Help: ASUS P835 behaves faulty - Upgrading, Modifying and Unlocking

Hello Friends,
I purchased ASUS P835 in Jan'2010 in India itself. Since then I have been facing many issues and the PDA seems to loose its control once we use 3G SIM card.
It does not hold up the network in good network areas also, and almost all the time, whenever it used to make a data-connection, it got restarted.
Upon complaining, I got the cell-phone replacement.
But with new handset also I face the same issues. Although few problems are not there in the new one, but still the loose network retention and restart on data-connection still prevails.
I understand that this model as a whole is itself faulty.
Can you guys please provide me with some help on this ?
Kindly share, if there is any upgrade or patch available for this.
Also, let me know with your opinions, and recommendations for this cell-phone.
Any help will be much appreciable.
Thanks and regards,
Rohan

SPV M5000 issues with the phone..

Hello,
I have recently purchased a SPV M5000 in used condition and I was able to update the ROM to WM6 however, the phone aspect of this device seems to be working poorly just like it did with WM5 (I thought the update would fix it). It often disconnects and or does not recognize the SIM card’s presence. Although when it connects it works fine but the connection only last a short while, after which point it disconnects and does not recognize the SIM card or searches for service a long time…
I have read through this forum as much as I could but my lack of knowledge in this area prevents me from making much sense of this. Could you ladies and gentlemen lend me a hand in fixing this issue?
Thank you!
i have a m5000 and have NEVER had any of the above problems
My Radio version is 1.13.00, perhaps updating it to a higher version can solve the problem? Can someone help me in this department? which version would it be best for me to try, where can I get it and how to install it? If anyone has the time to help me and break it down for me I would apreciate it.
Thank you.

can i ask u the obvious? have u put the sim in correctly and locked it in? also try locking the battery, sounds like you might have a wonky sim holder?
everything is locked and securely fastened.. I doubt it's the sim card holder.

no gsm, cant install radio rom, plz help, searched no results..

i cant install install any radio rom, my phone says no gsm. i bought the phone on line, and i dont no what rom was it before, but it has no gsm. then i flashed many radio roms with universal ruu-cid bypassing, but cant install..does not move, stuck at 0% then updat error, i have a g3. and i already searched thru the forum. but those didnt help at all...some solutions i found:
- flash with sd storage, he just posted a pic and didnt explain anything and never reply
- check ur id or something and make sure u have the same id? flash it back to original rom- which i didnt no what rom was installed in this phone before...then he didnt explain..
so, im wondering can any1 plz explain step by step how to flash any raido rom, or i have the feeling that its broken anyways, but wanna fix it if i could. thx in advance to all yall nice ppll
Try installing a WM5 ROM and then reflashing the radio. Also check the version of the bootloader, as that may be causing problems as well. I just updated mine to 1.01. Have been looking for 1.2, but the file available ay the wiki section doesn't seem to work. By the way, do you just not get any network signal, or do you get some sort of messages to that effect???
Cheers!
what does the new bootloader do? should i update the bootloader firs and then try to flash the radio rom? or just flash it back to wm6 then update the bootloader? 1 more thing, will any wm5 work?
I've got the same problem too.. I think it's a defect on the motherboard. I am loosing the SIM card at random intervals, I can't get it to happen - it just happens...
I am buying a new M/B I think something went wrong with the GSM part of the UNI.
Ariel
I have the same problem with "invalid sim card" ... As I have friend who's GSM repair guy, I got my card reader replaced, and also tried flashing new radio ROM - still loosing it - occasionally it's "no service", and at other times "invalid SIM"
I'll see if my friend will be able to find some bad soldiering on the MB and maybe fix it (optimistic outlook
If anyone solves this notify me
I think it maybe some microswitch on the motherboard, I switched sims - it's something else wrong with the radio part of the jasjar
--summoner
I had similar problem and it was connected with the metal pin where the SIM card is inserted, since it was not pushed enough to get contact with the module. Try this maybe can help
I tried, bent them some and sprayed contact cleaner everywhere...
nothing
COnsidewring the increasing issues of NO GSM, and as such now we have memory upgradation being done, here is the way to tackle the issue.Pls note and understand carefully what u are doing and then proceed.It involves hrdware skills.
-Open the Universal as per the guide and locate the Qualcomm Chip and Radio section, which is near the antenna.
- Apply the flux on the Qualcomm Chip and hot blow it mildly and carefully.This will eliminate any kind of dry solder and enhance the contacts of the chip.
-Reassemble and Immedialtely flash the Radio ROM only.If u can flash, then when reboot, it will show Radio None, insttead of NO GSM, as in case of Blue Angel.Soft reset again and u are back to normal Radio Version.
I hope this helps.I have been able to recover several Unis with this technique.
So you are saying the radio chip needs to be resoldered because some connection is loose?
What do you think is the reason?
--Summoner
Sorted!
I did as hdubli suggested and it worked! my uni has worked for 18 hours straight now whereas before would lose the sim every 10 minutes or so. Quite scary - although I have a rework station, I have never used it on anything so valuable before!
Thanks for the advice,
John
Cool,
What do you mean rework station? How can I do it myself? can I order this FLUX online?
Can you supply photos or more detailed instructions?
--summoner
Summoner,
a rework station is a hot-air blower used for soldering the very small components found in mobiles and micro-electronics. It is possible to melt all the solder under all the pins of a chip at the same time and if you use a little flux to prevent it ixidising when it melts, you can get all of the joints to be perfectly made. A rework station will cost at least $100US and you do need some practice before you risk your uni, but if you know a local phone-repair shop, they will either have a rework station or know a "man who can". Hdubli suggested reworking the Qualcomm chip in the radio section - the picture in the wiki shows at least 3 Qualcomm chips, so I did them all!
If you're happy with the concept and fancy having a go yourself then google for a local distributor of "aoyue" - they are a Chinese manufacturer of rework kit, and any electronics dealer that sells soldering kit will sell you a "residue-free flux pen". I got mine from Maplin.co.uk here in UK for less than $10us.
hope that helps,
JT
Thanks for your reply... I'll see if to get a rework station, it looks interesting - I know how to solder and stuff. but never used a rework station.
Does anyone have online instructions/tips for using?
--Summoner
www.sparkfun.com has some great tutorials on hot-air soldering and reworking of surface mount components. If you do get a rework station, I recommend a lot of practice on some dead gadgets before you risk your uni!
Best of luck with it,
John
Any luck with this rework method?
I tried to rework but no luck.
no gsm with htc phones/hermes
Hey, just a shot. ATT won't help worth crap and their customer service blows. I found out that if you do a hard boot to flash rom you need to remove the sims card. I am not sure if that is the procurring cause of the no gsm issue, but I don't have a data package and they program that sim to block the gsm! Well, blocking the gsm during programming also blocks your device from setting the parameters correctly for acquiring the imei, radio, and protocol version. DUH ATT! They admitted that they dont service the devices to me on the phone. That's my 2 cents. If it works for others let everyone else know. Now, can someone explain to me how to upgrade to 6.5 and where to start for programing this thing to do great things! Thanks, Ryan

