[Q] USB connection issue

I've searched high and low, and I can't find any existing threads that really address this issue.
My captivate is rooted, running Cog 2.3b8.
This week I connected my phone to my computer to charge overnight, just like I do every night. The next day the phone was dead, and with some extensive investigation I determined that for some reason it didn't get a good connection and ran the battery down.
It seems that the stock USB cable now won't get a good connection at all. It will charge if I fiddle with how it fits, and hold my mouth just right, but it won't make a good data connection. Occasionally it will make a data connection, but my computer won't recognize the device and my phone won't give me notification that it's connected.
I normally have the phone set on debugging and set to select connection, but I've tried every option. I had Kies installed originally, but I hadn't used it for some time and uninstalled it to make sure that wasn't the issue. I also deleted my drivers and downloaded and installed them again, multiple times. Finally, I've used 3 different data cables, and all of them get a good charge connection, but don't register on the computer or on the phone as data connections.
The phone hasn't had any previous issues with the USB, and unless my kids did something to it, wasn't dropped or damaged while attached to the USB or otherwise.
Additionally, I don't believe there has been any liquid damage to the phone. The liquid indicator patch behind the battery is white. I did notice that my car charger cable had some very minor corrosion on it, which I suspect is getting some minor water on it from briefly being dropped into my floor mat. It was connected to the phone while it had that corrosion on it, but I do not know if it was actually connected while it was wet as I didn't note it until after the fact. I carefully cleaned all of my cables and the phone connector without any changes.
While I could deal with syncing various things via wifi or bluetooth (though I suck at building networks for wifi networking), and I can make the phone charge in a number of various ways, but I'd like to flash to the new Cog and/or go to the stock Froyo if/when it actually arrives, and I'm not sure how to go about doing that without the USB connection for the Odin master clear and reset to stock. Can I use the build in data wipe, use bluetooth/usb/wifi the update.zip and kick it into download mode in a different way? That would get me back to stock, but I'm not sure how to root back to stock to use ROM manager or titanium back up without the USB.
Any suggestions? Is there something special or proprietary about the Sumsung USB that makes the connection that my aftermarket, data capable, USB doesn't have so it won't work for my phone?
Also, is it possible that it could be related to a bad ROM install? This is my 3rd version of Cog, and I trust DG's work pretty well, but I have a LOT of issues with apps crashing that I didn't have on previous versions, and have pretty constant vibration notifications for something without any indication on what it's for. I won't say for certain I didn't screw it up, particularly with the master clear in Odin.

I occasionally see issues with usb on my windows laptop. Reboot, try a different cable, different port, etc.

I've tried 2 different computers and 4 different cables, and have done reboots on both the phone and the computers along the way.
I think at this point the answer is either A) my samsung cable is bad and the other cables I used are no-data/charge only even though they were sold as data or B) I damaged the usb port on my phone with either the corrosion or some manner of trauma that I'm not aware happened.
I've contacted Samsung to see what a repair will cost, since I've read threads (here I think) that a motherboard repair was only $70 outside of warranty as a result of liquid damage, and a buddy of mine has an Epic on Sprint and I'm going to try to borrow his Samsung branded cable to see if I have the same result with it as I do with mine.
If I am SOL with my usb port, is there a good way to wipe, flash, and/or root without it? I can transfer files in via bluetooth or wireless, and I backed up with Titanium Pro into my Dropbox. I know I can flash new with ROM manager. I suppose that means I can concievably push a new ROM zip on with blue tooth, go to downlaod with ROM manager. Is there a good way to clear/clean everything like Odin's master clear without a USB? Is the one built into the phone sufficient for that? Is there an APP or sorts that will do it?
I honestly don't mind sending my rooted phone with a custom rom to Samsung if I *have* to, I purchased it used and don't have a warranty to void anyway, but I'd rather not send it full of all of my personal data, and if I'm going to wipe it, I might as well do everything else.
And honestly, I can charge via the usb without a problem, I put all my music in my external SD, which I can remove and write to outside the phone, and I can put ROMs on via the bluetooth, so I can *live* without doing data via the USB if I *have* to. Heck, I'm planning on getting an Atrix when they come out for my wife, and I can always clean it off, go to stock, and give it to my wife and play ROM of the day on the Atrix.

