AW: [TUT] Downgrade/Unbrick Ville S4

Wrong.

The phone has lost the device node (whatever exactly that may be) so the partitions are not visible anymore, but they aren't erased. Everything is still there and also the phone state will not magically reset from this. They can tell exactly what happened if they want to.

Yes, the latter I have heard too and its even got a name: JellyBean Brick.

The 2.15 hboot can be downgraded though. Not a problem. Quite a few seem to have done it. I went backwards from 1.13 though, so can't add my own experience...

[HTC One S] adolfo778:
Hey sneaky my one x was fried a couple of weeks ago. Used a cheap car charger and boom fried. It was able to be detected as a qdl device but no partitions . Long story short I called HTC said the one x didn't turn they didn't ask questions and said they can send me a label to ship it to them they didn't ask any questions just asked for the s/n

I ended up selling it in a trading forum cause lack of time but the guy sent it in and its in repair

Sorry for the long response but that can be an option for you if all else fails
[HTC One S] theguitarman94:
Thats what I wanted to hear! I knew I was doing everything right. It's a shame but it shows really that if something isn't broke. Don't try and fix it. That's a phrase that I never pay attention to lol!
[HTC One S] mycomputerisjunk:
I'm in the same boat. The downgrade went fine but the phone never restarted nor did the charge light turn on.

Anyway, I sent the phone to HTC on Jan 4th and according to HTC's site, they are still waiting to receive the phone. :confused: I think this may just be a lost cause for me. Damn I loved the one s.
[HTC One S] theguitarman94:
Oh ok, I'd imagine it's quite a lengthy process to find out and that they don't often bother. I've seen loads of cases where they've fixed phones in qhusb mode and if they don't fix it they blame it on something else. If there is no hardware damage they probably just do a board swap. To brick a phone ironically you have to know more than the average joe does. I'd imagine that because they get a minuscule amount of devices that have been bricked they just don't bother to research into them. I'm hoping I'm going to be lucky
[HTC One S] Animoski:
Thanks so much for the tutorial, worked fine for me! Downgraded from 1.14 to 1.06 without a hitch, no issues so far :)

Thankfully I understood to supply my own p4 backup and not use the supplied one, SuperCID bricks your phone if you get the JB OTA apparently :/
[HTC One S] Flipnfr3ak:
how do i get my own p4 backup???? im new to ubuntu

[HTC One S] Sneakyghost:
Thanks bud that was a REALLY helpful answer, the Car-Charger thing is just brilliant! Sorry to say that i don't like to make up stories so i discussed the matter exactly how it was with support and of course THEY where then not saying the truth by stating that they would have to stick with the warranty rules. I know for a fact that support can make off-the-tracks decisions which lead to repairs actually not covered by warranty but this time, they where totally stubborn and where not moving an inch.

So, i ended up with now sending it in and waiting for the Arvato-Diagnosis, as Arvato has the right and responsibility to judge and decide on behalf of HTC. What a crap statement! I've never before heard of Support not being allowed to override the Service-Center diagnosis and decisions.

So, they where just playing stupid, stubborn and unhelpful.

I left a negative feedback afterwards as that usually leads to their Escalation Team in Frankfurt to call me up. So i am expecting a call any day now asking for why i was not satisfied and that team then may be willing to grant me some grace.

---------- Post added at 03:26 PM ---------- Previous post was at 03:17 PM ----------

Usually, if you play stupid noob and more or less cover your tracks, e.g. flash the right RUU after a downgrade first so all software components match up and the downgrade turns invisible (not sure it actually does because i suspect one partition won't ever be flashed but logs all activities) you are pretty much on the safe side i believe. I have seen loads of successfull support cases like that.

However, i decided to go the truthful, straightforward way because i am also engaged in an "official" contact with HTC people and i don't want to ruin my position with them by appearing as a lying prick. I have also asked for help there. So i guess if Arvato refuses to fix it because they know what the phone went through, i will just receive it back.