Welcome to the forum
You are in the wrong section
Universal does not means all HTC devices, it refers to a specific model
Try to look into the proper section of your device
Good luck,

[Q] Touch Pro 2 Repair

Hi, I own an unlocked GSM touch pro 2, it's physical appearance is nowhere near new, I was interested in getting a new phone until I found this website and discovered custom roms, I now love this phone and wish to keep it. But the main point of this thread is that I found new housing for my device, but have no knowledge in switching the housing myself. Does anyone know the difficulty of this, or a service where I can send my phone in with the replacement housing for them to do it for me?

[Q] Changing region and language of HTC one x

Hello Guys,
I am a newbie here & would appreciate your help in following matter.
I bought a HTC One X from Bangkok and i m using it in India now.I am facing following issues.
1. I suspect that the phone that i bought was AT &T locked phone earlier and i might have been cheated by the seller in this regard. My question is how do i confirm whether this is an AT&T unlocked Phone?
2. The language of applications installed on the Phone is chinese and i cant seem to get rid of the language even after changing the language from settings page. How do i get it to be in English completely?
3. Indian carrier SIM apart from CELLONE does not detect or register on any network here. and the SIM slot is a normal one not a micro SIM Slot. Does this Phone require any special kind of SIM card?
4. Even Google Play is not there. whenever i try to download anything a page in chinese opens up. And i do not know chinese.
4. Will rooting of my phone help in any of these regard? I even dont know whether this Phone was a rooted one.
Please Help somebody....
Thanks & regard..
Nix.
You are the proud owner of Chinese knock off. Sorry to hear you got fleeced.

Well i am sure that its not a chinese knock off atleast.. but this may be AT&T unlocked, that i am confused about...
Got to<settings <about<software information. Take a screenshot and post here.
here is the screenshot.. plz help dude.. i am all confused right now
Looks like it could be a really old build of HK firmware, but the kernel date doesn't make sense.
Try flashing the latest HK RUU (1.29.708.15) http://www.filefactory.com/f/7cc7b2fbdd03c031/
I'll leave it to you to find a username and password that works, but it's been posted in this forum more than once.
Strange, Also you mentioned that the phone takes a full sized sim not micro sim. Check the HOX's spec sheet and you will find that they were manufactured with micro sim slot only.
Maybe it IS a knock off OR someone modded the build.prop and sold you a Desire X?
i am uploading my factory mode screen. Please see if you guys can help
The number of speaker holes are less that the genuine one x. I think you have been fooled. The Hboot that you have is different. Check the attached pic.
Well this just gets stranger and stranger.
Doesn't look like a real One X I'm afraid.

yeah, it definitely seems that i have been fooled now. Any ways, is there any way to know the device hardware configuration, so that i may be able to flash it to atleast use it here in India.
Is there any ROM compatible to any handset?? If so, Then how do i go with it?

