Hi,

ZTE Blade, bought on 31.3.2011

Glass:TRULY

touchscreen module
name: synaptics
i2c address: 0x22
IC type 2000 series
firmware TM1541
module synaptics + TPK

Baseband P729BB01
Kernel 2.6.29

Build YESSS_P729VV1.0.0B02
------------------------------------------

I have tried:
Swedish_Spring_RLS3
Swedish_Spring_RLS2
Touchscreen works after flashing and booting from clockwork, but is dead after power off/on. IIRC it was functional again when booting through clockwork, but I might be wrong with this.
--------------------------

cm-7.0.0-RC4-Blade-signed
r12-update-modacocustomrom-blade-kitchen-unsigned
Swedish_Spring_RLS4b
All of these show a dead touchscreen right after flashing and booting without a chance to come alive.
--------------------------

Interesting: Swedish_Spring_RLS4b behaves like the others, whereas Swedish_Spring_RLS3 and Swedish_Spring_RLS2 did at least work from the start.
Any ideas what difference between RLS3/4 could break the touchscreen?

Of course I'm willing to help with further information when needed. Hoping to get a solution in return

Have exactly the same Blade (I guess you got it also from Hofer?). Running CM7 RC4 right now, touchscreen did not work after flash and reboot but pulling the battery for some minutes did the trick and it runs now without any problems. After a reboot the touchscreen might not work again, but pulling the battery always fixed the problem.

Also the stock rom does not always work from start and I had to pull the battery.

[fredl99]

Hi,

Yes, it's a Hofer-handset. I wonder how you could GUESSS that

Thanks for the hint regarding battery in/out. I will try that again. Anyway, I wouldn't consider this a practicable solution.
If I had this problem with the stock ROM it would be a reason to return the item. (To all the other readers: These devices are usually sold out within minutes, so there's nearly no chance to get a replacement.)

--------------------
To me it seems ZTE is following a popular Chinese habit by delegating the final quality tests to the customers. I see no other reason why obviously identical devices would produce so different behaviours. If this is true then developers will be hunting bugs forever, because there will always be one handset out there showing its very own fault after a supposed bugfix.

There seems to be software issues as Sebastian404 assumes

Sebastian404, on Apr 2 2011, 16:10, said:

The issue seems to be that ZTE *SEEM* to of forked development into 2 directions, (for cost reasons) they seem to be using different hardware in newer 2.1 production devices and adding driver support to the 2.1 builds, but not adding the same hardware support into the 2.2 builds...  it is possible we will eventually see the alternative hardware support in offical 2.2 builds and it will level out....

but there are also reported hardware issues: [German] Touchscreen reagiert nicht mehr

the holding the back button does seem to work for me, but now once booted this way, the screen doesn't automatically switch it self off, only the back light.

Any one else with similar issue?

If I remove battery for approximately 10 minutes, everything is OK.

If it has problems on 2.1 your digitizer is broken / the connector is flaky. I would take it back as it may make problems in the future.

@all people with screen problems, did you try to convert your phone to Gen.2? Look at the stickies, maybe it will solve the problem.

[EazyDuz]

Im gonna wait for someone else to switch to gen 2 first

I had problems with not responsive touchscreen after flashing any custom roms.

When I switched to Gen2 problem is gone from now. I'm using SS RLS4b.

Can anyone confirm this? Please note that there is no secure way back to gen1. Read this http://android.modac...flash-solution/ first

I don't think it's related with Gen 1/Gen 2 in general... The phones work with the stock build (romdump of the new YESSS software build B02 is here: http://www65.zippysh...59344/file.html - the old YESSS version B01 can be found in the stock rom thread). It may be just a driver issue, they definitely changed something in the newer build, we just have to figure out what.

For example the kernel configs of the two versions differ:

< # Fri Nov 19 12:12:26 2010
---
> # Thu Feb 10 07:43:29 2011
949c949
< CONFIG_SENSOR_LIS302DL=y
---
> # CONFIG_SENSOR_LIS302DL is not set
950a951,952
> # CONFIG_SENSOR_ADXL34X is not set
> CONFIG_SENSOR_ACCELERATOR=y
1110c1112,1115
< # CONFIG_MT9P111 is not set
---
> CONFIG_MT9P111=y
> # CONFIG_MT9P111_MCNEX is not set
> CONFIG_MT9P111_SAMSUNG_FPC=y
> # CONFIG_MT9P111_SAMSUNG_SOCKET is not set

@Rotmann: I don't think it is a hardware failure, if it would be, it wouldn't work with the stock rom without problems

Any ideas as I am keen to get this Orange firmware off my phone !

Some people say they have problems on stock 2.1 too, that's definitely an hardware issue.

Upgrade to Gen.2, one guy confirmed it worked.

[Fadox]

Right now i can't unlock my phone(from one operator to another) and my touchscreen doesn't work if i change to any other rom(even stock orange 2.1, i currently have optimus rom- portugal). IF i upgrade to Gen.2 will this solve my problems???

Thanks

today i got my old blade back from the repair shop. they replaced the digitizer. working fine. i thought i would try CM7 out and got the same problem of no touchscreen after reboot.

strangely, if i boot to CWM and then reboot from there it seems to work, though touch screen seems a bit flaky after the phone goes to sleep. i wonder if it could be a software/driver issue with not waking up the hardware? anyway, it's early days so will see how it goes...

Worrying, I just got a replacement refurbished phone today, not flashed it yet.

I wonder if the old hungarian tpt would cure it?

What are the differences between b19 & b20 roms? has anybody compared the files?

[isambard]

everything seems to be working now. i wonder if it was just a temporary glitch? maybe those having a problem can try after flashing cm7, rebooting via cwm and then turning off and leaving it for a few minutes before restarting. also remember to wipe cache.

[wbaw]

I just installed the tpt backup of cm7 from my old phone to my new one, no problem with the touch screen at all. I didn't try installing any custom roms with clockwork first, looks like a tpt could fix it.

I've just flashed a B10/B20 phone, and it worked fine with a normal flash.. so I dont think the B10/B19, B10/B20 is actually anything to worry about.. seems to just be a few random phones have issues..

I bought Orange San Francisco a week ago.

I've installed CM7 RC4 on it. After few reboots i was not able to unlock the screen - touchscreen stopped working. I've reflashed CM, but after reboot same reappeared.
After some tests/reboots/ets i've noticed that the screen will work if after reboot do not touch the phone and wait until screen will dim a bit - then it is starting to work (but not wait until it will off, i miss this moment reboot needed). I was thought that it is RC4 problem (din not found something in CM forum) + some random reboots, so i've decided to flash something more stable. Swedish Spring - i was surprised when after second reboot same happened And this time i'm not able to unlock the screen inany way. I've flashed JJ - same thing

Update: just flashed CM nightly 36 - 4 reboots without problems. But it is to early to start celebrate, problem could be back in few reboots later..