Honestly, there is no need to flash stock unless you really mess something up. Obviously the risk is greater with no ability to use odin but the choice is yours.
I have seen the stock jh7 in a flashable zip here somewhere.
edit....here is the thread: http://forum.xda-developers.com/showthread.php?t=790080
edit again....the code for the dialer to wipe your phone is *2767*3855# though i really don't see the need to use it unless you are sending the phone in to warranty

I don't get it. I just don't get it.
I'm now at a loss for words. I took a fine grit sandpaper and meticulously cleaned the usb on the phone, blew it out with compressed air, plugged it in and it worked instantly. I unplugged it, plugged it back in, and again it worked. I tried it with a different cable, and different plugs, all success. I was thrilled. I sat the phone down, and a smile on my face, and went to do some other things around the house. I figured I'd let it charge, come back, and do my ROM swaps with a full charge.
And when I came back, the plug had slipped out of the phone again, and it hasn't connected since.
So, either it needs cleaned again and all the cables I've plugged in are causing the issue again OR it's something to do with it coming out of the phone w/o disconnecting the usb in windows. I've been in "ask me" and debugging each time, and didn't mount the phone.
I'm exceedingly frustrated with this right now. Samsung won't respond to my requests, I can't figure it out, and I'm about 10 seconds from smashing the @#[email protected] with a hammer and going back to my 10 year old flip phone. In fact, I actually considered buying a $50 iphone 3gs for a moment.

[Q] Captivate Won't Charge But Will Recognize PC Connection

Edit: It looks like this is a hardware issue and I'll likely try to get it replaced via insurance since I cannot revert to stock using Odin. It is impossible to revert without using Odin right? Thanks to all who read!
To start, I just want to state that I've searched and searched for answers/information on this (not just on XDA forums either) and I haven't found a similar issue - my sincere apologies if I missed it.
Quick "this post is way too long to read" Summary:
1. Phone will not charge
2. Phone will recognize PC connection via USB but with no functionality
3. PC will not recognize phone
4. All details on what I've done so far below
Friday 3/4/11 - I used a USB car charger (link below) to charge my Captivate with a USB cable known to be working (had worked on my Captivate before, works on my brother's Captivate). If you're asking why I used that charger... well I got it for free with my E-71. I'll never use it again. Anyway later that night I tried to charge my phone on my official AT&T A/C charger but nothing happened - the phone acted like no USB was inserted.
newegg[dot]com/Product/Product.aspx?Item=N82E16882923001
Sorry for the bootleg link, this certainly isn't spam but I'm not allowed to post links yet.
Since that date, my Captivate won't charge via AC power cord. My PC won't recognize it either, but here's the weird part - my phone recognizes when it's connected to the PC via USB. For example, I can connect the phone to the PC and it will state "USB connected" on the Android pull-down (top) menu. Since I have mass storage chosen as the default, it will give me the option to send or receive files from the PC from the same menu. However, if I attempt to actually take that option, the pop-up menu which allows you to mount your memory cards does not come up. In addition, if I have the phone in USB debugging mode and I connect to my PC, the phone recognizes that as well. The PC does not recognize the phone in any capacity, at any time. No matter what I've done so far it will not charge via A/C.
Background: I've had my phone for a little over 6 months now, I've been running Cognition 2.1.6 since about 3 weeks after I got it - before this problem I haven't done any modifications whatsoever since the first load of Cognition. My PC is Windows 7 Ultimate 64. To rule out a bunch of other things, I've tried to use multiple USB cords that are known to work with a different Captivate and my Captivate prior to this problem (3 to be exact), I've uninstalled and reinstalled all Samsung's drivers on Windows, and I actually reinstalled Cognition using the three button recovery mode. To further rule out external problems, I just put Serendipity on my brother's Captivate using the same USB cord and PC that I'm attempting to use with my phone. He had been using the exact same version of Cognition I was.
I of course tried to revert the phone to stock using ODIN in order to fix the problem. I attempted to use the two button method (hold volume keys and insert data cable from PC with Odin running) but of course since the USB is not working properly that didn't work. It's worth noting that the described method worked perfectly for my brother's Captivate to revert to stock in preparation for installing Serendipity. I attempted to manually unmount and remount my memory cards several times, change USB modes between mass storage, Kies, modem, etc - nothing seems to work. The phone seems to be completely normal except for this USB issue. One last thing that's strange is if the phone is powered off and I have the USB A/C charger plugged into it, I cannot turn it on. When I hold the power button a relatively small spinning circle comes up after a second or two near the top of the screen. It disappears when I release power. If I remove the USB cable and hit power again it powers up completely normally.
Because of all of the above, I'm 99% certain that the issue is with my phone (not from any other external source). My only uncertainty is whether this is a USB hardware issue or a software issue where the phone is trapped in some sort of limbo due to being in a quasi-data mode which is causing it not to charge via A/C power and causing the PC not to recognize it. Has anyone had an issue remotely like this? I've come to terms with the sinking feeling that this is a hardware issue and that the only option I'm going to have is for my phone to be accidentally run over by a car (in order to pay my $125 and get a "new" phone under AT&T insurance). If anyone has any suggestions I'll be more than happy to try, maybe we can get this thing fixed!
If you made it this far I'll just say thanks for reading my wall of text and thanks in advance for any advice you have.

