Hello,
I tried to update the radio and the SPL version on my Tattoo. Everything went fine until I had to reboot my phone. It shut down alright, but it never powered on again.
These are the following problems I am having with my Tattoo at the moment:
Cannot power on phone.
Cannot boot into recovery mode.
Cannot boot into FastBoot.
When I connect it to my computer via USB, nothing happens.
The only thing that it's responding to is when I connect my it to my charger.
Does anyone have a solution or is my phone dead forever?
Thanks ahead!
bump? anyone?
Send it back to HTC. If anyone can do anything about it they can. There's nothing else you can do. Sorry
boo.. that sucks..
Well, thanks anyway
Ehm, I don't want to post a New Thread so I'm gonna ask here:
Does anyone have the pinout for the Tattoo?
Take a look at this. I guess they fix such things (but you never know if they just are after your money. http://www.ort-jtag.com/index.php
Yeah I saw that already. Also, there is a file name Tattoo Jtag on their website in the Support section. However, to access that section you have to enter your products serial number (which is I'm guessing the phone's serial number). I have tried several serial numbers (including mine) and all of them were 'invalid' so I never checked the files out.
Also, they only have one thing in the shop which is a kit and it costs $330 so no thanks
I have a similar problem, I would like to share my knowledge although I must be completely out of way.
My experience is based on the BeagleBoard and Angstrom so I really don't know the HTC HW and Android at all...
- The device boots from an xloader that instructs the device how to proceed with the boot
- the bootloader takes place (great u-boot in the beagleboard ?? in the HTC phone) the bootloader allows for ROM or kernel+rootfs flashing and much more
- now the kernel is loaded.....
User mode applications do not allow to have access to the memory area where xloader and u-boot lie so they should be safe all the time to allow for device reflashing.
So we should have access to the device via bootloader anytime if we knew how... maybe somebody can help us further.

Same here...Exact same issue...No Recovery mode...No USB Connectivity, Screen turns on but is blank, alhough I did see Tattoo popping up initially but not any more...All I can see is the LCD back light turns on...Battery does charge...Also when I try to enter Recovery mode screen keeps blinking as if it is trying to restart again and again...Someone help
similar problem here, but i get absolutely no response from the phone, it doesn't even recognize the charger. do i just throw it away and buy a decent one or is there a solution?
Sparky the only way for now to fix that click is to bring it to some service point that have that ort jtag, because only way to fix that is to writte new boot sector on phone . Im sure that i know at least 2 services that have ort jtag in Novi Sad . Look for marvel *Miroslav in Ns, or send me private message
same thing happened to me
just this morning, and in desperation I tried hard to remove the batt cover (prob pressed some of buttons, I felt a jerk and ho it was back in amon ra`s recovery, nect time I just removed the battery waited for 30 secs, then press off&home and hold it till recovery came back) but for good half hour NO REACTIONS , ABSOLUTE BRICK, nothing when I put the usb in PC or in socket, dead screen, no sounds and no reaction to ANY combination of keypress. I guess you could call me lucky (in last few days I flashed at least 3 versions of froyo roms, this afternoon I bought =8GB class4 Kingston, formated it in PC FAT32 default size, copied EVE. from my 2gig rom then just turned it down (yes I am brave) and put the 8gig in tattoo, it works like a charm (finger crossed it will continue)
So is there an available Jtag for the Tattoo yet?
I'm in the same situation. No recovery no fast boot, Damm!
I`ve update psfreedom with psgroove_hermes_v4 zip file then my tattoo reboot and now I only get the Tatto title screen but nothing happends.
Somebody have clue to give back life my phone.
Thanks!
if you can get to the title screen, that means you can connect it to your pc via USB and recover from a backup (I hope you made one)

You have to enter in fastboot.
Hold volume down and turn on phone.