We are actually discussing to do a donation rally for a Riff Jtag Box for Tecardo, so he can help out the european users, or at least the german ones if they brick their units. Will see how that turns out. If we manage to get a box for him he can fix up my device for postage costs.
[HTC One S] Flipnfr3ak:
If its during the process then no....... I like to try and get my files and back ups before doing anything. Ill re read the post. Thanks

RIFF jtag Box Unbrick Service for XDA People

Sorry for hijacking your Thread with this, Grim: :angel:

Tecardo and me have set up a quick donation post for getting a RIFF box for approx 120 EUR /160 USD to jtag bricked devices.

Tecardo will offer an unbrick service to XDA People for a donation or some small reasonable price or so. Not clear yet. The box is already nearly bought by the looks of it but if anyone here needs help he can do so by contributing.

Only downside: researching postage fees brings up the fact that offering an unbrick service to anywhere outside the EU makes hardly no sense because of the costs. So this is probably more interesting to EU users and those who think they want to help the Venom Team maintain their testing and development devices.

:good: Here's the link to the Post: http://goo.gl/P6gJg :good:​
[HTC One S] adolfo778:
Don't think you can ship batteries overseas through USPS(learned from when xda had the marketplace). And other carriers such as USPS will charge Bout 40 bucks for shipping. A shame yes but like you said good for the EU users . Think you guys should have two people with them one here and one in EU

Ok you are sure that is sdc12 and sdc4 ?

If yes, you began again from step 2

2. On your first window, type

don't do step 3 and 4 if you are sure that sdc12 and sdc4

then the rest of the tuto.

Do not hesitate to restart the computer if that still blocks

But have you do this before restart pc:

If it stalls at "Waiting for /dev/sdc12, hold the power button down on your phone about 10 seconds, or until your see "Qualcomm. Inc. Gobi Wireless Modem (QDL mode) disappear from your terminal window, then release it. 10 seconds or less after you do this, emmc_recovery will see your phone and proceed.
[HTC One S] Tyler DeLarge:
guys, perhaps i understood my problem!

in practice, the file bakp4 that I considered is the file that I found in the folder "ville" but I have not replaced the numbers putting my imei

this is a serious problem?
[HTC One S] danirebollo:
bakp4 is file inside "ville" folder if you can, but then you need to put your imei instead of default, but if you make your own bakp4 you dont need to change nothing.
[HTC One S] Tyler DeLarge:
i do this:

but the file i thought that it was in PC and i do nothing(instead it was in phone right?) and so in future passage i must use bakp4 with my imei

Happened to me too, umm your sticker near the sim tray may have your IMEI. And look a post #252
[HTC One S] Tyler DeLarge:
oh, all is ok but at the end of last passage the charging light turns NO back on. why? D:
[HTC One S] Qs5:
EDIT: Before you start make sure you do step 8 again.

$ cd Desktop/ville

"or you can open a new terminal window and run the following command IF AND ONLY IF the phone doesn't reset out of QDL mode

Code:

$ sudo ./emmc_recover -r

10. Once that is finished. We have to reset the qcserial driver again.

Code:

$ sudo modprobe -r qcserial

11. And then recreate the block device

Code:

$ sudo mknod /dev/ttyUSB0 c 188 0

12. Now we restore the original mmcblk0p4 that you should have saved as "bakp4"

Code:

$ sudo ./emmc_recover -f ./bakp4 -d /dev/sdc4 -c 24576

13. Again, if it hangs, hold your phone's power button for about 10 seconds, then release. This file will flash very quickly (it's only 1K) and once it completes, you'll immediately notice that your charging light turns back on. You should see "Qualcomm, Inc." or "Qualcomm, Inc. Gobi Wireless modem (QDL mode) disappear from your terminal screen.

[HTC One S] Tyler DeLarge:
up guys please
[HTC One S] Sneakyghost:
Well dude to be quite honest it is incredibly hard to help with such strong language difficulties. You have to understand that this process is very delicate and not very error tolerant. If you do things wrong you can end up with a dead device.