Were you able to get this issue resolved? It just started happening to my Captivate earlier today, and I was hoping that a solution had been found.

I haven't been able to get it resolved, I actually just sort of gave up on it and went back to my old phone for now. I have insurance so I'm not totally screwed, but it's not that cool obviously.
Were you able to get anything resolved on your end? If so I'd love to hear how. The one good solution would be a package to restore to stock that you could run through update.zip on a memory card, that isn't available yet is it?

i have this issue as well. I flashed Cognition 4.4 and it ran just fine for a couple weeks and then it began not even recognizing the micro plugged into any power source or the samsung dock! debugging on or off, battery saver apps removed, all that. multiple reboots. nothing. it takes a spell of, if i'm lucky, recognizing it after i eff with it for a few minutes and flukes a decent charge but at night, it usually has a loop cycle charging effect. I can hear the "boop beep" charger plugged in sound over and over throughout the night.
i use the phone in my cars and everywhere with the same problem.
no resolution! HELP!!!

I came across the same problem with USB on ARMANI I9010 after installing Cognition5. The most unpleasant is that i have bought it abroad and there is no possibility to return it
Does any body found the solution?

[Q] Problem with computer recognizing phone?

After much searching and work on fixing my bricked captivate, i broke down and bought a jig from mobiletechvideos.com. It works perfectly as intended, except for the fact that my pc is not recognizing the phone after it enters download mode. As a side note, i may have royally screwed up when i did something in clockwork recovery, where now i cant even get past the ATT World phone boot screen. Im afraid i may have deleted anything that can mount the phone to the pc. I have already installed the proper drivers, I think. Anything i can do to fix this?

So it shows the world phone screen a bunch of times? Plug it into an outlet see if the green battery comes up, just wait for it, the Gray battery will do a short of loop a few times... Once its at the green battery try to turn the phone on, be patient too, if you get the phone on, go to settings> privacy then factory data reset, make sure you backup to external or computer first
Your welcome
Now you say/press thanks
Teaching manners one person at a time

Thats not gonna work... nothing i know of can be done to it. it doesn't move past the att screen. No animation, not sound. Just ATT World Phone. i can get into download mode, but cant connect to computer. Thats the problem right there.

Try restarting your computer? I've had similar issues on a yucky iPhone, and I've read about other Captivate users with it as well, and a restart helped resolve the problem.

Go under your drivers and uninstall them and reinstall them it helped when I finally had got mine "back to his construction job" (lol download mode) it should then work

Ive already tried another PC and Uninstalling and reinstalling the drivers to no avail.
It just like the phone isn't even there. It will charge, but wont mount to the PC.

Not trying to insult your intelligence or anything (I might actually be insulting my own) but you have Odin open, right?
Just trying to think of anything lol

Yeah, but it wouldnt matter anyway if the computer doesnt know its there.

Try cleaning the mini usb port. Or switch the usb cord connector the samsung factory one tends to break the data + and -.
As for not getting past the at&t screen. The kernel you installed cannot read the system partition probably corrupted or the kernel you installed cannot read ext4.
If you cannot get it to be recognized send it back to your carrier for repair, should be under warranty.

Thats what im doing now. Thanks for the help, though.