Heya!
I bought a demo LG Quantum for a song today and I've been trying to remove the Demo software by following these instructions:
Through work aquired a Mozart with Telstra Demo(Store) Rom. Very furstrating as it wouldnt hold settings and kept playing that damn video.....
Downloaded this rom (following the links from here and trying a few download mirrors until I found one that worked)
Turned off Phone
Held Volume Down Key while Pressing Power Button (This turns the phone on and launched Bootloader)
Connected to PC Waited about 5 minutes while Windows auto detected the drivers and installed what it needed
Right Mouse clicked on the downloaded Rom and selected "Run as Administrator"
Followed the prompts.
****NOTE**** When it got to 10% the phone rebooted - LET IT!!!!! DO NOT TOUCH IT DO NOT DISCONNECT IT - Just wait -The computer will redetect and about 10 Min later VIOLA - All sorted nice and clean WP7 HTC Mozart (with a with Telstra One Hub - which aint that bad) - Whacked the 3 Sim card in - Downloaded Connection Setup Wizard from market place and a few minutes later was sending and receiving MMS etc
Click to expand...

However, I don't know if this applies to the LG Quantum since I can't seem to access the Bootloader screen and the ROM I can't find an executable ROM file like the one he refers to.
Has anyone resolved this problem on their Quantum?
Could you help me through it?
Thanks in advance,
-Aylmer
Nevermind! I was trying to flash it, but, in the LGDP2 Flashing app, I was plugging in the phone before pressing start!
Oups!
If you're still having problems, the other trick is to use the drivers from the LG Mobile Support Tool.
I got mine from eBay for $100...it is a Demo unit. This thread is very helpful and hope to remove the "Device Alive" software and enjoy my nifty windows phone!
As an avid Android and iOS user I look forward to having fun with WP7

Does anyone have the link for the stock rom? I can't seem to be able to download from http://depositfiles.com/en/files/tmh1fz1ed. It always says invalid param. Could anyone post it here or upload it to mediafire or something? Thnx
ok managed to download the LG c900 ROM but installing the LGDP2 gives me the Installshield error , Catastrophic Error. And my LG USB Modem doesn't wanna install
Could you give more detail about the problem?
Also, which version of Windows are you using?
Hi,
I've rooted using the following manual:
How to Root the HTC Desire HD - xda-developers
After that, everything was OK.
Unfortunately I tried to re-root it (just curious), during the process the htc white screen was appeared and the phone was freezed. After plugging it out, when phone is booted, this page is coming and not leave!
I tried to reset using "factory reset", It starts but after reboot, htc white screen is remain!
Can you help me?

Seems like a corrupt or missing system and/or kernel.
Just take a RUU and follow the instructions and then try to reroot.

Would you please instruct me?
The bad news is that the "recovery" does not work. When I select "recovery" in the bootloader a red icon appears in the screen.
How can I change RUU?
RUU (ROM Update Utility) is a executable-setup that needs to be run on your PC with your phone connected via USB.
Download an RUU exe from here. Connect your phone to your PC and run the setup.
Your phone will be wiped clean and restored to factory settings. Try re-rooting using the Advanced Ace Hack Kit.
EDIT:
You can find the latest version of the Stock ROM RUU in this thread.

OK.
Just some questions:
1. which RUU has to be downloaded? -currently, I"m planning to use: RUU_Ace_Gingerbread_S_hTC_Asia_WWE_2.37.707.3_Radio_12.54.60.25_26.09.04.11_M2_release_188759_signed.exe
2. My phone becomes a stone! when I connect it to the PC, just in charge mode while the phone is off. Is it possible to wipe in this situation?!
Thanks for your quick reply.

When running RRU, it detects that the phone is not connected via USB. As I said before the phone's OS is not loaded so it can not process on it.
Is there any low level format for this phone?
Recovery and factory reset are not working through boot loader.
Save starting a new thread.
I'm in a very similar situation where I can't run the RUU as my DHD won't load past the white HTC screen. I can get it it to the HBOOT USB PLUG screen, but entering into the FASTBOOT, RECOVERY or FACTORY RESET sends it to a black screen with a red triangle and an exclamation mark.
When i go into System Info all looks good, however exiting out it says "No image or wrong image!"
I have tried updating the drivers but all that did was bring up Android Bootloader Interface in Device Manager.
Any help would be greatly appreciated.

Ok seems that You are entering stock recovery. Are You S-OFF? If You are then You can flash CWM recovery and flash a custom ROM. If not you will have to flash a Ruu for your cell. Do You know how to find the Cid number?
Got about the same problem here.
Factory reset doesn't do anything. Still got the same Rom problems and NONE of the usersettings or apps are removed.
Also using recovery doesn't make a change.
Flashing an RUU looks promising, but also doesn't do anything.
IMHO it sounds like none of the options above have the RIGHTS to write any information OR the paths they are using can't be found...
please advice..
If you can get to bootloader, try using fastboot. Or try copying a pd98img file to your sdcard and flash it through bootloader.
You didn't mention does the charge led light up when you connect it to your PC.

I did a radio update and then HBOOT
My Desire HD does not boot, it gets stuck at startup, HTC logo white screen, after 2s 2nd vibration volume keys - + does not work when I connect DHD not even recognized by the pc, is there a solution please help me
I tried the UMT, the fastboot by adb, I believe that DHD must be in charge mode or bootloader mode so that it works
I always try to reconnect to the DHD with the PC (windows 7), if t is an OS that it can know the DHD in off mode or the mode "LOCKED")

Hi,
I have the same problem. I ran the ace hack kit on an already rooted phone! It was a big mistake. Currently the phone is not detected by PC and "Recovery" and "Factory Reset" does not work.
By the way, when the bootloader is running, the pc detect the phone, but I don't know how can I do in this situation.
Any help plz.
Download a 1.32 RUU. Select "Fastboot" when you're in the bootloader. Connect the phone with ur pc and run the ruu.
I do what i want, because I can.

READ CAREFULLY AND BE WARNED BEFORE ANYTHING:
THIS CAN HARD-BRICK YOUR DEVICE AND I TAKE NO RESPONSIBILITY FOR THAT!
use it only if you must or not at all
you can read this for some details about what bricks are so you understand what you can get into
this is for all Yoga Tab 2 models 830, 1050, 1380 (regardless of the submodel F,L,LC)
it restores(downgrades) your bios firmware from whatever Lollipop version to the original/genuine one from the latest KitKat stock rom released by Lenovo (and all the latest KitKat stock rom's have 150422 in the rom filename, ie April 15, 2015 and nothing not even minor OTA's were released after this date for KitKat, next ones upgraded KitKat to Lollipop)
useful to:
1. those who want to return back to the KitKat stock rom from Lollipop (if you simply flash back the KitKat stock rom files and you are still on Lollipop bios firmware you will softbrick as the Lollipop bios is a x64 version while the KitKat loader/kernel are ia32 so you will get stuck at efi shells, bios screen etc)
2. those who took the Lollipop OTA, succeded, but had in time problems (bricked their device) and cannot flash a Lollipop stock rom as they don't have one (not being released by Lenovo/available yet and at least some 830 and 1380 models are in this situation), so they must flash back KitKat stock rom and after take the OTA to Lollipop (and the KitKat flashing part put's them in the same situation as those from p1.)
3. those who tried to take the Lollipop OTA and had problems and they tried to flash KitKat stock rom and yet they are failing (this could be due to problems in the updating while OTA was applied, yet could be that their bios firmware was updated to Lollipop version)
4. those who want to test stuff (going down/up between versions) ... you name it...
how to use it:
1. first download and extract the corresponding tool for your device (830 and 1050 models share the same bios firmware so they have a common tool), while at this you can watch the little attached recording i made with the tool restoring the bios for my 1380F tab so you know what to expect when you run it. USE THE TOOL THAT MATCHES/CORRESPONDS TO YOUR MODEL, you can hard-brick if for eg you use the 1380 one on a 1050 model (didn't even tried but nothing good can happen)
2. place your tab in the DnX mode: power off (by force if you have to), press and hold both VolUp and VolDown butons, keep them pressed, now press Pwr to start and release Pwr when it turns on/buzz (but keep holding pressed Vol buttons), in a few seconds your screen will display "Fastboot starting..." and it will hold on that, now you can release the Vols (you are in DnX mode). you must get that message, try again the whole sequence until you succed, don't move on until you have that "Fastboot starting..." on your screen.
3. run the tool (you must have the intel drivers installed, if you flashed to your tab at some point you should have them already), follow the messages i think it's quite easy and straightforward, in a few minutes you will be done and having a brand new kKitKat bios firmware on your tab
(3) if while running it hangs on the "Preparing to push files..." message, and your tab starts to the whatever error message you had before it means that you already have a KitKat bios (the tool works only with the Lollipop bios firmware) so you don't need to restore the bios, you can flash stock KitKat rom directly (in this scenario the tool doesn't modify anything on your tab)
4. when it finishes the tool will automatically reboot your tablet, leave it for a few seconds to start (it will most likely go ninto some efi shell, or bios screen whatever your old files were) afterwards turn it off (long press Pwr) and that's it
5. you can now start in DnX mode again and flash your stock KitKat rom (this step is quite known by now so i won't detail it, there's a lot of info on that in other threads), take OTA's, eat candies... whatever you like
i must warn you again, while i tested this tool (i think i moved from KitKat to Lollipop and back at least 20 times and never had any issue with it) you are the only responsible if something bad could happen, this is playing with bios (and any mistake will hard-brick your tab so you will have to send it to a service for fixing). make sure you have enough battery (while i used the tool even when i was with 5% on my battery i would not recommend, i say at least a 30-40%, the process runs only for 2-3 minutes so that should not be an issue). and of course once it started the flashing DO NOT EVEN THINK OF INTERRUPTING! (you could close other software on your PC that maybe can hang your computer while flashing.. you got the point)
Good Luck!
edit: i already have messages about successful bios restoring (as expected no? ) but failing on completing the OTA to Lollipop update after flashing anew the KitKat stock rom. to them and to all of you people who are going to Lollipop from your newly flashed stock KitKat: SET YOUR COUNTRY CODE!!! after you flash back stock kitkaton the first boot input ####6020# in your contacts and a dialog will pop from which you MUST choose a country (no matter which one, preferably yours or a close one), then after the tab reboots for updating the region and comes back to Android check that you have a country code set by entering #### 59930# and it should show the code you chosed. if you take the OTA without a country set you will FAIL! if you failed on your OTA to Lollipop flash anew the stock KitKat rom and set the country code
also do not take an OTA if your device is rooted, always UNROOT first then take the update, and you can root back after or just don't root until you finished the whole Android installing and OTA updates

thank you! i had the boot to bios problem after trying some not-smart things. after spending an hour on the phone with lenovo this morning getting a repair authorization, i printed out the label. i don't need to send in my 1380f now.

My 1050F cannot boot for long time, I posted the problem(http://forum.xda-developers.com/thinkpad-tablet/general/help-1050f-dead-t3188696) but no one answered me. Today I was very excited to find this post and read it carefully, then tried to do it. But just after the sending progress started (the "xx%" progress began)for about 10 seconds, the program "restore-kitkat-bios-830_1050" vanished(Maybe forced teminated by Windows? I ran the "restore-kitkat-bios-830_1050" after a new reboot of Windows). I waited for about 3 minutes, the "restore-kitkat-bios-830_1050" program still didn't appear, and the tab hanging on a normal picture ( I don't remember, probably a recovery stage picture? but I remember the last line is "the result is Okay"). So I had to disconnct the tab from the computer, and powered it off. Then I try to power it on, but sadly find it cannot boot to any screen. In a dark room, I find the backlight of the tab is on when I pressed the power button, but there is no text or picture on it, regardless of whether I press the power button independently, or press the power button together with any volume button(s).
Now the tablet seemingly has changed into a REAL brick (or hardware brick?). How can I rescue it? The only way is to send it to a service?

i've seen the post with the problem you had, now the thing is on a "normal" bricked tablet (meaning soft bricked one) your tab never hangs at the screen to which you're referring to (Powered by Android) it will always move on (to some error message, bios etc). the same tool was used by me and others (including for your 1050F model last one I recall is @Einwood) and never had issues (until now) so imo it's very unlikely that the problem was from the tool (it's task is quite simple and don;t see what could go wrong) something interrupted the flashing process. also you said you tried both lollipop and kiktkat rom flashing and failed and at least one of them should have worked (the roms are flashed using bios dnx as start) so the issues are with your tab hardware most likely.
but all that is irrelevant now... if it doesn't boot at all and you cannot get it to show ANY message at all (white Lenovo logo doesn't show up when you power on nor does it buzz when pwr on) then service is the only solution
@ The Others: please post your tab model too when posting
Thank you so much for such detailed analysis, but I cannot figure out why the hardware has problem. Yes, now it cannot show ANYTHING, white Lenovo logo doesn't show up nor does it buzz when pwr on. Anyway, I think I have no choice except the official repairment now.
I'm trying to find the LENOVO service sites in Canada, but their Canada official site has no such information, on the contrast, its website is full of sale/order/payment information. I think I should re-think about this company.
Thank you again for the reply.

I'm wondering what your flashing to the tablet with your tool, I have a Lenovo S8-50F and lollipop is pretty abysmal on it, so I'm wondering what your flashing to downgrade the bios so I can try it on the S8, since its very very similar to the 830.

you should NOT use the tool unless it is made exactly for your model, or you most likely will hard-brick. moreover Lenovo uses an in-cpu module for digitally checking the authenticity of the firmware you have on your board at pwr on time and even if you have a bios that would work on your model if it is signed with another key it will cause a hard-brick (the measured boot module will refuse to load the IBB in the new bios).
for eg if one writes the 1051 windows variant of bios on the 1050 android one (they are identical in hardware) it hard-bricks (tested).
send me a link to the latest KK stock rom for your device and i will check on it.
That is what happend to me. My loved 1380f is hard-bricked. Only the white lamp is blinking and it doesn't turn on anymore.
Is there a possibility to repair it or can i throw it in the garbage? Please give me an advice. Thank you very much.

not so much you can do, the hardware is fine, it just got the wrong firmware in it... somehow you must rewrite the bios but you cannot do that from the outside (ie by software means) without being able to boot at least in DnX mode. you can check quickly ... if after you PwrOn (well.. after you long press Pwr button as at this moment Powered On of Off are werid concepts ) you don't get NOTHING on your display (ye not even the Lenovo -> Powered by Android white/black logo) than that's it (try maybe to see if somehow DnX didn't got hooked by entering a fastboot devices and see if by some miraccle you don't see your device there)
your device must be opened by a repairing service tech (especially if he is on warranty), you could do it yourself (i did) but you need the appropiate tools and know/how otherwise from a hard-bricked yet recoverable (the hardware is ok) you will transform it into just a paper holder
updated kitkat bios restore tool to version 2 (foolproof version). read the main thread post at the beginning.
Good morning.
Please let me introduce my situation. I use Lenovo Yoga tablet 2 Pro. On 9-th of november I updated Android to 5.0.1. Unfortunately, one of my commercial aps now can not make a connection with external device (no appropriate information about USB connection is appeared).
I am affraid the problem lies on the Android 5.0.1 system. Before that everything had worked perfect.
That is way I decided to downgrade to the Androix 4.x.
I found above treads, but have some doubts.
Is above tool downgrade my system to Android 4.x or do I need to do some additional operations, to get back to the Android 4.x?
In the section - how to use it (point 5) we can read:
5. you can now start in DnX mode again and flash your stock KitKat rom (this step is quite known by now so i won't detail it, there's a lot of info on that in other threads), take OTA's, eat candies... whatever you like

you must:
1. Downgrade the bios using the restoring tool (you mention "Yoga Tab 2 Pro" so you must use the 1380 version), and you must do that so you can flash KitKat stock rom on your tablet (if you try to flash directly, without the bios downgrade it will fail and you will soft-brick your tablet)
2. After restoring the bios, download from here your stock KitKat rom and extract
3. Flash using Intel Phone Flash Tool (open with it the "flash.xml" from the target_bin directory of the extracted archive). the Intel Tool can be found in the tools directory of the same extracted archive.
4. After you finished sotck KitKat flashing, remember to set your contry code (####6020# in Contacts), also it's not necessary to make your settings wifi etc before you set your country code as they will anyway going to be deleted (a factory reset is performed on country code setting operation). if you don't set a country code you will fail when upgrading to Lollipop.
5. Update using the Lollipop OTA or stay on KitKat
Thank you for explanation.
I download system, installed Phone Flash Tool, open it and chose flash.xml, but after connecting my YT2Pro I can not see device specific with "Start to flash" button in the Device list area of the program.
see below screen. Is this screen looks as it should? (ups, unfortunately I can not post images, because I am new user).
One more thing, tablet should be turned off during flashing?
Right now my tablet is connected to the laptop by USB. It is not switched off and charging is in progress (laptop does not see my tablet as an additional disc/device).
Is above status correct?
