To avoid black screen after double vibration, you might want to change panel. Panel 1 works the best for me. However I have read somewhere in this forum, not every TC works with panel 1. Try with haret first and start playing with default.txt changing panel_type value. I finally can use any newer kernel with haret. Btw, you can also check your dmesg for any [error] messages.

PS: I am using pola100 with haret, zimage 02-07-10

installing the system

If don't want to create them you can use nand or image disk
[Touch Cruise Android Development] sagytb:
OK, I have 1 GB card, I will create partition.

Do I need a specific partition ? I mean I will split the card to 2 different partitions 800\200 mega each.

Another question, where should I put andboot directory ? for example I will move andboot directory to the 800 mega partition and just leave the 200 partition empty ? correct ?

Should I format both partition as FAT32 ?

[Nexus One Q&A, Help & Troubleshooting] Jep4444:
Every once in awhile I'll turn my screen on and the screen won't respond to touch, if I hit the power button it only toggles the backlight, not the actual display. If I let the screen time out, it'll still toggle the backlight but the screen won't turn on. This usually resolves itself after a minute or so but it's becoming increasingly frustrating.

Also the problem did appear once or twice when I was on EPE54B but it's become significantly more common(like 3 or 4 times a day) since upgrading FRF91, I can't recall if it happened on FRF85B and it has yet to happen when I'm already using the phone, only when inactive.

PS the wifi seems to lose its connection when this happens although I've had the issue when not connected to wifi.

My phone is not rooted nor is the bootloader unlocked.

I can think of 3 possible steps to try out.

1. Check your Backlight settings.

2. Soft reset. Maybe it's just a temporary glitch.

3. Hard reset. Maybe something in the registry went corrupted.

I hope one of these can solve your problem.

Short and sweet:

1. I'm using the recovery that comes with Toast's 2of2 method (this is Amon Ra?) The Nand/ext backup fails for me and I read in a thread that's expected, but I can't find it again with the forum search. How would I fix this, and is it necessary? Is the regular Nandroid backup good enough?

2. Does a Nandroid backup include the kernel? If I push a custom kernel and have problems, will a Nand restore revert me to the kernel I had when I made the backup?

Thanks for the help in advance.

[EVO 4G Q&A, Help & Troubleshooting] trentlythp:
1. Do you have an EXT partition on your card? If not then you can just use the straight Nandroid backup.

2. Yes a Nandroid should back up the kernel at the point you made the back up. (not 100% sure but 99% :) )
[EVO 4G Q&A, Help & Troubleshooting] omegasun18:
I hate to hijack the thread but it looks looks like it died down a little and in my search effort this is the closest to what my question is. so to save making a new post on something probably answered before.

I am a relative noob. (i know sad) but i am learnign fast. I was wondering what exactly a nandroid back up does and does not back up.

I am doing the Starting over method to get back to stock 1.47(rooted) to see if it fixes 4g and think i can just nandroid after doing the method described to get my rom back etc. My only fear is that by nandrioding what ever benefit i got from starting over will be reverted.

Srry for the long explaination but basically if i Nandroid is it basically a complete image changing literally everything back to the previous state(ala HDD img)? If not will doing the starting over method then nandroiding revert me back to having the problem again?

Thanks in advance.
[EVO 4G Q&A, Help & Troubleshooting] dglowe343:
Nandroid backs up your entire system config. Radio, software, kernel, rom, etc. As long as you don't unroot, your system will be exactly the way it was after you restore.

Omega, if you do the back to stock root and then restore Nandroid, I'm pretty sure it will be as if you never did the back to stock. Pretty sure but not 100% positive.
[EVO 4G Q&A, Help & Troubleshooting] nebenezer:
Nandroid does NOT back up or restore your radio, wimax, boot or recovery partitions

AFAIK nand only backs up your system and userdata partitions, not positive about the cache or misc partitions.
[EVO 4G Q&A, Help & Troubleshooting] omegasun18:
Thank you very much. This should mean that once i do the starting over i should then be able to just nandroid back to my rom without having to redo my kernal/theme/rom and it shouldn't mess up my wimax radio again.
[EVO 4G Q&A, Help & Troubleshooting] nebenezer:
Correct :).

*edit- looks like I'm wrong about the boot partition. I just unzipped a nand and there's a boot.img in there.. still shouldn't affect radio or wimax though
[Galaxy S I9000 Q&A, Help & Troubleshooting] dakine:
I can't seem to find a straight answer to this so I'm starting a new thread.

With the JF3 firmware the GPS on my 2 phones is often not very accurate or completely loses it's position under what could be considered good conditions for a gps reciever.

Did the new firmware fix this problem?

Please only reply if you actually noticed the problem and can compare it with the new firmware.

