands" to find a list of all the commands you can use.

Hope that helps.
[Nexus One Q&A, Help & Troubleshooting] intel415:
Thx. All I need it was to install black rose and partition it. Put zip on SD card wipe and flash. Installation was easier than I thought it would be lol

Also on ur guide you forgot to put 200 for the data part. You only had 220 and 16

Thx again got ics installed on my n1 smoother than cm 7.2
[Nexus One Q&A, Help & Troubleshooting] c2med:
Yeah, its not bad - glad you got it working! ICS has been smoother than cm 7.2 for me as well.

Blackrose didn't ask me about userdata - it just assumed that automatically after putting in 220 system and 16 cache... I'll make note of that in the guide so its clearer. Thanks.

Got the issue with not being able to get into recovery after step 4, but I don't have the recovery image to flash. Once the SD card was formatted in step 2 I don't have a download folder. I attached what is in my SD card right now. Help please.
[Nexus One Q&A, Help & Troubleshooting] c2med:
Look for "recovery.img"

Try to find if there is a "recovery.img" anywhere on your SD card, perhaps in the 4ext folder?

If you can't find it, do not worry, you can just go to the first page of this thread, click on the link labeled "follow this guide from Cyanogenmod" and then go to the section on how to download and install Amon_Ra's Recovery. Once you get Amon_Ra's recovery flashed you will be able to install any ROM of your choice.

You can reinstall the 4ext recovery later if you want.
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
OK I'm stuck on what the path name is suppose to be. I tried it every way I can think of. Can you take a look at my screen shot, and tell me where I'm going wrong? The recovery image is on my desktop, so I'm not sure what exactly I should be replacing "path" with. I tried it from the link, and how you have it in your note. You don't have the "/to/" after path as in the CM link.
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Well I tried a couple more times, and I can get it to seemingly do it, but it just hangs on this: (see screen shot) I get no error, and if I try to enter recovery on the phone I still get the reboot to the android and triangle with the ! in it.
[Nexus One Q&A, Help & Troubleshooting] n1newbie:
place the recovery under the folder which contains fastboot.exe and rename it to recovery.img

now use the command

fastboot flash recovery recovery.img from platform-tools directory
[Nexus One Q&A, Help & Troubleshooting] tommert38:
And right-click this folder while pressing the SHIFT key on your keyboard. Then choose "Open command window here".

WOW Thank you both. I spent literally hours yesterday trying to get it to work. Tried your suggestions, and in five minutes it was up and running!

---------- Post added at 12:31 PM ---------- Previous post was at 11:33 AM ----------

I may have spoke too soon. I followed the instructions to the end. Installed the ROM, and rebooted, but now after the X I get the Spazdog splash screen with the big Z in the middle and green dots moving, but it stays there forever. I waited 20 minutes one time. Tried reflashing, but I get the same thing.

---------- Post added at 01:17 PM ---------- Previous post was at 12:31 PM ----------

Just giving an update on progress (in case someone else is in my boat too) Flashed back to stock GB. Reinstalled recovery, and reflashed Spaz. Got past the X, and the splash screen, but now it's stuck on the Android logo that looks like the night rider beam that goes across the word. Been there now for about 10 minutes.
[Nexus One Q&A, Help & Troubleshooting] tommert38:
You do have Blackrose, right?
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Yep. Installed everything according to OP. I think it may be the partition sizes as I think flashing back to GB messed with them. It says 220 and 10, but after checking some threads, it looks like there is one missing (userdata). I tried flashing a custom GB from here http://xdaforums.com/showthread.php?t=1214543&page=98 and I was able to install everything. Got it up and running, so I'm going to start over for ICS, or do you think I can flash one of these for ICS http://xdaforums.com/showthread.php?t=1637166 , and then just flash the ROM after?
[Nexus One Q&A, Help & Troubleshooting] tommert38:
220/10 means that you have 220MB for system and 10MB for cache, everything that's left will be userdata, so it doesn't ask (total is ~436MB, so userdata will be ~206MB in that case).

In HBOOT you can check how large your partitions are, or you could use the FreeSpace app for example. Always make sure your system partition is large enough before flashing a ROM.
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Gotcha. Yeah I checked it, and that's what it says, so I have no idea why it's stuck on the boot. I tried it several times from scratch. I flashed the GB ROM, and it booted on the first try. Maybe a bad download. I'll try a new download to see. Thanks for your help.
[Nexus One Q&A, Help & Troubleshooting] n1newbie:
you can resize on ur own wid blackrose orelse you can use any of the custom made flashable hboot zips under the hboot thread.

remember to follow the instructions for that

famous nforuma

Hi all., thank you so much for this very helpful walkthrough

I followed all these instructions and I've got JB on my old Nexus One :)

However, when I go to Add Accounts there is no option for Google. So I can't setup my email/sync/play settings etc.