You sure you have the proper drivers installed for your phone? The links for them are on the odin forum in captivate development

Stuck at "Samsung Galaxy" boot screen, cant get into bootloader, computer wont detect

Stuck at "Samsung Galaxy" boot screen, cant get into bootloader, computer wont detect
Hey everyone this has been a huge hassle for me for the last few days and was hoping someone could help me. I have had to resort to using my HTC Legend...which I love but it doesnt have what I need.
I was in recovery the other day trying to load a custom rom through the CWM and I went through and accidentally hit "format system". I couldn't cancel the process so I knew something bad was going to happen....I reboot the phone and for the last 3 days I have had it plugged into the Usb charger with no luck of booting, it has been stuck at the "Samsung Galaxy S 19000M" boot screen and no further. I took the battery out and tried rebooting it after a few minutes. No luck with this either, still stuck at the Samsung screen. I CAN get into "DOWNLOAD MODE" but I CAN NOT get into recovery/bootloader (hold volume up/home button/power button).
I have put it into download mode and and plugged it into the computer (I am running Windows 7 64-bit) and it will not detect it. I have all of the correct drivers, I know this as I have a friend who owns the exact same phone and my computer detects it just fine. Odin nor ADB will detect that there is anything AT ALL plugged into the computer. It does not even come up as, "android device", or "storage", there is nothing, nota, it is as if the phone isn't even plugged in. It will not detect in "download mode" nor while its stuck at the "Samsung Galaxy S" screen, and yes I have tried a different USB cable, and still nothing..
I am quite capable with electronics but I cannot find anything on the internet as of what to do. Is there anything that I could load on an external SD card that would force the phone to flash a ROM with new kernal and modem? I think the phone is empty that is why it is not booting, as if there is nothing to load on the phone. Is there anything at all that anyone can think of??? I am completely stuck. I wanted this phone to last until the Samsung Galaxy S 2 was released here lol.
I'm with Virgin Mobile Canada. Thanks!

Cant you get it into Recovery mode?

Have you tried heimdall?
You will have to follow the instructions coming with it to the letter (about installing some custom USB-driver).

Hey, I will search for that right away and let you know how it turns out. Thank you!!

well if you have download mode then dont panic.
just flash a 3 file firmware along with pit file and re-partition and you will be fine

How can I flash any firmware if my PC will not detect the phone? When I plug the phone in there is nothing. Odin doesn't detect the phone, Keis doesn't detect the phone, ADB does not detect the phone, and I just tried Heindall, and it does not detect the phone..... Maybe the actual hardware for the USB plug in is faulty in its self, in which case I am screwed.

i see..... i only read the last 2 posts and im always telling people off for not reading properly
have you tried the obvious steps such as
Un-install - Re install Kies
Run Odin as administrator
Tried Alternative USB port - direct into the PC motherboard
Finally a different PC all together
hope you can get it workin hate to see another broken SGS

I have tried, uninstall-re install of kies, run odin as admin, alternate usb port, anddd I tried plugging it into my laptop...no luck...this absolutely driving me nuts because I know the phone cant be bricked, if I can get into download mode I SHOULD be fine but for some strange reason the phone seems to be undetectable...ahhhhhhhhhhhh if only there was just some way to access the internal storage or a program that would force a flash through an external SD....

I am going to try loading Ubuntu on my computer on one of my HDD and see if it will detect the phone. I am assuming this is my last option and I have high hopes as Ubuntu detects almost anything...I will update...if it doesnt work I might be looking into taking apart the phone its self and intalling a new USB plug in on the phone motherboard...

im not sure of any other steps
last resort.... have you tried another USB cable ? like your friends cable that he uses for his phone ?
EDIT: if i was you i WOULD NOT take the phone apart.... if you do and it does not work, your warranty will be void,
at least if you cant get it working you can send it off for repair and blame kies, you will have a good chance of getting it fixed by samsung than you would yourself

I dont know if it has been opened already by someone else. I bought the phone for $180 CAD from a sort of "2nd turn" site. As in it was being sold as is. The phone problem reported by them was that the USB connectivity was not working. When I originally got the phone from them everything was working correctly, except the USB connectivity like it stated. It came ROOTED and loaded with the leaked version of Froyo before it was out so I automatically assumed that was causing the USB problems. I got around to changing the ROM with a reported working USB using CWM. But, still no luck with USB connectivity. I just dealt with the problem and flashed everything through CWM. Which led me to this...ugh
Is there supposed to be a warranty seal behind the battery cover? Over the screws like there usually is? Cause I see nothing..

thats not good news.
there is no warranty sticker, but samsung could find out if the phone has been opened.
It depends on the actual repair guy, to be honest, samsung will have 100's of phones to repair daily, the majority just get passed on - flashed - wiped - boxed and sent back to the owner.
however if some (P)Rick is having a bad day and wants to find out why the phone is in for repair, and he finds out its been opened up, or its had custom firmware, then he can refuse to fix the phone or send it back to you with a bill included lol.
so you have to have a good excuse incase the worst happens.
if you dont fancy your chances and you feel capable of replacing the USB yourself then hey go for it !!