You are better off find someone who can explain to you in spanish.

Regarding the quick changing back to QDL mode: i think that's when your device is finally really bricked. Why? because i had a "Normal QDL mode" where it always had enough time to flash the next chunk of the hboot. Then two weeks later, when the device fully bricked, i tried to recover it with a little tool from unlimited.io that resets something in the chip and after using that tool, i also had this rapid changing QDL/no QDL mode. At that point, nothing worked anymore. Well, basically i already couldn't see the sd* partitions anymore already before, so not too sure but i think what you are seeing is a brick. Don't think you can still recover. But please find some spanish speaking dude who can help you properly.

Sorry man, under your circumstances, with your language and such, you shouln't have tried. I respect your courage. That was a strong move. Good luck. You could send your Phone to Tecardo (Germany) but thats gonna be a long journey for your phone and quite exensive...

PS: we still need a few bucks for the unbricking device, guys! Here! :D http://xdaforums.com/showpost.php?p=36872188&postcount=11

Hi danirebollo

your technique is interesting for the last step !!!

Even if the phone has the black screen we can use adb shell command ?

Non need to be on bootloader or with phone not blocked ?

If Yes your technique must be include in this tuto !!!
[HTC One S] danirebollo:
I think must be inside phone, on the back of the batery

---------- Post added at 08:02 PM ---------- Previous post was at 07:54 PM ----------

Now i got fully functional phone and i dont try this XD but i try to ask you xD:

I dont remember if adb see phone with total black screen. I remember that, when phone isnt "QDL" (in my case it shows "HTC") i would push volumedown/power and it boot into fastboot and now it connect to adb.

Make sure that your phone isnt power off when terminal not shown "QDL"/nothing
[HTC One S] krzysiek033:
I'm having the same problem as Tyler. I did everything as tutorial say but after the last step phone stays in qdl mode. hbood flashed fine so is backp4. Phone wont show up with "$ ls /dev/sd*" anymore, so I cant flash anything again, its just "wainting device"
[HTC One S] danirebollo:
what?
[HTC One S] Tyler DeLarge:
aditya says to use teamviewer, but i don't know use it
[HTC One S] danirebollo:
Guys, if you have any error, starts from the beginning.
[HTC One S] Tyler DeLarge:
yes but when i connect phone to computer, it goes immediatly into QDL mode. if i have to hold power for 10 seconds, it disappear and appear again immediatly. and so i can do nothing
[HTC One S] jac10000:
Can you reboot phone on bootloader ? If yes try the danirebollo 's trick by using windows and adb shell command

http://danirebollo.blogspot.fr/2013/01/htc-one-s-unbrick-downgrade-hboot_17.html

with windows and adb shell:

1: adb push mmcblk0p4 /sdcard/mmcblk0p4

2: adb shell

3: su

4: dd if=/sdcard/mmcblk0p4 of=/dev/block/mmcblk0p4

---------- Post added at 09:29 PM ---------- Previous post was at 09:16 PM ----------

Ok , if i understood well , you can't do the last step by ubuntu, the phone stay blocked with your charging light off. you can also restart the phone on bootloader and by windows and adb shell you flash the mmcblk0p4

Very good trick !

it's possible, I think that bootloader don't need of mmcblk0p4 to work and we can flash it with adb

---------- Post added at 09:42 PM ---------- Previous post was at 09:29 PM ----------

ok i see you are blocking at the last step , try also the danirebollo 's trick
[HTC One S] krzysiek033:
NO, I can't go into bootloader. black screen all the time.
[HTC One S] danirebollo:
do not have to see "QDL" and hope to stay there. You have to put commands in the terminal just as you see the directories (sdc4/sdc12), THEN you press enter, not before.