Did I miss a simple step?
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Yes you missed a simple step. You have to flash the Gapps that has Gmail, Play Store, etc. There should be a download link in the same thread you found the ROM in.
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
I did it! I think my issues were with the recovery. Since I couldn't get into 4EXT at first I had to do the recovery image which gave me CWM. No matter what I did I couldn't get any ICS ROM to work. I figured what the heck, and I formatted my SD card to start all over. Well since I already have BR I skipped that part. Now with 4EXT as my recovery I was able to flash ICS successfully. Thank you all for your help. I learned a lot.

PS to the OP - When you boot into HBOOT you say to press the power button to select your choices for the bootloader and recovery. This is incorrect. You need to press the trackball. Just thought I put that out there in case anyone else keeps pressing the power button thinking it's broke.

Nexus one bricked or not?

I have a Google nexus one for 3 months with the latest update 2.3.6 gingerbread .I must say that I was like that. Ie with the last update;*

************Subsequently, I had an encounter with the real extraornaire Jelly bean in a galaxys s3.In time, I jailbreacké of touch and i unlocked the iphone 2nd and 3rd generation. Of course I am not a geek either. It's just that when I have free time I enjoy flirting with mobiles.*

******

*But having a nexus one, smartphone old school but so advanced in terms of fluidity and beauty, and seeing the beauty of the jelly bean, I immediately began to leaf through tutorials to find a way to put this rom on my nexus.*

******* First, I was told about the benefits of root. I immediately followed a tutorial to do with blackrose.

***********Then a few days after I saw a tutorial that seemed to me the most in my reach to put JB in my nexus one. So I started. Here is the link to the tutorial: http://xdaforums.com/showthread.php?t=1804571.

*******In my memory after I think I have followed the steps of the tutorial to the letter so far or have to put the phone in bootlaoder to load the JB.

*******But now, the phone does not detect image to install. So I checked if I copied the rom jelly bean spazedog the root of the memory card, but it is there. And now, the phone can not start and going to recovery, there is the little android, the triangele and inside of exclamtion that appears. When I turn the phone simplment he hangs on the cross startup.

*****So the bootloader screen it says at the top:

If I understand you correctly it sounds like you are having problems getting into recovery? If that is the case see the note after step 4 in the original instructions and follow those steps to get recovery working. You should have a copy of 4ext's "recovery.img" if you followed the instructions in the first post. If you need help flashing a new recovery check out this link from cyanogenmod. Good luck.

This post helped me through to getting JB on my beloved Nexus One. Just like in the OP, I lost recovery after I resized using BR. I was able to reflash 4EXT and the rest was pretty straightforward.

JB is quite snappy and the experience is so heartening. I installed m2sd after that , i noticed that the total internal memory available was being displayed in negative numbers. It was saying free space as 170 MB though. Anything I can do to fix this?

Installation guide updated

I have updated the guide. Since the Spazedog roms have not been updated in a while and most people including myself are going to Evervolv I have updated the guide to reflect that, added some links such as where to get apps-to-sd scripts, changed some things to make the guide a little easier to follow, and made sure I emphasized the steps that can save you if anything goes wrong while you are trying to install a new rom. Hope it helps.
[Nexus One Q&A, Help & Troubleshooting] sphinxcs898:
Well, I thought I could use the APK, but then, i figured, the numbers show up correctly in the M2SD app and besides, the apps get installed correctly in my sd-ext partition, so no worries :)

Installed Google Now and playing with it. Feels pretty good that our 3 year old devices get JB ;)
[Nexus One Q&A, Help & Troubleshooting] pantsman28:
Hi everyone.

I have been following your guide and its probably the easiest to follow and understand for a newbie like my self.

Although, I am having problems with Step 5, believe it or not.

My Google Nexus One is now been rooted but having the mentioned problem regarding access 4EXT recovery. Which I need to sort!

My problem is I am not sure what file I need to select on Step 5. I have a number of zip files for JB but all of them fail during the progress.

*BlackRose - Made by Lecahe(dla5244) *

JB-260/10/166

Nexusone PUT ENG S-OFF

Hboot-7.35.5017 (PB9910000)

Microp-0b15

Touch Panel-Synt0103

Radio-5.08.00.04

The files I have tried to upload at this final are Evervolv-Acies-3.2.0-Nightly-2013.01.03-supersonic.zip, and Evervolv-Perdo-3.1.0p1-passion but the above link is hboot_jellybean_260-8-168.nb0

Am I missing a stage, ie flash hboot with the hboot_jellybean_260-8-168.nb0 ???

Could do with being pointed in the right direction!!
[Nexus One Q&A, Help & Troubleshooting] pantsman28:
Update....