Well thank you for all the help. I am going to try installing Ubuntu first and see what happens, I have never had any driver issues with that OS EVER so if its detectable, Ubuntu will be the one to detect it. If that doesn't work I might take my chances and send it in. And if like you said that one person decides to screw me over, they at least have to send it back to me, in which case I will just open it myself and change the USB plug in like I said. (which might not even be the problem...)
Is there anyway to tell on the out side without opening it if it has indeed been opened before???

erm..... i dont think so, but i dont know what measures samsung have took to find this out.
if it was me the obvious things i would look for is, damaged screw heads and scratches down the sides - where the casing has been prised open. other than that i would not know what to look for
either way, i hope u get it fixed

Well I sent my phone in to Samsung last week and I just got it back today! I opened it up and I guess the problem with the phone was pretty bad lol they just gave me a new phone, I was thinking it was refurbed but it said right on the repair receipt "condition=NEW" I am extremely happy.
That aside, do you know if you can use the SGS II if it is unlocked in Canada?

HTC One USB Port Problem

The phone USB port is having problems. It will charge ok wont connect to any laptop in any mode, system, fastboot or recovery. It would be powered by it for a small fraction good enough for it to be detected and then it would stop sending signals. Anybody know any fix for the problem.
Also has anyone sent their rooted phone for repair recently n got it repaired under warranty. Its revone S=off and running trickdroid.
And the error in device manager is USB BOS descriptor failed, "waiting for device", "Device cannot start. (Code 10)"

its probably the voltages messing it up. On connecting the USB it turns on car mode. I was able to briefly get the UMS to work by draining down the battery n connecting to laptop n turning it on. It worked for 2-3 boots and thats it. Its gone again...

i'm having almost the exact same issues you are. it won't charge unless it's turned off, and it won't connect to my computer at all. sometimes if it's plugged in it'll put itself in car mode. did you manage to get yours fixed?

Same problem here! I made a thread about it but no one answered..
I'm glad it charges though, yesterday when I went to bed it wouldn't charge, but this morning it did. Goes into car mode though and it won't connect to the PC. I think I'm going to bring it back for a repair/replace under warranty.

i fixed it, tried different cables and chargers and finally the charger from my old old moto cliq fixed it, i think it was short at some point of voltage troubles. Fixed since some days now. No more trouble. Also discharge ur battery a few times ( turn of fast boot from settings) and charge all the way to 100 for like 3 days. Also try booting in fastboot mode and connecting to computer see if fastboot usb is connected. took a few days to get it work using different methods. Dont exactly know which one worked

i went in to my t-mobile store to get the warranty replacement process started this morning, but of course the rep saw that i had clockwork installed on it and said he couldn't start the exchange until i got it back to stock. problem is, since it doesn't talk to my computer i can't access adb to reset my tampered/unlock flags and flash the stock recovery. i'm probably gonna have to throw down $175 to asurion to get it replaced for "water damage" or something, unless you guys have any other suggestions i might have overlooked. when i get home i'll try a bunch of different microusb cables to see if i can get any to work, like charnsingh_online mentioned.

just wanted to toss in a quick update in case anybody else is having this problem... a few hours ago someone posted about this same issue on the HTC One subreddit, and i came across a post on the vodafone forums from today describing it as well. i'm getting a little concerned that there might be a bad batch of these phones floating around that are all beginning to fail.