Using GPS test is the phone now able to use signals with an snr of lower than 22?
[Galaxy S I9000 Q&A, Help & Troubleshooting] Elinsa:
No, it refuses to use GPS with snr under 22, as long as you don't locked them when they were higher. In that case it keeps them downto snr 17, and then drops them.
[Galaxy S I9000 Q&A, Help & Troubleshooting] peterlan:

Mine also locks in a few seconds, but it loses the lock again after a while. Then it locks again, the lock disappear, and so on. Completely useless as navigator.
[Galaxy S I9000 Q&A, Help & Troubleshooting] sjdean:
This is quite worrying, because it suggests more than just a firmware problem.

To those who have flashed and it hasn't worked, some suggest flashing using the repartition option.

But this experience is why I don't want to flash my phone. If there's a hardware error, I can't rightly be taking it back.

Might get a HTC Desire and put the extra few quid up towards a 32 Gig memory card.

[Galaxy S I9000 Q&A, Help & Troubleshooting] crabby09:
on further testing... My phone does use satellites of 19 to 22... But only if it is connected to less than 8 other satellites.

And I don't seem to have a disconnect issue.

Crabby
[Galaxy S I9000 Q&A, Help & Troubleshooting] dakine:
Yes the problem isnt that it wont connect but that the thing often thinks you are on an offramp or a road next to the highway you are travelling on because the sinal is too weak/inaccurate. I tested this with 3 different nav programs and get the same result.
[Galaxy S I9000 Q&A, Help & Troubleshooting] sjdean:
Let me get this straight, using GPS Test, you do see orange satellites through regular use?

This is all beginning to make sense now.

Unlike HTC which seems to use a GPS chip that is capable of 12 Satellite fixes, Samsung is using a GPS chip that can only lock onto 8.

I would think therefore that what it is trying to do, is to select the 8 strongest satellite signals which means it's already at a disadvantage, because as soon as you walk behind a tall building, it has to work to try and find and lock onto others. But when you walk past the building it goes back to the other satellites.

This probably explains why everything is jumping around. Because it's not using the weaker satellites in the distance until its too late.
[Galaxy S I9000 Q&A, Help & Troubleshooting] bl4ckdr4g00n:
Maybe you guys have the problem of "you hold it wrong" :D

when I put the phone's face upward, I got only 2-3 satelline locked

No need. Just enable Skyhook mode in GPS tech menu.
[Galaxy S I9000 Q&A, Help & Troubleshooting] veper:
What I find really interesting is that Skyhook mode is supposed to assist GPS using WiFi: [Google "SkyhookWireless How It Works"] (sorry, no links allowed for newly registered users ;)

In practice, I have my wifi turned off (not even set up), and GPS works like it should. Does that mean that Samsung messed the code up and enabling Skyhook mode activates some other (essential) function within the code?

Awsome !!!! Thisted totally work.. Super sweet.. Prolly going to use more bat..
[Galaxy S I9000 Q&A, Help & Troubleshooting] Seifer1975:
Hmmm, enabling skyhook made it worse for me. While it will log on to satellites with signal strength <22 with it enabled, it is very unstable and accuracy never goes below 200. When I turned it off, it locked on to fewer satellites but accuracy never goes above 100
[Galaxy S I9000 Q&A, Help & Troubleshooting] veper:
Which firmware do you use? I have XXJG3 (pda) and XXJG1 (phone and csc) installed. Without Skyhook, I receive up to 8 satellites with SNR between 15 and 40, but GPS cannot get stable lock. With just Skyhook enabled (tested without SIM card + disabled and unconfigured WIFI) I get about the same number of satellites, SNR is 5-10dB better and most importantly, I *never* lose lock =)

I still don't understand why enabling Skyhook 'fixes' the problem, as Skyhook by design should assist GPS using cellular and/or wireless network. Like mentioned already, it looks like Skyhook mode doesn't exacly do what it is supposed to, but rather enables some part of the GPS (micro?)code that should be enabled by default.
[Galaxy S I9000 Q&A, Help & Troubleshooting] peterlan:

[Galaxy S I9000 Q&A, Help & Troubleshooting] Seifer1975:
With skyhook, it logged on to a satellite with strength 17 (orange). It never does without skyhook. But with it, the accuracy is really poor
[Galaxy S I9000 Q&A, Help & Troubleshooting] veper:
I have an opposite situation. With Skyhook (or without) it won't lock to a satellite with strength less than 22 or so using XXJG3. Skyhook just made it keep a tight lock.

Using stock XXJF3 it occasionally locked to satellites with less than 22 SNR.

For me the GPS is far better with JG1.

Before I flashed I wasn't able to use Sportypal and many other simular programs at all. The program would not give me any information about trackings whatsoever. Google maps was quite inaccurate (often 100m radius but kept changing).

With JG1 the Sportypal app is possible to use. My first impression is that it's quite below the quality I had with my HD2 but at least it's working. I drove a couple of km on the road with my car and the line was as could as a GPS should be. I'll do a couple of more tests.

The google maps position also is more accurate.