I was trying to be sensitive in my previous posts, and felt for you. Best you leave the rom as is, chances are if you try flashing you could end up with a brick.
sorry to bring this post back to life.. but need help.
my cousin from europe gave me his old HTC One X for my parents to use. but they need that to be in traditional Chinese language system.
can someone help me? I have posted up the SW and kernal version for your reference.
Thank you.

WiFi Issue

Well i just got a brand new Moto Z2 Force and as I was setting up, i noticed the WiFi connection stopped working from time to time. I thought it was mi WiFi network, but issue was persistent on any WiFi network. I bought it on December 30, 2017
What I have done so far:
- Restore to its factory settings (didn't solve the problem)
- Update software 7.1 (didn't solve the problem)
- I took it to the carrier I bought it from, (They kept it for 12 hours to monitor its issue) (didn't solve the problem)
They told me, since its not a carrier issue, I should contact Motorola directly.
- I called Motorola support, and they told me that the phone needs to be sent to be repaired. Since its a common issue regarding WiFi and Bluetooth connectivity, what really pissed me off, was the word "repair", i explained that, why I should get a repaired/refurbished phone, since i pay full for a new phone and they explained that, thats how Motorola respect their "warranties". Repairing a defective device.
Since I live in Mexico, warranties here are a big pain in the ...
I know carriers in the US, have a 15 or 30 day, hassel-free return policy. But in Mexico, once you take it out of the box, its your problem.
Im pretty annoyed since I have the Moto Z Play and this phone works perfectly, thats why I went for the newer Motorola. Since I know how Motorola respects their warranty im never buying a Motorola again.
UPDATE
After going back and forth, the carrier decided that was a DOA phone and gave me a brand new one. I'm been using it for a week now and no issue whatsover.
Just some bluetooth disconnections from time to time, but i can live with that hoping for a software update fix.
Hi there!, calm down, i'm here to save you, but first off, i'm form Mexico too, and yeah, thw warranty here is some kinda tricky, but with Telcel you got the option between 30 days after the purchase to get a new one. But whatever, that time passed already.
Ok, first, tell me if you got the next issues:
Sudden disconnections
Horribly and stupid process to connect after a "breakdown" happens.
When you were connected (Luckiest thing ever), did you noticed that sometimes the speed goes like ZERO kb/s, it tooks like years to load an HD video form youtube?
If your phone shows all these sympthoms, welcome to hell, and i got some good news for you, the problem is not 100% the phone, for some reason, this problem starts when you update all the stuff form Play Store. So the phone is "physically" OK.
If you want further assistance you can send me a PM with your phone number, i'll be in touch shortly.
I'm glad to help you.
He’s not the only one with this problem. Would love to know your miracle solution!
I also have the same problem but it works PERFECTLY with 5 GHz Wi-Fi AC. Take a new wifi router

OT - I'm sorry, but this smacks of a scam. You don't need a phone number for anything, and if you have a fix, post it for others to use. What could be so secret as to warrant a PM.
I have had WiFi drops / performance issues with other devices with the same chipset, and it was fixed splitting the 5 and 2.4 into separate WiFi connections.

Hi there, first off, you have to turn on the phone in Secure mode - Long press "shut down" and then accept to turn on the Phone in secure mode.
Then, you have to test the wifi functions in this mode, if everything works fine, the problem it's not something about the HW of the Moto Z2 Force, but the problem it's a process which is causing this wifi disconnections, slow wifi etc..
Now you have to identify which process i scausing this, if you ask me, i've found that Google Play Services i scausing the problems, so i've tried many different versions and now it's working great, no wifi disconnections, FULL speed, and no other problems.
Let me know if i can help you out with more information, sometimes it's hard to write through a phone jaja.

Wanting to file class action lawsuit
Well it's as plain as I can make it; after attempting to contact support for help with my Z2 Force's WiFi issues; which go figure I find out is a known issue since DAY 1. They won't fix it because the warranty ended 11/18/2018. I explained I found over 17 pages on just Lenovo's website of issues and Motorola and Lenovo did nothing. They still won't do anything they want 150$ to look at it and then they may give me a replacement z2 force. I've had enough I am starting the process of a class action lawsuit against Motorola; and Lenovo and I wanted others to reach out to me. If you've had issues please contact me. Thanks
Rob
My s z2force (1789 05) sometimes disconnects the network (including wifi). When playing games, it is usually used. I feel that this is not a big problem. I was on a lg v30. This problem is more serious.