Quick update from me aswell
Yesterday evening it charged like normal, I could even pull the plug out and put it back in without the phone going in car mode, it would still charge.
Now this morning I wanted to try to see if it connects to my PC but that still didn't work. I put it in the charger just to see if it still would charge as easy as the evening before but it went to car mode and I was back at the beginning. Turning the device off and back on didn't resolve it.
Now it does charge again by turning off fast boot (or however it's called, I'm translating from dutch). That made it work again (but for how long?!)
EDIT
My phone finally connected to the PC. The phone still went into car mode but it didn't disconnect after that (like it used to do). I can put my music on my phone now but the phone is alternating between car mode and normal mode.. pretty odd.

I have the same problem. when I turn on the htc one, rainbow screen appears, and does not detect when I connect to PC, I will test the battery discharge, hopefully get lucky,

I'm having the same issue as well. The phone randomly now is throwing itself into portrait mode even when I don't have it plugged in, charging is very intermittent. I'm thinking there's a short somewhere on the circut board but that's only a guess. Do we think this is a hardware issue? At least I'm still on stock if I have to get the phone replaced, but what a PITA with not having an SD card to remove. I'm liking that less and less... grr.

may be a defect, i had a few cells and never appeared a similar problem, I had a galaxy s2, s3, s4, HTC Evo .
I detected car accessory mode, and the strange thing is in Fastboot Mode I can install an official RUU from my PC .

I'm thinking of a theory, it could be that the MISC partition mmcblk0p19 apparently damaged as happened with the HTC Desire for a while now, if reflashing That possibly corrupt partition with a fresh htc ONE, I'm digging into this line of research

OTG mode?
Have had Htc one x + from ebay for a week with no sync or charging problems then yesterday tried to sync but phone crashed/rebooted and asked to send error report to htc for "abnormal restart" or somthing and my pc saw it as an "un-recognised device", since then it is not even seen by my pc and will only charge when off or after restart. The usb is putting out 5v which it should only do in OTG, using an otg cable it powers flash drives ect and see's them. If I can't fix this it will go back to HTC under warranty.

Run phone down to 2% battery then checked and no more 5v output from the usb port,turned phone off and still no output voltage from the usb. The phone now charges and connects to my pc as it should. If the battery was removable as it is on other phones it would have done the same as discharging the battery on the htc one x + to give it a propper reset.

i went in to my t-mobile store to get the warranty replacement process started this morning, but of course the rep saw that i had clockwork installed on it and said he couldn't start the exchange until i got it back to stock. problem is, since it doesn't talk to my computer i can't access adb to reset my tampered/unlock flags and flash the stock recovery. i'm probably gonna have to throw down $175 to asurion to get it replaced for "water damage" or something, unless you guys have any other suggestions i might have overlooked. when i get home i'll try a bunch of different microusb cables to see if i can get any to work, like charnsingh_online mentioned.

im looking at the same options too man... would have to pay $150 or so to get a brand new one from rogers unless they sent my phone from repair without noticing the unlocked bootloader. from what ive seen theres no way to relock it and flash the stock recovery aaaand RUU without computer connection.
looking at my situation now, im considering never rooting again just because of how screwed you are if something happens to the hardware.
i havent really considered replacing the usb port myself but i guess if i found a store where i live that can do it for a reasonable price, imma go for that.

Man, you can flash it, if you have the same issue as me, i was able to flash in FASTBOOT MODE, and relock with renove , i used ADB WIFI from MARKET , with this app you are able to send ADB commands , adb shells, etc for REVONE S-OFF, or apply a RUU original, in FASTBOOT MODE your PC should detect connections.

well last night my computer wasnt picking it up in fastboot mode and i have all the drivers from when i unlocked a couple weeks ago so it should be recognized. but i guess i could atleast try relocking it. and cant i just get rid of root straight from the device?
do you know what command i would have to do through adb, ike fastboot oem lock or is it different?

Amm, have you used renove for s-off?? If you use fastboot oem lock maybe you will get the relocked mark or tampered maybe with Revone you can roll backto a clean locked and s-on state

my phone is unlocked but is still s-on. how would i get back to stock 4.1.2 and no root after if i can relock my boatloader using that wifi adb?

look, if you lock the bootloader again being in S-ON, you will receive the label relocked or tampered with this you might void your warranty if you send it, the option that I can think, make S-OFF with REVONE, Read a little this thread : http://forum.xda-developers.com/showthread.php?t=2314582
You can fully use ADB commands via wifi, tested by me, with REVONE you can LOCK the bootloader and back to S-ON , with no trace of having changed either BOOTLOADER or S-OFF/S-ON .