I have 4ext recovery now working but having problems with installing JB

I have narrowed it down to needing to flash hboot with hboot_jellybean_260-8-168.nb0

as its not showing Should see “Jellybaby” on second line in fastboot menu...

could someone confirm?
[Nexus One Q&A, Help & Troubleshooting] c2med:
Make sure to install the correct zip for your phone

No you do not need to flash hboot_jellybean_260-8-168.nb0. Jellybaby is just the name that evervolv used for their pre-made partition scheme. It looks from your previous post like you have already used Blackrose on your own and named it, "JB", so that you now have a 260/10/166 showing in the bootloader? If so you do not need to flash the .nb0 file.

So you should be good to go as far as installing one of the zip files. Note that you attempted to install a rom that was for a HTC Evo 4G (Evervolv-Acies-3.2.0-Nightly-2013.01.03-supersonic.zip). Make sure you are installing a zip for your phone!

If you are going to use evervolv roms the Nexus One is code-named perdo-version#-passion. Since this apparently is your first jelly bean rom I would try one of the more stable ones like the evervolv Jelly Bean 4.1 final:

- Download here: http://dl.evervolv.com/static/r/Perdo/Evervolv-perdo-3.1.0final-passion.zip

- See full list of available stable releases here: http://dl.evervolv.com/release

Now that you have 4ext working make sure you "format all partitions except sdcard" and "wipe data/factory reset" before trying to install the zip you downloaded form the above links. Let us know how it goes... hope this is helpful. Remember you will need to flash google apps and likely some sort of apps2sd script as well. Enjoy.
[Nexus One Q&A, Help & Troubleshooting] pantsman28:
Thanks for your help....

I did manage to down the correct one from evervolv.com Evervolv-Perdo-3.2.0-Nightly-2013.01.05-passion.zip

and gapps-jb-20121212-signed. I must have been tired when I was downloading the new ROM

The main problem I have which I can't solve is getting A2sd to work or Mounts2SD (init.scrip on startup). I have formatted the sd to allow for ext2 partition. I have very limited space left on N1 but can't get the apps to run from card...

any ideas
[Nexus One Q&A, Help & Troubleshooting] c2med:
I would use a ext4 partition as indicated in my guide, but you do not have to do that. If you have installed Mounts2SD app you will need to follow the documentation in that thread to get it working. Have you set up the Mounts2SD app so that your apps, data, and cache are moved? Does 4ext recovery and M2SD see the ext partition that you made? I would make sure they are both seeing your ext partition first. If not, make an ext4 partition as instructed in my guide, make sure it is aligned correctly, and then try M2SD again. You could also try the other apps 2 sd script I mentioned - it will change your system info so that it looks like your internal data is your ext partition when you look in settings -> storage.

As mentioned in many other threads here, you have to give us a little more to work with than, "its not working..." ;)

Good luck.
[Nexus One Q&A, Help & Troubleshooting] pantsman28:
I followed the guide and have created an ext4 partition but have also created an ext2 partition for one of the others like m2sd. I am going to post in the M2SD thread to see if someone can help with the installation: I followed their guide but as mentioned I can't the init.d boot script is either missing or out of date??? the init.d startup script could not be copied to the system partition.... I am wondering if on this rom the init.d support is disabled?

Seems a shame I have got this far and can't complete the final stage....
[Nexus One Q&A, Help & Troubleshooting] c2med:
The ext4 partition is for m2sd or other apps2sd scripts to store your apps/data, that is its primary purpose.
[Nexus One Q&A, Help & Troubleshooting] sphinxcs898:
Here's how I installed m2sd:

Before flashing CM 10

a) I used 4EXT to create an EXT4 partition for 1 GB by following the instructions in this thread.

After flashing my ROM (4.1.2 Vijendrah's CM 10),

a) Downloaded the flashable zip from the m2sd thread: 5.1.4 EXT4 zip from Mediafire

b) Reboot into recovery and flash it.

c) That's it. The initial reboot will take some time for m2sd to prepare itself. Reboot once more after you're done

d) Check the m2sd app to see if your EXT4 partition is created successfully.

Note: I would recommend doing this before you install any apps. First time I did this, I had a ton of apps and I ended up in a perpetual boot loop for like forever.

Also, having a faster SD card helps too. (Preferably Class 10)

I hope this helps.
[Nexus One Q&A, Help & Troubleshooting] pantsman28:
Hi thanks for the info and the ROM suggestion. I have flashed the rom and it works great.... I did however Blackrose the phone again to 270/10/156 just incase I didn't like the new rom. Everything works great but still can't get m2sd to more apps to sd! M2sd is installed and running and have check the reformat of the SD it does have EXT4.

Does m2sd only use the sd once the internal is full? for some reason I was expecting the internal storage to display 1gb which is what I set it to?