---------- Post added at 10:02 PM ---------- Previous post was at 10:00 PM ----------

what you see when put "watch -n 1 lsusb" in ubuntu's terminal?
[HTC One S] krzysiek033:
I see "qualcom, inc. gobi wireless modem (qdl mode)". If I hold the power it disapear, shows up as "qualcom, inc." for 2 sec and goes back to "qualcom, inc. gobi wireless modem (qdl mode)". I cannot see the partitions "$ ls /dev/sd*" at any time.
[HTC One S] jac10000:
which hboot have you before ?
[HTC One S] krzysiek033:
1.14
[HTC One S] jac10000:
when you type the last command you have "waiting devices" ok, and you hold the power button down on your phone about 10 seconds and the flash don't proceed ? have try several times to hold the power down ? have you try to unplug and replug the USB cable ?
[HTC One S] Sneakyghost:
I don't think his device will come back online. If it is switching between Gobi Wireless modem and QDL mode within 2 seconds, its like my phone. It won't come back. I have tried virtually everything i could find on the internet. Chances are bad.

Probably a case for HTC service or Tecardos RIFF Box... just saying... :D

Not promoting anything but Tyler should go looking for some Unbrick service in his country.
[HTC One S] danirebollo:
Did you update ls /dev/sd* all time? This window dont auto update

Im about to downgrade from 1.14 Hboot. I had one question. This JB OTA... Does it update the Hboot to 2.14? or can one take the JB OTA and still have Hboot 1.14 (im not certain if my previous owner took the JB OTA.)
[HTC One S] theguitarman94:
If someone has installed the jellybean update and your phone is on the newest HBOOT apparently there are problems I've tried to downgrade after JB ota using this method and I permanently bricked my phone (completely dead and unrecoverable) I don't think it's worth it unless you are certain. Even then the chances of error are still there EVEN if you know what you are doing (I do and I still ended up with a brick)
[HTC One S] danirebollo:
Are you sure about this? Linux/windows not find nothing when you plug phone? Even when you pull power and later relase?

I heard about brick when install JB OTA with 2.xx HBOOTs, but maybe this brick would be fixed with this unbrick method, not??

Bad news firstly his emmc_recover cant see partitions

when in QDL mode i pressed down power for 10 seconds the qualcomm inc. in lsusb did not flash but in his case it keeps flashing disappears and reappears every second .

No partition can be seen

i think he needs a JTAG or HTC service
[HTC One S] Darknites:
Dude there is no point bumping it up when its always at the top lol.
[HTC One S] jac10000:
I think he should try with a livecd or on other computer . Can be a problem of USB port ...

which version of ubuntu have you ?
[HTC One S] Tyler DeLarge:
no usb port problem. before i did the procedure
[HTC One S] Sneakyghost:
I said it already. Your device is most probably in the same situation as mine. It is dead. You will need to either convince HTC Support to fix it for you or find someone with a JTAG device in your country.

I just had a 20 Minute call from HTC Complaints center in Germany but it was just a waste of time. They're not gonna do it unless i pay them.

You can also consider to contact the RIFF JTAG BOX project from Tecardo and me and then send your phone over to Germany to have it fixed by Tecardo. But that's gonna cost you some postage fees. Its about 11 Euros with DHL and insurance for one way. So it would cost you about 22 Euros sending it to Tecardo and back, plus - that would be nice - a donation.

HTC One S JTAG repair in italy can be purchased on ebay. there is one guy here: http://www.ebay.it/sch/i.html?_trksid=p5197.m570.l1313&_nkw=htc+one+s+jtag&_sacat=0&_from=R40

It costs you 45 Euros plus 12 Euro postage... I'd say thats lot more than sending it to Tecardo and donating a bit.

Those are your options in my eyes.
[HTC One S] Tyler DeLarge:
but HTC did not fix your phone?
[HTC One S] PeQuEsan:
Why did you tell HTC you were messing with HBOOT (did you?)? It would have been easier just to say you had a fail applying JB OTA for example... ¿¿??
[HTC One S] :
Tyler , Sneaky is honest to htc as he is in official contact with them so he told them he has tampered with the phone so they might refuse but as you talked to htc via chat and told them it died while charging and never came on SO there are many chances they could fix yours IF HARDWARE IS NOT TAMPERED:silly:
