Ok everyone. My bad luck i purchased the used HTC Shift. The hard disk is generating the bad sector very rapidly and with in a matter of hours i found that by using HDD regenerator that my 90 percent of hard disk is damaged by bad sectors. Do this mean that the device i purchased is dropped by his owner or this is normal with HTC Shift devices.
Can someone confirm if i use the 5mm or 8mm 1.8" hard drive? plus do this is hard disk issue or may be some connector or something?
Solution: I got the warranty!

Ok so I'm stupid.
Whilst trying to boost 3g reception and having plugged an external antenna into my gsm external port (the one on the left). I have damaged my kaiser. Now when I remove the external antenna the internal antenna no longer works. I get no reception whatsoever.
I presume there is some sort of physical switch in the port which has been damaged by plugging in the external antenna.
Do any of you guys know about this and if it can be fixed (say by soldering the port)? Any help (other than insisting that the phone will just have to be replaced) appreciated.
bump up - please help
Not a total loss
Looking at pg 92 of the Kaiser service manual, I see there is just the earth connection on the pcb either side of the connector and a single track down the middle so I cant see how there would be an isolator switch built in. Theres nothing about using the RF connector in the user manual (only the GPS connector) and plugging in an external RF antenna, as well as requiring the correct part (and I don't know if this connector is for an antenna or just testing purposes), would require removal of the battery cover. I think you may have damaged the RF circuitry/receiver. Have you tried removing the battery for a few minutes, attempting to power up the device (to remove any residual charge), performing a hard reset and trying again in different locations (assuming you haven't changed anything since it was last working fine)?
I don't think the phone would need to be replaced but it may require some components to be replaced by a service centre that knows the device well if none of the above makes any difference.

Thanks for your comments. I have removed the battery but I have not tried a hard reset. I'm out in africa at the moment and can't deal with the other problems this would cause.
Right now I have temporarily fixed it by bending a paper clip and putting it in the port with the rest fitting snug under the cover. The reception is surprisingly good.
If the temporary fix works....

Hi I had 6 months ago a second hand HTC tytn 2, has been working very well till last week. I been watching the movie on my phone which was stored on memory card (4GB SanDisk Micro SDhc). Then I deciced to put some more tunes on my phone... so I went downstairs first to get drink after I pluged phone to PC and I found out that somehow my HTC can't detect the card... So after 2h of taking card out and in I decided to reset the phone to producent setings. However that didn't helped i tried to download some kinds of ''sdhc fix drivers'' but its also didnt work. Today I woke up in the morning and I recognised that on my phone that sim card is missing... but is in the phone so I tried to clean up the place where sim card is ... I took card out and in few time as well but still nothing .... I reseted device to originals setings again but its failed as well... I was operating WM 6 and today i changed to WM 6.1 and I upgraded the radio to new ones because I was thinking that it may be the case.
Any advice because im quite noob.
Thanks
there are a few threads about similar issues...you can search for these threads to learn more information about your issue.
i can guide you about the possible cause. if you notice, BOTH of the items that are failing (SIM and memory card) are located in the top half of your device...the half that carries the screen and slides over to uncover the bottom half that has the keyboard.
this leads to a design that involves mechanical moving parts...and so there are "ribbon cables" that connect the various parts in the top half (SIM cradle, memory card cradle, front buttons, screen, touch pad, ear piece, notification LEDs) to the motherboard in the bottom half.
...and mechanical and moving parts often cause wear and tear and, eventually, these delicate ribbon cables can come loose or even break. my bet is that the cables for the SIM cradle and memory card cradle have become faulty. try to see if your device has better luck in detecting the SIM and/or memory card with the keyboard slide out.
also remember to search for other threads about such similar issues.

I too have similar problem with my TyTN II. First it started with the SD card detection problem followed by intermittent SIM card detection and recently the failing of the touch screen. My unit is coming to 2 years this March. The hardware is still in a very good condition as it is always protected with the phone pouch supplied.
Can the "ribbon cables" be replaced? My HTC agent in Singapore quoted me S$700 to replaced the mother board. They are telling me indirectly to buy a new phone instead. Their advise is very sad.
You can buy a new main flex cable on ebay for about £25-£30 GBP, possibly cheaper, it's a full disassembly job to fit it, you will need to be confident in your ability to completely dismantle the device and put it back together again.
Hi All,
I've got a tytn 2 (kaiser) and its having some problems. Basically the keyboard is stuffing up (again) and it won't read SD cards. I've changed sd cards etc etc and still no joy. What I'm wondering is if there are parts that I can buy to fix this problem? I know I can buy a keyboard but can I dismantle the phone to fix the card reader side of things?
Its worth noting that I have also tried to reflash the phone from the micro sd card, and at that stage the device cant even read from the SD card. This makes me think its an actual hardware failure.
Thanks,
Lewis

Oh ok that helps. So where would I get parts for my kaiser? SD card reader etc.
Unfortunately I have no clue....
I would say check the threads about replacing the LCD panel, and the stores that have that, or the digitizer might have the LCM (Lower Control Module) that has the SD card slot
I've seen digitizers and housings -- but I'm afraid that for a lot of parts you'll have to buy an old Kaiser...
I have an LCM with a damaged flexi, the sd card slot should be fine, not sure how easy it would be to remove, or replace, it may be possible to do this if you have access to professional desoldering tools, or know someone who can do this for you.
Yeah well I got the kaiser to pieces, not sure how to get it back together lol
I think this will be my last HTC device. Looking at how it is made, the phone is 40% screws and 60% glue. It makes sense that when the device would warm up sufficiently that the glue would go everywhere. It just seems shoddily built.
I'll attempt to put it back together for one last boot to get my contacts etc however i'm not that hopeful. I think I'll be jumping to the nokia n900.
I have a KF2 which I managed to get twrp on, but the partitions seem to be messed up in some way. When I boot to recovery and do an adb shell, ls /dev/block, there are only loop and ram devices shown. The emmc chip seems OK though, since I can transfer a CM rom to it, but I can't write it to become 'working'.
When I try to wipe or factory reset from recovery, I get an error to the effect that none of the partitions can be mounted. IE
unable to mount /data, /cache, /system, /efs, storage, /data/media during gui startup
also:
unable to find partition size for /boot, /recovery, /bootloader
So I should probably describe how I got here. I was sold a KF2 as a KF1 so assumed it was KF1 and hence bricked it (didn't check for the otter2 id). I opened it, soldered to the main board as described in other threads, dd'ed the working otter2-u-boot-prod-10.2.4 file directly to /dev/sdf2 on the emmc from my ubuntu desktop. Then put it back together and used fast boot to get otter2-twrp-2.6.3.1-recovery.img and otter2-freedom-boot-10.4.6.img on it. Then transferred CM rom to /sdcard with adb push. Rebooted and tried to continue the CM install but when I get to the wipe part, it fails with the above errors. Even from 'advanced wipe' it still says the same (unable to mount etc). Factory reset the same too.
So I took it apart again, connected it back to the computer, and used gparted to examine the file system. It seems OK, it had an error at first (primary gpt corrupt or something, using backup - I think gparted fixed that for me) fairly consistent with what the guys in the emmc soldering thread see. Then back to the kindle boot, same thing happening as before. Eventually I reformatted each ext4 partition using gparted (from the desktop) to try to fix it, still no joy.
So reading lots of threads here by soup and hash, I tried several of their solutions, like fastboot oem format (I had to put the device ID in there to make it work). None of them have worked.
So when I do a:
adb shell parted /dev/block/mmcblk0 print all
I get:
Error: Could not stat device /dev/block/mmcblk0 - No such file or directory.
(and /dev/block/mmcblk0 does not exist - the only files in that dir are ram0, ram1 etc, and loop0, loop1 etc)
That seems like the problem to me. Twrp is not seeing the emmc at all it seems - even though its loaded off the emmc AFAIK? Which seems weird. Surely the device is able to see the emmc and the first few partitions if its booting to twrp - but once in twrp, none of the partitions - or even the device mmcblk0 - is showing up at all. But when I connect it back to the PC, gparted is happy with it all - although all the partitions show up as microsoft type which seems odd. But I can mount them and browse them (the ext4 ones).
Anyone throw any light on this? BTW the wiring is unlikely to be causing this problem because I disconnect all the wires from any 'interconnections' when I put the kindle back together. Although the wires are still connected to the main board, there are no bridges between dat0, dat1 etc, as I am using a connector to isolate them.
EDIT: And theres this in dmesg, which seems suspicous:
<4>[ 1.053588] mmc0: host doesn't support card's voltages
<3>[ 1.053588] mmc0: error -22 whilst initialising MMC card
<4>[ 1.067321] wifi_set_power: 1
<4>[ 1.118896] mmc1: card claims to support voltages below the defined range. These will be ignored.

Well I fixed it, thought I should post back here as its an interesting fault.
Turned out 2 of the pullup resistors were open circuit, obviously my fat fingers and bad soldering! I found it because looking through the datasheet for the emmc chip last night, I noticed that the chip needs pullup resistors on several of the pins (last page of KLM8G2FE3B datasheet which you can find online). Thinking back to the mainboard in the KF2, I remembered the grid of resistors and thought maybe they were the pull up ones. Reason I was thinking about this at all was I wondering if the chip can be ripped out and replaced with a very large SD card, but thats for another day.
Anyway I thought I might buzz out the data lines and CMD as these are the ones with the pullup resistors, to check my soldering. IE I should see the same resistance on each (with respect to +ve). Well 3 of them were 10k, which seems about OK although the datasheet recommends 50k, but this seems in the right range. But 2 were 450k ish. Far too high. If the resistors were blown then this is the kind of resistance I expect to see, back through the memory chip rather than through the pull up resistors to +ve. The bad lines were data1 and CMD btw. Really hard to solder, and I ended up having to solder to the resistor on both, with the result that the resistors blew.
The reason the emmc chip seemed ok when plugged into the computer is probably because the SD card reader provides these pull up resistors in it, making the ones on the board redundant. When the SD is unplugged, there is no pullup on those lines, and the chip is hence not readable - although I am still confused as to how it booted at all, maybe initial boot is only at a reduced data rate which didn't need the pullups, I don't know.
Anyway I put a couple of 10k resistors I had laying around between the still soldered on SD adapter and +ve, so effectively replacing the on board pull up resistors with the external ones. I was then able to install CM and get the tablet running. Since there was not room in the tablet for these large resistors etc, I spent several hours today trying to solder on tiny wires, and solder a couple of smt 10k resistors in place of the test ones. I succeeded eventually, with the wires coming from the rear of the main pcb where most of the wires connect in the 'rescue kf2 with soldering to chip' thread, and then the wires go round the pcb edge to the other side (that you see when you take the back off the tablet). Theres more room this side, and I soldered the new smt resistors on to the wires, and eventually got it working again.
I didnt replace the smt resistors where the old ones went because I simply can't solder this small. It was hard enough connecting those 2 wires to the 2 solder pads. Took hours. Not worth it considering I only paid 13 quid for this tablet but satisfying to fix.
I put this here in case anyone ever finds it useful - perhaps for other things. I still wonder very much could the emmc chip be ripped out - perhaps a large soldering iron held on the back of it for a couple of mins would allow it to float off - and could a micro SD be connected to the 8 solder points used for the rescue project? Looking at the emmc datasheet it seems exactly like an SD card. It can be read and written like an SD by an external computer as we can see from the success of the recovery project. I have made microcontroller circuits (atmega etc) which read and write SD cards and its not rocket science. Part of me wishes this KF2 had been unrecoverable so I could try it. Its something I might try if I pick up another kf2 sometime. But for now enjoying tinkering with this one. I intend to study the datasheet a bit more, see if its completely compatible with the SD protocol, and if so try it. Might post another thread sometime asking some of the more experienced guys here if they have any idea if it will work.
@peterpion you probably saved my day! been pulling my hair trying to figure out why fastboot would work with flash but TWRP wouldn't see the MMC card at all. I essentially destroyed one of the pull up resistors during soldering. Must be this!
Hi all!,
I am desperately seeking help!I have all my baby's memories in this SD card. Somehow it got fried... I was thinking it was the phone that I had. It was a refurbished phone and on the same day I got it it started acting up, screen would turn on and off. The next day sd card wasnt recognized by the phone anymore. we were looking for ways to figure it out til we end up in a youtube channel "recoverfab" that digs in to the sd card microscopically to analayze and extract datas So we sent it to them..in Germany ,But.. with no luck. They have emailed me... i will attach this at the bottom. Please somebody... there must be hope somewhere! These files i have there are all precious one time snapped memories! Please! Help!!!
Dear Ms. Santos,
Unfortunately, it is not possible to rescue the data from your order # 11088. We assumed the controller on your memory card is damaged. In these cases, we try to read the raw data out from the masked wiring from the back side of the card (see the photo from the backside of your card in the attachment), but it failed. It was not possible, to establish a connection to the embedded memory chip. The reason is a physical damage. That circumstance makes the data rescue no longer possible. The following causes for the failure of the storage medium come into question: a)A short-term voltage peak occurred from a connected device destroyed an electronic module in the memory device b)A previous production damage in the device, which has deteriorated by the continuous heating and cooling during the use and eventually lead to failure. c)An alpha particle, emitted by radioactive contamination of the storage medium materials, has struck an electronic component and destroyed them.
This analysis is free of charge. If you would like the storage medium to be returned to you then notify me within 3 days and pay 10 Euro (with a note to your order number: 11088) via your own PayPal account to [email protected] or requesting bank details. This shipment will be executed with the regular mail. You can also organize by yourself a courier service with the pick up.
